Description

Technical Field

[0001] The invention relates to the technical field of geological rock image acquisition, and in particular to a full-view rock slice image high-resolution acquisition instrument. Background Art

[0002] Rock texture, hue, etc. can accurately reflect the geological conditions. In order to obtain the conditions of underground rock formations, it is usually necessary to collect images of rock samples and analyze the structure of the rock based on the images. The collection of sample images requires the use of a collector containing a microscope camera. Samples usually include directly extracted rock chips and ground rock slices. The thickness of rock slices is relatively thin, which can more accurately reflect the structure of the rock, thereby greatly improving the accuracy of subsequent image analysis.

[0003] At present, the collection of rock thin section images is usually carried out by placing them on a placement table, and then using a microscope camera in conjunction with a light board to capture the thin section. However, there are the following shortcomings when using a collection instrument with this type of structure to collect images: the rock thin sections are relatively thin, and some are even light-transmitting. When they are placed directly on the placement table, it is impossible to fully collect the image of the rock thin section, that is, a single image collection can only obtain a picture of the front side of the rock thin section. In addition, due to the obstruction of the placement table, the rock thin section itself has color aberration, making it difficult to accurately show its own color, which in turn affects the accuracy of image collection.

[0004] To this end, the present invention proposes a full-view rock thin section image high-resolution acquisition instrument. Summary of the invention

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1

[0035] See also Figure 1-5 A full-field rock thin section image high-resolution acquisition instrument includes an acquisition camera 1, a light board 2 and an acquisition platform 3. The acquisition camera 1 adopts a camera with a high-resolution microscope camera used in this field, which can acquire microscopic images in high definition. The acquisition platform 3 is a supporting component of the acquisition instrument.

[0036] In the present technical solution, a portal frame 4 is fixedly connected to the top of the collection platform 3, and two coaxial telescopic drive rods 5 are arranged in the portal frame 4. The telescopic drive rod 5 is an electric telescopic rod structure. The non-action parts of the two telescopic drive rods 5 respectively penetrate and are rotatably connected to the opposite sides in the portal frame 4. The action ends of the two telescopic drive rods 5 are connected to an adaptive clamp 6. The function of the adaptive clamp 6 is to clamp the rock slice. The clamping part can be the outer edge of the rock slice or the side wall of the rock slice. The specific clamping part depends on the strength of the rock slice.

[0037] Specifically, the adaptive clamp 6 includes an elastic telescopic rod 61 and a C-type card 62. The elastic telescopic rod 61 adopts a rod-shaped structure with two sections of telescopic and built-in support springs. The function of the C-type card 62 is to clamp the rock flakes. The C-type card 62 is made of elastic material, such as spring steel. When in use, a layer of silicone pad can be coated on the outside of the C-type card 62. One end of the elastic telescopic rod 61 is fixedly connected to the action end of the telescopic drive rod 5, and the other end is connected to the middle of the C-type card 62 in a damping rotational manner. The C-type card 62 and the elastic telescopic rod 61 are in the same plane and its opening is set away from the elastic telescopic rod 61. In specific implementation, a connecting shaft can be welded at the action end of the elastic telescopic rod 61, a connecting groove is opened in the middle of the outer peripheral wall of the C-type card 62, and then connecting holes are opened on both sides of the connecting groove to be rotatably connected to the connecting shaft, and a rubber sleeve is nested in the connecting hole. It should be noted that the thickness of the C-type card 62 is greater than the outer diameter of the action rod on the telescopic drive rod 5. When in use, the two free ends of the C-shaped clip 62 abut against the outer edge of the rock slice, or the inner arc wall of the C-shaped clip 62 abuts against the outer edge of the rock slice.

[0038] The top of the collection platform 3 is provided with a horizontal placement plate 7 which is located in the door frame 4 and can move up and down. In specific implementation, an electric push rod 101 can be fixedly connected to the bottom of the collection platform 3. The output shaft of the electric push rod 101 passes through the collection platform 3 and is fixedly connected to the bottom of the horizontal placement plate 7. The electric push rod 101 provides driving force for the up and down movement of the horizontal placement plate 7. The function of the horizontal placement plate 7 is to place rock slices. The function of the up and down movement of the horizontal placement plate 7 is to facilitate the docking of the rock slice with the adaptive clamp 6 after lifting it. After the rock slice is docked with the adaptive clamp 6, the horizontal placement plate 7 is controlled to descend. At this time, the rock slice is in a suspended state. When the two telescopic drive rods 5 rotate in the same direction, they can drive the suspended rock slice to flip.

[0039] Furthermore, a circular sink 71 is provided in the middle of the top of the horizontal plate 7. At this time, the outer dimensions of the horizontal plate 7 are larger than the rock slice, and the inner diameter of the circular sink 71 is also larger than the maximum length of the rock slice. A placement platform 711 is fixedly provided at the bottom of the circular sink 71. The placement platform 711 is used to support the rock slice. The outer diameter of the placement platform 711 is smaller than the maximum length of the rock slice. The purpose of this arrangement is to prevent the rock slice from accidentally falling during lifting. A clearance channel 72 is provided at the top of the horizontal plate 7, which is connected to the circular sink 71 and has a clearance fit with the elastic telescopic rod 61. When the elastic telescopic rod 61 is located in the clearance channel 72, the C-type card 62 is located in the circular sink 71. When the C-type card 62 is located in the circular sink 71 and abuts against the inner peripheral wall of the circular sink 71, the C-type card 62 can be reset.

[0040] The acquisition camera 1 is arranged on the top of the gantry 4 and the acquisition lens 11 thereon faces the horizontally placed plate 7, that is, the acquisition lens 11 with microscopic imaging is opposite to the above-mentioned suspended rock slice. When the suspended rock slice rotates, the acquisition lens 11 can capture the full-field image of the rock slice.

[0041] Furthermore, the light board 2 is ring-shaped and fixedly arranged at the top of the portal frame 4. The light board 2 is provided with an illumination lamp and a fluorescent lamp. The light board 2 is sleeved outside the collection lens 11 with a gap. The light board 2 provides a light source downward. A reflective cylinder 8 is suspended in the portal frame 4. In specific implementation, it is preferred that the outer peripheral wall of the reflective cylinder 8 is fixedly connected with a cantilever 81 fixedly connected to the opposite side of the portal frame 4. The adaptive fixture 6 is accommodated in the reflective cylinder 8. The function of the reflective cylinder 8 is that its inner wall reflects the light emitted by the above light source to the suspended rock slice, so that the rock slice itself is more evenly illuminated, thereby improving the clarity of image acquisition.

[0042] The collection platform 3 is provided with an annular driver 9 for driving two coaxial telescopic drive rods 5 to rotate in the same direction. It should be noted that the annular driver 9 can not only simultaneously drive the two telescopic drive rods 5 to rotate in the same direction at the same angular velocity, but also release the control on the rotation drive of the telescopic drive rods 5. When released, the rotation of the telescopic drive rods 5 is unconstrained.

[0043] Specifically, the annular drive 9 includes a transmission ring 91, a guide support frame 92, a drive assembly 93, a transmission sleeve 94 and a control motor 95. There are two guide support frames 92 and they are rotatably arranged on both sides of the portal frame 4. The transmission ring 91 is located between the two guide support frames 92 and is rotatably arranged. The two guide support frames 92 play the role of supporting and rotating the transmission ring 91. The non-action part of the two telescopic drive rods 5 is fixedly sleeved with a transmission sleeve 94. The transmission ring 91 and the transmission sleeves 94 on the two telescopic drive rods 5 are meshed at the same time. In the specific implementation, it is preferred that the upper and lower sides of the transmission ring 91 are fixedly connected with a bevel gear ring 911, and the outer fixed sleeve of the transmission sleeve 94 is provided with a bevel gear 941 meshing with the bevel gear ring 911. Among them, the plane where the transmission ring 91 is located is not parallel to the horizontal plane where the two telescopic drive rods 5 are located. The driving assembly 93 is arranged on one of the guide support frames 92 and is used to control the rotation of the transmission ring 91. The control motor 95 is fixedly connected to the collection platform 3 and is used to control the rotation of the guide support frame 92. The rotation axis of the guide support frame 92 is horizontal and perpendicular to the axis of the telescopic driving rod 5. Therefore, when the guide support frame 92 rotates, the transmission ring 91 will be separated from the transmission sleeves 94 on the two telescopic driving rods 5 at the same time. At this time, the two telescopic driving rods 5 can be manually controlled to rotate in the same direction or in different directions.

[0044] Furthermore, the top of the collection platform 3 is welded with vertical plates 31 located on both sides of the portal frame 4, and the guide support frame 92 includes a support beam 921 and a support groove wheel 922. One side of the support beam 921 is fixedly connected with support groove wheels 922 located at both ends. The support groove wheels 922 and the ring body of the transmission ring 91 are against each other. The cross section of the ring body of the transmission ring 91 is circular, that is, the outer periphery of the transmission ring 91 is supported and limited by at least four support groove wheels 922. When the transmission ring 91 rotates, the support groove wheels 922 can roll relative to it. When in use, a layer of resistance-enhancing rubber sleeve can be bonded to the inner ring groove of the support groove wheel 922. The middle part of the other side of the support beam 921 is fixedly connected with a support shaft 9211 that is rotatably connected to the vertical plate 31, wherein the control motor 1 95 can be fixedly installed on one side of one of the vertical plates 31, and then the output shaft of the control motor 1 95 is fixedly connected to one end of the support shaft 9211.

[0045] In this embodiment, the driving assembly 93 includes a control motor 931 and a driving groove wheel 932. The control motor 931 is fixedly arranged on one side of the support beam 921 and its output shaft is fixedly connected to the driving groove wheel 932. The driving groove wheel 932 and the ring body of the transmission ring 91 are against each other. When the control motor 931 is started, it will drive the driving groove wheel 932 to rotate. Similarly, a layer of resistance-increasing rubber sleeve is bonded to the inner ring groove of the driving groove wheel 932, so that the friction force can be used to drive the transmission ring 91 to rotate.

[0046] Working principle: When in use, start the electric push rod 101 to make the horizontal placement plate 7 at the lowest position, then extend the rock slice from the bottom of the reflective tube 8 and place it flat on the placement table 711 in the circular sink 71, and then control the electric push rod 101 to push at a low speed, the horizontal placement plate 7 rises and drives the rock slice to rise between the two C-type clamps 62, preparing for the docking of the rock slice and the C-type clamp 62.

[0047] When the rock slice is hard, the two telescopic drive rods 5 can be directly controlled to push at the same time, and the two C-type clamps 62 are in the same plane and move in opposite directions at the same time. The free end of the C-type clamp 62 will contact the outer wall of the rock slice, and the elastic telescopic rod 61 will be compressed. At this time, the rock slice is clamped, and the horizontal placement plate 7 is controlled to descend. The clamped rock slice is in a suspended state. At this time, the acquisition camera 1 and the light board 2 are turned on, and the control motor 2 931 is started. The driving groove wheel 932 drives the transmission ring 91 to rotate, and the teeth on the bevel gear ring 911 drive the bevel gear 941 to rotate. The two telescopic drive rods 5 rotate in the same direction and at the same angle, which can drive the suspended rock slice to flip, and the acquisition lens 11 can clearly obtain the full-field image of the rock slice.

[0048] When the rock slice is soft and not suitable for direct clamping, the control motor 95 is started to control the support shaft 9211 to rotate, so that the active transmission ring 91 is further tilted, and the bevel gear ring 911 is disengaged from the bevel gear 941. At this time, the two telescopic drive rods 5 can be manually controlled to rotate in different directions so that the two C-type clips 62 are not in the same plane. Then the telescopic drive rod 5 is controlled to push, and the C-type clip 62 will buckle into the rock slice. The inner arc wall of the C-type clip 62 and the outer edge of the rock slice are abutted. Then the two telescopic drive rods 5 are controlled to rotate alternately, so that the two C-type clips 62 are in a state of twisting and clamping the rock slice. Then the transmission ring 91 is reset to continue high-resolution imaging of the soft rock slice.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
