[0001] This application belongs to the technical field of paddy field irrigation equipment, specifically relating to a sluice gate system. Background Technology

[0002] In paddy field cultivation of crops such as rice, the control of water intake and drainage during the irrigation process is crucial and directly affects crop growth. Sluice gates are a major component of paddy field irrigation equipment and are used to connect the inlet and outlet pipes.

[0003] In existing technologies, sluice gates are mostly designed for a single function, namely, a drainage gate and a water inlet gate. The drainage gate is connected to the drainage pipe, and the water inlet gate is connected to the water inlet pipe. In other words, water inlet and drainage require different equipment, resulting in higher costs. Summary of the Invention

[0004] The purpose of this application is to provide a sluice gate system designed to reduce the cost of paddy field irrigation equipment.

[0005] To achieve the above objectives, this application provides a sluice gate system, comprising:

[0007] A water inlet gate device includes a water inlet gate body having a water inlet and a water inlet gate for opening and closing the water inlet;

[0008] The opening and closing actuator includes a drive mechanism and a quick-change mechanism. The quick-change mechanism is used to connect the drainage gate to the drive end of the drive mechanism or to connect the inlet gate to the drive end of the drive mechanism. The drive mechanism includes a mechanism housing, a one-way bending rigid chain, and a drive motor. The mechanism housing has an inlet and outlet. The one-way bending rigid chain is driven to rotate by the drive motor and can move vertically in and out of the inlet and outlet. The end of the one-way bending rigid chain that extends out of the inlet and outlet serves as the drive end of the drive mechanism.

[0009] In some embodiments, the drainage gate body is provided with a movable guide rail, and the drainage gate moves in coordination with the movable guide rail.

[0010] In some embodiments, the moving guide rail is made of a material with a low coefficient of friction.

[0011] In some embodiments, the drain gate body is provided with a threaded hole within the extension range of the movable guide rail. The drain gate device also includes a plunger indexing pin, which is threadedly engaged with the threaded hole, and the axial length of the plunger indexing pin is greater than the axial length of the threaded hole.

[0012] In some embodiments, the water inlet gate device includes a water inlet gate body, the water inlet gate being movably disposed within the water inlet gate body, the water inlet gate body being provided with a plunger ball mechanism, the plunger ball mechanism including a locked state of pressing against the water inlet gate and an unlocked state of being separated from the water inlet gate, and the water inlet gate being provided with a switching element for switching between the locked state and the unlocked state.

[0013] In some embodiments, the plunger ball mechanism includes:

[0014] The mechanism housing is installed on the outside of the water inlet gate body, and the water inlet gate body is provided with a locking hole and a moving hole;

[0015] A telescopic top shaft is installed inside the mechanism housing and extends laterally. One end of the telescopic top shaft is provided with a first elastic telescopic member connected to the mechanism housing, and the other end can pass through the locking hole laterally.

[0016] A telescopic locking shaft is installed inside the housing of the mechanism and extends vertically. A snap-fit ​​notch is provided on the telescopic top shaft. A protrusion on the telescopic locking shaft extends through the moving hole into the water inlet gate body. One end of the telescopic locking shaft is provided with a second elastic telescopic member connected to the housing of the mechanism, and the other end can be inserted into the snap-fit ​​notch. The switching member is used to push the protrusion to move vertically. The locked state is when the telescopic locking shaft is inserted into the snap-fit ​​notch, and the unlocked state is when the telescopic locking shaft is separated from the snap-fit ​​notch.

[0017] In some embodiments, the switching element includes a wedge-shaped block with a ramp surface disposed along the telescopic vertical direction toward the telescopic top axis.

[0018] In some embodiments, a guide groove extending laterally is formed within the mechanism housing, along which the unidirectional bending rigid chain can move.

[0019] In some embodiments, the drive mechanism further includes:

[0020] A displacement sensor is mounted on the mechanism housing and connected to the quick-change mechanism;

[0021] The control unit is communicatively connected to both the displacement sensor and the drive motor and is configured as follows:

[0022] The length of the unidirectional bending rigid chain extending from the inlet and outlet is adjusted based on the monitoring data from the displacement sensor.

[0023] In some embodiments, the drive mechanism further includes a telescopic sleeve, one end of which is connected to the mechanism housing and the other end of which is connected to the quick-change mechanism. The telescopic sleeve is fitted over the unidirectional bending rigid chain and the displacement sensor.

When the paddy field needs irrigation, the drainage sluice gate device is connected to the drive mechanism through a quick-change mechanism, and the drive mechanism drives the drainage gate to open. When the paddy field needs drainage, the water intake sluice gate device is connected to the drive mechanism through a quick-change mechanism, and the drive mechanism drives the water intake gate to open. In other words, the sluice gate system of this application integrates the water intake and drainage functions, and only needs to be equipped with one drive mechanism to realize the water intake and drainage functions, thereby significantly reducing the production cost of the sluice gate system. At the same time, the foldable performance of the unidirectional bending rigid chain is used to reduce the volume of the mechanism box, so that the volume and weight of the drive mechanism are reduced, which can also reduce the production cost of the sluice gate system and facilitate the movement and disassembly of the drive mechanism.

[0040] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0041] The terminology of the sluice gate system according to this application is described below with reference to the accompanying drawings.

[0042] like Figures 1 to 7As shown, a specific embodiment of this application provides a sluice gate system, including a drainage sluice gate device 100, an inlet sluice gate device 200, and an opening and closing actuator 300. The drainage sluice gate device 100 includes a drainage gate body 11 with a drainage outlet and a drainage gate 12 for opening and closing the drainage outlet. The inlet sluice gate device 200 includes an inlet gate body 21 with an inlet and an inlet gate 22 for opening and closing the inlet. The opening and closing actuator 300 includes a drive mechanism 31 and a quick-change mechanism. The quick-change mechanism is used to connect the drainage gate 12 to the drive end of the drive mechanism 31 or to connect the inlet gate 22 to the drive end of the drive mechanism 31. The drive mechanism 31 includes a mechanism housing 311, a one-way bending rigid chain 312, and a drive motor 314. The mechanism housing 311 has an inlet and outlet. The one-way bending rigid chain 312 is driven to rotate by the drive motor 314 and can move vertically in and out of the inlet and outlet. The end of the one-way bending rigid chain 312 that can extend out of the inlet and outlet serves as the drive end of the drive mechanism 31.

[0043] In paddy field cultivation of crops such as rice, the control of water intake and drainage during irrigation is crucial and directly affects crop growth. The sluice gate system is a core piece of equipment for paddy field irrigation and is used to connect the inlet and outlet pipes. In this application, a quick-change mechanism is used to switch between the drainage sluice gate device 100 and the inlet sluice gate device 200, thereby enabling the sluice gate system to switch between drainage and inlet functions. Thus, a single drive mechanism 31 can achieve both inlet and drainage functions, significantly reducing the cost of the sluice gate system. Simultaneously, the foldable nature of the unidirectional bending rigid chain 312 is utilized to reduce the volume of the mechanism housing 311, thereby reducing the volume and weight of the drive mechanism 31 and further lowering the production cost of the sluice gate system.

[0044] Specifically, the paddy field is equipped with an inlet pipe for water intake and a drain pipe for drainage. A drain gate device 100 is installed on the drain pipe, and an inlet gate device 200 is installed on the inlet pipe. When the paddy field needs drainage, a quick-change mechanism connects the drive mechanism 31 to the drain gate 12 located at the drain pipe, and the drive mechanism 31 opens and closes the drain gate 12 to open and close the drain outlet on the drain gate body 11, thereby realizing the opening and closing of the drain pipe and thus realizing the water intake function. When the paddy field needs irrigation, a quick-change mechanism connects the drive mechanism 31 to the inlet gate 22 located at the inlet pipe, and the drive mechanism 31 opens and closes the inlet gate 22 to open and close the inlet on the inlet gate body 21, thereby realizing the opening and closing of the inlet pipe and thus realizing the water intake function.

[0045] Furthermore, the drainage gate device 100 is directly installed at the drainage point, and the water inlet gate device 200 is directly installed at the water inlet point. When the corresponding irrigation function is required, the drive mechanism 31 can be selectively connected to either the drainage gate 12 or the water inlet gate 22, thereby increasing the convenience of the gate system. In addition, the smaller size and weight of the mechanism housing 311 also makes it easier to move and disassemble the drive mechanism 31.

[0046] Furthermore, the quick-change mechanism includes a drive-end connecting seat 32, a gate-end connecting seat 33, and a quick-change pin 34. The drive-end connecting seat 32 is installed at the end of the unidirectional bending rigid chain 312 that can extend out of the inlet and outlet. There are two gate-end connecting seats 33, which are respectively installed on the drainage gate 12 and the inlet gate 22. When the paddy field needs to drain water, the quick-change pin 34 passes through the drive-end connecting seat 32 and the gate-end connecting seat 33 on the drainage gate 12 to realize the drainage function of the sluice gate system. When the paddy field needs to be filled with water, the quick-change pin 34 passes through the drive-end connecting seat 32 and the gate-end connecting seat 33 on the inlet gate 22 to realize the water filling function of the sluice gate system. When it is necessary to switch from the drainage function to the water filling function, it is only necessary to disconnect the quick-change pin 34 from the gate-end connecting seat 33 on the drainage gate 12. Pull out the quick-release pin 34 and move the opening / closing actuator 300 to the inlet pipe. Then, connect the quick-release pin 34 through the drive end connector 32 and the gate end connector 33 on the inlet gate 22. When switching from the inlet function to the drainage function, simply pull out the quick-release pin 34 from the gate end connector 33 on the inlet gate 22, move the opening / closing actuator 300 to the drainage pipe, and then connect the quick-release pin 34 through the drive end connector 32 and the gate end connector 33 on the drainage gate 12. As can be seen, the entire disassembly and assembly process is relatively convenient, thus increasing the convenience of the sluice gate system.

[0047] It should be noted that, in the description of this disclosure, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "front," "back," "inner," and "outer," etc., indicating orientation or positional relationships, are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0048] like Figure 3 As shown, in some embodiments, the drainage gate body 11 is provided with a movable guide rail, and the drainage gate 12 moves in coordination with the movable guide rail to ensure the movement stability of the drainage gate body 11.

[0049] Specifically, the drainage gate body 11 includes multiple side plates forming a drainage chamber. Both the front and rear side plates have drainage outlets. The drainage outlet on the rear side plate is connected to a drainage pipe. The drainage gate 12 is inserted between the front and rear side plates to close the drainage outlet on the rear side plate. A moving track is provided on the rear side of the front side plate and the front side of the rear side plate. Corresponding moving sliders are provided on the drainage plates, and these sliders are movably positioned within the moving track.

[0050] Furthermore, the moving guide rail is made of a material with a low coefficient of friction, such as polytetrafluoroethylene, to reduce wear between the moving slider and the moving guide rail.

[0051] In reality, there are situations where the drainage of paddy fields is not completely completed, meaning that a certain water level needs to be maintained. Therefore, the drainage gate 12 is opened from top to bottom and closed from bottom to top. By moving the drainage gate 12 a certain distance from top to bottom, the upper part of the drainage gate 12 is made higher than the water level that the paddy field needs to maintain, thereby achieving the function of maintaining the water level in the paddy field.

[0052] In some embodiments, the height of the drainage gate 12 is adjusted by mechanical adjustment. Specifically, the height of the upper end of the drainage gate 12 is adjusted by the drive mechanism 31 so that the water in the paddy field enters the drainage gate body 11 from above the upper end of the drainage gate 12 and keeps the water level in the paddy field at the height of the upper end of the drainage gate 12.

[0053] like Figure 3 As shown, in some embodiments, the drain gate body 11 is provided with a threaded hole 13, which is within the extension range of the moving guide rail. The drain gate device 100 also includes a plunger indexing pin, which is threadedly engaged with the threaded hole 13, and the axial length of the plunger indexing pin is greater than the axial length of the threaded hole 13.

[0054] Specifically, the threaded hole 13 is opened on the front side plate of the drain gate body 11. The plunger indexing pin is screwed into the threaded hole 13 from front to back and the rear end extends into the drain gate body 11 so as to press against the drain gate 12 and the rear side plate of the drain gate body 11, thereby keeping the drain gate 12 at the required height.

[0055] In fact, in addition to the mechanical adjustment method, the drainage gate device 100 of this application is also equipped with a manual adjustment method. When the drive mechanism 31 used for the mechanical adjustment method is damaged, it is necessary to separate the drive mechanism 31 from the drainage gate 12, that is, pull out the quick-change pin 34, and then use the manual drive method to adjust the height of the drainage gate 12. Specifically, pull the handle on the drainage gate 12 up and down to adjust the height of the drainage gate 12. After the adjustment is in place, screw the plunger indexing pin into the threaded hole 13 so that the plunger indexing pin abuts against the drainage gate 12.

[0056] like Figure 6 As shown, in some embodiments, the water inlet gate device 200 includes a water inlet gate body 21, a water inlet gate 22 is movably disposed within the water inlet gate body 21, a plunger ball mechanism 23 is provided on the water inlet gate body 21, the plunger ball mechanism 23 includes a locked state of pressing against the water inlet gate 22 and an unlocked state of being separated from the water inlet gate 22, and a switching element 24 for switching between the locked state and the unlocked state is provided on the water inlet gate 22.

[0057] Specifically, the inlet gate 22 opens from bottom to top and closes from top to bottom. When the inlet gate 22 opens from bottom to top, the plunger top ball mechanism 23 is switched from the locked state to the unlocked state through the switching component 24. When the inlet gate 22 closes from top to bottom, the plunger top ball mechanism 23 is switched from the unlocked state to the locked state through the switching component 24. When the plunger top ball mechanism 23 is in the unlocked state, the inlet gate 22 can move up and down to adjust the water intake speed. When the plunger top ball mechanism 23 is in the locked state, the inlet gate 22 is fixed.

[0058] like Figure 6 and Figure 8 As shown, in some embodiments, the plunger ball mechanism 23 includes a mechanism housing 231, a telescopic top shaft 232, and a telescopic locking shaft 233. The mechanism housing 231 is installed on the outside of the inlet gate body 21, and the inlet gate body 21 has a locking hole and a moving hole. The telescopic top shaft 232 is installed inside the mechanism housing 231 and extends laterally. One end of the telescopic top shaft 232 is provided with a first elastic telescopic member 234 connected to the mechanism housing 231, and the other end can pass laterally through the locking hole. The telescopic locking shaft 233 is installed in the mechanism housing 231. The telescopic top shaft 232 extends vertically and has a snap-fit ​​notch 235. The telescopic locking shaft 233 has a protrusion 236 that extends through a moving hole into the water inlet gate body 21. One end of the telescopic locking shaft 233 has a second elastic telescopic member 237 that is connected to the mechanism housing 231, and the other end can be inserted into the snap-fit ​​notch 235. The switching member 24 is used to push the protrusion 236 to move vertically. In the locked state, the telescopic locking shaft 233 is inserted into the snap-fit ​​notch 235, and in the unlocked state, the telescopic locking shaft 233 is separated from the snap-fit ​​notch 235.

[0059] Specifically, the water inlet gate body 21 includes multiple side plates forming a water inlet cavity. Both the front and rear side plates have water inlets. The water inlet on the rear side plate is connected to the water inlet pipe. The water inlet gate 22 is inserted between the front and rear side plates to close the water inlet on the rear side plate. The horizontal direction is the front-to-back direction, and the vertical direction is the up-and-down direction.

[0060] The rear side of the mechanism housing 231 is open and installed on the front side of the front side plate. The front side plate has a locking hole and a moving hole. The front end of the telescopic top shaft 232 is provided with a first elastic telescopic member 234 connected to the mechanism housing. The rear end of the telescopic top shaft 232 can pass through the locking hole in the front-back direction. The snap-fit ​​notch 235 is set downward. The lower end of the telescopic lock shaft 233 is provided with a second elastic telescopic member 237 connected to the mechanism housing 231. The upper end of the telescopic lock shaft 233 can be inserted into and pulled out of the snap-fit ​​notch 235 in the up-down direction. The protrusion 236 extends to the right and passes through the moving hole. The switching member 24 is set on the front side of the water inlet gate 22.

[0061] The downward movement of the drain gate 12 drives the switching member 24 to push the protrusion 236 downward, so that the telescopic lock shaft 233 is pulled downward out of the locking recess 235. This causes the telescopic top shaft 232 to be pushed forward by the first elastic telescopic member 234 to extend out of the locking hole and push the drain gate 12 against the rear side plate, thereby switching to the locked state and fixing the drain gate 12. The upward movement of the drain gate 12 drives the switching member 24 to push the telescopic top shaft 232 to the right, so that the locking recess 235 moves to align with the telescopic lock shaft 233. This causes the telescopic top shaft 232 to be pushed upward by the second elastic telescopic member 237 to insert into the locking recess 235, thereby switching to the unlocked state and allowing the drain gate 12 to move freely.

[0062] Furthermore, the bottom surface of the wedge block is used to push the protrusion 236 to move, and the switching member 24 includes a wedge block with a ramp surface facing upward, so that the wedge block can push the telescopic top shaft 232 to retract to the right into the mechanism housing 231, thereby improving the reliability of the drainage gate device 100.

[0063] like Figure 7 As shown, in some embodiments, a guide groove 313 extending laterally is formed inside the mechanism housing 311, allowing movement along the guide groove 313.

[0064] Specifically, the horizontal direction is left-right, and the vertical direction is up-down. The unidirectional bending rigid chain 312 is composed of multiple specially designed links and can only bend in one direction. By setting the guide groove 313, the starting end and free end of the unidirectional bending rigid chain 312 are set on the same vertical line extending in the up-down direction. The unidirectional bending rigid chain 312 can be driven to rotate by the drive motor 314, so that the free end of the unidirectional bending rigid chain 312 can extend out of the inlet and outlet of the mechanism housing 311 and enter the inlet and outlet of the mechanism housing 311, thereby driving the quick-change mechanism to move, and thus realizing the movement of the drainage gate 12 and the water inlet gate 22.

[0065] Furthermore, the guide groove 313 limits the movement path of the unidirectional bending rigid chain 312, thereby enabling the unidirectional bending rigid chain 312 to have efficient and stable operation during operation, thus improving the stability of the quick-change mechanism during movement.

[0066] Furthermore, the links of the unidirectional bending rigid chain 312 are tightly fitted together and can be completely housed within the mechanism housing 311. The mechanism housing 311 extends in the left and right directions and has a relatively small height in the up and down directions. In other words, it achieves a storage effect with a very small volume, thereby greatly reducing the space occupied by the opening and closing actuator 300 in the up and down directions, and thus adapting to the limited space environment of paddy fields.

[0067] like Figure 7 As shown, in some embodiments, the drive mechanism 31 further includes a displacement sensor and a control unit. The displacement sensor is mounted on the mechanism housing 311 and connected to the quick-change mechanism. The control unit is communicatively connected to both the displacement sensor and the drive motor 314 and configured to adjust the length of the unidirectional bending rigid chain 312 extending out of the inlet and outlet according to the monitoring data of the displacement sensor.

[0068] Specifically, when the drainage gate 12 or the inlet gate 22 moves up and down, the displacement sensor converts the displacement signal into an electrical signal and transmits it to the control unit to provide real-time feedback and display of the positions of the drainage gate 12 and the inlet gate 22. At the same time, the control unit realizes automatic adjustment of the positions of the drainage gate 12 and the inlet gate 22, and cooperates with the automatic position feedback of the displacement sensor to improve the accuracy of the drive mechanism 31 in driving the drainage gate 12 and the inlet gate 22.

[0069] Furthermore, the drive mechanism 31 also includes a telescopic sleeve 315. One end of the telescopic sleeve 315 is connected to the mechanism housing 311, and the other end is connected to the quick-change mechanism. The telescopic sleeve 315 is sleeved on the unidirectional bending rigid chain 312 and the displacement sensor to protect the unidirectional bending rigid chain 312 and the displacement sensor. The telescopic sleeve 315 can extend and retract with the movement of the quick-change mechanism.
