Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of five-proof electromagnetic lock devices, specifically relating to outdoor five-proof electromagnetic lock devices. Background Technology
[0002] The term "five preventions" is a shorthand for the five anti-misoperation functions that high-voltage electrical equipment should possess to ensure personal safety. It is one of the important measures for power safety. The five preventions are: preventing accidental opening or closing of circuit breakers; preventing opening or closing of disconnecting switches under load; preventing the connection (or closing) of grounding wires (grounding switches) while energized; preventing the closing of circuit breakers with grounding wires (grounding switches) connected; and preventing accidental entry into energized compartments.
[0003] However, traditional devices still have the following problems when in use: 1. Because the traditional five-proof electromagnetic lock interlocking function introduces terminal box switches and knife switches as auxiliary contacts, and the reliability of these auxiliary contacts is low, they often fail to be in the correct position or even make mistakes, so the safety needs to be strengthened.
[0004] 2. Electromagnetic lock power supply and auxiliary contacts are often connected by cables, and the outer shell is usually a plastic flexible tube. When left outdoors for a long time, it is prone to aging and damage, causing insulation short circuits and making it difficult to operate the grounding switch on site. Summary of the Invention
[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an outdoor five-proof electromagnetic lock device, so that the locking function is no longer used in combination with other functions, while ensuring the safety of the device.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an outdoor five-proof electromagnetic lock device, comprising a cabinet, the cabinet having an internal cavity, an electromagnetic lock fixedly connected to one inner wall of the cavity, a lock cylinder device fixedly connected to the outer wall of the electromagnetic lock, a fixing rod fixedly connected to one end of the lock cylinder device, a fixing plate fixedly installed on the inner wall of the cavity, the end of the fixing rod away from the electromagnetic lock being fixedly connected to the outer wall of the fixing plate, an operating lever rotatably connected to the inner wall of the cavity, the cabinet having a hole communicating with the cavity, the outer wall of the operating lever being movably connected to the inner wall of the hole, and one end of the operating lever being... An operating wheel is fixedly connected to the outer wall of the control lever. An adjusting hinge is fixedly connected to the outer wall of the control lever. A connecting rod is hinged to the end of the adjusting hinge away from the control lever. A through hole is opened on the outer wall of the fixed rod. The inner wall of the through hole is movably connected to the outer wall of the connecting rod. A limit plate is fixedly installed on one side of the inner wall of the cavity. The inner wall of the limit plate is movably connected to the outer wall of the connecting rod. A connecting iron plate is fixedly installed on one side of the outer wall of the fixed plate. A load-blocking disconnect switch is fixedly connected to the top outer wall of the connecting iron plate. A grounding switch is fixedly connected to the outer wall of the control lever. A connecting block is fixedly connected to one side of the outer wall of the connecting iron plate.
[0007] Specifically, the operator rotates the control wheel to make the grounding switch on the control lever contact the connecting block for grounding. At the same time, the connecting rod linked to the control lever will move downwards and disengage from the through hole due to the rotation of the control lever. Only after it is completely disengaged can the lock cylinder rotate and operate. The lock cylinder can only rotate and operate normally after the operator rotates the control wheel to completely ground the device. This device ensures that the electromagnetic lock's locking function does not affect the grounding protection function. However, the electromagnetic lock cannot be opened when the grounding protection function is not in operation, thus ensuring the safety of the device.
[0008] Preferably, a grounding bar is fixedly connected to the inner wall of the cavity, and a grounding copper wire is fixedly connected to the outer wall of the grounding bar. The end of the grounding copper wire away from the grounding bar is fixedly connected to the outer wall of the grounding switch.
[0009] Specifically, only after rotating the control lever to bring the grounding switch into contact with the connecting block can the load-blocking disconnect switch be connected to the grounding busbar to achieve the grounding function.
[0010] Preferably, a hinge numbered 1 is fixedly installed on one side of the control wheel of the cabinet, and a tempered glass cover is provided on one side of the outer wall of the cabinet, the tempered glass cover being hinged to the cabinet via the hinge numbered 1.
[0011] Specifically, the control wheel is protected by a tempered glass cover to prevent unauthorized personnel from touching or operating the device, which could affect the electrical operation of the invention.
[0012] Preferably, a second hinge is fixedly connected to one side of the outer wall of the cavity, and a cabinet door is provided on one side of the outer wall of the cabinet. The cabinet door is hinged to the outer wall of the cabinet via the second hinge, and a lock cover is fixedly connected to the outer wall of the cabinet door. The lock cover is electromagnetically connected to an electromagnetic lock.
[0013] Specifically, the electromagnetic connection between the lock head cover and the electromagnetic lock achieves a strong locking effect. Only when the grounding switch and the connecting block are in complete contact to achieve a grounding effect will the electromagnetic connection between the lock head cover and the electromagnetic lock be lost. By setting this device, the safety of the invention is improved and accidental activation is avoided.
[0014] Preferably, the bottom outer wall of the cabinet has an opening that communicates with the cavity, a conduit is fixedly connected to the inner wall of the opening, a cable is movably connected to the inner wall of the conduit, and the cable is electrically connected to the transmission port of the electromagnetic lock.
[0015] Specifically, the device of this invention is powered by power transmission through cables. The conduit is made of anti-oxidation metal rigid pipe and laid underground. The power is introduced from underground to the device, which reduces the outdoor exposure while strengthening the pipe's anti-aging properties and reducing the possibility of insulation short circuits.
[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. By rotating the control wheel, the operator makes the grounding switch on the control lever contact with the connecting block to establish grounding. At the same time, the connecting rod linked to the control lever will move downwards and disengage from the through hole due to the rotation of the control lever. Only after it is completely disengaged can the lock cylinder rotate and operate. The lock cylinder can only rotate and operate normally after the operator has completely grounded the device by rotating the control wheel. This device ensures that the electromagnetic lock's locking function will not affect the grounding protection function. However, the electromagnetic lock cannot be opened when the grounding protection function is not in operation, thus ensuring the safety of the device.
[0017] 2. The electromagnetic connection between the lock head cover and the electromagnetic lock achieves a strong locking effect. Only when the grounding switch and the connecting block are in complete contact to achieve the grounding effect will the lock head cover and the electromagnetic lock lose their electromagnetic connection. By setting this device, the safety of the invention is improved and accidental activation is avoided.
[0018] 3. Power is supplied to the device of the present invention through cable power transmission. The conduit is made of anti-oxidation metal rigid pipe and laid underground. The power is introduced from underground to the device, which reduces the outdoor exposure part, strengthens the anti-aging of the pipe and reduces the possibility of insulation short circuit.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Please see Figures 1-5 This invention provides a technical solution: an outdoor five-proof electromagnetic lock device, including a cabinet 1, with a cavity 2 inside the cabinet 1. An electromagnetic lock 3 is fixedly connected to the inner wall of one side of the cavity 2, and a lock cylinder device is fixedly connected to the outer wall of the electromagnetic lock 3. A fixing rod 4 is fixedly connected to one end of the lock cylinder device. A fixing plate 5 is fixedly installed on the inner wall of the cavity 2. The end of the fixing rod 4 away from the electromagnetic lock 3 is fixedly connected to the outer wall of the fixing plate 5. An operating lever 7 is rotatably connected to the inner wall of the cavity 2. The cabinet 1 has a hole communicating with the cavity 2. The outer wall of the operating lever 7 is movably connected to the inner wall of the hole. An operating wheel is fixedly connected to the outer wall of one end of the operating lever 7. 8. An adjusting hinge 9 is fixedly connected to the outer wall of the control lever 7. A connecting rod 10 is hinged to the end of the adjusting hinge 9 away from the control lever 7. A through hole 22 is opened on the outer wall of the fixed rod 4. The inner wall of the through hole 22 is movably connected to the outer wall of the connecting rod 10. A limit plate 21 is fixedly installed on one side of the inner wall of the cavity 2. The inner wall of the limit plate 21 is movably connected to the outer wall of the connecting rod 10. A connecting iron plate 11 is fixedly installed on one side of the outer wall of the fixed plate 5. A load-blocking disconnect switch 6 is fixedly connected to the top outer wall of the connecting iron plate 11. A grounding switch 13 is fixedly connected to the outer wall of the control lever 7. A connecting block 14 is fixedly connected to one side of the outer wall of the connecting iron plate 11.
[0023] In this invention, the operator rotates the control wheel 8 to make the grounding switch 13 on the control lever 7 contact the connecting block 14 for grounding. At the same time, the connecting rod 10 linked to the control lever 7 will move downward and disengage from the through hole 22 due to the rotation of the control lever 7. Only after it is completely disengaged can the lock cylinder rotate and run. The lock cylinder can only rotate and run normally after the operator rotates the control wheel 8 to completely ground the device. This device ensures that the locking function of the electromagnetic lock 3 will not affect the grounding protection function. However, the electromagnetic lock 3 cannot be opened when the grounding protection function is not in operation, thus ensuring the safety of the device.
[0024] Specifically, a grounding busbar 15 is fixedly connected to the inner wall of cavity 2, and a grounding copper wire 16 is fixedly connected to the outer wall of grounding busbar 15. The end of the grounding copper wire 16 away from grounding busbar 15 is fixedly connected to the outer wall of grounding switch 13.
[0025] In this invention, the load isolation switch 6 can only be connected to the grounding busbar 15 after the grounding switch 13 is brought into contact with the connecting block 14 by rotating the control lever 7, so as to achieve the grounding function.
[0026] Specifically, a hinge 17 is fixedly installed on one side of the control wheel 8 in the cabinet 1, and a tempered glass cover 18 is provided on one side of the outer wall of the cabinet 1. The tempered glass cover 18 is hinged to the cabinet 1 through the hinge 17.
[0027] In this invention, the control wheel 8 is protected by a tempered glass cover 18 to prevent non-professional personnel from touching or operating the device, which could affect the power operation of the invention.
[0028] Specifically, a second hinge 19 is fixedly connected to one side of the outer wall of cavity 2, and a cabinet door 20 is provided on one side of the outer wall of cabinet 1. The cabinet door 20 is hinged to the outer wall of cabinet 1 through the second hinge 19. A lock cover 23 is fixedly connected to the outer wall of cabinet door 20, and the lock cover 23 is electromagnetically connected to electromagnetic lock 3.
[0029] In this invention, a strong locking effect is achieved through the electromagnetic connection between the lock head cover 23 and the electromagnetic lock 3. Only after the grounding switch 13 and the connecting block 14 are in complete contact and grounding is achieved will the lock head cover 23 and the electromagnetic lock 3 lose their electromagnetic connection. By setting this device, the safety of this invention is improved and accidental activation is avoided.
[0030] Specifically, the bottom outer wall of the cabinet 1 has an opening that communicates with the cavity 2. A conduit 12 is fixedly connected to the inner wall of the opening, and a cable is movably connected to the inner wall of the conduit 12. The cable is electrically connected to the transmission port of the electromagnetic lock 3.
[0031] In this invention, the power supply to the device is provided by the power transmission of the cable. The conduit 12 is made of anti-oxidation metal rigid pipe and is laid underground. It is introduced into the device from the underground, which reduces the outdoor exposure part, strengthens the anti-aging of the pipe and reduces the possibility of insulation short circuit.
[0032] The working principle and usage process of this invention: The operator rotates the control wheel 8 to bring the grounding switch 13 on the control lever 7 into contact with the connecting block 14 for grounding. Simultaneously, the connecting rod 10, linked to the control lever 7, moves downwards and disengages from the through hole 22 due to the rotation of the control lever 7. Only after complete disengagement can the lock cylinder rotate. The lock cylinder can only rotate normally after the operator fully grounds the device by rotating the control wheel 8. This device ensures that the locking function of the electromagnetic lock 3 does not affect the grounding protection function; however, the electromagnetic lock 3 cannot be opened when the grounding protection function is not in operation, thus ensuring the safety of the device. Only after rotating the control lever 7 to bring the grounding switch 13 into contact with the connecting block 14 can the load isolation switch 6 be connected to the grounding... The 15-phase connection achieves grounding. The control wheel 8 is protected by a tempered glass cover 18 to prevent unauthorized personnel from touching or operating the device, which could affect the electrical operation of the invention. The electromagnetic connection between the lock cover 23 and the electromagnetic lock 3 achieves a strong locking effect. Only after the grounding switch 13 and the connecting block 14 are in complete contact and grounding is achieved will the electromagnetic connection between the lock cover 23 and the electromagnetic lock 3 be lost. This device improves the safety of the invention and avoids accidental contact. The device is powered by the cable. The conduit 12 is an anti-oxidation metal rigid pipe laid underground, leading from underground to the device. This reduces the outdoor exposure while strengthening the pipe's anti-aging properties and reducing the possibility of insulation short circuits.
[0033] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
