[0002] Lamps are essential items in our daily life. They not only bring us light, but also serve as decoration. Lamps are mainly divided into indoor lamps and outdoor lamps; outdoor lamps mainly include road lamps, landscape lamps, lawn lamps, underground lamps, etc. Since outdoor lamps are often affected by various climatic factors when used outdoors, such as rain, humidity, etc., this may cause them to be damaged. Therefore, it is very important to conduct waterproof testing of lamps to ensure the durability and service life of the lamps.

[0003] The waterproof level is one of the standards for measuring the waterproof performance of lamps. The corresponding waterproof level is selected according to the purpose and environment of the lamp, and verified by professional testing instruments. During the test, the lamp is completely immersed in water for a certain period of time, and then the working state of the lamp and whether water has entered the interior are observed. Confirm the waterproof level based on the test results. If water has entered, it is necessary to check whether the seal of the lamp is tight, or replace the lamp with a higher waterproof level; For example, when testing the waterproofness of lawn lights, different testing equipment is needed to perform rain testing and immersion testing on the lawn lights.

DETAILED DESCRIPTION

[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0015] Embodiment 1: like Figures 1 to 9 As shown, a waterproof performance testing device for lamps according to the present invention comprises a testing box 1; the testing box 1 is provided with a box door 11, and the box door 11 is provided with an observation window 12; The bottom surface of the inner cavity of the detection box 1 is a right-inclined inclined surface; the bottom surface of the inner cavity of the detection box 1 is rotatably connected to a turntable 2; the turntable 2 is driven by a servo motor 21; the turntable 2 is used to install the lawn lamp to be detected; A water inlet 13 is provided on the left wall of the detection box 1; a water outlet 14 is provided on the right wall of the detection box 1; and first hydraulic cylinders 15 are fixedly connected to the left and right end surfaces of the detection box 1; A sealing plate 16 is installed at the bottom of the two first hydraulic cylinders 15, and the two sealing plates 16 seal the water inlet 13 and the water outlet 14 respectively in the initial state; A water tank 3 is installed at the bottom of the detection box 1, and the water tank 3 is used to store water; A water inlet chamber 32 is installed on the left side of the detection box 1; a water pump 31 is installed in the water inlet chamber 32, and a water inlet pipe of the water pump 31 extends into the water tank 3; A water outlet chamber 33 is installed on the right side of the detection box 1, and the water outlet chamber 33 is connected to the water tank 3 through a notch 34; Specifically, when it is necessary to perform an immersion waterproof test on the lawn lamp, first open the box door 11 on the test box 1, then install the lawn lamp on the turntable 2 through bolts, then close the box 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, and the first hydraulic cylinder 15 will drive the sealing plate 16 on one side of the water inlet 13 to move up during the contraction process, when the sealing plate 16 moves up, the water inlet 13 is opened, and then the water in the water inlet chamber 32 enters the test box 1 through the water inlet 13, and at this time the water outlet 14 is closed by the water outlet 14. The sealing plate 16 is sealed, so the water entering the detection box 1 gradually increases, and the liquid level in the detection box 1 gradually rises. When the liquid level in the detection box 1 is higher than the height of the lawn lamp, the water pump 31 is controlled to stop working, and the first hydraulic cylinder 15 is controlled to drive the sealing plate 16 to seal the water inlet 13. At this time, the lawn lamp is immersed in water. After the lawn lamp is immersed for a specified time, the sealing plate 16 at the position of the water outlet 14 is controlled to move up, and then the water outlet 14 is opened, and the water in the detection 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 the lawn lamp is removed from the turntable 2 and the lawn is inspected; More specifically, when it is necessary to test the water resistance of the lawn lamp, first open the box door 11 on the test box 1, then install the lawn lamp on the turntable 2 by bolts, then close the box 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, the first hydraulic cylinder 15 is controlled 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, and then the water in the water inlet chamber 32 will enter the test box 1 through the water inlet 13. Then, the sealing plate 16 controlling the position of the water outlet 14 moves upward, and the water outlet 14 is opened at this time, so that the water flowing into the detection box 1 will flow out from the water outlet 14, so that the detection box 1 presents a state of water flow. In this process, the scene that there is water accumulation on the road surface of the lawn lamp and the impact of the accumulated water flow on the lawn lamp can be simulated. At the same time, the servo motor 21 can be controlled to rotate, and the servo motor 21 will drive the turntable 2 and the lawn lamp on the turntable 2 to rotate. When the lawn lamp rotates to a certain angle, the flowing water can impact different positions of the lawn lamp, so that the waterproofness of the lawn lamp can be more comprehensively tested. Furthermore, when testing the water resistance of lawn lamps under flowing water, water flows of different depths can be simulated to test the lawn lamps. First, the water inlet 13 is controlled to be opened. At this time, water will enter the test box 1, and the depth of the water in the test box 1 will gradually increase. When the water in the test box 1 reaches a certain depth, the water outlet 14 is controlled to be opened. At this time, the water in the test box 1 will flow into the water outlet chamber 33. At the same time, the water in the water inlet chamber 32 continuously enters the test box 1. Therefore, the water in the test box 1 will circulate at a certain depth, thereby simulating the water resistance of the lawn lamp under water flows of different depths.

[0016] Embodiment 2: The first stopper 4 is fixedly connected to the bottom surface of the inner cavity of the detection box 1 on both sides of the water inlet 13, and the first stopper 4 is a right-angled trapezoid; The second stopper 41 is fixedly connected to the bottom surface of the inner cavity of the detection box 1 on both sides of the water outlet 14, and the second stopper 41 is arranged in a mirror image with the first stopper 4; The first and second stoppers 4 and 41 are provided with a partition plate 42 on one side facing the turntable 2; the second hydraulic cylinder 43 is installed on the opposite side of the two partition plates 42, and the other side of the second hydraulic cylinder 43 is installed on the detection box 1; In this embodiment, n-type grooves 44 are provided inside the first stopper 4 and the second stopper 41; the n-type grooves 44 penetrate the bottom end surfaces of the first stopper 4 and the second stopper 41; Each of the n-type grooves 44 is slidably connected with an extension plate 45, and the bottom end surface of the extension plate 45 is in contact with the bottom surface of the inner cavity of the detection box 1; each of the extension plates 45 partially extends out from the n-type groove 44 and is fixedly connected to the adjacent partition plate 42; In this embodiment, evenly arranged through grooves 46 are formed on the bottom surface of the inner cavity of the detection box 1 on the opposite side of the two partitions 42, and the through grooves 46 extend into the water tank 3 and communicate with the water tank 3; A one-way valve is installed in each of the through grooves 46, and the water on the opposite side of the partition 42 will flow into the water tank 3 through the through grooves 46; Specifically, when the lawn lamp is tested for water resistance, the second hydraulic cylinder 43 is controlled to extend, and the second hydraulic cylinder 43 will drive the two partitions 42 to move to the opposite side. Since the extension plate 45 is fixedly connected to the partition 42, during the process of the partition 42 moving to 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, the partition 42 no longer moves. At the same time, since the distance between the partitions 42 becomes smaller, when the lawn lamp is tested for water resistance by immersion and water resistance by flowing water, 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 test box 1 will be located between the two partitions 42, thereby accelerating the height of the liquid level rising and reducing the preparation time before testing the lawn lamp. When the water flows to the water outlet 14, the water will move along the second stopper 41 into the water outlet 14. More specifically, since evenly arranged through grooves 46 are provided on the opposite side of the partition 42, if water flows into the opposite side of the partition 42, the water will flow into the water tank 3 through the through grooves 46. Since a one-way valve is provided in the through grooves 46, the water in the water tank 3 can be prevented from entering the detection box 1 through the through grooves 46.

[0017] Embodiment three: The top of one of the partitions 42 is fixedly connected with evenly arranged mounting blocks 5; each of the mounting blocks 5 is fixedly connected with a first long rod 51; A second long rod 52 is fixedly connected to the partition 42 at the lower right side of the first long rod 51 close to the water outlet 14; each of the first long rod 51 and the second long rod 52 points to another partition 42; Each of the first long rod 51 and the second long rod 52 is provided with a roller 53; the rollers 53 on the plurality of the first long rods 51 all rotate on the first long rods 51; 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; The plurality of rotating rollers 53 are connected to a conveyor belt 6 for co-rotation; the outer ring surface of the conveyor belt 6 is fixedly connected with uniformly arranged arc plates 61; the width of the arc plates 61 is smaller than the width of the conveyor belt 6; On the first long rod 51 close to the second long rod 52, downwardly inclined mounting plates 62 are fixedly connected at both sides of the roller 53; the two mounting plates 62 are rotatably connected to one side of the conveyor belt 6 with a rotating column 63; The conveyor belt 6 passes over two rotating columns 63, and there is a gap between the rotating columns 63 and the arc-shaped plate 61; a filter screen 64 is installed on the water outlet 14; and a delivery port 65 is opened on the top of the detection box 1; In this embodiment, the conveyor belt 6 is a mesh conveyor belt 6; the arc plate 61 is a mesh plate; Specifically, when the lawn lamp is tested for water resistance, the waterproof motor is controlled to rotate, and the waterproof motor drives 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. Since the conveyor belt 6 passes over the rotating column 63, the rotating column 63 can limit the conveyor belt 6 to rotate above the rotating column 63. Since there is a gap between the rotating column 63 and the arc plate 61, the rotation of the conveyor belt 6 will not be affected. At the same time, the inspector puts some branches, leaves or other floating objects into the delivery port 65. When the floating objects fall above the water surface, they will move with the water flow. The moving floating objects will hit the lawn lamp, thereby simulating the situation that when the water flow flows, it will carry some floating objects to hit the lawn lamp. In this process, the scene when the lawn belt encounters water accumulation can be restored more realistically. Since a filter screen 64 is provided on the water outlet 14, when the floating objects flow to 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 The curved plate 61 rotates, and when the curved plate 61 follows the conveyor belt 6 to move to the position of the second long rod 52, the curved plate 61 will move into the water. When the curved plate 61 passes the second long rod 52, the curved plate 61 will contact the filter screen 64, so that the floating objects at the position of the filter screen 64 can be scraped into the curved plate 61, and then the curved plate 61 will drive the floating objects to move. When the curved plate 61 drives the floating objects to move to the position of the water inlet 13, the floating objects will break away from the conveyor belt 6 and fall onto the water surface again, thereby simulating the scene of floating objects impacting the lawn lamp multiple times.

[0018] Embodiment 4: A sealing layer is fixedly connected to the surface of the two sealing plates 16 facing the detection box 1, and the sealing layer is in contact with the side wall of the detection box 1; In this embodiment, the outer surface of the extension plate 45 is also covered with a sealing layer, and the sealing layer is in contact with the n-type groove 44 and the bottom end surface of the inner cavity of the detection box 1; Specifically, since a 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 covered with a sealing layer, and the sealing layer is in contact with the n-type groove 44, water can be prevented from flowing into the n-type groove 44. At the same time, the extension plate 45 and the inner cavity floor of the detection box 1 can be sealed.
