Description

Technical Field

[0001] The invention relates to the technical field of transformer waterproofness detection devices, and in particular to a transformer waterproofness detection device. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. It can be roughly divided into indoor and outdoor installation types. Transformers installed outdoors are also called outdoor transformers, which can be divided into platform installation and pole installation. Outdoor transformers must be able to withstand outdoor climate conditions, so relevant tests are required before leaving the factory.

[0003] When testing the waterproofness of a transformer, water must be sprayed on the transformer surface from multiple angles in order to simulate the outdoor environment. If water is sprayed in only one direction, the final conclusion will not be rigorous enough and cannot be used as a criterion for judgment. Therefore, we propose a transformer waterproofness testing device to solve the above problem. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, such as: it is difficult to implement multi-angle waterproof testing, and to propose a transformer waterproof testing device.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The transformer waterproofness detection device comprises a detection platform and a motor, wherein the output end of the motor passes through the side wall of the detection platform and is fixedly connected with a rotating rod, the end of the rotating rod away from the motor is rotatably connected with the side wall of the detection platform, and two first gears are sleeved on the rotating rod. The upper side of the detection platform is symmetrically fixedly connected with a fixed shell with the midpoint of the detection platform as an axis, and a screw is arranged in the fixed shell, one end of the screw is rotatably connected with the top wall of the fixed shell, and the end of the screw away from the top wall of the fixed shell is fixedly connected with a second gear, and the second gear is meshed with the first gear, and a nut is sleeved on the screw, and one side of the nut is slidably connected with the side wall of the fixed shell, and the fixed shell is opposite to the fixed shell. One side is provided with a sliding groove that runs through the side wall of the fixed shell, and the nut is rotatably connected to a nozzle on the side wall close to the sliding groove, and a support rod is fixedly connected to the lower side wall of the nozzle, and a plurality of springs are fixedly connected to the side of the nut away from the top wall of the fixed shell, and the end of the spring away from the nut is fixedly connected to a limiting plate, and the nut is rotatably connected to a moving rod on the side close to the limiting plate, and the moving rod is rotatably connected to an end away from the nut. The cross bar is slidably connected to the limiting plate, and the side wall of the moving rod is rotatably connected to a horizontal rod, and the horizontal rod runs through the side wall of the fixed shell, and the horizontal rod is fixedly connected to a limiting block on the side close to the nut, and the limiting block is against the support rod.

[0007] Preferably, a weighing platform is provided on the outer side wall of the detection platform, and a transformer is provided on the weighing platform.

[0008] Preferably, the end of the support rod away from the nozzle is rounded.

[0009] Preferably, the limiting plate is in the shape of a circular ring, and the screw rod passes through the circular ring at the center of the limiting plate.

[0010] Preferably, the distance between the nut and the limit plate is greater than the thickness of the weighing platform, and the springs between the nut and the limit plate are distributed in a rectangular shape.

[0011] Preferably, the side wall of the limiting plate is fixedly connected to a limiting rod, and the limiting rod abuts against a side of the moving rod close to the screw rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When the screw rotates and the nut rises, the nozzle will spray downward under the action of the limit block. When the nut drops to a certain extent, the limit plate will drive the spring to contract, so that the limit block is pushed out, thereby raising the nozzle, so that the nozzle can spray different angles of the transformer;

[0014] 2. The spring can not only prevent the nut from colliding with the limit plate and causing damage to the moving rod and the horizontal plate, but also restore the position of the limit block when the nut rises, driving the limit plate to rise. Setting up multiple springs can make the resetting effect better and increase the service life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-2, a transformer waterproofness detection device includes a detection platform 1 and a motor 2. A weighing platform 15 is provided on the outer wall of the detection platform 1. A transformer 16 is provided on the weighing platform 15. The weighing platform 15 can weigh the weight change of the transformer 16 before and after being sprayed with water, so as to detect the waterproof ability. The output end of the motor 2 passes through the side wall of the detection platform 1 and is fixedly connected with a rotating rod 3. The end of the rotating rod 3 away from the motor 2 is rotatably connected to the side wall of the detection platform 1. Two first gears 4 are sleeved on the rotating rod 3. A fixed shell 5 is symmetrically fixedly connected with the midpoint of the detection platform 1 on the upper side of the detection platform 1. A screw 6 is arranged in the fixed shell 5. One end of the screw 6 is rotatably connected to the top wall of the fixed shell 5. The end of the screw 6 away from the top wall of the fixed shell 5 is fixedly connected with a second gear 7. The second gear 7 is meshed with the first gear 4;

[0020] A nut 8 is sleeved on the screw rod 6, and one side of the nut 8 is slidably connected to the side wall of the fixed shell 5. A sliding groove that penetrates the side wall of the fixed shell 5 is opened on the opposite side of the fixed shell 5. A nozzle 9 is rotatably connected to the side wall of the nut 8 close to the sliding groove. A support rod 10 is fixedly connected to the lower side wall of the nozzle 9. The support rod 10 is rounded at one end away from the nozzle 9, and the round head can slide on the surface of the limit block 14 more conveniently. A plurality of springs 11 are fixedly connected to the side of the nut 8 away from the top wall of the fixed shell 5. The spring 11 is fixedly connected to the limit plate 12 at one end away from the nut 8. The distance between the nut 8 and the limit plate 12 is greater than the thickness of the weighing platform 15. The springs 11 between the nut 8 and the limit plate 12 are distributed in a rectangular shape. Multiple springs 11 distributed in a rectangular shape can make the limit plate 12 reset faster and increase the service life of the spring 11. The limit plate 12 is in the shape of a circular ring, and the screw rod 6 passes through the circular ring in the center of the limit plate 12.

[0021] The limit plate 12 does not contact the screw 6, which can make the movement of the limit plate 12 smoother and more conducive to the rapid extension of the limit block 14. The nut 8 is rotatably connected to the side of the limit plate 12 near the limit plate 12, and the side wall of the limit plate 12 is fixedly connected to the limit rod 17. The limit rod 17 and the side of the movement rod 13 near the screw 6 are abutted. The limit rod 17 can prevent the movement rod 13 from moving in the opposite direction and hitting the screw 6 to affect the normal operation of the device. The movement rod 13 is rotatably connected to a cross bar at the end away from the nut 8, and the cross bar is slidably connected to the limit plate 12. The side wall of the movement rod 13 is rotatably connected to a horizontal bar, which penetrates the side wall of the fixed shell 5, and the horizontal bar is fixedly connected to the limit block 14 near the nut 8, and the limit block 14 is abutted against the support rod 10.

[0022] In the present invention, the motor 2 drives the rotating rod to rotate, so that the screw rod 6 rotates, and drives the nut 8 to move. When the limit plate 12 contacts the bottom wall of the fixed shell 5, the moving rod 13 will slide toward the nozzle 9, so that the limit block 14 moves toward the nozzle 9, and the supporting rod 10 against it moves upward, driving the nozzle 9 upward, so that the nozzle 9 can spray to the lower side of the transformer 16, more realistically simulating the outdoor environment of the transformer 16, so that the waterproof ability of the transformer 16 can be tested more accurately, so that the factory standard of the transformer 16 is improved, and then the production quality of the transformer 16 is improved.
