Description

Technical Field

[0001] This application relates to the technical field of silt removal equipment, and specifically relates to a silt removal equipment for a water conservancy pumping station. Background Technique

[0002] As one of the important facilities for water resource allocation, the pumping station needs to maintain an efficient and stable operating state to meet the water supply demand. Over time, impurities such as sediment and suspended matter will be carried in the water body of the pumping station, and these impurities will gradually deposit inside the pumping station, forming siltation. If not cleaned in time, the siltation will block the pipes, valves and pump bodies of the pumping station, affecting the normal operation and pumping efficiency of the pumping station.

[0003] Patent No. CN 221372322 U discloses a silt removal equipment for a water conservancy pumping station. When the equipment main body extracts silt, the silt will pass through the mud suction pipe. When large impurities in the silt pass through the fitting ring, they will be filtered by the filter screen. When too many impurities accumulate, the user closes the equipment main body and pulls the fitting ring outwards by grasping the handle, then the fitting ring can be pulled out of the mud suction pipe and cleaned. The filter screen facilitates the user to clean the impurities and avoid the accumulation of impurities blocking the mud suction pipe.

[0004] However, in use, it has the following defects:

[0005] Although the fitting ring and the filter screen are used to intercept large impurities and can be pulled out for cleaning, after the filter screen intercepts large impurities, it will affect the smoothness of the mud suction pipe. It is rather troublesome for the user to clean the fitting ring regularly, which affects the silt removal efficiency. Content of the Utility Model

[0006] The purpose of this application is to provide a silt removal equipment for a water conservancy pumping station, which solves the problem that after the filter screen intercepts large impurities, it will affect the smoothness of the mud suction pipe, and it is rather troublesome for the user to clean the fitting ring regularly, which affects the silt removal efficiency as mentioned in the background technique.

[0007] To achieve the above purpose, this application provides the following technical solution: A silt removal equipment for a water conservancy pumping station, including an equipment main body, a fixed ring, a fixed cylinder and a support frame. The bottom of the equipment main body is communicated with a mud suction pipe. The other end opening of the mud suction pipe is fixedly connected with a fixed ring. A ring groove is opened on the side wall of the fixed cylinder. The top and bottom of the fixed cylinder are respectively penetrated and provided with a top groove and a bottom groove. The top surface of the fixed cylinder at the opening above the top groove is fixedly connected with an installation platform. The top of the installation platform is fixedly connected with an electric push rod. The bottom telescopic end of the electric push rod penetrates through the installation platform and is fixedly connected with a push plate. The bottom surface of the fixed cylinder at the bottom below the bottom groove is fixedly connected with a collection groove, and the collection groove is communicated with the bottom groove; the edge of the surface of the fixed ring facing the fixed cylinder is rotatably connected with a rotating shaft. Both the left and right surfaces of the rotating shaft are fixedly connected with support frames, and the support frames are attached to the surface of the fixed ring.

[0008] In this technical solution, after the electric push rod is started, it extends downward, driving the lower push plate to move from the top groove to the bottom groove, pushing the mud block into the collection groove, then lifting it by hand and continuing to push downward, so as to continuously push the mud block, thus minimizing the obstruction and blockage of the mud block to the filter screen and reducing the number of manual disassembly and cleaning operations, ensuring the normal silt suction efficiency; when the filter screen needs to be replaced, the fixed cylinder is temporarily removed, and then the rotating shaft is rotated to drive the support frame and the filter screen to rotate, so that the new one rotates in and the old one rotates out, and then the fixed cylinder is reinstalled, and the support frame is snapped into the annular groove to complete the fixation, thus completing the rapid replacement of the filter screen, improving the silt discharge efficiency of the device, and the rotated-out support frame and filter screen can be cleaned later.

[0009] Preferably, six screw rods are fixedly connected to the surface of the fixed cylinder on the outer side of the annular groove in a circumferential array, and the other ends of the screw rods horizontally penetrate through the surface of the fixed ring.

[0010] Preferably, a side groove is formed in the surface of the fixed cylinder on one side of the annular groove, and the side groove is communicated with the annular groove.

[0011] Preferably, the top groove and the bottom groove have the same size, and the outer side wall of the push plate fits with the inner side wall of the top groove.

[0012] Preferably, a groove door is movably connected to the side wall of the collection groove.

[0013] Preferably, a sealing gasket is fixedly connected to the inner side wall of the annular groove.

[0014] Compared with the prior art, the beneficial effects of the present application are as follows:

[0015] 1. Through the top groove, bottom groove, push plate and collection groove of the present application, the blockage of the filter screen can be reduced. After the electric push rod is started, it extends downward, driving the lower push plate to move from the top groove to the bottom groove, pushing the mud block into the collection groove, then lifting it by hand and continuing to push downward, so as to continuously push the mud block, thus minimizing the obstruction and blockage of the mud block to the filter screen and reducing the number of manual disassembly and cleaning operations, ensuring the normal silt suction efficiency.

[0016] 2. Through the rotating shaft, support frame and annular groove of the present application, the filter screen can be quickly replaced. When the filter screen needs to be replaced, the fixed cylinder is temporarily removed, and then the rotating shaft is rotated to drive the support frame and the filter screen to rotate, so that the new one rotates in and the old one rotates out, and then the fixed cylinder is reinstalled, and the support frame is snapped into the annular groove to complete the fixation, thus completing the rapid replacement of the filter screen, improving the silt discharge efficiency of the device.

Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the following will be further elaborated in combination with specific embodiments.

[0023] A silt removal device for a water conservancy pumping station, referring to Figures 1 to 3 , includes an equipment main body 1, a fixed ring 3, a fixed cylinder 6 and a support frame 5. The bottom of the equipment main body 1 is communicated with a sludge suction pipe 2. The other end opening of the sludge suction pipe 2 is fixedly connected with a fixed ring 3. A ring groove 14 is opened on the side wall of the fixed cylinder 6. The top and bottom of the fixed cylinder 6 are respectively penetrated with a top groove 9 and a bottom groove 11. The top surface of the fixed cylinder 6 at the upper opening of the top groove 9 is fixedly connected with an installation platform 7. The top of the installation platform 7 is fixedly connected with an electric push rod 8. The bottom telescopic end of the electric push rod 8 penetrates through the installation platform 7 and is fixedly connected with a push plate 10. The bottom surface of the fixed cylinder 6 at the lower part of the bottom groove 11 is fixedly connected with a collection groove 12, and the collection groove 12 is communicated with the bottom groove 11. When the electric push rod 8 is started, the push plate 10 below is driven to move from the top groove 9 to the bottom groove 11, pushing the mud blocks into the collection groove 12, thereby minimizing the blockage of the filter screen by the mud blocks and reducing the number of manual disassembly and cleaning times; the surface edge of the fixed ring 3 facing the fixed cylinder 6 is rotatably connected with a rotating shaft 4. Support frames 5 are fixedly connected to both the left and right surfaces of the rotating shaft 4. The support frames 5 are attached to the surface of the fixed ring 3, and sealing strips are attached to both the front and back surfaces of the support frames 5, which can ensure sealing when the fixed cylinder 6 and the fixed ring 3 are attached. Rotating the rotating shaft 4 drives the support frames 5 and the filter screen to rotate, allowing the new ones to turn in and the old ones to turn out, and then reinstalling the fixed cylinder 6 so that the support frames 5 are snapped into the ring groove 14 to complete the fixation, thereby completing the rapid replacement of the filter screen and improving the silt removal efficiency of the device.

[0024] Specifically, as Figure 1 andFigure 2 As shown in the figure, six screw rods 13 are fixedly connected to the surface of the fixed cylinder 6 outside the annular groove 14 in a circumferential array. The other end of the screw rod 13 horizontally penetrates through the surface of the fixed ring 3. When the fixed ring 3 and the fixed cylinder 6 are in contact, the screw rod 13 is screwed into the nut to complete the fixation, ensuring that it will not fall off during the silt removal process.

[0025] It is worth noting that, as Figure 2 shown in the figure, a side groove 141 is formed on the surface of the fixed cylinder 6 on one side of the annular groove 14. The side groove 141 communicates with the annular groove 14. The side groove 141 is mainly used to facilitate the insertion of the rotating shaft 4 when the fixed ring 3 and the fixed cylinder 6 are in contact, so that the fixed ring 3 and the fixed groove can be properly fitted.

[0026] It is worth noting that, as Figure 3 shown in the figure, the top groove 9 and the bottom groove 11 have the same size, and the outer side wall of the push plate 10 is in contact with the inner side wall of the top groove 9. When not in use, the push plate 10 is located inside the top groove 9. At this time, the silt removal proceeds normally. Only when it is necessary to clear the blockage of larger mud blocks, it will be lifted and pushed under the drive of the electric push rod 8. During the silt removal process, due to the continuous suction of the sludge pump, generally, smaller mud blocks will directly pass through the filter screen under the action of the suction force and will not fall into the bottom groove 11, so that the collection frame is mainly used to collect larger mud blocks.

[0027] It is worth noting that, as Figure 1 shown in the figure, a slot door 121 is movably connected to the side wall of the collection groove 12. When the collection groove 12 is almost full, the slot door 121 can be opened to clean the collection groove 12.

[0028] It is worth noting that, as Figure 3 shown in the figure, a sealing gasket 15 is fixedly connected to the inner side wall of the annular groove 14. After the support frame 5 is inserted into the annular groove 14, the sealing gasket 15 can fill the gap between the annular groove 14 and the support frame 5 to ensure sealing.

[0029] During actual use, the sludge pump of the device main body 1 starts to pump the sludge. When passing through the filter screen of the support frame 5, smaller sludge blocks pass through, while larger sludge blocks are intercepted. At this time, through the top groove 9, bottom groove 11, push plate 10 and collection groove 12, the clogging of the filter screen can be reduced. After the electric push rod 8 starts, it extends downward, driving the lower push plate 10 to move from the top groove 9 to the bottom groove 11, pushing the sludge blocks into the collection groove 12, then lifting it by hand and continuing to push downward, so as to continuously push the sludge blocks, thus minimizing the obstruction and clogging of the sludge blocks to the filter screen and reducing the number of manual disassembly and cleaning times, ensuring the normal silt suction efficiency. At the same time, through the rotating shaft 4, support frame 5 and annular groove, the filter screen can be quickly replaced. When the filter screen needs to be replaced, the fixed cylinder 6 is temporarily removed, then the rotating shaft 4 is rotated to drive the support frame 5 and the filter screen to rotate, so that the new one rotates in and the old one rotates out, and then the fixed cylinder 6 is reinstalled to make the support frame 5 snap into the ring groove 14 to complete the fixation, thus completing the quick replacement of the filter screen and improving the silt discharge efficiency of the device. Then, the removed support frame 5 and filter screen can be cleaned later.
