Wellhead protection device for underground water monitoring and using method

Abstract

The invention discloses a wellhead protection device for underground water monitoring and a using method. The wellhead protection device comprises a base and a power distribution cabinet, wherein an upper shell is welded to the inner side wall of the base, a first lantern ring is welded to the lower surface of the upper shell, and five arc-shaped tooth doors are hinged to the inner side wall of the first lantern ring through pin shafts. A gear train system composed of a driving gear, five sets of driven gears and a double-sided gear ring is utilized, and mechanical linkage between a rocker arm and the first lantern ring is matched, so that opening and closing of the five sets of arc-shaped tooth doors at the wellhead position are achieved; a fingerprint lock is used for being matched with a power distribution box to achieve anti-theft control, all transmission mechanisms are located in the whole device, and seamless fit of an external door body can effectively prevent man-made prying damage, so that the requirement for effectively protecting a wellhead is met; and an annular guide rail, a second lantern ring and a lower shell mechanism which are carried in the mechanisms can also ensure high-strength bearing and the service life of the transmission mechanisms, and the economic requirement and the using requirement are met.

Description

technical field [0001] The invention relates to the technical field of wellhead protection devices, in particular to a wellhead protection device for groundwater monitoring and a use method thereof. Background technique [0002] On the one hand, the role of groundwater monitoring is to monitor and manage water resources in a unified manner, so as to ensure the normal development of the ecological environment. On the other hand, it provides the most basic reference materials for engineering construction decisions; Timely understanding of the basic change characteristics of groundwater, once a special situation occurs, can quickly take effective measures to control it; the groundwater monitoring work in the new era is also of great significance to the prevention of geological disasters and the protection of the social environment. This work is not only a basic part of hydrological supervision , is an important content of water resource monitoring, so it has been valued by many...

AI Technical Summary

Problems solved by technology

[0003] At present, most groundwater monitoring is carried out by means of vertical well sampling, and this type of wellhead benefits from the standardization of drilling equipment. Therefore, C-250 wells are commonly used in groundwater monitoring wells across the country. This type of well is often equipped with automatic monitoring, Sampling and other equipment, so most of the wellheads currently monitoring groundwater will be equipped with protective facilities to prevent the environment in the well from being disturbed by external natural factors or human factors, and at the same time serve the purpose of protecting valuable groundwater monitoring and sampling equipment; but the current wellhead protection facilities exist Low reliability, easy to be destroyed, high equipment theft rate and many other disadvantages
