[0015] The present invention provides a power control cabinet device with a protective structure, which has the following beneficial effects: 1. The present invention is provided with an outer cabinet device, and an explosion-proof cabinet body with an integrated structure can provide effective external protection for the entire device. The stabilizing frame horizontally erected inside the outer cabinet body can improve the internal support of the overall structure when the explosion-proof cabinet body is impacted in the horizontal direction. At the same time, the internal energy-absorbing column arranged between the explosion-proof cabinet body and the inner cabinet device can absorb the potential energy of the impact in the external horizontal direction to the greatest extent and alleviate it, thereby protecting the inner cabinet device and the electrical equipment assembled therein, and at the same time, it can also play a role of structural support for the inner cabinet device. The structural application of the stabilizing seat can fix the entire outer cabinet device on the ground, thereby ensuring that the entire device can stand stably on the ground and avoid the problem of tipping. In addition, the use of the air intake network pipe and the ventilation network pipe can prevent foreign matter from entering the interior of the outer cabinet device without affecting the ventilation and air exchange inside the entire outer cabinet device, protect the internal electrical equipment from the influence of foreign matter, and play a role of filtering protection.
[0016] 2. The present invention is provided with an outer door device, which forms a complete protective structure with the explosion-proof cabinet through an explosion-proof door body having the same internal structure as the explosion-proof cabinet, and cooperates with the explosion-proof cabinet to fully protect the internal electrical equipment and minimize the damage to the internal structure caused by external impact. At the same time, the sealing strip arranged at the joint of the explosion-proof cabinet and the explosion-proof door body can avoid the situation of external liquid penetration when the outer cabinet device and the outer door device are closed to the greatest extent, thereby improving the structural sealing of the connection between the two. On the other hand, when the entire outer door device is structurally closed with the outer cabinet device through a hinge, the inner energy absorption plate can be placed just between the explosion-proof door body and the inner cabinet device, so that the device has good energy absorption and buffering protection in the front direction to protect the electrical equipment from damage.
[0017] 3. The present invention is provided with a flame retardant device. Considering that after a number of electrical devices are assembled inside the entire device, during operation, if a short circuit occurs due to internal or external factors and the circuit breaker cannot function effectively, an open flame or the like may occur or has occurred, by using the induction valve tube and utilizing the internal voltage sensor and other structures, after detecting the voltage abnormality, the control valve will be started, and the inert gas pre-stored in the inert gas storage tank will be filled into the interior of the entire outer cabinet device at the fastest speed through the nozzle through the connecting pipe, so as to effectively curb the possible danger and avoid the occurrence of open flames or the like, or even the aggravation of the problem.
[0018] 4. The present invention is provided with an inner cabinet device. Since the entire inner protection box is structurally connected to each other by means of pulley blocks symmetrically arranged on the upper and lower sides and telescopic guide rails installed on the stabilizing frame, the entire inner cabinet device can move forward and backward in the Z-axis horizontally along the telescopic guide rails under the rolling of the pulley block. Therefore, when it is necessary to assemble electrical equipment and perform maintenance on the installed electrical equipment, the entire electrical equipment can be pulled out from the inside of the outer cabinet device as a whole to facilitate the operation of the operator. At the same time, the energy-absorbing column arranged between the inner protection box and the explosion-proof cabinet body can further improve the structural protection provided by the outer cabinet device and the outer door device to ensure the operational safety of the electrical equipment. On the other hand, the assembly frame is horizontally mounted on the support frame by means of an adjustment frame. The structural adjustment and disassembly between the adjustment frame and the support frame allows the assembly frame to move up and down in the vertical direction along the surface of the support frame to adapt to the installation of electrical equipment of different sizes and structures. At the same time, different numbers of assembly frames can be set up as needed to reasonably allocate the internal space of the entire inner protection box and make a reasonable fixed installation for the electrical equipment.
[0019] 5. The present invention is provided with a cooling device and a ventilation device. Considering that the types and quantities of the electrical equipment inside the entire outer cabinet device are different due to different usage needs, and the power of each electrical equipment is also different, when many devices are operated at the same time, a high heat will be generated, causing the temperature inside the outer cabinet device to rise sharply, and the electrical equipment cannot operate normally. The air transported from the outside by the air inlet pipe is cooled by the cooler, and the cold air is quickly blown into the interior of the entire explosion-proof cabinet by the centrifugal fan, thereby playing an effective role in cooling and heat dissipation. In addition, since the entire inner cabinet device is fixed to the top of the interior of the explosion-proof cabinet by a shock-absorbing frame and a suspension pile, the shock-absorbing frame and the suspension pile can be used to To the greatest extent possible, the vibration or jitter generated by the operation of the cooler and centrifugal fan can be absorbed and alleviated to avoid affecting other electrical equipment. Due to the operation of the cooling device, the air inside the outer cabinet device will condense while cooling. In order to avoid the condensed water vapor from affecting the electrical equipment, the dehumidifier and filter fan are used to effectively filter the water vapor in the air and store it inside the filter box for subsequent centralized processing. At the same time, the filter fan can exchange air between the inside and outside of the entire outer cabinet device, filter the air during the gas exchange process while ensuring effective air circulation, reduce the entry of dust and impurities, and thus reduce the impact on electrical equipment.

The stabilizing frame 106 horizontally arranged inside the explosion-proof cabinet 101 can improve the internal support of the overall structure when the explosion-proof cabinet 101 is subjected to horizontal impact. At the same time, the internal energy absorption plate 204 arranged between the explosion-proof cabinet 101 and the inner cabinet device 4 can absorb the potential energy of the external horizontal impact to the greatest extent. At the same time, the structural application of the stabilizing seat 102 can fix the entire outer cabinet device 1 on the ground. In addition, the use of the air intake network pipe 103 and the ventilation network pipe 104 can prevent foreign objects from entering the interior of the outer cabinet device 1 without affecting the ventilation and air exchange inside the entire outer cabinet device 1, thereby protecting the internal electrical equipment from the influence of foreign objects.

The sealing strip 203 and the outer cabinet device 1 have a close docking structure with each other, and the explosion-proof door body 201 with the same internal structure as the explosion-proof cabinet body 101 cooperates with the explosion-proof cabinet body 101 to form a complete protective structure. At the same time, the sealing strip 203 arranged at the joint of the explosion-proof cabinet body 101 and the explosion-proof door body 201 can avoid the external liquid penetration when the outer cabinet device 1 and the outer door device 2 are closed to the greatest extent, and improve the structural sealing of the connection between the two. On the other hand, when the entire outer door device 2 is structurally closed with the outer cabinet device 1 through the hinge 205, the inner energy absorption plate 204 can be placed just between the explosion-proof door body 201 and the inner cabinet device 4, so that the device has good energy absorption and buffering protection in the front direction.
[0026] like Figure 1 , Figure 3 , Figure 6 , Figure 7 and Fig. 9As shown, the inner cabinet device 4 includes an inner protection box 401, a pulley block 402, a docking groove 403, a support frame 404, an adjustment frame 405 and an assembly frame 406.

The inner wall of the inner protection box 401 is vertically installed with a support frame 404, and the side surface of the support frame 404 is connected to the adjustment frame 405, and the adjustment frame 405 is away from the support frame One side of 404 is horizontally connected to an assembly frame 406, the pulley block 402 is symmetrically arranged up and down with the horizontal central axis of the inner protection box 401 as the symmetry axis, and the pulley block 402 is slidably connected to the telescopic guide rail 107, the docking groove 403 and the support frame 404 are both symmetrically arranged left and right with the vertical central axis of the inner protection box 401 as the symmetry axis, the adjustment frame 405 is symmetrically arranged left and right with the vertical central axis of the assembly frame 406 as the symmetry axis, and the adjustment frame 405 is fixedly connected to the assembly frame 406. The surface structure of the docking groove 403 and the connection of the energy absorbing column 105 match each other and are slidably connected to each other. By utilizing the pulley block 402 symmetrically arranged on the upper and lower sides and the telescopic guide rail 107 installed on the stabilizing frame 106, the entire inner cabinet device 4 can move forward and backward in the Z-axis horizontally along the telescopic guide rail 107 under the rolling of the pulley block 402.

[0027] like Figure 1 , Figure 8 and Fig.10As shown, the cooling device 5 includes a cooler 501, a shock absorbing frame 502, a suspension pile 503, an air inlet pipe 504 and a centrifugal fan 505. The shock absorbing frame 502 is installed on the top of the cooler 501, and the suspension pile 503 is set on the top of the shock absorbing frame 502. The left and right sides of the cooler 501 are connected to the air inlet pipe 504, and the bottom of the cooler 501 is connected to the centrifugal fan 505.

In addition, since the entire inner cabinet device 4 is fixed to the top of the interior of the explosion-proof cabinet 101 by the shock-absorbing frame 502 and the suspension pile 503, the vibration or jitter generated by the operation of the cooler 501 and the centrifugal fan 505 can be absorbed and alleviated to the greatest extent by the shock-absorbing frame 502 and the suspension pile 503.

At the same time, the filter fan 602 can exchange air between the interior and the outside of the entire outer cabinet device 1, which can reduce the entry of dust and impurities.
[0028] In summary, combined Figure 1-Figure 10 As shown, the working principle of the power control cabinet device with a protective structure is as follows: first, according to the use needs, the structural setting of the stabilizing seat 102 in the outer cabinet device 1 can be used to fix the entire control cabinet on the ground, so as to limit the position and ensure the stability of the entire device. When it is necessary to assemble a number of electrical equipment inside the inner cabinet device 4, first open the outer door device 2 on the front of the outer cabinet device 1 to display the entire inner cabinet device 4 in front of the operator, and then manually pull the entire inner cabinet device 4. At this time, the inner cabinet device 4 is horizontally translated along the surface of the telescopic guide rail 107 in the direction of the X-axis under the rolling of the pulley group 402 until it is moved out of the explosion-proof cabinet 101, thereby facilitating the assembly operation of the operator; Then, the number of assembly racks 406 installed on the surface of the support rack 404 and the relative layer distances between the assembly racks 406 in the vertical direction are adjusted by using the adjustment rack 405 according to the size and number of the electrical equipment. After the electrical equipment is installed inside the inner cabinet device 4, the entire inner cabinet device 4 is then moved along the telescopic guide rails 107 installed on the surface of the stabilizing rack 106 by using the pulley blocks 402 on the upper and lower sides of the inner protection box 401, and the structural reset is completed; When the entire inner cabinet device 4 moves from inside to outside and from outside to inside, the energy absorbing column 105 will slide along the docking groove 403 provided on the side surface of the inner protection box 401, which not only plays a role of structural guidance, but also plays a role of structural support when the entire inner cabinet device 4 is stored in the center of the explosion-proof cabinet 101; After that, the hinge 205 can be used to close and dock the outer cabinet device 1 and the outer door device 2, and the sealing strip 203 is tightly attached between the explosion-proof door body 201 and the explosion-proof cabinet body 101. At the same time, when the explosion-proof door body 201 and the explosion-proof cabinet body 101 are closed, the inner energy absorption plate 204 will be just placed between the explosion-proof door body 201 and the inner protection box 401; When the electrical equipment inside the entire device starts to operate, the cooling device 5 and the ventilation device 6 respectively arranged on the upper and lower sides of the inner cabinet device 4 will operate synchronously, wherein the cooler 501 fixed to the top of the explosion-proof cabinet 101 by the shock-absorbing frame 502 and the suspension pile 503 will use the air inlet pipe 504 to transport the external air to the inside of the cooler 501, and the cooler 501 will quickly cool the air transported from the outside, and quickly blow the cold air into the interior of the entire explosion-proof cabinet 101 through the centrifugal fan 505, so as to dissipate heat and cool down the electrical equipment, and at the same time, the dehumidifier 603 and the filter fan 60 2 can effectively filter the water vapor in the air inside the entire outer cabinet device 1 and store it inside the filter box 601, so as to avoid condensation inside the outer cabinet device 1 due to the temperature drop caused by the operation of the cooling device 5, and maintain appropriate internal humidity. At the same time, the operation of the filter fan 602 will exchange air between the inside and outside of the entire outer cabinet device 1. When the cooling device 5 and the ventilation device 6 are in operation, with the assistance of the ventilation network pipe 104 and the air intake network pipe 103, it will prevent external dust and foreign matter from entering the interior of the outer cabinet device 1 to the greatest extent, thereby affecting the internal equipment; If a short circuit occurs due to internal or external factors and the circuit breaker cannot function effectively, so that an open flame may occur or has occurred, the flame retardant device 3 will start to operate. By using the induction valve tube 304 and the internal voltage sensor and other structures, after detecting the voltage abnormality, the control valve will be started, and the inert gas pre-stored in the inert gas storage tank 302 will be filled into the interior of the entire outer cabinet device 1 at the fastest speed through the nozzle 305 through the connecting pipe 303, so as to effectively curb the possible danger.
