[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] like Figure 1~Figure 4 As shown, the automatic lifting device for planting rice on a floating board of the present invention comprises a floating board 1, three fixed pulleys, and at least one bottom-sinking counterweight block and at least one suspended counterweight block with a small counterweight, wherein the counterweight block is connected to the floating board 1 by a steel cable or a flexible rope, and the fixed pulley is used to adjust the position of the counterweight block and the weight of the counterweight block to achieve automatic floating or sinking of the floating board.

[0020] Specifically, three fixed pulleys are installed at the bottom of the floating board 1 through a steel wire rope 11. The three fixed pulleys are fixed pulley 1 2, fixed pulley 3 8, and fixed pulley 2 3, and are uniformly distributed on the axially symmetrical center line of the floating board 1 in sequence. At least one sinking counterweight block and at least one suspended counterweight block are connected below the fixed pulley 1 2 and the fixed pulley 2 3 through a flexible rope, or a sinking counterweight block and a suspended counterweight block are connected below the fixed pulley 3 8 through a flexible rope to adapt to different water level fluctuation amplitudes; at the same time, the weight of the suspended counterweight block is adjustable to achieve automatic floating or sinking of the floating board 1.

[0021] The weight of the suspended counterweight blocks increases in sequence within the range of 1kg-6kg to achieve rapid response at different water level change speeds, improve the stability and lifting sensitivity of the floating board 1, and achieve optimal stability and cost-effectiveness.

[0022] The floating board is made of lightweight and high-strength materials and can bear counterweights of different weights. A fixed pulley is installed on the floating board, and counterweights of different weights are connected to both sides of the pulley. The floating board can be automatically raised and lowered by adjusting the counterweights. The counterweights are installed at both ends or multiple points of the floating board according to different schemes to control the balance and stability of the floating board.

[0023] According to experimental data, the rise and fall of the floating plate depends on the torque difference of the counterweights on both sides of the pulley. When the water level changes, the buoyancy relationship between the floating plate and the water changes, and the system automatically adjusts its position through the physical action of the counterweights: When the water level drops: the buoyancy decreases, and the floating plate will sink naturally. At this time, the counterweights on both sides of the pulley produce balance through the torque difference and automatically sink slowly. When the water level rises: the buoyancy increases, the floating plate will float up naturally, and the counterweights will react to the pulley system to adjust the floating height of the floating plate to maintain balance.

[0024] In the present invention, the floating board 1 is 1m×0.5m×0.1m in length, width and height and weighs about 1.6kg. Different installation methods of the counterweight block produce different effects, and the motion parameters of the floating board under different weights are tested to match different water level fluctuation amplitude scenarios.

[0025] Embodiment 1 like Figure 1 As shown, fixed pulley 1 2 and fixed pulley 2 3 are connected to the corresponding bottom counterweight block 1 4 and bottom counterweight block 2 5, and the four are connected by flexible ropes, and a suspended counterweight block 1 6 is suspended in the middle of the flexible rope to adapt to the scene with small water level fluctuation; the weight of the bottom counterweight block 1 4 and the bottom counterweight block 2 5 is 10kg, and the weight of the suspended counterweight block 1 6 increases in the range of 2kg-5kg. Among them, the motion parameters of the floating board are shown in Table 1: Table 1 It can be seen from Table 1 that the horizontal horizontal displacement, extreme horizontal displacement, extreme vertical displacement and average vertical displacement change of the floating plate are all small, and the response time is fast. This configuration can maintain good stability and lifting sensitivity when the water level changes. At the same time, the cost and stability are optimal, and it is suitable for scenes with small water level fluctuations.

[0026] Embodiment 2 like Figure 2As shown, fixed pulley 1 2 and fixed pulley 2 3 are connected to the corresponding bottom counterweight block 1 4 and suspended counterweight block 2 7. The weight of the bottom counterweight block 1 4 is 10 kg, and the weight of the suspended counterweight block 2 7 increases in the range of 2 kg-6 kg. The motion parameters of the floating board are shown in Table 2.

[0027] Table 2 It can be seen from Table 2 that the fluctuation of the ultimate vertical displacement and the average vertical displacement of the floating plate is small. This solution is suitable for scenes with large water level fluctuations and responds faster when the water level changes sharply. The light end of this solution will rotate 360° around the heavy end.

[0028] Option 3: If Figure 3 As shown, the fixed pulley 1 2 is connected to the bottom counterweight block 1 4 and the suspended counterweight block 3 9 by a flexible rope, and the fixed pulley 2 3 is connected to the bottom counterweight block 2 5 and another suspended counterweight block 3 9 by a flexible rope. The weight of the bottom counterweight block 1 4 and the bottom counterweight block 2 5 are both 10 kg, and the weight of the suspended counterweight block 3 9 is increased twice within the range of 1 kg-3 kg. The motion parameters of the floating board are shown in Table 3.

[0029] Table 3 It can be seen from Table 3 that the ultimate horizontal displacement and ultimate vertical displacement of the floating board change little. This configuration has good balance, but the floating board may rotate under large water level fluctuations.

[0030] Option 4: If Figure 4 As shown, the fixed pulley 3 8 is connected to the bottom counterweight block 1 4 and the suspended counterweight block 4 10 by a flexible rope to adapt to the scene of large fluctuation of water level. The weight of the bottom counterweight block 1 4 is 10kg, and the weight of the suspended counterweight block 4 10 increases in the range of 2kg-6kg. The motion parameters of the floating board are shown in Table 4.

[0031] Table 4 It can be seen from Table 4 that the maximum vertical displacement and average vertical displacement of the floating board vary greatly. This solution can cope with a larger range of water level fluctuations. In this installation method, the floating board rotates around the center, but may not float normally in some cases.

[0032] The working principle and working process of the automatic lifting device for planting rice on a floating plate of the present invention are briefly described below.

[0033] The present invention relates to an automatic lifting device for planting rice on a floating plate, and in particular to a device which enables the floating plate to float up or sink as the water level changes by automatically adjusting a counterweight block. The device is suitable for use as a floating device for monitoring or controlling the water level in a reservoir, a lake, or other water environment.

[0034] Automatic lifting process: The floating board system does not require any electronic sensors, and completely relies on the self-balancing mechanism of physical principles to achieve automatic lifting and lowering when the water level changes. When the water level rises or falls, the floating board automatically adjusts its height through the gravity of the floating weight block and the pulley system to achieve a quick response and maintain balance.

[0035] Response time: According to experimental data, the shortest response time is 1.02 seconds and the longest is 2.79 seconds. The system will adjust the response time according to the speed of water level changes to ensure that the floating board device can respond quickly.

[0036] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
