Description

Technical Field

[0001] This utility model relates to the field of seismic exploration equipment technology, and in particular to a cable with a retractable detector. Background Technology

[0002] In shallow earthquake or engineering seismic exploration operations, there are usually specific requirements for the geophone spacing.

[0003] Traditional detectors and cables are mostly separate units. During installation, detectors need to be installed one by one at intervals of 5-10m, which is cumbersome and makes it difficult to flexibly adjust the position of the detectors within a small range.

[0004] Meanwhile, traditional cable laying and winding rely on manual labor, which is not only time-consuming and labor-intensive, but also extremely inconvenient for construction during large-scale exploration, seriously affecting work efficiency.

[0005] Therefore, developing a device that can extend and retract within a few meters, with a spacing of 5-10 meters, and with easy cable retraction and simple construction is key to improving exploration efficiency. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a cable with a retractable detector, including a cable body and an electric winch. The cable body is wound on the electric winch, and multiple detector assemblies are connected to the outer end of the cable body.

[0008] The detector assembly includes an automatic take-up device, which has an electric wire wound inside. The two ends of the electric wire extend to the front and rear sides of the automatic take-up device, respectively. The rear end of the electric wire is electrically connected to the cable body, and the front end of the electric wire is fixedly connected to a detector. The outer end of the electric wire is machined with two scale lines, and the two scale lines are respectively starting from the two ends.

[0009] Preferably, the outer end of the cable body is fixedly connected to multiple connecting end seats, the rear end of the wire is fixedly connected to a connecting end, the connecting end is inserted into the connecting end seats, and the detector is electrically connected to the cable body through the wire, the connecting end and the connecting end seats.

[0010] Preferably, a receiving tube is fixedly connected to the front side of the automatic retractor, the scale line passes through the receiving tube, and the detector is adapted to the interior of the receiving tube.

[0011] Preferably, the storage tube has notches at both the top and bottom of its front side.

[0012] Preferably, the bottom of the automatic retractor is fixedly connected to a retaining sleeve, and the automatic retractor can be secured to the outer end of the cable body by the retaining sleeve.

[0013] Compared with related technologies, the cable with a retractable detector provided by this utility model has the following advantages:

[0014] The cable body can be quickly wound up and down using an electric winch, while the wires connecting the cable body and the detector in the detector assembly are wound up using an automatic take-up device. The wires are always wound up and taut when adjusting the position of the detector. The specific spacing can be quickly determined by using the scale lines. At the same time, the detector assembly can be fixed to the cable body without disassembly when the cable body is being wound up. The overall operation is simple, which greatly improves the exploration efficiency and is suitable for various exploration scenarios. Attached Figure Description

[0020] Please see Figure 1-4 The technical solution provided by this utility model specifically includes the following embodiments:

[0021] A cable with a retractable detector includes a cable body 2 and an electric winch 1. The cable body 2 is wound onto the electric winch 1, and a plurality of detector assemblies 3 are connected to the outer end of the cable body 2.

[0022] The detector assembly 3 includes an automatic take-up device 31, which has an electric wire 32 wound inside. The two ends of the electric wire 32 extend to the front and rear sides of the automatic take-up device 31, respectively. The rear end of the electric wire 32 is electrically connected to the cable body 2. The front end of the electric wire 32 is fixedly connected to a detector 34. The outer end of the electric wire 32 is processed with two scale lines 321, and the two scale lines 321 are respectively starting from the two ends.

[0023] With the help of electric winch 1, the overall cable winding and unwinding is extremely convenient, requiring no large amount of manpower and can be operated by a single person.

[0024] The data acquisition instrument is connected to the end of the cable body 2. The detector 34 needs to be telescopic within 3-5 meters, and the spacing of the detectors 34 needs to be within 5-10 meters.

[0025] The length of the wire 32 extending from the automatic retractor 31 can be determined by the scale line 321. When the wire 32 extends from the automatic retractor 31, both ends extend or retract simultaneously, and the lengths of both ends are the same. Therefore, the actual stretching length of the detector 34 can be obtained by adding the scale readings of the two wires 32 on the scale line 321. When not in use, the automatic retractor 31 will automatically retract the wire 32.

[0026] The outer end of the cable body 2 is fixedly connected to a plurality of connecting end seats 21, and the rear end of the wire 32 is fixedly connected to a connecting end head 33. The connecting end head 33 is inserted into the connecting end seat 21, and the detector 34 is electrically connected to the cable body 2 through the wire 32, the connecting end head 33 and the connecting end seat 21.

[0027] The connecting end 21 and the connecting end 33 can be plug-in or spiral-connected depending on the actual model, and then the signal transmission connection between the cable body 2 and the detector 34 is realized through the wire 32.

[0028] The automatic retractor 31 is fixedly connected to a storage tube 35 at its front. The scale line 321 passes through the storage tube 35, and the detector 34 is adapted to the interior of the storage tube 35. Notches 351 are provided at the top and bottom of the front side of the storage tube 35. When the detector assembly 3 is being stored, the automatic retractor 31 winds up the wire 32, during which the detector 34 can be stored in the storage tube 35. The notches 351 facilitate the removal of the detector 34 from the storage tube 35.

[0029] The bottom of the automatic take-up device 31 is fixedly connected to a retaining sleeve 4. The automatic take-up device 31 can be fixed to the outer end of the cable body 2 by the retaining sleeve 4. The retaining sleeve 4 can be used to fix the automatic take-up device 31 to the cable body 2, so that the detector 34 does not need to be removed when the cable body 2 is wound by the electric winch 1.

[0030] The automatic retractor 31 is an existing product. Similar retractable charging cable retractors also exist. Their main structure includes a housing 311, with a winding spool 312 movably connected inside the housing 311. A coil spring 313 is installed between the outer end of the winding spool 312 and the inner wall of the housing 311. A partition 314 can also be installed inside the housing 311 to separate the wound wire 32 from the coil spring 313. The housing 311 has a wire hole 315 at the front and back for the wire 32 to pass through. A locking mechanism (not shown in the figure) can also be added inside, which can automatically hold the wire 32 after it is stretched to a certain length. Pulling it again will automatically retract the wire 32. Since the automatic retractor 31 is an existing product, it will not be described in detail here.

[0031] The integrated design eliminates the cumbersome assembly steps of traditional equipment. The detector position adjustment and cable winding and unwinding operations are simple and easy to understand, which greatly shortens the construction preparation time and reduces the construction difficulty. Even in complex terrain, operations can be carried out quickly.

[0032] Working principle:

[0033] When not in use, the cable body 2 is wound up by the electric winch 1. When the cable body 2 is unfolded for use, the multiple detector assemblies 3 on the outside of the cable body 2 can be unfolded and used. The automatic take-up device 31 can be moved by removing the retainer 4 from the cable body 2. At this time, the detector 34 in the take-up tube 35 is pulled out. During this process, the wire 32 is pulled out from both ends from inside the automatic take-up device 31. The length of the wire 32 pulled out can be determined by the scale line 321 on the wire 32, and thus the extension length of the detector 34 can be determined. When it is time to retract the cable after use, the automatic take-up device 31 will automatically retract the wire 32, so that the entire detector assembly 3 is in the retracted state. Then, the retainer 4 is used to fix the automatic take-up device 31 to the outside of the cable body 2. Finally, the cable body 2 is wound up by the electric winch 1. The detector 34 does not need to be removed from the cable body 2 throughout the process.
