The invention relates to a small amount of water for a natural gas well and a solid bubble discharging device for a natural gas well. The utility model can solve the problems that the traditional solid foaming agent has the disadvantages of complicated working procedure, large labor intensity, high cost of producing gas, and irregular delivery cycle of the solid foaming agent. The technical scheme is: and welded on the shell is installed above the upper cover, and welded on the shell is arranged below the lower cover; the rotating shaft is installed in the closed space formed by the upper cover and the shell and the lower cover, the lower end of the rotating shaft passes through the lower cover out of confined space; the upper limit and lower limit wheel wheel installed in the casing and the key is connected with the rotating shaft, placed in the upper limit loading agent cylinder wheel and the lower wheel; the driving gear by gear, gear and pawl spring sleeve, an inner sleeve; linear motor is arranged on the lower cover bottom right, linear motor and automatic timing control system in parallel. The invention realizes the automation of the solid foam discharging agent, reduces the labor intensity, reduces the human resource, utilizes the solar energy to provide electric energy, and saves energy and environment.
