Technical Field

[0001] This invention relates to the field of wind resistance simulation testing technology, specifically to a mobile cooling tower wind resistance testing device. Background Technology

[0002] With the development of the times, the capacity of generator sets has gradually increased, and a number of large cooling towers with a height of over 190m have emerged. At this time, it is necessary to test the wind resistance of the produced cooling towers.

[0003] A testing device for the wind displacement strength of a mechanical ventilation cooling tower, based on existing technology on the market, includes: a tilt test base, a wind-resistant frame, a tilt monitoring mechanism, and an anemometer. The tilt test base is located directly below the tilt monitoring mechanism and is fixed on the same plane as the wind-resistant frame. The tilt monitoring mechanism includes a deflection rod, a measuring rod, and a clamping assembly. One end of the deflection rod is fixed to the top of the wind-resistant frame, and a deflection seat rod is movably connected to the end of the deflection rod.

[0017] In summary, the present invention has the following main beneficial effects:

[0018] 1. The device is structurally designed so that the upper inclined plate can tilt at an angle through the hinge between the upper and lower connecting rods.

Then, align the moving block body on the outer wall of the base with the fixing groove on the fixed block body and bring them into contact, so that the upper inclined plate is retracted into the testing column body. Afterwards, the staff uses a forklift to transport the moving base into the wind tunnel. The staff manually rotates the circular moving block, so that the anemometer body detects the wind speed behind the mold. Based on the wind force difference generated in the wind tunnel, the staff judges the magnitude of the wind field force generated by the wind tunnel. When the cooling tower model tilts under the action of the wind, the upper inclined plate tilts accordingly. At this time, the upper connecting rod rotates under the support of the lower connecting rod. The four optical height gauges detect the lowest position of the upper inclined plate and send the data to the external control panel. The main board in the control panel calculates the result.

[0020] 3. At the same time, the device has a fixed structure, which allows the detection column body to be better fixed on the moving base through the displacement sleeve, and at the same time, it is convenient for the staff to disassemble it. Attached Figure Description

[0037] Two optical height gauges 221 are symmetrically embedded in the inner wall of the cavity 210. The optical height gauges 221 adopt the existing technology structure and are used to detect the tilt angle of the upper tilt plate 241.

[0039] When it is necessary to conduct wind resistance tests on cooling towers:

[0040] S1: Place the proportionally scaled-down mold on the moving plate of the detection device 200, and then the upper chuck 252 clamps it to keep the mold at the center of the upper inclined plate 241.

[0041] S2: The staff uses tools to lift the lower base 281 and aligns the moving block body 282 with the fixing groove 234 opened on the fixed block body 233. Then, the staff uses an external control panel to retract the output end of the displacement hydraulic rod 232. After that, the staff uses a forklift to transport the moving base 100 into the wind tunnel.

[0042] S3: The output end of the return hydraulic rod 271 moves down. At the same time, the staff manually rotates the circular moving block 213. The circular moving block 213 rotates in the circular slide 212, so that the anemometer body 215 detects the wind speed behind the mold and judges the magnitude of the wind field force on the wind generated by the wind tunnel based on the wind force difference generated by the wind tunnel.

[0043] S4: When the cooling tower model tilts under the action of wind, the upper tilting plate 241 tilts accordingly, and the upper connecting rod 261 rotates under the support of the lower connecting rod 262.

[0044] S5: Four optical altimeters 221 detect the lowest position of the upper inclined plate 241 and send the data to the external control panel;

[0045] S6: The mainboard within the control panel performs calculations to arrive at a conclusion;

[0046] S7: After the test is completed, the return hydraulic rod 271 starts to work, its output end extends, and it lifts the inclined upper tilting plate 241 to a flat position. Finally, it can be transported away by a forklift.

[0047] The device has a neat overall shape, which facilitates transportation and effectively reduces transportation costs. At the same time, its high degree of automation makes it easy to clamp and inspect molds, effectively reducing the labor intensity of users.

[0048] Please refer to Figure 1 , Figure 2 and Figure 5An movable groove 242 is provided at the center of the upper surface of the upper inclined plate 241. A movable plate body 243 is provided on the upper surface of the bottom plate of the movable groove 242. The outer wall of the movable plate body 243 is in contact with the inner wall of the movable groove 242 and is movably connected. Four upper clamps 252 are provided on the side of the upper inclined plate 241 near the movable groove 242.

[0049] The upper surface of the inclined plate 241 is provided with displacement grooves 251 at the positions that match the four upper chucks 252. The lower surface of each of the four upper chucks 252 is provided with a connecting rod body 253. The four upper chucks 252 are provided with a central fixing block 254 facing each other. Two clamping hydraulic rods 255 are symmetrically arranged on the outer wall of the central fixing block 254. The side of the four clamping hydraulic rods 255 away from the output end is in contact with the outer wall of the central fixing block 254.

[0050] The four clamping hydraulic rods 255 are connected to the outer wall of the central fixing block 254 by a bracket on the side away from the output end. The output ends of the four clamping hydraulic rods 255 are in contact with the outer wall of the connecting rod body 253 on one side.

The inner walls of the four displacement grooves 251 are in contact with the outer wall of the clamping hydraulic rods 255.

[0051] When it is necessary to clamp the mold:

[0052] S1: The staff holds the mold with both hands and places the mold as close as possible to the center of the movable plate 243. At this time, the return hydraulic rod 271 is in the extended state.

[0053] S2: The operator controls the external control panel to start the clamping hydraulic rod 255 to work;

[0054] S3: The clamping hydraulic rod 255 starts to work, its output end extends, and squeezes the movable plate 243, so that the movable plate 243 moves in the movable groove 242;

[0055] S4: During the period, the return hydraulic rod 271 moves down intermittently. When the mold is not in the center, the upper tilting plate 241 tilts. The tilting state is detected by the optical height measuring instrument 221. The output end of the return hydraulic rod 271 extends and the clamping hydraulic rod 255 is adjusted until the center of the mold and the center of the upper connecting rod 261 are vertically overlapped.

[0056] S5: The output end of the return hydraulic rod 271 moves upward to support the upper inclined plate 241 until the test begins, at which point the output end of the return hydraulic rod 271 moves downward.

[0057] The device, through its internal structure, can keep the mold in a centered position by repeated testing and adjustment, reducing errors during testing and effectively reducing the labor intensity of workers. Furthermore, the detachable design of the internal inclined plate 241 and other structures allows for continuous testing while ensuring accuracy and effectively improving testing efficiency.

[0058] Please refer to Figure 1 and Figure 7 The fixing structure 300 includes a fixing strip 311 located at the center of the lower surface of the detection column body 211. The upper surface of the fixing strip 311 is in contact with the lower surface of the detection column body 211 and is bolted together. Fixing slots 312 are symmetrically opened on the outer walls of both sides of the fixing strip 311. The upper surface of the movable base 100 is provided with a strip groove 321. The inner wall of the strip groove 321 is in contact with the outer wall of the fixing strip 311 and the two match. Through holes 322 are opened on both sides of the inner wall of the strip groove 321. Fixing plates 331 are provided inside the two through holes 322.

[0059] Both outer walls of the two fixed plates 331 are in contact with and fixedly connected to the inner wall of the through hole 322. Each of the two fixed plates 331 has a sliding rod body 332 on the opposite side. The outer wall of the opposite end of the two sliding rod bodies 332 is in contact with and fixedly connected to the outer wall of one side of the fixed plate 331. Each of the two sliding rod bodies 332 has a sleeve 334 on the opposite side. The outer walls of both slide rod bodies 332 are in contact with the inner wall of sleeve 334 and are connected by snap fasteners. The outer walls of both slide rod bodies 332 are provided with slide rod springs 333. The outer walls of both slide rod springs 333 are in contact with the outer wall of one side of the fixed plate 331, the outer wall of the slide rod body 332, and the outer wall of one end of the sleeve 334. The outer walls of both sleeves 334 away from each other are symmetrically provided with pull plates 335. One end of each pull plate 335 is in contact with one end of the outer wall of the sleeve 334 and is connected by a bracket. The ends of the four pull plates 335 away from the sleeves 334 are fixedly connected with pull rings 336.

[0060] The outer walls of the four pull rings 336 are in contact with the inner wall of the through hole 322. The inner diameter of the through hole 322 is smaller than the diameter of the pull rings 336. The outer walls of the two sleeves 334 are in contact with the inner wall of the fixing slot 312 and are movably connected.

[0061] When it is necessary to remove the detection device 200 from the movable base 100:

[0062] S1: First, the staff uses external tools to fix the detection device (200) on the crane. Then, the staff pulls the pull ring 336 with both hands and exerts force in a direction away from the detection column body 211.

[0063] S2: The pull ring 336 transmits force to the sleeve 334 through the pull plate 335, causing the sleeve 334 to move on the slide bar body 332. At this time, the slide bar spring 333 is in a compressed state.

[0064] S3: As the force applied by the worker moves, the sleeve 334 gradually moves away from the fixing slot 312. At this point, the worker can lift the detection device 200. When the worker's force disappears or decreases, the slide spring 333 releases its force, pushing the sleeve 334 into the fixing slot 312 to complete the fixing of the detection device 200.

[0065] This device can quickly fix the detection device 200, making it convenient for staff to use.

[0066] The working principle of this invention is as follows:

[0067] When it is necessary to conduct wind resistance tests on cooling towers:

[0068] S1: The staff holds the mold with both hands and places the mold as close as possible to the center of the movable plate 243. At this time, the return hydraulic rod 271 is in the extended state.

[0069] S2: The operator controls the external control panel to start the clamping hydraulic rod 255 to work;

[0070] S3: The clamping hydraulic rod 255 starts to work, its output end extends, and squeezes the movable plate 243, so that the movable plate 243 moves in the movable groove 242;

[0071] S4: During the period, the return hydraulic rod 271 moves down intermittently. When the mold is not in the center, the upper tilting plate 241 tilts. The tilting state is detected by the optical height measuring instrument 221. The output end of the return hydraulic rod 271 extends and the clamping hydraulic rod 255 is adjusted until the center of the mold and the center of the upper connecting rod 261 are vertically overlapped.

[0072] S5: The staff uses tools to lift the lower base 281 and aligns the moving block body 282 with the fixing groove 234 opened on the fixed block body 233. Then, the staff uses an external control panel to retract the output end of the displacement hydraulic rod 232. After that, the staff uses a forklift to transport the moving base 100 into the wind tunnel.

[0073] S6: The output end of the return hydraulic rod 271 moves down. At the same time, the staff manually rotates the circular moving block 213. The circular moving block 213 rotates in the circular slide 212, so that the anemometer body 215 detects the wind speed behind the mold and judges the magnitude of the wind field force on the wind generated by the wind tunnel based on the wind force difference generated by the wind tunnel.

[0074] S7: When the cooling tower model tilts under the action of wind, the upper tilting plate 241 tilts accordingly, and the upper connecting rod 261 rotates under the support of the lower connecting rod 262.

[0075] S8: Four optical altimeters 221 detect the lowest position of the upper inclined plate 241 and send the data to the external control panel;

[0076] S9: The main board in the control panel calculates and draws a conclusion. After the test is completed, the return hydraulic rod 271 starts to work. Its output end extends to lift the inclined upper tilting plate 241 to a flat position. Finally, it can be transported away by a forklift.

[0077] When it is necessary to remove the detection device 200 from the movable base 100:

[0078] S1: First, the staff uses external tools to fix the detection device (20Q) on the crane. Then, the staff pulls the pull ring 336 with both hands and exerts force in a direction away from the detection column body 211.

[0079] S2: The pull ring 336 transmits force to the sleeve 334 through the pull plate 335, causing the sleeve 334 to move on the slide bar body 332. At this time, the slide bar spring 333 is in a compressed state.

[0080] S3: As the force applied by the worker moves, the sleeve 334 gradually moves away from the fixing slot 312. At this point, the worker can lift the detection device 200. When the worker's force disappears or decreases, the slide spring 333 releases its force, pushing the sleeve 334 into the fixing slot 312 to complete the fixing of the detection device 200.
