The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the automatic urban river floating garbage collecting device of the embodiment includes a substrate steel frame 1, a streamline housing 2, a curved baffle 3, a solar panel 4, a fluorescent indicator lamp 5, a wind power device 6, an outer float 7, a filtering baffle 8, an electric eddy current rotor 9, a protective dome cover 10, an inner float 11, a cross bar 12, a hauling rope 13, a controller 14 and a storage battery 15;
the device comprises a matrix steel frame 1 as a device main body frame, a streamline housing 2, a curved baffle 3, a solar panel 4, a fluorescent indicator lamp 5, a wind power device 6, an outer floater 7, a filtering baffle 8, an electric vortex rotor 9, a protective dome cover 10, an inner floater 11, a cross rod 12, a steel bar 1, a river bank and a protective dome cover 10, wherein the streamline housing 2 is covered on the outer side of the matrix steel frame 1 and fixed with the matrix steel frame 1, the streamline housing 2 is provided with an opening, the curved baffle 3 is fixed on the opening of the streamline housing 2, the solar panel 4 is fixed on the matrix steel frame 1, the fluorescent indicator lamp 5 is fixed on the matrix steel frame 1 in four directions, the wind power device is fixed on the matrix steel frame 1, the outer floater 7 is fixed on the matrix steel frame 1 in four directions, the filtering baffle 8 is located in the center of the matrix steel frame 1 and connected with the matrix steel frame 1 through a steel bar, the controller 14 and the storage battery 15 are respectively installed on the base steel frame 1 and are positioned in the protective dome 10.
As shown in fig. 1, the curved baffle 3 of the present invention employs an elastic rubber sheet, a plastic sheet or a metal sheet, preferably having a certain elasticity such that it is easily deformed inward and hardly deformed outward. In the embodiment, a metal sheet (an iron sheet provided with an anticorrosive coating) is selected, when the curved baffle is produced, a flat metal sheet is made into a sheet structure (tile shape) with a certain radian, one end of the sheet structure is connected and fixed with two sides of an opening of the streamline housing, the arc concave surface faces the inner side of the opening of the streamline housing, and the thickness of the metal sheet is selected to be 0.1-1mm, so that the metal sheet is easy to deform. Once entering the opening, the floating garbage is difficult to separate under the action of the curved baffle 3 and can only continue moving inwards along with the water flow.
The curved baffle plate has the advantages that even if the device is not powered, the curved baffle plate 3 can still be driven by the water surface ripples to open and close; so that the floating garbage entering the opening can not be separated and can only move along with the water flow or the wind direction.
The streamline housing 2 is the housing of the whole device. The garbage can is preferably streamlined, so that the garbage can be prevented from being hung or clamped by the shell, and the material of the garbage can be light plastic; when the baffle plate and the curved baffle plate are made of the same material, the baffle plate and the curved baffle plate can be integrally formed. The streamline shell has a certain height, and the collection device during operation, streamline shell 2 needs the part to expose the surface of water, avoids rubbish to spill over or not from the opening entering device inside.
The streamline shells 2 can be installed on the base steel frame 1 in multiple sections, and an opening formed between every two adjacent streamline shells 2 at two ends is a horn-shaped inward contraction opening, so that garbage can conveniently enter the opening and can be collected; the number of the curved baffles 3 arranged on the two side wall surfaces of the opening is not limited, and at least one baffle is arranged on the left and right. The size of the opening can be determined according to the size of the target floating garbage to be collected, and in the case that the size of the curved baffle plate is 0.3-0.4 times the size of the narrowest part of the opening, the size of the narrowest part of the opening can be generally selected to be 1.1-1.5 times the size of the target floating garbage.
The filtering baffle 8 is used for preventing garbage from entering the electric vortex rotor 9, can be in a shape of a ring, a square or other closed loop, and has a certain height, and when the collecting device works, the filtering baffle 8 is partially exposed out of the water surface to prevent the garbage. The filtering baffle 8 may be made of plastic or metal with holes, or metal net or plastic net, and may be provided with single layer or multiple layers as required.
The solar panel 4, the controller 14 and the storage battery 15 are all located above the water surface during operation, but in order to prevent the solar panel 4, the controller 14 and the storage battery 15 from contacting with water due to waves or other factors, waterproof design is made on the solar panel 4, the controller 14 and the storage battery 15, for example, the solar panel 4 is placed in a waterproof casing package, and the waterproof casing of the solar panel 4 is open.
In a preferred embodiment of the present invention, the electric vortex rotor 9 has a plurality of pitched blades uniformly installed along the rotation axis, and the rotation direction of the electric vortex rotor 9 makes the surface water in the vicinity thereof flow downward. The controller 14 may be used to set the speed step of rotation.
The protective dome 10 is made of transparent material. The solar panel 4 may be disposed within a protective dome 10. The bottom end of the protective dome 10 is spaced from the water surface so that the bottom end of the protective dome 10 does not come into contact with floating debris.
In a preferred embodiment of the invention, the automatic floating waste collection device is provided with a perforated baffle at the bottom of the area between the streamlined outer casing 2 and the filtering baffle 8. When the device is recovered, the baffle with holes can filter water. If the baffle is not provided with the opening, the floating garbage can be taken away because the water flows out from the filtering baffle 8 and the opening to cause overlarge water flow during the recovery device.
As shown in fig. 1 and 2, the electric turbine rotor of the present invention is completely submerged when it is operated, which requires adjustment of the buoyancy of the inner and outer floats; the inner and outer floats may be foam or floating balls (hollow floating ball or floating ball made of low-density material)
When the device is used for automatic collection, the following method can be used for operation:
1) opening the protective dome 10, turning on the power supply of the device on the controller 14, and fastening the protective dome 10;
2) putting the device into water, and connecting the device to a cross bar 12 by using a traction rope 13;
3) under the action of sunlight and wind power, the solar cell panel 4 and the wind power device 6 charge the storage battery 15, after a certain electric energy threshold is reached, the storage battery 15 works for the electric vortex rotor 9, and surface water and lower-layer water form tiny convection;
4) the floating garbage flowing through the device gathers towards the middle of the device along with water, and the curved baffle 3 has the function of a valve which can only enter but not exit;
5) garbage is collected in the middle of the device, and the reticular filtering baffle 8 prevents the garbage from entering the electric vortex rotor 9;
6) after a period of time, the worker needs to recover the device;
7) untying the pull rope 13, opening the protective dome 10, turning off the power supply, and retrieving the device;
8) and (4) cleaning the garbage collected in the device, and carrying out overhaul and maintenance.
In general water areas, garbage is easy to gather at the near-shore positions such as two sides of a river channel or the edge of the water area, and therefore the device can be arranged at the near-shore positions at certain intervals, and a good garbage collecting effect can be achieved. The pull cord 13 is mainly used to restrain the location area of the device of the present invention to avoid drifting away.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
