Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to an improved automatic sewage discharge device for high-position pond aquaculture. Background Art

[0002] In the breeding of fish, shrimp and other aquatic products in high-level ponds, sewage discharge operations are often required. During the process of oxygenation, the impeller aerator in the high-level pond will stir the water body, causing the pond water body to form a circular water flow. Under the action of centrifugal force, the residual bait and feces at the bottom of the pond and the aging and dead algae will gather in the center of the pond. Since high-level ponds generally raise fish, shrimp and other aquatic products with high density, the load of the high-level pond is also relatively heavy, so a large amount of sewage needs to be discharged from the pond every day.

[0003] The existing sewage discharge method generally involves building a sewage discharge channel with a horizontal plane lower than the bottom of the high-level pool, connecting the sewage discharge channel to the bottom of the high-level pool with a PVC pipe, inserting a water pipe with a vertical height exceeding the water level of the high-level pool into the sewage outlet of the PVC water pipe end of the sewage discharge channel, and wrapping a filter net around the PVC water pipe end at the bottom of the high-level pool. When discharging sewage, it is necessary to manually pull the vertical water pipe out of the PVC pipe to automatically discharge sewage. After the sewage is discharged, it is necessary to manually insert the vertical water pipe into the PVC pipe again to balance the water level and stop the sewage discharge. In this way, the labor intensity of workers pulling out and inserting the pipe is high, and there are also risks such as damage and consumption caused by poor pulling out and inserting, and the risk of workers falling due to hydraulic resistance when inserting the pipe. For this purpose, our company has developed an automatic sewage discharge device for high-level pond aquaculture with patent number: CN202320785641.7, which includes a controller, a water level balance pipe, a pipe cap, a driving mechanism, a piston and a push rod. The water level balance pipe is located at one end connected to the sewage discharge pipe and is provided with at least one water outlet. The pipe cap is provided on the top of the water level balance pipe. The driving mechanism is provided on the bottom of the pipe cap and is located in the water level balance pipe. The output end of the driving mechanism is connected to the other end of the push rod to drive the push rod to move up and down, thereby driving the piston to rise and open the various water outlets of the water level balance pipe for sewage discharge or descend to block the various water outlets of the water level balance pipe to stop sewage discharge. The piston is provided with a perforation for connecting the upper part of the water level balance pipe with the sewage discharge outlet of the sewage discharge pipe at the bottom of the high-level pond. The driving mechanism is connected to and controlled by the controller. This utility model solves the problem that the existing high-level pond aquaculture cannot effectively discharge sewage automatically and the labor intensity of workers is high. The device realizes automatic sewage discharge, but there is no way to effectively know whether the sewage discharge device is operating normally and its operating status, and personnel need to be arranged to conduct regular inspections. When the sewage discharge device fails, it cannot be known in time and handled in time, causing losses to high-level pond aquaculture. Utility Model Content

The push rod and the piston can be moved up and down in the water level balance pipe and one end of the push rod is connected to the piston. The output end of the driving mechanism is connected to the other end of the push rod to drive the push rod to move up and down, thereby driving the piston to rise and open the various water outlets of the water level balance pipe for sewage discharge or to descend to block the water level balance. Each water outlet of the balance pipe stops discharging sewage, and the piston is provided with a perforation for connecting the upper part of the water level balance pipe with the sewage outlet of the sewage pipe at the bottom of the high-level pool.

The displacement sensor is arranged in the water level balance pipe to detect the position information of the piston and send the detection information to the controller. The controller is connected to the smart phone APP end through the communication module.

[0006] A further improvement includes an expansion piece, which is arranged on the inner wall of the water level balance tube at the side of the water outlet, and a notch matching the expansion piece is provided on the lower edge of the piston side wall at the corresponding position of the expansion piece, and a groove is provided on the piston side wall extending upward from the upper end of the notch to the top.

[0007] As a further improvement, the expansion piece is triangular in shape, and the notch on the lower edge of the piston side wall is an inverted V-shaped notch that matches the expansion piece.

[0008] As a further improvement, a positioning block is provided on the inner wall of the water level balance tube at the slot of the piston for guiding and positioning the piston when it moves up and down.

[0009] As a further improvement, the middle portion of the push rod is sleeved on the centering plate, and the outer diameter of the centering plate is matched with the inner diameter of the water level balance pipe.

[0010] As a further improvement, the piston is cylindrical in shape, and the outer diameter of the piston is matched with the inner diameter of the water level balance tube, and the perforations of the piston are perforations arranged parallel to the central axis and at intervals.

[0011] As a further improvement, the push rod is fixedly connected to the middle part of one end of the piston, and the various perforations of the piston are arranged at intervals around the connection with the push rod.

[0012] As a further improvement, the piston is in the shape of a hollow cylinder, and the outer diameter of the piston is matched with the inner diameter of the water level balance tube, and the perforation of the piston is a hollow cavity in the shape of a hollow cylinder.

[0013] As a further improvement, a cross positioning frame is further provided on the upper part of the water level balance pipe, and a limiting hole is provided at the center of the cross positioning frame for the push rod to pass through and to limit the push rod in the vertical direction.

[0014] A further improvement includes a control box, in which the controller and the communication module are both arranged. The control box also includes a power supply and a control panel.

[0015] As a further improvement, the driving mechanism is a pneumatic cylinder or a hydraulic cylinder or a screw motor or a push rod motor.

The pool can be troubleshooted to avoid losses. At the same time, there is no need to arrange manual inspections of each high-level pool to check whether common faults such as water level exceeding the limit, power failure, and overtemperature occur. Through further settings, that is, the expansion piece and the notch structure matched with the expansion piece arranged on the piston cooperate, the expansion piece makes the piston close to and seals the outlet of the water level balance pipe, thereby effectively preventing water leakage. The setting of the center plate on the push rod enables the push rod to be supported by the center plate, effectively ensuring that the push rod is not easy to bend and prolonging its service life. The setting of the cross positioning frame effectively prevents the push rod from being offset, further ensuring the stability of the piston and push rod structure, and setting the piston to a cylindrical shape matched with the water level balance pipe makes the piston better at sealing the outlet of the water level balance pipe, and the overall structure cooperates more smoothly. The control panel is set to facilitate the setting of automatic sewage discharge control or manual sewage discharge, system timed sewage discharge, etc., which can be widely promoted and applied.
