Abstract
Description
Technical Field
[0001] This utility model relates to the field of aquaculture technology, and in particular to a water inlet component and a fish pond having the same. Background Technology
[0002] In the design of aquaculture ponds, self-cleaning capability is a key characteristic, requiring the water to rotate at a uniform speed within the pond. The water rotation speed in the pond should be as uniform as possible from the pond walls to the center and from the surface to the bottom, and fast enough to generate self-cleaning ability. This allows more oxygen to be carried into the pond and waste to be quickly flushed away; the speed at which sediment particles are flushed to the center of the pond is 15-30 cm / s.
[0003] However, in addition to meeting self-purification requirements, the physiological needs of farmed fish must also be met; the water flow velocity should not exceed the suitable intensity for the fish. Generally, a velocity of 0.5–2.0 times the fish's body length (BL / sec) is ideal, maintaining the fish's health, muscle tone, and respiration. The rotation rate can be controlled through the inlet design; therefore, the jet pattern and direction at the inlet and outlet become the main determinants of water quality uniformity and the health of the farmed fish.
[0004] In the current design of aquaculture ponds, the water inlet pipe has holes at intervals at the top and bottom. Water enters from one end of the water inlet pipe and is then supplied outward from each hole. Due to the difference in distance between each hole and the water inlet end, there is a difference in the outflow velocity of the water from the top and bottom holes.
[0005] Therefore, there is a need for an inlet component and a fishpond that can provide uniform water supply, achieve the same flow rate and stable water output, and meet the growth environment requirements of fish fry. Utility Model Content
[0006] In order to overcome the shortcomings of the prior art, this utility model provides a water inlet component and a fish pond having the same.

[0013] As a further improvement of this utility model, the circumferential area between the two edges of the first array is C, and the lateral area of the water inlet inner pipe is D, where C≤0.25D.
[0014] As a further improvement of this utility model, the angle between the direction of the first array and the direction of the second array is 180°.
[0015] A fish pond includes a pond body, a water inlet assembly as described above, and a drainage assembly, wherein the water inlet pipe of the water inlet assembly extends into the pond body.
[0016] As a further improvement of this utility model, the water inlet assembly is provided with multiple water inlet pipes, which are evenly arranged on the edge of the pool body. The direction of the line connecting the water inlet pipe and the center of the pool body is the first direction, and the direction of the second water inlet hole of the water inlet pipe is the second direction. The first direction and the second direction are not parallel.
[0017] As a further improvement of this utility model, the water inlet assembly is provided with two parts, and the second water inlet holes of the two water inlet pipes are oriented in opposite directions, with the first direction being perpendicular to the second direction.
[0018] According to the above-described solution, the beneficial effects of this utility model are as follows:
[0019] This utility model adopts a nested inner and outer pipe water inlet structure. Water flows through the inner water inlet pipe into the outer water inlet pipe, and then into the pool body through the outer water inlet pipe.

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0031] See Figure 1 -6. This utility model provides a water inlet assembly for supplying water to a pool body 2. The water inlet assembly 3 includes a water inlet fixing bracket 31 disposed on the outer wall of the pool body 2 and a water inlet connecting pipe 32 disposed on the water inlet fixing bracket 31. The first end of the water inlet connecting pipe 32 is connected to an external water tank 33, and the second end of the water inlet connecting pipe 32 is connected to a water inlet pipe. The water inlet pipe extends into the pool body 2. Preferably, the water inlet fixing bracket 31 is fixedly connected to the side wall of the pool body 2 by a stainless steel clamp. The angle between the water inlet fixing bracket 31 and the side wall of the pool body 2 is adjustable. The water inlet pipe includes a top connecting to the water inlet. The water inlet inner pipe 34 is connected to pipe 32, and the water inlet outer pipe 35 is sleeved outside the water inlet inner pipe 34. There is a gap between the water inlet outer pipe 35 and the water inlet inner pipe 34. Preferably, the water inlet inner pipe 34 is made of 304 stainless steel, and the water inlet outer pipe 35 is a thickened engineering plastic product. The bottom of the water inlet outer pipe 35 is sealed, and the top of the water inlet outer pipe 35 is sealed with the water inlet inner pipe 34. Preferably, the bottom of the water inlet outer pipe 35 is completely sealed by argon arc welding, and the top of the water inlet outer pipe 35 is sealed with a silicone sealing ring to achieve a diameter between the water inlet outer pipe 35 and the end face or side wall of the water inlet inner pipe 34. To prevent water leakage from both ends of the outer inlet pipe 35 and improve stability, the inner inlet pipe 34 is provided with several first inlet holes 36, and the outer inlet pipe 35 is provided with several second inlet holes 37. Water flows from the external water tank 33 through the inlet connecting pipe 32 and the inner inlet pipe 34, and enters the outer inlet pipe 35 through the first inlet holes 36. A stable laminar flow is formed in the outer inlet pipe 35, eliminating turbulence, and finally the water is injected into the pool body 2 through the second inlet holes 37, completing the water supply to the pool body 2. This utility model adopts a nested inner and outer pipe design. The water inlet structure, through the cooperation of the inner water inlet pipe 34 and the outer water inlet pipe 35, can maintain a constant water pressure when water level fluctuations occur. In addition, the bottom sealing structure of the outer water inlet pipe 35 forms a secondary water distribution cavity, ensuring that the water flow entering the pool 2 is distributed in a fan shape. This ensures that the water flow rate of each second water inlet hole 37 on the outer water inlet pipe 35 is the same and the water output is stable, achieving uniform water supply. Compared with the traditional direct-flow water inlet device, this water inlet structure improves the uniformity of dissolved oxygen distribution by 40%, which meets the growth environment of fish fry.
[0032] As an embodiment of this utility model, the bottom of the inner water inlet pipe 34 is sealed to prevent the bottom of the inner water inlet pipe 34 from communicating with the outer water inlet pipe 35, and to ensure that the water flow enters the outer water inlet pipe 35 from the side wall of the inner water inlet pipe 34. This forms a stable water flow in the outer water inlet pipe 35, thereby eliminating turbulence. It also prevents the water pressure at the bottom of the outer water inlet pipe 35 from being too high, which would cause the water inlet speed in the second water inlet hole 37 near the bottom to be too fast. This ensures that the water inlet speed of each second water inlet hole 37 is the same, and achieves uniform water supply.
[0033] As one embodiment of this utility model, the radius of the first inlet hole 36 is smaller than the radius of the second inlet hole 37. According to the principle of fluid mechanics, when water flows from the inner inlet pipe 34 into the outer inlet pipe 35, a higher velocity gradient will be formed under the same flow conditions due to the smaller cross-sectional area of the first inlet hole 36. When water flows from the outer inlet pipe 35 into the pool body 2, the enlarged cross-section of the second inlet hole 37 effectively reduces the velocity, thereby making the velocity of water flowing from the inner inlet pipe 34 into the outer inlet pipe 35 greater than the velocity of water flowing from the outer inlet pipe 35 into the pool body 2. This differentiated aperture configuration creates a certain difference in the water flow velocity between the inner inlet pipe 34 and the outer inlet pipe 35, which not only ensures the conveying efficiency of the inner inlet pipe 34, but also achieves stable water distribution through the buffer of the outer inlet pipe 35, avoiding turbulent disturbances inside the pool body 2, and improving the overall stability and reliability of water intake.
[0034] As one embodiment of this utility model, the first water inlet hole 36 is arranged in a first array along the axial direction of the inner water inlet pipe 34, and the second water inlet hole 37 is arranged in a second array along the axial direction of the outer water inlet pipe 35. The first water inlet hole 36 and the second water inlet hole 37 are staggered. After the water flows from the first water inlet hole 36 into the outer water inlet pipe 35, it is guided by the outer water inlet pipe 35 and finally enters the pool body 2 from the second water inlet hole 37. The first water inlet hole 36 and the second water inlet hole 37 are both arranged in an array, so that each first water inlet hole 36 and each second water inlet hole 37 are evenly distributed. This can effectively improve the water inlet uniformity of the outer water inlet pipe 35 and enhance the turbulence intensity of the internal flow field of the outer water inlet pipe 35. At the same time, the three-dimensional distribution of the water inlet path is realized through the layered flow guiding design of the inner and outer pipe bodies.
[0035] In one embodiment of this utility model, the circumferential area between the two edges of the second array is A, and the lateral area of the water inlet pipe 35 is B, where A ≤ 0.25B. Taking the water inlet pipe 35 as a circular pipe as an example, the angle corresponding to the distribution range of the second array is within 90°. Taking the axial direction along the water inlet pipe 35 as the column and the circumferential direction of the water inlet pipe 35 as the row, when the second array has only one column, the circumferential area bounded by the left and right ends of the second water inlet hole 37 is A, that is, the angle between the line connecting the left and right ends of the second water inlet hole 37 and the center of the water inlet pipe 35 is within 90°. When the second array has two columns, the circumferential area bounded by the leftmost end of the second water inlet hole 37 on the left and the rightmost end of the second water inlet hole 37 on the right is A. Let A be the angle between the leftmost end of the second water inlet 37 on the left and the rightmost end of the second water inlet 37 on the right, and the center of the outer water inlet pipe 35. Similarly, when the second array has more than two columns, the circumferential area bounded by the leftmost end of the second water inlet 37 on the left and the rightmost end of the second water inlet 37 on the right is A. That is, the angle between the leftmost end of the second water inlet 37 on the left and the rightmost end of the second water inlet 37 on the right, and the center of the outer water inlet pipe 35 is within 90°. This can avoid the water inlet angle of the outer water inlet pipe 35 being too large and the water inlet direction being too dispersed, thereby providing a stable water flow direction to the pool body 2 and improving the overall stability and reliability.
[0036] In one embodiment of this utility model, the circumferential area between the two edges of the first array is C, and the lateral area of the water inlet pipe 34 is D, where C ≤ 0.25D. Taking the water inlet pipe 34 as a circular pipe as an example, the angle corresponding to the distribution range of the first array is within 90°. Taking the axial direction along the water inlet pipe 34 as the column and the circumferential direction of the water inlet pipe 34 as the row, when the first array has only one column, the circumferential area bounded by the left and right ends of the first water inlet hole 36 is C, that is, the angle between the line connecting the left and right ends of the first water inlet hole 36 and the center of the water inlet pipe 34 is within 90°. When the first array has two columns, the circumferential area bounded by the leftmost end of the first water inlet hole 36 on the left and the rightmost end of the first water inlet hole 36 on the right is C, that is, the angle between the line connecting .... The angle between the line connecting the leftmost end of the first water inlet 36 on the right and the center of the inner water inlet pipe 34 is within 90°. Similarly, when the first array has more than two columns, the circumferential area bounded by the leftmost end of the first water inlet 36 on the left and the rightmost end of the first water inlet 36 on the right is C. That is, the angle between the line connecting the leftmost end of the first water inlet 36 on the left and the rightmost end of the first water inlet 36 on the right and the center of the inner water inlet pipe 34 is within 90°. This can avoid the water inlet angle of the inner water inlet pipe 34 being too large and the water inlet direction being too dispersed, thereby forming a stable water flow in the outer water supply pipe 35 and avoiding the phenomenon of water flow collision and conflict in the outer water supply pipe 35 due to excessively dispersed water inlet, thus improving the overall stability and reliability.
[0037] As one embodiment of this utility model, the angle between the direction of the first array and the direction of the second array is 180°, that is, the first array faces away from the second array. The water flow in the inner water inlet pipe 34 is shot from the first water inlet hole 36 to the inner wall of the outer water inlet pipe 35 facing away from the second array. The water flow then flows along the inner wall of the outer water inlet pipe 35 from both sides to the second array, and finally enters the pool body 2 from the second water inlet hole 37. The distance and water pressure of the water flow along both sides of the outer water inlet pipe 35 are equal, so that the water flow on both sides of the second array is uniform, further improving the overall stability and uniformity of water intake.
[0038] See Figure 7 This utility model provides a fish pond, including a pond body 2, a water inlet component 3, and a drainage component. The water inlet pipe of the water inlet component 3 extends into the pond body 2. The water inlet component 3 and the drainage component provide water inlet and drainage functions to the pond body 2 respectively, while enabling the water flow in the pond body 2 to circulate. This prevents oil, impurities, etc. from accumulating in the pond body 2 for a long time, ensuring that the water in the pond body 2 is clean and tidy, and providing a good breeding environment for fish fry.
[0039] As one embodiment of this utility model, the water inlet assembly 3 is provided with multiple water inlet pipes, which are evenly arranged on the edge of the pool body 2. The direction of the line connecting the water inlet pipe and the center of the pool body 2 is the first direction, and the direction of the second water inlet hole 37 of the water inlet pipe is the second direction. The first direction and the second direction are not parallel, that is, the second water inlet hole 37 does not face the center of the pool body 2, nor does it face the side wall of the pool body 2. At the same time, the second water inlet hole 37 of each water inlet pipe is in the same direction, such as counterclockwise or clockwise. Through the cooperation of multiple water inlet pipes, a clockwise or counterclockwise flow direction is provided for the water flow in the pool body 2, so that a stable and uniform water flow is formed in the pool body 2, which is suitable for fish fry breeding and provides a good breeding environment for fish fry.
[0040] As one embodiment of this utility model, the water inlet assembly 3 is provided in two parts, namely, two water inlet pipes are arranged opposite to each other with the center of the pool body 2, and the second water inlet holes 37 of the two water inlet pipes are in opposite directions, with the first direction and the second direction being perpendicular to each other. This can avoid the situation where the angle between the first direction and the second direction is too small, causing the circulating water flow to exist only in the central area of the pool body 2, while the circulation in the edge area of the pool body 2 is not obvious, resulting in the fish fry's breeding environment being limited to the central area of the pool body 2, causing a waste of resources. It can also avoid the situation where the angle between the first direction and the second direction is too large, causing the water flow to impact the inner wall of the pool body 2, resulting in water flow collision and splashing, thereby causing unnecessary impact on the breeding of fish fry.
[0041] In summary, this utility model provides a water inlet component and a fish pond incorporating it. It employs a nested inner and outer pipe water inlet structure. Through the cooperation of the inner water inlet pipe 34 and the outer water inlet pipe 35, the buffering effect of the outer water inlet pipe 35 can maintain a constant water pressure when water level fluctuations occur. Furthermore, the bottom sealing structure of the outer water inlet pipe 35 forms a secondary water distribution chamber, ensuring that the water entering the pond 2 is distributed in a fan-shaped pattern. This ensures that the water flow velocity at each second water inlet hole 37 on the outer water inlet pipe 35 is the same and the water output is stable, achieving uniform water supply. Compared with traditional direct-flow water inlet devices, this water inlet structure improves the uniformity of dissolved oxygen distribution by 40%, meeting the requirements of [the above description is missing from the original text]. Fish fry growth environment; the radius of the first water inlet 36 is smaller than the radius of the second water inlet 37, creating a certain difference in water flow velocity between the inner water inlet pipe 34 and the outer water inlet pipe 35. This ensures the conveying efficiency of the inner water inlet pipe 34 and achieves stable water distribution through the buffer of the outer water inlet pipe 35, avoiding turbulent disturbances inside the pool body 2 and improving the overall stability and reliability of water intake; the angle between the direction of the first array and the direction of the second array is 180°, making the distance and water pressure of the water flow along both sides of the outer water inlet pipe 35 equal, and making the water flow on both sides of the second array uniform, further improving the overall stability and uniformity of water intake.
[0042] It should be emphasized that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
