Description

Technical Field

[0001] This invention relates to the field of surface debris collection, and more particularly to a surface debris cleaning device that can improve water quality. Background Technology

[0002] Urban waterways often contain a lot of floating garbage, such as plastic bags, foam sheets, plastic beverage bottles, and other household and other waste. This garbage not only pollutes the water environment but also worsens water quality. Currently, cleaning up this floating garbage generally involves manually operating salvage boats, which consumes a lot of manpower and resources. To achieve automatic collection of floating garbage, CN202121663330.0 discloses an automatic surface garbage collection device that can automatically collect floating garbage on the water surface, greatly reducing the cost of manual salvage and cleaning. However, similar existing technologies have the following problems: some surface garbage gets stuck near the suction inlet of the recycling bin and cannot be sucked into the garbage bin. Moreover, when the garbage is collected to a certain extent, the garbage at the top will accumulate more and more, hindering the entry of new floating garbage. Eventually, garbage that cannot be sucked into the garbage recycling bin accumulates near the garbage bin, affecting its usability. Summary of the Invention

The piston rod moves up and down with the synchronous drive device, coordinating with the first and second one-way valves to transfer the garbage in the bin to the lower box, preventing garbage accumulation. The piston rod moves up and down with the synchronous drive device, coordinating with the ventilation switch and the exhaust switch to force air into the air explosion box, increasing the oxygen content in the water, improving water quality, and changing the air pressure of the float, thereby keeping the device and the water surface in optimal condition.

[0019] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] like Figure 1The device shown is a surface debris cleaning device for improving water quality. It includes a collection box 1 for sucking up debris. The collection box 1 comprises an upper box section for installing an auxiliary device and synchronously driving a piston rod to move up and down; a middle box section for generating negative pressure with the piston rod to suck up surface debris; and a lower box section for isolating the sucked-up debris. The upper box section is fixedly installed on the upper end of the middle box section. The lower end of the middle box section is detachably connected to the lower box section. A lower piston cylinder wall 4 is provided in the middle of the middle box section, and the inner wall of the lower piston cylinder wall 4 and the piston rod are also present. The lower end of piston rod 5 is slidably and sealed. The middle part of piston rod 5 is connected to synchronous drive device 3. The upper end of piston rod 5 is slidably and sealed to the inner wall of upper piston cylinder wall 7. A garbage inlet 2 is provided on the side of the middle box. A first one-way valve 12 is provided on the side of lower piston cylinder wall 4. A second one-way valve 13 is provided at the lower end of lower piston cylinder wall 4. The upper end of upper piston cylinder wall 7 is connected to and communicates with mounting support pipe 9 through vent pipe 8. The lower end of mounting support pipe 9 is connected to air explosion box 11 and float 10 through air exchange switch 14. An exhaust switch 15 is installed on float 10. An exhaust one-way valve is provided at the upper outlet position of upper piston cylinder wall 7. The exhaust one-way valve is connected to vent pipe 8. The upper piston part 55 of piston rod 5 is provided with a bowl-shaped sealing part. When running upward, the bowl-shaped sealing part and the front end of the bowl-shaped sealing part open and seal with the upper piston cylinder wall. When running downward, there is a gap between the bowl-shaped sealing part and the upper piston cylinder wall, and air flows into the front end of the bowl-shaped sealing part.

[0021] like Figure 1 , 2 As shown, the synchronous drive device 3 includes a motor 31, a first gear 32, a second gear 33, a limiting rocker arm 34, a drive rod 35, a swing rod 36, and an auxiliary paddle 37. The motor 31 is mounted on the upper surface of the upper housing. The first gear 32 is mounted on the output shaft of the motor 31. The second gear 33 is symmetrically mounted on both sides of the first gear 32. The drive rod 35 is mounted on the output shaft of the second gear 33. The other end of the drive rod 35 is rotatably hinged to the right end of the swing rod 36. The middle position of the swing rod 36 is rotatably hinged to the upper end of the limiting rocker arm 34. The lower end of the limiting rocker arm 34 is hinged to the rotating shaft of the upper housing. The auxiliary paddle 37 is detachably mounted on the front end of the swing rod 36.

[0022] like Figure 1 , 2As shown, the auxiliary lever 37 moves in a bucket-shaped trajectory under the drive of the swing rod 36, and the lowest point of the trajectory must not be lower than the water surface. The bucket-shaped trajectory begins with the auxiliary lever 37 not contacting the water surface at its highest point. As the drive rod 35 rotates, it drives the swing rod 36 forward. Simultaneously, due to the traction of the limiting rocker arm 34, the front end of the auxiliary lever 37 curves downward, with its lowest point extending below the water surface. Then, as the swing rod 36 moves backward, the auxiliary lever 37 retracts inward along the horizontal line, allowing it to slide garbage and debris into the garbage inlet. After the front end of the auxiliary lever 37 retracts inward along the horizontal line to its final position, it lifts upward at an angle, leaving the water surface, until it reaches its highest point, entering the next cycle. This trajectory allows the auxiliary lever 37 not only to slide garbage into the garbage bin but also to simultaneously push water inward, accelerating the water flow into the garbage bin and increasing the absorption and radiation range of the garbage bin.

[0023] like Figure 1 As shown, the internal space of the middle chamber is divided by the lower piston cylinder wall 4 into a suction chamber communicating with the waste inlet 2 and a piston chamber. The upper end of the suction chamber is connected to the waste inlet 2. A first one-way valve 12 is provided on both sides of the piston chamber. One end of the first one-way valve 12 is mounted on the inner wall of the lower piston cylinder wall 4 via a reset shaft. A second one-way valve 13 is provided at the lowest end of the piston chamber. One end of the second one-way valve 13 is mounted on the bottom inner wall of the middle chamber via a reset shaft. A limit stop is provided on the bottom inner wall of the middle chamber.

[0024] like Figure 4 As shown, the piston rod 5 includes a piston drive wheel 51, a piston rod body 52, a sliding groove 53, a lower piston part 54, and an upper piston part 55. The piston rod body 52 has transmission racks on both sides and a sliding groove 53 in the middle. A sliding retaining shaft is installed in the sliding groove 53 and is fixedly mounted on the central shaft of the first gear 32. The transmission racks on both sides of the piston rod body 52 intermittently mesh with the piston drive wheels 51 on both sides. The piston drive wheels 51 are symmetrically mounted on the rotating shafts of the second gears 33 and rotate synchronously with the first gear 32. The first gear 32 drives the two second gears 33 on both sides to rotate synchronously via a motor. The piston drive wheel 51 is a half-gear and is installed in a staggered manner. When the left piston drive wheel 51 rotates and meshes with the rack on the left side of the piston rod body 52, the piston rod body 52 moves upward. When the left piston drive wheel 51 rotates to the toothless part, the right piston drive wheel 51 meshes with the rack on the right side of the piston rod body 52, and the piston rod body 52 moves downward, forming a reciprocating motion. The lower end of the piston rod body 52 is provided with a lower piston part 54, which is sealed and slidably engaged with the inner wall of the piston cavity 14. The upper end of the piston rod body 52 is provided with an upper piston part 55, which is sealed and slidably engaged with the inner wall of the upper piston cylinder wall 7.

[0025] like Figure 1 , 5 As shown in Figure 6, when the lower piston 54 and the upper piston 55 move upward, the auxiliary lever 37 is lifted upward and does not contact the water surface. The second one-way valve 13 is closed at the limit stop, and the first one-way valve 12 is opened into the piston chamber. At this time, the suction chamber and the piston chamber are connected, and the debris on the water surface is sucked into the suction chamber from the outside. At the same time, the upper piston 55 moves upward and presses air into the mounting support pipe 9 through the vent pipe 8 and enters the air explosion box 11. The air explosion box 11 increases the oxygen content in the water.

[0026] When the lower piston 54 moves downward, the auxiliary paddle 37 moves downward and is retracted towards the garbage inlet 2. Upon contact with the water surface, the garbage is pushed into the garbage inlet 2. The first one-way valve 12 closes, and the second one-way valve 13 opens, connecting the internal space of the lower chamber with the piston chamber. The lower piston 54 continues to move downward, and the garbage is transferred into the lower chamber. Then, the lower piston 54 moves upward, repeating the above process to achieve garbage collection from the water surface.

[0027] like Figure 5 As shown, the mounting support pipe 9 includes an outer support pipe 91, an inner pipe 92, a limiting boss 93, and a sliding block 94. A mounting base is fixedly connected to the upper end of the outer support pipe 91, facilitating device fixation and preventing it from being washed away by water flow. The outer support pipe 91 is a hollow pipe structure, fitted with an inner pipe 92. A sliding block 94 is provided at the upper end of the inner pipe 92, and a Y-shaped sealing ring is provided between the sliding block 94 and the inner wall of the outer support pipe 91. The sliding block 94 and the inner wall of the outer support pipe 91 are sealed and can slide up and down. A limiting boss 93 is provided at the lower end of the outer support pipe 91, used to limit the lowest position of the inner pipe 92. The mounting support pipe 9 is a telescopic structure, allowing the garbage cleaning device to float up and down with the water level. A connector is provided at the upper end of the outer support pipe 91, communicating with the vent pipe 8. The vent pipe 8 is a foldable telescopic flexible hose.

[0028] A liquid level sensor (not shown) is installed at the garbage inlet 2. The liquid level sensor is electrically connected to a controller, and the controller is electrically connected to an air intake electronically controlled ventilation valve 14. The liquid level sensor detects the distance between the garbage inlet 2 and the water surface. When the distance is too high or too low, a sensor signal is triggered and sent to the controller, which then controls the air intake electronically controlled ventilation valve 14 to make adjustments. The installation and connection methods of the liquid level sensor and controller are existing technologies and will not be described in detail in this invention.

[0029] like Figure 6As shown, the lower end of the mounting support pipe 9 is connected to the ventilation switch 14 via a connector. The ventilation switch 14 includes a ventilation valve core 141, an electromagnetic switch 142, a return spring 143, and a valve core groove 144. The ventilation switch 14 is provided with a channel A, and channels B and C communicating with channel A. Channel B is connected to the air explosion box 11, and channel C is connected to the float 10. A valve core groove 144 is provided between channels B and C. A ventilation valve core 141 that can move left and right is installed in the valve core groove 144. Electromagnetic switches 142 are placed at both ends of the ventilation valve core 141. A return spring 143 is provided between the electromagnetic switch 142 and the ventilation valve core 141.

[0030] When the electromagnetic switch 142 on the C side is energized, the air exchange valve core 141 moves to the C side, connecting the B and A channels. The C channel is sealed by the air exchange valve core 141. At this time, the airflow pushed out by the upper piston cylinder wall 7 passes through the vent pipe 8 and the mounting support pipe 9 and is pressed into the air explosion box 11. The air explosion box 11 pressurizes air into the water, which can increase the oxygen content in the water and thus improve the water quality.

[0031] When the electromagnetic switch 142 of channel B is energized, the air exchange valve core 141 moves to the channel B side, connecting channel C and channel A. Channel B is sealed by the air exchange valve core 141. At this time, the airflow pressed out by the upper piston cylinder wall 7 passes through the vent pipe 8 and the mounting support pipe 9 and is pressed into the float 10. The float 10 is inflated, causing the garbage cleaning device to float upward. When the liquid level sensor at the garbage inlet 2 detects that the water level is 2-3 cm lower than the garbage inlet, the controller controls the electromagnetic switch 142 of channel C to de-energize, the air exchange valve core 141 to reset, and the electromagnetic switch 142 of channel B to be energized, so that the gas explosion box 11 can continuously ventilate normally.

[0032] When the water level drops due to drought, the level sensor detects that the garbage inlet is above the water level and vents air out through the vent switch 15, allowing the device to return to the optimal working water level.

[0033] The exhaust switch 15 has an exhaust channel E communicating with the float 10 and an exhaust channel D communicating with the exhaust channel E. The exhaust channel D is provided with an exhaust valve core groove 153, and an exhaust valve core 151 that can move left and right is installed in the exhaust valve core groove 153. An exhaust solenoid switch 152 is provided on the side of the exhaust valve core 151, and a return spring 143 is provided between the exhaust solenoid switch 152 and the exhaust valve core 151. When the liquid level sensor detects that the garbage inlet is higher than the water surface, the controller opens the exhaust solenoid switch 152, and the exhaust valve core 151 moves toward the exhaust solenoid switch 152, so that the exhaust channel D and the exhaust channel E are connected and exhaust is vented outward. After the exhaust work is completed, the exhaust solenoid switch 152 is de-energized, the exhaust valve core 151 is reset, and the exhaust channels D and E are blocked and sealed by the exhaust valve core 151.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
