[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0020] This invention provides a height limiting device for a 10kV power grid, such as... Figure 1 As shown, the device includes a main body 1 and a fixing assembly 2 for fixing the main body 1 to a power grid frame; the main body 1 and the fixing assembly 2 are detachably connected; the fixing assembly 2 is equipped with a monitoring module 3 for monitoring whether there are personnel or obstacles on or near the height line and a ranging module 4 for detecting the distance of personnel or obstacles on the height line; the monitoring module 3 and the ranging module 4 are respectively located on the lower side of the main body 1; the main body 1 is equipped with a central control module for receiving data transmitted by the monitoring module 3 and the ranging module 4 and an alarm module 5 for issuing audible and visual alarms and dialing alarm telephones; the central control module is communicatively connected to the monitoring module 3 and the ranging module 4 respectively; the alarm module 5 is electrically connected to the central control module.
[0021] Specifically, in practical applications, the fixed component 2 is installed on the power grid iron frame, and the fixed component 2 serves as the reference frame for the entire device. The device body 1, the ranging module 4, and the monitoring module 3 are installed on the fixed component 2 to realize the installation of the entire device. In this process, it can effectively avoid the fact that the traditional height restriction device relies entirely on the iron frame for installation, which is cumbersome, time-consuming, and labor-intensive for disassembly and maintenance, and further improves the adaptability of the scenario. After installation, during operation, the central control module inside the device body 1 processes the information transmitted by the ranging module 4 and the monitoring module 3. After processing, it determines whether a warning is required and whether it is at various warning levels. The alarm module 5 is then used to issue audible and visual alarms and remote alarms to notify maintenance personnel, thus playing a warning and alarm role and further protecting personal and property safety.
[0022] Further, the fixing component 2 includes: a fixing plate 21, a first support column 22 and a second support column 23; the fixing plate 21 is disposed on the power grid frame; the first support column 22 and the second support column 23 are detachably connected to the fixing plate 21 to form a fixing frame for installing the device body 1; the device body 1 is detachably connected to the first support column 22 and the second support column 23.
[0023] In Embodiment 1, by installing the fixing plate 21 on the power grid frame and then installing the first support column 22 and the second support column 23 on the fixing plate 21, an overall installation frame is formed so that the various modules can be installed later.
[0024] Furthermore, it also includes at least one reinforcing member 6 for fixing the positions of the first support column 22 and the second support column 23; one end of the fixing member is sleeved on the first support column 22, and the other end is sleeved on the second support column 23; a plurality of snap-fit grooves 24 are respectively provided at equal intervals on the first support column 22 and the second support column 23; a fixing member is provided inside the reinforcing member 6; one end of the fixing member can be snapped with any snap-fit groove 24 on the first support column 22, and the other end can be snapped with any snap-fit groove 24 on the second support column 23; an adjusting member 61 for adjusting the length of the fixing member is rotatably provided on the reinforcing member 6; the adjusting member 61 is connected to the fixing member in a transmission manner.
[0025] In Embodiment 2, the relative positions of the first support column 22 and the second support column 23 are fixed by the reinforcement member 6 to prevent positional displacement and subsequent detachment under adverse weather conditions. The length of the fixing member is adjusted by the adjusting member 61. When the reinforcement member 6 is adjusted to a suitable position, the length of the fixing member is adjusted by the adjusting member 61 so that it is engaged in the engaging groove 24 on the first support column 22 and the second support column 23. This achieves relative structural fixation between the reinforcement member 6 and the first support column 22 and the second support column 23, thereby strengthening the structure and further improving scene adaptability.
[0026] Optionally, the fastener is a telescopic rod, the length of which can be adjusted by an adjustment key to achieve a snap-fit fixation effect.
[0027] Furthermore, the monitoring module 3 includes: a surveillance camera for capturing images and an infrared monitor for monitoring whether there are obstacles or personnel on the height restriction line; the surveillance camera and the infrared monitor are detachably connected to the fixed component 2; the surveillance camera and the infrared monitor are communicatively connected to the central control module.
[0028] Furthermore, the ranging module 4 includes an infrared rangefinder; the infrared rangefinder is detachably connected to the fixed component 2; and the infrared rangefinder is communicatively connected to the central control module.
[0029] In Embodiment 3, an infrared monitor is used to identify the area near the height restriction line. When an object is detected approaching, a signal is sent to the central control module. The central control module determines whether it is a person approaching based on the monitoring camera. If a person is approaching, a signal is transmitted to the alarm module 5 to emit an audible and visual signal to make the approaching person move away as soon as possible. If the person remains in the approaching state for a long time, the alarm module 5 remotely alarms and notifies the maintenance personnel to ensure safety. When the central control module determines that no personnel are approaching based on the monitoring camera, it uses an infrared rangefinder to calculate the distance to the obstacle and triggers different alarm levels according to the approaching distance. The alarm module 5 remotely alarms and notifies the maintenance personnel to ensure safety.
[0030] Furthermore, the device body 1 includes: a dustproof cabinet 11 and a mounting frame 12; the mounting frame 12 is detachably connected to the fixing component 2; the dustproof cabinet 11 is detachably connected to the mounting frame 12; the central control module and the alarm module 5 are respectively disposed in the dustproof cabinet 11.
[0031] Specifically, the dustproof cabinet 11 can effectively prevent dust, rainwater and other substances from entering and damaging electronic components, further improving scene adaptability.
[0032] Furthermore, the alarm module 5 includes: an audible and visual alarm component 51 and a wireless communication component for alarming; the audible and visual alarm component 51 is detachably connected to the dustproof cabinet 11 and is located outside the dustproof cabinet 11; the wireless communication component and the audible and visual alarm component 51 are electrically connected to the central control module respectively.
[0033] Furthermore, the reinforcement member 6 is also provided with an installation part 7 for connecting to the power grid frame; the installation part 7 is detachably connected to the reinforcement member 6.
[0034] In other embodiments, the fastener can be fixed to a nearby iron frame by the mounting component 7, thereby achieving a further reinforcement effect.
[0035] This invention provides a height restriction device for a 10kV power grid. Through the installation of the fixing component 2, the installation of the height restriction device becomes more modular. Compared to traditional welding or bolt fixing, this effectively reduces disassembly and maintenance time, improves operation and maintenance efficiency and installation convenience, and further enhances scenario adaptability. The monitoring module 3 and the ranging module 4 work together to achieve graded alarms and dynamic monitoring. Even in severe weather, real-time monitoring of the environmental conditions near the height restriction line can be achieved, providing effective protection. After triggering a graded alarm, the device provides audible and visual alarms, remote alarm calls, and notification of maintenance personnel in the area, demonstrating high scenario adaptability.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention.
