Wireless water pressure transmission device

The invention discloses a wireless water pressure transmission device, and belongs to the technical field of water pressure measurement. The wireless water pressure transmission device comprises a positioning seat, the top of the positioning seat is provided with a wireless pressure detection assembly, and the position, corresponding to the wireless pressure detection assembly, of the top of the positioning seat is fixedly connected with an outer protection assembly. According to the invention, under the mutual cooperation of the designed wireless pressure detection assembly, an outer protection assembly, a drainage mechanism, a pressurization mechanism, a pressure conversion assembly and other structures, a stainless steel shell, a pressure sensing stainless steel film and a water pressure sensor are prevented from being retested, and hardening formed on the surface of the pressure sensing stainless steel film due to long-term monitoring and affecting the precision and the sensitivity of water level measurem
