Description

Technical Field

[0001] This utility model relates to the technical field of rat-repelling devices for substations, specifically a domino-style rat-repelling device for substations. Background Technology

[0002] Substations are a crucial component of power systems, and their safe and reliable operation is essential for the overall safety and reliability of the power system. Because substations typically occupy large areas, house numerous pieces of equipment, and contain potentially hazardous equipment, they are generally located in areas with low personnel traffic. Rats, as rodents, have a gnawing behavior; when they enter a substation, they often gnaw on equipment or wiring, disrupting normal operation. In thermal power plants, rodent control is generally achieved through regular manual inspections or the use of rodenticides. However, manual inspections increase the workload of staff, and rodenticide use poses potential threats to the environment and human health. Therefore, achieving efficient rodent control in substations while minimizing negative impacts is a pressing issue that needs to be addressed. Utility Model Content

[0003] The purpose of this invention is to provide a domino-style rat-repelling device for substations. This device uses the impact sound produced by the successive falling of multiple dominoes to repel rats. It has no potential impact on the ecological environment or human health. At the same time, dominoes are placed around the perimeter of the substation to achieve all-round rat repelling.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a domino-style rat-repelling device for substations, including a controller, an infrared camera, and four sets of repelling branch components. The controller is electrically connected to the infrared camera.

The alignment slots are connected to the hollow interior of the hollow truncated square pyramid. The length of the hollow truncated square pyramid is distributed along the width of the dominoes. The width of the dominoes is the same as the width of the support plate. The dominoes include an upper triangular plate and a lower square plate, which are connected vertically as a single unit. When both sides of the lower square plate are engaged in the corresponding alignment slots, the width of the corresponding domino is aligned in the same direction as the width of the movable support frame.

[0006] Furthermore, each edge of the upper triangular plate is provided with an arc-shaped chamfer, and the width of the upper opening of the hollow truncated square pyramid is 1.5-2.0 times the thickness of the upper triangular plate.

[0024] The following will describe specific embodiments and appendices. Figure 1-9 The technical solutions in the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some preferred embodiments of this utility model, and not all embodiments. Those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0025] This utility model provides a domino-style rat deterrent device for substations (such as...). Figure 1As shown, the system includes a controller, an infrared camera, and four sets of rat-repelling branch components. The controller can be a PLC controller, and the infrared camera is a commonly used technology in the existing technical field. The controller and the infrared camera are electrically connected. The infrared camera can monitor the corresponding rat monitoring area in the substation and send an alarm signal to the controller when a rat is detected. In practical applications, the infrared camera can be used for online real-time monitoring of areas within and around the substation that require rat control. The method for identifying rats in the monitored area using the infrared camera is also existing technology, such as the Chinese utility model patent with authorization announcement number CN118314532B, which discloses a technical solution entitled "A Rat Recognition Method Based on Deep Learning for Substation Infrared Images." Using the technical solution provided by the aforementioned utility model patent, the infrared camera can be fully utilized. The system identifies rats within a monitored area, enabling automatic monitoring of their presence. When an infrared camera detects a rat, it immediately sends an alarm signal to the controller. Upon receiving the alarm signal, the controller executes subsequent control procedures according to the pre-set program. In practical applications, if an infrared camera cannot be used, a millimeter-scale radar sensor can be used as a substitute. In this case, millimeter-scale radar sensors are installed in the corresponding monitoring area and electrically connected to the controller. When a millimeter-scale radar sensor detects a moving object within its monitoring range, it sends an alarm signal to the controller. Using millimeter-scale radar sensors for monitoring not only rats but also other moving animals can be monitored, thus expanding the monitoring range to some extent. The four sets of driving branch components are arranged in a square pattern after being connected end to end, meaning they can be installed and arranged along the perimeter of the substation. Each set of driving branch components includes a positioning bracket 1, a movable support frame 2, a first lifting mechanism, a second lifting mechanism, a leveling guide cover 5, dominoes 6, a photoelectric detection switch 7, and a toggle mechanism. The positioning bracket 1 includes a support plate 11, which is used to fix the entire driving branch component on the ground. In practical applications, to ensure stable support for the support plate 11, a [missing information - likely a device or mechanism] can be provided at the bottom of the support plate 11. Several insert rods 12 are used to insert into the ground. To facilitate the four supporting plates 11 to be connected end-to-end to form a square structure, the supporting plates 11 are L-shaped. Several dominoes 6 are distributed at equal intervals along the length of the supporting plates 11. All the dominoes 6 on the four supporting plates 11 are arranged in a square circle, and the distance between two adjacent dominoes 6 is less than one-third of the height of the dominoes 6. After all the dominoes 6 are arranged at equal intervals in the above manner, when one of the dominoes 6 falls,This will cause all subsequent dominoes 6 to fall sequentially. During the fall, the dominoes 6 will make a crashing sound. As multiple dominoes 6 fall, the crashing sound becomes louder and louder, thus using the crashing sound to scare away rats in the vicinity. The first lifting mechanism can move the movable support frame 2 up and down and position it directly above the dominoes 6. A straightening guide cover 5 is installed directly above each domino 6. The straightening guide cover 5 is used to guide the upward straightening of the corresponding domino 6. The straightening guide cover 6 is fixedly installed at the lower part of the movable support frame 2. The second lifting mechanism is installed on the movable support frame 2 and is used to drive the lifting and positioning of all the dominoes 6 in the corresponding drive branch assembly. In practical applications, the fallen dominoes 6 are continuously pulled into the straightening guide cover 5 by the second lifting mechanism. When the dominoes are completely fallen... After the rope of domino 6 is pulled, domino 6 is positioned and corrected under the guidance of the straightening guide cover 5. That is, the position of domino 6 is the same as before it tipped over, except that it is suspended relative to the support plate 11. Two mounting holes are provided on the straight end 11 of the support plate 11. A photoelectric detection switch 7 is provided in each mounting hole 11, and the two photoelectric detection switches 7 are located on both sides of the corresponding domino 6. In practical applications, when the domino 6 between the two photoelectric detection switches 7 tipped over, the photoelectric detection switches 7 can detect the tipped domino 6 no matter which photoelectric detection switch 7 it tipped over towards, thus facilitating the monitoring of the status of the entire domino circle. The tossing mechanism is used to push over the domino 6 located between the two photoelectric detection switches 7. The photoelectric detection switches 7 and the tossing mechanism are electrically connected to the controller. In practical applications, a domino ring composed of multiple dominoes (6) can achieve both passive and active deterrence of mice. Passive deterrence occurs when a mouse actively knocks down a domino, triggering a chain reaction of other dominoes falling, thus using the sound of the falling dominoes to frighten and drive the mouse away. Active deterrence occurs when an infrared camera detects a mouse and sends an alarm to the controller. Upon receiving the alarm, the controller activates the corresponding trigger mechanism according to a pre-programmed sequence, causing that domino to fall, which in turn triggers a chain reaction of falling dominoes, again using the sound of the falling dominoes to frighten and drive the mouse away.

[0026] Based on the above embodiments, the specific implementation of the alignment guide cover 5 is as follows: the lower part of the alignment guide cover 5 is a hollow truncated square pyramid 51, and the hollow truncated square pyramid 51 is vertically continuous, that is, an upper opening 511 is opened in the upper part of the hollow truncated square pyramid 51, and a lower opening is opened in the lower part. When the domino 6 enters the alignment guide cover 5, it enters the alignment guide cover 5 through the lower opening. The hollow truncated square pyramid 51 is hollow, thus forming a truncated square pyramid-shaped guide space inside it. When the domino 6 enters the hollow truncated square pyramid... After the dominoes 6 rise continuously within the hollow truncated pyramid 51, the inclined sidewalls inside the dominoes 6 guide them, causing them to move continuously towards the upward opening 511. Two symmetrically arranged alignment slots 52 are provided along the length of the upper part of the hollow truncated pyramid 51, with the upper part of each slot closed. These slots communicate with the hollow interior of the truncated pyramid 51. The length of the hollow truncated pyramid 51 is distributed along the width of the dominoes 6. The width direction of the domino 6 is the same as the width direction of the supporting plate 12. The domino 6 includes an upper triangular plate 61 and a lower square plate 62, which are connected vertically as a single unit. When both sides of the lower square plate 62 are engaged in the corresponding alignment slots 52, the width direction of the corresponding domino 6 is aligned in the same direction as the width direction of the movable supporting plate 21. The process of the domino 6 being pulled into the alignment guide cover 5 and achieving posture alignment is as follows: as the domino 6 moves... As the dominoes 6 continue to rise, the upper part of the upper triangular plate 61 first enters the lower opening. As the dominoes 6 continue to rise, the upper part of the upper triangular plate 61 enters the upper opening 511. Once the upper part of the upper triangular plate 61 is inside the upper opening 511, as the dominoes 6 continue to rise, the inclined inner wall of the hollow truncated pyramid 51 guides the continuous movement of the sides of the upper triangular plate 61, causing the dominoes 6 to rotate at a certain angle, ultimately resulting in the two sides of the lower square plate 62 precisely engaging in the corresponding alignment slots 52. Figure 8 As shown, after the two sides of the square plate 62 are inserted into the two alignment slots 52, the domino 6 is aligned. As the domino 6 continues to rise, when the upper edge of the upper triangle plate 61 is engaged with the upper edge of the alignment slot 52, the rise of the domino 6 stops, and the alignment of the domino 6 is finally completed.

[0027] Based on the above embodiments, to facilitate the smooth rotation of the upper triangular plate 61 within the alignment guide cover 5, and thus facilitate its posture alignment guidance, an arc-shaped chamfer 611 is provided at each edge of the upper triangular plate 61. To facilitate the smooth insertion of the top of the upper triangular plate 61 into the upper opening 511, the width of the upper opening 511 of the hollow truncated pyramid 51 is 1.5-2.0 times the thickness of the upper triangular plate 61. In this specific embodiment, the width of the upper opening 511 is set to 1.8 times the thickness of the upper triangular plate 61. This ensures that even if the width direction of the domino 6 is not consistent with the width direction of the upper opening 511, the upper part of the upper triangular plate 61 can still smoothly enter the upper opening 511, thereby guaranteeing the subsequent posture alignment of the domino 6 within the alignment guide cover 5.

[0028] Based on the above embodiments, the specific implementation of the movable support frame 2 is as follows: The movable support frame 2 includes a lower support frame 21, a middle support frame 22, and an upper support frame 23. The lower support frame 21, the middle support frame 22, and the upper support frame 23 are fixedly connected from bottom to top. The alignment guide cover 5 is fixedly installed on the lower support frame 21. The first lifting mechanism includes a plurality of first electric push rods 3. The first electric push rods 3 are fixedly installed on the support plate 11. The telescopic end of the first electric push rod 3 passes through the support plate 11 and is fixedly connected to the middle support frame 22. In actual application, the telescopic movement of the telescopic end of the first electric push rod 3 is used to realize the up-and-down movement and positioning of the entire movable support frame 2. During the up-and-down movement of the movable support frame 2, the up-and-down movement of the alignment guide cover 5 is realized simultaneously.

[0029] Based on the above embodiments, the specific implementation of the second lifting mechanism is as follows: The second lifting mechanism includes a lifting plate 41, a pull rope 42, and a plurality of second electric push rods 43. The plurality of second electric push rods 43 are inverted and arranged on the upper support frame 23. The lifting plate 41 is fixedly arranged at the lower part of the telescopic rods of the plurality of second electric push rods 43. The upper part of each domino 6 is fixedly connected to the lower part of a corresponding pull rope 42. The upper part of the pull rope 42 passes through the corresponding hollow truncated square pyramid 51 and is fixedly connected to the lower part of the lifting plate 41. The mechanism operates within the movable support frame 2. During the up-and-down movement, the lifting plate 41, the pull rope 42, and the second electric push rod 43 all move up and down synchronously. During the extension and retraction of the second electric push rod 43, the lifting plate 41 is driven to move up and down. The up-and-down movement of the lifting plate 41 pulls the upper end of the pull rope 42 to move up and down. During the upward movement of the lifting plate 41, when the pull rope 42 is stretched and tightened, the lifting plate 41 continues to rise, thus realizing the lifting of the domino 6. Subsequently, the domino 6 can be smoothly pulled into the alignment guide cover 5, thereby using the guiding effect of the alignment guide cover 5 to realize the posture alignment of the domino 6.

[0030] Based on the above embodiments, the specific implementation of the actuating mechanism is as follows: The actuating mechanism includes a drive motor 81 and a lever 82. The drive motor 81 is disposed on the outer side of the hollow truncated pyramid 51 located at the outermost straight end 11 of the support plate 11. Specifically, a support frame is fixedly disposed on the outer side of the corresponding hollow truncated pyramid 51, and the drive motor 81 is fixedly disposed on the support frame. The lever 82 is disposed on the drive shaft of the drive motor 81. The drive motor 81 drives the lever 82 to rotate, thereby achieving the initial position at the corresponding location. In practical application, to topple the domino 6 from its initial upright position, the height of the lever 82 is slightly lower than the top of the upper triangular plate 61. When the lever 82 is in the stopped state, its length direction is in the same direction as the width direction of the domino 6. When the lever 82 rotates 180 degrees, the domino 6 is topped. The lever 82 stops at its initial placement position after rotating one full circle. The drive motor 81 is electrically connected to the controller. After the controller sends a start signal to the drive motor 81, the drive motor 81 drives the lever 82 to rotate, thereby topping up the corresponding domino 6.

[0031] Based on the above embodiments, to improve the noise effect emitted after the dominoes 6 tip over, a through hole is provided in the middle of the lower square plate 62, a thin steel plate 63 is provided in the through hole, and an elastic rod 64 located on one side of the thin steel plate 63 is provided in the through hole. A solid sphere 65 is fixedly provided at the outer end of the elastic rod 64. When the dominoes 6 tip over, the solid sphere 65 swings up and down under the action of gravity and the elastic rod 64. During the swinging process, the solid sphere 65 frequently strikes the thin steel plate 63, thereby producing noise. To further improve the rat-repelling effect of the dominoes 6, reflective strips are provided at the edges of the upper triangular plate 61 and the lower square plate 62. Under the condition of light source illumination, during the process of the dominoes 6 falling, the light-emitting characteristics of the reflective strips can visually stimulate the rats, thereby causing a certain degree of panic in the rats and forcing them to flee.

[0032] The operation control method for a domino-type rat deterrent device for substations described above also includes the following operation steps:

[0033] S1. According to the program settings in the controller, both the lifting plate 41 and the leveling guide cover 5 are at their initial heights. When the lifting plate 41 is at its initial height, the dominoes 6 are placed on the support plate 11 and the pull rope 42 is initially taut. The height of the lifting plate 41 is controlled by the controller through the extension and retraction of the second electric push rod 43. When the leveling guide cover 5 is at its initial height, it will not obstruct the tipping of the dominoes 6 below it. The height of the leveling guide cover 5 is controlled by the controller through the extension and retraction of the first electric push rod 3. Then, the height of the lifting plate 41 is lowered, and the descent distance of the lifting plate 41 is equal to the dominoes' height. When the lifting plate 41 descends to twice the height of the domino 6, the lower pull rope 42 is in a slack state. When the lifting plate 41 descends to twice the height of the domino 6, the pull rope 42 will not interfere with the falling of the domino 6, thus ensuring the smooth falling of the domino 6 and guaranteeing a chain reaction of falling dominoes 6. The pull rope 42 can be made of three strands of sewing thread crisscrossed, which makes the pull rope 42 lightweight while ensuring its strength. The lightweight material of the pull rope 42 will not affect the falling of the domino 6.

[0034] S2. Infrared cameras provide real-time monitoring of the corresponding monitoring area;

[0035] S3. When the infrared camera detects a mouse moving in the monitored area, it sends an alarm signal to the controller.

[0036] S4. When the controller receives an alarm signal from the infrared camera, it starts one of the four drive motors 81 according to the set program. In practical applications, the four drive motors 81 are numbered so that the controller can control them accordingly. After the corresponding drive motor 81 starts, it drives the corresponding lever 82 to rotate one revolution and then stops. During the revolution of the lever 82, the corresponding domino 6 is pushed over. After the drive motor 81 starts, the controller starts timing synchronously. When the timing reaches the set value T1, the controller activates all photoelectric detection switches 7. The photoelectric detection switches 7 transmit the signal of whether or not a domino 6 is detected to the controller. When neither of the two photoelectric detection switches 7 in a set of drive branch components detects a domino 6, the controller activates the drive motor 81 in the corresponding drive branch component, causing it to drive the lever 82 to rotate one revolution. In practical applications, the time T1 is determined by the time required for all the dominoes 6 on the support plate 11 to be tilted over at once. Generally, it is necessary to make T1 should take longer than the time required for all dominoes 6 to tip over at once. For example, if it takes one minute for all dominoes 6 to tip over at once, T1 can be set to two minutes. This ensures that all dominoes 6 will tip over automatically if they can complete the tipping process. In case of unforeseen circumstances, some dominoes 6 in a set of drive branch components may fail to tip over. In this case, to facilitate the tipping of dominoes 6, photoelectric detection switch 7 is used to trigger the tipping of dominoes 6. If neither of the two photoelectric detection switches 7 detects a tilted domino 6, it is highly likely that the domino 6 located between them has not fallen. In this case, the signal from the photoelectric detection switch 7 indicating that the domino 6 has not been detected is sent to the controller. The controller then starts the corresponding drive motor 81 to push the domino 6 down again. In practical applications, multiple photoelectric detection switches 7 are numbered so that the controller can start the corresponding drive motor 81 based on the signal from the photoelectric detection switch 7 with different numbers.

[0037] S5. When the drive motor 81 in the corresponding drive branch assembly starts, the controller starts timing again. When the timing reaches the set value T1, the controller activates the second electric push rod 43. During the controller's timing of the T1 time period again, under normal circumstances, all dominoes 6 in the drive branch assembly will tip over under the push of the lever 82. Then, when the T1 time period ends, it can be ensured that all dominoes 6 have tipped over. The second electric push rod 43 causes the lifting plate 41 to slowly rise to the alignment height, which is the height at which the lifting plate 41 pulls the dominoes 6 forward. As the dominoes are lowered into the alignment guide 5, the two sides of the upper triangular plate 61 are positioned at the height of the upper edge of the corresponding alignment guide groove 52. During the slow ascent of the lifting plate 41, the dominoes 6 are slowly pulled into the alignment guide 5 by the corresponding pull rope 42. Through the guiding action of the alignment guide 5, the placement posture of the dominoes 6 is adjusted. When the lifting plate 41 reaches the alignment height and stops rising, the dominoes 6 are aligned by the alignment guide 5. At this point, the width direction of the dominoes 6 is the same as the width direction of the supporting plate 11, but the dominoes 6 are positioned relative to the support plate 11. With the support plate 11 suspended in mid-air, and the lifting plate 41 stopping at the aligned height position, the controller activates the first electric push rod 3 to lower the entire movable support frame 2. Once the movable support frame 2 reaches the designated height, it stops descending. At this point, the dominoes 6 are stably placed on the support plate 11. The alignment guide cover 5 remains fitted over the upper part of the dominoes 6. Then, the second electric push rod 43 is activated, causing the lifting plate 41 to descend a distance 1.2 times the descent distance of the movable support frame 2. The purpose of lowering the lifting plate 41 is to slack off the pull rope 42, so that... During the subsequent overall lifting and lowering of the movable support frame 2, the pull rope 42 will not pull the dominoes 6, thus ensuring the stability of the dominoes 6. After the lifting plate 41 descends to the correct position, the first electric push rod 3 is activated again to return the movable support frame 2 to its initial height. After the movable support frame 2 returns to its initial height, the second electric push rod 43 is activated again to return the lifting plate 41 to its initial height position. When the lifting plate 41 returns to its initial height position and stops, the fallen dominoes 6 are repositioned and reset. After all the dominoes 6 are repositioned and reset, preparations can be made again for subsequent rat driving.

[0038] In practical applications, this device can be used to repeatedly scare away rats, eliminating the need for manual rat chasing and reducing the workload of staff.

[0039] In this utility model, "left" and "right" are relative positions used for the convenience of describing positional relationships, and therefore cannot be understood as absolute positions as a limitation on the scope of protection.

[0040] Except for the technical features described in the specification, all other technologies are known to those skilled in the art.

However, the present invention is not limited to the above embodiments and examples. For those skilled in the art, several improvements and modifications can be made without departing from the concept of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
