Description

Technical Field

[0001] The present invention relates to the technical field of decontamination devices, and in particular to a bottom cleaning and decontamination device for agricultural aquaculture. Background Art

[0002] Agricultural aquaculture bottom cleaning and decontamination devices are designed to effectively remove impurities from the bottom of aquaculture ponds or aquaculture areas, including bottom mud, residual feed, dead fish, and other sediments. This device typically uses a mechanized or automated system to complete the bottom cleaning work, thereby improving the water quality of the aquaculture environment, reducing the accumulation of harmful substances, and thus promoting the healthy growth of aquaculture organisms. Common bottom cleaning and decontamination devices include suction pipes, mud suction devices, rotary brushes, or water pump systems. These devices can effectively suck up or remove impurities deposited on the bottom of the water;

[0003] This device generally uses a water pump or suction device to suck in impurities from the bottom of the water, and then separates the water and impurities through a filtration system, or through an external discharge system. These devices are usually also equipped with mechanical structures to adjust the water flow and clean the bottom of the pond to adapt to the size of different aquaculture ponds and the types of bottom impurities. In addition to bottom cleaning, some devices may also have the function of regulating water flow and reducing the impact of bottom sediments on water quality, thereby improving the stability of water quality and the sanitary conditions of the aquaculture environment;

[0004] However, the existing technology still has some limitations in bottom cleaning. The current cleaning device generally adopts the method of pumping up water and impurities together for cleaning. There is a problem with this method, that is, it is impossible to thoroughly clean the bottom of the water and effectively pump water at the same time. In addition, the existing technology usually needs to discharge the pumped water to the outside, which will cause a large amount of water loss, increase water consumption in the aquaculture area, and may even affect the stability of water quality. At the same time, the existing equipment lacks an effective collection system for floating objects on the water surface, and cannot clean duckweed, debris, etc. on the water surface at the same time, resulting in the inability to clean the water surface and the bottom of the water simultaneously. In order to improve efficiency and save water resources, this solution proposes a device that can simultaneously clean impurities on the bottom and surface of the water to achieve a more comprehensive cleaning effect and reduce water loss.

[0005] Chinese patent announcement number CN222216901 U discloses an aquaculture bottom cleaning and decontamination device in the field of aquaculture related technology, including a cleaning boat and a slurry pump, wherein a side support plate 1 and a side support plate 2 are fixedly installed on both sides of the cleaning boat, and mounting holes are provided on the side support plate 1 and the side support plate 2. The aquaculture bottom cleaning and decontamination device of the above patent document can be detachably mounted on the cleaning boat, and the sludge at the bottom of the aquaculture pond is scooped up by a cleaning roller, and the sludge is extracted by a slurry pump. The sludge separated by the mud solid-liquid separator remains on the cleaning boat, and the water is discharged back into the pond. The operation is divided into sections, and there is no need to remove the aquatic products in advance. The cleaning roller is provided with a telescopic structure of the cleaning scraper, which will not cause damage to the bottom of the pond during the bottom cleaning process. After the cleaning and bottom cleaning is completed, the bottom cleaning and decontamination power device can be hoisted down as a whole to facilitate the storage and maintenance of the equipment.

[0006] Although the equipment in the above patent document can clean impurities on the bottom of the water during use, it lacks an effective collection device for floating objects on the water surface during actual use, and cannot clean duckweed, debris, etc. on the water surface at the same time, resulting in the inability to clean the water surface and the bottom of the water simultaneously, thereby reducing the cleaning efficiency.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] Example 1, as Figure 1 As shown, the present invention discloses a bottom cleaning and decontamination device for agricultural aquaculture, the device comprises two support legs 1 placed on the bottom of the water, the lower ends of the two support legs 1 are rotatably mounted with rollers, the two rollers are used to assist in pushing the bottom cleaning and decontamination device for agricultural aquaculture, the upper parts of the two support legs 1 are each mounted with a support ring 2, the sides of the two support rings 2 close to each other are each mounted with a fixed ring 3 and a water baffle 4, the water baffle 4 is mounted in the inner cavity of the fixed ring 3, the sides of the two water baffles 4 away from each other are each provided with a bottom cleaning component 7 for pumping water and cleaning the bottom, the sides of the two fixed rings 3 inner cavities close to each other are jointly mounted with a filter for drainage and filtration. Component 8, a circular groove 5 is provided at the axis of the side away from each other of the two water baffles 4, the water inlet ends of the two bottom cleaning components 7 are downward, and the water outlet ends of the two bottom cleaning components 7 are connected to the inner cavity of the filter component 8 through the two circular grooves 5. The tops of the two fixing rings 3 are jointly equipped with a driving component 9 for driving the filter component 8 to perform drainage filtration. A circular groove 2 6 is provided on the upper part of the side away from each other of the two water baffles 4, and a floating component 10 is installed on the upper part of the end away from each other of the two water baffles 4. The water inlet ends of the two floating components 10 are located on the water surface, and the water inlet ends of the two floating components 10 are connected to the inner cavity of the filter component 8 through the circular groove 2 6;

[0035] During use, impurities on the bottom of the water are extracted and cleaned through the bottom cleaning component 7, and the impurities and water generated after cleaning are pumped into the filter component 8 for storage. The floating component 10 can use the buoyancy of the water to float to the surface of the water, and use the tension to collect the scum on the water surface. The collected scum enters the filter component 8 for storage. The driving component 9 drives the filter component 8 to separate the collected water and impurities, so that the impurities are always stored in the filter component 8, and the filtered water is discharged by the filter component 8.

[0036] Example 2, as Figure 2 and Figure 3As shown, in this embodiment, the bottom cleaning component 7 includes a water pump 71. The output end of the water pump 71 is connected to the inner cavity of the filter component 8 through the corresponding circular groove 5. The input end of the water pump 71 is fixedly installed with a connecting cylinder 74 for water inlet. The upper surface of the connecting cylinder 74 is fixedly installed with a sleeve 72 for limiting the guide. The cavity formed by the sleeve 72 and the connecting cylinder 74 is slidably connected with a slide cylinder 73 for moving up and down. The upper part of the slide cylinder 73 and the top wall of the sleeve 72 are fixedly installed with a spring 75 for providing elastic deformation space. The lower part of the inner surface of the slide cylinder 73 is open. An annular groove 76 is provided, and a rotating ring 77 is slidably connected to the inner surface of the annular groove 76. Four brackets 78 are fixedly installed in an annular array on the inner surface of the rotating ring 77. An extension column 79 for transmission is fixedly connected to the side of the four brackets 78 that are close to each other. A turbine 70 for turbulent rotation is fixedly installed at the lower part of the extension column 79. A cleaning cylinder 701 is fixedly installed at the lower part of the four brackets 78. The bottom wall of the cleaning cylinder 701 is flush with the bottom wall of the sliding cylinder 73. A plurality of cleaning blocks 702 arranged in the form of rubber strips are fixedly connected in an annular array at the lower part of the cleaning cylinder 701.

[0037] During use, by bringing the lower end of the slide 73 into contact with the bottom of the water, the slide 73 is squeezed and slides into the cavity formed between the connecting tube 74 and the sleeve 72, and at the same time squeezes and contracts the spring 75 that is fixedly connected to the slide 73 and the sleeve 72. At the same time, by starting the water pump 71, the suction force generated by the input end of the water pump 71 sucks water and impurities into the connecting tube 74 at the same time.

[0038] When water and residue are sucked into the inner cavity of the connecting cylinder 74, the water flow can impact the surface of the turbine 70, thereby driving the turbine 70 to rotate at the lower end of the extension column 79. During the rotation of the turbine 70, the scum passing through its surface can be broken up, and when the turbine 70 rotates, it can simultaneously drive the extension column 79 fixedly connected to it to rotate. The extension column 79 is fixedly connected to the inner surface of the rotating ring 77 through the bracket 78, and the cleaning cylinder 701 is fixedly installed at the lower end of the bracket 78. Therefore, when the turbine 70 rotates, it can simultaneously drive the several cleaning blocks 702 fixedly connected to the lower end of the cleaning cylinder 701 to rotate with the axis of the cleaning cylinder 701 as the center point, thereby achieving the purpose of the several cleaning blocks 702 cleaning the bottom of the water.

[0039] Example 3, as Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 10As shown, in this embodiment, the filter assembly 8 includes a filter cartridge 81. A plurality of filter mesh holes are formed on the outer surface of the filter cartridge 81. Both sides of the outer surface of the filter cartridge 81 are rotatably connected to the inner surfaces of two fixing rings 1 3. An inner gear ring 84 for driving the floating assembly 10 is fixedly connected to the middle of the inner cavity of the filter cartridge 81. A fixing ring 2 82 is fixed to the middle of the outer surface of the filter cartridge 81. The outer surface of the fixing ring 2 82 is fixedly connected to an outer gear ring 83 for engaging with the driving assembly 9 for transmission.

[0040] During use, the water and residue drawn in by the water pump 71 can enter the inner cavity of the filter cartridge 81 through the circular groove 5. When the filter cartridge 81 rotates, the residue can be retained in the inner cavity and the filtered water can be discharged from the outside.

[0041] Furthermore, the ends of the two water retaining plates 4 that are close to each other are fixedly installed with a water pushing assembly 85, and the water pushing assembly 85 includes a main pipe 851, which is fixedly connected to the end of the fixing ring 3 on the same side that is close to each other, and is arranged at the same center position as the circular groove 5 on the same side. The end of the main pipe 851 away from the fixing ring 3 on the same side is fixedly installed with a connecting ring 852, and the inner surface of the connecting ring 852 is fixedly connected to four connecting frames 853 in an annular array. The four connecting frames 853 are connected to a cylinder 855 on the side close to each other and rotate together. The cylinder 855 is arranged at the same center as the main pipe 851, and the end of the cylinder 855 close to the fixing ring 3 on the same side is fixedly connected to a hemisphere 854. The outer surface of the cylinder 855 is fixed with a plurality of spiral plates 856 distributed on the thread.

[0042] During use, when the water pump 71 draws water and impurities into the main pipe 851 through the circular groove 5, the water will continuously impact the surface of the hemisphere 854, causing the direction of the water flow to change. When the water flows through the surfaces of the spiral plates 856, the spiral gaps therebetween accelerate the water flow, reduce the pressure and enhance the adsorption force. The spiral curved surface of the spiral plate 856 guides the water flow to deflect, and the water flow exerts a tangential component of the reaction force on the spiral surface. These tangential forces form a continuous torque in the circumferential direction of the spiral body, thereby satisfying the spiral plate 856 to drive the cylinder 855 to rotate.

[0043] When the cylinder 855 and the spiral plate 856 rotate, the spiral plate 856 can also continuously stir the drawn-in water and residue, so that the residue is always in a diffused state in the water, which facilitates the subsequent treatment of the residue;

[0044] When the cylinders 855 and spiral plates 856 on both sides draw water into the inner cavity of the filter cartridge 81, the water flows in two forces to impact the middle position of the filter cartridge 81, causing the water to gush outward after the collision, thereby achieving the purpose of discharging the water from the filter holes opened on the outer surface of the filter cartridge 81.

[0045] Example 4, as Figure 2 、 Figure 4As shown, in this embodiment, the driving assembly 9 includes a mounting platform 1 91 and a mounting platform 2 92, which are respectively fixedly connected to the upper outer surface of the fixing ring 1 3 on the same side. A partition 93 is fixedly connected to the side of the upper end of the mounting platform 2 92 close to the fixing ring 1 3 on the same side. A housing 94 for waterproofing is fixedly installed on the upper end of the mounting platform 1 91, and a motor 95 is fixedly installed on the bottom wall of the housing 94. The output end of the motor 95 passes through the outer side of the housing 94 and is fixedly connected to a transmission gear 96 that meshes with the outer gear ring 83 through a coupling. A transmission rod 97 is connected to the axis of the transmission gear 96 and is connected to the side close to the partition 93 for common rotation.

[0046] During use, by starting the motor 95, the coupling fixedly connected to the output end of the motor 95 drives the transmission gear 96 fixedly connected to it to rotate. When the transmission gear 96 rotates, since it engages with the outer gear ring 83, it can drive the partition 93 to rotate. The outer gear ring 83 is fixedly installed on the outer surface of the filter cartridge 81, thereby causing the filter cartridge 81 to rotate. When the filter cartridge 81 rotates, the inner cavity of the filter cartridge 81 is continuously stirred. During the rotation of the filter cartridge 81, the water in its inner cavity can be discharged normally from the filter holes on the outer surface of the filter cartridge 81, while the residue is stored in the inner cavity of the filter cartridge 81.

[0047] Example 5, as Figure 2 、 Figure 7 、 Figure 8 and Figure 9 As shown, in this embodiment, the floating assembly 10 includes an L-shaped tube 101. A floating tube 102 is slidably mounted on the upper inner surface of the L-shaped tube 101. A circular air bag 103 is fixedly connected to the lower portion of the floating tube 102. When water enters the floating tube 102, the air bag 103 lifts the air bag 103 under the action of its own buoyancy, and causes the water inlet tray 104 fixedly connected to the upper end of the floating tube 102 to float to the water surface. An extension tube 105 is fixedly connected to the inner wall end of the vertical portion of the L-shaped tube 101. A spoiler assembly 106 is fixedly mounted on the inner surface of the extension tube 105 on the side away from the L-shaped tube 101.

[0048] Furthermore, a plurality of water inlet ports 1041 are formed in a circular array on the outer surface of the water inlet tray 104. In order to reduce the risk of floating objects entering the water inlet tray 104 along with the water and then flowing out again along the edge of the water inlet tray 104, a plurality of barb-shaped flow prevention plates 1042 are fixedly connected in a circular array to the edge of the water inlet tray 104.

[0049] When the float tube 102 is in use, water will flow into the float tube 102 from the opening of the water inlet tray 104. When the float tube 102 is filled with water, the air bag 103 can drive the float tube 102 to float upward under the action of its own buoyancy until the float tube 102 drives the water inlet tray 104 fixed at its upper end to float to the water surface. When the water inlet tray 104 floats to the water surface, the water guide port 1041 opened on its outer surface can continuously break the tension of the water surface, thereby making the water inlet tray 104 move up and down in a small amplitude, so that the water on the water surface and floating objects can continuously flow into the float tube 102 from the opening of the water inlet tray 104. Moreover, under the action of the plurality of flow prevention plates 1042 fixedly connected in an annular array at the edge of the outer surface of the water inlet tray 104, the flow prevention plates 1042 are arranged in a barb shape, so that the leakage of floating objects from the surface of the water inlet tray 104 when the water inlet tray 104 moves upward can be reduced.

[0050] Furthermore, the spoiler assembly 106 includes four connecting blocks 1061, which are all fixedly connected to the inner surface of the extension tube 105. The ends of the four connecting blocks 1061 that are close to each other are commonly fixedly connected to a hollow ring 1062. A rotating rod 1063 is rotatably installed on the inner surface of the hollow ring 1062. An impeller 1064 is fixedly installed on the side of the rotating rod 1063 close to the L-shaped tube 101. The impeller 1064 and the extension tube 105 are arranged at the same center of a circle. Four connecting blocks 2 1065 are fixedly connected in an annular array on the side of the rotating rod 1063 away from the impeller 1064. The outside of the connecting blocks 2 1065 is commonly fixedly connected to a hollow gear 1066. The hollow gear 1066 is rotatably connected to the extension tube 105, and the hollow gear 1066 and the internal gear ring 84 are meshed with each other for transmission.

[0051] During use, when the inner gear ring 84 rotates with the filter cartridge 81, the hollow gears 1066 on both sides mesh with the inner gear ring 84, thereby driving the two hollow gears 1066 to rotate simultaneously. When the hollow gears 1066 rotate, the rotating rod 1063 fixedly connected to them via the second connecting block 1065 rotates on the inner surface of the corresponding hollow ring 1062. When the rotating rod 1063 rotates, the impeller 1064 fixedly connected to it also rotates. When the impeller 1064 rotates, it can generate a thrust in the direction of the hollow gear 1066, so that water and floating objects entering the float tube 102 can be discharged into the inner cavity of the filter cartridge 81 through the extension tube 105.

[0052] The thrust generated by the cylinders 855 and spiral plates 856 on both sides of the above-mentioned middle part on the water will be pushed to the water outlet of the extension tube 105. Therefore, under the action of the thrust generated by the impeller 1064, the thrust generated by it can be offset, so that the water and floating objects in the floating tube 102 can smoothly enter the filter cartridge 81, thereby achieving the purpose of collecting floating objects on the water surface.

[0053] It should be noted that the specific installation methods of the two water pumps 71 and the motor 95, the circuit connection method, and the control method used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention.
