[0002] Rural water conservancy projects refer to dikes built in rural areas to intercept the flow of water from rivers, lakes and valleys, serving functions such as water storage, flood control and irrigation. Maintenance equipment refers to the equipment and tools specifically used for the daily inspection, maintenance and protection of such dikes. During the off-season before spring plowing, maintenance personnel operate portable dike leakage detectors to check for small cracks and weed growth on a certain section of the dike slope in real time.

[0003] In existing technologies, some maintenance devices are equipped with leakage detection modules that use probes to contact the dam surface and utilize ultrasonic and resistance sensing technologies to convert the internal structural signals of the dam into electrical signals. After analysis by the built-in processor, the system determines whether there are seepage channels and loose areas, and provides real-time feedback to the operators.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] A maintenance device for rural water conservancy project embankments, referring to Figures 1 to 3 The system includes a connecting seat 1, which has high-strength support performance and serves as the installation base for various functional modules, enabling the coordinated operation of different mechanisms. The connecting seat 1 is externally fixedly connected to a disassembly mechanism 2, which is used for clearing weeds from the embankment and quickly replacing parts. The connecting seat 1 is internally fixedly connected to a compaction mechanism 3, which compacts the loose soil on the embankment slope. The disassembly mechanism 2 includes a weeding component 21, which is externally fixedly connected to the connecting seat 1 to ensure stability during operation and prevent parts from loosening due to vibration. The weeding component 21 is externally fixedly connected to multiple rotating plates 22, which fix the connection structure and transmit rotational power, so that the connection structure can rotate at high speed with the rotating plates 22 to cut weeds. Each rotating plate 22 is externally fixedly connected to a blade 23, which has the characteristics of high sharpness and wear resistance, and can effectively cut the stems of weeds on the embankment surface and prevent weed roots from damaging the soil structure of the embankment.

[0034] Specifically, the high-strength support connecting seat 1 serves as a stable installation base, ensuring the coordinated operation of each functional module. Its external disassembly mechanism 2, through the weeding component 21 combined with the high-speed rotating plate 22 and the high-sharp wear-resistant blade 23, can efficiently cut the stems of weeds on the embankment, preventing the roots of weeds from damaging the soil structure of the embankment, and facilitating the quick replacement of components. The internal compaction mechanism 3 can specifically compact the loose soil on the embankment slope. The cooperation of multiple mechanisms realizes the dual functions of weed removal and soil reinforcement, effectively improving the maintenance effect and stability of the embankment, and ensuring the safety of the embankment in rural water conservancy projects.

[0035] The blade 23 has two external sliding posts 24 internally connected, facilitating quick disassembly and installation of the blade 23 via a locking mechanism. Each external sliding post 24 has two grooves 25 inside, which limit the movement of the internal structure and prevent it from moving freely when not in operation. Each groove 25 has a slidingly connected retaining ball 26, which has high strength. When the retaining ball 26 extends out of the groove 25 and engages with the corresponding opening in the rotating plate 22, the external sliding post 24 and the rotating plate 22 can be fixed together. The blade 23 is installed and fixed. When the retaining ball 26 is retracted into the groove 25, the outer slide column 24 can slide freely, which facilitates the disassembly of the blade 23. The inner slide column 27 is slidably connected inside the outer slide column 24 and slides smoothly inside the outer slide column 24. The movement of the inner slide column 27 drives the subsequent components to move, thereby controlling the state of the retaining ball 26. The top of the inner slide column 27 is fixedly connected to the handle 28, and the surface is provided with anti-slip texture to increase the friction between the hand and the handle 28, making it convenient for the operator to drive the inner slide column 27 to slide up and down by lifting and pressing the handle 28.

[0036] Specifically, the outer sliding column 24 works in conjunction with the inner sliding column 27. The state of the locking ball 26 can be controlled by lifting and pressing the handle 28. When the locking ball 26 extends out of the groove 25 and is inserted into the opening of the rotating plate 22, it can securely fix the blade 23. When it is retracted, it is easy to disassemble the blade 23, achieving quick disassembly and assembly. The groove 25 limits the internal structure and prevents it from moving randomly when not in operation. The anti-slip texture of the handle 28 increases friction and makes it easier for the operator to exert force. The overall structure ensures that the blade 23 is easy to disassemble and reliably fixed, reducing the time and difficulty of replacing parts during maintenance operations and improving the efficiency of dam maintenance.

[0037] A spring a29 is fixedly connected to the bottom of the inner sliding column 27. When the inner sliding column 27 is pressed down, the spring a29 is compressed and stores elastic potential energy. After the handle 28 is released, the spring a29 can drive the inner sliding column 27 to move upward through elastic reset and return to the initial position. A push plate 210 is fixedly connected to the bottom of the spring a29 to transmit the elastic force of the spring a29 and push the bottom structure to move. Two pressure balls 211 are slidably connected inside the outer sliding column 24. When the push plate 210 presses the pressure balls 211 downward, the pressure balls 211 will move towards the groove 25 and press the locking ball 26, so that the locking ball 26 extends out of the groove 25, thereby realizing the engagement of the outer sliding column 24 with the rotating plate 22. When the push plate 210 moves upward, the pressure balls 211 no longer press the locking ball 26, and the locking ball 26 retracts into the groove 25 under the pressure of the opening of the rotating plate 22, releasing the engagement state.

[0038] Specifically, the spring a29 at the bottom of the inner sliding column 27 stores elastic potential energy when pressed and drives the inner sliding column 27 to reset when released, providing power for the structural movement. The push plate 210 can effectively transmit the elastic force of the spring a29, pushing the pressure ball 211 to move. When the pressure ball 211 is squeezed, it can push the locking ball 26 out of the groove 25, so that the outer sliding column 24 and the rotating plate 22 can be engaged to fix the blade 23. When the push plate 210 moves upward, the pressure ball 211 no longer applies pressure, and the locking ball 26 can be retracted to release the engagement. The overall structure drives the coordinated movement of each component through the elastic force of the spring a29, without complicated operation. This ensures the stability of the blade 23 when it is fixed and makes disassembly more convenient, further improving the efficiency of blade 23 disassembly and assembly and reducing the difficulty of dam maintenance operations.

[0039] The rotating plate 22 is internally fixedly connected to two fixing blocks 212. Each fixing block 212 has a slot 213 on its outside to accommodate the retaining bead 26 and to position the outer sliding column 24. The outside of each retaining bead 26 is slidably connected to the inside of the slot 213. By engaging and disengaging the retaining bead 26 with the slot 213, the blade 23 and the rotating plate 22 can be detachably connected. This facilitates quick replacement of the blade 23 after it wears out, without disassembling the entire rotating plate 22, which greatly improves maintenance efficiency. The outside of the handle 28 is slidably connected to the outside of the outer sliding column 24, and the outside of the push plate 210 is slidably connected to the inside of the outer sliding column 24. This ensures that the push plate 210 remains horizontal during movement and prevents the push plate 210 from tilting, which would cause uneven force on the two pressure beads 211 and thus affect the extension and retraction effect of the retaining bead 26. The tops of the two pressure beads 211 contact the bottom of the push plate 210.

[0040] Specifically, the fixing block 212 and slot 213 inside the rotating plate 22 can accommodate the retaining bead 26 to position the outer sliding column 24. The blade 23 and the rotating plate 22 are detachably connected by engaging and disengaging. After the blade 23 wears out, it can be quickly replaced without disassembling the entire rotating plate 22, which greatly improves maintenance efficiency. The connection method of the handle 28 sliding outward and the push plate 210 sliding inward can ensure that the push plate 210 remains horizontal when moving, avoiding uneven force on the pressure bead 211 due to the tilt of the push plate 210, thereby ensuring the stable extension and retraction effect of the retaining bead 26, making the disassembly and assembly of the blade 23 more reliable, and further helping to carry out dam maintenance operations efficiently.

[0041] The weeding assembly 21 includes a housing 2101, which is fixedly connected to the outside of the connecting base 1. The housing 2101 protects the internal components and provides a mounting base. A motor a2102 is fixedly connected to the outside of the housing 2101. An electric shaft 2103 is fixedly connected to the drive end of the motor a2102. The electric shaft 2103 is rotatably connected to the inside of the housing 2101. Multiple rotating plates 22 are fixedly connected to the outside of the electric shaft 2103 and rotatably connected to the inside of the housing 2101. Multiple blades 23 are rotatably connected to the inside of the housing 2101. The area of ​​the bottom opening of the housing 2101 matches the projected area of ​​the rotation trajectory of the blades 23, which ensures that the blades 23 can smoothly contact and cut the weeds on the embankment surface, and also prevents weed debris from splashing into the inside of the housing 2101 and affecting the normal operation of the motor a2102 and the electric shaft 2103.

[0042] Specifically, the outer casing 2101 not only protects the internal components but also provides a stable mounting base for the motor a2102, the electric shaft 2103, etc. The motor a2102 drives the electric shaft 2103 to rotate, which can drive the rotating plate 22 and the blade 23 to rotate synchronously, efficiently completing the weed cutting. At the same time, the bottom opening area of ​​the outer casing 2101 matches the projection of the rotation trajectory of the blade 23, ensuring that the blade 23 can smoothly contact the weeds on the embankment and preventing weed debris from splashing into the interior, avoiding affecting the operation of the motor a2102 and the electric shaft 2103, ensuring stable and efficient weeding operations, and providing reliable support for the weed clearing stage of embankment maintenance.

[0043] Reference Figure 4 and Figure 5 The compaction mechanism 3 includes two motors b31, which are externally fixedly connected to the inside of the connecting seat 1. The drive end of each motor b31 is fixedly connected to a rotating shaft 32 for transmitting power. The external of the rotating shaft 32 is rotatably connected to a track assembly 33. The track assembly 33 consists of track plates, track chains, and guide wheels. The track plates are made of high-elasticity rubber material with diamond-shaped anti-slip patterns on the surface, which can increase the friction with the soil on the embankment slope and prevent the device from slipping during walking and compaction operations. The guide wheels can adjust the tension of the track to ensure that the track assembly 33 remains stable during movement and prevent the track from falling off.

[0044] Specifically, in the compaction mechanism 3, the motor b31 is the core power source, which efficiently transmits power through the rotating shaft 32 to drive the track assembly 33 to operate. The track plates are made of high-elasticity rubber material, with diamond-shaped anti-slip patterns on the surface, which can greatly increase the friction with the soil on the embankment slope and effectively prevent the device from slipping during walking and compaction operations. The guide wheels can flexibly adjust the track tension to ensure that the track assembly 33 is always stable during movement and to prevent the track from falling off. The overall structure ensures the safety and stability of the device when operating on the embankment slope, provides reliable support for the compaction of loose soil, and helps to improve the quality of embankment maintenance.

[0045] The bottom of the connecting seat 1 is fixedly connected to a top clamping plate 34, which can bear the weight of the telescopic rod 35 and subsequent compaction components, preventing the top clamping plate 34 from deforming and breaking during operation. The bottom of the top clamping plate 34 is rotatably connected to the telescopic rod 35, which is convenient to adapt to the slope changes of the dam slope and ensures that the subsequent structure can always remain perpendicular to the dam slope, thereby improving the compaction effect. The bottom of the telescopic rod 35 is fixedly connected to an outer frame 36, which has the characteristics of being lightweight and high-strength, reducing the weight of the entire compaction mechanism 3 and making it easy for the telescopic rod 35 to drive it up and down. At the same time, it can withstand the impact force generated during vibration compaction. The top of the outer frame 36 is fixedly connected to a clamping plate 37, which is convenient to connect the bottom structure to rotate. The inside of the clamping plate 37 is rotatably connected to a connecting rod 38, which has good toughness and strength and can transmit the vibration power of the connecting structure to the outer frame 36. At the same time, it can rotate flexibly around the pin of the clamping plate 37 to adapt to the angle changes when the connecting mechanism vibrates up and down, avoiding rigid collisions.

[0046] Specifically, the top clamping plate 34 at the bottom of the connecting seat 1 can stably support the weight of the telescopic rod 35 and the compaction components, preventing deformation and breakage. The telescopic rod 35 can flexibly adapt to the slope of the dam, ensuring that the subsequent structure is perpendicular to the slope and improving the compaction effect. The outer frame 36 is lightweight and high-strength, which not only reduces the weight of the compaction mechanism 3 for easy lifting and lowering, but also withstands vibration and impact. The clamping plate 37 facilitates the rotation of the bottom structure. The connecting rod 38 has excellent toughness and strength, can transmit vibration power, and can also flexibly rotate around the pin to adapt to changes in vibration angle, avoiding rigid collisions. Overall, it ensures stable and efficient compaction operations.

[0047] A protective block 39 is fixedly connected to the bottom of the connecting rod 38. It has high wear resistance and impact resistance and protects the bidirectional motor fixedly connected inside. A connecting shaft 310 is rotatably connected inside the protective block 39. Two centrifugal blocks 311 are fixedly connected to the outside of the connecting shaft 310. When the connecting shaft 310 drives the centrifugal blocks 311 to rotate at high speed, the centrifugal blocks 311 will generate periodically changing centrifugal force. This centrifugal force drives the protective block 39 to vibrate up and down, providing power for the compaction operation. Two sliding shafts 312 are fixedly connected to the outside of the protective block 39 to guide the vibration direction. A spring b313 is respectively sleeved on the outside of each sliding shaft 312, which has high elastic limit and fatigue strength to increase the compaction force. A pressure plate 314 is fixedly connected to the bottom of the outer frame 36 for directly compacting the soil. The outside of the protective block 39 is fixedly connected to the adjacent side of the two sliding shafts 312. The outside of each sliding shaft 312 is slidably connected to the inside of the outer frame 36. The outside of the sliding shaft 312 is slidably connected to the inside of the connecting seat 1.

[0048] Specifically, the protective block 39 at the bottom of the connecting rod 38 is wear-resistant and impact-resistant to protect the internal bidirectional motor. The connecting shaft 310 drives the centrifugal block 311 to rotate at high speed to generate periodic centrifugal force, providing power for the compaction operation. The sliding shaft 312 can guide the vibration direction. The spring b313 increases the compaction force with its high elastic limit and fatigue strength. The pressure plate 314 directly contacts the soil to complete the compaction. The sliding shaft 312 slides inside the outer frame 36 and the connecting seat 1 to ensure structural stability, thus improving the overall soil compaction effect of the dam slope.

[0049] The implementation principle of this application embodiment is as follows: The starting motor a2102 drives the electric shaft 2103 to rotate, which drives the rotating plate 22 and the blade 23 to rotate at high speed. The high sharpness and wear resistance of the blade 23 are used to cut the stems of weeds on the embankment to achieve weeding. When replacing the blade 23, the handle 28 is pulled to move the inner sliding column 27 upward, the spring a29 is reset, the push plate 210 no longer squeezes the pressure ball 211, and the locking ball 26 is squeezed by the groove 213 of the rotating plate 22 and retracts into the groove 25 of the outer sliding column 24. The outer sliding column 24 can slide, so the old blade 23 can be removed. When installing the new blade 23, the handle 28 is pressed to move the inner sliding column 27 downward, the push plate 210 squeezes the pressure ball 211 to push the locking ball 26 out and into the groove 213, and fixes the outer sliding column 24 and the rotating plate 22 to complete the replacement. This avoids the problem of reduced weeding efficiency due to the wear of the blade 23, prevents the roots of weeds from continuously damaging the soil structure of the embankment, and ensures the maintenance effect of the embankment.

[0050] The starting motor b31 drives the track assembly 33 to rotate via the rotating shaft 32, moving the device on the embankment slope. At the same time, the bidirectional motor in the starting protective block 39 drives the connecting shaft 310 to drive the centrifugal block 311 to rotate at high speed, generating periodic centrifugal force, causing the protective block 39 to vibrate up and down. The vibration force is transmitted and amplified by the sliding shaft 312 and the spring b313, and finally the soil is compacted by the pressure plate 314. The telescopic rod 35 can adapt to the slope of the slope to ensure that the pressure plate 314 is perpendicular to the soil, improve the compaction effect, enhance the density of the soil on the embankment slope, prevent rainwater infiltration from causing soil loosening and loss, reduce the risk of embankment collapse, and suppress weed growth, ensuring the structural stability of the embankment and the safety of the water conservancy project.

[0051] 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.
