[0002] A transformer is a static electrical device used to transform AC voltage and current and transmit AC electrical energy. It realizes the transmission of electrical energy based on the principle of electromagnetic induction. Transformers can be classified into power transformers, test transformers, instrument transformers, and transformers for special purposes according to their uses: Power transformers are necessary equipment for power transmission and distribution and power user distribution; Test transformers are equipment for performing withstand voltage (boosting voltage) tests on electrical equipment; Instrument transformers are used for electrical measurement and relay protection in the power distribution system (PT, CT); Transformers for special purposes include electric furnace transformers for smelting, welding transformers, rectifier transformers for electrolysis, small voltage regulating transformers, etc.

[0003] In the existing transformer box, generally, the coil needs to be fixed on the fixing frame arranged inside the box to ensure the stability of the coil inside the box and prevent it from tipping over. However, the narrow space inside the transformer box during the installation process affects the operation of the construction personnel. Not only is the installation efficiency low, but also the insulation layer of the coil is easily damaged during the operation. After the coil is completely installed, the protection ability for the coil is insufficient, which cannot meet the actual use requirements. Therefore, a transformer box with convenient installation is proposed to solve the above problems. Summary of the Invention

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention;

[0034] Please refer to Figures 1-6 , in the present invention, a transformer box body with convenient installation includes a box body shell 1. Guide rails 2 are fixedly connected to the front and back sides inside the box body shell 1. A coil mounting frame 3 is slidably connected between the two guide rails 2. A shock absorption mechanism 4 is fixedly installed on the inner bottom wall of the box body shell 1. A guiding and limiting mechanism 5 is installed on the shock absorption mechanism 4. The tops of the shock absorption mechanism 4 and the guiding and limiting mechanism 5 are both connected to the coil mounting frame 3;

[0035] The guide rail 2 includes a sliding guide rail 21. Three guiding guide rails 22 are integrally formed at the bottom of the sliding guide rail 21. Three support sliders 31 are welded to the front and back sides of the coil mounting frame 3. The six support sliders 31 respectively extend into the six guiding guide rails 22 and are in smooth contact with the inner walls of the guiding guide rails 22.

[0036] In the present invention, the shock absorption mechanism 4 and the guiding and limiting mechanism 5 cooperate to move the coil mounting frame 3 upward, so that the support sliders 31 slide from the inside of the guiding guide rails 22 into the inside of the sliding guide rail 21, thereby facilitating the extraction of the coil mounting frame 3 from the inside of the box body shell 1, so as to facilitate the installation and fixation of the coil structure of the transformer on the coil mounting frame 3, avoiding installation work inside the narrow box body shell 1, giving sufficient operating space to the construction personnel, thereby improving the installation efficiency and effect, reducing the probability of damage to the coil of the transformer during installation. After the installation is completed, the coil mounting frame 3 is pushed into the inside of the box body shell 1 along the guide rail 2. When the six support sliders 31 respectively move above the corresponding six guiding guide rails 22, they fall through the guiding guide rails 22 and enter the inside of the guiding guide rails 22. At the same time, the coil mounting frame 3 contacts the shock absorption mechanism 4, and the shock absorption mechanism 4 provides support and gives a shock absorption function, so as to provide shock absorption and protection for the coil inside the transformer box body in scenarios such as transportation, installation, and use. The use safety is higher and the practicability is stronger, meeting the market use requirements.

[0037] Please refer to Figure 2 And Figure 6 , wherein: the shock absorption mechanism 4 includes a plurality of telescopic rods 41. A shock absorption spring 42 is sleeved on the telescopic rod 41. The top of the telescopic rod 41 is fixedly connected to a support plate 43. The top of the shock absorption spring 42 is fixedly connected to the support plate 43. The guiding and limiting mechanism 5 is installed on the support plate 43.

[0038] In the present invention, the telescopic rod 41 is used to connect the support plate 43 to the inner wall of the box body shell 1, and at the same time gives a certain lifting space to the support plate 43, and the upward elastic force is provided by the shock absorption spring 42 to achieve a shock absorption and buffering effect.

[0039] See also Figure 2 and Figure 5 , wherein: the guide and limiting mechanism 5 includes a mounting block 51, a servo motor 52 is fixedly mounted on the mounting block 51, a transmission worm 53 is fixedly connected to the output shaft of the servo motor 52, and a transmission rack 54 is fixedly mounted on the bottom of the inner side of the coil mounting frame 3, and the transmission rack 54 is meshed with the transmission worm 53.

[0040] In the present invention, the mounting block 51 provides a support and fixing point for the servo motor 52. When the transmission worm 53 is in contact and meshing with the transmission rack 54, the left and right movement of the coil mounting frame 3 can be limited. At the same time, a guiding force can be provided for the upward movement of the coil mounting frame 3 from the guide rail 22 into the guide rail 22, so as to facilitate the extraction of the coil mounting frame 3 and the installation and replacement of the transformer coil.

[0041] See also Figure 2 and Figure 6 , wherein: the telescopic rod 41 includes a storage tube 411, a piston 412 is slidably connected to the inner side of the storage tube 411, an extension rod 413 is fixedly connected to the top of the piston 412, the top of the extension rod 413 is fixedly connected to the support plate 43, and a first ventilation pipe 414 connected to the storage tube 411 is fixedly connected.

[0042] In the present invention, when the first ventilation pipe 414 is connected to an external air pump, the interior of the storage tube 411 can be inflated and pressurized, thereby driving the storage tube 411 on the piston 412 to rise and fall, so as to facilitate the coil mounting frame 3 to be supported, and at the same time facilitate the coil mounting frame 3 to rise, thereby facilitating the extraction of the coil mounting frame 3.

[0043] See also Figure 2 and Figure 5 , wherein: the mounting block 51 includes a movable box 512, a lifting plate 513 is arranged on the inner side of the movable box 512, a sealing ring 511 is fixedly connected to the lifting plate 513, the outer side of the sealing ring 511 is slidably connected to the inner wall of the movable box 512, the servo motor 52 is fixedly mounted on the lifting plate 513, and a second ventilation pipe 514 connected to the movable box 512 is fixedly connected.

[0044] In the present invention, when the second ventilation pipe 514 is connected to the external air pump, it is convenient to inflate and pressurize the interior of the movable box 512. Due to the restriction of the sealing ring 511, the lifting plate 513 rises under the action of air pressure, thereby driving the servo motor 52 on the lifting plate 513 to rise and fall, controlling the engagement and disengagement of the transmission rack 54 and the transmission worm 53. When the movable box 512 is deflated, the transmission worm 53 descends to avoid affecting the push-pull process of the coil mounting frame 3. The structure is novel, scientific, reasonable and reliable.

[0045] Please refer to Figure 1 、 2 、 5 and 6, wherein: an inflation pipe 6 is inserted through the box body shell 1, and both the first ventilation pipe 414 and the second ventilation pipe 514 are integrally formed and communicated with the inflation pipe 6.

[0046] In the present invention, the first ventilation pipe 414 and the second ventilation pipe 514 are conveniently connected to an external air pump device through the inflation pipe 6, so as to facilitate the inflation and deflation operations, and the operation is simple and convenient.

[0047] Please refer to Figures 1-4 , wherein: reinforcing blocks 7 are fixedly connected to the bottom of the guide rail 2 at equal intervals, and one side of the reinforcing block 7 is fixedly connected to the inner wall of the box body shell 1.

[0048] In the present invention, the connection structure between the guide rail 2 and the box body shell 1 is strengthened through the reinforcing block 7 to ensure the structural stability of the guide rail 2.

[0049] Please refer to Figure 2 、 5 and 6, wherein: control valves 8 are fixedly installed on both the first ventilation pipe 414 and the second ventilation pipe 514.

[0050] In the present invention, the opening and closing of the first ventilation pipe 414 and the second ventilation pipe 514 are controlled through the control valve 8, which facilitates the control and use by construction workers.

[0051] Working principle: The coil mounting bracket 3 is lifted by the cooperation of the shock absorption mechanism 4 and the guiding and restricting mechanism 5, so that the supporting slider 31 slides into the inner side of the sliding guide rail 21 from the guiding guide rail 22, thereby facilitating the extraction of the coil mounting bracket 3 from the inside of the box body shell 1, so as to facilitate the installation and fixation of the coil structure of the transformer on the coil mounting bracket 3, avoiding installation work inside the narrow box body shell 1, giving construction workers enough operating space, thereby improving the installation efficiency and effect, reducing the probability of damage to the transformer coil during installation. After the installation is completed, the coil mounting bracket 3 is pushed into the inside of the box body shell 1 along the guide rail 2. When the six supporting sliders 31 respectively move above the corresponding six guiding guide rails 22, they fall through the guiding guide rail 22 and enter the inside of the guiding guide rail 22. At the same time, the coil mounting bracket 3 contacts the shock absorption mechanism 4, and the shock absorption mechanism 4 provides support and gives a shock absorption function, so as to provide shock absorption and protection for the coil inside the transformer box body in scenarios such as transportation, installation, and use. The use safety is higher, the practicability is stronger, and it meets the market use requirements.
