[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0038] Example 1, such as Figure 1-10 As shown, a safety guardrail for power construction projects includes a base 100, a fence 200 that can be plugged into the base 100, and a crossbeam 300 that can be plugged into the top of the fence.

[0039] The base 100 is a U-shaped groove made of stainless steel with plug-in structures at both ends. The plug-in structures include a socket 110 integrally formed with the base, a rectangular insertion hole 111 opening on the upper surface of the socket, a wedge-shaped pressure block 120 with a pressing end face 121, and a compression spring 130 acting between the wedge-shaped pressure block and the socket. The pressing end face 121 of the wedge-shaped pressure block 120 is a rectangular plane, used to increase the contact area with the object being pressed, enhancing the stability of the object. The wedge-shaped pressure block 120 has a hollow cavity inside to accommodate the compression spring 130.

[0040] The socket 110 is also provided with a rectangular receiving chamber that is perpendicular to the rectangular socket 111. The width of the rectangular receiving chamber is greater than the width of the rectangular socket 111. One end of the rectangular receiving chamber opens at the middle position of the rectangular socket 111, and the other end of the rectangular receiving chamber, away from the rectangular socket, opens on one side wall of the socket 110. A pressure cover 112 is fixed to the side wall with bolts. The wedge-shaped pressure block 120 is placed in the rectangular receiving chamber and can slide along the inner wall of the rectangular receiving chamber. One end of the compression spring 130 presses against the inner wall of the hollow cavity of the wedge-shaped pressure block 120, and the other end presses against the pressure cover 112.

[0041] The outer end faces of the two sockets 110 at both ends of the base 100 are respectively provided with protrusions 114 and concave grooves 115 that can engage with each other. The side wall of the protrusion 114 is provided with a through first pin hole 116, and the side wall of the concave groove 115 is provided with a through second pin hole 117 at a corresponding position. When multiple bases are spliced, the protrusions 114 are inserted into the concave grooves 115 of the adjacent bases, the first pin hole 116 and the second pin hole 117 are aligned, and the adjacent bases are quickly spliced ​​by inserting and locking with a pin 140. For power construction projects with long construction periods, bolts can also be used instead of pins and inserted into the first pin hole 116 and the second pin hole 117, and the bolts can be tightened with nuts to make the connection between adjacent bases more stable.

[0042] Two height adjustment screws 118 are provided on each of the two sockets 110 at both ends of the base 100. The base 100 can be leveled by rotating the height adjustment screws 118.

[0043] The fence 200 includes two stainless steel rectangular tubes 210 and a mesh made of stainless steel chains fixedly connected between the two stainless steel rectangular tubes, with a mesh spacing of no more than 15cm. The outer dimensions of the cross-section of the two rectangular tubes 210 are clearance-fitted with the opening dimensions of the two rectangular insertion holes 111 at both ends of the base 100, with a clearance of 0.1mm-0.3mm. After the fence 200 is unfolded, its two rectangular tubes 210 can be inserted into the two rectangular insertion holes 111 at both ends of the base 100, and a stable connection with the base 100 is achieved under the pressing action of the pressing end face 121 of the wedge-shaped pressure block 120.

[0044] The crossbeam 300 is a stainless steel rectangular tube with rectangular sleeves 310 at both ends. The sleeves have an upper insertion end with a hollow upper opening and a lower insertion end with a closed bottom. The outer dimensions of the cross-section of the lower insertion end of the rectangular sleeve are in clearance fit with the opening dimensions of the two rectangular tubes 210, with a clearance of 0.05mm-0.2mm. The lower insertion ends of the rectangular sleeves at both ends of the crossbeam 300 can be inserted into the upper openings of the two rectangular tubes 210, thereby fixing the two rectangular tubes of the fence 200 from the top.

[0045] Two adjacent crossbeams are connected and fixed using stainless steel U-shaped clips 320. The U-shaped clips 320 can be inserted into the upper inserted end cavity of the rectangular sleeve 310 between two adjacent crossbeams 300 through the upper inserted end opening. After insertion, the outer surface of the U-shaped clips 320 fits against the inner surface of the upper inserted end cavity of the rectangular sleeve 310, thereby achieving the purpose of connecting and fixing the two adjacent crossbeams.

[0046] Each of the rectangular sleeves 310 at both ends of the crossbeam 300 has two through holes on its sidewall. These two through holes are located at the middle of the upper inserted end cavity and the middle of the lower inserted end of the rectangular sleeve 310, respectively. Correspondingly, the U-shaped buckle 320 and the two rectangular tubes 210 have through holes of the same size at corresponding positions on their sidewalls. For power construction projects with long construction periods, bolts can be inserted into the corresponding through holes and tightened with nuts, making the connection between the U-shaped buckle 320 and the two rectangular tubes of the fence connected and fixed by the crossbeams more secure.

[0047] The present invention provides a safety guardrail for power construction projects, which is also equipped with an intelligent sound and light alarm system, including a warning light 410 with an integrated buzzer and a solar panel 450 that are bolted to the top of the crossbeam 300, a reflective marking tape 420 that is pasted on the side wall of the crossbeam 300, a pressure sensor 430 that is set on a fixed platform 211 with a through hole in the cavity of the rectangular tube 210 of the guardrail, an angle sensor 440 that is fixed to the inner wall of the cavity of the rectangular tube 210, and a lithium battery charging unit 460 that is bolted to the U-shaped groove of the base.

[0048] The warning light 410 is a red and yellow LED light. Under normal circumstances, it flashes yellow to alert personnel, and in an emergency, it can flash red to indicate a warning. The lithium battery charging unit 460 can be powered by the solar panel 450, charged by mains power, or charged by the vehicle battery.

[0049] After the lower insertion ends of the rectangular sleeves 310 at both ends of the crossbeam 300 are inserted into the rectangular tube 210 of the fence, the bottom of the lower insertion end of the rectangular sleeve 310 contacts the top surface of the pressure sensor 430; the signals of the pressure sensor 430 and the tilt sensor 440 are linked with the alarm switch of the warning light 410.

[0050] When the external pressure on the crossbeam 300 exceeds 8Kg, the pressure sensor 430 is triggered to turn on the alarm switch of the warning light 410. The warning light 410 changes from flashing yellow to flashing red, and at the same time the buzzer sounds an alarm.

[0051] When the tilt angle of the fence 200 exceeds 20°, the tilt sensor 440 is triggered, activating the alarm switch of the warning light 410. The warning light 410 changes from flashing yellow to flashing red, and at the same time, the buzzer sounds an alarm.

[0052] The present invention discloses a method for using a safety guardrail in power construction projects, comprising the following steps.

[0053] When not in use, the fence 200 is placed in the U-shaped groove of the base 100, and the lower insertion ends of the rectangular sleeves 310 at both ends of the crossbeam 300 are inserted into the two rectangular holes 111 of the base 100.

[0054] In use, remove the fence 200 and crossbeam 300 from the U-shaped groove of the base 100, splice the multiple bases 100 together with convex and concave joints and fix them with pins or bolts inserted into the first pin hole 116 and the second pin hole 117, and adjust the height adjustment screw 118 to keep each base in the same horizontal position.

[0055] Unfold the fence 200 and insert the fence rectangular tubes 210 one by one into the two rectangular holes 111 at both ends of the base 100; insert the lower insertion ends of the rectangular sleeves 310 at both ends of the crossbeam 300 into the upper openings of the two rectangular tubes 210; insert the U-shaped buckle 320 into the cavity of the upper insertion end of the adjacent rectangular sleeves 310 of the two adjacent crossbeams 300.

[0056] The warning light 410 and solar panel 450 are bolted to the top of the crossbeam 300, the charging unit 460 is bolted to the U-shaped groove of the base 100, and the electrical components are connected with wires.

[0057] Fill the U-shaped grooves of each base with sand and gravel to increase the stability of the base.

[0058] Under normal circumstances, warning light 410 remains flashing yellow.

[0059] When the external pressure on the crossbeam 300 exceeds 8Kg, the pressure sensor 430 is triggered to turn on the alarm switch of the warning light 410. The warning light 410 changes from flashing yellow to flashing red, and at the same time the buzzer sounds an alarm.

[0060] When the tilt angle of the fence 200 exceeds 20°, the tilt sensor 440 is triggered to turn on the alarm switch of the warning light 410. The warning light 410 changes from flashing yellow to flashing red, and at the same time, the buzzer sounds an alarm.

[0061] Example 2: A safety guardrail for power construction projects. The base, fence, crossbeam and U-shaped buckle are all made of aluminum alloy, and the rest of the structure is the same as in Example 1.

[0062] Example 3: A safety guardrail for power construction projects. The guardrail is made of nylon mesh with a mesh spacing of no more than 10cm. The rest of the structure is the same as in Example 2. The safety guardrail in this example is lighter and more convenient, and is suitable for temporary power projects with a construction period of one working day.
