Description

Technical Field

[0001] This utility model belongs to the field of testing equipment technology, specifically relating to a novel fan aging testing device. Background Technology

[0002] Fans are powered machines used to generate airflow for various applications, including climate control and personal thermal comfort, vehicle engine cooling systems, mechanical cooling systems, ventilation, smoke extraction, air separation, dust removal, drying, and providing airflow for fire protection. Currently, after fans are assembled, their performance needs to be tested. During testing, workers manually connect the fans to different testing equipment. To improve efficiency, multiple testing stations need to be set up in parallel in the workshop. However, manual operation can easily lead to deviations in voltage loading time, affecting the consistency of product reliability assessment. Furthermore, the testing process suffers from the problem of using a single voltage condition, making it difficult to simulate the diverse scenarios that fans actually operate in. Summary of the Invention

[0003] In view of the above-mentioned shortcomings in the existing technology, the present invention provides a novel fan aging detection device to solve the problems in the background technology.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a novel fan aging testing device, comprising a frame, a transmission assembly, a dynamic power supply assembly, multiple testing trolleys, and a control system. The transmission assembly includes a circular track and a drive device. The testing trolleys are slidably connected to the circular track, and the drive device drives the testing trolleys to move around the circular track. Each testing trolley includes a mounting frame for placing fans and a power-conducting component for connecting fans. The power-conducting component is connected to a conductive brush fixed on the testing trolley. The dynamic power supply assembly includes a busbar track, which is connected to an external power supply and a voltage regulating module. The busbar track is arranged parallel to the circular track. During the operation of the testing trolley around the circular track, the conductive brushes slide in contact with the busbar track. The control system is used to control the drive device and the dynamic power supply assembly.

[0005] Preferably, a chain is provided inside the annular track. The chain is connected to the testing trolley through a connector. The chain meshes with a sprocket. The sprocket obtains driving force through a driving device. Through the meshing transmission design of the chain and sprocket, the testing trolley moves smoothly and synchronously, avoiding problems such as trolley jamming or deviation caused by uneven power transmission.

[0006] Preferably, a vertical frame is fixed in the middle of the upper surface of the frame, and the annular track and the merging track are set on the vertical frame. The vertical frame structure provides centralized support for the annular track and the merging track, which can simplify the equipment layout and enhance the overall rigidity. At the same time, the vertical frame being set in the middle also leaves some operating space. Furthermore, the support of the annular track and the merging track being set on the vertical frame can also reduce the risk of track deformation, thereby ensuring the stability of long-term operation.

[0007] Preferably, the upper surface of the frame is provided with a detection lane, which surrounds the upright frame. The bottom of the detection trolley is fixed with casters, and the detection trolley is slidably connected to the surface of the detection lane through the casters. The sliding cooperation design between the casters and the detection lane allows for flexible steering while supporting the weight of the detection trolley, reducing moving friction resistance and lowering operating energy consumption.

[0008] Preferably, the conductive brush is a copper conductive brush. The high conductivity and wear resistance of the copper conductive brush maintain the current transmission efficiency between the busbar track and the test trolley, and prevent test interruption due to poor contact.

[0009] Preferably, a stand plate is fixed to one side of the placement rack, the power supply component is a five-hole socket, and the conductive brush is set on the back of the stand plate. The structure design of the five-hole 86 socket can match most fans on the market and is compatible with a variety of fan models.

[0010] Preferably, the control system includes control cabinets located at both ends of the frame. The control cabinets are equipped with several control buttons. The dual control cabinet layout enables multi-point operation of equipment start-up, shutdown, and parameter adjustment, improving human-machine interaction efficiency and meeting the control needs of different workstations.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] 1. The testing trolley is driven by the transmission component to move along the circular track in a cycle. The fan automatically completes the aging test during the rotation process, replacing manual handling and wiring operations. At the same time, multiple testing trolleys can run in parallel. A single set of equipment can replace the traditional multi-station testing mode, which greatly shortens the testing cycle.

[0013] 2. The dynamic power supply component provides stable and adjustable power to the moving fan through the sliding contact between the busbar and the conductive brush. The copper conductive brush ensures stable current transmission, avoids voltage loading time deviations caused by manual wiring, and ensures consistent product reliability assessment.

[0028] like Figure 1-8 As shown, this utility model discloses a novel fan aging testing device, comprising a frame 1, a transmission assembly 2, a dynamic power supply assembly 3, multiple testing trolleys 4, and a control system 5. The transmission assembly 2 includes a circular track 22 and a drive device. The testing trolleys 4 are slidably connected to the circular track 22. The drive device drives the testing trolleys 4 to move around the circular track 22. The testing trolleys 4 include a placement rack 43 for placing fans and a power supply component for connecting fans. The power supply component is connected to a conductive brush 32 fixed on the testing trolleys 4. The dynamic power supply assembly 3 includes a busbar track 31, which is connected to an external power supply and a voltage regulating module. The busbar track 31 is arranged parallel to the circular track 22. During the operation of the testing trolleys 4 around the circular track 22, the conductive brush 32 slides in contact with the busbar track 31. The control system 5 is used to control the drive device and the dynamic power supply assembly 3.

[0029] Reference Figure 1 , Figure 5 and Figure 7 A chain 221 is installed inside the circular track 22. The chain 221 is connected to the testing trolley 4 through a connector. The chain 221 meshes with the sprocket 21. The sprocket 21 obtains driving force through a drive device. The upper part of the circular track 22 is provided with an opening (for the connector to enter). The back of the testing trolley 4 has a connector that can be connected to the chain 221. The sprocket 21 is located at both ends of the frame 1 and obtains driving force through a motor. It can also be connected to a multi-stage reduction gearbox to control the speed.

[0030] Reference Figure 1-4 A vertical frame 11 is fixed in the middle of the upper surface of the frame 1. The vertical frame 11 is composed of multiple support columns. A ring track 22 and a converging track 31 are set on the vertical frame 11. The ring track 22 and the converging track 31 are fixed to the vertical frame 11 by bolts. Both the ring track 22 and the converging track 31 are designed to surround the vertical frame 11. The ring track 22 is located at the lower position of the vertical frame 11, and the converging track 31 is located at the upper position of the vertical frame 11.

[0031] Reference Figure 5The upper surface of the frame 1 is provided with a test lane 12, which surrounds the upright frame 11. The bottom of the test trolley 4 is fixed with casters 44, which are fixed to the four corners of the bottom plate of the test trolley 4 and are slidably connected to the surface of the test lane 12 through rolling contact. In the actual production test process, the test lane 12 is divided into aging test areas. The busbar 31 is connected to a 5KW-0-300V autotransformer. The voltage of the busbar 31 in the corresponding area is adjusted according to the aging test area to meet various test needs.

[0032] Reference Figure 6 The conductive brush 32 is made of copper. The high conductivity and wear resistance of the copper conductive brush can maintain the current transmission efficiency between the busbar track 31 and the test carriage 4, and prevent test interruption due to poor contact.

[0033] Reference Figure 5 A vertical plate 41 is fixed on one side of the placement frame 43. The power supply component is a five-hole 86 socket 42. Each testing trolley 4 is equipped with two five-hole 86 sockets 42. The conductive brush 32 is set on the back of the vertical plate 41. The conductive brush 32 is vertically fixed to the back of the vertical plate 41 by bolts and is electrically connected to the wiring terminal of the five-hole 86 socket 42.

[0034] Reference Figure 1 The control system 5 includes control cabinets located at both ends of the rack 1. The control cabinets are equipped with several control buttons, including a power start button and a power stop button, an aging start button and an aging stop button (to turn on or off the detection of the aging zone), a voltmeter for monitoring the voltage of the detection area, a voltage regulation module, and an emergency stop button.

[0035] The working principle of this invention is as follows: During testing, the operator places the fan to be tested on the placement rack 43 of the testing trolley 4 and inserts the fan's power plug into the five-hole 86 socket 42. The control system 5 activates the drive unit to rotate the sprocket 21, which in turn drives the chain 221 to move within the circular track 22. This allows multiple testing trolleys 4 to move synchronously along the circular track 22. During movement, the casters 44 at the bottom of the testing trolley 4 slide on the testing lane 12. As the testing trolley 4 moves, the conductive brush 32 fixed to it maintains sliding contact with the busbar track 31, allowing external power to continuously supply power to the five-hole 86 socket 42 through the busbar track 31 and the conductive brush 32, thus providing the power required for the aging test of the fan. As chain 21 continues to run, all test carriages 4 will sequentially cycle through the aging zone. Each fan on test carriage 4 will complete one or more rounds of aging tests within the aging zone according to the set voltage and time. Operators can observe the fan's operating status (noise, vibration, motor temperature, whether it stops, etc.) during the aging test or after the fan leaves the aging zone to assess its performance and reliability. Pressing the control button stops the inverter output, simultaneously stopping the drive motor, stopping chain 221, and halting the movement of test carriage 4. At any time, pressing either emergency stop button on the control cabinets at either end will immediately cut off all power to ensure production safety.
