An underground water well protection device is provided to prevent the inflow of surface water under the ground through a main pipe and to heighten hermetic capacity by connecting a connection passage of a suspension member with a discharge pipe. An underground water well protection device for preventing an underground water well from being polluted by surface water or pollutants and preventing a leakage of water when taking in underground water comprises a tubular main body connected with a main body(100) for taking in underground water and located in a manhole or exposed to the surface of the earth, a cover member(21) coupled with the upper part of the main body to seal up the tubular main body, a discharge pipe(200) installed to the outer circumferential surface of the tubular main body to discharge underground water, and a discharge guide device(30) installed to the inside of the tubular main body to support an intake pipe(300) coupled with an underwater pump(310) for taking in underground water and discharging the underground water from the intake pipe to the discharge pipe. The discharge guide device includes a support member(35) provided with a first guide portion(31) installed vertically to the inner circumferential surface of a main body of a connection of the discharge pipe and a second guide portion(32) installed to the inner circumferential surface of the tubular main body corresponded to the first guide portion and inclined toward the first guide portion, and a suspension member(40) supported by the first and second guide portions and provided with a pressure incline portion(41) corresponded to the second guide portion, an adhesion portion(42) adhered closely to the first guide portion and a connection passage(43) connecting the intake pipe and the discharge pipe. |
