Description

Technical Field

[0001] This utility model relates to a flotation device, and more specifically, to a multifunctional flotation device that can move in silt and water. Background Technology

[0002] With the rapid development of river transportation and the increasing emphasis on river ecological protection in my country, river dredging and clearing operations are becoming more frequent. During river dredging, a dam is first constructed at the dredging section. Then, water pumps are used to pump the deeper water from the river to the outside of the dam. Due to the silt in the riverbed, personnel cannot normally enter the river directly, otherwise they would become trapped. This makes it difficult to rationally select pumping points based on actual conditions. Therefore, to select pumping points according to actual conditions, it is necessary to design a device that can move in both silt and water—an "amphibious" device—to move the pumping point to the required location.

[0003] Currently, devices capable of moving freely in water are quite common, such as small electric boats, which can move in water under the control of the operator. However, they cannot move in silt, thus failing to meet the requirements for movement in rivers awaiting dredging. Therefore, a new device needs to be designed to adapt to movement in both silt and water. Hence, this utility model proposes a multifunctional floating device. Summary of the Invention

[0004] In order to overcome the shortcomings of the above-mentioned technical problems, this utility model provides a multifunctional floatation device.

[0005] This utility model discloses a multifunctional floatation device, comprising a shell, a traveling mechanism, and a steering mechanism. Hollow mud pushers are fixed to both sides of the shell, with a conical tip at the front and a cylindrical rear end. The shell contains a device cavity and a pumping cavity from bottom to top. The traveling mechanism consists of a traveling motor, a drive shaft, and two water wheels. Both the traveling motor and the drive shaft are located within the device cavity, with both ends of the drive shaft extending out of the shell. The two water wheels are fixed to both ends of the drive shaft. A small gear is fixed to the output shaft of the traveling motor, and a large gear meshing with the small gear is fixed to the drive shaft. The shell has an inlet and an outlet, both connected to the pumping cavity. The device cavity contains a battery and a control board for controlling the travel and steering mechanisms.

[0006] The multifunctional float of this utility model has a steering mechanism consisting of a left steering motor, a right steering motor, a left steering wheel, and a right steering wheel. The left and right steering motors are fixed in the device cavity. The left steering wheel and the right steering wheel are located on the left and right sides of the front end of the shell, respectively. The output ends of the left and right steering motors are connected to the left and right steering wheels, respectively, via a steering shaft passing through the shell.

[0007] The multifunctional float of this utility model has a top cover at the upper end of the shell, which is connected to the shell by connecting bolts. The inside of the top cover is a storage cavity for storing objects, and the upper end of the top cover has an upper opening.

[0008] The multifunctional float of this utility model has a paddle wheel, which is composed of a cylinder and sheet-like blades evenly fixed around the cylinder.

[0009] The multifunctional floater of this utility model has a sealed cavity that is not connected to the outside world, and the water pumping cavity is connected to the outside world only through the inlet and outlet.

[0010] The beneficial effects of this utility model are as follows: The multifunctional floating device of this utility model is equipped with a shell, a traveling mechanism, and a steering mechanism. The traveling mechanism consists of a traveling motor, a drive shaft, and two water wheels. The water pumping chamber of the shell is provided with a water inlet and a water outlet. The water outlet is connected to the water pumping pipe of the water pump. Hollow mud pushers are fixed on both sides of the shell, so that the entire floating device can float well in water or silt. During the process of the traveling motor driving the water wheels to rotate, the entire floating device can be driven to move freely in water or silt. During the movement, the direction of travel is adjusted by the steering mechanism to control the entire floating device to move to the desired position. In this way, fixed-point water pumping operations can be carried out in rivers containing silt without the need for personnel to go into the river. The better water pumping point can be freely selected, which improves the pumping efficiency.

[0011] Furthermore, by setting up a steering mechanism consisting of left and right steering motors and left and right steering wheels, the left and right steering wheels can be driven to rotate alternately or differentially by the left and right steering motors, thereby driving the entire float to turn and adjust the direction of travel of the float.

[0012] Furthermore, by setting a top cover with an internal storage cavity at the upper end of the shell, the items to be transported can be placed into the storage cavity through the top opening of the top cover, thereby realizing the transportation of items in silt or water.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 5 As shown, the front view, rear view, right view, top view, and bottom view of the multifunctional floatation device of this utility model are given respectively. Figure 6 and Figure 7 All of them are given a 3D diagram. Figure 8 and Figure 9 All images provide cross-sectional views, showing that the multifunctional floatation device consists of a shell 1, a traveling mechanism, and a steering mechanism. The shell 1 is partially spherical in shape. The lower part of the shell 1 contains a component cavity 13, a sealed cavity that does not communicate with the outside. Some components of the traveling and steering mechanisms are fixed within the component cavity 13. The upper part of the shell 1 contains a water pumping chamber 14. The shell 1 is equipped with an inlet 8 and an outlet 9 that communicate with the water pumping chamber 14. The water pumping chamber 14 is only connected to the outside through the inlet 8 and the outlet 9.

[0023] Both sides of the shell 1 shown are fixed with pushers 6. The pushers 6 are hollow or made of lightweight materials that can float in water to ensure that the entire floater can float in water or silt without sinking excessively. The front end of the pusher 6 shown is conical and the rear end is cylindrical to reduce the resistance of the floater in water or silt.

[0024] The propulsion mechanism shown consists of a propulsion motor 17, a drive shaft 12, and two paddle wheels 3. The propulsion motor 17 is fixed in the device cavity 13, and the middle part of the drive shaft 12 is located in the device cavity 13. Both ends of the drive shaft 12 pass through the housing 1, and the two paddle wheels 3 are fixed at the two ends of the drive shaft 12 that pass through the housing 1. A small gear 18 is fixed on the output shaft of the propulsion motor 17, and a large gear 19 is fixed on the drive shaft 12, with the large gear 19 meshing with the small gear 18. In this way, the propulsion motor 17 drives the drive shaft 12 and the paddle wheels 3 to rotate. The rotating paddle wheels 3, by pushing the water or silt backward, propel the float forward.

[0025] The steering structure shown consists of a left steering motor 21, a right steering motor 22, a left steering wheel 4, and a right steering wheel 5. The left steering motor 21 and the right steering motor 22 are fixed in the device cavity 13 with their output shafts facing left and right, respectively. The left steering wheel 4 and the right steering wheel 5 are located on the left and right sides of the front end of the housing 1, respectively. The output shafts of the left steering motor 21 and the right steering motor 22 are connected to the left steering wheel 4 and the right steering wheel 5 via the steering shaft 11, respectively. Thus, by driving the left steering wheel 4 and the right steering wheel 5 alternately or differentially with the left steering motor 21 and the right steering motor 22, the float can be steered to control its movement to the desired position.

[0026] The device cavity 13 shown houses a battery 16 and a control board 20. The control board 20 controls the operation of the walking and steering mechanisms, while the battery 16 provides power to the travel motor 17, the left steering motor 21, the right steering motor 22, and the control board 20. A top cover 2 is fixed to the upper end of the housing 1 shown. The interior of the top cover 2 is a storage cavity 15 for storing items to be transported. An upper opening 7 is provided at the upper end of the top cover 2. The top cover 2 is detachably connected to the housing 1 via three connecting screws 10.

[0027] The paddling wheel 3 shown is a paddle wheel, which consists of a cylinder and blades evenly fixed around the cylinder. During use, if the float floats on the water surface and the inlet 8 is not submerged, a hanging inlet pipe needs to be connected to the inlet 8 to ensure that water from the river to be pumped enters.

[0028] In the use of this multifunctional floating device, the inlet pipe of the water pump is first connected to the outlet 9. Then, by operating the travel motor 17, the left steering motor 21, and the right steering motor 22, the floating device moves through the water and silt. Once the floating device reaches the desired pumping position, the water pump is turned on to perform pumping operations at a fixed location in the river. Simultaneously, items can be placed in the storage chamber 15 to transport items through rivers and silt.
