[0001] The present invention relates to the technical field of power distribution cabinet monitoring, and specifically to an internal environment monitoring device for a power distribution cabinet. Background Technique

[0002] In order to ensure the normal operation of the power distribution cabinet, it is necessary to regularly maintain the power distribution cabinet, including regularly detecting whether the electrical components are leaking electricity. After retrieval, the Chinese invention patent with the application number CN202411057118.8 discloses a safety performance detection device for a power distribution cabinet, which conducts contact detection through an electrical detection contact probe and a wiring terminal, and actively monitors the wiring terminal in the electrical equipment and performs corrective operations when necessary under the condition of no human intervention, greatly improving the reliability and safety of the electrical system.

[0003] The above device needs to adjust the electrical detection contact probe to align with the wiring terminal. Since the installation positions and sizes of the wiring terminals inside the power distribution cabinet are uncertain, it is necessary to pre-adjust the detection position of the electrical detection contact probe according to the specific installation situation of each wiring terminal inside the power distribution cabinet before use. When it is necessary to monitor a large number of power distribution cabinets internally, the monitoring device is difficult to adapt to wiring terminals with different positions and sizes, and the commissioning work before use takes a lot of time.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1

[0033] In order to enable the monitoring device of the power distribution cabinet to adapt to terminal blocks 2 of different sizes and can be directly used without debugging, please refer to Figures 1-4 , this embodiment proposes an internal environment monitoring device for a power distribution cabinet, including a base 3 and a terminal block 2 installed in a cabinet body 1. A drive component 9 is installed on the top of the base 3, and a bracket 4 is installed on the top of the drive component 9. The drive component 9 drives the bracket 4 to move along directions parallel and perpendicular to the base 3. A monitoring component 5 is installed on the top of the bracket 4. The monitoring component 5 includes a slider 52, an elastic arc plate 54 and a transverse monitoring probe 55. The slider 52 is slidably connected to the bracket 4. An elastic plate 53 is installed between the two sliders 52. The elastic arc plate 54 is installed on the side of the slider 52 away from the bracket 4. The transverse monitoring probe 55 is installed at one end of the elastic arc plate 54 close to the terminal block 2.

[0034] During use, the drive component 9 drives the bracket 4 to move along the length direction of the base 3 until it moves to a position directly opposite the terminal block 2 to be monitored. Then, the drive component 9 drives the bracket 4 to move along the width direction of the base 3, so that the monitoring component 5 on the bracket 4 gradually approaches the terminal block 2. At this time, there are two situations:

[0035] First, when the volume of the terminal 2 is small and the monitoring component 5 is directly opposite the terminal of the terminal 2, the lateral monitoring probe 55 gradually approaches the terminal 2 along with the bracket 4 until the lateral monitoring probe 55 contacts the terminal of the terminal 2 and receives the information of the terminal 2.

[0036] Second, when the volume of the terminal 2 is large, the monitoring component 5 is located in the middle of the upper and lower terminals of the terminal 2. After the lateral monitoring probe 55 and the elastic arc plate 54 contact the terminal 2, the lateral monitoring probe 55 and the elastic arc plate 54 are blocked by the terminal 2. After the elastic arc plate 54 bends, it extends towards the upper and lower ends of the terminal 2, driving the lateral monitoring probe 55 to move simultaneously until the elastic arc plate 54 extends to the terminals at the upper and lower ends of the terminal 2. At this time, the lateral monitoring probe 55 contacts the terminal of the terminal 2 and receives the information of the terminal 2.

[0037] When it is necessary to monitor the next terminal 2, only the driving component 9 needs to drive the bracket 4 to move along the width direction of the base 3 to the starting point, and then the driving component 9 drives the bracket 4 to move to the next terminal 2 to be monitored. Repeat the above process to monitor the terminals 2 one by one. After completion, the driving component 9 drives the bracket 4 and the monitoring component 5 to move to the starting point. During use, the width of the monitoring component 5 can be adjusted to adapt to terminals 2 of different sizes, without the need to pre-adjust the detection position, can adapt to terminals at different positions and sizes, and reduces the time occupied by the commissioning work before use.

[0038] Embodiment 2

[0039] Since the angle of the elastic arc plate 54 will change after being bent by squeezing the terminal 2, in order to keep the lateral monitoring probe 55 on the elastic arc plate 54 always in the horizontal direction and facilitate monitoring towards the terminal 2 when approaching the terminal 2, referring to Figures 1-5 , on the basis of Embodiment 1, the lateral monitoring probe 55 includes a universal ball 552, a cross bar 553, a contact probe 554 and a counterweight ball 555. The universal ball 552 movably penetrates the elastic arc plate 54, the cross bar 553 penetrates the universal ball 552, the contact probe 554 is installed at one end of the cross bar 553 close to the terminal 2, and the end of the cross bar 553 far from the terminal 2 movably penetrates the counterweight ball 555. The contact probe 554 includes sensing elements of a voltage sensor, a current sensor, a temperature sensor and a humidity sensor.

[0040] During use, the driving component 9 drives the bracket 4 and the monitoring component 5 to gradually approach the terminal 2. First, the contact probe 554 contacts the terminal 2. After being blocked by the terminal 2, it deflects to one side, driving the cross bar 553 to rotate along the universal ball 552. Then, the elastic arc plate 54 is also bent after being blocked by the terminal 2. At the same time, the elastic arc plate 54 gradually extends towards the upper and lower ends of the terminal 2 until the elastic arc plate 54 moves from the protruding part in the middle of the terminal 2 to the terminals at the upper and lower ends. The thickness of the upper and lower ends of the terminal 2 decreases, and the degree of blocking of the elastic arc plate 54 is reduced, so the elastic arc plate 54 extends towards the terminal 2 for a certain distance.

[0041] At the same time, the contact probe 554 is no longer blocked by the terminal 2. The cross bar 553 returns to the horizontal direction after the gravity of the contact probes 554 and the counterweight balls 555 at both ends is balanced. During the process of the driving component 9 driving the monitoring component 5 to continue moving towards the terminal 2, the contact probe 554 gradually approaches the terminal of the terminal 2. Until the contact probe 554 contacts the terminal and monitors the magnetic flux. After completing the monitoring of the terminal 2, the driving component 9 drives the bracket 4 and the monitoring component 5 back to the starting point, which can maintain the contact probe 554 in the horizontal direction, so that the influence on the contact probe 554 is small when the elastic arc plate 54 is bent to expand the contact width with the terminal 2, ensuring that the contact probe 554 is directly opposite to the terminal 2 when the driving component 9 drives the bracket 4 to approach the terminal 2.

[0042] Embodiment 3

[0043] Since the monitoring results of the power distribution cabinet need to be compared with the preset values, and the preset values are generally based on the standard values of the cables. In order to improve the pertinence of the monitoring results to the cables inside the power distribution cabinet and make the monitoring results more accurate in reflecting the cables inside the power distribution cabinet, referring to Figures 1-6 , on the basis of Embodiment 1, a horizontal groove 6 penetrating the bracket 4 is provided on the side of the bracket 4 away from the terminal 2. A display 7 is fixedly connected to one end of the inner part of the horizontal groove 6 away from the terminal 2. A memory 8 electrically connected to the display 7 is installed inside the horizontal groove 6. The contact probe 554 transmits multiple groups of data of the initially monitored terminal to the memory 8 for internal storage and displays them on the display 7.

[0044] During use, the driving component 9 drives the monitoring component 5 to monitor the wiring terminal 2 when the power distribution cabinet is first used, and transmits the data obtained after the contact probe 554 contacts the wiring terminal 2 to the memory 8. The memory 8 stores the data of the wiring terminal 2 in the initial stage of the use of the power distribution cabinet and displays the data on the display 7. When the monitoring component 5 monitors the wiring terminal 2 subsequently, the monitored data is compared with the data displayed on the display 7, so that the data of the internal environment of the power distribution cabinet in the initial stage of use can be monitored and stored, which is convenient for comparing the data with the initial data when monitoring the internal environment of the power distribution cabinet subsequently, making the monitoring results of the interior of the power distribution cabinet more targeted and improving the accuracy of the monitoring of the internal environment of the power distribution cabinet.

[0045] Embodiment 4

[0046] To improve the waterproof ability of power distribution cabinets of different sizes, referring to Figures 1-8 , on the basis of Embodiment 1, the base 3 includes a support block 31, an arc-shaped rubber block 32 and a waterproof component 33. The support block 31 is fixedly connected to the inner bottom of the cabinet body 1. The arc-shaped rubber block 32 is installed at both ends of the support block 31. A long groove 34 is formed at the top of the support block 31. A water leakage groove 35 communicating with the long groove 34 is formed on one side of the support block 31 away from the wiring terminal 2. The waterproof component 33 is installed inside the long groove 34.

[0047] During use, the support block 31 is installed at the inner bottom of the cabinet body 1. When the length of the power distribution cabinet is greater than the length of the support block 31 but less than the total length of the support block 31 and the two arc-shaped rubber blocks 32, the arc-shaped rubber block 32 bends after being blocked by the inner wall of the power distribution cabinet. The deformed arc-shaped rubber block 32 presses the inner wall of the power distribution cabinet with greater force under its own elastic force. The waterproof component 33 blocks water from entering the power distribution cabinet from the bottom of the base 3, enabling the base 3 to adapt to power distribution cabinets of different sizes and preventing water from entering the power distribution cabinet from the gap between the base 3 and the inner wall of the cabinet body 1.

[0048] To improve the waterproof ability of the power distribution cabinet, reduce the moisture entering the interior of the power distribution cabinet, and accelerate the drying speed of the water entering the interior of the power distribution cabinet, referring to Figure 8 , the waterproof component 33 includes a rubber frame 331 and a partition plate 332. Both ends of the rubber frame 331 are fixedly connected to the support block 31. The bottom of the rubber frame 331 is open and provided with a transverse protrusion 333. The width of the lower half area of the rubber frame 331 gradually decreases. The partition plate 332 is installed inside the rubber frame 331. A plurality of ventilation holes 334 are formed at the top of the rubber frame 331.

[0049] During use, during the process of monitoring the internal wiring terminals 2 of the power distribution cabinet, the driving component 9 drives the bracket 4 and the monitoring component 5 to move. During this process, the driving component 9 squeezes the rubber frame 331 below. When the driving component 9 moves to the ventilation hole 334 on the rubber frame 331, the driving component 9 blocks the ventilation hole 334 and simultaneously squeezes the rubber frame 331 downward to form a depression, so that the air between the two partition plates 332 inside the rubber frame 331 is squeezed out from the bottom of the rubber frame 331. The leaked air sprays onto the water in the water leakage groove 35 and enters the water inside the power distribution cabinet, spraying the water that enters the power distribution cabinet to the outside of the power distribution cabinet. At the same time, the drying speed of the water entering the power distribution cabinet is accelerated by the airflow. The horizontal convex part 333 reduces the possibility of water entering the inside of the rubber frame 331 from the bottom after the rubber frame 331 is squeezed and shaken. When the driving component 9 moves away from the ventilation hole 334, the originally squeezed and bent rubber frame 331 gradually returns to its original state, and the air inside the power distribution cabinet passes through the ventilation hole 334 and then replenishes into the inside of the rubber frame 331. It is possible to guide the directional flow of air by monitoring the internal environment of the power distribution cabinet, so that the airflow sprays towards the bottom of the cabinet door of the power distribution cabinet, which is the position most likely to get water in. On the one hand, the water that enters the power distribution cabinet is blown out of the power distribution cabinet, and on the other hand, the drying speed of the water that enters the power distribution cabinet is accelerated.

[0050] In order to drive the monitoring component 5 to move towards the specified position, referring to Figure 2 and Figure 8 , the driving component 9 includes a horizontal block 91, a roller 92, a horizontal driver 93 and a vertical driver 94. The horizontal block 91 is slidably connected to the top of the base 3. The roller 92 is installed at the bottom of the horizontal block 91. The horizontal driver 93 is installed at the top of the base 3 and drives the horizontal block 91 to move along the length direction of the base 3. The vertical driver 94 is installed at the top of the horizontal block 91 and drives the bracket 4 to move along the width direction of the base 3. The horizontal driver 93 includes a motor one 931 and a threaded rod one 932. One end of the base 3 is provided with a bent frame for fixing the motor one 931. One end of the threaded rod one 932 is fixedly connected to the output end of the motor one 931. The threaded rod one 932 movably penetrates the horizontal block 91. The vertical driver 94 includes a frame 941, a motor two 942 and a threaded rod two 943. The frame 941 is fixedly connected to the top of the horizontal block 91. The threaded rod two 943 is installed between the two sides of the frame 941 and movably penetrates the bracket 4. The motor two 942 is installed on one side of the frame 941 and drives the threaded rod two 943 to rotate.

[0051] During use, the motor one 931 drives the threaded rod one 932 to rotate, thereby driving the horizontal block 91, the bracket 4 and the monitoring component 5 to move along the length direction of the power distribution cabinet. The motor two 942 drives the threaded rod two 943 to rotate, thereby driving the bracket 4 and the monitoring component 5 to move along the width direction of the power distribution cabinet, facilitating the movement of the monitoring component 5 to the specified position as needed.
