Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted fire extinguishing, and more specifically, particularly relates to a vehicle-mounted automatic fire extinguishing sprinkler. Background Art

[0002] The car fire extinguisher is specially used for extinguishing fire in cars. When extinguishing fire, pull out the safety pin, aim the nozzle at the fire source, and press the handle to extinguish the fire. However, the nozzle of the car fire extinguisher is usually fixed and cannot be rotated. The spray range of the nozzle can only be expanded by moving the position of the car fire extinguisher.

[0003] The patent with announcement number CN214971450U discloses a fire extinguisher with an automatic rotating nozzle. When a fire occurs, the rotating rod of the fire extinguisher is rotated to drive the butterfly plate to rotate through the connecting rod. When the butterfly plate is rotated to a certain position, the bottle mouth of the pressurized bottle and the air outlet are in a communicating state, and the pressurized gas is discharged into the inner cavity of the fire extinguisher through the air outlet. The fire extinguishing material in the fire extinguisher enters the nozzle through the discharge pipe under pressure and is sprayed out through the nozzle. The soft plug at the nozzle is impacted open, and the spray force drives the nozzle to rotate relative to the cover plate, so that the fire extinguishing material is evenly sprayed on the fire scene. The above-mentioned fire extinguisher utilizes the spray force of the fire extinguishing material to drive the nozzle to rotate, but the fire extinguisher needs to be modified from the conventional fire extinguisher, and a shell is added to the outside of the fire extinguisher. After the fire extinguishing material in the fire extinguisher is sprayed out, it first fills the shell and then can enter the nozzle along the discharge pipe for rotation and spraying. Not only is it time-consuming to install the shell consumables outside the fire extinguisher, but the material in the fire extinguisher can only be sprayed along the nozzle after filling the shell, which will also cause a waste of fire extinguishing materials. In addition, the added shell takes up a large space and is not convenient to place on the car. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-Figure 3 As shown, this embodiment provides a vehicle-mounted automatic fire extinguishing sprinkler, including a connecting platform 1, a gear assembly 2 and a power assembly 3. The connecting platform 1 is a plate-shaped structure, which serves as a supporting structure for the sprinkler as a whole. The gear assembly 2 is arranged on the connecting plate 1, which is used to drive the sprinkler assembly 4 to rotate; the power assembly 3 is arranged below the connecting platform 1, which is used to drive the gear assembly 2 to rotate.

[0028] Specifically, the power assembly 3 adopts a motor, and a motor sleeve 31 is fixedly connected below the connecting platform 1 , and the motor is fixedly installed in the motor sleeve 31 .

[0029] The gear assembly 2 includes a driving wheel 21 and a driven wheel 22 meshing with each other. The driving wheel 21 is connected to the output shaft of the motor; the driven wheel 22 is sleeved on the nozzle assembly 4 and is located above the connecting platform 1.

[0030] The nozzle assembly 4 is connected to the nozzle of the fire extinguishing material through a rotating joint 5. Specifically, the nozzle assembly 4 includes a main pipe 41 and a plurality of nozzles 42 located at the upper end of the main pipe 41. The upper end of the main pipe is sealed, and the side wall of the upper end is connected to a plurality of nozzles. The main pipe 41 is connected to the nozzle of the fire extinguishing material through a rotating joint 5, and the driven wheel 22 is fixedly sleeved on the outer wall of the main pipe 41. A plurality of nozzles 42 are connected to the outer wall of the upper end of the main pipe 41. In this embodiment, three nozzles 42 are evenly arranged, and each nozzle 42 is connected to the main pipe 41 respectively. The outlet 43 of the nozzle 41 is vertically upward, that is, the direction of the outlet 43 is perpendicular to the connecting platform. When the fire extinguishing material is dispersed to each nozzle 42 through the main pipe 41, it is sprayed outward along the outlet 42 of the nozzle. Since the rotation of the motor drives the driving wheel 21 to rotate, it can drive the driven wheel 22 to rotate, and at the same time, it can drive the plurality of nozzles to rotate. During the rotation of the nozzle, since the ejected fire extinguishing material carries a certain pressure, the fire extinguishing material rotates after being ejected, thereby expanding the ejection range of the fire extinguishing material.

[0031] In practical applications, the nozzle assembly can be provided with two nozzles, or can be provided with three or more nozzles.

[0032] The vehicle-mounted automatic fire extinguishing sprinkler can be fixed to the engine compartment of the vehicle or other preset positions by means of bolts or buckles.

[0033] The vehicle-mounted automatic fire extinguishing sprinkler provided in this embodiment can be set in the engine compartment or other locations of the vehicle. When in use, the main tube 41 in the sprinkler assembly 4 is connected to the nozzle of the fire extinguisher through the rotating joint 5, and the motor is turned on to drive the driving wheel 21 to rotate, so that the driven wheel 22 rotates accordingly, and then drives the main tube 41 fixed to the driven wheel to rotate. At this time, the multiple nozzles 42 at the end of the main tube 41 rotate, so that the fire extinguishing material can be rotated and sprayed, thereby increasing the spraying range of the fire extinguishing material.

[0034] The vehicle-mounted automatic fire extinguishing sprinkler provided in this embodiment has a simple structure, is easy to manufacture, occupies a small space, and can be installed at a suitable location in the car. When in use, it is connected to the nozzle of a fire extinguisher or the nozzle of other fire extinguishing equipment. After the fire extinguishing material is sprayed out from the fire extinguisher or other fire extinguishing equipment, it is directly transported to the main tube 41 of the sprinkler assembly 4 through its own nozzle, and then sprayed through the nozzle. There will be no waste of fire extinguishing material in the middle, and the fire extinguishing operation can be ensured to be carried out smoothly.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
