Description

Technical Field

[0001] The present invention relates to the technical field of antenna protection, and in particular to an antenna protection cover which is easy to install. Background Art

[0002] The antenna is a component in radio equipment used to transmit or receive electromagnetic waves. During the use of the antenna, in order to prevent the antenna from being damaged by external environmental influences such as hail, falling rocks, etc., a protective cover is usually installed outside the antenna to protect the antenna. During the operation of the antenna, when the high-frequency current passes through the antenna, the high-frequency current causes electromagnetic induction, resulting in eddy current loss and hysteresis loss, thereby causing energy dissipation and heat generation. Most of the existing common antenna protective covers completely wrap the antenna, and the gas inside the antenna protective cover cannot be exchanged with the external gas. The hot air inside the antenna protective cover contacts the inner wall of the protective cover, and then transfers the heat to the outer surface through heat conduction. After that, the external airflow takes away the heat on the antenna protective cover, thereby completing the heat dissipation of the antenna. However, when the wind speed is so low that the heat generated by the antenna cannot be taken out in time, it will cause the temperature of the internal components of the antenna to rise, seriously affecting the normal use of the antenna and causing communication to be unable to proceed normally.

DETAILED DESCRIPTION

[0019] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0020] An antenna protection cover that is easy to install, such as Figure 1-Figure 5 As shown, it includes: a base 1, a rubber pad is embedded in the lower part of the base 1, a protective shell 2 is rotatably connected to the base 1, and a symmetrically distributed first vent is provided at the lower part of the protective shell 2, a guide rod 3 is fixed in the protective shell 2, and a symmetrically distributed first baffle 4 and a symmetrically distributed second baffle 5 are slidably connected to the guide rod 3, the first baffle 4 and the adjacent second baffle 5 are used to block the adjacent first vents on the protective shell 2, and a first tension spring 6 is provided between the first baffle 4 and the second baffle 5 and the protective shell 2; a winding frame 7, rotatably connected to the protective shell 2, a torsion spring 8 is fixed between the winding frame 7 and the protective shell 2; a winding wheel 9, arranged on the lower side of the winding frame 7, and a connecting rope 10 is provided between the first baffle 4 and the winding frame 7 and between the second baffle 5 and the winding wheel 9; a power component, arranged in the protective shell 2, for driving the winding frame 7 and the winding wheel 9 to rotate and reel in the connecting rope 10.

[0021] Further, such as Figure 1-Figure 3 As shown, the central angle corresponding to the first vent on the protective shell 2 is less than 90°.

[0022] The above scheme provides a method for controlling the separation of the first baffle 4 and the second baffle 5 during the operation of the antenna, so that outside air enters the protective shell 2 to take away the heat generated by the antenna during operation, thereby reducing the temperature inside the protective shell 2; a threaded hole is provided on the base 1, and the rubber pad on the base 1 is located at the bottom of the threaded hole. During the installation of the base 1, the friction between the base 1 and the installation position is increased by compressing the rubber pad, so that the resistance to the rotation of the base 1 is increased, thereby reducing the probability of the base 1 being deflected when the staff turns the bolt, resulting in the threaded hole on the base 1 and the threaded hole at the installation position being misaligned, thereby facilitating the staff to install the device. The protective shell 2 is cylindrical, and the size of the first vent on the protective shell 2 is used to control the maximum flow area of ​​the outside wind entering the protective shell 2, while allowing the side wall of the protective shell 2 to have enough space to block the first baffle 4 and the second baffle 5, so that the first baffle 4 and the second baffle 5 will not affect the wind in the initial state. Circulation, initially, the two first vents on the protective shell 2 are facing left and right, the guide rod 3 is located at the lower part of the protective shell 2, and the guide rod 3 is annular, the center line of the guide rod 3, the center axis of the circle corresponding to the first baffle 4 and the center axis of the circle corresponding to the second baffle 5 all coincide with the center axis corresponding to the protective shell 2, the first baffle 4 and the adjacent second baffle 5 are close to each other, blocking the adjacent first vents on the protective shell 2, the central angle corresponding to the first baffle 4 is the same as the central angle corresponding to the second baffle 5, and the central angle corresponding to the first vent on the protective shell 2 is less than twice the central angle corresponding to the first baffle 4, which is used to completely block the adjacent first vents on the protective shell 2 after the first baffle 4 contacts the adjacent second baffle 5; the winding frame 7 is rotatably connected to the lower part of the protective shell 2; in this embodiment, the winding wheel 9 is fixed to the winding frame 7, and the winding frame 7 directly drives the winding wheel 9 to rotate. Initially, the connecting rope 10 is in a loose state, and the connecting rope 10 passes through the protective shell 2.

[0023] Further, such as Figure 2-Figure 5 As shown, the power assembly includes: a wind cup 11, which is rotatably connected to the upper part of the protective shell 2, and a plurality of second vents are provided on the upper part of the protective shell 2; a transmission disk 101, which is fixed to the wind cup 11, and a circumferentially distributed centrifugal rod 12 is slidably connected to the transmission disk 101, and a second tension spring 13 is provided between the centrifugal rod 12 and the transmission disk 101; an extrusion column 14, which is slidably connected to the protective shell 2, and the wind cup 11 and the winding frame 7 are both rotatably connected to the extrusion column 14, and a connecting plate is rotatably connected to the extrusion column 14, and a soft rope 15 is fixed between the centrifugal rod 12 and the connecting plate, and centrally symmetrically distributed protrusions are provided in the extrusion column 14, and centrally symmetrically distributed guide grooves 701 are provided in the winding frame 7, and the protrusions on the extrusion column 14 slide along adjacent guide grooves 701.

[0024] Further, such as Figure 8 、 Figure 9 and Figure 11As shown, the guide groove 701 consists of an arc portion and a vertical portion, and the vertical portion is located on the side of the guide groove 701 away from the winding wheel 9. The protrusion of the extrusion column 14 drives the winding frame 7 to rotate by extruding the arc portion of the guide groove 701.

[0025] Further, such as Figure 1-Figure 3 、 Figure 7 and Figure 8 As shown, a wind vane 16 is provided on the upper portion of the protective shell 2 , and the wind vane 16 is used to detect the direction of wind and drive the protective shell 2 to rotate.

[0026] The above scheme provides a method of driving the winding frame 7 to rotate according to the wind speed, and adjusting the blocking area of ​​the first baffle 4 and the second baffle 5 on the adjacent first ventilation openings on the protective shell 2; the wind cup 11 is an existing device, and its specific structure will not be described in detail. The wind cup 11 is located in the upper part of the protective shell 2, and a plurality of second ventilation openings distributed circumferentially are provided on the protective shell 2. The shape of the second ventilation opening can be adjusted according to actual conditions; the external air flow passes through the second ventilation opening of the protective shell 2 and drives the wind cup 11 to rotate, and the transmission disk 101 is located in the upper part of the protective shell 2. In this embodiment, there are eight centrifugal rods 12 distributed at equal intervals. In actual use, The number of core rods 12 can be adjusted. When the transmission disk 101 rotates, the centrifugal rod 12 moves toward the outside of the transmission disk 101 under the action of centrifugal force; the soft rope 15 passes through the wind cup 11 and the transmission disk 101. Initially, the soft rope 15 is in a relaxed state to ensure that the first baffle 4 and the second baffle 5 do not block the first vent. The protrusion on the extrusion column 14 is located at the lower end of the guide groove 701. The centrifugal rod 12 drives the extrusion column 14 to move upward through the soft rope 15. The extrusion column 14 is a counterweight block used to enable it to move downward under the action of its own gravity. The protrusion of the extrusion column 14 drives the winding frame 7 to rotate counterclockwise ( Figure 4 , viewed from top to bottom), the guide groove 701 consists of an arcuate portion and a vertical portion, and the vertical portion of the guide groove 701 is located above its arcuate portion; initially, the arrow of the wind vane 16 points to the direction of the first vent on the left side of the protective shell 2. The wind vane 16 is used to detect the direction of the wind and, after the wind direction changes, drives the protective shell 2 to rotate so that the first vent on the left side of the protective shell 2 faces the direction of the wind.

[0027] The working process of this antenna protective shell is as follows: Preparation stage: When this device is protecting the antenna, the staff Figure 1 As shown, the device is put on the outside of the antenna, and then the position of the base 1 is fixed by bolts. At this time, the first baffle 4 and the second baffle 5 do not block the first vent on the protective shell 2, so that the gas in the protective shell 2 remains connected to the outside, thereby increasing the heat dissipation efficiency of the antenna.

[0028] Usage process: During the use of the antenna, when there is wind blowing, this article takes the wind direction from left to right as an example for description. Since the arrow of the wind vane 16 points to the left, the wind vane 16 does not rotate after contacting the airflow, the protective shell 2 does not rotate, and the wind cup 11 rotates clockwise under the action of the airflow after contacting the airflow ( Figure 4 , viewed from top to bottom), the wind cup 11 drives all the centrifugal rods 12 to rotate through the transmission disk 101. During the rotation process, the centrifugal rods 12 are gradually moved away from the central axis of the wind cup 11 under the influence of centrifugal force (that is, gradually extend out of the transmission disk 101). The movement of the centrifugal rods 12 stretches the adjacent second tension springs 13 and pulls the soft rope 15, so that the soft rope 15 changes from loose to tight. At the same time, the airflow enters the lower part of the protective shell 2 through the first ventilation port to take away the heat generated by the antenna.

[0029] As the external wind speed increases, the speed of the wind cup 11 increases, and the centrifugal force on the centrifugal rod 12 increases. At this time, the soft rope 15 drives the extrusion column 14 to move upward, and the airflow extrusion column 14 squeezes the arc portion of the guide groove 701 through the convex block on it to make the winding frame 7 rotate counterclockwise ( Figure 4 The cam 8 is moved upwards to move the first and second cams 5 so that the cam 8 can move upwards and downwards, thereby preventing the cam 8 from moving upwards and downwards, and preventing the cam 8 from moving upwards and downwards.

[0030] After the first baffle 4 and the second baffle 5 block the first vent of the protective shell 2, if the wind speed continues to increase, the protrusion of the extrusion column 14 moves upward along the vertical part of the guide groove 701, and the winding frame 7 does not move, maintaining the first baffle 4 and the second baffle 5 blocking the first vent on the protective shell 2. If the external wind speed decreases, the centrifugal force on the centrifugal rod 12 decreases, and the pulling force of the soft rope 15 on the extrusion column 14 decreases. The extrusion column 14 moves downward under the action of gravity, and the torsion spring 8 drives the winding frame 7 and the winding wheel 9 to rotate in reverse to release the connecting rope 10. The first tension spring 6 drives the first baffle 4 and the second baffle 5 to move in reverse to release the blockage of the first vent of the protective shell 2, allowing the airflow to enter the protective shell 2 again. Until there is no wind outside, the wind cup 11 and the parts thereon stop rotating, and the winding frame 7 is reset under the action of the torsion spring 8, and the first baffle 4 and the second baffle 5 are reset under the action of the first tension spring 6.

[0031] Example 2: Based on Example 1, Figure 2 、 Figure 3 and Figure 6 As shown, it also includes: a steering component, which is arranged on the wind vane 16, and is used to drive the wind vane 16 to rotate to change its relative position with the protective shell 2, thereby adjusting the windward position of the protective shell 2, and the steering component includes: a lifting frame 17, which is arranged on the wind vane 16, and an extrusion block is provided on the wind vane 16, and an arc groove 1701 is provided in the lifting frame 17, and the extrusion block of the wind vane 16 slides along the arc groove 1701; a limiting component, which is arranged on the wind vane 16, and is used to limit the relative position of the wind vane 16 and the protective shell 2; an adjusting component, which is arranged in the protective shell 2, and is used to drive the lifting frame 17 to move.

[0032] Further, such as Figure 6 and Figure 7 As shown, the limiting assembly includes: symmetrically distributed limiting blocks 18, all of which are slidably connected to the wind vane 16, springs 19 are fixed between the symmetrically distributed limiting blocks 18, and circumferentially distributed limiting holes are provided in the protective shell 2, and the limiting blocks 18 fix the wind vane 16 through the limiting holes of the protective shell 2.

[0033] Further, such as Figure 2-Figure 6 As shown, the adjustment component includes: rotating wheels 20, the number of which is the same as the number of centrifugal rods 12, which are respectively rotatably connected to the ends of adjacent centrifugal rods 12 away from the wind cup 11; an annular frame 21, which is arranged in the protective shell 2, and the rotating wheel 20 is in contact with the annular frame 21. A circular table surface is provided on the inner side of the annular frame 21, and the rotating wheel 20 pushes the annular frame 21 to move by squeezing the circular table surface; there are multiple elastic telescopic rods 2101, all of which are fixed between the lifting frame 17 and the annular frame 21.

[0034] The above solution provides a method for adjusting the relative angle between the wind vane 16 and the protective shell 2 after the wind increases, so that the side wall of the lower part of the protective shell 2 faces the direction of the wind; the lifting frame 17 is located at the lower part of the wind vane 16, and a plurality of arc-shaped grooves 1701 can be arranged circumferentially. The height of the arc-shaped grooves 1701 inside the lifting frame 17 gradually increases in the counterclockwise direction, and the corresponding central angle of the arc-shaped grooves 1701 on the horizontal projection is 90 degrees, which is used to make the wind vane 16 and the protective shell 2 rotate relative to each other, so that the arrow of the wind vane 16 points to the rear (direction reference Figure 1 ), initially, the extrusion block of the wind vane 16 is located at the upper part of the arc groove 1701; there are two limit blocks 18, and the back sides of the two limit blocks 18 are provided with arc surfaces, so that the limit blocks 18 can be separated from the adjacent limit holes on the protective shell 2 by extrusion, and the protective shell 2 has four limit holes distributed circumferentially; in this embodiment, the annular frame 21 can be connected to the protective shell 2 by sliding up and down through a straight rod, so that the annular frame 21 can only move up and down relative to the protective shell 2, and the diameter of the upper part of the circular table surface of the annular frame 21 is smaller than the diameter of its lower part. After the speed of the wind cup 11 increases, the centrifugal rod 12 pushes the annular frame 21 upward through the rotating wheel 20 under the action of centrifugal force. Initially, the rotating wheel 20 is located at the upper part of the circular table surface of the annular frame 21. Initially, the elastic telescopic rod 2101 has no stored force. When the external wind affects the stability of the antenna, the stored force state of the elastic telescopic rod 2101 can push the lifting frame 17 to move upward, causing the spring 19 to be compressed.

[0035] This embodiment is a continuation of the above-mentioned embodiment 1: in the process of the transmission disc 101 driving the centrifugal rod 12 to rotate, the centrifugal rod 12 drives the rotating wheel 20 to rotate synchronously. As the centrifugal rod 12 gradually extends out of the transmission disc 101, the extrusion force of the rotating wheel 20 on the inner annular surface of the annular frame 21 gradually increases, and the rotating wheel 20 pushes the annular frame 21 to move upward. The annular frame 21 pushes the lifting frame 17 upward through the elastic telescopic rod 2101, so that the lifting frame 17 has a tendency to move upward. The arc groove 1701 squeezes the extrusion block of the wind vane 16, so that the wind vane 16 has a tendency to rotate clockwise ( Figure 6 , viewed from top to bottom), since the limiting block 18 is limited by the limiting hole on the protective shell 2, the wind vane 16 does not rotate, the lifting frame 17 cannot move, and the annular frame 21 moves upward to compress the elastic telescopic rod 2101.

[0036] As the wind speed gradually increases, the squeezing force of the rotating wheel 20 on the annular frame 21 gradually increases, and the force of the annular frame 21 on the lifting frame 17 through the elastic telescopic rod 2101 gradually increases until the force of the lifting frame 17 driving the wind vane 16 to rotate is greater than the limiting force of the upper limit hole of the protective shell 2 on the limiting block 18, the first baffle 4 and the second baffle 5 block the first vent of the protective shell 2, the limiting block 18 compresses the spring 19 and retracts into the wind vane 16, the limiting block 18 separates from the limiting hole of the protective shell 2 to release the fixation of the wind vane 16, and the elastic telescopic rod 2 101 pushes the lifting frame 17 to move upward relative to the wind vane 16, and the arc groove 1701 squeezes the extrusion block of the wind vane 16. The wind vane 16 drives the parts on it to rotate counterclockwise, so that the wind vane 16 gradually changes from left to rearward facing, until the extrusion block of the wind vane 16 moves to the bottom of the arc groove 1701. The lifting frame 17 stops moving, and the wind vane 16 stops moving and rotates with its arrow pointing to the rear side. The limit block 18 is aligned with the next limit hole in the protective shell 2 and enters it under the push of the spring 19 to complete the limitation of the wind vane 16 again.

[0037] After the above-mentioned wind vane 16 stops rotating, the direction of the wind vane 16 is misaligned with the wind direction, and the airflow blows the wind vane 16 to rotate counterclockwise. The wind vane 16 drives the protective shell 2 and the parts thereon to rotate synchronously through the limit block 18, so that the side wall of the lower part of the protective shell 2 faces the windward direction, avoiding the first baffle 4 and the second baffle 5 from being damaged by the positive impact of impurities carried in the wind, affecting the normal use of the device. Later, when the wind force increases and the annular frame 21 moves upward again, the annular frame 21 moves only to compress the elastic telescopic rod 2101, and the lifting frame 1 7 and the parts thereon do not move. After the wind force decreases, the supporting force on the annular frame 21 decreases, and the annular frame 21 moves downward and resets under the action of gravity. The elastic telescopic rod 2101 extends and resets and pulls the lifting frame 17. The arc groove 1701 squeezes the extrusion block of the wind vane 16 again, and the wind vane 16 and the parts thereon repeat the above reverse action, driving the limit block 18 to move in the opposite direction and resetting the spring 19, so that the wind vane 16 is reset relative to the protective shell 2 until the wind blows the wind vane 16, causing the wind vane 16 to drive the protective shell 2 to rotate and reset.

[0038] Example 3: Based on Example 2, Figure 3 and Figures 8-11As shown, it also includes: a flip assembly, which is arranged in the protective shell 2, and the flip assembly is used to drive the winding wheel 9 to rotate separately. The flip assembly includes: symmetrically distributed piston rods 22, which are all slidably connected to the protective shell 2, and the symmetrically distributed piston rods 22 are slidably connected to the adjustment frame 23 at one end away from the annular frame 21. The adjustment frame 23 is rotatably connected to the winding wheel 9, and the winding wheel 9 is rotatably and slidably connected to the winding frame 7. A plurality of limiting grooves 901 are provided on the side of the winding wheel 9 close to the winding frame 7, and the depth of one side of the limiting groove 901 is greater than the depth of the other side; the convex rods 24, the number of which is the same as the number of limiting grooves 901, are all fixed to the side of the winding frame 7 close to the winding wheel 9, and the convex rods 24 are located in the adjacent limiting grooves 901 and slide; the sealing components, the number of which is the same as the number of piston rods 22, are all arranged on the protective shell 2, and are used to drive adjacent piston rods 22 to move.

[0039] Further, such as Figures 8-10 As shown, the sealing assembly includes: a sealing shell 25, which is fixed in the protective shell 2, and the sealing shell 25 is provided with an air inlet hole; a sealing tube 26, which is slidably connected to the sealing shell 25, the sealing tube 26 is fixed to the annular frame 21, and the sealing tube 26 is sealed and slidably connected to the piston rod 22, and the sealing tube 26 is provided with a communicating hole and an exhaust hole. The sealing tube 26 is connected with the sealing shell 25 through the communicating hole thereon, and a one-way valve is provided in the communicating hole of the sealing tube 26 and the air inlet hole of the sealing shell 25; a sealing ring 27, which is fixed to the sealing tube 26, and the sealing ring 27 is in contact with the sealing shell 25. The sealing ring 27, the sealing shell 25 and the sealing tube 26 together constitute a sealing cavity 271, and the exhaust hole of the sealing tube 26 is connected to the sealing cavity 271.

[0040] The above solution provides a method for driving the second baffle 5 to move after the external wind speed stabilizes, so that the gas inside and outside the protective shell 2 can circulate again; there are two piston rods 22, and the adjustment frame 23 is located at the lower end of the two piston rods 22. In this embodiment, the winding wheel 9 is rotatably and slidably connected to the winding frame 7. The adjustment frame 23 is located at the lower part of the protective shell 2. The adjustment frame 23 is used to drive the winding wheel 9 to move, and the depth of the limit groove 901 gradually decreases in the counterclockwise direction ( Figure 9, from top to bottom), after the winding wheel 9 moves downward relative to the winding frame 7, the winding wheel 9 releases the connecting rope 10 thereon clockwise compared to the winding frame 7, so that the second baffle 5 moves under the action of the adjacent first tension spring 6 and separates from the first baffle 4. Initially, the protruding rod 24 is located at the deeper end of the limiting groove 901, and the lower side of the winding frame 7 contacts the winding wheel 9. The winding frame 7 squeezes the limiting groove 901 through the protruding rod 24, driving the winding wheel 9 to rotate synchronously; the sealing shell 25 is located at the upper part of the protective shell 2, and the exhaust hole of the sealing tube 26 is located in the middle of the sealing shell 25. The sealing tube 26 is not separated from the sealing shell 25, and a retaining ring is provided above the exhaust hole in the sealing tube 26 to limit the piston The distance that the rod 22 and the sealing tube 26 move relative to each other, the piston rod 22 divides the sealing tube 26 into two upper and lower chambers. Initially, the uppermost side of the piston rod 22 contacts the sealing tube 26, and the sealing tube 26 is connected to the sealing shell 25 through the one-way valve in the communicating hole thereon. The flow area of ​​the exhaust hole on the sealing tube 26 is smaller than the flow area of ​​the lower chamber in the sealing tube 26, which is used to reduce the speed of gas discharge in the sealing tube 26 and to slowly release the gas in the lower part of the sealing tube 26. The one-way valve of the sealing tube 26 and the one-way valve of the sealing shell 25 are respectively used to prevent the gas in the two from being discharged. The upper side surface of the sealing ring 27 is flush with the upper side surface of the sealing shell 25. Initially, the sealing cavity 271 is not connected to the outside world.

[0041] This embodiment is a continuation of the above-mentioned embodiment 2: During the upward movement of the annular frame 21, the elastic telescopic rod 2101 is gradually compressed, the annular frame 21 drives the sealing tube 26 to move upward, and the sealing tube 26 drives the sealing ring 27 to move upward relative to the piston rod 22. The pressure of the gas in the lower chamber of the sealing tube 26 increases, and the gas in the chamber enters the sealed chamber 271 through the exhaust hole on the sealing tube 26. At this time, the sealed chamber 271 is sealed, and the sealed chamber 271 and the lower chamber of the sealing tube 26 are pressurized at the same time. During this process, the outside gas enters through the one-way valve on the sealing shell 25 for replenishment. When the first baffle 4 contacts the second baffle 5, the lifting frame 17 repeats the above process to adjust the direction of the wind vane 16, thereby changing the direction of the protective shell 2. At this time, the sealing ring 27 is separated from the sealing shell 25, and the sealed chamber 271 is connected to the outside. The gas in the lower chamber of the sealing tube 26 is gradually discharged through the exhaust hole on it, so that the piston rod 22 has a tendency to move downward relative to the sealing tube 26. The first baffle 4 is located on the left side of the second baffle 5.

[0042] If the external wind speed continues to increase, the annular frame 21 continues to move upward under the action of the centrifugal rod 12 and the rotating wheel 20, the elastic telescopic rod 2101 continues to be compressed, the annular frame 21 drives the sealing tube 26 to continue to move upward, the gas in the lower chamber of the sealing tube 26 continues to be compressed, the piston rod 22 cannot move downward, and the adjustment frame 23 does not move either.

[0043] If the external wind speed no longer increases, the annular frame 21 no longer moves upward, and the elastic telescopic rod 2101 is no longer compressed. As the gas in the sealing tube 26 is continuously discharged, when the air pressure in the lower chamber of the sealing tube 26 is restored, the piston rod 22 and the adjusting frame 23 move downward relative to the protective shell 2 under the action of gravity. At this time, the gas in the sealing tube 26 continues to be discharged, and the adjusting frame 23 drives the winding wheel 9 to move downward. The squeezing force of the protruding rod 24 on the limiting groove 901 is reduced, so that the winding wheel 9 can rotate clockwise relative to the winding frame 7. The first tension spring 6 drives the second baffle 5 to move in the opposite direction, reducing the blocking area of ​​the first vent on the protective shell 2, so that the gas in the protective shell 2 can circulate with the external gas. The second baffle 5 moves through the adjacent connecting rope 10 to drive the winding wheel 9 to rotate clockwise until the protruding rod 24 moves to the other end of the limit groove 901, the winding wheel 9 stops rotating and the second baffle 5 stops moving. During this process, if the wind speed increases again, the sealing tube 26 drives the piston rod 22 to move upward, and the gas in the lower chamber of the sealing tube 26 is compressed again, so that the piston rod 22 drives the winding wheel 9 to move upward through the adjusting frame 23. The protruding rod 24 squeezes the limit groove 901 to make the winding wheel 9 rotate counterclockwise to rewind the adjacent connecting rope 10, so that the second baffle 5 again blocks the corresponding position of the first vent on the protective shell 2. During this process, the sealing tube 26 still moves upward relative to the piston rod 22.

[0044] After the wind speed decreases, as the annular frame 21 drives the sealing tube 26 to move downward, the gas in the sealing shell 25 enters the sealing tube 26 through the one-way valve. The gas entering the lower chamber of the sealing tube 26 pushes the piston rod 22 to move upward, causing the piston rod 22 and the parts above it to move to the initial state. During this process, the protruding rod 24 squeezes the limiting groove 901 to rotate and reset the winding wheel 9 relative to the winding frame 7 until the annular frame 21 is reset and the sealing tube 26 stops moving. During this process, when the sealing ring 27 contacts the sealing shell 25, the sealing cavity 271 is sealed again, and the gas in the sealing tube 26 cannot be discharged.
