As shown in Figure 1, the water-level gauge that the utility model provides, this water-level gauge comprises detecting device 2, the first detection rope 31 and cursory 33, detecting device 2 is arranged on the outside of the container 1 that holds the water body that water-level gauge will detect, cursory 33 are positioned at the inside of container 1, and first one end of detecting rope 31 is connected with detecting device 2, and the other end connects cursory 33, cursory 33 act on detecting device 2 by the first detection rope 31, are subject to buoyancy or are not subject to the state of buoyancy so that detecting device 2 detects cursory 33.
Detecting device 2 is arranged on the outside of container 1, and therefore the not water body of contacting container 1 inside can not be subject to the corrosion from water body.Detecting device 2 is directly exposed in air, not oxidized in order to ensure himself, conventionally can add anti-oxidation material at the outside surface of detecting device 2.For example smearing can oxidation resistant coating, or installs protective cover etc. additional in outside.Cursory 33 are positioned over the inside of container 1, and are connected with detecting device 2 by the first detection rope 31, in the time that cursory 33 are not subject to water body buoyancy, rely on cursory 33 self gravitation to pull the first detection rope 31, make 31 pairs of detecting devices 2 of the first detection rope produce acting force; When cursory 33 be subject to buoyancy and upwards float after, first detects rope 31 is no longer subject to cursory 33 downward pulling force, thereby detecting device 2 is not produced to acting force, this two states can show by detecting device 2 respectively, thereby realizes the observation to container 1 water level inside.
Due to cursory 33 and first testing results that detect the oxidized or not oxidized states in rope 31 surface and can not have influence on detecting device 2, and cursory 33 and first detect rope 31 changes conveniently, cost is low, after damage, can directly from container 1, take out and change, can not have influence on the testing result of detecting device 2, greatly increased the serviceable life of water-level gauge, also avoided the great number cost bringing owing to changing accessory simultaneously.
Particularly, the kind of detecting device 2 can have multiple, as shown in Figure 2, in an embodiment of the present utility model, list: detecting device 2 comprises bracing frame 21, pivot arm 22 and counterweight 23, bracing frame 21 is positioned at the top of container 1, pivot arm 22 is by pivot and bracing frame 21 pivot joints, and one end of pivot arm 22 is fixed with counterweight 23, and the other end and first detects rope 31 and is connected.
Bracing frame 21 is taking pivot as rotation center, one end connects first and detects rope 31, other end fixed weight 23, in the time that the first detection rope 31 is subject to the pulling of cursory 33 gravity, first detects rope 31 pulls one end of pivot arm 22 and by pivot, counterweight 23 is upward deflected, and makes pivot arm 22 in the first state; In the time that cursory 33 are subject to buoyancy and upwards float, pivot arm 22 is no longer subject to the pulling force of the first detection rope 31, makes pivot arm 22 rotate backward and upwards lift to connect first one end of detecting rope 31 under the effect of counterweight 23, makes pivot arm 22 in the second state.The two states showing by pivot arm 22, can observe the water level of container 1 inner water body, thus the testing goal of realization.
Further, as shown in Figure 2, in order to realize the automatic detection of water-level gauge, on detecting device 2, inductive switch 24 can also be set, inductive switch 24 is arranged on a side of pivot arm 22, to detect the position of pivot arm 22.At pivot arm 22 during in different conditions, inductive switch 24 can detect the residing diverse location of pivot arm 22, and induced signal is delivered in external unit, by receiving to such an extent that different induced signals can show the SEA LEVEL VARIATION of learning in container 1 in external unit.
