Description

Technical Field

[0001] This utility model belongs to the field of monitoring equipment technology, specifically relating to a highway lane-level traffic flow monitoring device. Background Technology

[0002] Traffic flow monitoring cameras, as core components of traffic monitoring systems, play a crucial role in real-time collection of traffic flow data, dynamic analysis of traffic conditions, and providing scientific decision-making support for traffic management departments. In highway scenarios, these devices are typically deployed according to traffic engineering specifications to achieve continuous monitoring of traffic parameters across the entire road segment. However, due to the influence of highway greening designs, tall trees are often planted on slopes and in the median strip. Under extreme weather conditions, there may be risks such as broken branches and falling debris, which could lead to mechanical impact damage to the monitoring cameras. Although some existing devices have been equipped with basic protective structures, their protection systems still have limitations, specifically in terms of incomplete protection range, insufficient impact resistance, and poor environmental adaptability. These limitations may also negatively impact key performance parameters such as the camera's field of view and heat dissipation efficiency. Therefore, it is urgent to develop a new type of protective device with omnidirectional protection, high impact resistance, and environmental adaptability through structural optimization and material innovation to improve the operational stability and data reliability of traffic flow monitoring cameras under complex working conditions.

[0003] Chinese patent CN219221746U discloses a highway traffic volume monitoring device, including a monitoring device limiting sleeve. A camera is movably fitted inside the monitoring device limiting sleeve. A telescopic rod is installed on the upper part of the monitoring device limiting sleeve, and a protective baffle is fixedly connected to the upper part of the telescopic rod. A damping spring is movably fitted onto the upper part of the protective baffle. This highway traffic volume monitoring device uses a buffer protective plate installed on top of the protective baffle. The buffer protective plate buffers passing impurities, preventing excessive impact on the camera and thus avoiding damage. Simultaneously, the protective baffle further protects the upper part of the camera, preventing impurities from accumulating there. Furthermore, during the telescopic adjustment of the buffer protective plate, the inclined telescopic rod and the inclined telescopic sleeve continuously support the position of the buffer protective plate, increasing its stability during adjustment.

[0004] However, although the above-mentioned technical solution can provide a certain degree of protection for the camera equipment, the buffer plate set on top only blocks and buffers foreign objects coming from above. However, the flight state of foreign objects is difficult to determine in bad weather. This can cause foreign objects to easily hit the sides, front or back of the camera equipment during flight. Prolonged impacts can still damage the camera equipment, resulting in the interruption of the use of the camera equipment. Therefore, it has certain limitations in use. Utility Model Content

[0022] 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.

[0023] Example 1:

[0024] Please see Figures 1 to 5As shown, a highway lane-level traffic flow monitoring device includes a mounting plate 1. A camera 2 is fixedly connected to the middle of the top of the mounting plate 1. A top plate 3 is provided above the camera 2. Two first guide grooves 4 are opened on both sides of the top of the mounting plate 1. A side plate 5 is slidably connected inside the first guide groove 4. A connecting strip 6 is fixedly connected to the top of the surface of the side plate 5. A second guide groove 7 is opened inside the connecting strip 6. A sliding block 8 is slidably connected inside the second guide groove 7. Guide rods 9 slide through both sides of the top of the top of the top plate 3. The bottom end of the guide rod 9 is fixedly connected to the top of the sliding block 8. A blocking disc 10 is fixedly connected to the bottom of the surface of the guide rod 9. A first damping spring 11 is fixedly connected to the top of the blocking disc 10. The top end of the first damping spring 11 is fixedly connected to the bottom of the top plate 3.

[0025] Camera 2 is existing technology used to monitor road traffic flow, and will not be described in detail. Mounting plate 1 facilitates the fixing of camera 2. The opening of the first guide groove 4 allows the side plate 5 to slide inside it. There are two side plates 5, both of which slide inside the first guide groove 4. The side plate 5 allows the connecting strip 6 to be fixed to the top of its surface, thereby facilitating the opening of the second guide groove 7. The opening of the second guide groove 7 allows the sliding block 8 to slide inside it. The guide rod 9 provides a certain guiding effect when the top plate 3 is hit by foreign objects. The first damping spring 11 provides a certain buffering effect. The first damping spring 11 is composed of a damping block and a buffer spring. The blocking plate 10 facilitates the installation and fixing of the first damping spring 11.

[0026] A positioning plate 12 is fixedly connected to one side of the top center of the mounting plate 1. Five second damping springs 13 are fixedly connected to both ends of one side of the positioning plate 12. A buffer plate 14 is fixedly connected to the end of the second damping spring 13 away from the positioning plate 12. The positioning plate 12 is designed to fix the second damping springs 13 to both ends of one side, and the buffer plate 14 provides a certain degree of blocking and buffering effect when a foreign object hits one side of the camera 2.

[0027] The top and bottom of both ends of the positioning plate 12 are provided with third guide grooves 15. A fixing rod 16 is fixedly connected to one side of the inner wall of the third guide groove 15, and a third damping spring 17 is fixedly connected to one side of the inner wall of the third guide groove 15. The third damping spring 17 is sleeved on the surface of the fixing rod 16. The opening of the third guide groove 15 allows the fixing rod 16 and the third damping spring 17 to be fixed to one side of its inner wall. The structure of the third damping spring 17 is the same as that of the first damping spring 11, both consisting of a damping block and a buffer spring.

[0028] The surface of the fixed rod 16 is slidably fitted with a connecting plate 18, and one side of the connecting plate 18 is fixedly connected to one side of the side plate 5. The connecting plate 18 allows the side plate 5 to slide on the surface of the fixed rod 16 when sliding, thus providing a certain guiding and buffering effect.

[0029] A transparent glass 19 is provided on one side of the camera 2, and a connecting sleeve 20 is rotatably connected to the middle of the bottom of the transparent glass 19. The transparent glass 19 has a certain thickness and strength, and is chemically strengthened glass with high strength. One side of the transparent glass 19 is attached to one side of the camera 2, which serves as protection without affecting the monitoring of the camera 2. When the side plate 5 moves, the transparent glass 19 will not obstruct it, and there is a certain space between them.

[0030] The connecting sleeve 20 has an internal threaded connection to a vertical rod 21. A threaded rod 22 is fixedly connected to the bottom end of the vertical rod 21, and the surface of the threaded rod 22 is threaded into the interior of the mounting plate 1. The connecting sleeve 20 allows the vertical rod 21 to be threadedly connected to it. The threads on the vertical rod 21 are opposite to those on the threaded rod 22. The operator first screws the vertical rod 21 into the connecting sleeve 20, and then screws the threaded rod 22 into the mounting plate 1 to fix the transparent glass 19. When screwing the threaded rod 22 into the mounting plate 1, the operator only needs to pinch the connecting sleeve 20 to continuously screw the threaded rod 22 downwards until it is completely screwed into the mounting plate 1 and fixed. The connecting sleeve 20 is made of polycarbonate, which is relatively hard, has high heat resistance, and is not easily deformed.

[0031] The working principle of this utility model is as follows: After the operator installs the camera 2 in a suitable position using the mounting plate 1, in extreme weather conditions, foreign objects may impact the top, sides, front, or back of the camera 2. When the top of the camera 2 is impacted, the top plate 3 will be compressed. At this time, the top plate 3 descends via the guide rod 9, which then compresses the first damping spring 11, providing a certain buffering effect and preventing direct impact from foreign objects on the camera 2, thus protecting its top. When the front or back is impacted, the side plate 5 will be compressed, causing it to slide a certain distance through the first guide groove 4. During this process, the side plate 5 drives the positioning plate 12 and the connecting plate 18 to slide inside the third guide groove 15. Simultaneously, the connecting plate 18 slides on the surface of the fixing rod 16, causing the third damping spring... When compressed, the buffer plate 14 provides a certain degree of cushioning, protecting the front and back of the camera 2. When a foreign object impacts one side of the camera 2, the buffer plate 14 is compressed, causing the second damping spring 13 to be compressed, providing a certain cushioning effect. When impacting the other side of the camera 2, it is blocked by the transparent glass 19, providing further protection and ensuring the stability and safety of the camera 2 during use. If the transparent glass 19 is accidentally damaged, the operator will twist the vertical rod 21 while holding the connecting sleeve 20 until the threaded rod 22 is unscrewed from the inside of the mounting plate 1. Then, the operator will remove the transparent glass 19, separating it from one side of the camera 2. The vertical rod 21 will then be unscrewed from the inside of the connecting sleeve 20, and a new transparent glass 19 can be replaced.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
