DETAILED DESCRIPTION

[0017] The utility model is further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by this application.

[0018] In conjunction with the accompanying drawings, a high-pressure hydraulic drilling device includes a drill bit 1 and a connecting tube 2. The drill bit 1 is fixedly arranged on the left side of the connecting tube 2, and a hydraulic motor is fixedly arranged on the right side of the connecting tube 2. This structural design provides a high-pressure water flow for the device. The outer circle of the connecting tube 2 is provided with an array of grooves 101, and each of the grooves 101 is hingedly connected to a first scraper 3. The other end of the first scraper 3 is hingedly connected to a second scraper 10. The connecting tube 2 is provided with a first water channel 4 and a second water channel 5 from left to right in sequence, and a stopper 6 is slidably arranged inside the first water channel 4. A high-pressure water tank 7 and a low-pressure water tank 8 are arranged in an array inside the connecting tube 2, and a valve core 9 is slidably arranged inside the high-pressure water tank 7 near the right end.

[0019] The left end of the first scraper 3 is hinged to the left end of the inner wall of the groove 101, and a first magnet 301 is fixedly arranged on the inner side of the first scraper 3 near the right end, and a second magnet 103 is fixedly arranged on the bottom of the inner wall of the groove 101 near the right end. When the drill bit 1 is working, the first magnet 301 and the second magnet 103 are attracted to each other, and the first scraper 3 is limited by this structural design.

[0020] The right end of the high-pressure water tank 7 is connected to the second water channel 5 and the left end is connected to the corresponding groove 101. A water outlet groove 701 is opened on the high-pressure water tank 7. The top of the water outlet groove 701 is connected to the groove 101 and the bottom is connected to the first water channel 4. The water outlet groove 701 is located between the right side of the block 6 and the inner wall of the first water channel 4. The top of the valve core 9 is fixedly connected to the inner wall of the right end of the high-pressure water tank 7 through the second spring. The bottom of the valve core 9 is flush with the inner wall of the second water channel 5. The high-pressure water flow is sprayed out from the left end of the high-pressure water tank 7 and the top of the water outlet groove 701.

[0021] The low-pressure water tank 8 connects the first water channel 4 and the second water channel 5. The right side of the stopper 6 is fixedly connected to the inner wall of the first water channel 4 through a first spring. A stopper ring 102 is fixedly arranged near the middle position of the inner wall of the first water channel 4. When the drill bit 1 advances to drill a hole, the left end of the low-pressure water tank 8 is located between the stopper ring 102 and the stopper 6.

[0022] The outer ring of the connecting tube 2 is provided with a slide groove 104 in an array near the right end of the groove 101, the other end of the second scraper 10 abuts against the inner wall of the slide groove 104 and protrusions 1001 are symmetrically arranged on both sides, and the two side walls of the slide groove 104 are symmetrically provided with rectangular grooves, and the protrusions 1001 abut against the rectangular grooves. Through this structural design, the movement trajectory of the second scraper 10 can be limited.

[0023] When the device is in use, the device is connected to the mining drill rod. During normal drilling operation, low-pressure water flow is connected to the left end of the connecting tube 2, and the water flows into the second water channel 5. Since the water pressure is too low to push open the valve core 9, the water flows through the low-pressure water tank 8 into the first water channel 4, thereby cooling the working drill bit 1; the left end of the connecting tube 2 is connected to high-pressure water flow, and the valve core 9 is pushed upward due to the high water pressure. A part of the high-pressure water flow enters the first water channel 4 through the outlet groove 701, and the high-pressure water flow pushes the block 6 to move to the left and abut against the retaining ring 102, thereby blocking the water from entering the left end of the low-pressure water tank 8, and the other part of the high-pressure water flow flows out through the left end of the high-pressure water tank 7 and the top of the outlet groove 701 to gradually push open the first scraper 3, and at the same time drives the second scraper 10 to move to form a triangle with the first scraper 3, which is beneficial to the stability of the structure; the ejected high-pressure water flow flushes the inner wall of the borehole.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
