Description

Technical Field

[0001] This utility model belongs to the field of road traffic safety technology, specifically relating to an audible and visual alarm device for restricted road sections. Background Technology

[0002] Currently, existing traffic management devices are functionally limited, only able to execute single logical signals and unable to adjust signal frequencies according to the on-site environment. For example, in some restricted areas, using only static signs such as "No Entry" is easily overlooked at night, in inclement weather, or when drivers are negligent, resulting in limited warning effectiveness. Installing ordinary flashing lights, such as simple rotating strobe lights, is functionally limited, lacks specificity, easily causes light pollution, and cannot distinguish between time warnings and other alarms; prolonged use can lead to driver desensitization. Manual monitoring is costly, inefficient, and poses safety hazards.

[0003] Therefore, it is necessary to research and develop an audible and visual alarm device for restricted road sections to solve the above problems. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an audible and visual alarm device for restricted road sections. By installing a power control module and an audible and visual alarm inside the alarm box, visual and auditory warning signals are integrated. The front opening of the alarm box contains a flat viewing panel that is easy to disassemble and install, as well as a soft interception component. This allows both signals to be effectively transmitted while the power control module and the audible and visual alarm are not easily damaged, thus overcoming the shortcomings of the prior art.

[0005] The present invention provides the following technical solution: A sound and light alarm device for restricted road sections includes a support frame and an alarm box. The alarm box is rotatably connected to the top of the support frame. The front of the alarm box is open. A slot is provided on the side of the alarm box near the front opening. A flat viewing plate is embedded in the slot. At least two positioning holes are provided on the flat viewing plate. At least two locking bolts are threaded on the side of the front of the alarm box. The multiple locking bolts correspond one-to-one with the multiple positioning holes, and the ends of the locking bolts extend into the slot. The height of the inner cavity of the alarm box is greater than the height of the planar transparent panel. A sound transmission channel is reserved between the bottom end of the planar transparent panel embedded in the slot and the inner bottom wall of the alarm box, and a soft interception component is installed in the sound transmission channel. The alarm box is equipped with a power control module, and the connection terminal of the power control module is electrically connected to an audible and visual alarm. The installation height of the audible and visual alarm corresponds to the center point of the planar viewing panel.

[0006] Preferably, the soft interception component includes an elastic metal mesh, with an upper crossbeam and a lower crossbeam respectively located at the top and bottom of the sound propagation channel. The upper and lower crossbeams are distributed in parallel, and tightening bolts pass through both sides of the upper and lower crossbeams to support them inside the alarm box. The top and bottom of the elastic metal mesh are fixed to the upper and lower crossbeams respectively by screws. A track groove is provided at the top of the upper crossbeam to fit into the bottom of the planar viewing plate.

[0007] Preferably, the width of the upper crossbeam is smaller than the width of the lower crossbeam, so that the elastic metal mesh is arranged at an angle inside the sound transmission channel.

[0008] Preferably, the upper crossbeam, the lower crossbeam, and the elastic metal mesh are of equal length, and both ends of the upper crossbeam, the lower crossbeam, and the elastic metal mesh are seamlessly fitted to the inner wall of the alarm box.

[0009] Preferably, the planar transparent panel is made of transparent plastic or transparent glass.

[0010] Preferably, the planar perspective plate slides into the slot, and the outer diameter of the planar perspective plate matches the inner diameter of the slot.

[0011] Preferably, the support frame is configured as a telescopic frame structure, and the top of the support frame is connected to the sleeve at the bottom axis of the alarm box via a bearing.

[0012] Preferably, the bottom end of the support frame is fixedly connected to a base plate, and a plurality of ground nails are provided on the base plate.

[0013] Preferably, it also includes a swaying mechanism, which includes a drive motor fixed inside the alarm box. The output shaft of the drive motor passes through the bottom wall of the alarm box and is connected to a turntable. An eccentric shaft is installed on one side of the bottom of the turntable. A vertical shaft is installed at the bottom of the alarm box, and a drive component is rotatably connected to the bottom of the vertical shaft. The drive component has a strip groove on its surface. An arc plate is provided at the end of the drive component away from the strip groove, and a rack is provided on the outer side of the arc plate along the arc trajectory. A ring gear is interference-fitted on the outer side of the support frame, and the ring gear meshes with the rack for transmission. The bottom end of the eccentric shaft is in sliding fit with the strip groove.

[0014] Preferably, the power control module includes a battery and a microcontroller. The connection terminal of the microcontroller is equipped with a timer. The battery powers the audible and visual alarm, the drive motor, the microcontroller, and the timer. The timer feeds back a time signal to the microcontroller. When the set restricted period is reached, the microcontroller controls the audible and visual alarm and the drive motor to work.

[0015] Compared with the prior art, this utility model has the following advantages: By installing a power control module and an audible and visual alarm inside the alarm box, visual and auditory warning signals are integrated. The front opening of the alarm box has a flat transparent panel that is easy to disassemble and install, as well as soft interception components. This allows both signals to be effectively transmitted while the power control module and audible and visual alarm are not easily damaged. Combined with the protection of the alarm box, the direction of sound and flashing light propagation is targeted, which to some extent solves the problems of ineffective warnings and light pollution, thereby improving the warning effect and safety.

[0016] By designing the power control module, the timer is synchronized with Beijing time and feeds back the time signal to the microcontroller. Within the restricted area set by the microcontroller, the audible and visual alarm is activated, providing both visual and voice prompts. Outside the preset area, the mains power output is stopped, and the audible and visual alarm stops operating. The device is highly intelligent, requires no manual operation, reduces labor costs, and improves warning efficiency.

[0017] By setting up a swing mechanism, in conjunction with a support frame and an alarm box, the alarm box can be made to swing repeatedly, simulating a head-shaking motion, thereby changing the orientation of the alarm box opening to achieve a warning effect for vehicles coming from different directions, significantly enhancing its functionality and practicality.

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.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can refer to a detachable connection: it can be a mechanical connection; it can also be an indirect connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] like Figure 1-5The device shown is an audible and visual alarm for restricted road sections, comprising a support frame 1 and an alarm box 2. The alarm box 2 is rotatably connected to the top of the support frame 1. The front of the alarm box 2 is open, and a slot 3 is provided on the side of the alarm box 2 near the front opening. A planar viewing plate 4 is embedded in the slot 3. At least two positioning holes 5 are provided on the planar viewing plate 4. At least two locking bolts 6 are threaded on the front side of the alarm box 2. The multiple locking bolts 6 correspond one-to-one with the multiple positioning holes 5, and the ends of the locking bolts 6 extend into the slot 3. The height of the inner cavity of the alarm box 2 is greater than the height of the planar viewing plate 4. A sound transmission channel is reserved between the bottom end of the planar viewing plate 4 embedded in the slot 3 and the inner bottom wall of the alarm box 2. The planar viewing plate 4 is inserted into the slot 3, and the front opening of the alarm box 2 is partially closed. After it is inserted into place, the locking bolt 6 is screwed into the threaded hole until the end of the locking bolt 6 is embedded in the corresponding positioning hole 5, and the planar viewing plate 4 is effectively fixed. Through the planar viewing plate 4, the electrical components inside the alarm box 2, such as the sound and light alarm 9, can be observed. The high-brightness LED flashing light contained therein can effectively warn passing people and vehicles.

[0029] A soft interception component 7 is installed within the sound propagation channel. In a preferred embodiment, the soft interception component 7 includes an elastic metal mesh 71. An upper crossbeam 72 and a lower crossbeam 73 are respectively positioned at the top and bottom of the sound propagation channel. The upper and lower crossbeams 72 and 73 are parallel to each other, and both sides of the upper and lower crossbeams 72 and 73 are perforated with tightening bolts 74 for supporting the inner side of the alarm box 2. The top and bottom of the elastic metal mesh 71 are fixed to the upper and lower crossbeams 72 and 73 respectively with screws. A rail groove 75 is provided at the top of the upper crossbeam 72 to fit into the bottom of the planar viewing plate 4. Both the upper and lower crossbeams 72 and 73 are U-shaped. The tightening bolts 74 on both sides penetrate the sidewalls and abut against the inner wall of the alarm box 2. After effective fixing, they can support the planar viewing plate 4, and the planar viewing plate 4 cooperates with the rail groove 75 to improve the stability and airtightness of the planar viewing plate 4. The soft interception component 7 intercepts sound in the sound propagation channel without obstructing air transmission, and can prevent impurities such as insects and birds from entering the alarm box 2, thereby interfering with the warning effect.

[0030] The alarm box 2 contains a power control module 8, which is electrically connected to an audible and visual alarm 9. The installation height of the audible and visual alarm 9 corresponds to the center point of the planar viewing panel 4. The audible and visual alarm 9 is a module with both visual and auditory components. The visual component can be a high-brightness LED strobe light; the auditory component can be a high-pitched speaker, which can emit specific alarm sounds and voice prompts. Its installation position is easily observable.

[0031] Furthermore, in the above design, the width of the upper crossbeam 72 is smaller than the width of the lower crossbeam 73, causing the elastic metal mesh 71 to be arranged at an angle inside the sound transmission channel. The elastic metal mesh 71 is easy to install and connect, and has a certain degree of elastic deformation, preventing damage upon impact, and is also easy to replace.

[0032] Furthermore, in the above scheme, the upper horizontal frame 72, the lower horizontal frame 73, and the elastic metal mesh 71 are of equal length, and the two ends of the upper horizontal frame 72, the lower horizontal frame 73, and the elastic metal mesh 71 are seamlessly attached to the inner wall of the alarm box 2.

[0033] Furthermore, in the above scheme, the planar transparent panel 4 is made of transparent plastic or transparent glass.

[0034] Furthermore, in the above scheme, the planar perspective plate 4 and the slot 3 are slidably fitted together, and the outer diameter of the planar perspective plate 4 matches the inner diameter of the slot 3.

[0035] Furthermore, in the above scheme, the support frame 1 is configured as a telescopic frame structure, and the top of the support frame 1 is connected to the sleeve 10 at the bottom axis of the alarm box 2 via a bearing. This allows the opening orientation and installation height of the alarm box 2 to be adjusted, facilitating warnings of people or vehicles approaching from different directions.

[0036] Furthermore, in the above-described design, a base plate 11 is fixedly connected to the bottom end of the support frame 1, and multiple ground nails 12 are provided on the base plate 11. During installation, the base plate 11 can be fixed by the ground nails 12, thereby improving the stability of the installation of this device.

[0037] The audible and visual alarm device also includes a head-shaking mechanism 13. The head-shaking mechanism 13 includes a drive motor 131 fixed inside the alarm box 2. The output shaft of the drive motor 131 passes through the bottom wall of the alarm box 2 and is connected to a turntable 132. An eccentric shaft 133 is installed on one side of the bottom of the turntable 132. A vertical shaft 134 is installed at the bottom of the alarm box 2, and a drive component 135 is rotatably connected to the bottom of the vertical shaft 134. A strip groove 1351 is opened on the surface of the drive component 135. An arc plate 1352 is provided at the end of the drive component 135 away from the strip groove 1351. A rack 1353 distributed along the arc trajectory line is provided on the outer side of the arc plate 1352. A ring gear 1354 is interference-fitted on the outer side of the support frame 1, and the ring gear 1354 meshes with the rack 1353 for transmission. The bottom of the eccentric shaft 133 is slidably engaged with the strip groove 1351. The oscillating mechanism 13 can work synchronously with the audible and visual alarm 9. That is, when the audible and visual alarm 9 is activated, the oscillating mechanism 13 causes the alarm box 2 to oscillate periodically. Specifically, the output shaft of the drive motor 131 drives the turntable 132, causing the eccentric shaft 133 to rotate around the axis of the turntable 132. The bottom end of the eccentric shaft 133 slides in the strip groove 1351, and the drive member 135 rotates on the vertical shaft 134. Under the pull of the eccentric shaft 133, the arc plate 1352 at the end of the drive member 135 oscillates back and forth in a reciprocating manner. The rack 1353 on its outer side can mesh with the ring gear 1354, so that the sleeve 10 and the alarm box 2 on its top can move on the support frame 1, thereby achieving the warning effect in different directions.

[0038] like Figure 6 As shown, the power control module 8 includes a battery 14 and a microcontroller 15. The connection terminal of the microcontroller 15 is equipped with a timer 16. The battery 14 supplies power to the audible and visual alarm 9, the drive motor 131, the microcontroller 15, and the timer 16. The timer 16 feeds back a time signal to the microcontroller 15. When the set restricted period is reached, the microcontroller 15 controls the audible and visual alarm 9 and the drive motor 131 to work.

[0039] Specifically, the battery 14 is charged by an external power source. For example, the device can be installed in the middle of the street light distribution box for independent power supply; or a photovoltaic panel can be installed on the outside of the device to use photovoltaic power generation technology to charge the battery 14.

[0040] In use, this device is installed on the road section requiring control. The timer 16 is synchronized with Beijing time and sends a time signal back to the microcontroller 15. The microcontroller 15 can set restricted zones for the designated road sections. For example, the first operating zone can be set to AM 6:30-8:30; the second operating zone to PM 4:30-6:00. AC 220V mains power is supplied to the audible and visual alarm 9, which immediately activates, displaying a visual alarm and voice prompt: "Restricted area, vehicles prohibited from passing." Outside the preset zones, the mains power output stops, and the audible and visual alarm 9 ceases operation.

[0041] When the audible and visual alarm 9 is working, both audible and visual warning signals can be effectively transmitted, and it also protects the internal electrical components of the alarm box 2.

[0042] The above are only specific embodiments of this utility model, but the structural features of this utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of this utility model are covered by the patent scope of this utility model.
