Description

Technical Field

[0001] The utility model relates to the technical field of applied geophysical exploration, in particular to a wading and attitude stabilizing device for a ground penetrating radar whip antenna. Background Art

[0002] When collecting ground-penetrating radar data in water-logged areas, the whip antenna must be secured to a floating object free of metal objects to ensure smooth data collection. When collecting radar data in areas with undulating terrain, the whip antenna must also be fixed to maintain its position parallel to the survey line. Field surveying often involves encountering water or undulating terrain. Currently, most radar antennas are shielded from water by constructing floating structures such as rafts, with wooden sticks used to adjust the antenna's position at the end. This presents several challenges: First, building a raft is time-consuming and labor-intensive, and metal parts are not suitable. Second, the antenna will sway when floating on water due to the effects of waves. Third, when the terrain is undulating, the flexible whip radar antenna is difficult to fix during mobile surveying, making it prone to distortion, which can affect data collection. Summary of the Invention

[0003] The purpose of the utility model is to provide a wading and attitude stabilizing device for a whip antenna of a ground penetrating radar, which solves the problem that the existing whip geological radar antenna is difficult to use in wading areas and areas with undulating terrain.

DETAILED DESCRIPTION

[0023] The above and other technical features and advantages of the present invention are described in more detail below with reference to the accompanying drawings.

[0024] This embodiment provides a technical solution: a wading and attitude stabilization device for a ground penetrating radar whip antenna, comprising an antenna sleeve, a connecting tube 1 and a tail end fixing tube 3;

[0025] The antenna sleeve is used to seal the antenna main structure;

[0026] The connecting tube 1 is connected to one end of the antenna sleeve and is used to insert the connecting cable and pull the antenna body;

[0027] The tail end fixing tube 3 is connected to the other end of the antenna sleeve, and the antenna posture is controlled and adjusted by controlling the tail end fixing tube 3 to cooperate with the connecting tube 1.

[0028] The antenna sleeve is divided into two sections, front and rear. One end of the front section 4 of the antenna sleeve is provided with a first internal thread 7, and the other end is provided with a first external thread 8. One end of the rear section 5 of the antenna sleeve is provided with a second internal thread 9, and the other end is provided with a third internal thread 10. The front section 4 of the antenna sleeve and the rear section 5 of the antenna sleeve are screwed into one through the first external thread 8 and the second internal thread 9.

[0029] The connection point between the front section 4 of the antenna sleeve and the rear section 5 of the antenna sleeve is located in the middle of the long side direction of the antenna sleeve.

[0030] The antenna connecting cable 12 of the whip radar passes through the connecting tube 1 and is connected to the main unit; the front section 4 of the antenna sleeve and the rear section 5 of the antenna sleeve respectively pass through the whip radar antenna connecting cable, and are screwed together at the tail end fixing tube 3. By inserting the connecting tube 1 and the tail end fixing tube 3 into the survey line position in shallow waters respectively, the underwater posture of the antenna sleeve is controlled by adjusting the water entry length of the head and tail ends so that the antenna sleeve always remains parallel to the water surface or close to the bottom of the water, thereby ensuring that the whip radar antenna in the antenna sleeve also remains parallel to the water surface or close to the bottom of the water.

[0031] A second external thread 6 is provided below the fixing tube and is screwed together with the first internal thread 7 of the front section 4 of the antenna sleeve.

[0032] A third external thread 11 is provided below the tail end fixing tube 3 and is screwed together with the third internal thread 10 of the rear section 5 of the antenna sleeve.

[0033] like Figure 1-Figure 3 As shown,

[0034] By pulling the connecting tube 1 to move the antenna as a whole, the flexible whip radar antenna is fixed in the sleeve to form a rigid whole. Controlling the movement direction of the tail fixing tube 3 and the connecting tube 1 can ensure the stability of the radar detection position and the stability of the collected data. The waterproof and water-resistant characteristics of the antenna sleeve after connection overcome the defect of the whip radar antenna being non-waterproof, realizing the water data collection of shallow water ground penetrating radar.

[0035] In this embodiment, the overall design of the components is symmetrical and can be used symmetrically. When in use, the whip radar antenna can be inserted into the antenna sleeve and then connected to the host through the connecting tube 1. It can also be inserted into the antenna sleeve in the opposite direction and then connected to the host through the tail connecting tube 1. When the tail fixing tube 3 is inserted with a cable, the whip radar antenna can be moved as a whole by pulling the tail fixing tube 3. The connecting tube 1 is used to adjust the overall posture of the antenna.

[0036] In areas with undulating terrain and where the survey line is parallel to the terrain line, the radar antenna will slide down due to gravity when it moves to collect data, causing the measuring point to deviate from the established position and generate errors. After inserting the whip radar antenna into the antenna sleeve, it is restricted to a rigid structure. When pulling the connecting tube 1 to move the antenna, it is only necessary to hold the tail fixing tube 3 to prevent it from sliding down to ensure that the antenna position is stable on the established survey line.
