Description

Technical Field

[0001] This invention relates to the field of rice cultivation management devices, specifically a simplified rice cultivation water layer management device. Background Technology

[0002] Rice is my country's largest grain crop. Traditional rice production requires sowing and raising seedlings in seedling sheds or ponds. After the seedlings grow for a period of time (about one month) and reach a certain height, they are then removed from the seedbeds and transplanted into paddy fields. This seedling raising process involves many steps, requires a lot of labor, is costly, and is quite arduous. Moreover, seedling management requires high standards, involves many steps, and takes a long time. Poor management can easily lead to seedling diseases (damping-off disease) and problems, resulting in low-quality seedlings that are slow to grow after transplanting, causing yield reduction. Direct seeding of rice, on the other hand, is a cultivation method that directly sows seeds in the paddy field. This eliminates the seedling raising and transplanting steps, greatly saving labor costs. However, due to factors such as climate, seed quality, and inadequate management, direct seeding technology for rice still faces some challenges.

[0003] While simplified rice cultivation eliminates the need for sowing and seedling raising in seedling sheds or ponds, it also increases the requirements for water level management during cultivation. Real-time monitoring of paddy field water depth and timely control of water inflow and outflow become essential requirements for simplified cultivation. Existing hydroelectric water level monitoring and management equipment is installed inside the paddy field for real-time monitoring. However, due to the loose soil in paddy fields, the soil at the bottom of the equipment is easily washed away, causing the equipment to tilt and affecting the accuracy of water level data collection. This results in inaccurate data and affects the effectiveness of water level management. Furthermore, the fixed location of existing monitoring devices makes it impossible to obtain accurate and true water level status based on data collected from multiple locations. When monitoring water level changes at different locations in the paddy field is required, multiple monitoring devices need to be set up, which is costly and ineffective. Summary of the Invention

[0004] In view of the shortcomings of existing simplified rice cultivation methods mentioned in the background art, the present invention provides a water layer management device for simplified rice cultivation.

[0005] This invention provides the following technical solution: a simplified rice cultivation water layer management device, comprising a control crossbar, a floating port in the center of the control crossbar, connectors on both tubes of the control crossbar, and a rotary control device fixedly connected to the crossbar via the connectors, an air bladder ball fixedly connected to the outside of the rotary control device, an air outlet on the outside of the air bladder ball, an inflation device at the top of the air bladder ball, a vertical rod movably sleeved in the center of the floating port, a floating area fixedly connected to the top of the vertical rod, an upper limit plate fixedly installed at the bottom of the floating area, a lower limit plate fixedly installed at the top of the floating area, a counterweight ball fixedly connected to the bottom of the vertical rod, and a rotary control device... The device includes a rotating outer cylinder and a rotating inner column. The rotating inner column is movably sleeved in the middle of the rotating outer cylinder. A spiral groove is formed on the upper side of the inner wall of the rotating outer cylinder. A threaded groove matching the spiral groove is formed on the outer wall of the rotating inner column. A control groove is formed on the lower side of the inner wall of the rotating outer cylinder. A movable plate is movably arranged at the bottom of the rotating inner column. Spring buckles are fixedly installed at both ends of the movable plate. The control groove includes two sets, one near the upper side and one near the lower side. A pressure button is provided in the control groove. A pressure button is fixedly installed on the upper surface of the control crossbar near the floating port. A reset airbag is provided inside the airbag ball. The reset airbag extends to the bottom end of the rotating outer cylinder.

[0006] Preferably, the floating area is defined by the distance between the upper and lower limit plates and slides up and down in the floating opening.

[0007] Preferably, when the spring clip extends, it engages with the control groove, pressing the touch button inside the control groove.

[0008] Preferably, the distance by which the inner column rotates inward after the plumb rod is tilted by 30 degrees is consistent with the distance between the upper set of control slots and the end face of the inner column when the plumb rod is vertical. The distance by which the inner column rotates inward after the plumb rod is tilted by 60 degrees is consistent with the distance between the lower set of control slots and the end face of the inner column when the plumb rod is vertical.

[0009] Preferably, the length of the reset airbag in its inflated state is consistent with the distance from the bottom end of the rotating outer cylinder to a set of control slots on the upper side.

[0010] Preferably, the pressure button near the upper set of control slots controls the water inlet switch to be turned on, and the pressure button near the lower set of control slots controls the issuance of a water leakage warning signal.

[0011] The present invention has the following beneficial effects:

[0012] 1. This invention utilizes an airbag to suspend the entire device on the surface of the paddy field, preventing soil loss at the bottom of the device and thus avoiding tilting that could affect its operation; it also uses the different states of the plumb line at different water levels to detect and control the water level; and it uses the airflow from the air outlet to propel the device to move freely in the paddy field, monitoring the water level at different locations in real time.

[0013] 2. This invention uses airbags on both sides of the device to suspend the entire device on the surface of the paddy field by utilizing the buoyancy generated by the airbags. This avoids the problem of the device tilting due to the soft soil of the paddy field at the bottom of the device and the loss of soil at the bottom of the device, which would affect the accuracy of the detection.

[0014] 3. This invention uses the different states of a plumb bob at different water levels to detect and control the water level. When the water level is too high, the plumb bob floats downward and presses the switch to send a drainage signal. When the water level is too low, the plumb bob tilts and generates torque to send a water replenishment signal, thereby achieving the effect of monitoring the water level and controlling the inflow and outflow of water in the field.

[0015] 4. This invention sets an inflation device at the top of the airbag and an air outlet device on one side of it. The airflow from the outlet propels the device to move freely in the paddy field, allowing for real-time monitoring of water levels at different locations. This avoids sudden changes in water level caused by terrain factors, which could affect the overall control results and make water layer management more effective. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-2 A simplified water layer management device for rice cultivation includes a control crossbar 1. A floating opening 13 is located in the center of the control crossbar 1. Connectors 12 are provided on both pipes of the control crossbar 1, and a rotary control device 2 is fixedly connected to the two pipes via the connectors 12. An airbag ball 3 is fixedly connected to the outside of the rotary control device 2. A vertical rod 4 is movably sleeved in the middle of the floating opening 13. A floating area 5 is fixedly connected to the top of the vertical rod 4. An upper limit plate 51 is fixedly installed at the bottom of the floating area 5, and a lower limit plate 52 is fixedly installed at the top of the floating area 5. The floating area 5 slides vertically within the floating opening 13, with the distance between the upper limit plate 51 and the lower limit plate 52 serving as the boundary. The vertical rod 4... A counterweight ball 6 is fixedly connected to the bottom. When the device is placed on water, the airbag balls 3 on both sides provide buoyancy so that the device floats on the surface of the liquid. It does not need to be fixed to the bottom of the soil and will not tilt due to the soft soil. When the water level is higher than the length of the plumb line 4, the plumb line 4 falls downward due to the influence of the counterweight ball 6 at its bottom. It contacts and presses against the upper surface of the control crossbar 1 on the lower limit plate 52 on the upper side of the floating area 5. A pressure button is fixedly installed on the upper surface of the control crossbar 1 near the floating opening 13. When the lower limit plate 52 presses this pressure button, a signal is sent to close the water inlet switch and perform drainage operation to avoid the problem of waterlogging and lack of oxygen in rice caused by excessive water level in the field.

[0025] Please see Figure 3-4The rotation control device 2 includes a rotating outer cylinder 21 and a rotating inner column 22. The rotating inner column 22 is movably sleeved in the middle of the rotating outer cylinder 21. A spiral groove 23 is provided on the upper side of the inner wall of the rotating outer cylinder 21. A threaded groove matching the spiral groove 23 is provided on the outer wall of the rotating inner column 22, allowing the rotating inner column 22 to freely extend and retract within the rotating outer cylinder 21 along the spiral groove 23 as it rotates. A control groove 25 is provided on the lower side of the inner wall of the rotating outer cylinder 21. A movable plate 26 is movably provided at the bottom of the rotating inner column 22. Spring clips are fixedly installed at both ends of the movable plate 26. When the spring clips extend, they engage with the control groove 25. The control groove 25 includes two sets, one near the upper side and one near the lower side. After the vertical rod 4 is tilted 30 degrees, the rotating inner column 22 rotates and retracts by a certain distance. The distance between the upper set of control slots 25 and the end face of the rotating inner column 22 when the vertical rod 4 is vertical is the same. The distance by which the rotating inner column 22 rotates and retracts after the vertical rod 4 is tilted at 60 degrees is the same as the distance between the lower set of control slots 25 and the end face of the rotating inner column 22 when the vertical rod 4 is vertical. An air outlet 31 is provided on the outer side of the airbag ball 3. When the airbag ball 3 is inflated at the top, air is expelled from the air outlet 31, thereby pushing the whole device forward and realizing real-time monitoring of water level at different locations in the paddy field. A reset airbag 32 is provided on the inner side of the airbag ball 3. The reset airbag 32 extends into the bottom end of the rotating outer cylinder 21, and the length of the reset airbag 32 in the inflated state is the same as the distance between the bottom end of the rotating outer cylinder 21 and the upper set of control slots 25.

[0026] Please see Figure 5-6 The control groove 25 is equipped with a pressure-sensitive button. When the water level is lower than the length of the plumb line 4, the bottom of the counterweight ball 6 contacts the bottom soil. The length of the plumb line 4 is greater than the water level height, causing the control crossbar 1 and the counterweight ball 6 to shift in the vertical plane. The floating area 5 twists the control crossbar 1, causing the rotating inner column 22 to rotate relative to the rotating outer cylinder 21 and move along the spiral groove 23 into the rotating outer cylinder 21. This pushes the moving plate 26 to compress the reset airbag 32 and move it downward. When the moving plate 26 moves to a position close to the upper set of control grooves 25, the pressure-sensitive button here is pressed to control the opening of the water inlet switch, replenishing water to the paddy field until the water level returns to normal. After that, the counterweight ball 6... With the assistance of force, the plumb rod 4 returns to a vertical position, which in turn drives the rotating inner column 22 to rotate outward. The moving plate 26, which is no longer squeezed by the rotating inner column 22, is released from the control groove 25 and resets under the unilateral force of the reset airbag 32. The pressure switch is no longer squeezed, thus stopping the water replenishment operation of the paddy field. When water leakage occurs in the paddy field, the water level in the field drops rapidly to a low level. The plumb rod 4 tilts and pressurizes, twisting the rotating inner column 22 to move deeper into the rotating outer cylinder 21, pushing the moving plate 26 to the control groove 25 near the lower group. The pressure button at the lower control groove 25 is pressed, controlling the device to issue a water leakage warning signal, reminding relevant personnel to check and deal with the field dam.

[0027] In addition, the plumb rod 4 component in this application can be replaced with a telescopic movable plumb rod 4, and equipped with a motor to control its extension and retraction length, thereby realizing the free change of the liquid level control height at different stages of rice growth, so that it can be applied to the entire stage of rice cultivation.

[0028] The signal emitted by this device can be used to provide voice or alarm sounds through an external sounding device, or it can be sent to an indoor terminal via the network for real-time notification. This application does not limit the type of signal.

[0029] The working principle of the method of using this invention is as follows:

[0030] In use, the device is placed in a paddy field. The airbag 3 floats on the surface of the water due to buoyancy, and the plumb rod 4 hangs vertically due to the weight of the bottom counterweight 6. When the water level in the paddy field is at the set height, the inflated state of 32 pushes the rotating inner column 22 outward, maintaining the vertical position of the control bar 1 and the plumb rod 4. When the water level in the paddy field is too high, the airbag 3 floats upward, so that the counterweight 6 is suspended and does not contact the bottom soil. At this time, the floating area 5 slides down 13, and 52 presses 1. 3. The pressure button at the top of the device signals to close the water inlet switch and initiate drainage to prevent waterlogging and oxygen deficiency in the rice paddies caused by excessively high water levels. When the water level in the paddy field is too low, the counterweight ball 6 contacts the bottom soil. The low water level causes the airbag ball 3 to drift to one side, the plumb rod 4 to tilt, and the twisting control bar 1 to rotate, which in turn drives the rotating inner column 22 to rotate. Under the guidance of the spiral groove 23, the rotating inner column 22 extends and retracts towards the rotating outer cylinder 21, pushing... The movable plate 26 moves down to the upper control slot 25 and presses the touch button there to open the water inlet switch, replenishing water to the paddy field until the water level returns to normal. Then, with the help of the counterweight ball 6, the plumb rod 4 returns to a vertical position, which in turn drives the rotating inner column 22 to rotate outward. The movable plate 26, no longer squeezed by the rotating inner column 22, is released from the control slot 25 and resets under the unilateral force of the reset airbag 32. The touch switch is no longer squeezed, thus stopping the water replenishment operation to the paddy field. When water leakage occurs in the paddy field, the water level in the field drops rapidly to a low level. The plumb rod 4 tilts and increases pressure, twisting the rotating inner column 22 to move deeper into the rotating outer cylinder 21, pushing the movable plate 26 to the control slot 25 near the lower control slot. The touch button at the lower control slot 25 is pressed, controlling the device to issue a water leakage warning signal, reminding relevant personnel to check and deal with the paddy field. After the liquid level is restored, the plumb rod 4 returns to a vertical position, continuously monitoring the liquid level in the paddy field.
