Description

Technical Field

[0001] The present invention belongs to the technical field of detection, and specifically relates to a detection device for the waterproof performance of lamps. Background Art

[0002] Lamps are essential items in our daily life. They not only bring us light but also play a decorative role. Lamps are mainly divided into indoor lamps and outdoor lamps; outdoor lamps mainly include road lamps, landscape lamps, lawn lamps, buried lamps, etc. Since outdoor lamps are often affected by various climate factors such as rain and humidity when used outdoors, this may cause their damage. Therefore, it is very important to conduct waterproof detection on lamps to ensure their durability and service life.

[0003] The waterproof grade is one of the standards for measuring the waterproof performance of lamps. Select the corresponding waterproof grade according to the use and environment of the lamp, and verify it through professional testing instruments. During the test, the lamp is completely immersed in water and kept for a certain period of time, and then the working state of the lamp and whether water enters the interior are observed. Confirm the waterproof grade according to the test results. If water enters, it is necessary to check whether the lamp seal is tight or replace the lamp with a higher waterproof grade;

[0004] For example, when detecting the waterproof performance of a lawn lamp, different testing devices are required to conduct rain testing and immersion testing on the lawn lamp.

[0030] The beneficial effects of the present invention are as follows:

[0031] 1. For a lighting fixture waterproof performance detection device described in the present invention, by setting up a detection box, it can simulate the scenario where there is accumulated water on the road surface for a lawn lamp and the impact of the flowing accumulated water on the lawn lamp. At the same time, the rotation of the servo motor can be controlled, and the servo motor will drive the turntable and the lawn lamp on the turntable to rotate. When the lawn lamp rotates by a certain angle, at this time, the flowing water can impact different positions of the lawn lamp, so as to more comprehensively detect the waterproofness of the lawn lamp.

[0032] 2. For a lighting fixture waterproof performance detection device described in the present invention, when detecting the running water waterproofness of the lawn lamp, it can simulate the detection of the lawn lamp with water flows of different depths. First, control the water inlet to open, and at this time, water will enter the detection box, and the depth of the water in the detection box gradually increases. When the water in the detection box reaches a certain depth, at this time, control the water outlet to open, and at this time, the water in the detection box will flow into the water outlet chamber, and at the same time, the water in the water inlet chamber continuously enters the detection box. Therefore, the water in the detection box will show a certain depth of circulating flow, so as to simulate the waterproofness of the lawn lamp under water flows of different depths.

[0033] 3. In the waterproof performance detection device of the lamp of the present invention, the tester puts some branches, leaves or other floating objects into the feeding port. After the floating objects fall above the water surface, they will move along with the water flow. The moving floating objects will hit the lawn lamp, so as to simulate the situation that when the water flow is flowing, it will carry some floating objects to impact the lawn lamp. During this process, the scene when the lawn lamp encounters accumulated water can be more realistically restored. By using the conveyor belt and the arc-shaped plate, when the floating objects are moved to the water inlet position, the scene of the floating objects impacting the lawn lamp can be simulated multiple times.

Detailed implementation manners

[0045] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0046] Embodiment 1:

[0047] As Figures 1 to 9 shown, a kind of lamp waterproof performance detection device of the present invention; includes a detection box 1; a box door 11 is opened on the detection box 1, and an observation window 12 is opened on the box door 11;

[0048] The bottom surface of the inner cavity of the detection box 1 is an inclined surface sloping to the right; a turntable 2 is rotatably connected to the bottom surface of the inner cavity of the detection box 1; the turntable 2 is driven by a servo motor 21; the turntable 2 is used to install the lawn lamp to be detected;

[0049] An inlet 13 is opened on the left side wall of the detection box 1; an outlet 14 is opened on the right side wall of the detection box 1; first hydraulic cylinders 15 are fixedly connected to both left and right end faces of the detection box 1;

[0050] Sealing plates 16 are installed at the bottoms of the two first hydraulic cylinders 15, and the two sealing plates 16 seal the inlet 13 and the outlet 14 respectively in the initial state;

[0051] A water tank 3 is installed at the bottom of the detection box 1, and the water tank 3 is used for storing water;

[0052] An inlet chamber 32 is installed on the left side of the detection box 1; a water pump 31 is installed in the inlet chamber 32, and the inlet pipe of the water pump 31 extends into the water tank 3;

[0053] An outlet chamber 33 is installed on the right side of the detection box 1, and the outlet chamber 33 is communicated with the water tank 3 through a notch 34;

[0054] Specifically, when it is necessary to conduct an immersion waterproofness test on the lawn lamp, first open the door 11 on the test box 1, then install the lawn lamp on the turntable 2 through bolts, then close the door 11, and control the water pump 31 to start. The water pump 31 will pump the water in the water tank 3 into the water inlet chamber 32. When the water enters the water inlet chamber 32, control the first hydraulic cylinder 15 to contract. During the contraction of the first hydraulic cylinder 15, the sealing plate 16 on one side of the water inlet 13 will be driven to move upward. When the sealing plate 16 moves upward, the water inlet 13 is opened at this time. Subsequently, the water in the water inlet chamber 32 will enter the test box 1 through the water inlet 13. At this time, the water outlet 14 is sealed by the sealing plate 16 on one side of the water outlet 14. Therefore, the water entering the test box 1 gradually increases, and the liquid level in the test box 1 gradually rises. When the liquid level height in the test box 1 is higher than the height of the lawn lamp, control the water pump 31 to stop working at this time, and at the same time control the first hydraulic cylinder 15 to drive the sealing plate 16 to seal the water inlet 13. At this time, the lawn lamp is immersed in water. When the lawn lamp is immersed for the specified time, control the sealing plate 16 at the position of the water outlet 14 to move upward at this time, and then the water outlet 14 is opened. The water in the test box 1 will enter the water storage chamber through the water outlet 14, and then enter the water tank 3 again through the notch 34. Then remove the lawn lamp from the turntable 2 and check the lawn lamp;

[0055] More specifically, when it is necessary to conduct a flowing water waterproofness test on the lawn lamp, first open the door 11 on the test box 1, then install the lawn lamp on the turntable 2 through bolts, then close the door 11, and control the water pump 31 to start. The water pump 31 will pump the water in the water tank 3 into the water inlet chamber 32. When the water enters the water inlet chamber 32, control the first hydraulic cylinder 15 to contract. During the contraction of the first hydraulic cylinder 15, the sealing plate 16 on one side of the water inlet 13 will be driven to move upward. When the sealing plate 16 moves upward, the water inlet 13 is opened at this time. Subsequently, the water in the water inlet chamber 32 will enter the test box 1 through the water inlet 13. Then control the sealing plate 16 at the position of the water outlet 14 to move upward. At this time, the water outlet 14 is opened. Therefore, the water flowing into the test box 1 will flow out through the water outlet 14, so that a state of water flow is presented in the test box 1. During this process, it is possible to simulate the scenario where there is accumulated water on the road surface where the lawn lamp is located and the accumulated water flows and impacts the lawn lamp. At the same time, the servo motor 21 can be controlled to rotate. The servo motor 21 will drive the turntable 2 and the lawn lamp on the turntable 2 to rotate. When the lawn lamp rotates a certain angle, the flowing water can impact different positions of the lawn lamp at this time, so that the waterproofness of the lawn lamp can be detected more comprehensively;

[0056] Further, when conducting a running water waterproofness test on the lawn lamp, the water flow at different depths can be simulated to test the lawn lamp. First, control the water inlet 13 to open. At this time, water will enter the test box 1, and the water depth in the test box 1 will gradually increase. When the water in the test box 1 reaches a certain depth, control the water outlet 14 to open. At this time, the water in the test box 1 will flow into the water outlet chamber 33, and at the same time, the water in the water inlet chamber 32 will continuously enter the test box 1. Therefore, the water in the test box 1 will show a certain depth of cyclic flow, so as to simulate the waterproofness of the lawn lamp under water flows at different depths.

[0057] Embodiment 2:

[0058] On both sides of the water inlet 13 at the bottom surface of the inner cavity of the test box 1, first stoppers 4 are fixedly connected, and the first stoppers 4 are right trapezoids;

[0059] On both sides of the water outlet 14 at the bottom surface of the inner cavity of the test box 1, second stoppers 41 are fixedly connected, and the second stoppers 41 are arranged in a mirror image with the first stoppers 4;

[0060] On the side of the two first stoppers 4 and second stoppers 41 facing the turntable 2, partition plates 42 are provided; on the opposite sides of the two partition plates 42, second hydraulic cylinders 43 are installed, and the other sides of the second hydraulic cylinders 43 are installed on the test box 1;

[0061] In this embodiment, n-shaped grooves 44 are opened inside the first stoppers 4 and second stoppers 41; the n-shaped grooves 44 penetrate the bottom end faces of the first stoppers 4 and second stoppers 41;

[0062] In each n-shaped groove 44, an extension plate 45 is slidably connected, and the bottom end face of the extension plate 45 is in contact with the bottom surface of the inner cavity of the test box 1; each extension plate 45 partially extends out of the n-shaped groove 44 and is fixedly connected to the adjacent partition plate 42;

[0063] In this embodiment, on the opposite sides of the two partition plates 42 at the bottom surface of the inner cavity of the test box 1, uniformly arranged through grooves 46 are opened, and the through grooves 46 extend into the water tank 3 and communicate with the water tank 3;

[0064] In each through groove 46, a one-way valve is installed, and the water on the opposite sides of the partition plates 42 will flow into the inside of the water tank 3 through the through grooves 46;

[0065] Specifically, when performing a waterproofness test on the lawn lamp, the second hydraulic cylinder 43 is controlled to extend, and the second hydraulic cylinder 43 will drive the two partitions 42 to move towards the opposite side. Since the extension plate 45 is fixedly connected to the partition 42, during the movement of the partition 42 towards the opposite side, the extension plate 45 will be driven to gradually slide out of the n-shaped groove 44. When the second hydraulic cylinder 43 pushes the partition 42 to move to the limit position, at this time the partition 42 no longer moves. At the same time, since the distance between the partitions 42 becomes smaller, when performing an immersion waterproofness test and a flowing water waterproofness test on the lawn lamp, the water flowing in from the water inlet 13 will flow along the first stopper 4 and then flow into the space between the two partitions 42. At the same time, the water in the detection box 1 will be located between the two partitions 42, thereby accelerating the rising height of the liquid level and reducing the preparation time before testing the lawn lamp. When the water reaches the position of the water outlet 14, the water will move along the second stopper 41 into the water outlet 14;

[0066] More specifically, since the opposite sides of the partition 42 are provided with uniformly arranged through grooves 46, if water flows into the position on the opposite side of the partition 42, the water will flow into the water tank 3 through the through grooves 46. And since a one-way valve is provided in the through grooves 46, it is possible to prevent the water in the water tank 3 from entering the detection box 1 through the through grooves 46.

[0067] Embodiment 3:

[0068] A uniformly arranged mounting block 5 is fixedly connected to the top of one of the partitions 42; a first long rod 51 is fixedly connected to each mounting block 5;

[0069] A second long rod 52 is fixedly connected to the partition 42, right below and to the right of the first long rod 51 near the water outlet 14; each first long rod 51 and second long rod 52 points to the other partition 42;

[0070] A roller 53 is provided on each first long rod 51 and second long rod 52; the rollers 53 on the plurality of first long rods 51 are rotatably mounted on the first long rods 51;

[0071] The roller 53 on the second long rod 52 is fixedly connected to the second long rod 52, and the second long rod 52 is driven by a waterproof motor, and the waterproof motor is installed in the partition 42;

[0072] A conveyor belt 6 is rotatably connected to the plurality of rollers 53; uniformly arranged arc-shaped plates 61 are fixedly connected to the outer circumferential surface of the conveyor belt 6; the width of the arc-shaped plate 61 is smaller than the width of the conveyor belt 6;

[0073] On the first long rod 51 near the second long rod 52, mounting plates 62 inclined downward are fixedly connected to both sides of the roller 53; a rotating column 63 is rotatably connected to one side of the two mounting plates 62 facing the conveyor belt 6;

[0074] The conveyor belt 6 passes above the two rotating columns 63, and there is a spacing between the rotating column 63 and the arc-shaped plate 61; a filter screen 64 is installed on the water outlet 14; a feeding port 65 is opened at the top of the detection box 1;

[0075] In this embodiment, the conveyor belt 6 is a mesh conveyor belt 6; the arc-shaped plate 61 is a mesh plate;

[0076] Specifically, when performing the flowing water waterproofness detection on the lawn lamp, control the waterproof motor to rotate. The waterproof motor will drive the second long rod 52 and the rotating rod on the second long rod 52 to rotate, thereby driving the conveyor belt 6 to rotate counterclockwise in a cycle. Since the conveyor belt 6 passes above the rotating column 63, the rotating column 63 can limit the conveyor belt 6 to rotate above the rotating column 63. Also, since there is a spacing between the rotating column 63 and the arc-shaped plate 61, it will not affect the rotation of the conveyor belt 6;

[0077] At the same time, the tester puts some branches, leaves or other floating objects into the feeding port 65. When the floating objects fall above the water surface, they will move along with the water flow. The moving floating objects will hit the lawn lamp, thereby simulating the situation where when the water flow moves, it will carry some floating objects to impact the lawn lamp. During this process, the scenario when the lawn lamp encounters accumulated water can be more realistically restored. Since a filter screen 64 is provided on the water outlet 14, when the floating objects flow to the position of the water outlet 14, the filter screen 64 can block the floating objects. When the conveyor belt 6 rotates in a cycle, it will drive the arc-shaped plate 61 to rotate. When the arc-shaped plate 61 moves to the position of the second long rod 52 following the conveyor belt 6, at this time, the arc-shaped plate 61 will move into the water. When the arc-shaped plate 61 passes by the second long rod 52, at this time, the arc-shaped plate 61 will contact the filter screen 64, thereby scraping the floating objects located at the position of the filter screen 64 into the arc-shaped plate 61. Subsequently, the arc-shaped plate 61 will drive the floating objects to move. When the arc-shaped plate 61 drives the floating objects to move to the position of the water inlet 13, at this time, the floating objects will break away from the conveyor belt 6 and fall onto the water surface again, thereby simulating the scenario of the floating objects impacting the lawn lamp multiple times.

[0078] Embodiment 4:

[0079] On one side surface of the two closing plates 16 facing the detection box 1, a sealing layer is fixedly connected, and the sealing layer is attached to the side wall of the detection box 1;

[0080] In this embodiment, the outer surface of the extension plate 45 is also coated with a sealing layer, and the sealing layer is attached to the n-shaped groove 44 and is attached to the bottom end surface of the inner cavity of the detection box 1;

[0081] Specifically, since the sealing layer is provided on the sealing plate 16, the water inlet 13 and the water outlet 14 can be sealed. Since the surface of the extension plate 45 is coated with the sealing layer and the sealing layer fits the n-shaped groove 44, water can be prevented from flowing into the n-shaped groove 44, and at the same time, the extension plate 45 and the inner cavity floor of the detection box 1 can be sealed.
