[0069] Example 1:

[0070] like Figures 1 to 6As shown, the utility model provides a river patrol device with an image recognition function, comprising: a river patrol hull 1 and a cleaning rod 2 arranged on the river patrol hull 1 for blocking garbage and guiding the garbage to the middle, a suction pump 3 cooperating with the cleaning rod 2 for sucking up the garbage guided by the cleaning rod 2, a suction pipe 4 arranged on the suction end of the suction pump 3, and an image acquisition device 5 arranged on the river patrol hull 1 for acquiring and transmitting images of the river channel, wherein the image acquisition device 5 is a camera with a transmission function.

One side of 601 is used to drive the motor 607 of the rotating shaft 1 603 to rotate. The output end of the motor 607 is arranged at one end of the rotating shaft 1 603. The hopper 601 is located below the suction pump 3 and is used to receive the garbage sucked up by the suction pump 3. Turning on the suction pump 3 can make it use the suction pipe 4 to suck the garbage into the hopper 601. During the process, the motor 607 can be turned on to drive the rotating shaft 1 603 and the rotating shaft 2 604 to rotate. Under the action of the rotating shaft 1 603 and the rotating shaft 2 604, they can respectively drive the two crushing rollers 605 to rotate, and then crush the garbage transported to the hopper 601.

[0073] Example 2:

[0074] On the basis of Example 1, in order to separate the water in the garbage and reduce the weight of the garbage, a dehydration structure for dehydrating the crushed garbage is arranged on the crushing structure. The dehydration structure is used in conjunction with the crushing structure. The dehydration structure includes a feeding component for conveying the garbage and an extrusion component for squeezing the garbage to dehydrate it.

[0075] Among them, the feeding assembly includes a connecting shaft 7 rotatably mounted on the inner wall of the support box 6, a transmission roller 701 arranged on the connecting shaft 7, a conveyor belt 702 driven by the transmission roller 701, a support roller 703 rotatably mounted on the inner wall of the support box 6 for supporting the conveyor belt 702, the support roller 703 is in contact with the conveyor belt 702, and a linkage assembly is arranged on the connecting shaft 7 for driving the connecting shaft 7 to rotate. The conveyor belt 702 is located below the crushing roller 605 and is used to receive the garbage crushed by the crushing roller 605. A number of mesh holes for water leakage are provided on the conveyor belt 702. The crushed garbage will fall onto the conveyor belt 702 in the support box 6, and can drive the conveyor belt 702 to move in a circle under the continuous rotation of the rotating shaft 2 604, so that the conveyor belt 702 can transport the garbage.

[0076] Specifically, the linkage assembly includes a transmission wheel 1 704 arranged at one end of the rotating shaft 2 604 for rotating with the rotating shaft 2 604, a transmission belt 705 installed on the transmission wheel 1 704, and a transmission wheel 2 706 arranged at one end of the connecting shaft 7. The transmission wheel 2 706 is installed on the transmission belt 705 and can drive the transmission wheel 1 704 to rotate under the continuous rotation of the rotating shaft 2 604. The rotating transmission wheel 1 704 can drive the transmission wheel 2 706 to rotate by cooperating with the transmission belt 705, so that the transmission wheel 2 706 drives the connecting shaft 7 to rotate.

[0077] Among them, the feeding assembly also includes a drain pipe 707 arranged on one side of the support box 6 for discharging water in the support box 6. The drain pipe 707 is connected to the support box 6, and the inner wall of the support box 6 is inclined to guide the flow direction of water. The water in the garbage can flow into the inner wall of the support box 6 through the leakage holes on the conveyor belt 702, and then be guided to the drain pipe 707 through the inclined inner wall of the support box 6, and finally be discharged through the drain pipe 707.

[0078] Among them, the squeezing assembly includes an L-shaped support plate 8 arranged on the support box 6, a guide slide 801 slidably installed on the L-shaped support plate 8, a roller frame 802 arranged at one end of the guide slide 801, a pressure wheel 803 rotatably installed on the roller frame 802 for squeezing garbage, a baffle 804 arranged at one end of the guide slide 801 for preventing the guide slide 801 from loosening, a spring 805 sleeved on the guide slide 801, and two ends of the spring 805 are respectively arranged on the L-shaped support plate 8 and the roller frame 802, for driving the movement of the roller frame 802 for reset. In the process of transporting garbage, the garbage will squeeze the pressure wheel 803 and move it, and the pressure wheel 803 will compress the spring 805 through the roller frame 802. At the same time, the compression force of the spring 805 can act on the roller frame 802, thereby increasing the force of the pressure wheel 803 pressing against the garbage, thereby squeezing out the moisture in the garbage.

[0079] Example 3:

[0080] On the basis of Example 2, in order to make the crushed garbage more compact during storage, save storage space, and thus be able to load more garbage, a recycling structure for storing the crushed garbage is arranged on the river patrol boat 1, and the recycling structure corresponds to the crushing structure.

[0081] Among them, the recycling structure includes a storage box 9 arranged on the river patrol ship 1, and a compaction structure arranged on the storage box 9 for compacting the garbage in the storage box 9. The storage box 9 corresponds to the discharge port of the supporting box body 6 and is used to receive the garbage transported out of the supporting box body 6. The garbage after crushing and dehydration will be transported to the storage box 9 for storage.

[0082] Specifically, the compaction structure includes a U-shaped frame 901 arranged on the storage box 9, a multi-stage electric push rod 902 arranged above the U-shaped frame 901, the output end of the multi-stage electric push rod 902 passes through the U-shaped frame 901, and an extrusion plate 903 arranged on the output end of the multi-stage electric push rod 902. When the garbage in the storage box 9 is almost full, the transportation can be suspended first, and then the multi-stage electric push rod 902 can be turned on to drive the extrusion plate 903 to descend and press on the garbage in the storage box 9 to compact the garbage.

[0083] Working principle: When the patrol boat 1 is traveling on the water, it can block the garbage through the two cleaning rods 2 and guide the garbage to the middle position of the two cleaning rods 2. At this time, the suction pump 3 is turned on to use the suction pipe 4 to suck the garbage into the hopper 601. By setting the image acquisition device 5, the cleaning status of the river can be checked for easy supervision. During the process, the motor 607 can be turned on, and the output end of the motor 607 can drive the shaft 1 603 to rotate. The rotating shaft 1 603 can drive one of the gears 606 to rotate. Through the mutual engagement of the two gears 606, one of the gears 606 is engaged. When the wheel 606 rotates, it can drive another gear 606 to rotate in the direction of approaching each other, thereby causing the other gear 606 to drive the second shaft 604 to rotate. Under the action of the first shaft 603 and the second shaft 604, the two crushing rollers 605 can be driven to rotate respectively, thereby crushing the garbage transported to the hopper 601. The crushed garbage will fall onto the conveyor belt 702 in the supporting box 6, and the continuous rotation of the second shaft 604 can drive the transmission wheel 1 704 to rotate. The rotating transmission wheel 1 704 can drive the transmission wheel 2 706 to rotate through the transmission cooperation with the transmission belt 705. The transmission wheel 2 706 drives the connecting shaft 7 to rotate, and the transmission roller 701 cooperates with the conveyor belt 702, so that the rotating connecting shaft 7 can drive the conveyor belt 702 to move in a circular motion, so that the conveyor belt 702 can transport the garbage. During the transportation process, the garbage will squeeze the pressure wheel 803 and move it, and the pressure wheel 803 will drive the roller frame 802 to move. The moving roller frame 802 will drive the guide slide bar 801 to slide on the L-shaped support plate 8 and compress the spring 805. At the same time, the compression force of the spring 805 can act on the roller frame 802, increasing the force of the pressure wheel 803 pressing the garbage, thereby It can squeeze out the moisture in the garbage, and the squeezed water can flow into the inner wall of the support box 6 through the leakage holes on the conveyor belt 702, and then be guided to the drain pipe 707 through the inclined inner wall of the support box 6, and finally be discharged through the drain pipe 707. The garbage after crushing and dehydration will be transported to the storage box 9 for storage. When the garbage in the storage box 9 is almost full, the transportation can be suspended first, and then the multi-stage electric push rod 902 can be turned on to drive the extrusion plate 903 to descend at its output end. The descending extrusion plate 903 can be pressed on the garbage in the storage box 9 to compact the garbage, increase the storage space in the storage box 9, and enable it to store more garbage.

[0084] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
