Description

Technical Field

[0001] This invention relates to the field of air purification technology, and in particular to an air quality purification and monitoring device for basketball training halls. Background Technology

[0002] As enclosed spaces with high foot traffic, basketball training halls are facing increasingly prominent air quality issues. Athletes generate significant amounts of pollutants during training, including sweat odors, carbon dioxide, and dust from floor friction. These pollutants accumulate in the air, easily leading to a decline in indoor air quality and negatively impacting athletes' health and training effectiveness.

[0003] Traditional air purification equipment typically uses a single filtration method, making it difficult to treat different pollutants in layers, and it lacks intelligent monitoring and adjustment functions. Furthermore, existing equipment often fails to account for the different distribution of pollutants at high and low altitudes during air exchange, resulting in low purification efficiency and high maintenance costs. Therefore, there is an urgent need for an air quality purification and monitoring device that can efficiently purify, intelligently monitor, and adapt to the specific needs of a basketball training hall.

[0004] To address the aforementioned issues, we propose an air quality purification and monitoring device for basketball training halls. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art by proposing an air quality purification and monitoring device for basketball training halls.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an air quality purification and monitoring device for a basketball training hall, comprising an equipment box, wherein the equipment box is provided with a horizontal partition and a vertical partition, the horizontal partition dividing the equipment box into an upper cavity and a lower cavity, the vertical partition being located below the horizontal partition and dividing the lower cavity from left to right into a dust collection cavity and an air intake cavity, the horizontal partition having a communication port communicating with the air intake cavity, a conversion box being provided at the lower right corner of the equipment box, a first shaft being rotatably connected to the front and rear center positions of the conversion box, a cross rotating plate being fixedly sleeved on the first shaft, the cross rotating plate and the conversion box... The inner wall of the box is sealed and slides in contact, dividing the conversion box into four chambers. The chamber located in the upper left is open and communicates with the air inlet chamber. A first fan connecting two chambers is fixedly installed on the plate on the left side of the cross rotating plate. The lower end of the chamber located in the lower left is connected to a low-altitude air inlet pipe. The right side of the chamber located in the upper right is connected to an exhaust pipe. The lower end of the equipment box is provided with a high-altitude air inlet pipe communicating with the air inlet chamber. A second fan is fixedly installed at the connection between the high-altitude air inlet pipe and the air inlet chamber. The upper end and right side of the equipment box are respectively fixedly installed with an air supply pipe communicating with the upper chamber and an external air inlet pipe. Above the partition plate is a switching mechanism that communicates with the connecting port, and inside the upper cavity is a purification mechanism.

[0007] In the aforementioned air quality purification and monitoring equipment for a basketball training hall, an air quality monitor is fixedly installed on the air inlet duct, and the monitoring end of the air quality monitor extends into the high-altitude air inlet duct.

[0008] In the aforementioned air quality purification and monitoring equipment for a basketball training hall, the switching mechanism includes an inclined plate fixedly connected to a partition plate and inclined upward from left to right. The inclined plate has a vent that communicates with the vent. A groove is provided on the inclined plate in front of the vent. A movable plate is slidably connected in the groove. The front end of the movable plate extends out of the equipment box. A first telescopic cylinder is fixedly installed on the right side of the equipment box. The telescopic end of the first telescopic cylinder is fixedly connected to the front end of the movable plate through a connecting plate.

[0009] In the above-mentioned air quality purification and monitoring equipment for basketball training hall, the purification mechanism includes multiple medium-efficiency nylon filters fixedly connected to the upper cavity and inclined upward from left to right. An activated carbon honeycomb plate is provided on the left side of the medium-efficiency nylon filter, and a cylindrical filter is provided on the left side of the activated carbon honeycomb plate. The cylindrical filter includes a rotating disk rotatably connected to a partition plate. Multiple uprights are distributed in a ring at the upper end of the rotating disk. An annular plate is fixedly connected to the upper end of each upright. A HEPA filter screen is fitted over the annular uprights. A rotating tube is connected to the annular plate. The upper end of the rotating tube is rotatably connected to an air supply duct. A third fan is fixedly installed inside the air supply duct, and a drive motor for driving the rotating disk is fixedly installed at the lower end of the partition plate.

[0010] In the aforementioned air quality purification and monitoring equipment for a basketball training hall, an ash discharge port communicating with the ash receiving chamber is provided at the upper end of the partition plate and between the activated carbon honeycomb plate and the inclined plate, and an ash receiving box extending into the ash receiving chamber is inserted at the front end of the equipment box.

[0011] In the aforementioned air quality purification and monitoring equipment for a basketball training hall, a gate valve mechanism is provided inside the external air intake duct. The gate valve mechanism includes a second shaft rotatably connected to the inner walls of the front and rear of the external air intake duct. A rotating gate plate is fixedly sleeved on the second shaft, and the rotating gate plate slides against the inner wall of the external air intake duct.

[0012] In the aforementioned air quality purification and monitoring equipment for a basketball training hall, a synchronous drive mechanism is provided on the right side of the equipment box. The synchronous drive mechanism includes a limiting sleeve fixedly connected to the right side of the equipment box. A gear rod is slidably connected through the limiting sleeve. The front ends of the first shaft and the second shaft extend to both sides of the gear rod and are fixedly sleeved with gears. The two gears mesh with both sides of the gear rod. A second telescopic cylinder for driving the gear rod to rise and fall is fixedly installed on the equipment box.

[0013] In the aforementioned air quality purification and monitoring equipment for a basketball training hall, negative ion generators are installed in both the connecting port and the external air intake duct.

[0014] Compared with existing technologies, the advantages of this invention are: This device employs a multi-layered filtration structure (medium-efficiency nylon filter, activated carbon honeycomb panel, and HEPA filter) to achieve graded filtration of large dust particles, sweat odors, formaldehyde, and fine particulate matter in the air. The rotating design of the cylindrical filter ensures that contaminants adhere evenly to the surface of the HEPA filter, extending its lifespan and improving purification efficiency.

[0015] By separating low-altitude and high-altitude air intake ducts, the equipment can selectively draw in near-ground dust pollutants and high-altitude gaseous pollutants (such as carbon dioxide and formaldehyde). Combined with the intelligent switching function of the conversion box, it achieves efficient collection and treatment of pollutants at different altitudes, significantly improving the purification effect.

[0016] The equipment is equipped with an air quality monitor that can detect the levels of gases such as carbon dioxide in real time and automatically switch between internal and external circulation modes based on the detection results. Through a synchronous drive mechanism that links the rotating cross plate and gate valve mechanism, the purification mode is intelligently switched to ensure that the air quality inside the venue is always at its optimal level.

[0017] The inclined filter and ash discharge port design allow dust particles to automatically slide into the ash collection box, reducing the frequency of manual cleaning and assisting personnel in cleaning and maintenance.

[0018] In summary, the comprehensive design of this invention effectively solves the air quality problem in basketball training halls, and has the advantages of high-efficiency purification, intelligent control and low maintenance costs, and has broad application prospects.

Detailed Implementation

[0021] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0022] Reference Figures 1-10An air quality purification and monitoring device for a basketball training hall includes an equipment box 1. The equipment box 1 has a horizontal partition 2 and a vertical partition 3. The horizontal partition 2 divides the equipment box 1 into an upper cavity and a lower cavity. The vertical partition 3 is located below the horizontal partition 2 and divides the lower cavity from left to right into a dust collection chamber and an air intake chamber. The air intake chamber is used for the intake and collection of air from the training hall, and the dust collection chamber is used for the collection of dust particles. A connecting port 4 is provided on the horizontal partition 2, communicating with the air intake chamber, allowing air to enter the upper cavity through the air intake chamber.

[0023] A conversion box 5 is located in the lower right corner of the equipment box 1. A first shaft 6 is rotatably connected to the center of the front and rear of the conversion box 5. A cross-shaped rotating plate 7 is fixedly sleeved on the first shaft 6. The cross-shaped rotating plate 7 is in sealed sliding contact with the inner wall of the conversion box 5 and divides the conversion box 5 into four chambers. The chamber located in the upper left corner is open and communicates with the air intake chamber. A first fan 8 connecting two chambers is fixedly installed on the plate on the left side of the cross-shaped rotating plate 7. The first fan 8 connects the two corresponding chambers to each other. The cross-shaped rotating plate 7 can rotate inside the conversion box 5, thereby changing the position of the first fan 8. A low-altitude air intake duct 9 is connected to the lower end of the chamber located in the lower left corner. The low-altitude air intake duct 9 is set around the perimeter or corner of the field and is equipped with strip grilles. Since the dust generated by basketball (ground friction, racket dust), sweat odor and other pollutants have a high density and are easily deposited in the near-ground area, the low-altitude air intake duct 9 at a lower position can effectively draw in these high-density polluted air through the first fan 8. The drawn-in polluted air then enters the air intake chamber.

[0024] The upper right cavity is connected to an exhaust duct 10 for exhausting air from the training hall. A high-altitude air intake duct 11, connected to the air intake chamber, is located at the lower end of the equipment box 1. A second fan 12 is fixedly installed at the connection between the high-altitude air intake duct 11 and the air intake chamber. The high-altitude air intake duct 11 is positioned at a higher location within the stadium seating area and sports field. As the flow of people increases and exercise continues, the temperature inside the training hall rises, causing gaseous pollutants such as carbon dioxide and formaldehyde to rise. The high-altitude air intake duct 11 can effectively draw in polluted air that has accumulated at a higher position through the second fan 12. An air supply duct 15, connected to the upper cavity, and an external air intake duct 14, are fixedly installed at the upper end and right side of the equipment box 1, respectively. The air supply duct 15 is located at the top of the training hall and is used to exhaust clean air. The clean air diffuses evenly from the top, avoiding direct airflow onto athletes and causing discomfort. Laminar flow technology can be used to create a top-down airflow pattern covering the entire area. The external air intake duct 14 allows outside air to enter, facilitating ventilation when the training hall is empty or when carbon dioxide levels are too high.

[0025] An air quality monitor 13 is fixedly installed on the air intake duct 11. The monitoring end of the air quality monitor 13 extends into the high-altitude air intake duct 11. The air quality monitor 13 is a prior art technology and can detect the content of various gases in the air. When the carbon dioxide content in the air intake duct 11 is detected to be too high, the equipment can be controlled to perform external circulation ventilation.

[0026] Above the partition plate 2 is a switching mechanism that communicates with the connecting port 4. The switching mechanism includes an inclined plate 25 fixedly connected to the partition plate 2 and inclined upward from left to right. An air vent 26 communicating with the connecting port 4 is opened on the inclined plate 25. A sliding groove is opened on the inclined plate 25 and in front of the air vent 26. A movable plate 27 is slidably connected in the sliding groove. The front end of the movable plate 27 extends out of the equipment box 1. A first telescopic cylinder 28 is fixedly installed on the right side of the equipment box 1. The telescopic end of the first telescopic cylinder 28 is fixedly connected to the front end of the movable plate 27 through a connecting plate 29. The first telescopic cylinder 28 can drive the movable plate 27 to move along the sliding groove, thereby closing or opening the air vent 26.

[0027] Specifically, when the vent 26 is open, the air in the training hall is drawn into the air intake chamber through the high-altitude air intake duct 11 and the low-altitude air intake duct 9, and then enters the upper cavity. Subsequently, it is discharged through the air supply duct 15, thus realizing the internal circulation of air.

[0028] The upper cavity houses a purification mechanism, which includes multiple medium-efficiency nylon filters 18 fixedly connected to the upper cavity and arranged at an upward angle from left to right. These filters are used to filter large particles of dust and hair from the air. The mesh size of the medium-efficiency nylon filters 18 increases from bottom to top, achieving effective pre-filtration. An activated carbon honeycomb panel 17 is located on the left side of the medium-efficiency nylon filters 18 to absorb sweat odor and formaldehyde from the air.

[0029] A cylindrical filter is located on the left side of the activated carbon honeycomb panel 17. The cylindrical filter includes a rotating disk 19 rotatably connected to the partition plate 2. Multiple uprights 20 are arranged in a ring around the upper end of the rotating disk 19, and each upright 20 is fixedly connected to an annular plate 21. A HEPA filter 23 is fitted over the annular uprights 20, effectively filtering fine particles and purifying the air. A rotating pipe 22 is connected to the annular plate 21, and its upper end is rotatably connected to an air supply duct 15. A third fan 24 is fixedly installed inside the air supply duct 15. When the third fan 24 is working, it can create a negative pressure environment inside the cylindrical filter, thereby effectively filtration and purification of the air. A drive motor 30 is fixedly installed at the lower end of the partition plate 2 to drive the rotating disk 19. The drive motor 30 drives the cylindrical filter to rotate, ensuring uniform adhesion of contaminants on the surface of the HEPA filter 23 and improving the service life of the HEPA filter 23.

[0030] A dust discharge port 16, communicating with the dust collection chamber, is provided at the upper end of the partition plate 2, between the activated carbon honeycomb plate 17 and the inclined plate 25. A dust collection box 37 extending into the dust collection chamber is inserted at the front end of the equipment box 1. Specifically, after the air passes through the purification and filtration mechanism in the upper chamber, a large number of dust particles will be attached to the medium-efficiency nylon filter screen 18. When the operation of the first fan, the second fan, and the third fan is stopped, the larger dust particles will fall off under the action of gravity. At this time, the air vent 26 is closed by the first telescopic cylinder 28, so that the surface of the inclined plate 25 forms a complete inclined surface. Then, the dust particles falling from the medium-efficiency nylon filter screen 18 can slide down to the dust discharge port 16 and fall into the dust collection box 37, automatically completing the dust collection.

[0031] Furthermore, by installing doors on the side and rear of the equipment box 1, the dust generated during cleaning of each filter component can be directly discharged into the dust collection box for convenient centralized treatment, thus improving the convenience of maintenance work.

[0032] The external air intake duct 14 is equipped with a gate valve mechanism. The gate valve mechanism includes a second shaft 31 rotatably connected to the inner walls of the front and rear of the external air intake duct 14. A rotating gate plate 32 is fixedly sleeved on the second shaft 31. The rotating gate plate 32 slides against the inner wall of the external air intake duct 14 to close the external air intake duct 14. During internal circulation operation, the external air intake duct 14 is always kept closed.

[0033] A synchronous drive mechanism is provided on the right side of the equipment box 1. The synchronous drive mechanism includes a limiting sleeve 35 fixedly connected to the right side of the equipment box 1. A gear 34 is slidably connected through the limiting sleeve 35. The front ends of the first shaft 6 and the second shaft 31 extend to both sides of the gear 34 and are fixedly sleeved with gears 33. The two gears 33 mesh with both sides of the gear 34. A second telescopic cylinder 36 is fixedly installed on the equipment box 1 to drive the gear 34 to rise and fall. When the second telescopic cylinder 36 drives the gear 34 to move down, it can drive the two gears 33 to rotate relative to each other, and the rotation angle is 90 degrees.

[0034] Specifically, when the air quality monitor 13 detects that the carbon dioxide content in the training hall is too high, it controls the first telescopic cylinder 28 and the second telescopic cylinder 36 to work. The first telescopic cylinder 28 directly blocks the vent 26 to stop the internal circulation. While the second telescopic cylinder 36 drives the rack 34 to move down, it can simultaneously drive the cross rotating plate 7 and the rotating gate 32 to rotate. The cross rotating plate 7 rotates 90 degrees clockwise, so that the first fan 8 rotates to a vertical position, thereby connecting the left and right cavities and connecting the exhaust duct 10 with the air inlet cavity. At the same time, the low-altitude air inlet duct 9 is closed. The air in the middle of the training hall is discharged from the training hall through the high-altitude air inlet duct 11 under the combined action of the first fan 8 and the second fan 12. At the same time, the rotating gate 32 rotates 90 degrees counterclockwise, changing from a vertical to a horizontal state, thereby opening the external air intake duct 14 and connecting the external air intake duct 14 with the upper cavity. Under the suction of the third fan 24, the external air is filtered by the purification mechanism and then directly sent into the training hall through the air supply duct 15, thereby realizing the external circulation of air, effectively reducing the carbon dioxide content in the training hall, and ensuring the comfort and safety of the personnel in the hall.

[0035] Furthermore, the aforementioned external circulation operation can be manually performed when the training hall is unoccupied to exchange the air inside.

[0036] Negative ion generators are installed in both the connecting port 4 and the external air intake duct 14. The negative ion generators can charge and settle particulate matter in the air entering the purification unit. Small particles are agglomerated into larger particles due to static electricity, making them easier to be captured by the filter. At the same time, negative ions simulate the natural environment, neutralize positive ions in the air, reduce the stuffiness of athletes, and improve breathing comfort.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
