Description
Technical field
The present invention relates to water pump water supply system control technology fields, more particularly, to a kind of for the floating of water pump water supply system
Ball switch.
Background technique
The water drain that existing water pump water supply system generally includes a reservoir, is connected to the outlet pipeline of reservoir
Pump, the use water installations connecting with outlet pipeline are equipped with corresponding level control switch for water in reservoir.In the water system,
When the water level of reservoir gradually rises to the upper limit water level of setting, level control switch for water exports an electric signal, to control
Draining water pump starts to work and is supplied water to external with water installations.When the water level of reservoir gradually decreases to the lower limit water level of setting
When, level control switch for water exports an electric signal, so that the draining water pump for controlling connection water outlet stops working, avoids reservoir
Water level continues to decline.And the water supply of reservoir can then be provided by municipal water supply pipeline or other water supply pipes provided for oneself, example
Such as, we can be with one water inlet water pump of setting on the inlet pipeline of reservoir connection, and water pump of intaking can extract such as rainwater collection
It supplies water to reservoir at the water sources such as collecting system, underground water.Level control switch for water is also controllable while control drains water pump at this time
The movement of water inlet water pump, so that the water level of reservoir be made to maintain upper limit water level and lower limit water level time always.When reservoir with
When municipal water supply pipeline is connected, then for corresponding control device need to be arranged on water supply pipe, in order to level control switch for water
The electric signal of output can control the control device on water supply pipe, and then the on-off of controllable municipal water supply pipeline simultaneously.
Existing level control switch for water generallys use float switch comprising a floating ball that can be gone up and down in reservoir,
Inside has the control shell of control circuit and conducting switch, and when the water level of reservoir rises, floating ball is under the action of welfare
Follow rising.When floating ball contacts control shell, the intracorporal conducting switch conduction of control hole can be made, to export one outward
Electric signal；When the water level decreasing of reservoir, floating ball follows decline and mutually separates with control shell, and conducting switch at this time is disconnected
It opens, control circuit exports an electric signal outward again." a kind of vertical floating ball is opened for example, disclosed in Chinese patent literature
Close ", 102163517 A of publication No. CN, including closed hollow housing is provided with microswitch, the shell in the shell
It is provided with hollow floating ball in vitro, rotating horizontally to control the microswitch folding for Y shape is additionally provided in the shell
Rocker arm, the sunpender of rod moving up and down is additionally provided in the shell, the lower part of the sunpender is stretched out outside the shell,
And the floating ball is connected, two free ends of the rocker arm and the top of the sunpender are provided with magnet.When water level rising makes to float
Ball rises to high liquid level, and floating ball drives sunpender up to move simultaneously.When magnet at the top of sunpender is passed through among two magnet of rocker arm,
Occur magnetic fields, two magnet on rocker arm, an offers repulsive force, another provides the suction-combining force, therefore the magnet of sunpender and
The one of magnet of rocker arm is attracted.Rocker arm pivots press the Action Button of microswitch to microswitch side, and switch is led
It is logical, start pumping drainage.When water level decreasing makes floating ball drop to low liquid level, since the self gravity of floating ball overcomes the suction of magnet
Gravitation, therefore sunpender has been driven to move down, the magnet being previously attracted is separated, and rocker arm pivots are micro- to no microswitch side
Dynamic switch disconnects, and water pump stops working.
However there are following defects for above-mentioned float switch：Since sunpender is when rising to high liquid level, the magnet of sunpender upper end
The magnetic force being horizontally oriented formed between two magnet of the rocker arm for the Y shape that can be horizontally rotated（One is suction, another
It is repulsive force）, the magnetic force of the level can not limit the axial movement of sunpender.That is, sunpender at this time still can be light
It changes places and moves up and down.Therefore, when the slightly larger fluctuation of amplitude occurs in the water level of the reservoir in high water level, floating ball can follow storage
The liquid level in pond fluctuates up and down, and correspondingly, sunpender will drive the magnet fluctuation up and down together of upper end, to make rocker arm in water level wave
Electric signal is continually exported when dynamic, and then water pump is made continually to start or stop work, influences the stability of water system work.
Summary of the invention
The purpose of the present invention is to solve be easy to make because of the fluctuation of reservoir game present in existing float switch
The problem of at water pump frequent movement, provides a kind of float switch for water pump water supply system, can be effectively prevented from because of reservoir
Caused by the fluctuation of liquid level the problem of water pump frequent movement, be conducive to the stability and reliability that improve water level control.
To achieve the goals above, the present invention uses following technical scheme：
A kind of float switch for water pump water supply system, including the floating ball with sealing cavity and the control shell with line outlet
Body, the floating ball center are perforated equipped with connecting rod, and the downside of the control shell is equipped with connecting rod, and the connecting rod is pierced by floating ball
The lower end of connecting rod perforation is equipped with limited block, and the downside of the control shell is equipped with the lifting groove of upward indent, thus controlling
A lifting protrusion is formed in shell, and the sliding shoe being slidably connected in lifting groove is equipped in the upper end of connecting rod, is being slided
The left and right ends of block are respectively equipped with lower magnet, and the raised top position of lifting is located in the control shell and is equipped with lateral compression bar,
It is rotatably connected in the middle part of the compression bar on control shell, the left and right ends of compression bar are respectively equipped with magnet, and the sliding shoe is left
The lower magnet at end is identical with the polarity of the upper magnet opposite side of compression bar left end, and the lower magnet and compression bar of the sliding shoe right end are right
The polarity of the upper magnet opposite side at end is on the contrary, be equipped with the position sensor that can sense compression bar state, institute in the control shell
The output end for stating position sensor is connected with the connecting wire for being hermetically pierced by the line outlet outward.
The present invention one middle part of setting in control shell is rotatably connected on the compression bar on control shell, to make compression bar can
It swings and is in seesaw shape.In this way, floating ball follows rising when the water level of reservoir rises.When floating ball contacts connecting rod
When the sliding shoe of upper end, connecting rod and sliding shoe can be driven to rise, the lower magnet of sliding shoe left end is close to a compression bar left side at this time
The upper magnet at end, so that the left end to compression bar forms a repulsive force；The lower magnet of sliding shoe right end is close to the upper of compression bar right end
Magnet, so that the right end to compression bar forms a suction.The right end of compression bar pushes and lifts on left end and form positive pendulum at this time
It moves, then trigger position sensor, and an electric signal is exported by connecting wire outward, for controlling the control of pump working
Device can be such that water pump starts upon receipt of the signal.When the water level decreasing of reservoir, floating ball follows decline and leaves sliding
Block, connecting rod move down therewith, and compression bar at this time restores to the original state, so that position sensor is made to export an electric signal again, after
And water pump is made to stop working.Since compression bar of the invention is lateral arrangement, the magnetic force between lower magnet and upper magnet is
Vertical direction.That is, compression bar is to the axis that the magnetic force of connecting rod is along connecting rod when connecting rod is in upper limit position
To.Therefore, we can be by the magnetic force size between magnet under reasonable design and upper magnet, so that compression bar is to connecting rod
Total magnetic force is slightly larger than the weight of connecting rod.In this way when the water level of reservoir has fluctuation and moves down floating ball moment, the magnetic of compression bar
Power can make sliding shoe and connecting rod remain within upper limit position.Only when the water level of reservoir very drops to lower limit water level
When, the gravity of floating ball so that sliding shoe and connecting rod be made to move down, thus can be effectively prevented from because of water storage in connecting rod
Caused by the fluctuation of pit level the problem of water pump frequent movement, be conducive to the stability and reliability that improve water level control.It can be with
Understand, when sliding shoe and connecting rod be in upper limit position, the lower magnet of left end and the upper magnet generation repulsive force of left end,
And therefore magnet and magnet formation attraction on right end under right end are lifted and right end pushing on compression bar left end at this time.Namely
It says, the lower magnet of left end is larger at a distance from magnet on left end, and the upper magnet of the lower magnet of right end and right end is closer,
And then it is advantageously ensured that the attraction between the right end and sliding shoe right end of compression bar is greater than the left end of compression bar and a left side for sliding shoe
Repulsive force between end, and then connecting rod can be made to be adsorbed on by sliding shoe by compression bar in the lifting groove of control shell.

There are a first position and a second position, when lever compression is displaced downwardly to the second position, the second movable contact and the second stationary contact
Point contact；When lever Self-resetting to first position, the first movable contact and the first stationary contact point contact.
In this way, float switch of the invention is applicable to the water system with two water pumps, wherein First water pump is used
It draws water in water source, to supply water to reservoir, second water pump is used for the draining of reservoir, to supply to water installations
Water.When lever is naturally in first position, the first movable contact and the first stationary contact point contact, thus one electric signal of output,
It is supplied water using controlling First pumping for water pump as reservoir, second fetus water pump is in shutdown status at this time；When on the water level of reservoir
When rising to setting height, floating ball by water buoyancy and rise to upper limit position, floating ball contacts the sliding shoe of connecting rod upper end, from
And sliding shoe and connecting rod is driven to rise, the lower magnet of sliding shoe left end forms a repulsive force to the left end of compression bar at this time；
The lower magnet of sliding shoe right end forms a suction to the right end of compression bar, so that the right end of compression bar is pushed and is lifted on left end, then squeezes
The lever of travel switch is pressed, lever compression is displaced downwardly to the second position, the second movable contact and the second stationary contact point contact, so that output is another
One electric signal is drained outward with controlling second pump working, so as to being supplied water with water installations, First water pump stops at this time
Machine.When the water level of reservoir declines again, floating ball declines, and lever at this time, which moves up, is reset to first position, and second water pump stops
Only drain, and First water pump is then restarted and is supplied water for reservoir.
In order to avoid the fluctuation of water level in reservoir causes the improper lifting of floating ball, and then keep position sensor output wrong
Electric signal accidentally.As shown in figure 5, spiral raised line 44 is arranged creatively on the periphery of connecting rod by the present invention, correspondingly, float
Ball is in regular hexagonal prism shape, and the spiral groove being adapted to spiral raised line is arranged in the connecting rod perforation inner sidewall of floating ball, to make floating ball spiral shell
Line is connected in connecting rod, and the lead angle of spiral raised line is between 60 degree to 75 degree.In this way, when reservoir is due to wind
Or other reasons cause water level have quickly up and down fluctuation when, floating ball can form spiral lift in connecting rod.That is,
There are one rotations while moving up and down for floating ball, at this point, the floating ball of regular hexagonal prism shape both will receive the one of water in rotation
A resistance, and will receive the frictional resistance of spiral raised line, to limit the lifting speed of floating ball, and then make floating ball production in lifting
The effect of a raw lag.When water level rapid decrease, floating ball follows slow decline, and the descending stroke of floating ball is less than water level at this time
Descending stroke；When water level starts rapid increase, the floating ball slowly declined stops declining and starting under the buoyancy of water
Slowly rise.It is understood that the lifting frequency of the floating ball slowly gone up and down, lifting travel can be lower than the liter of water level far away
Frequency reducing rate and lifting travel.Because the lifting travel of floating ball is less than the length of connecting rod at this time, that is to say, that if elevating lever position
In upper limit position, since the limited block of connecting rod lower end will not be touched when floating ball decline, connecting rod is in upper and lower magnet
Upper limit position is continually maintained under magneticaction；If connecting rod is in lower position, the minimum stroke range of floating ball it is upper
Lower shaking not will drive connecting rod and move up to upper limit position, so that connecting rod is made to be continuously maintained in lower position, thus can be effective
Ground avoids the electric signal that fluctuates continually output error of the position sensor because of water level, guarantees the normal work of water pump.Work as water storage
When normally rising or falling occurs in the water level in pond, floating ball can just rise or fall enough stroke, to drive connection
Bar lifting, to make position sensor export corresponding electric signal.
Finally, we can connect a stamping forming fixed bracket 27 in the downside screw of control shell, thus side
Just the installation and fixation in reservoir.
