Description

Technical Field

[0001] This utility model relates to the field of explosion-proof safety technology for distribution boxes, specifically an explosion-proof safety distribution box. Background Technology

[0002] The explosion-proof function of distribution boxes is crucial. In hazardous environments such as flammable and explosive environments, ordinary distribution boxes may cause explosion accidents due to electric sparks, high temperatures, etc. Explosion-proof distribution boxes use special structures and materials to effectively isolate electric sparks and arcs generated by internal electrical components, prevent them from coming into contact with external explosive gases and dust, avoid explosions, and ensure the safety of personnel, normal operation of equipment, and stability of the production environment.

[0003] However, in the event of an explosion, the traditional distribution box, due to its strong sealing, may suffer localized explosion damage when subjected to high-voltage impact, causing serious injury to people in the vicinity. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an explosion-proof safety distribution box that can quickly conduct pressure treatment on the internal high voltage when the distribution box explodes, thereby uniformly dispersing the high-pressure gas inside, and thus better avoiding the distribution box from breaking due to high-pressure impact, and preventing fragments from flying onto surrounding operators and mechanical equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof safety distribution box, comprising a distribution box cabinet and a distribution box door. The distribution box door is rotatably mounted on one side of the distribution box cabinet via a pivot. Support blocks are fixed at the four corners of the interior of the distribution box cabinet, and the cross-section of the support blocks is triangular. The surfaces of the support blocks are evenly spaced with slots. The top of the distribution box cabinet has several sets of hole-like structures, and connecting blocks are inserted into the interior of each set of hole-like structures. Sealing rings are fitted on the outer sides of each set of connecting blocks. The tops of the connecting blocks are fixed to the distribution box cabinet with bolts. Pre-breaking plates are fixed inside the connecting blocks, and grooves are engraved at both ends of the pre-breaking plates.

[0006] By adopting the above technical solution, the triangular support blocks fixed at the four corners inside the distribution box cabinet not only reinforce the inside of the distribution box cabinet and improve its structural strength, but also provide a fixing function for the electronic components and circuits installed inside by the equally spaced slots on the surface of the support blocks, preventing wire tangling and reducing safety hazards. Several sets of hole-like structures on the top of the distribution box cabinet are used for plugging in the connecting blocks. The sealing rings sleeved on the outside of the connecting blocks can seal the connection between the connecting blocks and the distribution box cabinet, preventing the entry of external dangerous gases. In the event of an explosion inside the distribution box cabinet, the pre-breakable plate fixed inside the connecting blocks will break under high pressure impact due to its thin thickness and the grooves opened at both ends, releasing the internal high-pressure gas and preventing the distribution box cabinet from breaking.

[0007] Furthermore, the distribution box cabinet is fastened to one end of the distribution box door by fastening screws.

[0008] By adopting the above technical solution, the distribution box door and the distribution box cabinet are fastened together by fastening screws. The function of the fastening screws is to ensure that the distribution box door and the distribution box cabinet fit tightly together to form an effective seal, preventing external dangerous gases or impurities from entering the distribution box, thereby ensuring the safe operation of the distribution box in flammable, explosive and other dangerous environments.

[0009] Furthermore, the bottom of the distribution box cabinet is fixed with distribution box support legs, one side of the distribution box door is provided with a linkage lock, and the other side of the distribution box door is provided with several sets of control switches.

[0010] By adopting the above technical solution, the distribution box support legs fixed at the bottom of the distribution box cabinet provide stable support for the distribution box cabinet. The linkage lock on one side of the distribution box door is used to lock the distribution box door and the distribution box cabinet. The several sets of control switches on the other side of the distribution box door are used to control the on / off of the electrical components inside the distribution box.

[0011] Furthermore, the contact surfaces of the distribution box cabinet and the distribution box door are both covered with sealing strips, and the two sets of sealing strips are fitted together.

[0012] By adopting the above technical solution, the sealing strips affixed to the contact surfaces of the distribution box cabinet and the distribution box door are used to fill the tiny gaps between the cabinet and the distribution box door. The two sets of sealing strips are fitted together, which further enhances the sealing effect and ensures the stability and reliability of the distribution box in harsh environments.

[0013] Furthermore, the inner back of the distribution box cabinet is provided with two sets of mounting brackets, and the interior of both sets of mounting brackets is provided with sliding grooves.

[0014] By adopting the above technical solution, the sliding grooves inside each mounting bracket allow the mounting plate to be stably adjusted within it, thereby adapting to different installation needs and spatial layouts, and improving the adaptability and practicality of the distribution box.

[0015] Furthermore, one end of each of the two sets of mounting brackets is provided with several sets of first mounting holes, and the other end of each of the two sets of mounting brackets is provided with four sets of slots.

[0016] By adopting the above technical solution, the several sets of first mounting holes opened at one end of the two sets of mounting brackets can cooperate with the second mounting holes on the insert, thereby locking them with nuts. The four sets of slots opened at the other end of the two sets of mounting brackets allow the inserts at the four corners of the mounting plate to be inserted into the mounting bracket.

[0017] Furthermore, the interior of the slide groove is provided with several sets of mounting plates, and each set of mounting plates has a insert fixed at one of its four corners, which are respectively adapted to and engaged with four sets of slots.

[0018] By adopting the above technical solution, the main function of the several sets of mounting plates that slide inside the chute is to provide a flexible mounting platform for electrical components or equipment inside the distribution box. By sliding inside the chute, the mounting plates can be adjusted in position according to actual installation needs and spatial layout, thereby optimizing the arrangement of components inside the distribution box and improving space utilization. The inserts fixed at the four corners of the several sets of mounting plates are adapted and engaged with the four sets of slots respectively. This design not only enhances the stability of the mounting plates, but also provides a convenient way to install and disassemble them.

[0019] Furthermore, each of the four sets of inserts has a second mounting hole in the middle, and the inserts are respectively arranged in a one-to-one correspondence with the slots.

[0020] By adopting the above technical solution, the second mounting hole opened in the middle of the four sets of inserts is mainly used to connect and fix the mounting plate to the first mounting hole on the mounting bracket, so as to ensure its stability and safety. The four sets of inserts are respectively set in correspondence with the slots. This design ensures that the mounting plate can be accurately positioned and fixed on the mounting bracket.

[0021] In summary, the present invention has the following main advantages:

[0022] 1. This utility model, by setting a connecting block, a pre-breaking plate, and engraved grooves, places a sealing ring on the outside of the connecting block, then inserts the connecting block and its outer sealing ring into the top of the distribution box cabinet and fixes it with fastening bolts. This allows the sealing ring to provide a sealing function at the connection between the connecting block and the distribution box cabinet. When an explosion occurs inside the distribution box cabinet, the high-pressure gas inside will impact the entire interior of the distribution box cabinet. Because the pre-breaking plate inside the connecting block is relatively thin, and engraved grooves are engraved at both the top and bottom ends of the pre-breaking plate, the pre-breaking plate will break upwards when subjected to high-pressure impact, thereby releasing the high-pressure gas inside the distribution box cabinet and preventing the distribution box cabinet from breaking.

[0023] 2. This utility model uses support blocks and slots to fix support blocks at the four corners of the inside of the distribution box cabinet, so that the support blocks can provide reinforcement to the inside of the distribution box cabinet. At the same time, several sets of slots are evenly spaced on the surface of the support blocks, thereby providing a wiring fixation function for electronic components installed on the mounting plate, thus preventing the wires inside the distribution box cabinet from being too messy and causing unnecessary safety hazards.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] In this embodiment:

[0033] An explosion-proof safety distribution box, such as Figures 1-6 As shown, the distribution box includes a cabinet 1 and a door 3. The door 3 is rotatably mounted on one side of the cabinet 1 via a pivot. Support blocks 8 are fixed at the four corners of the cabinet 1. The cross-section of the support blocks 8 is triangular. The surface of the support blocks 8 is provided with slots 9 at equal intervals. The top of the cabinet 1 has several sets of hole-like structures. Connecting blocks 17 are inserted into the inside of the hole-like structures. Sealing rings 18 are fitted on the outside of the connecting blocks 17. The tops of the connecting blocks 17 are fixed to the cabinet 1 by bolts. Pre-breaking plates 19 are fixed inside the connecting blocks 17. The two ends of the pre-breaking plates 19 are provided with engraved grooves 20.

[0034] The distribution box cabinet 1 has triangular support blocks 8 at its four corners, which can not only strengthen the cabinet structure and enhance its strength, but also fix the internal electronic components and circuits with equally spaced slots 9 on its surface, avoiding messy wires and eliminating safety hazards. In addition, the hole-like structure on the top of the cabinet is used to insert the connecting block 17. The sealing ring 18 on the outside of the connecting block 17 can seal the connection and isolate the external dangerous gas. If an explosion occurs inside the cabinet, the thin pre-breaking plate 19 with engraved grooves 20 inside the connecting block 17 will break, releasing high-pressure gas and preventing damage to the cabinet.

[0035] See Figure 1 and Figure 2 The distribution box cabinet 1 and the distribution box door 3 are fastened together by fastening screws 4;

[0036] The distribution box door 3 and the distribution box cabinet 1 are firmly connected by fastening screws 4. The fastening screws 4 can ensure that the door and the cabinet fit tightly and achieve a good seal, effectively preventing external dangerous gases or impurities from entering the distribution box, thereby ensuring the safe and stable operation of the distribution box in a dangerous environment.

[0037] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The bottom of the distribution box cabinet 1 is fixed with distribution box support legs 2, and a linkage lock 5 is provided on one side of the surface of the distribution box door 3, and several sets of control switches 6 are provided on the other side of the surface of the distribution box door 3.

[0038] The distribution box cabinet 1 is equipped with distribution box support legs 2 at the bottom, which can stably support the cabinet and ensure its stable placement, preventing it from shaking or tipping over. One side of the distribution box door 3 is equipped with a linkage lock 5, which can lock the door 3 and the cabinet 1 to prevent unauthorized personnel from opening it. The other side is equipped with multiple sets of control switches 6, which can flexibly control the on / off status of the electrical components inside the box, taking into account both safety protection and convenient operation.

[0039] See Figure 3 and Figure 4 Both the cabinet body 1 and the door 3 of the distribution box are fitted with sealing strips 7, and the two sets of sealing strips 7 are fitted together.

[0040] Among them, the contact surfaces of the distribution box cabinet 1 and the distribution box door 3 are both covered with sealing strips 7. These strips can fill the gaps between the two, and the sealing performance is better after the two sets of strips are attached, which effectively ensures the stable and reliable operation of the distribution box in harsh environments.

[0041] See Figure 3 and Figure 4 The back of the distribution box cabinet 1 is provided with two sets of mounting brackets 10, and the interior of both sets of mounting brackets 10 is provided with sliding grooves 11.

[0042] Each mounting bracket 10 has a sliding groove 11, which allows the mounting plate 14 to slide smoothly and adjust its position, thereby meeting different installation requirements and spatial layouts and improving the applicability and practicality of the distribution box.

[0043] See Figure 3 and Figure 4 One end of each of the two sets of mounting brackets 10 is provided with several sets of first mounting holes 12, and the other end of each of the two sets of mounting brackets 10 is provided with four sets of slots 13.

[0044] Among them, one end of each of the two sets of mounting brackets 10 is provided with multiple first mounting holes 12, which can be aligned with the second mounting holes 16 on the insert 15 and then locked with nuts. The other end of the brackets 10 has four sets of slots 13, which can be used to insert the inserts 15 at the four corners of the mounting plate 14.

[0045] See Figure 3 , Figure 4 and Figure 6 The slide groove 11 has several sets of mounting plates 14 slidably arranged inside, and each set of mounting plates 14 has a insert 15 fixed at its four corners, which are respectively adapted to and engaged with four sets of slots 13.

[0046] Multiple mounting plates 14 can be slidably installed in the slide groove 11 to provide a flexible and adjustable installation platform for electrical components or equipment in the distribution box. This facilitates adjusting the position according to actual needs and spatial layout, optimizing component arrangement, and improving space utilization. The inserts 15 fixed at the four corners of the mounting plate 14 are adapted to engage with the slots 13, which not only enhances the stability of the mounting plate but also facilitates installation and disassembly.

[0047] See Figure 3 , Figure 4 and Figure 6 Each of the four sets of inserts 15 has a second mounting hole 16 in the middle, and the inserts 15 are respectively arranged in a one-to-one correspondence with the slots 13.

[0048] The four sets of inserts 15 have a second mounting hole 16 in the middle, which is used to cooperate with the first mounting hole 12 on the mounting bracket 10 to achieve connection and fixation, so as to ensure the stability and safety of the mounting plate 14. Moreover, the four sets of inserts 15 and slots 13 correspond one by one, which can ensure that the mounting plate 14 is accurately positioned and firmly installed on the mounting bracket 10.

[0049] The implementation principle of this embodiment is as follows: First, the distribution box cabinet 1 is stably placed in the designated position using the distribution box support legs 2. Then, the locking mechanism 5 on the distribution box door 3 is turned to release the lock between the distribution box cabinet 1 and the distribution box cabinet 1. At the same time, the fastening screws 4 are removed from one side of the distribution box cabinet 1 and the distribution box door 3 using an electric screwdriver, allowing the distribution box door 3 to open and close with the distribution box cabinet 1 via a pivot. Then, the electronic components to be installed are fixed on several sets of mounting plates 14, and the inserts 15 at the four corners of the mounting plates 14 are engaged with the sliding grooves 11 inside the mounting bracket 10 through the slots 13 on one side of the mounting bracket 10. The mounting plates 14 slide inside the sliding grooves 11, so that the second mounting holes 16 on the inserts 15 engage with the first mounting holes 16 on the mounting bracket 10. Align the mounting holes 12 and connect them with fastening bolts. Then, place the circuits of the electronic components fixed on the mounting plate 14 into the slots 9 evenly spaced on the surface of the support block 8 to organize and bundle the circuits. Then, connect the switch controllers of the electronic components installed on the mounting plate 14 to several sets of control switches 6 on the distribution box door 3. Finally, close the distribution box door 3 to the distribution box cabinet 1 through the pivot and make the sealing strips 7 on the distribution box cabinet 1 and the distribution box door 3 stick together to seal the inside of the distribution box cabinet 1. Then, use an electric screwdriver to tighten the fastening screws 4 to secure the distribution box cabinet 1 and the distribution box door 3, and lock the distribution box cabinet 1 and the distribution box door 3 with the linkage lock 5.

[0050] The component sealing ring 18 is fitted onto the outside of the component connecting block 17. Then, the component connecting block 17 with the outer sealing ring 18 is inserted into the top of the component distribution box cabinet 1 and fixed with fastening bolts. This achieves the sealing effect of the sealing ring 18 at the connection between the connecting block 17 and the distribution box cabinet 1. When an explosion occurs inside the component distribution box cabinet 1, the high-pressure gas inside will fill the entire internal space of the distribution box cabinet 1. Since the pre-fracture plate 19 inside the component connecting block 17 is relatively thin and has engraved grooves 20 at both its upper and lower ends, the pre-fracture plate 19 will break upward when subjected to high pressure impact, thereby releasing the high-pressure gas inside the distribution box cabinet 1 and preventing the distribution box cabinet 1 from breaking.
