Example 1:

Please refer to Fig. 1, a heat-regulating box-type substation, including a substation body 1, a plurality of uniformly distributed main cooling vents 2 are dug on the front and rear tops of the substation body 1, and auxiliary cooling vents are dug on the left and right sides of the substation body 1, The inner wall of the auxiliary heat dissipation port is clamped with an expansion heat dissipation plate 3 , and the lower end of the expansion heat dissipation plate 3 is provided with an expansion aid column 4 , which is fixedly embedded on the substation body 1 .

Please refer to Fig. 2-3, the expansion cooling plate 3 includes an outer fixed frame 31 and a self-collapsing mask 32 located in the outer fixed frame 31, the self-collapsing mask 32 has a porous structure, and the self-collapsing mask 32 is made of a flexible material As shown in Figure 4, the self-collapsing mask 32 is fixedly connected with a plurality of evenly distributed The limit cross bar 33, the middle part of the limit cross bar 33 is fixedly connected with a plurality of limit rings 34, the upper end of the auxiliary expansion column 4 moves through the outer frame 31 and matches with a plurality of limit rings 34, through the electric push rod 6. When driving the exposed rod 41 to move down, the limit ring 34 fixed to the exposed rod 41 first drives the limit cross bar 33 to slide down, so that it starts from the upper end of the collapsed mask 32, moves down, and gradually stacks at the bottom, so that the auxiliary heat dissipation port Gradually opened, compared with the shielding of the self-collapsing cover 32, its area for gas overflow is larger, so that hot air can escape faster, effectively avoiding heat accumulation in the substation body 1, and reducing potential safety hazards.

Please refer to Fig. 5 , the expansion-assisting column 4 includes an outer display frame 43 fixedly embedded in the side wall of the substation body 1, an inner sealing rod 42 with an interference fit with the upper end of the outer display frame 43, and an exposed upper end fixedly connected to the upper end of the inner sealing rod 42. Rod 41, the exposed rod 41 moves through multiple limit rings 34 from bottom to top and is fixed with the top limit ring 34, and an electric push rod is fixedly installed between the inner bottom of the outer display frame 43 and the lower end of the inner sealing rod 42 6. The outer end of the expansion-assisting column 4 is connected with a color developing ball 5, which is located below the inner sealing rod 42, and the space surrounded by the lower end of the inner sealing rod 42, the color developing ball 5 and the outer display frame 43 is filled with a color developing ball 5. For the color liquid, the outer frame 43 is an opaque color.

There is a temperature sensor in the substation body 1, and the temperature sensor and the electric push rod 6 are connected to the control center signal in the substation body 1. When the temperature sensor detects that the temperature in the substation body 1 is relatively high, the temperature is lower than that of the substation body. 1. The limit of the safe operating temperature. In actual implementation, the temperature can be controlled to be 10-25°C lower than the limit safe operating temperature. The temperature sensor feeds back the signal to the control center to control the shortening of the hollow control electric push rod 6 and drive the exposed rod 41 Moving downwards, the self-collapsing mask 32 is gradually folded and collapsed downwards as a whole, and then the auxiliary cooling vents are exposed and opened, so that the diameter for air overflow is greatly increased. At this time, with the original cooling fan, the internal hot air More enough to overflow faster and improve the heat dissipation effect.

The inner diameter of the upper end of the outer display frame 43 is small and the inner diameter of the lower end is large, and the longitudinal span of the small part of the inner diameter is not less than 1/3 of the length of the outer display frame 43, so that the inner sealing rod 42 has enough space to move.

In addition, during specific implementation, when the self-collapsing mask 32 is completely collapsed and folded, the upper end of the inner sealing rod 42 is still not completely separated from the small diameter of the outer display frame 43, effectively ensuring the reset of the inner sealing rod 42, and effectively Ensure that the internal chromogenic solution is not easy to overflow.

The chromogenic sphere 5 includes an outer limit hemisphere 51 fixedly connected to the outer end of the outer display frame 43 and an inner dynamic layer 52 located in the outer limit hemisphere 51.

The inner dynamic layer 52 is made of elastic material, and the color liquid is a high-brightness color, so that the inner dynamic layer 52 is attached to the outer limit hemisphere 51 When the inner wall is closed, the color presented is more conspicuous, which is convenient for the staff to detect in time.

In addition, during the specific implementation, the technicians made multiple adjustments so that when the self-collapsing mask 32 is completely collapsed and folded, the chromogenic solution enters the internal dynamic layer 52, so that the surface after expansion is more than 80% just in line with the The inner wall of the outer limit hemisphere 51 is pressed into contact.

When not overheated, the electric push rod 6 does not control the downward movement of the inner sealing rod 42, and the chromogenic liquid squeezes the inner dynamic layer 52 limitedly, and its natural sagging does not contact the inner wall of the outer limit hemisphere 51, or only partially contacts the outer limit hemisphere 51 Contact, so that the color observed at the outer limit hemisphere 51 is not high, and through the change of color difference before and after overheating, the early warning to the staff is realized.

Through the cooperative arrangement of the expansion cooling plate 3 and the auxiliary expansion column 4, when the temperature is overheated, as shown in Figure 9, the expansion cooling plate 3 can be automatically controlled to collapse and fold downwards, and then the auxiliary cooling opening is opened. Compared with the prior art, Furthermore, the area of the internal hot air overflowing is greatly increased, the heat dissipation effect is greatly increased, the accumulation of heat is effectively reduced, and the temperature rise rate in the substation body 1 is suppressed after a long time of work. During the downward collapse and folding process, the color-developing liquid in the expansion-assisting column 4 is squeezed, so that the inner layer of the color-developing ball 5 is extruded and attached to the outer layer, and then the color-developing ball 5 can be visually observed in the outside world The obvious color phenomenon occurs on the surface, and then it can play a certain role in early warning and reminder for the staff, so that they can carry out manual intervention in time and reduce potential safety hazards.

Example 2:

At this time, under the action of buoyancy, it gradually floats back into the outer display frame 43, and the chromogenic ball 5 is re-displayed. Reverted to colorless.

Here is the biggest difference between this embodiment and Embodiment 1, and the rest are consistent with Embodiment 1.

Please refer to Fig. 8, the lower end of the floating ball 9 is fixedly embedded with a magnetic piece 91, the floating ball 9 is a hollow structure, and the floating ball 9 is filled with air. The overall gravity is small, and the buoyancy in the chromogenic liquid is relatively large, so that the buoyancy is concentrated and distributed at the bottom of the inner sealing rod 42, so that it is not easy to observe the color at the chromogenic sphere 5 without overheating, and the inner wall of the outer limit hemisphere 51 is fixed and inlaid There are a plurality of magnetic points, and the magnetic points and the magnetic sheet 91 are matched with each other. When overheating, the electric push rod 6 controls the inner sealing rod 42 to move down, and it squeezes a plurality of floating balls 9 to move down, so that it enters the color developing ball 5, at the same time, the chromogenic liquid extrudes the inner dynamic layer 52 to make it expand, making it attached to the inner wall of the outer limit hemisphere 51. At this time, the magnetic points on the outer limit hemisphere 51 and the magnetic sheet 91 are mutually adsorbed, under the influence of buoyancy and magnetic attraction Under the joint action, the floating ball 9 is attached to the inner wall of the chromogenic ball 5 and distributed. At this time, the colored phenomenon on the chromogenic sphere 5 can be clearly observed from the outside. Ball 5 changes from colorless to colored, the contrast is more obvious, and the reminder and early warning effect to the staff is better.

The two implementation modes can be selected by technicians according to needs during specific implementation.
