[0001] This utility model belongs to the field of borehole detection equipment technology, and in particular relates to an image acquisition device for quantifying the clarity of borehole detection equipment. Background Technology

Therefore, quantifying the clarity and illumination of borescopes has become a pressing problem in this field. Utility Model Content

Before testing the borehole probing equipment, the operator can install the illuminance meter light sensor inside the detection hole, the test card into the detection slot, and the borehole probing equipment probe into the focal length limiting component.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] An image acquisition device for quantifying the sharpness of borehole probes, the structure of which can be made of Figures 1-7 The following is an illustration. In this embodiment, the image acquisition device for quantifying the sharpness of a borehole probe includes: a support 1, a mounting base 2, and a focal length limiting component. The support 1 provides an assembly base for the focal length limiting component and the mounting base 2, and accommodates the probe of the borehole probe to be tested. The mounting base 2 accommodates the testing equipment and can be adjusted in position according to the actual testing steps. The focal length limiting component adjusts the position of the borehole probe inside the device so as to meet the focal length requirements of the borehole probe when testing it.

[0034] Specifically, the support base 1 has a receiving hole 11, and a connecting shaft 12 is provided on the top surface of the support base 1, with the axial direction of the connecting shaft 12 parallel to the axial direction of the receiving hole 11. The mounting base 2 is rotatably connected to the connecting shaft 12, and the bottom surface of the mounting base 2 is in contact with the top surface of the support base 1. The mounting base 2 has a detection groove and a detection hole 21, wherein the axial direction of the detection hole 21 is parallel to the axial direction of the connecting shaft 12, and the detection groove is provided on the bottom surface of the mounting base 2, with the detection groove and detection hole 21 located on opposite sides of the connecting shaft 12. The focal length limiting assembly includes an adjusting sleeve 3 and a connecting member 4, wherein the adjusting sleeve 3 is disposed inside the receiving hole 11, and the connecting member 4 is adjustablely disposed inside the adjusting sleeve 3, and has an assembly hole on the connecting member 4.

[0035] During use, the operator inserts the test card 61 into the detection slot, the illuminance meter light sensor 62 into the detection hole 21, and the probe of the borehole probe to be tested into the mounting hole on the connector 4. Then, according to the focal length requirements of the borehole probe, the position of the connector 4 inside the adjusting sleeve 3 is adjusted. When testing the illumination brightness of the borehole probe, the operator can rotate the mounting base 2 to align the illuminance meter light sensor 62 with the borehole probe (to achieve this, the distance from the center of the detection hole 21 to the connecting shaft 12 should match the distance from the center of the receiving hole 11 to the connecting shaft 12). Then, the borehole probe emits illumination light, which the illuminance meter light sensor 62 collects and quantifies the illumination brightness through the illuminance meter display 63. When testing the clarity of the borehole probe, the operator can rotate the mounting base 2 to align the test card 61 inside the detection slot with the borehole probe (to achieve this, the distance from the center of the detection slot to the connecting shaft 12 should match the distance from the center of the receiving hole 11 to the connecting shaft 12). At this point, the borehole probe will acquire an image of test card 61. For example... Figure 3 As shown, the test card 61 described in this embodiment is a common professional tool in the prior art used to evaluate the performance of various imaging devices, also known as a resolution test card. By using the image captured by the borescope equipment on the test card 61, and in conjunction with commonly used analysis software, the sharpness of the borescope equipment can be quantitatively assessed.

[0036] Optionally, to improve the assembly reliability between the borehole probe and the connector 4, the assembly hole may include a receiving section 431 and a connecting section 432. The inner diameter of the receiving section 431 is equal to the outer diameter of the borehole probe, and the inner diameter of the connecting section 432 is equal to the inner diameter of the probe hole of the borehole probe. When the borehole probe enters the assembly hole, the receiving section 431 limits the outer wall of the borehole probe, and the stepped surface formed between the receiving section 431 and the connecting section 432 limits the end face of the borehole probe, thereby preventing the borehole probe from separating from the connector 4.

[0037] As an optional implementation of this embodiment, in order to improve the smoothness of rotation of the mounting base 2, a rotating bearing 121 may be provided on the connecting shaft 12, and a connecting hole for accommodating the rotating bearing 121 may be provided on the bottom surface of the mounting base 2, thereby facilitating the operator to drive the mounting base 2 to rotate and reducing the wear of the connecting shaft 12.

[0038] In addition, to improve the ease of use of this device, a placement slot 22 can be provided on the top surface of the mounting base 2 to facilitate the display of the illuminance meter 63, thereby freeing the operator's hands during the inspection process of the borehole probe equipment. At the same time, a disassembly and assembly cutout 23 connected to the detection slot can also be provided on the side wall of the mounting base 2 to facilitate the replacement of the test card 61 according to actual needs.

[0039] It should be noted that the illuminance sensor 62 and illuminance display 63 mentioned in this embodiment are common components of existing illuminance products. Their working principles and specific structures are well known to the public and are not part of the inventive point of this application, so they will not be described in detail here.

[0040] In order to adjust the position of the connector 4 inside the adjusting sleeve 3, this embodiment may provide a first positioning block 41 on the outer side wall of the connector 4, and a positioning cutout for accommodating the first positioning block 41 on the side wall of the adjusting sleeve 3.

[0041] like Figure 4 , 5 As shown in Figures 6 and 7, the positioning cut includes a first guide segment 31 and multiple first positioning segments 32. The length direction of the first guide segment 31 is parallel to the length direction of the receiving hole 11. The multiple first positioning segments 32 are arranged along the length direction of the first guide segment 31. The length direction of each first positioning segment 32 is perpendicular to the length direction of the first guide segment 31, and each first positioning segment 32 is connected to the first guide segment 31.

[0042] In use, the operator can drive the first positioning block 41 to move along the first guide section 31, and after moving to the area of ​​a certain first positioning section 32, rotate the connector 4 so that the first positioning block 41 enters the first positioning section 32, thereby quickly completing the position adjustment of the connector 4. During production, production personnel can set the positions of multiple first positioning sections 32 according to the focal length requirements of common borehole drilling equipment, so that multiple first positioning sections 32 can correspond to various focal length requirements, thereby improving the ease of use of the focal length limiting component.

[0043] Optionally, to allow the first positioning block 41 to disengage from the first positioning segment 32 after position adjustment, the first positioning block 41 may be provided with a positioning protrusion 411, and each inner wall of the first positioning segment 32 should be provided with a positioning groove 321 for accommodating the positioning protrusion 411. When the first positioning block 41 enters a certain first positioning segment 32, the positioning protrusion 411 will enter the positioning groove 321 of the current first positioning segment 32, thereby preventing the first positioning block 41 from leaving the current first positioning segment 32 through the cooperation of the positioning protrusion 411 and the positioning groove 321.

[0044] To improve the positional limitation effect of the connector 4 inside the adjusting sleeve 3, this embodiment may also provide a second positioning block 42 on the outer wall of the connector 4, and the second positioning block 42 and the first positioning block 41 should be located on both sides of the axis of the assembly hole. Correspondingly, the inner wall of the adjusting sleeve 3 is provided with a positioning groove for accommodating the second positioning block 42, the positioning groove including a second guide section 33 and a plurality of second positioning sections 34. The length direction of the second guide section 33 is parallel to the length direction of the receiving hole 11, the plurality of second positioning sections 34 are arranged along the length direction of the second guide section 33, and the plurality of second positioning sections 34 are arranged in a one-to-one correspondence with the plurality of first positioning sections 32. The length direction of each second positioning section 34 is perpendicular to the length direction of the second guide section 33, and each second positioning section 34 is connected to the second guide section 33.

[0045] When the first positioning block 41 moves in the positioning cut due to the movement of the connector 4, the second positioning block 42 moves synchronously inside the positioning groove. Since the second positioning block 42 and the first positioning block 41 should be located on both sides of the axis of the assembly hole, the presence of the second positioning block 42 and the positioning groove enables the connector 4 to obtain a more stable and reliable movement effect, avoiding abnormal tilting or movement stagnation of the connector 4.

[0046] In practical applications, different borehole exploration equipment typically has different focal length requirements. To ensure that the focal length limiting component can adapt to more focal length requirements and improve the adjustment accuracy of the focal length limiting component, and to avoid the quantitative detection results of illumination brightness and clarity being affected by the focusing effect, this embodiment can also provide an external thread on the outer wall of the adjusting sleeve 3 and an internal thread that mates with the external thread on the inner wall of the receiving hole 11, so that the adjusting sleeve 3 and the receiving hole 11 can be assembled by a threaded connection. When adapting the focal length requirements of the borehole exploration equipment through the focal length limiting component, the position adjustment of the connector 4 can be regarded as a quick coarse adjustment of the focal length, and the position adjustment of the adjusting sleeve 3 based on the threaded connection can be regarded as a fine adjustment of the focal length. This not only improves the focal length adjustment accuracy of this device, but also further adapts to the focal length requirements of various different borehole exploration equipment.

[0047] In addition, to improve the ease of operation of the adjusting sleeve 3, an operating ring 35 may be provided at the bottom end of the adjusting sleeve 3. The operating ring 35 is located outside the receiving hole 11, and anti-slip stripes are provided on the outer side wall of the operating ring 35. During assembly, the operating ring 35 is located outside the receiving hole 11, so that the operator can rotate the adjusting sleeve 3 through the operating ring 35.

[0048] As another optional implementation of this embodiment, the image acquisition device for quantifying the clarity of the borehole probing equipment may further include a support base. Specifically, the support base includes a connecting rod 51 and a support plate 52, wherein the bottom end of the connecting rod 51 is connected to the top surface of the support plate 52, and the top end of the connecting rod 51 is connected to the bottom surface of the bearing base 1, so that the operator can place the support plate 52 on a table or tabletop. In addition, the support plate 52 should also be provided with an avoidance cut 521 that is aligned with the receiving hole 11, so as to avoid the presence of the support plate 52 obstructing the assembly between the borehole probing equipment and this device.

[0049] The effects of the above solution are explained below:

[0050] This embodiment provides an image acquisition device for quantifying the sharpness of borehole exploration equipment. It allows for alignment of the detection hole or detection slot with the receiving hole through rotation of the mounting base, facilitating the quantitative evaluation of the illumination brightness and sharpness of the borehole exploration equipment. Furthermore, the device can be adjusted in position within the adjusting sleeve using a connecting piece to accommodate the focal length requirements of different borehole exploration equipment.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
