Description

Multifunctional Pipeline Leak Stopper

technical field

The utility model relates to a mechanical device, in particular to a leakage plugging device for damaged ship pipelines.

Background technique

There are many kinds of pipelines on ships, mainly fresh water pipes, seawater pipes, air pressure pipes, steam pipes, fuel pipes, and the pressure of the pipes is relatively high.

Due to the special mission of the ship, the pipeline will be damaged and leaked when it is hit by the enemy's shells during combat, or cracks will occur due to the long-term decay of the pipeline, which poses a serious threat to the safety and combat effectiveness of the ship. Fast and firm pipeline Plugging has become a key issue. Therefore, people have invented many kinds of leak-stopping devices for pipelines, but they are complicated to operate, the speed of leak-stopping is slow, and the leakage is serious, especially its pressure of steam pipeline is higher, and existing leak-stopping devices are difficult to stop. In addition, due to the narrow space between the pipelines on the ship, it is more difficult for the existing leak stopper to stop the leak, so the existing leak stopper is not suitable for blocking the damage of the pipeline with high pressure and narrow space. The multifunctional leak stopper of the utility model is a way of plugging pipelines by using the screw rod on the pressure plate to carry out top pressure, which effectively solves the above-mentioned difficulties. So far, this kind of multi-functional pipeline leak stopper has not been seen on ships at home and abroad, and there is no record in the patent literature.

Contents of the invention

The purpose of this utility model is to provide a multi-functional pipeline leak stopper used on ships and civilian ships. It uses chains to bypass damaged pipelines, and binds the cross arm on the screw rod, and uses the screw rod on the cross arm to press The pressure plate under the screw is a way to make the seal under the pressure plate firmly press against the damaged opening of the pipeline to stop leakage.

The multifunctional pipeline leak stopper has good plugging effect, fast speed, convenient disassembly and assembly, simple operation, safety and reliability, and is a pipeline leak stopper that can be operated by one person.

In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a multifunctional pipeline leak stopper, which is characterized in that: it includes a cross arm and a threaded hole in the center of the cross arm, and a screw is bolted in the threaded hole, and the screw rod The lower end is connected with the movable block through the bearing. Two positioning shafts are installed on both sides of the movable block. The positioning shaft moves up and down in the positioning hole of the cross arm. There is a groove at the bottom of the movable block, and the pressure plate is under the groove. The connection is connected by inserting the protruding strip on the pressing plate into the groove of the movable block and positioning it with a spring pin. There is a chain groove on one side of the cross arm, and a chain is hung inside, and a chain safety buckle is installed, which prevents the chain from falling off from the cross arm. In addition, there are two left and right hooks on the pressure plate, which are used for plugging narrow pipes. One end of the two chains can be hung in the chain grooves on both sides of the cross arm, and the other two ends are respectively hung on the two sides of the pressure plate. Another plugging method is carried out on the two hooks.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 1 is the front view of the utility model structure.

FIG. 2 is a top view of FIG. 1 .

In the figure: 1-cross arm, 2-positioning shaft, 3-movable block, 4-screw, 5-pressure plate, 6-seal filler, 7-chain, 8-chain groove, 9-chain safety buckle, 10-hook, 11 Bearing, 12-spring pin, 13-positioning hole, 14 grooves, 15 protruding strips are formed.

Detailed ways

In conjunction with accompanying drawing 1, Fig. 2, the utility model embodiment is described further. A multifunctional leak stopper for pipelines as shown in the accompanying drawings is characterized in that: there is a threaded hole in the center of the cross arm 1, which is bolted with a screw 4, and the lower end of the screw 4 is connected with the movable block 3 through the bearing 11, and the movable Two positioning shafts 2 are installed on both sides of the block 3, and the positioning shaft 2 moves up and down in the positioning hole 13 of the cross arm. There is a groove 14 at the bottom of the movable block 3, and the pressing plate 5 is below the groove 14. Connection is to insert in the groove 14 of movable block 3 by the protruding strip 15 on the pressing plate 5 and connect with spring pin 12 location. One side of the cross arm 1 has a chain groove 8, the inside is hung with a chain 7, and a chain safety buckle 9 is housed, and the safety buckle 9 makes the chain 7 not come off with the chain groove 8.

When plugging, place the pressure plate 5 on the damaged opening of the pipeline, pass the chain 7 around the pipeline and hang it in the chain groove 8 on the other side of the cross arm, turn the screw 4 clockwise, the screw 4 goes down, and presses the movable block 3 descending, pressing plate 5 follows descending, and this makes the sealing packing 6 below pressing plate 5 firmly press on the damaged opening, and completes pipeline damage plugging.

During dismounting, screw rod 4 is turned counterclockwise, movable block 3 goes up, pressing plate 5 goes up along with, takes off the chain 7 that hangs in chain groove 8 li, pulls down multifunctional pipeline leak stopper and gets final product.

When the periphery of the damaged pipe is narrow, respectively hang one end of the two chains in the chain grooves 8 on both sides of the cross arm 1, and hang the other two ends on the two hooks 10 on the left and right sides of the pressure plate 4 respectively, and The pressure plate 5 is placed on the damaged opening, the movable block 3 is placed on the pipe corresponding to the damaged opening, the screw 4 is screwed clockwise, and the movable block 3 goes down until the chain 7 is tightened, at this time the seal packing 6 under the pressure plate 4 is firm Press against the damaged opening to complete the plugging of the damaged pipeline.
