Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a road surface drainage testing device. Background Technology

[0002] Road surface drainage performance is one of the key factors affecting road service life and driving safety. Rainwater infiltration can lead to damage such as reduced strength of the road structure layers and surface peeling. Therefore, accurate testing of road surface drainage is crucial.

[0003] In existing technologies, the sealing of road surface permeability meters usually relies on manual application of waterproof sealing material. Operators need to first knead the sealing material into strips and then press and adhere it along the edge of the permeability meter base. This is not only cumbersome but also generally requires multiple testing operations, increasing the operation time and greatly reducing the efficiency of the test. In addition, the structure of traditional permeability meters consists of scattered components (such as counterweights) and fixed structures (such as water inlet pipes). Since the test operation is carried out outdoors, the scattered components increase the inconvenience of carrying them, while the fixed structure increases the space occupied, further leading to inconvenience of carrying them and hindering the use of the test equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a road surface drainage testing device, which has the advantages of being easy to operate and portable.

[0005] This utility model provides the following technical solution: a road surface drainage testing device, comprising: a base plate, an annular groove inside the base plate, a feed pipe fixedly connected to the side wall of the annular groove, and several through holes on the bottom surface of the annular groove, a cover plate installed on the feed pipe, a movable component inside the annular groove, a bottom groove at the center of the bottom surface of the base plate, an inner ring plate movably connected inside the bottom groove, an outer ring plate threadedly connected to the outer wall of the base plate, a fixed pipe fixedly connected to the center of the base plate and communicating with the bottom groove, a drain pipe fixedly connected to the top surface of the base plate, a control valve installed inside the fixed pipe and a top plate fixedly connected to its top end, four fixed rods evenly distributed and fixedly connected between the top plate and the base plate, a top groove communicating with the fixed pipe at the center of the top surface of the top plate, several water inlet pipes installed inside the top groove, several placement grooves on the bottom surface of the top plate, and two counterweights symmetrically arranged on the top surface of the base plate.

[0006] As a preferred embodiment of this utility model, the movable component includes a vertical tube. Two vertical tubes that penetrate the inner cavity of the annular groove are symmetrically fixedly connected to the top surface of the base plate. Each vertical tube is movably connected to a push rod, which is L-shaped. The bottom ends of the two push rods are fixedly connected to the same push plate, which is annular. A first sealing ring is fixedly connected to the inner and outer walls of the push plate. Several top blocks that match the through holes are fixedly connected to the bottom surface of the push plate.

[0007] As a preferred embodiment of this utility model, each water inlet pipe has an external threaded groove at its bottom end and an internal threaded groove at its top end. The external threaded grooves and internal threaded grooves on adjacent water inlet pipes are threaded together. The side wall of the water inlet pipe is provided with scale lines, and the top groove is threaded together with the external threaded groove.

[0008] As a preferred embodiment of this utility model, a second sealing ring is fixedly connected to the top surface of the external thread groove, and another second sealing ring is fixedly connected to the top surface of the internal thread groove.

[0009] As a preferred embodiment of this utility model, the inner wall of the placement groove is provided with threads, and the placement groove is matched with the external thread groove.

[0011] As a preferred embodiment of this utility model, the top diameter of the inner ring plate is smaller than its bottom diameter, and the bottom surfaces of the inner ring plate and the outer ring plate are on the same plane.

[0012] The beneficial effects of this utility model are:

[0013] 1. In this utility model, during the sealing operation for testing the drainage performance of the road surface, sealing material is added into the annular groove and the push rods on both sides are pressed simultaneously. The push rods drive the push plate to move in the annular groove, and the push plate discharges the sealing material from the through hole on the bottom surface of the base plate. This allows the sealing material to fill between the inner and outer ring plates, thus completing the sealing operation. Compared with traditional manual operation, this method is much more convenient and can effectively improve the overall testing efficiency.

[0014] 2. In this utility model, by aligning the external thread groove of the water inlet pipe with the placement groove and rotating it, the water inlet pipe is threadedly connected to the placement groove, completing the placement operation of all water inlet pipes, reducing the volume occupied by this testing device, making it convenient to carry. Furthermore, by aligning the round hole on the counterweight with the positioning rod, the positioning rod is inserted into the round hole, achieving a stable placement operation of the counterweight on the top surface of the base plate. Since the water inlet pipe is placed on the upper side of the counterweight, the counterweight can be prevented from detaching from the positioning rod, effectively improving the portability of this testing device.

Detailed Implementation

[0021] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Example

[0023] like Figures 1 to 5 As shown, a road surface drainage testing device includes: a base plate 1, an annular groove formed inside the base plate 1, a feed pipe 2 fixedly connected to the side wall of the annular groove, and several through holes 3 formed on the bottom surface of the annular groove; a cover plate 4 installed on the feed pipe 2; a movable component 5 disposed inside the annular groove; the movable component 5 includes vertical pipes 18; two vertical pipes 18 symmetrically fixedly connected to the top surface of the base plate 1, penetrating the inner cavity of the annular groove; and push rods 19 movably connected inside each vertical pipe 18; the push rods 19 are L-shaped and the two push rods 19 are L-shaped. The bottom end is fixedly connected to the same push plate 20, which is arranged in a ring. The inner and outer walls of the push plate 20 are fixedly connected to the first sealing ring 21. Several top blocks 22 that match the through holes 3 are fixedly connected to the bottom surface of the push plate 20. A bottom groove 6 is opened in the center of the bottom surface of the bottom plate 1. An inner ring plate 7 is movably connected in the bottom groove 6. An outer ring plate 8 is threadedly connected to the outer wall of the bottom plate 1. The top diameter of the inner ring plate 7 is smaller than its bottom diameter, and the bottom surfaces of the inner ring plate 7 and the outer ring plate 8 are on the same plane.

[0024] In this embodiment, during the sealing operation for testing the drainage performance of the road surface, the base plate 1 is inverted and the sealing material is added into the annular groove through the feed pipe 2. After the sealing material in the annular groove is filled, the cover plate 4 is placed on the feed pipe 2, and the base plate 1 is placed at the designated position on the road surface. Then, the operator simultaneously presses the push rods 19 on both sides. The push rods 19 drive the push plate 20 to move in the annular groove, and the push plate 20 discharges the sealing material from the through hole 3 on the bottom surface of the base plate 1. The sealing material continuously accumulates between the inner ring plate 7 and the outer ring plate 8. When the push rod 19 moves to a certain height, the pressing operation is stopped. At this time, the sealing material fills the space between the inner ring plate 7 and the outer ring plate 8, completing the sealing operation. Compared with the traditional manual operation, this method has good convenience and can effectively improve the overall testing efficiency.

[0025] In this embodiment, a fixed pipe 9 is fixedly connected to the center of the base plate 1 and is provided through the bottom groove 6. A drain pipe 10 is fixedly connected to the top surface of the base plate 1. A control valve 11 is installed in the inner cavity of the fixed pipe 9 and a top plate 12 is fixedly connected to the top end. Four fixed rods 13 are evenly distributed and fixedly connected between the top plate 12 and the base plate 1. A top groove 14 is opened at the center of the top surface of the top plate 12 and is provided through the fixed pipe 9. Several water inlet pipes 15 are installed in the top groove 14.

[0026] In this embodiment, by adding water to the inlet pipe 15 and opening the control valve 11, the water can enter the bottom trough 6 through the drain pipe 9. The internal gas can be discharged through the drain pipe 10, improving the detection accuracy. At this time, the road surface drainage data can be obtained by observing and calculating the reduction of water in the inlet pipe 15, thus realizing the detection function.

[0027] In this embodiment, a plurality of placement grooves 16 are provided on the bottom surface of the top plate 12. Each water inlet pipe 15 has an external thread groove 23 at its bottom end and an internal thread groove 24 at its top end. The external thread grooves 23 and internal thread grooves 24 on adjacent water inlet pipes 15 are threaded together. The side wall of the water inlet pipe 15 is provided with scale lines 25. The top groove 14 is threaded together with the external thread groove 23. The inner wall of the placement groove 16 is provided with threads. The placement groove 16 is matched with the external thread groove 23.

[0028] In this embodiment, the water inlet pipe 15 is removed from the top groove 14 and disassembled. The external thread groove 23 of each disassembled water inlet pipe 15 is aligned with the placement groove 26 and rotated so that the water inlet pipe 15 is threadedly connected to the placement groove 26. This operation completes the placement of all water inlet pipes 15, reducing the volume occupied by this detection device and making it easy to carry.

[0029] In this embodiment, a second sealing ring 26 is fixedly connected to the top surface of the external thread groove 23, and another second sealing ring 26 is fixedly connected to the top surface of the internal thread groove 24, which can improve the sealing performance of the water inlet pipe 15 connection and reduce water leakage.

[0030] In this embodiment, two counterweights 17 are symmetrically arranged on the top surface of the base plate 1. The counterweights 17 are U-shaped and have a circular hole 27. A positioning rod 28 is inserted into the circular hole 27. The positioning rod 28 is fixedly connected to the base plate 1, and a leather pad 29 is fixedly connected to the side wall of the positioning rod 28.

[0031] In this embodiment, the round hole 27 on the counterweight 17 is aligned with the positioning rod 28, so that the positioning rod 28 is inserted into the round hole 27, thereby achieving stable placement of the counterweight 17 on the top surface of the base plate 1. Furthermore, by placing the water inlet pipe 15 on the upper side of the counterweight 17, the counterweight 17 can be prevented from detaching from the positioning rod 28, effectively improving the portability of this detection device.

[0032] Implementation Plan: During the sealing operation for road surface drainage testing, the base plate 1 is inverted, and the sealing material is added into the annular groove through the feed pipe 2. After the sealing material is added to the annular groove, the cover plate 4 is placed on the feed pipe 2, and the base plate 1 is placed at the designated position on the road surface. Then, the operator simultaneously presses the push rods 19 on both sides. The push rods 19 drive the push plate 20 to move within the annular groove, using the push plate 20 to discharge the sealing material from the through hole 3 on the bottom surface of the base plate 1. The sealing material continuously accumulates between the inner ring plate 7 and the outer ring plate 8. When the push rods 19 have moved to a certain height, the pressing operation is stopped. At this point, the sealing material is filled between the inner ring plate 7 and the outer ring plate 8, completing the sealing operation. Compared with traditional manual operation, this method has good convenience and can effectively improve the overall testing efficiency. When the road surface drainage test is completed... After the entire testing process, the operator pushes the push rod 19 to the lowest position, so that the top block 22 is inserted into the through hole 3, and the sealing material in the annular groove is completely discharged. Then, the lower side of the base plate 1 is cleaned, and the round hole 27 on the counterweight block 17 is aligned with the positioning rod 28, so that the positioning rod 28 is inserted into the round hole 27, realizing the placement operation of the counterweight block 17 on the top surface of the base plate 1. Then, the water inlet pipe 15 is removed from the top groove 14 and disassembled. The external thread groove 23 of each disassembled water inlet pipe 15 is aligned with the placement groove 26 and rotated, so that the water inlet pipe 15 is threadedly connected to the placement groove 26. In this way, the placement operation of all water inlet pipes 15 is completed, reducing the volume occupied by this testing device. Furthermore, by placing the water inlet pipe 15 on the top side of the counterweight block 17, the counterweight block 17 can be prevented from detaching from the positioning rod 28, effectively improving the portability of this testing device.
