Technical Field

The invention relates to a water pumping device, in particular to a piston type water pump for lifting various liquids.

Background

To date, various water lifting pumps, namely water pumps, are directly driven by power, and have the defects of more energy consumption, such as water pumping and energy storage power generation, according to the prior art, one kilowatt of electric energy is used for pumping water from a low position to a high position and storing the water in a pond or a reservoir, and the electric quantity generated by water discharging power generation cannot exceed 0.75 kilowatt at most, namely one quarter of the loss is caused.

Disclosure of Invention

The invention aims to overcome the defects and provide a water lifting pump with higher water lifting efficiency, for example, one kilowatt of electric energy is used for pumping water from a low position to a high position and storing the water in a pond or a reservoir, the electric quantity generated by water discharge and power generation can reach more than two kilowatts, and the technical scheme is adopted for realizing the purpose.

At least two lifting piston rods are vertically installed, the lower end tops of the lifting piston rods are sleeved with pistons which are positioned in a cylinder sleeve, the upper end tops of the lifting piston rods are slopes with high outer parts and low inner parts, the two piston rods are overlapped in tandem, the two overlapped piston rods are connected with each other by a same pull rope, the middle section of the pull rope is lapped and wound in an annular groove at the outer edge of a turning pulley which can rotate in situ and is respectively arranged at the left upper part and the right upper part in the longitudinal direction, when the lifting piston rods are lifted in place, the outer edges of the left slope and the right slope in the transverse direction are flat rails on the same level, the lower edges of the two rollers driven by power are respectively attached to the flat rails on the same level as the outer edges of the left slope and the right slope in the transverse direction and roll back and forth along the flat rails, a pressing wheel which is smaller than the rollers is sleeved on the same flat shaft of the rollers and is opposite to the slopes, a balance weight is sleeved, others are unchanged.

The working process and working principle are as follows: the two rollers driven by power are driven to roll and move back and forth, the lifting type slopes on the front side are pressed by the pressing wheels in the rotation process, the same pull rope is used for connecting the lifting type piston rods on the lower sides of the two slopes, at least two slopes are connected at the same time, the piston rods and the pistons fall down and rise up one by one, the front side falls down to form resistance to the rollers, the back side rises up to form thrust to the rollers, namely power, the resistance and the thrust are equal to each other and offset from each other, the slope rises and falls, the lower sides are connected with the piston rods connected into a whole, the piston rods which rise to form suction force are lifted synchronously, the switch on the lower side of the cylinder sleeve is lifted to suck water into the cylinder sleeve, the switch on the lower side of the cylinder sleeve which falls to form pressure is closed to discharge the water out.

Because the weight of the roller is more than nine times that of the roller is borne by the slope in the back-and-forth rolling movement of the roller, only a small amount of power falls on the track, the power required by the rolling movement is very small, the larger the diameter of the roller with the same weight is, the more easily the roller is pulled (pushed), and the minimum power required in the rolling movement is less than 0.01 of the weight of the roller, so that the power is replaced by pressure, namely the power is changed into pressure, and then the pressure is converted into the power, so that the original matched power is amplified by several times to tens of times.

In summary, the technical scheme adopted by the invention has the key points that: at least two lifting piston rods are vertically installed, pistons are sleeved at the lower end tops of the lifting piston rods and are positioned in a cylinder sleeve, the upper end tops of the lifting piston rods are slopes with high outer parts and low inner parts, the two piston rods are overlapped in tandem, the two overlapped piston rods are connected with each other through a same pull rope, the middle section of the pull rope is lapped and wound in an annular groove at the outer edge of each turning pulley at the longitudinal left upper position and the longitudinal right upper position, the outer edges of the horizontal left slope and the horizontal right slope below the slopes are flat rails on the same level when the lifting piston rods ascend in place, the lower edges of the two rollers are respectively attached to the flat rails on the same level with the outer edges of the horizontal left slope and the horizontal slope, a pressing wheel smaller than the roller is sleeved on the same flat shaft of the roller and is opposite.

The same flat shaft as the roller is sleeved with a balance weight.

The invention has the beneficial effects that: the weight of the roller can reach more than 0.99 at most in the rolling movement, and the roller falls on at least two slopes and the piston rod to promote the lifting of the roller, and the power required for pulling the roller to roll back along the flat track is very small, so that the energy-saving effect is very ideal, the number of the slopes, the piston rods, the pistons and the cylinder sleeves can be increased according to the needs, and the roller has the advantages of simple structure, durability and the like.

Detailed Description

This is further explained below with reference to the drawings.

Referring to fig. 1 and 2, a driving wheel 21 for receiving power is sleeved in the middle of a same flat shaft 3 supported and positioned by bearing seats 20 respectively provided with bearings on the left and right in the transverse direction, two rotating discs 2 are respectively provided with a bearing and jacket 1 on the side edge, two bearing and jackets on the two rotating discs 2 are respectively positioned on the same side edge and are not at the center, a connecting rod 4 is selected to respectively lead the flat shaft 3 and two bearings on the same shaft with the center of a roller 5 to be sleeved and sleeved, two lifting piston rods 10 are vertically arranged, a piston 15 is sleeved and arranged in a cylinder sleeve 14 at the lower end of each lifting piston rod, the upper ends of the lifting piston rods are a slope 7 and a slope 8 which are high outside and low inside, the two piston rods are overlapped in a front-back manner, the two piston rods which are overlapped are mutually connected by a same pull rope 13, the upper middle section of the pull rope 13 is overlapped in an annular groove at the outer edge of a direction-changing pulley 12 which, when the lifting piston rod is lifted to a proper position, the outer edges of the left and right slopes of the lower edge of the slope are flat tracks 9 on the same level, a driving wheel 21 driven by power (not shown in the figure) and two rotating discs 2 rotate, the two rotating discs 2 drive the lower edges of left and right rollers 5 (only one roller is shown in figure 1) to respectively stick to the flat tracks 9 on the same level as the outer edges of the left and right slopes and to roll back and forth along the flat tracks, a pressing wheel 6 smaller than the rollers is sleeved on the same flat shaft as the rollers 5 and is opposite to the slope, balance weights 22 are sleeved on the two ends of the same flat shaft as the rollers for increasing the pressure, and the upper and lower sides of the lifting piston rod 10 are clamped by the leaning wheels 11 to prevent deviation in lifting without change.

The working process and working principle are as follows: the two rollers 5 driven by power press the front lifting slope 8 (divided into front and back in the rolling direction) by the pressure roller 6 in the back and forth rolling movement, because the same pull rope 13 pulls the lifting piston rods 10 at the lower sides of the two slopes, the two slopes fall one by one at the same time and rise one by one, the front falling forms resistance to the rollers, the back rising forms thrust, namely power, to the rollers, the resistance and the thrust are equal to each other and are mutually offset and changed from zero to zero, the slope rising and falling belt is connected with the lower side and synchronously rises and falls with the piston rods connected into a whole, the switch 16 at the lower part of the cylinder sleeve 14 rising to form suction is sucked by the suction to suck water from the water inlet 18 into the cylinder sleeve through the channel 17, the switch at the lower part of the cylinder sleeve falling to form pressure is closed to discharge the water out of the cylinder sleeve, and the switch at the lower part of the cylinder.
