Description

Technical Field

[0001] The utility model relates to the technical field of concrete artificial fish reefs, in particular to a concrete artificial fish reef applicable to soft soil foundations. Background Technique

[0002] A fish reef is a kind of reef formed by the accumulation of fish bones or waste discharged by fish over the years. It is mainly formed in places such as the ocean and lakes. It is also one of the habitats of fish and plays an important role in maintaining the marine ecological balance.

[0003] An artificial fish reef is a structure artificially set in the sea. Its purpose is to improve the marine ecological environment, create a good environment for marine organisms to inhabit, provide a place for fish and the like to breed, grow, forage and take shelter from enemies, and achieve the purpose of protecting, increasing and improving the fishing yield. Usually, suitable sea areas are selected and stones, trees, waste ships and vehicles, waste tires and precast reinforced concrete blocks are put in to form artificial reefs, which can attract and increase the resources of demersal and mid-upper layer fish with sedentary and migratory habits, and form a relatively stable artificial fish reef fishing ground.

[0004] However, when the existing concrete artificial fish reefs are used in soft soil foundation sea areas, they cannot prevent siltation and resist settlement well. At the same time, in positions with relatively large wind and waves, they are easily affected by the rolling of tides in uncertain directions and are prone to tipping and sliding, affecting the overall use. Therefore, they do not meet the existing needs. For this reason, we propose a concrete artificial fish reef applicable to soft soil foundations. Content of the Utility Model

[0005] The purpose of the utility model is to provide a concrete artificial fish reef applicable to soft soil foundations, so as to solve the problems that when the concrete artificial fish reefs are used in soft soil foundation sea areas, they cannot prevent siltation and resist settlement well, and at the same time, in positions with relatively large wind and waves, they are easily affected by the rolling of tides in uncertain directions and are prone to tipping and sliding, affecting the overall use as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A concrete artificial fish reef applicable to soft soil foundations, including an artificial fish reef main body. Fixing plates are fixed on four sides of the artificial fish reef main body. The four fixing plates are divided into two lengths. The two longer fixing plates are symmetrical to each other, and the two shorter fixing plates are symmetrical to each other. Reinforcing plates are fixed at the bottom ends of the four fixing plates. Receiving holes are arranged inside both ends of the reinforcing plates. Reinforcing insertion rods are slidably installed inside the receiving holes. The other ends of the reinforcing insertion rods are provided with round holes. Pressure springs are arranged inside the round holes. Both ends of the pressure springs are respectively fixed to the inner wall of the reinforcing plate and the inner end of the round hole.

[0007] Preferably, a fixing block is fixed inside the artificial fish reef main body. A guiding hole penetrates through the fixing block, and a guiding rod is slidably inserted into the guiding hole.

[0008] Preferably, there is a height difference between the bottom end of the guiding rod and the bottom surface of the artificial fish reef main body. The top end of the guiding rod is fixed with a lifting connecting plate, which is bent at 90 degrees and has connecting rods fixed to the bottoms of both ends.

[0009] Preferably, protective plates are fixed to the bottom ends of both connecting rods. One end of the protective plate is bent downward at 90 degrees and fits against the end face of the reinforcing plate, and the protective plate is in sliding contact with the end of the reinforcing plate.

[0010] Preferably, a counterweight block is arranged below the lifting connecting plate, and the counterweight block is fixed to the outer side of the upper end of the guiding rod.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. After the artificial fish reef main body reaches the seabed, the guiding rod first contacts the seabed and drives the protective plate to move upward, causing the protective plate to be misaligned with the end of the reinforcing plate. The compression spring elastically resumes and pushes the reinforcing insertion rod out of the reinforcing plate. The ejected reinforcing insertion rod is obliquely inserted into the seabed until the bottom surface of the artificial fish reef main body contacts the seabed. The eight obliquely inserted reinforcing insertion rods into the seabed reinforce the bottom of the artificial fish reef main body, preventing the artificial fish reef main body from shifting in position or rolling on the seabed due to ocean undercurrents, and ensuring the stability and normal use of the artificial fish reef main body.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] As Figures 1 to 4 shown, a concrete artificial fish reef applicable to soft soil foundation, fixing plates 2 are fixed on four sides of the artificial fish reef main body 1. The four fixing plates 2 are divided into two lengths. The two longer fixing plates 2 are symmetrical to each other, and the two shorter fixing plates 2 are symmetrical to each other. Reinforcing plates 3 are fixed at the bottom ends of the four fixing plates 2. Receiving holes 10 are provided inside both ends of the reinforcing plate 3. Reinforcing insertion rods 11 are slidably installed inside the receiving holes 10. The other end of the reinforcing insertion rod 11 is provided with a round hole, and a pressure spring 12 is provided inside the round hole. The two ends of the pressure spring 12 are respectively fixed to the inner wall of the reinforcing plate 3 and the inner end of the round hole. The artificial fish reef main body 1 is placed into the sea. After the bottom surface of the artificial fish reef main body 1 contacts the seabed, the pressure spring 12 elastically restores and pushes the reinforcing insertion rod 11 out of the inner part of the end of the reinforcing plate 3, so that the inclined reinforcing insertion rod 11 is inserted into the seabed to reinforce the artificial fish reef main body 1.

[0020] Fixing blocks 7 are fixed inside the artificial fish reef main body 1. Guide holes penetrate through the fixing blocks 7. Guide rods 5 are slidably inserted inside the guide holes. There is a height difference between the bottom end of the guide rod 5 and the bottom surface of the artificial fish reef main body 1. The top end of the guide rod 5 is fixed with a lifting connecting plate 9. The lifting connecting plate 9 is bent at a right angle and connecting rods 6 are fixed to the bottoms of both ends. The guide rod 5 contacts the seabed before the artificial fish reef main body 1, and drives the lifting connecting plate 9 and the connecting rods 6 to slide upward after contacting the seabed until the bottom surface of the artificial fish reef main body 1 contacts the seabed.

[0021] Protecting plates 4 are fixed to the bottom ends of the two connecting rods 6. One end of the protecting plate 4 is bent downward at a right angle and fits the end face of the reinforcing plate 3. The protecting plate 4 is in sliding contact with the end of the reinforcing plate 3. The receiving holes 10 at the ends of the reinforcing plate 3 are closed by using the protecting plate 4, ensuring that the reinforcing insertion rod 11 will not pop out of the inside of the reinforcing plate 3 when the guide rod 5 does not contact the seabed and moves upward.

[0022] A counterweight 8 is provided below the lifting connecting plate 9. The counterweight 8 is fixed to the outer side of the upper end of the guide rod 5. The weight of the guide rod 5 is increased by using the counterweight 8 to ensure that the guide rod 5 will not slide upward during the process of the artificial fish reef main body 1 sinking to reach the seabed.

[0023] Working principle: When in use, place the prepared artificial reef main body 1 into the sea and ensure that the four guide rods 5 face the sea surface. Then release the artificial reef main body 1. Under the action of gravity, the artificial reef main body 1 sinks into the sea. When the artificial reef main body 1 sinks into the sea and reaches the seabed, the bottom ends of the four guide rods 5 first come into contact with the seabed. At this time, the four guide rods 5 are blocked by the seabed and stop moving, while the artificial reef main body 1 continues to sink. At this time, the guide rods 5 slide upward inside the fixed block 7, and the fixed block 7 drives the lifting connecting plate 9, the connecting rod 6, and the protection plate 4 to move upward. After the protection plate 4 moves upward, it separates from the end of the reinforcement plate 3. At this time, the port of the receiving hole 10 is opened, and the pressure spring 12 compressed by the reinforcement insertion rod 11 and the reinforcement plate 3 restores elastically. After elastic restoration, the pressure spring 12 ejects the reinforcement insertion rod 11 inclined to the seabed plane from inside the reinforcement plate 3. The ejected reinforcement insertion rod 11 is inserted into the seabed obliquely until the bottom surface of the artificial reef main body 1 comes into contact with the seabed. The eight reinforcement insertion rods 11 inclined and inserted into the seabed reinforce the bottom of the artificial reef main body 1, preventing the artificial reef main body 1 from shifting in position or rolling on the seabed due to ocean undercurrents, and ensuring the stability and normal use of the artificial reef main body 1.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description.
