[0037] The floating debris cleaning equipment (hereinafter referred to as the cleaning equipment) cleans the floating debris on the water surface to achieve the cleaning effect, wherein the cleaning equipment includes a driving component, a shell and a cleaning component, the cleaning component and the driving component are both installed in the shell, and the driving component provides a power source for the cleaning equipment so that the cleaning equipment can move on the water surface. The driving component includes a driving motor and a paddle wheel, the paddle wheel is connected to the output end of the driving motor, and the driving motor drives the paddle wheel to rotate. When the paddle wheel contacts the water and rotates, it can generate thrust, thereby pushing the cleaning equipment to move on the water surface.

[0038] The driving components used in existing cleaning equipment have weak power when in use. The power of the driving components is usually enhanced by increasing the structure of the driving components, such as increasing the size and power of the driving motor and increasing the structure of the paddle wheel. However, increasing the power by increasing the structure of the driving components will cause the structure of the entire cleaning equipment to become larger in order to support the larger driving component. This operation is very inconvenient and will increase the production cost of the cleaning equipment.

[0039] The utility model provides a paddle wheel for driving a motor, which can solve the problem of increasing the power of a driving component while reducing the production cost of a cleaning device.

[0040] See also Figure 1 , Figure 6 In one embodiment of the utility model, the paddle wheel comprises:

[0041] The mounting seat 100 has a mounting area 110, and the mounting area 110 is used for connecting the output end of the driving motor 610; specifically, the output end of the driving motor 610 can directly cooperate with the mounting area 110 to drive the mounting seat 100 to rotate by a direct connection; it can also cooperate with the mounting area 110 through a coupling to achieve an indirect connection so that the driving motor 610 drives the mounting seat 100 to rotate.

[0042] The blade 200 is fixedly arranged on the outside of the mounting seat 100 and extends in the axial direction of the driving motor 610. By extending the blade 200, the area of ​​the blade 200 is increased. When the paddle wheel rotates in the water, the draft area of ​​the paddle wheel will be larger due to the increase in the area of ​​the blade 200. The thrust generated by the corresponding paddle wheel when rotating will also increase accordingly, thereby increasing the power of the driving component. Moreover, the blade 200 is extended in the axial direction of the driving motor 610 to increase the area of ​​the blade 200. Compared with the blade 200 extending in the radial direction of the driving motor 610 to increase the area of ​​the blade 200, the radial length of the paddle wheel can be smaller and the space occupied by the installation can be smaller. At the same time, when the paddle wheel is in use, it can avoid the situation that the driving motor 610 cannot drive the paddle wheel to rotate due to the increase in its own radial length.

[0043] The avoidance portion 300 is provided on the blade 200 to avoid the drive motor 610, so as to avoid the blade 200 from interfering with the drive motor 610 during the rotation of the paddle wheel; when the drive motor 610 drives the mounting seat 100 to rotate, the avoidance portion 300 allows a part of the blade 200 to rotate around the drive motor 610, so that the avoidance portion 300 can be opened at the position where the blade 200 is close to the drive motor 610, that is, the area of ​​the position where the blade 200 is far away from the drive motor 610 will not change, thereby ensuring that the position where the blade 200 is far away from the drive motor 610 is in contact with the water. When the paddle wheel touches the driving motor 610, its draft area is not reduced, thereby increasing the thrust; at the same time, the thrust that the blade 200 can generate in the water at a position away from the driving motor 610 is greater than the thrust that the blade 200 can generate in the water at a position close to the driving motor 610. Since the area of ​​the blade 200 away from the driving motor 610 does not change, the thrust generated by the paddle wheel is greater; and under the action of the avoidance portion 300, the assembly between the blade 200 and the driving motor 610 can be made more compact, making the structure of the driving component smaller, thereby preventing the structure of the driving component from becoming larger while increasing the power, thereby avoiding an increase in production costs.

[0044] The technical solution of the utility model increases the area of ​​the blade 200 by extending the blade 200 toward the driving motor 610, thereby increasing the draft area of ​​the paddle wheel when in use, thereby increasing the thrust of the paddle wheel, and achieving the effect of increasing the power of the driving component; at the same time, an avoidance portion 300 is provided on the blade 200, and the avoidance portion 300 can make the driving motor 610 drive the blade 200 to rotate a part of the blade 200 around the driving motor 610 when the blade 200 is driven to rotate. At the same time, the thrust that can be generated in the water by the position of the blade 200 away from the driving motor 610 is greater than the thrust that can be generated in the water by the position of the blade 200 close to the driving motor 610. Since the area of ​​the position of the blade 200 away from the driving motor 610 does not change, the thrust generated by the paddle wheel is larger; and under the action of the avoidance portion 300, the assembly between the blade 200 and the driving motor 610 can be made more compact, so that the structure of the driving component is smaller, and thus the driving component can avoid its structure becoming larger while improving the power, thereby avoiding an increase in production costs.

[0045] In one embodiment, reference Figure 1 The number of the blades 200 is multiple, and the multiple blades 200 are evenly distributed around the mounting seat 100, wherein the number of the blades 200 can be two, three, four, etc. By arranging multiple blades 200, when the paddle wheel is rotating, the frequency of contact between the blades 200 and the water can be increased, so that the efficiency of the paddle wheel is higher. In this embodiment, the number of the blades 200 is preferably six.

[0046] In one embodiment, reference Figure 1 The paddle wheel further comprises a plurality of connecting plates 400, wherein the connecting plates 400 connect the two blades 200. In the present embodiment, the connecting plates 400 are arranged at the ends of the blades 200, so that the strength of the blades 200 can be improved. When the blades 200 extend along the axial direction of the driving motor 610, the axial length of the blades 200 increases. At this time, the stability of the blades 200 decreases during the rotation of the paddle wheel. The two blades 200 are connected by the connecting plates 400, so that the stability between the blades 200 can be improved, thereby making the blades 200 more stable when the paddle wheel rotates and avoiding the occurrence of breakage. In the present embodiment, the plurality of connecting plates 400 can be arranged at one end of the blade 200, or at both ends of the blade 200. When the connecting plates 400 are arranged at one end of the blade 200, the connecting plates 400 can be arranged at the end of the blade 200 close to the driving motor 610, or at the end of the blade 200 far from the driving motor 610, and no limitation is made here.

[0047] In one embodiment, reference Figure 1, a plurality of the connecting plates 400 form an annular structure. That is to say, the connecting plate 400 is an arc-shaped plate. At this time, during the rotation of the paddle wheel, compared with the rectangular structure, the annular structure generates a smaller acting force on the water. At the same time, it can make the acting force of the water on the annular structure smaller during the rotation of the paddle wheel, reduce the resistance on the output end of the driving motor 610 during rotation, and reduce the energy loss of the driving motor 610.

[0048] In one embodiment, referring to Figure 2 , the paddle wheel further includes a reinforcing plate 500, and the reinforcing plate 500 connects the annular structure and the mounting seat 100. Wherein the number of the reinforcing plates 500 is multiple. The reinforcing plate 500 is to improve the strength of the annular structure, improve the connection stability between the annular structure and the mounting seat 100, and further improve the connection stability between the blade 200 and the mounting seat 100, so as to achieve the purpose of improving the strength of the paddle wheel. At the same time, in this embodiment, both the reinforcing plate 500 and the annular structure are arranged away from the driving motor 610, so as to avoid the reinforcing plate 500 affecting the installation of the driving motor 610 and avoid the problem of loose installation between the driving motor 610 and the paddle wheel.

[0049] In one embodiment, referring to Figure 1 , the blade 200 has a propulsion section 210 and a turning section 220. The propulsion section 210 is arranged close to the driving motor 610, and the propulsion section 210 and the turning section 220 are arranged at an angular relationship. In this way, the area of the blade 200 can be increased, compared with the blade 200 with a planar structure. By increasing the area of the blade 200, the contact area between the blade 200 and the water can be increased, and the contact area between the paddle wheel and the water during rotation can be increased, so that the thrust generated by the paddle wheel is also increased.

[0050] In this embodiment, referring to Figure 3 , there is a preset angle a between the propulsion section 210 and the axis of the driving motor 610, 0° < a < 45°. Preferably, the preset angle between the propulsion section 210 and the axis of the driving motor 610 is 15°. In this way, while ensuring that the area of the propulsion section 210 is large enough, it can ensure that the force of the water acting on the propulsion section 210 is not divided out too much, so that the thrust of the paddle wheel can be ensured. When a > 45°, the force of the water acting on the propulsion section 210 is less, resulting in a decrease in the thrust of the paddle wheel. The divided force is mainly the force divided along the axial direction of the driving motor 610.

[0051] In this embodiment, referring to Figure 3, there is a preset angle b between the steering section and the axis of the drive motor 610, 0° < b < 45°, and the angle between the steering section and the axis of the drive motor 610 is preferably 30°. Such a setting can make more of the force exerted by the water on the steering section be distributed in the axial direction of the drive motor 610. At this time, when the cleaning device 600 is turning, it can turn quickly, and at the same time, the rotation angle can be reduced, enabling the cleaning device 600 to complete the turn in a smaller space, improving the use effect; and at an angle of 30°, the radial force exerted by the water on the steering section can be ensured, thereby ensuring the thrust of the steering section.

[0052] In one embodiment, referring to Figure 4 , there is a preset angle c between the blade 200 and the axis of the drive motor 610, 0° < c < 45°, and the angle between the blade 200 and the axis of the drive motor 610 is preferably 15°. In this way, while ensuring that the area of the propulsion section 210 is large enough, it can be ensured that the force exerted by the water on the propulsion section 210 is not distributed too much, so that the thrust of the paddle wheel can be ensured.

[0053] The present utility model also proposes a cleaning device 600, referring to Figure 5 、 Figure 6 , the cleaning device 600 includes a drive motor 610 and a paddle wheel. The specific structure of the paddle wheel refers to the above-mentioned embodiment. Since the cleaning device 600 adopts all the technical solutions of the above-mentioned all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated one by one here. Among them, the paddle wheel is the paddle wheel as described in any of the above embodiments.

[0054] In one embodiment, referring to Figure 6 , the cleaning device 600 has two sets of drive motors 610 and paddle wheels. When the cleaning device 600 needs to turn, only one of the paddle wheels needs to be driven to rotate. At the same time, under the action of the steering section 220 in the paddle wheel, the cleaning device 600 can turn quickly, and at the same time, the rotation angle can be reduced, enabling the cleaning device 600 to complete the turn in a smaller space, improving the use effect. At the same time, under the action of the above-mentioned drive motor 610 and paddle wheel, the cleaning device 600 can be made lightweight and compact, facilitating the cleaning of small areas of water surfaces, such as ponds, swimming pools, etc.

[0055] The above is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present utility model.
