Description

A steam turbine cylinder monitoring device Technical Field

[0001] This invention relates to the field of steam turbine cylinder technology, and in particular to a steam turbine cylinder monitoring device. Background Technology

[0002] The turbine cylinder is the outer shell of the turbine. During operation, in order to monitor the operating status of the cylinder in real time, temperature and pressure sensors are generally used for monitoring. When the cylinder leaks, the temperature will drop and the pressure will decrease, thus detecting whether the cylinder is functioning properly.

[0003] In use, existing temperature sensors are equipped with probes and instrument panels. When in use, the probe is inserted into the cylinder, and the instrument panel is on the outside of the cylinder. The instrument panel displays the information from the probe to reflect the situation inside the cylinder. However, during use, because high-temperature gas passes through the turbine and the temperature of the probe is lower than that of the steam, water droplets will condense on the side wall of the probe. This will affect the probe's temperature detection and thus affect the accuracy of temperature measurement.

[0004] Summary of the Invention

[0005] In view of the problem in the prior art that, due to the high temperature gas passing through the steam turbine and the probe temperature being lower than that of the steam, water droplets will condense on the side wall of the probe, thus affecting the probe's temperature detection and the accuracy of temperature measurement, the present invention is proposed.

This solves the problem that, due to the high-temperature gas passing through the turbine and the probe's lower temperature compared to the steam, water droplets condense on the probe's sidewall, affecting temperature detection and measurement accuracy. The invention effectively absorbs water from the probe's sidewall, ensuring accurate temperature measurement. Attached Figure Description

Detailed Implementation

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an 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 phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0030] Example 1

[0031] Referring to Figures 1-5, this is the first embodiment of the present invention. This embodiment provides a turbine cylinder monitoring device that can wipe water off the probe 104 to ensure accurate temperature measurement by the probe 104. It includes a support component 100, comprising a cylinder body 101, a temperature sensor 102 mounted on the cylinder body 101, a pressure sensor 103 mounted on the cylinder body 101, and a probe 104 mounted on the temperature sensor 102; and a wiping component 200, comprising a water collection assembly 201 disposed within the cylinder body 101, and... The water-absorbing component 202 is disposed on the water-collecting component 201; the one-way wiping component 300 includes a support component 301 disposed on the water-collecting component 201 and a guide component 302 disposed on the support component 301; the water-squeezing component 400 includes a squeezing component 401 disposed on the support component 301, a guide component 402 disposed on the squeezing component 401, a sealing component 403 disposed on the probe 104, a positioning component 404 disposed on the sealing component 403, and an elastic component 405 disposed on the positioning component 404.

[0032] Specifically, temperature sensor 102 can measure temperature changes in cylinder body 101. When cylinder body 101 leaks or has other problems, causing its temperature to drop, monitoring the temperature changes can determine whether cylinder body 101 is in normal working condition or a potential faulty state. Pressure sensor 103 can measure internal pressure changes in cylinder body 101. When cylinder body 101 wears or has other problems, its sealing performance may be affected, leading to internal pressure changes. Monitoring the temperature changes in cylinder body 101 can help determine whether cylinder body 101 is in normal working condition or a potential faulty state. Changes in internal pressure can assess the sealing performance and operating status of the cylinder body 101. Temperature sensor 102 and pressure sensor 103 can then detect the lifespan of the cylinder body 101. In use, the probe 104 of temperature sensor 102 is inserted into the cylinder body 101, with a distance maintained between the probe 104 and the turbine impeller to prevent collision between the impeller and the probe 104. Both temperature sensor 102 and pressure sensor 103 are equipped with instrument panels that display pressure and temperature values.

[0033] Furthermore, the water collection assembly 201 includes an L-shaped mounting ring 201a disposed on the outside of the probe 104. The lower end of the L-shaped mounting ring 201a is fixedly connected to a first water guide ring 201b. The cross-section of the first water guide ring 201b is oblique. The first water guide ring 201b and the L-shaped mounting ring 201a form a water collection area 201c. A water guide pipe 201d is provided in the water collection area 201c. The L-shaped mounting ring 201a is elastically connected to the inner wall of the cylinder body 101 by a first spring 201e. The water absorption assembly 202 includes a second water guide ring 202a fixedly connected to the side wall of the first water guide ring 201b. An arc-shaped water-absorbing cotton 202b is provided on the second water guide ring 202a.

[0034] It should be noted that the vertical side length of the L-shaped mounting ring 201a is designed to the required height during the design process, thereby adjusting the height and volume of the water collection section 201c to prevent water from flowing out of the water collection section 201c. At the same time, the water guide pipe 201d extends to the outside of the cylinder body 101 (a hole is provided on the cylinder body 101 to allow the passage of the water guide pipe 201d; the water guide pipe 201d is a common technology in the prior art and will not be described in detail here). The cross-section of the second water guide ring 202a is also oblique, and the second water guide ring 202a is higher on the left and lower on the right, which facilitates the guidance of water and makes it easier for water to flow to the water collection section 201c.

[0035] During use, when there is no need to absorb water from probe 104, the first spring 201e is energized and compressed (after being energized, the two turns of the first spring 201e attract each other, causing the length of the first spring 201e to shorten; this is existing technology and will not be elaborated here). After the cylinder body 101 has been running for a period of time, water droplets will condense on probe 104. At this time, the first spring 201e is de-energized (here, the de-energization process of the first spring 201e involves a continuous decrease in current until the current is cut off, thus preventing condensation). (In the case where the first spring 201e continues to reset), when the first spring 201e extends, it can drive the L-shaped mounting ring 201a to move downward. When the L-shaped mounting ring 201a moves downward, it can drive the first water-guiding ring 201b and the second water-guiding ring 202a to move downward, thereby driving the absorbent cotton 202b to move downward. When the absorbent cotton 202b moves downward, it abuts against the side wall of the probe 104 to absorb water on the side wall of the probe 104, thus preventing water from affecting the temperature measurement.

[0036] In summary, by switching the first spring 201e on and off, the absorbent cotton 202b can move up and down. When the absorbent cotton 202b moves downward, it can absorb the water on the side wall of the probe 104, thus preventing the water on the side wall of the probe 104 from affecting the temperature measurement of the probe 104 and ensuring the accuracy of the temperature measurement.

[0037] Example 2

[0038] Referring to Figures 3-6, this is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a one-way water-wiping assembly 300 for a steam turbine cylinder monitoring device, solving the problem of how to perform one-way water wiping and prevent water from being applied to the sidewall of the probe 104. It includes a support assembly 301, comprising multiple L-shaped plates 301a fixedly connected to an L-shaped mounting ring 201a. Each L-shaped plate 301a has a first guide groove 301b, a second guide groove 301c on the first guide groove 301b, a third guide groove 301d on the second guide groove 301c, a fourth guide groove 301e on the third guide groove 301d, a fifth guide groove 301f connected to the fourth guide groove 301e, and a sixth guide groove 301g connected to the fifth guide groove 301f. A concave point is formed between the fourth guide groove 301e and the fifth guide groove 301f. All grooves 301f are inclined, and the slope of the fourth guide groove 301e is greater than that of the fifth guide groove 301f. A baffle 301h is provided inside the first guide groove 301b, and the baffle 301h is elastically connected to the inner wall of the first guide groove 301b through a second spring 301i. The guide assembly 302 includes a cylinder 302a disposed at a concave point, and an arc plate 302b is fixedly connected to the lower end of each of the multiple cylinders 302a. The absorbent cotton 202b and the arc plate 302a are connected to each other. 2b is fixedly connected. A first top block 302c is fixedly connected to the arc plate 302b. The upper and lower ends of the first top block 302c are provided with a first inclined edge 302d. The inner side of the multiple first top blocks 302c is provided with a pair of second top blocks 302e that cooperate with the first top blocks 302c. The second top blocks 302e are provided with a second inclined edge 302f that cooperates with the first inclined edge 302d. The pair of second top blocks 302e are respectively set at the upper and lower ends of the probe 104.

[0039] Specifically, the second guide groove 301c is inclined, and the third guide groove 301d and the fourth guide groove 301e both serve as guides. When the cylinder 302a engages with the concave point, they can prevent the cylinder 302a from resetting. The slope of the fourth guide groove 301e is greater than the slope of the fifth guide groove 301f, so that the cylinder 302a resets from the fifth guide groove 301f and does not return to the fourth guide groove 301e. The sixth guide groove 301g is connected to the first guide groove 301b, so that the cylinder 302a can circulate. The first top block 302c is provided with a first inclined edge 302d on both the top and bottom. The second inclined edges 302f on a pair of second top blocks 302e are arranged opposite each other.

[0040] In use, when the L-shaped mounting ring 201a moves downward, it drives the arc-shaped plate 302b downward. When the arc-shaped plate 302b reaches its lower end, the absorbent cotton 202b contacts the lower end of the probe 104. At this time, the first inclined side 302d of the first top block 302c engages with the second inclined side 302f of the lower second top block 302e, causing the arc-shaped plate 302b to move outward. The telescopic spring 302h is compressed, and when the arc-shaped plate 302b moves, it drives the cylinder 302a to move, causing the cylinder 302a to move from the second guide groove 301c to the third guide groove 301d, and then to the concave point of the fourth guide groove 301e and the fifth guide groove 301f. When the L-shaped mounting ring 201a moves upward, the first top block 302c disengages from the lower second top block 302e. At this time, the cylinder 302a is stuck in the concave point, blocking the cylinder. When column 302a resets, and L-shaped mounting ring 201a moves upward, the cylinder 302a and arc plate 302b do not reset, resulting in a gap between absorbent cotton 202b and the side wall of probe 104. When moving upward, it does not absorb water, avoiding contact with the side wall of probe 104 and thus preventing water from being applied to it. When L-shaped mounting ring 201a moves to the upper end, the first inclined edge 302d at the upper end of the first top block 302c engages with the second inclined edge 302f at the lower end of the second top block 302e, causing the arc plate 302b to move outward. Since the slope of the fourth guide groove 301e is greater than the slope of the fifth guide groove 301f, the cylinder 302a resets from the fifth guide groove 301f and then resets to its original position via the sixth guide groove 301g. Thus, when moving downward, it can contact the side wall of probe 104 again, achieving the water absorption effect.

[0041] In summary, when the L-shaped mounting ring 201a moves downward, the absorbent cotton 202b can absorb water. When the L-shaped mounting ring 201a moves upward, the absorbent cotton 202b separates from the probe 104 and will not come into contact with the probe 104, thus preventing water from being wiped back onto the probe 104 and ensuring that the probe 104 remains dry. This further prevents water from getting on the probe 104 and affecting the detection.

[0042] Example 3

[0043] Referring to Figures 3-7, this is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a water-squeezing component 400 for a steam turbine cylinder monitoring device, solving the problem of how to squeeze water out of the absorbent cotton 202b. It includes a squeezing assembly 401, comprising a mounting port 401a on an L-shaped plate 301a, a first rotating shaft 401b rotatably connected within the mounting port 401a, a first torsion spring 401c mounted on the first rotating shaft 401b, and a connecting element fixedly connected to the first rotating shaft 401b. The adapter plate 401d has a receiving port 401e, and a second rotating shaft is rotatably connected inside the receiving port 401e. A roller 401f is fixedly connected to the second rotating shaft. The guide assembly 402 includes a first guide ring 402a fixedly connected to the side wall of the probe 104. A second guide ring 402b is fixedly connected to the first guide ring 402a. The diameter of the second guide ring 402b increases from bottom to top. The roller 401f cooperates with the side walls of the first guide ring 402a and the second guide ring 402b.

[0044] Specifically, the outer edge of the roller 401f extends to the outer side of the adapter plate 401d, so that when the outer edge of the roller 401f abuts against the first guide ring 402a, the adapter plate 401d and the first guide ring 402a will not get stuck. The diameter of the second guide ring 402b increases from bottom to top, which can cause the adapter plate 401d to deflect so as to squeeze water. The distance that the adapter plate 401d moves inward is greater than the length of the sixth guide groove 301g.

[0045] Furthermore, the sealing component 403 includes a sealing ring 403a fixedly connected to the side wall of the probe 104, the sealing ring 403a cooperating with the second water guide ring 202a, and an annular groove 403b provided on the inner wall of the sealing ring 403a; the positioning component 404 includes a slot 404a provided on the inner wall of the annular groove 403b, a third rotating shaft 404b rotatably connected in the slot 404a, a second torsion spring 404c provided on the third rotating shaft 404b, the third rotating shaft 404b fixedly connected to the second top block 302e, an electromagnet 404d fixedly connected to the bottom of the annular groove 403b, and an L-shaped magnetic ring 404e cooperating with the electromagnet 404d slidably connected in the annular groove 403b; the elastic component 405 includes a lifting ring 405a fixedly connected to the L-shaped magnetic ring 404e, and the lifting ring 405a elastically connected to the first guide ring 402a through the third spring 405b.

[0046] It should be noted that the outer edge of the sealing ring 403a is flush with the outer wall of the second water-guiding ring 202a, and a sealing gasket is provided on the side wall of the sealing ring 403a and the second water-guiding ring 202a, so that a sealing effect can be achieved when the sealing ring 403a and the second water-guiding ring 202a abut. When the electromagnet 404d is energized, it will repel the L-shaped magnetic ring 404e. When the L-shaped magnetic ring 404e abuts the second top block 302e, the second torsion spring 404c is in a compressed state, the electromagnet 404d is in an energized state, and the third spring 405b is compressed. Here, the lifting ring 405a is slidably connected to the side wall of the probe 104.

[0047] In use, the first spring 201e is energized and contracts (the reason has been explained above), the L-shaped mounting ring 201a faces upward, and when the first top block 302c abuts against the second top block 302e, the roller 401f abuts against the side wall of the first guide ring 402a. At this time, the cylinder 302a is in the second guide groove 301c and abuts against the baffle 301h. Then, the electromagnet 404d is de-energized, the repulsive force between the electromagnet 404d and the L-shaped magnetic ring 404e is eliminated, and under the action of the third spring 405b, the L-shaped magnetic ring 404e moves downward, causing the L-shaped magnetic ring 404e to abut against the second top block 302e. When blocks 302e separate, under the action of the second torsion spring 404c, the second top block 302e deflects, changing from horizontal to inclined. At this point, it does not obstruct the upward movement of the first top block 302c, and it does not push the first top block 302c downwards. Then, the L-shaped mounting ring 201a continues to move upwards, causing the roller 401f to abut against the side wall of the second guide ring 402b. Since the diameter of the second guide ring 402b increases sequentially from bottom to top, the adapter plate 401d deflects clockwise (from the side facing the L-shaped plate 301a). (Observed from the direction), the lower end of the adapter plate 401d deflects, causing it to change from an inclined position to a horizontal position. During this process, the arc-shaped plate 302b is pushed towards the sealing ring 403a. At this time, the cylinder 302a slides in the first guide groove 301b for guidance. As the arc-shaped plate 302b moves towards the sealing ring 403a, it can squeeze the absorbent cotton 202b between the sealing ring 403a and the arc-shaped plate 302b, squeezing out the water inside the absorbent cotton 202b. The squeezed-out water enters the water collection area under the guidance of the second water-guiding ring 202a and the first guide ring 402a. The water is discharged through the water pipe 201d within the space 201c, and will not accumulate inside the cylinder body 101. At the same time, because the water in the absorbent cotton 202b is squeezed out, the absorbent cotton 202b can continue to absorb water, ensuring the continuous water absorption effect of the absorbent cotton 202b. When the arc plate 302b moves, the cylinder 302a pushes the baffle 301h to move, avoiding the phenomenon of the cylinder 302a getting stuck. Moreover, the setting of the second spring 301i can reset the baffle 301h when the adapter plate 401d does not abut against the second guide ring 402b, so that the cylinder 302a and the arc plate 302b are reset.

[0048] In summary, by setting up the water-squeezing component 400, the electromagnet 404d is de-energized, and the adapter plate 401d is moved through transmission, causing the absorbent cotton 202b to be squeezed between the sealing ring 403a and the arc plate 302b, squeezing out the water inside the absorbent cotton 202b, ensuring the continuous water absorption effect of the absorbent cotton 202b, and ensuring the cleaning effect of the water on the probe 104.

[0049] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape, and proportions of various elements, as well as parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application).
