Description

Technical Field

[0001] This utility model relates to the field of overload detection technology, specifically to a device for preventing vehicle violations at overload detection points at highway entrances. Background Technology

[0002] In the operation and management of highways, ensuring that vehicles meet weight regulations at entrances is a crucial aspect of guaranteeing traffic safety and the integrity of road facilities. Currently, highway entrance overload detection stations are typically equipped with various detection devices, including key components such as jacks, which are installed inside manholes to ensure their proper functioning.

[0003] However, in actual overload inspections, some violations frequently occur. Some personnel, in an attempt to evade inspection, will open the inspection wells without authorization and enter to illegally operate the jacks and related equipment, thereby affecting the accuracy of the inspection results and posing a serious threat to the safe operation of the highway.

[0004] To prevent unauthorized entry into maintenance manholes, common methods currently employed include installing locks on the manhole covers or installing surveillance cameras. Locks are chosen because they can physically prevent the manhole covers from being easily opened, are relatively inexpensive, and are easy to operate. Surveillance cameras are chosen because they allow for real-time monitoring of the manhole's condition, enabling timely action to be taken if any abnormalities are detected.

[0005] However, these existing methods have significant problems. Locks are easily cracked or pried open, offering limited security. While surveillance cameras can provide some oversight, they have blind spots and require real-time manual review, which is labor-intensive and prone to oversights. Furthermore, neither locks nor surveillance cameras can immediately trigger an alarm and take effective preventative measures the moment personnel enter the maintenance well, leading to continued violations and compromising the accuracy and impartiality of overloading detection. Utility Model Content

[0006] In view of the shortcomings of existing technologies, the technical problem solved by this utility model is to provide a device to prevent vehicles from violating regulations at the overload detection point at the entrance of the highway, which effectively solves the problem of preventing personnel from entering the maintenance well and interfering with the detection equipment.

[0007] To solve the above problems, the technical solution adopted by this utility model is: a device for preventing vehicle violations at a highway entrance overload detection point, including a weighing platform; a cavity is provided below the weighing platform, and a weighing device is installed in the cavity and connected to the weighing platform; multiple inspection wells are provided on both sides of the weighing platform, and the inspection wells are connected to the cavity. An infrared detector is installed in each inspection well, and the infrared detector is electrically connected to an alarm remotely installed in an office or duty room; a manhole cover is installed on the inspection well and connected to the inspection well; a fixing rod is provided on the manhole cover to limit and fix the manhole cover, and the two ends of the fixing rod are fixedly connected to the ground by ground locks.

[0008] The beneficial effects of this solution are as follows: Installing infrared detectors in the inspection wells on both sides of the weighing platform effectively prevents unauthorized operation of the weighing device through these wells, ensuring the authenticity and reliability of the detection data and thus improving the accuracy and impartiality of overload control detection. The well covers, secured to the ground with fixing rods and ground locks, increase the difficulty for unauthorized personnel to enter the wells, reducing the risk of equipment damage or tampering and protecting the safe and stable operation of the weighing device and detection system. The infrared detectors in the wells are electrically connected to the alarm system in the remote office or duty room. Once the detector detects an anomaly, such as an illegally opened well cover, the alarm will immediately sound, allowing staff to be promptly informed and take appropriate measures, improving the response speed and efficiency to violations. The automated monitoring and alarm system reduces the need for continuous on-site supervision; staff do not need to be constantly on-site and can handle problems promptly through remote monitoring and alarm prompts, thereby reducing labor costs.

[0009] Furthermore, a support rod is installed inside the maintenance well. The support rod has a cross-shaped structure, and an infrared detector is fixedly installed at the middle position of the support rod. The cross-shaped support rod has good stability and support force, which can provide a stable installation foundation for the infrared detector, reduce the positional displacement or shaking of the detector caused by external vibration or other interference, and ensure the accuracy and stability of its detection. The middle position can make the detection range of the infrared detector more evenly cover all directions of the maintenance well, reduce detection blind spots, and improve the comprehensiveness and reliability of detection.

[0010] Furthermore, the infrared detector is positioned at the center of the lower end face of the manhole cover, at a distance of 1-2 cm from the cover. This close proximity allows for immediate detection of changes the moment the cover is opened, enabling rapid response and effectively preventing unauthorized operations. The central position ensures balanced and accurate detection of opening actions from all directions, reducing blind spots. Maintaining a 1-2 cm distance from the cover also prevents interference from vibrations or deformations of the cover itself, ensuring stable and accurate detection signals. This relatively concealed position makes the detector less susceptible to detection and damage, increasing its safety and lifespan.

[0011] Furthermore, anti-collision posts are spaced apart on one side of the inspection well. These anti-collision posts are arranged on the side of the weighing platform to prevent vehicles from accidentally colliding with the weighing platform and the inspection well, reducing the risk of equipment damage, ensuring the normal operation of the inspection work, providing clear driving boundaries and guidance for vehicles, enabling vehicles to pass through the weighing area more properly, and reducing the possibility of vehicles deviating from the normal driving route.

[0012] Furthermore, a water guide channel is provided at the lower end of the manhole cover inside the maintenance well. This water guide channel is connected by a connecting pipe, which can effectively collect and guide rainwater or other accumulated water dripping from the manhole cover, preventing water from accumulating inside the maintenance well and avoiding soaking damage to the equipment.

[0013] Furthermore, the water guide channel is arranged in a ring around the inspection well. No matter which direction the rainwater drips or flows into the inspection well, the ring-shaped water guide channel can collect it from all directions, ensuring that no area is missed, improving the drainage effect. The accumulated water can be evenly distributed in the entire ring-shaped water guide channel, avoiding pressure concentration caused by excessive local water accumulation, and making the drainage smoother.

[0014] Furthermore, the water guide channel is positioned at the edge of the maintenance well, and the edge of the well cover is located at the center of the width of the water guide channel. This ensures that water flowing from the well cover falls directly into the water guide channel, maximizing the collection of rainwater or other accumulated water and improving drainage efficiency. The well cover edge being located at the center of the width of the water guide channel allows water flowing from the well cover to flow more concentratedly into the water guide channel, reducing the possibility of water overflowing from the edge of the water guide channel and reducing the impact of water flow on the seal between the well cover and the well opening. This helps maintain good sealing performance and prevents external debris and moisture from entering the maintenance well.

[0015] Furthermore, a voice alarm is installed at the bottom of the inspection well near the cavity opening. This voice alarm is electrically connected to an infrared detector. Once the infrared detector detects an abnormality, such as the manhole cover being illegally opened, the voice alarm can immediately sound an alarm to promptly remind on-site personnel, serving as an immediate warning. Moreover, the placement of the voice alarm near the cavity opening effectively prevents unauthorized personnel from immediately turning off the alarm after opening the manhole cover.

[0016] Furthermore, the support rod is equipped with a protective lock at the inspection well opening to fix the support device. While fixing the infrared detector, the support rod can also prevent the detector from entering the cavity directly through the inspection well after the well cover is opened, thus playing a protective role.

[0019] Figure 3 A cross-sectional view of this utility model;

[0020] Figure 4 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0021] The reference numerals in the accompanying drawings of the instruction manual include: weighing platform 1, cavity 2, load-bearing device 3, inspection well 4, well cover 5, fixing rod 6, ground lock 7, support rod 8, infrared detector 9, protective lock 10, anti-collision post 11, water guide channel 12, and connecting pipe 13.

[0022] Example 1 is basically as shown in the appendix. Figure 1-4 As shown: The vehicle violation prevention device at the highway entrance overload control checkpoint includes a weighing platform 1, which is located in the overload control checkpoint area at the highway entrance. A cavity 2 is tightly installed at the lower end of the weighing platform 1. The weighing device inside the cavity 2 is precisely connected to the weighing platform 1 to form a stable weighing structure. Multiple inspection wells 4 are evenly distributed on both sides of the weighing platform 1, and these inspection wells 4 are interconnected with the cavity 2. The inspection well 4 is equipped with a cross-shaped support rod 8, which is firmly installed on the inner wall of the inspection well 4. The infrared detector 9 is precisely fixed in the middle of the support rod 8, so that the support rod 8 provides stable and balanced support for the infrared detector 9, effectively reducing the positional displacement and shaking of the detector caused by external vibration or interference, ensuring the accuracy and stability of the detection. At the same time, the detector in the middle position can evenly cover all directions of the inspection well cover 4, significantly reducing the detection blind spot and improving the comprehensiveness and reliability of the detection. Furthermore, the support rod 8 is installed at the position of the inspection well opening and is equipped with a protective lock 10 to fix the support device. This not only plays a stable fixing role for the infrared detector 9, but also prevents personnel from directly entering the cavity 2 through the inspection well 4 after the well cover 5 is opened, thus fully exerting the protective function.

[0023] A manhole cover 5 is installed above the maintenance well 4. The manhole cover 5 is limited by a fixing rod 6. The two ends of the fixing rod 6 are firmly fixed to the ground by a sturdy ground lock 7, which greatly increases the difficulty for unauthorized personnel to enter the maintenance well 4, effectively protects the equipment inside the well, and reduces the risk of the equipment being damaged or tampered with.

[0024] An infrared detector 9 is installed at the center of the lower end face of the manhole cover 5, about 1-2 cm away from the manhole cover 5. This position allows the detector to quickly detect changes the moment the manhole cover 5 is opened, enabling a rapid response and effectively preventing unauthorized operations. At the same time, the central position ensures the balance and accuracy of detection of the opening action of the manhole cover 5 in all directions, reducing blind spots. In addition, maintaining a distance of 1-2 cm from the manhole cover 5 can avoid interference from the vibration and deformation of the manhole cover 5 itself, ensuring the stability and accuracy of the detection signal. Moreover, this position is relatively concealed, making it difficult to be discovered and damaged, which significantly increases the safety and service life of the detector.

[0025] Anti-collision posts 11 are arranged at intervals on one side of the inspection well 4. They are symmetrically arranged on the side of the weighing platform 1. This layout can effectively prevent vehicles from accidentally colliding with the weighing platform 1 and the inspection well 4, reducing the risk of equipment damage and ensuring the normal progress of the inspection work. At the same time, it provides clear and definite driving boundaries and guidance for vehicles, enabling vehicles to pass through the weighing area more properly and greatly reducing the possibility of vehicles deviating from the normal driving route.

[0026] Inside the inspection well 4, at the lower end of the manhole cover 5, there is a water guide channel 12 connected by a connecting pipe 13. The water guide channel 12 is arranged in a ring around the inspection well 4. The edge of the manhole cover 5 is exactly located at the center of the width of the water guide channel 12. This structure ensures that the water flowing from the manhole cover 5 falls directly into the water guide channel 12, maximizing the collection of rainwater or other accumulated water and significantly improving drainage efficiency. The edge of the manhole cover 5 is located at the center of the width of the water guide channel 12, which makes the water flowing down from the manhole cover 5 flow into the water guide channel 12 more concentratedly, effectively reducing the possibility of water overflowing from the edge of the water guide channel 12. In addition, it reduces the impact of water flow on the seal between the manhole cover 5 and the well opening, which helps to maintain good sealing performance and successfully prevents external debris and water vapor from entering the interior of the inspection well 4.

[0027] At the bottom of the inspection well 4, near the opening of the cavity 2, there is a voice alarm that is electrically connected to the infrared detector 9. Once the infrared detector 9 detects an abnormality, such as the manhole cover 5 being illegally opened, the voice alarm can immediately emit a loud sound alarm to promptly remind the personnel on site. Moreover, placing the voice alarm near the opening of the cavity 2 effectively prevents unauthorized personnel from turning off the alarm immediately after opening the manhole cover 5, thus playing an immediate warning role.

[0028] When in use, if any unauthorized personnel attempt to open the manhole cover 5, the infrared detector 9 will transmit a signal to the alarm in the duty room or office after detecting the displacement of the manhole cover 5, thus alerting the unauthorized personnel. At the same time, a voice alarm is also installed at the bottom of the inspection well 4 to alert the unauthorized personnel. When it rains, rainwater will flow in along the edge of the manhole cover 5 and be discharged through the water guide channel 12 and the water guide pipe to prevent water from entering the cavity 2.

[0029] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
