The damaged paint layer of the fire riser during transportation is scraped off by the scraper to avoid water leakage or air leakage caused by poor contact between the sealing ring and the fire riser due to uneven paint layer. By scraping off the paint layer, close contact between the sealing ring and the fire riser can be ensured, the sealing effect can be improved, and leakage problems caused by uneven contact can be prevented. At the same time, the scraper can be driven from a horizontal state to a vertical state by folding the support rod, thereby scraping off the damaged paint layer on the contact side of the outer surface of the fire riser and the sealing ring 3, so that the clamp can press the sealing ring more evenly and fully, avoiding the damaged paint layer from causing an uneven surface when the sealing ring contacts the fire riser, affecting the sealing effect.

The inner wall of the clamp 31 is integrally formed with two inclined flanges for inserting into the slot 4 on the hollow extension seat 13 and the slot 4 on the fire riser 2 respectively, and the two inclined flanges are both arranged in coordination with the inclined surface, and the sealing ring 33 is located between the two inclined flanges.

[0023] The end surface of the hollow extension seat 13 away from the end of the bracket 1 is provided with a plurality of openings 15 at intervals, and the plurality of openings 15 are all located between the sealing ring 14 and the hollow extension end 11; the hollow extension seat 13 is provided with an annular groove 16 connected to the opening 15; the bracket 1 is provided with a drainage groove 17 connected to the annular groove 16; the lower end surface of the bracket 1 is connected to a water storage bottle 18 by threads, and the outlet of the drainage groove 17 is connected to the water storage bottle 18.

[0024] By adopting the above technical solution, a sealing ring 33 is first sleeved on the outside of the fire riser 2 below, and then the hollow extension end 11 at the lower end of the bracket 1 is inserted into the inside of the fire riser 2 below, so that the sealing ring 2 14 on the hollow extension seat 13 at the lower end of the bracket 1 can be fitted with the upper end of the fire riser 2 below, and then the sealing ring 33 outside the fire riser 2 is moved to move the sealing ring 333 to the connection between the sealing ring 2 14 and the hollow extension seat 13, and then two hoops 31 are used to wrap around the outside of the sealing ring 33, and the two hoops 31 are locked and connected by the bolt locking member 32, and the sealing ring 33 is pressed by the two hoops 31. Tighten the connection between the hollow extension seat 13 and the fire riser 2, and then fix the bracket 1 to the wall with expansion bolts; first, sleeve another sealing ring 33 on the outside of the upper fire riser 2, and then sleeve the upper fire riser 2 on the outside of the hollow extension end 11 of the upper end of the bracket 1, so that the sealing ring 2 14 on the hollow extension seat 13 at the upper end of the bracket 1 can fit with the lower end of the upper fire riser 2, move the sealing ring 33 on the outside of the upper fire riser 2 to the connection between the sealing ring 2 14 and the hollow extension seat 13, and then use two clamps 31 to wrap around the outside of the sealing ring 33, and tighten the two clamps 31 with the bolt locking parts 32.

[0025] like Figure 5-7 and Fig.13As shown, the two hollow extension seats 13 are connected to a joint surface smoothing processing unit 5 on one side away from the bracket 1, and the joint surface smoothing processing unit 5 includes a height adjustment component 56 connected to the inside of the hollow extension seat 13, a disk body 51 fixedly arranged at one end of the height adjustment component 56 away from the hollow extension seat 13, a turntable 52 rotatably connected to the side of the disk body 51 away from the height adjustment component 56, and a paint surface smoothing component 53 connected to the side of the turntable 52 away from the disk body 51, the paint surface smoothing component 53 includes a movable groove 531 opened in the turntable 52, a movable seat 532 slidably connected to the inner wall of the movable groove 531, a screw rod 533 connected to the inside of the turntable 52 by threads, and a scraper 536 connected to the middle part of the upper end surface of the movable seat 532, the screw rod 533 is rotatably connected to the movable seat 532, and the end of the screw rod 533 close to the movable seat 532 is located inside the movable groove 531.

[0026] One end of the scraper 536 is rotatably connected to the upper end surface of the movable seat 1 532, and a movable groove 2 534 is provided on the upper end surface of the movable seat 1 532, and two folding support rods 535 are arranged inside the movable groove 2 534, and one end of the two folding support rods 535 are rotatably connected to the inner walls on both sides of the movable groove 2 534, and the other support ends of the two folding support rods 535 are rotatably connected to the side walls on both sides of the scraper 536.

[0027] The height adjustment assembly 56 includes two guide columns 561 symmetrically fixedly connected to the side of the disk body 51 close to the hollow extension seat 13, two slots 563 symmetrically opened inside the hollow extension seat 13 to match the guide columns 561, and positioning holes 562 spaced apart on the guide columns 561. Sockets are symmetrically opened on the side wall of the hollow extension seat 13 to match the positioning holes 562, and the sockets are connected to the slots 563. There are two sockets, and a pin 564 is inserted in the socket, and the pin 564 can be set in the socket and the positioning hole 562.

[0028] By adopting the above technical solution, before the hollow extension end 11 at the lower end of the bracket 1 is inserted into the lower fire riser 2 and the sealing ring 14 on the hollow extension end 11 at the lower end of the bracket 1 contacts the lower fire riser 2, and before the hollow extension end 11 at the upper end of the bracket 1 is inserted into the upper fire riser 2 and the sealing ring 14 on the hollow extension end 11 at the upper end of the bracket 1 contacts the upper fire riser 2, the pin 564 is pulled out from the positioning hole 562 and the socket, so that the guide column 561 can move in the slot 563, so as to adjust the distance between the disk body 51 and the hollow extension end 11, so that it is convenient for the disk body 51 to move and approach the adjacent fire riser 2. After the adjustment is completed, the pin 564 is inserted into the positioning hole 562 and the socket to complete the positioning of the guide column 561 and the disk body 51, and then the screw rod 1 533 is rotated to drive the movable seat 1 532 to move in the movable groove 1 531, so that The scraper 536 can contact one side of the adjacent fire riser 2. When the scraper 536 is in a horizontal state, the scraper 536 can first contact the opposite side of the fire riser 2 and the sealing ring 14. When the scraper 536 is rotated and changed from a horizontal state to a vertical state, the scraper 536 will drive the folding support rod 535 to unfold. The scraper 536 in the vertical state can be supported by the folding support rod 535. The scraper 536 in the vertical state can contact the outer surface of the fire riser 2. When the scraper 536 is in a vertical or horizontal state, the turntable 52 is manually rotated so that the turntable 52 can rotate on one side of the adjacent disk body 51. The rotation of the turntable 52 drives the scraper 536 to rotate. The damaged paint layer of the fire riser 2 during transportation is scraped off by the scraper 536 to avoid the uneven paint layer causing poor contact between the sealing ring and the fire riser 2 to cause water leakage or air leakage. If the paint layer is not scraped off, the sealing ring may not be able to evenly fit the surface of the fire riser 2, resulting in a poor seal, thereby creating the risk of water or air leakage. After scraping off the damaged paint layer, the sealing ring can better contact the metal surface, ensuring the sealing effect and preventing leakage problems caused by uneven contact, so that the clamp 31 can more evenly and fully press the sealing ring 3 33, avoiding the damaged paint layer that may cause an uneven surface when the sealing ring contacts the fire riser 2, affecting the sealing effect. After the uneven paint layer on the outer surface of the fire riser 2 is scraped off, the screw 1 533 is rotated to reset the scraper 536, and the pin 564 is pulled out. After the disc 51 is reset and contacts the hollow extension seat 13, the pin 564 is inserted into the positioning hole 562 and the jack to complete the positioning of the guide column 561 and the disc 51, and then the fire riser 2 is contacted with the sealing ring 2 14.

[0029] like Figure 5 and Figure 8-11As shown, a paint layer loosening processing component 54 is connected to the side of the two turntables 52 away from the disk body 51, and the paint layer loosening processing component 54 includes a movable groove three 541 opened on the side of the turntable 52 away from the disk body 51, a movable seat two 543 slidably connected to the inner wall of the movable groove three 541, a screw rod two 542 connected to the inside of the turntable 52 by threads, a movable groove five 548 opened in the movable seat two 543, a movable seat three 549 connected to the inside of the movable groove five 548, a vertical plate 544 fixedly connected to the side of the movable seat three 549 away from the turntable 52, a wire brush one 545 and a serrated flange 546 fixedly connected to the side of the vertical plate 544 away from the screw rod two 542, the screw rod two 542 is rotatably connected to the movable seat two 543, and the end of the screw rod two 542 close to the movable seat two 543 is located inside the movable groove three 541.

[0030] The two disk bodies 51 are fixedly connected with a plurality of inclined top flanges 511 at intervals on one side away from the hollow extension seat 13. The two movable seats 543 are provided with movable grooves 547 connected with the movable grooves 548, and the movable grooves 547 are located below the movable grooves 548. The movable grooves 547 are connected with reciprocating components 6. The reciprocating components 6 include two guide rods 62 fixedly connected to the inner walls of the movable grooves 547 on both sides, and a movable sleeve on the outer surface of the guide rods 62. The movable plate 61, two springs 63 respectively sleeved on the outer surfaces of the two guide rods 62, and the inclined top flange 2 64 fixedly connected to the movable plate 61 away from the movable groove 5 548, the two ends of the spring 63 are respectively connected to the inner wall of the movable groove 4 547 and the movable plate 61, the movable seat 3 549 is slidably connected in the movable groove 5 548, the end of the movable seat 3 549 away from the vertical plate 544 extends into the movable groove 4 547, and the end of the movable seat 3 549 away from the vertical plate 544 is fixedly connected to the movable plate 61.

[0031] By adopting the above technical solution, when the adjustment of the docking surface leveling processing unit 5 is completed, the scraper 536 is in a vertical state and contacts one side of the fire riser 2. Before rotating the turntable 52, the screw rod 2 542 is rotated to make the movable seat 2 543 move in the movable groove 3 541, and the inclined top flange 2 64 can enter between the two adjacent inclined top flanges 1 511. At the same time, the wire brush 1 545 can contact the outer surface of the fire riser 2. The rotating turntable 52 drives the movable seat 2 543 and the vertical plate 544 to rotate, and the inclined top flange 2 64 can contact the inclined top flange 1 511. The inclined top flange 1 511 can push the inclined top flange 2 64 in the direction of the spring 63, so that the movable plate 61 moves inside the movable groove 4 547 and then drives the movable plate 61 to move. The seat three 549 moves. The movement of the movable seat three 549 can drive the vertical plate 544 and the wire brush 1 545 to move vertically up and down, thereby increasing the contact frequency and pressure between the wire brush 1 545 and the paint layer, so that the bristles of the wire brush 1 545 can more effectively cut into the paint layer, especially for the harder or more strongly attached paint layer, so as to better peel off the surface paint, cover a larger range of the surface, produce a more uniform scraping effect, and help remove the loose parts and aged paint layers on the paint surface, making these weak paints easier to scrape off, and making the subsequent contact between the scraper 536 and the paint layer smoother, avoiding the scraper 536 from getting stuck or sliding unevenly, reducing the burden on the scraper 536, and thus improving the efficiency of subsequent scraping.

[0035] Working principle and process: First, a sealing ring 33 is put on the outside of the fire riser 2 below, and then the hollow extension end 11 at the lower end of the bracket 1 is inserted into the interior of the fire riser 2 below. Before the sealing ring 214 on the hollow extension end 11 at the lower end of the bracket 1 contacts the fire riser 2 below, the screw rod 1533 is rotated to drive the movable seat 1532 to move in the movable groove 1531, and then the pin 564 is pulled out from the positioning hole 562 and the socket to move the disc 51 and approach the adjacent fire riser 2 until the scraper 536 can contact one side of the adjacent fire riser 2. When the scraper 536 is in a horizontal state, the scraper 536 can first contact the fire riser 2 with the relative position of the sealing ring 214. The rotating disk 52 rotates to drive the scraper 536 to rotate, and the wire brush 2 8 on one side of the movable seat 1 532 can pre-clean the uneven paint layer on the contact side of the fire riser 2 and the sealing ring 2 14. After pre-cleaning, the scraper 536 scrapes off the paint layer on one side of the fire riser 2 after pre-cleaning. At the same time, the grindstone 7 on one side of the movable seat 1 532 can grind the one side of the fire riser 2 scraped by the scraper 536; then rotate the scraper 536 and change the scraper 536 from horizontal to vertical, the folding support rod 535 can support the scraper 536 in the vertical state, and rotate the screw rod 2 542 to make the movable seat 2 543 move in the movable groove 3 541.
