[0001] This utility model relates to the technical field of pipeline dredging equipment, and more specifically, to a cleaning mechanism and dredging equipment. Background Technology
[0002] Pipelines are an important drainage structure in water conservancy projects. Pipelines used for drainage and sewage discharge are often clogged by sediment, garbage, and other debris. To ensure the normal operation of the drainage system, dredging devices are needed to clean the inside of the pipes. To allow operators to monitor the inside of the pipes in real time, the chassis of the dredging device is usually equipped with a camera that also has lighting capabilities.
[0003] In related technologies, dredging devices generally use a rotating brush head to loosen the silt deposited in the pipe, and finally the dredging operation in the pipe can be completed under the action of water flow.
[0004] However, due to the complex environment inside the pipeline, silt and sewage can easily cover the camera during dredging operations, resulting in blurry images and poor lighting, which affects the smooth progress of the dredging operation and the evaluation of the dredging effect.

[0023] During the dredging operation, the lifting structure drives the cleaning brush structure to move up and down to remove debris (silt and stains) from the camera surface. A water supply system provides a stream of clean water to the first nozzle to initially remove some stains from the camera surface. Since the first nozzle is positioned diagonally above the camera, it does not obstruct the camera's view of the pipe. Spraying water onto the camera surface in conjunction with the up-and-down movement of the cleaning brush structure effectively improves the cleaning effect, ensuring clear images and good lighting. This allows operators to accurately assess the situation inside the pipe, improves the dredging efficiency, and facilitates evaluation of the dredging results by personnel outside the pipe.

[0037] To address the problems existing in the aforementioned related technologies, this embodiment provides a sludge removal device for a cleaning mechanism.
[0038] like Figure 1 and Figure 2 As shown in the figure, this utility model provides a cleaning mechanism suitable for dredging equipment. The dredging equipment includes a chassis 300 and a camera 400 mounted on the chassis 300. The cleaning mechanism includes:
[0039] A water supply structure 100 is fixedly installed on the chassis 300, and the water supply structure 100 is used to provide clean water flow;
[0040] A cleaning device 200 includes a first water spray assembly 210 and a cleaning assembly 220. The first water spray assembly 210 includes a first nozzle 211, and the water supply structure 100 is connected to the first nozzle 211. The first nozzle 211 is positioned diagonally above the camera 400 and is used to spray a first stream of water onto the camera 400. The cleaning assembly 220 includes a cleaning brush structure 221 and a lifting structure 222. The cleaning brush structure 221 is positioned on one side of the shooting area of the camera 400, and the lifting structure 222 is fixedly installed on the chassis 300. The lifting structure 222 is fixedly connected to the cleaning brush structure 221 and is used to drive the cleaning brush structure 221 to move up and down.
[0041] Specifically, the camera 400 is fixedly mounted on the chassis 300.
[0042] The water supply structure 100 can be a water tank structure, which is used to hold clean water. The water supply structure 100 is connected to the first nozzle 211 through a pipeline to deliver clean water to the first nozzle 211. The first nozzle 211 can be fixedly installed above the camera 400 by means of connectors such as clips or brackets.
[0043] The first nozzle 211 is positioned diagonally above the camera 400. This means that the first nozzle 211 is located above and in front of the camera 400, not directly above it, to ensure that the first stream of water sprayed from the first nozzle 211 can completely spray the shooting area of the camera 400, so as to initially remove debris from the surface of the shooting area of the camera 400.
[0044] The lifting structure 222 can be arranged vertically and fixedly installed on the chassis 300. The lifting structure 222 can be a vertically arranged linear motion device, such as an electric push rod, a combination of a rotary motor and a ball screw element, etc. Any linear motion device that can drive the lifting motion of the cleaning brush structure 221 is applicable to this technical solution, and no specific limitation is made here.
[0045] The piston rod of the lifting structure 222 is fixedly connected to the cleaning brush structure 221, and is used to drive the cleaning brush structure 221 to move up and down. The cleaning brush structure 221 can be installed on one side of the shooting area of the camera 400, in other words, it can be installed below the front of the camera 400. When cleaning of the camera 400 is not required, the piston rod of the lifting structure 222 is in the retracted state, and the cleaning brush structure 221 is below the camera 400, which does not obstruct the shooting range of the camera 400; when cleaning of the camera 400 is required, the piston rod of the lifting structure 222 intermittently enters the extended or retracted state, and drives the cleaning brush structure 221 to perform corresponding lifting and lowering movements.
[0046] Regarding the frequency and duration of the lifting structure 222 driving the cleaning brush structure 221 to lift and lower, cleaning the camera 400, the following methods can be used: manual remote control via a remote control to control the lifting structure 222; or a time relay can be installed on the chassis 300 to pre-set the intervals for the lifting structure 222 to lift and lower for a preset time. Alternatively, after the dredging equipment enters the pipeline, a control device on the chassis 300 can be used to control the lifting structure 222 to continuously extend and retract, controlling the cleaning brush structure 221 to continuously clean the camera 400. Therefore, any existing control strategy that can control the lifting structure 222 to drive the cleaning brush structure 221 to lift and lower to clean the camera 400 is applicable to this technical solution and is not specifically limited here.
[0047] In this embodiment, the dredging equipment mainly includes a chassis 300, a cleaning mechanism, a camera 400, and a dredging body mounted on the chassis 300. The chassis 300 can move inside the pipeline. The dredging body can clean the sediment and accumulated debris inside the pipeline. The camera 400, which also has a lighting function, can capture the scene inside the pipeline so that the operator can know the internal condition of the pipeline. During the dredging operation, for debris covering the surface of the camera 400, the lifting structure 222 drives the cleaning brush structure 221 to move up and down, so as to wipe away the debris (silt and stains) on the surface of the camera 400 through the up-and-down movement of the cleaning brush structure 221. Clean water can be provided by the water supply structure 100 and delivered to the first nozzle 211 to initially remove some stains on the surface of the camera 400. Since the first nozzle 211 is located diagonally above the camera 400, it not only avoids obstructing the camera 400's shooting range inside the pipeline, but also... The first water stream sprayed by the first nozzle 211 above the camera 400 flows from top to bottom along the surface of the camera 400 to wash away debris. By spraying water onto the surface of the camera 400 through the first nozzle 211 and coordinating with the up-and-down movement of the cleaning brush structure 221, the cleaning effect on the camera 400 can be improved more effectively, ensuring that the image captured by the camera 400 is clear and the lighting effect is good. This helps operators to accurately grasp the situation inside the pipeline, improves the effect of dredging operations, and facilitates the evaluation of the dredging effect by workers outside the pipeline.
[0048] Optionally, combined Figure 3 As shown, the cleaning brush structure 221 includes a mounting base 2211 and a cleaning brush body 2212. The mounting base 2211 is provided with a slot 22110, and a portion of the cleaning brush body 2212 is embedded in the slot 22110.
[0049] Specifically, the bristles of the cleaning brush body 2212 can be made of a soft and wear-resistant material to avoid scratching the surface of the camera 400. The soft bristles will not scratch the surface of the camera 400, protecting the camera 400 from damage. At the same time, the wear-resistant properties can ensure that the bristles will not wear out too quickly during multiple cleaning processes, maintaining a good cleaning effect and enabling it to effectively clean the camera 400 for a long time.
[0050] Mounting base 2211 is provided with a slot 22110, the slot 22110 along... Figure 3 The height of the slot 22110 in the Z-axis direction of the coordinate system is less than or equal to the height of the cleaning brush body 2212, so that the cleaning brush body 2212 can be smoothly embedded in the slot 22110 of the mounting base 2211.
[0051] The card slot 22110 along Figure 3 The depth of the dimensional slot 22110 along the Y-axis in the coordinate system, and the cleaning brush body 2212 along... Figure 3 The width of the cleaning brush body 2212 is measured along the Y-axis in the coordinate system. Part of the cleaning brush body 2212 is embedded in the slot 22110. It can be understood that the width of the cleaning brush body 2212 can be greater than the height of the slot 22110 so that the bristles of the cleaning brush body 2212 can protrude out of the slot 22110.
[0052] Mounting base 2211 can adopt a "C"-shaped structure.
[0053] The bristles of the cleaning brush body 2212 face the camera 400.
[0054] In this optional embodiment, the cleaning brush body 2212 is embedded in the slot 22110 of the mounting base 2211, so that the cleaning brush body 2212 is vertically limited by the slot 22110 to prevent the cleaning brush body 2212 from dislodging from the slot 22110 of the mounting base 2211 during the lifting and lowering movement to clean the camera 400. Since a portion of the cleaning brush body 2212 is embedded in the slot 22110, the bristles of the cleaning brush body 2212 protrude from the slot 22110. This not only facilitates the brush bristles' contact with the camera 400 at various stages, but also prevents other parts of the cleaning brush body 2212 from rubbing against the camera 400 and scratching the shooting area of the camera 400.
[0055] Optionally, combined Figure 3 As shown, the cleaning brush structure 221 further includes a fastening structure 2213. The mounting base 2211 is provided with a first connecting hole, and the cleaning brush body 2212 is provided with a second connecting hole 22120. The fastening structure 2213 passes through the first connecting hole and is inserted into the second connecting hole 22120 to fix the cleaning brush body 2212 and the mounting base 2211.
[0056] Specifically, when the cleaning brush body 2212 is embedded in the slot 22110 of the mounting base 2211, the second connecting hole 22120 on the cleaning brush body 2212 corresponds to the position of the first connecting hole of the mounting base 2211.
[0057] The fastening structure 2213 can be a bolt fastener or a rod-shaped connector with external threads. The first connecting hole can be a threaded hole or a through hole with a smooth inner wall. The second connecting hole 22120 can be a threaded hole. After the fastening structure 2213 is screwed into the second connecting hole 22120 in a spiral manner, the cleaning brush body 2212 can be fixed in the slot 22110 of the mounting base 2211.
[0058] In this optional embodiment, after the cleaning brush body 2212 is embedded in the slot 22110 of the mounting base 2211, the fastening structure 2213 can pass through the first connecting hole of the mounting base 2211 and the second connecting hole 22120 of the cleaning brush body 2212 to fix the cleaning brush body 2212 to the mounting base 2211. This connection method also facilitates the disassembly and replacement of the cleaning brush body 2212, preventing it from becoming unusable when the bristles of the cleaning brush body 2212 are severely worn, thus ensuring the continuous and effective operation of the cleaning work.
[0059] Optionally, combined Figure 3 As shown, the mounting base 2211 includes a mounting base body 22111 and a connecting cylinder 22112. The slot 22110 of the mounting base body 22111 is used to install the cleaning brush body 2212. The connecting cylinder 22112 is fixedly connected to the side wall of the mounting base body 22111 away from the cleaning brush body 2212. The connecting cylinder 22112 is provided with the first connecting hole. The fastening structure 2213 includes a screw 22131 and a knob 22132. One end of the screw 22131 is fixedly connected to the knob 22132. The other end of the screw 22131 passes through the first connecting hole of the connecting cylinder 22112 and is inserted into the second connecting hole 22120.
[0060] Specifically, if the first connecting hole of the connecting cylinder 22112 is an internally threaded hole, the connecting cylinder 22112 can be an internally threaded pipe; if the first connecting hole of the connecting cylinder 22112 is a through hole with a smooth inner wall, the connecting cylinder 22112 can be a cylindrical structure with a smooth inner wall.
[0061] The axis of the connecting cylinder 22112 is parallel to the axis of the screw 22131 of the fastening structure 2213, and is also parallel to the axis of the fastening structure 2213. Figure 3 The Y-axis is parallel in the coordinate system.
[0062] The connecting cylinder 22112 penetrates the mounting base body 22111, so that the first connecting hole is a through hole structure.
[0063] The mounting base body 22111 can be a C-shaped structure, and the mounting base body 22111 can have a slot 22110, into which the cleaning brush body 2212 can be embedded.
[0064] The connecting cylinder 22112 and the mounting base body 22111 can be constructed as an integral structure to ensure the mechanical strength of the mounting base 2211. If the mounting base 2211 includes one connecting cylinder 22112, the connecting cylinder 22112 can be fixed to the middle of the mounting base body 22111; if the mounting base 2211 includes multiple connecting cylinders 22112, the multiple connecting cylinders 22112 can be fixed at equal intervals along the length direction of the mounting base 2211 to the side wall of the mounting base body 22111 away from the cleaning brush body 2212.
[0065] In this optional embodiment, after the cleaning brush body 2212 is embedded in the slot 22110 of the mounting base body 22111, the manually operable knob 22132 can be rotated to allow the screw 22131 to pass through the first connecting hole of the connecting cylinder 22112 and be inserted into the second connecting hole 22120 of the cleaning brush body 2212 by rotation, thereby fixing the cleaning brush body 2212 in the slot 22110 of the mounting base body 22111. Since the connecting cylinder 22112 is fixed to the side wall of the mounting base body 22111 away from the cleaning brush body 2212, the connecting cylinder 22112 will not interfere with the installation of the cleaning brush body 2212 in the slot 22110; furthermore, the connecting cylinder 22112 effectively increases the overall length of the mounting base 2211. Figure 3 The dimension in the Y-axis direction of the coordinate system, when the screw 22131 passes through the first connecting hole of the connecting cylinder 22112, is used to further improve the connection stability between the fastening structure 2213 and the mounting base 2211 by increasing the connection length between the screw 22131 and the mounting base 2211.
[0066] Optionally, combined Figure 4 and Figure 5 As shown, the cleaning device 200 further includes a guide assembly 230, which includes a guide rod 231 and a guide block 232. The guide rod 231 and the lifting structure 222 are spaced apart along a first direction and fixed to the chassis 300. The guide block 232 is fixed to the side wall of the mounting base 2211 away from the cleaning brush body 2212. The guide block 232 is provided with a third connecting hole 2320, and the guide rod 231 passes through the third connecting hole 2320. The first direction refers to the width direction of the chassis 300.
[0067] Specifically, the cleaning device 200 may include at least one guide assembly 230, wherein the guide rods 231 of the guide assembly 230 may be spaced apart from the lifting structure 222 along a first direction, the first direction referring to the width direction of the chassis 300, and may be... Figure 4 The X-axis is parallel in the coordinate system.
[0068] The cleaning device 200 may include two guide assemblies 230 (see...) Figure 4(As shown); the two guide components 230 can be located on opposite sides of the lifting structure 222.
[0069] The bottom end of the guide rod 231 can be vertically fixedly installed on the chassis 300. The guide block 232 can be fixedly installed on the side wall of the mounting body 22111 away from the cleaning brush body 2212, and the guide block 232 and the connecting cylinder 22112 can be arranged at intervals along the first direction.
[0070] The guide block 232 is provided with a third connecting hole 2320, and the guide rod 231 can vertically pass through the third connecting hole 2320 of the guide block 232.
[0071] In this optional embodiment, a guide rod 231 of the guide assembly 230 is fixedly connected to the top of the chassis 300. A guide block 232 is fixedly connected to the side wall of the mounting body 22111 away from the cleaning brush body 2212, corresponding to the position of the guide rod 231. The guide rod 231 is inserted into the third connecting hole 2320 of the guide block 232. Here, the guide assembly 230 can accurately guide the lifting movement of the mounting body 2211, so that it can move stably along a predetermined trajectory under the push of the lifting structure 222. This ensures that the cleaning brush body 2212 can accurately clean the camera 400, improves the accuracy and reliability of cleaning, and avoids the cleaning brush body 2212 failing to effectively clean the camera 400 due to movement deviation, or causing damage to the camera 400.
[0072] Optionally, combined Figure 2 As shown, the first water spray assembly 210 also includes a water pump 212 and a first water supply pipe 213. The water inlet of the water pump 212 is connected to the water supply structure 100, and the water outlet of the water pump 212 is connected to the first nozzle 211 through the first water supply pipe 213.
[0073] Specifically, the water pump 212 is used to draw clean water from the water supply structure 100 and deliver it to the first nozzle 211 via the first water pipe 213.
[0074] The water pump 212 can be fixedly installed on the chassis 300. The inlet of the first water supply pipe 213 is connected to the outlet of the water pump 212, and the outlet of the first water supply pipe 213 is connected to the first nozzle 211. Part of the first water supply pipe 213 is located above the camera 400, and the camera 400 can provide a certain support for the first water supply pipe 213 and the first nozzle 211.
[0075] The first water supply pipe 213 can adopt a metal flexible hose structure, which can extend the service life of the first water supply pipe 213.
[0076] In this optional embodiment, the camera 400 can be sprayed and cleaned in the following way: for example, the water pump 212 can be activated to extract the clean water flow in the water supply structure 100 and deliver it to the first nozzle 211 through the first water supply pipe 213 so as to spray water on the surface of the camera 400 through the first nozzle 211.
[0077] Combination Figure 1 As shown in the figure, the present invention provides a dredging device including a chassis 300, two cameras 400 and a cleaning mechanism as described in the above embodiment. The two cameras 400 are installed on the chassis 300 at intervals along a second direction. The two cleaning devices 200 of the cleaning mechanism are respectively used to clean the cameras 400 at corresponding positions. The second direction refers to the forward and backward direction of the chassis 300.
[0078] Specifically, the second direction can be related to Figure 1 The Y-axis in the coordinate system is parallel and can refer to the forward and backward direction (or front and back direction) of the chassis 300.
[0079] Two cameras 400 can be installed at intervals on the top of the chassis 300 along the forward and backward direction of the chassis.
[0080] Each camera 400 may be configured with a cleaning device 200, so that cleaning operations can be performed on the camera 400 at the corresponding location by each cleaning device 200.
[0081] The water supply structure 100 can be located between two cameras 400.
[0082] The two cleaning devices 200 and the two cameras 400 can be arranged as follows: in the front cleaning device 200, the cleaning component 220 of the cleaning device 200 is located in front of the front camera 400; in the rear cleaning device 200, the cleaning component 220 of the other cleaning device 200 is located behind the rear camera 400.
[0083] The water pump 212 of the first water spray assembly 210 in the two cleaning devices 200 can be connected to the water supply structure 100 respectively. In other words, the first water spray assembly 210 of the two cleaning devices 200 can share a water supply structure 100, thereby reducing the number of water supply structures 100.
[0084] The front-end camera 400 can be used to capture the scene inside the pipe at the front of the chassis 300, and the rear-end camera 400 can be used to capture the scene inside the pipe at the rear of the chassis 300.
[0085] The chassis 300 may include a chassis body and a tracked walking mechanism mounted on the chassis body. For example, a tracked walking mechanism may be mounted on the left and right ends of the chassis body, and the walking action of the entire dredging equipment can be realized through the tracked walking mechanisms on the left and right ends of the chassis body.
[0086] The tracks in the tracked walking mechanism of the chassis 300 can be made of wear-resistant rubber material. Its flexibility can adapt to the uneven and slippery complex terrain of the pipeline bottom, ensuring that the dredging equipment can move stably in the pipeline and is not prone to slipping or sinking.
[0087] The dredging equipment in this embodiment has the same beneficial effects as the existing technology compared to the cleaning mechanism described above, and will not be repeated here.
[0088] Optionally, combined Figure 6 As shown, the dredging equipment also includes a dredging body, which includes a dredging component 500. The dredging component 500 includes a support structure 510, a drive motor 520, and a brush head 530. The support structure 510 is fixedly installed on the front end of the chassis 300. The drive motor 520 is fixedly connected to the support structure 510. The motor shaft of the drive motor 520 is fixedly connected to the brush head 530 for driving the brush head 530 to rotate. The brush head 530 is arranged facing downwards.
[0089] Specifically, the entire dredging assembly 500 can be located at the front end of the chassis 300; the support structure 510 can adopt the following structure, for example, the support structure 510 includes a support rod 511 and a support plate 512. One end of the support rod 511, for example, the rear end, is fixedly connected to the front end of the chassis 300, and the other end of the support rod 511, for example, the front end, is fixedly connected to the support plate 512. The fixed end of the drive motor 520 can be fixedly installed on the support plate 512. The motor shaft of the drive motor 520 passes downward through the support plate 512 and is fixedly connected to the brush head 530 for driving the brush head 530 to rotate. Therefore, the brush head 530 can be located below the drive motor 520. Thus, the support plate 512 provides a certain mounting base for the drive motor 520.
[0090] The brush head 530 can be made of a flexible and wear-resistant steel wire brush. This flexible and wear-resistant steel wire brush can ensure the thoroughness of cleaning the inside of the pipe, while ensuring that the brush head 530 will not wear out or deform quickly when it encounters hard objects such as stones, thus ensuring the durability of cleaning.
[0091] The drive motor 520 can be a rotary motor.
[0092] In this optional embodiment, when the chassis 300 is moving inside the pipe, the drive motor 520 can be started, so that the output end of the drive motor 520 drives the brush head 530 to rotate, thereby using rotation to break up the sediment and silt accumulated on the bottom wall of the pipe, so as to achieve the sludge removal operation inside the pipe.
[0093] The dredging equipment also includes a power supply unit, which can be fixedly installed on the chassis 300 and can be electrically connected to the water pump 212 of the first water spraying component 210, the lifting structure 222 of the cleaning component 220, the drive motor 520 of the dredging component 500 and the camera 400. It can be used to provide working power to the water pump 212, the lifting structure 222, the drive motor 520 and the camera 400.
[0094] Optionally, combined Figure 6 As shown, the dredging body includes two dredging components 500, which are arranged at a distance from each other along a first direction at the front end of the chassis 300.
[0095] The two brush heads 530 rotate in opposite directions.
[0096] Specifically, the first direction can be related to Figure 6 In the coordinate system, the X-axis is parallel and can refer to the width direction of the chassis 300 or the left-right direction.
[0097] The two dredging components 500 can be arranged at a distance from each other along the first direction at the front end of the chassis 300; the two brush heads 530 rotate in opposite directions, which can be understood as follows: for example, the brush head 530 on the left rotates counterclockwise and the brush head 530 on the right rotates clockwise.
[0098] In this optional embodiment, the dredging body includes two dredging components 500 arranged at intervals along a first direction. This not only increases the dredging range for debris in the pipe, but also ensures that the two brush heads 530 corresponding to the two dredging components 500 rotate in opposite directions. For example, the brush head 530 on the left front end of the chassis 300 rotates counterclockwise, and the brush head 530 on the right front end of the chassis 300 rotates clockwise. The opposite rotation of the two brush heads 530 can counteract the additional force caused to the chassis 300 by the rotation of the brush heads 530, thereby ensuring that the chassis can move smoothly in the pipe.
[0099] Optionally, combined Figure 6 As shown, the dredging body also includes a second water spraying assembly 600. The second water spraying assembly 600 includes a second water supply pipe 610 and a second nozzle 620. The second water supply pipe 610 is fixedly installed on the chassis 300. One end of the second water supply pipe 610 is used to connect to the water supply mechanism, and the other end of the second water supply pipe 610 is connected to the second nozzle 620.
[0100] The second nozzle 620 is used to fix the front end of the chassis 300.
[0101] Specifically, the water supply mechanism can be a water supply tank located outside the pipeline. For example, the water supply tank can be connected to one end of the second water supply pipe 610 through the pump body, and the other end of the second water supply pipe 610 can be connected to the second nozzle 620.
[0102] The second water spray component 600 can be mounted on the chassis 300 and located on the side of the camera 400 along the width direction of the chassis 300, so as to make full use of the side space of the camera 400 on the top of the chassis 300.
[0103] The dredging unit may include at least two second water spray components 600, which may be located on the left and right sides of the camera, thereby increasing the flushing range of debris in the pipe.
[0104] The second water supply pipe 610 and the second nozzle 620 are both fixedly installed on the chassis 300, and the spray nozzle of the second nozzle 620 can face the brush head 530.
[0105] The second nozzle 620 may have a flat and wide structure, and the second nozzle 620 sprays a second stream of water downwards and forwards to wash away debris.
[0106] In this optional embodiment, since the second nozzle 620 can adopt a flat and wide structure, and the second nozzle 620 sprays a second water flow towards the lower front to flush away the silt, garbage and other debris in front of the chassis 300, and works well with the brush head 530 of the sludge removal component 500 to remove silt, the spray coverage area can be increased, making the flushing range of silt, debris and other debris in front of the pipe wider and more uniform, and can more effectively flush away obstacles in front, creating good conditions for the movement of the sludge removal equipment and subsequent sludge removal operations, and reducing the obstacles encountered by the sludge removal equipment when it moves.
[0107] The dredging equipment can operate as follows: For example, during operation, after entering a pipeline such as a municipal water pipeline, the chassis 300 takes effect, relying on its wear-resistant rubber tracks to move stably within the pipeline, propelling the entire dredging equipment forward. The water supply mechanism supplies water to the second nozzle 620 located on one side of the forward end of the chassis 300 via the second water pipe 610. The second nozzle 620 sprays water over a large area at a suitable angle to flush away silt, garbage, and other debris in front of the pipeline, dispersing them. Simultaneously, two drive motors 520 are activated, causing the output ends (i.e., motor shafts) of the two drive motors 520 corresponding to the two dredging components 500 to drive the two brush heads 530 to rotate in opposite directions. This, combined with the second water flow from the second nozzle 620, achieves a better dredging effect by flushing away debris in the pipeline, allowing the dredging equipment to move forward smoothly.
[0108] During the dredging operation, the camera 400 can capture and provide real-time feedback on the internal conditions of the pipe. When the camera 400 becomes blurry or the lighting effect deteriorates due to silt, sewage, or other contaminants, the cleaning mechanism begins operation. First, the water pump 212 draws water from the water supply structure 100, such as a water tank. After passing through the water pump 212, the water is transmitted to the first nozzle 211 via the first water pipe 213. The first nozzle 211 sprays water diagonally upwards towards the camera 400, rinsing the surface of the camera 400 and initially removing some dirt. Simultaneously, the lifting mechanism... The mechanism 222 pushes the mounting base 2211 to move up and down. The guide block 232 fixed on the mounting base 2211 moves up and down along the guide rod 231, which drives the cleaning brush body 2212 to wipe the camera 400. The cleaning brush body 2212 has soft and wear-resistant bristles that thoroughly remove the remaining dirt when it comes into contact with the surface of the camera 400, so that the camera 400 can restore a clear shooting image and good lighting effect, so that the operator can continue to accurately grasp the situation inside the pipeline and ensure that the dredging operation can be carried out smoothly and efficiently.
[0109] If the bristles of the cleaning brush body 2212 wear out after prolonged use of the cleaning brush structure 221 and need to be replaced, the knob 22132 can be turned to unscrew the screw 22131 from the second connecting hole 22120 of the cleaning brush body 2212 and the first connecting hole of the mounting base 2211, so that the cleaning brush body 2212 can be pulled out from the slot 22110 of the mounting base 2211 and a new cleaning brush body 2212 can be replaced; then the new cleaning brush body 2212 can be inserted. Insert the brush into the slot 22110 of the mounting base 2211, rotate the knob 22132, the knob 22132 drives the screw 22131 through the connecting cylinder 22112 of the mounting base 2211 and insert it into the second connection of the cleaning brush body 2212, and finally rotate the knob 22132 slightly to fix the cleaning brush body 2212 in the slot 22110 of the mounting base 2211, thereby enabling convenient adjustment of the cleaning brush body 2212.
[0110] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
