Description

Technical Field

[0001] This invention relates to the field of iron tower technology, and in particular to an iron tower foot warning device and an iron tower. Background Technology

[0002] High-voltage overhead transmission lines commonly use exposed conductors. When large-scale mechanical construction work is carried out near these lines, if the machinery fails to maintain a sufficient safe distance from the live conductors, it can easily lead to electrical discharge accidents, which can cause power grid outages, equipment damage, and even personal injury. Therefore, installing warning devices at the base of the towers and in the surrounding area to remind workers and pedestrians to maintain a safe distance is an important measure for power safety protection.

[0003] Existing tower warning devices mostly adopt a freestanding structure, such as the solar-powered LED electronic warning sign with announcement number CN206480341U. This sign consists of a solar panel, a freestanding sign, LED warning lights, a column, a base, and an infrared alarm. It can trigger an alarm via infrared sensing when someone approaches and can operate long-term using solar power. The device detects approaching people through a sensor port, triggering the LED warning lights to illuminate, thus serving as a reminder. It is suitable for placement on the ground next to the tower.

[0004] However, these warning devices are mostly floor-standing structures, requiring considerable ground space, making installation and transportation inconvenient. Furthermore, most only offer light warnings, lacking audible alarms, thus limiting their effectiveness. In addition, their relatively complex structure makes them unsuitable for placement in the confined spaces at the base of towers, failing to meet the needs of tower areas for small, easy-to-install, and combined audible and visual warnings. Summary of the Invention

[0005] In order to address the technical deficiencies mentioned in the background section, the present invention aims to provide a tower foot warning device and a tower to solve the aforementioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A warning device for the base of a steel tower includes a warning plate and a warning device fixed on the warning plate. The warning device includes a housing, a lampshade, a solar panel, a battery, an alarm, a biosensor, and a circuit board. The lampshade is located on the left and right sides of the housing; The biosensor is located inside the lampshade; The solar panel is disposed on the outer surface of the casing; The battery, alarm, and circuit board are all housed within the housing; The circuit board is equipped with a light source facing the lampshade; The battery, alarm, light source, and biosensor are all electrically connected to the circuit board. The biosensor is used to detect the approach of a living being and trigger the alarm to emit an audible and visual alarm.

[0007] Specifically, the housing includes a fixed base and a front cover detachably connected to the front of the fixed base; The left and right sides of the front cover extend outward to form extension plates, and the lampshade is fixed to the extension plates.

[0008] Specifically, the front cover has light-transmitting holes on both the left and right sides, and the lamp cover has light-transmitting notches corresponding to the light-transmitting holes.

[0009] Specifically, the front end of the front cover has an inclined surface, and a groove is formed on the inclined surface, into which the solar panel is embedded.

[0010] Specifically, the inner surface of the lampshade is provided with several protruding ridges arranged along its length to scatter the light emitted by the light source.

[0011] Specifically, the warning board includes a right-angled plate body and a fixing assembly; The right-angle plate body is provided with a stepped groove extending laterally; The fixing component includes a screw, an L-shaped pressure block, and a nut. The head of the screw is inserted into the stepped groove and can slide along the stepped groove to adjust its position. The screw shaft passes through the L-shaped pressure block and is threadedly connected to the nut. A clamping gap is formed between the L-shaped pressure block and the right-angle plate body.

[0012] Specifically, the right-angle plate body has a groove located at the front end of the stepped groove; The warning board also includes a cover plate and a right-angle panel. The cover plate is embedded in the groove and snapped together with the right-angle panel body. The right-angle panel covers the end face of the cover plate. The right-angled panel has a text warning area on its surface, and the text warning area has a reflective text coating.

[0013] Specifically, the rear end of the housing is provided with a hook, which is hung on the top of the right-angle plate body.

[0014] Specifically, the hook includes three rows of hooks arranged side by side, with adjacent hooks fixedly connected by a connecting plate.

[0015] A type of iron tower, comprising: Iron tower scaffolding; The tower foot warning device is fixed on the tower foot frame.

[0016] Beneficial effects: This application achieves automatic audible and visual warnings for the tower scaffolding area by setting up a right-angled warning board and installing a warning device on it. Combined with the coordinated operation of biosensors, light sources, and alarms, it can simultaneously emit flashing red lights and voice prompts when personnel approach, effectively preventing accidental entry into dangerous areas. The solar panel is tilted and powered by a battery to ensure long-term stable operation of the device without external power. The shell adopts a split structure for easy assembly and maintenance. The raised ridge design on the inner surface of the lampshade ensures uniform diffusion of warning light and improves the visual warning range. The double-sided warning device eliminates monitoring blind spots, the hook-type installation saves space and enhances wind resistance, and the text warning area is coated with a reflective coating to provide basic warnings even in the event of a power outage, significantly improving the safety of work and passage around the tower.

Detailed Implementation

[0019] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0020] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0022] In this application, unless otherwise expressly specified and limited, the terms “installation,” “connection,” “linking,” “fixing,” etc., shall be interpreted broadly. For example, they may refer to a fixed connection, a detachable connection, or an integral part; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; they may refer to the internal connection of two components or the interaction between two components, unless otherwise expressly limited.

[0023] Please refer to Figure 1This embodiment discloses a steel tower, which includes a tower leg 30 and a tower leg warning device, the tower leg warning device being fixed to the tower leg 30. The tower leg warning device is used to install at the tower leg 30 to provide audible and visual warnings to personnel approaching the tower leg 30, in order to prevent personnel from accidentally entering the high-voltage danger zone.

[0024] Please refer to Figure 2 The tower leg warning device includes a warning plate 10 and a warning device 20 fixed on the warning plate 10. The warning device 20 is the actuator for sound and light warning, and the warning plate 10 serves as the mounting carrier for the warning device 20 and is used to fix the entire device to the tower leg 30.

[0025] Please refer to Figure 2 The two sides of the right-angled panel 14 of the warning board 10 are provided with text warning areas 15. The text warning areas 15 are coated with luminous fluorescent text such as "High Voltage Danger, Do Not Approach" or luminous fluorescent patterns of high voltage symbols. Specifically, long-lasting phosphorescent luminous fluorescent paint can be used as the reflective text coating. After absorbing natural light or artificial light during the day, this paint can continuously emit bright fluorescence at night or in dark environments. Even in extreme power outage situations such as failure of the solar panel 23 of the warning device 20 or depletion of the battery, it can still play a basic visual warning role, providing double protection for safety during night inspections or emergencies.

[0026] Please refer to Figure 8 and Figure 9 The alarm device 20 includes a housing 21, a lampshade 22, a solar panel 23, a battery 24, an alarm 25, a biosensor 26, and a circuit board 27. The lampshade 22 is located on the left and right sides of the housing 21. The biosensor 26 is located inside the lampshade 22. The solar panel 23 is located on the outer surface of the housing 21. The battery 24, the alarm 25, and the circuit board 27 are all located inside the housing 21. The circuit board 27 has a light source 28 facing the lampshade 22. The battery 24, the alarm 25, the light source 28, and the biosensor 26 are all electrically connected to the circuit board 27. The biosensor 26 is used to detect the approach of a human body and trigger the alarm 25 to emit an audible and visual alarm.

[0027] In this embodiment, the alarm 20 achieves fully automatic, non-contact audio-visual warning through the coordinated operation of the aforementioned electrical components. When the biosensor 26 detects a person entering a preset danger zone, or when a mouse or other animal crawls past the alarm 20, the biosensor 26 transmits a sensing signal to the circuit board 27. The circuit board 27 then controls the light source 28 to flash and controls the alarm 25 to issue a voice prompt, thus ensuring the warning effect while avoiding manual supervision. Furthermore, all components are hidden inside the housing 21, providing excellent waterproof and dustproof performance. The solar panel 23 converts light energy into electrical energy and stores it in the battery 24. The battery 24 provides unified power to the alarm 25, biosensor 26, circuit board 27, and light source 28, enabling long-term independent operation without an external power source.

[0028] Please refer to Figure 9 The housing 21 includes a mounting base 211 and a front cover 212 detachably connected to the front of the mounting base 211. The left and right sides of the front cover 212 extend outward to form extension plates 2121, and the lampshade 22 is fixed to the extension plates 2121 by screws. This split housing design not only facilitates assembly and production and reduces mold costs, but also allows for quick repair by simply removing the front cover 212 when the internal circuit or battery malfunctions, greatly reducing the difficulty of later maintenance. The structure of the extension plates 2121 effectively expands the installation space of the lampshade 22, allowing the warning light to be projected over a wider area.

[0029] Please refer to Figure 9 and Figure 10 The front cover 212 has light-transmitting holes 2122 on both the left and right sides, and the lampshade 22 has light-transmitting notches 221 corresponding to the light-transmitting holes 2122. There are two circuit boards 27, and a light source 28 is fixed on the surface of the circuit board 27. The surface of the circuit board 27 faces the light-transmitting hole 2122. The light source 28 is preferably an LED light source, and the lampshade 22 is a red lampshade. At night, when the biosensor 26 detects a person approaching or a mouse crawling past the alarm 20, the light source 28 is powered on and emits a bright light, which forms a clear warning effect through the red lampshade. In addition, it works with the alarm 25 to issue a warning such as "High voltage danger, do not approach". The specific working process is as follows: When the biosensor 26 detects a person approaching or a mouse crawling past the alarm 20, it transmits a trigger signal to the circuit board 27. The circuit board 27 controls the two light sources 28 to flash alternately or synchronously at high frequency. The red light penetrates the red lampshade to create a strong visual impact. At the same time, the alarm 25 plays a pre-recorded warning message. The dual stimulation of sound and light can effectively arouse high alertness in personnel, prompting them to immediately stop approaching and evacuate. Alternatively, the sound can deter mice, greatly improving the level of security at night or in environments with poor visibility. The corresponding setting of the light-transmitting holes 2122 and the light-transmitting notches 221 provides a smooth light output channel for the light from the light source 28, preventing the light from being blocked by the housing.

[0030] Please refer to Figure 9 The front cover 212 has an inclined surface at its front end, and a groove 2123 is formed on the inclined surface. The solar panel 23 is embedded in the groove 2123. The upward tilt of the solar panel 23 conforms to the principles of photophysics, which can maximize the reception of direct sunlight and diffused light, significantly improving the light energy collection efficiency. This ensures that the battery 24 can store sufficient electrical energy during the day to meet the continuous working needs of the alarm 20 at night and in rainy weather. The design of the groove 2123 not only serves to position the solar panel 23, but also prevents rainwater from directly washing away the panel and causing water accumulation, thus extending the service life of the solar panel 23.

[0031] In this embodiment, the biosensor 26 uses an infrared sensor. Infrared sensors are characterized by low cost, low power consumption, and mature and stable technology, and can effectively capture changes in infrared radiation emitted by the human body to determine whether someone is approaching. Of course, in other embodiments, to adapt to more complex and severe weather environments (such as heavy fog, strong light interference, etc.) or occasions requiring a longer detection distance, millimeter-wave radar sensors can also be selected. Millimeter-wave radar sensors have the advantages of strong penetration, good anti-interference ability, and high detection accuracy, and can achieve accurate monitoring of minute movements or long-distance intrusions. The specific sensing method used is not limited to the above-listed options, and can be flexibly selected according to the actual application environment and cost budget.

[0032] Please refer to Figure 2 , Figure 3 The warning board 10 includes a right-angled plate body 11, which has a right-angled plate structure with two plate surfaces. There are two warning devices 20. A hook 29 is provided at the rear end of the housing 21, and the hook 29 is hung on the top of the right-angled plate body 11. The two warning devices 20 are respectively fixed to the two tops of the right-angled plate body 11 via the hook 29. The right-angled plate structure of the warning board 10 allows the two warning devices 20 to simultaneously face two mutually perpendicular directions, effectively expanding the protective field of vision and eliminating blind spots. Regardless of which side a person approaches the tower scaffold 30 from, the biosensor 26 can detect them immediately and trigger the alarm. The dual-sided audible and visual alarm design significantly improves the practicality and reliability of the device in complex terrain or intersections.

[0033] Please refer to Figure 10The inner surface of the lampshade 22 is provided with several protruding ribs 222 arranged along its length to diffuse the light emitted by the light source 28. The wavy or striped structure of the protruding ribs 222 can produce diffuse reflection and refraction of light, breaking the originally potentially glaring point or line light source shape, so that the light is repeatedly reflected inside the red lampshade and diffused softly in all directions, forming a uniform warning light curtain with a wider coverage area. This not only enhances the visibility of the warning effect, but also avoids visual fatigue or glare interference caused by excessive local light.

[0034] Please refer to Figure 3 The hook 29 includes three rows of hook portions 291 arranged side by side, with adjacent hook portions 291 fixedly connected by a connecting plate 292. The three rows of hook portions 291 provide multi-point support, significantly increasing the contact area and friction between the hook 29 and the top of the right-angle plate body 11, effectively preventing the warning device 20 from rotating or slipping while suspended. Simultaneously, the connecting plate 292 connects multiple hook portions 291 into a single unit, further enhancing the overall structural strength of the hook 29, ensuring its stability even when subjected to strong winds or other external impacts. Besides the hook-and-clamp connection method of this embodiment, other fixed connection methods such as screw locking, riveting, or snap-fit ​​can also be used between the warning device 20 and the warning plate 10, which can be flexibly selected according to assembly and maintenance requirements.

[0035] Please refer to Figures 2 to 7The warning board 10 includes a right-angled plate body 11 and a fixing component 12. The right-angled plate body 11 has a stepped groove 111 extending laterally. The fixing component 12 includes a screw 121, an L-shaped pressure block 122, and a nut 123. The head of the screw 121 is inserted into the stepped groove 111 and can slide along the stepped groove 111 to adjust its position. The screw shank of the screw 121 passes through the L-shaped pressure block 122 and is threadedly connected to the nut 123. A clamping gap 17 is formed between the L-shaped pressure block 122 and the right-angled plate body 11. The function of the fixing component 12 is to fix the warning board 10 as a whole to the tower leg 30. The two edges of the right-angled plate body 11 are provided with fixing components 12, which are arranged opposite to each other to cooperate and be clamped on both sides of the right-angle structure of the tower leg 30. The adjustment and installation principle is as follows: During installation, first place the two L-shaped pressure blocks 122 on both sides of the right-angle structure of the tower leg 30, so that the L-shaped pressure blocks 122 and the plate surface of the right-angle plate body 11 together form a clamping gap 17, and the corresponding plate edge of the tower leg 30 is accommodated in the clamping gap 17; since the head of the screw 121 is inserted into the stepped groove 111 and can slide laterally along the stepped groove 111, the installer can adjust the position of the screw 121 and the L-shaped pressure block 122 in advance according to the actual thickness and specifications of the tower leg 30, and then tighten the nut 123 so that the L-shaped pressure block 122 clamps and fixes the tower leg 30 on the right-angle plate body 11. The beneficial effect of this structure is that the position of the screw 121 can be continuously adjusted through the stepped groove 111, thereby adjusting the clamping position of the L-shaped pressure block 122 and the size of the clamping gap 17, so that the warning plate 10 of the same specification can be adapted to the tower brackets 30 of different specifications and thicknesses. It has strong versatility and is easy to install, without the need for separate mold customization for each type of tower.

[0036] In addition, screw 121 is a hexagonal screw. When tightening nut 123, since the head of screw 121 is hexagonal and abuts against the two sides of stepped groove 111, stepped groove 111 can play a role in preventing deflection and limiting the head of screw 121. Therefore, the operator does not need to hold screw 121, but only needs to turn nut 123 to complete the tightening.

[0037] Please refer to Figures 3 to 7The right-angled plate body 11 has a groove 112 located at the front end of the stepped groove 111; the warning plate 10 also includes a cover plate 13 and a right-angled panel 14, as well as three side strips 16 for fixing the right-angled panel 14 to the right-angled plate body 11. The right-angled plate 14 is fixed to the right-angled plate body 11 by rivets passing through the side strips 16. Two of the side strips 16 are strip-shaped, and the middle side strip 16 is a right-angled structure. The cover plate 13 is embedded in the groove 112 and snap-fitted to the right-angled plate body 11. Specifically, a slot 113 is provided in the groove 112 of the right-angled plate body 11, and a buckle 131 is provided on the back of the cover plate 13. The buckle 131 and the slot 113 cooperate to achieve a snap-fit ​​connection, and the right-angled panel 14 covers the end face of the cover plate 13. The beneficial effects of this structure are as follows: Firstly, the cover plate 13 and the right-angle panel 14 successively cover the surface of the right-angle plate body 11, making the surface of the warning plate 10 flat, free of protruding screws and other debris, with a neat appearance and not easy to snag; secondly, the cover plate 13 and the right-angle panel 14 provide shielding protection for the internal fixing components 12 (screws 121, nuts 123, etc.), which has a certain degree of water resistance and can effectively prevent rainwater from corroding the screws 121 and nuts 123, causing them to rust and loosen, thus ensuring the reliability of the connection for long-term outdoor use; in addition, the snap-fit ​​connection between the buckle 131 and the slot 113 can be quickly disassembled and assembled without the aid of tools, which is convenient for later maintenance and replacement, and is more convenient and efficient than traditional screw fixing.

[0038] The above-described embodiments are merely illustrative of several specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
