Description

Technical Field

[0001] This utility model relates to the technical field of water flow channel dredging equipment, specifically a water flow channel dredging device. Background Technology

[0002] For flood control and drainage, surface water channels (such as vertical pipes under rain grates) are important drainage paths. The tops of these channels are usually equipped with filters to intercept large pollutants such as leaves and plastic bags, preventing them from entering the underground drainage system.

[0003] Because the inner walls of the passageway can accumulate sludge, grease, plastic bags and other debris, and even hard objects such as tree branches can get stuck, the effective water passage area of ​​the passageway is reduced and the drainage capacity is significantly reduced, which can cause water accumulation on the road and pose a safety hazard. Therefore, the passageway is cleared before heavy rainfall to ensure the drainage capacity of the water passageway.

[0004] However, in the existing technology, the dredging of such vertical water flow channels is mostly done by simple hooks and digging, which is inefficient and difficult to completely remove the debris tightly attached to the inner wall. There is a lack of a special tool that can quickly, effectively and comprehensively clean the deposits on the inner wall of the channel and handle hard foreign objects. Utility Model Content

[0005] The purpose of this invention is to provide a device for clearing water flow channels to solve the problems mentioned in the background art.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 5 A device for clearing water flow channels, used for clearing vertical water flow channels on the ground. The bottom of the water flow channel is an underground drainage ditch or directly connected to a pre-buried underground drainage pipe. The water flow channel is a metal pipe. A filter screen setting part is provided at the top of the water flow channel. The filter screen setting part adopts a rectangular concave design, and a suitable filter screen component can be set inside it to block pollutants from entering when the water flow channel is draining normally. like Figure 1 and Figure 3 A device for unblocking water flow channels includes a rectangular positioning seat 1. The bottom of the rectangular positioning seat 1 is adapted to a filter screen setting part. After the filter screen is removed, the rectangular positioning seat 1 can be snapped into the filter screen setting part. A guide sleeve 2 is fixedly connected to the top of the rectangular positioning seat 1. A vertical connecting rod 3 is slidably connected in the guide sleeve 2. The bottom of the vertical connecting rod 3 passes through the rectangular positioning seat 1 and is welded and fixed to a mounting seat 4. A compression ring 5 is installed at the bottom of the mounting seat 4. The radius of the compression ring 5 is adapted to the inner radius of the water flow channel and can move closely against the inside of the water flow channel. The vertical connecting rod 3 can drive the compression ring 5 to move into the water flow channel.

[0017] The extrusion ring 5 is mounted on the mounting base 4 by bolts, allowing extrusion rings 5 ​​of different radii to be installed for use in water flow channels of different specifications.

[0018] like Figure 3 Two sets of mutually perpendicular cutting blades 501 are fixedly connected to the bottom of the extrusion ring 5. The cutting blades 501 are used to cut off foreign objects such as tree branches stuck inside the channel when the extrusion ring 5 moves down along the water flow channel.

[0019] like Figure 1 and Figure 3 The bottom of the rectangular positioning seat 1 has an annular recess 101, which is used to accommodate the extrusion ring 5. When the extrusion ring 5 moves upward into the annular recess 101, the cutting blade 501 will also be retracted into the annular recess 101, thus improving the safety of the equipment.

[0020] like Figure 1 and Figure 2 A handle 301 is fixedly connected to the top of the vertical link 3, and an anti-slip rubber sleeve is fixed to the outer surface of the handle 301.

[0021] like Figure 1 and Figure 2 A vertical slide groove 201 is provided on one side of the guide sleeve 2, and a rectangular block 202 is fixedly connected to one side of the vertical connecting rod 3. The rectangular block 202 can slide up and down along the vertical slide groove 201. A foot pedal 6 is fixedly connected to one end of the rectangular block 202 and located outside the guide sleeve 2. The top of the foot pedal 6 is provided with anti-slip texture.

[0022] like Figure 1 , Figure 2 and Figure 4 The vertical connecting rod 3 has a positioning hole 7. A fixing mechanism that works with the positioning hole 7 is fixedly connected to one side of the top of the guide sleeve 2. The fixing mechanism includes a fixing tube 801 and a horizontally movable fixing shaft 806. When the vertical connecting rod 3 moves upward, so that the extrusion ring 5 is retracted into the annular concave 101, the positioning hole 7 moves upward with the vertical connecting rod 3 to a position that is exactly aligned with the fixing shaft 806, so that the fixing shaft 806 passes through the positioning hole 7, restricting the vertical movement of the vertical connecting rod 3 and preventing the extrusion ring 5 and the cutting blade 501 from dislodging from the annular concave 101. One end of the fixed tube 801 is fixed to the guide sleeve 2, and one end of the fixed shaft 806 is curved to reduce the friction between it and the vertical connecting rod 3. A tension spring 802 is fixedly connected inside the fixed tube 801. One end of the tension spring 802 is fixedly connected to a movable column 803. The tension spring 802 is in a stretched state and exerts a pulling force on the movable column 803 in the direction of the tension spring 802. A horizontal groove 804 is provided on the fixed tube 801. A connecting plate 805 is fixedly connected to the top of the movable column 803. The top of the connecting plate 805 passes through the horizontal groove 804 and is fixedly connected to the fixed shaft 806, which can drive the fixed shaft 806 to move horizontally.

[0023] The working principle of the water flow channel unblocking device provided by this utility model is as follows: Before heavy rainfall arrives, it is necessary to dredge the water flow channel and improve flood control capabilities. First, take out the filter screen component in the filter screen setting part above the water flow channel, then insert the rectangular positioning seat 1 into the filter screen setting part, and then pull the fixing shaft 806 to one side to separate the fixing shaft 806 and the positioning hole 7. Then move the vertical connecting rod 3 down, which will drive the mounting base 4 and the extrusion ring 5 down into the water flow channel. The extrusion ring 5 moves closely against the inner wall of the water flow channel. During the downward movement, it will scrape off the blockages in the water flow channel and the sludge, plastic bags and other debris attached to the inner wall of the water flow channel, thereby clearing the water flow channel. The mounting base 4 and the compression ring 5 need to be lowered. You can step on the foot pedal 6. The foot pedal 6 drives the vertical connecting rod 3 to move down through the rectangular block 202, so that the vertical connecting rod 3 can apply stronger downward pressure to the mounting base 4 and the compression ring 5, and better squeeze the sludge, plastic bags and other debris on the inner wall of the water flow channel.

[0024] After the blockage is cleared, the vertical connecting rod 3 is moved upward, causing the mounting base 4 and the compression ring 5 to move upward into the annular recess 101. At this time, the positioning hole 7 can be moved upward to the same height as the fixed shaft 806. Under the tension of the tension spring 802, the movable column 803 is moved. The movable column 803 drives the fixed shaft 806 to move through the connecting plate 805, so that the fixed shaft 806 passes through the positioning hole 7, restricting the vertical movement of the vertical connecting rod 3, so that the mounting base 4 and the compression ring 5 will not move downward.

[0025] Compared with related technologies, the water flow channel clearing device provided by this utility model has the following beneficial effects: This invention uses a vertical connecting rod 3 to drive the squeezing ring 5 downwards. By moving the squeezing ring 5 close to the water flow channel, blockages and debris such as sludge and plastic bags attached to the inner wall of the water flow channel can be scraped off, thoroughly clearing the water flow channel and preventing residual debris from adhering to the inner wall of the channel. This ensures that the water flow channel has maximum drainage capacity before heavy rainfall, reducing the possibility of water accumulation on the ground. At the same time, when the squeezing ring 5 moves downwards, the foot pedal 6 can be stepped on to provide assistance, further clearing blockages and debris from the inner wall of the channel.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
