[0001] The present invention relates to the technical field of distance measurement of internal components of equipment, and in particular to a distance measurement device and a distance measurement method of internal components of equipment. Background Art

[0002] For equipment with multiple internal components, the reasonable positioning of the internal component sizes and the detection of the spacing between components, such as the flange and the internal component to be tested, are crucial to the quality of the equipment product and can provide a basis for the subsequent installation of various systems in the equipment.

[0003] At present, the industry uses the method of making assembly tools for measurement. For large diameters (some equipment even reaches 5 meters) and high heights (some equipment even reaches more than 30 meters), the assembly tools need to be made of thicker materials to prevent deformation, which leads to excessive weight of the assembly tools, increasing the difficulty of subsequent installation and increasing labor and equipment costs. At the same time, due to the large diameter of the assembly tools, the safety of personnel climbing cannot be guaranteed when installing the assembly tools.

[0004] Therefore, there is an urgent need for a spacing measurement device and a spacing measurement method for internal components of an equipment to solve the above problems. Summary of the invention

[0008] A wire structure, the wire structure is reciprocatedly inserted into a plurality of flange holes of the flange and forms a supporting mesh structure in the middle hole of the flange;

[0009] A detection plate, the detection plate is arranged on the supporting net structure;

[0010] A distance meter is provided on the internal component to be measured, and can measure the distance between the internal component to be measured and the detection plate.

[0016] As a preferred solution of the spacing measurement device provided by the present invention, the thickness of the detection plate is 0.2mm-0.5mm.

[0017] As a preferred solution of the spacing measurement device provided by the present invention, the wire structure is a nylon wire structure.

[0018] According to another aspect of the present invention, an object is to provide a method for measuring the spacing between components in a device, wherein the method for measuring the spacing between components in a device is based on the spacing measuring device as described in any of the above schemes, and measures the spacing between the flange in the device and the internal component to be measured. The method for measuring the spacing between components in the device comprises:

[0019] S10, inserting the wire structure into the flange to form the supporting net structure;

[0020] S20, installing the detection plate on a side of the support network structure facing the internal component to be detected;

[0024] S11, the wire structure penetrates into one of the flange holes from the side of the flange facing the internal component to be measured, and passes out from the side of the flange hole away from the internal component to be measured and extends to another flange hole opposite to the flange in the diameter direction, and penetrates from the side away from the internal component to be measured, and then passes out from the side facing the internal component to be measured;

[0045] Figure 1 A schematic diagram showing the assembly of the support net structure and the detection plate on the flange provided by an embodiment of the present invention; Figure 2 The figure shows a schematic diagram of the installation of the support net structure provided by the embodiment of the present invention on the flange. Figure 1 and Figure 2 This embodiment provides a distance measurement device, which includes a wire structure, a detection board 200 and a distance meter (not shown).

[0046] Specifically, the wire structure is reciprocatedly penetrated in the multiple flange holes 11 of the flange 10, and a support mesh structure 100 is formed in the middle hole 12 of the flange 10. The detection plate 200 is arranged on the support mesh structure 100. That is to say, the support mesh structure 100 can extend the plane where the flange 10 is located at the position of the middle hole 12, and provide an installation position for the detection plate 200; the detection plate 200 can provide a distance measurement object for the rangefinder. The rangefinder is arranged on the internal component to be measured (not shown in the figure), and can measure the distance between the internal component to be measured and the detection plate 200. Since the detection plate 200 is placed on the support mesh structure 100, it is considered that the distance between the detection plate 200 and the internal component to be measured is within the error range, that is, the distance between the internal component to be measured and the plane where the flange 10 is located, thereby realizing the detection of the distance between the internal component to be measured and the flange, simplifying the distance measurement method between the internal components of the long-distance and large-caliber products, improving the measurement efficiency, and reducing the measurement cost. In this embodiment, the internal component to be tested may specifically be a tapered disk disposed in a rotor sail having a longer length and a larger diameter, and the flange 10 is also disposed in the rotor sail.

[0047] More specifically, the support mesh structure 100 is radially arranged with the center of the middle hole 12 as the center. Through the above arrangement, the flatness and support performance of the support mesh structure 100 can be improved to ensure the support effect on the detection board 200.

[0048] Preferably, the support mesh structure 100 forms a multi-layer structure in the vertical direction. Through the above arrangement, the strength of the support mesh structure 100 can be further enhanced, the horizontality of the detection board 200 placed thereon can be ensured, and the accuracy of the subsequent measurement of the spacing between the internal component to be tested and the detection board 200 can be ensured.

[0049] More specifically, the line structure is a nylon line structure. In this embodiment, the line structure can be specifically a fishing line, which has the characteristics of small line diameter and high strength, and can provide reliable support for the detection board 200.

[0050] More specifically, the detection plate 200 is bonded to the support mesh structure 100. Through the above arrangement, the stability of the detection plate 200 relative to the flange 10 can be ensured, thereby ensuring the accuracy of the measurement of the distance between the internal component to be tested and the detection plate 200.

[0051] Optionally, the detection plate 200 is a rectangular plate structure or a circular plate structure. It is sufficient to ensure that the detection plate 200 can be accommodated in the middle hole 12 and can face the rangefinder at the bottom of the internal component to be measured. In this embodiment, the inner diameter of the middle hole 12 is 4560 mm, and the detection plate 200 is specifically rectangular with a size of 300 mm×500 mm.

[0052] Optionally, the thickness of the detection plate 200 is 0.2 mm to 0.5 mm. In this embodiment, the thickness of the detection plate 200 is preferably 3 mm. The detection plate 200 can be made of ABS (Acrylonitrile-butdiene-styrene) board, which has excellent mechanical properties of toughness, hardness and rigidity.

[0053] More specifically, the rangefinder can emit a distance-measuring laser toward the detection board 200, and can receive the distance-measuring laser reflected from the detection board 200. That is, in this embodiment, the rangefinder is specifically a laser rangefinder.

[0054] This embodiment also provides a method for measuring the spacing between components in a device. The method for measuring the spacing between components in a device is specifically based on the spacing measurement device provided in this embodiment, and measures the spacing between the flange 10 in the device and the internal component to be measured. In this embodiment, the device can specifically be a rotor sail with a longer length and a larger diameter. The method for measuring the spacing between components in the device includes:

[0055] Step S10 , inserting the wire structure into the flange 10 to form the supporting mesh structure 100 .

[0056] Specifically, Figure 3 The schematic diagram of the process of threading the wire structure provided by the embodiment of the present invention on the flange is shown. Figure 3 , the above step S10 specifically includes:

[0057] Step S11, the wire structure penetrates into one of the flange holes 11 from the side of the flange 10 toward the internal component to be measured, and passes out from the side of the flange hole 11 away from the internal component to be measured and extends to another flange hole 11 opposite in the diameter direction of the flange 10, and penetrates from the side away from the internal component to be measured, and then passes out from the side toward the internal component to be measured.

[0058] Step S12, after at least one flange hole 11 is spaced apart along the circumference of the flange 10, repeat step S11.

[0059] S13, repeating step S12 multiple times along the circumference of the flange 10, so that the support net structure 100 can be formed within the range of the middle hole 12. The support net structure 100 is flush with the lower end surface of the flange 10 away from the internal component to be tested.

[0060] Step S20: Install the detection plate 200 on the side of the support network structure 100 facing the internal component to be detected by bonding or other methods.

[0061] Step S30: Install the distance meter on the side of the internal component to be tested that faces the detection board 200.

[0062] Step S40, measure the distance between the internal component to be tested and the detection board 200 for multiple times, and take the average value as the distance value between the internal component to be tested and the detection board 200. In this embodiment, the distance measurement process between the internal component to be tested and the detection board 200 is specifically performed five times, thereby improving the measurement accuracy.
