[0046] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0047] Example, see Figures 1 to 9 , which is the first embodiment of the present invention, and provides a coal-fired unit index assessment management device, which includes a power distribution cabinet 1, an assembly frame 2 is fixedly installed on the outside of the power distribution cabinet 1, and a plurality of heat dissipation components 3 for cooling the power distribution cabinet 1 are arranged on the assembly frame 2;

[0048] The heat dissipation component 3 includes a self-locking motor 301 fixed inside the assembly frame 2, a steering rod 302 is fixedly installed at the output end of the self-locking motor 301, and the other end of the steering rod 302 is installed on the surface of the assembly frame 2 through a bearing, a fixing plate 303 is fixedly installed on the outside of the steering rod 302, an insulating layer 304 is fixedly installed on the front surface of the fixing plate 303, a fireproof layer 305 is fixedly installed on the back of the fixing plate 303, a first positive magnet 306 is fixedly installed on both sides of the fixing plate 303, and two negative magnets 307 corresponding to the first positive magnet 306 are arranged on the inner wall of the assembly frame 2, and the first positive magnet 306 is connected to the negative magnet 307 by magnetic attraction, so that the fixing plate 303 and the assembly frame 2 are effectively combined;

[0049] When the power distribution cabinet 1 is in use, the heat dissipation component 3 outside the assembly frame 2 on the power distribution cabinet 1 can be started, and the self-locking motor 301 on the heat dissipation component 3 can be powered on to start operation. The self-locking motor 301 will drive the steering rod 302 to rotate rapidly, and the rapidly rotating steering rod 302 will drive the fixing plate 303 to rotate. At this time, as the multiple heat dissipation components 3 rotate outside the power distribution cabinet 1, they can continuously drive the rapid flow of the airflow outside the power distribution cabinet 1, thereby realizing the effective extraction of the hot airflow, thereby playing a function of quickly dissipating the heat of the power distribution cabinet 1;

[0050] The self-locking motor 301 can be powered on to drive the retaining plate 303 on the steering rod 302 to close the outside of the assembly frame 2, so that the multiple heat dissipation components 3 can be used to close the outside of the assembly frame 2. At this time, the multiple heat dissipation components 3 can cooperate with the assembly frame 2 to form a box body with a top and four sides closed. In this way, during the transportation or placement of the distribution cabinet 1, the multiple heat dissipation components 3 are used in conjunction with the assembly frame 2 to achieve external safety protection of the distribution cabinet 1, avoiding the lack of protection when the distribution cabinet 1 is hit by the outside, thereby improving the safety of the distribution cabinet 1.

[0051] When sparks appear inside the distribution cabinet 1, the self-locking motor 301 can be started to drive the fixing plate 303 on the steering rod 302 to rotate. At this time, the surface of the fixing plate 303 with the fireproof layer 305 faces the outside of the distribution cabinet 1, and the insulating layer 304 on the fixing plate 303 faces the outside of the assembly frame 2, so that the distribution cabinet 1 is in a closed environment. In this way, when a fire source appears inside the distribution cabinet 1, it will not be able to burn effectively due to insufficient oxygen outside the distribution cabinet 1. At the same time, the insulating layer 304 can prevent the distribution cabinet 1 from causing a safety threat due to leakage.

[0052] A retaining groove 4 for passing the connection line on the power distribution cabinet 1 is provided at the bottom of the assembly frame 2, a sealing strip 5 is fixedly installed on the bottom outer wall of the assembly frame 2, and an upwardly inclined support component 6 is provided on the surface of the bottom of the inner cavity of the retaining groove 4, wherein the support component 6 is used to support the line on the power distribution cabinet 1;

[0053] The support assembly 6 includes a merging groove 601 provided at the bottom of the retaining groove 4, a support rod 602 is fixedly installed in the inner cavity of the merging groove 601, a closing cover 603 is movably installed at one end of the support rod 602, a return spring 604 is fixedly installed at the bottom of the closing cover 603, and the bottom of the return spring 604 is fixed to the bottom of the inner cavity of the merging groove 601;

[0054] The bottom of the assembly frame 2 can prevent the ground liquid from flowing to the distribution cabinet 1 through the sealing strip 5, thereby preventing the liquid from interfering with the normal operation of the distribution cabinet 1. At the same time, since the distribution cabinet 1 will be installed with lines connected to external equipment, these lines can be inserted into the retention groove 4 at this time, and the surface of the line will also be supported by the closing cover 603 on the support assembly 6, and the closing cover 603 is pulled upward to the outside of the assembly frame 2 by the pull of the return spring 604, so that one end of the line will not contact the ground. At this time, when liquid contacts the line, the inclined line will not conduct the liquid, thereby preventing the liquid from flowing along the line to the distribution cabinet 1, thereby improving the waterproof effect of the distribution cabinet 1;

[0055] When the distribution cabinet 1 is not in use, the lines on the distribution cabinet 1 can be drawn into the space inside the assembly frame 2. At this time, the retaining groove 4 will be closed by the return spring 604 pulling the closing cover 603 on the support rod 602. This ensures the closedness of the outside of the distribution cabinet 1, which is more conducive to transportation and storage and avoids the inconvenience of line retraction.

[0056] The inner wall of the assembly frame 2 is provided with a plurality of groups of water absorbing components 7 for waterproofing, and an alarm component 8 is provided on the surface of each group of water absorbing components 7;

[0057] The water absorption component 7 includes a steering groove 701 opened on the inner wall of the assembly frame 2, a movable rod 702 is fixedly installed in the inner cavity of the steering groove 701, a closed net 703 is movably installed outside the movable rod 702, one side of the closed net 703 is fixed to the inner surface of the assembly frame 2 by bolts, a guide rod 704 is also fixedly installed on the inner wall of the assembly frame 2, a merging ring 705 is fixedly installed on the surface of the guide rod 704, a water absorption sponge 706 is placed on the surface of the guide rod 704, and the top surface of the water absorption sponge 706 is in contact with the surface of the closed net 703, and the surface of the merging ring 705 is installed with the outside of the alarm component 8;

[0058] The alarm component 8 includes a second positive magnet 801 embedded in the surface of the merging ring 705, a hanging bracket 802 is fixedly installed on the surface of the power distribution cabinet 1, an early warning bell 803 is movably installed at the bottom of the hanging bracket 802, a limit frame 804 is also fixedly installed at the bottom of the limit frame 804, a hanging rope 805 is fixedly installed at the bottom of the inner cavity of the limit frame 804, a striking rod 806 is fixedly installed at the bottom of the hanging rope 805, and a third positive magnet 807 is embedded at one end of the striking rod 806 facing the merging ring 705;

[0059] When liquid appears inside the assembly frame 2, the water-absorbing sponge 706 on the water-absorbing component 7 can be used to absorb the liquid. At this time, as the liquid absorbed by the water-absorbing sponge 706 gradually increases, the water-absorbing sponge 706 will gradually increase in size. At this time, the water-absorbing sponge 706 can be used to further waterproof the bottom of the distribution cabinet 1;

[0060] When the water-absorbing sponge 706 expands, it will push the merging ring 705 on the guide rod 704 to move toward the position of the alarm component 8, and then the second positive magnet 801 on the merging ring 705 will repel the third positive magnet 807 on the impact rod 806. Under the influence of the repulsive force, the impact rod 806 will cooperate with the hanging rope 805 to impact the warning bell 803 through the position limited by the limit frame 804. The impacted warning bell 803 will emit an alarm sound, which can effectively remind the passing personnel that there is a problem of liquid flow around the power distribution cabinet 1, and make timely responses, thereby more quickly waterproofing. In this process, no electric energy is required, and energy loss is low;

[0061] When the water-absorbing sponge 706 is to be replaced, the closed net 703 on the movable rod 702 can be opened, and then the expanded water-absorbing sponge 706 can be taken out for replacement.

[0062] A dustproof component 9 is disposed on the outer wall of the power distribution cabinet 1 , and the dustproof component 9 is disposed around the outside of the power distribution cabinet 1 .

[0063] The dustproof component 9 includes an isolation frame 901 fixedly mounted on the top of the power distribution cabinet 1, a plurality of groups of screen members 902 for preventing dust are arranged on the surface of the isolation frame 901, and a plurality of groups of dust collecting members 903 for collecting impurities are arranged on the bottom of the isolation frame 901;

[0065] As a preferred solution of the coal-fired unit index assessment management device of the present invention, the dust collecting member 903 includes a positioning groove 9031 provided on the surface of the screen door 9022, and a storage box 9032 for collecting impurities is placed inside the positioning groove 9031, wherein the opening of the storage box 9032 is inclined upward, and the surface of the isolation frame 901 on which the storage box 9032 is installed is also inclined in the same manner;

[0066] When the heat dissipation component 3 is in operation, the external airflow will be brought into contact with the surface of the power distribution cabinet 1. At this time, the screen member 902 on the isolation frame 901 can be used to block dust and other impurities in the airflow. At this time, dust and other impurities can be blocked by the screen door 9022, thereby preventing dust and impurities from directly contacting the surface of the power distribution cabinet 1, thereby affecting the heat dissipation of the power distribution cabinet 1, and once again improving the heat dissipation effect of the power distribution cabinet 1;

[0067] The dust and other impurities blocked by the screen door 9022 will be guided to the storage box 9032 on the dust collecting member 903. The storage box 9032 can be used to collect dust and other impurities in a centralized manner, which facilitates subsequent cleaning work.

[0068] When the staff needs to open the distribution cabinet 1, they hold the handle 9024 on the surface of the screen door 9022, and then pull the screen door 9022 to open the external obstacles of the distribution cabinet 1, thereby not interfering with the operation of the distribution cabinet 1.
