When in use, the operator holds the first handle 12 with the hand. A first switch 121 is provided on the first handle 12. When the operator holds the first handle 12, he presses the first switch 121 with one finger to start the water drill, and the water drill stops working when the finger releases the first switch 121.
[0037] Referring to Figure 2 and Figure 3A water supply device 3 is provided on one side of the machine body 1 parallel to the moving direction of the drill bit 2. When the water drill is working, the drill bit 2 is cooled by the water supply device 3. The water supply device 3 includes a first bracket 31, a bottle body 32 and a bottle cap 33. One end of the first bracket 31 is inserted into the machine body 1. The first bracket 31 can rotate on the machine body 1. The bottle body 32 is provided with a bottle body 321, an inclined portion 322 and a bottle mouth 323 from top to bottom. A water inlet pipe 4 is inserted into the bottle cap 33. Cooling water enters the water inlet pipe 4 from the bottle body 32 under the action of gravity. A connecting tube 51 is sleeved on the end of the water inlet pipe 4 away from the bottle cap 33. The water inlet pipe 4 is detachably connected to the connecting tube 51, and the water inlet pipe 4 can be pulled out from the connecting tube 51. A cover body 5 is provided at one end of the connecting tube 51 away from the water inlet pipe 4. The end of the connecting tube 51 away from the water inlet pipe 4 extends into the cover body 5 and is fixedly connected to the cover body 5. When the water inlet pipe 4 is inserted into the connecting tube 51, cooling water flows into the cover body 5. Through openings for the drill bit 2 to pass through are provided at both ends of the cover body 5. The cover body 5 is sleeved on the outside of the drill bit 2, and the drill bit 2 extends from the through opening of the cover body 5. When the water drill is working, the drill bit 2 extends into the wall, and the cover body 5 moves toward the machine body 1 relative to the drill bit 2. The movement of the cover body 5 drives the water inlet pipe 4 to bend.
[0038] Reference Figure 3 and Figure 4 A water spray pipe 52 is inserted into one end of the connecting tube 51 close to the inside of the cover body 5 , and the cooling water entering the cover body 5 through the connecting tube 51 is sprayed onto the drill bit 2 from the nozzle of the water spray pipe 52 .
[0039] When the bottle 32 is in use, after the bottle mouth 323 passes through the first bracket 31 upward, the bottle cap 33 is threadedly connected to the bottle mouth 323 to seal the bottle body 32, and the first bracket 31 and the bottle body 32 are rotated 180 degrees together. At this time, the opening direction of the bottle mouth 323 is downward, and the second bracket 34 is sleeved on the bottle body 321. After the bottle body 32 is lifted up, the bottle cap 33 is away from the first bracket 31, and the water inlet pipe 4 is bent and abutted against the first bracket 31. At this time, the second bracket 34 moves downward along the bottle body 321, and one end of the second bracket 34 is inserted into the plug ring 13 fixedly arranged on the surface of the body 1. When the second bracket 34 and the first bracket 31 are concentric along the axis direction of the bottle body 321, the bottle body 32 is placed on the first bracket 31, and the first bracket 31 abuts against the inclined portion 322. The inclined portion 322 is in the shape of a cone with a diameter decreasing from top to bottom. The bottle body 32 will not detach from the middle of the first bracket 31, and the second bracket 34 increases the stability of the bottle body 32.
[0040] When the water drill is in use, the operator holds the first handle 12, inserts the drill bit 2 through the opening of the cover body 5, and extends it out from the other opening. Then, the operator turns on the first switch 121, and the drill bit 2 starts to drill a hole in the wall. The drill bit 2 slowly drills into the wall while the cover body 5 remains stationary. The drill bit 2 continuously rotates and rubs against the wall, causing the surface temperature of the drill bit 2 to rise. Cooling water enters the spray pipe 52 along the water inlet pipe 4 from the water supply device 3 and is sprayed onto the drill bit 2 to cool it down. There is no need for another person to add water to cool the rotating drill bit 2, which reduces the number of workers and lowers the cost.
[0041] Refer to Figure 1 and Figure 3 , a pressing ring 54 is provided at one end of the cover body 5 away from the machine body 1, which increases the contact area between the cover body 5 and the wall, makes the cover body 5 fit more closely to the wall surface, confines the cooling water inside the cover body 5, reduces the degree of dirt on the outer wall of the cover body 5, shortens the time for cleaning the wall, improves the efficiency. A water baffle 53 is provided on the inner wall of the cover body 5. The cooling water sprayed onto the drill bit 2 flows onto the inner wall of the cover body 5 and is blocked by the water baffle 53. An outlet pipe 55 is provided on the cover body 5. The inner wall of the outlet pipe 55 is tangent to the side of the water baffle 53 away from the machine body 1. The outlet pipe 55 is arranged vertically downward. The cooling water blocked by the water baffle 53 flows out of the cover body 5 through the outlet pipe 55. The end of the outlet pipe 55 away from the cover body 5 is connected to a pipeline 58 to convey the cooling water to a recovery bucket.
[0042] Refer to Figure 1 , a number of guide rods 56 are provided at one end of the cover body 5 close to the machine body 1. A guide groove corresponding to each guide rod 56 is opened on one side of the machine body 1 close to the cover body 5. One end of the guide rod 56 is inserted into the inside of the guide groove, and the guide rod 56 drives the cover body 5 to be slidably connected to the machine body 1. A spring 57 is sleeved on the outer wall of the guide rod 56. One end of the spring 57 can be fixedly connected to the cover body 5. When the cover body 5 is removed and the guide rod 56 slides out of the guide groove, the spring 57 will not slip off the guide rod 56, reducing the assembly time. During use, one end of the cover body 5 abuts against the wall, the guide rod 56 at the other end of the cover body 5 is inserted into the guide groove, and the end of the spring 57 away from the cover body 5 abuts against the machine body 1. As the drill bit 2 drills into the wall, the spring 57 is continuously compressed, and the elastic force of the spring 57 strengthens the degree of fit between the cover body 5 and the wall. The guide rod 56 increases the stability of the cover body 5. At the same time, the operator does not need to hold the cover body 5 when the water drill is working and can hold the first handle 12 with both hands, increasing the force required for the drill bit 2 to move deeper into the wall.
[0043] Refer to Figure 1 and 2, on one side of the machine body 1 parallel to the moving direction of the drill bit 2, a second handle 15 is threadedly connected. The operator operates the water drill with both hands, making the operation more labor-saving, safe and stable. Threaded sleeves 16 are provided on both sides of the machine body 1, and the second handle 15 is threadedly connected to the threaded sleeves 16, adapting to the usage habits of different operators and also adapting to the usage conditions of different sites.
[0044] Refer to Figure 1 and 2 , a second switch 41 for controlling the water flow is provided on the water inlet pipe 4. When the water drill stops working, first close the second switch 41 and then take out the drill bit 2 from the wall, reducing the pollution to the wall surface and also reducing the waste of water. A fixing ring 411 is provided on the second switch 41, and the fixing ring 411 is rotatably connected to the second handle 15. When in use, when the second handle 15 is threadedly connected to the threaded sleeve 16, the second switch 41 will not rotate together with the second handle 15, and the water inlet pipe 4 will not be wound around the second handle 15. The operator can control the second switch 41 while holding the second handle 15, making the operation simpler.
[0045] The implementation principle of a water drill according to an embodiment of the present application is as follows: When the water drill is in use, the operator presses the cover body 5 tightly against the position on the wall where drilling is required with one hand, and holds the first handle 12 with the other hand. Insert the drill bit 2 into the through hole of the cover body 5 and extend it out from the other through hole. At this time, the guide rod 56 is inserted into the guide groove, and the spring 57 abuts against the machine body 1. Press the second handle 15 with the hand holding the cover body 5, turn on the first switch 121, and the drill bit 2 starts drilling on the wall surface. The drill bit 2 slowly drills into the wall, the cover body 5 remains stationary, the drill bit 2 continuously rotates and rubs against the wall, the temperature on the surface of the drill bit 2 rises, and the cooling water enters the spray pipe 52 along the water inlet pipe 4 from the water supply device 3 and is sprayed onto the drill bit 2, then flows to the inner wall of the cover body 5 and is blocked by the water baffle 53, and then flows into the recovery bucket from the water outlet pipe 55.
[0046] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
