Description

Technical Field

[0001] The present invention relates to the technical field of cooling systems for large buses, and particularly to a rope-driven multi-fan air volume measurement system and a measurement method thereof. Background Art

[0002] With the continuous development of China's transportation industry and the increasing progress of large bus technology, in order to meet the continuously increasing demand for the refrigerating capacity of bus air conditioners, the structural design of large bus air conditioners is also constantly evolving.

[0003] When arranging axial fans on large buses, sometimes due to the influence of vehicle size, the air volume of axial fans, and the size of condensers, it is impossible to arrange the axial fans according to the optimal scheme along the center line. It is necessary to stagger the arrangement of axial fans to save space, or the total size of the fans is not consistent with the total size of the condensers. How to arrange multiple fans to make the best use of the air volume without causing the situation of air grabbing requires corresponding experiments for research. The traditional single-fan test bench cannot meet the design requirements, and it is extremely costly to design a separate housing for each multi-fan arrangement scheme. Therefore, there is a need for an experimental system that can freely change the position of the axial fans to consider the influence of the total air volume when the fans are in different positions, and minimize manual labor as much as possible to facilitate subsequent experiments.

The first sealing film is fixedly connected to one side of the moving direction of the first axial flow fan, the fan support side beam of the first fan support unit, and the fan support beam; the second sealing film is fixedly connected to the other side of the moving direction of the first axial flow fan, the fan support side beam of the first fan support unit, and the fan support beam;

[0111] The second sealing film group includes a third sealing film 42 and a fourth sealing film 43; the third sealing film 42 and the fourth sealing film 43 are respectively used to achieve the sealing between the two sides of the moving direction of the second axial flow fan 41 and the second fan support unit 122.

[0112] The third sealing film and the fourth sealing film are respectively used to seal the two sides of the second axial flow fan on the second fan support unit. The third sealing film is fixedly connected to one side of the moving direction of the second axial flow fan, the fan support side beam and the fan support beam of the second fan support unit; the fourth sealing film is fixedly connected to the other side of the moving direction of the second axial flow fan, the fan support side beam and the fan support beam of the second fan support unit; specifically, in the embodiment of the present invention, the first sealing film and the second sealing film are both conventional plastic films.

[0113] In the embodiment of the present invention, the first sealing film is arranged below the first driving rope group; the second sealing film is arranged below the second driving rope group; the third sealing film is arranged below the third driving rope group; the fourth sealing film is arranged below the fourth driving rope group; such a design can enable the driving rope group to play a role in limiting the sealing film group, preventing the first sealing film, the second sealing film, the third sealing film and the fourth sealing film from bulging due to the action of wind during the operation of the system and affecting the sealing effect.

[0114] Specifically, this embodiment further includes fixing blocks, which are used to assist the first sealing film, the second sealing film, the third sealing film and the fourth sealing film in sealing.

[0115] The air deflector 6 is used to deflect the air flowing through the condensing device 2 and passing through the first fan group and the second fan group.

[0116] In an embodiment of the present invention, when the first axial flow fan 31 and the second axial flow fan 41 rotate forward, cold air output by the condensing device is obtained. At this time, the air deflector is fixedly arranged above the fan support part, and the air flowing through the first axial flow fan 31 and the second axial flow fan 41 is measured for air volume through the air volume measuring instrument arranged above the air deflector after passing through the air deflector.

[0117] In another embodiment, when the first axial flow fan 31 and the second axial flow fan 41 rotate reversely, the air volume is transmitted from the first axial flow fan 31 and the second axial flow fan 41 to the condensing device. At this time, there are two air deflectors in the system, which are respectively fixedly arranged above the two condensing device support parts. At this time, the air flow extracted by the first axial flow fan 31 and the second axial flow fan 41 flows through the condensing device, and is measured for air volume through the air volume measuring instrument 7 arranged above the air deflector after passing through the air deflector; as Figure 5 shown.

[0118] Specifically, by adjusting the inclination angle between the support part of the condensing device and the support part of the fan, the width of the condensing support part is made the same as that of the fan support part. Thus, when the air deflector is arranged above the condensing support part and the fan support part, an air deflector of the same size can be adopted, thereby saving costs.

[0119] The air volume measuring instrument 7 is fixedly arranged on the top of the air deflector 6 and is used for measuring the total air volume passing through the first fan group and the second fan group.

[0120] The present invention also discloses a measuring method for a rope-driven multi-fan air volume measuring system, including the following steps:

[0121] S1: Install the first fan group and the second fan group respectively;

[0122] S2: Start the first rope drive system and the second rope drive system, and adjust the position of the first fan group in the first fan support unit through the first rope drive system, and adjust the position of the second fan group in the second fan support unit through the second rope drive system;

[0123] S3: Install the first sealing film, the second sealing film, the third sealing film and the fourth sealing film 43 respectively, and the fixing block can ensure the flatness and sealing of each sealing film;

[0124] S4: Install the air deflector and the air volume measuring instrument 7 at the air outlets of the first fan group and the second fan group in sequence;

[0125] S5: After ensuring the sealing performance, start the first fan group and the second fan group, and measure the air volume through the air volume measuring instrument 7.

[0126] After the above steps of the present invention, record the air volume of the air volume measuring instrument and the positions of the first fan group and the second fan group in the first fan support unit and the second fan support unit at this time, and repeat S2-S5. After multiple measurements in this way, the positions of the first fan group and the second fan group when the maximum air volume is reached can be obtained, thereby providing a basis for subsequent research.

[0127] A rope-driven multi-fan air volume measuring system and a measuring method thereof according to the present invention are an experimental system considering the influence of the total air volume when the fans are in different positions with respect to each other. Through the design of the first fan group and the second fan group, it can be applied to the air volume measurement in the case of multiple fan positions, greatly reducing the experimental cost. And through the first rope drive system and the second rope drive system, the position of the axial flow fan can be freely changed, and the manual labor can be minimized as much as possible, which is convenient for subsequent experiments. The overall structure is simple, the installation and disassembly are convenient, and the labor cost is low. And by changing the number of axial flow fans, the whole system can be applied to different condenser model lengths to meet the fan measurement requirements in various situations.
