Description

Technical Field

[0001] This utility model relates to the field of magnetic compass technology, specifically to a rapid self-difference correction support structure for marine magnetic compasses. Background Technology

[0002] In ship navigation, the magnetic compass is an indispensable navigation device, but it is highly susceptible to the self-bias caused by the magnetization of the ship's own steel structure, leading to a decrease in navigation accuracy. Traditional magnetic compass mounting brackets have limited angle adjustment capabilities, mostly simple adjustments in a single direction, making it difficult to cope with the complex magnetic field environment of ships. When the ship's navigation status changes or encounters geomagnetic variations in different sea areas, the self-bias correction process becomes cumbersome, often requiring multiple disassemblies and adjustments of the bracket. This is not only time-consuming and labor-intensive, but repeated operations may also affect the stability of the bracket installation, thereby affecting the measurement accuracy of the magnetic compass and posing a potential threat to the safe navigation of the ship. Therefore, a rapid self-bias correction bracket structure for marine magnetic compasses is proposed. Utility Model Content

[0003] In view of this, the present invention provides a rapid self-difference correction support structure for marine magnetic compasses to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0004] The technical solution of this utility model is implemented as follows: A marine magnetic compass rapid self-difference correction bracket structure includes a base, a spherical sleeve fixedly connected to the top of the base, a ball head installed inside the spherical sleeve, a second threaded hole installed on the top of the ball head, a ring fixedly connected to the outer ring of the second threaded hole, a bracket fixedly connected to the top of the ring, a magnetic compass installed on the top of the bracket, a second threaded hole opened on the top of both the ball head and the ring, a first bolt threadedly connected to the inner side wall of the second threaded hole, two rods symmetrically fixedly connected to the outer side wall of the ball head, one end of the rod penetrating the spherical sleeve, the outer side wall of the rod rotatably connected to the spherical sleeve through a bearing, an external gear fixedly connected to the outer side wall of the rod, two sliding grooves symmetrically opened on the upper surface of the base, a slider slidably connected to the inner side wall of the sliding groove, a fixing plate fixedly connected to the upper surface of the slider, an internal gear installed on one side of the fixing plate, and the external gear meshing with the internal gear.

[0005] More preferably, both the base and the slider have a third threaded hole on their upper surfaces, and the inner wall of the third threaded hole is threaded with a second bolt.

[0006] More preferably, the top of the base is provided with a plurality of first threaded holes evenly distributed.

[0007] The present invention has the following advantages due to the adoption of the above technical solution:

[0008] I. This utility model utilizes the rotation of the ball head within the spherical sleeve, the meshing transmission of the external and internal gears, and the fine-tuning effect of the ring to achieve flexible angle adjustment of the magnetic compass in multiple directions. It can accurately meet the self-error correction requirements under different conditions, significantly improving the flexibility and accuracy of self-error correction. The entire angle adjustment process does not require disassembling the bracket and can be completed through simple operations such as sliding the slider and tightening the bolts, simplifying the self-error correction process and saving a lot of correction time. It is especially suitable for scenarios where rapid self-error correction is required during ship navigation.

[0009] Second, the base of this utility model is fixed to the deck through multiple first threaded holes. Combined with the locking and fixing of the slider and the slide groove, and the tightening and fixing of the ball head by the first bolt, it ensures that the magnetic compass can be stably maintained at the set angle after adjustment. Even in complex navigation environments such as ship turbulence, the installation stability and measurement accuracy of the magnetic compass can be guaranteed.

[0015] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0016] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0017] like Figure 1-2 As shown, this utility model embodiment provides a rapid self-difference correction bracket structure for a marine magnetic compass, including a base 1. A spherical sleeve 3 is fixedly connected to the top of the base 1. A ball head 4 is installed inside the spherical sleeve 3. A second threaded hole 7 is installed on the top of the ball head 4. A ring 8 is fixedly connected to the outer ring of the second threaded hole 7. A bracket 9 is fixedly connected to the top of the ring 8. A magnetic compass 11 is installed on the top of the bracket 9. The tops of both the ball head 4 and the ring 8 are provided with second threaded holes 7. The inner sidewall of the second threaded hole 7 is threaded. There is a first bolt 10. Two rods 5 are symmetrically fixedly connected to the outer side wall of the ball head 4. One end of the rod 5 passes through the spherical sleeve 3. The outer side wall of the rod 5 is rotatably connected to the spherical sleeve 3 through a bearing. An external gear 6 is fixedly connected to the outer side wall of the rod 5. Two sliding grooves 12 are symmetrically opened on the upper surface of the base 1. A slider 13 is slidably connected to the inner side wall of the sliding groove 12. A fixing plate 16 is fixedly connected to the upper surface of the slider 13. An internal gear 17 is installed on one side of the fixing plate 16. The external gear 6 and the internal gear 17 are meshed and connected.

[0018] In one embodiment, the upper surfaces of both the base 1 and the slider 13 are provided with a third threaded hole 14, and the inner sidewall of the third threaded hole 14 is threaded with a second bolt 15.

[0019] In one embodiment, the top of the base 1 is provided with a plurality of first threaded holes 2 evenly distributed.

[0020] In operation, this invention works as follows: First, based on the installation position on the ship's deck, multiple first threaded holes 2 evenly spaced on the top of the base 1 are used to securely fix the base 1 to the ship's deck with bolts, ensuring a solid and reliable foundation for the entire support structure. When the magnetic compass 11 needs angle adjustment, the second bolt 15 in the third threaded hole 14 is loosened first, allowing the slider 13 to slide freely within the groove 12. The sliding slider 13 moves the fixing plate 16. Since the external gear 6 is meshed with the internal gear 17, the movement of the fixing plate 16 will disengage the internal gear 17 from the external gear 6, thereby causing the ball head 4 to rotate within the spherical sleeve 3 via the rod 5, achieving angle adjustment of the magnetic compass 11 within a certain range. Once the magnetic compass 11 is adjusted to a roughly suitable angle... Slide slider 13 to make internal gear 17 mesh tightly with external gear 6, then tighten second bolt 15 to fix slider 13 in slide groove 12, thereby fixing the current angle position. If further precise adjustment is required, the first bolt 10 can be unscrewed through the second threaded hole 7 on the top of ball head 4 and ring 8, and the angle of ring 8 can be adjusted by rotating ring 8. Then, the first bolt 10 can be inserted into the corresponding second threaded hole 7 on ring 8 and bottom ball head 4 to fix the angle of ring 8, so that magnetic compass 11 reaches the ideal angle. If self-error is found in magnetic compass 11 during ship navigation, the angle of magnetic compass 11 can be adjusted in multiple directions according to the above angle adjustment steps to avoid the ship's magnetic field interference area as much as possible until magnetic compass 11 indicates accurately, thus completing self-error correction.

[0021] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
