Description

Technical Field

[0001] The utility model belongs to the field of mechanical equipment, relates to the field of pipe network leakage plugging equipment, and specifically relates to an emergency leakage plugging device for a heating pipe network. Background Art

[0002] When a thermal power plant provides centralized heating to users, it needs to use a heating pipe network to transport the thermal energy of the thermal power plant to the user end through pipes. When the heating pipes of the heating network leak, it will cause heat loss, reduce heating efficiency, increase the energy consumption of the thermal power plant, and cause insufficient heating at the user end. It will also cause the pressure in the heating network system to drop, ultimately affecting the stable operation of the heating system. Therefore, it is necessary to plug the leaking heating pipes.

[0003] Heating pipeline leakage is characterized by uncertainty, and completely repairing it will involve complex repair work, which will take a long time to deal with and affect the heating supply at the user end. Therefore, when a heating pipeline leaks, emergency disposal plans are often adopted to enable operators to control pipeline leakage in the shortest time to avoid worsening of the situation and minimize the impact on users.

[0004] At present, when emergency plugging is performed on heating pipelines, the steel belt binding method is usually used for plugging. The steel belt plugger is put on the leaking pipeline, and the leak is plugged by tightening the bolts and gaskets. However, tightening the bolts requires the use of tools such as wrenches, which is cumbersome and affects the plugging efficiency. Utility Model Content

[0005] The utility model provides an emergency plugging device for a heating pipe network to solve the technical problem that the operation is cumbersome and the plugging efficiency is reduced when plugging a heating pipe with tools. After being wound, the heat shrinkable rope tightens the first arc piece and the second arc piece on the pipe, and uses its heat shrinkage to ensure the tightening effect, thereby plugging the pipe without the need for additional tools, and the operation is simple and efficient.

[0006] The technical solution adopted by the utility model is: to provide an emergency leak-plugging device for a heating pipe network, comprising a first arc-shaped piece and a second arc-shaped piece, the inner arc walls of the first arc-shaped piece and the second arc-shaped piece are fixedly fitted with rubber pads; the outer arc wall of the first arc-shaped piece is provided with at least two heat shrink ropes along the length direction; the outer arc wall of the second arc-shaped piece is provided with at least two connecting shafts along the length direction, the connecting shafts respectively correspond to the number and positions of the heat shrink ropes, and the connecting shaft and the second arc-shaped piece are unidirectionally rotatably installed; a straight rod is provided at the free end of the connecting shaft, the middle part of the straight rod is fixedly connected to the connecting shaft, and the two ends of the straight rod are respectively fixedly connected to the two ends of the heat shrink rope.

[0007] The rubber pad is attached to the pipeline through the first arc piece and the second arc piece. After passing around the first arc piece, the two ends of the heat shrink rope are connected to the straight rod on the connecting shaft, and the connecting shaft is rotated with the help of the straight rod. The straight rod makes the rotation of the connecting shaft labor-saving and simple. The heat shrink rope is wound around the connecting shaft as the straight rod rotates, so that the heat shrink rope is continuously contracted to tighten the first arc piece and the second arc piece, and the rubber pad is tightly attached to the pipeline, so as to block the leakage point of the pipeline and protect the pipeline, avoiding the first arc piece and the second arc piece from causing damage to the pipeline. The use is flexible and efficient. The one-way rotation of the connecting shaft can avoid the loosening of the heat shrink rope and ensure the firmness of the first arc piece and the second arc piece. In addition, when the pipeline transports heat energy, the heat will be conducted to the heat shrink rope, causing it to shrink due to the heat, further tightening the first arc piece and the second arc piece, and making it more reliable to use.

[0008] To further optimize the technical solution, the outer wall of the connecting shaft is sleeved with a one-way bearing, and the one-way bearing is fixedly installed with the second arc-shaped piece by means of an assembly part.

[0009] The connecting shaft is unidirectionally rotatably mounted on the second arc-shaped piece by means of a one-way bearing, thereby simplifying the assembly structure and ensuring the stability and reliability of use.

[0010] To further optimize the technical solution, the assembly includes a sleeve arranged outside the connecting shaft, the sleeve is fixedly installed with the second arc-shaped piece, and the one-way bearing is fixedly sleeved with the sleeve.

[0011] The one-way bearing is assembled on the second arc-shaped piece with the help of a sleeve. The assembly is simple and the use is stable. The sleeve is sleeved on the outside of the connecting shaft. After the connecting shaft is rotated, the heat shrink rope is wound along the sleeve to avoid interference with the use of the one-way bearing and ensure smooth use. The sleeve protects the one-way bearing to avoid damage and extend its service life.

[0012] To further optimize the technical solution, a slot is provided in the middle of the straight rod, and the connecting shaft is plugged into the slot and fixed by welding.

[0013] The straight rod is inserted into the connecting shaft through the slot and then welded and fixed, which can prevent the straight rod from rotating freely on the connecting shaft and avoid affecting the tightening effect of the heat shrink rope, thereby ensuring the performance.

[0014] To further optimize the technical solution, both ends of the straight rod are provided with slide grooves, and connectors are slidably inserted in the slide grooves. The connectors are respectively fixedly connected to the two ends of the heat shrink rope and are restricted in the slide grooves by means of limiting pieces.

[0015] After passing around the first arc-shaped piece, the two ends of the heat shrink rope are inserted into the slide grooves at both ends of the straight rod with the help of a connecting head, so as to be assembled with the straight rod. The operation is simple. When the straight rod rotates the connecting shaft to make the heat shrink rope wrap around and shrink, the heat shrink rope pulls the connecting head, thereby preventing the connecting head from falling off from the slide groove. The use is stable and reliable.

[0016] To further optimize the technical solution, the limiter comprises connection caps threadedly connected to both ends of the straight rod.

[0017] The connecting caps threadedly connected at both ends of the straight rod block the slide grooves at both ends to prevent the connecting head from falling off from the slide groove, thereby ensuring the reliability of the use of the heat shrink rope.

[0018] To further optimize the technical solution, the outer arc wall of the first arc-shaped piece is provided with card slots along the length direction, the card slots respectively correspond to the positions and quantities of the heat shrinkable ropes, and the heat shrinkable ropes are all carded with the card slots.

[0019] When the heat shrink cord is passed around the first arc-shaped piece, it is inserted into the card slot on the first arc-shaped piece. After the heat shrink cord is tightened, the heat shrink cord is prevented from moving around and falling off, thereby improving the safety of use.

[0020] The beneficial effects of the utility model are:

[0021] 1. The rubber pad is attached to the pipeline through the first arc piece and the second arc piece. The two ends of the heat shrink rope are passed around the first arc piece and connected to the straight rod. The operator rotates the connecting shaft with the help of the straight rod to make the heat shrink rope wrap and shrink, so as to tighten the first arc piece and the second arc piece, ensure that the rubber pad fits tightly with the pipeline, ensure the reliability of pipeline plugging, and the heat in the pipeline is transferred to the heat shrink rope, so that it shrinks due to heat, further tightens the first arc piece and the second arc piece, and improves the sealing and plugging effect;

[0022] 2. When the connecting shaft is rotated by the straight rod, no additional tools are required, and the operation is simpler. The connecting shaft is installed with the second arc-shaped piece through a one-way bearing to rotate in one direction, so that after the heat shrink rope is wound and shrunk, the heat shrink rope is prevented from loosening, ensuring the reliability of use. The sleeve is arranged outside the connecting shaft, so that the heat shrink rope is wound along the sleeve to avoid interference with the one-way bearing, and the use is smooth and stable;

[0023] 3. When the heat shrink rope passes around the first arc-shaped piece, the heat shrink rope is stuck in the slot of the first arc-shaped piece. The slot constrains the heat shrink rope to prevent it from detaching from the first arc-shaped piece, thereby ensuring the reliability of leak plugging. The two ends of the heat shrink rope are connected to the sliding groove of the straight rod through the connecting head, making it easy to assemble with the straight rod. The connecting caps at both ends of the straight rod prevent the heat shrink rope from falling off, making it safer to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] Please see attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 The emergency plugging device for the heating pipe network comprises a first arc-shaped piece 1 and a second arc-shaped piece 2. The first arc-shaped piece 1 and the second arc-shaped piece 2 of suitable arc specifications are selected according to the diameter of the pipe to be plugged. The inner arc walls of the first arc-shaped piece 1 and the second arc-shaped piece 2 are fixedly attached with rubber pads 3. When plugging the pipe, the rubber pads 3 are attached to the pipe wall through the first arc-shaped piece 1 and the second arc-shaped piece 2. At least two heat shrink ropes 4 are arranged on the outer arc wall of the first arc-shaped piece 1 along the length direction. The outer arc wall of the first arc-shaped piece 1 is provided with a card slot 101 along the length direction. The card slot 101 corresponds to the position and number of the heat shrink rope 4 respectively. The heat shrink rope 4 can be prevented from falling off from the first arc-shaped piece 1 by being stuck in the card slot 101;

[0034] Please see attached Figure 2 And attached Figure 4-7At least two connecting shafts 5 are arranged on the outer arc wall of the second arc-shaped piece 2 along the length direction. The number and position of the connecting shafts 5 correspond to the heat shrink rope 4. A straight rod 6 is arranged on the free end of the connecting shaft 5. The middle part of the straight rod 6 is fixedly assembled with the connecting shaft 5. A slot 601 is arranged in the middle part of the straight rod 6. The slot 601 is plugged with the connecting shaft 5 and is welded and fixed to the connecting shaft 5. Both ends of the straight rod 6 are fixedly connected with the heat shrink rope 4. Both ends of the straight rod 6 are provided with a slide groove 602. The slide groove 602 can be a "T"-shaped structure. A connecting head 401 is slidably arranged in the slide groove 602. The connecting head 401 is fixedly connected to the two ends of the heat shrink rope 4 respectively, and is limited in the slide groove 602 by means of a limiting member. The limiting member includes a connecting cap 7 threadedly connected to the two ends of the straight rod 6, which can prevent the heat shrink rope 4 from falling off the straight rod 6 and improve the reliability of use.

[0035] Please see attached Figure 1 After the heat shrink rope 4 is assembled with the straight rod 6, the connecting shaft 5 is rotated by means of the straight rod 6 to drive the heat shrink rope 4 to wrap around the connecting shaft 5, so that the heat shrink rope 4 shrinks to tighten and fix the first arc-shaped sheet 1 and the second arc-shaped sheet 2 on the pipeline, so that the rubber pad 3 fits tightly on the pipeline, thereby plugging the leakage point of the pipeline, and when the pipeline conducts heat, the heat will be conducted to the heat shrink rope 4, causing it to shrink, so as to further tighten and fix the first arc-shaped sheet 1 and the second arc-shaped sheet 2, thereby improving the reliability of plugging;

[0036] Please see attached Figure 2 , Attachment Figure 5 The connecting shaft 5 is assembled on the second arc-shaped piece 2 in a unidirectional rotation manner. The outer wall of the connecting shaft 5 is sleeved with a one-way bearing 501. The one-way bearing 501 is fixedly installed with the second arc-shaped piece 2 by means of an assembly part. The assembly part includes a sleeve 201 arranged outside the connecting shaft 5. The sleeve 201 is fixedly installed with the second arc-shaped piece 2, and the one-way bearing 501 is sleeved and fixed with the sleeve 201. The connecting shaft 5 rotates unidirectionally along the one-way bearing 501, and the heat shrink rope 4 is wound tighter and tighter on the connecting shaft 5. In addition, the connecting shaft 5 cannot rotate in the opposite direction, so that the heat shrink rope 4 cannot be released and becomes loose. The operation is simple and reliable, and the first arc-shaped piece 1 and the second arc-shaped piece 2 do not need to be tightened with the help of additional tools. The use is flexible and efficient.

[0037] The working principle of the emergency plugging device for the heating pipe network is as follows: after the rubber pad 3 is attached to the leakage point of the pipeline through the first arc-shaped piece 1 and the second arc-shaped piece 2, the heat shrink rope 4 is taken and inserted into the card groove 101 of the first arc-shaped piece 1 respectively, and after the two ends of the rubber pad 3 pass through the first arc-shaped piece 1, they are plugged into the slide groove 602 on the straight rod 6 through the connecting head 401, and then the connecting cap 7 is threadedly connected to the straight rod 6 to prevent the heat shrink rope 4 from falling off the straight rod 6. Then, the operator rotates the connecting shaft 5 with the help of the straight rod 6 to make it rotate around the free end of the one-way bearing 501 in the sleeve 201, so as to wrap the heat shrink rope 4 around the sleeve. 201, so that the heat shrink rope 4 is tightened and shrunk, the first arc piece 1 and the second arc piece 2 are tightened, and the rubber pad 3 is closely attached to the pipeline, and the leaking point on the pipeline is blocked to ensure the blocking effect, and no additional tools are required, the operation is simple and efficient, and the one-way rotation of the connecting shaft 5 can prevent the heat shrink rope 4 from loosening, improve the firmness of the locking of the first arc piece 1 and the second arc piece 2, and when the pipeline is transmitting heat energy, the heat will be conducted to the heat shrink rope 4, so that the heat shrink rope 4 shrinks, and further tightens the first arc piece 1 and the second arc piece 2, so as to improve the firmness and reliability of the pipeline leak plugging;

[0038] After the emergency plugging is completed, the heat shrink rope 4 is cut so that it can be spread out and removed, thereby releasing the restriction on the first arc-shaped sheet 1 and the second arc-shaped sheet 2 so that they can be removed, and the first arc-shaped sheet 1 and the second arc-shaped sheet 2 and the rubber pad 3 are inspected and maintained so that they can be used again. The heat shrink rope 4 shrinks due to heat, so its performance decreases and it does not need to be reused, thereby reducing the cost of use.
