Description

Technical Field

[0001] The invention belongs to the technical field of electric control cabinets, and in particular relates to an explosion-proof and flame-retardant electric control cabinet that can be efficiently clustered. Background Art

[0002] The control cabinet is a closed or semi-closed metal cabinet or screen that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment according to the requirements of electrical wiring. Its layout should meet the requirements of normal operation of the power system, facilitate maintenance, and not endanger the safety of personnel and surrounding equipment. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. In case of faults or abnormal operation, the circuit is cut off or an alarm is issued with the help of protective electrical appliances. For the messy wires in the electrical control cabinet, it is usually necessary to bundle them to make the wires neat and avoid entanglement.

[0003] In the prior art, electrical control cabinets usually use wire clamps to organize and limit wires during use. Different groups of wires are classified and limited in the limit clamps, so that different wires have a suitable bundling effect to avoid entanglement. However, the lengths of wires in actual electrical cabinets are different. For the current wire clamps, usually only different wires can be limited and clamped in the limit clamps. Some wires with longer lengths cannot be effectively bundled, resulting in local dragging. Moreover, for wires of different lengths, the actual adaptability of the bundling effect is general. The effect of bundling the wires in the electrical control cabinet is poor, and there is local dragging and confusion, and the actual use effect is not good.

[0004] In addition, the electrical control cabinets in the prior art, when actually used, have complex internal electrical arrangements and, when an electrical fault occurs, may result in dangerous situations such as explosions. The current electrical control cabinets are monitored by adding temperature and flame sensors, and sound an alarm when a fault occurs, reminding patrol personnel to extinguish the fire and carry out maintenance. It actually takes time for the alarm to be discovered by patrol personnel, and it still takes time to react to perform fire extinguishing operations. It is impossible to quickly eliminate the fire in the event of a sudden combustion of the electrical control cabinet, and the actual protection effect is poor. Summary of the invention

[0005] The object of the present invention is to provide an explosion-proof and flame-retardant electrical control cabinet that can be efficiently clustered to solve the problems raised in the above-mentioned background technology.

[0007] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Fig. 9 As shown, when the line needs to be straightened, the fixed sleeve and the movable sleeve are pulled out of the protective cover so that the magnetic sheet is separated from the movable sleeve. As the movable plate moves down along the slide groove, the fixed sleeve and the movable sleeve move to the middle position of the cabinet, and the wires are placed on the wire clamp mechanisms distributed up and down. The control rod at the back of the corresponding fixed sleeve is manually rotated so that the No. 3 hole on the control plug is aligned with the No. 2 hole, and the air supply mechanism is started so that the gas enters the control sleeve through the distribution mechanism, and enters the No. 2 pipe through the annular groove and the No. 3 hole, and then passes through the air hole and the through hole, and pushes the step rod to move. As the spring is stretched, the movable sleeves on the upper and lower sides move, so that the upper and lower holes are aligned. The wires between the groups of wire clamp mechanisms are arranged in an orderly manner inside, and then the gas enters into the movable sleeve through the through hole, and enters into the elastic air bag through the ventilation pipe of the wire clamp mechanism, so that the wires are stably clamped in the wire clamp mechanism, and then the control lever and the control plug are rotated according to the length of the wires, so that the No. 3 hole is connected with the No. 1 hole. At this time, the air enters into the fixed tube through the No. 1 tube, and pushes the push rod to move, so that the push rod drives the limit frame to push the wires to move outward, so that the wires that are too long are gradually gathered to the middle, and the wires with excess length are tightened between the upper and lower groups of wire clamp mechanisms, and there are no dragging and freely shaking wires in the cabinet.

[0008] Firstly, the air supply mechanism is used to provide power air, and the position of hole No. 3 is controlled by the control plug in the control sleeve. The air supply direction is changed by switching the connection between hole No. 3 and hole No. 1 and hole No. 2. When connected with hole No. 2, the wire clamp mechanism is extended up and down, and the length is expanded when the wires are bundled. The elastic airbag in the wire clamp mechanism is expanded by the introduced air to achieve the limited clamping of the wires. When hole No. 3 is connected with hole No. 1, the introduced air is used to push the middle push rod to move, thereby pushing the wires from the middle of the wires to the outside for tensioning, expanding the length of the whole bundle of wires, and making the wires with excess length at both ends converge toward the middle, thereby improving the whole bundle effect and avoiding the dragging of local wires, which greatly improves the actual use effect of wire wholeness.

[0009] In addition, by opening a slide groove on the inner side of the cabinet, cooperating with the magnetic plate in the slide groove, and utilizing the magnetic sheet inside the protective cover, the fixed sleeve and movable sleeve for the entire bundle can be moved up and down along the cabinet, and when arranging the interior of the electrical cabinet, the fixed sleeve and movable sleeve for the entire line are located in the protective cover, thereby increasing the actual operating space. When needed, with the adsorption effect of the magnetic plate and the metal movable plate, it can be adjusted to a suitable position in the cabinet to improve ease of use.

[0010] Preferably, the inner surface of the movable sleeve is fixedly connected with a step rod, the outer surface of the step rod is movably connected with the through hole, a spring is fixedly connected between the inner surface of the movable sleeve and the fixed sleeve, the air hole is connected with the through hole, and the air hole is connected with the No. 2 tube. By utilizing the step rod to be connected with the through hole, it is ensured that when gas is introduced, the movable sleeves distributed up and down are first pushed to unfold, thereby expanding the length of the entire line, and the gas is introduced into the interior of the movable sleeve after unfolding, and the ventilation pipe of the wire clamp mechanism is cooperated to realize the filling of the gas into the elastic airbag to complete the clamping of the wire clamp.

[0011] Preferably, the outer surface of the control sleeve is provided with hole No. 1 and hole No. 2, respectively. The hole No. 1 is connected to the tube No. 1, the hole No. 2 is connected to the tube No. 2, and the hole No. 3 is connected to the annular groove. By changing the connectivity between hole No. 3 and hole No. 1 as well as hole No. 2, the air supply direction is changed, and the annular groove is utilized to ensure that the air introduced is effectively distributed on both sides.

[0012] Preferably, the wire clamp mechanism includes a wire clamp, a mounting groove, an elastic airbag, a limit frame and a ventilation tube, the wire clamp is fixedly connected to the front side of the movable sleeve, the mounting groove is opened on the side of the wire clamp, the elastic airbag is fixedly sleeved inside the mounting groove, the limit frame is fixedly connected to the side of the wire clamp and is located on the outside of the elastic airbag, the ventilation tube is fixedly connected to the side of the limit frame and is connected to the elastic airbag, and the lower end of the ventilation tube is connected to the movable sleeve. By utilizing the inflation of the elastic airbag, the clamping and limiting of the wires are achieved, the stability of the entire bundle is ensured, and damage to the surface of the wires is avoided. The damping force actually provided allows the subsequent push rod to push the middle part of the wire to tighten.

[0013] Preferably, a slide groove is provided on the inner surface of the cabinet, a magnetic plate is fixedly connected to the surface of the slide groove, a connecting rod is fixedly connected to the side of the fixed sleeve, a movable plate is fixedly connected to the outer end of the connecting rod, and the movable plate is movably sleeved inside the slide groove and adsorbed to the magnetic plate. By utilizing the movable plate to be movably sleeved with the slide groove and adsorbed to the magnetic plate, the fixed sleeve and the movable sleeve are supported to be stable in the cabinet by a strong magnetic effect, and the actual position can be adjusted conveniently, thereby improving convenience of use.

[0014] Preferably, a top opening is opened on the top surface of the cabinet, and a protective cover is fixedly installed on the top surface of the cabinet. The protective cover is located on the outside of the air supply mechanism, and a magnetic sheet is provided on the top surface of the inner surface of the protective cover. The magnetic sheet is adsorbed and fixed with the movable cover on the top, so that the fixed cover and the movable cover for the whole line can be moved into the protective cover in a non-line-integrated state to achieve hiding and storage, thereby providing sufficient operating space for the cabinet.

[0015] Preferably, the air supply mechanism includes an air pump, an air box and an intermediate pipe, the air pump and the air box are both fixedly mounted on the top surface of the cabinet, the intermediate pipe is fixedly connected between the air pump and the air box, the air box is filled with carbon dioxide gas, and by pumping in stable gases such as carbon dioxide, the driving force is achieved while participating in the fire extinguishing of the cabinet.

[0016] Preferably, the distribution mechanism includes a connecting pipe, a distribution sleeve and an air pipe, the connecting pipe is fixedly connected to the end face of the control sleeve, the distribution sleeve is fixedly connected to the end face of the connecting pipe, and the air pipe is fixedly connected between the distribution sleeve and the air pump. The gas in the air supply mechanism is distributed to each group of control sleeves by utilizing the distribution mechanism, and the control plugs in each group of control sleeves can be individually controlled to achieve the arrangement of each group of wire harnesses, so that reasonable wiring can be carried out to adapt to the lengths of different wire harnesses.

[0017] Preferably, the front of the gas box is fixedly connected with a curved pipe, the lower end of the curved pipe is located inside the cabinet, and the lower end of the curved pipe is fixedly sleeved with a fuse plug, which is an indium tin lead bismuth alloy and is soluble at about °. When combustion occurs inside the cabinet, it can be dissolved and the seal of the curved pipe can be released, thereby discharging carbon dioxide gas.

[0018] like Figure 1 , Figure 2 , Figure 7 and Fig.10 As shown, when combustion or the like occurs inside the cabinet, the temperature inside the cabinet rises rapidly. As the temperature rises, the fuse plug at the lower end of the curved tube melts due to the heat. As the fuse plug melts, the seal of the curved tube is released, causing the air box in the air supply mechanism to release internal carbon dioxide through the curved tube. As the carbon dioxide is sprayed into the interior of the cabinet, the oxygen is consumed by the local internal combustion, causing the oxygen content inside the cabinet to decrease rapidly and the carbon dioxide concentration to increase, thereby automatically extinguishing the burning point.

[0019] Firstly, by utilizing the carbon dioxide gas filled in the air box in the air supply mechanism, and using a curved tube to fix the connection with the air box, and using a low-melting-point fuse plug to seal the curved tube, the lower end of the flexible curved tube is moved to the inside of the cabinet when in use. When combustion occurs inside the electrical control cabinet, as the temperature inside the cabinet rises, the fuse plug at the lower end of the curved tube quickly melts, thereby releasing the seal of the curved tube, and then discharging the carbon dioxide in the air box, realizing rapid fire extinguishing inside the cabinet, greatly improving self-service fire extinguishing, and realizing autonomous fire extinguishing when an alarm is sounded to notify patrol personnel, with good use effect.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The present invention uses an air supply mechanism to provide power air, and uses a control plug in a control sleeve to control the position of hole No. 3. By switching the connection between hole No. 3 and hole No. 1 and hole No. 2, the air supply direction is changed. When connected with hole No. 2, the wire clamp mechanism is extended up and down, and the length is expanded during the bundle. The elastic airbag in the wire clamp mechanism is expanded by the introduced air to achieve the limited clamping of the wire. When hole No. 3 is connected with hole No. 1, the introduced air is used to push the middle push rod to move, thereby pushing the wire from the middle of the wire to the outside for tensioning, expanding the length of the whole bundle of the wire, and making the wires with excess length at both ends converge toward the middle, thereby improving the bundle effect, avoiding the dragging of local wires, and greatly improving the actual use effect of wire wholeness.

[0022] 2. The present invention opens a slide groove on the inner side of the cabinet, cooperates with the magnetic plate in the slide groove, and utilizes the magnetic sheet inside the protective cover, so that the fixed sleeve and the movable sleeve for the whole bundle can move up and down along the cabinet, and when arranging the interior of the electrical cabinet, the fixed sleeve and the movable sleeve for the whole line are located in the protective cover, thereby increasing the actual operating space. When needed, with the adsorption effect of the magnetic plate and the metal movable plate, they can be adjusted to a suitable position in the cabinet to improve ease of use.

[0023] 3. The present invention utilizes the carbon dioxide gas filled in the air box in the air supply mechanism, and uses a curved tube to be fixedly connected with the air box, and uses a low-melting-point fuse plug to seal the curved tube. When in use, the lower end of the flexible curved tube is moved to the inside of the cabinet. When combustion occurs inside the electrical control cabinet, as the temperature inside the cabinet rises, the fuse plug at the lower end of the curved tube quickly melts, thereby releasing the seal of the curved tube, and then discharging the carbon dioxide in the air box, realizing rapid fire extinguishing inside the cabinet, greatly improving self-service fire extinguishing, and realizing self-extinguishing when an alarm is issued to notify patrol personnel, with good use effect.

[0048] Embodiment 3: Figure 1 , Figure 2 , Figure 7 and Fig.10 As shown, when combustion or the like occurs inside the cabinet 1, the temperature inside the cabinet 1 rises rapidly. As the temperature rises, the fuse plug 27 at the lower end of the curved tube 26 is melted by the heat. As the fuse plug 27 melts, the seal of the curved tube 26 is released, so that the gas box 232 in the gas supply mechanism 23 releases internal carbon dioxide through the curved tube 26.

[0049] Firstly, by utilizing the carbon dioxide gas filled in the air box 232 in the air supply mechanism 23, and by using the curved tube 26 to be fixedly connected with the air box 232, and by using the low melting point fuse plug 27 to seal the curved tube 26, when in use, the lower end of the flexible curved tube 26 is moved to the inside of the cabinet 1. When combustion occurs inside the electrical control cabinet, as the temperature inside the cabinet 1 rises, the fuse plug 27 at the lower end of the curved tube 26 melts quickly, thereby releasing the seal of the curved tube 26, and then discharging the carbon dioxide in the air box 232, realizing rapid fire extinguishing inside the cabinet 1, greatly improving self-service fire extinguishing, and realizing self-service fire extinguishing when an alarm is sounded to notify patrol personnel, with good use effect.
