Rapid fire protection system for electric vehicles suitable for garages, repair shops, or parking lots

Abstract

This utility model relates to the field of fire protection equipment technology, and in particular to a rapid fire protection system for electric vehicles suitable for garages, repair shops, or parking lots. It includes: a fire-resistant curtain, comprising a curtain fabric and rollers, with the upper end of the curtain fabric fixed and the rollers fixed to the lower end of the curtain fabric; a drive mechanism, comprising a motor; a slide rail, vertically arranged, with the motor slidably mounted on the slide rail, and the output shaft of the motor being connected to the transmission of the rollers; and a control system, electrically connected to the drive mechanism. This utility model mounts the motor at the lower end of the curtain fabric, which not only allows the entire curtain fabric to be stably lowered to a predetermined position via the slide rail, but also provides a counterweight on the slide rail to increase gravity, enabling the curtain fabric to descend more stably and faster on the slide rail, thus extending the service life of the curtain fabric.

Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a rapid fire protection system for electric vehicles suitable for garages, repair shops or parking lots. Background Technology

[0002] Fire curtains are fire prevention devices commonly used in garages, repair shops, parking lots, and other similar locations. They are used to isolate fire-affected areas and prevent the fire from spreading outwards. They are characterized by fire resistance, flame retardancy, and rapid response.

[0003] Traditional fire curtains in parking lots mostly adopt a vertical lifting type, such as the fire prevention and control system and method for electric vehicles in parking lots (publication number CN118491008A) and the fire protection device and control method for electric vehicles in parking lots (publication number CN118949318B). The fire curtains in these cases generally have one end wound around a roller fixed to the ceiling, and the roller is connected to a motor for driving the roller to rotate. The end of the fire curtain that hangs down naturally is equipped with a counterweight. When a fire occurs, the motor drives the roller to rotate forward to lower the curtain. After the fire scene is dealt with, the motor drives the roller to rotate in reverse to roll the curtain back to its initial position.

[0004] Although the existing technical solutions mentioned above have achieved rapid response and descent of the fire curtain, they still have the following defects: the side of the curtain has no limit mechanism, and the curtain falls by relying on the counterweight block at the end to increase gravity or other external forces. During the descent, the curtain may be affected by the wind or heat wave of the flames in the field, causing the descent trajectory to be skewed and the curtain to twist. The end of the fire curtain may fail to land in the predetermined position, affecting the effectiveness of the fire curtain. Utility Model Content

[0005] The purpose of this invention is to provide a rapid fire protection system for electric vehicles suitable for garages, repair shops, or parking lots, solving the problem that the fire curtain cannot descend to the predetermined position, thus preventing the fire curtain from achieving its intended effect.

[0006] The present invention adopts the following technical solution:

[0007] Rapid fire protection systems for electric vehicles suitable for garages, repair shops, or parking lots include:

[0008] A fire-resistant curtain, comprising a curtain fabric and a roller, wherein the upper end of the curtain fabric is fixed and the roller is fixed to the lower end of the curtain fabric;

[0009] The drive mechanism includes a motor;

[0010] A slide rail is provided, which is vertically arranged. The motor is slidably mounted on the slide rail, and the output shaft of the motor is connected to the transmission of the roller.

[0011] A control system, which is electrically connected to the drive mechanism.

[0012] Furthermore, the slide rail consists of two U-shaped groove slide rails, with a slider slidably mounted on the slide rail, and the motor is mounted on the slider.

[0013] Furthermore, the slider is provided with a rolling bearing, which is connected to the other end of the roller.

[0014] Furthermore, the slider is provided with a counterweight that matches the mass of the motor.

[0015] Furthermore, the system includes sensors, which include a composite smoke and heat sensor and a flame video monitoring detector, and the sensors are electrically connected to the control system.

[0016] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages:

[0017] This invention places the motor at the lower end of the curtain, which can prevent the curtain from tilting due to heat waves or wind when it falls during a fire, thus preventing it from falling to the intended position. Compared with the prior art, this structure is more stable and ensures the stability of the curtain's descent position. At the same time, the slider is equipped with a counterweight and a motor to increase gravity, so that the curtain can descend stably on the track and respond quickly, thus extending the service life of the curtain.

[0019] Figure 2 for Figure 1 Sectional view along direction AA.

[0020] Figure 3 This is a side view of the curtain fabric of this utility model.

[0021] The components in the diagram are labeled as follows: curtain 10, fixing seat 11, roller 20, slide rail 31, slider 32, motor 40, mounting seat 41, and rolling bearing 50. Detailed Implementation

[0022] The specific implementation of the present invention will now be described with reference to the accompanying drawings.

[0023] Reference Figure 1A rapid fire protection system for electric vehicles suitable for garages, repair shops or parking lots is installed in parking spaces. The fire curtain includes a curtain 10 and rollers 20. A mounting base 11 is installed on the ceiling. The upper end of the curtain 10 is installed on the mounting base 11. The rollers 20 are located at the lower end of the curtain 10 and extend to both sides of the curtain 10.

[0024] The slide rail 31 is a U-shaped groove slide rail, symmetrically and vertically arranged on both sides of the curtain 10. The two ends of the slide rail 31 are connected to the ceiling and the floor respectively. The sliders 32 are slidably arranged on the slide rail 31. The two sliders 32 are provided with mounting seats 41. One mounting seat 41 is fixedly mounted with a drive mechanism, which includes a motor 40. The other mounting seat 41 is fixedly mounted with a rolling bearing 50. In particular, the motor 40 is preferably a thin yarn motor.

[0025] Reference Figure 1 , Figure 2 and Figure 3 One end of the roller 20 is connected to the tulle motor 40, and the other end is connected to the rolling bearing 50. The motor 40 is electrically connected to the control system. When the motor 40 is driven, the roller 20 rotates and rolls up the curtain 10, which is then returned to the fixed seat 11 on the ceiling via the slide rail 31 and the slider 32.

[0026] Meanwhile, a composite smoke and heat sensor and a flame video monitoring detector are installed directly above the parking space. Both the composite smoke and heat sensor and the flame video monitoring detector are electrically connected to the control system to monitor for fires and transmit signals to lower the curtain 10.

[0027] When using this utility model,

[0028] The curtain 10 is rolled up and fixed to the ceiling mounting base 11 by the motor 40. When a fire occurs, the flame video monitoring detector monitors the fire situation, and the composite smoke and heat sensor transmits signals to the control system. The control system controls the motor 40 to move along the slide rail 31 from the upper end to the lower end of the slide rail 31, thereby opening the curtain 10 to isolate the flames. After the fire is extinguished, the control system drives the motor 40 to rotate, which drives the roller 20 to roll the curtain 10 back to the ceiling mounting base 11.

[0029] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
