For example, chinese patent publication No. CN201155312Y discloses a wellhead protection box for underground water monitoring, which includes a box body, a box cover is arranged at an opening above the box body, and an anti-shielding structure is arranged on the box body or the box cover; the box body and the box cover are hinged through a hinge at one side, an inverted cylindrical lock seat is arranged on the outer surface of the box body at the side corresponding to the hinge, a through hole is arranged at the center of the upper part of the cylindrical lock seat, and the central axis of the through hole is superposed with the central axis of the cylindrical lock seat; a screw is arranged downwards at the position of the lower surface of the box cover corresponding to the through hole at the upper part of the cylindrical lock base, the box cover also comprises a cylindrical lock head matched with the inner surface of the cylindrical lock base, a screw hole matched with the screw is arranged downwards in the middle of the upper surface of the lock head, and a lock hole is arranged at the lower surface of the lock head; the lock also comprises a lock head key matched with the lock hole. After adopting above-mentioned structure, overall structure is simple, convenient to use, and the theftproof performance is strong.
However, due to the existence of the box body, the operation or the maintenance of the related equipment for measurement is obstructed by the box body, so that the operation is inconvenient and the detection is influenced.
Disclosure of Invention
The invention aims to provide a protection structure of an underground water monitoring well, which has the advantage of facilitating the operation or maintenance of relevant equipment for measurement.
The technical purpose of the invention is realized by the following technical scheme:
the utility model provides an underground water monitoring well protection architecture, includes the well body, the well head department of the well body is provided with the dustcoat, the dustcoat top is provided with the top cap, be provided with fixed mounting between top cap and the dustcoat, set up on the well body and supply the vertical gliding spout of dustcoat, be provided with vertical gliding montant and the salient dustcoat top surface of montant one end on the dustcoat, be provided with in the dustcoat and supply the gliding cavity of montant, sliding connection has the fixture block on the cavity inner wall, be provided with on the spout inner wall and just keep the dustcoat to be in the outside draw-in groove of spout with the fixture block joint, be provided with on the montant and link gear that the fixture block removed the draw-in groove when moving under it.
Through setting up like this, when not monitoring groundwater, the top cap lid is on the dustcoat, the top cap pushes down the montant and links in the fixture block card goes into the draw-in groove, the dustcoat can be by the spacing circumstances of accomodating in the spout that can not appear descending this moment, and the dustcoat can play good guard action to the relevant equipment of well head department, and after opening the top cap, the montant can resume the normal position under the piece effect that resets, the fixture block no longer with the draw-in groove joint this moment, and then can accomodate the spout with the dustcoat gliding, the dustcoat can not shelter from the relevant equipment of well head department this moment, be convenient for to the operation or the maintenance.
The invention further provides that: the linkage mechanism comprises a wedge-shaped surface which is arranged at the bottom end of the vertical rod and abutted against the fixture block, the reset piece comprises a first spring, one end of the first spring is fixed with the inner wall of the cavity, and the other end of the first spring is fixed with the fixture block.
Through the setting of wedge, can exert force on the wedge when the montant moves down, and then realize spacing to the dustcoat in drive fixture block horizontal migration and the card income draw-in groove, open the back at the apron, its fixture block is deviate from the draw-in groove and drive montant and resume the normal position under the effect of first spring when the montant does not have the atress, in the spout can be accomodate to the dustcoat gliding this moment, simple structure just realizes the linkage of montant and fixture block.
The invention further provides that: the linkage mechanism comprises a connecting rod, one end of the connecting rod is hinged to the fixture block, the other end of the connecting rod is hinged to the vertical rod, the hinged point of the connecting rod and the vertical rod is higher than the hinged point of the fixture block, the reset piece comprises a second spring, and the two ends of the second spring are fixed to the vertical rod and the bottom wall of the cavity respectively.
Like this move down the in-process at the montant with the help of the connecting rod with do all can exert on the fixture block to drive fixture block horizontal migration card go into the draw-in groove, and open the back at the apron, its normal position that resumes under the effect of second spring when the montant does not have the atress, and shift out the draw-in groove with the help of connecting rod pulling fixture block simultaneously and break away from the joint, the dustcoat can slide down at this moment and accomodate the spout in, simple structure just realizes the linkage of montant and fixture block.
The invention further provides that: the lateral wall of the outer cover is provided with a groove, a supporting bar is hinged in the groove, and when the supporting bar is turned out to abut against the top wall of a well mouth, the clamping block and the clamping groove are located at corresponding positions.
Through the setting of support bar, when need cover the top cap after the completion to the monitoring of groundwater, lift the back with the dustcoat, can follow the support bar and roll out and support the moving down of restricting the dustcoat with the help of it, the fixture block is in corresponding the position with the draw-in groove this moment, just so cover the in-process of top cap and just need not the hand and operate the dustcoat always to the operation of being more convenient for, and the operation is light laborsaving more.
The invention further provides that: the fixture block is symmetrically provided with two fixture blocks, and inclined planes matched with the wedge-shaped surfaces are arranged on the fixture blocks.
The fixture block that at first the symmetry set up makes the steadiness of joint more secure, with the help of the setting on inclined plane in addition for the fixture block can be better with the montant contact, and the montant tip can be better get into between two fixture blocks and promote both horizontal migration.
The invention further provides that: the outer cover is provided with a vertical guide strip, and the inner wall of the sliding groove is provided with a guide groove matched with the guide strip.
The effect of direction can be realized through the cooperation of conducting bar and guide slot, can play the spacing effect of circumference to the dustcoat moreover, and then gliding in-process can not exist to rotate about the dustcoat and lead to fixture block and draw-in groove not to the last condition to appear.
The invention further provides that: the top end of the outer cover is provided with a convex ring, and the outer diameter of the convex ring is larger than that of the well body.
Because the external diameter of bulge loop is greater than the well body to people can hand the bulge loop and operate when needing to lift the dustcoat, the operation of the dustcoat of being convenient for more.
