Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, and more specifically refers to an overflow box used in an aquaculture pond. Background Art

[0002] Aquaculture ponds are mainly used to raise fish fry. In order to facilitate water changes and save water resources, most aquaculture ponds currently use recirculating water aquaculture. To meet the needs of recirculating water aquaculture, a bottom outlet is usually set at the bottom center of the aquaculture pond for drainage and sewage discharge.

[0003] After a period of aquaculture, some floating foam will be generated on the surface of the aquaculture water, which cannot be discharged from the bottom outlet. Therefore, in order to remove the floating foam, an overflow port is opened on the upper side wall of the aquaculture pond, and an anti-escape net is fixedly installed at the overflow port. An overflow box is installed on the outside of the overflow port, and the bottom of the overflow box is connected to the microfiltration system through an outlet pipe. The microfiltration system filters and treats the aquaculture wastewater and then returns it to the aquaculture pond. The existing overflow box mainly includes a box body with an open top surface, one of the sides of the box body forms a notch, and a baffle is fixedly installed on the inner side of the notch at the notch, and the height of the baffle cannot be adjusted. However, since the water level of the aquaculture water in the aquaculture pond is not fixed, it will drop during normal circulation due to the microfiltration system filtering and discharging part of the sewage, and rise during water replenishment. Therefore, the fixed height baffle cannot filter the floating foam when the water level is too low, and when the water level is too high, more aquaculture water will flow into the overflow box from the top surface and be discharged, affecting the drainage flow of the bottom outlet, resulting in the inability to discharge the dirt at the bottom of the pool. To this end, we provide an overflow box for aquaculture ponds. Utility Model Content

[0004] The utility model provides an overflow box for an aquaculture pond, so as to solve the problems that the height of a baffle at a notch groove of an existing overflow box cannot be adjusted, the floating foam cannot be removed when the water level in the aquaculture pond is too low, and the flow rate of the bottom outlet is affected when the water level is too high, resulting in the inability to discharge dirt.

[0010] In a preferred embodiment, the bottom of the overflow box is connected to a drain pipe and a water outlet pipe, the drain pipe is connected to the bottom outlet of the aquaculture pond, and the water outlet pipe is connected to the microfiltration system.

[0011] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0012] In addition to being provided with a lower baffle fixed to the bottom at the notch groove of the box body of the utility model, a guide groove and an upper baffle are additionally provided on the side of the lower baffle, and a floating ball is provided between the upper baffle and the overflow port, so that the floating ball is connected to the lower baffle, and the buoyancy of the floating ball is utilized to drive the upper baffle to move up and down, so as to meet the needs of removing floating foam under different water levels, so that the water flow rate of the aquaculture water from the overflow port is maintained at a lower ratio, and the flow rate of the bottom discharge port is prevented from being too small to discharge the dirt at the bottom of the pool body.

[0017] The specific implementation of the present invention is described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details. For well-known components, methods and processes, they are not described in detail below.

[0018] An overflow box for an aquaculture pond, referring to Figure 1 , installed at the overflow port 100 on the upper part of the aquaculture pond 1. A bottom outlet 101 is provided at the bottom center of the aquaculture pond 1, through which the aquaculture water and the dirt at the bottom of the pond are discharged to the microfiltration system for filtration treatment, and then returned to the aquaculture pond through the return pipe.

[0019] Reference Figures 2 to 4 The overflow box includes a box body 20 with an open top surface, and the box body preferably adopts a rectangular parallelepiped structure. A notch groove 200 corresponding to the overflow port 100 is formed on one side of the box body 20. A lower baffle plate 21 is fixedly provided in the box body inside the notch groove 200, and an upper baffle plate 22 is provided on the side of the lower baffle plate 21. A guide groove 23 is respectively provided on the inner side wall of the box body 20 corresponding to both sides of the upper baffle plate 22, and the two ends of the upper baffle plate 22 are correspondingly installed between the two guide grooves 23.

[0020] Reference Figures 2 to 4 A floating ball 24 is also provided between the upper baffle plate 22 and the overflow port 100. The floating ball 24 is connected to the upper baffle plate 22 through a connecting rod 25, and the floating ball 24 drives the upper baffle plate 22 to move up and down under the buoyancy of the aquaculture water body. The buoyancy of the floating ball 24 is large enough to pull the upper baffle plate 22 to suspend in the aquaculture water body without sinking, and to keep the top surface of the upper baffle plate 22 1-3 cm lower than the water surface of the aquaculture water body, so as to ensure that a small amount of aquaculture water passes through the top surface of the upper baffle plate 22, and the floating foam can pass through the top surface of the upper baffle plate 22 along with the aquaculture water body.

[0021] Reference Figures 2 to 4 The above-mentioned floating balls 24 are preferably two, and the top surfaces on both sides of the upper baffle 22 are symmetrically connected to a connecting rod 25, and the connecting rod 25 is preferably n-shaped, and each connecting rod 25 is correspondingly connected to a floating ball 24.

[0022] Reference Figures 2 to 4 Each of the guide grooves 23 is formed by two convex strips 231 fixed in parallel on the inner wall of the box body 20, wherein the bottom of one convex strip 231 is fixed on the top surface of the lower baffle 24, and the other convex strip 231 extends upward from the bottom surface to the top surface of the box body 20. The guide grooves of this structure can make the upper baffle 22 and the side surface of the lower baffle 21 close to each other, reducing the water flow passing through the gap between them.

[0023] Reference Figure 2 The bottom of the overflow box is connected to a drain pipe 26 and a water outlet pipe 27, wherein the drain pipe 26 is connected to the bottom outlet 100 of the aquaculture pond 1, and the water outlet pipe 27 is connected to the microfiltration system.

[0024] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
