With the acceleration of electrification, the stability and safety of power distribution systems face higher requirements. Traditional manual inspection of distribution boxes during production and use is inefficient and risky, creating an urgent market need for intelligent, high-precision testing equipment to achieve rapid diagnosis and preventative maintenance. Utility Model Content

[0003] The purpose of this invention is to provide an intelligent detection device for distribution box wiring to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an intelligent detection device for distribution box wiring, including a base for supporting the distribution box, and an electrical control box for detection is provided on the side of the base; The top of the electrical control box is equipped with a multi-color indicator light for detecting poor wiring. The top of the electrical control box is also equipped with a reset switch and a two-position switch for control. The interior of the electrical control box is equipped with an intermediate relay for detection, a single-coil solenoid valve, a color mark detector, a proximity switch, and a time relay. The side of the electrical control box is connected to an audible and visual alarm light for alerting the user. The side of the electrical control box is also connected to a three-phase four-wire power supply for signal transmission.

[0005] Preferably, a first cylinder is installed at the bottom of the base, a connecting frame is connected to the movable part of the first cylinder, and a movable block is installed at the end of the connecting frame.

[0006] Preferably, the top of the base is equipped with a support platform for supporting the distribution box, and the surface of the support platform is provided with a guide groove for moving the moving block.

[0017] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0018] like Figures 1 to 5 The intelligent detection distribution box wiring device shown includes a base 2 for supporting the distribution box, and an electrical control box 1 for detection is provided on the side of the base 2. The top of the electrical control box 1 is equipped with a multi-color indicator light 101 for detecting poor wiring. The top of the electrical control box 1 also houses a reset switch 103 and a two-position switch 104 for control. Inside the electrical control box 1 are installed intermediate relays 105, a single-coil solenoid valve 106, a color mark detector 107, a proximity switch 108, and a time relay 109 for detection. The intermediate relay 105 is a voltage relay, primarily used for signal amplification, conversion, and multiplexing in the circuit. It has a large number of contacts with relatively large contact capacity, enabling it to establish a connection between low-voltage, low-current control signals and high-voltage, high-current controlled circuits. When a control signal is input to the coil of the intermediate relay 105, the coil generates a magnetic field, attracting the armature and causing the contacts to close or open, thereby controlling the operation of other electrical components. In intelligent detection distribution box wiring equipment, it can be used to amplify weak control signals from the control module to drive higher-power equipment, or to achieve signal branching control, simultaneously controlling multiple loads. The single-coil solenoid valve 106 consists of a solenoid coil and a valve body. The valve is opened and closed by the magnetic force generated by energizing the solenoid coil. When the solenoid coil is energized, the generated magnetic force attracts the valve core, causing the valve to open or close, thereby realizing the on / off control of fluids (such as gas and liquid). When the coil is de-energized, the valve core returns to its original position by the elastic force of the spring or its own gravity, and the valve returns to its initial state. In the context of distribution boxes, the single-coil solenoid valve 106 can be used to control the flow of fluid in the cooling system to achieve heat dissipation control of the distribution box; or it can be used to control the air path to achieve the action control of certain pneumatic components. The color mark detection 107 is a device that uses photoelectric principle to detect the color and color mark of an object. It is used to detect whether the markings and labels on the outer shell of the distribution box meet the requirements. The proximity switch 108 is a sensor that can detect the position without direct mechanical contact with moving parts. It uses principles such as electromagnetic induction, capacitance change, and Hall effect. When an object approaches the sensing surface of the switch to a certain distance, the switch can send a signal to detect the presence of the object. It is used to detect whether certain movable parts are in the correct position to ensure the safe operation of the equipment. A time relay 109 is a control device that uses electromagnetic or mechanical principles to achieve delayed connection or disconnection of contacts. After receiving an input signal, its contacts will only activate after a set time delay. Time relays 109 come in two types: power-on delay and power-off delay, which can be selected according to different control requirements. In a distribution box circuit, the time relay 109 can be used to control the starting sequence of equipment, achieving delayed start-up and avoiding current surges caused by multiple devices starting simultaneously; it can also be used to control the running time of equipment, automatically stopping the equipment after a set time, thus playing a timing control role. The side of the electrical control box 1 is connected to an audible and visual alarm light 102 for alerting users. If there is a short circuit, leakage, disconnection, or incorrect wiring in the distribution box, an alarm sound will be triggered, and the corresponding audible and visual alarm light 102 will flash for the phase wire (yellow-green-red) + neutral wire (blue), allowing for quick identification and rectification of wiring defects. For large distribution boxes and distribution boxes in use, the plug-in connector power cord can be lengthened, and the connector can be used as a mobile device without being fixed. The size of the plug-in connector can be reduced, and it can be manually placed into the large distribution box to test electrical wiring, etc. The side of the electrical control box 1 is connected to a three-phase four-wire power cord 305 for transmitting signals.

[0019] A first cylinder 205 is installed at the bottom of the base 2. A connecting frame 206 is connected to the movable part of the first cylinder 205. A moving block 203 is installed at the end of the connecting frame 206. A support platform 201 for supporting the distribution box is installed at the top of the base 2. A guide groove 202 for moving the moving block 203 is provided on the surface of the support platform 201. A U-shaped clamp 204 for fixing the distribution box is installed on the outer periphery of the moving block 203. Two positioning plates 304 for limiting the position of the distribution box are installed at the top of the base 2. When the distribution box to be tested is placed on the support platform 201, the movable part of the first cylinder 205 is shortened. The connecting frame 206 drives the moving block 203 and the U-shaped clamp 204 to move. The U-shaped clamp 204 drives the distribution box to move downwards towards the limiting plate 302. Finally, the distribution box moves to the designated position. The distribution box is connected to the three-phase four-wire power supply line 305 led out from the electrical control box 1.

[0020] A support bracket 3 is welded to the top of the base 2. A second cylinder 301 is installed on the top of the support bracket 3. The movable part of the second cylinder 301 is connected to a limit plate 302. Multiple probes 303 for detecting the position of the distribution box are installed at the bottom of the limit plate 302. A foot switch 4 for control is connected to the side of the electrical control box 1. The probes 303 are fixed to the limit plate 302 with plug-in connectors according to the usage scenario. The fixture consists of an X-axis and a Y-axis. A first cylinder 205 and a second cylinder 301 are installed in the two directions respectively. An induction switch is installed on the fixture. After the program is set, simply open the distribution box door and place it on the fixture. The plug-in connector with the probes 303 will be connected to the designated component or circuit. The test is started by turning on the connected foot switch 4. The test is completed after 1 to 3 seconds.

[0021] Working principle When using this intelligent distribution box wiring detection device, the distribution box to be tested is first placed on the support platform 201. The movable part of the first cylinder 205 shortens, and the connecting frame 206 drives the moving block 203 and the U-shaped clamp 204 to move. The U-shaped clamp 204 moves the distribution box downwards towards the limit plate 302. Finally, the distribution box moves to the designated position, and the three-phase four-wire power line 305 leads out from the electrical control box 1 for connection. The probe 303 is fixed to the limit plate 302 with a plug-in connector according to the usage scenario. The clamp consists of X-axis and Y-axis components, installed in two directions respectively. The device has a first cylinder 205 and a second cylinder 301. An inductive switch is installed on the fixture. After the program is set, simply open the distribution box door and place it on the fixture. The plug-in connector with probe 303 will connect to the designated component or circuit. Testing begins by activating the connected foot switch 4. The test is completed after 1 to 3 seconds. If the distribution box has short circuits, leakage, disconnections, or incorrect wiring, an alarm will sound. Simultaneously, the corresponding audible and visual alarm light 102 for the phase wire (yellow-green-red) and neutral wire (blue) will flash, allowing for quick identification and rectification of wiring defects. For larger or in-use distribution boxes, the plug-in connector power cord can be extended, allowing for mobile use without a fixed connector. The smaller size of the plug-in connector allows for manual placement inside large distribution boxes to test electrical wiring.
