Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of marine ecological environment restoration, in particular to a self-sediment-discharging artificial fish reef. BACKGROUND

[0002] An artificial fish reef refers to a structure placed in the marine water by human beings, aiming to improve the marine ecological environment, promote the recovery of fishery resources, protect biodiversity and support the sustainable development of fishery.

[0003] The artificial fish reef comprises a plurality of shelter channels or shelter holes. Due to the habitat of fish, the fish will excrete in the artificial fish reef. The excrement is mixed with some solid particles. In addition, some fish have the habit of swallowing and spitting the fine sand or particles on the seabed. Therefore, these fine solid substances are easy to form sediments in the fish reef. Over time, these sediments are easy to block the shelter holes or shelter channels, or gradually block those shelter channels at the bottom of the fish reef, which is not conducive to the discharge of sediments. The actual use effect of the fish reef is reduced, and the service life thereof is reduced. SUMMARY

[0004] The present application aims to provide a self-sediment-discharging artificial fish reef, which is used to solve the problem that the fish reef in the prior art is not conducive to the discharge of sediments.

[0005] The technical solution adopted by the present application to solve the above technical problems is as follows:

[0006] The self-sediment-discharging artificial fish reef comprises a main reef part, an auxiliary reef part and a base part, the main reef part, the auxiliary reef part and the base part are sequentially arranged from top to bottom, the main reef part comprises a plurality of layers of shelter channels, the auxiliary reef part comprises two layers of flow channels, and the two layers of flow channels are perpendicular to each other in direction.

[0007] The flow channel comprises an inlet section, a contraction section and an outlet section, the longitudinal section of the inlet section and the longitudinal section of the outlet section are isosceles trapezoidal, the longitudinal section of the contraction section is rectangular, the inlet section and the outlet section are symmetrical about the contraction section, the inlet section is narrow inside and wide outside, and the outlet section is narrow inside and wide outside.

[0008] A hole is arranged between the main reef part and the auxiliary reef part, the hole penetrates the main reef part from top to bottom and communicates the two layers of flow channels.

[0009] The beneficial effect is that the structure of the application is beneficial to the discharge of the precipitate in the shelter channel. The principle of the application is that when the ocean current flows from the inlet section of the flow channel, through the contraction section, and then flows out from the outlet section, the cross-sectional area of the flow channel changes gradually from small to large through the contraction section, so the water flow speed through the contraction section increases. This increased water flow speed will make the pressure of the contraction section lower than the pressure of the shelter channel, which is beneficial to the generation of a water flow from the shelter channel to the flow channel. This water flow direction is beneficial to the discharge of the precipitate. Furthermore, the increase of the flow rate of the flow channel is also beneficial to the discharge of the precipitate in the flow channel, reducing the risk of the flow channel being blocked by the precipitate and further blocking the shelter channel. The two flow channels are perpendicular to each other, so as long as the application is vertically placed on the seabed, no matter which direction the ocean current comes from the four directions of the fish reef, it can flow through at least one flow channel.

[0010] Further, each shelter channel includes two channel bottom surfaces, which are high on the outside and low on the inside, and the two channel bottom surfaces in the same shelter channel are symmetrically arranged, and the hole passes through the low side of the channel bottom surface.

[0011] The advantage is that the precipitate in the shelter channel can be discharged by gravity.

[0012] Further, the included angle between the two channel bottom surfaces in the same shelter channel is 165° to 175°.

[0013] The advantage is that it is beneficial to the discharge of the precipitate and the number of shelter channels on the main reef part.

[0014] Further, the main reef part is a rectangular solid, the shelter channel penetrates two opposite sides of the main reef part, and the shelter channel is provided with a window on the other two opposite sides of the main reef part, and the window is rectangular.

[0015] The advantage is that it is beneficial for the fish to enter the shelter channel from four directions.

[0016] Further, the hole is provided with a pull rope, the pull rope passes through the hole from the lower flow channel and is pulled out of the main reef part, and the end of the pull rope is connected with a floating ball.

[0017] The advantages are that: since the seawater is flowing and even shakes up and down under the action of waves, the floating ball shakes in the seawater, and since the floating ball is subjected to the buoyancy, the pull rope is always "tensed". The shaking causes the pull rope to make "agitation" in the hole, and the agitation is beneficial to reducing the risk of the hole being blocked by some waterweeds or other types of "floc", and thus is beneficial to guaranteeing the smoothness of the hole.

[0018] Further, the floating ball is provided with a plurality of auxiliary rings, each auxiliary ring is distributed around the floating ball, and an annular channel is arranged between the auxiliary ring and the floating ball.

[0019] The advantages are that: first, the floating ball can provide shelter for small marine animals; second, it is beneficial to increasing the probability of the floating ball being collided or entangled by marine animals, and is beneficial to improving the cleaning effect on the hole.

[0020] Further, the lower layer flow channel is provided with a shaking plate and a plurality of limiting ropes.

[0021] In the lower layer flow channel, one end of the limiting rope is connected to one side of the contraction section, the other end of the limiting rope is connected to the other side of the contraction section, the length of the limiting rope is greater than the width of the contraction section, and the shaking plate is connected to each limiting rope.

[0022] The pull rope is connected to each limiting rope, so that the pull rope can shake the limiting rope.

[0023] The advantages are that: when the floating ball shakes in the seawater, the position of the end of the pull rope also changes (the lifting and lowering are most obvious, and there is also a certain change in the front and back and left and right positions), this change process causes the shaking plate to dynamically shake in the lower layer flow channel, and this shaking is also accompanied by a change in the inclination degree of the shaking plate in the seawater, so that this "shaking" can actually play a role similar to the "blade" of a pump, which is beneficial to the inflow and outflow of seawater in the lower layer flow channel, which can avoid the accumulation of sediments in the lower layer flow channel, and greatly improve the discharge capacity of the invention.

[0024] Further, the shaking plate is provided with a plurality of through holes, and the through holes penetrate the shaking plate along the width of the shaking plate.

[0025] The limiting rope passes through the through hole for connecting the shaking plate.

[0026] The advantages are that: the shaking plate and the limiting rope can slide relative to each other, which improves the amplitude range of the sliding action of the shaking plate in the lower layer flow channel, and improves the "water exchange" capacity of the flow channel in the lower layer.

[0027] Further, the lower end of the pull rope is provided with a horizontal rod, the horizontal rod is located in the lower layer flow channel, a plurality of rope rings are arranged on the horizontal rod, the limiting rope passes through the rope rings to establish a connection between the limiting rope and the pull rope.

[0028] The advantage is that the horizontal rod has a certain lifting capacity for the limiting rope and a certain relative movement capacity relative to the limiting rope, which is beneficial to dynamically adjusting the orientation and inclination angle of the limiting rope.

[0029] Further, the two sides of the horizontal rod are respectively provided with the shaking plates.

[0030] The advantage is that the inclination angle of the part of the limiting rope located on the two sides of the horizontal rod is different, which is beneficial to the left and right shaking effect of the water flow in the lower layer flow channel, and the left and right shaking effect is beneficial to improving the self-cleaning effect of the lower layer flow channel.

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Implementation Method 1

[0043] like Figures 1 to 6 As shown, the self-draining sediment-type artificial reef includes a main reef section 1, a secondary reef section 2, and a base section 3. The main reef section 1, secondary reef section 2, and base section 3 can be fabricated from concrete into a single integrated structure. The weight of the base section 3 should be greater than the sum of the weights of the main reef section 1 and the secondary reef section 2 to minimize the center of gravity of the invention. The main reef section 1, secondary reef section 2, and base section 3 are arranged sequentially from top to bottom. The main reef section 1 includes multiple layers of protective channels 4, and the secondary reef section 2 includes upper and lower flow channels. The upper and lower flow channels are perpendicular to each other. For ease of description, the upper flow channel is referred to as the upper flow channel 21, and the lower flow channel is referred to as the lower flow channel 211.

[0044] like Figure 3 and Figure 4 As shown, the structure of the flow channel is illustrated using the lower flow channel 211 as an example. The lower flow channel 211 includes an inlet section 212, a contraction section 213, and an outlet section 214. Taking the direction of water flow from the inlet section 212 through the flow channel and out of the outlet section 214 as a reference, the section parallel to this flow direction is called the longitudinal section, and the section perpendicular to it is called the cross section. The longitudinal sections of the inlet section 212 and the outlet section 214 are isosceles trapezoids, while the longitudinal section of the contraction section 213 is rectangular. The inlet section 212 and the outlet section 214 are symmetrical about the contraction section 213. The part of the inlet section 212 closest to the contraction section 213 is defined as its "inner" section, and the part of the inlet section 212 away from the contraction section 213 is defined as its "outer" section. The inlet section 212 is narrower inside and wider outside. Similarly, the part of the outlet section 214 closest to the contraction section 213 is defined as its "inner" section, and the part of the outlet section 214 away from the contraction section 213 is defined as its "outer" section. The outlet section 214 is narrower inside and wider outside.

[0045] like Figures 1 to 6As shown, a channel 5 is provided between the main reef section 1 and the secondary reef section 2. The channel 5 runs through the main reef section 1 from top to bottom and connects the upper and lower flow channels.

[0046] like Figures 1 to 6 As shown, this invention needs to be deployed to the seabed when in use, and is particularly suitable for sea areas with ocean currents. The structure of this invention facilitates the removal of sediment from the protective channel 4. The principle behind this invention's advantage in removing sediment from the protective channel 4 is that as the ocean current flows in from the inlet section 212 of the channel, passes through the contraction section 213, and then flows out from the outlet section 214, the cross-sectional area of ​​the channel gradually decreases → flows through the contraction section 213 → then gradually increases again. Therefore, the water velocity flowing through the contraction section increases. This increased water velocity causes the pressure in the contraction section 213 to be lower than the pressure in the protective channel 4. This facilitates the generation of a water flow from the protective channel 4 into the main channel, and this flow direction is conducive to sediment removal. This, in turn, helps to improve the service life of the reef. Simultaneously, the increased flow velocity in the channel also helps to remove sediment from the channel, reducing the risk of sediment accumulation in the channel and subsequent blockage of the protective channel. The upper and lower channels are oriented perpendicularly to each other, so that as long as the invention is placed vertically on the seabed, it can flow through at least one channel regardless of which of the four directions the ocean current comes from.

[0047] like Figure 3 As shown, each shelter channel 4 includes two channel bottom surfaces 41, with the outer side of the two channel bottom surfaces 41 being higher than the inner side. The two channel bottom surfaces 41 located in the same shelter channel 4 are symmetrically arranged. The channel passes through the lower side of the channel bottom surface 41 (the direction of the channel passing through can be seen from the direction of the pull rope 6 in the figure). This structure of the shelter channel 41 facilitates the sliding of sediment falling on the channel bottom surface 41 under its own weight, further facilitating the discharge of sediment. The included angle between the two channel bottom surfaces 41 located in the same shelter channel 4 is 165° to 5°, which not only facilitates the discharge of sediment in the shelter channel 4 from the channel under its own weight, but also helps to ensure the number of shelter channels on the main reef section 1.

[0048] like Figures 1 to 3 As shown, the main reef section 1 is rectangular, and the shelter passage 4 runs through two opposite sides of the main reef section. The shelter passage 4 has windows 42 on the other two opposite sides of the main reef section, and these windows 42 are rectangular. This allows fish to enter the shelter passage from four directions.

[0049] like Figures 1 to 3As shown, the hole 5 is provided with a pull rope 6, the pull rope 6 is pulled out of the main reef part 1 through the hole 5 from the lower layer flow channel, and the end of the pull rope 6 is connected with a floating ball 61; the bottom of the lower layer flow channel 211 is provided with a bottom nose 215 (if the auxiliary reef part 215 is made of concrete, the root of the bottom nose 215 can be pre-buried and arranged during pouring), and the lower end of the pull rope 6 can be buckled to the bottom nose 215. Because seawater is flowing, even under the action of waves, it will sway up and down, so the floating ball will sway in seawater, and this swaying will cause the pull rope 6 to perform an "agitation" action in the hole 5, which is beneficial to reducing the risk of the hole 5 being blocked by some waterweeds or other types of "floc", and thus is beneficial to ensuring the smoothness of the hole. The agitation cooperates with the water flow direction of the hole 5 to the flow channel, and has a good anti-blocking effect.

[0050] As shown in Figures 1 to 3 As shown, the floating ball 61 is provided with a plurality of auxiliary rings 62, the auxiliary rings 62 are distributed around the floating ball 61, and the auxiliary rings 62 and the floating ball 61 are provided with ring channels. The auxiliary rings 62 can provide a certain shelter for smaller marine animals, and can also increase the contact probability of marine organisms (such as fish or kelp) passing through and / or flowing through this place. When these marine organisms collide with or entangle (kelp) the auxiliary rings 62, the swaying amplitude of the floating ball 61 will be increased. This is beneficial to further improving the self-cleaning ability of the hole 5.

[0051] Embodiment two

[0052] Compared with the first embodiment, the second embodiment further improves the lower layer flow channel.

[0053] As shown in Figure 7 and Figure 8 As shown, the lower layer flow channel is provided with a swaying plate 7 and a plurality of limiting ropes 216. The density of the swaying plate 7 is slightly greater than the density of seawater, so that the swaying plate 7 located in seawater has a sinking tendency under the action of gravity. In the lower layer flow channel, one end of the limiting rope 216 is connected to one side of the contraction section, and the other end of the limiting rope 216 is connected to the other side of the contraction section - a rope nose can be provided on the vertical surface on both sides of the contraction section, and then used to connect the limiting rope, and the rope nose can be connected to the auxiliary reef part by pre-buried or expansion screw. The length of the limiting rope 216 is greater than the width of the contraction section 213, so that the limiting rope 216 has a certain inclination (inclination in each dimension) in the lower layer flow channel 216, and thus the swaying plate 8 has a certain degree of freedom of swaying. The swaying plate 7 is connected with the limiting ropes 216. The pull rope 6 is connected with the limiting ropes 216, so that the pull rope 6 can sway with the limiting ropes 216.

[0054] As shown in Figures 7 to 8As shown, when the float ball 61 is swaying in the seawater, the position of the end of the pull rope 6 also changes (the lifting is most obvious, and it is also accompanied by a certain front and back and left and right position change), this change process makes the swaying plate dynamically sway in the lower flow channel 211, and this swaying is also accompanied by a change in the inclination degree of the swaying plate 7 in the seawater, so that this "swaying" can actually play a role similar to the "blade" of a pump, which is beneficial to the entry and discharge of seawater into and out of the lower flow channel 211, which can avoid the accumulation of sediments in the lower flow channel 211, and greatly improve the discharge capacity of the present application.

[0055] As shown in Figures 7 to 9 , the swaying plate 7 is provided with a plurality of through holes 71 which penetrate the swaying plate 7 along the width of the swaying plate 7. The limiting rope 216 passes through the through hole 71 for connecting the swaying plate 7. The lower end of the pull rope 6 is provided with a crossbar 8 which is located in the lower flow channel, and the crossbar 8 is provided with a plurality of rope rings 81, and the limiting rope 216 passes through the rope ring 81 to establish a connection between the pull rope 6. In this way, the crossbar 8 not only has a certain lifting capacity for the limiting rope 216, but also has a certain relative movement capacity with respect to the limiting rope 216. This relative movement capacity is beneficial to dynamically adjusting the orientation and inclination angle of the limiting rope 216, and the change in the orientation and inclination angle of the limiting rope 216 will cause the posture of the limiting plate to change, thereby improving the water exchange capacity of the lower flow channel.

[0056] It should be noted that the connection between the pull rope and each limiting rope can be direct connection in addition to the indirect connection through the crossbar intermediate connecting piece in the present embodiment, for example, the end of the pull rope is tied with a plurality of knots, and one knot connects one limiting rope.

[0057] As shown in Figure 7 and Figure 8 , the two sides of the crossbar 8 are each arranged with a swaying plate 7. The inclination angles of the portions of the limiting rope located on the two sides of the crossbar are different, and this difference is beneficial to the left and right swaying effect of the water flow in the lower flow channel, which is beneficial to improving the self-cleaning effect of the lower flow channel.

[0058] As shown in Figures 7 to 9 , the swaying plate 7 actually enhances the flow capacity of the water flow in the lower flow channel 211, and the water flow in the lower flow channel 211, especially when it is discharging, is beneficial to "inhaling" and supplementing water from the upper flow channel and the shelter channel. This process enhances the overall sediment discharge capacity of the present application.
