Description

Technical Field

[0001] The utility model belongs to the technical field related to electric power devices, and specifically relates to a temperature control component for an outdoor box-type transformer substation. Background Art

[0002] In traditional box-type substations, the heat generated by the internal equipment during operation accumulates, causing the temperature inside the box to be too high. If the heat is not dissipated in a timely and effective manner, it may cause the equipment to overheat, reduce performance, or even be damaged, thus affecting the overall operational stability of the substation. Most current heat dissipation methods rely on forced air cooling or natural ventilation, but such methods are difficult to achieve precise temperature regulation, especially when the temperature changes greatly or the external environment is complex. It is difficult to ensure that the temperature inside the box is always within an appropriate range. In addition, conventional ventilation structures often have poor sealing problems, which makes it easy for dust and moisture outside the box to enter, further exacerbating equipment losses and failure rates.

[0003] Most of the temperature control solutions in the prior art can only achieve simple switch adjustment, and it is difficult to accurately control the dynamic changes in the temperature inside the box. When the temperature changes greatly, the opening and closing of the ventilation device is not flexible enough, and it cannot well cope with the different degrees of heat dissipation requirements, which easily leads to drastic temperature fluctuations inside the box. At the same time, the existing temperature control device usually lacks an automatic reset mechanism when disturbed by external forces, which easily causes damage to the ventilation structure and shortens its service life.

[0004] Therefore, how to achieve more intelligent, precise and stable temperature control while ensuring the sealing of the box-type substation has become a technical problem that needs to be solved urgently.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0009] Several double-opening components;

[0010] A number of double-opening components are rotatably arranged on opposite sides of two vertical beams for on-off control of airflow;

[0014] The temperature difference responder is fixedly connected to one side of the corresponding vertical beam, and the temperature difference responder is used to control the opening and closing amplitude of the double-opening component according to temperature changes;

[0015] Two collaborative components;

[0016] The two cooperative components are symmetrically arranged on both sides of the double-opening component, and the cooperative component is fixedly connected to one end of several double-opening components.

[0018] The temperature difference responder also includes a temperature difference bag which penetrates and is fixed on one side of the vertical beam, and a plurality of heat conducting sheets are evenly arranged on one side of the temperature difference bag.

[0019] As a further solution of the utility model: the sealing plate includes a sealing body, a sealing strip which fits and seals the sealing body is arranged on one side of the sealing body close to the double-opening component, and convex edges are arranged on both sides of the sealing body.

[0020] As a further solution of the utility model: a connecting pipe is provided between the temperature difference package and the telescopic rod for connecting and flowing the medium therebetween.

[0021] As a further solution of the utility model: the double-opening assembly comprises an outer blade and an inner blade, the inner blade is slidably arranged on the inner wall of the outer blade, and a connecting block is fixed to one end of the outer blade away from the inner blade;

[0022] A sealing strip for sealing is arranged on one side of the outer blade.

[0024] As a further solution of the utility model: the inner wall of the vertical beam is symmetrically provided with two slots, and a plurality of sealing plates on the same side are vertically stacked and slide on the inner walls of the two slots.

At the same time, the design of the double-opening component enables the device to automatically reset when subjected to external force, further improving the durability and stability of the system and ensuring the long-term and efficient operation of the device.

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0041] like Figures 1 to 9 As shown, an outdoor box-type substation temperature control component includes:

[0042] The frame structure is formed by fixing the adjacent ends of two horizontal beams 1 and two vertical beams 2 in pairs;

[0043] Several double opening components 5;

[0044] A plurality of double-opening components 5 are rotatably arranged on opposite sides of the two vertical beams 2 for on-off control of the airflow;

[0045] Several sealing plates 3;

[0046] The sealing plate 3 is arranged to fit the inner wall of the corresponding frame structure, and the sealing plate 3 fits the end edge of the corresponding double-opening component 5 to improve the sealing performance;

[0047] Two temperature difference responders 4;

[0048] The temperature difference responder 4 is fixedly connected to one side of the corresponding vertical beam 2, and the temperature difference responder 4 is used to control the opening and closing amplitude of the double-opening component 5 according to temperature changes;

[0049] two collaborative components 6;

[0050] The two cooperative components 6 are symmetrically arranged on both sides of the double-opening component 5, and the cooperative component 6 is fixedly connected to one end of several double-opening components 5. One side of the cooperative component 6 is fixedly connected to one end of the temperature difference responder 4 for synchronous movement of several double-opening components 5.

[0051] Specifically, Fig. 9 As shown, the temperature difference responder 4 includes a fixing frame 41 fixedly connected to one side of the vertical beam 2, a telescopic rod 42 is fixedly connected to the inner wall of the fixing frame 41, the telescopic end of the telescopic rod 42 is movably connected to a transfer block 43 through a pin shaft, the other end of the transfer block 43 is movably connected to a torsion plate 44 through a pin shaft, a rectangular shaft 45 is fixedly passed through one side of the torsion plate 44, a torsion spring 46 is arranged in a coiled shape on the surface of the rectangular shaft 45, and the two ends of the torsion spring 46 are respectively fixedly connected to the opposite surfaces of the vertical beam 2 and the torsion plate 44;

[0052] The temperature difference responder 4 further includes a temperature difference bag 47 penetrating and fixed on one side of the vertical beam 2 , and a plurality of heat conducting sheets 48 are evenly arranged on one side of the temperature difference bag 47 .

[0053] The temperature difference responder 4 is filled with a medium according to the temperature requirements. The expansion of the temperature difference bag 47 drives the telescopic rod 42, which is then twisted by the torsion spring 46, and the rectangular shaft 45 is rotated by the torsion spring 46 as a transfer to achieve deflection transmission.

[0054] Specifically, Figure 7 As shown, the sealing plate 3 includes a sealing body 31 , a sealing strip 33 which fits and seals the sealing body 31 is provided on one side of the sealing body 31 close to the double-opening component 5 , and convex ridges 32 are provided on both sides of the sealing body 31 .

[0055] By providing the seal 33 , the deflection angle of the double-open component 5 can be limited, and at the same time, one end of the double-open component 5 can be fitted together to improve the sealing performance of the closed state.

[0056] The design of the ridge 32 can maintain cooperation with the slot 8 to achieve a position-limited installation setting.

[0057] Specifically, Fig. 9 As shown, a connecting pipe 7 is provided between the temperature difference package 47 and the telescopic rod 42 for communicating the flow of the medium therebetween.

[0058] The connecting pipe 7 is used to transfer the medium flow between the temperature difference package 47 and the telescopic rod 42, so as to avoid leakage of the medium.

[0059] Specifically, Figure 8As shown, the double-opening assembly 5 comprises an outer blade 51 and an inner blade 52, wherein the inner blade 52 is slidably arranged on the inner wall of the outer blade 51, and a connecting block 53 is fixed to one end of the outer blade 51 away from the inner blade 52;

[0060] A sealing strip 54 for sealing is provided on one side of the outer blade 51 .

[0061] The connecting block 53 is used to connect the outer blades 51 and the inner blades 52 as a transmission relay. At the same time, the sealing strip 54 is located on the inner wall of the outer blades 51, which can cooperate with the inner blades 52 to maintain a close seal, thereby achieving a stable sealing and heat preservation effect in cold seasons.

[0062] Specifically, Figure 7 As shown, the cooperative component 6 includes a core disk 61 fixedly connected to the surface of the rectangular shaft 45, and the surface of the core disk 61 is movably connected to two synchronization bars 62 through a pin shaft, and the other end of the synchronization bar 62 is movably connected to a synchronization disk 63 through a pin shaft.

[0063] By adopting the cooperative component 6, the core disk 61 of the cooperative component 6 can be rotated synchronously with the torsion disk 44 of the temperature difference responder 4. The core disk 61 can deflect with the two synchronous disks 63 under the action of the synchronization bar 62 to maintain the coordination of the rotation angle.

[0064] Specifically, Figure 6 As shown, two slots 8 are symmetrically formed on the inner wall of the vertical beam 2 , and a plurality of sealing plates 3 on the same side are vertically stacked and slid on the inner walls of the two slots 8 .

[0065] The card slot 8 is opened on the inner wall of the vertical beam 2, which can limit the sealing plate 3 so that the sealing plate 3 can maintain vertical stacking and keep one side closed.

[0066] Specifically, Figure 6 As shown, the core disk 61 and the two synchronous disks 63 are fixedly connected to one end of the double-opening component 5, and the two double-opening components 5 are respectively fixedly connected to one end of the outer blade 51 and the inner blade 52 of the double-opening component 5.

[0067] By separately controlling the outer blades 51 and the inner blades 52 of the double-opening component 5, the cooperative components 6 on both sides thereof can respectively control the synchronous deflection of the three outer blades 51 and the inner blades 52 relative to each other.

[0068] When this solution is used, it is installed at the reserved opening position of the box-type substation, and the temperature difference responder 4 faces the inside. Then, when the temperature inside the box-type substation rises, the two temperature difference responders 4 can deflect with the expansion of the internal medium with the double-open components 5. When the multiple double-open components 5 are deflected, the angles are synchronized through the cooperative component 6, so that there can be gaps in the double-open components 5 in the closed state to achieve air flow. The larger the opening, the faster the heat exchange speed. The temperature inside the box-type substation evaporates and is discharged, and the outside air enters the bottom;

[0069] At the same time, the two temperature difference responders 4 are filled with media with different expansion coefficients. When the temperature difference bag 47 of the temperature difference responder 4 corresponding to the low expansion coefficient is heat-conducted by the heat conducting sheet 48, the internal medium expands, so that it enters the telescopic rod 42 through the connecting pipe 7. The telescopic rod 42 is extended and retracted under the support of the fixing frame 41, and the torsion plate 44 is deflected by the adapter block 43 at the end through the pin shaft. When the torsion plate 44 is deflected at one end of the rectangular shaft 45, the rectangular shaft 45 is deflected by the elastic force of the torsion spring 46. The rectangular shaft 45 rotates with the core disk 61 on the corresponding side. The core disk 61 rotates with the synchronous disk 63 through two synchronous bars 62, so that the core disk 61 and the synchronous disk 63 simultaneously deflect with the connecting block 53 and the inner blades 52. As the deflection of the inner blades 52 increases, the gas flow increases.

[0070] If the inner blades 52 are deflected, the internal temperature continues to rise after the airflow velocity increases, then the medium inside the temperature difference responder 4 on the other side begins to expand to a certain coefficient, and causes the core disk 61 of the cooperative component 6 on this side to deflect, so that the three outer blades 51 begin to deflect synchronously, and the overall passability is increased;

[0071] The above scheme provides two-segment temperature control. Through the action of media with different temperature coefficient changes, heat dissipation control can be achieved, and the opening is more linear, which can keep the internal temperature within a constant range without being too high or causing a sudden drop in temperature. The overall temperature control is linear and well controlled, and the use is stable. When the double-opening component 5 is interfered by external force, the double-opening component 5 is deflected and unloaded through the deformation of the torsion spring 46, and it automatically resets after losing the external force, making it not easy to be damaged as a whole.

[0072] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
