Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinet detection, in particular to a local discharge detection device for a switch cabinet that is easy to use. Background Art

[0002] Partial discharge detection can reflect the electrical insulation condition inside the switch cabinet in real time, help operation and maintenance personnel understand the health of the equipment, discover and solve hidden dangers in time, and ensure the normal operation of the equipment. In addition, partial discharge detection is an effective measure to prevent equipment accidents and extend the service life of equipment. By monitoring partial discharge conditions, possible equipment failures can be predicted and corresponding measures can be taken to avoid failures and ensure the reliability and safety of the equipment.

[0003] The patent document with application number 202222160868.0 discloses an integrated sensor for detecting partial discharge of switch cabinets with primary and secondary fusion, including: a high-voltage terminal and a coupling detector; one end of the high-voltage terminal is connected to the busbar of the switch cabinet, and the other end is connected to the coupling detector; the coupling detector is used to couple with the high-voltage terminal to capture the transient current signal of the high-voltage terminal; the coupling detector is encapsulated in an insulating shell, and the insulating shell is arranged in the switch cabinet. This method can directly couple the partial discharge signal from the busbar of the switch cabinet, thereby solving the problem that the partial discharge of the switch cabinet cannot be quantitatively detected at present.

[0004] However, traditional, easy-to-use partial discharge detection equipment for switch cabinets is mostly carried manually. As a precision and valuable equipment, during the process of lifting or transporting, workers are prone to safety accidents such as equipment falling and collision due to their limited energy during long working hours, which can cause the overall device to fail to operate normally and pose a threat to personnel safety. In addition, the handling is relatively troublesome, which not only increases the workload of manual labor, but also causes certain damage to human health. For example, frequent bending can easily cause lumbar muscle strain, arthritis, etc. Utility Model Content

[0005] The utility model discloses an easy-to-use partial discharge detection device for a switch cabinet, aiming to solve the problem that most of the traditional easy-to-use partial discharge detection devices for switch cabinets are carried manually. As precision and valuable equipment, during the process of up and down carrying or transportation, due to the limited energy of workers working for a long time, safety accidents such as equipment falling and collision are prone to occur, thereby causing the overall device to fail to operate normally and posing a threat to personnel safety. In addition, the carrying is relatively troublesome, which not only increases the manual workload, but also causes certain damage to human health. For example, frequent bending over can easily cause lumbar muscle strain, arthritis, and the like.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A convenient partial discharge detection device for a switch cabinet comprises an installation box and a detection device, wherein a detection head is provided on one side of an outer wall of the detection device, a cover plate is hinged on one side of the installation box, and further comprises:

[0008] Moving mechanism: Located inside the installation box, the moving mechanism includes two installation columns and connecting rollers, a threaded groove is provided inside the installation column, the top outer wall of the installation column is connected to a first bevel gear through a bearing, the inner wall of the threaded groove is connected to a threaded rod through a thread, a mounting opening is provided on the top outer wall of the first bevel gear near the center, the threaded rod is connected to the inner wall of the mounting opening through a thread, a limit block is provided at one end of the threaded rod, a mounting plate is provided on the circumferential outer wall of the installation column, two connecting blocks are provided on the top outer wall of the installation plate near the outer walls on both sides, the connecting roller penetrates the outer walls on both sides of the two connecting blocks, and two second bevel gears are provided on the circumferential outer wall of the connecting roller, and a handle is provided at one end of the connecting roller;

[0009] The first limiting mechanism is located on the inner walls of both sides of the installation box;

[0010] Auxiliary limiting mechanism: located at the bottom of the first limiting mechanism.

[0011] When in use, according to actual carrying needs, first turn the handle clockwise to drive the connecting roller and the second bevel gear to rotate, due to the meshing action of the first bevel gear and the second bevel gear, the first bevel gear is driven to rotate in situ on the top of the mounting column, because the outer wall of the threaded rod is threadedly connected to the mounting port of the first bevel gear, and the threaded rod is limited by the auxiliary limiting mechanism at one end near the top, the threaded rod cannot rotate with the rotation of the first bevel gear, and the threaded rod will only move upward when the first bevel gear rotates, and then the first limiting mechanism drives the detection device to move upward, which is convenient for workers to move out the equipment. After using the detection device, the detection device is fixed and placed by the first limiting mechanism, and then the handle is turned counterclockwise. At this time, the threaded rod and the auxiliary limiting mechanism drive the first limiting mechanism to move downward until the entire detection device is completely stored inside the installation box. This device reduces the burden of workers in carrying, avoids damage to the detection device to a large extent, and improves the safety of use.

[0012] In a preferred solution, the first limiting mechanism includes two fixed plates, a support plate is provided inside the installation box and on the top outer wall of the auxiliary limiting mechanism, the limit block is installed on the bottom outer wall of the support plate, the two fixed plates are respectively installed on the top outer wall of the support plate close to the outer walls on both sides, one side outer wall of one of the fixed plates is provided with three fixing grooves, the inner wall of the fixing groove is provided with a reset spring, a limit plate is provided at one end of the reset spring, one side outer wall of one of the fixed plates is provided with three limit sleeves, and the limit sleeves are suitable for the detection head.

[0013] When in use, first place the detection device on the upper surface of the support plate and push it to the right, thereby driving the limit plate to move to the right and squeezing the reset spring, and then release the rightward pushing force. At this time, under the action of the elastic force of the reset spring, one side of the detection head is stuck in the limit sleeve, limiting the entire detection device and the detection head to prevent the detection device and the detection head from shaking and shifting in the installation box during transportation, which may cause damage to the detection device and affect the accuracy of the detection.

[0014] In a preferred solution, the auxiliary limiting mechanism includes two connecting plates, the top outer wall of the connecting plate is provided with two supporting columns, the mounting column is located between the two supporting columns, the supporting column passes through the bottom inner wall of the mounting box, and the circumferential outer wall of the supporting column is provided with a limiting ring and a mounting tube, the limiting ring is located at the bottom of the mounting tube, a connecting rod is provided between the mounting tube and the limiting block, and a fixing rod is provided between two adjacent support columns.

[0015] When the threaded rod moves up and down, due to the connection between the limit block, the connecting rod and the two mounting tubes, the mounting tube will be synchronously driven to move up and down on the outer wall of the support column, thereby driving the support plate to move up and down, thereby realizing the up and down transportation of the detection device, reducing the manpower burden, and the set limit ring provides support and limiting for the mounting tube.

[0016] As can be seen from the above, a convenient partial discharge detection device for a switch cabinet includes an installation box and a detection device, a detection head is provided on one side of the outer wall of the detection device, a cover plate is hinged on one side of the installation box, and further includes:

The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0026] The utility model discloses an easy-to-use partial discharge detection device for switch cabinets, which is mainly used for traditional easy-to-use partial discharge detection devices for switch cabinets, which are mostly carried manually. As precision and valuable equipment, during the process of up and down carrying or transportation, workers have limited energy due to long-term work, which may easily cause safety accidents such as equipment falling and collision, thereby causing the overall device to fail to operate normally and posing a threat to personnel safety. In addition, the transportation is relatively troublesome, which not only increases the workload of manual labor, but also causes certain damage to human health. For example, frequent bending over may easily cause lumbar muscle strain, arthritis, etc.

[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A convenient partial discharge detection device for a switch cabinet includes an installation box 1 and a detection device 11, a detection head 10 is provided on one side of the outer wall of the detection device 11, a cover plate 2 is hinged on one side of the installation box 1, and further includes:

[0028] Moving mechanism: Located inside the installation box 1, the moving mechanism includes two installation columns 4 and a connecting roller 22. A threaded groove is provided inside the installation column 4. The top outer wall of the installation column 4 is connected to the first bevel gear 16 through a bearing. The inner wall of the threaded groove is connected to the threaded rod 18 through a thread. A mounting opening is provided on the top outer wall of the first bevel gear 16 near the center. The threaded rod 18 is connected to the inner wall of the mounting opening through a thread. A limit block 20 is provided at one end of the threaded rod 18. A mounting plate 21 is provided on the circumferential outer wall of the installation column 4. Two connecting blocks are provided on the top outer wall of the installation plate 21 near the outer walls on both sides. The connecting roller 22 runs through the outer walls on both sides of the two connecting blocks, and the circumferential outer wall of the connecting roller 22 is provided with two second bevel gears 17. A handle 12 is provided at one end of the connecting roller 22.

[0029] The first limiting mechanism is located on the inner walls of both sides of the installation box 1;

[0030] Auxiliary limiting mechanism: located at the bottom of the first limiting mechanism.

[0031] The mounting plate 21 is an “L”-shaped structure, which is convenient for fixing on the surface of the mounting column 4 , and at the same time supports, limits and fixes the connecting block, the second bevel gear 17 and the connecting roller 22 .

[0032] In actual use, the first bevel gear 16 and the second bevel gear 17 are of the same size and mesh with each other.

[0033] Specifically, when in use, according to actual carrying needs, the handle 12 is first rotated clockwise, thereby driving the connecting roller 22 and the second bevel gear 17 to rotate. Due to the meshing action of the first bevel gear 16 and the second bevel gear 17, the first bevel gear 16 is driven to rotate in situ at the top of the mounting column 4. Since the outer wall of the threaded rod 18 is threadedly connected to the mounting port of the first bevel gear 16, and the threaded rod 18 is limited by the auxiliary limiting mechanism at one end near the top, the threaded rod 18 cannot rotate with the rotation of the first bevel gear 16, and the threaded rod 18 will only move upward when the first bevel gear 16 rotates. Then the first limiting mechanism drives the detection device 11 to move upward, which is convenient for workers to move out the equipment. After using the detection device 11, the detection device 11 is fixed and placed by the first limiting mechanism, and then the handle 12 is rotated counterclockwise. At this time, the threaded rod 18 and the auxiliary limiting mechanism drive the first limiting mechanism to move downward until the entire detection device 11 is completely stored inside the installation box 1. This device reduces the burden of workers in carrying, prevents the detection device 11 from being damaged during transportation, and improves the safety of use.

[0034] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the first limiting mechanism includes two fixed plates 8, a support plate 15 is provided on the top outer wall of the auxiliary limiting mechanism and located inside the installation box 1, and the limiting block 20 is installed on the bottom outer wall of the support plate 15. The two fixed plates 8 are respectively installed on the top outer wall of the support plate 15 near the outer walls on both sides. Three fixing grooves are opened on the outer wall of one side of one of the fixed plates 8, and a reset spring 24 is provided on the inner wall of the fixing groove. A limiting plate 23 is provided at one end of the reset spring 24, and three limiting sleeves 9 are provided on the outer wall of one side of one of the fixed plates 8, and the limiting sleeve 9 is suitable for the detection head 10.

[0035] Among them, sliders 25 are provided on the outer walls of both sides of the support plate 15, and slide grooves 7 are opened on the inner walls of both sides of the installation box 1. The sliders 25 are slidably connected to the inner walls of the slide grooves 7. This arrangement improves the stability of the support plate 15 when it moves up and down, and prevents the support plate 15 from shaking greatly during the up and down movement, thereby causing certain damage to the detection device 11.

[0036] Specifically, when in use, the detection device 11 is first placed on the upper surface of the support plate 15 and pushed to the right, thereby driving the limit plate 23 to move to the right and squeeze the reset spring 24, and then the rightward pushing force is released. At this time, under the action of the elastic force of the reset spring 24, one side of the detection head 10 is stuck in the limit sleeve 9, and the entire detection device 11 and the detection head 10 are limited to prevent the detection device 11 and the detection head 10 from shaking and shifting in the installation box 1 during transportation, thereby causing damage to the detection device 11, and then affecting the accuracy of the detection.

[0037] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the auxiliary limiting mechanism includes two connecting plates 5, the top outer wall of the connecting plate 5 is provided with two support columns 3, the mounting column 4 is located between the two support columns 3, the support column 3 passes through the bottom inner wall of the mounting box 1, and the circumferential outer wall of the support column 3 is provided with a limiting ring 13 and a mounting tube 14, the limiting ring 13 is located at the bottom of the mounting tube 14, a connecting rod 19 is provided between the mounting tube 14 and the limiting block 20, and a fixing rod is provided between two adjacent support columns 3.

[0038] The bottom outer walls of the two connecting plates 5 are each provided with two universal wheels 6, which facilitates pushing the installation box 1 and the detection device 11 to move to a designated position for detection.

[0039] Specifically, when the threaded rod 18 moves up and down, due to the connection between the limit block 20, the connecting rod 19 and the two mounting tubes 14, the mounting tube 14 will be synchronously driven to move up and down on the outer wall of the support column 3, thereby driving the support plate 15 to move up and down, thereby realizing the up and down transportation of the detection device 11, reducing the manpower burden, and the set limit ring 13 provides support and limiting functions for the mounting tube 14.

[0040] Working principle: When in use, according to actual carrying needs, first turn the handle 12 clockwise to drive the connecting roller 22 and the second bevel gear 17 to rotate. Due to the meshing action of the first bevel gear 16 and the second bevel gear 17, the first bevel gear 16 is driven to rotate in situ at the top of the mounting column 4. Since the outer wall of the threaded rod 18 is threadedly connected to the mounting port of the first bevel gear 16, and the threaded rod 18 is limited by the auxiliary limiting mechanism at one end near the top, the threaded rod 18 cannot rotate with the rotation of the first bevel gear 16. The threaded rod 18 will only move upward when the first bevel gear 16 rotates. Then the first limiting mechanism drives the detection device 11 to move upward, which is convenient for workers to move out the equipment. After using the detection device 11, the detection device 11 is fixed and placed by the first limiting mechanism, and then the handle 12 is turned counterclockwise. At this time, the threaded rod 18 and the auxiliary limiting mechanism drive the first limiting mechanism to move downward until the entire detection device 11 is completely stored inside the mounting box 1.

[0041] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
