Description

Technical Field

[0001] This utility model relates to the field of sensor installation device technology, and in particular to a device for measuring the installation level of equipment inside a borehole. Background Technology

[0002] In coal mining, stress monitoring of different coal seams and rock strata is often required. The common method is to install stress monitoring sensors in horizontal boreholes. When installing the sensors, it is necessary to keep the sensors themselves horizontal so that the force exerted when they are lowered is perpendicular to the sensor's support.

[0003] Typically, there is a horizontal structure on the sensor for mounting, and the mounting rod for pushing the sensor has a corresponding horizontal groove, which ensures that the sensor enters the final position in a horizontal orientation.

[0004] However, a significant drawback is that threaded structures are often used to extend the mounting rods for ease of installation. This results in the front horizontal structure not being able to maintain a precise level after multiple sections are installed. Even if each mounting rod has a level marking, the error between multiple mounting rods gradually accumulates due to the excessive length, and the twisting of the mounting rod material itself makes it impossible to guarantee the levelness of the front end. Therefore, it is necessary to design a device and method that can directly obtain the levelness of the front end.

[0005] Existing solutions include either installing an electronic attitude sensor, such as a gyroscope, inside the sensor, or placing the sensor at the front end of the mounting rod to save costs. Both methods require the use of electronic sensors and cables that run along the mounting rod, resulting in higher costs.

[0006] Therefore, a borehole equipment installation level measuring device is provided to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a drilling equipment installation level measuring device.

[0013] A light guide is fitted onto the mounting plate of the horizontal measuring head.

[0014] A flexible light guide is attached to the mounting plate, and the other end of the flexible light guide is connected to the light guide body.

[0015] A light-transmitting hole is provided on the mounting plate, and the light-transmitting hole is located directly below the horizontal measuring head;

[0016] Light-transmitting holes two and three are located at equal intervals on both sides of light-transmitting hole one, at an angle deviating from verticality;

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Example:

[0033] Reference Figure 1-5A drilling equipment installation level measuring device further includes: a mounting head 1, with a mounting cavity inside; a mounting plate 301 connected to the tail end of the mounting cavity inside the mounting head 1; a level measuring head 302 rotatably connected to the mounting plate 301; a light guide 4 sleeved on the level measuring head 302 and located on the mounting plate 301; a flexible light guide 5 connected to the mounting plate 301, with the other end of the flexible light guide 5 connected to the light guide 4; a light transmission hole 601 disposed on the mounting plate 301, located directly below the level measuring head 302; two light transmission holes 701 and three light transmission holes 801, located at equal intervals on both sides of the light transmission hole 601 at an angle deviating from vertical; and two flexible light guides 602, three flexible light guides 702, and four flexible light guides 802. 02, all are connected to the mounting plate 301. Flexible guide wire 2 602 is connected to light-transmitting hole 2 701, flexible guide wire 3 702 is connected to light-transmitting hole 3 801, and flexible guide wire 4 802 is connected to light-transmitting hole 3 801. A bearing 2 is fixedly connected inside the mounting plate 301. The horizontal measuring head 302 and the light guide body 4 are rotatably connected inside the bearing 2. The head of the mounting head 1 is provided with a horizontal groove for mounting the tail end of the sensor. The mounting head 1 is provided with a mounting groove. The mounting plate 301 is provided with a mounting protrusion that matches the mounting groove. Light-transmitting hole 2 701 and light-transmitting hole 3 801 are located at equal intervals on both sides of light-transmitting hole 1 601 at an angle of 30°-45° away from the vertical. A baffle 9 is fixedly connected to the mounting plate 301 at light-transmitting hole 2 701 and light-transmitting hole 3 801.

[0034] In this embodiment, light-transmitting holes 701 and 801 are set at equal intervals at an angle 30° away from vertical.

[0035] Firstly, a horizontal crossbar is designed at the tail end of the sensor, which corresponds to the horizontal groove designed at the front end of the mounting rod 1, making installation easier.

[0036] When in use, the light guide 4 is perpendicular to the ground under the action of gravity. During installation, the mounting head 1 is rotated, which in turn drives the light guide on the sensor and the mounting plate 301 to rotate synchronously.

[0037] The other end of the flexible light guide 5 is illuminated by a lighting device. Under different conditions, the light will be transmitted to the other end through the three holes, namely, light-transmitting hole 601, light-transmitting hole 701, and light-transmitting hole 801, and the corresponding flexible light guide. The horizontal measuring head 302 is used to block one of the light-transmitting holes.

[0038] The three sets of flexible light guides below can be made of different colors to easily distinguish different light-transmitting holes.

[0039] The baffle 9 is used to block the maximum movement distance of the horizontal measuring head 302 to avoid correction interference caused by excessive movement.

[0040] By observing whether the three different colored guide lights are lit, the angle of the mounting head 1 can be determined. The sensor is horizontally calibrated when the central light-transmitting hole 601, i.e. the flexible guide light 602, does not emit light.

[0041] At this point, pressure is applied to the sensor to cause it to expand and solidify, thus completing the installation.

[0042] This utility model is an installation rod device that does not use circuitry and utilizes the essential underground lighting lamp as the light signal input. The lighting device illuminates the other end of the flexible guide light 5. Under different conditions, the light will pass through three holes and the corresponding guide light to the other end. By observing whether the three flexible guide lights of different colors are lit, the angle of the installation head can be determined, thereby realizing the horizontal correction of the sensor.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
