Description

Technical Field

[0001] This utility model is a water conservancy anti-clogging drainage device, belonging to the field of water conservancy facilities. Background Technology

[0002] In water conservancy and drainage operations, water pumps are indispensable key equipment. The pump's inlet is connected to a suction pipe, one end of which extends into the water body to draw in the water that needs to be discharged. However, natural water bodies often contain various kinds of debris. To prevent this debris from entering the pump and causing blockages in the impeller chamber, thus affecting the pump's normal operation, a filter screen is usually installed on the inlet pipe. The filter screen effectively intercepts larger debris, preventing it from entering the impeller chamber. However, in practical applications, problems arise when the amount of debris in the water is large. Within a short time, a large amount of debris intercepted by the filter screen accumulates rapidly, significantly reducing the filter's effectiveness. To maintain filtration, frequent shutdowns for cleaning the filter screen are necessary. These frequent shutdowns for cleaning severely impact the overall efficiency of the drainage work and increase drainage costs. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hydraulic anti-clogging drainage device to solve the problems mentioned in the background technology. This utility model reduces the frequency of downtime for cleaning the filter screen and improves the overall drainage efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic anti-clogging drainage device, comprising a main inlet pipe, one end of which is open. Two sets of first butterfly valves are installed on the outer surface of the main inlet pipe. A check valve is installed at the end of the first butterfly valve opposite to the main inlet pipe. A water pump is provided on the side of the check valve opposite to the first butterfly valve. The inlet end of the water pump is connected to the check valve. A cylindrical body is installed at the open end of the main inlet pipe, and detachable... The cylinder has two covers, and a pipe connector for connecting a water pump is installed at the middle of the outer surface of the cylinder. An arc-shaped filter screen is provided between the two covers. The arc-shaped filter screen is inserted into the cylinder, with the open end of the arc-shaped filter screen facing the pipe connector. Multiple partition discs are evenly installed inside the arc-shaped filter screen. Sealing plugs are installed at both ends of the arc-shaped filter screen. The sealing plugs are slidably installed in the cylinder. A push rod is installed on the side of one of the sealing plugs facing away from the arc-shaped filter screen. The push rod is inserted into a cover through a connector.

[0005] Furthermore, the connector includes a rectangular sleeve, and a rectangular sleeve is installed at the center of the side of the cover facing away from the cylinder. The push rod has a rectangular cross-section and passes through the rectangular sleeve. A first pin hole is opened on one side of the rectangular sleeve, and a second pin hole that mates with the first pin hole is opened on one side of the push rod. A positioning pin is inserted in the channel formed by the first pin hole and the second pin hole.

[0006] Furthermore, a connector is installed at one end of the push rod, and the side of the push rod away from the connector is recessed to form a connector groove that mates with the connector. The connector on one push rod is inserted into the connector groove on another push rod. A countersunk hole communicating with the connector groove is opened on one side of the push rod, and a screw hole that mates with the countersunk hole is opened on the connector. An internal hexagon screw is inserted into the countersunk hole, and one end of the internal hexagon screw is threaded into the screw hole.

[0007] Furthermore, the connector and the push rod are integrally formed, and the cross-section of the connector and the cross-section of the insertion slot are both rectangular.

[0008] Furthermore, an end plate is provided between the arc-shaped filter screen and the sealing plug, the end plate is connected and fixed to the arc-shaped filter screen, and the sealing plug is glued to the end plate.

[0009] Furthermore, connecting rings are installed at both ends of the cylinder, and the connecting rings are connected to the cover by multiple sets of bolts. A sealing ring is provided between the connecting rings and the cover.

[0010] Furthermore, a second butterfly valve is installed at the outlet end of the water pump, and the upper end of the second butterfly valve is connected to a main outlet pipe through a branch pipe, one end of which is open.

[0011] Furthermore, a flow transmitter is installed on the outer surface of the main outlet pipe, and a pressure gauge is provided on one side of the flow transmitter, which is connected to the main outlet pipe.

[0012] The beneficial effects of this utility model are:

[0013] 1. Install an arc-shaped filter screen in the cylinder, and install multiple partition discs in the arc-shaped filter screen to separate the space. Make the space formed by two adjacent partition discs in the arc-shaped filter screen face the pipe joint. Then, when a lot of debris accumulates in a single space in the arc-shaped filter screen, use a push rod to push the arc-shaped filter screen so that another single space in the arc-shaped filter screen faces the pipe joint. And so on, thereby reducing the frequency of stopping to clean the filter screen and improving the overall drainage efficiency.

[0014] 2. Install the connector on one push rod into the slot on another push rod using an internal hex screw, and so on, to complete the assembly of multiple push rods. This way, when adjusting the position of the arc-shaped filter screen inside the cylinder, it is not necessary to make long push rods. You only need to increase the number of push rods one by one during adjustment, avoiding the situation where long parts of the push rods are exposed on the outside of the cylinder and occupy space.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figure 1This utility model provides a technical solution: a hydraulic anti-clogging drainage device, including an inlet main pipe 1, one end of which is open. Two sets of first butterfly valves 2 are installed on the outer surface of the inlet main pipe 1. A check valve 3 is installed on the end of the first butterfly valve 2 away from the inlet main pipe 1. A water pump 4 is provided on the side of the check valve 3 away from the first butterfly valve 2. The inlet end of the water pump 4 is connected to the check valve 3. A second butterfly valve 5 is installed on the outlet end of the water pump 4. The upper end of the second butterfly valve 5 is connected to an outlet main pipe 6 through a branch pipe 9. One end of the outlet main pipe 6 is open. A flow transmitter 7 is installed on the outer surface of the outlet main pipe 6. A pressure gauge 8 is provided on one side of the flow transmitter 7 and is connected to the outlet main pipe 6. The first butterfly valve 2 and the second butterfly valve 5 cooperate with each other to facilitate the alternating use of the two water pumps 4. The flow transmitter 7 and the pressure gauge 8 are installed on the outside of the outlet main pipe 6 to monitor the drainage flow and pressure in real time. Staff can use this data to understand the working status of the drainage device in a timely manner, so as to identify problems and make adjustments in time, ensuring the efficient operation of the drainage system.

[0024] See Figures 1-5A cylindrical body 10 is installed at the open end of the main water inlet pipe 1. Removable caps 14 are installed at both ends of the cylindrical body 10. Connecting rings 13 are installed at both ends of the cylindrical body 10, and the connecting rings 13 are connected to the caps 14 by multiple sets of bolts. A sealing ring 12 is provided between the connecting rings 13 and the caps 14 to improve the sealing performance between the caps 14 and the connecting rings 13. A pipe connector 11 for connecting a water pumping pipe is installed at the middle of the outer surface of the cylindrical body 10. An arc-shaped filter screen 22 is provided between the two caps 14, inserted inside the cylindrical body 10, with the open end of the arc-shaped filter screen 22 facing the pipe. The connector 11 and the arc-shaped filter screen 22 are equipped with multiple partition discs 25 evenly installed inside. Both ends of the arc-shaped filter screen 22 are fitted with sealing plugs 24 that slide within the cylinder 10. An end plate 23 is provided between the arc-shaped filter screen 22 and the sealing plugs 24, and the end plate 23 is fixedly connected to the arc-shaped filter screen 22. The sealing plugs 24 are glued to the end plate 23, increasing the connection range between the arc-shaped filter screen 22 and the sealing plugs 24. Multiple partition discs 25 are evenly installed inside the arc-shaped filter screen 22, dividing its internal space into multiple independent small spaces. The opening of each small space faces the pipe connector 11 connected to the water pump pipe. During drainage, when debris in the water flows through the pipe connector 11 into the arc-shaped filter screen 22, it is intercepted in each independent space. Over time, if a large amount of debris accumulates in a particular space, affecting its filtration efficiency, it is not necessary to immediately stop the machine to clean the arc-shaped filter screen 22. By operating the push rod 16, the arc-shaped filter screen 22 can be slid within the cylinder 10, moving another independent space with less debris and better filtration performance towards the pipe joint 11 for continued high-efficiency filtration. This process is repeated sequentially, continuously switching between effective filtration spaces, significantly extending the overall effective service life of the arc-shaped filter screen 22. This reduces the frequency of downtime for cleaning the arc-shaped filter screen 22 and improves the overall efficiency of drainage operations.

[0025] See Figures 1-5A push rod 16 is installed on the side of a sealing plug 24 facing away from the arc-shaped filter screen 22. A rectangular sleeve 20 is installed in the middle of the side of a cover 14 facing away from the cylinder 10. The push rod 16 has a rectangular cross-section and passes through the rectangular sleeve 20. A first pin hole 26 is opened on one side of the rectangular sleeve 20, and a second pin hole 17 is opened on one side of the push rod 16 to mate with the first pin hole 26. A positioning pin 15 is inserted into the channel formed by the first pin hole 26 and the second pin hole 17 to keep the relative position of the push rod 16 and the cover 14 unchanged. A connector 27 is installed on one end of the push rod 16. The connector 27 and the push rod 16 are integrally formed. The side of the push rod 16 away from the connector 27 is recessed to form a groove 18 that mates with the connector 27. Both the cross-section of the connector 27 and the cross-section of the groove 18 are rectangular. The connector 27 on one push rod 16 is inserted into the groove 18 on the other push rod 16. One side of the push rod 16 has a countersunk hole 19 communicating with the groove 18. The connector 27 has a screw hole 21 that mates with the countersunk hole 19. A hexagonal socket screw is inserted into the countersunk hole 19, with one end threaded into the screw hole 21. The connector 27 at one end of one push rod 16 is aligned with the groove 18 on the other push rod 16, inserted, and then secured by screwing the hexagonal socket screw through the countersunk hole 19 on the side of the push rod 16 into the screw hole 21 of the connector 27, thus firmly connecting the two push rods 16. By repeating this operation—that is, installing each connector 27 into its corresponding slot 18 and securing it with hex screws—multiple push rods 16 can be assembled. When adjusting the position of the arc-shaped filter screen 22 within the cylinder 10, it is no longer necessary to specially manufacture a very long push rod 16. Instead, the operator can gradually increase the number of push rods 16 during the adjustment process according to actual needs. This avoids situations where a long portion of the push rod 16 is exposed on the outside of the cylinder 10, effectively saving space, making the spatial layout around the drainage device more rational, and reducing the risk of collision and damage that may result from exposed long push rods 16, thus improving the practicality and safety of the entire device.
