[0035] The first embodiment:

[0037] Please refer to Figure 5 - Figure 7 The upper end of the working module 1 is provided with a mounting hole, and the mounting hole is connected with a fixing device 3, which comprises a fixing cylinder 301 threadedly connected with the mounting hole, a limiting cylinder 302 coaxially fixedly connected to the inner bottom plate of the fixing cylinder 301, a connection interface 4 inserted into the limiting cylinder 302 and matched with the limiting cylinder 302, a fixing ring 303 fixedly connected to the outer wall of the connection interface 4, a fixing arm 304 fixedly connected to the outer wall of the fixing ring 303, and a prefabricated groove 305 dug in the lower end of the fixing arm 304 close to the fixing ring 303, wherein the fixing arm 304 is fixedly connected to the inner wall of the opening of the fixing cylinder 301, and the wire harness one 5 is fixedly connected to the lower end of the connection interface 4.

[0038] The working module 1 comprises a cabinet body 101 and a cabinet door 102 hingedly connected with each other, the inner wall of the cabinet body 101 is fixedly connected with a metal partition plate 103, a plurality of electric elements 104 are fixedly connected to one end of the metal partition plate 103 close to the cabinet door 102, the wires connected with the plurality of electric elements 104 penetrate through the metal partition plate 103 and extend to the side of the metal partition plate 103 away from the cabinet door 102, the detection module 2 comprises a cabinet body 201 and a cabinet door 202 hingedly connected with each other, the inner wall of the cabinet body 201 is fixedly connected with a metal partition plate 203, a plurality of detection elements 204 are fixedly connected to one end of the metal partition plate 203 close to the cabinet door 202, the wires connected with the plurality of detection elements 204 penetrate through the metal partition plate 203 and extend to the side of the metal partition plate 203 away from the cabinet door 202.

[0039] The internal space of the cabinet body 101 and the cabinet body 201 is divided into two parts by the metal partition plate 103 and the metal partition plate 203 respectively, the part close to the cabinet door 102 and the cabinet door 202 is used for installing the electric elements 104 and the detection elements 204, and the part away from the cabinet door 102 and the cabinet door 202 is used for wiring, so that the phenomenon of messy wires is not easy to appear in the cabinet body 101 and the cabinet body 201, and the modular arrangement of the switch cabinet is facilitated, and the wire bundle 5 and the wire bundle 9 each comprise a plurality of wires, which are convenient for being connected with the required electric elements 104 and detection elements 204 respectively, so as to realize the electrical connection of the cabinet body 101 and the cabinet body 201.

[0040] The quick electrical connection between the modules in the cabinet body 101 and the cabinet body 201 can be realized through the connecting interface 4 and the connecting joint 8.

[0041] In addition, the cabinet body 101 is further provided with sensors for detecting the environment, including but not limited to temperature sensors, humidity sensors and light intensity sensors, and is electrically connected with the wire bundle 5, and is electrically connected with the detection elements 204 in the cabinet body 201 through the wire bundle 5 and the connecting interface 4.

[0042] Please refer to Figure 8, in the present application, when the working module 1 and the detection module 2 need to be separated, the detection module 2 is pulled upwards, at this time, the fixed arm 304 is not subjected to horizontal force, the connecting interface 4 and the connecting joint 8 are not subjected to horizontal force, and the connecting interface 4 and the connecting joint 8 are not easy to deform. When the detection module 2 shakes or tilts in a direction during the pulling process, the connecting interface 4 and the connecting joint 8 are subjected to horizontal force, at this time, the non-rigid connecting interface 4 and the connecting joint 8 have the risk of deformation, the connecting interface 4 causes pressure to the fixed arm 304, until the fixed arm 304 is broken along the prefabricated groove 305, at this time, the connecting interface 4 as a whole will move under the driving of the detection module 2, the risk of deformation of the connecting interface 4 and the connecting joint 8 under non-vertical force is transferred from itself to the fixed arm 304, the connecting interface 4 and the connecting joint 8 are protected by the fixed arm 304, the replacement cost and difficulty are reduced, the connecting interface 4 and the connecting joint 8 are not easy to deform under external force, and the normal use is not easy to be affected.

[0043] The outer wall of the wire bundle 5 is fixedly connected with a pressure detection unit 6, and the pressure detection unit 6 is located at the lower side of the fixed cylinder 301. The upper end of the pressure detection unit 6 is embedded with a pressure sensor. The upper end of the fixed cylinder 301 is fixedly connected with a buzzer 7. The pressure detection unit 6 is signal connected with the buzzer 7. After the fixed arm 304 is broken, the connecting interface 4 will drive the wire bundle 5 to move upwards until the pressure detection unit 6 contacts the lower end of the fixed cylinder 301. The pressure sensor detects that the data changes greatly, and the buzzer 7 issues a sound alarm to remind the staff that the fixed arm 304 is damaged, and the subsequent disassembly work of the working module 1 and the detection module 2 should be careful.

[0044] The part of the wire bundle 5 in the limiting cylinder 302 is in a meandering shape.

[0045] In the present embodiment, the fixing device 3 is arranged between the working module 1 and the connecting interface 4, and the fixing device 3 is protected by the fixed arm 304. When the connecting interface 4 and the connecting joint 8 are subjected to non-vertical force, the limit horizontal force borne by the connecting interface 4 and the connecting joint 8 is controlled through the breakage of the fixed arm 304. The connecting interface 4 and the connecting joint 8 are protected by the fixed arm 304, the replacement cost and difficulty are reduced, the connecting interface 4 and the connecting joint 8 are not easy to deform, and the normal use is not easy to be affected.

[0046] The second embodiment is as follows:

[0047] Please refer to Figure 9 and Figure 11The hydraulic device 10 is arranged in the fixing cylinder 301 and located outside the limiting cylinder 302. The hydraulic device 10 comprises a shell one 1001. A split cylinder 1002 is fixedly connected to the inner top plate of the shell one 1001. The split cylinder 1002 divides the internal space of the shell one 1001 into two hydraulic chambers which are in communication with each other. A piston one 1003 and a piston two 1005 which are matched with each other are respectively and slidably connected in the two hydraulic chambers. The space below the piston one 1003 and the piston two 1005 in the shell one 1001 is filled with hydraulic oil. A plurality of driven rods 1004 are fixedly connected to the upper end of the piston one 1003. The upper end of the driven rod 1004 penetrates through the shell one 1001 and is fixedly connected with a movable ring 13. A limiting ring 12 is fixedly connected to the inner wall of the shell one 1001 and is in contact with the fixed arm 304. The inner diameter of the limiting ring 12 is matched with the outer diameter of the movable ring 13. The lower end of the cabinet two 201 is fixedly connected with a locking device 11. The locking device 11 comprises a shell two 1101. A push plate 1102 is slidably connected in the shell two 1101. The lower end of the push plate 1102 is fixedly connected with a driving rod 1104. The driving rod 1104 penetrates through the gap between the adjacent fixed arms 304, the limiting ring 12 and the shell one 1001 in sequence and is in contact with the piston two 1005. An electromagnetic ring 1103 is fixedly connected to the inner bottom plate of the shell two 1101 and is adsorbed with the push plate 1102 in the state of being electrified.

[0048] Please refer to Figure 9 - Figure 12 In the embodiment, when the working module 1 and the detection module 2 are installed, the electromagnetic ring 1103 is electrified, so that the push plate 1102 drives the driving rod 1104 to move downward. Then, in the process of plugging the connecting interface 4 and the connecting joint 8, the lower end of the driving rod 1104 pushes the piston two 1005 and drives the piston one 1003 to move upward through the hydraulic oil, so that the movable ring 13 moves to the position which is horizontal with the limiting ring 12. The limiting ring 12 and the movable ring 13 form a protection ring. In the normal use process of the working module 1 and the detection module 2, when the working module 1 and the detection module 2 are inclined, the limiting ring 12 and the movable ring 13 support the connecting interface 4, so that the fixed arm 304 is not easy to be broken and fail in advance.

[0049] When the working module 1 and the detection module 2 need to be disassembled, the electromagnetic ring 1103 is de-energized. At this time, under the action of the gravity of the movable ring 13, the piston two 1005 and the piston one 1003 are pushed to move downward, and the driving rod 1104 and the compression spring 1105 also move upward, until the position of the movable ring 13 deviates from the position of the limiting ring 12. At this time, the connecting interface 4 loses the protection of the limiting ring 12 and the movable ring 13, and the fixed arm 304 protects the connecting interface 4 from deformation.

[0050] The outer side of the driving rod 1104 is sleeved with a compression spring 1105, both ends of the compression spring 1105 are fixedly connected with the inner bottom plate of the shell two 1101 and the push plate 1102, after the electromagnetic ring 1103 is powered off, the compression spring 1105 will restore the original length, and drive the driving rod 1104 to move upwards, so that the driving rod 1104 is separated from the shell one 1001, even if the working module 1 and the detection module 2 are misaligned, the driving rod 1104 is not easy to bend and deform, and the subsequent use is not easy to be affected, the driving rod 1104 is made of magnetic material, the upper end of the piston two 1005 is fixedly connected with a magnetic block 1006 matched with the driving rod 1104, in the process of upward movement of the driving rod 1104, the piston two 1005 can be driven to move upwards, so that the phenomenon that the piston one 1003 and the piston two 1005 cannot move due to excessive hydraulic resistance and the weight of the movable ring 13 is too small is not easy to occur, and the positions of the limiting ring 12 and the movable ring 13 are easy to be misaligned.

[0051] The shell one 1001 and the shell two 1101 are made of magnetic shielding material, which reduces the influence of the use of the magnetic block 1006 and the electromagnetic ring 1103 on the electric element 104 and the detection element 204.

[0052] In particular, the upper end of the shell one 1001 and the side wall of the push plate 1102 are both drilled with through holes in the embodiment, so that the sliding of the piston one 1003, the piston two 1005 and the push plate 1102 is more smooth, and is not easy to be blocked due to air pressure.

[0053] In the embodiment, by introducing the locking device 11 and the limiting ring 12, the position of the movable ring 13 is adjusted during the installation and disassembly of the working module 1 and the detection module 2, when the working module 1 and the detection module 2 are used, the movable ring 13 is moved to the position flush with the limiting ring 12, and the limiting ring 12 and the movable ring 13 are used to support the connecting interface 4, so that the fixed arm 304 is not easy to be broken prematurely, and when the working module 1 and the detection module 2 need to be disassembled, the positions of the limiting ring 12 and the movable ring 13 are misaligned, so that the working of the fixed arm 304 is not easy to be affected. Compared with the first embodiment, although the use cost is significantly increased, the reliability of the working module 1 and the detection module 2 during use is greatly increased, so that the fixed arm 304 is not easy to be broken frequently, and frequent maintenance work is not needed.

[0054] In particular, the control and power supply method of the pressure detection unit 6, the buzzer 7 and the electromagnetic ring 1103 and other electrical structures in the application are known to those skilled in the art, so they are not disclosed in detail in the application. Those skilled in the art can reasonably design according to the prior art to meet the use needs of the application, so they are not disclosed in detail in the application.

[0055] The above merely describes preferred specific embodiments of the present application; any person skilled in the art, within the technical scope disclosed by the present application, according to the technical solutions of the present application and the improved concept thereof, makes equivalent replacements or changes, should be covered within the protection scope of the present application.
