Description

underwater laser warning device

technical field

The invention relates to a warning device, in particular to an underwater laser warning device.

Background technique

At present, most of the existing warning devices in life are placed on the ground or above the water surface. There is no warning device that can be installed underwater. There is almost no warning for underwater dangerous situations, especially when floods occur in cities. event.

Contents of the invention

Aiming at the deficiencies in the prior art, the present invention proposes an underwater laser warning device, which can realize the warning of underwater dangerous terrain, such as the safety hazard caused by the lack of manhole covers in streets during urban floods.

In order to achieve the purpose of the present invention, the technical solution adopted in the present invention is: an underwater laser warning device, including a warning device body, a controller, a power supply and a laser light group driving circuit inside the warning device body, and the inside of the top of the warning device body There is a laser light group, the laser light group is irradiated from the bottom to the water surface, and the light is scattered through the underwater and water surface to form a warning area. There are pressure sensors on both sides of the warning body, and the pressure sensor is connected to the controller to convert the water pressure into an electrical signal. Passed to the controller, the laser light group is connected with the laser light group driving circuit, the laser light group driving circuit is connected with the power supply and the controller, and the controller controls the laser light group to be pulsed on.

The pressure sensor is a capacitive pressure sensor. The alarm body is provided with a sealed waterproof casing, and the top of the waterproof casing is transparent.

The bottom of the underwater laser warning device is provided with a base, and the base is fixed on the ground surface by a fixing bolt, and the fixing bolt is adjusted by a wrench on it.

The invention has the beneficial effects of simple structure, low cost, convenient application and obvious warning effect, and is very suitable for warning some underwater safety hazards in urban floods.

Description of drawings

Fig. 1 is a schematic structural view of the present invention.

Detailed ways

Below in conjunction with accompanying drawing and embodiment thereof, the present invention is described in further detail:

As shown in Figure 1, an underwater laser warning device includes a warning device body 1, a laser light group 2, a pressure sensor 3, a controller 4, a power supply 5, a laser light group driving circuit 6, a base 7, and fixing bolts 8, wrench9.

The alarm body 1 is provided with a sealed waterproof casing, and the top of the waterproof casing is transparent. There is a laser light group 2 inside the top of the alarm body 1, a pressure sensor 3 on both sides of the alarm body 1, a controller 4, a power supply 5 and a laser light group driving circuit 6 inside, the pressure sensor 3 is connected to the controller 4, and the water The voltage is converted into an electrical signal and transmitted to the controller. The laser lamp group 2 is connected to the laser lamp group driving circuit 6, and the laser lamp group driving circuit 6 is connected to the power supply and the controller. The controller controls the laser lamp group 2 to be pulsed on.

There is a base 7 at the bottom of the warning device, and the base 7 is fixed on the ground surface by a fixing bolt 8, and the fixing bolt 8 can be adjusted tightness by a wrench 9.

Tighten the fixing bolt 8 with a wrench 9 to fix the base 7 on the ground surface. When the pressure felt by the pressure sensor 3 reaches a certain upper limit, the controller 4 controls the driving circuit to supply power to the laser light group 2, and the laser light group 2 emits red laser light from the underwater Shooting towards the water surface, thus forming an obvious red warning area.

The working principle of the present invention: the pressure sensor converts the water pressure into an electrical signal and transmits it to the controller. When the pressure exceeds a certain threshold, the controller controls the drive circuit to drive multiple high-power laser lights. The laser lights shine from the bottom of the water to the water surface, and the light passes through the water. Scattering below and on the water surface forms an obvious warning area. Among them, the controller controls the laser light to adopt the pulse lighting method, and the light is turned on periodically every second, which greatly reduces power consumption, makes the warning device work for a long time, and reduces the frequency of charging the battery, which is convenient to use.
