[0023] In the embodiment of the utility model, please refer to Figures 1 to 4 The outer ring wall of well lid 1 is fixedly embedded with annular elastic air bag 2, and the annular elastic air bag 2 is installed with air cock 21, since the outer ring wall of well lid 1 is provided with annular elastic air bag 2, so that annular elastic air bag 2 is elastically expanded by inflating air cock 21, so that annular elastic air bag 2 is in close contact with the well mouth inner wall of recharge well, so that well lid 1 and annular elastic air bag 2 are mutually matched and realize the plugging of well mouth;

[0024] The bottom of well lid 1 is fixedly installed with guide pipe 3, and the top of well lid 1 is fixedly installed with installation shell body 4 communicated with guide pipe 3, the top of installation shell body 4 is fixedly installed with sound-light alarm 5, and the inner top wall of installation shell body 4 is fixedly installed with touch switch 51 electrically connected with sound-light alarm 5, the trigger component 6 for opening and closing touch switch 51 is installed in guide pipe 3, and the trigger component 6 includes float ball 61, float ball 61 is located in guide pipe 3 and is slidably connected with guide pipe 3, and the upper spherical surface of float ball 61 is fixedly installed with guide rod 62, the top of guide rod 62 is fixedly installed with abutting column 63, and a plurality of piston discs 64 are fixedly sleeved on guide rod 62 between float ball 61 and abutting column 63, and piston disc 64 is slidably connected with guide pipe 3.

[0025] The bottom of guide pipe 3 is of sealed structure, and a plurality of annularly distributed liquid inlet holes 3a are formed in the pipe wall close to the bottom of guide pipe 3.

[0026] Need to explain is: when the water in the recharge well rises, the water enters the guide pipe 3 through the liquid inlet hole 3a and drives the floating ball 61 to float along the guide pipe 3, because the floating ball 61 is located in the guide pipe 3, so the floating ball 61 has stable lifting movement track, with the rising of the water, the floating ball 61 is constantly floated, after the water level of the recharge well reaches the early warning value, the abutting column 63 is inserted into the mounting shell 4 and abuts the touch switch 51, so that the sound and light alarm 5 can give early warning, the staff can stop recharge after receiving the signal, prevent the water overflow in the recharge well, compared with the prior art, the application avoids the risk of false alarm caused by water flow fluctuation, and ensures timely alarm when the water level reaches the early warning value.

[0027] Wherein, since the guide rod 62 is provided with the piston disc 64 which is slidably connected with the guide pipe 3, the water can be prevented from penetrating through the piston disc 64 and entering the mounting shell 4, and the piston disc 64 can make the guide rod 62 stably stand, thereby effectively ensuring that the abutting column 63 can abut the touch switch 51.
