For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0035] Example 1

[0036] Combined with Figure 1The present embodiment provides an algae removal device, comprising a floatable shell 1, wherein a water flow channel 2 penetrating the shell 1 is provided in the middle of the shell 1; propellers 3 and algae removal filters 4 are provided at both ends of the water flow channel 2, wherein the propeller 3 is used to push the water flow toward the algae removal filters 4; a first one-way valve plate 19 is provided between the propeller 3 and the algae removal filters 4; a return flow channel 20 is provided at the lower end of the shell 1, wherein the outlet of the return flow channel 20 is located between the propeller 3 and the first one-way valve plate 19; and the return flow channel 20 is adapted to be equipped with a second one-way valve plate 21 connected to the water flow channel 2.

[0037] It is understandable that the shell 1 is a device that can float on water and can be made of lightweight materials such as foam, plastic, etc., or the hollow shell 1 can be made of denser materials such as stainless steel, aluminum alloy, etc.

[0038] The shape of the housing 1 may be a special shape, such as a panda shape, a fish shape or other bionic shape, or may be a square, a column or a sphere.

[0039] Among them, in order to prevent large-sized debris water from entering the water flow channel 2 and damaging the propeller 3, a debris filter 9 is provided at one end of the water flow channel 2 away from the algae removal filter 4. The algae removal filter 4 and the debris filter 9 can both regularly remove the debris thereon to ensure the normal operation of the filter.

[0040] In order to facilitate the installation and rotation of the first one-way valve plate 19 and the second one-way valve plate 21, the water flow channel 2 and the return flow channel 20 are usually square flow channels.

[0041] When this embodiment is in use, water is introduced into the water flow channel 2 through the propeller 3 and pushed toward the algae removal filter 4, so that the water flow pushes open the first one-way valve plate 19, and then sprays out of the water flow channel 2 after passing through the algae removal filter 4, so as to filter out algae in the water flow through the algae removal filter 4, thereby achieving the purpose of algae removal.

[0042] At the same time, water flows out from the water flow channel 2, which can drive the housing 1 to move in the direction opposite to the water spraying direction, so that the housing 1 automatically moves in the water body. In addition, the propeller 3 drives the water body to flow and the housing 1 to move, which has a certain inhibitory effect on the mass reproduction of algae, thereby slowing down the occurrence of algae blooms.

[0043] Among them, with the accumulation of algae in the water flow channel 2, the flow capacity of the water flow channel 2 decreases and the moving speed of the shell 1 also decreases accordingly; when it is necessary to return, the propeller 3 can be controlled to reverse, and at this time, the algae in the water flow channel 2 are stored in the water flow channel 2 under the action of the first one-way valve plate 19 and the algae removal filter 4, and the water in the water body pushes the second one-way valve plate 21 through the return flow channel 20 to enter the water flow channel 2, and flows in the direction away from the algae removal filter 4, thereby driving the shell 1 to return.

[0044] In summary, the present invention can automatically remove floating algae on the surface of the water body. Compared with the method of manual salvage by ship, it does not require human intervention, there is no movement of the ship, and the noise is small. It only needs to remove the algae filtered in the water flow channel 2 to avoid affecting the water quality and the organisms near the water area during algae removal. It has the characteristics of saving time and effort.

[0045] Example 2

[0046] This embodiment provides an algae removal device. Based on the structure and principle described in Embodiment 1, the propeller 3 is an electric propeller 3 , and the housing 1 is provided with a battery 5 electrically connected to the propeller 3 .

[0047] It is understandable that the electric propeller 3 is powered by the battery 5, and no cables are needed, so that the housing 1 can move freely. In contrast, the fuel function method has low noise, simple structure, and can avoid pollution caused by fuel leakage.

[0048] In addition, in order to improve the endurance of the algae removal device and reduce the consumption of electric energy, a solar panel is provided on the top of the shell 1, and the solar panel is rechargeably connected to the battery 5 to convert solar energy into electric energy to charge the battery 5 through the solar panel.

[0049] Usually, to ensure that the solar panel has sufficient light-collecting capacity, the solar panel is installed on the top of the shell 1 ; and to ensure the stability of the algae removal device, a heavy battery 5 is usually arranged inside the lower end of the shell 1 .

[0050] Furthermore, in order to facilitate wireless charging of the algae removal device, the present embodiment further includes an induction charging coil 6, so as to facilitate fast, cable-free charging of the algae removal battery 5, ensuring safety during charging. In order for the induction charging coil 6 to receive electrical energy normally, the induction charging coil 6 is disposed at the upper end of the housing 1.

[0051] Example 3

[0052] This embodiment provides an algae removal device, based on the structure and principle described in Example 2, the algae removal filter 4 is connected to the shell 1 through the mounting frame 7, and the upper end of the mounting frame 7 is hinged to the shell 1; it also includes a flipping drive mechanism, and the flipping drive mechanism is used to drive the mounting frame 7 to flip upward.

[0053] Specifically, when it is necessary to remove the algae in the water flow channel 2, the installation frame 7 is at least partially submerged in water, and the installation frame 7 is driven to flip upward by the flipping drive mechanism to drive the algae removal filter 4 to flip upward. In the process of the algae removal filter 4 flipping upward, the algae removal filter 4 can be backwashed through the relative movement of the algae removal filter 4 and the water.

[0054] After the angle between the algae removal filter 4 and the length direction of the water flow channel 2 is greater than or equal to 90 degrees, the propeller 3 rotates to spray water from the water flow channel 2, thereby spraying out all the algae filtered in the water flow channel 2 to automatically remove the collected algae. It is understood that when unloading the algae in the algae removal device, it is usually carried out at a designated berth so as not to cause the algae to leak out.

[0055] The flipping drive mechanism may be a flipping shaft driven by a motor, a telescopic three-link mechanism, etc. In this embodiment, the flipping drive mechanism includes a linear drive 8, one end of which is hinged to the housing 1, and the other end of which is hinged to the mounting frame 7. The mounting frame 7 is driven to flip upward by the contraction of the linear drive 8. The linear drive 8 is an electric push rod, which can simplify the structure of the algae removal device.

[0056] Example 4

[0057] This embodiment provides an algae removal device, based on the structure and principle described in any one of Embodiments 1-3, a heavy metal biosorption membrane 10 is provided in the water flow channel 2 to adsorb heavy metals in the water flow while removing algae.

[0058] Example 5

[0059] This embodiment provides an algae removal device. Based on the structure and principle described in Example 3, an electric steering rudder 11 is provided on the outside of the shell 1, and the electric steering rudder 11 and the algae removal filter 4 are located on the same side of the shell 1; it also includes a controller 12, an obstacle detection module 13, a positioning module 14 and a liquid level meter 15. The obstacle detection module 13 is used to detect obstacles in front of the shell 1 in the direction of travel, and the liquid level meter 15 is used to monitor the depth of the shell 1 sinking into the water body; the obstacle detection module 13, the positioning module 14, the liquid level meter 15 and the electric steering rudder 11 are all electrically connected to the controller 12.

[0060] It should be noted that the electric steering rudder 11 is powered by the battery 5 and operates under the control command output by the controller 12 to control the travel direction of the shell 1; the obstacle detection module 13 detects obstacles in the travel direction, which can be an ultrasonic detection module, an infrared detection module, etc.; the positioning module 14, usually a GPS positioning module 14, provides real-time feedback on the position of the algae removal device, so as to control the travel and return of the route set by the installation of the algae removal device.

[0061] During the algae removal process, as the algae accumulate in the water passage 2, the weight of the algae removal device increases, and the housing 1 gradually sinks into the water body. Therefore, a liquid level gauge 15 can be provided on the housing 1, and the amount of algae accumulation in the housing 1 can be determined by the reading of the liquid level gauge 15, so that the housing 1 can be controlled to return when the amount of algae accumulation reaches the maximum value. The liquid level gauge 15 is triggered only at a set value. In this embodiment, the liquid level gauge 15 can be a Hall type liquid level gauge 15 or a mechanical liquid level gauge 15.

[0062] In order to facilitate setting the driving route for the algae removal device, the present embodiment also includes an information input module 16 and an information storage module 17 electrically connected to the controller 12. The information input module 16 is used to enter navigation information, and the information storage module 17 is used to store navigation information, so as to control the housing 1 to travel according to the entered navigation information.

[0063] In this embodiment, in order to ensure that the algae removal device has sufficient passing capacity, the shell 1 is spherical. At the same time, the spherical shell 1 has a small volume at both ends and a large volume in the middle, so that after a certain amount of algae is collected in the water flow channel 2, the shell 1 sinks quickly, so that the propeller 3 quickly submerges in the water, thereby improving the collection efficiency of the algae.

[0064] In order to ensure that the algae removal device has enough power for returning, it is usually forced to return when the power of the battery 5 is less than 15%.

[0065] Example 6

[0066] This embodiment provides an algae removal method, based on the algae removal device described in Example 5, comprising the following steps:

[0067] S1. Place the algae removal device in the water to be algae removed, so that the propeller 3 and the electric steering rudder 11 are at least partially inserted into the water, and generally ensure that the depth of the propeller 3 inserted into the water is greater than 1 cm;

[0068] S2, controlling the propeller 3 and the electric steering rudder 11 to move the housing 1 along a preset route;

[0069] S3, real-time monitoring of the battery 5 power and the level gauge 15 reading, and respectively comparing the battery 5 power with the return power and the level gauge 15 reading with the return liquid level;

[0070] When the battery 5 has a charge greater than or equal to the return charge (15% of the full charge), or the level gauge 15 has a reading greater than or equal to the return level, the housing 1 is driven to return;

[0071] S4, after the housing 1 returns to the berthing port, the mounting frame 7 is driven to flip upward, and the propeller 3 drives the water flow to spray out the algae filtered in the water flow channel 2.

[0072] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. According to the technical essence of the present invention, within the spirit and principles of the present invention, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the present invention.
