Description

Technical Field

[0001] The present invention relates to the technical field of geophysical exploration, and specifically to a denoising device for geophysical signals and a denoising method thereof. Background Art

[0002] Engineering geophysical exploration, abbreviated as engineering geophysics, has a detection target of underground rock and soil layers or building structures. After loading a natural or artificial physical field on the detection target, its changes are observed through instruments to determine the spatial range (size, shape, distribution) of hidden targets and measure the physical parameters of the target body, achieving a physical exploration method for solving geological problems. At the present stage, the technical means of engineering geophysics mainly include elastic wave methods, electromagnetic wave methods, etc.; in the processing of engineering geophysical signals, suppressing the noise in the collected signals is particularly important; a denoising device is a device dedicated to denoising the received signals. There are several types of signal denoising devices currently applied on the market, such as HD3 oscilloscopes, noise spectrum analyzers, filters, and noise eliminators, which are used for denoising different detection signals. For example, the HD3 oscilloscope is biased towards denoising with an ultra-low background noise of 50 μVRMS in a 1 GHz bandwidth to obtain more accurate and reliable data. Another example is that the noise spectrum analyzer is biased towards signal spectrum analysis and identification for denoising, and the filter is biased towards the function of common ground interference isolation and has a better bias effect in eliminating the current sound and noise in audio signals. According to the types of different geophysical signal acquisitions, corresponding types of denoising devices are required;

[0003] The above four commonly used existing denoising devices are often set and carried separately for application, and have the following deficiencies when in use: 1. Since there are multiple types of geophysical signal acquisitions, different types of acquisition methods require different denoising devices. In multi-type signal acquisition work, multiple denoising devices need to be carried separately for on-site flexible selection and application. There is a lack of a structure that integrates multiple denoising devices for safe, convenient, and flexible application, and the separate carrying method has unsatisfactory usability; 2. It cannot be integrally increased in height for support and environmentally friendly powered during use. It is necessary to separately carry a bracket for support work. Although existing denoising devices are equipped with solar panels for power supply during long-term exploration work, when not in use, the solar panels are directly exposed outside and are easily damaged by accidental touch during carrying, and the safety is unsatisfactory; 3. It cannot be integrally and conveniently increased in expansion and anti-tilting support during use. When placed, the lower support area is small, which easily leads to instability and easy tilting;

[0004] In order to solve the problems that multiple denoising devices cannot be integrated for safe, convenient, and flexible application, cannot be integrally increased in height for support and environmentally friendly powered during use, and cannot be integrally and conveniently increased in expansion and anti-tilting support during use, we have therefore proposed a denoising device for geophysical signals and a denoising method thereof to solve the above problems.

[0013] Preferably, a first threaded hole threadedly connected to the first screw rod is formed in the top of the lifting plate.

[0014] Preferably, a second threaded hole threadedly connected to the corresponding second screw rod is formed in one side of the moving seat.

[0017] The present invention also provides a noise reduction method for a noise reduction device of geophysical signals, including the following steps:

[0018] S1: Drive the first screw rod to rotate by starting the small motor in the forward direction. The rotation of the first screw rod drives the lifting plate to move upward. The lifting plate drives the cover plate to move upward through two outer tubes to unseal it, and drives four noise reduction devices, namely the HD3 oscilloscope, the noise spectrum analyzer, the filter, and the noise eliminator, to move upward and out. Personnel select a suitable noise reduction device according to the use of noise reduction for denoising the received geophysical signals, achieving the effect of integrating the four noise reduction devices into one body for safe, convenient, flexible selection and application, so as to facilitate the denoising of various geophysical signals such as artificial seismic waves and noise;

[0019] S2: When the first screw rod rotates in S1, it also drives the first bevel gear to rotate. The first bevel gear drives two second screw rods to rotate in opposite directions through two second bevel gears meshing with it. The opposite rotation of the two second screw rods drives the two moving seats to move away from each other. When the two moving seats move away from each other, they drive four connecting rods to rotate away from each other through four rotating sleeves, changing their inclination state. When the connecting rods rotate, their tops gradually rise and drive the moving seats to rise through the corresponding rotating sleeves. The two moving seats drive the box-shaped support plate and the protective shell to rise upward for lifting and supporting work;

[0020] S3: When the protective shell moves upward in S2, it drives four shielding plates to move upward through eight supporting blocks. When the shielding plates move upward, they drive the corresponding two pull rods to rotate and squeeze the vertical guide plate. Under the squeezing force, the four shielding plates turn outwards synchronously and drive the four solar panels to turn outwards, achieving the effect of automatically turning out the solar panels for utilization when moving out and rising;

[0021] S4: After the solar panels turn out in S3, convert the solar energy into electrical energy and store it in the storage battery, and use the inverter to convert the direct current into alternating current to supply power to the noise reduction devices and the small motor, achieving the effect of environmentally friendly and energy-saving power supply using solar energy;

[0022] S5: When the box-shaped support plate rises in S2, it also drives the tops of four soft steel wire ropes to move upward. At this time, the four soft steel wire ropes slide outside the corresponding pulleys respectively, and pull the four loop-shaped guide plates to move outwards and expand. The four loop-shaped guide plates stretch four tension springs, and the four loop-shaped guide plates drive the four box-shaped supports to move outwards and expand, achieving the effect of automatically expanding and stabilizing the lower part and preventing tilting when moving out and rising;

[0023] S6: When the ground is uneven, personnel rotate the corresponding T-shaped screw rod to drive the corresponding rectangular seat to move up and down. The rectangular seat drives the corresponding ball to move up and down to adjust the extended support length, and uses the method that can be adjusted separately in the front, back, left, and right to facilitate the adaptation and adjustment when the ground is uneven;

[0024] S7: After use, by reversely starting the small motor, the movement direction is completely opposite to that of the above-mentioned forward start of the small motor. The lifting plate changes to move downward and drives the four noise reduction devices to be integrally and safely stored and hidden and protected inside the protective shell. The box-shaped support plate and the protective shell change to move back downward to reduce the overall height. When the protective shell moves downward, it drives the four shielding plates to move downward. At this time, when the corresponding shielding plate moves downward, the traction rod forms a pull on it. Under the pulling action, the four shielding plates rotate upward and close, and drive the four solar panels to rotate and be respectively hidden and stored in the corresponding storage holes. When the box-shaped support plate moves downward, it also relaxes the tension on the four soft steel wire ropes, and uses the multiple tension springs in the stretched state to drive the multiple return guide plates to contract inward and move back, thereby driving the four box-shaped supports to contract inward, reducing the occupied area at the bottom, facilitating the carrying work, and achieving the effects of safely storing and hiding and protecting the noise reduction devices and the solar panels integrally with a single drive after use, reducing the overall height, and reducing the occupied space at the lower part. Moreover, the method of achieving the above-mentioned multiple functions with a single drive has a good energy-saving effect.

The two opposite tension rods 603 are symmetrically arranged. The arranged vertical guide plates 6, support blocks 601, shielding plates 602, and tension rods 603 cooperate. When the protective shell 1 and the box-shaped support plate 102 move upward, the four shielding plates 602 are driven to move upward by the eight support blocks 601. When the shielding plates 602 move upward, the corresponding two tension rods 603 rotate and press the vertical guide plates 6. Under the extrusion force, the four shielding plates 602 turn outward synchronously and drive the four solar panels 604 to turn outwards. The four solar panels 604 are used to convert solar energy into electrical energy and store it in the storage battery 605, and the inverter 606 is used to convert direct current into alternating current for power supply work.

Soft steel wire ropes 703 are fixedly connected to the inner walls of the four rectangular guide plates 701 on the adjacent sides. One end of the soft steel wire rope 703 bypasses the bottom of the corresponding pulley 702 and movably passes through to the inside of the box-shaped support plate 102. An activity perforation for the corresponding soft steel wire rope 703 to movably pass through is opened on the inner wall of the top of the rectangular through hole 7. One end of the soft steel wire rope 703 is fixedly connected to the inner wall of the top of the box-shaped support plate 102. L-shaped plates 704 are fixedly connected to the inner walls of the four sides of the rectangular bottom plate 3.

Box-shaped supports 706 with open bottoms are fixedly connected to the mutually repulsive sides of the four rectangular guide plates 701. A rectangular seat 707 is slidably sleeved in the box-shaped support 706. Three balls 708 are movably embedded at the bottom of the rectangular seat 707. A T-shaped screw 709 is rotatably embedded at the top of the box-shaped support 706. A circular hole is opened on the inner wall of the top of the box-shaped support 706, and a fourth bearing is fixedly sleeved in the circular hole. The inner ring of the fourth bearing is fixedly sleeved on the outer side of the T-shaped screw 709, achieving the effect of rotatably installing the T-shaped screw 709. The rectangular seat 707 is threadedly sleeved on the corresponding T-shaped screw 709.

When the box-shaped support plate 102 is lifted, the top ends of the four soft steel wire ropes 703 are also driven to move upward. At this time, the four soft steel wire ropes 703 slide on the outer sides of the corresponding pulleys 702 respectively, and pull the four rectangular guide plates 701 to expand and move outward. The four rectangular guide plates 701 stretch the multiple tension springs 705, and the four rectangular guide plates 701 drive the four box-shaped supports 706 to expand and move outward, realizing the effect of automatically expanding and stabilizing the support of the lower part integrally when moving out and lifting, increasing the lower support area and reducing the tipping risk; when the ground is uneven, the operator can rotate the corresponding T-shaped screw 709 to drive the corresponding rectangular seat 707 to move up and down, and the rectangular seat 707 drives the corresponding balls 708 to move up and down to adjust the extended support length.

The two second screw rods 501 rotating in opposite directions drive the two moving seats 504 to move away from each other. When the two moving seats 504 move away from each other, they drive the four connecting rods 506 to rotate away from each other through four rotating sleeves 505, changing their inclination states. When the connecting rods 506 rotate, their tops gradually rise and drive the moving seats 504 to rise through the corresponding rotating sleeves 505. The two moving seats 504 drive the box-shaped support plate 102 and the protective shell 1 to rise upward through two T-shaped guide rails 507 to perform the integral lifting and supporting work during use. The personnel can use it more conveniently through the lifting and supporting.

The inverter 606 is used to convert direct current into alternating current to supply power to the noise reduction device and the small motor 104, achieving the effect of environmentally friendly and energy-saving power supply using solar energy;

[0065] S5: When the box-shaped support plate 102 in S2 rises, it also drives the tops of the four soft steel wire ropes 703 to move upward.

Under the pulling action, the four shielding plates 602 rotate upward and close, and drive the four solar panels 604 to rotate and be respectively hidden and stored in the corresponding storage holes 101. When the box-shaped support plate 102 moves downward, it also relaxes the tension on the four soft steel wire ropes 703, and uses the multiple tension springs 705 in the stretched state to drive the multiple return guide plates 701 to contract inward and move back, thereby driving the four box-shaped supports 706 to contract inward, reducing the bottom occupied area, facilitating the carrying work, and achieving the effects of single-drive integration for safely storing and hiding and protecting the noise reduction devices and the solar panels 604, reducing the overall height and shrinking the lower occupied space after use, avoiding the phenomenon that the noise reduction devices and the solar panels 604 are exposed and damaged by accidental collision during carrying, improving the carrying safety, and by integrating multiple noise reduction devices in one body, avoiding the phenomenon of separate storage and carrying respectively, improving the use convenience, and the way of single-drive integration to achieve the above-mentioned multiple functions has a good energy-saving effect, without the need to separately set up power driving devices for multiple functions, and also has a high effect of easy use, facilitating the simple operation of personnel.

The four outward-turned guard plates (602) drive the four solar panels (604) to flip outward for use; S4: After the solar panel (604) described in S3 is turned out, the solar energy is converted into electrical energy and stored in the storage battery (605), and the inverter (606) is used to convert the direct current into alternating current to power the noise removal device and the small motor (104); S5: When the box-shaped support plate (102) described in S2 is raised, the four soft steel wire ropes (703) pull the four return guide plates (701) to move outwards, and the multiple tension springs (705) are stretched. The four return guide plates (701) drive the four box-shaped supports (706) to move outwards to expand and stabilize the support and prevent tilting at the lower part; S6: A person rotates the corresponding T-shaped screw (709) to drive the corresponding rectangular seat (707) to move up and down, and the rectangular seat (707) drives the corresponding ball (708) to move up and down to adjust the extended support length to adapt to the uneven ground; S7: After use, the small motor (104) is started in reverse to perform opposite movement, the lifting plate (2) is transformed to move downward and drive the four noise reduction devices to be safely stored and hidden in the protective shell (1), the four guard plates (602) are transformed to rotate upward and drive the four solar panels (604) to rotate and be hidden in the corresponding storage holes (101), the box-shaped support plate (102) is transformed to move downward and release the tension on the four soft steel wire ropes (703), and the multiple tension springs (705) in the stretched state drive the four box-shaped supports (706) to retract inward through the multiple circular guide plates (701) to release the expansion state.
