DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the protection scope and application scope of the present invention are not limited.

[0019] Embodiment: A generator maintenance test bench, such as Figure 1-Figure 4 As shown, it includes a base 1, a fixed disc 2, a ring 3, a placement plate 4, a mounting seat 8, a generator 81, a servo motor 9 and a coupling 91. A fixed disc 2 is welded and fixed on the top of the base 1, and a ring 3 is rotatably arranged on the periphery of the fixed disc 2. A placement plate 4 is welded and fixed on the top of the ring 3. A mounting seat 8 is welded and fixed on the left side of the top of the placement plate 4. A generator 81 is installed on the mounting seat 8 by bolts. A servo motor 9 is installed on the right side of the top of the placement plate 4 by bolts. A coupling 91 is fixedly arranged on the end of the output shaft of the servo motor 9. It also includes an isolation component and a temperature adjustment component. An isolation component for isolating the generator 81 and the servo motor 9 from the outside is arranged on the top of the placement plate 4, and a temperature adjustment component for adjusting the temperature of the internal space of the isolation component is arranged on the isolation component.

[0020] like Figure 1 and Figure 2 As shown, the isolation assembly includes a slide rail 5, a shell 6 and a cover plate 7. The slide rail 5 is welded and fixed symmetrically on the top of the placement plate 4. The shell 6 is slidably arranged between the two slide rails 5. The shell 6 is a square shell with openings on the left and bottom sides. The cover plate 7 is welded and fixed on the left side of the top of the placement plate 4.

[0021] like Figure 1 As shown, the temperature adjustment component includes a hot air blower 101, a cold air blower 102, an energy storage battery 103, a temperature sensor 104, a one-way air outlet valve 105 and a control panel 106. The hot air blower 101 and the cold air blower 102 are installed on the right side of the top of the shell 6, and connecting pipes are provided on the left sides of the hot air blower 101 and the cold air blower 102, and are respectively connected to the interior of the shell 6 through the connecting pipes. The energy storage battery 103 and the control panel 106 are installed in the middle of the top of the shell 6, and the one-way air outlet valve 105 and the temperature sensor 104 are provided on the left side of the top of the shell 6. The hot air blower 101, the cold air blower 102, the energy storage battery 103, and the temperature sensor 104 are all electrically connected to the control panel 106.

[0022] First, the disassembled and repaired generator 81 is installed on the mounting base 8 by bolts, and the end of its output shaft is connected to the coupling 91, and then the generator 81 is electrically connected to the energy storage battery 103, and the servo motor 9 is started through the control panel 106. The servo motor 9 drives the output shaft of the generator 81 to rotate through the coupling 91, so that the generator 81 starts to charge the energy storage battery 103. At this time, it can be observed on the control panel 106 whether the energy storage battery 103 is in a charging state, so as to judge whether the generator 81 is repaired successfully. The energy storage battery 103 is built with a regulating module, and the regulating module can protect the energy storage battery 103, and at the same time, the generator 81 applies a stable output voltage to the energy storage battery 103. When it is necessary to measure the working condition of the generator 81 at different temperatures, slide the outer shell 6 to the left until it fits with the cover plate 7. At this time, the servo motor 9 and the generator 81 are in the outer In the internal space surrounded by the shell 6 and the cover plate 7, the hot air blower 101 or the cold air blower 102 is started through the control panel 106, and the hot air blower 101 or the cold air blower 102 blows hot air or cold air into the above-mentioned internal space, so that it is heated or cooled. The one-way air outlet valve 105 is used to discharge excess air in the above-mentioned internal space to keep the air pressure in the above-mentioned internal space consistent with the outside. The control panel 106 monitors the temperature in the above-mentioned internal space in real time through the temperature sensor 104. When the test temperature is reached, the hot air blower 101 or the cold air blower 102 is turned off, and the servo motor 9 is started at the same time, so that the generator 81 starts to charge the energy storage battery 103. The influence of temperature on the charging effect of the generator 81 can be obtained by comparing the charging rate of the generator 81 to the energy storage battery 103 under room temperature conditions, thereby increasing the test data, and the placement plate 4 can be rotated to meet different usage conditions.

[0023] like Figure 2 and Figure 3 As shown, it also includes a fixed sleeve 111, a sleeve 112 and a push rod 113. The fixed sleeve 111 is fixedly connected to the top of the base 1, and the sleeve 112 is fixedly connected to the fixed sleeve 111. A push rod 113 is slidably arranged in the sleeve 112, and a reset spring 115 is connected between the push rod 113 and the sleeve 112. A plurality of grooves 114 are arranged at intervals on the outer wall of the ring 3. The end of the push rod 113 close to the ring 3 is hemispherical, and the groove 114 is also a hemispherical groove, so the push rod 113 can be fixedly engaged with the groove 114. When the ring 3 rotates, the push rod 113 will be pushed out of the adjacent groove 114.

[0024] Initially, the push rod 113 is stuck in the adjacent groove 114, thereby limiting the rotation of the placement plate 4 and preventing it from rotating easily. When the maintenance personnel rotate the placement plate 4, the ring 3 rotates with the placement plate 4. When the placement plate 4 is rotated, the push rod 113 is pushed away from the groove 114 here. At this time, the reset spring 115 is compressed. When the next groove 114 rotates to the push rod 113, under the reset action of the reset spring 115, the push rod 113 is engaged with the next groove 114. Since a plurality of grooves 114 are provided on the ring 3, the push rod 113 can cooperate with different grooves 114 to achieve rotation limiting of the placement plate 4 at different rotation angles.

[0025] like Figure 1 As shown, a handle 12 is also included, and the handle 12 is welded and fixed on the left side of the top of the shell 6.

[0026] The handle 12 is provided to facilitate maintenance personnel to slide the housing 6 left and right.

[0027] like Figure 4 As shown, a rubber strip 13 is also included. The rubber strip 13 is arranged on the right side of the cover plate 7.

[0028] The rubber strip 13 is provided to increase the friction between the housing 6 and the cover plate 7, so that the connection between the housing 6 and the cover plate 7 is more stable, and the housing 6 will not be easily separated from the cover plate 7 during the test.

[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
