Description

Technical Field

[0001] The utility model relates to the technical field of protective alarm devices, in particular to an optical fiber perimeter protection alarm device. Background Technique

[0002] The system related to optical fiber perimeter protection is an alarm platform based on vibration detection. The sensing optical fiber can be installed on fences, underground or on the top of walls. The vibration caused by an intruder trying to climb and break in will change the mode of the transmitted light. After being analyzed and processed by the signal processing unit, corresponding alarm signals can be issued. At present, in most scenarios, the installation method of surface mounting is still adopted. Although this method is convenient for construction, there are problems such as being easily damaged or sabotaged by humans. Researchers have developed an optical fiber perimeter protection device to protect it. For example, the Chinese authorized utility model patent (publication number: CN217588198U) discloses an optical fiber perimeter protection device. By setting a limiting structure, when it is necessary to disassemble the tempered glass cover outside the sound and light alarm, or when repairing or replacing the internal light-emitting device, the tempered glass cover can be quickly disassembled through the cooperation of the first rotating shaft and other components, which is convenient for repairing or replacing the internal light-emitting device.

[0003] When the above device is in use, there are still some deficiencies: Although the tempered glass cover in the above device can block most of the rainwater, since the tempered glass cover usually needs to be provided with sound outlet holes to ensure the transmission of sound, these sound outlet holes often become the main way for rainwater to penetrate in rainy days. After the rainwater penetrates, it may cause the internal circuit of the sound and light alarm to be affected by moisture, thereby affecting its normal operation and even shortening its service life. Therefore, an optical fiber perimeter protection alarm device is proposed for the above situation. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcoming that the internal circuit of the sound and light alarm may be affected by moisture after rainwater penetration in the prior art, thereby affecting its normal operation, and to propose an optical fiber perimeter protection alarm device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An optical fiber perimeter protection alarm device includes a pair of bases, columns are arranged on both of the pair of bases, support plates are arranged on both of the pair of columns, a sound and light alarm is arranged on the top of the support plate, and a tempered glass cover that covers the sound and light alarm inside is also arranged on the top of the support plate.

[0007] Four first card slots are opened on the top of the support plate, and a pair of drainage grooves are penetrated and opened on the top of the support plate adjacent to the first card slots.

[0008] The top of the tempered glass cover is provided with four second card slots, each of which is plugged with a protective plate, with a gap between the protective plate and the tempered glass cover, the bottom of the protective plate is plugged in the first card slot, and the protective plate is provided with four rows of through holes.

[0009] Preferably, four rows of cross bars are arranged between a pair of upright posts, and luminous warning strips are bonded to the outer surfaces of the upright posts.

[0010] Preferably, the top of the protective plate has a curved portion, the protective plate and the curved portion are integrally formed, the curved portion is in an inverted "凵" shape, and a rubber pad is provided at the end of the curved portion.

[0011] Preferably, a pair of side panels are provided on the protective plate, the side panels are integrally formed with the protective plate, and one end of the side panel away from the protective plate is in contact with the surface of the tempered glass cover.

[0012] Preferably, four baffles are arranged on the surface of the protective plate, and the baffles are arranged to be inclined downward.

[0013] Preferably, a sound outlet hole is provided on the surface of the tempered glass cover.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model can effectively prevent rainwater from penetrating into the tempered glass cover through the sound outlet holes on the tempered glass cover to affect the normal operation of the sound and light alarm through the structural design of the first card slot, the second card slot, the protective plate and the side plate, thereby significantly improving the waterproof performance of the device, reducing the risk of damage to the sound and light alarm due to rainwater penetration, extending the service life of the sound and light alarm, and also reducing the maintenance workload and working costs of the staff.

[0016] 2. The utility model can prevent rainwater from flowing into the tempered glass cover through the through holes in windy and rainy weather through the structural design of the drainage groove, the protective plate and the baffle. At the same time, since there is a gap between the protective plate and the tempered glass cover, a small amount of rainwater that flows into the space between the protective plate and the tempered glass cover through the through holes can also be discharged through the drainage groove, thereby further preventing rainwater from penetrating into the tempered glass cover, thereby enhancing the overall waterproof performance of the device.
