Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drilling equipment, in particular to a self-storage type borehole imager probe. Background Technique
[0002] In the existing ground geological exploration, generally, the method of drilling first and then exploring the hole is adopted, that is, the formation is first opened, and then a borehole imager is used for detection.
[0003] Most of the existing borehole imagers are wired, which are composed of a probe, a cable length measuring device and a mainframe. When in use, the probe needs to be connected to the cable, and then the probe is pushed into the hole by a push rod. A cable length measuring device and a mainframe are placed at the hole opening. The cable length measuring device is mainly used to measure the depth of the pushed cable. The battery pack in the mainframe provides power for the probe and the cable length measuring device. The mainframe can display the video and images inside the borehole in real time. By displaying the video and images and combining the cable length measuring device, geological information such as rock formations and pores in the hole can be judged, providing a basis for hole opening and drawing geological maps.
[0004] Since the wired borehole imager needs cable connection, cable maintenance and management are often required, resulting in high use costs. On the other hand, the cable bears tensile force, and its service life will be greatly reduced. Once the cable is damaged, the instrument will not be able to work continuously. Moreover, signals are transmitted between the probe and the mainframe through the cable, and this part of the signal will be affected by noise. When the signal cannot be received, the probe tube needs to be withdrawn from the hole to check the cable quality, reducing the observation accuracy and use effect.
[0005] Therefore, it is necessary to provide a self-storage type borehole imager probe to solve the above technical problems. Content of the Utility Model
[0006] The utility model provides a self-storage type borehole imager probe, which solves the problems of high use cost, short service life, reduced observation accuracy and use effect.

[0027] The present utility model will be further described below in conjunction with the drawings and embodiments
[0028] First embodiment

A self - storage type borehole imager probe includes: a circuit outer tube 3
[0030] A lower joint 5, one end of the outer side surface of the lower joint 5 is arranged at one end of the inner side surface of the circuit outer tube 3, and the other end of the inner side surface of the lower joint 5 is provided with an aviation plug 10
[0031] A circuit skeleton 4, one end of the outer side surface of the circuit skeleton 4 is arranged at the other end of the inner side surface of the circuit outer tube 3
[0032] An end cap 1, the end cap 1 is arranged at the other end of the outer side surface of the circuit skeleton 4, an optical glass 7 is arranged on the inner side surface of the end cap 1, and a circlip for hole 6 is arranged on the outer side surface of the optical glass 7
[0033] Two centralizers 2 are respectively sleeved on the outer sides of the lower joint 5 of the circuit framework 4.
[0034] A plurality of countersunk head screws 9 are arranged inside the side surface of the end cover 1, and one ends of the plurality of countersunk head screws 9 are all threadedly connected to the inside of the side surface of the circuit framework 4.
[0035] A plurality of socket head cap screws 8 are arranged inside the side surfaces of the two centralizers 2, and one ends of the plurality of socket head cap screws 8 are respectively threadedly connected to the inside of the side surface of the circuit framework 4 and the inside of the side surface of the lower joint 5.
[0036] The end cover 1 of this instrument is connected by countersunk head screws 9. The circumferentially evenly arranged countersunk head screws 9 are used to limit the circumferential movement of the end cover, avoiding the problem of lead looping. Moreover, the circuit framework 4 and the battery compartment of the original instrument are designed separately, and there is also lead looping between the circuit framework 4 and the battery. This instrument combines the circuit framework 4 and the battery compartment into one body, and the leads between the power supply and the circuit board will not be affected at all. Finally, the original instrument uses the form of lowering a cable to extend the probe into the hole, while this instrument uses a self-storage method to store the detected information in the storage device inside the instrument. First, drill a hole and then explore the hole. After exploring the hole, take out the instrument and then export the data for processing, avoiding incomplete or unobtainable transmission data due to cable wear.
[0037] Through the arrangement of the centralizer 2, when in use, the inclination of the outer circuit tube 3 can be avoided.
[0038] The working principle of a self-storage type borehole imager probe provided by the present utility model is as follows:
[0039] First, install the centralizer 2 into the circuit framework 4 and align it with the positioning hole and fix it with socket head cap screws 8. Install the optical glass 7 at the middle hole position of the end cover 1, and press the optical glass 7 tightly with a hole retaining snap ring 6. Then install the whole end cover 1 into the circuit framework 4 and fix it with countersunk head screws 9. Then connect one end of the circuit framework 4 and the outer circuit tube 3 by thread, and connect the other end of the outer circuit tube 3 to the lower joint 5 by thread fit as well. Finally, install the centralizer 2 into the lower joint 5 and align it with the positioning hole and fix it with socket head cap screws 8, and install the aviation plug 10 on the designated end surface of the lower joint 5 to complete all the assembly work of the instrument.
[0040] Compared with the related technology, a self-storage type borehole imager probe provided by the present utility model has the following beneficial effects:
[0041] Through the cooperation of structures such as the end cap 1, the centralizer 2, the outer circuit tube 3, the circuit skeleton 4, and the lower joint 5, during use, the probe is lowered into the hole by the drill pipe. After the camera has captured all the images, the drill pipe then withdraws the probe, and all data collection can be completed on the ground. This avoids the situation where the cable connection is prone to wear. In this way, not only the usage cost is reduced, but also the situation where the service life is reduced due to the exposure of the cable can be avoided. At the same time, long-distance cable data transmission can be avoided, thereby increasing the accuracy and usage effect of the observation.

The second embodiment is merely a preferred manner of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.
[0044] Specifically, the difference of a self-storing borehole imager probe provided in the second embodiment of the present application is that, for a self-storing borehole imager probe, the centralizer 2 includes a fixing sleeve 21, a plurality of centralizing blocks 22, grooves 23, mounting screws 24, rotating grooves 25, and rollers 26.

[0046] The rotating grooves 25 are respectively opened inside both ends of the sides of the plurality of centralizing blocks 22, and the rollers 26 are rotatably connected to the inner side surfaces of the rotating grooves 25.
[0047] The rotating groove 25 is arranged on the side of the groove 23.
[0048] After long-term use, when one of the rollers 26 is damaged, the user can rotate and install the mounting screw 24 on the centralizing block 22 of the roller 26 to make the mounting screw 24 withdraw from the inside of the fixing sleeve 21 and the centralizing block 22, and then replace the centralizing block 22. In this way, it is not necessary to replace the entire centralizing block 22, thereby reducing the usage cost.
[0049] The working principle of a self-storing borehole imager probe provided by the present utility model is as follows:
[0050] When in use, the fixing sleeve 21 is sleeved on the outer sides of the circuit skeleton 4 and the lower joint 5, and then fixed by the hexagon socket head cap screw 8. When subsequently placed into the detection hole, the roller 26 can support the centering block 22 and roll on the inner wall of the hole, avoiding direct friction between the centering block 22 and the inner wall of the hole wall, and increasing the service life of the centralizer 2.
