Description

Technical Field

[0001] This utility model relates to the field of slope monitoring technology, and in particular to a rockfall monitoring device for high slopes. Background Technology

[0002] Rockfalls from high slopes are one of the most common geological hazards in mountainous areas. They are widely distributed and occur frequently, especially in the western mountainous areas along main transportation routes, in mountain towns, along power transmission lines, and at hydropower station sites, seriously threatening the lives and property of the general public.

[0003] A rockfall monitoring device is available, comprising components such as a pole, a power distribution box, a phased array radar host, a camera, and an alarm. The camera monitors slope conditions in real time. However, the camera's operation in the complex environment of high slopes is frequently affected by factors such as temperature, animals, falling rocks, and humidity. This necessitates regular maintenance, but the camera is mounted on a high pole, requiring staff to climb the pole for inspection, which is inconvenient, time-consuming, and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a high slope rockfall monitoring device to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of the present invention provides a high slope rockfall monitoring device, including a support assembly and a camera. The support assembly is provided with a protective cover, and the camera is disposed inside the protective cover. The support assembly is provided with a mounting box, and the mounting box is provided with a lifting assembly that can drive the camera to move up and down. The camera is provided with a traction assembly to prevent the camera from rotating during the lifting and lowering process.

[0007] The above technical solution works as follows: When camera maintenance is required, a lifting assembly controls the camera's downward movement. During this process, a traction assembly restrains the camera to prevent rotation. Workers then perform maintenance on the camera at the appropriate height. After maintenance, the lifting assembly moves the camera back to its original position for monitoring. Under the constraint of the traction assembly, the camera's monitoring angle remains constant, ensuring effective monitoring.

[0008] Preferably, in any of the above embodiments, the lifting assembly includes a take-up shaft rotatably connected in the mounting box, a lifting rope with one end fixed to the take-up shaft and the other end connected to the camera, and a motor capable of driving the take-up shaft to rotate forward and backward.

[0009] The above technical solution utilizes a motor to drive the lifting rope to wind or unwind on the take-up shaft, thereby adjusting the height of the camera and making it convenient to lower the camera for maintenance when needed.

[0010] Preferably, in any of the above embodiments, the pulling assembly includes two pulling ropes with their ends connected to the take-up shaft and the camera, respectively, and the two pulling ropes are symmetrically arranged on both sides of the lifting rope.

[0011] The above technical solution involves two pull ropes that constrain the camera from both sides, and the pull ropes and lifting ropes are wound or released synchronously, allowing the camera to move vertically in a fixed direction, thus preventing the camera from rotating during the lifting process.

[0012] Preferably, in any of the above embodiments, the pulling assembly further includes a guide shaft rotatably connected within the mounting box, both ends of the guide shaft being lead screws, and both ends of the guide shaft being threadedly connected to guide blocks, the guide blocks being sleeved on the outside of the pulling rope, and a transmission assembly being provided between the take-up shaft and the guide shaft to enable the two to rotate synchronously.

[0013] The above technical solution works as follows: when the take-up shaft rotates, the transmission component drives the guide shaft to rotate, and the guide shaft drives the guide block on it to move horizontally. Under the constraint of the guide block, the traction rope is wound orderly on the take-up shaft, which avoids the traction rope from stacking disorderly on the take-up shaft, making the camera more stable during lifting and lowering.

[0014] Preferably, in any of the above embodiments, a constraint shaft is also fixedly connected inside the mounting box, and the guide block is sleeved on the outside of the constraint shaft.

[0015] By adopting the above technical solution, the constraint axis can constrain the guide block and prevent the guide block from displacing in other directions.

[0016] Preferably, in any of the above schemes, the lead screws used at both ends of the guide shaft are reciprocating lead screws.

[0017] Using the above technical solution: Under the action of the reciprocating screw, after the guide block moves to one end, it rotates in the opposite direction and continues to move, so that the pulling rope can be stacked and wound up without adjusting the rotation direction of the guide shaft.

[0018] Preferably, in any of the above embodiments, two partitions are fixedly connected to the winding shaft, and the lifting rope is disposed between the two partitions.

[0019] The above technical solution uses a partition to separate the lifting rope from the pulling rope, preventing them from stacking together during the winding process and affecting their use.

[0020] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. This high slope rockfall monitoring device, through its installation box, lifting assembly, and traction assembly, allows for easy camera maintenance. When maintenance is required, the lifting assembly lowers the camera, while the traction assembly restrains it to prevent rotation. Workers then inspect the camera at the appropriate height. After maintenance, the lifting assembly returns the camera to its original position for continued monitoring. The traction assembly maintains the camera's monitoring angle, ensuring effective monitoring. No climbing is required, making maintenance safer and more convenient.

[0021] 2. This high slope rockfall monitoring device, through the setting of a guide shaft, guide blocks, and transmission components, etc., when the winding shaft rotates, the transmission components drive the guide shaft to rotate, and the guide shaft drives the guide blocks on it to move horizontally. Under the constraint of the guide blocks, the traction rope is wound orderly on the winding shaft, which can avoid the traction rope from stacking disorderly on the winding shaft, and the camera is more stable during the lifting and lowering process.

[0022] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] like Figures 1-4 As shown, this utility model includes a support component 1 and a camera 5. A protective cover 2 is provided on the support component 1, and the camera 5 is disposed inside the protective cover 2. A mounting box 3 is provided on the support component 1, and a lifting component 4 that can drive the camera 5 to move up and down is provided inside the mounting box 3. A pulling component 6 is provided on the camera 5 to prevent the camera 5 from rotating during the lifting process.

[0028] When maintenance is required on camera 5, the lifting assembly 4 controls its downward movement. During this process, the traction assembly 6 restrains camera 5 to prevent it from rotating. Workers then inspect camera 5 at the appropriate height. After inspection, the lifting assembly 4 moves camera 5 back to its original position for monitoring. Under the restraint of the traction assembly 6, the monitoring angle of camera 5 remains unchanged, ensuring effective monitoring.

[0029] It should be noted that the entire rockfall monitoring device should also include necessary components such as a power distribution box, radar, and alarm. Since these components do not involve the core innovation of this application, there are no additional requirements for them. Commonly used technologies in the prior art can be used for these components, and they will not be described in detail.

[0030] Example 1: The lifting assembly 4 includes a take-up shaft 401 rotatably connected within the mounting box 3, a lifting rope 402 with one end fixed to the take-up shaft 401 and the other end connected to the camera 5, and a motor 403 capable of driving the take-up shaft 401 to rotate forward and backward. The pulling assembly 6 includes two pulling ropes 601 with their ends respectively connected to the take-up shaft 401 and the camera 5, and the two pulling ropes 601 are symmetrically arranged on both sides of the lifting rope 402.

[0031] Specifically: The motor 403 drives the lifting rope 402 to wind or unwind on the take-up shaft 401, thus adjusting the height of the camera 5 for easy lowering for maintenance when needed. Two pull ropes 601 constrain the camera 5 from both sides, and the pull ropes 601 and the lifting rope 402 wind or unwind synchronously, allowing the camera 5 to move vertically in a fixed direction, thus preventing the camera 5 from rotating during lifting.

[0032] Example 2: The traction assembly 6 also includes a guide shaft 602 rotatably connected within the mounting box 3. Both ends of the guide shaft 602 are lead screws, and both ends of the guide shaft 602 are threadedly connected to guide blocks 603. The guide blocks 603 are sleeved on the outside of the traction rope 601. A transmission assembly 604 is provided between the winding shaft 401 and the guide shaft 601 to enable them to rotate synchronously. A constraint shaft 605 is also fixedly connected within the mounting box 3, and the guide blocks 603 are sleeved on the outside of the constraint shaft 605.

[0033] Specifically: When the take-up shaft 401 rotates, the transmission assembly 604 drives the guide shaft 602 to rotate, and the guide shaft 602 drives the guide block 603 on it to move horizontally. Under the constraint of the guide block 603, the traction rope 601 is wound orderly on the take-up shaft 401, which avoids the traction rope 601 from stacking disorderly on the take-up shaft 401, making the camera 5 more stable during lifting and lowering. The constraint shaft 605 can constrain the guide block 603 to prevent the guide block 603 from moving in other directions.

[0034] Example 3: The lead screws used at both ends of the guide shaft 602 are reciprocating lead screws. Two partitions are fixedly connected to the take-up shaft 401, and the lifting rope 402 is disposed between the two partitions.

[0035] Specifically: Under the action of the reciprocating screw, the guide block 603 moves to one end and then rotates in the opposite direction to continue moving, allowing the pull rope 601 to be layered and wound up without needing to adjust the rotation direction of the guide shaft 602. The partition separates the lifting rope 402 from the pull rope 601, preventing them from stacking together during the winding process and affecting their use.

[0036] The working principle of this utility model is as follows: S1, Camera 5 monitors the rockfall situation on the slope on the support component 1; S2. When it is necessary to inspect the camera 5, the lifting component 4 is used to control the camera 5 to move down. During this process, the pulling component 6 restrains the camera 5 to prevent it from rotating during the downward movement. S3. Staff inspect the camera 5, which has been lowered to a suitable height. After the inspection, the lifting assembly 4 moves the camera 5 back to its original position for monitoring. Under the constraint of the pulling assembly 6, the monitoring angle of the camera 5 remains unchanged, ensuring the monitoring effect.

[0037] Compared with the prior art, the present invention has the following advantages: 1. This high slope rockfall monitoring device, through the installation box 3, lifting assembly 4, and traction assembly 6, etc., allows for easy access when maintenance is required for camera 5. The lifting assembly 4 lowers camera 5, while the traction assembly 6 restrains it to prevent rotation during descent. Workers then inspect camera 5 at the appropriate height. After inspection, the lifting assembly 4 moves camera 5 back to its original position for monitoring. Under the restraint of the traction assembly 6, the monitoring angle of camera 5 remains constant, ensuring effective monitoring. No climbing is required for high-altitude operations, making maintenance safer and more convenient.

[0038] 2. This high slope rockfall monitoring device, through the configuration of a guide shaft 602, guide block 603, and transmission component 604, etc., when the winding shaft 401 rotates, the transmission component 604 drives the guide shaft 602 to rotate, and the guide shaft 602 drives the guide block 603 on it to move horizontally. Under the constraint of the guide block 603, the traction rope 601 is orderly wound onto the winding shaft 401, thus avoiding disorderly stacking of the traction rope 601 on the winding shaft 401, and making the camera 5 more stable during the lifting and lowering process.
