Description

Technical Field

[0001] This utility model relates to the field of substation monitoring devices, and in particular to a substation operator anti-collision monitoring device based on optical ranging technology. Background Technology

[0002] Substations are key facilities in power systems that transform voltage, receive and distribute electrical energy. The working environment is complex and poses high safety risks. During the daily inspection, maintenance and construction of substations, workers need to move in areas with dense equipment. Due to obstructed vision or operational negligence, they may collide with equipment, causing personal injury. Collision prevention monitoring devices are used to monitor the distance between workers and surrounding obstacles in real time and issue warnings when they approach danger zones to ensure the safety of workers.

[0003] Traditional substation worker collision avoidance monitoring devices consist of ultrasonic sensors, alarm modules, and wearable main units. When in use, workers wear the main unit on their bodies, and the ultrasonic sensors are installed on the outside of the main unit, continuously emitting ultrasonic signals to the surroundings. When the signal encounters an obstacle, it is reflected back to the sensor. The main unit calculates the distance based on the signal propagation time. When the distance is less than a preset threshold, the alarm module issues an audible and visual alarm. However, ultrasonic sensors are susceptible to electromagnetic interference within the substation, which leads to a decrease in ranging accuracy.

[0004] To address the poor anti-interference capabilities of traditional devices, existing technologies use optical ranging technology to replace ultrasonic sensors. This leverages the linear propagation characteristics of laser or infrared signals to improve ranging accuracy and electromagnetic interference resistance. However, in practical applications, the fixed installation angle of the optical sensors and their limited detection range, tailored to specific diameter utility poles, prevent the sensor's illumination range from dynamically adapting to the pole's cross-sectional dimensions. This results in insufficient versatility in diverse substation environments and makes it difficult to reliably monitor collision risks from various utility poles. Therefore, a substation worker collision avoidance monitoring device based on optical ranging technology is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a substation worker collision avoidance monitoring device based on optical ranging technology. It aims to improve the problem that the illumination range of optical sensors in the prior art cannot dynamically adapt to the cross-sectional size of the utility pole, resulting in insufficient versatility of the device in diverse substation environments.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a substation worker anti-collision monitoring device based on optical ranging technology, including a backrest, an installation mechanism provided on the rear side of the backrest, an installation plate fixedly connected to the front side of the backrest, and a monitoring mechanism provided on the top of the installation plate.

[0007] The installation mechanism includes a U-shaped clamping plate, the outer wall of which is fixedly connected to the rear side of the backing plate. A sliding groove is provided at the bottom of the U-shaped clamping plate, and a sliding plate is slidably connected to the inner wall of the U-shaped clamping plate. Side ears are fixedly connected to the left and right sides of the sliding plate. Fixing blocks are fixedly connected to the left and right sides of the rear of the backing plate. Fastening bolts are threaded to the inner walls of the two side ears. Two reinforcing components are provided on the left and right sides of the U-shaped clamping plate, and binding components are provided on the upper and lower sides of the rear of the backing plate.

A screw is threadedly connected to the inner wall of the mounting plate, and a transmission block is threadedly connected to the outer wall of the screw. Slider blocks are fixedly connected to the left and right sides of the outer wall of the monitor.

[0010] As a further description of the above technical solution:

[0011] The reinforcement component includes a reinforcement block, the outer wall of which is fixedly connected to the outer wall of the U-shaped plate, and the inner wall of which is threaded with reinforcement bolts.

[0012] As a further description of the above technical solution:

[0013] The binding component includes two straps, the front ends of which are fixedly connected to the rear side of the back panel. The rear end of the right strap is fixedly connected to a buckle, and the outer wall of the left strap has multiple buckle holes.

[0014] As a further description of the above technical solution:

[0015] The top of the mounting plate is fixedly connected to two side plates, and the outer walls of the two side plates are provided with multiple heat dissipation holes.

[0016] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the U-shaped clamping plate initially engages with the utility pole, and the sliding plate slides along the groove to adjust its position, enabling the device to adapt to utility poles of different diameters and improving its versatility. The fastening bolts pass through the side ears and are threadedly connected to the fixing block, so that the sliding plate is firmly locked to prevent it from sliding during use, ensuring the stability of the device installation. This allows the backing plate and the entire device to be stably installed on the utility pole, providing reliable support for subsequent monitoring work and ensuring the safety of substation workers.

The monitoring mechanism can be flexibly adjusted to the required monitoring angle, ensuring all-round, blind-spot-free monitoring of the work area and improving the accuracy and reliability of anti-collision monitoring.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0033] See attached document Figure 1 Appendix Figure 3 and attached Figure 4 An embodiment of this utility model provides a substation worker collision avoidance monitoring device based on optical ranging technology, including a back plate 1, which provides an overall support frame for the device. A mounting mechanism 2 is provided on the rear side of the back plate 1, which is used to fix the device to a utility pole. A mounting plate 3 is fixedly connected to the front side of the back plate 1, which is used to install a monitoring mechanism 4. A monitoring mechanism 4 is provided on the top of the mounting plate 3, which is used to monitor the distance between the worker and surrounding equipment.

[0034] The mounting mechanism 2 includes a U-shaped clamping plate 201. The outer wall of the U-shaped clamping plate 201 is fixedly connected to the rear side of the backing plate 1. The U-shaped clamping plate 201 is used to initially engage the utility pole for positioning. A sliding groove 202 is provided at the bottom of the U-shaped clamping plate 201, which provides a track for the sliding plate 203. The sliding plate 203 is slidably connected to the inner wall of the U-shaped clamping plate 201. The sliding plate 203 adjusts its fit with the utility pole by sliding. Side ears 204 are fixedly connected to both the left and right sides of the sliding plate 203. The side ears 204 are used to engage with fastening bolts 206 to fix the position of the sliding plate 203. Fixing blocks 20 are fixedly connected to both the left and right sides of the rear side of the backing plate 1. 5. The fixing block 205 is used to cooperate with the fastening bolt 206 to achieve fixation. The inner walls of the two side ears 204 are threaded with fastening bolts 206. The fastening bolts 206 are used to connect and fix the side ears 204 to the fixing block 205. The outer wall of the fastening bolt 206 is threaded to the inner wall of the fixing block 205, thereby locking the slide plate 203. Two reinforcing components 207 are provided on the left and right sides of the U-shaped card plate 201. The reinforcing components 207 are used to enhance the connection strength between the device and the utility pole. Binding components 208 are provided on the upper and lower sides of the rear side of the back plate 1. The binding components 208 are used to further fix the device to prevent loosening.

[0035] Specifically, during installation, align the opening of the U-shaped clamp 201 on the rear side of the back plate 1 with the utility pole, allowing the utility pole to be inserted into the inner wall of the U-shaped clamp 201. Push the slide plate 203 along the sliding groove 202 at the bottom of the U-shaped clamp 201. The side ears 204 on the left and right sides of the slide plate 203 move with it. Push the slide plate 203 until its inner wall is flush with the utility pole, according to the diameter of the utility pole. Take the fastening bolt 206, pass it through the inner wall of the side ear 204, align it with the fixing blocks 205 on the left and right sides of the rear of the back plate 1, and rotate the fastening bolt 206 so that its outer wall is threadedly connected to the inner wall of the fixing block 205. Fix the side ears 204 and the fixing block 205 to lock the slide plate 203. The connection strength is enhanced by the two reinforcing components 207 on the left and right sides of the U-shaped clamp 201. Then, use the binding components 208 on the upper and lower sides of the rear of the back plate 1 to wrap around the utility pole and fix it, forming a double fixation, so that the back plate 1 and the device are stably installed on the utility pole, providing support for monitoring work.

[0036] See attached document Figure 1 Appendix Figure 2 and attached Figure 5The monitoring mechanism 4 includes a rotating base 401, which provides a fulcrum for the rotating ring 402. The bottom of the rotating base 401 is fixedly connected to the top of the mounting plate 3, thus achieving fixed installation of the rotating base 401. The rotating ring 402 is rotatably connected to the outer wall of the rotating base 401, and the rotating ring 402 can drive the monitor 403 to rotate and adjust. The monitor 403 is fixedly connected to the top of the rotating ring 402. The monitor 403 is used to monitor distance through optical ranging technology. A screw 404 is threadedly connected to the inner wall of the mounting plate 3, and the screw 404 drives the transmission block 40 through rotation. 5. The screw 404 has a threaded connection to a transmission block 405 on its outer wall. The transmission block 405 is used to push the slider 406 to drive the monitor 403 to make fine adjustments. The outer wall of the transmission block 405 is slidably connected to the inner wall of the backing plate 1. The backing plate 1 provides sliding guidance for the transmission block 405. The left and right sides of the outer wall of the monitor 403 are fixedly connected to sliders 406. The sliders 406 are used to connect the monitor 403 and the transmission block 405. The outer walls of the two sliders 406 are slidably connected to the inner wall of the transmission block 405, so that the movement of the transmission block 405 can be transmitted to the monitor 403.

[0037] Specifically, the rotating ring 402 rotates around the outer wall of the rotating base 401 as a fulcrum. The top of the rotating ring 402 is fixed to the monitor 403. Rotating the rotating ring 402 can drive the monitor 403 to rotate. When adjusting the angle of the monitoring mechanism 4, the screw 404 connected to the inner wall of the mounting plate 3 is rotated. The rotation of the screw 404 drives the transmission block 405 to slide along the inner wall of the back plate 1 through the outer wall thread. Since the outer wall of the slider 406 on the left and right sides of the monitor 403 is slidably connected to the inner wall of the transmission block 405, the movement of the transmission block 405 pushes the monitor 403 through the slider 406. The monitor 403 rotates at a small angle with the rotating base 401 as the axis, until the required monitoring angle is reached.

[0038] See attached document Figure 1 and attached Figure 4The reinforcement component 207 includes a reinforcement block 2071. The outer wall of the reinforcement block 2071 is fixedly connected to the outer wall of the U-shaped clamping plate 201. The reinforcement block 2071 provides an installation base for the reinforcement bolt 2072. The inner wall of the reinforcement block 2071 is threaded with the reinforcement bolt 2072. The reinforcement bolt 2072 is tightened to abut against the side lug 204 for enhanced fixation. The front end of the reinforcement bolt 2072 is slidably connected to the outer wall of the side lug 204, preventing loosening by abutting against the side lug 204. The binding component 208 includes two straps 2081. The straps 2081 are used to wrap around the auxiliary fixing device of the utility pole. The front ends of both straps 2081 are fixedly connected to the rear side of the backing plate 1, realizing the connection between the straps 2081 and the backing plate 1. The rear end of the side strap 2081 is fixedly connected to a buckle 2082, which is used to lock in place with the buckle hole 2083. The outer wall of the left strap 2081 is provided with multiple buckle holes 2083, which can adjust the tightness of the strap 2081 to fit different utility poles. The top of the mounting plate 3 is fixedly connected to two side plates 5, which are used to protect the monitoring mechanism 4. The outer wall of the two side plates 5 is provided with multiple heat dissipation holes 6, which are used to dissipate the heat generated by the monitoring mechanism 4. The top of the two side plates 5 is fixedly connected to the same top plate 7, which is used to shield rainwater and dust. The top of the top plate 7 is provided with multiple guide grooves 8, which are used to guide rainwater to flow down quickly to prevent water accumulation.

[0039] Specifically, the rotating ring 402 rotates around the outer wall of the rotating base 401 as a fulcrum. The top of the rotating ring 402 is fixed to the monitor 403. Rotating the rotating ring 402 can drive the monitor 403 to rotate. When adjusting the angle, the screw 404 on the inner wall of the mounting plate 3 is rotated, and its thread drives the transmission block 405 to slide along the inner wall of the mounting plate 1. The slider 406 of the monitor 403 is slidably connected to the transmission block 405. The transmission block 405 pushes the monitor 403 through the slider 406, with the rotating base 401 as the axis. With the cooperation of the rotating ring 402, a small-angle rotation is completed. In the reinforcement component 207, the reinforcement block 2071 is fixed to the outer wall of the U-shaped card plate 201, and the reinforcement bolt 2072 is threaded to its inner wall. The front end abuts against the side ear 204 to enhance the fixation. The front end of the binding strap 2081 of the binding component 208 is connected to the abutment plate 1, and the right side buckle 2082 is fastened into the left side buckle hole 2083 for fixation. The side plate 5 and top plate 7 on the top of the mounting plate 3 play a protective role. The heat dissipation hole 6 dissipates heat, and the guide groove 8 guides water to ensure the stable operation of the device.

[0040] Working principle: During installation, first, align the opening of the U-shaped clamp 201 on the rear side of the backing plate 1 with the utility pole, so that the utility pole is inserted into the inner wall of the U-shaped clamp 201. Next, push the sliding plate 203 along the sliding groove 202 at the bottom of the U-shaped clamp 201. The side ears 204 on the left and right sides of the sliding plate 203 move synchronously with the sliding plate 203. Push the sliding plate 203 according to the diameter of the utility pole until the inner wall of the sliding plate 203 is tightly fitted with the utility pole. Then, take the fastening bolt 206, pass it through the inner wall of the side ears 204, and align it with the fixing blocks 205 on the left and right sides of the rear side of the backing plate 1. Rotate the fastening bolt 206 to tighten the bolt 206. The outer wall of the 6 is threadedly connected to the inner wall of the fixing block 205. The locking force of the thread fixes the side ear 204 to the fixing block 205, thereby firmly locking the position of the slide plate 203 and preventing it from sliding during subsequent use. Then, the connection strength between the device and the utility pole is further enhanced by the two reinforcing components 207 on the left and right sides of the U-shaped clamp plate 201, ensuring a more stable connection. Finally, the binding components 208 on the upper and lower sides of the back plate 1 are used to wrap it around the utility pole and fix it, forming a double fixation, ensuring that the back plate 1 and the entire device can be stably installed on the utility pole, providing reliable support for subsequent monitoring work.

[0041] Furthermore, with the rotating base 401 as the fulcrum, the rotating ring 402 can rotate freely around the outer wall of the rotating base 401. Since the top of the rotating ring 402 is fixedly connected to the monitor 403, the rotating ring 402 drives the monitor 403 to rotate. When it is necessary to adjust the angle of the monitoring mechanism 4, the screw 404 connected to the inner wall of the mounting plate 3 is rotated. When the screw 404 rotates, its outer wall thread drives the transmission block 405 to slide along the inner wall of the back plate 1. Since the outer wall of the slider 406 on the left and right sides of the monitor 403 is slidably connected to the inner wall of the transmission block 405, when the transmission block 405 moves, it will push the monitor 403 through the slider 406. At this time, the monitor 403 rotates at a small angle with the rotating base 401 as the axis and with the cooperation of the rotating ring 402 until the required monitoring angle is reached.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
