Description

Technical Field

[0001] This utility model relates to the field of pile foundation testing technology, and in particular to a bridge underwater pile foundation testing mechanism. Background Technology

[0002] With the continuous expansion of modern bridge construction, the number of bridges spanning rivers and seas is increasing. As a key foundation of bridge structure, the quality and stability of underwater pile foundations are directly related to the safe operation and service life of bridges. Due to the complex underwater environment, there are many influencing factors such as water erosion, corrosion, and geological changes. Traditional construction and testing methods are difficult to comprehensively and accurately assess the condition of pile foundations. In order to discover potential hidden dangers in a timely manner and ensure the safety of bridges throughout their entire life cycle, bridge underwater pile foundation testing institutions have emerged.

[0003] According to Chinese Utility Model Announcement No. CN222044295U, an underwater pile foundation testing mechanism for bridges is disclosed, comprising a float, a telescopic rod, and testing components. The float is used to float on the water surface and has a testing hole that is exposed above the water surface. The telescopic rod includes a first end and a second end opposite to each other. The first end is installed on the float, and the second end passes through the testing hole and is inserted underwater. The telescopic rod can extend and retract to adjust the depth of the second end underwater.

[0004] The current underwater pile foundation testing mechanism for bridges uses a telescopic rod to lower the testing device into the water. However, adjusting the telescopic rod involves a cumbersome process, requiring testing personnel to spend a significant amount of time and effort on adjustments. Furthermore, the telescopic rod is not convenient for adjusting all lengths. Therefore, this paper proposes an underwater pile foundation testing mechanism for bridges to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a bridge underwater pile foundation testing mechanism, which aims to improve the existing technology of using a telescopic rod to enter the water for testing. The telescopic rod has a complicated operation process for adjustment, requiring testing personnel to spend a lot of time and energy on debugging, and the telescopic rod is not convenient to adjust all lengths.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a bridge underwater pile foundation inspection mechanism, comprising a pile foundation body, a winding assembly provided on one side of the pile foundation body, an inspection device provided below the winding assembly, a camera provided inside the inspection device, a cleaning assembly provided on the top of the inspection device, the winding assembly including a float provided on one side of the pile foundation body, a mounting base fixedly connected to the top of the float, a motor fixedly connected to the right side of the mounting base, a winding drum fixedly connected to the output end of the motor, two pulleys fixedly connected to the left side wall of the mounting base, a reciprocating screw fixedly connected to the side wall of one of the pulleys, a guide plate threadedly connected to the surface of the reciprocating screw, a limit rod slidably connected inside the guide plate, and scale lines slidably connected to the surface of the guide plate;

[0007] As a further description of the above technical solution:

[0008] The cleaning assembly includes a mounting box fixedly connected to the top of the detection device. An electric push rod is fixedly connected inside the mounting box. A slider is fixedly connected to the output end of the electric push rod. A cleaning plate is fixedly connected to the side wall of the slider.

[0009] As a further description of the above technical solution:

[0010] The winding drum is rotatably connected inside the mounting base, and the reciprocating lead screw is rotatably connected inside the mounting base;

[0011] As a further description of the above technical solution:

[0012] The two pulleys are driven by a belt and are rotatably connected to the side wall of the mounting base;

[0013] As a further description of the above technical solution:

[0014] The limiting rod is fixedly connected inside the mounting base;

[0015] As a further description of the above technical solution:

[0016] One end of the scale line is fixedly connected to the surface of the winding drum, and the other end of the scale line is fixedly connected to the top of the detection device;

[0019] As a further description of the above technical solution:

[0020] The cleaning plate abuts against the surface of the camera, and the surface of the cleaning plate is provided with a sponge pad.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, through the structural design of the winding assembly, the winding drum and the reciprocating screw are driven by a belt pulley, cleverly constructing an orderly cable arrangement mechanism. During the unwinding process, the rotation of the reciprocating screw drives the guide plate to move along the limiting rod, so that the scale lines are evenly and neatly unwound from the winding drum, avoiding cable tangling and knotting, improving the smoothness of the inspection operation and the service life of the cable. At the same time, the scale lines intuitively show the unwinding length, making it easy for operators to accurately control the inspection depth, providing a strong guarantee for the accuracy of underwater pile foundation inspection data. This solves the problem in the prior art that the inspection device is placed in the water using a telescopic rod, and the adjustment of the telescopic rod is cumbersome, requiring the inspection personnel to spend a lot of time and energy on debugging, and the telescopic rod is not convenient for adjusting all lengths.

[0023] 2. In this utility model, through the structural design of the cleaning component, the mounting box provides a stable and highly protective integrated space for the internal components, which can effectively resist the erosion of the complex underwater environment. The electric push rod can output power accurately and flexibly according to actual needs to drive the slider. The slider can move smoothly along the predetermined track, driving the cleaning plate to clean the camera, preventing the lens from having debris attached to its surface due to time in the water, which would cause inconvenience in detection, thus enhancing the practicality of the underwater pile foundation detection mechanism for bridges.

[0029] 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.

[0030] Reference Figures 1-3This utility model provides an embodiment of an underwater bridge pile foundation inspection mechanism, comprising a pile foundation body 1, a winding assembly 2 on one side of the pile foundation body 1, providing power and control for the subsequent lowering and retrieval of the inspection device 3, an inspection device 3 below the winding assembly 2, a camera 4 inside the inspection device 3, and a cleaning assembly 5 on the top of the inspection device 3 for underwater cleaning of the camera 4. The winding assembly 2 includes a float 21 on one side of the pile foundation body 1, which can maintain a stable floating state on the water surface, ensuring the stability and reliability of the winding assembly 2 above water. A mounting base 22 is fixedly connected to the top of the float 21 to provide support for the winding assembly 2. A reliable installation support platform is provided to ensure the accuracy and stability of the position of each component during operation. A motor 23 is fixedly connected to the right side of the mounting base 22, and a winding drum 24 is fixedly connected to the output end of the motor 23. After the motor 23 starts, it efficiently converts electrical energy into mechanical energy, which drives the winding drum 24 to rotate through the output shaft. Two pulleys 25 are fixedly connected to the left side wall of the mounting base 22. A reciprocating screw 26 is fixedly connected to the side wall of one of the pulleys 25. Power transmission and speed conversion are realized through belt drive. When the winding drum 24 rotates, the reciprocating screw 26 rotates synchronously through belt drive. A guide plate 27 is threadedly connected to the surface of the reciprocating screw 26. The guide plate 27 is slidably connected to the limiting rod 28. During rotation, the reciprocating screw 26, using the principle of thread transmission, drives the guide plate 27 to perform linear reciprocating motion along the reciprocating screw 26. The limiting rod 28 provides precise guiding constraint for the movement of the guide plate 27, ensuring that the guide plate 27 maintains a linear motion trajectory during movement and avoiding deviation or shaking. The surface of the guide plate 27 is slidably connected to the scale line 29, allowing the scale line 29 to be evenly and neatly wound or unwound on the spool 24. The spool 24 is rotatably connected inside the mounting base 22, and the reciprocating screw 26 is rotatably connected inside the mounting base 22. The spool 24 and the reciprocating screw 26 are installed inside the mounting base 22, achieving flexible and stable operation. A fixed rotating connection ensures good transmission during long-term operation. Two pulleys 25 are driven by belts and are rotatably connected to the side wall of the mounting base 22. The two pulleys 25 are tightly driven by belts to ensure efficient and stable power transmission. The limit rod 28 is fixedly connected inside the mounting base 22 and provides reliable guidance support for the guide plate 27. One end of the scale line 29 is fixedly connected to the surface of the winding drum 24, and the other end is fixedly connected to the top of the detection device 3. The scale line 29 can convert the power of the motor 23 into the up and down movement of the detection device 3, realizing the detection coverage of different depth positions of the underwater pile foundation body 1.

[0031] Reference Figures 1-3The cleaning component 5 includes a mounting box 51 fixedly connected to the top of the detection device 3. The mounting box 51 serves as the carrier of the cleaning component 5, providing a stable working space for the internal components. An electric push rod 52 is fixedly connected inside the mounting box 51. A slider 53 is fixedly connected to the output end of the electric push rod 52. The electric push rod 52 pushes the slider 53 to move linearly inside the mounting box 51. This linear movement provides the power source for the wiping action of the cleaning plate 54. The cleaning plate 54 is fixedly connected to the side wall of the slider 53. The slider 53 is slidably connected inside the mounting box 51. The cleaning plate 54 abuts against the surface of the camera 4. A sponge pad is provided on the surface of the cleaning plate 54. The cleaning plate 54 moves synchronously with the slider 53. The cleaning plate 54 is in close contact with the surface of the camera 4. The sponge pad on the surface of the cleaning plate 54 effectively adsorbs impurities such as mud and microorganisms on the surface of the camera 4.

[0032] Working principle: The float 21 is floated on the water surface, and then the motor 23 is started. The motor 23 outputs power to drive the drum 24 to rotate. When the drum 24 rotates, the scale line 29 wound on its surface begins to descend or retract. At the same time, the drum 24 transmits power to the reciprocating screw 26 through the pulley 25, causing the reciprocating screw 26 to rotate synchronously. During the rotation of the reciprocating screw 26, the guide plate 27 moves smoothly on the surface of the reciprocating screw 26 under the guidance and constraint of the limit rod 28. The movement of the guide plate 27 ensures that the scale line 29 is evenly and orderly released or wound on the surface of the drum 24, avoiding cable tangling, knotting, etc. The detection device 3 is connected to the winding assembly 2 through the scale line 29, and the detection device moves according to the scale line. Line 29 is lowered to the position of the underwater pile foundation body 1. The camera 4 in the detection device 3 serves as the core detection component. It uses the principle of optical imaging to record the condition of the surface of the pile foundation body 1. When the camera 4 has been working underwater for a period of time, and the image clarity is affected by impurities such as mud and microorganisms attached to the surface, the electric push rod 52 is activated. The electric push rod 52 outputs linear thrust, which pushes the slider 53 to slide inside the mounting box 51. The sliding of the slider 53 drives the cleaning plate 54 to move synchronously. The cleaning plate 54 contacts the lens surface of the camera 4 and effectively removes impurities from the surface of the camera 4 through physical wiping, restoring its clear field of view and ensuring that the camera 4 continuously and stably obtains high-quality image information of the pile foundation body 1.
