[0002] With the development of urban construction, the treatment of sewage has developed rapidly. The waste gas generated in the sewage pool has become a focus of attention in my country. The existing sewage sealing cover plates are mostly made of glass fiber reinforced plastics. Considering the comprehensive aspects, the glass fiber reinforced plastic cover plate occupies the first place with absolute advantage. Although it is not as strong as some metal covers, its anti-corrosion performance is far beyond the reach of metal covers. In terms of bearing capacity, it is far better than wooden covers and plastic covers, and its designability and safety performance are far better than the above-mentioned covers. In some glass fiber reinforced plastic covers, three cloths and five oils technology will be used for sealing, that is, the prepared resin is applied to the joints through a hair roller brush, and then the outer layer is coated with glass fiber adhesive, and then the resin is continued to be applied on the surface. The last layer is coated with glass fiber cloth, and finally the hair roller brush with resin is used to apply it evenly, and the operation is repeated in sequence.

[0003] Most of the existing glass cover panels are arched and semicircular. When installing the semicircular cover panel, the entire assembled cover panel is lifted by lifting equipment, and the construction personnel perform on-site positioning and adjustment, and then fix it by technology. However, the on-site environment is mostly sewage wells, and the area of ​​some areas is not enough to allow some lifting equipment to enter the site to install the cover panel, which reduces the practicability of the cover panel installation.

[0034] like Figure 1 to Figure 4As shown, the contact portion between the flow fan 22 and the limit ring 21 is installed with a sealing ring for increasing the sealing of the top cover, and the connection between the first sealing plate 2 and the third sealing plate 4 can be sealed by the "three cloths and five oils" technology. FRP antistatic agent is added to the slurry for making the first sealing plate 2, the third sealing plate 4 and each second sealing plate 3 to eliminate the influence of static electricity.

[0035] The working principle of this embodiment is:

[0036] When installing at the designated position, the first step is to install each insulation board 1, and the second step is for workers to carry and install the first sealing plate 2, and bolt it at the bottom and side to limit the position, and then install the third sealing plate 4 on one side of the first sealing plate 2 according to the limiting ring 21, and then install the remaining second sealing plates 3 in turn, and determine the number of the second sealing plates 3 according to the quality of the sealing plates to facilitate the workers to carry, and the sealing plates are mutually engaged and aligned by the positioning grooves 26 on the sealing plates and the first positioning blocks 29 on the adjacent sealing plates. After all the sealing plates are installed and connected, the three-cloth-five-oil technology is used to seal the gap between the first sealing plate 2 and the third sealing plate 4, and the flow fan 22 is installed on the limiting ring 21 to stir the air above the limiting ring 21 and increase the fluidity of the gas. According to the installation position, an iron chain with a length that can contact the ground is put on the discharge hook 27 to guide the static electricity generated by the top cover to the bottom.
