Description

Technical Field

[0001] This utility model belongs to the field of road quality testing, specifically relating to sealing components and road seepage detection equipment. Background Technology

[0002] Road surface permeability testing refers to determining the permeability of asphalt mixture pavements. Existing road surface permeability testing equipment measures the amount of water that seeps into a certain area of ​​the pavement per unit time. During the testing process, it is crucial to ensure a tight seal between the equipment base and the road surface; otherwise, water will simply flow across the surface instead of seeping into it. To address this, current technologies typically rely on the weight of the equipment to press it firmly onto the pavement or on applying sealant. However, relying solely on weight is insufficient to guarantee a proper seal, while applying sealant is cumbersome.

[0003] To address this, existing technologies have proposed installing vacuum suction cups on the base of the seepage device. By evacuating the air, the vacuum suction cups adhere tightly to the road surface, and the material of the suction cups (such as flexible rubber) also acts as a sealing ring, effectively achieving a seal. Patents CN201910268821.6 and CN202023258749.6 disclose this sealing method. However, this sealing method still has some technical problems: when the road surface is uneven, the suction cups have difficulty achieving the desired adhesion effect, which also affects the sealing performance. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a sealing component and a road surface seepage detection device to solve the problem that when the road surface is uneven, the suction cup is difficult to achieve the ideal adsorption effect, which also affects the sealing effect.

[0005] According to the embodiments of this utility model, the following technical solution is adopted:

[0006] The sealing component includes a mounting ring, an inner sealing assembly disposed inside the mounting ring, an outer sealing assembly disposed outside the mounting ring, and a filling assembly disposed between the inner and outer sealing assemblies. The inner sealing assembly includes a sealing ring connected to the mounting ring and a suction device for drawing air from the sealing ring. The sealing ring has an n-shaped or inverted V-shaped cross-section. The outer sealing assembly includes an annular sealing ring and several pressure rods disposed circumferentially along the sealing ring. The pressure rods are slidably connected to the mounting ring vertically or are telescopic structures. An inner pressure ring and an outer pressure ring are mounted on the mounting ring. The inner pressure ring is used to press the outer side of the sealing ring, and the outer pressure ring is used to press the inner side of the sealing ring. A filling space is formed between the inner and outer pressure rings, and the filling assembly is used to fill the filling space with a medium.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] In this solution, the inner sealing component draws air from the sealing ring, causing it to adhere to the road surface to achieve a seal. The outer sealing component presses the sealing ring onto the road surface using pressure rods to achieve a seal. Even if the road surface is uneven, the sliding or extending stroke of each pressure rod can be adjusted according to the road conditions through the sliding or extending of multiple pressure rods, so as to make the sealing ring and the road surface fit as closely as possible.

[0009] By setting up inner and outer sealing components, a double seal is achieved. Even if water flows through the inner sealing component, it will be blocked by the sealing of the outer sealing component, reducing the flow of water on the road surface.

[0010] In addition, the inner and outer pressure rings can also suppress the sealing rings and seals, thereby improving the sealing effect. Furthermore, by using a filling assembly, once the filling space is filled with the medium, the amount of water flowing out through the filling space from the outer sealing assembly can be further reduced.

[0011] Furthermore, both the inner pressure ring and the outer pressure ring include a fixed part and a sliding part that is slidably connected to the fixed part, and a spring is connected between the sliding part and the fixed part.

[0012] Furthermore, the filling assembly includes a filling air pump for inflating the filling space.

[0013] Furthermore, a rubber ring is fixed to the outside of the sealing ring, and the upper surface of the rubber ring is provided with several annular protrusions. The cross-section of the protrusions is inverted V-shaped, and an annular groove is formed between adjacent protrusions.

[0014] Furthermore, a guide surface is provided on the outer side of the rubber ring, and the outer side of the guide surface is inclined downward.

[0015] Furthermore, a pressure sensor for detecting the air pressure inside the filling space is installed on the mounting ring.

[0016] Furthermore, the filling assembly includes a dispensing pump for dispensing adhesive into the filling space.

[0017] Furthermore, both the inner and outer pressure rings can be detachably connected to the mounting ring.

[0018] According to the embodiments of this utility model, the following technical solution is adopted:

[0019] The road surface seepage detection equipment includes a bracket, a measuring cylinder mounted on the bracket, and a sealing component. The mounting ring is detachably connected to the bracket, and the inner side of the mounting ring is for the measuring cylinder to pass through.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In this solution, a sealing component is used to achieve a seal, which allows the water discharged from the measuring cylinder to be sealed inside the sealing component, reducing the flow of water on the road surface and improving the accuracy of the detection.

[0022] Furthermore, the bracket includes a mounting plate and support legs mounted on the lower end of the mounting plate, with a mounting ring connected to the lower side of the mounting plate. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings, and specific embodiments will be given.

[0027] like Figure 1 , Figure 2 As shown, the sealing component includes a mounting ring 4, an inner sealing assembly disposed inside the mounting ring 4, an outer sealing assembly disposed outside the mounting ring 4, and a filling assembly disposed between the inner sealing assembly and the outer sealing assembly.

[0028] The inner sealing assembly includes a sealing ring 6 and a suction device for drawing air from the sealing ring 6. A connecting rod 12 connects the sealing ring 6 and the mounting ring 4. Specifically, the connecting rod 12 is vertically slidably connected to the mounting ring 4, or the connecting rod 12 is a telescopic structure. In this embodiment, the connecting rod 12 is an existing electric telescopic rod, with one end fixed to the mounting ring 4 and the other end fixed to the sealing ring 6. The suction device is a suction air pump 8, and an air pipe 7 connects the suction air pump 8 and the sealing ring 6. After the sealing ring 6 contacts the road surface through the extension and retraction of the connecting rod 12, the air pump 8 draws out the gas from the sealing ring 6, causing the sealing ring 6 to adhere to the road surface. In actual design, the sealing ring 6 has an n-shaped or inverted V-shaped cross-section, thus forming a cavity inside the sealing ring 6, similar to a suction cup structure, which makes it easier to adhere to the road surface. This design also increases the contact area between the sealing ring 6 and the road surface when the sealing ring 6 is adhered to the road surface, achieving a better sealing effect.

[0029] The external sealing assembly includes an annular sealing ring 10 and several pressure rods 11 arranged circumferentially along the sealing ring 10. The pressure rods 11 are slidably connected to the mounting ring 4 vertically, or the pressure rods 11 are telescopic structures. In this embodiment, the pressure rods 11 are electric telescopic rods in the prior art. One end of the pressure rod 11 is fixed to the mounting ring 4, and the other end of the pressure rod 11 is fixed to the sealing ring 10. By extending and retracting the pressure rods 11, the sealing ring 10 can be pressed onto the road surface. Even if the road surface is uneven, the extension and retraction stroke of each pressure rod 11 can be adjusted according to the road surface conditions to make the sealing ring 10 fit the road surface as completely as possible.

[0030] An inner pressure ring 20 and an outer pressure ring 17 are installed on the mounting ring 4. The inner pressure ring 20 is used to press the outer side of the sealing ring 6, and the outer pressure ring 17 is used to press the inner side of the sealing ring 10. Through the pressing of the inner pressure ring 20 and the outer pressure ring 17, the adhesion between the sealing ring 6, the sealing ring 10 and the road surface is improved to a certain extent. A filling space is formed between the inner pressure ring 20 and the outer pressure ring 17. A filling assembly is used to fill the filling space with a medium. In this embodiment, the filling assembly includes a filling air pump for inflating the filling space. The mounting ring 4 has a channel 5 for gas to enter the filling space.

[0031] In practical use, the extension and retraction of the connecting rod 12 brings the sealing ring 6 into contact with the road surface. Then, the suction pump 8 extracts the gas from the sealing ring 6, causing it to adhere to the road surface. Next, the extension and retraction of the pressure rod 11 presses the sealing ring 10 firmly against the road surface, creating a double seal and reducing water leakage onto the road surface outside the sealing ring 10. Afterward, the filling pump inflates the filling space, creating further pressure on the outer side of the sealing ring 6 and the inner side of the sealing ring 10, ensuring a better fit between them. Furthermore, once the filling space is full, the air pressure within also prevents water from flowing through the sealing ring 6 into the filling space, achieving a superior seal.

[0032] In another embodiment of this utility model, both the inner pressure ring 20 and the outer pressure ring 17 include a fixed part 14 and a sliding part 15 slidably connected to the fixed part 14. A spring 16 is connected between the sliding part 15 and the fixed part 14. Through the telescopic arrangement of the inner pressure ring 20 and the outer pressure ring 17, the inner pressure ring 20 and the outer pressure ring 17 can adapt to the height between the mounting ring 4 and the road surface, better press the sealing ring 6 and the sealing ring 10, and improve the sealing effect.

[0033] In another embodiment of this utility model, a rubber ring 9 is fixed to the outside of the sealing ring 6. The upper surface of the rubber ring 9 has several annular protrusions 18, each with an inverted V-shaped cross-section. An annular groove 19 is formed between adjacent protrusions 18. When air is injected into the filling space, it is guided along the inclined surface of the protrusions 18, allowing the gas to flow more easily into the annular groove 19. This pressure then presses against the rubber ring 9, improving its sealing effect. A guide surface 13 is provided on the outside of the rubber ring 9. The outer side of the guide surface 13 slopes downwards. This design guides the gas flowing through the guide surface 13 to the road surface or the upper surface of the rubber ring 9, reducing the amount of gas entering through the gap between the end of the rubber ring 9 and the road surface.

[0034] In another embodiment of this utility model, a pressure sensor for detecting the air pressure in the filling space is installed on the mounting ring 4. The pressure sensor can be any existing sensor that can detect air pressure. By detecting the air pressure in the filling space through the pressure sensor, it can be determined whether the gas has filled the filling space.

[0035] In another embodiment of this utility model, the filling component includes a glue pump for applying sealant into the filling space. The mounting ring 4 has a channel 5 for the sealant to enter the filling space. The channel 5 for the sealant and the channel 5 for air intake can be the same channel 5, or multiple channels 5 can be designed for separate use. In actual design, inflating the filling space with air is a simple and convenient operation, while filling it with sealant will increase the detection time. The choice between inflating with air or filling with sealant can be made based on the actual situation. However, when the road surface is severely uneven, the sealing can be determined by detecting whether the sealing ring 6, sealing ring 10, and the part in contact with the road surface leak air and the degree of leakage. For example, if the air pressure sensor detects that the air pressure in the filling space cannot rise, it indicates a leak. In this case, the operator needs to reselect the detection point or re-seal by filling with sealant.

[0036] In another embodiment of this utility model, both the inner pressure ring 20 and the outer pressure ring 17 are detachably connected to the mounting ring 4. Specifically, both the inner pressure ring 20 and the outer pressure ring 17 are bolted to the mounting ring 4. Through the detachable connection of the inner pressure ring 20 and the outer pressure ring 17, after the filling space is filled with sealant, the sealant can be processed more conveniently after the inner pressure ring 20 and the outer pressure ring 17 are disassembled to a certain extent.

[0037] In another embodiment of this utility model, a road surface seepage detection device is also disclosed, including a bracket, a measuring cylinder 3 mounted on the bracket, and the sealing component described in any of the above embodiments. A mounting ring 4 is detachably connected to the bracket, and the inner side of the mounting ring 4 is used for the passage of the measuring cylinder 3. Specifically, the bracket includes a mounting plate 1 and a support leg 2 mounted on the lower end of the mounting plate 1. The mounting ring 4 is bolted to the lower side of the mounting plate 1. After the bracket is placed at a suitable position on the road surface, the inner sealing component, outer sealing component, and filling component on the mounting ring 4 complete the sealing, allowing water to be released from the measuring cylinder 3 to detect the road surface seepage rate.
