Description

Technical Field

[0001] This utility model relates to the field of river duckweed barrier technology, specifically to a barrier cable float that can be used for fish spawning. Background Technology

[0002] In waters with insufficient hydrodynamics, nutrient concentrations rise due to various factors such as external input or sediment release, often leading to the growth of duckweed. Duckweed is a floating plant that absorbs nutrients from the water through its rhizoids. Duckweed has a strong water purification capacity, rapidly absorbing eutrophic substances such as nitrogen and phosphorus from the water, thus purifying the water quality.

[0003] Duckweed floats on the water surface, blocking sunlight from entering the water body, which may affect the growth and development of submerged plants, reduce the dissolved oxygen content in the water, and thus affect the normal life of some fish and benthic animals in the water. The spread of duckweed will affect the aesthetics of the landscape, so it is necessary to stop the duckweed.

[0004] Existing methods of blocking duckweed include nets or floating rafts. While nets and floating rafts can effectively block duckweed, they are limited in function, do not facilitate fish reproduction, and pollute the environment when abandoned as they sink in the water. They are also difficult to degrade and require improvement. Utility Model Content

[0005] (I) Technical problems to be solved

[0006] The technical problem to be solved by this utility model is to overcome the above difficulties and provide a barrier rope float that can block duckweed on the water surface, decomposes quickly after being discarded and will not pollute the environment, and can provide a breeding environment for fish to spawn.

[0007] (II) Technical Solution

[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a barrier cable float for fish spawning, comprising a barrier cable made of first reed stalks, wherein a plurality of reed balls made of second reed stalks are evenly arranged on the barrier cable;

[0009] The reed ball is filled with palm leaves;

[0010] Both ends of the barrier cable are equipped with fixing ropes, and the other end of the fixing ropes is equipped with ground nails inserted into the riverbank.

[0011] As an improvement, the barrier cable is fitted with several first fixing rings for binding the first reed stalks.

[0012] As an improvement, the barrier cable is provided with a second fixing ring at the end near the reed ball to bind the first reed stalk.

[0013] As an improvement, the palm leaf extends to the outside of the reed ball.

[0014] (III) Beneficial Effects

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] 1. The barrier cable and reed ball are made by binding the first reed stalk and the second reed stalk together. They float on the water surface and can block duckweed. They decompose quickly after being discarded and will not pollute the environment.

[0017] 2. The reed ball is filled with palm leaves extending to the outside of the reed ball. The palm leaves float in the water and can provide a carrier for fish reproduction.

[0018] 3. The fixing rope and ground nails can be used to fix the device. Attached Figure Description

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] Example 1

[0026] Combined with appendix Figure 1-4A barrier cable float for fish spawning includes a barrier cable 2 made of first reed stalks 1 bound together, and several reed balls 4 made of second reed stalks 3 evenly arranged on the barrier cable 2; the reed balls 4 are filled with palm leaves 5; both ends of the barrier cable 2 are provided with fixing ropes 6, and the other end of the fixing ropes 6 is provided with ground nails 7 inserted into the riverbank.

[0027] Ground nails 7 are inserted into the embankment on the riverbank to fix the device. The barrier cable 2 and the reed ball 4 float on the river surface, with half of them on the water and the other half on the water surface, to block the duckweed. The palm leaves 5 extend to the outside of the reed ball 4, allowing fish to lay their eggs on it.

[0028] The barrier cable 2 is fitted with several first fixing rings 8 to bind the first reed stalk 1, which can fix the first reed stalk 1.

[0029] The barrier cable 2 is provided with a second fixing ring 9 at one end near the reed ball 4 to tie the first reed stalk 1, which can fix the first reed stalk 1 and cooperate with the second reed stalk 3 to form a reed ball.

[0030] The palm leaf 5 extends to the outside of the reed ball 4 and is immersed in water to provide a carrier for fish to lay their eggs.

[0031] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions, alterations, deletions of some features, additions of features, or recombinations of features to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the innovative principles of the present invention shall still fall within the scope of the technical solutions of the present invention.
