Abstract
Description
[Technical field]
[0001] The present invention relates to the technical field of smoke monitoring, and in particular to a mounting structure and a smoke monitoring device. [Background technology]
[0002] A thermal power plant is a device that generates electricity by burning fossil fuels (such as coal, oil, natural gas, etc.) to produce steam to drive a turbine generator. The fuel combustion process produces large amounts of exhaust gas and smoke, both of which have adverse effects on the environment and human health. Therefore, in order to protect the environment and human health, it is necessary to install smoke monitoring devices in thermal power plants to monitor the exhaust gas emissions.
[0003] Smoke monitoring devices in thermal power plants are usually installed in the chimney or exhaust pipe of exhaust gas. In order to ensure the accuracy of monitoring, the monitoring points should be reasonably selected based on the location and number of the exhaust outlets, thereby ensuring the area covered and representativeness of the monitoring. During long-term operation, dust, particulate matter, chemicals, etc. in the smoke may block or contaminate important components such as the sensor and filter of the monitoring device, resulting in a decrease in the accuracy of the monitoring device or the occurrence of failure, which will affect the accuracy of the monitoring results. Therefore, the smoke monitoring device should be periodically removed for cleaning and maintenance.
[0004] Conventional smoke monitoring devices are usually fixedly installed on the chimney of a power plant by flanges and bolts. When the smoke monitoring devices are removed for maintenance, they need to be removed one by one with specific tools, which makes the operation process complicated and time-consuming. Therefore, the present invention proposes an installation structure, which can realize quick installation and removal of the smoke monitoring device, making it easier for workers to operate and improving work efficiency. In addition, in view of the fact that dust, particulate matter, chemicals, etc. in the smoke may block or contaminate the smoke extraction duct of the monitoring device, the conventional cleaning method involves removing the smoke extraction duct, cleaning it thoroughly, and then reinstalling it, which is a complicated and time-consuming process. Therefore, the present invention installs a corresponding cleaning tool in the smoke extraction duct, which makes it easier to clean the duct, prevents it from being blocked, and improves the work efficiency of workers.

[0024] In the following description, numerous specific details are set forth to facilitate a thorough understanding of the present invention; however, the present invention may be embodied in other ways different from those described herein, and those skilled in the art may make similar generalizations without departing from the scope of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.
[0025] In the following, references to "one embodiment" or "an embodiment" refer to a particular feature, structure, or characteristic that may be included in at least one implementation of the present invention. References to "in one embodiment" in various places in the specification do not necessarily all refer to the same embodiment, nor are they separate or alternative embodiments that are mutually exclusive of other embodiments.
[0026] Example 1 1 to 5, which is a first embodiment of the present invention, which provides a mounting structure for quickly mounting and fixing a smoke detection device, includes a mounting base 100, a mounting block 200 matingly mounted on the mounting base 100, a pivot assembly 300 mounted in the mounting base 100, and a fixed assembly 400 mounted on the pivot assembly 300. A cavity 101 is provided in the mounting base 100. The pivot assembly 300 includes a pivot member 301 rotatably mounted in the cavity 101, a driving member 302 mounted in the mounting base 100, and a connecting member 303 mounted in the mounting base 100 and mating with the pivot member 301, and the fixing assembly 400 includes a lever member 401 rotatably connected to the connecting member 303, a clamp member 402 fixedly mounted on one end of the lever member 401, and a reset member 403 mounted in the mounting base 100 and fixedly connected to the lever member 401.
[0027] In this embodiment, the mounting base 100 is fixedly mounted on the chimney of the power plant and used to mount the entire device. The mounting block 200 is fixedly connected to the monitoring device, and the monitoring device is quickly mounted on the mounting base 100 through the mounting block 200. A cavity 101 is opened in the mounting base 100 and used to receive and mount the rotating member 301. A driving member 302 is provided in the mounting base 100 and matches with the rotating member 301, and used to drive the rotating member 301 to rotate. There are a total of four sets of connecting members 303, which are distributed in a rectangle surrounding the rotating member 301; there are a total of four sets of lever members 401, which are respectively provided to match the connecting members 303; there are a total of four sets of clamping members 402, which are provided to match the lever members 401; and there are a total of four sets of resetting members 403, which are provided to match the lever members 401, and are used to support the lever members 401 against their initial position and to reset them after rotation has occurred.
[0028] Specifically, the rotating member 301 includes a cam 301a rotatably attached within the cavity 101, a bump 301b provided on the cam 301a, and an arc-shaped abutment surface 301c provided on one end of the bump 301b. The driving member 302 includes an L-shaped movable groove 302a opened within the mounting base 100, an L-shaped driving rod 302b movably attached within the L-shaped movable groove 302a, a stopper ring groove 302c opened within the mounting base 100 and communicating with the L-shaped movable groove 302a, and a stopper ring 302d located within the stopper ring groove 302c and fixedly welded to one end of the L-shaped driving rod 302b.
[0029] In this embodiment, the cam 301a is rotatably mounted in the cavity 101, and four bumps 301b are provided in an annular shape, and the arc-shaped abutment surface 301c of the bumps 301b contacts the edge of the cavity 101, so that the cam 301a can rotate without being displaced in the cavity 101. The L-shaped movable groove 302a is opened in the mounting base 100 and communicates with the cavity 101 at one side, so that the L-shaped driving rod 302b therein abuts against the arc-shaped abutment surface 301c when moving, and the cam 301a rotates accordingly. The stopper ring groove 302c is provided on the inner wall of one end of the L-shaped movable groove 302a, in which a stopper ring 302d is movably mounted, and the stopper ring 302d is fixedly fitted to the L-shaped driving rod 302b, thereby realizing a position limit for the L-shaped driving rod 302b. When the L-shaped driving rod 302b moves, it drives the stopper ring 302d to move in the stopper ring groove 302c, and prevents the L-shaped driving rod 302b from tilting in the L-shaped movable groove 302a when it moves.
[0030] Furthermore, the connecting member 303 includes a connecting rod groove 303a opened in the mounting base 100 and communicating with the cavity 101, a connecting rod 303b movably inserted in the connecting rod groove 303a and extending into the cavity 101, and a spherical abutment surface 303c provided on one end of the connecting rod 303b. The lever member 401 includes a lever pivot groove 401a opened in the mounting base 100 and communicating with the connecting rod groove 303a, a lever 401b located in the lever pivot groove 401a and rotatably connected to one end of the connecting rod 303b, and a lever pivot shaft 401c provided in the mounting base 100 and rotatably attached to the lever 401b.
[0031] In this embodiment, the connecting rod 303b has one end located in the connecting rod groove 303a and pivotally connected to the lever 401b, and the other end extending into the cavity 101, in which the spherical abutment surface 303c is used to contact the lowest point of the bump 301b and drive the connecting rod 303b to slide thereon when the bump 301b pivots, pressing the connecting rod 303b into the connecting rod groove 303a, thereby pressing the lever 401b to rotate around the lever pivot axis 401c. The lever 401b is divided into two ends by the lever pivot shaft 401c, one end connected to the connecting rod 303b is a short arm end, and the other end connected to the arc-shaped clip 402b is a long arm end, the length of the short arm end being shorter than the length of the long arm end, so that by pivoting the short arm end a small distance, the end point of the long arm end can be moved a large distance, and the arc-shaped clip 402b is further driven to engage with the clip groove 402a.
[0032] Here, the clamping member 402 includes a clip groove 402a opened in the mounting block 200, an arc-shaped clip 402b fixedly connected to one end of the lever 401b and matching the clip groove 402a, and an engaging arc surface 402c provided on the arc-shaped clip 402b.
[0033] In this embodiment, the clip groove 402a is opened in the mounting block 200 and cooperates with the arc-shaped clip 402b to quickly fix the mounting block 200 to the mounting base 100. The arc-shaped clip 402b is provided with an engaging arc surface 402c in the direction toward the clip groove 402a. The arc-shaped design of the engaging arc surface 402c makes it easier for the arc-shaped clip 402b to engage with the clip groove 402a and serves as a guide.
[0034] In use, the mounting block 200 is placed in the center of the circular arc clip 402b, and the L-shaped driving rod 302b is pushed to move in the L-shaped movable groove 302a. When the L-shaped driving rod 302b abuts against the circular arc abutment surface 301c, the L-shaped driving rod 302b continues to move and drives the bump 301b to move, and the movement of the bump 301b drives the cam 301a to rotate, thereby driving the spherical abutment surface 303c on the connecting rod 303b to slide along the edge of the movement of the bump 301b to the highest point of the bump 301b; As a result, the connecting rod 303b is pushed into the connecting rod groove 303a, and the connecting rod 303b presses the short arm end of the lever 401b to rotate the lever 401b around the lever rotation axis 401c, and further, the long arm end of the lever 401b drives the arc-shaped clip 402b thereon to engage with the clip groove 402a in the mounting block 200, thereby realizing rapid mounting and fixing of the mounting block 200, and finally realizing rapid mounting and fixing of the smoke detection device fixed and welded to the mounting block 200 at the monitoring position.

[0036] In this embodiment, the reset groove 403a communicates with the lever pivot groove 401a and the connecting rod groove 303a, and the reset spring 403b is located in the reset groove 403a, with one end fixedly connected to the inner wall of the reset groove 403a and the other end fixedly connected to the short arm end of the lever 401b, which is used to support the lever 401b in the initial state. When the short arm end of the lever 401b rotates to press the reset spring 403b, the tension of the reset groove 403a pushes the short arm end of the lever 401b to return to its initial position, thereby resetting the state of the lever 401b, which drives the arc-shaped clip 402b to leave the clip groove 402a and return to its initial position, thereby realizing the unlocking after the mounting block 200 is fixed, and finally realizing the quick removal of the smoke detector.
[0037] Specifically, a sleeve 102 is further provided on the mounting base 100, a first through hole 103 is further opened in the mounting base 100, a second through hole 301a-1 is opened in the cam 301a, and a welding through hole 201 is opened in the mounting block 200.

[0039] The other structures are the same as those in the first embodiment.
[0040] In use, the L-shaped driving rod 302b is pulled back, and the L-shaped driving rod 302b slides on the arc-shaped abutment surface 301c when moving back, thereby driving the bump 301b to slide back, and the bump 301b rotates to drive the cam 301a to rotate, so that the spherical abutment surface 303c on the connecting rod 303b slides along the edge of the bump 301b's movement to the lowest point of the bump 301b, and the connecting rod 303b returns to its initial state, and this At this time, the short arm end of the lever 401b is not pressed by the connecting rod 303b, and the relaxation force of the reset spring 403b pushes and moves the short arm end of the lever 401b back to its initial state, thereby driving and moving the arc-shaped clip 402b at the long arm end of the lever 401b, causing it to disengage from the clip groove 402a and return to its initial position, that is, realizing the unlocking after the mounting block 200 is fixed, and finally realizing the quick removal of the smoke detection device.
