Description

Technical Field

[0001] This utility model relates to the technical field of water surface cleaning, and in particular to an automatic water surface cleaning machine with protective functions. Background Technology

[0002] With the rapid development of society and economy, people's lives have undergone a qualitative leap. Especially since the Industrial Revolution, people have paid too much attention to industrial and economic development and often neglected environmental protection. As a result, the quality of world water resources has continued to decline and the water environment has continued to deteriorate in recent years, causing a large amount of garbage to float on rivers, lakes and reservoirs. Garbage on the water surface is an important factor affecting the cleanliness of water bodies, and regularly cleaning up garbage on the water surface is an important and arduous task.

[0003] Currently, automatic water surface cleaning machines can be used to collect trash on the water surface. To use one, the machine is first placed in the water. Due to the buoyancy of the flotation device, the filter screen and filter cylinder of the filtration system float on the water. The pump is then activated, drawing water into the filter screen. The water then flows through the mesh of the filter screen and out of the filter cylinder, creating a continuous cycle. As the water flows into the filter screen, it carries trash from the surface into the screen, where it is collected and stored.

[0004] We have recently developed a multi-functional automatic water surface cleaning machine. When using this machine to collect debris from the water surface, first place it in the water. Due to the buoyancy generated by the floating device, the filter screen and filter cylinder of the filtration system will float on the water. Then, activate the pumping device; water will be drawn into the filter screen, then through the mesh, and finally out of the filter cylinder through the opening, ultimately being discharged through the main outlet. This allows for cleaning both in place and while moving, reducing costs.

[0005] However, our latest automatic water surface cleaning machine, which can clean both in place and while moving, is deformed when it collides with a wall or other object in the water. This causes the water pump to deform, which in turn causes the water outlet tube to deform and the direction of the water flow to change, making it impossible to accurately propel the device to move in the expected direction on the water surface. Utility Model Content

[0006] To address the problem that when the aforementioned device collides with a wall or other object in water, the pump will be deformed by the impact, leading to deformation of the device's outlet tube and a change in the direction of the water flow, thus preventing the device from accurately moving on the water surface in the intended direction, this utility model provides an automatic water surface cleaning machine with protective functions.

[0007] This utility model provides an automatic water surface cleaning machine with protective functions, adopting the following technical solution:

[0008] An automatic water surface cleaning machine with protective functions includes a sealed chamber and a water pumping device. A filter device is installed on the top of the water pumping device, and a protective cover is connected to the bottom of the filter device. The sealed chamber and the water pumping device are both located inside the protective cover, and the protective cover has main water outlets on both the front and rear sides.

[0009] The water pumping device includes a pumping shell and a pump. The pumping shell is installed on the top of the sealed chamber. The pumping shell and the filter device form a drainage chamber. The bottom of the filter device has an opening. The front and rear sides of the pumping shell are connected to the main water outlet cylinder.

[0010] By adopting the above technical solution, and by placing the protective cover on the outside of the sealed chamber and the water pumping device, when the cleaning machine collides with the wall or other objects in the water, the protective cover can prevent the sealed chamber and the water pumping device from being deformed by the impact, thereby preventing the main water outlet tube of the automatic water surface cleaning machine from deforming. This ensures the accuracy of the water flow direction from the main water outlet tube, and further enables the automatic water surface cleaning machine to move accurately on the water surface in the expected direction.

[0011] Optionally, the filtration device includes a filter cylinder mounted on top of the pump housing, and a filter screen is installed inside the filter cylinder.

[0012] By adopting the above technical solution, water will be drawn into the filter screen, and then the water will flow out of the filter cylinder through the mesh of the filter screen. During the process of the water flowing into the filter screen, it will bring the garbage on the water surface into the filter screen, making it convenient to collect the garbage.

[0013] Optionally, the main water outlet on the front side is directly opposite to the main water outlet cylinder on the front side, and the main water outlet on the rear side is directly opposite to the main water outlet cylinder on the rear side. The water flowing out of the two sets of main water outlet cylinders flows in opposite directions, and the water flowing out of the two sets of main water outlets flows in opposite directions.

[0014] By adopting the above technical solution, when the automatic water surface cleaning machine needs to move forward, the main water outlet on the front side is controlled to stop water flow, and water is controlled to flow out from the main water outlet on the rear side, and then from the main water outlet on the rear side of the protective cover, thus pushing the automatic water surface cleaning machine forward. When the automatic water surface cleaning machine needs to move backward, the main water outlet on the rear side is controlled to stop water flow, and water is controlled to flow out from the main water outlet on the front side, and then from the main water outlet on the front side of the protective cover, thus pushing the automatic water surface cleaning machine backward.

[0015] Optionally, the inner wall of the main water outlet cylinder on the front side is aligned with the inner wall of the main water outlet on the front side, and the inner wall of the main water outlet cylinder on the rear side is aligned with the inner wall of the main water outlet on the rear side.

[0016] By adopting the above technical solution, it is beneficial for water to flow smoothly from the main water outlet cylinder through the main water outlet.

[0017] Optionally, the outer wall of the main water outlet cylinder on the front side abuts against the inner wall of the protective cover, and the outer wall of the main water outlet cylinder on the rear side abuts against the inner wall of the protective cover.

[0018] By adopting the above technical solution, the main water outlet cylinder is prevented from shaking, and its stability is enhanced, thereby further ensuring the accuracy of the water flow direction from the main water outlet cylinder of the automatic water surface cleaner, and further enabling the automatic water surface cleaner to move accurately on the water surface.

[0019] Optionally, one-way valves are provided on both the front and rear sides of the protective cover, and both sets of one-way valves abut against the outer wall of the protective cover.

[0020] By adopting the above technical solution, when the main water outlet is not discharging water, the one-way valve covers the main water outlet; when the main water outlet is discharging water, the one-way valve is opened by the water flow from the main water outlet, thus ensuring the accuracy of the forward and backward directions of the automatic water surface cleaning machine.

[0021] Optionally, valve frames are provided on both the front and rear sides of the protective cover. The one-way valve on the front side is located inside the valve frame on the front side, and the outer periphery of the one-way valve on the front side is in clearance fit with the inner wall of the valve frame on the front side. The one-way valve on the rear side is located inside the valve frame on the rear side, and the outer periphery of the one-way valve on the rear side is in clearance fit with the inner wall of the valve frame on the rear side.

[0022] By adopting the above technical solution, the valve frame has a blocking effect on the one-way valve, which can prevent the one-way valves on the front and rear sides of the protective cover from tilting, thereby ensuring the coverage of the one-way valve on the main outlet and further ensuring the accuracy of the forward and backward directions of the automatic water surface cleaning machine.

[0023] Optionally, the pumping device further includes auxiliary water outlet cylinders located on the left and right sides of the pumping shell. The two sets of auxiliary water outlet cylinders are connected to the drainage chamber, and an auxiliary drainage port is provided on both the left and right sides of the protective cover.

[0024] By adopting the above technical solution, the pump delivers the water that reaches the drainage chamber. Part of the delivered water flows out from the main outlet pipe, and part of the water flows out from the auxiliary outlet pipe. The water flowing out from the auxiliary outlet pipe finally flows out from the auxiliary drain outlet.

[0025] Optionally, the bottom of the protective cover is provided with an auxiliary drainage outlet.

[0026] By adopting the above technical solution, the water flowing out of the auxiliary water outlet can also flow out from the auxiliary drain outlet 2, which speeds up the discharge of water from the auxiliary water outlet and further increases the flow rate of the automatic water surface cleaning machine.

[0027] Optionally, the pump includes two sets of motors, the body of each set of motors is installed inside the sealed chamber, the top of each set of motors is connected to a drive shaft, and an impeller is installed at one end of each set of drive shafts that extends into the pump casing.

[0028] By adopting the above technical solution, when the motor is working, it drives the impeller to rotate through the transmission shaft, and uses the centrifugal force generated when the impeller rotates to transport water.

[0029] In summary, this utility model has at least one of the following beneficial effects:

[0030] By placing a protective cover on the outside of the sealed chamber and the water pumping device, when the cleaning machine collides with a wall or other object in the water, the protective cover can prevent the sealed chamber and the water pumping device from being deformed by the impact, thereby preventing the main water outlet tube of the automatic water surface cleaning machine from deforming. This ensures the accuracy of the water flow direction from the main water outlet tube, and further enables the automatic water surface cleaning machine to move accurately on the water surface in the expected direction.

[0031] By setting two sets of one-way valves, when the main outlet is not discharging water, the one-way valve covers the main outlet. When water flows from the main outlet, the one-way valve is opened by the water flow from the main outlet, ensuring the accuracy of the automatic water surface cleaning machine's forward and backward directions. At the same time, the valve frame blocks the one-way valve, preventing it from tilting, thus ensuring the one-way valve's coverage of the main outlet and further guaranteeing the accuracy of the automatic water surface cleaning machine's forward and backward directions.

Detailed Implementation

[0038] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0039] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2 This utility model provides an embodiment of an automatic water surface cleaning machine with protective functions, including a sealed chamber 7 and a water pumping device. A filter device 2 is installed on the top of the water pumping device, and a protective cover 1 is connected to the bottom of the filter device 2. Both the sealed chamber 7 and the water pumping device are located inside the protective cover 1. Main water outlets 6 are provided on both the front and rear sides of the protective cover 1. One-way valves 3 are provided on both the front and rear sides of the protective cover 1, and both sets of one-way valves 3 abut against the outer wall of the protective cover 1. When no water is flowing from the main water outlet 6, the one-way valves 3 cover the main water outlet 6. When water flows from the main water outlet 6, the one-way valves 3 are opened by the water flow from the main water outlet 6, ensuring the accuracy of the automatic water surface cleaning machine's forward and backward directions.

[0040] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 and Figure 3 The protective cover 1 has valve frames 4 on both its front and rear sides. A front one-way valve 3 is located within the front valve frame 4, with its outer periphery fitting a clearance fit with the inner wall of the front valve frame 4. Similarly, a rear one-way valve 3 is located within the rear valve frame 4, with its outer periphery fitting a clearance fit with the inner wall of the rear valve frame 4. The valve frames 4 act as a barrier to the one-way valves 3, preventing them from tilting and ensuring their coverage of the main outlet 6. This further guarantees the accuracy of the automatic water surface cleaning machine's forward and backward directions.

[0041] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2 The water pumping device includes a pumping shell 8 and a pump. The filtration device 2 includes a filter cylinder 201, which is installed on top of the pumping shell 8. A filter screen 202 is installed inside the filter cylinder 201. Water is drawn into the filter screen 202 and then flows out of the filter cylinder 201 through the mesh of the filter screen 202 and the opening 5 of the filter cylinder 201. During the process of water flowing into the filter screen 202, it will bring garbage on the water surface into the filter screen 202, making it convenient to collect garbage.

[0042] Please refer to the attached diagram in the instruction manual. Figure 2 and Figure 4 The water-drawing shell 8 is installed on top of the sealed chamber 7, and the water-drawing shell 8 and the filter device 2 form a drainage chamber 11. The bottom of the filter device 2 has an opening 5. The front and rear sides of the water-drawing shell 8 are connected to the main water outlet cylinders 12. The main water outlet 6 on the front side is directly opposite to the main water outlet cylinder 12 on the front side, and the main water outlet 6 on the rear side is directly opposite to the main water outlet cylinder 12 on the rear side. The water flowing out of the two sets of main water outlet cylinders 12 is in opposite directions, and the water flowing out of the two sets of main water outlets 6 is in opposite directions. When the automatic water surface cleaner needs to move forward, the water outlet cylinder 12 on the front side is controlled to stop, and the water flows out from the main water outlet cylinder 12 on the rear side, and then from the main water outlet 6 on the rear side of the protective cover 1, pushing the automatic water surface cleaner forward. When the automatic water surface cleaner needs to move backward, the water outlet cylinder 12 on the rear side is controlled to stop, and the water flows out from the main water outlet cylinder 12 on the front side, and then from the main water outlet 6 on the front side of the protective cover 1, pushing the automatic water surface cleaner backward.

[0043] Please refer to the attached diagram in the instruction manual. Figure 2 The inner wall of the front main water outlet cylinder 12 is aligned with the inner wall of the front main water outlet 6, and the inner wall of the rear main water outlet cylinder 12 is aligned with the inner wall of the rear main water outlet 6. This facilitates the smooth flow of water from the main water outlet cylinder 12 through the main water outlet 6. The outer wall of the front main water outlet cylinder 12 abuts against the inner wall of the protective cover 1, and the outer wall of the rear main water outlet cylinder 12 abuts against the inner wall of the protective cover 1. This prevents the main water outlet cylinder 12 from shaking, enhances its stability, and further ensures the accuracy of the water flow direction from the main water outlet cylinder 12 of the automatic water surface cleaner, thus enabling the automatic water surface cleaner to move accurately on the water surface.

[0044] Please refer to the attached diagram in the instruction manual. Figure 2 , Figure 3 and Figure 4 The pumping device also includes auxiliary water outlet cylinders 16, which are located on the left and right sides of the pumping shell 8. Both sets of auxiliary water outlet cylinders 16 are connected to the drainage chamber 11. Auxiliary drainage outlets 9 are provided on both the left and right sides of the protective cover 1. The pump delivers water to the drainage chamber 11. Part of the delivered water flows out from the main water outlet cylinder 12, and another part flows out from the auxiliary water outlet cylinders 16. The water flowing out from the auxiliary water outlet cylinders 16 finally flows out from the auxiliary drainage outlets 9. An auxiliary drainage outlet 10 is provided at the bottom of the protective cover 1. Water flowing from the auxiliary water outlet cylinders 16 can also flow out from the auxiliary drainage outlets 10, accelerating the discharge speed of the water from the auxiliary water outlet cylinders 16 and further increasing the flow rate of the automatic water surface cleaning machine.

[0045] Please refer to the attached diagram in the instruction manual. Figure 2The water pump includes two sets of motors 13, the body of which is installed inside the sealed chamber 7. A drive shaft 14 is connected to the top of each motor 13, and an impeller 15 is installed at one end of each drive shaft 14 that extends into the pump casing 8. When the motor 13 is working, it drives the impeller 15 to rotate via the drive shaft 14, using the centrifugal force generated by the rotation of the impeller 15 to transport water.

[0046] Working principle: When in use, place the cleaning machine on the water surface, then turn on the motor 13. The motor 13 drives the impeller 15 to rotate through the transmission shaft 14. The centrifugal force generated by the rotation of the impeller 15 is used to transport water. The water passes through the filter screen 202, the opening 5, the drain chamber 11, the main water outlet 12 and the main water outlet 6 in sequence. The water flowing out from the main water outlet 6 propels the automatic water surface cleaning machine to move on the water surface.

[0047] Since the sealed chamber 7 and the water pumping device are located inside the protective cover 1, when the automatic water surface cleaning machine collides with the wall or other objects in the water, the protective cover 1 can prevent the sealed chamber 7 and the water pumping device from being deformed by the impact, thereby preventing the main water outlet tube 12 from being deformed, thus ensuring the accuracy of the water flow direction from the main water outlet tube 12, and further enabling the automatic water surface cleaning machine to move accurately on the water surface in the expected direction.

[0048] When the main outlet 6 is not discharging water, the one-way valve 3 covers the main outlet 6. When water flows out of the main outlet 6, the one-way valve 3 is opened by the water flow from the main outlet 6, ensuring the accuracy of the forward and backward directions of the automatic water surface cleaning machine. At the same time, the valve frame 4 blocks the one-way valve 3, preventing the one-way valve 3 from tilting, thus ensuring the covering effect of the one-way valve 3 on the main outlet 6, further ensuring the accuracy of the forward and backward directions of the automatic water surface cleaning machine.

[0049] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
