Detailed Implementation

[0040] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0041] As shown in Figures 1-7, the purpose of this utility model is to provide a sewage lifting pump station that allows for easy adjustment of the installation hole position, so that on-site installation does not require finding a new installation position for drilling or re-drilling.

[0043] When using this utility model, it can be installed underground using the detachable base connector, and fixed with anchor bolts; or it can be installed by sinking the bottom using the anti-buoyancy crossbar, thus achieving the purpose of multiple installation methods; the holes on the base connector for installing anchor bolts are designed with multiple specifications, which makes it convenient to select base connectors with different hole diameters for different installation positions, and to select anchor bolts with different diameters for different installation positions.

[0044] The above solutions enable the pump station provided by this utility model to achieve both dry installation and underground installation. When dry installation is performed, it is directly fixed with anchor bolts or expansion bolts. When underground installation is performed, the bottom of the water collection tank 1 has an anti-buoyancy structure design, that is, the bottom of the water collection tank 1 has a round hole (anti-buoyancy hole 21), which is anti-buoyancy by inserting anti-buoyancy crossbars.

[0045] In one embodiment, as shown in Figures 1-7, the purpose of this utility model for a sewage lifting pump station is to: design the configuration of one or more pumps / collection tanks according to the water storage capacity, so that when multiple pumps work in their respective collection tanks, their working efficiency can be improved and the tank volume can be increased (i.e., the water output can be increased); when multiple pumps work in combination with their corresponding collection tanks in a standby mode, the service life of the product can be improved and its failure rate reduced; or in other words, when one pump fails, it will not affect the normal operation of the pump station.

[0046] Specifically, it includes: a water pump 3, used to empty the sewage in the water collection tank 1, which is installed in the water collection tank 1; the water collection tank 1 is designed as a single or multiple volume, and the volume of the water collection tank 1 and the number of water pumps 3 are matched one by one to form a complete set of components.

[0047] When there are two sets of water collection tanks 1, the side walls of the water collection tanks 1 are provided with guide grooves 20 at intervals, and the guide grooves 20 are located between the two water inlets 18 on the side walls of the water collection tanks 1.

[0048] The water collection tank 1 is provided with a water inlet, which may be one or more, located at the top or side wall of the water collection tank 1. The top of the water collection tank 1 has an opening, which is sealed by a cover 7, wherein the water collection tank 1 and the cover 7 are sealed by a rubber ring. In this embodiment, when the water collection tank 1 has multiple volumes, the built-in water pumps can operate individually or simultaneously to achieve the purpose of sewage discharge. When the water collection tank 1 has multiple volumes, the multiple water collection tanks can be interconnected.

[0049] For example, when the water collection tank 1 is set to two sets: adopting a double volume structure, the water collection tank 1 is designed to be two or more in parallel, so as to realize the one-in-one standby control of the water pump, extend the service life of the equipment, reduce the equipment failure rate, and improve the stability of the product.

[0050] As shown in Figure 7, when there are two sets of water collection tanks 1, the side walls of the water collection tanks 1 are provided with guide grooves 20 at intervals. The guide grooves 20 are located between the two water inlets 18 on the side walls of the water collection tanks 1. The guide grooves 20 are used to strengthen the connection between the two water collection tanks 1, and at the same time facilitate the product size to increase without deformation during the molding process.

[0051] The opening between the cover 7 and the water collection tank 1 is detachably connected by threads. Furthermore, a rubber ring for sealing is provided between the cover 7 and the water collection tank 1 to seal the gap between them and prevent water seepage or leakage.

[0052] In one embodiment, as shown in Figures 1-7, the purpose of this utility model for a sewage lifting pump station is as follows: when the outlet pipe is working, water flows out through the inner wall of the pipe; simultaneously, under the action of pressure and gravity, the water also flows out through the backwash hole into the collection tank, thereby achieving the purpose of backwashing the inner wall of the collection tank; when the water volume in the collection tank is small, the water flowing out of the backwash hole can also be used to flush the inner wall of the collection tank, reducing the amount of sludge residue in the collection tank, thereby increasing the tank volume of the lifting pump station, and reducing the pipe blockage caused by sludge residue and deposition, further reducing the possibility of pump station failure caused by sludge residue and deposition.

[0053] Specifically, the water outlet connection assembly 4 is connected to the water pump 3 at one end and the water outlet pipe 19 at the other end; wherein, the end of the water outlet pipe 19 away from the water outlet connection assembly 4 is connected to the check valve 10; the end of the water outlet pipe 19 near the water pump 3 is provided with a backwash hole 14. The water pump 3 is located inside the water collection tank 1; the water pump 3 is an N-type pump.

[0054] In this embodiment, a backwash hole 14 is provided on the outlet pipe 19 located in the water collection tank 1. The backwash hole 14 is one or more and is located on the side wall of the outlet pipe 19. When the outlet pipe 19 is working, water flows out through the inner wall of the pipe. At the same time, under the action of pressure and gravity, water also flows out through the backwash hole 14 into the water collection tank, thereby achieving the purpose of backwashing the inner wall of the water collection tank 1. When the water volume in the water collection tank 1 is small, the water flowing out of the backwash hole 14 can also be used to flush the inner wall of the water collection tank 1, reducing the amount of sludge residue in the water collection tank 1, thereby increasing the water tank volume of the booster pump station, and reducing the pipe blockage caused by sludge residue and deposition, further reducing the possibility of pump station failure caused by sludge residue and deposition.

[0055] The check valve 10 consists of a check valve disc and a check valve body, preventing sewage from the municipal sewage pipe from flowing back into the pumping station. The outlet connection assembly 4 is connected to the inside of the water collection tank 1 by bolts 5 and a gasket 6.

[0056] This invention incorporates a built-in N-type pump, whose impeller can be raised to handle larger objects. When a larger object enters the pump, the impeller rises due to the force generated by the object passing through. This helps prevent blockages within the pump, thus ensuring continuous and efficient pumping of wastewater.

[0057] In one embodiment, as shown in Figures 1-7, the present invention further includes: a controller 11 located outside the water collection tank 1, which is electrically connected to the water pump 3 and the level gauge via a wiring harness; the level gauge includes a level tube 2, which is connected to the water collection tank 1 via a sealing ring, and the level acquisition end of the level tube 2 is located inside the water collection tank 1; and a float device 8, one end of which is hinged to the top inside the water collection tank 1, and the other end of which floats on the water surface of the water collection tank 1, rising and falling with the water level inside the water collection tank 1.

[0058] In this embodiment, the controller 11 is the brain of the pump station, connected to the water pump 3 and the level gauge 2 via a wiring harness. It controls the start and stop of the water pump using a control board and can provide real-time feedback on the equipment status via WIFI, achieving remote monitoring. Specifically, the controller can connect to the Xylem AquaTalk cloud platform via WIFI, where the equipment will be properly monitored and fast service can be provided, achieving the purpose of remote monitoring. The water pump control and monitoring in this solution are existing technologies; for details, please refer to application numbers CN201220202941.X, CN202023337178.5, CN202221921349.5, and CN202222125604.1.

[0059] Compared to traditional pumping stations, the lifting pumping station in this invention features a sealed design. The complete seal of the sewage lifting pumping station prevents odor leakage, thus avoiding pollution of the surrounding environment, eliminating odors generated during sewage collection and pumping, and improving the working environment. The level gauge 2 is screwed tightly onto the collection tank 1 and sealed with a sealing ring to prevent odor leakage. A float is fixed inside the collection tank 1, and its movement is regulated by the liquid level inside the tank.

[0060] In one embodiment, as shown in Figures 1-7, the present invention further includes: a water inlet including a water inlet 18 and a rubber connector 12, wherein the water inlet 18 is located on the side wall or top of the water collection tank 1, and the rubber connector 12 is used to connect the water inlet and the sewage pipe; wherein the rubber connector 12 is fixedly connected to the sewage pipe by a clamp 13.

[0061] The top of the water collection tank 1 is provided with an exhaust rubber pipe 9 that communicates with the interior of the water collection tank 1. Two opposite side walls of the water collection tank 1 are provided with handle grooves 17.

[0062] In this embodiment, the water pump 3 is installed inside the water collection tank 1. When the water pump 3 malfunctions, the cover 7 can be unscrewed and the water pump 3 can be pulled out from inside the water collection tank 1, thereby achieving the purpose of disassembling, repairing or replacing the malfunctioning water pump 3.

[0063] The base connector 15 and the anchor bolt 16 cooperate with each other to install the water collection tank 1 on the workbench, thereby fixing the pump station.

[0064] In this embodiment, the exhaust rubber pipe 9 provided on the top surface can be a vent. The exhaust rubber pipe 9 is installed on the top of the water collection tank 1 using a clamp 13. It can also be used to balance the internal pressure of the water tank 1 and prevent the diffusion of harmful gases inside the water tank 1. The pipe diameter of the exhaust rubber pipe 9 is DN50.

[0065] In this embodiment, the water collection tank 1 is used to collect sewage and is made of polyethylene with a tank volume of 120L or 240L; the rubber connecting pipe 12 and the water inlet 18 have a diameter of DN100; by designing water inlets at different locations, it is used to meet drainage requirements in different directions.

[0066] One end of the rubber connector 12 is inserted into the interface of the pump station (such as the water inlet above the water collection tank 1), and the other end is inserted into the sewage pipe. The rubber connector is then secured to the pipe by the clamp 13 to prevent sewage leakage. The operation is simple.
