Description

Technical Field

[0001] The invention relates to the technical field of air locks, and in particular to an operating state monitoring device for an air lock of a power plant. Background Art

[0002] The air lock is one of the important components of the pulverizing system of coal-fired units in power companies. Its purpose is to prevent air crossflow when coal powder or ash particles enter another pressure range from a certain pressure range, and to maintain the smooth flow of powder particles. The diameter of the air lock is equal to the diameter of the pipeline. The working principle of the air lock is the lever action. There is a flap or cone cap inside the pipeline, which is connected to the outside through a lever. The external lever is equipped with a counterweight. The powder particles inside the pipeline cause the lever to move by their own weight, and the position of the counterweight can adjust the amount of powder particles passing through the pipeline.

[0003] In a normally operating powder making system, the air lock works normally. If there is a blockage in the pipeline and no powder particles flow, the air lock will not work. This is an abnormality in the powder making system and needs to be promptly contacted for maintenance. Especially when the air lock of the fine powder separator stops working, it may be due to blockage in the upper pipeline or deviation of the air lock pin or the weight hammer. At this time, the powder is abnormal. When the situation worsens, it will further lead to a series of serious consequences such as powder discharge machine carrying powder, powder making system explosion, personal injury, equipment damage, etc. At present, the operation of most air locks in power plants is only checked regularly on site by patrol inspections. Once there is a major operation or abnormal handling, the patrol inspection cannot detect the abnormality of the air lock in time.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0037] Example 1

[0038] Reference Figure 1 to Figure 4 , which is the first embodiment of the present invention, provides a power plant air lock operation status monitoring device, including, an air lock body 100, on which a transmission shaft 101 is installed, and the interior of the transmission shaft 101 is connected to an internal lever; a rotating component 300, which includes a movable rod 1 302, an auxiliary part 301 arranged on the movable rod 1 302, a movable rod 2 303 arranged on the auxiliary part 301, and a conductive sheet 1 304 arranged on the auxiliary part 301; a movable component 200, which includes a movable part 203, a mounting frame 201 arranged on the movable part 203, a triggering part 202 arranged on the mounting frame 201, and a conductive sheet 2 204 arranged on the triggering part 202.

[0039] Among them, the movable rod 1 302 is arranged on the transmission shaft 101 through the installation component 400, and the transmission shaft 101 can drive the movable rod 1 302. The auxiliary part 301 and the movable rod 2 303 form a whole that swings in the opposite direction synchronously with the internal lever. The counterweight block 305 in the prior art is installed and set on the end of the movable rod 2 303 away from the air lock body 100. The movable part 203 is movably set on the movable rod 1 302, the auxiliary part 301 and the movable rod 2 303. The auxiliary part 301 can clamp the trigger part 202 that moves toward the direction of the air lock body 100, so that the conductive sheet 1 304 and the conductive sheet 2 204 are accurately in contact. When the trigger part 202 returns, the conductive sheet 1 304 and the conductive sheet 2 204 are avoided from contacting, so that a signal can only be sent once in one lever movement cycle.

[0040] Furthermore, the conductive sheet 1 304 and the conductive sheet 2 204 are connected to the positive and negative electrodes of the power supply through wires, and a signal generator is connected in series to the circuit formed by the conductive sheet 1 304, the conductive sheet 2 204 and the power supply. The power supply and the signal generator are both existing technologies. In this embodiment, their volume and mass are small and they are fixedly installed on the movable part 203. When the conductive sheet 1 304 and the conductive sheet 2 204 are in contact, the circuit is closed and the signal generator sends a signal to the DCS system (distributed control system) of the power plant. When the two are not in contact, the DCS system of the power plant cannot receive the signal.

[0041] In summary, when the air lock body 100 is working, the internal lever of the air lock body 100 will swing up and down periodically, and the transmission shaft 101 will drive the rotating assembly 300 to swing up and down in the opposite direction synchronously. When the end of the movable rod 2 303 away from the transmission shaft 101 moves to the lowest point, the movable assembly 200 will also move to the end of the rotating assembly 300 away from the transmission shaft 101 due to its own gravity. When the rotating assembly 300 rotates upward as a whole, the end of the movable rod 2 303 away from the transmission shaft 101 gradually becomes higher than the other end. The movable component 200 as a whole will move toward the side of the transmission shaft 101 due to its own gravity, and move from the movable rod 2 303 to the movable rod 1 302 through the auxiliary part 301. When the trigger part 202 moves, it can be temporarily stuck by the auxiliary part 301, and the conductive sheet 2 204 can abut against the conductive sheet 1 304, ensuring that the signal circuit can be stably connected and the signal can be accurately sent out. A signal is sent out once in each lever movement cycle. When the DCS system does not receive a signal for more than 15 seconds, an alarm is issued, which can play a role in real-time monitoring.

[0042] Example 2

[0043] Reference Figure 2 to Figure 4 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a limiting groove 201a is provided in the mounting frame 201; the triggering part 202 includes a block 202a slidably disposed in the limiting groove 201a, a connecting rod 202b fixedly disposed at the end of the block 202a away from the movable member 203, and a spring 202c fixedly connected to the end of the block 202a away from the movable frame, the spring 202c being disposed on the periphery of the connecting rod 202b, and the other end of the spring 202c being fixedly connected to the movable frame. On the innermost wall of the limiting groove 201a, one end of the connecting rod 202b away from the movable part 203 can be exposed outside the mounting frame 201, the block 202a and the connecting rod 202b can both conduct electricity, the spring 1 202c is a non-conductive plastic spring, and the wire of the circuit is connected to the exposed end of the connecting rod 202b. In addition, the movable rod 1 302 and the movable rod 2 303 are both provided with channels for the block 202a to move, which will not affect the movement of the trigger part 202 on the movable rod 1 302 and the movable rod 2 303.

[0044] The mounting frame 201 is movably arranged on the movable rod 1 302, the auxiliary part 301 and the movable rod 2 303. One end of the clamping block 202a penetrates into the inner side of the movable part 203. The movable part 203 is provided with a hole for the movable part 203 to move. The clamping block 202a includes a protruding section 202a-2 and an inclined section 202a-1 adjacent to the protruding section 202a-2. When the movable part 203 is located on the movable rod 2 303, the inclined section 202a-1 faces the auxiliary part 301, and the conductive sheet 1 304 is fixedly arranged on the protruding section 202a-2.

[0045] Both the movable rod 1 302 and the movable rod 2 303 are provided with sliding grooves 205, and the two sliding grooves 205 are located in a straight line. A limiting rod 206 is fixedly arranged on the inner side of the movable part 203, and the limiting rod 206 is slidably arranged in the sliding groove 205. The limiting rod 206 is connected to at least one sliding groove 205, and the limiting rod 206 will not leave the sliding groove 205. The setting of the sliding groove 205 and the limiting rod 206 can limit the movable part 203, prevent the movable part 203 from driving the mounting frame 201 and the trigger part 202 to rotate, and enhance the stability of the trigger part 202.

[0046] The auxiliary part 301 includes a fixed column 301a fixedly arranged between the movable rod 1 302 and the movable rod 2 303, an abutment block 301b fixedly arranged on the fixed column 301a close to the side of the movable rod 2 303, a mounting block 301c fixedly arranged on the fixed column 301a, a matching block 301d movably arranged on the fixed column 301a, a spring 2 301e arranged between the matching block 301d and the movable rod 1 302, a conductive sheet 2 204 is arranged on the mounting block 301c, and the side of the mounting block 301c is in contact with the abutment block 301b. It should be noted that the central axes of the movable rod 1 302, the fixed column 301a and the movable rod 2 303 are in a straight line.

[0047] A protective groove 301f is provided on one side of the matching block 301d facing the fixed block, and the mounting block 301c and the conductive sheet 1 304 can enter the protective groove 301f. The matching block 301d can move to the outside of the conductive sheet 1 304 and cover the conductive sheet 1 304. The spring 2 301e can prevent the matching block 301d from covering the mounting block 301c and the conductive sheet 1 304 when it is not affected by the blocking block 202a of the trigger part 202.

[0048] The mating block 301d is in the shape of a truncated cone, and the outer surface of the abutment block 301b is inclined. The structural line of the inclined outer surface of the abutment block 301b in this embodiment is in the shape of an arc. The maximum diameter of the outer surface of the mating block 301d is equal to the maximum diameter of the outer surface of the abutment block 301b, and the maximum diameter surface of the abutment block 301b and the maximum diameter surface of the mating block 301d are close to each other.

[0049] In summary, refer to Figure 4 In the process of the movable member 203 moving from the movable rod 2 303 to the movable rod 1 302, the block 202a first abuts against the inclined surface of the abutment block 301b, and the block 202a can pass through the abutment block 301b through the cooperation of the inclined section 202a-1 of the block 202a and the inclined surface of the abutment block 301b, and then the spring 1 202c makes the block 202a rebound, so that the conductive sheet 2 204 located on the protruding section 202a-2 abuts against the conductive sheet 2 204 located on the mounting block 301c, and the circuit is connected, and the block 202a continues to move in the direction of the movable rod 1 302, and the radius of the inclined section 202a-1 of the block 202a and the matching block 301d is the maximum. 1 , and the block 202a contacts the edge line of the movable rod 302. If the block 202a continues to move in the direction of the movable rod 302, it will be squeezed by the matching block 301d, which will have a certain blocking effect on the block 202a, thereby prolonging the contact time between the conductive sheet 204 and the conductive sheet 1 304. The block 202a continues to move in the direction of the movable rod 302 and moves in the direction of the spring 1 202c to squeeze the spring 1 202c. When the block 202a moves to the position of the matching block 301d, the spring 1 202c will gradually rebound and return to its original state due to the truncated cone surface of the matching block 301d. Moreover, when the spring 1 202c is in its longest state, the end of the spring 1 202c will not contact the spring 2 301e.

[0050] In the process of the movable member 203 moving from the movable rod 1 302 to the movable rod 2 303, the protruding section 202a-2 of the block 202a first contacts the inclined surface of the matching block 301d, and the block 202a is squeezed to compress the spring 1 202c. At the same time, the spring 1 202c also makes the block 202a squeeze the matching block 301d, so that the matching block 301d pulls the spring 2 301e, driving the matching block 301d to move leftward so that the matching block 301d and the opposite surface of the abutment block 301b abut against each other, and the protective groove 301f covers the installation block 301c and Conductive sheet 1 304, until the protruding section 202a-2 of the block 202a moves to the side of the abutment block 301b, the matching block 301d is rebounded by the pulling force of the spring 2 301e, and the block 202a continues to move until the block 202a leaves the surface of the abutment block 301b and returns to its original state. During this process, the conductive sheet 204 set on the block 202a cannot contact the conductive sheet 1 304 set on the mounting block 301c. In this way, only one signal will be sent out in one movement cycle of the lever, so that the signal interval time is relatively stable, which is convenient for the staff to identify.

[0051] The remaining structures are the same as those of Example 1.

[0052] Example 3

[0053] Reference Figure 5-6, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the installation component 400 includes a docking portion 401 arranged on the movable rod 302, and a control portion 402 arranged on the docking portion 401.

[0054] Specifically, the docking portion 401 includes a mounting member 401a fixedly disposed at the end of the movable rod 302, a mounting member 401b fixedly disposed on the mounting member 401a, a transmission cover 401c fixedly disposed on the transmission shaft 101, a movable column 401d slidably disposed inside the mounting member 401b, a fixed shaft 401e fixedly disposed inside the mounting member 401b, a locking member 401f rotatably disposed on the fixed shaft 401e, and a mounting member 401c rotatably disposed on the transmission shaft 101. Part 401b is provided with a space for the locking member 401f to move; a slot 401c-1 is provided in the transmission cover 401c, and the locking member 401f can be inserted into the slot 401c-1. The locking member 401f, the fixed shaft 401e and the slot 401c-1 are arranged in two symmetrical groups. There are two protrusions at the opening of the transmission cover 401c, and the two slots 401c-1 are respectively located on the side of the two protrusions facing the inside of the transmission cover 401c.

[0055] A groove 401d-1 is provided in the movable column 401d, and a spring three 401g is fixedly provided on the innermost side of the movable column 401d close to the transmission shaft 101. The other end of the spring three 401g is fixedly connected to the mounting member two 401b. Most of the spring three 401g is arranged on the inner side of the movable column 401d to prevent the spring three 401g from excessive deformation. The movable column 401d can drive the locking member 401f to move through the groove 401d-1.

[0056] The locking member 401f includes an intermediate section 401f-2 rotatably connected to the fixed shaft 401e, a V-shaped section 401f-1 adjacent to the intermediate section 401f-2, and a transmission section 401f-3 adjacent to the intermediate section 401f-2; the V-shaped section 401f-1 can be stuck in the slot 401c-1, and the transmission section 401f-3 can abut against the inner wall of the groove 401d-1.

[0057] It should be noted that, when the rotating assembly 300 is not installed on the transmission shaft 101, the spring three 401g tightens the movable column 401d, and the groove 401d-1 is close to the inner wall of the mounting member 1 401a and abuts against the transmission section 401f-3 of the locking member 401f. The side surface of the locking member 401f close to the spring three 401g is lower on the left and higher on the right, and the left side is lower. When the rotating assembly 300 needs to be installed, the movable column 401d is controlled to move away from the spring three 401g. The inner wall of the groove 401d-1 near the spring three 401g side contacts the transmission section 401f-3, driving the transmission section 401f-3 to move around the fixed axis 401e in the direction away from the spring three 401g. The farthest ends of the two locking members 401f are close to each other, making it convenient for the staff to put the installation member 2 401b into the transmission cover 401c. When putting the installation member 2 401b into the transmission cover 401c, avoid the two protrusions. The side of the transmission shaft 101 near 1b contacts the innermost side of the transmission cover 401c. When the second mounting member 401b is rotated, the two locking members 401f are aligned with the two slots 401c-1. Then the movable column 401d is released, and the spring 3 401g rebounds. The movable column 401d drives the transmission section 401f-3 to rotate toward the direction close to the spring 3 401g through the inner wall of the groove 401d-1, so that the V-shaped section 401f-1 of the locking member 401f enters the slot 401c. -1, both sides of the V-shaped section 401f-1 can abut against the edge of the groove 401d-1 and then be released; the upper and lower sides of the V-shaped section 401f-1 of the locking member 401f are in contact with the upper and lower sides of the slot 401c-1, which can prevent the mounting member 401b and the transmission cover 401c from relative rotation, and the two sides of the V-shaped section 401f-1 respectively abut against the left and right edges of the groove 401d-1 to prevent the mounting member 401b from shifting left and right.

[0058] When the rotating assembly 300 needs to be removed, similarly to the above, the movable column 401d is controlled to move away from the spring three 401g, so that the locking member 401f can leave the slot 401c-1, and then the mounting member 2 401b can be taken out from the transmission cover 401c.

[0059] The control part 402 includes an inclined groove 402a opened in the movable column 401d, an inclined block 402b slidably set in the inclined groove 402a, a limit block 1 402c set at the wider end of the inclined block 402b, a limit block 2 402d set at the narrower end of the inclined block 402b, and a control block 402e set on the limit block 2 402d; the side of the inclined groove 402a close to the spring 3 401g is horizontally set, and the side away from the spring 3 401g is inclined. The left side of the inclined groove 402a is wider than the right side, and the same is true for the inclined block 402b. The limit blocks 1 402c, the limit blocks 2 402d and the control block 402e are all slidably connected to the inner wall of the mounting member 2 401b.

[0060] When the second mounting member 401b is installed in the transmission cover 401c, the control block 402e moves to the right, driving the inclined block 402b to move to the right synchronously, thereby driving the movable column 401d to move downward, stretching the spring three 401g and making the locking member 401f leave the slot 401c-1, so that the mounting assembly 400 can be taken out of the transmission cover 401c; release the control block 402e, the spring three 401g rebounds, driving the movable column 401d and the locking member 401f to return to their original state.

[0061] In summary, when the air lock fails and needs to be disassembled for maintenance or for convenience during equipment transportation, the movable component 200 and the rotating component 300 can be removed as a whole, and the installation component 400 can be used for quick disassembly and assembly. During installation, the control block 402e is pulled outward, and then the second installation component 401b is placed in the transmission cover 401c and the V-shaped section 401f-1 of the locking component 401f is aligned with the slot 401c-1, and then the control block 402e is released so that the installation component 400, the rotating component 300 and the movable component 200 can be stably installed on the transmission cover 401c as a whole; when the installation component 400 needs to be disassembled, the control block 402e is pulled outward to make the V-shaped section 401f-1 of the locking component 401f leave the slot 401c-1, and then the second installation component 401b is taken out, and then the control block 402e is released.

[0062] The remaining structure is the same as that of Example 2.
