The invention relates to a hydroelectric generation device, in particular to a shipborne type hydroelectric generation device which is capable of generating electricity by using current kinetic energy. The shipborne type hydroelectric generation device is composed of a main load bearing ship, auxiliary load bearing ships, water wheels, a support, a water wheel lifting mechanism, a power transmission mechanism and an electric generator. According to the support, the main load bearing ship and the auxiliary load bearing ships are fixed on a middle section and the two sides under the support by a support platform and support vertical rods. The electric generator is installed on the main load bearing ship. Two water wheels are respectively installed on the two sides of the main load bearing ship. The auxiliary load bearing ships are arranged at the outer sides of the water wheels. An anchor pile, a mooring rope and a plurality of shipborne type hydroelectric generation devices are combined into a hydroelectric generation station. Compared with the prior art, the shipborne type hydroelectric generation device is free from the need of building a dam, small in occupation of land, short in time of construction, small in investment, large in single-machine power, reliable in working performance, good in stability, wide in application range and good in development and utilization of water power resources.

The invention relates to a water block which comprises a water-cooled shell provided with a concave section. A horizontally arranged cooling cavity and a liquid inlet cavity and a liquid outlet cavity are formed in the water-cooled shell, the liquid inlet cavity and the liquid outlet cavity are vertically arranged, a round liquid inlet pipe is arranged in the upper end of the liquid inlet cavity, and a round liquid outlet pipe is arranged in the upper end of the liquid outlet cavity; a bottom plate of the water-cooled shell is of a cooling bottom plate, at least two sets of cooling fins are arranged on the cooling bottom plate, and the distance between upper ends of the cooling fins and the top wall of the cooling cavity is 1-3mm; a first water wheel is arranged at the bottom of the liquid inlet cavity, and a second water wheel is arranged at the bottom of the liquid outlet cavity. When waterflow flows among the liquid inlet cavity, the liquid outlet cavity and the cooling cavity, water flow at positions of dead space on two lower sides of the water-cooled body can be driven to flow by the aid of the water wheels in the water-cooled shell, and cooling capacity of the water block is improved.
