Description

Technical Field

[0001] The utility model relates to the technical field of generators, in particular to a waterproof and dustproof diesel generator set. Background Art

[0002] A generator set is a device that converts mechanical energy into electrical energy and is widely used in industrial, commercial, and household fields. It can not only provide a stable power supply but also serve as an emergency power source to ensure power demand in the event of a power outage, thus playing an important role in modern society and providing reliable power support.

[0003] Existing generator sets mainly include an engine, a generator, and a radiator attached to the engine. For example, the invention with the authorized publication number CN110318866B relates to a generator set, which includes a chassis and a first fan. The chassis is divided into a heat dissipation compartment and a power compartment. The power compartment is provided with an engine, a generator coaxially driven by the engine, and a wind guide cover with one end communicating with the heat dissipation compartment. The power compartment is provided with a first air inlet and a first air outlet, and the wind guide cover communicates with the first air outlet. During operation, the engine drives the generator to generate electricity, and the first fan blows air into the chassis, driving external air to enter the power compartment from the first air inlet, flowing through the generator and the engine and then reaching the heat dissipation compartment, and then flowing out from the wind guide cover to the first air outlet to dissipate heat.

[0004] However, when using the generator set in the prior art, in a sea platform or an island or a region with high humidity and large rainfall, water droplets are likely to flow into the chassis from the first air inlet and the first air outlet. The water droplets flowing into the chassis may corrode the circuit board and other devices, reducing the safety and service life of the power unit. Summary of the Utility Model

[0005] In order to improve the problem that water droplets in the prior art are likely to enter the chassis, thereby reducing the safety and service life of the generator set, the utility model provides a generator set with high sealing performance and good waterproof and dustproof effects.

[0006] A waterproof and dustproof diesel generator set provided by the utility model adopts the following technical scheme:

[0007] A waterproof and dustproof diesel generator set includes a frame, a casing arranged on the frame, a power unit arranged on the frame, a first window and a second window arranged on the casing. The air outlet end of the power unit faces the second window, and an air inlet hopper is arranged on the outer wall of the casing at the position of the first window;

[0008] One side of the air inlet hopper is the air inlet side, the air inlet side faces downward, and converging grooves are arranged on the side walls of the air inlet hopper close to the air inlet side, and a water outlet gap is formed between adjacent two converging grooves.

[0009] Through the above technical solution, during operation, the first window and the second window are driven to open. By driving the power unit, the generation and output of electric energy are realized. At the same time, the power unit drives the external air to enter the casing from the first window and flow through the power unit, so that the external air exchanges heat with the power unit. Finally, the gas follows the air flow and is discharged from the second window to the outside of the casing.

[0010] When it rains or there is water ingress, the rainwater drips onto the air intake hopper and the confluence trough. The water droplets on the air intake hopper flow into the confluence trough by gravity. The confluence trough converges the small water droplets into a water column and flows out from the water outlet gap. The weight of the water column is relatively large, so it cannot be sucked into the casing with the intake air, preventing water from entering the casing and protecting the equipment inside the casing. Therefore, it is applicable to offshore platforms, islands or areas with high humidity and large rainfall, improving the overall safety and the service life of the equipment.

[0011] Preferably, the casing is provided with a maintenance opening, and a maintenance door is covered on the maintenance opening. A sealing strip is wrapped around the edge of the maintenance door.

[0012] Through the above technical solution, the gap between the maintenance door and the maintenance opening is reduced by the sealing strip, improving the overall sealing performance, which is beneficial to preventing water droplets or dust from entering through the gap between the maintenance door and the maintenance opening.

[0013] Preferably, the power unit includes a base arranged on the frame, an engine and a generator arranged on the base. The engine is coaxially connected to the generator, and a radiator is arranged on one side of the engine.

[0014] Through the above technical solution, during operation, mechanical energy is generated by the engine and the generator is driven. At the same time, the radiator cools the engine, and the generation and output of electric energy can be realized.

[0015] Preferably, the side of the air intake hopper away from the air intake side is the guiding side, and the guiding side is inclined. The guiding side is used to guide the water droplets to flow into the confluence trough.

[0016] Through the above technical solution, when it rains or there is water ingress, due to the shielding of the air intake hopper, the water droplets cannot flow into the casing from the first window, and are guided by the guiding side to flow into the confluence trough.

[0017] Preferably, there are three first windows, and the three first windows are evenly distributed. The air intake hoppers are provided in three corresponding to the number of the first windows, and the three air intake hoppers are respectively located at the three first windows.

[0018] Through the above technical solution, through the three first windows, it is beneficial to increase the ventilation area, thereby improving the air intake efficiency and ensuring sufficient air intake.

[0019] Preferably, an exhaust seat is provided on the inner wall of the casing. The exhaust seat is located at the second window. A ventilation opening is formed in the exhaust seat and penetrates through the exhaust seat. The exhaust end of the radiator is in plug-in fit with the ventilation opening, and the exhaust end of the radiator is inserted into the ventilation opening.

[0020] Through the above technical solution, when the gas flowing through the generator and the engine is discharged from the exhaust end of the radiator to the ventilation opening and then discharged from the second window to the outside of the casing, and the exhaust end of the radiator is inserted into the ventilation opening, it is beneficial to more completely discharge the gas flowing through the generator and the engine, avoid the reflux of the high-temperature gas after heat exchange, and thus avoid affecting the heat dissipation effect.

[0021] Preferably, both the first window and the second window are electric louvers with high sealing performance.

[0022] Through the above technical solution, the use of electric louvers eliminates the need for manual adjustment, making the operation more convenient. Moreover, the high sealing performance can effectively block the penetration of water droplets or the entry of dust into the casing, achieving the effects of waterproofing and dustproofing. Combined with the sealing strip at the maintenance door, the overall sealing performance of the casing is good, resulting in a high dustproof level and a high waterproof level.

[0023] Preferably, the opening angles of both the first window and the second window are 70 - 85 degrees.

[0024] Through the above technical solution, since an opening angle greater than 90 degrees will cause the air flow to directly hit the blades, easily generating air flow disorder and eddy currents, increasing the resistance. However, an inclination angle of 70 - 85 degrees is beneficial for making the air flow more stable, reducing the air flow fluctuation, and lowering the air flow resistance, thus facilitating the smooth inflow of the air flow into the casing.

[0025] Compared with the prior art, the present utility model has the following beneficial effects:

[0026] Through the sealing strip on the maintenance door and the high sealing performance of the first window and the second window, the overall sealing performance of the casing is good, and the waterproof level and the dustproof level are high.

[0027] During operation, drive the first window and the second window to open. By driving the engine and the generator, the generation and output of electric energy are realized. The fan of the generator drives the external air to enter the casing from the first window, and after flowing through the generator, the engine, and reaching the radiator, the external air exchanges heat with the generator, the engine, and the radiator. Finally, the gas is discharged from the exhaust end of the radiator to the ventilation opening and then discharged from the second window to the outside of the casing.

[0028] When it rains or the device is submerged in water, rainwater drips onto the air intake funnel and the confluence trough. The water droplets on the air intake funnel fall into the confluence trough under the action of gravity and the guiding flow on the guiding side. The confluence trough converges the small water droplets into a water column, which flows out from the water outlet gap. The weight of the water column is relatively large, so it cannot be sucked into the casing along with the incoming air, preventing water from entering the casing and protecting the equipment inside the casing. It is applicable to offshore platforms, islands, or areas with high humidity and heavy rainfall, improving overall safety and the service life of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0038] The following will combine the attached drawings in the embodiments of the present invention [[ID=I4]] Figures 1 to 7, the technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0039] A waterproof and dustproof diesel generator set, referring to Figure 1 and Figure 2 , includes a rectangular frame 1, on which a cuboid-shaped casing 2 is installed, and the casing 2 is distributed along the length direction of the frame 1. A maintenance opening is provided on the long side of the casing 2, and a maintenance door 8 is covered on the maintenance opening. Referring to Figure 2 , the edge of the maintenance door 8 is wrapped with a sealing strip 9, so as to reduce the gap between the maintenance door 8 and the maintenance opening through the sealing strip 9, improve the overall sealing performance, and thus help prevent water droplets or dust from entering through the gap between the maintenance door 8 and the maintenance opening.

[0040] Referring to Figure 3 and Figure 4 , a power unit 3 for generating electric energy is provided on the frame 1. Specifically, the power unit 3 includes a base 31 provided on the frame 1, an engine 32 provided on the base 31, and a generator 33. The base 31 is rectangular and is distributed along the length direction of the frame 1. Among them, the engine 32 is a diesel engine, and both the engine 32 and the generator 33 are relatively mature technologies in the prior art and will not be elaborated here. The engine 32 and the generator 33 are coaxially connected, and the engine 32 and the generator 33 are distributed in sequence along the length direction of the base 31. A radiator 34 is provided on the side of the engine 32 facing away from the generator 33, and the radiator 34 is used to dissipate heat from the engine 32. In this embodiment, the radiator 34 is a water-cooled radiator 34. During operation, mechanical energy is generated by the engine 32 to drive the generator 33 to generate electricity. At the same time, the radiator 34 dissipates heat from the engine 32, thereby realizing the generation and output of electric energy.

[0041] Referring to Figure 5 and Figure 6 , a first window 4 is installed at one end of the casing 2, on the side of the first window 4 close to the generator 33. The first window 4 is rectangular and is distributed along the width direction of the casing 2. When the first window 4 is opened, the first window 4 connects the inside and outside of the casing 2. When the first window 4 is closed, the first window 4 isolates the inside and outside of the casing 2. In addition, the generator 33 includes a fan.

[0042] During operation, the first form 4 is driven to open. By driving the engine 32 and the generator 33, the generation and output of electric energy are achieved. The fan of the generator 33 drives external air to enter the housing 2 from the first form 4, and the external air flows through the generator 33, the engine 32 and then reaches the radiator 34, so that the external air exchanges heat with the heat on the generator 33, the engine 32 and the radiator 34, that is, the generator 33, the engine 32 and the radiator 34 are cooled.

[0043] In addition, continue to refer to Figure 5 With Figure 6 , there are three first forms 4, and the three first forms 4 are evenly distributed at equal intervals along the height direction of the housing 2. Therefore, through the three first forms 4, it is beneficial to increase the ventilation area, thereby improving the air intake efficiency and ensuring sufficient air intake.

[0044] Refer to Figure 5 With Figure 6 , a long strip-shaped air intake hopper 6 is provided on the housing 2. The air intake hopper 6 is distributed along the length direction of the first form 4, and the cross-section of the air intake hopper 6 is a right trapezoid. One side of the air intake hopper 6 located at the bottom of the right trapezoid is fixedly connected to the outer wall of the housing. There are three air intake hoppers 6 corresponding to the first form 4, and the three air intake hoppers 6 are respectively located at the three first forms 4. The side of the air intake hopper 6 located at the height of the right trapezoid is the air intake side 61, and the air intake side 61 is communicated with the side of the air intake hopper 6 located at the bottom, and the air intake side 61 faces downward.

[0045] In addition, continue to refer to Figure 5 With Figure 6 , a confluence groove 7 is also provided on the outer wall of the air intake hopper 6. The confluence groove 7 is long strip-shaped, and there are three confluence grooves 7. The three confluence grooves 7 are all close to the air intake side 61. The three confluence grooves 7 are respectively located on the three side walls of the air intake hopper 6, and there is a water outlet gap between two adjacent confluence grooves 7. Therefore, when it rains or there is water falling, the rainwater falls onto the air intake hopper 6 and the confluence groove 7. The water droplets on the air intake hopper 6 fall into the confluence groove 7 under the action of gravity and the guidance of the guiding side 62. The confluence groove 7 converges the small water droplets into a water column and flows out from the water outlet gap. The weight of the water column is relatively large, so it cannot be sucked into the housing 2 along with the air intake, preventing the housing 2 from being flooded and preventing damage to the equipment inside the housing 2, making it suitable for offshore platforms or islands or areas with high humidity and large rainfall.

[0046] Refer to Figure 6 , the side of the air intake hopper 6 located at the hypotenuse of the right trapezoid is the guiding side 62. The guiding side 62 is inclined downward from the side close to the housing 2 to the side away from the housing 2, and the guiding side 62 is used to guide the water droplets to flow into the confluence groove 7. Therefore, when it rains or there is water falling, due to the shielding of the air intake hopper 6, the water droplets cannot flow into the first form 4, and the water droplets flow into the confluence groove 7 under the guidance of the guiding side 62.

[0047] Refer toFigure 2 With Figure 7 , at one end of the housing 2 away from the first window 4, a second window 5 is provided. The second window 5 is rectangular and is distributed along the height direction of the housing 2. An exhaust seat 10 is provided on the inner wall of the housing 2. The exhaust seat 10 is located at the end where the second window 5 is located, and the exhaust seat 10 is square. A ventilation opening 11 is provided on the exhaust seat 10. The ventilation opening 11 is also square and is distributed along the length direction of the frame 1. The ventilation opening 11 penetrates through the exhaust seat 10. The exhaust end of the radiator 34 is in plug-in fit with the ventilation opening 11, and the exhaust end of the radiator 34 is inserted into the ventilation opening 11. When the second window 5 is opened, the second window 5 connects the outside of the housing 2 with the ventilation opening 11. When the second window 5 is closed, the second window 5 isolates the inside and outside of the housing 2. Thus, when the gas flowing through the generator 33 and the engine 32 is discharged from the exhaust end of the radiator 34 to the ventilation opening 11 and discharged from the second window 5 to the outside of the housing 2, by inserting the exhaust end of the radiator 34 into the ventilation opening 11, it is beneficial to more completely discharge the gas flowing through the generator 33 and the engine 32, avoid the backflow of the high-temperature gas after heat exchange, and thus avoid affecting the heat dissipation effect.

[0048] During operation, drive the first window 4 and the second window 5 to open. By driving the engine 32 and the generator 33, the generation and output of electric energy are realized. The fan of the generator 33 drives external air to enter the housing 2 from the first window 4 and flows through the generator 33, the engine 32 and then reaches the radiator 34, so that the external air exchanges heat with the generator 33, the engine 32 and the radiator 34, and finally is discharged from the exhaust end of the radiator 34 to the ventilation opening 11 and discharged from the second window 5 to the outside of the housing 2.

[0049] In this embodiment, referring to Figure 6 With Figure 7 , both the first window 4 and the second window 5 are electric shutters with high sealing performance. Using electric shutters eliminates the need for manual adjustment, making the operation more convenient. And the high sealing performance can effectively block the penetration of water droplets or the entry of dust into the housing 2, achieving a waterproof and dustproof effect. The opening angles of the first window 4 and the second window 5 are both 70 - 85 degrees, preferably 85 degrees. Since an opening angle greater than 90 degrees will cause the air flow to directly hit the blades, easily generating air flow disorder and eddy currents, increasing resistance, but an inclination angle of 70 - 85 degrees is beneficial to making the air flow more stable, reducing the fluctuation of the air flow, and reducing the resistance of the air flow, thus facilitating the smooth inflow of the air flow into the housing 2.

[0050] Through the sealing strip 9 at the maintenance door 8, the first window 4 and the second window 5, the overall sealing performance of the housing 2 is relatively good in the static state, so that the dustproof level and the waterproof level are relatively high. In this embodiment, the dustproof level reaches 5 and the waterproof level is 6, that is, it meets the IP56 standard.

[0051] The implementation principle of this application is as follows: Through the sealing strip 9 on the maintenance door 8, the first window 4, and the second window 5, the overall sealing performance of the casing 2 is relatively good in the static closed state, and the dustproof and waterproof levels are relatively high.

[0052] During operation, the first window 4 and the second window 5 are driven to open. By driving the engine 32 and the generator 33, the generation and output of electric energy are realized. The fan of the generator 33 drives external air to enter the casing 2 from the first window 4, and after flowing through the generator 33, the engine 32, it reaches the radiator 34, so that the external air exchanges heat with the generator 33, the engine 32, and the radiator 34. Finally, the gas is discharged from the exhaust end of the radiator 34 to the ventilation opening 11 and discharged from the second window 5 to the outside of the casing 2.

[0053] When it rains or there is water ingress, the rainwater drips onto the air inlet hopper 6 and the confluence trough 7. The water droplets on the air inlet hopper 6 fall into the confluence trough 7 under the action of gravity and the guidance of the guiding side 62. The confluence trough 7 converges the small water droplets into a water column and flows out through the water outlet gap. The weight of the water column is relatively large, so it cannot be sucked into the casing 2 along with the incoming air, preventing water from entering the casing 2 and preventing damage to the equipment inside the casing 2. It is applicable to offshore platforms, islands, or areas with high humidity and large rainfall, and improves the overall safety and the service life of the equipment.

[0054] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
