When the upper portion of the first protection assembly 300 is accidentally impacted, the upper portion of the first protection assembly 300 is inclined to a larger extent than the lower portion, so that the upper portion of the first side bracket 100 is inclined to a larger extent than the lower portion of the first side bracket 100, at this time, the length of the first spring 132 stretched is longer than the length of the second spring 142 stretched, therefore, the sliding distance of the first sealing block 131 along the axis of the first sealing tube 130 is longer than the sliding distance of the second sealing block 141 along the axis of the second sealing tube 140, so that the volume of the area formed by the first chamber 111 and the first sealing tube 130 is increased by an amount greater than the volume of the area formed by the second chamber 112 and the second sealing tube 140, at this time, under the action of the gas pressure difference, the isolation plate 120 moves vertically upwards until the sum of the force of the volume of the area formed by the first chamber 111 and the first sealing tube 130 on the isolation plate 120 and the gravity of the first protection assembly 300 is equal to the sum of the force of the gravity of the second chamber 112 and the second sealing tube 140 on the isolation plate 120, and the force of the isolation plate 120 of the area formed by the first protection assembly 300 stops moving vertically in the direction of the isolation plate 300, so that the first protection assembly is prevented from moving vertically upwards from the first protection assembly 300 beyond the first protection assembly to the first protection assembly, and thus the first protection assembly, and thus the barrier assembly is prevented from moving vertically upwards beyond the isolation assembly 300. Similarly, when the lower portion of the first protection assembly 300 is accidentally impacted, the lower portion of the first protection assembly 300 is inclined to a larger extent than the upper portion, so that the lower portion of the first side bracket 100 is inclined to a larger extent than the upper portion of the first side bracket 100, the stretched length of the second spring 142 is longer than the stretched length of the first spring 132, and therefore the sliding distance of the second sealing block 141 along the axis of the second sealing tube 140 is longer than the sliding distance of the first sealing block 131 along the axis of the first sealing tube 130, so that the volume of the area formed by the communication between the second chamber 112 and the second sealing tube 140 is increased by an amount greater than the volume of the area formed by the communication between the first chamber 111 and the first sealing tube 130, and at this time, the isolation plate 120 moves vertically downwards under the action of the gas pressure difference, until the sum of the force of the area formed by the communication between the first chamber 111 and the first sealing tube 130 to the isolation plate 120 and the gravity of the isolation plate 120 and the weight of the first protection assembly 300 is equal to the sliding distance of the first sealing block 141 along the axis of the second sealing tube 140 to the area formed by the first sealing block 131, and the barrier assembly is prevented from moving vertically downwards beyond the first protection assembly 300 beyond the vertical barrier assembly 300, and thus the barrier assembly is prevented from moving vertically downwards from the first protection assembly to the lower isolation plate 120 beyond the vertical barrier 300. When the middle portion of the first protection assembly 300 is impacted accidentally, the upper portion and the lower portion of the first protection assembly 300 are both effective protection areas, so that the impact objects cannot pass through the first protection assembly 300 and enter the construction area.
It should be added that a plurality of first sealing pipes 130 may be disposed at the upper portion of the first side bracket 100, and a second sealing pipe 140 may be disposed at the lower portion of the first side bracket 100, so that when the first protection assembly 300 is accidentally impacted, the volume of the area formed by the communication between the second chamber 112 and the second sealing pipe 140 and the volume of the area formed by the communication between the first chamber 111 and the first sealing pipe 130 may vary more, and thus the distance of the movement of the separation plate 120 may be more significant under the action of the gas pressure difference.
In a further embodiment, as shown in fig. 3, the first protection assembly 300 includes a first frame 310 and a plurality of first steel ropes 320, wherein the plurality of first steel ropes 320 are distributed in parallel and are disposed on the first frame 310 at intervals, and two sides of the first frame 310 are fixedly connected with the partition plate 120. In this embodiment, the first protection assembly 300 is designed to be composed of the first frame 310 and the plurality of first steel ropes 320 because the first steel ropes 320 have better toughness and better oxidation resistance than the aluminum alloy tube, and are not easily corroded in severe environments.

When the first protection assembly 300 is not impacted accidentally, the first protection assembly 300 and the second protection assembly 400 are in a superposition state, specifically, the first steel rope 320 and the second steel rope 420 are in a superposition state, and when wind is blown directly from one side of the first protection assembly 300 or blown directly from one side of the second protection assembly 400, wind force does not act on the first steel rope 320 and the second steel rope 420 at the same time, so that the windward area of the protection fence can be reduced, and the protection fence is prevented from being broken or toppled over in a strong wind environment.
When the first guard assembly 300 is subjected to an unexpected impact, the first guard assembly 300 is forced to move vertically upward, and the second guard assembly 400 is fixed to the first side bracket 100, so that the first guard assembly 300 and the second guard assembly 400 are spread out in a height direction, and thus the second steel ropes 420 and the first frame 310 are spread out in a height direction, and at this time, the first steel ropes 320 and the second steel ropes 420 are not overlapped in the height direction, so that a distance between two adjacent steel ropes in a guard area of the guard rail is reduced, and thus an impact is prevented from entering into a construction area through a gap between the steel ropes.

When the first steel ropes 320 and the second steel ropes 420 are equally spaced, if the moving distance of the first protection assembly 300 is just an integer multiple of the spacing distance, the first steel ropes 320 and the second steel ropes 420 still are in a superposed state, that is, the spacing between the steel ropes cannot be reduced, so that the impact is prevented from entering the construction area through the gaps between the steel ropes, and the spacing between the adjacent two first steel ropes 320 in the upper and lower side areas of the first frame 310 is smaller than the spacing between the adjacent two first steel ropes 320 in the middle area of the first frame 310, and the spacing between the adjacent two second steel ropes 420 in the upper and lower side areas of the second frame 410 is smaller than the spacing between the adjacent two second steel ropes 420 in the middle area of the second frame 410.
