Description

Technical Field

[0001] This utility model relates to the field of thermal insulation construction technology, and more specifically, to a waterproof sealing structure for the joint of a thermal insulation pipe. Background Technology

[0002] Thermal insulation pipe is short for heat-insulated pipeline. It is used to transport liquids, gases and other media, thereby reducing environmental pollution and the greenhouse effect. It consists of a rigid polyurethane foam insulation layer tightly bonded to the outer skin of the steel pipe, which isolates the penetration of air and water and provides good corrosion protection. At the same time, its foam pores are all closed, and its water absorption is very small. The high-density polyethylene shell and fiberglass shell have good corrosion resistance, insulation and mechanical properties.

[0003] A search revealed that the prior art discloses a sleeve joint tightening clamp for on-site insulation construction of insulated pipes, with patent publication number CN216692691U. The specification states that: by tightening the nuts, two arc-shaped plates are connected, and the internal force is increased to lock the connection, thereby increasing the contact surface. The screws apply mechanical force, greatly increasing the locking force, which allows the electrothermal fusion sleeve to be better fused and welded to the mother pipes at both ends, resulting in a better sealing effect.

[0004] However, in actual use, since the insulation pipe is buried underground, when maintaining or replacing the insulation pipe, workers need to enter the excavated pit and use screwdrivers and other tools to tighten the screws and nuts. Because the soil inside the hole is soft and damp, it is inconvenient for workers to move around, resulting in low efficiency in maintaining and replacing the sealing structure. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a waterproof sealing structure for the joint of a thermal insulation pipe, so as to solve the problem that the workers' movement is inconvenient due to the soft and damp soil inside the hole in the prior art, which leads to the low efficiency of maintenance and replacement of the sealing structure.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a waterproof sealing structure for the joint of an insulated pipe, comprising an arc-shaped plate one, a connecting block fixedly connected to the top of the arc-shaped plate one, an arc-shaped plate two slidably connected to the outside of the connecting block, the arc-shaped plate one and the arc-shaped plate two fitting together, two slots are opened on the left and right sides of the inside of the arc-shaped plate two, a locking block is engaged inside the slot, the locking block passes through the connecting block and is slidably connected inside the arc-shaped plate two, and a blocking block is hinged to the front and rear sides of the arc-shaped plate two.

[0007] The arc-shaped plate has multiple mounting slots inside. The end of the card block away from the slot is fixedly connected to a mounting plate. The end of the mounting plate away from the card block is fixedly connected to a pull rope. An elastic element is sleeved on the outside of the pull rope. A rotating rod is fixedly connected to the side of the pull rope away from the mounting plate.

[0008] In this configuration, a turntable is fixedly connected to the opposite side of each of the two rotating rods. A limit groove is formed on the side of each turntable away from the rotating rod. A limit block is inserted into the inside of the limit groove. A placement groove is formed on the adjacent side of each of the two blocking blocks. The limit block is fixedly connected to the inner wall of the placement groove.

[0009] The arc-shaped plate has slots on both the front and rear sides, and two protrusions are fixedly connected inside the slots. The plug block has inserts fixedly connected to both the left and right sides, and two grooves are formed on the inner side of the inserts.

[0010] The card block is slidably connected inside the mounting groove, the mounting plate is slidably connected inside the mounting groove, and the pull rope is slidably connected inside the mounting groove.

[0011] The rotating rod is rotatably connected inside the arc-shaped plate, one end of the elastic element is fixedly connected to the inner wall of the mounting groove, and the other end of the elastic element is fixedly connected to the mounting plate.

[0012] The insert is slidably connected inside the arc-shaped plate, and is inserted into the slot. The protrusion fits into the groove at the corresponding position.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In the above solution, the two arc-shaped plates are clamped together by using a clamping block and the clamping block is used to limit the clamping block, so that the clamping of the arc-shaped plates is relatively stable. Thus, while ensuring the installation stability of the arc-shaped plates, the maintenance and replacement efficiency of the insulation pipe is high, so as not to affect the construction progress, and the movement of workers is more convenient, thereby improving the construction safety.

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a waterproof sealing structure for the joint of an insulated pipe, including an arc-shaped plate 1, a connecting block 3 fixedly connected to the top of the arc-shaped plate 1, and an arc-shaped plate 2 slidably connected to the outside of the connecting block 3. The arc-shaped plate 1 and the arc-shaped plate 2 are in contact with each other. With the cooperation of the arc-shaped plate 1 and the arc-shaped plate 2, the joint of the pipe can be sealed and waterproofed. Two slots 4 are opened on the left and right sides inside the arc-shaped plate 2. A locking block 5 is locked inside the slot 4. The locking block 5 passes through the connecting block 3 and is slidably connected inside the arc-shaped plate 2, so that the connecting block 3 can be limited, thereby making the arc-shaped plate 1 and the arc-shaped plate 2 stably connected. A blocking block 14 is hinged on the front and rear sides of the arc-shaped plate 2. The blocking block 14 is used to block the notch on the arc-shaped plate 2, so that the locking block 5 can be stably installed.

[0025] When it is necessary to install the arc plate 1 and the arc plate 2, by fitting the arc plate 1 and the arc plate 2 together, the connecting block 3 can be inserted into the interior of the arc plate 2. Then, the left and right locking blocks 5 are moved to the opposite side, so that the locking blocks 5 can pass through the interior of the connecting block 3 and the locking groove 4 and engage, thereby limiting the locking blocks 5 and making the arc plate 1 and the arc plate 2 stably connected.

[0026] Example 2: Based on Example 1, to facilitate the pulling of the locking block 5, the interior of the arc-shaped plate 2 is provided with multiple mounting slots 6. The locking block 5 is slidably connected to the interior of the mounting slots 6, which provide space for the locking block 5 to move. A mounting piece 7 is fixedly connected to the end of the locking block 5 away from the slot 4. The mounting piece 7 is slidably connected to the interior of the mounting slot 6, which limits the mounting piece 7, preventing it from shifting during sliding. A pull rope 8 is fixedly connected to the end of the mounting piece 7 away from the locking block 5, and the pull rope 8 is slidably connected to the mounting piece 7. Inside the mounting groove 6, the mounting groove 6 limits the pull rope 8, allowing the pull rope 8 to slide smoothly. An elastic element 9 is sleeved on the outside of the pull rope 8. One end of the elastic element 9 is fixedly connected to the inner wall of the mounting groove 6, and the other end of the elastic element 9 is fixedly connected to the mounting plate 7. A rotating rod 10 is fixedly connected to the side of the pull rope 8 away from the mounting plate 7. The rotating rod 10 is used to wind one end of the pull rope 8. The rotating rod 10 is rotatably connected inside the arc plate 2. The arc plate 2 limits the rotating rod 10, allowing the rotating rod 10 to rotate smoothly.

[0027] When the locking block 5 needs to be pulled, the rotating rod 10 is rotated so that one end of the pull rope 8 is wound around it, and the other end of the pull rope 8 pulls the mounting plate 7 to compress the elastic element 9 and cause deformation. This allows the mounting plate 7 to pull the locking block 5 into the interior of the mounting groove 6. Conversely, by releasing the rotating rod 10, the elastic element 9 is reset, which pushes the mounting plate 7 to move outward, allowing the locking block 5 to pass through the connecting block 3 and engage with the interior of the locking groove 4.

[0028] Example 3: Based on Example 2, in order to limit the rotation rod 10, a turntable 11 is fixedly connected to the opposite side of the two rotation rods 10. A limit groove 12 is opened on the side of the turntable 11 away from the rotation rod 10. A limit block 13 is inserted into the inside of the limit groove 12. The limit block 13 is used to limit the rotation rod 10. A placement groove 15 is opened on the adjacent side of the two blocking blocks 14. The limit block 13 is fixedly connected to the inner wall of the placement groove 15. The placement groove 15 provides installation space for the limit block 13.

[0029] When the blocking block 14 is closed, the blocking block 14 can push the limiting block 13 into the interior of the limiting groove 12, so that the turntable 11 can be limited, and thus the turntable 11 will not rotate when not in use.

[0030] Example 4: Based on Example 3, in order to improve the stability of the blocking block 14 after closure, slots 16 are provided on both the front and rear sides of the arc plate 2. Two protrusions 17 are fixedly connected inside the slots 16. Inserts 18 are fixedly connected on both the left and right sides of the blocking block 14. The inserts 18 are slidably connected inside the arc plate 2, so that the arc plate 2 can squeeze the inserts 18 to deform. The inserts 18 are inserted into the slots 16, so that the blocking block 14 can be limited. Two grooves 19 are provided on the inner side of the inserts 18. The protrusions 17 fit into the grooves 19 at the corresponding positions, so that the connection stability between the inserts 18 and the slots 16 is higher.

[0031] When the blocking block 14 is closed, the insert block 18 can slide inside the arc plate 2, so that the insert block 18 can be squeezed and deformed. Then, when the insert block 18 is completely closed, the insert block 18 can enter the interior of the slot 16, so that the insert block 18 can engage with the slot 16, and the protrusion 17 can fit into the interior of the corresponding groove 19, thereby making the stability of the blocking block 14 after it is closed higher.

[0032] The working process of this utility model is as follows:

[0033] When it is necessary to install arc plate 1 and arc plate 2, by rotating the rotating rod 10, one end of the pull rope 8 is wound around the rotating rod 10, so that the other end of the pull rope 8 pulls the mounting piece 7 to compress the elastic element 9 and deform it. This causes the mounting piece 7 to pull the locking block 5 into the interior of the mounting groove 6, thereby bringing arc plate 1 and arc plate 2 into contact, allowing the connecting block 3 to be inserted into the interior of arc plate 2. Then, by releasing the rotating rod 10, the elastic element 9 is reset, which pushes the mounting piece 7 outward, allowing the locking block 5 to penetrate the interior of the connecting block 3 and the locking groove 4 and engage. This limits the locking block 5, thus stably connecting arc plate 1 and arc plate 2. Then, the blocking block 14 is closed. 4. The limiting block 13 is pushed into the limiting groove 12, so that the turntable 11 is limited and will not rotate when not in use. At the same time, the insert block 18 slides inside the arc plate 2, so that the insert block 18 is squeezed and deformed. When the insert block 18 is completely closed, the insert block 18 enters the slot 16, so that the insert block 18 engages with the slot 16, and the protrusion 17 fits into the corresponding groove 19. This makes the stability of the blocking block 14 after closing higher, so that the arc plate 1 and the arc plate 2 can be installed stably and disassembled easily. This makes the maintenance and replacement efficiency of the insulation pipe higher, so as not to affect the construction progress, and makes it easier for workers to move, thus improving the construction safety.
