Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to fire extinguishing systems for parking lots, and is particularly applicable to sidewall springs. This invention relates to a fire extinguishing system for a parking lot equipped with a parking lot.

0002 In recent years, mechanical parking lots have been constructed from the viewpoint of effective use of land. This parking The venue uses elevators and traveling trolleys in the parking section of a multi-tiered parking stage. Although it automatically moves cars in and out, it allows for high-density parking without human intervention. Therefore, it is attracting attention.

0003

[Problem that the idea aims to solve]

In mechanical parking lots, the distance between the vehicles in the parking area and the ceiling is narrow, and regular sprinkling Even if a water sprayer is installed on the ceiling, the necessary watering area cannot be obtained. For this reason, each parking section They are not equipped with fire extinguishing equipment. As a result, a fire occurred in a vehicle stored in the parking area. If this occurs, the fire may spread to vehicles in the vicinity of the vehicle on fire, or a large fire may occur.

0004 Therefore, closed type strips are installed on both sides of the parking section of the parking stage, that is, on both sides of the vehicle. Prinklers are installed facing each other, and in the event of a vehicle fire, closed type sprinklers on both sides are activated. A method is being considered to improve fire extinguishing efficiency by spraying water or foam over the entire vehicle. It will be done.

[0005]

[Problem that the idea aims to solve]

However, with this method, there is a difference in starting between both sprinklers when a fire occurs. When the water is discharged from one sprinkler, the heat-sensitive part of the other sprinkler is cooled down. It will stop working. Therefore, the fire must be extinguished using only the sprinklers on one side. Therefore, fire extinguishing efficiency is extremely low. In addition, in the event of a fire, high-temperature air may reach the ceiling of the parking area. For closed type sprinklers installed on both sides, the sprinklers cannot be placed in the ceiling. Compared to when installed in a well, fire detection is delayed and water discharge starts later. Therefore , initial fire extinguishing becomes difficult.

[0006] In view of the above circumstances, this idea was developed to quickly and simultaneously remove the sidewalls in the event of a fire. The purpose is to make the sprinklers work.

[0007]

[Means to solve the problem]

This invention consists of a parking stage having a parking section, and a parking stage provided at the top of both sides of the parking section. an open sprinkler installed on the ceiling of the parking area; and an open sprinkler installed on the ceiling of the parking area. A fire extinguishing system for a parking lot, comprising: a fire detector that activates a fire alarm; This aims to achieve the above objective.

[0008]

[Effect]

If a fire breaks out in a parked vehicle, a fire detector installed on the ceiling of the parking area will detect the fire. When a fire is detected, the open sprinklers on both sides of the parking area are activated simultaneously, and the fire is detected. Sprinkle fire extinguishing water towards both sides of the area.

【Example】

An embodiment of this invention will be explained with reference to the attached drawings, and the same drawing numerals also indicate the names. The functions are also the same. As shown in Figures 1 and 2, a mechanical parking lot 1 has multiple parking sections 2. A plurality of parking stages 3 are provided. On the side of this parking stage 3 , a conveyance path 6 for the traveling cart 5 that slides on the rails 4 is provided, and this conveyance path 6 is It is connected to the vertical path 9 of the elevator 8. Both sides of each parking section 2 of parking stage 3 At the top of the section, as shown in Figures 1 and 3 to 5, there is an open side wall spring. 51 are provided facing each other, and in the center of the ceiling surface there is a terminal connected to the control device C. A fire detector W is installed.

0010 The open type sidewall sprinkler 51 sprinkles fire extinguishing water such as water or foam solution into water. Discharges from a square direction toward the foot of the head, spreading over a fan-shaped or rectangular scattering area. It is a sprinkler that sprays water. Figures 6 and 7 are open side wall springs. In the front and side views of one embodiment of the rubber 51, the fire extinguishing water discharged from the nozzle part 52 is collides with the L-shaped deflector 53 provided above (or below) the nozzle part 52. It is deflected by the beam and scattered in a horizontal or rectangular area from the front to the sides. In addition, The shape of the scattering is determined by the shape of the deflector 53, and in this example, it is close to a rectangle. Spray in a fan-shaped area.

[0011] Next, the operation of this embodiment will be explained. When a fire occurs, the hot air flows into the parking area 2. fire detector W detects the fire and issues a fire signal. believe This fire signal causes the control device C to control the open side windows at the top of both sides of the parking area. Since water is discharged from the wall sprinkler 51 at the same time, fire extinguishing water is distributed to the water discharge areas A1 and A. 2 The fire was ejected towards the fire vehicle 20 inside, covering the entire fire vehicle, and the fire was extinguished. Ru.

0012 The embodiment of this invention is not limited to the above, but for example, as shown in FIG. A descending disaster prevention curtain 12 is installed on the ceiling of each parking section 2, and the disaster prevention curtain 12 is installed on the ceiling of each parking section 2. 12 may be lowered to surround and seal the fire extinguishing space F; The sides where the rails are installed may be at the front or rear of the vehicle.

[0013] In addition, as an open sprinkler head, it is an open sprinkler head with a generally circular spray area. As shown in Figures 8 and 9, an open sprinkler head is used to connect the adjacent parking lot. If the fire detector W detects a fire in the parking section 2, The open sprinkler 54 installed at the top of the boundary area on both sides of the parking area 2 It may also be possible to spray water from the In this way, not only the fire vehicle but also the adjacent parked vehicle can Fire extinguishing water will also be sprayed on vehicles in the parking area to prevent the fire from spreading to adjacent parking areas. can do.

[0014]

[Effect of the idea]

This invention is constructed as described above, so the fire detector detects both sides of the parking area. The top open sprinkler can be activated at the same time. Therefore, closed type Unlike when using sprinklers, only one sprinkler does not operate. Therefore, both sprinklers can be operated quickly and reliably. Also, the ceiling Since a fire detector is installed on the surface, fires can be detected faster than before. subordinate Therefore, with this invention, it is possible to extinguish a fire in its early stages.
