Description

Technical Field

[0001] The utility model belongs to the technical field of marine engineering, and in particular relates to a seabed type static penetration probe rod correction device and static penetration equipment. Background Art

[0002] Static penetration sounding is currently an important survey method for marine engineering in near-shore shallow waters. In response to the needs of offshore wind power foundation surveys, deep static penetration sounding can be carried out in water depths of less than 30m and exploration depths of less than 120m. The probe rod is a penetration push rod used on a seabed-type sounding device. When detecting the soil or liquid at a certain location, the probe rod with the sounding probe is pressed into the test soil layer or liquid for detection. The penetration resistance of the soil or liquid is measured by the measurement system, and some basic physical and mechanical properties of the soil or liquid can be determined. The probe rod is one of the indispensable components of the sounding equipment.

[0003] The inventors have found that when the probe rod of the penetration equipment is inserted into the soil or penetrates the water, it is easy to tilt. Especially when the penetration depth is large, the penetration path cannot be guaranteed to be vertical, thereby affecting the data. Utility Model Content

DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0028] Example 1:

[0029] As described in the background art, when the probe rod of the penetration equipment is inserted into the soil or penetrates the water, it is easy to tilt. Especially when the penetration depth is large, the penetration path cannot be guaranteed to be vertical, thereby affecting the data.

[0030] In response to the above problems, Figure 1 As described above, this embodiment provides a seabed type static cone penetration probe correction device, comprising a rotating drum 1, a telescopic mechanism 2 provided on the side of the rotating drum 1, and a driving mechanism 3 connected to the rotating drum 1;

[0031] A side hole 102 is opened on the side of the rotating drum 1 , and a pressure head 202 corresponding to the side hole 102 is provided at the telescopic end of the telescopic mechanism 2 .

[0032] It can be understood that the probe rod passes through the rotating drum 1. When the probe rod is inserted into the soil or penetrates the water, the pressure head 202 presses the probe rod under the action of the telescopic mechanism 2, and the rotating drum 1 rotates under the action of the driving mechanism 3. By rotating and squeezing, the deviation of the probe rod is corrected to ensure that the probe rod is in a vertical state, thereby ensuring the vertical penetration of the probe rod.

[0033] like Figure 1 As shown, the drum 1 includes a through hole 101 formed in the axial direction of the drum 1 and a side hole 102 formed in the side wall; the through hole 101 is used to pass through the probe, and the side hole 102 is used to pass through the pressure head 202. The drum 1 can optionally be a metal tube. It is understood that the inner diameter of the drum 1 is larger than the diameter of the probe.

[0034] like Figure 1 As shown, in some embodiments, a telescopic mechanism 2 is provided on each side of the rotating drum 1, and a side hole 201 is provided on each side of the rotating drum 1, thereby improving the correction effect. Of course, in other embodiments, multiple telescopic mechanisms 2 and multiple side holes 201 may be provided along the circumference of the rotating drum 1 to further improve the correction effect.

[0035] like Figure 1 and Figure 2 As shown, a sealing mechanism 5 is provided on the outside of the drum 1, and the sealing mechanism includes an upper sealing cover 401 and a lower sealing cover 402 provided on the outside of the drum 1 via a rotating connector 4. The upper sealing cover 401 and the lower sealing cover 402 can be made of metal.

[0036] like Figure 1 As shown, the lower sealing cover 401 is provided with a cavity for accommodating the telescopic mechanism 2, and a side sealing cover 403 is provided outside the cavity by means of bolts or the like. The upper sealing cover 401 and the lower sealing cover 402 can be connected by means of bolts or the like.

[0037] like Figure 1 As shown, optionally, the cavity on the lower sealing cover 401 is a circular hole, and the telescopic part of the telescopic mechanism 2 is a piston-type telescopic rod with movement and sealing functions. The non-moving part of the telescopic mechanism 2 can be fixed to the rotating drum by bolts or other connection methods.

[0038] like Figure 1 As shown, a first sealing ring 6 is disposed between the upper sealing cover 401 and the rotating drum 1, a second sealing ring 7 is disposed between the upper sealing cover 401 and the lower sealing cover 402, and a third sealing ring 8 is disposed between the lower sealing cover 402 and the rotating drum 1. It will be appreciated that the first sealing ring 6 and the second sealing ring 7 are rotating seals. The upper sealing cover 401 and the lower sealing cover 402 function as seals, providing a sealed protection for the entire device and enabling underwater operation.

[0039] like Figure 1 and Figure 3 As shown, the rotating connection member 5 may optionally be a bearing.

[0040] like Figure 2 and Figure 3As shown, the drive mechanism 3 includes a frame 301, a motor 302 and a rotating disk 303 mounted on the frame 301 via bolts or other connection methods; the rotating disk 303 is connected to the rotating drum 1 via bolts or other connection methods. Optionally, a hole coaxial with the through hole 101 is defined in the center of the rotating disk 303; a first gear can be provided on the rotating disk 303, and a second gear meshing with the first gear can be provided on the output shaft of the motor 302, so that the motor 302 can drive the rotating disk 303 to rotate, thereby driving the rotating drum 1 to rotate.

[0041] The telescopic member 201 may be an electric telescopic rod, a pneumatic telescopic rod or an oil cylinder. Figure 4 As shown, the oil cylinder 2015 is optionally connected to a hydraulic pump 2011 via a reversing valve 2012, and is also connected to a hydraulic motor 2014 via a safety valve 2013. The reversing valve 2012 can be a three-position, four-way reversing valve. Alternatively, hydraulic oil passes through the reversing valve and hydraulic pump 2015, etc., and enters the oil cylinder 2015 from a pre-set oil inlet at the top of the device. It then reaches the bottom of the oil cylinder 2015, pushing the oil cylinder 2015 to clamp the probe rod. At an oil pressure of 15 MPa, the clamping force of the oil cylinder 2015 can reach 40 kN.

[0042] The motor 302 can also use a hydraulic motor 2014 equipped with a reducer to reach the set value of the safety valve 2013. The hydraulic oil reaches the hydraulic motor 2014 through the safety valve 2013. The hydraulic motor 2014 drives the reducer to rotate, thereby driving the rotating disk 303 to rotate, which can ensure that the hydraulic motor rotates after clamping to avoid idling.

[0044] This embodiment provides a static penetration test equipment, which adopts the seabed type static penetration test rod correction device as described in Example 1; the other parts of the static penetration test equipment can be realized by conventional technology and will not be described in detail here.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
