Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to an electrical control box with a fire alarm function. Background Art

[0002] The electrical control box is a structure in which switchgear, measuring instruments, protective electrical appliances and auxiliary equipment are assembled in a closed or semi-closed metal box according to the electrical wiring requirements.

[0003] In the prior art, the temperature of electronic components in the control cabinet may continue to rise due to overvoltage or overcurrent during use. If there is no appropriate heat dissipation measure to discharge the heat in time, it is easy to cause electronic components to malfunction and cause a fire. The existing electrical control box lacks a fire alarm function, so when the electronic components malfunction and cause a fire, they cannot be dealt with in time. People cannot discover the condition of the distribution box in time, which is easy to cause greater safety hazards or accidents. A solution is proposed below to the above problems.

[0018] The following is only a preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. At the same time, it should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

[0019] See Figures 1 to 2 As shown, an electrical control box with a fire alarm function includes a box body 1. The interior of the box body 1 is divided into an electrical room at the top and a cable room at the bottom. A partition plate 2 is installed between the electrical room and the cable room. The partition plate 2 is provided with a threading hole. External cables will pass through the cable room through the threading hole on the partition plate 2 into the electrical room and connect with the electrical components in the electrical room.

[0020] Two heat dissipation holes 3 are provided on the inner wall of the box body 1, and a heat dissipation fan 4 is installed in the heat dissipation hole 3. The heat dissipation fan 4 is installed at one end of the heat dissipation hole 3 close to the outer wall of the box body 1, and a smoke sensor 5 is installed at one end of the heat dissipation hole 3 close to the inner wall of the box body 1. A controller 17 is also installed on the inner wall of the box body 1, and the controller 17 is electrically connected with the heat dissipation hole 3 and the smoke sensor 5. When the electrical control box is in operation, the heat dissipation fan 4 can be started through the controller 17 to dissipate the heat inside the box body 1. When an electronic component fails, smoke will be generated. When the heat dissipation fan 4 is in operation, the smoke will be discharged to the outside together. The smoke sensor 5 in the heat dissipation hole 3 can timely sense the smoke situation in the box body 1 and transmit the data to the controller 17 for processing in time, and the controller 17 will issue an alarm in time.

[0021] A storage room is also provided on the inner top of the box body 1, and a fire-fighting treatment component 6 for the interior of the box body 1 is provided in the storage room. When the smoke sensor 5 detects that the smoke exceeds the specified value, it will transmit data to the controller 17. The fire-fighting treatment component 6 can be started by the controller 17. The fire-fighting treatment inside the box body 1 can be performed in time by the fire-fighting treatment component 6 to prevent the situation inside the box body 1 from becoming serious.

[0022] The fire protection treatment component 6 includes a support plate 9 and a carbon dioxide storage tank 10. The support plate 9 is installed on the inner top of the box body 1. The carbon dioxide storage tank 10 is installed on the top of the support plate 9. An exhaust pipe 11 is installed on the carbon dioxide storage tank 10. An electromagnetic control valve is installed on the exhaust pipe 11. The controller 17 controls the electromagnetic control valve to open so that the gas in the carbon dioxide storage tank 10 will enter the exhaust pipe 11. The end of the exhaust pipe 11 away from the carbon dioxide storage tank 10 passes through the support plate 9. A connecting pipe 12 is installed at the bottom of the support plate 9. The exhaust pipe 11 is connected to the connecting pipe 12. A nozzle 13 is installed at the bottom of the connecting pipe 12. The gas enters the connecting pipe 12 through the exhaust pipe 11 and is sprayed out through the nozzle 13 at the bottom of the connecting pipe 12, so that the electrical components in the box body 1 can be processed.

[0023] A temperature sensor 7 and a smoke sensor 8 are also installed on the inner wall of the box body 1. The temperature sensor 7 and the smoke sensor 8 installed on the inner wall of the box body 1 can also sense the temperature inside the box body 1, so as to prevent a fire from occurring directly when the electrical components do not generate a large amount of smoke in some cases. The temperature sensor 7 can sense the fire in time, and the smoke sensor 8 can sense the smoke in time when the cooling fan 4 does not need to be turned on in severe cold weather. The temperature sensor 7 and the smoke sensor 8 are both electrically connected to the controller 17, so that when the temperature sensor 7 and the smoke sensor 8 sense an abnormal situation, the controller 17 can turn on the fire treatment component 6 in time.

[0024] Cabinet doors 14 are hinged at positions corresponding to the storage room, electrical room and cable room of the box body 1, fire-resistant sealing strips are fixed at the connections between the cabinet doors 14 and the box body 1, insulation boards 16 are installed on the opposite surfaces of the support plate 9 and the partition plate 2, and a fire-resistant rock wool layer is also installed in the inner wall of the box body 1. The fire resistance of the box body 1 can be improved by installing fire-resistant sealing strips, insulation boards 16 and fire-resistant rock wool layers.

[0025] A limit card plate 15 is also installed on the top of the support plate, and the carbon dioxide storage tank 10 is installed between the two limit card plates 15. The carbon dioxide storage tank 10 is limited by the limit card plates 15 to prevent it from shaking and bumping during transportation.

[0026] An alarm light 18 is also installed on the top of the box 1, and the alarm light 18 is electrically connected to the controller 17. When the controller 17 senses an abnormality in the box 1, it can not only turn on the fire treatment component 6 but also control the alarm light 18 to turn on in time. The alarm of the alarm light 18 on the top can promptly notify the on-site operator.

[0027] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.
