Description

Device for preventing sundries from falling off during pressure pipeline repair

Technical Field

The utility model relates to a clean protection field is taken over to the power station container, specifically is an inside debris device that drops of preventing during repair pipeline under pressure.

Background

The normal operation of the power station is basically a reaction process of converting chemical energy of raw materials into heat energy, converting the heat energy into mechanical energy for driving power generation equipment to rotate and finally generating electric energy; the series of reactions and transfers are mostly realized by means of a pressure vessel and a pressure pipeline. Therefore, ensuring that the respective containers and pipes are clean is an important prerequisite for their functioning.

However, due to the influence of various factors in the construction process, such as poor personnel protection consciousness, tool failure, insufficiently clean construction environment and the like, when in-situ repair is carried out, the situation that the pipeline is blocked due to the fact that a grinding head of an internal grinding machine or other sundries fall into the pipeline is often caused, even the phenomenon that the pipeline bursts due to the fact that sundries are not checked and cleaned out of a high-pressure pipeline of a boiler is caused during the operation of the boiler because high-pressure media are blocked, the unit is forced to be shut down for rush repair, the normal operation of the unit is influenced, and extra maintenance cost is wasted.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an inside debris device that drops of preventing during repair pipeline under pressure, its easy dismounting, can be when repairing the pipeline, through blocking a section of thick bamboo shutoff pipeline in order to ensure that debris can not fall into the pipeline, guarantee the normal operating of equipment, reduce extra cost of maintenance to collect the debris that drop through blocking a section of thick bamboo, make things convenient for the recovery processing of debris.

The utility model discloses a realize above-mentioned purpose, realize through following technical scheme:

the device for preventing sundries from falling off in the process of repairing the pressure pipeline comprises a blocking cylinder inserted into the pipeline, wherein the top of the blocking cylinder is open, a lifting handle is arranged on the blocking cylinder, a fastening device is arranged on the outer wall of the blocking cylinder, and the blocking cylinder is fixed in the pipeline through the fastening device.

Furthermore, the handle comprises a connecting rod arranged at the bottom in the blocking cylinder, and a handle is arranged at the top end of the connecting rod.

Furthermore, the fastening device is a plurality of fastening bolts which penetrate through the outer wall of the blocking cylinder and are in threaded connection with the outer wall of the blocking cylinder.

Furthermore, the blocking cylinder is provided with a plurality of blocking cylinders, and the diameters of the blocking cylinders are different.

Contrast prior art, the beneficial effects of the utility model reside in that:

when the connecting pipe of the closed container is polished, the blocking cylinder is inserted into the pipeline, the blocking cylinder is fixed in the pipeline through the fastening device, construction can be conducted, sundries generated in the construction process can fall into the blocking cylinder to be intercepted and collected, the phenomenon that the sundries fall into the pipeline to affect normal use of equipment is avoided, extra maintenance cost is reduced, the fastening device is loosened after construction, the blocking cylinder can be taken out through the handle, the sundries collected in the blocking cylinder are treated in a unified mode, the use is convenient, the effect is obvious, and the connecting pipe of the closed container is easy to produce, manufacture and popularize and use.

Reference numerals shown in the drawings:

1. a handle; 2. blocking the cylinder; 3. fastening a bolt; 4. a connecting rod.

Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.

An inside debris device that drops of preventing during repair pipeline under pressure, major structure include with the inside block a section of thick bamboo 2 of pegging graft of pipeline, block a section of thick bamboo 2 can with the inside interference fit of pipeline or clearance fit, guarantee to block the interval minimizing of a 2 outer walls and pipeline inner wall, prevent that debris from blocking in the space between a 2 outer walls and the pipeline inner wall falls into the pipeline, block 2 open-tops of a section of thick bamboo for collect the debris that drop in the work progress, block and be equipped with the handle on a 2, be convenient for take and place and block a section of thick bamboo 2, block and be equipped with fastener on a 2 outer walls of a section of thick bamboo, through fastener will block a section of thick bamboo 2 and fix in the pipeline, prevent to block that a section of thick bamboo 2 from dropping and causing the jam in the pipeline.

Preferably, the handle comprises a connecting rod 4 arranged at the bottom in the blocking cylinder 2, the top end of the connecting rod 4 is provided with the handle 1, the distance between the handle 1 and the blocking cylinder 2 is increased through the connecting rod 4, and the blocking cylinder 2 can be conveniently inserted into the pipeline and installed.

Preferably, the fastening devices are a plurality of fastening bolts 3 penetrating through the outer wall of the blocking cylinder 2 and in threaded connection with the outer wall of the blocking cylinder 2, and the end parts of the fastening bolts 3 can be in pressing contact with the inner wall of the pipeline, so that the blocking cylinder 2 can be installed in the pipeline by loosening and fastening the fastening bolts 3, or the blocking cylinder 2 can be detached from the pipeline, and the operation is convenient and the installation is firm.

Preferably, the blocking cylinder 2 is provided with a plurality of blocking cylinders, the blocking cylinders 2 are different in diameter, the blocking cylinders can be suitable for pipelines with different diameters, and the blocking cylinder is wider in application range.

The using method comprises the following steps: selecting a blocking cylinder 2 with a proper diameter specification according to the inner diameter of the pressure pipeline, inserting the blocking cylinder 2 into the pipeline through a handle, screwing a fastening bolt 3, fixing the blocking cylinder 2 into the pipeline, and starting the repair work of the pipeline; after the repair is finished, the fastening bolt 3 is loosened, the blocking cylinder 2 is taken out of the pipeline through the lifting handle, and sundries collected in the blocking cylinder 2 are treated.
