Description

Technical Field

[0001] This utility model relates to the field of river cleaning technology, and in particular to a river sludge suction device for municipal cleaning. Background Technology

[0002] The working principle of the river sludge suction device is mainly based on the principle of negative pressure suction. During the sludge suction process, the device generates negative pressure to suck the sludge in the river into the device. Subsequently, the sludge is transported to a designated location, such as a sludge treatment plant or a stockpile area, through a conveying system. Throughout the process, the control system is responsible for monitoring and adjusting the working status of the sludge suction device and the conveying system to ensure sludge suction efficiency and operational safety.

[0003] A Chinese patent discloses a river sludge suction device for municipal cleaning (authorization announcement number CN207794168U). This patented technology can convert the rotation of the cam into vibration of the connecting block, the movable ring and the rubber layer, thereby removing the dry mud and sand adhering to the inner wall of the pipe through the protrusion and discharging it.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: Traditional river sludge suction devices often adopt a fixed or integrated sludge suction pipe design. This design is relatively simple in the manufacturing and installation stages, but it brings many inconveniences in actual use. Due to the complex and changeable river environment, the sludge suction pipe is prone to wear, blockage or damage during long-term operation. In particular, when encountering hard objects or complex terrain, the risk of pipe damage increases significantly. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing devices do not fully consider the vulnerability and replacement needs of the suction pipe in their design. Therefore, we propose a river suction device for municipal cleaning.

[0006] To achieve the above objectives, this application adopts the following technical solution: a river sludge suction device for municipal cleaning, comprising a sludge suction device body, an adjusting column fixedly connected to the front end of the sludge suction device body, a rotating column rotatably connected inside the adjusting column, a sludge suction pipe provided inside the rotating column, arc-shaped blocks fixedly connected to both sides inside the adjusting column, adjusting grooves provided on both sides of the rotating column, a push block slidably connected inside the adjusting groove, an insertion rod fixedly connected to the side of the push block near the inside of the adjusting groove, a through hole provided on the side of the adjusting groove away from the arc-shaped block, and insertion holes provided on both sides of the sludge suction pipe.

[0007] Preferably, the size of the insertion rod is adapted to the size of the insertion hole, and the surface of the insertion rod is inserted into the interior of the insertion hole.

[0008] Preferably, screws are provided on both sides of the adjusting column, and screw holes are provided on both sides of the rotating column.

[0009] Preferably, both ends of the push block are fixedly connected to sliders, both ends of the adjustment groove are provided with sliding grooves, and the surface of the slider is slidably connected to the inside of the sliding groove.

[0010] Preferably, the inner wall of the adjusting column is provided with two annular grooves, and two annular blocks are fixedly connected to the surface of the rotating column.

[0011] Preferably, a storage spring is fixedly connected to the side of the insertion rod near the push block, and the side of the storage spring away from the push block is fixedly connected to the inside of the adjustment groove.

[0012] Preferably, a sealing gasket is provided at the rear end of the adjustment column.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] In this invention, the operator rotates the rotating column, causing the rotating column to drive the push block and the insertion rod to rotate, so that the push block contacts the thicker end of the arc-shaped block. At the same time, the arc-shaped block squeezes the push block, causing the insertion rod to be inserted into the insertion hole for fixation. The above arrangement allows the operator to replace or maintain the suction pipe. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a river sludge suction device for municipal cleaning, including a suction device body 1. An adjusting column 2 is fixedly connected to the front end of the suction device body 1. A rotating column 3 is rotatably connected inside the adjusting column 2. A suction pipe 4 is provided inside the rotating column 3. Arc-shaped blocks 5 are fixedly connected to both sides inside the adjusting column 2. Adjusting grooves 6 are opened on both sides of the rotating column 3. Push blocks 7 are slidably connected inside the adjusting grooves 6. An insertion rod 8 is fixedly connected to the side of the push block 7 near the inside of the adjusting groove 6. A through hole 10 is opened on the side of the adjusting groove 6 away from the arc-shaped blocks 5. Insertion holes 11 are opened on both sides of the suction pipe 4. When the operator rotates the rotating column 3, the rotating column 3 drives the push block 7 and the insertion rod 8 to rotate, so that the push block 7 contacts the thicker end of the arc-shaped block 5. At the same time, the arc-shaped block 5 squeezes the push block 7, causing the insertion rod 8 to be inserted into the insertion hole 11 for fixation. The above configuration allows the operator to replace or maintain the suction pipe 4.

[0023] Reference Figure 3 - Figure 5 As shown in this embodiment: the size of the insertion rod 8 is adapted to the size of the insertion hole 11, and the surface of the insertion rod 8 is inserted into the interior of the insertion hole 11. By adapting the size of the insertion rod 8 to the size of the insertion hole 11, the size of the insertion rod 8 is precisely matched with the opening size of the insertion hole 11. This not only achieves a tight connection between the insertion rod 8 and the insertion hole 11, but also ensures the stability and sealing effect of the insertion rod 8 in the insertion hole 11.

[0024] Reference Figure 3 As shown in this embodiment: screws 12 are provided on both sides of the adjusting column 2, and screw holes 13 are provided on both sides of the rotating column 3. By setting the screws 12 and screw holes 13, the operator inserts the screws 12 into the screw holes 13, so that the position of the rotating column 3 rotates. This avoids the problem that the contact between the push block 7 and the arc block 5 is unstable due to the rotation of the rotating column 3, which may cause the insertion rod 8 to fall out of the insertion hole 11 and shake.

[0025] Reference Figure 3 and Figure 4As shown in this embodiment: both ends of the push block 7 are fixedly connected to sliders 14, and both ends of the adjustment groove 6 are provided with sliding grooves 15. The surface of the slider 14 is slidably connected to the inside of the sliding groove 15. When the operator moves the push block 7, the push block 7 drives the slider 14 to slide inside the sliding groove 15. Through the above settings, the position of the push block 7 can be precisely adjusted. In addition, the sliding connection design between the slider 14 and the sliding groove 15 not only ensures the smoothness of operation, but also improves the durability of the device. In practical applications, this structural design can effectively reduce wear and extend the service life of the equipment.

[0026] Reference Figure 3 As shown in this embodiment: the inner wall of the adjusting column 2 is provided with two annular grooves 17, and two annular blocks 18 are fixedly connected to the surface of the rotating column 3. When the operator rotates the rotating column 3, the rotating column 3 drives the annular blocks 18 to rotate inside the annular grooves 17. Through the above arrangement, the tightly fitted annular blocks 18 and annular grooves 17 can ensure smoothness and stability during the rotation process and reduce the risk of equipment failure.

[0027] Reference Figure 3 As shown in this embodiment: a storage spring 9 is fixedly connected to the side of the insertion rod 8 near the push block 7, and the side of the storage spring 9 away from the push block 7 is fixedly connected to the inside of the adjustment groove 6. When the worker makes the push block 7 contact the thicker end of the arc block 5, the push block 7 squeezes the storage spring 9 to compress and store force, and at the same time, the insertion rod 8 is inserted into the insertion hole 11 for fixation. When the worker releases the contact between the push block 7 and the arc block 5, the push block 7 is quickly pushed under the action of the rebound force of the storage spring 9, so that the push block 7 drives the insertion rod 8 to release the limit between the insertion hole 11 and the block 5, so that the worker can disassemble and replace the suction pipe 4.

[0028] Reference Figure 3 As shown in this embodiment, a sealing gasket 16 is provided at the rear end of the inner side of the adjusting column 2. The sealing gasket 16 at the rear end of the inner side of the adjusting column 2 plays a key sealing role in the process of the sludge suction device body 1 treating sludge, thereby improving the sealing performance and working efficiency of the entire system.

[0029] Working principle: The operator rotates the rotating column 3, causing the push block 7 and the insertion rod 8 to rotate. This causes the push block 7 to contact the thicker end of the arc-shaped block 5, while the arc-shaped block 5 presses against the push block 7, causing the insertion rod 8 to be inserted into the insertion hole 11 for fixation. This setup allows the operator to replace or maintain the suction pipe 4. The size of the insertion rod 8 is precisely matched to the size of the insertion hole 11, ensuring a tight fit between the insertion rod 8 and the insertion hole 11, and guaranteeing proper insertion. The stability and sealing effect of rod 8 in the insertion hole 11 are achieved through the setting of screw 12 and screw hole 13. When the operator inserts screw 12 into screw hole 13, the position of rotating column 3 is rotated. This prevents unstable contact between push block 7 and arc block 5 caused by the rotation of rotating column 3, which could easily cause rod 8 to fall out of the insertion hole 11 and wobble. When the operator moves push block 7, push block 7 drives slider 14 to slide inside slide groove 15. Through the above settings, precise adjustment of the position of push block 7 is achieved. In addition, the distance between slider 14 and slide groove 15 is also controlled. The sliding connection design not only ensures smooth operation but also improves the durability of the device. In practical applications, this structural design can effectively reduce wear and extend the service life of the equipment. When the operator rotates the rotating column 3, the rotating column 3 drives the annular block 18 to rotate inside the annular groove 17. Through the above-mentioned arrangement, the tightly fitted annular block 18 and annular groove 17 can ensure smoothness and stability during rotation, reducing the risk of equipment failure. When the operator makes the push block 7 contact the thicker end of the arc block 5, the push block 7 compresses the energy storage spring 9 to store energy, and at the same time, the insertion rod 8 is inserted into the insertion hole 11 for fixation. When the operator releases the contact between the push block 7 and the arc block 5, the push block 7 is quickly pushed under the action of the rebound force of the energy storage spring 9, so that the push block 7 drives the insertion rod 8 to contact the limit between the insertion hole 11, so that the operator can disassemble and replace the suction pipe 4. The rear end of the adjusting column 2 is designed with a sealing gasket 16, which plays a key sealing role in the process of the suction device body 1 treating mud, thereby improving the sealing performance and working efficiency of the entire system.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
