TECHNICAL FIELD
[0001] The utility model relates to hoist technology field, concretely relates to a kind of automatic fire water cannon electric hoist. BACKGROUND
[0002] Infrared positioning technology plays a crucial role in automatic fire extinguishing systems, especially in industrial environments with potential explosion risks such as petrochemical, power, and mining industries. Traditional infrared flame detectors rely on capturing the unique infrared radiation emitted by flames, using various sensing technologies to accurately locate the source of the fire. These positioning systems are mainly divided into infrared and image type detectors. Infrared locators are popular due to their lower cost and simple structure, especially in scenarios where technical cost is a concern. However, image type detectors, despite their higher accuracy and detection capabilities, are limited in their use due to their complexity and high cost. To address specific needs in the industrial sector, many fire extinguishing systems still rely on infrared positioning technology to achieve rapid and efficient fire source location.
[0003] While traditional infrared positioning systems have basic functionality, they face a series of challenges in high-risk environments. First, infrared locators are susceptible to interference, especially their narrow slit design which can lead to significant errors in accurate positioning. Typically, these systems use pyroelectric infrared sensors that capture flame signals through narrow vertical or horizontal slits, however this design increases the risk of positioning errors. Additionally, designing an infrared positioning system to meet explosion-proof standards (such as C-class explosion-proof requirements) is more complex. Such environments require the use of specialized explosion-proof glass and robust sensor housings to ensure the safety and reliability of the positioning device in hazardous environments.
[0004] The explosion-proof infrared positioning device of the present invention improves the stability and accuracy of the system in hazardous environments by using explosion-proof infrared glass, locking pressure rings, and specialized infrared sensor layout, solving the problem of large errors and difficulty in achieving explosion-proof performance of traditional infrared locators in high-risk scenarios.

In addition, the three-dimensional spatial dimensions of length, width and depth should be included in actual production.
[0022] Please refer to Figs. 1 to 3 The explosion-proof infrared positioning device includes a positioner front cover 10, an explosion-proof infrared glass 11, a locking ring 13, an explosion-proof infrared gun positioner plate 17, a high-definition camera 19, a positioner shell 22 and a positioner rear cover 23. The device realizes accurate positioning of the flame in a dangerous environment through a unique design. The explosion-proof infrared glass 11 is fixed in the positioner front cover 10 through the locking ring 13, ensuring the firmness and sealing of the glass, which can effectively prevent the penetration of explosive gas. The positioner rear cover 23 is connected to the front cover through the positioner shell 22, forming a complete explosion-proof structure. The high-definition camera 19 is installed in the positioner shell 22 through the explosion-proof infrared gun positioner plate 17, responsible for real-time monitoring and assisting the flame positioning function. The structure design is simple, and has high strength explosion-proof function.
[0023] In the preferred technical solution, the locking ring 13 is in close contact with the explosion-proof infrared glass 11 through the fluorine gasket 12, ensuring the sealing performance of the device in high-temperature and high-pressure environments. The fluorine gasket 12 has excellent corrosion resistance and temperature resistance, effectively improving the adaptability of the device in harsh environments. In addition, the explosion-proof infrared cannon locator plate 17 is fixed above the explosion-proof infrared glass 11 through the infrared positioning plastic shell 14, further enhancing the stability of the device. The locator plate not only integrates the flame positioning function, but also carries two horizontal and vertical pyroelectric infrared sensors, realizing multi-dimensional fire source detection. Through the cooperation of the two sensors, the device can quickly and accurately capture the position of the fire source and effectively reduce errors.
[0024] To further improve the stability and durability of the structure, the high-definition camera 19 is connected to the explosion-proof infrared cannon locator plate 17 through four double-pass knurled copper columns 18, forming a stable mounting structure. This copper column design not only enhances the anti-shock performance of the camera, but also ensures the long-term service life of the camera in complex environments. The close connection between the copper columns ensures the stability of signal transmission, preventing signal loss or failure due to mechanical vibration or external force.
[0025] In addition, the explosion-proof infrared cannon locator plate 17 is fixed in the locator shell 22 through the hexagonal single-head copper column 21. This structure design is simple and firm, and at the same time ensures the stability between the locator plate and the shell. The hexagonal single-head copper column 21 not only facilitates operation during installation, but also effectively improves the reliability and durability of the system, especially in environments with high explosion-proof requirements, this design is particularly important.
[0026] To ensure the sealing of the overall structure, the two ends of the locator shell 22 are tightly connected to the locator front cover 10 and the rear cover through O-rings 20. The O-rings 20 have very high sealing performance, ensuring that the entire device can still maintain good waterproof performance in extreme environments. In addition, the locator shell 22 is also designed with an explosion-proof plug 24, further enhancing the protection level of the device and ensuring that it can maintain stable performance after long-term use.
