Description

Technical Field

[0001] This utility model relates to the field of seismic exploration, specifically to an electro-hydraulic seeding device. Background Technology

[0002] Nodal geophones are geophones where all components are housed within a casing, eliminating the need for cable connections. Due to their advantages such as better adaptability to complex surface conditions, lightweight and flexible design, independence from the number of acquisition channels, ease of field use, and high construction efficiency, nodal geophones are becoming increasingly popular in geophysical acquisition applications. Currently, they are widely used in seismic exploration data acquisition.

[0003] Due to issues such as compensation claims, seismic exploration projects require winter and spring construction. In northern regions, winters are cold, and the low surface temperature causes the soil to freeze and harden, making digging difficult and preventing the geophone's tail cone from being inserted into the ground for data acquisition. Previously, winter construction and seeding relied mainly on striking the soil with a rubber mallet; however, the low winter temperatures harden and brittle the geophone's plastic casing, and prolonged striking can damage the geophone and lead to data loss.

[0004] In field construction, the installation of nodal geophones is of paramount importance for field data acquisition. Ensuring the integrity of the nodal geophones and the completeness of the data is fundamental to the survival of any geophysical surveying unit. Therefore, it is necessary to take measures to ensure the integrity of the nodal geophones during winter construction. Utility Model Content

The output end of the controller is connected to the hydraulic valve and the hydraulic pump respectively.

[0008] A further improvement of this utility model is that the input terminal of the controller is electrically connected to the position sensor, which includes a first position sensor disposed at the end of the piston rod and a second position sensor disposed at the tail cone of the node detector.

[0010] A further improvement of this invention is that the node detector is connected to the piston rod via a gasket.

[0011] A further improvement of this utility model is that the hydraulic control unit is connected to the operating rod via a telescopic rod, and a level is provided at the connection between the operating rod and the telescopic rod.

[0012] A further improvement of this utility model is that the propulsion compartment is fixedly mounted on the support.

[0013] A further improvement of this utility model is that the bracket includes a support ring connected to the bottom end of the propulsion compartment and a support leg connected to the support ring, and the support leg is connected to the ground through the foot.

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] An electro-hydraulic insertion device, such as Figure 1-4 As shown, it includes a hydraulic control unit 4 fixedly mounted on the propulsion compartment 9 and a controller 13 connected to the hydraulic control unit 4. The controller 13 is a PLC control unit with intelligent control functions. Programs are written into the controller 13 as needed. During operation, the controller 13 receives input signals from position sensors and implements intelligent control according to preset programs and algorithms to meet various customer needs. This device, combining the stability of the hydraulic system and the high precision of electronic control, successfully solved the technical problem of winter nodal geophone insertion, ensuring the safe insertion of the tail cone of the nodal geophone 7 into the ground and completing the burial of the nodal geophone 7. It avoids the direct impact of a hammer during the previous nodal geophone insertion process, ensuring the integrity and good condition of the equipment, improving the quality of field data acquisition, and greatly increasing work efficiency.

[0025] like Figure 1 and Figure 4 As shown, the hydraulic control unit 4 includes an oil tank, a hydraulic valve 4-1, a hydraulic pump 4-2, and a hydraulic cylinder 4-3 connected by pipelines. The oil tank stores hydraulic oil; the hydraulic pump 4-2 is the power source of the hydraulic system, converting mechanical energy into the pressure energy of the hydraulic oil; the hydraulic valve 4-1 is a control element used to regulate the flow direction, flow rate, and pressure of the hydraulic oil to ensure stable system operation. The hydraulic cylinder 4-3 is the actuator of the hydraulic control unit 4, which converts hydraulic energy into mechanical energy to achieve linear motion through the pressure of the hydraulic oil, completing the extension and retraction of the piston rod 5, thereby smoothly realizing the insertion of the node detector 7.

[0026] The end of the piston rod 5 of the hydraulic cylinder 4-3 is connected to the top of the node detector 7, which is installed in the propulsion compartment 9. When the hydraulic cylinder 4-3 extends outward, the piston rod 5 pushes the node detector 7 down along the inner wall of the propulsion compartment 9 to complete the insertion of the node detector 7.

[0027] like Figure 1As shown, the node detector 7 is connected to the piston rod 5 via a gasket 6. The gasket 6 increases the contact area between the piston rod 5 and the node detector 7, and the gasket 6 is elastic, which acts as a buffer during the pushing process, effectively preventing the piston rod 5 from directly contacting the node detector 7 during insertion, thus effectively protecting the node detector 7 and avoiding accidental damage to it.

[0028] like Figure 1 and Figure 2 As shown, the node detector 7 is connected to the propulsion compartment 9 via clamping plates 8. The clamping plates 8 are elastic and evenly distributed on the inner wall of the propulsion compartment 9 to secure the node detector 7. The upper part of the node detector 7 has a cubic structure, and the evenly distributed clamping plates 8 can tightly clamp the four sides of the node detector 7 from the front, back, left, and right directions. During insertion, as the node detector 7 passively moves downward along the clamping plates 8, the clamping plates 8 will continuously clamp the node detector 7, ensuring that the node detector 7 moves vertically downward without tilting. Therefore, the clamping plates 8 ensure that the node detector 7 is constantly clamped and kept vertical during the pressing and insertion process, guaranteeing the vertical insertion of the node detector 7. During the clamping or pressing process, the clamping plates 8 also support the node detector 7, effectively preventing accidental detachment and damage.

[0029] like Figure 4As shown, the input terminal of the controller 13 is connected to the position sensor, and the output terminal of the controller 13 is connected to the hydraulic valve 4-1 and the hydraulic pump 4-2 respectively. The position sensor can detect the real-time position information of the object being measured and transmit this information to the controller 13 in real time, ensuring the precise control of the controller 13. The position sensor includes a first position sensor 12 and a second position sensor 14. The first position sensor 12 is located at the end of the piston rod 5 and can detect the position information of the piston rod 5 in real time; the second position sensor 14 is located at the tail cone of the nodal detector 7 and can detect the insertion depth information of the nodal detector 7 in real time. During operation, after preparation, the power is turned on. When the first position sensor 12 transmits the information that the piston rod 5 is in contact with the top of the node detector 7 to the controller 13, and the position information of the first sensor 12 and the second sensor 14 are the set values, the controller 13 analyzes, judges, and compares the data. Then, the output of the controller 13 sends a command to the hydraulic valve 4-1 and the hydraulic pump 4-2. The hydraulic pump 4-2 converts mechanical energy into the pressure energy of the hydraulic oil. The hydraulic valve 4-1 adjusts the flow direction, flow rate, and pressure of the hydraulic oil to extend the hydraulic cylinder 4-3. The piston rod 5 of the hydraulic cylinder 4-3 pushes the node detector 7 downwards and moves it vertically down along the clamping plate 8 in the propulsion compartment 9. When the real-time insertion depth information of the node detector 7 detected by the second position sensor 14 reaches the set insertion depth value in the controller 13, the controller 13 sends a command to the hydraulic valve 4-1, which in turn commands the hydraulic cylinder 4-3 to stop extending. The precise control of the insertion depth of the nodal geophone 7 into the ground was successfully achieved. Its fast, stable and high-precision vertical insertion process ensured the quality of field data acquisition. Moreover, the entire construction process is suitable for single-person operation, which greatly improves work efficiency.

[0030] After the insertion of the nodal detector 7 is completed, after a set time of 3 or 5 seconds, the controller 13 sends a command to the hydraulic valve 4-1 again. The hydraulic valve 4-1 controls the retraction of the hydraulic cylinder 4-3, causing the piston rod 5 of the hydraulic cylinder 4-3 to retract and gradually move away from the top of the nodal detector 7. This continues until the first position sensor 12 detects that the position information of the piston rod 5 has reached the set value of the controller 13. At this point, the controller 13 simultaneously sends commands to the hydraulic valve 4-1 and the hydraulic pump 4-2 to stop operation. The entire insertion process avoids the impact of the hammer, ensuring the integrity and good working order of the nodal detector 7, and greatly extending its service life.

[0031] like Figure 1As shown, the hydraulic control unit 4 is connected to the operating rod 1 via a telescopic rod 3. A level 2 is installed at the connection point between the operating rod 1 and the telescopic rod 3. The telescopic design of the telescopic rod 3 facilitates the insertion of the nodal detector 7 by operators of different heights and on various terrains. The level 2 ensures the vertical insertion of the nodal detector, preventing tilting during insertion and thus avoiding inaccurate data acquisition.

[0032] The propulsion compartment 9 is fixedly mounted on the support 11. For example... Figure 3 As shown, the support 11 is a foldable tripod. After use, the support 11 can be folded and stored to avoid taking up too much space. During the insertion process, the folded support 11 is first unfolded, and then the device is placed on the support 11 for operation, making the entire insertion process more comfortable and easier.

[0033] The support frame 11 includes a support ring 11-2 connected to the bottom end of the propulsion compartment 9 and three legs 11-3 connected to the support ring 11-2. The three legs 11-3 are evenly distributed on the circumference of the support ring 11-2, and together they stably support the support ring 11-2.

[0034] The support leg 11-3 is connected to the ground via the foot 11-4. The foot 11-4 increases the contact area between the support leg 11-3 and the ground, ensuring a firm connection. A ground nail 11-5 is fixedly installed below the foot 11-4, allowing it to be stably driven into the ground and guaranteeing the stability of the support 11. The support leg 11-3 and the ground nail 11-5 ensure a firm and stable connection between the support 11 and the ground, guaranteeing the smooth, stable, and vertical insertion of the tail cone of the node detector 7 into the ground.

[0035] The support ring 11-2 is provided with a buckle 11-1, which corresponds to the slot 10 at the bottom of the propulsion compartment 9. The propulsion compartment 9 and the support ring 11-2 are firmly connected by the buckle 11-1 and the slot 10. The buckle 11-1 and the slot 10 facilitate the connection and disassembly of the bracket 11 and the propulsion compartment 9.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are by no means intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description; it is impossible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom still fall within the protection scope of this invention.
