[0004] Existing water pollution detection and purification devices are mostly completed by sampling water bodies when in use. However, when monitoring water bodies for a long time on demand, most of them need to set up the structure for a long time. It is difficult to install the detection equipment in the deeper water of the lake, which is inconvenient to use. Moreover, most of them have relatively single functions. When collecting water bodies, suction will be generated, which is easy to cause impurities to clog and thus cannot work normally, and frequent cleaning is required;

[0005] Based on the above-mentioned situation, we found that it is difficult for the water pollution detection and purification devices in the prior art to avoid the above problems at the same time. Therefore, we proposed a water pollution detection and purification device that can monitor water pollution for a long time, is easy to set up or recycle, and can also avoid floating pollutants on the water surface affecting the water quality detection process. It can also collect impurities for water purification and its use method. Summary of the invention

[0006] The purpose of the present invention is to target an existing water pollution detection and purification device and its use method, which has the advantages of being able to monitor water pollution for a long time, being easy to set up or recycle, and preventing floating pollutants on the water surface from affecting the water quality detection process, and being able to collect impurities for water purification.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: a water pollution detection and purification device, comprising a structural plate, an air bag is bolted to the bottom of the structural plate, a top frame is bolted to the top of the structural plate, a layer frame is bolted to the inner side of the top frame, a detection component is arranged on the inner side of the layer frame, a floating sheet is arranged on the outer side of the structural plate, a ring net is bolted to the bottom of the floating sheet, an anchor box is arranged at the bottom of the detection component, a reduction motor is arranged on the outer side of the floating sheet, and a water wheel is bolted to the output end of the reduction motor;

[0008] The detection assembly includes a detection tube, on the inner side of which a thermometer, a photometer and a turbidity meter are installed, the inner side of the detection tube is slidably connected to a piston plate, the top of the piston plate is rotatably connected to a screw rod, the top of the inner side of the detection tube is slidably connected to the screw rod, the top of the outer side of the detection tube is bolted to a support ring, the top of the support ring is bolted to a side plate, the inner side of the side plate is rotatably connected to a threaded sleeve, and the inner side of the threaded sleeve is threadedly connected to the screw rod.

[0009] By adopting the above technical solution, air bags and floating sheets are provided to provide buoyancy for the structure. The air bags support the top structural plate to float on the water surface. The floating sheets are used to limit the air bags and structural plates on the outside to prevent the structure from overturning when the wind and waves are strong. The arranged layer frame cooperates with the top frame to facilitate the installation and fixation of the detection components. The arranged annular net is used to cooperate with the reduction motor and the water wheel. When the reduction motor drives the water wheel to rotate, it will stir the surrounding water flow and the pollutants floating on the water surface, and make them fall into the inside of the annular net to collect the pollutants, which can have the effect of purifying the water body and prevent the impurities from clogging the structure and causing it to fail to operate normally. The arranged anchor When the box is filled with water, it can be used as a counterweight to anchor the structure. When the inside is drained and hollow, the structure is stopped from being fixed. At this time, the structure can be dragged to change its position or to be recovered. The detection component is used to detect the water body. The bottom of the detection tube is immersed in the water body. When the screw sleeve is driven to rotate by the control motor, the screw rod connected to it will rise vertically. At this time, the piston plate connected to it will also move up and cause the negative pressure inside the detection tube to draw water into it. At this time, the water temperature, color, turbidity and other parameters can be measured by thermometer, photometer and turbidity meter. After the detection is completed, the control motor can be reversed to discharge the water.

[0010] The present invention is further configured as follows: a control motor is installed on the outer side of the detection tube, a transmission pulley is bolted to the output end of the control motor and the outer side of the screw sleeve, and the two transmission pulleys are connected by a transmission belt.

[0011] By adopting the above technical solution, by setting a control motor in conjunction with a transmission pulley, the screw sleeve can be driven to rotate, thereby achieving the effect of adjusting the vertical position of the structure.

[0012] The present invention is further configured as follows: a narrow frame is bolted to the outer side of the detection tube, the inner side of the narrow frame is bolted to the control motor, and a light shielding sheet is bonded to the outer side of the detection tube.

[0013] By adopting the above technical solution, a narrow frame is provided to install the control motor on the outside of the detection tube, and the provided shading sheet can reduce the influence of external ambient light on the detection result.

[0014] The present invention is further configured as follows: a photovoltaic panel is installed on the top of the floating sheet, the photovoltaic panel is externally connected to a controller, a battery and an inverter, the surfaces of the floating sheet and the structural plate are bolted with connecting buckles, and the outer side of the connecting buckles is bolted with connecting ropes.

[0015] By adopting the above technical solution, photovoltaic panels can be set up to facilitate the cooperation with the controller, batteries and inverter to supply energy to the structure to a certain extent. The set connecting buckles and connecting cables can facilitate the installation of the structure. When the structure collides, the floating sheet will directly contact the collision position, thereby reducing the damage to the structural plate and the structure thereon.

[0016] The present invention is further configured as follows: a guide bucket is provided on the inner side of the annular net, a hanging ring is bolted on the outer side of the floating sheet, a connecting chain is bolted on the outer side of the hanging ring, and the bottom of the connecting chain is fixedly connected to the anchor box.

[0017] By adopting the above technical solution, by setting a guide bucket, it is easy to limit the impurities entering the annular net, making it difficult for them to float out from the inside of the annular net, so as to facilitate later collection by personnel. The scraper ring is used in conjunction with the connecting chain to fix the anchor box and the floating sheet.

[0018] The present invention is further configured as follows: a wheel frame is bolted to the top of the floating sheet, the top of the wheel frame is bolted to a reduction motor, and the bottom of the wheel frame is rotatably connected to a water wheel.

[0019] By adopting the above technical solution and arranging a wheel frame, it is convenient to install and support the reduction motor and the water wheel, making the structure more stable.

[0020] The present invention is further configured as follows: a liquid pump is bolted to the top of the inner side of the anchor box, the liquid pump is a centrifugal pump capable of reverse extraction, and an input end of the liquid pump penetrates the anchor box and is bolted to the anchor box.

[0021] By adopting the above technical solution and providing a liquid pump, it is convenient to inject water into the interior of the anchor box or to pump out the water used for the counterweight.

[0022] The present invention is further configured as follows: an extension tube is bolted to the output end of the liquid pump, and a side of the extension tube away from the liquid pump is arranged at the bottom of the inner side of the anchor box.

[0023] By adopting the above technical solution, the residual weight water in the liquid pump can be easily pumped out by arranging an extension pipe.

[0024] The present invention is further configured as follows: an isolation plate is bolted to the top of the inner side of the anchor box, the isolation plate is arranged on the outer side of the liquid pump, and an interception net is provided at the input end of the liquid pump and the bottom of the detection tube.

[0025] By adopting the above technical solution, by setting up an isolation plate, the liquid pump can be easily protected to avoid structural damage caused by long-term immersion in water, and the interception net can prevent impurities from blocking the flow of water.

[0026] A method for using a water pollution detection and purification device comprises the following steps:

[0027] S1. First, the structure is towed by a vehicle to a place where water quality is continuously tested. Then the anchor box is put into the water and filled with water until the structure is anchored. The airbag provides buoyancy to keep the structural plate on the water surface. The floating sheet with its own buoyancy also floats on the water surface at this time.

[0028] S2. When testing is required, the control motor is started, and the screw sleeve connected to it through the transmission pulley will also rotate until the control screw rod is vertically lifted and lowered along the screw sleeve, and the piston plate is driven to form negative pressure inside the detection tube. Water in the environment is drawn into the detection tube, and the water quality is tested by the thermometer, photometer and turbidity meter. After the test is completed, the control motor is reversed to squeeze the water out of the detection tube;

[0029] S3. The reduction motor starts to drive the water wheel to rotate. The water wheel will interfere with the surrounding water flow and push the garbage floating on the water surface together with the water flow to the inner side of the ring net and be intercepted by the guide bucket. When recovery is needed, the water in the anchor box is extracted from the extension pipe through the liquid pump and discharged. At this time, the anchor box is light in weight and will not pull the structure, and it can be recovered by traction of the carrier.

[0030] In summary, the present invention has the following beneficial effects:

[0031] The airbags and floating sheets are provided to provide buoyancy for the structure. The airbags support the top structural plate to float on the water surface. The floating sheets are used to limit the airbags and structural plates on the outside to prevent the structure from overturning when the wind and waves are strong. The layer racks and the top racks are convenient for installing and fixing the detection components. The ring net is used to cooperate with the reduction motor and the water wheel. When the reduction motor drives the water wheel to rotate, it will stir the surrounding water flow and the pollutants floating on the water surface, and make them fall into the inside of the ring net to collect the pollutants, which can purify the water body and prevent the impurities from clogging the structure and causing it to fail to operate normally. The anchor box is injected inside When there is water, it can be used as a counterweight to anchor the structure. When the internal drainage is hollow, the structure is stopped from being fixed. At this time, the structure can be dragged to change its position or to recover it. The detection component is used to detect the water body. The bottom of the detection tube is immersed in the water body. When the screw sleeve is driven to rotate by the control motor, the screw rod connected to it will rise vertically. At this time, the piston piece connected to it will also move up and cause the negative pressure inside the detection tube to draw water into it. At this time, the water temperature, color, turbidity and other parameters can be measured by thermometer, photometer and turbidity meter. After the detection is completed, the control motor can be reversed to discharge the water. BRIEF DESCRIPTION OF THE DRAWINGS

The setting of the connecting buckle 16 and the connecting rope 17 can facilitate the installation of the structure. When the structure collides, the floating sheet 6 will directly contact the collision position, thereby reducing the damage to the structural plate 1 and the structure thereon.

The extension pipe 23 can be easily used to extract the residual counterweight water in the liquid pump 22.

[0050] like Figure 3 As shown, an isolation plate 24 is bolted to the top of the inner side of the anchor box 8, and the isolation plate 24 is arranged on the outer side of the liquid pump 22. An interception net 25 is provided at the input end of the liquid pump 22 and the bottom of the detection tube 501.
