Description

Technical Field

[0001] The present invention relates to the technical field of generators, and particularly to a structure of a wind guide cover for a generator set. Background Art

[0002] At present, there are mainly two ways to dissipate heat from the inverter on the generator set. One is to directly dissipate heat by using a radiator, and the other is to dissipate heat through the cooling air duct of the generator set. For the existing wind guide cover structure, the air supply effect to the inverter is limited, resulting in poor heat dissipation function of the inverter. Especially for low-voltage inverters, the heat generation of low-voltage inverters is higher than that of general inverters, and the wind guide cover structure cannot meet the air supply requirements, making the inverter unable to effectively dissipate heat.

[0003] The prior art CN220554251U provides a wind guide cover for a generator set. By arranging a plurality of longitudinal wind guide vanes from left to right near the air guide opening in the air guide channel, it plays a guiding role and effectively increases the air volume of the air guide opening. Specifically, when the longitudinal wind guide vanes are not arranged, the cooling air is easily introduced into the air guide channel from the rightmost end of the air guide opening. After adding the longitudinal wind guide vanes, the air guide opening is divided into multiple air inlet gaps, and each gap has a wind guiding effect. The actual air inlet of the air guide opening is horizontally widened, so that more cooling air enters the air guide channel.

[0004] However, in the prior art, relatively large noise is easily generated during the air inlet process of the wind guide cover, and noise pollution is easily emitted to the surrounding area during the operation of the generator set. Summary of the Invention

[0005] An object of the present invention is to provide a structure of a wind guide cover for a generator set, aiming to solve the technical problem that relatively large noise is easily generated during the air inlet process of the wind guide cover in the prior art, and noise pollution is easily emitted to the surrounding area during the operation of the generator set.

[0006] To achieve the above object, a structure of a wind guide cover for a generator set adopted by the present invention includes a wind guide cover main body and further includes a noise reduction mechanism. The noise reduction mechanism includes a noise reduction cylinder body, a guide vane, a filter screen, a screen frame and a limit block. The noise reduction cylinder body is connected to the wind guide cover main body through bolts and is located at one end of the wind guide cover main body. The screen frame is connected to the noise reduction cylinder body through bolts and is located at one end of the noise reduction cylinder body. The filter screen is embedded in the inner side of the screen frame. The number of limit blocks is multiple groups, and each group of limit blocks is detachably connected to the screen frame and is respectively located at one end of the screen frame. The number of guide vanes is multiple groups, and each group of guide vanes is fixedly connected to the noise reduction cylinder body and is uniformly distributed on the inner wall of the noise reduction cylinder body.

[0007] Among them, the noise reduction cylinder body further includes a sleeve, a noise reduction cotton cylinder, and a first bolt ear. The noise reduction cotton cylinder is fixedly connected to the sleeve and sleeved on the outer wall of the noise reduction cotton cylinder. The number of the first bolt ears is multiple groups, and each group of the first bolt ears is fixedly connected to the sleeve and located on the outer wall of the sleeve respectively.

[0008] Among them, the inner wall of the noise reduction cotton cylinder has pits. The number of the pits is multiple groups, and multiple groups of the pits are evenly distributed on the inner wall of the noise reduction cotton cylinder.

[0009] Among them, each group of the guide vanes includes a first blade body, a second blade body, and a noise reduction sponge sheet. The noise reduction sponge sheet is fixedly connected to the first blade body and located on one side of the first blade body. The second blade body is fixedly connected to the noise reduction sponge sheet and located on one side of the noise reduction sponge sheet.

[0010] Among them, each group of the limit blocks includes a clamping block and a locking screw. One end of the clamping block has an opening. The locking screw is threadedly connected to the clamping block and located on one side of the clamping block. One end of the locking screw penetrates through the clamping block and is placed inside the opening.

[0011] Among them, the mesh frame includes a frame body and a second bolt ear. The second bolt ear is fixedly connected to the frame body and located on the outer wall of the frame body. The inner wall of the frame body has a boss structure.

[0012] Among them, the noise reduction mechanism further includes support legs. The number of the support legs is two groups, and two groups of the support legs are fixedly connected to the noise reduction cylinder body and located on the outer wall of the noise reduction cylinder body respectively.

[0013] A structure of the air guide cover for a generator set. The main body of the air guide cover is installed at one end of the generator set. The noise reduction cylinder is installed at one end of the air guide cover body through bolts. The wire frame is installed at one end of the noise reduction cylinder through bolts. Multiple groups of the guide vanes are evenly installed on the inner wall of the noise reduction cylinder. The evenly distributed guide vanes can guide and disturb the incoming air flow, making the air flow more evenly distributed in the entire noise reduction cylinder and the main body of the air guide cover, reducing the stagnant areas of the air flow, accelerating the convective heat transfer speed between heat and air, enabling the cooling air to fully contact the heating components of the generator set, taking away more heat, and improving the overall heat dissipation efficiency. The noise reduction cylinder can also extend the chamber of the main body of the air guide cover. The flow path of the air flow in the main body of the air guide cover and the noise reduction cylinder becomes longer. The extended chamber can buffer and rectify the air flow, making the air flow more stable and uniform in the main body of the air guide cover, reducing the turbulence and vortex phenomena of the air flow, improving the uniformity and consistency of heat dissipation. The stable air flow can reduce the generation of noise. When the air flow flows in the chamber, the noise can be gradually weakened through reflection, refraction, and absorption, thereby reducing the noise generated by the air flow. The filter screen is installed on the inner side of the wire frame through the limit block, used to filter external impurities and prevent external foreign objects from entering the main body of the air guide cover. The noise reduction cylinder can be disassembled and assembled according to actual needs, thereby further improving the diversity and flexibility of the structure of the air guide cover for the generator set. The above structure settings can effectively extend the cavity of the main body of the air guide cover, achieve the purpose of air intake and noise reduction, reduce the impact of the generator set on the surrounding environment during operation, reduce the generation of noise, and effectively avoid noise pollution.

Detailed implementation manner

[0020] Please refer to Figures 1 to 4

[0021] This invention provides a structure of an air guide cover for a generator set, including an air guide cover main body 101, and further including a noise reduction mechanism. The noise reduction mechanism includes a noise reduction cylinder body, flow guiding vanes 102, a filter screen 103, a net frame and limit blocks. The noise reduction cylinder body is communicated with the air guide cover main body 101 through bolts and is located at one end of the air guide cover main body 101. The net frame is communicated with the noise reduction cylinder body through bolts and is located at one end of the noise reduction cylinder body. The filter screen 103 is embedded in the inner side of the net frame. The number of the limit blocks is multiple groups, and each group of the limit blocks is detachably connected to the net frame and is respectively located at one end of the net frame. The number of the flow guiding vanes 102 is multiple groups, and each group of the flow guiding vanes 102 is fixedly connected to the noise reduction cylinder body and is evenly distributed on the inner wall of the noise reduction cylinder body.In this embodiment, the air guide hood main body 101 is installed at one end of the generator set. The noise reduction cylinder body is installed at one end of the air guide hood body through bolts. The mesh frame is installed at one end of the noise reduction cylinder body through bolts. Multiple groups of the guide vanes 102 are evenly installed on the inner wall of the noise reduction cylinder body. The evenly distributed guide vanes 102 can guide and disturb the incoming air flow, making the air flow more evenly distributed in the entire noise reduction cylinder body and the air guide hood main body 101, reducing the stagnant area of the air flow, accelerating the convective heat transfer speed between heat and air, enabling the cooling air to fully contact the heat-generating components of the generator set, taking away more heat, and improving the overall heat dissipation efficiency. The noise reduction cylinder body can also extend the chamber of the air guide hood main body 101. The flow path of the air flow in the air guide hood main body 101 and the noise reduction cylinder body becomes longer. Extending the chamber can buffer and rectify the air flow, making the air flow more stable and uniform in the air guide hood main body 101, reducing the turbulence and eddy current phenomena of the air flow, improving the uniformity and consistency of heat dissipation. The stable air flow can reduce the generation of noise. Extending the chamber, when the air flow flows in the chamber, the noise can be gradually weakened through reflection, refraction, and absorption, thereby reducing the noise generated by the air flow. The filter net 103 is installed on the inner side of the mesh frame through the limit block, used to filter external impurities, and prevent external foreign objects from entering the air guide hood main body 101. The noise reduction cylinder body can be disassembled and assembled according to actual needs, thereby further improving the diversity and flexibility of the generator set air guide hood structure.

[0022] Furthermore, the noise reduction cylinder body further includes a sleeve 104, a noise reduction cotton cylinder 105, and a first bolt ear 106. The noise reduction cotton cylinder 105 is fixedly connected to the sleeve 104 and sleeved on the outer wall of the noise reduction cotton cylinder 105. The number of the first bolt ears 106 is multiple groups. Each group of the first bolt ears 106 is respectively fixedly connected to the sleeve 104 and is respectively located on the outer wall of the sleeve 104.

[0023] In this embodiment, the noise reduction cotton cylinder 105 is sleeved on the outer wall of the sleeve 104 to reduce the noise inside the sleeve 104. At the same time, the sleeve 104 is fixed to one end of the air guide hood main body 101 through multiple groups of the first bolt ears 106, and further noise reduction is carried out through the noise reduction cotton cylinder 105.

[0024] Furthermore, the inner wall of the noise reduction cotton cylinder 105 has pits 107. The number of the pits 107 is multiple groups. Multiple groups of the pits 107 are evenly distributed on the inner wall of the noise reduction cotton cylinder 105.

[0025] In this embodiment, the arrangement of multiple groups of the pits 107 causes reflection and refraction when sound waves conduct to the inside of the sound-absorbing cotton cylinder 105, and the sound waves are emitted and propagated multiple times inside the pits 107. The energy of the sound waves is gradually dissipated during this process, thereby reducing the intensity of the sound waves and achieving the purpose of effective energy absorption and noise reduction.

[0026] Further, each group of the flow guide pieces 102 includes a first piece body 108, a second piece body 109, and a sound-absorbing sponge piece 110. The sound-absorbing sponge piece 110 is fixedly connected to the first piece body 108 and is located on one side of the first piece body 108. The second piece body 109 is fixedly connected to the sound-absorbing sponge piece 110 and is located on one side of the sound-absorbing sponge piece 110.

[0027] In this embodiment, the first piece body 108 and the second piece body 109 clamp the sound-absorbing sponge piece 110, and at the same time, both the first piece body 108 and the second piece body 109 are fixedly connected to the sleeve 104. After the air flow flows into the sleeve 104, the air flow is shunted by multiple groups of the flow guide pieces 102 to ensure the stability of the air flow. At the same time, a sound-absorbing sponge piece 110 for absorbing sound waves is arranged inside each group of the flow guide pieces 102 to absorb the energy of the sound waves generated by the air flow inside the sleeve 104 for noise reduction.

[0028] Further, each group of the limit blocks includes a clamping block 111 and a locking screw 112. One end of the clamping block 111 has an opening. The locking screw 112 is threadedly connected to the clamping block 111 and is located on one side of the clamping block 111, and one end of the locking screw 112 penetrates through the clamping block 111 and is placed inside the opening.

[0029] In this embodiment, the clamping block 111 is clamped on the outer wall of the wire frame to install and fix the filter net 103. The outer wall of the wire frame is extruded by the locking screw 112, and thus the clamping block 111 is fixed to the outer wall of the wire frame through the locking screw 112 for limiting the installation of the filter net 103.

[0030] Further, the wire frame includes a frame body 113 and a second bolt ear 114. The second bolt ear 114 is fixedly connected to the frame body 113 and is located on the outer surface wall of the frame body 113. The inner wall of the frame body 113 has a boss structure.

[0031] In this embodiment, the housing 113 is used to install and fix the filter screen 103. At the same time, the provision of the boss structure can effectively ensure the stability of the filter screen 103 after installation. The housing 113 is fixedly connected to the noise reduction cylinder body through a plurality of groups of the second bolt ears 114 by bolts, and can also be fixedly connected to the air guide cover body 101 through the second bolt ears 114 by bolts.

[0032] Furthermore, the noise reduction mechanism further includes support legs. The number of the support legs is two groups. The two groups of support legs are respectively fixedly connected to the noise reduction cylinder body and are respectively located on the outer wall of the noise reduction cylinder body.

[0033] In this embodiment, the provision of the support legs can support the noise reduction cylinder body after the installation of the noise reduction cylinder body, avoiding large fluctuations due to insufficient stability during operation caused by extending its cavity. The use stability of the noise reduction cylinder body can be effectively improved through the support legs.

[0034] Furthermore, each group of support legs includes a mounting block 115, a first support shaft 116, a second support shaft 117, and a support panel 118. The mounting block 115 is fixedly connected to the noise reduction cylinder body and is located on the outer wall of the noise reduction cylinder body. The first mounting shaft is rotatably connected to the mounting block 115 and is located at one end of the mounting block 115. The second support shaft 117 is rotatably connected to the first support shaft 116 and is located at one end of the first support shaft 116. The support panel 118 is fixedly connected to the second support shaft 117 and is located at one end of the second support shaft 117.

[0035] In this embodiment, the mounting block 115 mounts the first support shaft 116. At the same time, the second support shaft 117 is rotatably connected to the end of the first support shaft 116 away from the mounting block 115. By flexibly adjusting the first support shaft 116 and the second support shaft 117, it can be adapted to different environments. Finally, the support panel 118 contacts the ground, thereby realizing the support of the support legs for the noise reduction cylinder body and providing the stability of the noise reduction cylinder body.

[0036] Furthermore, the support panel 118 includes a main board body 119 and a rubber plate 120. The main board body 119 is fixedly connected to the second support shaft 117 and is located at one end of the second support shaft 117. The rubber plate 120 is fixedly connected to the main board body 119 and is located at the lower end of the main board body 119.

[0037] In this embodiment, the main board body 119 increases the contact area with the ground, thereby improving the support stability of the support leg for the noise reduction cylinder body. The rubber plate 120 can effectively improve the stability of the support of the main board body 119, play an effective anti-slip role, and avoid the displacement of the main board body 119 during the support operation.

[0038] The above-disclosed is only a preferred embodiment of the present invention. Of course, it cannot be used to limit the scope of the rights of the present invention. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present invention still fall within the scope covered by the invention.
