Description

Technical Field

[0001] This utility model relates to a water diversion gate, specifically a water diversion gate for irrigation channels that prevents falls, and belongs to the field of irrigation channel technology. Background Technology

[0002] With the advancement of high-standard farmland water conservancy projects in my country, especially the increasing demand for irrigation in irrigation districts, significant challenges have been brought to efficient irrigation in these areas. In the construction of farmland water conservancy projects, main canals are built to promote water-saving irrigation facilities. Water diversion gates are typically installed at the junctions of main and branch canals to regulate and control irrigation water levels in the farmland.

[0003] According to patent CN220079915U, an anti-fall irrigation channel water diversion gate is disclosed, which includes an installation frame, a gate plate slidably connected inside the installation frame, a winding device installed on the top of the installation frame, and anti-fall mechanisms provided on both sides of the front of the installation frame. The anti-fall mechanism includes a sleeve, a sliding rod slidably connected through the bottom of the sleeve, and a magnetic plate fixedly connected to the top of the sliding rod.

[0004] The above-mentioned solution can slow down the descent speed of the gate when the rope breaks during the lifting of the gate by the winding device, thus improving the protection performance of the gate and the mounting frame. However, during the implementation of the above-mentioned solution, it is inconvenient to clean up stones and other debris below the gate. When the gate is closed, stones and other debris in the groove below it can easily obstruct the closure of the gate, resulting in incomplete closure and affecting the water diversion effect of the device. Therefore, we provide a fall-proof irrigation channel water diversion gate to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a fall-proof irrigation canal diversion gate in order to solve the above-mentioned problems, thereby solving the problem in the prior art that it is difficult to clear stones and other debris below the gate before the gate is closed.

[0006] This utility model is achieved through the following technical solution: a fall-proof irrigation canal diversion gate, comprising an irrigation canal, a supporting gate frame fixedly connected to the top surface of the irrigation canal, a diversion gate slidably connected inside the irrigation canal, the diversion gate being slidably connected to the supporting gate frame, a lifting screw rotatably connected to the top surface of the diversion gate, a driving mechanism for driving the lifting screw being provided on the top surface of the supporting gate frame, a limit groove being provided on the outer surface of the diversion gate, a translation plate slidably connected to the outer surface of the diversion gate, a cleaning shovel plate being fixedly connected to the bottom end of the translation plate, and two supporting slides fixedly connected inside the irrigation canal.

[0007] Preferably, two limiting slide rods are fixedly connected to the outer surface of the translation plate, and the two limiting slide rods slide inside the two supporting slides respectively. The supporting slides and the limiting slide rods have the effect of limiting the movement of the translation plate.

[0008] Preferably, a driven slider is rotatably connected to the top of the translation plate. The driven slider slides inside the limiting groove, and the limiting groove serves to drive the driven slider to move.

[0009] Preferably, the drive mechanism includes a support sleeve, which is fixedly installed on the top surface of the support gate, and the support sleeve provides a stable support effect for the use of the internal threaded gear.

[0010] Preferably, the support sleeve is rotatably connected to an internal threaded gear, and the lifting screw passes through the internal threaded gear and is threadedly connected to the internal threaded gear. The internal threaded gear drives the lifting screw to move up and down.

[0011] Preferably, a protective cover is fixedly connected to the outer surface of the support sleeve, and a drive gear is rotatably connected inside the protective cover. The drive gear meshes with an internal threaded gear, and the protective cover protects the drive gear.

[0012] Preferably, a servo motor is fixedly installed on the top surface of the supporting gate frame, and the drive gear is fixedly connected to the output shaft of the servo motor. The servo motor provides power for the raising and lowering of the water diversion gate.

[0013] This utility model provides a fall-proof irrigation canal water diversion gate, which has the following beneficial effects:

[0014] 1. This application incorporates components such as a water diversion gate, a limiting slide, a sliding plate, and a cleaning shovel. When the water diversion gate is closed, the limiting slide can move the sliding plate, which in turn moves the cleaning shovel to clear the area below the water diversion gate. This prevents stones and other debris from accumulating and hindering the gate's closure, ensuring a tight seal between the water diversion gate and the irrigation canal, improving the device's ability to separate irrigation water, reducing wear on the water diversion gate from stones, and extending the device's service life.

[0015] 2. This application, through the setting of components such as support sleeve, internal threaded gear, protective cover and drive gear, the rotation of drive gear drives internal threaded gear to rotate inside support sleeve. The rotation of internal threaded gear can drive lifting screw to rise and slide through thread groove, thereby driving water diversion gate to rise and fall. This allows the device to block or open irrigation channels as needed, facilitating the allocation of irrigation water resources and improving irrigation efficiency. Attached Figure Description

[0024] This utility model embodiment provides a water diversion gate for irrigation channels that prevents falls.

[0025] Please see Figure 1 and Figure 2 The system includes an irrigation canal 1, which is responsible for delivering water to farmland to meet the water needs of crop growth. It can play a role in allocating water resources, improving irrigation efficiency, and preventing floods and droughts. It is an important component of farmland water conservancy irrigation system. The structural diagrams of each component shown in the attached drawings of this application are all illustrative. The specific real-time method should be combined with the functional requirements, assembly conditions and process limitations in the actual application scenario, and the structural parameters, size specifications and connection methods should be adaptively adjusted and optimized.

[0026] A support gate frame 2 is fixedly connected to the top surface of the irrigation canal 1. A water diversion gate 3 is slidably connected inside the irrigation canal 1. The water diversion gate 3 is slidably connected to the support gate frame 2. The support gate frame 2 is used to support and limit the lifting and sliding of the water diversion gate 3, ensuring that the water diversion gate 3 can be lifted and lowered in the vertical direction. The inner wall of the irrigation canal 1 is provided with a slot that matches the water diversion gate 3. When the water diversion gate 3 is lowered into the slot, it can form a sealing effect, thereby blocking the irrigation water in the irrigation canal 1 and facilitating the allocation of irrigation water resources.

[0027] The top surface of the diversion gate 3 is rotatably connected to a lifting screw 4, and the top surface of the supporting gate frame 2 is provided with a drive mechanism 5 for driving the lifting screw 4. The drive mechanism 5 can drive the lifting screw 4 to rise and fall through the cooperation of the internal structure, thereby driving the diversion gate 3 to rise and fall, so as to realize the opening and closing of the gate. The lifting screw 4 has extremely high hardness and has better stability and durability than the traction devices such as winches or ropes mentioned in the background technology. It can effectively prevent the gate from falling and improve the safety and service life of the device.

[0028] Please see Figure 1 and Figure 4 The drive mechanism 5 includes a support sleeve 501, which is fixedly installed on the top surface of the support gate frame 2. An internal threaded gear 502 is rotatably connected inside the support sleeve 501. The lifting screw 4 passes through the internal threaded gear 502 and is threadedly connected to the internal threaded gear 502. The support sleeve 501 provides stable support and limiting effect for the internal threaded gear 502, so that the internal threaded gear 502 can remain stable during rotation. The internal threaded gear 502 has a threaded groove that matches the lifting screw 4. When the internal threaded gear 502 rotates, it can drive the lifting screw 4 to rise and fall through the threaded groove, thereby providing power for the opening and closing of the water diversion gate 3.

[0029] A protective cover 503 is fixedly connected to the outer surface of the support sleeve 501. A drive gear 504 is rotatably connected inside the protective cover 503. The drive gear 504 meshes with the internal thread gear 502. The support sleeve 501 and the protective cover 503 can provide a certain degree of protection for the rotation of the internal thread gear 502 and the drive gear 504, ensuring that the meshing relationship between the two is not disturbed, improving the transmission stability of the drive mechanism 5, and extending the service life of the device. Both the support sleeve 501 and the protective cover 503 are provided with openings, which will not obstruct the transmission of the internal thread gear 502 and the drive gear 504.

[0030] A servo motor 505 is fixedly installed on the top surface of the gate frame 2. The drive gear 504 is fixedly connected to the output shaft of the servo motor 505. The servo motor 505 is existing technology and will not be described in detail in this application. The output shaft of the servo motor 505 passes through the protective cover 503 and is rotatably connected to the protective cover 503. When the servo motor 505 is started, it can drive the drive gear 504 to rotate inside the protective cover 503. The rotation of the drive gear 504 can drive the internal thread gear 502 to rotate, thereby driving the diversion gate 3 to rise and fall.

[0031] Please see Figure 2 and Figure 3The outer surface of the diversion gate 3 is provided with a limiting groove 6. A translation plate 7 is slidably connected to the outer surface of the diversion gate 3. A driven slider 11 is rotatably connected to the top of the translation plate 7. The driven slider 11 slides inside the limiting groove 6. The limiting groove 6 is at a certain inclination angle. When the diversion gate 3 is raised or lowered, the driven slider 11 can be pulled to move through the limiting groove 6. The movement of the driven slider 11 can drive the translation plate 7 to move, thereby providing power for the cleaning shovel 8. The end of the driven slider 11 is provided with a limiting plate with a slightly larger diameter. The inside of the limiting groove 6 is provided with a corresponding limiting groove, which can ensure that the driven slider 11 slides stably inside the limiting groove 6 and improve the transmission stability of the device.

[0032] A cleaning shovel 8 is fixedly connected to the bottom of the sliding plate 7. The cleaning shovel 8 has a slope with a certain angle. The height of the slope is slightly higher than the height of the slot in the irrigation canal 1 used to seal with the diversion gate 3. When the diversion gate 3 descends, the driven slider 11 will drive the sliding plate 7 to move as the limit slide 6 descends. The movement of the sliding plate 7 can drive the cleaning shovel 8 to move inside the slot. The movement of the cleaning shovel 8 can clean the area directly below the diversion gate 3, shoveling the stones out of the slot through the slope. At this time, the stones and other debris will be washed away by the water flow, thereby preventing the debris from obstructing the seal between the diversion gate 3 and the irrigation canal 1.

[0033] The irrigation canal 1 has two fixed support slides 9 inside. The bottom wall of the irrigation canal 1 has a reserved groove. When the water diversion gate 3 descends to a certain position, the driven slider 11 slides to the highest position of the limit slide groove 6. At this time, the translation plate 7 will follow the water diversion gate 3 and descend under the drive of the driven slider 11, so that the cleaning shovel 8 can fall into the reserved groove, so as to avoid the cleaning shovel 8 affecting the sealing effect between the water diversion gate 3 and the irrigation canal 1. The end of the support slide 9 has a certain curvature to adapt to the descent of the translation plate 7.

[0034] Two limiting slide rods 10 are fixedly connected to the outer surface of the translation plate 7. The two limiting slide rods 10 slide inside the two support slides 9 respectively. The support slides 9 can limit and support the limiting slide rods 10, so that the translation plate 7 can stably maintain horizontal movement under the drive of the driven slider 11, and prevent the translation plate 7 from tilting and affecting the cleaning effect of the cleaning shovel plate 8.

[0035] Working principle: During use, when the operator wants to lower the diversion gate 3 to block the water flow, the servo motor 505 is activated. The servo motor 505 drives the drive gear 504 to rotate inside the protective cover 503. The rotation of the drive gear 504 drives the internal thread gear 502 to rotate inside the support sleeve 501. The rotation of the internal thread gear 502 drives the lifting screw 4 to descend through the threaded groove. The descent of the lifting screw 4 drives the diversion gate 3 to descend, thus providing conditions for water diversion operations. At the same time, the diversion gate 3 also drives the driven slider 11 to descend through the limit slide groove 6. Since the limiting slide 6 has a certain inclination angle, and the translation plate 7 can only move horizontally under the action of the supporting slide 9 and the limiting slide rod 10, when the diversion gate 3 descends, the translation plate 7 will drive the cleaning shovel 8 to move inside the slot. The movement of the cleaning shovel 8 can scoop out stones and other debris inside the slot through the inclined surface. The water flow will wash away the debris, thus preventing the debris from affecting the descent of the diversion gate 3. After the diversion gate 3 descends to a certain position, the cleaning shovel 8 will fall into the reserved groove to avoid obstructing the seal between the diversion gate 3 and the irrigation canal 1.
