RU2804096C2 - Universal manhole hatch - Google Patents

Abstract

FIELD: inspection well hatches.

SUBSTANCE: manhole hatch contains an upper cover with locks, secured by means of an internal hinge at the base of the hatch, and an inner cover. There are three spring-type locks attached to the bottom surface of the top cover. A cell phone and an electromagnetic lock are mounted in the second cover to allow the second cover to be removed after the electromagnetic relay of the cell phone vibration lock is closed. The base of the hatch is made with a groove into which a trapezoidal rubber gasket is inserted.

EFFECT: creation of a durable hatch structure with shut-off valves and the prevention of unauthorized access to the well through the hatch.

Description

The invention relates to a universal device and method for use in housing and communal services systems, during the construction of almost all facilities, when laying cable networks and communication distribution centers, cellular and government.

The hatch of inspection wells is designed for installation on inspection underground utilities: heat, gas, cable networks, sewerage and water supply. The main functions of inspection well hatches are to protect the wells and internal equipment from damage and ensure the safety of vehicular and pedestrian traffic.

Depending on the maximum loads that the hatch can withstand, they are installed on the roadway, in courtyards, on sidewalks, in industrial facilities and parking lots. Hatches are all divided into load classes, by type, by diameter, as well as by weight and height and shape: oval, square, round and others. All hatches are designed to provide access to collectors, shut-off valves, network cables and distribution devices to protect wells and drainage channels from any external damage and ensure safe vehicular and pedestrian traffic and from unauthorized access attempts. Hatch covers are designed to prevent accidents, to prevent foreign objects (subjects) from entering the hatch and unauthorized access by others.

Manhole hatches must comply with the requirements of GOST 3634-2019 and structurally consist of 2 main parts: the base and the hatch cover, which may additionally contain a second cover and fastening units. Some types of hatches use repair inserts. In addition to cast iron covers, the following are used: polymer, polymer-composite, fiberglass with filler.

There are a lot of analogues of hatches; dozens of factories produce their own devices (hatches) which are profitable for them to produce and use at various facilities. Hatches: T - s250 Chelyabinsk, TVK, LM, LSM, S, OUE, TM - 400 Borisoglebsk, VChShG GKS type T Ekaterinburg, etc.

Analogs: RU 173029 U1, RU 173030 U1, RU 173031 U1, patent 2358064, where the technical solution is increased reliability of locking the hatch cover.

Analogues: SU 173029A1 - signaling and storage devices in machines and units.

The closest analogue to the invention is a VChShG hatch type T (S250) GKS, with a secret hinge, with a lock and a trapezoidal rubber gasket with a second cover.

The purpose of the invention is to create a strong, reliable design of a hatch with shut-off valves and to prevent unauthorized access to the well through the hatch for everyone except regular specialists.

The task is solved by a multi-level locking structure: locks, latches, a trapezoidal rubber gasket and an electronic device - a cell phone with an electromagnetic locking device.

Rice. 1. Top hatch cover.

Rice. 2. Second inner cover.

Rice. 3. Hatch base.

To strengthen the structure, 6 eye bolts with holes 16 mm in diameter were used.

1 - top hatch cover.

2 - 3 spring-type locks on the bottom of the lid.

3 - free-form rotary lock.

4 - internal hinge, allowing you to open the hatch cover 180 degrees.

5 - a trapezoidal rubber gasket inserted into a machined groove in the base of the hatch.

6 - plastic plug to protect the rotary lock from dirt.

7 - hole for twist lock.

8 - second inner cover made of cast iron or steel.

9 - 3 fastenings for fixing the cover when turning to the working position.

10 - hole for a light signal from a sensor (cell phone and electromagnetic lock.

11 - hole for floating handles (pull out to the top).

12 - mechanical spring-type lock with a retractor relay for automatic opening and closing, operating via cellular communication.

13 - a push-button cell phone in a plastic bag, which, when turned on and vibrates, closes an electrical circuit to open the second cover.

14 - direction indicator for opening and closing the second inner cover.

Hatch operation and design:

There are 2 types of locks in the top cover: spring type lock - 2 and rotary lock - 3 of arbitrary shape and device. When the hatch cover is open, you can see the internal hinge - 4, which allows you to open the cover 180 degrees. A trapezoidal rubber gasket - 5 is needed to ensure a tight fit of the cover to the base and to prevent contact between the metal parts of the hatch during operation. To open the second cover - 8, you need to call the dispatcher at the office of the security company. The dispatcher opens access to the manhole by dialing the phone's SIM card number - 13, which triggers an audible alarm and vibration.

The vibration closes the electrical circuit and the electromagnetic relay retracts the mechanical lock - 12, all that remains is to turn the cover by the handles - 11, and remove the second cover. When the well hatch is open, you can remove the cell phone from the second cover and call the control room for consultation. After the conversation, you need to put the cell phone back in its place in the cover. While on the lid, the cell phone is protected by cellophane packaging. The cell phone is powered by its own battery or by a low-voltage cable that runs through wells. After the work has been done inside the well, the inner cover - 8 must be put in place and the cover must be turned by the handles - 11, and a mechanical spring-type lock will snap into place.

The invention is of interest for wells with fiber-optic communications of particular importance - government communications, FSB communications, Telecom communications, etc. This design and method of unlocking/locking the lock has no analogues, therefore, the novelty of the reliable design of the manhole hatch and the method of using a cell phone as a relay is obvious. This model is inexpensive in design and easy to use, so the industry will very quickly establish mass production. The invention involves an inventive step by using the vibration of a cell phone as a relay to close the network to open a spring-type mechanical lock.

Claims (1)
