DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 A leakage prevention device for boiler production includes two protective tubes 1. The bottom ends of the two protective tubes 1 are connected by hinges. A connecting sleeve 2 is provided on one side of one of the protective tubes 1. A mounting tube 3 is provided on the surface of the connecting sleeve 2 by bolts. A mounting tube 4 is slidably connected inside the mounting tube 3. A leak detector 41 is provided at one end of the mounting tube 4. The leak detector 41 is an existing device. When water leaks, high-frequency noise will be generated in the surrounding area. The leak detector 41 receives and amplifies these noise signals. A transmission line 42 is provided inside the mounting tube 4. The transmission line 42 is electrically connected to the leak detector 41. An earphone 43 is provided at one end of the transmission line 42. Protective components 8 are provided on the surfaces of the two protective tubes 1. The protective component 8 can adapt to boiler components of different shapes and sizes, and can reduce the influence of external noise on detection.

[0023] The protective assembly 8 includes four fixed plates 81, four mounting plates 82 and four rubber plates 83. The four fixed plates 81 are respectively arranged at the two ends of the two protective tubes 1. The surface of the fixed plate 81 is provided with a mounting plate 82, and the interior of the mounting plate 82 is provided with a rubber plate 83. The surface of the rubber plate 83 is provided with a tightening groove 84, and the two rubber plates 83 on the same side correspond to each other. Since the rubber plate 83 is made of soft rubber material, it has excellent elasticity and softness, and can adapt to boiler components of different shapes and sizes through the tightening groove 84.

[0024] A connecting groove 100 is formed on the inner wall of one of the protective tubes 1 . The connecting groove 100 is connected to the interior of the connecting sleeve 2 . The leak detector 41 extends into the interior of the protective tube 1 through the connecting groove 100 .

[0025] A connecting plate 3001 is provided at one end of the mounting tube 3, and the connecting plate 3001 is an arc-shaped structure. A screw rod 3002 is threadedly connected to the middle of the connecting plate 3001, and a connecting block 3003 is provided at the top of the screw rod 3002. By screwing the screw rod 3002, the bottom end of the screw rod 3002 can contact the upper surface of the positioning rod 45, thereby limiting the movement of the mounting tube 4.

[0026] A positioning rod 45 is provided on the upper surface of the mounting tube 4, and a positioning groove matching the positioning rod 45 is provided on the inner wall of the connecting plate 3001. The positioning rod 45 is slidably connected to the positioning groove to provide guidance for the movement of the mounting tube 4 so that the mounting tube 4 and the leak detector 41 will not rotate.

[0027] A pull ring 44 is provided at one end of the installation tube 4 , and pull blocks are provided on both sides of the pull ring 44 , which can be used to pull the pull ring 44 to move conveniently, and the pull blocks are made of heat-insulating rubber material.

[0028] A fixing block 7 is provided at the top of the protective tube 1, and a handle 701 is provided on the top of the fixing block 7 to facilitate the adjustment of the opening and closing angle of the protective tube 1. Mutual connecting holes 702 are provided in the middle of the two fixing blocks 7. The two connecting holes 702 are fixedly connected by bolts, and the two fixing blocks 7 are fixed by the cooperation of the bolts.

[0029] When in use, since the bottom ends of the two protective tubes 1 are connected by a hinge, the opening and closing angles of the two protective tubes 1 are adjusted so that they are sleeved outside the flange of the boiler to be detected and the furnace tube, and the left and right positions of the two protective tubes 1 are adjusted so that the leak detector 41 is aligned with the connection between the boiler and the furnace tube. Since the rubber plate 83 is made of soft rubber material, it has excellent elasticity and softness, and can adapt to boiler components of different shapes and sizes through the tightening groove 84. After the two protective tubes 1 are adjusted to a closed state, the fixing block 7 is then fixed by bolts, so that the operator can easily complete the installation. The staff pushes the installation tube 4 forward through the cooperation of the pull block and the pull ring 44. During the movement of the installation tube 4, the transmission line 42 and the leak detector 41 are driven to move synchronously, so that the detection end of the leak detector 41 and the connection between the boiler are aligned. The leak detector 41 receives and amplifies these noise signals to improve the leak detection effect. The positioning rod 45 is slidably connected to the positioning groove on the inner wall of the connecting plate 3001 to provide guidance for the movement of the mounting pipe 4, so that the mounting pipe 4 and the leak detector 41 will not rotate. The leak detector 41 monitors the sound of water coming out of the detection part in real time. The leak detector 41 transmits the monitored information to the earphone 43 through the transmission line 42, so that the staff can judge the anti-leakage status of the boiler through the earphone 43, which has higher work efficiency. During the detection process, the protective tubes 1 on both sides can protect the staff and prevent the high-temperature water vapor from harming the staff. At the same time, the rubber plates 83 at both ends can form the protective tube 1 into a relatively closed space, which can reduce the impact of external noise on the detection.
