Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

It should be understood that the present invention uses the terms "front", "back", etc. to describe various information, but the information should not be limited to these terms, and these terms are only used to distinguish one type of information from another. For example, "front" information may also be referred to as "back" information, and "back" information may also be referred to as "front" information without departing from the scope of the present invention. The embodiment of the utility model provides an in, define the well lid as the inboard towards one side of valve well, define the outside towards one side in the external world with the well lid.

As shown in figures 1 and 2, the utility model provides a protective well lid, which comprises a well lid body 1, wherein the well lid body 1 is provided with a vent hole 11, the inner side wall of the well lid body 1 is provided with an annular boss 2 communicated with the vent hole 11, gas can enter the annular boss 2 through the vent hole 11 and enter a valve well along the annular boss 2, the diameter of the annular boss 2 is larger than the diameter of the vent hole 11, so that enough space is ensured around the vent hole 11, a maintainer can conveniently arrange a cover opening tool such as a grab hook on the vent hole 11, a collecting disc 3 is arranged below the annular boss 2, the collecting disc 3 is fixedly connected with the well lid body 1, the collecting tray is used for collecting impurities such as silt and accumulated water entering from the air holes 11, a hole sealing ball 4 is arranged in the collecting tray 3, the diameter of the hole sealing ball 4 is larger than that of the annular boss 2, and the hole sealing ball 4 is partially arranged in the annular boss 2.

Based on the structure, when in use, the hole sealing ball 4 is placed in the collecting tray 3, the collecting tray 3 is fixedly connected below the annular boss 2, and partial ball body of the hole sealing ball 4 is ensured to go deep into the annular boss 2, when impurities such as accumulated water or silt enter the valve well through the air holes 11, the collected tray 3 firstly reaches the collecting tray 3, the collected tray 3 blocks and collects the impurities to avoid the impurities from continuously entering the valve well to damage the gas valve, along with the increase of the impurities in the collecting tray 3, the water surface in the collecting tray 3 rises or the silt is accumulated and thickened, the hole sealing ball 4 is also lifted upwards along with the impurities and abuts against the bottom of the annular boss 2 to seal the annular boss 2, more impurities are prevented from entering the valve well, the effects of sealing the air holes 11 and reminding a maintainer to clean the collecting tray 3 are achieved, and meanwhile, the impurities in the collecting tray 3 are prevented from continuously accumulating and overflowing out of the collecting tray 3 to influence the gas valve in the valve well, when the collecting tray 3 is full of impurities, a maintainer opens the well cover to detach the collecting tray 3, so that the impurities in the collecting tray 3 are cleaned, and the normal use of the collecting tray 3 is ensured.
