Description

Technical Field

[0001] This utility model relates to the field of monitoring technology, and in particular to a monitoring device and a monitoring system. Background Technology

However, lowering the height of the dome camera makes it easier for people to reach it, making it vulnerable to damage. This can lead to property damage or even personal injury at the location of the surveillance system. Utility Model Content

Detailed Implementation

[0025] 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.

[0026] The purpose of this utility model is to provide a monitoring device and monitoring system that can expand the monitoring range without lowering the height of the monitoring device, reduce the blind spot at the corner of the wall where the monitoring device is located, avoid property damage and personal injury caused by the monitoring device being damaged due to its low position, and solve the problems existing in the prior art.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figures 1-5 The present invention will be further described in detail below with reference to specific embodiments.

[0028] Example 1

[0029] This embodiment provides a monitoring device 100, for reference... Figures 1-2 The system includes a monitoring unit 1 for acquiring image information and an adjustment mechanism. The adjustment mechanism is assembled and connected to the monitoring unit 1 so that the acquisition direction of the monitoring unit 1 can be adjusted to face the wall where the monitoring unit 1 is located by driving the monitoring unit 1 to rotate. By setting up the adjustment mechanism, the acquisition direction of the monitoring unit 1 can be adjusted without lowering the height of the monitoring device 100. This reduces the blind spot at the corner of the wall where the monitoring device 100 is located, and makes it difficult for people to touch the monitoring device 100. This reverses the disadvantage of surveillance cameras, changing the situation where a lower installation position reduces the blind spot to a higher installation position, thus avoiding property damage and personal injury caused by damage to the monitoring device 100.

[0030] In some implementations, reference Figures 1-2 The adjustment mechanism includes a first mounting structure and an angle adjustment mechanism 3. The monitoring unit 1 is mounted on the first mounting structure. The angle adjustment mechanism 3 is assembled and connected to the first mounting structure. The angle adjustment mechanism 3 can drive the first mounting structure to rotate around a first axis, so that the acquisition direction of the monitoring unit 1 can be adjusted to face the wall. By setting the angle adjustment mechanism 3 and driving the monitoring unit 1 mounted on the first mounting structure to rotate around the first axis, the acquisition direction of the monitoring unit 1 can be adjusted to face the wall, thereby further expanding the monitoring range of the monitoring unit 1, reducing blind spots, and avoiding the situation in the prior art where the installation position of the monitoring unit 1 needs to be lowered, resulting in the damage to the monitoring.

[0031] In some implementations, reference Figures 2-3 The angle adjustment mechanism 3 includes a fixed frame 31, a second mounting structure 32, and a first drive mechanism. The fixed frame 31 is used to fix it to the wall. The second mounting structure 32 is rotatably mounted on the fixed frame 31 via a rotating shaft 33, the axis of which is a first axis. The second mounting structure 32 is connected to the first mounting structure. The first drive mechanism is located on the fixed frame 31 and can drive the second mounting structure 32 to rotate around the first axis, so that the acquisition direction of the monitoring unit 1 can be adjusted to face the wall. By setting the second mounting structure 32, the first drive mechanism can drive the second mounting structure 32 to rotate around the axis of the rotating shaft 33, thereby driving the first mounting structure connected to the second mounting structure 32 to rotate around the rotating shaft 33, realizing the adjustment of the acquisition direction of the monitoring unit 1. The structure is simple and easy to implement.

[0032] In some implementations, reference Figures 2-3The fixing frame 31 is a U-shaped frame, which includes a first horizontal plate 311, a second horizontal plate 312, and a vertical plate 313. The vertical plate 313 is used to fix it to the wall. The first horizontal plate 311 and the second horizontal plate 312 are respectively set at the top and bottom of the vertical plate 313. The rotating shaft 33 is rotatably connected to the end of the second horizontal plate 312 away from the vertical plate 313, and the rotating shaft 33 is parallel to the vertical plate 313. The first driving mechanism includes a first motor 34, a lead screw 35, a sleeve 36, and a telescopic rod 37. The first motor 34 is set in the U-shaped frame. Inside the frame, near the bottom of the vertical plate 313, a lead screw 35 is arranged at an angle, with one end coaxially connected to the output shaft of the first motor 34, and the other end rotatably connected to the end of the first horizontal plate 311 away from the vertical plate 313. A sleeve 36 is fitted around the outer circumference of the lead screw 35 and threadedly connected to it. A telescopic rod 37 is connected between the second mounting structure 32 and the sleeve 36, with one end of the second mounting structure 32 fixedly connected to the telescopic rod 37, and the other end of the sleeve 36 rotatably connected to the telescopic rod 37. By setting the first motor 34 to drive the lead screw 35 to rotate, the sleeve 36 can be driven to slide from one end of the lead screw 35 to the other end, thereby driving the telescopic rod 37 to rotate around the rotation axis 33, and driving the second mounting structure 32 to rotate around the axis of the rotation axis 33, so that the acquisition direction of the monitoring unit 1 can be adjusted towards the wall. And when the sleeve 36 slides to both ends of the lead screw 35, the rotation angle of the monitoring unit 1 is limited. In this embodiment, the telescopic rod 37 includes an outer rod and an inner rod that slides inside the outer rod. The ends of the outer rod and the inner rod that are far apart from each other are respectively connected to the sleeve 36 and the second mounting structure 32. When the telescopic rod 37 is extended by rotating under the drive of the sleeve 36, the inner rod extends out of the outer rod. When the telescopic rod 37 is shortened by rotating under the drive of the sleeve 36, the inner rod retracts into the outer rod. In some other embodiments, a motor can also be provided, so that the gear fixed on the output shaft of the motor directly meshes with the gear ring sleeved on the outside of the rotating shaft 33 to drive the rotating shaft 33 to rotate. In some other embodiments, the rotating shaft 33 can also be rotatably connected to the end of the first horizontal plate 311 away from the vertical plate 313. The first motor 34 is set near the top of the vertical plate 313. One end of the lead screw 35 is fixedly connected to the output shaft of the first motor 34, and the other end of the lead screw 35 is rotatably connected to the end of the second horizontal plate 312 away from the vertical plate 313, thereby adjusting the overall layout of the monitoring device 100 according to the specific site conditions. In some other embodiments, the entire monitoring device 100 can be installed by flipping it upside down to adapt to different scenario requirements.

[0033] In some implementations, reference Figures 2-3The first mounting structure is a mounting cylinder 2. The first end of the mounting cylinder 2 is connected to the side of the second mounting structure 32 opposite to the telescopic rod 37. The second end of the mounting cylinder 2 is equipped with a monitoring unit 1. By setting up the mounting cylinder 2 and installing the monitoring unit 1 at the second end of the mounting cylinder 2, the first drive mechanism can drive the second mounting structure 32 to rotate, thereby driving the monitoring unit 1 inside the mounting cylinder 2 to rotate and adjust the acquisition angle towards the wall. The structure is simple and easy to implement.

[0034] In some implementations, reference Figures 2-4 The first end of the mounting cylinder 2 is movably engaged with the second mounting structure 32, and the second mounting structure 32 is connected to the first end of the mounting cylinder 2 via a rotation adjustment mechanism. The rotation adjustment mechanism can drive the mounting cylinder 2 to rotate in place relative to the second mounting structure 32 around its axis, thereby causing the monitoring unit 1 to rotate relative to the second mounting structure 32. By movably engaging the first end of the mounting cylinder 2 with the second mounting cylinder 2, and then driving the mounting cylinder 2 to rotate relative to the second mounting structure 32 via the rotation adjustment mechanism, the monitoring unit 1 mounted on the mounting cylinder 2 can rotate synchronously with the mounting cylinder 2. This, combined with the first drive mechanism, causes the monitoring unit 1 to change its acquisition direction, expanding the monitoring range of the monitoring unit 1 and reducing blind spots.

[0035] In some implementations, reference Figures 2-4The second end face of the mounting cylinder 2 is a beveled surface 22 arranged at an angle to the axis of the mounting cylinder 2, providing space for the tilted installation of the monitoring lens 11. The monitoring unit 1 includes a monitoring lens 11 and a zoom mechanism 12. The monitoring lens 11 is located at the second end of the mounting cylinder 2, and the mounting end of the monitoring lens 11 is embedded and fixed inside the second end of the mounting cylinder 2, so that the monitoring lens 11 is installed at an angle to the mounting cylinder 2. The end of the monitoring lens 11 opposite to the mounting end is the acquisition end, and the acquisition end is located outside the mounting cylinder 2. The zoom mechanism 12 is set at the acquisition end, which can realize the zoom adjustment of the monitoring lens 11. Furthermore, by setting the beveled surface 22 at an angle to the axis of the mounting cylinder 2, the monitoring unit 1 is tilted and installed in the mounting cylinder 2. As the mounting cylinder 2 rotates, it drives the monitoring unit 1 to rotate, thereby realizing the change of the acquisition direction. In conjunction with the first drive mechanism, the monitoring unit 1 can also be driven to adjust the acquisition direction of the monitoring unit 1 towards the wall, further expanding the monitoring range of the monitoring unit 1 and reducing the blind spot. Specifically, the angle between the oblique surface 22 and the axis of the mounting cylinder 2 ranges from 30° to 70°. In this embodiment, a fixing plate 21 is provided inside the mounting cylinder 2, and the rotation adjustment mechanism is a second motor 4. The body of the second motor 4 is fixed to the second mounting structure 32, and the output shaft of the second motor 4 is directly fixedly connected to the fixing plate 21, making the output shaft of the second motor 4 perpendicular to the fixing plate 21. The rotation of the output shaft of the second motor 4 can drive the mounting cylinder 2 to rotate relative to the second mounting structure 32. The structure is simple and easy to implement. Furthermore, the second motor 4 is located within the space surrounded by the second mounting structure 32, the mounting cylinder 2, and the fixing plate 21, which can reduce the environmental erosion of the second motor 4 and ensure the service life of the second motor 4. In some other embodiments, the second motor 4 can also be connected to the external transmission of the mounting cylinder 2 to drive the mounting cylinder 2 to rotate. By setting the zoom mechanism 12, the monitoring lens 11 can realize the zoom function, enabling the monitoring lens 11 to achieve long-distance shooting, increasing the coverage and applicability of the monitoring device 100.

[0036] In some implementations, reference Figure 4 The zoom mechanism 12 includes a lens 121 and a lens driving mechanism. The lens 121 is positioned in the acquisition direction. The lens driving mechanism is located at the second end of the mounting cylinder 2 and connected to the lens 121. The lens driving mechanism can drive the lens 121 to move closer to or further away from the acquisition end along the acquisition direction. By setting the lens 121 and the lens driving mechanism, the lens driving mechanism can drive the lens 121 to move closer to or further away from the acquisition end of the monitoring lens 11 to achieve changes in the shooting distance. The structure is simple and easy to implement.

[0037] In some implementations, reference Figures 4-5The lens driving mechanism includes a drive cylinder 123, a lens fixing cylinder 124, and a third motor 122. The drive cylinder 123 is a hollow cylinder, with one end fitted inside the second end of the mounting cylinder 2, and the outer wall of the drive cylinder 123 rotatably connected to the mounting cylinder 2. The drive cylinder 123 is fitted outside the monitoring lens 11. The lens fixing cylinder 124 is fitted inside the drive cylinder 123, and the outer wall of the lens fixing cylinder 124 is provided with an external thread, while the inner wall of the drive cylinder 123 is provided with an internal thread that matches the external thread. The lens 121 is fixed to the end of the lens fixing cylinder 124 away from the monitoring lens 11. The inner wall of the lens fixing cylinder 124 is provided with a sliding groove along the axial direction of the lens fixing cylinder 124, and a sliding strip is fixed to the outer periphery of the monitoring lens 11, with the sliding strip slidingly engaging with the sliding groove. The output shaft of the third motor 122 is connected to the outer wall of the drive cylinder 123 through a transmission assembly, so as to drive the drive cylinder 123 to rotate relative to the mounting cylinder 2. By setting a third motor 122, the third motor 122 and the drive cylinder 123 are connected in a transmission manner, and the drive cylinder 123 and the mounting cylinder 2 are slidably connected. Specifically, the outer wall of the drive cylinder 123 is provided with an annular groove, and the edge of the oblique section 22 of the mounting cylinder 2 is provided with an inwardly protruding annular slide rail. The annular groove and the annular slide rail cooperate to make the drive cylinder 123 and the mounting cylinder 2 rotatably connected, realizing the relative rotation of the drive cylinder 123 and the mounting cylinder 2 under the driving action of the third motor 122. Specifically, a bevel gear 41 is fitted on the output shaft of the third motor 122, and a bevel gear ring 23 is fixed on the outer wall of the drive cylinder 123. The meshing of the bevel gear 41 and the bevel gear ring 23 realizes the driving of the drive cylinder 123 by the third motor 122. In this embodiment, the third motor 122 is set in the space surrounded by the second mounting structure 32, the mounting cylinder 2, and the fixing plate 21. The output shaft of the third motor 122 passes through the fixing plate 21, and the bevel gear 41 is located at the second end of the mounting cylinder 2. In some other embodiments, the third motor 122 may also be located outside the mounting cylinder 2. The lens fixing cylinder 124 is fitted inside the drive cylinder 123. Through the cooperation of the sliding groove and the sliding strip, the lens fixing cylinder 124 can only move in the direction of relative sliding of the sliding groove and the sliding strip. Therefore, when the third motor 122 drives the drive cylinder 123 to rotate, the internal thread drives the external thread to rotate, and then the lens fixing cylinder 124 moves in the direction of relative sliding of the sliding groove and the sliding strip, forming a transmission form similar to a lead screw and slider structure to achieve linear drive. The forward and reverse rotation of the third motor 122 enables the lens 121 mounted on the lens fixing cylinder 124 to move closer to or away from the monitoring lens 11. In some other embodiments, the lens mounting structure can also be directly driven by the drive motor to enable the lens 121 to move closer to or away from the monitoring lens 11. In this embodiment, the sliding groove is formed on the inner wall surface of the lens fixing cylinder 124. In some other embodiments, the sliding groove can also be embedded in the inner wall of the lens fixing cylinder 124.

One or more monitoring devices 100 can be installed; in this embodiment, multiple monitoring devices 100 are installed, forming a distributed monitoring system. The visual blind spots of the distributed monitoring system are further reduced, and the control system enables the acquisition directions of multiple monitoring devices 100 to overlap, further avoiding the formation of blind spots and thus preventing property damage and personal injury caused by damage to the monitoring devices 100. The monitoring system provided in this embodiment can be applied to substations. Since substations are assemblies of equipment used to disconnect or connect, change, or adjust voltage, they are the convergence points of power transmission and distribution in the power system.
