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 background technology, a traditional device for generating electricity by means of water flow is provided with an interception mechanism at an opening at one end of an axial flow generator, and the interception mechanism is used for preventing sundries carried in the water flow from entering the axial flow generator. However, the interception effect of the interception mechanism of the traditional device for generating electricity by means of water flow is poor, and the actual requirement cannot be met.

In order to improve the above problems, referring to fig. 1, 2,3, 4,5 and 6, there is provided an apparatus 100 for generating electricity by means of water flow, comprising a scraper ring 110, an axial flow type electricity generating mechanism 120 and an intercepting mechanism 130. The scraper ring 110 is rotatably installed at the inner bottom surface of the hull 200. The middle part of the scraper ring 110 is hollow to form a first abdication hole for the axial flow type generating mechanism 120 to pass through. The scraping ring 110 is provided with a second abdication hole for the lower part of the interception mechanism 130 to pass through. The axial flow power generation mechanism 120 is disposed above the scraper ring 110 and can move up and down to protrude out of the hull 200 through the first relief hole or move into the hull 200 through the first relief hole. The interception mechanism 130 is also disposed above the scraper ring 110. The interception mechanism 130 includes a plurality of blocking bars 131. The axis of each blocking rod 131 is disposed vertically. The blocking bars 131 are disposed around at least one side of the axial flow power generation mechanism 120, and form a blocking grid on at least one side of the axial flow power generation mechanism 120. The blocking rods 131 can move up and down to pass through the second yielding Kong Tanchu to the outside of the hull 200 by a predetermined length or pass through the second yielding holes to the inside of the hull 200, respectively. Each blocking lever 131 is rotatable about the axis of the axial flow power generation mechanism 120. The axial spacing of each adjacent two of the blocking rods 131 is adjustable. The plurality of second relief holes are in one-to-one correspondence with the plurality of blocking rods 131. Each second abdicating hole is a oblong hole so as to meet the requirement of adjusting the axial distance between two adjacent blocking rods 131. The axial flow power generation mechanism 120 can rotate around its own axis along with the blocking lever 131.

It should be noted that the apparatus 100 for generating electricity by means of water flow is integrally installed inside the bottom of the hull 200. When the device 100 for generating electricity by means of water flow is in an idle state, both the axial flow type electricity generating mechanism 120 and the interception mechanism 130 are located above the scraper ring 110.

When the device 100 for generating electricity from water currents is in operation, there are several modes of operation:

In the first mode of operation, the axial flow power generation mechanism 120 is moved downward to protrude out of the hull 200 through the first relief hole, after which the axial flow power generation mechanism 120 is able to generate power by means of the water flow under the hull 200. The axial flow power generation mechanism 120 is rotatable about its own axis. The water-facing angle of the axial flow type power generation mechanism 120 can be adjusted according to the flow direction of the water flow, so that the maximum utilization rate of the water flow is realized, and the power generation efficiency is ensured.

In the second mode of operation, first, the plurality of blocking rods 131 are moved downward to pass through 10cm to 30cm outside the second yielding Kong Tanchu hull 200, respectively. In this way, before the axial flow power generation mechanism 120 is immersed in the water, protection is provided against entry of debris into the axial flow power generator 122. Thereafter, the axial flow power generation mechanism 120 is moved downward to protrude outside the hull 200 through the first relief hole. The axial flow power generation mechanism 120 is capable of generating power by means of water flow under the hull 200. In addition, the axial flow type power generation mechanism 120 can rotate around the axis of the axial flow type power generation mechanism, and the water facing angle of the axial flow type power generation mechanism 120 can be adjusted according to the flow direction of water flow, so that the maximum utilization rate of the water flow is realized, and the power generation efficiency is ensured. When the water flow has more sundries, each blocking rod 131 rotates around the axis of the axial flow generating mechanism 120 and drives the axial flow generating mechanism 120 to rotate, so that the blocking rods 131 of the blocking mechanism 130 are positioned at the water facing end of the axial flow generating mechanism 120, and sundries are prevented from entering the axial flow generating mechanism 120. Meanwhile, according to the size of sundries in the water flow, the axial distance between every two adjacent blocking rods 131 can be adjusted so as to meet diversified interception requirements. When the water flow has little or no sundries, each blocking rod 131 rotates around the axis of the axial flow generating mechanism 120 and drives the axial flow generating mechanism 120 to rotate, so that the blocking rods 131 of the blocking mechanism 130 are positioned at one end of the axial flow generating mechanism 120 where the water is carried, and by means of the impact of the water flow, a part of sundries attached to the blocking rods 131 fall off from the blocking rods 131. While the blocking rod 131 moves upward in the course of the device 100 for generating electricity by means of water flow from the second operation mode to the idle state, the scraping ring 110 forces another part of the foreign matters attached to the blocking rod 131 to be separated from the blocking rod 131 in the course of moving into the hull 200 through the second yielding hole. The two sundries removing modes are combined, the blocking rod 131 is cleaned conveniently, the cleaning effect is guaranteed, and the cleaning difficulty is reduced.

The plurality of sliders 1342 are fixedly connected to the top ends of the plurality of blocking bars 131 in one-to-one correspondence. Each slider 1342 is capable of moving up and down with the rotary ring 133, thereby moving each blocking lever 131 up and down. The first medium storage bag 1351 is capable of being deformed to a preset extent, and two opposite ends of the first medium storage bag are fixedly connected with the fixing block 1341 and one of the sliding blocks 1342 respectively. Each second medium storage bag 1352 is also capable of being deformed to a preset extent, and opposite ends of the second medium storage bag are fixedly connected with each two adjacent sliding blocks 1342 respectively, so that the distance between each two adjacent sliding blocks 1342 is adjustable, and the axial distance between each two adjacent blocking rods 131 is adjustable. It will be appreciated that each slide 1342 slides about the axis of the rotating ring 133 as the inter-axle distance of each adjacent two of the blocking rods 131 needs to be adjusted. When the positions of the plurality of blocking rods 131 need to be adjusted, the fixed block 1341 and the plurality of sliding blocks rotate along with the rotating ring 133.
