Description
Technical field
The present invention relates to a kind of hydraulic cylinders, and in particular to a kind of support knot of solar battery sheet suitable for low temp area
Structure.
Background technology
Solar energy refers to the infrared radiant energy of the sun, is a kind of renewable resource, have measure it is big, harmless, generally etc. many excellent
Point.The history of human use's solar energy can trace back to ancient times people using sunshine article, making food etc..And now people
Demand to solar energy has no longer been merely to utilize the thermal energy of the sun.1615, French engineer's Cox invented the world
The engine of upper First Driven by Solar Energy opens the utilization history of modern age solar energy.
Solar panel refers to turning solar radiant energy by the way that photoelectric effect or photochemical effect are direct or indirect
Change the device of electric energy into.Solar panel is primarily now applied to traffic, communication, oil drilling platform, street lamp, photovoltaic electric
The numerous areas such as stand, other than above-mentioned field, solar panel be also used in remote segment areas without electricity such as plateau,
The place such as pastoral area or frontier sentry is the household electricity that the army and the people provide.
When applied to outlying areas without electricity, due to the impermanence of some areas Changes in weather, it is susceptible to hail, in order to avoid
Hail causes to damage to solar cell plate surface, the executive component that people pass through hydraulic system --- and hydraulic cylinder controls solar energy
The deflection direction of solar panel falls the incidence angle on solar panel to change hail, mitigates hail to solar cell
The collision dynamics of plate.But in the case where ambient air temperature is low, hydraulic oil viscosity increases, or even the solidification of section hydraulic oil occurs
The phenomenon that, cause hydraulic cylinder charge oil pressure to reduce, the power consumption of hydraulic oil pump, which has to be larger than nominal situation several times, could maintain hydraulic pressure
Normal direction of rotation of the cylinder to solar panel, this is very big to the loss of hydraulic oil pump.
Invention content
The technical problem to be solved by the present invention is to the defect for conventional cylinder, and it is an object of the present invention to provide one kind is suitable for
The support construction of the solar battery sheet of low temp area, solve conventional cylinder maintain normal fuel injection in low temperature environment and
Caused by the big problem of power consumption.
The present invention is achieved through the following technical solutions：A kind of support knot of solar battery sheet suitable for low temp area
Structure, including the cylinder barrel of one end open and with the bolted cylinder cap in open end, the cylinder barrel side be provided with the first oil pipe and
Second oil pipe is provided with piston, guide sleeve in cylinder barrel, is fixed with piston rod in the piston, and the piston rod is towards cylinder cap
One end activity through guide sleeve, cylinder cap and be bolted export head, first oil pipe, the second oil pipe internal diameter along position
Gradually increase in one end on cylinder barrel to the other end, the piston both ends are both provided with annular piston pad, the annular piston pad
Outer diameter be equal to the internal diameter of cylinder barrel, the internal diameter of the annular piston pad gradually increases along the both ends of piston to cylinder barrel, the guiding
It is fluted to cover surface setting, several balls are provided in the groove, the ball is contacted with piston rod, groove.
In part cold district, low temperature causes the hydraulic oil viscosity in hydraulic oil pump to increase, and adding can in hydraulic oil
Can there can be water so that even can form solid in hydraulic oil, above-mentioned two situations all reduce the mobility of hydraulic oil so that
Hydraulic pressure oil flow rate is slow.When the pressure that hydraulic oil pump is exported under normal operating mode makes hydraulic oil to piston effect, hydraulic pressure
Oily slug flow speed, weak force are not enough to push piston proper motion, so that the output end operation irregularity of hydraulic cylinder.
To solve the above-mentioned problems, double acting list of the hydraulic oil to piston effect power can be increased the present invention provides a kind of
Hydraulic piston rod cylinder.
The present apparatus has cylinder barrel, the first oil pipe, the second oil pipe, piston, piston rod, guide sleeve, cylinder cap and export head, these
Device is all that traditional two-action single-rod hydraulic cylinder has.Unlike traditional hydraulic cylinder, the present apparatus is in work
The both ends of plug are both provided with annular piston pad.The shape of annular piston pad is a cylinder for offering through-hole, and piston rod is slided
It is dynamic that by the through-hole, the outer diameter of cylinder is equal to the internal diameter of cylinder barrel, and the diameter of the internal diameter of cylinder, i.e. through-hole is variation,
Along from the one end being fixed on piston, to one end far from piston, the diameter of through-hole is gradually increased.Preferably, through-hole position
Diameter in that end on piston is equal to the diameter of piston rod, and the diameter of one end far from piston is equal to the internal diameter of cylinder barrel.It is above-mentioned
Through-hole diameter gradually to increase at least include two kinds of situations, the first situation is that through-hole is cone, from being parallel in cylinder barrel
It is seen on the section of axis, through-hole is isosceles trapezoid；In the second situation, from the section for being parallel to cylinder barrel central axes, through-hole
For hemisphere.
When hydraulic oil is close to piston, along piston to the direction at cylinder barrel both ends, hydraulic oil is divided into several sections.Wherein first
Section and piston contact push piston motion, and second segment is by the promotion of third section to push first segment, and first segment is by piston
Reaction force while also to second segment transmit a reaction force.Traditional hydraulic cylinder, only the piston with cylinder, round
The piston both ends of cylinder and the contact surface of hydraulic oil are plane.When first segment hydraulic oil acts perpendicularly to piston, it is subject to
Reaction force is vertically second segment hydraulic oil, correspondingly, second segment hydraulic oil vertically reacts on third section hydraulic oil,
And so on.Allow in this way third section hydraulic oil need provide bigger power can just overcome second segment hydraulic oil to reaction
Power.It can be obtained by foregoing description, for the piston that contact surface is plane, hydraulic oil pump is needed when providing output pressure
So that the reaction force that hydraulic oil overcomes piston vertical can push piston to be moved in cylinder barrel.Improved hydraulic cylinder is then in work
Annular piston pad is increased beyond the Great Wall, when first segment hydraulic oil acts perpendicularly on the side wall of the through-hole of annular piston pad, annular
Piston pad is no longer perpendicular to first segment hydraulic oil to the reaction force of first segment hydraulic oil, and is perpendicular to the method for side wall curved surface
Line, and this power edge is parallel to the axial component of cylinder barrel certainly less than resultant force, institute perpendicular to the direction of first segment hydraulic oil
The reaction force that piston sends first segment hydraulic oil to is significantly reduced with annular piston pad so that hydraulic oil pump is same
When output pressure, the reaction force that piston is given reduces, and piston is easier to move in cylinder barrel；Moreover, when annular piston pad
It acts on and is parallel to the component of cylinder barrel radial direction to longitudinal component of the reaction force of first segment hydraulic oil and makes first segment hydraulic oil
Squeezed to the central axes of through-hole, the effect generated in this way is, along annular piston pad through-hole wall surface to through-hole central axes direction,
Hydraulic oil acts on the power on annular piston pad and gradually increases from edge to intermediate, since contact area is gradually reduced, central axes
The hydraulic oil at place also increases the pressure of annular piston pad therewith so that movement of the piston in cylinder barrel is more prone to.
In conclusion by annular piston pad, reaction force direction of the piston to hydraulic oil is changed, to reduce liquid
Pressure oil pump output terminal needs the reaction force from piston overcome so that movement of the piston in cylinder barrel is more smooth, effectively
Ground reduces the output power consumption of hydraulic oil pump.In low temperature environment, even if there is the phenomenon that flow velocity is slow, partially solidified and leads in hydraulic oil
It causes the active force for acting on piston small, hydraulic oil pump can also allow that not increase excessive power consumption, providing stronger output pressure
Under the premise of so that the present apparatus is worked normally.
It is being slidably connected for face and face, the metal covering and guiding of piston rod between the piston rod and guide sleeve of conventional cylinder
It is in contact between the metal covering of cylinder.But ambient air temperature it is low when, the oxidation film of metal surface is harder, the friction between metal covering
Bigger when coefficient is compared with room temperature, this adds increased the degree of difficulty to rub between metal covering, in order to avoid such case, some
Hydraulic cylinder is coated with lubricating oil between piston rod and guide sleeve, but, low temperature can equally cause lubricating oil viscosity increase or
Parts of lubricating oil solidifies, and causes the relative movement between piston rod and guide sleeve difficult, even piston rod can be caused not when serious
It can normally be slided in guide sleeve.The piston rod that above-mentioned two situations generate slides the problem of being obstructed in guide sleeve, if it is desired to
It to keep piston rod to work normally in low temperature environment, then hydraulic oil pump just needs to increase output pressure, improve hydraulic oil pump
Power consumption.To solve the above-mentioned problems, the present apparatus is fluted in the setting of the surface of guide sleeve, and several balls are provided in groove,
These balls are all contacted with piston rod and groove, that is to say, that the thickness of groove is less than the diameter of ball.By above-mentioned setting,
Friction between piston rod and groove between face and face has been transformed into the rolling friction between ball and piston rod, groove, rubs
It wipes power to substantially reduce so that piston rod can be moved more easily in cylinder barrel, reduce the power consumption of hydraulic oil pump.
The internal diameter of first oil pipe and the second oil pipe is all changed to from far from cylinder barrel one end to one end on cylinder barrel by
Gradual change is big, the first oil pipe and the second oil pipe being equal instead of internal diameter everywhere in conventional cylinder.There are two excellent for setting in this way
Point.First advantage is, when in low temperature environment, since hydraulic oil viscosity is big, flowing is slow, to keep the normal work of export head
Work, piston rod normally move up and down, and hydraulic oil pump needs to pay extra power consumption.Traditional hydraulic cylinder is using internal diameter everywhere
The first and second equal oil pipes, flow velocity is almost equal everywhere for hydraulic oil in oil pipe, still, by improved first oil pipe
With the second oil pipe, internal diameter is tapered into from hydraulic oil pump to internal diameter of cylinder, when oil inlet, since pressure is constant, and oil pipe
Cross-sectional area is gradually reduced, so the pressure that hydraulic oil is subject to increases, speed increases, relatively traditional hydraulic cylinder oil inlet pipe, liquid
Pressure oil enters the speed of hydraulic cylinder faster, to impulse force bigger caused by existing hydraulic oil in cylinder barrel, can preferably push
Piston simultaneously drives piston rod to move.Second advantage is, when the present apparatus is held upright, plays a part of lifting by output device
When, the hydraulic oil below piston has been subject to the pressure more transmitted by piston, this partial pressure is essentially from portion
Divide by the gravity of output device, the gravity of the gravity of piston and piston rod.After oil pipe is improved, from cylinder barrel to hydraulic oil pump,
Its internal diameter gradually increases, and after cylinder barrel outflow, volume increases hydraulic oil suddenly, and the speed of hydraulic oil reduces, the hydraulic oil in front
Inhibition is played to the hydraulic oil at rear, reduces the mobility of rear hydraulic oil.The hydraulic oil that slowly flows out is to moving down
Piston, piston rod can play better supporting role, avoid piston rod from falling suddenly and impinge upon on cylinder barrel, cause piston rod and
Cylinder barrel damages, and even the device exported can be damaged when serious.
Further, the first oil pipe, the second oil pipe maximum inner diameter be 2 ~ 3 times of minimum diameter.It is found by putting into practice, when
When maximum inner diameter is 2 ~ 3 times of minimum diameter, both will not because the pipe aperture on cylinder barrel is too small and cause partially due to
The solid particle that low temperature is formed blocks oil pipe, and hydraulic oil discharge cylinder barrel speed per hour can also be avoided to spend slowly, lead to piston rod, piston
It moves down excessively slowly.
Further, groove is annular groove, and the annular groove central axes are overlapped with the central axes of cylinder barrel.Groove is set
It is set to the annular groove that the central axes of central axes and cylinder barrel coincide, more balls can be accommodated, further increase rolling
The area of friction makes movement of the piston rod in cylinder barrel be more prone to.
Further, the central axes of cylinder barrel, piston rod, piston and annular piston pad overlap.Setting can make in this way
Being more uniformly stressed for piston is obtained, while piston rod will not lead to fracture in output there is a situation where making power due to bias.
Further, the cushion pad positioned at cylinder barrel blind end is provided in inner wall of cylinder.Due in installation solar cell
When plate, the open end of cylinder barrel is directed towards top, thus the second oil pipe drawing liquid pressure oil walk and the first oil pipe when into hydraulic oil,
Due to gravity, piston is easier to slide to the blind end of cylinder barrel, is hit so as to cause piston, piston rod or annular piston pad
The blind end of cylinder barrel not only results in blind end and is damaged, while the solar panel backboard that can also cause export head to be connected
It is impaired to result even in the device connected in export head for shake when serious.After cylinder barrel blind end is provided with cushion pad, then it can keep away
Exempt from the above situation, it is preferred that the material of cushion pad uses nitrile rubber, and nitrile rubber has the characteristics that wear-resisting, heat-resisting, and has
Certain deformability, can be to generating bounce.Preferably, the one end of piston rod towards cylinder barrel blind end is through piston
Afterwards, extend one end distance to blind end so that the end face of piston rod is in contact with cushion pad.
Further, it is provided with pin hole in export head.It can be provided with pin hole in export head, sold by being inserted into pin hole
Export head is fixed together by axis with the device lifted is needed.
Compared with prior art, the present invention having the following advantages and advantages：
1, the present invention changes reaction force direction of the piston to hydraulic oil, to reduce liquid by annular piston pad
Pressure oil pump output terminal needs the reaction force from piston overcome so that movement of the piston in cylinder barrel is more smooth, effectively
Ground reduces the output power consumption of hydraulic oil pump；In low temperature environment, even if there is the phenomenon that flow velocity is slow, partially solidified and leads in hydraulic oil
It causes the active force for acting on piston small, hydraulic oil pump can also allow that not increase excessive power consumption, providing stronger output pressure
Under the premise of so that the present apparatus is worked normally；
2, the present invention will make improvement to the first oil pipe and the second oil pipe, and not only in low temperature environment oil inlet, oil pipe is transversal
Area is gradually reduced, and hydraulic pressure speed oil increases, and relatively traditional hydraulic cylinder oil inlet pipe, hydraulic oil enters the speed of hydraulic cylinder more
Soon, to impulse force bigger caused by existing hydraulic oil in cylinder barrel, it can preferably push piston and piston rod is driven to move；Together
When, when the present apparatus is held upright, and plays a part of lifting by output device, for hydraulic oil after cylinder barrel outflow, volume is unexpected
Increase, the speed of hydraulic oil reduces, and the hydraulic oil in front plays inhibition to the hydraulic oil at rear, reduces rear hydraulic oil
Mobility, the hydraulic oil slowly flowed out can play better supporting role to the piston, the piston rod that move down, avoid piston rod
It falls and is impinged upon on cylinder barrel suddenly, piston rod and cylinder barrel is caused to damage；
3, the present invention guide sleeve surface setting it is fluted, several balls are provided in groove, these balls all with work
Stopper rod and groove contact, the friction between piston rod and groove between face and face are transformed between ball and piston rod, groove
