The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a boiler pressure vessel with a leak-proof structure, such as Figure 1-4 As shown, a boiler pressure vessel with a leak-proof structure includes: a boiler pressure vessel body 1, the boiler pressure vessel body 1 including an exhaust pipe 2; a connecting pipe 3 disposed on one side of the exhaust pipe 2, both the connecting pipe 3 and the exhaust pipe 2 being provided with flanges 4; a plurality of screws 5 disposed on the two flanges 4, the screws 5 being threaded with nuts 6; and a fixing mechanism disposed on the exhaust pipe 2 and the screws 5 for fixing the screws 5.

[0022] In this embodiment, when connecting the exhaust pipe 2 and the connecting pipe 3 on the boiler pressure vessel body 1, the two flanges 4 are connected and fixed with screws 5. A sealing gasket is placed between the two flanges 4. Then, the nut 6 is threaded onto the screw 5, thereby connecting and fixing the exhaust pipe 2 and the connecting pipe 3. After installation, the screw 5 is horizontally fixed by the fixing mechanism to prevent the screw 5 from coming loose, thus ensuring a tight connection between the two flanges 4 without gaps, thereby preventing gas leakage and improving the safety of the boiler pressure vessel body 1. The working principle of the boiler pressure vessel body 1 is existing technology and will not be elaborated here. Through the overall cooperation, the screws 5 on the flanges 4 can be effectively prevented from coming loose, ensuring a tight connection between the two flanges 4, thereby effectively preventing gas leakage from the boiler pressure vessel body 1 and improving the safety of the boiler pressure vessel body 1.

[0023] In a further preferred embodiment of the present invention, the fixing mechanism includes: a mounting plate 7 disposed on one side of the exhaust pipe 2; a lead screw 8 threadedly mounted on the mounting plate 7, one end of the lead screw 8 being fixedly mounted with a positioning block 9; and a positioning groove 10 formed on the screw 5, the positioning groove 10 and the positioning block 9 being adapted and connected.

[0024] In this embodiment, when using the fixing mechanism, the positioning block 9 is adjusted to one side of the positioning groove 10, and then the lead screw 8 is rotated to move the positioning block 9, so that the positioning block 9 and the positioning groove 10 are connected, and the screw 5 is fixed laterally to prevent the screw 5 from coming loose, thereby making the two flanges 4 tightly connected without gaps, thus preventing gas leakage and improving the safety of the boiler pressure vessel body 1.

[0025] In a further preferred embodiment of the present invention, the exhaust pipe 2 and the mounting plate 7 are provided with an adjustment mechanism for adjusting the usage position of the mounting plate 7. The adjustment mechanism includes: a support plate 11 fixedly installed on the exhaust pipe 2, and a mounting shaft 12 rotatably installed on the support plate 11 via a damping shaft; and a connecting plate 13 fixedly installed on the top of the mounting shaft 12, the connecting plate 13 and the mounting plate 7 being fixedly connected.

[0026] In this embodiment, when installing the screw 5, the opening of the positioning groove 10 should be kept away from the exhaust pipe 2. This is to facilitate the connection between the positioning block 9 and the positioning groove 10. During installation, the operator can adjust the positioning block 9 according to the actual needs. When it is necessary to connect the positioning block 9 and the positioning groove 10, the mounting shaft 12 needs to be rotated according to the position of the positioning groove 10, so that the position of the mounting plate 7 can be adjusted, thereby facilitating the adjustment of the positioning block 9 to one side of the positioning groove 10, thus facilitating the connection between the positioning block 9 and the positioning groove 10.

[0027] In a further preferred embodiment of this utility model, the mounting plate 7 is provided with a monitoring mechanism for monitoring the movement of the lead screw 8. The monitoring mechanism includes: a mounting shell 14 mounted on the mounting plate 7; a connecting rod 15 slidably mounted on the mounting shell 14, one end of the connecting rod 15 being fixedly mounted with a placement block 16, and the other end of the connecting rod 15 being fixedly mounted with an abutment block; a stop block 17 fixedly sleeved on the connecting rod 15, and a spring 18 sleeved on the connecting rod 15; an alarm 19 fixedly mounted on one side of the outer wall of the mounting shell 14, and a trigger button 20 is provided inside the mounting shell 14, the trigger button 20 being adapted to the alarm 19, and the trigger button 20 being located on one side of the abutment block.

[0028] In this embodiment, after connecting the positioning block 9 and the positioning groove 10, the operator can install the entire monitoring mechanism on the mounting plate 7. This facilitates the operation of the lead screw 8. After the entire monitoring mechanism is installed on the mounting plate 7, the placement block 16 is located on one side of the lead screw 8. If the lead screw 8 is displaced due to thread slippage, the lead screw 8 will contact the placement block 16. When the placement block 16 is compressed, it will drive the stop block 17 on the connecting rod 15 to move and compress the spring 18. At the same time, it will drive the abutment block to move. When the connecting rod 15 moves a certain distance, the abutment block will contact the trigger button 20, thereby activating the alarm 19. The alarm 19 will sound an alarm to remind the operator, so that the operator can perform maintenance operations in a timely manner. This effectively ensures that the screw 5 will not slip, ensures a tight connection between the two flanges 4 without gaps, and avoids gas leakage, thereby improving the safety of the boiler pressure vessel body 1.

[0029] In a further preferred embodiment of the present invention, the stop block 17 is rectangular, the stop block 17 is slidably connected to the inner wall of the mounting shell 14, and a base 21 is fixedly installed at the bottom of the boiler pressure vessel body 1. A moving mechanism for moving the boiler pressure vessel body 1 is provided on the base 21.

[0030] In this embodiment, by making the stop 17 rectangular, the connecting rod 15 can be prevented from rotating, thereby preventing the placement block 16 from rotating, thus ensuring that the placement block 16 is located on one side of the lead screw 8, and the moving mechanism facilitates the movement of the boiler pressure vessel body 1.

[0031] In a further preferred embodiment of the present invention, the moving mechanism includes: a telescopic rod 22 fixedly installed on the base 21, a placement plate 23 fixedly installed on the output shaft of the telescopic rod 22; and a moving wheel 24 installed at the bottom of the placement plate 23 for moving the boiler pressure vessel body 1.

[0032] In this embodiment, when the boiler pressure vessel body 1 needs to be used, the telescopic rod 22 is activated to drive the moving wheel 24 at the bottom of the placement plate 23 to move down and contact the ground, thereby facilitating the movement of the boiler pressure vessel body 1. When movement is not required, the moving wheel 24 is moved up and de-contacted with the ground, which can improve the stability of the boiler pressure vessel body 1 during use.

[0033] In a further preferred embodiment of this utility model, a sliding rod is fixedly installed on the base 21, and a slider is fixedly installed on the placement plate 23, with the slider and the sliding rod being slidably connected.

[0034] In this embodiment, the stability of the placement plate 23 during movement can be improved by the cooperation of the slider and the slide bar.

[0035] In summary, compared with related technologies, through overall cooperation, the screws 5 on the flange 4 can be effectively prevented from coming loose, ensuring a tight connection between the two flanges 4. This effectively prevents gas leakage from the boiler pressure vessel body 1 and improves the safety of the boiler pressure vessel body 1 in use.
