Description

Technical Field

[0001] The invention relates to the technical field of water conservancy project maintenance equipment, in particular to a cleaning device for water conservancy project maintenance. Background Art

[0002] In the daily maintenance of water conservancy projects, cleaning the bottom of water conservancy facilities such as rivers and channels is a key task. As time goes by, a large amount of silt, aquatic plants, garbage and other debris will accumulate at the bottom of water conservancy facilities. The accumulation of these materials will not only reduce the water flow section of water conservancy facilities, affect the smoothness of water flow, reduce the water delivery and flood discharge capacity of water conservancy facilities, but also may cause water quality deterioration, ecological damage and other problems.

[0003] At present, there are many deficiencies in the existing water conservancy project maintenance and cleaning devices on the market. Most common cleaning equipment has a relatively simple structure. During the cleaning process, some cleaning devices based on the bucket principle have difficulty in accurately adjusting the cleaning depth according to the real-time changes in the terrain due to the complex and changeable terrain at the bottom of the water conservancy facilities, with ups and downs and unevenness. When the bucket is set at a high height, it is impossible to thoroughly clean up the silt, aquatic plants and other materials at the bottom, and it is easy to leave a large amount of residue, affecting the cleaning effect. On the contrary, if the bucket is set at a low height, when encountering the raised part at the bottom, a collision will occur, and the equipment may even be damaged, and the bucket height needs to be adjusted manually frequently, which not only increases the workload of the operator, but also greatly reduces the efficiency of the cleaning work.

[0013] Preferably, one end of the sewage suction pipe passes through the shell and is arranged above the bucket, and a sewage discharge pipe is fixedly arranged at the output end of the pump, and one end of the sewage discharge pipe is arranged on the outer wall of the shell.

[0014] A method for using a cleaning device for water conservancy project maintenance comprises the following steps: S1. Preparation work: survey the area to be cleaned up in the water conservancy project, check the connection and integrity of each component of the device, ensure that the battery power is normal, and set the pressure sensor threshold in the control system according to the debris situation; S2, cleaning operation; start motor 2 to drive the cleaning mechanism to break loose debris; start motor 1, so that the top rod drives the bucket to scoop up debris and separate it through the screen under the feedback of the pressure sensor; start the mobile mechanism drive device to move and clean according to the route; start the pump to collect and discharge sludge and sewage through the suction pipe and the discharge pipe; S3. After the cleaning is completed, all components are shut down and stopped from running, and the device is removed for storage, and the cleaning materials are subsequently processed and the device is cleaned and maintained.

[0015] Working principle: After motor 2 is started, it converts electrical energy into mechanical energy, drives gear 2 to rotate through the coupling, and rotates gear 1 and the drill rod and spiral blades connected to it through gear transmission. The spiral blades break and loosen the silt, aquatic plants and other debris on the bottom of the water, changing their compacted state to facilitate subsequent cleaning.

[0016] Then, the motor 1 drives the cam to rotate, and the shaft 1 drives the push rod to reciprocate up and down. The pressure sensor at the bottom of the push rod monitors the pressure on the bucket in real time and transmits the signal to the control system. The control system adjusts the motor 1 or the push rod stroke according to the preset threshold and the received signal, so that the bucket can adaptively shovel the debris according to the terrain and debris conditions under the cooperation of the spring. The shoveled debris is initially separated by the screen plate, and the larger debris is intercepted and the small particles fall down.

[0017] At the same time, the moving mechanism relies on the transmission shaft to transmit power to drive the driving wheel to rotate. The driving wheel drives the crawler track to rotate by virtue of the engagement with the transmission teeth on the inner wall of the crawler track. Under the guidance of the guide wheel, the load-bearing wheel and the anti-slip effect of the anti-slip strip on the outer wall of the crawler track, the device can move stably and flexibly at the bottom of the water conservancy project along the predetermined route to ensure comprehensive cleaning coverage.

[0018] Finally, the pump of the sewage discharge mechanism is started under the power of the battery, and the internal impeller rotates to generate suction. The silt, sewage, etc. under the bucket are sucked into the pump through the sewage suction pipe under the action of pressure difference, and then discharged to the designated location through the sewage pipe, thereby collecting and discharging the cleaned pollutants to avoid accumulation that affects the operation.

[0019] The various mechanisms of the entire device complement each other. Through the above-mentioned working principle, it effectively solves the problems faced by traditional cleaning devices, such as difficult cleaning of debris, poor terrain adaptability, and inconvenient sewage discharge, thereby achieving high-quality and efficient maintenance and cleaning work for water conservancy projects.

[0020] The present invention provides a cleaning device for water conservancy project maintenance, which has the following beneficial effects: 1. The present invention uses a pressure sensor to monitor pressure changes in real time and dynamically adjusts the control system. The bucket can automatically adjust its fit with the bottom surface according to the actual terrain fluctuations at the bottom of the water conservancy project, ensuring comprehensive and effective cleaning of aquatic plants, silt and other debris. This solves the problem that the cleaning device cannot adapt to the terrain.

[0021] 2. The present invention drives the drill rod and the spiral blade to rotate through the gear transmission driven by the second motor, which can effectively break up the condensed and compacted silt at the bottom of the water conservancy project and turn it into loose small particles. At the same time, it can also separate and break up the water plants and other debris that are entangled and tangled with each other, making the state of various debris more conducive to subsequent bucket collection and cleaning, avoiding the situation where the debris cannot be thoroughly cleaned due to agglomeration and adhesion, and greatly improving the thoroughness of the overall cleaning. Solve the problem of difficulty in cleaning debris.

[0022] 3. Through the structural characteristics of the crawler itself and the auxiliary effects of anti-skid strips, load-bearing wheels and other components, the mobile mechanism of the present invention can adapt well to different bottom terrains of water conservancy projects, such as the bottom of a river covered with silt, the bottom of a reservoir with a certain slope, or a channel with a lot of debris. It can pass smoothly, effectively overcoming the disadvantages of traditional mobile methods that they are easily stuck and unable to move in complex terrains, greatly expanding the scope of application of the cleaning device and ensuring the feasibility of cleaning operations in various water conservancy project environments.

[0023] 4. The present invention, through the suction force generated by the pump and the complete sewage discharge channel formed by the sewage suction pipe and the sewage discharge pipe, can quickly and continuously suck away and discharge pollutants such as silt, sewage and fine debris generated during the cleaning process from the cleaning area at the bottom of the water conservancy project, thereby avoiding the accumulation of these pollutants around the cleaning device and affecting the subsequent cleaning work, greatly improving the efficiency of the entire cleaning operation and ensuring that the cleaning work can be carried out uninterruptedly.

DETAILED DESCRIPTION

[0026] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0027] Please refer to the attached Figure 3 -Attached Figure 4 , Attachment Figure 7 A cleaning device for water conservancy project maintenance comprises a shell 1, a protective shell 2 is arranged on the upper surface of the shell 1, a motor 17 is arranged inside the protective shell 2, the outer wall of the motor 17 is arranged on the upper surface of the shell 1, a cam 18 is fixedly arranged on the output end of the motor 17, a rotating groove is arranged inside the cam 18, a rotating shaft 20 is arranged in the rotating groove of the cam 18, push rods 19 are arranged at both ends of the outer wall of the rotating shaft 20, the outer wall of the push rod 19 penetrates the shell 1 and is provided with a fixing frame 29, a pressure sensor is arranged at the bottom end of 19, a spring 14 is arranged at the bottom end of the push rod 19, a bucket 12 is arranged at the bottom end of the spring 14, the outer wall of the bucket 12 is slidably connected with a baffle 13 through a slide groove, the top end of the baffle 13 is fixedly arranged on the lower surface of the shell 1, one end of the bucket 12 is rotatably connected to one end of the baffle 13 through a rotating shaft 24, a screen plate 16 is arranged on one side of the baffle 13, a plurality of holes are arranged on the outer wall of the screen plate 16, and a cleaning mechanism is arranged on one side of the shell 1.

[0028] Specifically, the motor 17 is installed inside the protective shell 2 on the upper surface of the outer shell 1 as a power source, and its output end is fixedly connected to the cam 18. When the motor 17 is started, it will drive the cam 18 to rotate. A rotating groove is provided inside the cam 18, and a rotating shaft 20 is placed in this rotating groove, and the two ends of the outer wall of the rotating shaft 20 are connected to the push rod 19, and the rotation of the cam 18 can be converted into the up and down reciprocating motion of the push rod 19. The outer wall of the push rod 19 passes through the outer shell 1 and is slidably connected to the fixed frame 29 to provide guidance and stability for the push rod 19. The bottom end of the push rod 19 is provided with a pressure sensor and a spring 14, and the bottom end of the spring 14 is connected to the bucket 12. During the operation of the cleaning device, when the bucket 12 moves along the bottom of the water conservancy project and cleans up debris, it will contact the bottom surface with different terrain conditions, such as uneven areas, places with accumulation of hard blocks and debris, or places with soft soil.

[0029] When the bucket 12 encounters a change in terrain and hits a raised part on the bottom of the water, the upward resistance to the bucket 12 will increase, and this resistance will be transmitted to the spring 14 and the pressure sensor at the bottom of the push rod 19 through the bucket 12. The pressure sensor can accurately detect the change in the pressure value in real time and transmit the pressure signal to the corresponding control system. The control system determines the degree of influence of the current terrain conditions on the bucket 12 based on the received pressure signal and the preset reasonable pressure range parameters. Then, based on the judgment result, the control system can adjust the downward pressure of the bucket 12 and the amplitude of the up and down movement by adjusting the speed and rotation direction of the motor 17 or controlling the stroke of the push rod 19. When the pressure sensor detects excessive pressure, it means that the bucket 12 may have encountered a large protrusion. The control system will appropriately reduce the speed of the motor 17 or reduce the downward pressure of the push rod 19, so that the spring 14 can perform a certain degree of compression buffering, so that the bucket 12 can smoothly pass over the protrusion and avoid damage to the equipment due to forced downward pressure; on the contrary, when encountering a soft soil area with low pressure, the control system can be adjusted accordingly to increase the downward pressure of the bucket 12 appropriately to ensure that the debris can be fully shoveled. At the same time, the outer wall of the bucket 12 is slidably connected to the baffle 13 through a slide groove, the top of the baffle 13 is fixed on the lower surface of the shell 1, and one end of the bucket 12 is rotatably connected to one end of the baffle 13 through the rotating shaft 24. This connection structure provides a multi-dimensional activity space for the bucket 12, making it more flexible and free to adjust its posture according to terrain changes, and further assisting in achieving adaptation to different terrains.

[0030] By real-time monitoring of pressure changes by pressure sensors and dynamic adjustment of the control system, the bucket 12 can automatically adjust its fit with the bottom surface according to the actual terrain fluctuations and height changes at the bottom of the water conservancy project. Whether the bottom surface is relatively flat or has many protrusions and depressions, the bucket 12 can be as close to the bottom surface as possible to ensure comprehensive and effective cleaning of aquatic plants, silt and other debris, greatly improving the thoroughness of cleaning. This solves the problem that the cleaning device cannot adapt to the terrain.

[0031] See attached Figure 1 -Attached Figure 5 The cleaning mechanism includes a motor 2 30, the bottom end of the motor 2 30 is arranged inside the shell 1, a coupling 31 is fixedly arranged at the output end of the motor 2 30, one end of the coupling 31 is fixedly arranged with a gear 22, the tooth ends of both sides of the gear 22 are meshed and connected with the gear 1 21, a drill rod 3 is fixedly arranged in the middle of the gear 1 21, a spiral blade 4 is fixedly arranged on the outer wall of the drill rod 3, and a moving mechanism is arranged on both sides of the shell 1.

[0032] Specifically, when the motor 2 30 is started, the motor 2 30 starts to run, and the coupling 31 fixedly connected to its output end will rotate together with the motor 2 30. The gear 2 22 fixedly set at one end of the coupling 31 starts to make circular motion under the drive of the coupling 31. Since the tooth ends on both sides of the gear 2 22 are respectively meshed with the gear 1 21, according to the gear transmission principle, when the gear 2 22 rotates, the meshed gear 1 21 will be driven and start to rotate in the opposite direction. The drill rod 3 is fixedly set in the middle of the gear 1 21, and the drill rod 3 will rotate synchronously with the rotation of the gear 1 21, and the outer wall of the drill rod 3 is fixedly set with spiral blades 4, and the spiral blades 4 also make circular motion together with the rotation of the drill rod 3. When the entire cleaning mechanism is operating near the bottom of the water conservancy project, the rotating spiral blades 4 will penetrate into the area where silt, aquatic plants and other debris are accumulated.

[0033] The spiral blades 4, by virtue of their spiral structural characteristics and the force generated by rotation, can, on the one hand, cut and stir the relatively compact silt, break the original compact structure of the silt and make it loose; on the other hand, for the entangled aquatic plants and various debris mixed in them, the spiral blades 4 can use the pulling and stirring force generated by rotation to break up and separate the aquatic plants and other debris, so that they no longer stick to each other or are tightly attached to the bottom of the water conservancy project, thereby facilitating the subsequent cleaning work to be carried out smoothly.

[0034] The motor 2 30 drives the gear transmission to drive the drill rod 3 and the spiral blade 4 to rotate, which can effectively break up the condensed and compacted silt at the bottom of the water conservancy project and turn it into loose small particles. At the same time, the water plants and other debris that are entangled and tangled with each other can be separated and scattered, making the state of various debris more conducive to the subsequent bucket 12 to collect and clean up, avoiding the situation where the debris cannot be thoroughly cleaned due to agglomeration and adhesion, and greatly improving the thoroughness of the overall cleaning. Solve the problem of difficulty in cleaning debris.

[0035] See attached Figure 1 -Attached Figure 4 , Attachment Figure 8 The moving mechanism includes a transmission shaft 28, the outer wall of the transmission shaft 28 is arranged inside the shell 1, fixed plates 23 are arranged at both ends of the transmission shaft 28, a driving wheel 7 is arranged on one side of the fixed plate 23, a track 5 is arranged on the outer wall of the driving wheel 7, a plurality of transmission teeth 11 are arranged on the inner wall of the track 5, a plurality of anti-slip strips 6 are arranged on the outer wall of the track 5, a plurality of tooth grooves are arranged on the outer wall of the driving wheel 7, the tooth grooves of the driving wheel 7 are connected to the outer wall of the transmission teeth 11, a fixed plate 10 is arranged at the bottom end of the driving wheel 7, guide wheels 8 are arranged at both ends of the fixed plate 10, the outer wall of the guide wheel 8 is connected to the inner wall of the track 5, a plurality of load-bearing wheels 9 are arranged in the middle of the fixed plate 10, and the load-bearing wheels 9 are arranged on the inner wall of the track 5, and a sewage discharge mechanism is arranged inside the shell 1.

[0036] Specifically, when the power source is started, the transmission shaft 28 starts to rotate. Since the two ends of the transmission shaft 28 are provided with fixed plates 23, and the driving wheel 7 is installed on one side of the fixed plate 23, the rotation of the transmission shaft 28 can drive the driving wheel 7 to rotate synchronously. The outer wall of the driving wheel 7 is provided with a plurality of tooth grooves, and these tooth grooves are meshed and connected with a plurality of transmission teeth 11 provided on the inner wall of the track 5. When the driving wheel 7 rotates, according to the principle of gear transmission, through the bite action of the tooth grooves and the transmission teeth 11, the driving wheel 7 can transmit its own rotational power to the track 5, driving the track 5 to circulate around the driving wheel 7, the guide wheel 8 and the load-bearing wheel 9. In this process, the bottom end of the driving wheel 7 is provided with a fixed plate 10, and the fixed plate 10 plays the role of firmly supporting the driving wheel 7 and carrying other components. Guide wheels 8 are installed at both ends of the fixed plate 10. The outer wall of the guide wheel 8 is tightly connected to the inner wall of the track 5. The main function of the guide wheel 8 is to guide and limit the movement direction of the track 5, ensuring that the track 5 always moves along the preset route during the rotation process, avoiding deviation and the like, and ensuring that the cleaning device can move at the bottom of the water conservancy project according to the established cleaning path. A number of load-bearing wheels 9 are arranged in the middle of the fixed plate 10. The load-bearing wheels 9 are also located on the inner wall of the track 5. They share the weight of the cleaning device as a whole, so that the weight of the device can be evenly distributed on the track 5, reducing the pressure on the track 5 when it contacts the ground, avoiding the problem of the track 5 sinking deeply in the soft bottom of the water conservancy project, and ensuring that the track 5 can operate smoothly under various terrain conditions, further improving the stability of the operation of the entire mobile mechanism. The outer wall of the track 5 is provided with a plurality of anti-skid strips 6, which can increase the friction between the track 5 and the bottom surface of the water conservancy project (whether it is a slippery mud surface or a bottom surface with a certain slope, etc.), prevent slipping during movement, and ensure that the cleaning device can move stably even under complex and harsh terrain conditions, and carry out cleaning operations smoothly.

[0037] Through the structural characteristics of the track 5 itself and the auxiliary effects of components such as the anti-skid strips 6 and the load-bearing wheels 9, the mobile mechanism can adapt well to different bottom terrains of water conservancy projects, such as the bottom of a river channel covered with silt, the bottom of a reservoir with a certain slope, or a channel with a lot of debris. It can pass smoothly, effectively overcoming the disadvantages of traditional mobile methods that they are easily stuck and unable to move in complex terrains, greatly expanding the scope of application of the cleaning device and ensuring the feasibility of cleaning operations in various water conservancy project environments.

[0038] See attached Figure 3 -Attached Figure 4 , Attachment Figure 6The sewage discharge mechanism includes a pump 25, the bottom end of the pump 25 is arranged at the inner bottom end of the shell 1, a battery 27 is arranged on one side of the pump 25, the bottom end of the battery 27 is arranged at the inner bottom end of the shell 1, a sewage suction pipe 26 is fixedly arranged at the input end of the pump 25, one end of the sewage suction pipe 26 passes through the shell 1 and is arranged above the bucket 12, and a sewage discharge pipe 15 is fixedly arranged at the output end of the pump 25, and one end of the sewage discharge pipe 15 is arranged on the outer wall of the shell 1.

[0039] Specifically, the pump 25 is installed at the inner bottom of the housing 1, and one side is equipped with a battery 27, which is also located at the inner bottom of the housing 1, and the battery 27 provides power support for the entire device. When sewage discharge operation is required, the pump 25 is started, and the pump 25 starts to work, relying on its internal mechanical structure to generate suction. The input end of the pump 25 is fixedly connected to the suction pipe 26, and one end of the suction pipe 26 extends to the top of the bucket 12 after passing through the housing 1. After the bucket 12 scoops up the water plants, silt and other debris at the bottom of the water conservancy project, after preliminary screening by the screen plate 16, smaller silt, sewage and some fine debris will fall into the area below the bucket 12. At this time, the suction generated by the pump 25 is transmitted to the vicinity of its pipe mouth through the suction pipe 26, so that a low-pressure area is formed around the pipe mouth. According to the pressure difference principle, under the action of the external atmospheric pressure, the sludge, sewage and fine debris under the bucket 12 will be sucked into the pump 25 along the sewage suction pipe 26. These sucked substances will be pushed to the output end of the pump 25 according to its internal flow channel as the pump 25 operates. The output end of the pump 25 is fixedly connected to the sewage pipe 15, one end of which is set on the outer wall of the housing 1. The sludge, sewage and other debris pushed by the pump 25 are discharged to the outside of the cleaning device through the sewage pipe 15, and can then be guided to the designated collection location or treatment area to complete the entire sewage discharge process.

[0040] Through the suction force generated by the pump 25 and the complete sewage discharge channel formed by the sewage suction pipe 26 and the sewage discharge pipe 15, pollutants such as silt, sewage and fine debris generated during the cleaning process can be quickly and continuously sucked away and discharged from the cleaning area at the bottom of the water conservancy project, thereby avoiding the accumulation of these pollutants around the cleaning device and affecting the subsequent cleaning work, greatly improving the efficiency of the entire cleaning operation and ensuring that the cleaning work can be carried out uninterruptedly.

[0041] See attached Figure 1 -Attached Figure 8 , a method for using a cleaning device for water conservancy project maintenance, comprising the following steps: S1. Preparation work: survey the area to be cleaned up in the water conservancy project, check the connection and integrity of each component of the device, ensure that the battery power is normal, and set the pressure sensor threshold in the control system according to the debris situation; S2, cleaning operation; start the motor 2 30 to drive the cleaning mechanism to break loose debris; start the motor 17, so that the top rod 19 drives the bucket 12 to control the shovel to scoop up the debris and separate it through the screen under the feedback of the pressure sensor; start the moving mechanism drive device to move and clean according to the route; start the pump 25 to collect and discharge sludge and sewage through the suction pipe 26 and the sewage pipe 15; S3. After the cleaning is completed, all components are shut down and stopped from running, and the device is removed for storage, and the cleaning materials are subsequently processed and the device is cleaned and maintained.

[0042] Specifically, after the motor 2 30 is started, the electrical energy is converted into mechanical energy, which drives the gear 2 22 to rotate through the coupling 31, and the gear 1 21 and the drill rod 3 and spiral blade 4 connected thereto are rotated through the gear transmission. The spiral blade 4 breaks up and loosens the silt, aquatic plants and other debris on the bottom of the water, changes its compact state, and facilitates subsequent cleaning.

[0043] Then, the motor 17 drives the cam 18 to rotate, and drives the push rod 19 to reciprocate up and down with the help of the rotating shaft 20. The pressure sensor at the bottom of the push rod 19 monitors the pressure on the bucket 12 in real time and transmits the signal to the control system. The control system adjusts the stroke of the motor 17 or the push rod 19 according to the preset threshold and the received signal, so that the bucket 12 can shovel the debris adaptively according to the terrain and the debris situation with the cooperation of the spring 14. The shoveled debris is initially separated by the screen plate 16, and the larger debris is intercepted and the small particles of debris fall.

[0044] At the same time, the moving mechanism relies on the transmission shaft 28 to transmit power to drive the driving wheel 7 to rotate. The driving wheel 7 drives the crawler 5 to rotate by means of the engagement with the transmission teeth 11 on the inner wall of the crawler 5. Under the guidance of the guide wheel 8, the load-bearing of the load-bearing wheel 9 and the anti-skid effect of the anti-skid strip 6 on the outer wall of the crawler 5, the device can move stably and flexibly at the bottom of the water conservancy project along a predetermined route to ensure comprehensive cleaning coverage.

[0045] Finally, the pump 25 of the sewage discharge mechanism is started under the power supply of the battery, and its internal impeller rotates to generate suction. The silt, sewage, etc. under the bucket 12 are sucked into the pump 25 through the sewage suction pipe 26 under the action of the pressure difference, and then discharged to the designated location through the sewage discharge pipe 15, thereby collecting and discharging the cleaned pollutants to avoid accumulation affecting the operation.

[0046] The various mechanisms of the entire device complement each other. Through the above-mentioned working principle, it effectively solves the problems faced by traditional cleaning devices, such as difficult cleaning of debris, poor terrain adaptability, and inconvenient sewage discharge, thereby achieving high-quality and efficient maintenance and cleaning work for water conservancy projects.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
