Description

Technical Field

[0001] This invention relates to the field of electrical control cabinet technology, specifically a CCB control cabinet that is explosion-proof, fire-proof, and safe to operate. Background Technology

[0002] CCB control cabinets are a type of electrical control equipment designed for specific industrial scenarios, commonly found in chemical supply (such as CDU and CMDU) and cold chain logistics (such as cryogenic tank trucks). In chemical supply systems, the CCB is mainly responsible for the filling and storage management of chemicals in tank trucks, while cryogenic tank truck control cabinets focus on the control of environmental parameters such as temperature and humidity during refrigerated transportation. Both have core functions such as intelligent control, safety protection, and status monitoring.

[0003] With the rapid improvement of industrial automation and the increasingly stringent safety requirements of industries such as hazardous chemicals, energy, and manufacturing, CCB (Compact Control Cabinet) control cabinets are widely used in various industries. Explosion-proof control cabinets use welded steel plates or die-cast aluminum alloy shells with high-voltage electrostatic powder coating on the surface. Some models adopt a composite structure of explosion-proof and increased safety types, which isolates internal faults through sealing.

[0004] The wiring generated during installation inside the cabinet is complex, which increases the difficulty of finding and rewiring the wiring during maintenance and rewiring, thus affecting production efficiency.

[0005] When the electrical control system inside the cabinet is running, problems such as single point of failure, electromagnetic interference (EMC), and gas leakage are particularly prominent. During the gas leakage and alarm handling process, the gas continues to spread inside the control cabinet, causing a significant increase in concentration. In a flammable and explosive environment, this can easily lead to safety hazards. Existing cabinets tend to directly shut down the leaking component when dealing with such problems. However, stopping the component does not guarantee that the leakage will stop. At the same time, existing cabinets cannot promptly handle the gas that has already leaked inside the cabinet, posing a great safety hazard. Summary of the Invention

[0006] In order to solve the above problems, the present invention provides a CCB control cabinet that is explosion-proof, fire-proof and safe to operate.

[0007] The present invention adopts the following technical solution: a CCB control cabinet for explosion-proof, fire-proof and safe operation, including a cabinet, a bottom compartment located at the lower end of the cabinet, and a winding mechanism housed in the bottom compartment;

[0014] The door and the bottom compartment are connected by hinges and form a rotating structure.

[0015] In some embodiments, the explosion-proof ventilation mechanism includes a ventilation shaft fixedly installed at the central shaft of the second drive gear, and ventilation fans are evenly distributed on the ventilation shaft;

[0016] The drive wheel is fixedly mounted on the end of the exhaust shaft.

[0017] In some embodiments, an exhaust fan is fitted with an exhaust duct fixed to the inner wall of the bottom compartment, and a collection net is provided at the front end of the exhaust duct;

[0018] The cabinet unit is equipped with a mounting base at the end close to the exhaust shaft. A filter chamber is threadedly connected to the mounting base, and filter screens are distributed inside the filter chamber.

[0019] In some embodiments, the second drive gear is connected to the first drive gear via a stabilizer, and the first drive gear meshes with the second drive gear.

[0020] A third drive gear is provided on the side of the first drive gear. The third drive gear meshes with the first drive gear and is connected to the winding transmission mechanism.

[0021] In some embodiments, the winding drive mechanism includes a first mounting bracket fixedly disposed on the cross frame, and a drive rod is provided through the lower end of the first mounting bracket;

[0022] The drive rod is provided with sleeve rods and guide gears at intervals, and the guide gears are meshed with the third drive gear.

[0023] A transmission gear is installed on the side end of the drive rod.

[0024] In some embodiments, a stabilizer bar is also installed on the side end of the drive rod, and a mating bearing is provided between the stabilizer bar and the transmission gear;

[0025] The stabilizer bar has limiting rails distributed on it and is slidably mounted through the bottom compartment, with a hand handle installed at its end.

[0026] In some embodiments, the cable winding mechanism includes a second mounting bracket fixedly mounted on the crossbeam, and a mounting rod is connected to the second mounting bracket;

[0027] The mounting rod has equidistant adapter gears that mesh with the transmission gears.

[0028] In some embodiments, the winding mechanism includes a stabilizing main frame fixed to the inner wall of the bottom compartment, and a stabilizing support is connected to the stabilizing main frame;

[0029] The other end of the stabilizing bracket is connected to the inside of the winding drum via a limiting bearing. The inner wall of the winding drum is provided with guide toothed rings, which mesh with the adapter gear.

[0030] In some embodiments, a side baffle is installed on the outer wall of the winding drum, and mounting screw holes are evenly provided on the side baffle. A locking mechanism for fixing the line is provided on the mounting screw holes.

[0031] The locking mechanism includes a C-shaped buckle, a side block is installed on the side of the C-shaped buckle, and an internally threaded sleeve is provided through the side block;

[0032] The internally threaded sleeve is internally threaded and connected to a mounting screw, which is threadedly connected to the mounting screw hole.

[0033] An extension rod is connected to the mounting screw, and a cross-shaped screw head is installed at the end of the extension rod.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] This invention uses a drive mechanism to simultaneously drive the explosion-proof ventilation mechanism and the cable winding mechanism, which can quickly replace the air inside the cabinet, cool the temperature inside the cabinet, and dilute leaked gas inside the cabinet to prevent gas from accumulating inside the cabinet and causing safety threats. At the same time, it works in conjunction with the cable winding guide mechanism to drive the cable winding mechanism, which winds up excess cable one by one to prevent cable accumulation.

[0036] This invention uses a transmission belt to drive the exhaust shaft, which is equipped with a transmission wheel, to rotate. The exhaust shaft causes air to circulate inside the cabinet. The flowing air guides the airflow into the collection mesh cylinder and then into the exhaust duct for discharge. The filter screen installed in the filter chamber at the end of the exhaust duct performs preliminary purification of the discharged airflow. After purification, the discharged gas has a lower concentration of leaked gas, thus improving the safety of equipment operation.

[0037] This invention achieves intermittent driving of the drive rod by evenly distributing the guide gear and the sleeve rod at equal intervals on the drive rod. During the intermittent driving of the drive rod, the transmission gear is also driven intermittently. During the driving of the transmission gear, the corresponding adapter gear will mesh with it one by one, thereby achieving the sequential driving and operation of the adapter gear.

[0038] This invention uses the rotational meshing of the adapter gear with the corresponding guide gear ring to drive the winding drum, which is equipped with the corresponding guide gear ring, to rotate at the limit bearing. Before the winding drum rotates, the wire is initially fixed on the winding drum. When the winding drum is winding up, the excess wire can be quickly collected, avoiding the accumulation of wire in the bottom compartment and causing entanglement. This improves the efficiency and convenience of equipment maintenance and replacement.

[0039] In summary, this invention, through ingenious mechanical linkage design, organically integrates exhaust heat dissipation / gas treatment functions with circuit management functions, achieving proactive environmental safety control and refined circuit layout management. It not only significantly improves the intrinsic safety level of the CCB control cabinet in harsh industrial environments but also effectively reduces the total life-cycle operating costs by improving maintainability, demonstrating extremely high practical value and promising prospects for widespread application.

[0061] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] A CCB control cabinet for explosion-proof, fire-proof, and safe operation includes a cabinet unit 1, a lower compartment 1002 of the cabinet unit 1, and a cable winding mechanism 6 (e.g., ...) within the lower compartment 1002. Figures 1 to 3 As shown), a crossbeam 1006 is installed through the middle of the top of the bottom compartment 1002, and a drive mechanism 2 (as shown) is installed on the crossbeam 1006. Figures 4 to 6 (As shown).

[0063] Specifically, cabinet 1 is equipped with cabinet door 1001. Cabinet 1 and cabinet door 1001 are made of welded steel plate or die-cast aluminum alloy shell, and the surface is treated with high-pressure electrostatic powder coating. The combination of welded steel plate, die-cast aluminum alloy shell, and high-pressure electrostatic powder coating can reliably achieve the explosion-proof and fire-resistant protection strength of cabinet 1. Both sides of the bottom compartment 1002 are equipped with compartment doors 1003. The compartment doors 1003 are equipped with lock cylinders 1004 that lock with the bottom compartment 1002. Hinges 1005 are installed at the connection between the compartment doors 1003 and the bottom compartment 1002. The compartment doors 1003 and the bottom compartment 1002 form a rotating structure through the hinges 1005. The lock cylinders 1004 are opened during maintenance and locked when not in use to ensure the safe operation of the equipment inside cabinet 1 (e.g., ...). Figures 1 to 3 (As shown).

[0064] Specifically, the drive mechanism 2 includes a drive motor 2001 fixedly mounted on the crossbeam 1006 via a frame and a transmission belt 2002 mounted at the output end of the drive motor 2001. The transmission belt 2002 drives the transmission wheel 2003 (e.g., Figure 7 (As shown).

[0065] A second drive gear 2006 is mounted on one side of the transmission wheel 2003. The second drive gear 2006 is mounted on the stabilizer 2004. A first drive gear 2005 is mounted on the stabilizer 2004, and the first drive gear 2005 meshes with the second drive gear 2006. A third drive gear 2007 is mounted on the side of the first drive gear 2005, and the third drive gear 2007 meshes with the first drive gear 2005. The stabilizer 2004 stabilizes the first drive gear 2005, the second drive gear 2006, and the third drive gear 2007, ensuring their rotational drive. The operating force of the drive motor 2001 is transmitted to various structural parts through the first drive gear 2005, the second drive gear 2006, and the third drive gear 2007, realizing the overall operation of the equipment (e.g., ...). Figure 7 (As shown).

[0066] The transmission wheel 2003 simultaneously drives the explosion-proof ventilation mechanism 3. The explosion-proof ventilation mechanism 3 includes an exhaust shaft 3003 fixedly connected to the central shaft of the second drive gear 2006. The transmission wheel 2003 is located at the end of the exhaust shaft 3003. The transmission wheel 2003 forms a transmission drive structure through the transmission belt 2002. The rotation of the transmission wheel 2003 drives the exhaust shaft 3003 to rotate. Exhaust fans 3004 are evenly distributed on the exhaust shaft 3003. The transmission belt 2002 drives the exhaust shaft 3003, which is equipped with the transmission wheel 2003, to rotate. The exhaust fans 3004 promote air circulation inside the cabinet unit 1 (e.g., air circulation). Figures 6 to 8 (As shown).

[0067] An exhaust fan 3004 is located inside an exhaust duct 3001, which is fixedly installed on the inner wall of the bottom chamber 1002. A collection screen 3002 is installed at the front end of the exhaust duct 3001, with evenly spaced through holes. A stabilizing support 3005 is mounted on the exhaust shaft 3003 near the mounting base 1007 via bearings. The stabilizing support 3005 forms a rotating structure with the inner wall of the mounting base 1007 via bearings, thus providing stable drive for the exhaust shaft 3003 (e.g., ...). Figure 3 and Figure 8 (As shown).

[0068] A mounting base 1007 is installed at the end of the cabinet unit 1 near the exhaust shaft 3003. The surface of the mounting base 1007 is provided with a threaded structure (such as...). Figure 3As shown), a filter chamber 3006 is provided on the mounting base 1007, and filter screens 3007 are distributed on the filter chamber 3006. The filter chamber 3006 and the mounting base 1007 are connected by a threaded connection. When the exhaust shaft 3003 is driven, the flowing air is guided into the collection screen cylinder 3002. The filter screens 3007 in the filter chamber 3006 on the mounting base 1007 perform preliminary purification of the exhaust airflow, reduce the concentration of leaked gas, dilute the leaked gas in the cabinet, and prevent the gas from accumulating in the cabinet and causing a safety threat. At the same time, it can quickly replace the air in the cabinet and cool down the temperature inside the cabinet (e.g., Figure 3 and Figure 8 (As shown).

[0069] The second drive gear 2006 drives the winding transmission mechanism 4 and the winding guide mechanism 5. A winding mechanism 6 (such as...) is provided outside the winding transmission mechanism 4 and the winding guide mechanism 5. Figures 5 to 6 (As shown).

[0070] The winding drive mechanism 4 includes a first mounting bracket 4001 fixedly mounted on the crossbeam 1006. A drive rod 4002 is passed through the lower part of the first mounting bracket 4001. Sleeve rods 4003 and guide gears 4004 are spaced apart on the drive rod 4002. The drive rod 4002 is slidably connected to the first mounting bracket 4001. The guide gears 4004 are evenly distributed at equal intervals on the drive rod 4002 and are meshed with a third drive gear 2007. The evenly distributed guide gears 4004 and sleeve rods 4003 on the drive rod 4002 enable intermittent driving of the drive rod 4002. During intermittent driving of the drive rod 4002, the driving state of the transmission gear 4005 is within a controllable range. When controlling the driving of the transmission gear 4005, the corresponding winding guide mechanism 5 is driven (e.g., ...). Figure 6 and Figure 9 (As shown).

[0071] The end of the drive rod 4002 is connected to the stabilizer rod 4006. A transmission gear 4005 is provided at the connection point, and a mating bearing 4009 is installed between the connection point and the transmission gear 4005. The stabilizer rod 4006 and the drive rod 4002 form a rotating structure through the mating bearing 4009. The mating bearing 4009 installed between the stabilizer rod 4006 and the drive rod 4002 allows for adjustment of the driving state between them. Limiting cams 4007 are distributed on the stabilizer rod 4006. The stabilizer rod 4006 and the limiting cams 4007... All 007 components are slidably mounted on the bottom compartment 1002. The wall panel of the bottom compartment 1002 has a guide groove or guide hole that precisely matches the cross-sectional shape and size of the limiting cam 4007. The limiting cam 4007 limits the stabilizing rod 4006, preventing it from rotating and maintaining a stable state. This ensures that operators are not injured during direct operation. A handle 4008 is installed at the end of the stabilizing rod 4006. By gripping the handle 4008, the position of the stabilizing rod 4006 can be adjusted, enabling zoned driving of multiple winding mechanisms 6 (e.g., ...). Figure 4 and Figure 9 (As shown).

[0072] The winding mechanism 6 includes a stabilizing main frame 6004 fixed to the inner wall of the bottom hopper 1002. A stabilizing bracket 6003 is connected to the stabilizing main frame 6004. A limit bearing 6002 is installed between the winding drum 6001 and the stabilizing bracket 6003. The winding drum 6001 is mounted on the limit bearing 6002. The winding drum 6001 and the stabilizing bracket 6003 form a rotating structure (e.g., ...) through the limit bearing 6002. Figure 10 and Figure 11 (As shown).

[0073] A side baffle 6006 is installed at one end of the cable reel 6001. The side baffle 6006 is integrated with the cable reel 6001 and forms a "U" groove structure. The "U" groove structure can quickly collect excess cable during winding, avoiding cable accumulation at the bottom compartment 1002 and tangling (e.g., Figure 12 (As shown).

[0074] The cable winding guide mechanism 5 includes a second mounting bracket 5001 fixedly mounted on the crossbeam 1006. A mounting rod 5002 is connected to the second mounting bracket 5001. Adapter gears 5003 are evenly distributed at equal intervals on the mounting rod 5002. The adapter gears 5003 and the mounting rod 5002 are rotatably connected. The adapter gears 5003 and the transmission gear 4005 are meshed. The adapter gears 5003 serve as a driving adapter structure. When the adapter gears 5003 are meshed and driven by the transmission gear 4005, they can rotate. When the adapter gears 5003 rotate, the corresponding guide ring 6005 can be driven, thus driving the cable winding drum 6001 (e.g., ...). Figure 9 and Figure 11(As shown).

[0075] The inner wall of the cable reel 6001 is provided with guide toothed rings 6005, which are meshed with the adapter gear 5003. The rotation of the adapter gear 5003 meshes with the corresponding guide toothed ring 6005, causing the cable reel 6001, which has the corresponding guide toothed ring 6005 installed, to rotate at the limit bearing 6002. Before the cable reel 6001 rotates, the cable is initially fixed on the cable reel 6001. When the cable reel 6001 rewinds, the excess cable can be collected (e.g., ...). Figures 11 to 12 (As shown).

[0076] The side baffle 6006 has evenly spaced mounting screw holes 6007. A wire locking mechanism 602 is installed in each mounting screw hole 6007. The wire locking mechanism 602 includes a C-shaped buckle 6021. A side block 6022 is located on the side of the C-shaped buckle 6021. An internally threaded sleeve 6023 is threaded through the side block 6022. A mounting screw 6024 is installed inside the internally threaded sleeve 6023. The mounting screw 6024 and the internally threaded sleeve 6023 are threadedly connected. The mounting screw 6024 and the mounting screw hole 6007 are also threadedly connected. This threaded connection between the mounting screw 6024 and the internally threaded sleeve 6023 ensures that the wiring is not excessively compressed during installation, providing adequate protection for the wiring (e.g., ...). Figure 13 and Figure 14 (As shown).

[0077] An extension rod 6025 is connected to the mounting screw 6024. A screw head 6026 is installed at the end of the extension rod 6025. The screw head 6026 is designed with a cross-shaped structure, which makes it easier to operate with fingers (e.g., ...). Figure 14 (As shown).

[0078] Working principle: Electronic components are installed inside cabinet 1. The drooping wires generated after installation need to be stored for easy adjustment and use later. In addition, if flammable or explosive gas leaks occur inside cabinet 1, they need to be dealt with in time. When the electronic components inside cabinet 1 are running, a large temperature difference will be generated. When cabinet 1 is in use, the high temperature inside needs to be dissipated.

[0079] When the equipment is in operation, the drive mechanism 2 runs, the drive motor 2001 drives the transmission wheel 2003 on the transmission belt 2002 to rotate, and the second drive gear 2006 runs at the same time. The second drive gear 2006 meshes with the first drive gear 2005 to transmit power and drive the third drive gear 2007.

[0080] The lock cylinder 1004 is opened with the corresponding key, and then the door 1003 is rotated through the hinge 1005 to open it at the bottom compartment 1002, which facilitates subsequent equipment operation or maintenance.

[0081] Based on the above, the following classifications will be introduced:

[0082] When hanging wires need to be stored:

[0083] When storing the hanging cable, the cable first needs to be organized. The cable in the corresponding vertical direction is stored on the winding mechanism 6 in the corresponding vertical direction. When storing, the extended cable is folded, and the cable is folded in half at the midpoint of the hanging section. The cable is then fastened between the side baffle 6006 and the winding drum 6001 in the "U" groove. The mounting screw holes 6007 evenly opened on the side baffle 6006 can flexibly position the cable.

[0084] During positioning, take out the pre-prepared locking mechanism 602, insert the mounting screw 6024 into the mounting screw hole 6007, and turn the cross-shaped screw head 6026 to rotate the extension rod 6025. The mounting screw 6024 installed on the extension rod 6025 will also enter the mounting screw hole 6007. During installation, fasten the C-type buckle 6021 onto the section of the line. During tightening, the internal thread sleeve 6023 is also in a threaded running state with the mounting screw 6024. Under the limit of the line, the position of the C-type buckle 6021 remains unchanged. After the mounting screw 6024 is installed, the extension rod 6025 will push against the side block 6022, pushing the C-type buckle 6021 towards the fixed point of the line, completing the limit of the middle section of the line.

[0085] During winding, the operator adjusts the length of the corresponding drive stabilizer bar 4006 according to the position of the winding drum 6001. While operating, the operator holds the handle 4008 and pulls the stabilizer bar 4006. The upper limit rail 4007 of the stabilizer bar 4006 passes through the bottom compartment 1002, preventing the stabilizer bar 4006 from rotating initially. Simultaneously, the position of the transmission gear 4005 changes, engaging with the corresponding adapter gear 5003. When the adapter gear 5003 rotates, the corresponding guide gear ring 6005 is driven. The drive of the guide gear ring 6005 drives the winding drum 6001 for rapid winding. After winding is complete, the stabilizer bar 4006 is pushed again, causing the guide gear 4004 to disengage from the third drive gear 2007, stopping the drive of the drive bar 4002.

[0086] When handling flammable and explosive gas leaks:

[0087] Beforehand, screw the filter chamber 3006 onto the mounting base 1007 and check the filter screen plates 3007 distributed inside the filter chamber 3006;

[0088] When the exhaust shaft 3003 is running, the exhaust fan 3004 installed on the exhaust shaft 3003 creates a wind pressure zone. The collection screen 3002 collects the flammable and explosive gas leaked from the cabinet 1 and discharges it through the exhaust duct 3001 to the filter chamber 3006. After preliminary filtration by the filter screen 3007 in the filter chamber 3006, the gas is discharged, preventing the gas concentration in the cabinet 1 from gradually increasing while waiting for treatment. This makes the device safer and more efficient during operation, diluting the leaked gas in the cabinet and preventing the gas from accumulating in the cabinet and causing a safety threat.

[0089] When components operate at high temperatures and need to dissipate heat:

[0090] When the exhaust shaft 3003 is running, the exhaust fan 3004 installed on the exhaust shaft 3003 generates wind pressure, which discharges the high-temperature gas in the cabinet 1, and the low-temperature gas quickly enters the cabinet 1 through the ventilation screen, so as to quickly exchange and cool down the temperature inside the cabinet 1.

[0091] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
