Embodiment 1

[0035] Such as figure 1 with figure 2 As shown, a follow-up suppression transient fluctuation compensation device for water level monitoring includes: a windproof well 1, a housing 2 and a water storage mechanism.

[0036] The windproof well 1 is installed in the water body, and the windproof well 1 is connected to the water body 3 outside the well and the water body 4 inside the well. The liquid level measuring instrument 5 is installed on the windproof well 1, such as radar water level gauge and other instruments that can measure water level, and the probe of the liquid level measuring instrument 5 face down.

[0037] The casing 2 is fixedly installed in the windproof shaft 1, and the casing 2 is a sealed structure, and a cavity is provided inside the casing 2. The housing 2 is made of anti-rust material.

[0038] The water storage mechanism is installed in the casing 2, the water storage mechanism runs through the casing 2 and the windproof well 1, and communicates with...

Embodiment 2

[0045] Such as Figure 3 to Figure 10 As shown, in this embodiment, a surge suppression mechanism is provided on the basis of Embodiment 1, which is used to suppress the surge of the water body outside the well and press the water body into the water storage mechanism. The surge suppression mechanism is installed in the windproof well 1 in a floating manner. on the outside to accommodate different water heights.

[0046] Such as image 3 with Figure 4 As shown, the surge suppression mechanism is installed above the water inlet pipe 7 and close to the water inlet pipe 7 . The surge suppression mechanism includes a pressing plate 13 , a first connecting rod 14 , a second connecting rod 15 , a transmission rod 16 and a transmission shaft 17 . Pressing plate 13 floats on the water surface, and the left end of pressing plate 13 is provided with horizontal waist-shaped hole 23, and the first connecting rod 14 is pivotally connected in waist-shaped hole 23, and the other end of f...

Abstract

The invention provides a follow-up transient fluctuation suppression compensation device for water level monitoring, and the device comprises a windproof well which is installed in a water body, the windproof well is communicated with a water body outside the well and a water body inside the well, and the windproof well is provided with a liquid level measuring instrument; the shell is fixed in the windproof well, and the shell is of a sealed structure; the water storage mechanism is installed in the shell, and the water storage mechanism penetrates through the shell and the windproof well and is communicated with water outside the well and water inside the well; the water storage mechanism comprises a water storage bag, the water storage bag is a contracted elastic bag body in a free state, and surging water is pressed into the water storage bag due to water pressure change, so that the water storage bag is expanded. When surge occurs, water flows into the water storage bag, the water storage bag expands to store water due to sudden change of water pressure, and part of surge impact is eliminated; when water waves fade away, the water storage bag squeezes out water stored in the water storage bag and discharges the water to the measured water surface, and therefore the influence of surge on water surface fluctuation in the well is reduced.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, and in particular relates to a follow-up suppression transient fluctuation compensation device for water level monitoring. Background technique [0002] In water level measurement, because the water surface is affected by wind and waves will be generated, no matter whether a float water level gauge, radar water level gauge or other types of water level gauges are used, the water level measurement value cannot truly reflect the elevation of the current water level. [0003] For example, the patent with publication number CN208751660U discloses a liquid level measuring device, which includes a fixing piece, a cylinder and a probe wave measuring device. The fixing part includes a first part that is higher than the liquid level of the sewage and a second part that is connected to the first part and extends to be immersed in the sewage; the cylinder is suspended in the sewage between ...
