Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of underwater debris cleaning equipment, and in particular to a portable underwater debris cleaner. Background Technology
[0002] Underwater debris removal has always been a challenge in aquatic environments. With increasing environmental awareness and greater emphasis on aquatic ecosystems, underwater debris removal has become increasingly important. Traditional methods, such as manual diving, are not only inefficient but also pose safety risks, requiring highly skilled and physically fit divers. While large-scale underwater debris removal equipment offers strong cleaning capabilities, it is often bulky and complex, making it unsuitable for operation in small bodies of water or confined spaces. Furthermore, the equipment is expensive to manufacture and maintain. In scenarios such as parks, lakes, and small rivers, there is a need for a user-friendly and portable underwater debris removal device that can quickly and effectively remove debris and improve the aquatic environment. However, existing equipment falls short of these needs, making the development of a portable underwater debris remover an urgent priority. Utility Model Content
[0003] The main purpose of this invention is to provide a portable underwater debris cleaner that can effectively solve the problems in the background art.

[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. High cleaning efficiency: The propeller is driven by a motor to generate a large water flow, which blows up the lighter sediment at the bottom of the water, making it easier to collect. Compared with traditional manual dredging methods, the cleaning efficiency is greatly improved.
[0019] 2. Protection of the propulsion mechanism: The deflector is installed in front of the propeller, which can effectively prevent water flow from directly impacting the propeller blades, reduce the risk of foreign objects such as fishing nets and aquatic plants getting entangled in the propeller, extend the service life of the underwater propulsion mechanism, and reduce equipment failure and maintenance costs caused by foreign objects getting entangled.
[0020] 3. Excellent collection effect: The top of the collection component's frame is connected to a collection net, and the flat area of the collection net is larger than the area enclosed by the frame. A baffle is installed at the bottom of the frame. The baffle can intercept the blown-up garbage, keeping it under the collection net until it is carried by the water flow to the designated area inside the collection net, improving the success rate of garbage collection and preventing garbage from escaping during the collection process.
[0021] 4. Easy to operate: The equipment has a simple structure, consisting of a handheld pole, a fixing component, an underwater propulsion mechanism, a flow guide, and a collection component.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0030] Please see Figure 1-4 This utility model provides a technical solution: a portable underwater debris cleaner, including a handheld handle 1;
[0031] Fixed component 2 is fixedly installed on the handheld rod 1. Fixed component 2 includes two pipe clamps 21. A connecting rod 22 is fixedly connected between the side walls of the two pipe clamps 21. The two pipe clamps 21 are fixedly installed on the handheld rod 1. A triangular rod 23 is fixedly connected to one side of the connecting rod 22. An installation frame 24 is fixedly connected to the inclined rod of the triangular rod 23. A flow guide 4 is fixedly installed on the outside of the installation frame 24. The flow guide 4 can prevent water flow from directly impacting the propeller 32 blades and reduce the risk of foreign objects (such as fishing nets, aquatic plants, etc.) getting entangled.
[0032] The underwater propulsion mechanism 3 is fixedly mounted on the fixed assembly 2. The underwater propulsion mechanism 3 includes a drive motor 31 and a propeller 32. The drive motor 31 is fixedly mounted inside the mounting frame 24, and the propeller 32 is fixedly connected to the output shaft of the drive motor 31. The drive motor 31 is a brushless waterproof motor 3542 and is connected to an external power supply via a series overcurrent protector (50A fuse) to prevent damage to the drive motor 31 from direct connection. The external power supply is a 12-24V portable power supply, which can be placed on the ground. In this case, sufficient wiring for connecting the cleaner is required to prevent damage to the cleaner. The cleaning range is limited, so it can also be placed on a small boat on the water. The power cord needs to use a waterproof plug (IP68 rating). The propeller 32 uses 3-6 blades of nylon composite material, with a diameter of 80-120mm. The drive motor 31 is electrically connected to an electronic speed controller (ESC) to control the speed of the drive motor 31. The motor speed can be adjusted according to the actual situation to adapt to different underwater debris conditions and water environments. The drive motor 31 drives the propeller 32 to rotate, and the blades of the propeller 32 will accelerate the water forward and discharge it. The discharged water flow will blow up the lighter bottom debris.
[0033] Collection component 5 is fixedly mounted on the handheld pole 1 for collecting underwater debris. Collection component 5 includes a frame 51, which is fixedly connected to the handheld pole 1 near the fixed component 2. A collection net 52 is fixedly connected to the top of the frame 51. The mesh size of the collection net 52 is 0.5-2cm to accommodate common lightweight debris such as plastic bags and leaf fragments. A baffle plate 53 is fixedly connected to the bottom of the frame 51. The flat area of the collection net 52 must be larger than the enclosed area of the frame 51. Figure 4 As shown, when this cleaner is in use, underwater debris will be pushed to area A inside the collection net 52.
[0034] To further explain, the drive motor 31 adopts an IP68 waterproof design and is powered by a rated voltage of 50V DC. The rotor of the drive motor 31 is directly connected to the propeller 32, eliminating the transmission shaft loss. The stator winding uses an epoxy resin potting process to achieve underwater insulation. The speed of the drive motor 31 is 1000-5000rpm to adapt to the 80-120mm propeller 32. The fairing 4 is composed of a 316 stainless steel ring frame and an ABS plastic grille.
[0035] To further explain, during the cleanup process, personnel can adjust the position and angle of the handheld pole 1 as needed based on the garbage collection situation to improve the cleanup effect. This can be achieved by considering the relationship between water flow speed, garbage type (lightweight floating debris / semi-sunken garbage), underwater topography (muddy bottom / rocky bottom), and the tilt angle of the handheld pole. For example, in muddy bottom waters, the distance between the propeller and the bottom should be maintained at 10-15cm to avoid stirring up the mud and sand; in rocky bottom waters, the angle needs to be controlled at 30°-45° to prevent the propeller from colliding with the water.
[0036] It should be noted that the underwater propulsion mechanism 3 is existing technology, and those skilled in the art can easily install and operate it; its specific working principle will not be described here. Additionally, this cleaner needs to be manually operated in the water, therefore the water depth it is suitable for cannot exceed the cleaner's chest height. Furthermore, this cleaner can only clean lighter, sunken debris and cannot clean heavier debris (large rocks, metal scrap, etc.).
[0037] It should be noted that this utility model is a portable underwater debris cleaner. When cleaning underwater debris, the location of the power supply should be determined according to the work scenario. If placed on land, a sufficiently long power cord should be prepared, and the power cord should be an IP68 waterproof cable to avoid limiting the cleaning range. If placed on a small boat on the water, the cleaner stands in the water (or on the boat) and holds the end of the handheld rod 1 away from the collection component 5, so that the baffle 53 of the collection component 5 is fully in contact with the bottom. At this time, the handheld rod 1 is kept in an inclined position, while the underwater propulsion mechanism 3 needs to be below the water surface, and the direction of the propeller 32 should be... To clean the underwater surface diagonally below the personnel, the power supply is connected to drive motor 31, which in turn drives propeller 32 to rotate. The propeller blades of propeller 32 accelerate water forward, and the discharged water flow blows up lighter, sunken debris from the bottom. This debris is then carried by the water flow to area A in the collection net 52. A baffle 53 intercepts the blown debris, keeping it below the collection net 52 until it is carried to area A. During cleaning, the personnel can move the handheld pole horizontally at a speed of 0.5-1 m / s to ensure effective debris intake. Compared with existing portable underwater debris cleaners, this invention offers higher cleaning efficiency, reduces labor costs, provides better collection results, and is easy to operate, making it suitable for cleaning underwater debris in small bodies of water.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
