Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge seepage detection technology, specifically to a bridge seepage detection device. Background Technology
[0002] The water permeability of a bridge is an important indicator of its stability. Currently, when conducting water permeability tests on highway bridges, it is necessary to use a bridge testing water permeability tester.
[0003] Existing bridge seepage detection devices require pre-pressurization of the sealing gasket to ensure a tight fit with the bridge, thereby creating and sealing the detection space to prevent water leakage. However, this pressurization process is mostly done manually and requires multiple cyclical operations. This results in lower performance and uneven pressure application, which can affect the sealing and thus the detection results. Therefore, there is an urgent need for a bridge seepage detection device to solve these problems. Utility Model Content

[0014] (III) Beneficial Effects
[0015] Compared with the prior art, this utility model has the following advantages:

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0023] like Figures 1-3 As shown, a bridge seepage detection device in this embodiment includes a water injection pipe 3, a ring-shaped drive box 5 installed on the water injection pipe 3, a gear 14 installed inside the drive box 5, a drive motor 8 connected to the middle of one end of the gear 14, which can drive the gear 14 to rotate, a gear ring 15 connected to one side of the gear 14, which can drive the pressure ball 13 to rotate, a T-shaped limiting cavity 16 fixedly opened on the bottom wall of the drive box 5 at a position corresponding to the gear ring 15, which limits the rotation performance of the gear ring 15 while ensuring its rotation performance, and four sets of electric push rods 11 are circumferentially distributed at the bottom end of the gear ring 15. A synchronous drive device is installed between the four electric push rods, which are mechanically connected to each other to achieve synchronous movement. A pressure block 12 is fixed on the movable part of the electric push rod 11, and a pressure ball 13 is installed at the bottom of the pressure block 12. Under the action of the electric push rod 11, pressure can be applied to the soft silicone pad 10. A horn-shaped flow guide shroud 9 is provided at the bottom of the water injection pipe 3. A soft silicone pad 10 is provided on the outer edge of the flow guide shroud 9, which can fit tightly with the bridge surface to form a detection space. The power supply mechanism of the electric push rod 11 can be realized by the existing mature conductive slip ring.
[0024] like Figures 1-3 In this embodiment, gear 14 is rotatably mounted inside drive box 5, and the output shaft of drive motor 8 is fixedly connected to gear 14. Gear 14 meshes with gear ring 15, and gear ring 15 is rotatably connected to limiting cavity 16. Electric push rod 11 is fixed on the bottom wall of gear ring 15. Pressure block 12 is mounted on the movable part of electric push rod 11 by screws. Pressure ball 13 is rotatably connected to pressure block 12. Flow guide shroud 9 is formed on water injection pipe 3, and soft silicone pad 10 is adhered to the outer wall of flow guide shroud 9. During the detection process, the controller in control box 6 can control the flow. Four sets of electric push rods 11 synchronously drive the pressure block 12 to move downward, thereby bringing the pressure ball 13 into contact with the soft silicone pad 10 and applying pressure to it. At the same time, the drive motor 8 drives the gear 14 to rotate, and the gear 14 drives the pressure ball 13 to rotate along the surface of the soft silicone pad 10 through the gear ring 15, thereby applying pressure periodically. This method replaces manual pressure application, which saves time and effort on the one hand, and ensures the uniformity of the pressure intensity on the other hand, thus ensuring the adhesion and sealing performance between the soft silicone pad 10 and the bridge, and has high performance in use.
[0025] like Figures 1-3 In this embodiment, the flow guide shroud 9 is formed on the water injection pipe 3, and the soft silicone pad 10 is bonded to the outer wall of the flow guide shroud 9. A control box 6 is installed on one side wall of the drive box 5. The control box 6 contains a battery pack and a controller. Multiple sets of brackets 7 are distributed in a circular pattern on the outer wall of the drive box 5. A measuring cup 1 is set at the top of the water injection pipe 3. A scale line 2 is bonded to one side wall of the measuring cup 1. A solenoid valve 4 is also installed on the water injection pipe 3. The control box 6 controls the operation of the device. The brackets 7 can support the device. When the soft silicone pad 10 is tightly attached to the bridge surface, the water injection pipe 3 is opened by the solenoid valve 4. At this time, the water in the measuring cup 1 is injected into the bridge surface through the water injection pipe 3 and the flow guide shroud 9. The water permeability of the bridge surface is detected by observing the remaining water in the measuring cup 1 through the scale line 2.
[0026] The specific implementation process of this embodiment is as follows: During use, the device is placed at the detection position via the bracket 7. Then, the control box 6 controls the drive motor 8 and four sets of electric push rods 11 to work synchronously. The electric push rods 11 drive the pressure block 12 to move down, thereby making the pressure ball 13 contact the soft silicone pad 10 and apply pressure to it. At the same time, the drive motor 8 drives the gear 14 to rotate. The gear 14 drives the pressure ball 13 to rotate along the surface of the soft silicone pad 10 through the gear ring 15, thereby applying pressure periodically. This method replaces manual pressure application, which saves time and effort on the one hand, and ensures the uniformity of the pressure intensity on the other hand, thereby ensuring the adhesion and sealing performance of the soft silicone pad 10 to the bridge. After the soft silicone pad 10 is tightly attached to the bridge surface, the water injection pipe 3 is opened through the solenoid valve 4. At this time, the water in the measuring cup 1 is injected into the bridge surface through the water injection pipe 3 and the guide cover 9. The remaining water in the measuring cup 1 is observed through the scale line 2 to detect the water seepage rate of the bridge surface.
