Description

Technical Field

[0001] This invention belongs to the technical field of road monitoring facilities, and specifically relates to a mobile monitoring device for highways. Background Technology

[0002] Highways bring great convenience to people's lives and are the first choice for self-driving travel. However, occupying the emergency lane can easily cause traffic accidents. After an accident, some drivers use the emergency lane, which can also cause congestion and hinder rescue vehicles from reaching the scene. Currently, highway traffic management departments mainly rely on manual labor and fixed monitoring equipment to collect evidence of illegal use of emergency lanes on highways, resulting in limited evidence collection capacity and low efficiency.

[0003] Currently, some provincial and municipal highway traffic management departments are using drones for patrols in harsh environments such as high temperatures, wind, rain, radiation, and high altitudes. This helps them to quickly grasp road conditions, detect accident scenes and congestion points, and collect information on violations. However, these drones are expensive to manufacture, require the cooperation of remote control terminals and ground stations to complete reconnaissance missions, are susceptible to external interference affecting their use, and have limited endurance and cruising radius, thus restricting their widespread application.

[0004] In addition, there are some reports about highway patrol vehicles. These vehicles are equipped with wheels and drive motors. When in operation, the drive motors rotate the wheels, and the vehicle moves along the highway guardrail. The structure of highway guardrails mainly consists of posts and steel guardrail panels. The inner side of the guardrail panels has one or more corrugated sections that curve vertically. Due to collisions with the guardrails caused by traffic accidents, existing guardrails are deformed to varying degrees, especially the inner side of the guardrail panels directly facing vehicles, making it difficult to maintain a continuous and smooth transition in the direction of vehicle travel. Therefore, when these highway patrol vehicles move along the highway guardrails, they experience significant bumps and are easily hindered by guardrail deformation, sometimes even becoming unable to move. Summary of the Invention

[0005] This invention aims to solve the problem of guardrail deformation or damage caused by traffic accident collisions obstructing the movement of highway patrol vehicles.

[0006] The present invention provides the following technical solution: a mobile monitoring device for highways, comprising a guide rail installed on a highway guardrail, a moving mechanism mounted on the guide rail and movable along the guide rail, and a monitoring device mounted on the moving mechanism; the guide rail is located outside the road of the guardrail, and the guide rail is connected to the guardrail through several independent buffer mechanisms, the several buffer mechanisms being distributed along the length of the guide rail, the buffer mechanisms being able to compress from the side of the guardrail to the side of the guide rail, the buffer mechanism at the location where the guardrail collapses due to a local impact is compressed, absorbing the impact on the guide rail, and the guide rail maintaining its working state under the support of the buffer mechanisms at non-impact positions.

[0007] Furthermore, the buffer mechanism includes a fixed rod mounted on the guardrail and a sleeve rod slidably connected to the fixed rod. The sleeve rod has a hollow cylindrical structure. One end of the fixed rod is fixed to the guardrail, and the other end is slidably connected to the sleeve rod. A guide rail is fixedly connected to the sleeve rod, and a spring is provided between the sleeve rod and the fixed rod.

[0008] Furthermore, the sleeve rod and the fixed rod are connected by a quick-release structure, which includes a slide rod and a connector coaxially connected to the slide rod; the slide rod is coaxial with the sleeve rod and slidably mounted on the sleeve rod, and a spring is located between the slide rod and the sleeve rod; one end of the connector is threaded to the end of the slide rod away from the sleeve rod, and the other end of the connector is threaded to the end of the fixed rod; the slide rod has a cavity that allows the connector to fully enter, and the connector is connected to a rotary drive component outside the slide rod.

[0009] Furthermore, one end of the slide rod has a stepped cylindrical cavity with a small opening and a large interior. The connector is nested inside the cavity. The small diameter section of the stepped cylindrical cavity is threaded, and the connector is threaded to the small diameter section. The large diameter section of the stepped cylindrical cavity is a smooth hole, and the connector slides in contact with the large diameter section. The wall of the large diameter section has a spiral groove that connects the inside and outside. The spiral direction and pitch of the spiral groove are the same as the thread on the connector. A knob is fitted on the slide rod, and a rod connected to the knob passes through the spiral groove and connects to the connector. When the knob is rotated, the connector rotates synchronously and moves axially.

[0010] Furthermore, the guide rail is an I-shaped guide rail, with one end of the sleeve rod fixed to the vertical side wall of the I-shaped guide rail, and the moving mechanism is slidably mounted on the I-shaped guide rail; the moving mechanism is a moving trolley, which has several drive wheels that contact the top and bottom of the guide rail, and several guide grooves extending along the length of the guide rail are provided on the top and bottom of the guide rail, with the drive wheels of the moving trolley located in the guide grooves.

[0011] Furthermore, a guide groove cleaning mechanism is provided on both sides of the moving trolley in the direction of movement; the guide groove cleaning mechanism includes cleaning rods provided on both sides of the moving trolley in the direction of movement and guide plates provided on the cleaning rods. The number of cleaning rods on both sides corresponds to the number of guide grooves. The cleaning rods have a cleaning end that extends into the guide groove and is close to the surface of the guide groove. The cleaning end has an inclined surface that extends upward from the bottom of the guide groove.

[0012] Furthermore, the mobile trolley is equipped with a lifting mechanism, and the monitoring device is installed on the lifting mechanism; the lifting mechanism includes a control motor installed on the mobile trolley, a gear driven and connected to the output end of the control motor, a guide sleeve installed on one side of the mobile trolley, a movable rod passing through the guide sleeve and slidably connected to the guide sleeve, and a rack corresponding to the gear installed on the movable rod, with the gear meshing with the rack.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] This invention provides a mobile monitoring device for highways. The guide rail is indirectly mounted on the guardrail via a buffer mechanism. When the guardrail is impacted, it collapses towards the guide rail. The elastic deformation of the springs inside the buffer mechanism compresses the buffer mechanism, absorbing the impact potential energy and reducing or eliminating its impact on the guide rail. The buffer mechanisms are independent of each other; when a certain part of the guardrail is impacted, only the buffer mechanism connected to the deformation area of ​​the guardrail is compressed, while buffer mechanisms at other locations maintain the working posture of the guide rail. The parts of the buffer mechanism connected to the guardrail and the parts connected to the guide rail are combined via a quick-release structure, allowing the buffer mechanism to be quickly disconnected or reassembled at the quick-release structure for easy replacement of damaged parts of the guardrail.

Detailed Implementation

[0022] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0023] like Figure 1-6As shown: A mobile monitoring device for highways includes a guide rail 2 installed on a highway guardrail 1, a moving mechanism that can move along the guide rail 2, and a monitoring device 4 installed on the moving mechanism; the monitoring device 4 moves along the guide rail 2 under the drive of the moving mechanism to take pictures of vehicles on the highway.

[0024] The guide rail 2 shown in the figure is a portion of a section of guardrail 1, and its length is not limited to the length and scale shown in the figure. The guide rail 2 is located on the outside of the guardrail 1. The guide rail 2 is connected to the guardrail 1 through several independent buffer mechanisms. The buffer mechanisms are distributed along the length of the guide rail 2. The buffer mechanisms can be compressed from the side of the guardrail 1 to the side of the guide rail 2. When the guardrail 1 is partially impacted and the buffer mechanism at the location where the guide rail 2 collapses is compressed, the impact on the guide rail 2 is absorbed. The guide rail 2 maintains its working state under the support of the buffer mechanisms at non-impact locations.

[0025] The buffer mechanism includes a fixed rod 1.1 mounted on the guardrail 1 and a sleeve rod 1.2 slidably connected to the fixed rod 1.1. The sleeve rod 1.2 is a hollow cylindrical structure. One end of the fixed rod 1.1 is fixed to the guardrail 1, and the other end is slidably connected to the sleeve rod 1.2. The guide rail 2 is fixedly connected to the sleeve rod 1.2, and a spring 1.4 is installed between the sleeve rod 1.2 and the fixed rod 1.1. When a certain amount of external force is applied to the sleeve rod 1.2, the spring 1.4 is used to suppress the relative displacement between the sleeve rod 1.2 and the fixed rod 1.1, thereby preventing the guide rail 2 from shifting under a certain external force, thus avoiding the problem of unclear photos caused by the displacement of the guide rail 2 when the monitoring equipment is taking pictures.

[0026] When a portion of the guardrail 1 is impacted and deforms outward toward the road, the fixed rod 1.1 at the deformed point moves inward toward the sleeve rod 1.2 under the influence of the guardrail 1 deformation, providing a buffer against the deformation of the guardrail 1 and preventing the guide rail 2 from deforming due to the deformation of the guardrail 1. The spring 1.4 is compressed inward toward the sleeve rod 1.2 by the pressure of the fixed rod 1.1. The buffer mechanism ensures that the monitoring equipment is not affected by the deformation of the guardrail 1, allowing the monitoring equipment to continue moving on the guide rail 2. Since the guardrail 1 is only partially deformed, the fixed rod 1.1 and sleeve rod 1.2 located outside the deformed point of the guardrail 1 do not move. The guide rail 2, supported by the other sleeve rods 1.2 and fixed rod 1.1, will not be displaced by the compressed spring 1.4, further avoiding the problem of unclear photos caused by the displacement of the guide rail 2 when the monitoring equipment is taking pictures.

[0027] like Figure 3As shown: The guide rail 2 is an I-shaped guide rail 2. One end of the sleeve rod 1.2 is fixed on the vertical side wall of the I-shaped guide rail 2. The moving mechanism is slidably set on the I-shaped guide rail. The moving mechanism can be a moving trolley 3. The moving trolley 3 has several drive wheels that contact the top and bottom of the guide rail 2. Several guide grooves 2.1 extending along the length of the guide rail 2 are opened at the top and bottom of the guide rail 2. The drive wheels of the moving trolley 3 are located in the guide grooves 2.1. Driven by the drive wheels, the moving trolley 3 moves along the guide rail 2.

[0028] The aforementioned monitoring device 4 is mounted on a mobile trolley 3. The movement of the mobile trolley 3 moves the monitoring device 4 to capture images of vehicles on the highway.

[0029] like Figure 3 As shown: Guide groove cleaning mechanisms are provided on both sides of the moving trolley 3 in the direction of movement. The guide groove cleaning mechanisms are used to prevent impurities such as fallen leaves and dust from accumulating in the guide groove 2.1, so as to avoid the impurities in the guide groove 2.1 from affecting the movement of the moving trolley 3.

[0030] like Figure 3-4 As shown: The guide groove cleaning mechanism includes cleaning rods 3.6 on both sides of the moving trolley 3 in the direction of movement, and guide plates 3.7 on the cleaning rods 3.6. The number of cleaning rods 3.6 on both sides corresponds to the number of guide grooves 2.1. The cleaning rods 3.6 have cleaning ends that extend into the guide grooves 2.1 and are close to the surface of the guide grooves 2.1. The cleaning ends are wedge-shaped and have inclined surfaces that extend upward from the bottom of the guide grooves 2.1. When the cleaning ends are moved by the moving trolley 3 into the guide grooves 2.1 and come into contact with impurities in the grooves, the impurities are squeezed out of the guide grooves 2.1 by the pressure of the inclined surfaces of the cleaning ends. The impurities squeezed out of the guide grooves 2.1 then come into contact with the moving guide plates 3.7. Under the guidance of the guide plates 3.7, the impurities are removed from the guide rails 2.

[0031] The mobile trolley 3 is equipped with a lifting mechanism, and the monitoring device 4 is mounted on the lifting mechanism. The lifting mechanism can adjust the height of the monitoring device 4 up and down, allowing the monitoring device 4 to capture images of vehicles on the road from multiple angles. Specifically, the lifting mechanism includes a control motor 3.1 mounted on the mobile trolley 3, a gear 3.5 driven and connected to the output end of the control motor 3.1, a guide sleeve 3.2 mounted on one side of the mobile trolley 3, and a movable rod 3.3 passing through and slidably connected to the guide sleeve 3.2. The movable rod 3.3 is equipped with a rack 3.4 corresponding to the gear 3.5, and the gear 3.5 meshes with the rack 3.4. The monitoring device 4 is mounted on the upper end of the movable rod 3.3. When adjusting the height, the control motor 3.1 drives the gear 3.5 to rotate, and the gear 3.5 drives the movable rod 3.3 up and down through the rack 3.4, thereby adjusting the height of the monitoring device 4.

[0032] like Figure 3As shown: The mobile trolley 3 is also equipped with another guide sleeve 3.2, and two guide grooves 2.1 are set correspondingly above and below. The movable rod 3.3 slides through the two guide grooves 2.1 on the mobile trolley 3. When the mobile trolley 3 brakes during movement and the lifting mechanism adjusts the monitoring device 4 to a higher position, the movable rod 3.3 will usually shake due to inertia. The shaking of the movable rod 3.3 will cause the monitoring device 4 to shake. When the monitoring device 4 is in the shooting state, the shaking will affect the shooting of the monitoring device 4 and make the captured image blurry. The setting of the two guide sleeves 3.2 can restrict the movable rod 3.3 from both the top and bottom, enhance the stability of the movable rod 3.3, reduce the shaking of the movable rod 3.3 caused by inertia, and thus enhance the stability of the shooting of the monitoring device 4.

[0033] The present invention also includes a quick-release structure, which is set between the sleeve rod 1.2 and the fixed rod 1.1. When the deformed guardrail 1 needs to be replaced, the quick-release structure facilitates the separation of the sleeve rod 1.2 and the fixed rod 1.1, so that maintenance personnel can quickly remove the deformed guardrail 1.

[0034] like Figure 5-6 As shown: The quick-release structure includes a slide rod 1.3 and a connecting piece 1.5 coaxially arranged with the slide rod 1.3. The slide rod 1.3 is coaxial with the sleeve rod 1.2 and slidably mounted on the sleeve rod 1.2. The spring 1.4 mentioned above is located between the slide rod 1.3 and the sleeve rod 1.2. One end of the connecting piece 1.5 is threadedly connected to the end of the slide rod 1.3 away from the sleeve rod 1.2, and the other end of the connecting piece 1.5 is threadedly connected to the end of the fixing rod 1.1. The slide rod 1.3 has a structure that allows the connecting piece 1.5 to fully... The connector 1.5 enters the cavity and is connected to the rotating drive component outside the slide rod 1.3. When the connector 1.5 is rotated, it moves on the slide rod 1.3 under the action of being threadedly connected to the slide rod 1.3. When the connector 1.5 approaches the fixed rod 1.1, it is threadedly connected to the fixed rod 1.1 and also to the slide rod 1.3. When the connector 1.5 is detached from the fixed rod 1.1, it is completely inserted into the cavity of the slide rod 1.3, completing the quick disassembly of the fixed rod 1.1 and the sleeve rod 1.2.

[0035] like Figure 6As shown: One end of the slide rod 1.3 has a stepped cylindrical cavity with a small opening and a large interior. The connector 1.5 is nested inside the cavity. The small diameter section of the stepped cylindrical cavity is threaded, and the connector 1.5 is threaded to the small diameter section. The large diameter section of the stepped cylindrical cavity is a smooth hole, and the connector 1.5 slides in contact with the large diameter section. The wall of the large diameter section has a spiral groove 1.3.1 that connects the inside and outside. The spiral direction and pitch of the spiral groove 1.3.1 are the same as the thread on the connector 1.5, so that the knob 1.6 and the connector 1.5 can move axially synchronously without interfering with each other. A knob 1.6 is fitted on the slide rod 1.3. The rod connected to the knob 1.6 passes through the spiral groove 1.3.1 and connects to the connector 1.5. When the knob 1.6 rotates, the connector 1.5 rotates synchronously and moves axially.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
