Description

Technical Field

[0001] The invention relates to the technical field of algae cleaning, and in particular to an algae cleaning device. Background Art

[0002] Nowadays, most cities’ rivers produce a large amount of floating algae because of the eutrophication of the water bodies. The wildly growing algae not only affects the beauty of the landscape rivers, but also causes the water quality to deteriorate, the oxygen content in the water to decrease, and the aquatic organisms to decrease.

[0003] The current cleaning method is to use a salvaging device to salvage the algae on the river surface through the circulating salvaging belt at the end of the salvaging device and accumulate it somewhere in the device. Workers on the salvaging device continue to disperse the accumulated algae to handle more algae. However, this algae cleaning method has the following problems: The algae are long, sticky and slippery, making it easy for them to entangle on the surface of the circulating salvage belt, making it impossible to effectively clean them off. As the algae entangle more and more, it will affect the quality of algae cleaning and even cause excessive load and motor overload damage. Summary of the invention

[0004] The present invention provides an algae cleaning device, which solves the problem that the form of cleaning algae with a circulating salvaging belt in the related art cannot effectively clean the algae entangled on the surface thereof, and long-term operation may even damage the motor.

[0005] The technical solution of the present invention is as follows: A water algae cleaning device, comprising: A floating base, wherein the floating base has a first magnetic block and a second magnetic block; A rotating shaft, the rotating shaft is rotatably arranged on the float base; A plurality of salvage rods, wherein the plurality of salvage rods are disposed on the rotating shaft and are arranged along the circumference of the rotating shaft; A cleaning sleeve, wherein the cleaning sleeve is movably arranged on the salvage rod, and the salvage rod passes through the cleaning sleeve, and the cleaning sleeve has a magnetic part. After the rotating shaft rotates, the magnetic part acts on the first magnetic block and the second magnetic block in sequence. After the magnetic part acts on the first magnetic block, the cleaning sleeve moves away from the rotating shaft, and after the magnetic part acts on the second magnetic block, the cleaning sleeve approaches the rotating shaft.

[0006] As a further technical solution, both ends of the cleaning sleeve have magnetic parts, and the float base also has an annular magnetic part, which is composed of the first magnetic block and the second magnetic block. The annular magnetic part is located between several of the magnetic parts. After the rotating shaft rotates, the magnetic part approaches the first magnetic block and the second magnetic block in turn.

[0007] As a further technical solution, the first magnetic block and the second magnetic block are both arc-shaped, the central angle of the first magnetic block is 90°, and the central angle of the second magnetic block is 270°.

[0008] As a further technical solution, the length of the cleaning sleeve is greater than the length of the rotating shaft, and further comprises: Two mounting posts are symmetrically arranged on the float base, both ends of the rotating shaft have mounting grooves, the two mounting posts are respectively arranged in the two mounting grooves, and the rotating shaft is rotatably connected to the mounting posts, and the annular magnetic part is sleeved on the mounting posts.

[0009] As a further technical solution, the salvage rod is arc-shaped, the cleaning sleeve is rectangular, the length direction of the cleaning sleeve is parallel to the rotation axis of the shaft, the cleaning sleeve has a plurality of cleaning ports, the plurality of cleaning ports are arranged at intervals along the rotation axis of the shaft, and the salvage rod passes through the cleaning ports, and the cross-sectional area of ​​the salvage rod is equal to the cross-sectional area of ​​the cleaning port.

[0010] As a further technical solution, it also includes: A plurality of raised cleaning parts are arranged on the cleaning sleeve, the plurality of raised cleaning parts are arranged at intervals along the length direction of the cleaning sleeve, and the raised cleaning parts are arranged on both sides of the salvage rod, and the raised cleaning parts abut against the salvage rod.

[0011] As a further technical solution, the float base is concave in shape, the center of the float base also has a cleaning area, the rotating shaft is rotatably arranged on the top of the float base, and further comprises: A supporting bottom plate is arranged at the bottom of the float base body, and the supporting bottom plate has a salvage opening. After the rotating shaft rotates, the salvage rod is driven to extend into or out of the salvage opening for salvaging algae.

[0012] As a further technical solution, the supporting bottom plate has a material receiving position, the material receiving position is located in the cleaning area and on one side of the salvage port, and further includes: A material guide shaft, the material guide shaft is rotatably disposed on the float base and is located at the material receiving position; A spiral blade is arranged on the material guiding shaft.

[0013] As a further technical solution, the rotation axis of the material guide shaft is parallel to the rotation axis of the rotating shaft, there are two spiral blades, the two spiral blades are symmetrically arranged on the material guide shaft, and the two spiral blades rotate in opposite directions. After the material guide shaft rotates, the two spiral blades are used to push and squeeze the algae to the inner wall of the cleaning area.

[0014] As a further technical solution, it also includes: A baffle is arranged on the supporting bottom plate and fixedly connected to the floating base. The baffle is located around the material guiding shaft and is used to prevent the algae from escaping from the material receiving position.

[0015] The working principle and beneficial effects of the present invention are: In the present invention, multiple salvage rods are arranged along the circumference of the rotating shaft, which increases the coverage area of ​​the single algae cleaning. Compared with traditional manual salvage tools (such as a single net bag, etc.), more algae can be salvaged at one time, improving the cleaning efficiency. For example, when working on a lake with dense algae, a large area of ​​algae can be quickly collected to reduce the cleaning time, and the cleaning sleeve can move on the salvage rod and achieve the movement of moving away from and approaching the rotating shaft through the action of different magnetic blocks on the float base. This ingenious design allows the cleaning sleeve to quickly remove the algae entangled on the salvage rod, avoiding more and more entanglement and damage to the motor, thereby increasing the service life of the cleaning device.

[0016] At the same time, the magnetic principle of the magnetic block is used to complete the movement of the cleaning sleeve on the salvage rod, which saves a lot of unnecessary mechanical structures and does not involve the introduction of chemical agents into the water body, thereby avoiding the damage of chemical agents to aquatic organisms such as fish and shrimps in the water body and the long-term negative impact on the self-purification capacity of the water body ecosystem. Specifically, the magnetic part welded at the end of the cleaning sleeve rotates with the rotating shaft, and it is convenient to interact with the first magnetic block and the second magnetic block in turn. Therefore, under the repulsive force of the first magnetic block, it moves outward from the root of the salvage rod close to the rotating shaft to remove the algae from the salvage rod. Conversely, it moves inward from the end of the salvage rod away from the rotating shaft to avoid affecting the salvage of algae.

[0017] Moreover, the entire device is based on a floating base and can float on the water surface to operate. It can adapt to a variety of water environments such as different depths and different water flow conditions. Whether it is a shallow small lake or pond, or a river with a certain depth and water flow, as long as algae exist on the water surface and near the water surface, the device can carry out the cleaning work well and has high flexibility.

DETAILED DESCRIPTION

[0021] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention.

In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0023] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it 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 it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0025] Reference Figure 1 to Figure 9 , which is the first embodiment of the present invention, provides an algae cleaning device, comprising: a floating base body 1, the floating base body 1 has a first magnetic block 1011 and a second magnetic block 1012; a rotating shaft 2, the rotating shaft 2 is rotatably arranged on the floating base body 1; a plurality of salvage rods 3, the plurality of salvage rods 3 are all arranged on the rotating shaft 2, and the plurality of salvage rods 3 are arranged along the circumference of the rotating shaft 2; a cleaning sleeve 4, the cleaning sleeve 4 is movably arranged on the salvage rod 3, and the salvage rod 3 passes through the cleaning sleeve 4, the cleaning sleeve 4 has a magnetic part 401, after the rotating shaft 2 rotates, the magnetic part 401 acts on the first magnetic block 1011 and the second magnetic block 1012 alternately in sequence, when the magnetic part 401 acts on the first magnetic block 1011, the cleaning sleeve 4 is away from the rotating shaft 2, and when the magnetic part 401 acts on the second magnetic block 1012, the cleaning sleeve 4 is close to the rotating shaft 2.

[0026] Working process: First, place the algae cleaning device on the water surface where algae need to be cleaned, and rely on the floating base 1 in the form of an inflatable boat to make the whole device float on the water surface; then, start the inflatable boat to travel on the water surface, and control the motor to make the rotating shaft 2 start to rotate. When the rotating shaft 2 rotates, it will drive a number of salvage rods 3 arranged along the circumference around it to continuously extend below the water surface and then extend out of the water surface, thereby realizing the function of continuously catching algae. This requires ensuring that after the salvage rod 3 rotates with the rotating shaft 2, its length can reach below the bottom of the floating base 1 to ensure that the algae can be salvaged.

[0027] Action of salvaging and removing algae: after the algae are salvaged and the salvage rod 3 floats to the surface, the magnetic part 401 welded to the end of the cleaning sleeve 4 will continue to rotate with the rotation shaft 2, and will gradually approach the first magnetic block 1011 on the float base 1. Due to the repulsive magnetic force between the magnetic part 401 and the first magnetic block 1011, the cleaning sleeve 4 will move along the salvage rod 3 away from the rotation shaft 2. In this process, the cleaning sleeve 4 can push the algae around it and on the path it passes, so that after the algae are salvaged, the algae will be pushed away from the salvage rod 3 and collected at a certain position of the float base 1.

[0028] Reset action: Continue to rotate, the magnetic part 401 at the end of the cleaning sleeve 4 slowly approaches the second magnetic block 1012, and due to the attractive magnetic force between the magnetic part 401 and the second magnetic block 1012, the cleaning sleeve 4 will approach the rotating shaft 2 along the salvage rod 3, and the salvage rod 3 sinks under the water surface, preparing for the next salvage, avoiding interference with the salvage action and affecting the subsequent algae removal operation.

[0029] The cleaning sleeve 4 continuously repeats the above-mentioned action of moving away from and approaching the rotating shaft 2, and cooperates with the cyclic salvaging action to complete the automatic and rapid cleaning of algae, greatly reducing the labor intensity.

[0030] Using magnetic force to control the position of the cleaning sleeve 4 is a precise control method. By carefully designing the positions of the first magnetic block 1011 and the second magnetic block 1012 on the float base 1, and the magnetic strength of the magnetic part 401 of the cleaning sleeve 4, the moving distance of the cleaning sleeve 4 on the salvage rod 3 can be accurately controlled, so that the cleaning sleeve 4 set on the salvage rod 3 can completely remove the salvaged algae to avoid omissions, and magnetic control is a relatively simple and reliable non-contact control method. Compared with traditional mechanical transmission control (such as complex connecting rod mechanisms, gear mechanisms, etc.), magnetic control has no direct mechanical friction and physical connection. During the long-term operation of the device, failures caused by wear and jamming of mechanical parts are avoided, and the service life of the cleaning device is improved.

[0031] The algae cleaning device does not involve the introduction of chemical agents into the water body, thus avoiding the harm of chemical agents to aquatic organisms such as fish and shrimp in the water body and the long-term negative impact on the self-purification capacity of the water ecosystem, etc., and is in line with the current requirements for environmental protection of water bodies and protection of the ecological environment.

[0032] Furthermore, both ends of the cleaning sleeve 4 have a magnetic part 401, and the float base 1 also has an annular magnetic part 101, which is composed of a first magnetic block 1011 and a second magnetic block 1012. The annular magnetic part 101 is located between several magnetic parts 401. After the rotating shaft 2 rotates, the magnetic part 401 approaches the first magnetic block 1011 and the second magnetic block 1012 in turn.

[0033] In this embodiment, magnetic parts 401 are welded at both ends of the cleaning sleeve 4, which can better accept the corresponding magnetic force. Compared with the design with a magnetic part 401 at only one end, it can move more smoothly on the salvage rod 3; at the same time, since the magnetic part 401 makes a circular motion driven by the rotating shaft 2, in order to ensure that it can smoothly act with the first magnetic block 1011 and the second magnetic block 1012 in sequence, the two are designed to form an annular magnetic part 101, and the annular magnetic part 101 is located between several magnetic parts 401, and the annular design can be conveniently mounted on the rotating shaft 2, welded to the float base 1, and can be stably supported.

[0034] At the same time, the annular magnetic part 101 provides a stable magnetic environment. During the operation of the algae cleaning device, the movement trajectory of the cleaning sleeve 4 is more stable and predictable. Compared with simple linearly arranged magnetic blocks, the annular magnetic part 101 ensures that the cleaning sleeve 4 is always subjected to uniform and stable magnetic force during the movement, reducing the shaking and offset of the cleaning sleeve 4 caused by uneven magnetic force. This is crucial for cleaning devices that work in complex water environments for a long time, and can effectively prevent damage to the device caused by abnormal movement of the cleaning sleeve 4, thereby improving the reliability and service life of the device.

[0035] Furthermore, the first magnetic block 1011 and the second magnetic block 1012 are both arc-shaped, the central angle of the first magnetic block 1011 is 90°, and the central angle of the second magnetic block 1012 is 270°.

[0036] In this embodiment, Figure 3 , 4 As shown, the first magnetic block 1011 and the second magnetic block 1012 which specifically constitute the ring are arc-shaped, and the central angles of the two are configured to be 90° and 270°. The first magnetic block 1011 accounts for a relatively small proportion because it is only necessary to provide repulsive magnetic force to the magnetic part 401 for a short period of time after the salvage rod 3 salvages the algae to remove the algae on the salvage rod 3. Otherwise, the cleaning sleeve 4 needs to be kept on the end of the salvage rod 3 close to the rotating shaft 2.

[0037] Furthermore, the length of the cleaning sleeve 4 is greater than that of the rotating shaft 2, and also includes: two mounting columns 5, the two mounting columns 5 are symmetrically arranged on the float base 1, both ends of the rotating shaft 2 have mounting grooves 201, the two mounting columns 5 are respectively arranged in the two mounting grooves 201, and the rotating shaft 2 is rotatably connected to the mounting columns 5, and the annular magnetic part 101 is sleeved on the mounting columns 5.

[0038] In this embodiment, in order to further stably support the rotating shaft 2 on the floating base 1, two groups of mounting columns 5 are symmetrically welded thereon, and the mounting grooves 201 opened at both ends of the rotating shaft 2 are respectively interference fit with the two groups of mounting columns 5 to realize the motor-driven rotation connection and stably control its rotation relative to the mounting columns 5. At the same time, the mounting columns 5 with a smaller cross-sectional area than the rotating shaft 2 just provide a sleeve position for the annular magnetic part 101 to provide stable support.

[0039] In order to ensure that the annular magnetic parts 401 on both sides can act on both ends of the cleaning sleeve 4, the length of the cleaning sleeve 4 is set to be greater than the length of the shaft 2. The magnetic parts 401 at both ends protrude from the shaft 2 and are located outside the annular magnetic part 101 to facilitate the magnetic effect thereon.

[0040] Furthermore, the salvage rod 3 is arc-shaped, the cleaning sleeve 4 is rectangular, the length direction of the cleaning sleeve 4 is parallel to the rotation axis of the shaft 2, the cleaning sleeve 4 has a plurality of cleaning ports 402, the plurality of cleaning ports 402 are arranged at intervals along the rotation axis of the shaft 2, and the salvage rod 3 passes through the cleaning port 402, and the cross-sectional area of ​​the salvage rod 3 is equal to the cross-sectional area of ​​the cleaning port 402.

[0041] In this embodiment, in order to further stably support the rotating shaft 2 on the floating base 1, two groups of mounting columns 5 are symmetrically welded thereon, and the mounting grooves 201 opened at both ends of the rotating shaft 2 are respectively interference fit with the two groups of mounting columns 5 to realize the motor-driven rotation connection and stably control its rotation relative to the mounting columns 5. At the same time, the mounting columns 5 with a smaller cross-sectional area than the rotating shaft 2 just provide a sleeve position for the annular magnetic part 101 to provide stable support.

[0042] In order to ensure that the annular magnetic parts 401 on both sides can act on both ends of the cleaning sleeve 4, the length of the cleaning sleeve 4 is set to be greater than the length of the rotating shaft 2. The magnetic parts 401 at both ends protrude from the rotating shaft 2 and are located on one side of the annular magnetic part 101 to facilitate the magnetic effect thereon.

[0043] Furthermore, it also includes: a plurality of raised cleaning parts 6, which are all arranged on the cleaning sleeve 4, and are arranged at intervals along the length direction of the cleaning sleeve 4, and the raised cleaning parts 6 are arranged on both sides of the salvage rod 3, and the raised cleaning parts 6 are abutted against the salvage rod 3.

[0044] In this embodiment, a plurality of raised cleaning portions 6 are welded on the cleaning sleeve 4 along its length direction to further improve the effect of removing the entangled algae, and avoid the cleaning sleeve 4 moving to the end of the salvage rod 3 but not separating to the extent that there is still algae entangled on the salvage rod 3. At this time, the raised cleaning portion 6 can play a role, and push the remaining algae away from the end of the salvage rod 3 and collect it into the floating base 1, thereby reducing the omission of algae; and for some algae stubbornly attached to the salvage rod 3 or the inner wall of the cleaning sleeve 4, the raised cleaning portion 6 can better remove them from the attachment position by friction and extrusion with them, so it is necessary to design that both sides of the salvage rod 3 are provided with raised cleaning portions 6, and the raised cleaning portions 6 are in contact with the salvage rod 3, wherein the material of this part can be selected from wear-resistant and smooth materials, which effectively overcomes the adhesion of the algae and improves the service life.

[0045] Furthermore, the float base 1 is concave in shape, and a cleaning area 102 is provided at the center of the float base 1. The rotating shaft 2 is rotatably arranged on the top of the float base 1, and also includes: a supporting bottom plate 7, the supporting bottom plate 7 is arranged at the bottom of the float base 1, and the supporting bottom plate 7 has a salvage opening 701. After the rotating shaft 2 rotates, it drives the salvage rod 3 to extend into or out of the salvage opening 701 for salvaging algae.

[0046] In this embodiment, the inflatable boat-type floating base 1 is generally in the shape of a concave letter "U", and the cleaning area 102 in the middle is just at the top of the rotating installation shaft 2, which is achieved by symmetrically welded installation columns 5. The supporting base plate 7 welded at the bottom of the cleaning area 102, on the one hand, has a salvage port 701 directly below the rotating shaft 2, which is convenient for the salvage rod 3 to salvage algae. On the other hand, it provides convenience for the subsequent algae processing. For example, a special collection net or container can be set in the cleaning area 102 to collect the salvaged algae in a unified manner, and then further processed (such as transporting to the shore for processing, for other production and processing, etc.), avoiding the problem of algae being dispersed on the water surface and difficult to collect and process.

[0047] Furthermore, the supporting bottom plate 7 has a material receiving position 702, which is located in the cleaning area 102 and on one side of the salvage port 701. It also includes: a material guide shaft 8, which is rotatably set on the floating base 1 and is located at the material receiving position 702; and a spiral blade 9, which is set on the material guide shaft 8.

[0048] In this embodiment, in order to improve the carrying and processing capacity of the algae cleaning device for algae and avoid simple accumulation on the supporting base plate 7, which requires cleaning every once in a while, a guide shaft 8 and an electric drive structure are rotatably installed on the float base 1 through a bearing seat and a bearing, and both ends of the guide shaft 8 are buried in the inner wall of the cleaning area 102 to avoid the problem of algae entanglement; when the cleaning sleeve 4 pushes the algae on the salvage rod 3 to the receiving position 702 of the supporting base plate 7, the spiral blades 9 welded on the guide shaft 8 can push it and squeeze it toward the inner wall of the cleaning area 102 to avoid excessive accumulation of algae at the receiving position 702.

[0049] In actual algae cleaning work, the collected algae often need to be transferred to the shore or other processing equipment for further processing. The spiral blades 9 can push the algae at the receiving position 702 to a convenient location for collection in an orderly manner by continuously rotating, such as to a collection container arranged at the edge of the floating base 1 or to the entrance of a transmission channel connected to the shore, etc., which greatly facilitates the transfer process of the algae from the cleaning device to the subsequent processing link and reduces the workload of manual intervention and sorting of the algae.

[0050] Furthermore, the rotation axis of the guide shaft 8 is parallel to the rotation axis of the rotating shaft 2. There are two spiral blades 9, which are symmetrically arranged on the guide shaft 8 and have opposite rotation directions. After the guide shaft 8 rotates, the two spiral blades 9 are used to push and squeeze the algae to the inner wall of the cleaning area 102.

[0051] In this embodiment, two sets of spiral blades 9 are further symmetrically welded on the guide shaft 8, and the two sets of spiral blades 9 rotate in opposite directions, so that the spiral blades 9 can continuously rotate to push the algae to the inner walls on both sides of the cleaning area 102, thereby accelerating the processing efficiency of the algae at the receiving position 702; the guide shaft 8 and the rotating shaft 2 are both placed horizontally, which is convenient for early installation and completion of the action.

[0052] Furthermore, it also includes: a baffle 10, which is arranged on the supporting bottom plate 7 and fixedly connected to the floating base 1. The baffle 10 is located around the material guiding shaft 8 to prevent the algae from escaping from the material receiving position 702.

[0053] In this embodiment, Figure 1 , 6 -8, in order to prevent the algae pushed away from the algae cleaning device by the spiral blade 9 and to provide support for the extrusion effect, baffles 10 are welded around the guide shaft 8 to play a blocking role. The algae are constrained in the receiving position 702, and the pushing effect of the spiral blade 9 on the algae will be more concentrated and effective when it rotates.

[0054] The baffle 10 is arranged around the material guiding shaft 8, which clearly divides the processing area of ​​the algae in the material receiving position 702, specifically the arc-shaped baffle 10 in the center and the inclined baffles 10 at both ends. The arc-shaped baffle 10 is convenient for exerting a pushing effect, and the inclined baffle 10 makes more comprehensive use of the space of the supporting bottom plate 7, increases the space for squeezing the algae, and collaboratively and efficiently completes the algae cleaning and subsequent processing tasks.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
