Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of power transmission and transformation engineering, and particularly relates to an automatic temperature control structure suitable for a transformer substation. Background Art
[0002] As urban economies continue to accelerate, demand for electricity is growing. To meet this demand, the number of urban substations is increasing, and substation maintenance is becoming more frequent. Furthermore, the main transformer is one of the devices that generates the most heat within a substation, resulting in high temperatures in the main transformer room during operation. While this high temperature does not affect equipment operation, it can cause discomfort and distress to production, maintenance, and inspection personnel during daily operations.
[0003] At the same time, in the existing technology, the high temperature problem in the main transformer room is generally addressed by installing shutters at the bottom of the removable and explosion-proof main transformer room door, and adding large shutters at the top of the opposite wall to ensure ventilation and heat dissipation in the main transformer room. However, the actual effect is not good. In addition, installing air conditioning in the main transformer room is also unsatisfactory. This is because the main transformer equipment is often quite high (about 6.50 meters), requiring a large cooling space and requiring ventilation and heat exchange year-round. Therefore, using air conditioning for cooling is uneconomical and the effect is not ideal. Summary of the Invention
[0004] In order to solve the problem of excessively high indoor temperature in substations, especially main transformer rooms, and poor traditional cooling effects, the present invention provides an automatic temperature control structure suitable for substations, comprising a temperature measuring device and a substation roof. The temperature measuring device is arranged on the inner wall of the substation and is used to detect the temperature inside the substation.
[0005] A window is provided on the substation roof, and two parallel structural beams are provided at the bottom of the substation roof. A displacement device is provided between the structural beam and the substation roof, and the top of the displacement device is connected to and supports a tempered glass window. The temperature measuring device is electrically connected to the displacement device. When the temperature measuring device detects that the temperature inside the substation exceeds a preset threshold, the temperature measuring device sends the information to the displacement device, and the displacement device drives the tempered glass window to move horizontally and / or vertically on the structural beam, thereby realizing the opening and closing of the window.
[0006] Preferably, the displacement device includes a slide rail and a slider, and the slide rail is arranged above the structural beam along the moving direction of the tempered glass window, and the slider is movably arranged on the slide rail.
[0007] Preferably, the slider is provided with two spiral sliders that move toward each other, and a first strut and a second strut are provided above the slider, and the first strut and the second strut are rotatably connected, and the two ends of the first strut and the second strut are respectively connected to the spiral slider and the bottom of the tempered glass window in a hinged manner. The two spiral sliders move toward each other, driving the first strut and the second strut to rotate, thereby changing the angle between the first strut and the second strut, and then driving the tempered glass window to move up and down.
[0008] Preferably, the slider is provided with two spiral chutes, and each spiral chute is built with a threaded rod, and the thread directions of the two threaded rods are opposite, and a drive motor is provided on one side of each spiral chute, and the output end of the drive motor is connected to the threaded rod;
[0009] The spiral slider is built into the threaded groove and sleeved on the threaded rod, and the threaded rod is threadedly connected to the spiral slider. When the two driving motors synchronously drive the threaded rod to rotate, the threaded rod can drive the two threaded sliders to slide in opposite directions.
[0010] Preferably, the tempered glass window includes a mounting portion and tempered glass, and the mounting portion is a hollow frame structure, and the tempered glass is mounted above the hollow range of the mounting portion, and the tempered glass and the window are opened and closed by a snap-fitting manner.
[0011] Preferably, the tempered glass is convex in the middle and lower than the middle part on all sides, so that when closed, rainwater and dust from the outside will move along the upper surface of the tempered glass to the upper surface of the substation roof and will not stay on the window surface;
[0012] Or / and, the side walls of the tempered glass are in oblique contact with the window.
[0013] Preferably, a sealing rubber pad is provided on the inner wall of the window. When the tempered glass is engaged with the window, the tempered glass will squeeze and fit the sealing rubber pad, thereby achieving the effect of sealing and waterproofing.
[0014] Preferably, it also includes a linkage device and a sprinkler device, and the linkage device is electrically connected to the temperature measuring device, the sprinkler device and the displacement device respectively. When the temperature measuring device detects that the temperature in the substation exceeds a preset threshold, the temperature measuring device sends the information to the linkage device, and the linkage device synchronously transmits the signal to the sprinkler device and the displacement device, thereby achieving sprinkler and window opening at the same time when the temperature is high, and turning off the sprinkler and closing the window after the temperature drops.
[0015] Preferably, the sprinkler device includes a monitor, a control valve, a sprinkler head, a pipeline and an external water supply facility, and the monitor is electrically connected to the linkage device and the control valve respectively. When the linkage device transmits a signal to the monitor, the monitor manipulates the control valve, and by opening the control valve, introduces external water supply from the pipeline, and sprinkles water to cool the substation through the sprinkler head.
[0016] Beneficial effects:
[0017] 1. By setting up a displacement device and a temperature measuring device, the window can be opened and closed according to the temperature. When the indoor temperature exceeds the upper limit threshold set by the temperature measuring device, the displacement device creates a chimney effect by opening the skylight, enhancing indoor air convection, and then maintaining the temperature of the substation (especially the main transformer room) within a more suitable range.
[0018] 2. By setting up a linkage device and a sprinkler system, when the linkage device receives the temperature signal from the temperature measuring device, it transmits the signal to the sprinkler system, which then sprays water to cool the main transformer. The main transformer acts as a heat source, and through water cooling, the indoor temperature can be more efficiently controlled. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0028] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.
[0029] Example 1:
[0030] As attached Figure 1 The external view of the substation of this embodiment is shown, showing a roof 1 with a window 2. Through the window 2, two parallel structural beams 3 and a tempered glass window 5 can be seen. The tempered glass window 5 moves horizontally and / or vertically on the structural beams 3 to open and close the window.
[0031] The tempered glass window 5 includes a mounting portion 52 and a tempered glass 51 . The mounting portion 52 is a hollow frame structure, and the tempered glass 51 is mounted above the hollow area of the mounting portion 52 , with the two being fixedly mounted therebetween.
[0032] At the same time, the tempered glass window 5 and the window 2 are opened and closed by snapping together, and a sealing rubber pad 4 is fixed inside the window 2. When the tempered glass 51 is snapped together with the window 2, the tempered glass 51 will squeeze and fit the sealing rubber pad 4, thereby achieving the effect of sealing and waterproofing.
[0033] Reference Attachment Figure 2 , attached Figure 2 It is attached Figure 1 The internal view of the substation shown. The substation includes a temperature measuring device 7 and a substation roof 1, wherein the temperature measuring device 7 is set on the inner wall of the substation and is used to detect the temperature inside the substation. Figure 1 The structure is as follows: first, a window 2 is opened on the substation roof 1, and two parallel structural beams 3 are set at the bottom of the substation roof, and a displacement device 6 is set between the structural beam 3 and the substation roof 1, and the top of the displacement device 6 is connected to and supports a tempered glass window 5, and the temperature measuring device 7 is electrically connected to the displacement device 6.
[0034] When the temperature measuring device 7 detects that the temperature inside the substation exceeds a preset threshold, the temperature measuring device 7 sends the information to the displacement device 6, and the displacement device 6 drives the tempered glass window 5 to move horizontally and / or vertically on the structural beam 3, thereby opening and closing the window.
[0035] At the same time, the specific structure of the displacement device 6 is shown in the attached Figure 3 and attached Figure 4 As shown: along the moving direction of the tempered glass window 5, a slide rail 61 is fixedly installed above the structural beam 3, and a slider 62 is slidably connected to the surface of the slide rail 61. At the same time, the sliding device between the slider and the slide rail can use existing technology.
[0036] In this embodiment, the slide rail 61 is a linear rolling friction guide rail, and a linear bearing is provided on the slider 62. The steel ball inside the linear bearing rotates with a small friction resistance. According to the signal sent by the temperature measuring device 7, the steel ball slides horizontally on the slide rail 61 by rolling, thereby realizing high-precision and smooth movement of the slider 62 on the slide rail 61.
[0037] Secondly, the specific structure of closing the window is shown in the attached Figure 3 : First, two spiral sliders 622 that move toward each other are provided on the slider 62. At the same time, a first support rod 631 and a second support rod 632 are provided above the slider 62, and the first support rod 631 and the second support rod 631 are rotatably connected, and the two ends of the first support rod 631 and the second support rod 632 are connected to the spiral slider 622 and the bottom of the mounting part 52 in a hinged manner.
[0038] Therefore, when in use, the two spiral sliders 622 move toward each other to drive the first support rod 631 and the second support rod 632 to rotate, thereby changing the angle between the first support rod 631 and the second support rod 632, thereby raising / lowering the mounting portion 52 and driving the tempered glass window 5 to move up and down.
[0039] Furthermore, the tempered glass 51 has a raised center and is lower around its perimeter. This prevents rain and dust from accumulating on the window surface when closed, as they flow along the upper surface of the tempered glass to the upper surface of the substation roof. Furthermore, the sidewalls of the tempered glass 51 form an oblique contact with the window 2, ensuring a more secure fit. Furthermore, the sealing rubber gasket 4 is provided with an oblique contact between the sidewalls of the tempered glass 51 and the sealing rubber gasket 4.
[0040] The specific structure of the spiral sliders 622 in this embodiment to achieve the movement toward each other is shown in the attached Figure 4 : First, the slider 62 is provided with two spiral grooves 621, and each spiral groove 621 has a built-in threaded rod 624, and the thread directions of the two threaded rods 624 are opposite, and a drive motor 623 is provided on one side of each spiral groove 621, and the output end of the drive motor 623 is connected to the threaded rod 624.
[0041] At the same time, the spiral slider 622 is built into the threaded groove 621 and is sleeved on the threaded rod 624, and the threaded rod 624 is threadedly connected to the spiral slider 622. When the two drive motors 623 synchronously drive the threaded rod 624 to rotate, the threaded rod 624 can drive the two threaded sliders 622 to slide in opposite directions.
[0042] Because the threaded slider 622 is hingedly connected to the support rod, the two threaded sliders 622 are driven by the driving motor 623 to slide in opposite directions and approach each other. At this time, the angle between the support rods becomes smaller and the mounting portion 52 is supported. When the two threaded sliders 622 move away from each other under the drive of the driving motor 623, the angle between the support rods becomes larger, thereby lowering the mounting portion 52, thereby realizing the vertical movement of the tempered glass window 5 and the opening and closing of the window 2.
[0043] This embodiment can realize the opening and closing of the skylight with a simple structure. During use, when the temperature of the substation exceeds the upper threshold temperature preset by the temperature measuring device 7 (such as 40°C), the temperature measuring device 7 opens the window 2 on the roof 1 by controlling the displacement device 6, forming a chimney effect to enhance indoor air convection, thereby maintaining the temperature of the substation (especially the main transformer room) within a more suitable range.
[0044] Example 2:
[0045] Reference Attachment Figure 5 Embodiment 2 provides a substation including a temperature measuring device 7 and a displacement device 6, both of which are the same as those in embodiment 1, and further including a linkage device 8 and a sprinkler device 9. The linkage device 8 is electrically connected to the temperature measuring device 7, the sprinkler device 9, and the displacement device 6, respectively. The linkage device 8 is capable of receiving signals from the temperature measuring device, determining whether to open windows and whether to use water cooling, and transmitting relevant instructions to the sprinkler device 9 and the displacement device 6 for execution.
[0046] During operation, when the substation temperature exceeds a preset upper threshold temperature (e.g., 40°C) set by temperature measuring device 7, temperature measuring device 7 controls displacement device 6 via linkage device 8 to open window 2 on substation roof 1. Simultaneously, linkage device 8 transmits a signal to monitor 91 of sprinkler system 9, which then opens a control valve (not shown), introduces external water via a pipe, and sprays the main transformer with water to cool it down via sprinkler heads 92. The main transformer, acting as a heat source, can be rapidly cooled through water cooling and the chimney effect.
[0047] This cooling process typically continues until the substation temperature detected by temperature measuring device 7 is roughly the same as the room temperature outside the substation. At this point, temperature measuring device 7 again transmits a signal to linkage device 8, which controls displacement device 6 to close window 2 on substation roof 1 and controls sprinkler system 9 to close the control valve, effectively stopping watering. Thus, the combined action of temperature measuring device 7, displacement device 6, linkage device 8, and sprinkler system 9 allows for efficient control of the substation's indoor temperature.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
