Description

Technical Field

[0001] This invention relates to the field of cable monitoring technology, and in particular to a low-voltage cable anti-theft monitoring device. Background Technology

[0002] A cable is a device for transmitting electrical energy or signals, typically composed of several or groups of conductors. Due to their high cost, cables are frequently targeted for theft, especially in outdoor locations such as low-voltage boxes and distribution rooms. To protect these cables, anti-theft monitoring equipment is usually installed to monitor them.

[0003] There are two main types of existing monitoring methods: one is to install cameras in concealed corners of the box, and the other is to install cameras in the external environment, such as on utility poles or trees. Because the former is installed inside the box, the direction of damage caused by criminals when stealing is uncertain, making it difficult to guarantee the monitoring effect and easily resulting in the inability to capture the theft footage. Therefore, the method of installing cameras on the outside is usually adopted for monitoring, which can not only capture the entire environment of the low-voltage box, but also serve as a warning.

[0004] Existing monitoring equipment installed in the external environment mainly suffers from the following problems:

[0005] 1. Because the monitoring equipment is installed on trees or utility poles, it is inconvenient to install and maintain. In case of failure, cranes and other equipment are required, which is quite inconvenient.

[0006] 2. Because surveillance equipment is difficult to conceal, criminals will use floating objects such as balloons to obstruct it, making it difficult for monitoring personnel to determine the reason for the obstruction and affecting the monitoring effect.

[0007] 3. Because the cameras are installed on the side of trees or utility poles, the trees or poles may obstruct the view, resulting in low utilization of the cameras themselves. They can only monitor a limited area, requiring additional cameras for monitoring, which increases the cost of use.

[0008] Therefore, there is an urgent need for a low-voltage cable anti-theft monitoring device to solve the monitoring problem of outdoor low-voltage cables. Summary of the Invention

[0009] The purpose of this invention is to provide a low-voltage cable anti-theft monitoring device with a walking function and the ability to increase the monitoring angle.

[0010] The technical solution adopted in this invention is as follows:

[0011] A low-voltage cable anti-theft monitoring device includes a ring and a mounting rod. The ring has a connecting cavity extending through its center along its axis, allowing the mounting rod to pass through. A transmission cavity is located in the center of the ring, open at one end near the connecting cavity. A transmission gear ring rotatably rotates within the transmission cavity, its axis of rotation coaxial with the ring. Transmission teeth are located on the inner wall of the transmission gear ring. A power cavity is located within the ring, housing a drive motor. A drive gear, meshing with the transmission teeth, is connected to the output shaft of the drive motor. Multiple transmission gears are also located within the ring, symmetrically arranged along the ring's axis, and rotatably connected to the ring. Each transmission gear has two operating states: a first state where it meshes with the transmission gear ring, and a second state where it does not mesh with the transmission gear ring. A climbing device is also located within the ring. The device includes multiple climbing wheels, the axis of which is perpendicular to the axis of the ring sleeve. Each climbing wheel contacts the mounting rod, and the axes of the multiple climbing wheels are respectively connected to multiple transmission gears. A switching device is provided within the ring sleeve to control the transmission gears between a first working state and a second working state. A camera assembly is also provided below the ring sleeve. An arc groove is also provided within the ring sleeve, and a connecting rod is slidably disposed within the arc groove. One end of the connecting rod is connected to the camera assembly, and the other end is free. A track groove is also provided on the inner wall of the arc groove, and a track protrusion on the connecting rod mates with the track groove. A locking device is provided between the transmission gear ring and the connecting rod to connect the connecting rod and the transmission gear ring, thereby driving the connecting rod to slide along the track groove. A control cavity is also provided within the ring sleeve, containing a controller and a battery. The controller is electrically connected to the drive motor, the camera assembly, and the battery.

[0012] In this design, the mounting pole is a tree trunk or utility pole, while the ring is the main body of the device. The connecting cavity allows the mounting pole to pass through. In actual use, the ring is designed as a detachable structure for ease of use. The transmission cavity in the middle of the ring, with its internal transmission gear ring and transmission teeth, transmits power. The drive motor and drive gears drive the transmission gear ring to rotate. Multiple transmission gears and corresponding climbing wheels, when the transmission gear ring rotates, drive the climbing wheels to rotate, causing the entire ring to shift vertically along the mounting pole, thus facilitating the installation and maintenance of the equipment. In actual use, an anti-slip layer is added to the surface of the climbing wheel to ensure smooth movement. The switching device controls the position of the ring. When the pole reaches a suitable height, the transmission between the gear ring and the climbing wheel is disconnected. When maintenance is required, the transmission between the gear ring and the climbing wheel is reconnected, thus preventing mistaken connection. The arc groove and the connecting rod sliding within it, the camera assembly located below the connecting rod, and the rail protrusion on the connecting rod allow the monitoring assembly to slide along the arc groove, providing the camera assembly with a wider monitoring range and angle. To avoid external obstruction, a locking device is used to connect the connecting rod to the transmission gear ring. This locking connection allows control of the camera component to be disconnected once it reaches the edge of the arc groove. This serves two purposes: firstly, it prevents the overall rotation angle from exceeding 360°, thus avoiding wiring tangling issues; secondly, it allows the drive structure to be positioned at the arc notch, thereby improving transmission efficiency (the motor's power output is directly connected to the transmission gear ring). Simultaneously, it minimizes the size of the annular groove, reducing production costs. The placement of the controller and battery within the control cavity is used to control the various functional components. In practical applications, the controller typically needs to be equipped with a Bluetooth signal transmission module for remote transmission of monitoring signals and remote control. As can be seen from the above, this solution not only has a climbing structure that allows free control of the equipment's upward and downward movement, facilitating disassembly and maintenance, but also allows for large-angle adjustment of the camera component's position. Combined with the rotation of the camera component itself, it can monitor various angles around the mounting rod, greatly improving the utilization rate of the device. When encountering obstructions, the position of the camera component can also be adjusted to avoid monitoring the obstructions, making it highly practical.

[0013] Preferably, the switching device includes an electric telescopic rod electrically connected to the controller. The electric telescopic rod is disposed near the upper surface of the ring sleeve. A switching cavity is disposed inside the ring sleeve, and the switching cavity is disposed above the transmission cavity. The shaft of the climbing wheel passes through the switching cavity and is provided with a first helical gear. The shaft at the upper end of the transmission gear passes through the switching cavity and is provided with a second helical gear. The lower part of the electric telescopic rod passes through the switching cavity and is provided with a first movable rod. The shaft at the upper end of the transmission gear extends horizontally and is provided with a push block. The free end of the first movable rod is in contact with the push block. A plurality of auxiliary cavities are connected below the transmission cavity. The auxiliary cavities are T-shaped in cross-section. The transmission gear and the shaft at the lower end of the transmission gear are adapted to fall into the auxiliary cavities when shifting downward. A compression spring is also provided in the auxiliary cavity. One end of the compression spring is connected to the stepped surface of the auxiliary cavity, and the other end of the compression spring is in contact with the bottom surface of the transmission gear. The compression spring is arranged around the shaft at the lower end of the transmission gear. The electric telescopic rod is designed to control the downward offset of the transmission gear through the cooperation of the first movable rod and the push block, thereby controlling the disengagement of the first and second helical gears. At the same time, it controls the disengagement of the transmission gear and the transmission gear ring, achieving the purpose of cutting off. The auxiliary cavity compression spring can push the transmission gear upward through the elastic force of the spring when the first movable rod retracts, thereby controlling the engagement of the first and second helical gears. The combination of the two can control the opening and closing of the power transmission between the transmission gear ring and the climbing wheel. The structure is simple and easy to use.

[0014] Preferably, the bottom end of the auxiliary cavity extends toward the connecting cavity and is provided with a locking cavity. A locking rod is slidably disposed in the locking cavity. A locking block is disposed on the locking rod toward the connecting cavity. A tension spring is also disposed in the locking cavity. One end of the tension spring is connected to the locking cavity, and the other end of the tension spring is connected to the locking block. A locking arc surface is provided at the end of the locking rod away from the locking block. A downward pushing arc surface is provided at the free end of the lower shaft of the transmission gear. The downward pushing arc surface is adapted to push the locking arc surface during the downward movement so that the locking block slides toward the mounting rod. The locking rod and locking block inside the locking cavity can push the locking arc surface when the downward-pushing arc surface moves downward (i.e., the transmission gear moves downward), so that the locking block presses against the mounting rod, thereby fixing the ring in the current position. When the transmission gear moves upward, it can retract under the action of the tension spring. At this time, the up and down displacement of the ring can be freely controlled. This not only ensures the positioning effect in the fixed state, but also prevents the up and down displacement of the ring from being caused by the rotation of the transmission gear ring.

[0015] Preferably, the locking block is arc-shaped on the side near the mounting rod, and a locking anti-slip layer is also provided on the locking block. The arc-shaped locking block and the locking anti-slip layer can increase the contact area between the locking block and the mounting rod, and at the same time increase the friction, further ensuring the positioning effect.

[0016] Preferably, the electric telescopic rod is a bidirectional telescopic rod, with a second movable rod above it. A solar panel electrically connected to the battery is also located above the ring sleeve, and the second movable rod is connected to the solar panel. The solar panel allows the battery to be charged during the day, reducing the frequency of battery maintenance and replacement. The bidirectional telescopic rod allows the solar panel to be pushed upwards while the ring sleeve is positioned, improving conversion efficiency. Furthermore, the consistency between the solar panel's angle adjustment and the ring sleeve's fixation reduces the need for a power unit, lowering production costs and enhancing practicality.

[0017] Preferably, a first hinge block and a second hinge block are provided below the solar panel, and a support rod is hinged above the ring. The first hinge block is connected to the free end of the support rod, and the second hinge block is connected to the free end of the second movable rod. The arrangement of the first and second hinge blocks and the support rod allows for control of the angle offset of the solar panel in cooperation with the second movable rod, thereby maximizing the reception of solar radiation energy and improving the power generation efficiency of the solar panel.

[0018] Preferably, a locking groove is provided below the transmission gear ring, and the locking device includes an elastic locking block disposed at the top of the connecting rod, the elastic locking block being configured to cooperate with the locking groove. The locking groove and elastic locking block are configured such that when the locking groove moves above the connecting rod, the elastic locking block extends, enabling the connecting rod and camera assembly to slide along the arc groove. When it reaches the end position of the arc groove, the elastic locking block retracts under the action of a horizontal thrust at the end, disengaging from the locking groove, ensuring effective operation.

[0019] Preferably, the connecting rod is further provided with a foolproof block, the horizontal cross-sectional dimension of which is matched with the arc groove. The foolproof block prevents the connecting rod from rotating along its own axis, restricts its degree of freedom, and ensures the effectiveness of use.

[0020] Preferably, a wire groove is provided within the annular groove, connecting the control cavity and the arc groove. A reset wheel is provided within the control cavity, and a connecting wire is wound around the reset wheel. One end of the connecting wire is connected to the controller, and the other end passes through the wire groove and connects to the camera assembly. The camera assembly and the controller are electrically connected via the connecting wire. The connecting wire on the reset wheel extends the connecting rod as it slides away from the opening of the arc groove, and automatically retracts it when it approaches, ensuring the connecting wire remains taut and preventing cable tangling, thus guaranteeing optimal performance.

[0021] Preferably, the inner wall of the transmission cavity is provided with multiple ball grooves, and supporting balls are disposed in the ball grooves, with the supporting balls contacting the transmission gear ring. The ball grooves not only support and position the transmission gear ring, ensuring its stability, but also convert the sliding friction between the transmission gear ring and the inner wall of the transmission cavity into rolling friction, reducing friction and extending the service life of the device.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] In this invention, the climbing wheel, transmission gear, transmission gear ring, and drive motor work together to freely control the upward and downward movement of the equipment, facilitating disassembly, assembly, and maintenance. Furthermore, the design, through the connection rod connected to the transmission gear ring and the camera assembly at the end of the connecting rod, allows for large-angle adjustment of the camera assembly's position. Combined with the rotation of the camera assembly itself, it enables monitoring of various angles around the mounting rod, significantly improving the device's utilization rate. Even when obstructed by foreign objects, the camera assembly's position can be adjusted to avoid monitoring those objects. This invention is highly practical and suitable for widespread use.

[0024] 2. In this invention, by setting up an electric telescopic rod and cooperating with the first movable rod and the push block, the transmission gear is controlled to shift downward, thereby controlling the first and second helical gears to disengage. At the same time, the transmission gear and the transmission gear ring are controlled to disengage, achieving the purpose of cutting off. The setting of the compression spring in the auxiliary cavity allows the transmission gear to be pushed upward by the elastic force of the compression spring when the first movable rod is retracted, thereby controlling the first and second helical gears to mesh. The combination of the two can control the opening and closing of the power transmission between the transmission gear ring and the climbing wheel. The structure is simple and easy to use.

[0025] 3. In this invention, by setting the locking rod and locking block in the locking cavity, when the downward-pushing arc surface moves downward, it can push the locking arc surface, so that the locking block presses against the mounting rod, thereby fixing the ring sleeve in the current position. When the transmission gear moves upward, it can be retracted under the action of the tension spring. At this time, the up and down displacement of the ring sleeve can be freely controlled, which not only ensures the positioning effect in the fixed state, but also prevents the up and down displacement of the ring sleeve from being caused by the rotation of the transmission gear ring.

[0026] 4. In this invention, the solar panel, the first and second hinge blocks, and the support rod enable the battery to be charged during the day, thereby reducing the frequency of battery maintenance and replacement. With the bidirectional telescopic rod, the solar panel can be pushed up while the ring is positioned to maximize the reception of solar radiation energy and improve the power generation efficiency of the solar panel. Furthermore, due to the consistency between the angle adjustment of the solar panel and the fixing of the ring, the power unit can be reduced, production costs can be lowered, and the invention is highly practical.

[0027] 5. In this invention, by setting the connecting line on the reset wheel, when the connecting rod slides away from the opening of the wire groove along the arc groove, the connecting line is pulled out and automatically retracted by the reset wheel when it gets close, ensuring that the connecting line is always in a taut state, avoiding cable tangling and ensuring the effect of use.

[0040] like Figure 1-7 As shown, a low-voltage cable anti-theft monitoring device includes a ring sleeve 1 and a mounting rod 2. The ring sleeve 1 has a connecting cavity 3 extending through its center along its axis, allowing the mounting rod 2 to pass through. A transmission cavity 4 is located in the center of the ring sleeve 1, opening at one end near the connecting cavity 3. A transmission gear ring 5 is rotatably mounted within the transmission cavity 4, its rotation axis coaxial with the ring sleeve 1. Transmission teeth 6 are provided on the inner sidewall of the transmission gear ring 5. A power cavity 7 is located within the ring sleeve 1, housing a drive motor 8. A drive gear 9, meshing with the transmission teeth 6, is connected to the output shaft of the drive motor 8. Multiple transmission gears 10 are also provided within the ring sleeve 1, symmetrically arranged along the axis of the ring sleeve 1, and rotatably connected to the ring sleeve 1. Each transmission gear 10 has two operating states.

[0041] First working state: The transmission gear 10 is engaged with the transmission gear ring 5;

[0042] Second working state: The transmission gear 10 is not engaged with the transmission gear ring 5;

[0043] The ring 1 is also equipped with a climbing device, which includes multiple climbing wheels 11. The axis of the climbing wheel 11 is perpendicular to the axis of the ring 1. The climbing wheel 11 is in contact with the mounting rod 2. The axis of the multiple climbing wheels 11 is respectively connected to multiple transmission gears 10. The ring 1 is equipped with a switching device, which is used to control the transmission gears 10 to switch between the first working state and the second working state. A camera assembly 12 is also provided below the ring 1. The ring 1 is also equipped with an arc groove 13. A connecting rod 14 is slidably arranged in the arc groove 13. One of the connecting rods 14... One end is connected to the camera assembly 12, and the other end of the connecting rod 14 is freely disposed. A track groove 15 is also provided on the inner wall of the arc groove 13. A track protrusion 16 that cooperates with the track groove 15 is provided on the connecting rod 14. A locking device is provided between the transmission gear ring 5 and the connecting rod 14. The locking device is suitable for connecting the connecting rod 14 and the transmission gear ring 5 to drive the connecting rod 14 to slide along the track groove 15. A control cavity 17 is also provided inside the ring sleeve 1. A controller 18 and a battery 19 are provided inside the control cavity 17. The controller 18 is electrically connected to the drive motor 8, the camera assembly 12 and the battery 19.

[0044] Specifically, such as Figure 1 ,2 As shown in Figures 3, 5, and 7, the switching device includes an electric telescopic rod 20 electrically connected to the controller 18. The electric telescopic rod 20 is disposed near the upper surface of the ring sleeve 1. A switching cavity 21 is disposed inside the ring sleeve 1, and the switching cavity 21 is disposed above the transmission cavity 4. The shaft of the climbing wheel 11 passes through the switching cavity 21 and is provided with a first helical gear 22. The shaft at the upper end of the transmission gear 10 passes through the switching cavity 21 and is provided with a second helical gear 23. The lower part of the electric telescopic rod 20 passes through the switching cavity 21 and is provided with a first movable rod 24. The shaft at the upper end of the transmission gear 10... A push block 25 is provided on the horizontally extended rod. The free end of the first movable rod 24 is in contact with the push block 25. A plurality of auxiliary cavities 26 are provided below the transmission cavity 4. The cross-section of the auxiliary cavity 26 is T-shaped. The transmission gear 10 and the shaft at the lower end of the transmission gear 10 are adapted to fall into the auxiliary cavity 26 when deflecting downward. A compression spring 27 is also provided in the auxiliary cavity 26. One end of the compression spring 27 is connected to the stepped surface of the auxiliary cavity 26, and the other end of the compression spring 27 is in contact with the bottom surface of the transmission gear 10. The compression spring 27 is arranged around the shaft at the lower end of the transmission gear 10.

[0045] Specifically, such as Figure 1 , 2 As shown in Figures 3, 5, and 7, the bottom end of the auxiliary cavity 26 extends toward the connecting cavity 3 and is provided with a locking cavity 28. A locking rod 29 is slidably disposed in the locking cavity 28. A locking block 30 is disposed on the locking rod 29 toward the connecting cavity 3. A tension spring 31 is also disposed in the locking cavity 28. One end of the tension spring 31 is connected to the locking cavity 28, and the other end of the tension spring 31 is connected to the locking block 30. A locking arc surface 32 is provided at the end of the locking rod 29 away from the locking block 30. A downward pushing arc surface 33 is provided at the free end of the lower shaft of the transmission gear 10. The downward pushing arc surface 33 is suitable for pushing the locking arc surface 32 during the downward movement so that the locking block 30 slides toward the mounting rod 2.

[0046] Specifically, such as Figure 1 , 2 As shown in Figures 3, 5, and 7, the locking block 30 is arranged in an arc shape on the side near the mounting rod 2, and a locking anti-slip layer 34 is also provided on the locking block 30.

[0047] Specifically, such as Figure 1 , 2 As shown, the electric telescopic rod 20 is a bidirectional telescopic rod. A second movable rod 35 is provided above the electric telescopic rod 20. A solar panel 36 electrically connected to the battery 19 is also provided above the ring sleeve 1. The second movable rod 35 is connected to the solar panel 36.

[0048] Specifically, such as Figure 1 , 2 As shown, a first hinge block 37 and a second hinge block 38 are provided below the solar panel 36, and a support rod 39 is also hinged above the ring 1. The first hinge block 37 is connected to the free end of the support rod 39, and the second hinge block 38 is connected to the free end of the second movable rod 35.

[0049] Specifically, such as Figure 1 , 2 As shown in Figure 5, a locking groove 40 is provided below the transmission gear ring 5. The locking device includes an elastic locking block 41 disposed at the top of the connecting rod 14. The elastic locking block 41 is configured to cooperate with the locking groove 40.

[0050] Specifically, such as Figure 2 , 4 As shown in Figure 5, the connecting rod 14 is also provided with a foolproof block 42, and the horizontal cross-sectional dimension of the foolproof block 42 is configured to match the arc groove 13.

[0051] Specifically, such as Figure 1 , 2 As shown in Figures 5 and 6, a wire groove 43 is provided in the annular groove. The wire groove 43 connects the control cavity 17 and the arc groove 13. A reset wheel 44 is provided in the control cavity 17. A connecting wire 45 is wound on the reset wheel 44. One end of the connecting wire 45 is connected to the controller 18, and the other end of the connecting wire 45 passes through the wire groove 43 and is connected to the camera assembly 12. The camera assembly 12 and the controller 18 are electrically connected through the connecting wire 45.

[0052] Specifically, such as Figure 1 , 2 As shown in Figures 4 and 5, a plurality of ball grooves 46 are provided on the inner wall of the transmission cavity 4, and a supporting ball 47 is provided in the ball groove 46. The supporting ball 47 is in contact with the transmission gear ring 5.

[0053] During installation, simply place the ring 1 onto the bottom of the mounting rod 2 (in practical applications, the ring 1 can be made into a detachable structure for easy placement; this is a conventional technique, and the specific implementation method is not shown in the solution). Then, control the drive motor 8 to start (rotate forward). The drive motor 8 will drive the transmission gear ring 5 to rotate through the drive gear 9. (During this process, the camera component 12 will also rotate along the arc groove 13 under the action of the connecting rod 14, which does not affect the operation of the device). This will drive the transmission gear 10 to rotate, and through the transmission of the first and second helical gears 23, drive the climbing wheel. Rotate 11 to drive the ring sleeve 1 to move upward along the mounting rod 2. When it moves to the appropriate position, the controller 18 controls the electric telescopic rod 20 (bidirectional telescopic rod) to extend. The first movable rod 24 will drive the transmission gear 10 to deflect through the push block 25, so that the first and second helical gears 23 disengage. The transmission gear 10 and the transmission gear ring 5 disengage. At the same time, the downward pushing arc surface 33 pushes the locking arc surface 32, so that the locking block 30 is in close contact with the mounting rod 2. At this time, the second movable rod 35 also extends, driving the solar energy plate to rotate to the appropriate angle, thus completing the installation.

[0054] During use, when it is necessary to adjust the position of the camera assembly 12, simply control the drive motor 8 to rotate so that the elastic block 41 engages with the engagement slot 40 (this process can be achieved by slowly rotating the drive motor 8; after engagement, the camera direction will deflect, and the observer can intuitively understand that this is the engagement state). Then, control the drive motor 8 to rotate forward or backward as needed until the camera assembly 12 is adjusted to the appropriate direction.

[0055] When equipment maintenance is required, simply retract the electric telescopic rod 20 and the first movable rod 24. The transmission gear 10 will move upward under the action of the compression spring 27, causing the first and second helical gears 23 to mesh. The transmission gear 10 will mesh with the transmission gear ring 5. At the same time, the locking block 30 will retract into the locking cavity 28 under the action of the tension spring 31. Then, control the drive motor 8 to turn on (forward rotation). The drive motor 8 will drive the transmission gear ring 5 to rotate through the drive gear 9. (During this process, the camera assembly 12 will also rotate along the arc groove 13 under the action of the connecting rod 14, which will not affect the operation of the device.) This will drive the transmission gear 10 to rotate. Through the transmission of the first and second helical gears 23, the climbing wheel 11 will rotate in the opposite direction, thereby driving the entire ring sleeve 1 to move downward along the mounting rod 2. When it moves to a suitable position (for easy maintenance), turn off the drive motor 8. After maintenance, repeat the installation operation.

[0056] As can be seen from the above description, the climbing wheel 11 of this application, together with the transmission gear 10, the transmission gear ring 5, and the drive motor 8, can freely control the upward and downward movement of the equipment, facilitating disassembly, assembly, and maintenance. In addition, through the connection rod 14 connected to the transmission gear ring 5 and the camera assembly 12 at the end of the connection rod 14, the position of the camera assembly 12 can be adjusted at a large angle. With the rotation of the camera assembly 12 itself, it can monitor various angles around the mounting rod 2, greatly improving the utilization rate of the device. When encountering foreign objects that obstruct the view, the position of the camera assembly 12 can also be adjusted to avoid the foreign objects during monitoring.
