Description

Technical Field

[0001] The invention relates to the technical field of offshore transformer performance detection, and in particular to an offshore transformer pressure resistance performance evaluation device based on laser induced breakdown spectroscopy. Background Art

[0002] Offshore transformers are commonly used in offshore wind power generation, offshore oil and gas platforms, and offshore renewable energy generation. In offshore wind farms, they boost the medium-voltage electricity (usually 33kV or 66kV) generated by wind turbines to high voltage (such as 220kV or higher) for efficient transmission to the land power grid via submarine cables. On offshore oil and gas platforms, transformers are used to provide a stable power supply for platform equipment to support drilling, mining, and production operations. In addition, they are also used for power conversion and transmission in ocean wave or tidal power generation systems.

[0003] However, in offshore environments, transformers are often affected by corrosive factors such as high humidity and high salinity, and their surface materials are prone to corrosion. This corrosion not only reduces the insulation performance of the transformer, but also has a significant impact on its pressure resistance performance, thereby threatening the safety of equipment operation. However, most existing evaluation methods are based on the detection of the physical state of the material surface, and lack quantitative judgment on the attenuation of its overall pressure resistance performance. Summary of the invention

[0004] In order to overcome the deficiencies in the prior art, the present invention provides an offshore transformer pressure resistance performance evaluation device based on laser induced breakdown spectroscopy, which has the advantages of faster, more convenient and more comprehensive evaluation.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] An offshore transformer pressure resistance performance evaluation device based on laser induced breakdown spectroscopy comprises a main control test system and a scanning detector; the scanning detector comprises a probe and a probe driving assembly; the probe driving assembly is used to drive the probe to move in a plane parallel to the vertical surface of the offshore transformer; the main control test system is used to emit laser and focus on the vertical surface of the offshore transformer through the probe to generate plasma, and the plasma enters the main control test system through the probe for spectral analysis; the main control test system is used to control the probe driving assembly.

[0007] By adopting the above technical solution, the main control test system generates laser and irradiates the vertical surface of the offshore transformer through a probe. The laser irradiated on the vertical surface of the offshore transformer generates plasma. The plasma enters the main control test system through the probe for spectral analysis, mainly targeting the characteristic spectral lines of chlorine (such as 837.6nm and 877.8nm) and calculating the chlorine content according to the spectral line intensity. By fitting the experimental data, the relationship between the chlorine concentration and the pressure resistance performance (such as tensile strength, compressive strength, etc.) is determined, so as to evaluate the influence of different chlorine contents on the pressure resistance performance. At the same time, the main control test system controls the probe drive assembly to drive the probe to move in a plane parallel to the vertical surface of the offshore transformer, so as to perform a complete evaluation of the entire vertical surface of the offshore transformer. The non-contact and rapid detection during the entire evaluation process avoids the need for sample preparation in traditional methods; multi-point or full-area scanning can be achieved to fully grasp the degree of corrosion on the transformer surface; through the quantitative relationship between the chlorine content and the pressure resistance performance, a more scientific pressure resistance performance evaluation method is provided.

[0008] Optionally, the main control test system includes a computer, a nanosecond laser and a spectrometer; the nanosecond laser is used to emit laser; the spectrometer is used to perform spectral analysis on plasma; the computer is used to control the nanosecond laser and the probe drive assembly and receive spectral analysis data.

[0009] By adopting the above technical solution, the computer controls the nanosecond laser to generate laser, and then the computer controls the spectrometer to perform spectral analysis on the generated plasma, and finally the computer displays the relevant evaluation information, so that the whole evaluation process is more convenient.

[0010] Optionally, the scanning detector also includes a position adjustment component; the position adjustment component includes a support base and a support plate; the upper end surface of the support base is perpendicular to the support plate; a fixed support member is provided at one end of the bottom surface of the support base, and an adjustment member is telescopically provided at the other end; the adjustment member is used to adjust the inclination angle of the support base; the probe drive assembly is provided on the upper end surface of the support base; the direction of the laser emitted by the probe is perpendicular to the support plate.

[0011] By adopting the above technical solution, the inclination angle of the supporting base can be adjusted through the adjusting member, so that the abutment plate is completely abutted against the vertical surface of the offshore transformer, so that the direction of the laser emitted by the probe is perpendicular to the vertical surface of the offshore transformer, so that the plasma generated is more easily received by the probe, which is beneficial to improving the efficiency of the evaluation.

[0012] Optionally, the support base includes a main base and an intermediate support base; the main base and the intermediate support base are arranged to slide relative to each other and their relative positions are adjustable; the probe drive assembly is arranged on the upper end surface of the main base; and the abutment plate is arranged at one end of the main base away from the main base.

[0013] By adopting the above technical solution, the relative positions of the main base and the intermediate support base are adjusted to change the distance between the probe and the vertical surface of the offshore transformer, so as to meet the stroke required for normal operation of the laser, which is conducive to improving the work efficiency of the evaluation.

[0014] Optionally, a spacing scale is provided on the intermediate support seat; the spacing scale indicates the spacing between the probe and a vertical end surface of the abutment plate away from the probe.

[0015] By adopting the above technical solution, the spacing scale on the intermediate support seat can clearly know the spacing between the probe and the vertical surface of the offshore transformer, which is conducive to adjustment.

[0016] Optionally, the adjusting member includes a pair of universal wheels; the universal wheels are equipped with brakes.

[0017] By adopting the above technical solution, a pair of universal wheels facilitates the movement of the scanning detector, and the universal wheel with brakes can complete the restriction of the universal wheel when reaching the appropriate position, thereby reducing the possibility of accidental movement of the scanning detector.

[0018] Optionally, a hidden receiving groove for receiving the abutment plate is provided on the support base.

[0019] By adopting the above technical solution, when not being evaluated, the abutment plate can be stored in the hidden storage groove, thus avoiding accidental damage to the abutment plate and affecting subsequent use effects.

[0020] Optionally, a lifting handle is provided at the upper end of the abutment plate.

[0021] By adopting the above technical solution, the presence of the lifting handle is beneficial to the operation of the abutment plate.

[0022] Optionally, a plurality of telescopic grooves distributed in the vertical direction are arranged on the vertical end surface of the abutment plate away from the probe; a horizontal pressure strip is elastically arranged in the telescopic groove; and a pressure sensor is arranged at the bottom of the telescopic groove.

[0023] By adopting the above technical solution, when the abutment plate is close to the vertical surface of the offshore transformer, all horizontal pressure strips will be subjected to pressure, thereby abutting against the pressure sensor. When the abutment plate and the vertical surface of the offshore transformer are inclined, pressure sensors at different positions will obtain different pressure values; when the pressure values ​​obtained by all pressure sensors are the same, the abutment plate and the vertical surface of the offshore transformer are parallel to each other, which is more reliable and accurate than observation with the naked eye.

[0024] Optionally, a plurality of the pressure sensors are arranged in the same expansion slot; the pressure sensors are evenly distributed along the horizontal length direction of the expansion slot.

[0025] By adopting the above technical solution, a plurality of pressure sensors are arranged in the same expansion slot, which can avoid the situation where the abutment plate and the vertical surface of the offshore transformer form an angle in the horizontal plane.

The laser irradiated on the vertical surface of the offshore transformer 3 generates plasma. The plasma enters the main control test system 1 through the probe 205 for spectral analysis, mainly for the characteristic spectral lines of the chlorine element (e.g., 837.6nm and 877.8nm) and calculates the chlorine content according to the spectral line intensity.

At the same time, the main control test system 1 controls the probe drive assembly to drive the probe 205 to move in the vertical and horizontal directions, that is, to move in a plane parallel to the vertical surface of the offshore transformer 3, so as to perform a complete evaluation of the entire vertical surface of the offshore transformer 3.

[0044] Embodiment 2: The difference between Embodiment 2 and Embodiment 1 is: Figure 3 In order to make the plasma generated by the laser irradiating the vertical surface of the offshore transformer 3 better received by the probe 205, the laser emitted by the probe 205 is preferably perpendicular to the vertical surface of the offshore transformer 3. In order to achieve this goal, the scanning detector 2 also includes a position adjustment component 201 located at the bottom of the driving support seat.

[0045] refer to Figure 5 , the position adjustment component 201 includes a support base and a support plate 208, and the support base includes a main base 209 and an intermediate support base 207; the relative position of the main base 209 and the intermediate support base 207 is adjustable, and the support plate 208 is vertically telescopically arranged at the end of the intermediate support base 207 away from the main base 209; the upper end surface of the main base 209 and the support plate 208 are perpendicular to each other; the driving support base is fixed on the upper end surface of the main base 209 so that the laser emitted by the probe 205 on the driving support base is perpendicular to the support plate 208, so that the emission direction of the probe 205 can be controlled by judging the contact state of the support plate 208 with the vertical surface of the offshore transformer 3. In order to achieve the contact between the support plate 208 and the vertical surface of the offshore transformer 3, a fixed support member 2073 is fixed at the bottom of the end of the intermediate support base 207 away from the main base 209; an adjusting member is telescopically arranged at the end of the bottom surface of the main base 209 away from the intermediate support base 207. In order to better control the tilt angle of the position adjustment assembly 201, the fixed support member 2073 can be a cylinder with its axial direction arranged horizontally.

[0046] refer to Figure 5The intermediate support seat 207 includes an L-shaped intermediate support body 2071; a horizontal sliding guide bar 2072 with a T-shaped cross section is formed on the horizontal portion of the intermediate support body 2071; a T-shaped horizontal sliding guide groove 2091 for the horizontal sliding guide bar 2072 to slide is formed on the bottom surface of the main base 209; in order to control the relative position of the intermediate support seat 207 and the main base 209, a horizontal limit bolt 210 is vertically screwed on the upper end surface of the main base 209; the horizontal limit bolt 210 passes through the upper side wall of the horizontal sliding guide groove 2091 and abuts against the horizontal sliding guide bar 2072. In order to clearly know the relative position of the main base 209 and the intermediate support seat 207, a spacing scale can be set on the horizontal sliding guide bar 2072. In order to be more conducive to subsequent evaluation, the spacing scale can directly indicate the spacing between the probe 205 and the vertical end surface of the abutment plate 208 away from the probe 205. In order to keep the vertical portion and the horizontal portion of the middle supporting body 2071 in a vertical state, reinforcing ribs 2074 are welded between the vertical portion and the horizontal portion of the middle supporting body 2071 .

[0047] refer to Figure 5 , an inverted T-shaped vertical expansion slot 2090 is formed at one end of the bottom surface of the main base 209 away from the intermediate support seat 207; the adjustment member includes an inverted T-shaped adjustment support seat 212 and an adjustment bolt 211 vertically slidably arranged in the vertical expansion slot 2090; a pair of universal wheels 213 are fixed to the bottom of the adjustment support seat 212; the universal wheels 213 are equipped with brakes, the adjustment bolt 211 is vertically screwed on the upper end surface of the main base 209, and the upper part of the adjustment support seat 212 is screwed on the adjustment bolt 211.

[0048] refer to Figure 5 and Figure 6The abutment plate 208 is in an inverted T-shape, and the upper end surface of the vertical portion of the middle support seat 207 is formed with an inverted T-shaped hidden storage groove 2070 for the abutment plate 208 to vertically extend and retract; vertical guide rods 2075 are fixed to the two ends of the hidden storage groove 2070; the two ends of the bottom of the abutment plate 208 are respectively vertically sleeved on a pair of vertical guide rods 2075. In order to keep the abutment plate 208 in a fully extended state, a pair of vertical end surfaces of the vertical portion of the middle support seat 207 are respectively screwed with upper limit bolts 214. When the abutment plate 208 is kept fully extended, the two upper limit bolts 214 respectively abut against the two end surfaces of the lower portion of the abutment plate 208. In order to keep the abutment plate 208 in the stowed state, a pair of vertical end surfaces of the vertical portion of the middle support seat 207 are respectively screwed with lower limit bolts 215. When the abutment plate 208 is in the stowed state, the two lower limit bolts 215 respectively abut against the two end surfaces of the lower portion of the abutment plate 208. In order to facilitate the extension of the abutment plate 208, a lifting handle 2081 is fixed to the upper end of the abutment plate 208.

[0049] The working principle of the second embodiment: when working, first make the abutment plate 208 close to the vertical surface of the offshore transformer 3, and then adjust the support seat 212 to vertically extend and retract by rotating the adjusting bolt 211, until it is observed that the abutment plate 208 is in contact with the vertical surface of the offshore transformer 3. At this time, the brake of the universal wheel 213 can be operated to make the universal wheel 213 unable to rotate, so that the scanning detector 2 will not move accidentally, ensuring the stability of the subsequent evaluation state.

[0050] Embodiment 3: The difference between Embodiment 3 and Embodiment 2 is that: in order to better judge the contact state between the abutment plate 208 and the vertical surface of the offshore transformer 3, refer to Figure 7 , a plurality of telescopic grooves 2080 distributed in the vertical direction are formed on the vertical end surface of the abutment plate 208 away from the probe 205; a horizontal pressure strip 223 is elastically arranged in the telescopic groove 2080, that is, a compression spring is fixed between the horizontal pressure strip 223 and the bottom surface of the telescopic groove 2080, and the compression spring provides elastic force for the horizontal pressure strip 223 to move outward; a pressure sensor 222 is arranged at the bottom of the telescopic groove 2080. The pressure sensor 222 is electrically connected to the main control test system 1, but when the force values ​​detected by all the pressure sensors 222 are the same, it indicates that the abutment plate 208 is completely in contact with the vertical surface of the offshore transformer 3, and the main control test system 1 can be provided with a reminder module to remind the operator to adjust it in place. When working, the abutment plate 208 leans against the vertical surface of the offshore transformer 3, and the vertical surface of the offshore transformer 3 drives the horizontal pressure strip 223 to shrink inward and lean against the pressure sensor 222.

[0051] Of course, in order to make the monitoring of the contact between the abutment plate 208 and the vertical surface of the offshore transformer 3 more accurate, a plurality of pressure sensors 222 are arranged in the same expansion slot 2080 ; the pressure sensors 222 are evenly distributed along the horizontal length direction of the expansion slot 2080 .

[0052] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
