Description
Technical Field
[0001] The utility model relates to the technical field of electric power equipment, in particular to an integrated primary and secondary integrated ring network switch cabinet with a self-fire extinguishing function. Background Art
[0002] With the rapid development of smart grid technology, ring network switchgear, as the core equipment in the distribution system, is undergoing a profound transformation in integration and intelligence. The introduction of primary and secondary fusion technology marks an important step forward in the functional integration of ring network switchgear, realizing the deep integration and efficient coordination of monitoring, control and protection functions. Through highly integrated electronic components and intelligent algorithms, this technology significantly improves the ring network switchgear's real-time perception of the grid operation status, rapid fault diagnosis and precise control capabilities, providing a solid guarantee for the safe and stable operation of the smart grid. However, while this technological innovation brings many conveniences, it is also accompanied by an increase in the risk of electrical fires, and puts forward more stringent requirements on the fire safety performance of the ring network switchgear.
[0003] In the process of implementing the present invention, the inventors discovered that the prior art has at least the following problems:
[0004] Due to the compact internal space of the ring main unit and the dense arrangement of electrical components, fires can easily occur once abnormal conditions such as overload, short circuit or insulation failure occur. Traditional fire-fighting methods, such as relying on external manually operated fire extinguishers, often respond slowly to such emergencies and find it difficult to effectively intervene in the early stages of a fire, thus missing the best opportunity to extinguish the fire. In addition, the current external fire-fighting devices not only take up a lot of space and are difficult to seamlessly integrate with the compact structure of the ring main unit, affecting the overall compactness and aesthetics of the equipment, but may also reduce their actual fire-fighting efficiency due to improper installation location.
[0005] Therefore, the above technical problems need to be solved. Utility Model Content
[0006] In order to overcome the deficiencies of the prior art, the present invention proposes an integrated primary-secondary integrated ring network switch cabinet with a self-extinguishing function, which solves the problems raised in the above-mentioned background technology.
[0007] In order to solve the above technical problems, the basic technical solutions proposed by the present invention are as follows:
[0008] An integrated primary and secondary integrated ring network switch cabinet with self-extinguishing function, comprising a ring network switch cabinet body and two fire extinguishing mechanisms respectively mounted on the two outer side walls of the ring network switch cabinet body.
[0009] The fire extinguishing mechanism includes a fire extinguisher suspended by a mounting frame, and an actuator mounted on the upper portion of the mounting frame for opening the fire extinguisher valve assembly. The output end of the fire extinguisher valve is fixedly connected to a hose, and the other end of the hose is installed through the side wall of the ring network switch cabinet body and communicates with the interior of the ring network switch cabinet body.
[0010] The execution unit includes a U-shaped bending part and a pin pulling assembly for pulling out the fire extinguisher safety pin and a pressing assembly for pressing the fire extinguisher handle, both of which are assembled on the outer panel of the U-shaped bending part, and a limit switch provided under the fire extinguisher handle.
[0011] The pin pulling assembly includes an electric push rod, an L-shaped bracket and a reset spring. The L-shaped bracket is fitted on the outer wall of the electric push rod. The output end of the electric push rod is coaxially mounted with an end plate and a blocking rod that can pass through the safety pin pull ring hole is vertically provided on the end plate. One end of the reset spring is fixedly mounted on the folded surface of the L-shaped bracket by a screw, and the other end of the reset spring is hung on the safety pin pull ring hole.
[0012] The pressing assembly includes a servo motor, the output end of the servo motor passes through the outer panel of the U-shaped bending part and a pressing wheel is eccentrically installed above the fire extinguisher pressure handle.
[0013] Preferably, the mounting bracket consists of a fixing plate mounted against the side wall of the ring main switch cabinet body, a bracket perpendicularly mounted at the bottom of the fixing plate's outer wall for the fire extinguisher to fit on, and a U-shaped fixing strap mounted in the middle of the fixing plate's outer wall for retaining the fire extinguisher's tank. This mounting bracket not only ensures the stable placement of the fire extinguisher but also allows the fire extinguishing mechanism to fit snugly against the outer wall of the ring main switch cabinet body, eliminating the need for additional space and maintaining the overall compactness and aesthetics of the equipment.
[0014] Preferably, an annular groove is coaxially formed on the outer wall of the pressure wheel to accommodate the tail end of the fire extinguisher's pressure handle. The pressure wheel serves as the actuator of the pressing assembly that directly contacts the fire extinguisher's pressure handle. The annular groove formed on its outer wall can limit the pressure handle and further ensure a stable pressing effect.
[0015] Preferably, the device further includes a nozzle with a conical flared structure, located inside the ring network switch cabinet body and connected to the hose output end. The hose is connected to the nozzle inside the ring network switch cabinet body, and the nozzle adopts a conical flared structure. This optimizes the spraying effect of the fire extinguishing agent, ensuring that the fire extinguishing agent covers a wider area of the fire source. Furthermore, it provides a further limiting structure to prevent the hose output end from separating from the side wall of the ring network switch cabinet body.
[0016] The beneficial effects of the utility model are:
[0017] The technical solution of the present invention is to modularly integrate the fire extinguishing mechanism on the outer wall of the ring network cabinet. At the same time, with the help of the pin pulling assembly and the pressing assembly, with the cooperation of the fire extinguisher, timely intervention can be carried out in the early stage of the fire. Compared with traditional manual fire extinguishing and external fire extinguishing devices, it can not only achieve a fast-response fire extinguishing effect, but also ensure the overall compactness and aesthetics of the equipment.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0036] See also Figure 1-8 The utility model provides a technical solution: an integrated primary and secondary integrated ring network switch cabinet with a self-extinguishing function, comprising a ring network switch cabinet main body 100 and two fire extinguishing mechanisms 200 respectively mounted on the two outer side walls of the ring network switch cabinet main body 100, the fire extinguishing mechanism 200 comprising a fire extinguisher 220 suspended by a mounting frame 210, and an execution unit 230 mounted on the upper part of the mounting frame 210 for opening the valve assembly of the fire extinguisher 220, the output end of the valve of the fire extinguisher 220 is fixedly connected to a hose 240, the other end of the hose 240 is installed through the side wall of the ring network switch cabinet main body 100 and is connected to the interior of the ring network switch cabinet main body 100, the execution unit 230 comprises a U-shaped bending part 2310 and a pin pulling assembly 2320 for pulling out the safety pin of the fire extinguisher 220 and a pressure handle for the fire extinguisher 220, both of which are mounted on the outer side panels of the U-shaped bending part 2310. The pressing component 2330 and the limit switch 2340 provided under the pressure handle of the fire extinguisher 220, the pin pulling component 2320 include an electric push rod 2321, an L-shaped bracket 2322 and a return spring 2323. The L-shaped bracket 2322 is fitted on the outer wall of the electric push rod 2321. The output end of the electric push rod 2321 is coaxially mounted with an end plate 2324 and a baffle 2325 is vertically provided on the end plate 2324 and can pass through the safety pin pull ring hole. One end of the return spring 2323 is fixedly mounted on the folding surface of the L-shaped bracket 2322 by a screw 2326, and the other end of the return spring 2323 is hung on the safety pin pull ring hole. The pressing component 2330 includes a servo motor 2331. The output end of the servo motor 2331 passes through the outer panel of the U-shaped bending part 2310 and a pressure wheel 2332 is eccentrically mounted above the pressure handle of the fire extinguisher 220.
[0037] Based on the above-mentioned structure, the integrated primary and secondary integrated ring network switch cabinet with self-extinguishing function is composed of a ring network switch cabinet body 100 and two fire extinguishing mechanisms 200. In normal working state, the ring network switch cabinet body 100 performs the core function of its power distribution system, while the fire extinguishing mechanism 200 is in standby state and does not interfere with the normal operation of the ring network switch cabinet. The fire extinguishing mechanism 200 is firmly suspended on the outer wall of the ring network switch cabinet body 100 through the mounting frame 210, and the valve assembly of the fire extinguisher 220 is connected to the ring network switch cabinet body 100 through the hose 240. The interior of the cabinet body 100 is connected to ensure that the fire extinguishing agent can be quickly sprayed into the interior of the ring network switch cabinet body 100 when needed. When a fire is caused by abnormal conditions such as overload, short circuit or insulation failure inside the ring network switch cabinet body 100, the execution unit 230 of the fire extinguishing mechanism 200 will respond quickly. Specifically, the pin pulling assembly 2320 in the execution unit 230 is first started, and the electric push rod 2321 contracts to drive the end plate 2324 to move backward, so that the blocking rod 2325 is disengaged from the pull ring hole of the safety pin of the fire extinguisher 220. At the same time, the return spring 2323 is elastic. The safety pin is pulled out under the action of force. This action releases the locked state of the fire extinguisher 220 and prepares it for opening. Then, the pressing component 2330 starts to work, and the servo motor 2331 drives its output end to rotate. Since the pressing wheel 2332 is eccentrically installed on the output end of the servo motor 2331, the pressing wheel 2332 will make a circular motion and gradually press down the pressure handle of the fire extinguisher 220. When the pressure handle is pressed down to the predetermined position, the limit switch 2340 is triggered, and the servo motor 2331 stops moving. At this time, the valve of the fire extinguisher 220 is opened. When the fire is started, the fire extinguishing agent is quickly sprayed into the interior of the ring network switch cabinet main body 100 through the hose 240 to extinguish the fire source. The integrated primary and secondary fusion ring network switch cabinet with self-fire extinguishing function integrates the fire extinguishing mechanism 200 into the outer wall of the ring network cabinet in a modular manner. At the same time, with the help of the pin puller component 2320 and the pressing component 2330, with the cooperation of the fire extinguisher 220, timely intervention can be carried out in the early stage of the fire. Compared with traditional manual fire extinguishing and external fire extinguishing devices, it can not only achieve a fast-response fire extinguishing effect, but also ensure the overall compactness and aesthetics of the equipment.
[0038] It should be noted that the present invention only describes the function of the fire extinguishing mechanism 200, and does not involve related detection sources. In specific applications, the ring network switch cabinet body 100 is usually equipped with an environmental detection module to detect fire signals, such as smoke detectors, temperature detectors, etc. Once the smoke concentration or temperature in the ring network switch cabinet body 100 exceeds the preset value, a signal will be sent to the control system, and the control system will send an instruction to the fire extinguishing mechanism 200. This process is an existing mature technology and is not the innovation of the present invention, and is not shown in the accompanying drawings. At the same time, the ring network switch cabinet body 100 in the present invention is integrated with existing mature technology, and its specific structure and working principle are not the innovation of the present invention, so it is not shown in the accompanying drawings. The protection scope of the present invention is only for the fire extinguishing related structural features clearly defined in the claims. In addition, the fire extinguisher 220 in the present invention can clean gas fire extinguishing agents, such as heptafluoropropane, which has no residue, is non-conductive, and does not damage the equipment.
[0039] Furthermore, the mounting frame 210 is composed of a fixing plate 2110 installed in contact with the side wall of the ring network switch cabinet body 100, a bracket 2120 vertically arranged at the bottom of the outer wall of the fixing plate 2110 for the fire extinguisher 220 to be accommodated and placed, and a U-shaped fixing belt 2130 installed in the middle of the outer wall of the fixing plate 2110 for limiting the tank body of the fire extinguisher 220.
[0040] Furthermore, an annular groove 2333 is coaxially formed on the outer wall of the pressure wheel 2332 to accommodate the tail end of the pressure handle of the fire extinguisher 220 .
[0041] Furthermore, it also includes a nozzle 2410 which is arranged inside the ring network switch cabinet body 100 and is connected to the output end of the hose 240 and has a conical expansion structure.
[0042] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and any modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are for convenience of description only and do not constitute any limitation to the present invention.
