Description

Technical Field

[0001] This utility model relates to the technical field of dredging devices, specifically a dredging device for water conservancy projects. Background Technology

[0002] Water conservancy projects are a general term for various engineering projects established to utilize and protect groundwater and environmental water resources. The construction of water conservancy projects enables the allocation of water from nature for human use, and water conservancy can prevent floods and disasters. In water conservancy projects, it is often necessary to remove silt. Silt accumulation can prevent water from draining quickly during natural floods, so it is necessary to remove the accumulated silt regularly. Currently, most silt removal is done manually, which is very time-consuming and labor-intensive. Moreover, many existing silt removal devices still leave silt residue after removal, and the silt removal effect is not good enough. Therefore, a water conservancy project silt removal device is provided to solve the above problems.

[0003] The shortcomings of existing dredging equipment are:

[0004] 1. Prior art document CN211368834U discloses a sludge removal device for water conservancy projects, "including a sludge removal device body and an electric telescopic rod. A handle is bolted to the side of the sludge removal device body, and a hinged door is connected to the left side of the sludge removal device body. Rollers are fixedly installed on both sides of the sludge removal device body, and the rollers are connected to a movable shaft via tracks. The movable shaft and the rotating blade are both located inside the feed inlet, which is located on the right side of the sludge removal device body. A sleeve is fixedly installed on the upper surface of the sludge removal device body, and..." A spring is fixedly installed inside the sleeve, and a scraper is fixedly installed at the lower end of the inner rod, with the scraper movably positioned within the collection groove. This silt-clearing device for water conservancy projects utilizes the kinetic energy of the drive mechanism to rotate the blades, offering advantages in energy saving and environmental protection. The rotating blades effectively prevent silt blockage at the feed inlet and automatically remove silt from the blades. However, during use, when shoveling silt from the ground, silt residue remains, failing to completely remove it, resulting in poor silt-clearing performance.

[0005] 2. Currently, most methods for dredging water conservancy projects involve excavating and transporting the sludge and manually removing it. However, this method involves a large amount of work, which wastes time, manpower, and resources, and the efficiency of cleaning sludge from water conservancy projects is low. Utility Model Content

[0006] The purpose of this utility model is to provide a dredging device for water conservancy projects to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dredging device for water conservancy projects, comprising a housing, a cleaning structure and a sludge pump, wherein a support plate is installed on the inner wall of the housing, a sludge storage tank is installed on the top surface of the support plate, and a cleaning structure is installed on the bottom surface of the support plate;

[0008] The cleaning structure includes a water pump, a water tank, a nozzle, a scraper, and a brush. The water tank is installed on the bottom surface of the support plate. The water pump is installed on the inner wall of one side of the tank and is located below the support plate. The output end of the water pump is connected to a spray pipe, and a nozzle is installed at the tail end of the spray pipe and is located below the tank.

[0009] An arc-shaped scraper is installed on the bottom surface of the box, and the scraper is located on one side of the nozzle. A brush is installed on the bottom surface of the scraper.

[0011] Preferably, a motor box is installed on one side surface of the housing, and a shovel block is installed on one side surface of the housing, with the shovel block located below the motor box.

[0012] Preferably, a servo motor is installed on the inner top wall of the motor box, and a telescopic rod is connected to the output end of the servo motor. A cutting blade is installed at the bottom end of the telescopic rod via a shaft, and the cutting blade is located above the shovel block.

[0013] Preferably, a flap is installed on the side of the box away from the suction pipe via a hinge, and a handle is installed on one side of the flap.

[0014] Preferably, the input end of the water pump is connected to a suction pipe, and the tail end of the suction pipe extends into the interior of the water tank.

[0015] Preferably, the box is equipped with casters at all four corners of its bottom.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model features a cleaning structure including a water pump, a water tank, a nozzle, a scraper, and a brush. After the shovel removes the silt, residual sticky silt remains. The water pump draws water from the water tank through a suction pipe, and then sprays the water from the nozzle through a spray pipe at the pump's output end, thus washing away the silt adhering to the ground. The water dissolves the adhering silt, and the arc-shaped scraper, which moves with the tank, drives the brush at its bottom to brush away the dissolved mud and water, thereby reducing the amount of residual silt on the ground, improving the silt removal effect of the device, and increasing its practicality.

[0018] 2. This utility model is equipped with a cutting blade, a sludge pump, a sludge suction plate, a sludge suction pipe, and a sludge discharge pipe. The cutting blade is driven by the output of a servo motor to rotate, thereby stirring and cutting the sludge. This facilitates the removal of the loosened sludge after cutting. The shovel extends into the loose sludge to scoop it up, collecting the sludge in the shovel. Subsequently, the sludge pump, in conjunction with the sludge suction pipe and the sludge suction plate, removes the sludge accumulated on the shovel. The absorbed sludge is discharged into a sludge storage tank through the sludge discharge pipe for temporary collection. This automatic sludge removal for water conservancy projects avoids the waste of manpower and resources, eliminates the need for manual sludge removal, reduces the workload of workers, and thus improves work efficiency.

[0027] Example 1:

[0028] Please see Figure 1 , Figure 2 and Figure 4 A dredging device for water conservancy projects includes a box body 1, a cleaning structure 3 and a sludge pump 4. A support plate is installed on the inner wall of the box body 1, and a sludge storage box 2 is installed on the top surface of the support plate.

[0029] Specifically, the box 1 provides installation space for the dredging device, while the support plate supports the sludge storage box 2 and divides the box 1. The sludge storage box 2 is provided with a sludge inlet, so that the sludge discharged from the sludge outlet pipe 12 enters the interior of the sludge storage box 2 and is temporarily stored and collected.

[0030] like Figure 3As shown, a dredging device for water conservancy projects includes a cleaning structure 3. The cleaning structure 3 is installed on the bottom surface of a support plate. The cleaning structure 3 includes a water pump 301, a water tank 302, a nozzle 303, a scraper 304, and a brush 305. The water tank 302 is installed on the bottom surface of the support plate. The water pump 301 is installed on the inner wall of one side of the tank body 1 and is located below the support plate. The output end of the water pump 301 is connected to a water spray pipe. The nozzle 303 is installed at the tail end of the water spray pipe and is located below the tank body 1. The scraper 304 is installed on the bottom surface of the tank body 1 and is located on one side of the nozzle 303. The brush 305 is installed on the bottom surface of the scraper 304. The input end of the water pump 301 is connected to a suction pipe, and the tail end of the suction pipe extends into the interior of the water tank 302.

[0031] Specifically, after the shovel block 9 removes the silt, some sticky silt remains. Water is drawn from the water tank 302 by the water pump 301 and sprayed from the nozzle 303 through the water pipe to wash away the silt adhering to the ground. The water dissolves the adhering silt, and the mixed mud and water are brushed away by the arc-shaped scraper 304 that moves with the box body 1 and the brush 305 on the scraper 304. This reduces the amount of sticky silt remaining on the ground and improves the sludge removal effect of the sludge removal device.

[0032] A motor box 5 is installed on one side surface of the housing 1, and a shovel block 9 is installed on one side surface of the housing 1. The shovel block 9 is located below the motor box 5. A servo motor 6 is installed on the inner top wall of the motor box 5. A telescopic rod 7 is connected to the output end of the servo motor 6. A cutting blade 8 is installed at the bottom end of the telescopic rod 7 through a shaft. The cutting blade 8 is located above the shovel block 9.

[0033] Specifically, the motor box 5 provides installation space for the servo motor 6 and prevents the servo motor 6 from being damaged by water ingress. The rotation of the output end of the servo motor 6 drives the telescopic rod 7 to rotate, and the rotating telescopic rod 7 drives the cutting blade 8 to rotate through the shaft, thereby cutting and loosening the silt so that the silt can be sucked away by the sludge suction plate 10. The height of the cutting blade 8 can be adjusted by the telescopic rod 7, and the shovel 9 will extend into the loosened silt after cutting to shovel and facilitate the collection of silt.

[0034] A flip cover 14 is installed on the side of the box body 1 away from the suction pipe 11 via a hinge. A handle is installed on one side of the flip cover 14. Universal wheels 13 are installed at the four corners of the bottom of the box body 1.

[0035] Specifically, the sludge in the sludge storage box 2 can be emptied by opening the flip cover 14, which facilitates a new round of sludge removal. The box 1 can be moved by the casters 13, which facilitates continuous sludge removal.

[0036] Example 2: Figure 1 As shown, a sludge pump 4 is installed on the top surface of the tank 1. The input end of the sludge pump 4 is connected to a sludge suction pipe 11. A sludge suction disc 10 is installed at the tail end of the sludge suction pipe 11. The output end of the sludge pump 4 is connected to a sludge discharge pipe 12, and the tail end of the sludge discharge pipe 12 is located above the sludge storage tank 2.

[0037] Specifically, the shovel block 9 extends into the loosened silt after cutting to shovel and collect the silt. Then, the sludge pump 4, through the cooperation of the sludge suction plate 10 and the sludge suction pipe 11, sucks away the silt accumulated on the shovel block 9. The absorbed silt is discharged into the sludge storage tank 2 through the sludge discharge pipe 12 for collection, thereby automatically removing the silt from the water conservancy project, avoiding the waste of a lot of manpower and material resources, eliminating the need for manual shoveling of silt, and thus improving the work efficiency of the staff.

[0038] Working principle: Before using this dredging device to clean silt, fill the water tank 302 with water, then start the servo motor 6. The output of the servo motor 6 drives the telescopic rod 7 to rotate, and the rotating telescopic rod 7 drives the cutting blade 8 to rotate through the shaft, thereby cutting and loosening the silt. The loosened silt accumulates on the shovel block 9.

[0039] Then, the sludge pump 4 is started. The sludge pump 4, through the cooperation of the sludge suction plate 10 and the sludge suction pipe 11, sucks up the sludge accumulated on the shovel block 9 and discharges it into the sludge storage tank 2 through the sludge discharge pipe 12. In this way, the sludge is automatically sucked up, avoiding the waste of manpower and material resources and improving the work efficiency of the staff.

[0040] After the shovel block 9 removes the silt, some sticky silt will remain. Water is drawn from the water tank 302 by the water pump 301 and then sprayed from the nozzle 303 through the water spray pipe to wash away the silt adhering to the ground. The water dissolves the adhering silt, and then the curved scraper 304 and the brush 305 work together to brush away the dissolved mud and water, thereby reducing the amount of silt adhering to the ground and improving the sludge removal effect of the sludge removal device.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
