[0001] This invention relates to the field of electromechanical engineering equipment technology, specifically to an anti-electric shock device for emergency repairs in electromechanical engineering. Background Technology
[0002] Mechatronics engineering is actually a general term for two majors: mechanical and electrical engineering. However, it is sometimes also used as an abbreviation for mechatronics engineering. Mechatronics engineering cultivates high-level application-oriented and technical talents with essential basic theoretical knowledge, specialized knowledge, and strong ability to engage in practical work in this professional field. These talents are well-rounded in terms of morality, intelligence, physical fitness, and aesthetics, and are adapted to the needs of the front line of production, construction, management, and service. Mechatronics is an interdisciplinary integration of multiple disciplines such as mechanics, electronics, optics, control, computer science, and information technology. Its development and progress depend on and promote the development and progress of related technologies.
[0003] When existing electromechanical engineering machinery malfunctions, it is necessary to use anti-electric shock devices to detect whether there is leakage in the machinery's casing or parts. However, electronic components can malfunction over time, which can affect the lifespan of the equipment. Therefore, a new technical solution needs to be designed to address this issue. Summary of the Invention
[0004] The purpose of this invention is to provide an anti-electric shock device for emergency repairs in electromechanical engineering, in order to solve the problem mentioned in the background art that when electromechanical engineering machinery malfunctions during use, it is necessary to use an anti-electric shock device to detect whether there is leakage in the outer casing or parts of the machinery. However, due to the fact that electronic components may malfunction after long-term use, the service life of the device may be affected.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an anti-electric shock device for emergency repairs in electromechanical engineering, comprising a fixing device and a voltage-reducing device. The fixing device includes a mounting box, contact pieces, a probe, and a top plate. A partition is welded to the middle of the bottom of the mounting box. The top plate is fixed to the top of the mounting box by bolts. An induction lamp and a knob are embedded in the top of the top plate. The contact pieces are embedded in the bottom of the mounting box. The probe is connected to the mounting box via a wire. The voltage-reducing device is located at the bottom of the mounting box. The voltage-reducing device includes an AC voltage-reducing appliance, a DC voltage-reducing transformer, a first card holder, a second card holder, a rotating column, and a crossbar. The rotating column is rotatably connected to the bottom of the mounting box. The AC voltage-reducing appliance is electrically connected to the first card holder. The DC voltage-reducing transformer is electrically connected to the second card holder. The crossbar is sleeved on the outer wall of the rotating column. A contact piece is embedded in the top and bottom of the end of the crossbar away from the rotating column. The induction lamp is connected to the second card holder via the crossbar.
[0006] In order to facilitate the mounting box being fixed to the arm, as a preferred embodiment of the electromechanical engineering emergency repair anti-electric shock device of the present invention, two elastic bands are inserted into the bottom of the mounting box.
[0007] To prevent leakage current from flowing directly into the body, as a preferred embodiment of the electromechanical engineering emergency repair anti-electric shock device of the present invention, the top of the probe is fixed with a handheld component by bolts. The handheld component includes a second rubber disc and a handheld rod, and the handheld rod is connected to the second rubber disc by bolts.
[0008] To prevent accidental contact between the hand and mechanical parts, as a preferred embodiment of the electromechanical engineering emergency repair anti-electric shock device of the present invention, a protective net is inserted into the top outer edge of the second rubber disc.
[0009] In order to facilitate the control of the length of the pulled-out wire so that the probe has enough room to move and contact the outer wall of the mechanical component, as a preferred embodiment of the electromechanical engineering emergency repair anti-electric shock device of the present invention, a winding reel is installed on the left side wall of the inner cavity of the mounting box, and the wire is wound around the outer side wall of the winding reel.
[0010] To prevent the probe from coming into contact with the leaking mechanical housing when placed horizontally, as a preferred embodiment of the electromechanical engineering emergency repair anti-electric shock device of the present invention, a first rubber disc is fitted onto the outer wall of the end of the probe away from the mounting box.
[0011] In order to increase the friction between the rotating column and the mounting box, as a preferred embodiment of the electromechanical engineering emergency repair anti-electric shock device of the present invention, the end of the rotating column near the mounting box is fitted with a rubber sleeve.
[0012] In order to ensure that the two circuits do not interfere with each other, as a preferred embodiment of the electromechanical engineering emergency repair anti-electric shock device of the present invention, a metal sheet is embedded at the bottom of the outer wall slot of the first card holder and a metal sheet is embedded at the top of the outer wall slot of the second card holder.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] The anti-electric shock device for emergency repair of electromechanical engineering is designed by installing a contact piece at the bottom of the mounting box, which comes into contact with the human skin. The mounting box can be strapped to the hand for easy carrying, making the human body part of the circuit conductor. When the probe is brought into contact with the outer shell of the electromechanical engineering machinery, the voltage flowing through the mounting box is below the safe voltage. At this point, the human body can directly determine whether the electromechanical engineering machinery has a leakage through touch. Since electronic components may malfunction after prolonged and repeated use, which may affect the detection of leakage, this structure uses the principle of electromagnetic induction to reduce the voltage below the safe voltage and makes the judgment through human touch, thereby effectively improving the service life of the device.
[0015] An AC step-down converter and a DC step-down converter are installed inside the mounting box. Both output voltages are below the safe voltage that the human body can withstand. The AC step-down converter is connected to the contact plate, while the DC step-down converter is connected to the sensor light. Usually, the DC step-down converter is used first to observe whether the sensor light is lit. If the ambient light is too strong to see whether the sensor light is lit or the sensor light is not lit, the AC step-down converter is used. In this way, the stability of the device is ensured by using two circuits. Attached Figure Description

Detailed Implementation
[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Please see Figure 1-4 The present invention provides a technical solution including a fixing device 100 and a pressure reducing device 200.
[0023] In this technical solution, an anti-electric shock device for emergency repair of electromechanical engineering is provided. The fixing device 100 includes a mounting box 110, a contact piece 120, a probe 130, and a top plate 150. A partition 112 is fused to the middle of the bottom of the inner cavity of the mounting box 110. The top plate 150 is fixed to the top of the mounting box 110 by bolts. An induction lamp 113 and a knob 151 are embedded in the top of the top plate 150. The contact piece 120 is embedded in the bottom of the mounting box 110. The probe 130 is connected to the mounting box 110 through a wire.
[0024] In this technical solution, the mounting box 110 is used to provide support points for the installation of various devices, the contact piece 120 forms a passage with the voltage reduction device 200 so that the arm feels numbness to determine whether the electromechanical engineering machinery has leaked electricity, the probe 130 is used to contact the outer wall of the electromechanical engineering machinery, and the top plate 150 is used to seal the inner cavity of the mounting box 110.
[0025] In this technical solution, the step-down device 200 is located at the bottom of the inner cavity of the mounting box 110. The step-down device 200 includes an AC step-down appliance 210, a DC step-down transformer 220, a first card holder 230, a second card holder 240, a rotating column 250, and a crossbar 260. The rotating column 250 is rotatably connected to the bottom of the inner cavity of the mounting box 110. The AC step-down appliance 210 is electrically connected to the first card holder 230, and the DC step-down transformer 220 is electrically connected to the second card holder 240. The crossbar 260 is sleeved on the outer wall of the rotating column 250. A contact piece 261 is embedded at the top and bottom of the end of the crossbar 260 away from the rotating column 250. The sensor lamp 113 is connected to the second card holder 240 through the crossbar 260.
[0026] In this technical solution, the AC step-down device 210 is used to convert the leakage voltage to below the safe AC voltage for the human body, the DC step-down device 220 is used to convert the leakage voltage to below the safe DC voltage for the human body, and the first card holder 230 and the second card holder 240 are used in conjunction with the rotating column 250 and the crossbar 260 to select the circuit to be connected.
[0027] In some technical solutions, reference Figure 1 The bottom of the mounting box 110 is connected to two elastic bands 111.
[0028] In this technical solution, the use of elastic band 111 allows the mounting box 110 to be securely tied to the arm for easy carrying, so that the contact piece 120 comes into contact with the skin.
[0029] In some technical solutions, reference Figure 1 The top of the probe 130 is fixed with a handpiece 140 by bolts. The handpiece 140 includes a second rubber disc 141 and a hand handle 142. The hand handle 142 is connected to the second rubber disc 141 by bolts.
[0030] In this technical solution, both the second rubber disc 141 and the hand lever 142 are made of insulating material. Therefore, the combined use of the second rubber disc 141 and the hand lever 142 allows the hand to easily hold the probe 130 and move it to the mechanical housing wall to be inspected.
[0031] In some technical solutions, reference Figure 1 A protective net 1411 is inserted into the top outer edge of the second rubber disc 141.
[0032] In this technical solution, the use of protective net 1411 can protect the hands and prevent the hands from contacting the outer wall of external mechanical parts to prevent electric shock. The material used for protective net 1411 is insulating material.
[0033] In some technical solutions, reference Figure 2 A winding reel 114 is installed on the left side wall of the inner cavity of the mounting box 110, and the wire is wound around the outer side wall of the winding reel 114.
[0034] In this technical solution, the use of the reel 114 allows for adjustment of the wire pull-out length, enabling inspection of the outer casing of parts deep within the machinery.
[0035] In some technical solutions, reference Figure 1 The outer side wall of the end of the probe 130 away from the mounting box 110 is fitted with a first rubber disc 131.
[0036] In this technical solution, the use of the first rubber disc 131 can prevent the end of the probe 130 from contacting the external metal casing when the probe 130 is placed horizontally.
[0037] In some technical solutions, reference Figure 4 A rubber sleeve 251 is fitted onto one end of the rotating column 250 near the mounting box 110.
[0038] In this technical solution, the use of rubber sleeve 251 can increase the rotational friction between rotating column 250 and mounting box 110, so that when crossbar 260 is stuck in first card seat 230 or second card seat 240, crossbar 260 will not easily disengage from first card seat 230 or second card seat 240.
[0039] In some technical solutions, reference Figure 2-3 A metal sheet is embedded at the bottom of the outer wall slot of the first card holder 230, and a metal sheet is embedded at the top of the outer wall slot of the second card holder 240.
[0040] In this technical solution, the corresponding circuit is connected when the crossbar 260 contacts the first card holder 230 or the second card holder 240.
[0041] Working principle: Insert the arm between the elastic band 111 and the mounting box 110, fixing the mounting box 110 to the arm and making the contact piece 120 contact the skin of the arm. At this time, the other hand holds the handle 142 and the end of the probe 130 contacts the outer wall of the electromechanical engineering machinery. At this time, the knob 151 is initially in the position of the crossbar 260 inserted into the second card slot 240. A DC circuit is used. If there is no leakage, the sensor light 113 will not light up. If there is a leakage, the sensor light 113 will light up. If the ambient light is strong and affects the judgment of the brightness of the sensor light 113, rotate the knob 151. The knob 151 drives the rotating column 250 to rotate, so that the crossbar 260 is inserted into the first card slot 230, connecting the AC circuit. If there is no leakage, there is no electric shock in the arm. If there is a leakage, there is an electric shock in the arm, thus effectively protecting the worker from the danger of electric shock.
