All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The first embodiment;

referring to fig. 1 to 10, the present invention provides a technical solution: the utility model provides an intelligent modularization switch board, includes switch board body 1, and switch board body 1's lateral wall is fixed with transparent case 2, and the inner wall of transparent case 2 is fixed with horizontal pole 4, and the outer wall slidable mounting of horizontal pole 4 has slider 5, and the inner wall that transparent case 2 is close to slider 5 is fixed with glow stick 3 through the installation knot, and the inside of transparent case 2 is filled with water, and the liquid level of water does not cross glow stick 3.

The inner wall of the transparent box 2 below the cross rod 4 is vertically and slidably provided with the air bag 9 filled with gas, the inner bottom of the transparent box 2 is provided with a locking mechanism used for locking the air bag 9, when the temperature of the power distribution cabinet body 1 rises to a preset value, the locking mechanism releases the locking of the air bag 9, and the air bag 9 floats upwards to enable the sliding block 5 to be close to the fluorescent rod 3 through the transmission assembly and bend the fluorescent rod.

When the power distribution cabinet is used, the power distribution cabinet body 1 can be arranged in a monitoring range, the transparent box 2 is convenient to monitor, and the power distribution cabinet body 1 can be suitable for dark or poor-light environments, such as basements or underground garages.

Switch board body 1 is when normal use, the louvre of seting up can reach radiating purpose on it, make its inside temperature range that keeps at certain safety, when meetting some trouble or other reasons and leading to the untimely overheated phenomenon that causes of heat dissipation, when the temperature in the switch board body 1 risees the default, locking mechanism removes the locking to gasbag 9, this moment under the effect of buoyancy, gasbag 9 can come-up and make slider 5 be close to and bend it to glow stick 3 through making with drive assembly, thereby destroy its inside glass pipe intermediate layer, make inside peroxide and lipid compound carry out the mixing reaction, and make the fluorochrome luminous, send out the warning, thereby can remind overheated phenomenon to appear in staff switch board body 1.

Simultaneously gasbag 9 still can play the effect of rolling to the water in the transparent box 2 when the come-up, makes its liquid level undulant, because transparent box 2 adopts transparent material, so the fluorescence that glow stick 3 sent can see through water and shine transparent box 2 to along with the fluctuation of liquid level, can make the pattern developments of shining rock, both can enlarge and improve the effect of warning, simultaneously can also be convenient for staff's seizure, and then make things convenient for the maintenance personal to look over or maintain the very first time.

Further, the transmission assembly comprises a second connecting rod 7, the second connecting rod 7 is rotatably installed on the outer wall of the cross rod 4 through a pin shaft, a first connecting rod 6 is rotatably connected between one end, close to the fluorescent rod 3, of the second connecting rod 7 and the slider 5, the outer wall, far away from the fluorescent rod 3, of the cross rod 4 is provided with a vertical groove, a vertical rod 8 is slidably installed in the vertical groove, an elongated groove 15 is formed in the outer wall, close to the vertical rod 8, of the second connecting rod 7, a sliding button 16 inserted into the inner wall of the elongated groove 15 is rotatably installed on the outer wall of the vertical rod 8, the sliding button 16 is slidably connected with the inner wall of the elongated groove 15, in an initial state, the sliding button 16 is located below the cross rod 4, and the air bag 9 can be upwards moved to abut against the bottom end of the vertical rod 8.

Known from the foregoing, the airbag 9 floats upwards under the action of buoyancy and then butts against the bottom end of the vertical rod 8, as shown in fig. 4, a thin plate can be installed at the bottom end of the vertical rod 8, the contact area between the thin plate and the airbag 9 is increased, then the vertical rod 8 is pushed by the airbag 9 to slide upwards, the sliding button 16 is in sliding fit with the elongated slot 15, the second connecting rod 7 is driven to rotate along the pin shaft, and the sliding block 5 is driven to move towards the fluorescent rod 3 under the connecting action of the first connecting rod 6, and the fluorescent rod 3 is bent.

Further, the containing box 17 is installed at the interior top of transparent case 2, and the inside of containing box 17 has contained the ammonium nitrate granule, and the bottom that holds box 17 has seted up the blanking mouth, and the interior top that holds box 17 is fixed with empty pipe 18, and the vertical slidable mounting of inner wall of empty pipe 18 has bumping post 20, is connected with spring 19 between bumping post 20 and the interior top of empty pipe 18, and under the initial condition, bumping post 20 will hold the discharge gate of box 17 bottom and seal, and the top area of montant 8 is less than the bottom area of bumping post 20.

When gasbag 9 drives 8 rebound of montant and makes smooth button 16 cross horizontal pole 4, this moment under the connection effect of second connecting rod 7 and first connecting rod 6, slider 5 begins to remove to the direction of keeping away from glow stick 3, simultaneously the top of montant 8 can push up bumping post 20 and upwards slide, and make the compression of spring 19, bumping post 20 withdrawal holds in the case 17 this moment, the discharge gate of bottom is opened, its inside ammonium nitrate granule can fall the aquatic, and take place hydrolysis reaction with water, and this reaction can absorb heat, reduce the temperature in the transparent case 2, utilize heat-conduction to absorb heat to switch board body 1, thereby alleviate the overheated phenomenon of eliminating switch board body 1 even, the time has been prolonged for maintenance person's maintenance, the indirect effect of protection has been played to inside electric power component.

And because the heat absorption can make the temperature shock fall in the transparent case 2, can also restrain the chemical reaction of 3 inside peroxides of fluorescence stick and lipid compound when cooling switch board body 1 to preserve fluorescence stick 3, can also continue to use after the maintenance, prolong its life, reduce the change frequency.

Further, the air bag 9 comprises a non-deformable rigid portion 24 and an elastically extensible elastic extension portion 25, and when the water temperature in the power distribution cabinet body 1 rises to a preset value, the air in the air bag 9 can be heated to expand so as to enable the elastic extension portion 25 to be elastically extended.

As can be known from the foregoing, the airbag 9 drives the vertical rod 8 to move upwards when floating, and due to the reaction force of the fluorescent rod 3 on the slider 5 after being bent to a certain degree, the first connecting rod 6 and the second connecting rod 7 are prevented from rotating, so that the vertical rod 8 is limited from moving upwards, and at the moment, the slide button 16 is still positioned below the transverse rod 4.

And when the luminous warning of glow stick 3, switch board body 1 still is in overheated state, through the heat transfer, can play certain heating effect to the water in the transparent box 2, make the temperature rise, the temperature rise in the gasbag 9 this moment, the inflation of air can make elasticity extension 25 extension, thereby increase the buoyancy that gasbag 9 received, montant 8 can continue rebound this moment, glow stick 3 is continued to be buckled simultaneously, cross horizontal pole 4 until slide button 16, then under the connecting action of first connecting rod 6 and second connecting rod 7, can make slider 5 remove to the direction of keeping away from glow stick 3, cancel the buckling to it, then add the ammonium nitrate in the aquatic.

In conclusion, the air bag 9 can float upwards in two processes, the first process is that an overheating phenomenon just occurs, the light-emitting warning is carried out through the fluorescent rod 3, and the overheating phenomenon can be transient overheating.

The second process is a lasting overheating phenomenon, the water temperature in the transparent box 2 rises, then the sliding button 16 crosses the cross rod 4, the extrusion effect on the fluorescent rod 3 is stopped, ammonium nitrate is added into the water to react and absorb heat, and the power distribution cabinet body 1 is cooled.

Further, locking mechanical system is including rotating two pincers walls 12 of installing the bottom in transparent case 2, and the keeping silent of two pincers walls 12 is relative, the bottom of gasbag 9 is fixed with connecting rod 10, the bottom of connecting rod 10 is fixed with limiting plate 11, it is connected with memory alloy 13 to rotate jointly between two pincers walls 12, memory alloy 13 is heated extensible, memory alloy 13 is connected through heat-conducting wire 14 with the inside device of switch board body 1, and heat-conducting wire 14 all wraps up the insulating layer with memory alloy 13's outer wall, under the initial condition, memory alloy 13 is in the state of shortening, and two pincers walls 12 are closed each other and carry out spacing with limiting plate 11.

Under the normal temperature, memory alloy 13 is in the contraction state, can refer to fig. 4 and fig. 6, and two pincers walls 12 carry on spacingly with limiting plate 11 this moment, and when overheated phenomenon appeared, the heat in the switch board body 1 can transmit for memory alloy 13 through the heat conduction silk, and memory alloy 13 is heated the extension this moment to drive two pincers walls 12 and open, break away from with limiting plate 11, relieve spacing to limiting plate 11, eliminate the spacing to gasbag 9 promptly.

Because the temperature in the switch board body 1 has certain fluctuation, so memory alloy 13 also has the normal flexible volume in certain extent, set up the limiting plate 11 can with two pincers walls 12 between have the fluctuation in certain normal range.

The heat-conducting wires 14 and the outer walls of the memory alloy 13 are wrapped by the heat-insulating layers, so that loss in the heat transfer process can be reduced, and particularly, water in the transparent box 2 is isolated, so that the memory alloy 13 can receive heat more quickly and accurately.

In a second embodiment, a second locking mechanism implementation is provided that differs from the first embodiment.

Further, locking mechanical system is including fixing the iron sheet 22 in gasbag 9 bottom, and the cavity has been seted up to inside that is located transparent case 2 below, and installs electro-magnet 23 in the cavity, and electro-magnet 23 and the interior temperature sensor electric connection of switch board body 1, under the initial condition, electro-magnet 23 and iron sheet 22 magnetic adsorption, when temperature sensor sensed the temperature and rose to the default, can control the demagnetization of cutting off the power supply of electro-magnet 23 through the signal of telecommunication.

The temperature sensor installed in the power distribution cabinet body 1 senses the temperature change of the power distribution cabinet body, when the overheating phenomenon occurs, the temperature sensor can control the electromagnet 23 to cut off the power and demagnetize through an electric signal, the adsorption effect on the iron sheet 22 is cancelled, and therefore the purpose of removing the locking of the air bag 9 is achieved.

Furthermore, an infrared sensor 21 is installed on the inner wall of the transparent box 2 above the water level, and when the infrared sensor 21 detects the vertical rod 8, an external alarm is controlled by an electric signal to give an alarm.

As can be seen from the foregoing, when the vertical rod 8 moves up to contact with the stop pillar 20, which is already in the second process stage, the infrared sensor 21 detects the vertical rod 8 and controls the external alarm to give an alarm through an electric signal, thereby playing a role of further alarming and warning.

Further, let b be the length from the pin joint of the second link 7 to the joint with the first link 6, and let a be the length from the pin joint of the second link 7 to the slide button 16, a > b.

Referring to fig. 8, by setting a > b, although the length of a may change in the process of moving up the vertical rod 8, a labor-saving lever may still be formed between the first connecting rod 6 and the second connecting rod 7, so as to avoid the problem that the second connecting rod 7 cannot be driven to rotate due to too small buoyancy.

Further, the balls are arranged between the vertical grooves formed in the vertical rods 8 and the horizontal rods 4, friction between the horizontal rods 4 and the vertical grooves can be reduced through the balls, and offsetting of buoyancy is reduced.

In summary, when the overheat warning occurs, the warning can be divided into two stages;

the first stage is that overheating occurs just now, the air bag 9 floats upwards after unlocking, the vertical rod 8 is driven to move upwards, the first connecting rod 6 and the second connecting rod 7 are driven to swing through the sliding fit of the sliding button 16 and the long groove 15, the sliding block 5 extrudes the fluorescent rod 3, the fluorescent rod 3 gives out light for warning, and the first sliding button 16 is still located below the transverse rod 4, so that the first layer warning effect is achieved, and meanwhile, the stage can also be suitable for transient overheating.

The second stage is a continuous overheating phenomenon, on the basis of the first stage, the heat in the power distribution cabinet body 1 heats the water in the transparent box 2, so that the water temperature of the water rises, the air pressure in the air bag 9 increases, the elastic extension part 25 can be extended by the expansion of the air, so that the buoyancy force applied to the air bag 9 is increased, at the moment, the vertical rod 8 can continuously move upwards, the fluorescent rod 3 can continuously bend until the sliding button 16 passes through the cross rod 4, then the sliding block 5 can move in the direction away from the fluorescent rod 3 under the connection effect of the first connecting rod 6 and the second connecting rod 7 to cancel the bending of the sliding rod 3, then the ammonium nitrate is added into the water through the matching of the structures, the heat absorption can lead the water temperature in the transparent box 2 to suddenly drop through the chemical reaction of the ammonium nitrate and the chemical reaction of the peroxide and the lipid compounds in the fluorescent rod 3 can be inhibited while the temperature of the power distribution cabinet body 1 is reduced, therefore, the fluorescent rod 3 can be stored and can be continuously used after being maintained, the service life of the fluorescent rod is prolonged, and the replacement frequency is reduced.
