All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The high-modulus polypropylene prefabricated pump station top cover shown in fig. 1 and 2 comprises a top cover body 1, wherein a maintenance opening 11 is formed in the top cover body 1, and a cover plate 2 is arranged above the maintenance opening 11; the right side below the maintenance opening 11 is provided with the staircase 3, the left side below the maintenance opening 11 is provided with the first grille 4, and the first grille 4 is lower than the height of the top of the staircase 3. The first grille 4 provides a stepping platform for maintenance personnel, and is convenient for the maintenance personnel to get on or off the escalator. The top cover body 1 is provided with a vent (not shown), a vent pipe is arranged at the vent position, and an exhaust fan is arranged in the vent pipe so as to ventilate a pump station and avoid the harm to operators caused by toxic gas accumulation.
As shown in fig. 1 and 2, the top cover body 1 is made of high-modulus polypropylene, a maintenance opening 11 is formed in the middle of the top cover body 1, a connecting flange 12 is installed at the edge of the maintenance opening 11, two cover plates 2 are installed on the upper side of the connecting flange 12 through hinges, and the hinges are located on the left side and the right side of the maintenance opening 11. The cover plate 2 is made of embossed aluminum alloy plates, and a handle 21 is arranged on the cover plate 2, so that the cover plate 2 can be conveniently opened.
