Description

Technical Field

[0001] The present invention relates to the technical field of water gate detection, and in particular to a water gate closing force consistency detection device and a detection method. Background Art

[0002] A low-head hydraulic structure built on rivers and channels that uses gates to control flow and adjust water levels. The water-blocking principle of a sluice is achieved through a hydraulic system combined with the weight of the gate plate itself and the close fit between the gate plate and the gate frame. For example, a sluice proposed in a patent with application number CN201821382356.6 is mainly composed of components such as gate piers, gate frames and gate plates. When in use, a drain plate and a drain port are set on the gate plate. When the sluice is in a high water level difference, the drain plate is lifted to open the drain port to pre-drain the high water level difference water flow, so as to alleviate the impact of the water flow during discharge and avoid The water flow brings the silt from the upstream of the ditch into the sluice, causing the ditch to be blocked. After the existing sluice is produced, it is necessary to conduct multiple tests to ensure the quality and service life of the sluice. However, there are few tests on the closing force of the sluice gate. Since different sluices are used in different environments, the required closing force of the gate is also different. If the closing force of the gate does not meet the standard, it is easy to cause the water to continue to flow after the gate is closed, affecting the normal use of the sluice. If the closing force of the gate is too high, it is easy to damage the support seat and hydraulic system under the gate. Therefore, there is an urgent need for a sluice closing force consistency detection device and detection method. Summary of the invention

When the track trolley (3) moves, the hydraulic cylinder (4) stretches so that the top of the ball (6) squeezes the bottom of the track trolley (3) and the spring (5) contracts. Then the track trolley (3) continues to move. The elasticity of the spring (5) causes the ball (6) to extend into the limiting hole (22) of the track trolley (3). The power mechanism on the track trolley (3) stops running. The hydraulic cylinder (4) continues to extend so that the top of the hydraulic cylinder (4) extends into the limiting hole (22) of the track trolley (3) to limit the track trolley (3). Step 3: A group of sluice gates are closed so that the bottom end of the sluice gate is pressed down on the limit groove (8), and the force of closing the sluice gate is detected by the pressure sensor (9). Then the pressure sensor (9) transmits the detection data to the control computer, and then the sluice gate is reset, the track trolley (3) continues to move to the left, and step 2 is repeated to make the ball (6) extend into another group of limit holes (22), and the track trolley (3) is limited again, and the force of closing the other group of sluice gates is detected; Step 4: Repeat the above steps to complete the inspection of multiple groups or types of sluice gates on the supporting device; Step 5: Turn on the wear-resistant water pump (11), suck out the water in the detection box (7) through the circulation pipe (12), and then discharge the water into the mixing box (10) through the detection box (7), and make the water flow back to the detection box (7) through the connecting valve (13), and repeat the cycle to simulate the environment of river rapids. The track trolley (3) moves to the right on the two sets of tracks (2), and repeats steps 2 and 3 to test the closing force of the sluice in the river rapids environment; Step 6: Pour salt into the mixing box (10), drive the stirring shaft (15) through the reduction motor (14), so that the stirring shaft (15) mixes the salt and water, and repeat steps 2 and 3 to test the closing force of the sluice in the seawater environment; Step 7: drain the salt water in the detection box (7) and the mixing box (10), refill with water, pour the silt into the mixing box (10), drive the stirring shaft (15) through the reduction motor (14), so that the stirring shaft (15) mixes the silt and water, move to the right again on the two sets of tracks (2) through the track trolley (3), and repeat steps 2 and 3 to test the closing force of the sluice in the sandy river water environment; Step 8: The staff checks the test data through the control computer, and checks the consistency of the closing force of multiple groups of water gates of the same model, and the difference in the closing force of water gates of different models; Step nine: compress the air through the air compressor (18) and discharge the compressed air into the exhaust pipe (19), and discharge the compressed air into the detection box (7) through multiple sets of one-way valves (20), so that the mud and sand settled at the bottom of the detection box (7) float up, and at the same time open the drain valve (21) to discharge the water in the detection box (7).
