The structure of the pavement permeameter includes a base, a thick cylinder, and a thin circular tube, usually made of plexiglass, which is convenient to carry and operate.

[0003] According to a road and bridge water seepage detection device provided by Chinese Patent No. CN117491252A, this document includes a counterweight measurement base and a measurement support. The measurement support and the counterweight measurement base are detachably connected by a bolt assembly. A measuring cylinder is fixedly connected to the middle of the measurement support. A chute is provided on the inner side wall of the measuring cylinder, and a recording component is slidably connected to the inner side wall of the chute. A display component is also fixedly connected to the outer wall of the measuring cylinder along the length direction. The recording component can slide up and down in the measuring cylinder to record the water level difference before and after the experiment.

[0031] The dust cleaning device 1 includes a bottom plate 8, a dust collection shell 9, an air pump 10, and a dust suction port 12. Both the bottom plate 8 and the dust collection shell 9 are arranged in a ring shape, and the inner diameters of the bottom plate 8 and the dust collection shell 9 are the same as the diameter of the weight measurement base 2. The dust collection shell 9 is fixedly connected to the top of the bottom plate 8, so that a dust storage space is formed between the bottom plate 8 and the dust collection shell 9. A dust suction port 12 is opened at the inner bottom of the dust collection shell 9, and an air pump 10 is fixedly connected to the dust collection shell 9. When the air pump 10 is turned on, the air pump 10 sucks air into the dust storage space, so that the dust suction port 12 generates suction force, and the dust on the ground surface in the central circular hole of the bottom plate 8 is sucked into the dust storage space, improving the sealing performance between the weight measurement base 2 and the ground.

[0032] Through the setting of the dust cleaning device 1, the air pump 10 sucks air into the dust storage space, so that the dust suction port 12 generates suction force, and the dust on the ground surface in the central circular hole of the bottom plate 8 is sucked into the dust storage space, improving the sealing performance between the weight measurement base 2 and the ground. Thus, it is not necessary to manually clean the measured part of the ground, which is not only more simple and fast in operation, but also the overall structure is light and small, convenient for outdoor measurement use, and has good use effect.

[0033] The dust suction port 12 is arranged in multiple numbers, and the multiple dust suction ports 12 are evenly arranged on the dust collection shell 9.

[0034] The height of the dust collection shell 9 is greater than the height of the weight measurement base 2. Two air pumps 10 are arranged, and the two air pumps 10 are symmetrically arranged on both sides of the top of the dust collection shell 9.

[0035] A sealing structure for improving the sealing performance is provided on the counterweight measurement base 2. The sealing structure includes an annular airbag 14, a sealing layer 20, a mounting groove 15, an inflation channel 19, a guiding block 16, a guiding groove 11, a first inflation port 17, and a second inflation port 13. An annular mounting groove 15 is formed on the counterweight measurement base 2, and the annular airbag 14 is fixedly connected inside the mounting groove. The outer part of the annular airbag 14 is fixedly connected with the sealing layer 20. When the annular airbag 14 is inflated, the annular airbag 14 expands and contacts the ground to improve the sealing effect. A guiding block 16 is fixedly connected to the side surface of the counterweight measurement base 2, and a first inflation port 17 is formed on the guiding block 16. An inflation channel 19 is formed inside the counterweight measurement base 2. One end of the inflation channel 19 communicates with the inside of the annular airbag 14, and the other end of the inflation channel 19 communicates with the first inflation port 17. A vertical guiding groove 11 matching the guiding block 16 is provided on the dust collection housing 9, and a second inflation port 13 is formed on the dust collection housing 9 and located on the guiding groove 11. When the guiding block 16 moves along the guiding groove 11 to the bottom, the second inflation port 13 corresponds to the first inflation port 17. During use, after aligning the guiding block 16 of the counterweight measurement base 2 with the guiding groove 11 and placing it in, under the action of gravity, the counterweight measurement base 2 moves to fit with the ground. At this time, the first inflation port 17 corresponds to the second inflation port 13, and at the same time, the counterweight measurement base 2 completely blocks the dust suction port 12 at the bottom of the dust collection housing 9. The air pump 10 is turned on, and the air pump 10 continuously inflates the dust collection housing 9, so that the gas enters the annular airbag 14 through the second inflation port 13, the first inflation port 17, and the inflation channel 19. The annular airbag 14 expands and fits completely with the ground, improving the sealing performance.

[0036] Through the setting of the sealing structure, during use, after aligning the guiding block 16 of the counterweight measurement base 2 with the guiding groove 11 and placing it in, under the action of gravity, the counterweight measurement base 2 moves to fit with the ground. At this time, the first inflation port 17 corresponds to the second inflation port 13, and at the same time, the counterweight measurement base 2 completely blocks the dust suction port 12 at the bottom of the dust collection housing 9. The air pump 10 is turned on, and the air pump 10 continuously inflates the dust collection housing 9, so that the gas enters the annular airbag 14 through the second inflation port 13, the first inflation port 17, and the inflation channel 19. The annular airbag 14 expands and fits completely with the ground, improving the sealing performance. Thus, the air pump 10 on the dust cleaning device 1 sucks and blows air to achieve dust cleaning of the ground and inflation and sealing of the annular airbag 14.

[0037] A sealing gasket is fixedly connected to the outer side surface of the guiding block 16.

[0038] A filter mesh plate 18 is fixedly connected inside the dust collection housing 9. The filter mesh plate 18 is arranged between the dust suction port 12 and the second inflation port 13, so that dust will not be blown into the annular airbag 14 along with the air flow.

[0039] An anti-slip pad is fixedly connected to the bottom of the bottom plate 8.

[0040] Working principle: Through the setting of the dust cleaning device 1, the air pump 10 sucks air into the dust storage space, causing suction at the dust suction port 12, sucking the dust on the ground surface in the central circular hole of the bottom plate 8 into the dust storage space, improving the sealing performance between the weight measurement base 2 and the ground, so that it is not necessary to manually clean the measured part of the ground. It is not only more simple and fast to operate, but also the overall structure is light and compact, facilitating outdoor measurement use, and has good use effects.
