Description

Technical Field

[0001] This application relates to the field of generator sets, specifically to a corrosion-resistant containerized generator set. Background Technology

[0002] Containerized generator sets are widely used in corrosive environments such as mines, ports, and ships (e.g., salt spray, acid rain, high temperature and high humidity environments). Their core requirement is to protect the mechanical structure of the generator set from corrosion.

[0003] Chinese patent document CN210858942U discloses a containerized generator set, specifically disclosing a container; a first partition and a second partition, disposed inside the container, dividing the container's interior from left to right into a first exhaust chamber, a generator chamber, and a second exhaust chamber; a first generator set and a second generator set, respectively disposed at the left and right ends of the generator chamber, with the heat generated by the first and second generator sets during operation being discharged to the first and second exhaust chambers respectively; a fuel tank, disposed in the middle of the generator chamber, for supplying fuel to the first and second generator sets; a control device, electrically connected to the first and second generator sets respectively, for controlling the operation or shutdown of the first and / or second generator sets; and a first exhaust double-leaf door and a second exhaust double-leaf door, respectively disposed on the left and right sides of the container, allowing the heat discharged into the first and second exhaust chambers to escape from the container.

[0004] However, the silencers in the aforementioned patents are directly installed on the container using self-tapping screws or rivets, which easily accumulate corrosive media, induce electrochemical corrosion, and lead to loosening of the connection, reducing the noise reduction effect and structural lifespan. Utility Model Content

[0005] In order to overcome the problem of easy corrosion at the connection between the muffler and the container in the prior art, this application provides a corrosion-resistant containerized generator set.

[0006] This application adopts the following technical solution: a corrosion-resistant containerized generator set, including a container body and a generator set body. A mounting base is provided on the inner bottom of the container body, and the generator set body is adapted to be installed on the mounting base. An exhaust pipe is provided on the top of the generator set body, and the exhaust pipe extends upward to the top of the container body. A muffler is provided on the exhaust pipe, and the muffler is located on the outside of the container body. A perforation is provided at the bottom of the container body, and the exhaust pipe passes through the perforation.

[0007] The exhaust pipe is provided with two flanges. One flange is installed on the top outer side of the container body, and the other flange is installed on the top inner side of the container body. Both flanges are provided with several connection holes, which are located away from the exhaust pipe. Locking bolts are provided in the two coaxially arranged connection holes.

[0008] Optionally, a sealing ring is provided between the flange and the container body, and the sealing ring is fitted over the outside of the perforation.

[0009] Optionally, the top of the flange located on the outside of the container body is provided with an arc surface, which gradually bulges from the outer edge of the flange toward the axial direction of the flange.

[0010] Optionally, at least two sound-absorbing cotton pieces are provided on the inner wall of the container body, and one sound-absorbing cotton piece is provided on the front side and the rear side of the generator set body. Each sound-absorbing cotton piece is provided with several air passages, and the air passages are bent.

[0011] Optionally, the front end of the exhaust pipe is connected to the generator set body via a corrugated pipe, the rear end of the exhaust pipe is bent upward, and a sealing cap is hinged to the rear end of the exhaust pipe, which can be flipped upward.

[0012] Optionally, a door is hinged to the outer wall of the container body, and a control panel is provided on the outside of the door body. The control panel is used to adjust the operating parameters of the generator set body, and a cable outlet is provided below the control panel.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] 1. The silencer is installed on the outside of the container body and is connected by flange and locking bolts. The locking bolts are located far from the exhaust pipe, which avoids the problem of corrosive media accumulating in self-tapping screws or rivets. This prevents electrochemical corrosion, avoids loosening of the connection, and improves noise reduction effect and structural life.

[0015] 2. A sealing ring is installed between the flange and the container body to prevent corrosive media from entering the container body through the perforation, further protecting the generator set from corrosion;

[0016] 3. By mounting the generator set body on the mounting base at the bottom inside the container body, the mechanical structure of the generator set can be protected from corrosion. Attached Figure Description

[0024] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] like Figure 1-3 As shown, the corrosion-resistant containerized generator set includes a container body 1, a generator set body 2, an exhaust pipe 21, a silencer 22, and flanges 3. A mounting base 11 is provided on the inner bottom of the container body 1. The mounting base 11 can be a metal bracket welded to the bottom of the container or a metal frame fixed with bolts. The generator set body 2 is fitted onto the mounting base 11. An exhaust pipe 21 is provided on the top of the generator set body 2, extending upwards to the top of the container body 1. A silencer 22 is provided on the exhaust pipe 21, located on the outer side of the container body 1. A through hole 12 is provided at the bottom of the container body 1, through which the exhaust pipe 21 passes. Two flanges 3 on the exhaust pipe 21 are respectively installed on the outer top and inner top of the container body 1. Each flange 3 has several connecting holes 31. Locking bolts are installed in the two coaxially arranged connecting holes 31, and the connecting holes 31 are located away from the exhaust pipe 21. This effectively prevents the accumulation of corrosive media at the installation location of the silencer 22, improving connection stability and structural lifespan.

[0026] A perforation 12 is located at the bottom of the container body 1 to allow the exhaust pipe 21 to pass through. The size of the perforation 12 should be slightly larger than the outer diameter of the exhaust pipe 21 to ensure that the exhaust pipe 21 can pass through smoothly. Two flanges 3 are respectively installed on the outer top and inner top of the container body 1, and are welded to the exhaust pipe 21 or fixedly connected by other means. Connection holes 31 are evenly distributed on the circumference of the flanges 3. By installing locking bolts in the two coaxially arranged connection holes 31, the two flanges 3 are tightly connected together, thereby firmly installing the muffler 22 on the container body 1. Furthermore, a sealing ring is provided between the flanges 3 and the container body 1, and the sealing ring is fitted on the outside of the perforation 12. The sealing ring can be a rubber sealing ring or a silicone sealing ring, etc., and its function is to prevent external moisture, dust and other impurities from entering the container body 1 through the perforation 12, and at the same time, it can further prevent corrosive media from accumulating at the perforation 12. The top of the flange 3 located on the outside of the container body 1 is provided with an arc surface 32, which gradually bulges from the outer edge of the flange 3 towards the axis of the flange 3. This arc surface 32 design allows rainwater and other liquids falling on the flange 3 to slide off quickly, avoiding accumulation on the flange 3 and further reducing the possibility of accumulation of corrosive media.

[0027] At least two sound-absorbing cotton pieces 4 are installed on the inner wall of the container body 1. One sound-absorbing cotton piece 4 is also installed on the front and rear sides of the generator set body 2. Each sound-absorbing cotton piece 4 has several air passages 40, which are bent. The sound-absorbing cotton 4 can be made of glass wool or polyester fiber, etc., and its function is to absorb the noise generated during generator operation. The bent design of the air passages 40 increases the propagation path of noise within the sound-absorbing cotton 4, improving the noise absorption effect. The front end of the exhaust pipe 21 is connected to the generator set body 2 via a corrugated pipe 211, which compensates for the relative displacement between the exhaust pipe 21 and the generator set body 2, reducing vibration transmission. The rear end of the exhaust pipe 21 is bent upwards, and a sealing cap 212 is hinged to the rear end of the exhaust pipe 21. The sealing cap 212 can be flipped upwards. When the generator set is running, the sealing cover 212 flips upward and opens under the pressure of the exhaust gas, and the exhaust gas is discharged; when the generator set stops running, the sealing cover 212 closes under its own gravity to prevent external dust, moisture and other impurities from entering the exhaust pipe 21.

[0028] A door 13 is hinged to the outer wall of the container body 1. A control panel 14 is located on the outside of the door 13. The control panel 14 is used to adjust the operating parameters of the generator set body 2, such as power and speed. The control panel 14 can be a touch screen or a button-type control panel, etc., for convenient operation by the operator. A cable outlet 15 is located below the control panel 14 for leading out cables to supply power to external equipment.

[0029] The implementation principle of this embodiment is as follows: This corrosion-resistant containerized generator set uses a flange 3 to connect the silencer 22 and the container body 1, avoiding the problem of corrosive media accumulating easily in traditional connection methods, thus improving the stability of the connection and the service life of the structure. At the same time, by setting up structures such as sealing rings, arc surfaces 32, sound-absorbing cotton 4, corrugated pipes 211, and sealing covers 212, the protective performance, noise reduction effect, and operational stability of the generator set are further improved.

[0030] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
