[0012] 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.

[0013] Example: Figure 1-6 As shown, this utility model provides an engineering level testing instrument, including a base plate 1, on which a testing component 2 is mounted. Two symmetrically distributed drive shafts 3 are rotatably mounted on the lower surface of the base plate 1, and large rollers 4 are fixedly mounted at both ends of the two drive shafts 3. A push rod 5 is fixedly mounted at one end of the upper surface of the base plate 1, and a conical push plate 6 is detachably mounted at one end of the base plate 1 by bolts. The bottom end of the push plate 6 does not contact the ground to prevent wear caused by contact with the ground. The gap between the push plate 6 and the ground will not affect normal testing. Rotary mounting within the base plate 1... The system is equipped with a first rotating shaft 14 and a second rotating shaft 16. A large gear 10 and a second bevel gear 13 are fixedly mounted at the upper and lower ends of the first rotating shaft 14, respectively. A small gear 11 and a fan blade 15 are fixedly mounted at the upper and lower ends of the second rotating shaft 16, respectively. A first bevel gear 12 is fixedly mounted on one of the drive shafts 3, and the first bevel gear 12 meshes with the second bevel gear 13. A fan shroud 7 is fixedly mounted on the lower surface of the base plate 1, and the fan blade 15 is located inside the fan shroud 7. Multiple guide plates 17 are fixedly mounted at the bottom end of the fan shroud 7, with the guide plates 17 facing... The fan cover 7 is tilted on both sides, and the push rod 5, in conjunction with the drive shaft 3 and the large roller 4, can push the base plate 1 to move on the road surface to be inspected. The base plate 1 pushes the push plate 6 to move synchronously. The push plate 6 will push away large particles of foreign matter in the area to be inspected on the road surface and slide them to both sides. Since there is a certain gap between the push plate 6 and the ground, some small particles of foreign matter may be cleaned up by the push plate 6. At the same time as the drive shaft 3 rotates, one of the drive shafts 3 drives the first bevel gear 12 to rotate. The first bevel gear 12 drives the second bevel gear 13 to rotate. The second bevel gear 13 passes through The first rotating shaft 14 drives the large gear 10 to rotate, which in turn drives the small gear 11 to rotate. The small gear 11 then drives the fan blade 15 to rotate via the second rotating shaft 16. Since the large gear 10 drives the small gear 11 to accelerate rotation, the rotational speed of the fan blade 15 is increased, thus increasing the wind force. The wind force generated by the rotation of the fan blade 15 is blown out through the guide plate 17 on the fan cover 7, blowing away the foreign particles in the area to be detected on the road surface to both sides. This removes foreign objects from the area to be detected on the road surface, preventing them from affecting the accuracy of the detection.

[0014] The detection component 2 includes a mounting bracket 201, which is fixedly mounted on the upper surface of the base plate 1. A power supply box 206 is fixedly mounted on the top of the mounting bracket 201. A first sliding plate 204 and a second sliding plate 205, arranged vertically, are slidably mounted inside the mounting bracket 201. A bidirectional lead screw 207 is rotatably mounted inside the mounting bracket 201 and threaded into the first sliding plate 204 and the second sliding plate 205. A plurality of first conductive plates 210, evenly distributed, are fixedly mounted on the lower surface of the first sliding plate 204. A plurality of first indicator lights 208, evenly distributed, are fixedly mounted on one side of the first sliding plate 204. The number and position of the first indicator lights 208 correspond one-to-one with the number and position of the first conductive plates 210. The conductive sheet 210 is connected by a wire. Multiple second conductive sheets 211 are fixedly installed on the upper surface of the second sliding plate 205 at equal intervals. Multiple second indicator lights 209 are fixedly installed on one side of the second sliding plate 205 at equal intervals, and the number and position of the second indicator lights 209 correspond one-to-one with the number of second conductive sheets 211. The second indicator lights 209 are connected to their corresponding second conductive sheets 211 by wires. Multiple metal rods 202 are inserted through the fixing frame 201 at equal intervals, and the metal rods 202 penetrate the bottom plate 1. The number and position of the metal rods 202 correspond one-to-one with the first conductive sheet 210 and the second conductive sheet 211. Small rollers 203 are rotatably installed at the bottom ends of the multiple metal rods 202, and a first roller 203 is fixedly installed at the top ends of the multiple metal rods 202. Three conductive plates 212 are provided, and the third conductive plate 212 can contact the corresponding first conductive plate 210 and second conductive plate 211. The third conductive plate 212 is located in the middle of the corresponding first conductive plate 210 and second conductive plate 211. A storage battery is installed in the power supply box 206. Multiple first conductive plates 210 are connected in series with wires and connected to the positive terminal of the storage battery. Multiple second conductive plates 211 are connected in series with wires and connected to the positive terminal of the storage battery. Multiple third conductive plates 212 are connected in series with wires and connected to the negative terminal of the storage battery. A power switch is installed on the power supply box 206 to control the power supply to be turned on and off. Depending on the detection accuracy, the first sliding plate 204 and the second sliding plate 205 can be moved closer or closer together by the bidirectional lead screw 207. The distance between the first conductive sheet 210, the second conductive sheet 211, and the corresponding third conductive sheet 212 is adjusted by moving them apart. Simultaneously, the base plate 1 moves, pushing the detection component 2 to move synchronously. When there is a depression in the road surface, the small roller 203 at the corresponding position drives the metal rod 202 to descend, which in turn drives the corresponding third conductive sheet 212 to descend. If the depression depth exceeds the normal range, i.e., the levelness is unqualified, the third conductive sheet 212 contacts the corresponding second conductive sheet 211. At this time, the corresponding second indicator light 209 is energized and illuminates red, indicating that the levelness of the depression at this location in this section of the road is unqualified. If the third conductive sheet 212 does not contact the corresponding second conductive sheet 211, the corresponding second indicator light 209 does not illuminate, indicating that the depression is within the normal range.When there is a bump in the road surface, the small roller 203 at the corresponding position drives the metal rod 202 to rise. The metal rod 202 then drives the corresponding third conductive plate 212 to rise. If the bump exceeds the normal range, i.e., the levelness is unqualified, the third conductive plate 212 contacts the corresponding first conductive plate 210. At this time, the corresponding first indicator light 208 is energized and illuminates green, indicating that the levelness of the bump at this location in this road section is unqualified. If the third conductive plate 212 does not contact the corresponding first conductive plate 210, the corresponding first indicator light 208 does not illuminate, indicating that the bump is within the normal range.

[0015] The lower surface of the base plate 1 is detachably mounted with a first protective cover 8 by screws, and the first bevel gear 12 and the second bevel gear 13 are located inside the first protective cover 8. One of the drive shafts 3 is inserted through the first protective cover 8. The upper surface of the base plate 1 is detachably mounted with a second protective cover 9 by screws, and the large gear 10 and the small gear 11 are located inside the second protective cover 9. The first protective cover 8 can prevent foreign objects such as sand and gravel from affecting the meshing transmission of the first bevel gear 12 and the second bevel gear 13 during testing. The second protective cover 9 can prevent foreign objects such as sand and gravel from affecting the meshing transmission of the large gear 10 and the small gear 11 during testing.

[0016] Working Principle: In use, the device is first placed on the surface to be inspected. Depending on the inspection accuracy, the bidirectional lead screw 207 moves the first sliding plate 204 and the second sliding plate 205 closer together or further apart to adjust the distance between the first conductive sheet 210, the second conductive sheet 211, and the corresponding third conductive sheet 212. Then, the power is turned on, and the push rod 5, in conjunction with the drive shaft 3 and the large roller 4, pushes the base plate 1 to move on the surface to be inspected. The base plate 1 pushes the push plate 6 to move synchronously. The push plate 6 pushes away large particles of foreign matter in the area to be inspected and slides them to the sides. Because there is a certain gap between the push plate 6 and the ground, some small particles of foreign matter will not be removed by the push plate 6. Simultaneously, the drive shaft 3 rotates... One of the drive shafts 3 drives the first bevel gear 12 to rotate, the first bevel gear 12 drives the second bevel gear 13 to rotate, the second bevel gear 13 drives the large gear 10 to rotate via the first rotating shaft 14, the large gear 10 drives the small gear 11 to rotate, and the small gear 11 drives the fan blade 15 to rotate via the second rotating shaft 16. Since the large gear 10 drives the small gear 11 to accelerate the rotation, the rotation speed of the fan blade 15 can be increased, thus increasing the wind power. The wind power generated by the rotation of the fan blade 15 is blown out through the guide plate 17 on the fan cover 7, blowing away the small particles and foreign objects in the area to be detected on the road surface to both sides, thereby clearing the small particles and foreign objects in the area to be detected on the road surface and preventing the small particles and foreign objects on the road surface from affecting the accuracy of the detection. As the base plate 1 moves, it pushes the detection component 2 to move synchronously. When there is a depression in the road surface, the small roller 203 at the corresponding position drives the metal rod 202 to descend. The metal rod 202 drives the corresponding third conductive plate 212 to descend. If the depression depth exceeds the normal range, i.e., the levelness is unqualified, the third conductive plate 212 contacts the corresponding second conductive plate 211. At this time, the corresponding second indicator light 209 is energized and illuminates red, indicating that the levelness of the depression at this position in this road section is unqualified. If the third conductive plate 212 does not contact the corresponding second conductive plate 211, the corresponding second indicator light 209 does not illuminate, indicating that the levelness of the depression at this position in this road section is unqualified. This indicates that the depression here is within the normal range. When there is a bump in the road surface, the small roller 203 at the corresponding position drives the metal rod 202 to rise, and the metal rod 202 drives the corresponding third conductive piece 212 to rise. If the bump exceeds the normal range, that is, the levelness is not up to standard, the third conductive piece 212 contacts the corresponding first conductive piece 210. At this time, the corresponding first indicator light 208 is energized and lights up green, indicating that the levelness of the bump at this position in this section of the road is not up to standard. If the third conductive piece 212 does not contact the corresponding first conductive piece 210, the corresponding first indicator light 208 does not light up, indicating that the bump here is within the normal range.
