Description

Technical Field

[0001] This invention relates to the field of power station box technology, specifically a diesel power station box. Background Technology

[0002] A diesel generator set is a power generation device that uses diesel fuel as its primary fuel. It uses a diesel engine to drive a generator (i.e., an electric generator) to generate electricity, converting kinetic energy into electrical and thermal energy. A complete diesel generator set mainly consists of three parts: 1. a diesel engine, 2. a generator (i.e., an electric generator), and 3. a controller. Depending on the specific needs of different locations, generator sets are available in stationary and mobile trailer configurations. To reduce noise and minimize disruption to work and daily life, a metal enclosure is installed around the generator set, lined with sound-absorbing material, thus protecting the generator set from all sides.

[0003] Currently, diesel generator sets are installed inside enclosures. While these enclosures can provide sound insulation and noise reduction during operation, they cannot address the root cause of noise generation from vibration. The continuous vibration of the generator sets exacerbates installation wear and tear. Furthermore, the enclosures hinder heat dissipation, causing heat to accumulate inside and resulting in high operating temperatures. This is especially true for the bottom surface where the generator sets are installed, which is further hampered by the enclosure and the obstruction from the mounting surface, making heat dissipation even more difficult. Summary of the Invention

[0026] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0027] like Figures 1 to 6As shown, the diesel power station box in this embodiment includes a power station box base 1. A noise reduction box 2 is located on the top of the power station box base 1, and a box cover 3 is located on the top of the noise reduction box 2. The interior of the noise reduction box 2 has an accommodating space. A heat dissipation seat 4 is located at the lower end of the interior of the noise reduction box 2, and a heat dissipation mechanism is provided on the heat dissipation seat 4. A support seat 8 is located at the bottom of the inner side of the noise reduction box 2. A vibration damping platform 5 is located inside the noise reduction box 2 between the support seat 8 and the heat dissipation seat 4. Several vibration damping seats 51 are located on the top of the vibration damping platform 5. Guide holes are provided at both opposite ends of the vibration damping platform 5. Guide rods 52 are provided between the opposite ends of the bottom of the heat dissipation seat 4 and the support seat 8. The vibration damping platform 5 is slidably mounted with the guide rods 52 through the guide holes. An adjustment mechanism 6 is provided between the bottom of the vibration damping platform 5 and the support seat 8. Fixing mechanisms 7 are provided on both opposite ends of the top of the noise reduction box 2 of the heat dissipation seat 4. The noise reduction enclosure 2 houses a diesel generator set 9. A base plate 91 is located at the bottom of the diesel generator set 9. The diesel generator set 9 is mounted on top of the heat sink 4 via a fixing mechanism 7. A shock-absorbing seat 51 is located inside the heat sink 4 and contacts the base plate 91. A cooling fan 10 is located on one side of the noise reduction enclosure 2, and a maintenance panel 11 is located on the other side. The maintenance panel 11 has a dustproof and heat dissipation inlet 111, enabling the diesel generator set 9 to be installed on the heat sink 4 for heat dissipation. This provides the diesel power station enclosure with excellent heat dissipation performance, solving the problem of obstructed heat dissipation during the installation of the diesel generator set 9 inside the enclosure. The installation of the diesel generator set 9 combines heat dissipation and shock absorption functions. The shock absorption intensity is adjustable, reducing the operating noise of the diesel power station enclosure. The diesel generator set 9 is flexibly clamped for easy installation and disassembly.

[0028] Specifically, the heat dissipation mechanism includes a heat dissipation groove 41, heat dissipation fins 42, support blocks 43, and flow ports 44. The heat dissipation base 4 has a heat dissipation groove 41 in the middle, and a number of heat dissipation fins 42 are evenly distributed inside the heat dissipation groove 41. Flow ports 44 are provided on the heat dissipation base 4 at both ends of the heat dissipation fins 42. A number of support blocks 43 are provided inside the flow ports 44. The support blocks 43 are arranged one-to-one with the heat dissipation fins 42. The top of the heat dissipation fins 42 is set at the same height as the top of the heat dissipation base 4. The shock-absorbing seat 51 is set between two adjacent heat dissipation fins 42. The flow port 44 on one side of the heat dissipation base 4 is set close to the cooling fan 10, and the flow port 44 on the other side of the heat dissipation base 4 is set close to the dustproof heat dissipation inlet 111. The heat dissipation fins 42 set inside the heat dissipation groove 41 cooperate with the cooling fan 10 and the dustproof heat dissipation inlet 111 for efficient heat dissipation.

[0029] Furthermore, the adjustment mechanism 6 includes an adjustment groove 61, a bidirectional screw 62, a servo motor 63, a threaded sleeve 64, a connecting block 65, and an adjustment rod 66. The top of the support base 8 is provided with an adjustment groove 61, and the inside of the adjustment groove 61 is provided with a bidirectional screw 62. One end of the bidirectional screw 62 is connected to the output end of the servo motor 63 on the support base 8 through a coupling. Two threaded sleeves 64 are symmetrically threaded on the bidirectional screw 62. The top of the two threaded sleeves 64 and the bottom of the shock absorber 5 are provided with connecting blocks 65. An adjustment rod 66 is provided on the connecting block 65 through a shaft pin. There are two adjustment rods 66. The two adjustment rods 66 are located between the shock absorber 5 and the threaded sleeves 64 through the connecting block 65, making it convenient to adjust the height of the shock absorber 5.

[0030] Furthermore, the fixing mechanism 7 includes a locking screw 71 and a locking plate 72. Locking screws 71 are provided on the noise reduction housing 2 on both sides of the top of the heat sink 4. One end of the locking screw 71 passes through the noise reduction housing 2 and is connected to the locking plate 72. The locking plate 72 is arranged in an L-shape. An elastic pad is provided on the side of the locking plate 72 away from the locking screw 71, so that the locking plate 72 can be elastically clamped to the base plate 91 and can cooperate with the shock absorber 51 to achieve elastic installation of the base plate 91 on the heat sink 4. The installation shock absorption performance is better, and the diesel generator set 9 is easy to install and remove on the heat sink 4.

[0031] Furthermore, a limiting block is integrally provided at the bottom of the locking plate 72, and a limiting groove is provided at the top of the heat sink 4 at the bottom of the locking plate 72. A limiting rod 73 is provided inside the limiting groove, and a guide hole is provided on the limiting block. The limiting block is slidably mounted on the limiting rod 73 through the guide hole. The base plate 91 and the diesel generator set 9 are arranged in a T-shaped structure. The limiting rod 73 can limit the locking plate 72. Combined with the clamping of the locking plate 72 on the base plate 91 and the shock-absorbing support of the shock-absorbing seat 51 on the base plate 91, the locking plate 72 is reliably clamped to the base plate 91.

[0032] Furthermore, the noise reduction enclosure 2 is designed with a double-layer structure consisting of an outer shell and an inner shell. The outer shell and the inner shell are connected by a supporting keel to form a hollow sandwich. The inner surface of the inner shell is provided with a sound insulation layer, and the surface of the sound insulation layer is provided with sound absorption holes. The noise reduction enclosure 2 itself has good sound insulation and noise reduction performance for the diesel generator set 9 installed inside.

[0033] The method of use in this embodiment is as follows: Place the diesel generator set 9 in the heat sink 4 of the noise reduction housing 2. The heat dissipation fins 42 in the heat dissipation groove 41 are in contact with the bottom plate 91 of the diesel generator set 9. Utilize the thermal conductivity of the heat dissipation fins 42 to transfer the heat generated by the diesel generator set 9 to the surrounding air. Tighten the locking screw 71 on the noise reduction housing 2. The limiting block slides on the limiting rod 73, and the locking plate 72 is engaged with the bottom plate 91 to clamp and fix the diesel generator set 9 on the heat sink 4. Installation: The limiting rod 73 limits the locking plate 72, and in conjunction with the shock absorber 51 inside the heat sink 4, the diesel generator set 9 is elastically clamped and installed, making disassembly and assembly convenient. The servo motor 63 drives the bidirectional screw 62 inside the adjusting groove 61 to rotate. The two threaded sleeves 64 symmetrically arranged on the threads of the bidirectional screw 62 move closer or further apart, adjusting the adjusting rod 66 connected between the threaded sleeves 64 and the shock absorber 5 via the connecting block 65, thereby adjusting the height of the shock absorber 5. The shock absorber 5 moves at the upper limit of the guide rod 52. The vibration damping seat 51 at the top of the vibration damping platform 5 is adjusted synchronously with the vibration damping platform 5, so that the vibration damping seat 51 passes through the heat sink 4 to provide vibration damping support for the diesel generator set 9 installed on the heat sink 4. The vibration damping seat 51 at the top of the vibration damping platform 5 is located inside the heat sink 4. The vibration damping seat 51 and the heat sink fins 42 are staggered, so that the installation of the diesel generator set 9 has the functions of heat dissipation and vibration damping. At the same time, in conjunction with the adjustment mechanism 6 set on the vibration damping platform 5, the vibration damping intensity of the vibration damping platform 5 and the vibration damping seat 51 can be adjusted to ensure the vibration damping support strength for the installation of the diesel generator set 9, reduce the vibration loss and noise of the diesel power station box during operation. Under the action of the cooling fan 10, the low temperature air outside enters the noise reduction box 2 through the dustproof heat dissipation inlet 111, flows through the flow port 44 through the heat sink 4 and the heat sink fins 42, and the high temperature air inside is discharged by the cooling fan 10 after heat transfer through the heat sink fins 42. This realizes the heat dissipation installation of the diesel generator set 9 on the heat sink 4, so that the diesel power station box has good heat dissipation performance and solves the problem of heat dissipation obstruction of the diesel generator set 9 installed inside the diesel power station box. Example

[0034] The structure of the diesel power station box in this embodiment is basically the same as that in Embodiment 1, except that: the shock absorber seat 51 includes a lower support 511, an upper support 512, a shock absorber groove 513, a shock absorber spring 514, a lower shock absorber pad 515, and an upper shock absorber pad 516 (see...). Figure 7The top of the damping platform 5 is provided with a lower support 511 via a lower damping pad 515. The lower support 511 has a damping groove 513 inside, and an upper support 512 is provided inside the damping groove 513. A damping spring 514 is provided between the upper support 512 and the lower support 511. An upper damping pad 516 is provided on the top of the upper support 512. Limiting grooves are provided on opposite sides inside the lower support 511. A limiting block is provided at the lower end of the upper support 512. The limiting block slides in the limiting groove. The damping spring 513 acts as a damping and buffering device for the upper support 512 to absorb the vibration of the base plate 9. The damping platform 51 has good damping performance.

[0035] Specifically, a pressure sensor is embedded inside the upper shock absorber 516. The output of the pressure sensor is electrically connected to the input of the main control module through the processing module. The output of the main control module is electrically connected to the servo motor 63 and the display screen. When the diesel generator set 9 is not running and generating vibration, the pressure sensor can detect the support of the shock absorber 51 on the base plate 91. Based on the detected pressure data, the shock absorption support elasticity of the shock absorber 51 on the base plate 91 is obtained, thereby adjusting the strength of the shock absorber 51.
