[0002] Waterproof transformers are transformers with waterproof (moisture-proof / rain-proof) functions. They have a special protective outer shell (outer cover), and the internal transformer is potted (generally thermally conductive epoxy resin is used as the potting material). They can cope with harsh environments such as high temperature, humidity, rain, and water immersion, and have a high IP protection level (IP67). When used outdoors, environmental factors vary greatly and must have good heat dissipation performance, high temperature resistance, cold resistance, and UV resistance. Considering outdoor construction and installation, overload and short-circuit protection are generally required. Waterproof transformers have been widely used in industries such as outdoor lighting, urban lighting projects, mining areas and mines, ship equipment, electronic bathroom equipment, industrial atomizing humidifiers, medical equipment, and precision instruments.

[0004] When an iron shell is used as a protective shell, some parts may be deformed and thinned during the stamping process of production. The deformation at that part may cause breakage and damage at that part under continuous external pressure during subsequent use. The damage at that part may not be known during the production process. Therefore, a device is needed to detect the waterproof performance of the shell, so as to know the weak points of the shell and then modify the mold to obtain a protective shell with better waterproof performance.

When the box cover is closed at the box opening, the fixing column can be connected to the fixing groove on the fixing seat by rotation.
[0009] The water pump assembly is connected to the detection hole, and the detection assembly includes a display controller and a detection head. The display controller is arranged on the outer wall of the box, and the detection head is arranged at the top of the detection cavity. The display controller is electrically connected to the detection head. The water pump assembly includes a connecting plate, a water inlet pipe and a booster. The upper end of the water inlet pipe passes through the connecting plate, and the connecting plate is detachably connected to the bottom of the box.

[0010] The transformer housing waterproof performance detection information collection device adopts this structure. The detection cavity in the box body forms a relatively closed space after being covered by the box cover. In order to detect the waterproof performance of the shell, a detection hole penetrating the detection cavity is opened at the bottom of the box body. The shell is placed on the detection hole, and water is pumped into the shell to detect the waterproof performance of the shell. A detection head is provided at the top of the detection cavity. The humidity change in the detection cavity, the appearance change of the cover body, the air pressure change and other changes can be detected by humidity detection, video detection, air pressure detection, etc., to detect whether the shell is slightly damaged due to water mist spray, which changes the air humidity in the detection cavity, or because the shell is damaged externally and it can be clearly seen from the appearance, so it can be judged from the camera image, or because a large amount of water flow is pressed into the detection cavity, causing the air in the detection cavity to be compressed, thereby changing the air pressure in the detection cavity. Therefore, the detection head can effectively detect and collect the environmental change information in the detection cavity, and then feed back this information to the display controller for the operator to collect and store, so that a detection report can be issued for the R&D personnel to modify the mold to improve the weak parts of the shell.
[0011] In order to ensure that the shell can be pressed tightly against the detection hole, water can be prevented from flowing out from the gap where the shell and the detection chamber abut against each other when water is pumped in, thereby affecting the detection data. Therefore, a fastening component is provided, which consists of two sets of engaging grooves correspondingly and parallelly arranged at the bottom of the detection chamber. The notches on the two sets of engaging grooves form a clamping portion. The notch is a trumpet-shaped structure that gradually enlarges toward the opening of the box body when viewed from the side. The notch is a structure that gradually shrinks near the opening of the box body. The latter half of the notch is a straight structure, and the edge extensions at both ends of the shell cooperate with the clamping portion. Therefore, when the shell is inserted into the fastening component from the clamping portion, it is loose at first, which is convenient for the staff to pre-insert and guide the shell. After being pushed into the interior of the clamping portion, when it abuts against the latter half of the notch, the extension will gradually be pressed, so that the shell is pressed tightly under the two sets of engaging grooves, so that the shell can be pressed tightly against the detection hole.
[0012] Since the shell is provided with wiring holes at the front and rear ends due to usage needs, the wiring holes also need to be sealed to ensure that the internal space of the shell is in a closed state. Therefore, a sealing component is provided, and a support plate is provided on the side wall of the detection cavity. After the shell is inserted into the two sets of engaging grooves and pushed into the bottom, the first sealing head on the support plate will abut the wiring hole on the shell facing the detection cavity, and after the box cover closes the box opening, the second sealing head on the inner side of the box cover will abut the wiring hole on the shell facing the box opening. Therefore, the wiring holes on the shell will be blocked, so that the interior of the shell is in a closed state.
[0013] After the shell can be guaranteed to be in a closed state, pressurized water can be pumped into the shell to realize the detection of the shell. Therefore, the connecting plate is abutted against the bottom of the box, and the upper end opening of the water inlet pipe is abutted against the detection hole. A booster is arranged at the lower end of the water inlet pipe. Therefore, when the water flows into the booster, the water is pressurized by the booster and then pumped into the water inlet pipe. The pressurized water enters the inner cavity of the shell through the detection head, and pressure is applied to the shell. The detection head detects the information of the detection cavity. A heater can also be added between the connecting plate and the booster. By heating the pressurized water, the shell is subjected to high temperature while bearing water pressure, and the waterproof performance of the shell under high temperature and high pressure is tested. The booster and the heater are both controlled by the display controller.
[0014] Furthermore, it also includes a tube straightening assembly, which includes a guide column, a guide plate, a spring and a tube straightening head. The guide column is arranged on the support plate, and the guide hole on the guide plate cooperates with the guide column.

[0032] Description of the working method of this utility model:
[0033] In the transformer housing waterproof performance detection information collection device adopting the structure, the detection cavity 11 in the box body 1 forms a relatively closed space after being covered by the box cover 2. In order to detect the waterproof performance of the shell 3, a detection hole 12 penetrating the detection cavity 11 is opened at the bottom of the box body 1. The shell 3 is placed on the detection hole 12, and water is pumped into the shell 3 to detect the waterproof performance of the shell 3. A detection head 62 is provided at the top of the detection cavity 11, which can detect the humidity change in the detection cavity 11, the appearance change of the cover body, the air pressure change and other changes through humidity detection, camera detection, air pressure detection, etc., to detect whether the shell 3 is damaged due to The water mist spray caused by slight damage changes the air humidity in the detection cavity 11, or the damage on the outside of the shell 3 is obvious from the appearance, so it can be judged from the camera image, or a large amount of water is pressed into the detection cavity 11, causing the air in the detection cavity 11 to be compressed, thereby changing the air pressure in the detection cavity 11. Therefore, the detection head 62 can effectively detect and collect the environmental change information in the detection cavity 11, and then feed this information back to the display controller 61 for the operator to collect and store, so that a detection report can be issued for R&D personnel to modify the mold to improve the weak parts of the shell 3.
[0034] In order to ensure that the housing 3 can be pressed tightly against the detection hole 12, so as to prevent water from flowing out from the gap between the housing 3 and the detection chamber 11 when water is pumped in, thereby affecting the detection data, a fastening member 42 is provided, which is composed of two sets of engaging grooves 421 correspondingly and parallelly arranged at the bottom of the detection chamber 11, and the notches 422 on the two sets of engaging grooves 421 form a clamping portion, and the notches 422 are gradually enlarged toward the opening direction of the box body 1 when viewed from the side, and are gradually reduced near the opening of the box body 1. The structure is straight in the rear half of the slot 422, and the extensions 32 at the two end edges of the shell 3 cooperate with the snap-fitting parts. Therefore, when the shell 3 is inserted into the fastening member 42 from the snap-fitting parts, it is loose at first, which is convenient for the staff to pre-insert and guide the shell 3. After being pushed into the interior of the snap-fitting part, when it abuts against the rear half of the slot 422, the extensions 32 will be gradually pressed, so that the shell 3 is pressed tightly under the two sets of snap-fitting grooves 421, so that the shell 3 can be pressed tightly on the detection hole 12.
[0035] Since the shell 3 is provided with wiring holes 31 at the front and rear ends due to usage needs, the wiring holes 31 also need to be blocked to ensure that the internal space of the shell 3 is in a closed state. Therefore, a sealing component 41 is provided, and a support plate 411 is provided on the side wall of the detection chamber 11. After the shell 3 is inserted into the two sets of engaging grooves 421 and pushed into the bottom, the first blocking head 412 on the support plate 411 will abut against the wiring hole 31 on the shell 3 facing the detection chamber 11. After the box cover 2 closes the opening of the box body 1, the fixing column 21 is connected to the fixing groove 131 on the fixing seat 13 by rotation, so that the box cover 2 remains closed on the box body 1, and the second blocking head 413 on the inner side of the box cover 2 abuts against the wiring hole 31 on the shell 3 facing the opening of the box body 1. Therefore, the wiring holes 31 on the shell 3 are blocked, so that the interior of the shell 3 is in a closed state.
[0036] Since the shape of the lower end extension portion 32 of the shell 3 can be an irregular shape, when the shell 3 is inserted into the clamping portion, the wiring hole 31 on the shell 3 may not be exactly aligned with the first plugging head 412, so it is necessary to align the position of the shell 3, thereby providing a tube alignment component 7, and the guide column 71 is provided on the support plate 411 to play a role in guiding the direction, and the guide hole on the guide plate is fitted on the guide column 71, and the spring 73 is fitted on the guide column 71, and the front and rear of the spring 73 abut against the guide plate and the support plate 411, and the tube alignment head 74 at the lower end of the guide plate 72 abuts against the side surfaces of the extension portions 32 at both ends of the shell 3, so that when the shell 3 is pushed in, the extension The side of the extension part 32 abuts against the tube straightening head 74, pushing the tube straightening head 74 into the interior of the detection chamber 11, thereby compressing the spring 73 to produce deformation, and the supporting force generated by the spring 73 pushes the side of the extension part 32 in the opposite direction. It is optimal to set the side of the tube straightening head 74 to fit the shape of the side of the extension part 32, and at the same time, the tube straightening component 7 is set into two symmetrical groups, so that the two groups of tube straightening heads 74 can respectively abut against the side of the extension part 32 to push it for tube straightening. In order to ensure that the tube straightening head 74 can only move forward and backward within a limited range, a limit column 741 is provided on the lower end face of the tube straightening head 74, and the limit column 741 cooperates with the limit groove 111 on the bottom face of the detection chamber 11.
[0037] After the shell 3 is in a sealed state, pressurized water can be pumped into the shell 3 to realize the detection of the shell 3. Therefore, the connecting plate 51 is abutted against the bottom of the box body 1, and the upper end opening of the water inlet pipe 52 is abutted against the detection hole 12. In order to avoid water leakage at the connection between the connecting plate 51 and the bottom of the box body 1, a plurality of leak-proof grooves with the detection hole 12 as the rotation center can be provided on the bottom of the box body 1. A sealing ring is placed in the leak-proof groove. Therefore, in the process of the connecting plate 51 abutting against the bottom of the box body 1, the sealing ring can be used to play a waterproof role. A booster 53 is provided at the lower end of the water inlet pipe 52. Therefore, when the water flow enters the booster 53, the water is pressurized by the booster 53 and then pumped into the water inlet pipe 52, and the pressurized water enters the inner cavity of the shell 3 through the detection head 62. , pressure is applied to the shell 3, and the detection head 62 detects the information of the detection chamber 11; a heater 54 can also be added between the connecting plate 51 and the booster 53, and the pressurized water is heated so that the shell 3 is subjected to high temperature while bearing water pressure, and the waterproof performance of the shell 3 under high temperature and high pressure is tested. The booster 53 and the heater 54 are both controlled by the display controller 61. When the detection is completed, the water in the shell 3 needs to be discharged, and the booster 53 can be directly opened to discharge the water. The upper end of the detection hole 12 is set to an enlarged opening upward structure to avoid water accumulation in the shell 3; high-temperature and high-pressure air can also be introduced into the water inlet pipe 52, and the shell 3 is continuously pressurized by the air pressure, and information detection of weak parts of the shell 3 can also be performed.
[0038] The beneficial effect of the utility model is that the shell 3 is pressed against the detection hole 12 by the two sets of engaging grooves 421 on the fastening member 42, so as to prevent water from flowing out from the gap where the shell 3 and the detection cavity 11 abut when water is pumped in, thereby affecting the detection data; the first plugging head 412 and the second plugging head 413 on the sealing member 41 abut the wiring hole 31 on the shell 3 to ensure that the internal space of the shell 3 is in a closed state, and the high-temperature and high-pressure water is introduced from the bottom of the sealed shell 3, and the detection head 62 in the detection cavity 11 can effectively detect and collect the environmental change information in the detection cavity 11, thereby feeding back the information to the display controller 61 for the operator to collect and store, so that a detection report can be issued for the R&D personnel to modify the mold to improve the weak parts of the shell 3.
