[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 5 As shown,

[0023] Example 1:

[0024] A high-pressure hydraulic drilling device includes a water drill 1, a drill bit 2 fixedly installed at the output end of the water drill 1, a water inlet 3 fixedly connected to the bottom of the water drill 1 for connection to a high-pressure water pipe, and a housing 4 fixedly connected to the top of the water drill 1, with a protective mechanism provided on the top of the housing 4.

[0025] The protective mechanism includes a protective cover 5. One side of the protective cover 5 has a through hole 6 for use with the drill bit 2. A guide rod 7 is fixedly connected to one side of the protective cover 5. Two L-shaped blocks 8 are symmetrically arranged on the top of the housing 4. A U-shaped block 9 is fixedly connected to the side of the two L-shaped blocks 8 that is close to each other. A guide wheel 10 is rotatably connected to the inner wall of the U-shaped block 9. A guide groove 11 for use with the guide wheel 10 is opened on the surface of the guide rod 7.

[0026] The disassembly mechanism is movably mounted on the housing 4.

[0027] In this embodiment, a protective mechanism is set up. When in use, the drill bit 2 is brought into contact with the ground, and then the guide rod 7 is pushed. The guide rod 7 will slide under the restriction of the guide wheel 10 and the guide groove 11, so that the protective cover 5 is also brought into contact with the ground. Then the water drill 1 is started to drive the drill bit 2 to drill a hole in the ground. The splashed mud and sand will be isolated by the protective cover 5 and will not accidentally injure the workers.

[0028] It should be noted that the drill bit 2 and the protective cover 5 do not come into contact, so it will not affect the normal rotation of the drill bit 2. At the same time, as the drill bit 2 gradually rises into the ground, the protective cover 5 will also gradually push backward, but always remain in contact with the ground.

[0029] The top of the protective cover 5 is provided with an observation window 19, and the inner wall of the observation window 19 is fixedly embedded with tempered glass 20.

[0030] In this embodiment, by setting up an observation window 19 and tempered glass 20, the user can watch the drill bit 2 drilling through the tempered glass 20, thus avoiding the protective cover 5 from affecting the staff's observation.

[0031] Example 2:

[0032] Based on Embodiment 1, the protective cover 5 in the protective mechanism of this embodiment can prevent mud and sand from splashing. However, considering that the protective cover 5 may affect normal drilling under some special circumstances, it needs to be disassembled. The disassembly mechanism in this application includes a bidirectional lead screw 12 disposed inside the housing 4. The surface of the bidirectional lead screw 12 is connected to two transmission blocks 13. The top of the transmission block 13 is fixedly connected to a sliding block 14. The top of the sliding block 14 is fixedly connected to the bottom of the L-shaped block 8. One end of the bidirectional lead screw 12 extends through to the outside of the housing 4 and is fixedly connected to a turning block 15.

[0033] In this embodiment, a disassembly mechanism is provided. When the protective cover 5 needs to be disassembled, the screwing block 15 can be rotated. The screwing block 15 will drive the bidirectional lead screw 12 to rotate. At the same time, the bidirectional lead screw 12 will drive the two transmission blocks 13 to move to the side away from each other. The transmission blocks 13 will drive the sliding block 14, L-shaped block 8, U-shaped block 9 and guide wheel 10 to move, so that the guide wheel 10 leaves the inside of the guide groove 11. At this time, the protective cover 5 can be pushed to the side closer to the drill bit 2, and the protective cover 5 can be removed, which facilitates disassembly.

[0034] It should be noted that the installation process is the reverse of the above steps. The drill bit 2 is passed through the through hole 6, and then the guide rod 7 is moved to the top of the two L-shaped blocks 8. The twisting block 15 is rotated in the opposite direction to allow the guide wheel 10 to enter the guide groove 11 to restrict the guide rod 7 and the protective cover 5.

[0035] One end of the bidirectional lead screw 12 is provided with a bearing 16, and is rotatably connected to the inner wall of the housing 4 through the bearing 16.

[0036] In this embodiment, by setting the bearing 16, the bidirectional lead screw 12 can be supported, while restricting it to rotate only around the bearing 16.

[0037] The top of the housing 4 is provided with a sliding groove 17, which is used in conjunction with the sliding block 14.

[0038] In this embodiment, by setting a sliding groove 17, when the bidirectional lead screw 12 rotates to transmit power to the transmission block 13 and the sliding block 14, it can only move along the trajectory of the sliding groove 17.

[0039] The circumferential side of the rotating block 15 is provided with anti-slip texture 18, and the number of anti-slip texture 18 is several.

[0040] In this embodiment, by setting anti-slip texture 18, it is easy for the user to drive the bidirectional lead screw 12 to rotate, and at the same time, it can play an anti-slip role.

[0041] Working principle: When in use, drill bit 2 is brought into contact with the ground, and then guide rod 7 is pushed. Guide rod 7 will slide under the restriction of guide wheel 10 and guide groove 11, so that protective cover 5 also comes into contact with the ground. Then, water drill 1 is started to drive drill bit 2 to drill holes in the ground. The mud and sand that splash out will be isolated by protective cover 5 and will not injure the workers.

[0042] When it is necessary to disassemble the protective cover 5, the screwing block 15 can be rotated. The screwing block 15 will drive the double-acting screw 12 to rotate. At the same time, the double-acting screw 12 will drive the two transmission blocks 13 to move to the side away from each other. The transmission blocks 13 will drive the sliding block 14, L-shaped block 8, U-shaped block 9 and guide wheel 10 to move, so that the guide wheel 10 leaves the inside of the guide groove 11. At this time, push the protective cover 5 towards the side closer to the drill bit 2, and the protective cover 5 can be removed, which facilitates disassembly.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
