Description

Technical Field

[0001] The invention relates to the technical field of data acquisition terminals, and in particular to a data acquisition terminal used in an energy-saving dispatching system of a thermal power plant. Background Art

[0002] In order to avoid excessive electricity consumption, most thermal power plants use energy-saving dispatching systems to assist in energy saving. However, the energy-saving dispatching system requires the composition and supply of a variety of equipment to operate normally, among which the data acquisition terminal is a part of the energy-saving dispatching system.

[0003] However, as far as the current traditional data acquisition terminals are concerned, in order to ensure safety, most of the existing data acquisition terminals require the circuit to be cut off before the terminal box can be opened for maintenance. However, it is inevitable that some maintenance personnel will open the box for maintenance without disconnecting the power for their own convenience. The risk of accidents during the maintenance process is relatively high, and it is impossible to forcibly cut off the power when opening the box through structural improvements.

[0029] Beneficial Effects

[0030] According to the data acquisition terminal of each embodiment of the present invention, compared with the traditional data acquisition terminal, the thumb presses the button to drive the sliding rod and the pressure block to move forward, so that the pressure block drives the limit block to shrink into the shrinkage groove A under the action of the force groove, so that the limit block is separated from the limit groove, and there is no fixed connection between the connecting rod and the connecting tube, which is convenient for separating the protective cover plate from the terminal box, and is more time-saving and labor-saving than traditional bolt locking and disassembly.

[0031] In addition, by pulling out the protective cover forward and moving it forward along the guide column, during the movement, the protective cover squeezes the inclined surface of the trigger block A, causing it to be forced to shrink toward the inside of the contraction groove B, causing the trigger block A to push the inclined surface of the trigger block B, causing the trigger block B to be forced to drive the cross plate and the trigger sheet to move backward, causing the trigger sheet to be forced to push the inclined surface of the force-bearing sheet backward, causing the force-bearing sheet to be forced to drive the secondary conductive cylinder to move outward and separate from the main conductive cylinder, thereby separating the electrical copper column A from the electrical copper column B, and then when the protective cover is opened, the electrical connection between the terminal module and the outside world can be forcibly cut off, avoiding the occurrence of safety accidents caused by maintenance personnel who are seeking their own convenience and directly repairing without turning off the power, causing huge losses and harm to the maintenance personnel and the thermal power plant.

[0032] In addition, after the protective cover is separated from the terminal box, the push block will recover under the action of spring A and will no longer push the force block, so that the slide plate can drive the magnet A to move inward under the action of spring D, so that the inner end of the magnet A is parallel to the inner end of the release push rod, so that the magnet A can approach the magnet B, and then when the secondary conductive cylinder moves outward, the magnet A can be attracted to the magnet B, so that the wiring A and the wiring B remain in a separated state, which is convenient for the staff to cut off the power for maintenance.

[0033] Moreover, the present invention forcibly cuts off the power when the protective cover is pulled out through structural improvements, thereby ensuring safety during maintenance. In addition, the power is automatically cut off when the protective cover is pulled out, eliminating the need for manual power-off work, eliminating the step of manual power-off and improving maintenance efficiency.

[0068] In another embodiment, a protective rubber pad can be provided on the front side of the pressing plate 208 , and the provision of the protective rubber pad can ensure the comfort level when the operator's fingers touch the pressing plate 208 .

[0069] In addition, according to an embodiment of the present invention, Figure 3 and Figure 6 As shown, force blocks 301 are slidably installed on the left and right sides of the support frame 3, and the front side of the inner end of the force block 301 is inclined; a vertical rod 302 is arranged on the outer side of the force block 301; a slide plate 303 is slidably installed inside the support frame 3, and the inner side of the slide plate 303 is connected to the outer end of the vertical rod 302; one end of a spring D304 is embedded and installed on the outer side of the slide plate 303, and the other end of the spring D304 is embedded and installed on the inner side of the support frame 3; release push rods 305 are arranged on the upper and lower sides of the inner side of the support frame 3; a magnetic attraction A306 is arranged on the inner side of the slide plate 303, and when the protective cover plate 2 is detached from the terminal box 1, the push block 106 will not push the force block 301 , so that it no longer drives the vertical rod 302 to push the slide plate 303 outward, so that the slide plate 303 can move inward under the action of the spring D304, so that the position of the magnetic attraction A306 is close to the magnetic attraction B504. When the protective cover 2 is docked with the terminal box 1, the push block 106 pushes the inclined surface of the force-bearing block 301, so that the force-bearing block 301 is affected by the push and drives the vertical rod 302 and the slide plate 303 to move outward, so that the magnetic attraction A306 moves outward and separates from the magnetic attraction B504. If the magnetic attraction B504 moves outward with the magnetic attraction A306 under the influence of the magnetic attraction, the release push rod 305 will push and limit the magnetic attraction B504, thereby ensuring that the magnetic attraction B504 is separated from the magnetic attraction A306.

[0070] In addition, according to an embodiment of the present invention, Figure 4As shown, a contraction groove B401 is provided on the circumferential outer wall of the guide column 4; a trigger block A402 is slidably installed inside the contraction groove B401; both sides of the trigger block A402 are inclined; one end of a spring E403 is embedded and installed on the inner side of the trigger block A402, and the other end of the spring E403 is embedded and installed on the inner side of the contraction groove B401; a transverse groove 404 is provided inside the guide column 4; a trigger block B405 is slidably installed inside the transverse groove 404, and the front end of the trigger block B405 is inclined; one end of a spring F406 is embedded and installed on the rear side of the transverse groove 404, and the other end of the spring F406 is embedded and installed The rear side of the trigger block B405; a transverse plate 407 is provided at the inner end of the rear side of the trigger block B405; a trigger plate 408 is fixedly installed at the rear end of the transverse plate 407, and the trigger plate 408 is a rectangular structure. By pulling out the protective cover plate 2 forward, during the pulling out process, the protective cover plate 2 will push the inclined surface of the trigger block A402, so that the trigger block A402 will shrink into the inside of the shrinkage groove B401 due to the influence of the pushing. During the shrinkage process, the trigger block A402 will push the inclined surface of the trigger block B405, so that the trigger block B405 will be affected by the pushing and drive the transverse plate 407 and the trigger plate 408 to move backward, so that the trigger plate 408 pushes the inclined surface of the force-bearing plate 505.

[0071] In addition, according to an embodiment of the present invention, Figure 2 , Figure 4 and Figure 7 As shown, the outer end of the main conductive cylinder 5 is provided with a support rod 501; the support rod 501 is slidably mounted with a secondary conductive cylinder 502; the interior of the main conductive cylinder 5 is provided with an electrical copper column A506; the inner side of the electrical copper column A506 is provided with a wiring A507, and the other end of the wiring A507 is electrically connected to the terminal module 6; the interior of the main conductive cylinder 5 is provided with an electrical copper column B508, and the outer side of the electrical copper column B508 is provided with a wiring B509; one end of a spring G503 is embedded and mounted on the inner side of the secondary conductive cylinder 502, and the other end of the spring G503 is embedded and mounted on the main conductive cylinder 502.

The trigger sheet 408 pushes the inclined surface of the force-bearing sheet 505, so that the force-bearing sheet 505 starts to drive the auxiliary conductive cylinder 502 to move outward under the influence of the push, so that the auxiliary conductive cylinder 502 drives the electrical copper column B508 to move outward and separate from the electrical copper column A506, so that there is no electricity between the wiring A507 and the wiring B509, and the power supply of the terminal module 6 is cut off, which is convenient for maintenance work.

[0072] The specific usage and function of this embodiment: when in use, first install the terminal box 1 in a suitable position, and then electrically connect the other end of the wiring B509 to a suitable external line, so as to provide power transmission to the terminal module 6, so that the terminal module 6 cooperates with other equipment to serve the dispatching system;

[0073] When the terminal module 6 needs to be repaired, the pressing plate 208 is manually pressed, so that the pressing plate 208 is pressed to drive the slide bar 206 and the pressing block 207 to move forward, so that the inclined surface of the pressing block 207 pushes the inclined surface of the force-bearing groove 205, so that the force-bearing groove 205 is affected by the pushing and drives the limit block 203 to move inward and shrink into the inside of the shrinkage groove A202, so that the limit block 203 is separated from the limit groove 102, and the limit fixation of the protective cover plate 2 is cancelled;

[0074] The thumb is used to continuously press the pressing plate 208 to pull the protective cover plate 2 forward. During the pulling process, the protective cover plate 2 will push the inclined surface of the trigger block A402, so that the trigger block A402 is affected by the pushing and shrinks into the shrinkage groove B401. During the shrinkage process, the trigger block A402 will push the inclined surface of the trigger block B405, so that the trigger block B405 is affected by the pushing and drives the cross plate 407 and the trigger sheet 408 to move backward, so that the trigger sheet 408 pushes the inclined surface of the force-bearing sheet 505, so that the force-bearing sheet 505 starts to drive the auxiliary conductive tube 502 to move outward under the influence of the pushing, so that the auxiliary conductive tube 502 drives the electrical copper column B508 outward. Move and separate the electrical copper column A506, so that there is no electricity between the wiring A507 and the wiring B509, and the power supply of the terminal module 6 is cut off. When the protective cover 2 is separated from the terminal box 1, the push block 106 will not push the force block 301, so that it will no longer drive the vertical rod 302 to push the slide plate 303 outward, so that the slide plate 303 can move inward under the action of the spring D304, so that the position of the magnetic attraction A306 is close to the magnetic attraction B504, so that when the secondary conductive tube 502 moves outward, the magnetic attraction A306 can be attracted to the magnetic attraction B504, so that the wiring A507 and the wiring B509 remain de-energized, and finally the terminal module 6 can be inspected and repaired.

[0075] Finally, it should be noted that when describing the position of each component and the matching relationship between them, the present invention usually takes one / a pair of components as an example. However, those skilled in the art should understand that such position, matching relationship, etc. are also applicable to other components / other pairs of components.
