Description

Technical Field

[0001] This invention relates to the field of antenna protection technology, and in particular to an antenna protective cover that is easy to install. Background Technology

[0002] Antennas are components in wireless equipment used to transmit or receive electromagnetic waves. During antenna use, to prevent damage from external environmental factors such as hail or falling rocks, a protective cover is usually installed on the outside of the antenna. During antenna operation, when high-frequency current passes through the antenna, it causes electromagnetic induction, resulting in eddy current loss and hysteresis loss, which leads to energy dissipation and heat generation. Most common antenna protective covers completely enclose the antenna, preventing the exchange of air between the inside and outside of the cover. The hot air inside the cover transfers heat to the outer surface through heat conduction by contacting the inner wall of the cover. Then, the external airflow carries away the heat from the antenna cover, thus completing the antenna's heat dissipation. However, when the wind speed is low enough that the heat generated by the antenna cannot be carried away in time, the temperature of the internal components of the antenna will rise, seriously affecting the normal use of the antenna and causing communication to fail. Summary of the Invention

[0003] This invention provides an easy-to-install antenna protective cover, which solves the problem of poor heat dissipation in existing antenna protective covers.

[0004] The technical solution is: an easy-to-install antenna protective cover, comprising:

[0005] A base, the lower part of which is embedded with a rubber pad, and a protective shell is rotatably connected to the base. The lower part of the protective shell is provided with symmetrically distributed first ventilation openings. A guide rod is fixedly connected inside the protective shell. A symmetrically distributed first baffle and a symmetrically distributed second baffle are slidably connected to the guide rod. The first baffle and the adjacent second baffle are used to block the adjacent first ventilation openings on the protective shell. A first tension spring is provided between the first baffle and the second baffle and the protective shell.

[0010] Furthermore, the power assembly includes:

[0011] The wind cup is rotatably connected to the upper part inside the protective shell, and the upper part of the protective shell is provided with multiple second ventilation openings;

[0012] A transmission disc is fixedly connected to the wind cup, and circumferentially distributed centrifugal rods are slidably connected to the transmission disc. A second tension spring is provided between the centrifugal rods and the transmission disc.

[0013] The extrusion column is slidably connected to the protective shell. The wind cup and the winding frame are rotatably connected to the extrusion column.

The protrusions on the extrusion column slide along the adjacent guide grooves.

[0014] Furthermore, the guide groove is composed of an arc-shaped portion and a vertical portion, and the vertical portion is located on the side of the guide groove away from the take-up wheel. The protrusion of the extrusion column drives the take-up frame to rotate by extruding the arc-shaped portion of the guide groove.

[0015] Furthermore, a wind vane is provided on the upper part of the protective shell, which is used to detect the direction of the wind and drive the protective shell to rotate.

[0016] Furthermore, it also includes:

[0017] A steering component, disposed on the wind vane, is used to rotate the wind vane to change its relative position with the protective shell, thereby adjusting the windward position of the protective shell. The steering component includes:

[0018] A lifting frame is installed on the wind vane, and a pressing block is provided on the wind vane. An arc-shaped groove is provided inside the lifting frame, and the pressing block of the wind vane slides along the arc-shaped groove.

[0019] A limiting component is disposed on the wind vane to limit the relative position of the wind vane and the protective shell;

[0020] An adjustment component, located inside the protective housing, is used to move the lifting frame.

[0021] Furthermore, the limiting component includes:

[0022] Symmetrically distributed limiting blocks are slidably connected to the wind vane, and springs are fixed between the symmetrically distributed limiting blocks. The protective shell is provided with circumferentially distributed limiting holes, and the limiting blocks fix the wind vane through the limiting holes of the protective shell.

[0023] Furthermore, the adjustment component includes:

[0024] Rotating wheels, the same number as the centrifugal rods, are rotatably connected to the end of each adjacent centrifugal rod furthest from the wind cup;

[0025] A ring frame is disposed inside the protective shell. The rotating wheel contacts the ring frame. A frustum is provided on the inner side of the ring frame. The rotating wheel pushes the ring frame to move by pressing the frustum.

[0026] Multiple elastic telescopic rods are fixedly connected between the lifting frame and the ring frame.

[0027] Furthermore, it also includes:

[0028] A flipping assembly, disposed within the protective housing, is used to drive the winding reel to rotate independently. The flipping assembly includes:

[0029] Symmetrically distributed piston rods are all slidably connected to the protective shell. The ends of the symmetrically distributed piston rods away from the annular frame are slidably connected to an adjusting frame. The adjusting frame is rotatably connected to the winding wheel. The winding wheel is rotatably and slidably connected to the winding frame. The winding wheel is provided with multiple limiting grooves on the side near the winding frame, and the depth of one side of the limiting groove is greater than the depth of the other side.

[0030] The number of protruding rods is the same as the number of limiting grooves, and they are all fixed to the side of the winding frame near the winding wheel. The protruding rods slide within the adjacent limiting grooves.

[0031] The sealing components, the same number as the piston rods, are all mounted on the protective shell and are used to move the adjacent piston rods.

[0032] Furthermore, the sealing assembly includes:

[0033] A sealing shell is fixedly connected inside the protective shell, and the sealing shell is provided with an air inlet.

[0034] A sealing tube is slidably connected to the sealing shell. The sealing tube is fixedly connected to the annular frame and slidably connected to the piston rod. The sealing tube is provided with a connecting hole and an exhaust hole. The sealing tube communicates with the sealing shell through the connecting hole. A one-way valve is provided in both the connecting hole of the sealing tube and the air inlet of the sealing shell.

[0035] A sealing ring is fixed to the sealing tube. The sealing ring is in contact with the sealing shell. The sealing ring, the sealing shell, and the sealing tube together form a sealing cavity. The vent hole of the sealing tube is connected to the sealing cavity.

[0036] The beneficial effects are as follows: 1. By adjusting the positions of the first baffle and the second baffle, the present invention controls the gas flow area between the inside of the protective shell and the outside, so that the gas inside the protective shell can exchange with the outside when the outside wind speed is low. In this way, the flowing gas carries away the heat generated by the antenna, thereby reducing the heat accumulated around the line and ensuring the normal working condition of the antenna; the rubber pad on the base is used to increase the friction between the base and the installation position, reduce the probability of the base shifting during installation, and facilitate the installation by the staff.

[0037] 2. This invention detects wind speed and direction, and when the external wind speed affects the stability of the antenna, adjusts the relative position of the wind vane and the protective shell so that the side wall of the protective shell faces the windward direction, thus avoiding damage to the first and second baffles from the direct impact of the wind and affecting their normal use.

[0038] 3. After adjusting the direction of the protective shell, the present invention detects the change in external wind speed through the sealing tube. After the external wind speed stabilizes, it drives the winding wheel to rotate in the opposite direction to release the connecting rope on it, thereby reducing the shielding area of ​​the second baffle on the protective shell, allowing external air to enter the protective shell and carrying away the heat generated by the antenna operation.

Detailed Implementation

[0051] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0052] An easy-to-install antenna cover, such as Figures 1-5 As shown, it includes: a base 1, with a rubber pad embedded in the lower part of the base 1, a protective shell 2 rotatably connected to the base 1, a first vent symmetrically distributed on the lower part of the protective shell 2, a guide rod 3 fixedly connected inside the protective shell 2, a first baffle 4 and a second baffle 5 symmetrically distributed 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 inside the protective shell 2, a torsion spring 8 fixedly connected between the winding frame 7 and the protective shell 2; a winding wheel 9, located on the lower side of the winding frame 7, and connecting ropes 10 are provided between the first baffle 4 and the winding frame 7 and between the second baffle 5 and the winding wheel 9; and a power assembly, located inside the protective shell 2, used to drive the winding frame 7 and the winding wheel 9 to rotate and wind the connecting ropes 10.

[0053] Furthermore, such as Figures 1-3 As shown, the central angle corresponding to the first vent on the protective shell 2 is less than 90°.

[0054] The above solution provides a method to allow outside air to enter the protective shell 2 during antenna operation by controlling the separation of the first baffle 4 and the second baffle 5, thereby carrying away the heat generated during antenna operation and reducing the temperature inside the protective shell 2. The base 1 has threaded holes, and a rubber pad on the base 1 is located at the bottom of these threaded holes. During installation, the rubber pad is compressed to increase the friction between the base 1 and the installation position, increasing the resistance to rotation of the base 1. This reduces the probability of the base 1 deflecting during bolt rotation, causing misalignment between the threaded holes on the base 1 and the installation position, thus facilitating installation. The protective shell 2 is cylindrical, and the size of the first vent on the protective shell 2 controls the maximum flow area of ​​outside air entering the protective shell 2. Simultaneously, it ensures sufficient space on the side walls of the protective shell 2 to shield the first baffle 4 and the second baffle 5, preventing them from obstructing airflow in the initial state. Initially, the two first ventilation openings on the protective shell 2 are oriented left and right. The guide rod 3 is located at the lower part of the protective shell 2 and is annular. The center line of the guide rod 3, the central axis of the circle corresponding to the first baffle 4, and the central axis of the circle corresponding to the second baffle 5 all coincide with the central axis corresponding to the protective shell 2. The first baffle 4 and the adjacent second baffle 5 are close to each other and block the adjacent first ventilation openings 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 ventilation opening on the protective shell 2 is less than twice the central angle corresponding to the first baffle 4. This is to ensure that the adjacent first ventilation openings on the protective shell 2 can be completely blocked after the first baffle 4 contacts the adjacent second baffle 5. The winding frame 7 is rotatably connected to the lower part inside the protective shell 2. In this embodiment, the winding wheel 9 is fixedly connected 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 slack state and passes through the protective shell 2.

[0055] Furthermore, such as Figures 2-5 As shown, the power assembly includes: a wind cup 11, rotatably connected to the upper part of the protective shell 2, the upper part of the protective shell 2 having multiple second ventilation openings; a transmission disc 101, fixedly connected to the wind cup 11, with circumferentially distributed centrifugal rods 12 slidably connected to the transmission disc 101, and a second tension spring 13 between the centrifugal rods 12 and the transmission disc 101; and a pressing column 14, slidably connected to the protective shell 2, with the wind cup 11 and the winding frame 7 both rotatably connected to the pressing column 14, a connecting plate rotatably connected to the pressing column 14, a soft rope 15 fixedly connected between the centrifugal rods 12 and the connecting plate, centrally symmetrically distributed protrusions inside the pressing column 14, and centrally symmetrically distributed guide grooves 701 inside the winding frame 7, the protrusions on the pressing column 14 sliding along adjacent guide grooves 701.

[0056] Furthermore, such as Figure 8 , Figure 9 and Figure 11As shown, the guide groove 701 is composed of an arc-shaped part and a vertical part, and the vertical part is located on the side of the guide groove 701 away from the take-up wheel 9. The protrusion of the extrusion column 14 drives the take-up frame 7 to rotate by extruding the arc-shaped part of the guide groove 701.

[0057] Furthermore, such as Figures 1-3 , Figure 7 and Figure 8 As shown, a wind vane 16 is provided on the upper part of the protective shell 2. The wind vane 16 is used to detect the direction of the wind and drive the protective shell 2 to rotate.

[0058] The above solution provides a method to adjust the shielding area of ​​adjacent first vents on the protective shell 2 by rotating the winding frame 7 according to the wind speed and adjusting the first baffle 4 and the second baffle 5. 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. The protective shell 2 is provided with a plurality of circumferentially distributed second vents, and the shape of the second vents can be adjusted according to the actual situation. The external airflow passes through the second vents of the protective shell 2 and drives the wind cup 11 to rotate. The transmission disk 101 is located in the upper part of the protective shell 2. In this embodiment, there are eight centrifugal rods 12 that are evenly distributed. In actual use, they are separated from the wind cup 11. The number of centrifugal rods 12 can be adjusted. When the transmission disc 101 rotates, the centrifugal rods 12 move outward under the action of centrifugal force. The soft rope 15 passes through the wind cup 11 and the transmission disc 101. Initially, the soft rope 15 is in a slack state to ensure that the first baffle 4 and the second baffle 5 do not block the first ventilation opening. The protrusion on the extrusion column 14 is located at the lower end of the guide groove 701. The centrifugal rods 12 drive the extrusion column 14 to move upward through the soft rope 15. The extrusion column 14 is a counterweight used to enable it to move downward under its own weight. The protrusion on the extrusion column 14 drives the winding frame 7 to rotate counterclockwise through the extrusion guide groove 701. Figure 4 (Viewed from top to bottom), the guide groove 701 consists of an arc-shaped part and a vertical part, with the vertical part of the guide groove 701 located above the arc-shaped part; 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, it 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.

[0059] The working process of this antenna protective shell is as follows:

[0060] Preparation phase:

[0061] When this device protects the antenna, the operator should follow... Figure 1 As shown, the device is fitted onto the outside of the antenna, and then the position of the base 1 is fixed by bolts. At this time, neither the first baffle 4 nor the second baffle 5 blocks the first vent on the protective shell 2, so that the gas inside the protective shell 2 is connected to the outside, thereby increasing the heat dissipation efficiency of the antenna.

[0062] Usage process:

[0063] During antenna use, when wind blows (this example uses a wind direction from left to right), 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 above) The wind cup 11 drives all the centrifugal rods 12 to rotate through the transmission disk 101. During the rotation, the centrifugal rods 12 gradually move away from the central axis of the wind cup 11 due to the influence of centrifugal force (i.e., gradually extend out of the transmission disk 101). The movement of the centrifugal rods 12 stretches the adjacent second tension spring 13 and pulls the soft rope 15, so that the soft rope 15 changes from slack to taut. At the same time, the airflow enters the lower part of the protective shell 2 through the first vent and takes away the heat generated by the antenna.

[0064] As the outside wind speed increases, the rotation 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. The airflow extrusion column 14 extrudes the arc-shaped part of the guide groove 701 through the protrusion on it, causing the winding frame 7 to rotate counterclockwise. Figure 4 (Viewed from top to bottom) The rotation of the winding frame 7 causes the torsion spring 8 to store force and drive the winding wheel 9 to rotate synchronously. This causes the winding frame 7 and the winding wheel 9 to synchronously wind up the connecting rope 10 on it. In turn, the four connecting ropes 10 drive the two first baffles 4 and the two second baffles 5 to move synchronously. This causes the first baffle 4 and the adjacent second baffle 5 to move closer to each other and gradually block the adjacent first ventilation openings on the protective shell 2, reducing the flow area of ​​the first ventilation openings on the protective shell 2. The movement of the first baffle 4 and the second baffle 5 stretches the adjacent first tension spring 6, causing the first tension spring 6 to gradually store force until the protrusion on the extrusion column 14 moves to the junction of the arc-shaped part and the vertical part on the guide groove 701. At this time, the winding frame 7 and the winding wheel 9 stop rotating and wind up the connecting rope 10. At this time, the first baffle 4 contacts the adjacent second baffle 5 and completely blocks the adjacent first ventilation openings on the protective shell 2, preventing airflow from entering the protective shell 2. This avoids the airflow carrying impurities into the protective shell 2 after the external wind speed increases, which could damage the antenna and affect its normal use.

[0065] 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 blocking state of the first vent on the protective shell 2 by the first baffle 4 and the second baffle 5. If the external wind speed decreases, the centrifugal force on the centrifugal rod 12 decreases, the tension of the soft rope 15 on the extrusion column 14 decreases, and the extrusion column 14 moves downward under the action of gravity. The torsion spring 8 drives the winding frame 7 and the winding wheel 9 to rotate in the opposite direction to release the connecting rope 10. The first tension spring 6 drives the first baffle 4 and the second baffle 5 to move in the opposite direction to release the blockage of the first vent of the protective shell 2, allowing the airflow to re-enter the protective shell 2 until there is no wind outside. Then, the wind cup 11 and its parts stop rotating, the winding frame 7 resets under the action of the torsion spring 8, and the first baffle 4 and the second baffle 5 reset under the action of the first tension spring 6.

[0066] Example 2: Based on Example 1, as follows Figure 2 , Figure 3 and Figure 6 As shown, it also includes: a steering assembly, disposed on the wind vane 16, the steering assembly is used to drive the wind vane 16 to rotate and change its relative position with the protective shell 2, thereby adjusting the windward position of the protective shell 2. The steering assembly includes: a lifting frame 17, disposed on the wind vane 16, the wind vane 16 is provided with a pressing block, the lifting frame 17 is provided with an arc groove 1701, the pressing block of the wind vane 16 slides along the arc groove 1701; a limiting assembly, disposed on the wind vane 16, used to limit the relative position of the wind vane 16 and the protective shell 2; and an adjusting assembly, disposed inside the protective shell 2, used to drive the lifting frame 17 to move.

[0067] Furthermore, such as Figure 6 and Figure 7 As shown, the limiting component includes: symmetrically distributed limiting blocks 18, all slidably connected to the wind vane 16, springs 19 fixed between the symmetrically distributed limiting blocks 18, and circumferentially distributed limiting holes provided inside the protective shell 2, through which the limiting blocks 18 fix the wind vane 16.

[0068] Furthermore, such as Figures 2-6 As shown, the adjustment assembly includes: rotating wheels 20, the same number as the centrifugal rods 12, which are rotatably connected to the ends of adjacent centrifugal rods 12 away from the wind cup 11; an annular frame 21, which is disposed inside the protective shell 2, with the rotating wheels 20 in contact with the annular frame 21, and a frustum surface provided on the inner side of the annular frame 21, which the rotating wheels 20 push the annular frame 21 to move by pressing the frustum surface; and multiple elastic telescopic rods 2101, all of which are fixed between the lifting frame 17 and the annular frame 21.

[0069] The above solution provides a method to adjust the relative angle between the wind vane 16 and the protective shell 2 after the incoming wind increases, so that the lower sidewall of the protective shell 2 faces the direction of the incoming wind; the lifting frame 17 is located below the wind vane 16, and multiple 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 central angle corresponding to the horizontal projection of the arc-shaped grooves 1701 is 90 degrees, so that after the wind vane 16 and the protective shell 2 rotate relative to each other, the arrow of the wind vane 16 points directly backward (direction reference). Figure 1 Initially, the compression block of the wind vane 16 is located at the upper part of the arc groove 1701; there are two limiting blocks 18, and the back side of the two limiting blocks 18 is provided with an arc surface, so that the limiting blocks 18 can be separated from the adjacent limiting holes on the protective shell 2 by compression. The protective shell 2 has four circumferentially distributed limiting holes; in this embodiment, the ring frame 21 can be slidably connected to the protective shell 2 by a straight rod, so that the ring frame 21 can only move up and down relative to the protective shell 2. The diameter of the upper part of the truncated cone surface on the ring frame 21 is smaller than the diameter of its lower part. After the rotation speed of the wind cup 11 increases, the centrifugal rod 12 pushes the ring frame 21 upward under the action of centrifugal force through the rotating wheel 20. Initially, the rotating wheel 20 is located at the upper part of the truncated cone surface on the ring 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 of the elastic telescopic rod 2101 can push the lifting frame 17 upward, so that the spring 19 is compressed.

[0070] This embodiment follows the previous embodiment 1: During 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 squeezing force of the rotating wheel 20 on the inner annular surface of the ring frame 21 gradually increases. The rotating wheel 20 pushes the ring frame 21 to move upward. The ring frame 21 pushes the lifting frame 17 upward through the elastic telescopic rod 2101, so that the lifting frame 17 has an upward tendency. The arc groove 1701 squeezes the squeezing block of the wind vane 16, so that the wind vane 16 has a tendency to rotate clockwise. Figure 6 (Looking down from above), because 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 ring frame 21 moves upward to compress the elastic telescopic rod 2101.

[0071] As the wind speed gradually increases, the squeezing force of the rotating wheel 20 on the ring frame 21 gradually increases, and the force exerted by the ring 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. Then, the first baffle 4 and the second baffle 5 block the first ventilation opening of the protective shell 2, the limiting block 18 compresses the spring 19 and retracts into the wind vane 16, and the limiting block 18 separates from the limiting hole of the protective shell 2, releasing the fixation of the wind vane 16. The elastic telescopic rod 2101... 101 pushes the lifting frame 17 to move upward relative to the wind vane 16. The arc groove 1701 squeezes the squeezing 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 the left-facing direction to the rear-facing direction. After the squeezing block of the wind vane 16 moves to the bottom of the arc groove 1701, the lifting frame 17 stops moving. The wind vane 16 stops moving and rotates its arrow to the rear. The limiting block 18 aligns with the next limiting hole in the protective shell 2 and enters it under the push of the spring 19 to complete the limiting of the wind vane 16 again.

[0072] After the wind vane 16 stops rotating, its direction is misaligned with the wind direction. The airflow causes the wind vane 16 to rotate counterclockwise. The wind vane 16, through the limiting block 18, drives the protective shell 2 and its components to rotate synchronously, so that the lower sidewall of the protective shell 2 faces the windward direction, preventing the first baffle 4 and the second baffle 5 from being damaged by the direct impact of impurities carried by the wind, thus affecting the normal use of the device. Subsequently, when the wind force increases and the ring frame 21 moves upward again, the movement of the ring frame 21 only compresses the elastic telescopic rod 2101, and the lifting frame 1... 7 and its parts do not move. After the wind force decreases, the supporting force on the ring frame 21 decreases. The ring 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 squeezing block of the wind vane 16 again. The wind vane 16 and its parts repeat the above reverse action, which drives the limit block 18 to move in the opposite direction and resets 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.

[0073] Example 3: Based on Example 2, such as Figure 3 and Figures 8-11As shown, it also includes: a flipping assembly, which is disposed inside the protective shell 2. The flipping assembly is used to drive the take-up wheel 9 to rotate independently. The flipping assembly includes: symmetrically distributed piston rods 22, all slidably connected to the protective shell 2. The ends of the symmetrically distributed piston rods 22 away from the annular frame 21 are slidably connected to an adjusting frame 23. The adjusting frame 23 is rotatably connected to the take-up wheel 9. The take-up wheel 9 is rotatably and slidably connected to the take-up frame 7. The side of the take-up wheel 9 near the take-up frame 7 is provided with multiple limiting grooves 901, and the depth of one side of the limiting groove 901 is greater than the depth of the other side; protruding rods 24, the same number as the number of limiting grooves 901, are all fixed to the side of the take-up frame 7 near the take-up wheel 9. The protruding rods 24 slide within adjacent limiting grooves 901; and sealing assemblies, the same number as the number of piston rods 22, are disposed on the protective shell 2 and are used to drive adjacent piston rods 22 to move.

[0074] Furthermore, such as Figures 8-10 As shown, the sealing assembly includes: a sealing shell 25, fixedly connected to the protective shell 2, with an air inlet; a sealing tube 26, slidably connected to the sealing shell 25, fixedly connected to the annular frame 21, and slidably connected to the piston rod 22, with a connecting hole and an exhaust hole, the sealing tube 26 communicating with the sealing shell 25 through the connecting hole, and a one-way valve provided in both the connecting hole of the sealing tube 26 and the air inlet of the sealing shell 25; and a sealing ring 27, fixedly connected to the sealing tube 26, in contact with the sealing shell 25, the sealing ring 27, the sealing shell 25, and the sealing tube 26 together forming a sealing cavity 271, with the exhaust hole of the sealing tube 26 communicating with the sealing cavity 271.

[0075] The above solution provides a method to move the second baffle 5 after the external wind speed stabilizes, allowing the gas inside and outside the protective shell 2 to circulate again; there are two piston rods 22, and the adjusting frame 23 is located at the lower end of the two piston rods 22. In this embodiment, the winding wheel 9 and the winding frame 7 are rotatably and slidably connected. The adjusting frame 23 is located in the lower part inside the protective shell 2. The adjusting frame 23 is used to drive the winding wheel 9 to move. The depth of the limiting groove 901 gradually decreases in the counterclockwise direction. Figure 9(From top to bottom), after the take-up reel 9 moves downward relative to the take-up frame 7, the take-up reel 9 releases the connecting rope 10 on it clockwise relative to the take-up frame 7, causing the second baffle 5 to move under the action of the adjacent first tension spring 6 and separate 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 take-up frame 7 contacts the take-up reel 9. The take-up frame 7 squeezes the limiting groove 901 through the protruding rod 24, causing the take-up reel 9 to rotate synchronously. The sealing shell 25 is located on 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. A retaining ring is provided above the exhaust hole in the sealing tube 26 to limit the piston. The piston rod 22 moves a distance relative to the sealing tube 26. The piston rod 22 divides the sealing tube 26 into upper and lower chambers. Initially, the uppermost side of the piston rod 22 is in contact with the sealing tube 26. The sealing tube 26 is connected to the sealing shell 25 through the one-way valve in its upper connecting hole. The flow area of ​​the exhaust hole on the sealing tube 26 is smaller than the flow area of ​​the lower chamber inside the sealing tube 26. This is used to reduce the speed at which gas is discharged from the sealing tube 26 and to slowly release the gas in the lower part of the sealing tube 26. The one-way valves of the sealing tube 26 and the sealing shell 25 are used to prevent the gas from being discharged from either of them. The upper side of the sealing ring 27 is flush with the upper side of the sealing shell 25. Initially, the sealing cavity 271 is not connected to the outside.

[0076] This embodiment follows the above embodiment 2: During the upward movement of the ring frame 21, the elastic telescopic rod 2101 is gradually compressed, the ring frame 21 drives the sealing tube 26 to move upward, 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, the gas in the chamber enters the sealing cavity 271 through the exhaust hole on the sealing tube 26, at this time the sealing cavity 271 is sealed, the sealing cavity 271 and the lower chamber of the sealing tube 26 are pressurized at the same time, during this process, the outside gas enters into the sealing shell 25 through the one-way valve to replenish it, 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, and then changes the direction of the protective shell 2, at this time the sealing ring 27 separates from the sealing shell 25, the sealing cavity 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 to the left of the second baffle 5.

[0077] If the outside 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 adjusting frame 23 does not move either.

[0078] If the external wind speed no longer increases, the ring frame 21 will no longer move upward, and the elastic telescopic rod 2101 will no longer be 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 protrusion 24 on the limiting groove 901 is reduced, allowing the winding wheel 9 to 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 area of ​​obstruction of the first vent on the protective shell 2, allowing the gas inside the protective shell 2 to circulate with the external gas. The movement of the second baffle 5 drives the take-up wheel 9 to rotate clockwise via the adjacent connecting rope 10 until the protruding rod 24 moves to the other end of the limiting groove 901. At this point, the take-up 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. The gas in the lower chamber of the sealing tube 26 is compressed again, causing the piston rod 22 to drive the take-up wheel 9 to move upward via the adjusting frame 23. The protruding rod 24 squeezes the limiting groove 901 to make the take-up wheel 9 rotate counterclockwise to wind up the adjacent connecting rope 10. This causes the second baffle 5 to block the corresponding position of the first vent on the protective shell 2 again. During this process, the sealing tube 26 still moves upward relative to the piston rod 22.

[0079] After the wind speed decreases, as the ring frame 21 moves the sealing tube 26 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 upward, causing the piston rod 22 and its parts to move to the initial state. During this process, the protruding rod 24 causes the winding wheel 9 to rotate and reset relative to the winding frame 7 by squeezing the limiting groove 901. The sealing tube 26 stops moving after the ring frame 21 is reset. 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.
