In existing testing devices, the sensors and circuit boards are fixed to a non-rotating base, making it impossible to test under rotating conditions and reproduce the effects of rotational centrifugal force, resulting in inaccurate test results.

[0010] In a preferred embodiment, a pad is provided between the fluxgate and the square mounting groove, and the fluxgate is fixed to the fluxgate mounting part by bolts.

[0011] In a preferred embodiment, the circuit board mounting section is provided with a plate-like structure, and the power board and the main control board are respectively mounted on both sides of the plate-like structure by bolts.

[0012] In a preferred embodiment, the gauge frame is provided with three circular mounting slots, and the three gauges are respectively installed in the three circular mounting slots, and the three gauges are respectively distributed along the X-axis, Y-axis and Z-axis of the coordinate system.

The gauge in the Z-axis direction is installed in a circular mounting groove by a positioning sleeve, and the positioning sleeve is provided with a threaded pressure ring for pressing the positioning sleeve at a relative position.

[0014] The beneficial effects of the technical solution in this application are:

[0015] This solution enables modular installation of the fluxgate, meter, and circuit board through the installation structure, while also facilitating disassembly and assembly. The installation structure can be installed as a whole on the rotating device to perform performance tests on the above components in a rotating state, resulting in more accurate test results compared to tests conducted under non-rotating conditions.

Embodiments of the present invention

[0022] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present application are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present application to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present application, and to enable those skilled in the art to understand the present application and design various embodiments with various modifications suitable for a particular purpose.

[0023] As shown in Figures 1-5, the technical solution of this application provides an installation structure for testing the hardware functions of a rotary guide system. This installation structure can achieve integrated installation of the gauge 16, fluxgate 7, power board 9, and main control board 10. Through a sealed rotating environment, after the components are installed, the installation structure can be installed on the rotating device and tested in a rotating state to preliminarily verify the basic functions and reliability of the hardware circuit and sensors.

[0024] The installation structure of this solution includes a sleeve 1, a circuit frame located inside the sleeve 1, a meter mounting frame 11 detachably connected to the circuit frame, and plugs 2 and 3 at both ends of the sleeve 1. Plugs 2 and 3 are respectively inserted into the two ends of the sleeve 1 and threadedly connected to the sleeve 1. After installation, plugs 2 and 3 respectively press against the circuit frame and the meter mounting frame 11. The circuit frame includes an integrally formed fluxgate mounting part 4 and a circuit board mounting part 5. The fluxgate 7 is embedded in the fluxgate mounting part 4, and the meter 16 is embedded in the meter mounting frame 11.

[0025] In the above scheme, after the fluxgate 7, the meter 16 box, and the circuit board are installed in their corresponding positions, the sleeve 1 is fitted over the entire connection between the circuit frame and the meter frame 11. Then, the internal space of the sleeve 1 is sealed by the plug 2 and the plug 3, while simultaneously limiting the connection between the circuit frame and the meter frame 11. This structure facilitates the assembly and disassembly of the entire frame and ensures that the frame structure does not shift during rotation.

[0026] The fluxgate mounting part 4 is provided with three square mounting slots 6, and three fluxgates 7 are respectively installed in the three square mounting slots 6, with the three fluxgates 7 axially distributed along the X-axis, Y-axis, and Z-axis of the coordinate system, where the Z-axis is the axial direction of the sleeve 1. A spacer 8 is provided between the fluxgate 7 and the square mounting slot 6, and the fluxgate 7 is fixed to the fluxgate mounting part 4 with bolts. During installation, the fluxgate 7 is inserted into the fluxgate mounting part 4, and then screws are passed through the mounting holes of the fluxgate 7 to secure it in the square mounting slot 6. Next, set screws are used to press the fluxgate 7 against the side wall of the square mounting slot 6 to prevent it from loosening. The remaining two fluxgates 7 are installed in the same way. The circuit frame is made of a non-magnetic material, such as aluminum alloy, to avoid interference with the fluxgates 7.

[0027] The circuit board mounting section 5 has a plate-like structure, and the power supply board 9 and the main control board 10 are respectively mounted on both sides of the plate-like structure with bolts. There is a certain distance between the power supply board and the main control board and the fluxgate 7 to avoid interference with the fluxgate 7.

[0028] The gauge frame 11 has three circular mounting slots 12, and three gauges 16 are respectively installed in the three circular mounting slots 12, with the three gauges 16 axially distributed along the X-axis, Y-axis, and Z-axis of the coordinate system. The gauges 16 in the X-axis and Y-axis directions are limited by pressure caps 13, which are fixed to the gauges 16 by bolts. The gauges 16 in the Z-axis direction are installed in the circular mounting slots 12 by positioning sleeves 14, with threaded pressure rings 15 positioned opposite to the positioning sleeves 14 for pressing them.

[0029] The gauge frame 11 is mounted on the circuit frame. Pressure caps 13 are fitted onto the gauge 16 in the X and Y axes to limit its movement, and then tightened by four peripheral screws. The gauge 16 in the Z-axis direction (i.e., the axial direction of the sleeve 1) is first positioned by a positioning sleeve 14. A protrusion on the positioning sleeve 14 engages with a corresponding groove on the gauge 16. Then, a threaded pressure ring 15 presses against the positioning sleeve 14 to tighten the gauge 16, preventing it from loosening or shifting during axial rotation.

[0030] Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art and related fields without creative effort should fall within the scope of protection of this application.
