Description

Technical Field

[0001] The utility model relates to the field of aquaculture, and in particular to a drainage well for an aquaculture pond. Background Art

[0002] The drain outlet is an essential unit for every aquaculture pond. Generally, a drainage well should have two functions: drainage and water level control. Currently, most drainage wells have the above two functions, but workers need to wear specific swimming clothes such as waders to operate, which is very inconvenient. Many aquaculture workers often do not do it because of the inconvenience of operation, resulting in the escape of aquatic products and other losses. In addition, it does not meet the requirements of high-standard aquaculture ponds. Utility Model Content

[0011] (II) Beneficial effects

[0012] Compared with the prior art, the utility model provides a drainage well for an aquaculture pond, which has the following beneficial effects:

[0013] The utility model makes improvements on the prior art. In actual use, the manhole has steps leading to the bottom, which is convenient for controlling the insertion and extraction of pipes and for cleaning silt and other impurities in the manhole. Under normal circumstances, there is no water or only a small amount of water in the well, and the pond can be omitted. The water level or drainage can be controlled in the well with no water or a small amount of water, which is easy to operate. The drainage branch pipe is connected to the end of the pond section and has a movable filter screen, which can be replaced according to the size of the farmed animals to prevent them from escaping, and can also effectively block large particles of impurities in the water from entering the well. The steps down to the pond can provide convenience for cleaning or replacing the blocking net, as well as fishing. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to further illustrate the technical solution of the present application, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0020] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-Figure 3 As shown, a drainage well for an aquaculture pond according to an embodiment of the utility model comprises a well body 1, a well step 2 is arranged inside the well body 1, a drainage branch pipe 3 is arranged on one side of the well step 2, the drainage branch pipe 3 runs through the well body 1, drainage main pipes 4 are symmetrically arranged on both sides of the well body 1, a brick-built pond lowering step 5 is connected to the periphery of the well body 1, and a blocking net 6 is arranged inside the brick-built pond lowering step 5.

[0021] like Figure 1-3As shown, the well body 1: is usually a brick structure, built at a position more than 0.5m away from the edge of the pond; according to the needs of the breeding pond, the depth is between 1.5m-2.5m (usually the depth from the upper mouth of the pond to the bottom of the pond); the width is 1m-1.5m; and it connects the drainage main pipe 4 and the drainage branch pipe 3.

[0022] Well steps 2: Brick steps, built on the side of the well close to the pond, from the top to the bottom of the well, with a width of 0.3m and a height of 0.15m-0.3m. The number of steps is determined according to the depth of the pond, and then the length of the steps is determined according to the number of steps.

[0023] Drainage main pipe 4: The pipe diameter is 0.3m-0.5m, usually a corrugated pipe or a PE pipe, perpendicular to the short side of the well body 1, and connected to the well body 1.

[0024] Drainage branch pipe 3: The pipe diameter is 0.2m-0.4m, which is a PVC pipe, perpendicular to the long side of the well, one end leads to the manhole, and then connected to a right-angle elbow vertically upward to make a movable plug-in pipe. The plug-in pipe does not need to be glued and can be flexibly pulled or inserted to control the water level or drain water; the other end leads to the pond. The drainage branch pipe 3 uses the siphon principle to automatically control the water level by controlling the height of the movable plug-in pipe.

[0025] Brick-built steps down to the pond 5: Brick-built steps, from the top to the bottom of the pond, with the same length as the well, 0.3m wide and 0.15m-0.3m high. The number of steps is determined according to the depth and slope of the pond; the last step close to the bottom of the pond is made of bricks and has a movable filter; the steps provide convenience for cleaning or replacing the nets, and also for fishing.

[0026] Net 6: It is a movable filter made of stainless steel and embedded in the steps. Its width is the same as the height of the steps and its length is the same as the length of the steps. The filter has the function of preventing aquatic products in the pond from escaping and intercepting impurities such as water plants in the pond. Different mesh sizes can be replaced according to the size of the aquaculture species.

[0027] For example, in an existing perch breeding pond, the depth of the pond is 2.5 meters. From fry to adult fish, the water level needs to be controlled from 1m to 2.2m according to different breeding stages. By using the manhole described in the utility model, the water level can be controlled by controlling the length of the plug-in part of the drainage branch pipe 3. Workers do not need to wear special swimming clothes to go into the water, but can directly go to the non-flooded manhole for operation. The water level control is more convenient and the breeding process is more controllable. The net at the end of the branch pipe effectively prevents the perch from escaping, and at the same time intercepts dead fish, water plants and other debris so that they can be fished out in time. After the breeding season is over, the well ladder 2 can be cleaned up, which is more convenient to operate than the traditional ladder-free or vertical ladder.

[0028] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0029] To sum up: the drainage well described in the utility model fully realizes the operability of drainage and water level control. In addition, it also meets the needs of sludge cleaning in the well and the convenience of sludge cleaning, meets the basic needs of drainage and water level control, and makes drainage more convenient and easy to operate, water level control more convenient and easy to operate, and cleaning sludge in the manhole more convenient.

[0030] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
