[0020] The invention also provides an application of a floating device in water purification.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. When debris falls into the filter cartridge and the filter cartridge moves up and down with the help of the spring, the movement of the filter cartridge will drive the screw to move up and down through the mounting plate. The screw will be relatively displaced with the mounting plate, and the screw and the mounting plate are threaded to rotate the mounting plate. When the mounting plate rotates, the scraper is driven to rotate through the connecting rod. When the scraper rotates along the inner wall of the filter cartridge, as the filter cartridge moves up and down, the scraper will scrape off the debris adhered to the inner wall of the filter cartridge to ensure the normal use of the filter cartridge.

[0023] 2. The equipment is floated on the water surface with the help of the float, and then the drive motor is started. The output end of the drive motor makes the conveyor belt rotate in a cycle with the help of the belt. As the conveyor belt continues to rotate in a cycle, the debris floating on the water surface is picked up with the help of the feed plate. As the conveyor belt rotates in a cycle, the debris on the feed plate will fall into the filter cartridge.

[0024] 3. When the screw and the mounting plate move relative to each other in the vertical direction, the piston plate, sleeve and one-way valve cooperate to enable the sleeve to suck the water in the water body, and the water spray channel at the side end of the scraper will spray water to the inner wall of the filter cartridge, thereby clearing the blocked filter holes on the filter cartridge and ensuring the stable use of the filter cartridge.

[0025] 4. When the pressure sensor detects that the amount of debris falling this time is greater than the threshold value a, the annular hydraulic cylinder will be activated, and the output end of the annular hydraulic cylinder will move the annular push plate upward by a set distance, and then the annular push plate will retract. When the annular push plate moves upward and contacts the bottom end of the filter cartridge, the filter cartridge will move upward. When the filter cartridge moves upward, on the one hand, the rotation of the scraper and the upward movement of the filter cartridge cooperate to clean the inner wall of the filter cartridge. On the other hand, the distance between the scraper and the bottom end of the filter cartridge is reduced, and the scraper and the filter cartridge will squeeze the debris to discharge the residual water in the debris, so that the filter cartridge can collect more debris.

DETAILED DESCRIPTION

[0034] In order to facilitate understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0035] Embodiment 1

[0036] This embodiment discloses a floating device, such as Figures 1 to 3 As shown, it includes a float 1, a filter component 2 and a collection component 3 are arranged on the top of the float 1, a groove 4 is arranged on the upper end of the float 1, the bottom of the groove 4 is inclined, and the filter component 2 is located in the groove 4. First, the device is placed on the water surface, and the device is floated on the water surface with the assistance of the float 1, and then the debris in the water body is transported to the filter component 2 on the float 1 with the assistance of the collection component 3, and then the water in the debris is discharged with the assistance of the filter component 2, and the discharged water flows back into the water body along the groove 4, thereby completing the purification of the water body.

[0037] The filter assembly 2 includes a filter cartridge 201. The debris entering the filter cartridge 201 will filter the water in the debris with the assistance of the filter cartridge 201, so that the filter cartridge 201 can collect more debris in the water body, making the equipment have a better purification effect on the water body.

[0038] The collecting assembly 3 includes a conveyor belt 301, which is inclined. Both ends of the conveyor belt 301 are rotatably arranged on the floating body 1. A driving motor 302 is arranged on the floating body 1. A belt 303 is arranged between the driving motor 302 and the conveyor belt 301. The driving motor 302 provides power for the rotation of the conveyor belt 301 with the assistance of the belt 303. A feeding plate 304 is arranged on the conveyor belt 301, and a filter hole is arranged on the feeding plate 304. The filter cartridge 201 is located at the bottom of the top of the conveyor belt 301. The conveyor belt 30 The bottom end of 1 is located at the lower end of the float 1, and the driving motor 302 is started. The output end of the driving motor 302 drives the conveyor belt 301 to circulate with the assistance of the belt 303. During the circulatory rotation of the conveyor belt 301, the debris in the water body is brought up with the assistance of the feeding plate 304 on the conveyor belt 301, so that during the circulatory rotation of the conveyor belt 301, the debris in the water brought up by the feeding plate 304 will fall into the filter cartridge 201, and then the water in the debris is filtered with the assistance of the filter cartridge 201.

[0039] On the floating body 1, driving cylinders 305 are arranged on both sides of the conveyor belt 301, and driving rods 306 are arranged at the output ends of the driving cylinders 305. Nets 307 are arranged at the lower ends of the driving cylinders 305 and the driving rods 306, and a heavy ball 308 is arranged at the lower end of the net 307. The two driving cylinders 305 are arranged in an eight-shaped pattern. The driving cylinders 305 are started to extend the driving rods 306 at the output ends of the driving cylinders 305. After the driving rods 306 are extended, the net 307 will be opened, and a heavy ball 308 is arranged at the lower end of the net 307. Therefore, when the equipment floats on the water body, the net 307 is always in an open state with the assistance of the heavy balls 308. With the assistance of the two nets 307, the debris in the water body is gathered at the conveyor belt 301, so that the feeding plate 304 on the conveyor belt 301 can pick up the debris in the water body, thereby improving the convenience of using the equipment.

[0040] During use of the present invention, the device is placed in the water body to be purified, and the device is floated on the water surface with the assistance of the float 1, and then the drive motor 302 is started. The output end of the drive motor 302 causes the conveyor belt 301 to circulate with the assistance of the belt 303, and at the same time, the drive cylinder 305 is started to extend the drive rod 306 at the output end of the drive cylinder 305. After the drive rod 306 is extended, the blocking net 307 will be opened, and a heavy ball 308 is provided at the lower end of the blocking net 307. Therefore, when the device floats on the water body, the blocking net 307 is always in an open state with the assistance of the heavy ball 308, and the debris in the water body is gathered at the conveyor belt 301 with the assistance of the two blocking nets 307.

[0041] As the conveyor belt 301 continues to circulate, the debris floating on the water surface is picked up with the assistance of the feeding plate 304. As the conveyor belt 301 circulates, the debris on the feeding plate 304 will fall into the filter cartridge 201, and the water in the debris that has fallen into the filter cartridge 201 will pass through the filter cartridge 201 and fall into the groove 4. Since the groove 4 is in an inclined state, the water that has fallen on the groove 4 will slide back into the water body, thereby completing the purification of the water body.

[0042] Embodiment 2

[0043] Based on a floating device of the first embodiment, during use, when filtering water of debris in the filter cartridge 201, the water in the debris in the filter cartridge 201 cannot be completely squeezed out, and the debris needs to be squeezed manually to make the filter cartridge 201 collect more debris, which is time-consuming and labor-intensive. At the same time, the filter holes of the filter cartridge 201 are easily blocked, thereby affecting the use of the filter cartridge 201. Therefore, the following solution is proposed:

[0044] like Figures 1 to 7 As shown, a spring 213 is arranged between the filter cartridge 201 and the float 1, and the upper end of the spring 213 is connected to the pressure sensor 211. An annular hydraulic cylinder 214 is arranged at the upper end of the mounting seat 202, and an annular push plate 215 is arranged at the output end of the annular hydraulic cylinder 214. During the circulation of the conveyor belt 301, with the assistance of the feeding plate 304, the debris on the conveyor belt 301 will intermittently fall into the filter cartridge 201. Since the spring 213 is arranged at the lower end of the filter cartridge 201, each time the debris falls, the filter cartridge 201 will move downward and then move upward. After the annular hydraulic cylinder 214 is started, the output end of the annular hydraulic cylinder 214 will move the annular push plate 215 upward. When the annular push plate 215 moves upward and contacts the bottom of the filter cartridge 201, the annular push plate 215 will move the filter cartridge 201 upward. The pressure sensor 211 can detect the pressure between the filter cartridge 201 and the spring 213. With the assistance of the pressure sensor 211, the amount of debris falling each time can be indirectly detected.

[0045] The upper end of the float 1 is provided with a mounting seat 202 at the lower end of the filter cartridge 201, a mounting plate 203 is provided in the filter cartridge 201, a screw 204 is provided at the lower end of the mounting plate 203, a piston plate 205 is provided at the lower end of the screw 204, a channel 206 communicating with each other is provided on the piston plate 205 and the screw 204, a one-way valve 207 is provided in the channel 206, a mounting plate 208 is provided in the filter cartridge 201, a connecting rod 209 is provided on the outer side of the mounting plate 208, a scraper 210 is provided at the end of the connecting rod 209, the screw 204 passes through the mounting plate 208, the screw 204 and the mounting plate 208 are threadedly matched, a pressure sensor 211 is provided at the lower end of the filter cartridge 201, a sleeve 212 is rotatably provided at the lower end of the mounting plate 208, the sleeve 212 passes through the filter cartridge 201 and is arranged on the float 1, the sleeve 212 passes through the float 1, and the filter cartridge 20 When the filter cartridge 201 moves up and down with the help of the falling of debris or the annular hydraulic cylinder 214, the filter cartridge 201 drives the screw rod 204 to move up and down through the mounting plate 203. During the process of the screw rod 204 moving up and down, the screw rod 204 will be threadedly matched with the mounting plate 208, so that the mounting plate 208 rotates. The rotation of the mounting plate 208 will drive the rotation of the scraper 210 through the connecting rod 209. The rotation of the scraper 210 cooperates with the up and down movement of the filter cartridge 201, so that the scraper 210 can scrape the inner wall of the filter cartridge 201 to prevent the debris from adhering to the inner wall of the filter cartridge 201. When the screw rod 204 and the sleeve 212 move relatively, the piston plate 205 cooperates with the one-way valve 207 to allow the water at the lower end of the float 1 to enter the sleeve 212, and then the water in the sleeve 212 enters the upper end of the piston plate 205 through the channel 206.

[0046] The screw 204 passes through the mounting plate 208 and is inserted into the sleeve 212. The piston plate 205 is located in the sleeve 212. The mounting plate 208, the connecting rod 209 and the scraper 210 are provided with interconnected water spray channels 216. There are multiple water spray channels 216 in the scraper 210. The water spray channels 216 are connected to the sleeve 212. The water entering the upper end of the piston plate 205 will enter the water spray channel 216, and then the water in the water spray channel 216 will be sprayed outward. As the scraper 210 rotates, the water sprayed from the water spray channel 216 at the side end of the scraper 210 will act on the filter holes of the filter cartridge 201, thereby clearing the blocked filter holes, thereby improving the convenience of using the equipment.

[0047] A drainage hole 217 is provided at the lower end of the mounting seat 202. There are multiple drainage holes 217, and the multiple drainage holes 217 are evenly arranged. A limiting hole 218 is provided at the lower end of the filter cartridge 201. A limiting plate 219 is provided on the outer side of the sleeve 212. The limiting plate 219 slides in the limiting hole 218. The water discharged from the filter cartridge 201 will fall from the center of the annular hydraulic cylinder 214, and the falling water will fall into the mounting seat 202. The mounting seat 202 is provided with a drainage hole 217, and the water in the mounting seat 202 is discharged with the assistance of the drainage hole 217.

[0048] The scraper 210 has a trapezoidal cross-section, and an inwardly concave arc is provided at the lower end of the scraper 210. The scraper 210 fits against the inner wall of the filter cartridge 201, and the water spray channel 216 in the scraper 210 is aligned with the inner wall of the filter cartridge 201. When the scraper 210 and the filter cartridge 201 move relative to each other in the vertical direction, the debris at the bottom of the scraper 210 and the filter cartridge 201 will be squeezed, so that the water in the debris is discharged, and the filter cartridge 201 collects more debris, thereby improving the convenience of using the equipment.

[0049] During use of the present invention, the device is placed in the water body to be purified, and the device is floated on the water surface with the assistance of the float 1, and then the drive motor 302 is started. The output end of the drive motor 302 causes the conveyor belt 301 to circulate with the assistance of the belt 303, and at the same time, the drive cylinder 305 is started to extend the drive rod 306 at the output end of the drive cylinder 305. After the drive rod 306 is extended, the blocking net 307 will be opened, and a heavy ball 308 is provided at the lower end of the blocking net 307. Therefore, when the device floats on the water body, the blocking net 307 is always in an open state with the assistance of the heavy ball 308, and the debris in the water body is gathered at the conveyor belt 301 with the assistance of the two blocking nets 307.

[0050] As the conveyor belt 301 continues to circulate, the debris floating on the water surface is picked up with the assistance of the feeding plate 304 . As the conveyor belt 301 circulates, the debris on the feeding plate 304 falls into the filter cartridge 201 .

[0051] The debris that falls into the filter cartridge 201 will cause the filter cartridge 201 to move downward, and then with the assistance of the spring 213, the filter cartridge 201 will move up, and the more debris that falls into the filter cartridge 201, the greater the downward movement distance of the filter cartridge 201, and the greater the change in the detection value of the pressure sensor 211. When the conveyor belt 301 transports the debris, the debris assisted by the feed plate 304 will intermittently fall into the filter cartridge 201, causing the filter cartridge 201 to move up and down intermittently.

[0052] When debris falls into the filter cartridge 201 and with the assistance of the spring 213, the filter cartridge 201 moves up and down. The movement of the filter cartridge 201 will drive the screw 204 to move up and down through the mounting plate 203. The screw 204 will be relatively displaced with the mounting disk 208, and the screw 204 and the mounting disk 208 are threadedly matched. Therefore, as the screw 204 moves up and down, the mounting disk 208 will reciprocate. When the mounting disk 208 rotates, the scraper 210 is driven to rotate through the connecting rod 209. When the scraper 210 rotates along the inner wall of the filter cartridge 201, as the filter cartridge 201 moves up and down, the scraper 210 will scrape off the debris adhered to the inner wall of the filter cartridge 201 to ensure the normal use of the filter cartridge 201.

[0053] When the screw 204 and the mounting plate 208 move relative to each other in the vertical direction, the piston plate 205 and the sleeve 212 also move relative to each other. Therefore, the piston plate 205, the sleeve 212 and the one-way valve 207 cooperate to enable the sleeve 212 to suck the water in the water body. The water in the water body will enter the sleeve 212, and then the water in the sleeve 212 will pass through the one-way valve 207 and the channel 206 to enter the upper end of the piston plate 205, and then the water will enter the water spray channel 216. The water spray channel 216 at the side end of the scraper 210 will spray water toward the inner wall of the filter cartridge 201, thereby clearing the blocked filter holes on the filter cartridge 201 and ensuring the stable use of the filter cartridge 201.

[0054] With each drop of debris, the detection value of the pressure sensor 211 will increase. Each increase in the detection value of the pressure sensor 211 corresponds to the amount of debris. Therefore, the amount of debris falling each time can be detected with the assistance of the pressure sensor 211. When the pressure sensor 211 detects that the amount of debris falling this time is greater than the threshold value a, the annular hydraulic cylinder 214 will be activated, and the output end of the annular hydraulic cylinder 214 will move the annular push plate 215 upward by a set distance, and then the annular push plate 215 will retract. When the annular push plate 215 moves upward and contacts the bottom end of the filter cartridge 201, the filter cartridge 201 will be moved upward. The filter cartridge 201 moves upward. On the one hand, the scraper 210 rotates and cooperates with the upward movement of the filter cartridge 201 to clean the inner wall of the filter cartridge 201. On the other hand, the distance between the scraper 210 and the bottom end of the filter cartridge 201 is reduced. The scraper 210 and the filter cartridge 201 will squeeze the debris, so that the residual water in the debris is discharged, so that the filter cartridge 201 collects more debris, and after the annular push plate 215 retracts, the filter cartridge 201 moves downward. At this time, the water spray channel 216 sprays water. With the rotation of the scraper 210 and the downward movement of the filter cartridge 201, the water sprayed from the water spray channel 216 can dredge the filter holes of the filter cartridge 201.

[0055] When the detection value of the pressure sensor 211 increases and exceeds the threshold value b, it indicates that the amount of debris collected in the filter cartridge 201 is close to saturation. At this time, the equipment control starts the annular hydraulic cylinder 214, causing the annular push plate 215 to rise to the limit distance and then retract, so that the scraper 210 cooperates with the filter cartridge 201 to strongly squeeze the debris in the filter cartridge 201 to reduce the moisture content of the debris in the filter cartridge 201. After squeezing, when the equipment returns to its initial state, the detection value of the pressure sensor 211 will be lower than the threshold value b. At this time, the equipment will continue to operate to collect debris in the water body until the detection value of the pressure sensor 211 is always greater than the threshold value b. The equipment stops operating. At this time, the equipment will send a signal to the staff to move the equipment to the shore to clear the debris in the filter cartridge 201.
