Water feeding and drainage equipment for aquaculture pond

Abstract

The invention discloses water feeding and drainage equipment. The equipment is structurally provided with a rear drive machine, a front suction end, a clamping cover, a water inlet, a water outlet and supporting feet, wherein the supporting feet are fixedly connected to the lower portion of the rear drive machine in an embedded mode, the front suction end is arranged at the front end of the rear drive machine and matched with the rear drive machine, the clamping cover is movably clamped to the front end of the front suction end, the water inlet and the clamping cover are of an integrated structure and communicate with each other, and the water outlet is arranged in the top of the front suction end in a penetrating mode. A movable ring body is integrally of an annular structure, and when centrifugal air pressure acts on the movable ring body, the movable ring body can clamp an annular wall block to move, impurities are contained in an arc pocket shape of a cavity containing channel, a cavity ball is driven by a gravity ball to move up and down, the change of air flow at the end opening of the cavity containing channel is assisted, the absorption of the impurities is facilitated, the impurities enter a carrying cavity through a rear through path in the through opening state, are shaken out again from a front through end under the inertia effect in the annular motion process of the movable ring body and move along with airflow, and therefore the impurities are not prone to being attached to the inner ring wall of an air pressure cavity.

Description

technical field [0001] The invention belongs to the field of drainage, and more specifically relates to a water inlet and drainage device for aquaculture ponds. Background technique [0002] The aquaculture industry is a major industry in my country's economic development. Aquaculture has high requirements for water quality, so it is often necessary to use a pump to replace the water source of the aquaculture pond. The pump can convert its own mechanical energy into liquid energy and form a vacuum at the inlet. Negative pressure state, transporting water from one place to another, is widely used in pumping and drainage operations. [0003] Based on the above-mentioned inventor's discovery, there are following deficiencies in the existing aquaculture pond inlet and drainage equipment: [0004] Because the excess bait and fish excrement in the water will produce nitrite, when the pump is draining the aquaculture pond, the rotating motion of the impeller will form a vacuum low-...

AI Technical Summary

Problems solved by technology

[0004] Because the excess bait and fish excrement in the water will produce nitrite, when the pump is draining the aquaculture pond, the rotating motion of the impeller will form a vacuum low-pressure area at the center of the impeller shaft blade, which will affect the The water in the culture pond has air pressure adsorption, the water quality is sucked into the diffusion chamber of the pump chamber, and the rotating centrifugal force generated by the impeller throws it out, so that it can be squeezed out from the drain, and when the nitrite is absorbed with the water quality, it is easy Due to the inertial force, it rushes into the vacuum resistance area, and then adheres to the inner ring wall of the low pressure area, accumulating into dirt, resulting in a smaller area of ​​the low pressure area, which reduces the efficiency of water absorption.
