[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model patent clearer, the technical solutions of the embodiments of this utility model patent will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model patent, not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model patent are within the scope of protection of this utility model patent.

[0029] This application discloses a road icing weather forecast and early warning device.

[0030] Referring to the attached diagram in the instruction manual, the road icing weather forecast and early warning device includes a beam 1, a sleeve 2, an equipment rod 3, and detection equipment. The beam 1 is set and installed at the corresponding observation point. The sleeve 2 is inserted through and fixedly installed on the beam 1. The equipment rod 3 is fixedly installed in the upper end face of the sleeve 2. The detection equipment is installed on the equipment rod 3 and includes a humidity detection device 4 and a temperature detection device 5.

[0031] When humidity detection device 4 and temperature detection device 5 are in operation, the factors contributing to road icing are detected.

[0032] In some embodiments, a communication device and a solar panel 10 are mounted on the upper surface of the device rod 3. A sliding work platform 11 is mounted on the device rod 3, and a drive motor 12 is mounted on the sliding work platform 11. The drive end of the drive motor 12 acts on the sliding operation along the device rod 3. The sliding work platform 11 is slidably connected to the device rod 3 via a guide rail, and the drive motor 12 drives the platform to rise and fall via a gear rack or lead screw and nut mechanism.

[0033] The drive motor 12 abuts against the equipment rod 3, causing the working platform to slide up and down along the equipment rod 3. This enables high-precision detection of temperature and humidity under different height conditions.

[0034] Furthermore, a sampling barrel 13 is fixedly sleeved on the outside of the humidity detection device 4. A motor is installed inside the sampling barrel 13. Both ends of the sampling barrel 13 are sealed, and sampling slits are provided at both ends of the sampling barrel 13. The temperature detection device 5 is installed on the drive end of the torque motor 16. The sampling barrel 13 and the torque motor 16 are fixedly mounted on the work platform. The sampling slits of the sampling barrel 13 are symmetrically distributed, and the fan is used to drive airflow through the slits into the sampling barrel.

[0035] The humidity detection device 4 is optimized to improve the confidence level of the detection samples by using an average sampling method within a certain range; the temperature detection device 5 adopts a scanning sampling method to solve the influence of the heat absorption characteristics of the metal material on the surrounding relative humidity and temperature.

[0036] In some embodiments, assembly holes are provided on the beam plate 1. The thickness of the beam plate 1 is not less than five millimeters, and there are not less than four assembly holes. Fixed rivets 9 are installed in the assembly holes. The length of the rivets 9 is not less than 80 centimeters. Multiple rivets 9 are fixed in the assembly holes in a cross-shaped manner. The rivets 9 are constrained and abutted against the assembly holes. The assembly holes are located at the edge of the sleeve 2 and are arranged in a ring array.

[0037] The constraint and fixing effect between the ground rivet 9 and the assembly hole not only realizes the fixed installation of the device, but also meets the requirements of easy loading and unloading.

[0038] In some embodiments, a drill rod 6 is provided inside the sleeve 2 and the equipment rod 3. A spiral groove is provided on the inner side of the sleeve 2.

[0039] The drill rod 6 includes a drill bit and a drive rod 21 connected to the drill bit. The drive rod 21 has a drive thread on its outer side, and the drive thread engages with the helical groove inside the sleeve 2 for abutment movement.

[0040] A temperature sensing rod 8 is installed inside the drive rod 21. The upper end of the temperature sensing rod 8 is connected to the groove end inside the equipment rod 3 via a hydraulic rod. A temperature measuring probe is installed at the lower end of the temperature sensing rod 8.

[0041] Temperature sensor 8 is a temperature measuring rod.

[0042] When the drill rod 6 generates relative motion through the drive thread and helical groove.

[0043] First, drill rod 6 moves downward to complete the drilling operation at the corresponding point and loosen the soil. Then, the hydraulic rod is activated, causing the temperature sensing rod 8 to move downward and insert into the corresponding layer, thus measuring the temperature within the surface structural layer.

[0044] A groove is provided on the lower end face of the equipment rod 3, and the upper end of the hydraulic rod is fixedly installed in the groove.

[0045] This addresses the issue of the significant interference from ambient (air) temperature when using a rocker-type temperature measuring device to detect surface temperature.

[0046] In some embodiments, the drill bit includes a reference ring 18, a crossbeam 19 fixedly disposed on the reference ring 18, a rack plate 20 mounted on the lower end face of the crossbeam 19, a drive rod 21 including a cylindrical metal cylinder structure, the lower end face of the drive rod 21 being fixedly connected to the reference ring 18, and a discharge window provided in the sleeve 2, the discharge window being spirally distributed.

[0047] Optimize the structural design of the drill bit to improve its adaptability to this device.

[0048] The design of the reference ring 18, crossbeam 19, and cylindrical sleeve 2 facilitates the discharge of loose soil from the borehole. An additional discharge port is added to prevent clogging.

[0049] Furthermore, a threaded drive ring 7 is installed on beam 1.

[0050] The threaded drive ring 7 includes a rotating shaft mounted on the beam plate 1, a drive wheel set on the rotating shaft, and a threaded ring set on the outside of the drive wheel. The threaded ring and the drive thread engage in abutment movement.

[0051] The beam plate 1 is provided with a positioning groove for installing the rotating shaft, and a working window is provided on one side of the sleeve 2. The threaded drive ring 7 passes through the working window and engages with the drive thread to move. The beam plate 1 is provided with a quick-release clip for fixing the threaded drive ring 7.

[0052] The upper end of the shaft is provided with a slot key for connection with the drive device.

[0053] When drilling rod 6 needs to be operated in the air, a drive device can be used to connect with the rotating shaft to realize the drilling operation.

[0054] The quick-release clip fixes the threaded drive ring 7 onto the beam plate 1, and the threaded ring in the threaded drive ring 7 is connected to the drive thread in the drill rod 6.

[0055] When the drive equipment is in operation, it sequentially passes through the threaded drive ring 7 and the drill rod 6 to complete the drilling and resetting operations.

[0056] The loose soil drilled out by drill rod 6 is discharged through the discharge window and the working window.

[0057] In some embodiments, an unfolding support arm 22 is provided on the temperature sensing rod 8, and a temperature measuring probe is installed on the unfolding support arm 22. The unfolding support arm 22 is connected to the temperature sensing rod 8 through a movable shaft. Multiple unfolding support arms 22 are provided, and multiple unfolding support arms 22 are connected to a tension rod 23. One end of the tension rod 23 is fixedly connected to the equipment rod 3.

[0058] The upper end of the tension rod 23 is set at the edge of the groove in the lower end face of the equipment rod 3.

[0059] When the temperature sensing rod 8 moves downward under the drive of the hydraulic rod, the distance between the upper end of the tension rod 23 and the temperature measuring probe increases.

[0060] The extended support arms 22 are arranged in a ring on the temperature sensing rod 8.

[0061] When the hydraulic rod drives the temperature sensing rod 8 to move downward, the tension rod 23 is pulled by the equipment rod 3, causing the unfolding support arm 22 to unfold around the soil layer along the moving axis, forming a ring-shaped temperature measurement area to ensure that the probe is in uniform contact with the soil.

[0062] Under the action of the tension rod 23, the outrigger 22 rotates upward around the movable axis and unfolds; then, the temperature measuring probe installed on the outrigger 22 is inserted into the soil to perform the detection operation. This solves the error of inaccurate detection caused by a single temperature measuring probe due to surrounding stone particles, loose soil voids, etc.

[0063] Multiple deployable arms 22 are deployed synchronously via tension rods 23 to ensure that the temperature probes make uniform contact with the soil and reduce local errors.

[0064] The communication equipment is equipped with a PLC circuit board. The PLC circuit board is connected to the solar panel 10, humidity detection device 4, temperature detection device 5, drive motor 12, fan, torque motor 16, and temperature measurement probe, respectively.

[0065] The PLC circuit board is connected to the humidity detection device 4, the temperature detection device 5, and the temperature sensing rod 8, respectively, to integrate surface and underground temperature and humidity data and generate an icing warning signal.

[0066] When it is necessary to detect underground temperature, the drive device drives the threaded drive ring 7 to rotate through the rotating shaft. The drive thread of the drive rod 21 cooperates with the spiral groove of the sleeve 2, so that the drilling rod 6 drills downward. After drilling is completed, the hydraulic rod pushes the temperature sensing rod 8 down, the tension rod 23 pulls the unfolding arm 22 to unfold, and the temperature measuring probe is inserted into the soil layer to realize multi-point temperature acquisition.

[0067] The humidity detection device 4 collects air samples through the slit of the sampling barrel 13, and the fan accelerates the airflow to improve sampling efficiency; the temperature detection device 5 rotates under the drive of the torque motor 16 to avoid interference of the device's own heat generation on the local temperature.
