The side, close to the optical lens, of the air injection box is an inclined plane, and when the temperature near the monitor rises due to the fire situation of a power station, the trigger switch is turned on to drive the air injection box to reciprocate at the front end of the monitor, so that the air injection box forms air flow at the front end of the monitor to disturb smoke diffusing near the monitor; when the smoke particles are subjected to the acting force of the airflow, the original static distribution or flowing direction of the smoke particles can be changed, so that the smoke particles are not blocked in front of a monitor lens in a dense form any more, the smoke particles are distributed more sparsely, and the blocking of the smoke particles on a monitor picture is reduced; therefore, misjudgment of workers or smoke rescue opportunities can be reduced, and rescue work can be carried out.

Description

Technical Field

[0001] The utility model relates to the technical field of remote fire monitoring, in particular to a remote centralized monitoring device for power station fires. Background Art

[0002] In the prior art, a power station usually refers to a facility or business unit that converts some form of raw energy into electrical energy. Specifically, it may refer to a power station or hydroelectric station built on water bodies such as rivers and lakes, which converts water energy into electrical energy to generate powerful electricity;

[0003] Since power stations use a large number of equipment and mechanical facilities to generate electricity, such as generators, boilers, steam turbines, transformers, etc., after long-term use, the power equipment and lines in the power station will malfunction due to insulation aging, short circuit, overload or poor contact. These electrical failures are prone to cause fire accidents. Therefore, it is necessary to install a remote centralized fire monitoring device in the power station to monitor the fire situation of the power station in real time. However, the structure of existing monitoring devices is generally simple. When facing a fire situation, the fire will produce thick fog. This thick fog will drift to the surface of the monitoring device under air circulation, thereby forming image interference on the monitoring device. This interference will cause the monitoring image to be blurred or even completely block important information, making it impossible for staff to accurately judge the actual situation of the fire, affecting the staff's viewing of the monitoring image, and even leading to misjudgment or delaying the rescue opportunity, which is not conducive to the rescue work.

[0004] Therefore, we proposed a remote centralized monitoring device for power station fires to solve the above problems. Utility Model Content

[0005] In view of the deficiencies of the prior art, the present invention provides a remote centralized monitoring device for power station fires, which solves the problems raised in the above-mentioned background technology.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A remote centralized monitoring device for power station fires comprises a monitor, an optical lens is fixedly connected to one side of the monitor, a jet box is fixedly connected to the upper end face of the monitor, the jet box is inclined on the side close to the optical lens, air outlet holes are equidistantly formed on the side close to the optical lens of the jet box, air inlet holes are equidistantly formed on the upper end face of the jet box on the side close to the air outlet holes, and one-way valves are provided in both the air outlet hole and the air inlet hole.

[0008] As a further solution of the utility model: a piston plate is slidably connected in the jet box, a piston rod is fixedly connected to the center of the piston plate away from the air outlet, the piston rod penetrates and is slidably connected to the jet box, the end of the piston rod away from the jet box is fixedly connected to a frame, a linkage column is slidably connected in the frame, a shift rod is fixedly connected to the lower end of the linkage column, a drive shaft is fixedly connected to the end of the shift rod away from the linkage column, and the drive shaft is rotatably connected to the upper end surface of the monitor.

[0009] As a further solution of the utility model: a switch is fixedly connected to the lower end surface of the monitor, and the switch is electrically connected to the drive shaft. Slide grooves are symmetrically opened on the lower end surface of the monitor, and sliders are slidably connected in the slide grooves. A bimorph memory alloy plate is fixedly connected between the lower end surfaces of the sliders, and the bimorph memory alloy plate is located directly below the switch.

[0010] As a further solution of the utility model: the opposite side of the slider is fixedly connected with a spring, and the end of the spring away from the slider is fixedly connected to the inner wall of the slide groove.

[0011] As a further solution of the utility model: the monitor is symmetrically fixedly connected with slide rails on one side close to the optical lens, a lifting frame is vertically slidably connected between the slide rails, and the lifting frame is fixedly connected with a flexible brush on the side close to the optical lens.

[0012] As a further solution of the utility model: both sides of the lifting frame are rotatably connected with connecting rods, and one end of the connecting rod away from the lifting frame is rotatably connected to the side wall of the frame.

[0013] Beneficial effects of the utility model:

[0014] 1. The utility model can monitor the temperature near the monitor in real time by setting a dual-shaped memory alloy plate, and when a fire occurs in the power station and the temperature near the monitor rises, the switch is triggered to open, driving the jet box to reciprocate at the front end of the monitor, so that the jet box forms an airflow at the front end of the monitor, disturbing the smoke diffused near the monitor, and when the smoke particles are affected by the airflow, their original static distribution or flow direction will be changed, so that the smoke particles are no longer blocked in front of the monitor lens in a dense form, making the distribution of smoke particles become sparse, thereby reducing their blocking of the monitor screen, thereby reducing the occurrence of staff misjudgment or smoke rescue timing, so as to facilitate the development of rescue work;

[0015] 2. The utility model is provided with a flexible brush, which can drive the lifting frame to move up and down on the front side of the monitor while making the jet box move back and forth to dissipate the smoke in the event of a fire, so that the flexible brush is always attached to the front lens of the monitor, and the surface of the monitor lens is wiped up and down back and forth, thereby removing the attachments on the surface of the monitor lens, ensuring the cleanliness of the monitor lens, making the monitor screen clearer, so that rescue personnel can more quickly judge the fire, the location of the fire source and the evacuation of personnel, so as to formulate a more effective rescue strategy and improve the rescue efficiency;

[0016] 3. After the fire is extinguished, the utility model can automatically restore its own deformation and separate from the switch through the dual-city memory alloy plate when the temperature is restored. Therefore, after the fire is extinguished, the drive shaft can be automatically temporarily rotated to save energy consumption, and the dual-city memory alloy plate can be returned to the initial position to continue working when the piston occurs later.

DETAILED DESCRIPTION

[0024] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example

[0026] like Figure 1-5 As shown, a remote centralized monitoring device for power station fire includes a monitor 1, an optical lens 5 is fixedly connected to one side of the monitor 1, a jet box 2 is fixedly connected to the upper end face of the monitor 1, the jet box 2 is inclined on the side close to the optical lens 5, air outlet holes 4 are equidistantly provided on the side close to the optical lens 5 of the jet box 2, air inlet holes 3 are equidistantly provided on the upper end face of the jet box 2 close to the air outlet holes 4, and one-way valves are provided in both the air outlet hole 4 and the air inlet hole 3.

[0027] In this embodiment, Figure 2 and Figure 5 As shown, a piston plate 20 is slidably connected in the jet box 2, and a piston rod 14 is fixedly connected at the center of the side of the piston plate 20 away from the air outlet 4. The piston rod 14 penetrates and is slidably connected to the jet box 2, and the end of the piston rod 14 away from the jet box 2 is fixedly connected to the frame 10, and a linkage column 13 is slidably connected in the frame 10, and a lever 12 is fixedly connected to the lower end of the linkage column 13, and the end of the lever 12 away from the linkage column 13 is fixedly connected to the driving shaft 11, and the driving shaft 11 is rotatably connected to the upper end surface of the monitor 1. When the driving shaft 11 rotates, the linkage column 13 can be driven by the lever 12 to slide back and forth in the frame 10, and the frame 10 is driven to move horizontally back and forth above the driving shaft 11, pulling the piston rod 14 and the piston plate 20 to reciprocate in the jet box 2, thereby sucking external air from the air inlet 3 and then spraying it out from the air outlet 4.

[0028] In this embodiment, Figure 2 and Figure 4 As shown, a switch 19 is fixedly connected to the lower end surface of the monitor 1, and the switch 19 is electrically connected to the drive shaft 11. A slide groove 15 is symmetrically opened on the lower end surface of the monitor 1, and a slider 16 is slidably connected in the slide groove 15. A bimorph memory alloy plate 18 is fixedly connected between the lower end surfaces of the slider 16. The bimorph memory alloy plate 18 is located directly below the switch 19. When the bimorph memory alloy plate 18 is deformed by high temperature, it will contact and squeeze the switch 19, thereby opening the drive shaft 11 to work.

[0029] In this embodiment, Figure 4As shown, a spring 17 is fixedly connected to the opposite side of the slider 16, and the end of the spring 17 away from the slider 16 is fixedly connected to the inner wall of the slide groove 15. When the force on the slider 16 disappears, the rebound force of the spring 17 can push the slider 16 to slide to the initial position inside the slide groove 15.

[0030] In this embodiment, Figure 1 As shown, the monitor 1 is symmetrically fixedly connected with a slide rail 6 on one side close to the optical lens 5, a lifting frame 7 is vertically slidably connected between the slide rails 6, and a flexible brush 8 is fixedly connected with the lifting frame 7 on the side close to the optical lens 5. When the lifting frame 7 slides between the two slide rails 6, it can drive the flexible brush 8 to move synchronously, so that the flexible brush 8 is in contact with the surface of the optical lens 5, and the surface of the optical lens 5 is wiped.

[0031] In this embodiment, Figure 1 As shown, both sides of the lifting frame 7 are rotatably connected with connecting rods 9, and the ends of the connecting rods 9 away from the lifting frame 7 are rotatably connected to the side walls of the frame 10. When the frame 10 moves horizontally back and forth, the lifting frame 7 can be pulled to move synchronously through the arranged connecting rods 9.

[0032] The effects achieved by this embodiment are as follows: In the prior art, when facing a fire situation, the fire will generate thick fog, which will drift to the surface of the monitoring device under air circulation, thereby interfering with the image of the monitoring device. This interference will cause the monitoring image to be blurred or even completely block important information, making it impossible for staff to accurately judge the actual situation of the fire, affecting the staff's viewing of the monitoring image, and even leading to misjudgment or delay in rescue opportunities, which is not conducive to the development of rescue work. The temperature near the monitor 1 can be monitored in real time, and the temperature near the monitor 1 can be monitored in real time when a fire occurs in the power station. As the temperature rises, the trigger switch 19 is turned on, driving the jet box 2 to reciprocate at the front end of the monitor 1, so that the jet box 2 forms an airflow at the front end of the monitor 1, disturbing the smoke diffused near the monitor 1. When the smoke particles are affected by the airflow, their original static distribution or flow direction will be changed, so that the smoke particles are no longer blocked in front of the monitor 1 lens in a dense form, and the distribution of the smoke particles becomes sparse, thereby reducing their blocking of the monitor 1 screen, thereby reducing the occurrence of staff misjudgment or smoke rescue timing, so as to facilitate the development of rescue work;

[0033] Secondly, when a fire occurs and the jet box 2 is moved back and forth to dissipate the smoke, the lifting frame 7 can be driven to move back and forth in front of the monitor 1, so that the flexible brush 8 is always in contact with the front lens of the monitor 1, and the lens surface of the monitor 1 is wiped back and forth up and down, thereby removing the attachments on the lens surface of the monitor 1, ensuring the cleanliness of the monitor 1 lens, and making the monitor 1 picture clearer, so that rescue personnel can more quickly judge the fire, the location of the fire source and the evacuation of personnel, so as to formulate a more effective rescue strategy and improve the rescue efficiency.

[0034] The working process and principle involved in the overall content of the above embodiment are as follows:

[0035] It should be noted that two-way memory effect alloy (also known as two-phase alloy or dual shape memory alloy) is a class of alloy materials with special shape memory effect, which can realize two different shapes at different temperatures. The most common two-way memory effect alloy is nickel titanium alloy (Ni-T i alloy), also known as "Nitinol" alloy or "superelastic alloy", which usually has the following two shapes: high temperature phase and low temperature phase. In the high temperature phase, the material is in an elastic shape and can undergo large elastic deformation, while in the low temperature phase, the material will return to the preset initial shape. Specifically, the transformation temperature (two-way transformation temperature) of nickel titanium alloy (Ni-T i alloy) can be adjusted according to the composition and treatment of the alloy. Usually, the high temperature phase transformation temperature ranges from about 40-100°C, and the low temperature phase transformation temperature ranges from about -10 to 30°C. This range can be adjusted according to the needs of specific applications. The shape memory process of the two-way memory effect alloy is reversible, and it can switch between high temperature and low temperature many times and maintain the same memory effect.

[0036] In the process of using the monitor 1 to monitor the power station, if a fire occurs in the power station, high temperature will be generated. The temperature will rise and contact the monitor 1. At this time, before the temperature contacts the monitor 1, it will first contact the dual-component memory alloy plate 18 on the lower end surface of the monitor 1. When the dual-component memory alloy plate 18 is subjected to high temperature, it will automatically deform from the curved state and move to the horizontal state. At the same time, by pushing the sliders 16 connected to the two sides of the dual-component memory alloy plate 18 to slide in the slide groove 15, the slider 16 is pressed against the spring 17. During the horizontal movement of the dual-shaped memory alloy plate 18, the distance between the monitor 1 and the switch 19 connected to the lower end of the monitor 1 is gradually reduced, and the switch 19 is contacted and pressed. When the switch 19 is pressed, the switch 19 is electrically connected to the drive shaft 11, which can drive the drive shaft 11 to automatically rotate on the upper end of the monitor 1, drive the lever 12 connected to the outer surface of the drive shaft 11 to move synchronously around the drive shaft 11, and drive the linkage column 13 on the upper end of the lever 12 to rotate with the drive shaft 11. The center of the circle rotates synchronously. When the linkage column 13 moves, it will slide back and forth in the frame 10, and the upper end surface of the frame 10 on the driving shaft 11 will be moved back and forth, and the piston rod 14 connected to the side wall of the frame 10 will be pulled to slide back and forth in the jet box 2, and the piston plate 20 connected to the side of the piston rod 14 close to the jet box 2 will be synchronously reciprocated inside the jet box 2. When the piston plate 20 moves away from the air outlet 4, the air outside the jet box 2 can be sucked into the interior through the air inlet 3 for storage. When the piston plate 20 moves close to the air outlet 4, the air stored in the jet box 2 will be ejected from the air outlet 4, and the smoke diffused near the monitor 1 will be disturbed. When the smoke particles are subjected to the force of the airflow, their original static distribution or flow direction will be changed, so that the smoke particles are no longer blocked in front of the monitor 1 lens in a dense form, and the distribution of the smoke particles becomes sparse, thereby reducing their blocking of the monitor 1 screen, thereby reducing the occurrence of staff misjudgment or smoke rescue timing, so as to facilitate the development of rescue work;

[0037] When the driving shaft 11 drives the frame 10 to move back and forth through the lever 12 and the linkage column 13, the frame 10 will synchronously drive one end of the connecting rod 9 connected to the two sides to move back and forth horizontally, so that the connecting rod 9 can reciprocate between an inclined state and a state close to the horizontal state. As the state of the connecting rod 9 changes, the lifting frame 7 connected to the side of the connecting rod 9 away from the frame 10 can be pulled to slide back and forth between the two slide rails 6, thereby driving the flexible brush 8 connected to the side of the lifting frame 7 close to the monitor 1 to reciprocate and wipe the surface of the optical lens 5, thereby removing the attachments on the surface of the monitor 1 lens, ensuring the cleanliness of the monitor 1 lens, and making the monitor 1 picture clearer, so that rescue personnel can more quickly judge the fire, the location of the fire source and the evacuation of personnel, so as to formulate a more effective rescue strategy and improve the rescue efficiency.

[0038] After the fire is extinguished, as the temperature near the monitor 1 drops, the temperature of the dual-component memory alloy plate 18 will continue to drop. When the temperature of the dual-component memory alloy plate 18 drops to the zero point, it will be subject to the rebound force of the spring 17, pushing the slider 16 to slide to the initial position in the slide groove 15, squeezing the dual-component memory alloy plate 18, so that the dual-component memory alloy plate 18 becomes bent again and separates from the switch 19. Therefore, after the fire is extinguished, the rotation of the drive shaft 11 can be automatically stopped to save energy consumption, and the dual-component memory alloy plate 18 can also be returned to the initial position so that it can continue to work when the piston occurs later.
