DETAILED DESCRIPTION

[0039] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model. The experimental methods in the following embodiments are conventional methods, and the materials, reagents, etc. used in the following embodiments are commercially available unless otherwise specified.

[0040] As Figures 1-6 In the embodiment, the shell 1, the cylindrical block 5, the pipeline 7 and the power generation mechanism 8 are included;

[0041] The cylindrical block 5 is rotationally arranged inside the cylindrical hollow shell 1, and the axis of the cylindrical block 5 coincides with the axis of the shell 1, and the cylindrical block 5 rotates axially with its own axis as the axis;

[0042] The cylindrical block 5 is provided with the first channel 2 and the second channel 3 which penetrate the cylindrical block 5 along the direction of its own axis;

[0043] It should be noted that the first channel 2 and the second channel 3 have the same hole diameter, and the first channel 2 and the second channel 3 are arranged at an interval of 180°, and the distance between the axis of the first channel 2 and the axis of the second channel 3 and the axis of the shell 1 is equal;

[0044] Specifically, the first channel 2 and the second channel 3 can switch positions with each other due to the rotation of the cylindrical block 5, thereby completing the corresponding work;

[0045] The first channel 2 is provided with a mounting groove 50, the second channel 3 is provided with a flow channel 51, and the power generation mechanism 8 is mounted inside the mounting groove 50;

[0046] The pipeline 7 is arranged on the opposite sides of the shell 1, and the water inlet 10 and the water outlet 11 are respectively arranged at the opposite positions;

[0047] Specifically, when in the first working state, the axis of the pipe 7 and the axis of the first channel 2 coincide, the water flow flows into the first channel 2 through the pipe 7, and because the power generation mechanism 8 is arranged inside, the power generation mechanism rotates under the action of the water flow while the water flow moves downstream, generating electric current; when in the second working state, the axis of the pipe 7 and the axis of the second channel 3 coincide, and at this time, because there is no obstruction of the power generation mechanism 8, the water flow directly flows to the downstream through the flow channel 51 and finally flows into the external water tank, preventing the residents from lacking water during the peak period of water use.

[0048] In the embodiment, the wire part 4 and the moving electrode 6 are further included.

[0049] The wire part 4 is arranged outside the shell 1, and the wire part 4 extends to the inside of the shell 1.

[0050] The moving electrode 6 is arranged on the side wall of the cylindrical block 5 and corresponds to the position of the first channel 2.

[0051] Specifically, when in the first working state, the moving electrode 6 is in contact with the extension of the wire part 4, and the moving electrode 6 is electrically connected with the power generation mechanism 8, so that the electric current generated by the power generation mechanism 8 is transmitted to the wire part 4 through the moving electrode 6, and the wire part 4 finally supplies the electric current to the booster pump for power supply; when in the second working state, because the cylindrical block 5 rotates, the positions of the first channel 2 and the second channel 3 are exchanged, so that the moving electrode 6 changes the position at the same time, and the moving electrode 6 is disconnected with the wire part 4.

[0052] In the embodiment, the power generation mechanism 8 includes:

[0053] The power generation mechanism shell 81 is in contact with the inner wall of the mounting groove 50.

[0054] The coil winding 85 is fixed on the inner wall of the power generation mechanism shell 81 and is electrically connected with the wire part 4 through the moving electrode 6.

[0055] The impeller 80 is rotationally arranged in the inner cavity of the power generation mechanism shell 81, and the rotation axis of the impeller 80 coincides with the axis of the first channel 2.

[0056] The magnet 84 is fixed on the impeller 80.

[0057] Specifically, when in the first working state, the impeller 80 rotates together with the magnet 84, at this time, the magnet 84 and the coil winding 85 produce relative motion, the change of the magnetic field makes the coil generate electric current, and the electric current is transmitted to the wire part 4 through the moving electrode 6.

[0058] It should be noted that the front and rear sides of the impeller 80 are respectively provided with support heads 82, the support heads 82 are fixed to the inner side of the power generation mechanism shell 81 through three connecting rods 83, and the support heads 82 and the impeller 80 are connected through bearings;

[0059] Specifically, the support head 82 is connected with the impeller 80 through a bearing, which on the one hand ensures the stable rotation of the impeller 80 under the action of the water flow. Because the water flow is usually changing, the support head 82 helps to maintain the stability of the impeller 80, preventing the position of the impeller 80 from being deviated due to the impact of excessive water flow; on the other hand, because the impeller 80 in the water flow power generation system usually rotates at high speed under the action of a large water flow. The support head 82 and the bearing can reduce the friction between the impeller and the fixed part, reduce the rotation resistance, ensure the smooth rotation of the impeller, and improve the efficiency.

[0060] In this embodiment, a first annular groove and a second annular groove are arranged on the inner side of the shell 1 along the circumference of the water inlet 10 and the water outlet 11 respectively, and a first sealing ring 12 and a second sealing ring 13 are arranged in the first annular groove and the second annular groove respectively;

[0061] Specifically, when in the first working state, the first sealing ring 12 and the second sealing ring 13 are respectively attached to the two ends of the power generation mechanism shell 81, preventing the water flow from leaking outward through the gap between the power generation mechanism shell 81 and the shell 1; when in the second working state, the first sealing ring 12 and the second sealing ring 13 are clamped between the flow channel 51 and the shell 1, preventing outward leakage.

[0062] In this embodiment, the opposite sides of the shell 1 are also provided with an access hole 14;

[0063] It should be noted that when in the first working state, the central axis of the access hole 14 and the axis of the second channel 3 coincide;

[0064] When in the second working state, the central axis of the access hole 14 and the axis of the first channel 2 coincide;

[0065] Specifically, when in the second working state, because the positions of the access hole 14 and the power generation mechanism 8 are relative at this time, the power generation mechanism 8 is taken out through the opening of the access hole 14, so as to be maintained or replaced, and at the same time, the water use of residents is not affected.

[0066] In this embodiment, a rotating mechanism is arranged outside the shell 1, and the rotating mechanism drives the cylindrical block 5 through an output shaft;

[0067] It should be noted that the rotating mechanism is a servo motor, which is specifically installed at the center of the outer side of the shell 1, directly drives the cylindrical block 5 through an output shaft, or drives the rotator to rotate through a speed reducer, so as to improve the driving force of the servo motor;

[0068] Specifically, because the servo motor has high precision, the cylindrical block 5 can be accurately rotated by 180 degrees each time, thereby ensuring that the cylindrical block can be switched to different working states. Since the servo motor is a prior art, it will not be described here.

[0069] Working principle:

[0070] In the first working state, the axis of the pipeline 7 coincides with the axis of the first channel 2, and the water flow flows into the first channel 2 through the pipeline 7. At this time, because the water flow passes through the power generation mechanism 8, the impeller 80 will drive the magnet 84 to rotate, and the relative motion between the magnet 84 and the coil winding 85 generates an electric current. Because the position of the moving electrode 6 corresponds to the position of the wire part 4 to form a passage, the electric current is directly sent to the booster pump from the wire part 4 to supply power to the booster pump. Finally, the water flow flows into the external water tank through the water outlet 11;

[0071] In the second working state, the axis of the pipeline 7 coincides with the axis of the second channel 3. At this time, because there is no obstruction of the power generation mechanism 8, the water flow directly flows to the downstream through the flow channel 51, and finally flows to the external water tank, thereby preventing the residents from lacking water during the peak period of water use.

[0072] In the second working state, because the positions of the maintenance opening 14 and the power generation mechanism 8 are opposite, the power generation mechanism 8 is taken out by opening the maintenance opening 14, thereby being repaired or replaced.

[0073] The above shows and describes the basic principle, main features and advantages of the utility model. It should be understood by those skilled in the art that the utility model is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only preferred examples of the utility model and do not limit the utility model. Without departing from the spirit and scope of the utility model, the utility model can also have various changes and improvements, and these changes and improvements all fall within the scope of the utility model. The scope of protection of the utility model is defined by the appended claims and their equivalents.
