Description

Technical Field

[0001] The utility model relates to the technical field of sewage interception in pump stations, and particularly relates to a sewage interception device for a pump station. Background Art

[0002] Integrated pump stations are generally installed on riverbeds. Different from traditional pump stations, integrated pump stations do not require manual on-site monitoring during operation. Instead, only the built-in intelligent control system of the equipment needs to be set up. Since there are many impurities such as silt in the river, after the sewage enters the pump station, the existing integrated pump stations usually use a sewage interception net to intercept the massive soil or floating objects in the sewage to prevent the massive soil or floating objects from blocking the water pumps in the pump station.

[0003] However, after the existing massive soil or floating objects are intercepted, they usually need to be regularly cleaned manually. Since the interception device is built into the pump station, it is difficult to clean manually. Often, due to untimely cleaning, the entire interception device is blocked, affecting the inflow of sewage into the pump station.

[0004] The above content is only used to assist in understanding the technical solution of the present invention, and does not represent an admission that the above content is the closest prior art. Content of the Utility Model

[0005] The purpose of the utility model is to provide a sewage interception device for a pump station, so as to solve the problem that after the existing massive soil or floating objects are intercepted, they usually need to be regularly cleaned manually. Since the interception device is built into the pump station, it is difficult to clean manually. Often, due to untimely cleaning, the entire interception device is blocked, affecting the inflow of sewage into the pump station as mentioned in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A sewage interception device for a pump station, including a pump station body, and a water inlet pipe is arranged on one side of the pump station body. It further includes:

[0008] An interception unit, which is arranged inside the pump station body and is connected to the water outlet end of the water inlet pipe, and is used for intercepting the massive soil or floating objects contained in the sewage entering from the water inlet pipe;

[0009] A sewage cleaning unit, including an extrusion assembly arranged above the interception unit for extruding the massive soil or floating objects intercepted by the interception unit, and a crushing assembly arranged below the interception unit for cooperating with the extrusion assembly to crush and discharge the massive soil or floating objects.

[0010] Further, the interception unit includes:

[0011] A support, which is fixedly connected inside the pump station body and is located below the water inlet pipe;

[0012] The side retaining net is fixedly connected to the upper end of the support, and the side retaining net is arranged in a three-sided shape;

[0013] The mounting plate is fixedly connected to one end of the side retaining net and the water inlet end of the water inlet pipe at the other end. The mounting plate and the side retaining net enclose a square shape for strengthening the side retaining net.

[0014] Furthermore, the extrusion assembly includes:

[0015] The top plate is fixedly connected to the upper ends of the mounting plate and the side retaining net;

[0016] The bracket is fixedly connected to the middle of the upper end of the top plate;

[0017] The electric cylinder is installed on one side of the bracket;

[0018] The lower pressing plate is arranged to slide up and down inside the side retaining net. The upper end of the lower pressing plate is fixedly connected to the driving end of the electric cylinder, and is used to push out the blocky soil intercepted by the side retaining net from the crushing assembly.

[0019] Furthermore, multiple groups of extrusion blocks are evenly distributed at the lower end of the lower pressing plate, and are used to cut and push out the floating objects intercepted by the side retaining net from the crushing assembly.

[0020] Furthermore, the crushing assembly includes:

[0021] The bottom plate is fixedly connected to the upper end of the support;

[0022] The extrusion holes are evenly distributed at the upper end of the bottom plate and correspond to the extrusion blocks one by one, and are used to cooperate with the extrusion blocks to cut the intercepted floating objects.

[0023] Furthermore, through holes corresponding to the extrusion holes one by one are penetrated inside the support;

[0024] The height of the extrusion block is greater than the sum of the depths of the extrusion hole and the through hole;

[0025] The length and width of the extrusion block are both smaller than the length and width of the extrusion hole and the through hole, and are used to enable the crushed blocky soil and floating objects to be discharged along the gaps between the extrusion block and the extrusion hole and the through hole when the lower pressing plate presses the blocky soil and floating objects piled up at the upper end of the bottom plate.

[0026] Compared with the prior art, the beneficial effects of the present utility model are:

[0027] 1. The utility model drives the lower pressing plate to move downward along the inner side of the side retaining net through an electric cylinder. The lower pressing plate drives the extrusion block to move downward and insert into the extrusion hole and the through hole in sequence, so that the massive soil piled on the bottom plate is crushed by the extrusion block and discharged along the gap between the extrusion block and the extrusion hole and the through hole. The floating objects are shredded under the shearing force between the extrusion block and the extrusion hole, and the shredded floating objects are discharged from the interception unit along the extrusion hole and the through hole. Subsequently, the electric cylinder drives the extrusion block to move upward to the initial position through the lower pressing plate, and the remaining crushed residues are further carried out of the interception unit by the sewage entering from the water inlet pipe, thus avoiding the blockage of the water pump in the pumping station by massive soil or floating objects and eliminating the need for manual cleaning of the interception device.

[0028] 2. When the electric cylinder drives the lower pressing plate to move downward, the lower pressing plate moves along the inner side of the side retaining net, so that the impurities adhered to the inner side of the side retaining net are scraped off and fall on the bottom plate, avoiding the blockage of the side retaining net by impurities and affecting the entry of sewage into the pumping station body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1-6 , the present invention provides a technical solution:

[0038] A sewage interception device for a pumping station, including a pumping station body 100, and a water inlet pipe 101 is provided on one side of the pumping station body 100. It further includes:

[0039] An interception unit 1, which is arranged inside the pumping station body 100 and is connected to the water outlet end of the water inlet pipe 101, and is used to intercept the blocky soil or floating objects contained in the sewage entering from the water inlet pipe 101;

[0040] A sewage cleaning unit 2, including an extrusion assembly 21 arranged above the interception unit 1 for extruding the blocky soil or floating objects intercepted by the interception unit 1, and a crushing assembly 22 arranged below the interception unit 1 for cooperating with the extrusion assembly 21 to crush and discharge the blocky soil or floating objects.

[0041] As an improvement, as Figure 2 shown, the interception unit 1 includes:

[0042] A support 11, which is fixedly connected inside the pumping station body 100 and is located below the water inlet pipe 101;

[0043] A side retaining net 12, which is fixedly connected to the upper end of the support 11, and the side retaining net 12 is arranged in a three-sided shape;

[0044] A mounting plate 13, one end of which is fixedly connected to the side retaining net 12, and the other end is fixedly connected to the water inlet end of the water inlet pipe 101. The mounting plate 13 and the side retaining net 12 enclose a square shape for strengthening the side retaining net 12.

[0045] Furthermore, as Figure 2 , Figure 6 shown, the extrusion assembly 21 includes:

[0046] A top plate 211, which is fixedly connected to the upper ends of the mounting plate 13 and the side retaining net 12;

[0047] A bracket 212, which is fixedly connected to the middle of the upper end of the top plate 211;

[0048] An electric cylinder 213, which is installed on one side of the bracket 212;

[0049] The lower pressing plate 214 is arranged inside the side retaining net 12 and can slide up and down. The upper end of the lower pressing plate 214 is fixedly connected to the driving end of the electric cylinder 213, and is used to push out the massive soil intercepted by the side retaining net 12 from the crushing assembly 22.

[0050] A guiding hole 2111 for passing through the driving end of the electric cylinder 213 is arranged inside the top plate 211.

[0051] Furthermore, as Figure 2 , Figure 6 shown, multiple groups of extrusion blocks 215 are equally spaced at the lower end of the lower pressing plate 214, and are used to cut and push out the floating objects intercepted by the side retaining net 12 from the crushing assembly 22.

[0052] Among them, as Figures 2-4 shown, the crushing assembly 22 includes:

[0053] A bottom plate 221, fixedly connected to the upper end of the support 11;

[0054] Extrusion holes 222 are equally spaced at the upper end of the bottom plate 221 and correspond to the extrusion blocks 215 one by one, and are used to cooperate with the extrusion blocks 215 to cut the intercepted floating objects.

[0055] In addition, as Figures 4-5 shown, through holes 111 corresponding to the extrusion holes 222 one by one are arranged through the inside of the support 11;

[0056] The height of the extrusion block 215 is greater than the sum of the depths of the extrusion hole 222 and the through hole 111;

[0057] The length and width of the extrusion block 215 are both smaller than the length and width of the extrusion hole 222 and the through hole 111, and are used to enable the crushed massive soil and floating objects to be discharged along the gaps between the extrusion block 215 and the extrusion hole 222 and the through hole 111 when the lower pressing plate 214 presses the massive soil and floating objects piled up at the upper end of the bottom plate 221.

[0058] It should be noted that: as Figures 1-3 shown, in the specific implementation process of the present utility model, when sewage enters the pump station body 100 through the water inlet pipe 101, in order to prevent the water inlet of the water pump in the pump station body 100 from being blocked, the side retaining net 12 intercepts the floating objects and massive soil in the sewage, and the intercepted floating objects and massive soil are piled up at the upper end of the bottom plate 221, thereby avoiding the water pump in the pump station body 100 from being blocked by the massive soil and floating objects;

[0059] As Figures 3-6As shown, when a certain thickness of block soil and floating objects are accumulated on the bottom plate 221 and need to be cleaned, the electric cylinder 213 is started, and the electric cylinder 213 drives the lower pressure plate 214 to push downward along the inner side of the side screen 12, and the lower pressure plate 214 drives the extrusion block 215 to move downward until it is inserted into the extrusion hole 222 and the through hole 111 in sequence, so that the block soil accumulated on the bottom plate 221 is crushed by the extrusion block 215 and discharged along the gap between the extrusion block 215 and the extrusion hole 222 and the through hole 111, and the floating objects are squeezed out. The floating objects cut into small pieces are cut into pieces by the shear force between the block 215 and the extrusion hole 222, and are discharged from the interception unit 1 along the extrusion hole 222 and the through hole 111. Subsequently, the electric cylinder 213 drives the extrusion block 215 to move upward to the initial position through the lower pressure plate 214, and the crushed residual debris is further taken out of the interception unit 1 by the sewage entering from the water inlet pipe 101, thereby preventing the block mud or floating objects from clogging the water pump in the pump station and eliminating the need for manual cleaning of the interception device.

[0060] like Figure 2 As shown, when the electric cylinder 213 drives the lower pressure plate 214 to move downward, the lower pressure plate 214 moves along the inner side of the side screen 12, so that impurities adhering to the inner side of the side screen 12 are scraped off and fall onto the bottom plate 221, thereby preventing the side screen 12 from being blocked by impurities and affecting the entry of sewage into the pump station body 100.

[0061] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
