Description

Technical Field

[0001] This utility model relates to the field of drilling, and more specifically to a drilling bracket. Background Technology

[0002] Drilling is a necessary operation for oil extraction from sunken ships. Before extraction, the operator needs to drill a through hole at a predetermined location on the sunken ship to connect to the oil tank, and then insert an oil extraction pipe to extract the oil from the sunken ship's oil tank.

[0003] In existing technologies, the through-hole remains open for an extended period before the oil pipe is inserted, causing a significant amount of oil to leak from the tank, resulting in substantial waste and severe environmental pollution at the work site.

[0004] On the other hand, in the existing technology, when using a hole-drilling device to drill a hole, a first fixing device is needed to assist in fixing the hole-drilling device. After the hole is drilled, a second fixing device is needed to fix the oil pumping pipe. This is not only cumbersome to operate, but also greatly increases the operating cost. Utility Model Content

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] refer to Figures 1 to 5 This application provides a punching bracket 100, which includes a base plate 10 and a ball valve mechanism 20. The base plate 10 is adapted to be fixed to the outside of the oil tank of a sunken ship, and the base plate 10 has a first opening 11 at a predetermined position. The ball valve mechanism 20 includes a valve housing 21 and a spherical valve core 22. The valve housing 21 has a first flow channel 210, the bottom of the valve housing 21 is mounted on the base plate 10, and the bottom opening of the first flow channel 210 communicates with the first opening 11; the valve housing 21 also has a rotating cavity 211 communicating with the first flow channel 210, and the spherical valve core 22 is rotatably mounted in the rotating cavity 211, and the spherical valve core 22 has a second flow channel 220.

[0033] refer to Figure 4The ball valve mechanism 20 has an open state and a closed state. In the open state, the center line of the second flow channel 220 coincides with the center line of the first flow channel 210, and the second flow channel 220 connects the first flow channel 210 located on the upper and lower sides of the ball valve core 22. When the ball valve mechanism 20 is in the open state, the rotating head of the drilling device can pass through the first flow channel 210, the second flow channel 220, and the first opening 11 to contact the outside of the shipwreck's oil tank for drilling operations.

[0034] refer to Figure 5 In the closed state, the centerline of the second flow channel 220 intersects with the centerline of the first flow channel 210, and the spherical valve core 22 blocks the first flow channels 210 located on its upper and lower sides. Rotating the spherical valve core 22 relative to the valve housing 21 controls the ball valve mechanism 20 to switch between the open and closed states. When the ball valve mechanism 20 is in the closed state, the spherical valve core 22 blocks the first flow channels 210 located on its upper and lower sides. After the drilling operation is completed, switching the ball valve mechanism 20 to the closed state can seal the oil outlet hole opened on the outside of the oil tank of the sunken ship, preventing oil leakage from the tank.

[0035] When using the drilling bracket 100 provided in this application, the base plate 10 is first fixedly installed on the outside of the oil tank of the sunken ship. Then, the ball valve core 22 of the ball valve mechanism 20 is rotated to switch the ball valve mechanism 20 to the conducting state. Next, the drilling equipment is installed on top of the drilling bracket 100, and the drill bit of the drilling equipment passes through the first flow channel 210, the second flow channel 220, and the first opening 11 to contact the outside of the oil tank of the sunken ship for drilling. After drilling is completed, the drill head of the drilling equipment is pulled out from the first flow channel 210 and the second flow channel 220. Then, the ball valve core 22 is rotated to switch the ball valve mechanism 20 to the closed state to prevent oil leakage from the oil tank.

[0036] The drilling bracket 100 provided in this application can provide a passage for the rotating head of the drilling equipment during the drilling process, prevent the drilling equipment from deviating, and improve the accuracy of the drilling position; after the drilling is completed, the ball valve mechanism 20 is switched to the closed state, which can seal the opened oil outlet and prevent oil leakage in the oil tank.

[0037] refer to Figure 1 and Figure 2Furthermore, the ball valve mechanism 20 further includes a first rotating rod 231 and a second rotating rod 232. The valve housing 21 has a rotation channel 212 at a preset position, which connects the rotation cavity 211 to the outside. One end of the first rotating rod 231 passes through the rotation channel 212 and connects to the spherical valve core 22. The other end of the first rotating rod 231 is connected to the second rotating rod 232, and the second rotating rod 232 and the first rotating rod 231 are staggered. One end of the first rotating rod 231 extending into the rotation cavity 211 is fixedly connected to the spherical valve core 22. Rotating the first rotating rod 231 can drive the spherical valve core 22 to rotate within the rotation cavity 211, thereby controlling the ball valve mechanism 20 to switch between the open state and the closed state. The end of the second rotating rod 231 away from the rotating cavity 211 is connected to the second rotating rod 232, and the first rotating rod 231 and the second rotating rod 232 are staggered. Rotating the second rotating rod 232 can drive the first rotating rod 231 to rotate, which facilitates the operator's operation.

[0038] It should be noted that the spherical valve core 22 is a sphere with the second flow channel 220, the rotating cavity 211 is a spherical cavity, and the radius of the rotating cavity 211 is adapted to the radius of the spherical valve core 22. The cross-sectional shape of both the first flow channel 210 and the second flow channel 220 in the direction perpendicular to the centerline is circular, and the radius of the first flow channel 210 is the same as the radius of the second flow channel 220. The radius of the spherical valve core 22 is larger than the radius of the first flow channel 210.

[0039] Furthermore, the bottom of the valve housing 21 is detachably connected to the base plate 10, and the valve housing 21 includes a first valve housing 213 and a second valve housing 214, which are detachably connected.

[0040] The valve housing 21 is detachably connected to the base plate 10. If either of them is damaged, they can be disassembled, and the damaged workpiece can be replaced, thus improving workpiece utilization. The first valve housing 213 and the second valve housing 214 are detachably connected to each other. This facilitates the placement of the spherical valve core 22 within the rotating cavity 211 and also allows for easy replacement of the spherical valve core 22 should it be damaged.

The valve housing 21 has ear holes 250 penetrating the first lugs 251 and the second lugs 252. The punch bracket 100 further includes a screw (not shown in the figure) installed in the ear hole 250. In some embodiments, the inner wall of the ear hole 250 has threads adapted to the screw, and the screw is passed through the ear hole to fix the first lugs 251 and the second lugs 252 together. In some embodiments, the screw can also be replaced by a rivet. In some embodiments, the first lugs 251 and the second lugs 252 can also be connected by welding, and when disassembly is required, a cutting tool can be used to cut along the connection to separate them.

The limiting blocks 40 surround each other to form a limiting space 41, and the bottom of the drilling device is adapted to be installed in the limiting space 41. The limiting blocks 40 can limit the position of the drilling device installed on the top plate 30, making it easier for the drill bit of the drilling device to be aligned with the second opening 31.

[0047] Specifically, the limiting block 40 is L-shaped, and there are four limiting blocks 40. The four limiting blocks 40 are respectively set at the four corners of the rectangle to limit the drilling device at the four corners of the drilling device.
