Description

Technical Field

[0001] This utility model belongs to the field of railway monitoring equipment, specifically relating to a dedicated railway video monitoring device. Background Technology

[0002] The railway is an organic whole composed of multiple specialties and departments, each with its own division of labor and overlapping operations and workspaces. In particular, the video surveillance system of dedicated railway lines is a comprehensive system capable of meeting the needs of multiple services, job types, departments, locations, and purposes. To achieve multi-space and multi-service collaboration of the video surveillance system, monitoring equipment needs to be installed in various areas such as railway stations, barriers, and waiting areas. Most existing railway video surveillance devices have poor image stabilization capabilities, resulting in poor video surveillance performance in harsh environments such as barriers and track areas with strong winds, high vibrations, and high noise levels on dedicated railway lines. Furthermore, existing monitoring devices are not convenient for adjusting the installation angle of the surveillance cameras, thus significantly limiting the monitoring field of view. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model aims to provide a dedicated railway video monitoring device. This device can significantly improve the anti-shake capability of the monitoring equipment, and the monitoring device is easy to install and the monitoring angle is very convenient to adjust.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A dedicated railway video surveillance device includes a mounting base and a monitoring camera. The mounting base includes a base plate and two horizontal plates. The base plate is vertically fixed to a wall. The ends of the two horizontal plates are horizontally spaced on the base plate. A shock-absorbing plate is horizontally movable between the two horizontal plates. The top and bottom of the shock-absorbing plate are connected to the two horizontal plates by corresponding shock-absorbing spring assemblies. A clamping plate and a rotating plate are horizontally movable at the ends of the shock-absorbing plate. The clamping plate is located above the rotating plate, and the rotating plate is clamped and fixed between the clamping plate and the shock-absorbing plate by clamping components. A housing is vertically fixed at the end of the rotating plate. An angle adjustment assembly is provided inside the housing, and the monitoring camera is mounted on the moving part of the angle adjustment assembly.

[0005] Preferably, the shock-absorbing spring assembly includes a slide rod and two springs. The slide rod is vertically fixed between two horizontal plates. A first vertical hole is vertically opened through the shock-absorbing plate. The slide rod is vertically slidably sleeved in the first vertical hole. The two springs are sleeved on the slide rod above and below the shock-absorbing plate, and the two ends of the springs abut against the shock-absorbing plate and the horizontal plate, respectively.

[0006] Preferably, the upper horizontal plate is fixed on the base plate, and the lower horizontal plate is vertically slidably mounted on the base plate. Both horizontal plates are vertically perforated with corresponding second vertical holes. The upper and lower ends of the slide rod move through the corresponding second vertical holes and extend outward. The two ends of the slide rod are provided with threaded heads, and the threaded heads are threaded with first nuts. The two first nuts are respectively pressed onto the upper and lower horizontal plates.

[0007] Preferably, the end of the anti-seismic plate is provided with a notch, and the end of the clamping plate is vertically slidably installed on the inner sidewall of the notch; the clamping member includes a threaded post vertically fixed on the bottom surface of the notch, and the middle parts of the clamping plate and the anti-seismic plate are vertically movably sleeved on the threaded post, and a second nut threaded above the threaded post is pressed onto the upper part of the clamping plate.

[0008] Preferably, the inner bottom surface of the notch and the lower surface of the clamping plate are both fixed with annular first engagement teeth centered on the threaded post, and the upper and lower surfaces of the rotating plate are provided with second engagement teeth, and the first engagement teeth and the second engagement teeth mesh with each other.

[0009] Preferably, the angle adjustment assembly includes a fan ring plate, a connecting rod, and a screw. Multiple guide wheels are tangentially arranged on the outer and inner circumferential surfaces of the fan ring plate, and the guide wheels are installed inside the housing. The connecting rod is fixedly disposed in the middle of the fan ring plate along its radial direction. One end of the connecting rod is rotatably connected to a moving block, which is threaded onto the screw. The screw is obliquely installed inside the housing, and an adjustment part is installed at its outwardly extending end. An arc-shaped opening is formed on the housing along the rotational swing direction of the fan ring plate, and a first mounting block is fixedly disposed on the connecting rod corresponding to the arc-shaped opening. A movable opening is formed on the housing, and a second mounting block is fixedly disposed on the end of the connecting rod away from the moving block at the movable opening. The monitoring camera is installed between the two mounting blocks.

[0010] Preferably, the fan ring plate has a concentric arc-shaped groove, and the locking bolt installed in the box is inserted into the arc-shaped groove and pressed against the fan ring plate.

[0011] Preferably, the arc-shaped groove is formed at a position opposite to the arc-shaped opening.

[0012] Preferably, the adjustment part includes a crank handle, which is mounted on the outer end of the screw extending out of the housing.

[0013] Preferably, the adjusting part includes a bolt head extending out of the housing body.

[0014] The beneficial effects of this utility model are as follows: 1. In this application, by turning the first nuts at both ends of the slide rod, the clamping force of the springs at the upper and lower ends of the anti-vibration plate can be adjusted. The elastic force of the upper and lower sets of springs can effectively absorb the vibration of the anti-vibration plate, thereby effectively reducing the vibration force transmitted to the monitoring camera and improving the quality of video monitoring.

[0015] 2. The enclosure of this application is mounted on the anti-vibration plate via a rotating plate. The rotating plate and the clamping plate are fitted onto the threaded post. By rotating the horizontal angle of the rotating plate, the horizontal direction of the enclosure and the monitoring camera can be effectively adjusted. By rotating and turning the second nut, the clamping plate is pressed downward against the rotating plate. The second engagement teeth on the upper and lower surfaces of the rotating plate will engage with the corresponding first engagement teeth, thereby achieving horizontal locking and fixing of the rotating plate. This clamps the rotating plate between the clamping plate and the recess, significantly improving the fixing firmness of the rotating plate.

[0016] 3. When the crank handle drives the screw to rotate, under the limiting action of the fan ring plate and the guide wheel, the moving block can drive the connecting rod to rotate and swing, so that the first mounting block can swing and move in the arc-shaped opening, thereby effectively adjusting the monitoring angle of the surveillance camera.

[0017] 4. After adjusting the monitoring angle of the surveillance camera, this application uses a wrench or other tools to penetrate the arc-shaped opening and tighten the locking bolts in the housing. This tightening bolts then press and fix the fan ring plate, further locking the angle adjustment component and significantly improving the installation stability of the surveillance camera.

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of application of this utility model.

[0020] like Figure 1-3As shown, this utility model proposes a dedicated railway video monitoring device, including a mounting base and a monitoring camera 5. The mounting base includes a base plate 1 and two horizontal plates 2. The base plate 1 is vertically fixed to the wall by fixing bolts. The ends of the two horizontal plates 2 are horizontally spaced on the base plate 1. A shock-absorbing plate 3 is horizontally movable between the two horizontal plates 2. The top and bottom of the shock-absorbing plate 3 are connected to the two horizontal plates 2 by corresponding shock-absorbing spring assemblies. The shock-absorbing spring assembly includes a sliding rod 21 and two springs 22. A first vertical hole is vertically opened through the shock-absorbing plate 3. The middle part of the sliding rod 21 is vertically slidably sleeved in the first vertical hole. The two springs 22 are sleeved on the sliding rod 21 above and below the shock-absorbing plate 3, and the two ends of the springs 22 abut against the shock-absorbing plate 3 and the horizontal plates 2, respectively. In this embodiment, the upper horizontal plate 2 is fixed on the base plate 1, and the lower horizontal plate 2 is vertically slidably mounted on the base plate 1. Both horizontal plates 2 have corresponding second vertical holes that are vertically opened through them. The upper and lower ends of the slide rod 21 are movably inserted through the corresponding second vertical holes and extend outward. The two ends of the slide rod 21 are provided with threaded heads 211, and the threaded heads 211 are threaded with first nuts 23. The two first nuts 23 are respectively pressed onto the upper and lower horizontal plates 2.

[0021] In this application, by turning the first nuts 23 at both ends of the slide bar 21, the clamping force of the springs 22 at the upper and lower ends of the anti-vibration plate 3 can be adjusted. The elastic force of the upper and lower sets of springs 22 can effectively absorb the vibration of the anti-vibration plate 3, thereby effectively reducing the vibration force transmitted to the monitoring camera 5 and improving the video monitoring quality.

[0022] The end of the seismic plate 3 is horizontally movably equipped with a clamping plate 61 and a rotating plate 6. The clamping plate 61 is located above the rotating plate 6, and the rotating plate 6 is clamped and fixed between the clamping plate 61 and the seismic plate 3 by a clamping member. The end of the rotating plate 6 is vertically fixed with a box 4. Specifically, the end of the seismic plate 3 is provided with a notch 31, and the end of the clamping plate 61 is vertically slidably installed on the inner wall of the notch 31. The clamping member includes a threaded post 7 vertically fixed on the inner bottom surface of the notch 31. The middle parts of the clamping plate 61 and the seismic plate are vertically movably sleeved on the threaded post 7. The second nut 71 threadedly connected above the threaded post 7 is pressed against the upper part of the clamping plate 61. Furthermore, the inner bottom surface of the notch 31 and the lower surface of the clamping plate 61 are both fixed with annular first engagement teeth 82 centered on the threaded post 7. The upper and lower surfaces of the rotating plate 6 are provided with second engagement teeth 81, and the first engagement teeth 82 and the second engagement teeth 81 mesh with each other.

[0023] The housing 4 of this application is mounted on the anti-vibration plate 3 via a rotating plate 6. The rotating plate 6 and the clamping plate 61 are fitted onto the threaded post 7. By rotating the horizontal angle of the rotating plate 6, the horizontal direction of the housing 4 and the monitoring camera 5 can be effectively adjusted. By rotating and turning the second nut 71, the clamping plate 61 is pressed downward against the rotating plate 6. The second engagement teeth 81 on the upper and lower surfaces of the rotating plate 6 will engage with the corresponding first engagement teeth 82, thereby achieving horizontal locking and fixing of the rotating plate 6. This clamps the rotating plate 6 between the clamping plate 61 and the recess 31, which can significantly improve the fixing firmness of the rotating plate 6.

[0024] An angle adjustment assembly is provided inside the housing 4, and a monitoring camera 5 is mounted on the actuating part of the angle adjustment assembly. Specifically, the angle adjustment assembly includes a fan ring plate 46, a connecting rod 44, and a screw 42. Multiple guide wheels 45 are tangentially arranged on the outer and inner circumferential surfaces of the fan ring plate 46, and the guide wheels 45 are installed inside the housing 4. Under the guiding and limiting action of the guide wheels 45, the fan ring plate 46 can rotate and swing along its circumferential surface. The connecting rod 44 is fixedly located in the middle of the fan ring plate 46 in the radial direction. One end of the connecting rod 44 is rotatably connected to a moving block 43, which is threaded onto the screw 42. The screw 42 is obliquely installed inside the housing 4, and an adjustment part is installed at its outwardly extending end. The adjustment part can be a crank handle 41 or a bolt head structure. The bolt head can be a hexagonal bolt head, which is used in conjunction with an Allen wrench. In this embodiment, the adjustment part includes a crank handle 41, which is mounted on the outer end of the screw 42 extending out of the housing 4. The crank handle 41 of this application is located outside the housing 4, which facilitates the adjustment and rotation of the screw 42. The crank handle 41 drives the screw 42 to rotate, causing the moving block 43 to move along the length of the screw 42. This, in turn, under the limiting action of the fan ring plate 46 and the guide wheel 45, drives the connecting rod 44 to rotate and swing. Specifically, the housing 4 has an arc-shaped opening 40 along the rotational swing direction of the fan ring plate 46, and a first mounting block 441 is fixed to the connecting rod 44 corresponding to the arc-shaped opening 40. The housing 4 also has a movable opening, and the end of the connecting rod 44 away from the moving block 43 extends outward from the movable opening and is fixed to a second mounting block 442. The monitoring camera 5 is mounted between the two mounting blocks along the length of the connecting rod 44.

[0025] When the crank 41 drives the screw 42 to rotate, under the limiting action of the fan ring plate 46 and the guide wheel 45, the moving block 43 can drive the connecting rod 44 to rotate and swing, so that the first mounting block 441 can swing and move in the arc-shaped opening 40, thereby effectively adjusting the monitoring angle of the surveillance camera 5.

[0026] Furthermore, an arc-shaped groove 461 is concentrically formed on the fan ring plate 46. A locking bolt 47 installed inside the housing 4 passes through the arc-shaped groove 461 and presses against the fan ring plate 46. The arc-shaped groove 461 is located at the opposite position of the arc-shaped opening 40. After adjusting the monitoring angle of the surveillance camera 5, a wrench or other tool is used to penetrate the arc-shaped opening 40 and insert into the housing 4 to tighten the locking bolt 47. This causes the locking bolt 47 to press against and fix the fan ring plate 46, further locking the angle adjustment component and significantly improving the installation stability of the surveillance camera 5.

[0027] When using this utility model, the mounting base is fixed to the wall of the monitoring area by using the fixing bolts through the base plate 1; after adjusting the horizontal angle of the monitoring by rotating the rotating plate 6, the second nut 71 is tightened to lock the rotating plate 6; then the crank handle 41 is rotated, and the angle on the vertical plane of the monitoring camera 5 is adjusted by the cooperation of the screw 42, the moving block 43, the connecting rod 44, the fan ring plate 46, etc. After the adjustment is completed, the locking bolt 47 is tightened and locked by inserting a tool into the arc-shaped opening 40, and the installation operation of the monitoring camera 5 is completed.
