Among them, the fire water monitor, as an efficient fire extinguishing tool, has been widely used, especially in places with high fire risk such as large buildings, warehouses, industrial plants, etc. The traditional fire water monitor system is mostly fixed, relying on manual control or simple automatic system for operation. However, with the development of automation and intelligent technology, the market demand for intelligent fire equipment is increasing, requiring the equipment not only to have strong fire extinguishing ability, but also to have flexible operation mode and higher concealment. For example, in places such as conference centers, tourist attractions, transportation hubs, etc., the exposure of equipment will affect the overall aesthetics of the place, and may even increase the risk of damage due to the exposed location of the equipment. Therefore, the development of a fire water monitor with automation, strong concealment and efficient response to fire has become a technical problem that needs to be solved in the field of fire protection.

[0003] The existing fire water monitor system mainly has several technical deficiencies. Most of the existing fire water monitor systems lack intelligent lifting design and cannot adjust the working state of the water monitor flexibly according to the site conditions, especially in complex environments for precise fire extinguishing. In addition, most of the existing equipment relies on manual or semi-automatic operation, with slow response speed, and may not be able to achieve timely fire source positioning and fire extinguishing operation at the critical moment of the initial stage of the fire. The present application introduces the design of electric push rod and telescopic sleeve assembly to overcome these deficiencies. SUMMARY

[0004] The purpose of this section is to outline some aspects of the embodiments of the present application and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract and title of the application to avoid obscuring the purpose of this section, the abstract and the title of the application, and such simplifications or omissions cannot be used to limit the scope of the present application.

[0024] Please refer to Figs. 1 to 3 The present application provides an automatic fire water cannon electric lifting device, which comprises a front fixed plate 10, a rear fixed plate 11, an electric push rod 12 and a telescopic sleeve assembly. The design of the whole device aims to improve the flexibility and automation of the fire water cannon. The electric push rod 12 is fixed between the front fixed plate 10 and the rear fixed plate 11, and is responsible for pushing the lifting operation of the fire water cannon. The push rod can quickly raise the water cannon when the fire alarm is triggered, execute the automatic fire extinguishing function, and hide the water cannon in the shelter in standby state, keeping the environment beautiful. The telescopic sleeve assembly is arranged between the front and rear fixed plates 11, further ensuring the movement stability and reliability of the push rod.

[0025] In the preferred technical solution, the side of the telescopic sleeve assembly close to the front fixed plate 10 is provided with a guide plate 13, and the electric push rod 12 passes through the guide plate 13 and is connected with the front fixed plate 10. This design helps the accurate guidance of the push rod, avoids the phenomenon of deviation or uneven stress in the lifting process, thereby improving the operation stability of the device. The setting of the guide plate 13 not only improves the compactness of the structure, but also reduces the friction resistance of the device, making the movement of the push rod more smooth.

[0026] Further optimization, telescopic sleeve assembly includes cylinder sleeve 14 and hollow piston rod 15. The bottom of the cylinder sleeve 14 is fixedly connected to the rear fixed plate 11, and the top is connected to the front fixed plate 10 through the guide plate 13. The hollow piston rod 15 is slidably connected with the cylinder sleeve 14, so that the push rod can keep smooth sliding operation during lifting. The top of the hollow piston rod 15 penetrates through the guide plate 13 and is fixedly connected to the front fixed plate 10, so as to ensure the stability of the overall structure of the device.

[0027] In order to further improve the sliding effect of the push rod, the hollow piston rod 15 is slidably connected with the top of the cylinder sleeve 14 through the guide sleeve 16, and the guide sleeve 16 is fixed on the top of the cylinder sleeve 14 through the gland 26. The guide plate 13 is connected with the top of the cylinder sleeve 14 through the gland 26, which ensures the structure of the whole device is compact and prevents the push rod from loosening or deviating during lifting. In addition, the top of the hollow piston rod 15 is fixedly connected to the custom flange 24, which further enhances the stability and carrying capacity of the device.

[0028] The device also has a limit switch 18 which is fixedly connected to the gland 26 through a limit switch bracket 17. The limit switch 18 can accurately detect the position of the hollow piston rod 15, ensuring that it automatically stops at the predetermined position, thereby preventing damage to the device caused by excessive lifting and greatly improving the safety of the device.

[0029] In addition, the bottom of the cylinder sleeve 14 is fixedly connected to the high-necked grooved flange 20 through the grooved rigid clamp 19, which increases the connection strength of the cylinder sleeve 14 and its accessories. The bottom of the hollow piston rod 15 is slidably connected with the cylinder sleeve 14 through the piston 21, and the piston 21 is fixed inside the cylinder sleeve 14 through the precision R-type locking nut 22. The top of the cylinder sleeve 14 is also provided with a breather cap 23, which can maintain internal air pressure balance during lifting and prevent device failure caused by unbalanced air pressure.

[0030] In order to further ensure the sealing performance of the device, O-rings 25 are provided between the piston 21 and the cylinder sleeve 14, between the piston 21 and the hollow piston rod 15, between the gland 26 and the cylinder sleeve 14, and between the guide sleeve 16 and the hollow piston rod 15. These sealing rings can effectively prevent the leakage of liquid or gas, ensuring that the device can operate stably for a long time in a high-pressure environment. Through these optimization designs, the automatic fire-fighting water cannon electric lifting device of the present application not only has a compact and reliable structure, but also has high operation flexibility and safety, and is suitable for various complex fire-fighting scenes. The embodiments are only used to illustrate the technical solutions of the present application and not to limit.
