Description

Technical Field

[0001] The utility model relates to the technical field of waterproof casings, in particular to a waterproof and anti-corrosion casing for a thermal pipeline. Background Art

[0002] Sealing water-stopping sleeves are divided into rigid water-stopping sleeves and flexible water-stopping sleeves. In order to ensure the principle of reducing the number of holes opened after the building is completed, during the construction of the building, sealing water-stopping sleeves need to be pre-installed at the location where the thermal pipe needs to be installed. After the construction is completed, the pipe to be installed is passed through the sealing water-stopping sleeve to achieve the pipe installation. As the main pipe for urban heating, the thermal pipe needs good thermal insulation effect during the installation process to reduce heat consumption. Therefore, the thermal sealing water-stopping sleeve used for the thermal pipe needs better sealing performance to improve the thermal insulation effect compared with the ordinary water-stopping sleeve. Therefore, the flexible water-stopping sleeve is generally used for the water-stopping sleeve of the thermal pipe;

[0003] In order to facilitate the installation of the gland after the pre-embedded casing body, the screw rods used are mostly capless single-rod screw rods. When in use, first screw in a corresponding number of single-rod screw rods, and then insert the gland into the casing body accordingly, so that multiple single-rod screw rods pass through the through holes on the gland, and finally lock them with nuts. After the fixation is completed, the screw rod and nut are exposed to the air. When encountering rainy weather, the air humidity is high, the moisture will be absorbed by the wall, and gradually penetrate into the screw rod and nut, causing corrosion of the screw rod and nut, and reducing the service life of the screw rod and nut.

[0017] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0018] Please refer to Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of a thermal pipeline waterproof and anti-corrosion casing provided by the utility model; Figure 2 It is a schematic diagram of the exploded structure of the utility model; Figure 3 For the utility model Figure 2 The enlarged structural diagram of A in the middle includes: a waterproof sleeve 1, a flange 2 and a protective structure 3. The waterproof sleeve 1 is provided with a flange 2 at one end. The waterproof sleeve 1 and the outer surface of the flange 2 are provided with a protective structure 3. The protective structure 3 reduces the contact between the internal parts of the protective structure 3 and water and air, and reduces corrosion. The protective structure 3 includes a first fixing ring 4, a rotating shaft 5 and a second fixing ring 6. The rotating shaft 5 is provided between the first fixing ring 4 and the second fixing ring 6.

[0019] In the specific implementation process, Figure 1 , Figure 2 and Figure 3 As shown, water stop plates 7 are fixedly connected at both ends and the middle of the waterproof sleeve 1, and four groups of screw rods 8 are fixedly connected to the side surface of the water stop plate 7 at one end of the waterproof sleeve 1 close to the protective structure 3. The diameter of the end of the waterproof sleeve 1 close to the protective structure 3 is larger than the diameter of the other end of the waterproof sleeve 1, which is convenient for installing the structure.

[0020] Among them, the flange 2 is fixedly connected to a connecting pipe 9 on one side close to the waterproof sleeve 1, and the connecting pipe 9 is arranged inside the waterproof sleeve 1. Four groups of through holes are opened on the side surface of the flange 2. Four groups of screw rods 8 extend to the other side of the flange 2 through the four groups of through holes on the side surface of the flange 2 at one end away from the waterproof sleeve 1. Nuts 10 are sleeved on the outer surfaces of one end of the four groups of screw rods 8 passing through the four groups of through holes on the side surface of the flange 2. The through holes on one side of the flange 2 are aligned with the screw rods 8 and one end of the screw rods 8 is screwed into the nut 10.

[0021] Among them, a thermal pipe body 11 is arranged inside the connecting pipe 9, one end of the thermal pipe body 11 extends into the waterproof sleeve 1, and a rubber ring 12 is sleeved on the outer surface of one end of the thermal pipe body 11 extending into the waterproof sleeve 1. The end of the connecting pipe 9 away from the flange 2 is attached to the outer surface of the rubber ring 12, the flange 2 squeezes the connecting pipe 9, and the connecting pipe 9 squeezes the rubber ring 12. Since the diameter of one end of the waterproof sleeve 1 is larger than the diameter of the other end, the rubber ring 12 is squeezed on the inner wall of the waterproof sleeve 1, so that the rubber ring 12 squeezes and fills the gap between the thermal pipe body 11 and the waterproof sleeve 1, thereby fixing the thermal pipe body 11 on the inner wall of the waterproof sleeve 1.

[0022] Among them, the outer surfaces of the first fixing ring 4 and the second fixing ring 6 at one end away from the rotating shaft 5 are fixedly connected with a group of connecting blocks 13, and the inner walls of the first fixing ring 4 and the second fixing ring 6 are provided with two groups of grooves 16. The water stop plate 7 at the end of the waterproof sleeve 1 close to the protective structure 3 is arranged inside one group of grooves 16 on the inner walls of the first fixing ring 4 and the second fixing ring 6, and the flange 2 is arranged inside the other group of grooves 16 on the inner walls of the first fixing ring 4 and the second fixing ring 6. The grooves 16 increase the connection strength between the first fixing ring 4 and the second fixing ring 6 and the flange 2 and the water stop plate 7. Rubber pads 14 are arranged on the inner walls on both sides of the first fixing ring 4 and the second fixing ring 6. The rubber pad 14 on the inner wall of one side of the first fixing ring 4 and the second fixing ring 6 is attached to the side of the water stop plate 7 at one end of the waterproof sleeve 1 close to the protective structure 3, and the rubber pad 14 on the inner wall of the other side is attached to one end of the screw rod 8, and the rubber pad 14 enhances the sealing performance.

[0023] Among them, a threaded hole is opened on the side surface of the connecting block 13, and a bolt 15 is arranged inside the threaded hole. One end of the bolt 15 extends to the inside of the threaded hole on the side surface of another group of connecting blocks 13. The bolt 15 is threadedly connected to the threaded hole, which facilitates the connection of the two groups of connecting blocks 13.

[0024] The working principle provided by the utility model is as follows: the operator first sets a rubber ring 12 on one end of the heat pipe body 11, passes one end of the heat pipe body 11 through the flange 2 and the connecting pipe 9 into the interior of the waterproof casing 1, and at the same time aligns the through hole on one side of the flange 2 with the screw 8, screws one end of the screw 8 into the nut 10, and as the nut 10 is screwed in, the flange 2 squeezes the connecting pipe 9, and the connecting pipe 9 squeezes the rubber ring 12. Since the diameter of one end of the waterproof casing 1 is greater than the diameter of the other end, the rubber ring 12 is squeezed on the inner wall of the waterproof casing 1, so that the rubber ring 12 squeezes and fills the gap between the heat pipe body 11 and the waterproof casing 1, and then fixes the heat pipe body 11 on the inner wall of the waterproof casing 1, and at the same time the operator fixes the first fixing ring 4 and the second fixing ring 6 are sleeved on the water stop plate 7 and the outer surface of the flange 2, and the two groups of grooves 16 on the inner walls of the first fixing ring 4 and the second fixing ring 6 are respectively engaged with the water stop plate 7 and the outer surface of the flange 2. At the same time, the inner wall rubber pad 14 on one side of the first fixing ring 4 and the second fixing ring 6 is attached to the side of the water stop plate 7 at one end of the waterproof sleeve 1 close to the protective structure 3, and the inner wall rubber pad 14 on the other side is attached to one end of the screw rod 8. The operator closes the first fixing ring 4 and the second fixing ring 6 by rotating the shaft 5, and screws the bolts 15 into the threaded holes on the side surfaces of the two groups of connecting blocks 13, thereby completing the fixing of the protective structure 3, preventing liquid and air from contacting the screw rod 8 and the nut 10 for a long time, causing the screw rod 8 and the nut 10 to rust and be inconvenient to disassemble.
