The present invention relates to a head cover structure of the core for pumping groundwater, in detail, the head casing to facilitate the assembly and disassembly by configuring the head cover so that the fixing of the lower case and the upper case constituting the head cover by a clamp It's about structure.

In general, the groundwater hole is anchored with an external casing to prevent damage to the inside of the heart after excavation, and a pump pipe is installed therein to extend deep into the heart, and at the end of the pump, the pump is connected to an underwater motor for pumping. The outer casing is projected to a certain height from the ground surface to prevent the sewage of the ground from flowing into the heart, and a separate head cover on the upper end of the exposed outer casing to prevent the inflow of contaminants. Cover the inside and outside of the heart will be made of a configuration.

Conventional head cover is composed of a lower case to cover the upper portion of the outer casing and an upper case covering the upper portion, the upper case is a connection pipe for connecting the positive pipe inside the heart and the external water pipe, depth measurement and inner heart Inspection holes for inspecting and the outside air intake hole is formed, these inspection holes and intake holes are each made of a pipe that protrudes to a predetermined height into the upper case.

The upper and lower cases are fastened using a plurality of bolts in the form of a flange, the filter is coupled to the intake hole, and the inspection port is formed of a bolt-shaped cap so as to be opened when necessary.

The conventional head cover structure is a structure in which the upper and lower cases are fixed by a plurality of bolts coupled to the flange portion, and the bolt holes formed on the flanges of the upper and lower cases must be formed within an error range so that the correct fastening can be made, and the assembly process is performed. Disassembly for the process and post-installation maintenance is very demanding and requires a lot of work time.

That is, in the manufacturing process, the flange is formed on the upper edge of the cylindrical case, and bolt holes are formed at regular intervals on the flange, and the same bolt hole is formed on the corresponding upper case. It is difficult to grasp and it takes a high level of skill, precision and time to form dozens of bolt holes (approximately 12-18) in the upper and lower cases at the correct position. Assembling is done by assembling the pump pipe in the state to the connecting pipe formed in the upper case and assembling the upper and lower cases. The upper case in which the connecting pipe and the underwater motor are combined is very difficult to handle due to its weight. It is difficult to match the bolt hole position of the upper and lower cases.

Even during the maintenance process, when do you want to separate the upper case for the management of the internal submersible motor or the underground vein cleaning, dozens of bolts must be separated every day, so the working time is long and the upper case is not removed. In order to check the depth of water or the degree of contamination, a tool such as a wrench must be used to open the inspection hole, so there was a lot of inconvenience in maintenance such as carrying a heavy tool.

The present invention is designed to facilitate the manufacture, assembly and maintenance by improving the head cover structure of the groundwater core well.

To this end, the present invention proposes a head cover structure of a structure in which the flange portion of the upper and lower cases can be assembled using a circular clamp.
