[0016] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0017] 1. By setting up the connecting shaft, the clamping block, the linkage rod, the contact pad and the alarm light and other structures, it is convenient to perform self-inspection on the generator set in advance when the generator set is used in the future, so as to prevent the internal structure of the generator set from being damaged and affecting the rotation of the shaft, which is difficult to be discovered. The overall practicality is higher. When the generator set is working, the shaft connected to its internal structure will rotate accordingly. At this time, the connecting shaft connected to the shaft will also rotate accordingly, and the rotation of the rotating wheel is realized through the linkage of the rotating wheel, the belt and the driven wheel. At this time, the power-on rods symmetrically arranged on both sides will intermittently contact the contact seat under the rotation of the rotating wheel, thereby realizing the flashing of the alarm light. At this time, if the alarm light flashes normally and regularly, it means that the entire generator set functions normally. If the alarm light flashes without filtering or does not flash, it means that there is a problem with the function of the motor set and it needs to be repaired.

[0018] 2. The auxiliary slide, reset spring, bracket and other structures are provided to facilitate the subsequent reciprocating motion of the power-on rod, thereby facilitating the subsequent flashing of the alarm light. When the rotating wheel rotates and pushes the power-on rod through the contact pad, the power-on rod is slidably connected to the bracket through the auxiliary slide and the reset spring, so the power-on rod drives the auxiliary slide to squeeze the reset spring to achieve the deformation of the reset spring. Then, the reverse force generated by the deformation of the reset spring can be used to reset the power-on rod when the contact pad is separated from the power-on rod. This reciprocating motion can facilitate the subsequent flashing of the alarm light.

[0019] 3. By setting up structures such as air coolers, filter cotton stacking plates and honeycomb carbon plates, it is convenient to quickly cool the motor group that has generated high temperature after working for a long time, so as to prevent the high temperature generated by the long-term operation of the motor group from causing damage to its internal electrical components and affecting the normal operation of the subsequent motor group. The overall practicality is higher. When the air cooler is working, air will be drawn into the inside of the fixed box. At this time, the filter cotton stacking plates and honeycomb carbon plates are used to filter and remove impurities from the air. The air after the impurity removal treatment will be cooled by the air cooler, and then the cooled air will be used to cool the motor group. BRIEF DESCRIPTION OF THE DRAWINGS

The other end is connected with a linkage structure, a mounting plate 17 is fixedly provided on one end surface of the unit frame 1, and a fixing box 18 is installed on one end surface of the mounting plate 17, an alarm light 19 is fixedly provided on the front end surface of the fixing box 18, and a wire 20 is connected to one end of the alarm light 19, and a contact seat 21 is connected to the other end of the wire 20, a bracket 22 is fixedly provided on the bottom of one side of the fixing box 18, and a power rod 23 is penetrated through the inner side of the bracket 22, an auxiliary slide plate 24 is sleeved on the outer side of one end of the power rod 23, and a reset spring 25 is fixedly connected to the surface of one end of the auxiliary slide plate 24;

[0031] During operation, the controller 3 provided can be used to control the operation of the motor group 2. When the motor group 2 is working, since the shaft rod 4 extends inside the motor group 2 and is connected to the shaft inside the motor group 2, the shaft rod 4 will rotate when the motor group 2 is working. Before the shaft rod 4 rotates, the cylinder 7 drives the movable plate 8 connected to its output end to move accordingly, and then the movable plate 8 drives the connecting shaft 9 to move laterally, and then the connecting shaft 9 is used to push the clamping block 10 laterally, and one end of the clamping block 10 is input into the inner side of the clamping groove 5. At this time, when the clamping block 10 is fully engaged with the clamping groove 5, the clamping connection between the shaft rod 4 and the connecting shaft 9 can be realized, and then when the shaft rod 4 rotates, the synchronous rotation of the connecting shaft 9 can be realized, and then the rotation of the connecting shaft 9 can be used to realize the subsequent rotation of the driving wheel 11, the inner tooth belt 12, the driven wheel 13 and the rotating wheel 15, and under the rotation of the rotating wheel 15, the contact pad 16 will push the power rod 23. , thereby realizing the longitudinal movement of the power-on rod 23, and when the power-on rod 23 moves longitudinally, it will drive the auxiliary slide plate 24 to move longitudinally as well. At this time, the longitudinal movement of the auxiliary slide plate 24 drives the reset spring 25 to deform and generate a reverse force, and the power-on rod 23 will contact the contact seat 21 at the same time. At this time, when the two are in contact, the wire 20 transmits the signal to the alarm light 19, so that the alarm light 19 lights up, and under the rotation of the rotating wheel 15, the contact pad 16 is intermittently in contact with the power-on rod 23. Therefore, when the contact pad 16 is separated from the power-on rod 23, the reverse force generated by the deformation of the reset spring 25 can facilitate the subsequent rebound of the power-on rod 23, so that the power-on rod 23 is separated from the contact seat 21, and then the alarm light 19 is extinguished. In this way, the flashing of the alarm light 19 can be realized, which is convenient for the subsequent use of the flashing alarm light 19 to determine whether there is a problem with the motor group 2, affecting the subsequent normal operation, thereby achieving the purpose of self-inspection.

[0033] During operation, since the connecting shaft 9 and the driving wheel 11 are fixedly connected, when the connecting shaft 9 rotates, the driving wheel 11 will rotate accordingly. At this time, the driving wheel 11 drives the internal toothed belt 12 meshing on its surface to move accordingly, and then the internal toothed belt 12 drives the driven wheel 13 meshing on the inner side of the other end to rotate accordingly, and then the rotation of the driven wheel 13 drives the linkage rod 14 to rotate accordingly, which is convenient for the subsequent rotation of the linkage rod 14 to realize the rotation of the rotating wheel 15, and when the rotating wheel 15 rotates, it will drive the contact pads 16 symmetrically arranged at both ends of its surface to move accordingly, which is convenient for the subsequent use of the contact pads 16 to push the power rod 23.

[0034] An air inlet groove 26 is formed on one end surface of the fixed box 18, a ventilation cavity 27 is formed on the inner side of the fixed box 18, and an air outlet groove 28 is formed on one side of the bottom of the fixed box 18;

[0035] During operation, air enters the inner side of the ventilation cavity 27 through the air inlet groove 26, and is filtered by the filtering structure arranged on the inner side of the ventilation cavity 27. Finally, the filtered air is output through the air outlet groove 28, so that the motor group 2 can be cooled by the exhaust cold air.

[0036] A filter cotton stacking plate 29 is fixedly arranged in the inner cavity of the fixed box 18, and a fixing seat 30 is arranged on one side of the filter cotton stacking plate 29, a honeycomb carbon plate 31 is installed on the inner side of the fixing seat 30, and a cooling fan 32 is arranged on one side of the honeycomb carbon plate 31, and a temperature sensor 33 is fixedly arranged on one side of the mounting plate 17 away from the fixed box 18;

[0037] When working, the air cooler 32 draws air into the inner side of the ventilation cavity 27 through the multiple air inlet grooves 26 opened on the surface of one end of the fixed box 18. At this time, the air circulates on the inner side of the ventilation cavity 27 and passes through the filter cotton stacking plate 29. The filter cotton arranged on the inner side of the filter cotton stacking plate 29 is then used to perform preliminary filtering and purification on the air, and then the honeycomb carbon plate 31 made of activated carbon is used to further filter and purify the air to achieve air purification and dust removal. The purified air will be cooled and cooled by the air cooler 32, and the treated cold air will be discharged through the air outlet groove 28, which is convenient for the subsequent air cooling and cooling of the working motor group 2, and the temperature sensor 33 is set to monitor the temperature of the motor group 2 itself in real time during operation.

[0038] The shaft rod 4 is rotatably connected to the motor unit 2, and the clamping groove 5 and the shaft rod 4 form an integrated structure;

[0039] When working, the motor group 2 works through the rotating shaft connected to the shaft 4 arranged on the inner side thereof, which can facilitate the subsequent rotation of the shaft 4, and then utilize the rotation of the shaft 4 to realize the subsequent rotation of the connecting shaft 9 engaged with the other end thereof.

[0040] The movable plate 8 is slidably connected to the fixed plate 6 through the cylinder 7, and the cylinder 7 is symmetrically distributed along the vertical center line of the movable plate 8. The connecting shaft 9 is rotatably connected to the movable plate 8 through the bearing seat, and the movable plate 8 and the fixed plate 6 are distributed in a flat shape;

[0041] During operation, the cylinder 7 drives the movable plate 8 to move accordingly, and the movement of the movable plate 8 drives the connecting shaft 9 to move synchronously therewith, thereby facilitating the subsequent engagement connection between the connecting shaft 9 and the shaft rod 4 .

[0042] The driven wheel 13 is connected to the driving wheel 11 through the inner tooth belt 12, and the driving wheel 11 and the driven wheel 13 are connected to the inner tooth belt 12 through the teeth on the surface thereof.

[0043] During operation, since the driving wheel 11 is meshed and connected with the internal toothed belt 12, and the driven wheel 13 is also meshed and connected with the internal toothed belt 12, when the driving wheel 11 rotates, the movement of the internal toothed belt 12 can be conveniently realized subsequently, and then the movement of the internal toothed belt 12 can be used to realize the rotation of the driven wheel 13, so that the rotation of the driven wheel 13 can be conveniently used to realize the synchronous rotation of the linkage rod 14.

[0044] The power rod 23 is slidably connected to the bracket 22 via a return spring 25, and the power rod 23 and the bracket 22 are vertically distributed, and the power rod 23 is symmetrically distributed along the transverse center line of the fixed box 18;

[0045] During operation, the rotation of the rotating wheel 15 will cause the power-on rod 23 to move longitudinally, and then the longitudinal movement of the power-on rod 23 will drive the auxiliary slide 24 to move longitudinally. At this time, the auxiliary slide 24 pulls the reset spring 25 to realize the deformation of the reset spring 25, and then the reverse force generated by the deformation of the reset spring 25 can be used to reset the power-on rod 23 when the rotating wheel 15 is separated from the power-on rod 23, so as to facilitate the subsequent flashing of the alarm light 19.

[0046] The air inlet grooves 26 are evenly distributed along the front surface of the fixed box 18, and the air inlet grooves 26 and the fixed box 18 form an integrated structure;

[0047] During operation, the air cooler 32 draws air into the inner side of the ventilation cavity 27 through the air inlet groove 26, and then discharges the air through the air outlet grooves 28 connected on both sides of the ventilation cavity 27, thereby achieving air circulation and facilitating the subsequent use of cold air to cool the motor unit 2.

[0048] The filter cotton stacking plate 29 and the honeycomb carbon plate 31 are distributed in a flat shape, and the internal structure of the filter cotton stacking plate 29 is formed by stacking filter cottons;

[0049] During operation, the air will pass through the filter cotton stacking plate 29 and the honeycomb carbon plate 31 in sequence. When the air passes through the filter cotton stacking plate 29, the filter cotton arranged on the inner side thereof can be used to perform preliminary filtering and adsorption treatment on the air, and then the honeycomb carbon plate 31 composed of activated carbon can be used to further filter and purify the air.

[0050] Working principle: The controller 3 is set to control the operation of the motor group 2. When the motor group 2 is working, since the shaft 4 extends to the inner side of the motor group 2 and is connected to the shaft inside the motor group 2, the shaft 4 will rotate when the motor group 2 is working. Before the shaft 4 rotates, the cylinder 7 drives the movable plate 8 connected to its output end to move accordingly, and then the movable plate 8 drives the connecting shaft 9 to move horizontally, and then the connecting shaft 9 is used to push the clamping block 10 horizontally, and one end of the clamping block 10 is input into the inner side of the clamping groove 5. At this time, when the clamping block 10 is fully engaged with the clamping groove 5, the clamping connection between the shaft 4 and the connecting shaft 9 can be realized, and then when the shaft When the rod 4 rotates, the synchronous rotation of the connecting shaft 9 can be realized. Since the connecting shaft 9 and the driving wheel 11 are fixedly connected, when the connecting shaft 9 rotates, the driving wheel 11 will rotate accordingly. At this time, the driving wheel 11 drives the inner tooth belt 12 meshing on its surface to move accordingly, and then the inner tooth belt 12 drives the driven wheel 13 meshing on the inner side of the other end to rotate accordingly, and then the rotation of the driven wheel 13 is used to drive the linkage rod 14 to rotate accordingly, which is convenient for the subsequent use of the rotation of the linkage rod 14 to realize the rotation of the rotating wheel 15, and when the rotating wheel 15 rotates, it will drive the contact pads 16 symmetrically arranged at both ends of its surface to move accordingly, which is convenient for the subsequent use The contact pad 16 pushes the energizing rod 23, and the rotation of the rotating wheel 15 causes the contact pad 16 to push the energizing rod 23, thereby realizing the longitudinal movement of the energizing rod 23. When the energizing rod 23 moves longitudinally, the auxiliary slide plate 24 is driven to move longitudinally. At this time, the longitudinal movement of the auxiliary slide plate 24 drives the return spring 25 to deform and generate a reverse force. At the same time, the energizing rod 23 contacts the contact seat 21. At this time, when the two are in contact, the wire 20 transmits a signal to the alarm light 19, so that the alarm light 19 lights up. Under the rotation of the rotating wheel 15, the contact pad 16 is in intermittent contact with the energizing rod 23. Therefore, when the contact pad 16 is separated from the energizing rod 23, The reverse force generated by the deformation of the reset spring 25 can facilitate the subsequent rebound of the Xi'an power rod 23, so that the power rod 23 is separated from the contact seat 21, and then the alarm light 19 is extinguished. In this way, the alarm light 19 can flash, which is convenient for the subsequent use of the flashing alarm light 19 to determine whether there is a problem with the motor group 2, affecting the subsequent normal operation, and thus achieving the purpose of self-inspection. When the motor group 2 needs to be cooled by air, the air cooler 32 works through the multiple air inlet grooves 26 opened on the surface of one end of the fixed box 18 to draw air into the inner side of the ventilation cavity 27. At this time, the air circulates inside the ventilation cavity 27 and passes through the filter cotton stacking plate 29.The filter cotton arranged inside the filter cotton stacking plate 29 is then used to perform preliminary filtering and purification on the air, and then the honeycomb carbon plate 31 made of activated carbon is used to further filter and purify the air, so as to achieve purification and dust removal of the air. The purified air will be cooled by the air cooler 32, and the treated cold air will be discharged through the air outlet slot 28, so as to facilitate the subsequent air cooling and cooling of the working motor group 2. The temperature sensor 33 is used to monitor the temperature of the motor group 2 in real time when it is working.
