Abstract
Description
Technical Field
[0001] This application relates to the field of gas turbine technology, and in particular to a canopy for a gas turbine intake system. Background Technology
[0002] As a highly efficient power equipment, the stability of the gas turbine's intake system directly affects its operating efficiency and reliability. In the gas turbine's intake system, the canopy is an important protective device used to block rainwater, snowflakes, and other pollutants from entering the intake and prevent the filtration system from failing due to excessive humidity.
[0003] Existing awnings typically employ a multi-layered waterproof baffle combined with a rain-proof eave and drainage pipe. By setting a rain-proof eave on the front of the waterproof baffle, a water collection trough is formed by the concave cavity of the rain-proof eave, and rainwater from each layer is diverted to the ground through a vertical drainage pipe to achieve the rainproof function.
[0004] However, in actual operation, it was found that during windy and rainy weather, large impurities such as leaves and plastic from the external environment can easily fall directly into the recessed cavity of the rain shelter. The impurities accumulate inside the rain shelter and cannot be discharged, which can easily cause blockage of the drain outlet. At this time, rainwater cannot be discharged in time, the water level inside the rain shelter rises rapidly, and rainwater overflows to the outer wall of the rainproof baffle. In this case, the strong suction of the gas turbine air inlet may directly suck the accumulated water into the filter chamber, causing the gas turbine air intake system to malfunction, which is obviously insufficient. Utility Model Content
[0005] In order to improve the drainage efficiency of the rain shelter and reduce the possibility of rainwater overflow causing air intake system failure, this application provides a rain shelter for a gas turbine air intake system.
[0006] The technical solution for a canopy for a gas turbine intake system provided in this application is as follows:
[0007] A rain shelter for a gas turbine intake system includes a rainproof shell with multiple waterproof baffles evenly spaced on the shell. Each waterproof baffle has a rain-proof eave and a filter plate. The end of the filter plate away from the waterproof baffle is located on the rain-proof eave. The filter plate is used to prevent large debris from entering the rain-proof eave.
[0008] By adopting the above technical solution, during the operation of the gas turbine, the filter plate physically intercepts large debris such as leaves and plastic pieces, preventing large impurities from entering the water collection trough area inside the rain shelter. This avoids debris accumulating near the drain outlet and causing blockage, thus ensuring the smooth discharge of rainwater inside the rain shelter and effectively reducing the possibility of rainwater overflow causing intake system failure.
[0009] Optionally, the rain shield has a movable groove along its length, and a guide rod is provided in each movable groove. A movable block that slides through the guide rod and is slidably engaged with the movable groove is provided on the movable block. A cleaning rod is provided on the movable block and abuts against the surface of the filter plate. A drive assembly is provided on the rainproof shell to drive the cleaning rod to move along the length of the filter plate.
[0010] By adopting the above technical solution, the drive component drives the moving block to move the cleaning rod along the length of the filter plate. When the cleaning rod moves, it pushes the large impurities intercepted on the surface of the filter plate to the edge area of the filter plate, keeping the water passage in the center area of the filter plate unobstructed. This effectively avoids the possibility of rainwater infiltration difficulties due to filter plate pore blockage and ensures unobstructed drainage path of the rain shelter.
[0011] Optionally, the rainproof shell has a drive cavity, and the drive assembly includes a take-up roller rotatably connected in the drive cavity. A motor is provided in the drive cavity to drive the take-up roller to rotate. A pull rope corresponding to each of the multiple moving blocks is wound on the take-up roller. The free end of the pull rope extends into the moving groove and is disposed on the corresponding moving block. Each moving groove is provided with an elastic rope. One end of the elastic rope is disposed at the end of the moving groove away from the drive cavity, and the other end is disposed on the moving block. In the natural state of the elastic rope, the moving block is disposed at the end of the moving groove away from the drive cavity.
[0012] By adopting the above technical solution, during cleaning, the motor drives the take-up roller to rotate forward, which in turn drives the pull rope to wind up. At this time, the free end of the pull rope pulls the moving block towards the drive cavity, and the elastic rope is continuously tensioned. As the cleaning rod moves, it removes the impurities intercepted on the surface of the filter plate. When the cleaning rod moves to the end of the filter plate near the drive cavity, the motor drives the take-up roller to rotate in the opposite direction, and the take-up roller loosens the pull rope. The pull rope is continuously slack, and the elastic rope, under the action of elasticity, pulls the moving block to move away from the drive cavity. At this time, the cleaning rod further cleans the surface of the filter plate. This setting realizes the synchronous reciprocating motion of multiple cleaning rods along the surface of the filter plate, achieving synchronous cleaning of multiple filter plates, ensuring that the canopy effectively blocks debris and maintains efficient drainage function during long-term use.
[0013] Optionally, the rainproof shell has an impurity channel corresponding to each of the multiple waterproof baffles. The impurity channel is connected to the upper surface of the filter plate. The rainproof shell also has a waste area connected to the multiple impurity channels. The multiple impurity channels are all inclined from top to bottom along the direction close to the waste area. A waste door is hinged to the outer surface of the waste area.
[0014] By adopting the above technical solution, when the cleaning rod moves, it pushes the impurities on the surface of the filter plate into the impurity channel of the rainproof shell. Large impurities automatically slide down to the waste area along the impurity channel under the action of gravity. Workers can open the waste door periodically to clean the collected impurities. This setting realizes the centralized collection of impurities on the surface of the filter plate, avoiding the possibility of impurities being blown back to the surface of the filter plate by wind and rain, thereby further reducing the probability of filter plate clogging.
[0015] Optionally, the filter plate has raised strips on both sides, the waterproof baffle and the rainproof eaves are provided with grooves that slide with the raised strips, the rainproof shell is provided with a slot for sliding with the filter plate, the end of the filter plate is provided with a mounting plate, and the mounting plate is provided with a fixing component for fixing the filter plate above the rainproof eaves.
[0016] By adopting the above technical solution, when the filter plate needs to be replaced, the worker can remove the fixing function of the fixing component, and then pull the old filter plate out of the placement groove through the sliding cooperation of the convex strip and the groove, and slide the new filter plate into the rainproof shell. Finally, it is fixed by the fixing component. In this way, the filter plate can be replaced conveniently. Filter plates with different pore sizes can be replaced according to different usage environments. When the filter plate rusts due to rainwater corrosion, it can be replaced immediately, ensuring that the filter plate can intercept impurities.
[0017] Optionally, the mounting plate is provided with a fixing plate, and each of the opposite end faces of the fixing plate is provided with a guide post. A pin plate is slidably sleeved on the guide post. The rainproof shell is provided with a pin sleeve corresponding to each of the pin plates. The pin plate and the corresponding pin sleeve are inserted into each other. Each guide post is provided with a retaining spring on its outer surface. The elastic force of the retaining spring pushes the pin plate into the pin sleeve.
[0018] By adopting the above technical solution, when the filter plate needs to be removed, the worker overcomes the elastic force of the clamping spring to bring the two pin plates closer together. At this time, both pin plates are disengaged from the pin sleeves, the fixing effect of the fixing components disappears, and the worker pulls out the filter plate. When the new filter plate is installed in place, the worker releases the force on the pin plates. Under the guidance of the guide column, the elastic force of the clamping spring pushes the two pin plates to insert into the two pin sleeves respectively, thereby fixing the filter plate.
[0019] Optionally, each of the rain shelters is fitted with an electric heating strip.
[0020] By adopting the above technical solution, when the ambient temperature is below freezing, the electric heating belt actively heats the internal area of the rain shelter, effectively preventing rainwater from freezing inside the rain shelter and avoiding problems such as blockage of drainage channels or poor water flow caused by freezing. This further improves the drainage efficiency of the rain shelter and reduces the possibility of rainwater overflow causing air intake system failure.
[0021] Optionally, both the waterproof baffle and the rainproof eaves are coated with polytetrafluoroethylene (PTFE).
[0022] By adopting the above technical solution, the polytetrafluoroethylene coating has low surface energy characteristics, which significantly reduces the adhesion of large debris such as leaves and plastic to the surface of the waterproof baffle, making it easy for debris to be washed away by rain or removed from the surface of the waterproof baffle by natural wind. At the same time, the polytetrafluoroethylene coating can accelerate the flow rate of rainwater on the surface of the rain shelter, avoid the formation of water film or water droplet adsorption by rainwater retention, and ensure that the rain shelter can play a stable role in rain protection and anti-clogging function for a long time.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] This embodiment of the application sets up a filter plate, which physically intercepts large debris such as leaves and plastic pieces, preventing large impurities from entering the water collection trough area inside the rain shelter. This avoids debris accumulating near the drain outlet and causing blockage, thereby ensuring the smooth drainage of rainwater inside the rain shelter and effectively reducing the possibility of rainwater overflow causing air intake system failure.
[0025] This embodiment of the application sets up a cleaning rod and a driving component. The driving component drives the moving block to move the cleaning rod along the length of the filter plate. When the cleaning rod moves, it pushes the large impurities intercepted on the surface of the filter plate to the edge area of the filter plate, keeping the water channel in the center area of the filter plate unobstructed. This effectively avoids the possibility of rainwater infiltration difficulties due to the blockage of the filter plate pores, and ensures that the drainage channel of the rain shelter is unobstructed.

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0033] This application discloses a canopy for a gas turbine intake system.
[0034] Reference Figure 1 and Figure 2 A rain shelter for a gas turbine intake system includes a rainproof shell 1, which is installed at the intake end of the gas turbine. Multiple waterproof baffles 2 are evenly installed from top to bottom on the end face of the rainproof shell 1. The waterproof baffles 2 have an inclined drainage surface. A rain shield 3 is fixedly connected to the lower end of the inclined surface of each waterproof baffle 2. The inner cavity of the rain shield 3 forms a rain collection groove for collecting rainwater. The outer surfaces of the waterproof baffles 2 and the rain shield 3 are coated with polytetrafluoroethylene.
[0035] Reference Figure 1 and Figure 2 An electric heating belt (not shown in the figure) is fixedly embedded in the inner wall of the rain shelter 3. When the ambient temperature is below freezing, the electric heating belt heats the concave area of the rain shelter 3, effectively avoiding the problem of drainage channel blockage or water flow obstruction caused by freezing.
[0036] Reference Figure 1 and Figure 2 Each waterproof baffle 2 is provided with a filter plate 4, which is parallel to the length of the waterproof baffle 2. The rainproof shell 1 is provided with a placement groove 101 that slides with the filter plate 4. The waterproof baffle 2 and the rainproof eaves 3 are provided with grooves 21 that slide with the opposite sides of the filter plate 4. One end of the filter plate 4 is fixedly connected to an installation plate 41, and the installation plate 41 is provided with a fixing component 5 that fixes the filter plate 4 above the rainproof eaves 3.
[0037] The filter plate 4 is installed above the rain shelter 3 by sliding the filter plate 4 and the groove 21. At this time, the filter plate 4 forms a physical interception of large debris such as leaves and plastic pieces, preventing large impurities from entering the water collection trough area inside the rain shelter 3, avoiding the accumulation of debris near the drain outlet and causing blockage, thereby ensuring the smooth discharge of rainwater inside the rain shelter 3, and effectively reducing the possibility of rainwater overflow causing air intake system failure.
[0038] Reference Figure 2 and Figure 3 The fixing component 5 includes a fixing plate 51 fixedly installed on the surface of the mounting plate 41. The fixing plate 51 is located at the center of the mounting plate 41. Guide posts 52 are fixedly connected to the opposite end faces of the fixing plate 51. The guide posts 52 are parallel to the length direction of the mounting plate 41. A pin plate 53 is slidably sleeved on the outer surface of each guide post 52. A limiting ring (not shown in the figure) for limiting the maximum movement distance of the pin plate 53 is fixedly connected to the outer surface of each guide post 52. A pin sleeve 54 corresponding to each of the multiple pin plates 53 is fixedly connected to the rainproof shell 1. The pin plate 53 and the corresponding pin sleeve 54 are inserted and engaged. A clamping spring 55 is sleeved on the outer surface of each guide post 52. One end of the clamping spring 55 is fixedly connected to the surface of the fixing plate 51, and the other end is fixedly connected to the pin plate 53. The elastic force of the clamping spring 55 pushes the pin plate 53 to insert into the pin sleeve 54.
[0039] When a filter plate 4 needs to be replaced due to wear or specification, the worker overcomes the elastic force of the clamping spring 55 to bring the two pin plates 53 on the mounting plate 41 closer together. At this time, both pin plates 53 are disengaged from the pin sleeves 54, and the fixing effect of the fixing component 5 is lost. The worker pulls the filter plate 4 outward to detach it from the rainproof shell 1. After the new filter plate 4 is installed in place, the worker releases the force on the pin plates 53. Under the guidance of the guide post 52, the elastic force of the clamping spring 55 pushes the two pin plates 53 to insert into the two pin sleeves 54 respectively, thereby fixing the filter plate 4. This achieves convenient replacement of the filter plate 4. Filter plates 4 with different pore sizes can be replaced according to different usage environments. When the filter plate 4 rusts due to rainwater corrosion, it can be replaced immediately, ensuring that the filter plate 4 intercepts impurities.
[0040] Reference Figure 3 and Figure 4 The rain shield 3 has a movable groove 6 along its length. A guide rod 61 is fixedly connected in each movable groove 6. A movable block 62 that slides on the guide rod 61 and is in sliding cooperation with the movable groove 6 is slidably mounted on the movable block 62. A cleaning rod 63 is fixedly connected to the movable block 62 and abuts against the surface of the filter plate 4.
[0041] Reference Figure 3 and Figure 4A drive cavity 102 is provided in the side wall of one end of the rainproof shell 1. The drive cavity 102 is vertically arranged and a drive assembly 7 is provided in the drive cavity 102. Specifically, the drive assembly 7 includes a take-up roller 71 rotatably connected in the drive cavity 102. A motor 72 is fixedly installed in the drive cavity 102. The output shaft of the motor 72 is coaxially fixedly connected to the take-up roller 71. A pull rope 73 corresponding to a plurality of moving blocks 62 is wound on the take-up roller 71. The free end of the pull rope 73 extends into the moving groove 6 and is fixedly connected to the corresponding moving block 62. An elastic rope 74 is provided in each moving groove 6. One end of the elastic rope 74 is fixedly connected to the end of the moving groove 6 away from the drive cavity 102, and the other end is fixedly connected to the moving block 62. In the natural state of the elastic rope 74, the moving block 62 is located at the end of the moving groove 6 away from the drive cavity 102.
[0042] Reference Figure 1 and Figure 5 The inner wall of the rainproof shell 1 near the drive cavity 102 is provided with impurity channels 8 corresponding to multiple waterproof baffles 2. The impurity channels 8 are connected to the upper surface of the filter plate 4 on the corresponding waterproof baffle 2. The rainproof shell 1 is provided with a waste area 81 connected to multiple impurity channels 8. The multiple impurity channels 8 are all inclined from top to bottom along the direction close to the waste area 81. Each waste area 81 is hinged with a waste door 82 on its outer surface.
[0043] Motor 72 drives take-up roller 71 to rotate forward, and take-up roller 71 drives pull rope 73 to wind up. At this time, the free end of pull rope 73 pulls moving block 62 towards drive cavity 102, and elastic rope 74 is continuously tensioned. When moving block 62 moves to the end of moving groove 6 near drive cavity 102, motor 72 drives take-up roller 71 to rotate in the opposite direction, and take-up roller 71 loosens pull rope 73. Pull rope 73 is continuously slack, and elastic rope 74, under the action of elastic force, pulls moving block 62 to move continuously away from drive cavity 102. This arrangement is practical. The moving block 62 reciprocates within the moving groove 6, driving the cleaning rod 63 to move on the surface of the filter plate 4. As the cleaning rod 63 moves, it pushes large impurities intercepted on the surface of the filter plate 4 into the impurity channel 8. Under the influence of gravity, the large impurities automatically slide down along the impurity channel 8 to the waste area 81. Workers can periodically open the waste door 82 to clean the collected impurities, thus ensuring that the pores of the filter plate 4 are unobstructed and effectively avoiding the possibility of rainwater infiltration difficulties due to clogging of the pores of the filter plate 4, and ensuring that the drainage path of the rain shelter 3 is unobstructed.
[0044] The implementation principle of a canopy for a gas turbine intake system in this application embodiment is as follows: When the gas turbine is running, the filter plate 4 physically intercepts large debris such as leaves and plastic pieces, preventing large impurities from entering the water collection trough area inside the rain shelter 3, avoiding the accumulation of debris near the drain outlet and causing blockage, thereby ensuring the smooth discharge of rainwater inside the rain shelter 3, and effectively reducing the possibility of rainwater overflow causing intake system failure.
[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
