Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire protection technology, specifically to a water cannon auxiliary aiming device. Background Technology
[0002] Water cannons are fixed fire extinguishing devices that use water as the extinguishing medium to extinguish fires from a distance. Currently, in fire rescue operations involving high-rise buildings, chemical plants, and large-span structures that require long-distance water spraying, firefighters face a dilemma when operating mobile and vehicle-mounted fire cannons: difficulty in pressure control and difficulty in aiming. This leads to slow deployment and significant water loss. Specifically, existing mobile and vehicle-mounted fire cannons sometimes fail to accurately target the fire on the first shot, resulting in wasted water. Utility Model Content
[0003] In view of the problems existing in the prior art, this utility model discloses a water cannon auxiliary aiming device. The technical solution adopted is that it includes a water cannon, and two brackets are fixedly installed on the side of the water cannon outlet. An aiming light is locked in the brackets, and a tensioning mechanism is installed on both brackets.
[0004] The aiming light includes a lens, a laser emitting module, a housing, a battery, and a control button. The laser emitting module is fixedly installed in a groove at one end of the housing, and a transparent lens is fixedly installed at the opening of the groove at one end of the housing. The battery is fixedly installed inside the housing, and a control button is fixedly installed on the end face of the other end of the housing. The battery is electrically connected to the laser emitting module through the control button. The tensioning mechanism includes a hook, a rubber band, a fixing groove, and a pull ring. The hook is fixedly installed on the side of the mounting base. One end of the rubber band is fixedly connected to the other side of the mounting base. The side of the rubber band has at least three fixing grooves that cooperate with the hook. The other end of the rubber band is fixedly connected to the side of the pull ring. The opening in the middle of the mounting base has a groove that cooperates with the rubber band.
[0005] As a preferred embodiment of this utility model, a rubber cover is fixed on the end face of the outer shell away from the lens, and the rubber cover is located outside the control button.
[0006] As a preferred embodiment of this invention, one of the two aiming lights emits a red laser, and the other aims light emits a green laser.
[0007] As a preferred embodiment of this invention, the card holder is made of polypropylene.
[0008] As a preferred embodiment of this utility model, the outer shell is composed of an outer layer and an inner layer joined together, wherein the outer layer is made of glass fiber and the inner layer is made of ceramic fiber.
[0009] The beneficial effects of this utility model are:
[0010] 1. This utility model can emit a laser beam through a laser emission module to help the operator quickly and accurately lock the target position, enabling the water cannon to be aimed quickly, improving the accuracy of the first shot, avoiding waste of water resources, and the aiming light is easy to install and remove without affecting the normal use of the water cannon. The aiming light can be firmly fixed on the bracket by the cooperation of rubber band and hook, avoiding aiming deviation caused by shaking or vibration during use.
[0011] 2. The rubber cover prevents water from entering the aiming light through the control button during use and causing damage, thus improving the aiming light's waterproof capability.
[0012] 3. The polypropylene mounting base has the advantages of being resistant to deformation and combustion in high-temperature environments, improving stability during use. The outer layer made of glass fiber is resistant to high temperature and high pressure, while the inner layer made of ceramic fiber is flame-retardant, thus preventing damage to the aiming light during use.

Detailed Implementation
[0020] Example 1
[0021] like Figures 1 to 6As shown, this utility model discloses a water cannon auxiliary aiming device. The technical solution adopted is as follows: it includes a water cannon 1, and two brackets 2 are fixedly installed on the side of the water outlet of the water cannon 1. The brackets 2 are made of polypropylene. Polypropylene brackets 2 have the advantages of not being easily deformed or burned in high-temperature environments, which improves the stability during use. Aiming lights 3 are fixedly connected inside the brackets 2. One aiming light 3 emits a red laser, and the other aiming light 3 emits a green laser. Each bracket 2 is equipped with a tensioning mechanism 4. The aiming light 3 includes a lens 31, a laser emitting module 32, a housing 33, a battery 34, and a control button 35. The laser emitting module 32 is fixedly installed in the groove at one end of the housing 33. A transparent lens 31 is fixedly installed at the opening of the groove at one end of the housing 33. The battery 34 is fixedly installed inside the housing 33. The control button 35 is fixedly installed on the end face of the other end of the housing 33. The housing 33 is composed of an outer layer 331 and an inner layer 332. The device is composed of a composite material, with an outer layer 331 made of fiberglass and an inner layer 332 made of ceramic fiber. The fiberglass outer layer 331 is resistant to high temperature and high pressure, while the ceramic fiber inner layer 332 is flame-retardant, thus preventing damage to the aiming light 2 during use. The battery 34 is electrically connected to the laser emitting module 32 via the control button 35. A rubber cover 5 is fixed on the end face of the outer shell 33 away from the lens 31. The rubber cover 5 is located outside the control button 35. The rubber cover 5 can prevent water from entering the aiming light 3 from the control button 35 during use and causing damage to the aiming light 3, thereby improving the waterproof capability of the aiming light 3. The laser emitting module 32 can emit a laser beam to help the operator quickly and accurately lock the target position, enabling the water cannon 1 to be aimed quickly, improving the accuracy of the first shot of the water cannon 1, avoiding waste of water resources, and the aiming light 3 is easy to install and remove without affecting the normal use of the water cannon.
[0022] The tensioning mechanism 4 includes a hook 41, a rubber band 42, a fixing groove 43, and a pull ring 44. The hook 41 is fixedly installed on the side of the mounting base 2. One end of the rubber band 42 is fixedly connected to the other side of the mounting base 2. The side of the rubber band 42 has at least three fixing grooves 43 that cooperate with the hook 43. The other end of the rubber band 42 is fixedly connected to the side of the pull ring 44. The opening in the middle of the mounting base 2 has a groove that cooperates with the rubber band 42. Through the cooperation of the rubber band 42 and the hook 41, the aiming light 42 can be firmly fixed on the mounting base 2, avoiding aiming deviation caused by shaking or vibration during use.
[0023] The working principle of this utility model is as follows: Two aiming lights 3 are respectively inserted into two brackets 2. Pulling the pull ring 44 causes the rubber belt 42 to bend upward. Tighten the rubber belt 42 and hang the hook 41 in the fixing groove 43 at a suitable position on the rubber belt 42, so that the rubber belt 42 tightens the aiming lights 3. Press the control button 35 to connect the circuit between the battery 34 and the laser emitting module 32, so that the laser emitting module 32 works to emit red and green beams. Through the red and green beams, the operator can quickly point the muzzle of the water cannon 1 toward the fire point, so that the first shot of the water cannon 1 can directly hit the fire point, avoiding the first shot of the water cannon 1 from going astray and delaying the fire extinguishing opportunity, and also avoiding the waste of water resources.
