[0028] refer to Figures 1 to 8 As shown, a device for collecting garbage on the water surface includes a device body 1, a collection channel, a collection mechanism 3, a gate mechanism 4, a water filtration and receiving mechanism, a drainage mechanism and a driving mechanism. The device body 1 is provided with a collection channel, a collection mechanism 3, a gate mechanism 4, a water filtration and receiving mechanism, a drainage mechanism and a driving mechanism.

[0029] The collection channel is a channel that runs through the device body 1, and is mainly used to collect garbage and provide operating space for other components. The collection mechanism 3 is arranged at the front end of the collection channel, and the collection mechanism 3 moves between the front garbage area and the collection channel, so as to gather the garbage at the front end of the device and push it into the collection channel.

[0030] The gate mechanism 4 is arranged at the front end of the collection channel, and the gate mechanism 4 moves between the front end blocking position and the front end opening position. When the collection mechanism 3 performs a gathering action at the front end, the gate mechanism 4 closes the front end to prevent the garbage inside from escaping, and at the same time, it has a squeezing effect on the garbage during the closing action. When the collection mechanism 3 pushes the gathered garbage into the collection channel, the front end is opened.

[0031] The water filter receiving mechanism is located in the collection channel, and the garbage is filtered by the water filter receiving mechanism, and the filtered garbage is collected. At the same time, the collection mechanism 3 and the gate mechanism 4 can squeeze the garbage to improve the water filtering effect. The drainage mechanism is connected between the collection channel and the external environment, and is used to drain the excess water in the water filter receiving mechanism.

[0032] The device body 1 includes a pontoon frame 2, a cover plate and a bottom plate 8. The pontoon frames 2 are located on both sides, and the cover plate and the bottom plate 8 are connected between the pontoon frames 2 on both sides, so that a collecting channel with a rectangular cross-section is formed between the pontoon frames 2, the cover plate and the bottom plate 8. The cover plate includes a lower cover plate 5 and an upper cover plate 6, and a square tube profile 9 is fixedly connected between the lower cover plate 5 and the upper cover plate 6.

[0033] An integrated control cabinet 44 is installed at the rear of the cover plate, and the movement of each component is controlled by the control cabinet 44. The control cabinet 44 is the highest from the water surface and is an irregular prism. The front of the control cabinet 44 is an inclined surface, which is used to reduce wind resistance. There is a tail wing 45 at the rear of the control cabinet 44. Triangular water-breaking plates 57 are bonded to the front and rear ends of the pontoon frame 2 to reduce the resistance of traveling on the water surface. Handles 46 are provided at the four corners of the cover plate to facilitate the lifting of the device.

[0034] The collecting mechanism 3 includes a telescopic assembly and a baffle assembly. The telescopic assembly is symmetrically arranged on both sides of the pontoon frame 2, and the telescopic assembly is connected to the baffle assembly that opens and closes. The pontoon frame 2 is equipped with a telescopic collecting mechanism 3 through an upper slide 24 and a lower slide 25. The upper slide 24 is located on the top surface of the pontoon frame 2, and the lower slide 25 is located on the ground of the pontoon frame 2. The upper and lower slides are used to guide the baffle assembly to slide. A gear protection shell 55 is provided on the cover plate to protect and shield the telescopic assembly. The baffle assembly gathers and covers the garbage through opening and closing movements, and then the baffle assembly is retracted by the telescopic assembly to push the gathered garbage into the collection channel.

[0035] The telescopic assembly includes a transmission gear 18, a transmission rack 19, a transmission shaft 20, a bearing seat 21, a deep groove ball bearing 22, a reduction motor 23 and a collection motor seat 27. The reduction motor 23 is installed on the collection motor seat 27. The reduction motor 23 is connected to the transmission shaft 20 through a gear. The transmission shaft 20 is rotatably installed through the deep groove ball bearing 22 on the bearing seat 21. The bearing seat 21 is fixed on the cover plate. A transmission gear 18 is provided on the transmission shaft 20. The transmission gear 18 is meshed with the transmission rack 19 on the baffle assembly, and the transmission rack 19 is located in the upper slide 24. The transmission gear 18 is powered by the reduction motor 23, and the transmission rack 19 is driven forward and backward by the rotation of the transmission gear 18 to realize the telescopic effect of the baffle assembly. The reduction motor 23 drives the baffle assembly to perform linear motion inside the pontoon frame 2, and converts the rotational motion of the reduction motor 23 into the linear motion of the collection mechanism 3 inside the upper slide 24 and the lower slide 25.

[0036] The baffle assembly includes a telescopic baffle 10, a telescopic connecting rod 12, a waterproof electric cylinder 15 and a harpoon plate 29. The telescopic baffle 10 includes a rear baffle 101, a middle baffle 102 and a front baffle 103. The telescopic connecting rod 12 includes an inner connecting rod 122 and an outer connecting rod 121. The front end of the rear baffle 101 is hinged to the rear end of the middle baffle 102 through a hinge 11, and the front end of the middle baffle 102 is hinged to the rear end of the front baffle 103 through a hinge 11. The rear baffle 101 is provided with an electric cylinder fixing frame 16, on which a telescopic waterproof electric cylinder 15 is provided, which is hinged to the rear end of the outer connecting rod 121 through a connecting rod latch, the middle of the outer connecting rod 121 is hinged to the outer end of the inner connecting rod 122 through a connecting rod latch, the inner end of the inner connecting rod 122 is hinged to the telescopic connecting rod seat 13 at the rear end of the middle baffle 102 through a connecting rod latch, the front end of the outer connecting rod 121 is hinged to the rear end of the harpoon plate 29 through a connecting rod latch, and the front end of the harpoon plate 29 is fixed to the front baffle 103. A bent limiting plate 28 is fixed to the front end of the rear baffle 101, which limits the opening and closing angle of the middle baffle 102 to prevent excessive opening and closing.

[0037] When the garbage is collected, the waterproof electric cylinder 15 retracts, and under the action of the inner connecting rod 122 and the outer connecting rod 121, the middle baffle 102 and the front baffle 103 are driven to expand, forming a Y-shaped structure to collect the garbage. When the collection is completed, the waterproof electric cylinder 15 extends, and under the action of the inner connecting rod 122 and the outer connecting rod 121, the middle baffle 102 and the front baffle 103 are driven to retract, forming an L-shaped baffle structure on both sides to wrap up the garbage. At this time, the telescopic component moves to pull the baffle component back to achieve garbage collection.

[0038] The transmission rack 19 is segmented on the rear baffle 101 and the middle baffle 102. When the middle baffle 102 and the front baffle 103 are retracted together, the middle baffle 102 and the rear baffle 101 are continuously arranged in parallel, and the transmission gear can push the middle baffle 102 back into the collection channel to achieve overall retraction and squeeze the garbage at the same time.

[0039] The gate mechanism 4 includes a gate plate 30, a gate hinge 31, a slider connecting rod 32, a connecting seat 33, a gate rack 35, a gate gear 36, a gate slide rail 37, a gate connecting rod 38, a connecting rod seat pad 39, a gate slider 40, a slide rail stop steel 41, a gate motor 42 and a gate motor seat 43. The rear end of the gate plate 30 is hinged to one end of the gate connecting rod 38 through the gate hinge 31, and the other end of the gate connecting rod 38 is hinged to the cover plate. The gate plate 30 is provided with a gate rack 35 and a gate slide rail 37 arranged in parallel. The gate rack 35 is meshed with the gate gear 36 of the gate motor 42. The gate motor 42 is installed on the gate motor seat 43 on the cover plate. The gate slide rail 37 is slidably matched with the gate slider 40. The gate slider 40 is connected to the slider connecting rod 32. The slider connecting rod 32 is hinged to the connecting seat 33. The connecting seat 33 is arranged on the connecting rod seat pad 39 of the cover plate. The end of the gate plate 30 is fixed with a slide rail stop steel 41 to limit the gate slider 40 to prevent the gate slider 40 from slipping off.

[0040] The gate motor 42 provides power, and drives the gate plate 30 to move through the meshing transmission of the gate gear 36 and the gate rack 35. Since the front end of the gate plate 30 is limited by the sliding slider connecting rod 32 and the gate slider 40, and the rear end of the gate plate 30 is limited by the gate connecting rod 38, the gate plate 30 can move up and down. In the front port blocking position, the gate plate 30 is vertically closed at the front port, and in the front port opening position, the gate plate 30 is tilted at the top, which does not affect the collection of garbage. Driven by the gate motor 42, the gate plate 30 is driven to make a curved motion around the connecting seat 33. When the collection mechanism is extended for collection or retracted to the set position, the gate mechanism will then close the inlet and isolate the garbage inside the collection channel.

[0041] The water filtering and containing mechanism comprises a water filtering plate 50 and a garbage box 47. A tripod 48 is welded to the front end of the garbage box 47. The water filtering plate 50 is arranged on the tripod so that the water filtering plate 50 is tilted at the front of the garbage box 47. The garbage entering the channel is gradually lifted on the water filtering plate 50 under the effect of squeezing. The water flows downward from the holes on the water filtering plate, and the garbage keeps moving backward and upward until it enters the garbage box 47.

[0042] The garbage box 47 is detachably arranged at the rear end of the collection channel. When the garbage is full, the garbage box 47 is removed to uniformly process the garbage inside. A straight knob 56 is arranged at the rear of the garbage box 47. A hinged garbage box baffle 49 is arranged at the rear end of the collection channel through a hinge. The straight hole on the garbage box baffle 49 cooperates with the straight knob 56. When the garbage box 47 is loaded into the collection channel, the lock of the straight knob and the garbage box baffle 49 is used to fix the garbage box.

[0043] The drainage mechanism includes a water pump 53, which is fixed on a fixing frame 54 on the cover plate. The water pump 53 connects the trash box 47 with the external environment through a pipeline, and can drain the excess water in the trash box 47. The water pump 53 pumps out the water that enters the trash box 47 along with the trash, thereby reducing the total gravity of the device. There is a carrying handle at the rear of the trash box 47, and the device can be lifted out of the water by the carrying handle.

[0044] The driving mechanism includes a propeller 51 . The propellers 51 are installed on both sides of the pontoon frame 2 as thrusters to control the overall forward movement or steering. The propellers 51 are fixed to the pontoon frame 2 through propeller support plates 52 .

[0045] The working process of the present invention is as follows: when starting to work, the meshing of the transmission gear and the transmission rack pushes the collection mechanism out, the push of the waterproof electric cylinder makes the middle baffle and the front baffle open at the required angle, the device moves forward, and the garbage floating on the water surface enters the interior of the collection mechanism. When enough garbage is collected, the push of the waterproof electric cylinder makes the middle baffle and the front baffle close, and the rotation of the reduction motor makes the transmission gear drive the transmission rack to retract back into the device through the transmission shaft. The garbage floating on the water surface is then pushed onto the water filter plate, and when the collection mechanism extends to collect garbage for the second time, the gate plate on the cover plate is lowered through the transmission of the gate gear and the gate rack, and the garbage is locked in the device. When the collection mechanism is full of garbage and retracts back into the device, the gate plate is opened, and by borrowing the power of the collection mechanism, the garbage collected for the second time squeezes the garbage on the water filter plate, and squeezes the garbage on the water filter plate into the garbage box connected to the water filter plate, thereby achieving the effect of cyclic contraction and cyclic squeezing of garbage. The holes on the filter plate can filter most of the water brought by the garbage on the water surface. There is also a water pump on the top of the garbage box, which regularly extracts excess water from the garbage box, thereby reducing the weight of the entire device. When the garbage box is detected to be full of garbage, the device automatically returns to the home position, and the garbage box baffle is opened by turning the straight knob, and the garbage box in the collector is pulled out to remove the garbage.

In the scheme of the present invention, each optional example can be arbitrarily combined with any other basic examples and optional examples.
