Description

Technical Field

[0001] The utility model relates to the technical field of enameled wires, in particular to a salt water spraying test device for an enameled wire stator. Background Art

[0002] Enameled wire is a main type of winding wire, which consists of a conductor and an insulating layer. The bare wire is annealed and softened, then painted and baked several times. Enameled wire stators are widely used in various electrical appliances. However, the working environment of some electrical appliances is very harsh, so the enameled wire stators are required to have certain waterproof insulation properties to ensure that they can achieve the expected service life in harsh working environments.

[0003] The quality characteristics of enameled wires vary, but they all have four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties. In order to test the waterproof insulation performance of the enameled wire and avoid leakage, the enameled wire stator is usually tested by spraying salt water on it.

[0004] The existing spray test devices on the market do not have the function of stirring the brine when in use, which causes the brine to precipitate during use, resulting in a poor test effect on the enameled wire stator. In addition, the used brine is not convenient for secondary use, resulting in a serious waste of water resources. Utility Model Content

[0005] The purpose of the present utility model is to provide a salt water spray test device for an enameled wire stator, so as to solve the problem that the salt water of the existing spray device proposed in the above background technology will precipitate during the spraying process, resulting in a poor test effect on the enameled wire stator, and the used salt water is not convenient for secondary use, resulting in a serious waste of water resources. In order to achieve the above purpose, the present utility model provides the following technical solutions: a salt water spray test device for an enameled wire stator, comprising a base, a water collecting box is fixed on the top of the base, a leak plate is installed in the middle of the water collecting box, a placement table is installed in the middle of the leak plate, an enameled wire stator body is placed in the middle of the placement table, a bracket is installed at the end of the water collecting box, a transfer box is fixed at the bottom of the bracket, the top of the transfer box is connected to a water pipe and a sewer pipe respectively, and the bottom of the transfer box is connected to a spray head;

[0006] The end of the sewer pipe is connected to a brine storage tank, a rotatable stirring rod is provided in the middle of the brine storage tank, a motor is fixed to the side wall of the water collecting tank, a rotating rod is fixedly connected to the output end of the motor, a stirring shaft is fixedly connected to the outside of the rotating rod, and a filter screen that can slide up and down is provided inside the water collecting tank.

[0007] Preferably, a leakage hole is provided at the bottom of the placement table.

[0008] Preferably, the transfer box is connected to the water collecting tank via a water pipe, and the transfer box is connected to the brine storage tank via a downpipe, and supports are provided on the outside of the water pipe and the downpipe.

[0009] Preferably, a driving bevel gear is fixedly sleeved on the end of the rotating rod, a driven bevel gear is meshed on the top of the driving bevel gear, the driven bevel gear is fixedly connected to the stirring rod, and a support plate is sleeved on the outside of the stirring rod.

[0010] Preferably, a support is fixed to the bottom of the salt water storage tank, and the support plate is fixedly connected to the support.

[0011] Preferably, a slide plate is fixed to the end of the filter, a slide rod is fixed to the top of the slide plate, an impact plate is fixed to the top of the slide rod, a spring is sleeved on the outside of the slide rod, a fixed plate is fixed to the side wall of the water collecting tank, the fixed plate is fixedly connected to the spring, the slide rod is slidably connected to the fixed plate, protrusions are fixed at both ends of the fixed plate, a support plate is slidably sleeved on the outside of the protrusion, a cam is fixedly sleeved on the outside of the rotating rod, and the cam and the impact plate slide in the same horizontal plane.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, a starting motor drives the active bevel gear outside the rotating rod to rotate and mesh with the driven bevel gear. The driven bevel gear is forced to drive the stirring rod to rotate in the brine storage box, so that the brine in the brine storage box is stirred to avoid precipitation of the brine and thus affect the subsequent test results.

[0014] In the utility model, when the motor drives the rotating rod to rotate, the cam sleeved on its outside rotates immediately and hits the impact plate. The impact plate is forced to drive the sliding rod to slide down and squeeze the spring. At the same time, the slide plate at the bottom of the sliding rod slides down immediately and drives the filter to slide in the water collecting tank. The cam continues to rotate to fall off the impact plate, and the spring releases the pressure and resets to drive the filter to slide up. As the cam continues to rotate, the filter slides up and down back and forth to filter the brine. The filtered brine is transported to the transfer box through the water pipe for secondary use, thereby reducing the waste of water resources. BRIEF DESCRIPTION OF THE DRAWINGS

Since the water source is controlled by the water valve to deliver water through the sewer pipe 10 and the water pipe 7 for spraying, which is a prior art in the field, it will not be elaborated on.

[0041] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a driving bevel gear 1201 is fixedly sleeved on the end of the rotating rod 14 , a driven bevel gear 1202 is meshed on the top of the driving bevel gear 1201 , the driven bevel gear 1202 is fixedly connected to the stirring rod 12 , and a support plate 1203 is sleeved on the outside of the stirring rod 12 .

[0042] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a support is fixed to the bottom of the salt water storage tank 11, and the support plate 1203 is fixedly connected to the support.

[0043] It should be noted that a support is provided at the bottom of the brine storage tank 11, and the brine storage tank 11 is installed and supported by the support, and a support plate 1203 is provided therein, and the stirring rod 12 rotates in the middle thereof, and the support plate 1203 provides support force for the stirring rod 12 when it rotates, so as to prevent the stirring rod 12 from being subjected to unstable force and thus affecting the stability of stirring.

[0044] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a slide plate 1501 is fixed to the end of the filter 15, a slide bar 1502 is fixed to the top of the slide bar 1501, a strike plate 1505 is fixed to the top of the slide bar 1502, a spring 1504 is sleeved on the outside of the slide bar 1502, a fixed plate 1503 is fixed to the side wall of the water collecting tank 2, the fixed plate 1503 is fixedly connected to the spring 1504, the slide bar 1502 is slidably connected to the fixed plate 1503, protrusions 1506 are fixed at both ends of the fixed plate 1503, a support plate 1507 is slidably sleeved on the outside of the protrusion 1506, a cam 1508 is fixedly sleeved on the outside of the rotating rod 14, and the cam 1508 and the strike plate 1505 slide in the same plane.

[0045] It should be noted that the specific model and specifications of the motor 13 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0046] The use method and advantages of the utility model: When the enameled wire stator salt water spray test device is working, the working process is as follows:

[0047] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the enameled wire stator body 5 to be spray tested is placed on the placement table 4, and then the motor 13 is started to drive the rotating rod 14 to rotate. When the rotating rod 14 rotates, the externally sleeved active bevel gear 1201 rotates and meshes with the driven bevel gear 1202. The driven bevel gear 1202 is driven by the force to drive the stirring rod 12 to rotate in the support plate 1203, so that the stirring rod 12 is placed in the brine storage tank 11 to rotate and stir the brine, thereby avoiding the precipitation of the brine and affecting the subsequent test results;

[0048] The water valve is opened so that the salt water in the salt water storage tank 11 is transported to the transfer box 8 through the downpipe 10 and sprayed out through the spray head 9, so that the salt water is sprayed out to spray the enameled wire stator body 5 for spraying test. At the same time, the sprayed salt water leaks into the water collecting tank 2 through the leak plate 3 for collection, avoiding the waste of water resources caused by direct discharge of water source;

[0049] The motor 13 drives the rotating rod 14 to rotate and drives the cam 1508 sleeved on its outside to rotate immediately. During the rotation of the cam 1508, it hits the impact plate 1505. The impact plate 1505 is forced to drive the sliding rod 1502 to slide down in the fixed plate 1503 and squeeze the spring 1504. At the same time, the protrusions 1506 at both ends of the impact plate 1505 slide in the supporting plate 1507. When the sliding rod 1502 slides down, the sliding plate 1501 immediately drives the filter screen 15 to slide down in the water collecting tank 2. As the cam 1508 continues to rotate and separates from the impact plate 1505, the spring 1504 releases the squeezing force and drives it to reset through its own elastic performance, so that the filter screen 15 slides up. The continuous rotation of the cam 1508 makes the filter screen 15 slide back and forth up and down, and the stirring shaft 1401 outside the rotating rod 14 rotates to stir the brine, so that the brine is evenly filtered, and the filtered brine is transported to the transfer box 8 through the water pipe 7 for secondary use, thereby reducing the waste of water resources.

[0050] The above shows and describes the basic principle, main features and advantages of the utility model.
