[0002] Automated commissioning devices for distribution terminals can be used to commission, test, and maintain distribution terminal equipment, improving the quality and efficiency of commissioning work and ensuring the stable operation of the distribution network. However, in actual commissioning processes, rainy and humid weather is frequently encountered, causing a large amount of moisture to enter the equipment. This moisture condensation can lead to corrosion of internal parts, resulting in equipment failure. Summary of the Invention
[0003] To address the shortcomings of existing technologies, this invention aims to provide an automated testing device for power distribution terminals. This device can effectively ventilate and dissipate heat inside the equipment and effectively remove moisture from inside the equipment, thereby effectively ensuring the stability of equipment operation.
[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An automated testing device for a power distribution terminal includes an automated tester and a housing. A cover is installed at the top opening of the housing, and the automated tester is mounted on a panel at the opening. Below the panel, the housing has an interior cavity with an exhaust port on one side and an air inlet on the other. A dust filter is installed at the air inlet. A controllable closure assembly is installed at the exhaust port. A heat dissipation assembly is installed inside the cavity near the exhaust port. A dehumidifier is installed on the side of the cavity away from the air inlet, and its drain pipe extends into a maintenance groove on the outer wall of the housing and communicates with a collection bottle. An openable and closable door stop is installed at the opening of the maintenance groove. A clamping assembly is installed at the bottom of the maintenance groove to secure the collection bottle.
[0005] Preferably, the controllable closing assembly includes a linkage assembly and multiple closing strips, wherein the closing strips are arranged horizontally and vertically at equal intervals at the exhaust port; the two sides of the closing strips are rotatably connected to the two sides of the exhaust port; the actuating part of the linkage assembly is connected to the inner side of the closing strips for driving them to flip and close.
[0006] Preferably, the linkage assembly includes a first link, a second link, a third link, and a telescopic cylinder. One end of the inner side of the sealing strip is rotatably connected to the vertically arranged first link. The middle part of the first link is rotatably connected to one end of the second link. The other end of the second link is rotatably connected downwardly to one end of the third link. The middle part of the third link is rotatably connected to the inner wall of the cavity. The other end of the third link is rotatably connected to the piston rod of the telescopic cylinder. The tail of the telescopic cylinder is rotatably connected to the bottom of the cavity.
[0007] Preferably, the upper outer edge and lower inner edge of the closed strip are provided with mating grooves.
[0008] Preferably, the dust filtration assembly includes a dust filter screen that is detachably installed at the air inlet.
[0009] Preferably, the clamping assembly includes two clamping arms and a clamping plate. The bottom of the maintenance groove is provided with an installation cavity. The two clamping arms are horizontally and symmetrically installed in the cavity. The clamping arms are bent rods with obtuse angles facing each other. The middle bent part of the clamping arm is rotatably connected to the cavity. The bottom of the maintenance groove extends downward through the cavity and has a first vertical hole and a second vertical hole. The clamping plate is movably disposed in the first vertical hole and its lower end is installed on one end of the clamping arm. The other ends of the two clamping arms respectively abut against the first inclined surfaces on both sides of the wedge block. The wedge block is slidably installed in the cavity along the length direction of the clamping arm. A pressure block is vertically and movably installed in the second vertical hole. The upper end of the pressure block extends out of the second vertical hole and is placed in the maintenance groove. The lower end of the pressure block extends into the cavity and abuts against the wedge block. The lower end of the pressure block and the upper end of the wedge block are provided with mutually cooperating second inclined surfaces.
[0010] Preferably, a spring is horizontally provided at the tail of the wedge block, and the spring abuts against the inner wall of the cavity.
[0011] Preferably, a limiting block is fixed in the middle of the chamber for the pressure block.
[0012] Preferably, the clamp is an arc-shaped plate that fits with the outer wall of the collection bottle, and the arc-shaped plate is hinged to the clamp arm.
[0013] Preferably, one side of the lid is hinged to the side of the box body, and the lid is fixedly connected to the box body by a snap-fit structure.
[0014] The beneficial effects of this invention are as follows: 1. This device monitors temperature and humidity in real time. When the temperature and humidity in the cavity are too high, the linkage component can control the sealing strip at the exhaust port, thereby effectively regulating the opening and closing degree of the exhaust port. Through the operation of the heat dissipation component and dehumidifier, effective heat dissipation and dehumidification can be achieved.
[0015] 2. This application utilizes the telescopic cylinder's telescopic movement to allow the third connecting rod to rotate around the central hinge point. This, in turn, drives the vertically positioned first connecting rod to move up and down via the second connecting rod, thereby causing the sealing strips to swing around the pivot point. This adjusts the opening and closing distance between the sealing strips. Furthermore, based on the temperature and humidity detector's readings, and in conjunction with the ventilation operation of the heat dissipation component, the opening and closing degree of the exhaust port can be effectively adjusted. This not only effectively regulates the heat dissipation effect within the cavity but also effectively controls the degree of exhaust port opening, preventing foreign objects from entering the cavity.
[0016] 3. The collection bottle of this device can effectively collect water collected during dehumidification operations, preventing water stains from being directly discharged outside the casing and causing pollution to the working environment. The clamping assembly can effectively clamp and fix the collection bottle, and provides great convenience during the installation and removal of the collection bottle, making wastewater cleaning and installation of the collection bottle more convenient and efficient.
[0017] 4. Under the action of spring force, this application can push the wedge block towards the collection bottle, and use the first inclined surface to squeeze the two clamping arms, so that the two clamping plates at the other end of the clamping arms can come closer to each other, thereby effectively clamping and fixing the collection bottle placed at the bottom of the maintenance tank. When it is necessary to remove the collection bottle, open the door stop, press down the pressure block, so that the pressure block squeezes the wedge block horizontally away from the collection bottle through the second inclined surface, thereby reducing the clamping force of the clamping arms, and the collection bottle can be easily removed; when the collection bottle is placed again, simply place it between the two clamping plates, release the pressure block, and the clamping plates, clamping arms, and pressure block will be reset by the spring force, realizing the quick reset and clamping fixation of the collection bottle, which is very convenient to use.

Detailed Implementation
[0019] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of the invention.
[0020] like Figure 1-6 As shown, the present invention proposes an automated testing device for a power distribution terminal, including an automated tester 3 and a housing 1. A cover 11 is installed at the opening on the top of the housing 1. The rear side of the cover 11 is hinged to the opening side of the housing 1. The front side of the cover 11 is fixed to the housing 1 by a snap-fit structure, which makes it easier to open and close the cover 11.
[0021] The automated testing instrument 3 is mounted on the panel 2 at the opening of the housing 1. Below the panel 2, the housing 1 contains a cavity with an exhaust port 12 on one side and an air inlet 14 on the other. A dust filter assembly 15, which can be a filter screen, is installed at the air inlet 14. This effectively filters the air entering the housing, preventing impurities and dust from entering the cavity and affecting the stability of the equipment. A heat dissipation assembly 4 is installed inside the cavity near the exhaust port 12. This assembly can be a commonly used exhaust fan structure, which improves airflow within the cavity and enhances heat dissipation efficiency.
[0022] A controllable closing assembly is installed at the exhaust port 12. The controllable closing assembly includes a linkage assembly and multiple sealing strips 121. The sealing strips 121 are arranged horizontally and vertically at equal intervals at the exhaust port 12. The two sides of the sealing strips 121 are rotatably connected to the two sides of the exhaust port 12 via a rotating shaft. The actuating part of the linkage assembly is connected to the inner side of the sealing strips 121 to drive them to flip and close. A temperature and humidity detector 13 is installed inside the cavity, which can detect changes in temperature and humidity inside the cavity in real time. Specifically, the linkage assembly includes a first connecting rod 122, a second connecting rod 123, a third connecting rod 124, and a telescopic cylinder 125. One end of the inner side of the sealing strip 121 is rotatably connected to the vertically arranged first connecting rod 122. The middle of the first connecting rod 122 is rotatably connected to one end of the second connecting rod 123. The other end of the second connecting rod 123 is tilted downwards and rotatably connected to one end of the third connecting rod 124. The middle of the third connecting rod 124 is rotatably connected to the inner wall of the cavity. The other end of the third connecting rod 124 is tilted upwards and rotatably connected to the piston rod of the telescopic cylinder 125. The tail of the telescopic cylinder 125 is rotatably connected to the bottom of the cavity. In this embodiment, the telescopic cylinder 125 adopts a cylinder structure from the prior art.
[0023] This application utilizes the telescopic cylinder 125 to extend and retract, enabling the third connecting rod 124 to rotate around the central hinge point. This, in turn, drives the vertically positioned first connecting rod 122 to move up and down via the second connecting rod 123. Consequently, the sealing strip 121 swings around the pivot point, adjusting the opening and closing distance between the sealing strips 121. Based on the temperature and humidity detector 13, and in conjunction with the blower operation of the heat dissipation assembly 4, the opening and closing degree of the exhaust port 12 can be effectively adjusted. This not only effectively regulates the heat dissipation effect within the cavity but also effectively controls the opening degree of the exhaust port 12, preventing foreign objects from entering the cavity.
[0024] In addition, the upper outer edge and lower inner edge of the sealing strip 121 are provided with mating grooves 1210. The mating grooves 1210 of the uppermost and lowermost sealing strip 121 respectively match the upper and lower edges of the exhaust port 12, thereby effectively improving the sealing performance between the sealing strips 121.
[0025] This device uses the temperature and humidity detector 13 to monitor in real time. When the temperature and humidity in the cavity are too high, the linkage component can control the sealing strip 121 at the exhaust port 12, thereby effectively regulating the opening and closing degree of the exhaust port 12. Through the operation of the heat dissipation component 4 and the dehumidifier 5, effective heat dissipation and dehumidification can be achieved. The dust filter component 15 includes a dust filter screen that is detachably installed at the air inlet 14.
[0026] A dehumidifier 5 is installed on the side of the cavity away from the vent. The drain pipe of the dehumidifier 5 extends into the maintenance groove 16 opened inward on the outer wall of the box 1 and is connected to the collection bottle 6. An openable and closable door stop is installed at the opening of the maintenance groove 16. A clamping assembly is installed at the bottom of the maintenance groove 16 to fix the collection bottle 6. The clamping assembly includes two clamping arms 72 and a clamping plate 71. The bottom of the maintenance groove 16 is provided with an installation cavity. The two clamping arms 72 are horizontally and symmetrically installed in the chamber 17. The clamping arms 72 are bent rods with obtuse angles facing each other. The middle bent part of the clamping arms 72 is rotatably connected in the chamber 17. The bottom of the maintenance groove 16 extends downward through the chamber 17 and has a first vertical hole and a second vertical hole 172. The clamping plate 71 is movably disposed in the first vertical hole and its lower end is installed on one end of the clamping arm 72. The clamping plate 71 is an arc-shaped plate that cooperates with the outer wall of the collection bottle 6. The arc-shaped plate is hinged to the clamping arm 72, so that it can effectively abut against the outer wall of the collection bottle 6 and improve the clamping stability. The other ends of the two clamping arms 72 respectively abut against the first inclined surfaces 731 on both sides of the wedge block 73. The wedge block 73 is slidably installed in the chamber 17 along the length of the clamping arms 72 through the slide 171 at the bottom of the chamber 17. A pressure block 74 is vertically and movably installed in the second vertical hole 172. The upper end of the pressure block 74 extends out of the second vertical hole 172 and is placed in the maintenance groove 16. The lower end of the pressure block 74 extends into the chamber 17 and abuts against the wedge block 73. The lower end of the pressure block 74 and the upper end of the wedge block 73 are provided with mutually cooperating second inclined surfaces 732. A spring 75 is horizontally provided at the tail of the wedge block 73, and the spring 75 abuts against the inner wall of the chamber 17. A limiting block 741 is fixedly provided in the middle of the chamber 17 for the pressure block 74.
[0027] Under the elastic force of spring 75, this application can push the wedge block 73 to move towards the collection bottle 6, and use the first inclined surface 731 to squeeze the two clamping arms 72, so that the two clamping plates 71 at the other end of the clamping arms 72 can move closer to each other, thereby effectively clamping and fixing the collection bottle 6 placed at the bottom of the maintenance groove 16. When it is necessary to remove the collection bottle 6, open the door stop and press down the pressure block 74, so that the pressure block 74 squeezes the wedge block 73 horizontally away from the collection bottle 6 through the second inclined surface 732, thereby reducing the clamping force of the clamping arms 72, and the collection bottle 6 can be easily removed. When the collection bottle 6 is put back, simply place it between the two clamping plates 71, release the pressure block 74, and use the elastic force of spring 75 to reset the clamping plates 71, clamping arms 72, pressure block 74, etc., to achieve quick reset and clamping fixation of the collection bottle 6, which is very convenient to use.
[0028] The collection bottle 6 of this device can effectively collect the water collected during the operation of the dehumidifier 5, preventing water stains from being directly discharged outside the housing 1 and causing pollution to the working environment. The clamping assembly can effectively clamp and fix the collection bottle 6. By pressing down on the pressure block 74, the wedge block 73 is moved backward and away from the collection bottle 6, reducing the contact force with the two clamping arms 72. This allows the collection bottle 6 to be easily removed from between the two clamping plates 71, providing great convenience during the installation and removal of the collection bottle 6, and making the wastewater cleaning and installation of the collection bottle 6 more convenient and efficient.
