It can collect data such as current, temperature, and insulation status in real time, and realize remote monitoring and data interaction through the IoT platform. It has functions such as fault early warning, energy efficiency analysis, and automatic control, which can improve the reliability and intelligent management level of low-voltage power distribution systems. It is suitable for industrial, building and other scenarios.

[0003] According to the patent announcement number CN214958055U, which describes an intelligent low-voltage withdrawable switchgear based on ubiquitous power Internet of Things technology, this patent is a known prior art. Although this patent has the advantage of allowing personnel to easily fix parts and avoid poor circuit contact caused by shaking of the drawer, the technical solution of this patent still has the following defects in actual use: the connection position of the connecting wires is easily pulled when the switchgear is withdrawn, making it difficult to effectively protect the connection position. At the same time, it is difficult to reasonably organize a large number of connecting wires. Utility Model Content

[0004] The purpose of this utility model is to provide an intelligent low-voltage withdrawable switchgear based on the power Internet of Things technology, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent low-voltage withdrawable switchgear based on power Internet of Things technology, comprising a cabinet body and a sliding switchgear slidably connected inside the cabinet body, an extension box fixedly installed on one side of the cabinet body, a guide component provided between the sliding switchgear and the extension box, a drive component provided on the extension box, a limit component provided on the drive component, a through hole provided on the extension box, and a retracting component communicating with the through hole provided on one side of the extension box.

[0006] In a preferred embodiment, the guiding assembly includes a support slide groove fixedly installed on the cabinet body and the extension box. A support slider fixedly installed on one side of the sliding switch cabinet is slidably connected inside the support slide groove. A lower fixing frame is fixedly installed inside the support slider. A fixing rod is fixedly installed inside the support slider. A sliding block is slidably connected to the surface of the fixing rod. A limiting spring sleeved on the fixing rod is fixedly installed between the sliding block and the support slider. An upper limit frame is fixedly installed on one side of the sliding block.

[0007] In a preferred embodiment, the drive assembly includes a support sleeve fixedly mounted on the extension housing, a support rod slidably connected inside the support sleeve, a knob slidably connected to the end surface of the support rod via a keyway, a first locking block fixedly mounted on one side of the knob, and a first locking groove adapted to the first locking block being formed on the surface of the extension housing.

[0008] In a preferred embodiment, the limiting assembly includes a rotating ring fixedly mounted on the surface of a support rod, a fixed ring slidably connected to the surface of the rotating ring, a winding drum fixedly mounted on the surface of the fixed ring, a return spring fixedly mounted between the winding drum and the support rod, internal teeth formed on the inner side of the fixed ring, a support block fixedly mounted on the internal teeth, a limiting block hinged to the rotating ring and overlapping the internal teeth, and a support spring fixedly mounted between the limiting block and the support block.

[0009] In a preferred embodiment, the folding assembly includes a support frame fixedly mounted and communicating with a through hole. A folding frame is hinged inside the support frame. A limit slider is fixedly mounted on one side of the folding frame. A second locking block is slidably connected inside the limit slider. A second slot adapted to the second locking block is opened on the surface of the extension box.

[0010] In a preferred embodiment, a limiting groove is provided inside the support frame, and the limiting slider is slidably connected inside the limiting groove.

[0011] As a preferred embodiment, both the cabinet body and the extension box are provided with wiring holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This intelligent low-voltage withdrawable switchgear based on the power Internet of Things technology allows the connecting wire to be released when it is pulled out. The connecting wire will cause the winding drum to rotate in the opposite direction, which in turn causes the fixing ring and internal teeth to rotate in the opposite direction. At this time, the internal teeth and the limit block are in the same direction. This release of the connecting wire is achieved without affecting the fixed state of the support rod. Considering that the cabinet needs to be pulled out when the withdrawable switchgear is in use, the connecting wire will also be pulled out. This avoids the problem that direct pulling may easily damage the connector of the connecting wire, thus providing effective protection for the connector of the connecting wire. This intelligent low-voltage withdrawable switchgear, based on the Internet of Things (IoT) technology, allows for efficient routing of the connecting wires. By releasing the pull block, the sliding block is restrained downwards by the spring force of the limit spring, causing the upper limit frame to approach the lower fixed frame. The slots in the upper and lower fixed frames then clamp and limit the connection wires. Simultaneously, pulling the second locking block disengages it from the second slot. Rotating the limit slider rotates the retractable frame, adjusting its position within the support frame. This, combined with the bottom of the support frame, limits and fixes the connection wires, providing routing guidance and support for the wires, thus enabling efficient wire routing.

Detailed Implementation

[0015] The present invention will be further described below with reference to the embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figures 1-4 This utility model provides an intelligent low-voltage withdrawable switchgear based on power Internet of Things technology. It includes a cabinet body 1 and a sliding switchgear 2 slidably connected inside the cabinet body 1. The sliding switchgear 2 is used to install intelligent low-voltage switching components. An extension box 3 is fixedly installed on one side of the cabinet body 1, providing reasonable installation space. A guide assembly 4 is provided between the sliding switchgear 2 and the extension box 3. The guide assembly 4 includes a support groove 401 fixedly installed on the cabinet body 1 and the extension box 3, with a sliding connection inside the support groove 401. A support slider 402 is fixedly installed on one side of the sliding switch cabinet 2. A lower fixing frame 406 is fixedly installed inside the support slider 402. A fixing rod 403 is fixedly installed inside the support slider 402. A sliding block 405 is slidably connected to the surface of the fixing rod 403. A limit spring 404 sleeved on the fixing rod 403 is fixedly installed between the sliding block 405 and the support slider 402. An upper limit frame 407 is fixedly installed on one side of the sliding block 405. A pull block is fixedly installed on the top of the upper limit frame 407. Cable routing holes 9 are opened on both the cabinet body 1 and the extension box 3.

[0018] In this embodiment, when it is necessary to limit the connection wire, the pull block can be pulled up first, and then the connection wire can be placed between the lower fixed frame 406 and the upper fixed frame 407 respectively. After the connection wire is placed, the pull block can be released directly. At this time, the sliding block 405 is restricted downward by the elastic force of the limiting spring 404, thereby driving the upper fixed frame 407 to approach the lower fixed frame 406. The slots opened by the upper fixed frame 407 and the lower fixed frame 406 limit and clamp the connection wire. When the sliding switch cabinet 2 is pulled out, the sliding switch cabinet 2 drives the support slider 402, the lower fixed frame 406 and the upper fixed frame 407 to move accordingly, reducing the pulling of the connection part of the connection wire when adjusting the position of the sliding switch cabinet 2.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6The extension housing 3 is provided with a drive assembly 5, which includes a support sleeve 502 fixedly installed on the extension housing 3. A support rod 504 is slidably connected inside the support sleeve 502. A knob 505 is slidably connected to the end surface of the support rod 504 via a keyway. A first locking block 503 is fixedly installed on one side of the knob 505. A first slot 501 adapted to the first locking block 503 is opened on the surface of the extension housing 3. The drive assembly 5 is provided with a limit assembly 6, which includes components fixedly installed on the support rod 504. A rotating ring 605 is slidably connected to the surface of the rotating ring 605, and a fixed ring 603 is fixedly installed on the surface of the fixed ring 603. A return spring 601 is fixedly installed between the take-up drum 602 and the support rod 504. An internal tooth 604 is opened on the inner side of the fixed ring 603, and a support block 608 is fixedly installed on the internal tooth 604. A limiting block 606 is hinged to the rotating ring 605 and overlaps in the internal tooth 604. A support spring 607 is fixedly installed between the limiting block 606 and the support block 608.

[0020] In this embodiment, when the connecting wire needs to be wound up, the knob 505 can be pulled outward to drive the first locking block 503 to disengage from the first locking slot 501. Then, the knob 505 is rotated to drive the support rod 504 and the rotating ring 605 to rotate. At this time, the rotation direction of the rotating ring 605 will cause the limiting block 606 to push the internal teeth 604 and the fixing ring 603 to rotate, thereby driving the winding drum 602 to rotate and winding up the connecting wire on the winding drum 602. When the connecting wire is in the pulled-out state, the connecting wire will drive the winding drum 602 to rotate in the opposite direction. At this time, the winding drum 602 drives the fixing ring 603 and the internal teeth 604 to rotate in the opposite direction. At this time, the internal teeth 604 and the limiting block 606 are in the forward direction state, and the connecting wire is released without affecting the fixed state of the support rod 504.

[0021] Please see Figure 3 and Figure 7 The extension box 3 has a through hole 7. A retractable assembly 8 communicating with the through hole 7 is provided on one side of the extension box 3. The retractable assembly 8 is used to limit the wires connected to the Internet of Things. The retractable assembly 8 includes a support frame 801 fixedly installed and communicating with the through hole 7. A retractable frame 802 is hinged inside the support frame 801. A limit slider 804 is fixedly installed on one side of the retractable frame 802. A second locking block 806 is slidably connected inside the limit slider 804. A second slot 805 adapted to the second locking block 806 is provided on the surface of the extension box 3. A limit groove 803 is provided inside the support frame 801. The limit slider 804 is slidably connected inside the limit groove 803.

[0022] In this embodiment, when it is necessary to limit all connecting wires, the second locking block 806 can be pulled to disengage the second locking block 806 from the second locking slot 805. Then, the limiting slider 804 is rotated to drive the gathering frame 802 to rotate, adjusting the position of the gathering frame 802 inside the support frame 801, and cooperating with the bottom of the support frame 801 to limit and fix the connecting wires.

[0023] Working principle and usage process of this utility model: First, the external IoT connection wire can be taken from the position of the sliding switch cabinet 2, through the wiring hole 9, through the guide component 4, then overlapped on the limiting component 6, and through the retracting component 8 to connect to the external IoT. It should be noted that at this time, the connection wire between the guide component 4 and the limiting component 6 can be reserved with a large length. After the length is reserved, the pull block is released. At this time, the sliding block 405 is restricted downward by the elastic force of the limiting spring 404, thereby driving the upper limit frame 407 to approach the lower fixed frame 406. The slots opened in the upper limit frame 407 and the lower fixed frame 406 are used to limit and clamp the connection wire. Next, pull the second locking block 806 so that the second locking block 806 disengages from the second locking slot 805. Then rotate the limiting slider 804 to drive the folding frame 802 to rotate, adjust the position of the folding frame 802 inside the support frame 801, and cooperate with the bottom of the support frame 801 to limit and fix the connecting wire. After the connecting wires are separated and brought together for a limit, the knob 505 can be pulled outward to drive the first locking block 503 out of the first locking slot 501. Then, the knob 505 is rotated to drive the support rod 504 and the rotating ring 605 to rotate. At this time, the rotation direction of the rotating ring 605 will cause the limiting block 606 to push the internal tooth 604 and the fixing ring 603 to rotate, thereby driving the winding drum 602 to rotate and winding up the connecting wires on the winding drum 602. Finally, when the sliding switch cabinet 2 is pulled out, the support slider 402, lower fixing frame 406, and upper limit frame 407 move accordingly, thereby pulling the connecting wire from the position limited by the guide component 4 and pulling it out of the winding drum 602. At this time, the connecting wire will drive the winding drum 602 to rotate in the opposite direction. The winding drum 602 will then drive the fixing ring 603 and the internal teeth 604 to rotate in the opposite direction. At this time, the internal teeth 604 and the limit block 606 are in the forward direction. The connecting wire is released without affecting the fixed state of the support rod 504. When the sliding switch cabinet 2 is pushed back, the connecting wire between the guide component 4 and the limit component 6 will loosen and accumulate. At this time, the knob 505 can be pulled outward again to drive the first locking block 503 to disengage from the first locking slot 501. Then, the knob 505 can be rotated to drive the support rod 504 and the rotating ring 605 to rotate, thereby driving the winding drum 602 to rotate and rewind the connecting wire on the winding drum 602.
