Abstract

The invention relates to the technical field of ships, in particular to a ship, which comprises a ship body, an impeller and a culvert gate; the bottom of the ship body is provided with a duct penetrating through the ship body. The water flow can flow into the duct from the inlet of the duct and can flow out of the duct from the outlet of the duct.

The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.

As described in the background art, in order to enable power generation by water flow, a duct or a water flow passage penetrating the hull is generally provided at the bottom of the hull. An impeller for generating electricity is arranged in the duct. When the water flow flows through the duct or the water flow channel, the impeller for power generation can rotate by means of the power of the water flow, and then the generator is driven to generate power. However, when power generation is performed by means of a conventional ship, the power generation efficiency is still low, and the requirements cannot be met.

To improve the above problems, referring to fig. 1, 2, 3, 4, 5, 6, 7, 8 and 9, there is provided a ship including a hull 110, an impeller 120 and a duct door 130. A duct 111 penetrating the hull 110 is provided at the bottom of the hull 110. The inlet of duct 111 is located at the vessel head of hull 110 and the outlet is located at the vessel tail of hull 110. The inlet size of the duct 111 is larger than the outlet size of the duct 111. The water flow can flow into the duct 111 from the inlet of the duct 111 and can flow out of the duct 111 from the outlet of the duct 111. The impeller 120 is rotatably arranged at the outlet of the duct 111 and is adapted to be connected to the input shaft of a generator. The impeller 120 is rotated in one direction by the water flow from the outlet of the duct 111, and the input shaft of the generator is driven to rotate, so that the generator generates electricity. The bypass door 130 is disposed at the inlet of the bypass 111, and is used for adjusting the opening degree of the inlet of the bypass 111 so that the opening degree of the inlet of the bypass 111 is larger than the opening degree of the outlet.

The degree of opening refers to the size of the cross section of the inlet of the duct 111/the outlet of the duct 111. It is assumed that both ends of the river channel extend in the east-west direction, respectively. When hull 110 is automatically driven down a river channel at a speed of 20m/s in the east-west direction, water flows from the west to the east at a speed of 2m/s, and the water flows into the inlet of duct 111 at a relative speed of 22 m/s. Since the relative flow velocity is much lower than the sonic velocity, and since the cross-sectional dimension of the inlet of the duct 111 is greater than that of the outlet of the duct 111, the water flow will flow out of the outlet of the duct 111 at a relative flow velocity greater than 22m/s, and the flow velocity equivalent to the water flow is improved to a certain extent in the duct 111, thereby improving the rotational speed of the impeller 120 and further improving the power generation efficiency. According to the actual need, the opening degree of the inlet of the duct 111 is adjusted by means of the duct gate 130 such that the ratio of the opening degree of the inlet of the duct 111 to the size of the cross section of the outlet of the duct 111 is (2-6): 1, and further adjusting the power generation efficiency. Compared with the mode of adjusting the power generation efficiency by increasing the number of impellers and reducing the number of impellers, the power generation efficiency adjusting precision is higher.

Preferably, as shown in fig. 4 or 8, the duct 111 includes a first duct section 1111, a second duct section 1112, a third duct section 1113, and a fourth duct section 1114, which are sequentially communicated. The end of the first duct section 1111 remote from the second duct section 1112 is the inlet of the duct 111. The end of the fourth bypass segment 1114 remote from the third bypass segment 1113 is the outlet of the bypass 111. The bypass gate 130 is mounted within the first bypass segment 1111. Impeller 120 is mounted within fourth bypass segment 1114. The size of the cross section of the second duct section 1112 is smaller than or equal to the size of the cross section of the first duct section 1111, the size of the cross section of the third duct section 1113 is smaller than or equal to the size of the cross section of the second duct section 1112, and the size of the cross section of the fourth duct section 1114 is smaller than or equal to the size of the cross section of the third duct section 1113, so that multistage acceleration of water flow entering the duct 111 is realized, and the power generation efficiency is ensured.

In some of these embodiments, referring to fig. 1, 2, 3 and 4, the culvert gate 130 is comprised of a bottom plate 131, two first side plates 132, a winding drum 133, a pull rope 134, a first rotary drive 135, a drive gear 136 and a driven gear 137. One side of the bottom plate 131 is rotatably coupled to the bottom of the hull 110 through a rotation shaft 1383, and the other side can be moved up and down. Two first side plates 132 are respectively fixed to opposite ends of the bottom plate 131. The mutually facing sides of the two first side plates 132 are respectively attached to the inner walls of the opposite sides of the bottom of the hull 110, i.e. the mutually separated sides of the two first side plates 132 are respectively attached to the inner walls of the opposite sides of the first duct section 1111. The winding drum 133 is rotatably installed inside the upper portion of the hull 110 with its axis perpendicular to the side plate. One end of the traction rope 134 is wound on the winding drum, and the other end is fixedly connected with the middle part of the bottom plate 131. First rotary actuator 135 is mounted to the outside or inside of the upper portion of hull 110. The driving gear 136 is sleeved on the output shaft of the first rotary driver 135. The side wall of the driven gear 137 is engaged with the side wall of the driving gear 136, and the middle part is sleeved at one end of the winding drum 133. The first rotary driver 135 drives the driving gear 136 to rotate, and then drives the driven gear 137 and the winding drum 133 to rotate, so that the traction rope 134 is gradually wound on the winding drum 133 or gradually released from the winding drum 133, and thus the bottom plate 131 and the side plates are driven to move up and down.

Preferably, each of the first side plates 132 is a fan-shaped plate structure.

Preferably, opposite ends of the winding drum 133 are rotatably coupled to the hull 110 by bearings.

Preferably, the pull cord 134 is a cable.

Preferably, the first rotary drive 135 is a servo motor or stepper motor or the like.

Preferably, the driving gear 136 is smaller in size than the driven gear 137 to transmit more torque to the winding drum 133.

It is noted that the vessel further comprises a blocking grid 140 and a linear drive 150 in order to prevent the flow of floats in the water into the duct 111. The blocking grille 140 is provided at the inlet of the duct 111 to be movable up and down. The linear driver 150 is mounted on the top of the hull 110, and the output shaft is fixedly connected to the top of the blocking grid 140 for driving the blocking grid 140 to move up and down. When the inlet of the duct 111 is in a closed state, the blocking grid 140 may be received in the hull 110. In the process that the blocking grating 140 is stored in the ship body 110, the bottom of the ship body 110 forces attachments on the blocking grating 140 to be separated from the blocking grating 140, manual cleaning is not needed, the difficulty of cleaning attachments is reduced, and the cleaning efficiency of attachments is improved.

Preferably, the linear actuator 150 is an electric push rod, an electric cylinder or an air cylinder. A mount for supporting the linear actuator 150 is fixed to the top of the hull 110.

In other embodiments, referring to fig. 5, 6, 7, 8, and 9, the bypass door 130 is comprised of two second side plates 138 and two second rotary drives 139. The two second side plates 138 are disposed obliquely, respectively, and one ends thereof cross each other. The middle parts of the two second side plates 138 are respectively rotatably connected with the opposite sides of the ship's head of the hull 110 through a rotating shaft 1383. The crossing ends of the two second side plates 138 are provided with blocking partitions 1381 which are staggered with each other. Opposite ends of the intersecting ends of the two second side plates 138 form respective baffles 1382. Two second rotary drivers 139 are respectively installed at opposite sides of the top of the bow of the ship of the hull 110. The output shafts of the two second rotary drivers 139 are fixedly connected to the top ends of the two rotary shafts 1383 in a one-to-one correspondence manner, and are used for driving the corresponding rotary shafts 1383 to rotate, so that the opposite ends of the intersecting ends of the two second side plates 138 are close to each other or far from each other.

The baffles 1382 formed at opposite ends of the intersecting ends of the two second side plates 138 serve as guide plates for the water flow, and can guide the water flow to the duct 111. The crossing ends of the two second side plates 138 are provided with blocking partitions 1381 which are staggered with each other. The blocking partitions 1381 on each side panel can function as a blocking grid. When the water flows into the duct 111, the floats in the water can be effectively prevented from entering the duct 111. The two second side plates 138 can not only adjust the opening degree of the inlet of the duct 111, but also intercept the sundries floating in the water, and the blocking grids are not required to be arranged independently, so that the use of parts is reduced, and the manufacturing cost is reduced. Moreover, when the opposite ends of the intersecting ends of the second side plates 138 are mutually far away, the blocking partitions 1381 on the two second side plates 138 can mutually remove attachments, so that the purpose of self-cleaning is achieved, manual cleaning is not needed, the difficulty of cleaning attachments is reduced, and the cleaning efficiency of attachments is improved.

Preferably, the second rotary drive 139 is a servo motor or a stepper motor.
