DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 3 As shown, a deep foundation pit protection device comprises a guardrail 1; a plurality of rotating shafts 101 are rotatably connected to the middle part of the guardrail 1; a plurality of railings 106 are fixedly connected to the middle part of the guardrail 1; the rotating shaft 101 is arranged between two adjacent railings 106; a baffle 102 is fixedly connected to the end of the rotating shaft 101; a plurality of first connecting blocks 103 are fixedly connected to the middle part of the guardrail 1; a plurality of second connecting blocks 104 are fixedly connected to the side wall of the baffle 102; the second connecting block 104 is arranged on a side close to the first connecting block 103; an elastic rope 105 is fixedly connected between the first connecting block 103 and the second connecting block 104; when working, when a vehicle passes by the guardrail 1, the gravel squeezed by the tire of the car flies toward the deep foundation pit, the baffle 102 blocks the gravel, and part of the gravel is blocked by the baffle 102 outside the deep foundation pit. In windy weather, the baffle 102 is blown by the wind and drives the rotating shaft 101 to rotate together, and the wind blows through the gap between two adjacent baffles 102. When the wind decreases or stops, since the corresponding first connecting block 103 and the second connecting block 104 are connected with an elastic rope 105, the elastic rope 105 pulls the baffle 102 back by its own elastic force. By setting the baffle 102, the gravel stretched up when the vehicle passes by can be blocked, so that the gravel is blocked outside the deep foundation pit instead of flying into the deep foundation pit, reducing the problem of damage to the workers or equipment in the foundation pit caused by the gravel falling into the deep foundation pit. At the same time, when the wind is strong, the baffle 102 can rotate together with the rotating shaft 101, so that the wind can blow through the gap between two adjacent baffles 102, reducing the baffle 102's blocking of the wind, and reducing the problem of damage to the bolts fixing the guardrail 1 due to excessive wind resistance.

[0025] like Figure 4 As shown, a third connecting block 2 is fixedly connected to the middle of the baffle 102; a plurality of flashlights 201 are fixedly connected to the middle of the third connecting block 2; when in operation, when visibility is poor in rainy weather, the flashlight 201 is turned on, and at this time, the flashlight 201 flashes a red warning light to remind and warn passing vehicles and pedestrians. By setting the flashlight 201, when visibility is obstructed in rainy weather, the flashlight 201 can be turned on, and the flashing red light of the flashlight 201 can be used to remind and warn passing vehicles and pedestrians, making the guardrail 1 more eye-catching in a dim environment, reducing the problem of the guardrail 1 being difficult to see clearly due to dim weather and thus difficult to provide normal protection.

[0026] like Figure 4 As shown, the top and bottom of the third connecting block 2 are fixedly connected to the first supporting block 3; a slide groove 301 is opened in the middle of the first supporting block 3; a cleaning brush 302 is slidably connected in the slide groove 301; the bristles on the cleaning brush 302 are in contact with the flashlight 201; during operation, when there is a lot of dust attached to the surface of the flashlight 201, the cleaning brush 302 is slid, and the cleaning brush 302 can clean the dust on the flashlight 201 at this time. By setting the cleaning brush 302, when there is a lot of dust attached to the surface of the flashlight 201, the cleaning brush 302 can be slid to clean the surface of the flashlight 201, so that the dust attached to the surface of the flashlight 201 is cleaned off, so that the surface of the flashlight 201 is kept clean, and the dust blocking the warning light emitted by the flashlight 201 is reduced.

[0027] like Figure 3 As shown, a plurality of first magnets 4 are fixedly connected to the bottom of the railing 106; a plurality of second magnets 401 are fixedly connected to the top of the baffle 102; the first magnets 4 and the second magnets 401 are arranged to attract each other; during operation, when the wind force decreases or disappears and the elastic rope 105 pulls the baffle 102 to rotate, the first magnets 4 and the second magnets 401 gradually approach and attract each other, and finally the baffle 102 remains stable. Through the attraction arrangement of the first magnets 4 and the second magnets 401, when the wind force decreases or disappears, the baffle 102 can quickly restore to a stable state under the suction force of the first magnets 4 and the second magnets 401, and continue to block the gravel flying toward the foundation pit. At the same time, when the wind force is small or there is no wind, the suction force of the first magnets 4 and the second magnets 401 reduces the shaking of the baffle 102 and improves the stability of the baffle 102.

[0028] like Figure 5 As shown, a plurality of second support blocks 5 are fixedly connected to one side of the middle part of the baffle 102 close to the deep foundation pit; a bell 501 is fixedly connected to the end of the second support block 5; when working, the wind blows the baffle 102 to rotate the baffle 102, and at this time the bell 501 swings with the baffle 102, and makes a sound to remind passers-by. By setting the bell 501, when the wind blows the baffle 102, the bell 501 can swing with the baffle 102 and make a sound to remind passers-by, thereby further improving the safety protection function of the guardrail 1.

[0029] like Figure 3As shown, a plurality of counterweight blocks 6 are fixedly connected to the side wall of the baffle 102; the plurality of counterweight blocks 6 are arranged near the bottom of the baffle 102; by arranging the counterweight blocks 6, the center of gravity of the baffle 102 can be moved downward, so that the baffle 102 can remain stable when there is no wind or the wind force is small, and the shaking of the baffle 102 is reduced, thereby improving the blocking effect of the baffle 102 on gravel. At the same time, the counterweight blocks 6 can quickly stabilize the baffle 102 after the rotation of the baffle 102 is completed, thereby improving the stability of the baffle 102.

[0030] like Figure 3 As shown, a plurality of reflective stickers 7 are fixedly connected to the side wall of the counterweight block 6; the plurality of reflective stickers 7 are evenly arranged on the side wall of the counterweight block 6; by arranging the reflective stickers 7, when the car lights shine on the reflective stickers 7 at night, the reflective stickers 7 can reflect light, and the reflected light can remind and warn passers-by, thereby further improving the safety of the device.

[0031] During operation, when a vehicle passes by the guardrail 1 and the gravel lifted up by the tires of the vehicle flies toward the deep foundation pit, the baffle 102 blocks the lifted gravel, and part of the gravel is blocked outside the deep foundation pit by the baffle 102. When it is windy, the baffle 102 is blown by the wind and drives the rotating shaft 101 to rotate together, and the wind blows through between two adjacent baffles 102. When the wind decreases or stops, since the corresponding first connecting block 103 and the second connecting block 104 are connected with an elastic rope 105, the elastic rope 105 pulls the baffle 102 back by its own elastic force. When the visibility is poor in rainy weather, the flashlight 201 is turned on, and the flashlight 201 flashes a red warning light to remind and warn passing vehicles and pedestrians. When there is a lot of dust attached to the surface of the flashlight 201, the cleaning brush 302 is slid, and the cleaning brush 302 can clean the dust on the flashlight 201. When the wind force decreases or disappears, the elastic rope 105 pulls the baffle 102 to rotate, and the first magnet 4 and the second magnet 401 gradually approach and attract each other, eventually making the baffle 102 stable. The wind blows the baffle 102 to rotate the baffle 102. At this time, the bell 501 swings with the baffle 102 and makes a sound to remind passers-by. By setting the counterweight 6, the center of gravity of the baffle 102 can be moved downward. When there is no wind or the wind force is small, the baffle 102 can be kept stable, the shaking of the baffle 102 is reduced, and the blocking effect of the baffle 102 on gravel is improved. At the same time, the counterweight 6 can quickly stabilize the baffle 102 after the rotation of the baffle 102 is completed, thereby improving the stability of the baffle 102. By setting the reflective sticker 7, when the car lights shine on the reflective sticker 7 at night, the reflective sticker 7 can reflect light, and the reflected light reminds and warns passers-by, further improving the safety of the device.
