Description

Technical Field

[0001] This utility model relates to the field of underwater dredging technology, and in particular to an underwater dredging robot. Background Technology

[0002] Currently, the main method for cleaning silt from inside pools (or other containment structures) is manual dredging. However, manual dredging is labor-intensive, inefficient, and poses certain safety hazards. Using underwater dredging equipment to replace manual dredging can significantly reduce labor intensity and prevent safety accidents during the dredging process.

[0003] There are various underwater dredging devices in the prior art, such as an underwater dredging machine with publication number CN219952206U, which includes a body and a walking track. The lower end of the body is provided with a connecting device, and a support device is connected to the connecting device. The support device is used to move and support the body. The support device includes a telescopic rod at the bottom of the body, the bottom end of which is connected to the top of a support. The bottom end of the support is equipped with a roller, and the side wall of the support is provided with a protrusion. The protrusion on the side wall of the support moves and contacts a sliding block to support the sliding block to move downward. The sliding block is slidably engaged with the connecting device to move and engage with the lower end of the protrusion on the side wall of the support. The end of the sliding block away from the support is provided with a push rod for pushing the sliding block to move laterally. This enables the dredging machine to automatically cross obstacles. However, the above device can only move at the bottom of the pool and cannot clean silt and other impurities on the side wall of the pool, which is still inconvenient to use.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0021] See Figures 1-3 This utility model provides an underwater dredging robot, including a housing 1 and a traveling component 2. The housing 1 has a water storage chamber 11 and a sludge storage chamber 12 inside. The sludge storage chamber 12 is located below the water storage chamber 11. A sludge suction device 15 is provided at one end of the housing 1. The sludge suction device 15 is connected to the sludge storage chamber 12 and can suck underwater sludge and other debris into the sludge storage chamber 12 for temporary storage. The sludge suction device 15 is a relatively mature existing technology, so it will not be described in detail in this utility model.

[0022] See Figures 1-3The traveling component 2 includes a floating shaft 21 and a movable seat 211. The floating shaft 21 is rotatably mounted at one end of the water storage chamber 11 near the suction device 15. Both ends of the floating shaft 21 are rotatably connected to the side wall of the water storage chamber 11. Two movable seats 211 are provided on the floating shaft 21. The surface of the floating shaft 21 is provided with two circulation grooves in opposite directions (the circulation grooves are arc-shaped grooves that circle the floating shaft 21 and are connected end to end). The movable seats 211 are correspondingly matched with the floating shaft 21 (that is, the movable seats 211 are provided with through holes for the floating shaft 21 to cooperate with, and the inner side wall of the through holes is provided with guide posts that cooperate with the circulation grooves). The water storage chamber 11 contains... A piston 212 is slidably provided, and a cross rod assembly 213 is provided between the piston 212 and the movable seat 211 (that is, the two ends of one side of the cross rod assembly 213 are rotatably connected to the two movable seats 211 respectively, and the two ends of the other side of the cross rod assembly 213 are rotatably connected to the sliders, and the sliders are slidably connected to the piston 212). The end of the water storage chamber 11 away from the vacuum cleaner 15 has an opening. When the piston 212 moves towards the vacuum cleaner 15, water flows into the water storage chamber 11, and the box 1 can sink at this time. When the piston 212 moves away from the vacuum cleaner 15, it can form a cavity in the water storage chamber 11, causing the box 1 to float.

[0023] See Figures 1-3 On the outer side walls of the housing 1 away from the vacuum cleaner 15, several side fan blades 25 are rotatably mounted. When the side fan blades 25 rotate individually, they can drive the housing 1 to turn. A left-turning shaft 23 and a right-turning shaft 24 are rotatably mounted next to the floating shaft 21. One end of the left-turning shaft 23 passes through the housing 1 and is connected to the several side fan blades 25 on one side wall of the housing 1 by a first belt. One end of the right-turning shaft 24 passes through the housing 1 and is connected to the several side fan blades 25 on the other side wall of the housing 1 by a first belt. Thus, when the left-turning shaft 23 or the right-turning shaft 24 rotates individually, it can drive the housing 1 to turn. A drive shaft 26 is rotatably mounted on the end of the water storage chamber 11 near the vacuum cleaner 15. One end of the drive shaft 26 is connected to a drive component (not shown in the figure). The drive component is located on one side wall of the water storage chamber and can drive the drive shaft 26 to rotate back and forth. A mounting base 261 is rotatably mounted on the drive shaft 26. A ratchet is mounted on the mounting base 261. The ratchet is concentric with the drive shaft 26. A unidirectional rotatable pawl is rotatably mounted on the drive shaft 26. A drive gear 262 is rotatably mounted on the mounting base 261. The drive gear 262 is rotatably connected to the mounting base 261 via a positioning shaft. A second belt is provided between the drive shaft 26 and the positioning shaft. A floating shaft 21 is provided with a floating gear 22 that can mesh with the drive gear 262. A left-turning shaft 23 is provided with a left-turning gear 231 that can mesh with the drive gear 262. A right-turning shaft 24 is provided with a right-turning gear 241 that can mesh with the drive gear 262.

[0024] See Figures 1-3The housing 1 is equipped with several connecting shafts 29 that rotate within it. The connecting shafts 29 are all located between the water storage chamber 11 and the sludge storage chamber 12. The end of the connecting shaft 29 that is away from the sludge suction device 15 passes through the housing 1 and connects to the rear fan blade 293. A third belt is provided between the several connecting shafts 29. A forward shaft 27 is rotatably provided at one end of the water storage chamber 11 near the vacuum cleaner 15. A forward gear 271 that can mesh with the drive gear 262 is provided on the forward shaft 271. Half gears 272 are provided on the forward shaft 27 on both sides of the forward gear 271. A lifting plate 28 is slidably provided on the side wall of the water storage chamber 11 near the vacuum cleaner 15. A fixed plate 282 is provided on the side wall of the water storage chamber 11 above the lifting plate 28. Several springs are provided between the fixed plate 282 and the lifting plate 28. A rack 281 that can mesh with the half gear 272 is provided on the lifting plate 28. A turntable 291 is provided on one of the connecting shafts 29. An eccentric rod 292 is rotatably provided between the lifting plate 28 and the turntable 291 (i.e., one end of the eccentric rod 292 is rotatably connected to the lifting plate 28, and the other end of the eccentric rod 292 is rotatably connected to the turntable 291, and the connection point between the eccentric rod 292 and the turntable 291 is not concentric with the turntable 291).

[0025] See Figures 1-3 Preferably, the left rotating shaft 23 and the housing 1, and the right rotating shaft 24 and the housing 1 are all connected by a rotating seal, which can prevent water from accidentally entering the water storage chamber 11.

[0026] See Figures 1-3 Preferably, a grille 13 is provided at one end of the opening of the water storage chamber 11, which can reduce the risk of dirt in the water entering the water storage chamber 11.

[0027] See Figures 1-3 Preferably, both the drive unit and the vacuum cleaner 15 are waterproofed.

[0028] See Figures 1-3 Preferably, the bottom surface of the box 1 is provided with several casters 14 to facilitate the movement of the box 1.

[0029] See Figures 1-3 Preferably, the belt drive in this utility model can be replaced with chain drive to ensure good transmission effect. The addition of transmission gears and the matching of chain and transmission gear are conventional technical operations for those skilled in the art, so they will not be described in detail.

[0030] See Figures 1-3 Preferably, the bottom surface of the sludge storage chamber 12 is detachably connected to a base plate, which facilitates the user to clean the sludge storage chamber 12.

[0031] In the implementation of this utility model: the user places the housing 1 in the pool and starts the drive unit. The drive unit rotates forward, at which time the ratchet and pawl engage, and the drive shaft 26 drives the mounting base 261 to rotate, causing the drive gear 262 to mesh with the floating gear 22. Then the drive unit reverses, causing the floating shaft 21 to rotate. Under the action of the cross lever assembly 213, the piston 212 moves away from the grille 13, allowing water to enter the water storage chamber 11. The housing 1 sinks to the bottom of the pool, and the vacuum cleaner 15 removes the dirt from the bottom of the water. When the housing 1 needs to move forward, the drive unit rotates forward, causing the drive gear 262 to mesh with the forward gear 271. When the half gear 272 meshes with the rack 281, it drives the lifting plate 28 to descend. When the half gear 272 disengages from the rack 281, the lifting plate 28 rises under the action of the spring. Under the action of the eccentric rod 292, it drives several connecting shafts 29 to rotate synchronously, and the rear fan blade 293 rotates to provide forward power for the housing 1. When the tank 1 needs to turn, the drive gear 262 meshes with the left-turning gear 231 or the right-turning gear 241, thereby driving the side fan blade 25 to rotate and complete the turning. After the sludge suction is completed, the drive gear 262 meshes with the floating gear 22, causing the piston 212 to move towards the grid 13, thereby forming a cavity in the water storage chamber 11. Under the action of buoyancy, the tank 1 floats to the water surface. By adjusting the volume ratio of the water storage chamber 11 to the sludge storage chamber 12, the buoyancy provided when the inside of the water storage chamber 11 is a cavity can make the tank 1 float to the water surface.

[0032] This utility model provides an underwater dredging robot, which has the following advantages:

[0033] 1. By setting up water storage chambers and sludge storage chambers, the buoyancy is used to complete the rising and sinking of the tank, and it can automatically complete the forward movement and turning of the tank, ensuring good sludge removal effect.

[0034] 2. This utility model only requires one driving component to operate, which reduces the weight of the device and the manufacturing cost, making it easy to use and promote.

[0035] In summary, the beneficial effects of this utility model are: it can control the height of the container through buoyancy, and can automatically complete the forward movement and turning of the container, thus ensuring a good dredging effect.

[0036] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
