Description

Technical Field

[0001] This utility model relates to the field of diesel generator technology, and in particular to a frequency stabilization control device for a diesel generator. Background Technology

[0002] A diesel generator is a small power generation device, referring to a power machine that uses diesel fuel and a diesel engine as the prime mover to drive the generator to generate electricity. The generator controller is the core of the generator, equivalent to the human brain. The standard definition is: a master control device that controls the generator's starting, speed regulation, braking and reversing by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to a predetermined sequence. In the existing technology, it is not convenient to detect the diesel engine speed in real time and adjust the diesel fuel supply according to the speed, which is not conducive to maintaining the speed stability. As a result, the current value of the generator input varies greatly, which is not conducive to the generator generating electricity better. In response to the above problems, the document with application number: 202310082277.2 discloses a speed-stable diesel generator, which includes a housing, a rotating ring, a diesel engine and a generator. The diesel engine and the generator are respectively mounted on the bottom two ends of the housing through mounting bases. The oil tank and the PLC controller are respectively fixedly connected to the two ends of the inner wall of the housing through bolts. The oil outlet of the oil tank is connected to the oil inlet of the diesel engine through an oil supply pipe. An electromagnetic regulating valve is provided on the oil supply pipe. A speed measuring instrument is mounted on one end of the top of the diesel engine through a mounting bracket. The measuring end of the speed measuring instrument is connected to a measuring roller. However, a thorough reading of the aforementioned patent documents reveals the following shortcomings: In use, the controller on the diesel generator is fixed to the generator with bolts. However, fixing the controller with bolts complicates the installation and disassembly process, increases time and labor costs, and requires tools to operate, thus significantly reducing the ease of maintenance for staff. There is room for improvement.

[0003] Therefore, this utility model provides a frequency stabilization control device for diesel generators to solve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention provides a frequency stabilization control device for a diesel generator, comprising: a diesel generator body, wherein the diesel generator body includes a diesel generator housing, a controller body, and a fixing mechanism; The diesel generator housing has an installation groove, a fixed frame is slidably connected in the installation groove, the controller body is fixedly installed in the fixed frame, two fixing mechanisms are provided on one side of the fixed frame, and two slots are provided on the diesel generator housing, with the two fixing mechanisms respectively connected to the two slots. The fixing mechanism includes a connecting rod, a limiting plate, a spring, a collar, and a push rod.

Through the cooperative design of the diesel generator housing, the fixing frame, the fixing mechanism, and the moving plate, the controller body can be quickly disassembled and installed without the use of tools, thus improving convenience.

[0005] Preferably, the connecting rod has four storage slots, and each of the four storage slots has a limiting plate welded inside. During the process of inserting the connecting rod into the corresponding slot, the four limiting plates on the connecting rod interact with the diesel generator housing. Since the four limiting plates are elastic, they deform and move into the four storage slots respectively. The four limiting plates engage with the corresponding slots. Through the interaction between the four limiting plates and the slots, the connecting rod is fixed and limited.

[0006] Preferably, each of the four storage slots is fixedly installed with a spring, and one end of each of the four springs is fixedly connected to the four limiting plates. The elastic potential energy of the four springs causes the four limiting plates to return to their original state.

At the same time, the moving plate drives the four push rods to slide a certain distance to the right synchronously on the diesel generator housing. At this time, the four push rods respectively push the corresponding collar to slide to the rightmost end in the corresponding slot. During this process, the connecting rod corresponding to the collar slides to the right and acts with the four limiting plates, causing the four limiting plates to disengage from their slots and move into the four receiving slots respectively, thereby achieving the purpose of releasing the limiting of the connecting rod.

[0008] Preferably, the collar has a through hole that is adapted to the connecting rod, so that one end of the connecting rod can pass through the collar. The collar is adapted to the slot, so that the collar can slide in the corresponding slot. All four limiting plates are elastic, so that the four limiting plates can return to their original shape after deformation. The four storage slots are adapted to the four limiting plates respectively, so that the four limiting plates can be stored.

[0009] Preferably, a sliding groove is provided on the diesel generator housing, and a movable plate is slidably connected in the sliding groove. One end of each of the four push rods passes through the diesel generator housing and is fixedly connected to the movable plate. The movable plate facilitates the synchronous pushing of the four push rods. A spring is fixedly installed in the sliding groove, and one end of the spring is fixedly connected to the movable plate. The elastic potential energy of the spring causes the movable plate to return to its original shape.

[0010] Preferably, the diesel generator body further includes a power generation device, and the controller body is connected to the power generation device. The power generation device can generate electricity, and the controller body can perform frequency conversion regulation on the power generation device.

The fixing mechanism includes a connecting rod 4, a limiting plate 5, a spring 6, a collar 7, and a push rod 8. Two connecting rods 4 are fixedly connected to one side of the fixing frame 2 and are respectively inserted into two slots 11. Through the cooperative design of the diesel generator housing 1, the fixing frame 2, the fixing mechanism, and the moving plate 9, the controller body 3 can be quickly disassembled and installed without the use of tools, which improves convenience.

[0016] In this method, the connecting rod 4 is provided with four storage slots 12, and each of the four storage slots 12 is welded with a limiting plate 5. When the connecting rod 4 is inserted into the corresponding slot 11, the four limiting plates 5 on the connecting rod 4 interact with the diesel generator housing 1. Since the four limiting plates 5 are elastic, they deform and move into the four storage slots 12 respectively. The four limiting plates 5 are engaged with the corresponding slots 11. Through the interaction between the four limiting plates 5 and the slots 11, the purpose of limiting and fixing the connecting rod 4 is achieved.

[0017] In this method, springs 6 are fixedly installed in each of the four storage slots 12. One end of each spring 6 is fixedly connected to one of the four limiting plates 5. The elastic potential energy of the four springs 6 causes the four limiting plates 5 to return to their original state.

[0018] In this method, a collar 7 is slidably sleeved on the connecting rod 4. The collar 7 is slidably connected to the corresponding slot 11. Two push rods 8 are fixedly connected to one side of the collar 7. Both push rods 8 are slidably connected to the diesel generator housing 1. By pushing the moving plate 9, the moving plate 9 slides to the right a certain distance in the sliding groove 1 on the diesel generator housing 1, and the spring 2 10 is compressed. At the same time, the moving plate 9 drives the four push rods 8 to slide to the right a certain distance on the diesel generator housing 1. At this time, the four push rods 8 push the corresponding collar 7 to slide to the rightmost end in the corresponding slot 11. During this process, the connecting rod 4 corresponding to the collar 7 slides to the right and acts with the four limiting plates 5, so that the four limiting plates 5 are disengaged from their slots 11 and move into the four receiving slots 12 respectively, thereby achieving the purpose of releasing the limiting of the connecting rod 4.

[0019] In this method, the collar 7 has a through hole that is adapted to the connecting rod 4, so that one end of the connecting rod 4 can pass through the collar 7. The collar 7 is adapted to the slot 11, so that the collar 7 can slide in the corresponding slot 11. The four limiting plates 5 are all elastic, so that the four limiting plates 5 can return to their original shape after deformation. The four storage slots 12 are adapted to the four limiting plates 5 respectively, so that the four limiting plates 5 can be stored.

[0020] In this method, a sliding groove is provided on the diesel generator housing 1, and a movable plate 9 is slidably connected in the sliding groove. One end of each of the four push rods 8 passes through the diesel generator housing 1 and is fixedly connected to the movable plate 9. The movable plate 9 facilitates the synchronous pushing of the four push rods 8. A second spring 10 is fixedly installed in the sliding groove, and one end of the second spring 10 is fixedly connected to the movable plate 9. The elastic potential energy of the second spring 10 causes the movable plate 9 to return to its original state.

[0021] In this method, the diesel generator body 14 also includes a power generation device. The controller body 3 is connected to the power generation device. The power generation device can generate electricity. The controller body 3 can perform frequency conversion regulation on the power generation device. The specific structure and working principle of the diesel generator body 14 and the power generation device can be referred to the document with application number 202310082277.2. This is prior art and will not be described in detail. The specific structure and working principle of the controller body 3 can be referred to the document with application number 200710124545.3. This is prior art and will not be described in detail.

[0022] The working principle of the frequency stabilization control device for a diesel generator provided by this utility model is as follows: In use, firstly, insert one end of the fixing frame 2 into the mounting groove 13 on the diesel generator housing 1. Then, push the fixing frame 2 to the left using the handle on the fixing frame 2, causing the two connecting rods 4 to respectively engage with the two slots 11 on the diesel generator housing 1. During the insertion of the connecting rods 4 into the corresponding slots 11, the four limiting plates 5 on the connecting rods 4 all act against the diesel generator housing 1. Since the four limiting plates 5 are elastic, they cause the four limiting plates 5 to... The deformation causes the four springs 6 to be compressed. Then, when the four limiting plates 5 correspond to their slots 11, the elastic potential energy of the four springs 6 and the elastic potential energy of the four limiting plates 5 themselves cause the four limiting plates 5 to return to their original shape and engage with their slots 11. At this time, through the interaction between the four limiting plates 5 and the slots 11, the connecting rod 4 is limited and fixed, thereby limiting and fixing the fixed frame 2, and thus achieving the effect of quick installation of the controller body 3. When it is necessary to disassemble the controller body 3, the moving plate 9 is pushed and slides to the right a certain distance in the sliding groove 1 on the diesel generator housing 1, and the spring 10 is compressed. At the same time, the moving plate 9 drives the four push rods 8 to slide to the right a certain distance on the diesel generator housing 1. At this time, the four push rods 8 push the corresponding collar 7 to slide to the rightmost end in the corresponding slot 11. During this process, the connecting rod 4 corresponding to the collar 7 slides to the right and acts with the four limiting plates 5, so that the four limiting plates 5 are disengaged from their slots 11 and move into the four storage slots 12 respectively, thereby achieving the purpose of releasing the limitation on the connecting rod 4. Then, the fixed frame 2 is pulled to the right by the handle on the fixed frame 2, so that the two connecting rods 4 are disengaged from the two slots 11 respectively. After that, the fixed frame 2 and the controller body 3 are taken out from the mounting slot 13, thereby achieving the effect of quick disassembly of the controller body 3.
