The invention belongs to the technical field of elevator safety design, and discloses a device for adjusting pure water inflow of a cavity. The device for adjusting the pure water inflow of the cavity comprises a fall protection controller, a power supply, a gravity acceleration sensor, a wireless signal alerter, a force sensor, a wiring harness, a foot board and high pressure springs; the fall protection controller, the power supply, the gravity acceleration sensor and the wireless signal alerter are all sequentially arranged on the upper surface of the top of a lift car, the force sensor is arranged on the lower surface of the top of the lift car, the foot board is arranged at the bottom of the lift car, and the high pressure springs are arranged between the foot board and the lower bottom face of the lift car. According to the device for adjusting the pure water inflow of the cavity, when the fall protection controller monitors that the lift car falls through the gravity acceleration sensor, the fall protection controller controls the wireless signal alerter to be opened and informs rescue workers to arrive in time. The device for adjusting the pure water inflow of the cavity is reasonable in design, simple in structure and suitable for optimal design of a falling detraction system of a vertical elevator.
