Description

Technical Field

[0001] This application belongs to the technical field of pile foundation acoustic logging pipe cleaning equipment, specifically relating to a pile foundation acoustic logging pipe unblocking device. Background Technology

[0002] A pile foundation sonic logging tube is a steel pipe used in pile foundation construction. It is primarily used to inspect the quality of the pile foundation concrete using ultrasonic testing methods after the concrete has been poured. This steel pipe is generally pre-embedded in the pile foundation, usually installed together with the reinforcing steel. The main purpose of the pile foundation sonic logging tube is to provide a channel for ultrasonic testing, allowing inspectors to accurately assess the density, integrity, and presence of defects in the pile foundation concrete. This is crucial for ensuring the safety and durability of the pile foundation structure.

[0003] During actual construction, the complex and variable site environment, such as improper operation during concrete pouring or poor concrete fluidity, can cause concrete to enter the sonic logging pipes in the pile foundation, resulting in blockage. Once the sonic logging pipes become blocked, it will severely affect subsequent ultrasonic testing, making it impossible to accurately obtain data on the internal condition of the pile foundation, which may consequently affect the overall quality assessment of the project. Furthermore, if the sonic logging pipes need to be rearranged or other remedial measures are taken, it will not only increase additional costs but may also lead to project delays, affecting construction progress and cost control.

[0004] Currently, the common practice for clearing blockages in sonic logging pipes for pile foundations is to insert a water pipe into the pipe and pump water to flush the inner wall. However, this method has technical limitations, including limited flushing locations and insufficient cleaning. Furthermore, manually changing the flushing location not only increases operational difficulty but also wastes manpower, resulting in low efficiency and potential safety hazards. Utility Model Content

[0005] To solve the above-mentioned technical problems, this application provides a device for clearing obstructions in pile foundation sonic logging pipes, which is achieved through the following technical solution:

[0006] A pile foundation acoustic logging pipe clearing device includes: a cylinder with a water inlet at one end and a water outlet at the other end; a rotating cleaning component rotatably connected to the end of the cylinder near the water outlet, including a diversion hood that is connected through the water outlet, a plurality of water outlet pipes disposed on the diversion hood, and a driving component that is fixedly connected to the diversion hood and used to drive the diversion hood to rotate relative to the cylinder.

[0007] Preferably, the cylinder is provided with a fixed shaft that passes through the central axis of the outlet; the driving component includes a rotating component that is rotatably connected to the outer wall of the fixed shaft.

[0008] Preferably, the driving component further includes a plurality of propeller blades disposed on the outer surface of the rotating component, the propeller blades moving circumferentially around a fixed axis under the action of the water flowing out of the outlet.

[0009] Preferably, a motor connected to the rotating component is installed inside the fixed shaft.

[0010] Preferably, the rotating cleaning component is further provided with a longitudinally arranged scraper on the side near the cylinder; the scraper protrudes from the diversion hood.

[0011] Preferably, the cylinder is further provided with a conveying pipe connecting the water inlet and the water outlet; the outer wall of the conveying pipe and the inner wall of the cylinder form a space for storage.

[0012] Preferably, the upper end of the cylinder is provided with a drain outlet that is connected to the storage space; the pipe wall of the conveying pipe is also provided with a guide hole for introducing part of the water into the storage space.

[0013] Preferably, the delivery pipeline includes a filter pipe and a guide pipe connected to each other.

[0014] Compared with the prior art, this application has the following beneficial effects:

[0015] The pile foundation sonic logging pipe unblocking device of this application, by setting a rotating cleaning component at the end of the cylinder near the water outlet, can effectively divert water through the connection between the water outlet pipe and the water inlet. Furthermore, by setting a driving component connected to the diversion hood, the water outlet pipe can be indirectly driven to rotate relative to the cylinder, thereby generating a spiral discharge water flow. Therefore, by embedding the unblocking device of this application into the pile foundation sonic logging pipe, all-round flushing of the inner wall of the pile foundation sonic logging pipe can be achieved, ensuring the removal of internal dirt and blockages, and improving the unblocking effect and efficiency.

[0016] This application features a fixed shaft on the cylinder body, and a corresponding rotating component that rotatably engages with the outer wall of the fixed shaft. The fixed connection between the rotating component and the diversion hood significantly reduces the connection pressure at the rotatable connection point between the rotating cleaning component and the cylinder body. This design not only improves the overall operational stability of the pile foundation sonic logging pipe unblocking device but also ensures a stable flow of water through the diversion hood, enhancing both cleaning and unblocking effects.

[0017] This application utilizes a propeller blade on the outer surface of the rotating component. By leveraging the potential energy of the water flowing from the inlet to the outlet, the propeller blade rotates circumferentially around a fixed axis, thereby rotating the diverter shroud connected to the driving component and forming a spiral-shaped water discharge. This design fully utilizes the potential energy of the water flow and is significantly environmentally friendly. By adjusting the water flow velocity at the inlet, most blockages can be effectively resolved. Furthermore, this application incorporates a motor, providing stronger power support in cases of severe concrete blockage, ensuring complete removal of the blockage and thus comprehensively improving the applicability and efficiency of the pile foundation acoustic logging pipe clearing device.

[0018] This application adds a scraper to the side of the rotating cleaning component near the cylinder. After initial wetting and unblocking by the water flow formed by the water outlet pipe, the scraper can perform a secondary scraping on the inner wall of the pile foundation sonic logging tube. This design can thoroughly remove the blockages attached to the inner wall of the pile foundation sonic logging tube and reduce the impact of the attached substances on the pile foundation quality inspection.

[0019] This application utilizes the remaining space by setting guide holes in the pipe wall of the conveying pipeline and a drain outlet at the upper end of the cylinder to achieve a third cleaning of the inner wall of the pile foundation sonic logging pipe. Specifically, even after initial scraping with a scraper, some residue may still remain on the inner wall of the pile foundation sonic logging pipe. By continuously injecting water through the water inlet, a certain water pressure can be formed in the remaining space. When the remaining space is full, the water will be discharged from the drain outlet, thoroughly flushing the residue on the inner wall of the pile foundation sonic logging pipe and ensuring the cleanliness of the inner wall.

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Those skilled in the art will be able to implement the present invention based on these descriptions. Furthermore, the embodiments of the present invention described below are generally only a part of the embodiments of the present invention, and not all of the embodiments. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

[0029] Example 1

[0030] Please see Figures 1-7 This embodiment discloses a device for clearing obstructions in a pile foundation acoustic logging pipe, comprising:

[0031] The cylinder 100 has a water inlet 110 at its upper end and a water outlet 120 at its lower end. Inside the cylinder 100, a conveying pipe 140 connects the water inlet 110 and the water outlet 120. The conveying pipe 140 has a filter pipe 142 and a guide pipe 143 arranged sequentially from top to bottom. In this embodiment, the filter pipe 142 and the guide pipe 143 are inserted together. Therefore, during use, the water inlet 110 is connected to a water source, and the water flows sequentially through the filter pipe 142 and the guide pipe 143.

[0032] In this embodiment, a mounting plate is welded to the end of the guide pipe 143 away from the filter pipe 142. The outlet 120 is mounted on the mounting plate. The outlet 120 is coaxial with the central axis of the guide pipe 143, and the diameter of the guide pipe 143 is larger than the diameter of the outlet 120. A guide hole 141 is also provided on the side wall of the guide pipe 143 near the outlet 120. A storage space is formed between the outer wall of the conveying pipe 140 and the inner wall of the cylinder 100. A drain outlet 150 is also provided at the upper end of the cylinder 100, which is connected to the storage space. Therefore, with the design of the outlet 120 and even the guide hole 141, after the water flows to the guide pipe 143, part of the water will flow out along the outlet 120, and the other part of the water will flow along the guide hole 141 to the storage space. As water is continuously injected, the water in the space continuously increases until it overflows from the drain outlet 150. The overflowing water can flush the inner wall of the pile foundation sonic logging pipe. To achieve a good flushing effect, in this embodiment, the inlet 110 is set at the center of the upper end of the cylinder 100, and the drain outlets 150 are set in three groups around the cylinder 100, with the drain outlets 150 facing outwards.

[0033] The rotating cleaning component 200 is rotatably connected to the end of the cylinder 100 near the outlet 120, and includes a diversion hood 210 that is connected through the outlet 120, and three sets of outlet pipes 220 evenly distributed on the diversion hood 210. To ensure effective scouring of the inner wall of the pile foundation sonic logging pipe by the water outlets 220, in this embodiment, the outlets of the outlet pipes 220 are arranged facing outwards. During use, the water flowing out of the outlet 120 will flow into the diversion hood 210 and finally be discharged through the three sets of outlet pipes 220. To achieve multi-angle and all-round scouring of the inner wall of the pile foundation sonic logging pipe, in this embodiment, the rotating cleaning component 200 also includes a driving component 230 fixedly connected to the diversion hood 210 and used to drive the diversion hood 210 to rotate relative to the cylinder 100.

[0034] A fixing frame is provided on the inner wall of the outlet 120 of the cylinder 100, and a fixing shaft 130 is provided on the outer side of the fixing frame, penetrating the central axis of the outlet 120. The driving component 230 includes a rotating component 231 that rotatably connects with the outer wall of the fixing shaft 130. The driving component 230 also includes three sets of propeller blades 232 disposed on the outer surface of the rotating component 231. An annular limiting groove is provided between the mounting plate at the lower end of the cylinder 100 and the inner wall of the cylinder 100, and a connecting ring that rotatably contacts the annular limiting groove is provided at the upper end of the diverter shroud 210. Therefore, under the action of the water flowing out of the outlet 120, the propeller blades 232 move circumferentially around the fixing shaft 130. Furthermore, with the fixed relationship between the driving component 230 and the diverter shroud 210, a rotatable connection between the rotating cleaning component 200 and the cylinder 100 can be achieved.

[0035] Furthermore, in this embodiment, the rotating cleaning component 200 is also provided with a scraper assembly sleeved on the lower end of the connecting ring near the cylinder 100. The scraper assembly includes a ring and scrapers 240 evenly distributed on the outer wall of the ring. The scrapers 240 protrude from the diversion hood 210 and are longitudinally distributed. During use, the rotating cleaning component 200 can scrape off concrete and other adhering materials on the inner wall of the pile foundation acoustic logging pipe.

[0036] In this embodiment, the pile foundation sonic logging pipe clearing device is used by connecting a water source to the inlet 110 and embedding the device inside the sonic logging pipe. Simultaneously with lowering the pipe, the water source is turned on. Water flows through the outlet 120, driving the propeller blade 232 to rotate, which in turn causes the rotating cleaning component 200 to rotate relative to the cylinder 100. Therefore, the water discharged through the outlet pipe 220 forms a spiral shape, thoroughly flushing the inner wall of the sonic logging pipe. Furthermore, driven by the rotating cleaning component 200, the scraper 240 scrapes and washes the moist inner wall. This design removes blockages adhering to the inner wall of the sonic logging pipe, reducing the impact of these blockages on pile quality testing. In addition, as the clearing device penetrates deeper, water flowing through the guide hole 141 to the remaining space and finally overflowing through the drain outlet 150 can perform a secondary flushing of the inner wall of the sonic logging pipe, achieving a comprehensive cleaning of its inner wall.

[0038] This embodiment discloses a pile foundation sonic logging pipe clearing device, which differs from the previous embodiment only in the following way: In this embodiment, a motor connected to the rotating component 231 is also provided inside the fixed shaft 130. By providing a motor, stronger power support can be provided in the event of severe concrete blockage, ensuring thorough removal of the blockage, thereby comprehensively improving the applicability and working efficiency of the pile foundation sonic logging pipe clearing device.
