Description

Technical Field

[0001] This invention relates to the field of gas turbine enclosures, and more particularly to a video monitoring system for gas turbine enclosures. Background Technology

[0002] A gas turbine is an internal combustion power machine that uses a continuously flowing gas as a working fluid to drive a high-speed rotating impeller, converting the energy of fuel into useful work. It is a type of rotating impeller thermal engine. The gas turbine enclosure refers to a specially designed, quick-installation outer shell assembly of the gas turbine with capabilities such as sound insulation, heat insulation, impact resistance, and pollution resistance.

[0003] To better monitor the operating status of the gas turbine, sensors and cameras are usually installed inside the gas turbine enclosure. The cameras are installed on the upper side wall or top of the gas turbine enclosure.

[0004] For large gas turbines, such as the GTD25000 gas turbine which is 2.7 meters high, the installation height of the camera mounted on the upper side of the gas turbine casing is usually higher than 2.7 meters. Therefore, during subsequent maintenance of the camera, the disassembly and assembly of the camera requires the use of climbing equipment, which is troublesome.

[0005] Therefore, it is necessary to provide a video monitoring system for the gas turbine enclosure to solve the above-mentioned technical problems. Summary of the Invention

[0006] This invention provides a video monitoring system for the gas turbine enclosure, which solves the problem that the installation and removal of cameras installed on the upper side of the gas turbine enclosure during subsequent maintenance requires the use of climbing equipment, which is cumbersome.

[0007] To solve the above-mentioned technical problems, the present invention provides a video monitoring system for a gas turbine enclosure, comprising: an enclosure;

[0008] A horizontal adjustment mechanism is provided on the upper and lower sides of the side wall of the box body;

[0009] A monitoring mechanism, wherein the monitoring mechanism is connected to the horizontal adjustment mechanism via a locking mechanism;

[0010] Two air-cooled pipes, each with an air outlet at its upper and lower ends, and a first guide door and a second guide door connected to the two air outlets on the air-cooled pipes respectively via a rotating component.

[0011] The transmission mechanism includes two connecting plates, a support shaft, gears, a toothed belt, and two sets of sliding rods. The two sets of sliding rods are respectively suspended at the upper and lower ends of the air-cooling pipe. The two connecting plates are slidably connected to the two sets of sliding rods. The two support shafts are rotatably connected to the two connecting plates. The two gears are respectively connected to the two support shafts. The two ends of the toothed belt are respectively sleeved on the two gears. The two support shafts are respectively plugged and unplugged connected to the two rotating parts.

[0012] A carrier component, which is connected to the toothed belt;

[0013] An electric motor is connected to the connecting plate, and the output shaft of the motor is connected to a support shaft;

[0014] When the transmission mechanism functions as an angle adjustment mechanism, the motor drives one of the support shafts to rotate clockwise or counterclockwise, and through the gear and the toothed belt, drives the other support shaft to rotate, thereby driving the two rotating parts to rotate and realize the opening and closing of the first guide door and the second guide door. When the transmission mechanism functions as a lifting mechanism, i.e., when it is necessary to remove the monitoring mechanism located on the upper side inside the box body, the support shaft is moved to separate from the rotating parts, the locking mechanism unlocks the monitoring mechanism, and the monitoring mechanism falls onto the carrier. At this time, the motor drives the toothed belt to move the carrier downward, making it easier to remove the monitoring mechanism located on the upper side inside the box body.

[0015] Preferably, the rotating component includes a fixed ear and a rotating shaft. The fixed ear is fixed to the air-cooling pipe, and the rotating shaft is rotatably connected to the fixed ear.

[0018] Preferably, the locking mechanism includes a mounting frame, a insert shaft, a push plate, an elastic element, and a drive unit. The mounting frame is mounted on the horizontal adjustment mechanism. The insert shaft passes through the mounting frame. The push plate is fixed to the insert shaft. The elastic element is sleeved on the insert shaft and located between the push plate and the mounting frame. The mounting frame has a slot. The insert block passes through the slot and is inserted into the insert shaft. The drive unit includes a push arm and a transmission arm. The push arm is fixed to a connecting plate located at the upper end of the air-cooling pipe. The transmission arm is fixed to the push plate. When the monitoring mechanism is located at the end of the horizontal adjustment mechanism closer to the transmission mechanism, the push arm connects with the transmission arm.

[0019] Preferably, the carrier includes a carrier plate and a convex shaft. The carrier plate is fixed on the toothed belt and sleeved on the connecting arm. The fixed plate has a strip hole. When the locking mechanism unlocks the monitoring mechanism and the monitoring mechanism falls onto the carrier plate, the strip hole is sleeved on the convex shaft.

[0020] Preferably, the video monitoring system inside the gas turbine housing further includes an axial positioning component, which includes a connecting frame, a positioning shaft, a positioning disc, and positioning holes. One end of the connecting frame is fixed to the connecting plate, the positioning shaft is fixed to the other end of the connecting frame, the positioning disc is fixed to the rotating shaft, and the positioning disc has multiple positioning holes.

[0021] Preferably, the horizontal adjustment mechanism includes a horizontal drive mechanism, a slide rail, and a slider.

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0049] This invention provides a video monitoring system for the interior of a gas turbine enclosure.

[0050] Please refer to the following: Figures 1 to 4 In one embodiment of the present invention, the video monitoring system inside the gas turbine enclosure includes: enclosure 1;

[0051] A horizontal adjustment mechanism 3 is provided on the upper and lower sides of the side wall of the box body 1;

[0052] Monitoring mechanism 5, which is connected to the horizontal adjustment mechanism 3 via a locking mechanism 4;

[0053] Two air-cooled pipes 2, each with an air outlet 21 at its upper and lower ends, and a first guide door 62 and a second guide door 63 connected to the two air outlets 21 on the air-cooled pipes 2 respectively via a rotating component 61.

[0054] The transmission mechanism 8 includes two connecting plates 82, a support shaft 83, a gear 84, a toothed belt 85, and two sets of sliding rods 81. The two sets of sliding rods 81 are respectively suspended at the upper and lower ends of the air-cooled pipe 2. The two connecting plates 82 are slidably connected to the two sets of sliding rods 81. The two support shafts 83 are rotatably connected to the two connecting plates 82. The two gears 84 are respectively connected to the two support shafts 83. The two ends of the toothed belt 85 are respectively sleeved on the two gears 84. The two support shafts 83 are respectively plugged and unplugged connected to the two rotating parts 61.

[0055] The carrier 9 is connected to the toothed belt 85;

[0056] Motor 7, the motor 7 is connected to the connecting plate 82, and the output shaft of the motor 7 is connected to a support shaft 83;

[0057] When the transmission mechanism 8 is used for angle adjustment, the motor 7 drives one of the support shafts 83 to rotate clockwise or counterclockwise. Through the gear 84 and the toothed belt 85, the other support shaft 83 is driven to rotate, thereby driving the two rotating parts 61 to rotate, realizing the opening and closing of the first guide door 62 and the second guide door 63. When the transmission mechanism 8 is used for lifting, that is, when it is necessary to remove the monitoring mechanism 5 located on the upper side inside the box body 1, the support shaft 83 is moved to separate from the rotating parts 61, the locking mechanism 4 unlocks the monitoring mechanism 5, and the monitoring mechanism 5 falls onto the carrier 9. At this time, the motor 7 drives the toothed belt 85 to move the carrier 9 down, making it easier to remove the monitoring mechanism 5 located on the upper side inside the box body 1.

[0058] The transmission mechanism 8 inside the gas turbine housing 1 is used to adjust the opening and closing of the first guide door 62 and the second guide door 63 on the upper and lower sides of the air-cooled pipe 2. By adjusting the position of the transmission mechanism 8, the monitoring mechanism 5 is used to move from the upper side to the lower side of the side wall of the housing 1. With the help of the locking mechanism 4, it is convenient to disassemble and install the monitoring mechanism 5 without the need for additional climbing equipment.

[0059] The motor 7 is preferably connected to the support shaft 83 located on the lower side.

[0060] The interior of the enclosure 1 is equipped with an air-cooled pipe 2. The air-cooled pipe 2 is connected to a cold air blower through the air outlets 21 on the upper and lower sides of the air-cooled pipe 2, and the cold air is distributed in multiple different spaces on the upper and lower sides of the enclosure 1 to improve the temperature distribution inside the enclosure 1, reduce the temperature of key parts, and ensure the safe operation of the equipment inside the enclosure 1.

[0061] Furthermore, the outlets of the two symmetrically arranged air-cooled pipes 2 are directed towards the gas turbine, allowing the cooling air to be more effectively applied to the gas turbine. Please refer to [link / reference needed]. Figure 8 Meanwhile, a first guide door 62 and a second guide door 63 are provided on the air outlet 21. After the first guide door 62 and the second guide door 63 are opened, the first guide door 62 and the second guide door 63 can guide the cold air, so that the cold air flows better to the gas turbine and improves the cooling effect. The bottom of the air outlet located on the lower side of the housing 1 is inclined, and the second guide door 63 is preferably parallel to it after it is opened. The angle of the first guide door 62 and the second guide door 63 can be adjusted as needed to change the direction of airflow.

[0062] Please see Figure 3 and Figure 4 The rotating component 61 includes a fixed ear 611 and a rotating shaft 612. The fixed ear 611 is fixed to the air-cooling pipe 2, and the rotating shaft 612 is rotatably connected to the fixed ear 611. A square groove 613 is provided at one end of the rotating shaft 612 facing the support shaft 83. A rectangular block 831 is connected to one end of the support shaft 83 facing the rotating shaft 612. The rectangular block 831 is inserted into the square groove 613, and the sliding rod 81 is fixed to the fixed ear 611.

[0063] By creating a square groove 613 on the rotating shaft 612 to engage with the rectangular block 831 on the rotating shaft 612, when it is necessary to remove the monitoring mechanism 5 located on the upper side of the side wall of the housing 1, the position of the transmission mechanism 8 is adjusted so that the connecting plate 82 slides along the slide rod 81 away from the rotating shaft 612, thereby causing the support shaft 83 to separate from the rotating shaft 612 and the rectangular block 831 to separate from the square groove 613. At this time, the motor 7 drives the gear 84 to rotate counterclockwise, thereby driving the toothed belt 85 to move the bearing 9 downward, and transporting the monitoring mechanism 5 after the locking mechanism 4 is unlocked from the upper side wall of the housing 1 to the lower side, without the need to set up climbing equipment.

[0064] Each rotating component 61 includes two fixed ears 611, and the two ends of the rotating shaft 612 are rotatably connected to the two fixed ears 611 respectively. Each set of slide rods 81 consists of two rods, which are connected to the fixed ears 611 on the side closer to the motor 7.

[0065] As a preferred embodiment, the two connecting plates 82 are connected by a connecting arm 86.

[0066] By connecting the two connecting plates 82 through the connecting arm 86, when the lower connecting plate 82 is moved, the connecting arm 86 more stably drives the upper connecting plate 82 to move along with it, so that the rectangular block 831 at the end of the support shaft 83 moves out of or into the square groove 613 at the end of the rotating shaft 612. Preferably, two connecting arms 86 are provided.

[0067] Please refer to it again. Figure 3 The monitoring mechanism 5 includes a fixing plate 51, a plug 52 and a camera 54. The camera 54 is installed at the bottom of the fixing plate 51, the plug 52 is fixed at the top of the fixing plate 51, and the plug 52 has a plug hole. The output end of the locking mechanism 4 is plugged into the plug hole.

[0068] By setting the plug 52 to be plugged into the output end of the locking mechanism 4, when the output end of the locking mechanism 4 is retracted, it can be separated from the plug 52, that is, the camera 54 is separated from the locking mechanism 4, so that it can fall on the carrier 9, which makes it easy to disassemble and unlock the monitoring mechanism 5.

[0069] In this embodiment, the locking mechanism 4 includes a mounting frame 41, a telescopic cylinder, and a fixed shaft. The telescopic cylinder is mounted on the mounting frame 41, and the fixed shaft is connected to the output end of the telescopic cylinder. A slot 45 is provided on the mounting frame 41, and the insertion block 52 passes through the slot 45. The telescopic cylinder pushes the fixed shaft into the insertion hole for insertion and fixation. The telescopic cylinder can be a pneumatic cylinder, a hydraulic cylinder, or an electric telescopic cylinder. The camera 54 is preferably a camera 54 that can be adjusted for both horizontal and vertical angles.

[0070] Please refer to it again. Figure 3 In a preferred embodiment, the locking mechanism 4 includes a mounting frame 41, a insert shaft 42, a push plate 43, an elastic element 44, and a drive unit 12. The mounting frame 41 is mounted on the horizontal adjustment mechanism 3. The insert shaft 42 passes through the mounting frame 41. The push plate 43 is fixed to the insert shaft 42. The elastic element 44 is sleeved on the insert shaft 42 and located between the push plate 43 and the mounting frame 41. The mounting frame 41 has a slot 45. The insert block 52 passes through the slot 45 and is inserted into the insert shaft 42. The drive unit 12 includes a push arm 121 and a transmission arm 122. The push arm 121 is fixed to the connecting plate 82 located at the upper end of the air-cooling pipe 2. The transmission arm 122 is fixed to the push plate 43. When the monitoring mechanism 5 is located at the end of the horizontal adjustment mechanism 3 near the transmission mechanism 8, the push arm 121 contacts the transmission arm 122.

[0071] When the position of the connecting plate 82 is adjusted to separate the rectangular block 831 from the square groove 613, and when the transmission mechanism 8 is adjusted for lifting function, pulling the connecting plate 82 causes the rectangular block 831 at the end of the support shaft 83 to separate from the square groove 613 at the end of the rotating shaft 612. At the same time, the connecting plate 82 drives the push arm 121 to move to one side of the horizontal adjustment mechanism 3. The push arm 121 pushes the transmission arm 122, and the transmission arm 122 drives the push plate 43 to move and compress the elastic element 44. The push plate 43 drives the end of the insertion shaft 42 to move out of the insertion block 52. At this time, the monitoring mechanism 5 can fall on the bearing member 9. There is no need to set up additional drive equipment such as telescopic cylinders, which saves energy and reduces costs.

[0072] Among them, the elastic element 44 is preferably a spring.

[0073] Please refer to it again. Figure 3 The carrier 9 includes a carrier plate 91 and a convex shaft 92. The carrier plate 91 is fixed on the toothed belt 85 and sleeved on the connecting arm 86. The fixing plate 51 has a strip hole 53. When the locking mechanism 4 unlocks the monitoring mechanism 5 and the monitoring mechanism 5 falls onto the carrier plate 91, the strip hole 53 is sleeved on the convex shaft 92.

[0074] By setting the convex shaft 92 to cooperate with the strip hole 53 on the fixing plate 51, when the monitoring mechanism 5 falls on the bearing plate 91, the strip hole 53 is fitted on the convex shaft 92, so that the bearing component 9 can transport the camera 54 more stably.

[0075] Among them, after the strip hole 53 on the fixed plate 51 is fitted onto the convex shaft 92 on the bearing plate 91, the bearing plate 91 is provided with a support plate surface facing the fixed plate 51, which can support the fixed plate 51 at the same time, and together with the convex shaft 92, it provides stable support for the entire monitoring mechanism 5.

[0076] In this way, by fitting the bearing plate 91 onto the connecting arm 86, the bearing plate 91 can move down along the connecting arm 86 as it moves down with the toothed belt 85. The connecting arm 86 limits its movement, allowing the bearing plate 91 to move down or up stably and preventing it from shifting.

[0077] The convex shaft 92 is preferably a square shaft, and a rubber sleeve is provided on its surface to improve the stability after insertion into the strip hole 53. The length of the strip hole 53 is longer than the thickness of the convex shaft 92, and the difference is not less than the length of the rectangular block 831.

[0078] Please refer to again Figure 3 and Figure 4 The video monitoring system inside the gas turbine enclosure also includes an axial positioning component 10. The axial positioning component 10 includes a connecting frame 101, a positioning shaft 102, a positioning disk 103, and positioning holes 104. One end of the connecting frame 101 is fixed to the connecting plate 82, the positioning shaft 102 is fixed to the other end of the connecting frame 101, the positioning disk 103 is fixed to the rotating shaft 612, and the positioning disk 103 has multiple positioning holes 104.

[0079] By setting the axial positioning component 10, when the air-cooled pipe 2 continuously delivers cold air while the gas turbine is in operation, and the camera 54 needs to be inspected, when the transmission mechanism 8 is adjusted from the angle adjustment function to the lifting function, the connecting plate 82 can be adjusted to drive the connecting frame 101 to move accordingly. The connecting frame drives the positioning shaft 102 to be inserted into the positioning hole 104 on the positioning plate 103, axially positioning the rotating shaft 612, that is, axially limiting the first guide door 62 and the second guide door 63, so as to prevent the first guide door 62 and the second guide door 63 from rotating downward due to gravity and affecting the flow of cold air after the first guide door 62 and the second guide door 63 are not axially limited by the motor 7.

[0080] Specifically, when the first guide door 62 and the second guide door 63 are closed and opened, respectively, the positioning holes 104 on the positioning disk 103 are aligned with the positioning shaft 102. There are at least two positioning holes 104. The output shaft of the motor 7 has a self-locking function.

[0081] Please see Figures 1 to 3 The horizontal adjustment mechanism 3 includes a horizontal drive mechanism 31, a slide rail 32, and a slider 33. The horizontal drive mechanism 31 is fixed to the side wall of the box body 1. The slide rail 32 is installed on the side wall of the box body 1 and located below the horizontal adjustment mechanism 3. The slider 33 is slidably connected to the slide rail 32. The mounting bracket 41 is installed on the slider 33.

[0082] The horizontal drive mechanism 31 can adjust the position of the slider 33 on the slide rail 32, thereby adjusting the position of the monitoring mechanism 5 and delivering the camera 54 to the desired monitoring position.

[0083] The slide rail 32 is preferably configured as two slide arms, and the slider 33 is sleeved on the slide arms to form a sliding fit.

[0084] The horizontal drive mechanism 31 can be a belt conveyor, a chain conveyor, or a screw conveyor, preferably a belt conveyor, and the slider 33 is connected to the conveyor belt through a connector.

[0085] In a preferred embodiment, two sets of the horizontal adjustment mechanism 3 are provided, and the two sets of horizontal adjustment mechanisms 3 are symmetrically arranged on the side wall of the box body 1. Each set of horizontal adjustment mechanisms 3 consists of two parts, which are respectively arranged on the upper and lower sides of the side wall of the box body 1. Each horizontal adjustment mechanism 3 is provided with a monitoring mechanism 5.

[0086] Please see Figure 2 Four monitoring units 5 are respectively set on the two long side walls of the container 1, and are staggered vertically. The camera 54 in the monitoring unit 5 located on the lower side monitors from an upward angle, while the camera 54 in the monitoring unit 5 located on the upper side monitors from a downward angle.

[0087] The position of the monitoring mechanism 5 can be adjusted via the horizontal adjustment mechanism 3, allowing for monitoring adjustments as needed.

[0088] The locking mechanism 4 on the horizontal adjustment mechanism 3 located below the side wall of the box body 1 has a transmission arm 122 in the push plate 43. When installing or removing the monitoring mechanism 5 installed on the horizontal adjustment mechanism 3 below the side wall, the position of the insertion shaft 42 is manually adjusted to assemble or separate from the insertion hole on the fixing plate 51.

[0089] In one embodiment, the camera 54 may have a built-in battery and a wireless module. The battery is used to ensure the normal operation of the camera 54 and the wireless module, and the wireless module is used to transmit the monitoring data of the camera 54 to the outside world.

[0090] In another embodiment, the camera 54 can also be powered by connecting to a power source via a power cord. Furthermore, the camera 54 can also transmit monitoring data to a hard disk recorder via a communication cable through a switch, and then the hard disk recorder transmits the data to a display device for display. Both the power cord and the communication cable are detachably connected to the camera 54 via plugs.

[0091] The communication cable, located inside the enclosure 1, is provided with sufficient length to allow the monitoring mechanism 5 to be transported from the upper side of the side wall of the enclosure 1 to the lower side wall of the enclosure 1 via the transmission mechanism 8, while also allowing the monitoring mechanism 5 to adjust its movement distance along the horizontal adjustment mechanism 3. When a power cord is used for power supply, the length of the power cord is the same as that of the communication cable, and the surfaces of the communication cable and the power cord are preferably covered with heat insulation sleeves.

[0092] The working principle of the video monitoring system inside the gas turbine enclosure provided by this invention is as follows:

[0093] When the transmission mechanism 8 is used for angle adjustment, the motor 7 drives the lower support shaft 83 to rotate clockwise. The gear 84 and the toothed belt 85 then drive the upper support shaft 83 to rotate simultaneously. The two support shafts 83 drive the two rotating shafts 612 to rotate, thereby rotating either the first guide door 62 or the second guide door 63, opening the two air outlets 21. The first guide door 62 and the second guide door 63 are opened to the desired angle. Figure 8 In the medium state, the airflow delivered from the air outlet 21 can be guided to the gas turbine 11, which has a better cooling effect; when the gas turbine 11 is not working, the motor 7 rotates counterclockwise, driving the first guide door 62 and the second guide door 63 to close.

[0094] The angles of the first guide gate 62 and the second guide gate 63 can be changed as needed to adjust the direction of airflow.

[0095] When the transmission mechanism 8 is used for lifting, the camera 54 located on the upper side of the side wall of the container body 1 needs to be inspected:

[0096] Please see Figure 6 First, the monitoring mechanism 5 to be disassembled is transported to one end near the air-cooling pipe 2 through the horizontal drive mechanism 31, so that the strip hole 53 on the fixing plate 51 corresponds to the convex shaft 92 on the bearing plate 91 (wherein the horizontal adjustment mechanism 3 adjusts the travel of the monitoring mechanism 5, preferably by program control).

[0097] When the first guide door 62 and the second guide door 63 are in the open state, the convex shaft 92 on the support plate 91 is located directly below the strip hole 53. When the first guide door 62 and the second guide door 63 are in the closed state, the motor 7 can be started to drive it to open, so that the convex shaft 92 moves up to directly below the strip hole 53.

[0098] Then, the connecting plate 82 is moved closer to the side of the horizontal adjustment mechanism 3. The connecting plate 82 moves along with the connecting arm 86, and the two connecting plates 82 move the rectangular block 831 at the end of the corresponding support shaft 83 out of the square groove 613 at the end of the rotating shaft 612. At the same time, the connecting plate 82 drives the push arm 121 to push the transmission arm 122. The transmission arm 122 pushes the push plate 43 to compress the elastic element 44 and causes the insertion shaft 42 to separate from the fixed plate 51. At this time, the monitoring mechanism 5 slides down under its own weight, the insertion block 52 slides down along the slot 45, and the strip hole 53 is fitted onto the convex shaft 92.

[0099] Please see Figure 7 The motor 7 is controlled to rotate counterclockwise, and the toothed belt 85 drives the bearing 9 to move down, thereby driving the monitoring mechanism 5 to move down to the bottom of the toothed belt 85. Then the monitoring mechanism 5 can be removed for inspection or replacement.

[0100] When the maintenance is completed or a new monitoring mechanism 5 is installed, the strip hole 53 on the fixing plate 51 of the monitoring mechanism 5 is once again fitted onto the cam shaft 92. The motor 7 rotates clockwise, and the toothed belt 85 drives the bearing 9 to move upward, thereby driving the monitoring mechanism 5 to move upward as well, until the insertion block 52 in the monitoring mechanism 5 passes through the slot 45 and the insertion hole on the insertion block 52 is aligned with the insertion shaft 42.

[0101] Then push the connecting plate 82 so that the rectangular block 831 at the end of the support shaft 83 is inserted into the slot 45 again, and the connecting plate 82 drives the push arm 121 to gradually move away from the transmission arm 122. Through the action of the elastic element 44, the push plate 43 is pushed, which drives the insertion shaft 42 to be inserted into the insertion hole on the insertion block 52 to fix the monitoring mechanism 5.

[0102] Then, the horizontal adjustment mechanism 3 can be used to move the monitoring mechanism 5 to the corresponding monitoring position.

[0103] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
