Description

Technical Field

[0001] The invention belongs to the technology of blue algae salvaging equipment, and in particular relates to an automatic unloading device for blue algae salvaging and a system thereof. Background Art

[0002] Blue algae often breed and explode in summer. In some nutrient-rich water bodies, blue algae have strong reproductive capacity and adaptability. Once the environment is suitable, a large number of blue algae will be generated, quickly gather and float, forming a layer of blue-green and fishy foam on the water surface, which is called "water bloom", causing adverse effects on the water environment. The large-scale outbreak of blue algae is called "green tide", which will cause serious deterioration of water quality and directly endanger human health and sustainable development of social economy: First, a large number of algae consume dissolved oxygen in the water body, causing the lake to enter an anaerobic state, thereby triggering or accelerating the release of endogenous nutrients at the bottom of the lake, causing high nutrient load in the water body and then producing algae bloom, leading to a vicious cycle. The occurrence of water bloom will have an adverse impact on the entire aquatic ecological environment, which will lead to a decrease in the stability and diversity of aquatic organisms and a significant decrease in the economic benefits of aquaculture. Second, blue algae bloom will affect the normal living water supply of urban residents, which is particularly serious for cities that rely on eutrophic water bodies as drinking water sources. On the one hand, algae in the water will greatly increase the concentration of chemical oxygen demand, biological oxygen demand, and suspended solids, increasing the burden of water treatment; on the other hand, raw water containing a large amount of algae will easily clog the filter tank after entering the water treatment plant, and produce toxic byproducts such as chloroform during chlorination disinfection, which will cause difficulties in filtering the water treatment plant, thereby increasing the operating cost of the water plant. In addition, the secondary metabolites of algae are easy to react with coagulants during the coagulation process, which reduces the treatment effect and increases the amount of coagulants, and the generated complexes will cause corrosion of the pipe network. In severe cases, a large number of blue algae blooms accumulate and degrade, producing odor substances such as methyl mercaptan, methyl sulfide, geosmin, and citral, which deteriorate the water quality of the water supply and lead to a water supply crisis. Third, since some algae can also secrete toxins, causing poisoning of birds, cattle, sheep and other animals, and may also have mutagenic effects, there is also a great potential danger to humans, which seriously affects the quality of drinking water and damages human health. Fourth, blue algae blooms are also extremely unfavorable to the development of leisure and tourism. Once the water body is eutrophicated, it will lead to decreased transparency, turbidity, and odor, which will seriously affect the aesthetic value of the lake area and reduce or eliminate the tourism value of the water area.

[0003] In order to reduce pollution and eliminate the odor of blue algae, it is necessary to remove the accumulated water bloom blue algae. At present, the most environmentally friendly and effective method for cleaning blue algae is through mechanical algae removal, but manual algae removal and unloading are labor-intensive, and the efficiency and automation are low. For this reason, we propose an automatic unloading device and system for blue algae salvage. Summary of the invention

[0026] The structural features of the present invention are now described in detail with reference to the accompanying drawings.

[0027] See also Figure 1-4 , an automatic unloading device for catching blue algae, comprising a supporting base 1, a walking wheel 2 is provided at the bottom of the supporting base 1, a traction rod 3 is provided at one side of the supporting base 1, a tray 4 is provided above the supporting base 1, and a linear lifting drive device is provided between the tray 4 and the supporting base 1;

[0028] A support arm 10 is provided on the tray 4, and a plurality of reinforcing ribs 11 are provided along the length direction of the support arm 10, and a rotation driving device is provided between the support arm 10 and the tray 4;

[0029] A counterweight assembly is provided at one end of the support arm 10, and a parking portion for parking the blue algae salvaging equipment is provided at the other end.

[0030] The automatic unloading device for salvaging blue algae of the present invention can automatically transport the blue algae salvaging equipment in the water area to the river bank for unloading. The degree of automation can effectively improve the salvaging efficiency of blue algae and reduce the labor intensity of salvaging and unloading of salvage personnel.

[0031] Specifically, when in use, the automatic unloading device for salvaging blue algae can be towed to the shore of the water area to be salvaged and fixed, and then the support arm 10 is controlled to place the parking part into the water area, see Figure 3 , when the linear lifting drive device is in working state 1, the linear lifting drive device is in a fully retracted state, the parking part is in a semi-submerged state in the water area, and the blue algae salvaging equipment can walk into the parking part. When the blue algae salvaging equipment enters the parking part, the linear lifting drive device rises, see Figure 4 When the linear lifting drive device is in working state 2, the linear lifting drive device is in a fully extended state, the shutdown part is connected to the blue algae salvaging equipment and is separated from the water surface, and then the rotating drive device rotates the blue algae salvaging equipment to the river bank for unloading operations.

[0032] See also Figure 1 and 2Furthermore, the linear lifting drive device includes a plurality of telescopic cylinders 5, which are evenly distributed along the circumference of the pallet 4 below the pallet 4, one end of the telescopic cylinder 5 is fixed to the support base 1, and the other end is fixed to the pallet 4, and the telescopic cylinder 5 is connected to the power unit hydraulic pump through an oil circuit.

[0033] A plurality of telescopic cylinders 5 are provided to increase the lifting thrust on the one hand and to allow the pallet 4 to receive a balanced thrust on the other hand. An electromagnetic valve for controlling the oil supply is provided on the oil circuit of the telescopic cylinder 5. The electromagnetic valves on the plurality of telescopic cylinders 5 can work synchronously under the control of the controller.

[0034] See also Figure 1 and 2 Furthermore, the rotary drive device includes a driven gear disc 6 and a rotary drive motor 8. The axial position of the driven gear disc 6 is fixed on the tray 4 through a rotary bearing 7. The support arm 10 is laterally fixed on the top axial line of the driven gear disc 6. The rotary drive motor 8 is fixed on one side of the tray 4. A driving gear 9 for driving the driven gear disc 6 to rotate is provided on the output end of the rotary drive motor 8. The driving gear 9 is meshed with the driven gear disc 6.

[0035] Providing a large-diameter driven gear 6 and a small-diameter driving gear 9 can improve the rotation strength of the rotary drive device, reduce the power requirement of the rotary drive motor 8, and also protect the rotary drive motor 8.

[0036] See also Figure 1 Furthermore, the counterweight assembly includes a counterweight block 14 and a vertical plate 15 arranged on the counterweight block 14. Both sides of the vertical plate 15 are provided with slide grooves 16 along their length direction. The ends of the support arms 10 corresponding to the slide grooves 16 are provided with sliders 12 matching the slide grooves 16. The sliders 12 are movably connected in the slide grooves 16 in a sliding manner.

[0037] The counterweight block 14 is provided to provide good support and balance for the support arm 10 when the blue algae salvage equipment is lifted. The purpose of providing the long strip chute 16 is to reduce the force exerted by the counterweight block 14 on the support arm 10. Figure 3 In working state 1, the counterweight 14 is supported by the ground and does not exert pressure on the support arm 10. The shutdown unit is in a semi-submerged state and is subject to buoyancy, which also does not exert pressure on the support arm 10. This can reduce the strength of the support arm 10. Figure 3 In working state 2, one end of the support arm 10 will lift the counterweight 14 and the other end will lift the shutdown part, so that the force balance of the support arm 10 can be achieved.

[0038] See also Figure 1 and 2Further, the shutdown portion includes a support plate 17, and symmetrical ears 18 are provided at the upper and lower ends of the support plate 17 facing the same side, and a smooth rod 19 is fixed between the ears 18 at both ends of the support plate 17. A sleeve 13 is provided at the end of the support arm 10 away from the counterweight assembly, and the smooth rod 19 is movably connected in the sleeve 13 in a sliding manner. A carrier plate 20 for parking the cyanobacteria salvage equipment is provided at the bottom of the support plate 17 away from the ear 18. The carrier plate 20 is used to park the cyanobacteria salvage equipment. Guard plates are provided on both sides of the carrier plate 20. A leakage hole 21 corresponding to the unloading port of the cyanobacteria salvage equipment is provided at the bottom of the carrier plate 20. A float 24 is fixed at the bottom of the carrier plate 20 and located outside the leakage hole 21. The float 24 is an air bag with adjustable air pressure.

[0039] With the cooperation of the float 24 and the smooth rod 19, the carrier plate 20 can adjust itself as the water level changes, always keeping the diving depth of the parking part the same, which is beneficial to the entry of blue algae salvage equipment. Since the buoyancy of the float 24 is a constant, the gravity of the parking part is also a constant. After the forces are balanced, the smooth rod 19 on the parking part will rise or fall along the sleeve 13 as the water level changes.

[0040] See also Figure 1 and 2 Furthermore, a top plate 22 is fixedly provided above the carrier plate 20, and a wireless charging transmitting module 23 for wireless charging is provided on the top plate 22. The wireless charging transmitting module 23 can be matched with the wireless charging receiving module on the top of the cyanobacteria salvage equipment. The wireless charging transmitting module 23 can wirelessly charge the cyanobacteria salvage equipment to supplement the energy loss of the cyanobacteria salvage equipment during the salvage operation.

[0041] The present invention also provides an automatic unloading system for blue algae salvage, including a controller and a sensor. The controller is used to control the lifting and rotation of a linear lifting drive device and a rotary drive device. The sensor is arranged on the inner side of a parking part. The sensor adopts an infrared sensor, which is used to detect the parking of the blue algae salvage equipment and can feed back the parking signal to the controller. A processor of an operation program is arranged in the controller. When the blue algae salvage equipment enters the parking part, the sensor in the parking part detects that the blue algae salvage equipment enters, and the sensor feeds back the detected signal to the controller. The controller first starts the linear lifting drive device, and the through hole controls the solenoid valve on the oil circuit of the telescopic oil cylinder 5 to lift the telescopic oil cylinder 5. After the telescopic oil cylinder 5 lifts the blue algae salvage equipment above the water surface, the controller controls the rotary drive motor 8 in the rotary drive device to rotate the blue algae salvage equipment above the road surface, and finally performs the unloading operation. A discharge port is arranged at the bottom of the blue algae salvage equipment, and the salvaged blue algae can be directly discharged to a truck through a leakage hole 21. After the unloading is completed, the blue algae salvage device can be put into the water again by the reverse operation process to perform a new round of salvage operation.
