Description

Floating pump

Technical Field

The invention belongs to the technical field of water pump equipment, and particularly relates to a floating pump.

Background

Water pumps are machines that deliver or pressurize a liquid. It transfers the mechanical energy of prime mover or other external energy to liquid to increase the energy of liquid, and is mainly used to transfer liquid including water, oil, acid-base liquid, emulsion, suspoemulsion and liquid metal. Liquids, gas mixtures, and liquids containing suspended solids may also be transported. The floating pump floats in the surface of water, and the water inlet is generally less than surface of water 25~50 centimetres, and the advantage is not influenced by water bottom mud sand for among the aquaculture, through the process of spraying the culture water, with culture water and air abundant contact, increase the oxygen content in the culture water.

Currently available water oxygenating machines for environmental protection are broadly divided into two types: first, lifting, waterwheel type, etc.: the existing products sink the floating water pump in shallow water or float on water fixedly, but have the disadvantages that the floating water pump cannot be controlled to move in rivers, lakes and ponds, and can only be fixed for use, so that the phenomenon that the power consumption and oxygen increase are avoided at the position, the ecological restoration of the river is not facilitated, and the floating water pump is easy to damage and not easy to maintain when exposed to various climatic conditions; II, aeration boat type: the power is high, but the power can not play a role in a river channel with a shallow river and a narrow culvert and dense arrangement in a water area upstream of a branch, the noise is loud, the normal life of residents can be interfered when the power is used, and the use cost is quite expensive. And the two water oxygenation machines have single functions, so that the environment-friendly machine with low cost and wide application is needed for ecological restoration and sewage treatment of the river channel.

Because the emergency flood drainage and emergency rescue has many specificities, such as the emergency of an event, the urgency of emergency rescue, the complexity of a working face, the safety of operation, the randomness of construction environment, the environmental protection of a working site, the arbitrariness of time, the long continuous working time and the like, the emergency flood drainage and emergency rescue also puts forward higher and more professional requirements on corresponding equipment.

However, the existing floating water pump still has some unreasonable factors in the process of increasing the oxygen content in the culture water, and when the existing floating water pump is used: the position close to the water surface in the culture water generally contains more organisms such as algae, water fleas and the like, the organisms are sucked into the water pump box by the floating pump and then are sprayed out through the fan-shaped nozzle, and the organisms such as the larger algae, water fleas and the like easily block the fan-shaped nozzle, so that the fan-shaped nozzle cannot spray out the water in the culture pond, the load of the motor is increased, and the motor can be burnt when the water is serious; when the existing floating water pump is used, the connecting rope of the fixing anchor of the floating water pump is long, the floating water pump is not convenient to store and release, the connecting rope is easy to tie, and the like.

The work of drawing water can only be carried out at the bank to the water pump for portable structure usually, because bank depth of water is more shallow and prolong the weeds debris many, the water pump inhales silt or debris very easily, causes certain damage, and the radiating effect is poor to the not convenient for remove when dealing with the drainage and speedily carrying out rescue work, to this patent number: CN201811025219.1 discloses a representative floating pump, which floats on the water surface through a floating body, and can make the sucked water flow exchange heat with the surface of a driving motor, so as to improve the heat dissipation effect of the motor, but its filtering system is not perfect enough, and it is easy to suck impurities to cause the filter screen to be blocked when the water quality is poor, thereby affecting the water pumping efficiency.
