The upper end surface of the support block 4 is in rigid contact with the pressure cover 2, and the lower end surface is welded and fixed to the water tank top plate 111.

[0030] The water tank top plate 111 is provided with three bolt holes in each direction, with a total of twelve. A first elbow plate 5 is provided on both sides of each bolt hole. The first elbow plate 5 is triangular and is located on the reverse side of the water tank top plate 111. One side is welded and fixed to the water tank top plate 111, and the other side is welded and fixed to the water tank side plate 112 to ensure strength.

[0031] The water tank 1 is provided with three support members 6 in both the horizontal and vertical directions. The support members 6 are unequal angle steels, with a total of six. They are welded and fixed in pairs at the horizontal and vertical intersections. The horizontal and vertical ends are welded and fixed to the water tank side plates 112, and the lower ends are welded and fixed to the water tank bottom plate 113. A second toggle plate 7 is provided at the contact position between the support member 6 and the water tank side plate 112 in the horizontal and vertical directions. The second toggle plate 7 is rectangular, with three side surfaces welded and fixed to the water tank top plate 111, the water tank side plate 112 and the unequal angle steel support member 6, and the other side surface is a free edge.

[0039] It is worth pointing out that during the sealing test, the discharge pipe 8 must be blocked first, and after the water tank 1 is filled with water, the gland 2 is lifted and installed in place using the eye plate 14. During installation, the test rubber 17 must be installed in the rubber groove 11 in advance, and it is noted that the bolt holes on the water tank top plate 111 must be aligned with the bolt holes on the bolt clamp 9. Then the water tank 1 and the gland 2 are fastened together by bolts 18, nuts 19, and gaskets 20 to ensure that the compression of the test rubber meets the requirements. Finally, water is injected into the water tank 1 through the water inlet pipe 15. When water overflows from the water outlet pipe 16, the water injection is stopped, and the water inlet 15 and the water outlet 16 are blocked. After standing for three minutes, observe whether there is water leakage at the rubber seal contact to verify the tightness function of the test rubber under the required water pressure.
