The specific embodiment
The utility model is further described below in conjunction with drawings and Examples.
As shown in Figures 1 to 4, groundwater monitoring wellhead protecting case of the present utility model, comprise a casing 1, the casing below can be cast in the basis, also can be fixed on the basis, be provided with a hook in the casing, so that fixation of sensor, electric wire etc. by bolt etc., casing top opening part is provided with case lid 2, is provided with anti-shielding construction 3 on casing or case lid; Casing 1 is hinged by hinge 4 in a side with case lid 2, is provided with at the box outer surface of a corresponding side with hinge and is inverted round barrel shape lock 5, and round barrel shape lock 5 can directly be welded on the casing 1, also can be welded on the casing 1 by connector as shown in Figure 1; Round barrel shape lock 5 central upper portion places are provided with through hole, and the axis of this through hole overlaps with the axis of round barrel shape lock; In described case lid soffit and the corresponding position of through hole, round barrel shape lock top to being arranged with screw rod 6, the diameter of the diameter of this screw rod and length and through hole is suitable, to guarantee that case lid unaffected and case lid when opening or closing can pass through hole and stretch to certain-length in the lock when closing; Also comprise one with the suitable cylindrical tapered end 7 of round barrel shape lock inner surface, to having and the suitable screw 71 of screw rod, be provided with lockhole 72 in the tapered end upper surface middle part at the tapered end soffit; Also comprise one with the suitable tapered end key 8 of lockhole.
Like this, at needs case lid 2 under lock and key the time, is only needed case lid 2 is covered on casing 1, the through hole that makes screw rod 6 on the case lid 2 pass lock 5 tops stretches in the lock 5, then tapered end 7 is filled in from bottom to up to lock 5, and by tapered end key 8 tapered end 7 and screw rod 6 are screwed and to get final product.When needs are opened case lid, otherwise then, with the tapered end key tapered end is screwed off and case lid can be opened from screw rod earlier.Because the tapered end of this structure is arranged in the tubbiness lock, and opening is down, can prevent that others from prying open it by instrument etc., and the relative screw rod diameter of lock is bigger, the difficulty that is cut is also bigger, but overall structure is really very simple, and easy to use.
The form of structure of above-mentioned lockhole 72 is more, can square hole as it, also can be two circular holes that keep at a certain distance away, get final product and only need do to become accordingly with square hole or two corresponding square columns of circular hole or fork configuration with respect to tapered end key 8, but the pick-proof poor-performing of the lockhole of this structure, the thief can open by instruments such as screwdriver iron wires, in order to strengthen the pick-proof effect further, described lockhole 72 is specially: ring diameter is greater than the annular recess of tapered end top screwhole diameter in the tapered end soffit upwards is provided with, and tapered end axially is provided with a groove that extends to the tapered end soffit at least in the periphery upper edge of annular recess; Described tapered end key 8 is specially: a cylindrical handle 81, be shaped on handle 82 at an end of handle, and so that operate, also can as shown in the figure through hole be set on its handle certainly, so that operate by iron rod etc. by spanner etc.; The other end one of handle is shaped on the annular projection 83 suitable with described annular recess, is shaped on described annular projection and the suitable convex tendon of described groove.Like this, in use, only need tapered end convex tendon and relative insertion of groove on the tapered end on the key, can open or screw tapered end by instrument twisting grip then, after using, the tapered end key is extracted, the space of the annular recess of tapered end is comparatively narrow and small to be difficult for by insertions such as screwdrivers, do not have by means of the power part even insert it yet, thereby reach the purpose of pick-proof.
Certainly, the number and the shape of the groove in the above-mentioned annular recess are not limit, so that open and lock, be convenient to the insertion of tapered end key and extract to be as the criterion.For easy to process, can axially be provided with the arc groove that at least one pair of extends to the tapered end soffit relatively at the upper edge, the corresponding position of inside and outside periphery of annular recess tapered end, like this, when groove is more shallow, be difficult to find out this two grooves from the outside, disguise is stronger, can further strengthen anti-theft effect; These two relative arc grooves can form by drill bit annular recess inside and outside periphery between the center boring of a diameter greater than the inside and outside periphery spacing of annular recess; Relative, above-mentioned tapered end key 8 can be provided with opening with the corresponding position of arc groove on described annular projection, in described opening, be provided with the suitable steel ball 84 of arc groove and realize, as shown in Figure 4, the quantity of its steel ball, size and the size of annular recess and the depth of groove etc. have relation.Like this, the processing of tapered end and tapered end key is comparatively simple.
Further improve as the utility model ground, extend upward in above-mentioned tapered end upper surface middle part and be formed with cylindrical boss 73, the through hole internal diameter on the external diameter of described boss and tubbiness lock top is suitable.Can strengthen the intensity of tubbiness lock like this, lock be sawed evil idea etc. to prevent the thief in the through hole.
Further improve as the utility model ground, also can be provided with ring-type pick-proof guard ring 9 at above-mentioned case lid soffit and the corresponding position of tubbiness lock, the internal diameter and the tubbiness lock external diameter of described ring-type pick-proof guard ring are suitable.Like this, can effectively not avoid theft the person with between the insertion case lid of crow bar and so on and the lock that its sled is bad.
Above-mentioned anti-shielding construction can be diversified, for example, the simplest, can can reach anti-shield effectiveness boring many accessibke porosities on casing or the case lid, but rainproof like this effect is relatively poor, is unfavorable for open-air long-term the use, improve further as of the present utility model, be shaped on anti-shield opening on the case lid above the described casing, be provided with nylon cover plate 31 in described anti-shield opening, described nylon cover plate and anti-shield opening are by the sealing ring water-stop.
In summary, the utility model groundwater monitoring wellhead protecting case overall structure is simple, easy to use, and pick-proof, anti-saw anti-theft feature are stronger.
