Description

Technical Field

[0001] The utility model belongs to the technical field of fire fighting and relates to a fire fighting and extinguishing spraying device. Background Art

[0002] The battery module mainly includes a shell and a battery pack installed inside the shell. In order to make full use of the space, the distance between the top of the battery pack and the top plate of the shell is usually only a few millimeters.

[0003] Most of the existing fire extinguishing spray devices are direct-spray type. For example, the energy storage battery pack fire nozzle disclosed in the Chinese invention patent application with application number publication number CN117205500A has a nozzle body directly mounted on the base, and the spraying position is completely determined by the mounting position. If this type of spray device is installed on the top of the shell, the coverage area is extremely small due to the insufficient spray distance, and the fire extinguishing effect is poor. If it is installed on the upper part of the side wall of the shell, the nozzle body itself has a large diameter, resulting in the spray position being actually lower than the top of the battery pack, and the agent can only be sprayed on the side wall of the battery pack, and the desired fire extinguishing effect cannot be obtained.

[0028] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments.

[0029] like Figures 1 to 3 A battery module elbow type fire extinguishing spray device comprises a supporting body 5 and a nozzle 1, and also comprises an elbow 2. One end of the elbow 2 is connected to the liquid outlet of the supporting body 5, and the other end is connected to the nozzle 1.

[0030] The support body 5 is mounted on the housing of the battery module through a reinforcing plate 8 and bolts 7. The bolts 7 pass through the flat spring pad, the reinforcing plate 8 and the side wall of the housing in sequence and are connected to the threaded holes of the support body 5. The reinforcing plate 8 can increase the clamping area.

[0031] Furthermore, a first sealing gasket 9 is provided between the reinforcing plate 8 and the supporting body 5 , and the first sealing gasket 9 is sleeved on the outer side of the bolt 7 .

[0032] The bent pipe 2 is preferably a copper pipe, which can be cut and bent according to actual needs during the processing stage.

[0033] The elbow 2 and the liquid outlet of the supporting body 5 can be directly connected (such as welding) or indirectly connected through other components. In this embodiment, one end of the elbow 2 is connected to the liquid outlet of the supporting body 5 through a pipe joint 4 and a ferrule joint 3. One end of the elbow 2 is inserted into one end of the pipe joint 4, and the other end of the pipe joint 4 is threadedly connected to the liquid outlet of the supporting body 5 and sealed with a sealant. The ferrule joint 3 sleeved on the outside of the elbow 2 is threadedly connected to one end of the pipe joint 4. After loosening the ferrule joint 3, the angle of the elbow 2 relative to the supporting body 5 can be adjusted. When tightening the ferrule joint 3, the ferrule joint 3 pushes the elbow 2 to be stuck in the chamfer of the pipe joint 4, so that the whole is deformed and fits to achieve a hard seal.

[0034] Furthermore, a sealing block 11 and a spring 10 are provided inside the liquid inlet of the support body 5. The outer end of the spring 10 contacts the sealing block, and the inner end contacts the pipe joint, and is used to push the sealing block 11 outward to achieve sealing of the liquid inlet.

[0035] Furthermore, a tapered hole is provided on the inner side of the liquid inlet, and a tapered surface matching the tapered hole is provided on the outer end of the sealing block 11, and a liquid inlet through hole is provided on the tapered surface, and the liquid inlet through hole is connected with the liquid outlet through the inner cavity of the supporting body 5. A second sealing gasket 12 is also installed on the tapered surface, and the second sealing gasket 12 is located on the outer side of the liquid inlet through hole. When the external medicine pressure is low, the tapered surface of the sealing block 11 and the tapered hole are in close contact with each other under the action of the spring 10 and squeeze the second sealing gasket 12, and the liquid inlet is in a sealed state at this time. When the external medicine pressure is high, the sealing block 11 is pushed open, and the medicine reaches the nozzle 1 through the liquid inlet through hole, the liquid outlet and the elbow 2.

[0036] Furthermore, the nozzle 1 is installed at the other end of the elbow 2 by threaded connection or welding. The end of the nozzle 1 has a straight-shaped opening, and the liquid sprayed is fan-shaped, and the spraying direction is parallel to the top surface of the battery pack.

[0037] Furthermore, a rotary quick-connect connector 6 is connected to the outer side of one end of the liquid inlet of the support body 5. A third sealing gasket 13 is provided between the support body 5 and the quick-connect connector 6.

[0038] The sealing gasket is made of hydrogenated nitrile rubber or other corrosion-resistant rubber.

[0039] During processing, the bent pipe 2 is processed according to the installation position of the support body 5 and the desired spraying position, while also considering the wiring harness inside the battery module. If necessary, the shape of the bent pipe 2 can be changed to avoid interference with the wiring harness.

[0040] During installation, bolts 7 are used to fix the support body 5 on the side wall. If the bolts 7 are blocked by the elbow 2, the ferrule joint 3 can be temporarily loosened, the elbow 2 is rotated, and the ferrule joint 3 is tightened after the installation is completed, and ensure that the nozzle 1 is in the desired position.

[0041] During operation, the agent pushes open the sealing block 11, passes through the supporting body 5, the pipe joint 4 and the elbow 2 to reach the nozzle 1, and then is sprayed out in a fan shape, and finally falls on the upper surface of the battery pack to complete the fire extinguishing operation.

[0042] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. The scope of the present invention is defined by the claims rather than the above description.
