[0002] The drainage device in the cabin of a human-powered sailboat is usually designed to remove the accumulated water inside the cabin to ensure the dryness and safety of the cabin.

[0003] In the prior art, water in the cabin of a human-powered sailboat is often sucked out of the boat by a water pump. The water pump requires power to drive it. Then the water pump and the battery that provides power to it will increase the mass of the boat, thereby affecting the sailing speed of the human-powered sailboat. Therefore, a drainage device in the cabin of a human-powered sailboat is proposed to solve the above problem. Utility Model Content

[0004] (1) Technical problems solved

[0005] In response to the shortcomings of the existing technology, the utility model provides a drainage device for the cabin of a human-powered sailboat. The drainage device has the advantages of being lighter than a water pump and having less impact on the sailing speed of the human-powered sailboat. It solves the problem in the existing technology that water in the cabin of a human-powered sailboat is often sucked out of the boat by a water pump, and the water pump requires power to drive it. Then the water pump and the battery that provides power to it will increase the mass of the boat, thereby affecting the sailing speed of the human-powered sailboat.

[0006] (2) Technical solution

[0007] The technical solution of the utility model for solving the above-mentioned technical problems is as follows: A drainage device in a human-powered sailboat cabin, comprising a hull, a bent pipe extending to the stern is provided inside the bottom wall of the hull, the right end of the bent pipe is connected to the lowest point of the bottom wall of the hull, the bottom wall of the hull is fixedly connected to a water collecting cover connected to the right end of the bent pipe, a cross support plate is fixedly connected to the inside of the water collecting cover, an adjusting bolt is rotatably connected to the center of the top of the cross support plate, the outer side of the adjusting bolt is provided with a lifting valve assembly threadedly connected to the cross support plate and slidingly connected to the cross support plate and adapted to the water collecting cover, and the left end of the bent pipe is provided with a water absorption assembly connected thereto.

[0008] The beneficial effect of the present invention is that when the human-powered sailboat needs to discharge the water flowing into the hull during navigation, the adjusting bolt is rotated by a wrench, and the force generated by the rotation of the thread drives the lifting valve assembly to move upward, thereby connecting the inside of the hull with the bent pipe. During navigation, the human-powered sailboat flows through the water absorption assembly, so that a low pressure is formed in the water absorption assembly, and then the water inside the hull is sucked out through the bent pipe and discharged from the left side of the water absorption assembly in line with the water flow passing through the water absorption assembly. The drainage device in the cabin of the human-powered sailboat has the advantages of being lighter than a water pump and having less influence on the navigation speed of the human-powered sailboat.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the lifting valve assembly includes a lifting cover body, a sealing ring, an annular filter screen, a support ring and a sliding rod. The outer side of the adjusting bolt is threadedly connected to the lifting cover body that is adapted to the water collecting cover. The outer side of the lifting cover body is sleeved with a sealing ring that fits tightly with the inner wall of the water collecting cover. The bottom edge of the lifting cover body is fixedly connected to an annular filter screen. The bottom of the annular filter screen is fixedly connected to a support ring that is adapted to the water collecting cover. The bottom of the lifting cover body is fixedly connected to a sliding rod that is symmetrically distributed on the left and right and is slidably connected to the cross support plate.

[0011] The beneficial effect of adopting the above-mentioned further scheme is that by turning the adjusting bolt with a wrench, the force generated by the rotation of the thread drives the lifting cover body to move upward in the water collecting cover, and at the same time the slide rod and the cross support plate slide until the lifting cover body drives the sealing ring to separate from the water collecting cover, so that the interior of the hull can be connected with the bending pipe. The adjusting bolt is continued to be turned to adjust the lifting height of the lifting cover body, that is, to adjust the size of the drain outlet. The annular filter net at the bottom of the lifting cover body can block foreign matter in the hull, preventing foreign matter from entering the water collecting cover and then clogging the bending pipe.

[0012] Furthermore, the top edge of the water collecting cover is flush with the bottom wall of the hull.

[0013] The beneficial effect of adopting the above further solution is that it facilitates the discharge of water flowing into the hull.

[0014] Furthermore, the water suction assembly includes a water suction pipe, an open pipe and a barrier net. The left end of the bent pipe is fixedly connected to a water suction pipe parallel to the direction of travel of the hull and connected to the bent pipe. The right end of the water suction pipe is fixedly connected to an open pipe connected thereto. The opening of the open pipe faces the direction of travel of the hull, and the right end of the open pipe is fixedly connected to the barrier net.

[0015] The beneficial effect of adopting the above-mentioned further scheme is that when the human-powered sailboat is sailing, water flows into the right side of the open pipe and flows through the suction pipe and is discharged from the left side thereof. During this process, the cross-sectional diameter of the open pipe gradually decreases from right to left, thereby hindering the incoming water. When the water flows into the suction pipe, the flow rate is higher than that of the incoming flow, and the pressure is lower than that of the incoming flow, so the water flowing into the hull can be sucked out through the bent pipe.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] In the embodiment, Figure 1-4 Provided is a drainage device for a man-powered sailboat cabin. The utility model comprises a hull 1, wherein a bent pipe 2 extending to the stern is provided inside the bottom wall of the hull 1, and the right end of the bent pipe 2 is communicated with the lowest point of the bottom wall of the hull 1. A water collecting cover 3 communicating with the right end of the bent pipe 2 is fixedly connected to the bottom wall of the hull 1, and a cross support plate 4 is fixedly connected to the inside of the water collecting cover 3. An adjusting bolt 5 is rotatably connected to the center of the top of the cross support plate 4. A lifting valve assembly 6 threadedly connected to the adjusting bolt 5 and slidably connected to the cross support plate 4 and adapted to the water collecting cover 3 is provided on the outer side of the adjusting bolt 5. The left end of the bent pipe 2 is provided with a water absorption assembly 7 communicated with the cross support plate 4.

[0023] The lifting valve assembly 6 includes a lifting cover body 601, a sealing ring 602, an annular filter screen 603, a support ring 604 and a sliding rod 605. The outer side of the adjusting bolt 5 is threadedly connected to the lifting cover body 601 adapted to the water collecting cover 3. The outer side of the lifting cover body 601 is sleeved with a sealing ring 602 that fits tightly with the inner wall of the water collecting cover 3. The bottom edge of the lifting cover body 601 is fixedly connected to the annular filter screen 603. The bottom of the annular filter screen 603 is fixedly connected to the support ring 604 adapted to the water collecting cover 3. The bottom of the lifting cover body 601 is fixedly connected to the sliding rod 605 that is symmetrically distributed on the left and right and is slidably connected to the cross support plate 4;

[0024] By turning the adjusting bolt 5 with a wrench, the force generated by the rotation of the thread drives the lifting cover 601 to move upward in the water collecting cover 3. At the same time, the sliding rod 605 and the cross support plate 4 slide until the lifting cover 601 drives the sealing ring 602 to separate from the water collecting cover 3, so that the interior of the hull 1 is connected with the bending pipe 2. The adjusting bolt 5 is further turned to adjust the lifting height of the lifting cover 601, that is, to adjust the size of the drain outlet. The annular belt-shaped filter screen 603 at the bottom of the lifting cover 601 can block foreign matter in the hull 1, preventing foreign matter from entering the water collecting cover 3 and then clogging the bending pipe 2.

[0025] The top edge of the water collecting cover 3 is flush with the bottom wall of the hull 1;

[0026] Facilitates the discharge of water flowing into the hull 1;

[0027] The water absorption assembly 7 includes a water absorption pipe 701, an open pipe 702, and a barrier net 703. The left end of the bent pipe 2 is fixedly connected to the water absorption pipe 701, which is parallel to the travel direction of the hull 1 and communicates with the bent pipe 2. The right end of the water absorption pipe 701 is fixedly connected to the open pipe 702, which is communicated with the open pipe 702. The open end of the open pipe 702 faces the travel direction of the hull 1, and the right end of the open pipe 702 is fixedly connected to the barrier net 703.

[0028] When the human-powered sailboat is sailing, water flows into the open pipe 702 from the right side, flows through the suction pipe 701 and is discharged from the left side. During this process, the cross-sectional diameter of the open pipe 702 gradually decreases from right to left, thereby hindering the inflow of water. When the water flows into the suction pipe 701, the flow rate is higher than that of the incoming flow, and the pressure is lower than that of the incoming flow, so the water flowing into the hull 1 can be sucked out through the bent pipe 2.

[0029] Working principle:

[0030] Step 1: When the human-powered sailboat needs to drain the water flowing into the hull 1 during navigation, the adjusting bolt 5 is turned by a wrench. The force generated by the rotation of the thread drives the lifting cover 601 to move upward in the water collecting cover 3. At the same time, the sliding rod 605 and the cross support plate 4 slide until the lifting cover 601 drives the sealing ring 602 to separate from the water collecting cover 3, so that the interior of the hull 1 is connected to the bending pipe 2.

[0031] Step 2: Continue to turn the adjusting bolt 5 to adjust the height of the lifting cover 601, that is, adjust the size of the drainage port. The annular filter 603 at the bottom of the lifting cover 601 can block foreign matter in the hull 1, preventing foreign matter from entering the water collecting cover 3 and then clogging the bent pipe 2;

[0032] Step 3: In the above process, water flows into the open pipe 702 from the right side, flows through the suction pipe 701 and is discharged from the left side. In this process, the cross-sectional diameter of the open pipe 702 gradually decreases from right to left, which then has an obstructive effect on the incoming water. When the water flows into the suction pipe 701, the flow rate is higher than the incoming flow, and the pressure is lower than the incoming flow, so the water flowing into the hull 1 can be sucked out through the bent pipe 2.
