The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
It should be noted that all directional indicators (such as up, down, left, right, front, and rear … …) in the embodiments of the present utility model are merely used to explain the relative positional relationship, movement, etc. between the components in a particular posture (as shown in the drawings), and if the particular posture is changed, the directional indicator is changed accordingly.
In the description of the embodiments, the terms "disposed," "connected," and the like are to be construed broadly unless otherwise specifically indicated and defined. For example, the connection can be fixed connection, detachable connection or integral connection; can be mechanically or electrically connected; can be directly connected, can be connected through an intermediary medium, and can also be communicated with the inside of two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
As shown in fig. 1, the automatic liquid level regulation and control sewage disposal system of the culture pond of the embodiment comprises a driving motor 1, a floating ball liquid level meter 2, a floating ball protection tube 3, a sewage disposal valve 4 and a controller 5, wherein the driving motor 1 is arranged at one side of the culture pond and is connected with the floating ball liquid level meter 2 through a transmission component; wherein, the driving motor 1 can adopt a stepping motor or a servo motor, and can accurately control the lifting height of the floating ball liquid level meter 2.
The floating ball liquid level meter 2 can adopt an Islaike (ELECALL) ES series floating ball liquid level switch, and the working principle is as follows: the sealed stainless steel pipe passes through the floating ball of one or more annular magnets outside the non-magnetic permeability, one or more reed pipes are installed in the pipe, the floating ball is driven to move together when the liquid level rises and falls, when the magnet of the floating ball reaches the same horizontal position of the reed in the pipe, the reed pipe in the sealed pipe generates a sucking or breaking action, and a switching signal is output to the controller 5.
The floating ball protection pipe 3 is arranged at the inner wall of the culture pond and is partially positioned below the water surface, and the lower part of the floating ball liquid level meter 2 is positioned in the floating ball protection pipe 3; the floating ball protecting tube 3 can be made of PVC, PPR and other materials, and can protect the floating ball from being damaged by fish and shrimp.
The blow-down valve 4 is connected with the bottom of the culture pond through a blow-down pipeline 6, and a position annunciator 7 is arranged on the blow-down valve 4. Wherein, the blow-down valve 4 can adopt various valves such as a pneumatic butterfly valve, a pneumatic ball valve, an electric butterfly valve and the like; the position signal device 7 can adopt an APL series valve signal device, and the valve signal device can feed back the in-place and out-of-place signals of the sewage valve 4 into passive contact signals and display OPEN and CLOSE marks on the signal device shell.
