In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Please refer to Figure 1-4As shown, a fixing device for a wireless downhole inclinometer comprises a support frame 1 and a bottom support foot seat 2 installed at the bottom end of the support frame 1. The bottom support foot seat 2 is a cross structure. The bottom support foot seat 2 of the cross structure has good stable supporting performance and can play a stable supporting role.

[0025] An angle calibration mechanism is installed at the top of the support frame 1, and the angle calibration mechanism includes a central axis 3 installed at the top of the support frame 1, a first angle plate 4 installed at the front end of the support frame 1 with the central axis 3 as the axis, and a second angle plate 5 installed at the rear end of the support frame 1 with the central axis 3 as the axis. A first pointer 6 opposite to the first angle plate 4 is installed at one end of the shaft of the central axis 3, and a second pointer 13 opposite to the second angle plate 5 is installed at the other end of the shaft of the second angle plate 5, and an arm truss 7 supporting the clamping tool 8 is installed at the tail end of the second pointer 13. The tail ends of the arms of the first pointer 6 and the second pointer 13 are both provided with a rotation angle with the central axis 3. The connected bearing sleeve, after the fixing device is placed in the specified position, when the road surface is uneven, the first pointer 6, under the action of the vertical centripetal force, always points vertically to the ground, and deviates from the 90° angle of the first angle disk 4. The angle between the two is the inclination angle of the fixing device. Then, according to the angle deviation between the two, the second pointer 13 is pushed to swing, so that it deflects along the 90° angle of the second angle disk 5, and rotates at the same angle as the 90° deviation angle between the first pointer 6 and the first angle disk 4. The arm truss 7 is horizontally calibrated with the central axis 3 as the axis center, and the clamping tooling 8 at both ends of its bracket is horizontally aligned to serve as a horizontal mounting platform for the wireless drilling inclinometer.

[0026] The plate surface of the second angle disk 5 is provided with a first guide rail 9 and a second guide rail 10 which are slidably connected to the second pointer 13 in sequence from the inside to the outside with its center. The front end of the arm of the second pointer 13 is screwed with a first knob bolt 11 which is opposite to the first guide rail 9, and the front end of the arm of the second pointer 13 is screwed with a second knob bolt 12 which is opposite to the second guide rail 10. When the second pointer 13 is pushed to rotate around the central axis 3, the annular track guidance of the first guide rail 9 and the second guide rail 10 can improve the swinging stability of the second pointer 13. After the second pointer 13 is swung and calibrated, the first knob bolt 11 and the second knob bolt 12 are tightened in sequence, and the locking friction force thereof can be used to fix the calibration position of the second pointer 13.

[0027] Both ends of the bracket of the angle calibration mechanism are equipped with a clamping tool 8, which includes a track frame 81. The inside of the bracket of the track frame 81 is provided with a clamping screw rod 82 and a clamping guide rail 83 from top to bottom, and the outer side of the shaft rod of the clamping screw rod 82 is symmetrically sleeved with a clamping slide 84 guided by the clamping guide rail 83, and the upper ends of the two sets of clamping slides 84 are symmetrically provided with a clamping sleeve 85, and the clamping screw rod 82 is bounded by the midline, and the two sides of the midline are symmetrically provided with clamping slides 84. With the matched positive and negative threads, after the horizontal calibration of the fixing device, the wireless drilling inclinometer is placed between the clamping sleeves 85 of the clamping fixture 8, and then the driving hand wheel 86 is rotated in turn to drive the clamping screw rod 82 to rotate, and the positive and negative threads on the clamping screw rod 82 are used to push the two sets of clamping slides 84 to slide symmetrically along the track direction of the clamping guide rail 83, so that the two sets of clamping sleeves 85 are clamped, and the two ends of the wireless drilling inclinometer are clamped and fixed in turn, so that the wireless drilling inclinometer can be horizontally fixed and limited to carry out measurement work.

[0028] The working principle of the utility model is as follows: when the wireless drilling inclinometer is fixedly supported by the fixing device, the fixing device is placed upright at a designated position by using a combination of a support stand 1 and a bottom support foot seat 2. After the placement is completed, when the road surface is uneven, the first pointer 6 will always point vertically to the ground under the action of the vertical centripetal force, and deviate from the 90° angle of the first angle disk 4. The angle between the two is the inclination angle of the fixing device on the uneven road surface. Then, according to the angle deviation angle between the two, the second pointer 13 is pushed to swing, so that it deflects along the 90° angle of the second angle disk 5, and rotates the same angle as the 90° deviation angle between the first pointer 6 and the first angle disk 4, so as to move the arm beam upward. The frame 7 is horizontally calibrated with the central axis 3 as the axis center, and the fixing clamping tools 8 at both ends of the bracket are horizontally aligned to serve as a horizontal mounting platform for the wireless while drilling inclinometer. The wireless while drilling inclinometer is then placed between the clamping sleeves 85 of the fixing clamping tool 8, and then the driving hand wheel 86 is rotated in turn to drive the clamping screw rod 82 to rotate. The positive and negative threads on the clamping screw rod 82 are used to push the two groups of clamping slides 84 to slide symmetrically along the track direction of the clamping guide rail 83, so that the two groups of clamping sleeves 85 are clamped, and the two ends of the wireless while drilling inclinometer are clamped and fixed in turn, so that the wireless while drilling inclinometer can be horizontally fixed and limited to carry out measurement work. The overall operation is simple and convenient, and the flexible use is better. After use, it is easy to carry and move.
