[0035] Example 1

[0036] Reference Figure 1 , Figure 3 to Figure 5 , Fig.10 and Fig.11 , which is the first embodiment of the present invention, provides an electric power safety protection device for a power plant, including a protection component 100, including a protection shell 101 with a receiving cavity H and an opening on one side, and a protection cover 102 arranged on the top of the protection shell 101; the surface of the protection shell 101 is evenly provided with heat dissipation holes to provide basic heat dissipation for the power equipment, and a box door 103 is movably provided on the open side of the protection shell 101, a bracket component 200 for installing the power equipment is provided in the receiving cavity H, and an opening and closing component 300 for controlling the opening and closing of the box door 103 is also provided in the receiving cavity H.

[0037] Furthermore, the bracket assembly 200 includes two first guide rails 201 arranged in parallel at the bottom of the accommodating cavity H and extending toward the opening side of the protective shell 101, and first slide seats 202 are slidably arranged on the two first guide rails 201, and an equipment support plate 203 is connected between the two first slide seats 202 by bolts.

[0038] Furthermore, support frames 204 are provided at the four corners of the top of the equipment support plate 203. The support frames 204 are made of insulating material. One end of the support frame 204 is connected to the support plate by bolts, and the other end of the support frame 204 is provided with an insulating pad 205. The insulating pad 205 is in contact with the bottom of the power equipment. The support frame 204 supports the power equipment, and the insulating properties of the support frame 204 and the insulating pad 205 are used to prevent leakage of the power equipment from being transmitted to the protective shell 101.

[0039] Specifically, the power equipment is placed above the equipment support plate 203 and supported by the support frame 204. The support frame 204 is made of insulating material to prevent leakage of the power equipment from being transmitted to the protective shell 101, thereby ensuring power safety. The equipment support plate 203 can slide along the first guide rail 201 through the first slide seat 202, thereby driving the power equipment to move forward and backward, changing the front and rear position of the power equipment in the accommodating chamber H. During maintenance or operation, the power equipment can be adjusted to the front side of the accommodating chamber H, making it more convenient for the operator to operate.

[0040] Furthermore, the opening and closing assembly 300 includes a support plate 301 arranged at the top of the accommodating cavity H, a connecting seat 302 connected to the inner top end of the box door 103 by bolts, and an opening and closing control link member 303 arranged between the support plate 301 and the connecting seat 302; the opening and closing control link member 303 includes a positioning column 303a and a movable shaft 303b vertically arranged at the bottom of the support plate 301, an adjusting link 303c movably connected to the positioning column 303a, and a control bent rod 303d fixed to the movable shaft 303b; one end of the adjusting link 303c away from the positioning column 303a is hinged to one end of the connecting seat 302, and one end of the control bent rod 303d away from the movable shaft 303b is hinged to the other end of the connecting seat 302.

[0041] Specifically, when the door 103 is in the open state, the adjusting link 303c is in a horizontal and vertical state with the opening side of the protective shell 101, and in the process of closing the door 103, the control crankshaft 303d rotates clockwise with the movable shaft 303b as the center, and the adjusting link 303c rotates clockwise with the positioning column 303a as the center, and when the adjusting link 303c rotates to a vertical state with the opening side of the protective shell 101, the door 103 is closed; and in the process of opening the door 103, the control crankshaft 303d and the adjusting link 303c both rotate counterclockwise.

[0042] The box door 103 is opened and closed by using double rods (adjusting connecting rod 303c and controlling bent rod 303d). When viewed from above, the box door 103, adjusting connecting rod 303c and controlling bent rod 303d form a stable triangle. After the box door 103 is opened and closed, it is kept in a state parallel to the opposite side panel of the protective shell 101. When the box door 103 is closed, it fully covers the opening of the protective shell 101, and is stably placed on one side of the power equipment after opening.

[0043] Furthermore, a lock installation groove 103a and an axial hole passing through the lock installation groove 103a are provided in the middle of one side of the box door 103, and a snap-on lock piece 105 is provided in the lock installation groove 103a. A lock shaft 106 is movably provided in the axial hole, and one end of the lock shaft 106 extends to the outside of the box door 103 and is fixedly connected to a rotary handle 107, and the other end of the lock shaft 106 extends into the lock installation groove 103a and is fixedly connected to the snap-on lock piece 105; a locking groove 101b is provided at the protective shell 101 corresponding to the lock installation groove 103a, and the snap-on lock piece 105 can be rotated so that one end of it is inserted into the locking groove 101b.

[0044] Specifically, the rotary handle 107 facilitates pulling the box door 103. When the box door 103 needs to be opened, the rotary handle 107 is turned to move the part of the latching lock piece 105 inserted into the locking groove 101b out and disengage it from the locking groove 101b. After that, the box door 103 can be opened without being locked; and when the box door 103 is closed, the rotary handle 107 can be turned to drive the latching lock piece 105 to rotate synchronously and insert one end of it into the locking groove 101b. Both ends of the latching lock piece 105 are provided with chamfers. With the guidance of the chamfered inclined surface, the latching lock piece 105 can be more smoothly latched into the locking groove 101b, thereby locking the box door 103.

[0045] Example 2

[0046] Reference Figure 2 to Figure 6 and Figures 9 to 12 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that an opening and closing gear 304 is coaxially sleeved on the outside of the movable shaft 303b, a rack 305 is meshed on one side of the opening and closing gear 304, the rack 305 is arranged parallel to the first guide rail 201, and a support column 206 is provided between the rack 305 and the equipment support plate 203.

[0047] Furthermore, a wire taking-up cavity M is provided between the protective shell 101 and the protective cover 102, and a cable follower assembly 400 is provided in the wire taking-up cavity M, and the cable follower assembly 400 includes a second guide rail 401, a follower plate 403, a wire guard plate 404, and a wire reel 405; there are two second guide rails 401 and both are arranged in parallel with the first guide rail 201, and second slide seats 402 are slidably provided on the two second guide rails 401, and the follower plate 403 is connected between the two second slide seats 402 by bolts, and the follower plate 403 can slide along the second guide rail 401 with the help of the second slide seat 402; the follower plate 403 is provided with a through groove consistent with the outer contour of the wire guard plate 404, and the wire guard plate 404 is provided with a threading hole; both ends of the wire reel 405 are open and connected to the protective cover 102 through a suspension rod, and the rear end of the protective cover 102 is provided with a wire entry hole 102a directly opposite to the wire reel 405.

[0048] Furthermore, a wire inlet groove 101a is provided on the top plate of the protective shell 101 corresponding to the follower plate 403, and a connecting bent frame 406 is provided on one side of the follower plate 403. One end of the connecting bent frame 406 away from the follower plate 403 passes through the wire inlet groove 101a and is connected to the rack 305 by bolts.

[0049] Furthermore, a cable plug 407 is provided in the wire threading hole to fix and protect the cable. A through wiring groove 407a is provided on the cable plug 407. The number of wire threading holes of the wire guard plate 404 and the wiring groove 407a of the cable plug 407 is reasonably set according to the number of wiring strips. One end of the cable can pass through the wire entry hole 102a, the wiring drum 405, the wiring groove 407a of the cable plug 407, and the wire entry groove 101a in sequence and be connected to the power equipment.

[0050] Specifically, since the electric equipment will inevitably cause the cables connected to the electric equipment to be pulled forward and backward when moving forward and backward, the follower plate 403 is driven to move forward and backward through the sliding guidance of the second guide rail 401 and the second slide seat 402, so that the follower plate 403 can move forward and backward with the pulling of the cable.

[0051] In summary, with the help of the support column 206, the rack 305 is connected to the equipment support plate 203; with the help of the connecting bend 406, the rack 305 is connected to the follower plate 403; when the rack 305 moves forward and backward, it can drive the equipment support plate 203 and the power equipment, as well as the follower plate 403 and the cable to move forward and backward synchronously. The rack 305 is meshed with the opening and closing gear 304. During the opening process of the box door 103, the box door 103 rotates counterclockwise to open, driving the opening and closing gear 304 to rotate counterclockwise synchronously, thereby driving the rack 305 to move forward toward the opening side of the protective shell 101, thereby automatically driving the power equipment and the cable to move forward and backward synchronously, which is convenient for the maintenance or operation of the power equipment. There is no need for maintenance or operating personnel to lean into the accommodating chamber H of the protective shell 101, reducing the risk of accidental electric shock; and during the closing process of the box door 103, the opening and closing gear 304 rotates clockwise, driving the rack 305 to move backward, even if the power equipment moves to a position near the middle of the accommodating chamber H, the protective shell 101 provides better protection for the power equipment.

[0052] The remaining structures are the same as those of Example 1.

[0053] Example 3

[0054] Reference Figure 2 , Figure 5 , Figure 7 to Figure 9 and Figure 13-14, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: an elevated platform 104 is provided at the bottom of the protective shell 101, and the elevated platform 104 is provided with an installation cavity N with a top opening, and an air inlet that passes through the installation cavity N is provided on one side of the elevated platform 104. A heat dissipation component 500 is provided in the installation cavity N, and the heat dissipation component 500 includes a heat dissipation fan 501 slidably installed with the elevated platform 104, a dust filter 502 arranged at the bottom of the heat dissipation fan 501, and a protective net 503 detachably installed at the air inlet.

[0055] Specifically, the elevated platform 104 raises the protective shell 101 as a whole to prevent surface moisture from entering the accommodating cavity H and causing damage to the power equipment; the cooling fan 501 cooperates with the air inlet to suck external air into the accommodating cavity H to dissipate heat for the power equipment in the accommodating cavity H; the dust filter 502 cooperates with the protective net 503 to play a protective role, reduce the amount of dust in the accommodating cavity H, and prevent snakes, insects, rats and ants from entering the installation cavity N.

[0056] Furthermore, a pull-out opening adapted to the heat dissipation fan 501 is provided on one side of the elevated platform 104, and an ash discharge opening 104a is provided below the pull-out opening. A guide groove plate 504 is provided on the inner wall of one side of the installation cavity N corresponding to the ash discharge opening 104a, and side supports 504a are provided on both sides of the guide groove plate 504.

A telescopic rod 506 is provided between the dust removal brush 505 and the side support 504a, and a spring 507 is sleeved on the outside of the telescopic rod 506.

[0057] Specifically, the spring 507 pushes the telescopic rod 506 to extend, so that the bristles on the top of the dust removal brush 505 can contact the lower side of the dust filter 502. During cleaning, the cooling fan 501 is pulled back and forth from the pull-out port several times, and the bristles on the top of the dust removal brush 505 clean the dust filter 502. The falling dust slides along the guide groove plate 504 and is finally discharged from the dust discharge port 104a.

[0058] Furthermore, a through blowing groove 203a is provided in the middle of the equipment support plate 203, and guide shafts 508 are arranged equidistantly in the blowing groove 203a.
