[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] like Figure 1-4 As shown, this application discloses a traffic road detection device, including a water tank 1. Universal wheels 2 are installed at the four corners of the bottom of the water tank 1. A push handle 3 is installed at the rear of the upper end of the water tank 1. A mounting frame 6 is installed at the center of the front end of the water tank 1. A threaded rod 7 is installed in the middle of the mounting frame 6. A turntable 8 is installed at the top of the threaded rod 7. A movable block 9 is installed on the outer side of the threaded rod 7 and inside the mounting frame 6. A road surface permeability meter 10 is installed through the upper and lower ends of the movable block 9. The side wall of the road surface permeability meter 10 is near the top... A water pump 5 is connected to a pipe, and the water pump 5 is connected to a water tank 1 through a pipe. A sealing component is installed on the outer side of the bottom end of the road surface permeability meter 10. The sealing component includes a first mounting ring 11, a second mounting ring 16 is installed in the middle of the bottom end of the first mounting ring 11, a third mounting ring 17 is installed on the outer side of the second mounting ring 16, an inverted trapezoidal mounting groove is opened on the inner side of the third mounting ring 17, a film 18 is installed on the inner side of the mounting groove, and a squeezing component is installed at the bottom end of the first mounting ring 11 and in the mounting groove.

[0020] The water pump 5 sends water from the water tank 1 into the road surface permeability meter 10, reducing the need for manual water injection. The turntable 8 drives the threaded rod 7 to rotate, and the threaded rod 7 drives the road surface permeability meter 10 to descend and contact the ground via the moving block 9. The sealing component on the road surface permeability meter 10 seals the contact point with the ground.

[0021] like Figure 1-4 As shown, the extrusion assembly includes a fourth mounting ring 20. An annular shell 21 is installed at the bottom of the fourth mounting ring 20. Several extrusion rods 23 are installed through the bottom of the annular shell 21. A limit block 22 is installed at the top of the extrusion rod 23. A spring 24 is installed at the upper end of the limit block 22. Several annularly arranged mounting rods 25 are installed at the upper end of the fourth mounting ring 20 and inserted into the first mounting ring 11. The spring 24 extrudes the limit block 22 and the extrusion rods 23 and moves them downward. The extrusion rods 23 drive the film 18 to make tight contact with the ground, thereby improving the sealing performance.

[0022] like Figure 1-3As shown, the first mounting ring 11 has a mounting hole 15 corresponding to the middle of the film 18. A first tube 12 is installed in the mounting hole 15. A second tube 13 is installed on the side of the first tube 12. An air valve 14 is installed on the second tube 13. The first tube 12 is connected to an air pump 4 through a pipe. The air pump 4, in conjunction with the first tube 12, can inject air into the film 18 to expand it. After expansion, the film 18 is tightly attached to the ground, improving the sealing performance. By opening the air valve 14, air can be vented through the second tube 13.

[0023] like Figure 3-4 As shown, magnets 26 are respectively installed at the upper end of the mounting rod 25 and the upper end of the mounting hole at the bottom of the first mounting ring 11. By setting the magnets 26, the extrusion assembly can be installed and fixed.

[0024] like Figure 3-4 As shown, a rubber ring 19 is installed on the outer side of the bottom end of the third mounting ring 17. The bottom end of the rubber ring 19 has an annular groove. By installing the rubber ring 19 with the annular groove, the sealing between it and the ground can be further improved. When the rubber ring 19 contacts the ground, the annular groove can facilitate the deformation of the rubber ring 19 after contact with the ground.

[0025] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] The implementation principle of a traffic road detection device according to an embodiment of this application is as follows:

[0028] In use, the device is moved to the detection point using the push handle 3 and the universal wheel 2. Rotating the turntable 8 drives the threaded rod 7, which is fixed to it, to rotate. Since the threaded rod 7 is rotatably connected to the mounting bracket 6 and threadedly connected to the moving block 9, the rotational motion is converted into linear motion of the moving block 9. The moving block 9 drives the road surface permeability meter 10, which is fixed to it, to descend vertically until its bottom sealing component contacts the road surface. When the permeability meter 10 descends, the rubber ring 19 at the bottom of the sealing component contacts the road surface first. Its annular groove design at the bottom helps to deform upon contact, filling microscopic unevenness and forming the first seal. At the moment of contact, the spring 24 of the compression component is compressed, pushing the limit block 22 and the compression rod 23 downwards. The compression rod 23 acts on the rubber sheet 18 inside the annular shell 21, forcing it to deform downwards and adhere tightly to the road surface. To form the second mechanical seal, the air pump 4 is started, and compressed air acts on the film 18 through the first pipe 12. The film 18 further expands and deforms, tightly adhering to the road surface, significantly enhancing the sealing effect. The air valve 14 is used to control the exhaust of the second pipe 13. During the test, the water pump 5 is started, and the water pump 5 draws water from the water tank 1 through the pipeline and injects it into the cylinder of the road permeability meter 10. The operator observes and records the time required for the water level in the cylinder to drop to a certain height according to the standard test method, and calculates the permeability coefficient of the road surface. After the test, the air valve 14 is opened, and the gas above the film 18 is discharged through the second pipe 13, causing it to contract and reset. The turntable 8 is rotated in the opposite direction, driving the threaded rod 7 to rotate, which drives the moving block 9 and the permeability meter 10 to rise as a whole, detaching from the road surface. The equipment is then moved to the next test point by the pusher 3 and the universal wheel 2.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
