Description

Technical Field

[0001] This invention relates to the field of marine equipment technology, and in particular to an underwater static cone penetration test device with an automatic climbing sonar. Background Technology

[0002] Pile foundations are commonly used in critical infrastructure projects such as offshore platforms and long-span bridges. Accurately estimating the bearing capacity of pile foundations involves determining the appropriate pile penetration depth, and the bearing capacity of pile foundations is crucial for ensuring the safety of offshore infrastructure. Static cone penetration testing (PCT) equipment is a commonly used in-situ testing device in geotechnical engineering investigations. PCT offers advantages such as in-situ capability, continuity, high efficiency, and high resolution. Currently, engineering exploration often utilizes marine PCT results to calculate pile foundation bearing capacity, while simultaneously employing bottom-scanning sonar or side-scan sonar mounted on ship hulls and underwater vehicles to obtain seabed soil and topographic data.

[0003] For the construction of marine pile foundations, the use of bottom-scanning sonar or side-scanning sonar on the bottom of the ship and underwater vehicles has the following disadvantages: First, the detection range is too large, and most of the detection data is noise data; second, the accuracy of the detection results is easily affected by unknown factors such as ocean currents and marine life; finally, construction personnel need to further process and match the sonar detection results with the marine static cone penetration test results, which is a complicated process.

[0004] Therefore, the development of an integrated sonar and static cone penetration test system with features such as lightweight equipment, convenient operation, simple use, accurate results, minimal impact of unknown marine factors on results, and detection results that meet construction requirements has broad application prospects. Summary of the Invention

A floating plate water inlet / outlet device 3106 is provided at the top of the floating plate 3105. The floating plate water inlet / outlet device 3106 is internally connected to the floating plate 3105. The floating plate water inlet / outlet device 3106 is provided with several second water inlets 3107 with valves.

[0046] The sonar device 32 is movably installed in the gap between the adjacent side walls of the two floating plates 3105.

[0047] The inner tube 3103 has mounting boxes 35 on both sides, which are adjacent to the floating plate 3105. The cable 2 has climbing rails 36 on both sides. The inner wall of the mounting box 35 slides along the climbing rails 36 on the cable 2. The mounting box 35 has a groove 3503 on the side wall near the cable 2 that corresponds to the climbing rail 36. The climbing rail 36 passes through the groove 3503.

[0049] The power unit 33 includes a sliding box 3301, a first hydraulic device 3302, a motor 3303, and a climbing gear 3304. Two sliding boxes 3301 are slidably mounted on the inner wall of the upper cavity 3501 away from the cable 2. Rotary shafts 3305 are rotatably connected to the upper and lower ends of the front and rear inner walls of the sliding boxes 3301. The motor 3303 is fixed to the inner wall of the sliding boxes 3301, and sprockets 3306 are mounted on the main shaft of the motor 3303 and the rotating shaft 3305. The three sprockets 3306 are arranged in a triangular pattern, and a chain 3307 is meshed on the three sprockets 3306. The rotating shaft 3305 extends out of the sliding box 3301. The first hydraulic device 3304 is fixedly connected to the climbing gear 3304. The climbing gear 3304 on the two sliding boxes 3301 are located on both sides of the climbing track 36.

The piston rod end of the first hydraulic device 3302 is provided with a first connecting block 3308 fixedly connected to the sliding box 3301. Under the pressure and pressure control of the first hydraulic device 3302, the climbing gear 3304 passes through the strip hole and bites and releases with the climbing track 36.

When the locking gears 3404 bite with the climbing rail 36, the climbing position of the sonar device 32 is locked.

[0051] The working steps of this invention are as follows:

[0052] Step 1: As Figure 7 As shown, the device is lowered by the suspension rope 102 and the cable 2. At this time, the first hydraulic device 3402 and the second hydraulic device 3502 in the automatic climbing sonar device 3 are pressed together, and the power device 33 in the automatic climbing sonar device 3 is braked. The automatic climbing sonar device 3 can be fixed on the top of the penetrating static probe device 1 during the descent process.

[0053] Step Two: As Figure 8 As shown, when the device sinks to the predetermined position, the first hydraulic device 3302 and the second hydraulic device 3402 in the automatic climbing sonar device 3 are both released, the power device 33 in the automatic climbing sonar device 3 is released from braking, and the automatic climbing sonar device 3 begins to float up along the climbing track 36 under the buoyancy of the floating lifting device 31.

[0054] Step 3: As Figure 9As shown, when the automatic climbing sonar device 3 rises close to the measurement elevation, the first hydraulic device 3302 in the power unit 33 presses the climbing gear 3304, making it in close contact with the climbing track 36. Under the action of the motor 3303, the climbing gear 3304 climbs up the climbing track 36 to the measurement elevation. Then, the second hydraulic device 3502 in the locking device 35 presses the locking gear 3404, making it lock in the climbing track 36, fixing the position of the mounting box 35, and locking the sonar device 32. The sonar device 32 detects the surrounding terrain. Then, the above steps are repeated so that the sonar device 32 automatically climbs to different elevations to conduct sonar detection according to the actual engineering needs. At the same time, the penetrating static cone penetration test device 1 conducts soil survey.

[0055] Step Four: As Figure 10 As shown, after the sonar device 32 finishes its detection, both the first hydraulic device 3302 and the second hydraulic device 3402 are released. The first water inlet 3102 and the second water inlet 3107 in the floating lifting device 31 draw in water. After the outer tube 3101 and the floating plate 3105 expel air, the automatic climbing sonar device 3 begins to sink. When it sinks close to the top elevation of the penetrating static cone penetrating device 1, the first hydraulic device 3302 is tightened again. Driven by the motor 3303, the automatic climbing sonar device 3 moves down along the climbing track 36 to the top elevation of the penetrating static cone penetrating device 1. The power device 33 brakes. At this time, the second hydraulic device 3402 is tightened again, and the automatic climbing sonar device 3 is fixed on the top of the penetrating static cone penetrating device 1. The detection ends, and the device is lifted by the hoisting rope 102.

[0056] This invention comprises a penetrating static cone penetration test (PCP) device 1, a cable 2, an automatically ascending sonar device 3, and a signal line device 4. When conducting seabed soil and topographic exploration, the entire device is lowered to the seabed. The PCP device 1 performs seabed geological surveys, while the automatically ascending sonar device 3 moves along the ascending track 36 on the cable 2 and maps the seabed topography at the corresponding height. Operators can control the automatically ascending sonar device 3 and the PCP device 1 via the signal line and signal line device 4 within the cable 2. This invention allows for easy specification of the detection range, avoids generating most noise data, and reduces the influence of unknown factors such as ocean currents and marine life during detection, resulting in high accuracy. Furthermore, this invention is highly automated, enabling simultaneous seabed soil surveying and topographic mapping without requiring personnel to match sonar and static cone penetration test results, simplifying the process and increasing efficiency.
