Description

Technical Field

[0001] This utility model relates to the field of coal mining, specifically to a mine roadway ventilation door system. Background Technology

[0002] In underground coal mine roadways, at the junction of fresh and polluted air, ventilation chambers are typically installed to facilitate pedestrian and vehicle traffic while preventing airflow short-circuiting. These chambers typically have two automatically opening and closing iron doors. When a vehicle needs to pass through, its headlights are repeatedly switched between high and low beams to illuminate a photoelectric sensor on the door. The sensor then sends a signal to a control unit, which opens the first door, allowing the vehicle to enter and wait before the second door. Once the first door is fully closed, the second door opens automatically, allowing the vehicle to pass through. However, due to sometimes short door opening and closing times, low visibility underground, and inaccurate prediction of door opening and closing times by personnel, or vehicles stalling while passing through the door, personnel have been repeatedly injured by the doors, posing a safety hazard.

[0003] According to publicly available patent 202121236818.5, "Mining Roadway Air Door System and Mining Roadway," the system includes a controller, a first air door and a second air door arranged parallel to each other within the air door chamber. Both the first and second air doors are equipped with photoelectric sensors and reminder devices for indicating the remaining opening and closing time of the air doors. One end of the controller is connected to the photoelectric sensor, and the other end is connected to the reminder device. By implementing this invention, reminder devices are installed on both the first and second air doors to remind passersby of the remaining closing time of the first and second air doors, preventing passersby from being trapped due to inaccurate judgment of the door opening and closing time, thus improving safety.

[0004] However, in practice, traditional mine roadway ventilation door systems use reminder devices to inform personnel of the remaining closing time of the first and second ventilation doors. However, relying solely on reminders means that if a vehicle stalls while passing through the ventilation door, the first and second doors will still close, potentially damaging the vehicle. Furthermore, relying on fixed-location reminder devices presents challenges; when a vehicle is not yet close to the door, the limited distance makes it difficult to see the reminders or hear the announcements, which can affect judgment when passing through the ventilation door. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a mine roadway ventilation door system. This system solves the problem that the current traditional mine roadway ventilation door system uses a reminder device to remind the passage personnel of the remaining closing time of the first and second ventilation doors. However, relying solely on reminders means that if a vehicle suddenly stalls while passing through the ventilation door, the first and second ventilation doors will still close, causing damage to the vehicle. Furthermore, relying on a fixed location for the reminder device means that when a vehicle is not close to the ventilation door, the distance may limit the visibility of the reminder device and the ability to hear the announcement, which can easily affect the judgment of passing through the ventilation door.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design a mine roadway ventilation door system, including a ventilation door chamber, wherein a first ventilation door and a second ventilation door are respectively installed on both sides of the interior of the ventilation door chamber, a square groove is opened at the bottom of the interior of the ventilation door chamber, a conveying component is arranged inside the square groove, and a groove is opened on the interior wall of the ventilation door chamber, and a prompting component is installed inside the groove.

[0007] Preferably, the conveying assembly includes a first trough, a second trough, a third trough, a motor, a first rotating roller, a first bearing, a second rotating roller, a second bearing, a conveyor belt, and a support plate.

[0008] Preferably, the first groove is opened on the rear side inside the square groove, a motor is installed inside the first groove, a first rotating roller is connected to the front end of the motor, a conveyor belt is connected to the outside of the first rotating roller, and the rear end of the first rotating roller extends into the second groove opened at the front end inside the square groove and is connected to the first bearing installed in the second groove.

[0009] Preferably, a second rotating roller is connected to the end of the conveyor belt away from the first rotating roller. Both ends of the second rotating roller extend into a third groove located at the front and rear ends of the square groove, and are connected to a second bearing installed in the third groove.

[0010] Preferably, the internal tube of the conveyor belt has a support plate, and square grooves are fixed at both the front and rear ends of the support plate.

[0011] Preferably, the prompting component includes a display screen and a speaker. Multiple display screens are installed in the recess to display the opening and closing times of the first and second air dampers. At the same time, a speaker is installed on the surface of the display screen to announce the opening and closing times of the first and second air dampers.

[0012] Preferably, the inner sides of both the first and second air doors are provided with mounting grooves, and infrared beams are provided inside the mounting grooves.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, through the combination of a square trough and a conveying component, allows the vehicle to be actively moved out of the first or second air door when it malfunctions and stalls while driving inside. This avoids the vehicle being trapped and damaged when the first and second air doors close. It also solves the technical problem of traditional mine roadway air door systems that use reminder devices to inform personnel of the remaining closing time of the first and second air doors. However, if the vehicle stalls while passing through the air door, the first and second air doors will still close, causing damage to the vehicle.

[0015] 2. This utility model, through the combination of a groove and a prompting component, allows for the creation of a long groove on the inner wall of the airlock chamber. A prompting component is then placed inside the groove. By installing multiple displays and speakers within the groove, the driver can continuously observe the sounds played on the displays and speakers at different locations as they pass through the airlock chamber, providing long-distance prompts. This solves the technical problem of relying on fixed-position prompting devices, where, when the vehicle is not close to the airlock, the distance limits the visibility of the prompting device and the sound of the announcements, potentially affecting the driver's judgment when passing through the airlock.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: Mine roadway ventilation door system, see Figures 1 to 3The system includes an airlock chamber 1, with a first airlock 101 and a second airlock 104 installed on both sides inside the airlock chamber 1. A square groove 2 is formed at the bottom of the airlock chamber 1, and a conveying assembly is installed inside the square groove 2. A groove 3 is formed on the inner wall of the airlock chamber 1, and a warning assembly is installed inside the groove 3. When a vehicle malfunctions while traveling through the first airlock 101 and the second airlock 104, a motor 203 can be started during the closing process of the first airlock 101 and the second airlock 104. The motor 203 drives the first rotating roller 204 to rotate, thereby driving the conveyor belt 2. 01. The vehicle is moved directly using the conveyor belt 201, actively removing the stalled vehicle directly from the first air door 101 and the second air door 104. This avoids the vehicle being damaged by the first air door 101 and the second air door 104. This solves the technical problem of traditional mine roadway air door systems that use reminder devices to remind passersby of the remaining closing time of the first air door 101 and the second air door 104. However, if the vehicle stalls while passing through the air door, the first air door 101 and the second air door 104 will still close, causing damage to the vehicle.

[0022] For details, see Figure 2 The conveying assembly includes a first trough 202, a second trough 205, a third trough 208, a motor 203, a first rotating roller 204, a first bearing 206, a second rotating roller 210, a second bearing 209, a conveyor belt 201, and a support plate 207.

[0023] Further, see Figure 2 The first groove 202 is opened on one side of the rear end inside the square groove 2. The motor 203 is installed inside the first groove 202. The front end of the motor 203 is connected to the first rotating roller 204. The first rotating roller 204 is externally connected to the conveyor belt 201. The rear end of the first rotating roller 204 extends into the second groove 205 opened at the front end inside the square groove 2 and is connected to the first bearing 206 installed in the second groove 205.

[0024] It is worth noting that, see Figure 2 The conveyor belt 201 has a second rotating roller 210 connected to the end away from the first rotating roller 204. The front and rear ends of the second rotating roller 210 extend into the third groove 208 opened at the front and rear ends of the square groove 2, and are connected to the second bearing 209 installed in the third groove 208.

[0025] It is worth noting that, see Figure 2 The conveyor belt 201 has an internal support plate 207, and square grooves 2 are fixed at both the front and rear ends of the support plate 207.

[0026] It is worth mentioning that, see Figure 1The notification component includes a display screen 301 and a speaker 302. Multiple displays screens 301 are installed in the recess 3 to display the opening and closing times of the first damper 101 and the second damper 104. Simultaneously, a speaker 302 is mounted on the surface of each display screen 301 to announce the opening and closing times of the first damper 101 and the second damper 104. After connecting the display screen 301 and the speaker 302 to a terminal that controls the opening and closing of the first damper 101 and the second damper 104, the time signal from the terminal can be transmitted to the display screen 301, allowing the display screen 301 to show the closing time of the first damper 101 and the second damper 104. Furthermore, the time signal can also be displayed via the terminal... Multiple speakers 302 play the start times of the first air door 101 and the second air door 104. By setting multiple displays 301 and speakers 302 inside the groove 3, the driver can continuously view the sounds played by the displays 301 and speakers 302 at different positions while passing through the air door chamber 1, thereby providing long-distance prompts to the driver inside the vehicle. This solves the technical problem that when relying on a prompting device set in a fixed position, the prompting device cannot be seen or heard clearly when the vehicle is not close to the air door during the passage of the air door chamber 1 due to distance limitations, which can easily affect the judgment of passing through the air door.

[0027] It is worth emphasizing that, see Figure 3 The inner sides of the first air door 101 and the second air door 104 are provided with mounting grooves 102. An infrared beam 103 is installed inside the mounting groove 102. The infrared beam 103 is connected to the terminal. When the vehicle stalls due to a malfunction while inside the first air door 101 and the second air door 104, the infrared beam 103 can identify that the vehicle is inside the first air door 101 and the second air door 104. The staff can then control the motor 203 to move the vehicle.

[0028] When using the mine roadway ventilation door system, if a vehicle malfunctions while traveling inside the first ventilation door 101 and the second ventilation door 104, the motor 203 can be started during the closing process of the first and second ventilation doors 101 and 104. The motor 203 drives the first rotating roller 204 to rotate, which in turn drives the conveyor belt 201 to move. The conveyor belt 201 directly moves the vehicle, actively removing the malfunctioning vehicle directly from the first and second ventilation doors 101 and 104, thus preventing the vehicle from being damaged by the first and second ventilation doors 101 and 104. After connecting the display screen 301 and the speaker 302 to the terminal for opening and closing the first and second ventilation doors 101 and 104, the time signal of the terminal can be transmitted to the display screen 301. The terminal displays the closing time of the first air door 101 and the second air door 104. Simultaneously, it can play the opening time of the first air door 101 and the second air door 104 through multiple speakers 302. By setting multiple displays 301 and speakers 302 inside the recess 3, the driver can continuously view the sounds played by the displays 301 and speakers 302 at different locations while passing through the air door chamber 1, thus providing long-distance prompts to the driver inside the vehicle. The infrared beam 103 is connected to the terminal. When the vehicle stalls due to a malfunction inside the first air door 101 and the second air door 104, the infrared beam 103 can identify the vehicle's location within these doors, allowing the operator to control the motor 203 to move the vehicle.
