Description

Technical Field

[0001] The invention relates to the technical field of generators, in particular to a generator with a built-in water-cooled silencer. Background Art

[0002] A generator refers to a mechanical device that converts mechanical energy into electrical energy. It is driven by a turbine, a steam turbine, a diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator, which then converts it into electrical energy. The generator set in the prior art drives the central axis of the generator to rotate through an internal combustion engine, and then the generator works to generate electricity. The water-cooled generator will be equipped with an independent water-cooled silencer, which continuously delivers cold water to the generator. The cold water flows on the surface of the generator, absorbs heat in the generator, and finally becomes a flow of water at normal temperature and flows back into the water-cooled silencer for cooling. If the utilization rate of the cold water flow in the whole process can be improved, the energy-saving and emission reduction performance of the entire generator can be improved. For this reason, the present invention provides a generator with a built-in water-cooled silencer. Summary of the invention

[0003] The object of the present invention is to provide a generator with a built-in water-cooled silencer to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a generator with a built-in water-cooled silencer, comprising a generator box, a motor, an internal combustion engine for driving the motor to rotate and generate electricity, and a water-cooled silencer for water-cooling the motor, a first tube and a second tube are fixed to the outside of the motor, one end of the first tube is connected to a water outlet pipe on the water-cooled silencer, and one end of the second tube is connected to a recovery water pipe on the water-cooled silencer, a water-cooling cover is embedded in the outer shell of the motor, the water-cooling cover comprises a diffuser long flat tube fixedly connected to the other end of the first tube, a converger long flat tube fixedly connected to the other end of the second tube, a row of C-shaped flat tubes fixedly connected between the diffuser long flat tube and the converger long flat tube, a C-shaped temperature measuring stand for sensing the temperature on the C-shaped flat tube, a double-control valve transmission-connected to one end of the C-shaped temperature measuring stand, and a long worm transmission-connected to the row of double-control valves.

[0005] The double-control valve includes a gate arc plate with one end slidingly inserted into the water inlet port on the C-shaped flat tube, a row of interception columns fixed in the C-shaped flat tube, and a double-control tool for controlling the switch of the gate arc plate. The gate arc plate is vertically distributed in a long arc plate cavity opened inside the diffuser long flat tube, and the other end of the gate arc plate slides through a plate hole opened on the diffuser long flat tube. The long worm is connected to the double-control tool in transmission, and the double-control tool is in contact with the end of the gate arc plate outside the diffuser long flat tube for transmission.

[0006] The double-control valve further includes a return spring piece fixed outside the long and flat heat dissipation pipe, and one end of the return spring piece elastically supports a convex block arranged on the door arc plate.

[0007] The door arc plate is in the shape of an arc plate, and a main circuit plate hole vertically penetrating is provided in the door arc plate. And a row of branch circuit plate holes are provided in the door arc plate on one side of the main circuit plate hole. The intercepting column is slidably inserted into the branch circuit plate hole through the arc plate column arranged thereon.

[0008] The C-shaped temperature measuring frame includes heat conduction blocks evenly arranged around the motor housing, a C-shaped pressure column supported by all the heat conduction blocks, and a deformation rod vertically contacting the C-shaped pressure column. One end of the C-shaped pressure column is in transmission connection with the double-control tool.

[0009] The heat conduction blocks are fixed on the C-shaped flat pipe. One end of the deformable rod that can expand due to heat is inserted into a cylindrical groove provided on the heat conduction block. The other end of the deformable rod contacts a beveled convex plate arranged on the C-shaped pressure column. The C-shaped pressure column is arranged on one side of the C-shaped flat pipe in a ring shape.

[0010] The double-control tool includes a first plate frame fixed on the long and flat heat dissipation pipe, a split shaft supported on the first plate frame, and a main control body vertically fixed at one end of the split shaft. The split shaft is movably sleeved in a circular hole provided on the first plate frame. The long worm is movably sleeved in an inner hole of a cylinder arranged on the first plate frame. The other end of the split shaft is in meshing transmission connection with the helical teeth on the long worm through a fixed spur gear.

[0011] The double-control tool further includes a temperature control body distributed in parallel with the main control body, a horizontal shaft established in transmission with the C-shaped pressure column, and an extension device in transmission connection between the horizontal shaft and the temperature control body. The main control body and the temperature control body have the same shape, and both include a disc body and a convex plate fixed at the edge of one end of the disc body. And the convex plates of the main control body and the temperature control body drive the door arc plate to move by pushing an intercepting block arranged on the door arc plate. The main control body toggles the intercepting block on the door arc plate once every time it rotates one circle. And the main control bodies in a row of double-control tools take turns to toggle the contacted door arc plate. The temperature control body drives the door arc plate through swinging.

[0012] The extension device includes a limit shaft, a swing rod and a fixed shaft. One end of the limit shaft is vertically fixed in the middle of the disc body of the temperature control body. The other end of the limit shaft is in meshing transmission connection with an arc-shaped rack arranged at one end of the swing rod through a set of enlarged gears. The other end of the swing rod is fixedly connected with one end of the fixed shaft. The other end of the fixed shaft is in meshing transmission connection with a bevel gear fixed at one end of the horizontal shaft through a fixed bevel gear. The other end of the horizontal shaft is in meshing transmission connection with a row of tooth grooves arranged in an arc shape on the C-shaped pressure column through a set of lapping gears.

[0013] The extension device further includes a second plate frame. One end of the second plate frame is fixed on the long and flat heat dissipation pipe. The limit shaft, the fixed shaft and the horizontal shaft are respectively movably sleeved in three through holes provided on the second plate frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention uses a long worm to quickly cool the interior of the motor. The alternating water supply mechanism in the long worm can effectively improve the utilization rate of the cold water flow. The cold water flowing in the C-shaped flat tube fully absorbs heat and then is discharged. In addition, if the motor accidentally operates and causes excessive local heat generation, which is detected by the external C-shaped temperature measuring frame, the corresponding C-shaped flat tube will be automatically triggered to continuously flow water inside, without waiting for alternating water supply. In this way, the local heat can be quickly absorbed by the continuously flowing cold water flow.

[0015] 2. The traditional technology uses the common water supply and cooling method for all cooling branch paths. If the temperature of a single branch path is high and accelerated water supply is required, the other normal temperature area paths do not need accelerated water supply for cooling. In this way, centralized accelerated water supply for all branch paths will cause waste problems. The present invention can avoid the waste problems caused by centralized accelerated water supply for all paths by automatically selecting the water supply mode.

[0016] 3. The present invention drives the door arc plate through the rotation of the main control body and the swing of the temperature control body, thereby opening the port channel of the C-shaped flat tube. The swing of the temperature control body ultimately caused by local overheating further pushes the door arc plate to move, and the port channel of the C-shaped flat tube remains open. At this time, during one rotation of the main control body, the main control body can still toggle to the door arc plate, but the door arc plate will not completely reset after toggling because the convex plate of the temperature control body intercepts and affects the reset of the door arc plate. In this way, the alternating water supply mechanism and the water supply mechanism caused by high heat do not affect each other. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the technical solutions in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 13 The present invention provides a technical solution: a generator with a built-in water-cooled silencer, comprising a generator box 1, a motor 2, an internal combustion engine driving the motor 2 to rotate and generate electricity, and a water-cooled silencer 12 for water-cooling the motor 2, a first pipe 10 and a second pipe 11 are fixed to the outside of the motor 2, one end of the first pipe 10 is connected to the water outlet pipe on the water-cooled silencer 12, and one end of the second pipe 11 is connected to the recovery water pipe on the water-cooled silencer 12, a water-cooling cover 3 is embedded in the outer shell of the motor 2, the water-cooling cover 3 includes a diffuser long flat tube 5 fixedly connected to the other end of the first tube 10, a converging long flat tube 6 fixedly connected to the other end of the second tube 11, a row of C-shaped flat tubes 7 fixedly connected between the diffuser long flat tube 5 and the converging long flat tube 6, a C-shaped temperature measuring frame 8 for sensing the temperature on the C-shaped flat tube 7, a double-control valve 9 driven and connected to one end of the C-shaped temperature measuring frame 8, and a long worm 4 driven and connected to the row of double-control valves 9, with reference to Figure 4One end of the long worm 4 establishes transmission with the central shaft on the motor 2 through the speed reduction transmission mechanism in the prior art. When the central shaft of the motor 2 rotates, the motor 2 works to generate electricity, and at the same time causes the long worm 4 to rotate slowly, so that the water cooling hood 3 performs distributed cold water cooling work.

[0033] refer to Figure 5 It is understood that the double control valve 9 includes a gate arc plate 14 with one end slidingly inserted into the water inlet port on the C-type flat tube 7, a row of interception columns 13 fixed in the C-type flat tube 7, and a double control device 15 for controlling the switch of the gate arc plate 14, the gate arc plate 14 is vertically distributed in the long arc plate cavity opened inside the diffuser long flat tube 5, and the other end of the gate arc plate 14 slides through the plate hole opened on the diffuser long flat tube 5, the long worm 4 and the double control device 15 are transmission connected, and the double control device 15 and the end of the gate arc plate 14 outside the diffuser long flat tube 5 are in contact with each other for transmission.

[0034] The double control valve 9 further includes a return spring piece 16 fixed to the outside of the diffuser long flat tube 5 , and one end of the return spring piece 16 elastically supports a convex block provided on the gate arc plate 14 .

[0035] refer to Figure 10 It is understood that the door arc plate 14 is shaped like an arc plate, and a vertically penetrating main plate hole 141 is provided in the door arc plate 14, and a row of branch plate holes 142 are provided in the door arc plate 14 on one side of the main plate hole 141. The intercepting column 13 is slidably inserted into the branch plate hole 142 by setting an arc plate column. The intercepting column 13 is pulled out from the branch plate hole 142, and the cold water flow in the scattered long flat tube 5 is injected into the main plate hole 141, and then injected into the C-type flat tube 7 through the branch plate hole 142. The C-type flat tube 7 is a sensitive heat-conducting material in the prior art. The heat dissipated in the motor 2 is transferred to the C-type flat tube 7 and then absorbed and offset. In this way, the heat inside the motor 2 is quickly dissipated and cooled.

[0036] refer to Figure 6 It is understood that the C-type temperature measuring frame 8 includes a heat-conducting block 17 evenly arranged in a ring in the outer shell of the motor 2, a C-type pressure column 19 supported by all the heat-conducting blocks 17, and a deformation rod 18 vertically contacting the C-type pressure column 19, and one end of the C-type pressure column 19 is transmission-connected to the double control device 15.

[0037] The heat-conducting block 17 is fixed on the C-shaped flat tube 7. One end of a deformable rod 18 that can expand due to heat is inserted into a cylindrical groove provided on the heat-conducting block 17. The other end of the deformable rod 18 contacts a convex plate with an inclined surface provided on a C-shaped pressure column 19. The C-shaped pressure column 19 is arranged on one side of the C-shaped flat tube 7.

[0038] The dual control device 15 includes a first plate frame 25 fixed on the diffuser long flat tube 5, a sub-shaft 24 supported on the first plate frame 25, and a main control body 22 with one end of the sub-shaft 24 vertically fixed. The sub-shaft 24 is movably sleeved in a circular hole opened on the first plate frame 25, and the long worm 4 is movably sleeved in the inner hole of the cylinder set on the first plate frame 25. The other end of the sub-shaft 24 is connected to the helical teeth on the long worm 4 through a fixed sub-gear 241.

[0039] The dual control device 15 also includes a temperature control body 21 distributed in parallel with the main control body 22, a transverse shaft 23 that establishes transmission with the C-shaped pressure column 19, and a range extender 20 that is transmission-connected between the transverse shaft 23 and the temperature control body 21. The main control body 22 and the temperature control body 21 have the same shape, both including a disc and a convex plate fixed at one end edge of the disc, and the convex plate of the main control body 22 and the convex plate of the temperature control body 21 both drive the door arc plate 14 to move by pushing the interception block provided on the door arc plate 14. The main control body 22 moves the interception block on the door arc plate 14 once every rotation, and the main control bodies 22 in a row of dual control devices 15 move the contacted door arc plate 14 in turn, and the temperature control body 21 drives the door arc plate 14 by swinging. Figure 13 and Figure 9 It is understood that the positions of the convex plates on a row of main control bodies 22 are different. In this way, when all the main control bodies 22 rotate synchronously, the timing of the main control bodies 22 to move the door arc plates 14 is different. A row of door arc plates 14 are moved in turn, and the water inlet ports of a row of C-shaped flat tubes 7 are opened in turn.

[0040] The range extender 20 includes a limit shaft 26, a rocker arm 28 and a fixed shaft 29. One end of the limit shaft 26 is vertically fixed to the middle of the disk of the temperature control body 21. The other end of the limit shaft 26 is meshed and connected to the arc-shaped rack set at one end of the rocker arm 28 through an amplifying gear 261. The other end of the rocker arm 28 is fixedly connected to one end of the fixed shaft 29. The other end of the fixed shaft 29 is meshed and connected to the bevel gear fixed at one end of the transverse shaft 23 through a fixed bevel gear. The other end of the transverse shaft 23 is meshed and connected to a row of teeth arranged in an arc shape on the C-shaped pressure column 19 through a lap gear 231.

[0041] The range extender 20 further includes a second plate frame 27 , one end of which is fixed on the diffuser long flat tube 5 , and the limit axis 26 , the fixed axis 29 and the transverse axis 23 are respectively movably sleeved in three through holes opened on the second plate frame 27 .

[0042] The water cooling cover 3 has two mechanisms for conveying cold water flow. One is that the long worm 4 rotates, and through subsequent transmission, all the main control bodies 22 are caused to rotate synchronously. The timing of each main control body 22 to move the gate arc plate 14 is different, so that a row of gate arc plates 14 move in turn, and the gate arc plate 14 is partially withdrawn from the C-shaped flat tube 7. The intercepting column 13 no longer blocks the gate arc plate 14, and then the cold water flow in the scattered long flat tube 5 is injected into the C-shaped flat tube 7. The diversion water in a row of C-shaped flat tubes 7 is carried out in turn. When water flows in a single C-shaped flat tube 7, the water flow in other C-shaped flat tubes 7 stops flowing, so that the water flow stops. The flowing cold water flow can fully absorb the heat dissipated from the motor 2. Compared with the traditional technology, the cold water flow continuously flows on the surface of the motor 2. The present invention uses intermittent flow, which can ensure that the cold water flow fully absorbs the heat. The traditional continuous water circulation method has the problem that the cold water is discharged without being fully heated up, which is wasteful. The cold water flow supply mode of the present invention can improve the energy saving of the entire generator set. The transmission process between the long worm 4 and the main control body 22 is: the long worm 4 rotates to drive the sub-gear 241, and then drives the main control body 22 to rotate through the sub-shaft 24.

[0043] The present invention also has an automatic water supply adjustment mechanism. If the temperature at the location of the C-type flat tube 7 is too high, there is no need to wait for water to be delivered in turn. The deformable rod 18 is a material that can expand and contract with heat in the prior art. The overheated temperature causes the deformable rod 18 to expand and stretch. The deformable rod 18 pushes the C-type pressure column 19, and then the C-type pressure column 19 rotates to drive the overlapping gear 231 at one end to rotate, and then the fixed axis 29 is transmitted through the horizontal axis 23, and then the swing rod 28 swings to drive the limit axis 26 to rotate, and then the temperature control body 21 rotates slightly, and the convex plate on the temperature control body 21 pushes the door arc plate 14. After the door arc plate 14 moves, the water inlet port of the C-type flat tube 7 is opened, and then water continues to flow in the C-type flat tube 7, and the cold water flow quickly absorbs the nearby heat. The automatic water supply mechanism caused by high temperature and the rotating water supply mechanism are not contradictory, and can occur at the same time, so that the inside of the motor 2 can be safely and quickly cooled.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
