Automatic water changing device applied to small landscape water body in gardening industry

Abstract

The invention discloses an automatic water changing device applied to a small landscape water body in a gardening industry. The device comprises a shell, wherein a water storage cavity is disposed inthe shell, a first water inlet pipe passing through the upper surface of the shell is disposed in the top wall of the water storage cavity, a first ball valve is in rotatable connection inside the first water inlet pipe, a first rotation shaft is in rotatable connection inside the right wall of the first water inlet pipe, and the left end of the first rotation shaft is fixedly connected to the right side face of the first ball valve. The device is simple in structure and convenient to use, and can control opening or closing of the ball valve in the water inlet pipe by a buoyancy ball accordingto the quantity of added tap water so as to ensure the certain quantity of water added each time. The device can realize automatic adding of dechlorination tablets, and use another buoyancy ball to ensure basic equivalency of the quantity of former water pumped out and the quantity of fresh water added so as to ensure the ecological environment in the landscape water body does not change obviously.

Description

technical field [0001] The invention relates to the technical field of landscape gardens, in particular to an automatic water exchange device for small landscape water bodies in the garden industry. Background technique [0002] For landscape fish, especially those living in small-scale water bodies, fish excrement, scattered food residues, etc. decompose into ammonia after decay in the water, and fish are easily poisoned, so the water needs to be changed frequently. Fresh tap water is very different from the environment in which fish live. Tap water needs to be dechlorinated before it can be used. The old water is light green or light amber, rich in humus and beneficial microorganisms and algae, and has established a good ecological cycle system. After the nitrogen cycle, it is decomposed into nitrates that are harmless to fish. This kind of water is extremely beneficial to the growth of fish. [0003] When changing the water, generally only one-third needs to be changed,...

Problems solved by technology

Most of the existing technologies use ecological filtration to automatically purify impurities in the water body, but for small landscape fish, because there is no too complicated ecological structure, this method is not suitable, and the cost is too high, while other The advanced water changing equipment cannot realize the automatic addition of chlorine removal agents, nor can it ensure that the amount of old water discharged and the amount of new water added remain constant, and there is some inconvenience in use.
