Description

Technical Field

[0001] This utility model relates to the technical field of ecological restoration and water area operation and maintenance engineering, and in particular to a fish guide channel structure for deep and shallow water zones. Background Technology

[0002] Existing fishway technologies are mostly designed for large open water bodies such as rivers and reservoirs, employing complex structures such as tiered structures and fish lifts. They rely on power equipment and professional operation and maintenance, and cannot meet the needs of small-scale enclosed water areas in urban parks.

[0003] Currently, urban park lakes and ponds face the problem of excessive fish reproduction, which consumes submerged plants and deteriorates water quality. However, existing solutions have significant drawbacks: manual harvesting is inefficient and labor-intensive, making it difficult to cope with population rebounds caused by tourists releasing fish indiscriminately; the use of fish control agents can easily disrupt the ecological balance; and some simple fish-guiding structures lack dredging design, leading to sediment accumulation that can clog channels and affect the effectiveness of fish guidance. Therefore, the core problem with existing technologies lies in the lack of a fish-guiding structure that is suitable for small-scale park waters, requires no complex equipment, is easy to operate and maintain, and can simultaneously control fish, protect vegetation, and prevent siltation.

A bottom mud trough is provided at the bottom of the fish guide channel module 1 to collect sludge and other contaminants for subsequent cleaning.

[0032] Compared with the prior art, the fish guide channel structure with shallow and deep water zones provided in this utility model embodiment can effectively guide fish through the fish guide channel module 1, effectively avoid the degradation of submerged plants caused by excessive fish, and concentrate the silt in the water into the bottom mud tank for subsequent regular cleaning.

[0033] It should be noted that the width of the fish guide channel module 1 is not less than 1m.

[0034] In an optional implementation of this embodiment, refer to Figure 1 and Figure 2 The fish guide channel module 1 includes a concrete bottom mud trough wall 11 and a filter screen structure 12. The concrete bottom mud trough wall 11 is distributed along the water flow direction and has a bottom mud trough inside. Multiple filter screen structures 12 are provided, and multiple filter screen structures 12 are detachably connected to the top of the concrete bottom mud trough wall 11 in sequence along the extension direction of the concrete bottom mud trough wall 11 to concentrate the silt in the bottom mud trough.

[0035] Specifically: A U-shaped mud trough is provided inside the concrete mud trough wall 11, and the concrete mud trough wall 11 is distributed along the direction of water flow so that water can flow towards the sluice gate module 5 connected to the end of the concrete mud trough wall 11. A filter screen structure 12 is provided on the top of the concrete mud trough wall 11. Multiple filter screen structures 12 are provided and distributed in sequence, so that a filter screen structure 12 is added above the mud trough. The filter screen structure 12 is used to intercept silt and impurities such as residual bait.

[0036] Furthermore, referring to Figure 1 and Figure 2 The filter structure 12 includes a stainless steel filter 121 and multiple connecting components 122. The stainless steel filter 121 is detachably connected to the top of the concrete bottom mud trough wall 11 through the multiple connecting components 122. Multiple stainless steel filter 121s are provided and are distributed sequentially along the extension direction of the concrete bottom mud trough wall 11.

[0037] Specifically, the stainless steel filter screen 121 is detachably connected to the top of the concrete bottom mud tank wall 11 through multiple corresponding connecting components 122, so that a filter structure can be added to the bottom mud tank, thereby effectively intercepting silt and residual bait and other impurities; when cleaning is required, the stainless steel filter screen 121 can be opened to facilitate the cleaning of the silt in the bottom mud tank.

[0038] Furthermore, referring to Figure 1 and Figure 2 The connecting component 122 includes a buckle 1221 and a sealing strip 1222. The stainless steel filter screen 121 is detachably connected to the concrete bottom mud trough wall 11 through the corresponding buckle 1221. The sealing strip 1222 is provided at the joint between the stainless steel filter screen 121 and the concrete bottom mud trough wall 11.

[0039] Specifically: the fish-guiding channel module 1 forms a tiered filtration-gravity mud-guiding integrated structure, with its overall width matching the width of the fish-guiding channel module 1 to ensure no side leakage of water flow; the stainless steel filter screen 121 is fixed to the top of the concrete bottom mud tank wall 11 by stainless steel clips 1221, and is sealed at the edges with rubber sealing strips 1222 to prevent silt and other impurities from entering through the joints without passing through the stainless steel filter screen 121. The tiered filtration-gravity mud-guiding integrated structure is divided into two layers from top to bottom: the upper layer intercepts silt, uneaten food, and other impurities while allowing fish to pass through; the lower layer is a concrete bottom mud tank that relies on gravity to promote the automatic collection and centralized removal of silt.

[0040] Furthermore, referring to Figure 1 and Figure 2 The width of the bottom mud trough is half the width of the fish guide channel module 1, and the depth of the bottom mud trough is not less than 0.5m. The bottom of the bottom mud trough slopes downward toward the sluice gate module 5. The aperture of the stainless steel filter screen 121 is not greater than 0.5cm.

[0041] Specifically: the depth of the bottom mud trough is not less than 0.5m, the bottom of the bottom mud trough slopes downward toward the sluice gate module 5 so that water can flow toward the sluice gate module 5, and a rectangular slot is reserved at the end of the concrete bottom mud trough wall 11.

[0042] In an optional implementation of this embodiment, refer to Figure 1 and Figure 2 The tiered guide wall module 2 includes a concrete component 21, an ecological gabion 22, and an ecological blanket 23. The concrete component 21 is connected sequentially along the connection between the shallow water module 3 and the deep water module 4. The concrete component 21 is fitted with an ecological gabion 22, and the ecological blanket 23 is provided on the outside of the ecological gabion 22.

[0043] Specifically: Concrete component 21 is vertically positioned between shallow water module 3 and deep water module 4. An ecological gabion 22 is installed outside the concrete component 21, containing stones of appropriate size. An ecological mat 23, which can be a coconut fiber ecological mat, is installed outside the ecological gabion 22. It should be noted that the tiered guide wall module 2 is arranged in a ring around the shallow water module 3, decreasing in a tiered manner from the shallow water module 3 to the deep water module 4.

[0044] In an optional implementation of this embodiment, refer to Figure 1 and Figure 2 Submerged plants are planted in the shallow water module 3, and the water depth of the shallow water module 3 is set to 0.5-1m.

[0045] Specifically: Shallow water module 3 is a shallow water area suitable for the growth of submerged plants, and its water depth is set to 0.5-1m.

[0046] In an optional implementation of this embodiment, refer to Figure 1 and Figure 2 The bottom of the deep water module 4 is set as a flat original mud base, and the water depth of the deep water module 4 is not less than 2m.

[0047] Specifically: Module 4 of the deep water area is a deep water area for fish to inhabit, with a water depth of not less than 2.0m, and the original muddy base is preserved at the bottom.

[0048] In an optional implementation of this embodiment, refer to Figure 1 and Figure 2 The fish guide channel structure in the deep and shallow water zones also includes multiple ecological buoy modules 6, which are located within the deep water zone module 4.

[0049] Specifically: The ecological buoy module 6 is placed on the side of the deep water module 4 away from the shallow water module 3. The ecological buoy module 6 is used to allow fish to lay their eggs on it and to provide temporary habitat for fish so as to facilitate fish reproduction.

[0050] In an optional implementation of this embodiment, refer to Figure 1 and Figure 2 The ecological buoy module 6 includes a spherical shell 61, reed fluff 62, and an anchor stainless steel hanging ring 63. The spherical shell 61 is filled with reed fluff 62, and the spherical shell 61 is connected to the bottom of the deep water module 4 through the anchor stainless steel hanging ring 63.

[0051] Specifically: Module 4 in the deep water area is equipped with precast concrete anchor blocks, and its top is equipped with stainless steel hanging rings. The density of the stainless steel hanging rings is one every 5-10m, which are used to fix the spherical shell 61. The spherical shell 61 includes a bamboo spherical frame and an outer coconut fiber outer layer, while reed fluff 62 is used as filler to fill the spherical shell 61. The spherical shell 61 is connected to the anchor block stainless steel hanging ring 63, and the anchor block stainless steel hanging ring 63 can be connected to the stainless steel hanging ring through natural hemp rope.

[0052] It should be noted that the bamboo spherical frame is woven from natural bamboo strips, with a spherical side length of 100mm. Its outer layer is wrapped with 2cm thick coconut fiber, and the interior is filled with dried and compressed reed fluff 62. The stainless steel hanging ring 63 of the anchor block is connected to the center of the top of the bamboo spherical frame. One end of a natural hemp rope is tied to the stainless steel hanging ring 63, and the other end is fixed to the stainless steel hanging ring of the precast concrete anchor block. The length of the natural hemp rope matches the water depth in the deep water area, ensuring that the ecological buoy module 6 is suspended at a depth of 1.0-1.5m underwater.

[0053] The main body of the sluice gate module 5 is a manual screw-type sluice gate with solar assistance, consisting of a 304 stainless steel gate plate, a screw hoist, water level markings, and a concrete gate seat. The width of the sluice gate is the same as that of the fish guide channel module 1, which is about 1.0-1.5m. The gate plate is adapted to the water depth of the deep water module 4. The concrete gate seat is cast at the bottom and both sides of the entrance end of the fish guide channel module 1 and is integrally formed with the side wall of the channel. In normal operation, the gate is fully open, and the water levels in the fish guide channel module 1 and the deep water module 4 are consistent, both not less than 2.0m, allowing fish to pass freely. When there is an overabundance of fish, the gate height is lowered via a screw-operated hoist, causing the water level in the fish guide channel module 1 to be 0.3-0.5m lower than that in the deep water module 4, creating a water level difference. This guides the fish in the deep water module 4 downstream into the fish guide channel module 1 and out. Water level markings are engraved on the side wall of the gate seat with an accuracy of ±0.05m, facilitating precise control of water level adjustments by maintenance personnel and preventing excessive water level reduction from impacting the aquatic ecosystem. Through these methods, fish are further guided out through the fish guide channel outlet, achieving convenient fish control and significantly reducing park operation and maintenance costs.
