Description

Technical Field

[0001] The utility model relates to a rowing blade deformation mechanism, and more specifically, to a rowing blade deformation mechanism which can be transformed between a rowing shape and a wheel shape. Background Art

[0002] Amphibious devices are used in many fields. For example, in the process of cleaning floating pollutants on the water surface such as fallen leaves, plastic bottles, and floating plastic bags, it is necessary to set up a device that can float and move on the water surface. This requires the use of a paddling propeller, such as a paddling blade. Under the rotation of the paddling blade, the floating object cleaning device is driven to move on the water surface to achieve the cleaning of floating pollutants on the water surface.

[0003] However, the existing floating object cleaning device on the water surface only has the function of moving on the water surface, but does not have the function of moving on land, which brings many inconveniences to the floating object cleaning device on the water surface. This is because when the surface pollutants are cleaned up or are fully loaded, the floating pollutants collected by the cleaning device need to be unloaded and then put back into the water surface for re-cleaning operations.

[0004] If the surface floating debris cleaning device can move on land, this problem will be solved. When the cleaning is completed or fully loaded, the cleaning device can go ashore by itself and move on land to transport the collected pollutants to the destination for unloading, which will increase its work efficiency and reduce labor.

Four blades that can be opened and closed are evenly arranged on the cylindrical impeller. The blades are in the shape of a 1 / 4 arc. A wheel axle is arranged in the center of the cylindrical impeller. The cylindrical impeller is rotatably arranged on the U-shaped rod via the wheel axle. The driving motor is fixed on the U-shaped rod, and the output of the driving motor is connected to the wheel axle through transmission. It is characterized in that it also includes a U-shaped plate, a steering gear, a connecting rod and a transmission mechanism.

DETAILED DESCRIPTION

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figures 1 to 7As shown, the front view, rear view, left view, right view, top view, bottom view and stereoscopic view of the paddling blade deformation mechanism of the utility model are respectively given. The paddling blade deformation mechanism shown is composed of a servo 1, a drive motor 2, a cylindrical impeller 3, a U-shaped plate 4, a U-shaped rod 5 and a connecting rod 6. The drive motor 2 is fixed on the U-shaped rod 5. Four blades 7 are evenly arranged on the periphery of the cylindrical impeller 3. Each blade 7 is in the shape of a 1 / 4 arc. A rotating shaft 22 is arranged in the center of the cylindrical impeller 3. Both ends of the rotating shaft 22 are rotatably arranged on the U-shaped rod 5, and the output of the drive motor 2 is connected to the rotating shaft 22. When the driving motor 2 drives the rotating shaft 22 and the cylindrical impeller 3 to rotate synchronously (assuming it is forward rotation), the blades 7 on the cylindrical impeller 3 are opened under the action of centrifugal force. At this time, the cylindrical impeller 3 is used as a paddle blade; when the driving motor 2 drives the rotating shaft to rotate in the opposite direction (this is negative rotation), the blades 7 on the cylindrical impeller 3 are in a closed state, and the cylindrical impeller 3 can be used as a wheel.

[0027] The steering gear 1 is fixed on the U-shaped plate 4, the connecting rod 6 is rotatably fixed on the U-shaped plate 4 via the bearing 14 fixed on the U-shaped plate 4, the outer end of the connecting rod 6 is fixedly connected to the U-shaped rod 5, and the output shaft of the steering gear 1 is transmission-connected to the inner end of the connecting rod 6 via the transmission mechanism 8. In this way, the steering gear 1 drives the U-shaped rod 5 and the cylindrical impeller 3 to rotate synchronously by 90° through the transmission mechanism 8 and the connecting rod 6. When the blades 7 on the cylindrical impeller 3 are driven to be in a state perpendicular to the horizontal plane, the blades 7 on the cylindrical impeller 3 are in a spiral blade state. At this time, the cylindrical impeller 3 can be used in a water surface floating object cleaning device to row. The steering gear 1 drives the cylindrical impeller 3 to rotate 90°, so that the cylindrical impeller 3 rotates to a position where the blades 7 are parallel to the horizontal plane. At this time, the cylindrical impeller 3 can be used as a wheel. After being applied to the water surface floating object cleaning device, it can have a land walking function.

[0028] The U-shaped plate 4 shown is composed of a vertical plate 12 and two horizontal plates 13 fixed on the vertical plate 12, the driving motor 2 is fixed on the inner surface of the horizontal plate 13, the bearing 14 is fixed on the vertical plate 12, and the connecting rod 6 is fixed on the bearing 14. The transmission mechanism 8 is composed of a driving sprocket 9, a driven sprocket 10 and a chain 11. The driving sprocket 9 is fixed on the output shaft of the steering gear 1, and the driven sprocket 10 is fixed on the inner end of the connecting rod 6. The driving sprocket 9 is connected to the driven sprocket 10 through the chain 11. In this way, the steering gear 1 can drive the connecting rod 6 to rotate through the transmission mechanism 8.

[0029] The U-shaped rod 5 shown is composed of a vertical rod 15, an upper crossbar 16 and a lower crossbar 17. The upper crossbar 16 and the lower crossbar 17 are fixed to the two ends of the vertical rod 15 in parallel with each other, and the outer end of the connecting rod 6 is fixed to the middle of the vertical rod 15, so that the U-shaped rod 5 can be driven to rotate during the rotation of the connecting rod 6. The driving motor 2 shown is fixed to the upper crossbar 16, and a reducer 18 is arranged on the output shaft of the driving motor 2. The output shaft of the reducer 18 is connected to the wheel shaft 21 on the cylindrical impeller 3 through a coupling 19. In this way, the driving motor 2 can drive the cylindrical impeller 3 to rotate in different directions through the reducer 18 and the coupling 19, so that the cylindrical impeller 3 can be used as a spiral rotating blade or wheel.

[0030] The cylindrical impeller 3 shown is composed of two circular rings 20, a wheel shaft 21 and four blades 7. The two circular rings 20 are arranged parallel to each other, and the wheel shaft 21 is located at the center inside the two circular rings 20. The wheel shaft 21 is fixedly connected to each circular ring 20 through four wheel spokes 27 to form a stable cylindrical impeller 3. The four blades 7 are all in the shape of a quarter circle arc. The blades 7 are fixed on the rotating shaft 22. The two ends of the rotating shaft 22 are rotatably arranged on the two circular rings 20. The rotating shaft 22 on the blades 7 rotates to realize the opening and closing of the blades 7.

[0031] When the blade 7 is in the open state, it should be opened at a certain angle so that it can be used as a paddle. Figure 8 and Fig. 9 As shown, schematic diagrams of the matching structure of the rotating shaft and the circular ring in the utility model are given. The two circular rings 20 are provided with rotating shaft holes for inserting the rotating shaft 22. A limiting block 23 is arranged at the bottom of the rotating shaft hole. The cross section of the limiting block 23 is in the shape of a right triangle. The end of the rotating shaft 22 is a semicircular portion 24, that is, the end of the rotating shaft 22 is semicircular. In this way, the limiting block 23 limits the position of the rotating shaft 22, so that the blade 7 can only rotate 45° from the closed state, and is in the open state after rotating 45°.

[0032] like Fig.10 As shown, a schematic diagram of the paddling blade deformation mechanism of the utility model in the paddling state is given. The wavy line in the figure is the liquid level 25. At this time, the steering gear 1 drives the cylindrical impeller 3 to rotate to the position where the blade 7 is perpendicular to the horizontal plane, and at this time, the upper crossbar 16 where the drive motor 2 is located is located above the lower crossbar 17. Looking from the side where the drive motor 2 is set to the direction of the lower crossbar 17, the drive motor 2 drives the cylindrical impeller 3 to rotate clockwise. Under the action of centrifugal force, the blade 7 is in an open state. The blade 7 in the open state can paddle water and generate a force for forward movement. When in use, in order to maintain the balance of the traction force generated by paddling water, two paddling blade deformation mechanisms of the utility model are set and used at the same time.

[0033] like Fig.11As shown, a schematic diagram of the paddling blade deformation mechanism of the utility model is given in a wheel state. At this time, the servo 1 drives the cylindrical impeller 3 to flip 90°, so that the cylindrical impeller 3 rotates to a position where the blade 7 is parallel to the horizontal plane. Looking from the side where the drive motor 2 is set in the direction of the lower cross bar 17, the drive motor 2 drives the cylindrical impeller 3 to rotate counterclockwise. At this time, the blade 7 on the cylindrical impeller 3 is closed, and the drive motor 2 drives the cylindrical impeller 3 to rotate counterclockwise to be used as a wheel, and can drive the corresponding device to move on land.
