Description

Technical Field

[0001] This application relates to the field of generators, and more particularly to a silent diesel generator set with concealed hinges. Background Technology

[0002] Currently, a typical diesel generator set mainly consists of three parts: a diesel engine, a generator, and a control system. The diesel engine is responsible for fuel combustion and drives the generator rotor to rotate. The generator converts the power output from the diesel engine into alternating current with a certain voltage and frequency. The control system ensures the automatic start-up and safe operation of the generator set.

[0003] To reduce noise during operation, existing diesel generators typically have sound-absorbing cotton installed inside the casing. However, diesel generators also generate a lot of heat during operation, and the sound-absorbing cotton retains this heat, making it difficult to balance heat dissipation and noise reduction. Additionally, some connecting parts of existing generator sets protrude, which can cause them to touch the casing of adjacent generator sets during transportation, affecting the process. Utility Model Content

[0004] To address the difficulty of coexisting heat dissipation and noise reduction issues in diesel generators, this application provides a silent diesel generator set with a concealed hinge.

[0005] The concealed hinge silent diesel generator set provided in this application adopts the following technical solution: it includes an outer shell, with maintenance doors movably installed on both sides of the middle part of one side of the outer shell, sound-absorbing cotton provided on the inner wall of the outer shell, a generator body fixed on the inner wall of the outer shell, a heat absorption box provided on the outer wall of the generator body, an exhaust pipe fixed on the top of the generator body, a water inlet pipe and a water outlet pipe that are sealed and connected through one side of the heat absorption box, a water storage tank fixed on the outer wall of the outer shell, the water storage tank being sealed and connected through the water inlet pipe and the water outlet pipe, a servo motor fixed on the top of the water storage tank by a second support block, a fan duct fixed to the power output end of the servo motor, and heat-conducting fins fixed through the top of the water storage tank.

[0006] By adopting the above technical solution, the sound-absorbing cotton absorbs the noise inside the outer shell, the heat absorption box absorbs the heat generated by the generator body, and a water pump is fixed inside the water storage tank near the water inlet pipe to circulate the water inside the water storage tank and the heat absorption box.

[0007] Preferably, multiple heat-conducting fins are provided, and the multiple heat-conducting fins are arranged horizontally and vertically at equal intervals, and the heat-conducting fins are arranged at an angle to the air duct.

[0008] By adopting the above technical solution, the water inside the water tank absorbs heat through multiple heat-conducting fins. The inclined heat-conducting fins can better receive the wind force generated by the rotation of the fan duct, thereby improving the heat dissipation efficiency.

[0009] Preferably, a first support block is fixed at the other end of the top of the water storage tank, and the first support block is rotatably connected to the other end of the air duct, and the air duct is used in conjunction with multiple heat-conducting fins.

[0010] By adopting the above technical solution, the servo motor drives the air duct to rotate, generating wind to cool the top of the heat-conducting fins. The temperature of the heat-conducting fins outside the water storage tank is the same as the temperature inside the water storage tank, so the heat-conducting fins can cool the water inside the water storage tank.

[0011] Preferably, the exhaust pipe passes through the heat absorption box and the sound-absorbing cotton, and heat insulation cotton is provided at the connection between the exhaust pipe and the sound-absorbing cotton.

[0012] By adopting the above technical solution, the exhaust pipe is used to discharge the hot exhaust gas generated when the generator is working to the outside, and heat insulation cotton is installed to avoid damage to the sound-absorbing cotton.

[0013] Preferably, the inner wall of the exhaust pipe is threaded with a threaded tube, and a rain cover is fixed to the top of the threaded tube. The rain cover is hollow on all four sides.

[0014] By adopting the above technical solution, the top of the threaded tube is covered by a rain cover to protect it from rain, without affecting the exhaust of the exhaust pipe and the threaded tube. During transportation, the threaded tube can be rotated to put the threaded tube and the rain cover into the exhaust pipe, so that multiple outer shells can be stacked.

[0015] Preferably, both ends of the two inspection doors on opposite sides are fixed with concealed hinge bodies, and the other end of the four concealed hinge bodies is fixed to one side of the inner wall of the outer shell.

[0016] By adopting the above technical solution, and by setting a concealed hinge inside the outer shell, the hinge is not visible on the external surface, making the unit look beautiful, elegant and simple. The portion protruding from the outer box is reduced, and the outer shells can fit tightly together, which is convenient for packaging and transportation.

[0017] Preferably, the sound-absorbing cotton fills the inner wall of the outer shell and the two inspection doors on the side near the inner wall of the outer shell, and the sound-absorbing cotton at the gap between the inspection doors and the outer shell is cut.

[0018] By adopting the above technical solution, the inspection door and the inside of the outer casing are fully covered with sound-absorbing cotton, maximizing sound absorption and reducing the noise generated by the generator body during operation.

[0019] In summary, this application includes at least the following beneficial technical effects:

[0020] 1. This application starts a servo motor to drive the air duct to rotate, generating wind to cool the top of the heat-conducting fins. The heat-conducting fins cool the water inside the water tank. Multiple heat-conducting fins absorb heat from the water inside the water tank. The inclined heat-conducting fins can better receive the wind generated by the rotation of the air duct, improving heat dissipation efficiency. The sound-absorbing cotton fully covers the inspection door and the inside of the outer shell, maximizing sound absorption and reducing the noise generated when the generator is working. Thus, it achieves the effect of having good sound insulation while also effectively dissipating heat.

[0021] 2. This application installs the access door with concealed hinges, thereby making the hinges invisible on the external surface. This makes the unit look beautiful, simple, and elegant. It reduces the protruding part of the outer casing, allows the outer casing to fit tightly together, facilitates packaging and transportation, and avoids the effect of hinge damage that may occur when multiple units are adjacent during container transportation.

[0027] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0028] This application discloses a concealed hinge silent diesel generator set, including an outer shell 1. Inspection doors 14 are movably installed on both sides of the middle section of one side of the outer shell 1. Sound-absorbing cotton 2 is provided on the inner wall of the outer shell 1 to absorb noise from inside the outer shell 1. A generator body 3 is fixed to the inner wall of the outer shell 1. A heat absorption box 4 is provided on the outer wall of the generator body 3 to absorb the heat generated by the generator body 3. An exhaust pipe 11 is fixed to the top of the generator body 3. An inlet pipe 5 and an outlet pipe 6 are sealed and connected through one side of the heat absorption box 4. A water storage tank 7 is fixed to the outer wall of the outer shell 1, and the water storage tank 7 is sealed and connected through the inlet pipe 5 and the outlet pipe 6. A water pump is fixed inside the water storage tank 7 near the inlet pipe 5, circulating water between the water storage tank 7 and the heat absorption box 4. A servo motor 9 is fixed to the top of the water storage tank 7 via a second support block 17. A fan duct 10 is fixed to the power output end of the servo motor 9. A heat-conducting fin 8 is fixed through the top of the water storage tank 7.

[0029] Reference Appendix Figure 1 and 2 The heat-conducting fins 8 are provided in multiple ways, and are arranged horizontally and vertically at equal intervals. The heat-conducting fins 8 are also inclined to the air duct 10. The water inside the water storage tank 7 is heated by the multiple heat-conducting fins 8. The inclined heat-conducting fins 8 can better receive the wind force generated by the rotation of the air duct 10, thereby improving the heat dissipation efficiency.

[0030] Reference Appendix Figure 1 and 2 The water storage tank 7 has a first support block 16 fixed at one end of its top. The first support block 16 is rotatably connected to the other end of the air duct 10. The air duct 10 is used in conjunction with multiple heat-conducting fins 8. The air duct 10 is driven to rotate by a servo motor 9, which generates wind to cool the top of the heat-conducting fins 8. The temperature of the heat-conducting fins 8 outside the water storage tank 7 is the same as the temperature inside the water storage tank 7. The heat-conducting fins 8 can cool the water inside the water storage tank 7.

[0031] Reference Appendix Figure 3 The exhaust pipe 11 is connected to the heat absorption box 4 and the sound absorption cotton 2. The connection between the exhaust pipe 11 and the sound absorption cotton 2 is provided with heat insulation cotton. The exhaust pipe 11 is used to discharge the hot exhaust gas generated by the generator body 3 to the outside. The sound absorption cotton 2 is protected from damage by the heat insulation cotton.

[0032] Reference Appendix Figure 3The inner wall of the exhaust pipe 11 is threaded with a threaded pipe 12, and a rain cover 13 is fixed to the top of the threaded pipe 12. The rain cover 13 is hollow on all sides and can cover the top of the threaded pipe 12 to keep it dry without affecting the exhaust of the exhaust pipe 11 and the threaded pipe 12. During transportation, the threaded pipe 12 can be rotated to put the threaded pipe 12 and the rain cover 13 into the exhaust pipe 11, so that multiple outer shells 1 can be stacked.

[0033] Reference Appendix Figure 4 Two of the two inspection doors 14 are fixed with concealed hinge bodies 15 at both ends on opposite sides. The other end of the four concealed hinge bodies 15 is fixed to one side of the inner wall of the outer shell 1. By setting concealed hinge bodies 15 inside the outer shell 1, the hinges are not visible on the outer surface, making the unit look beautiful, elegant and simple. The part protruding from the outer box is reduced, and the outer shells can fit tightly together, which is convenient for packaging and transportation.

[0034] Reference Appendix Figure 4 The sound-absorbing cotton 2 fills the inner wall of the outer shell 1 and the two inspection doors 14 near the inner wall of the outer shell 1. The sound-absorbing cotton 2 at the gap between the inspection door 14 and the outer shell 1 is cut. By using the sound-absorbing cotton 2 to fully cover the inspection door 14 and the inside of the outer shell 1, the sound absorption is maximized to reduce the noise generated when the generator body 3 is working.

[0035] The implementation principle of the concealed hinge silent diesel generator set in this application embodiment is as follows: First, during transportation, the threaded pipe 12 can be rotated to retract the threaded pipe 12 and the rain cover 13 into the exhaust pipe 11, allowing multiple outer shells 1 to be stacked. By setting a concealed hinge 15 inside the outer shell 1, the hinge is not visible on the external surface, making the unit look beautiful, simple, and elegant. The portion protruding from the outer casing is reduced, and the outer shells can fit tightly together, facilitating packaging and transportation. When in use, the threaded pipe 12 is rotated out, and the generator 3 is started to operate. The exhaust pipe 11 is used to discharge the hot exhaust gas generated by the generator 3 to the outside. By installing heat insulation cotton to avoid damaging the sound-absorbing cotton 2, the servo motor 9 is started to drive the air duct 10 to rotate, generating wind to cool the top of the heat-conducting fins 8. The temperature of the heat-conducting fins 8 outside the water storage tank 7 is the same as the temperature inside the water storage tank 7, so the heat-conducting fins 8 can cool the water inside the water storage tank 7. The water inside the water storage tank 7 is absorbed by multiple heat-conducting fins 8. The inclined heat-conducting fins 8 can better receive the wind generated by the rotation of the air duct 10, improving the heat dissipation efficiency. The sound-absorbing cotton 2 fully covers the inspection door 14 and the inside of the outer shell 1, maximizing sound absorption and reducing the noise generated by the generator body 3 when it is working.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
