Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, and more specifically to a water conservancy engineering algae collection device. Background Technology

[0002] Algae control is crucial in reservoir and river management. Currently, the main methods for algae removal and collection include: mechanical removal, physical removal, biological removal, and chemical removal. Among these:

[0003] Biological and chemical removal methods use the release of natural enemies of algae or chemical substances to achieve the purpose of cleaning. The main problem with these methods is that the amount of release needs to be weighed according to the amount of work involved. If not handled properly, it will disrupt the ecological balance of the area and damage the environment.

[0004] Physical cleaning methods typically involve aeration, which uses water flow to achieve cleaning. Although it is pollution-free, the effect is not very noticeable and it is not suitable for larger areas.

[0005] Mechanical removal is the most common method, which involves using mechanical equipment to remove algae. Its advantages are thorough removal and obvious results. Common mechanical removal methods include manual retrieval and mechanical excavation. Manual retrieval refers to manually removing algae with the aid of tools, and is only suitable for small reservoirs. Mechanical excavation involves using excavators and other mechanical equipment to dig out the algae from the bottom of the reservoir. It is suitable for large reservoirs, but the operation is cumbersome, time-consuming, and labor-intensive, and it can damage the reservoir environment to some extent. It also requires a large operating space and is not suitable for small-scale algae removal. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention proposes a water conservancy project algae collection device. This device features a modular design, allowing for disassembly and reassembly based on the size of the water area to be cleaned. It is suitable for algae collection in waters of varying sizes and facilitates the collection and cleaning of algae after cleaning. This ensures effective algae removal while avoiding damage to the environment and ecosystem.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A water conservancy project algae collection device, comprising:

[0009] The cleaning expansion seat assembly consists of multiple cleaning expansion seats connected in series from left to right. Any two cleaning expansion seats can be detachably assembled. Each cleaning expansion seat is a shell structure with an open top and an internal cavity. The cavity is divided into an upper algae cleaning zone and a lower drainage zone by the grid bars at the lower end. The cleaning filter box with an open top and filter holes is supported by the grid bars and is fitted and detachably built into the upper algae cleaning zone. A gap is maintained between the filter box and the inner wall of the cleaning expansion seat for filtering and collecting algae. The filtered water is discharged into the lower drainage zone through the filter holes. A worm gear is built into the lower drainage zone. The lower drainage zones of the multiple cleaning expansion seats are connected from left to right and communicate with the inside of the control assembly connector.

[0010] The control unit is detachably encapsulated on the left side of the cleaning expansion unit. It has a built-in water pump to extract water from the drainage area under each cleaning expansion unit and discharge it outside the device. It also has a built-in drive unit to provide driving force, which is transmitted through the transmission mechanism at the bottom of the device to drive each worm gear to rotate synchronously.

[0011] The sealing assembly is detachably encapsulated on the right side of the cleaning expansion assembly;

[0012] A float is installed on top of the device, and the entire device floats on the water surface via the float, while the cleaning filter box is located below the water surface;

[0013] The solar power supply unit is located on top of the device, protruding above the water surface, and is used to power the various electrical components on the device.

[0014] The structural features of this invention also lie in:

[0015] The detachable assembly structures between two adjacent cleaning expansion seats, between the control assembly seat and the cleaning expansion seat, and between the sealing assembly seat and the cleaning expansion seat are the same.

[0016] The tops of two adjacent cleaning expansion seats, the top of the control assembly seat and the top of the cleaning expansion seat, and the top of the sealing assembly seat and the top of the cleaning expansion seat are all detachably assembled via a locking assembly. The locking assembly includes a locking plate, a locking groove, and a locking screw. The top of the connecting ends of two adjacent cleaning expansion seats, the top of the connecting end of the control assembly seat and the cleaning expansion seat, and the top of the connecting end of the sealing assembly seat and the cleaning expansion seat have recessed and interconnected locking grooves. The locking plate has two screw holes, which are fitted into the two locking grooves and fastened to each locking groove at the screw holes by locking screws.

[0017] The bottom ends of two adjacent cleaning expansion seats, the bottom ends of the control assembly and the cleaning expansion seat, and the bottom ends of the sealing assembly and the cleaning expansion seat are all detachably assembled via locking components. The locking components include a locking screw, a locking groove, and an operating groove. On the bottom ends of the two adjacent cleaning expansion seats, the bottom ends of the control assembly and the cleaning expansion seat, and the bottom ends of the sealing assembly and the cleaning expansion seat, there is a locking groove in one location and an operating groove in another location. A through locking threaded hole is formed at the junction of the two grooves. The locking screw is threaded through the locking threaded hole and passes between the locking groove and the operating groove. One end of the locking screw located in the operating groove is coaxially fixed with an anti-slip rotating block with anti-slip texture on its outer surface, and is fitted with a rotatable locking push plate. The two ends of the locking push plate are fitted on two spring shafts fixed in the operating groove. The locking push plate is tensioned with the inner wall of the operating groove by a locking spring coaxially fitted on the spring shaft. The tension of the locking spring causes it to tightly abut against the inner wall of the operating groove directly opposite it along the axial direction of the locking screw. The deformation direction of the locking spring is set along the axial direction of the locking screw and is in a compressed state.

[0018] The driving device is a stepper motor built into the control assembly base. It drives multiple worm gears to rotate synchronously through a chain drive mechanism. The chain drive mechanism includes, in sequence along the power transmission direction, a power sprocket, a tension sprocket, a positioning sprocket, and a transmission sprocket, as well as a transmission chain. The power sprocket is coaxially connected to the output shaft of the stepper motor. The lower end of the axle of each worm gear passes through the lower drainage area and protrudes from the bottom of the device, and is coaxially connected to a transmission sprocket. The transmission chain is wound around the power sprocket, a pair of tension sprockets, and each transmission sprocket. It is tensioned by a pair of tension sprockets. The tension of the pair of tension sprockets is adjustable through a tension adjustment mechanism. A pair of rotatable positioning sprockets are symmetrically arranged on both sides of the transmission chain and mesh with the outer side of the transmission chain through their sprocket teeth. The position and inner width of the transmission chain are positioned by a pair of positioning sprockets. The positioned transmission chain can accommodate each transmission sprocket and engage with each transmission sprocket in sequence.

[0019] A pair of tension sprockets are symmetrically arranged on both sides of the conveyor chain, and their relative distance is adjustable by the tension adjustment mechanism. The tension adjustment mechanism includes a screw, a nut, an adapter shaft, a slider, and a groove. The tension sprockets are rotatably mounted on the adapter shaft. One end of the adapter shaft extends upward into the control assembly seat and is slidably positioned in the groove within the control assembly seat via the slider. The other ends of the adapter shafts of the two tension sprockets extend downward outward to the bottom of the device and are respectively fixed to a section of screw. The external threads on the two sections of screw have opposite directions of rotation and are arranged along the collinear direction of the center of the pair of tension sprockets. The opposite ends are kept apart and are movably connected by a nut. The nut can rotate around the central axis and has two internal threads with opposite directions of rotation, which respectively engage with the external threads of the two sections of screw.

[0020] The control assembly base and the cleaning expansion base are equipped with floats on the front and rear sides of the top, and the floats on the same side are connected in series in the left and right direction.

[0021] The cleaning filter box is divided into two cleaning zones, one in front and one in back, by a partition with filter holes. The cleaning filter box rests on the inner upper edge of the cleaning expansion seat by the horizontal flanges on the front and rear sides of the top, and the resting part is set with a matching stepped structure. The stepped surface of the stepped structure is used to position the cleaning filter box in the upper algae cleaning zone.

[0022] The solar power supply assembly includes a solar panel supported on top of the control group base by a power supply bracket and exposed above the water surface, as well as a solar controller and a solar circulating battery pack. The solar battery pack and the solar controller are built into the control group base and electrically connected to the solar panel. The drive device and the water pump are powered by the solar battery pack.

[0023] The device has lugs at the bottom left and right sides for connecting anchor chains or anchors.

[0024] Compared with existing technologies, the beneficial effects of this invention are reflected in:

[0025] This invention employs a split structure, allowing for a variable number of cleaning expansion seats for algae removal, making it suitable for algae removal needs of water areas of different sizes and with a wide range of applications. It utilizes a detachable cleaning filter box to filter and collect algae, and a water pump with a drive device via a transmission mechanism to rotate a worm gear, accelerating water flow and collection. This results in fast and efficient algae removal, while also facilitating subsequent processing of the removed algae. Furthermore, it avoids pollution and damage to the cleaned water environment.

[0056] The following are detailed examples of disassembly, assembly, and use of the device.

[0057] For disassembly and assembly instructions, please refer to:

[0058] Firstly, the disassembly and assembly between two adjacent cleaning expansion seats 2, between the control assembly connector 1 and the cleaning expansion seat 2, and between the sealing assembly connector 2 and the cleaning expansion seat 2:

[0059] Taking two adjacent cleaning expansion bases 2 as an example, the tops are connected and disassembled using a locking assembly. The two cleaning expansion bases 2 are joined together so that the locking slots 34 at their tops are aligned to form a communicating groove. The locking plate 27 is then placed into the aligned locking slot 34, with the two screw holes on the locking plate 27 located in the locking slots 34 on both sides. The locking screws 26 are then inserted and tightened to achieve the assembly between the tops of the two cleaning expansion bases 2. Disassembly is similar.

[0060] The bottom ends are connected by a locking assembly for disassembly / assembly. The two cleaning expansion seats 2 are joined together, with the locking groove 8 on one cleaning expansion seat 2 aligned with the operating groove 9 on the other cleaning expansion seat 2. A through locking threaded hole is formed at the joint. The anti-slip block is rotated so that the locking screw 2417 is screwed into the locking threaded hole, passing through the locking groove 8 and the operating groove 9. Under the elastic force of the locking spring, the locking push plate 25 is pressed tightly against the inner wall of the opposite operating groove 9 along the axial direction of the locking screw 2417, further locking the locking screw 2417. Disassembly is the same.

[0061] Second, the assembly of the single cleaning expansion seat 2;

[0062] Using the lifting hole on the partition plate 30, place the cleaning filter box 4 into the upper algae removal area. It rests on the grid bar 29 under its own weight, so that the horizontal flange of the cleaning filter box 4 rests on the inner upper edge of the cleaning expansion seat 2 and is fixed by magnetic force; disassembly is the same.

[0063] Thirdly, the adjustment of the transmission mechanism;

[0064] Based on the size of the water area to be cleaned, select an appropriate number of cleaning expansion seats 2 and assemble the device in the manner described above. Then, adjust the transmission mechanism. Wrap the transmission chain 12 around the power sprocket 15, tension sprocket 14, and each transmission sprocket 11, and position it using a pair of positioning sprockets 13. Then, rotate the nut 31 to adjust the distance between the pair of tension sprockets 14 until they tension the transmission chain, thus completing the adjustment of the transmission mechanism.

[0065] For usage instructions, please refer to:

[0066] The device is placed in the water area to be cleaned, floating in the water, with the cleaning filter box 4 submerged. The water pump 16 and the stepper motor 19 are started. The water pump 16 draws water into the cleaning filter box 4, which then flows through the filter holes into the lower drainage area and is pumped out of the device by the water pump 16. The algae are collected in the cleaning filter box 4. During this process, driven by the stepper motor 19 and driven by the transmission mechanism, each worm gear 28 rotates synchronously, generating eddies that accelerate the flow and discharge of water, further accelerating the collection process.

[0067] After the algae removal is complete, remove the device and then remove the cleaning filter box 4 to collect the cleaned algae.

[0068] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
