Description

Technical Field

[0001] The utility model relates to silt clearing equipment used in water conservancy project construction, belonging to the technical field of water conservancy project construction. Background Art

[0002] Hydraulic engineering is an engineering discipline that deals with the management and development of water resources. Its main purpose is to optimize the use and conservation of water resources to support agriculture, industry, residential water use and environmental protection. Such projects usually include the design and construction of reservoirs, dams, channels, pumping stations, flood control systems and irrigation systems. Through hydraulic engineering, floods can be effectively controlled, a stable water supply can be provided, agricultural productivity can be increased, and energy can be provided to communities through hydroelectric power generation.

[0003] A Chinese public patent (publication number: CN 216810077 U) discloses a river channel dredging equipment used in water conservancy project construction, including a main body, a collecting trough is provided on the outer surface of the main body, a second fixed rod is fixedly connected to the inner wall of the collecting trough, a motor is provided on the outer surface of the second fixed rod, a rotating column is fixedly connected to the output end of the motor, a stirring blade is fixedly connected to the outer surface of the rotating column, a separation plate is movably connected to the inner wall of the collecting trough, a sealing ring is fixedly connected to the outer surface of the separating plate, and the end of the rotating column away from the motor is movably connected to the inside of the sealing ring, and a water storage tank is provided below the separating plate.

[0004] However, there are often a lot of garbage and stones in the silt. When the silt is being dredged, the stones may be sucked into the silt extraction pump simultaneously with the silt, causing the parts in the silt extraction pump to be damaged by the stones, thereby affecting the normal dredging work. At the same time, the silt often has a certain thickness. When the dredging device itself is not convenient for height adjustment, the dredging device may only be able to dredge the surface of the silt, and the deeper parts cannot be dredged due to the inability to contact, thereby reducing the dredging efficiency.

[0005] Therefore, a dredging device for water conservancy project construction is proposed. Utility Model Content

[0017] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0018] 1. The utility model provides a lifting device. When it is necessary to dredge a deeper part, the bidirectional screw is rotated through the output of the first motor. At this time, the screw block moves inward along the surface of the bidirectional screw due to the rotation of the bidirectional screw. As the screw block moves, the first clamping plate moves inward synchronously and causes the connecting rod to flip inward. As the connecting rod flips, the second clamping plate and the dredging bucket are pushed downward, so that the dredging bucket moves downward as a whole, thereby completing the dredging of silt in a deeper part and avoiding the situation that the silt thickness is deep and the dredging bucket does not have the function of adjusting the height. The dredging bucket can only dredge the surface layer of silt, which reduces the dredging efficiency and affects the normal dredging work. By providing a crushing device, when the silt extraction pump draws in the silt, By filtering through the filter net, larger stones can be filtered to prevent the stones from entering the inner cavity of the dredging barrel. Then, smaller stones and silt enter the inner cavity of the cavity through the filter net. Then, the output end of the second motor drives the active crushing rod to rotate. At this time, the driven crushing rod is engaged with the active crushing rod, and the driven crushing rod rotates synchronously to crush smaller garbage or stones. The crushed stones, garbage and silt enter the inner cavity of the installation cavity through the infiltration hole, completing the crushing of stones and garbage in the silt, preventing garbage and stones from entering the interior of the silt extraction pump, which would cause blockage of the silt extraction pump or damage to internal parts. This increases the service life of the silt extraction pump and reduces the problem of reduced dredging efficiency due to damage to the silt extraction pump.

[0019] Second, the utility model can limit the moving direction of the screw block by setting a limit rod, so as to prevent the screw block from rotating synchronously due to the rotation of the bidirectional screw rod, thereby affecting the lifting and lowering of the silt removal bucket. By setting a self-tapping bolt, the filter screen can be easily disassembled and replaced, so as to prevent the filter opening in the filter screen from becoming larger due to the collision of stones after long-term use, thereby affecting the filtering work of large stones. By setting a waterproof cover, the second motor can be protected to prevent silt or river water from entering the interior of the second motor, thereby causing damage to the components in the second motor. By setting a sealing ring, it can be further The sealing effect of the waterproof cover on the second motor is further improved to prevent the second motor from being damaged due to the influence of silt or river water, which in turn affects the crushing of garbage or small stones in the silt. By setting the oblique blade, the silt removal bucket can be easily inserted into the silt when moving downward due to the oblique angle, thereby facilitating the silt removal work at a deeper level. By setting the silt extraction pipe and the flange, it can be conveniently connected to the silt collecting device, thereby facilitating the collection of the silt. By setting the fixing bolts, the overall equipment can be easily installed or disassembled, and can be conveniently installed in different positions according to usage requirements.

DETAILED DESCRIPTION

[0029] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0030] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figure 1-6 As shown, the embodiment of the utility model provides a dredging device for water conservancy project construction, including a dredging bucket 1, a mounting cavity 5 is provided at the bottom of the dredging bucket 1, a cavity 4 is provided on the inner surface of the top of the dredging bucket 1, a dredging pump 6 is fixedly installed on the top of the dredging bucket 1, and a second ring 14 is fixedly installed in the inner cavity of the mounting cavity 5;

[0033] A lifting device 2 is provided on the top of the dredging bucket 1. The lifting device 2 includes a mounting frame 201, which is provided on the top of the dredging bucket 1. A first motor 202 is fixedly installed on the left side of the mounting frame 201. A bidirectional screw 203 is fixedly connected to the output end of the first motor 202. Screw blocks 204 are threadedly connected to the left and right sides of the surface of the bidirectional screw 203. First clamping plates 205 are fixedly installed on the left and right sides of the bottom of the two screw blocks 204. Connecting rods 206 are movably connected to the inner sides of the two first clamping plates 205. The bottoms of the two connecting rods 206 are movably connected to second clamping plates 207. The bottoms of the two second clamping plates 207 are fixedly installed on the left and right sides of the top of the dredging bucket 1.

[0034] A crushing device 3 is arranged in the inner cavity of the cavity 4, and the crushing device 3 includes a second motor 301, and the second motor 301 is fixedly installed at the bottom of the inner cavity of the cavity 4, and the output end of the second motor 301 is fixedly connected with an active crushing rod 302, and the top of the inner cavity of the installation cavity 5 is movably connected with a driven crushing rod 303, and the inner sides of the five driven crushing rods 303 are meshed with the outer sides of the active crushing rod 302, and a first ring 304 is arranged in the inner cavity of the installation cavity 5, and a filter net 305 is fixedly installed on the inner side of the first ring 304, and penetration holes 307 are opened around the bottom of the inner cavity of the cavity 4.

[0035] By setting the lifting device 2, when it is necessary to dredge the deeper part, the bidirectional screw 203 is rotated through the output of the first motor 202. At this time, the screw block 204 moves inward along the surface of the bidirectional screw 203 due to the rotation of the bidirectional screw 203. With the movement of the screw block 204, the first clamping plate 205 moves inward synchronously and causes the connecting rod 206 to flip inward. With the flipping of the connecting rod 206, the second clamping plate 207 and the dredging bucket 1 are pushed downward, so that the dredging bucket 1 moves downward as a whole, thereby completing the dredging of the silt in the deeper part and avoiding the silt thickness being too deep. When the dredging bucket 1 does not have the function of adjusting the height, the dredging bucket 1 can only dredge the surface layer of the silt, which leads to a decrease in the dredging efficiency and affects the normal dredging work. By setting the crushing device 3, when the silt extraction pump 6 draws the silt in, By filtering through the filter net 305, larger stones can be filtered to prevent the stones from entering the inner cavity of the silt removal barrel 1. Then, smaller stones and silt enter the inner cavity of the cavity 4 through the filter net 305. Then, the output end of the second motor 301 drives the active crushing rod 302 to rotate. At this time, the driven crushing rod 303 is engaged with the active crushing rod 302, and the driven crushing rod 303 rotates synchronously to crush smaller garbage or stones. The crushed stones, garbage and silt enter the inner cavity of the installation cavity 5 through the penetration hole 307, completing the crushing of stones and garbage in the silt, preventing garbage and stones from entering the interior of the silt extraction pump 6, and then causing the silt extraction pump 6 to be blocked or the internal parts to be damaged, thereby improving the service life of the silt extraction pump 6 and reducing the problem of reduced dredging efficiency due to damage to the silt extraction pump 6.

[0036] Example 2

[0037] In one embodiment, a limit rod 208 is fixedly installed on the top of the inner side of the mounting frame 201, the inner surfaces of the two screw blocks 204 are slidably connected to the surface of the limit rod 208, the bottom of the first ring 304 is threadedly connected with a self-tapping bolt 306, and the tops of the six self-tapping bolts 306 are threadedly connected to the bottom of the second ring 14, a waterproof cover 12 is provided on the outside of the second motor 301, and the waterproof cover 12 is fixedly installed on the middle end of the top of the inner cavity of the cavity 4, and a sealing ring 13 is fixedly installed on the bottom of the inner cavity of the cavity 4, and the inner side of the sealing ring 13 is in contact with the outer side of the waterproof cover 12, and an oblique knife edge 11 is fixedly installed on the bottom of the dredging bucket 1, and the vertical angle of the oblique knife edge 11 is forty-five degrees, the output end of the silt extraction pump 6 is connected to the silt extraction pipe 7, and the end of the silt extraction pipe 7 away from the silt extraction pump 6 is fixedly installed with a flange 8, and the left and right sides of the top of the lifting device 2 are fixedly installed with fixing plates 9, and the front and rear sides of the bottom of the two fixing plates 9 are threadedly connected with fixing bolts 10.

[0038] By setting the limit rod 208, the moving direction of the screw block 204 can be limited to prevent the screw block 204 from rotating synchronously due to the rotation of the bidirectional screw rod 203, thereby affecting the lifting and lowering of the dredging bucket 1. By setting the self-tapping bolt 306, the filter screen 305 can be easily disassembled and replaced to prevent the filter opening in the filter screen 305 from becoming larger due to the collision of stones after long-term use, thereby affecting the filtering work of large stones. By setting the waterproof cover 12, the second motor 301 can be protected to prevent silt or river water from entering the interior of the second motor 301, thereby causing damage to the components in the second motor 301. By setting the sealing ring 1 3, the sealing effect of the waterproof cover 12 on the second motor 301 can be further improved, so as to prevent the second motor 301 from being damaged due to the influence of silt or river water, thereby affecting the crushing of garbage or small stones in the silt. By setting the oblique blade 11, due to its oblique angle, the dredging bucket 1 can be easily inserted into the silt when moving downward, thereby facilitating the dredging of deeper silt. By setting the silt extraction pipe 7 and the flange 8, it can be conveniently connected to the silt collecting device, thereby facilitating the collection of silt. By setting the fixing bolts 10, the overall equipment can be easily installed or disassembled, and can be conveniently installed in different positions according to the use requirements.

[0039] When the utility model is working: when the silt extraction pump 6 draws in the silt, the larger stones can be filtered through the filtration of the filter screen 305 to prevent the stones from entering the inner cavity of the silt removal bucket 1, and then the smaller stones and silt enter the inner cavity of the cavity 4 through the filter screen 305, and then the output end of the second motor 301 drives the active crushing rod 302 to rotate, and at this time the driven crushing rod 303 is meshed with the active crushing rod 302, and the driven crushing rod 303 rotates synchronously and crushes the smaller garbage or stones, and the crushed stones, garbage and silt enter the inner cavity of the installation cavity 5 through the penetration hole 307 , completing the crushing of stones and garbage in the silt. At this time, the surface silt is dredged, and then the bidirectional screw 203 rotates through the output of the first motor 202. At this time, the screw block 204 moves inward along the surface of the bidirectional screw 203 due to the rotation of the bidirectional screw 203. As the screw block 204 moves, the first clamping plate 205 moves inward synchronously and causes the connecting rod 206 to flip inward. As the connecting rod 206 flips, the second clamping plate 207 and the dredging bucket 1 are pushed downward, causing the dredging bucket 1 to move downward as a whole, thereby completing the dredging of the silt in deeper parts.

[0040] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
