Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 - 10 , the present invention provides a technical solution: a high-temperature wading depth sampling device for a bus, including a sampling mechanism 2 and a vehicle body 1. The sampling mechanism 2 includes an installation box 21, a pressure-type water depth sensor 22 and a temperature sensor 23 installed on the bottom surface of the installation box 21. An installation groove 11 is provided on the bottom surface of the vehicle body 1. The installation box 21 is slidably inserted into the installation groove 11. And the sampling mechanism 2 further includes a microcontroller 26 installed on the rear side surface of the installation box 21. It further includes:

[0032] The limit component 27 is arranged inside the installation box 21 and is used to limit the installation box 21. The limit component 27 includes a rotating rod 271 rotatably connected to the inner bottom surface of the installation box 21, a driving bevel gear 272 coaxially fixed on the circumferential outer wall of the rotating rod 271 and located inside the installation box 21, two fixed rods 273 fixed on the inner bottom surface of the installation box 21 and located on the left and right sides of the rotating rod 271 respectively, two rotating rollers 274 rotatably connected to the same-side fixed rod 273, two driven bevel gears 275 coaxially fixed on the circumferential outer wall of the same-side rotating roller 274 and vertically meshing with the driving bevel gear 272, and a motor 2711 installed on the bottom surface of the installation box 21 and with an output shaft coaxially connected to the rotating rod 271. A rotating cylinder 276 with an internal thread on its inner wall is coaxially fixed on the surface of the rotating roller 274 away from the rotating rod 271. The limit component 27 further includes two screw rods 277 threadedly connected to the same-side rotating cylinder 276, two moving columns 278 coaxially fixed on the surface of the same-side screw rod 277 away from the rotating rod 271, and two guide rods 2713 fixed on the circumferential outer wall of the same-side moving column 278 and slidably connected to the rear inner wall of the installation box 21. And a limit column 279 coaxially fixed on the surface of the moving column 278 away from the rotating rod 271 and slidably inserted into the vehicle body 1. By the combined use of the installation box 21, the pressure water depth sensor 22, the temperature sensor 23 and the microcontroller 26, the wading depth and water temperature of the bus body 1 can be sampled and detected. Through the design of the limit component 27, it is convenient to install the whole sampling mechanism 2 on the vehicle body 1, and at the same time, it is also convenient to disassemble the whole sampling mechanism 2, avoiding the difficult disassembly situation due to rust caused by the fixing method with screws or bolts.

[0033] In this embodiment, limiting holes are provided on the left and right side surfaces of the installation groove 11, and through holes corresponding to the positions and having suitable dimensions of the same-side limiting holes on the outer wall of the installation groove 11 are provided on the left and right side surfaces of the installation box 21. The limit column 279 passes through the same-side through hole on the outer wall of the installation box 21 and is slidably inserted into the same-side limiting hole on the outer wall of the installation groove 11, so that the installation box 21 can be smoothly limited.

[0034] In addition, the sampling mechanism 2 further includes a waterproof control button 25 installed on the bottom surface of the installation box 21 and a wireless charging battery 28 installed on the inner top surface of the installation box 21. And the test end of the pressure water depth sensor 22 is on the same plane as the bottom surface of the vehicle body 1, which can control the motor 2711 and supply power to the motor 2711, and at the same time, can also smoothly detect the wading depth of the bus body 1.

[0035] Further, a guiding groove is provided on the inner wall at the rear side of the mounting box 21, and a guiding block 2710 slidably connected to the guiding groove on the inner wall at the rear side of the mounting box 21 is fixed on the rear surface of the guiding rod 2713, which can guide the movement of the two guiding rods 2713, and thus indirectly guide the movement of the two limiting posts 279.

[0036] Specifically, the limiting assembly 27 further includes a protection box 2712 fixed on the top surface of the mounting box 21, and the motor 2711 is located inside the protection box 2712, which can protect the motor 2711 and thus extend the service life of the motor 2711.

[0037] It should be noted that the sampling mechanism 2 further includes two symmetrically arranged handles 24 fixed on the bottom surface of the mounting box 21, and the shape of the handle 24 is U-shaped, which facilitates the picking up and placing of the mounting box 21 and also facilitates the pushing and pulling of the mounting box 21.

[0038] It should be noted that a sealing ring is provided at the contact part between the rotating rod 271 and the mounting box 21, and a sealing ring is also provided at the position where the limiting post 279 contacts the through hole on the same side of the outer wall of the mounting box 21, which can make the sealing performance of the whole sampling mechanism 2 better and prevent water from entering the mounting box 21.

[0039] It should be emphasized that the longitudinal sectional shape of the guiding groove on the inner wall at the rear side of the mounting box 21 is convex, and the shape of the guiding block 2710 is convex and adapted to the shape of the guiding groove on the inner wall at the rear side of the mounting box 21, which can make the connection between the guiding block 2710 and the guiding groove on the inner wall at the rear side of the mounting box 21 tighter, and thus indirectly make the two limiting posts 279 more stable during the movement process.

[0040] Finally, it should be noted that components such as the vehicle body 1, the pressure water depth sensor 22, the temperature sensor 23, the waterproof control button 25, the microcontroller 26, the motor 2711, and the wireless charging battery 28 involved in the present utility model are all general standard components or components known to those skilled in the art. Their structures and principles can all be known by those skilled in the art through technical manuals or obtained through conventional experimental methods. In the idle space of the present device, all the above electrical components, which refer to power components, electrical components, and the adapted controllers and power supplies, are connected by wires. The specific connection means should refer to the working principle of the present utility model, and the electrical components are electrically connected in accordance with the sequential working order. The detailed connection means are all well-known techniques in the art.

[0041] During the specific use of this embodiment, when the bus body 1 wades through water, the pressure-type water depth sensor 22 transmits a pressure signal to the microcontroller 26, and the temperature sensor 23 transmits a temperature signal to the microcontroller 26. The microcontroller 26 receives the signals and processes the pressure signal according to a pre-determined temperature compensation algorithm to correct the output of the pressure-type water depth sensor 22, so as to eliminate the influence of temperature on pressure measurement. The microcontroller 26 transmits the processed pressure signal and temperature signal to a computer preset in the bus. The computer converts the pressure signal into depth data and transmits the temperature signal to temperature data, thereby enabling the detection of the wading depth and temperature.

[0042] When it is necessary to disassemble the sampling mechanism 2, first rotate the waterproof control button 25 clockwise. The waterproof control button 25 transmits a signal to the microcontroller 26. The microcontroller 26 receives the signal and controls the output shaft of the motor 2711 to rotate. The rotation of the output shaft of the motor 2711 drives the rotating rod 271 coaxially connected thereto to rotate. The rotation of the rotating rod 271 drives the driving bevel gear 272 coaxially fixed thereto to rotate. The rotation of the driving bevel gear 272 drives the two driven bevel gears 275 vertically meshed therewith to rotate. The rotation of the driven bevel gears 275 drives the same-side rollers 274 coaxially fixed thereto to rotate. The rotation of the rollers 274 drives the same-side cylinders 276 coaxially fixed thereto to rotate. The rotation of the cylinders 276 drives the screw 277 connected thereto by threads to move. The screw 277 translates in the direction of the rotating rod 271 under the guiding action of the same-side moving column 278, the same-side guiding rod 2713, the same-side guiding block 2710 and the guiding groove on the rear inner wall of the mounting box 21. The movement of the screw 277 drives the moving column 278 coaxially fixed thereto to move. The movement of the moving column 278 drives the limiting column 279 coaxially fixed thereto to move towards the rotating rod 271. When both limiting columns 279 are located inside the mounting box 21, the motor 2711 is turned off through the waterproof control button 25. Then, the mounting box 21 is pulled by the two handles 24 until the mounting box 21 is separated from the mounting groove 11, thus completing the disassembly work of the entire sampling mechanism 2; conversely, the sampling mechanism 2 can be installed.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
