Flange 17; an expansion frame 112 is fixedly connected to the outer wall of the connecting flange 17; an expansion box 18 is fixedly connected to the top of the expansion frame 112; a connecting strip 19 is slidably connected to the middle of the expansion box 18; a transmission gear 110 is rotatably connected to the side wall of the expansion box 18; a closing ring 111 is slidably connected to the inner side of the expansion frame 112; the closing ring 111 is connected to the connecting strip 19; the end of the transmission gear 110 near the expansion box 18 meshes with the bottom of the connecting strip 19; a return spring 113 is fixedly connected to the end of the connecting strip 19 away from the first connecting pipe 1. The reset spring column 113 is interconnected with the expansion box 18. During operation, when the connecting flange 17 needs to be connected to the pipeline to be tested, the connecting bar 19 is driven to move towards the reset spring column 113 by rotating the transmission gear column 110. During the movement of the connecting bar 19, the closing ring 111 can be moved towards the flange to be connected. Finally, the closing ring 111 deforms, achieving the sealing of external impurities. The overall device reduces the occurrence of external impurities directly entering between the connecting flange 17 and the flange to be connected. The overall device reduces the occurrence of corrosion caused by rainwater contact between the bolts used to connect the flange 17 and the flange to be connected. It improves the stability of the connecting flange 17 during long-term operation. Through standardized and fixed device design, the overall device achieves rapid and reliable connection with the oil depot fire protection system, greatly simplifies the pressure test process, shortens the time of a single pressure test operation, and reduces the number of people and working hours required for pressure test operations, thus reducing labor input. Due to its reliable sealing design and standardized operating procedures, it greatly reduces the safety risks of the pressure test operation itself, such as high-pressure water splashing and connection detachment, ensuring personnel safety.

[0020] Furthermore, such as Figure 4As shown, a fixed side box 2 is fixedly connected to one side wall of the expansion box 18; the fixed side box 2 is sleeved on the outside of the transmission gear column 110; a gear ring 21 is fixedly connected to the outer wall of the transmission gear column 110; a connecting ring 22 is slidably connected to the inner side of the fixed side box 2; teeth 23 are rotatably connected to the side wall of the connecting ring 22; the teeth 23 mesh with the gear ring 21; multiple sets of elastic plates 24 are fixedly connected to the side wall of the connecting ring 22; the elastic plates 24 are connected to the teeth 23; multiple sets of locking blocks 25 are fixedly connected to the side wall of the connecting ring 22; the locking blocks 25 are in contact with the teeth 23; a connecting member 26 is provided inside the fixed side box 2; the connecting member 26 is connected to the connecting ring 22; the outer wall of the fixed side box 2 is provided with... The device includes a connecting plate 27, which is connected to the connecting member 26. During operation, the gear ring 21, teeth 23, elastic plate 24, and locking block 25 work together to ensure that the gear ring 21 can only move in one direction. This reduces the risk of the sealing ring 111 retracting when the connecting strip 19 and the sealing ring 111 seal the connected flange. The overall device improves the sealing effect and stability of the sealing ring 111. When it is necessary to operate the transmission gear column 110 to drive the sealing ring 111 to stop sealing the connected flange, the connecting plate 27 is operated to drive the connecting member 26 and the connecting ring 22 so that the teeth 23 no longer mesh with the gear ring 21. At this time, the operator can rotate the transmission gear column 110 at will.

[0021] Furthermore, such as Figure 1 As shown, a fixed post 3 is fixedly connected to the outside of the fire water connection pipe 16; a first magnetic ring 31 is fixedly connected to the outer wall of the fixed post 3; a closed sleeve post 33 is sleeved on the outside of the fixed post 3; a second magnetic plate 32 is fixedly connected to the end of the closed sleeve post 33; a connecting post 34 is fixedly connected to the end of the closed sleeve post 33 away from the fire water connection pipe 16; during operation, the first magnetic ring 31 and the second magnetic plate 32 attract each other due to magnetic force; the operator can operate the connecting post 34 to make the closed sleeve post 33 slide outside the fixed post 3, and finally the first magnetic ring 31 and the second magnetic plate 32 realize the installation of the closed sleeve post 33 outside the fixed post 3 due to magnetic force; the overall device reduces the occurrence of external impurities directly entering the inside of the fire water connection pipe 16; the overall device improves the ease of temporarily connecting the fire water connection pipe 16 after it has not been used for a long time.

[0022] Furthermore, such as Figure 2 As shown, a support column 4 is fixedly connected to one side wall of the first connecting pipe 1; a support ring 41 is fixedly connected to the outer side wall of the second connecting pipe 11; the support column 4 and the support ring 41 are connected to each other; during operation, the support column 4 and the support ring 41 cooperate with each other to support the middle part of the second connecting pipe 11, thereby reducing the load at the connection between the second connecting pipe 11 and the first connecting pipe 1, and improving the stability of the second connecting pipe 11 during long-term operation of the overall device.

[0023] Furthermore, such as Figure 4 As shown, a sealing flexible plate 5 is fixedly connected to the bottom of the expansion box 18; the sealing flexible plate 5 is connected to the outer wall of the sealing ring 111; during operation, as the sealing ring 111 moves, the sealing flexible plate 5 deforms accordingly, thereby achieving the effect of sealing external impurities and reducing the accumulation of impurities inside the expansion box 18, thus improving the cleanliness of the overall device.

[0024] Furthermore, such as Figure 4 As shown, a sealing plate 6 is fixed to the end of the connecting strip 19 away from the reset spring post 113. During operation, when the connecting strip 19 enters the inside of the expansion box 18, the sealing plate 6 fits against the side wall of the fire water pipe 16, thereby reducing the occurrence of external impurities entering the interior of the expansion box 18 through the connection between the expansion box 18 and the connecting strip 19. The overall device improves the cleanliness of the connection between the expansion box 18 and the transmission gear post 110 and the stability during long-term operation.

[0025] Furthermore, such as Figure 4 As shown, a connecting handle 7 is fixedly connected to the bottom of the connecting plate 27; during operation, the operator can directly operate the connecting plate 27 to move through the connecting handle 7, thereby improving the ease of operation of the connecting plate 27 and improving the overall work efficiency.

[0026] Working Principle: During operation, when the connecting flange 17 needs to be connected to the pipeline to be inspected, the transmission gear 110 is rotated, thereby driving the connecting bar 19 to move towards the return spring column 113. During this movement, the connecting bar 19 also drives the closing ring 111 towards the connected flange, ultimately deforming the closing ring 111 to seal off external impurities. The overall device reduces the likelihood of external impurities directly entering between the connecting flange 17 and the connected flange; it also reduces the risk of corrosion caused by rainwater contact with the bolts used to connect the flange 17 and the connected flange; it improves the stability of the connecting flange 17 during long-term operation; and through standardized and fixed device design, it achieves seamless integration with oil depot disinfection systems. The rapid and reliable connection of the anti-corrosion system significantly simplifies the pressure testing process, shortens the time of a single pressure test, and reduces the number of personnel and working hours required for pressure testing, thus reducing labor input. Due to its reliable sealing design and standardized operating procedures, it greatly reduces the safety risks inherent in pressure testing, such as high-pressure water splashing and connection detachment, ensuring personnel safety. During operation, the toothed ring 21, teeth 23, elastic plate 24, and locking block 25 work together to ensure that the toothed ring 21 can only move in one direction, thereby reducing the possibility of the sealing ring 111 retracting when the connecting strip 19 and the sealing ring 111 are sealing the connected flange. The overall device improves the sealing effect and stability of the sealing ring 111. When the transmission gear 110 needs to be operated to drive the sealing ring... When the closed loop 111 no longer seals the connected flange, the connecting plate 27 drives the connecting piece 26 and the connecting ring 22 so that the teeth 23 no longer mesh with the gear ring 21. At this time, the operator can rotate the transmission gear column 110 at will. During operation, the first magnetic ring 31 and the second magnetic plate 32 attract each other due to magnetic force. The operator can operate the connecting column 34 to make the closing sleeve column 33 slide outside the fixed column 3. Finally, the first magnetic ring 31 and the second magnetic plate 32 achieve the installation of the closing sleeve column 33 outside the fixed column 3 due to magnetic force. The overall device reduces the occurrence of external impurities directly entering the inside of the fire water connection pipe 16. The overall device improves the ease of temporarily connecting the fire water connection pipe 16 after it has not been used for a long time. During operation, the support column 4 and the support ring 41 cooperate to support the middle part of the second connecting pipe 11, thereby reducing the load at the connection between the second connecting pipe 11 and the first connecting pipe 1, and improving the stability of the second connecting pipe 11 during long-term operation. During operation, as the closing ring 111 moves, the sealing plate 5 deforms accordingly, thereby achieving the effect of sealing external impurities and reducing the accumulation of impurities inside the expansion box 18, thus improving the cleanliness of the overall device. During operation, when the connecting strip 19 enters the inside of the expansion box 18, the sealing plate 6 fits against the side wall of the fire water connection pipe 16, thereby reducing the possibility of external impurities entering the expansion box 18 through the connection between the expansion box 18 and the connecting strip 19.The overall device improves the cleanliness and stability of the connection between the expansion box 18 and the transmission gear 110 during long-term operation. During operation, the operator can directly move the connecting plate 27 via the connecting handle 7, thereby improving the ease of operation of the connecting plate 27 and increasing overall work efficiency.
