[0002] During the inclination measurement of boreholes, rollers are added to the surface of the inclinometer rod to facilitate its movement within the hole. However, due to the different borehole diameters in the actual inclinometer measurement process, the rollers on the inclinometer rod are not easy to disassemble and replace, and the distance between the rollers and the inclinometer rod is fixed, which reduces the scope of application. Summary of the Invention

[0003] In view of this, the present invention aims to propose a drilling inclinometer device to solve the technical problem that in the actual inclinometer process, the apertures of the boreholes are different, the rollers on the inclinometer rod are inconvenient to disassemble and replace, and the distance between the rollers and the inclinometer rod is fixed, which reduces the scope of application.

[0004] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0005] A drilling inclinometer device includes an inclinometer rod having a cavity therein, mounting cavities on both sides of the inclinometer rod, a connecting plate fixedly connected to the mounting cavity, two clamping seats fixedly connected to the side walls of the connecting plate, and a clamping groove on each of the two clamping seats;

[0006] A connecting seat is provided between the two connecting seats on the same connecting plate. The connecting seat has an inner cavity. Both ends of the inner cavity are plugged with connecting pins. A supporting spring is fixedly connected between the connecting pin and the inner wall of the inner cavity. The two connecting pins in the same inner cavity pass through the connecting seat and are respectively plugged into the two connecting grooves. A supporting wheel is rotatably connected to the surface of the connecting seat.

[0007] Furthermore, a support frame is fixedly mounted on the surface of the connecting plate, and an end of the support frame is rotatably connected to the support wheel.

[0008] Furthermore, a docking body is fixedly connected to the side wall of the connecting plate, and a docking port adapted to the docking body is provided on the connecting seat.

[0009] Furthermore, two paving slots are provided on the surface of the connecting seat, and a toggle block is slidably provided in the two paving slots, and the two toggle blocks are fixedly connected to the two locking pins respectively.

[0010] Furthermore, both ends of the inclinometer rod are threadedly connected to connectors, and the ends of the connectors are provided with hanging rings.

[0011] Furthermore, a connecting groove is provided at the end of the connecting head, a connecting shaft is movably connected in the connecting groove, and the end of the connecting shaft is fixedly connected to the hanging ring.

[0012] Compared with the prior art, the drilling inclination measuring device described in the present invention has the following advantages:

[0013] According to the present invention, before measuring the inclination of the borehole, components with different spacings between the support wheel and the connecting seat can be prepared in advance. According to the aperture size of the borehole, the components with the spacing between the optional support wheel and the connecting seat are installed first. During the installation process, the two snap pins are respectively inserted into the snap grooves of the snap seat to achieve the installation of the adapted support wheel to adapt to the aperture of the borehole.

[0014] The present invention achieves position limiting of the connecting seat by plugging the docking body and the docking port, thereby preventing the connecting seat from moving between the two clamping seats.

[0015] When the connecting seat needs to be disassembled, the toggle block is pushed, and the toggle block drives the clamping pin to move, thereby retracting the clamping pin into the connecting seat, canceling the connection between the clamping pin and the clamping groove on the connecting seat, and facilitating the disassembly and assembly of the connecting seat.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0030] like Figures 1 to 7As shown, in one embodiment, a drilling inclinometer includes an inclinometer rod 1 having a cavity therein. Mounting cavities 2 are provided on both sides of the inclinometer rod 1. A connecting plate 3 is fixedly connected to the mounting cavity 2. Two clamping seats 4 are fixedly connected to the side walls of the connecting plate 3. Both clamping seats 4 have a clamping groove 5.

[0031] A connecting seat 6 is provided between the two connecting seats 4 on the same connecting plate 3. The connecting seat 6 has an inner cavity 601. Connecting pins 7 are inserted at both ends of the inner cavity 601. A supporting spring 8 is fixedly connected between the connecting pins 7 and the inner wall of the inner cavity 601. The two connecting pins 7 in the same inner cavity 601 pass through the connecting seat 6 and are respectively inserted into the two connecting grooves 5.

[0032] A support wheel 9 is rotatably connected to the surface of the connecting seat 6 .

[0033] Specifically, a support frame 10 is fixedly mounted on the surface of the connecting plate 3, the end of which is rotatably connected to the support wheel 9. A wire inlet 11 is provided on the side wall of the inclinometer rod 1, and both the top outer edge and the bottom inner edge of the wire inlet 11 are provided with curved surfaces 1101. It should be understood that the cavity within the inclinometer rod 1 is used to accommodate a probe, specifically a tilt sensor. The wire inlet 11 is used to pass the probe's external wires. By providing the curved surface 1101 at the wire inlet 11, damage to the wires caused by scraping from the edge of the wire inlet 11 is reduced.

[0034] It should be understood that before measuring the inclination of the borehole, components with different spacings between the support wheel 9 and the connecting seat 6 can be prepared in advance. According to the size of the borehole, the component with the spacing between the selected support wheel 9 and the connecting seat 6 is first installed. During the installation process, the two clamping pins 7 are respectively inserted into the clamping grooves 5 of the clamping seat 4 to achieve the installation of the adapted support wheel 9 to adapt to the borehole diameter;

[0035] When the supporting wheel 9 needs to be disassembled, the connecting seat 6 can be taken out from between the two connecting seats 4 by pushing the connecting pin 7 out of the connecting slot 5 to achieve disassembly.

[0036] like Figure 6 and Figure 7 As shown, in one embodiment, a docking body 12 is fixedly connected to the side wall of the connecting plate 3, and a docking port 13 is formed on the connecting seat 6 to adapt to the docking body 12. It should be understood that the connection between the docking body 12 and the docking port 13 is used to limit the position of the connecting seat 6, thereby preventing the connecting seat 6 from moving between the two clamping seats 4.

[0037] like Figure 7As shown, in one embodiment, two clearance notches 14 are provided on the surface of the connecting base 6, and a toggle block 15 is slidably disposed within the two clearance notches 14. The two toggle blocks 15 are respectively fixedly connected to the two engaging pins 7. It should be understood that when the connecting base 6 needs to be disassembled, the toggle block 15 is pushed, and the toggle block 15 drives the engaging pins 7 to move, thereby retracting the engaging pins 7 into the connecting base 6, canceling the connection between the engaging pins 7 and the engaging slots 5 on the engaging base 4, and facilitating the disassembly and assembly of the connecting base 6.

[0038] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, in one embodiment, both ends of the inclinometer rod 1 are threadedly connected to connectors 16, and the ends of the connectors 16 are provided with hanging rings 17. It should be understood that the threaded connection between the connectors 16 and the top of the inclinometer rod 1 achieves detachability. After the connectors 16 are removed, the top of the inclinometer rod 1 can be opened, allowing the probe to be inserted into the cavity on the inner wall of the inclinometer rod 1 through the opening at the top of the inclinometer rod 1. The wire can then be passed through the wire inlet 11 and tied to the hanging ring 17 with a rope, thereby facilitating the positioning of the wire.

[0039] like Figure 5 As shown, in one embodiment, a connecting groove 18 is formed at the end of the connecting head 16, and a connecting shaft 19 is movably connected to the connecting groove 18. The end of the connecting shaft 19 is fixedly connected to the hanging ring 17. It should be understood that the movable connection between the connecting groove 18 and the connecting shaft 19 enables the angle of the hanging ring 17 to be adjustable, which facilitates the operator to adjust the angle according to actual needs.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
