Description

Technical Field

[0001] This utility model relates to the field of road permeability detection technology, specifically a road permeability detection device. Background Technology

[0002] After road construction is completed, a permeability test is required to determine the amount of water seepage per unit time. However, current road permeability testing equipment has low stability during use and is difficult to place stably on sloping road sections, affecting the test results.

[0003] A search revealed a Chinese patent for a road penetration testing device (publication number: CN217654966U). This patent has a pressure plate connected to the bottom of the second connecting seat, which makes it convenient for users to press the cone head. The cone head is connected to the bottom of the pressure plate, which makes it convenient for the product to be inserted into the ground and improves the stability of the product.

[0004] However, in actual use, a sealing material needs to be filled between the bottom of the testing cylinder and the ground to enhance the sealing and prevent the water from leaking out from the gap and affecting the testing effect. However, due to the unevenness of the ground, the filling material between the bottom of the testing cylinder and the ground may not adhere well. Therefore, those skilled in the art have proposed a road penetration testing device to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a road penetration testing device that solves the problem in the background art where uneven ground can easily cause the filling material between the bottom of the testing cylinder and the ground to not adhere well.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A road penetration testing device, comprising:

[0008] A storage cylinder has a mounting block fixedly connected to its bottom. A connecting pipe is connected to the bottom of the storage cylinder. The lower end of the connecting pipe passes through the mounting block and is connected to a detection cylinder. A valve is provided on the surface of the connecting pipe. Connecting plates are provided on the surfaces of both the connecting pipe and the mounting block. A uniformly distributed bracket is fixedly connected between the two connecting plates. A detachable counterweight is provided on the surface of the mounting block.

[0009] An auxiliary component is disposed on the surface of the detection cylinder, and the auxiliary component is used to enhance the sealing between the detection cylinder and the ground;

[0010] The auxiliary component includes an air pump located on top of the connecting plate below. The air pump has an air intake end connected to an air extraction pipe, and the other end of the air extraction pipe is connected to a detection cylinder. The surface of the detection cylinder is provided with an exhaust component.

[0011] Preferably, the bottom of the detection cylinder is provided with a connecting groove, the inner wall of the connecting groove is provided with a sealing bladder, the outlet end of the air pump is connected to an injection pipe, and the other end of the injection pipe is connected to the sealing bladder.

[0012] Preferably, the exhaust assembly includes an exhaust pipe disposed on the surface of the detection cylinder, one end of the exhaust pipe being connected to the sealing bladder, an installation pipe being threadedly connected to the inner wall of the exhaust pipe, and a rotating block being fixedly connected to the upper end of the installation pipe through the exhaust pipe.

[0013] Preferably, the top of the rotating block has a through hole that communicates with the mounting tube, the inner wall of the mounting tube is fixedly connected to a mounting plate, and the bottom of the mounting plate is fixedly connected to a mounting rod.

[0014] Preferably, a sealing plate is slidably connected to the surface of the mounting rod, the outer side of the sealing plate is in contact with the inner wall of the mounting tube, a spring is fixedly connected to the top of the sealing plate, and the other end of the spring is fixedly connected to the surface of the mounting plate.

[0015] Preferably, the surface of the mounting rod has a through groove located between the sealing plate and the mounting plate.

[0016] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0017] 1. By setting auxiliary components, the bulging sealing bladder can achieve the effect of adaptively filling the gaps at the bottom of the ground detection cylinder, effectively improving the sealing performance. At the same time, in order to prevent the gas inside the detection cylinder from affecting the detection during use, the gas inside the detection cylinder is extracted by an air pump and injected into the inside of the sealing bladder, causing the sealing bladder to bulge and gradually fill the inside of the connecting groove. The further bulging sealing bladder can fit against the ground, increasing the sealing performance between the detection cylinder and the ground, preventing water discharged through the connecting pipe from flowing out from the gap between the detection cylinder and the ground. It effectively utilizes the gas inside the detection cylinder as the filling gas inside the sealing bladder, and the operation is simple.

[0018] 2. By setting up an exhaust assembly, as the air pressure increases, the exhaust pipe can apply pressure to the sealing plate under the action of air pressure. The sealing plate affected by the pressure can squeeze the spring and move up the surface of the mounting rod. When the sealing plate moves to the middle of the through groove, the gas that continues to be injected into the sealing bladder can bypass the sealing plate through the through groove and be discharged through the through hole. This avoids the situation where the air pressure inside the sealing bladder becomes too high and causes damage due to the continuous injection of gas after the sealing bladder is in contact with the ground.

[0024] 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.

[0025] Please see Figures 1-4 A road penetration testing device, comprising:

[0026] Storage cylinder 1, with a mounting block 106 fixedly connected to the bottom of storage cylinder 1, and a connecting pipe 102 connected to the bottom of storage cylinder 1. The lower end of the connecting pipe 102 passes through the mounting block 106 and is connected to a detection cylinder 101. A valve 103 is provided on the surface of the connecting pipe 102. A connecting plate 105 is provided on the surface of both the connecting pipe 102 and the mounting block 106. A uniformly distributed bracket 104 is fixedly connected between the two connecting plates 105. A detachable counterweight 2 is provided on the surface of the mounting block 106.

[0027] Auxiliary component 3 is disposed on the surface of detection cylinder 101 and is used to enhance the sealing between detection cylinder 101 and the ground;

[0028] The auxiliary component 3 includes an air pump 301 located on the top of the lower connecting plate 105. The air pump 301 has an air intake end connected to an air extraction pipe 303. The other end of the air extraction pipe 303 is connected to the detection cylinder 101. The surface of the detection cylinder 101 is provided with an exhaust component 31.

[0029] By setting up the air pump 301, the air inside the detection cylinder 101 can be discharged after the detection cylinder 101 is placed on the ground and in contact with the ground. This avoids the air inside the detection cylinder 101 affecting the accuracy of subsequent detection. The counterweight 2 can increase the counterweight to keep the detection cylinder 101 in close contact with the ground and improve the detection effect.

[0030] Please see Figures 1-4 The bottom of the detection cylinder 101 is provided with a connecting groove 304, and the inner wall of the connecting groove 304 is provided with a sealing bladder 305. The air outlet of the air pump 301 is connected to an injection pipe 302, and the other end of the injection pipe 302 is connected to the sealing bladder 305.

[0031] By setting up a sealing bladder 305, the air pump 301 extracts the gas inside the detection cylinder 101 and injects it into the sealing bladder 305, causing the sealing bladder 305 to bulge and gradually fill the interior of the connecting groove 304. The further bulging of the sealing bladder 305 allows it to conform to the ground, increasing the sealing between the detection cylinder 101 and the ground. This prevents water discharged through the connecting pipe 102 from flowing out from the gap between the detection cylinder 101 and the ground, facilitating the penetration test of the road. This avoids the water leakage caused by the use of sealing materials such as putty for filling in existing equipment, which results in poor adhesion to the bottom surface of the detection cylinder 101. Furthermore, the bulging of the sealing bladder 305 and its conformity to the ground can adapt to different ground flatness, reducing the impact of uneven ground on the test.

[0032] Please see Figures 1-4 The exhaust assembly 31 includes an exhaust pipe 3102 disposed on the surface of the detection cylinder 101. One end of the exhaust pipe 3102 is connected to the sealing bladder 305. The inner wall of the exhaust pipe 3102 is threadedly connected to an installation pipe 3103. The upper end of the installation pipe 3103 passes through the exhaust pipe 3102 and is fixedly connected to a rotating block 3101.

[0033] The top of the rotating block 3101 is provided with a through hole that communicates with the mounting tube 3103. The inner wall of the mounting tube 3103 is fixedly connected to the mounting plate 3106, and the bottom of the mounting plate 3106 is fixedly connected to the mounting rod 3107.

[0034] A sealing plate 3108 is slidably connected to the surface of the mounting rod 3107. The outer side of the sealing plate 3108 is in contact with the inner wall of the mounting tube 3103. A spring 3104 is fixedly connected to the top of the sealing plate 3108. The other end of the spring 3104 is fixedly connected to the surface of the mounting plate 3106.

[0035] The surface of the mounting rod 3107 has a through groove 3105 located between the sealing plate 3108 and the mounting plate 3106.

[0036] During the process of injecting gas from the detection cylinder 101 into the sealing bladder 305 using the air pump 301, the sealing bladder 305, after being pressed against the ground, is blocked by the ground, which increases the air pressure inside the sealing bladder 305. As the air pressure increases, it can exert pressure on the sealing plate 3108 through the exhaust pipe 3102. The sealing plate 3108, affected by the pressure, can squeeze the spring 3104 and move it up the surface of the mounting rod 3107. When the sealing plate 3108 moves to the middle of the through groove 3105, the gas that continues to be injected into the sealing bladder 305 can bypass the sealing plate 3108 through the through groove 3105 and be discharged through the through hole. This avoids the situation where the air pressure inside the sealing bladder 305 becomes too high and causes damage due to the continuous injection of gas after the sealing bladder 305 is pressed against the ground. At the same time, after the test is completed, the gas inside the sealing bladder 305 can be released by disassembling the rotating block 3101 and the exhaust pipe 3102 by thread.

[0037] Working principle: After the detection cylinder 101 is placed on the ground and in contact with it, the air pump 301 and the air extraction pipe 303 are used to expel the air inside the detection cylinder 101, avoiding the impact of the presence of air inside the detection cylinder 101 on the accuracy of subsequent tests. The counterweight 2 increases the weight to keep the detection cylinder 101 in close contact with the ground, improving the test effect. During the air extraction process, as the air pump 301 injects the gas inside the detection cylinder 101 into the sealed bladder 305, the sealing bladder 305, being in close contact with the ground, is blocked by the ground, which increases the air pressure inside the sealed bladder 305. With the increase in air pressure, the air can be expelled through the air pump 301. The air pipe 3102 applies pressure to the sealing plate 3108. Under the influence of the pressure, the sealing plate 3108 can squeeze the spring 3104 and move it up the surface of the mounting rod 3107. When the sealing plate 3108 moves to the middle of the through groove 3105, the gas that continues to be injected into the sealing bladder 305 can bypass the sealing plate 3108 through the through groove 3105 and be discharged through the through hole. This avoids the situation where the internal air pressure of the sealing bladder 305 becomes too high and causes damage due to the continuous injection of gas after the sealing bladder 305 is in contact with the ground. At the same time, after the test is completed, the gas in the sealing bladder 305 can be released by disassembling the rotating block 3101 from the exhaust pipe 3102.
