[0002] With the acceleration of industrialization and rising economic levels, pollution in natural water bodies, such as lakes, is becoming increasingly serious. Deteriorating water quality not only impacts the ecological environment but also poses numerous challenges to people's production and daily lives. Lake water often contains pollutants such as suspended solids, organic matter, nitrogen and phosphorus compounds, and heavy metals. If these pollutants are not effectively treated, they will cause long-term damage to lake ecosystems and even threaten human health. To address lake water pollution, a variety of water purification technologies have been researched and applied, primarily including physical precipitation, filtration, adsorption, and chemical coagulation and sedimentation. Water purification technology has evolved from traditional simple physical filtration to modern, highly complex membrane technologies, significantly improving the efficiency and quality of water treatment. However, neither traditional wisdom nor modern innovation has integrated multiple purification functions, including physical, chemical, and biological, into a single device. Furthermore, single water purification technologies are ineffective in removing dissolved pollutants and fine particles.

DETAILED DESCRIPTION

[0037] The following describes the embodiments of the present application through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present application from the content disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless they conflict.

[0038] The specific implementation of the present application is further described in detail below with reference to the accompanying drawings and examples.

[0039] Example 1:

[0040] The present application provides a multifunctional lake water purification device, such as Figures 1 to 3 As shown, the physical, chemical and biological multifunctional lake water purification device includes a main body 1, a first telescopic component 2, a grid 3, a second telescopic component 4, a solar panel 5, a mounting plate 6, a battery 12, a propeller 7 and a water purifier 8; the main body 1 has a symmetrical first end face 101 and a second end face 102, the second telescopic component 4 is installed on the first end face 101, and the first telescopic component 2, the propeller 7 and the water purifier 8 are installed on the second end face 102; the grid 3 is installed on the first telescopic component 2; the second telescopic component 4, the solar panel 5 and the mounting plate 6 are arranged in multiple and the same number, each second telescopic component 4 is equipped with a mounting plate 6, and the solar panel 5 is fixedly mounted on the mounting plate 6, and the multiple solar panels 5 are staggered in the vertical space to be stacked or unfolded under the action of the second telescopic component 4; the multiple solar panels 5 are all electrically connected to the battery 12, and the battery 12 is connected to the first telescopic component 2, the second telescopic component 4, the propeller 7 and the water purifier 8, for providing a source of electricity for the first telescopic component 2, the second telescopic component 4, the propeller 7 and the water purifier 8.

[0041] In this embodiment, a plurality of stackable or unfoldable solar panels 5 are provided as the energy source for the entire device. When using the device for water purification, it is usually necessary to use other means of transportation to transport it to the target water purification area. Therefore, the plurality of solar panels 5 are designed to be foldable, and the first telescopic component 2 is used to fold the grid 3 to facilitate the transportation of the device to the corresponding target water purification area. Among them, the second telescopic components 4 are provided in plurality, and each second telescopic component 4 is assembled with a solar panel 5 through a mounting plate 6. The plurality of solar panels 5 are staggered in their vertical height, so that the stacking of the plurality of solar panels 5 can be achieved by driving the second telescopic component 4. The second telescopic component 4 can be implemented as a linear motor. The plurality of solar panels 5 can be annular solar panels, such as Figure 1 As shown, the plurality of solar panels 5 include a first solar panel 501 , a second solar panel 502 and a third solar panel 503 . Taking the center of the main body 1 as a reference, the farther the solar panel is from the center of the main body 1 , the larger its diameter.

[0042] It should be noted that the main body 1 is a structure capable of floating on the water surface, including but not limited to a floating bed structure. Its first end surface 101 is located above the water surface, and its second end surface 102 is located below the water surface. When the device is in operation, a portion of the grid 3 is immersed in water, and plants for water purification are planted on the grid 3. The main body 1 is moved by the propeller 7 mounted on its second end surface 102. During this movement, the water purifier 8 performs electromagnetic water purification, the plants planted on the grid 3 perform biological water purification, and the solar panel 5 converts solar energy into electrical energy and provides power to various components that require electricity through the battery 12. This allows for autonomous water purification in the target water purification area without the need for human energy replenishment or other intervention.

[0043] In specific implementation, multiple solar panels 5 can be unfolded to power the entire device, and then the propeller 7 is used to move to the target water purification area. After arriving at the target water purification area, the length of the grid 3 is adjusted by the first telescopic component 2 to unfold the grid 3, and the plants pre-cultivated on the grid 3 or the corresponding water purification plants are cultivated on the grid 3 by manual labor in the target water purification area after arriving at the target water purification area. The water purification plants include but are not limited to plants such as duckweed, so as to achieve biological water treatment through water purification plants; the water purifier 8 uses electricity to generate magnetization to achieve physical water purification; some polyaluminum chloride is placed in the water purifier 8, and these polyaluminum chlorides can ensure a service life of up to one week. After use, the physical, chemical and biological multifunctional lake water purification device can be moved to the shore to be replaced, thereby achieving long-term chemical water purification. Complete the above operations.

[0044] In another embodiment, a water quality sensor can be configured on the main body 1. The water quality sensor is used to detect water quality parameters of the water body and transmit the water quality parameters to the user terminal in real time. The water purification effect can be viewed in real time through the user terminal. After all water quality parameters meet the standards, the physicochemical and biological multifunctional lake water purification device can be retrieved and used for water purification in another target water purification area.

[0045] In another embodiment, if Figure 3 and Figure 4 As shown, four propellers 7 are provided, all of which are jet propellers. The main body 1 is controlled by the four jet propellers at the bottom. The vacuum pump is moved and steered through holes in the four directions of the main body. Active forks retract and extend the grid via telescopic rods within the main body, and the solar panels retract and extend via slide rails below. The length of the grid is adjusted by rotating the screw rods with a motor. In wide lakes, the grid can be extended to its maximum length, while in narrow areas, the grid can be adjusted to an appropriate length depending on the situation.

[0046] In another embodiment, if Figure 3 As shown, the water purifier 8 is a hemispherical water purifier, into which some polyaluminium chloride is added. This polyaluminium chloride can ensure a service life of up to one week. After use, the multifunctional lake water purifier can be moved to the shore and replaced, thereby achieving long-term chemical water purification. The above operation is completed. During operation, the length of the grid 3 can be determined based on the range of action of the water purifier 8. Under normal conditions, the length of the grid 3 should cover the operating range of the water purifier 8, preferably consistent with the operating range of the water purifier.

[0047] In another embodiment, if Figure 1 As shown, the truss 3 includes a connecting frame 301, a mesh body 302, a mounting member 303 and a three-hole connecting rod 304. The connecting frames 301 are provided in plurality, and the three-hole connecting rod 304 is provided in two. The two ends of the multiple connecting frames 301 are respectively assembled on a three-hole connecting rod 304 through a mounting member 303, and the mesh body 302 is fixed by the multiple connecting frames 301.

[0048] In this embodiment, mounting member 303 may be a screw, which secures connecting frame 301 to three-hole connecting rod 304. Three-hole connecting rod 304 is a telescopic component that is pushed, pulled, and extended under the action of first telescopic assembly 2. Connecting frame 301 is used to assemble mesh 302, which serves as a carrier for growing plants. Plants grown in different target water purification areas may vary, depending on the water parameters of the target water purification area, and this embodiment does not specifically limit this.

[0049] The grid 3 has good scalability and a simple structure, thereby performing expansion and contraction processing on the water purification organisms.

[0050] In another embodiment, if Figure 1 As shown, the first telescopic assembly 2 includes a telescopic unit 201, an active fork 202 and a fork seat 203; wherein, the telescopic unit 201 is arranged on the main body 1, the active fork 202 is connected to one end of the three-hole connecting rod 304, the active fork 202 is connected to the fork seat 203, and the fork seat 203 is connected to the telescopic unit 201.

[0051] In this embodiment, a first telescopic component 2 corresponds to realizing the telescopic operation of a grid 3. When the grid 3 has two three-hole connecting rods 304, the telescopic unit 201, the active fork 202 and the fork seat 203 can be correspondingly set to two. The telescopic unit 201 is connected to the three-hole connecting rod 304 through the fork seat 203 and the active fork 202. The telescopic unit 201 can be a cylinder or other part that can realize telescopic operation. The two telescopic units 201 push together to make the paired three-hole connecting rods 304 push, pull and telescope, thereby completing the telescopic operation of the mesh body 302, so that the entire grid 3 can be adaptively telescopically adjusted according to the working range of the water purifier 8 or the water environment of the target water purification area, thereby realizing the automatic water purification function of the target water purification area.

[0052] In another embodiment, if Figure 1 As shown, the active fork 202 is connected to the fork seat 203 through the pin 204. The structure of the active fork 202 is as follows Figure 7 shown.

[0053] In another embodiment, if Figure 5 and Figure 6 As shown, the telescopic unit 201 includes a motor 2011, a screw seat 2012, a screw 2013, a screw 2014 and a movable plate 2015; wherein, the output end of the motor 2011 is connected to the screw 2013, the screw 2013 is rotatably assembled on the screw seat 2012, the screw 2014 is sleeved with the screw 2013, so that when the screw 2013 rotates, the screw 2014 moves horizontally in a set direction, the screw 2014 is connected to the movable plate 2015, the movable plate 2015 is movably assembled on the screw seat 2012, and the movable plate 2015 is connected to the fork seat 203 through a connecting piece 2016.

[0054] In this embodiment, the telescopic unit 201 is specifically designed. The operating principle of the telescopic unit 201 is as follows: The motor 2011 is a motor capable of forward and reverse rotation, including but not limited to a servo motor. When the motor 2011 rotates in the forward direction, it drives the screw rod 2013 in the forward direction, thereby causing the screw rod 2014, which is connected to the screw rod 2013, to expand outward. The screw rod 2014 pushes the fork seat 203 via the movable plate 2015, which in turn pushes the three-hole connecting rod 304 outward via the active fork 202, thereby extending the grid 3. Similarly, when the motor 2011 rotates in the reverse direction, the three-hole connecting rod 304 retracts inward, thereby retracting the grid 3. Among them, the movable stroke of the movable plate 2015 on the screw seat 2012 is the telescopic stroke of the telescopic unit 201. This structure can ensure that the threaded portion of the screw 2014 does not fall out of the screw 2013, and makes the telescopic range of the grid 3 adjustable, so that when the grid 3 is at the minimum length, it does not affect the plants growing therein.

[0055] In another embodiment, if Figure 1 and Figure 3 As shown, the grid 3 and the second telescopic components 2 are both provided in plurality, and the second telescopic components 2 are arranged in a ring array on the second end surface 102 .

[0056] Exemplarily, as shown in the figure, there are four grids 3, which correspond to eight second telescopic components 2. Two second telescopic components 2 drive one grid 3. Multiple grids 3 are arranged in a ring shape relative to the center of the main body 1, and the water purifier 8 is arranged in the middle position of the main body 1, thereby cleverly combining electromagnetic water purification technology with bioremediation technology to improve the purification effect.

[0057] In another embodiment, if Figure 8 As shown, the above-mentioned physical, chemical and biological multifunctional lake water purification device also includes a controller 9 and a positioner 10. The signal output end of the positioner 10 is connected to the signal input end of the controller 9, and the signal output end of the controller 9 is connected to the signal input ends of the first telescopic component 2, the second telescopic component 4, the propeller 7 and the water purifier 8. The battery 12 is connected to the controller 9 and the positioner 10 to provide a power source for the controller 9 and the positioner 10. The controller 9 is configured to perform the following Figure 9 Steps S10 and S20 are shown.

[0058] S10. According to the preset map information and navigation route, combined with the position information fed by the locator in real time, the propeller is controlled to operate so that the physical, chemical and biological multifunctional lake water purification device navigates according to the preset navigation route.

[0059] In this embodiment, before purifying the target water purification area, the corresponding map information can be drawn in advance and the navigation route can be set. These map information and the set navigation route are pre-configured in the controller 9, so that the controller 9 can control the operation of the propeller 7 in combination with the position information fed by the locator 10, so that it can travel according to the set navigation route in the target water purification area.

[0060] S20. If the first target area is reached, the first telescopic component is controlled to operate so that the overall diameter of the physico-chemical-biological multifunctional lake water purification device is smaller than the diameter of the first target area, so that it can pass through the first target area, and after passing through the first target area, the first telescopic component is controlled to operate so that the grid returns to the length of the normal water purification state; wherein, the first target area is an area with a diameter smaller than the overall diameter of the physico-chemical-biological multifunctional lake water purification device in the normal water purification state; in the normal water purification state, the length of the grid is the maximum grid length.

[0061] In this embodiment, the first target area is a special area that needs to be passed through on the journey from the shore to the target water purification area. The special area is determined through field investigation (such as using drone aerial photography to determine the geographical information of the target water purification area) before the device performs the water purification task. The determined first target area is marked in the preset map information. According to the position information feedback from the locator 10, it can be determined whether the first target area is passed. When passing through the first target area, the unfolded frame 3 will affect the passability of the entire device. Therefore, the first telescopic component 2 is controlled by the controller 9 to retract the frame 3 without interfering with the navigation of the entire device.

[0062] In another embodiment, if Figure 8 As shown, the physical, chemical and biological multifunctional lake water purification device also includes a power sensor 11, which is connected to the battery 12 and is used to collect the current power of the battery 12. The signal output end of the power sensor 11 is connected to the signal input end of the controller 9, and the controller 9 is configured to execute the following Figure 10 Steps S30 and S40 are shown.

[0063] S30: Compare the current power level fed in real time by the power sensor with the first target power level.

[0064] S40. When the current power is less than the first target power, the second telescopic assembly, the propeller, and the water purifier are controlled to stop working, and the first telescopic assembly is controlled to fully unfold the multiple solar panels until the current power reaches the second target power.

[0065] In this embodiment, a power sensor 11 is provided to determine the battery capacity of the battery 12 in real time. During specific implementation, a first target power level and a second target power level are set. The first target power level is the power level that signals the device to shut down due to the impending depletion of battery 12, and is generally set to a value between 5% and 15% of the total power level of battery 12. The second target power level is the power level required for the device to complete one cycle of water purification. A water purification cycle typically lasts for a set period of time. Typically, the water purifier 8 operates at set power parameters for 45 to 60 minutes, which is a single cycle of water purification. It is understood that the target water purification area includes multiple sub-water purification areas. Instead of remaining stationary at a fixed location, the device moves to the center of a set sub-water purification area and controls the water purifier 8 to complete one cycle of water purification. Therefore, the above design ensures that the device can complete one cycle of water purification in each sub-water purification area.

[0066] In another embodiment, the three-hole connecting rod 304 is made of a high-strength, high-toughness material, has high working strength and fatigue resistance, and has sufficient rigidity and toughness.

[0067] In another embodiment, the plurality of solar panels 5 are arc-shaped or ring-shaped solar panels, which have high efficiency in absorbing sunlight and can better absorb sunlight and shrink.

[0068] In another embodiment, the fork seat 203 is made of high-quality connecting and positioning parts and serves as the main body of the entire mechanical device. The fork seat has good sealing and positioning functions.

[0069] In another embodiment, the three-hole connecting rod 304 is a high-quality connecting rod with high strength, high rigidity, and good dynamic balance. For example, the three-hole connecting rod 304 is made of a high-strength, high-toughness material, has high working strength and fatigue resistance, and has sufficient rigidity and toughness.

[0070] In another embodiment, the connecting frame 301 is made of high-quality steel or aluminum alloy, and is processed by galvanizing, oxidation and electrostatic spraying. It has good strength and corrosion resistance, a high degree of modularity, and is easy to install and operate.

[0071] In another embodiment, the active fork 202 adopts a parallelogram structure and is made of alloy, which is not only strong and durable but also stretchable.

[0072] In another embodiment, the wires between the solar panel 5 and the battery 12 and / or the connecting wires between the battery 12 and other electronic components are made of TPU (polyurethane) mesh cable sheath, which has the characteristics of drop resistance, corrosion resistance, and good flexibility, and can better place plants.

[0073] Example 2:

[0074] Based on the physicochemical and biological multifunctional lake water purification device provided in Example 1, it is applied to a small reservoir. The physicochemical and biological multifunctional lake water purification device is controlled by four jet pump propellers at the bottom to move to the center of the reservoir, and then the solar panels are deployed to replenish electricity. The grid is fully deployed by rotating the screw rod by the motor. The grid can be extended to the maximum length in the center of the small reservoir and can be retracted to half at the edge. The grid is then deployed according to the length, and the thermal energy of the solar panels is converted into electricity for a sustainable bottom hemispherical water purification device. The hemispherical water purification device then begins to detect and adjust the water purification strength and the atomization strength of the water purification chemicals in real time. When the grid plants grow to a certain length, the physicochemical and biological water purification device is recycled, and based on the water quality test, it is decided whether to return to the small reservoir.

[0075] Example 3:

[0076] Based on the physicochemical and biological multifunctional lake water purification device provided in Example 1, it is applied to the waters of Poyang Lake. The physicochemical and biological water purification device is controlled to move into Poyang Lake by four jet pump propellers at the bottom. When the physicochemical and biological water purification device reaches the designated location in Poyang Lake where water purification is required, the solar panels are deployed to replenish the electricity, and the mesh frame is fully deployed by rotating the screw rod by the motor. The mesh frame is extended to the maximum length and deployed. The thermal energy of the solar panels is then converted into electricity for the sustainable bottom hemispherical water purification device. The hemispherical water purification device then begins to detect and adjust the water purification strength and the atomization strength of the water purification chemical substances in real time.
