Abstract

The utility model provides a safety warning light suitable for garages, which includes components such as a warning light, a photoelectric switch, and a time relay. The warning light is composed of a light box, a light bulb, a sunshade, a hook, a time relay, and an adjustment button. The warning light is placed on the garage door, and the photoelectric switch is placed on the walls on both sides of the warning light. When the vehicle enters and exits, the emitted light is blocked, the receiving body conducts the time relay to pull in, the warning light is on, and after a certain time delay by the time relay, the light is delayed to turn off. Using the working principle of the photoelectric switch, the warning light is controlled by the delay of the time relay to warn the vehicles entering and exiting to pay attention to safety. The utility model has the advantages of reasonable structural design, low cost, easy manufacture, convenient use and good warning effect.

Description

Warning Light

technical field

The utility model belongs to the technical field of safety protection facilities according to the national patent classification table (IPC), and particularly relates to a safety warning light suitable for garages.

Background technique

At present, along with the increase in car ownership, collision accidents between vehicles entering and leaving garages or large parking lots also occur from time to time, causing great harm to people's lives and properties. In order to reduce the occurrence of accidents, reflective warning signs are generally used in large parking lots to warn according to the reflection of lights. Its disadvantage is that due to passive reflection, the reflection of light is poor under harsh weather conditions such as rainy and foggy days, and it is difficult to work. In addition, the reflected light of this kind of reflective warning sign has a relatively short penetration distance. For high-speed vehicles, the driver does not have enough time to take measures such as avoidance, deceleration or braking to avoid vehicle collision accidents.

In order to solve this problem, the patent No. 01220474.9 discloses a "highway parking warning light", which includes a power supply, a lamp holder, a lamp and a switch, and is provided with an oscillating circuit. The lamp is a light-emitting diode, and the oscillating circuit is composed of a triode, a capacitor, and a resistor to form a multivibrator. The output of the collector of the diode passes through a current-limiting resistor, and the light-emitting diode is connected to a switch. The structure of this kind of warning light is relatively complicated, and it is not suitable for the safety warning of the garage.

Contents of the invention

The purpose of this utility model is to provide a safety warning light for the garage, including warning lights, photoelectric switches, time relays and other components, using the working principle of the photoelectric switch to control the shutdown of the warning lights through the time delay of the time relay, so as to warn the entry and exit Vehicles pay attention to safety.

The utility model is achieved in that:

The warning light is composed of a light box, a light bulb, a shade, a hook, a time relay, an adjustment button and other components.

The photoelectric switch is composed of two parts: a luminous body and a receiving body, and the distance is 5 to 8 meters;

The warning light is placed on the garage door, the photoelectric switch is placed on the walls on both sides of the warning light, the luminous body is placed on the left side of the garage door, and the receiver is placed on the right side of the garage door. When a vehicle enters or exits, the emitted light is blocked, the receiving body conducts the time relay to pull in, the warning light is on, and after a delay of 1 to 60 seconds (adjustable) by the time relay, the light is delayed to turn off. Voltage selection 24 ~ 36 volts safe voltage.

The utility model has the following advantages:

1. Reasonable structural design, low cost, easy to manufacture;

2. Small size, light weight, easy to use and maintain;

3. Effectively prevent the collision accidents of vehicles entering and leaving the garage, and ensure the safety of people and vehicles;

Detailed ways

The utility model is described in detail in conjunction with the embodiment in Fig. 1 and Fig. 2:

The utility model mainly includes components such as a warning light, a photoelectric switch, and a time relay.

The warning light comprises a light box 1, a light bulb 2, a sunshade 3, a hook 4, a time relay 5, and an adjustment button 6. Light box 1, shade 3 and hook 4 are made of thin steel plates, and light bulb 2 is made of red color. The time relay 5 is placed in the light box 1, and the adjustment button 6 is placed under the time relay 5.

The distance of the photoelectric switch is 8 meters, and the time delay of the time relay 5 is set as 50 seconds, and the voltage is 30 volts.

The warning light is placed above the garage door, the photoelectric switch is installed on the walls on both sides of the warning light, the luminous body is placed on the left side, and the receiver is placed on the right side.

When the vehicle enters and exits, the luminous body is blocked, the receiving body conduction time relay is closed, the warning light is on, and after a delay of 50 seconds, the warning light is turned off after a delay.

Claims (1)
