Description

Technical Field

[0001] This utility model relates to the field of charger testing technology, specifically a testing device for a diesel generator charger. Background Technology

[0002] A generator charger is an instrument that can charge a generator. Before use, the charger needs to be tested, which requires a special testing device.

[0003] Existing testing equipment only has one or two sets of individual terminals, which limits the testing of chargers to a single load condition. This results in limited test results and makes it impossible to test under various different load conditions. Therefore, corresponding improvements are needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a testing device for a diesel generator charger to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a testing device for a diesel generator charger, comprising two sets of support frames, each set of support frames having two sets of steel frames installed inside, and the inner sides of the two sets of support frames being connected to the bottom side of a placement plate via angle steel at both ends, a test plate being installed at the top center of the placement plate, and several sets of ammeters being installed inside the test plate near the top, several sets of terminal blocks being installed at the bottom of the test plate, several sets of variable resistors being installed at the top of the placement plate near the inner side of the test plate, and a charger body being movably placed at the top of the placement plate near the outer side of the test plate.

[0006] Preferably, the number of the shelves is four sets, and the four sets of shelves are stacked at equal intervals.

[0007] Preferably, through holes are provided at both ends of the inner side of the test board inside the three sets of placement boards above, and vertical steel pipes are inserted into the through holes.

[0008] Preferably, the bottom ends of the two sets of vertical steel pipes are installed together with the top end of the shelf installed at the bottom.

[0009] Preferably, the ammeters and terminal blocks are arranged in a straight line and arrayed inside the test board.

[0010] Preferably, several sets of the variable resistors are arranged in a line and arrayed on the top of the shelf, with each vertical row having two sets of variable resistors.

[0011] Preferably, both sets of steel frames are inclined and form a V-shape.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By incorporating components such as a mounting plate, test plate, ammeter, terminal block group, variable resistor, vertical steel frame, and through holes, the existing testing devices can effectively solve the problem that the existing devices only have one or two sets of individual terminals, which limits the testing of chargers to a single load condition, resulting in limited test results and an inability to meet the requirements of testing under various different load conditions.

[0014] Users can place the charger on top of the shelf and then electrically connect it to a set of terminals via four sets of cables. Two sets of variable resistors can be used to change the resistance within the corresponding terminal groups. Since the voltage inside the charger is constant, the current changes, causing a change in the ammeter pointer. This allows for current and voltage testing of the charger. Each set of terminals has sixteen pins, each with a different resistance value, while the charger only has four sets of cables. This provides multiple, non-repetitive connection methods for the charger to be electrically connected to the terminal groups via the four sets of cables. This allows for voltage and current testing under various load conditions, ensuring the quality of the charger and preventing malfunctions during subsequent use. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] according to Figures 1-4 As shown, the system includes two sets of support frames 1, both of which are H-shaped. Each set of support frames 1 contains two sets of steel frames 11. The inner sides of both sets of support frames 1 are connected to the bottom of a shelf 13 near one end via angle steel 12. One side of the angle steel 12 is connected to the inner wall of one side of the support frame 1 via mounting bolts, while the other side is connected to the bottom of the shelf 13 via mounting bolts. Both sets of steel frames 11 are inclined and form a V-shape. This V-shape provides limiting support within the corresponding support frame 1, allowing for more stable placement of the two support frames 1. There are four sets of shelf 13, stacked equidistantly. A test plate 14 is installed near the center of the top of each shelf 13, and a test plate 14 is installed near the top of the test plate 14. The test plate 14 is equipped with several sets of ammeters 15. Several sets of terminal blocks 16 are installed at the bottom of the test plate 14. The ammeters 15 and terminal blocks 16 are arranged in a straight line and array inside the test plate 14. Several sets of variable resistors 17 are installed at the top of the shelf 13 near the inside of the test plate 14. The charger body 2 is movably placed at the top of the shelf 13 near the outside of the test plate 14. The variable resistors 17 are arranged in a straight line and array on the top of the shelf 13, with two sets of variable resistors 17 in each column. Through holes 19 are opened at both ends of the inner side of the test plate 14 inside the three upper shelf 13s. Vertical steel pipes 18 are inserted into the through holes 19. The bottom ends of the two sets of vertical steel pipes 18 are installed with the top of the shelf 13 at the bottom. The two sets of vertical steel pipes 18 can support and fix the four shelf 13s.

[0022] Each group of terminals 16 has sixteen terminals arranged in a 4x4 array. Each group of sixteen terminals is electrically connected to a set of ammeters 15 via cables located inside the test board 14. Since each column of the variable resistors 17 contains two sets of variable resistors 17, each column of two sets of variable resistors 17 corresponds to a set of ammeters 15 and a group of terminals 16. For specific details, please refer to [reference needed]. Figure 1As shown, the two sets of variable resistors 17 in each row are electrically connected to a group of terminals 16 via cables.

[0023] In use, the user can place the charger body 2 on the top surface of the shelf 13, and then electrically connect the charger body 2 to a set of terminal blocks 16 via four sets of cables. At this time, the resistance inside the corresponding terminal block 16 can be changed using two sets of variable resistors 17. Since the voltage inside the charger body 2 is constant, the current can change, causing the pointer on the corresponding ammeter 15 to change. This allows for current and voltage testing of the charger body 2. Because each set of terminal blocks 16 has sixteen terminals, and each set of terminals has a different resistance value, while the charger body 2 only has four sets of cables inside, there are multiple and non-repeating connection methods when electrically connecting the charger body 2 to the terminal blocks 16 via the four sets of cables. This allows for voltage and current testing of the charger body 2 under various load conditions, ensuring the quality of the charger body 2. Therefore, it will not become unusable due to malfunctions in subsequent use.

[0024] Because this device has three layers, and each layer is equipped with several sets of ammeters 15, several sets of terminal blocks 16, and several sets of variable resistors 17, this device can simultaneously perform relevant tests on a large number of charger bodies 2, thereby enabling batch testing and improving the testing efficiency of the charger bodies 2.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
