Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to an automatic switching device for an integrated power supply system. Background Art

[0002] In the power network, many users have high requirements for power supply reliability. Once a power outage occurs in some units, it will cause significant economic losses and even casualties. Therefore, in the power supply systems of these units, both main power supply and backup power supply are required. When the main power supply fails, the backup power supply must be immediately put into use to restore power supply. In order to achieve this goal, a dual power switching mechanism is required to automatically switch between the main power supply and the backup power supply.

[0003] Although the integrated power rapid switching devices currently on the market have excellent performance in terms of power switching efficiency and stability, there are some problems that cannot be ignored in the maintenance of the backup power supply contact heads. If the backup power supply contact heads are not used for a long time, dust will often accumulate on their surfaces, especially in industrial environments or outdoor places. The accumulation of dust is more serious. This dust will not only affect the conductive performance of the contact heads, but may also cause poor contact or even short circuits and other faults.

[0004] Chinese patent document CN117691729A discloses a medium voltage integrated power supply fast switching device, comprising a first L-shaped support plate, one side of which is fixed with two sliding rails, and the two sliding rails are respectively slidably matched with a second L-shaped support plate and a third L-shaped support plate; however, there are still the following defects in the implementation process:

[0005] Although the device in the above document can avoid the problem of normal switching operation being affected by damage to the drive motor or lack of power in the normal power supply, the device in the above document cannot provide dust protection for the contact head that switches with the backup power supply during use, so that the contact head that contacts with the backup power supply is exposed to the air for a long time, and a large amount of dust will accumulate on the surface of the contact head. Therefore, when in use, the dust will not only affect the conductive performance of the contact head, but may also cause poor contact or even short circuit and other faults. Utility Model Content

[0006] The purpose of the utility model is to provide an automatic switching device for an integrated power supply system to solve the problems raised in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0008] The automatic switching device for an integrated power supply system comprises a power supply system cabinet body; a support block 1 is fixedly connected to the upper part of the inner cavity of the power supply system cabinet body, a connection block 1 is fixedly connected to one side of the support block 1, a connection block 4 is fixedly connected to the side of the upper end of the support block 1 away from the connection block 1, a quick-cut structure is fixedly connected to the opposite surfaces of the connection block 1 and the connection block 4, a sliding block is fixedly connected to the middle part of the support block 1, a support block 4 is fixedly connected to the opposite surfaces of the connection block 1 and the connection block 4, a common power line is fixedly connected to the middle part of the support block 4, a spare power line is fixedly connected to the middle part of the support block 4, a dust-proof structure is symmetrically fixedly connected to the support block 4, the quick-cut structure comprises two support blocks 2, a slide groove 1 is provided on the opposite surfaces of the two support blocks 2, a connecting frame structure is slidably connected to the inner cavity of the two slide grooves 1, a rubber block 1 is symmetrically fixedly connected to the upper end of the connecting frame structure, a first electric wire is fixedly connected to one side of the connecting frame structure, a second electric wire is fixedly connected to the side of the connecting frame structure away from the first electric wire, a plurality of dust removal structures are symmetrically fixedly connected to the upper ends of the two support blocks 2, and an electric push rod is fixedly connected to the side of the connection block 1 close to the connection block 4.

[0009] A further improvement of the technical solution of the utility model is that the connecting frame structure comprises two fixing blocks, the opposite surfaces of the two fixing blocks are fixedly connected with a connecting block three, and one side of the connecting block three is fixedly connected with a transmission block.

[0010] The above-mentioned technical solution is adopted, in which the first wire and the second wire are fixed respectively by two fixing blocks, so that the connecting frame structure can be moved to drive the first wire and the second wire to move, so that the power supply system cabinet body can make the first wire and the second wire contact with the normal power line and the backup power line respectively, thereby realizing the rapid and reliable switching operation of the power supply, providing a strong guarantee for the stable operation of the power supply system.

[0011] A further improvement of the technical solution of the utility model is that: a moving groove is opened on one side of one of the supporting blocks 2 close to the electric push rod, and the inner cavity of the moving groove is slidably connected with the outer surface of the transmission block.

[0012] The above-mentioned technical solution is adopted, in which the moving trajectory of the transmission block can be limited by the moving groove, so as to prevent the transmission block from leaving the track when driving the connecting frame structure to move. Once the transmission block leaves the predetermined track, the moving positions of the first wire and the second wire will be offset, and thus it is impossible to ensure their accurate contact with the normal power line and the backup power line. Therefore, the existence of the moving groove not only ensures the stable operation of the power switching device, but also greatly improves the reliability and accuracy of the switching operation.

[0013] A further improvement of the technical solution of the utility model is that the output end of the electric push rod is fixedly connected to a side of the transmission block close to the electric push rod.

[0014] The above-mentioned technical solution is adopted, in which the transmission block is driven to move by an electric push rod. When the power supply needs to be switched, the electric push rod can respond quickly and drive the transmission block to move, and then use the transmission block to drive the connecting frame structure to move, thereby realizing accurate switching of the backup power supply, improving the speed and efficiency of power switching, and ensuring the stability and reliability of the switching process, providing strong support for the continuous and stable operation of the power supply system.

[0015] A further improvement of the technical solution of the utility model is that the dust removal structure includes a support block three, the lower end of the support block three is fixedly connected to the upper end of the support block two, and a sponge block is fixedly connected to one side of the support block three close to the connecting frame structure.

[0016] By adopting the above technical solution, the sponge block can clean the upper parts of the first wire and the second wire during the process of the connecting frame structure driving the first wire and the second wire to move, thereby processing the dust falling on them, thereby ensuring the good conductive performance of the contact head and avoiding the occurrence of faults such as poor contact or short circuit.

[0017] A further improvement of the technical solution of the utility model is that the dust-proof structure includes an airbag, the upper end of the airbag is fixedly connected to the lower end of the fourth support block, the upper end of the airbag is fixedly connected to a trachea, and the inner cavity of the trachea is communicated with the inner cavity of the airbag, the output end of the trachea is fixedly connected to a sealing chamber, the lower end of the sealing chamber is fixedly connected to the upper end of the fourth support block, the inner cavity of the sealing chamber is communicated with the inner cavity of the trachea, the inner cavity of the sealing chamber is slidably connected to a rubber block two, and the lower end of the rubber block two is fixedly connected to an outer shell.

[0018] By adopting the above technical solution, the airbag and the air tube cooperate with each other, so that the rubber block 2 can be driven to move in the inner cavity of the sealing chamber, thereby driving the outer shell to rise and fall, so that when the contact of the first electric wire or the contact of the second electric wire is not in contact with the normal power line or the backup power line, the outer shell can be used to seal the contact of the first electric wire or the contact of the second electric wire, thereby not only significantly reducing the contact of the contact with the external environment, effectively preventing the accumulation of dust on the contact, but also preventing the contact from rusting due to moisture.

[0019] A further improvement of the technical solution of the utility model is that one side of the rubber block close to the common power line is V-shaped.

[0020] By adopting the above technical solution, the moving position of the connecting frame structure can be limited by the rubber block 1, thereby improving the contact accuracy between the second electric wire and the common power line or the first electric wire and the backup power line.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides an automatic switching device for an integrated power supply system. The electric push rod can drive the connecting frame structure to move, thereby driving the power supply to switch. The dust removal structure can clean the dust on the contacts of the first wire or the contacts of the second wire, thereby ensuring the cleanliness of the contacts and ensuring their good conductive performance. It can also extend the service life of the contacts and reduce the possibility of malfunctions. The dustproof structure can seal unused contacts, thereby reducing the contact between unused contacts and the outside world and reducing the accumulation of dust, thereby extending the service life of the contacts.

[0038] Example 2

[0039] like Figure 4 , Figure 5 , Figure 6 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the connecting frame structure 63 includes two fixed blocks 631, and the opposite surfaces of the two fixed blocks 631 are commonly fixedly connected with a connecting block three 632, and one side of the connecting block three 632 is fixedly connected with a transmission block 633, and one side of one of the support blocks two 61 close to the electric push rod 9 is provided with a movable groove 611, and the inner cavity of the movable groove 611 is slidably connected with the outer surface of the transmission block 633, and the output end of the electric push rod 9 is fixedly connected with the side of the transmission block 633 close to the electric push rod 9.

[0040] In this embodiment, under normal circumstances, the contacts of the common power cord 12 are in contact with the contacts of the second electric wire 5.

[0041] Example 3

[0042] like Figure 8 As shown, on the basis of Example 2, the utility model provides a technical solution: preferably, the dust-proof structure 8 includes an airbag 81, the upper end of the airbag 81 is fixedly connected to the lower end of the support block four 14, the upper end of the airbag 81 is fixedly connected with an air pipe 82, and the inner cavity of the air pipe 82 is communicated with the inner cavity of the airbag 81, the output end of the air pipe 82 is fixedly connected with a sealing chamber 83, the lower end of the sealing chamber 83 is fixedly connected to the upper end of the support block four 14, the inner cavity of the sealing chamber 83 is communicated with the inner cavity of the air pipe 82, the inner cavity of the sealing chamber 83 is slidably connected with a rubber block two 84, the lower end of the rubber block two 84 is fixedly connected with an outer shell 85, and the side of the rubber block one 64 close to the common power cord 12 is V-shaped.

[0043] In this embodiment, when moving, the surface of the rubber block 1 64 close to the side of the first electric wire 4 is no longer in contact with the surface of the airbag 81 on the same side, so that the rubber block 1 64 no longer exerts a force on the airbag 81, and then the airbag 81 will recover the gas in the inner cavity of the sealing chamber 83 through the air pipe 82, thereby driving the rubber block 2 84 to move upward in the inner cavity of the sealing chamber 83, thereby driving the outer shell 85 to move upward, and then the outer shell 85 will no longer block the contact of the first electric wire 4.

[0044] Example 4

[0045] like Figure 7 As shown, based on Example 3, the utility model provides a technical solution: preferably, the dust removal structure 7 includes a support block three 71, the lower end of the support block three 71 is fixedly connected to the upper end of the support block two 61, and the support block three 71 is fixedly connected to a sponge block 72 on one side close to the connecting frame structure 63.

[0046] In this embodiment, when the first wire 4 moves toward the backup power line 13, the sponge blocks 72 on the same side as the first wire 4 will clean the contact of the first wire 4, thereby cleaning some dust on the contact of the first wire 4, and then the contact of the first wire 4 will be brought into contact with the contact of the backup power line 13 under the push of the electric push rod 9, thereby realizing the switching of the power supply. At the same time, the connecting frame structure 63 will push the second wire 5 to move in the direction away from the common power line 12, and then the rubber block on the same side as the second wire 5 The outer surface of one 64 will contact the surface of the adjacent airbag 81, and the rubber block one 64 will apply force to the airbag 81, and then the airbag 81 on the same side of the second electric wire 5 will push the gas in the inner cavity of the airbag 81 into the inner cavity of the sealing chamber 83 through the air pipe 82, and then push the rubber block two 84 to slide in the inner cavity of the sealing chamber 83, and then the rubber block two 84 will push the outer shell 85 to move downward, and then the outer shell 85 will cover the contact of the second electric wire 5, reduce the contact of the contact of the second electric wire 5 with the outside world, and prevent dust from falling on the contact of the second electric wire 5.

[0047] The working principle of the automatic switching device for the integrated power supply system is described in detail below.

[0048] like Figure 1-8 As shown, when the power supply needs to be switched, first, under normal circumstances, the contact of the common power line 12 contacts the contact of the second wire 5. When the common power line 12 fails and the power supply needs to be switched, the output end of the electric push rod 9 drives the transmission block 633 to move in the inner cavity of the moving groove 611 toward the direction of the common power line 12, and then the transmission block 633 drives the connecting block 3 632 and the fixed block 631 to slide in the inner cavity of the sliding groove 1 62, thereby driving the second wire 5 and the first wire 4 to move;

[0049] When moving, the surface of the rubber block 1 64 close to the first electric wire 4 is no longer in contact with the surface of the airbag 81 on the same side, so that the rubber block 1 64 no longer exerts a force on the airbag 81, and then the airbag 81 recovers the gas in the inner cavity of the sealing chamber 83 through the air pipe 82, thereby driving the rubber block 2 84 to move upward in the inner cavity of the sealing chamber 83, thereby driving the outer shell 85 to move upward, and then the outer shell 85 will no longer block the contact of the first electric wire 4;

[0050] Then, when the first wire 4 moves toward the backup power line 13, the sponge blocks 72 on the same side as the first wire 4 will clean the contact of the first wire 4, thereby cleaning some dust on the contact of the first wire 4, and then the contact of the first wire 4 will be brought into contact with the contact of the backup power line 13 under the push of the electric push rod 9, thereby realizing the switching of the power supply, and at the same time, the connecting frame structure 63 will push the second wire 5 to move in the direction away from the normal power line 12, and then the rubber block 64 on the same side as the second wire 5 will be moved. The outer surface will contact the surface of the adjacent airbag 81, and the rubber block 1 64 will be used to apply force to the airbag 81. Then, the airbag 81 on the same side of the second wire 5 will push the gas in the inner cavity of the airbag 81 into the inner cavity of the sealed chamber 83 through the air tube 82, and then push the rubber block 2 84 to slide in the inner cavity of the sealed chamber 83. Then the rubber block 2 84 will push the outer shell 85 to move downward, and then the outer shell 85 will cover the contact of the second wire 5, reduce the contact of the contact of the second wire 5 with the outside world, and prevent dust from falling on the contact of the second wire 5.

[0051] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
