[0019] The present invention is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0020] like Figure 1 and Figure 2 As shown, the present invention provides a shallow water tidal power generation device with the function of measuring bottom scouring and silting, comprising an outer frame of the device, a cylindrical guide rail 5 with a coil and an above-water floating body.

[0021] The outer frame of the device includes an above-water frame structure 1 and a support structure 2. One end of the support structure 2 is distributed at the four corners of the above-water frame 1 and is connected to the above-water frame structure. The connection can be made by welding or other methods. The other end of the support structure 2 extends deep into the bottom of the water. The support structure 2 is four stainless steel columns, which are used to fix and support the entire device. The outer frame of the device is hollow as a whole and is used for installing equipment and wiring. The four stainless steel columns of the support structure 2 are distributed with a pressure sensor group 6. The cables of the pressure sensor group 6 are connected to the upper above-water frame structure 1 through the inside of the support structure 2, which is used to regularly obtain pressure signals at different depths and transmit them to the system processor 8.

[0022] In the embodiment of the present application, the floating body on the water includes a pancake-shaped floating body 3 and a cylindrical floating body 4. The floating body on the water is connected to a cylindrical guide rail 5 with a coil through two stainless steel structures. The floating body on the water is connected to the outer frame of the device by four iron chains with a certain degree of slack to prevent the floating body on the water from excessive movement. The pancake-shaped floating body 3 is parallel to the water surface, increasing the contact area of ​​the floating body with the water surface, which is used to improve the relative stability of the floating body; the cylindrical floating body 4 is perpendicular to the water surface, swinging up and down and left and right with the water flow, which is used to drive the upper coil to move and cut the magnetic flux lines.

[0023] In the embodiment of the present application, the cylindrical guide rail 5 with coil is wound by coil on the cylindrical guide rail and is perpendicular to the incoming flow direction. The cylindrical guide rail 5 with coil is connected to the floating body on the water through a stainless steel structure to form an overall common movement. Both ends of the coil are connected to the system processor 8 for power supply.

[0024] Preferably, the number of coil turns in the device, the fixing method and angle of the water frame, the size of the water float and the connection method with the cylindrical guide rail with the coil can be adjusted according to needs, which is only shown in the figure.

[0025] like Figure 2 As shown, in the embodiment of the present application, the device also includes a permanent magnet 7, which is installed on both sides of the above-water frame structure 1 to provide a stable magnetic field; the permanent magnet 7 is perpendicular to the main incoming flow direction to ensure that the coil is perpendicular to the magnetic flux lines. The system processor 8 is installed on the side of the above-water frame structure 1 that is different from the permanent magnet 7. The cable of the pressure sensor group 6 enters the above-water frame structure 1 through the support structure 2 and is connected to the system processor 8. The system processor 8 is coupled with the pressure data processing system, the terrain data visualization system and the data remote wireless transmission system. The device itself is self-powered. The pressure sensor group 6 transmits the pressure information to the system processor, processes the pressure data into visualized terrain data and transmits it wirelessly to the user end. The cables on both sides of the coil on the cylindrical guide rail 5 with the coil are connected to the power supply in the system processor, and the excess electricity is exported through an external cable to achieve the purpose of shallow water tidal energy power generation.

[0026] Preferably, the number and spacing of the pressure sensor groups distributed on the four stainless steel columns can be adjusted according to actual needs. In actual applications, some of the pressure sensors should be located underground and some should be located in water to identify terrain erosion and siltation. The stainless steel columns of the support structure are mainly used to support the entire device and serve as carriers of the pressure sensor group. If necessary, the number of stainless steel columns can be increased.

[0027] Preferably, the device is divided into two parts, above water and underwater. The above water floating body is located on the water surface and underwater as the force-bearing and moving body, and the movement of the above water floating body and the cylindrical guide rail as a whole is transmitted to the coil through the above water frame structure; The above-water floating body, which comprises a circular pancake-shaped floating body on the water surface and a cylindrical floating body perpendicular to the water surface, can effectively utilize the energy of water flow and vortex on the water surface and underwater.

[0028] The power generation bodies such as the permanent magnets and coils are located above the water, which can effectively avoid safety problems such as rust or leakage.

[0029] Preferably, the overall shape of the device imitates the thick columnar root system of mangroves, and a large number of staggered columnar roots can achieve good wave-breaking and flow-blocking effects.

[0030] The device can be used as a single unit, and multiple single units can be grouped in different arrangements according to needs to form a group of shallow water tidal power generation devices, thereby improving power generation efficiency while achieving coastal protection and monitoring coastal erosion and siltation on a large scale.

[0031] The present invention also provides an application of a shallow water tidal power generation device with bottom scouring and silting measurement, using the above-mentioned device, such as being arranged in a single or group form in front of a coast that needs to be protected, or in a single or group form behind existing marine structures such as bridge piers and wind turbines.

[0032] The application scenarios are as follows: Application scenario 1: Coastal scene When the shallow water tidal power generation device is arranged in a single or group form in front of the coast that needs to be protected, the waves generated near the shore will cause the floating body to move up and down, driving the coil to cut the magnetic flux lines to generate an induced electromotive force. The incoming flow perpendicular to the coastline direction will cause the cylindrical floating body to swing left and right when it encounters the cylindrical floating body, driving the coil to cut the magnetic flux lines to generate an induced electromotive force; after the water flows through the cylindrical floating body, a swinging wake is formed at the rear due to vortex shedding. If other shallow water tidal power generation devices are arranged at the rear, these devices can swing left and right better to generate electricity. In this process, the energy of waves and currents is consumed, which plays a role in protecting the coastline. At the same time, the bottom scouring and silting measurement system monitors the scouring and silting of the coastal zone.

[0033] Application scenario 2: Behind the marine structure At present, there are a large number of marine structures in the ocean, such as the piers of cross-sea bridges, the pile foundations of offshore wind turbines, etc. When the shallow water tidal power generation device is arranged behind such marine structures in a single or group form, the water flow forms a relatively stable Karman vortex street behind the marine structure. One or more shallow water tidal power generation device layout positions are selected according to the vortex street shape, so that the floating body of the device can swing to the maximum extent under the action of the vortex street, driving the coil to cut the magnetic flux lines to generate induced electromotive force and achieve maximum power generation efficiency. The bottom bed erosion and siltation measurement system monitors the erosion behind the bridge piers, which is conducive to the safety protection management of the bridge piers.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that several improvements and supplements may be made without departing from the principles of the present invention, and these improvements and supplements should also be regarded as the scope of protection of the present invention.
