[0020] The utility model will be further explained in detail in connection with the drawings and embodiments:
[0021] As Figures 1-2 The utility model discloses a novel expressway special lane buried magnetic induction detector, including detector main body 1, the upper and lower sides of detector main body 1 are provided with limit plate 4, be provided with a plurality of dampers 2 between limit plate 4 and detector main body 1, a plurality of dampers 2 are annular equidistance arrangement with detector main body 1 as the axle, and the both ends of damper 2 are connected with detector main body 1 and limit plate 4 respectively, and a pair of limit plate 4 are parallel with detector main body 1 and set up.
[0022] The expressway special lane buried magnetic induction detector is a traffic detection equipment, is usually installed below the ground of the special lane on the expressway, is used for detecting the passing condition and vehicle flow, and the detector passes through the buried magnetic induction coil to perceive the existence and passing of the vehicle, and then monitors the flow and speed of the vehicle in real time, and the existing detector lacks the shock absorption structure for the detector body, the driving speed of the vehicle on the expressway is fast, and the ground vibration can be caused when the vehicle passes, if the buried magnetic induction detector does not have the shock absorption structure, these vibrations can cause damage to the equipment, influence the normal work of the equipment, and seriously reduce the service life of the detector.
[0023] In the scheme, the user buries detector main body 1 underground, and a plurality of dampers 2 on the upper and lower sides of detector main body 1 can play a shock absorption role on detector main body 1 from the upper and lower directions of detector main body 1, the damper 2 can be set as viscous damper, when subjected to external force, a pair of limit plates 4 first bear the pressure, then conduct to damper 2, and the viscous medium such as oil, liquid in damper 2 can produce damping effect, hinder the movement of object vibration, convert vibration energy into heat energy, thereby reducing the vibration amplitude, and then through the setting of a plurality of dampers 2, the vibration caused by the vehicle passing through the road surface to detector main body 1 can be effectively reduced, and the internal parts of detector main body 1 are protected.
[0024] The outer side of damper 2 is sleeved with spring 3, and the both ends of spring 3 are fixedly connected with detector main body 1 and limit plate 4.
[0025] In the scheme, when detector main body 1 is subjected to vibration, a plurality of dampers 2 will be deformed, and then spring 3 is extruded, through the setting of spring 3, the damper 2 can be quickly reset, and then the shock absorption performance is improved.
[0026] AsFigure 4 As shown, a heat-conducting plate 7 is fixedly connected to the outer end of the detector body 1. The heat-conducting plate 7 is arranged around the detector body 1, and multiple heat dissipation fins 8 arranged in a ring at equal intervals are fixedly connected to the outer end of the heat-conducting plate 7.
[0027] In this scheme, the heat-conducting plate 7 is in contact with the outside of the detector body 1, which can effectively absorb the heat generated when the detector body 1 is working and evenly conduct the heat to multiple heat dissipation fins 8, thereby increasing the heat dissipation area of the detector body 1, improving the overall heat dissipation capacity of the detector body 1, and maintaining its stable operation.
[0028] like Figure 3 As shown, internal baffles 6 are fixedly connected to the upper and lower sides of the outer end of the detector body 1. An external baffle 5 for use with the limiting plate 4 is fixedly connected to one end of a pair of limiting plates 4 close to each other. The inner wall of the external baffle 5 abuts against the outer surface of the limiting plate 4.
[0029] In this design, the outer baffle 5 and the inner baffle 6 can enclose multiple dampers 2 and springs 3, thereby preventing underground soil and gravel from contacting the dampers 2 and springs 3 and causing them to wear or get stuck. When a pair of limiting plates 4 are squeezed, the outer baffle 5 and the inner baffle 6 can move relative to each other, but they will not separate during the movement, thus ensuring the coverage of the dampers 2 and springs 3.
[0030] The limiting plate 4 located on the upper side of the detector body 1 is made of heat insulation material.
[0031] This solution sets the limiting plate 4 located on the upper side of the detector body 1 as a heat insulation material. This is because when the air temperature is high, the road surface temperature is high due to the influence of sunlight. The setting of the limiting plate 4 can play a heat insulation role, reduce the transfer of road surface temperature to the detector body 1, and ensure that the detector body 1 operates within a stable temperature range.
[0032] The specific implementation process is as follows:
[0033] In use, the user buries the detector body 1 under the road surface. When a vehicle passes by, the limiting plate 4 located on the upper side of the detector body 1 first bears the pressure, and then transmits it to the damper 2. The viscous medium in the damper 2, such as oil or liquid, will produce a damping effect, which will hinder the movement of the object's vibration and convert the vibration energy into heat energy, thereby reducing the vibration amplitude. At the same time, the damper 2 and the limiting plate 4 located on the lower side of the detector body 1 will further offset the vibration and play a shock absorption effect on the detector body 1. When multiple dampers 2 deform, the spring 3 will be squeezed. Under the elastic action of the spring 3, the damper 2 can be quickly reset.
[0034] The above only is the embodiment of the present application, and the well-known specific technical solutions and / or common knowledge in the scheme are not described in detail. It should be pointed out that, for those skilled in the art, without departing from the technical solutions of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope claimed in the present application should be subject to the content of its claims, and the specific implementation mode and the like recorded in the specification can be used to explain the content of the claims.
