Underwater pile foundation scour and corrosion monitoring equipment

Abstract

This utility model discloses an underwater pile foundation erosion corrosion monitoring device, belonging to the field of corrosion monitoring technology. It includes: two fixed columns with a connecting rod fixedly installed between them; and a displacement component disposed within the cavity of each fixed column. In this utility model, the displacement component, through the forward and reverse rotation of a synchronous motor, enables the threaded column to rotate in both directions. This, in turn, causes the threaded seat to move the mounting plate up and down within the fixed column under the action of the thread. This, in turn, causes the sealing cover to automatically monitor the pile foundation using an underwater ultrasonic thickness gauge, thereby increasing the monitoring range of the device and ensuring the effectiveness of underwater pile foundation erosion corrosion monitoring. It also improves the monitoring efficiency. By fixing the monitoring device in the water using the fixed columns, personnel are no longer required to hold the device underwater, reducing the time personnel spend in the water and lowering the risk of underwater pile foundation erosion corrosion monitoring.

Description

Technical Field

[0001] This utility model belongs to the field of corrosion monitoring technology, and in particular relates to underwater pile foundation scour corrosion monitoring equipment. Background Technology

[0002] Underwater pile foundations are a type of foundation structure formed by pouring concrete into water through a guide pipe. They have the characteristics of self-leveling, self-compacting, and vibration-free operation. They are mainly used in underwater or underground engineering projects. Because underwater pile foundations are located in water for a long time, they are subject to water erosion and corrosion. Therefore, it is necessary to locate and monitor the corrosion of underwater pile foundations.

[0003] Currently, the most commonly used monitoring equipment is the underwater ultrasonic thickness gauge. This monitoring equipment requires a person to hold the device and dive into the water to monitor the corrosion of the underwater pile foundation. During the monitoring process, the personnel need to be in the water for a long time. On the one hand, the personnel will drift due to the water flow, which can reduce the monitoring effect. On the other hand, the personnel are in the water for a long time, which is dangerous. Therefore, underwater pile foundation erosion corrosion monitoring equipment has been developed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that current testing equipment requires manual handheld equipment to be placed in water for monitoring, which is somewhat dangerous, and proposes an underwater pile foundation erosion corrosion monitoring device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an underwater pile foundation erosion corrosion monitoring device, comprising: two fixed columns, each fixedly mounted with a handle on its upper surface, a connecting rod fixedly mounted between the two fixed columns, a cavity inside each fixed column, and drainage holes on the outer surface of each fixed column; a displacement component, disposed within the cavity of the fixed column, used to drive the monitor to move; and a cleaning component, disposed on the outer surface of the displacement component, used to clean the outer surface of the pile foundation; wherein, the displacement component includes two synchronous motors, the two synchronous motors rotating at the same frequency, the upper surfaces of the two synchronous motors being fixedly connected to the inner walls of the top surfaces of the cavities of the two fixed columns, and threaded posts fixedly mounted on the output ends of the synchronous motors.

[0006] As a further description of the above technical solution: The threaded post is located in the cavity of the fixed post. The thread pitch on the outer surface of the two threaded posts is the same, and threaded seats are threadedly installed on the outer surface of both threaded posts.

[0007] As a further description of the above technical solution: An mounting plate is fixedly installed on the side wall of the threaded seat. The outer surfaces of the two fixed columns are provided with stroke grooves, and the two stroke grooves correspond to each other. One end of the mounting plate is fixedly connected to the outer surface of the other threaded seat through the stroke groove. The threaded column and the threaded seat cooperate to realize the up and down movement of the mounting plate.

[0008] As a further description of the above technical solution: The mounting plate has screw holes on its side wall, and a sealing cover is installed on the mounting plate by bolts. An underwater ultrasonic thickness gauge is fixedly installed on the inner wall of the sealing cover. The sealing cover seals the underwater ultrasonic thickness gauge and reduces the contact time between the underwater ultrasonic thickness gauge and water.

[0009] As a further description of the above technical solution: The cleaning assembly includes a connecting plate, which is fixedly connected to the mounting plate by bolts. A limit cover is fixedly installed on the side wall of the connecting plate, and a connecting spring is fixedly installed on the inner side wall of the limit cover.

[0010] As a further description of the above technical solution: A movable plate is fixedly installed at one end of the connecting spring. The outer surface of the movable plate is slidably connected to the inner wall of the limiting cover. A fixed cylinder is fixedly installed on the inner wall of the movable plate. One end of the fixed cylinder extends to the outside of the side wall of the connecting plate, and the other end of the fixed cylinder extends to the outside of the limiting cover. The connecting spring and the movable plate can cause the fixed cylinder to deform a short distance.

[0011] As a further description of the above technical solution: A threaded sleeve is rotatably installed at one end of the fixed cylinder, and a threaded rod is threaded on the inner wall of the threaded sleeve. One end of the threaded rod passes through the interior of the fixed cylinder, and a scraper is fixedly installed at one end of the threaded rod. The threaded sleeve and the threaded rod cooperate to adjust the position of the scraper, and the connecting spring can ensure that the scraper is always in contact with the outer surface of the pile foundation.

[0012] As a further description of the above technical solution: The front half of the threaded rod is a smooth round rod, and the rear half is provided with threads that match the threaded sleeve. A limit strip is fixedly installed on the front half of the threaded rod, and a limit groove is provided on the inner wall of the fixed cylinder. The threaded rod is limited by the cooperation of the limit strip and the limit groove. The limit groove and the limit strip restrict the rotation of the threaded rod so that the threaded rod does not rotate with the threaded sleeve.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, by setting a displacement component, the synchronous motor rotates forward and backward to realize the forward and reverse rotation of the threaded column. Under the action of the thread, the threaded seat drives the mounting plate to move up and down inside the fixed column. This causes the sealing cover to drive the underwater ultrasonic thickness gauge to automatically monitor the vertical displacement of the pile foundation. This improves the monitoring range of the monitoring equipment, thereby ensuring the monitoring effect of underwater pile foundation erosion corrosion. It also improves the monitoring efficiency of the monitoring equipment. By fixing the monitoring equipment in the water with the fixed column, there is no need for personnel to hold the monitoring equipment in the water, reducing the time personnel spend in the water and reducing the danger of underwater pile foundation erosion corrosion monitoring.

[0014] 2. In this utility model, by setting up a cleaning component, when the mounting plate moves, the scraper is displaced on the surface of the pile foundation by the cooperation of components such as the connecting plate, limiting cover, connecting spring, threaded sleeve and threaded rod. This enables the monitoring equipment to automatically clean the monitoring position before monitoring the corrosion of the pile foundation, effectively reducing the error caused by moss and other impurities to the monitoring results, and further ensuring the monitoring accuracy of the monitoring equipment.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] In specific implementation, such as Figures 1-4 As shown, this utility model provides a technical solution: an underwater pile foundation erosion corrosion monitoring device, comprising two fixed columns 1, each fixedly mounted with a handle on its upper surface, a connecting rod 2 fixedly mounted between the two fixed columns 1, a cavity inside each fixed column 1, and drainage holes on its outer surface; a displacement component 3, disposed within the cavity of the fixed column 1, for driving the monitor to move; and a cleaning component 5, disposed on the outer surface of the displacement component 3, for cleaning the outer surface of the pile foundation; wherein, the displacement component 3 includes two synchronous motors 31, the two synchronous motors 31 rotating at the same frequency, and the upper surfaces of the two synchronous motors 31 respectively connected to the two fixed columns 1. The inner wall of the top surface of the chamber of the fixed column 1 is fixedly connected. The output end of the synchronous motor 31 is fixedly installed with a threaded column 32. The threaded column 32 is located in the chamber of the fixed column 1. The thread pitch of the two threaded columns 32 is the same. The outer surface of the two threaded columns 32 is threadedly installed with a threaded seat 33. The side wall of the threaded seat 33 is fixedly installed with a mounting plate 34. The outer surface of the two fixed columns 1 is provided with a stroke groove. The two stroke grooves correspond to each other. One end of the mounting plate 34 is fixedly connected to the outer surface of the other threaded seat 33 through the stroke groove. The side wall of the mounting plate 34 is provided with a screw hole. The mounting plate 34 is bolted to a sealing cover 4. The inner wall of the sealing cover 4 is fixedly installed with an underwater ultrasonic thickness gauge.

[0022] By inserting the fixed column 1 into the appropriate position in the water with the handle, the monitoring end of the underwater ultrasonic thickness gauge inside the sealing cover 4 is aligned with the pile foundation. The synchronous motors 31 inside the two fixed columns 1 start working. At this time, the synchronous motors 31 drive the threaded column 32 to rotate forward in the cavity of the fixed column 1. Under the action of the thread, the threaded seat 33 will move downward to the threaded column 32. When the threaded column 32 rotates in the reverse direction, the threaded seat 33 will move upward to the threaded column 32. When the threaded seat 33 moves, it will drive the sealing cover 4 and the connecting plate 51 to move synchronously through the mounting plate 34. When the sealing cover 4 moves, it drives the underwater ultrasonic thickness gauge to monitor the pile foundation. This can fix the corrosion monitoring equipment in the water, eliminating the need for long-term manual handling and reducing the time operators spend in the water.

[0023] like Figure 4As shown, the cleaning assembly 5 includes a connecting plate 51, which is fixedly connected to the mounting plate 34 by bolts. A limit cover 52 is fixedly installed on the side wall of the connecting plate 51. A connecting spring 53 is fixedly installed on the inner side wall of the limit cover 52. A movable plate 54 is fixedly installed at one end of the connecting spring 53. The outer surface of the movable plate 54 is slidably connected to the inner wall of the limit cover 52. A fixing cylinder 55 is fixedly installed on the inner wall of the movable plate 54. One end of the fixing cylinder 55 extends to the outside of the side wall of the connecting plate 51, and the other end of the fixing cylinder 55 extends to... Outside the limiting cover 52, a threaded sleeve 56 is rotatably installed at one end of the fixed cylinder 55. A threaded rod 57 is threadedly installed on the inner wall of the threaded sleeve 56. One end of the threaded rod 57 passes through the interior of the fixed cylinder 55. A scraper 58 is fixedly installed at one end of the threaded rod 57. The front half of the threaded rod 57 is a smooth round rod, and the rear half is provided with threads that match the threaded sleeve 56. A limiting strip is fixedly installed on the front half of the threaded rod 57. A limiting groove is provided on the inner wall of the fixed cylinder 55. The threaded rod 57 is limited by the cooperation of the limiting strip and the limiting groove.

[0024] By rotating the threaded sleeve 56, the threaded rod 57, under the action of the thread, is displaced inside the fixed cylinder 55 under the limitation of the limiting groove and the limiting strip. This causes the threaded rod 57 to drive the scraper 58 to move. When the side wall of the scraper 58 is in contact with the pile foundation, the rotation of the threaded sleeve 56 stops. Due to the self-locking property of the thread, the position of the scraper 58 is fixed by fixing the threaded rod 57. When the connecting plate 51 moves, it drives the scraper 58 to move on the surface of the pile foundation. Under the action of the connecting spring 53 and the movable plate 54, the scraper 58 is always in contact with the surface of the pile foundation. When the scraper 58 moves, it cleans the moss and other impurities adhering to the surface of the pile foundation, thus cleaning the outer surface of the pile foundation before monitoring and reducing the impact of moss and other impurities on the monitoring results.

[0025] Working principle: By inserting the fixed column 1 into the appropriate position in the water using the handle, the monitoring end of the underwater ultrasonic thickness gauge inside the sealing cover 4 is aligned with the pile foundation. Then, by rotating the threaded sleeve 56, the threaded rod 57 is displaced inside the fixed cylinder 55 under the action of the thread, limited by the limiting groove and the limiting strip. This causes the threaded rod 57 to drive the scraper 58 to move. When the side wall of the scraper 58 is in contact with the pile foundation, the rotation of the threaded sleeve 56 stops. Due to the self-locking property of the thread, the position of the scraper 58 is fixed by fixing the threaded rod 57. Then, the synchronous motor 31 inside the two fixed columns 1 starts working. At this time, the synchronous motor 31 drives the threaded column 32 to move in the fixed position. When the fixed column 1 rotates in the forward direction, the threaded seat 33 moves downward to the threaded column 32 under the action of the thread. When the threaded column 32 rotates in the reverse direction, the threaded seat 33 moves upward to the threaded column 32. When the threaded seat 33 moves, it drives the sealing cover 4 and the connecting plate 51 to move synchronously through the mounting plate 34. When the sealing cover 4 moves, it drives the underwater ultrasonic thickness gauge to monitor the pile foundation. When the connecting plate 51 moves, it drives the scraper 58 to move on the surface of the pile foundation. Under the action of the connecting spring 53 and the movable plate 54, the scraper 58 always keeps in contact with the surface of the pile foundation. When the scraper 58 moves, it cleans the moss and other impurities adhering to the surface of the pile foundation.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
