Description

Technical Field

[0001] This invention relates to the field of substation accessory technology, and more specifically, to a heat dissipation device for an energy-saving outdoor prefabricated substation. Background Technology

[0002] Traditional prefabricated substations are mainly classified into American-style and European-style prefabricated substations based on their structure. The various equipment within a prefabricated substation varies in height and is often arranged in a triangular or U-shaped planar layout. From a technical perspective, the main disadvantage of prefabricated substations is poor heat dissipation.

However, in actual use, the operation of the fans also requires electricity. Prefabricated substations are generally installed on a foundation pit, and the bottom of the foundation pit is in a low-temperature state for a long time. How can we utilize the low temperature at the bottom of the foundation pit to dissipate heat from the prefabricated substation and better achieve the effect of an energy-saving outdoor prefabricated substation?

The motor body and the speed reducer are disposed inside an air extraction cylinder and located on one side of an inner shaft. The motor body is connected to the inner shaft via the speed reducer.

[0011] According to an embodiment of the present invention, the heat dissipation device of the energy-saving outdoor box-type substation has a supporting outer wall at the upper end of the foundation pit, and the supporting outer wall is 300-500mm above the outdoor ground level.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0035] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0036] like Figures 1-3 As shown, the present invention provides a heat dissipation device for an energy-saving outdoor prefabricated substation, comprising: a heat dissipation device body 100, the heat dissipation device body 100 including a foundation pit 1, an operating platform 2 installed on the foundation pit 1, and an energy-saving outdoor prefabricated substation 200 installed on the operating platform 2. A first through hole 21 is provided on the operating platform 2, and a second through hole 201 is provided at the bottom of the energy-saving outdoor prefabricated substation 200, the second through hole 201 corresponding to the first through hole 21. Furthermore, a third through hole 202 is provided at the top of the energy-saving outdoor prefabricated substation 200. Since the foundation pit 1 is located at the outdoor ground level, the foundation pit 1 will be in a low temperature environment for a long time. The temperature difference between the foundation pit 1 and the interior of the energy-saving outdoor prefabricated substation 200 causes air heat convection, which discharges high-temperature hot air through the third through hole 202 at the top of the energy-saving outdoor prefabricated substation 200, thereby achieving a non-powered energy-saving heat dissipation effect under normal conditions, and better achieving the effect of an energy-saving outdoor prefabricated substation.

[0037] Exemplary air extraction mechanism

[0038] Furthermore, in some embodiments of the present invention, an air extraction mechanism 3 is installed on the third through hole 202. Here, the air heat convection caused by the temperature difference between the aforementioned pit 1 and the energy-saving outdoor box-type substation 200 causes the air heat convection to activate the air extraction mechanism 3 through the third through hole 202, thereby allowing the air extraction mechanism 3 to rotate and extract the air inside the energy-saving outdoor box-type substation 200. Thus, the high-temperature hot air inside is discharged. Moreover, the air extraction mechanism 3 can also rotate under the action of external wind force, forming a double left and right rotation with the aforementioned air heat convection, thereby more effectively and efficiently extracting the high-temperature hot air inside the energy-saving outdoor box-type substation 200.

[0039] Furthermore, the aforementioned air extraction mechanism 3 includes an air extraction cylinder 31, on which multiple air vents 311 are provided. A vertical shaft 32 is installed at the top of the air extraction cylinder 31, and a first blade 321 is provided on the vertical shaft 32. A protective cap 320 is also installed on the air extraction cylinder 31, with the first blade 321 located inside the protective cap 320. The protective cap 320 has an air inlet. Further, an inner shaft 33 is also installed inside the air extraction cylinder 31, mounted at the lower end of the vertical shaft 32. The second blade 331 is installed on the shaft 33, so the heat convection of the air inside the energy-saving outdoor box-type substation 200 is discharged to the outside through the vent 311 on the exhaust pipe 31. The external wind also drives the first blade 321 to rotate, which in turn drives the inner shaft 33 to rotate. This causes the second blade 331 on the inner shaft 33 to rotate at the same time, which further enables the high-temperature hot air inside to be discharged to the outside through multiple vents 311, thereby achieving the energy-saving heat dissipation effect without power under normal conditions.

[0040] Exemplary power mechanism

[0041] Furthermore, when the temperature difference is too small and the air convection inside the energy-saving outdoor box-type substation 200 is insufficient to drive the air extraction mechanism 3 to rotate, in some embodiments of the present invention, a power mechanism 34 is also installed inside the air extraction cylinder 31. Here, the power mechanism 34 is connected to the inner shaft 33 for transmission, and the energy-saving outdoor box-type substation 200 supplies power to the power mechanism 34, which in turn drives the air extraction mechanism 3 to rotate, thereby achieving the above-mentioned extraction of high-temperature hot air from inside the energy-saving outdoor box-type substation 200.

[0042] Specifically, the aforementioned power mechanism 34 includes a motor body 341 and a reduction gear 342. Here, the motor body 341 and the reduction gear 342 are installed inside the air extraction cylinder 31 and located on one side of the inner shaft 33. The motor body 341 is connected to the inner shaft 33 through the reduction gear 342, which enables the rotation of the inner shaft 33, thereby driving the second blade 331 on the inner shaft 33 to rotate, accelerating the extraction of high-temperature hot air from the energy-saving outdoor box-type substation 200 through multiple vents 311.

[0043] Furthermore, a supporting outer wall 11 is installed at the upper end of the foundation pit 1. The supporting outer wall 11 is 300-500mm higher than the outdoor ground level W. Specifically, it can be 400mm higher than the outdoor ground level W. This supports the operating platform 2. Multiple electric windows 12 are installed on the supporting outer wall 11. These electric windows 12 are electric louvers, which can be easily opened to allow outside air to enter the foundation pit 1 and form low-temperature air in the foundation pit 1.

[0044] like Figure 4 As shown, an exhaust fan 203 is installed on the side wall of the energy-saving outdoor box-type substation 200. When the temperature difference is too small to drive the exhaust mechanism 3 to rotate, the exhaust fan 203 can be activated to extract the high-temperature hot air inside the energy-saving outdoor box-type substation 200 to the outside. It can be understood that the exhaust fan 203 is an electric exhaust fan. A corresponding temperature sensor (not shown) is also installed inside the energy-saving outdoor box-type substation 200 to better cooperate with the exhaust fan 203.

[0045] Exemplary internal support module

[0046] like Figures 5-13 As shown, in some embodiments of the present invention, an internal support module 4 is further configured in the foundation pit 1. The internal support module 4 can be located in the middle of the foundation pit 1. Specifically, the internal support module 4 includes a vertical column 41, a reinforcing base 42, and a settling-preventing part 43. The settling-preventing part 43 is installed in the inner pit 13 of the foundation pit 1, while the reinforcing base 42 is installed on the upper part of the settling-preventing part 43. The vertical column 41 is installed on the reinforcing base 42, and the upper end of the vertical column 41 abuts against the operating platform 2 through the inner pad 40. The internal support module 4 supports the operating platform 2 in the foundation pit 1. The settling-preventing part 43 can play a good role in resisting settlement, thereby increasing the strength of the operating platform 2 and preventing the middle part of the operating platform 2 from settling and collapsing.

[0047] Exemplary sedimentation barrier

[0048] like Figures 7-9As shown, in some embodiments of the present invention, the aforementioned anti-settling part 43 includes an inner column 44, an anti-settling cylinder 45, an outer linkage member 46, and an inner reinforcing claw member 47. Here, the anti-settling cylinder 45 is installed in the inner pit 13, and the inner column 44 is installed on the anti-settling cylinder 45. The vertical column 41 is installed on the inner column 44, the outer linkage member 46 is movably installed on the inner column 44, and the inner reinforcing claw member 47 is inside the anti-settling cylinder 45. The outer linkage member 46 and the inner reinforcing claw member 47 are movably connected. After the above structure is installed, the operator can use external instruments, such as a hydraulic mechanism (not shown), for external linkage. When component 46 moves, the outer linkage component 46 moves towards the inner column 44. At the same time, the outer linkage component 46 also drives the inner reinforcing claw component 47 to move, so that the inner reinforcing claw component 47 can extend into the inner pit 13 from the anti-sinking cylinder 45, thereby increasing the installation stability of the anti-sinking cylinder 45 and the bottom of the inner pit 13. When the outer linkage component 46 approaches the inner column 44, it can be poured. After solidification, a reinforcing base 42 is formed. Then the hydraulic mechanism can be unloaded and removed. The outer linkage component 46, the inner reinforcing claw component 47 and other components are fixed by the reinforcing base 42. In this way, the anti-sinking part 43 can firmly provide internal support for the operating platform 2.

[0049] Exemplary external linkage component

[0050] like Figures 9-10 As shown, further, some embodiments of the present invention provide a specific structure of the external linkage member 46. Here, multiple external linkage members 46 can be provided and evenly distributed around the inner column 44, so that multiple external linkage members 46 can uniformly move the inner reinforcing claw member 47, making the movement of the inner reinforcing claw member 47 more consistent.

[0051] Specifically, the external linkage component 46 of this structure includes a vertical external linkage seat 461 and a side V-shaped hinge rod 462. Correspondingly, multiple vertical sliding grooves 441 are formed on the outer wall of the inner column 44. The upper and lower ends of the side V-shaped hinge rod 462 are respectively connected to the slider 442 in the vertical sliding groove 441, and the slider 442 is connected to the first spring 443. The middle end of the side V-shaped hinge rod 462 is connected to the inner hinge seat 463 on the vertical external linkage seat 461. Therefore, the hydraulic mechanism (not shown) controls the vertical external linkage seat. When 461 is activated, it moves towards the inner column 44, and then the side V-shaped hinge 462 is inside the vertical outer coupling 461, making the movement of the vertical outer coupling 461 more stable. At the same time, the vertical outer coupling 461 is movably connected to the inner reinforcing claw 47, which also drives the movement of the inner reinforcing claw 47 in the anti-settlement cylinder 45, so as to further fix the inner reinforcing claw 47 into the inner pit 13, increasing the contact area of ​​the anti-settlement cylinder 45 in the inner pit 13, so as to play the role of inhibiting settlement.

[0052] Exemplary internally reinforced claw

[0053] Furthermore, some embodiments of the present invention provide a specific structure for the aforementioned internally reinforcing claw 47. This internally reinforcing claw 47 includes an internal lifting seat 471, a guide seat 472, multiple transverse guide rods 473, and multiple vertical claw rods 474. The internal lifting seat 471 is slidably installed inside the sediment trapping cylinder 45. Multiple transverse guide rods 473 pass through the upper guide holes 452 of the sediment trapping cylinder 45. The outer ends of the transverse guide rods 473 are connected to the external linkage member 46. The guide seat 472 is installed above the internal lifting seat 471, and multiple vertical claw rods 474 are installed below the internal lifting seat 471. Correspondingly, a lower guide hole (not shown) corresponding to the vertical claw rods 474 is provided at the bottom of the sediment trapping cylinder 45. Therefore, when the external linkage member 46 moves onto the transverse guide rods 473, the transverse guide rods 473 may have an internal top spring 4731. Through the internal top spring 473... 731 can increase the movement stability of the vertical outer coupling seat 461. When the inner top spring 4731 is contracted to the maximum extent, it drives the horizontal guide rod 473 to move towards the guide seat 472. Here, the guide seat 472 has multiple inclined guide surfaces 4721. Then, the top head 4732 at the inner end of the horizontal guide rod 473 acts on the inclined guide surface, so the horizontal movement is converted into vertical movement. Then, the inner lifting seat 471 moves downward. The multiple vertical claw rods 474 below pass through the lower guide hole (not shown) and enter the inner pit 13. The lower end of the vertical claw rod 474 has a pointed head 475. The pointed head 475 makes it easier to enter the inner pit 13, increasing the stability of the anti-sinking cylinder 45 in the inner pit 13. At the same time, a second spring 451 is installed in the anti-sinking cylinder 45. The second spring 451 abuts against the inner lifting seat 471, so the downward movement of the inner lifting seat 471 is also more stable.

[0054] Exemplary internally reinforced claw

[0055] like Figures 11-13As shown, further, in some embodiments of the present invention, the internally reinforced claw 47 also includes a transverse inner claw 48, wherein a side guide hole 453 is provided on the anti-sinking cylinder 45, and the transverse inner claw 48 includes a lower pressing block 481, a transverse claw cylinder 482, a transverse claw body 483, and a plurality of circumferential claw bodies 484, wherein the lower pressing block 481 is installed on the vertical claw rod 474, the transverse claw cylinder 482 can be inserted into the side guide hole 453, the transverse claw body 483 is movably installed on the outer end of the transverse claw cylinder 482, and the plurality of circumferential claw bodies 484 are movably installed in the circumferential guide hole 485 of the transverse claw cylinder 482, and the transverse claw body 483 is movably connected to the plurality of circumferential claw bodies 484, so when the upper When the vertical claw rod 474 moves downward, the lower pressure block 481 acts on the transverse claw cylinder 482, causing the transverse claw cylinder 482 to pass through the side guide hole 453 and enter the side of the inner pit 13. At the same time, when the transverse claw body 483 on the transverse claw cylinder 482 enters the side of the inner pit 13, the inner pit 13 also exerts a reverse effect on the transverse claw body 483. As a result, the transverse claw body 483 retracts into the transverse claw cylinder 482 and acts on multiple circumferential claw bodies 484. The multiple circumferential claw bodies 484 then pass through the circumferential guide hole 485 and extend into the side of the inner pit 13, thereby increasing the contact area of ​​the sedimentation-resistant cylinder 45 in the inner pit 13 to play the role of inhibiting sedimentation.

[0056] Exemplary lateral claw barrel

[0057] Furthermore, in some embodiments of the present invention, a third spring 486 and an inner baffle 487 are installed inside the transverse claw cylinder 482, and the transverse claw body 483 passes through the third spring 486 and the inner baffle 487. The inner end of the transverse claw body 483 has a first guide block 488, and the inner end of the circumferential claw body 484 has a second guide block 489 corresponding to the first guide block 488. The circumferential claw body 484 has a fourth spring 490, which abuts against the second guide block 489 and the inner wall of the transverse claw cylinder 482. Therefore, when the transverse claw body 483 moves into the transverse claw cylinder 482, the first guide block 488 acts on multiple second guide blocks 489, and then the second guide blocks 489 drive the circumferential claw body 484 to extend outward into the side of the inner pit 13, thereby increasing the contact area of ​​the anti-settlement cylinder 45 in the inner pit 13, so as to play the function of inhibiting settlement.

[0058] The third spring 486 is used to keep the transverse claw body 483 extended from the transverse claw cylinder 482 before entering the inner pit 13; the fourth spring 490 is used to keep the circumferential claw body 484 retracted inside the transverse claw cylinder 482 before entering the inner pit 13.
