Description

Technical Field

[0001] This invention relates to the field of safety devices for power construction, specifically a safety power-off device for power construction management. Background Technology

[0002] Safety power-off devices for power construction management refer to a special equipment or system used in the construction of power projects to ensure operational safety. Its core function is to forcibly cut off the power supply to the construction area through physical isolation, electrical interlocking or intelligent control, so as to prevent accidental electric shock accidents caused by misoperation, equipment failure or environmental factors. It is an indispensable protective measure in the power construction safety management system. However, during current power construction safety operations, when power is cut off, construction workers cannot keep a close eye on the switch while installing or maintaining equipment. If the switch is accidentally turned on by other personnel, it can pose a safety hazard to the construction workers. At the same time, when traditional power equipment is operated to disconnect or reconnect, the instantaneous current characteristics of the circuit can easily generate electric sparks, which may not only cause secondary risks such as fires and explosions, but also cause physical injuries to construction workers who are operating at close range.

[0003] Therefore, a safety power-off device for power construction management is needed to improve the above-mentioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a safety power-off device for power construction management, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A safety power-off device for power construction management includes a mounting housing, a fixing component installed on the inner wall of the mounting housing, a connecting groove provided on the side wall of the mounting housing, wherein multiple sets of connecting grooves are provided and are respectively located on the side wall of the mounting housing, and a power-off push-pull component is embedded in the outer wall of the mounting housing. A face recognition camera is installed on the outer wall of the mounting housing. A human body sensing sensor is installed on the outer wall of the mounting housing. A handle is installed on the outer wall of the mounting housing. A control panel is installed on one side of the handle and on the outer wall of the mounting housing. A magnetic base is embedded on one side of the control panel and on the outer wall of the mounting housing. A wireless controller is plugged into the inner wall of the magnetic base.

[0006] As a preferred embodiment of the present invention, the fixing component includes an inner housing, which is mounted on the inner wall of the mounting housing. A rotating shaft is rotatably connected to the inner wall of the inner housing, and one end of the rotating shaft passes through the inner housing and the mounting housing in sequence and extends to the outer wall of the mounting housing where a drive motor is mounted.

[0007] As a preferred embodiment of the present invention, the connection between the rotating shaft and the mounting housing is a rotatable connection, and a drive gear is installed on the inner cavity of the inner housing and on the outer wall of the rotating shaft. A sliding groove and a limiting groove are provided on the opposite outer walls of the inner housing.

[0008] As a preferred embodiment of the present invention, a limiting rack is slidably connected to the inner wall of the sliding groove, one end of the limiting rack is slidably connected to the inner wall of the limiting groove, and a driving gear is meshed on the outer wall of the limiting rack. Multiple sets of limiting racks are provided and are respectively located on the outer wall of the driving gear, and the multiple sets of limiting racks are interleaved with each other.

[0009] As a preferred embodiment of the present invention, the other end of the limiting rack passes through the connecting groove and extends to the outer wall of the connecting groove to be fitted with a clamping and fixing plate. A fixing sleeve is embedded in the outer wall of the mounting housing. A limiting guide rod is slidably connected to the inner wall of the fixing sleeve. One end of the limiting guide rod is connected to the clamping and fixing plate.

[0010] As a preferred embodiment of the present invention, the power-off push-pull assembly includes a mounting base, one end of which is plugged into and installed on the outer wall of the mounting housing. Limiting rods are symmetrically installed on the outer wall of the mounting base, and one end of each limiting rod is fitted with a mounting frame. Multiple sets of limiting rods are provided and are respectively located on the outer wall of the mounting frame.

[0011] As a preferred embodiment of the present invention, a limit spring is installed on the inner wall of the mounting frame, wherein multiple sets of limit springs are provided and are respectively located on the outer wall of the mounting frame, and one end of the limit spring is connected to the outer wall of the mounting base. An electrically controlled cylinder is arranged on the inner wall of the mounting frame from left to right, and a push-pull clamp is installed on one end of the electrically controlled cylinder, and the push-pull clamp is located on one side of the mounting housing.

[0012] As a preferred embodiment of the present invention, multiple sets of sliding grooves and limiting grooves are provided and are respectively located on the opposite outer walls of the inner shell, and multiple sets of fixing sleeves are provided and are respectively located on the outer walls of the mounting shell.

[0013] As a preferred embodiment of the present invention, the wireless controller and the control panel are connected wirelessly, and the control panel is electrically connected to a face recognition camera, a human body sensing sensor, a drive motor and an electric cylinder via wires.

[0014] With the above technical solution, the mounting base is inserted into the inner wall of the mounting housing. Since the mounting frame is fixed to the outer wall of the mounting base by the limiting spring and the limiting rod, one end of the limiting spring applies a pushing force to the mounting frame, thereby causing the mounting frame to move laterally with the limiting rod, thus fixing the push-pull clamp.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, by clamping the push-pull clamp onto the push rod of the circuit breaker, and then clamping the mounting base into the inner wall of the mounting housing, one end of the limiting spring applies a pushing force to the mounting frame, thereby causing the mounting frame to move the limiting rod laterally, thus further fixing the push-pull clamp. Then, simply turn on the control panel switch to make the control panel control the electric cylinder to operate, which will cause one end of the electric cylinder to push the push-pull clamp to move longitudinally, and the push-pull clamp will drive the circuit breaker push rod to disconnect the circuit. This helps to solve the problem that the current characteristics at the moment of circuit opening and closing are prone to generating electric sparks, which may not only cause secondary risks such as fire and explosion, but also cause physical injury to construction personnel operating at close range.

[0016] 2. In this invention, a facial recognition camera performs facial recognition on the operator. Simultaneously, the electrical signal generated by the facial recognition camera based on the recognition data is transmitted via wires to the control panel for storage. A human body sensor detects people in front of the device; when someone approaches, the sensor generates an electrical signal, which is transmitted via wires to the control panel. The control panel then controls the facial recognition camera to perform facial recognition on the operator. The control panel analyzes the generated and stored data. The construction worker removes the wireless controller from its magnetic base and carries it on their person. Simultaneously, the control panel wirelessly transmits signals to the wireless controller, allowing the construction worker to remotely monitor the equipment. This effectively solves the problem of construction workers not being able to constantly monitor the power switch during equipment installation, maintenance, and other operations.

[0017] 3. In this invention, after unlocking via facial recognition, the control panel switch is turned on, causing the drive shaft of the drive motor to rotate, which in turn causes one end of the rotating shaft to drive the drive gear to rotate. The drive gear meshes with and drives the limiting rack, causing the limiting rack to move laterally on the inner wall of the sliding groove. One end of the limiting rack pushes the clamping fixing plate outward, causing the clamping fixing plate to drive the limiting guide rod outward. At the same time, multiple sets of limiting racks on the outer wall of the drive gear synchronously push the clamping fixing plate outward, so that the clamping fixing plate is fixed against the inner wall of the power cabinet. The mounting housing completely shields the power switch to prevent accidental operation, thus helping to solve the problem of accidental power-on by other personnel, which could pose a safety hazard to construction workers.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present invention will be more thorough and complete.

[0022] For examples, please refer to Figure 1-7 The present invention provides a technical solution: A safety power-off device for power construction management includes a mounting housing 1, a fixing component 2 installed on the inner wall of the mounting housing 1, a connecting groove 3 opened on the side wall of the mounting housing 1, wherein multiple sets of connecting grooves 3 are provided and are respectively located on the side wall of the mounting housing 1, and a power-off push-pull component 4 is embedded in the outer wall of the mounting housing 1. A face recognition camera 5 is installed on the outer wall of the mounting housing 1. A human body sensing sensor 6 is installed on the outer wall of the mounting housing 1. A handle 7 is installed on the outer wall of the mounting housing 1. A control panel 8 is installed on one side of the handle 7 and on the outer wall of the mounting housing 1. A magnetic base 9 is embedded on one side of the control panel 8 and on the outer wall of the mounting housing 1. A wireless controller 10 is plugged into the inner wall of the magnetic base 9.

[0023] In this embodiment, the fixing component 2 includes an inner housing 201, which is mounted on the inner wall of the mounting housing 1. A rotating shaft 202 is rotatably connected to the inner wall of the inner housing 201. One end of the rotating shaft 202 passes through the inner housing 201 and the mounting housing 1 in sequence and extends to the outer wall of the mounting housing 1, where a drive motor 203 is mounted. The rotating shaft 202 and the mounting housing 1 are connected by a rotatable connection. A drive gear 204 is mounted in the inner cavity of the inner housing 201 and on the outer wall of the rotating shaft 202. A sliding groove 205 and a limiting groove 206 are formed on the opposite outer walls of the inner housing 201. A sliding groove 205 and a limiting groove 206 are slidably connected on the inner wall of the sliding groove 205. The limiting rack 207 has one end slidably connected to the inner wall of the limiting groove 206, and a drive gear 204 meshing with the outer wall of the limiting rack 207. Multiple sets of limiting racks 207 are provided and are located on the outer wall of the drive gear 204, and the multiple sets of limiting racks 207 are interleaved with each other. The other end of the limiting rack 207 passes through the connecting groove 3 and extends to the outer wall of the connecting groove 3 where a clamping and fixing plate 208 is installed. A fixing sleeve 209 is embedded in the outer wall of the mounting housing 1. A limiting guide rod 210 is slidably connected to the inner wall of the fixing sleeve 209, and one end of the limiting guide rod 210 is connected to the clamping and fixing plate 208.

[0024] In this embodiment, the power-off push-pull assembly 4 includes a mounting base 401. One end of the mounting base 401 is plugged into and installed on the outer wall of the mounting housing 1. Limiting rods 402 are symmetrically installed on the outer wall of the mounting base 401. One end of the limiting rods 402 is installed with a mounting frame 403. Multiple sets of limiting rods 402 are provided and are respectively located on the outer wall of the mounting frame 403. Limiting springs 404 are installed on the inner wall of the mounting frame 403. Multiple sets of limiting springs 404 are provided and are respectively located on the outer wall of the mounting frame 403. One end of the limiting springs 404 is connected to the outer wall of the mounting base 401. An electrically controlled cylinder 405 is provided from left to right on the inner wall of the mounting frame 403. A push-pull clamp 406 is installed on one end of the electrically controlled cylinder 405. The push-pull clamp 406 is located on one side of the mounting housing 1.

[0025] Multiple sets of sliding grooves 205 and limiting grooves 206 are provided and are respectively located on the opposite outer walls of the inner housing 201, and multiple sets of fixing sleeves 209 are provided and are respectively located on the outer walls of the mounting housing 1.

[0026] Based on the above structural features and connection relationship, the mounting base 401 is inserted into the inner wall of the mounting housing 1. Since the mounting frame 403 is fixed to the outer wall of the mounting base 401 by the limiting spring 404 and the limiting rod 402, one end of the limiting spring 404 applies a pushing force to the mounting frame 403, thereby causing the mounting frame 403 to drive the limiting rod 402 to move laterally, thereby further fixing the push-pull clamp 406. The wireless controller 10 and the control panel 8 are connected wirelessly. The control panel 8 is electrically connected to the face recognition camera 5, the human body sensing sensor 6, the drive motor 203 and the electric cylinder 405 via wires, which powers the device and allows the control panel 8 to control the face recognition camera 5, the human body sensing sensor 6, the drive motor 203 and the electric cylinder 405 to operate.

[0027] The workflow of this invention is as follows: When the safety power-off device for power construction management designed in this solution is in operation, the wireless controller 10 and the control panel 8 are connected wirelessly. The control panel 8 is electrically connected to the face recognition camera 5, the human body sensing sensor 6, the drive motor 203, and the electric cylinder 405 via wires. This power-off enables the device to be powered on, and the control panel 8 then controls the face recognition camera 5, the human body sensing sensor 6, the drive motor 203, and the electric cylinder 405 to operate. An electrically controlled cylinder 405 is installed on the inner wall of the mounting frame 403 from left to right. A push-pull clamp 406 is installed at one end of the cylinder 405. Under the action of the push-pull clamp 406 located on one side of the mounting housing 1, the push-pull clamp 406 is secured to the push rod of the switch. Then, the mounting base 401 is inserted into the inner wall of the mounting housing 1. Since the mounting frame 403 is fixed to the outer wall of the mounting base 401 by a limiting spring 404 and a limiting rod 402, one end of the limiting spring 404 applies a pushing force to the mounting frame 403, causing the mounting frame 403 to move laterally along the limiting rod 402, thereby... The push-pull clamp 406 is further fixed. Then, simply turn on the switch of the control panel 8 so that the control panel 8 controls the electric cylinder 405 to operate. This will cause one end of the electric cylinder 405 to push the push-pull clamp 406 to move longitudinally. The push-pull clamp 406 will then drive the circuit breaker push rod to disconnect the circuit. Due to the elastic action of the limit spring 404, the push-pull clamp 406 will be stuck on the outer wall of the circuit breaker push rod. This helps to solve the problem that the current characteristics at the moment of circuit switching are prone to generating electric sparks, which may not only cause secondary risks such as fire and explosion, but also cause physical injury to construction personnel operating at close range. With a face recognition camera 5 mounted on the outer wall of the housing 1, and a human body sensor 6 also mounted on the outer wall of the housing 1, simply turning on the control panel 8 will cause the control panel 8 to operate the face recognition camera 5 and the human body sensor 6. This allows the face recognition camera 5 to perform face recognition on the operator, and the electrical signal generated by the face recognition camera 5 based on the recognition data is transmitted through wires to the control panel 8 for storage. Meanwhile, the human body sensor 6 detects people in front of the device. When someone approaches, the human body sensor 6 generates an electrical signal, which is transmitted through wires to the control panel 8. The control panel 8 then controls the face recognition camera 5 to perform face recognition on the operator, and simultaneously processes the generated data. The data stored is analyzed. A handle 7 is installed on the outer wall of the mounting housing 1. A control panel 8 is installed on one side of the handle 7 and on the outer wall of the mounting housing 1. A magnetic base 9 is embedded on one side of the control panel 8 and on the outer wall of the mounting housing 1. A wireless controller 10 is plugged into the inner wall of the magnetic base 9. The wireless controller 10 and the control panel 8 are connected wirelessly. When the construction personnel pull the wireless controller 10 out of the magnetic base 9, they can carry the wireless controller 10 on their body. At the same time, the control panel 8 transmits signals to the wireless controller 10 through the wireless connection, so that the construction personnel can remotely view the equipment. This helps to solve the problem that the construction personnel cannot keep an eye on the power switch in real time when they need to install, repair or perform other operations on the equipment. By holding the handle 7, the operator places the mounting housing 1 on the inner wall of the power cabinet. The mounting housing 1 is positioned to one side of the power switch. After the power-off push-pull assembly 4 is fixed, the control panel 8 can only be turned on after facial recognition unlocking. This causes the control panel 8 to control the drive motor 203, which in turn drives the rotating shaft 202 to rotate. The rotating shaft 202 rotates on the outer wall of the mounting housing 1, causing one end of the rotating shaft 202 to drive the drive gear 204 to rotate. The drive gear 204 is mounted on the outer wall of the rotating shaft 202. The inner housing 201 has a sliding groove 205 and a limiting groove 206 on its opposite outer wall. A limiting rack 207 is slidably connected to the inner wall of the sliding groove 205. One end of the limiting rack 207 is slidably connected to the inner wall of the limiting groove 206. The drive gear 204 is meshed on the outer wall of the limiting rack 207. The limiting rack 207 is designed to... Multiple sets of limiting racks 207, located on the outer wall of the drive gear 204 and interlocked, cause the drive gear 204 to mesh with and drive the limiting racks 207, allowing the limiting racks 207 to move laterally on the inner wall of the sliding groove 205. This causes one end of the limiting rack 207 to slide on the inner wall of the connecting groove 3, pushing the clamping plate 208 outward. As the clamping plate 208 moves, it causes the limiting guide rod 210 to move outward. Simultaneously, the multiple sets of limiting racks 207 on the outer wall of the drive gear 204 push the clamping plate 208 outward, fixing it against the inner wall of the power cabinet. The mounting housing 1 completely shields the switch to prevent accidental operation, thus mitigating the safety hazards posed to construction workers by accidental power-on by other personnel.
