Abstract
Description
Technical Field
[0001] This utility model relates to the field of surveying and mapping technology, and in particular to a multi-frequency electromagnetic scanning auxiliary tool. Background Technology
[0002] In current multi-frequency electromagnetic scanning field operations, operators need to simultaneously operate a multi-frequency electromagnetic scanner and a high-precision GPS positioning device (such as RTK). Operating both devices alone is clearly strenuous, and even with two people, perfect synchronization between the detection and positioning points is impossible. Some users mount both devices on the same backpack, but backpacks in current technology are typically flexible structures, making the distance between the multi-frequency electromagnetic scanner and the RTK positioning device unstable and prone to inaccurate detection and positioning data. Furthermore, the multi-frequency electromagnetic scanner has a long, strip-shaped structure with both horizontal and vertical scanning modes. For horizontal scanning, the scanner can be directly hung on the bottom of the backpack, but for vertical scanning, the user needs to place the scanner at their side, which is inconvenient for securing the scanner to the backpack. Utility Model Content
[0003] In view of the above-mentioned deficiencies of the prior art, the present invention provides a multi-frequency electromagnetic scanning auxiliary tool, which adopts a rigid frame structure, can simultaneously fix RTK equipment and multi-frequency electromagnetic scanning equipment, and has a horizontal scanning configuration and a vertical scanning configuration, so as to solve the problems existing in the prior art.
[0004] To achieve the above objectives, this utility model provides a multi-frequency electromagnetic scanning auxiliary tool, which includes: a back box frame and a mounting frame;
[0005] The back of the back frame is provided with two shoulder straps.
[0006] A mounting frame is used to clamp and fix a strip-shaped multi-frequency electromagnetic instrument, the two ends of which extend from both sides of the mounting frame.
[0007] When a horizontal configuration is adopted, the mounting frame is fixedly installed directly below the back box frame, so that the multi-frequency electromagnetic instrument is located behind the carrier and extends in the left and right direction;
[0008] When a longitudinal configuration is adopted, the top edge of the back of the mounting frame is connected to the bottom edge of the side of the back box frame, so that the multi-frequency electromagnetic instrument extends in the front-to-back direction and is located on the side of the person carrying it.
[0009] A further improvement of this utility model is that a main column is provided on the back box frame, and the RTK head is installed at the top of the main column.
[0010] A further improvement of this utility model is that the mounting frame includes four mounting frame uprights, two of which are located on both sides of the back and side of the mounting frame, and the other two are located on both sides of the outer surface of the mounting frame; the back and side are opposite to the outer surface.
[0011] A further improvement of this utility model is that, when a horizontal configuration is adopted, two long screws pass through the mounting frame uprights on both sides of the mounting frame from bottom to top, and form a threaded connection with the internal threads at the bottom of the back box frame uprights on both sides of the back box frame; the top horizontal bar on the outer surface of the mounting frame is fixedly connected to the bottom horizontal bar on the outer surface of the back box frame by connecting bolts.
[0012] A further improvement of this utility model is that, in the case of a longitudinal configuration, a long screw passes through the mounting frame riser on the right side of the back of the mounting frame from bottom to top, and forms a threaded connection with the internal thread at the bottom end of the back frame riser on the right side of the back of the back frame; another long screw passes through the bottom crossbar and the top crossbar of the back of the mounting frame from bottom to top, and forms a threaded connection with the internal thread at the bottom end of the back frame riser on the right side of the outer surface of the back frame; thereby fixing the mounting frame to the bottom side of the back frame.
[0013] A further improvement of this utility model is that: a gasket is provided on the side of the mounting frame upright tubes on both sides of the back of the mounting frame facing the outer surface; clamping bolts are provided on the mounting frame upright tubes on both sides of the outer surface, and clamping plates adapted to the gaskets are provided at the ends of the clamping bolts; the gaskets and clamping plates are used to clamp the multi-frequency electromagnetic instrument from both sides under the pushing of the clamping bolts.
[0014] A further improvement of this utility model is that: both the back box frame and the mounting frame are made of PVC pipe; and each surface of the back box frame is provided with a sealing plate.
[0015] The method provided by this utility model has the following technical effects:
[0016] The rigid mechanical connection between the back box (RTK fixed) and the mounting device (multi-frequency electromagnetic instrument fixed) forces the spatial relationship between the two devices to be bound, eliminating the positional offset caused by the traditional separate holding mode (the measured spatial synchronization error is ≤2cm vs. the traditional mode is >50cm), and ensuring that the detection coordinates and the positioning coordinates are strictly corresponding.
[0017] The integrated load-bearing design (back box + mounting frame) allows a single operator to simultaneously control two devices, and through the two mounting configurations of the mounting frame, stable lateral and longitudinal scanning can be achieved.
[0018] The following will further explain the concept, specific structure and technical effects of this utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of this utility model. Attached Figure Description

[0026] Some exemplary embodiments of the present invention have been described for illustrative purposes. It should be understood that the present invention may be implemented in other ways not specifically shown in the accompanying drawings.
[0027] like Figure 1As shown, this embodiment provides a multi-frequency electromagnetic scanning auxiliary tool, which has a back box frame (10) and a mounting frame (30).
[0028] Two shoulder straps (11) are provided on both sides of the back cover 15 of the backpack frame (10) for the carryer to drape over their shoulders. A main support pole (12) is provided on the backpack frame (10), and the RTK head (13) is installed at the top of the main support pole (12). In this embodiment, the backpack frame (10) is cubic in shape, with a length of 30cm, a width of 20cm, and a height of 35cm; it is made of PVC pipe with a diameter of 20mm. The main support pole (12) is made of PVC pipe with a diameter of 35mm, has a length of 70cm, is fixed in the middle of the backpack frame (10), and extends upward.
[0029] The mounting frame 30 is used to clamp and fix the strip-shaped multi-frequency electromagnetic instrument 40, with both ends of the multi-frequency electromagnetic instrument 40 extending from both sides of the mounting frame 30. The mounting frame 30 is 30cm long, 20cm wide, and 10cm high, and is composed of PVC pipe with a diameter of 20mm.
[0030] like Figure 1 , Figure 3 , Figure 4 As shown, when the horizontal configuration is adopted, the mounting frame 30 is fixedly installed directly below the back box frame 10, so that the multi-frequency electromagnetic instrument 40 is located behind the person carrying it and extends in the left and right direction.
[0031] like Figure 2 , Figure 3 , Figure 4 As shown, when the longitudinal configuration is adopted, the top edge of the back side of the mounting frame 30 is connected to the bottom edge of the side of the back box frame 10, so that the multi-frequency electromagnetic instrument 40 extends in the front-back direction and is located on the side of the person carrying it.
[0032] like Figure 4 As shown, in this embodiment, the mounting frame 30 includes four mounting frame risers 31, two of which are located on both sides of the back cover 37 of the mounting frame 30, and the other two are located on both sides of the outer surface 38 of the mounting frame 30; the back cover 37 is opposite to the outer surface 38.
[0033] In the lateral configuration, two long screws 32 pass through the mounting frame risers 31 on both sides of the back side 37 of the mounting frame 30 from bottom to top, and form a threaded connection with the internal threads at the bottom ends of the back box frame risers 14 on both sides of the back side 15 of the back box frame 10; the top crossbar of the outer surface 16 of the mounting frame 30 is fixedly connected to the bottom crossbar of the outer surface of the back box frame 10 by two connecting bolts 33. The back box frame 10 is similar to the mounting frame 30, with its outer surface 16 facing the back side 15. The four back box frame risers 14 of the back box frame 10 correspond one-to-one with the mounting frame risers 31 of the mounting frame 30, so that the top surfaces of the back box frame 10 and the mounting frame 30 coincide when the lateral configuration is adopted.
[0034] In the longitudinal configuration, a long screw 32 passes from bottom to top through the mounting frame riser 31 on the right side of the back of the mounting frame 30, and forms a threaded connection with the internal thread at the bottom end of the back frame riser 14 on the right side of the back of the back frame 10; another long screw 32 passes from bottom to top through the bottom crossbar 20 and the top crossbar 21 on the back of the mounting frame 30, and forms a threaded connection with the internal thread at the bottom end of the back frame riser 14 on the right side of the outer surface of the back frame 10; thereby fixing the mounting frame 30 to the bottom side of the back frame 10. To allow the long screw 32 to pass through, the bottom crossbar 20 and the top crossbar 21 on the back of the mounting frame 30 have through holes 22 at corresponding positions.
[0035] On the opposite sides of the mounting frame 30, the mounting frame risers 31 facing outwards are provided with gaskets 34; clamping bolts 35 are provided on the mounting frame risers 31 on both sides of the outer surface, and clamping plates 36 adapted to the gaskets 34 are provided at the ends of the clamping bolts 35; the gaskets 34 and the clamping plates 36 are used to clamp the multi-frequency electromagnetic instrument 40 from both sides under the pushing force of the clamping bolts 35. Specifically, in this embodiment, the mounting frame risers 31 on both sides of the outer surface of the mounting frame 30 have threaded holes for the clamping bolts 35 to be installed. The inner wall of the threaded holes is provided with internal threads, and the extension line of the axis of the threaded holes passes through the gaskets 34, so that the clamping plates 36 and the gaskets 34 are at the same height. The clamping plates 36 are installed at the end of the clamping bolts 35 facing the gaskets 34, and the other end of the clamping bolts 35 has a hexagonal structure.
[0036] Both the back box frame 10 and the mounting frame 30 are made of PVC pipe; each surface of the back box frame 10 is provided with a sealing plate (not shown in the figure). The sealing plate is a detachable structure, and in some embodiments, the space enclosed by the sealing plate can accommodate batteries, communication equipment, and signal processing equipment.
[0037] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model.
