Description

Technical Field

[0001] The utility model specifically relates to a device for detecting rain and snow conditions on a traffic road surface, and belongs to the technical field of road weather detection. Background Art

[0002] A rain and snow sensor is a qualitative measuring device that can measure whether it is raining or snowing outdoors or in nature. It is usually used in meteorology, transportation, urban construction and other fields to improve the accuracy of weather forecasts, traffic safety and the scientific nature of urban construction. The working principle of a rain and snow sensor mainly relies on optical or electrical principles. In the field of meteorology, it usually works on the optical principle and detects raindrops or snowflakes through a pair of photodiodes (transmitters and receivers). When these precipitation particles pass through the light beam, they scatter part of the light, causing the light intensity received by the receiver to change, thereby judging the presence and intensity of rain and snow. In general, rain and snow sensors play an important role in modern society and are of great significance to improving the quality of production and life and protecting people's lives and property.

[0003] Rain and snow sensors can also detect hail. When hail falls, the sensing element will detect these larger and harder precipitation particles and identify them as hail through the signal processing system. However, in hail weather, the impact force of the falling hail is strong, which will have a certain impact on the rain and snow sensors, resulting in inaccurate measurement or damage to the sensor. In order to reduce the impact of hail on rain and snow sensors, a traffic road pavement rain and snow status detection device is specially proposed. Utility Model Content

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a traffic road pavement rain and snow state detection device comprises a connecting base plate with mounting holes at four corners and a road rain and snow sensor body, the road rain and snow sensor body is mounted on the top of the connecting base plate by connecting bolts, both sides of the top of the connecting base plate are provided with limiting slide grooves, a sliding block is slidably connected in the limiting slide groove, an L-shaped large hail shielding plate is fixedly mounted on the top of the sliding block, a linkage hail removing component is arranged on the outer side wall of the L-shaped large hail shielding plate, a lateral driving component for driving the sliding block to move is fixedly connected to the top of the connecting base plate, a mounting pole is fixed on the top of the connecting base plate, and a camera is fixed on the top of the mounting pole.

[0006] Furthermore, in order to enable the fixed bracket to move synchronously when the L-shaped large hail shield plate moves, the linkage hail removal assembly includes a fixed bracket fixedly installed on the outer side wall of the L-shaped large hail shield plate, and a reinforcing rod is connected to the inner side wall of the fixed bracket.

[0007] Furthermore, in order to protect the cleaning motor through the protective shell, a protective shell is fixed on one end of the fixed bracket, a cleaning motor is fixedly installed on the inner wall of the protective shell, and a hail cleaning plate is connected to the output of the cleaning motor.

[0008] Furthermore, in order to connect and fix the rectangular plate through the support seat, the lateral drive assembly includes a support seat connected to both sides of the top of the connecting base plate by installing bolts, and a rectangular plate with a groove on the bottom is installed on the outer side wall of the support seat.

[0009] Furthermore, in order to drive the screw rod to rotate by the driving motor, a driving motor is fixedly mounted on the inner side wall of the groove on the bottom surface of the rectangular plate, and a screw rod is fixed on the output shaft of the driving motor.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 6As shown, a traffic road pavement rain and snow state detection device comprises a connecting base plate 1 with mounting holes at four corners and a road rain and snow sensor body 2. The road rain and snow sensor body 2 is mounted on the top of the connecting base plate 1 by connecting bolts. Limiting slide grooves are arranged on both sides of the top of the connecting base plate 1. A sliding block 3 is slidably engaged in the limiting slide groove. An L-shaped large hail shielding plate 4 is fixedly installed on the top of the sliding block 3. After the L-shaped large hail shielding plate 4 is driven, the sliding block 3 can slide in the limiting slide groove. A linkage hail removing component 5 is arranged on the outer side wall of the L-shaped large hail shielding plate 4. A lateral driving component 6 for driving the sliding block 3 to move is fixedly connected to the top of the connecting base plate 1. A mounting pole 7 is fixed on the top of the connecting base plate 1. A camera 8 is fixed on the top of the mounting pole 7.

[0024] The linkage hail removal component 5 includes a fixed bracket 501 fixedly installed on the outer side wall of the L-shaped large hail shielding plate 4, a reinforcing rod 502 is connected to the inner side wall of the fixed bracket 501, a protective shell 503 is fixed to one end of the fixed bracket 501, a cleaning motor 504 is fixedly installed on the inner side wall of the protective shell 503, a hail cleaning plate 505 is connected to the output of the cleaning motor 504, the protective shell 503 can protect the cleaning motor 504, and the cleaning motor 504 can drive the hail cleaning plate 505 to rotate after working, and the rotating hail cleaning plate 505 can clean the large hail on the top of the L-shaped large hail shielding plate 4.

[0025] The lateral drive assembly 6 includes a support seat 601 connected to both sides of the top of the connecting base plate 1 by installing bolts, a rectangular plate 602 with a groove on the bottom is installed on the outer wall of the support seat 601, and a driving motor 603 is fixedly installed on the inner wall of the groove on the bottom surface of the rectangular plate 602. A screw rod 604 is fixed on the output shaft of the driving motor 603, and L-shaped driving blocks 605 are threadedly connected to both ends of the screw rod 604, and the L-shaped driving block 605 is located in the groove on the bottom surface of the rectangular plate 602. The L-shaped large hail shielding plate 4 is fixedly connected to one end of the L-shaped driving block 605. The driving motor 603 can drive the screw rod 604 to rotate, and the two L-shaped large hail shielding plates 4 can be close to each other. When one end of the two L-shaped large hail shielding plates 4 is not moved to fit together, a gap can be generated at one end of the two L-shaped large hail shielding plates 4, and this gap is convenient for small hail to pass through.

[0026] A top protective plate 9 is fixed on the outer wall of the mounting pole 7 by means of a fixing screw, and the top protective plate 9 can protect the camera 8. In addition, the driving motor 603 and the cleaning motor 504 can also be remotely controlled. Therefore, when the driving motor 603 is working by remote control, the moving distance of the two L-shaped large hail shielding plates 4 can be observed through the camera 8.

[0027] When the utility model is in use, the user can first install the connecting base plate 1 through the mounting hole on the connecting base plate 1. After the connecting base plate 1 is installed, the utility model can also be installed and fixed. At this time, the road rain and snow sensor body 2 can detect rain and snow. When the road rain and snow sensor body 2 works in hail weather, since the impact force generated by large hail and small hail is different in hail weather, in order to reduce the damage caused by large hail to the road rain and snow sensor body 2, the user can make the driving motor 603 work and drive the screw rod 604 to rotate in place. At this time, the two L-shaped driving blocks 605 on the screw rod 604 can be displaced and approach each other, so as to drive the two L-shaped large hail to move. The hail shielding plates 4 move and approach until one end of the two L-shaped large hail shielding plates 4 maintains a certain distance. After the two L-shaped large hail shielding plates 4 move, small hail can fall onto the road rain and snow sensor body 2 through the gap at one end of the two L-shaped large hail shielding plates 4, so that the road rain and snow sensor body 2 can normally detect hail weather, and the large hail can be blocked by the L-shaped large hail shielding plates 4, thereby increasing the service life of the road rain and snow sensor body 2. When the cleaning motor 504 works, it can drive the hail cleaning plate 505 to rotate, and the hail cleaning plate 505 can remove the large hail remaining on the L-shaped large hail shielding plates 4, thereby preventing the large hail from remaining on the L-shaped large hail shielding plates 4.
