Description

Technical Field

[0001] This utility model relates to the field of river dredging technology, specifically an explosion-proof remote-controlled robot for underwater dredging operations. Background Technology

[0002] In underwater dredging operations, traditional robots face safety risks in flammable and explosive environments and challenges in remote control efficiency. Existing underwater dredging equipment lacks explosion-proof design, easily leading to safety accidents when operating in waters containing flammable gases. Furthermore, the remote control system's anti-interference capability is insufficient, causing operational delays or malfunctions, affecting dredging efficiency. Simultaneously, existing robots have limited ability to break up and collect silt in complex underwater environments, and the breaking process is prone to collisions with rocks, generating sparks, making them unsuitable for challenging dredging scenarios. Therefore, this invention provides an explosion-proof remote-controlled underwater dredging robot to solve the aforementioned problems. Utility Model Content

[0003] The purpose of this invention is to provide an explosion-proof remote-controlled robot for underwater dredging operations to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A remotely controlled underwater dredging robot with explosion-proof features includes a robot body. The robot body includes a support plate. A discharge assembly and a second crushing assembly for cleaning river silt are mounted on the upper surface of the support plate. A first crushing assembly for breaking down the overall structure of the silt is mounted on the front side of the support plate. A flow guide assembly for guiding the air bubbles blown out by the first crushing assembly is engaged at the front end of the first crushing assembly. An air supply assembly for supplying air to the first crushing assembly is mounted on the outer surface of the first crushing assembly. The discharge assembly includes a discharge pipe and a sludge pump. The sludge pump is mounted on the upper surface of the support plate, and the discharge pipe is mounted on the inlet end of the sludge pump.

[0006] As a further embodiment of this utility model, the first crushing component includes a fixing plate, which is installed on the front of the support plate. A fixing sleeve is installed on the front of the fixing plate, a positioning ring is installed on the inner wall of the fixing sleeve, an airbag is installed on the back of the positioning ring, an electric telescopic rod is installed inside the fixing sleeve, a connecting sleeve is installed at the output end of the electric telescopic rod, and the airbag is located on the moving path of the connecting sleeve.

[0007] As a further embodiment of this utility model, the second crushing component includes a base, which is mounted on the upper surface of a support plate. A connecting block is rotatably connected inside the base. A first motor is mounted on the side of the base away from the sludge pump. The output shaft of the first motor passes through the base and is mounted on one side of the connecting block. A hydraulic arm is mounted on the upper surface of the connecting block. A fixed seat is mounted on the top of the hydraulic arm. A top plate is rotatably connected inside the fixed seat. A second motor is mounted on the side of the fixed seat near the sludge pump. The output shaft of the second motor passes through the fixed seat and is mounted on one side of the top plate. A positioning block is mounted on the top of the top plate. A water supply pipe is engaged inside the positioning block.

[0008] As a further embodiment of this utility model, the air replenishment component includes a contact switch, which is installed inside the fixed sleeve and positioned on the moving path of the connecting sleeve. An air supply pipe is installed at the air inlet end of the airbag, and a solenoid valve is installed at the outer end of the air supply pipe. The contact switch and the control end of the solenoid valve are electrically connected.

[0009] As a further embodiment of this utility model, the flow guiding component includes a second magnetic ring, which is snapped onto the front side of the fixed sleeve. A fixed ring is installed on the front side of the second magnetic ring, and a flow guiding cone is installed inside the fixed ring. The flow guiding cone is located on the exhaust path of the airbag.

[0010] As a further embodiment of this utility model, a spring is installed inside the contact switch, and the bottom end of the spring is installed inside the fixed sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. When using this utility model, the connecting sleeve is pushed to slide inside the fixed sleeve by activating the electric telescopic rod. During the sliding process, the connecting sleeve compresses the airbag, causing the gas blown out by the airbag underwater to form bubbles in the water. Since the fixed sleeve is located directly below the drainage end of the second crushing component, the bubbles blown out by the first crushing component break the static sedimentation structure of the silt on the cleaning path of the second crushing component. This allows the second crushing component to quickly disperse the accumulated silt during the opening process, thereby reducing the time spent by the device in cleaning silt and improving the practicality of the device.

[0013] 2. When this utility model is in use, the first motor, hydraulic arm, and second motor drive the top plate to rotate the positioning block on the upper end of the support plate. During the rotation, the positioning block drives the drainage end of the water pipe to adjust its height on the upper end of the support plate, so that the distance between the drainage end of the water pipe and the silt can be adjusted. At this time, the water flow sprayed from the water pipe will flush up the accumulated silt, so that the device does not need to rely on mechanical impact to break the silt when cleaning it. This avoids the sparks generated by the impact during the silt cleaning process, and prevents the device from igniting or exploding flammable and explosive materials during the silt cleaning process. Therefore, the safety of the device during use is improved. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1-6 In this embodiment of the utility model, an explosion-proof underwater dredging remote-controlled robot includes a robot body 1. The robot body 1 includes a support plate 101. A discharge component 2 and a second crushing component 3 for cleaning river silt are installed on the upper surface of the support plate 101. A first crushing component 4 for breaking the overall structure of the silt is installed on the front side of the support plate 101. A guide component 6 for guiding the air bubbles blown out of the first crushing component 4 is snapped at the front end of the first crushing component 4. An air supply component 5 for supplying air to the first crushing component 4 is installed on the outer surface of the first crushing component 4. The discharge component 2 includes a discharge pipe 201 and a sludge pump 202. The sludge pump 202 is installed on the upper surface of the support plate 101, and the discharge pipe 201 is installed at the feed end of the sludge pump 202. Specifically, by activating the first crushing component 4 to discharge air bubbles, the static deposition structure of the silt on the cleaning path of the second crushing component 3 is broken, so that the second crushing component 3 can quickly disperse the accumulated silt, thereby reducing the time spent by the device in the process of cleaning silt and thus improving the practicality of the device.

[0023] The first crushing component 4 includes a fixing plate 406, which is installed on the front of the support plate 101. A fixing sleeve 401 is installed on the front of the fixing plate 406. A positioning ring 404 is installed on the inner wall of the fixing sleeve 401. An air bladder 405 is installed on the back of the positioning ring 404. An electric telescopic rod 402 is installed inside the fixing sleeve 401. A connecting sleeve 403 is installed at the output end of the electric telescopic rod 402. The air bladder 405 is located on the moving path of the connecting sleeve 403. A check valve is installed inside the exhaust end of the air bladder 405. Specifically, when the electric telescopic rod 402 is activated, the connecting sleeve 403 is pushed to slide inside the fixing sleeve 401. When the connecting sleeve 403 slides... Squeezing the airbag 405 causes the gas discharged from the airbag 405 under underwater pressure to form bubbles in the water. Furthermore, the fixed sleeve 401 is located directly below the drain end of the second crushing component 3, so that the bubbles blown out by the first crushing component 4 break the static sedimentation structure of the silt on the cleaning path of the second crushing component 3, thereby enabling the second crushing component 3 to quickly disperse the accumulated silt, thus reducing the time spent by the device in the silt cleaning process and improving the practicality of the device. By installing a check valve inside the exhaust end of the airbag 405, the check valve blocks the exhaust end of the airbag 405, preventing liquid in the water from flowing back into the airbag 405 and causing the airbag 405 to be unable to continuously spray bubbles.

[0024] The second crushing component 3 includes a base 301, which is mounted on the upper surface of the support plate 101. A connecting block 302 is rotatably connected inside the base 301. A first motor 303 is mounted on the side of the base 301 away from the sludge pump 202. The output shaft of the first motor 303 passes through the base 301 and is mounted on one side of the connecting block 302. A hydraulic arm 304 is mounted on the upper surface of the connecting block 302. A fixed seat 305 is mounted on the top of the hydraulic arm 304. A top plate 306 is rotatably connected inside the fixed seat 305. A second motor 307 is mounted on the side of the fixed seat 305 near the sludge pump 202. The output shaft of the second motor 307 passes through the fixed seat 305 and is mounted on one side of the top plate 306. A positioning block 309 is mounted on the top of the top plate 306. A water supply pipe 308 is locked inside the positioning block 309.

[0025] Specifically, by starting the first motor 303, hydraulic arm 304, and second motor 307, the top plate 306 is driven to rotate the positioning block 309 on the upper end of the support plate 101. During the rotation, the positioning block 309 drives the drainage end of the water pipe 308 to adjust its height on the upper end of the support plate 101, so that the distance between the drainage end of the water pipe 308 and the silt can be adjusted. The water flow sprayed from the water pipe 308 washes up the accumulated silt, so that the device does not need to rely on mechanical impact crushing when cleaning silt, thereby avoiding the generation of sparks due to impact during the silt cleaning process, and preventing the device from igniting or detonating flammable and explosive materials during the silt cleaning process, thus improving the safety of the device during use.

[0026] The air replenishment component 5 includes a contact switch 503, which is installed inside the fixed sleeve 401. The contact switch 503 is positioned along the moving path of the connecting sleeve 403. An air supply pipe 502 is installed at the air inlet end of the airbag 405, and a solenoid valve 501 is installed at the outer end of the air supply pipe 502. The contact switch 503 and the control end of the solenoid valve 501 are electrically connected. A mounting hole is provided on the outer surface of the fixed sleeve 401, and the exhaust end of the air supply pipe 502 passes through the mounting hole of the fixed sleeve 401 and is installed inside the air inlet end of the airbag 405. Specifically, the contact switch 503 is positioned along the moving path of the connecting sleeve 403. Between the electric telescopic rod 402 and the airbag 405, when the operator activates the electric telescopic rod 402 to push the connecting sleeve 403 to reciprocate, the contact switch 503 is triggered to open the solenoid valve 501. This causes the electric telescopic rod 402 to pull the connecting sleeve 403 to reset, during which the air supply pipe 502 supplies air into the airbag 405. Conversely, when the connecting sleeve 403 compresses the airbag 405, the connecting sleeve 403 triggers the contact switch 503 to close the solenoid valve 501. At this time, the air supply component 5 automatically replenishes the airbag 405, thereby reducing the time spent by the operator in operating the device and thus improving the practicality of the device.

[0027] The flow guiding assembly 6 includes a second magnetic ring 605, which is snapped onto the front of the fixing sleeve 401. A fixing ring 601 is installed on the front of the second magnetic ring 605, and a flow guiding cone 602 is installed inside the fixing ring 601. The flow guiding cone 602 is located on the exhaust path of the airbag 405. An annular groove is formed on the front of the fixing sleeve 401, and a first magnetic ring 603 is installed inside the annular groove. The second magnetic ring 605 is snapped into the annular groove of the fixing sleeve 401, and the back of the second magnetic ring 605 is adsorbed onto the front of the first magnetic ring 603. A connecting rod 604 is installed on the inner wall of the fixing ring 601, and the flow guiding cone 602 is installed on the front of the connecting rod 604. Specifically, the flow guiding cone 602 is located on the blowing path of the air supply assembly 5. The upper part of the guide cone 602 guides the airflow blown out by the air supply component 5, preventing the airflow from the air supply component 5 from dispersing and failing to form high-speed moving bubbles. This would prevent the air supply component 5 from effectively breaking the static sedimentation structure of the sludge during use, thus improving the stability of the air supply component 5 during use. By pushing the fixing ring 601, the second magnetic ring 605 is engaged inside the fixing sleeve 401. At this time, the back of the second magnetic ring 605 is adsorbed onto the front of the first magnetic ring 603, so that the second magnetic ring 605 and the first magnetic ring 603 restrict the movement of the fixing ring 601 at the front end of the fixing sleeve 401, thereby preventing the guide cone 602 from being subjected to long-term bubble impact, which would cause the fixing ring 601 to fall off from the front end of the fixing sleeve 401.

[0028] A spring 7 is installed inside the contact switch 503. The bottom end of the spring 7 is installed inside the fixed sleeve 401. A groove is formed on the lower surface of the contact switch 503. The spring 7 is installed on the top of the inner wall of the groove of the contact switch 503, and the bottom end of the spring 7 is installed on the bottom of the inner wall of the slot of the fixed sleeve 401. Specifically, the spring 7 uses its own extension to push the fixed sleeve 401 to slide upward inside the groove of the contact switch 503, so that the top of the contact switch 503 is always located on the moving path of the connecting sleeve 403. This prevents the contact switch 503 from shortening in length after being rubbed by the connecting sleeve 403 for a long time, which would prevent the connecting sleeve 403 from triggering the contact switch 503 to start the solenoid valve 501 during the movement. Therefore, the number of times the contact switch 503 needs to be replaced by the staff is reduced.

[0029] The working principle of this utility model is as follows:

[0030] When using this invention, the electric telescopic rod 402 is activated, pushing the connecting sleeve 403 to slide within the fixed sleeve 401. As the connecting sleeve 403 slides, it compresses the airbag 405, causing the gas expelled from the airbag 405 underwater to form bubbles. Furthermore, the fixed sleeve 401 is located directly below the drain end of the second crushing component 3, allowing the bubbles blown out by the first crushing component 4 to break the static sedimentation structure of the silt on the cleaning path of the second crushing component 3. This enables the second crushing component 3 to quickly disperse the accumulated silt, thereby reducing the time spent cleaning the silt. The guide cone 602 is positioned on the air blowing path of the air supply component 5, guiding the airflow from the air supply component 5. This prevents the airflow from the air supply component 5 from dispersing and failing to form high-speed moving bubbles, thus ensuring the air supply component 5 can effectively break the static sedimentation structure of the silt during use.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
