Description

Technical Field

[0001] The utility model belongs to the technical field of microbial cultivation, and particularly relates to a lactic acid bacteria slow-release device suitable for treating blue algae rivers. Background Art

[0002] The pollution of rivers by excessive nutrients, especially nitrogen and phosphorus, will stimulate the massive growth of cyanobacteria. The massive reproduction of cyanobacteria will release a large amount of organic matter and metabolites, leading to the deterioration of water quality and having a negative impact on the aquatic ecosystem.

[0003] Since lactic acid bacteria can establish a competitive advantage over cyanobacteria in water bodies, through competition, lactic acid bacteria compete for the nutrients needed by cyanobacteria, thereby reducing the opportunities for cyanobacteria to obtain nutrients such as nitrogen and phosphorus, thereby inhibiting the growth of cyanobacteria. Therefore, spraying lactic acid bacteria onto the river surface through a spraying device is a commonly used method to control cyanobacteria in rivers.

[0004] However, spraying through a spraying device has the following disadvantages: on the one hand, since lactic acid bacteria are anaerobic bacteria, the spraying device sprays lactic acid bacteria on the surface of the river, and some lactic acid bacteria will inevitably come into contact with oxygen, affecting the effect of inhibiting cyanobacteria; on the other hand, since cyanobacteria grow quickly, the amount of lactic acid bacteria required is large, and the spraying device needs to be manually operated to re-spray every two or three days, which is time-consuming and labor-intensive. Therefore, a lactic acid bacteria slow-release device suitable for controlling cyanobacteria in rivers is proposed. Utility Model Content

DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the embodiments.

[0025] The following examples are intended to illustrate the present invention and are not intended to limit the scope of protection of the present invention. The conditions in the examples may be further adjusted according to specific conditions. Simple improvements to the method of the present invention based on the concept of the present invention fall within the scope of protection claimed by the present invention.

[0026] See also Figures 1 to 7 The utility model provides a lactic acid bacteria slow-release device suitable for treating blue algae in rivers, including a float 10; the float 10 is of detachable design, and is composed of a buoy 101 and a buoy 102. The buoy 101 and the buoy 102 are hemispherical and have a cavity inside, so that the buoy 101 and the buoy 102 can float on the water surface.

[0027] The sides of buoy 101 and buoy 2 102 that are close to each other are both provided with a placement groove 11 for placing the slow-release bag 12. The top of the placement groove 11 is connected to a line storage groove 111. The line storage groove 111 extends to the top of buoy 101 and buoy 2 102. A pulling ball 112 is provided on the top of the line storage groove 111. A connecting line 113 is provided in the line storage groove 111. The connecting line 113 is placed in the line storage groove 111 for daily storage. One end of the connecting line 113 is connected to the pulling ball 112, and the other end of the connecting line 113 is connected to the slow-release bag 12. By pulling the slow-release bag 12, the slow-release bag 12 can be pulled out of the placement groove 11, and by pulling the top pulling ball 112, the slow-release bag 12 can be pulled back to the placement groove 11.

[0028] The slow-release bag 12 is used to place pre-cultured rice bran, which is mixed with liquid lactic acid bacteria in a ratio of 1:6 of lactic acid bacteria to rice bran, presenting a semi-dry and semi-wet state. This step is mainly to provide a carbon source for lactic acid bacteria so that they can reproduce in the water body. The mixed rice bran is then placed in the slow-release bag 12 with stones at the bottom. Finally, the slow-release bag 12 is placed under buoy 101 and buoy 2 102 and placed in the water. By controlling the slow-release bag 12 in the middle of the river section, it is more conducive to the fish in the water to absorb lactic acid bacteria and improve the water environment. In addition, there is less dissolved oxygen in the water in the middle of the section, which can keep the lactic acid bacteria in an anoxic state, which is conducive to their growth and reproduction. It no longer requires manual time-consuming and labor-intensive multiple releases to the water surface.

[0029] Connection holes 13 for connection are provided on both sides of buoy 101 and buoy 2 102 , and thread 1 131 is provided inside the connection hole 13 .

[0030] A placement groove 2 14 for placing the telescopic rod 15 is provided on one side of buoy 101 close to buoy 2 102. The placement groove 2 14 is provided on both sides of the placement groove 11. Both ends of the telescopic rod 15 are provided with thread 2 151, which are threadedly connected with thread 1 131 in the connecting hole 13. By taking out the telescopic rod 15 in the placement groove 2 14 and inserting it into the connecting holes 13 on buoy 101 and buoy 2 102, buoy 101 and buoy 2 102 are connected according to the number of buoys required.

[0031] A slide groove 16 is provided on both sides of the bottom of the buoy 101, a spring 161 is provided in the slide groove 16, and a clamping plate 162 is provided at one end of the spring 161. One end of the spring 161 is connected to the slide groove 16, and the other end is connected to the clamping plate 162. By pressing the clamping plate 162, the clamping plate 162 compresses the spring 161 to slide in the slide groove 16.

[0032] A second slide groove 17 is provided in the first slide groove 16 . The second slide groove 17 is provided on a side away from the spring 161 . The second slide groove 17 is provided on a side wall of the first slide groove 16 . A clamping groove 171 is provided in the middle of the second slide groove 17 .

[0033] There are chutes 3 18 on both sides of the bottom of buoy 2 102. Chutes 3 18 are arranged at the position corresponding to chute 2 17. Chutes 3 18 are the same size as chute 2 17. There is a block 181 in chute 3 18. The width of block 181 is the same as that of slot 171, ensuring that block 181 can be inserted into chute 2 17 along slot 171. Block 2 182 is arranged at the end of block 181, and block 2 182 can be slidably connected with chute 16 and chute 2 17.

[0034] When buoy 101 and buoy 2 102 are spliced ​​to form the float 10, by inserting the block 2 182 into the slide 2 17, rotating the buoy 2 102, and making the buoy 2 102 rotate in the first direction, the block 2 182 moves along the slide 2 17 until it contacts the clamping plate 162, and the clamping plate 162 compresses the spring 161. When the block 2 182 disengages from the slide 2 17 and falls into the slide 1 16, the rotation of the buoy 2 102 is stopped. At this time, the buoy 2 102 rotates in the opposite direction to the first direction under the restoring force of the spring 161, so that the block 2 182 moves and is inserted into the slide 1 16 at the bottom of the slide 2 17. At this time, the block 181 is inserted into the clamping slot 171, so that the block 181 and the block 2 182 are clamped with the slide 16 and the clamping slot 171, thereby clamping the buoy 101 and the buoy 2 102.

[0035] When buoy 101 and buoy 2 102 need to be separated for use, just twist buoy 2 102 to rotate it in the first direction, so that block 181 and block 2 182 are disengaged from slide 16 and slot 171, and buoy 2 102 is disengaged from buoy 1 101.

[0036] The working principle and use process of the utility model are as follows: first, twist the buoy 2 102 to rotate the buoy 2 102 in the first direction, so that the block 181 and the block 2 182 are separated from the slide 16 and the slot 171, and then the buoy 2 102 is separated from the buoy 1 101 for use, and the telescopic rod 15 in the placement slot 14 is taken out, and the telescopic rod 15 is inserted into the connecting hole 13 on the buoy 101 and the buoy 2 102, and the buoy 101 and the buoy 2 102 are connected according to the number of buoys to be used. The slow-release bag 12 is connected in a row, and the pre-cultured rice bran is placed in a slow-release bag 12 with stones at the bottom. By pulling the slow-release bag 12, the slow-release bag 12 can be pulled out of the placement tank 11. Finally, the slow-release bag 12 is placed under the buoy 101 and the buoy 2 102 and placed in the water, so that the slow-release bag 12 is in the middle of the river section, which is conducive to the fish in the water to absorb lactic acid bacteria and improve the water environment. When the slow-release bag 12 is recovered, the buoy is retrieved and the pull ball 112 on the top of the buoy is pulled to pull the slow-release bag 12 back to the placement tank 11.
