[0015] The present invention provides a safety warning fence for nuclear power engineering construction, which has the following beneficial effects: (1) For the safety warning fence for nuclear power engineering construction, the detection rod detects the flatness of the ground. After the limit between the support plate and the safety plate is released, the support plate moves downward and contacts the ground, increasing the contact area between the railing and the ground. When the ground is inclined, the increased contact area between the railing and the ground can provide more support, thereby increasing the stability of the railing. And increasing the contact area can reduce the risk of the railing tipping over or falling off, thus improving the safety of workers or other users.

[0016] (2) For the safety warning fence for nuclear power engineering construction, when multiple railings that need to be disassembled and spliced are involved, manually rotate the protection rod. The rotation of the protection rod drives the rotation of the protection bar. The rotation of the protection bar releases the limit between the protection bar and the L - shaped groove. The free ends of the two T - shaped telescopic plates move to release the limit on the splicing block, enabling the splicing block to be taken out from the interior of the placement frame. By setting limits to prevent accidental contact by personnel, the connection part of the fence is prevented from loosening. The anti - accidental - contact device can reduce the risk of personnel accidentally touching or misoperating the connection part of the railing, thereby reducing potential injuries and accidents. By reducing accidental contact, the incidence of workplace accidents can be reduced, which helps to maintain the safety of the site.

[0017] (3)The safety warning fence for nuclear power project construction squeezes two release rods by the movement of the protection plate. The two release rods move away from each other under the extrusion of the protection plate, causing the elastic plate to move rapidly towards the switch plate and push the splicing block to move, accelerating the separation of the splicing block from the placement frame, improving the efficiency of railing disassembly. In the case of railing disassembly, repair or replacement, the quick disassembly device can make these operations more convenient, without the need for complex tools or long-term operations, and the railing can be quickly disassembled and reinstalled.

[0018] (4)When tightening the two railings of the safety warning fence for nuclear power project construction, under the action of the scroll spring in the winding device, the winding device rotates to pull the winding rope to tighten. The tightening of the winding rope drives the connecting plate to move, and the movement of the connecting plate drives the two railings to tighten. Quick tightening of the railings can quickly tighten the railings in case of emergency to ensure the rapid evacuation of personnel, reduce chaos and danger. At the same time, certain limits need to be released before tightening the two railings to prevent accidental contact by personnel. Description of the Drawings

Detailed implementation manner

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-6One embodiment of the present invention is: a safety warning fence for nuclear power engineering construction, including a railing 1, a protection device and a docking device, wherein a support frame is fixedly installed on the surface of the railing 1, a splicing block 2 is fixedly installed on the surface of the railing 1, and a groove is opened on the surface of the splicing block 2, wherein the protection device includes a base 31, a detection rod 32, a safety rod 33, a safety plate 34, a fixing block 35, a force storage spring 36 and a support plate 37, the detection rod 32 moves upward to drive the safety rod 33 to move upward, the safety rod 33 moves upward to break away from the contact with the safety plate 34, the safety plate 34 moves in a direction away from the fixing block 35 to release the limit on the support plate 37, and after the limit between the support plate 37 and the safety plate 34 is released, the support plate 37 moves downward under the elastic force of the force storage spring 36, and the support plate 37 Moving downward and contacting the ground increases the contact area between the railing 1 and the ground, the base 31 is fixedly installed at the bottom of the railing 1, a detection groove is opened on the surface of the railing 1, the detection rod 32 is slidably installed on the inner wall of the detection groove, the safety rod 33 is fixedly installed on the surface of the detection rod 32, a moving groove is opened on the surface of the base 31, the safety plate 34 is slidably installed on the inner wall of the moving groove, the fixed block 35 is fixedly installed on the inner wall of the moving groove, the support plate 37 is slidably installed on the inner wall of the moving groove, and the support plate 37 is fixedly connected to the fixed block 35 through the force storage spring 36. When the ground is inclined, the increased contact area between the railing 1 and the ground can provide more support, thereby increasing the stability of the railing 1, and increasing the contact area can reduce the risk of the railing 1 overturning or falling off, thereby improving the safety of the staff or other users.

[0023] A safety groove is opened on the surface of the railing 1, and a calibration plate 38 is fixedly installed on the inner wall of the safety groove. A telescopic leg 311 is fixedly installed on the bottom of the calibration plate 38. A limit rod 39 is fixedly installed on the surface of the telescopic leg 311, and a limit plate 310 is slidably installed on the surface of the limit rod 39. The limit plate 310 moves toward the direction close to the railing 1 to release the limitation on the free end of the telescopic leg 311. After the limitation on the free end of the telescopic leg 311 is released, it moves downward quickly and inserts into the ground to provide further support for the railing 1, thereby further reducing the risk of the railing 1 overturning or falling off.

[0024] A No. 1 spring is arranged between the safety plate 34 and the movable groove. The end of the detection rod 32 close to the limit plate 310 is arranged as an inclined surface. The free end of the telescopic leg 311 is provided with a limit groove. The limit plate 310 contacts the limit groove. The safety plate 34 can be driven to reset through the No. 1 spring.

[0025] The docking device includes a placement frame 41, a switch plate 42, a T-shaped telescopic plate 43, a release rod 44, a protection plate 45, a fixing rod 461, a protection rod 46, a protection rod 47 and an L-shaped groove 48. The protection rod 46 is manually rotated, and the protection rod 47 rotates to release the limit of the protection rod 47 and the L-shaped groove 48. The two release rods 44 move back to back to drive the free ends of the two T-shaped telescopic plates 43 to move. The free ends of the two T-shaped telescopic plates 43 move to release the limit on the splicing block 2, so that the splicing block 2 can be taken out from the inside of the placement frame 41, so as to achieve the effect of facilitating the disassembly of the spliced ​​railing 1. The placement frame 41 is fixedly installed on the surface of the railing 1, the switch plate 42 is slidably installed on the surface of the placement frame 41, and the T-shaped telescopic plate 43 is fixedly installed on the placement frame 4 1 inner wall, the release rod 44 penetrates the surface of the T-shaped telescopic plate 43 and is fixedly connected to the switch plate 42, the protection plate 45 is slidably installed on the inner wall of the placement frame 41, the L-shaped groove 48 is fixedly installed on the surface of the protection plate 45, the fixing rod 461 is fixedly installed on the surface of the protection plate 45, the protection rod 46 is rotatably installed on the surface of the fixing rod 461, and the protection rod 47 is fixedly installed on the surface of the protection rod 46. By setting the limit, it is prevented that the fence connection is loosened by accidental touch by personnel, and the anti-accidental touch device can reduce the risk of accidental touch or misoperation of the connection part of the railing 1 by personnel, thereby reducing potential injuries and accidents. At the same time, moving the protection plate 45 to contact the release rod 44 and squeezing the release rod 44 can release all limits with one key, so as to achieve the effect of convenient disassembly and splicing of the completed railing 1.

[0026] A No. 2 spring is provided between the switch plate 42 and the placement frame 41 , and the protection rod 47 contacts the L-shaped groove 48 , which penetrates the inner and outer walls of the placement frame 41 , so that the switch plate 42 can be driven to reset by the No. 2 spring.

[0027] When the present embodiment is working, the railing 1 is placed around the area to be maintained, and the flatness of the ground is detected by the detection rod 32. If the ground is slightly inclined when the railing 1 is placed, the detection rod 32 moves upward due to the reaction force of the ground, and the detection rod 32 moves upward to drive the safety rod 33 to move upward, and the safety rod 33 moves upward to break away from the contact with the safety plate 34. After the safety plate 34 releases the contact with the safety rod 33, it moves in the direction away from the fixed block 35 under the elastic force of the No. 1 spring, and the safety plate 34 moves in the direction away from the fixed block 35 to release the limit on the support plate 37, and the support plate 37 and the safety plate 33 are in contact with each other. After the limit of 4 is released, it moves downward under the elastic force of the storage spring 36, and the support plate 37 moves downward and contacts the ground to increase the contact area between the railing 1 and the ground. If the ground is tilted to a large extent, the detection rod 32 continues to move upward. After the detection rod 32 continues to move upward to the specified position, the limit plate 310 contacts the inclined surface of the detection rod 32 and moves toward the railing 1. The limit plate 310 moves toward the railing 1 to release the limit on the free end of the telescopic leg 311. After the limit of the free end of the telescopic leg 311 is released, it moves downward quickly and inserts into the ground to provide further support for the railing 1.

[0028] When the railing 1 needs to be spliced and used, manually align the splicing block 2 to the surface of the switch board 42. Under the action of human force, the splicing block 2 squeezes the two switch boards 42. The two switch boards 42 move away from each other under the extrusion of the splicing block 2, allowing the splicing block 2 to enter the interior of the placement frame 41. The splicing block 2 continues to move inside the placement frame 41 and contacts the free end of the T-shaped telescopic plate 43, squeezing the free end of the T-shaped telescopic plate 43. The free ends of the two T-shaped telescopic plates 43 move away from each other under the extrusion of the splicing block 2, causing the splicing block 2 to continue to move into the interior of the placement frame 41. After the groove on the surface of the splicing block 2 contacts the free ends of the two T-shaped telescopic plates 43, the free ends of the two T-shaped telescopic plates 43 move towards each other to form a limit with the groove on the surface of the splicing block 2. When multiple railings 1 that need to be disassembled and spliced are involved, manually rotate the protection rod 46. The rotation of the protection rod 46 drives the rotation of the protection bar 47. The rotation of the protection bar 47 releases the limit between the protection bar 47 and the L-shaped groove 48. After the limit between the protection bar 47 and the L-shaped groove 48 is released, manually pull the protection rod 46 to move towards the direction close to the T-shaped telescopic plate 43. The movement of the protection rod 46 towards the direction close to the T-shaped telescopic plate 43 drives the movement of the fixed rod 461. The movement of the fixed rod 461 drives the movement of the protection plate 45. The movement of the protection plate 45 squeezes the two release rods 44. The two release rods 44 move away from each other under the extrusion of the protection plate 45. The movement of the two release rods 44 away from each other drives the movement of the two switch boards 42. At the same time, the movement of the two release rods 44 away from each other drives the movement of the free ends of the two T-shaped telescopic plates 43. The movement of the free ends of the two T-shaped telescopic plates 43 releases the limit on the splicing block 2, enabling the splicing block 2 to be taken out from the interior of the placement frame 41, achieving the effect of facilitating the disassembly of the spliced railing 1.

[0033] When the present embodiment is working, during the splicing of the railing 1, when splicing the blocks 2, manually align the splicing blocks 2 to the surface of the switch board 42. Under the manual force, the splicing blocks 2 squeeze the two switch boards 42. The two switch boards 42 move away from each other under the extrusion of the splicing blocks 2, allowing the splicing blocks 2 to enter the interior of the placement frame 41. After the splicing blocks 2 enter the interior of the placement frame 41 and continue to move, they contact the free ends of the T-shaped telescopic plates 43 and squeeze the free ends of the T-shaped telescopic plates 43. The free ends of the two T-shaped telescopic plates 43 move away from each other under the extrusion of the splicing blocks 2, causing the splicing blocks 2 to continue to move into the interior of the placement frame 41. The splicing blocks 2 continue to move into the interior of the placement frame 41 and contact the elastic plate 51 and squeeze the elastic plate 51. The elastic plate 51 moves away from the switch board 42 under the extrusion of the splicing blocks 2, driving the groove block 55 to move. At the same time, the elastic plate 51 moves away from the switch board 42 and squeezes the elastic piece 53 to store energy.

After the limit between the protection bar 47 and the L-shaped groove 48 is released, manually pull the protection rod 46 to move towards the T-shaped telescopic plate 43. The movement of the protection rod 46 towards the T-shaped telescopic plate 43 drives the movement of the fixed rod 461. The movement of the fixed rod 461 drives the movement of the protection plate 45. The movement of the protection plate 45 squeezes the two release rods 44. The two release rods 44 move away from each other under the extrusion of the protection plate 45. The two release rods 44 moving away from each other drive the free ends of the two T-shaped telescopic plates 43 to move away from each other. The free ends of the two T-shaped telescopic plates 43 moving away from each other drive the telescopic rod 54 to move downward. The telescopic rod 54 moves downward and disengages from the contact with the elastic plate 51. After the elastic plate 51 disengages from the contact with the telescopic rod 54, under the action of the reset of the elastic piece 53, it quickly moves towards the switch board 42. The elastic plate 51 quickly moves towards the switch board 42 and pushes the splicing block 2 to move, accelerating the separation of the splicing block 2 from the placement frame 41. At the same time, the elastic plate 51 quickly moves towards the switch board 42 and pulls the soft rope 58 to drive the jet plate 57 to move downward. The jet plate 57 moves downward and squeezes the gas inside the jet frame 56 to spray towards the interior of the placement frame 41 through the jet orifice.

[0034] When the two railings 1 are opened, the railing 1 drives the connecting plate 69 to move. The movement of the connecting plate 69 pulls the winding rope 610 to open and drives the winding device 62 to rotate. The winding device 62 includes a fixed bracket, a rotating shaft and a winding wheel. After the railing 1 is opened to the designated position, manually rotate the control rod 65. The rotation of the control rod 65 releases the limit between the rectangular block 68 and the round block 67. After the limit between the rectangular block 68 and the round block 67 is released, the control rod 65 is pushed to move towards the winding device 62. The movement of the control rod 65 towards the winding device 62 contacts the fixed groove on the surface of the moving rod 64 to form a limit. The contact between the control rod 65 and the fixed groove on the surface of the moving rod 64 forms a limit so that the receiving rod 63 cannot move. The inability of the receiving rod 63 to move limits the winding device 62 so that the winding device 62 cannot rotate. When tightening the two railings 1, manually rotate the control rod 65. After the control rod 65 rotates and aligns the rectangular block 68 with the moving groove on the surface of the round block 67, pull the control rod 65 to move away from the winding device 62. The movement of the control rod 65 away from the winding device 62 releases the limit with the moving rod 64 so that the receiving rod 63 can move freely. Under the action of the scroll spring in the winding device 62, the winding device 62 rotates to pull the winding rope 610 to tighten. The tightening of the winding rope 610 drives the connecting plate 69 to move, and the movement of the connecting plate 69 drives the two railings 1 to tighten. At the same time, release the control rod 65. Under the elastic force of the No. 5 spring, the control rod 65 is driven to rotate. The rotation of the control rod 65 drives the rectangular block 68 to rotate, and the rotation of the rectangular block 68 restores the limit with the round block 67.
