Wave-driven steam vertical exchange device

Abstract

The invention discloses a wave-driven steam vertical exchange device. The device comprises a floating box with an air vent; a support is arranged on a side wall of the floating box; a transverse connecting rod with a gear on the end part is mounted on the support; one end of a volute spiral spring is mounted on the connecting rod and the other end of the volute spiral spring can freely penetrate into and out of a non-elastic rope of a bottom wall of the floating box to be connected with an anchor jaw outside the floating box; an outer barrel is mounted on the bottom wall of the floating box, the bottom of the outer barrel stretches out of the floating box and a thread is arranged on an inner side wall; a water inlet is formed in a side wall of the outer barrel; an inner barrel is arranged in the outer barrel; a toothed rod, which is engaged with the gear of the connecting rod, is mounted at the top of the inner barrel; a rotor is arranged at each of the upper part and lower part of the inner barrel in a sleeving manner; a turbine is arranged in each rotor. According to the exchange device disclosed by the invention, waves can drive the rotors to move up and down along the thread of the inner side wall of the outer barrel and rotate, and the turbines in the rotors are used for filling air into a lower-layer water body through an air outlet pipe; meanwhile, water with high oxygen content in the lower-layer water body is led into a lower-layer oxygen-poor water body through a water feeding pipe and a unidirectional water valve; oxygen filling and water filling can be automatically carried out on the lower-layer water body at the same time by utilizing the waves.

Description

technical field [0001] The invention belongs to the field of water quality improvement equipment, in particular to a wave-driven water-air vertical exchange device in the field. Background technique [0002] Dissolved oxygen in water is an important indicator to measure water quality. If the oxygen concentration is too low, the water environment will deteriorate, and the deterioration of water quality will also pose a threat to the survival of aquatic organisms. Oxygen content is highest in surface water bodies, and the concentration of dissolved oxygen decreases with increasing water depth. In order to increase the oxygen content in water, the methods that have been widely used at present are: one is to use electric energy to oxygenate the water; the other is to use electric energy to exchange the upper water body and the lower water body. These methods consume electric energy and fail to meet the requirements of environmental protection. In addition, there are devices tha...

Problems solved by technology

These methods all consume electric energy and fail to meet the requirements of environmental protection. In addition, there are devices that use floats for oxygenation or exchange of upper and lower water bodies. Although these devices do not consume electric energy, they have low efficiency and poor working effect.
