Description

Technical Field

[0001] This invention relates to the field of generator sets, and more particularly to a high-efficiency cooling device for generator sets. Background Technology

[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 noise reduction system, a vibration damping system, and an exhaust system. It is driven by a water turbine, a steam turbine, a diesel engine, or other power machinery. It converts the energy generated by water flow, air flow, fuel combustion, or nuclear fission into mechanical energy, which is then transferred to the generator and converted into electrical energy. The cooling device of the generator set is a device used to dissipate heat and cool down the generator components. Patent CN214998046U discloses a cooling device for a wind turbine generator set, including a housing. Inside the housing is the generator set body, and outside the housing is a drive mechanism for providing power. Ventilation openings are located on both sides of the housing, and an internal ventilation mechanism cooperating with the drive mechanism is located on one side of the housing. A fixed cylinder is located at the top inner part of the housing, and inside the fixed cylinder is a spray mechanism cooperating with the drive mechanism for cooling the generator set body. This invention has a reasonable structure, capable of driving a ventilation fan to rotate, ventilating and cooling the generator set body inside the housing. It can also draw water from a water tank into a sliding cavity, press it into a water pipe, and then spray it out through multiple nozzles for further cooling of the generator set body. The generator set in this patent is sealed inside the casing, making it difficult to expose the generator set during commissioning and maintenance, and increasing the maintenance difficulty. Therefore, we propose a high-efficiency cooling device for generator sets. Summary of the Invention

[0003] Purpose of the invention: The purpose of this invention is to provide a high-efficiency cooling device for generator sets. While ensuring that the cooling effect is better than that of the prior art, it solves the problem of inconvenience in the commissioning and maintenance of generator sets caused by traditional closed-casing cooling devices. By optimizing the structural design, the generator set has an exposed maintenance space, reducing the difficulty of maintenance operations and improving the efficiency of equipment operation and maintenance.

The cooling mechanism includes a protective shell, and there are two protective shells. The bottom of the protective shell is fixedly connected to the upper surface of the slider. The driving mechanism includes an adjusting seat, the left side of which is fixedly connected to the right side of the base plate. The upper surface of the adjusting seat has a through-type movable opening. A pedal is rotatably connected to the right side of the upper surface of the adjusting seat via a hinge. A rack is slidably connected inside the movable opening. The left end of the rack extends through to the left side of the adjusting seat and is rotatably connected to the right end of the push rod via a rotating shaft. Two connecting rods are provided between the pedal and the adjusting seat.

[0005] Furthermore, the outer side wall of the base plate is fixedly connected with multiple mounting feet, and the upper surface of the base plate is detached and installed from the bottom of the generator set body by bolts.

[0006] Furthermore, a sliding rod is fixedly connected inside the groove and located inside the slider.

[0007] Furthermore, two cooling fans and a filter screen are respectively embedded on the opposite sides of the two protective shells.

[0008] Furthermore, a water pump is fixedly connected to the top of the protective housing, and a docking nozzle is embedded and fixedly installed on the top of the protective housing. The top of the docking nozzle is fixedly connected to the output end of the water pump. The bottom of the docking nozzle extends through to the inside of the protective housing and is fixedly connected to a hollow tube. Multiple atomizing nozzles are fixedly connected to the lower outer wall of the hollow tube.

[0009] Furthermore, the top and bottom of the two connecting rods are rotatably connected to a rotating block via a pivot, and the opposite ends of the two rotating blocks are fixedly connected to the opposite sides of the pedal and the rack.

[0010] Furthermore, a lifting port is provided on the right side of the movable opening. A through-type lifting groove is provided on both the front and rear surfaces of the lifting port. A lifting block is slidably connected inside the lifting port. A pressure rod is integrally formed on both the front and rear surfaces of the lifting block. The end of the pressure rod away from the lifting block passes through the lifting groove and is slidably connected to it. A gear two is rotatably connected to the movable opening below the rack two via a rotating shaft. The top of the gear two meshes with the lower surface of the rack two. An L-shaped rack meshes with the lower outer wall of the gear two. The left end of the L-shaped rack extends to the left side of the adjusting seat and is slidably connected to it. Two connecting rods two are provided between the L-shaped rack and the lifting block. Rotating blocks two are rotatably connected to both ends of the two connecting rods two via a rotating shaft. The opposite sides of the two rotating blocks two are closed and fixedly connected to the opposite sides of the L-shaped rack and the lifting block.

[0011] Furthermore, guide blocks are fixedly connected to the front and rear surfaces of the adjusting seat and to the left of the pressure rod. A sliding frame is slidably connected to the outer side of the guide block. An inclined push block is fixedly connected to the right end of the two sliding frames. An L-shaped locking block is integrally formed on the top of the sliding frame and to the left of the guide block. The L-shaped locking block engages with the outer side of the pressure rod, and the top of the L-shaped locking block is an inclined surface.

[0012] Furthermore, a spring is fixedly connected between the adjusting seat and the tilting push block.

[0013] Beneficial effects: This device integrates air cooling and water mist cooling, which can be flexibly switched under different working conditions to meet various heat dissipation needs. Under normal operating conditions, the cooling fan is started, and the outside air enters the protective shell after being filtered by the filter screen to ventilate and dissipate heat from the generator set. The hot air is then discharged from the cooling fan on the other side, effectively removing the heat generated by the unit and ensuring its normal operation. When the unit load increases or the ambient temperature is too high, and air cooling alone cannot meet the heat dissipation requirements, the water pump is started to deliver cooling water to the hollow tube through the docking nozzle. After being atomized by the atomizing nozzle, the water is sprayed onto the surface of the generator set. The water absorbs a large amount of heat during the vaporization process, thereby achieving efficient cooling and ensuring that the generator set can operate stably under harsh conditions such as high temperature and high load. In the closed state, the two protective shells can tightly enclose the generator set, providing it with all-round physical protection, reducing the risk of failure caused by external factors, and extending the service life of the unit. Regarding the drive mechanism, its locking function is ingeniously designed. In the initial state, the L-shaped locking block is tightly engaged with the outside of the pressure rod, restricting the pressure rod from sliding upward, thereby keeping the lifting block fixed. Through a series of linkages and racks, the position of rack two is successfully locked, ensuring that the two protective shells are securely closed. This locking mechanism greatly enhances the stability of the protective shells in the closed state. Even under harsh environmental conditions such as vibration and impact, it can ensure that the protective shells will not be easily opened, creating a safe and stable operating environment for the generator set. In practice, workers can open and close the protective shell with simple foot movements. The operation is simple and intuitive, requiring no complicated tools or professional skills. When the protective shell needs to be opened for maintenance and debugging of the generator set, workers only need to gently press the inclined push block with their heels and push it to the left to easily release the L-shaped locking block's restriction on the pressure rod. Then, by stepping down on the pedal with their toes, the pedal will drive the rack two to move through the linkage, which in turn pulls the rack one of the mounting mechanism to move, ultimately separating the two protective shells in opposite directions. The whole process is seamless, convenient, and quick. After maintenance, closing the protective shell is equally easy. Workers only need to step on the pressure rod to control the protective shell to close again, greatly improving work efficiency and reducing labor intensity. Attached Figure Description

[0016] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Example like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, a high-efficiency cooling device for generator sets is provided, including a mounting mechanism 1; The mounting mechanism 1 includes a base plate 101. Both sides of the base plate 101 are provided with sliding grooves 102. Two sliders 103 are slidably connected to the inner side of the sliding grooves 102. The lower surface of the sliders 103 is rotatably connected to a traction rod 104 via a rotating shaft. The ends of the two traction rods 104 on the same side away from the sliding grooves 102 are rotatably connected to a connecting piece 105 via a rotating shaft. The lower surface of the connecting piece 105 is fixedly connected to a lead screw sleeve 106. A reciprocating screw 107 is installed on the inner side of two screw sleeves 106 with a common thread. Both ends of the reciprocating screw 107 are rotatably connected to a bearing 108 via a rotating shaft. The top of the bearing 108 is fixedly connected to the lower surface of the base plate 101. A gear 109 is fixedly connected to the outer wall of the reciprocating screw 107. A rack 110 is meshed with the outer wall of the gear 109. A guide sleeve 111 is fixedly connected to the lower surface of the base plate 101 and outside the rack 110. A push rod 112 is rotatably connected to the front end of the rack 110 via a rotating shaft. Multiple mounting feet 113 are fixedly connected to the outer side wall of the base plate 101, and the upper surface of the base plate 101 is detached and installed from the bottom of the generator set body 4 by bolts. A slide rod 114 is fixedly connected inside the slide groove 102 and inside the slider 103; When using the mounting mechanism 1, the base plate 101 is first fixed in the designated installation position by multiple mounting feet 113, and then the generator set body 4 is detachably installed on the upper surface of the base plate 101 by bolts. When the position of the cooling mechanism 2 needs to be adjusted, the drive mechanism 3 drives the push rod 112 to pull the rack 110 to slide horizontally along the guide sleeve 111. The rack 110 meshes with the drive gear 109 to rotate, which in turn drives the reciprocating screw 107 to rotate between the two bearings 108. The reciprocating screw 107 drives the two outer screw sleeves 106 to move relative to or away from each other. The screw sleeves 106 pull the traction rod 104 through the connecting piece 105, so that the traction rod 104 drives the slider 103 to slide along the slide rod 114 inside the slide groove 102, thereby realizing the position adjustment of the slider 103 and providing the power basis for the opening and closing of the cooling mechanism 2.

[0018] like Figure 5 As shown, a cooling mechanism 2 is provided above the installation mechanism 1; The cooling mechanism 2 includes a protective shell 201, and there are two protective shells 201. The bottom of the protective shell 201 is fixedly connected to the upper surface of the slider 103. Two cooling fans 202 and a filter screen 207 are respectively installed on the opposite sides of the two protective shells 201; A water pump 203 is fixedly connected to the top of the protective housing 201. A docking nozzle 204 is embedded and fixedly installed on the top of the protective housing 201. The top of the docking nozzle 204 is fixedly connected to the output end of the water pump 203. The bottom of the docking nozzle 204 extends through to the inside of the protective housing 201 and is fixedly connected to a hollow tube 205. Multiple atomizing nozzles 206 are fixedly connected to the lower side of the outer wall of the hollow tube 205. When the cooling mechanism 2 is closed, the two protective shells 201 form a protective enclosure around the generator set body 4. When the cooling fan 202 is started, the outside air enters the inside of the protective shell 201 after being filtered by the filter screen 207, and ventilates and cools the generator set body 4. The hot air is discharged from the cooling fan 202 on the other side of the protective shell 201. When enhanced cooling is required, water pump 203 is started. Water pump 203 delivers cooling water through docking nozzle 204 to hollow tube 205, and then atomizes it through multiple atomizing nozzles 206 before spraying it onto the surface of generator body 4 to achieve water mist cooling. When the slider 103 of the mounting mechanism 1 slides back to back, the slider 103 drives the two protective shells 201 to separate back to back, exposing the generator body 4, which is convenient for maintenance and debugging. When the slider 103 slides relative to each other, the two protective shells 201 close and return to the cooling and protection state.

[0019] like Figure 6 and Figure 7 As shown, the generator set body 4 is installed above the installation mechanism 1 and inside the cooling mechanism 2; A drive mechanism 3 is provided on the right side of the mounting mechanism 1; The drive mechanism 3 includes an adjustment seat 301. The left side of the adjustment seat 301 is fixedly connected to the right side of the base plate 101. A through-type movable opening 302 is provided on the upper surface of the adjustment seat 301. A pedal 303 is rotatably connected to the right side of the upper surface of the adjustment seat 301 via a hinge. A rack 304 is slidably connected inside the movable opening 302. The left end of the rack 304 extends through to the left side of the adjustment seat 301 and is rotatably connected to the right end of the push rod 112 via a rotating shaft. Two connecting rods 305 are provided between the pedal 303 and the adjustment seat 301. The top and bottom of the two connecting rods 305 are rotatably connected to a rotating block 306 via a rotating shaft. The opposite ends of the two rotating blocks 306 are fixedly connected to the opposite sides of the pedal 303 and the rack 304, respectively. A lifting port 307 is provided on the right side of the movable port 302. Both the front and rear surfaces of the lifting port 307 have through-type lifting grooves 308. A lifting block 309 is slidably connected inside the lifting port 307. A pressure rod 310 is integrally formed on both the front and rear surfaces of the lifting block 309. The end of the pressure rod 310 away from the lifting block 309 passes through the lifting groove 308 and is slidably connected to it. A gear 311 is rotatably connected to the interior of the movable port 302, below the rack 304, via a rotating shaft. The top of 11 meshes with the lower surface of rack 304. An L-shaped rack 312 meshes with the lower side of the outer wall of gear 311. The left end of the L-shaped rack 312 extends to the left side of the adjusting seat 301 and is slidably connected to the adjusting seat 301. Two connecting rods 313 are provided between the L-shaped rack 312 and the lifting block 309. Rotating blocks 314 are rotatably connected between the two ends of the two connecting rods 313 through a rotating shaft. The opposite sides of the two rotating blocks 314 are closed and fixedly connected to the opposite sides of the L-shaped rack 312 and the lifting block 309. Guide blocks 315 are fixedly connected to the front and rear surfaces of the adjusting seat 301 and to the left of the pressure rod 310. A sliding frame 316 is slidably connected to the outer side of the guide block 315. An inclined push block 317 is fixedly connected to the right end of the two sliding frames 316. An L-shaped locking block 318 is integrally formed on the top of the sliding frame 316 and to the left of the guide block 315. The L-shaped locking block 318 is engaged with the outer side of the pressure rod 310. The top of the L-shaped locking block 318 is an inclined surface. A spring 319 is fixedly connected between the adjusting seat 301 and the tilting push block 317. When the drive mechanism 3 controls the cooling mechanism 2 to close, in the initial state, the L-shaped locking block 318 is engaged on the outside of the pressure rod 310, restricting the pressure rod 310 from sliding upward along the lifting groove 308, so that the lifting block 309 remains fixed, and then the position of the rack 304 is locked by the connecting rod 313, the L-shaped rack 312, and the gear 311, ensuring that the two protective shells 201 are stably closed. When the cooling mechanism 2 needs to be separated, press the inclined push block 317 against the heel and push the inclined push block 317 to the left. The inclined push block 317 compresses the spring 319 and drives the two sliding frames 316 to move to the left along the guide block 315. The sliding frames 316 drive the L-shaped locking block 318 to disengage from the pressure rod 310 and release the limit. Then, by stepping down on the pedal 303 with the toes, the pedal 303 pushes the rack 304 to slide to the left along the movable opening 302 via two connecting rods 305. The rack 304 drives the push rod 112 to pull the rack 110 of the mounting mechanism 1 to move, and finally realizes the separation of the two protective shells 201 in opposite directions. When the pedal 303 is pressed down, the rack 304 will drive the gear 311 to rotate. At this time, the L-shaped rack 312 moves to the right, and under the connection of the connecting rod 313 and the rotating block 314, it pushes the lifting block 309 to rise along the lifting port 307. At this time, the pressure rod 310 rises along the lifting groove 308. When the two protective shells 201 are fully opened, the pressure rod 310 rises along the lifting groove 308 to the top, and the pedal 303 is released. The pedal 303 remains pressed down, and the protective shell 201 is in the open state. Under the push of the spring 319, the tilting push block 317 is reset. When the maintenance is completed and the two protective shells 201 need to be closed, step on the pressure rod 310 to make it move down along the lifting groove 308 and drive the lifting block 309 down along the lifting opening 307. Then, under the push of the connecting rod 313 and the rotating block 314, the L-shaped rack 312 is controlled to move to the left, and the gear 311 is rotated in the opposite direction, so that the rack 304 moves to the right to reset. Then, the pedal 303 is lifted up again by the connecting rod 305, so that it can be used to control the opening and closing of the protective shell 201 next time. During the descent of the pressure rod 310, the L-shaped locking block 318 will be pressed to the left by the inclined surface of the top of the L-shaped locking block 318. This makes it easier for the pressure rod 310 to descend to the bottom of the lifting groove 308. Then, the spring 319 will push the inclined push block 317 to the right to reset, so that the L-shaped locking block 318 will re-lock onto the outside of the pressure rod 310, restricting its rise and thus ensuring the stability of the two protective shells 201 after they are closed.

[0020] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
