Background

The existing water gauge is mainly fixedly installed at one time, and the zero point of the water gauge is only required to be calibrated after flood prevention under general conditions. Because the water environment is complex, many water gauges are often attached and shielded by other objects after being installed, so that the normal observation of the water gauges is affected, and particularly, the situation that the surfaces of the water gauges are attached by marine organisms often occurs when a tide level station is set up at the sea. Therefore, the water gauge set up at sea often needs to be cleaned regularly, and some places also need to be re-set due to the special installation position. The hydrologic observation has higher requirement on the zero precision of the water gauge, and the zero is necessarily changed when the water gauge is cleaned and reset, so that the water gauge zero is required to be re-calibrated by a technician with manpower and material resources, and great inconvenience is brought to the hydrologic observation work.

Compared with the prior art, the utility model has the advantages that:

1. is convenient for cleaning the water gauge. The traditional water gauge is installed in a fixed mode, 2-3 persons are needed for cleaning and reloading each time, the water gauge is a detachable water gauge, cleaning and reloading can be completed by only 1 person, and meanwhile time and labor are saved;

2. the water gauge zero point with higher accuracy after reinstallation is convenient to obtain. After traditional reloading water gauge, need rearranging technician uses high accuracy surveying instrument to carry out the school to the water gauge zero point and survey, need spend certain manpower and materials, this water gauge only needs alone to dismantle behind the clearance water gauge, directly read main scale, obtain fractional part through reading main scale and base scale difference, and then obtain accurate water gauge zero point, whole water gauge clearance and zero point school survey work, all can alone accomplish, it is more efficient, labour saving and time saving, once installation can clear up repeatedly used many times simultaneously, the cost of water gauge maintenance has also been greatly reduced.

When in use, the base 1, the main scale 2 and the observation water scale 7 are made of stainless steel, so as to resist rust and corrosion and deal with complex water environment.

An observation water gauge 7 with a scale of 0.01 meter is fixed on the main gauge 2, and the length of the observation water gauge 7 can be determined according to the on-site installation condition; simultaneously main scale 2 and base 1 are equipped with main scale auxiliary scale 9 and base auxiliary scale 10 respectively, and wherein main scale 2 is equipped with 10 little main scale scales 8, and total length 9 millimeters, and each graduation is 0.9 millimeter, and the reading accuracy is 0.1 millimeter. The base 1 is provided with a base scale with a minimum scale of 1 mm.

The main scale 2 both sides are provided with the pulley, and 1 curb plate internal surface of base is provided with recess 4 and the arc wall 5 of being connected rather than, and accessible pulley 3 is comparatively convenient dismouting main scale 2 during the dismouting.

After the reloading is finished, the height difference between the main scale 2 and the base 1 is determined by reading the scales of the base 1 and the main scale 2, and the height of the base 1 can be measured in advance because the base 1 is fixed, so that the zero point height of the main scale 1 is determined through the height difference between the main scale 2 and the base 1.
