[0033] The embodiment of the present application provides a flue gas emission monitoring device for a gas boiler. As Figure 1 shown, the flue gas emission monitoring device for the gas boiler is fixed to the wall 1. The monitoring device may include a fixed cylinder 2, a mounting post 3, a locking assembly, a sensor 4, an operation assembly, a positioning assembly, a sealing assembly, and a cleaning assembly.

[0034] Among them, the fixed cylinder 2 is fixedly installed on the wall 1 and passes through the wall 1. The fixed cylinder 2 is fixed to the wall 1, so as to install other components in the fixed cylinder 2.

[0035] The mounting post 3 is slidably installed in the fixed cylinder 2. The mounting post 3 can slide in the fixed cylinder 2, so as to achieve a detachable connection.

[0036] Please refer to Figure 5 and Figure 6Refer to the following. The locking component is arranged between the fixed cylinder 2 and the mounting post 3. The locking component can fix the relative positions of the mounting post 3 and the fixed cylinder 2 to install the mounting post 3, or release the locking of the mounting post 3 and the fixed cylinder 2 to disassemble the mounting cylinder 3.

[0037] The sensor 4 is fixed to one end of the mounting post 3 extending into the wall 1 and can extend into the exhaust duct along with the mounting post 3. Sensing devices such as flue gas sampling sensors and temperature sensors can be assembled for monitoring flue gas.

[0038] Please refer to Figure 7 and Figure 8 Refer to the following. The operating component is arranged at the other end of the mounting post 3 and can control the state of the locking component to achieve a quick conversion between the locked state and the unlocked state.

[0039] Please refer to Figures 3 - 5 Refer to the following. The positioning component is arranged between the fixed cylinder 2 and the mounting post 3. The positioning component can contact the fixed cylinder 2 prior to the sensor 4, thereby protecting the sensor 4 from being damaged due to accidental contact.

[0040] Please refer to Figure 2 and Figure 8 Refer to the following. The sealing component is arranged at one end of the fixed cylinder 2 and can automatically seal after the sensor 4 is disassembled, playing a role in isolating the flue gas and protecting the safety of the operators.

[0041] Such as Figure 9 shown, the cleaning component is arranged inside the fixed cylinder 2 and can automatically clean the sensor 4 when installing and disassembling the sensor 4, wiping off the soot to ensure the normal operation of the sensor 4.

[0042] Specifically, slide the mounting post 3 into the fixed cylinder 2. Through the cooperation of the operating component and the locking component, the quick installation and disassembly of the sensor 4 and the fixed cylinder 2 can be achieved. Then, through the positioning component, it can be ensured that the positioning component is connected prior to the fixed cylinder 2 during installation to protect the sensor 4. Secondly, through the sealing component, the opening of the fixed cylinder 2 in the chimney can be sealed when the sensor 4 is removed, preventing the flue gas from discharging from the fixed cylinder 2 and scalding the staff. Finally, through the cleaning component, the soot on the surface of the sensor 4 can be automatically removed when the sensor 4 is taken out to ensure the cleanliness of the sensor 4. Through the cooperation of the above structures, the components such as the sensor 4 can be installed and disassembled quickly and conveniently, which can not only reduce the working difficulty during maintenance, but also better protect the sensor 4 during disassembly and assembly to avoid damage to the sensor 4.

[0043] Please continue to refer to Figure 3 、 Figure 5 and Figure 6Referring thereto, in an exemplary embodiment, the locking assembly may include a lock hole 21, a chute 34, a lock tooth 6, and a driving mechanism. Among them, a plurality of lock holes 21 are provided and evenly opened on the inner side wall of the fixed cylinder 2. The chute 34 is opened on the outer side wall of the mounting post 3 and corresponds to the position of the lock hole 21. The lock tooth 6 is slidably installed in the chute 34. The driving mechanism is arranged in the mounting post 3 and is adapted to the lock tooth 6.

[0044] Specifically, first, the mounting post 3 is inserted into the fixed cylinder 2. The driving mechanism is driven by the operating component to drive the lock tooth 6 to slide into or out of the lock hole 21 along the chute 34, so as to achieve installation and fixation and quick disassembly. No additional auxiliary tools are required, and the staff can quickly and simply disassemble and assemble.

[0045] Furthermore, the driving mechanism may include a mounting groove 33, a rotating member 62, a second spring 61, and a spherical surface 63. Among them, the mounting groove 33 is opened inside the mounting post 3 and corresponds to the position of the chute 34. The rotating member 62 is rotatably installed in the mounting groove 33 and is provided with a protruding portion corresponding to the lock tooth 6. The second spring 61 is sleeved on the lock tooth 6, and both ends of the second spring 61 are fixedly connected to the lock tooth 6 and the chute 34 respectively. The spherical surface 63 is arranged at one end of the lock tooth 6 located inside the mounting post 3 and is adapted to the protruding portion.

[0046] Specifically, the rotating member 62 is driven to rotate in the mounting groove 33 by the operating component. When the rotating member 62 rotates, its protruding portion will push out the lock tooth 6. Through the cooperation of the spherical surface 63 and the protruding portion, the lock tooth 6 slides out along the chute 34 and is inserted into the lock hole 21 to achieve installation and locking. When unlocking, the rotating member 62 is rotated in the opposite direction, and the protruding portion is offset. Under the action of the second spring 61, the lock tooth 6 rebounds into the mounting post 3 to achieve unlocking. The rotating member 62 can make multiple lock teeth 6 move synchronously, ensuring that the mounting post will not shift after installation and making the installation more stable and firm.

[0047] Please continue to refer to Figure 7 and Figure 8 Referring thereto, in an exemplary embodiment, the operating component may include an operating disk 5, a through hole 51, a jack 32, a handle 52, a movable rod 53, and a first spring 54. Among them, the operating disk 5 is rotatably installed at one end of the mounting post 3, and the operating disk 5 is fixedly connected to the rotating member 62 through a connecting rod. Two through holes 51 are provided and symmetrically opened on the operating disk 5. Four jacks 32 are provided and symmetrically opened at one end of the mounting post 3. The four jacks 32 are divided into two groups in pairs, and one group of jacks 32 corresponds to the position of the through hole 51. The handle 52 is fixedly installed on the operating disk 5. The movable rod 53 is slidably installed in the through hole 51 and is slidably connected to the handle 52. A plurality of first springs 54 are fixedly installed between the outer surface walls of the movable rod 53 and the handle 52 opposite to each other.

[0048] Specifically, by holding the handle 52 and squeezing the movable rod 53 at the same time, the first spring 54 is compressed. The movable rod 53 slides along the through hole 51 and slides out of the jack 32. At this time, the operation disc 5 can be rotated, and the rotating member 62 is driven to rotate to control the locking teeth 6. When the rotation reaches a fixed angle to complete the locking or unlocking action, the movable rod 53 is released. Under the action of the first spring 54, the movable rod 53 slides and inserts into the jack 32 to lock the operation disc 5. When the sensor 4 needs to be disassembled and assembled, only need to hold the handle 52 and the movable rod 53, and rotate the operation disc 5 to pull out the mounting post 3, which is simple and fast.

[0049] Please continue to refer to Figure 4 and Figure 5 The positioning assembly can include positioning holes 22, mounting rings 31 and telescopic rods 7. Among them, two positioning holes 22 are provided, symmetrically opened on the fixed cylinder 2. The mounting ring 31 is fixedly sleeved on the mounting post 3. Two telescopic rods 7 are provided, symmetrically and fixedly installed on the mounting ring 31, and are adapted to the positioning holes 22.

[0050] Specifically, during installation, the telescopic rod 7 is first aligned with the positioning hole 22. The symmetrically arranged positioning holes 22 can ensure that the mounting post 3 and the sensor 4 will not shift. When the telescopic rod 7 reaches the bottom of the positioning hole 22, it begins to shorten, so as to ensure a sufficient long stroke and effectively protect the sensor 4 with requirements for the distance extending into the pipeline.

[0051] Further, the telescopic rod 7 can include a sleeve 71, an inner rod 73 and a third spring 72. Among them, the sleeve 71 is fixedly installed on the mounting ring 31. The inner rod 73 is slidably installed on the inner wall of the end of the sleeve 71 away from the mounting ring 31. The third spring 72 is fixedly installed between the inner rod 73 and the sleeve 71.

[0052] It can be understood that the automatic reset of the inner rod 73 and the sleeve 71 is realized through the third spring 72 to achieve the telescopic effect.

[0053] Please continue to refer to Figure 2 and Figure 9 In the exemplary embodiment, the closing assembly can include hinges 8, baffles 81, push rods 82 and fourth springs 83. Among them, two hinges 8 are provided, symmetrically and fixedly installed at one end of the fixed cylinder 2 away from the mounting post 3. Two baffles 81 are provided, hinged on the hinges 8. The push rods 82 are slidably installed in the positioning holes 22 and penetrate through the fixed cylinder 2. The fourth springs 83 are fixedly installed between the push rods 82 and the positioning holes 22.

[0054] Specifically, during installation, when the telescopic rod 7 extends into the positioning hole 22, it will press the push rod 82. The push rod 82 slides along the positioning hole 22 into the pipeline to lift the baffle 81, opening the baffle 81 before the sensor 4 reaches the inner wall of the pipeline, avoiding direct contact between the sensor 4 and the baffle 81, thus protecting the sensor 4. During disassembly, the same reverse process enables the sensor 4 to pass through the pipeline wall first, and then the telescopic rod 7 leaves the push rod 82. The push rod 82 resets under the action of the fourth spring 83. A torsion spring is provided in the hinge 8. After the push rod 82 leaves, the baffle 81 closes under the action of the torsion spring, achieving isolation of the flue gas.

[0055] Further, sealing plates 811 are fixedly installed at the ends of both baffles 81 away from the hinge 8. One sealing plate 811 is arranged on the top of the baffle 81 connected thereto, and the other sealing plate 811 is arranged on the bottom of the baffle 81 connected thereto. The push rod 82 corresponding to the baffle 81 with the sealing plate 811 at the bottom is shorter than the other push rod 82.

[0056] Specifically, corresponding sealing plates 811 are arranged opposite to the two baffles 81. After the two sealing plates 811 are staggered, a better closing effect can be achieved. And the push rod 82 corresponding to the baffle 81 with the sealing plate 811 at the bottom is shorter than the other push rod 82, which can ensure that this baffle 81 closes first, so that the other sealing plate 811 can overlap with it to achieve the closing function.

[0057] Please refer to Figure 9 , in an exemplary embodiment, the cleaning assembly may include a liquid storage tank 9, a siphon tube 91, and a cleaning cotton 92. Among them, the liquid storage tank 9 is fixedly installed on the inner side wall of one end of the fixed cylinder 2 away from the mounting post 3. The siphon tube 91 is fixedly installed in the liquid storage tank 9, and the siphon tube 91 penetrates through the liquid storage tank 9. The cleaning cotton 92 is fixedly installed in the fixed cylinder 2 and is connected to the siphon tube 91.

[0058] Specifically, the liquid storage tank 9 is filled with a cleaning liquid. The cleaning liquid is sucked out through the siphon tube 91 to the cleaning cotton 92 connected thereto, so that the cleaning cotton 92 can always maintain the cleaning liquid. During the process of loading and unloading the sensor 4, the sensor 4 can be cleaned by the cleaning cotton 92 to remove dust, ensuring the normal operation of the sensor 4.

[0059] Further, the liquid storage tank 9 is arranged in a ring shape, and the cleaning cotton 92 is arranged inside the liquid storage tank 9. An opening is provided in the center of the cleaning cotton 92, and the opening is slightly smaller than the outer diameter of the sensor 4.

[0060] It can be understood that the opening provided on the cleaning cotton 92 is smaller than the outer diameter of the sensor 4, which can fully wipe and clean the sensor 4.

[0061] The gas boiler flue gas emission monitoring device proposed in the embodiment of the present application can achieve the rapid installation and disassembly of the sensor 4 and the fixed cylinder 2 through the cooperation of the operation component and the locking component. Then, through the positioning component, it can ensure that the positioning component is connected prior to the fixed cylinder 2 during installation to protect the sensor 4. Secondly, through the sealing component, it can seal the opening of the fixed cylinder 2 in the chimney when the sensor 4 is removed to prevent the flue gas from discharging from the fixed cylinder 2 and scalding the staff. Finally, through the cleaning component, the soot on the surface of the sensor 4 can be automatically removed when the sensor 4 is taken out to ensure the cleanliness of the sensor 4. Through the cooperation of the above structures, the components such as the sensor 4 can be installed and disassembled quickly and conveniently, which can not only reduce the work difficulty during maintenance, but also better protect the sensor 4 during disassembly and assembly to avoid damage to the sensor 4.

[0062] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present application by the same token.
