Description

Technical Field

[0001] The utility model belongs to the technical field of generator sets, and particularly relates to an external cooling mechanism for a generator set. Background Art

[0002] A generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy. It consists of a power system, a control system, a sound insulation system, a shock absorption system, and an exhaust system. It is driven by a water turbine, a steam turbine, a diesel engine, or other power machinery, and converts the energy generated by the flow of water, air flow, fuel combustion, or nuclear fission into mechanical energy and transmits it to the generator. Then, the generator converts it into electrical energy and finally outputs it to electrical equipment for use.

[0003] In the process of implementing the present utility model, the inventor found that there are at least the following problems in this technology: when the generator set is running, since the components on it continuously generate heat, it is necessary to cool it to ensure its continuous and stable operation. In the current cooling mechanism of the generator set, the structure position of the cooling mechanism on it is usually fixed, so it can only dissipate heat at a designated position (for example, the patent with the application number CN202021366903.9 - a cooling mechanism for a generator set). Since the shapes, heights, etc. of different parts of the components on the generator set are different, it is impossible to take good care of the cooling of each part of the components on the generator set.

[0004] Therefore, we propose an external cooling mechanism for a generator set to solve the above problems. Content of the Utility Model

[0005] The main purpose of the present utility model is to provide an external cooling mechanism for a generator set, which is convenient for closely and fully dissipating heat from different parts with different heights on the generator set, improving the cooling effect and range, and enabling each part on the generator set to receive a good cooling effect, and can effectively solve the problems in the background art.

[0006] To achieve the above purpose, the present utility model adopts the following technical solutions:

[0007] An external cooling mechanism for a generator set includes a generator set base, side seats symmetrically welded on both sides of the generator set base, and a cooling module located on the generator set base. An installation groove is formed on one of the side seats, and a motor is horizontally installed in the installation groove on the side seat. Side grooves are respectively formed on the opposite sides of the two side seats, and a screw rod and a limiting rod are respectively arranged in the two side grooves. The output shaft of the motor is coaxially connected to the screw rod. The motor needs to be powered by an external power facility, and both sides of the limiting rod are welded to the side seat;

[0008] An inverted U-shaped support frame is provided above the base of the generator set, wherein inner slides are welded on both sides of the support frame, one of the inner slides is threadedly sleeved on the screw, and the other inner slide is slidably sleeved on the limit rod. A cylinder is installed at the center of the top wall of the support frame, and an extension plate is connected below the cylinder. The cooling module includes three fans fixed below the extension plate. The fans require external power supply to power them. The fans on both sides are designed to be inclined at 45°. The fans on both sides are connected to the extension plate through an edge support rod, and the fan in the center is connected to the extension plate through two symmetrically designed center support rods. This connection method is an existing technology and can be fixed bonding or other methods.

[0009] Preferably, the screw and the limiting rod are both arranged horizontally, and both sides of the screw are rotatably connected to the side seats; so that the screw can operate stably under the drive of the motor.

[0010] Preferably, rollers are installed on the top and bottom walls of the inner slide, and strip grooves are formed on the upper and lower sides of the side groove, respectively, and the two rollers run in the two strip grooves respectively; and the wheels on the rollers are in contact with the inner walls of the strip grooves, so that when the inner slide moves horizontally, the two rollers are driven to roll in the two strip grooves, making the inner slide more stable.

[0011] Preferably, sliding bars are symmetrically welded on both sides of the top wall of the extension plate, and the two sliding bars are vertically arranged and slide through the support frame; so that when the extension plate is raised or lowered, the two sliding bars are driven to slide on the support frame, thereby making the extension plate more stable.

[0012] Preferably, fan guards are installed at the openings on both sides of the fan, and the wind direction of the fan is from top to bottom; thereby facilitating cooling of the generator set on the generator set base.

[0013] In summary, the technical effects and advantages of the utility model are:

[0014] The generator set uses an external cooling mechanism. By setting a horizontally movable cooling module on the generator set base, and the cooling module can be raised and lowered, it is convenient to fully dissipate heat from parts of the generator set at different heights at close range, improving the cooling effect and range, so that all parts of the generator set are well cooled.

[0015] The generator set uses an external cooling mechanism to power on the three fans and create a downward-blowing air duct, which blows directly toward the generator set. Furthermore, the drive cylinder drives the extension plate to rise and fall to change the height of the three fans. The drive motor drives the screw to move, so that the support frame and the two inner slides move horizontally along the limit rod. The cooling module can be moved above different components on the generator set, and different components on the generator set can be cooled at close range, so that the cooling effect is better.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figures 1 - 5 , an external cooling mechanism for a generator set, comprising a generator set base 1, side seats 2 symmetrically welded to both sides of the generator set base 1, and a cooling module located on the generator set base 1, wherein a mounting groove is formed on one of the side seats 2, a motor 3 is horizontally mounted in the mounting groove on the side seat 2, side grooves 4 are respectively formed on opposite sides of the two side seats 2, a screw 5 and a limiting rod 6 are respectively provided in the two side grooves 4, wherein the output shaft of the motor 3 is coaxially connected to the screw 5, the motor 3 requires power from an external power facility, both sides of the limiting rod 6 are welded to the side seat 2, the screw 5 and the limiting rod 6 are both horizontally arranged, and both sides of the screw 5 are rotatably connected to the side seat 2, so that the screw 5 can operate stably under the drive of the motor 3;

[0024] Above the base 1 of the generator set, there is an inverted U-shaped support frame 10. Inner sliding seats 7 are welded to both sides of the support frame 10. One of the inner sliding seats 7 is threadedly sleeved on the screw rod 5, and the other inner sliding seat 7 is slidably sleeved on the limiting rod 6. Rollers 8 are installed on both the top wall and the bottom wall of the inner sliding seat 7. Strip-shaped grooves 9 are respectively formed on the upper and lower sides of the side groove 4. The two rollers 8 respectively run in the two strip-shaped grooves 9, and the wheels on the rollers 8 contact the inner walls of the strip-shaped grooves 9, so that when the inner sliding seat 7 translates, it drives the two rollers 8 to roll in the two strip-shaped grooves 9, making the inner sliding seat 7 more stable;

[0025] At the center of the top wall of the support frame 10, a cylinder 11 is installed. An extension plate 12 is connected below the cylinder 11. Slide rods 13 are symmetrically welded to both sides of the top wall of the extension plate 12. The two slide rods 13 are both vertically arranged and slid through the support frame 10, so that when the extension plate 12 rises and falls, it drives the two slide rods 13 to slide on the support frame 10, thus making the extension plate 12 more stable. The cooling module includes three fans 14 fixed below the extension plate 12. The fans 14 need an external power supply to supply power to them. The fans 14 located on both sides are both designed to be inclined at 45°;

[0026] In addition, fan grilles 15 are installed at the openings on both sides of the fans 14 to protect the fan blades inside the fans 14, and the wind direction of the fans 14 is from top to bottom, so as to facilitate cooling the generator set on the base 1 of the generator set. The fixing method of the fans 14 is as follows: The fans 14 located on both sides are both connected to the extension plate 12 through an edge support rod 17, and the fan 14 located at the center is connected to the extension plate 12 through two symmetrically designed center support rods 16. This connection method is the prior art and can be fixed bonding or other methods.

[0027] For the external cooling mechanism of the generator set: During installation, the generator set is fixed to the base 1 of the generator set by all methods in the prior art; when the generator set is running, the components on it will continuously generate heat, so cooling is required. At this time, the three fans 14 can be powered on and run to create a downward blowing air duct, so as to blow directly at the generator set. And because the heights of different parts of the components on the generator set are different, the cylinder 11 can be driven to run to drive the extension plate 12 to rise and fall, so as to change the heights of the three fans 14. At the same time, the motor 3 is driven to run to drive the screw rod 5 to rotate, so that the support frame 10 and the two inner sliding seats 7 translate along with the limiting rod 6, so that the cooling module can be moved above different parts of the components on the generator set and the height can be adjusted to perform close cooling work on different parts of the components on the generator set, making the cooling effect better.

[0028] The above are only the preferred specific embodiments 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, according to the technical solution and the inventive concept of the present utility model, with equivalent substitution or change, shall be covered by the protection scope of the present utility model.
