Problems solved by technology

[0002] The existing water tank cover is an integral structure. An angle iron is welded at the water inlet of the water tank cover. The angle iron is used to weld the pipe. The welding of the angle iron causes a bulge in the middle of the cover plate, and its surface is uneven, which affects transportation and aesthetics. At the same time, the existing cover plate only uses the pressure bearing capacity of the steel plate as the load, its strength is not high, and its shock resistance is not strong, and it is connected to the pipeline by welding. Synchronization, a series of self-balancing stress and self-coordinating deformation will be generated inside the structure, resulting in weld cracking and water leakage, and difficult maintenance and disassembly

Embodiment 1

[0032] Refer to attached Figure 1-2 , a water tank cover, including a cover body 1, the cover body 1 is composed of a plurality of cover plates 2, and the cover plates 2 include a first cover plate 21, a second cover plate 22, a third cover plate 23 and a fourth cover plate The cover plate 24, the structure and size of the first cover plate 21 and the second cover plate 22 are the same, and the structure and size of the third cover plate 23 and the fourth cover plate 24 are the same.

[0033] The first cover plate 21, the second cover plate 22, the third cover plate 23 and the fourth cover plate 24 all include a plurality of concave plate structures 211 and a plurality of convex plate structures 212, and the plurality of The concave plate structures 211 and the plurality of convex plate structures 212 are arranged alternately.

[0034] Further, one side of the first cover plate 21 and the third cover plate 23 and one side of the fourth cover plate 24 are welded, and the othe...

Embodiment 2

[0045] In this embodiment, the section of the convex plate structure 212 is an isosceles trapezoidal structure, when it is under pressure, the total pressure ΣF will be divided into the support force F1 received by the horizontal plate of the convex plate structure The inclined support force F4 received by the longitudinal plate of the plate structure 212 and the support force F3 received by the plate surface of the concave plate structure 213, the inclined support force F2 includes the vertical support component force and the horizontal component force, thereby further increasing the support capacity of the water tank cover. Refer to the attached force diagram Figure 4 .

[0046] To sum up, the structure design of the present invention is reasonable. By dividing the whole cover body into multiple cover plates, it is easy to transport, and the four cover plates are identical in pairs, and the process is simple; multiple cover plates are folded, Make it a wavy-like structure ...

Abstract

The invention provides a water tank cover. The water tank cover comprises a cover body, wherein the cover body consists of a plurality of cover plates. The water tank cover is reasonable in structuraldesign. The whole cover body is partitioned into the plurality of cover plates, and the plurality of cover plates are subjected to edge folding treatment respectively to be of wave-like structures being depressed and protruding alternatively, so that the strength is enhanced. When the cover plates are under collision, the wave-like structures are deformed to form buffering, so that the anti-shockand pressure-bearing capacities of the cover plates are improved. The water tank cover is constructed by splicing four cover plates which are the same pairwise, so that the water tank is convenient to transport. Meanwhile, the water tank cover is detachably connected with a water inlet pipeline through a bolt, so that the airtightness as well as the connection toughness between a water pipe and the water tank cover are improved.

Description

technical field [0001] The invention mainly relates to the technical field of water tank covers, in particular to a water tank cover with high strength and good shock resistance. Background technique [0002] The existing water tank cover is an integral structure. An angle iron is welded at the water inlet of the water tank cover. The angle iron is used to weld the pipe. The welding of the angle iron causes a bulge in the middle of the cover plate, and its surface is uneven, which affects transportation and aesthetics. At the same time, the existing cover plate only uses the pressure bearing capacity of the steel plate as the load, its strength is not high, and its shock resistance is not strong, and it is connected to the pipeline by welding. Synchronization, a series of self-balancing stress and self-coordinating deformation will be generated inside the structure, resulting in cracking of weld seams and water leakage, making maintenance and disassembly difficult.
