Description

Technical Field

[0001] The utility model belongs to the technical field of geophysical exploration, and particularly relates to a four-way wire releasing and winding device. Background Technique

[0002] Magnetotelluric sounding is a geophysical exploration method and belongs to a branch of electrical methods. It measures depth by changing the frequency of the electromagnetic field and utilizes the skin effect of electromagnetic induction. High-frequency electromagnetic fields penetrate shallowly, while low-frequency electromagnetic fields penetrate deeply.

[0003] When a magnetotelluric instrument is in use, since it is necessary to deploy pole cans in four directions of east, west, south, and north to receive electrical signals, usually, each pole can needs to be connected to the host through a signal line about 50 meters long. During the process of setting up a station in the wild, 4 long signal lines need to be laid out in four directions; during the process of taking down the station, the signal lines need to be wound and retracted. This process of wire releasing and winding is all manually operated by construction workers, consuming a large amount of time and energy, and it is very easy for the signal lines to be wound around each other during the process of wire releasing and winding, and it is even difficult to untangle them; at the same time, the manually wound signal lines are exposed without a protection device during transportation, and the terrain conditions in the wild operation are poor, and the vehicle travels bumpily, so the signal lines are easily squeezed by heavy objects or sharp objects during transportation, resulting in signal line breakage. In the actual process of field construction, the instrument needs to be taken down and set up multiple times every day. This manual winding and removal method consumes a lot of time and energy when winding or removing the signal lines on multiple pole cans, and the work efficiency is low. To solve these problems, the utility model proposes a four-way wire releasing and winding device. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model. Specific Embodiment 1:

[0027] Please refer to Figures 1-5As shown in the figure, the utility model relates to a four-way wire winding and unwinding device, which includes a wire unwinding base 1, four wire winding and unwinding devices 2, and four laser pointers 3. Among them, the wire unwinding base 1 is in the central position during wire unwinding. The four wire winding and unwinding devices 2 are distributed around in a cross manner in four directions for wiring. The four laser pointers 3 irradiate the four wire winding and unwinding devices 2 to quickly and accurately locate the layout orientation of each pole tank.

[0028] Among them, the wire unwinding base 1 specifically includes a rectangular groove 11. A rectangular tube 12 is vertically fixed at the bottom of the rectangular groove 11. In the middle of the four side walls at the upper end of the rectangular tube 12, a cylindrical tube 13 for inserting and installing the laser pointer 3 is penetrated and fixed. Before positioning the rectangular groove 11, a direction pointing device, such as a compass, is used to adjust the rectangular tube 12 so that its four sides respectively correspond to four directions. The direction pointing device can be fixed on one side or the top surface of the positioning rectangular groove 11.

[0029] Among them, in order to facilitate the limitation of one end of the signal line connected to the geomagnetic signal processing device, a first wire passing hole 14 is respectively opened in the middle of the four side walls of the rectangular tube 12. A second C-shaped wire clamping plate 15 is respectively installed on the four side walls of the rectangular tube 12 through bolts, and the second C-shaped wire clamping plate 15 is located directly below the first wire passing hole 14. The signal line is pressed under the second C-shaped wire clamping plate 15 for positioning, and the plug ends all pass through the first wire passing hole 14 to the inside of the rectangular tube 12, which is convenient for the four signal lines to be connected to the geomagnetic signal processing device for use.

[0030] Among them, in order to prevent the wire winding and unwinding device 2 from moving after being received on the wire unwinding base 1, a pair of limiting plates 16 are symmetrically fixed on the edge parts of the four side walls of the rectangular tube 12. When the wire winding and unwinding device 2 is installed in the rectangular groove 11, it is placed between a pair of limiting plates 16.

[0031] Among them, in order to facilitate the movement of the wire unwinding base 1 and the transfer of the test site, two self-locking universal wheels 17 and two directional wheels 18 are installed on the bottom surface of the rectangular groove 11. A handle rod 19 for pushing and pulling is fixed on a pair of opposite outer walls of the rectangular groove 11.

[0032] The wire winding and unwinding device 2 specifically includes a frame 21 and a wire reel 22 rotatably installed on the frame 21 for winding the signal line. A first C-shaped wire clamping plate 23 is installed on the wire reel 22 through bolts. The connection end of the signal line and the pole tank of the magnetotelluric instrument is positioned through the first C-shaped wire clamping plate 23, which is convenient for quick connection and use after the wiring is completed.

[0033] In order to reduce the labor in the process of winding and releasing the wire, the wire retractor 2 also includes a motor 26, a power supply 24 and a two-way speed regulating switch 25 installed on the frame 21. One end of the motor 26 is connected to one end of the wire drum 22 through a gear set 27. When the wire retractor 2 is used for auxiliary winding and releasing, the rotation speed of the wire drum 22 is adjusted by the two-way speed regulating switch 25 to adapt to the walking speed of the user, which can greatly reduce the labor of manual wiring and winding during the wiring process.

[0034] In order to further facilitate the application of force during wiring and winding, the frame 21 includes a rectangular frame 211. The wire drum 22 is mounted on the rectangular frame 211 through two seat bearings. Two first fixed columns 212 are fixed to one side end of the lower surface of the rectangular frame 211, and two second fixed columns 213 are fixed to the other side end. An auxiliary wheel 214 is respectively installed at the lower end of the two second fixed columns 213. When the rectangular frame 211 is placed in a horizontal state, the first fixed column 212 and the auxiliary wheel 214 are in contact with the ground. An inverted U-shaped rod 215 is fixed to the upper surface of the rectangular frame 211, and the U-shaped rod 215 is located directly above the second fixed column 213. By setting the auxiliary wheel 214, the rolling friction between the wire reel 2 and the ground during the movement of the dragging wire reel 2 is reduced, and the overall load is reduced compared to the manual winding and unwinding of the wire cable on itself, which is convenient for quick wiring.

[0035] In order to accurately wire in four directions, an acrylic plate 28 is fixed on the frame 21. When the frame 21 and the rectangular slot 11 are placed on the same horizontal bottom surface, the center height of the acrylic plate 28 is at the same horizontal height as the center line of the cylindrical tube 13. If the light of the laser pen 3 can hit the acrylic plate 28, it means that the wiring direction of the retractable wire 2 is correct. When it is found that there is no light of the laser pen 3 on the acrylic plate 28, the deviation correction can be quickly adjusted to achieve the purpose of fast and accurate wiring.
