Description

Technical Field

[0001] This utility model relates to the field of surveillance camera equipment technology, specifically a monitoring device for power grid video surveillance systems. Background Technology

[0002] In a power system, the term refers to the facilities and equipment that connect power generation and consumption. It is an intermediate link in the transmission and distribution of electrical energy. It mainly consists of transmission lines, substations, distribution stations, and distribution lines that are connected into a grid. The unified whole that connects power generation and consumption, consisting of transmission, transformation, distribution equipment, and corresponding auxiliary systems, is usually called the power grid.

[0003] For example, patent CN219867015U discloses a monitoring device for a power grid video monitoring system, belonging to the technical field of monitoring camera equipment. It includes a mounting frame with a groove at its bottom, a bearing fixed to its inner top surface, a movable plate on its inner bottom surface, and a telescopic cylinder fixed to its inner side wall. The bearing is connected to a rotating rod, a first gear is fixed to the rotating rod, and a second gear is fixed to its other end. The piston rod of the telescopic cylinder is connected to a movable plate. Several first racks meshing with the first gear are fixed to the movable plate near the first gear, and several second racks meshing with the second gear are fixed to the movable plate near the second gear. A sliding plate slidably connected to the groove is fixed to the bottom of the movable plate, and a mounting plate is fixed to the bottom of the mounting plate. A monitoring mechanism is provided at the bottom of the mounting plate.

[0004] Through the above settings, existing technology allows for free movement and position adjustment, expanding the monitoring range and meeting the growing needs of enterprises. However, existing monitoring devices have the following drawbacks during operation:

[0005] The aforementioned device, with its telescopic cylinder, first rack plate, second rack plate, first gear, and second gear, is only designed to enable the camera body to move left and right. This structure is overly complex and has a limited effect. Furthermore, the stability is low when the first rack plate is driven to move by the telescopic cylinder and the first gear is driven to rotate by the first rack plate. Utility Model Content

[0006] The present invention aims to provide a monitoring device for a power grid video monitoring system, mainly to solve the technical problem that existing technologies use multiple structures to achieve only the movement of the camera body, thus causing structural complexity.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A monitoring device for a power grid video surveillance system includes a rectangular block, a camera body, and a cavity. A rectangular groove is provided at the bottom of the cavity. A slider is slidably connected to the inner wall of the rectangular groove. A rotating shaft is rotatably connected through the top of the slider. A connecting plate is fixedly connected to the lower end of the rotating shaft, and the bottom of the connecting plate is fixedly connected to the top of the camera body. A gear is slidably connected to the outer wall of the rotating shaft. Guide blocks are symmetrically fixedly connected to the inner wall of the cavity, and the ends of the guide blocks are inclined structures. A drive assembly is fixedly connected to the side wall of the cavity. A limit assembly is provided at the bottom of the gear. A meshing assembly is fixedly connected to the inner wall of one end of the cavity.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working Principle: In use, this device operates through a drive component, which moves the rotating shaft left and right. During this movement, the slider and connecting plate slide along the inner side of a rectangular groove, thereby moving the camera body left and right via the connecting plate. A limiting component prevents the rotating shaft from rotating and causing the camera body to deviate in angle. When the camera reaches its outermost edge, the inclined structure at the end of the guide block abuts against a gear, causing the gear to move upwards along the outer wall of the rotating shaft. This releases the limiting component from restricting the rotating shaft, and the drive component stops working. A meshing component then drives the gear to rotate, resulting in a small rotation of the gear. This rotation of the gear, via the connecting plate, causes the camera body to rotate, thus increasing the camera's field of view.

[0011] 2. Beneficial effects:

[0012] Existing technologies can freely move to adjust their position, expanding the monitoring range and meeting the growing needs of enterprises. However, existing technologies suffer from structural complexity due to the multiple structures used to move only the camera body. This solution addresses this by using a drive component to facilitate left and right movement of the camera body, thereby increasing its field of view. A limiting component prevents the rotating shaft from rotating, thus avoiding deviations in the field of view caused by external forces. Finally, a meshing component drives a gear when the camera body reaches the edge, which in turn rotates the connecting plate and camera body via the shaft, further increasing the camera's field of view.

[0013] Preferably, the driving assembly includes an intermittent motor fixedly connected to the outer wall of the cavity. A lead screw is fixedly connected to the output end of the intermittent motor, and the end of the lead screw is rotatably connected to the side wall of the cavity. A movable block is threadedly connected to the outer wall of the lead screw, and the top of the movable block is slidably connected to the top of the inner side wall of the cavity. The bottom of the movable block is rotatably connected to the top of the rotating shaft. When this device is in use, the intermittent motor is started first, which drives the lead screw to rotate. During the rotation of the lead screw, the movable block slides along the outer wall of the lead screw, thereby driving the rotating shaft to move. During the movement of the rotating shaft, the connecting plate and the camera body move, thereby achieving the purpose of adjusting the position of the camera body and increasing the field of view of the camera body.

[0014] Preferably, the limiting component includes limiting rods symmetrically fixedly connected to the bottom of the gear, a limiting hole is opened on the top of the slider and the limiting hole is adapted to the limiting rod, a fixing plate is fixedly connected to the outer wall of the rotating shaft, a spring is sleeved on the outer wall of the rotating shaft, the lower end of the spring is fixedly connected to the top of the gear, and the top of the spring is fixedly connected to the bottom of the fixing plate. During the process of the moving block driving the rotating shaft to move, the limiting rod is located inside the limiting hole to prevent the rotating shaft and the moving block from rotating during the movement of the camera body, which would cause the camera angle to deviate and make it impossible to monitor the power grid video surveillance. When the moving block moves to the edge, the inclined structure at the end of the guide block abuts against the gear, causing the gear to move upward along the outer wall of the rotating shaft. During the upward movement of the gear, the limiting rod is driven to disengage from the limiting hole. During this process, the spring is compressed, so that the rotating shaft is unrestricted at this moment.

[0015] Preferably, the distance between the two limiting rods is much smaller than the distance between the two guide blocks, to prevent the two limiting rods from contacting the two guide blocks during gear rotation.

[0016] Preferably, the meshing assembly includes an electric telescopic rod fixedly connected to the inner wall of the cavity. The output end of the electric telescopic rod is fixedly connected to a rack plate, which is slidably connected to the inner wall of the cavity. The rack plate is adapted to the gear. When the moving block moves to the outermost edge, the intermittent motor stops working, and the electric telescopic rod is started. The electric telescopic rod drives the rack plate to move. During the movement of the rack plate, the gear is driven to rotate, which in turn drives the connecting plate to rotate through the rotating shaft, thereby achieving the purpose of rotating the angle of the camera body and increasing the field of view of the camera body.

[0017] Preferably, the electric telescopic rod is electrically linked to the intermittent motor. When the intermittent motor is working, the electric telescopic rod is in the closed state, and when the intermittent motor is off, the electric telescopic rod is in the working state.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] like Figure 1-5As shown, a monitoring device for a power grid video surveillance system includes a rectangular block 1, a camera body 2, and a cavity 5. A rectangular groove 4 is formed at the bottom of the cavity 5. A slider 9 is slidably connected to the inner wall of the rectangular groove 4. A rotating shaft 13 is rotatably connected through the top of the slider 9. A connecting plate 3 is fixedly connected to the lower end of the rotating shaft 13, and the bottom of the connecting plate 3 is fixedly connected to the top of the camera body 2. A gear 15 is slidably connected to the outer wall of the rotating shaft 13. Guide blocks 8 are symmetrically fixedly connected to the inner wall of the cavity 5, and the ends of the guide blocks 8 have an inclined structure. A driving assembly is fixedly connected to the side wall of the cavity 5. The driving assembly includes an intermittent motor 10 fixedly connected to the outer wall of the cavity 5, and a lead screw 6 is fixedly connected to the output end of the intermittent motor 10. The end of the lead screw 6 is rotatably connected to the side wall of the cavity 5. A moving block 11 is threadedly connected to the outer side wall of the lead screw 6, and the top of the moving block 11 is slidably connected to the top of the inner side wall of the cavity 5. The bottom of the moving block 11 is rotatably connected to the top of the rotating shaft 13. First, the intermittent motor 10 is started, which drives the lead screw 6 to rotate. During the rotation of the lead screw 6, the moving block 11 is driven to slide along the outer side wall of the lead screw 6, thereby driving the rotating shaft 13 to move through the moving block 11. During the movement of the rotating shaft 13, the connecting plate 3 and the camera body 2 are moved, thereby achieving the purpose of adjusting the position of the camera body 2 and increasing the field of view of the camera body 2. A limit component is provided at the bottom of the gear 15. The limit component includes... The device includes a limiting rod 17 symmetrically fixedly connected to the bottom of the gear 15, a limiting hole 18 on the top of the slider 9 that matches the limiting rod 17, a fixing plate 14 fixedly connected to the outer wall of the rotating shaft 13, and a spring 16 sleeved on the outer wall of the rotating shaft 13. The lower end of the spring 16 is fixedly connected to the top of the gear 15, and the top of the spring 16 is fixedly connected to the bottom of the fixing plate 14. During the movement of the rotating shaft 13 driven by the moving block 11, the limiting rod 17 is located inside the limiting hole 18 to prevent rotation between the rotating shaft 13 and the moving block 11 during the movement of the camera body 2, which would cause the angle of the camera body 2 to shift and prevent monitoring of the power grid video surveillance. When the moving block 11 moves to the edge, it is guided by a guide block. The inclined structure at the end of the 8-axis abuts against the gear 15, causing the gear 15 to move upward along the outer wall of the rotating shaft 13. During the upward movement of the gear 15, the limiting rod 17 is disengaged from the limiting hole 18. During this process, the spring 16 is compressed, so that the rotating shaft 13 is unrestricted and can rotate through the connecting disc 3 attached to the rotating shaft 13. A meshing assembly is fixedly connected to the inner wall of one end of the cavity 5. The meshing assembly includes an electric telescopic rod 12 fixedly connected to the inner wall of the cavity 5. A rack plate 7 is fixedly connected to the output end of the electric telescopic rod 12. The rack plate 7 is slidably connected to the inner wall of the cavity 5, and the rack plate 7 is adapted to the gear 15. When the moving block 11 moves to the outermost edge, the intermittent motor 10 stops working and the electric telescopic rod 12 is activated.The electric telescopic rod 12 moves the rack plate 7, which in turn drives the gear 15 to rotate. This rotation, in turn, drives the connecting plate 3 to rotate via the rotating shaft 13, thereby achieving the purpose of rotating the camera body 2 and increasing its field of view.

[0026] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0027] In use, this device first starts by activating the intermittent motor 10, which drives the lead screw 6 to rotate. During this rotation, the moving block 11 slides along the outer wall of the lead screw 6, thereby moving the rotating shaft 13. This movement of the rotating shaft 13 then moves the connecting plate 3 and the camera body 2, thus adjusting the position of the camera body 2 and increasing its field of view. During the movement of the rotating shaft 13, the limiting rod 17 is positioned inside the limiting hole 18 to prevent rotation between the rotating shaft 13 and the moving block 11, which could cause the camera body 2 to shift angle and prevent proper power grid video monitoring. The system monitors the movement of the camera body 2. When the moving block 11 moves to the edge, it abuts against the gear 15 through the inclined structure at the end of the guide block 8, causing the gear 15 to move upward along the outer wall of the rotating shaft 13. During the upward movement of the gear 15, the limiting rod 17 is disengaged from the limiting hole 18. During this process, the spring 16 is compressed, so that the rotating shaft 13 is unrestricted. When the moving block 11 moves to the outermost edge, the intermittent motor 10 stops working and the electric telescopic rod 12 is activated. The electric telescopic rod 12 drives the rack plate 7 to move. During the movement of the rack plate 7, the gear 15 is driven to rotate, which in turn drives the connecting plate 3 to rotate through the rotating shaft 13, thereby achieving the purpose of rotating the camera body 2 at an angle and increasing the field of view of the camera body 2.
