Description

Technical Field

[0001] The invention relates to the technical field of plug rain testing, in particular to a rain testing device. Background Art

[0002] The main purpose of the plug rain test is to observe whether the plug will cause dangerous situations such as circuit short circuit, electric sparks or electric shock after being splashed with water or rain. This helps to evaluate the electrical performance and safety of the plug in a humid environment.

[0003] When using the existing rain test device, the plug and socket are inserted together and placed on the placement rack of the test device, and then water is sprayed on the plug and socket using a swing tube and a nozzle. However, when the plug and socket are placed on the placement rack, the swing direction of the swing tube is fixed, which will result in only the top and two sides of the plug and socket being directly impacted by the simulated rain sprayed from the nozzle, while the outdoor rain will be blown from all sides of the plug and socket due to the influence of the wind, thereby causing a certain deviation between the experimental test effect and the situation when used outdoors.

A through hole 34 is provided on the sleeve 33, and the outer side of the connecting shaft 16 is symmetrically provided with evenly distributed limiting holes 35, which are matched with the through holes 34, and a fixing bolt 36 is provided in the through hole 34, and the sleeve 33 is fixed on the connecting shaft 16 by the fixing bolt 36; The principle of the linkage assembly 15 transmitting the power of the fixed shaft 12 to the rotating shaft 10: First, the rotation of the fixed shaft 12 drives the swing tube 3 to swing forward. At the same time, the fixed shaft 12 drives the connecting shaft 16 to rotate through the mutual cooperation of the gear 1 17, the toothed belt 19 and the gear 2 18, and the connecting shaft 16 drives the supporting wheel 22 to rotate. At this time, the limit block 26 in the bevel gear 1 31 is against the limit groove 23 of the bevel gear 1 31, driving the bevel gear 1 31 to rotate. At this time, the limit block 26 in the bevel gear 3 21 is pressed into the annular groove 24, and the rotating shaft is driven through the meshing of the bevel gear 1 31 and the bevel gear 2 32. 10 rotates, thereby driving the support frame 8 and the plug and socket fixed on the support frame 8 to rotate together; when the swing tube 3 swings backward, the fixed shaft 12 drives the connecting shaft 16 to rotate in the opposite direction, thereby driving the support wheel 22 to rotate in the opposite direction, at this time, the limit block 26 in the bevel gear 1 31 is pressed and retracted into the annular groove 24, and the limit block 26 in the bevel gear 3 21 is pressed into the limit groove 23 of the bevel gear 3 21, driving the bevel gear 3 21 to rotate, thereby driving the rotating shaft 10 to rotate through the meshing of the bevel gear 3 21 and the bevel gear 2 32, thereby driving the support frame 8 and the plug and socket fixed on the support frame 8 to rotate together; In the present technical solution, since the limiting grooves 23 arranged in the bevel gear 1 31 and the bevel gear 3 21 are in opposite directions, when the swing pipe 3 swings back and forth, the connecting shaft 16 can drive the rotating shaft 10 and the support frame 8 to always rotate in one direction through the engagement of the bevel gear 1 31 or the bevel gear 3 21 with the bevel gear 2 32, thereby ensuring that the water sprayed from the nozzle 7 on the swing pipe 3 can be evenly hit on the plug and socket on the support frame 8; At the same time, in the present technical solution, the bevel gear 2 32 and the rotating shaft 10 are fixed together by the flange plate 29, so that the bevel gear 2 32 can be easily replaced. Furthermore, the support wheel 22 is driven to slide on the connecting shaft 16 by the sleeve 33, and the sleeve 33 is fixed in the specified limiting hole 35 on the connecting shaft 16 by the fixing bolt 2 36, so that the positions of the bevel gear 1 31 and the bevel gear 3 21 can be adjusted. When the distance between the bevel gear 1 31 and the bevel gear 3 21 increases, a larger bevel gear 2 32 is fixed at the bottom of the rotating shaft 10. At this time, the bevel gear 2 32 is driven to rotate by the bevel gear 1 31 or the bevel gear 3 21, so that the rotating shaft 10 can drive the support frame 8 to rotate slower when the speed of the connecting shaft 16 remains unchanged. On the contrary, the rotating shaft 10 can drive the support frame 8 to rotate faster, so that the rotation speed of the support frame 8 can be adjusted according to the test requirements. In the present technical solution, the rotation of the rotating shaft 10 and the supporting frame 8 is achieved through the mechanical cooperation of the fixed shaft 12 and the linkage assembly 15 that drives the swing tube 3 to swing. This solution can reduce the use of electrical components, thereby preventing the device itself from causing electric shock such as circuit short circuits and electric sparks due to the use of too many electrical components during the rain test.

[0023] At the same time, reference Fig. 9 In order to place the test paper 14 in the socket, a circularly distributed fracture opening 37 is provided in the middle of the test paper 14, and the circularly distributed fracture opening 37 matches the size of the socket of the socket. Further, the test paper 14 is a moisture detection test paper 14; When the plug and socket are connected, the test paper 14 is placed between the plug and the socket, and the plug is inserted into the socket. The plug squeezes the middle part of the test paper 14, and the test paper 14 is squeezed and breaks at the fracture 37. Then the plug enters the socket with the part of the test paper 14 that matches the socket of the socket. After the rain test, it is possible to determine whether the connection between the plug and socket is tight and waterproof by observing whether the test paper 14 in the socket changes color. This test method can reduce the use of electrical components such as sensors, thereby measuring whether the connection between the plug and socket is tight and waterproof when no power is supplied, thereby reducing the occurrence of electric shock such as electric sparks caused by short circuits when the plug and socket are powered on or electrical components such as sensors are set between the plug and socket when encountering water.

[0024] In this solution, first, the test paper 14 is placed between the plug and the socket, and the plug is inserted into the socket. The plug squeezes the middle of the annular fracture 37 of the test paper 14, and the test paper 14 is cut off from the fracture 37 by the pressure of the plug. Then, the plug enters the socket with the test paper 14 that matches the socket of the socket, and the remaining test paper 14 is removed from the plug and socket, and then the plug and socket are fixed on the support frame 8; Then, the position of the support wheel 22 on the connecting shaft 16 is adjusted by the sleeve 33, so that the two support wheels 22 are symmetrically arranged on both sides of the rotating shaft 10. After the position of the support wheel 22 is determined, the sleeve 33 and the support wheel 22 are fixed on the connecting shaft 16 by inserting the fixing bolt 2 36 into the through hole 34 and the limiting hole 35, so as to fix the positions of the bevel gear 1 31 and the bevel gear 3 21. Then, the bevel gear 2 32 of the corresponding size is fixed to the bottom of the rotating shaft 10 through the flange plate 29. At this time, the bevel gear 2 32 is meshed with the bevel gear 1 31 and the bevel gear 3 21 at the same time, and the bevel gear 1 31 and the bevel gear 3 21 are respectively arranged on both sides of the bevel gear 2 32; Afterwards, the door of the experimental box body 1 is closed, and the driving motor 11 is started through the operator 2. The driving motor 11 drives the fixed shaft 12 to rotate, and then drives the swing pipe 3 to rotate through the mounting plate 13. The electromagnetic pump 5 is started through the operator 2, and the electromagnetic pump 5 sucks water from the external water source through the water inlet pipe 6, and then pumps it into the swing pipe 3 through the water outlet pipe 4, and finally sprays it to the plug and socket on the support frame 8 through the nozzle 7; In the process of the fixed shaft 12 swinging forward with the swing tube 3, the fixed shaft 12 drives the connecting shaft 16 to rotate through the cooperation of the gear 1 17, the toothed belt 19 and the gear 2 18, and the connecting shaft 16 drives the supporting wheel 22 to rotate. At this time, the limit block 26 in the bevel gear 1 31 is pressed against the limit groove 23 of the bevel gear 1 31, driving the bevel gear 1 31 to rotate together with the supporting wheel 22 and the connecting shaft 16. At this time, the limit block 26 in the bevel gear 3 21 is pressed into the annular groove 24, and the bevel gear 3 21 will not rotate with the supporting wheel 22. Then, the rotating shaft 10 is driven to rotate through the meshing of the bevel gear 1 31 and the bevel gear 2 32, thereby driving the support frame 8 and the fixed shaft 10 on the support frame 8. When the swing tube 3 swings backward, the fixed shaft 12 drives the connecting shaft 16 to rotate in the opposite direction, thereby driving the supporting wheel 22 to rotate in the opposite direction. At this time, the limit block 26 in the bevel gear 1 31 is pressed and retracted into the annular groove 24, and the bevel gear 1 31 no longer rotates with the supporting wheel 22 and the connecting shaft 16. Instead, the limit block 26 in the bevel gear 3 21 abuts against the limit groove 23 of the bevel gear 3 21, driving the bevel gear 3 21 to rotate with the supporting wheel 22 and the connecting shaft 16, thereby driving the rotating shaft 10 to rotate through the meshing of the bevel gear 3 21 and the bevel gear 2 32, thereby driving the supporting frame 8 and the plug and socket fixed on the supporting frame 8 to rotate together; Since bevel gear one 31 and bevel gear three 21 are symmetrically arranged on both sides of bevel gear two 32, and the directions of the limit grooves 23 in bevel gear one 31 and bevel gear two 32 are opposite, when the connecting shaft 16 drives bevel gear one 31 and bevel gear three 21 to rotate respectively, the connecting shaft 16 can drive bevel gear two 32 and the rotating shaft 10 to rotate in the same direction all the time, so that the plug and socket on the support frame 8 will not swing left and right with the swing of the swing tube 3, but will rotate in one direction all the time, thereby ensuring that the nozzle 7 can spray water evenly around the plug and socket to simulate the real rain impact situation outdoors.

[0025] Embodiment 2: This embodiment further explains the embodiment 1, and the difference lies in the optimization of the driving motor 11; Specifically, the driving motor 11 uses a servo motor or a stepper motor to achieve more precise angle and speed control, and adjust the swing amplitude of the swing tube 3 as needed. The stepper motor and the servo motor have the advantages of fast response speed, accurate positioning, and smooth operation.

[0026] Embodiment 3: This embodiment further explains the embodiment 1, and the difference lies in the optimization of gear 1 17, gear 2 18 and toothed belt 19; Specifically, Figure 3 and Figure 4As shown, a protective box 38 is provided on the outside of gear 17, gear 2 18 and toothed belt 19. In addition, in the present technical solution, the fixed shaft 12 and the connecting shaft 16 are rotatably connected to the protective box 38, and the bevel gear 1 31, bevel gear 2 32, bevel gear 3 21, the connecting piece 20 and the adjusting piece 28 are all arranged in the installation box 9. Furthermore, an operation port 39 is provided on the front of the installation box 9, and a baffle 40 is slidably provided in the operation port 39. The top of the baffle 40 passes through the top of the installation box 9, and a sealing plate is fixedly provided on the top of the baffle 40. A sealing groove 41 is fixedly provided in the operation port 39, and the outer side of the baffle 40 is sealed and connected to the sealing groove 41. The baffle 40 is used to close the installation box 9, and the additional provision of the protective box 38 can protect the connecting elements such as gears, reduce the speed at which the connecting elements such as gears are corroded by water, and increase their service life.
