Description

Technical Field

[0001] This utility model relates to borehole detection equipment, specifically to a panoramic borehole camera. Background Technology

[0002] In blasting operations, the quality and stability of the blast holes are crucial for ensuring blasting effectiveness and construction safety. Hole inspection is an important task aimed at detecting potential hazards or problems inside the blast holes, such as cracks and water layers. Currently, the main equipment for hole inspection is the panoramic borehole camera.

[0003] A panoramic drilling camera typically includes a tripod, a probe, and a winding mechanism for rewinding the probe. In use, the probe is placed into the borehole through the winding mechanism, and the probe transmits the image inside the borehole, allowing for borehole inspection.

[0004] However, for inclined boreholes, after the probe is placed, it cannot stay on the center line of the borehole, but instead sticks to the lower borehole wall, resulting in poor image quality and the inability to stitch the images together later. Utility Model Content

[0005] The technical problem to be solved by this utility model is that, in view of the shortcomings of existing panoramic drilling cameras in detecting tilted boreholes, this utility model provides a panoramic drilling camera that can center the probe.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A panoramic drilling camera includes a probe, a support frame, and a first winding assembly mounted on the support frame. One end of a connecting cable is wound around the first winding assembly, and the other end of the cable is fixedly connected to the probe. Its structural features are as follows:

[0008] The adjustment mechanism includes a drive module and an adjustment module. The adjustment module includes a first positioning sleeve and at least one set of adjustment components. The first positioning sleeve is detachably fitted onto the probe via the connecting component. The adjustment component includes at least two opposing adjustment rods. One end of each adjustment rod is movably connected to the first positioning sleeve, and the other end is used to abut against the inner wall of the borehole. The drive module drives each adjustment rod of the adjustment component to move away from each other, so that the end of each adjustment rod away from the first positioning sleeve abuts against the inner wall of the borehole.

[0009] In use, the probe is lowered to the bottom of the borehole via the first winding assembly. Then, the drive module drives the adjustment rods to move away from each other, ensuring that the ends of the adjustment rods furthest from the first positioning sleeve contact the inner wall of the borehole. At this point, due to the relative arrangement of the adjustment rods and the reaction force of the borehole wall, the probe is positioned on the centerline of the borehole. The first winding assembly then pulls the probe out. During this process, because the adjustment rods remain in contact with the borehole wall, the probe can move along the centerline of the borehole until it is removed. Even if the borehole is tilted, the probe will not deviate towards the lower borehole wall, thus facilitating panoramic imaging inspection of tilted boreholes. Furthermore, by changing the length of the adjustment rods, it can be adapted to boreholes of different diameters.

[0010] Preferably, the drive module includes an air pump, a first cylinder, a sliding sleeve, and a connecting rod. The air pump is mounted on the support frame. The rodless chamber of the first cylinder is connected to the air outlet of the air pump. The piston rod of the first cylinder is connected to the sliding sleeve, which is slidably mounted on the probe. One end of the connecting rod is connected to the adjusting rod, and the other end is connected to the sliding sleeve. The adjusting rod is hinged to the first positioning sleeve. Thus, air can be injected into the first cylinder by the air pump. Under air pressure, the piston rod of the first cylinder drives the sliding sleeve to slide, which in turn drives the adjusting rod to rotate away from the probe via the connecting rod until the adjusting rod contacts the inner wall of the borehole. This drive module utilizes airflow to transmit power and can adapt well to the environment of the borehole.

[0011] Preferably, the adjustment module further includes a second positioning sleeve, the first positioning sleeve is installed on the lower part of the probe, the second positioning sleeve is installed on the upper part of the probe, the first cylinder is installed on the second positioning sleeve, and the sliding sleeve is installed between the first positioning sleeve and the second positioning sleeve.

[0012] Preferably, the guiding assembly includes a second winding assembly, a guide rope, and a guide ring. The second winding assembly includes a second winding roller, on which one end of the guide rope is wound and connected. The other end of the guide rope is connected to the end of the adjusting rod away from the first positioning sleeve. The guide ring is fixedly connected to the probe via a connecting rod, and the guide ring is located directly above the preset borehole contact position of the adjusting rod. The guide rope passes through the guide ring and connects to the second winding roller. After the probe is adjusted to the borehole centerline, the second winding assembly is used to taut the guide rope, and then the first winding assembly is used to pull the probe out of the borehole. With the cooperation of the guide ring and the taut guide rope, the probe can remain on the borehole centerline throughout its upward movement.

[0013] Preferably, the shaft of the second take-up roller is connected to the output shaft of the second motor.

[0014] Preferably, the second take-up roller is provided with a handle for rotating the second take-up roller, and the second take-up roller is provided with a ratchet and pawl structure for limiting the rotation of the second take-up roller.

[0015] Preferably, the support frame includes a support platform and four support legs rotatably mounted on the support platform. Each support leg is equipped with a second winding assembly. There are two sets of adjustment assemblies. Each set of adjustment assemblies has two adjustment rods. Each adjustment rod is equidistantly connected to the peripheral wall of the first positioning sleeve. The end of each adjustment rod away from the first positioning sleeve is connected to a guide rope. The other end of the guide rope is connected to the second winding assembly in a corresponding manner.

[0016] Preferably, the connecting assembly includes an electromagnet, a battery for powering the electromagnet, and an annular groove formed on the inner wall of the first and / or second positioning sleeves. The battery is electrically connected to the electromagnet, which is secured within the annular groove and attracted to the outer wall of the probe. Thus, the connection and separation of the first and second positioning sleeves and the probe can be achieved by switching the electromagnet on and off, which is simple and convenient.

[0017] Preferably, the battery is mounted on the first positioning sleeve, the second positioning sleeve, or the support frame.

[0018] Preferably, the drive module includes an air pump, a first cylinder, a sliding sleeve, and a second cylinder. The air pump is mounted on the support frame. The rodless chamber of the first cylinder is connected to the air outlet of the air pump. The piston rod of the first cylinder is connected to the sliding sleeve. The sliding sleeve is slidably mounted on the probe. The second cylinder is mounted below the sliding sleeve. The piston rod of the second cylinder is connected to the sliding sleeve. A spring is installed in the rodless chamber of the second cylinder. A slot is radially provided on the first positioning sleeve for the adjustment rod to slide into. The adjustment rod is slidably inserted into the slot. The slot is connected to the rodless chamber of the second cylinder.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1) After the probe is lowered to the bottom of the borehole, the present invention uses an adjustment mechanism to adjust the probe to the center line of the borehole. Then, a taut guide rope and a guide ring are used to guide the probe to move upward, so that the probe is always on the center line of the borehole when it is pulled out of the borehole by the first winding assembly, which facilitates the detection of inclined boreholes.

[0021] 2) This utility model uses an electromagnet to connect and separate the first and second positioning sleeves and the probe, which is simple and convenient to use. Attached Figure Description

[0033] Reference Figure 1 - Figure 3 The panoramic drilling camera of this utility model, in embodiment one, includes a probe 1, a support frame, and a first winding assembly mounted on the support frame. The support frame is a four-legged structure, including a support platform 2 and four support legs 3 rotatably mounted on the support platform 2. The first winding assembly includes a first winding roller 4 and a first motor 5. One end of a cable 6 is wound and fixed on the first winding roller 4, and the other end of the cable 6 passes around a fixed pulley on the support platform 2 and is fixedly connected to the upper end of the probe 1. The output shaft of the first motor 5 is connected to the rotating shaft of the first winding roller 4, and the first motor 5 drives the first winding roller 4 to rotate to realize the winding and unwinding of the cable 6.

[0034] The panoramic drilling camera of this utility model, in embodiment one, also includes an adjustment mechanism and a connecting assembly. The adjustment mechanism includes an adjustment module and a drive module. The adjustment module includes a first positioning sleeve 7, a second positioning sleeve 26, and at least one set of adjustment components. The first positioning sleeve 7 is detachably mounted on the lower part of the probe 1 via the connecting assembly, and the second positioning sleeve 26 is detachably mounted on the upper part of the probe 1 via the connecting assembly. The adjustment components are provided in two sets, each set including two adjustment rods 8 arranged opposite each other. The four adjustment rods 8 are equidistantly hinged to the peripheral wall of the first positioning sleeve 7, and one end of the adjustment rod 8 is hinged to the first positioning sleeve 7, while the other end is used to abut against the inner wall of the borehole.

[0035] Under the action of the drive module, each adjusting rod 8 can rotate synchronously away from each other until the end of the adjusting rod 8 away from the first positioning sleeve touches the inner wall of the blast hole.

[0036] The drive module includes an air pump 10, a first cylinder 11, a sliding sleeve 9, and a connecting rod 14. The air pump 10 is fixedly mounted on the support platform 2. The air outlet of the air pump 10 is connected to one end of a flexible hose 13, and the other end of the flexible hose 13 is connected to the rodless chamber of the first cylinder 11. The sliding sleeve 9 is located between the first positioning sleeve 7 and the second positioning sleeve 26, and the sliding sleeve 9 can slide along the length of the probe 1. The first cylinder 11 is fixedly connected to the second positioning sleeve 26. The piston rod 12 of the first cylinder 11 is connected to the sliding sleeve 9, and the sliding sleeve 9 is slidably mounted on the probe 1. One end of the connecting rod 14 is hinged to the middle of the adjusting rod 8, and the other end is hinged to the sliding sleeve 9. When the air pump 10 injects air into the first cylinder 11, under the action of air pressure, the piston rod 12 of the first cylinder 11 drives the sliding sleeve 9 to slide downward. Through the connecting rod 14, the adjusting rod 8 can be driven to rotate away from the probe 1 until the end of the adjusting rod 8 away from the first positioning sleeve touches the inner wall of the borehole. The panoramic drilling camera embodiment of this utility model also includes a guide assembly, which includes a second winding assembly, guide ropes 15, and guide rings 16. In this embodiment, the second winding assembly is installed on each of the four support feet 22. The second winding assembly includes a second motor 17 and a second winding roller 18. The second motor 17 is fixedly connected to the support feet 22, and the output shaft of the second motor 17 is fixedly connected to the rotating shaft of the second winding roller 18. Four guide ropes 15 are also provided. The lower end of the guide rope 15 is fixedly connected to the end of the adjusting rod 8 away from the first positioning sleeve 7, and the other end is wound and fixedly connected to the second winding roller 18. Four connecting rods 25 are fixedly connected to the upper end of the probe 1. Guide rings 16 are fixedly connected to the ends of the four connecting rods 25 away from the probe. The four guide rings 16 are respectively sleeved on the four guide ropes 15, and each guide ring 16 is located directly above the preset blast hole contact position of the adjusting rod 8. After the probe 1 is aligned with the center line of the borehole, the guide rope 15 is kept taut by the second take-up roller 18. Then, the probe 1 is pulled out of the borehole by the first take-up assembly. With the cooperation of the guide ring 16 and the taut guide rope 15, the probe 1 can always be kept on the center line of the borehole during the upward movement.

[0037] In some embodiments, the second take-up assembly may also use a handle to drive the second take-up roller 18 to rotate, and a ratchet and pawl structure may be provided accordingly to restrict the rotation of the second take-up roller 18 so that the guide rope 15 can be kept taut.

[0038] In this embodiment, the connecting component includes an electromagnet 19. The inner walls of the first positioning sleeve 7 and the second positioning sleeve 26 are respectively provided with annular grooves 20. The electromagnet 19 is in the shape of a ring and can be adapted to be fixed in the annular groove 20. The electromagnet 19 is used to adsorb the outer wall of the probe 1.

[0039] In this embodiment, a storage battery is installed on the first positioning sleeve 7 and the second positioning sleeve 26 to supply power to the electromagnet 19. The electromagnet 19 can be controlled to open and close by remote control or other remote means. In other embodiments, the storage battery can also be placed on the support platform 2 and the electromagnet 19 can be powered by wires.

[0040] When using this panoramic drilling camera, the probe 1 is lowered to the bottom of the borehole. Then, the air pump 10 injects air into the first cylinder 11. The air pressure in the first cylinder 11 drives the piston rod 12 to move, which in turn drives the sliding sleeve 9 to move along the length of the probe 1. At the same time, as the sliding sleeve 9 slides, it drives the connecting rod 14 and the adjusting rod 8 to rotate accordingly. The two adjusting rods 8 rotate synchronously away from each other until the end of the adjusting rod 8 away from the first positioning sleeve touches the inner wall of the borehole. Thus, under the reaction force provided by the inner wall of the borehole, the probe 1 is adjusted to the center line of the borehole. Then, by controlling the rotation of the second take-up roller 18, the guide rope 15 is kept taut. Finally, the first take-up assembly pulls the probe 1 out of the borehole. During this process, the guide ring 16, in conjunction with the guide rope 15, ensures that the probe 1 is always located on the center line of the borehole, which facilitates the detection of inclined boreholes.

[0041] Reference Figure 4 The adjusting rod 8 can also be slidably inserted into the first positioning sleeve 7 along the length direction perpendicular to the probe 1. The first positioning sleeve 7 has multiple slots 21 for the adjusting rod 8 to slide into. The first positioning sleeve 7 is fixedly connected to the second cylinder 24. Correspondingly, there are four second cylinders 24. One end of the piston rod 23 of the second cylinder 24 is located outside the second cylinder 24 and on the moving path of the sliding sleeve 9. The four slots 21 are respectively connected to the rodless chambers of the four second cylinders 24. A spring 22 is fixedly connected inside the rodless chamber of the second cylinder 24. In use, the probe 1 is lowered to the bottom of the borehole. Then, the air pump 10 is used to inject air into the first cylinder 11, which drives the piston rod 12 of the first cylinder 11 to move, thereby driving the sliding sleeve 9 to move. The sliding sleeve 9 slides, pushing the piston rod 23 of the second cylinder 24 to compress the spring 22 and move, thereby injecting air into the slot 21. Under the action of air pressure, the adjusting rod 8 moves towards the inner wall of the borehole and abuts against the inner wall of the borehole.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of this utility model. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the content of the technical solution of this utility model should fall within the protection scope of the technical solution of this utility model.
