Description

Technical Field

[0001] This utility model relates to the field of dustproof net performance testing technology, and in particular to dustproof net performance testing equipment based on visual inspection technology. Background Technology

[0002] Dust control nets, also known as windbreak and dust suppression nets or windbreak and dust suppression walls, are mainly installed in places where dust pollution is prone to occur. They are used to reduce the effect of wind on carrying fine particulate matter. Performance testing can verify whether the dust control net can effectively reduce wind speed and wind pressure as required by the design.

[0003] In current dustproof net performance testing technology, the dustproof net is first fixed with two rectangular fixing plates, and its performance is evaluated by simulating wind force, wind speed and other relevant conditions in the actual use environment. However, when using existing technology for testing, the dustproof net is prone to detaching from the rectangular fixing plates due to excessive wind force, resulting in test failure. Furthermore, it is necessary to reset and reinstall the dustproof net and adjust the test conditions, which prolongs the test time and delays the test progress.

[0004] Therefore, there is a need for a dustproof net performance testing device based on visual inspection technology with anti-detachment function. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, such as dust nets easily detaching from rectangular fixing plates due to excessive wind force, leading to test failures and requiring reinstallation of the dust nets and adjustment of test conditions, which prolongs the testing time and delays the testing progress, this utility model provides a dust net performance testing device based on visual inspection technology with anti-detachment function.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a dustproof net performance testing device based on visual inspection technology, comprising a support base, mounting bracket, motor, first screw, moving block, fixed bracket, clamping plate, second screw, U-shaped bracket, and industrial camera. Two mounting brackets are fixedly connected to the support base. A motor is mounted on the mounting bracket, and a first screw is mounted on the motor's output shaft via a coupling. Two moving blocks are threaded onto the first screw, sliding on the support base. Fixed brackets are slidably mounted on the two corresponding moving blocks. A second screw is rotatably mounted on the fixed bracket, and a clamping plate is threaded onto the second screw, sliding on the fixed bracket. A U-shaped bracket is fixedly connected to the support bracket, and an industrial camera is mounted on the U-shaped bracket. The device also includes support blocks, reinforcing blocks, and elastic elements. Support blocks are symmetrically fixedly connected to the outer side of the clamping plate. A reinforcing block is slidably mounted between two support blocks on the same side, penetrating the clamping plate and contacting the fixed bracket. Elastic elements are fitted onto the support blocks, with both ends connected to the support blocks and the reinforcing blocks, respectively.

[0007] More preferably, it also includes a support frame, a rotating shaft, and a nozzle. Two support frames are mounted on the support base, a rotating shaft is rotatably mounted on the support frame, and a nozzle is mounted on the rotating shaft.

[0008] More preferably, it also includes a cylinder and a connecting rod, wherein the cylinder is mounted on two moving blocks, the connecting rod is mounted on the telescopic rod of the cylinder, and the connecting rod is fixedly connected to a nearby fixed frame.

[0009] More preferably, it also includes a storage frame, which is slidably installed inside the support base.

[0010] More preferably, the U-shaped bracket has two guide grooves, in which the industrial camera slides.

[0011] More preferably, the edges of the reinforcing block have an arc-shaped structure.

[0012] More preferably, a limit block is fixedly connected to the second screw.

[0013] More preferably, the mounting bracket has a slot.

[0014] Compared with the prior art, the present invention has the following technical effects: 1. By pulling the reinforcing block upward and reversing the second screw to drive the clamp plate on it to move downward, the dustproof net is initially fixed. Then, the reinforcing block is released, and the elastic element drives the reinforcing block to move downward, thereby inserting the dustproof net into the slot in the fixing frame, thus achieving secondary fixation. This prevents the dustproof net from detaching from the fixing component due to testing factors during testing.

[0015] 2. By rotating the nozzle to a suitable angle with the shaft, and then connecting the external water pipe to the nozzle, water is sprayed from the nozzle onto the dustproof net. This allows you to test the waterproof performance and water impact resistance of the dustproof net.

[0016] 3. By sprinkling sand onto the dustproof net and activating two cylinders, the extension and retraction of the cylinder rods drive the connecting rod, moving block, fixed frame and its components, as well as the dustproof net, to move back and forth. This ensures that the sand on the dustproof net is evenly distributed, guaranteeing the accuracy of the test. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Dustproof net performance testing equipment based on visual inspection technology, see [link / reference] Figures 1-3 and Figure 5 As shown, the system includes a support base 1, a mounting bracket 2, a motor 201, a first screw 202, a movable block 3, a fixed bracket 4, a clamping plate 5, a second screw 6, a U-shaped bracket 10, and an industrial camera 11. The mounting bracket 2 is fixedly connected to both the front and rear sides of the upper part of the support base 1. The motor 201 is bolted to the right side of the mounting bracket 2. The first screw 202 is mounted on the output shaft of the motor 201 via a coupling. Both ends of the first screw 202 are threaded, and movable blocks 3 are threaded onto both ends of the first screw 202. The movable blocks 3 slide on the support base 1. Fixed brackets 4 are slidably mounted on two corresponding movable blocks 3. A second screw 6 is rotatably mounted on the rear of the fixed frame 4, which is positioned above the support base 1. A clamping plate 5 is threaded onto the second screw 6 and slides on the fixed frame 4. A U-shaped bracket 10 is welded to the upper part of the support frame 12. An industrial camera 11 is mounted on the U-shaped bracket 10. The support frame 12 also includes a support block 7, a reinforcing block 8, and an elastic element 9. The support blocks 7 are symmetrically fixed to the outer side of the clamping plate 5. A reinforcing block 8 is slidably mounted between two support blocks 7 located on the same side. The reinforcing block 8 passes through the clamping plate 5 and contacts the fixed frame 4. An elastic element 9 is fitted onto the support block 7, and the two ends of the elastic element 9 are connected to the support block 7 and the reinforcing block 8, respectively.

[0025] See Figure 2 As shown, the U-shaped bracket 10 has two guide grooves 18, and the industrial camera 11 slides in the two guide grooves 18, so as to move the industrial camera 11 and ensure detection accuracy.

[0026] See Figure 3 As shown, the lower part of the reinforcing block 8 has an arc-shaped structure 19 to prevent indentations on the dustproof net.

[0027] See Figure 3 As shown, a limit block is fixedly connected to the top of the second screw 6 to prevent the clamp 5 from detaching.

[0028] See Figure 5 As shown, the fixing frame 4 has a slot, which allows the reinforcing block 8 to press the dustproof net into the slot and prevent it from moving.

[0029] When the dustproof net needs to be inspected, first start both motors 201. The output shaft of motor 201 drives the first screw 202 to rotate, causing the two moving blocks 3 on it to move, and moving the fixed frame 4 to the appropriate position. After moving to the appropriate position, turn off motor 201, and then rotate the second screw 6 to move the clamping plate 5 on it upward. As the clamping plate 5 moves, it also moves the support block 7, reinforcing block 8, and elastic element 9 on it. Then place the dustproof net between the two clamping plates 5 and the two fixed frames 4, and then pull it upward. The reinforcing block 8 reverses the second screw 6, causing the clamping plate 5 on it to move downwards. The elastic element 9 is stretched accordingly, thus initially fixing the dustproof net. Then the reinforcing block 8 is released, and the elastic element 9 causes the reinforcing block 8 to move downwards, thereby locking the dustproof net into the slot in the fixing frame 4. This is a secondary fixation, which can prevent the dustproof net from detaching from the fixing parts due to testing factors during the test. After the fixation is completed, environmental simulation is performed to test the dustproof net. At the same time, the moving industrial camera 11 records the test process and calculates the test data in combination with computer software.

[0030] Example 2: Based on Example 1, refer to Figure 1 and Figure 4 As shown, it also includes a support frame 12, a rotating shaft 13 and a nozzle 14. The support frame 12 is symmetrically installed on the right side of the support base 1. The rotating shaft 13 is rotatably installed on the upper part of the support frame 12, and the nozzle 14 is installed on the rotating shaft 13.

[0031] In a simulated environment, the nozzle 14 is rotated to a suitable angle with the shaft 13, and then the external water pipe is connected to the nozzle 14 so that water is sprayed from the nozzle 14 onto the dustproof net. This allows the waterproof performance and water impact resistance of the dustproof net to be tested. After the test is completed, the external water pipe is removed and the next test can be performed.

[0032] See Figure 5As shown, it also includes a cylinder 15 and a connecting rod 16. The cylinder 15 is bolted to the front of the two moving blocks 3. The connecting rod 16 is installed on the telescopic rod of the cylinder 15 and is fixedly connected to the nearby fixed frame 4.

[0033] See Figure 1 As shown, it also includes a storage frame 17, which is slidably installed inside the support base 1.

[0034] When conducting a sand-proof test, sand is sprinkled onto the dustproof net, and two cylinders 15 are activated. The extension and retraction of the telescopic rods of cylinders 15 drive the connecting rod 16, the moving block 3, the fixed frame 4 and its components, as well as the dustproof net, to move back and forth. This ensures that the sand on the dustproof net is evenly distributed, guaranteeing the accuracy of the test. The filtered sand falls into the collection frame 17 for easy cleaning.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
