Description

Technical Field

[0001] The present invention relates to a low-water-level catamaran power generation ship, belonging to the technical field of power generation ships. Background Art

[0002] Water energy is the cleanest and most environmentally friendly energy source, an inexhaustible and renewable energy source. The energy availability of water is much greater than that of wind, and it is more stable than wind energy. Wind is determined by nature. When there is wind, power can be generated; when there is no wind, power cannot be generated. Water energy is different. Take the Northeast for example. Except for the 10-day ice run-off period in spring and the 10-day period when winter approaches, calculated as 1 month, there are 11 months of production capacity period. According to the data of the estuary control station and the evaluation of experts, the annual runoff of the Songhua River in Heilongjiang Province is 76.2 billion cubic meters. It can be seen that there is a large development space for the utilization of low water energy. Summary of the Invention

[0007] The purpose of the present invention is to solve the problems existing in the above-mentioned prior art, and further provide a low-water-level catamaran power generation ship.

[0008] The purpose of the present invention is achieved by the following technical solutions:

[0009] A low-water-level catamaran power generation ship, comprising: a debris screen, a first connecting crossbeam of the catamaran, an upper guide vane of the first water turbine, an upper deck of the catamaran, an intermediate suspension beam of the first water turbine, a hydraulic cylinder, a pile for lifting the catamaran, an oil cylinder base, a support crossbeam for the upper guide vane of the first water turbine, a water wheel assembly of the first water turbine, a boom, a suspension assembly, a suspension base, a rear support of the catamaran, a second lower connecting crossbeam of the catamaran, a third lower connecting crossbeam of the catamaran, a fourth lower connecting crossbeam of the catamaran, a high-pressure pump fuel tank of the catamaran, a cabin drainage pump, a gland of the bearing seat assembly of the second water turbine, and the catamaran body. The debris screen is installed at the front end of the catamaran body. The water wheel assemblies of the first and second water turbines are installed in parallel in the middle and rear parts of the catamaran body. The installation height of the water wheel assembly of the second water turbine is lower than that of the water wheel assembly of the first water turbine, and the water wheel assembly of the second water turbine is located behind the water wheel assembly of the first water turbine. An upper guide vane of the first water turbine is installed on the upper part of the front side of the catamaran body. A first connecting crossbeam of the catamaran is installed in the front part of the catamaran body. The second lower connecting crossbeam, the third lower connecting crossbeam, and the fourth lower connecting crossbeam of the catamaran are installed on the bottom of the catamaran body from front to back. The upper part of the catamaran body is covered by the upper deck of the catamaran. Four hydraulic cylinders are installed on the upper deck of the catamaran in a rectangular distribution. A suspension base is installed on the upper deck of the catamaran between the two hydraulic cylinders on the left side. A suspension assembly is installed on the suspension base, and a boom is installed on the suspension assembly. Another suspension base is installed on the upper deck of the catamaran between the two hydraulic cylinders on the right side. A suspension assembly is installed on the suspension base, and a boom is installed on the suspension assembly. The rear support of the catamaran is installed under the upper deck of the catamaran at the rear part of the catamaran body. A cabin water injection port is provided on each of the left and right sides of the rear upper deck of the catamaran. Two cabin drainage pumps are evenly distributed at the rear part of the upper deck of the catamaran. Double catamaran front anchor holes are provided on both sides of the front part of the catamaran body. An intermediate suspension beam of the first water turbine is fixed inside the catamaran body behind the first connecting crossbeam of the catamaran. A support crossbeam for the upper guide vane of the first water turbine is fixed to the lower part of the rear end of the upper guide vane of the first water turbine. The high-pressure pump fuel tank of the catamaran is installed on the lower side of the upper deck of the catamaran at the front part of the catamaran body. The oil cylinder base is installed on the upper deck of the catamaran at the position of the hydraulic cylinder. A pile hole is provided inside the oil cylinder base. The pile for lifting the catamaran is installed in the pile hole. The hydraulic cylinder is installed in the pile for lifting the catamaran.

[0010] For the low-water-level catamaran power generation ship of the present invention, when the water level exceeds the utilization water level of the power generation ship, the power generation ship can be lifted to let the excess water flow under the ship; when the water level is low, water is injected into the ship, and the power generation ship can generate electricity normally whether the water level rises or falls when it reaches the river bottom.

[0011] In order to prevent the power generation ship from being destroyed by ice floes in spring, the hull is equipped with four lifting bolt holes. Bolt piles can be lowered to the bottom of the river at a depth of about 10 meters through the bolt holes and fixed. When the ice floes are running in the spring, the four 500-ton hydraulic cylinders on the ship are used to support the four bolt piles fixed in the river to lift the ship to a height of 2-3 meters above the water surface to allow the ice floes to flow away from under the ship. When the ice floes are gone, the ship is lowered to the power generation water level.

[0012] To prevent debris from the river from blocking the turbine blades, a horizontal turbine is used. Generally, debris can flow through the center. To prevent larger debris from getting stuck in the main impeller, a fence is installed 12 meters from the front of the power plant. The deflector is equipped with multiple anti-stuck probes. If debris hits the probe along the deflector, an alarm sounds. The control cylinder on the deflector increases the distance between the deflector and the impeller. After the debris passes, the deflector control cylinder automatically returns to its original position.

[0013] The Songhua River is known for its strong winds, high waves, and high humidity. If the generator and turbine were connected together, firstly, it would be bulky and inconvenient to install and maintain. The power generation vessel of this invention is designed to facilitate both installation and maintenance of the generator. Secondly, it facilitates network transmission of power. Thirdly, it extends the service life of the generator. By separating the generator from the catamaran power generation vessel and installing it in a powerhouse onshore, the turbine drives a hydraulic pump to deliver hydraulic oil to shore via a pipeline. A hydraulic motor connected to the generator then drives the generator to generate electricity, creating a safe and convenient solution. Fourth, the turbine is easy to install and maintain. The turbine wheel, bearing seat assembly and hydraulic oil pump are installed as one. Because it is a horizontal axis transmission, a high-pressure oil pump is installed on each side of the shaft. The high-pressure oil pump body is fixed on the bearing seat. The box is a 2mX2m square box. Each catamaran is equipped with two grooves with a width of 2mX2m at the front and rear, which can just fit the bearing seat assembly box. When installing the turbine, first install the bearing seat assembly on the turbine wheel shaft. When the turbine and the hull are assembled, use a crane to lift the bearing seats on both sides into the groove of the catamaran. The installation is completed. In order to prevent the bearing seat assembly from being lifted up along the groove of the ship when the turbine is working, a bearing seat pressure cover is installed on the groove. There is a 5 mm gap between the pressure cover and the bearing seat if it is not tightened. At the bearing seat assembly box, a 2 cm strong rubber plate is glued on all four sides. The turbine assembly is not fastened on the catamaran but floats in the groove, which plays a centripetal role. BRIEF DESCRIPTION OF THE DRAWINGS
