Description

Technical Field

[0001] The utility model relates to the technical field of diesel generator sets, and particularly relates to a diesel generator set with automatic speed regulation. Background Technique

[0002] A diesel generator is a small power generation device, which is a power machine that uses diesel and other fuels and uses a diesel engine as a prime mover to drive a generator to generate electricity. During the power generation process of the diesel generator, in order to ensure the stability of the voltage and make full use of the fuel, it is necessary to instantaneously adjust the rotational speed of the rotor according to the change of the load. The automatic adjustment of the rotor speed mainly depends on the cooperation of a speed sensor, an electronic governor, and a control algorithm. Among them, the speed sensor is used to sense the change of the load of the generator set, and its accuracy plays a crucial role in the accuracy of the automatic speed regulation. Therefore, it is necessary to regularly check and calibrate the speed sensor.

[0003] At present, the shell of a diesel generator set is generally fixedly connected by screws, and the connection is firm and reliable. However, in the case where it is necessary to frequently calibrate and check the position of the speed sensor, the disassembly and assembly are very troublesome, and the screws are easy to lose. After being removed, they need to be stored, which increases the invisible workload during the calibration of the speed sensor.

[0004] Therefore, a diesel generator set with automatic speed regulation is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a diesel generator set with automatic speed regulation to solve the problems mentioned in the above background technique.

[0006] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0007] A diesel generator set with automatic speed regulation includes a base platform. On the top surface of the base platform, a radiator water tank body, a diesel engine, a flywheel box, and a generator body are fixedly installed in sequence from left to right. The radiator water tank body, the diesel engine, the flywheel box, and the generator body are connected to each other. A crankshaft is rotatably installed between the diesel engine, the flywheel box, and the generator body. A flywheel is fixedly installed on the surface of the crankshaft. The flywheel is arranged in the flywheel box. A corner cover is arranged on the front side of the upper part of the flywheel box. A sliding plug fixing component for fixing the corner cover is arranged on the surfaces of the flywheel box and the corner cover. A self-locking driving component and a distance adjusting mechanism are arranged on the top wall of the corner cover. The self-locking driving component is used to drive the distance adjusting mechanism. An installation pipe is fixedly installed on the surface of the moving part of the distance adjusting mechanism. One end of the installation pipe close to the flywheel is threadedly installed with a speed sensor. A wire threading component is arranged on the top wall of the corner cover.

[0008] Further, the sliding and plugging fixing component includes a plug block, a slide rail, a fixing plate and a bolt. The plug block is fixedly installed at the lower part of the left and right side surfaces of the corner cover. The slide rail is fixedly installed on the left and right side surfaces of the flywheel box. The plug block is slidably inserted into the slide rail. The number of the fixing plates is two, and they are respectively fixedly installed on the surfaces of the flywheel box and the corner cover. The two fixing plates are arranged in a relative and fitting manner before and after. The bolt is threadedly connected to the surfaces of the two fixing plates.

[0009] Further, the self-locking driving component includes a part cavity, which is opened inside the top wall of the corner cover. A worm is rotatably installed on the inner wall surface of the part cavity. The worm penetrates through the top surface of the corner cover and is rotatably arranged. A knob is fixedly installed on the top surface of the worm. A worm gear is meshed on the surface of the worm. A rotating rod is fixedly installed on the surface of the worm gear. The rotating rod is rotatably installed on the front and rear side surfaces of the inner wall of the part cavity. A partial structure of the distance adjusting mechanism is fixedly connected to the surface of the end of the rotating rod.

[0010] Further, the distance adjusting mechanism includes a chute, which is opened on the top surface of the inner wall of the corner cover. A threaded rod is rotatably installed between the front and rear side surfaces of the inner wall of the chute. The threaded rod is fixedly connected to the surface of the rotating rod. A moving plate is slidably installed on the inner wall surface of the chute. The moving plate is threadedly installed on the surface of the threaded rod. A fixing ring is fixedly installed on the surface of the moving plate. The installation pipe is fixedly installed on the surface of the fixing ring.

[0011] Further, the installation pipe is in an L-shaped structure. The port of the horizontal part of the installation pipe faces the flywheel. The rotational speed sensor is threadedly installed in the port of the horizontal part of the installation pipe. The rotational speed sensor is arranged flush with the center point of the flywheel.

[0012] Further, the wire threading component includes a wire threading hole, which is opened on the top wall of the corner cover. A housing is fixedly installed on the inner wall surface of the wire threading hole. A rubber layer is fixedly installed between the upper and lower sides of the inner side surface of the housing.

[0013] The beneficial effects of the present utility model are as follows:

[0014] When it is necessary to check the accuracy of the rotational speed sensor, it is not necessary to remove the corner cover. The cable of the rotational speed sensor passed out through the wire threading component can be directly connected to the detection device. When it is found that the accuracy of the rotational speed sensor is poor, the distance adjusting mechanism is directly driven by the self-locking driving component. The distance adjusting mechanism drives the installation pipe and the rotational speed sensor to move forward and backward synchronously, adjusts the distance between the rotational speed sensor and the flywheel, and at the same time, cooperates with the monitoring of the detection device until the measurement result of the rotational speed sensor is accurate. It is not necessary to remove the corner cover to complete the inspection and calibration of the rotational speed sensor, effectively eliminating the disassembly work during the inspection and calibration of the rotational speed sensor, and being safer, faster and more convenient.

[0026] Such as Figures 1 to 5As shown in the figure, a diesel generator set with automatic speed regulation includes a base 1. On the top surface of the base 1, a radiator water tank body 7, a diesel engine 2, a flywheel box 3, and a generator body 4 are fixedly installed in sequence from left to right. The radiator water tank body 7, the diesel engine 2, the flywheel box 3, and the generator body 4 are connected to each other. A crankshaft 5 is rotatably installed between the diesel engine 2, the flywheel box 3, and the generator body 4. A flywheel 6 is fixedly installed on the surface of the crankshaft 5. The flywheel 6 is arranged inside the flywheel box 3. A horn cover 8 is provided on the front side of the upper part of the flywheel box 3. A sliding plug fixing component 9 for fixing the horn cover 8 is provided on the surfaces of the flywheel box 3 and the horn cover 8. A self-locking driving component 10 and a distance adjusting mechanism 11 are provided on the top wall of the horn cover 8. The self-locking driving component 10 is used to drive the distance adjusting mechanism 11. An installation pipe 12 is fixedly installed on the surface of the moving part of the distance adjusting mechanism 11. A speed sensor 13 is threadedly installed at one end of the installation pipe 12 close to the flywheel 6. A wire threading component 14 is provided on the top wall of the horn cover 8. More specifically, when it is necessary to check the accuracy of the speed sensor 13, there is no need to remove the horn cover 8. Just connect the cable of the speed sensor 13 passed through the wire threading component 14 to the detection device directly. When it is found that the accuracy of the speed sensor 13 is poor, directly drive the distance adjusting mechanism 11 through the self-locking driving component 10. Drive the installation pipe 12 and the speed sensor 13 to move forward and backward synchronously through the distance adjusting mechanism 11, adjust the distance between the speed sensor 13 and the flywheel 6, and at the same time cooperate with the monitoring of the detection device until the measurement result of the speed sensor 13 is accurate. The inspection and calibration of the speed sensor 13 can be completed without removing the horn cover 8, which is safer, faster, and more convenient, effectively eliminating the disassembly work when inspecting and calibrating the speed sensor 13. When it is necessary to replace the speed sensor 13, the horn cover 8 can be quickly removed by disassembling the sliding plug fixing component 9, and the speed sensor 13 can be replaced.

[0027] The sliding plug fixing component 9 includes a plug block 901, a slide rail 902, a fixing plate 903, and a bolt 904. The plug block 901 is fixedly installed at the lower part of the left and right sides of the horn cover 8. The slide rail 902 is fixedly installed on the left and right sides of the flywheel box 3. The plug block 901 is slidably inserted into the slide rail 902. The number of fixing plates 903 is two and they are respectively fixedly installed on the surfaces of the flywheel box 3 and the horn cover 8. The two fixing plates 903 are arranged in a relative and fitting manner front and back. The bolt 904 is threadedly connected to the surfaces of the two fixing plates 903. Specifically, when it is necessary to remove the horn cover 8 to replace the speed sensor 13, rotate the bolt 904 to make the bolt 904 disengage from the surface of the fixing plate 903, and then pull the horn cover 8 forward. When the plug block 901 completely slips out of the slide rail 902, the disassembly of the horn cover 8 is completed, which is convenient and fast. And through the cooperation of the plug block 901 and the slide rail 902, the connection between the horn cover 8 and the flywheel box 3 is made more tightly and reliably.

[0028] The self-locking drive assembly 10 includes a part cavity 101 which is opened inside the top wall of the corner cover 8. A worm 102 is rotatably installed on the inner wall surface of the part cavity 101. The worm 102 penetrates through the top surface of the corner cover 8 and is rotatably arranged. A knob 103 is fixedly installed on the top surface of the worm 102. A worm gear 104 is meshed on the surface of the worm 102. A rotating rod 105 is fixedly installed on the surface of the worm gear 104. The rotating rod 105 is rotatably installed on the front and rear side surfaces of the inner wall of the part cavity 101. A partial structure of the distance adjustment mechanism 11 is fixedly connected to the surface of the end of the rotating rod 105. Specifically, rotating the knob 103 drives the worm 102 to rotate, causing the worm gear 104 meshed on the surface of the worm 102 to rotate, and then driving the rotating rod 105 to rotate. Finally, it realizes the drive of a partial structure of the distance adjustment mechanism 11, drives the rotation speed sensor 13 to move back and forth, adjusts the distance between the rotation speed sensor 13 and the flywheel 6, and uses the cooperation of the worm 102 and the worm gear 104 to achieve self-locking and avoid the misoperation of the rotating rod 105.

[0029] The distance adjustment mechanism 11 includes a sliding groove 111 which is opened on the top surface of the inner wall of the corner cover 8. A threaded rod 112 is rotatably installed between the front and rear side surfaces of the inner wall of the sliding groove 111. The threaded rod 112 is fixedly connected to the surface of the rotating rod 105. A moving plate 113 is slidably installed on the inner wall surface of the sliding groove 111. The moving plate 113 is threadedly installed on the surface of the threaded rod 112. A fixing ring 114 is fixedly installed on the surface of the moving plate 113. The installation pipe 12 is fixedly installed on the surface of the fixing ring 114. Specifically, the rotation of the rotating rod 105 drives the threaded rod 112 to rotate, causing the moving plate 113 which is threadedly installed on the surface of the threaded rod 112 and slidably installed on the inner wall surface of the sliding groove 111 to move back and forth, making the fixing ring 114 and the installation pipe 12 fixed by the fixing ring 114 move back and forth, and finally driving the rotation speed sensor 13 threadedly installed on the surface of the installation pipe 12 to move back and forth.

[0030] The installation pipe 12 is of an L-shaped structure. The port of the horizontal part of the installation pipe 12 faces the flywheel 6. The rotation speed sensor 13 is threadedly installed in the port of the horizontal part of the installation pipe 12. The rotation speed sensor 13 is arranged flush with the center point of the flywheel 6. Specifically, by the rotation speed sensor 13 sensing the change in the distance from the side of the flywheel 6 during the rotation of the flywheel 6, the monitoring of the rotation speed is realized. While the installation pipe 12 is used for installing and fixing the rotation speed sensor 13, it guides the cable of the rotation speed sensor 13, so that the cable of the rotation speed sensor 13 passes through the threading assembly 14 and moves out of the top of the corner cover 8.

[0031] The wire threading assembly 14 includes a wire threading hole 141 which is formed in the top wall of the corner cover 8. A housing 142 is fixedly installed on the inner wall surface of the wire threading hole 141. A rubber layer 143 is fixedly installed between the upper and lower sides of the inner side surface of the housing 142. A spring ring 144 is placed inside the spring ring 144. Specifically, the cable of the rotational speed sensor 13 passes through the middle of the rubber layer 143. By utilizing the elasticity of the spring ring 144, the rubber layer 143 is closely attached to the surface of the cable, thereby effectively preventing external dust from entering the flywheel box 3.

[0032] In summary: When it is necessary to check the accuracy of the rotational speed sensor 13, directly connect the cable of the rotational speed sensor 13 passing through the wire threading assembly 14 to the detection device. When it is found that the accuracy of the rotational speed sensor 13 is poor, directly drive the distance adjustment mechanism 11 through the self-locking drive assembly 10. Drive the mounting tube 12 and the rotational speed sensor 13 to move synchronously back and forth through the distance adjustment mechanism 11, adjust the distance between the rotational speed sensor 13 and the flywheel 6, and at the same time cooperate with the monitoring of the detection device until the measurement result of the rotational speed sensor 13 is accurate. It is possible to complete the inspection and calibration of the rotational speed sensor 13 without disassembling the corner cover 8, effectively eliminating the disassembly work when inspecting and calibrating the rotational speed sensor 13, which is safer, faster and more convenient.
