Description

Technical Field

[0001] The utility model relates to the technical field of dry powder spraying equipment, in particular to an efficient dry powder spraying equipment for electrical fire extinguishing. Background Art

[0002] Electrical equipment is widely used in various fields. From industrial production to daily life, the normal operation of electrical systems plays a crucial role in social operation. However, during the operation of electrical equipment, due to various factors such as aging of circuits, overload, short circuit, and equipment failures, fires are extremely likely to occur. Compared with ordinary fires, electrical fires have a series of remarkable characteristics, making their extinguishment much more difficult.

[0003] However, traditional fire extinguishing equipment is difficult to quickly and accurately locate the fire source, resulting in a delay in the fire extinguishing opportunity. In electrical fires, the ignition point often spreads due to the spread of the fire. The single and fixed spraying method of traditional equipment cannot effectively cover the expanded fire area, making some ignition points not extinguished in time, and the fire is likely to reignite, making it difficult to achieve a comprehensive and efficient extinguishment of electrical fires. Therefore, we propose an efficient dry powder spraying equipment for electrical fire extinguishing to solve the above problems. Summary of the Utility Model

Specific embodiments

[0023] The following further elaborates on this application in conjunction with the attached Figures 1-4 for a more detailed description.

[0024] The embodiments of this application disclose an efficient electrical fire extinguishing dry powder spraying device.

[0025] Referring to Figures 1-4 , an efficient electrical fire extinguishing dry powder spraying device includes a mounting frame 101. A dry powder fire extinguishing agent tank 102 is installed at the top of the mounting frame 101. A solenoid valve 103 is installed at the discharge port of the dry powder fire extinguishing agent tank 102. A hose 104 is installed at the discharge port. One end of the hose 104 is installed with a nozzle 105. A housing 201 is fixedly installed on one side inner wall of the mounting frame 101. A guiding seat 202 is fixedly installed on one side of the housing 201. A moving seat 203 is slidably sleeved on the guiding seat 202. A box body 204 is fixedly installed at the bottom of the moving seat 203. A rotating mechanism is provided between the box body 204 and the nozzle 105. The rotating mechanism includes a rotating shaft 401 and a rotating seat 402. The same rotating shaft 401 is rotatably installed on both side inner walls of the box body 204. One end of the rotating shaft 401 extends to the outside of the box body 204 and is fixedly installed with a rotating seat 402. And the nozzle 105 is fixedly installed on the rotating seat 402 through a detachable structure.

[0026] In this embodiment, the same threaded rod 301 is rotatably installed on both side inner walls of the mounting frame 101, and the moving seat 203 is threadedly sleeved on the threaded rod 301. This design enables the moving seat 203 to move stably left and right under the drive of the threaded rod 301, accurately adjusting the position of the nozzle 105 in the horizontal direction, so as to align with the fire source, greatly improving the accuracy of fire extinguishing.

[0027] In this embodiment, a rotating motor 302 is installed on the bottom inner wall of the housing 201. A transmission mechanism is provided between the rotating motor 302 and the threaded rod 301. The transmission mechanism includes a driving bevel gear 303 and a driven bevel gear 304. The driving bevel gear 303 is fixedly installed on the output shaft of the rotating motor 302, and the driven bevel gear 304 is fixedly installed on the threaded rod 301, and the driving bevel gear 303 meshes with the corresponding driven bevel gear 304. Through this transmission mechanism, the rotational movement of the rotating motor 302 can be efficiently and stably transmitted to the threaded rod 301, realizing the smooth driving of the moving seat 203, ensuring the reliability of the equipment operation, and providing a strong guarantee for accurate fire extinguishing.

[0028] In this embodiment, a rotating shaft 501 is rotatably installed on one inner wall of the box body 204. An incomplete gear 502 is fixedly sleeved on the rotating shaft 501. A driving seat 503 is fixedly installed on the top of the incomplete gear 502. A transmission gear 504 is fixedly installed on the rotating shaft 401, and the incomplete gear 502 meshes with the transmission gear 504. This structural design enables the rotating shaft 401 to drive the nozzle 105 to perform regular reciprocating rotation, effectively expanding the spraying range of the nozzle 105, being able to better cope with the spreading ignition points, and significantly improving the fire extinguishing efficiency.

[0029] In this embodiment, a driving motor 602 is installed on the other inner wall of the box body 204. A driving mechanism is provided between the driving motor 602 and the driving seat 503. The driving mechanism includes a connecting seat 603, a driving rod 604, and a driving hole 601. The connecting seat 603 is fixedly installed on the output shaft of the driving motor 602. A driving rod 604 is fixedly installed on one side of the connecting seat 603. The driving hole 601 is opened on the driving seat 503, and the driving rod is slidably connected to the driving hole 601. This driving mechanism can convert the rotational movement of the driving motor 602 into the reciprocating swing of the driving seat 503, and then drive the reciprocating rotation of the incomplete gear 502 and the nozzle 105. The structure is simple and the transmission is efficient, enhancing the practicability of the equipment.

[0030] In this embodiment, a fire source detector 106 is installed at the bottom of the box body 204. A controller 107 is fixedly installed on the top of the mounting frame 101, and the fire source detector 106, the rotating motor 302, the driving motor 602, and the solenoid valve 103 are all electrically connected to the controller 107. This connection method realizes the automatic control of the equipment. The fire source detector 106 can quickly sense the position of the fire source and feedback it to the controller 107. The controller 107 precisely regulates the coordinated operation of each component, greatly improving the fire extinguishing response speed and ensuring the efficiency and timeliness of the fire extinguishing operation.

[0031] Working principle of the utility model: When a fire breaks out inside the electrical cabinet, the rotation motor 302 can be started through the controller 107. The rotation motor 302 can drive the threaded rod 301 to rotate. The threaded rod 301 can drive the moving seat 203 and the box body 204 to move left and right. The box body 204 can drive the fire source detector 106 and the controller 107 to move left and right. The fire source detector 106 can detect the fire source, facilitating the movement of the nozzle 105 above the fire source. Through the controller 107, the solenoid valve 103 can be opened, enabling the dry powder fire extinguishing agent in the dry powder fire extinguishing agent tank 102 to be sprayed towards the fire source through the nozzle 105. At the same time, through the controller 107, the driving motor 602 can be driven to rotate. The driving motor 602 can drive the connecting seat 603 and the driving rod 604 to rotate. The driving rod 604 can drive the driving seat 503 to reciprocally rotate around the rotation axis 501 through the driving hole 601. The driving seat 503 can drive the incomplete gear 502 to reciprocally rotate around the rotation axis 501. The incomplete gear 502 can drive the transmission gear 504 and the rotating shaft 401 to reciprocally rotate. The rotating shaft 401 can drive the nozzle 105 to swing back and forth through the rotating seat 402, increasing the spraying range and achieving the purpose of extinguishing the spreading ignition points.

[0032] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly.
