Description

Technical Field

[0001] The present invention relates to the technical field of substation equipment, and in particular to a louver, an adjustment method and a box-type substation. Background Art

[0002] At present, the degree of integration and modularization of box-type substations is getting higher and higher. The application of high integration and modularization has higher and higher requirements for the ventilation of box-type substations, and at the same time, the requirements for the internal cleanliness have also been initially improved. The application environment of box-type substations is diverse. The air inlets and outlets for internal ventilation and heat dissipation are installed with louvers to prevent dust and rain. However, due to the large distance between the blades of the louvers, it is impossible to effectively block particulate impurities and dust. Especially in strong wind weather, a large amount of particulate dust and impurities are often blown into the box through the louvers, which brings great harm to the operation and maintenance of the equipment inside the box.

[0003] The prior art requires regular manual cleaning of impurities and dust particles in the box, or installing a layer of high-precision filter behind the louver. However, due to the high precision and large back pressure of the filter, it seriously affects the ventilation pressure inside the box. And regular cleaning of the box also increases the operation and maintenance costs, and due to the settlement of a large amount of dust particles and impurities, it is extremely harmful to the equipment inside the box.

[0004] Therefore, there is an urgent need for a louver to solve the above technical problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a louver, an adjustment method and a box-type substation, which can not only meet the ventilation pressure requirements of the equipment inside the box, but also effectively reduce the dust and impurities entering the box-type substation.

[0006] To achieve this purpose, the present invention adopts the following technical solutions:

[0008] An installation frame, the installation frame includes at least two oppositely arranged columns;

[0009] Multiple single-piece window leaves, rotatably connected to the upright posts, are arranged in sequence from top to bottom. The top of the single-piece window leaf bends downward to form a first hook, and the bottom of the single-piece window leaf bends upward to form a second hook. The first hook and the second hook are respectively located on both sides of the single-piece window leaf. Among two adjacent single-piece window leaves, the first hook of one single-piece window leaf extends into the area enclosed by the second hook of the other single-piece window leaf, and the first hook and the second hook form a channel for air flow to enter. The central axis of the single-piece window leaf along the length direction is arranged at a first angle with the bottom surface of the upright post, and the main side wall of each single-piece window leaf is arranged at a second angle with the bottom surface of the upright post.

The second rotating pin passes through the jack, the first rotating pin extends into the installation hole of the upright post, and the rotating shaft passes through the threaded hole and is screwed to the adjusting column.

[0014] As a preferred technical solution of the above-mentioned louver, the installation frame further includes a dust collection cover. The dust collection cover encloses an installation cavity with a socket. The adjusting column and the upright post are both arranged in the installation cavity. The single-piece window leaf passes through the socket and is respectively connected to the upright post and the adjusting column. One end of the rotating shaft passing through the adjusting column is rotatably connected to the side wall of the dust collection cover.

[0015] As a preferred technical solution of the above-mentioned louver, the adjusting structure further includes a driving member, and the rotating shaft is connected to the driving member to be driven to rotate by the driving member.

[0016] In a second aspect, a louver adjusting method is provided, which is applied to the louver described in any of the above solutions, and includes the following steps:

[0017] Obtain the current wind speed, current air density, and the minimum particle radius in the current air;

The channel is inclined along the length direction of the single window leaf, which can guide the dust to avoid dust clogging the channel. In this way, dust particles and impurities can be filtered to ensure that the inside of the box is clean. Description of the Drawings

[0033] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only parts related to the present invention rather than all structures are shown in the drawings.

[0034] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components.

Moreover, the first feature being "above", "over" and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely means that the horizontal height of the first feature is lower than that of the second feature.

[0036] In the description of this embodiment, the orientation or positional relationships such as "up", "down", "right", etc. are based on the orientation or positional relationship shown in the drawings. It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0037] The louver of the box-type power station is used for ventilation, heat dissipation, dust prevention and rain protection. However, the current louvers cannot meet both the ventilation pressure requirements and filter dust particles and impurities to ensure the cleanliness inside the box. For this reason, an embodiment of the present invention provides a louver to solve the above technical problems.

[0038] As Figures 1 to 4 shown, the present invention provides a louver, which includes an installation frame 1 and a plurality of single-piece window leaves 2. The plurality of single-piece window leaves 2 are rotatably arranged on the installation frame 1 to rotate relative to the installation frame 1, so as to adjust the distance between adjacent single-piece window leaves 2, and further achieve the purpose of adjusting the air volume passing through the louver. The installation frame 1 includes at least two oppositely arranged columns 11; the plurality of single-piece window leaves 2 are rotatably connected to the columns 11. The plurality of single-piece window leaves 2 are arranged in sequence from top to bottom. The top of the single-piece window leaf 2 is bent downward to form a first hook 21, and the bottom of the single-piece window leaf 2 is bent upward to form a second hook 22. The first hook 21 and the second hook 22 are respectively located on both sides of the single-piece window leaf 2. Among two adjacent single-piece window leaves 2, the first hook 21 of one single-piece window leaf 2 extends into the area enclosed by the second hook 22 of the other single-piece window leaf 2, and the first hook 21 and the second hook 22 form a channel 26 for air to enter. The central axis of the single-piece window leaf 2 along the length direction is arranged at a first angle with the bottom surface of the column 11, and the main side wall 23 of each single-piece window leaf 2 is arranged at a second angle with the bottom surface of the column 11.

[0039] Since in adjacent single-pane window leaves 2, the first hook 21 of one single-pane window leaf 2 extends into the area enclosed by the second hook 22 of another single-pane window leaf 2, and the first hook 21 and the second hook 22 enclose a channel 26 for air to enter, so that air can pass through the louver through the channel 26, and the setting of the channel 26 can meet the ventilation pressure requirements of the equipment in the box compared with the filter screen. The central axis of the single-pane window leaf 2 in the length direction is arranged at a first angle with the bottom surface of the column 11, and the main side wall 23 of each single-pane window leaf 2 is arranged at a second angle with the bottom surface of the column 11. In this way, the single-pane window leaf 2 can be inclined. In this way, whether it is large-particle dust or small-particle dust, it can be blocked by the first hook 21 and the second hook 22 and accumulate in the channel 26. The inclination of the channel 26 along the length direction of the single-pane window leaf can guide the dust to avoid dust blocking the channel 26. In this way, dust particles and impurities can be filtered to ensure that the inside of the box is clean and tidy.

[0040] Further, as shown in combination with Figure 1 and Figure 2 , if the second angle is α and the first angle is β, then where ρ is the air density, r is the minimum particle radius in the air, and u is the wind speed. According to the above relational formula, the design structure of the single-pane window leaf 2 and the installation angle of the single-pane window leaf 2 can be obtained, so that the louver can not only meet the ventilation and heat dissipation requirements in the container, but also effectively filter dust particles and impurities.

[0041] To effectively filter dust particles and impurities and keep the inside of the box clean and tidy, the above first angle and second angle are designed for the single-pane window leaf according to the fluid mechanics turbulent vortex theory, shock wave theory and test data, and at the same time, the installation angle of the single-pane window leaf is analyzed. The installation angle of the single-pane window leaf meets the relational formula of each angle fitted above.

[0042] In some embodiments, in order to realize the angle adjustment of the single-pane window leaf 2, as shown in Figure 5 and Figure 6 , the louver further includes an adjustment structure 3. The adjustment structure 3 is connected to the single-pane window leaf 2 to adjust the angle of the second angle of the single-pane window leaf 2. It should be noted that the adjustment structure 3 adjusts the angles of the second angles of multiple single-pane window leaves 2 at the same time, so that the distance between adjacent single-pane window leaves 2 can be adjusted. In this way, according to the different seasons of the application location, especially when the temperature is relatively low in winter, the inside of the container initially needs to be insulated. At this time, the louver can be closed through the adjustment structure 3, thereby accelerating the increase of the internal temperature of the box-type power station.

[0043] Specifically, the above adjustment structure 3 includes a rotating shaft 31. The rotating shaft 31 is connected to the single-pane window leaf 2 and can drive the single-pane window leaf 2 to rotate, so as to achieve the purpose of adjusting the second angle of the single-pane window leaf 2. The setting of the rotating shaft 31 facilitates the angle adjustment of the single-pane window leaf 2.

[0044] In some embodiments, in order to connect the single-pane window leaf 2 to the rotating shaft 31, first rotating pins 24 are provided in the middle of both sides of the single-pane window leaf 2, and a second rotating pin 25 is provided below each of the two sides of the single-pane window leaf 2, that is, a second rotating pin 25 is provided on each of the two sides of the single-pane window leaf 2, and the second rotating pin 25 is located below the first rotating pin 24. The adjusting structure 3 further includes an adjusting column 32. The adjusting column 32 is provided with a threaded hole 322 and a plurality of jacks 3211 arranged along the length direction of the adjusting column 32. The first rotating pin 24 passes through the jacks 3211, and the second rotating pin 25 extends into the jacks 3211 of the upright column 11. The rotating shaft 31 passes through the threaded hole 322 and is screwed to the adjusting column 32. The adjusting column 32 cooperates with the second rotating pin 25 of the single-pane window leaf 2 to limit the up and down movement of the single-pane window leaf 2, and the single-pane window leaf 2 is connected and rotated with the upright column 11 through the rotating shaft 31. In this way, the upright column 11 and the adjusting column 32 cooperate with each other to enable the single-pane window leaf 2 to rotate relative to the bottom surface of the upright column 11, thereby adjusting the second included angle of the single-pane window leaf 2.

[0045] It should be noted that the length extension direction of the upright column 11, the length extension direction of the adjusting column 32, and the length extension direction of the dust collection cover 12 are the same. The horizontal included angles of the first rotating pin 24, the single-pane window leaf 2, and the mounting hole 111 on the upright column 11 are the same, and the first rotating pin 24 and the second rotating pin 25 are arranged at an included angle, and the second rotating pin 25 is arranged horizontally.

[0046] For example, a relief groove or a connecting ear 321 is provided on one side of the adjusting column 32 facing the second rotating pin 25. The number of the connecting ears 321 is the same as that of the single-pane window leaf 2. The connecting ear 321 has a jack 3211 through which the second rotating pin 25 can pass, and the first rotating pin 24 can pass between adjacent connecting ears 321 to prevent the adjusting column 32 from interfering with the first rotating pin 24.

[0047] Since adjacent single-pane window leaves 2 form a channel 26, the channel 26 can ensure that air flows through it. However, if dust accumulates in the channel 26, the channel 26 will be blocked, affecting the air flow. Therefore, the mounting frame 1 further includes a dust collection cover 12. The dust collection cover 12 encloses an installation cavity with a socket. The adjusting column 32 and the upright column 11 are both arranged in the installation cavity. The single-pane window leaf 2 passes through the socket and is respectively connected to the upright column 11 and the adjusting column 32. The rotating shaft 31 passes through one end of the adjusting column 32 and is rotatably connected to the side wall of the dust collection cover 12. The rotating shaft 31 is a threaded shaft, and the threaded shaft rotates relative to the dust collection cover 12. Under the action of the threaded shaft, the adjusting column 32 can move forward or backward, thereby driving the single-pane window leaf 2 to rotate to adjust the angle of the second included angle, and thus the distance between adjacent single-pane window leaves 2 can be adjusted.

[0048] For example, the single-piece window leaf 2 has an S-shaped grooved structure, and a dust collection cover 12 is installed on the side of the shutter. The inside of the dust collection cover 12 is hollow and provided with a dust collection channel. When the wind blows towards the shutter, the dust particles and impurities contained therein will remain in the grooves. Since the installation angle of the single-piece window leaf 2 is obtained through detailed calculation and analysis, the blocked dust particles and impurities can enter the dust collection channel by the wind force, which is convenient for cleaning and discharging.

[0049] According to the thread pitch on the rotating shaft 31, it is very easy to calculate the rotation angle of the single-piece window leaf 2 around the second rotating pin 25 when the rotating shaft 31 rotates one circle, so as to clearly control the opening and closing angle of the single-piece window leaf 2, that is, the second included angle α.

[0050] Specifically, a buckle 34 is provided at one end of the rotating shaft 31 passing through the adjusting column 32. The rotating shaft 31 can be connected and limited with the dust collection cover 12 through the buckle 34 to prevent the rotating shaft 31 from moving axially along it.

[0051] When the angle of the single-piece window leaf 2 can be manually adjusted, the adjusting structure 3 includes an adjusting handwheel 33. The adjusting handwheel 33 is arranged at the other end of the rotating shaft 31 that does not pass through the adjusting column 32. In this way, maintenance personnel can rotate the adjusting handwheel 33 to adjust the second included angle of the single-piece window leaf 2.

[0052] In order to adjust the second included angle of the single-piece window leaf 2, the adjusting structure 3 further includes a driving member. The rotating shaft 31 is connected to the driving member to be driven by the driving member to rotate. In this way, the single-piece window leaf 2 can be driven to rotate by controlling the driving member. For example, the driving member is a motor, and the motor can be a stepping motor or a servo motor.

[0053] For example, for a certain box-type power station of the company, according to the environmental data of its application site over the years, it is found that the maximum wind force in this area is level 8, and the main component in the local dust is rock particles. By querying relevant standards and manuals, the minimum particle density ρ in the air is 3.3 g / cm 3 , the wind speed u at level 8 is 20.7 m / s, and the minimum particle radius r in the air is 0.25 mm. Substituting the above parameters into the relational formula:

[0054]

[0055] It is obtained that: 0° < α < 66°, 90° > β ≥ 21.26°

[0056] Through the above analysis and calculation, the design structure of the single-piece window leaf 2 can be obtained, that is, its reverse S-shaped structure and the maximum angle of the groove, as well as the minimum installation angle of the single-piece window leaf 2, so as to meet the use requirements of preventing wind and sand and impurities.

[0057] The present invention also provides a shutter adjustment method, which is applied to the shutter provided in the embodiment of the present invention, as Figure 7 shown, and includes the following steps:

[0058] S101. Obtain the current wind speed, current air density, and the minimum particle radius in the current air;

[0059] The current wind speed, current air density, and the minimum particle radius in the current air are obtained within a preset time. For example, the above three parameters are obtained at 12 o'clock noon every day, or the above three parameters can be obtained once every five days, so as to achieve the purpose of the single window leaf 2.

[0060] S102. Adjust the second angle α of the single window leaf based on the current wind speed, current air density, and the minimum particle radius in the current air, where

[0061] Obtain the current season and determine whether the season has changed. If it has changed, then adjust the second angle α of the single window leaf based on the current wind speed, current air density, and the minimum particle radius in the current air, where Specifically, the current season can be obtained through local time, and the local time includes X year X month X day, so that the local season can be quickly determined. The current wind speed can be obtained through an anemometer or through a network method (including relevant content of local air quality). Similarly, the current air density and the minimum particle radius in the current air can also be obtained through a network method.

[0062] Specifically, the blind is installed with a controller. The controller can calculate the second angle α and the first angle β based on the current wind speed, current air density, and the minimum particle radius in the current air, and can control the driving member to work according to the obtained relevant angles to adjust the angle of the single window leaf 2.

[0063] The present invention also provides a box-type power station, which includes a housing and the blind provided by the embodiment of the present invention. The housing has a ventilation opening, and the blind is installed at the ventilation opening to block the entry of dust particles.

[0064] In the adjacent single-pane window leaves 2, the first hook 21 of one of the single-pane window leaves 2 extends into the area enclosed by the second hook 22 of the other single-pane window leaf 2, and a channel 26 for the airflow to enter is formed by the first hook 21 and the second hook 22. In this way, air can pass through the louver through the channel 26, and the setting of the channel 26 can meet the ventilation pressure requirements of the equipment in the box compared with the filter screen. The central axis of the single-pane window leaf 2 in the length direction is arranged at a first angle with the bottom surface of the column 11, and the main side wall 23 of each single-pane window leaf 2 is arranged at a second angle with the bottom surface of the column 11. In this way, the single-pane window leaf 2 can be inclined. In this way, whether it is large-particle dust or small-particle dust, it can be blocked by the first hook 21 and the second hook 22 and accumulate in the channel 26. The inclination of the channel 26 in the length direction of the single-pane window leaf can guide the dust to avoid dust blocking the channel 26. In this way, dust particles and impurities can be filtered to ensure that the inside of the box is clean.

[0065] Due to the inclusion of the above-mentioned louver, the box-type power station of the embodiment of the present invention has all the advantages and beneficial effects of the above embodiment, which will not be elaborated here.

[0066] In addition, the above is only the preferred embodiment of the present invention and the technical principles applied. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described here, and various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the protection scope of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments. Without departing from the concept of the present invention, more other equivalent embodiments can be included, and the scope of the present invention is determined by the scope of the appended claims.
