Description

Technical Field

[0001] The utility model relates to the technical field of underwater cleaning robots, and more specifically, to a novel underwater cleaning robot. Background Art

[0002] When the swimming pool is in use, impurities such as leaves, branches, sand, and household garbage will fall into it, polluting the swimming pool and affecting the water quality. The traditional way to clean a swimming pool is by manual cleaning, but manual cleaning is time-consuming, labor-intensive, and costly. The current cleaning method is mainly by intelligent underwater robots. Intelligent underwater robots mainly use built-in filtering components and water pumps to suck in swimming pool water, filter garbage, and then discharge swimming pool water to clean the swimming pool. After cleaning, the underwater robot can return to the ground from underwater by climbing a slope or a wall.

[0003] When the underwater cleaning robot is climbing a wall or a slope, it may fall due to the influence of gravity. At this time, the underwater cleaning robot needs to increase the speed of the water pump to obtain greater propulsion. However, when the pump speed is increased, the underwater cleaning robot will also generate excessive suction, thereby sucking in more water at the water inlet, resulting in increased driving resistance of the underwater cleaning robot, slow driving, and increased power consumption.

[0012] According to a novel underwater cleaning robot of the utility model, when the rotation speed of the water pump in the body is less than the set value, the buoyancy of the floating block is greater than the force exerted by the water outside the body on the pressure relief baffle;

[0013] When the rotation speed of the water pump in the machine body is greater than the set value, the buoyancy of the floating block is smaller than the force exerted by the water outside the machine body on the pressure relief baffle.

[0014] According to a novel underwater cleaning robot of the utility model, an elastic member is further arranged between the floating block and the limiting part, and the elastic member drives the floating block and the pressure relief baffle to rise through elastic force, thereby assisting the pressure relief baffle to close the second water inlet.

[0015] According to a novel underwater cleaning robot of the utility model, when the sum of the buoyancy exerted on the floating block and the elastic force exerted on the floating block by the elastic member is greater than the force exerted by the water outside the body on the pressure relief baffle, the second water inlet is closed;

[0016] When the sum of the buoyancy exerted on the floating block and the elastic force exerted on the floating block by the elastic member is smaller than the force exerted on the pressure relief baffle by the water outside the body, the second water inlet is opened.

[0017] According to a novel underwater cleaning robot of the utility model, the elastic member is a spring.

[0018] According to a novel underwater cleaning robot of the utility model, the guide mechanism includes two groups, and the two groups of guide mechanisms are respectively arranged on both sides of the second water inlet.

[0025] The underwater cleaning robot of the utility model is provided with a pressure relief component, which includes a second water inlet, a pressure relief baffle and a guide mechanism arranged on the top of the machine body. When the rotation speed of the water pump in the machine body is less than a set value, the force of the guide mechanism on the pressure relief baffle is greater than the force of the water outside the machine body on the pressure relief baffle, thereby causing the guide mechanism to move up to assist the pressure relief baffle in closing the second water inlet, so that the underwater cleaning robot can travel on a plane; when the machine body travels on a slope, the machine body needs to increase the rotation speed of the water pump to obtain a greater propulsion force. At this time, a greater negative pressure is formed in the machine body, thereby driving more water outside the machine body to act on the pressure relief baffle. When the rotation speed of the water pump in the machine body is greater than a set value, the force of the guide mechanism on the pressure relief baffle is less than the force of the water outside the machine body on the pressure relief baffle, thereby causing the pressure relief baffle and the guide mechanism to move downward to open the second water inlet, and water outside the machine body enters the machine body from the second water inlet to meet the high-speed operation of the water pump, while generating upward suction, reducing the driving resistance of the machine, and facilitating the underwater cleaning robot to achieve climbing work.

[0034] Example 1

[0035] like Figure 1As shown, this embodiment discloses a novel underwater cleaning robot, including a body 100, wherein wheels 110 and a first water inlet 200 are provided at the bottom of the body 100, a water outlet 300 and a water pump 400 for auxiliary drainage are provided at the rear side of the body 100, a pressure relief assembly 500 and a filter assembly 600 for collecting garbage are provided inside the body 100, and the filter assembly 600 is connected to the first water inlet 200. When the body 100 walks on the bottom of the water for cleaning, under the action of the water pump 400, external water and garbage enter the body 100 from the first water inlet 200, and the water entering the body 100 is discharged from the water outlet 300 under the action of the water pump 400, and can provide propulsion for the forward movement of the body 100. The garbage entering the body 100 is blocked by the filter assembly 600, and is collected in the filter assembly 600, so as to achieve underwater cleaning. After the underwater cleaning work is completed, the machine body 100 can move from the bottom of the water to the land by climbing the slope, so that the staff can remove the garbage in the filter assembly 600. The filter assembly 600 can be installed in the machine body 100 in a fixed installation manner, or can be embedded in the machine body 100 in a detachable installation manner.

[0036] Furthermore, the pressure relief assembly 500 is disposed on the inner side of the top of the body 100 to assist the robot in climbing. Specifically, the pressure relief assembly 500 includes a second water inlet 510, a pressure relief baffle 520 and a guide mechanism 530. The pressure relief baffle 520 is disposed below the second water inlet 510 to close the second water inlet 510. The guide mechanism 530 is connected to the pressure relief baffle 520 and provides an upward force to the pressure relief baffle 520 to assist the pressure relief baffle 520 in closing the second water inlet 510. When the body 100 is traveling on a plane, the speed of the water pump 400 in the body 100 is less than the set value, and the force of the guide mechanism 530 on the pressure relief baffle 520 is greater than the force of the water outside the body 100 on the pressure relief baffle 520. , thereby causing the pressure relief baffle 520 to move upward and closing the second water inlet 510; when the machine body 100 travels on a slope, the rotation speed of the water pump 400 increases, and a negative pressure is formed in the machine body 100. When the rotation speed of the water pump 400 is greater than the set value, a greater negative pressure is formed in the machine body 100, so that the force of the guide mechanism 530 on the pressure relief baffle 520 is less than the force of the water outside the machine body 100 on the pressure relief baffle 520, thereby causing the guide mechanism 530 to move downward, the second water inlet 510 is opened, and the water outside the machine body 100 enters the machine body 100 from the second water inlet 510, thereby reducing the driving resistance of the machine body 100.

[0037] Specifically, when the machine body 100 is climbing a slope, it is necessary to increase the speed of the water pump 400 to obtain a greater propulsion force. At this time, a greater negative pressure is formed in the machine body 100, driving more water outside the machine body 100 to act on the pressure relief baffle 520, so that the force of the guide mechanism 530 on the pressure relief baffle 520 is less than the force of the water outside the machine body 100 on the pressure relief baffle 520, and finally the pressure relief baffle 520 and the guide mechanism 530 move downward, the second water inlet 510 is opened, and the water outside the machine body 100 enters the machine body 100 from the second water inlet 510 to meet the high-speed operation of the water pump 400, and the machine body 100 can generate upward suction, reduce the driving resistance of the robot, and facilitate the underwater cleaning robot to climb. In this way, the underwater cleaning robot will not increase the driving resistance of the underwater cleaning robot due to excessive suction generated at the first water inlet 200.

[0038] Combination Figure 2 and Figure 3 As shown, further, the guide mechanism 530 of the present embodiment includes a guide seat 531, a guide column 532, a float 533 and a limit piece 534; wherein, the guide seat 531 is arranged on the top inner side of the body 100, one end of the guide column 532 is fixed on the guide seat 531, and the other end is connected to the limit piece 534, the pressure relief baffle 520 and the float 533 are arranged through the guide column 532, and the float 533 is located below the pressure relief baffle 520, the water in the body 100 provides buoyancy to the float 533, and the float 533 drives the pressure relief baffle 520 to rise through the buoyancy, thereby assisting the pressure relief baffle 520 to close the second water inlet 510.

[0039] That is, the float 533 and the pressure relief baffle 520 of this embodiment are movably installed on the guide column 532. When the body 100 travels on a plane, the buoyancy of the float 533 is greater than the force of the water outside the body 100 on the pressure relief baffle 520, thereby closing the second water inlet 510 to avoid affecting the travel of the body 100 on the water surface. When the machine body 100 is traveling on a slope, the machine body 100 requires a greater propulsion force to achieve climbing, so the rotation speed of the water pump 400 needs to be increased. At this time, a greater negative pressure is formed inside the machine body 100, driving more water outside the machine body 100 to act on the pressure relief baffle 520. When the rotation speed of the water pump 400 is greater than the set value, the buoyancy of the float 533 is less than the force of the water outside the machine body 100 on the pressure relief baffle 520. The float 533 and the pressure relief baffle 520 move downward under the action of external water, thereby opening the second water inlet 510, and external water enters the machine body 100 from the second water inlet 510, thereby providing additional water flow inside the machine body 100 to meet the operation of the high-speed water pump 400 and generate upward suction to reduce the driving resistance of the robot.

[0040] Furthermore, in order to better close the second water inlet 510, an elastic member 535 is further provided between the floating block 533 and the limiting portion, and the elastic member 535 drives the floating block 533 and the pressure relief baffle 520 to rise by elastic force, thereby assisting the pressure relief baffle 520 to better close the second water inlet 510. In this embodiment, the elastic member 535 is a spring.

[0041] Specifically, when the sum of the buoyancy of the float 533 and the elastic force applied by the elastic member to the float 533 is greater than the force of the water outside the body 100 on the pressure relief baffle 520, the second water inlet 410 is closed, and the body 100 travels on a plane; when the sum of the buoyancy of the float 533 and the elastic force applied by the elastic member to the float 533 is less than the force of the water outside the body 100 on the pressure relief baffle 520, the second water inlet 510 is opened, and the body 100 travels on a slope.

[0042] Furthermore, the guide mechanism 530 of this embodiment includes two groups, and the two groups of guide mechanisms 530 are respectively disposed on both sides of the second water inlet 510 .

[0043] Furthermore, the body 100 of the present embodiment is in the shape of a trolley as a whole, the first water inlet 200 and the second water inlet 510 are respectively arranged on the bottom and the roof of the trolley, and the water outlet 300 is arranged on the rear of the trolley.

[0044] In this technical solution, when the second water inlet 510 is opened, the gap between the second water inlet 510 and the pressure relief baffle 520 is relatively small, so garbage generally cannot enter the body 100 from the second water inlet 510, so the filter assembly 600 can only be arranged around the first water inlet 200.

[0045] Preferably, the second water inlet 510 is in a trumpet shape that gradually expands toward the inside of the machine body 100. Such a configuration helps to reduce the flow resistance of the water flow and reduce the operating power consumption.

[0046] Example 2

[0047] like Figure 4 As shown, the difference between this embodiment 2 and embodiment 1 is that, in order to better achieve the filtering effect, the filter component 600 is connected to the second water inlet 510, and the filter component 600 is arranged outside the pressure relief baffle 520 and the guide mechanism 530, that is, the filter component 600 filters the first water inlet 200 and the second water inlet 510 at the same time, thereby achieving a better filtering effect.

[0048] Obviously, the above embodiments of the utility model are only examples for clearly explaining the technical solution of the utility model, and are not intended to limit the specific implementation methods of the utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the claims of the utility model shall be included in the protection scope of the claims of the utility model.
