Description

Technical Field

[0001] This utility model belongs to the field of cleaning robot technology, specifically relating to a water supply and drainage device for a cleaning robot. Background Technology

[0002] In municipal or industrial pipelines, cleaning robots are frequently used to clean the inner walls of pipes. By increasing the cleanliness of the inner walls, the flow of media in the pipes is improved, preventing blockages. In addition, for common blockages in water supply and drainage pipes, such as silt, debris, oil, scale, and microbial slime, robots use tools such as robotic arms, high-pressure water guns, and rotating brushes mounted on their front ends to powerfully flush or physically scrape away the blockages from the inner walls of the pipes, restoring the inner diameter of the pipes and improving water flow efficiency.

[0003] However, as the cleaning robot moves inside the pipe, the water supply and drainage pipe also needs to be continuously extended into the pipe. When the water supply and drainage pipe is unwound for a long time, the friction between the water supply and drainage pipe and the pipe being cleaned increases. This requires the cleaning robot to increase its moving power in order to drag the water supply and drainage pipe. This not only increases the load weight of the cleaning robot when it moves, but also easily causes the aging of the driving components of the cleaning robot. Utility Model Content

[0004] The purpose of this invention is to provide a water supply and drainage device for a cleaning robot, which can reduce the friction between the water supply and drainage pipe and the pipe being cleaned, making it easier for the cleaning robot to penetrate deep into the pipe for cleaning, while also reducing the load capacity of the cleaning robot's drive components and extending the service life of the cleaning robot.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A water supply and drainage device for a cleaning robot includes two arc-shaped plates that are hinged together to form a ring structure. Several ball bearings are movably connected to the sidewalls of the arc-shaped plates. An elastic clamping component is provided on the opposite sidewall of each arc-shaped plate. A locking component is provided at the end of each arc-shaped plate away from the hinge position.

[0007] The elastic clamping assembly includes a clamping plate, which is arc-shaped. Two limiting rods are fixedly connected to the side walls of the clamping plate that are far apart from each other. The other end of each limiting rod is movably connected to the arc-shaped plate. A spring is sleeved on the side wall of each limiting rod.

[0008] Two limiting grooves are provided on the side wall of the arc-shaped plate, and the limiting rod is slidably connected to the limiting groove.

[0009] Several anti-slip protrusions are fixedly connected to the opposite side wall of the clamp, and the anti-slip protrusions are conical in shape.

[0010] The locking assembly includes a connecting plate fixedly connected to the side wall of the arc-shaped plate near the end face. A plug rod is fixedly connected to the bottom surface of the upper connecting plate, and an elongated hole is opened on the top surface of the lower connecting plate. The plug rod is inserted into the elongated hole, and a limit member is provided on the side wall of the plug rod.

[0011] The limiting component includes several positioning holes formed on the side wall of the insertion rod, and a cotter pin is inserted into one of the positioning holes.

[0012] The sidewall of the arc-shaped plate is provided with several spherical grooves, and the ball bearings are tactilely connected to the spherical grooves.

[0013] The technical effects achieved by this utility model are as follows:

[0014] The cleaning robot water supply and drainage device of this utility model can reduce the friction between the water supply and drainage pipe and the pipe to be cleaned by the cooperation of the arc plate, elastic clamping component and locking component, so as to facilitate the cleaning robot to go deep into the pipe for cleaning. At the same time, it reduces the load capacity of the cleaning robot's drive components and extends the service life of the cleaning robot. Attached Figure Description

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-5 As shown, a water supply and drainage device for a cleaning robot includes two arc-shaped plates 1, which are hinged together to form a ring structure. A pipe 14 is provided between the two arc-shaped plates 1, and the pipe 14 is used to connect to the cleaning robot to provide water supply. Several ball bearings 2 are movably connected to the side walls of the arc-shaped plates 1 respectively. An elastic clamping component is provided on the opposite side wall of the arc-shaped plates 1. A locking component is provided at the end of the two arc-shaped plates 1 away from the hinge position.

[0024] like Figure 2 As shown, the elastic clamping assembly includes a clamping plate 3, which is arc-shaped. Two limiting rods 4 are fixedly connected to the side walls of the clamping plate 3 that are far apart from each other. The other end of each limiting rod 4 is movably connected to the arc-shaped plate 1. A spring 5 is sleeved on the side wall of each limiting rod 4. Two limiting grooves 6 are formed on the side wall of the arc-shaped plate 1, and the limiting rods 4 are slidably connected to the limiting grooves 6. The limiting grooves 6 can be used to limit the limiting rods 4 and control the ultimate extension and contraction of the limiting rods 4.

[0025] Several anti-slip protrusions 7 are fixedly connected to the opposite side wall of the clamping plate 3. The anti-slip protrusions 7 are conical in shape.

[0026] The spring 5 is used to clamp the pipe 14, and it can also adapt to pipes 14 of different diameters, making it widely and flexibly applicable. In addition, since the pipes 14 used with the cleaning robot are mostly flexible hoses with high surface friction, the anti-slip protrusions 7 can be set to make the clamping plate 3 fit against the surface of the pipe 14, thereby increasing friction and improving stability.

[0027] like Figure 4 and Figure 5 As shown, the locking assembly includes a connecting plate 8 fixedly connected to the side wall of the arc plate 1 near the end face. A plug rod 9 is fixedly connected to the bottom surface of the upper connecting plate 8, and an elongated hole 10 is opened on the top surface of the lower connecting plate 8. The plug rod 9 is inserted into the elongated hole 10, and a limit member is provided on the side wall of the plug rod 9.

[0028] The limiting component includes several positioning holes 11 formed on the side wall of the insertion rod 9, and a cotter pin 12 is inserted into one of the positioning holes 11.

[0029] The locking assembly adopts a relatively simple plug-in method. During the pipeline cleaning process, since the cleaning robot is in a continuous moving state, in order to facilitate the quick fixation of the arc plate 1 to the pipe 14, the operator can quickly connect the arc plate 1 to the pipe 14 at one end of the pipeline and limit it through the cotter pin 12. It has the characteristics of simple operation, low cost and strong replaceability.

[0030] like Figure 1As shown, the side wall of the arc plate 1 has several spherical grooves 13, and the ball bearings 2 are rolled in connection with the spherical grooves 13. The spherical grooves 13 are used to limit the movement of the ball bearings 2, so that the ball bearings 2 can roll in the spherical grooves 13. Even if the pipe 14 causes the arc plate 1 to flip, it will not affect the contact between the ball bearings 2 and the pipe. At the same time, it can also play a role in auxiliary support and movement.

[0031] The working principle of this utility model is as follows: First, the two arc-shaped plates 1 are in the open state. Then, the pipe 14 is placed between the two side clamps 3. Then, the arc-shaped plates 1 are closed. At the same time, the insertion rod 9 is inserted into the long hole 10 and the two side arc-shaped plates 1 are pressed down. The clamps 3 are pressed tightly against the surface of the pipe 14. At the same time, the spring 5 is compressed. The elastic force of the spring 5 is used to make the clamps 3 press tightly against the surface of the pipe 14. Then, the cotter pin 12 is inserted into the appropriate positioning hole 11 to complete the fixing of the arc-shaped plates 1.

[0032] When the pipe 14 goes deep into the pipeline being cleaned, the arc plate 1 can not only support the pipe 14, but also reduce the friction between the arc plate 1 and the pipeline by using the ball bearing 2, making it easier for the cleaning robot to move the pipe 14.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
