The deterioration of water quality has not only affected the ecological environment, but also brought many troubles to people's production and life. Lake water bodies often contain various pollutants such as suspended matter, organic matter, nitrogen and phosphorus compounds, and heavy metals. If these pollutants are not effectively treated, they will cause long-term damage to the lake ecosystem and even threaten human health. In response to the problem of lake water pollution, a variety of water purification technologies have been studied and applied, mainly including physical precipitation, filtration, adsorption, chemical coagulation and precipitation. Water purification technology has evolved from traditional simple physical filtration methods to modern highly complex membrane technology.

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

[0039] Embodiment 1:

[0040] The present application embodiment provides a physical, chemical and biological 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, the solar panel 5 is fixedly installed 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, and is used to provide 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 of 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 is.

[0042] It should be noted that the main body 1 is a structure that can float on the water surface, including but not limited to a floating bed structure, wherein the first end face 101 is located above the water surface, the second end face 102 is located below the water surface, and part of the grid 3 is immersed in the water when the device is working, and plants for purifying water are planted on the grid 3. The main body 1 is moved by the action of the propeller 7 installed on its second end face 102. During the movement, the water purifier 8 plays an electromagnetic water purification role, the plants planted on the grid 3 play a biological water purification role, and the solar panel 5 converts solar energy into electrical energy and provides a power source for each component that needs electricity through the battery 12, thereby realizing autonomous water purification in the target water purification area without the need for human energy replenishment or other intervention operations.

[0043] In specific implementation, multiple solar panels 5 can be unfolded to power the entire device, and then the propeller 7 can be used to move to the target water purification area. After arriving at the target water purification area, the length of the grid 3 can be 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 can be cultivated on the grid 3 by artificially going to 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 generates magnetization through electrical energy to achieve physical water purification; some polyaluminum chloride is placed in the water purifier 8, and these polyaluminum chlorides can be used for 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, so as to achieve 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 checked in real time through the user terminal. After various 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, there are four propellers 7, and all of them are selected as jet pump propellers. The main body 1 is controlled to move by the four jet pump propellers at the bottom. The vacuum pump moves and turns through the holes in the four directions of the main body. The active fork retracts and expands the grid through the telescopic rod in the main body, and the solar panel retracts and expands through the lower slide rail. The length of the grid is adjusted by rotating the screw rod by the motor. In the wide waters of the lake, the grid can be extended to the maximum length, and in the narrow area, the grid length can be adjusted to a suitable length according to the situation.

[0046] In another embodiment, if Figure 3 As shown, the water purifier 8 is selected as a hemispherical water purifier, in which some polyaluminium chloride is added, and these polyaluminium chlorides can ensure a use time of up to one week. After use, the physical, chemical and biological multifunctional lake water purifier can be moved to the shore to replace it, so as to achieve long-term chemical water purification. Complete the above operation. During operation, the length of the grid 3 can be determined according to the scope of action of the water purifier 8. The length of the grid 3 should cover the working range of the water purifier 8 under normal conditions, and it is best to be consistent with the working range of the water purifier.

[0047] In another embodiment, if Figure 1 As shown, the grid 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 are provided in two. Both ends of the plurality of 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 plurality of connecting frames 301.

[0048] In this embodiment, the mounting member 303 may be a screw, and its function is to fix the connecting frame 301 on the three-hole connecting rod 304. The three-hole connecting rod 304 is a part that can achieve telescopic movement, and it can achieve push-pull telescopic movement under the action of the first telescopic assembly 2. The function of the connecting frame 301 is to assemble the mesh body 302, and the mesh body 302 is used as a carrier for planting plants. The plants planted in different target water purification areas may be different, which is specifically determined according to the water body parameters of the target water purification area, and this embodiment is not specifically limited here.

[0049] The grid frame 3 has good scalability and a simple structure, so that the water purification organisms can be expanded and contracted.

[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 a 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 working principle of the telescopic unit 201 is as follows: the motor 2011 is a motor capable of realizing 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 to rotate in the forward direction, thereby causing the screw rod 2014 sleeved with the screw rod 2013 to expand outward, and the screw rod 2014 pushes the fork seat 203 through the moving plate 2015, thereby pushing the three-hole connecting rod 304 to expand outward through the active fork 202, thereby realizing the extension of the grid 3. Similarly, when the motor 2011 rotates in the reverse direction, the three-hole connecting rod 304 is retracted inwardly, thereby realizing the retraction of 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 correspondingly arranged in the middle position of the main body 1, so that the electromagnetic treatment water purification technology and the bioremediation technology are cleverly combined 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, 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, and the controller 9 is configured to perform the following Fig. 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 along 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 physical, chemical and 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 its length in a normal water purification state; wherein, the first target area is an area whose diameter is smaller than the overall diameter of the physical, chemical and biological multifunctional lake water purification device in a normal water purification state; in a 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 in 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 fed back by the locator 10, it can be determined whether to pass through the first target area. 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 shrink 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 a 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 Fig.10 Step S30 and step S40 are shown.

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

[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, the battery capacity of the battery 12 is determined in real time by setting a power sensor 11. In the specific implementation, the first target power and the second target power are set, wherein the first target power is the warning power of the battery 12 that is about to run out of power and cause the device to shut down, which is generally set to any value between 5% and 15% of the total power of the battery 12, and the second target power is the power required for the device to complete a cycle of water purification tasks. A cycle of water purification tasks is generally a set time, and generally the water purifier 8 runs for 45 to 60 minutes at the set power parameters as a cycle of water purification tasks. It is understandable that the target water purification area includes multiple sub-water purification areas, and the device does not stay at a fixed location without moving, but moves to the center of the set sub-water purification area to control the water purifier 8 to complete a cycle of water purification tasks. Therefore, through the above design, it can at least ensure that the device can fully perform a cycle of water purification tasks in each sub-water purification area.

[0066] In another embodiment, the three-hole connecting rod 304 is made of high-strength and 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 uses high-quality connecting and positioning parts as the main body of the entire mechanical device, and 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 performance. For example, the three-hole connecting rod 304 is made of 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 modularization, 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, good flexibility, etc., and can better place plants.
