[0002] Sewage pumping station is an important part of sewage system. At present, the water inlet pipe of sewage pumping station is usually connected to the urban sewage collection system (such as underground sewage pipe network). Through the weight of sewage, sewage is gathered from various sources and guided to the entrance of pumping station into the pumping station, and there is a submersible sewage pump inside the pumping station to transport water to the sewage treatment plant. However, during the flood season, due to the excessive water flow, if there are problems such as insufficient number of pumps, sewage pumping station may have sewage backflow phenomenon, causing sewage inside the pumping station to flow out from the entrance of the pumping station again. Aiming at this problem, the utility model is improved. Utility Model Content

[0022] The following will be combined with the attached embodiment of the present utility model Figure 1-4 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] like Figures 1 to 4 As shown, the utility model discloses an anti-backflow intercepting sewage pump station, including a shell 1, on which is provided an inlet pipe 21, on one end of which is slidably connected a water baffle plate 22, which is used to block the port of the inlet pipe 21 for filling water into the shell 1, and at the same time, the water baffle plate 22 is provided with an elastic pushing mechanism for pushing the water baffle plate 22 toward the inlet pipe 21, and in addition, an anti-blocking mechanism is provided between the inlet pipe 21 and the water baffle plate 22, and the anti-blocking mechanism is used to enable the water baffle plate 22 to normally abut against the port of the inlet pipe 21.

[0025] The working principle of this structure is: when there is no water in the water inlet pipe 21 to flow into the shell 1 or the water pressure in the shell 1 is greater than that of the water inlet pipe 21, the elastic pushing mechanism is used to push the water baffle 22, so that the water baffle 22 blocks the water inlet pipe 21, thereby preventing the water in the shell 1 from flowing back into the water inlet pipe 21. At the same time, the anti-blocking mechanism is arranged between the water inlet pipe 21 and the water baffle 22 to enable some larger foreign objects to be crushed before they contact the water baffle 22, thereby preventing foreign objects from being stuck between the water baffle 22 and the water inlet pipe 21, so that the water baffle 22 can work normally to block the water inlet pipe 21.

[0026] The anti-blocking mechanism specifically includes a crushing grille 23, and the setting scheme of the crushing grille 23 is as follows: the crushing grille 23 includes a frame 231 and a rotating drum 232 installed in the frame 231, wherein the end edge of the water inlet pipe 21 is sealed and connected to the side wall of the frame 231, and the end of the crushing grille 23 facing away from the water inlet pipe 21 is provided with a water supply pipe 24, and a sealing mechanism is provided between the water supply pipe 24 and the crushing grille 23, and at the same time, a water baffle 22 is provided on the end of the water supply pipe 24 away from the crushing grille 23. In addition, supporting ribs for supporting the crushing grille 23 are provided on the shell 1. The main purpose of this structural setting is not only to enable the crushing grille 23 to crush foreign matter, Another point is to ensure that sewage can only flow into the shell 1 after passing through the water inlet pipe 21, the crushing grid 23 and the water supply pipe 24. Similarly, sewage backflow can only enter from the water supply pipe 24 and then flow back to the water inlet pipe 21. The advantage of this is that it can not only ensure that foreign matter is processed by the crushing grid 23 in the process of flowing with the water flow, but also the setting can bring the flow direction of the water together. No matter whether the sewage enters from the water inlet pipe 21 or the sewage is about to flow back, the sewage can concentrate the force on the water baffle 22, so that the water baffle 22 can effectively intercept the backflow sewage, and only the water supply pipe 24 needs to be blocked to achieve the effect of blocking the backflow.

[0027] The elastic push mechanism specifically includes a plurality of guide pillars 241 arranged along the circumferential direction and fixedly arranged on the outside of the water supply pipe 24 and an elastic pusher 242 sleeved on the guide pillars 241. In this structure, the end of one end of the guide pillar 241 is fixedly arranged on the outer wall of the water supply pipe 24, and the end of the other end extends from the water supply pipe 24 to the side of the water supply pipe 24 away from the crushing grid 23, and the water baffle 22 is slidably connected to the guide pillar 241 on one side of the water supply pipe 24. In this structure, the elastic pusher 242 abuts against the guide pillar 241 away from the crushing grid. The guide column 241 is provided between the end of the water baffle 22 and the side wall of the water supply pipe 24. When the water inlet pipe 21 stops discharging water or the water in the shell 1 starts to flow back, the elastic pusher 242 can push the water baffle 22 to block the water supply pipe 24. At the same time, the advantage of this structure is that the size of the water baffle 22 only needs to match the water supply pipe 24, and other variables will not affect the realization of the function of the water baffle 22. Regardless of the direction of the water supply pipe 24 and the direction of the water inlet pipe 21, the setting of the guide column 241 can make the sliding direction of the water baffle 22 easier to determine.

[0028] The outer edge of the water baffle 22 is sealed with a conical sleeve 221, and the inner wall of the conical sleeve 221 is used to abut against the end of the water supply pipe 24. This structure allows the water baffle 22 to adapt to a variety of water supply pipes 24 within a certain range.

[0029] A square connecting frame 25 is formed on the end of the water supply pipe 24 close to the crushing grille 23. One end of the square connecting frame 25 is hinged on the frame 231 and the other end is fixedly connected to the frame 231 by bolting. In addition, the sealing mechanism includes a sealing ring 251. The end of the square connecting frame 25 close to the frame 231 is used to set the sealing ring 251. This structure can facilitate the staff to check the inside of the crushing grille 23. When the staff needs to inspect the crushing grille 23, the bolts can be removed to separate the end of one side of the square connecting frame 25 from the crushing grille 23, so that the condition of the rotating drum 232 inside the crushing grille 23 can be seen.

[0030] In summary, the utility model drives the water baffle 22 to move through the concentrated effect of hydraulic force, and thereby intercepts the backflow of sewage, thereby achieving the effect of blocking backflow. It can effectively avoid the pollution of the surrounding soil, air, and groundwater environment caused by overflow of sewage in the sewage pumping station during flood season or other severe conditions, and is beneficial to protecting the ecological environment.
