[0046] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0047] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0048] Example 1
[0049] Reference Figure 1~Figure 5 , is the first embodiment of the utility model, which provides a fire spread prevention frame, including,
[0050] The supporting mechanism 100 includes a column 101, an electromagnetic fixed valve 102 adapted to be installed on the outside of the column 101, and an installation box 103 fixedly connected to the top of the column 101, a first cavity 104 is opened inside the installation box 103, a second cavity 105 is opened inside the installation box 103, a winding component 106 is arranged on the outside of the column 101, a trigger component 107 is adapted to be installed inside the column 101, an auxiliary component 108 is adapted to be installed inside the installation box 103, and an opening and closing component 109 is arranged inside the installation box 103.
[0051] Specifically, the winding component 106 includes a motor 106a adapted to be installed on the outside of the column 101, a winding shaft 106b fixedly connected to the output end of the motor 106a, and a fireproof cloth 106c arranged on the outside of the winding shaft 106b, one end of the fireproof cloth 106c is fixedly connected to a bottom rod 106d, both ends of the bottom rod 106d are fixedly connected to counterweight blocks 106e, and the outside of the winding shaft 106b is fixedly connected to an outer ring 106f;
[0052] The outer side of the outer ring 106f is provided with convex strips, and the convex strips are provided with at least 6 groups, and the convex strips are evenly distributed on the outer side of the outer ring 106f, and the electromagnetic fixed valve 102 is clamped with the counterweight block 106e.
[0053] Furthermore, the trigger component 107 includes an inner cavity 107a opened at the bottom end of the column 101, a first spring 107b fixedly connected to the bottom end of the inner cavity 107a, and a top rod 107c fixedly connected to the top end of the first spring 107b, a support rod 107d is slidably connected to the inner cavity 107a, and a top ring 107e is fixedly connected to the top end of the support rod 107d;
[0054] Among them, a second spring 107f is sleeved on the outer side of the push rod 107c, a transmission assembly 107g is set at the top of the push rod 107c, one end of the second spring 107f is fixedly connected to the inner bottom end of the column 101, and the other end is fixedly connected to the bottom end of the counterweight block 106e, and the interior of the inner cavity 107a is filled with hydraulic oil.
[0055] When in use, the first chamber 104 of the installation box 103 needs to be filled with dry powder. When a fire occurs in the transformer and the fire spread prevention frame is activated, the electromagnetic fixed valve 102 will be automatically opened to cancel the limit fixation of the counterweight block 106e. At this time, under the weight of the counterweight block 106e, the fireproof cloth 106c will be stretched downward, and the reel 106b will be driven to rotate continuously until the fireproof cloth 106c is completely opened. At this time, the fireproof cloth 106c spread out on all four sides of the transformer can block the fire;
[0056] When the electromagnetic fixing valve 102 cancels the limit fixation on the counterweight block 106e, the elastic tension of the second spring 107f will increase the speed at which the counterweight block 106e slides down inside the column 101, thereby increasing the speed at which the fireproof cloth 106c is deployed.
[0057] In summary, by being able to quickly unfold the fireproof cloth 106c, the burning transformer can be effectively isolated from other normal electrical appliances, which can not only reduce the speed of fire spread, but also provide certain protection for normal electrical appliances and reduce the losses caused by the fire. At the same time, the burning equipment can be isolated from the air to control the fire.
[0058] Example 2
[0059] Reference Figure 1 to Figure 12 , which is the second embodiment of the utility model, is based on embodiment 1 and provides a transmission assembly 107g, including a connecting frame 107g-1 fixedly connected to the top of the top rod 107c, and a connecting rod 107g-2 fixedly connected to the top of the connecting frame 107g-1, and the bottom end of the connecting rod 107g-2 passes through the connecting frame 107g-1 and is located at the inner upper end of the connecting frame 107g-1.
[0060] Preferably, the auxiliary component 108 includes a round rod 108a slidably connected to the bottom end of the installation box 103, an inclined plate 108b fixedly connected to the top of the round rod 108a, and a partition 108c fixedly connected to the bottom end of the inclined plate 108b, the partition 108c slides inside the second cavity 105, and a change-of-direction component 108d is provided inside the column 101.
[0061] It should be noted that the direction-changing assembly 108d includes a rotating shaft 108d-1 rotatably connected to the inside of the column 101, a telescopic rod 108d-2 fixedly connected to the outside of the rotating shaft 108d-1, and a first connecting seat 108d-3 fixedly connected to the outside of the connecting frame 107g-1, and a second connecting seat 108d-4 is fixedly connected to the bottom end of the round rod 108a;
[0062] Among them, one end of the telescopic rod 108d-2 is hinged to the first connecting seat 108d-3, and the other end of the telescopic rod 108d-2 is hinged to the second connecting seat 108d-4.
[0063] Preferably, the opening and closing component 109 includes a pressure block 109a slidably connected to the inside of the installation box 103, a short rod 109b fixedly connected to the bottom end of the pressure block 109a, and a plug 109c fixedly connected to the bottom end of the short rod 109b. Side panels 109d are fixedly connected to both sides of the pressure block 109a, and the bottom end of the side panel 109d is fixedly connected to the top end of the connecting rod 107g-2.
[0064] When the fireproof cloth 106c is unfolded and drives the reel 106b to rotate, the rotating reel 106b will drive the outer ring 106f on the outside to rotate continuously, so that the end of the connecting rod 107g-2 located inside the connecting frame 107g-1 can be continuously and intermittently squeezed through the convex strips on the outer side of the outer ring 106f, and then when the connecting rod 107g-2 is squeezed, the connecting rod 107g-2 and the connecting frame 107g-1 will slide up, and the connecting rod 107g-2 and the connecting frame 107g-1 will be squeezed. 2 can drive the side plate 109d and the pressure block 109a at one end of the side plate 109d to slide upward, and the pressure block 109a can drive the plug 109c at the bottom end of the short rod 109b to slide upward, thereby prompting the second chamber 105 to open. When the connecting rod 107g-2 is not squeezed, under the elasticity of the first spring 107b, the connecting frame 107g-1 and the connecting rod 107g-2 will be reset through the push rod 107c, which will drive the pressure block 109a and the plug 109c to reset;
[0065] That is, when the reel 106b drives the outer ring 106f to rotate, the connecting frame 107g-1 and the connecting rod 107g-2 slide back and forth up and down, which drives the pressing block 109a and the plug 109c to slide back and forth up and down continuously;
[0066] The reciprocating sliding of the connecting frame 107g-1 will rotate around the rotating shaft 108d-1 through the cooperation of the first connecting seat 108d-3, the second connecting seat 108d-4 and the telescopic rod 108d-2, and drive the inclined plate 108b at the top of the round rod 108a to move, and the reciprocating direction of the inclined plate 108b is opposite to that of the connecting frame 107g-1, that is, when the pressure block 109a slides upward, the inclined plate 108b moves downward, and vice versa, when the pressure block 109a slides downward, the inclined plate 108b moves upward.
[0067] Through the opposite movement of the pressing block 109a and the inclined plate 108b, the dry powder inside the first chamber 104 can be moved to avoid agglomeration and blockage, and the pressing block 109a and the inclined plate 108b can be quickly dislocated and opened, so that the dry powder inside the first chamber 104 can quickly enter the second chamber 105, and when the pressing block 109a and the inclined plate 108b are dislocated and fitted, the plug 109c is driven to open, and the dry powder inside the second chamber 105 is sprayed on the surface of the fireproof cloth 106c, thereby improving the fireproof effect of the fireproof cloth 106c;
[0068] At the same time, because the pressing block 109a and the inclined plate 108b are misaligned and fitted to spray dry powder, the second chamber 105 generates a relatively sealed space, thereby preventing the dry powder from flowing back when the pressing block 109a squeezes and sprays dry powder, thereby ensuring the effect of dry powder spraying.
[0069] Until the fireproof cloth 106c is completely opened, the counterweight block 106e will fall on the surface of the top ring 107e and press the top ring 107e, prompting the top ring 107e to drive the support rod 107d to squeeze the hydraulic oil inside the inner cavity 107a, thereby prompting the hydraulic oil to squeeze the top rod 107c, prompting the top rod 107c to rise and drive the connecting frame 107g-1 and the connecting rod 107g-2 to rise. At this time, the rising connecting frame 107g-1 and the connecting rod 107g-2 will drive the pressing block 109a to the highest point, and the inclined plate 108b to the lowest point, and finally the dry powder that has not been sprayed out of the first cavity 104 will continue to fall after passing through the second cavity 105, and can fall on the surface of the fireproof cloth 106c again, and finally form a dry powder isolation belt on the ground, further blocking the spread of fire.
[0070] In summary, when the fireproof cloth 106c falls, dry powder can be sprayed on the surface of the fireproof cloth 106c to further improve the fire isolation effect. When the fireproof cloth 106c is completely unfolded, the dry powder that has not been sprayed out of the first cavity 104 will eventually pass through the second cavity 105 and continue to fall, and can fall on the surface of the fireproof cloth 106c again, and finally form a dry powder isolation belt on the ground, which further blocks the spread of fire.
[0071] Example 3
[0072] Reference Figure 1 to Figure 12 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides a fire protection system, including a fire spread prevention frame, and a fire protection system. The fire protection system includes,
[0073] The dry powder fire extinguishing device installed on top of the transformer, and the overall process of the fire extinguishing system.
[0074] Specifically, the overall process of the fire extinguishing system includes:
[0075] S0: Fire spread prevention racks and dry powder fire extinguishing devices are put into operation;
[0076] S1: Monitor the transformer through the temperature, smoke and light sensors installed inside the transformer and transmit the signal to the fire alarm device;
[0077] S2: The fire alarm device determines whether a fire has occurred based on the signals from the temperature, smoke and light sensors. If a fire has occurred, the device will enter S3 to activate the fire alarm and the fire alarm monitoring platform. If no fire has occurred, the device will enter S1.
[0078] S3: After the fire alarm and fire alarm monitoring platform are activated, the staff can manually confirm the fire after receiving the alarm. If a fire occurs, they will enter S5, if not, they will enter S1. After the fire alarm and fire alarm monitoring platform are activated, if there is no manual confirmation, they will directly enter S5 after a delay.
[0079] S4: After hearing the alarm, the staff can manually confirm the fire. If a fire occurs, they will enter S5, and if there is no fire, they will enter S1;
[0080] S5: After receiving manual confirmation or after the fire alarm bell or fire alarm monitoring platform action alarm has no one to confirm the delayed action, this step will be activated, the fire spread prevention frame will be activated, and after the action is completed, it will enter S6 after a delay;
[0081] S6: After the delay of the fire spread prevention frame, this step is to put the dry powder fire extinguishing device into operation and enter S7;
[0082] S7: The process ends.
[0083] Furthermore, fire monitoring is more accurate and safer through S3 manual review and delayed triggering.
[0084] In summary, when a fire occurs in the equipment, it will automatically start to extinguish the fire, which can achieve effective isolation from other adjacent equipment, accelerate fire extinguishing, and control the fire when it is small. By setting up the fire spread prevention rack and the dry powder fire extinguishing device to cooperate with each other, it can prevent the accident from expanding, minimize the damage to the burning equipment and the impact on other equipment. At the same time, the firefighters do not need to hold the fire extinguishing equipment themselves to extinguish the fire, reducing the risk of personal injury caused by participating in the fire fighting.
