Description

The utility model relates to plumbing equipment, in particular, to devices for installing and removing a plug in a sewer, and can be used to remotely disconnect apartment sewer outlets from a common sewer system.

A device for blocking sewage (RU 106713 U1, published July 20, 2011) is known, comprising a gripping mechanism mounted on a support rod and a removable rod connected to the support rod. The gripping mechanism consists of two concentrically mounted tubes, spring-loaded in the longitudinal direction, the opposite ends of which are connected by means of longitudinal rods pivotally mounted along the circumferences of the ends and pivotally connected to each other. At the same time, at the junction of the rods, the grips contacting the hooks of the plug are fixed to each other.

The disadvantages of the analogue include the fragility and fragility of the device, due to the fact that the gripping mechanism is mounted on a support rod, which does not have sufficient rigidity to work in complex, heavily clogged sections of the sewer riser, is not protected from environmental influences.

A device is known for installing and removing a plug on sewer pipes, (RU 117561 U1, published on June 27, 2012), taken as the closest analogue, including a support rod, on which a gripping mechanism is mounted, made in the form of a fixed and movable elements, on which the rods are articulated , pivotally connected to each other, while on the rods in the area of the hinged connection of the rods, the grips are fixed, and a video camera is fixed on the support rod. The gripping mechanism is connected by a helical gear to an electric motor fixed to the support rod.

The disadvantage of the prototype is fragility and fragility, due to the fact that the gripping mechanism, electric motor and video camera are mounted on a support rod equipped with a flexible element that does not have sufficient rigidity to work in complex, heavily clogged sections of the sewer riser. The electric motor and the movable part of the gripping mechanism, mounted on the support rod are not protected from the external environment, which also leads to their destruction.

The technical result of the claimed utility model is to increase the service life of the device, due to the placement of the gripping mechanism and electric motor in a metal case.

The specified technical result is achieved by the fact that in the device for installing and removing the plug on the sewer, containing a gripping mechanism, the rods of which are pivotally connected to each other, while on the rods in the area of the swivel are fixed grippers for the plug, the video camera, the gripping mechanism is fixed using a screw gears with an electric motor and is made of movable and fixed parts, moreover, some rods in the gripping mechanism are pivotally fixed to the moving part of the gripping mechanism, while others are fixed the second part of the gripping mechanism, inserted metal housing, one part of which is fastened the motor and the movable part of the gripping mechanism and its fixed part and a video camera mounted in another part of the metal body. The metal case contains sealing elements made in the form of seals.

The essence of the claimed device for blocking sewage is that due to the introduction of a metal case, which houses the electric motor, a video camera and a gripping mechanism and the implementation of part of the body with sealing elements, the service life of the entire device is increased.

In FIG. 1 shows a general view of the device assembly, FIG. 2 is a section AA, in FIG. 3 - view B, where the following notation is accepted:

1 - a stub;

2 - stub hooks;

3 - stopper;

4 - metal case;

10 - helical gear;

11 - video camera.

12 - rod;

13 - gripping mechanism;

14 - sealing elements.

a device for installing and removing the plug on the sewer, contains a plug 1 with hooks 2 and a stopper 3, a metal housing 4, a gripping mechanism 13 with grippers for the plug 5, movable 7, and stationary 8 parts, an electric motor 9, a video camera 11. Traction of the gripping mechanism 6 are pivotally interconnected. Clamps 5 for the plug 1 are fixed on the rods 6 in the area of the swivel joint. An electric motor 9 is fixed in the metal housing 4, the plug 1 is made with a longitudinal section along the generatrix and provided with at least two hooks 2 installed around the circumference of its cross section. The gripping mechanism 13 is fixed using a helical gear 10 with an electric motor 9. The gripping mechanism 13 is made of movable 7 and stationary 8 parts, moreover, one rod 6 in the gripping mechanism 13 is pivotally fixed to the movable part 7 of the gripping mechanism 13, and others to the fixed part of the gripping mechanism 8. The electric motor 9 and the movable part of the gripping mechanism 13 are fixed in one part of the metal housing 4, and the fixed part 8 of the gripping mechanism 13 and the video camera 11 are fixed in another part of the metal housing 4. Metal the housing 4 contains sealing elements 14, made in the form of seals.

The device operates as follows. The operator inserts the plug 1 into the device by means of grippers 5 and hooks 2, then includes an electric motor 9, which lifts the movable part of the gripping mechanism 7 through the screw gear 10 relative to the fixed part 8, and thereby bends the plug 1 to a diameter less than the diameter through the rods 6 sewer riser. A device for blocking sewage using a rod 12 is lowered into the riser, while the achievement of the sewer drain of the apartment of the desired floor is controlled along the length of the rod. The camcorder 11, mounted in the metal housing of the gripping mechanism 4, transmits images of the gripping mechanism 13 with a plug 1 and a tap hole fixed therein. After positioning the bent plug 1, opposite the sewer outlet, the operator turns on the electric motor 9 in the opposite direction of rotation, the movable part of the gripper 7 and the stationary part of the gripper 8 are moved and through the rods 6 they begin to weaken the bend of the plug 1 and, finally, the plug 1 is pressed against the inner surface of the riser, closing the outlet hole. A device for blocking sewage is disconnected from the hooks 2 of the plug 1 and is removed from the riser. Removing the plug occurs in the reverse order.

Thus, due to the fact that in the inventive utility model, the gripping mechanism, electric motor and video camera are fixed and placed in a metal case, part of which is made with sealing elements, a technical result is achieved - increasing the service life of the mechanism. This advantage, unlike the prototype, will improve the operation of the gripping mechanism in an aggressive environment of sewer risers and, in addition, the rigidity of the metal body will ensure the durability of the device in hard-to-reach clogged pipelines.
