Detailed implementation manners

[0028] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to 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 used to limit the present invention.

[0029] See Figure 1 、 Figure 2 and Figure 4, the present invention provides an automatic interlocking safety control cabinet. The automatic interlocking safety control cabinet includes a cabinet body 1. A heat dissipation port is provided on the bottom side wall of the cabinet body 1. A control board 16 is rotatably connected inside the heat dissipation port. By adjusting the control board 16, the heat dissipation port is blocked to ensure the sealing effect inside the cabinet body 1. When an abnormal open fire appears inside the cabinet body 1, the inside is isolated from the outside oxygen through sealing, achieving the function of isolating oxygen for fire extinguishing. A nozzle is provided on the top of the cabinet body 1. A hydraulic channel is provided on the side wall inside the cabinet body 1. A control channel 7 communicating with the hydraulic channel is provided on the side wall inside the cabinet body 1. A control component for controlling the opening and closing of the control board 16 and the communication channel of the nozzle is slidably provided inside the control channel 7, so as to ensure that the control component can control the states of the nozzle and the control board 16 when an abnormal state appears inside the cabinet body 1, ensuring that the abnormal state of the cabinet body 1 is automatically processed in a specific manner and reducing the time delay of processing. When the temperature inside the cabinet body 1 rises to a certain value, the control component switches the gas entering the nozzle, and when the temperature continues to rise, the heat dissipation port is blocked to ensure that the inside of the cabinet body 1 is isolated from the outside oxygen at this time and prevent the fire from spreading further; a cover plate 3 rotatably connected to the cabinet body 1, the cover plate 3 is connected to the control component and resets the control board 16 and the nozzle to the initial position when the cover plate 3 is opened. Thus, when the cover plate 3 is manually opened, the control board 16 and the nozzle are reset at this time, so as to ensure that gas enters the inside of the cabinet body 1 from multiple directions and prevent the fire from exploding from the cover plate 3 and causing harm to the operator. A handle 2 convenient for operation is provided on the cover plate 3 to facilitate the opening and closing of the cover plate 3.

[0030] Preferably, the control channel 7 of the present invention is arranged in the middle section of the hydraulic channel. The control board 16 and the nozzle are respectively communicated with both ends of the hydraulic channel, ensuring that the states of the control board 16 and the nozzle can be directly controlled through the control channel 7. There is a thermally expandable liquid 13 inside the hydraulic channel (the selection of the type of thermally expandable liquid is prior art and will not be elaborated here). The control member controls the size of the filling space of the thermally expandable liquid 13. When the cover plate 3 is opened, the filling space increases at this time, and the force of the thermally expandable liquid 13 no longer acts on the control board 16 and the nozzle, causing the control board 16 and the nozzle to reset and preventing harm to the operator. The control assembly includes: a pull rod 5 rotatably connected to the cover plate 3; a sliding rod 6 slidably connected inside the control channel 7. The pull rod 5 is rotatably connected to the sliding rod 6. When the cover plate 3 rotates, it drives the pull rod 5 to pull the sliding rod 6 to slide inside the control channel 7. Through the association between the cover plate 3 and the pull rod 5, the nozzle and the control board 16 are automatically reset. The sliding rod 6 moves to adjust the size of the filling space of the thermally expandable liquid 13. When the cover plate 3 is reset and locked, at this time, through the locking force of the cover plate 3, the size of the filling space is fixed, thereby ensuring the locking association between the cover plate 3 and the size of the filling space and preventing the states of the nozzle and the plugging plate from changing when the cover plate 3 is not locked.

[0031] In addition, at both ends of the hydraulic channel where the thermally expandable liquid 13 of the present invention is located, there are a top sliding inner core 12 and a bottom sliding inner core 14. By the sliding of the top sliding inner core 12 and the bottom sliding inner core 14, the states of the nozzle and the control board 16 are controlled, so as to timely handle the abnormal state inside the cabinet body 1. There are limiting convex edges inside the hydraulic channel that cooperate with the top sliding inner core 12 and the bottom sliding inner core 14 to limit the sliding positions of the top sliding inner core 12 and the bottom sliding inner core 14. The bottom sliding inner core 14 slides to adjust the inclination angle of the control board 16, ensuring that when it is necessary to isolate and seal the inside of the cabinet body 1, the angle of the control board 16 can be adjusted by the sliding of the bottom sliding inner core 14, thereby ensuring the sealing of the heat dissipation port. The top sliding inner core 12 slides to adjust the communication channel of the nozzle. When there is an abnormal ignition point inside the cabinet body 1, the connection channel of the nozzle can be switched, so as to supply gas with a cooling or fire extinguishing effect to the inside, ensuring the cooling or fire extinguishing of the cabinet body 1.

[0032] See Figures 1 to 5, Further, a connector is provided on the outer side of the top of the cabinet body 1 of the present invention. The connector includes three communication channels, namely an air inlet channel 10, a cooling channel 9, and a switching channel 8. The initial state of the connector is a state where the nozzle is in communication with the air inlet channel 10. At this time, the cabinet body 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 from the cabinet body 1. The top sliding inner core 12 slides to switch the communication relationship between the nozzle and the air inlet channel 10 and the cooling channel 9. At the same time, a diversion part 101 is provided in the air inlet channel to ensure that air can enter the interior better. It is ensured that when the cabinet body 1 is abnormal, different gases can be supplied to the interior of the cabinet body 1 by means of the switching channel 8. The switching channel 8 is in communication with the hydraulic channel. A switching head 11 slidably connected to the switching channel 8 is provided inside the connector. When the switching head 11 retracts into the switching channel 8, the cooling channel 9 is blocked. This is the initial state of the switching head 11. When it extends out of the switching channel 8, the air inlet channel 10 is blocked. This is the working state of the switching head 11 and also the state when an abnormality occurs inside the cabinet body 1.

[0033] See Figures 1 to 8 , Preferably, a hydraulic fluid is provided 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, pushing the hydraulic fluid to transmit the driving force to the switching head 11, thereby realizing the switching of the communication channels of the nozzle. The top sliding inner core 12 slides to control the sliding of the switching head 11 inside the switching channel 8. The switching head 11 includes a sliding part 113 slidably connected to the inside of the switching channel 8. The sliding part 113 is a shaft structure to ensure that the switching channel 8 can be sealed to prevent the leakage of hydraulic fluid. An arc-shaped sealing part 111 for sealing the cooling channel 9 and a square sealing part 112 for sealing the air inlet channel 10 are provided at the end of the sliding part 113. By switching the positions of the arc-shaped sealing part 111 and the square sealing part 112, it is ensured that the switching head 11 can control the sealing of the air inlet channel 10 or the cooling channel 9, thereby realizing the control of the ejecta of the nozzle.

[0034] Furthermore, a thrust spring 15 is provided between the bottom of the bottom sliding inner core 14 of the present invention and the hydraulic passage. The thrust spring 15 ensures the restoring force of the bottom sliding inner core 14, ensuring that when the thermally expandable liquid 13 acts, it can first push the top sliding inner core 12 to move, and then control the bottom sliding inner core 14 to move, realizing the sequence control of the control of the nozzle and the control board 16. The sliding of the bottom sliding inner core 14 drives the control board 16 to rotate between 0° and 90° with the side wall of the control cabinet, preventing the rotation angle of the control board 16 from being too large and affecting the service life of the control board 16. The control board 16 includes a rotating shaft 162 rotatably connected to the inside of the heat dissipation port. One end of the rotating shaft 162 that cooperates with the bottom sliding inner core is provided with a partial gear 161. The partial gear 161 is a quarter gear, ensuring that the rotating shaft 162 rotates 90°. A rack 141 meshing with the partial gear 161 is provided on the bottom sliding inner core 14. The movement of the rack 141 drives the rotating shaft 162 to rotate. A groove 163 cooperating with the rotating shaft 162 is provided on the control board 16. The sliding of the bottom sliding inner core 14 controls the groove 163 to be clamped and closed with the rotating shaft 162 of the adjacent control board 16, ensuring that multiple control boards 16 cooperate to fully block and seal the heat dissipation port.

[0035] In this embodiment, combined with Figures 1 to 8 , when in use, when the cover plate 3 is opened, at this time, the pull rod 5 rotates synchronously with the cover plate 3 under the pulling force of the hinge seat 4 on the cover plate 3. At the same time, the pull rod 5 drives the sliding rod 6 to slide outward to the control channel. At this time, the filling space of the thermally expandable liquid 13 increases, and the thermally expandable liquid 13 no longer exerts a 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 under the negative pressure force. The switching head 11 is restored to the state of blocking the cooling channel 9 under force, and the control board 16 is fully opened to the heat dissipation port under the action of the bottom sliding inner core 14;

[0036] When the cover plate 3 is closed, it is necessary to lock the cover plate 3 at this time (directly using a traditional cabinet lock, which is prior art and will not be elaborated further). The pull rod 5 is stressed to push the sliding inner core inward, until the thermal expansion liquid 13 is in a state of not being stressed. At this time, the top sliding inner core 12 and the bottom sliding inner core 14 are still in their initial states. Then, when the temperature inside the cabinet 1 abnormally increases, before the temperature increases to a certain value, the thermal expansion liquid 13 expands due to heat. The bottom sliding inner core 14 will not move under 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 gradually communicates with the cooling channel 9. The cooling channel 9 supplies cooled oxygen-free gas (or cooled inert gas) to the inside. When it is determined that the cabinet 1 is on fire because the temperature inside the cabinet 1 continues to rise, the thermal expansion liquid 13 continues to expand, and the bottom sliding inner core 14 is stressed to slide downward, turning the control board 16 to a state of blocking 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 achieving fire extinguishing at the ignition point. Then, when the operator needs to open and operate, the nozzle and the control board 16 are reset, and gas enters the inside of the cabinet 1 more, preventing the single gas entry at the cover plate 3 of the cabinet 1 from causing harm to the operator due to the internal gas or the ignition point.

[0037] In summary, the present invention provides an automatic interlocking safety control cabinet, including: a cabinet body, a heat dissipation port is provided on the bottom side wall of the cabinet body, a control board is rotatably connected inside the heat dissipation port, and by adjusting the control board, the heat dissipation port can be blocked to ensure the sealing effect inside the cabinet body. When an abnormal open fire occurs inside the cabinet body, the inside is isolated from the outside oxygen through sealing, achieving the effect of isolating oxygen for fire extinguishing. A sprinkler is provided on the top of the cabinet body, a hydraulic channel is provided on the side wall inside the cabinet body, a control channel communicating with the hydraulic channel is provided on the side wall inside the cabinet body, and a control component for controlling the opening and closing of the control board and the communication channel of the sprinkler is slidably provided inside the control channel, so as to ensure that the control component can control the states of the sprinkler and the control board when an abnormal state occurs inside the cabinet body, ensuring that the abnormal state of the cabinet body can be automatically processed in a specific manner and reducing the time delay of the processing. When the temperature inside the cabinet body rises to a certain value, the control component switches the gas entering the sprinkler, and blocks the heat dissipation port when the temperature continues to rise, ensuring that the inside of the cabinet body is isolated from the outside oxygen at this time and preventing the fire from spreading further; a cover plate rotatably connected to the cabinet body, the cover plate is connected to the control component and resets the control board and the sprinkler to the initial position when the cover plate is opened. Thus, when the cover plate is manually opened, the control board and the sprinkler are reset at this time, ensuring that gas enters the inside of the cabinet body from multiple directions and preventing the fire from exploding from the cover plate and causing harm to the operator. In summary, the technical effect produced by the present invention is to ensure that when overheating or an open fire occurs inside the control cabinet, the internal state is processed through its own protection mechanism, thereby ensuring the safety of the control cabinet.
