Description

Technical Field

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

[0002] Underwater cleaning robots With the continuous development and utilization of marine resources and the increasing attention paid to the quality of the water environment, underwater cleaning work has become increasingly important, and underwater cleaning robots need to face a series of technical challenges. First, due to the complexity and uncertainty of the underwater environment, the robot needs to have a high degree of autonomous navigation and obstacle avoidance capabilities to ensure that it does not collide with obstacles during the cleaning process. Secondly, due to the influence of underwater pressure and water flow, the robot's cleaning device needs to be designed to be strong and flexible enough to adapt to changes in different water depths and water flow speeds. In addition, the robot also needs to have a strong cleaning ability to effectively remove garbage and sediments on the bottom of the water.

[0003] The existing roller brush of the underwater cleaning robot is generally arranged at the front end of the robot, and is cylindrical in shape. The roller brush contacts the ground and rotates around its own axis to roll the garbage into the vicinity of the water suction port of the underwater cleaning robot.

[0004] However, the roller brush is usually fixed and lacks adaptability to different ground conditions and garbage conditions. When encountering uneven ground or high piles of garbage, the roller brush is easy to collide with obstacles, which may not only damage the roller brush itself, but also affect the overall performance and cleaning effect of the robot.

[0005] Secondly, traditional cleaning robots often have difficulty effectively compacting sheet-like impurities, such as paper or thin plastic sheets, when handling them. These impurities are easily drawn into the rotating brush and form eddies, causing the impurities to fly everywhere, which not only reduces cleaning efficiency, but also may cause secondary pollution, increasing the difficulty of subsequent cleaning.

[0006] To this end, we proposed a cleaning robot that introduces an adaptive adjustment component to enable the roller brush to adjust adaptively according to the ground and garbage conditions, thereby avoiding collisions with obstacles and effectively handling flaky impurities. This design can not only improve the working efficiency and cleaning effect of the cleaning robot, but also reduce secondary pollution and subsequent cleaning difficulties, bringing users a more convenient and efficient cleaning experience. Utility Model Content

[0007] The purpose of this utility model is to provide a cleaning robot, which can not only prevent the roller brush from colliding with obstacles and causing damage, but also improve the working efficiency and cleaning effect of the cleaning robot, and reduce secondary pollution and the difficulty of subsequent cleaning.

[0008] The technical solutions adopted in this utility are as follows:

[0009] A cleaning robot comprises a robot body, wherein the robot body is provided with a groove, an adaptive adjustment component is arranged inside the groove, and a roller brush is arranged on the adaptive adjustment component;

[0010] The adaptive adjustment component comprises two slide grooves provided on the inner wall of the groove, a fixed shaft is fixedly provided inside the slide groove, a spring and a slider are sleeved on the fixed shaft, the spring is provided on the top of the slider, the width of the slider is greater than the width of the slide groove, the rotating roller brush is provided on the slider, and a first arc frame is provided on one side of the slider, and a first adaptive pulley is installed on the end of the first arc frame away from the slider;

[0011] A support rod is arranged between the two first arc-shaped frames, a plurality of second arc-shaped frames are arranged on the support rod, and a second adaptive pulley is installed at one end of the second arc-shaped frame away from the support rod.

[0012] Furthermore, the robot body is provided with a water suction port, a filter box placement slot, a water suction pipe and a drainage pump, the water suction port is connected with the filter box placement slot, a filter box is arranged inside the filter box placement slot, and the filter box placement slot is connected with the water suction pipe, and the drainage pump is arranged on the water suction pipe.

[0013] Furthermore, a water inlet is provided at the bottom of the filter box.

[0019] 2. When encountering flaky impurities, the second adaptive pulley will press them to avoid the formation of eddy currents during the rotation of the roller brush, thereby preventing impurities from flying around and ensuring the orderly progress of the cleaning process.

[0027] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0028] like Figure 1-5 As shown, the technical solution adopted by the utility model is as follows: a cleaning robot comprises a robot body 1, a groove 2 is provided on the robot body 1, an adaptive adjustment component is arranged inside the groove 2, and a roller brush 3 is arranged on the adaptive adjustment component;

[0029] The adaptive adjustment component includes two slide grooves 4 provided on the inner wall of the groove 2, a fixed shaft 5 is fixedly provided inside the slide groove 4, a spring 6 and a slider 7 are sleeved on the fixed shaft 5, a spring 6 is provided on the top of the slider 7, the width of the slider 7 is greater than the width of the slide groove 4, a rotating roller brush 3 is provided on the slider 7, and a first arc frame 8 is provided on one side of the slider 7, and a first adaptive pulley 9 is installed on the end of the first arc frame 8 away from the slider 7;

[0030] A support rod 10 is arranged between the two first arc-shaped frames 8 , a plurality of second arc-shaped frames 11 are arranged on the support rod 10 , and a second adaptive pulley 12 is installed at one end of the second arc-shaped frame 11 away from the support rod 10 .

[0031] Its working principle is as follows: first, the cleaning robot is placed in water, and the robot body 1 starts to work. Its core component, the roller brush 3, starts to rotate, and uses its powerful cleaning ability to effectively remove all kinds of garbage and stains on the ground. The removed garbage and stains are then absorbed and processed by the internal system of the robot body 1. However, when there are uneven areas on the ground or the garbage is piled up high, the traditional fixed roller brush 3 often collides with these obstacles. Over time, the roller brush 3 is easily damaged. The unique design of the utility model can effectively avoid this problem. When the roller brush 3 encounters uneven or high garbage, it first contacts the first adaptive pulley 9 and the second adaptive pulley 12. These pulleys can slide adaptively along the contour of the obstacle instead of directly colliding with the roller brush 3. When the pulleys contact and move with the obstacle, they will drive the first arc frame 8 and the second arc frame 11 to make corresponding adjustments. The movement of the first arc frame 8 will further affect the slider 7 connected to it. The slider 7 slides on the fixed shaft 5. This sliding mechanism enables the roller brush 3 to be adaptively adjusted according to the unevenness of the ground or the height of the garbage accumulation. Through this adjustment, the roller brush 3 can always maintain a height suitable for the ground or the surface of the garbage pile, thereby effectively avoiding collision with it. When encountering flaky impurities, the second adaptive pulley 12 will intelligently press them, thereby avoiding the formation of eddy currents during the rotation of the roller brush 3, thereby preventing impurities from flying around, ensuring the orderly progress of the cleaning process. Through this mechanism, not only the cleaning efficiency is improved, but also the secondary pollution and the difficulty of subsequent cleaning are effectively reduced.

[0032] The slider 7 is matched with the slide groove 4. Matching here means that the slider 7 is very stable when moving in the slide groove 4 without getting stuck, which indirectly leads to the adjustment of the adaptive adjustment component.

[0033] Among them, the robot body 1 is provided with a water suction port 13, a filter box placement groove 1414, a water suction pipe 15 and a drainage pump 16, the water suction port 13 is connected with the filter box placement groove 1414, a filter box 17 is arranged inside the filter box placement groove 1414, and the filter box placement groove 1414 is connected with the water suction pipe 15, and the water suction pipe 15 is provided with a drainage pump 16.

[0034] People first place the filter box 17 in the filter box placement groove 1414, and then start the drainage pump 16. The drainage pump 16 generates suction, allowing impurities to enter the filter box 17 through the water suction port 13. After being filtered by the filter box 17, the impurities remain in the filter box 17, and water is discharged through the suction pipe 15 and the drainage pump 16.

[0035] A water inlet 18 is provided at the bottom of the filter box 17, and the length of the water inlet 18 is less than the length of the water suction port 13. This arrangement can generate an impact force when water enters the water inlet 18 from the water suction port 13. The impact force will impact the inner wall of the filter box 17, thereby preventing the filter box 17 from being blocked.

[0036] At the same time, a sealing cover is hinged at the water inlet 18. When water enters, suction is generated to open the sealing cover. When there is no suction, the sealing cover returns to its original position for sealing. This belongs to the prior art and will not be described in detail here.

[0037] The robot body 1 is an underwater cleaning robot, which includes:

[0038] 1. Controller module: This is the "brain" of the robot, responsible for overall control and decision-making. It usually uses a high-performance microprocessor or processor, responsible for receiving and processing data from various sensors, and controlling the movement and operation of the robot.

[0039] 2. Sensor module: includes various sensors, such as depth sensor, distance sensor, image sensor, etc. These sensors are used to sense the surrounding environment and status, and provide the controller with necessary information so that the robot can make correct decisions.

[0040] 3. Power module: Provides a stable power supply for the robot. Due to the special underwater environment, the power module usually needs to be waterproof and anti-corrosion treated.

[0041] 4. Communication module: used to communicate with the ground or other equipment, transmit data or receive control instructions.

[0042] 5. Navigation and positioning modules: These modules enable the robot to autonomously navigate and position itself in an underwater environment to ensure that it can accurately reach the designated cleaning area.

[0043] These modules are necessary modules for the underwater cleaning robot and are all existing technologies, so they will not be described in detail here.

[0044] The robot body 1 is provided with walking wheels, and tracks are provided on the walking wheels. The conveying is performed through the tracks, so that the friction force can be increased and the robot can walk smoothly.

[0045] It should be noted that: the walking wheel is driven by a waterproof motor (not shown in the figure), the waterproof motor is electrically connected to the controller inside the robot body 1, and the walking wheel is driven to move by the waterproof motor.

[0046] A heating plate is provided inside the water suction pipe 15, and the heating plate is electrically connected to the controller. The heating plate will not work during underwater cleaning. After cleaning, when the robot body 1 is taken out of the water, water droplets will remain inside it. At this time, the heating plate is started, and the drainage pump 16 is reversed to draw air, thereby drying the inside, so that it can be dried quickly to prevent water leakage.

[0047] The working principle of the utility model is as follows: first, the cleaning robot is placed in water, and the robot body 1 starts to work. Its core component, the roller brush 3, starts to rotate, and uses its powerful cleaning ability to effectively remove all kinds of garbage and stains on the ground. The removed garbage and stains are then absorbed and processed by the internal system of the robot body 1. However, when there are uneven areas on the ground or the garbage is piled up high, the traditional fixed roller brush 3 often collides with these obstacles. In the long run, the roller brush 3 is easily damaged. The unique design of the utility model can effectively avoid this problem. When the roller brush 3 encounters uneven or high garbage, it first contacts the first adaptive pulley 9 and the second adaptive pulley 12. These pulleys can slide along the contour of the obstacle adaptively instead of directly colliding with the roller brush 3. When the pulleys contact and move with the obstacle, they will drive the first arc frame 8 and the second arc frame 11 to make corresponding adjustments. The movement of the first arc frame 8 will further affect the slider 7 connected to it. The slider 7 slides on the fixed shaft 5. This sliding mechanism enables the roller brush 3 to be adaptively adjusted according to the unevenness of the ground or the height of the garbage accumulation. Through this adjustment, the roller brush 3 can always maintain a height suitable for the ground or the surface of the garbage pile, thereby effectively avoiding collision with it. When encountering flaky impurities, the second adaptive pulley 12 will intelligently press them, thereby avoiding the formation of eddy currents during the rotation of the roller brush 3, thereby preventing impurities from flying around, ensuring the orderly progress of the cleaning process. Through this mechanism, not only the cleaning efficiency is improved, but also the secondary pollution and the difficulty of subsequent cleaning are effectively reduced.

[0048] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
