[0002] In the field of vibratory construction, for vibrators with bottom discharge, the depth measurement method currently used is to use an encoder to check the extended length of the crane wire rope to indirectly calculate the descent depth of the equipment.
[0003] However, the disadvantage of this method is that it cannot eliminate the errors caused by wire rope slippage, crane mast shaking and complete hook relaxation. In addition, it is necessary to install measuring devices on various crane equipment, which increases the preparation time and equipment modification process.
[0004] Based on this, the present invention is proposed. Summary of the invention
[0005] In view of the shortcomings of the prior art, the present invention provides a depth measurement method for a bottom discharge vibrator device, and the technical solution is as follows:

[0007] When the laser light source emits a laser line with a fixed angle and hits the side of the silo of the bottom discharge vibrator equipment, a horizontal laser line is generated;
[0008] The horizontal laser line is detected by a horizontal laser line position detection strip to obtain the light position h;
[0009] When the bottom discharge vibrator equipment is aligned with the pile point and the depth is 0m, the light position h corresponding to the zero point of the pile depth is set to the initial value h0;
[0010] When the bottom discharge vibrator device measures the depth, the detected light position h corresponds to h1, and the pile depth V = h0-h1;
[0011] When the position of the horizontal laser line exceeds the detection range of the horizontal laser line position detection bar, the laser light source adjustment module is triggered to adjust the position of the horizontal laser line so that the position of the horizontal laser line emitted by the laser light source falls back into the detection range of the horizontal laser line position detection bar; at the same time, the data corresponding to the pile depth V is corrected through the data update module.

[0018] The horizontal laser line position detection bar on the bottom discharge vibrator device detects the light and dark intervals of the horizontal grating strips and converts them into light and dark sequences after processing;
[0019] During the construction of the bottom discharge vibrator equipment, the detected light and dark sequence changes. The pile depth V can be obtained by multiplying the sum of the width and interval of the horizontal grating strips by the number of changes in the light and dark sequence.
[0020] As a further solution of the present invention, a method for adjusting the position of a horizontal laser line comprises the following steps:

[0023] During the construction of the bottom discharge vibrator equipment, the light and dark changes of the staggered array are detected, and the sum of the width and interval of the horizontal grating strips multiplied by the number of light and dark changes of the staggered array can be used to obtain the pile depth V.
[0024] As a further solution of the present invention, a plurality of horizontal grating strips constitute the grating, and the spacing of the grating is unequal from top to bottom;
[0025] The intervals of the gratings are set to increase gradually from top to bottom.
[0026] or,

[0053] The present invention is described in detail below in conjunction with specific embodiments. The embodiments described below are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
[0054] Example 1
[0055] The depth measurement implementation method of the present invention is implemented based on the directional performance of the laser light source and the position detection of the horizontal grating strips.
[0056] The depth measuring equipment consists of a laser light source a fixed on the ground and a horizontal laser line position detection strip b fixed on the side of the silo of the bottom discharge vibrator equipment, such as Figure 1 shown.
[0057] A laser light source a (such as a laser level) emits a laser line with a fixed angle and hits the side of the silo of the bottom discharge vibrator device; wherein, when the laser line hits the side of the silo of the bottom discharge vibrator device, a horizontal laser line is generated.
[0058] After detection by the horizontal laser line position detection strip b, the light position h is obtained.
[0059] When the bottom discharge vibrator equipment is aligned with the pile point and the depth is 0m, the operator issues a reset command; at this time, the depth is reset, and the light position h corresponding to the pile depth zero point is set to the initial value h0.
[0060] As the bottom discharge vibrator makes holes, the depth increases continuously. At this time, the corresponding value of the detected light position h decreases continuously and finally reaches h1. The pile depth V = h0-h1. Figure 2 As shown;
[0061] When the bottom discharge vibrator equipment construction reaches a certain depth, the position of the horizontal laser line will reach the upper edge of the horizontal laser line position detection bar b, exceeding the detection range; at this time, the laser light source adjustment module is triggered to adjust the laser light source a downward by a fixed distance, so that the position of the horizontal laser line emitted by the laser light source a falls back into the detection range of the horizontal laser line position detection bar b. At the same time, the data corresponding to the pile depth V is corrected through the data update module to keep the detected pile depth V correct.
[0062] Example 2
[0063] There are many ways to adjust the position of the horizontal laser line.
[0064] The first option is as follows:
[0065] The horizontal laser line position detection strip b is divided into five areas from top to bottom according to its height direction, namely, the upper area, the upper area, the middle area, the lower area, and the lower area. Figure 3 shown.
[0066] Among them, the middle area has the largest range, accounting for 80% of the total volume of the horizontal laser line position detection strip b; the upper area and the lower area are used as adjustment buffer zones, accounting for a smaller proportion, such as 15% of the total volume of the horizontal laser line position detection strip b; the upper-upper area and the lower-lower area are used as out-of-bounds judgment areas, with the smallest range, accounting for 5% of the total volume of the horizontal laser line position detection strip b.
[0067] When the position of the horizontal laser line enters the range of the upper zone, the laser light source adjustment module is triggered, and the laser light source a moves downward to move the position of the horizontal laser line downward by a fixed distance to the upper limit of the lower zone.
[0068] When the position of the horizontal laser line enters the range of the lower-lower zone, the laser light source adjustment module is triggered to move the position of the horizontal laser line upward by a fixed distance to the lower boundary of the upper zone.
[0069] The switching of the horizontal laser line position can be achieved by extinguishing laser light source a and lighting up another laser light source a, or by using one laser light source a to quickly adjust the optical path to achieve the position change of the horizontal laser line, or by mechanically rotating the laser line emission angle of laser light source a (the angle between the laser line and the horizontal plane).
[0070] The advantage of this solution is that, as long as it is ensured that no matter where the silo is located during the entire construction process, there is at least one horizontal grating strip on the horizontal laser line position detection strip b. It only requires the laser light source a to emit several fixed horizontal grating strips (the horizontal grating strip spacing is not required to be completely equal), the requirements for the laser light source a are relatively low, and the requirements for the horizontal laser line position detection strip b are also low. As long as the horizontal grating strips can be detected and the distance between the two horizontal grating strips can be determined, it is relatively economical and practical. Disadvantages: Because the interval between the horizontal grating strips is relatively large, the height of the horizontal laser line position detection strip b is required to be relatively large.
[0071] Example 3
[0072] The second option is as follows:
[0073] The laser line emitted by the laser light source a is processed into horizontal grating strips distributed along the vertical direction, and is projected onto the entire bottom discharge vibrator device along the height range of the bottom discharge vibrator device.
[0074] The horizontal laser line position detection strip b on the bottom discharge vibrator device detects the light and dark intervals of the horizontal grating strips and converts them into a light and dark sequence after processing.
[0075] During the construction of the bottom discharge vibrator equipment, as the bottom discharge vibrator equipment moves up and down, the detected light and dark sequence also changes. The sum of the width and interval of the horizontal grating strips multiplied by the amount of change in the light and dark sequence can be used to obtain the moving distance of the bottom discharge vibrator equipment, that is, the pile depth V.
[0076] For example: for a pile construction with a drilling depth of 10m, the bottom discharge vibrator equipment is 12m high, and the top of the bottom discharge vibrator equipment is equipped with a 2m horizontal grating strip. The laser light source a is 20m away from the pile position. The laser light emitted by the laser light source a passes through the beam splitter to form a horizontal grating strip distributed vertically, such as Figure 4 The horizontal grating strips shown have a width of 5 cm and a spacing of 5 cm. There are 120 horizontal grating strips distributed within a range of 12 m. As the drilling depth increases, the horizontal laser line position detection strip b moves downward with the bottom discharge vibrator device and passes through each horizontal grating strip in sequence. When 100 horizontal grating strips are passed downward, it means that the depth has dropped by (5+5)×100 cm=10 m, and the pile depth V=10 m.
[0077] The direction in which the horizontal laser line passes across the horizontal grating strips is easy to determine.
[0078] One implementation method is: the horizontal laser line position detection strip b is composed of a series of photosensitive dot arrays arranged from top to bottom. Determine the moving direction of the horizontal grating strip: when one of the photosensitive points detects a signal from bright to dark, if the upper adjacent photosensitive point is bright before the change, and the lower adjacent photosensitive point is dark, it means that the grating strip is moving up. On the contrary, if the lower adjacent photosensitive point is bright before the change, and the upper adjacent photosensitive point is dark, it means that the horizontal grating strip is moving down.
[0079] Another method: Using the covariance analysis method in statistical mathematics, the values of the photosensor array before and after the change can be analyzed to directly obtain the moving direction and distance.
[0080] The advantage of this solution is that the horizontal grating strips in the grating are equally spaced, and the moving distance of the horizontal laser line position detection strip b can be calculated by simply counting the light and dark textures. In addition, the counts can be detected at different positions to reduce the error rate. At the same time, because the horizontal grating strips in the grating are dense, the height of the horizontal laser line position detection strip b does not need to be very large.
[0081] Example 4
[0082] The third option is as follows:
[0083] Based on the second solution, the number of horizontal laser line position detection strips b is simplified to two, and the corresponding gratings are set into two staggered arrays to detect light and dark respectively. As long as the horizontal grating strips are fine enough (the number is large enough), the pile depth V can be obtained by counting the number of light and dark changes.
[0084] That is to say, during the construction of the bottom discharge vibrator equipment, the light and dark changes of the staggered array are detected, and the sum of the width and interval of the horizontal grating strips multiplied by the number of light and dark changes of the staggered array can be used to obtain the pile depth V.
[0085] This solution uses two horizontal laser line position detection strips b, which can correct errors and improve resolution.
[0086] Example 5
[0087] The fourth option is as follows:
[0088] On the basis of the second scheme, the grating (multiple horizontal grating strips constitute the grating) style is modified, and the spacing of the grating (the spacing between two adjacent horizontal grating strips) is unequal from top to bottom; for example, the spacing gradually widens, and the width of the lower horizontal grating strip is twice the width of the upper horizontal grating strip immediately adjacent. In this way, as long as the width of one of the horizontal grating strips is detected, it is possible to deduce which horizontal grating strip this is, and thus the height position h1 of the horizontal grating strip can be directly measured. Alternatively, a non-repeating coding sequence is formed by the horizontal grating strips of various widths and the spacing of the grating, so that by detecting the coding sequence, the position of this horizontal grating strip in the entire grating can be determined, and then the height position h1 of the horizontal grating strip can be determined, and the pile depth V is obtained.
[0089] Because different sequences correspond to different pile depths V, the pile depth V can be output according to the sequence.
[0090] Example 1: Figure 5 As shown, some combinations of spacing of 1 or 2 cm and horizontal grating strip width of 1 to 5 cm are formed. If the spacing width above each horizontal grating strip forms a pair of combinations with the horizontal grating strip width, the combination sequence in the figure is: (1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (2, 1), (2, 2), (2, 3), (2, 4), (2, 5).
[0091] Example 2: It does not distinguish whether it is a horizontal grating strip or a grating interval, and only considers the width of the horizontal grating strip. For example, the sequence is composed of multiple series, and the series consists of 5 elements. For example, the first five-element sequence is (1, 1, 1, 2, 1), and the second five-element sequence after one position is wrong is (1, 1, 2, 1, 3). As long as any two series in the sequence are not repeated, each position has a unique code that is different from other positions, so its position can be determined by the sequence. The elements in this series can be generated by random generation, pseudo-random number generation, or irrational number decimal generation.
[0092] For example, the first 100 digits of pi: 3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679;
[0094] The following sequence is formed, and it is arranged and compared according to the numerical value to ensure that there is no duplication:

[0101] The following sequence is formed, and it is arranged and compared according to the numerical size to determine that there is no duplication: 27182, 71828, 18281, 82818, 28182, 81828, 18284, 82845, 28459, 84590, 45904, 59045, 90452, 04523, 45235, 52353, 23536, 35360, 53602, 36028, 6028 7,02874,28747,87471,74713,47135,71352,13526,35266,52662,26624,66249,62497,24977,49775,97757,77572,75724,57247,72470,24709,47093,70936,09369,93699,36999,6 9995,99959,99595,95957,59574,95749,57496,74966,49669,96696,66967,69676,96762,67627,76277,62772,27724,77240,72407,24076,40766,07663,76630,66303,63035,303 53,03535,35354,53547,35475,54759,47594,75945,59457,94571,45713,57138,71382,13821,38217,82178,21785,17852,78525,85251,52516,25166,51664,16642,66427,64274.
[0102] This scheme has the ability to detect absolute values, while schemes 1 to 3 are relative values. If a power outage and restart occurs during the construction process, schemes 1 to 3 may lose the benchmark and cause large errors in the detection; this scheme does not detect the history and directly obtains the current detection value by reading the sequence.
[0103] Example 6
[0104] The fifth option is as follows:
[0105] Based on the second solution, two gratings of different colors (or two gratings of different modulations) are used.
[0106] The changes in the width of the horizontal grating strips are combined into combinations of different widths to construct a combination sequence, for example, (1, 2), (2, 3); these combination sequences are not repeated, and the two columns of horizontal grating strips correspond to two laser light sources a respectively. By splicing the two detected combination sequences together, a unique data pair is formed. They uniquely determine the position at this time, that is, because different data pairs correspond to different pile depths V, the pile depth V can be output according to the data pairs.
[0107] The horizontal laser line position detection strip b can be integrated by vertically continuous splicing of photodiode array devices. Alternatively, independent photosensitive components, such as photosensitive diodes, can be arranged on the board surface. Alternatively, optical fibers can be used for arrangement. The number and density of the arrangement determine the resolution of the horizontal laser line position detection strip b.
[0108] In the case where the bottom discharge vibrator device has a tendency to rotate, a plurality of horizontal laser line position detection strips b may be arranged on different sides of the bottom discharge vibrator device.
[0109] Laser light source a modulation can use an electrical signal of a certain frequency to modulate the brightness of the light source, or it can modulate the brightness of the emitted light by rotating a polarizing lens.
[0110] This solution is an upgraded version of the fourth solution. It uniquely calibrates the position by combining two columns of sequences to form a longer ordered array. It has higher resolution, a larger calibration range, and stronger error correction capability.

[0113] Figure 1 The guide rod height of the bottom discharge vibrator equipment is 25m, the height of the silo is 5m, the total height H=30m, and the maximum pile depth V can reach 23m. The laser light source a is 50m away from the pile hole horizontally. The horizontal laser line falls at a height of about 26m. The height of the horizontal laser line position detection bar b is h=5m. Six gratings distributed up and down are required to complete a pile depth. A 10-line array laser multi-line beam splitter is used, and the angle distribution of each beam ensures that the distance between each beam in the far field vertical direction is equal, such as Figure 6 shown.
[0114] In addition, it should be understood that those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
