[0004] The components inside the box-type substation will generate high temperatures when working, so cooling fans will be installed in the substation. Box-type substations are generally installed outdoors. When the air outlet direction of the cooling fan is opposite to the wind direction of the external environment, the wind force will affect the dissipation of heat inside the box-type substation, thereby reducing the heat dissipation effect. Summary of the invention

[0005] The present invention provides a prefabricated box-type substation, aiming to solve the technical problem in the related art that the box-type substation is generally installed outdoors.

[0007] When the wind direction is in the positive front-to-back direction and the wind deviates from the left-to-right direction by less than 45 degrees, the heat dissipation modules on the front and rear side walls work, and the heat dissipation fans in the heat dissipation modules are in a state of one working and the other not working. The wind will blow in from the heat dissipation fan on the non-working side, enter the substation body, and blow out from the working heat dissipation fan on the other side, so that a circulation environment is formed inside the substation body, which can better drive the heat dissipation in the substation body. When the wind direction exceeds the range of 90 degrees in the front-to-back direction, the two heat dissipation fans of the heat dissipation modules on the front and rear side walls are in a state of not working. At this time, the wind will pass through the heat dissipation modules set in the left and right directions, and the heat dissipation modules in the left and right directions will start working. The heat dissipation modules in the front-to-back direction and the heat dissipation modules in the left and right directions can work alternately and can adapt to the wind blowing from all directions around the substation body.

[0009] Preferably, bevel gears are provided on both the transmission rod and the driving rod, and the two are meshingly connected.

[0010] The transmission rod can drive the driving rod to rotate, thereby driving the cooling fan to work.

[0011] Preferably, the transmission rod and the driving rod have the same diameter.

[0012] It is convenient for the inner cylinder to pass through the transmission rod, thereby driving the transmission rod to rotate through the matching block.

[0013] Preferably, the surface of the matching block facing the inner cylinder is an inclined surface.

[0016] Preferably, a movable frame is horizontally slidably installed on the substation body at positions corresponding to the cooling fan, and a plurality of filters are vertically arranged on the movable frame. The filter is located on the air outlet side of the cooling fan. One end of the filter is rotatably matched with the substation body, and the other end is provided with a rotating column which vertically slides with the movable frame. It also includes a transmission assembly for driving the movable frame to slide.

[0017] The air needs to be filtered through the filter when entering the non-working cooling fan, but does not need to be filtered through the filter when being discharged from the working cooling fan, thereby being able to bring out the internal dust.

[0018] Preferably, the transmission assembly includes a lifting cylinder slidably fitted on the outside of the rotating rod, a first connecting rod rotatably mounted on the upper end of the lifting cylinder and rotatably fitted with the outer cylinder, and a second connecting rod rotatably mounted on the lower end of the lifting cylinder and rotatably fitted with the moving frame.

[0019] By adopting the above technical scheme, the beneficial effects of the present invention are as follows: when the wind direction is the wind in the positive front-back direction and the wind deviates from the left-right direction by less than 45 degrees, the heat dissipation modules of the front and rear side walls work, and the heat dissipation fans in the heat dissipation modules are in a state where one works and the other does not work. The wind will blow in from the heat dissipation fan on the non-working side, and after entering the substation body, it will blow out from the working heat dissipation fan on the other side, so that a circulation environment is formed inside the substation body, thereby better driving the heat dissipation in the substation body. When the wind direction exceeds the range of 90 degrees in the front-back direction, the wind will pass through the heat dissipation modules arranged in the left-right direction, and the heat dissipation modules in the left-right direction will start working. The heat dissipation modules in the front-back direction and the heat dissipation modules in the left-right direction can work alternately, and can adapt to the wind blowing from all directions around the substation body, so as to avoid affecting the heat dissipation effect of the substation body when strong winds blow.

[0032] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] like Figures 1 to 10 As shown, a specific embodiment of a prefabricated box-type substation of the present invention includes a substation body 10 and at least two groups of heat dissipation modules, one group is arranged on the front and rear side walls of the substation body 10, and the other group is arranged on the left and right side walls of the substation body 10. It is particularly noted that the structures and working principles of the two groups of heat dissipation modules are exactly the same, so the drawings of this embodiment only illustrate one group of heat dissipation modules arranged on the front and rear side walls.

[0034] Each heat dissipation module includes a heat dissipation unit, a driving unit, a transmission unit, a wind direction adjustment unit and a filtering unit.

[0035] like Figure 2 and Figure 3The heat dissipation unit includes two heat dissipation fans 20 respectively installed on the front and rear side walls of the substation body 10, and the front heat dissipation fan 20 is located in the lower left corner, and the rear heat dissipation fan 20 is located in the upper right corner, which can take away the heat inside the substation body 10 with the largest area.

[0036] Heat dissipation windows 24 are fixedly installed at positions corresponding to the heat dissipation fans 20 on the outer surface of the transformer substation body 10 to protect the heat dissipation fans 20 .

[0037] Each cooling fan 20 is equipped with a driving rod 21 , which is vertically arranged and rotatably mounted on the transformer substation body 10 . The driving unit can drive the driving rod 21 to rotate through the transmission unit, thereby controlling the cooling fan 20 to rotate.

[0038] like Figure 3 The driving unit includes a U-shaped mounting frame 30 fixedly mounted at the center of the top wall inside the substation body 10, a motor is mounted at the bottom of the mounting frame 30, a driving gear 31 driven by the motor is rotatably mounted inside the mounting frame 30, a driving column 32 is rotatably mounted on the substation body 10, and one driving column 32 is symmetrically arranged on both sides of the driving gear 31. A driven gear 33 is fixedly arranged at the end of each driving column 32, and each driven gear 33 is meshed with the driving gear 31, and both the driven gear 33 and the driving gear 31 are bevel gears. Thus, the driving gear 31 can drive the two driven gears 33 and the driving column 32 to rotate at the same time.

[0039] like Figure 4 , Figure 5 and Figure 6 Each driving column 32 is provided with a transmission unit, which includes an outer cylinder 50 sleeved on the outside of the driving column 32, and the outer cylinder 50 can slide horizontally along the axial direction of the driving column 32. A spring is provided at one end of the outer cylinder 50 to help it reset, and a push frame 53 is fixedly installed above the outer cylinder 50. An inner cylinder 51 connected to the driving column 32 by a key is rotatably installed inside the outer cylinder 50, so that the driving column 32 can drive the inner cylinder 51 to rotate, and a key slot 52 is provided on the inner wall of the inner cylinder 51.

[0040] A transmission rod 54 coaxial with the driving column 32 and having the same diameter as the driving column 32 is also rotatably mounted on the substation body 10, and there is a certain gap between the transmission rod 54 and the driving column 32. A bevel gear is provided at one end of the transmission rod 54 and the driving rod 21, and the two are meshed and connected.

[0041] The transmission rod 54 is provided with a groove, in which a matching block 55 is installed to slide up and down through a spring, and both ends of the matching block 55 are arc-shaped inclined surfaces. When the outer cylinder 50 and the inner cylinder 51 slide toward the transmission rod 54 along the driving column 32, the transmission rod 54 will enter the inner side of the inner cylinder 51. Since the outer diameter of the transmission rod 54 is the same as the inner diameter of the inner cylinder 51, the matching block 55 will be squeezed and stored in the groove first. When the inner cylinder 51 rotates outside the transmission rod 54, the matching block 55 encounters the keyway 52 on the inner cylinder 51, and the spring will push the matching block 55 out to enter the keyway 52. ​​At this time, the inner cylinder 51 will drive the transmission rod 54 to rotate together. At the same time, the transmission rod 54 drives the driving rod 21 to rotate, so that the heat dissipation fan 20 rotates and works.

[0042] like Figure 3 , Figure 4 and Figure 5 There are two wind direction adjustment units, which are respectively arranged corresponding to the two transmission units. The wind direction adjustment unit includes a rotating rod 40 that vertically penetrates the top wall of the substation body 10 and rotates with it. A wind direction plate 41 is fixedly arranged on the upper end of the rotating rod 40. The cross section of the wind direction plate 41 is triangular, which can facilitate it to distinguish the wind direction in the front and rear directions, so that it can rotate according to the wind direction, and can also determine which side the wind in the same horizontal direction is blowing from.

[0043] A top block 42 is fixedly provided at the lower end of the rotating rod 40. In this embodiment, the top block 42 is a semicircular structure. When the wind deflector 41 rotates according to the wind direction, the rotating rod 40 drives the top block 42 to rotate, and the top block 42 can push the push frame 53 to move, thereby controlling the working state of the cooling fan 20.

[0044] The two cooling fans 20 on each cooling unit have two working states, one state is: one cooling fan 20 is working and the other is not working; the other state is: both cooling fans 20 are not working. How to achieve this will be described in detail below.

[0045] It is particularly noted that in the two sets of wind direction adjustment units, the installation positions of the top blocks 42 on the rotating rod 40 are the same. That is, the two top blocks 42 are oriented in the same direction. Since the driving columns 32 are symmetrically arranged on both sides of the driving gear 31, the two sets of transmission units are also arranged in mirror symmetry. The two top blocks 42 are oriented in the same direction, so that when the arc surface of the top block 42 on one side conflicts with the push frame 53, the horizontal surface of the top block 42 on the other side conflicts with the push frame 53. In this way, a state in which one cooling fan 20 is working and the other is not working can be achieved.

[0046] When the wind direction is the front-to-back direction, the wind direction plates 41 are all arranged in the front-to-back direction. At this time, when the arc surface of the top block 42 on one side contacts the push frame 53, the horizontal surface of the top block 42 on the other side contacts the push frame 53. The arc surface of the top block 42 contacts the push frame 53, and the outer cylinder 50 can be pushed to move. The spring is compressed, and the matching block 55 is separated from the inner cylinder 51. The heat dissipation fan 20 on this side does not work. The horizontal surface of the top block 42 contacts the push frame 53, and the elastic force of the spring is released. The spring pushes the outer cylinder 50 to move, and the matching block 55 enters the inner side of the inner cylinder 51. As the inner cylinder 51 rotates, the matching block 55 will be clamped into the key slot 52, so that the driving column 32 drives the transmission rod 54 to rotate, driving the heat dissipation fan 20 on this side to work.

[0047] Wind will blow in from the cooling fan 20 on the non-working side, enter the substation body 10, and then blow out from the working cooling fan 20 on the other side, so that a circulating environment is formed inside the substation body 10, thereby better driving the heat inside the substation body 10 to dissipate.

[0048] It is particularly emphasized that the wind direction plate 41 can rotate with the wind direction, and the rotation angle of each wind direction plate 41 is 360 degrees. In this embodiment, when the wind direction is the wind in the positive front-back direction (perpendicular to the wind direction in the left-right direction) and the wind deviates from the left-right direction by less than 45 degrees, the cooling fan 20 is in a state where one is working and the other is not working.

[0049] The rotation range of the wind direction plate 41 includes the range perpendicular to the left and right directions and within 45 degrees to the left or right. That is, when the wind direction is within the two 90-degree ranges, one of the two cooling fans 20 in the front and rear directions is in a state of working and the other is not working. The cross section of the wind direction plate 41 is triangular, which can distinguish which side the wind direction in the front and rear directions is blowing from.

[0050] When the wind direction exceeds the range of 90 degrees in the front-to-back direction, the two cooling fans 20 in the front-to-back direction are not in working state. At this time, the wind will pass through the cooling modules arranged in the left and right directions, and the cooling modules in the left and right directions start to work, and the working state of the cooling fans 20 on the cooling modules in the left and right directions is one working and the other not working.

[0051] The heat dissipation modules in the front and rear directions and the heat dissipation modules in the left and right directions can work alternately and can adapt to the wind blowing from all directions around the substation body 10. It is particularly emphasized that only when the wind force reaches a certain size can the wind deflector 41 be pushed to rotate. Because the wind deflector 41 needs to push the outer cylinder 50 to move, it needs to overcome the elastic force of the spring on the outer cylinder 50.

[0052] The top block 42 is a semicircular structure, that is, the top block 42 has an arc surface and a horizontal surface. When the horizontal surface conflicts with the push frame 53, since the wind deflector 41 is within the range of 90 degrees in front and back or left and right, one of the two cooling fans 20 is in a working state and the other is not working. Therefore, the rotation angle of the horizontal surface of the top block 42 is divided into a 90-degree area at the center position and two 45-degree areas on both sides. When the top block 42 conflicts with the 90-degree area of ​​the horizontal plane rotation, the cooling fan 20 on this side is in a working state. When the top block 42 conflicts with the two 45-degree areas of the horizontal plane, at this time, the top block 42 has pushed the push frame 53 to move a distance, and the cooling fan 20 is not working. Similarly, the arc surface on the top block 42 is also divided into a 90-degree area and two 45-degree areas, but in this area, the top block 42 is in a state of pushing the push frame 53, so when the push frame 53 conflicts with the arc surface of the top block 42, the cooling fan 20 is not working.

[0053] It is particularly noted that when the horizontal surface of the top block 42 contacts the push frame 53, the heat dissipation fan 20 is in working state. However, as the horizontal surface of the top block 42 rotates, the horizontal surface will also drive the push frame 53 to move. Taking the radial direction of the middle position of the top block 42 as the reference, when the top block 42 rotates more than 45 degrees in the left and right directions (that is, the rotation angle of the horizontal surface of the top block 42 is in the 90-degree area of ​​the center position), the push frame 53 moves to a certain threshold, and the matching block 55 will be separated from the inner cylinder 51, and the heat dissipation fan 20 stops working. The threshold is the distance that the outer cylinder 50 moves, which can be achieved by setting.

[0054] like Figures 8 to 10 The filtering unit includes a mobile frame 60 horizontally slidably mounted on the transformer substation body 10. The mobile frame 60 corresponds to the cooling fan 20, and one is provided at each cooling fan 20. A plurality of filters 61 are vertically arranged on the mobile frame 60. The filter 61 is located on the air outlet side of the cooling fan 20. The lower end of the filter 61 is rotatably matched with the transformer substation body 10 through a pin shaft. A rotating column 62 is provided at the upper end. A guide groove 63 is provided on the front and rear side walls of the mobile frame 60. The rotating column 62 is located in the guide groove 63. When the mobile frame 60 moves horizontally, it will drive all the filters 61 to rotate around the lower end. At this time, all the filters 61 change from a vertical state to an inclined state. When the filter 61 is in a vertical state, there is no gap between all the filters 61, and a complete filtering component will be formed. When the filter 61 is in an inclined state, an opening will be formed between adjacent filters 61.

[0055] A lifting cylinder 64 is slidably mounted on the outer side of the rotating rod 40, a first connecting rod 65 is rotatably mounted on the upper end of the lifting cylinder 64, and the other end of the first connecting rod 65 is rotatably mounted on the outer cylinder 50, a second connecting rod 66 is rotatably mounted on the lower end of the lifting cylinder 64, and the other end of the second connecting rod 66 is rotatably mounted on the moving frame 60.

[0056] When the cooling fan 20 is not in operation, it indicates that the cooling fan 20 on this side is located at the air inlet. At this time, the filter 61 is in a vertical state, and the filter 61 forms a complete filter component to filter the incoming air to prevent dust from entering and causing damage to internal components.

[0057] When the outer cylinder 50 moves and the heat dissipation fan 20 is in working state, the outer cylinder 50 drives the lifting cylinder 64 to descend, pulling the movable frame 60 to move outward, and all the filters 61 are changed from a vertical state to an inclined state. Openings are formed between adjacent filters 61, and the heat dissipation fan 20 blows air outward to blow the internal dust to the outside.

[0058] Because the heat dissipation fan 20 works on one side and does not work on the other side, the filter 61 is also in a vertical state on one side and inclined on the other side. The air needs to be filtered by the filter 61 when entering, but does not need to pass through the filter 61 when discharged, so the dust inside can be taken out.

[0059] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
