Abstract
Description
Technical fields:
[0001] This utility model belongs to the field of fish pond sewage technology, and more specifically relates to an auxiliary device for fish pond sewage discharge. Background technology:
[0002] In fishpond aquaculture, maintaining clean water and promptly removing feces and uneaten feed are crucial for the healthy growth of fish. Traditional fishpond waste disposal methods are often inefficient and fail to effectively remove accumulated waste from the bottom, leading to water quality deterioration and impacting fish growth and their living environment.
[0003] National invention patent No. 201210024441.6 discloses an automated aquaculture system. It describes a circular aquaculture pond with an inverted conical bottom and a drain outlet at the pointed top to collect and discharge waste. A water level controller automatically controls the water inlet to maintain a constant water level. An automatic feeder is installed to feed the fish at fixed times, quantities, and locations. A submersible pump is placed inside the pond to automatically rotate the water at regular intervals, collecting waste at the bottom. An automatic timed valve is installed at the drain outlet to quantitatively remove waste from the bottom. While this system effectively solves the above problems, the swirling current formation method is relatively simple, resulting in uneven distribution of the swirling current. The effect of carrying and concentrating waste in areas such as the corners of the pond is poor, leading to incomplete waste removal. Utility Model Content:
[0004] To solve the above problems and overcome the shortcomings of the existing technology, this utility model provides an auxiliary device for fish pond sewage discharge;
[0005] The first technical problem to be solved was that the vortex distribution was not uniform enough, and the effect of moving and concentrating waste in areas such as the corners of the fishpond was not good, resulting in incomplete sewage discharge.
[0006] The specific technical solution of this utility model to solve the above-mentioned technical problems is as follows: the fish pond sewage discharge auxiliary device includes an annular water tank, and a sewage outlet is provided at the bottom of the annular water tank.
[0007] A circulating water tank connected to the annular water tank is provided on one side of the annular water tank. A grid is provided between the circulating water tank and the annular water tank. A water pump is provided in the circulating water tank to draw liquid from the circulating water tank into the annular water tank. The outlet end of the water pump is sealed and connected to a guide pipe. The guide pipe extends from the circulating water tank into the annular water tank and is connected to an outlet pipe. The outlet pipe is inserted vertically into the bottom of the annular water tank. A predetermined number of holes are evenly opened on the wall of the outlet pipe located in the annular water tank. The holes are tangentially arranged along the inner wall of the annular water tank.
[0008] Furthermore, the grid between the annular water tank and the circulating water tank is detachable.
[0009] Furthermore, the grid mesh is provided with locking blocks on both sides of the grid mesh, and the water tank is provided with a locking groove that matches the locking blocks at the contact point with the grid mesh.
[0010] Furthermore, a filter screen is installed at the water inlet of the water pump.
[0011] Furthermore, the bottom of the annular water tank is provided with a fixed base for fixing the guide pipe, and the fixed base is fixed to the bottom wall of the annular water tank by bolts.
[0012] Furthermore, a flow-turbulence structure is connected between the guide pipe and the outlet pipe. The flow-turbulence structure includes a flow-turbulence pipe, both the upper and lower ends of which are fixedly connected to the guide pipe. A flow-turbulence seat and a fixed seat are provided inside the flow-turbulence pipe. The fixed seat is fixedly installed inside the flow-turbulence pipe and is located above the fixed seat. It is rotatably installed with the fixed seat via a rotating shaft. Several spiral blades are arranged around the side wall of the flow-turbulence seat.
[0013] Furthermore, the sidewall of the fixed base is provided with several connecting arms, and the two ends of the connecting arms are respectively connected to the inner wall of the turbulence tube and the fixed base.
[0014] Furthermore, the rotating shaft is embedded inside the spoiler seat, and the lower end of the rotating shaft is fixedly connected to the fixed seat.
[0015] Furthermore, a diverter seat is fixedly disposed above the spoiler seat. The diverter seat has a pointed shape, and the end of the diverter seat away from the pointed end is fixedly connected to the spoiler seat.
[0016] The beneficial effects of this utility model are:
[0017] One advantage of this invention is that a circulating water tank is connected to one side of the annular water tank. A water pump is installed in the circulating water tank to draw liquid from the circulating water tank into the annular water tank. The outlet end of the water pump is connected to a guide pipe and an outlet pipe. The outlet pipe is inserted vertically into the annular water tank. Holes are evenly distributed on the wall of the outlet pipe, tangentially arranged along the inner wall of the annular water tank. Through the tangential jet method and swirling design, centrifugal force can be used more efficiently to push feces and uneaten food towards the pool wall and settle to the bottom, solving the problem of incomplete sewage discharge in traditional fish ponds.
[0018] One advantage of this invention is that a detachable grid is provided between the circulating water tank and the annular water trough. The grid is used to prevent fish from entering the circulating water tank and can also initially filter larger particles of impurities. Furthermore, through the cooperation of the slots and blocks, it can be quickly installed and removed, thereby cleaning the grid.
[0019] One advantage of this invention is that it provides a turbulent structure connecting the guide pipe and the outlet pipe. The spiral blades rotate under the action of the water flow, and the spiral blades guide the water flow to generate rotation and cross motion. The originally relatively stable laminar flow is broken and irregular turbulence is formed, which greatly enhances the internal energy and scouring force of the water flow. This makes the impact and driving effect of the water flow ejected from the water pipe hole on the waste in the fish pond stronger, and further improves the sewage discharge efficiency.

In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0027] The specific embodiment of this utility model is as follows: A fish pond sewage discharge auxiliary device includes an annular water tank 1, the bottom of the annular water tank 1 is conical, and a sewage outlet 11 is provided at the tip of the water tank.
[0028] As the inventive point of this utility model
[0029] A circulating water tank 2 connected to the annular water tank 1 is provided on one side. A grid mesh 3 is provided between the circulating water tank 2 and the annular water tank 1. The grid mesh 3 is used to prevent fish from entering the circulating water tank 2 and can also initially filter larger particles of impurities.
[0030] Preferably, the grid 3 between the annular water tank 1 and the circulating water tank 2 is detachable, which facilitates the periodic cleaning of debris attached to the grid 3 and ensures smooth water flow. The grid 3 is provided with locking blocks 31 on both sides of its edge, and the water tank and the grid 3 are provided with locking grooves 12 that are compatible with the locking blocks 31. The locking grooves 12 and the locking blocks 31 cooperate to achieve quick installation and disassembly.
[0031] The circulating water tank 2 is equipped with a water pump 21 that draws liquid from the circulating water tank 2 into the annular water tank 1. A filter screen is installed at the suction port of the water pump 21, and a guide pipe 22 is sealed to the outlet end of the water pump 21. The guide pipe 22 extends from the circulating water tank 2 into the annular water tank 1 and is connected to an outlet pipe 4. The outlet pipe 4 is inserted vertically into the bottom of the annular water tank 1. A fixing base 13 is provided at the bottom of the annular water tank 1 to fix the outlet pipe 4. The fixing base 13 is fixed to the bottom wall of the annular water tank 1 by bolts to prevent the outlet pipe 4 from shaking under the impact of water flow.
[0032] A predetermined number of holes 41 are evenly opened on the wall of the water outlet pipe 4 located in the annular water tank 1. The holes 41 are arranged tangentially along the inner wall of the annular water tank 1 so that the water flow can form a swirling flow and improve the impurity cleaning effect.
[0033] Preferably, a flow-disrupting structure 5 is connected between the guide pipe 22 and the outlet pipe 4. The flow-disrupting structure 5 includes a flow-disrupting pipe 51. The upper end of the flow-disrupting pipe 51 is connected to and fixedly installed with the guide pipe 22, and the lower end of the flow-disrupting pipe 51 is connected to and fixedly installed with the outlet pipe 4. A flow-disrupting seat 52 and a fixing seat 53 are provided inside the flow-disrupting pipe 51. The fixing seat 53 is fixedly installed inside the flow-disrupting pipe 51. Preferably, a plurality of connecting arms are arranged around the side wall of the fixing seat 53, and the two ends of the connecting arms are respectively connected to the inner wall of the flow-disrupting pipe 51 and the fixing seat 53.
[0034] The turbulence-disrupting seat 52 is disposed above the fixed seat 53 and is rotatably disposed with the fixed seat 53 via a rotating shaft 55. The rotating shaft 55 is embedded inside the turbulence-disrupting seat 52, and the lower end of the rotating shaft 55 is fixedly connected to the fixed seat 53. Several spiral blades 521 are arranged around the side wall of the turbulence-disrupting seat 52. Preferably, a diverter seat 54 is fixedly disposed above the turbulence-disrupting seat 52. The diverter seat 54 is pointed, which reduces the resistance to the water flow in the guide pipe 22 and does not affect the water flow velocity. The end of the diverter seat 54 away from the pointed end is fixedly connected to the turbulence-disrupting seat 52.
[0035] It should be noted that this utility model is an auxiliary device for fish pond sewage discharge. In specific operation,
[0036] (1) Turn on the water pump 21. After the water pump 21 pressurizes the water it draws in, it transports the liquid in the circulating water tank 2 to the outlet pipe 4 through the guide pipe 22 which is connected to it by a sealing thread. The liquid is then transported to the annular water tank 1 through the outlet pipe 4.
[0037] The outlet pipe 4 has evenly distributed holes 41 tangentially along the inner wall of the annular water tank 1, allowing water to be injected tangentially into the annular water tank 1 at high speed. These tangential water flows interact within the annular water tank 1, causing the water in the entire annular water tank 1 to form a stable vortex.
[0038] Meanwhile, since there is a turbulence structure 5 connecting the guide pipe 22 and the outlet pipe 4, when the water flows through the turbulence structure 5, the water first contacts the diverter seat 54. The pointed design of the diverter seat 54 allows the water to be smoothly dispersed to the turbulence seat 52. The spiral blades 521 of the turbulence seat 52 rotate under the action of the water flow. The spiral blades guide the water flow to generate rotation and cross motion. The originally relatively stable laminar flow is broken, forming irregular turbulence, which greatly enhances the internal energy and scouring force of the water flow. This makes the impact and driving effect of the water flow ejected from the water pipe hole 41 on the waste and impurities in the annular water tank 1 stronger, further improving the sewage discharge efficiency.
[0039] (2) Under the combined effect of swirling and turbulent flow, waste such as feces and uneaten food in the annular tank 1 is pushed towards the tank wall by centrifugal force. Due to the relatively high density of these wastes, they gradually move towards the tank wall of the annular tank 1 under the combined influence of centrifugal force and water flow friction. As time goes by, the waste accumulates near the tank wall and begins to settle.
[0040] (3) Waste that settles to the bottom is guided by the slope at the bottom of the annular water tank 1 to the sewage outlet 11. The sewage outlet 11 is opened manually at regular intervals, and the accumulated waste is discharged from the fish pond by the gravity of the sludge itself, thereby cleaning the pollutants at the bottom of the annular water tank 1, ensuring the normal operation of the annular water tank 1, and thus maintaining the efficient and stable operation of the entire water circulation and sewage system; the grid screen 3 can be removed by manually pulling the clips 31 on both sides of the grid screen 3 out of the slots 12, thereby cleaning the impurities attached to the grid screen 3 and ensuring smooth water flow; the filter screen of the water pump 21 suction port is cleaned regularly to prevent debris from clogging and affecting the pumping efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
