Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and more particularly to a silt clearing device for water conservancy projects. Background Art

[0002] Water conservancy projects, also known as water engineering, are constructed to control and allocate natural surface and groundwater to eliminate harm and promote benefits. They control water flows, prevent floods, and regulate and distribute water to meet the water needs of people's lives and production. To achieve these goals, water conservancy projects require the construction of various hydraulic structures, including dams, dikes, spillways, sluices, inlets, channels, ferries, rafts, and fishways.

[0003] For example, a Chinese patent discloses a dredging device for water conservancy projects, and the patent number is CN108411966B. In this patent, the bottom end of the threaded sleeve passes through the inner shell and extends to the inside of the inner shell, so that the silt will not be tightly accumulated together, making it easier to clean it after it is loosened. A protective box is fixedly connected to the top of the bottom plate and located on one side of the box body. The loosened silt can be cleaned with a sludge pump, and the silt can be quickly removed.

[0004] The above-mentioned dredging device adopts the method of lifting and lowering a threaded sleeve to complete the stirring of the silt. Due to the different depths of the silt at the bottom of the water conservancy project pool, it is easy for the silt to enter the threaded rod when the threaded sleeve is adjusted, which makes the threaded sleeve unable to process the silt subsequently. At the same time, a sludge pump is used to extract the silt at the bottom of the pool on a large scale at the same time, resulting in a large amount of silt extraction, which leads to the problem of clogging of the sludge pump when extracting a large amount of silt, thereby reducing the stability of silt transportation and affecting the service life of the silt treatment device. Therefore, the above-mentioned dredging device cannot meet the silt treatment needs of water conservancy projects. Summary of the Invention

A water pump 17 is provided on the top of the treatment box 11, and an extraction pipe 18 is installed on the outer wall of the water pump 17;

[0038] A No. 2 motor 301 is provided on the inner bottom wall of the sludge treatment mechanism assembly 3, and the output shaft of the No. 2 motor 301 is connected to the No. 2 transmission 302 via a coupling. A No. 1 crushing rod 303 is provided on the inner wall of the No. 2 transmission 302, and the No. 1 crushing rod 303 forms a rotating structure with the No. 2 motor 301 through the No. 2 transmission 302.

The inner wall of the No. 2 gear plate 305 is fixedly connected to the No. 2 crushing rod 306, and the No. 2 crushing rod 306 forms an integrated structure with the No. 1 gear plate 304 via the No. 2 gear plate 305.

[0039] By starting the No. 2 motor 301 provided on the inner bottom wall of the sludge processing mechanism assembly 3, the No. 2 motor 301 drives the No. 1 crushing rod 303 to rotate through the No. 2 transmission 302, so that the No. 1 crushing rod 303 processes the large pieces of sludge. Since the inner wall of the No. 1 gear plate 304 is fixedly connected to the No. 1 crushing rod 303, and the outer wall of the No. 1 gear plate 304 is meshedly connected to the No. 2 gear plate 305, the No. 2 gear plate 305 drives the No. 2 crushing rod 306 to rotate, so that the No. 2 crushing rod 306 cooperates with the No. 1 crushing rod 303 to complete the crushing of the large pieces of sludge.

[0040] The outer wall of the second gear plate 305 is meshedly connected with the half gear plate 307, and the inner wall of the half gear plate 307 is fixedly connected to the first fixing rod 308. The first fixing rod 308 forms a rotating structure with the second gear plate 305 through the half gear plate 307. The outer wall of the first fixing rod 308 is fixedly connected to the connecting plate 12. The connecting plate 12 is fixedly connected to the silt shovel plate 14 through the second fixing rod 13. The silt shovel plate 14 forms an integrated structure with the connecting plate 12 through the second fixing rod 13.

[0041] At the same time, since the outer wall of the half gear plate 307 is meshed with the second gear plate 305, and the inner wall of the half gear plate 307 is fixedly connected to the first fixing rod 308, the first fixing rod 308 is rotated through the half gear plate 307, so that the connecting plate 12 fixed to the outer wall of the first fixing rod 308 rotates together, and since the inner wall of the connecting plate 12 is fixedly connected to the second fixing rod 13, and the outer wall of the second fixing rod 13 is fixedly connected to the silt shovel plate 14, the silt shovel plate 14 is rotated following the first fixing rod 308 through the connecting plate 12, so that the angle of the silt shovel plate 14 is adjusted, so that the silt in the silt shovel plate 14 flows into the sewage trough 15, completing the treatment of the bottom silt;

[0042] The inner wall of the silt shovel plate 14 is an arc-shaped structure, and the sewage trough 15 is opened at the bottom end of the silt shovel plate 14. The silt processing mechanism assembly 3 and the silt shovel plate 14 are arranged on both sides of the No. 2 conveying pipe 16, and the silt processing mechanism assembly 3 forms an integrated conveying structure through the No. 2 conveying pipe 16 and the silt shovel plate 14;

[0043] The hull 1 drives the silt shovel 14 to move along the bottom, and then the silt shovel 14 shovels the silt on the bottom, so that the silt falls into the silt shovel 14, and then by starting the sludge pump 10, the suction of the sludge pump 10 is transported to the telescopic sludge pipe 4 through the No. 1 delivery pipe 8. Since the telescopic sludge pipe 4 and the No. 2 delivery pipe 16 are installed on both sides of the sludge treatment mechanism assembly 3, the No. 2 delivery pipe 16 extracts the silt in the silt shovel 14 through the sewage trough 15 opened on the inner wall of the silt shovel 14

[0044] A limiting frame 9 and a treatment box 11 are installed at both ends of the sludge pump 10, and the treatment box 11 forms an integrated structure through the sludge pump 10 and the limiting frame 9. The inner wall of the treatment box 11 is fixedly connected with a diverter plate 1101, and the inner wall of the diverter plate 1101 is provided with a high-pressure nozzle 1102. There are several high-pressure nozzles 1102, and several high-pressure nozzles 1102 are equidistantly arranged on the inner wall of the diverter plate 1101, so that the pool water is transported to the diverter plate 1101 by the water pump 17, and then the water is distributed to the high-pressure nozzle 1102 through the diverter plate 1101. Through the high-pressure nozzle 1102, the high-pressure nozzle 1102 flushes the sludge above the filter screen 1103, so that the sludge is decomposed;

[0045] A filter screen 1103 is fixedly connected to the inner wall of the treatment box 11, and a sediment separation plate 1104 is provided on the inner wall of the treatment box 11. The sediment separation plate 1104 is made of an activated carbon plate. A polymer plate 1105 is fixedly connected to the inner bottom wall of the treatment box 11, and the angle between the polymer plate 1105 and the bottom of the treatment box 11 is 30 degrees. A sewage pipe 1106 is fixedly connected to the inner bottom wall of the polymer plate 1105.

[0046] As a result, the silt passes through the filter 1103 and falls into the silt separation plate 1104, and the silt is separated by the silt separation plate 1104, so that the sludge passes through the silt separation plate 1104 and falls into the aggregation plate 1105. Since the angle between the aggregation plate 1105 and the bottom of the treatment box 11 is 30°, the sludge completely falls into the sewage pipe 1106, and the decomposed sludge is transported through the sewage pipe 1106, which makes it convenient for users to collect recyclable materials contained in the sludge, improves the sludge recovery effect, and increases the practicality of the overall device.

[0047] The specific implementation method is as follows: through the silt treatment mechanism component 3 and the silt shovel 14, it is convenient for users to quickly clean the silt at the bottom of the water conservancy project, prevent the telescopic sludge pipe 4 from being blocked due to the large silt body, ensure the stability of silt transportation, and improve the service life of the silt treatment device. At the same time, it is convenient for users to drive the silt shovel 14 for adjustment, ensure the stability of the silt shovel 14 in treating the silt, prevent the silt from staying in the silt shovel 14, ensure the efficiency of the silt shovel 14 in removing the bottom silt, and increase the stability of the overall device in treating the silt.

[0048] The working principle of the present invention is as follows: when the user needs to ensure that silt is removed from water conservancy projects at different depths, the user starts the retractable mechanism assembly 2 to unwind the No. 1 wire steel 204. Since the weight of the silt handling mechanism assembly 3 and the silt shovel plate 14 is too large, the silt handling mechanism assembly 3 and the silt shovel plate 14 sink. When the silt handling mechanism assembly 3 and the silt shovel plate 14 sink, the telescopic sludge pipe 4 drives the sliding ring 6 to rotate along the No. 2 adjusting rod 7 through the conveying box 5, thereby adjusting the angle of the telescopic sludge pipe 4 until the silt handling mechanism assembly 3 stretches the telescopic sludge pipe 4 until the silt shovel plate 14 After the sludge is lowered to the bottom of the pool, the hull 1 is started, and the hull 1 drives the silt shovel 14 to move along the bottom, so that the silt shovel 14 shovels the silt at the bottom, causing the silt to fall into the silt shovel 14. Then, the sludge pump 10 is started, so that the suction force of the sludge pump 10 is transported to the telescopic sludge pipe 4 through the No. 1 delivery pipe 8. Since the telescopic sludge pipe 4 and the No. 2 delivery pipe 16 are installed on both sides of the sludge treatment mechanism assembly 3, the No. 2 delivery pipe 16 extracts the silt in the silt shovel 14 through the sewage trough 15 opened on the inner wall of the silt shovel 14, so that the silt is transported to the sludge treatment mechanism assembly 3 through the No. 2 delivery pipe 16.

[0049] The silt treatment mechanism assembly 3 is then started to crush the large pieces of silt, and at the same time, the connecting plate 12 fixed on the outer wall of the No. 1 fixed rod 308 rotates together. Since the inner wall of the connecting plate 12 is fixedly connected to the No. 2 fixed rod 13, and the outer wall of the No. 2 fixed rod 13 is fixedly connected to the silt shovel plate 14, the silt shovel plate 14 is rotated following the No. 1 fixed rod 308 through the connecting plate 12, so that the angle of the silt shovel plate 14 is adjusted, so that the silt in the silt shovel plate 14 enters the sewage trough 15 through fluidity, completing the treatment of the bottom silt, and the silt is transported to the treatment box 11 through the conveying box 5 and the No. 1 conveying pipe 8. The stability of the silt transportation is ensured by the limit frame 9. When the silt enters the treatment box 11, the water pump 17 is started, and the water pump 17 extracts the water in the pool through the extraction pipe 18, so that the pool water is transported to the treatment box 11 through the water pump 17, and then the decomposed silt is transported through the treatment box 11.
