Description

Technical Field

[0001] This utility model relates to the field of warning equipment technology, specifically a high-intensity flashing sound and light electronic warning device. Background Technology

[0002] In various complex scenarios of modern society, such as road construction, airport runways, fire rescue sites, and high-risk industrial operation areas, high-intensity flashing light and sound-based electronic warning devices play an indispensable role. These devices can quickly attract people's attention and transmit danger signals through high-frequency flashing light and high-decibel warning sounds. With the rapid development of urban construction, transportation, and industrial production, the mobility and density of people and equipment have increased significantly, and potential safety risks have also increased. These warning devices can quickly transmit potential danger information to people in the surrounding area through a combination of sound and light in adverse weather, at night, or in environments with obstructed visibility, reminding people to take timely avoidance measures and effectively preventing safety accidents. They are an important line of defense for protecting people's lives and property.

[0003] Traditional high-intensity flashing sound and light warning devices have many shortcomings in practical applications. On the one hand, their height and angle are often fixed after installation, making it difficult to adjust flexibly according to the needs of different scenarios. This results in limited coverage of the warning signal, and in complex terrain or environments with tall obstacles, the warning information cannot be effectively delivered to the target population. On the other hand, traditional devices mostly use a single power transmission and control method, which suffers from low power transmission efficiency and poor control precision. This makes the response speed of the warning device slow and the stability of the sound and light signal insufficient, making it difficult to meet the requirements of timely and accurate warnings in emergency situations. These defects not only reduce the effectiveness of the warning device, but may also delay the opportunity for personnel to take refuge in critical moments due to the inability to issue timely and effective warnings, causing irreparable losses. Therefore, we propose a high-intensity flashing sound and light electronic warning device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a high-intensity flashing sound and light electronic warning device, which solves the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a high-intensity flashing sound and light electronic warning device, including a base;

[0006] A fixing column is fixedly connected to the top of the base, and parallel limiting strips are provided on both sides of the outer wall of the fixing column;

[0007] The limiting strip is perpendicular to the horizontal plane;

[0008] A sleeve is fitted on the top of the fixed column, and the outer wall of one side of the limiting strip is in sliding fit with both sides of the inner wall of the sleeve.

[0009] The sleeve has a transmission cavity at one end of its inner wall, and a bevel gear is movably connected to the bottom of the inner wall of the transmission cavity;

[0010] A lead screw is fixedly connected to the bottom of the bevel gear, and the bottom of the lead screw extends to one end of the inner wall of the sleeve;

[0011] The outer wall of one end of the lead screw is threaded to the inner wall of the fixed column.

[0012] Preferably, a stepper motor is fixedly connected to the top of the inner wall of the sleeve;

[0013] The bottom rotating shaft of the stepper motor is fixedly connected to a second bevel gear;

[0014] A third bevel gear is movably connected to both sides of the inner wall of the transmission cavity.

[0015] Preferably, the bottom of the second bevel gear is meshed with the third bevel gear, and the top of the bevel gear is meshed with the third bevel gear.

[0016] Preferably, a fixing box is fixedly connected to the top of the sleeve, and a worm gear is movably connected to the bottom of the inner wall of the fixing box;

[0017] A worm gear is movably connected to one end of the bottom of the inner wall of the fixed box;

[0018] A second stepper motor is fixedly connected to the bottom of the inner wall of the fixed box near the worm gear end, and the rotating shaft of the second stepper motor is fixedly connected to a connecting shaft on one side of the worm gear.

[0019] Preferably, a mounting rod is fixedly connected to the top of the worm gear, and the top of the mounting rod extends to the top of the fixing box;

[0020] The mounting rod has a connecting seat on one end of its outer wall, and the mounting rod and the connecting seat are threadedly connected by a bolt.

[0021] Preferably, a strobe light is movably connected to the outer wall of the end of the connecting seat away from the mounting rod;

[0022] Parallel alarm loudspeakers are fixedly connected to both sides of the bottom of the strobe light.

[0023] Preferably, the base has four mounting holes that are equidistantly distributed in a rectangular shape on its top.

[0024] Compared with the prior art, this utility model provides a high-intensity flashing sound and light electronic warning device, which has the following beneficial effects:

[0025] 1. This high-intensity flashing sound and light electronic warning device, compared to traditional warning devices with a fixed height after installation, which are easily blocked in complex terrain or environments with tall obstacles, making it difficult to effectively cover the target area, achieves a different effect. This device uses the linkage of components such as a stepper motor, a second bevel gear, a third bevel gear, a bevel gear, and a lead screw to enable the sleeve to slide up and down along the fixed column. When encountering road construction areas with large construction vehicles or tall buildings next to airport runways, the height of the sleeve can be precisely adjusted by controlling the stepper motor, raising the position of the flashing light and alarm loudspeaker to ensure that the warning signal can overcome obstacles and reach a farther and higher range. This effectively solves the problem of blind spots caused by the fixed height of traditional devices and greatly improves the applicability of the device in complex environments.

[0026] 2. This high-intensity flashing sound and light electronic warning device, compared to traditional warning devices with fixed illumination and sound angles that cannot be flexibly adjusted according to actual needs, and which have obvious blind spots in some scenarios requiring multi-directional warnings, utilizes a second stepper motor to drive a worm gear, which in turn drives the mounting rod to rotate. This allows the strobe light and alarm loudspeaker on the connecting base to be adjusted horizontally. In fire rescue scenes, the rescue area may have multiple potential danger directions. By precisely controlling the second stepper motor, the sound and light warning signals can be adjusted to different directions, providing all-round coverage of the rescue scene and avoiding situations where some areas are not warned due to fixed angles. Compared to traditional devices, it can more effectively transmit danger signals to people in all directions, significantly expanding the warning range.

[0027] 3. This high-intensity flashing sound and light electronic warning device, compared to traditional warning devices that use a single power transmission and control method, suffers from low power transmission efficiency and poor control precision, resulting in insufficient stability of the sound and light signals and inability to issue timely and accurate warnings in emergencies, utilizes dual stepper motors to control height and angle adjustment respectively. The stepper motors transmit power efficiently to the lead screw through multi-stage bevel gear transmission, achieving stable lifting and lowering of the sleeve; the second stepper motor precisely controls the rotation angle of the mounting rod through worm gear transmission. In the event of a sudden emergency in a high-risk industrial work area, the device can respond quickly. The stepper motors can precisely control the flashing light and alarm loudspeaker to adjust to the appropriate height and angle in a short time, while stably outputting strong light flashes and high-decibel warning sounds. Compared to traditional devices, this significantly improves the timeliness, accuracy, and reliability of warnings, buying valuable time for personnel to avoid danger and reducing the probability of safety accidents.

[0033] 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.

[0034] Please see Figure 1-4 A high-intensity flashing sound and light electronic warning device includes a base 1, which serves as the basic support component of the device, providing stable and reliable support for the entire device and ensuring that the device does not shake or shift during use.

[0035] The base 1 is fixedly connected to the top of the fixed column 2. The outer walls of the fixed column 2 are provided with parallel limiting strips 3. The fixed column 2 is used to support the sleeve 4 and other components. The limiting strips 3 are perpendicular to the horizontal plane and slide with the inner walls of the sleeve 4 to provide precise guidance for the up and down sliding of the sleeve 4, prevent the sleeve 4 from deviating or tilting during the lifting process, and ensure that the sleeve 4 can move smoothly and vertically.

[0036] The limiting strip 3 is perpendicular to the horizontal plane. The vertically set limiting strip 3, together with the inner wall structure of the sleeve 4, further strengthens the constraint on the movement direction of the sleeve 4, ensuring that the sleeve 4 slides stably up and down on the fixed column 2, and maintaining the stability and movement accuracy of the overall structure of the device.

[0037] A sleeve 4 is fitted on the top of the fixed column 2. The outer wall of one side of the limiting strip 3 is in sliding fit with the inner walls of the sleeve 4. The sleeve 4 can slide up and down along the fixed column 2 under the guidance of the limiting strip 3. By changing the height of the sleeve 4, the height of the strobe light 18 and the alarm loudspeaker 19 installed on its top can be adjusted to meet the warning needs in different scenarios.

[0038] One end of the inner wall of the sleeve 4 is provided with a transmission cavity 5. A bevel gear 6 is movably connected to the bottom of the inner wall of the transmission cavity 5. The transmission cavity 5 provides a closed installation space for the transmission components such as the bevel gear 6, protecting the internal transmission components from interference from external debris. At the same time, it makes the layout of the transmission components compact and reasonable, ensuring the stability and reliability of power transmission.

[0039] A lead screw 7 is fixedly connected to the bottom of the bevel gear 6. The bottom of the lead screw 7 extends to one end of the inner wall of the sleeve 4. By fixing the bevel gear 6 and the lead screw 7, the rotational motion of the bevel gear 6 can be converted into the linear motion of the lead screw 7, providing a power conversion basis for the lifting and lowering of the sleeve 4 and realizing an effective change in the transmission form.

[0040] One end of the lead screw 7 is threaded to the inner end of the fixed column 2. Based on the principle of threaded transmission, when the lead screw 7 rotates, it can drive the sleeve 4 to move up and down along the fixed column 2. By precisely controlling the rotation direction and number of turns of the lead screw 7, the height of the sleeve 4 can be precisely adjusted to meet the warning requirements at different heights.

[0041] A stepper motor 8 is fixedly connected to the top of the inner wall of the sleeve 4. As the core power component, the stepper motor 8 can accurately output rotational power according to the preset program, providing a stable and controllable power source for the transmission system of the entire device, and ensuring that each component of the device can operate accurately.

[0042] A second bevel gear 9 is fixedly connected to the bottom rotating shaft of the stepper motor 8. The second bevel gear 9 is connected to the rotating shaft of the stepper motor 8, which can transmit the rotational power output by the stepper motor 8 to other bevel gear components in the transmission cavity 5, so as to realize the efficient transmission of power from the motor to the transmission components and ensure the continuity of power transmission.

[0043] The inner walls of the transmission cavity 5 are movably connected to the two sides of the third bevel gear 10. The third bevel gear 10 changes the direction of power transmission through meshing with the second bevel gear 9 and the bevel gear 6, so that the power can be smoothly transmitted from the horizontal direction to the vertical direction, which meets the power direction requirements for the rotation of the lead screw 7 and realizes the rational distribution of power.

[0044] The bottom of the second bevel gear 9 is meshed with the third bevel gear 10, and the top of the bevel gear 6 is meshed with the third bevel gear 10. This allows the power of the stepper motor 8 to be transmitted and amplified step by step, effectively driving the bevel gear 6 to rotate, which in turn drives the lead screw 7 to operate, achieving efficient power transmission and enhancement, and ensuring the stability of the sleeve 4 lifting and lowering.

[0045] The top of the sleeve 4 is fixedly connected to a fixed box 11, and the bottom of the inner wall of the fixed box 11 is movably connected to a worm gear 12. The fixed box 11 provides a protective shell for the transmission components such as the worm gear 12, preventing external factors such as dust and moisture from affecting the normal operation of the components. At the same time, it provides a stable frame for the installation of the components, ensuring that the worm gear 12 and other components can be reliably installed and work stably.

[0046] A worm gear 13 is movably connected to one end of the bottom of the inner wall of the fixed box 11. The worm gear 13 and the worm wheel 12 cooperate to form a worm gear transmission mechanism, which can reduce the speed, increase the torque, and change the direction of motion, providing suitable power parameters for the rotation of the mounting rod 15, so that the mounting rod 15 can rotate smoothly and accurately.

[0047] A second stepper motor 14 is fixedly connected to the bottom of the inner wall of the fixing box 11 near the end of the worm gear 13. The rotating shaft of the second stepper motor 14 is fixedly connected to the connecting shaft on one side of the worm gear 13. The second stepper motor 14 serves as a power source, converting electrical energy into rotational power and precisely transmitting it to the worm gear 13 to drive the worm gear transmission mechanism to operate, thereby achieving precise control of the rotation of the mounting rod 15 and ensuring the accuracy of the warning direction adjustment.

[0048] A mounting rod 15 is fixedly connected to the top of the worm gear 12. The top of the mounting rod 15 extends to the top of the fixed box 11. When the worm gear 12 rotates under the drive of the worm 13, it can drive the mounting rod 15 to rotate synchronously, thereby realizing the horizontal adjustment of the strobe light 18 and the alarm loudspeaker 19 mounted on the mounting rod 15, so that the sound and light warning signal can cover a wider area.

[0049] A connecting seat 16 is provided on the outer wall of one end of the mounting rod 15. A bolt 17 is threadedly connected between the mounting rod 15 and the connecting seat 16. The threaded connection allows the connecting seat 16 to be firmly installed on the mounting rod 15. By turning the bolt 17, the angle of the connecting seat 16 can be finely adjusted, so as to flexibly adjust the angle of the strobe light 18 and the alarm loudspeaker 19 to adapt to different warning scenarios.

[0050] A strobe light 18 is movably connected to the outer wall of the end of the connector 16 away from the mounting rod 15. The movable connection design allows the strobe light 18 to adjust the illumination angle within a certain range. It can project the strong light strobe signal to different directions according to actual needs, enhance the warning effect, and improve the coverage and effectiveness of the warning signal.

[0051] The bottom two sides of the strobe light 18 are fixedly connected with parallel alarm loudspeakers 19. The alarm loudspeakers 19 are fixedly connected to the strobe light 18 and can synchronously change the sound direction as the angle of the strobe light 18 is adjusted, so that the sound and light signals can work together to warn in the same direction. Through the dual stimulation of sound and light, the transmission efficiency and warning effect of the warning information are improved.

[0052] The top of the base 1 has four rectangularly spaced mounting holes 20.

[0053] Working principle: First, the device can be fixed in the target position through four rectangularly spaced mounting holes 20 on the top of the base 1, providing a stable installation foundation for the entire device. The fixing column 2, which is fixedly connected to the top of the base 1, has parallel limiting strips 3 perpendicular to the horizontal plane on both sides of its outer wall. This structural design allows the fixing column 2, supported by the base 1, to provide precise guiding support for the subsequent up and down sliding of the sleeve 4, achieving the effect of stable installation of the device and support of the foundation structure. The sleeve 4, which is fitted on the top of the fixing column 2, has a transmission cavity 5 on one side of its inner wall. The bottom of the bevel gear 6 in the transmission cavity 5 is fixedly connected to the lead screw 7, and the bottom of the lead screw 7 extends to one end of the inner wall of the sleeve 4. At the same time, the outer wall of one end of the lead screw 7 forms a threaded connection with one end of the inner wall of the fixing column 2. When the transmission structure inside the transmission cavity 5 drives the bevel gear 6 to rotate, the rotation of the bevel gear 6 will drive the lead screw 7 to rotate synchronously. Since the lead screw 7 is threadedly connected to the inner wall of the fixed column 2, under the principle of threaded transmission, the rotation of the lead screw 7 will be converted into the up-and-down sliding of the sleeve 4 along the outer wall of the fixed column 2. The sliding cooperation between the limit strip 3 and the two sides of the inner wall of the sleeve 4 ensures the smoothness of the lifting process of the sleeve 4, and achieves the effect of adjusting the warning height of the sleeve 4 by lifting it up and down along the fixed column 2 through the lead screw transmission. The stepper motor 8 is fixedly connected to the top of the inner wall of the sleeve 4, and its bottom rotating shaft is fixedly connected to the second bevel gear 9. The third bevel gear 10 is movably connected to the two sides of the inner wall of the transmission cavity 5, and meshes with the bottom of the second bevel gear 9 and the top of the bevel gear 6 respectively. When the stepper motor 8 starts, its rotating shaft drives the second bevel gear 9 to rotate. The second bevel gear 9 drives the third bevel gear 10 to rotate through meshing transmission. The third bevel gear 10 then drives the bevel gear 6 to rotate through meshing transmission, thereby transmitting the rotational power of the stepper motor 8 to the bevel gear 6 in sequence, thus realizing the rotation of the lead screw 7. Finally, the stepper motor 8 drives the bevel gear set to control the lifting and lowering of the sleeve 4. Inside the fixed box 11 fixedly connected to the top of the sleeve 4, the worm gear 12 movably connected to the bottom of the inner wall and the worm 13 movably connected to one end form a worm gear transmission pair. The second stepper motor 14 is fixedly connected to the bottom of the inner wall of the fixed box 11 near the end of the worm 13, and its rotating shaft is fixedly connected to the connecting shaft on one side of the worm 13. When the second stepper motor 14 starts, its rotating shaft drives the worm gear 13 to rotate. The worm gear 13 drives the worm wheel 12 to rotate through the worm wheel transmission principle. The mounting rod 15, which is fixedly connected to the top of the worm wheel 12, will rotate synchronously with the rotation of the worm wheel 12. This achieves the effect of the second stepper motor 14 driving the worm wheel transmission to drive the mounting rod 15 to rotate and adjust the warning direction. The top of the mounting rod 15 extends to the top of the fixed box 11. One end of its outer wall is provided with a connecting seat 16, and the mounting rod 15 and the connecting seat 16 are threadedly connected by bolts 17.This mechanical connection method allows the connecting seat 16 to be securely mounted on the mounting rod 15. Simultaneously, by adjusting the tightness of the bolts 17, the angle of the connecting seat 16 relative to the mounting rod 15 can be finely adjusted, achieving a secure connection between the mounting rod 15 and the connecting seat 16 while allowing for angle adjustment. The outer wall of the end of the connecting seat 16 furthest from the mounting rod 15 is movably connected to the strobe light 18, and parallel alarm loudspeakers 19 are fixedly connected to both sides of the bottom of the strobe light 18. The connecting seat 16 provides a mounting platform for the strobe light 18 and the alarm loudspeakers 19. The movable connection allows the strobe light 18 to adjust its illumination angle within a certain range, while the alarm loudspeakers 19, fixed to both sides of the bottom of the strobe light 18, can synchronously adjust their sound direction as the position of the strobe light 18 changes. This achieves the effect of the sound and light components being mounted on the connecting seat and able to coordinately adjust the warning angle. When the device is working, the stepper motor 8 and the second stepper motor 14 can be started separately or run synchronously according to control commands. Stepper motor 8 drives sleeve 4 to rise and fall via bevel gear set transmission, adjusting the height of strobe light 18 and alarm loudspeaker 19; second stepper motor 14 drives mounting rod 15 to rotate via worm gear transmission, adjusting the horizontal direction of strobe light 18 and alarm loudspeaker 19; at the same time, strobe light 18 emits a strong light strobe signal, and alarm loudspeaker 19 emits a warning sound. All structures work together through the above linkage method to achieve the comprehensive effect of the strong light strobe sound and light warning device being adjustable in height and direction and emitting sound and light warning signals synchronously, thereby achieving a wider and more effective warning effect in different scenarios.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
