Description

Technical Field

[0001] The utility model relates to the technical field of monitoring equipment, in particular to an environmental protection flue gas monitoring device for power plants. Background Art

[0002] Environmental protection flue gas monitoring can monitor and analyze the exhaust gas emissions of thermal power plants in real time, detect abnormal conditions in a timely manner and take corresponding measures to reduce exhaust gas emissions. Therefore, it is very important for thermal power plants to carry out environmental protection flue gas monitoring. However, most existing environmental protection flue gas monitoring devices do not have protective structures. When the flue gas monitoring device is hit, it is easy to cause damage to the device. Moreover, due to long-term exposure to the exhaust port, the environmental protection flue gas monitoring device is easily corroded by impurities such as flue gas and dust, causing internal damage, thereby reducing the service life of the device.

[0003] After searching, it was found that the announcement number is CN220570764U, and the name is an environmental protection flue gas monitoring device for thermal power plants. The application proposed an existing patent with announcement number CN214248135U, which proposed an environmental protection flue gas monitoring device for thermal power plants. The environmental protection flue gas monitoring device for thermal power plants only protects the two sides of the flue gas monitoring device body through the protective mechanism, but cannot achieve the protection effect for other parts of the flue gas monitoring device. At the same time, the dust and other impurities generated by the thermal power plant can easily invade the interior of the flue gas monitoring device body, causing internal damage. The problem of the protective cover, base and The design of the fixing components protects the monitoring device body. On the one hand, it avoids the monitoring device body from being eroded by flue gas, and solves the problem that the existing environmentally friendly flue gas monitoring device is easily damaged by the erosion of flue gas, dust and other impurities due to long-term exposure to the exhaust port. On the other hand, it avoids the damage caused by collision to the monitoring device body. However, when using this application, it is necessary to first fix the monitoring device body and then install the protective cover. There are many operating procedures and the installation and disassembly are relatively troublesome. At the same time, the vertical limit of the monitoring device body is insufficient, and the installation stability is not high, and further improvements can be made.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0027] According to an embodiment of the present utility model, an environmental protection flue gas monitoring device for a power plant is provided.

[0028] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. Figure 1-4As shown, according to an embodiment of the present invention, an environmental flue gas monitoring device for a power plant includes a monitoring device body 1, a top tube 2 and a base 9. A monitoring portion 12 is installed at the detection end of the monitoring device body 1, which is a structure disclosed in the art and will not be described in detail here. An extrusion rod 5 is fixedly connected to the inner bottom surface of the base 9, and an extrusion block 6 is fixedly installed on the outer surface of the extrusion rod 5. The top tube 2 includes an extrusion section 3 and a connecting section 4, and the connecting section 4 is threadedly connected to the base 9. A bottom hole 11 is opened through the bottom surface of the base 9, and a rubber pad 10 is fixedly bonded to the inner bottom surface of the base 9. The thickness of the rubber pad 10 is not less than 3 mm. A top block 7 is fixedly installed on the inner top surface of the top tube 2. When the monitoring device body 1 is installed, the monitoring portion 12 of the monitoring device body 1 passes through the bottom hole 11. Subsequently, the staff can rotate the top tube 2 and the base 9 to connect the threads, and the connecting section 4 on the bottom surface of the top tube 2 is connected to the base 9. During the connection process, the inner wall of the extrusion section 3 pushes the extrusion block 6 to move inward synchronously, driving the extrusion rod 5 to deform and press against the monitoring device body 1, thereby fixing the monitoring device body 1 in the horizontal direction. At the same time, after the top tube 2 and the base 9 are fixed, the top block 7 presses against the monitoring device body 1 to fix the monitoring device body 1 in the vertical direction, thereby preventing the monitoring device body 1 from shaking and improving the stability of the installation. At the same time, the monitoring device body 1 can be fixed synchronously when the top tube 2 is installed, and the monitoring device body 1 can be released synchronously when the top tube 2 is removed, which reduces the operation process and is more convenient and simple to use.

[0029] In one embodiment, the extrusion section 3 is an inclined surface, and the slope of the extrusion section 3 is the same as the slope of the outer wall of the extrusion block 6. By utilizing the principle of inclined wedge, the extrusion block 6 is pushed horizontally inward when the top cylinder 2 is installed, driving the extrusion rod 5 to press against the monitoring device body 1.

[0030] In one embodiment, an external thread is provided on the outer surface of the bottom of the connecting section 4, and an internal thread is provided on the inner wall of the base 9, and the internal thread and the external thread are threadably matched, which is a common connection structure.

[0031] In one embodiment, the extrusion rod 5 adopts a flexible structure, and a plurality of extrusion rods 5 are distributed at equal angles, and the extrusion rods 5 are distributed at equal angles along the central axis of the base 9 .

[0032] In one embodiment, a lifting ring 8 is fixedly installed on the top surface of the top tube 2 for easy hanging, and a rubber pad 10 is laid on the inner bottom surface of the base 9. When the top tube 2 is installed, the top block 7 squeezes the monitoring device body 1, and the bottom surface of the monitoring device body 1 squeezes the rubber pad 10, causing the rubber pad 10 to deform. The rubber pad 10 is tightly sealed against the bottom surface of the monitoring device body 1, thereby preventing impurities from entering and improving the sealing performance. At the same time, the lifting ring 8 located on the top surface of the top tube 2 facilitates the hanging and installation of the device, thereby improving the convenience of use.

[0033] In one embodiment, the bottom hole 11 is opened corresponding to the monitoring portion 12 , and the diameter of the bottom hole 11 is larger than the outer diameter of the monitoring portion 12 , so as to facilitate passage of the monitoring portion 12 .

[0034] Working principle:

[0035] When installing the monitoring device body 1, the monitoring part 12 of the monitoring device body 1 passes through the bottom hole 11. Then, the staff can rotate the top tube 2 and the base 9 to connect the threads. The connecting section 4 on the bottom of the top tube 2 is connected to the base 9. During the connection process, the inner wall of the extrusion section 3 pushes the extrusion block 6 to move inward synchronously, driving the extrusion rod 5 to deform and press against the monitoring device body 1, thereby fixing the monitoring device body 1 in the horizontal direction. At the same time, after the top tube 2 and the base 9 are fixed, the top block 7 presses against the monitoring device body 1 to fix the monitoring device body 1 in the vertical direction, thereby preventing the monitoring device body 1 from shaking and improving the stability of the installation. Qualitative, at the same time, when installing the top tube 2, the monitoring device body 1 can be fixed simultaneously, and when removing the top tube 2, the monitoring device body 1 can be released simultaneously, which reduces the operation process and is more convenient and simple to use. At the same time, the rubber pad 10 is laid on the bottom surface of the base 9. When installing the top tube 2, the top block 7 squeezes the monitoring device body 1, and the bottom surface of the monitoring device body 1 squeezes the rubber pad 10, causing the rubber pad 10 to deform. The rubber pad 10 is tightly sealed against the bottom surface of the monitoring device body 1, which avoids the entry of impurities and improves the sealing performance. At the same time, the lifting ring 8 located on the top surface of the top tube 2 facilitates the hanging installation of the device and improves the convenience of use.
