Example one

As shown in fig. 1 and fig. 2, the north seeker mounting base according to the present embodiment includes a bottom plate 1, a supporting plate 5, a supporting screw 3, and a leveling nut 4, where the bottom plate 1 and the supporting plate 5 are stacked, that is, the bottom plate 1 is located above the supporting plate 5, the bottom plate 1 and the supporting plate 5 may be an elongated plate, a square plate, a circular plate, or the like, and the shape of the plate is selected according to a requirement, in this example, the bottom plate 1 and the supporting plate 5 are both rectangular plates, as shown in fig. 2. The upper surface of the bottom plate 1 is provided with the horizontal bubble 2 and the north seeker 9, and the north seeker 9 is arranged in the middle of the upper surface of the bottom plate 1. The north seeker 9 is fixed on the bottom plate 1 through bolts, and is convenient to detach and carry separately.

The number of the horizontal bubbles 2 can be one or more, if one horizontal bubble 2 is used, the horizontal bubble needs to be installed close to the north seeker 9, and the closer to the north seeker 9, the higher the horizontal accuracy is; if a plurality of the bubble leveling devices are adopted, the bubble leveling devices are uniformly distributed along the peripheral sides of the north seeker 9, and after the plurality of the bubble leveling devices 2 are leveled, the peripheral sides of the north seeker 9 are horizontal, so that the horizontal accuracy of the north seeker 9 is high. Preferably, in this example, there are two horizontal bubbles 2, which are arranged on two sides of the north seeker 9 along the longitudinal axis of the rectangular plate, as shown in fig. 2, so as to adapt to the arrangement of the rectangular plate, ensure the leveling of the north seeker 9, and further ensure the accuracy of the data tested by the north seeker 9.

A plurality of through round holes are arranged on the bottom plate 1 and are uniformly distributed along the circumferential direction of the bottom plate 1; the supporting screws 3 and the leveling nuts 4 are provided with a plurality of supporting screws, one ends of the supporting screws 3 penetrate through the round holes in a sliding mode and are connected with the supporting plates 5, the other ends of the supporting screws are cap ends, the cap ends are located on the top surface of the bottom plate 1, the diameters of the cap ends are larger than those of the round holes, the round holes can clamp the cap ends, and therefore the cap ends can stay on the top surface of the bottom plate 1. The leveling nut 4 is in threaded connection with a screw part of the supporting screw 3 and is positioned between the bottom plate 1 and the supporting plate 5 to support the bottom plate 1, and a space is reserved between the bottom plate 1 and the supporting plate 5. Referring to fig. 1, the base plate 1 is supported by the leveling nut 4, and when the leveling nut 4 is screwed on the support screw 3, the distance between the base plate 1 and the support plate 5 is changed. The supporting screws 3 and the leveling nuts 4 are all used for adjusting the level of the bottom plate 1, so that the number of the supporting screws and the leveling nuts can be set according to requirements. In this example, three circular holes, three support screws 3 and three leveling nuts 4 are provided, as shown in fig. 2.

When the multifunctional adjustable support plate is used in the field, the field ground is various and complex and is hollow, and a smooth surface cannot be guaranteed to be used as a base adjusting surface for the bottom plate 1, so that the support plate 5 can be used as the base adjusting surface, and even if the field ground is hollow, the basic level of the support plate 5 can be realized by adopting multi-point support, so that the multifunctional adjustable support plate can adapt to the field complex terrain. During the use, place backup pad 5 subaerial, guarantee backup pad 5 level as far as possible when placing backup pad 5, later adjust leveling nut 4 fine setting, observe level bubble 2 simultaneously, can measure north seeker 9 adjustment level.

During field operation, the topography is complicated changeable, and in order to adapt to different topography demands, north seeker 9 of this example settles the base and still includes adjustable support frame, and adjustable support frame demountable installation is in the lower surface middle part of backup pad 5, modes such as accessible draw-in groove, bolt. The adjustable support frame includes connecting plate, tripod, and the connecting plate can be dismantled with backup pad 5 and be connected, and the tripod is connected with the connecting plate, and the tripod comprises three telescopic link, and the top and the connecting plate of telescopic link are connected, and the bottom head is equipped with the toper point, and the support that stabilizes in the conical point conveniently stretches into ground, and the telescopic link can adopt the structure that two pole covers were established, through fastening screw 7 locking two poles to realize flexible adjustment. The telescopic rod is provided with the pedal, the pedal is arranged close to the conical tip, the pedal is convenient for a user to step on to insert the conical tip into the ground, and meanwhile the pedal has a certain area, so that the situation that the conical tip is inserted into the ground too deeply is avoided.

When using, step on the running-board with the foot and inject the toper type point into ground, adjustment telescopic link length, no matter what kind of length is used to three telescopic link, only need guarantee the connecting plate basically be the level form can, be connected backup pad 5 and connecting plate again, realize the outrigger to backup pad 5. Because different length adjustment can be realized to the three telescopic link of adjustable support frame, consequently can use this structure in complicated topography, can satisfy and use in various topography, the homoenergetic of guarantee north seeker 9 in different topography realizes measuring.

In the embodiment, the bottom plate 1 and the support plate 5 are both stainless steel plates, preferably stainless steel with hardness not lower than 304, the thickness of the bottom plate 1 can be 1cm, and the thickness of the support plate 5 can also be 1 cm; the supporting screws 3 can be stainless steel knurled screw heads screwed by hands, the length of the supporting screws is not more than 5cm, and the leveling nuts 4 can be knurled flat-head nuts screwed by hands with nickel plating. Of course, other types or materials can be selected as long as the support of the supporting plate 5 of the bottom plate 1 and the micro-leveling function of matching of screws and nuts are met.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the utility model as defined by the appended claims.
