Full Text	FORM 2 THE PATENTS ACT 1970 (39 of 1970) & The Patents Rules, 2003 COMPLETE SPECIFICATION (See section 10 and rule 13) 1. ' A BIOGAS DIGESTER COVER WITH BRACKETS. 2. (A) SHENZHEN PUXIN SCIENCE AND TECHNOLOGY CO., LTD. (B) A COMPANY INCORPORATED UNDER THE LAWS OF CHINA (C) Rm. 309, Park 2, Shenzhen Oversea Chinese Founder's Park in Long Gang, Shenzhen, Guangdong 518172, CHINA. The following specification particularly describes the invention and the manner in which it is to be performed. The present invention relates to a removable cover of a hydraulic biogas digester and, more particularly, to a biogas digester cover with brackets. Background Art The Chinese Patent ZL03201184.3 "Foldable Biogas Digester Cover" disclosed a structure of a removable cover for a biogas digester, wherein three reinforcing beams are installed on top of the cover body, and a removable locking device is installed on the reinforcing beams. The removable locking device inserts into the inner wall at the opening of the biogas digester, so that the removable cover can be fixed inside the opening of the biogas digester. When biogas is stored in the removable gas cover, the removable gas cover cannot float upward because it is fixed inside the digester. In practice, removable gas covers with such a structure can satisfy the application requirements of biogas digesters. However, in practice, flaws are found in removable gas covers with such a structure. Since the cover body joins the opening of the gas digester by three reinforcing beams to fix the cover and prevent it from floating upward, i.e. the three reinforcing beams push down the gas cover from the top thereof. When the removable gas cover is under the pressure of the gas inside the digester, the cover body, under the restraints of the three reinforcing beams, is prone to be deformed. Therefore, the existing cover body is required to have high anti-deformation rigidity and strength. This increases the production cost of the removable gas cover and it also affects the life span of the removable gas cover due to its inappropriate structure. Summary of the Invention The present invention aims at overcoming said defects that exist in said removable gas cover of hydraulic biogas digesters and provides a gas cover with brackets which can dramatically lower the anti-deformation rigidity and strength requirements of the cover body, so that the production cost of the gas cover can be greatly reduced and the life-span of the same can be extended. The biogas digester cover with brackets of the present invention includes a cover body with a gas nozzle, wherein a reinforcing ring is provided at the opening of the cover, and at least two brackets are provided on the reinforcing ring of the opening at the lower edge of the cover body for fixing the cover body inside the opening of the biogas digester. Three brackets are provided on the lower edge of said cover body. The design principles of the present invention include: fixing the gas cover at the lower edge instead of at the top, i.e.: moving the point of force to the lower edge of the cover body, wherein the point of force prevents the cover body from floating upward and fixes the cover body, thus the cover body can keep its natural hemisphere shape without being deformed. As the gas cover is fixed by the brackets mounted on the lower edge of the cover body, it is only required that the lower edge of the cover body have high rigidity and intensity. Since there is no requirement on the rigidity of the cover body and little requirements on the intensity of the same, the cover body can even be a soft body. Such a change in structure results in more reasonably assigned stress on the cover body and dramatically lowered requirements of rigidity and intensity on the same, thus the production cost of the cover body can be greatly reduced and the life-span of the gas cover can be extended. The biogas digester cover with brackets in the present invention is scientific in design, reasonable in structure, and convenient in application. By making use of the brackets provided around the opening of the cover body, the gas cover can be handily fixed inside the opening of the biogas digester with pins. Not only does the present invention have the functions of the removable gas covers in prior art and satisfy the requirements of normal use, but also overcomes the defects of the removable gas covers in the prior art, such as overall strict requirements of material, high production cost and short life-span. The present invention is a removable gas cover that better satisfies the application requirements. The detailed structure of the biogas digester cover with brackets in the present invention will be given in detail in the following figures and embodiments. Description of the Drawings Fig.l is a schematic diagram of the structure of a biogas digester cover with brackets. Fig.2 is a schematic diagram of the breakdown structure of the biogas digester cover with brackets as is shown in Fig.l. Fig.3 is a schematic diagram of a kind of bracket. Fig.4 is a schematic diagram of another kind of bracket. Fig. 5 is an enlarged schematic diagram of the structure of part A of the biogas digester cover with brackets, as is shown in Fig.2. Fig.6 is a schematic diagram of the installation of the biogas digester cover with brackets on the biogas digester. Detailed Description of the Embodiments Embodiments: As is clearly shown in Fig.l and Fig.2, this is a biogas digester cover with brackets that has a gas nozzle 12 provided at the top thereof and comprises a cover body 1 and athree brackets 2.
