Magnetic double level gauge has some disadvantages and place to be modified, main as follows: the magnetic turning plate liquid being mounted on higher container
Position is difficult in respect of certain observation；Magnetic double level gauge is made because magnetic floating ball or magnetic sheet indicator are there are certain or higher failure rate
It is poor at reliability.
To solve the above-mentioned problems, the invention proposes a kind of liquid level detection devices 100.
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
As shown in Figure 1, the liquid level detection device 100 substantially may include: the first level sensing part 10, the second level sensing
Part 20 and connector.
First level sensing part 10 includes the first main body 11 and can first float 12 of the floating ground in the first main body 11.
Second level sensing part 20 includes the second main body 21 and relocatable the second float 22 being set in the second main body 21.The connection
Part is connected with the first float 12 and the second float 22 respectively, and the first float 12 and the linkage of the second float 22.
Specifically, being respectively provided with the first float 12 and second that can be floated up and down in the first main body 11 and the second main body 21
Float 22, wherein the first float 12 and 22 positional relationship of the second float influence each other, and the first float 12 and the second float 22 are right
Answering the reading at position is liquid level.
Wherein it is possible to by a form for being arranged to follow liquid surface lifting in the first float 12 and the second float 22, and
By another form for being arranged to follow one movement in the first float 12 and the second float 22.For example, by
One float 12 is set as following liquid level to float (for example, the first float 12 is located at liquid level to flat position), and passing through connector will
First float 12 and the connection of the second float 22, so that the second float 22 follows during the first float 12 floats with liquid level
First float 22 floats.
In addition, aforementioned first float 12 refers to the linkage of the second float 22, and when the first float 12 is mobile, the second float 22
It is mobile simultaneously, it, can be by the when the first float 12 moves up by taking the first float 12 is actively mobile (following liquid level) as an example
Two floats are set as moving down, moving down, move horizontally etc., and 22 moving displacement of the first float 12 and the second float
Also and non-required completely the same, it is only necessary to which that the first float 12 and the second float 22 can show the same liquid level.
Liquid level detection device 100 according to an embodiment of the present invention as a result, by the way that the first level sensing part 10 and second is arranged
Level sensing part 20, and pass through the connector for the first float in the first level sensing part 10 and the second level sensing part 20
12 and second are connected between float 22, the height of liquid level can be read by different level sensing parts, especially in liquid
When position is higher, a level sensing part setting can be followed into liquid level, and the setting of another level sensing part is relatively low, thus
Higher level value can be intuitively read in lower position, solve the problems, such as that container is more high-leveled and difficult with visual reading.
For example, it is arranged to the second float 22 when the first float 12 moves up to move down.When liquid level is higher, the
The position of one float 12 is relatively high, and simultaneously, and the position of the second float 22 compares lower, and when reading can choose reading float
Lower second level sensing part 20.In this way, no matter liquid level be it is high or low, user can intuitively read in lower position
Higher level value out solves the problems, such as to be difficult to read when container is higher.
In addition, as apparent from the foregoing descriptions, connector can be arranged to different forms, to realize in liquid
When face is raised and lowered, the first float 12 is identical or opposite with the moving direction of the second float 22.
For example, in some embodiments of the invention, as shown in Figure 1, the connector includes fixed pulley and drawstring 31, drawing
One end of rope 31 is connected with the first float 12, and the other end of drawstring 31 crosses fixed pulley and the second float from the upper surface of fixed pulley
22 are connected.
Two floats are connected by fixed pulley and drawstring 31, the resistance of fixed pulley is smaller or even ignores, Ke Yimin
The floating situation of the first float 12 or the second float 22 is experienced in sense, and reaches the first float 12 and the second float 22 rapidly
To force balance state, the reading for indicating float is accurate.Certainly, above-described embodiment is only illustrative, and can not be interpreted as
Limiting the scope of the invention, for example, the connector can be smooth hole and drawstring 31, one end of drawstring 31 and first
Float 12 is connected, and the other end of drawstring 31 passes through smooth hole and is connected with the second float 22；The connector may be smooth circle
Column and drawstring 31, one end of drawstring 31 are connected with the first float 12, and the other end of stretching crosses smooth cylindrical and the second float 22
It is connected.
Specifically, the linkage of two floats can be realized by drawstring 31 due to being provided with drawstring 31, specifically,
When using a fixed pulley and a drawstring 31, drawstring 31 is hung on fixed pulley and both ends are separately connected the first float 12 and the
Two floats 22, when the first float 12 moves up, the second float 22 will be moved down；When the first float 12 moves down, in drawstring 31
Drive under, the second float 22 will will be shifted up.
In addition, drawstring 31 of the invention, which can also be arranged to one end, applies upward pulling force to the first float 12, and the other end
Apply the pulling force in the directions such as upward, downward, horizontal, inclination to the second float 22；Drawstring 31 can also be arranged to one end to first
Float 22 applies downward pulling force, and the other end applies the pulling force in the directions such as upward, downward, horizontal, inclination to the second float 22.It is logical
Crossing the one or more fixed pulleys of setting can be adjusted, in addition, also needing to be arranged elastic component auxiliary, example in some cases
Such as, because the second float 12 is downward under the effect of gravity, if being arranged to the side that drawstring 31 pulls downward on the second float 22
Case, it is necessary to a upward reset force is provided to the second float 22, to realize the stress balance of the second float 22.Namely
It says, follows liquid level in the first float 12, and when the second float 22 is mobile in company with the first float, if being arranged to drawstring 31 to second
Float 22 applies downward pulling force, at this point it is possible to which elastic string etc., which is arranged, pulls up the second float 22, to realize the second float 22
Stress balance.
In addition, in another specific example of the invention, the connector includes drawstring 31, and the first float 12 is higher than the
Two floats 22, and the upper end of drawstring 31 is connected with the first float 12.At this point it is possible to which only setting drawstring 31 can realize first
The linkage of float 21 and the second float 22, moreover, the first float 12 and the second float can be formed when only with drawstring 31
22 companion movement in the same direction, for example, the second float 22 is under the action of drawstring with ibid when the first float 12 moves up
It moves.Certainly, other auxiliary elements originally can also be set to assist the linkage of the first float 12 and the second float 22, such as be arranged
Fixed pulley above-mentioned.Specifically, as shown in Figure 1, the lower end of drawstring 31 is connected with the second float 22.In this way, when liquid level is very high,
It can be in relatively low position readings, convenient reading.
Optionally, the first float 12 is lower than the second float 22, and the lower end of drawstring 31 is connected with the first float 12, drawstring 31
Upper end be connected with the second float 22.Alternatively, the first float 12 and the second float 22 are contour, and one end of drawstring 31 is floated with first
Son 12 is connected, and the other end of drawstring 31 is connected with the second float 22.
