Description

Technical Field

[0001] The invention relates to the technical field of switches, and in particular to a direct current load switch. Background Art

[0002] A load switch is a switching device used to control and protect circuits in electrical equipment. It usually has a high withstand voltage and a strong current carrying capacity. It can work in a high voltage and high current environment. It can connect or disconnect the circuit when it is energized to achieve control of the circuit. The working principle of the load switch is mainly to control the circuit by connecting and disconnecting the contacts. When the load switch is operated, its active contact will contact or separate from the main static contact, thereby connecting or disconnecting the circuit. The existing technology mostly pre-stores energy in the energy storage spring. When the active contact needs to be connected or disconnected with the main static contact, the energy is released by the energy storage spring to drive the main drive shaft to deflect, so that the main drive shaft drives the active contact to deflect, thereby connecting or disconnecting the circuit. The energy storage spring needs to be compressed during the energy storage process, and in the process of waiting to disconnect or connect the circuit, the energy storage spring is always in a compressed state, which affects the elastic coefficient of the energy storage spring, thereby affecting the subsequent release of elastic potential energy of the energy storage spring, thereby affecting the control of the circuit and reducing the safety of the circuit.

[0003] In view of the above-mentioned related technologies, it is urgently necessary to design and develop a DC load switch that can quickly complete the energy storage work of the energy storage spring before the circuit needs to be disconnected or connected, so as to store energy for the main drive shaft and drive the active contact to deflect when the circuit is disconnected or connected. When the circuit remains disconnected or connected, the energy storage spring is in a free state, which effectively improves the service life of the energy storage spring and ensures the safety of the circuit.

The energy storage spring 2 releases the stored energy downward, driving the main drive shaft 13 to deflect, thereby driving the active contact 12 to disengage from the main static contact 11, and the circuit is disconnected. At this time, the energy storage spring 2 is in a free state.

[0045] Reference Figure 1 and Figure 4 As shown, when the circuit needs to be connected, the drive shaft 71 rotates in the opposite direction, the shaft 71 drives the transfer rod 1 72 and the transfer rod 2 74 to rotate in the opposite direction simultaneously, the transfer rod 1 72 drives the transfer plate 73 to rotate in the opposite direction through the bent rod 721, and the transfer plate 73 drives the energy storage spring 2 to deflect through the connecting column 77 and the connecting block 76, so that the spring is compressed upward, and when the energy storage spring 2, the transfer ring 75, the connecting rod 751, the transfer column and the rotating handle 741 are in the same horizontal position, the energy storage spring 2 is fully stored, and at this time the torsion spring 79 is in a stretched state. To maintain the stability of the energy storage state, when the first drive mechanism 8 gives a certain trigger force to the torsion spring 79 through the rotating shaft 71, the torsion spring 79 deflects, and the balance state of the energy storage spring 2, the adapter ring 75, the connecting rod 751, the adapter column and the rotating handle 741 is broken, and the energy storage spring 2 releases the stored energy upward, driving the main driving shaft 13 to deflect, thereby driving the active contact 12 to engage the main static contact 11, and the circuit is connected, that is, when the circuit remains disconnected or connected, the energy storage spring 2 is in a free state, which effectively improves the service life of the energy storage spring 2 and ensures the safety of the circuit.

[0046] Reference Figure 1 and Figure 5As shown, the shock absorbing mechanism 6 includes a mounting column 61, a hydraulic buffer 62 and a rotating handle 63. The mounting column 61 is fixedly arranged in the mounting seat 1, the hydraulic buffer 62 is arranged in the mounting seat 1, the hydraulic buffer 62 is rotatably sleeved on the mounting column 61, and the rotating handle 63 is hingedly arranged at the output end of the hydraulic buffer 62, and the rotating handle 63 is rotatably sleeved on the main drive shaft 13.

[0047] Reference Figure 1 and Figure 5 As shown, when the energy storage spring 2 releases the stored energy instantaneously, the main drive shaft 13 will produce a certain up and down vibration. At this time, through the connection between the hydraulic buffer 62, the rotating handle 63 and the main drive shaft 13, when the main drive shaft 13 drives the rotating handle 63 to vibrate, the hydraulic buffer 62 can give the rotating handle 63 a certain buffering force, thereby slowing down the vibration of the main drive shaft 13, thereby improving the stability of the rotation of the main drive shaft 13, and further improving the stability of the switch operation.

[0048] Reference Figure 1 As shown, the first driving mechanism 8 includes a motor 81, a driving gear 82 and a driven gear 83. The motor 81 is fixedly arranged in the mounting seat 1, the driving gear 82 is fixed on the output shaft of the motor 81, and the driving gear 82 is rotatably arranged in the mounting seat 1. The axial centerline direction of the driving gear 82 coincides with the axial centerline direction of the output shaft of the motor 81.

[0049] Reference Figure 1 As shown, the driven gear 83 is fixed on the rotating shaft 71 , the axis direction of the driven gear 83 coincides with the axis direction of the rotating shaft 71 , the driven gear 83 is rotatably disposed in the mounting seat 1 , and the driving gear 1 82 is meshed with the driven gear 83 .

[0050] The implementation principle of Example 1 is: when the rotating shaft 71 needs to be driven to rotate, the driving motor 81 drives the driving gear 1 82 to rotate, the driving gear 1 82 drives the driven gear 83 to rotate, and the driven gear 83 drives the rotating shaft 71 to rotate, so as to drive the rotating shaft 71 to rotate.

[0051] Example 2 Reference Figure 1 As shown, the second driving mechanism 9 includes a selection switch, a rotating shaft 91, a second driving gear 92 and a handle 93. The rotating shaft 91 is rotatably arranged in the mounting seat 1. The length direction of the rotating shaft 91 is the same as the length direction of the main driving shaft 13. The second driving gear 92 is fixedly arranged on the rotating shaft 91. The axis centerline direction of the second driving gear 92 coincides with the axis centerline direction of the rotating shaft 91. The second driving gear 92 is rotatably arranged in the mounting seat 1, and the second driving gear 92 is meshed with the driven gear 83.

[0052] Reference Figure 1As shown, the selection switch is arranged in the mounting seat 1 , the selection switch is connected to the motor 81 , the handle 93 can be sleeved on the rotating shaft 91 , and the handle 93 can be rotatably inserted on the mounting seat 1 .

[0053] The implementation principle of Example 2 is: when the handle 93 is inserted into the mounting base 1 and sleeved on the rotating shaft 91, the selection switch controls the motor 81 to be unable to access the circuit, and the handle 93 is turned to drive the driving gear 2 92 to rotate, and the driving gear 2 92 drives the driven gear 83 to rotate, thereby facilitating the rotation of the rotating shaft 91. When a problem occurs in the circuit of the motor 81, the handle 93 can be used to manually operate to improve the safety of the circuit. If the motor 81 is required to drive the rotating shaft 91 to rotate, the handle 93 needs to be pulled out, and the selection switch controls the motor 81 to work normally. Two ways of driving the rotating shaft 91 are provided to avoid the handle 93 rotating at the same time when the motor 81 is working, causing harm to the staff.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
