Description

Technical Field

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

[0002] A bridge is a road built at a high altitude to provide transportation. The water permeability of a bridge is an important indicator of its stability. When testing the water permeability of a bridge, it is usually necessary to first clean up small stones and other debris on the bridge surface, so that the sealing ring of the testing device can contact the bridge surface. A temporary water storage tank is built at the water permeability testing point. Then, the water permeability stability of the bridge is evaluated by using the time required for water to permeate the bridge surface and cause the water level to drop by a certain amount.

[0003] For example, the authorized patent with announcement number CN 221405307 U (a bridge seepage detection device) includes an annular base. When performing seepage detection work, the bridge seepage detection device only needs to rotate the handle and the rotating rod. Through the cooperation of the worm gear and the worm, the threaded rod is rotated, which drives the lifting seat to move up and down, thereby moving the water injection pipe downward and squeezing the road surface through the lower pressure plate.

[0004] Although the existing technology mentioned above ensures the sealing between the lower pressure plate and the road surface through rubber sealing gaskets, when conducting bridge seepage detection, the sealing method between the bottom of the water injection pipe and the bridge surface relies solely on gravity compression, resulting in poor sealing performance and easy side leakage, which affects the accuracy of seepage detection. Therefore, there is an urgent need in the market to develop a bridge seepage detection device to help people solve the existing problems. Utility Model Content

[0005] The purpose of this utility model is to provide a bridge seepage detection device to solve the problem mentioned in the background art that when conducting bridge seepage detection, the sealing method between the bottom of the water injection pipe and the bridge surface relies solely on gravity compression, resulting in poor sealing performance, easy side leakage, and affecting the accuracy of seepage detection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bridge seepage detection device, comprising a platform, a water storage cylinder fixedly installed in the middle of the upper part of the platform, a telescopic pipe fixedly installed in the middle of the lower part of the platform, the telescopic pipe communicating with the water storage cylinder, an electric valve fixedly installed below the telescopic pipe, a water injection pipe fixedly installed below the electric valve, a pressure ring fixedly installed below the water injection pipe, a rubber sealing ring fixedly installed below the pressure ring, an annular groove provided on the lower end face of the rubber sealing ring, an air pump box fixedly installed on one side below the platform, an air pump fixedly installed inside the air pump box, an air extraction pipe provided below the air pump box, one end of the air extraction pipe extending into the interior of the air pump box and connected to the input end of the air pump, and the other end of the air extraction pipe fixedly connected to the water injection pipe.

[0007] Preferably, a base block is provided on the outer side of the water injection pipe, a detection hole is provided in the middle of the inside of the base block, and counterweight grooves are symmetrically provided on both sides of the inside of the base block.

[0008] Preferably, an outer ring plate is fixedly installed above the outer side of the water injection pipe, and side plates are symmetrically fixedly installed on both sides of the outer ring plate. A U-shaped plate is provided above the left side plate. The U-shaped plate is fixedly connected to the platform. An electric cylinder is fixedly installed inside the U-shaped plate. The push rod end of the electric cylinder slides to the bottom of the U-shaped plate and is fixedly connected to the side plate.

[0009] Preferably, a guide assembly is provided above the right-side side plate. The guide assembly includes a guide post and a guide cylinder. The guide cylinder is disposed above the guide post, and the upper end of the guide post slides into the interior of the guide cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model has a pressure ring and a rubber sealing ring at the bottom of the water injection pipe. The lower end face of the rubber sealing ring is designed with an annular groove. Combined with the negative pressure adsorption function of the air pump and the air extraction pipe, the air pump can extract the air in the water injection pipe after the water injection pipe comes into contact with the bridge surface, so that the rubber sealing ring is tightly adsorbed on the bridge surface under the negative pressure, which improves the sealing performance and avoids the occurrence of side leakage, thereby ensuring the accuracy of water seepage detection. Furthermore, the flexible material of the rubber sealing ring and the structural design of the annular groove further enhance the sealing effect, making it able to adapt to the unevenness of the bridge surface, thus improving the applicability and reliability of the device.

[0015] (2) The counterweight groove of this utility model makes it convenient to place additional counterweights into the bottom block. By increasing the weight of the bottom block, the stability of the device is enhanced, preventing the device from shifting due to external vibration or wind force during the detection process, and improving the reliability of the detection.

[0016] (3) The utility model can drive and adjust the downward pressure of the water injection pipe through the electric cylinder, ensuring that the pressure is uniform when the rubber sealing ring contacts the bridge surface, thus improving the sealing effect. The guide post and guide cylinder provide guidance for the up and down movement of the water injection pipe, ensuring that the water injection pipe always remains vertical during the movement, avoiding the problem of poor sealing caused by offset or tilt, and increasing practicality.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4An embodiment of this utility model provides a bridge seepage detection device, comprising a platform 1, a water storage cylinder 4 fixedly installed in the middle of the upper part of the platform 1, a telescopic pipe 6 fixedly installed in the middle of the lower part of the platform 1, the telescopic pipe 6 communicating with the water storage cylinder 4, an electric valve 7 fixedly installed below the telescopic pipe 6, a water injection pipe 8 fixedly installed below the electric valve 7, a pressure ring 17 fixedly installed below the water injection pipe 8, a rubber sealing ring 18 fixedly installed below the pressure ring 17, an annular groove 1801 provided on the lower end surface of the rubber sealing ring 18, an air pump box 13 fixedly installed on one side below the platform 1, the air pump box 13 is provided with a vent hole to facilitate the flow of internal and external air, an air pump is fixedly installed inside the air pump box 13, an air extraction pipe 14 is provided below the air pump box 13, one end of the air extraction pipe 14 extends into the interior of the air pump box 13 and is connected to the input end of the air pump, and the other end of the air extraction pipe 14 is fixedly connected to the water injection pipe 8.

[0024] During use, the bridge surface detection points are cleaned, then the water injection pipe 8 is moved above the detection points, and then the water injection pipe 8 is driven down so that the rubber sealing ring 18 below the pressure ring 17 contacts the bridge surface and is sealed by the rubber sealing ring 18. Then the air pump is started, and the air is extracted from the water injection pipe 8 through the air extraction pipe 14, so that the water injection pipe 8 is in a negative pressure state. As a result, the rubber sealing ring 18 with the annular groove 1801 can be tightly adsorbed onto the bridge surface, improving the sealing performance and preventing side leakage during bridge seepage detection, which would lead to inaccurate detection and increase the accuracy of bridge seepage detection.

[0025] Please see Figure 1 A base block 2 is provided on the outside of the water injection pipe 8. A detection hole 201 is provided in the middle of the inside of the base block 2. A counterweight groove 202 is symmetrically provided on both sides of the inside of the base block 2. A connecting plate 3 is fixedly installed on both the front and rear sides of the base block 2. The upper end of the connecting plate 3 is fixedly connected to the platform 1.

[0026] The counterweight groove 202 is designed to facilitate the placement of additional counterweights into the base block 2. By increasing the weight of the base block 2, the stability of the device is enhanced, preventing the device from shifting due to external vibrations or wind during the testing process, and further improving the reliability of the testing.

[0027] Please see Figure 1 An outer ring plate 9 is fixedly installed above the outer side of the water injection pipe 8. Side plates 10 are symmetrically fixedly installed on both sides of the outer ring plate 9. A U-shaped plate 11 is set above the left side plate 10. The U-shaped plate 11 is fixedly connected to the platform 1. An electric cylinder 12 is fixedly installed inside the U-shaped plate 11. The push rod end of the electric cylinder 12 slides to the bottom of the U-shaped plate 11 and is fixedly connected to the side plate 10.

[0028] The outer ring plate 9 and the side plate 10 provide additional support and fixation for the water injection pipe 8, enhancing the stability of the water injection pipe 8. The U-shaped plate 11 is fixedly connected to the platform 1, and the push rod end of the electric cylinder 12 is fixedly connected to the side plate 10, which can drive and adjust the downward pressure of the water injection pipe 8, ensuring uniform pressure when the rubber sealing ring 18 contacts the bridge surface, thus improving the sealing effect.

[0029] Please see Figure 2 A guide assembly is provided above the right side plate 10. The guide assembly includes a guide post 15 and a guide cylinder 16. The guide cylinder 16 is located above the guide post 15, and the upper end of the guide post 15 slides into the interior of the guide cylinder 16. The upper end of the guide cylinder 16 is fixedly connected to the platform 1, and the lower end of the guide post 15 is fixedly connected to the side plate 10.

[0030] The guide assembly consists of a guide post 15 and a guide cylinder 16. The guide post 15 slides into the interior of the guide cylinder 16, providing guidance for the up-and-down movement of the water injection pipe 8, ensuring that the water injection pipe 8 remains vertical during movement, and avoiding sealing problems caused by offset or tilt.

[0031] Please see Figure 1 The front end of the water storage cylinder 4 is provided with a slot, and a transparent plate 19 is fixedly installed inside the slot of the water storage cylinder 4. The front end surface of the transparent plate 19 is provided with scale lines.

[0032] A transparent plate 19 is set at the front end of the water storage tank 4, and scale lines are set on the transparent plate 19, so that the operator can intuitively observe the water level changes in the water storage tank 4 and keep track of the water consumption in real time during the detection process. This design not only improves the transparency of the detection, but also provides data reference for the operator and increases the practicality.

[0033] Please see Figure 4 A water inlet pipe 5 is fixedly installed on the upper side of one side of the water storage tank 4. An ultrasonic water level sensor 23 is fixedly installed inside the upper part of the water storage tank 4. The ultrasonic water level sensor 23 is a US40-60E ultrasonic water level sensor.

[0034] The water inlet pipe 5 facilitates the replenishment of water to the water storage tank 4, ensuring sufficient water supply during testing. The installation of the ultrasonic water level sensor 23 enables real-time monitoring of the water level in the water storage tank 4, accurately measuring water level changes and providing a reliable basis for the analysis of test data. This design not only improves the automation level of testing but also reduces the need for manual intervention, lowers the difficulty and error of operation, and improves testing efficiency and accuracy.

[0035] Please see Figure 1 Handles 22 are symmetrically fixedly installed on both sides of the platform 1. An equipment box 20 is fixedly installed on the top of the platform 1 along one side of the water storage tank 4. A switch panel 21 is fixedly installed on the top of the front end of the equipment box 20.

[0036] The handle 22 makes the device easy to carry and move, making it particularly suitable for multi-point testing needs at bridge inspection sites. The equipment box 20 provides centralized installation space for the device's control system and power supply, protecting the internal equipment from external environmental influences. The switch panel 21 allows operators to easily control the device's operating status, improving operational convenience.

[0037] Working principle: During use, the operator moves the device to the bridge inspection point using the handle 22 and cleans the surface of the inspection point. Then, the electric cylinder 12 is activated to drive the water injection pipe 8 downward, so that the rubber sealing ring 18 below the pressure ring 17 contacts the bridge surface. The air is extracted from the water injection pipe 8 by the air pump and air extraction pipe 14, so that the water injection pipe 8 is in a negative pressure state. This makes the rubber sealing ring 18 with the annular groove 1801 tightly adhere to the bridge surface, ensuring a seal. Then, sufficient water is added to the water storage tank 4 through the water inlet pipe 5. The electric valve 7 is opened, and the water in the water storage tank 4 flows into the water injection pipe 8 through the telescopic pipe 6, and then slowly seeps into the bridge surface inspection point. During the inspection, the ultrasonic water level sensor 23 monitors the water level change in the water storage tank 4 in real time, and the scale line on the transparent plate 19 shows the water consumption in a visual way, improving the accuracy and reliability of the inspection.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
