[0001] The utility model relates to the technical field of unmanned cleaning vehicles, in particular to a water filling device for unmanned cleaning vehicles. Background Technique

[0002] A cleaning vehicle is a new type of efficient cleaning equipment that integrates road cleaning, garbage collection and transportation. With the rapid development of information technology, an unmanned cleaning vehicle has emerged, which can further reduce the sanitation cost.

[0003] However, the existing unmanned cleaning vehicles generally have a water spraying function, but the water tank of the cleaning vehicle is small. After spraying water for a period of time, the water tank becomes empty. In the prior art, manual water filling is generally adopted. In this case, manual water filling is frequent. In addition, if the manual water filling is not timely enough, it is easy to cause the cleaning vehicle to lack water, which will affect the cleaning progress. Content of the Utility Model

[0004] The purpose of the utility model is to provide a water filling device for an unmanned cleaning vehicle to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] A water filling device for an unmanned cleaning vehicle includes a water injection cabinet and a cleaning vehicle main body. At both ends of the bottom of the front surface of the water injection cabinet, limit plates are provided. Inside the two limit plates is the cleaning vehicle main body. On the top of the cleaning vehicle main body is a cleaning vehicle water tank. At the front end of the top of the cleaning vehicle main body is a connecting plate. On the front surface of the connecting plate is fixedly connected a water pumping tank. At the center of the back surface of the water pumping tank is a water injection pipe. The other end of the water injection pipe passes through the connecting plate and is connected to the top of the cleaning vehicle water tank. At the center of the front surface of the water pumping tank is a first connecting water pipe. The other end of the first connecting water pipe is provided with a first connecting plate. The first connecting plate is connected to a second connecting plate by a magnetic attraction method. On the back surface of the second connecting plate is a second connecting water pipe. The other end of the second connecting water pipe is connected to the front surface of the water injection cabinet.

[0007] Preferably, a liquid level sensor is arranged inside the cleaning vehicle water tank, and the top of the liquid level sensor is fixedly connected to the top of the cleaning vehicle water tank.

[0008] Preferably, a first extension plate is arranged on the surface of the first connecting water pipe, and a plurality of fixing columns are arranged on the surface of the first extension plate.

[0009] Preferably, a second extension plate is arranged on the surface of the second connecting water pipe, and a fixing sleeve is arranged on the front surface of the second extension plate.

[0010] Preferably, the lengths of different said fixing sleeves are different.

[0011] Preferably, between the fixing posts and the fixing sleeves at the same horizontal plane, they are connected by a snap - fit connection method.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] For a water - adding device for an unmanned cleaning vehicle of the present utility model, the liquid level height in the cleaning vehicle water tank is real - time monitored by a liquid level sensor in the cleaning vehicle water tank. When the liquid level is relatively low, a certain signal will be transmitted to the controller, and the controller will control the cleaning vehicle to move to the water - injection cabinet for water - adding operation. During the process of the cleaning vehicle main body moving towards the water - injection cabinet, it will reach the limit plate, and the limit plate will limit the cleaning vehicle main body to prevent the connection between the first connecting plate and the second connecting plate from being insufficiently tight, thereby causing water leakage during the water - adding process.

[0014] For a water - adding device for an unmanned cleaning vehicle of the present utility model, a first extension plate and a second extension plate are respectively arranged on the surfaces of the first connecting water pipe and the second connecting water pipe. A fixing post is arranged on the surface of the first extension plate, and a fixing sleeve is arranged on the surface of the second extension plate. Among them, the lengths of the fixing sleeves are different. During the process of the cleaning vehicle main body moving towards the water - injection cabinet, the position of the cleaning vehicle main body will be determined after each section of movement. When there is a position deviation, when the fixing post is inserted into the fixing sleeve, the fixing post will physically correct the cleaning vehicle main body to prevent the connection between the first connecting plate and the second connecting plate from being insufficiently tight, thereby causing water leakage during the water - adding process.

[0021] Please refer to Figure 1-2 , the present invention provides a technical solution:

[0022] A water filling device for an unmanned cleaning vehicle, including a water injection cabinet 1 and a cleaning vehicle main body 3. At both ends of the bottom of the front surface of the water injection cabinet 1, there are provided limit plates 2. Inside the two limit plates 2, there is a cleaning vehicle main body 3. On the top of the cleaning vehicle main body 3, there is a cleaning vehicle water tank 4. At the front end of the top of the cleaning vehicle main body 3, there is a connecting plate 7. On the front surface of the connecting plate 7, there is a fixed connection with a water pumping tank 8. At the center of the back surface of the water pumping tank 8, there is a water injection pipe 6. The other end of the water injection pipe 6 passes through the connecting plate 7 and is connected to the top of the cleaning vehicle water tank 4. At the center of the front surface of the water pumping tank 8, there is a first connecting water pipe 9. The other end of the first connecting water pipe 9 is provided with a first connecting plate 10. The first connecting plate 10 is connected to a second connecting plate 14 by magnetic attraction. On the back surface of the second connecting plate 14, there is a second connecting water pipe 13. The other end of the second connecting water pipe 13 is connected to the front surface of the water injection cabinet 1.

[0023] Furthermore, inside the cleaning vehicle water tank 4, there is a liquid level sensor 5. The top of the liquid level sensor 5 is fixedly connected to the top of the cleaning vehicle water tank 4.

[0024] Further, a first extension plate 11 is provided on the surface of the first connecting water pipe 9, and a plurality of fixing columns 12 are provided on the surface of the first extension plate 11.

[0025] Further, a second extension plate 16 is provided on the surface of the second connecting water pipe 13, and a fixing sleeve 15 is provided on the front surface of the second extension plate 16.

[0026] Further, the lengths of different fixing sleeves 15 are different.

[0027] Further, the fixing columns 12 and the fixing sleeves 15 on the same horizontal plane are connected by a snap connection method.

[0028] Working principle: For a water filling device for a driverless sweeper of the present invention, the liquid level sensor 5 in the water tank 4 of the sweeper monitors the liquid level height in the water tank of the sweeper in real time. When the liquid level is relatively low, a certain signal will be transmitted to the controller, and the controller will control the sweeper body 3 to move to the water injection cabinet for water filling operation. During the process of the sweeper body 3 moving towards the water injection cabinet 1, it will reach the limit plate 2. The height of the limit plate 2 is much longer than that of the sweeper body 3, and the width between the limit plates 2 matches the width of the sweeper body 3. During the movement of the sweeper body 3, the limit plate 2 will limit the sweeper body 3. After the sweeper body 3 moves to a suitable position, the first connecting plate 10 will be connected to the second connecting plate 14 through a magnetic attraction structure to prevent the connection between the first connecting plate 10 and the second connecting plate 14 from being insufficiently tight due to offset during the movement process, thereby causing water leakage during the water filling process.

[0029] For a water filling device for a driverless sweeper of the present invention, a first extension plate 11 and a second extension plate 16 are respectively provided on the surfaces of the first connecting water pipe 9 and the second connecting water pipe 13. A fixing column 12 is provided on the surface of the first extension plate 11, and a fixing sleeve 15 is provided on the surface of the second extension plate 16. The lengths of the fixing sleeves are different. During the process of the sweeper body 3 moving towards the water injection cabinet 1, the position of the sweeper body 3 will be determined after each section of movement. When there is a position offset, it will be very difficult for the fixing column 12 to be inserted into the fixing sleeve 15. However, at this time, the sweeper body 3 still has a tendency to move towards the water injection cabinet 1, and a certain force will be generated in the offset direction. After the force straightens the sweeper body 3, it will be very simple to insert the fixing column 12 into the fixing sleeve 15, so that the moving direction of the sweeper body 3 will not deviate.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
