Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings, but the present invention is not limited to these embodiments, and any modifications or replacements within the basic spirit of the embodiments still fall within the scope of the present invention claimed in the claims.

Example (b): as shown in fig. 1 and 2, a drilling apparatus for automatically controlling water inflow includes a drilling faucet including an upper cover 1, a housing 2, and a central pipe 7. The upper cover with the shell spiro union just the upper cover with the shell has constituted cavity 10, the center tube by the casing bottom is deepened in the cavity and is connected through bearing 8 with the cavity inner wall, be provided with on the upper cover outer wall with the communicating inhalant canal of cavity, inhalant canal includes inlet tube 3. The inlet tube is vertical to stretch into in the cavity, the inlet tube stretches out cavity part and sets up for the level, is convenient for be connected with the water pump. In addition, the part of the water inlet pipe extending into the chamber is provided with a gap 9 which is gradually reduced from the bottom to the top. And a float mechanism is arranged in the cavity and positioned at the lower part of the water inlet pipe, and the float mechanism is opposite to the bottom of the water inlet pipe. The float mechanism comprises a convex seat 4 arranged on the inner wall of the cavity, a spring 5 is vertically arranged on the seat, one end of the spring is fixedly connected with the seat, and the other end of the spring is connected with a spherical float 6.

In this embodiment, a spring installation groove is formed in the seat, one end of the spring 5 is installed in the installation groove to be fixed, an installation hole is formed in the spherical floater, and the other end of the spring is inserted into the installation hole. In addition, the elastic coefficient and the specification of the spring are selected according to the requirement of water inflow. In this embodiment, the diameter of the spherical float 6 is selected to be slightly larger than that of the water inlet pipe, so that the risk that the spherical float is clamped into the water inlet pipe to affect water inlet is avoided. In addition, in the embodiment, the material of the spherical floater can be plastic or hollow steel ball, and the weight of the spherical floater can be designed and selected according to the actual water inflow requirement.

In addition, the gap in this embodiment extends from the bottom diameter of the inlet pipe upwards and gradually towards the outer wall of the inlet pipe. And the notch is an arc-shaped notch from the bottom to the top.

In this embodiment, the height of the arc-shaped notch is 10-35mm, which can be selected from, but not limited to, 10mm, 15mm, 20mm, 30mm or 35 mm.

The drilling faucet of the automatic control water inflow drilling device of the embodiment is adopted. When the spring is in a natural state, the spherical float is positioned at the lower part of the water inlet pipe and is not contacted with the water inlet pipe. At this point, the water flow enters the chamber from the inlet pipe and further enters the bore through the center tube. When the water yield is too big, the water level in the cavity can rise, and the spherical floater rises under the effect of water buoyancy at the moment to shelter from the partial breach of inlet tube, with reduction water yield and water velocity. When the water level is reduced and the spherical floater floats downwards after the water amount is balanced, the spherical floater does not shield the notch, and water can be fed at the maximum flow. When the water quantity is too large and the water level of the cavity is too high, the spherical floater floats upwards to completely block the gap, and water flow cannot enter the cavity. The spherical floater can float downwards to open the gap and then water is fed after the water level in the cavity is reduced. The embodiment can control the shielding range of the spherical floater to the notch at the water inlet pipe according to the water level of the cavity, and the effect of automatically adjusting and automatically controlling the water inflow of the drilling faucet is achieved. The uniformity of the water inlet of the drilling device can be ensured.
