The invention belongs to the technical field of underwater transformer testing, and discloses an underwater lifting platform for underwater transformer testing, which comprises a guide rod and a positioning rod, the guide rod and the positioning rod are sleeved with a supporting plate, and floating body structures are fixedly mounted on two sides of the supporting plate. The floating body structure comprises a buoy, the top of the buoy is provided with an exhaust valve, and the bottom of the buoy is provided with an air inlet valve. The battery and the controller are used for controlling opening and closing of the exhaust valve and the air inlet valve to inject air into the floating body structure or exhaust the air, when the air inlet valve is switched on and the exhaust valve is switched off, the air pump injects air into the floating body structure through the air inlet valve, so that water in the floating body structure is discharged, buoyancy of the floating body structure is increased to drive the transformer to rise, and the floating body structure is protected. When the air inlet valve is cut off and the exhaust valve is conducted, air can be exhausted from the exhaust valve through water pressure from the drain pipe, so that buoyancy is reduced, the control process is simple and convenient, and no mechanical vibration exists in the ascending or descending process.

    本发明属于水下变压器测试技术领域,且公开了一种水下变压器测试用水下升降平台,包括导杆和定位杆,所述导杆和定位杆套设有托板,所述托板的两侧均固定安装有浮体结构物,所述浮体结构物包括有浮筒且浮筒的顶部安装有排气阀且底部安装有进气阀。本发明通过电池及控制器控制排气阀和进气阀的通止来向浮体结构物的内部注入空气或者将空气排出,将进气阀导通排气阀截止时,气泵通过进气阀向浮体结构物的内部注气,从而将浮体结构物中的水排出,增大其浮力带动变压器上升,截止进气阀导通排气阀便可以通过来自排水管处的水压将气体从排气阀排出,从而减小浮力,控制过程简便,且在上升或者下降过程中无机械振动。
