[0002] In the rail transit industry, before rail vehicles are inspected and put into service, they need to be placed in a climate chamber for high and low temperature tests. To simulate the actual operating environment of ground vehicles, the climate chamber is equipped with a solar radiation system to simulate actual solar radiation conditions. In addition, two air conditioning units are installed on the exterior roof of the train. During climate testing, the temperature and humidity in the climate chamber need to meet the test standards.

[0027] This utility model provides a humidity control system, which is installed in the climate chamber of a rail vehicle and can regulate the humidity at the fresh air inlet of the air conditioning unit, thereby ensuring testing accuracy and efficiency. Figure 1 As shown, the humidity control system in this embodiment includes a support, a humidification module, and a humidity sensor. The humidification module is connected to the ceiling of the climate chamber via the support, and the humidity sensor is located at the fresh air inlet of the air conditioning unit and is communicatively or electrically connected to the humidification module. The specific structure of the above-mentioned components of the humidity control system according to this utility model will be described in detail below.

[0028] In this embodiment, the support includes a bottom rail 11 fixedly connected to the roof of the climate chamber. The bottom rail 11 extends along a first direction (the length direction of the rail vehicle). A first base 13 is slidably connected to the bottom rail 11. Specifically, a first slider 12, slidably connected to the bottom rail 11, is provided on the top of the first base 13. The humidification module is located on the bottom of the first base 13 facing the rail vehicle. Thus, the first slider 12 allows the humidification module and the first base 13 to reciprocate synchronously along the first direction, thereby adjusting the position of the humidification module (especially the atomizing component described below) along the length direction of the rail vehicle. It should be noted that the sliding connection between two components via a rail and a corresponding slider is a conventional feature in the mechanical field; therefore, the specific structure and assembly relationship of the bottom rail 11 and the first slider 12 will not be described in detail.

[0029] Furthermore, such as Figures 1 to 2As shown, the humidification module includes a water tank 2 connected to the bottom of the first base 13. In this embodiment, the water tank 2 is made of corrosion-resistant lightweight plastic and is specifically formed into a cuboid structure. A water inlet 22 is formed on its side, and the inlet 22 is connected to a water source via a water pipe to facilitate water injection into the water tank 2. Based on the location of the water tank 2, a booster pump 24 is installed at the water inlet 22 to ensure smooth water flow. Furthermore, a drain outlet 21 is formed at the bottom of the water tank 2. When the water in the water tank 2 has not been used for a long time or when the water tank 2 needs to be cleaned, the water in the water tank 2 can be drained through the drain outlet 21.

[0030] Furthermore, in order to ensure the relative sealing of water tank 2, corresponding solenoid valves (not shown in the figure) are installed at both the inlet 22 and the outlet 21.

[0031] It should be noted that there are no restrictions on the specific connection method between the water tank 2 and the first base 13. For example, the connection between the two can be achieved by screwing. Similarly, there are no restrictions on the specific location of the water tank 2, as long as it can stably provide water to the atomizing components described below.

[0032] In this embodiment, as Figure 1 As shown, the humidification module also includes an atomizing component, which can spray water vapor to adjust the humidity (and temperature) at the fresh air inlet of the air conditioning unit. Specifically, a slide rail 31 is provided on the end face of the first base 13 away from the bottom rail 11. The slide rail 31 extends along a second direction, which is the width direction of the rail vehicle. That is, the slide rail 31 and the bottom rail 11 are arranged in a cross shape. Correspondingly, the support also includes a second base that is slidably connected to the slide rail 31 via a second slider 32. The atomizing component is connected to the second base so that it can reciprocate along the second direction.

[0033] It should be noted that the movement of the first base 13 and the second base can be achieved by driving components such as motors or cylinders, which are conventional driving methods in this field, and therefore will not be described in detail.

[0034] Furthermore, the atomizing component includes a telescopic part corresponding to and connected to the second base. The telescopic part includes a fixed end and a telescopic end corresponding to and connected to the fixed end. The telescopic end is capable of reciprocating along a third direction, which is the height direction of the rail vehicle. Specifically, as... Figure 3 As shown, the telescopic part in this embodiment includes multiple columns 41 (which are formed as fixed ends), and each column 41 extends in a third direction. The first end of each column 41 in the extension direction is rotatably connected to the second base through conventional connecting parts such as bearings, so that the column 41 can rotate relative to the second base. That is to say, the column 41 as a fixed end means that there is no relative displacement between the column 41 and the second base.

[0035] Furthermore, the outer side of the column 41 has external threads; correspondingly, the telescopic part also includes a bracket 42. For example... Figure 4 As shown, the bracket 42 in this embodiment has a main body formed as a frame structure. The side of the main body is provided with collars 423 that are screwed to each column 41 in a one-to-one manner. So when the column 41 rotates, the bracket 42 can reciprocate along the extension direction of the column 41, i.e., the third direction, under the action of the threaded pair. In order to improve the stability of the connection between the bracket 42 and the column 41, the column 41 in this embodiment is formed as a variable diameter structure. That is, the outer diameter of the second end of the column 41 away from the second base is larger than that of the middle section of the column 41, and the external thread is formed in the middle section of the column 41. In this way, the large diameter section of the second end of the column 41 can serve as a limiting structure for the bracket 42 to prevent the bracket 42 from falling out.

[0036] It should be noted that there are no restrictions on the specific specifications of the uprights 41 and the bracket 42; they can be determined according to the actual situation. Furthermore, to ensure the stability of the bracket 42 when moving along a third direction, the states of the multiple uprights 41 must be consistent. For example, multiple uprights 41 need to rotate simultaneously clockwise at the same speed. In this embodiment, the uprights 41 are driven to rotate by corresponding motors, which can be located at the second base plate 33. It should be further noted that the specific form of the telescopic part is not limited to this; for example, the bracket 42 can also be directly driven to reciprocate along a third direction by a drive component with telescopic function, such as a hydraulic cylinder.

[0037] In this embodiment, as Figure 4 As shown, the main body of the bracket 42 has multiple sets of through holes. Each set of through holes includes a first through hole 421 and a second through hole 422 formed at both ends in the width direction of the bracket 42. Corresponding telescopic tubes 51 (specifically, flexible hoses capable of changing length, which are existing components) can be assembled through the corresponding first through hole 421 and second through hole 422. Furthermore, the side of the water tank 2 has water inlets 23 that correspond one-to-one with the telescopic tubes 51. Each telescopic tube 51 also has a solenoid valve 52 and a water pump 53 near its first end in the water tank 2. Thus, water in the water tank 2 can flow smoothly into the corresponding telescopic tube 51. Based on the structural characteristics of the telescopic tube 51, the stability of the connection between the atomizing component and the water tank 2 can be ensured during the movement of the bracket 42. Furthermore, a rigid pipe is connected to the second end of the telescopic tube 51 in its extension direction. Multiple atomizing nozzles 54 are provided on the rigid pipe, which can atomize the water source into water vapor and spray it out, facilitating large-area humidity adjustment and improving testing efficiency.

[0038] In this embodiment, a humidity sensor is installed at the fresh air inlet of the air conditioning unit near the solar radiation system. This humidity sensor is communicatively or electrically connected to a control module (not shown in the figure, but may be a controller including components such as a PCB board), allowing the humidity sensor to transmit its real-time humidity data to the control module. Furthermore, the aforementioned humidification module is also communicatively or electrically connected to the control module. That is, the humidity sensor communicates with or is electrically connected to the humidification module through the control module. Therefore, when the humidity sensor detects that the humidity at the fresh air inlet is lower than a preset value, the control module can activate the humidification module to adjust the humidity at the fresh air inlet.

[0039] It should be noted that all solenoid valves 52, pump components, and drive components in the humidification module can be communicatively or electrically connected to the control module, thereby enabling the control module to control the operation of the humidification module more precisely and flexibly. Controlling the humidification module through data from the humidity sensor is also a conventional technique in this field, and the control logic will not be elaborated further.

[0040] When the humidity sensor detects that the fresh air inlet needs humidification, the control module first adjusts the overall position of the humidification module along the first direction via the first slider 12, then adjusts the position of the atomizing component along the second direction via the second slider 32, and then adjusts the position of the atomizing nozzle 54 along the third direction by rotating the column 41. This multi-stage adjustment ensures the accuracy of the water vapor spray position. After the atomizing nozzle 54 is adjusted to the preset position, the corresponding number of telescopic tubes 51 can be activated according to the value of the humidity sensor. For example, when the humidity is very low, all telescopic tubes 51 can be activated. If the humidity is only slightly lower than the preset value, only one or two solenoid valves 52 and water pumps 53 on the telescopic tubes 51 can be activated.

[0041] When the humidification module adjusts the humidity to meet the test standard, the control module controls the humidification module to reset.

[0042] In this embodiment, the light source of the solar radiation system can be fully utilized, and a self-generating module, namely a photovoltaic energy storage component, can be installed in the climate chamber. This self-generating module can serve as the power source for the aforementioned components.

[0043] According to the humidity control system of this utility model, it is installed in the climate chamber of a rail vehicle via a support. Specifically, the humidity control system includes a humidification module connected to the support, and the humidification module can reciprocate relative to the support in a first direction. Furthermore, the humidification module also includes an atomizing component that can independently reciprocate in a second direction, thereby allowing the atomizing component to be adjusted to the desired humidification location to spray water vapor and regulate the humidity and temperature at the corresponding location. Thus, this system can improve the local humidity environment of the fresh air vent area of ​​the air conditioning unit on the solar radiation side of the roof of the rail vehicle without changing the original testing system of the climate chamber, thereby improving the accuracy and efficiency of thermal testing of the rail vehicle.

[0044] In addition, this system also installs a humidity sensor at the fresh air inlet of the air conditioning unit, which is electrically or communicatively connected to the humidification module. The humidity sensor can detect the humidity at the fresh air inlet in real time, and then flexibly control the operation of the humidification module based on the detected humidity.
