Description

Technical Field

[0001] This invention relates to the field of shale reservoir fracture detection equipment, specifically to a mineral scanning device for shale reservoir fracture detection. Background Technology

[0002] Shale reservoir fracture detection is a key technology for efficient shale oil and gas exploration and development. Its core lies in identifying, describing, and evaluating the spatial distribution, geometry, connectivity, and seepage characteristics of natural and artificial fractures in the reservoir. This technology typically employs a multidisciplinary, multi-scale fusion approach: at the microscale, scanning electron microscopy, micro-CT, and core analysis are used to observe the morphology and filling of fractures. Mineral scanning equipment is a crucial tool for rapid, multi-scale identification and analysis of mineral composition. Its core lies in identifying and quantifying minerals by detecting their response characteristics to different energies (such as electromagnetic waves, X-rays, and gamma rays).

[0003] Patent document (CN219227668U) discloses a scanning device that places the display screen and scanning port on opposite sides, increasing the aspect ratio of the display screen. When using this device, it can be placed flat on the medium to be scanned, eliminating the need to lift it by hand. However, this scanning device is unsuitable for shale reservoir fracture detection because the lens of the mineral scanning device, due to prolonged outdoor operation, easily accumulates dust and impurities, compromising the accuracy of subsequent scans and affecting the scan quality.

[0004] Currently, scanning equipment used for shale reservoir fracture detection generally suffers from dust and impurities adhering to its lens surface, making timely cleaning difficult and hindering long-term operation. Manual cleaning requires repeated trips to the site and even relocation of the equipment, resulting in a heavy workload. Therefore, it is necessary to redesign mineral scanning equipment to effectively prevent dust accumulation on its lens surface. Summary of the Invention

[0005] To address at least one of the above technical problems, this invention provides a mineral scanning device for detecting fractures in shale reservoirs.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: This invention provides a mineral scanning device for detecting fractures in shale reservoirs, comprising a support frame on which a scanning head is mounted, and a lens on the front side of the scanning head; a cleaning slider and a cleaning drive are slidably connected to the top of the scanning head, the output end of the cleaning drive is connected to the cleaning slider and can drive the cleaning slider to slide left and right; a cleaning component is mounted on the cleaning slider, the cleaning part of the cleaning component extends to the front side of the scanning head, and can scan the surface of the lens under the action of the left and right sliding of the cleaning slider.

[0007] The beneficial effects of this invention are: By employing this invention, a cleaning slider is driven by a cleaning drive unit to slide left and right on the top of the scanning head. The cleaning slider and cleaning components move left and right, allowing the cleaning part to sweep across the surface of the lens. This achieves automatic and timely cleaning of dust and impurities adsorbed on the lens surface, ensuring stable scanning clarity during long-term use of the equipment. The start and stop of the cleaning drive unit can be controlled remotely or by a program, eliminating the need for operators to repeatedly travel to the site, thus reducing workload and lens maintenance costs.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the cleaning drive includes a cleaning motor and a screw. The cleaning motor is fixed to the top of the scanning head, the screw is arranged in the left-right direction and its first end is connected to the output shaft of the cleaning motor, the second end of the screw is rotatably connected to the top of the scanning head, the screw passes through the cleaning slider and is threadedly connected to the cleaning slider; the cleaning slider is slidably connected to the scanning head.

[0010] When the cleaning motor drives the screw to rotate, it can cause the cleaning slider to slide left and right, which has good stability. In addition, the spare space of the screw can be used to drive additional cleaning components to improve the cleaning effect.

[0011] Furthermore, an output wheel is fixed to one end of the screw; a fan mounting base is also fixed to the scanning head, and a cleaning fan is rotatably connected to the fan mounting base, with the cleaning fan being connected to the output wheel via a transmission; the lens is located on the air outlet side of the cleaning fan.

[0012] This design facilitates the coordinated operation of the cleaning components and the cleaning fan. While the cleaning components sweep away dust, the cleaning fan blows away the disturbed dust, creating a dual dust removal effect of sweeping and blowing. At the same time, the cleaning fan can achieve a self-cleaning effect on the cleaning components, preventing secondary contamination. Furthermore, by driving both the cleaning components and the cleaning fan simultaneously through a screw, the rapid rotation of the cleaning fan and the slow sliding of the cleaning slider can coexist, resulting in a compact structure.

[0013] Furthermore, the top of the scanning head is also provided with an elastic component, the front side of which is provided with a plurality of first convex balls, and the rear side of the cleaning slider is fixed with a second convex ball. The first convex balls are distributed in the left-right direction and are at the same height as the second convex balls. When the cleaning slider slides left and right, it can drive the second convex balls to contact the first convex balls.

[0014] By colliding with the first convex ball, the cleaning slider can be subjected to an instantaneous vibration, thereby shaking off the dust on the cleaning component and realizing the automatic cleaning of the cleaning component; at the same time, the elastic component can buffer and absorb the impact force between the second convex ball and the first convex ball, thereby achieving buffering and avoiding structural interference.

[0015] Furthermore, the elastic component includes two elongated plates arranged opposite each other in the front-back direction, the elongated plates extending in the left-right direction, and the two elongated plates are connected by multiple springs; the elongated plate located on the front side slides in contact with the top of the scanning head, and the first convex ball is fixed on its front side, while the elongated plate located on the rear side is fixed to the top of the scanning head.

[0016] This design facilitates the installation of multiple first convex balls at equal heights along the left and right directions, resulting in a compact structure. Simultaneously, the elongated plate at the front slides in contact with the top of the scanning head, ensuring the first convex balls maintain a stable height and are at the same height as the second convex balls, guaranteeing reliable contact between them. Furthermore, multiple springs evenly absorb the impact force between the second and first convex balls, reducing the vibration amplitude of the first convex balls and increasing the vibration frequency of the second convex balls, thereby enhancing the self-cleaning effect of the cleaning assembly.

[0017] Furthermore, a protective cover is provided above the scanning head; the cleaning drive, cleaning slider, and elastic component are all located inside the protective cover.

[0018] It facilitates the protection of the cleaning drive components, cleaning slider, and elastic components, preventing foreign objects such as gravel from falling in and affecting the smoothness of movement. At the same time, it can protect the top of the scanning head from damage caused by external impacts.

[0019] Furthermore, multiple pressure-resistant cotton strips are fixed to the top of the protective cover; arc-shaped side plates are fixed to both ends of the protective cover, and the arc-shaped side plates are fixedly connected to the ends of the scanning head.

[0020] The pressure-resistant cotton strips prevent foreign objects from making hard contact with the top of the protective cover, reducing impact force; the arc-shaped side plates can produce elastic deformation to absorb the impact force of external impacts; thus, it is easy to protect the top of the scanning head from damage by external impacts, and has good reliability.

[0021] Furthermore, the cleaning assembly includes a support plate, the first end of which is fixed to the cleaning slider, and the second end of which is provided with a rotation drive. The rotation axis of the rotation drive is arranged vertically and its lower end is connected to a cleaning brush rod. The cleaning brush rod can sweep across the surface of the lens under the action of the left and right sliding motion of the cleaning slider.

[0022] The rotating drive unit drives the cleaning brush arm to rotate, making it easier for the cleaning brush arm to sweep across the lens surface, thereby achieving a secondary cleaning of stubborn dust on the lens surface and improving the cleaning effect.

[0023] Furthermore, the rotation drive is a gear and is rotatably connected to the second end of the support plate; a horizontal rack is also fixed on the scanning head, and the rotation drive meshes with the horizontal rack.

[0024] When the screw drives the cleaning slider and support plate to move horizontally, the gear meshes with the horizontal rack to make the gear rotate, thereby driving the cleaning brush rod to rotate. This saves on additional drive components, resulting in a compact structure and low cost. At the same time, it ensures the synchronization between the rotation of the cleaning brush rod and its horizontal movement.

[0025] Furthermore, the rear side of the scanning head is also provided with two sliding frames, left and right. The sliding frames are slidably connected to the scanning head and can slide left and right. The sliding frames are provided with vertical sliding grooves. The opposite sides of the left and right sliding frames are fixed with plug anti-loosening claws. An anti-loosening motor is provided between the sliding frame and the scanning head. The anti-loosening motor is fixed to the scanning head and a turntable is fixed on its output shaft. A sliding pin is fixed on one side of the rotation axis of the turntable and extends into the vertical slide groove.

[0026] When the scanning head is connected to an external plug, the anti-loosening motor drives the turntable to rotate. The sliding pin on the turntable can slide along the vertical slide groove, while simultaneously pushing the side wall of the vertical slide groove vertically, thereby causing the sliding frame to slide horizontally to move closer to or away from another sliding frame. When the two sliding frames are close to each other, their plug anti-loosening claws can clamp onto the plug, thereby achieving a locking and anti-loosening effect on the plug and improving the reliability of the equipment. When the two sliding frames are far apart, the plug anti-loosening claws leave the plug, making it easy to plug and unplug the plug and making operation convenient. Attached Figure Description

Detailed Implementation

[0036] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0037] See also: This invention Figure 1-8 .

[0038] This invention provides a mineral scanning device for detecting fractures in shale reservoirs, comprising a support 1, on which a scanning head 2 is mounted, and a lens 3 is provided on the front side of the scanning head 2; a cleaning slider 4 and a cleaning drive are slidably connected to the top of the scanning head 2, the output end of the cleaning drive is connected to the cleaning slider 4 and can drive the cleaning slider 4 to slide left and right; a cleaning component is mounted on the cleaning slider 4, the cleaning part of the cleaning component extends to the front side of the scanning head 2, and can sweep across the surface of the lens 3 under the drive of the left and right sliding of the cleaning slider 4.

[0039] principle: The scanning head 2 can be fixed to the bracket 1 or connected to the top of the bracket 1 via a damping pivot, and its angle can be adjusted around the pivot. The bracket 1 provides stable support for the scanning head 2, which is used to mount the lens 3 and related optical instruments (such as scanners, cameras, etc.), together forming the basic scanning equipment. To solve the problem that dust easily adheres to the surface of the lens 3, affecting scanning clarity, this invention uses a cleaning drive component to drive a cleaning slider 4 to slide left and right on the top of the scanning head 2. The cleaning slider 4 drives the cleaning component to move left and right, so that the cleaning part of the cleaning component sweeps across the surface of the lens 3, achieving timely cleaning of dust and impurities adsorbed on the surface of the lens 3. The cleaning drive component can be a motor, telescopic rod, etc., and can be any existing product with remote wired signal control or remote control, thus eliminating the need for repeated trips to the site and reducing workload.

[0040] In summary, by employing this invention, the cleaning slider 4 is driven by the cleaning drive component to slide left and right on the top of the scanning head 2. The cleaning component of the cleaning slider 4 moves left and right, so that its cleaning part sweeps across the surface of the lens 3, realizing automatic and timely cleaning of dust and impurities adsorbed on the surface of the lens 3, ensuring stable scanning clarity during long-term use of the equipment. The start and stop of the cleaning drive component can be controlled remotely or by program, eliminating the need for operators to repeatedly travel to the site, reducing workload and maintenance costs of the lens 3.

[0041] Furthermore, such as Figure 3-5 As shown: The cleaning drive component includes a cleaning motor 5 and a screw 6. The cleaning motor 5 is fixed to the top of the scanning head 2. The screw 6 is arranged in the left-right direction and its first end is connected to the output shaft of the cleaning motor 5. The second end of the screw 6 is rotatably connected to the top of the scanning head 2. The screw 6 passes through the cleaning slider 4 and is threadedly connected to the cleaning slider 4. The cleaning slider 4 is slidably connected to the scanning head 2.

[0042] Preferably, the first end of the screw 6 is sleeved on the output shaft of the cleaning motor 5 and connected to the output shaft of the cleaning motor 5 via a spline; a bearing seat is fixed on the top of the scanning head 2, and the second end of the screw 6 is rotatably connected to the bearing seat via a bearing.

[0043] When the cleaning motor 5 drives the screw 6 to rotate, it can drive the cleaning slider 4 to slide left and right, which has good stability. In addition, the spare space of the screw 6 can be used to drive additional cleaning components to improve the cleaning effect.

[0044] Furthermore, an output wheel 7 is fixed to one end of the screw 6; a fan mounting base 8 is fixed to the scanning head 2, and a cleaning fan 9 is rotatably connected to the fan mounting base 8. The cleaning fan 9 is connected to the output wheel 7 in a transmission manner; the lens 3 is located on the air outlet side of the cleaning fan 9.

[0045] Preferably, the output wheel 7 is a pulley, and the cleaning fan 9 is coaxially connected to the input pulley, which is connected to the output wheel 7 by belt drive.

[0046] The cleaning components and cleaning fan 9 work together to facilitate the cleaning components to sweep away dust while the cleaning fan 9 blows away the disturbed dust, forming a dual dust removal effect of sweeping and blowing. At the same time, the cleaning fan 9 can achieve a self-cleaning effect on the cleaning components to avoid secondary contamination. In addition, the screw 6 drives the cleaning components and cleaning fan 9 simultaneously, realizing the coexistence of rapid rotation of the cleaning fan 9 and slow sliding of the cleaning slider 4, resulting in a compact structure.

[0047] Furthermore, such as Figure 5-6 As shown: The top of the scanning head 2 is also provided with an elastic component. The front side of the elastic component is provided with a plurality of first convex balls 10. The rear side of the cleaning slider 4 is fixed with a second convex ball 11. The first convex balls 10 are distributed in the left and right direction and are at the same height as the second convex balls 11. When the cleaning slider 4 slides left and right, it can drive the second convex balls 11 to contact the first convex balls 10.

[0048] By colliding and contacting the second convex ball 11 with the first convex ball 10, an instantaneous vibration can be applied to the cleaning slider 4, thereby shaking off the dust on the cleaning component and realizing the automatic cleaning of the cleaning component; at the same time, the elastic component can buffer and absorb the impact force between the second convex ball 11 and the first convex ball 10, thereby achieving buffering and avoiding structural interference.

[0049] Furthermore, the elastic component includes two elongated plates 12 arranged opposite each other in the front-back direction, the elongated plates 12 extending in the left-right direction, and the two elongated plates 12 are connected by a plurality of springs 13; the elongated plate 12 located on the front side slides in contact with the top of the scanning head 2, and the first convex ball 10 is fixed on its front side, and the elongated plate 12 located on the rear side is fixed to the top of the scanning head 2.

[0050] This design facilitates the installation of multiple first convex balls 10 at equal heights along the left and right directions, resulting in a compact structure. Simultaneously, the elongated plate 12 on the front side slides in contact with the top of the scanning head 2, ensuring the height of the multiple first convex balls 10 remains stable and equal to that of the second convex balls 11, guaranteeing reliable contact between them. Furthermore, multiple springs 13 can evenly absorb the impact force between the second convex balls 11 and the first convex balls 10, reducing the vibration amplitude of the first convex balls 10 and increasing the vibration frequency of the second convex balls 11, thereby improving the self-cleaning effect of the cleaning assembly.

[0051] Furthermore, such as Figure 1 , 3 As shown in Figures 5 and 7: A protective cover 14 is provided above the scanning head 2; the cleaning drive, cleaning slider 4 and elastic component are all located inside the protective cover 14.

[0052] It facilitates the protection of the cleaning drive components, cleaning slider 4, and elastic components, preventing foreign objects such as gravel from falling in and affecting the smoothness of movement. At the same time, it can protect the top of the scanning head 2 from damage caused by external impacts.

[0053] Furthermore, multiple pressure-resistant cotton strips 15 are fixed to the top of the protective cover 14; arc-shaped side plates 16 are fixed to both ends of the protective cover 14, and the arc-shaped side plates 16 are fixedly connected to the ends of the scanning head 2.

[0054] The pressure-resistant cotton strip 15 can prevent foreign objects from making hard contact with the top of the protective cover 14, reducing the impact force; the arc-shaped side plate 16 can produce elastic deformation to absorb the impact force of external impact; thus, it is convenient to protect the top of the scanning head 2 from damage by external impact, and has good reliability.

[0055] Furthermore, such as Figure 3 , 5 As shown: The cleaning assembly includes a support plate 17. The first end of the support plate 17 is fixed to the cleaning slider 4. The second end of the support plate 17 is provided with a rotation drive 18. The rotation axis of the rotation drive 18 is arranged vertically and its lower end is connected to a cleaning brush rod 19. The cleaning brush rod 19 can sweep across the surface of the lens 3 under the drive of the cleaning slider 4 sliding left and right.

[0056] Preferably, the outer periphery of the cleaning brush handle 19 is fixed with electrostatically adsorbed bristles. The rotation drive 18 can be an independent motor or other transmission structure, and its function is to drive the cleaning brush handle 19 to rotate.

[0057] The rotating drive component 18 drives the cleaning brush rod 19 to rotate, which makes it easier for the cleaning brush rod 19 to rotate and sweep across the surface of the lens 3, thereby achieving a secondary cleaning of stubborn dust on the surface of the lens 3 and improving the cleaning effect.

[0058] Furthermore, the rotation drive 18 is a gear and is rotatably connected to the second end of the support plate 17; a horizontal rack 20 is also fixed on the scanning head 2, and the rotation drive 18 meshes with the horizontal rack 20.

[0059] When the screw 6 drives the cleaning slider 4 and the support plate 17 to move horizontally, the gear meshes with the horizontal rack 20 to make the gear rotate, thereby driving the cleaning brush rod 19 to rotate. This saves on additional driving components, resulting in a compact structure and low cost. At the same time, it ensures the synchronization between the rotation of the cleaning brush rod 19 and its horizontal movement.

[0060] Furthermore, such as Figure 7-8 As shown: The rear side of the scanning head 2 is also provided with two sliding frames 21 on the left and right. The sliding frames 21 are slidably connected to the scanning head 2 and can slide left and right. The sliding frames 21 are provided with vertical sliding grooves. The opposite side of the left and right sliding frames 21 is fixed with plug anti-loosening claws 22. An anti-loosening motor 23 is provided between the sliding frame 21 and the scanning head 2. The anti-loosening motor 23 is fixed on the scanning head 2 and a turntable 24 is fixed on its output shaft. A sliding pin 25 is fixed on one side of the rotation axis of the turntable 24 and the sliding pin 25 extends into the vertical slide groove.

[0061] Note: The scanning head 2 needs to be connected to an external plug 26 for electrical and signal connection with the outside world. Preferably, the anti-loosening motor 23 is a disc motor.

[0062] When the scanning head 2 is connected to the external plug 26, the anti-loosening motor 23 drives the turntable 24 to rotate. The sliding pin 25 on the turntable 24 can slide along the vertical slide groove, and at the same time pushes the side wall of the vertical slide groove vertically, thereby causing the sliding frame 21 to slide horizontally to approach or move away from another sliding frame 21. When the two sliding frames 21 approach each other, their plug anti-loosening claws 22 can clamp on the plug 26, thereby achieving the locking and anti-loosening effect of the plug 26 and improving the reliability of the equipment. When the two sliding frames 21 move away from each other, the plug anti-loosening claws 22 leave the plug 26, making it easy to plug and unplug the plug 26 and making the operation convenient.
