Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of deep hole inclinometer, and particularly to a mine geological deep hole inclinometer. BACKGROUND

[0002] In mine geological exploration, deep hole inclinometer is one of the indispensable tools for accurately measuring the direction and inclination of the inside of the drill hole to provide important geological information. However, the inclinometer robot in the prior art has several technical problems in the operation process, which not only affects the service life of the equipment, but also reduces the accuracy and reliability of data transmission.

[0003] The working principle of the traditional inclinometer usually involves pre-placing the inclinometer tube in the deep hole, and then sending the inclinometer connected by the cable into the inclinometer tube for measurement. This process relies on a wire reel device to control the winding and unwinding of the cable, so that the inclinometer can automatically ascend and descend along the inner wall of the inclinometer tube to the specified depth position. Although this design can meet the measurement requirements to some extent, it has some shortcomings in actual application. First, since the cable needs to be guided through a series of guide rollers and uniformly wound on the wire reel, a moving block is required to reciprocate along the wire reel axis to ensure that the cable can be correctly guided and uniformly distributed. However, in this process, the part of the cable between the guide roller and the moving block will frequently experience bending stress. With the passage of time, this repeated bending action will cause damage to the wire core inside the cable, thereby affecting its physical integrity and electrical signal transmission performance. Especially for those applications that need to run stably for a long time, the risk of data transmission failure caused by mechanical wear is particularly significant.

[0004] Secondly, considering the fact that the cable rotates with the wire reel, in order to realize data transmission between the rotating part and the fixed control panel, a conductive slip ring must be used as an intermediary. Although the conductive slip ring can solve the problem of electrical connection between the rotating body and the stationary body under certain conditions, its working principle determines that it cannot completely avoid the friction loss between the brush and the surface of the slip ring. After long-term use, scratches will inevitably appear on the surface of the slip ring, and carbon powder particles will also adhere to it, which will seriously affect the contact quality between the slip ring and the brush, thereby interfering with the stability and accuracy of data transmission. SUMMARY

[0005] Therefore, the present application provides a mine geological deep hole inclinometer, which can overcome the shortcomings of the traditional inclinometer that the part of the cable between the guide roller and the moving block will frequently experience bending stress, which is easy to cause damage to the wire core, and the stability and accuracy of using a conductive slip ring as a data transmission intermediary are low.

When the rotating pressing plate 50 contacts the slope on the elastic hook plate 52, the rotating pressing plate 50 will squeeze the upper part of the elastic hook plate 52 to bend to the right to deform. When the rotating pressing plate 50 is separated from the elastic hook plate 52, the elastic hook plate 52 will restore to the original state and hook the top of the rotating pressing plate 50, so as to limit the rotating pressing plate 50. The rotating pressing plate 50 presses the sliding cover 48 to prevent the sliding cover 48 from moving with the cable 11 due to friction. After the protective shell 4 is installed back on the top of the bottom plate 3, under the sealing effect of the first rubber pad 47 and the second rubber pad 4801, water vapor can be prevented from entering the protective shell 4 to ensure that the components in the protective shell 4 can operate normally. When it is necessary to take out the inclinometer 1101 from the inclinometer tube 2, only the upper part of the elastic hook plate 52 is bent to the right to release the limitation of the rotating pressing plate 50. The torsional spring 51 will restore to the original state to drive the rotating pressing plate 50 to rotate upward to reset and separate from the sliding cover 48. Then the sliding cover 48 can be moved upward to separate from the inclinometer tube 2, and the inclinometer 1101 can be taken out from the inclinometer tube 2.

[0040] As Figure 14As shown, the device further comprises three conical sleeves 53, which are connected to the inner upper portion of the sliding cover 48 and are spaced apart from top to bottom, and the inner wall of the conical sleeve 53 is in contact with the surface of the cable 11; when the winding disc 10 rotates to wind or unwind the cable 11, the conical sleeve 53 can scrape off the impurities and moisture adhered to the surface of the cable 11 downward, preventing the cable 11 from bringing the impurities and moisture into the protective shell 4.

[0041] As shown, Figure 7 As shown, the device further comprises an elastic rope 54, which is connected between the third wire 27 and the controller 12; when the sliding seat 9 moves back and forth, the joint 26 will gradually move close to or away from the controller 12, causing the third wire 27 to move randomly, and under the pulling force of the elastic rope 54, the third wire 27 can always move close to the controller 12, preventing the third wire 27 from falling on the guide rail 8 and affecting the movement of the sliding seat 9.

[0042] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
