Abstract

The utility model discloses a hydrological observation well mouth-sealing device. A supporting structure [6] which is nearly concentric with a concrete well mouth [2] is arranged in the concrete well mouth [2] of a well [1]; a permanent seat [7] for a transmitter [4] is integrated with the supporting structure [6], and is arranged on the supporting structure [6]; a well cover [9] is arranged on the permanent seat [7]; and nuts which are matched with bolts [8] fixing the well cover [9] are arranged on the sidewall of the permanent seat [7]. The utility model has the following advantages: since the permanent seat on the supporting structure and the concrete of the well mouth are casted integrally, connection is firm and reliable; because the bolts in the counter bores of the circumference of the well cover are firmly matched with the nuts of the permanent seat and the sealing device is then buried underground, concealment is good, and the sealing device is safe and reliable and can effectively protect the safety of a logging device, a logging sensor and an transmission antenna.

Description

A kind of hydrologic observation well head locking device

Technical field

The utility model belongs to a kind of protective device of pick-up unit of hydrologic monitoring technical field, and definite saying is a kind of hydrologic observation well head locking device.

Background technology

Have the hydrogeological technical field of vital role for national economy, it is the most effective means that obtain the firsthand information that the phreatic hydrology detects.Phreatic detection generally is by probing hydrologic monitoring well, places sensor and transmitter and emitting antenna in the well and arrives each monitor node combined data then by GPS transmission signal.But because the probing well head is open, seal badly, well head and interior sensor and transmitter and antenna etc. thereof can not well be protected, so often are subjected to the erosion of sleet, artificial or non-artificial destruction etc. and cause unnecessary damage.Not only make national wealth receive loss, even more serious is that hydrogeological Monitoring Data is interrupted therefrom, the data chainning brought disappearance and have influence on the data accuracy in some areas.In order to solve the closed question of well head, adopted such as measures such as usefulness concrete complete closed well heads, though equipment has obtained protection; but; the repair and maintenance of electronic equipment such as transmitter, sensor, replacing etc. are difficulty very, through operation after a while, has not adopted substantially.Therefore the closed question that solves hydrogeology monitoring well head just seems extremely important.Designer of the present utility model has done research in earnest to this, proposed goal of the invention of the present utility model.

Summary of the invention

Goal of the invention of the present utility model puts forward for the problem that the well head that overcomes present hydrogeological monitor well can not get well sealing.A kind of hydrologic observation well head locking device promptly is provided.

Technical solution of the present utility model is to realize like this, this kind hydrologic observation well head locking device, in the concrete well head [2] of well [1], has a fixed mount [6] with well [2] essentially concentric, it above the fixed mount [6] holder [7] with the transmitter [4] of its one, be well lid [9] above the holder [7], on the sidewall of holder [7], have and fixing bolt [8] nut engaged of well lid [9].

Beneficial technical effects of the present utility model is: the holder below the fixed mount and the concrete of well head are cast for one; firm and reliable connection; well lid cooperates with nut on the holder by the bolt in the counterbore of periphery to be fixed; landfill is at below ground then; good concealment; safe and reliable, can protect the safety of well logging apparatus and logging sensor and emitting antenna effectively.

Description of drawings

Accompanying drawing is a structural profile schematic views of the present utility model.Sequence number in the accompanying drawings is described as: 1, well, 2, well head, 3, sensor cable, 4, transmitter, 5, soil, 6, fixed mount, 7, holder, 8, bolt, 9, well lid, 10, through hole, 11, emitting antenna, 12, firing cable, the angle of the center line of a, through hole [10] and well lid [9] sidewall.

Embodiment

Below in conjunction with the embodiment that provides in the accompanying drawing, structure of the present utility model and use are elaborated.With reference to accompanying drawing, this hydrologic observation well head locking device, in the concrete well head [2] of well [1], has a fixed mount [6] with well [2] essentially concentric, it above the fixed mount [6] holder [7] with the transmitter [4] of its one, be well lid [9] above the holder [7], on the sidewall of holder [7], have and fixing bolt [8] nut engaged of well lid [9].Have through hole [10] on the sidewall of well lid [9], the angle of the sidewall of the center line of through hole [10] and well lid [9] is the 30-60 degree.For the ease of construction, fixed mount, holder and well lid be cylinder body shape preferably, is best with the contour structures of four prism type.In the time of the pour concrete well head fixed mount and holder put and put in place, after the cast through maintenance, concrete solidify out into well head, holder just and well head become one.Then sensor and sensor cable are put into well together, unnecessary sensor cable can coil the lower bottom part that is positioned over holder.Transmitter antenna is fixed on the correct position of holder, then transmitter is fixed on the holder.The assembling well lid is positioned over well lid on the holder, with bolt in the well lid counterbore and the nut aligned position on the holder, tightens nut, and well lid is with regard to firm being fixed on the holder.Last earthing, above the counterbore with native landfill bolt place below the through hole of well lid, concordant substantially with the original face of land.Owing to be counterbore design, after the landfill earthing, can't see the connected mode of well lid from appearance, played the effect of security protection.The effect of through hole is the inside and outside pressure of balance hydrology monitor well, reduces the isolation decay that concrete well cover transmits for more weak GPS simultaneously.When needs overhaul transmitter, sensor, when perhaps changing operation such as battery,, the bolt in the counterbore around the lid is unclamped as long as the earthing around the well lid is pushed aside, take down well lid, that's all.Constructing operation is simple and convenient.

Claims
