Description

Technical Field

[0001] This invention relates to the field of power facility technology, and more specifically to a method for installing the exterior facade of a converter station curtain wall. Background Technology

[0002] Converter stations are a crucial component of power transmission projects. They are stations established to convert alternating current (AC) to direct current (DC) or vice versa, meeting the power system's requirements for safety, stability, and power quality. Converter stations primarily consist of converter valves and converter transformers. The converter valves, located within the valve hall, generate significant heat during operation, thus requiring cooling systems, such as sprinkler systems, to ensure safe operation at ideal temperatures. However, when outdoor temperatures are high, such as in summer, sunlight can cause the temperature inside the valve hall to rise, making it difficult to cool the converter valves and affecting the operation of internal valves and other equipment.

[0003] Patent CN112218491A discloses a method for reducing the temperature of a converter station valve hall. This method involves installing photovoltaic (PV) equipment on the roof of the valve hall to convert sunlight into electricity, thus reducing the temperature rise caused by sunlight hitting the roof. However, the rising temperature of the external environment still affects the internal temperature of the valve hall through the walls. Currently, installing thermal insulation curtain walls on the walls of the converter station valve hall is a feasible insulation method; however, while existing thermal insulation curtain walls can reduce radiant heat to some extent, they are still insufficient to reduce heat conduction. Therefore, it is necessary to optimize the existing curtain wall installation method for converter station valve halls to further reduce the heat conducted to the interior of the valve hall through the valve body walls. Summary of the Invention

[0004] The purpose of this invention is to provide a method for installing the exterior facade of a converter station curtain wall. This method involves installing outwardly extending top and side panels on the walls of the converter station valve hall, and then installing the curtain wall on the top and side panels, so that a cooling zone is formed between the curtain wall, top and side panels and the wall. Subsequently, linear guide rail pairs are laid in the cooling zone, and spray equipment is installed on the linear guide rail pairs. As the spray equipment moves along the linear guide rail pairs, it can spray the inner surface of the curtain wall, thereby effectively reducing the heat conducted to the interior of the valve hall through the curtain wall and the wall.

[0005] This invention is achieved through the following technical solution:

[0006] The installation method for the exterior facade of the converter station curtain wall includes the following steps:

[0007] Install top and side panels on the outer wall of the converter station valve hall;

[0008] A curtain wall is installed on the top slab and side slabs, and the curtain wall, together with the top slab, side slabs, and wall, forms a closed cooling zone;

[0009] A linear guide rail pair is installed in the cooling zone, and a spraying device is connected to the linear guide rail pair. The spraying device can move along the linear guide rail pair between the two side plates and is used to spray coolant onto the curtain wall.

[0010] In this technical solution, a curtain wall is installed on at least one wall of the converter valve hall in the converter station. Specifically, a top plate and two side plates are installed on the wall, wherein the top plate and side plates, the top plate and the wall, and the side plates and the wall can be connected by fasteners. In one or more embodiments, the top plate or side plates may also be composed of multiple panels spliced ​​together.

[0011] In this technical solution, aluminum profiles, stainless steel tie rods, and other connectors or fasteners are provided on the top and side panels to install the curtain wall on the top or side panels. In some embodiments, for valve halls with smaller areas, a single curtain wall can be fixed to the top or side panels. In other embodiments, for valve halls with larger areas, a modular curtain wall can be used. After the curtain wall is installed, the inner side of the curtain wall, the inner side of the top panel, and the inner sides of the two side panels, together with the wall, form a closed cooling zone. In one or more embodiments, through holes can also be opened on the two side panels to increase gas flow within the cooling zone.

[0012] In this technical solution, at least one linear guide pair is installed at different heights within the cooling zone. For example, a linear guide pair can be installed only on the lower surface of the top plate, or one or more mounting plates can be provided between the two side plates, and the linear guide pair can be installed on the mounting plates. The linear guide pair can be a conventional linear guide pair. In one or more embodiments, the linear guide pair includes a guide rail mounted on the top plate or mounting plate, a slider capable of moving along the guide rail, and a first motor for driving the slider's movement. The first motor can be installed either inside or outside the cooling zone. A spraying device can be installed on the slider of the linear guide pair, allowing the spraying device to move linearly along the guide rail in front of the two side plates. During movement, the spraying device sprays its internal coolant onto the curtain wall to reduce the temperature transferred to the inner side of the curtain wall, thereby reducing the heat conducted from the curtain wall to the wall and the interior of the valve hall. In some embodiments, the spraying device can be directly installed on the slider or suspended from the slider by a traction rope.

[0013] In this technical solution, a cooling zone is formed by installing a top plate, side plates, and curtain wall on the side wall of the valve hall. The inner wall of the curtain wall is sprayed with a mobile spraying device installed in the cooling zone, which effectively reduces the heat conducted from the curtain wall to the wall and the interior of the valve hall. At the same time, the mobile spraying device can continuously cool various parts of the curtain wall, which not only reduces the amount of cooling water used, but also avoids the internal stress caused by excessive local temperature of the curtain wall, and can effectively extend the service life of the curtain wall.

[0014] Furthermore, the method includes the following step: laying a heat insulation film on the outer surfaces of the top panel, side panels, and curtain wall. By laying a heat insulation film on the outer surfaces of the top panel, side panels, and curtain wall, the radiant heat generated by sunlight on the top panel, side panels, and curtain wall can be effectively reduced, resulting in a lower temperature in the cooling zone, further improving the cooling effect of the spray equipment, and reducing the heat conducted from the curtain wall to the interior of the valve hall.

[0015] Furthermore, the method also includes the following steps: setting up a partition in the cooling zone, the partition dividing the cooling zone into a sound-absorbing zone near the wall and a spray zone away from the wall, the spray equipment operating in the spray zone; and installing a sound-absorbing panel located in the sound-absorbing zone on the partition.

[0016] In this technical solution, a partition installed within the cooling zone further divides it into a sound-absorbing zone and a spray zone. The sound-absorbing zone is the space between the partition and the wall, while the spray zone is the space between the partition and the curtain wall. The sound-absorbing panels installed in the sound-absorbing zone can be made of existing porous sound-absorbing materials to absorb noise transmitted from the valve hall through the wall. The spray equipment operates within the spray zone to prevent the sprayed water from contacting the sound-absorbing panels and reducing their sound absorption effect.

[0017] Furthermore, the spraying equipment is used to spray coolant onto the curtain wall and partitions. The noise within the converter station valve hall is primarily low-frequency noise. To achieve better absorption of low-frequency noise, it is generally desirable to use relatively thick sound-absorbing panels. However, thicker sound-absorbing panels also offer better thermal insulation. In this technical solution, the spraying equipment is configured for bidirectional spraying, which can reduce the temperature of both the inner surface of the curtain wall and the partitions, thereby reducing the heat conducted to the sound-absorbing panels through the partitions and lowering the temperature of the sound-absorbing panels. This allows for the use of thicker sound-absorbing panels in the design to improve sound absorption.

[0018] Furthermore, the method includes the following steps: A liquid guide plate and a drain trough are installed at the bottom of the cooling zone. After the coolant falls onto the liquid guide plate, it is discharged from the cooling zone through the drain trough. The coolant sprayed onto the curtain wall by the spraying equipment flows onto the liquid guide plate and then along the liquid guide plate to the drain trough, ultimately being discharged from the cooling zone through the drain trough.

[0019] As a preferred structure of the spraying device in this invention, the spraying device includes a housing, within which a first baffle and a second baffle are provided. The first baffle divides the internal space of the housing into a liquid storage area and a spraying area, and has a first through hole connecting the liquid storage area and the spraying area. The second baffle divides the spraying area into a pressurization area and a speed-increasing area, and has a second through hole connecting the pressurization area and the speed-increasing area. The speed-increasing area is connected to the outside of the housing via a spray hole. The housing is also provided with an extrusion member and a drive gear. The extrusion member has a groove, within which a rack matching the drive gear is disposed. The bottom end of the extrusion member movably penetrates the top of the housing and extends into the pressurization area. The extrusion member is used to pressurize the cooling pressure in the pressurization area into the speed-increasing area and spray it out through the spray hole.

[0020] In this technical solution, the spraying equipment has a liquid storage zone, a pressurization zone, and an acceleration zone inside its casing. The liquid storage zone and the pressurization zone are separated by a first baffle, and the pressurization zone and the acceleration zone are separated by a second baffle. The casing can contain one or more pressurization and acceleration zones. The first through-hole between the reservoir and the pressurization zone can be configured according to actual needs. For example, in the case of a switch mechanism, the first through-hole can be located in the lower half of the first baffle to allow liquid from the bottom of the reservoir to enter the pressurization zone without the problem of coolant being forced back into the reservoir during pressurization. In the case of no switch mechanism, the first through-hole can be located in the upper half of the first baffle so that the extruder can block the first through-hole when passing through it, and also prevent coolant from being forced back into the reservoir. However, since the first through-hole is located at a high position, the liquid in the reservoir cannot completely enter the pressurization zone. This problem can be solved by setting an inlet hole on the housing to continuously replenish the coolant discharged from the drain tank into the reservoir via a pump and bellows.

[0021] In this technical solution, an extrusion component is movably mounted in the extrusion zone, and a rack on the extrusion component meshes with a drive gear. The drive gear rotates under the drive of a motor, simultaneously driving the extrusion component to move vertically. When the extrusion component moves downwards to the pressurization zone, the volume of the pressurization zone gradually decreases, and the coolant in the pressurization zone is forced into the acceleration zone. When the extrusion component moves upwards until the first through-hole connects, the coolant in the storage zone can refill the pressurization zone and acceleration zone through the first and second through-holes, preparing for the next pressurized spraying.

[0022] In this technical solution, the extrusion component is driven by a drive gear to move vertically within the extrusion zone to generate pressure for spraying coolant. This not only makes the adjustment of the spray pressure more flexible, but also eliminates the need to maintain a high-pressure state inside the casing, making the operation of the spraying equipment safer and more reliable.

[0023] Furthermore, the first baffle is also provided with a third through hole located above the first through hole. A driving member is movably disposed in the third through hole. The driving member is connected to a blocking member via a connecting rod. A first spring is disposed between the connecting member and the first baffle. The squeezing member can push the driving member to move into the third through hole, causing the first baffle to switch from a connected state to a closed state. In the connected state, the blocking member is located in the pressurized area, and the first spring is in a natural state, and the liquid storage area is connected to the pressurized area. In the closed state, the blocking member is located in the first through hole, and the first spring is in a stretched state, and the liquid storage area is not connected to the pressurized area.

[0024] In this technical solution, a switching mechanism is provided on the first baffle to allow the first baffle to have both a connected state and a closed state. Specifically, a third through hole is also provided on the first baffle. Preferably, the first through hole can be located in the lower half of the first baffle, such as the bottom, to allow coolant with a lower liquid level to still enter the pressurized zone in the connected state. The third through hole can be located in the upper half of the first baffle to allow the first baffle to enter the closed state as early as possible.

[0025] In this technical solution, the switching mechanism includes a connecting rod. The upper end of the connecting rod is connected to a driving component, and the lower end of the connecting rod is connected to a blocking component. A first spring is also provided between the connecting rod and the first baffle. When the pressing component is above the driving component, the first baffle is in a connected state. At this time, the end of the driving component is located within the pressurization zone, the spring is in a naturally stretched state, and the blocking component is also located within the pressurization zone. Because the diameter of the short column connecting the blocking component and the connecting rod is smaller than that of the first through hole, it cannot block the first through hole, allowing the coolant in the storage zone to enter the pressurization zone through the first through hole. When the extruder passes the drive member, the extruder pushes the drive member to move towards the liquid storage area against the force of the first spring. The drive member drives the plugging member to move into the first through hole through the connecting rod to block the first through hole. At this time, the first spring is in a stretched state, the first baffle enters the closed state, and during the pressing process of the extruder, the outer wall of the extruder always acts on the drive member to prevent it from resetting. When the extruder moves above the drive member again, the drive member resets under the action of the first spring, and at the same time drives the plugging member to move out of the first through hole, and the first baffle enters the connected state again.

[0026] In this technical solution, the switching mechanism allows the first through hole to be positioned in the lower half of the first baffle, so that liquid with a lower liquid level in the storage area can enter the pressurization area, thereby improving the continuous spraying capacity of the spraying equipment.

[0027] Furthermore, a second motor is also installed on the housing. The output end of the second motor is connected to the shaft of the traction rope drum. A traction rope is wound on the traction rope drum and connected to the slider of the linear guide pair. One end of the traction rope is connected to the slider, and the other end is connected to the traction rope drum. The second motor drives the traction rope drum to rotate, thereby releasing or rewinding the traction rope, thus adjusting the vertical height of the sprinkler equipment to cool down areas with high local temperatures, further improving the flexibility of the sprinkler equipment's movement.

[0028] Furthermore, the drive gear is mounted on the rotating shaft of the traction rope drum, and the drive gear rotates synchronously with the traction rope drum. In this technical solution, the drive gear is also mounted on the rotating shaft of the traction rope drum, so that while the second motor drives the traction rope drum to rotate and retract the traction rope and adjust the height of the spraying equipment, it can also drive the drive gear to rotate, thereby driving the extruder to move within the extrusion zone to spray coolant. The advantage of this arrangement is that it reduces the number of motors installed on the housing, thereby reducing the heat generated by the motors and improving the reliability of the spraying equipment. At the same time, it can correlate the spraying of coolant with the height of the spraying equipment, allowing for greater flexibility in planning the cooling area. For example, when the spraying equipment moves to its lowest point of travel, the extruder also moves to its lowest point of travel, thus allowing the spraying volume and spraying pressure of the spraying equipment to gradually decrease from top to bottom without the need for additional electrical control equipment. This makes it easier for the coolant droplets on the upper part of the curtain wall to collect and flow downwards along the curtain wall, and during the flow, they combine with the newly sprayed coolant to cool the curtain wall.

[0029] Furthermore, a mounting cylinder is provided on the housing, and a telescopic rod is movably mounted on the mounting cylinder. One end of the telescopic rod is connected to a second spring located inside the mounting cylinder, and the other end of the telescopic rod is connected to a roller located outside the mounting cylinder. In this technical solution, for a spraying device suspended in the cooling zone by a traction rope, the roller can better stabilize the spraying device and avoid significant shaking, thus preventing any impact on the spraying effect.

[0030] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0031] 1. This invention creates a cooling zone by installing a top plate, side plates, and curtain wall on the side wall of the valve hall, and uses a mobile spraying device installed in the cooling zone to spray the inner wall of the curtain wall, effectively reducing the heat conducted from the curtain wall to the wall and the interior of the valve hall; at the same time, the mobile spraying device can continuously cool various parts of the curtain wall, which not only reduces the amount of cooling water used, but also avoids the internal stress caused by excessive local temperature of the curtain wall, and can effectively extend the service life of the curtain wall;

[0032] 2. The present invention sets the spraying equipment to bidirectional spraying, which can reduce the temperature of the inner surface of the curtain wall and the temperature of the partition, thereby reducing the heat conducted to the sound-absorbing panel through the partition and reducing the temperature of the sound-absorbing panel. This allows for the use of thicker sound-absorbing panels to improve the sound absorption effect when designing the sound-absorbing panel.

[0033] 3. The present invention uses a drive gear to drive the extrusion piece to move vertically within the extrusion zone to generate pressure for spraying coolant. This not only makes the adjustment of the spray pressure more flexible, but also eliminates the need to maintain a high-pressure state inside the housing, making the operation of the spraying equipment safer and more reliable.

[0034] 4. The switching mechanism provided in this invention allows the first through hole to be positioned in the lower half of the first baffle, so that liquid with a lower liquid level in the storage area can enter the pressurization area, thereby improving the continuous spraying capacity of the spraying equipment.

[0035] 5. By mounting the drive gear on the rotating shaft of the traction rope drum, the present invention can reduce the number of motors installed on the housing, thereby reducing the heat generated by the motors and improving the reliability of the spraying equipment. At the same time, it can correlate the spraying of coolant with the height of the spraying equipment, so as to be more flexible in planning the cooling area. Attached Figure Description

[0048] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0049] In the description of this invention, it should be understood that the terms "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "high", "low", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this invention.

[0050] Example 1:

[0051] like Figures 1 to 4 The installation method for the exterior facade of the converter station curtain wall shown includes the following steps:

[0052] Install a top plate 31 and a side plate 39 on the outer wall of the valve hall of the converter station;

[0053] A curtain wall 32 is installed on the top plate 31 and the side plate 39. The curtain wall 32, together with the top plate 31, the side plate 39, and the wall 1, forms a closed cooling zone 33.

[0054] A linear guide rail pair 34 is installed in the cooling zone 33. A spraying device 4 is connected to the linear guide rail pair 34. The spraying device 4 can move along the linear guide rail pair 34 between the two side plates 39. The spraying device 4 is used to spray coolant onto the curtain wall 32.

[0055] The linear guide pair can be a linear guide pair in the prior art. In one or more embodiments, the linear guide pair includes a guide rail mounted on a top plate or mounting plate, a slider that can move along the guide rail, and a first motor for driving the slider to move. The first motor can be installed either inside or outside the cooling zone.

[0056] In some embodiments, the method further includes the following step: laying a heat insulation film on the outer surfaces of the top panel 31, side panels 39, and curtain wall 32. The heat insulation film can effectively reduce the radiant heat generated by sunlight shining on the top panel, side panels, and curtain wall, resulting in a lower temperature in the cooling zone, further improving the cooling effect of the spray equipment, and reducing the heat conducted from the curtain wall to the interior of the valve hall.

[0057] Example 2:

[0058] Based on Example 1, such as Figure 3 As shown, the process also includes the following steps: A partition 36 is installed within the cooling zone 33, dividing the cooling zone 33 into a sound-absorbing zone near the wall 1 and a spray zone away from the wall 1; the spray device 4 operates within the spray zone; sound-absorbing panels 35 located in the sound-absorbing zone are installed on the partition 36; the spray device 4 is used to spray coolant onto the curtain wall 32 and the partition 36. By configuring the spray device for bidirectional spraying, the temperature of both the inner surface of the curtain wall and the partition can be reduced, thereby reducing the heat conducted to the sound-absorbing panels through the partition and lowering the temperature of the sound-absorbing panels. This allows for the use of thicker sound-absorbing panels to improve sound absorption.

[0059] In some preferred embodiments, the method further includes the following steps: a liquid guide plate 37 and a drain trough 38 are provided at the bottom of the cooling zone 33, and the coolant falls onto the liquid guide plate 37 and is then discharged from the cooling zone 33 through the drain trough 38. In one or more embodiments, the drain trough may be provided on a partition, and the inclined liquid guide plate guides the coolant on it to the drain trough.

[0060] Example 3:

[0061] Based on the above embodiments, such as Figure 5 and Figure 6As shown, the spraying device 4 includes a housing 41. A first baffle 42 and a second baffle 44 are provided inside the housing 41. The first baffle 42 divides the internal space of the housing 41 into a liquid storage area 425 and a spraying area. A first through hole 43 is provided on the first baffle 42 to connect the liquid storage area 425 and the spraying area. The second baffle 44 divides the spraying area into a pressurizing area 426 and a speed-increasing area 427. A second through hole 45 is provided on the second baffle 44 to connect the pressurizing area 426 and the speed-increasing area 427. The speed-increasing area 427 is connected to the outside of the housing 41 via a spray hole 46. The housing 41 also includes an extruder 48 and a drive gear. The extruder 48 has a groove 49, and a rack 410 matching the drive gear is provided in the groove 49. The bottom end of the extruder 48 movably penetrates the top of the housing 41 and extends into the pressurizing area 426. The extruder 48 is used for… The cooling fluid in the pressurization zone 426 is pumped into the acceleration zone 427 and ejected through the nozzle 46. The first baffle 42 is also provided with a third through hole 413 located above the first through hole 43. A driving member 414 is movably disposed within the third through hole 413. The driving member 414 is connected to a blocking member 417 via a connecting rod 416. A first spring 415 is disposed between the connecting member 416 and the first baffle 42. The extrusion member 48 can push the driving member 414 to move into the third through hole 413, causing the first baffle 42 to switch from a connected state to a closed state. In the connected state, the blocking member 417 is located within the pressurization zone 426, and the first spring 415 is in a relaxed state, with the liquid storage zone 425 connected to the pressurization zone 426. In the closed state, the blocking member 417 is located within the first through hole 43, and the first spring 415 is in a stretched state, with the liquid storage zone 425 not connected to the pressurization zone 426.

[0062] In one or more embodiments, the housing is further provided with a liquid inlet hole, which can be connected to a circulation pump through a bellows so that the coolant discharged from the cooling zone through the drain tank can be recycled back into the housing after cooling.

[0063] In some preferred embodiments, the acceleration zone has a smaller cross-sectional area than the pressurization zone. For example, the cross-sectional area of ​​the pressurization zone is 5 to 10 times that of the acceleration zone, thereby causing the coolant to move faster in the acceleration zone and eventually be sprayed out through the nozzles onto the surface of the curtain wall and partition.

[0064] In some preferred embodiments, the nozzles are located near the top of the housing, thereby increasing the spray velocity of the coolant and improving the spraying effect.

[0065] When the extruder is above the drive member, the first baffle is in a connected state. At this time, the end of the drive member is in the pressurization zone, the spring is in a naturally stretched state, and the plug is also in the pressurization zone. The short column connecting the plug and the connecting rod has a smaller diameter than the first through hole, so it cannot block the first through hole, and the coolant in the reservoir can enter the pressurization zone through the first through hole. When the extruder passes the drive member, the extruder pushes the drive member to move towards the reservoir area against the force of the first spring. The drive member drives the plug to move into the first through hole through the connecting rod to block the first through hole. At this time, the first spring is in a stretched state, the first baffle enters a closed state, and during the downward pressing of the extruder, the outer wall of the extruder always acts on the drive member to prevent it from resetting. When the extruder moves above the drive member again, the drive member resets under the action of the first spring, and at the same time drives the plug to move out of the first through hole, and the first baffle enters a connected state again.

[0066] In some embodiments, a second motor 424 is also provided on the housing 41. The output end of the second motor 424 is connected to the shaft of the traction rope drum 422. A traction rope 411 is wound on the traction rope drum 422. The traction rope 411 is connected to the slider 343 of the linear guide pair 34.

[0067] In some embodiments, the drive gear is mounted on the rotating shaft of the traction rope drum 422, and the drive gear rotates synchronously with the traction rope drum 422. In this embodiment, the number of motors installed on the housing can be reduced, thereby reducing the heat generated by the motors and improving the reliability of the spraying equipment. At the same time, the spraying of coolant can be correlated with the height of the spraying equipment, allowing for greater flexibility in planning the cooling area.

[0068] In some preferred embodiments, such as Figure 8 and Figure 9 As shown, a mounting cylinder 419 is provided on the housing 41, and a telescopic rod 420 is movably mounted on the mounting cylinder 419. One end of the telescopic rod 420 is connected to a second spring 423 located inside the mounting cylinder 419, and the other end of the telescopic rod 420 is connected to a roller 421 located outside the mounting cylinder 419. In some embodiments, four rollers are provided on the housing of the spray equipment. Two rollers located on the partition side can roll on the surface of the partition, and two rollers located on the curtain wall side can roll on the surface of the curtain wall to better stabilize the spray equipment. In one or more embodiments, the rollers are casters.

[0069] Example 4:

[0070] Based on Example 3, the structure of the bidirectional spraying equipment is basically the same as that of the unidirectional spraying equipment, such as... Figure 7As shown, it includes a first drive gear 47 and a second drive gear 418 to drive corresponding extruders 48 respectively. Depending on the requirements, during the movement of the spraying equipment, the extruder driven by the first drive gear 47 can cause the corresponding first baffle to enter the connected state, while the extruder driven by the second drive gear 418 can cause the corresponding first baffle to enter the closed state; of course, both extruders can also drive the first baffle to enter the connected or closed state simultaneously.
