[0002] In construction, water drills are commonly used to create openings in concrete walls. Especially when drilling holes at the top or from the bottom up, water is used to pass through the drill bit, which lowers the drill bit's temperature and flushes out debris from the hole. However, if this debris isn't collected promptly, it and the wastewater will flow into the drill's motor. Utility Model Content
[0003] The purpose of this invention is to provide a waterproof structure for water drills to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a waterproof structure for a water drill, including a water receiving tray, wherein a transmission component is provided in the middle of the water receiving tray; the transmission component includes a fixed frame, and a transmission shaft is rotatably installed inside the fixed frame; after the fixed frame is fixed on the water receiving tray, the drill bit of the water drill is installed at one end of the transmission shaft, and the output shaft of the water drill is connected to the other end of the transmission shaft; when the transmission shaft drives the drill bit to open a hole, the water receiving tray is used to receive the water flow below the drill bit.
[0005] As a preferred technical solution of this utility model: the water receiving tray is further provided with a corrugated pipe, and the corrugated pipe is used to cover the outside of the drill bit to guide the water flow to the water receiving tray.
[0006] As a preferred technical solution of this utility model, the water receiving tray is also provided with a drain pipe.
[0007] As a preferred technical solution of this utility model: one end of the drain pipe passes through the water receiving tray and is connected to the provided second nut; there are two second nuts, and the drain pipe is fixed on the water receiving tray by tightening the two second nuts on both sides of the water receiving tray.

[0021] Please see Figure 1-4 This utility model provides an embodiment of a waterproof structure for a water drill, including a water receiving tray 1. A transmission assembly 3 is located in the middle of the water receiving tray 1. The transmission assembly 3 includes a fixing frame 30, and a transmission shaft 31 is rotatably mounted within the fixing frame 30. After the fixing frame 30 is fixed to the water receiving tray 1, the drill bit of the water drill is mounted on one end of the transmission shaft 31, and the output shaft of the water drill is connected to the other end of the transmission shaft 31. When the transmission shaft 31 drives the drill bit to drill, the water receiving tray 1 collects the water flow below the drill bit. Since the transmission shaft can be used to mount the drill bit or connect to the output shaft of the water drill, it prevents sewage from flowing towards the motor when the drill bit rotates. In particular, this device can be directly connected to the water drill, thus eliminating the need for additional water receiving equipment. This simplifies the structure while preventing sewage leakage, thereby improving drilling efficiency.
[0022] Furthermore, the water receiving tray 1 is also provided with a corrugated pipe 8, which is used to cover the outside of the drill bit to guide the water flow to the water receiving tray 1.
[0023] In summary, since the drive shaft 31 can be used to mount the drill bit or connect to the output shaft of the water drill, for example, by connecting the upper end of the drive shaft 31 to the drill bit using an external thread and the lower end to the output shaft of the water drill using an internal thread, or by connecting it to the output shaft of the water drill using a plane on its outer wall (the specific connection method is consistent with existing methods), when the drill bit rotates, the corrugated pipe 8 guides the wastewater to flow into the water receiving tray 1, thus preventing wastewater from splashing onto the drilling personnel and preventing wastewater from flowing into the motor, which could cause leakage or short circuit in the water drill. In particular, this device can be directly connected to the water drill, thus eliminating the need for additional water receiving equipment. This simplifies the structure while preventing wastewater leakage, thereby improving drilling efficiency.
[0024] Furthermore, since the water receiving tray 1 is also equipped with a drain pipe 2, sewage can be discharged in a timely manner, preventing sewage leakage and reducing the weight of the water drill, thereby increasing the user's continuous working time. Specifically, one end of the drain pipe 2 passes through the water receiving tray 1 and connects to a second nut 7; there are two second nuts 7, which are tightened on both sides of the water receiving tray 1 to fix the drain pipe 2 to the water receiving tray 1. This makes the drain pipe 2 not only easy to install but also easy to replace, and in particular, it reduces the difficulty of connecting the drain pipe 2 to the water receiving tray 1.
[0025] To prevent the corrugated pipe 8 from automatically shrinking under its own weight, the side of the corrugated pipe 8 away from the water receiving tray 1 is fixedly connected to a bracket 9. Thus, the bracket 9 can be used to position the corrugated pipe 8, ensuring that the upper end of the corrugated pipe 8 fits as close to the wall as possible, thereby reducing sewage leakage.
[0026] To prevent the water receiving tray 1 from rotating with the transmission assembly 3, a stop bar 5 is provided on the outer circumference of the water receiving tray 1. When one end of the stop bar 5 abuts against the bracket 9, it prevents the water receiving tray 1 from rotating. One end of the stop bar 5 passes through the circumference of the water receiving tray 1 and connects to the first nut 6. This makes the stop bar 5 not only easy to install, but also allows the user to decide whether to install the stop bar 5 according to actual needs.
[0027] Based on the above solution, the drive shaft 31 is also provided with a retaining ring 35, and the first sealing ring 33 is pressed onto the fixed frame 30 by the retaining ring 35. This can prevent sewage from flowing through the outer wall of the drive shaft 31 toward the water drill motor, thereby ensuring the safety of the motor during use.
[0028] Similarly, after the fixing frame 30 is connected to the water receiving tray 1, the second sealing ring 4 is used to seal the facing surfaces of the water receiving tray 1 and the fixing frame 30, thereby preventing sewage from flowing to the motor along the connection between the water receiving tray 1 and the fixing frame 30.
[0029] To ensure reliable and stable rotation of the drive shaft 31, a bearing 32 is provided inside the fixing frame 30, and one end of the drive shaft 31 passes through the bearing 32 to realize the rotation of the drive shaft 31 within the fixing frame 30. In addition, the bearing 32 not only ensures the normal rotation of the drive shaft 31, but also reduces the runout of the drive shaft 31 during rotation.
[0030] In addition, the drive shaft 31 is provided with a slot 36. After the slot 36 passes through the bearing 32, it connects with the provided retaining ring 34 to confine the drive shaft 31 within the fixing frame 30. This allows the drive shaft 31 to be easily and conveniently installed within the fixing frame 30.
[0031] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
