[0002] The fire audible and visual alarm is an important component in the fire safety system, with dual warning functions of sound and light. It can receive signals from triggering devices such as fire detectors in real time. Once a fire occurs, it will quickly emit a high-decibel sound and flashing lights to remind people to evacuate and attract attention. There are clear requirements for its installation spacing, position, and angle to ensure timely and accurate transmission of fire information.

[0003] Existing audible and visual alarm detection devices for medium and small-sized fire protection maintenance generally use a sound level meter to check the sound emitted by the audible and visual alarm. During the detection process, a certain distance is required for detection, and the existing detection method is an estimated detection, resulting in errors in the detection effect. Summary of the Utility Model

[0004] In order to overcome the shortcoming that the existing medium and small-sized fire protection maintenance devices lack a scientific quantification mechanism when measuring the effective range of use of the audible and visual alarm, resulting in judgment errors in the applicable range of the audible and visual alarm, the technical problem of the utility model is: to provide an audible and visual alarm detection device for high-precision fire protection maintenance.

[0005] The technical implementation scheme of the utility model is: an audible and visual alarm detection device for high-precision fire protection maintenance, including a detection vehicle, the detection vehicle is configured with driving wheels and moving wheels, and also includes a wire reel, a winding shaft, a winding rope, a positioning plate, a servo motor, and a sound level meter. The servo motor is fixed on the side of the detection vehicle, the output shaft of the servo motor is connected to the winding shaft, the wire reel is fixedly connected to the winding shaft, the winding rope is wound on the wire reel, the positioning plate is placed on the detection vehicle, the end of the winding rope is fixed to the positioning plate, and the sound level meter is fixed on the detection vehicle.

[0006] In addition, particularly preferably, it further includes a first gear and a second gear. The first gear is fixed at the end of the winding shaft, the second gear is fixed at the rotating shaft of the driving wheel, and the first gear meshes with the second gear.

[0007] In addition, particularly preferably, it further includes a warning light, and warning lights are provided on both the detection vehicle and the positioning plate.

[0008] In addition, particularly preferably, it further includes a handle, and a handle is provided on the detection vehicle.

[0009] In addition, particularly preferably, it further includes rollers, the rollers are arranged inside the detection vehicle, and the rollers can be in frictional contact with the winding rope.

[0010] In addition, it is particularly preferred that a protective cover is further included, and the protective cover is fixed to the side of the detection vehicle, specifically located outside the first gear and the second gear.

[0011] The beneficial effects achieved by the present utility model are as follows: taking the acoustic-optic alarm as a starting point, the servo motor is turned on to drive the wire reel to rotate and pay out the wire. At the same time, the driving wheel is driven to rotate through the first gear and the second gear, thereby driving the detection vehicle to move forward. When the detection vehicle moves to a suitable position, the length of the winding rope is measured. Then, the acoustic-optic alarm is turned on, and the sound level meter receives and gives feedback on the sound and light, so as to judge the working state and working ability of the acoustic-optic alarm.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0017] Embodiment: An acoustic-optic alarm detection device for high-precision fire protection maintenance, as Figures 1 - 3As shown in the figure, it includes a detection vehicle 1, which is equipped with driving wheels 9 and moving wheels 10. It also includes a wire reel 2, a winding shaft 201, a winding rope 3, a positioning plate 4, a servo motor 5 and a sound level meter 6. The servo motor 5 is fixed on the side of the detection vehicle 1. The output shaft of the servo motor 5 is connected to the winding shaft 201. The wire reel 2 is fixedly connected to the winding shaft 201. The winding rope 3 is wound on the wire reel 2. The positioning plate 4 is placed on the detection vehicle 1. The end of the winding rope 3 is fixed to the positioning plate 4. The sound level meter 6 is fixed on the detection vehicle 1. Remove the positioning plate 4 and place it at the sound and light alarm, and then push the detection vehicle 1 to move. During this period, the wire reel 2 continuously pays out the wire. By measuring the length of the winding rope 3, the distance between the detection vehicle 1 and the sound and light alarm can be determined. Then start the sound and light alarm, measure the sound decibels through the sound level meter 6, and then judge the actual working ability of the sound and light alarm, so as to achieve the effect of detecting the sound and light alarm.

[0018] As Figure 3 shown, it also includes a first gear 7 and a second gear 8. The first gear 7 is fixed at the end of the winding shaft 201, and the second gear 8 is fixed at the rotating shaft of the driving wheel 9. The first gear 7 and the second gear 8 are meshed with each other.

[0019] As Figure 1 shown, it also includes a warning light 11. Warning lights 11 are provided on both the detection vehicle 1 and the positioning plate 4.

[0020] As Figure 1 shown, it also includes a handle 12. A handle 12 is provided on the detection vehicle 1, which is convenient for the staff to move, pick up and place this device.

[0021] As Figure 1 shown, it also includes a roller 13. The roller 13 is arranged inside the detection vehicle 1. The roller 13 can be in frictional contact with the winding rope 3. The roller 13 effectively reduces the friction coefficient between the winding rope 3 and the detection vehicle 1, so that the winding rope 3 can be smoothly led out.

[0022] As Figure 1 shown, it also includes a protective cover 14. The protective cover 14 is fixed on the side of the detection vehicle 1, specifically located outside the first gear 7 and the second gear 8.

A placement groove is provided at the rear side of the detection vehicle 1 for placing the positioning plate 4. The staff moves the detection vehicle 1 to the sound and light alarm, places the positioning plate 4 on the ground, and then turns on the servo motor 5 to drive the wire reel 2 to rotate through the winding shaft 201. At the same time, the first gear 7 located at the end of the winding shaft 201 will drive the driving wheel 9 to rotate synchronously through the second gear 8. The driving wheel 9 will drive the detection vehicle 1 to move forward, and the winding rope 3 will also be unwound. When the detection vehicle 1 moves to a suitable position, the servo motor 5 is turned off, and then the sound and light alarm is turned on. The sound and light alarm provides sound and light at the positioning plate 4. The sound volume is quantified by the sound level meter 6, and then the working state and ability of the sound and light alarm are judged. The distance between the sound and light alarm and the sound level meter 6 is accurately measured through the length of the winding rope 3.
