[0036] Currently, monitors 200 used to monitor road and vehicle conditions on highways are mounted on the roadside via brackets. When a monitor 200 becomes damaged or needs to be replaced for other reasons, workers use scaffolding to reach the height of the monitor 200 and perform high-altitude repairs and replacements. This high-altitude work is dangerous and difficult, reducing efficiency.

[0037] See also Figure 1-Figure 4 In view of this, the designer designed an intelligent detection device for highways. By adjusting the shape of the base frame 100 to lower the height of the monitor 200, workers do not need to perform high-altitude operations, which reduces the difficulty of operations, improves operation safety, and improves operation efficiency.

[0038] It should be noted that, in the following embodiments, unless otherwise specified, the first direction is the direction of arrows ab, and the second direction is the direction of arrows ba.

[0039] In this embodiment, the high-altitude highway intelligent monitoring device includes a basic frame 100 and a monitor 200. The basic frame 100 includes a folding frame 110 and a mounting rod 120. The folding frame 110 includes a first rod 111, a second rod 112, and a third rod 113 that are rotatably connected in sequence. The first rod 111 and the second rod 112 are unlockably connected through a first locking assembly 300. When the first locking assembly 300 is locked, the first rod 111 and the second rod 112 remain relatively fixed. When the first locking assembly 300 is unlocked, the first rod 111 and the second rod 112 remain relatively fixed. 11 and the second rod 112 can rotate relative to each other around the first axis; the second rod 112 and the third rod 113 are unlockably connected by the second locking assembly 400. When the second locking assembly 400 is locked, the second rod 112 and the third rod 113 remain relatively fixed. When the second locking assembly 400 is unlocked, the second rod 112 and the third rod 113 can rotate relative to each other around the second axis; wherein the extension direction of the first axis and the second axis is the same; the first rod 111 is used to be fixed to the ground, and the mounting rod 120 is connected to the third rod 113.

[0040] In this embodiment, the intelligent highway monitoring device is installed on the side of the highway. A first rod 111 is fixed to the ground and positioned approximately vertically. A mounting rod 120 extends along the width of the highway, allowing the camera to capture information about vehicles traveling on the highway and road conditions. When the camera needs to be repaired, the first locking assembly 300 and the second locking assembly 400 are operated to release the first and second rods 111, 112, allowing them to rotate about a first axis. Simultaneously, the second locking assembly 400 is released from the second and third rods 112, 113, allowing them to rotate about a second axis. Rotating the second and third rods 112, 113, lowers the height of the mounting rod 120 connected to the third rod 113, thereby lowering the height of the camera mounted on the mounting rod 120. This eliminates the need for overhead work, reduces maintenance effort, and improves maintenance efficiency and safety. At the same time, the angle of the first rod 111 is kept unchanged, the second rod 112 is set to be rotated along the first direction, and while the second rod 112 is rotated, the second rod 112 is rotated relative to the third rod 113 along a second direction opposite to the first direction. The first rod 111, the second rod 112 and the third rod 113 can be in a "Z" shape, and because the first rod 111 is vertically arranged, the third rod 113 can be kept from rotating during the height reduction process, that is, the mounting rod 120 and the camera are only gradually lowered in height without rotating, thereby reasonably utilizing the longitudinal space while avoiding the situation where the mounting rod 120 rotates and interferes with the surrounding environment, and the maintenance process is safer.

[0041] In this embodiment, the first rod 111, the second rod 112, and the third rod 113 are optionally configured as circular rods, that is, the cross-sectional outer contours of the first rod 111, the second rod 112, and the third rod 113 are all circular. Obviously, in other embodiments, the cross-sectional shapes of the first rod 111, the second rod 112, and the third rod 113 can also be configured as square rods, etc. The first rod 111 is provided with a first rotating head at one end, the second rod 112 is provided with a second rotating head at one end, and a first rotating plate at the other end, and the third rod 113 is provided with a second rotating plate at one end. The first rotating head of the first rod 111 is hingedly connected to the first rotating plate of the second rod 112, and the second rotating head of the second rod 112 is hingedly connected to the second rotating plate of the third rod 113. A mounting base is provided at the end of the first rod 111 away from the second rod 112. The first rod 111 is welded to the mounting base.

[0042] Furthermore, a first clip 310 is provided on the outer wall of the first rod 111. The first clip 310 is an "L"-shaped plate. One end of the first clip 310 is fixedly connected to the outer wall of the first rod 111, and the other end of the first clip 310 is spaced apart from the outer wall of the first rod 111. The first clip 310 and the first rod 111 together define a first slot 320. The outer wall of the first rod 111 is also provided with a first positioning groove 1111. The first positioning groove 1111 is configured as a dovetail groove or a "T"-shaped groove. The first positioning groove 1111 extends along the circumference of the first rod 111, and one end of the first positioning groove 1111 extends to a position spaced apart from the rotational intersection of the first rod 111 and the second rod 112 in the circumferential direction of the first rod 111.

[0043] Furthermore, a second clip plate 330 and a third clip plate 410 are provided on the outer wall of the second rod 112. The second clip plate 330 and the third clip plate 410 are evenly spaced apart around the circumference of the second rod 112. The second clip plate 330 and the third clip plate 410 are respectively located near the ends of the second rod 112. Specifically, the second clip plate 330 is located near the first clip plate 310, that is, the second clip plate 330 is located between the first clip plate 310 and the third clip plate 410. The second clip plate 330 and the first clip plate 310 are evenly spaced apart around the circumference of the first rod 111. The second clip plate 330 and the third clip plate 410 are both configured as "L"-shaped plates. The second clip plate 330 and the second rod 112 jointly define a second slot 340, and the third clip plate 410 and the second rod 112 jointly define a third slot 420. The outer wall of the second rod 112 is further provided with a second positioning groove 1121 and a third positioning groove 1122. Both the second positioning groove 1121 and the third positioning groove 1122 extend along the circumference of the second rod 112. The second positioning groove 1121 corresponds to the position of the second engaging groove 340, and the third positioning groove 1122 corresponds to the position of the third engaging groove 420. One end of the second positioning groove 1121 extends to a position spaced apart from the rotational intersection of the first rod 111 and the second rod 112 in the circumferential direction of the second rod 112. One end of the third positioning groove 1122 extends to a position spaced apart from the rotational intersection of the second rod 112 and the third rod 113 in the circumferential direction of the second rod 112.

[0044] Furthermore, a fourth retaining plate 430 is provided on the outer wall of the third rod 113. The fourth retaining plate 430 is an L-shaped plate. One end of the fourth retaining plate 430 is fixedly connected to the outer wall of the third rod 113, and the other end of the fourth retaining plate 430 is spaced apart from the outer wall of the third rod 113. The fourth retaining plate 430 and the third rod 113 together define a fourth retaining groove 440. The outer wall of the third rod 113 is also provided with a fourth positioning groove 1131. The fourth positioning groove 1131 is configured as a dovetail groove or a T-shaped groove. The fourth positioning groove 1131 extends along the circumference of the third rod 113, and one end of the fourth positioning groove 1131 extends to a position spaced apart from the rotational intersection of the second rod 112 and the third rod 113 on the circumference of the third rod 113. In addition, the fourth clamping plate 430 and the third clamping plate 410 are evenly spaced apart in the circumferential direction of the second rod 112 or the third rod 113. It should be understood that when the first rod 111, the second rod 112 and the third rod 113 are coaxial, the first clamping plate 310, the third clamping plate 410, the first positioning groove 1111 and the third positioning groove 1122 are located on the same side, and the second clamping plate 330, the second positioning groove 1121, the fourth clamping plate 430 and the fourth positioning groove 1131 are located on the same side.

[0045] In this embodiment, optionally, the first locking assembly 300 includes a first locking member 301 and a second locking member 302, and the first rod 111 and the second rod 112 are unlockably connected through the first locking member 301 and the second locking member 302; when the first locking member 301 is in a locked state and the second locking member 302 is in an unlocked state, the second rod 112 can rotate unidirectionally in a first direction relative to the first rod 111; when the second locking member 302 is in a locked state and the first locking member 301 is in an unlocked state, the second rod 112 can rotate unidirectionally in a second direction opposite to the first direction relative to the first rod 111. Specifically, the first locking piece 301 and the first positioning slot 1111 are slidably engaged in the circumferential direction of the first rod 111, and the first locking piece 301 can switch between a first position in which it is engaged with the first slot 320 and a second position in which it is disengaged from the first slot 320; and when in the first position, the first locking piece 301 and the outer wall of the second rod 112 abut against and block the rotational intersection line of the first rod 111 and the second rod 112, so as to limit the second rod 112 from rotating in the second direction relative to the first rod 111, that is, to enable the second rod 112 to rotate unidirectionally in the first direction relative to the first rod 111. The second locking piece 302 is slidably engaged with the second positioning slot 1121 along the extension direction of the second positioning slot 1121, so that the second locking piece 302 can switch between a third position in which it is engaged with the second slot 340 and a fourth position in which it is disengaged from the second slot 340. When in the third position, the second locking piece 302 abuts against the outer wall of the first rod 111 and blocks the rotational intersection line of the first rod 111 and the second rod 112, so as to limit the second rod 112 from rotating in the first direction relative to the first rod 111, that is, the second rod 112 can rotate unidirectionally in the second direction relative to the first rod 111.

[0046] Optionally, the second locking assembly 400 includes a third locking piece 401 and a fourth locking piece 402, and the second rod 112 and the third rod 113 are unlockably connected through the third locking piece 401 and the fourth locking piece 402; when the third locking piece 401 is in a locked state and the fourth locking piece 402 is in an unlocked state, the third rod 113 can rotate unidirectionally in a first direction relative to the second rod 112; when the fourth locking piece 402 is in a locked state and the third locking piece 401 is in an unlocked state, the third rod 113 can rotate unidirectionally in a second direction opposite to the first direction relative to the second rod 112. Specifically, the third locking piece 401 is slidably engaged with the third positioning slot 1122 on the second rod 112 along the circumferential direction of the third positioning slot 1122, so that the third locking piece 401 can switch between a fifth position in which it is engaged with the third slot 420 and a sixth position in which it is disengaged from the third slot 420; and when in the fifth position, the third locking piece 401 abuts against the outer wall of the third rod 113 and can block the rotational intersection line of the second rod 112 and the third rod 113, so as to limit the third rod 113 from rotating in the second direction relative to the second rod 112, that is, the third rod 113 can rotate unidirectionally in the first direction relative to the second rod 112. The fourth locking piece 402 is slidably engaged with the fourth positioning slot 1131 on the third rod 113 along the circumferential direction of the fourth positioning slot 1131, so that the fourth locking piece 402 can switch between a seventh position in which it is engaged with the fourth slot 440 and an eighth position in which it is disengaged from the fourth slot 440. When in the seventh position, the fourth locking piece 402 abuts against the outer wall of the second rod 112 and blocks the rotational intersection line of the second rod 112 and the third rod 113, so as to limit the third rod 113 from rotating in the first direction relative to the second rod 112, that is, to enable the third rod 113 to rotate unidirectionally in the second direction relative to the second rod 112.

[0047] In this embodiment, the mounting base is fixed to the roadside, and the first axis and the second axis extend along the width direction of the highway. During normal operation, the first rod 111, the second rod 112 and the third rod 113 are locked by the first locking assembly 300 and the second locking assembly 400, and the folding frame 110 remains in a vertical state and will not fold. When the height of the monitor 200 needs to be lowered, the first locking assembly 300 and the second locking assembly 400 are operated to lower the height of the third rod 113. During the lowering process, the third rod 113 can always remain in a vertical state and will not rotate to abut against the ground, thereby preventing the monitor 200 from being damaged. In addition, the third rod 113 can be selected to be located on the left or right side of the first rod 111 after it is lowered, so as to adjust the position of the third rod 113 according to the on-site environment, rationally utilize space, and facilitate the maintenance of the monitor 200. Figure 3As shown, for example, when the third rod 113 is required to be on the left side of the first rod 111 after being lowered, the second locking member 302 and the third locking member 401 are in the unlocked state, and the first locking member 301 and the fourth locking member 402 are in the locked state. At this time, the second rod 112 can only rotate in the first direction relative to the first rod 111, and the third rod 113 can only rotate in the second direction relative to the second rod 112. In this way, the rotation direction of the second rod 112 and the third rod 113 is limited, and the third rod 113 must be located on the left side of the first rod 111 after being rotated. It is less likely to cause misoperation during operation, and it is convenient for the third rod 113 to be lowered. At the same time, when the second rod 112 rotates in the first direction, the second clamping plate 330 can abut against the first rod 111, thereby limiting the rotation range of the second rod 112 and stabilizing the action of the second rod 112. At this time, the second rod 112 is roughly in a horizontal state; similarly, the third rod 113 can abut against the third clamping plate 410 to make the third rod 113 in a vertical state. Figure 4 As shown, for example, when the third rod 113 is required to be positioned to the right of the first rod 111 after being lowered, the second locking member 302 and the third locking member 401 are locked, and the first locking member 301 and the fourth locking member 402 are unlocked. At this time, the second rod 112 can only rotate in the second direction relative to the first rod 111, and the third rod 113 can only rotate in the first direction relative to the second rod 112. In this way, the rotation directions of the second and third rods 112 and 113 are limited, and the third rod 113 is inevitably positioned to the right of the first rod 111 after rotation. This reduces the possibility of misoperation during operation and facilitates the lowering of the third rod 113. It should be understood that the left and right sides of the first rod 111 are merely for ease of description and are illustrated in the figures. When the reference direction changes, the position of the third rod 113 relative to the first rod 111 changes.

[0048] In other embodiments, the mounting rod 120 and the third rod 113 are rotatably connected about a third axis, with the third axis being colinear with the axis of the third rod 113. For example, a motor is provided on the third rod 113, and the mounting rod 120 is connected to the output shaft of the motor, so that the motor can drive the mounting rod 120 to rotate relative to the third rod 113. In this manner, the mounting rod 120 can rotate relative to the third rod 113, and the first rod 111, the second rod 112, the third rod 113, and the mounting rod 120 can be positioned in the same plane. In other words, the folding stand 110 occupies a two-dimensional space instead of a three-dimensional space, thereby reducing the occupied space. This facilitates lowering the monitor 200 to a suitable position using the folding stand 110 in a limited space, facilitating maintenance of the monitor 200 and enhancing safety.

[0049] The intelligent highway monitoring device provided in this embodiment can lower the height of the monitor 200, and the direction is determined during the lowering process, which is less likely to cause misoperation, and the entire maintenance process is safe and reliable.

[0050] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
