Description

Technical Field

[0001] This utility model relates to the field of power distribution equipment technology, and specifically to a detection device for the inside of a power distribution box. Background Technology

[0002] Distribution boxes can distribute electrical energy from the main line to various electrical devices or areas, ensuring that each device or area can obtain the required power supply. Distribution boxes are usually equipped with a variety of detection devices to ensure the stable operation of the power system and the safe distribution of electrical energy. These include the detection of data such as internal temperature, humidity and grounding resistance. Temperature detection is mainly to understand the operating temperature of the electrical components inside the distribution box, and the operating temperature can be used to determine the operating status of the electrical components.

[0003] CN206516933U discloses a device for internal detection of electrical distribution boxes, comprising an anti-static shell, a distribution box body, a temperature sensor, a closed-loop current detection sensor, and a heat sink. The distribution box body has an anti-static shell on its outer side. A temperature sensor is fixedly installed at the top inside the distribution box body. A mounting plate is fixedly installed on the bottom left side inside the distribution box body, and a closed-loop current detection sensor is mounted on the mounting plate. A controller and a heat sink are installed on the bottom right side of the distribution box body. The output terminal of the controller is electrically connected to an audible and visual alarm, a working indicator light, an LCD screen, the temperature sensor, the closed-loop current detection sensor, and the input terminal of the heat sink. This utility model can intuitively display whether the internal circuit of the distribution box is working properly and whether the internal temperature is normal. The heat sink can dissipate heat when the internal temperature of the distribution box exceeds a preset value.

[0004] While the existing technology CN206516933U has many advantages in use, it still has the following problems: its detection of internal temperature is not comprehensive enough. When leakage or temperature accumulation occurs in local areas inside the distribution box, the temperature detection at a fixed location cannot fully reflect the state inside the distribution box, resulting in an incomplete understanding of the working state inside the distribution box. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a detection device for the inside of a distribution box.

[0006] The technical solution adopted by this utility model to solve its technical problem is a detection device for the inside of a distribution box, including a box body, an annular tube and a connecting column. The annular tube is arranged inside the box body. A connecting ring is arranged on one side of the outer wall of the annular tube. A connecting column is arranged on one side of the inner wall of the annular tube. A circular array of sleeves is installed on the outer wall of the connecting column. A roller is rotatably installed inside the sleeve. Magnets are embedded in both outer walls of the connecting column.

[0007] By adopting the above technical solution, the annular tube, in conjunction with the temperature sensor, can form a cyclic detection path inside the enclosure. The connecting column, along with its clamping sleeve and rollers, ensures that the temperature sensor can move smoothly and unimpeded on the outside of the annular tube for all-around detection. This achieves the purpose of measuring the temperature at multiple points inside the enclosure, and the detection data can comprehensively reflect the state inside the distribution box, providing a complete understanding of the internal working status. The clamping sleeve and rollers not only enhance the stability of the device but also reduce friction with the inner wall of the annular tube, extending its service life. The magnetic attraction between the magnet and the connecting ring ensures that the movement of the connecting column can drive the movement of the connecting ring, thus achieving the purpose of adjusting the detection position of the temperature sensor.

[0008] Specifically, a cabinet door is rotatably installed on one side of the outer wall of the cabinet body, and a control panel is provided on the outer wall of the cabinet door.

[0009] By adopting the above technical solutions, the cabinet door design makes it easy for users to open and close the cabinet for necessary maintenance and testing. The control panel provides an intuitive and easy-to-use interface, enabling users to easily control the electrical components inside the cabinet or view the test results.

[0010] Specifically, an inspection plate is provided on the upper outer wall of the box, and bolts arranged in a rectangular array are provided inside the inspection plate. The inspection plate is connected to the box by the bolts.

[0011] By adopting the above technical solution, the design of the inspection plate allows users to disassemble the ring tube as a whole without damaging the box structure, which facilitates the disassembly and maintenance of the ring tube or temperature sensor.

[0012] Specifically, ventilation pipes are inserted and installed at both the top and bottom ends of one side of the outer wall of the box, with one end of the ventilation pipe penetrating through the box and located inside it.

[0013] By adopting the above technical solution, the vent hanger is connected to an external air pump, which can deliver gas to the inside of the annular tube through the vent pipe. The amount of gas input can cause the connecting column to move inside the annular tube, and the magnetic attraction of the magnet can drive the connecting ring to move, thereby adjusting the position of the temperature sensor.

[0014] Specifically, flanges are installed on the outer walls of both ends of the annular pipe, and both ends of the annular pipe are connected to the vent pipe through the flanges respectively.

[0015] By adopting the above technical solution, the flange connection method is not only stable and reliable, but also easy to disassemble and replace, which provides convenience for subsequent maintenance. It also ensures that the gas in the vent pipe can enter the two ends of the annular pipe respectively, so that the connecting column can be driven to move back and forth inside the annular pipe according to the gas input end inside the annular pipe, ensuring that the temperature sensor can realize multi-point detection inside the box.

[0016] Specifically, a silicon steel sheet is installed on one side of the outer wall of the connecting ring, and a temperature sensor is installed on the outer wall of the silicon steel sheet.

[0017] By adopting the above technical solution, the silicon steel sheet can isolate magnetic force, avoid the magnetic force of the magnet from affecting the temperature sensor, and ensure the temperature sensor can detect the inside of the box.

[0018] Specifically, the roller is in contact with the inner wall of the annular tube, and silicone sealing rings are adhered and fixed to the outer walls on both sides of the connecting column, and the silicone sealing rings are in contact with the inner wall of the annular tube.

[0019] By adopting the above technical solution, the contact between the roller and the inner wall of the annular tube ensures the smooth movement of the connecting column in the annular tube, while the silicone sealing ring provides an additional sealing effect, ensuring the gas pressure difference between the two ends of the connecting column inside the annular tube, thereby driving the connecting column to move inside the annular tube.

[0020] The beneficial effects of this utility model are:

[0021] The present invention describes a detection device for use inside a distribution box. The magnetic attraction between the magnet and the connecting ring ensures that the movement of the connecting column can drive the movement of the connecting ring, thereby achieving the purpose of adjusting the detection position of the temperature sensor.

[0022] The present invention provides a detection device for the inside of a distribution box, which achieves the purpose of measuring the temperature at multiple points inside the box. The detection data can comprehensively reflect the state inside the distribution box and provide a complete understanding of the working state inside the distribution box.

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the present invention provides a detection device for the inside of a distribution box, comprising a box body 1, an annular tube 2, and a connecting post 3. The annular tube 2 is disposed inside the box body 1. A connecting ring 21 is disposed on one side of the outer wall of the annular tube 2. A connecting post 3 is disposed on one side of the inner wall of the annular tube 2. A circular array of sleeves 32 is installed on the outer wall of the connecting post 3. A roller 33 is rotatably installed inside the sleeve 32. Magnets 34 are embedded in both outer walls of the connecting post 3.

[0032] In use, the annular tube 2, together with the temperature sensor 22, forms a circular detection path inside the housing 1. The connecting column 3, along with its sleeve 32 and roller 33, ensures that the temperature sensor 22 can move smoothly and unobstructed outside the annular tube 2 for all-around detection. This achieves the purpose of measuring the temperature at multiple points inside the housing 1. The detection data can comprehensively reflect the state inside the distribution box, providing a complete understanding of the internal working status. The sleeve 32 and roller 33 not only enhance the stability of the device but also reduce friction with the inner wall of the annular tube 2, extending its service life. The magnetic attraction between the magnet 34 and the connecting ring 21 ensures that the movement of the connecting column 3 can drive the movement of the connecting ring 21, thus achieving the purpose of adjusting the detection position of the temperature sensor 22.

[0033] To shield housing 1, for example, such as Figure 1 As shown, a cabinet door 13 is rotatably installed on one side of the outer wall of the cabinet body 1, and a control panel is provided on the outer wall of the cabinet door 13.

[0034] When in use, the cabinet door 13 is designed to make it easy for users to open and close the enclosure 1 for necessary maintenance and testing. The control panel provides an intuitive and easy-to-use interface, allowing users to easily control the electrical components inside the enclosure 1 or view the test results.

[0035] For ease of maintenance, for example, such as Figure 1 As shown, a maintenance plate 11 is provided on the upper outer wall of the housing 1. The maintenance plate 11 is provided with bolts arranged in a rectangular array inside, and the maintenance plate 11 is connected to the housing 1 by bolts.

[0036] When in use, the design of the inspection plate 11 allows users to disassemble the annular tube 2 as a whole without damaging the structure of the housing 1, which facilitates the disassembly and maintenance of the annular tube 2 or the temperature sensor 22.

[0037] For gas delivery, exemplarily, such as Figure 1 As shown, ventilation pipes 12 are inserted and installed at both the top and bottom ends of the outer wall of one side of the box 1, with one end of the ventilation pipe 12 penetrating through the box 1 and located inside it.

[0038] In use, the ventilation hanger is connected to an external air pump, which allows gas to be delivered into the annular tube 2 through the ventilation pipe 12. The amount of gas input causes the connecting column 3 to move inside the annular tube 2, and the magnetic attraction of the magnet 34 can drive the connecting ring 21 to move, thereby adjusting the position of the temperature sensor 22.

[0039] For example, to achieve a seal, such as Figure 3 As shown, flanges 23 are installed on the outer walls of both ends of the annular pipe 2, and both ends of the annular pipe 2 are connected to the vent pipe 12 through the flanges 23 respectively.

[0040] When in use, the connection method of flange 23 is not only stable and reliable, but also easy to disassemble and replace, which provides convenience for subsequent maintenance. It also ensures that the gas in the vent pipe 12 can enter the two ends of the annular pipe 2 respectively. Thus, based on the gas input end inside the annular pipe 2, the connecting column 3 can be driven to move back and forth inside the annular pipe 2, ensuring that the temperature sensor 22 can realize multi-point detection inside the box 1.

[0041] For temperature detection, for example, such as Figure 4 As shown, a silicon steel sheet 24 is installed on one side of the outer wall of the connecting ring 21, and a temperature sensor 22 is installed on the outer wall of the silicon steel sheet 24.

[0042] When in use, the silicon steel sheet 24 can isolate the magnetic force and prevent the magnetic force of the magnet 34 from affecting the temperature sensor 22, thus ensuring that the temperature sensor 22 can detect the inside of the box 1.

[0043] To facilitate movement, for example, such as Figure 5As shown, the roller 33 is in contact with the inner wall of the annular tube 2, and silicone sealing rings 31 are glued and fixed to the outer walls on both sides of the connecting column 3. The silicone sealing rings 31 are in contact with the inner wall of the annular tube 2.

[0044] During use, the contact between the roller 33 and the inner wall of the annular tube 2 ensures the smooth movement of the connecting column 3 within the annular tube 2, while the silicone sealing ring 31 provides an additional sealing effect, ensuring the pressure difference between the gas inside the annular tube 2 and the two ends of the connecting column 3, thereby enabling the connecting column 3 to move inside the annular tube 2.

[0045] In use, the external air pump is connected to the air pipe 12 and the air pump is started. The gas enters the annular pipe 2 through the air pipe 12. Since both ends of the annular pipe 2 are connected to the air pipe 12, the gas can form a circulation inside the annular pipe 2. As the gas is input, the pressure difference on both sides of the connecting column 3 will drive it to move inside the annular pipe 2. The contact between the roller 33 and the inner wall of the annular pipe 2 ensures the stability of the connection, while the silicone sealing ring 31 provides an additional sealing effect to prevent gas leakage.

[0046] The magnetic attraction between magnet 34 and connecting ring 21 allows the movement of connecting post 3 to move connecting ring 21 and its temperature sensor 22 together. The user can adjust the gas input via the control panel to control the movement speed and position of temperature sensor 22.

[0047] Driven by the connecting ring 21, the temperature sensor 22 moves along the outside of the annular tube 2 to perform omnidirectional detection inside the chamber 1. Since the annular tube 2 forms a loop detection path inside the chamber 1, the temperature sensor 22 can cover multiple points inside the chamber 1;

[0048] Workers can open the cabinet door 13 to open the interior of the box 1, then disassemble the flange 23, disassemble the inspection plate 11, and then disassemble and maintain the annular pipe 2.

All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
