Description

[0002] With the development of social production, rivers in all countries of the world are facing different degrees of pollution from industry, agriculture, life, etc. A large amount of sewage is directly discharged into the river, resulting in serious deterioration of the river's ecological environment. A large amount of floating pollutants float on the surface of the river, causing eutrophication of the water body, causing algae and other plankton to reproduce rapidly, the dissolved oxygen content of the water body to decrease, the water quality to deteriorate, and fish and various microorganisms cannot survive in the water.

[0003] At present, the way to deal with floating objects on the surface of the river is generally for staff to drive salvage boats on the river to salvage the dirt floating at any position. This method is not only time-consuming and labor-intensive, but also has average results and high costs. As for the treatment of river silt, most of the methods are to block the river, then drain the water from the river, and finally pump out the silt as a whole for treatment before discharging it into the river.

[0020] 1. The river ecological restoration equipment provided by the present invention comprises a guide structure and a filter assembly which are arranged in linkage. The structural design of the guide structure enables the water on the water surface of the river to flow through the water flow channel. The water flow drives the impeller to rotate and then enters the outer shell of the filter assembly. The rotation of the impeller drives the filter assembly to operate to filter and remove impurities from the water, thereby causing the impurities in the water flow to be discharged and finally fall into the collection box from the slag discharge port, thereby achieving the effect of efficiently cleaning the water surface of the river. In addition, the rotation of the impeller drives the operation of the generator set, which also reflects the technical effect of energy saving and environmental protection of the present invention.

When it moves downward by gravity, the driving structure drives the driven gear to rotate, thereby moving the entire device forward. When the contact switch contacts the connecting shaft, the solenoid valve opens for a set period of time, allowing the pollutants to be discharged from the discharge port and fall into the collection boat. Then, under the elastic force of the tension spring, the collection box moves upward, and the driven gear does not rotate during the upward movement, thereby realizing the movement of the entire device. The power source of the entire moving process indirectly relies on the power of the river water flow, which reflects the technical advantages of the ingenious, practical, energy-saving and environmentally friendly structural design of the present invention.

[0022] 3. In the present invention, since the liquid replacement component and the pumping component are arranged in linkage, and the push-pull rod is driven to move downward during the downward movement of the collecting box, the sewage in the lower part of the river channel and the repair liquid in the storage box are sucked into the cylinder and mixed, and when the collecting box moves upward, the push-pull rod moves upward, and the sludge in the cylinder is discharged from the liquid outlet through the discharge pipe into the annular pipe, and then discharged from multiple outlets into the shell to impact on the fan blades to rotate the rotating tube, and then the sludge is discharged from the water outlet into the mesh cylinder. Under the action of the spiral diffusion blades, the sludge mixed with the repair liquid is diffused at the bottom of the river channel for repair, and when the rotating tube rotates, the bristles at the edge of the spiral diffusion blades can clean the mesh cylinder.

The contact switch is electrically connected to the controller 42. When the contact switch contacts the connecting shaft 6, the controller 42 opens the solenoid valve.

[0041] In order to facilitate the control of the thrust generated by the water flow on the guide structure 14, it is necessary to control the depth of the guide plate 14-1 extending into the water according to the speed of the water flow. Therefore, a water flow sensor 14-9 electrically connected to the controller 42 is provided on the guide plate 14-1; one of the first guide rods 27 is provided with a scale line.

[0042] In order to facilitate the collection and transfer of pollutants in the collection box 18, a pair of unhooks are provided at the bottom of the plate frame 1, and the unhooks are connected to one end of the pull rope 34, and the other end of the pull rope 34 is connected to the collection boat 33 floating on the water surface of the river 43.

[0043] In order to improve the applicability of the device, a solar panel 36 for supplying power to the battery 35 is also provided on the panel frame 1 .

[0044] The specific working principle of the present invention is as follows: first, according to the principle that the moving direction of the equipment is consistent with the flow direction of the water flow, the equipment is assumed to be above the river channel 43, and the driving wheel 4 is located at the rear side of the equipment, and then the handle 14-8 is turned. When the water flow sensor 14-9 measures the water surface flow rate, the position of the scale line on the first guide rod 14-6 is recorded, and the handle 14-8 is turned according to the water flow rate, so that the guide plate 14-1 extends into the appropriate depth underwater, and the butterfly bolt is turned to adjust the resistance applied by the rubber damping head to the driving wheel 4, so that the equipment will not move with the water flow in a natural state; the time for opening the solenoid valve each time is set by the controller 42.

[0045] After the water flows through the water channel, it drives the impeller to rotate, the generator set 15 starts to generate electricity, the rotating shaft 16-2 in the filter component 16 starts to rotate, and then the water flows into the outer shell 16-1 of the filter component 16 for impurity removal, and the pollutants in the water enter the collection box 18, and the cleaned water falls into the river channel 43.

[0046] As the amount of pollutants in the collection box 18 increases, the gravity on the tension spring 28 gradually increases, and the collection box 18 gradually moves downward. The toothed plate 22-7 in the driving structure 22 on the side wall of the collection box 18 drives the driven gear 7 to rotate, thereby realizing the movement of the device. When the contact switch contacts the connecting shaft 6, the solenoid valve opens for a set period of time, so that the pollutants are discharged from the discharge port and fall into the collection boat 33, and then under the elastic force of the tension spring 28, the collection box 18 moves upward, and the toothed plate 22-7 cannot drive the driven gear 7 to rotate during the upward movement.

[0047] In addition, since the liquid replacement component 30 and the pumping component 31 are arranged in linkage, and the collection box 18 moves downward, the push-pull rod 31-7 is driven to move downward, so that the sewage in the lower part of the river channel 43 and the repair liquid in the storage box 26 are sucked into the cylinder 31-1 and mixed; and when the collection box 18 moves upward, the push-pull rod 31-7 moves upward, and the sludge in the cylinder 31-1 is discharged from the liquid outlet 31-3 and discharged into the annular pipe 30-7 through the discharge pipe 31-5, and then discharged from multiple outlets 30-8 into the shell 30-2 to impact on the fan blades 30-4 to rotate the rotating tube 30-3, and then the sludge is discharged from the water outlet 30-5 into the net tube 30-1. Under the action of the spiral diffusion blades 30-6, the sludge mixed with the repair liquid spreads at the bottom of the river channel 43 to repair the bottom of the river channel 43, and when the rotating tube 30-3 rotates, the bristles at the edge of the spiral diffusion blades 30-6 can clean the net tube 30-1.

[0048] It should be noted that when the water surface of the river channel 43 is not flowing, first adjust the depth of the guide plate 14-1 below the water surface, then control the telescopic end of the electric push rod 22-3 to retract, so that the transmission mechanism deviates from the driven gear 7, then start the hydraulic cylinder 37 to make the propeller 40 extend into the water, and then start the drive motor 39 to drive the device to move forward in the direction of the bending structure of the guide plate 14-1.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
