Description

Technical Field

[0001] The utility model belongs to the technical field of water gauge observation, in particular to a water gauge observation surge offset device. Background Art

[0002] Water gauges are used to observe changes in groundwater levels and ocean tidal levels. They can also be used to monitor water levels in rivers, lakes, reservoirs and other areas. Common types are upright water gauges, inclined water gauges, low-pile water gauges and suspended hammer water gauges. Some ships usually have water gauges installed on the bow, stern and both sides of the hull amidships. During the monitoring process, workers are usually required to check in real time.

[0003] For water gauges used to monitor the water level of oceans or fast-flowing rivers, surges often occur at their locations, and the horizontal surface fluctuates up and down. Workers cannot obtain the accurate water level by observing the water gauge, which poses certain safety hazards. Utility Model Content

[0013] The utility model is further configured that a threaded hole three is formed through the top of the end cover plate, the threaded hole three matches the external thread three, and a plurality of movable rods are fixedly connected to the top of the end cover plate.

[0014] The utility model is further configured as follows: the lower end cover comprises a chassis, a plurality of trapezoidal holes are provided at the bottom of the chassis, the trapezoidal holes are slidably matched with the movable rods, a fixing ring 2 is fixedly connected to the peripheral side surface of the chassis, and a through hole 3 is provided through the bottom of the chassis.

[0016] The utility model has the following beneficial effects:

[0017] 1. The utility model uses water pressure to introduce seawater into the transparent inner tube, and introduces air into the cavity formed between the transparent outer tube and the transparent inner tube, so that the center of gravity of the device moves downward, and it can keep floating vertically on the sea level. At the same time, when a surge occurs, the floating amplitude of the seawater in the inner tube is also small, and the flow rate of the seawater entering the transparent inner tube is controlled by the flow rate control component, reducing the impact of the seawater flowing into the transparent inner tube from the lower end cover, so that the water level height of the transparent inner tube is closer to the actual seawater height, so as to facilitate the observation of the water gauge.

[0018] 2. The utility model places an auxiliary observation piece in the inner tube. The lower half of the auxiliary observation piece is a solid metal hemisphere, and the upper half is a hollow cylindrical shell. After seawater is introduced into the transparent inner tube, the auxiliary observation piece floats vertically on the water surface in the transparent inner tube due to the gravity. When the water surface in the transparent inner tube floats, the auxiliary observation piece is little affected. In a weak light environment, the rays emitted by the indicator lights on the sides of the auxiliary observation piece can be stably irradiated on the water gauge, so that the accurate water level can be observed on the water gauge.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
