Description

Technical Field

[0001] This utility model relates to the field of environmental protection and cleaning equipment technology, specifically a small unmanned water surface cleaning device. Background Technology

[0002] Currently, with social development and economic growth, environmental pollution problems are becoming increasingly prominent, with water pollution being particularly alarming. Water pollution includes water body pollution and surface garbage pollution. Due to the lack of environmental awareness among the public and businesses, floating waste is carelessly discarded in lakes and rivers, leading to a large accumulation of floating debris and causing serious pollution to the water. Therefore, in order to protect the water environment, it is necessary to collect and dispose of floating debris in rivers and lakes in a timely manner.

[0003] Existing technologies also include some waterless surface cleaning vessels, but these unmanned surface cleaning vessels have a relatively fixed retrieval mechanism, resulting in a small retrieval range. They need to move the vessel back and forth to expand the retrieval range, which leads to low retrieval efficiency. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a small, unmanned water surface cleaning device to solve the technical problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a small unmanned water surface cleaning device, comprising a hull and a tractor. The tractor is equipped with a vector propeller. A first fixed rod and a second fixed rod are connected to the top of the tractor. Clamps are installed on the top of the hull and one side of the tractor, and a net is bolted between the two clamps. Several hanging rings are installed on the top of the net. Two sets of first and second winding assemblies are respectively provided on both sides of the top of the hull. The first winding assembly includes a mounting frame, inside which a first winding wheel is installed. A motor is installed on the outer surface of the first winding wheel. A first traction rope is connected inside the first winding wheel, and the other end of the first traction rope is connected to the first fixed rod. The second winding assembly includes a winding box, inside which a coil spring and a rotating rod are installed. One end of the coil spring is connected to the rotating rod. A second winding wheel is installed on the outer surface of the rotating rod, and a second traction rope is connected to the outer surface of the second winding wheel. The other end of the second traction rope is connected to the second fixed rod.

[0006] Furthermore, a control box is installed on one side of the top of the hull, and the control box contains a central controller, a lithium battery pack, a signal converter, and a router.

[0007] By adopting the above technical solution, the router integrates a 5G communication module. The central controller is connected to the cloud platform through the 5G network. The signal converter receives and converts the signal commands, which are then processed by the central controller, so that each component can make corresponding actions (such as controlling the vector propeller to move forward or turn, controlling the operation of the salvage mechanism, and controlling the motor to start or stop). Therefore, there is no need for staff to go on the ship to operate the device. The device can be operated remotely from the shore through the cloud platform.

[0008] Furthermore, a collection frame is placed in the middle of the top of the hull, and the collection frame is hollowed out. A salvage mechanism is installed inside the hull.

[0009] By adopting the above technical solution, the retrieval mechanism is an existing technology. When the garbage comes into contact with the conveyor belt, the output end of the servo motor drives the rotating roller to rotate, so that the baffle on the conveyor belt scoops up the garbage from the water surface. Driven by the conveyor belt, the garbage is transferred to the collection box for centralized storage. By making the collection box hollow, it is easy to drain the water from the garbage into the collection box.

[0010] Furthermore, both the first and second traction ropes are made of steel wire.

[0011] By adopting the above technical solution, the wire rope is made of multiple strands of high-strength steel wire, with a tensile strength far exceeding that of ordinary fiber ropes or chains. Driven by the propeller, two sets of traction boats pull the first traction rope through the first fixed rod. At the same time, two motors rotate in coordination, causing the first winding wheel to release the first traction rope. At this time, the traction boat moves forward. Under the pull of the traction boat, the second fixed rod pulls the second traction rope. During the extension of the two sets of second traction ropes, the second winding wheel is driven to rotate, causing the rotating rod to drive the coil spring to compress. At the same time, under the action of the clamping plate, the interception net is extended, thereby increasing the interception range of the device for garbage. By intercepting the garbage through the two sets of interception nets, the garbage is concentrated between the two sets of interception nets, which facilitates the subsequent retrieval by the retrieval mechanism, thereby improving the retrieval efficiency.

[0012] Furthermore, the traction vessel is provided in two sets, and the two sets of traction vessels are symmetrically distributed.

[0013] By adopting the above technical solution, the vector propeller propeller is powered by a diesel internal combustion engine. Driven by the vector propeller propeller, the traction vessel can move, hover, and turn. While the traction vessel pulls the hull, it can also extend the interception net, thereby expanding the salvage range of the device and improving its practicality.

[0014] Furthermore, several of the hanging rings are slidably connected to the first traction rope.

[0015] By adopting the above technical solution, several hanging rings are evenly distributed on the top of the interception net. The hanging rings work together with the second traction rope to support the interception net, preventing the middle part of the interception net from collapsing and creating gaps after it is extended, which would cause the garbage to leave through the gaps and affect the salvage effect.

[0016] Furthermore, the interception net is made of PVC coated fabric.

[0017] By adopting the above technical solution, the interception net made of PVC coated cloth is durable and easy to maintain. When the device is operating in a confined space, the two motors drive the first winding wheel to rotate, so that the first winding wheel winds up the first traction rope, thereby pulling the towing boat back to its original position. At this time, under the action of the coil spring, the rotating rod drives the second winding wheel to rotate, thereby winding up the second traction rope. At the same time, under the pressure of the towing boat, the interception net is contracted (at this time, the state of the interception net is similar to the state of the curtain after it is contracted). The towing boat and the hull are combined into a whole, reducing the overall size of the device, thus facilitating the device to operate in confined spaces.

[0018] Furthermore, a protective box is connected to one side of the mounting bracket, and the motor is located inside the protective box.

[0019] By adopting the above technical solution, the motor is shielded by a protective box, preventing the motor from being directly exposed to the outside, which could lead to water damage and extend the motor's service life.

[0020] Furthermore, a solar panel is installed on the top of the control box, and the solar panel is electrically connected to the lithium battery pack.

[0021] By adopting the above technical solution, solar energy is converted into electrical energy through solar panels, and then stored in a lithium battery pack after conversion by an inverter to power components such as the central controller, thereby extending the device's operating time.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model, by setting up a traction rope and an interception net, allows two sets of traction boats to pull the first traction rope through the first fixed rod under the propeller thrust. At the same time, two motors rotate in coordination, causing the first winding wheel to release the first traction rope. At this time, the traction boats move forward. Under the pull of the traction boats, the second fixed rod pulls the second traction rope. During the extension of the two sets of second traction ropes, the second winding wheel is driven to rotate, causing the rotating rod to drive the coil spring to compress. At the same time, under the drive of the clamping plate, the interception net is extended, thereby increasing the interception range of the device for garbage. By intercepting garbage through two sets of interception nets, the garbage is concentrated between the two sets of interception nets, which facilitates the subsequent retrieval by the retrieval mechanism, thereby improving the retrieval efficiency.

[0024] 2. This utility model has several hanging rings, which work together with the second traction rope to support the interception net, preventing the middle part of the interception net from collapsing and creating gaps after it is extended, which would cause the garbage to leave through the gaps and affect the salvage effect.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] Example 1: A small, unmanned water surface cleaning device, such as Figures 1-5As shown, the system includes a hull 1 and a tractor 2. The tractor 2 is equipped with a vector propeller 10. A first fixed rod 606 and a second fixed rod 706 are connected to the top of the tractor 2. Clamping plates 8 are installed on the top of the hull 1 and one side of the tractor 2, and a netting 16 is bolted between the two clamping plates 8. Several hanging rings 9 are installed on the top of the netting 16. Two sets of first winding assemblies 6 and second winding assemblies 7 are respectively located on the top sides of the hull 1. The first winding assembly 6 includes a mounting frame 601, inside which a first winding wheel 604 is installed. A motor 603 is installed on the outer surface of the first winding wheel 604. A first traction rope 605 is connected inside the first winding wheel 604, and the other end of the first traction rope 605 is connected to the first fixed rod 606. The second winding assembly 7 includes a winding box 701, inside which a coil spring 702 and a rotating rod 703 are installed. The end is connected to the rotating rod 703. The outer surface of the rotating rod 703 is equipped with a second winding wheel 704, and the outer surface of the second winding wheel 704 is connected to a second traction rope 705. The other end of the second traction rope 705 is connected to a second fixed rod 706. A control box 3 is installed on one side of the top of the hull 1. The control box 3 contains a central controller 12, a lithium battery pack 11, a signal converter 13, and a router 14. The router 14 integrates a 5G communication module. The central controller 12 is connected to the cloud platform through a 5G network. The signal converter 13 receives and converts the signal commands. After processing by the central controller 12, each component makes corresponding actions (such as controlling the vector propeller thruster 10 to move forward or turn, controlling the operation of the salvage mechanism 4, and controlling the motor 603 to start or stop). Therefore, it is not necessary for staff to board the ship to operate the device. The device can be operated remotely from the shore through the cloud platform.

[0034] See Figure 1 and Figure 2 In the above embodiment, a collection frame 5 is placed in the middle of the top of the hull 1, and the collection frame 5 is hollow. A retrieval mechanism 4 is installed inside the hull 1. The retrieval mechanism 4 is the prior art. When the garbage comes into contact with the conveyor belt, the output end of the servo motor 603 drives the rotating roller to rotate, so that the baffle on the conveyor belt picks up the garbage from the water surface. Under the drive of the conveyor belt, the garbage is transferred to the collection frame 5. The garbage is centrally stored in the collection frame 5. By making the collection frame 5 hollow, it is convenient to drain the water from the garbage into the collection frame 5.

[0035] See Figures 1-5In the above embodiment, both the first traction rope 605 and the second traction rope 705 are made of steel wire. The steel wire rope is made of multiple strands of high-strength steel wire twisted together, and its tensile strength is far greater than that of ordinary fiber ropes or chains. Under the propeller thrust, the two sets of traction boats 2 pull the first traction rope 605 through the first fixed rod 606. At the same time, the two motors 603 rotate in coordination, causing the first winding wheel 604 to release the first traction rope 605. At this time, the traction boat 2 moves forward. Under the pull of the traction boat 2, the second fixed rod 706 pulls the second traction rope 705. During the extension of the two sets of second traction ropes 705, the second winding wheel 704 is driven to rotate, causing the rotating rod 703 to drive the coil spring 702 to compress. At the same time, under the drive of the clamping plate 8, the interception net 16 is extended, thereby increasing the interception range of the device for garbage. The garbage is intercepted by the two sets of interception nets 16 and concentrated between the two sets of interception nets 16, which facilitates the subsequent retrieval by the retrieval mechanism 4, thereby improving the retrieval efficiency.

[0036] See Figure 1 and Figure 2 In the above embodiment, there are two sets of traction vessels 2, and the two sets of traction vessels 2 are symmetrically distributed. The vector propeller propeller 10 is powered by a diesel internal combustion engine. Driven by the vector propeller propeller 10, the traction vessel 2 can move, hover and turn. While the traction vessel 2 pulls the hull 1 to move, it can also extend the interception net 16, thereby expanding the salvage range of the device and improving the practicality of the device.

[0037] See Figure 1 , Figure 2 and Figure 5 In the above embodiment, several hanging rings 9 are slidably connected to the first traction rope 605. Several hanging rings 9 are equidistantly distributed on the top of the interception net 16. The hanging rings 9 cooperate with the second traction rope 705 to support the interception net 16, so as to prevent the middle position of the interception net 16 from collapsing and creating a gap after it is extended, which would cause the garbage to leave through the gap and affect the salvage effect.

[0038] See Figure 1 and Figure 2 In the above embodiment, the interception net 16 is made of PVC coated fabric. The interception net 16 made of PVC coated fabric is durable and easy to maintain. When the device is operating in a confined space, the two motors 603 simultaneously drive the first winding wheel 604 to rotate, so that the first winding wheel 604 winds up the first traction rope 605, thereby pulling the towing boat 2 back to its original position. At this time, under the drive of the coil spring 702, the rotating rod 703 drives the second winding wheel 704 to rotate, thereby winding up the second traction rope 705. At the same time, under the compression of the towing boat 2, the interception net 16 is contracted (at this time, the state of the interception net 16 is similar to the state after the curtain is contracted). The towing boat 2 and the hull 1 are combined into a whole, reducing the overall size of the device, thereby facilitating the device to operate in confined spaces.

[0039] See Figure 1 , Figure 2 and Figure 4 In the above embodiment, a protective box 602 is connected to one side of the mounting bracket 601, and the motor 603 is located inside the protective box 602. The protective box 602 shields the motor 603, preventing the motor 603 from being directly exposed to the outside, which would cause water to enter and damage the motor 603, thereby extending the service life of the motor 603.

[0040] Example 2: To improve the operating time of the device, Example 2 is an improvement on Example 1. (See attached document.) Figure 1 and Figure 2 A solar panel 15 is installed on the top of the control box 3, and the solar panel 15 is electrically connected to the lithium battery pack 11. The solar panel 15 converts light energy into electrical energy, which is then converted by the inverter and stored in the lithium battery pack 11 to power components such as the central controller 12, thereby extending the device's operating time.

[0041] The implementation principle of this utility model is as follows: During salvage operations, staff send instructions via a remote control cloud platform. The signal converter 13 receives and converts these instructions, which are then processed by the central processing unit, causing each component to perform corresponding actions. Under the control of the central processing unit, the vector propeller thruster 10 is activated to propel the traction vessel 2 forward. Pulled by the first traction rope 605, the vessel hull 1 moves. At this time, the salvage mechanism 4 is activated to collect surface debris into the collection frame 5. When it is necessary to expand the salvage area, both motors 603 are simultaneously activated and reversed. The outputs of the two motors 603 drive the first winding wheel 604 to rotate, causing the first winding wheel 604 to release the first traction rope 605. This allows the vector propeller thruster 10 to propel the traction vessel 2 forward. Under the pull of the traction vessel 2, the second fixed rod 706 pulls the second traction rope 705. During the extension of the two sets of second traction ropes 705, the second winding wheel 704 rotates, causing the rotating rod 703 to drive the coil spring 702 to rotate and compress it. At the same time, under the action of the clamping plate 8, the interception net 16 extends, concentrating the garbage between the two sets of interception nets 16, which facilitates the subsequent retrieval by the retrieval mechanism 4. When returning after retrieval, the vector propeller thruster 10 is controlled to make the traction boat 2 slowly retreat. At the same time, the motor 603 is started to rotate forward, causing the first winding wheel 604 to wind up the first traction rope 605, driving the traction boat 2 back to its original position. At the same time, under the action of the coil spring 702, the rotating rod 703 drives the second winding wheel 704 to rotate, thereby winding up the first traction rope 605. At this time, during the process of the traction boat 2 returning to its original position, the traction boat 2 squeezes and compresses the interception net 16. After completion, the control device returns to the shore to process the garbage in the collection box 5.
