Description

Technical Field

[0001] This application relates to the technical field of automatic water allocation devices for reservoir irrigation areas, specifically an automatic water allocation device for reservoir irrigation areas. Background Technology

[0002] An irrigation district refers to an irrigation area with a reliable water source and a system of water diversion, transportation, and distribution channels and corresponding drainage ditches. It is a product of human economic activities and develops along with the development of society and economy. The automatic allocation of water in reservoir irrigation districts mainly relies on advanced water-saving technologies and intelligent management systems to achieve the optimal allocation and efficient utilization of water resources through automation and intelligence.

[0003] For example, Chinese Patent (Announcement No.: CN220284739U) discloses an automatic water allocation device for irrigation areas, including a water channel. A valve frame is fixedly connected to the outside of the water channel. A guide frame is fixedly connected to the lower part of the valve frame. A hydraulic rod is fixedly connected to the upper part of the valve frame. A pressure plug is fixedly connected to the lower end of the hydraulic rod. A valve is slidably installed between the valve frame and the guide frame. The upper part of the valve slides through the valve frame. A worm gear is threadedly installed on the upper part of the valve. The worm gear is rotatably installed on the valve frame. Then, a waterproof motor drives the worm to rotate, which in turn drives the worm gear to rotate, causing the worm gear to raise or lower the valve. When the valve lowers, the highest water level of the reservoir is reduced. When the valve rises, the highest water level of the reservoir is increased, so that the reservoir automatically maintains the highest water level. After the valve is adjusted, the hydraulic rod extends and drives the pressure plug between the valve and the guide frame, causing the valve to press further against the valve frame, improving the sealing degree, thereby facilitating the control of the highest water level of the reservoir.

[0004] However, the aforementioned patent has some shortcomings. It seals the valve by pressing the valve backward with a plug. The plug contacts the center of the valve's front side and applies pressure backward, while the baffle contacts the four sides of the valve's back side and provides support, creating a counterforce. The forces on the front and back sides of the valve are not applied to the same axis. Under prolonged pressure sealing, the valve will bend backward, forming an arc surface and causing the valve's sides to warp, thus affecting the seal between the valve and the baffle. This can easily lead to water leakage and inconvenience in use. Therefore, an automatic water allocation device for reservoir irrigation areas is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an automatic water allocation device for reservoir irrigation areas, which has advantages such as good sealing performance and solves the problem that the devices disclosed in the aforementioned searched patents are prone to deformation after long-term use, leading to poor sealing performance.

[0006] To achieve the above objectives, this application provides the following technical solution: an automatic water allocation device for a reservoir irrigation area, comprising two columns, a baffle fixed between the two columns, two guide plates slidably connected to opposite sides of the two columns, a valve plate fixed between the two guide plates, a top chamber fixed to the top surface of the two columns, an adjustment mechanism disposed on the valve plate, and a squeezing mechanism disposed on the valve plate, wherein guide grooves are provided on opposite sides of the two columns;

[0007] The adjustment mechanism includes a rack fixed to the opposite sides of the two guide plates, a plurality of rotating rods rotatably connected between the front and rear inner walls of the guide groove, an adjustment gear fixed to the outer peripheral wall of the rotating rod and meshing with the rack, a worm gear rotatably connected to the inner bottom wall of the guide groove, a worm wheel fixed to the outer peripheral wall of the rotating rod and meshing with the worm gear, and a drive assembly disposed in the top compartment.

[0008] Using the above technical solution, during use, the valve plate slides up and down in conjunction with the guide plate through the set adjustment mechanism, thereby changing the drainage height of the baffle and achieving the effect of automatically regulating the water level of the reservoir. The guide plate is driven by the cooperation of the adjusting gear and rack, so that the valve plate can be finely adjusted back and forth within a certain range, which facilitates better sealing of the valve plate with the baffle and ensures the sealing performance of the automatic water volume allocation device.

[0009] Furthermore, the drive assembly includes a dual-axis motor fixed to the bottom wall of the top compartment, transmission rods fixed to the ends of the output shafts on the left and right sides of the dual-axis motor, a main bevel gear fixed to the outer peripheral wall of the transmission rod, and a driven bevel gear fixed to the top of the worm gear and meshing with the main bevel gear.

[0010] Using the above technical solution, the adjustment mechanism is driven by a dual-axis motor in the drive assembly. When in use, the dual-axis motor is started, and the dual-axis motor drives the worm gears on both sides to rotate through the transmission rod. Then, the connecting worm gears drive the adjustment gears on both sides to rotate synchronously in opposite directions, so as to achieve the effect of adjusting the valve plate up and down.

[0011] Furthermore, the extrusion mechanism includes two extrusion plates slidably connected to the back of the valve plate, four guide blocks respectively fixed to the front of the two extrusion plates, two triangular plates respectively fixed to the opposite sides of the two extrusion plates, and a control component disposed on the valve plate. A rectangular groove is provided on the back of the valve plate.

[0012] Using the above technical solution, when the valve plate needs to be adjusted to move up and down, the extrusion mechanism can drive the two extrusion plates on both sides to contract, so that the valve plate is no longer extruded forward. This reduces the friction between the valve plate and the baffle and improves the convenience of adjustment. After the valve plate is adjusted, the extrusion plates are driven to move in opposite directions, so that the two extrusion plates move to the back of the valve plate near the left and right sides. This, together with the baffle, forms an extrusion seal on the two sides of the valve plate, enhancing the sealing effect and making it less likely for the valve plate to deform.

[0013] Furthermore, the control assembly includes a control motor fixed to the inner wall of the rectangular groove, two bidirectional screws rotatably connected between the inner walls of the left and right sides of the rectangular groove, a transmission gear fixed to the bottom bidirectional screw and the output shaft of the control motor, a transmission wheel fixed to the outer peripheral wall of the bidirectional screw, and a belt disposed between the two transmission wheels. The two transmission gears mesh with each other, and the bidirectional screw passes through the guide block and is threadedly connected to it.

[0014] Using the above technical solution, the extrusion mechanism is driven by a control motor set in the control component. After the valve plate is adjusted, the control motor is started. The control motor drives the two extrusion plates to slide steadily back to back through two bidirectional screws, so that the triangular plate on the side of the extrusion plate is inserted into the guide groove and abuts against its rear inner wall. Then, the triangular plate and the extrusion plate form a forward extrusion force on both sides of the valve plate to seal it.

[0015] Furthermore, the valve plate is disposed on the back of the baffle, the front of the baffle is provided with a drain hole, and the back of the baffle is fixed with an annular rubber sealing gasket.

[0016] By adopting the above technical solution, the drainage holes facilitate the overflow of water inside the reservoir after it reaches the water level line, and the annular rubber sealing gasket improves the sealing effect between the baffle and the valve plate.

[0017] Furthermore, the top compartment is connected to the two columns in an inverted U-shape, and the guide groove is used for the guide plate to slide up and down inside it.

[0018] The above technical solution facilitates the stable up-and-down movement of the valve plate through the set adjustment mechanism, thereby changing the reservoir's drainage height.

[0019] Furthermore, multiple rotating rods are distributed equidistantly in the same guide groove, the top end of the worm gear extends into the interior of the top compartment and is rotatably connected to its inner bottom wall, and the opposite ends of the two transmission rods are rotatably connected to the left and right inner walls of the top compartment, respectively.

[0020] The above technical solution facilitates the increase of stability during the rotation of the rotating rod and transmission rod.

[0021] Furthermore, the triangular plate is a right-angled triangular plate, with the inclined surface of the triangular plate facing the rear inner wall of the guide groove. The two extrusion plates are positioned opposite each other, and the four guide blocks are respectively located near the four corners of the front of the rectangular groove. The two guide blocks that are opposite each other are threadedly connected to the same bidirectional screw.

[0022] The above technical solution facilitates the movement of the extrusion plates on both sides relative to each other or in opposite directions by using two bidirectional screws and four guide blocks.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] 1. In use, the automatic water allocation device for the reservoir irrigation area allows the valve plate to slide up and down in conjunction with the guide plate through the set adjustment mechanism, thereby changing the drainage height of the baffle and achieving the effect of automatically regulating the reservoir water level. The guide plate is driven by the cooperation of the adjusting gear and rack, so that the valve plate can be finely adjusted back and forth within a certain range, which facilitates better sealing of the valve plate with the baffle and ensures the sealing performance of the automatic water allocation device.

[0025] 2. When the automatic water allocation device for the reservoir irrigation area needs to adjust the up and down movement of the valve plate, the squeezing mechanism can drive the squeezing plates on both sides to contract, so that the valve plate is no longer squeezed forward. This reduces the friction between the valve plate and the baffle and improves the convenience of adjustment. After the valve plate is adjusted, the squeezing plates are driven to move in opposite directions, so that the two squeezing plates move to the back of the valve plate near the left and right sides. This, together with the baffle, forms a squeezing seal on the two sides of the valve plate, enhancing the sealing effect and making it less likely for the valve plate to deform.

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] Please see Figures 1 to 2 This embodiment of an automatic water allocation device for a reservoir irrigation area includes two columns 1, a baffle 2 fixed between the two columns 1, two guide plates 3 slidably connected to opposite sides of the two columns 1, a valve plate 4 fixed between the two guide plates 3, a top chamber 5 fixed to the top surface of the two columns 1, an adjustment mechanism on the valve plate 4, and a pressing mechanism on the valve plate 4. Guide grooves 6 are provided on opposite sides of the two columns 1. The valve plate 4 is located on the back of the baffle 2. A drainage hole is provided on the front of the baffle 2, and an annular rubber sealing gasket is fixed to the back of the baffle 2. The top chamber 5... The device is connected to the two columns 1 in an inverted U-shape. The guide groove 6 is used for the guide plate 3 to slide up and down inside it. When in use, the device is installed at the drain outlet of the reservoir. When the water level in the reservoir reaches the position of the drain hole on the baffle 2, it can overflow from the drain hole. The valve plate 4 slides up and down with the guide plate 3 through the set adjustment mechanism, thereby changing the drainage height of the baffle 2 and achieving the effect of automatically regulating the water level of the reservoir. After the valve plate 4 is adjusted, the squeezing mechanism works with the baffle 2 to form a squeezing seal on both sides of the valve plate 4, which enhances the sealing effect and also makes it less likely for the valve plate 4 to deform.

[0033] It should be noted that the control method of this application is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this application is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail here.

[0034] Please see Figures 1 to 3The adjustment mechanism includes racks 701 fixed on opposite sides of two guide plates 3, multiple rotating rods 702 rotatably connected between the front and rear inner walls of the guide groove 6, adjusting gears 703 fixed on the outer peripheral wall of the rotating rods 702 and meshing with the racks 701, worms 704 rotatably connected to the inner bottom wall of the guide groove 6, worm wheels 705 fixed on the outer peripheral wall of the rotating rods 702 and meshing with the worms 704, and a drive assembly located in the top tank 5. When it is necessary to adjust the highest water level of the reservoir, the drive assembly drives the two worms 704 to drive the worm wheels 705 on both sides to rotate synchronously in opposite directions. The worm wheels 705 drive the rotating rods 702 to rotate, and the rotating rods 702 drive the adjusting gears 703 on both sides to rotate synchronously in opposite directions. This causes the adjusting gears 703 on both sides to drive the racks 701 on both sides to move up and down. The racks 701 drive the guide plates 3 to slide up and down inside the guide groove 6, thereby driving the valve plates 4 to move up and down to adjust the highest water level of the reservoir.

[0035] It should be understood that the guide plate 3 is driven by the adjustment gear 703 and the rack 701. Since there is a certain gap between the front and rear sides of the guide plate 3 and the inner walls of the front and rear sides of the guide groove 6, the valve plate 4 can be finely adjusted back and forth to a certain extent, which makes it easier for the valve plate 4 to fit better with the baffle 2 for sealing and ensure the sealing performance of the automatic water volume configuration device.

[0036] Please see Figures 1 to 3 In this embodiment, the drive assembly includes a dual-axis motor 706 fixed to the bottom wall of the top chamber 5, transmission rods 707 fixed to the output shaft ends on both sides of the dual-axis motor 706, a main bevel gear 708 fixed to the outer peripheral wall of the transmission rod 707, and a driven bevel gear 709 fixed to the top of the worm gear 704 and meshing with the main bevel gear 708. In use, the dual-axis motor 706 is started, which drives the two transmission rods 707 to rotate. The transmission rods 707 drive the main bevel gear 708 to rotate, the main bevel gear 708 drives the driven bevel gear 709 to rotate, and the driven bevel gear 709 drives the worm gear 704 to rotate. The height of the regulating mechanism can be adjusted by the worm gear 704. The operation is simple and convenient, and the practicality is better.

[0037] In this embodiment, multiple rotating rods 702 are distributed at equal intervals in the same guide groove 6, the top end of the worm gear 704 extends into the top chamber 5 and is rotatably connected to its inner bottom wall, and the opposite ends of the two transmission rods 707 are rotatably connected to the left and right inner walls of the top chamber 5 respectively.

[0038] Please see Figures 2 to 4In this embodiment, the extrusion mechanism includes two extrusion plates 801 slidably connected to the back of the valve plate 4, four guide blocks 802 respectively fixed to the front of the two extrusion plates 801, two triangular plates 803 respectively fixed to the opposite sides of the two extrusion plates 801, and a control component disposed on the valve plate 4. A rectangular groove 804 is provided on the back of the valve plate 4. After the valve plate 4 is adjusted, the control component drives the guide blocks 802 on both sides to slide synchronously in opposite directions, thereby driving the two extrusion plates 801 to move in opposite directions, and causing the triangular plates 803 on the side of the extrusion plates 801 to insert into the guide groove 6 and abut against its rear inner wall. Then, the triangular plates 803 and the extrusion plates 801 form a forward extrusion force on both sides of the valve plate 4, and cooperate with the annular rubber sealing gasket on the baffle 2 for sealing.

[0039] Please see Figures 2 to 4 In this embodiment, the control component includes a control motor 805 fixed on the inner wall of the rectangular groove 804, two bidirectional screws 806 rotatably connected between the inner walls of the left and right sides of the rectangular groove 804, a transmission gear 807 fixed on the bottom bidirectional screw 806 and the output shaft of the control motor 805, a transmission wheel 808 fixed on the outer peripheral wall of the bidirectional screw 806, and a belt 809 disposed between the two transmission wheels 808. The two transmission gears 807 mesh with each other. The bidirectional screw 806 passes through the guide block 802 and is threadedly connected to it. In use, the control motor 805 is started, and the control motor 805 drives the bottom bidirectional screw 806 to rotate through the two meshing transmission gears 807. The bottom bidirectional screw 806 drives the top bidirectional screw 806 to rotate through the transmission wheel 808 and the belt 809. Furthermore, the two bidirectional screws 806 drive the guide blocks 802 on both sides to slide synchronously in opposite directions, so that the triangular plate 803 can be inserted into the guide groove 6 for compression and sealing.

[0040] In this embodiment, the triangular plate 803 is a right-angled triangular plate, the inclined surface of the triangular plate 803 faces the rear inner wall of the guide groove 6, the two extrusion plates 801 are opposite each other, and the four guide blocks 802 are respectively close to the four corners of the front of the rectangular groove 804. The two guide blocks 802 opposite each other are threadedly connected to the same bidirectional screw 806.

[0041] The working principle of the above embodiments is as follows:

[0042] (1) When in use, start the dual-axis motor 706. The dual-axis motor 706 drives the two transmission rods 707 to rotate. The transmission rods 707 drive the main bevel gear 708 to rotate. The main bevel gear 708 drives the secondary bevel gear 709 to rotate. The secondary bevel gear 709 drives the worm gear 704 to rotate. Furthermore, the two worm gears 704 drive the worm wheels 705 on both sides to rotate synchronously in opposite directions. The worm wheels 705 drive the rotating rod 702 to rotate. The rotating rod 702 drives the adjusting gears 703 on both sides to rotate synchronously in opposite directions. This causes the adjusting gears 703 on both sides to drive the racks 701 on both sides to move up and down. The racks 701 drive the guide plate 3 to slide up and down inside the guide groove 6, thereby driving the valve plate 4 to move up and down to adjust the highest water level of the reservoir.

[0043] (2) After the valve plate 4 is adjusted, start the control motor 805. The control motor 805 drives the bottom bidirectional screw 806 to rotate through two meshing transmission gears 807. The bottom bidirectional screw 806 drives the top bidirectional screw 806 to rotate through the transmission wheel 808 and belt 809. Furthermore, the two bidirectional screws 806 drive the guide blocks 802 on both sides to slide synchronously in opposite directions, thereby driving the two extrusion plates 801 to move in opposite directions, and causing the triangular plate 803 on the side of the extrusion plate 801 to insert into the guide groove 6 and abut against its rear inner wall. Then, the triangular plate 803 and the extrusion plate 801 form a forward extrusion force on both sides of the valve plate 4, and cooperate with the annular rubber sealing gasket on the baffle 2 for sealing.
