DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] See also Figure 1 , Figure 2 and Figure 4The present invention provides an automatic interlocking safety control cabinet, which includes a cabinet 1, a bottom side wall of the cabinet 1 is provided with a heat dissipation port, and a control panel 16 is rotatably connected inside the heat dissipation port. By adjusting the control panel 16, the heat dissipation port is blocked, thereby ensuring the sealing effect inside the cabinet 1. When an abnormal open fire occurs inside the cabinet 1, the interior is isolated from the external oxygen by sealing, thereby achieving the effect of isolating oxygen for fire extinguishing. A nozzle is provided on the top of the cabinet 1, a hydraulic channel is provided on the side wall inside the cabinet 1, and a control channel 7 connected to the hydraulic channel is provided on the side wall inside the cabinet 1. A control component for controlling the opening and closing of the control panel 16 and the nozzle communication channel is slidably provided inside the control channel 7, thereby ensuring that the control component can control the nozzle when an abnormal state occurs inside the cabinet 1. The state of the nozzle and the control panel 16 ensures that the abnormal state of the cabinet 1 is automatically processed specifically to reduce the time delay of the processing. The control component switches the incoming gas of the nozzle when the internal temperature of the cabinet 1 rises to a certain value, and blocks the heat dissipation port when the temperature continues to rise, ensuring that the interior of the cabinet 1 is isolated from the external oxygen at this time to prevent the fire from further spreading; the cover plate 3 connected to the cabinet 1 is rotated, and the cover plate 3 is connected to the control component and resets the control panel 16 and the nozzle to the initial position when the cover plate 3 is opened, so that when the cover plate 3 is opened manually, the control panel 16 and the nozzle are reset at this time, thereby ensuring that the gas enters the interior of the cabinet 1 from multiple directions to prevent the fire from bursting from the cover plate 3 and causing harm to the operator. A handle 2 that is easy to operate is provided on the cover plate 3 to facilitate the opening and closing of the cover plate 3.

[0020] Preferably, the control channel 7 of the present invention is arranged in the middle section of the hydraulic channel, and the control panel 16 and the nozzle are respectively connected to the two ends of the hydraulic channel, so that the states of the control panel 16 and the nozzle can be directly controlled through the control channel 7. The interior of the hydraulic channel is provided with a thermal expansion liquid 13 (the type of thermal expansion liquid is selected in the prior art and will not be described in detail). The control member controls the filling space size of the thermal expansion liquid 13 to ensure that when the cover plate 3 is opened, the filling space is increased at this time, and the force of the thermal expansion liquid 13 no longer acts on the control panel 16 and the nozzle, so that the control panel 16 and the nozzle are reset to prevent harm to the operator. The control component includes: a rotating A pull rod 5 connected to the cover plate 3; a sliding rod 6 slidably connected to the inside of the control channel 7, the pull rod 5 is rotatably connected to the sliding rod 6, the rotation of the cover plate 3 drives the pull rod 5 to pull the sliding rod 6 to slide inside the control channel 7, and the cover plate 3 is associated with the pull rod 5 to automatically reset the nozzle and the control board 16, and the sliding rod 6 moves to adjust the filling space size of the thermal expansion liquid 13, so that when the cover plate 3 is reset and locked, the size of the filling space is fixed by the locking force of the cover plate 3, thereby ensuring the locking association between the cover plate 3 and the filling space size, preventing the state of the nozzle and the sealing plate from changing when the cover plate 3 is not locked.

[0021] In addition, the thermal expansion liquid 13 of the present invention is provided with a top sliding core 12 and a bottom sliding core 14 at both ends of the hydraulic channel. The top sliding core 12 and the bottom sliding core 14 slide to control the state of the nozzle and the control panel 16, so as to promptly deal with the abnormal state inside the cabinet 1. The hydraulic channel is provided with a limiting convex edge that cooperates with the top sliding core 12 and the bottom sliding core 14. The limiting convex edge limits the sliding position of the top sliding core 12 and the bottom sliding core 14. The bottom sliding core 14 slides to adjust the inclination angle of the control panel 16 to ensure that when the interior of the cabinet 1 needs to be isolated and sealed, the angle of the control panel 16 can be adjusted by sliding the bottom sliding core 14, so as to ensure the sealing of the heat dissipation port. The top sliding core 12 slides to adjust the communication channel of the nozzle. When an abnormal ignition point appears inside the cabinet 1, the connection channel of the nozzle can be switched to supply gas with cooling or fire extinguishing effect to the interior, so as to ensure cooling or fire extinguishing of the cabinet 1.

[0022] See also Figure 1~Figure 5Furthermore, a connector is provided on the outer side of the top of the cabinet 1 of the present invention, and the connector includes three communication channels, which are respectively an air intake channel 10, a cooling channel 9 and a switching channel 8. The initial state of the connector is that the nozzle is connected to the air intake channel 10. At this time, the cabinet 1 is in a normal state, so that air is supplied to the interior through the nozzle, and then exhausted through the heat dissipation port to dissipate heat for the cabinet 1. The top sliding inner core 12 slides to switch the connection relationship between the nozzle and the air intake channel 10 and the cooling channel 9, and a guide portion 101 is provided in the air intake channel. , ensuring that the air can better enter the interior, ensuring that when the cabinet 1 is abnormal, different gases can be supplied to the interior of the cabinet 1 by means of the switching channel 8, the switching channel 8 is connected to the hydraulic channel, and the interior of the connecting head is provided with a switching head 11 slidably connected to the switching channel 8, the switching head 11 blocks the cooling channel 9 when retracting into the switching channel 8, this is the initial state of the switching head 11, and the air inlet channel 10 is blocked when extending out of the switching channel 8, this is the working state of the switching head 11, and also the state in which an abnormality occurs inside the cabinet 1.

[0023] See also Figure 1 to Figure 8 Preferably, a hydraulic fluid is arranged between the switching head 11 of the present invention and the top sliding inner core 12 inside the hydraulic channel. The top sliding inner core 12 slides to push the hydraulic fluid to transmit the driving force to the switching head 11, thereby realizing the switching of the nozzle connecting channel. The top sliding inner core 12 slides to control the switching head 11 to slide inside the switching channel 8. The switching head 11 includes a sliding portion 113 slidably connected to the inside of the switching channel 8. The sliding portion 113 is a shaft structure to ensure that the switching channel 8 can be sealed to prevent leakage of the hydraulic fluid. The arc-shaped sealing portion 111 for sealing the cooling channel 9 and the square sealing portion 112 for sealing the air intake channel 10 are arranged at the end of the sliding portion 113. By switching the positions of the arc-shaped sealing portion 111 and the square sealing portion 112, it is ensured that the switching head 11 can be controlled to seal the air intake channel 10 or the cooling channel 9, thereby realizing the control of the spray of the nozzle.

[0024] Furthermore, a thrust spring 15 is provided between the bottom of the bottom sliding inner core 14 and the hydraulic channel of the present invention, and the thrust spring 15 ensures the reset force of the bottom sliding inner core 14, so that when the thermal expansion liquid 13 acts, the top sliding inner core 12 can be pushed to move first, and then the bottom sliding inner core 14 can be controlled to move, so as to realize the sequential control of the control of the nozzle and the control panel 16. The sliding of the bottom sliding inner core 14 drives the control panel 16 to rotate between 0° and 90° with the side wall of the control cabinet, so as to prevent the rotation angle of the control panel 16 from being too large, thereby affecting the service life of the control panel 16. The control panel 16 includes an inner portion rotatably connected to the heat dissipation port. The end of the rotating shaft 162 is provided with a partial gear 161 at one end cooperating with the bottom sliding inner core, and the partial gear 161 is a quarter gear to ensure that the rotating shaft 162 is controlled to rotate 90°. The bottom sliding inner core 14 is provided with a rack 141 meshing with the partial gear 161, and the movement of the rack 141 drives the rotating shaft 162 to rotate. The control board 16 is provided with a groove 163 cooperating with the rotating shaft 162, and the sliding control groove 163 of the bottom sliding inner core 14 is clamped and closed with the rotating shaft 162 of the adjacent control board 16, ensuring that multiple control boards 16 cooperate, and the heat dissipation port can be fully blocked and sealed.

[0025] In this embodiment, combined with Figure 1 to Figure 8 When in use, when the cover plate 3 is opened, the pull rod 5 rotates synchronously with the cover plate 3 through the pulling force of the hinge seat 4 on the cover plate 3, and the pull rod 5 drives the sliding rod 6 to slide to the outside of the control channel. At this time, the filling space of the thermal expansion liquid 13 increases, and the thermal expansion liquid 13 no longer exerts force on the bottom sliding inner core 14 and the top sliding inner core 12, and the bottom sliding inner core 14 and the top sliding inner core 12 are reset to the initial position by the negative pressure force, and the switching head 11 is restored to the state of blocking the cooling channel 9 by the force, and the control board 16 is in the state of fully opening the heat dissipation port under the action of the bottom sliding inner core 14; When the cover plate 3 is closed, it is necessary to lock the cover plate 3 (directly use the traditional cabinet door lock, the prior art, no further description is needed), the pull rod 5 is forced to push the sliding inner core inward, and push it to a state where the heat expansion liquid 13 is not forced. At this time, the top sliding inner core 12 and the bottom sliding inner core 14 are still in the initial state, and then when the abnormal temperature increases inside the cabinet 1, before the temperature increases to a certain value, the heat expansion liquid 13 expands due to the heat, and the bottom sliding inner core 14 does not move due to the action of the thrust spring 15, and the top sliding inner core 12 moves first, gradually pushing the switching head 11, and the nozzle is gradually connected with the cooling channel 9, and the cooling channel 9 supplies cooling oxygen-free to the interior. When the temperature inside the cabinet 1 continues to rise, it is determined to be on fire. The thermal expansion liquid 13 continues to expand, and the bottom sliding core 14 is forced to slide toward the bottom, turning the control panel 16 to block the heat dissipation port. At this time, the cabinet 1 is in a sealed state, ensuring that the internal ignition point of the cabinet 1 is isolated from the external oxygen, thereby extinguishing the fire. Then, when the operator needs to open the operation, the nozzle and the control panel 16 are reset, and more gas enters the cabinet 1, preventing the single gas entering the cover 3 of the cabinet 1 from causing harm to the operator due to the internal gas or the ignition point.

[0026] In summary, the present invention provides an automatic interlocking safety control cabinet, comprising: a cabinet, a bottom side wall of the cabinet is provided with a heat dissipation port, the heat dissipation port is rotatably connected to a control panel, the heat dissipation port is sealed by adjusting the control panel, thereby ensuring the sealing effect inside the cabinet, and when an abnormal open fire occurs inside the cabinet, the interior is isolated from external oxygen by sealing, thereby achieving the effect of isolating oxygen for fire extinguishing, a nozzle is provided on the top of the cabinet, a hydraulic channel is provided on the side wall inside the cabinet, a control channel connected to the hydraulic channel is provided on the side wall inside the cabinet, and a control component for controlling the opening and closing of the control panel and the nozzle communication channel is provided inside the control channel, thereby ensuring that the control component can control the state of the nozzle and the control panel when an abnormal state occurs inside the cabinet, thereby ensuring that the abnormal state of the cabinet is automatically processed in a specific manner, reducing the processing The control component switches the incoming gas of the nozzle when the temperature inside the cabinet rises to a certain value, and blocks the heat dissipation port when the temperature continues to rise, thereby ensuring that the interior of the cabinet is isolated from the external oxygen at this time, preventing the fire from further spreading; rotating the cover plate connected to the cabinet, the cover plate is connected to the control component and resets the control panel and the nozzle to the initial position when the cover plate is opened, so that when the cover plate is opened manually, the control panel and the nozzle are reset at this time, thereby ensuring that gas enters the interior of the cabinet from multiple directions, preventing the fire from exploding from the cover plate and causing harm to the operator.
