Abstract

The present invention relates to a floating movement pump which is self-provided with a motor to move in a large range to irrigate. The present invention comprises a motor and a water pump connected with a power output shaft, wherein the motor and the water pump form a whole machine body; the water pump has a water-sucking inlet positioned under a light waterline in operation and a water outlet butted to a water outlet pipe. One group of two or more than two dismountable floats are fixed around the water pump, which leads that the motor can be correspondingly and fully exposed out of the floats, and a radiation effect in the air can be improved; the whole machine body and each floats can be detached, which leads that repair and maintenance are more convenient more than the prior art; simultaneously, one part of the whole machine body, which is under water, is in water but not separated from water by the floats, and water-cooling heat dissipation is realized.

Description

Float pump

Technical field

The present invention relates to a kind of agriculture sprinkling machine, in irrigation canals and ditches, carry the float pump that motor carries out moving sprinkling irrigation on a large scale.

Background technique

There is the large size crop at water sources such as irrigation canals and ditches to spray to neighbouring, the movable sprinkler irrigation machineries that adopt more, particularly equipment can tow in water, and the operator is the traveling sprinkler of handheld spray head operation on the coast, is extensive use of owing to having distinguishing feature easy to use.

Known this class traveling sprinkler has multiple, the CN2361075Y that is called " light float-moving type rainer " as name, name is called the CN2395536Y of " the portable irrigation rig of dense waterway net region ", name is called the CN2406478Y of " the small-sized mobile irrigation emitter unit of keeping afloat " and the CN2549726Y that name is called " a kind of amphibious irrigation sprinkler ", the each have their own characteristics of these innovation and creation, but the common ground that has is: a big shedding shell that buoyancy is provided is arranged, the complete machine body that motor (or motor) and pump constitute is positioned at housing, only is in water hermetically between mouth piece and housing.Thereby the common problem that exists is, in the very little originally housing of volume once during water inlet, just must outwards wash in a pan water to satisfy buoyancy; Sealing technology between housing and mouth piece is had relatively high expectations, and sealing part leakage problems in housing often takes place; The complete machine body is positioned at the space that housing wall and the end surround, and motor is considered the heat radiation requirement because of bad by the barrier radiating effect during design, and motor must satisfy the certain distance requirement apart from inner walls, and housing thereby size are bigger, and noise is very big; Motor or pump need repairing or maintain time dismounting inconvenience; From little, the lightweight designing requirement of volume, housing many with heat resistance preferably glass fibre reinforced plastics make, glass steel shell can only carry out by hand, manufacturing efficiency is extremely low.

Summary of the invention

The float pump that main purpose of the present invention provides a kind of complete machine body excellent in heat dissipation effect, installation and maintenance is convenient, be suitable for producing in enormous quantities, volume is littler;

Another object of the present invention provides a kind of more reasonable structural design, float pump that operating noise is low;

A further object of the present invention provides the float pump that a kind of unsinkability is improved.

For achieving the above object, the float pump that the present invention provides comprises providing driving the motor that pump working power has pto, refutes the water pump and the motor that are connected on the pto and constitutes the complete machine body.The water outlet that is positioned at the following water sucking mouth of lightwaterline when water pump has work and docks with outlet pipe, the water sucking mouth underwater when this can guarantee that fuel oil is full, also can guarantee the water sucking mouth under waterline under the situation of complete machine come-up when fuel oil exhausts, prevent that suction from taking place.The dismountable one group of buoyancy aid more than two or two that comprises fuel tank around be fixed on water pump around, this makes motor be able to be exposed at relatively fully the buoyancy aid outside, improve aerial radiating effect, therefore, buoyancy aid can be processed with blow molding process with the heat resistance plastics low than glass fibre reinforced plastics, the manufacturing efficiency height, detachable design between complete machine body and each buoyancy aid, make maintenance convenient than prior art, simultaneously, complete machine body part underwater is in water, rather than by buoyancy aid that water is isolated, has improved the air cooling heat dissipation environment of motor.Because the design of such scheme improves engine radiating, can make the volume of buoyancy aid littler.

For making structural configuration more reasonable, the fuel tank of motor can be arranged and be improved, being designed to the relative complete machine body weight heart is the fuel tank that is arranged symmetrically in complete machine body both sides, and the major part of fuel tank is positioned at underwater, because of the proportion of fuel oil little than water, fully loaded fuel tank still can provide buoyancy, fuel tank has the air duct that is positioned on the waterline, along with the consumption of fuel oil, replenishes the air that enters gradually the buoyancy that increases gradually can be provided.Between the fuel tank of every pair of symmetric arrangement the fuel gallery is arranged, this can be avoided bringing because of fuel consume the problem of centre-of gravity shift.For improving unsinkability, every buoyancy aid can be designed to have at least a no big hatch frame that the buoyancy tank of buoyancy is provided.

Motor has the problem of body heat radiation on the one hand, on the other hand, its heat that distributes by baffler also accounts for very big proportion, traditional baffler design is arranged in the air, for improving the thermal diffusivity of motor on outlet pipe more, the present invention designs the baffler of motor in water, this makes it can provide buoyancy on the one hand, and on the other hand it being changed air cooling is water-cooled, has improved the radiating effect of motor greatly.The mouth of pipe of giving vent to anger of baffler can be designed to exceed waterline, and is in line in air, or the stage casing exceeds the structural type that waterline mouth end is in water.
