Description

Technical Field

[0001] This utility model relates to a power fire protection device. Background Technology

[0002] With the transformation of the global energy structure and the in-depth implementation of sustainable development strategies, wind power, as an important component of clean energy, has seen continuous improvement in its installed capacity and power generation efficiency. However, as a crucial link in the transmission of electricity from wind turbine generators, the fire safety of the power facilities at wind farm substations is of paramount importance. Existing fire protection devices for wind power substations have significant shortcomings in operation. When a fire occurs, these devices often can only passively wait for the fire to spread to the substation before extinguishing it, lacking the ability to predict and respond promptly. This leads to the escalation of the accident and seriously affects the practicality and safety of the equipment.

[0003] The main cause of the fire at the substation was cable overload, which led to the cable igniting. Because the cable was located at a high position, it was difficult for the ground-based fire extinguishing equipment to accurately spray the ignition point of the cable, resulting in the fire becoming uncontrollable.

[0004] Based on the above problems, we designed a power fire protection device that can be used for mobile fire extinguishing and can target burning cables with spray. Utility Model Content

[0025] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0026] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0027] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Furthermore, in the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "socket," "connect," "through," and "plug-in" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0030] See Figure 1 , Figure 2 and Figure 5 As shown, the device includes a storage tank 1 for storing carbon dioxide, a valve 11 installed on the top of the storage tank 1, a pressure gauge 12 for monitoring the internal pressure of the storage tank 1 installed at one end of the valve 11, and a hose 13 for delivering carbon dioxide installed at the other end. It also includes a trolley structure 2, a height adjustment device 3 that works with the trolley structure 2, and an injection device 4 carried by the height adjustment device 3. The storage tank 1 is carried by the trolley structure 2, and the injection device 4 is connected to the hose 13.

[0031] In the above technical solution, carbon dioxide is stored in storage tank 1. Under normal pressure, liquid carbon dioxide will immediately vaporize, and generally 1 kg of liquid carbon dioxide can produce about 0.5 cubic meters of gas. Therefore, during fire extinguishing, carbon dioxide gas can displace air and surround the surface of the burning object or be distributed in a relatively confined space, reducing the oxygen concentration around the combustible material or in the protected space, thus suffocating the fire. In addition, when carbon dioxide is sprayed from the storage container, it will rapidly vaporize from liquid to gas, absorbing some heat from the surroundings and playing a cooling role.

[0032] The height adjustment device 3 is used to press the spray device 4 down to be below the ignited cable. Then, by releasing the height adjustment device 3, the spray device 4 is raised, at which point the ignited cable is inserted into the spray device 4.

[0033] By opening valve 11, carbon dioxide is directed along the injection device 4 to the ignition point of the cable. Example

[0034] See Figure 1 and Figure 2As shown, the trolley structure 2 includes a push plate 21 and a vertical plate 22 welded to the side of the push plate 21. A container 23 for placing the storage tank 1 is welded to the top of the push plate 21. Rollers 24 are installed on the outside of the vertical plate 22. Casters 25 are installed at the bottom of the push plate 21 away from the vertical plate 22. A support plate 26 is welded to the outer side of the vertical plate 22. The height adjustment device 3 is slidably installed through the support plate 26. A vertical groove 221 runs through the surface of the vertical plate 22, and the hose 13 passes through the vertical groove 221.

[0035] The combination of rollers 24 and casters 25 provides triangular support at the bottom of the push plate 21.

[0036] The position of the push plate 21 can be moved to facilitate displacement along the burning cable and complete mobile fire extinguishing. Example

[0037] See Figure 3 As shown, the height adjustment device 3 includes a movable plate 31, with two guide rods 32 fixedly installed at the bottom of the movable plate 31. The guide rods 32 pass downward through the support plate 26, and the bottom of the guide rods 32 is threaded with a limit cap 33, which limits the upward displacement of the guide rods 32. A spring 34 is fitted on the guide rods 32. A connecting pipe 35 is welded through the movable plate 31, and an insulating liner 36 is interference-fitted into the inner wall of the connecting pipe 35. The spraying device 4 passes through the insulating liner 36, and a locking bolt 37 for pressing the insulating liner 36 is screwed into the outer wall of the connecting pipe 35. Insulating handles 38 are installed at both ends of the movable plate 31.

[0038] In the above technical solution, the movable plate 31 is pressed down by operating the insulating handle 38, so that the upper end of the spraying device 4 is lower than the height of the ignited cable. Then, the spraying device 4 returns to its original height by the rebound action of the spring 34 through the insulating handle 38.

[0039] The device is pushed forward by operating the insulated handle 38.

[0040] The function of the insulating liner 36 is to improve insulation. Example

[0041] See Figure 2 As shown, a sleeve 261 is provided on the top of the support plate 26, the guide rod 32 passes through the sleeve 261, the lower end of the spring 34 acts on the top of the sleeve 261, and a first locking bolt 262 for fixing the guide rod 32 is screwed into the outside of the sleeve 261.

[0042] This technical solution can further extend the height of the guide rod 32 and lock it in place using the first locking bolt 262. Example

[0043] See Figure 2 , Figure 3 and Figure 4 As shown, the spraying device 4 includes an arc-shaped plate 41 with a cavity inside. Multiple nozzles 42 for spraying carbon dioxide gas are arranged in a ring on the inner arc surface of the arc-shaped plate 41. An opening 43 is provided at the top of the arc-shaped plate 41, and a connecting end is provided at the bottom of the arc-shaped plate 41. A rigid tube 44 is installed through the connecting end. The lower end of the rigid tube 44 is connected to the flexible tube 13, and the rigid tube 44 passes through the insulating liner 36.

[0044] In the above technical solution, the design of the arc-shaped plate 41 allows for concentrated carbon dioxide spraying around the fire location of the cable, increasing the effective density and enhancing the fire extinguishing effect. Example

[0045] See Figure 3 As shown, fireproof plates 441 are installed at both ends of the arc-shaped plate 41. The top of the fireproof plate 441 is provided with a U-shaped groove 442 for inserting cables, and the U-shaped groove 442 corresponds to the opening 43.

[0046] Fireproof board 441 can form a certain obstruction on both sides of curved board 41, so that the carbon dioxide spray is further concentrated and the fire extinguishing effect is increased. Example

[0047] See Figure 3 As shown, an insulating rubber plate 443 is fixed to the wall of the U-shaped groove 442, and both ends of the insulating rubber plate 443 extend upward to the outer wall of the arc-shaped plate 41.

[0048] In this technical solution, the insulating rubber plate 441 can make soft contact with the cable, and secondly, it plays an insulating role, especially for extinguishing fires when the cable is energized.

[0049] See Figure 2 As shown, a fireproof umbrella 444 is fixedly installed on the rigid tube 44.
