Description

Technical Field

[0001] This utility model belongs to the field of ventilation device technology, and in particular relates to an automatically adjustable ventilation device for the side door of a subway driver's cab. Background Technology

[0002] In subway operating systems, driver's cab ventilation systems are key facilities for ensuring a good working environment for drivers. Most still use relatively traditional ventilation structure designs. These traditional ventilation systems drive airflow through mechanical or natural means. Their core function is to effectively exchange the air inside and outside the driver's cab, thereby regulating indoor temperature and humidity, reducing the concentration of harmful gases and odors, and maintaining stable air quality. They not only provide drivers with the fresh air they need to breathe, but also remove the heat generated in the driver's cab due to equipment operation and personnel activities through air circulation, ensuring that the indoor temperature is within a comfortable range, reducing stuffiness and discomfort, and providing basic working environment protection for drivers.

[0003] However, most subway driver cab ventilation systems still use relatively traditional ventilation structures, and their ventilation volume adjustment usually relies on manual control. This is not only cumbersome to operate, but also cannot make timely and automatic adjustments based on real-time environmental parameters in the driver cab (such as temperature, humidity, air quality, etc.). When the driver is focused on driving, it is difficult to detect changes in ventilation demand in time, resulting in poor ventilation and failing to create a comfortable working environment for the driver.

[0004] To address these issues, we provide an automatically adjustable ventilation device for the side door of a subway driver's cab. Utility Model Content

[0005] The purpose of this utility model is to provide an automatically adjustable ventilation device for the side door of a subway driver's cab. The device automatically controls the first adjusting motor through a controller, which causes the first screw to drive the first grid plate to slide and adjust the air duct opening in the mounting groove behind the ventilator, thus solving the problem of poor ventilation in existing subway driver's cabs.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an automatically adjustable ventilation device for the side door of a subway driver's cab, including a ventilator. The ventilator has multiple equidistant air ducts that run through the front and rear. The back of the ventilator has a rear mounting groove, inside which a first air volume regulator is installed. A rear cover plate is fixedly connected to the back of the rear mounting groove. The bottom of the ventilator has a lower mounting groove that communicates with the air ducts. The lower mounting groove has a second air volume regulator installed inside which a lower cover plate is fixedly connected. A filter is fixedly connected to the back of the rear cover plate. An exhaust assembly is installed at the bottom of the ventilator. The first air volume regulator includes a first grid plate slidably connected to the interior of the rear mounting slot, a first threaded sleeve rotatably connected to the interior of the ventilator, a first screw threaded into the interior of the first threaded sleeve fixedly connected to the side of the first grid plate facing the first threaded sleeve, a first regulating motor fixedly connected to the side of the ventilator, and the first threaded sleeve fixedly connected to the output end of the first regulating motor. The second airflow regulator includes a second grid plate slidably connected inside the lower mounting slot, a second threaded sleeve rotatably connected inside the ventilator, a second screw threaded inside the second threaded sleeve fixedly connected to the side of the second grid plate facing the second threaded sleeve, a second regulating motor fixedly connected to the side of the ventilator, and the second threaded sleeve fixedly connected to the output end of the second regulating motor.

[0007] The present invention is further configured such that the first grid plate is located between the ventilator and the rear cover plate, and the second grid plate is located between the lower cover plate and the ventilator, with both the first grid plate and the second grid plate corresponding to the air duct.

[0008] The present invention is further configured such that the filter includes a filter cover fixedly connected to the back of the rear cover plate, and the interior of the filter cover is filled with an air filter element.

[0009] The present invention is further configured such that the exhaust assembly includes an exhaust pipe fixedly connected to the bottom of the lower cover plate, and the exhaust pipe is connected to the lower mounting groove, and an exhaust fan is installed at one end of the exhaust pipe.

[0010] The present invention is further provided that a filter screen is fixedly connected to the front of the ventilator.

[0011] The present invention is further configured such that a controller electrically connected to the first regulating motor and the second regulating motor is fixedly connected to the side of the ventilator, and the controller is electrically connected to the sensors inside the subway.

[0012] This utility model has the following beneficial effects: 1. This utility model uses sensors inside the subway to monitor environmental parameters such as temperature, humidity, and air quality in the driver's cab in real time and transmits them to the controller. The controller analyzes and processes the data. When insufficient air circulation or environmental parameters not meeting comfort standards are detected, the controller automatically controls the operation of the first and second regulating motors. When air needs to be injected, the first regulating motor drives the first threaded sleeve to rotate, causing the first screw to drive the first grid plate to slide and adjust the air duct opening in the mounting slot behind the ventilator. Similarly, the second regulating motor drives the second grid plate to slide and close the lower opening in the mounting slot below the ventilator, achieving precise control of air volume. When air needs to be exhausted, the first regulating motor closes the rear opening of the air duct and opens the lower opening, starting the exhaust fan to extract stale air, heat, and odors, improving ventilation, creating a comfortable environment, avoiding cumbersome manual adjustments, and improving the timeliness and accuracy of control.

[0013] 2. This utility model can intercept larger dust particles and debris through the filter screen. Subsequently, the air continues to pass through the air duct. When it passes through the filter, the air filter element filled inside the filter cover performs its filtering function, which can intercept small particles, harmful gases and other pollutants in the air, purify the air, thereby effectively reducing the risk of drivers inhaling harmful substances and protecting the drivers' health.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example 1 Please see Figures 1 to 5This utility model is an automatically adjustable ventilation device for the side door of a subway driver's cab, including a ventilator 100. The ventilator 100 has multiple equidistant air ducts 106 running through it from front to back. The back of the ventilator 100 has a rear mounting groove 102. The rear mounting groove 102 has a first air volume regulator 500 inside it. The rear mounting groove 102 has a rear cover plate 103 fixedly connected inside it. The bottom of the ventilator 100 has a lower mounting groove 104 that communicates with the air ducts 106. The lower mounting groove 104 has a second air volume regulator 600 inside it. The lower mounting groove 104 has a lower cover plate 105 fixedly connected inside it. The back of the rear cover plate 103 has a filter 200 fixedly connected. The bottom of the ventilator 100 has an exhaust assembly 300. The first airflow regulator 500 includes a first grid plate 501 slidably connected inside the rear mounting slot 102, a first threaded sleeve 503 rotatably connected inside the ventilator 100, a first screw 502 threaded inside the first threaded sleeve 503 fixedly connected to the side of the first grid plate 501 facing the first threaded sleeve 503, and a first regulating motor 504 fixedly connected to the side of the ventilator 100, and the first threaded sleeve 503 fixedly connected to the output end of the first regulating motor 504. The first regulating motor 504 drives the first threaded sleeve 503 to rotate, and by utilizing the thread transmission principle, the first screw 502 drives the first grid plate 501 to slide smoothly in the mounting slot, thereby precisely adjusting the opening size of the air duct 106 and realizing fine control of the airflow. The second airflow regulator 600 includes a second grid plate 601 slidably connected inside the lower mounting groove 104, a second threaded sleeve 603 rotatably connected inside the ventilator 100, a second screw 602 threaded inside the second threaded sleeve 603 fixedly connected to the side of the second grid plate 601 facing the second threaded sleeve 603, and a second regulating motor 604 fixedly connected to the side of the ventilator 100, and the second threaded sleeve 603 fixedly connected to the output end of the second regulating motor 604; The exhaust assembly 300 includes an exhaust pipe 301 fixedly connected to the bottom of the lower cover plate 105, and the exhaust pipe 301 is connected to the lower mounting groove 104. An exhaust fan 302 is installed at one end of the exhaust pipe 301, which can exhaust the air in the driver's cab, thereby promoting air circulation.

[0023] Specifically, the first grid plate 501 is located between the ventilator 100 and the rear cover plate 103, and the second grid plate 601 is located between the lower cover plate 105 and the ventilator 100. Both the first grid plate 501 and the second grid plate 601 correspond to the air duct 106.

[0024] Furthermore, a controller 400 is fixedly connected to the side of the ventilator 100 and electrically connected to the first regulating motor 504 and the second regulating motor 604. The controller 400 is also electrically connected to the sensors inside the subway. By interacting with the sensors inside the subway in real time, the controller 400 can sense environmental parameters such as temperature, humidity, and air quality in the driver's cab and automatically control the operation of the first regulating motor 504 and the second regulating motor 604 to achieve fully automated adjustment of the ventilation device without manual intervention. This greatly improves the timeliness and accuracy of ventilation control and creates a comfortable and healthy working environment for the driver.

[0025] The operation process of this embodiment is as follows: When the subway is running, the sensors in the subway will monitor environmental parameters such as temperature, humidity and air quality in the driver's cab in real time and transmit the data to the controller 400. The controller 400 analyzes and processes the data. When it detects that the air circulation in the driver's cab is insufficient or the environmental parameters do not meet the comfort standard, it will automatically control the first regulating motor 504 and the second regulating motor 604 to operate. When air needs to be injected into the subway, the first adjusting motor 504 drives the first threaded sleeve 503 to rotate. Based on the threaded transmission principle, the first screw 502, which is threadedly connected to the first threaded sleeve 503, drives the first grid plate 501 to slide smoothly in the rear mounting groove 102 of the ventilator 100, thereby precisely adjusting the opening size of the air duct 106. Similarly, when the second adjusting motor 604 is running, the second threaded sleeve 603 drives the second screw 602, causing the second grid plate 601 to slide in the lower mounting groove 104 of the ventilator 100, thereby closing the lower opening of the control air duct 106. This allows for precise control of the air volume entering the driver's cab, effectively improving the ventilation in the driver's cab, creating a more comfortable working environment for the driver, and avoiding the tediousness of frequent manual adjustments, thus improving the timeliness and accuracy of ventilation control. When air needs to be exhausted to the outside, the first regulating motor 504 closes the opening at the rear of the air duct 106 and opens the opening at the bottom of the air duct 106. Then the exhaust fan 302 is started, and the exhaust fan 302 draws out the air from the driver's cab, thereby removing the stale air, heat and any possible odors from the driver's cab, further improving the ventilation effect and keeping the air in the driver's cab fresh.

[0026] Example 2 Please see Figure 3 Based on the first specific embodiment, the filter 200 includes a filter cover 201 fixedly connected to the back of the rear cover plate 103. The filter cover 201 is filled with an air filter element 202. The air filter element 202 has high-efficiency filtration performance, which can intercept pollutants such as tiny particles and harmful gases in the air, effectively purify the air entering the driver's cab, reduce the risk of the driver inhaling harmful substances, and protect the driver's health.

[0027] Specifically, a filter 101 is fixedly connected to the front of the ventilator 100. As the first line of defense of the ventilation device, the filter 101 can block larger dust and debris, prevent them from entering the interior of the ventilator 100, reduce the filtration burden of the air filter element 202, extend the replacement cycle of the air filter element 202, and reduce maintenance costs.

[0028] The operation process of this embodiment is as follows: When outside air enters the ventilator 100, it first passes through the filter 101 fixedly connected to the front of the ventilator 100. The filter 101 can intercept larger dust particles, debris, etc. Subsequently, the air continues to pass through the air duct 106. When it passes through the filter 200, the air filter element 202 filled inside the filter cover 201 performs its filtering function, which can intercept pollutants such as tiny particles and harmful gases in the air, purify the air, thereby effectively reducing the risk of the driver inhaling harmful substances and protecting the driver's health.
