Description

Technical Field

[0001] This utility model relates to the field of electrical box technology, and in particular to an electrical box for electrical equipment. Background Technology

[0002] When electrical wires pass through conduits, electrical boxes are used as transitions at the joints where the wires are long or the conduits need to bend. The conduits are connected to the electrical boxes, and the wires inside the conduits are connected in the electrical boxes, which serves to connect and protect the wires.

[0003] Currently, existing electrical boxes (such as patent publication number: CN214626245U) disclose an electrical box for electrical equipment. By setting up a movable block, a binding ring, and a binding groove, it is convenient to fix the wire harness at the wire harness hole while preventing damage to the wire harness caused by excessive tightening, thus improving the practicality of the box. By setting up heat dissipation holes, a limiting groove, a baffle, and fixing teeth, the size of the heat dissipation holes can be adjusted and closed, which helps to prevent dust and rainwater from entering the interior of the box when not in use, thus preventing damage to the wire harness and safety issues, thereby improving the safety of the box.

[0004] In the aforementioned patent, the electrical box contains a large number of electrical components. Aging, dampness, or mechanical damage to the wiring insulation can cause direct contact between phase wires or between a phase wire and the ground wire, generating electric arcs and high temperatures, which can lead to a fire. This fire can directly ignite the components inside the electrical box, causing the fire to spread. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an electrical box for electrical equipment, which solves the technical problem that the electrical box contains a large number of electrical components, and the aging, dampness or mechanical damage of the wiring insulation can lead to direct contact between phase wires or between phase wires and ground wires, generating electric arcs and high temperatures, which can cause fires, directly ignite the components inside the electrical box, and cause the fire to spread.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An electrical box for an electrical device includes a box body and a partition, a retaining frame is fixedly installed at the bottom of the box body, a controller is provided inside the box body, and further includes;

[0008] Two smoke sensors are fixedly installed on both sides of the partition, and a flow guide plate is fixedly installed on both sides of the partition. At least two nozzles are fixedly installed inside each flow guide plate.

[0009] Each of the aforementioned indwelling frames is fixedly installed with a connector inside, and the indwelling frame is provided with a storage tank that mates with the connector. A solenoid valve is installed inside the connector.

[0010] Preferably, a positioning sleeve is slidably installed inside the indwelling frame, and the positioning sleeve has a split structure;

[0011] Two return rods are fixedly installed inside the positioning sleeve, and each return rod is equipped with a reset spring.

[0012] Preferably, a support is fixedly installed at the side end of the positioning sleeve, and a plug rod is rotatably installed inside the support;

[0013] An air supply pipe is fixedly installed inside the box, and the two ends of the air supply pipe are respectively connected to a connector and a partition.

[0014] Each of the smoke sensors is connected in series via a wire harness, and a storage slot is provided on the side of the housing.

[0015] Compared with the prior art, the present invention has the following beneficial effects;

[0016] In this invention, the storage tank stores carbon dioxide. After the smoke sensor detects smoke, it controls the solenoid valve inside the connector to open, and the carbon dioxide is sprayed out from the nozzle through the gas delivery pipe to extinguish the fire. This can quickly reduce the oxygen concentration at the ignition point, inhibit the combustion reaction, extinguish fires caused by short circuits in electrical equipment in a timely manner, prevent the fire from spreading, and ensure the safety of electrical equipment.

[0017] In this invention, after the storage tank and the connector are connected, the positioning sleeve is pulled to extend and retract, so that the extension and retraction of the positioning sleeve squeezes the side end of the storage tank. This allows the storage tank and the connector to be connected and firmly squeezed and fixed in the retention frame, ensuring that the storage tank is stable in position during normal operation and facilitating installation, disassembly and maintenance. The positioning sleeve has a split structure for easy extension and retraction, and the return spring inside the return rod provides a reverse pulling force to assist in positioning. After the connector is flipped, it is inserted into the retention frame to provide support and positioning. Attached Figure Description

[0024] This application provides an electrical box for electrical equipment, effectively solving the problem that the electrical box contains a large number of electrical components, and that aging, dampness, or mechanical damage to the wiring insulation can lead to direct contact between phase wires or between a phase wire and the ground wire, generating electric arcs and high temperatures, which can cause fires and directly ignite the components inside the electrical box, leading to the spread of the fire. The storage tank stores carbon dioxide, and when a smoke sensor detects smoke, it controls the opening of a solenoid valve in the connector, allowing carbon dioxide to be sprayed out from the nozzle through the gas pipe to extinguish the fire. This can quickly reduce the oxygen concentration at the ignition point, inhibit the combustion reaction, and promptly extinguish fires caused by short circuits in electrical equipment, preventing the fire from spreading and ensuring the safety of the electrical equipment.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that a large number of electrical components are concentrated inside the electrical box, and the aging, dampness, or mechanical damage of the wiring insulation leads to direct contact between phase wires and between phase wires and ground wires, generating electric arcs and high temperatures, which can cause fires, directly igniting the components inside the electrical box and causing the fire to spread. The overall idea is as follows:

[0027] To address the problems existing in the prior art, this utility model provides an electrical box for electrical equipment, including a box body 11 and a partition 12. A placement frame 17 is fixedly installed at the bottom of the box body 11. A controller is installed inside the box body 11. The interior of the box body 11 is divided by two partitions 12, and the electrical equipment is installed inside the box body 11.

[0028] Two smoke sensors 14 are fixedly installed on both sides of the partition 12. A guide plate 15 is fixedly installed on both sides of the partition 12. At least two nozzles 16 are fixedly installed inside each guide plate 15. Smoke sensors 14 are installed on both sides of the smoke sensors 14. The smoke sensors 14 can detect the generation of smoke on one side. When smoke is detected, the smoke sensor 14 controls the solenoid valve inside the connector 24 to open, allowing the carbon dioxide stored in the storage tank 23 to enter the interior of the partition 12 through the gas pipe 13 and be sprayed out through the nozzle 16 on one side. In the event of a short circuit fire, the fire can be extinguished quickly to prevent the spread of the fire.

[0029] Each indwelling frame 17 is fixedly installed with a connector 24 inside. Inside the indwelling frame 17, there is a storage tank 23 that is connected to the connector 24. A solenoid valve is installed inside the connector 24. One end of the storage tank 23 is connected to the connector 24. The storage tank 23 stores carbon dioxide. At the same time, the solenoid valve inside the connector 24 is in the closed state.

[0030] A positioning sleeve 18 is slidably installed inside the indwelling frame 17. The positioning sleeve 18 has a split structure. After the storage tank 23 is connected to the connector 24, the positioning sleeve 18 is pulled to extend and retract, so that the positioning sleeve 18 extends and retracts to squeeze the side end of the storage tank 23.

[0031] Two return rods 19 are fixedly installed inside the positioning sleeve 18. Each return rod 19 is equipped with a return spring. During the stretching of the positioning sleeve 18, a pulling force is generated on the return rod 19. Since the return rod 19 is equipped with a return spring, the spring stretching generates a reverse pulling force on the positioning sleeve 18.

[0032] A support 22 is fixedly installed on the side end of the positioning sleeve 18. An insert rod 21 is rotatably installed inside the support 22. By stretching the positioning sleeve 18, the insert rod 21 is flipped so that it is in a vertical state. The end of the insert rod 21 is inserted into the inside of the retention frame 17. The insert rod 21 supports the positioning sleeve 18, so that the positioning sleeve 18 is in a state of compression and fixation to the storage tank 23.

[0033] A gas supply pipe 13 is fixedly installed inside the box 11. The two ends of the gas supply pipe 13 are connected to the connector 24 and the partition 12 respectively. The partition 12 and the gas supply pipe 13 are in a continuous state. Once the solenoid valve inside the connector 24 is opened, carbon dioxide will enter the interior of the guide plate 15 through the gas supply pipe 13 and quickly extinguish the fire inside the box 11.

[0034] Each smoke sensor 14 is connected in series via a wire harness, and a storage slot is provided on the side of the housing 11.

[0035] Working principle:

[0036] The first step involves aligning the storage tank 23 with the connector 24 inside the indwelling frame 17, and then pulling the positioning sleeve 18. The positioning sleeve 18 slides and extends within the indwelling frame 17. During this process, the return rod 19 inside the positioning sleeve 18 is subjected to tension. Due to the action of the return spring inside the return rod 19, the spring is stretched, which in turn generates a reverse tension on the positioning sleeve 18. When the positioning sleeve 18 is stretched to the appropriate position, the connector 21 is flipped so that it is in a vertical state. The end of the connector 21 is inserted into the indwelling frame 17, thereby supporting the positioning sleeve 18 and pressing the side end of the storage tank 23, so that the storage tank 23 is in a compressed and fixed state. At this time, the solenoid valve inside the connector 24 is in a closed state, and the carbon dioxide inside the storage tank 23 will not flow out.

[0037] Smoke sensors 14 are installed on the side ends of partitions 12, and two smoke sensors 14 are installed on both side ends of each partition 12. The smoke sensors 14 are connected in series by wire harnesses. A baffle plate 15 is also fixedly installed on the side ends of partitions 12. At least two nozzles 16 are fixedly installed inside each baffle plate 15. An air supply pipe 13 is fixedly installed inside the housing 11, and its two ends are connected to the connector 24 and the partition 12 respectively, so that the partition 12 and the air supply pipe 13 are in a through state.

[0038] The second step involves the electrical equipment operating within the housing 11 during normal operation. The smoke sensor 14 continuously monitors the surrounding environment. When the electrical equipment catches fire due to a short circuit or other reasons, producing smoke, the smoke sensor 14 detects the smoke. Since the smoke sensor 14 can detect smoke on a single side, as long as the smoke sensor 14 detects smoke, subsequent fire extinguishing actions can be triggered. After detecting smoke, the smoke sensor 14 sends an electrical signal. Upon receiving the signal from the smoke sensor 14, the controller drives the solenoid valve to open. At this time, the carbon dioxide stored in the storage tank 23, under its own pressure, enters the gas supply pipe 13 through the channel connected to the connector 24. The carbon dioxide enters the interior of the partition 12 through the gas supply pipe 13, then flows into the guide plate 15, and finally is sprayed out from the nozzle 16 inside the guide plate 15. The sprayed carbon dioxide covers the fire area, rapidly reducing the oxygen concentration around the ignition point, inhibiting the combustion reaction, and quickly carrying out fire extinguishing operations to prevent the fire from spreading.

[0039] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
