Description

Technical Field

[0001] This utility model relates to the field of measuring cylinder unblocking technology, specifically a simple unblocking measuring cylinder device for power plants. Background Technology

[0002] In power plant operation, measuring cylinders (such as wind pressure measuring cylinders, guided wave radar measuring cylinders, etc.) are key equipment used to monitor parameters such as furnace negative pressure, flue gas pressure, and material level. Their accuracy directly affects process control and equipment safety.

[0003] Power plants contain a large amount of dust in their flue gas during operation, which tends to accumulate on the inner wall of the measuring cylinder after long-term operation. Existing technologies usually require disassembling the measuring cylinder or cutting the welded pipes before unblocking them. Then, the inner wall of the measuring cylinder is flushed under high pressure or a long rod is inserted into the blockage to clear it. The operation is not only cumbersome, but also requires repeated installation and disassembly of the measuring cylinder, which reduces production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a simple unblocking measuring cylinder device for power plants, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a simple unblocking measuring cylinder device for power plants, comprising a measuring cylinder body and a disassembly cover. One end of the outer surface of the measuring cylinder body has an external thread, and one side of the measuring cylinder body has an opening. The inner wall of the disassembly cover has an internal thread, and one side of the outer surface of the disassembly cover has a stabilizing groove. A rotating disk is rotatably mounted on one side of the outer wall of the disassembly cover. A protruding plate is fixedly connected to one side of the rotating disk, and a locking block is slidably mounted on the other side of the rotating disk. A spring is fixedly mounted inside the rotating disk, and a transmission rod is fixedly connected to the other side of the rotating disk. A mounting base is fixedly mounted at the inner end of the rotating disk. The mounting base extends into the interior of the measuring cylinder body. Guide blocks are fixedly mounted at both the front and rear ends of the mounting base. A cavity is formed inside the mounting base. A first scraper and a second scraper are rotatably mounted at the upper and lower ends of the mounting base, respectively. A first connecting rod is fixedly mounted inside the first scraper, and a second connecting rod is fixedly mounted inside the second scraper.

[0006] Preferably, the inner wall of the disassembly cover is threadedly connected to the outer surface of the measuring cylinder body, and a sealing gasket is provided on the side of the measuring cylinder body.

[0007] Preferably, one end of the spring is fixedly connected to the side of the locking block, and one end of the locking block abuts against the inside of the stabilizing groove.

[0008] Preferably, the transmission rod rotatably passes through the mounting base and one end extends into the cavity.

[0009] Preferably, the first scraper and the second scraper have the same structure but opposite directions, a limiting rod is fixedly connected to the surface of the first connecting rod, a limiting groove is formed inside the guide block, and the limiting rod is rotatably installed inside the limiting groove.

[0010] Preferably, one end of the surface of both the first connecting rod and the second connecting rod is rotatably mounted inside the cavity. The surface of the first connecting rod is fixedly mounted with a first gear and a worm gear, respectively, and one end of the surface of the second connecting rod is fixedly mounted with a second gear. The top of the second gear meshes with the bottom of the first gear.

[0011] Preferably, a worm is fixedly connected to one side of the transmission rod, and the top of the worm meshes with the bottom of the worm wheel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by additionally opening an opening on one side of the measuring cylinder body, it is convenient to clean the inside of the measuring cylinder body later without disassembling or cutting the measuring cylinder body. The opening is covered by the installed disassembly cover, thereby ensuring the normal use of the measuring cylinder body. The disassembly cover can be rotated to remove it from one end of the measuring cylinder body, thus facilitating the cleaning and discharge of debris inside the measuring cylinder body later.

[0014] 2. In this utility model, the first scraper and the second scraper are installed inside the measuring cylinder. Through the cooperation between the transmission rod, worm, worm wheel, first gear and second gear, the first scraper and the second scraper can be rotated to adjust their angle. The first scraper and the second scraper rotate vertically and fit against the inner wall of the measuring cylinder body. This allows the first scraper and the second scraper to scrape off and push out the debris inside the measuring cylinder body when the cover is pulled outward, thereby reducing the difficulty of unclogging and cleaning the measuring cylinder body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] like Figures 1-6As shown, this utility model provides a technical solution: a simple unblocking measuring cylinder device for power plants, including a measuring cylinder body 1 and a disassembly cover 2. One end of the outer surface of the measuring cylinder body 1 has an external thread 101, and one side of the measuring cylinder body 1 has an opening 102. The inner wall of the disassembly cover 2 has an internal thread 201, and one side of the outer surface of the disassembly cover 2 has a stabilizing groove 202. A rotating disk 3 is rotatably mounted on one side of the outer wall of the disassembly cover 2. A protruding plate 31 is fixedly connected to one side of the rotating disk 3, and a locking block 32 is slidably mounted on the other side of the rotating disk 3. A spring 33 is fixedly installed inside the rotating disk 3. A transmission rod 34 is fixedly connected to the other side of the rotating disk 3. A mounting base 4 is fixedly installed at the inner end of the rotating disk 3. The mounting base 4 extends into the interior of the measuring cylinder body 1. Guide blocks 41 are fixedly installed at both the front and rear ends of the mounting base 4. A cavity 401 is opened inside the mounting base 4. A first scraper 5 and a second scraper 6 are rotatably installed at the upper and lower ends of the mounting base 4, respectively. A first connecting rod 51 is fixedly installed inside the first scraper 5. A second connecting rod 61 is fixedly installed inside the second scraper 6. The inner wall of the disassembly cover 2 is threadedly connected to the outer surface of the measuring cylinder body 1. A sealing gasket 11 is provided on the side of the measuring cylinder body 1.

[0025] In this embodiment, the disassembly cover 2 is threadedly connected to the measuring cylinder body 1, allowing the disassembly cover 2 to be easily installed and removed by rotating it after being aligned with the measuring cylinder body 1. The opening 102 on the side of the measuring cylinder body 1 facilitates the later cleaning and unclogging of the interior of the measuring cylinder body 1. The disassembly cover 2 covers the opening 102, thereby ensuring the normal use of the measuring cylinder body 1. The sealing gasket 11 is located at the connection position between the disassembly cover 2 and the measuring cylinder body 1, which can ensure the sealing when the opening 102 is closed and prevent the leakage of measurement flue gas.

[0026] Example 2

[0027] like Figures 1-6 As shown, one end of the spring 33 is fixedly connected to the side of the locking block 32, and one end of the locking block 32 abuts against the inside of the stabilizing groove 202. The transmission rod 34 rotates through the mounting base 4 and one end extends into the cavity 401. The first scraper 5 and the second scraper 6 have the same structure but opposite directions. The surface of the first connecting rod 51 is fixedly connected to the limiting rod 52. The guide block 41 has a limiting groove 411 inside, and the limiting rod 52 is rotatably installed inside the limiting groove 411. One end of the surface of the first connecting rod 51 and the second connecting rod 61 is rotatably installed inside the cavity 401. The surface of the first connecting rod 51 is fixedly mounted with the first gear 53 and the worm gear 54, respectively. One end of the surface of the second connecting rod 61 is fixedly mounted with the second gear 62. The top of the second gear 62 meshes with the bottom of the first gear 53. One side of the transmission rod 34 is fixedly connected to the worm 35, and the top of the worm 35 meshes with the bottom of the worm gear 54.

[0028] In this embodiment, the worm gear 35 meshes with the worm wheel 54, the first gear 53, and the second gear 62, so that when the rotating disk 3 drives the transmission rod 34, the first connecting rod 51 and the second connecting rod 61 rotate, which can adjust the angle of the first scraper 5 and the second scraper 6. The installed protruding plate 31 facilitates the torsion of the rotating disk 3, while the locking block 32 is pushed by the spring 33, causing one end to abut against the inside of the stabilizing groove 202. The locking block 32 can slide under pressure, allowing the rotating disk 3 to rotate, thereby increasing the rotational resistance of the rotating disk 3 and improving the rotational efficiency of the rotating disk 3. Stability is ensured to prevent external influences from causing the rotating disk 3 to shake and affecting the installation of the first scraper 5 and the second scraper 6. The limiting rod 52 is installed inside the limiting groove 411 to ensure that the position of the first connecting rod 51 is fixed. Similarly, the second connecting rod 61 is fixed to prevent the first connecting rod 51 and the second connecting rod 61 from moving and affecting the meshing stability of the first gear 53 and the second gear 62. At the same time, the limiting groove 411 can limit the rotation angle of the first scraper 5 and the second scraper 6 to avoid the first scraper 5 and the second scraper 6 from rotating too much and failing to meet the inner wall, thus affecting the dredging and cleaning effect.

[0029] Working principle: By rotating the disassembly cover 2 to one end of the opening 102 of the measuring cylinder body 1, the sealing gasket 11 ensures the sealing of the opening 102. The mounting base 4 extends into the measuring cylinder body 1, and the first scraper 5 and the second scraper 6 are kept horizontal to prevent the first scraper 5 and the second scraper 6 from affecting the flow of flue gas and causing the measuring cylinder body 1 to malfunction. When the inside of the measuring cylinder body 1 is blocked and needs to be cleared, the protruding plate 31 on the surface of the rotating disk 3 is rotated first, which drives the transmission rod 34 and the worm gear 35 to rotate. The worm gear 35 meshes with the worm wheel 54, driving the first connecting rod 51 to rotate. Gear 53 meshes with the second gear 62, causing the second connecting rod 61 to rotate together. The limiting groove 411 limits the angle of the limiting rod 52, causing the first scraper 5 and the second scraper 6 to rotate into a vertical state. At this time, the first scraper 5 and the second scraper 6 together press against the inner wall of the measuring cylinder body 1. Then, the disassembly cover 2 is rotated and removed from one end of the measuring cylinder body 1. The disassembly cover 2 is pulled outward to pull the first scraper 5 and the second scraper 6 outward. The first scraper 5 and the second scraper 6 clear the debris that is stuck on the inner wall of the measuring cylinder body 1 and push it into the opening 102 for discharge, thereby facilitating and quickly clearing the blocked measuring cylinder body 1.
