Description

Technical Field

[0001] The invention relates to the technical field of fire protection for building external climbing frames, and in particular to a fire protection sprinkler device and method for building external climbing frames. Background Art

[0002] The building external climbing frame is also called the attached lifting scaffolding. It is a new type of scaffolding system developed. The building external climbing frame is composed of a variety of parts and structures such as a vertical main frame, a horizontal support truss, a frame structure, an attached support structure, an anti-tilt device, and an anti-fall device. The building external climbing frame has the characteristics of no height restriction, saving manpower, saving materials, and safety. According to its power source, it can be divided into several main categories such as hydraulic, electric, and pneumatic. The building external climbing frame is mainly used for external protection and working platforms during the main construction and exterior wall decoration stages of high-rise and super-high-rise buildings. It can climb up or down along the building, and has great application and promotion advantages in high-rise building construction. Since the building external climbing frame climbs or descends with the construction position of the building, the welding sparks sputtered at the construction site will cause the building external climbing frame to have a fire risk, especially when using wooden formwork construction technology and taking insulation measures during winter construction, it is easy to cause a fire. Therefore, it is necessary to install a fire sprinkler device on the building external climbing frame for fire monitoring and firefighting.

[0003] However, the size of the building's external climbing frame is determined according to the size of the building. Generally, the size of the building's external climbing frame is relatively large. Therefore, in order to ensure the fire-fighting effect at various positions of the building's external climbing frame, it is necessary to install fire monitoring components and sprinkler components at various positions of the building's external climbing frame, which greatly increases the cost; and the patent document with the published announcement number CN117504185A discloses a fire sprinkler device and method for a building's external climbing frame. This published patent document facilitates the water spray pipe to move left and right, so that the water spray pipe can be aimed at the fire source, so that the water spray pipe can spray the combustibles in the direction of the flame spread, thereby reducing the speed of the flame spread and reducing the disaster caused by the fire; however, in the above-mentioned published patent document, the sprinkler part can only move vertically along the building's external climbing frame. Since the building's external climbing frame is relatively large in lateral and overall dimensions, there is also the problem of needing to install fire monitoring components and sprinkler components at various positions of the building's external climbing frame, which costs a lot.

[0034] In this embodiment, the slide rails 2 are arranged on the upper and lower sides of the outer periphery of the external climbing frame 1. The servo motor 34 drives the roller 36 to rotate. The roller 36 moves along the inside of the track groove 21, so that the rectangular frame 31 moves along the slide rail 2. During the movement of the rectangular frame 31, the smoke alarm 37 and the infrared sensor 38 are used to monitor whether a fire occurs at various positions of the external climbing frame 1. There is no need to install fire monitoring components and sprinkler components 4 at various positions of the external climbing frame 1 to complete the functions of fire monitoring and fire fighting on the external climbing frame 1, which greatly reduces the cost. In addition, the smoke alarm 37 and the infrared sensor 38 are used for dual fire monitoring to prevent the smoke alarm 37 from misjudging welding or smoking smoke as fire smoke.

[0035] Furthermore, the servo motor 2 35 rotates and drives the threaded shaft 32 to rotate.

A fire sprinkler device for an external climbing frame of a building according to claim 2, characterized in that: A plurality of the smoke alarms (37) and infrared sensors (38) are provided, and the plurality of the smoke alarms (37) and infrared sensors (38) are equidistantly mounted on both sides of the rear portion of the rectangular frame (31).

7. A fire sprinkler device for an external climbing frame of a building according to claim 2, characterized in that: A sealing ring is provided between the connecting pipe (49) and the spray pipe (42).

8. A fire sprinkler device for an external climbing frame of a building according to claim 3, characterized in that: The top of the water tank (51) is connected to a water inlet pipe (52).

9. A fire sprinkler device for an external climbing frame of a building according to claim 3, characterized in that: A support plate (54) is fixedly connected to the bottom of the water tank (51), and the support plate (54) is fixedly mounted on the top front side of the rectangular frame (31).

10. A method for using the fire sprinkler device for an external climbing frame of a building as claimed in claims 2 to 9, characterized in that: The following steps are involved: S1: The servo motor 1 (34) rotates and drives the roller (36) to rotate. The roller (36) cooperates with the track groove (21), so that the roller (36) moves along the inside of the track groove (21), thereby driving the rectangular frame (31) to move along the slide rail (2). During the movement of the rectangular frame (31), the smoke alarm (37) and the infrared sensor (38) are used to monitor whether a fire occurs at various positions of the external climbing frame (1); S2: When the smoke alarm (37) and the infrared sensor (38) in the above S1 detect a fire situation, the servo motor 2 (35) rotates and drives the threaded shaft (32) to rotate, and the threaded shaft (32) drives the spray assembly (4) to move up and down along the rectangular frame (31). The spray assembly (4) reaches a suitable height, and the water pump (55) transports the water in the water tank (51) to the inside of the spray pipe (42), and finally sprays the water through the spray head (43) to extinguish the fire; S3: When the horizontal distance of the firefighting position in the above S2 is relatively far, the servo motor three (45) rotates and drives the lead screw (46) to rotate, the lead screw (46) drives the connecting piece one (47) to move along the slide groove (44), and the connecting piece one (47) drives the sprinkler head (43) to move to the vicinity of the fire through the sprinkler pipe (42) to spray and extinguish the fire; S4: When the fire range in the above S2 is large, the servo motor four (412) rotates and drives the gear one (413) to rotate, and the gear one (413) drives the sprinkler pipe (42) and the sprinkler head (43) to rotate through the gear two (414), thereby increasing the sprinkler fire fighting range.
