Description
Technical field
The utility model relates to water plug, particularly relates to a kind of piston type pumping device.
Background technique
Existing water plug is driving type water pump mostly, driving type water pump is also known as impeller type water pump or blade water pump, to the active force of liquid by atwirl impeller, mechanical energy is passed to liquid, its kinetic energy and pressure energy are increased, and then by pumping cylinder, most of kinetic energy is converted to pressure energy and realizes conveying.Centrifugal water pump is modal driving type water pump.Driving type water pump is general without suction capacity, need pumping cylinder first to be filled liquid or just can start working after being evacuated by pipeline, and in working procedure, electric energy is more converted to the kinetic energy of water, there is the shortcoming that the excessive power consumption of power is many.Existing water plug also comprises positive displacement pump, positive displacement pump has suction capacity, but in positive displacement pump extrudes liquid in pumping cylinder, the potential energy of pressure energy meeting loss part, cause the waste of energy, can not be farthest the potential energy of water the kinetic transformation of piston movement, reduce the efficiency of drawing water.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide the piston type pumping device that a kind of structure is simple, efficiency is high.
The utility model is the technological scheme solving the employing of its technical problem:
Piston type pumping device, comprise cylinder body and motor, described cylinder body is supported on the water surface by buoyancy aid, the piston plate that can pump is provided with in described cylinder body, described piston plate is provided with water outlet, described water outlet is provided with valve one, and described piston plate is connected with motor by crankshaft & connecting; The top of described cylinder body is uncovered, and is connected with water receiving disc around uncovered, and described water receiving disc is connected with outlet pipe, and lower end is connected with intake pipe, and described intake pipe is provided with valve two.
Further, described motor is submersible motor, and described submersible motor and crankshaft & connecting are arranged on below piston plate.
Further, described cylinder body is provided with two covers, and described motor is dual-axle motor, and the crankshaft & connecting of each cylinder body is connected with a rotatingshaft of dual-axle motor respectively.
Further again, described dual-axle motor and crankshaft & connecting are arranged on above piston plate, and described dual-axle motor is supported on the water surface by buoyancy aid.
Further, described valve one and valve two are the check valve that can only upwards open.
The beneficial effects of the utility model are: a kind of piston type pumping device that the utility model adopts, its conversion links is simple, the convert rotational motion of motor is the little energy that the straight line motion of piston plate additionally consumes, and in the process of transformation of energy, to the kinetic energy of Water transport and pressure energy little, and the potential energy that feedwater increases can accomplish the requirement being applicable to different water levels as far as possible, therefore the working efficiency of this device is very high, solves driving type or positive displacement water plug inevitably the problem that more electric energy conversion is by the kinetic energy that draws water or pressure energy.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model embodiment one;
Fig. 2 is the structural representation of the utility model embodiment two;
Fig. 3 is the structural representation of the utility model embodiment three.
Embodiment
embodiment one
With reference to Fig. 1, a kind of piston type pumping device of the utility model embodiment one, comprise cylinder body 1 and motor 2, described cylinder body 1 and motor 2 are supported on the water surface by buoyancy aid (scheming not shown), be provided with the piston plate 3 that can pump in described cylinder body 1, described piston plate 3 is provided with water outlet, and described water outlet is provided with valve 1, the top of described piston plate 3 is connected with crankshaft & connecting 6, and described crankshaft & connecting 6 is connected with motor 2; The top of described cylinder body 1 is uncovered, and is connected with water receiving disc 8 around uncovered, and described water receiving disc 8 is connected with outlet pipe, and lower end is connected with intake pipe 7, and described intake pipe 7 is provided with valve 25.Need further illustrate, described valve 1 and valve 25 are the check valve that can only upwards open.
Working principle of the present utility model is: be placed on by water plug in water, and under the effect of hydraulic pressure, water to enter in cylinder body 1 and washes valve 25 open, is stored in below piston plate 3; Piston plate 3 is toward when pressing down in cylinder body 1, and valve 25 is closed, and valve 1 is rushed to open, and water rises to above piston plate 3; When piston plate 3 up promotes in cylinder body 1, valve 1 is closed, valve 25 is rushed to open, under external atmosphere pressure effect, water is drawn in cylinder body 1 from intake pipe 7 by valve 25, and be formerly promoted to water on piston plate 3 from being directly spilled over to water receiving disc 8, then by the outlet pipe of water receiving disc 8, water drawn.Such piston plate 3 pumps in cylinder body, constantly draws water.
The utility model is arranged to the top of cylinder body 1 uncovered, the water from uncovered spilling is received again by water receiving disc 8, this set is the pressure energy of water in order to reduce in process that piston plate 3 promotes the potential energy of water, thus the kinetic transformation farthest piston plate 3 moved is the potential energy of water, reach the object improving efficiency of drawing water.
embodiment two
With reference to Fig. 2, a kind of piston type pumping device of the utility model embodiment two, it is with the difference of embodiment one: described motor 2 is submersible motor, and described submersible motor and crankshaft & connecting 6 are arranged on below piston plate 3.
embodiment three
With reference to Fig. 3, the described cylinder body of the utility model embodiment three is provided with two covers, and described motor 2 is dual-axle motor, and the crankshaft & connecting 6 of each cylinder body is connected with a rotatingshaft of dual-axle motor respectively.The present embodiment drives a cylinder body job respectively by two output shafts of dual-axle motor, and compared with embodiment one, its efficiency of drawing water is higher.
The utility model is placed in water and works, because it has suction capacity, and the potential energy loss therefore can energy-conservationly drawn water.Be the straight line motion of piston plate 3 the convert rotational motion of motor 2 by crankshaft & connecting 6, thus water is risen to certain position the water surface from underwater certain position, realize circulation and draw water.The conversion links of the energy of this device is simple, the convert rotational motion of motor 2 is the little energy that the straight line motion of piston plate 3 additionally consumes, and in the process of transformation of energy, to the kinetic energy of Water transport and pressure energy little, and the potential energy that feedwater increases can accomplish the requirement being applicable to different water levels as far as possible, therefore the working efficiency of this device is very high, solves driving type or positive displacement water plug inevitably the problem that more electric energy conversion is by the kinetic energy that draws water or pressure energy.
The above, just better embodiment of the present utility model, but the utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, all should fall within protection domain of the present utility model.
