Description

Technical Field

[0001] The invention relates to the technical field of cable monitoring, and in particular to a low-voltage cable theft-proof monitoring device. Background Art

[0002] Cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. Due to the high cost of cables, they are often the target of theft by criminals, especially those installed in outdoor weak current boxes and distribution rooms. In order to protect the cables, anti-theft monitoring equipment is usually required to monitor the cables.

[0003] There are two main existing monitoring methods. One is to install a camera in a hidden corner of the box, and the other is to install a camera in an external environment, such as a telephone pole or a tree. The former is installed inside the box, and the direction of destruction by criminals when stealing is uncertain, making it difficult to ensure the monitoring effect, and it is easy to fail to capture the theft scene. Therefore, it is usually necessary to install a camera outside for monitoring, which can not only capture the environment of the entire weak current box, but also serve as a warning.

[0004] The existing monitoring equipment set up in the external environment mainly has the following problems: 1. Since the monitoring equipment is installed on trees or electric poles, it is not easy to install and maintain. When a failure occurs, it requires the cooperation of cranes and other equipment, which is inconvenient.

[0005] 2. Since monitoring equipment is difficult to hide, criminals will use floating obstructions such as balloons to cover it. It is difficult for monitoring personnel to determine the cause of the obstruction, which affects the monitoring effect.

[0006] 3. Since the camera is set on the side of a tree or a utility pole, there will be obstruction by the tree or the utility pole, which makes the utilization rate of the camera itself low and can only monitor a limited area. Additional cameras are needed for monitoring, which increases the cost of use.

[0007] Therefore, there is an urgent need for a weak-current cable anti-theft monitoring device to solve the monitoring problem of outdoor weak-current cables. Summary of the invention

[0008] The purpose of the present invention is to provide a weak-current cable anti-theft monitoring device with a walking function and capable of increasing the monitoring angle.

[0009] The technical solution adopted by the present invention is as follows: A low-voltage cable theft-proof monitoring device comprises a ring sleeve and a mounting rod, characterized in that a connecting cavity is provided in the middle position of the ring sleeve along the axis of the ring sleeve, and the connecting cavity is suitable for the mounting rod to pass through, wherein: a transmission cavity is provided in the middle position of the ring sleeve, and the transmission cavity is provided with an opening at one end close to the connecting cavity, a transmission gear ring is rotatably provided in the transmission cavity, the rotation axis of the transmission gear ring is coaxially provided with the ring sleeve, and a transmission tooth is provided on the inner side wall of the transmission gear ring; a power cavity is provided in the ring sleeve, a driving motor is provided in the power cavity, and a driving gear meshing with the transmission tooth is provided on the output shaft of the driving motor for transmission connection; a transmission gear is also provided in the ring sleeve, and a plurality of transmission gears are provided, and the plurality of transmission gears are axially symmetrically provided along the axis of the ring sleeve, and the transmission gear is rotationally connected with the ring sleeve; the transmission gear comprises at least two working states: a first working state: the transmission gear meshes with the transmission gear ring; a second working state: the transmission gear does not mesh with the transmission gear ring; a climbing rod device is also provided in the ring sleeve, and the climbing rod device is ... The rod device comprises a plurality of climbing rod wheels, the axis of the climbing rod wheel rotating shaft is arranged perpendicularly to the axis of the ring sleeve, the climbing rod wheel is arranged in contact with the mounting rod, and the rotating shafts of the plurality of climbing rod wheels are respectively connected to the plurality of transmission gears; a switching device is arranged in the ring sleeve, and the switching device is suitable for controlling the climbing rod device to switch between the first state and the second state; a camera assembly is also arranged below the ring sleeve, and an arc groove is also arranged in the ring sleeve, and a connecting rod is slidably arranged in the arc groove, one end of the connecting rod is connected to the camera assembly, and the other end of the connecting rod is freely arranged, and a track groove is also arranged on the inner wall of the arc groove, and a track protrusion cooperating with the track groove is arranged on the connecting rod; a clamping device is arranged between the transmission gear ring and the connecting rod, and the clamping device is suitable for connecting the connecting rod and the transmission gear ring to drive the connecting rod to slide along the track groove; a control chamber is also arranged in the ring sleeve, and a controller and a battery are arranged in the control chamber, and the controller is electrically connected to the drive motor, the camera assembly and the battery.

[0010] In the scheme, the mounting pole is a pole such as a tree or a telephone pole, and the ring sleeve is the main body of the device. The connecting cavity is provided for the mounting pole to pass through. In actual use, the ring sleeve is provided as a detachable structure for easy use. The transmission cavity in the middle position of the ring sleeve, the transmission gear ring and the transmission teeth therein are provided for transmitting power. The drive motor and the drive gear are provided for driving the transmission gear ring to rotate. The plurality of transmission gears and the corresponding plurality of climbing rod wheels can drive the climbing rod wheels to rotate when the transmission gear ring rotates, thereby driving the ring sleeve as a whole to deviate up and down along the mounting pole, thereby facilitating the installation and maintenance of the equipment. In actual use, an anti-skid layer will be added to the surface of the climbing wheel to ensure the movement effect. The switching device is used to control the position of the ring sleeve. When it runs to a suitable height, the transmission of the transmission gear ring and the climbing wheel is disconnected. When maintenance is required, the transmission of the transmission gear ring and the climbing wheel is reconnected to prevent fooling. The arc groove and the connecting rod sliding in the arc groove, the camera assembly arranged under the connecting rod, and the track protrusion on the connecting rod enable the monitoring assembly to slide along the arc groove, thereby providing the camera assembly with a larger monitoring range and monitoring angle. In order to avoid external obstruction, the setting of the locking device is used to connect the connecting rod with the transmission gear ring. Through the locking connection, the control of the camera assembly can be disconnected when it runs to the edge of the arc groove. First, it is used to avoid the overall rotation angle exceeding 360°, which will cause wiring and line entanglement problems. Secondly, the driving structure can be set at the gap of the arc to improve the transmission efficiency (the motor power output is directly connected to the transmission gear ring). At the same time, the size of the ring groove is minimized to reduce the production cost. The setting of the control cavity controller and the battery is used to control each functional part. In actual application, it is usually necessary to add signal transmission modules such as Bluetooth to the controller for remote transmission of monitoring signals and remote control. From the above, it can be seen that this solution not only has a climbing structure, but also can freely control the up and down movement of the equipment, which is convenient for disassembly and maintenance. In addition, the solution can also adjust the position of the camera assembly at a large angle. With the rotation of the camera assembly itself, it can monitor all angles around the mounting rod, which greatly improves the utilization rate of the device. When encountering foreign objects blocking it, the position of the camera assembly can also be adjusted to avoid foreign object monitoring, which is highly practical.

[0011] Preferably, the switching device includes an electric telescopic rod electrically connected to the controller, the electric telescopic rod is arranged close to the upper surface of the ring sleeve, a switching cavity is arranged in the ring sleeve, the switching cavity is arranged above the transmission cavity, the rotating shaft of the climbing wheel penetrates into the switching cavity and is provided with a first bevel gear, the shaft rod at the upper end of the transmission gear penetrates into the switching cavity and is provided with a second bevel gear, the lower part of the electric telescopic rod penetrates into the switching cavity and is provided with a first movable rod, the shaft rod 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 contacted with the push block, a plurality of auxiliary cavities are connected and arranged below the transmission cavity, the cross-section of the auxiliary cavity is arranged in a "T" shape, the transmission gear and the shaft rod at the lower end of the transmission gear are suitable for falling into the auxiliary cavity when deflected downward, and a compression spring is also arranged in the auxiliary cavity, one end of the compression spring is connected to the step surface of the auxiliary cavity, and the other end of the compression spring is contacted with the bottom surface of the transmission gear, and the compression spring is arranged around the shaft rod at the lower end of the transmission gear. The setting of the electric telescopic rod can control the transmission gear to deflect downward through the cooperation of the first movable rod and the push block, thereby controlling the first and second bevel gears to be disconnected from the meshing state, and at the same time controlling the transmission gear and the transmission gear ring to be disconnected from the meshing state to achieve the purpose of cutting off. The setting of the compression spring in the auxiliary cavity can push the transmission gear upward through the elastic force of the compression spring when the first movable rod is retracted, thereby controlling the meshing of the first and second bevel 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.

[0012] Preferably, a locking cavity is provided at the bottom end of the auxiliary cavity extending toward the connecting cavity, a locking rod is slidably provided in the locking cavity, a locking block is provided toward the connecting cavity, a tension spring is also provided 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 one end of the locking rod away from the locking block, and a downward push arc surface is provided at the free end of the shaft rod at the lower end of the transmission gear, and the downward push arc surface is suitable for pushing the locking arc surface during the downward process so that the locking block slides toward the mounting rod. The arrangement of the locking rod and the locking block in the locking cavity can push the locking arc surface when the arc surface is pushed downward (that is, the transmission gear moves downward), 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 due to the rotation of the transmission gear ring.

[0013] Preferably, the locking block is arranged in an arc shape on one side close to the mounting rod, and a locking anti-skid layer is also arranged on the locking block. The arrangement of the arc-shaped locking block and the locking anti-skid layer can increase the contact surface between the locking block and the mounting rod, and at the same time increase the friction force, further ensuring the positioning effect.

[0014] Preferably, the electric telescopic rod is a two-way telescopic rod, a second movable rod is arranged above the electric telescopic rod, a solar panel electrically connected to the battery is also arranged above the ring, and the second movable rod is connected to the solar panel.

Moreover, due to the consistency of the angle adjustment of the solar panel and the fixing of the ring, the setting of the power unit can be reduced, the production cost can be reduced, and the practicability is strong.

[0015] Preferably, a first hinge block and a second hinge block are provided below the solar panel, a support rod is also hingedly provided above the ring sleeve, 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.

When the snap-fit ​​groove moves to the top of the connecting rod, the elastic snap-fit ​​block extends out, and can drive the connecting rod and the camera assembly to slide along the circular arc groove. When the snap-fit ​​groove moves to the end position of the circular arc groove, the elastic snap-fit ​​block will retract under the action of the horizontal thrust at the end, and will be separated from the snap-fit ​​groove, thereby ensuring the use effect.

[0017] Preferably, the connecting rod is also provided with an anti-fool block, and the horizontal cross-sectional size of the anti-fool block is matched with the arc groove. The setting of the anti-fool block can prevent the connecting rod from rotating along its own axis, limit its degree of freedom, and ensure the use effect.

[0018] Preferably, a wire groove is provided in the annular groove, the wire groove connects the control cavity and the circular arc groove, a reset wheel is provided in the control cavity, a connecting wire is wound around the reset wheel, one end of the connecting wire is connected to the controller, the other end of the connecting wire passes through the wire groove and is connected to the camera assembly, and the camera assembly and the controller are electrically connected through the connecting wire. The setting of the connecting wire on the reset wheel, when the connecting rod slides along the circular arc groove away from the wire groove mouth position, pulls the connecting wire to extend, and automatically retracts it through the reset wheel when it approaches, ensuring that the connecting wire is always in a tensioned state, avoiding cable entanglement, and ensuring the use effect.

[0019] Preferably, a plurality of ball grooves are provided on the inner wall of the transmission cavity, support balls are provided in the ball grooves, and the support balls are provided in contact with the transmission gear ring. The provision of the ball grooves can not only support and position the transmission gear ring to ensure its stable position, but also can convert the sliding friction between the transmission gear ring and the inner wall of the transmission cavity into rolling friction, thereby reducing friction and extending the service life of the device.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: In the present invention, through the cooperation of the climbing wheel with the transmission gear, the transmission gear ring and the driving motor, the upward and downward movement of the equipment can be freely controlled, which is convenient for disassembly, assembly and maintenance. In addition, the scheme can adjust the position of the camera assembly at a large angle through the setting of the connecting rod connected to the transmission gear ring and the camera assembly at the end of the connecting rod. With the rotation of the camera assembly itself, various angles of the circumference of the installation rod can be monitored, which greatly improves the utilization rate of the device. When encountering foreign objects blocking it, the position of the camera assembly can also be adjusted to avoid foreign object monitoring. It is highly practical and suitable for popularization and use.

[0021] 2. In the present invention, by setting the electric telescopic rod and the cooperation between the first movable rod and the push block, the transmission gear is controlled to deflect downward, thereby controlling the first and second bevel gears to be disconnected from the meshing state, and at the same time controlling the transmission gear and the transmission gear ring to be disconnected from the meshing state, so as to achieve the purpose of cutting off. The setting of the compression spring in the auxiliary cavity can push the transmission gear upward through the elastic force of the compression spring when the first movable rod is retracted, thereby controlling the meshing of the first and second bevel 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, and the structure is simple and easy to use.

[0022] 3. In the present invention, by arranging the locking rod and the locking block in the locking cavity, when the arc surface is pushed downward, the locking arc surface can be pushed so that the locking block presses against the mounting rod, thereby fixing the ring sleeve in the current position. When the transmission gear goes 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 due to the rotation of the transmission gear ring.

In the present invention, the solar panel and the arrangement of the first and second hinge blocks and the support rod can charge the battery during the day, thereby reducing the frequency of maintenance and battery replacement. With the arrangement of the two-way telescopic rod, the solar panel can be pushed up while the ring sleeve is positioned to maximize the reception of solar radiation energy and improve the power generation efficiency of the solar panel. Moreover, due to the consistency of the angle adjustment of the solar panel and the fixing of the ring sleeve, the arrangement of the power unit can be reduced, the production cost can be reduced, and the practicability is strong.

[0024] 5. In the present invention, by setting the connecting wire on the reset wheel, when the connecting rod slides along the arc groove away from the wire slot position, the connecting wire is pulled out, and when it is close, it is automatically retracted through the reset wheel, ensuring that the connecting wire is always in a tensioned state, avoiding cable entanglement, and ensuring the use effect.

After cooperation, the direction of the camera will be deflected, and the observer can intuitively understand that this is the locking state), and then the drive motor 8 is controlled to rotate forward / reverse as needed until the camera assembly 12 is adjusted to the appropriate direction.

[0049] When the equipment needs to be repaired, it is only necessary to control the electric telescopic rod 20 to be retracted, the first movable rod 24 to be retracted, and the transmission gear 6 wheel will move up under the action of the compression spring 27, so that the first and second bevel gears 23 are meshed, and the transmission gear 6 wheel is meshed with the transmission gear 6 circle 5. At the same time, the locking block 30 will be retracted into the locking cavity 28 under the action of the tension spring 31, and then the drive motor 8 is controlled to be turned on (forward rotation), and the drive motor 8 will drive the transmission gear 6 circle 5 to rotate through the drive gear 9 (in 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), thereby driving the transmission gear 6 wheel to rotate, and through the transmission of the first and second bevel gears 23, the climbing wheel 11 is driven to rotate in the opposite direction, thereby driving the ring sleeve 1 to move downward along the installation rod 2 as a whole. When it moves to a suitable position (a convenient position for maintenance), the drive motor 8 can be turned off. After the maintenance is completed, the installation operation can be repeated.

[0050] From the above description, it can be known that the climbing wheel 11 of the present application scheme cooperates with the transmission gear 6 wheel, the transmission gear 6 circle 5, and the drive motor 8, so as to freely control the up and down movement of the equipment, and is convenient for disassembly, assembly and maintenance. In addition, the scheme can adjust the position of the camera assembly 12 at a large angle through the setting of the connecting rod 14 connected to the transmission gear 6 circle 5 and the camera assembly 12 at the end of the connecting rod 14. With the rotation of the camera assembly 12 itself, it can monitor all circumferential angles of the mounting rod 2, which greatly improves the utilization rate of the device. When encountering foreign objects blocking it, the position of the camera assembly 12 can also be adjusted to avoid foreign objects for monitoring. It is highly practical and suitable for promotion and use.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
