In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
~4 are please referred to Fig.1, the utility model provides a kind of liquid level gauge 10 for open-top receptacle, including fixed mechanism
11, movable device 12 and detent mechanism 13.
The present embodiment fixed mechanism 11 is including a fixed link 111 being vertically arranged and along 111 length direction of the fixed link
At least two guide pads 112 set gradually are each both provided with guide groove 112a up and down on the guide pad 112,
In practical application, fixed link 111 is securable on 20 side wall, and guide pad 112 is then located at 20 upsides；Movable device 12 wraps
A floating body 121 and a guide rod 122 are included, 122 lower end of the guide rod is connect with the floating body 121, upper end sequentially passes through at least
Guide groove 112a on two guide pads 112, and the guide rod 122 is connect with guide groove 112a side walls, when floating
When body 121 moves up and down with liquid in open-top receptacle 20, guide rod 122 can be driven to move up and down along guide groove 112a, so as to
Liquid level in detection open-top receptacle 20；For the ease of adapting to the open-top receptacle 20 of different depth, guide rod described in the present embodiment
122 multiple guide part 122a by being detachably connected from beginning to end successively are formed, and are both provided with along it on each guide part 122a
The graduation mark 122b of length direction arrangement, in practical application, guide rod 122 can be arranged according to the internal depth of open-top receptacle 20
Length, and according on graduation mark 122b digital independent detection liquid level depth, such as：When the depth of open-top receptacle 20 is 5m
When, if the effective length of each guide part 122a is set as 1m, 5 or 6 guide part 122a can be arranged and be sequentially connected, in turn
Form the guide rod 122 that a length is more than depth to be measured.For the ease of reading, the graduation mark on two neighboring guide part 122a
Continuity reading can be used in the reading of 122b, for example, when the reading on one of guide part 122a is 0~1m, then its phase
Graduation mark 122b readings on adjacent guide part 122a are 1~2m, and operating personnel when level sensing can be convenient for read.
To the level readings of detection and N Reference Alignment is carried out for the ease of operating personnel, liquid level gauge 10 described in the present embodiment
Further include detent mechanism 13 comprising locating rod 131, positioning pointer 132 and positioning screw 133,131 both ends of the locating rod point
It is not connect with two neighboring guide pad 112,132 one end of the positioning pointer is slidably connected to the locating rod 131, the positioning
133 one end of screw passes through 132 side wall of the positioning pointer and is connected to the locating rod 131；Specifically, locating rod 131 is vertical
It is disposed in proximity between the two neighboring locating piece of downside, positioning pointer 132 is horizontally disposed, and one end sliding sleeve is set to locating rod
131, and the side wall of itself and 131 connecting pin of locating rod is provided with location hole, positioning screw 133 and location hole screw-thread fit, can lead to
Positioning pointer 132 is fixed in locating rod 131 by the tight positioning screw 133 of overwinding；When practical application, on multiple guide part 122a
The reading of graduation mark 122b is in from top to bottom to be incremented by state, in order to improve the accuracy of detection, needs to carry out N Reference Alignment, that is, works as
When floating body 121 touches 20 bottom of open-top receptacle, positioning pointer 132 corresponding graduation mark 122b readings are zero, therefore the present embodiment
When mounted, the position of positioning pointer 132 is adjusted in liquid level gauge 10 so that when floating body 121 contacts 20 bottom of open-top receptacle, positioning
The reading for the graduation mark 122b that pointer 132 is directed toward is zero, is conducive to ensure the accuracy of subsequent operation personnel reading, can avoid
Because error in reading leads to the reduction of level sensing accuracy.It should be noted that said reference considers to float during correcting
Error caused by the gravity of body 121 and guide rod 122, in practical applications, operating personnel can be according to floating bodies 121 and guiding
The position of the gravity secondary calibration positioning pointer 132 of bar 122.
Since the gravity of floating body 121 and guide rod 122 can lead to error, therefore the present embodiment floating body 121 and guide rod 122
It is all made of light material, such as foam or plastic material；And in order to reduce the weight of guide rod 122, guide part 122a can be set
It sets in a tubular form, internal thread, one connector 122c of the axially extending formation in lower end, the connector is arranged in the upper ends each guide part 122a
The upper matched external screw threads of internal thread being arranged with the tops guide part 122a of 122c.
When guide rod 122 moves up and down along guide groove 112a, outer wall and unavoidably generation friction in guide groove 112a
Power easily prevents guide rod 122 from moving up and down along guide groove 112a, therefore in order to improve the precision of detection, consolidate described in the present embodiment
It further includes the multiple pulleys 113 being uniformly arranged on the guide groove 112a inner walls to determine mechanism 11, and the outer rim of each pulley 113 is equal
It is connected to 122 outer wall of the guide rod, when guide rod 122 moves up and down along guide groove 112a to multiple landings are along guide rod
122 outer walls roll, and sliding friction can be converted to fixed friction, and then reduce rubbing between guide rod 122 and guide pad 112
Wipe power.
The present embodiment guide groove 112a can be arranged in arbitrary shape, in order to which guide rod 122 is preferred with respect to its up and down motion,
Such as U-shaped, arbitrary polygon, major arc shape, ellipse or circle, and guide part 122a can be arranged and agree with guide groove 112a phases
Shape may also set up and surround the shape to be formed with the outer rim of multiple pulleys 113 and mutually agree with.Wherein, the present embodiment guide groove 112a
It is arranged rounded.
When guide part 122a is provided in round, it is unavoidably oppositely oriented the rotation of block 112, and for the ease of reading,
Each the graduation mark 122b on the guide part 122a is at least two groups to the present embodiment, and at least two groups graduation mark 122b is along institute
It states guide part 122a to be arranged circumferentially, at least two groups graduation mark 122b can be set, be on the one hand convenient in open-top receptacle 20
Different location accurate reading, on the other hand when guide rod 122 rotate different angle when accurate reading.Meanwhile the present embodiment positions
132 remotely located bar of pointer, 131 one end can be arranged in frame-type, and guide rod 122 is built in the frame of positioning pointer 132, to
It is read convenient for multi-angle.
Specific embodiment of the present utility model described above does not constitute the restriction to scope of protection of the utility model.
The various other corresponding changes and deformation that any technical concept according to the present utility model is made, should be included in this practicality
In novel scope of the claims.
