All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] In the above description of this utility model, it should be noted that the terms "one side," "the other side," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0032] Please see Figures 1-6This utility model provides a technical solution: an inclination measuring device for mineral geological exploration, comprising a base plate 1, a connecting plate 2, a protractor 3, a pointer 4, a first counterweight 51, and a second counterweight 52. The connecting plate 2 is arranged perpendicular to the base plate 1 and is rotatably connected to the base plate 1. The rotation center line of the connecting plate 2 is perpendicular to the base plate 1. The protractor 3 and the first counterweight 51 are both fixedly connected to the connecting plate 2. The center of gravity of the combined structure of the protractor 3, the first counterweight 51, and the connecting plate 2 is located on one side of the rotation center line of the connecting plate 2. The protractor 3 is arranged perpendicular to the base plate 1. One end of the pointer 4 is rotatably connected to the center position of the protractor 3. The second counterweight 52 is fixedly connected to the one end of the pointer 4.

[0033] Before using the tilt measuring device for mineral geological exploration described in this utility model to measure the tilt angle of a mountain surface, the tilt measuring device for mineral geological exploration described in this utility model is first placed on a horizontal surface. Since one end of the pointer 4 is rotatably connected to the center of the protractor 3, and the second counterweight 52 is fixedly connected to the one end of the pointer 4, the pointer 4 rotates around the center of the protractor 3 under the action of the gravity of the second counterweight 52. When the second counterweight 52 stops rotating, since the second counterweight 52 is always kept downward due to its own weight, the pointer 4 can be kept vertically upward. At this time, the reading of the position of the scale line of the protractor 3 pointed to by the pointer 4 is taken as the first scale value.

[0034] When using the tilt measuring device for mineral geological exploration described in this utility model to measure the tilt angle of a mountain surface, the lower surface of the base plate 1 is first brought into contact with the mountain surface. Since the connecting plate 2 is rotatably connected to the base plate 1, the rotation center line of the connecting plate 2 is perpendicular to the base plate 1. The protractor 3 and the first counterweight 51 are both fixedly connected to the connecting plate 2. The combined structure of the protractor 3, the first counterweight 51 and the connecting plate 2 can rotate with the rotation center line of the connecting plate 2 as the rotation center. Since the center of gravity of the combined structure of the protractor 3, the first counterweight 51 and the connecting plate 2 is located on one side of the rotation center line of the connecting plate 2, the side where the center of gravity of the combined structure of the protractor 3, the first counterweight 51 and the connecting plate 2 is located will rotate to the lower side of the rotation center line of the connecting plate 2, so that the scale surface of the protractor 3 of the tilt measuring device for mineral geological exploration described in this utility model can automatically rotate to a state close to vertical. The scale surface of the protractor 3 is the side of the protractor 3 with the scale printed on it.

[0035] When the combined structure of the protractor 3, the first counterweight 51, and the connecting plate 2 rotates around the rotation center line of the connecting plate 2, the pointer 4 also rotates under the gravity of the second counterweight 52 until the combined structure of the protractor 3, the first counterweight 51, and the connecting plate 2 stops rotating. The second counterweight 52, under its own gravity, drives the pointer 4 to gradually stop rotating. After the second counterweight 52 stops rotating, the pointer 4 is in a vertically upward state. At this time, the reading of the position of the scale line of the protractor 3 pointed to by the pointer 4 is the second scale value. The difference between the first scale value and the second scale value is the inclination angle of the mountain surface. At this time, the inclination angle measurement of the mountain surface by the inclination angle measurement device for mineral geological exploration described in this utility model is completed.

[0036] When using the tilt measuring device for mineral geological exploration described in this utility model to measure the tilt angle of a mountain surface, the protractor 3 can automatically rotate to a near-vertical state, which can more accurately reflect the actual tilt angle of the mountain surface to a certain extent.

[0037] In this embodiment, the center lines of the connecting plate 2 and the protractor 3 are both located on the rotation center line of the connecting plate 2. The upper end of the connecting plate 2 is fixed to the lower end of the protractor 3. The first counterweight 51 is fixed to the lower part of one end of the connecting plate 2. The center of gravity of the combined structure of the protractor 3, the first counterweight 51 and the connecting plate 2 is located between the rotation center line of the connecting plate 2 and the first counterweight 51.

[0038] In this embodiment: the upper surface of the base plate 1 is recessed downward to form a first rotating groove; it also includes a rotating rod 6, which is arranged along the rotation center line of the connecting plate 2. The lower end of the rotating rod 6 is located in the first rotating groove, and the lower end of the rotating rod 6 is rotatably engaged with the first rotating groove. The upper end of the rotating rod 6 is fixedly connected to the lower end of the connecting plate 2. With this structure, the connecting plate 2 can be rotatably connected to the base plate 1.

[0039] In this embodiment: the lower part of the side wall of the first rotating groove is recessed inward to form a first limiting groove; it also includes a first limiting ring 71, the first limiting ring 71 is fixed to the lower end of the rotating rod 6, the first limiting ring 71 is located in the first limiting groove, and the first limiting ring 71 cooperates with the first limiting groove.

[0040] When the rotating rod 6 drives the first limiting ring 71 to rotate, the first limiting ring 71 will not move upward and disengage from the first limiting groove because it is supported by the top wall of the first limiting groove. Thus, the rotating rod 6 will not disengage from the first rotating groove during rotation. With this structure, the connecting plate 2 will not disengage from the base plate 1 during rotation.

[0041] In this embodiment: one end of the pointer 4 is recessed inward toward the side of the protractor 3 to form a second rotating groove; it also includes a rotating shaft 8, which is fixed to the center of the protractor 3. The end of the rotating shaft 8 away from the protractor 3 is located in the second rotating groove. The rotating shaft 8 cooperates with the second rotating groove. With this structure, one end of the pointer 4 can be rotatably connected to the center position of the protractor 3.

[0042] In this embodiment: the groove wall of the second rotating groove opposite to the end of the protractor 3 is recessed inward to form a second limiting groove; it also includes a second limiting ring 72, the second limiting ring 72 is fixed to the end of the rotating shaft 8 opposite to the protractor 3, the second limiting ring 72 is located in the second limiting groove, and the second limiting ring 72 cooperates with the second limiting groove.

[0043] When the pointer 4 rotates, it drives the second rotating groove and the second limiting groove to rotate. Since the second limiting ring 72 is located in the second limiting groove, the second limiting ring 72 is rotatably engaged with the second limiting groove. The side wall of the second limiting groove is supported by the end face of the second limiting ring 72. The second limiting ring 72 will not move away from the second limiting groove along the length direction of the rotating shaft 8, so that the pointer 4 will not leave the rotating shaft 8 during rotation. With this structure, the pointer 4 will not leave the center position of the protractor 3 during rotation.

[0044] In this embodiment: the upper end of the rotating rod 6 protrudes from the upper surface of the base plate 1, and the lower surface of the first counterweight 51 is recessed inward to form a rolling groove; it also includes a ball bearing 9, which rolls and engages in the rolling groove, and the ball bearing 9 abuts against the upper surface of the base plate 1. With this structure, the friction between the first counterweight 51 and the base plate 1 is changed from sliding friction to rolling friction, thereby reducing the friction experienced by the first counterweight 51 during rotation. To a certain extent, this allows the combined structure of the protractor 3, the first counterweight 51, and the connecting plate 2 of the tilt measuring device for mineral geological exploration described in this utility model to rotate more smoothly.

[0045] In this embodiment: the lower surface of the base plate 1 is provided with a plurality of anti-slip nails 10, which can be inserted into the lower part of the mountain surface. When using the tilt measuring device for mineral geological exploration of the present invention to measure the tilt angle of the mountain surface, the possibility of the tilt measuring device for mineral geological exploration of the present invention sliding down the slope of the mountain is reduced to a certain extent.

[0046] In this embodiment, a scraper 11 and a spring 14 are also included. The scraper 11 is arranged parallel to the base plate 1. The scraper 11 has a plurality of through holes 15. A plurality of anti-slip studs 10 are fitted into the plurality of through holes 15. One end of the spring 14 is fixed to the base plate 1, and the other end of the spring 14 is fixed to the scraper 11.

[0047] After the anti-slip nails 10 are pulled out from the lower part of the mountain surface, the scraper 11 is pushed in the direction away from the base plate 1. The spring 14 extends under the pulling force of the scraper 11, so that the through hole 15 slides relative to the anti-slip nails 10. At this time, the scraper 11 moves towards the lower end of the anti-slip nails 10 along the length direction of the anti-slip nails 10, so that the scraper 11 scrapes away the mud adhering between the anti-slip nails 10, so that mud does not easily accumulate between the multiple anti-slip nails 10. When the scraper 11 is stopped, the spring 14 shortens because it is no longer pulled by the scraper 11. The scraper 11 will move towards the upper part of the anti-slip nails 10 under the pulling force of the spring 14 until the scraper 11 returns to the position of the upper part of the anti-slip nails 10. With this structure, the possibility of the anti-slip effect of the anti-slip nails 10 deteriorating due to the accumulation of mud between the anti-slip nails 10 can be reduced to a certain extent.

[0048] In this embodiment, a glass windproof cover 16 is also included. The combined structure of the protractor 3, the first counterweight 51, and the connecting plate 2 is located inside the glass windproof cover 16. The glass windproof cover 16 is detachably connected to the base plate 1. With this structure, when the tilt measuring device for mineral geological exploration described in this utility model measures the tilt angle of the mountain surface, the combined structure of the protractor 3, the first counterweight 51, and the connecting plate 2 can swing without the action of wind, which improves the measurement speed to a certain extent.

[0049] In this embodiment: the glass windproof cover 16 has a cylindrical structure that is closed at the top and open at the bottom, and the lower end of the glass windproof cover 16 has an internal thread 13; it also includes a ring 17, the combined structure of the protractor 3, the first counterweight 51 and the connecting plate 2 is located inside the ring 17, the lower end of the ring 17 is fixed to the base plate 1, the outer circumferential surface of the ring 17 has an external thread 12, and the glass windproof cover 16 is threadedly connected to the ring 17. With this structure, the glass windproof cover 16 can be detachably connected to the base plate 1.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
