Description

Technical Field

[0001] This application relates to the field of pile foundation testing equipment, and in particular to an underwater pile foundation testing equipment for bridges. Background Technology

[0002] When bridge foundations are submerged in water, the continuous erosion caused by the water flow can damage the foundations themselves, thus affecting the overall operational safety of the bridge. Therefore, divers need to periodically dive underwater with inspection equipment to check the appearance of the bridge foundations.

[0003] The published patent document CN216339732U discloses a device for inspecting the appearance of bridge pile foundations underwater. This patent document uses an adjustable-diameter ring clamp to fix the shooting device, which can inspect the appearance of bridge pile foundations of different diameters without the need for divers to repeatedly go underwater to change the appropriate appearance inspection device. However, when using this device, the ring clamp uses its own weight to move vertically downwards, which makes it difficult for the underwater camera to clearly capture the appearance of the pile foundation. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a bridge underwater pile foundation testing device, which overcomes the shortcomings of the prior art and aims to solve the problems in the prior art.

[0005] To achieve the above objectives, this application provides the following technical solution: an underwater bridge pile foundation testing device, comprising a pile foundation, an annular clamp slidably fitted onto the outer surface of the pile foundation, the annular clamp consisting of a semicircular ring one, a semicircular ring two, and a hinge, a positioning block fixedly installed on the inner wall of the annular clamp, an adjustment groove provided inside the positioning block, a spring fixedly connected inside the adjustment groove, an adjustment block fixedly connected to the other end of the spring, the end of the adjustment block away from the spring slidingly through the positioning block to the outside and fixedly installed with a mounting frame, a movable wheel rotatably connected inside the mounting frame, the movable wheel abutting against the pile foundation through a spring, and a submersible camera fixedly installed on the top of the annular clamp via a mounting base.

[0006] By adopting the above technical solution, since the annular clamp is composed of a semicircular ring one, a semicircular ring two, and a hinge, the annular clamp can be fitted onto the outer surface of the pile foundation. Through the cooperation between the positioning block, the adjusting groove, the spring, the adjusting block, the mounting frame, and the moving wheel, a horizontal force is applied to the moving wheel to make it abut against the pile foundation. This force generates a frictional force component opposite to the downward direction of the annular clamp, which can increase resistance and thus slow down the downward speed of the annular clamp. This allows the underwater camera to clearly photograph the appearance of the pile foundation and improve the detection effect.

[0007] As a preferred technical solution of this application, the number of the positioning block, adjusting groove, spring, adjusting block, mounting frame and moving wheel are all four and correspond one-to-one. The four positioning blocks, adjusting grooves, springs, adjusting blocks, mounting frames and moving wheels are evenly distributed in a circular array about the center of the pile foundation.

[0008] By adopting the above technical solution, forces can be applied simultaneously from four directions, increasing the contact area with the pile foundation and making the force uniform, which helps to slow down the downward speed of the ring clamp.

[0009] As a preferred technical solution of this application, the vertical cross-section of the adjustment block is T-shaped, and the adjustment block is slidably connected inside the adjustment groove.

[0010] By adopting the above technical solution, it is ensured that the adjusting block will not detach from the inside of the positioning block, and the spring can be protected to ensure that the spring will not bend during the downward movement of the annular clamp.

[0011] As a preferred technical solution of this application, the number of the mounting base and the underwater camera are both two, and the two mounting bases and the underwater camera are symmetrically distributed on both sides of the pile foundation.

[0012] By adopting the above technical solution, the underwater camera is fixed and positioned by the mounting bracket, ensuring the stability of the underwater camera. The cooperation between the two underwater cameras allows for a comprehensive image capture of the pile foundation's appearance, avoiding any omissions.

[0013] As a preferred technical solution of this application, the ends of the semicircular ring one and the semicircular ring two away from the hinge are both fixedly connected to a connecting block, and the two connecting blocks are fixedly connected together by bolts and nuts.

[0014] By adopting the above technical solution, the two semicircular rings, one and two, are fixedly assembled together to form a complete ring structure through the cooperation between the connecting block, bolt and nut.

[0015] As a preferred embodiment of this application, the connecting block, bolt, and nut are all made of stainless steel.

[0016] By adopting the above technical solution, the connecting blocks, bolts and nuts made of stainless steel have strong corrosion resistance, will not rust, and have a long service life.

[0017] As a preferred technical solution of this application, the outer walls of both the first and second semicircular rings are fixedly connected with handles, and the outer surface of the handles is provided with anti-slip textures.

[0018] By adopting the above technical solution, a handle is provided to facilitate divers carrying the detection device, and anti-slip textures are added to increase friction and prevent slippage.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In this invention, the annular clip is fitted onto the outer surface of the pile foundation through the cooperation of semicircular ring one, semicircular ring two, hinge, connecting block, bolt and nut. Through the cooperation of positioning block, adjusting groove, spring, adjusting block, mounting frame and moving wheel, a horizontal force is applied to the moving wheel to make it abut against the pile foundation. This force generates a frictional component opposite to the downward direction of the annular clip, which can increase resistance and thus slow down the downward speed of the annular clip. This allows the underwater camera to clearly photograph the appearance of the pile foundation and improve the detection effect.

[0021] With reference to the following description and accompanying drawings, specific embodiments of the present invention are disclosed in detail, indicating the ways in which the principles of the present invention can be adopted. It should be understood that the scope of the embodiments of the present invention is not limited thereto. Attached Figure Description

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] like Figure 1 - Figure 5 As shown, this embodiment provides a bridge underwater pile foundation testing device, including a pile foundation 1. An annular clamp 2 is slidably fitted onto the outer surface of the pile foundation 1. The annular clamp 2 consists of a semi-circular ring 201, a semi-circular ring 202, and a hinge 203. A positioning block 4 is fixedly installed on the inner wall of the annular clamp 2. An adjustment groove 5 is provided inside the positioning block 4. A spring 6 is fixedly connected inside the adjustment groove 5. An adjustment block 7 is fixedly connected to the other end of the spring 6. The end of the adjustment block 7 away from the spring 6 slides through the positioning block 4 to the outside and is fixedly installed with a mounting frame 8. A movable wheel 9 is rotatably connected inside the mounting frame 8. The movable wheel 9 abuts against the pile foundation 1 through the spring 6. The annular clamp 2... The top is fixedly mounted with a submersible camera 3 via a mounting base 13. In use, since the annular clip 2 is composed of a semi-circular ring 1 201, a semi-circular ring 2 202, and a hinge 203, the annular clip 2 can be fitted onto the outer surface of the pile foundation 1. Through the cooperation between the positioning block 4, the adjusting groove 5, the spring 6, the adjusting block 7, the mounting bracket 8, and the moving wheel 9, a horizontal force is applied to the moving wheel 9 to make it abut against the pile foundation 1. This force generates a frictional component opposite to the downward direction of the annular clip 2, which can increase resistance and thus slow down the downward speed of the annular clip 2, so that the submersible camera 3 can clearly photograph the appearance of the pile foundation 1 and improve the detection effect.

[0031] In this embodiment, as Figure 1 , 3 As shown in Figure 4, the number of positioning blocks 4, adjusting grooves 5, springs 6, adjusting blocks 7, mounting brackets 8, and moving wheels 9 are all set in four and correspond one-to-one. The four positioning blocks 4, adjusting grooves 5, springs 6, adjusting blocks 7, mounting brackets 8, and moving wheels 9 are evenly distributed in a circular array about the center of the pile foundation 1. In use, this allows for the simultaneous application of force from four directions, increasing the contact area with the pile foundation 1, making the force uniform, and helping to slow down the downward speed of the annular clamp 2.

[0032] In this embodiment, as Figure 4 As shown, the vertical cross-section of the adjusting block 7 is T-shaped. The adjusting block 7 is slidably connected inside the adjusting groove 5. During use, it ensures that the adjusting block 7 will not come out of the positioning block 4 and can protect the spring 6, ensuring that the spring 6 will not bend during the downward movement of the annular clip 2.

[0033] In this embodiment, as Figure 2As shown, there are two mounting bases 13 and two underwater cameras 3, and the two mounting bases 13 and the underwater cameras 3 are symmetrically distributed on both sides of the pile foundation 1. In use, the underwater cameras 3 are fixed by the mounting bases 13 to ensure the stability of the underwater cameras 3. The two underwater cameras 3 work together to take a comprehensive picture of the appearance of the pile foundation 1 and avoid any omissions.

[0034] In this embodiment, as Figure 2 and 5 As shown, both the first semicircular ring 201 and the second semicircular ring 202 are fixedly connected to a connecting block 10 at the end away from the hinge 203. The two connecting blocks 10 are fixedly connected together by bolts 11 and nuts 12. In use, the two semicircular rings 201 and 202 are fixedly assembled together to form a complete ring structure through the cooperation between the connecting blocks 10, bolts 11 and nuts 12.

[0035] In this embodiment, as Figure 5 As shown, the connecting block 10, bolt 11 and nut 12 are all made of stainless steel. When in use, the connecting block 10, bolt 11 and nut 12 made of stainless steel have strong corrosion resistance, will not rust, and have a long service life.

[0036] In this embodiment, as Figure 2 As shown, a handle 14 is fixedly connected to the outer wall of both the first semicircular ring 201 and the second semicircular ring 202. The outer surface of the handle 14 is provided with anti-slip texture. When in use, the handle 14 makes it convenient for divers to carry the detection device, and the anti-slip texture increases friction to prevent slipping.

[0037] The working principle of this utility model is as follows: When using the underwater pile foundation detection device for bridges according to this application, the annular clip 2 is sleeved on the outer surface of the pile foundation 1 through the cooperation between the semi-circular ring 1 201, the semi-circular ring 202, the hinge 203, the connecting block 10, the bolt 11 and the nut 12. Through the cooperation between the positioning block 4, the adjusting groove 5, the spring 6, the adjusting block 7, the mounting frame 8 and the moving wheel 9, a horizontal force is applied to the moving wheel 9 so that it abuts against the pile foundation 1. This force generates a frictional force component opposite to the downward sliding direction of the annular clip 2, which can increase the resistance and thus slow down the downward sliding speed of the annular clip 2, so that the underwater camera 3 can clearly photograph the appearance of the pile foundation 1 and improve the detection effect.
