Description

Technical Field

[0001] The invention relates to the technical field of electric power equipment boxes, and in particular to a special electric power equipment box. Background Art

[0002] Containerized power equipment box integrates power equipment, control systems and necessary auxiliary facilities in a standardized container to form a power supply unit with independent operation capabilities. This design concept combines modularization and integration ideas, aiming to improve the construction efficiency of power facilities, reduce maintenance costs, and enhance the flexibility and reliability of power supply through standardized and prefabricated production methods.

[0003] A Chinese patent with authorization announcement number CN205622055U discloses an air intake, rainproof and dustproof device for a container room of electric power equipment, comprising a dustproof window frame arranged at a vent of a container shell, dustproof shutters embedded in the front of the dustproof window frame, and a dustproof net arranged in the dustproof window frame. The rear end of the top of the dustproof window frame is inclined forward to the front end, and the upper side to the lower side of the dustproof shutter and the dustproof net are inclined inward. A dustproof net guide groove for installing and fixing the dustproof net is arranged in the dustproof window frame, and an opening for inserting and removing the dustproof net and a dustproof cover for closing the opening are arranged at the top of the dustproof net guide groove of the dustproof window frame. The patent protects the air intake structure of the container from rain and dust, and when replacing the dustproof net, it is only necessary to open the dustproof cover to pull out the dustproof net without opening the door of the container shell and without shutting down the electric power equipment, thereby improving maintenance efficiency and reducing the impact on the operation of the power system.

[0004] The existing special power equipment boxes have different usage environments according to different usage requirements. When used in the field, there is heavy fog in the early morning and high humidity on rainy days. Dehumidification of the special power equipment boxes is necessary to maintain their normal use. The existing equipment boxes will use desiccant to absorb moisture, but when replacing the desiccant, the desiccant close to the air inlet side will get wet first. If the other part of the desiccant is still dry, it will cause waste. When the desiccant is completely wet and then replaced, the desiccant has reached saturation and has lost its effect on drying the air. There is already moisture in the equipment box, and it is difficult to grasp the timing of replacing the desiccant. Summary of the invention

[0005] The present invention provides a special power equipment box, aiming to solve the existing special power equipment box in the related technology. According to different use requirements, the use environment is also different. When used in the field environment, the fog is heavy in the early morning and the humidity is high on rainy days. Dehumidification of the special power equipment box is necessary to maintain its normal use. The existing equipment box will use a desiccant to absorb moisture, but when the desiccant is replaced, the desiccant close to the air inlet side will get wet first. If the other part of the desiccant is still in a dry state, it will cause waste. When the desiccant is completely wet and then replaced, the desiccant has reached saturation and has lost the effect of drying the air. There is already moisture in the equipment box, and the timing of replacing the desiccant is difficult to grasp. Technical problem.

[0006] A special power equipment box of the present invention comprises: a box body, an air inlet and an air outlet arranged in the front and rear directions of the box body, a drying module is rotatably installed at the air inlet, the drying module comprises a shell, a drying unit and a storage unit, a drying chamber and ventilation holes penetrating the front and rear side walls are arranged in the shell body; the drying unit comprises a driving assembly, a drying assembly and a partition assembly; the driving assembly comprises a driving frame rotating in the drying chamber, two arc-shaped filter plates symmetrically fixed on the driving frame, and the filter plates respectively correspond to the ventilation holes in the front and rear directions; the drying assembly comprises a bearing frame rotatably connected to the driving frame by a spring, and a plurality of partitions fixed on the bearing frame at vertical intervals, and the front and rear ends of the partitions respectively abut against the filter plates on both sides, A accommodating chamber is formed between adjacent partitions, which is connected front to back and corresponds to the air inlet. The accommodating chamber is used to carry desiccant. A limit block is provided in the shell, and the limit block is located in the movement path of the carrier to limit the rotation angle of the carrier; the partition component includes storage grooves arranged on the partitions in the front and back directions, and a closing plate sliding in the storage groove and having air holes. When the rear closing plate slides out, the desiccant can be confined between the rear closing plate and the front filter plate. When the front closing plate slides out, the desiccant can be divided into two parts; the storage unit includes a storage chamber which is arranged at the upper and lower ends of the shell and is connected to the drying chamber, an opening and closing assembly arranged in the storage chamber to control the falling of materials, and a drying component arranged in the storage chamber.

[0007] The driving frame drives the carrier frame to rotate. When the carrier frame rotates to 90 degrees, it is restricted and cannot continue to rotate. At this time, all the partitions are in a vertical state, and the wet part of the desiccant is at the bottom. When the carrier frame rotates, the closing plate near the front side extends from the storage slot, thereby separating the desiccant in the storage chamber into two parts, separating the wet part of the desiccant, and at the same time, the closing plate near the rear side shrinks into the storage slot. The driving frame will continue to rotate to 180 degrees, and the wet part of the desiccant will fall into the storage chamber below, and then be dried by the drying component. The storage chamber above will replenish the desiccant into the storage chamber. Then the driving frame starts to drive the carrier frame to rotate and reset. The closing plate near the front side first shrinks into the storage slot. As the carrier frame continues to rotate, the desiccant in the storage chamber will gradually move to the air intake side, and then the closing plate near the rear side extends from the storage slot to push the desiccant to the front side to compact it, so as to prevent the desiccant from loosening, until the driving frame drives the carrier frame to rotate to the original position. When the desiccant in the upper storage chamber is used up, the shell is turned 180 degrees, and the positions of the upper and lower storage chambers are swapped, and the cycle is repeated.

[0008] Preferably, the storage groove and the closing plate are both arc-shaped structures.

[0009] Preferably, two groups of driving plates are slidably installed on the partition in the front-to-back direction. The driving plates are vertically arranged and springs are installed on the driving plates. The springs are connected to the partition at one end away from the driving plates. A plurality of driving grooves are opened in the vertical direction on each driving plate. A shift rod is provided on the closing plate, and the shift rod is located in the corresponding driving groove. A push plate is provided on the accommodating chamber. The push plate is an arc-shaped structure, and one end thereof is pointed. The push plate is located on the rotation path of the driving plate.

[0010] When the carrier is rotating, the closing plate can slide in the receiving groove through the driving plate.

[0011] Preferably, the opening and closing assembly includes a blanking rack installed in the material storage chamber, and a plurality of material discharge channels which pass through the blanking rack are horizontally arranged, and a first opening and closing plate is connected to the side of the blanking rack close to the drying chamber through a spring for horizontal sliding, and a second opening and closing plate is connected to the side of the blanking rack close to the material storage chamber through a spring for horizontal sliding, and the first opening and closing plate and the second opening and closing plate are matched through transmission assembly, and a connecting plate is provided on the first opening and closing plate, and a push bar is fixedly connected to the driving frame, and the connecting plate is located on the movement path of the push bar.

[0012] The connection or closing of the material storage cavity, the material discharge channel and the accommodating chamber is controlled by the first opening and closing plate and the second opening and closing plate.

[0013] Preferably, the transmission assembly includes a second gear rotatably mounted on the housing, and racks are provided on the first opening and closing plate and the second opening and closing plate, and the two racks are meshed with the second gear.

[0014] The first opening and closing plate and the second opening and closing plate can move simultaneously through the transmission assembly.

[0015] Preferably, two air inlets are horizontally arranged, a mounting frame is fixedly installed at the air inlet, two groups of shells are arranged, the two groups of shells correspond to the two air inlets respectively, the two groups of shells are fixed to each other, and are rotatably installed on the mounting frame.

[0016] Preferably, the driving frame is two circular rings rotatably mounted on the left and right sides of the drying chamber respectively, the filter plate is fixed between the two circular rings, one of the circular rings is provided with teeth, and a first gear meshing with the teeth is rotatably mounted in the shell, and the first gear is driven by a motor.

[0017] Preferably, the drying component is an electric heating wire installed in the material storage cavity.

[0018] The heating wire can increase the temperature in the storage chamber, thereby heating the wet desiccant and drying it.

[0019] By adopting the above technical scheme, the beneficial effects of the present invention are as follows: the driving frame drives the bearing frame to rotate, and when the bearing frame rotates to 90 degrees, it is restricted and cannot continue to rotate. At this time, all the partitions are in a vertical state, and the wet part of the desiccant is at the bottom. When the bearing frame rotates, the closing plate near the front side extends from the storage slot, thereby separating the desiccant in the receiving chamber into two parts, separating the wet part of the desiccant, and at the same time, the closing plate near the rear side shrinks into the receiving slot. The driving frame will continue to rotate to 180 degrees, and the wet part of the desiccant will fall into the storage chamber below, and then be dried by the drying component. The storage chamber above will replenish the desiccant into the receiving chamber. Then the driving frame starts to drive the bearing frame to rotate and reset, and the closing plate near the front side first shrinks into the receiving slot. As the bearing frame continues to rotate, the desiccant in the receiving chamber will gradually move to the air inlet side, and then the closing plate near the rear side extends from the storage slot to push and compact the desiccant to the front side to prevent the desiccant from loosening, until the driving frame drives the bearing frame to rotate to the original position. When the desiccant in the upper storage chamber is used up, the shell is turned 180 degrees, and the upper and lower storage chambers are swapped, so that the cycle continues. There is no need to manually replace the desiccant, and the desiccant near the wet part of the front side can be continuously discharged, and new desiccant can be added at the same time, so as to realize the step-by-step replacement of the desiccant, which not only effectively ensures the drying effect in the box, but also realizes the reuse of the desiccant.

[0031] 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.

[0032] like Figures 1 to 10 As shown, a specific embodiment of a special power equipment box of the present invention includes a box body 10 and two groups of drying modules; each group of drying modules includes a carrying unit, a drying unit and a storage unit.

[0033] like Figure 1 , Figure 2 Figure 3 and Figure 4 As shown, in this embodiment, the box 10 is a rectangular structure, and electrical components are installed inside. For ease of understanding, the length direction of the box 10 is defined as the left-right direction of this embodiment, and the width direction is defined as the front-back direction.

[0034] Two air inlets 11 are horizontally opened on the front side wall of the box body 10, and an air outlet 12 is opened on the rear side wall of the box body 10. Air can enter the box body 10 from the air inlets 11 and then be discharged from the air outlet 12 to cool the electrical components.

[0035] A mounting frame 13 is fixedly installed at a position corresponding to the air inlet 11 inside the box 10, and a through opening is opened on the mounting frame 13 at positions corresponding to the two air inlets 11. A driving motor 14 is fixedly installed on the surface of the mounting frame 13 away from the air inlet 11, and the driving motor 14 is located at the center of the mounting frame 13. A connecting block 15 is fixedly installed at the output end of the driving motor 14, and two groups of drying modules are fixedly installed on the left and right side surfaces of the connecting block 15, respectively, so that the driving motor 14 can drive the two drying modules to rotate. The two groups of drying modules are respectively arranged corresponding to the two air inlets 11.

[0036] like Figure 3 , Figure 5 and Figure 6 The bearing unit includes a housing 20, which is fixedly mounted on the connecting block 15. The driving motor 14 can drive the housing 20 to rotate through the connecting block 15. There is a certain distance between the top of the housing 20 and the top wall of the box body 10, ensuring that the housing 20 has enough rotation space.

[0037] The housing 20 has a drying chamber 21 extending therethrough from left to right. The cross section of the drying chamber 21 is circular.

[0038] The front and rear side walls of the housing 20 are both provided with square ventilation holes 22 of the same size, and the front and rear ventilation holes 22 are both connected to the drying chamber 21. The ventilation holes 22 on the front side of the housing 20 are arranged corresponding to the air inlet 11, so that air can enter the drying chamber 21 through the ventilation holes 22 on the front side, and then be exhausted from the ventilation holes 22 on the rear side after being dried by the drying unit, and finally be exhausted from the air outlet 12.

[0039] like Figures 5 to 9 As shown, the drying unit includes a driving component, a drying component and a partitioning component.

[0040] The driving assembly includes a driving frame 30 rotatably mounted in the drying chamber 21. The driving frame 30 is two circular rings rotatably mounted on the left and right sides of the drying chamber 21, and the circular rings are coaxially arranged with the drying chamber 21. Two filter plates 32 are fixedly connected between the two circular rings. Both filter plates 32 are arc-shaped structures and are arranged front and back oppositely. The filter plate 32 on the front side corresponds to and closes the ventilation hole 22 on the front side, and the filter plate 32 on the rear side corresponds to and closes the ventilation hole 22 on the rear side.

[0041] The ring on one side of the driving frame 30 is provided with teeth, and a first gear 31 meshing with the teeth is rotatably installed in the housing 20. The first gear 31 is driven by a motor to rotate the driving frame 30. In this embodiment, the driving frame 30 can rotate 180 degrees.

[0042] Continue to refer Figures 5 to 9 The drying assembly includes a carrier frame 40 rotatably mounted on the driving frame 30. The carrier frame 40 is also composed of two annular structures, and the two annular structures are rotatably mounted on two circular rings of the driving frame 30 respectively, and the driving frame 30 and the carrier frame 40 are coaxially arranged.

[0043] A plurality of partitions 41 are vertically arranged at intervals inside the carrier frame 40, and the left and right ends of the partitions 41 are fixedly connected to the annular structures on both sides (such as Fig. 9 ). The front and rear sides of the partition 41 are respectively in contact with the filter plates 32 on both sides, and a receiving chamber is formed between two adjacent partitions 41, and the left and right directions of the receiving chamber are both sealed. Thus, air can pass through the filter plate 32 on the front side (inlet side), enter all the receiving chambers at the same time, and then pass through the filter plate 32 on the rear side (outlet side).

[0044] A linkage spring 33 (such as Fig. 9), a mounting block 49 is fixedly provided on the inner side surface of the carrier frame 40, one end of the linkage spring 33 is fixedly connected to the mounting block 49, and the other end is fixedly connected to the driving frame 30. When the driving frame 30 rotates, the carrier frame 40 can be pulled to rotate by the linkage spring 33. In this embodiment, a limit block (not shown in the figure) is provided on the movement path of the mounting block 49. The limit block is provided on the shell 20. The limit block can be provided along the radial sliding of the carrier frame 40, for example, it can be driven by an electromagnet, and only when the mounting block 49 is close to the limit block, the limit block extends to block the mounting block 49. When the driving frame 30 drives the carrier frame 40 to rotate 90 degrees together, the mounting block 49 will abut against the limit block, thereby limiting the mounting block 49 and the carrier frame 40 from continuing to rotate, so that the maximum rotation angle of the carrier frame 40 is 90 degrees. The driving frame 30 continues to rotate until the driving frame 30 rotates to 180 degrees. When the supporting frame 40 stops rotating, the driving frame 30 continues to rotate, and the linkage spring 33 is in a continuously stretched state until the driving frame 30 rotates to 180 degrees and stops.

[0045] There are two groups of partition components, which are arranged at intervals along the front-to-back direction of the accommodating chamber. The partition components include a receiving groove 42 opened on the bottom partition 41 of the accommodating chamber, and each bottom partition 41 of the accommodating chamber is provided with a receiving groove 42 in the vertical direction. The receiving groove 42 is an arc-shaped structure, and one end is connected to the accommodating chamber. In other words, two receiving grooves 42 are provided at intervals on the bottom partition 41 of each accommodating chamber, that is, one receiving groove 42 is located on the air inlet side (front side) of the shell 20, and the other receiving groove 42 is located on the air outlet side (rear side).

[0046] An arc-shaped closing plate 43 is slidably installed in the storage groove 42. The closing plate 43 is covered with air holes. When the closing plate 43 slides out of the storage groove 42, its end just abuts against the top wall of the accommodating chamber, thereby dividing the accommodating chamber into multiple small chambers.

[0047] A driving plate 45 is installed on the side of the partition 41 to slide in the front-back direction. The driving plate 45 is vertically arranged and a spring is installed thereon. The other end of the spring is connected to the partition 41, which can help the driving plate 45 to reset after sliding. A plurality of driving grooves 46 are opened on the driving plate 45 in the vertical direction. Each driving groove 46 corresponds to the closing plate 43. A lever 44 is provided on the closing plate 43, and the lever 44 is located in the corresponding driving groove 46. When the driving plate 45 in each group slides, all the closing plates 43 in each group can be driven to slide out of the storage groove 42 or be stored in the storage groove 42 from the outside.

[0048] A push plate 47 is provided on the accommodating chamber. The push plate 47 is an arc-shaped structure with one end being pointed. The push plate 47 is located on the rotation path of the driving plate 45. When the driving plate 45 reaches the push plate 47, it can force the driving plate 45 to slide, thereby driving the closing plate 43 to slide.

[0049] It is particularly emphasized that, of the two driving plates 45 on the front and rear sides, the driving plate 45 close to the air inlet side will first contact the push plate 47, thereby first driving the closing plate 43 to slide. The driving plate 45 close to the air outlet side will contact the push plate 47 later.

[0050] In normal working state (such as Figure 5 As shown in the figure, the closing plate 43 near the air inlet side is located in the storage groove 42, and the closing plate 43 near the air outlet side extends to the outside of the storage groove 42, that is, each closing plate 43 near the air outlet side divides each layer of the storage chamber into two parts, and the chamber between the closing plate 43 and the front filter plate 32 is filled with desiccant. The air on the front side passes through the front filter plate 32 and enters the storage chamber, and then after being dried by the desiccant, it passes through the closing plate 43 near the air outlet side and the rear filter plate 32 in turn and enters the box body 10, and then is discharged from the air outlet 12, completing the drying of the air while ventilating the box body 10.

[0051] like Figure 5 and Figure 6 As shown, two groups of material storage units are provided, which are respectively arranged at the upper and lower ends of the housing 20. Each group of material storage units includes a material storage cavity 50, a feeding channel 51 and an opening and closing component.

[0052] The storage chambers 50 of the two storage units are respectively located at the upper and lower ends of the housing 20, and the storage chambers 50 are connected with feeding channels 51. At the same time, the feeding channels 51 are connected with the drying chamber 21. The storage chambers 50 are used to store desiccant, which can be replenished in the accommodating chamber. A drying component is provided in the storage chamber 50 to dry the desiccant. In this embodiment, the drying component is a heating wire.

[0053] The feeding channel 51 is provided with an opening and closing assembly to control the dropping of the desiccant. The opening and closing assembly includes a dropping rack 52 installed in the feeding channel 51, and a plurality of dropping channels that pass through the dropping rack 52 are horizontally arranged. A first opening and closing plate 53 is connected to the side of the dropping rack 52 close to the drying chamber 21 by a spring for horizontal sliding, and a second opening and closing plate 54 is connected to the side of the dropping rack 52 close to the storage chamber 50 by a spring for horizontal sliding. The first opening and closing plate 53 and the second opening and closing plate 54 can control the opening and closing of the openings at both ends of the dropping channel on the dropping rack 52.

[0054] Racks 55 are fixedly mounted on the first opening and closing plate 53 and the second opening and closing plate 54 , and the two racks 55 are transmission-connected via a second gear 56 , so that when the first opening and closing plate 53 slides, the second opening and closing plate 54 can be driven to slide synchronously.

[0055] It is particularly emphasized that the opening and closing states of the first opening and closing plate 53 and the second opening and closing plate 54 for the material discharge channel are opposite, for example, when the first opening and closing plate 53 is in an open state for the material discharge channel, the second opening and closing plate 54 is in a closed state for the material discharge channel. In a normal state, the second opening and closing plate 54 is always kept in an open state.

[0056] A connecting plate 57 is provided on the first opening and closing plate 53, and a pushing bar 58 is fixedly connected to the driving frame 30. When the driving frame 30 rotates to 180 degrees, the pushing bar 58 can push the connecting plate 57 to move, so that the first opening and closing plate 53 and the second opening and closing plate 54 slide at the same time, so that the first opening and closing plate 53 opens the unloading channel, and the second opening and closing plate 54 closes the unloading channel.

[0057] After working for a certain period of time, a part of the desiccant in the storage chamber near the air inlet side will be wet first, so that this part is saturated. When replacing the desiccant, the driving frame 30 drives the carrier frame 40 to rotate. When the carrier frame 40 rotates to 90 degrees, it is restricted and cannot continue to rotate. At this time, all the partitions 41 are in a vertical state, and the wet part of the desiccant is at the bottom in the vertical direction. When the carrier frame 40 rotates to 90 degrees, the closing plate 43 near the front side extends from the storage groove 42, thereby dividing the desiccant in the storage chamber into two parts, that is, separating the wet part of the desiccant, and at the same time, the closing plate 43 near the rear side shrinks into the storage groove 42 (such as Fig.10 At this time, the filter plates 32 on both sides are respectively located at the upper and lower parts of the accommodating chamber, and the desiccant in the upper storage chamber 50 is blocked and cannot fall down, and the wet part of the desiccant cannot be discharged.

[0058] Then the driving frame 30 will continue to rotate until it rotates 180 degrees. At this time, the filter plates 32 on both sides rotate to the horizontal direction again. At the same time, the upper and lower first opening and closing plates 53 are pushed to slide, and the side of the material discharge channel close to the drying chamber 21 is opened. The wet part of the desiccant will fall into the material discharge channel below, and when the second opening and closing plate 54 is opened, it will be discharged into the storage chamber 50 at the bottom, and then dried by the drying component.

[0059] The material discharge channel on the material discharge rack 52 is closed at the upper end and opened at the lower end. At this time, the desiccant in the storage chamber 50 can no longer enter the material discharge channel. Therefore, the desiccant in the material discharge channel falls into the corresponding receiving chambers to complete the addition of new desiccant. It is particularly emphasized that the multiple material discharge channels on the material discharge rack 52 correspond to the multiple vertical receiving chambers.

[0060] Then the driving frame 30 rotates in the opposite direction to reset, and the driving frame 30 first rotates 90 degrees to return. At this time, the first opening and closing plate 53 is reset, and the corresponding position of the material discharge channel is closed, and the second opening and closing plate 54 opens the corresponding position of the material discharge channel. The upper storage chamber 50 refills the desiccant into the lower material discharge channel, and the wet desiccant in the lower material discharge channel falls into the lower storage chamber 50 for drying.

[0061] Then the driving frame 30 starts to drive the supporting frame 40 to rotate and reset. The closing plate 43 near the front side first shrinks into the receiving groove 42. As the supporting frame 40 continues to rotate, the desiccant in the accommodating chamber will gradually move toward the air inlet side. Then the closing plate 43 near the rear side extends out from the receiving groove 42 to push and compact the desiccant toward the front side to prevent the desiccant from loosening and air from passing through the gaps in the desiccant, resulting in drying failure, until the driving frame 30 drives the supporting frame 40 to rotate to its original position.

[0062] When the desiccant in the upper storage chamber 50 is used up, the two shells 20 are turned over 180 degrees, and the positions of the upper and lower storage chambers 50 are swapped, and the cycle is repeated.

[0063] Simply put, the wet desiccant on the front side is isolated by a closing plate 43 close to the air inlet side. When the accommodating chamber is rotated 90 degrees, the wet desiccant on the front side is discharged into the storage chamber 50 below for recovery and drying. The storage chamber 50 above will refill the new desiccant into the accommodating chamber, thus completing the cycle.

[0064] 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.
