[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] Example 1: Figures 1 to 6 As shown, a wind turbine blade mountain transport protection device according to an embodiment of the present invention includes a mounting base 1 and a circulation box 7. The mounting base 1 is provided with a rotatable mounting platform 2, and the mounting platform 2 is provided with a holder 3 for fixing the wind turbine blade; the mounting base 1 is provided with a hydraulic rod 4, and the hydraulic rod 4 is used to push the mounting platform 2 to rotate. The hydraulic rod 4 is sleeved with a connecting sleeve 5, and a circulation pipe 6 is provided in the connecting sleeve 5; one side of the circulation box 7 is connected to a water outlet pipe 9 and a water inlet pipe 8, and the water outlet pipe 9 and the water inlet pipe 8 are connected to the circulation pipe 6. Coolant is provided in the circulation box 7, a circulation pump is provided in the circulation box 7, and a thermostat 10 for keeping the coolant at a constant temperature is provided on the circulation box 7; The present application can install the mounting base 1 on a mountain transport vehicle, and then fix the wind turbine blades on the holder 3. In order to ensure the safety of transporting blades in the mountains, the angle of the mounting platform 2 can be adjusted by the hydraulic rod 4 to allow the blades to rotate. Before the hydraulic rod 4 works, the circulating pump drives the coolant to flow in the circulating pipe 6. At this time, the coolant will keep the hydraulic oil in the hydraulic rod 4 at a constant temperature, thereby ensuring the stability of the hydraulic rod 4, so as to improve the accuracy of adjusting the wind turbine blades. After the blades are rotated to the appropriate angle, they can avoid contact with obstacles such as mountains, trees, and rocks.
[0023] The inner wall of the circulation box 7 near the water inlet pipe 8 is fixedly connected to a mounting frame 11, the inner wall of the mounting frame 11 is fixedly connected to a connecting frame 12 arranged obliquely, the inner wall of the connecting frame 12 is fixedly connected to a filter screen 13, a discharge groove is provided on the side wall of the circulation box 7 near the filter screen 13, a discharge groove 15 connected to the discharge groove is provided in the mounting frame 11, the bottom surface of the discharge groove 15 is inclined, and the discharge groove 15 and the connecting frame 12 extend to the inner wall of the mounting frame 11, and a sealing component for sealing the discharge groove is provided in the circulation box 7; Since trace metal particles, sediments of incompletely dissolved additives or synthetic by-products may remain during the coolant manufacturing process, dirt and old liquid residues in tools or containers may introduce impurities when replacing the coolant or repairing it. These impurities will reduce the cooling efficiency. At this time, when the coolant is circulating, the coolant will pass through the filter 13, so that the impurities in the coolant are captured by the filter 13 to prevent the impurities from affecting the use effect of the coolant. When the coolant is working, the captured impurities will adhere to the filter 13 due to the flowing liquid. When the coolant stops circulating, the captured impurities can slide from the inclined filter 13 to the discharge trough 15 for temporary storage to prevent the impurities from clogging the filter 13 and affecting the use of the filter 13. When the impurities need to be discharged, the sealing component can no longer seal the discharge trough, and the impurities can be discharged from the discharge trough.
[0024] The sealing assembly includes a slide 14 opened on the circulation box 7, the slide 14 is connected to the discharge trough, and a first sealing plate 16 is arranged inside the slide 14, and a first spring is fixedly connected between the bottom surface of the first sealing plate 16 and the inner wall of the slide 14, and the first sealing plate 16 is fixedly connected to a round rod on the side away from the mounting frame 11; when impurities need to be discharged, the round rod can be manually pushed downward so that the round rod drives the first sealing plate 16 to no longer seal the discharge trough. At this time, the impurities in the discharge trough 15 can be discharged mixed with the coolant. After the impurities are discharged, the round rod is released, and the first spring will push the first sealing plate 16 to seal the discharge trough.
[0025] The mounting frame 11 is provided with a moving groove 17, and a second sealing plate 18 is slidingly connected in the moving groove 17. A second spring is fixedly connected between the side of the second sealing plate 18 close to the first sealing plate 16 and the inner wall of the moving groove 17. A connecting groove 19 is provided on the second sealing plate 18, and the first sealing plate 16 is sealingly and slidingly connected to the inner wall of the slide groove 14. A connecting pipe 20 is connected between the slide groove 14 and the moving groove 17; in the present application, when the first sealing plate 16 moves downward, it pushes the gas in the slide groove 14 from the connecting pipe 20 into the moving groove 17. At this time, the gas pushes the second sealing plate 18, so that the connecting groove 19 on the second sealing plate 18 enters the moving groove 17. At this time, the second sealing plate 18 can seal the discharge end of the discharging chute 15 to prevent more coolant from being discharged when impurities are discharged. When the first sealing plate 16 moves upward, the second sealing plate 18 will be reset under the pull of the second spring. At this time, impurities can enter the discharging chute 15 through the connecting groove 19 for storage.
[0026] A rotating shaft 21 is provided in the circulation box 7, and a plurality of driving blades 22 are fixedly connected to the surface of the rotating shaft 21; when the coolant in the present application circulates, the water flow will drive the driving blades 22 to rotate, and at this time the driving blades 22 will stir the circulation box 7, so that the thermostat 10 can speed up the rate of keeping the coolant at a constant temperature when keeping the coolant at a constant temperature in the circulation box 7.
[0027] The interior of the rotating shaft 21 is a hollow structure, and the inner wall of the rotating shaft 21 is sealed and slidably connected to the piston 24. A moving component for driving the piston 24 to move is provided in the rotating shaft 21, and the side wall of the rotating shaft 21 is provided with multiple groups of through grooves 23 connected to the interior thereof; in the present application, when the rotating shaft 21 rotates, the moving component can be used to drive the piston 24 to move up and down. When the piston 24 moves upward, the through groove 23 will suck the coolant into the rotating shaft 21, and when the piston 24 moves downward, the coolant will be ejected from the through groove 23, thereby improving the fluidity of the coolant in the circulation box 7, so as to further improve the efficiency of the coolant constant temperature.
[0028] The moving component includes an annular groove 27 provided on the top surface of the inner wall of the rotating shaft 21, and the top surface of the piston 24 is fixedly connected to a connecting rod 25 extending into the annular groove 27. The connecting rod 25 is made of magnetic material, and the top surface of the inner wall of the circulation box 7 is fixedly connected to a first magnetic block 26 that is magnetically attracted to the connecting rod 25. A third spring is fixedly connected between the top surface of the piston 24 and the inner wall of the rotating shaft 21; in this application, when the rotating shaft 21 rotates, the connecting rod 25 will pass through the first magnetic block 26, and at this time the connecting rod 25 will be attracted by the first magnetic block 26 to move upward, thereby achieving the upward movement of the piston 24. When the connecting rod 25 is away from the first magnetic block 26, the third spring will push the piston 24 to move downward, so that during the rotation of the rotating shaft 21, the piston 24 can continue to move up and down.
[0029] The side of the filter 13 away from the water inlet pipe 8 is fixedly connected to an "L"-shaped driving rod 28, and the driving rod 28 is made of magnetic material. The top surface of the top group of driving leaves 22 is fixedly connected to a second magnetic block 29, and the second magnetic block 29 is magnetically attracted to the driving rod 28; the filter 13 is made of elastic material. When the rotating shaft 21 in this application rotates, the second magnetic block 29 on the driving leaf 22 will intermittently pass through the driving rod 28. When the driving rod 28 is attracted by the second magnetic block 29, it will pull the filter 13. After the second magnetic block 29 is away from the driving rod 28, the filter 13 will reset and shake, thereby assisting in the discharge of impurities on the filter 13.
[0030] A conduit 30 is connected to the rotating shaft 21, and the conduit 30 is located above the piston 24. A hollow groove 32 is provided in the connecting frame 12, and a group of air outlet holes 31 connected to the hollow groove 32 are provided on the top surface of the inner wall of the connecting frame 12. The end of the conduit 30 away from the rotating shaft 21 is connected to the hollow groove 32; the interior of the rotating shaft 21 is filled with coolant, and when the piston 24 moves upward, it pushes the coolant in the rotating shaft 21. At this time, the coolant will enter the hollow groove 32 from the conduit 30, and finally spray onto the filter 13 from the liquid outlet to help impurities fall from the filter 13.
[0031] Example 2: Figure 7As shown, compared with Example 1, another embodiment of the present invention is: the inner wall of the circulation box 7 is slidably connected with a float 33, the side of the circulation box 7 close to the float 33 is fixedly connected with a pressure sensor 34, the outer wall of the circulation box 7 is provided with an alarm 35 which can be activated by the pressure sensor 34, and the side of the circulation box 7 close to the alarm 35 is connected with a liquid injection pipe; the coolant will slowly decrease due to evaporation and chemical reaction, and the coolant level in the circulation box 7 will decrease. At this time, the float 33 will move downward, and when the float 33 contacts the pressure sensor 34, the pressure sensor 34 will feel the change in pressure, thereby activating the alarm 35 to alarm, so as to remind the staff to add coolant in time to avoid affecting the normal operation of the hydraulic rod 4.
[0032] Working principle: Install the mounting base 1 on the mountain transport vehicle, and then fix the wind turbine blade on the holder 3. In order to ensure the safety of transporting the blade in the mountains, the angle of the mounting platform 2 can be adjusted by the hydraulic rod 4, so that the blade can be rotated. Before the hydraulic rod 4 works, the circulating pump drives the coolant to flow in the circulating pipe 6. At this time, the coolant will keep the hydraulic oil in the hydraulic rod 4 at a constant temperature, thereby ensuring the stability of the hydraulic rod 4, so as to improve the accuracy of adjusting the wind turbine blade. After the blade is rotated to the appropriate angle, it can avoid the blade from contacting obstacles such as mountains, trees, and rocks; cooling When the coolant circulates, it passes through the filter 13, so that impurities in the coolant are captured by the filter 13 to prevent the impurities from affecting the use effect of the coolant. When the coolant is working, the captured impurities will adhere to the filter 13 due to the flowing liquid. When the coolant stops circulating, the captured impurities can slide from the inclined filter 13 to the discharge chute 15 for temporary storage, so as to prevent the impurities from clogging the filter 13 and affecting the use of the filter 13. When it is necessary to discharge the impurities, the sealing component can no longer seal the discharge chute, and the impurities can be discharged from the discharge chute. When impurities need to be discharged, the round rod can be pushed downward manually so that the round rod drives the first sealing plate 16 to no longer seal the discharge groove. At this time, the impurities in the discharge chute 15 can be discharged mixed with the coolant. After the impurities are discharged, the round rod is released. At this time, the first spring will push the first sealing plate 16 to seal the discharge chute; when the first sealing plate 16 moves downward, it will push the gas in the chute 14 from the connecting pipe 20 into the movable groove 17. At this time, the gas will push the second sealing plate 18, so that the connecting groove 19 on the second sealing plate 18 enters the movable groove 17. At this time, the second sealing plate 18 can seal the discharge end of the discharge chute 15 to prevent more coolant from being discharged when impurities are discharged. When the first sealing plate 16 moves upward, the second sealing plate 18 will be reset under the pull of the second spring. At this time, impurities can enter the discharge chute 15 through the connecting groove 19 for storage. When the coolant in the present application circulates, the water flow will drive the driving blade 22 to rotate. At this time, the driving blade 22 will stir the circulation box 7, so that the thermostat 10 can speed up the coolant constant temperature rate when maintaining the coolant in the circulation box 7 at a constant temperature; when the shaft 21 rotates, the piston 24 can be driven up and down by the moving component. When the piston 24 moves upward, the through groove 23 will suck the coolant into the shaft 21. When the piston 24 moves downward, the coolant will be ejected from the through groove 23, thereby improving the fluidity of the coolant in the circulation box 7, so as to further improve the efficiency of the coolant constant temperature; when the shaft 21 in the present application rotates, the connecting rod 25 will pass through the first magnetic block 26. At this time, the connecting rod 25 will be attracted by the first magnetic block 26 to move upward, thereby achieving the upward movement of the piston 24. When the connecting rod 25 is away from the first magnetic block 26, the third spring will push the piston 24 downward. In this way, during the rotation of the shaft 21, the piston 24 can continue to move up and down; The filter 13 is made of elastic material. When the rotating shaft 21 in the present application rotates, the second magnetic block 29 on the driving blade 22 will intermittently pass through the driving rod 28. When the driving rod 28 is attracted by the second magnetic block 29, it will pull the filter 13. After the second magnetic block 29 moves away from the driving rod 28, the filter 13 will reset and shake, thereby assisting in the discharge of impurities on the filter 13; the inside of the rotating shaft 21 will be filled with coolant, and when the piston 24 moves upward, it will push the coolant in the rotating shaft 21. At this time, the coolant will enter the hollow groove 32 from the conduit 30, and finally spray onto the filter 13 from the liquid outlet to assist impurities in falling from the filter 13.
