Technical Field

[0001] This utility model relates to the field of generator teaching and assessment technology, and in particular to a diesel generator set fault diagnosis and training and assessment device. Background Technology

[0002] In teaching, practical assessments, and skills certifications, faults need to be set up on generator sets for students to diagnose. This is usually done by damaging the generator's wiring, piping, or other components, which is time-consuming, labor-intensive, and can easily damage the equipment. Practical assessments, in particular, require setting up faults for each student, reducing testing efficiency.

[0003] Among existing patented technologies, such as Chinese patent CN219418346U authorized on 2023-07-25, a drive motor fault setting and measurement box is disclosed, which can be used to set faults and can be used with some fault setting modules to set and measure faults in drive motors, thus meeting the needs of teaching.

[0004] However, these existing patented technologies do not allow for pre-setting fault types. In practical assessments and other scenarios, faults still need to be set temporarily, which reduces the efficiency of the exam. Utility Model Content

[0005] The purpose of this utility model is to provide a diesel generator set fault diagnosis and training and assessment device, which can realize the rapid setting of different types of faults and improve the examination efficiency.

[0006] This utility model provides a diesel generator set fault diagnosis and training and assessment device, including a generator set and a control panel. The control panel is equipped with multiple fault control switches, which are connected to the generator set through wires to control the generator set to generate different types of faults.

[0007] Furthermore, the fault control switch includes a manual switch, and the manual part of the manual switch is located on the surface of the control panel.

[0008] Furthermore, a first label is provided on the surface of the control panel corresponding to the position of the manual switch, and the first label is used to display the name of the manual switch.

[0009] Furthermore, a second label is provided on the surface of the control panel corresponding to the position of the manual switch, and the second label is used to display the fault type controlled by the manual switch.

[0010] Furthermore, it also includes a remote control, the fault control switch including a remote control switch, and the remote control having buttons corresponding to different remote control switches.

[0011] Furthermore, the button is provided with a third label, which is used to display the name and / or fault type of the remote control switch.

[0012] Furthermore, the manual switch and the remote control switch are connected in series.

[0013] Furthermore, both the manual switch and the remote control switch are normally closed, and when they are opened, they cause a malfunction in the generator set.

[0014] Furthermore, it also includes a housing, the housing is provided with a terminal block, the control panel is fixed in the housing, and the lower part of the housing is provided with a cable entry and exit groove for the terminal block wiring.

[0032] Example 1

[0033] like Figures 1-9 As shown, this utility model provides a diesel generator set fault diagnosis and training and assessment device, including a generator set and a control panel 1. The control panel 1 is equipped with multiple fault control switches, which are connected to the generator set through wires to control the generator set to generate different types of faults.

[0034] Specifically, the two pins of the fault control switch are connected to wires. When connecting the wires to the unit's wires, because there are open wire lugs, the connection can be made at the terminal block without cutting or damaging the wires. Note that the wire numbers of the switch wires and the unit wires must be consistent. For example, if one wire of switch K01 is connected to the unit's wire, then the other wire of switch K01 should be connected to the other terminal of the wire on the terminal block. If the wire is the unit's throttle control valve line, since the control valve controls the unit's oil circuit switch and the amount of oil supplied, switch K01 controls the unit's oil circuit fault, and the fault will be marked as oil circuit fault below switch K01.

[0035] Similarly, this diesel generator set fault diagnosis and training / assessment device can control the generator set to have other different fault types through other fault control switches, realizing the preset generator fault types. This allows for the rapid setting of different types of faults for different trainees and examinees during teaching, practical assessments, or skills certification processes, saving fault setup time and improving examination efficiency. For specific fault types and setting methods, please refer to Part 5 of the following embodiment.

[0036] Example 2

[0037] The fault control switch includes a manual switch K, the manual part of which is located on the surface of the control panel 1. A first label 3 is located on the surface of the control panel 1 corresponding to the position of the manual switch K, and the first label 3 displays the name of the manual switch K. A second label 4 is located on the surface of the control panel 1 corresponding to the position of the manual switch K, and the second label 4 displays the fault type controlled by the manual switch K.

[0038] Specifically, the manual switch K can be a toggle switch, the lever of which is the manual part. The toggle switch body is fixed to the inside of the control panel 1 (hidden inside the control panel 1 and the housing 6). The lever protrudes from the hole on the control panel 1, so the switch state can be changed by moving the lever, opening the normally closed contact and setting the corresponding fault for the generator.

[0039] On the surface of control panel 1, above the lever of manual switch K, affix a label with the name of each manual switch K, such as K1, K2, K3, K4, K5, K6, K7, K8, K9, K10, K11, K12, to facilitate easy identification of different manual switches K.

[0040] On the surface of the control panel 1, below the lever of the manual switch K, a second label 4 is affixed to each manual switch K to identify the fault type, such as starter circuit fault, positive open circuit fault, negative open circuit fault, fuel indicator signal fault, excitation circuit fault, DC motor charging fault, oil pressure signal fault, water temperature indicator signal fault, busbar current signal fault, phase loss fault, speed signal fault, and oil circuit fault. These labels correspond one-to-one with the names on the first label 3 of the manual switch K, making it easy to distinguish and identify the fault types controlled by different manual switches K.

[0041] Example 3

[0042] It also includes a remote controller 2, and a fault control switch including a remote control switch J. The remote controller 2 has buttons corresponding to different remote control switches J. Each button has a third label 5, which displays the name and / or fault type of the remote control switch J. A manual switch K and a remote control switch J are connected in series. Both manual switch K and remote control switch J are normally closed; when open, they control the generator set to generate a fault.

[0043] Specifically, the remote control switch J is common in this field, and its structural principle will not be described in detail. Both the remote controller 2 and the remote control switch J have antennas for remote control. The remote control switch J is located inside the control panel 1 within the housing 6 (hidden inside the control panel 1 and the housing 6), and is connected in series with the manual switch K. Both the remote control switch J and the manual switch K are normally closed contacts, which open when controlled, setting a corresponding fault for the generator.

[0044] Set buttons for each remote control switch J on the remote control 2, and set a third label 5 on the button (sprayed) for example, fault 1, fault 2, fault 3, fault 4, fault 5, fault 6, fault 7, fault 8, fault 9, fault 10, fault 11, fault 12, so as to easily distinguish and identify different remote control switches J.

[0045] The third label 5 on the button of the remote control 2 has a corresponding serial number or description to the first label 3 of the manual switch K on the surface of the control panel 1, so that the remote control 2 and the manual switch K can set the corresponding faults for the generator respectively.

[0046] Example 4

[0047] It also includes a housing 6, which contains a terminal block 7. The control panel 1 is fixed inside the housing 6, and the lower part of the housing 6 has a cable entry and exit groove 8 for the terminal block 7 to run.

[0048] Specifically, the enclosure 6 protects the entire device. The control panel 1 is located inside the enclosure 6. Terminal blocks 7 and other components are arranged between the inside of the control panel 1 and the inside of the enclosure 6. Wires are connected and exited through the inlet / outlet cable tray 8 on the lower side of the enclosure 6. The enclosure 6 is equipped with a cover that can be opened or closed.

[0049] Example 5

[0050] The fault types include starting circuit fault, positive open circuit fault, negative open circuit fault, fuel indicator signal fault, excitation circuit fault, DC motor charging fault, oil pressure signal fault, water temperature indicator signal fault, busbar current signal fault, phase loss fault, speed signal fault, and oil circuit fault.

[0051] Specifically, this utility model provides a total of 12 fault control switches, which control the aforementioned common faults respectively. The manual switches K are sequentially labeled K01, K02, K03, K04, K05, K06, K07, K08, K09, K10, K11, K12, and the remote control switches J are sequentially labeled J01, J02, J03, J04, J05, J06, J07, J08, J09, J10, J11, J12. The corresponding sequence numbers represent the same fault type. For ease of understanding, the following detailed description uses the circuit numbers marked in the attached diagram.

[0064] The working method and principle of this utility model:

[0065] By setting multiple fault control switches on control panel 1, different fault control switches can be used to control the generator to generate different types of faults, realizing the preset generator fault types.
