Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, and in particular to a visual monitoring device for a wharf yard. Background Technology

[0002] With the booming development of global trade, terminal yards, as the core hubs for cargo distribution, have seen their scale and cargo throughput continuously increase. The efficient storage and circulation of various types of cargo, such as containers and bulk cargo, have placed higher demands on the visual monitoring of the yards. Traditional monitoring methods have gradually revealed problems such as fixed perspectives and limited coverage when facing complex and ever-changing terminal environments, making it difficult to meet the needs of real-time dynamic supervision, multi-target tracking, and rapid emergency response.

[0003] Existing terminal yard monitoring equipment mostly adopts fixed mechanical structures, which mainly fix the monitoring cameras to rigid support components such as concrete columns and steel structure brackets by welding or bolting. These support components are fixed in height, and the cameras can only face specific areas at a preset fixed angle. In terms of technical principle, traditional equipment relies on cameras with fixed viewing angles to collect video and transmit the images to the monitoring center through analog signals or network signals. Its monitoring range is completely determined by the installation location.

[0004] However, traditional fixed-view monitoring equipment has a core drawback: it cannot achieve wide-area rapid coverage and dynamic viewing angle adjustment in the yard. In the terminal yard, the container stacking layout changes frequently, loading and unloading machinery moves continuously, and transport vehicles shuttle back and forth. Fixed cameras can only cover a single area, making it difficult to continuously monitor cross-area operations. When it is necessary to check for abnormalities in the corners of the yard or track moving goods, staff need to manually switch between multiple fixed camera feeds, which is not only time-consuming and labor-intensive, but also easily creates blind spots in monitoring. This seriously restricts the safety management efficiency and emergency response capabilities of the terminal yard. Therefore, a visual monitoring device for the terminal yard is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a visual monitoring device for wharf yards, which aims to improve the problems of insufficient viewing angle adjustment capability, limited wide-area coverage, and poor adaptability to dynamic scenes caused by the fixed mechanical structure of existing wharf yard monitoring equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A visual monitoring device for a wharf yard includes a monitoring head and a support frame, wherein a rotating component is provided at the bottom of the monitoring head;

[0008] The rotating assembly includes a protective shell, the bottom of which is fixedly connected to the upper surface of the support frame. A support plate is fixedly connected inside the protective shell, and a motor is fixedly connected inside the support plate. A gear one is fixedly connected to the output end of the motor. A connecting rod is fixedly connected to the top of the support plate. A gear two is rotatably connected to the outer wall of the connecting rod. The gear two meshes with the gear one. A connecting frame is fixedly connected inside the gear two. The top of the connecting frame is fixedly connected to the bottom of the monitoring head. An adjustment assembly is provided on the top of the support frame.

[0009] As a further description of the above technical solution:

[0010] The adjustment assembly includes a collar and a sliding rod. The bottom of the collar is fixedly connected to the top of the support frame, and the sliding rod is slidably connected inside the support frame.

[0011] As a further description of the above technical solution:

[0012] The sliding rod is slidably connected to the collar, and the sliding rod has multiple slots inside.

[0013] As a further description of the above technical solution:

[0014] The collar is fixedly connected to symmetrical connecting shafts, and each connecting shaft is fixedly connected to a limiting plate.

[0015] As a further description of the above technical solution:

[0016] The limiting plate is internally connected to a sliding shaft, and a pull ring is fixedly connected to one end of the sliding shaft.

[0017] As a further description of the above technical solution:

[0018] The other end of the sliding shaft is fixedly connected to a locking post, which engages with the locking groove.

[0019] As a further description of the above technical solution:

[0020] An extrusion disc is fixedly connected to the outer wall of the sliding shaft, and the extrusion disc is slidably connected to the inner wall of the connecting shaft.

[0021] As a further description of the above technical solution:

[0022] A spring is provided on the outer wall of the sliding shaft. One end of the spring is fixedly connected to the side wall of the extrusion disc, and the other end is fixedly connected to the side wall of the limiting disc.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the motor output drives gear one to rotate, and the rotation of gear one further drives gear two to move synchronously, thereby making the connecting frame and the monitoring head rotate synchronously, realizing the effect of the monitoring head being able to rotate freely. This solves the problems of limited coverage and insufficient multi-target tracking capability of traditional fixed-view monitoring equipment, and improves the efficiency of dynamic monitoring of the entire yard area.

[0025] 2. In this utility model, by pulling the pull ring, the sliding shaft slides inside the connecting shaft, thereby further driving the locking column to disengage from the slot to unlock. After unlocking, the sliding rod can be pulled directly to slide inside the support frame, thereby achieving the effect of quickly adjusting the height of the monitoring head. This solves the problem of blind spots caused by obstruction or limited viewing angle of traditional fixed-height monitoring equipment, and improves the efficiency and flexibility of fine monitoring across the entire height range in complex yard environments.

[0032] 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.

[0033] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a visual monitoring device for a wharf yard, comprising a monitoring head 1 and a support frame 2. A rotating component is provided at the bottom of the monitoring head 1, which is used to rotate the angle of the monitoring head 1.

[0034] The rotating assembly includes a protective shell 3, the bottom of which is fixedly connected to the upper surface of the support frame 2. The protective shell 3 serves to protect the rotating assembly. A support plate 4 is fixedly connected inside the protective shell 3, and a motor 5 is fixedly connected inside the support plate 4. The motor 5 provides power to the rotating assembly and ensures stable movement of the rotating assembly. A gear 6 is fixedly connected to the output end of the motor 5. A connecting rod 7 is fixedly connected to the top of the support plate 4. A gear 8 is rotatably connected to the outer wall of the connecting rod 7. Gear 8 meshes with gear 6. Through the transmission action of gear 8 and gear 6, the monitoring head 1 can be rotated horizontally, ensuring that the monitoring angle can be dynamically adjusted. A connecting frame 9 is fixedly connected inside gear 8. The top of the connecting frame 9 is fixedly connected to the bottom of the monitoring head 1. An adjustment assembly is provided on the top of the support frame 2. The adjustment assembly is used to adjust the height of the monitoring head 1.

[0035] Specifically, when it is necessary to perform blind-spot scanning of a large area, dynamically track moving targets, or flexibly switch monitoring directions to deal with temporary emergencies, firstly, after the operator installs the device in a fixed position, the monitoring head 1 can perform effective monitoring. The rotation function of the monitoring head 1 is driven by the motor 5, and its output end is connected to gear 6. The drive of the motor 5 causes gear 6 to rotate. At the same time, the rotation of gear 6 drives the rotation of gear 8, which meshes with it. The rotation of gear 8 then drives the movement of the connecting frame 9 and the monitoring head 1. This linkage process allows the monitoring head 1 to flexibly adjust its monitoring coverage area, thereby reducing blind spots and ensuring a comprehensive monitoring effect.

[0036] Reference Figure 3 and Figure 4The adjustment assembly includes a collar 10 and a sliding rod 11. The bottom of the collar 10 is fixedly connected to the top of the support frame 2, and the sliding rod 11 is slidably connected inside the support frame 2. The collar 10 and the sliding rod 11 provide stable support and connection for the adjustment assembly. The sliding of the sliding rod 11 provides convenient adjustment for the operator. The sliding rod 11 is slidably connected to the collar 10. The sliding rod 11 has multiple slots 12 inside. The slots 12 are used to cooperate with other components to achieve quick locking and unlocking of the assembly. The collar 10 has symmetrical connecting shafts 13 fixedly connected inside. Each connecting shaft 13 has a limit plate 14 fixedly connected inside. The limit plate 14 has a sliding shaft 15 slidably connected inside. 5. A pull ring 16 is fixedly connected to one end of the sliding shaft 15. The pull ring 16 is made of rubber, which makes it convenient for the user to drive the movement of the adjustment component. A locking post 18 is fixedly connected to the other end of the sliding shaft 15. The locking post 18 fits into the locking groove 12. Through the cooperation of the locking post 18 and the locking groove 12, the stable adjustment of the adjustment component can be guaranteed. A pressing plate 17 is fixedly connected to the outer wall of the sliding shaft 15. The function of the pressing plate 17 is to transmit power, thereby driving the spring 19 to undergo elastic deformation. The pressing plate 17 is slidably connected to the inner wall of the connecting shaft 13. A spring 19 is provided on the outer wall of the sliding shaft 15. The function of the spring 19 is to provide elastic restoring force for the locking post 18. One end of the spring 19 is fixedly connected to the side wall of the pressing plate 17, and the other end is fixedly connected to the side wall of the limiting plate 14.

[0037] Specifically, when there are obstructions of varying heights in the monitored area, or when it is necessary to flexibly switch between wide-area panoramic monitoring and close-up detail monitoring, the operator applies a pulling force by pulling the pull ring 16. The pulling force causes the sliding shaft 15 to slide inside the limiting plate 14. The sliding of the sliding shaft 15 triggers the synchronous movement of the squeezing plate 17 and the locking column 18, releasing the engagement between the locking column 18 and the slot 12, thus unlocking the device. After unlocking, the operator can directly pull the sliding rod 11 to slide it inside the support frame 2, thereby adjusting the height of the monitoring head 1. During this process, the movement of the squeezing plate 17 causes it to compress the spring 19. The spring 19 undergoes elastic deformation, storing elastic potential energy. This ensures that after the monitoring head 1 is adjusted to the appropriate position, the restoring force of the spring 19 will push the locking column 18 back into the slot 12, completing the automatic locking. This achieves flexible adjustment of the monitoring device, allowing users to make adjustments according to the usage situation.

[0038] Working Principle: When using this dockyard monitoring device, the operator first installs the device in a fixed position. Monitoring head 1 enables monitoring. When the monitoring head 1 needs to rotate freely, the output of motor 5 drives gear 6 to rotate. Simultaneously, gear 6 drives gear 8, which meshes with it, to rotate synchronously on the outer wall of connecting rod 7. This causes the connecting frame 9 and monitoring head 1 to move, allowing the monitoring head 1 to freely adjust its monitoring coverage area and minimize blind spots. When the height of the monitoring head 1 needs to be adjusted, the operator pulls the pull ring 16. Under the pulling force, the sliding shaft 15 will move within the limiting plate 14. The sliding shaft 15 further drives the pressing plate 17 and the locking column 18 to move synchronously. When the locking column 18 slides, it will disengage from the locking groove 12 to unlock. After unlocking, the operator can directly pull the sliding rod 11 to make the sliding rod 11 slide inside the support frame 2, which will further drive the monitoring head 1 to adjust its height. During the movement of the pressing plate 17, the spring 19 will be squeezed, causing the spring 19 to undergo elastic deformation and store elastic potential energy. After the monitoring head 1 is adjusted to the appropriate position, the elastic restoring force of the spring 19 will push the locking column 18 to re-lock into the locking groove 12 to ensure the stability of the device after adjustment.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
