[0001] The present invention relates to the technical field of power auxiliary equipment, and in particular to a wireless electromagnetic on-off system. Background Art

[0002] The distribution cabinet is a common cabinet in the power industry. The front surface of the distribution cabinet is often equipped with several switches for controlling the operation of the distribution cabinet. Most of the switches are pressed, and the most common ones are buttons. By pressing the button, the corresponding circuit inside the distribution cabinet can be connected, and by pressing it again, the corresponding circuit inside the distribution cabinet can be disconnected.

DETAILED DESCRIPTION

[0024] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] Example 1 The present invention provides a wireless electromagnetic suction on-off system, referring to Figure 1 , including: The connecting member 2 comprises a connecting seat 21 disposed on the lower end surface of the housing 1 and an adsorption member 22 disposed on the other side of the connecting seat 21 for connecting with the surface of the cabinet; The mechanical arm 3 includes an inverted L-shaped connecting arm 31 for pressing a button on the surface of the cabinet. One end of the inverted L-shaped connecting arm 31 is transmission-connected to an electric control execution unit inside the shell 1, and the other end of the inverted L-shaped connecting arm 31 is vertically downwardly arranged. The electric control execution unit can move the inverted L-shaped connecting arm 31 up and down to control the closing and opening of the button 4.

[0027] The connecting piece 5 can magnetically attract the shell 1 near the button on the surface of the distribution cabinet, so that the inverted L-shaped connecting arm 3 is located directly in front of the button 4. The operator can stay away from the distribution cabinet and remotely control the electronic control execution unit to operate the motor inside the shell, thereby driving the gear to rotate, so that the rack moves up or down, and then drives the movable seat and the inverted L-shaped connecting arm to move up or down. The inverted L-shaped connecting arm moves toward the button to press the button, thereby replacing manual button pressing operations. Since the operating and maintenance personnel do not need to be too close to the distribution equipment, the danger is reduced, the safety of the system is improved, and it can be installed very conveniently and can be directly adsorbed on the surface of the cabinet, which is convenient to connect.

[0028] Further, as an implementation method, refer to Figure 1 The end of the inverted L-shaped connecting arm 31 located outside the housing 1 is vertically downwardly provided with a pressing rod 32, and the lower end of the pressing rod 32 is provided with a pressing head 33. The inverted L-shaped connecting arm 31, the pressing rod 32, and the pressing head 33 are all made of insulating materials. An end surface of the pressing head 33 away from the pressing rod 32 is provided with an anti-slip rubber pad.

[0029] Further, as a specific implementation method, refer to Figure 1 and Figure 3 , one end of the inverted L-shaped connecting arm 31 located inside the housing 1 is connected to a movable seat 34, a guide rail is provided inside the housing 1 along its up-down direction, a slider matching the guide rail is provided on the movable seat 34, and a first rectangular opening for the inverted L-shaped connecting arm 31 to pass through without hindering the up-down movement is provided on the side of the housing 1 along its up-down direction; the electric control execution unit includes a gear rack transmission pair, and the gear rack transmission pair includes a rack 51 vertically provided on the other side of the movable seat 34 and a gear 52 for transmission connection with the motor. The electric control execution unit makes the motor inside the housing 1 work and then drives the gear 52 to rotate, so that the rack 51 moves upward or downward, and then drives the movable seat 34 and the inverted L-shaped connecting arm 3 to move upward or downward.

[0030] Further, as an implementation method, refer to Figure 1 , and also includes a shell 6, the lower end surface of which is open, and a partition 7 is vertically arranged inside the shell 6 along the front-to-back direction thereof, a first groove chamber for accommodating the inverted L-shaped connecting arm 31 and the button 4 is formed between one side of the partition 7 and the inner wall of the shell 6, and a second groove chamber for accommodating the shell 1 and the connecting member 2 is formed between the other side of the partition 7 and the inner wall of the shell 6, and a second rectangular opening 8 is arranged on the partition 7 along the up-down direction thereof for allowing the inverted L-shaped connecting arm 31 to pass through without hindering the up-and-down movement; a card plate 10 is also arranged at the lower end of the shell 6 for closing the second groove chamber.

[0031] Furthermore, as a specific implementation, a control unit and a wireless communication module are also disposed inside the housing 1 .

[0032] The control unit is the core of the entire device, which adopts an embedded system architecture, including a microcontroller, a signal processing circuit and a power management module. The microcontroller uses a high-performance, low-power chip that can quickly respond to and process various control instructions. The signal processing circuit filters, amplifies and demodulates the received wireless signal to ensure the accuracy and stability of the signal. The power management module is responsible for providing a stable power supply for each component to extend the service life of the device.

[0033] The wireless communication module is the key to realize remote control. It adopts Bluetooth 5.0 technology, has the characteristics of low power consumption, high reliability, strong anti-interference ability, etc., and is suitable for wireless communication in complex environments. The device needs to download a dedicated APP to control it. The device receives the opening and closing signals through the Bluetooth receiving module and then controls the motor to drive the rack and pinion transmission pair to move the mechanical arm up and down to control the opening and closing of the button. The magnet is used to adsorb to the surface of the cabinet to fix the device on the surface. The connection seat is an iron pad that cooperates with the magnet to provide fixing force, and the adsorption effect is very good. The shell adopts 3D printing technology and is made of white resin.

[0034] Example 2 According to the working principle of the present application, before use, the shell 1 is first magnetically attracted to the surface of the switch cabinet near the button 4 through the connector 2, so that the inverted L-shaped connecting arm 31 is located directly in front of the button 4, and then the operator moves away from the switch cabinet and remotely controls the electric control execution unit to operate the motor inside the shell 1, thereby driving the gear 52 to rotate, so that the rack 51 moves up or down, and then drives the movable seat 34 and the inverted L-shaped connecting arm 31 to move up or down. The inverted L-shaped connecting arm 31 moves in the direction close to the button to press the button, thereby replacing the manual button pressing operation. However, when the buttons 4 are densely packed, that is, the shell 1 cannot be magnetically attracted to the cabinet surface due to insufficient spacing between the buttons, in order to facilitate the magnetic attraction of the shell 1 in the dense button 4 area.

[0035] The present invention provides a wireless electromagnetic suction on-off system, referring to Figure 2 , Figure 3 and Figure 5, a screw 23 is vertically upwardly arranged on one side of the connection seat 21 close to the shell 1, and a first internal threaded channel penetrating the lower end surface thereof and matching the screw 23 is vertically downwardly arranged inside the shell 1; the adsorbent 22 is one or any combination of a magnet, a suction cup, and a paste; there are a plurality of connection members 2, and a plurality of connection members 2 are sequentially arranged along the edge of the lower end surface of the shell 1. When the buttons 4 are densely packed, the connection seat 21 can be moved away from the shell 1 by sequentially screwing a plurality of screws 23, and while ensuring that the adsorbent 22 is connected to the surface of the cabinet, the buttons 4 that hinder magnetic attraction are located at the bottom of the shell 1, so that the shell 1 can be used in a densely packed button area.

[0036] Further, as a specific implementation, a second screw 35 is provided at one end of the pressing rod 32 away from the pressing head 33, and the length direction of the second screw 35 is arranged along the length direction of the pressing rod 32, and a second internal threaded channel adapted to the second screw 35 is arranged inside the vertical section of the inverted L-shaped connecting arm 31. As the distance between the housing 1 and the cabinet surface becomes farther, the distance between the inverted L-shaped connecting arm 31 and the cabinet surface also becomes farther. In order not to hinder the pressing operation of the pressing head 33 on the button, the distance between the pressing head 33 and the button needs to be adjusted, and the distance between the pressing head 33 and the button can be adjusted by screwing the second screw 35.

[0037] Example 3 According to the working principle of the present application, before use, the housing 1 is first magnetically attracted to the surface of the distribution cabinet near the button 4 through the connecting piece 2, so that the inverted L-shaped connecting arm 31 is located directly in front of the button 4, and then the operator moves away from the distribution cabinet and remotely controls the electric control execution unit to operate the motor inside the housing 1, thereby driving the gear 52 to rotate, so that the rack 51 moves upward or downward, and then drives the movable seat 34 and the inverted L-shaped connecting arm 31 to move upward or downward. The inverted L-shaped connecting arm 31 moves in the direction close to the button to press the button, thereby replacing the manual button pressing operation, and the existing button pressing operation is not performed by the operator. There are differences in the specifications and strokes of buttons. When the inverted L-shaped connecting arm 31 moves downward through the motor to press the button, it is necessary to stop pressing when the button stroke is reached. However, the inverted L-shaped connecting arm 31 does not have a detection function and has a tendency to continue moving downward with the motor. When the maximum stroke of the button is reached, if the inverted L-shaped connecting arm 31 wants to continue moving downward, two possible consequences will occur. First, the button will be damaged by pressing; second, the connecting piece 2 will be separated from the cabinet surface, and the shell 1 will fall to the ground and be broken. Therefore, it is necessary to stop the inverted L-shaped connecting arm 31 from moving downward after the button reaches the maximum stroke.

[0038] The present invention provides a wireless electromagnetic suction on-off system, referring to Figure 1 , Figure 5 and Figure 6, on the basis of Example 1, it also includes an overpressure protection component, which is arranged inside the inverted L-shaped connecting arm 31, the inverted L-shaped connecting arm 31 includes a first connecting arm 311 arranged horizontally and a second connecting arm 312 arranged vertically, one end of the first connecting arm 311 is connected to the movable seat 34, the overpressure protection component includes a limiting opening 91 arranged at the other end of the first connecting arm 311 for the upper end of the second connecting arm 312 to pass through, the second internal threaded channel 36 is located inside the lower end of the second connecting arm 312, the first connecting arm 311 is provided with a first sliding cavity 92 along its length direction, the first A first guide hole 95 communicating with the limiting opening 91 is provided at one end of the sliding cavity 92, a pressure relief assembly 93 is provided inside the first sliding cavity 92, and the pressure relief assembly 93 includes a limiting seat 931, one end face of the limiting seat 931 is provided with a first guide block adapted to the first guide hole 95, a limiting head 932 is provided at the other end of the first guide block, a limiting groove 934 adapted to the limiting head 932 is provided on the upper end side face of the second connecting arm 312, a connecting head 933 is provided on the other end face of the limiting seat 931, and a return spring 935 is provided between the connecting head 933 and the first sliding cavity 92. The thrust of the reset spring 935 can make the limit head 932 have a certain force to limit the displacement inside the limit groove 934. When the pressure at the second connecting arm 312 exceeds the limit force of the limit head 932, the limit groove 934 will squeeze the limit head 932 so that the limit head 932 retracts into the first guide hole 95. The second connecting arm 312 can slide in the limit opening 91 to protect the button and the device.

[0039] The lower side surface of the limiting head 932 is rounded at one end away from the first guide block; the lower inner wall of the limiting groove 934 is also rounded.

[0040] Example 4 According to the working principle of the overpressure protection component in the present application, when the button 4 reaches the maximum stroke, as the first connecting arm 311 continues to move downward, the limiting groove 934 will squeeze the limiting groove 934, and then the limiting groove 934 will move in the direction of the first sliding cavity, thereby releasing the restriction of the second connecting arm 312 on the first connecting arm 311, allowing the first connecting arm 311 to slide in the limiting opening 91, thereby preventing the first connecting arm 311 from continuing to move downward, which can well protect the button and the device. However, the pressing force required for each button 4 is different. When the button 4 requires a larger pressing force and the pressing force is greater than the limiting force of the overpressure protection component, the overpressure protection component will start working before the button is successfully pressed, which is not what we need to see.

[0041] The present invention provides a wireless electromagnetic suction on-off system, referring to Figure 3 , Figure 4 , Figure 5 and Figure 6 On the basis of Example 3, it also includes a limiting force fine-tuning component 94, the limiting force fine-tuning component 94 includes a second sliding cavity 941 arranged inside the first connecting arm 311 and arranged along the length direction thereof, one end of the second sliding cavity 941 is provided with a second guide hole 96 connected to the first sliding cavity 92, the length direction of the second guide hole is arranged along the length direction of the first sliding cavity 92 and the second sliding cavity 941, a screw rod 942 is arranged inside the second sliding cavity 941 along the length direction thereof, a ball nut slider 943 is adapted on the screw rod 942, and a ball nut slider 943 is arranged on one end surface thereof The second guide hole 96 is adapted to a guide rod 944, and the other end of the guide rod 944 extends to the inside of the first slide cavity 92 through the second guide hole 96 and is connected to a push plate 945. The return spring 935 is located between the push plate 945 and the connector 933. A worm gear 946 is coaxially arranged at one end of the lead screw 942 away from the first slide cavity 92. A worm 946 is meshed on the worm gear 946. The upper and lower ends of the worm 946 are respectively connected to the inner wall of the second slide cavity 941 through bearings, and the upper end of the worm 946 passes through the inner wall of the second slide cavity 941 and is coaxially connected to a knob 948. By turning the knob 948, the worm can be rotated, thereby driving the rotation of the worm wheel, causing the screw 942 to rotate, and then the ball nut slider 943 to move left or right inside the second sliding cavity, thereby driving the push plate 945 to move left or right inside the first sliding cavity, thereby adjusting the elastic force of the return spring, and then realizing corresponding fine-tuning of the limiting force of the limit head according to the different pressing forces required for the corresponding buttons.

[0042] The upper side surface of the first connecting arm 311 is provided with an annular groove 949 for accommodating the knob 948 .

[0043] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
