Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ecological floating island restoration, in particular to a fish habitat restoration system. BACKGROUND

[0002] In the fish habitat restoration system, ecological floating islands are widely used. Ecological floating islands are commonly used restoration systems for water purification. Aquatic plants on ecological floating islands, such as Acorus calamus, Canna indica, and Oenanthe javanica, have root systems that extend deep into the water, directly absorbing excess nitrogen, phosphorus, and other eutrophication substances in the fish pond, thereby playing a role in restoring fish habitats. The current fish habitat restoration system is not convenient for automatically controlling the expansion of plant root systems. Typically, a mesh structure tray is used to support coconut fiber substrate to prevent substrate leakage, which restricts the growth of plant root systems. In addition, it is not convenient to protect plants from being over-eaten by fish. Aquatic plant root systems contain starch and soluble sugar, which are natural bait for omnivorous fish. When the ecological floating island is subjected to strong wind or water exchange, although the floating island can adapt to the water surface, the plant root systems are well developed and can root in the bottom or slope of the fish pond. When the ecological floating island falls or displaces beyond the standard, the root systems are easily pulled and the plants are damaged.

[0003] Therefore, we propose a fish habitat restoration system. SUMMARY

[0034] The repair traction piece 1 further comprises a water adding pipe 104, a plant supporting plate 105, an expansion hole 106 and a sliding installation cylinder 107, the annular floating box 103 is fixedly installed with the water adding pipe 104; the water adding pipe 104 is externally connected with a water pump; the fixed ring 101 is fixedly installed with the plant supporting plate 105, and the plant supporting plate 105 is provided with six rows of arc-shaped slot holes; the plant supporting plate 105 is provided with six rows of expansion holes 106; the expansion holes 106 are used for facilitating the root system to pass through; the plant supporting plate 105 is fixedly installed with the sliding installation cylinder 107, and the middle part of the sliding installation cylinder 107 is a hexagonal hole; the root system expansion piece 2 comprises a lifting column 201, a baffle 202 and a limiting column 203, the lifting column 201 is a hexagonal column; the lifting column 201 is slidingly inserted into the sliding installation cylinder 107; the bottom of the lifting column 201 is fixedly installed with six baffles 202, and the six baffles 202 respectively cover the six rows of expansion holes 106; the lifting column 201 is fixedly installed with the limiting column 203; the limiting column 203 is located above the sliding installation cylinder 107; the side of the lifting column 201 is provided with a thimble; the positioning piece 3 comprises a pulling and inserting shaft 301 and a traction rope 302, the pulling and inserting shaft 301 is slidingly inserted into the sliding installation cylinder 107; the end of the pulling and inserting shaft 301 is inserted into the thimble provided on the side of the lifting column 201; the pulling and inserting shaft 301 is sleeved with a tension spring, and the tension spring on the pulling and inserting shaft 301 is connected between the pulling and inserting shaft 301 and the sliding installation cylinder 107; the pulling and inserting shaft 301 is fixedly installed with the traction rope 302;The traction rope 302 is used to pull the plug-and-plant shaft 301 by hand, and the root system expansion piece 2 is matched with the repair traction piece 1 to facilitate the expansion of the root system through the expansion hole 106. The expansion hole 106 has a larger hole diameter, which can reduce the rooting resistance and cooperate with the positioning control of the positioning piece 3. Because the plant supporting plate 105 needs to be planted with plants, it is necessary to lay coconut fiber substrate, so the width of the through slot on the plant supporting plate 105 cannot be too large, otherwise it is easy to cause the coconut fiber substrate to leak. By using the baffle 202, after the plant root system is distributed and grows, the roots are intertwined with each other, and the coconut fiber substrate is integrated.

The coconut fiber is laid on the plant supporting plate 105. At present, coconut fiber is usually used as the substrate because the coconut fiber itself is filamentous, which can facilitate the laying of the hydroponic plant tray to form a whole, increase stability, and improve wind resistance. At the same time, the coconut fiber is taken from the coconut shell, and the main component is cellulose, which will not cause pollution. Pulling the traction rope 302 drives the plug-and-plant shaft 301 to pull out from the lifting column 201. The lifting column 201 and the baffle 202 will fall under the action of gravity. At this time, the baffle 202 no longer blocks the expansion hole 106. At this time, the coconut fiber is distributed by the root system, and the coconut fiber is filamentous. At this time, the coconut fiber will not leak. At this time, the expansion hole 106 with a larger hole diameter can facilitate the root system to pass through. As the root system grows, it will also fill the expansion hole 106, which is convenient for distribution in the water body to realize hydroponics and provide nutrients, and gradually replace the coconut fiber.

[0037] The working principle of the embodiment is as follows: first, the structure is placed in a fish pond, the fixing ring 101 is arranged at the bottom of the fish pond and weighted, the lengths of the four limiting ropes 102 are set according to requirements, the coconut fiber matrix is laid on the plant supporting plate 105, at this time, the baffle 202 blocks the bottom of the expansion hole 106, at this time, the coconut fiber matrix will not leak, but only play a wetting role through the six rows of arc-shaped slot holes on the plant supporting plate 105, with the growth of the plants planted on the coconut fiber on the plant supporting plate 105, when the plant roots are intertwined with each other, the artificial can periodically observe the distribution of the plant roots in the coconut fiber, and after the coconut fiber is distributed in the coconut fiber matrix and the coconut fiber is in an integral state, the artificial manually pulls the traction rope 302 to drive the pulling shaft 301 to pull out from the lifting column 201, and the lifting column 201 and the baffle 202 will fall under the action of the weight, at this time, the baffle 202 no longer blocks the expansion hole 106, at this time, the coconut fiber is distributed by the roots, and the coconut fiber is in a silk state, at this time, the coconut fiber will not leak excessively, at this time, the expansion hole 106 with a larger hole diameter can facilitate the roots to pass through, and the roots will also fill the expansion hole 106, so as to facilitate the distribution in the water body to realize water culture and provide culture material; when the normal water level and the environment are stable, the one-piece fitting plate 603 can be elastically fitted to the rotating ring 503 under the pulling of the tension spring on the one-piece correction pushing shaft 602, so as to improve the stability of the annular floating box 103, once the environment wind is too large, the moving pressure of the annular floating box 103 is greater than the elastic force of the tension spring on each correction pushing shaft 602 in the moving direction, at this time, when the water surface displacement of the annular floating box 103 exceeds the standard, each fitting plate 603 on the side in the moving direction is squeezed and retracted, and the retraction amount exceeding the standard will squeeze the micro switch 606, the tension spring arranged on the telescopic shaft 605 can ensure that the micro switch 606 still has a certain elastic displacement amount after being squeezed, when any micro switch 606 is squeezed, the driving motor 501 is electrified, the lower rotary rod 502 and the outer rotary rod 504 are driven to rotate, the blades on the lower rotary rod 502 and the outer rotary rod 504 cut the roots outside the protective net cylinder 401 and the lower flow-through plate 403, so as to avoid the roots from being pulled by the soil, and the same reason is that once the water in the fish pond is excessively discharged, the annular floating box 103 will adapt to the water surface to drop, drive the rotating ring 503 to drop and squeeze the falling detection plate 604, at this time, the fitting plate 603 will retract and approach to squeeze the micro switch 606, and the driving motor 501 is controlled to start to cut the roots, so as to avoid the roots rooted in the fish pond wall from being excessively pulled when the annular floating box 103 drops;

[0038] When water needs to be added after the fish tank is drained, the lower rotary rod 502 and the outer rotary rod 504 are driven to rotate by starting the driving motor 501, and the brush on the lower rotary rod 502 and the outer rotary rod 504 brushes the protective screen cylinder 401 and the lower flow-through plate 403. At this time, the water pump connected to the water adding pipe 104 can be started to supply water and add water, realizing the water adding work. When used normally, the protective screen cylinder 401 and the lower flow-through plate 403 also play a role in preventing the plant head from being eaten outside the plant root system, ensuring that fish can only eat the plant end.
