However, this structure has the following disadvantages:

[0003] 1. The position of the water inlet is fixed, and the direction and position of the water inlet are fixed during production. However, the application site and construction environment vary, and if the position and direction of the water inlet are not convenient for water inflow, additional connection pipeline space is required for the connection of the pipeline and the water inlet. In addition, the length of the pipeline needs to be increased, which makes the on-site construction more difficult and costly.

[0004] 2. Since the direction and position of the water inlet are fixed, for the method of adding a pipeline to connect the water inlet, the pipeline sends sewage from the water inlet into the tank. If the pipeline can be used as a pipe, it is not easy to block. If the pipeline is curved or has many turns, it is easy to block, and it is not very convenient to unblock. SUMMARY

[0023] The utility model is further described below in combination with the drawings and embodiments:

[0024] Embodiment one: refer to Figures 1-3 As shown in the figure, a kind of sewage lifting pump body, including body 1, chamber 2 is equipped in the body 1, the top of the body 1 is equipped with sewage outlet 3 with the chamber 2 intercommunication, every outer wall on the periphery of the body 1 is equipped with at least one convex convex part 4 respectively, the top surface of the body 1 is also equipped with at least one convex convex part 4;It is also equipped with at least one water inlet 5, each water inlet 5 is set on the outer surface of one of the convex parts 4 respectively, and the water inlet 5 is communicated with the chamber 2.

[0025] In the utility model, the body is made of PE material, which is convenient for on-site hole opening. In this embodiment, the body is a cube or a cuboid structure, and at least one convex part is provided on the front, rear, left and right side walls and top surface. The water inlet is set on the corresponding convex part. After the pump body is produced, no water inlet is set on it. During on-site construction, according to the best position of water inlet, a hole is directly drilled on the convex part of the corresponding side of the body and connected with the chamber, thereby forming the water inlet. Subsequently, water can be directly introduced from the water inlet. In this structure, the position of the water inlet can be adjusted according to different strip-shaped and construction environments on site, thereby improving the application range and reducing the construction difficulty. In the case of installing the body at the best position and in the smallest space, the water inlet can be set at the corresponding position. The setting of the water inlet connection pipeline can be shortened as much as possible, the pipeline cost is reduced, the construction cost is also reduced. The pipeline is shortened, the occurrence of blockage is reduced, and the subsequent maintenance difficulty is reduced. In addition, the size of the water inlet can be adjusted according to the actual situation.

[0026] Moreover, the convex part is provided, and the water inlet is set on the convex part, so that the strength of the body is not damaged, thereby ensuring the firmness and strength of the body during use.

[0027] The front side outer wall, the left side outer wall, the right side outer wall and the rear side outer wall of the body are respectively provided with at least two protrusions arranged at intervals, and the top surface of the body is provided with at least two protrusions arranged at intervals, and the protrusion arranged at the top of the body is away from the pollution discharge port. In this embodiment, two protrusions can be arranged on the corresponding side wall, or three protrusions can be arranged, and the protrusions are arranged at intervals, so that the position of the water inlet can be selected according to the construction environment and adjustment on site.

[0028] The end surface of the protrusion arranged on the outer wall of the body is perpendicular to the bottom surface of the body, and the end surface of the protrusion arranged on the top surface of the body is parallel to the bottom surface of the body. In this way, during the opening of the water inlet, a hole opening device or a corresponding device is generally used for opening, and the hole opening device is perpendicular to the end surface of the protrusion. Therefore, the end surface of the protrusion is perpendicular or parallel to the bottom surface of the body, so that the opened water inlet also maintains a corresponding parallel or perpendicular relationship with the water inlet position, facilitating the connection of the subsequent pipeline and the water inlet, so that the axis of the connection between the pipeline and the water inlet is parallel, the axis of the pipeline is perpendicular to the end surface of the protrusion, and subsequent sealing of the connection between the pipeline and the water inlet facilitates the sealing process, ensures the sealing effect, and prevents water leakage at the connection between the pipeline and the water inlet.

[0029] As shown in Figure 2 , 3 , the recess 6 is outwardly recessed towards the outside of the body, and the body at the outwardly recessed position constitutes a protrusion. In this way, the protrusion is conspicuous, facilitating subsequent positioning of the opening of the water inlet and ensuring the convenience of positioning. At the same time, the wall thickness at the outwardly recessed and recessed position can be greater than the wall thickness at other positions of the body. Subsequent opening of the water inlet will not affect the strength of the body, and after the water inlet is connected with the pipeline, the protrusion at the water inlet is not easily deformed or damaged.

[0030] As shown in Figure 2 , 3 , a plurality of reinforcing ribs 7 are arranged in the recess 6, and the end portions of the reinforcing ribs 7 are connected with the inner wall of the recess 6. The arrangement of the reinforcing ribs increases the strength of the protrusion, especially the protrusion after the opening of the water inlet. The reinforcing ribs can be used for reinforcement, so that the water inlet has stronger compression resistance and deformation resistance after being connected with the pipeline, has better strength, and has a longer service life.

[0031] At the same time, in this embodiment, a plurality of protrusions are arranged, so that at least one water inlet is opened. Of course, more water inlets can be opened according to actual conditions, and only one water inlet can be opened on each protrusion.

[0032] As shown in Figure 1 , the top of the body 1 is provided with an inspection opening 8, and the cover plate 9 is detachably mounted on the inspection opening 8.

[0033] The setting of the maintenance opening facilitates subsequent maintenance of the chamber, such as disassembly and maintenance, installation, etc.

[0034] The utility model discloses still provided a kind of sewage lifting device, including above-mentioned sewage lifting pump body, still including sewage lifting pump (sewage drainage pump figure is not shown) and drain pipe 10, the sewage lifting pump is set in the chamber 2, and the bottom of the sewage lifting pump is on the bottom surface of the chamber 2, the middle part of the drain pipe 10 is installed in the drain 3, the bottom of the drain pipe 10 is connected with the sewage lifting pump, and the drain pipe 10 and the connecting place of the drain 3 are sealingly connected;

[0035] Still be equipped with water inlet pipe (water inlet pipe figure is not shown), the water inlet pipe is connected with the water inlet, and the water inlet pipe and the water inlet are sealingly connected.

[0036] In the embodiment, the sewage lifting pump is arranged in the chamber, the sewage is sent into the chamber through the water inlet pipe and the water inlet, and then the sewage is discharged by the sewage lifting pump in the chamber. The sewage lifting pump is arranged in the chamber, which can ensure the sewage lifting effect and stability.
