Detailed Description

The invention is explained in detail below with reference to the accompanying drawings:

as shown in fig. 1-7: a mechanism for efficiently removing sediments in a culture pond, which comprises a sewage collecting pond 1 and a sewage discharging channel 2,

the bottom surface of the sewage collecting tank 1 is an inclined surface 11 which inclines from the side edge to the gap 3; generally speaking, the sewage draining passage 2 is located at the middle position below the sewage collecting tank 1, so the cross section of the bottom surface of the sewage collecting tank 1 is in a V shape.

and a plugging object 8 for plugging the gap 3 is arranged above the gap 3, and a floating body 81 is arranged on the plugging object 8 and can enable the plugging object 8 to float and sink along with the excess and the deficiency of the liquid in the sewage collecting tank 1. Because the plugging object 8 floats and sinks along with the excess and deficiency of the liquid in the sewage collecting tank 1, when the liquid is less than a certain degree, the plugging object 8 can plug the gap 3, the liquid in the sewage collecting tank 1 can only flow out from the other end of the sewage discharge channel 2 and the opening communicated with the sewage collecting tank 1, and a small amount of water enters the sewage discharge channel 2 through the opening to flush the sewage discharge channel 2. The plugging object can be a pipe body or a square body.

Wherein, an adjusting rope 82 which connects the plugging article 8 and the floating body 81 and adjusts the distance between the plugging article and the floating body is arranged between the plugging article and the floating body. By controlling or adjusting the length of the adjusting rope 82, the time for the plugging object 8 to plug the gap can be controlled.

The left side wall and the right side wall of the sewage discharge channel 2 are provided with limit baffles 83 for limiting the plugging object 8. The plugging tube can be prevented from deviating or inclining.

When the sewage discharge channel 2 is designed, sometimes the other end of the sewage discharge channel 2 is communicated with the sewage collecting pool 1, and the length of the plugging object 8 is not less than that of the gap 3. Thus, after the plugging object 8 plugs the gap, part of water flow can flow into the sewage drainage channel 2 through the other end of the sewage drainage channel 2 to flush the sewage drainage channel 2.

Sometimes the trapway 2 is closed at the other end and the length of the blocking piece 8 is less than the length of the slot 3. Therefore, after the plugging object 8 plugs the gap, a small section of gap is left to still enable water flow to flow into the gap, and generally speaking, the ordinary sewage drainage channel 2 of the gap which is not plugged is located at one end far away from the sewage drainage port 4. Of course, the length of the plugging object 8 is equal to the length of the gap 3, and the small hole is formed on the plugging object 8, so that the plugging effect is dissipated in the area where the small hole is formed on the plugging object 8.

And a switch structure for controlling whether the sewage draining channel 2 is drained or not is arranged at the sewage draining outlet 4 of the sewage draining channel 2. The switch structure here can be a water valve (electric or manual) or directly a cannula.

The caliber of the sewage discharge channel 2 is unchanged from left to right, and the caliber of the sewage discharge channel 2 can also be gradually reduced from left to right.

The opening of a channel 5 at the bottom of the sewage collecting pond 1 (connected with a sewage outlet at the bottom of the culture pond) is close to one side of the sewage outlet 4. Therefore, a large amount of sediments such as excrement can be ensured to be close to the outlet of the sewage discharge channel 2, and the sediments such as the excrement can be conveniently gathered, deposited (concentrated). The channel 5 may be provided with a built-in valve or a plug at the outlet of the channel 5 to achieve a "shut-off" design.

It still includes water lifting equipment, water lifting equipment sets up and gathers dirty pond 1 and keep away from the opposite side of blowdown passageway 2 for will gather in the dirty pond water purification drainage to breeding the pond 7. The water lifting device can be a water pump with a drainage tube or a pneumatic water lifting device.

The width of the slit 3 is preferably 2mm or more for discharging dirt such as feces.

The working principle is as follows:

the utility model discloses a using-way has two kinds:

first one

The sewage collecting tank 1 and the culture tank 7 are communicated with each other through a channel 5 all the year round (of course, interception devices such as valves, insertion pipes and the like are preferably installed); because the bottom of the sewage collecting pool 1 is communicated with the bottom of the culture pool 7, the water level of the sewage collecting pool and the water level of the culture pool are equal due to the principle of the communicating vessel. After a water lifting device is arranged at one end of the sewage collecting pool 1 far away from the sewage discharge outlet 4, an internal circulation is formed between the culture pool 7 and the sewage collecting pool 5, and sediments such as excrement in the culture pool 7 flow into the mechanism; as the water flow becomes slow, the sediments such as excrement and urine in the mechanism sink, and the bottom surface of the sewage collecting pool 1 is an inclined surface 11 inclined from the side edge to the gap 3 in a V shape, and is converged at the gap 3 to fall into the sewage channel 2 (concentration) under the driving of the slow water flow. After the culture pond circulates for a period of time, a large amount of sediments such as excrement and the like are accumulated (more) in the sewage discharge channel 2; the drain 4 is connected with the sewage draining channel 2, and because the sewage draining channel 2 is at the lowest position, when the drain 4 is opened, a large amount of precipitates such as excrement concentrated and gathered in the sewage draining channel 2 can be quickly discharged. Like this, at the "inner loop" interval of breeding process through a period of time, in time "transfer" the deposit such as 7 excrement and urine of breed pond to gather in gathering dirty pond 1, and rethread sewage pipes 2 sinks, concentrates, and drain 4 carries out outside the quick discharge pond, receiving under the restriction of shutoff article 8 to reach and reduce the displacement by a wide margin and do not influence the effect of breeding the animal again.

Second kind

The channel 5 is in a closed state in the weekday, namely the sewage collecting pool 1 and the culture pool 7 are not communicated with each other; when in use, the two are communicated, and a large amount of culture water and excrement in the culture pond 7 enter the sewage collecting pond 1 until the liquid levels of the culture water and the excrement are level; then the channel 5 is closed, and excrement is waited to be deposited in the sewage discharge channel; and after the precipitation is finished, controlling the sewage discharge channel 2 to discharge the excrement in the sewage discharge channel and then stopping sewage discharge. And returning the rest cultivation water in the sewage collection tank 1 to the cultivation tank through a water pump and the like. If the process can adopt automatic control, the water-saving effect of the sewage discharge process is better.

In the two modes, when the water level exceeds the threshold value, the plugging object 8 is far away from the gap under the action of the floating body, so that a large amount of sediments such as excrement and the like enter the sewage discharge channel 2 through the gap to sink and gather; when sediments such as excrement and the like are removed, sewage is also removed, so that the water level is reduced, and when the water level is reduced to a threshold value, the plugging objects 8 can plug gaps; so that the sewage in the sewage collecting tank 1 can only flow out through the opening at the other end of the sewage discharge channel 2 communicated with the sewage collecting tank 1; this time, sewage can wash sewage pipes 2, and this process sewage pipes 2's displacement reduces suddenly simultaneously, means that the blowdown is accomplished, can cut off 2 exports of sewage pipes and stop blowdown drainage, gathers dirty 1 interior a large amount of relatively clean sewage that will leave of pond this moment, can use above-mentioned sewage cycle.

If the water yield of the plugging object 8 after plugging needs to be increased, the plugging object 8 can be cut off, so that when the plugging object 8 is plugged, gaps which are not shielded by part of the plugging object 8 participate in water drainage.

In addition, in order to better keep the stability of the water body environment of the culture pond, brushes and the like can be arranged in the sewage collecting pond 1, so that the nidation of microorganisms is increased, and more suspended particles are attached; meanwhile, the microorganisms of the brush fall off after death, and only fall into the sewage collecting tank 1 and the sewage discharging channel 2, and can be directly discharged, so that the influence of the microorganisms on the water environment of the culture pond is reduced.

While the present invention has been shown and described with reference to particular embodiments and alternatives thereof, it will be understood that various changes and modifications can be made without departing from the spirit and scope of the invention. It is understood, therefore, that the invention is not to be limited, except as by the appended claims and their equivalents.
