Detailed Description
Embodiments of the technical scheme of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present invention, and thus are merely examples, and are not intended to limit the scope of the present invention.
Referring to fig. 1, a vibration device includes a cylinder 1, a first piston mechanism 2, a second piston mechanism 3, and a fixing assembly 4.
Referring to fig. 1,2 and 3 again, the first piston mechanism 2 includes a first piston 21 slidably disposed in the cylinder 1 and a first piston rod 22 connected to the first piston 21 and extending out of the cylinder 1; the second piston mechanism 3 comprises a second piston 31 which is arranged in the cylinder body 1 in a sliding manner and a second piston rod 31 which is connected with the second piston 31 and extends to the outside of the cylinder body 1; the second piston 31 is perpendicular to the first piston 21, and the second piston 31 matches the inner diameter of the cylinder 1. Specifically, the first piston 21 is horizontally disposed in the cylinder 1, and one end thereof abuts against the inner wall of the cylinder 1, and the other end thereof can abut against the second piston 31, thereby partitioning the inner cavity of the cylinder 1 to form a first chamber; the first piston mechanism 2 moves up and down along the first chamber, which in turn causes the end of the first piston rod 22 outside the cylinder 1 to strike the ground to emit a longitudinal wave. The second piston 31 is vertically arranged in the cylinder body 1, namely, two ends of the second piston 31 are respectively abutted against the inner wall of the cylinder body 1, so that the inner cavity of the cylinder body 1 is separated to form a second chamber; the second chamber partially coincides with the first chamber and the second piston means 3 is moved left and right along the second chamber, which in turn causes the second piston 31 to vertically strike the first piston 21, causing the first piston means 2 to emit transverse waves. It will be appreciated that the second piston mechanism 3 may also be a rodless piston structure, so that the second piston 31 includes a second piston 31 slidably disposed in the cylinder 1, the second piston 31 is perpendicular to the second piston 31, and the second piston 31 matches the inner diameter of the cylinder 1.
Referring again to fig. 1, in one embodiment, the cylinder 1 is provided with a first fluid medium port 11, a second fluid medium port 12 and a third fluid medium port 13; the first fluid medium port 11 and the second fluid medium port 12 are respectively communicated with cavities on two sides of the first piston 21, and the first fluid medium port 11 and the third fluid medium port 13 are respectively communicated with cavities on two sides of the second piston 31. Specifically, the first chamber is divided into two sets of chambers (rodless chamber and rod-like chamber) by the first piston 21, and the first fluid medium port 11 and the second fluid medium port 12 communicate with the rodless chamber and the rod-like chamber of the first chamber, respectively; and the first piston 21 slides between the first fluid medium port 11 and the second fluid medium port 12. When the first piston 21 vertically abuts against the second piston 31, the two sets of cavities of the first chamber are not communicated with each other. The second chamber is divided by the second piston 31 into two sets of chambers (rodless chamber and rod-present chamber) that are not in communication with each other, wherein the first chamber is the rodless chamber of the second chamber. The third fluid medium port 13 communicates with the rod cavity of the second chamber; and the second piston 31 slides between the first piston 21 and the third fluid medium port 13. It will be appreciated that the rod cavity of the first chamber refers to the cavity provided with the first piston rod 22 and the rod cavity of the second chamber refers to the cavity provided with the second piston rod 31.
Referring to fig. 1,2 and 3 again, in one embodiment, two sides of the first piston 21 are respectively provided with a first groove 211 and a second groove 212, the first groove 211 is communicated with the first fluid medium port 11, and the second groove 212 is communicated with the second fluid medium port 12; and/or, a third groove 311 is formed on one side, close to the third fluid medium, of the second piston 31, and the third groove 311 is communicated with the third fluid medium port 13. Specifically, when the first piston 21 moves up and down in the inner cavity of the cylinder 1 and the first piston 21 moves to the position of the first fluid medium port 11, the first groove 211 communicates with the first fluid medium port 11, so that the first piston 21 does not block the first fluid medium port 11, thereby allowing the fluid medium to smoothly enter the inner cavity of the cylinder 1. The second recess 212 is the same. When the second piston 31 moves to the position of the third fluid medium port 13, the third groove 311 communicates with the third fluid medium port 13, so that the second piston 31 does not block the third fluid medium port 13, and the fluid medium can smoothly enter the inner cavity of the cylinder 1.
Referring again to fig. 1, in an embodiment, the first piston 21 is disposed on a side of the second piston 31 away from the second piston rod 31. In particular, it is convenient for the second piston 31 to vertically strike the first piston 21.
In one embodiment, the first piston rod 22 is provided at an end of the first piston 21 that can be in contact with the second piston 31. Specifically, when the second piston 31 vertically impacts the first piston 21, the side wall of the first piston rod 22 can abut against the second piston 31, thereby increasing the area of the first piston mechanism 2 impacted and reducing the impact energy loss.
Referring to fig. 1 again, the fixing assembly 4 includes a first fixing member 41 and a second fixing member 42, where the first fixing member 41 is mounted on the cylinder 1 and is used for fixing the position of the first piston 21 in the cylinder 1; the second fixing member 42 is mounted on the cylinder 1 for fixing the position of the second piston 31 in the cylinder 1 to hold the second piston 31 against the first piston 21.
In an embodiment, after the first fixing member 41 fixes the first piston 21, the first piston 21 is located at the middle of the second piston 31, and the first piston 21 and the second piston rod 31 are located on the same straight line. Specifically, when the second piston 31 vertically impacts the first piston 21, the impact force received by the first piston 21 is maximized and the energy loss is reduced because the first piston 21 and the second piston rod 31 are in the same line.
In one embodiment, the first fixing member 41 and the first piston 21 are fixed by magnetic attraction; and/or the second fixing member 42 and the second piston 31 are fixed by magnetic attraction.
In one embodiment, the first fixing member 41 and the second fixing member 42 are both electromagnets. It can be understood that the electromagnet is a non-permanent magnet, and can generate magnetic force through current, and the magnetic force disappears when the current is closed, so that the magnetic force can be easily started or eliminated, and the connection relation between the first piston mechanism 2 and the second piston mechanism 3 and the inner wall of the cylinder body 1 is conveniently changed.
Referring to fig. 1 and 4 again, a variable energy multi-wave intelligent vibroseis includes a vibration device and a power device 5 as described above; a power device 5 for supplying a fluid medium into the cylinder 1 to drive the first piston 21 or the second piston 31 to slide in the cylinder 1. Specifically, the power unit 5 may employ an electric hydraulic pump, that is, the electric hydraulic pump is respectively communicated with the first fluid medium port 11, the second fluid medium port 12 and the third fluid medium port 13 through three sets of pipes 51. Further, a first valve 52 is mounted on the pipe 51 communicating with the second fluid medium port 12, and a second valve 53 is mounted on the pipe 51 communicating with the third fluid medium port 13. The electric hydraulic pump is the prior art, so the description is not repeated.
In an embodiment, the device further comprises an operating device for controlling the power device 5 and the fixing assembly 4. The operating device is in signal connection with the power device 5 and the fixing assembly 4, such as an electrical signal. The operating device is used for controlling the speed of the fluid medium input into the cylinder body 1 by the power device 5, thereby controlling the sliding speed of the first piston mechanism 2 and the second piston mechanism 3 so as to adjust the values of longitudinal waves and transverse waves and realize energy variation. The operation device adjusts the connection relation between the first piston mechanism 2 and the second piston mechanism 3 and the inner wall of the cylinder body 1 by controlling the fixing component 4, thereby being convenient for the flexible transition of the device between longitudinal waves and transverse waves.
Specific embodiments of the invention:
longitudinal wave:
first, the first fixing member 41 and the second valve 53 are closed by the control device, and the second fixing member 42 is opened; at this time, the first piston mechanism 2 can freely slide, and the second piston mechanism 3 is fixed to the inner wall of the cylinder 1.
Next, a fluid medium is introduced into the cylinder 1 along the first fluid medium port 11 by the power unit 5: after the fluid medium enters the rodless cavity of the first chamber, it flows downward and presses the first piston 21 to slide to the bottom wall of the cylinder 1, so that the first piston rod 22 hits the ground downward to emit longitudinal waves.
Finally, fluid medium is alternately input into the cylinder body 1 along the first fluid medium port 11 and the second fluid medium port 12 through the power device 5, so that the fluid medium alternately presses the first piston 21, and then the first piston 21 slides up and down under the action of the fluid medium, so that the first piston rod 22 generates an up and down vibration effect.
Transverse wave:
First, the second fixing member 42 and the first valve 52 are closed by the control device, and the first fixing member 41 is opened; at this time, the first piston mechanism 2 is fixed to the inner wall of the cylinder 1, and the second piston mechanism 3 is free to slide.
Next, a fluid medium is introduced into the cylinder 1 along the first fluid medium port 11 by the power unit 5: after the fluid medium enters the rodless cavity of the second chamber, the fluid medium flows rightward and presses the second piston 31 to slide to the right inner wall of the cylinder body 1; and then fluid medium is input into the cylinder body 1 along the third fluid medium port 13 through the power device 5: after the fluid medium enters the rod cavity of the second chamber, the fluid medium flows leftwards and presses the second piston 31 to impact the first piston mechanism 2 along the direction perpendicular to the first piston 21, so that the first piston mechanism 2 generates the effect of horizontal vibration; at this time, if the first piston rod 22 contacts the ground, the first piston rod 22 emits a transverse wave and propagates to the underground layer.
Finally, fluid medium is alternately input into the cylinder body 1 along the first fluid medium port 11 and the third fluid medium port 13 through the power device 5, so that the fluid medium alternately presses the second piston 31, and then the second piston 31 slides left and right under the action of the fluid medium, so that the second piston 31 vertically impacts the first piston mechanism 2, and the first piston rod 22 generates a left and right vibration effect.
The above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; while the invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will appreciate that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention, and are intended to be included within the scope of the appended claims and description.
