Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sound and light alarm devices, specifically a sound and light alarm device for flood prevention and early warning in reservoirs. Background Technology
[0002] As an important infrastructure for flood control and disaster reduction, the reliability of the safety monitoring and early warning system of reservoirs is crucial. In the existing reservoir flood control system, the audible and visual alarm device, as the terminal equipment that directly transmits the danger to the surrounding area, needs to be exposed to the complex outdoor environment for a long time and faces multiple challenges such as rainwater erosion, silt impact, and dust accumulation.
[0003] Traditional sound and light alarm devices are mostly open-type, which makes it easy for rainwater and silt to seep into the device, causing short circuits in the lighting components and seriously affecting the service life of the device. The sound port is easily covered by dust and debris during long-term use, which obstructs sound transmission, reduces the effectiveness of the warning signal, and may even cause warning delays or failures. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an audible and visual alarm device for reservoir flood prevention early warning, which solves the problem that traditional audible and visual alarm devices lack protective structures and are easily damaged.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A reservoir flood control early warning audible and visual alarm device includes: a support structure, an audible and visual alarm fixedly connected to the outer wall of the support structure, and a protective structure slidably connected to the inner wall of the support structure; the protective structure includes a protective frame, a transparent plate fixedly connected to the outer wall of the protective frame, limit rods symmetrically fixedly connected to the outer wall of the protective frame, a pull plate slidably connected to the outer wall of the limit rods, a fixing block fixedly connected to the outer wall of the pull plate, compression springs symmetrically fixedly connected to the outer wall of the pull plate on the side away from the fixing block, and a filter screen fixedly connected to the inner wall of the protective frame on the side closer to the transparent plate.
[0009] Preferably, the filter screen is located below the transparent plate, and the outer wall of the compression spring on the side away from the pull plate is fixedly connected to the outer wall of the limiting rod. When the pull plate is pulled to slide outward along the limiting rod, the compression spring will be squeezed and stored, which will also drive the fixed block to move.
[0010] Preferably, the outer wall of the protective frame near the filter screen is symmetrically provided with sliding grooves, the inner wall of the sliding groove is fixedly connected with a sliding rod, the outer wall of the sliding rod is slidably connected with a push-pull plate, the bottom outer wall of the push-pull plate is symmetrically fixedly connected with tension springs, and the inner wall of the push-pull plate is fixedly connected with a brush.
[0011] Preferably, the slide grooves are symmetrically arranged on both sides of the filter screen, the outer wall of the push-pull plate is slidably connected to the inner wall of the slide groove, the outer wall of the tension spring on the side away from the push-pull plate is fixedly connected to the inner wall of the bottom of the slide groove, and the outer wall of the brush is in slidable contact with the outer wall of the protective frame and the filter screen. Pulling the push-pull plate causes it to slide up and down along the slide groove via the slide rod, thereby driving the brush to rub the filter screen, remove dust and debris, and prevent the filter screen from clogging and affecting the sound output.
[0012] Preferably, the support structure includes a support rod, a support corner plate is fixedly connected to the outer wall at the bottom of the support rod, a photovoltaic panel is fixedly connected to the outer wall at the top of the support rod, a connecting plate is symmetrically fixedly connected to the outer wall on the side of the support rod by bolts, an mounting plate is fixedly connected to the outer wall of the connecting plate, and a fixing groove is symmetrically formed on the outer wall on the side of the mounting plate.

The inner wall of the fixing groove is slidably connected to the outer wall of the fixing block. The outer wall of the mounting plate is in contact with the outer wall of the protective frame. The position of the sound-blowing port on the audible and visual alarm corresponds to the position of the filter screen to block dust and large particles of debris from entering, while not affecting sound propagation. The position of the light on the audible and visual alarm corresponds to the position of the transparent plate to prevent rainwater, silt, and debris from directly impacting the light assembly.
[0014] (III) Beneficial Effects
[0015] This utility model provides an audible and visual alarm device for flood prevention and early warning in reservoirs. It has the following beneficial effects:
[0016] (i) The protective frame, through the detachable connection of the fixing block and the fixing groove, combined with the elastic reset design of the compression spring, allows for quick disassembly of the protective structure during maintenance by simply pulling the pull plate to remove the fixing block, without the need for complicated tools. After maintenance, the compression spring pushes the fixing block into the fixing groove for quick installation. At the same time, the transparent plate and filter on the protective frame form a physical barrier to protect the audible and visual alarm as well as its external lighting components and broadcast port, reducing damage to the audible and visual alarm caused by external environmental corrosion and significantly extending the service life of the equipment.
[0017] (ii) The push-pull plate, through the cooperation of the brush, tension spring, slide groove and slide rod, constitutes a cleaning system. When the dust on the filter screen affects the sound transmission, pulling the push-pull plate will drive the brush to clean the filter screen. The tension spring helps the push-pull plate to automatically reset, effectively avoiding filter screen blockage, ensuring that the sound and light alarm always maintains clear sound, and ensuring the timely and effective transmission of flood warning signals.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-6This utility model provides a technical solution: a sound and light alarm device for reservoir flood prevention early warning, comprising: a support structure 1, a sound and light alarm 3 fixedly connected to the outer wall of the support structure 1, and a protective structure 2 slidably connected to the inner wall of the support structure 1; the protective structure 2 includes a protective frame 21, a transparent plate 22 fixedly connected to the outer wall of the protective frame 21, a limit rod 23 symmetrically fixedly connected to the outer wall of the protective frame 21, a pull plate 24 slidably connected to the outer wall of the limit rod 23, a fixing block 25 fixedly connected to the outer wall of the pull plate 24, a compression spring 26 symmetrically fixedly connected to the outer wall of the pull plate 24 away from the fixing block 25, and a filter screen 27 fixedly connected to the inner wall of the protective frame 21 near the transparent plate 22.
[0027] The filter screen 27 is located below the transparent plate 22. The outer wall of the compression spring 26 away from the pull plate 24 is fixedly connected to the outer wall of the limiting rod 23. When the pull plate 24 is pulled to slide outward along the limiting rod 23, the compression spring 26 will be squeezed and stored, which will also drive the fixed block 25 to move.
[0028] The outer wall of the protective frame 21 near the filter screen 27 is symmetrically provided with a sliding groove 28. The inner wall of the sliding groove 28 is fixedly connected with a sliding rod 29. The outer wall of the sliding rod 29 is slidably connected with a push-pull plate 291. The outer wall of the bottom of the push-pull plate 291 is symmetrically fixedly connected with a tension spring 292. The inner wall of the push-pull plate 291 is fixedly connected with a brush 293.
[0029] The slide grooves 28 are symmetrically arranged on both sides of the filter screen 27. The outer wall of the push-pull plate 291 is slidably connected to the inner wall of the slide groove 28. The outer wall of the tension spring 292 on the side away from the push-pull plate 291 is fixedly connected to the inner wall of the bottom of the slide groove 28. The outer wall of the brush 293 is in slidable contact with the outer walls of the protective frame 21 and the filter screen 27. Pulling the push-pull plate 291 causes it to slide up and down along the slide groove 28 via the slide rod 29, driving the brush 293 to rub the filter screen 27, removing dust and debris, and preventing the filter screen 27 from becoming clogged and affecting sound production.
[0030] The support structure 1 includes a support rod 11. A support corner plate 12 is fixedly connected to the outer wall of the bottom of the support rod 11. A photovoltaic panel 13 is fixedly connected to the outer wall of the top of the support rod 11. A connecting plate 14 is symmetrically fixedly connected to the outer wall of the side of the support rod 11 by bolts. An installation plate 15 is fixedly connected to the outer wall of the connecting plate 14. Fixing grooves 16 are symmetrically opened on the outer wall of the side of the installation plate 15.
[0031] The outer wall of the mounting plate 15 is fixedly connected to the outer wall of the audible and visual alarm 3 by bolts, and the photovoltaic panel 13 is connected to the audible and visual alarm 3 by a power cord. The inner wall of the fixing groove 16 is slidably connected to the outer wall of the fixing block 25. The outer wall of the mounting plate 15 is in contact with the outer wall of the protective frame 21. The position of the broadcast port on the audible and visual alarm 3 corresponds to the position of the filter screen 27, blocking dust and large particles of debris from entering, while not affecting the sound transmission. The position of the light on the audible and visual alarm 3 corresponds to the position of the transparent plate 22, preventing rainwater, silt, and debris from directly impacting the light component.
[0032] In use, the device is fixedly installed around the reservoir by the support structure 1, and the protective structure 2 can be installed on the outside of the sound and light alarm 3 by the cooperation of the fixing block 25 and the fixing groove 16 to protect it.
[0033] The support rod 11 is fixed to the ground around the reservoir by the support corner plate 12 at the bottom to ensure the stability of the device. The photovoltaic panel 13 at the top of the support rod 11 can generate solar power and power the audible and visual alarm 3 through the power line to achieve sustainable operation. The connecting plate 14 on the side is connected to the mounting plate 15 by bolts to the support rod 11. At the same time, the audible and visual alarm 3 is also connected to the mounting plate 15 by bolts. The fixing groove 16 on the mounting plate 15 is used to cooperate with the fixing block 25 of the protective structure 2 to form a detachable installation structure.
[0034] When it is necessary to disassemble the protective structure 2 to inspect and maintain the internal sound and light alarm 3, the pull plate 24 can be pulled outward and slid outward along the limit rod 23. At this time, the compression spring 26 is squeezed and stored, and the fixing block 25 slides out of the fixing groove 16, releasing the locking between the mounting plate 15 and the protective frame 21. Then disconnect the power line between the photovoltaic panel 13 and the sound and light alarm 3, and the protective structure 2 can be removed from the mounting plate 15 for maintenance. Conversely, the compression spring 26 will push the pull plate 24, causing the fixing block 25 to be inserted into the fixing groove 16, installing the protective structure 2 on the mounting plate 15 and covering the sound and light alarm 3 inside to form a physical barrier. At the same time, the transparent plate 22 covers the light area of the sound and light alarm 3 to prevent rainwater, silt, and debris from directly impacting the light components. The filter 27 covers the sound and light alarm 3's broadcast port to block dust and large particles of debris from entering, while not affecting sound transmission.
[0035] When too much dust and impurities on the filter 27 affect sound transmission, the push-pull plate 291 can be pulled to slide up and down along the slide groove 28 via the slide rod 29, driving the brush 293 to rub the filter 27, removing dust and debris, and preventing the filter 27 from becoming clogged and affecting sound production. The elasticity of the tension spring 292 can cause the push-pull plate 291 to return to its original position after sliding.
