Protection net needle prevents to float at bold floaters such as the plastics on sewage pond surface from stirring into stealthily dirty pump and causing water pump stop work under stealthily dirty pump suction effect, because the protection network all leaves certain spacing distance with stealthily dirty pump, between the inner wall in sewage pump room, even the protection network is partly stopped up, can not influence other meshes that sewage passes through the protection network and get into yet, compares current mouth of pipe at pressure waste pipe and removes and set up the grid, and the protecting effect is good, and can not cause the jam.
Preferably, the sewage pump room is internally provided with two submersible sewage pumps at intervals at the left and right, the two submersible sewage pumps are respectively provided with a pressure waste water pipe and a backwashing pipe and share the same main drainage pipe, the pressure waste water pipes of the two submersible sewage pumps are arranged on the same side, the ground pipe sections are in an L shape, the ground pipe sections of the two submersible sewage pumps are oppositely arranged on the same side far away from the pressure waste water pipes, the distribution of the ground pipe sections is optimized, the number of the inclined spray heads and the length of the ground pipe sections are simplified, the cost is further reduced, more importantly, the two L-shaped ground pipe sections are oppositely arranged on the same side far away from the pressure waste water pipes, and compared with the mode that the ground pipe sections surround the submersible sewage pumps, the impact force caused by the fact that the inclined spray heads are opposite.
Preferably, the side wall of the sewage pump room is sequentially provided with a low alarm water level, a pump stop water level, a 1# pump starting water level, a 2# pump starting water level and a high alarm water level from bottom to top. When the water level of the sewage pump room is at the corresponding water level, the control system is combined to alarm, stop and start the pump.
Preferably, the protection net is a rectangular net with four sides and formed by splicing, and the two submersible sewage pumps and the corresponding pressure wastewater pipes share the same protection net.
The utility model has the advantages that: in view of the fact that the existing backwash pipe cannot completely cover the bottom of the pool, the backwash reinforcing device can fully and completely stir mud at the bottom of the pool by surrounding the ground pipe section and the inclined spray heads which are paved at the periphery of the submersible sewage pump. The backwashing reinforcement device is additionally arranged on the basis of the existing backwashing pipe, so that the sludge prevention of the submersible sewage pump is realized together, the cost is low, the influence on the normal operation of a subway station caused by frequent maintenance can be avoided, the maintenance cost is saved, the service life of the submersible sewage pump is obviously prolonged, and the backwashing reinforcement device has wide popularization value.
