Description

Technical Field

[0001] This utility model relates to the field of substation protection technology, and in particular to a substation small animal monitoring device. Background Technology

[0002] In the power system, substations are a key link, undertaking core functions such as regulating voltage and current, receiving and distributing electrical energy. With economic development and increasing electricity demand, substations are built in suburban and mountainous areas. These areas are inhabited by many small animals such as birds, rats, snakes and rabbits. Therefore, small animals are prone to move inside high-voltage electrical equipment in substations, causing phase-to-phase short circuits and ground faults on the busbars, resulting in damage or even burnout of electrical equipment.

[0003] To combat small animal invasions, current measures mainly include regular inspections, installing barriers, placing rat traps, and using rodenticides, but these methods have obvious limitations.

[0004] Chinese patent application number 202120728478.1 discloses a real-time monitoring device for preventing small animal intrusion in substations, including a monitor body and an audible and visual alarm. The front surface of the monitor body is equipped with a pyroelectric infrared sensor and a camera. The front surface of the pyroelectric infrared sensor is connected to a Fresnel filter lens. The monitor body contains an MCU, an image sensor, a wireless communication module, a Bluetooth module, and a battery. When a small animal is detected by the pyroelectric infrared sensor, it will trigger the audible and visual alarm and the camera to take a picture. Although there are some existing detection methods based on sensor fusion, regular inspections by staff are still required. The location of the small animal intrusion cannot be accurately marked, resulting in low inspection and maintenance efficiency, easy formation of blind spots, and inability to detect small animal intrusions in time and take measures. Utility Model Content

[0005] The purpose of this invention is to solve the problem of low inspection and maintenance efficiency when small animals invade in the existing technology, and to propose a small animal monitoring device for substations.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a small animal monitoring device for substations, comprising a monitor body and a pipe casing.

[0007] The pipe shell has a hollow structure, and the inner side of the pipe shell is provided with a side plate. The monitor body is provided with swing components on both sides. The swing components include a fixed plate, a hinge joint, a first motor and a second motor. The first motor drives the rotating column through gear transmission, and the second motor drives the rotating plate to swing, so that the rotating plate can be switched to a state perpendicular or parallel to the pipe shell.

[0008] The bottom of the side plate is equipped with a horizontal moving component, which drives the monitor body to move axially along the pipe shell.

[0009] In some embodiments, the front of the monitor body is provided with an alarm light bulb, and the top of the monitor body is provided with an antenna and a charging port.

[0010] In some embodiments, the horizontal movement assembly includes a threaded shaft and an internal threaded block, the internal threaded block being fixed to the top of the connecting seat, and a third motor driving the threaded shaft to rotate via a transmission belt, thereby causing the monitor body to move horizontally.

[0011] In some embodiments, the top of the internal threaded block is provided with a limiting strip that cooperates with the limiting groove at the bottom of the side plate.

[0012] In some embodiments, when the rotating plate is perpendicular to the pipe housing, it forms a closed unit to block small animals.

[0013] In some embodiments, multiple monitor bodies are distributed along the outer shell of the pipe, forming multiple enclosed units through a linkage rotating plate.

[0014] In some embodiments, the perforated structure of the pipe casing is used to enhance the propagation of audible and visual alarms and heat dissipation, and the top of the pipe casing is provided with a removable cover plate for manual intervention to detect the alarm.

[0015] In some embodiments, the horizontal movement of the monitor body is used to reduce the enclosed unit space, assisting in the capture of small animals.

[0016] In some embodiments, the hinge joint is coaxially connected to the rotating column to achieve synchronous angle adjustment of the rotating plate.

[0017] In some embodiments, the horizontal movement component travels across the entire length of the pipe housing, and the monitor body incorporates an infrared sensor for detecting small animal activity.

[0018] Compared with the prior art, this utility model provides a small animal monitoring device for substations, which has the following beneficial effects.

[0019] 1. This utility model, by setting multiple monitoring units inside the pipe shell, uses infrared sensors to monitor in real time. When a small animal is detected entering, the alarm light bulb emits an audible and visual alarm, which can quickly and accurately locate the current position of the small animal, greatly improving monitoring efficiency and eliminating blind spots in inspection.

[0020] 2. In this utility model, when a small animal enters the pipe, the alarm light bulb first emits an audible and visual signal to disperse it. If the animal is not dispersed successfully, the rotating plate can rotate to be perpendicular to the pipe shell, sealing the pipe and preventing the small animal from continuing to move into the substation. At the same time, the horizontal moving component pushes the monitor body and the rotating plate to push the small animal out of the pipe, or multiple rotating plates can form a closed unit to restrict the activity area of ​​the small animal, making it convenient for staff to open the top cover of the pipe shell to capture it, thus avoiding repeated intrusions by small animals and damage to the equipment inside the station.

[0021] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] Example 1

[0035] Reference Figure 1-2 A small animal monitoring device for a substation includes a monitor body 1, an alarm light bulb 2 on the front side of the monitor body 1, an antenna 3 and a wiring charging port 4 on the top of the monitor body 1, and an infrared sensor built into the monitor body 1 to detect small animal activities.

[0036] The bottom of the monitor body 1 is provided with a connecting seat 5. The lower surface of the connecting seat 5 is provided with an adhesive layer 501. The lower surface of the adhesive layer 501 is provided with a plastic sticker. The connecting seat 5 serves as a mounting base for the monitor body 1. In one embodiment, the connecting seat 5 can be adhered to a preset installation area through the adhesive layer 501. The smooth surface of the plastic sticker is in contact with the adhesive layer 501 to prevent the adhesive layer 501 from being contaminated. The monitor body 1 and the connecting seat 5 are connected through a hinge seat 502. The monitor body 1 can adjust its angle through the hinge seat 502.

[0037] Example 2

[0038] Reference Figure 1-9 A small animal monitoring device for a substation includes a pipe shell 6, with a side plate 7 on the inner side of the pipe shell 6. Swinging components 8 are provided on both sides of the monitor body 1. Each swinging component 8 includes a fixed plate 801. A hinge joint 802 and a first motor 803 are provided at the end of the fixed plate 801 away from the monitor body 1. A first gear 8031 ​​is provided at the output end of the first motor 803. A second motor 804 is connected to the fixed plate 801 via the hinge joint 802. A rotating plate 805 is provided at the rotating end of the second motor 804. A rotating column 8042 is fixedly connected to the second motor 804 via a connecting plate 8041. A second gear 8043, corresponding to and cooperating with the first gear 8031, is provided at the top of the rotating column 8042. The rotating column 8042 is rotatably connected to the middle of the hinge joint 802.

[0039] Among them, the outer casing 6 of the pipe serves as a ventilation duct or line duct of the substation. The outer casing 6 of the pipe is connected to the substation. If the outer casing 6 of the pipe is laid at a high place, a ladder corresponding to the outer casing 6 is provided along the path of the outer casing 6.

[0040] The monitor body 1 has multiple sets of equipment inside the pipe shell 6. The first motor 803 in the swing assembly 8 on the monitor body 1 drives the second gear 8043 through the first gear 8031 ​​to adjust the angle of the rotating plate 805 so that the rotating plate 805 is perpendicular to the pipe shell 6. Two adjacent rotating plates 805 form a closed unit with the pipe shell 6. Multiple rotating plates 805 form multiple closed units. The top of the pipe shell 6 is provided with a detachable cover plate, which is fixed to the pipe shell 6 with bolts. After the cover plate is removed, small animals inside the pipe shell 6 can be captured manually.

[0041] When the rotating plate 805 is perpendicular to the pipe housing 6, the second motor 804 drives the rotating plate 805 to rotate toward the outlet of the pipe housing 6, cleaning the impurities inside the pipe housing 6 outward.

[0042] The bottom of the side panel 7 is provided with a horizontal movement component for the monitor body 1. Each monitor body 1 has a horizontal movement component at its bottom. The horizontal movement component drives the monitor body 1 to move horizontally inside the monitor body 1, thereby expanding the monitoring range of the monitor body 1.

[0043] The horizontal moving assembly includes a threaded shaft 9 and an internal threaded block 903. The internal threaded block 903 is located at the top of the connecting seat 5, and the threaded shaft 9 passes through the internal threaded block 903. A third motor 901 is located at the bottom of the side plate 7. A rotating disk is located at the output end of the third motor 901, and a transmission belt 902 is located on the rotating disk. The rotating disk is connected to the threaded shaft 9 via the transmission belt 902. The rotating disk has external teeth on its circumference, the transmission belt 902 has internal teeth on its inner side, and the threaded shaft 9 has external teeth on its end circumference. Through the engagement of the external teeth on the rotating disk, the external teeth at the end of the threaded shaft 9, and the internal teeth on the transmission belt 902, the threaded shaft 9 is driven to rotate when the third motor 901 rotates.

[0044] The top of the internal thread block 903 is provided with a limiting strip 904, and the bottom of the side plate 7 is provided with a limiting groove 905 that corresponds to and cooperates with the limiting strip 904. Both the limiting strip 904 and the limiting groove 905 are inverted T-shaped structures.

[0045] In this invention, the monitor body 1 is rotated to a vertical position via the hinge seat 502. In the initial state, the first motor 803, through the meshing of the first gear 8031 ​​and the second gear 8043, causes the rotating plate 805 and the connecting plate 8041 to rotate around the rotating column 8042 as the center, so that the rotating plate 805 is parallel to the monitor body 1. The pipe shell 6 is a hollow pipe, which facilitates the propagation of sound and light when the monitor body 1 is under audible and visual alarm. On the other hand, the hollow structure increases the contact area between the air and the internal equipment or circuits of the pipe shell 6, thereby improving the heat dissipation efficiency of the internal equipment.

[0046] During use, multiple monitoring units 1 inside the pipe shell 6 monitor whether there are small animals inside the pipe shell 6. The multiple monitoring units 1 can easily locate the current position of the small animals. Specifically, when a small animal is detected entering the outlet of the pipe shell 6, the alarm light bulb 2 first emits an audible and visual alarm signal to disperse the small animal. If the small animal is not dispersed and continues to move into the substation through the pipe shell 6, the first motor 803 in the middle of the pipe shell 6 drives the second gear 8043 to rotate through the first gear 8031. When the rotating column 8042 rotates, it drives the second motor 804 and the rotating plate 805 to rotate inward around the rotating column 8042 as the center, and is perpendicular to the pipe shell 6, thus sealing the pipe shell 6. At this time, the small animal cannot continue to move inward through the gap between the rotating plate 805 and the pipe shell 6, thereby achieving the isolation of the small animal.

[0047] Subsequently, the third motor 901 starts and drives the transmission belt 902 to rotate through the rotating disk. When the transmission belt 902 rotates, it synchronously drives the end of the threaded shaft 9 to rotate. When the threaded shaft 9 rotates, under the limiting action of the limiting strip 904 by the limiting groove 905, the internal thread block 903, the connecting seat 5 and the monitor body 1 move horizontally along the threaded shaft 9, so that the monitor body 1 and the rotating plate 805 move horizontally synchronously. The direction of the horizontal movement of the monitor body 1 is from the inside of the pipe shell 6 to the outlet of the pipe shell 6, pushing the small animal out of the pipe shell 6.

[0048] Furthermore, to prevent small animals from repeatedly entering the pipe shell 6, after the monitor body 1 located at the outlet of the pipe shell 6 has repeatedly detected a small animal passing by, when the small animal continues to enter the pipe shell 6, the rotating plate 805 near the outlet of the pipe shell 6 remains parallel to the pipe shell 6 under the action of the first motor 803. The small animal will continue to move into the pipe shell 6. When it reaches the next set of monitor bodies 1, the monitor body 1 detects the small animal approaching. At this time, the rotating plate 805 near the outlet of the pipe shell 6 rotates inward under the action of the first motor 803, perpendicular to the pipe shell 6. At the same time, the rotating plate 805 on the adjacent set of monitor bodies 1 also flips inward under the action of the first motor 803, perpendicular to the pipe shell 6. At this time, the two rotating plates 805 and the pipe shell 6 form a closed unit. The small animal is confined to a specific area, and the alarm light bulb 2 emits an alarm signal. The alarm light and alarm sound are transmitted outward through the perforated gaps in the pipe shell 6, so that the staff can quickly locate the current position of the small animal. In addition, to facilitate the capture of the small animal, after the two rotating plates 805 have completed the confinement of the small animal, the third motor 901 drives the threaded shaft 9 to rotate. The internal threaded block 903, the connecting seat 5 and the monitor body 1 move horizontally, so that the two adjacent sets of monitor bodies 1 move closer to each other, reducing the space of the enclosed unit. After the staff arrives at the enclosed unit according to the sound and light alarm signal, they remove the cover plate on the top of the pipe shell 6 and capture the small animal from the pipe shell 6. Then, driven by the first motor 803, the rotating plate 805 rotates around the rotating column 8042 until it is parallel to the pipe shell 6, completing the reset.
