The invention discloses an underwater fused trigger-type release hook device which is installed on a sea base system. The underwater fused trigger-type release hook device comprises a support, a hook rod, an electrolytic wire and an electrode post. The support is of an inverted U-shaped framework structure, the hook rod is installed on the lower part of the support by virtue of a rotating shaft, the hook rod comprises a square rod, a circular rod and a hook on the head part of the square rod, which are connected into a whole body; the hook of the hook rod is connected with a counterweight part of the sea base system, the circular rod of the hook rod is connected with a positive electrode of the electrode post by virtue of the electrolytic wire sleeving the tail part, and a negative electrode post and a positive electrode post of the electrode post are installed at the other side of the support. The electrolytic wire straining the hook rod is rapidly fused after a control device outputs a direct-current control voltage, the hook is triggered to be loosened, and the counterweight part is released, so that a floating part on the sea base system floats on the water surface under the effect of self floating force, and the recycling of underwater equipment is realized. No moving part is needed during the fusing process of the electrolytic wire, so that not only is the structure simplified, but also the release recycling reliability and environmental applicability of the sea base system are improved.
