Description

Technical Field

[0001] The present invention relates to the technical field of relay protection devices, and in particular to a relay protection information transmission device for multiple compatibility interfaces. Background Art

[0002] A relay protection device refers to an automated measure and equipment that can promptly send warning signals to operating personnel on duty, or directly send a tripping command to the controlled circuit breaker to terminate the development of these events when a fault occurs in an electric component in the power system or in the power system itself, endangering the safe operation of the power system.

[0003] At present, in order to ensure multi-compatibility, the information transmission interface of the relay protection device is usually designed to be more than two to ensure that it is suitable for different devices. However, the information transmission interface of the existing relay protection device is directly fixed on the device. When there are too many interfaces, the size of the device will be increased, and too many interfaces are difficult to distinguish quickly during connection, which can easily cause wrong connection, affect the normal transmission of information, and be inconvenient to use. Summary of the invention

[0004] In order to achieve the above purposes of being able to switch between multiple interfaces, saving installation space, being easy to use, preventing interface contamination, automatically detecting the tightness of the interface, and stabilizing information transmission, the present invention is implemented through the following technical scheme: A relay protection information transmission device for multiple compatible interfaces, comprising a transmission mechanism, the transmission mechanism comprising a shell, a baffle door hinged on the outer side of the shell, an inner joint fixedly connected to the inside of the shell, a knob inserted on the outer side of the shell, a buffer spring sleeved on the outer side of the knob, a worm gear slidably connected to the inside of the knob, a gear rod clamped on the side of the knob close to the inside of the shell, a worm wheel fixedly connected to the inner wall of the shell, and a gear fixedly connected to the front side of the worm wheel.

[0005] Furthermore, a locking groove is provided on the outer side of the shell, and an indicator plate and a warning light are fixedly connected to the outer side. The locking groove is used to fix the knob, the indicator plate is convenient for switching the interface, and the warning light is used to indicate that the internal interface is damaged.

[0006] Furthermore, a clockwork spring is fixed inside the baffle door so that the baffle door can automatically seal the outer shell.

[0007] Furthermore, a locking block is fixedly connected to one side of the knob close to the housing and is used in conjunction with the locking slot.

[0008] Furthermore, the gear rod is slidably connected to the inner wall of the shell, and the gear rod is meshed with the gear, so the transmission is stable.

[0009] Furthermore, the gear rod is slidably connected to the inner wall of the shell, and the gear rod is meshed with the gear, so that the gear rod will not rotate with the knob.

[0010] Furthermore, it also includes a conversion mechanism, which is fixedly connected to the inside of the transmission mechanism, and the conversion mechanism includes a conversion wheel, a crank wheel is inserted into the inside of the conversion wheel, an external rod and an internal rod are slidably connected inside the crank wheel, an external interface is installed with a screw on the side of the external rod away from the crank wheel, a sliding rod is slidably connected to the side of the internal rod away from the crank wheel, a detection spring is sleeved on the outer side of the sliding rod, a detection switch is fixedly connected to the side of the sliding rod close to the internal rod, and an internal interface is installed with a screw on the side of the sliding rod away from the internal rod.

[0011] Furthermore, the outer interface and the inner interface are symmetrical about the center of the conversion wheel, and there are no less than three groups of outer interfaces and inner interfaces, so the connection is stable and space is saved.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The relay protection information transmission device for multiple compatible interfaces, by pulling the knob away from the locking groove, the knob drives the gear rod to move, the gear rod drives the gear to rotate, the gear drives the crank wheel to rotate through the transmission belt, the crank wheel drives the external rod and the internal rod to slide inside the conversion wheel, the external rod and the internal rod drive the external interface and the internal interface to slide inside the conversion wheel, and will not affect the rotation of the conversion wheel. When the gear rod is not engaged with the gear, the knob is turned, the knob drives the worm to rotate, the worm drives the worm wheel to rotate, the worm wheel drives the conversion wheel to rotate through the transmission belt, the conversion wheel drives the external interface and the internal interface to rotate, and the corresponding interface is adjusted by observing the indicator plate on the outside of the shell. After the adjustment is completed, the knob is clamped in the locking groove again, at this time, the knob drives the gear rod to reset, the gear rod drives the gear to reverse, the gear drives the crank wheel to reverse, the crank wheel makes the external interface and the internal interface slide to the outside of the conversion wheel, the external interface slides to the outside of the shell, and the internal interface is plugged with the internal joint, ensuring that only one interface needs to be opened on the device, thereby achieving the effect of being able to switch multiple interfaces, saving installation space, and being easy to use.

[0014] 2. The relay protection information transmission device for multi-compatible interfaces, by pulling the knob away from the locking slot, the knob drives the gear rod to move, the gear rod drives the gear to rotate, the gear drives the crank wheel to rotate through the transmission belt, the crank wheel drives the external rod and the internal rod to slide toward the inside of the conversion wheel, the external rod and the internal rod drive the external interface and the internal interface to slide toward the inside of the conversion wheel, at this time the baffle door swings back under the action of the internal spring, the baffle door closes the outer shell, ensures that the interface will not be contaminated when not in use, thereby achieving the effect of preventing interface contamination.

[0015] 3. The relay protection information transmission device for multiple compatible interfaces drives the inner connecting rod to slide toward the outside of the conversion wheel through the reverse rotation of the crank wheel, and the inner connecting rod drives the sliding rod to slide toward the outside of the conversion wheel, and the sliding rod drives the inner interface to slide toward the outside of the conversion wheel. The inner interface is plugged into the inner joint. When the connection between the inner interface and the outer interface is too loose, the sliding rod will not move relative to the inner connecting rod, and the detection switch contacts the inner connecting rod. When the device is connected, the detection switch lights up the prompt light, and the prompt light prompts that the inner interface is too loose and needs to be replaced or repaired, ensuring that the inner interface will not be difficult to detect damage in time because it is located inside the device, thereby ensuring stable information transmission, thereby achieving the effect of automatically detecting the tightness of the interface and stabilizing information transmission.
