Description

Technical field:

[0001] The utility model relates to the technical field of pipeline dredging, in particular to a sampling pipeline dredging tool. Background technology:

[0002] There are many parameter measurement transmitters in power plants, such as pressure, flow, differential pressure coal mill material level, etc. One end of the sampling pipeline needs to be connected to the transmitter, and the other end needs to be directly connected to the main pipeline of the thermal system with working fluid. The corresponding parameters in the thermal system can be calculated by using the changes in the working fluid in the sampling pipeline. Only by ensuring the smooth flow of the sampling pipeline can accurate data be provided to the operating personnel, which is convenient for them to analyze and adjust the parameters. Due to the complex working conditions in the thermal system and the small diameter of the sampling pipeline, the sampling pipeline is blocked after the equipment has been running for a long time, making it impossible to obtain the working fluid in the sampling pipeline.

[0003] The existing sampling pipelines are basically 2 cm in diameter and 1.5-2 meters in length. Due to environmental reasons, the sampling and measuring devices are distributed in different positions, and some sampling pipelines are bent. For places with narrow space, when the sampling pipeline is blocked, compressed air is usually used to blow it into the sampling pipeline with an air gun to clear the blockage. However, some blockages (for example, castables) are relatively firmly adhered, and compressed air cannot remove these blockages, so that the sampling pipeline cannot be completely unblocked. Utility model content:

[0004] The purpose of the utility model is to provide a sampling pipeline dredging tool to solve the problems raised in the above background technology.

[0005] The utility model is implemented by the following technical solutions:

[0006] A sampling pipeline unclogging tool comprises: a tee pipe, a connecting rod, a clamping ring, a metal bellows and a drill bit; a connecting rod is provided in a sliding sleeve inside the vertical tube of the tee pipe, and a plurality of horizontally arranged limit slots are evenly provided on opposite sides of the connecting rod along its vertical direction, a slot with a "U"-shaped structure is provided on one side surface of the bottom of the vertical tube, the clamping ring has a "U"-shaped structure and is inserted between the limit slot and the slot, so that the bottom of the vertical tube is fixedly connected to the connecting rod, the bottom end of the connecting rod is threadedly connected to the top end of the metal bellows, and the drill bit is fixed to the bottom end of the metal bellows.

[0007] Preferably, a flat groove is further provided on the slot below the edge of the vertical tube, and the slot and the flat groove are communicated with each other.

[0008] Preferably, a shift plate is fixed to the lower surface of the middle part of the clamping ring, and the surface of the shift plate facing the opening side of the clamping ring is in contact with the vertical surface of the flat groove. After the clamping ring is inserted into the limiting groove, its arc surface coincides with the outer surface of the vertical tube.

[0009] Preferably, the three-way pipe and the connecting rod are made of metal, and the clamping ring is made of hard polyvinyl chloride.

[0010] Preferably, the diameter of the vertical pipe is the same as the diameter of the metal bellows.

[0011] The utility model has the advantages that the length of the connecting rod extending out of the vertical pipe can be adjusted through the clamping ring, and the deformation and bending characteristics of the metal bellows are utilized so that the drill bit can quickly enter the bent part of the sampling pipeline to clear the sampling pipeline, which is convenient and quick.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-5 The utility model provides a technical solution for a sampling pipeline dredging tool:

[0020] A sampling pipeline dredging tool comprises: a tee 1, a connecting rod 2, a clamping ring 3, a metal bellows 4 and a drill bit 5; wherein the tee 1 and the connecting rod 2 are made of metal, the clamping ring 3 is made of hard polyvinyl chloride, and the diameter of the vertical pipe 1.1 is the same as that of the metal bellows 4.

[0021] A connecting rod 2 is provided in a sliding sleeve inside the vertical tube 1.1 of the tee pipe 1. A plurality of horizontally arranged limit slots 2.1 are evenly provided on opposite sides of the connecting rod 2 along its vertical direction. A slot 1.2 with a "U"-shaped structure is provided on the surface of one side of the bottom of the vertical tube 1.1. The retaining ring 3 has a "U"-shaped structure and is inserted between the limit slot 2.1 and the slot 1.2, so that the bottom of the vertical tube 1.1 and the connecting rod 2 are fixedly connected, so that the extending length and storage of the connecting rod 2 in the vertical tube 1.1 are achieved, and at the same time, the connecting rod 2 itself can be prevented from rotating, so that the drill bit 5 can be rotated conveniently; the bottom end of the connecting rod 2 is threadedly connected to the top end of the metal bellows 4, and the drill bit 5 is fixed at the bottom end of the metal bellows 4.

[0022] A flat groove 1.3 is also provided on the slot 1.2 below the edge of the vertical tube 1.1, and the slot 1.2 and the flat groove 1.3 are connected. A shift plate 3.1 is fixed to the lower surface of the middle part of the clamp ring 3, and the surface of the shift plate 3.1 facing the opening side of the clamp ring 3 is in contact with the vertical surface of the flat groove 1.3. After the clamp ring 3 is inserted into the limit clamping slot 2.1, its arc surface just coincides with the outer surface of the vertical tube 1.1, so that the clamp ring 3 is not easy to fall off.

[0023] The working principle is: insert one end of the unblocking tool with the drill bit 5 into the sampling pipeline, insert the drill bit 5 into the blockage by rotating the two ends of the top of the tee pipe 1, and clear the blockage of the sampling pipeline by turning it multiple times or knocking it hard. When the sampling pipeline is bent or the space is narrow, the clamping ring 3 can be pulled out by the dial plate 3.1, the length of the connecting rod 2 can be adjusted, and then the clamping ring 3 can be inserted between the limit groove 2.1 and the slot 1.2, so that the bottom of the vertical pipe 1.1 and the connecting rod 2 are fixedly connected, and the metal bellows 4 itself can be deformed and bent.
