By placing the metal rolling ball on a curved surface, when the metal ball rolls down due to vibration, the handheld terminal can receive an alarm message, which can be promptly alerted and checked.

Description

Technical Field

[0001] The invention belongs to the technical field of transformers, and in particular relates to a strong and stable transformer for indoor use. Background Art

[0002] The transformer needs to be fixed after installation, and relying on the transformer's own weight cannot achieve the effect of fixing the transformer. Due to the effect of electromagnetic force, the transformer will vibrate during operation, causing the transformer to move. And for transformers installed indoors, due to limited indoor space, they are usually not transported by large machinery. Therefore, indoor transformers are usually equipped with rollers, and transformers with rollers need to have the rollers firmly fixed. The current practice is to remove the rollers or fix them with angle irons in the form of a backrest. However, the method of removing the rollers is cumbersome and inconvenient to disassemble indoors with limited space. The angle iron backrest is the most convenient form, but it has poor safety and is easy to move, resulting in the inability to provide effective fixing. Summary of the Invention

[0018] The following description and accompanying drawings fully illustrate specific embodiments of the present invention to enable those skilled in the art to practice them. Other embodiments may include structural, logical, electrical, process and other changes. The examples represent only possible variations. Unless clearly required, separate components and functions are optional, and the order of operation may vary. Parts and features of some embodiments may be included in or replace parts and features of other embodiments.

[0019] In some illustrative embodiments, Figure 1-4As shown, a strong and stable transformer for indoor use comprises a transformer chassis 1 and a transformer body 2; the transformer body 2 is fixedly mounted on the transformer chassis 1 by welding. Moving feet are installed at the four corners of the transformer chassis 1 to facilitate the movement of the transformer.

[0020] The mobile foot includes a cylindrical tube 3, a threaded rod 4, a handle rod 5, and a metal ball 6. The cylindrical tube 3 has an internal thread that matches the threaded rod 4. The metal ball 6 is installed in the cylindrical tube 3, and the threaded rod 4 is assembled in the cylindrical tube 3, located above the metal ball 6. The end of the threaded rod 4 is provided with an arcuate surface 7 that matches the metal ball 6. A rubber column 8 is fixedly mounted at the head end of the threaded rod 4. A socket is provided in the shaft of the threaded rod 4, and the handle rod 5 is inserted into the socket. By rotating the handle rod 5, the threaded rod 4 can be screwed into or out of the cylindrical tube 3.

[0021] The device also includes a handheld terminal and an alarm 9; the handheld terminal is wirelessly connected to the alarm 9. The alarm 9 may include a single-chip microcomputer, a trigger button 10, and a wireless module, and the alarm 9 is wirelessly connected to the handheld terminal via the wireless module. When the trigger button 10 is pressed, the alarm enters a standby mode. When the trigger button 10 is reset, the single-chip microcomputer receives an electrical signal, which in turn transmits an alarm message to the handheld terminal via the wireless module. The handheld terminal may be a smart device such as a smartphone. The connection between the single-chip microcomputer, the trigger button, and the wireless module is conventional and need not be described in detail. The alarm 9's function of transmitting alarm messages can be implemented using existing single-chip microcomputers programmed using existing software, and need not be described in detail here. The alarm 9 is mounted within the threaded rod 4, with the trigger button of the alarm 9 located on the curved surface 7. The metal ball 6 compresses the trigger button 10, locking it in the locked position. When the metal ball 6 releases the curved surface 10, the trigger button 10 of the alarm 9 is reset, and the alarm 9 transmits the alarm message to the handheld terminal.

[0022] When using, Figure 1-2 As shown in Figures 3 and 4, the transformer chassis 2 is pushed and the metal ball 6 is rolled to move the transformer to the desired position. Use the handle 5 to unscrew the threaded rod 4 from the cylindrical tube 3. Remove the metal ball 6. Flip the threaded rod 4 so that the rubber column 8 faces downward. Place the rubber column 8 into the cylindrical tube 3 and screw the threaded rod 4 into the cylindrical tube 3 using the handle 5 until the rubber column 8 is firmly against the ground. The rubber column 8 increases friction with the ground and acts as a shock absorber. Place the removed metal ball 6 on the curved surface 7. The metal ball 6 presses the trigger button 10 of the alarm 9, putting the alarm 9 into standby mode. If the metal ball 6 falls off or detaches from the curved surface 7 due to vibration, movement, or other reasons, the trigger button 10 resets, the alarm 9 activates, and an alarm message is sent to the handheld terminal. After receiving the alarm message, maintenance personnel can promptly inspect and repair the device.

[0023] A level meter 11, a thermometer 12 and a hygrometer 13 are also installed on the transformer chassis for monitoring the indoor environment.

[0024] like Figure 4 As shown, in order to facilitate the removal of the metal ball 6, the cylindrical tube 3 includes a left half-cylinder 301 and a right half-cylinder 302. The left half-cylinder 301 and the right half-cylinder 302 are hinged at one end and fixedly connected at the other end by bolts. The left half-cylinder 301 and the right half-cylinder 302 can be opened by removing the bolts to facilitate the removal of the metal ball 6.

[0025] In an optional embodiment, it further includes a reserved bolt fixing hole 14; the reserved bolt fixing hole 14 is set on the transformer chassis 2, and the transformer chassis 2 can be fixed to the concrete through the reserved bolt fixing hole 14 by M16 bolts, thereby further fixing the transformer to prevent displacement.

[0026] In an optional embodiment, as Figure 2 、 3 As shown, to enhance the transformer's stability, a filling and weighing bin 15 is provided at the bottom of the transformer chassis 2. This bin 15 features a filling port for filling weights. The port can be positioned at different diameters and locations based on actual usage and the weights to be filled. The location and shape of the filling port are not specifically limited. The body 18 of the filling and weighing bin 15 defines a slot that fits within the bin bottom 17. The bin bottom 17 slides into the slot and secures it to the body 18. During use, after the transformer chassis 2 is moved to the desired position and secured, cement, sand, or water can be added through the filling port, or by placing a waterproof sheet inside the filling and weighing bin 15 for weighting. This further stabilizes the overall distribution system and reduces the impact of vibration and noise. When the unit needs to be moved again, the bin bottom 17 is removed from the slot in the body 18 to remove the filled weights.

[0027] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principles of the present invention should be considered as equivalent replacement methods and should be included in the scope of protection of the present invention.
