Technical Field

[0001] The utility model relates to the technical field of silt removal devices, in particular to a silt removal device for water conservancy projects. Background Art

[0002] Water conservancy projects mainly include various types of projects such as flood control, drainage, irrigation, hydropower generation, water diversion, tidal flat management, soil and water conservation, and water resource protection. Water conservancy projects also refer to projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects.

[0003] However, in the water conservancy projects in the prior art, pipeline dredging is a very troublesome task. Silt is easily deposited inside cement pipes, especially those with slow water flow. According to a Chinese patent application number 202122740037.6, a dredging device for water conservancy projects uses an electric motor to drive the dredging mechanism to rotate. When the motor drives the dredging mechanism to rotate, the movable rod slides outward inside the fixed rod under the action of centrifugal force, so that the dredging plate automatically fits the inner wall of the pipe to perform dredging. However, in the prior art, the cross-section of the pipe is generally circular, and the fit between the dredging plate and the pipe is poor. Therefore, an improved dredging device for water conservancy projects is needed to address this problem. Utility Model Content

After the card block is inserted into the card slot, the card block is limited by the claws inserted into the limiting groove to fix it; this is more convenient when the card block and the elastic scraper need to be disassembled and replaced later; just lift the claws.

[0007] Preferably, the claw is made of elastic metal material, which provides it with sufficient structural strength and allows it to bend toward the inside of the slot under its own elastic action, so that the claw can automatically engage in the limiting slot.

[0008] Preferably, a telescopic rod is fixedly provided on the outer surface of the shell, and the movable end of the telescopic rod is fixedly connected to the slider. A spring is provided on the movable sleeve on the outer surface of the telescopic rod, which can automatically drive the telescopic rod to extend, thereby pushing the slider to move in the direction close to the track assembly.

The elastic scraper part of the present invention can be quickly and conveniently replaced as needed. When replacing the scraper, the claw is pried with a tool so that the claw is bent and disengaged from the limit slot, so that the claw no longer engages the card block. At this time, the card block can be pulled out of the card slot, so that the scraper can be removed. When installing a new scraper, it is only necessary to forcefully insert the card block into the card slot. When the card block is inserted, it will first squeeze the claw, so that the claw bends and opens to both sides. After the card block is completely stuck in the slot, the claw can automatically reset under its own elastic action, so that the claw is stuck in the limit slot, thereby completing the fixation of the card block. In this way, the entire replacement process of the scraper is convenient and fast. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-3 The utility model provides a technical solution: a silt removal device for water conservancy projects, including a shell 1, the outer surface of the shell 1 is provided with a driving mechanism that facilitates the movement of the device inside the pipeline, the driving mechanism includes a slide 2, a slider 3, a rotating support arm 4, a transmission support arm 5, and a crawler assembly 6. The outer surface of the shell 1 is provided with a slide 2, and the outer side of the slide 2 is movably engaged with the slider 3. The outer surface of the shell 1 is provided with a rotating support arm 4 on one side of the slider 3 through a rotating shaft. The outer surface of the slider 3 is provided with a transmission support arm 5 through a rotating shaft. The upper end of the rotating support arm 4 A crawler assembly 6 is movably provided through a rotating shaft, and a cleaning mechanism for scraping the inner side wall of the pipe to clean the inner side wall of the pipe is provided on one side of the surface of the shell 1. The cleaning mechanism includes a rotating motor 7, a rotating disk 8, a slot 9, a block 10, and an elastic scraper 11. A rotating motor 7 is fixedly provided at one end of the shell 1, and a rotating disk 8 is fixedly provided at the output shaft end of the rotating motor 7 through a coupling. A plurality of slots 9 are evenly and fixedly provided on the outer surface of the rotating disk 8, and a block 10 is movably engaged with the inside of the slot 9. An elastic scraper 11 is fixedly provided on the upper end of the block 10.

[0018] The clamping block 10 is provided with limiting grooves 12 on both sides of the surface, and claws 13 are fixedly provided on both sides of the inside of the clamping slot 9. The claws 13 are movably engaged with the inside of the limiting grooves 12. After the clamping block 10 is inserted into the clamping slot 9, the clamping block 10 is limited by the claws 13 being inserted into the limiting grooves 12 to fix it. This makes it more convenient to disassemble and replace the clamping block 10 and the elastic scraper 11 later; it is only necessary to lift the claws 13.

[0019] The claw 13 is made of an elastic metal material, which has sufficient structural strength and allows the claw 13 to bend toward the inside of the slot 9 under its own elastic action, so that the claw 13 can automatically engage with the inside of the limiting slot 12;

[0020] A telescopic rod 14 is fixedly provided on the outer surface of the housing 1. The movable end of the telescopic rod 14 is fixedly connected to the slider 3. A spring 15 is movably sleeved on the outer surface of the telescopic rod 14. The spring 15 can automatically drive the telescopic rod 14 to extend, thereby pushing the slider 3 to move toward the direction of the crawler assembly 6. In this way, the transmission arm 5 can push the crawler assemblies 6 away from each other, so that the entire device can be tightened and fixed inside the pipe that needs to be desilted.

[0021] A drive motor 16 is fixedly provided on the outer surface of the crawler assembly 6. The power output end of the drive motor 16 is transmission-connected to the power input end of the crawler assembly 6. The drive motor 16 can drive the crawler assembly 6 to work.

[0022] One end of the transmission arm 5 close to the track assembly 6 is movably connected to the track assembly 6 via a rotating shaft, and the transmission arm 5 can drive the track assembly 6 to move.

[0023] Working principle: When using this device, the whole device can move inside the pipe through the crawler assembly 6. At this time, under the action of the elastic scraper 11's own elasticity, the scraper can be closely attached to the inner side wall of the pipe. Figure 1 The rotating disc 8 is driven to rotate clockwise by the rotating motor 7 in the perspective shown, so that the scraper can be used to clean the dirt attached to the inner wall of the pipe. The elastic scraper 11 of the device has a smooth shape, and the front shovel part of the scraper is more likely to be tangent to the inner side wall of the pipe, thereby facilitating the cleaning and dredging of the inner side wall of the pipe.

[0024] At the same time, the elastic scraper 11 part of the present device can be quickly and conveniently replaced as needed. When replacing the scraper, the claw 13 is pried by a tool, so that the claw 13 is bent and disengaged from the limiting slot 9, so that the claw 13 no longer engages the block 10. At this time, the block 10 can be pulled out of the slot 9, so that the scraper can be removed. When installing a new scraper subsequently, it is only necessary to insert the block 10 into the slot 9 with force. When the block 10 is inserted, the claw 13 will first be squeezed, so that the claw 13 bends and opens to both sides. After waiting for the block 10 to be completely stuck in the slot 9, the claw 13 can automatically reset under the action of its own elasticity, so that the claw 13 is stuck in the limiting slot 9, thereby completing the fixation of the block 10, and the entire replacement process of the scraper is convenient and quick.
