DETAILED DESCRIPTION

[0040] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0041] like Figure 1-10As shown, in this embodiment, an auxiliary anti-electric shock device for power maintenance is provided, which is mainly composed of a traction component 1, an anchor component 2 and an alarm component 3. The traction component 1 is installed on the top of the anchor component 2, and the anchor component 2 is used for anchoring. The alarm component 3 is wirelessly connected to the traction component 1. The alarm component 3 is carried by the construction personnel and is used to detect whether it is close to the live equipment. Specifically, the alarm component 3 in this embodiment is a commercially available near-electric alarm. The brand of the near-electric alarm is Dong Xiaoliu and the model is YJ-AM. Its working principle has been widely used in the market. For details, please refer to the commercially available near-electric alarm, which will not be repeated here. Of course, in order to realize the wireless connection between the alarm component 3 and the traction component 1 in this embodiment, it is also necessary to add a communication module so that it can establish a wireless signal connection with the traction component 1, so as to immediately feed back the alarm signal to the traction component 1.

[0042] Specifically, the traction assembly 1 in this embodiment further comprises a housing 101 disposed on the top of the anchor assembly 2, and a rope-releasing mechanism and a braking mechanism disposed in the housing 101. A traction safety rope is wound on the rope-releasing mechanism, and one end of the traction safety rope passes through the top of the housing 101 and is used to be buckled on the construction worker. The braking mechanism can brake the rope-releasing mechanism when the construction worker approaches the live equipment to limit the continued release of the traction safety rope.

[0043] Specifically, the rope-releasing mechanism in this embodiment includes a main shaft 102 and a secondary shaft 106 which are rotatably mounted inside the housing 101, respectively. The main shaft 102 and the secondary shaft 106 are aligned transversely and distributed inside the housing 101. A driving gear 104 and a reel 105 are fixedly provided on the main shaft 102. The traction safety rope is wound on the reel 105. A brake gear 107 and a driven gear 109 are fixedly provided on the secondary shaft 106, and the driven gear 109 is meshed with the driving gear 104. When the construction workers bind the traction safety rope for construction, the reel 105 rotates and gradually releases the traction safety rope, and at the same time, the main shaft 102 and the driving gear 104 will rotate together, and the driven gear 109 is driven to rotate by the driving gear 104 through meshing, so that the secondary shaft 106 and the brake gear 107 can also rotate along. When construction workers approach live equipment, the braking mechanism can brake the braking gear 107, limiting the rotation of the braking gear 107. Through the above-mentioned transmission matching relationship, the rotation of the reel 105 is also limited, thereby limiting the continued release of the traction safety rope, and ultimately limiting the continued forward movement of the construction workers' bodies, thereby ensuring safety.

[0044] Specifically, the braking mechanism in this embodiment includes a slide groove 110 fixed on the top of the inner wall of the shell 101 and an electric cylinder 116 fixed on one side of the inner wall of the shell 101. A slide rail 111 is also slidably engaged in the slide groove 110. The slide rail 111 and the slide groove 110 are slidably engaged through a T-shaped block groove. A moving rod frame 112 is also fixed to the bottom of the slide rail 111. The moving rod frame 112 is an inverted U-shaped structure, and the output end of the electric cylinder 116 is fixed to the moving rod frame 112. At the same time, a tongue 117 that matches the tooth gap of the brake gear 107 is provided at the bottom end of one side of the moving rod frame 112. During normal use, the latch 117 is disengaged from the brake gear 107 and will not affect the rope release. When construction workers approach live equipment, the output end of the electric cylinder 116 can extend, thereby driving the moving rod frame 112 to move and allowing the latch 117 to be stuck in the tooth gap of the brake gear 107, thereby completing the braking of the brake gear 107.

[0045] In order to quickly and conveniently recover the traction safety rope, a first bevel gear 103 is fixedly arranged on the main shaft 102 in this embodiment, and a motor 113 is installed at the bottom end of the side of the mobile rod frame 112 away from the latch 117, and a second bevel gear 114 is installed on the output end of the motor 113, and the second bevel gear 114 is meshed with the first bevel gear 103. When the traction safety rope needs to be recovered, the motor 113 is used to drive the second bevel gear 114 to rotate, and then drive the first bevel gear 103 to rotate and reverse the reel 105, thereby realizing the rapid recovery of the traction safety rope.

[0046] In order to further ensure safety and avoid entanglement of the traction safety rope, a friction wheel 108 is fixed on the secondary shaft 106 of this embodiment, and the friction wheel 108 is located between the brake gear 107 and the driven gear 109. A friction plate 115 is also provided on the mobile rod frame 112, and the friction plate 115 is tightly matched with the friction wheel 108. In this way, when the reel 105 rotates to release the rope, it can play a damping effect, so that when the traction safety rope is pulled out by the body of the construction worker, it will not be pulled out too much due to inertia, which effectively ensures safety, and also avoids the traction safety rope from being entangled with each other, making it smoother to use.

[0047] Specifically, the traction component 1 in this embodiment further includes a main battery power supply 118 and a main processor 119 disposed in the housing 101, wherein the main battery power supply 118 is used for power supply, and the main processor 119 is electrically connected to the motor 113 and the electric cylinder 116, and the main processor 119 is wirelessly connected to the alarm component 3. When the alarm component 3 approaches the live equipment, the alarm component 3 feeds back the sensing signal to the main processor 119, and the main processor 119 then instructs the electric cylinder 116 to extend, thereby completing the braking.

[0048] Specifically, the anchoring assembly 2 in this embodiment includes a base 201, a rotating shaft 202 is rotatably arranged in the center of the base 201, two first strong magnets 203 are symmetrically arranged outside the rotating shaft 202, and two second strong magnets 204 are symmetrically arranged inside the base 201, and the two second strong magnets 204 are located above the rotating shaft 202. When the rotating shaft 202 rotates to drive the two first strong magnets 203 to rotate, the magnetic attraction ability of the anchoring assembly 2 can be realized by superposition or offset of the magnetic field of the first strong magnet 203 and the magnetic field of the second strong magnet 204. The specific working principle can be referred to the commercially available permanent magnetic lifting suction cup, so it will not be described in detail. Of course, in order to facilitate the adjustment of the anchoring, a worm gear 205 is further provided at one end of the rotating shaft 202 of the present embodiment, and a worm 206 is also rotatably installed at one end of the base 201. The bottom of the worm 206 extends into the interior of the base 201 and meshes with the worm gear 205. At the same time, a rotating handle 207 is fixed to the top of the worm 206. In this way, by rotating the rotating handle 207, the worm 206 and the worm gear 205 can be driven to rotate, thereby driving the rotating shaft 202 to rotate. When the two first strong magnets 203 rotate to overlap with the magnetic field of the second strong magnet 204, a huge magnetic attraction effect appears at the bottom of the anchoring assembly 2, thereby achieving the anchoring and tightening effect.

[0049] This embodiment also provides a method for using the above-mentioned anti-electric shock device, and the specific steps of the method are as follows:

[0050] Step 1: Place the assembly of the traction component 1 and the anchoring component 2 on the surface of the object to be anchored, specifically, the surface of the object that can be strongly magnetically adsorbed;

[0051] Step 2: Turn the rotating handle 207 to drive the worm 206 and the worm wheel 205 to rotate, and drive the rotating shaft 202 to rotate until the two first strong magnets 203 rotate to overlap with the magnetic field of the second strong magnet 204, so that the combination of the traction component 1 and the anchoring component 2 can be fastened to the surface of the object to achieve anchoring;

[0052] Step 3: One end of the traction safety rope wound on the reel 105 is connected to the body of the construction worker through a ring buckle, and the construction worker carries the alarm component 3 with him, and ensures that a wireless signal connection is established between the alarm component 3 and the main processor 119 inside the traction component 1;

[0053] Step 4: When the construction workers approach the live equipment, the induction circuit inside the alarm component 3 immediately senses the existence of the electric field of the live equipment and immediately feeds back the induction signal to the main processor 119 inside the traction component 1. The main processor 119 then instructs the electric cylinder 116 to extend, thereby driving the moving rod frame 112 to move and causing the latch 117 to engage in the tooth gap of the brake gear 107 to complete the braking of the brake gear 107, thereby limiting the continued release of the traction safety rope and the continued forward movement of the construction workers' bodies, further achieving the purpose of preventing electric shock.
