Embodiment Construction

[0007] The structure and use of the present invention will be described in detail below in conjunction with the embodiments given in the accompanying drawings. Referring to the accompanying drawings, the hydrological observation wellhead sealing device has a fixed frame [6] that is basically concentric with the well [2] in the concrete wellhead [2] of the well [1], and the top of the fixed frame [6] is integrated with it The fixed seat [7] of the transmitter [4], the top of the fixed seat [7] is the well cover [9], on the side wall of the fixed seat [7] there is a nut that cooperates with the bolt [8] of the fixed well cover [9] . There is a through hole [10] on the side wall of the well cover [9], and the angle between the center line of the through hole [10] and the side wall of the well cover [9] is 30-60 degrees. When pouring the concrete wellhead, put the fixed frame and the fixed seat in place, after pouring, the concrete is cured and solidified to form the wellhead, an...

Abstract

The invention discloses a hydraulic observation well head sealing device. The inside of a concrete well head [2] of a well [1] is provided with a fixed mount [6] basically concentric with a well [2]; the upper side of the fixed mount [6] is provided with a permanent seat [7] of a transmitter [4] which is integrated into a whole with the fixed mount; the upper side of the permanent seat [7] is provided with a well lid [9]; and the side wall of the permanent seat [7] is provided with nuts matched with bolts [8] of the well lid [9]. The sealing device has the advantages of the permanent seat on the lower side of the fixed mount and concrete on the well head are cast into a whole and are connected firmly and reliably; and the well lid is matched and fixed with the nuts on the permanent seat through the bolts in counter bores on the periphery, and are buried underground. The sealing device has good concealing property, safety and reliability, and can effectively protect the safety of a logging device, a logging sensor and a transmitting antennal.

Description

technical field [0001] The invention belongs to a protection device for a detection device in the technical field of hydrological monitoring, in particular to a wellhead sealing device for hydrological observation. Background technique [0002] For the field of hydrogeological technology, which plays an important role in the national economy, the hydrological detection of groundwater is the most effective means to obtain first-hand information. The detection of groundwater is generally done by drilling hydrological monitoring wells, placing sensors and transmitters in the wells, and transmitting antennas to transmit signals to each monitoring node through GPS and then aggregate the data. However, because the drilling wellhead is open and not well sealed, the wellhead and its sensors, transmitters and antennas cannot be well protected, so it is often eroded by rain and snow, and caused unnecessary losses by man-made or non-man-made damage . Not only the loss of national pro...
