Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically to a high-temperature detection device for deep-buried railway stations. Background Technology

[0002] During the construction of deeply buried railway stations, localized high temperatures are highly likely to occur due to factors such as enclosed spaces, intensive operation of machinery and equipment, and complex geological environments. If such high temperatures are not dealt with in a timely manner, they may cause safety accidents such as heatstroke among construction workers and spontaneous combustion of flammable materials. However, existing high-temperature detection devices used in the construction of tunnels such as deeply buried railway stations have limited functionality; they can only detect the generated high temperatures and cannot automatically cool and ventilate the area after detecting high temperatures.

[0003] Therefore, during the construction of deeply buried stations, cooling requires manual judgment and activation of independent cooling and ventilation equipment, which results in a significant delay. At the same time, the large amount of dust in the construction environment further affects the high-temperature environment, making the working environment of the staff even more harsh. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high temperature detection device for deep-buried stations, so as to solve the problem that the traditional high temperature detection devices for deep-buried stations have only one function, which can only detect high temperature and cannot automatically cool down and ventilate.

[0005] According to an embodiment of this utility model, a high-temperature detection device for a deeply buried railway station includes a ventilation unit installed on the top of a tunnel via multiple sets of mounting components. The ventilation unit includes a main air duct and a blower at the end of the main air duct, as well as multiple detachable extension air ducts. One end of the extension air duct is detachably connected to the main air duct. The detection unit includes a mounting box on the main air duct, a temperature detector on the mounting box, and a main board inside the mounting box. The temperature detector and the blower are electrically connected to the main board. The temperature detector is used to detect the tunnel temperature. The atomizing unit is located in the middle section of the main air duct and is electrically connected to the main board. It is used for atomizing to reduce dust and lower the temperature.

[0006] Compared to existing technologies, this invention offers the following advantages: The temperature detector in the detection unit monitors the tunnel temperature in real time, and the main board, acting as the control core, links temperature detection with ventilation and atomization functions. The main board controls the forward and reverse rotation of the blower to draw in and deliver air. During air delivery, the atomization unit works in conjunction with the blower to cool and remove dust. When the temperature detector detects a high temperature, the main board automatically triggers the blower to operate, delivering airflow through the duct formed by the main air duct and the extended air duct for ventilation and cooling. Simultaneously, the atomization unit is activated, generating atomized water vapor within the main air duct, which diffuses into the tunnel with the airflow, serving both dust reduction and enhanced cooling purposes. Atomization enhances cooling efficiency and improves air quality in the construction environment, reducing the dual hazards of high temperatures and dust to construction workers.

[0007] Preferably, the blower includes a fan, which is located at one end inside the main air duct and is electrically connected to the main board.

[0008] Preferably, the atomizing unit includes an annular tube located in the middle section of the main air duct and a water pump. Multiple atomizing nozzles are evenly distributed on the annular tube, and a water inlet pipe connected to the water pump is also provided on the annular tube. The water pump is located in an external water source and is electrically connected to the main board.

[0009] Preferably, the central axis of each atomizing nozzle forms an angle with the axis of the main air duct.

[0010] Preferably, each mounting assembly includes a mounting bracket for mirroring and holding the pipe, and the two mounting brackets are connected by connecting bolts.

[0011] Preferably, each mounting frame is equipped with a mounting arm, which is connected to the tunnel.

[0012] Preferably, mounting slots are provided at both ends of the main air duct, and a filter plate can be detachably installed in each mounting slot. The fan and the annular pipe are located between the two filter plates.

[0013] Preferably, the main air duct is provided with two buckles, which are located at corresponding mounting slots. Both filter plates are provided with locking teeth, and each buckle is locked onto the corresponding locking teeth.

[0014] Preferably, the mounting box is hinged with a cover plate.

Detailed Implementation

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 5 As shown in the figure, this utility model embodiment proposes a high-temperature detection device for a deep-buried railway station. It includes a ventilation unit, which is installed on the top of the tunnel via multiple sets of mounting components. The ventilation unit includes a main air duct 10 and a blower at the end of the main air duct 10, as well as multiple detachable extension air ducts 20. One end of the extension air duct 20 is detachably connected to the main air duct 10. A detection unit includes a mounting box 50 on the main air duct 10, a temperature detector 52 on the mounting box 50, and a main board 53 inside the mounting box 50. The temperature detector 52 and the blower are electrically connected to the main board 53, and the temperature detector 52 is used to detect the tunnel temperature. A misting unit is located in the middle section of the main air duct 10 and is electrically connected to the main board 53 for misting dust reduction and cooling.

[0024] The detailed working process of this embodiment is as follows: The temperature detector 52 in the detection unit monitors the tunnel temperature in real time. The main board 53, as the control core, links the temperature detection with ventilation and atomization functions. The main board 53 controls the forward and reverse rotation of the blower to draw in air. When air is introduced, it can work with the atomization unit to cool down and remove dust. When the temperature detector 52 detects a high temperature, the main board 53 can automatically trigger the blower to work, and the airflow is transported through the air duct formed by the main air duct 10 and the extended air duct 20 to achieve ventilation and cooling. At the same time, the atomization unit is activated to generate atomized water vapor in the main air duct 10, which is diffused into the tunnel with the airflow, serving both the purpose of dust reduction and enhanced cooling. Atomization enhances the cooling efficiency and improves the air quality of the construction environment, reducing the dual hazards of high temperature and dust to construction personnel.

[0025] The ventilation unit uses multiple sets of detachable extension ducts 20, which, together with the blowers at the ends of the main duct 10, allow for flexible adjustment of the duct length according to the tunnel construction progress. As the tunnel face advances, by increasing the number of extension ducts 20, the ventilation and atomization range can be extended to new construction areas simultaneously, ensuring that high-temperature areas are always within the effective treatment range.

[0026] The motherboard 53 serves as the control core and is connected to an external power supply. It uses a predetermined program to link temperature detection with ventilation and atomization functions. This part is existing technology and will not be described in detail here.

[0027] like Figure 3 As shown, the blower includes a fan 54, which is located at one end inside the main air duct 10 and is electrically connected to the main board 53.

[0028] The detailed working process of this embodiment is as follows: The fan 54, as the power component of the ventilation unit, is located at one end inside the main air duct 10. It can efficiently drive the airflow to flow in the main air duct 10 and the extended air duct 20. By quickly replacing the high-temperature air in the tunnel with wind power, it can directly realize the ventilation and heat dissipation function and provide basic power for cooling.

[0029] The fan 54 is electrically connected to the main board 53, allowing the fan 54 to be controlled in real time by the temperature detection results. When the temperature detector 52 detects that the temperature in the buried station tunnel exceeds the standard, the main board 53 can automatically start the fan 54, so that the ventilation action and the high temperature detection are linked in real time, avoiding the lag of traditional ventilation equipment that requires manual start and stop, and ensuring a rapid response when high temperature occurs.

[0030] like Figure 3 and Figure 4 As shown, the atomizing unit includes an annular tube 41 located in the middle section of the main air duct 10 and a water pump. Multiple atomizing nozzles 42 are evenly distributed on the annular tube 41. A water inlet pipe 40 connected to the water pump is also provided on the annular tube 41. The water pump is located in an external water source and is electrically connected to the main board 53.

[0031] The detailed working process of this embodiment is as follows: The annular pipe 41, equipped with multiple evenly distributed atomizing nozzles 42, is installed in the middle section of the main air duct 10. This allows the atomized water vapor to be evenly integrated into the airflow within the main air duct 10 and diffused to all parts of the tunnel by the wind generated by the ventilation unit, ensuring a wider range and more uniform cooling and dust suppression effect. The water inlet pipe 40 connects the water pump to the annular pipe 41. The water pump draws water from an external water source to provide continuous water support for atomization, ensuring the stable operation of the atomization process.

[0032] The water pump is electrically connected to the main board 53, allowing the atomizing unit to automatically start or stop under the control of the main board 53 based on the tunnel temperature data transmitted by the temperature detector 52. When the tunnel temperature exceeds the standard, the main board 53 can simultaneously trigger the ventilation unit and the atomizing unit, allowing the water vapor generated by atomization to spread rapidly with the help of wind, using the water vapor evaporation to absorb heat and achieve cooling, while adsorbing dust to achieve dust suppression, thus realizing automatic linkage cooling and dust suppression after high temperature is detected.

[0033] like Figure 4 As shown, the central axis of each atomizing nozzle 42 forms an angle with the axis of the main air duct 10.

[0034] The detailed working process of this embodiment is as follows: The angle design makes the atomizing nozzle 42 spray at an angle into the internal space of the main air duct 10. The water vapor sprayed at an angle can cross and impact with the axial airflow generated by the fan 54. The water vapor can come into contact with and mix more fully with the airflow in the air duct, and can cover a larger area when it spreads with the ventilation airflow.

[0035] like Figure 2 As shown, each mounting assembly includes a mounting bracket 30 that mirrors and clamps the pipe, and the two mounting brackets 30 are connected by connecting bolts 33.

[0036] like Figure 2 As shown, each mounting bracket 30 is equipped with a mounting arm 32, which is connected to the tunnel.

[0037] The detailed working process of this embodiment is as follows: The mirror-designed fixing frame 30 can form a symmetrical clamping force from both sides of the pipe, closely adhering to the outer wall of the main air duct 10 or the extended air duct 20. With the fastening effect of the connecting bolts 33, the ventilation unit can be firmly fixed to the top of the tunnel, avoiding loosening of the device due to tunnel construction vibration and airflow impact.

[0038] The detachable structure of the connecting bolt 33 makes the installation, adjustment and subsequent maintenance of the fixing frame 30 more convenient. During construction, the ventilation unit can be quickly positioned and fixed. When the tunnel construction progresses and the device position needs to be adjusted or the extension duct 20 needs to be added or removed, it can also be efficiently disassembled and reassembled to meet the needs of the dynamic construction scenario of the tunnel. This solves the problems of poor flexibility and high adjustment cost of the traditional fixed installation method.

[0039] like Figure 2 As shown, the main air duct 10 has mounting slots 11 at both ends, and each mounting slot 11 can be detachably installed with a filter plate 12. The fan 54 and the annular pipe 41 are both located between the two filter plates 12.

[0040] The detailed working process of this embodiment is as follows: The filter plate 12 can block dust, gravel particles, fiber impurities and other contaminants generated during tunnel construction from entering the main ventilation duct 10. Since the fan 54 and the annular pipe 41 are the core components of ventilation and atomization functions, if impurities directly intrude, it may cause wear on the blades of the fan 54, blockage of the nozzles or blockage of the annular pipe 41, affecting the operating efficiency of the equipment or even causing damage.

[0041] The filter plate 12 is detachably installed in the mounting groove 11, which facilitates regular disassembly, cleaning, or replacement. The tunnel construction environment has a large amount of dust, and the filter plate 12 is prone to dust accumulation and blockage. The detachable design can quickly deal with the blockage problem and avoid the airflow in the main air duct 10 being affected by the failure of the filter plate 12. This solves the problems of difficult maintenance and easy secondary blockage of traditional fixed filter structures.

[0042] like Figure 2 As shown, the main air duct 10 is provided with two buckles 111, which are located at the corresponding mounting slots 11. Both filter plates 12 are provided with locking teeth 121, and each buckle 111 is locked onto the corresponding locking teeth 121.

[0043] The detailed working process of this embodiment is as follows: the snap-fit ​​structure of the buckle 111 and the snap-fit ​​tooth 121 can form a mechanical lock after the filter plate 12 is embedded in the mounting groove 11, so as to avoid the filter plate 12 from loosening or falling off due to vibration during tunnel construction or airflow impact generated by the operation of the fan 54.

[0044] like Figure 2 As shown, a cover plate 51 is hinged to the mounting box 50.

[0045] like Figure 1 As shown, the cover plate 51 is provided with fixing bolts 511 for connecting the mounting box 50.

[0046] The detailed working process of this embodiment is as follows: the cover plate 51 can be opened and closed flexibly through the hinge structure. When closed, it can form a sealed or semi-sealed space to block dust and water vapor in the tunnel. The fixing bolts 511 can firmly lock the cover plate 51 to the mounting box 50 after it is closed, effectively resisting vibration, airflow impact or accidental contact during tunnel construction, and preventing the cover plate 51 from being opened accidentally.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
