Description

Technical Field

[0001] This invention relates to the technical field of arc gate detection, and in particular to a gap detector for arc gates and its usage method. Background Technology

[0002] Gates are control facilities used to close and open water discharge channels. Gates undergo multiple tests before leaving the factory, but the bottom gap of curved gates is rarely tested. After the gate is closed, a gap can easily appear between the bottom of a substandard gate and the base, causing leakage. There are various reasons for this gap, such as gate bottom tilting, gate installation tilting, impurities at the bottom of the gate, and insufficient pressure in the pressure system driving the gate. Existing gate gap detection equipment, such as the gate gap detection device proposed in patent application number CN202121951653.X, mainly consists of a gate gap detection device. During use, it can measure the extension and retraction displacement of the elastic push rod in real time through a displacement detection unit to obtain the gate gap data. The measured gate gap data includes the civil engineering error of the gate wall, and the measured data is real-time and accurate. However, it is inconvenient to test gates after production and it is difficult to detect the cause of the gap, resulting in poor practicality. Therefore, there is an urgent need for a gap detector for curved gates and its usage method. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a gap detector for an arc gate and its usage method, which involves installing multiple sets of arc gates on a mobile device, draining water into a support mechanism, adding sand or gravel to different detection sections, adjusting the position of the multiple sets of arc gates by the mobile device, closing the multiple sets of arc gates sequentially, and detecting the gaps of the arc gates by a detection device, thereby improving the practicality of the equipment.

[0004] The present invention provides a gap detector for an arc-shaped gate, comprising a support mechanism, a moving device, and a detection device, wherein the moving device is mounted on the support mechanism and the detection device is mounted in the support mechanism.

[0005] The support mechanism transports the water flow, the moving device adjusts the position of the arc-shaped gate, and the detection device detects the gap after the arc-shaped gate is closed.

[0006] Multiple sets of arc-shaped gates are installed on a mobile device, water is discharged into the support mechanism, and sand or gravel is added to different detection sections. Then, the position of the multiple sets of arc-shaped gates is adjusted by the mobile device, and the multiple sets of arc-shaped gates are closed in sequence. The gap of the arc-shaped gates is detected by the detection device, thereby improving the practicality of the equipment.

[0007] Preferably, the support mechanism includes a water tank, two sets of guide rails, two sets of sliders, and a frame. The bottom ends of the two sets of guide rails are connected to the top of the water tank. The two sets of sliders are slidably mounted on the two sets of guide rails. The bottom end of the frame is connected to the top of the two sets of sliders, and multiple hydraulic systems are installed on the frame. Water is discharged into the water tank, causing it to flow from left to right. Multiple gates are installed on multiple hydraulic systems, and then the gates are closed by the hydraulic systems. The gaps between the gates are detected, thereby improving the practicality of the equipment.

[0008] Preferably, the water tank includes a detection tank, a storage tank, two sets of conveying pipes, two sets of drive motors, two sets of rotary conveying shafts, and a circulation device. The top of the detection tank is connected to the bottom of the two sets of guide rails, and the right end of the storage tank is connected to the left end of the detection tank. The detection tank and the storage tank are internally connected. Both sets of conveying pipes are installed inside the detection tank, and each set of conveying pipes has an inlet at its top and multiple outlets at its bottom. The two sets of drive motors are respectively installed at the front ends of the two sets of conveying pipes. The front ends of the two sets of rotary conveying shafts are respectively connected to the rear ends of the two sets of drive motors, and the rear ends of the two sets of rotary conveying shafts extend into the two sets of conveying pipes. The circulation device is installed at the bottom of the detection tank. Water is discharged into the storage tank, allowing water to flow into the detection tank. Then, a moving device adjusts the position of multiple sets of gates, causing the multiple sets of gates to close sequentially on the left side of the detection tank. The gap between the gates is detected by the detection device, and the operator observes the flow of water inside the detection tank. The system first checks the gate gaps, then moves the device to adjust the positions of multiple gates, causing them to close sequentially in the middle of the testing box. Simultaneously, sand is placed into the left-side conveyor pipe, and the drive motor is turned on. The rotating conveyor shaft then discharges the sand into the water within the testing box, where it flows with the water. The gate gaps are checked by the detection device, and staff observe the water flow within the testing box to assess the gate gaps and the hydraulic system's condition. The system then moves the device again to adjust the positions of multiple gates, causing them to close sequentially on the right side of the testing box. Gravel is then placed into the right-side conveyor pipe, and the drive motor is turned on. The rotating conveyor shaft then discharges the gravel into the water within the testing box, where it flows with the water. The gate gaps are checked by the detection device, and staff observe the water flow within the testing box to assess the gate gaps and the hydraulic system's condition, thus improving the equipment's practicality.

[0009] Preferably, the circulation device includes a filter box, a circulation pipe, multiple sets of filter plates, and a circulation pump. The top of the filter box is connected to the bottom of the test box. One end of the circulation pipe communicates with the interior of the test box, and the other end of the circulation pipe communicates with the interior of the filter box. Multiple sets of filter plates are installed inside the filter box. The circulation pump is installed between the storage tank and the filter box, and the suction port of the circulation pump communicates with the interior of the filter box, while the discharge port of the circulation pump communicates with the interior of the storage tank. Water, sand, and pebbles in the test box are discharged into the filter box through the circulation pipe. The multiple sets of filter plates perform graded filtration of the water, sand, and pebbles. At the same time, the circulation pump is turned on to discharge the water in the filter box into the storage tank for water recycling. Afterward, the filter box is opened to remove the sand and pebbles for recycling, thereby improving the practicality of the equipment.

[0010] Preferably, the moving device includes two sets of reduction motors, two sets of first gears, and two sets of locking devices. Each of the two sets of sliders has several gear teeth, and each set of sliders has multiple sets of limiting grooves at its bottom. The two sets of reduction motors are respectively installed at the front and rear ends of the water tank. The two sets of first gears are respectively installed on the output shafts of the two sets of reduction motors, and the tops of the two sets of first gears mesh with the gear teeth on the two sets of sliders. The two sets of locking devices are respectively installed at the front and rear ends of the water tank. When the two sets of reduction motors are turned on, the two sets of first gears mesh with the gear teeth of the two sets of sliders, driving the two sets of sliders to slide on the two sets of guide rails, adjusting the positions of multiple gates. Then, the locking devices limit the position of the sliders, thereby improving the practicality of the equipment.

[0011] Preferably, the locking device includes a hydraulic cylinder, a limiting block, and a limiting frame. The hydraulic cylinder and the limiting frame are both mounted on the detection box. The bottom end of the limiting block is connected to the top end of the hydraulic cylinder, and the top end of the limiting block passes through the limiting frame. By extending the hydraulic cylinder, the limiting frame extends into the limiting groove at the bottom end of the slider to limit the slider, thereby improving the practicality of the equipment.

[0012] Preferably, the detection device includes multiple sets of bases, multiple sets of springs, multiple sets of racks, multiple sets of buffer plates, multiple sets of second gears, and multiple sets of Hall sensors. The bottom ends of the multiple sets of bases are all connected to the bottom end of the detection box, and the interior of each set of bases is provided with multiple chambers. The bottom ends of the multiple sets of springs are respectively installed in the multiple chambers of the multiple sets of bases. The bottom ends of the multiple sets of racks are respectively connected to the top ends of the multiple sets of springs. The bottom ends of the multiple sets of buffer plates are respectively connected to the top ends of the multiple sets of racks. The multiple sets of second gears are rotatably installed in the multiple chambers of the multiple sets of bases. The multiple sets of Hall sensors are respectively fixedly installed in the multiple chambers of the multiple sets of bases. After the gate is closed, the bottom end of the gate presses down on the top end of the base, causing the multiple sets of springs to retract into the base. At the same time, the racks descend and drive the second gears to rotate, allowing the Hall sensors to detect the number of rotations of the second gears. The Hall sensors transmit the detection results to the control computer, allowing the operator to determine the position and condition of the gate gap. Afterward, when the gate is raised, the spring elasticity causes the buffer plates to reset, thereby improving the practicality of the equipment.

[0013] The present invention provides a method for using a gap detector for an arc-shaped gate, comprising the following steps:

[0014] Step 1: Install multiple sets of gates onto multiple sets of hydraulic systems, and drain water into the storage tank, allowing the water to flow into the interior of the detection box to simulate a river state;

[0015] Step 2: Turn on the two sets of reduction motors, and drive the two sets of sliders to slide on the two sets of guide rails through the meshing of the first gears of the two sets of first gears respectively. Adjust the position of the multiple gates, and then limit the position of the sliders through the locking device.

[0016] Step 3: Multiple sets of hydraulic systems are then used to drive the closure of multiple gates sequentially on the left side of the testing box. The gaps between the gates are detected by a detection device, while personnel observe the water flow within the testing box to assess the gate gaps. The moving device then repositions the gates, causing them to close sequentially in the middle of the testing box. Simultaneously, sand is placed into the left-side conveyor pipe, and the drive motor is turned on. The rotating conveyor shaft then discharges the sand into the water within the testing box, where it flows with the water. The detection device monitors the gaps between the gates. The gap is detected, and the staff observes the water flow in the detection box to determine the gate gap and the condition of the hydraulic system. Then, the moving device readjusts the position of multiple gates so that they close sequentially on the right side of the detection box. At the same time, stones are put into the right-side conveying pipe, the drive motor is turned on, and the rotating conveying shaft drives the stones into the water in the detection box. The stones flow with the water, and the gate gap is detected by the detection device. Meanwhile, the staff observes the water flow in the detection box to determine the gate gap and the condition of the hydraulic system.

[0017] Step 4: During the testing process, after the gate is closed, the bottom of the gate presses down on the top of the base, causing multiple sets of springs to retract into the base. At the same time, the rack descends and drives the second gear to rotate, allowing the Hall sensor to detect the number of rotations of the second gear. The Hall sensor then transmits the detection results to the control computer, enabling the staff to determine the position and condition of the gate gap. After the gate is lifted, the spring elasticity causes the buffer plate to reset.

[0018] Step 5: Drain the water, sand, and pebbles from the test chamber into the filter chamber through the circulation pipe. The water, sand, and pebbles are filtered in stages by multiple sets of filter plates. At the same time, turn on the circulation pump to drain the water in the filter chamber into the storage tank for water recycling. After that, open the filter chamber and take out the sand and pebbles for recycling.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. Test multiple gates in sequence, and find out the cause of the gate gap by adding different sand and gravel;

[0021] 2. When recycling water, sand and gravel should also be recycled and reused.

[0022] 3. Position the gate to improve the accuracy and stability of gate closure. Attached Figure Description
