An accommodating cavity is formed inside the prefabricated power cabin body. Buffer cavities are formed on both sides of the prefabricated power cabin body, and anti-collision strips are installed inside the buffer cavities. A heat dissipation component to assist airflow is installed on both sides of the prefabricated power cabin body above the buffer cavities. A sealing cavity is formed at one end of the prefabricated power cabin body, and a sealing component is installed inside the sealing cavity. A sealing groove is formed at the other end of the prefabricated power cabin body, and the sealing component and the sealing groove cooperate to form a seal.

[0007] Optionally, the heat dissipation assembly includes a heat dissipation shroud installed on the main body of the prefabricated power pod, an air guide channel is provided inside the heat dissipation shroud, a baffle net is fixed inside the air guide channel, an air guide pipe is fixed on the inner side of the receiving cavity of the main body of the prefabricated power pod, the air guide pipe is connected to the heat dissipation shroud, and an air guide hole is provided on the air guide pipe.

[0008] Optionally, a cross-shaped mounting bracket is fixed inside the air duct of the heat sink, a servo motor is rotatably mounted on the mounting bracket, and a guide fan that drives the servo motor to rotate is mounted on the mounting bracket.

[0009] Optionally, a plurality of anti-collision strips are provided, and the plurality of anti-collision strips are equidistantly arranged within the buffer cavity.

[0010] Optionally, the cross-section of the anti-collision strip is trapezoidal, and an energy-absorbing cavity is formed between the buffer cavity and the anti-collision strip.

[0011] Optionally, the sealing assembly includes a guide rod vertically fixed in the sealing cavity, a sealing strip slidably disposed on the guide rod, the sealing strip and the sealing groove being sealed together, and an ejector spring for assisting the sealing strip to be pushed on the guide rod.

[0012] An installation and fixing structure for a prefabricated power module includes a tensioning pin and a tensioning assembly for connecting the two ends of the prefabricated power module body. The prefabricated power module body has a sliding cavity for installing the tensioning assembly and a fixing groove for inserting the tensioning assembly. The tensioning pin is laterally inserted into the fixing groove.

[0013] Optionally, the tensioning assembly includes a push plate slidably disposed in a sliding cavity, a hook fixed on one side of the push plate, the hook extending out of the sliding cavity, a lead screw rotatably disposed in the sliding cavity, the push plate being sleeved on the lead screw, the push plate and the lead screw being threadedly engaged, and a knob for adjusting the lead screw rotation is installed on the main body of the prefabricated power cabin.

[0014] Optionally, a worm gear is fixed on one side of the knob, and a worm wheel is fixed at the end of the lead screw facing the worm gear, with the worm wheel and the worm gear engaging in transmission.

The push plate and the lead screw are threaded together, so that the push plate moves, and the hook moves, so that the hook is snapped onto the tensioning pin and the hook and the tensioning pin are locked together. This allows the two precast power pod bodies to be locked together and connected. During operation, the connection between the two precast power pod bodies can be easily and quickly achieved. When the precast power pod bodies need to be disassembled later, the tensioning pin can be removed to achieve the overall disassembly of the two precast power pod bodies.

[0018] By setting up heat dissipation components, the guide fan is activated, which drives the servo motor to rotate as a whole. The servo motor drives the airflow inside the air duct, and when the airflow inside the air duct flows, the airflow inside the power prefabricated compartment is drawn out through the air duct holes, thereby providing auxiliary heat dissipation for the inside of the power prefabricated compartment and avoiding problems such as ineffective heat dissipation when the internal temperature of the power prefabricated compartment is high.

[0019] By using a sealing assembly, during the mutual tightening of the two precast power modules, a spring is ejected and snapped into the sealing groove, thereby achieving a tight seal between the two precast power modules. This improves the overall sealing performance at the connection between the two precast power modules and ensures smooth operation of subsequent work. Attached Figure Description

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of this utility model provides a prefabricated power cabin, including a prefabricated power cabin body 1. Each of the four corners of the bottom of the prefabricated power cabin body 1 has a protruding seat 2. A cabin roof 3 protrudes from the top of the prefabricated power cabin body 1, and drainage grooves 4 are equidistantly arranged on the cabin roof 3. An accommodating cavity is formed inside the prefabricated power cabin body 1. Buffer cavities are formed on both sides of the prefabricated power cabin body 1. Anti-collision strips 13 are installed inside the buffer cavities. Several anti-collision strips 13 are arranged equidistantly within the buffer cavities. The cross-section of each anti-collision strip 13 is trapezoidal. An energy-absorbing cavity is formed between the buffer cavities and the anti-collision strips 13. Through the anti-collision strips 13, a good anti-collision effect can be achieved when the prefabricated power cabin body 1 encounters an external impact during operation.

[0035] On both sides of the prefabricated power cabin body 1, above the buffer chamber, heat dissipation components 14 for auxiliary airflow are installed. The heat dissipation components 14 include a heat dissipation shroud 15 installed on the prefabricated power cabin body 1. A cross-shaped mounting bracket is fixed in the air guide channel of the heat dissipation shroud 15. A servo motor 16 is rotatably mounted on the mounting bracket. A guide fan 161 that drives the servo motor 16 to rotate is mounted on the mounting bracket. An air guide channel is opened inside the heat dissipation shroud 15. A baffle net 151 is fixed in the air guide channel. An air guide pipe 17 is fixed on the inner side of the receiving cavity of the prefabricated power cabin body 1. The air guide pipe 17 is connected to the heat dissipation shroud 15. An air guide hole 171 is opened on the air guide pipe 17.

[0036] By using the heat dissipation component 14, the guide fan 161 is activated. The guide fan 161 drives the servo motor 16 to rotate as a whole. The servo motor 16 drives the airflow inside the air duct 17. When the airflow inside the air duct 17 flows, the airflow inside the cavity of the prefabricated power module 1 is extracted through the air duct 171, thereby providing auxiliary heat dissipation for the inside of the prefabricated power module 1. This can minimize the problem of ineffective heat dissipation when the internal temperature of the prefabricated power module 1 is high.

[0037] One end of the prefabricated power module body 1 is provided with a sealing cavity, and a sealing component 18 is installed in the sealing cavity. The other end of the prefabricated power module body 1 is provided with a sealing groove. The sealing component 18 and the sealing groove cooperate to seal. The sealing component 18 includes a guide rod 19 vertically fixed in the sealing cavity. A sealing strip 21 is slidably provided on the guide rod 19. The sealing strip 21 cooperates to seal with the sealing groove. An ejector spring 20 is sleeved on the guide rod 19 to push the auxiliary sealing strip 21.

[0038] With the sealing component 18 in place, during the mutual tightening of the two prefabricated power modules 1, the ejector spring 20 is snapped into the sealing groove, thereby achieving a sealing treatment between the two prefabricated power modules 1. This improves the overall sealing at the connection between the two prefabricated power modules 1 and ensures the smooth progress of subsequent work.

[0039] like Figure 1 , Figure 4 and Figure 5 As shown, an embodiment of this utility model provides an installation and fixing structure for a prefabricated power module, including a tensioning pin 6 and a tensioning assembly 7 for connecting the two ends of the prefabricated power module body 1. The prefabricated power module body 1 has a sliding cavity for installing the tensioning assembly 7, and a fixing groove 5 for inserting the tensioning assembly 7. The tensioning pin 6 is laterally inserted into the fixing groove 5. The tensioning assembly 7 includes a push plate 8 slidably disposed in the sliding cavity, and a hook 9 is fixed on one side of the push plate 8. 9. The slide cavity extends outward, and a lead screw 10 is rotatably installed inside the slide cavity. A push plate 8 is sleeved and installed on the lead screw 10. The push plate 8 and the lead screw 10 are threadedly engaged. A knob 121 is installed on the main body 1 of the power prefabricated cabin to drive the lead screw 10 to rotate and adjust. A worm gear 12 is fixed on one side of the knob 121. A worm wheel 11 is fixed at one end of the lead screw 10 facing the worm gear 12. The worm wheel 11 and the worm gear 12 are engaged for transmission. The fixing groove 5 is threadedly engaged with the tension pin 6. One end of the tension pin 6 extends out of the tension pin 6.

[0040] By using the fixing groove 5 at one end of the precast power module body 1, and the cooperation between the tensioning pin 6 and the tensioning assembly 7, the two ends of the precast power module body 1 are brought together. The hook 9 on the tensioning assembly 7 is inserted into the fixing groove 5, and the tensioning pin 6 is inserted into the fixing groove 5. The precast power module body 1 and the tensioning pin 6 are threaded together, thus fixing the tensioning pin 6 laterally in the fixing groove 5. Rotating the knob 121 causes the worm gear 12 to rotate as a whole. The worm gear 12 is threaded together with the worm wheel 11, thus causing the worm wheel 11 to rotate clockwise. The worm wheel 11 drives the wire... The rod 10 rotates as a whole, pushing the threaded engagement between the push plate 8 and the lead screw 10, thereby moving the push plate 8 as a whole, which in turn moves the hook 9 as a whole, so that the hook 9 is snapped onto the tension pin 6, and the hook 9 and the tension pin 6 are locked together, so that the two prefabricated power pod bodies 1 can be locked together and connected and fastened. This allows for convenient and quick connection and fastening of the two prefabricated power pod bodies 1 during operation, and when it is necessary to disassemble the prefabricated power pod bodies 1 in the future, the tension pin 6 can be directly removed to achieve the overall disassembly of the two prefabricated power pod bodies 1.

[0041] The working principle of the technical solution provided by this utility model is as follows:

[0042] When the prefabricated power module body 1 needs to be installed, the two ends of the prefabricated power module body 1 are fitted together, and the hook 9 on the tensioning assembly 7 is inserted into the fixing groove 5. The tensioning pin 6 is inserted into the fixing groove 5, and the prefabricated power module body 1 and the tensioning pin 6 are threaded together, so that the tensioning pin 6 is horizontally fixed in the fixing groove 5. Rotate the knob 121, and the knob 121 drives the worm gear 12 to rotate as a whole. The worm gear 12 and the worm wheel 11 are threaded together, so that the worm wheel 11 rotates in the forward direction. The worm wheel 11 drives the lead screw 10 to rotate as a whole. The push plate 8 and the lead screw 10 are threaded together, so that the push plate 8 moves as a whole, and then the hook 9 moves as a whole, so that the hook 9 is snapped onto the tensioning pin 6, and the hook 9 and the tensioning pin 6 are locked together, so that the two prefabricated power module bodies 1 can be locked together and connected and tightened. During the mutual tightening process of the two prefabricated power module bodies 1, the ejector spring 20 is snapped into the sealing groove, so as to achieve the sealing treatment between the two prefabricated power module bodies 1.

[0043] During ventilation, the guide fan 161 is activated, which drives the servo motor 16 to rotate as a whole. The servo motor 16 drives the airflow inside the air duct 17, and when the airflow inside the air duct 17 flows, the airflow inside the power prefabricated cabin body 1 is extracted through the air duct hole 171, thereby providing auxiliary heat dissipation treatment inside the power prefabricated cabin body 1.

To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0045] The above description is only a preferred embodiment of the present utility model.
