Description

Technical Field

[0001] This application relates to the technical field of fire-fighting devices, and more particularly, to a fire extinguishing system. Background Art

[0002] With the acceleration of the urbanization process, the number of underground spaces such as subways, tunnels, and underground shopping malls is increasing day by day, and the fire risk thereof is also increasing. In particular, the risk of spontaneous combustion of high-power charging devices such as new energy vehicles and electric vehicles increases the probability of fire occurrence. Due to the particularity of the underground space environment, once a fire occurs, the rescue difficulty is extremely high, and traditional fire-fighting equipment often fails to meet the rescue requirements. Therefore, the research and development of fire emergency rescue equipment suitable for underground spaces is of great significance for improving rescue efficiency and ensuring the safety of people's lives and property.

[0003] In the current rescue methods, if the traditional fire-fighting equipment is used for rescue, the fire-fighting equipment needs to be operated by professional personnel. During the process from the occurrence of the fire to the arrival of the personnel for handling, a certain waiting time is required. During this period, the fire situation is often unrestricted, and it is very likely that the fire will spread and cause greater losses.

[0004] In addition, some inspection-type fire-fighting devices have also been proposed in the prior art. By setting up inspection robots and fire-fighting pipelines, among which, the inspection robots can be used to locate the fire point, and a docking mechanism is provided between the inspection robots and the fire-fighting pipelines, so that the water in the fire-fighting pipelines can be output to perform fire suppression operations.

[0005] However, in this way, since the areas where fires may occur cannot be known in advance, especially for large underground spaces, this makes the layout of the fire-fighting pipelines need to be widely covered, resulting in increased application costs; moreover, the fire point and the docking point between the inspection robot and the fire-fighting pipeline are not necessarily in a corresponding state, so the fire suppression effect is very likely to fail to meet the preset requirements, and the overall flexibility in actual application is relatively low.

[0104] It should be noted that: Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application pertains. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. Similar reference numerals and letters denote similar items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. At the same time, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0105] As Figures 1 to 13 shown, in the solution of this embodiment, a fire extinguishing system is provided, including:

[0106] Track 1, hung in the controlled area;

[0107] Inspection device 2, movably arranged on the track 1. The inspection device 2 includes an identification part 21 and a first matching part 22. The identification part 21 is used for fire identification of the controlled area.

[0108] A plurality of fire extinguishing devices 3, movably arranged on the track 1 and independent of the inspection device 2. The plurality of fire extinguishing devices 3 are arranged at intervals along the length direction of the track 1. The fire extinguishing device 3 includes a delivery part 31 for controlling the output of fire extinguishing appliances and a second matching part 32. The first matching part 22 and the second matching part 32 can move to form a connection relationship so that synchronous movement is formed between the inspection device 2 and one of the fire extinguishing devices 3.

[0109] In some embodiments, the controlled area can be areas such as warehouses, shopping malls, parking lots, etc. At this time, the track 1 is hung above the goods storage area in the warehouse, or above the commodity storage area in the shopping mall, or above the parking spaces in the parking lot, and full coverage of the target areas (such as goods storage areas, commodity storage areas, parking spaces, etc.) in the controlled area is achieved.

[0110] In some embodiments, the controlled area can be areas such as tunnels, underground lines, etc. At this time, the track 1 is hung along the line in the controlled area.

[0111] In some embodiments, the identification part 21 can be set in application forms such as video recognition cameras, temperature sensors, smoke sensors, heat detectors, etc. By setting the identification part 21 on the inspection device 2, when the inspection device 2 conducts mobile inspections on the track 1, it is convenient to identify fires.

[0112] In some embodiments, the fire extinguishing appliance may include application forms such as liquid, powder, and solid; for example, when it is liquid, a water tank may be provided on the fire extinguishing device 3, and liquid water may be output to the fire point through the delivery part 31 to suppress the fire; when it is powder, powder may be delivered or sprayed to the fire point through the delivery part 31 to suppress the fire; when it is solid, the application form of a fire extinguishing bomb 4 may be adopted.

[0113] In this embodiment, the application form of the fire extinguishing bomb 4 is mainly used for illustrative purposes.

[0114] In some embodiments, the synchronous movement formed between the inspection device 2 and the fire extinguishing device 3 can be understood as the movement after the inspection device 2 and the fire extinguishing device 3 are connected and form an integral body, and it is not intended to limit the relative position relationship between the inspection device 2 and the fire extinguishing device 3. That is, when moving as a whole, the inspection device 2 and the fire extinguishing device 3 can be arranged to form a side-by-side form on the left and right, or can be arranged to form a front-to-back connected form.

[0115] By setting the track 1 within the controlled area, it is not only convenient to form coverage of the target area and reduce control blind spots, but also convenient to realize the rail operation of the inspection device 2 and the fire extinguishing device 3 within the controlled area.

[0116] By providing the inspection device 2 and making the operations between the inspection device 2 and the fire extinguishing device 3 independent of each other, the inspection device 2 can be used to monitor the fire situation within the controlled area, so that the fire can be discovered faster when a fire occurs, and the fire discovery response is more rapid; moreover, the inspection process can be carried out only through the inspection device 2, which is convenient for reducing the operation energy consumption of the system and has higher application flexibility.

[0117] By providing the first matching part 22 and the second matching part 32 and arranging a number of the fire extinguishing devices 3 at intervals along the length direction of the track 1, when the inspection device 2 discovers a fire, it can form synchronous movement with the nearest fire extinguishing device 3, so as to facilitate the movement of the fire extinguishing device 3 to the vicinity of the fire point and perform the operation of launching the fire extinguishing bomb 4, thereby suppressing the fire and realizing a rapid response from fire discovery to fire suppression.

[0118] As an application example, as Figure 6 、 Figure 10 shown, the delivery part 31 includes a swingably arranged hook 311, and the hook 311 is used for hanging the fire extinguishing bomb 4.

[0119] A limiting plate 312 is provided on the swinging path of the hook 311.

[0120] In some embodiments, it can be understood that during application, at least one of the fire extinguishing bombs 4 is mounted on the throwing part 31.

[0121] In some embodiments, the hook 311 is in a "J" shape and is swingably arranged on the fire extinguishing device 3.

[0122] In some embodiments, a lug 41 is provided on the fire extinguishing bomb 4, and the fire extinguishing bomb 4 is mounted on the hook 311 through the lug 41; during installation and application, the limiting plate 312 is arranged beside the lug 41, and when the hook 311 swings, the lug 41 will be blocked by the limiting plate 312 and disengaged from the hook.

[0123] By providing the hook 311, it is convenient to achieve the temporary mounting of the fire extinguishing bomb 4; and by setting the hook 311 in a swingable application form, the hook 311 can, under the action of an external driving force, cooperate with the limiting plate 312 to achieve the throwing operation of the fire extinguishing bomb 4.

[0124] As an application example, a snap connection is provided between the first engaging portion 22 and the second engaging portion 32. By setting a snap connection between the first engaging portion 22 and the second engaging portion 32, it is convenient to achieve the quick connection between the inspection device 2 and the fire extinguishing device 3, and thus achieve synchronous running on the track.

[0125] In some embodiments, as Figure 3 shown, the first engaging portion 22 includes a first telescopic rod 221, the first telescopic rod 221 is arranged on the inspection device 2, and the movable end of the first telescopic rod 221 is arranged towards the fire extinguishing device 3; the second engaging portion 32 includes a slot 321, the slot 321 is arranged on the fire extinguishing device 3, and a cooperation is formed between the slot 321 and the first telescopic rod 221, so that the first telescopic rod 221 can move to be inserted and connected with the slot 321.

[0126] In some embodiments, the telescopic direction of the first telescopic rod 221 is perpendicular to the length direction of the track 1.

[0127] When the inspection device 2 detects a fire, the inspection device 2 can move to the side of the nearest fire extinguishing device 3, and then by controlling the extension of the first telescopic rod 221, the first telescopic rod 221 can be extended into the slot 321 provided therein. At this time, a temporary connection between the inspection device 2 and the fire extinguishing device 3 can be achieved. In the connected state, the movement formed by the single - side drive of the inspection device 2 or the fire extinguishing device 3 will cause the whole formed after the connection of the inspection device 2 and the fire extinguishing device 3 to move. By controlling the contraction of the first telescopic rod 221, the first telescopic rod 221 can be made to leave the slot 321. At this time, the separation between the inspection device 2 and the fire extinguishing device 3 can be achieved, and the inspection device 2 can return to the normal independent inspection state.

[0128] As one of the application examples, as Figure 3 、 Figure 6 shown, a first rod section 2211 and a second rod section 2212 can be provided at the movable end of the first telescopic rod 221;

[0129] The first rod section 2211 can move with the first telescopic rod 221 to be inserted and connected to the slot 321;

[0130] The second rod section 2212 can move with the first telescopic rod 221 to abut against the hook 311.

[0131] In some embodiments, the telescopic stroke of the first telescopic rod 221 can be designed. For example, the stroke of the first telescopic rod 221 is set to include two segments. When the first telescopic rod 221 completes the first - stage extension stroke, the first rod section 2211 moves to form an insertion connection with the slot 321, and the second rod section 2212 and the hook 311 are in an independent state. At this time, the movement of the inspection device 2 can drive the fire extinguishing device 3 to move. Therefore, a power system can be provided only at the inspection device 2 end. When the inspection device 2 and the fire extinguishing device 3 move to the fire point, the first telescopic rod 221 continues to complete the second - stage extension stroke, so that the second rod section 2212 moves to abut against the hook 311, thereby driving the hook 311 to swing, and further realizing the delivery of the fire extinguishing bomb 4.

[0132] In some embodiments, as Figure 3 、 Figure 6 shown, the first rod section 2211 and the second rod section 2212 are integrally provided and are in an "L" shape.

[0133] By setting the movable end of the first telescopic rod 221 to an application form including a first rod section 2211 and a second rod section 2212, when the first telescopic rod 221 performs telescopic movement, it can not only satisfy the plug-in connection between the first rod section 2211 and the slot 321 to achieve the synchronous operation between the inspection device 2 and the fire extinguishing device 3, but also satisfy the abutting contact between the second rod section 2212 and the hook 311, thereby facilitating the control of the delivery of the fire extinguishing bomb 4, with a clever design.
