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 that takes into account both water flow rate and walking speed. Background Technology

[0002] Due to various reasons, modern urban and rural waterways are littered with various types of litter thrown into them by residents; various aquatic plants, branches, and garbage flowing into the waterways with mountain torrents during summer rainstorms; and the explosive growth of aquatic plants caused by eutrophication. As a result, a large amount of aquatic plant garbage floats on the surface of urban and rural waterways. Surface garbage is an important factor affecting the cleanliness of water bodies, and regularly cleaning up surface garbage is an important and arduous task.

[0003] Currently, there are two methods for cleaning up marine debris. One is manual dredging, which is labor-intensive, inefficient, and time-consuming, often consuming a lot of manpower and resources with little effect, resulting in a significant waste of human and material resources. The other method is to use automatic water surface cleaning machines, which save manpower and improve cleaning efficiency.

[0004] However, there are currently three types of automatic water surface cleaning machines, each with its own drawbacks. The first type, while only having a water pumping device and low cost, cannot clean while moving. The second type, while only having a propulsion device and low cost, cannot clean while stationary. The third type requires both a water pumping device and a propulsion device to achieve both stationary and moving cleaning capabilities, which increases the cost of having two sets of devices.

[0005] There is currently no automatic water surface cleaning machine that can clean while stationary and while moving, while also solving the problem of high cost of two separate devices.

[0006] To achieve both stationary and mobile cleaning capabilities, while also addressing the high cost of separate systems, we have recently developed a multi-functional automatic water surface cleaning machine. When using this machine to collect debris from the water surface, it is first placed in the water. The buoyancy generated by the flotation device causes the filter screen and filter cylinder to float on the water. Activating the pump draws water into the filter screen, which then flows through the mesh and out of the filter cylinder, finally exiting through the main outlet. This allows for both stationary and mobile cleaning, reducing costs.

[0007] However, our newly developed automatic water surface cleaner, which can clean both stationary and mobile locations, requires a specific flow rate at the main outlet to ensure that all debris around the filter cartridge is properly collected. If the flow rate is too high, the cleaner will move too fast, and the debris won't be fully collected before the machine moves on, reducing its cleaning efficiency. Maintaining a specific flow rate results in a smaller volume of water filtered per unit time, leading to less debris being filtered and lower overall cleaning efficiency. This makes it difficult to balance water flow and movement speed. Utility Model Content

[0008] To address the issue of our newly developed multi-functional automatic water surface cleaning machine, which can clean both stationary and mobile surfaces, namely the inability to balance water flow rate and walking speed, this invention provides an automatic water surface cleaning machine that balances both water flow rate and walking speed.

[0009] This utility model provides an automatic water surface cleaning machine that balances water flow rate and walking speed, and adopts the following technical solution:

[0010] An automatic water surface cleaning machine that balances water flow rate and walking speed includes a sealed chamber and a water pumping device. A filter device is installed on the top of the water pumping device. The water pumping device includes a water pumping shell and a water pump. The water pumping shell is installed at the bottom of the filter device, and the water pumping shell and the filter device form a water pumping chamber. An opening is provided at the bottom of the filter device, and the opening communicates with the water pumping chamber. Main water outlet cylinders are provided on both the front and rear sides of the water pumping shell, and the main water outlet cylinders communicate with the water pumping chamber. Auxiliary water outlet cylinders are connected to both the left and right sides of the water pumping shell, and the auxiliary water outlet cylinders communicate with the water pumping chamber.

[0011] By adopting the above technical solution, under the action of the water pump, water passes through the filter device, opening, pumping chamber, main outlet cylinder and auxiliary outlet cylinder in sequence. The water flow from the main outlet cylinder propels the cleaning machine to move on the water surface, while the water flow from the auxiliary outlet cylinder increases the flow rate of the cleaning machine, thereby increasing the volume of water filtered by the filter device per unit time, thus increasing the amount of garbage filtered per unit time. This allows the cleaning machine to balance water flow rate and moving speed.

[0012] 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.

[0013] By adopting the above technical solution, the garbage on the water surface will be carried into the filter screen and collected inside the filter screen, making it convenient to collect the garbage.

[0014] Optionally, several floating devices are connected to the outside of the filter cylinder.

[0015] By adopting the above technical solution, the automatic water surface cleaning machine can float on the water surface.

[0016] Optionally, the flow rates of the water flowing out of the two sets of auxiliary water outlets are equal.

[0017] By adopting the above technical solution, the water flow from the two sets of auxiliary water outlets has equal reaction forces on the left and right sides of the automatic water surface cleaning machine, which helps the automatic water surface cleaning machine to move stably on the water surface.

[0018] Optionally, the axes of the two sets of main water outlet cylinders are parallel to each other, and when the automatic water surface cleaning machine is placed in the water, the axes of the two sets of main water outlet cylinders are parallel to the horizontal plane.

[0019] By adopting the above technical solution, the main water outlet tube can concentrate the water flow and prevent the water flow from being too dispersed, thus affecting its ability to propel the automatic cleaning machine.

[0020] Optionally, the auxiliary water outlet cylinder is L-shaped, and includes a horizontal section and a vertical section connected to each other. The horizontal section is connected to the pumping shell, and the horizontal section and the vertical section are perpendicular to each other.

[0021] By adopting the above technical solution, when the automatic water surface cleaning machine is placed in the water, the water entering the auxiliary water outlet tube first flows through the horizontal section and then through the vertical section. The direction of the water flowing out from the vertical section is vertically downward, thereby reducing the component force of the water flowing out of the auxiliary water outlet tube on the automatic water surface cleaning machine on the horizontal plane and reducing the interference with the direction of movement of the automatic water surface cleaning machine.

[0022] Optionally, the side of the pump casing away from the opening abuts against the upper wall of the sealed chamber.

[0023] By adopting the above technical solution, the filter cartridge, the pumping shell, and the upper wall of the sealed chamber are surrounded by a closed pumping cavity.

[0024] 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.

[0025] By adopting the above technical solution, when the motor is working, it drives the impeller to rotate through the transmission shaft. The impeller drives the water to move, so that the water in the filter cartridge flows into the pumping chamber through the opening, and the water entering the pumping chamber is discharged through the main outlet pipe and the auxiliary outlet pipe.

[0026] Optionally, a partition is installed in the middle of the water pumping shell, and two sets of motors are located on both sides of the partition.

[0027] By adopting the above technical solution, when the automatic water surface cleaning machine needs to move forward, the rear water pump operates while the front water pump stops operating, and water flows out from the rear main water outlet. Because of the baffle, water will not flow out from the front main water outlet, which is more conducive to pushing the automatic water surface cleaning machine forward. When the automatic water surface cleaning machine needs to move backward, the front water pump operates while the rear water pump stops operating, and water flows out from the front main water outlet. Because of the baffle, water will not flow out from the rear main water outlet, which is more conducive to pushing the automatic water surface cleaning machine backward.

[0028] Optionally, the water flowing out of the two sets of main outlet cylinders flows in opposite directions.

[0029] By adopting the above technical solution, the automatic pool cleaning machine has the functions of moving forward and backward.

[0030] In summary, this utility model has at least one of the following beneficial effects:

[0031] Under the action of the water pump, water passes through the filter device, opening, pumping chamber, main outlet pipe and auxiliary outlet pipe in sequence. The water flow from the main outlet pipe propels the cleaning machine to move on the water surface, while the water flow from the auxiliary outlet pipe increases the flow rate of the cleaning machine, thereby increasing the volume of water filtered by the filter device per unit time, thus increasing the amount of garbage filtered per unit time. This allows the cleaning machine to balance water flow rate and moving speed.

[0032] By setting up two sets of main water outlets with opposite water flow directions, the automatic pool cleaner has forward and reverse functions. When it needs to move forward, the pump runs, opening the rear main water outlet and closing the front main water outlet, allowing water to flow from the rear main water outlet and propelling the cleaner forward. When the cleaner needs to move backward, the pump runs, opening the front main water outlet and closing the rear main water outlet, allowing water to flow from the front main water outlet and propelling the automatic pool cleaner backward.

[0039] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0040] 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 that balances water flow rate and walking speed. It includes a sealed chamber 3 and a pumping device 4. A filter device 2 is installed on the top of the pumping device 4. The pumping device 4 includes a pumping shell 401 and a pump. The filter device 2 includes a filter cylinder 201, which is installed on top of the pumping shell 401. A filter screen 202 is installed inside the filter cylinder 201. Debris on the water surface is drawn into the filter screen 202 and collected therein, facilitating waste collection. Several floating devices 1 are fixedly connected to the outside of the filter cylinder 201, allowing the automatic water surface cleaning machine to float on the water surface.

[0041] Please refer to the attached diagram in the instruction manual. Figure 2 , Figure 3 and Figure 4 The water-drawing shell 401 is installed at the bottom of the filter device 2, forming a water-drawing chamber 402 between the water-drawing shell 401 and the filter device 2. An opening 7 is provided at the bottom of the filter device 2, communicating with the water-drawing chamber 402. Main water outlet cylinders 5 are provided on both the front and rear sides of the water-drawing shell 401, and these main water outlet cylinders 5 are also communicating with the water-drawing chamber 402. The axes of the two sets of main water outlet cylinders 5 are parallel to each other. When the automatic water surface cleaner is placed in the water, the axes of both sets of main water outlet cylinders 5 are parallel to the horizontal plane. The main water outlet cylinders 5 concentrate the water flow, preventing it from becoming too dispersed and thus hindering the movement of the automatic cleaner. The side of the water-drawing shell 401 away from the opening 7 rests against the upper wall of the sealed chamber 3. This creates a closed water-drawing chamber 402, formed by the filter cylinder 201, the water-drawing shell 401, and the upper wall of the sealed chamber 3. The water flows out of the two sets of main water outlet cylinders 5 in opposite directions, giving the automatic pool cleaner forward and backward movement capabilities.

[0042] Please refer to Figure 3 in the attached diagram of the instruction manual. Figure 4 Auxiliary water outlet cylinders 6 are connected to both sides of the water pumping shell 401, and the auxiliary water outlet cylinders 6 are connected to the water pumping chamber 402. The water flow from the two sets of auxiliary water outlet cylinders 6 is equal. The reaction force of the water flow from the two sets of auxiliary water outlet cylinders 6 on the left and right sides of the automatic water surface cleaning machine is equal, which helps the automatic water surface cleaning machine to move stably on the water surface.

[0043] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 3 and Figure 4 The auxiliary water outlet cylinder 6 is L-shaped and includes interconnected horizontal and vertical sections. The horizontal section is connected to the water suction shell 401, and the horizontal and vertical sections are perpendicular to each other. When the automatic water surface cleaner is placed in the water, the water entering the auxiliary water outlet cylinder 6 first flows through the horizontal section, then through the vertical section, and the water flowing out of the vertical section flows vertically downwards. This reduces the component force exerted by the water flowing out of the auxiliary water outlet cylinder 6 on the automatic water surface cleaner on the horizontal plane, thus reducing interference with the direction of movement of the automatic water surface cleaner.

[0044] Please refer to the attached diagram in the instruction manual. Figure 2 and Figure 3 The water pump includes two sets of motors 4031. The bodies of both sets of motors 4031 are installed inside the sealed chamber 3. The top of each set of motors 4031 is connected to a drive shaft 4032. An impeller 4033 is installed at one end of each drive shaft 4032 that extends into the pumping shell 401. When the motors 4031 are working, they drive the impellers 4033 to rotate through the drive shafts 4032. The impellers 4033 drive the water to move, so that the water in the filter cartridge 201 flows into the pumping chamber 402 through the opening 7, and the water entering the pumping chamber 402 is discharged through the main outlet pipe 5 and the auxiliary outlet pipe 6.

[0045] Working Principle: In use, the automatic water surface cleaner is placed at the desired water surface location. The floating device 1 allows the cleaner to float on the water. Then, the pump is turned on, and water enters the filter cylinder 201 and flows from the opening 7 into the pumping chamber 402. Debris on the water surface is carried into the filter screen 202 and collected there for easy collection. When the motor 4031 is working, it drives the impeller 4033 to rotate via the drive shaft 4032. The rotation of the impeller 4033 moves the water, thus drawing water from the pumping chamber 402 out through the main outlet cylinder 5 and the auxiliary outlet cylinder 6. The water flowing from the main outlet cylinder 5 propels the water surface cleaner across the water surface, while the water flowing from the auxiliary outlet cylinder 6 increases the flow rate of the automatic water surface cleaner, increasing the volume of water filtered per unit time by the filter device 2. Therefore, the amount of debris filtered per unit time also increases, allowing the cleaner to balance water flow rate and travel speed.

[0046] Because it has two sets of main water outlet cylinders 5, and the water flows out of the two sets of main water outlet cylinders 5 in opposite directions, the automatic pool cleaning machine has forward and backward functions. When the automatic water surface cleaning machine needs to move forward, the rear pump runs and the front pump stops running. Water flows out from the rear main water outlet cylinder 5. Because of the baffle 8, water will not flow out from the front main water outlet cylinder 5, which is more conducive to pushing the automatic water surface cleaning machine forward. When the automatic water surface cleaning machine needs to move backward, the front pump runs and the rear pump stops running. Water flows out from the front main water outlet cylinder 5. Because of the baffle 8, water will not flow out from the rear main water outlet cylinder 5, which is more conducive to pushing the automatic water surface cleaning machine backward.

[0047] 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 included within the scope of protection of this utility model.
