Description

Technical Field

[0001] This utility model relates to the field of lamp sealing test, and in particular to a rain test box for train taillights. Background Technology

[0002] Train taillights are a special type of lighting fixture, featuring red and white LED panels located on the front and rear sides respectively. They provide safety signals and directional indications to the drivers of both the lead and following trains, ensuring safe and smooth train operation. Because train taillights are mostly located on the exterior sides of the carriages, almost entirely exposed to the air, they are susceptible to damage from rain, which can lead to leaks or short circuits and ultimately malfunctions, affecting train safety. Therefore, train maintenance personnel need to remove the taillights periodically for inspection to assess their sealing. Traditional inspection methods rely on technicians directly observing whether the taillights light up and turn on normally and whether the seams are intact. This method is inefficient, inaccurate, and cannot simulate the complex environment of rainy weather, failing to accurately test the taillights' performance in actual operation. Utility Model Content

[0003] To overcome the shortcomings of existing train taillight testing methods, the technical problem to be solved by this utility model is to provide a train taillight rain testing box that is highly efficient and can simulate the actual operating conditions of trains.

[0004] The technical solution adopted by this utility model to solve its technical problem is: The train taillight rain test box includes a box-shaped outer shell with an open top. Inside the box-shaped outer shell, a vertical partition divides the space into a test area and an electrical control area. A water pipe with multiple nozzles is located at the top of the test area. A filter plate is located in the lower middle part of the test area, below which is a water storage area. A water pump connected to the water pipe is located in the water storage area. A horizontal support frame is located in the middle of the test area, with multiple rotating shafts spaced along its length. Lamp clips are located at both ends of the rotating shafts, and a driven gear is located in the middle. A rack that slides along the length of the support frame is located in the middle of the support frame, meshing with each driven gear. A drive mechanism for moving the rack back and forth is located in the electrical control area.

[0005] Furthermore, the side wall of the detection area of ​​the box-shaped housing is provided with multiple wiring ports that penetrate the box-shaped housing, and the outer wall of the box-shaped housing is provided with wire grooves that connect the wiring ports to the electrical control area.

[0006] Furthermore, the top opening of the detection area of ​​the box-shaped outer shell is provided with an openable glass cover.

[0007] Furthermore, the nozzle is an adjustable spray opening size nozzle, and the water pump is a power adjustable water pump.

[0008] Furthermore, the bottom side of the detection area of ​​the box-shaped shell is provided with an openable and closable drain outlet.

[0009] Furthermore, the lamp clamp is a U-shaped elastic clamp, and the train taillight is attached to the elastic clamp through a mounting ear on one side.

[0010] Furthermore, the U-shaped opening of the lamp clip is provided with a removable pin.

[0011] Furthermore, the support frame is a long, rectangular box structure with an openable sealing cover at the top. The rotating shaft passes through both sides of the box structure and is rotatably connected to the side wall of the box structure. The driven gear is located inside the box structure, and the rack is slidably connected to the grooves on the inner wall of the box structure on both sides.

[0012] Furthermore, the bottom of the support frame's box structure is provided with multiple drainage holes.

[0013] Furthermore, the support frame extends through the vertical partition into the electrical control area, and the drive mechanism consists of a drive gear mounted on the support frame and meshing with a rack, and a motor mounted on the support frame that drives the drive gear to rotate.

[0014] The beneficial effects of this utility model are as follows: By setting up a spray circulation system inside the box-shaped outer shell to simulate rainfall, and using a rotatable lamp clamp on the support frame to fix the train taillights, the system allows the taillights to rotate within a 360° range to test the sealing performance of various parts of the taillights. The on / off status of the taillights during the test is used to determine whether they are normal. This method has high testing efficiency, guaranteed accuracy, and can truly test the performance of the train taillights in actual operation, thereby eliminating potential water and electrical leakage hazards in the taillights in advance and ensuring the safe and reliable operation of the train.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] It should be noted that if this utility model contains directional indicators such as up, down, left, right, front, and back, these terms are used to describe the relative positional relationships between components and are not specific references to the absolute positions of the components or the relationships between them. They are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indicator will also change accordingly. If this utility model contains terms related to quantity such as "many," "multiple," or "several," these terms specifically refer to two or more.

[0019] like Figure 1 , Figure 2 As shown, the present invention provides a train taillight rain test box, including a box-shaped outer shell 1 with a top opening. The box-shaped outer shell 1 is provided with a vertical partition 2, which divides the shell space into a test area 11 and an electrical control area 12. A water pipe 3 is provided at the top of the test area 11, and multiple nozzles 31 are provided on the water pipe 3. A filter plate 4 is provided in the middle and lower part of the test area 11. Below the filter plate 4 is a water storage area 13. A water pump 5 connected to the water pipe 3 is provided in the water storage area 13. A horizontal support frame 6 is provided in the middle of the test area 11. Multiple rotating shafts 61 are arranged at intervals along the length of the support frame 6. Lamp clips 62 are provided at both ends of the rotating shafts 61, and a driven gear 63 is provided in the middle. A rack 64 that slides along the length of the support frame 6 is provided in the middle of the support frame 6. The rack 64 meshes with each driven gear 63. The electrical control area 12 is provided with a drive mechanism for driving the rack 64 to move back and forth. The electrical control area 12, which houses some controllers required for the lighting fixture testing process, must be completely isolated from the testing area 11 by a vertical partition 2. The drive mechanism can rotate the shaft 61 360° within a single stroke that moves the rack 64 forward or backward.

[0020] The usage process of this utility model is as follows: First, fix the train taillight 8 to be tested on the lamp clamp 62, then connect the power cord to the train taillight 8 to ensure that the train taillight 8 is in a constantly lit state, then start the water pump 5, and use the nozzle 31 to spray the train taillight 8. At the same time, the drive mechanism controls the rack 64 to move back and forth, so that the train taillight 8 rotates back and forth in a 360° range, so that its entire surface can come into contact with the sprayed water. After spraying for a period of time, the presence of water leakage or electrical leakage is determined by whether the train taillight 8 is turned off.

[0021] To facilitate wiring the train taillights 8, multiple wiring ports 14 penetrating the box-shaped housing 1 are provided on the side wall of the detection area 11. A wire trough 15 connecting the wiring ports 14 to the electrical control area 12 is provided on the outer wall of the box-shaped housing 1. The wiring port 14 is a conduit extending into the box-shaped housing 1. The power cord connecting the train taillights 8 is led out from the power supply terminal in the electrical control area 12, passes through the wire trough 15, and extends out from the wiring port 14. When not in use, the power cord can be stored within the wiring port 14 and the wire trough 15. Because a large number of lights are tested at once, to avoid incorrect wiring, one wiring port 14 can correspond to one train taillight 8. Furthermore, to prevent water spray from entering the wiring port 14, an upward-opening flip cover can be provided at the opening of the wiring port 14. After the power cord extends from the wiring port 14, the flip cover can block the opening of the wiring port 14.

[0022] Since it is necessary to observe whether the train taillights 8 are off during the inspection process, an openable glass cover 7 can be installed at the top opening of the inspection area 11 of the box-shaped outer shell 1 to prevent the spray water from splashing outward.

[0023] To simulate the impact of different rainfall amounts on the train taillight 8, the nozzle 31 can be an adjustable spray opening size nozzle, and the water pump 5 can be a power adjustable water pump. During actual testing, the spray size can be adjusted according to the rainfall conditions in different seasons of the train's operating area to closely approximate the actual train operating environment, thereby improving the accuracy of the testing.

[0024] After completing the testing of a batch of lamps, to ensure the long-term stable operation of the equipment, the water in storage area 13 needs to be drained. Therefore, if... Figure 2 As shown, an openable and closable drain outlet 16 is provided on the bottom side of the detection area 11 of the box-shaped outer shell 1.

[0025] Since the train taillights 8 commonly used on trains are mainly fixed to the train via mounting ears 81 on both sides, in order to facilitate the mounting of the taillights 8 by the lamp clips 62, the lamp clips 62 can be configured as a U-shaped elastic clamping structure, such as... Figure 3As shown, the two clamping plates of the lamp clamp 62 have a certain degree of opening and closing elasticity. When the mounting ear 81 of the train taillight 8 is inserted into the clamping plate on the outside of the U-shaped clamping plate, the two clamping plates can clamp and fix the mounting ear 81, thereby preventing it from coming off the lamp clamp 62 during the flipping process. To further ensure the reliability of the clamping, a removable pin 65 can be provided at the U-shaped opening of the lamp clamp 62. After the train taillight 8 is inserted, the pin 65 is inserted to close the opening of the U-shaped clamping plate, which can prevent the train taillight 8 from accidentally falling off.

[0026] Regarding the support frame 6, the preferred embodiment of this utility model is as follows: Figure 1 , Figure 2 As shown, the support frame 6 is a long, rectangular box structure with an openable sealing cover 66 at the top. The rotating shaft 61 passes through both sides of the box structure and is rotatably connected to the side walls of the box structure. The driven gear 63 is located inside the box structure, and the rack 64 is slidably connected to the sliding grooves 67 on the inner wall of the box structure on both sides. To ensure smooth movement between the rack 64, the driven gear 63, and the sliding grooves 67, grease needs to be applied to the contact areas. The box structure of the support frame 6 prevents spray water from entering the support frame 6 and washing away the grease. Of course, some spray water may still enter the support frame 6 through the gap between the support frame 6 and the sealing cover 66 or the rotating shaft 61. Therefore, multiple drainage holes 69 can be provided at the bottom of the box structure of the support frame 6 to drain the ingress spray water. In daily maintenance, the lubrication condition can be checked and grease replenished by periodically opening the sealing cover 66.

[0027] For the drive mechanism, the preferred embodiment of this utility model is that the support frame 6 extends through the vertical partition 2 into the electrical control area 12. The drive mechanism consists of a drive gear 68 mounted on the support frame 6 and meshing with the rack 64, and a motor 9 mounted on the support frame 6 to drive the drive gear 68 to rotate. The motor 9 controls the forward and reverse movement of the rack 64 by driving the drive gear 68 to rotate in both directions. The drive gear 68 can be of the same type as the driven gear 63, so that the drive gear 68 and the driven gear 63 rotate synchronously. Directly controlling the rotation angle of the motor 9 can control the rotation angle of the train taillight 8, which is convenient and quick. To improve the accuracy of angle control, the motor 9 can be a stepper motor or a servo motor.

[0028] This invention simulates rainfall by setting up a spray circulation system inside a box-shaped outer shell. The train taillight 8 is fixed by a rotatable lamp clip 62 on the support frame 6 and rotated within a 360° range to test the sealing performance of the train taillight 8. The on / off status of the train taillight 8 during the test is used to determine whether it is normal. The test is highly efficient and accurate, and can truly test the performance of the train taillight 8 in actual operation, thereby eliminating the hidden dangers of water leakage and electric leakage of the train taillight 8 in advance, ensuring the safe and reliable operation of the train, and has good practicality and application value.
