[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1-Figure 2 The utility model provides an embodiment: a new energy vehicle fire extinguishing water gun, comprising a water inlet pipe 1, a branch pipe 4 fixedly connected to the rear end of the water inlet pipe 1, a gun head 5 fixedly connected to the upper end of the branch pipe 4, a dust shield 2 fixedly connected to the upper end of the gun head 5, and an extension device 3 provided at the end of the branch pipe 4 away from the water inlet pipe 1;

[0032] The dust shielding device 2 includes a baffle 203, the inner side of which is fixedly connected to a fixed shaft 205, the outer arc surface of which is rotatably connected to an outer shaft 204, the outer arc surface of which is fixedly connected to a sealing block 201, and the lower part of the inner arc surface of the baffle 203 is fixedly connected to a limiting block 202.

[0033] The outer arc surface of the shielding plate 203 is fixedly connected to the gun head 5, and a rectangular groove is provided at the center of the inner surface of the shielding plate 203, so that the sealing block 201 can be located inside it. The inner side of the shielding plate 203 is provided with an arc-shaped groove, so that the outer shaft 204 can be closely contacted with it. The outer surface of the fixed shaft 205 is elastically connected to the outer shaft 204 by a spiral spring. Therefore, when not affected by external forces, the spiral spring can always drive the sealing block 201 to contact the limit block 202. A through hole is provided at the center of the inner surface of the outer shaft 204, so that the fixed shaft 205 can be located inside it. The outer surface of the outer shaft 204 is in close contact with the shielding plate 203, and the end of the sealing block 201 away from the outer shaft 204 is set to an arc surface, so that it will not interfere with the movement between the gun head 5 during rotation. The outer surface of the limit block 202 is fixedly connected to the gun head 5, and the upper surface of the limit block 202 is in contact with the sealing block 201.

[0034] Reference Figure 1 、 Figure 3 The extension device 3 includes a movable tube 303, the outer arc surface of the movable tube 303 is slidably connected to the connecting tube 301, the outer arc surface of the movable tube 303 is fixedly connected to the ring block 305, the outer arc surface of the ring block 305 is hinged with a clamping rod 302, and the end of the clamping rod 302 away from the ring block 305 is fixedly connected to the clamping block 304.

[0035] The movable tube 303 is fixedly connected to the branch tube 4 at one end away from the ring block 305. A plurality of rectangular slots are provided on the outer surface of the movable tube 303, so that the insertion of the block 304 can be accommodated, and the exposed length of the movable tube 303 can be limited by the clamping connection between the two. An annular groove is provided on the inner surface of the connecting tube 301. The diameter of the movable tube 303 is smaller than the diameter of the connecting tube 301. The outer surface of the ring block 305 is elastically connected to the clamping rod 302 by a spiral spring, so that the block 304 can be kept embedded in the slot at all times without being affected by external forces. The lower end size of the block 304 is smaller than the size of the slot on the outer surface of the connecting tube 301.

[0036] Working principle: When this device is not in use, the vortex spring will use its own elastic force to drive the sealing block 201 to move toward the limit block 202 and maintain the fit between the two. At the same time, due to the close fit between the outer shaft 204 and the baffle 203, dust can only fall on the outer surface of the sealing block 201 and the baffle 203. When this device is in use, since the water pressure inside the water gun is greater than the elastic force of the vortex spring, the sealing block 201 can be pushed to rotate. At this time, the gun head 5 will be released from the sealing state, and the dust outside the sealing block 201 cannot affect the normal water output at the gun head 5.

[0037] In addition, when facing different models of new energy vehicles, due to the different installation positions of the batteries at the bottom, when extinguishing a fire, it is necessary to pull the card rod 302 outward. At this time, the card block 304 will be away from the card groove on the outer arc surface of the connecting tube 301. At this time, the connecting tube 301 can be pushed to change the extension distance of the movable tube 303, and thereby adjust the distance between the front and rear groups of branch pipes 4. When the adjustment is completed, the card rod 302 needs to be loosened. At this time, due to the vortex spring force between the ring block 305 and the card rod 302, the card rod 302 can be driven to rotate, and the card block 304 is embedded in the card groove on the outer arc surface of the connecting tube 301 to complete the limiting of the device.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
