[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] Example 1: like Figure 1 - Figure 8 As shown in the figure, this embodiment proposes a river weed cleaning device, including a hull 1, the hull 1 is provided with a collection box 7 and a power mechanism, the power mechanism can provide forward power to the hull.

[0024] The hull 1 is also equipped with a control mechanism, which contains a microcontroller for controlling the water weed removal device in this river channel.

[0025] Specifically, a single-chip microcomputer is an integrated circuit chip, a mature product on the market. It is a small but complete microcomputer system that integrates a central processing unit (CPU) with data processing capabilities, random access memory (RAM), read-only memory (ROM), various I / O ports and interrupt systems, timers / counters, and other functions (and may also include display driver circuits, pulse width modulation circuits, analog multiplexers, A / D converters, etc.) onto a single silicon chip using very large-scale integrated circuit technology. It features small size, high integration, simple structure, reliable performance, and modular application, and is widely used in the field of industrial control through corresponding control programs.

[0026] A bracket 2 is fixed at the bow of the hull 1. The bracket 2 forms a certain angle with the upper surface of the hull 1. The cleaning roller 6 is rotatably connected to the side of the bracket 2 away from the bow. A conveyor belt 8 is rotatably connected to the bracket 2. The conveyor belt 8 is located between the collection box 7 and the cleaning roller 6. The conveyor belt 8 can cooperate with the cleaning roller 6.

[0027] Specifically, the conveyor belt 8 can be made of metal mesh or other materials. The holes in the metal mesh allow excess water to drain out during the transfer of aquatic plants into the collection box 7, preventing excessive water in the collection box 7 from increasing the weight of the hull 1.

[0028] Furthermore, an electric slip ring 11 is rotatably connected to one side of the cleaning roller 6, the fixed end of the electric slip ring 11 is fixedly connected to the bracket 2, and the electric slip ring 11 is electrically connected to the control mechanism.

[0029] Specifically, the slip ring 11 is a mature product on the market. For a more specific option, you can choose the MZ056 series rotor flange conductive slip ring from Shenzhen MOFLON Technology Co., Ltd. This type of slip ring can achieve more channels and larger current, and can be used to customize various sensitive signals or encoder signals to achieve smooth power supply and signal transmission. It is widely used in industrial machine processing centers, rotary tables, heavy equipment towers, process control equipment, rotary sensors, robots, exhibition / display equipment, medical equipment, etc.

[0030] Furthermore, one set of rollers on the conveyor belt 8 is rotatably connected to a first motor 3. The first motor 3 is fixedly connected to the bracket 2. The first motor 3 and the cleaning roller 6 are driven by the transmission belt 10. The first motor 3 is on the same side as the electric slip ring 11. The first motor 3 is electrically connected to the control mechanism.

[0031] Furthermore, a protective cover 9 is provided on the outside of the first motor 3, the transmission belt 10, and the electric slip ring 11, for protection in high humidity environments and to prevent damage caused by the intrusion of aquatic plants and other debris.

[0032] Specifically, the transmission belt 10 can be a synchronous belt drive or can be replaced with other transmission methods such as a chain, which is a mature mechanical design transmission method.

[0033] The cleaning roller 6 has several sets of short rods 22 evenly distributed on its outer circumference. The short rods 22 are used by the cleaning roller 6 to better gather the water plants in the river. The cleaning roller 6 has a groove at a suitable position. A lead screw 15 is rotatably connected in the groove. The cutter 14 is threadedly connected to the lead screw 15. An auxiliary guide rod is also fixed in the groove. The cutter slides on the auxiliary guide rod. One end of the lead screw 15 extends out of the groove. A gear 13 is fixedly connected to the extended end of the lead screw 15. A second motor 12 is fixedly connected at a suitable position in the cleaning roller 6. An auxiliary gear is set on the shaft of the second motor 12. The auxiliary gear meshes with the gear 13. The second motor 12 is electrically connected to the control mechanism.

[0034] Specifically, when the second motor 12 is working, it drives the lead screw 15 to rotate through the gear 13. Under the action of the auxiliary guide rod, the cutter 14 slides in the groove towards the other end of the cleaning roller 6, thereby cutting the water plants wrapped on the cleaning roller 6. With the cooperation of the conveyor belt 8, the water plants on the cleaning roller 6 are transferred to the collection box 7. The control mechanism causes the cutter 14 to return to the starting position after moving to the other end of the cleaning roller 6, thereby achieving secondary cleaning and avoiding residue.

[0035] Furthermore, the cutter 14 has blades 20 fixed on both the left and right sides, and a wedge-shaped surface 21 is provided on one side of the cutter 14, which can cooperate with the slide groove.

[0036] Specifically, as the cutter 14 slides toward the other end of the cleaning roller 6, it removes impurities from the groove through the wedge-shaped surface 21. The blades 20 on both sides enable the cutter 14 to smoothly cut the aquatic plants during its sliding in both directions.

[0037] Furthermore, protective shells are provided at the initial position of the cutter 14 and at the other end of the cleaning roller 6. The protective shell at the initial position is used to protect the cutter 14 from damage during the rotation of the cleaning roller 6, and the protective shell of the cleaning roller 6 is used to assist the cutter 14 in smoothly cutting the tangled aquatic plants.

[0038] Furthermore, a movable block 17 is slidably connected to a suitable position of the cleaning roller 6 via a spring. The moving direction of the movable block 17 is perpendicular to the axis of the cleaning roller 6. A second switch 18 that cooperates with the movable block 17 is fixed to the cleaning roller 6. The second switch 18 is electrically connected to the control mechanism.

[0039] Specifically, when too much aquatic plant is entangled on the cleaning roller 6, it will become increasingly tighter due to the rotation of the cleaning roller 6 and the constraint of the aquatic plant by other aquatic plants. This forces the movable block 17 to compress the spring and move towards the axis of the cleaning roller 6, causing the second switch 18 to operate. After the second switch 18 sends a signal to the control mechanism, the control mechanism controls the rotation of the second motor 12 to smoothly achieve the working sliding and return of the cutter 14 to its initial position. After the aquatic plant on the cleaning roller 6 is cut, the constraint of the movable block 17 disappears and resets under the action of the spring, and the second switch 18 resets.

[0040] Furthermore, to better remove the water plants entangled on the cleaning roller 6, an electric push rod 4 is fixed at a suitable position on the bracket 2. The electric push rod 4 is electrically connected to the control mechanism. A cleaning plate 5 is fixedly connected to the working shaft end of the electric push rod 4. To ensure the smooth operation of the cleaning plate 5 and to prevent excessive water plants on the cleaning plate 5 from damaging the working shaft of the electric push rod 4, an auxiliary slide rod is also fixedly connected to the fixed connection between the working shaft end of the electric push rod 4 and the cleaning plate 5. The auxiliary slide rod can slide through the fixed seat of the electric push rod 4. Several sets of notches are provided at the end of the cleaning plate 5 away from the electric push rod 4. The notches can cooperate with the short rods 22 on the cleaning roller 6 so that the short rods 22 can pass through the notches when the cleaning roller 6 rotates.

[0041] Specifically, when the second switch 18 is working, the control mechanism starts the electric push rod 4 after a delay according to the signal of the second switch 18, so that when the cleaning plate 5 is working, the water plants cut on the cleaning roller 6 are temporarily transferred to the cleaning plate 5, or are removed from the cleaning roller 6 by the cleaning plate 5 and fall into the water to wait for recollection.

[0042] Furthermore, to better control the start of the electric push rod 4 and avoid the cutter 14 moving unpredictably or getting stuck midway due to excessive aquatic plants, the electric push rod 4 will cause the cleaning plate 5 to work after the predetermined time has elapsed, which could damage the device. If the cutter 14 slides smoothly to the opposite side of the initial position, it will return to the initial position more smoothly, which is also beneficial for time control. A first switch 16 is also fixed at the bottom of the groove on the cleaning roller 6. The first switch 16 is electrically connected to the control mechanism. The first switch 16 is located on the side away from the gear 13. The first switch 16 can cooperate with the cutter 14. When the first switch 16 is working, it can delay the work of the cleaning plate 5 and cancel the start of the electric push rod 4 by the signal of the second switch 18, and instead control it by the signal of the first switch 16.

[0043] Furthermore, the control mechanism starts timing when the electric push rod 4 is started, based on the rotation speed of the cleaning roller 6, to ensure that the engagement time between the cleaning plate 5 and the cleaning roller 6 is not less than one rotation cycle of the cleaning roller 6. After the timing ends, the control mechanism resets the electric push rod 4.

[0044] Specifically, when the cutter 14 moves smoothly to the position of the first switch 16, the bottom surface of the cutter 14 causes the first switch 16 to work. The first switch 16 sends a signal to the control mechanism. According to the signal from the first switch 16, the control mechanism delays the operation of the electric push rod 4. After ensuring that the cutter 14 returns to the initial position, the cleaning plate 5 moves to the working area of ​​the cleaning roller 6. After the cleaning plate 5 and the cleaning roller 6 rotate for a certain period of time, the control mechanism resets the electric push rod 4.

[0045] Specifically, the first switch 16, the second motor 12, and the second switch 18 are all electrically connected to the control mechanism via an electric slip ring 11.

[0046] Specifically, both the first switch 16 and the second switch 18 are push-button spring switches, mature products on the market. Push-button spring switches typically consist of a push button, a spring, a mounting base, and conductive contacts. The push button is usually made of plastic or metal, possessing a certain degree of pressing performance and mechanical strength. The spring's function is to allow the button to automatically return to its original position and ensure the elasticity of the press. The mounting base is used to fix the button and spring, ensuring their positions do not change. The conductive contacts are the key part connecting the circuit; pressing the button connects or disconnects the circuit through the contacts, thus realizing the switch function.

[0047] A cleaning rod 19 is also fixed at a suitable position on the bracket 2. The cleaning rod 19 is fixed with a brush that cooperates with the cleaning plate 5. When the cleaning plate 5 is reset, the brush can clean the water plants on the cleaning plate 5 onto the conveyor belt 8 below.

[0048] It should be noted that both the first motor 3 and the second motor 12 are mature products on the market, with the second motor 12 having rotation functions in both forward and reverse directions.

[0049] It should be noted that this device is also equipped with a power supply to provide electrical support for the device. This is a mature solution in the market and is not shown in the diagram.

[0050] The working principle and usage process of this utility model.

[0051] S1: Move hull 1 to the river channel where aquatic plants need to be cleared, and adjust the forward speed of hull 1 according to the distribution of aquatic plants.

[0052] S2: Start the first motor 3 to make the conveyor belt 8 and the cleaning roller 6 rotate. The water plants are transferred to the conveyor belt 8 and then to the collection box 7 by the short rod 22 on the cleaning roller 6.

[0053] S3: When water plants are wrapped around the cleaning roller 6, the movable block 17 activates the second switch 18, and the control mechanism starts the second motor 12. By controlling the forward and reverse rotation of the second motor 12, the cutter 14 completes the reciprocating movement on the cleaning roller 6, cuts the water plants wrapped around the cleaning roller 6, and transfers them to the collection box 7 with the help of the conveyor belt 8. After the water plants wrapped around the cleaning roller 6 are cut, the movable block 7 resets, and the second switch 18 resets.

[0054] S4: In step S3, when the cutter 14 moves to the opposite side of the initial position, the first switch 16 is activated. According to the signal from the first switch 16, the control mechanism, through the delay timing function of the control mechanism, activates the electric push rod 4 after the cutter 14 successfully returns to the initial position. At the same time, the first switch 16 is reset after the cutter 14 leaves, so that the cleaning plate 5 and the cleaning roller 6 cooperate to remove the water plants wrapped on the cleaning roller 6.

[0055] S5: In step S4, when the electric push rod 4 is working, the control mechanism times the working time of the electric push rod 4. During the timing process, it is ensured that the cooperation between the cleaning plate 5 and the cleaning roller 6 is at least one rotation cycle of the cleaning roller 6. After the timing ends, the control mechanism resets the electric push rod 4. During the reset process of the cleaning plate 5, with the help of the brush of the cleaning rod 19, the water plants on the cleaning plate 5 are cleaned onto the conveyor belt 8 below.
