Abstract

The solution relates to locking devices for manhole covers of engineering networks, in particular manhole covers for sewer channels and helps prevent unauthorized persons from entering the well. Three locking elements on the inner surface of the lid, two of which are fixed rigidly, and the third, locking - with the possibility of rotation, serve to interact with mating support elements of the hatch body. Access to the locking element is blocked by a crackable seal-retainer. 7 c.p. f-ly, 8 ill.

Description

The proposal relates to locking devices for manhole covers for wells of engineering networks, in particular manhole covers for sewer channels.

Currently, basically, access to urban underground utilities is practically free through street wells with non-lockable covers.

A technical solution is known, see application for invention No. 2004132031, IPC E02D 29/14, dated 02.11.2004, publ. 04/10/2006:

A locking lid for inspection hatches, comprising a guide sleeve for a rotating screw mounted on the cover, in the lower part of which a grip in contact with the stop is mounted on the thread with the possibility of movement, and the emphasis is made on the guide sleeve.

The solution has the following disadvantages:

design complexity, high cost, complexity of maintenance and repair, insufficient reliability and protection against unauthorized opening, impossibility of reliable control of unauthorized opening.

wherein

- the device is equipped with a limiter for rotation of the third locking element mounted on the inner side of the cover;

- the head of the locking rod element is made profiled;

- the closing head of the locking rod element from the outside of the lid

the movable part is mounted with the possibility of longitudinal movement from the outer to the inner side of the lid relative to the pivoting rod element, made of a glass-like shape, including a bottom part and a side wall, the bottom part is oval-shaped in plan, shape, with a perimeter larger than the perimeter of the side wall, in the central part of the bottom part, weakening slots are made, from the inside on the bottom part there is a profiled, counter-head of the rod element, an orienting protrusion, to stke side wall on the side opposite the bottom portion formed springy latching hooks facing toward the axial line of the movable part, at the free ends of the springy latching hooks formed inclined toward the axial line of the movable part, flats;

- the movable part is made of plastic;

- the movable part is provided with an individual designation;

- the device is equipped with a rubber gasket for installation around the perimeter between the cover and the housing;

- an oval-shaped recess is made in the lid on the outside to accommodate the oval-shaped bottom of the movable part.

Description of the use of the hatch with a locking mechanism (production summary).

The manhole of the inspection well is installed on the wells of various engineering networks, the body of the manhole 1 is embedded in the roadbed so that its upper edge is flush with the canvas. A cover 2 is installed in the opening of the housing; in this case, a rubber gasket 3 is installed between the housing and the hatch in order to weaken the impact of the cover on the housing during the collision of vehicles.

In order to prevent unauthorized persons from entering the well, a latch mechanism is mounted in the lid, consisting of the following parts: the latch 4 is actually worn on the screw 8, held down by the nut 10 and the pin 11. A washer is inserted between the screw head and the lid 5. For turning the lock, i.e. . to lock and unlock the manhole cover, a hexagonal recess is made in the screw head for a hex key of the appropriate size. A seal retainer 6 is put on the screw head, which closes access to the hexagonal recess of the screw, the seal retainer can only be removed by destroying it, since its design provides springy hooks that allow you to insert the seal retainer into the appropriate seat (oval-shaped recess in the cover), however, it is impossible to remove the seal back without breaking the mentioned springy hooks - they “clicked” on the groove on the screw head. The seal retainer itself is also made oval-shaped in terms of shape for a seat in the lid. In addition, in the central part of the seal-retainer from the side facing the screw head, a reciprocal screw head, a hexagonal protrusion, is made. Thus, when installing a seal - retainer in its oval-shaped form when interacting with an oval-shaped recess in

the lid, prevents the rotation of the seal-lock, for example, when the car collides, other vibration influences.

Interacting hexagonal surfaces: on the screw head and on the inside. facing the screw head, the sides of the locking seal, in turn, prevent spontaneous opening (rotation) of the constipation 4. Therefore, the locking seal performs at least two main functions: prevents the spontaneous opening of the constipation, and a broken seal-retainer or its absence indicate that the hatch could be open. On the opposite side of the lock, two latches 7 are installed, each of which is fixed with two bolts 9. The latches, as well as the lock, prevent the lid from opening but are fixed motionless.

The correspondence between the terms of the production annotation and the terms of the formula is given below with the same positions in the drawings

three locking elements: constipation - 4 and two clamps - 7
