Description

Technical Field

[0001] The utility model specifically relates to the technical field of cooling the temperature of fire-fighting water guns, in particular to a fire-fighting water gun with a cooling function. Background Art

[0002] A fire hose is an important device used to spray water during fire extinguishing. The gun body is the main part of the fire hose and is usually made of metal (such as aluminum alloy, brass, etc.). It contains a water inlet, a water outlet, and an internal flow channel. The water inlet is used to connect the fire hose to introduce water into the hose. The water outlet is where the water is sprayed out.

[0003] At present, when traditional fire hoses are spraying, the water pressure of the nozzles is effectively adjusted manually to achieve different spraying pressures for different fires, or to achieve switching between multiple spraying pressures. However, in larger fires, firefighters cannot get close to the fire to effectively spray fire water. In this case, it is necessary to use drones or ladders to transport the fire hoses to a position close to the fire to achieve effective spraying and extinguishing of the fire. However, when extinguishing the fire, the spraying pressure of the nozzles needs to be automatically switched through the components inside the remote control box. The temperature of the components inside the remote control box will increase under the scorching heat of the fire, which may cause the components to be unable to work effectively and normally, affecting the fire extinguishing efficiency of the fire hose. Therefore, it is necessary to design a structure to cool the remote control box on the fire hose.

[0004] After searching, Chinese patent publication number CN201320251199.6 discloses a fire hose discharge device with a self-cooling function; a branch outlet pipe is connected to the water discharge nozzle head, a wide-angle nozzle is provided at the water outlet end of the branch outlet pipe, and a water control switch is provided on the branch outlet pipe; a closed rotary cover is provided at the front end of the outlet pipe, a front nozzle is provided at the front end of the rotary cover, and a side nozzle is provided on the side of the rotary cover; a rotating shaft is provided at the front of the outlet pipe, a rotating blade is installed on the rotating shaft, and the rotating blade is provided in the outlet pipe, and the two ends of the rotating shaft are respectively connected to the transmission rod through a gear transmission group, and the other end of the transmission rod is connected to the inner wall of the rotating cover;

[0005] The fire hose in the above patent is equipped with rotating blades through a transmission rod and a rotating shaft. The water pressure inside the fire hose is relatively high. The obstruction of the rotating shaft and the rotating blades will affect the water discharge efficiency of the hose. Moreover, the hose in the above patent cannot adjust the spraying pressure. In this way, when facing different fires, the fire hose in the above patent can only spray at one pressure and cannot effectively complete the spraying operation needs. Utility Model Content

[0006] The purpose of the present utility model is to provide a fire-fighting water gun with a cooling function. In this structure, the water inlet of the water gun body is effectively connected to the fire belt on the drone or the ladder, and the water gun body and the nozzle are transported to the vicinity of the fire by the drone or the ladder. The electronic components inside the remote control box on the water gun body are used to effectively switch the spraying mode of the nozzle, thereby ensuring work efficiency. When the electronic components inside the remote control box are subject to temperature changes, the solenoid valve inside the water inlet adapter is opened through the temperature sensor, so that a part of the water in the water gun body enters the inner wall of the cooling tank, and the water-blocking plate is used to increase the retention time of the water inside the cooling tank, thereby achieving a cooling effect; so as to solve the problems of the above-mentioned background technology.

[0030] The remote control box 5 includes a mounting shell 52; electronic components 53 are disposed within the mounting shell 52; the sidewalls and bottom plate of the mounting shell 52 form a sandwich arrangement, and the cavity of the sandwich is a cooling tank 520; a water blocking plate 521 is integrally provided on the sidewall of the cooling tank 520, and the water blocking plate 521 is disposed at an angle;

[0031] Both ends of the mounting shell 52 are provided with mounting openings for connecting to the water inlet adapter 4 and the water outlet adapter 7;

[0032] By adopting the above technical solution, when in use, the nozzle 2 is clamped to the water delivery end of the water gun body 1, and the water inlet end of the water gun body 1 is connected to the fire hose to achieve the effect of fire sprinkler. During the spraying process, the electronic components 53 inside the remote control box 5 can effectively adjust the water pressure of the nozzle 2 to meet the needs of different fire severity.

[0033] The cooling tank 520 is connected to the mounting ports at both ends of the mounting shell 52; a sealing cover 51 is fixedly mounted on the top of the mounting shell 52 by bolts; a temperature sensor 510 is fixedly mounted on the bottom of the sealing cover 51; the temperature sensor 510 is electrically connected to the solenoid valve; an indicator plate 50 is integrally provided on the sealing cover 51; and operating buttons are mounted on the sealing cover 51 and the indicator plate 50.

[0034] In this embodiment, a pressure gauge 3 is fixedly mounted on the water gun body 1 through a connector; the pressure gauge 3 is located on the water outlet side of the water gun body 1;

[0035] By adopting the above technical solution, when the water gun body 1 and the nozzle 2 are in operation, the remote control box 5 on the water gun body 1 is exposed to the heat of the fire. When the temperature inside the mounting shell 52 reaches the temperature set by the temperature sensor 510, in order to ensure that the electronic components 53 are not damaged, the temperature sensor 510 opens the solenoid valve inside the water inlet adapter 4 on the water gun body 1, so that a portion of the water inside the water gun body 1 enters the cooling tank 520 through the water inlet adapter 4 and the mounting port on the remote control box 5. A water blocking plate 521 is obliquely provided on the side wall of the cooling tank 520.

When the temperature inside the mounting shell 52 reaches the temperature set by the temperature sensor 510, in order to ensure that the electronic components 53 are not damaged, the temperature sensor 510 opens the solenoid valve inside the water inlet adapter 4 on the water gun body 1, so that a portion of the water inside the water gun body 1 enters the cooling tank 520 through the water inlet adapter 4 and the mounting port on the remote control box 5. A water blocking plate 521 is obliquely provided on the side wall of the cooling tank 520. The water blocking plate 521 effectively increases the retention time of water in the cooling tank 520, thereby achieving a cooling effect.
