Description

Technical Field

[0001] This invention belongs to the technical field of integrated energy storage, converter and booster units, specifically relating to a rainproof, windproof and sand-proof ventilation structure that is easy to maintain. Background Technology

[0002] With the development and utilization of new energy sources, integrated energy storage converters and booster units are playing an increasingly important role in the new energy field. The wind and sand protection and ventilation structure design of these integrated energy storage converters and booster units is crucial to their ventilation and heat dissipation, as well as their stable operation, and can even affect the normal operation of the entire energy storage power station.

[0003] In the application of integrated energy storage converter-boost units, the existing ventilation structure mostly adopts a conventional louver design with dustproof cotton. Although it can meet the basic protection requirements, it has obvious defects: On the one hand, the cross-sectional structure of conventional louvers is not strong enough to resist large sandstorms and cannot effectively prevent sand from entering the equipment; on the other hand, the dustproof cotton is not ideal in preventing wind and dust, which can easily lead to sand accumulation at the air inlet of the integrated unit. At the same time, the maintenance operation of the existing structure is complicated. Replacing the filter components requires disassembling many parts, which is time-consuming and affects the operation and maintenance efficiency of the equipment. This may adversely affect the ventilation, heat dissipation and stable operation of the integrated energy storage converter-boost unit, and even threaten the normal operation of the energy storage power station. Summary of the Invention

[0004] The purpose of this invention is to provide a rainproof, windproof, and sand-proof ventilation structure that is easy to maintain, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A rainproof, windproof, and sandproof ventilation structure that is easy to maintain includes a support frame mechanism, a louver mechanism, and a dustproof mechanism; The support frame mechanism includes an upper support plate, a lower support plate, a left support plate, and a right support plate welded together to form a frame. The left support plate and the right support plate are provided with guide rail grooves formed by longitudinal bending on their inner sides, and welding nuts and screws are welded to the guide rail grooves. The louver mechanism is fixed within the support frame mechanism and consists of a combination structure of multiple blades with fixed spacing. The dustproof mechanism is installed in the guide rail groove of the support frame mechanism by being pulled out, and includes wire mesh, bird netting and a primary filter sandwiched between the two.

[0006] Furthermore, the upper support plate, lower support plate, left support plate, and right support plate of the support frame mechanism are welded with studs for fixing the structure to the equipment shell, and rubber pads are provided at the installation contact points.

[0007] Furthermore, the bottom of the left and right support plates of the support frame mechanism is provided with a lateral bend, which serves as a limiting structure for the dustproof mechanism.

[0008] Furthermore, the blade assembly structure of the louver mechanism includes a first S-shaped blade and a second L-shaped blade, which are fixed together by a hinge; The second L-shaped blade is fixed to the middle bend of the first S-shaped blade by a hinge. The hinge is welded to the second L-shaped blade and connected to the first S-shaped blade by rivets. The first S-shaped blade is a fixed structure, and the second L-shaped blade can rotate through the hinge.

[0009] Furthermore, the wire mesh of the dustproof mechanism is made by hollowing out a U-shaped bending piece and then welding it with wire mesh, and the bird-proof net is made by hollowing out a U-shaped bending piece and then welding it with diamond-shaped bird-proof net.

[0010] Furthermore, the dustproof mechanism controls the compression of the primary filter by adjusting the bending amount of the front wire mesh and the rear bird-proof mesh.

[0011] Furthermore, after the dustproof mechanism is installed, the gap between the dustproof mechanism and the louver mechanism is tightened by tightening the screws at the guide rail groove of the support frame mechanism.

[0012] Furthermore, it also includes multiple smoke sensors installed inside the support frame mechanism (100) for real-time monitoring of smoke concentration inside the structure and generating concentration data; A control unit, electrically connected to all of the smoke sensors, is used to receive the concentration data; The control unit is configured to perform the following steps: Receive concentration data from each smoke sensor; Based on the received concentration data, calculate the effective monitoring concentration value of each smoke sensor; Based on the calculated effective monitoring concentration value and the corresponding smoke sensor's installation position information within the support frame mechanism, the concentration boundary region of the effective monitoring concentration value in spatial distribution is determined. Based on the determined concentration boundary region, a corresponding smoke warning signal is generated.

[0013] Furthermore, determining the concentration boundary region of the effective monitored concentration value in spatial distribution includes: Based on the calculated effective monitoring concentration values, effective monitoring points with concentration values ​​exceeding the preset threshold are selected. Obtain the two-dimensional plane coordinates of the smoke sensor corresponding to each effective monitoring point within the support frame mechanism (100) to construct a set of monitoring point coordinates; From the set of monitoring point coordinates, select the outermost monitoring point as the boundary point; Connect the boundary points sequentially to form a convex polygonal region that completely contains all valid monitoring points; The convex polygonal region is identified and defined as the concentration boundary region of the smoke concentration.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting up a combined structure of a support frame mechanism, a louver mechanism, and a dustproof mechanism, the invention achieves a combination of rainproof and windproof functions with convenient maintenance. The support frame mechanism provides a stable installation foundation for the whole, and its guide rail groove design allows the dustproof mechanism to be installed by insertion and removal, greatly simplifying maintenance operations. The L-shaped and S-shaped combined blade structure of the louver mechanism can effectively block and guide wind, sand, and rainwater from entering the equipment. The dustproof mechanism further improves the dustproof effect through the cooperation of multiple filter components, and the pre-filter can be replaced as needed, ensuring the long-term effective operation of the ventilation structure.

Detailed Implementation

[0017] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "one embodiment" or "example" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the invention. The appearance of an embodiment in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0020] Example Reference Figure 1-6 This embodiment of the present invention provides a rainproof, windproof, and sandproof ventilation structure that is easy to maintain, including a support frame mechanism 100, a louver mechanism 200, and a dustproof mechanism 300. The support frame mechanism 100 includes an upper support plate 110, a lower support plate 120, a left support plate 130 and a right support plate 140 welded together to form a frame. The left support plate 130 and the right support plate 140 are provided with guide rail grooves formed by longitudinal bending on their inner sides, and welding nuts and screws are welded to the guide rail grooves. The louver mechanism 200 is fixed within the support frame mechanism 100 and is composed of multiple blades with fixed spacing. The dustproof mechanism 300 is installed in the guide rail groove of the support frame mechanism 100 by a pull-out method, including wire mesh 310, bird netting 320 and a primary filter 330 sandwiched between the two.

[0021] The system combines a support frame mechanism 100, a louver mechanism 200, and a dustproof mechanism 300 to achieve both rain and sand protection and convenient maintenance. The support frame mechanism 100 provides a stable installation foundation for the entire system, and its guide rail design allows for the removable installation of the dustproof mechanism 300, greatly simplifying maintenance operations. The blade structure of the louver mechanism 200 effectively blocks and guides wind, sand, and rainwater, preventing them from entering the equipment. The dustproof mechanism 300 further enhances the dustproof effect through the cooperation of multiple filter components, and the pre-filter can be replaced as needed, ensuring the long-term effective operation of the ventilation structure.

[0022] Specifically, welding studs are welded onto the upper support plate 110, lower support plate 120, left support plate 130, and right support plate 140 of the support frame mechanism 100 to fix the structure to the equipment shell, and rubber pads are provided at the installation contact points.

[0023] By installing welding studs on each support plate of the support frame mechanism 100, the ventilation structure and the equipment shell are reliably fixed, ensuring the structure remains stable during equipment operation. The rubber pad design at the installation contact point can effectively seal the joint between the structure and the equipment shell, preventing rainwater from seeping into the equipment from the joint, thereby preventing equipment failure due to water ingress and improving the safety and stability of equipment operation.

[0024] Furthermore, the bottom of the left support plate 130 and the right support plate 140 of the support frame mechanism 100 are provided with lateral bends, which serve as the limiting structure of the dustproof mechanism 300.

[0025] Among them, by setting lateral bends at the bottom of the left and right support plates of the support frame mechanism 100, the dustproof mechanism 300 is provided with precise positioning, ensuring that the dustproof mechanism 300 can be quickly positioned during the insertion and removal installation process, avoiding dust leakage caused by installation misalignment; at the same time, the positioning structure also improves the stability of the dustproof mechanism 300 after installation, preventing it from loosening or shifting during equipment operation, and ensuring the continuous effectiveness of the filtration function.

[0026] Preferably, the blade assembly structure of the louver mechanism 200 includes a first S-shaped blade 210 and a second L-shaped blade 220, which are fixed by a hinge. The second L-shaped blade is fixed to the middle bend of the first S-shaped blade via a hinge. The hinge is welded to the second L-shaped blade 220 and connected to the first S-shaped blade 210 via rivets. The first S-shaped blade 210 is a fixed structure, while the second L-shaped blade 220 can rotate via the hinge. The rotatable second L-shaped blade 220 has maximum upper and lower limits to prevent the louvers from completely blocking the ventilation window and obstructing airflow. The louvers are linked by a connecting rod, and the rotation angle of the louvers can be adjusted according to the rainfall level of the area to achieve rain protection.

[0027] The design incorporates different angles and openings to achieve efficient separation of wind and sand and rainwater: the first S-shaped blades can be guided by the structure to allow debris falling onto them to slide off to the outside by gravity; the second L-shaped blades can further block impurities in the airflow, reducing the amount of wind and sand and rainwater entering the equipment; the combination of the two not only extends the movement path of impurities but also improves the purification effect by utilizing the principle of inertial separation, while the rivet fixing method ensures the robustness of the blade structure.

[0028] Furthermore, the wire mesh 310 of the dustproof mechanism 300 is made by hollowing out a U-shaped bent piece and welding it with wire mesh, and the bird net 320 is made by hollowing out a U-shaped bent piece and welding it with diamond-shaped bird net.

[0029] The U-shaped bending structure provides stable support for the pre-filter, preventing deformation due to airflow impact. It also blocks large external particles and birds, reducing the risk of large debris entering the equipment. At the same time, the two mesh designs do not excessively obstruct ventilation, ensuring the equipment's heat dissipation requirements.

[0030] Specifically, the dustproof mechanism 300 controls the compression of the primary filter 330 by adjusting the bending amount of the front wire mesh 310 and the rear bird net 320.

[0031] The compression of the pre-filter 330 is controlled by adjusting the bending amount of the wire mesh 310 and the bird net 320, so that the dustproof mechanism 300 can be adapted to pre-filters of different specifications, thus improving the versatility of the structure. At the same time, the reasonable compression amount can ensure that the pre-filter and the mesh are tightly fitted, preventing impurities from entering through the gap between the filter and the mesh, and ensuring the stability of the filtration effect.

[0032] Furthermore, after the dustproof mechanism 300 is installed, the gap between the dustproof mechanism 300 and the louver mechanism 200 is tightened by tightening the screws at the guide rail groove of the support frame mechanism 100.

[0033] By tightening the gap between the dustproof mechanism 300 and the louver mechanism 200 with screws, wind and sand and dust are effectively prevented from seeping into the equipment through the gap, further improving the sealing performance of the ventilation structure. At the same time, the screw tightening method is simple to operate, which not only ensures the sealing effect, but also does not increase the complexity of maintenance operations, thus taking into account both sealing reliability and maintenance convenience.

[0034] A rainproof, windproof, and sand-proof ventilation structure that is easy to maintain also includes multiple smoke sensors installed on the inner side of the supporting frame mechanism (100) for real-time monitoring of the smoke concentration inside the structure and generating concentration data; a control unit electrically connected to all the smoke sensors for receiving the concentration data; the control unit is configured to perform the following steps: Step 1: Receive concentration data from each smoke sensor. Specifically, this includes: the control unit first completing its own startup self-test to confirm that the internal data receiving module, power module, and communication interface are all in normal working order; simultaneously, it sends an initialization command to all smoke sensors installed inside the support frame, triggering the sensors to perform a power-on self-test to check the sensor's detection element and signal conversion module for proper functioning, ensuring the sensor has data acquisition capability; after each smoke sensor passes its self-test, it actively sends a ready signal back to the control unit. Upon receiving the ready signal, the control unit establishes a stable wired or wireless communication link with each sensor (determined according to the communication method in the structural design), and assigns a unique identification code to each sensor for subsequent differentiation of monitoring data from different sensors; the control unit sends data acquisition commands to all smoke sensors according to a preset acquisition cycle (e.g., once every 2 seconds), or the sensors acquire data according to their own preset acquisition frequency. The system actively collects smoke concentration data. The collection cycle can be preset according to the risk level of the ventilation structure's environment and stored in the control unit. Each smoke sensor transmits the raw smoke concentration data, along with its unique identification code, to the control unit. The control unit receives the data transmitted by each sensor in real time through the data receiving module, and records the reception time of each data point, forming a preliminary data set containing sensor identification, reception time, and raw concentration data. The control unit performs format verification on each received data set, checking whether the data meets the preset transmission format requirements, and discarding data with format errors or missing key information (such as no sensor identification or no concentration value). At the same time, it determines whether the data is within the normal measurement range of the sensor (e.g., the sensor measurement range is 0-1000ppm, and data outside this range is considered invalid data). Invalid data is marked and temporarily stored for subsequent troubleshooting.

[0035] Step 2: Based on the received concentration data, calculate the effective monitoring concentration value of each smoke sensor. Specifically, the control unit further filters out abnormal fluctuation data for each set of data received and preliminarily verified in Step 1. Specifically, it retrieves historical valid data from the sensor within the most recent three consecutive (preset) acquisition periods, calculates the fluctuation range of the historical data (e.g., the difference between the maximum and minimum values), and if the difference between the current data and the average value of the historical data exceeds a preset fluctuation threshold (e.g., ±50ppm, which can be adjusted according to the sensor's accuracy), it is determined to be abnormal fluctuation data and discarded.

[0036] For current data that has not been rejected, its validity is verified by combining the performance parameters of the smoke sensor itself (such as measurement accuracy and error range). Based on the sensor's factory-calibrated error value (e.g., ±3%), a reasonable error range for the current data is calculated. If the data is within this error range, it is considered valid raw data. If it exceeds the error range, it is further compared with data from adjacent sensors within the same acquisition period. If the data from adjacent sensors are all normal, and only the data from this sensor exceeds the error range, the data is deemed invalid and the sensor is marked as potentially faulty.

[0037] For raw data that has passed validity verification, if the sensor collects only one set of valid raw data in a single acquisition cycle, then the raw data is directly used as the valid monitoring concentration value collected by the sensor in this acquisition cycle; if, in order to improve data accuracy, the sensor collects multiple sets of valid raw data in a single acquisition cycle (such as collecting 3 sets of data consecutively), then the arithmetic mean of these multiple sets of data is calculated, and the average value is used as the valid monitoring concentration value collected by the sensor in this acquisition cycle.

[0038] The calculated effective monitoring concentration values ​​of each sensor are associated with and stored with the corresponding sensor identification, acquisition time, and installation location information to form a complete data record of sensor identification, installation location, acquisition time, and effective monitoring concentration value.

[0039] Step 3: Based on the calculated effective monitoring concentration value and the corresponding installation position information of the smoke sensor within the support frame mechanism (100), determine the concentration boundary region of the effective monitoring concentration value in spatial distribution; determining the concentration boundary region of the effective monitoring concentration value in spatial distribution includes: Based on the calculated effective monitoring concentration values, effective monitoring points with concentration values ​​exceeding a preset threshold are selected; the two-dimensional plane coordinates of the smoke sensor corresponding to each effective monitoring point within the support frame mechanism (100) are obtained to construct a set of monitoring point coordinates; from the set of monitoring point coordinates, the outermost monitoring point is selected as the boundary point; the boundary points are connected sequentially to form a convex polygonal region that completely contains all effective monitoring points; the convex polygonal region is identified and defined as the concentration boundary region of the smoke concentration, specifically including: the control unit retrieves the preset smoke concentration safety threshold from the complete data record generated in step 2 (this threshold is preset and stored according to the safety requirements of the equipment protected by the ventilation structure, and can be divided into multiple levels such as warning threshold and danger threshold; here, the preset warning threshold is selected), compares the effective monitoring concentration values ​​of each sensor one by one, selects all monitoring points with effective monitoring concentration values ​​exceeding the preset threshold, forms a set of monitoring points exceeding the threshold, and records the sensor identifier and effective monitoring concentration value corresponding to each monitoring point exceeding the threshold.

[0040] The control unit retrieves the two-dimensional plane coordinates of each corresponding sensor inside the support frame mechanism from the pre-stored sensor information database based on the sensor identifier in the set of over-threshold monitoring points (these coordinates have been calibrated during sensor installation, with the lower left corner of the support frame mechanism as the origin, the horizontal direction as the X-axis, and the vertical direction as the Y-axis, and the coordinate unit is millimeters); and binds the effective monitoring concentration value of the over-threshold monitoring point to its two-dimensional plane coordinates to construct a set of over-threshold monitoring point coordinates containing the two-dimensional plane coordinates and the effective monitoring concentration value.

[0041] First, extreme value analysis is performed on all coordinates in the set of monitoring points exceeding the threshold along the X and Y axes. The four monitoring points corresponding to the minimum X-axis value (leftmost), maximum X-axis value (rightmost), minimum Y-axis value (bottommost), and maximum Y-axis value (topmost) are selected as initial boundary points. Then, all remaining monitoring points in the coordinate set are traversed. For each remaining monitoring point, it is determined whether it is a boundary point by judging whether it is located outside the polygon formed by the selected initial boundary points. Specifically, if the angle formed by the line connecting the monitoring point and any two adjacent initial boundary points is an acute angle, or if the distance from the point to any initial boundary point exceeds a preset range, then the point is determined to be an outer boundary point and added to the boundary point set. This process is repeated until all remaining monitoring points have been judged, and a complete boundary point set is finally formed.

[0042] The boundary points in the boundary point set are sorted clockwise or counterclockwise, with the sorting rule based on the origin and according to the angle between each boundary point and the origin. Following the sorted order, adjacent boundary points are connected by straight lines, and finally, the last boundary point is connected to the first boundary point to form a closed polygon. The integrity of the polygon is verified by checking whether it contains all the super-threshold monitoring points (i.e., the coordinates of all super-threshold monitoring points satisfy the boundary inequality condition of the polygon). If any super-threshold monitoring points are not included, the boundary point selection process is re-checked, and the missing boundary points are added before reconnecting, until the resulting polygon completely contains all super-threshold monitoring points. Finally, this closed convex polygon region is identified and defined as the concentration boundary region of the smoke concentration, and the two-dimensional plane coordinates of all boundary points in this region are recorded.

[0043] Step 4: Based on the determined concentration boundary area, generate a corresponding smoke warning signal. Specifically, the control unit extracts the key feature parameters of the concentration boundary area determined in Step 3, including the area of ​​the area (calculated by the coordinates of the boundary points of the convex polygon), the location of the area within the supporting frame structure (such as near the core area of ​​the equipment, near the ventilation inlet area, etc.), the highest effective monitoring concentration value and the average effective monitoring concentration value of the monitoring points exceeding the threshold within the area.

[0044] The control unit retrieves preset multi-level warning standards. These standards are pre-defined based on the size of the concentration boundary area, the concentration value within the area, and the importance of the area's location. For example: Level 1 Warning (Low Risk): The area of ​​the concentration boundary area is less than 0.1 square meters, the highest concentration value within the area is less than 1.2 times the warning threshold, and the area is far from the core equipment area; Level 2 Warning (Medium Risk): The area of ​​the concentration boundary area is between 0.1 and 0.5 square meters, the highest concentration value within the area is 1.2 to 1.5 times the warning threshold, or the area is close to the core equipment area; Level 3 Warning (High Risk): The area of ​​the concentration boundary area is greater than 0.5 square meters, the highest concentration value within the area exceeds 1.5 times the warning threshold, or the area directly covers the core equipment area. The control unit compares the analyzed concentration boundary area characteristic parameters with the preset multi-level warning standards one by one to determine the warning level corresponding to the current smoke concentration.

[0045] Based on the determined warning level, the control unit generates a corresponding smoke warning signal. Different warning levels correspond to different signal parameters. For example, the first-level warning signal is a low-frequency audible and visual signal (e.g., an audible warning every 3 seconds and a flashing warning indicator every 3 seconds), and simultaneously generates a text warning message containing the warning level, the location of the concentration boundary area, and the highest concentration value; the second-level warning signal is a medium-frequency audible and visual signal (e.g., an audible warning every 1 second and a flashing warning indicator every 1 second), and the text warning message includes statistics on the warning duration; the third-level warning signal is a high-frequency audible and visual signal (a continuous audible warning and a constantly flashing warning indicator), and the text warning message includes emergency response suggestions, while simultaneously generating a linkage control signal (if the system has linkage functionality).

[0046] The control unit transmits the generated audible and visual warning signals to the corresponding warning devices (such as speakers and warning indicator lights) through its own signal output interface, triggering the activation of the warning devices. At the same time, it transmits text warning information and warning signal parameters to the local display terminal (such as the control panel display screen) for real-time display and stores them in the control unit's local storage module, recording data such as warning trigger time, warning level, detailed information on the concentration boundary area, and warning signal output status. If the system is connected to a remote monitoring platform, the control unit also uploads the warning information to the remote monitoring platform through the communication module to achieve remote warning prompts.
