SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides a pump station catch basin's vacuum back flush structure through structural negative pressure diversion room of addding of traditional pump station, utilizes integration vacuum diversion flushing device, realizes the back flush to the pump station catch basin, has reduced and has washd hidden danger and cost expenditure.
In order to achieve the above object, the technical solution of the present invention is specifically as follows:
a vacuum backwashing structure of a pump station water collecting tank is characterized in that a grid sewage removal machine and a drainage device are arranged in the water collecting tank, the water collecting tank is connected with a water inlet pipe and a water outlet pipe, a negative pressure diversion chamber is arranged on the water outlet side of the water collecting tank, integrated vacuum diversion flushing equipment is installed at the top of the negative pressure diversion chamber, and through holes are formed in the bottoms of the negative pressure diversion chamber and the water collecting tank; and a lock well is arranged between the water collecting tank and the water inlet pipe, and the lock well is communicated with the water collecting tank through a gate.
Further, in the above technical solution, the water collecting tank includes a plurality of sub-water collecting tanks, and each sub-water collecting tank corresponds to one negative pressure diversion chamber.
Further, in the above technical scheme, the vacuum back-washing structure further comprises a water outlet tank, and the water outlet tank is arranged above the water collecting tank or above the negative pressure diversion chamber.
Further, in the above technical scheme, a guide slope for pumping station water intake is arranged in the bottom of the water collecting tank.
The utility model has the advantages that: when the structure is used for dredging the bottom of the water collecting tank, only the water collecting tank needs to be emptied, and because the negative pressure diversion chamber and the water collecting tank have higher liquid level difference, water flows out through the through hole at the bottom of the negative pressure diversion chamber without dead angles to wash out the water collecting tank of the pump station, and strong washing flow reversely washes out the bottom feet of the grid installation, thereby effectively relieving the phenomena of chain breaking and chain falling caused by foreign matter blockage in grid operation, prolonging the service life of equipment and saving the maintenance cost. The water collecting tank is divided into a plurality of sub-set water tanks, so that the continuous operation of a pump station can be ensured, and the cutoff is avoided.

FIG. 2 is a sectional view taken along the plane C-C;
fig. 3 is a schematic view of a vacuum backwashing structure of the sump of the rainwater pumping station in embodiment 2.
Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the embodiments and the accompanying drawings.
Example 1
A vacuum back-flushing structure of a water collecting tank of a sewage pump station is shown in figures 1-2 and comprises a water collecting tank 1 and a negative pressure diversion chamber 2, wherein the negative pressure diversion chamber 2 is arranged on the water outlet side of the water collecting tank 1 of the pump station and can be synchronously and integrally constructed with the main structure of the pump station; the top of the negative pressure diversion chamber 2 is provided with an integrated vacuum diversion flushing device 3, and the bottom of the negative pressure diversion chamber 2 is provided with a through hole communicated with the water collecting tank 1.
One end of the pump station water collecting tank 1, which is far away from the negative pressure diversion chamber 2, is connected with the water inlet pipeline 5, a lock well 13 is arranged between the water collecting tank 1 and the water inlet pipeline, and a gate is arranged on the tank wall between the lock well 13 and the water collecting tank 1. The water collecting tank 1 is also internally provided with a grid sewage removing machine 8, a drainage device 12 and a water outlet pipeline 6, the water outlet tank 9 of the structure is arranged above the negative pressure diversion chamber and close to the side surface of the water collecting tank, and the water outlet ends of the water outlet pipeline 6 and the drainage device 12 are connected in the water outlet tank 9 to realize drainage in the water collecting tank 1. A guide slope 4 for water inlet of the pump station is arranged in the bottom of the water collecting tank.
The washing process of the structure is as follows: before the water diversion work of the integrated vacuum water diversion flushing equipment 3 is started, the water collecting pool of the pump station and the negative pressure water diversion chamber keep the same water level; during the diversion work starting process of the integrated vacuum diversion flushing equipment, a set high water level can be formed and maintained in the negative pressure diversion chamber, the pump station collecting basin needs to be cleaned of bottom sediment, only the collecting basin needs to be emptied, the negative pressure diversion chamber and the pump station collecting basin reach a set liquid level difference value at the moment, the integrated vacuum diversion flushing equipment can send a flushing instruction, a high water head is discharged from the negative pressure diversion chamber through a bottom hole and has no dead angle to flush the pump station collecting basin, the strong flushing flow can utilize the slope guide of pump station inlet water to quickly flow back, and the bottom of the pump station collecting basin is subjected to secondary washing in the reciprocating process of water flow; at the moment, the emptying pump in the automatic operation state is started to operate, the mud-water mixture is discharged out of the pool together, and the current round of flushing is finished.
