Description

Technical Field

[0001] The present invention relates to the technical field of water area management, and in particular to a suspended algae control aeration device for water areas. Background Art

[0002] Algae will grow rapidly under suitable conditions of light, temperature, nutrients, etc., forming a "water bloom" phenomenon, which not only destroys the ecological balance of the water body, but also seriously affects the use function of the water body, such as drinking water safety, landscape water beauty, etc. Through aeration, oxygen in the air is dissolved into the water body, increasing the dissolved oxygen content of the water body. This helps to promote the growth and reproduction of beneficial microorganisms, thereby accelerating the decomposition and transformation of harmful substances in the water body. Algae are easy to reproduce in still water, and the water flow disturbance generated by the aeration device can effectively break the stagnant state of the water body and reduce the stable environment required for algae growth. At the same time, it can also transform the organic compounds in the water body into scum through the joint action of coagulants and flocculants, reducing the situation where organic compounds in the water body provide nutrients to algae.

[0003] The patent with the publication number of CN113697974A and the patent name of A water algae control aeration device points out that the existing water algae control aeration devices have the following technical defects: First, the aeration device converts pollutants into scum and accumulates on the liquid surface for a long time, which causes the scum to block the sunlight, restricting the growth of photosynthesis products at the bottom of the water, thereby destroying the ecological balance of the water area. At the same time, the photosynthesis products rot on a large scale due to lack of photosynthesis, further deteriorating the water quality. The aeration device realizes automatic aeration through the interaction between the buoyancy block, the buoyancy level gauge, the rope net and the straight guide rod. The purpose of starting the rope net to shrink inward is to achieve the effect of collecting the scum to the center, thereby solving the problem of limited growth of photosynthetic products on the bottom of the water caused by the scum blocking the sunlight, while maintaining the ecological balance of the water area and preventing further deterioration of the water quality. However, although the scum can be gathered through structures such as buoyancy blocks and rope nets, the rope nets with scum and gathered together will have a phenomenon of sinking of the entire device due to the relatively concentrated weight of the rope nets gathered together, which reduces the floating area. Therefore, the present application proposes a suspended algae control aeration device for water areas. Summary of the invention

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1: Figure 1As shown, the present application discloses a suspended algae control aeration device for water areas, comprising a carrying box 100, a plurality of aeration holes 800 are provided on the outside of the carrying box 100, an aerator 106 is installed inside the carrying box 100, a two-way air pump 102 is fixedly connected to the carrying box 100, an air outlet of the two-way air pump 102 is connected to a diverter box 101 through a delivery pipe, and the outside of the diverter box 101 is connected to an elastic telescopic network;

[0029] The elastic telescopic network includes a plurality of strip-shaped telescopic bags 103, a plurality of annular telescopic bags 104 and a plurality of four-way electric control valves 105. The plurality of strip-shaped telescopic bags 103 and the plurality of annular telescopic bags 104 are all equipped with water level sensors. The plurality of strip-shaped telescopic bags 103 are all connected to the outside of the diversion box 101. The annular telescopic bags 104 are connected to the plurality of strip-shaped telescopic bags 103 through a plurality of four-way electric control valves 105. The elastic telescopic network is used for when the aerator 106 performs algae control aeration and spreads flocculants into the water area, the algae and impurities inside the water area form scum, and the double water level sensors are used for the diversion box 101 to transfer the water level sensors to the water level sensors before the scum is formed. The airflow generated by the air pump 102 is respectively transmitted to multiple strip-shaped telescopic bags 103 and annular telescopic bags 104, and the air intake is controlled by a four-way electric control valve 105. When gas enters the strip-shaped telescopic bags 103 and the annular telescopic bags 104, they will expand, and after the expansion, a barrier net will be formed on the surface of the water area. When the barrier net is formed and scum enters the barrier net, the gas inside the strip-shaped telescopic bags 103 and the annular telescopic bags 104 is discharged to make the strip-shaped telescopic bags 103 and the annular telescopic bags 104 condense, thereby gathering the scum in the network to a designated position, thereby reducing the spread of scum and floating algae.

[0030] Specifically, during use, the staff places the entire device inside the designated water area. After placing the entire device inside the water area, the external control system remotely controls the two-way air pump 102 to start. After the two-way air pump 102 is turned on, the gas is transported to the inside of the diversion box 101 through the delivery pipe. After the gas is transported to the inside of the diversion box 101, it is diverted to the inside of multiple annular bellows 104 through the diversion box 101. When the gas is diverted to the inside of multiple annular bellows 104, the annular bellows 104 will expand. When the annular bellows 104 expands, it can drive the four-way electric The multiple annular bellows 104 connected by the four-way electric control valve 105 expand outward. During the outward expansion process, the staff can open or close the connection and closure between one or more four-way electric control valves 105 according to the needs, so as to control the gas flow to the inside of the strip bellows 103 and the annular bellows 104 at the designated position. When the gas flows into the strip bellows 103 and the annular bellows 104, the strip bellows 103 and the annular bellows 104 will expand and extend. After the strip bellows 103 and the annular bellows 104 expand and extend, a network can be formed. After the network is formed, the staff can point to the designated position. Flocculants are sprinkled inside the water area where the network is formed. After the flocculants are sprinkled, the flocculants react with organic matter inside the water area for a period of time to produce scum. The scum will float to the water surface by its own buoyancy. When the scum floats to the water surface, the strip-shaped telescopic bag 103 and the annular telescopic bag 104 can be partially lifted up. After the strip-shaped telescopic bag 103 and the annular telescopic bag 104 filled with gas are lifted up, a plurality of water level sensors (not shown in the figure) inside the strip-shaped telescopic bag 103 and the annular telescopic bag 104 will detect the change between themselves and the water level. After the change occurs, the water level sensor The device returns the information to the designated control system, thereby discharging the gas inside the strip-shaped telescopic capsule 103 and the annular telescopic capsule 104. After the gas inside the strip-shaped telescopic capsule 103 and the annular telescopic capsule 104 is discharged, the strip-shaped telescopic capsule 103 and the annular telescopic capsule 104 will produce condensation. When the strip-shaped telescopic capsule 103 and the annular telescopic capsule 104 produce condensation, the scum inside the network can be retracted inwards, thereby aggregating the scum and gathering it to the designated position, thereby avoiding the problem of scum blocking sunlight and limiting the growth of photosynthetic products on the bottom of the water, while maintaining the ecological balance of the water area and preventing further deterioration of the water quality.

[0031] Furthermore, a bleed valve 901 is installed on the outside of the diverter box 101, and the gas can be discharged from the outside of the diverter box 101 through the bleed valve 901. The gas inside the strip-shaped telescopic bag 103 and the annular telescopic bag 104 can also be sucked out by reversely starting the two-way air pump 102. After continuously sucking out the gas, the strip-shaped telescopic bag 103 and the annular telescopic bag 104 can be further condensed together.

[0032] like Figure 6 As shown, an inclined nozzle 900 is integrally formed inside the aeration hole 800. The inclined nozzle 900 is obliquely fixedly connected to the inside of the aeration hole 800, and the air outlet of the inclined nozzle 900 faces the water surface.

[0033] Specifically, during use, the aerator 106 is started to aerate the water body. During the aeration process, the oxygen transported by the aerator 106 to the water body will first enter the interior of the carrier box 100 and be transmitted outward through the aeration holes 800. The inclined nozzle 900 connected inside the aeration holes 800 can transport the transported gas obliquely upward to the water surface, so that the force generated by the aerator 106 when transporting the airflow is downward, thereby reducing the phenomenon that the water flow is ejected parallel to the water flow, causing the carrier box 100 to float on the water surface and sway left and right.

[0034] like Figure 1 and Figure 6 As shown, during use, the two-way air pump 102 can also deliver gas to the inside of the delivery pipe 108, and the gas is delivered to the inside of the outer floating bladder 107 through the delivery pipe 108. When the gas enters the inside of the outer floating bladder 107, the outer floating bladder 107 will expand. The expanded outer floating bladder 107 provides buoyancy to the carrying box 100 and the aerator 106, keeping the carrying box 100 and the aerator 106 floating on the water.

[0035] Furthermore, during use, the strip-shaped telescopic bladders 103 and the annular telescopic bladders 104 that expand and form a network can further increase the overall buoyancy because there is gas inside. The strip-shaped telescopic bladders 103 and the annular telescopic bladders 104 that form a network can ensure that the supporting box 100 will not tip over, and during long-term use, the algae on the water surface can be cleaned regularly, and the presence of algae and impurities can be further reduced as a whole in conjunction with the aerator 106.

[0036] like Figure 1 and Figure 6 As shown, a telescopic rod 600 is fixedly connected to the carrying box 100 , and an output shaft of the telescopic rod 600 is fixedly connected to the bottom of the diverter box 101 .

[0037] Specifically, when in use, when it is necessary to collect the net or mark the center, the telescopic rod 600 can be started to drive the diversion box 101 and multiple annular telescopic bags 104 to move upward at the center, so that the staff can determine the center position to collect the net or disassemble it.

[0038] like Figure 5As shown, a first threaded tube 500 is integrally formed at one end of the strip-shaped bellows 103 and the annular bellows 104, threaded holes 501 are provided at two of the air inlet and outlet ports of the four-way electric control valve 105, the first threaded tube 500 is threadedly connected to the inside of the threaded hole 501, the other two air inlet and outlet ports of the four-way electric control valve 105 are integrally formed with a second threaded tube 502, an internal threaded section 503 is integrally formed at the other end of the strip-shaped bellows 103 and the annular bellows 104, and the second threaded tube 502 is threadedly connected to the inside of the internal threaded section 503.

[0039] Specifically, during use, the staff can freely assemble the annular telescopic bag 104, the strip telescopic bag 103 and the four-way electric control valve 105 according to the shape of the water pond, and thread the first threaded tube 500 into the interior of the threaded hole 501, so that one end of the annular telescopic bag 104 or the strip telescopic bag 103 can be connected to the four-way electric control valve 105, and the other end of the other strip telescopic bag 103 or the annular telescopic bag 104 can be threaded into the interior of the internal thread section 503 through the second threaded tube 502, so that the other strip telescopic bag 103 or the annular telescopic bag 104 can be connected to the four-way electric control valve 105.

[0040] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to the prior art, in the present application, a gap network is formed as a whole through the elastic strip-shaped telescopic capsule 103 and the annular telescopic capsule 104. After the gap network is formed, the floating algae on the water surface can be gathered and pulled to a designated position. At the same time, when the flocculant is sprinkled to form scum, the scum can be collected and cleaned toward the center. Moreover, when the strip-shaped telescopic capsule 103 and the annular telescopic capsule 104 are used, the overall weight is lighter, and the weight does not increase too much after gathering toward the center. Moreover, when gathering toward the center, it is only necessary to discharge the gas inside the strip-shaped telescopic capsule 103 and the annular telescopic capsule 104, and the degree of contraction and extension is higher.

[0041] Embodiment 2: Considering that the airbag net group needs to gather the scum together when it retracts, but because the airbag net group needs to be exhausted when it condenses and gathers the scum, this causes the edge of the annular telescopic bag 104 to be warped due to exhaust. Once the exhaust causes the edge to warp, some floating algae and scum will be skipped, and a good collection effect cannot be achieved. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically:

[0042] like Figure 2-Figure 3As shown, the outside of the strip-shaped telescopic bladder 103 and the annular telescopic bladder 104 are both integrally formed with a lower expansion claw 200, and the lower expansion claw 200 includes an outer expansion claw bladder 201 and an inner expansion claw bladder 202, the outer expansion claw bladder 201 and the inner expansion claw bladder 202 are both integrally formed on the outside of the strip-shaped telescopic bladder 103 and the annular telescopic bladder 104, the inner expansion claw bladder 202 is located inside the outer expansion claw bladder 201, an air intake cavity 203 is formed between the inner expansion claw bladder 202 and the outer expansion claw bladder 201, the air intake cavity 203 is connected to the annular telescopic bladder 104, a reflux blocking structure is connected between the air intake cavity 203 and the annular telescopic bladder 104, a plurality of elastic through-membrane tubes 204 are integrally formed on the outside of the outer expansion claw bladder 201 and the inner expansion claw bladder 202, and the elastic through-membrane tubes 204 are connected to the inside of the inner expansion claw bladder 202.

[0043] Specifically, during use, when gas is transported to the inside of the strip-shaped telescopic bag 103 and the annular telescopic bag 104, part of the gas will be transported to the inside of the air intake cavity 203. When the gas is transported to the air intake cavity 203, the outer expansion claw bag 201 and the inner expansion claw bag 202 will extend and expand due to the support of the gas. When the extension and expansion occur, the multiple lower expansion claws 200 will form a claw shape as a whole. By forming the claw-shaped lower expansion claws 200, the floating algae can be further hooked up when the overall condensation produces gathered floating algae, thereby strengthening the cleaning of floating algae by the multiple annular telescopic bags 104 and the strip-shaped telescopic bags 103. When the multiple lower expansion claws 200 expand to form claws, water will flow into the inside of the inner expansion claw bag 202 through the elastic through-membrane tube 204. When the water flows into the inside of the inner expansion claw bag 202, the overall deadweight will be increased, thereby ensuring that the annular telescopic bag 104 will not warp during the condensation of the strip-shaped telescopic bag 103 and the annular telescopic bag 104.

[0044] like Figure 8 As shown, the backflow blocking structure includes a semi-rigid bearing section 700, which is integrally formed on the outside of the annular bellows 104. The hardness of the semi-rigid bearing section 700 is greater than that of the annular bellows 104. A plurality of through holes 701 are provided on the outside of the semi-rigid bearing section 700. The through holes 701 are respectively connected to the air intake cavity 203 and the inside of the annular bellows 104. A plurality of one-way valve plates 702 are integrally formed on the bottom of the semi-rigid bearing section 700. The outer wall diameter of the one-way valve plate 702 is greater than the inlet and outlet aperture of the through hole 701. The one-way valve plate 702 is located inside the air intake cavity 203.

[0045] Furthermore, when the floating algae and scum are being condensed and gathered, the gas inside the annular telescopic bag 104 will enter the interior of the air intake cavity 203 through the through hole 701. When the gas continues to enter the interior of the air intake cavity 203 through the through hole 701, the outer expansion claw bag 201 and the inner expansion claw bag 202 will expand and extend. In order to prevent the gas inside the air intake cavity 203 from being discharged along with the exhaust stroke during the condensation process, the airflow can be returned to the interior of the annular telescopic bag 104 through the one-way valve plate 702. The one-way valve plate 702 is elastic and will only open when gas is continuously transported from the annular telescopic bag 104 to the through hole 701. When there is no continuous external gas transport, the through hole 701 will be closed by its own elasticity.

[0046] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to embodiment one, in the present embodiment, gas enters the air intake cavity 203 and the outer expansion claw bag 201 and the inner expansion claw bag 202 are expanded, which can assist in the gathering of scum and reduce the phenomenon of scum gathering and residue. At the same time, the setting of the external elastic through-membrane tube 204 can allow water to flow into the interior of the inner expansion claw bag 202, and the overall weight is increased to form a counterweight, so as to ensure that the airbag net group will not warp during the exhaust and condensation process of the airbag net group, thereby further improving the efficiency of scum gathering.

[0047] Embodiment 3: Considering that when the airflow continues to enter the air inlet cavity 203, the inner expansion claw bag 202 and the outer expansion claw bag 201 will continue to expand due to the entry of gas, and the internal space of the air inlet cavity 203 will gradually increase after continuous expansion. When the internal space gradually increases, the elastic through-membrane tube 204 will continue to transport water to the internal space of the inner expansion claw bag 202, resulting in an increase in the weight of the air inlet cavity 203. When the weight of the air inlet cavity 203 continues to increase, it will cause the entire air bag net group to sink into the water under the weight of the lower expansion claw 200, and it will not be able to play a role in gathering the scum on the water surface. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically:

[0048] like Figure 3-Figure 4 As shown, a plurality of air outlet holes 300 are provided on the outside of the outer expansion claw bag 201, and the air outlet holes 300 are in a closed state under normal conditions. When gas continues to enter the air intake cavity 203 to cause the outer expansion claw bag 201 and the inner expansion claw bag 202 to expand and extend, the air outlet holes 300 will open due to the extension of the outer expansion claw bag 201 and the inner expansion claw bag 202.

[0049] Specifically, during use, in order to prevent the gas from continuously filling into the interior of the air intake cavity 203 and causing excessive expansion of the inner expansion claw bag 202 and the outer expansion claw bag 201, when the outer expansion claw bag 201 and the inner expansion claw bag 202 expand to a specified state, the air outlet nozzle 300 located on the outer wall of the outer expansion claw bag 201 and connected to the air intake cavity 203 will open, thereby discharging the gas stored in the air intake cavity 203 to the outside, and after being discharged to a specified degree, the outer expansion claw bag 201 and the inner expansion claw bag 202 will be in a condensed state due to the reduction of the gas inside the air intake cavity 203, thereby shrinking. In the shrinking state, the air outlet nozzle 300 located outside the outer expansion claw bag 201 will be closed again to prevent a large amount of gas from flowing out.

[0050] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to the second embodiment, in the present embodiment, through the setting of the air outlet nozzle 300, only when excessive gas enters the air inlet cavity 203 and the excessive gas causes the outer expansion claw capsule 201 and the inner expansion claw capsule 202 to over-extend and expand, the air outlet nozzle 300 will open due to the expansion and extension of the outer expansion claw capsule 201, and the greater the expansion degree of the outer expansion claw capsule 201, the larger the opening of the air outlet nozzle 300. When the air outlet nozzle 300 opens, excess gas can be discharged from the air inlet cavity 203, reducing the amount of gas in the air inlet cavity 203; when the amount of gas is reduced, the outer expansion claw capsule 201 and the inner expansion claw capsule 202 will naturally shrink; in the case of natural shrinkage, the air outlet nozzle 300 will return to the original closed state again, preventing a large amount of gas from escaping, thereby forming a control over the overall expansion degree of the inner expansion claw capsule 202 and the amount of water entering the interior, reducing the situation where the inner expansion claw capsule 202 is over-inflated and weighs too much and causes sinking.

[0051] Embodiment 4: Considering that the existence of the gas outlet spray hole 300 can timely limit the weight of the lower expansion claw 200, the gas outlet spray hole 300 is always a through hole, and the gas will always leak from the gas outlet spray hole 300. If the salvaging time is long and the gas is not filled into the air bag net group in time, the gas will still leak through the gas outlet spray hole 300, causing the lower expansion claw 200 to condense. When the lower expansion claw 200 condenses, the storage space inside the inner expansion claw bag 202 will become smaller, thereby squeezing out the water flow, and it is impossible to form a counterweight and salvage situation. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically:

[0052] like Figure 4As shown, the air outlet nozzle 300 is square in shape as a whole and the aperture of the air inlet end is larger than that of the air outlet end. A magnetic attraction sheet 400 is integrally formed on the inner upper wall of the square air outlet nozzle 300, and an iron attraction sheet 401 is integrally formed on the inner lower wall of the square air outlet nozzle 300.

[0053] Specifically, during use, the square air outlet hole 300 is in a closed fitting state in the initial state. The air outlet hole 300 in the closed fitting state will ensure that the air outlet hole 300 is in a completely closed state through the adsorption between the magnetic suction sheet 400 and the iron adsorption sheet 401 to avoid gas leakage. When the gas enters the air inlet cavity 203, the outer expansion claw capsule 201 expands and extends, which will cause the extension of the outer expansion claw capsule 201 to drive the magnetic suction sheet 400 and the iron adsorption sheet 401 to separate. 0 and the iron adsorption sheet 401 are separated, and the gas outlet nozzle 300 will gradually open as the outer expansion claw bag 201 extends. When the gas outlet nozzle 300 gradually opens, the gas can be discharged, and the aperture of the air inlet end of the gas outlet nozzle 300 is larger than the aperture of the air outlet end, so that the gas outlet nozzle 300 will not have a large outlet opening and a large amount of spraying, and when the outer expansion claw bag 201 shrinks, the magnetic sheet 400 and the iron adsorption sheet 401 will be re-adsorbed and attached together, thereby closing the gas outlet nozzle 300 to prevent gas leakage.

[0054] The technical scheme in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to the third embodiment, in the present embodiment, there are magnetic suction sheets 400 and iron suction sheets 401 on the upper and lower side walls of the square-shaped air outlet nozzle 300 respectively, and when the lower expansion claw 200 is not expanded to a specified degree, the magnetic suction sheet 400 and the iron suction sheet 401 will produce adsorption to close the air outlet nozzle 300, and only when the lower expansion claw 200 is expanded to a specified degree, the expanded outer expansion claw capsule 201 will separate the magnetic suction sheet 400 and the iron suction sheet 401, thereby discharging the gas inside the air intake cavity 203, thereby controlling the gas volume inside the air intake cavity 203 and the flow rate of water inside the inner expansion claw capsule 202, ensuring that the lower expansion claw 200 can form a specified state and counterweight, and will not sink into the water, thereby avoiding the phenomenon that the lower expansion claw 200 cannot assist in gathering scum and floating algae.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
