Description

Technical Field

[0001] This invention relates to the field of power supply equipment technology, and in particular to a power supply device for sewage treatment equipment used in tunnel construction. Background Technology

[0002] Tunnel construction generates various types of wastewater, including geological inrush water, equipment cooling wastewater, cleaning wastewater, blasting dust, and grouting leakage water. This wastewater contains large amounts of suspended solids, fluorides, heavy metals, petroleum substances, and organic pollutants. If discharged directly without treatment, it will lead to eutrophication and heavy metal accumulation in the water body. Therefore, a wastewater treatment system must be in place to ensure that the effluent meets Class III water quality standards and avoids damaging the fragile ecosystem. In addition, tunnel construction requires a large amount of water. Wastewater treatment equipment can reuse the purified water in the construction process. This closed-loop cycle significantly reduces the amount of water taken from outside, which is economically beneficial in areas with water shortages and high water transportation costs. However, when treating this wastewater, wastewater treatment equipment needs to be installed inside the tunnel, and a matching power supply cabinet is also required to power the wastewater treatment equipment.

[0003] It should be noted that during tunnel construction, the enclosed and highly humid environment results in high levels of dust and humidity. Power supply cabinets, which require heat dissipation, are typically equipped with cooling fans and filters. However, the high dust and humidity can easily cause these filters to become damp, condensed, and malfunction. Furthermore, the high humidity and large temperature differences within the tunnel cause the filters to absorb moisture, leading to reduced ventilation, increased internal temperature, and component overheating. In addition, the remote location and limited space of tunnel power supply cabinets mean that replacing or cleaning filters requires power outages, which is both time-consuming and poses significant safety risks. Summary of the Invention

[0004] The purpose of this invention is to provide a power supply device for sewage treatment equipment used in tunnel construction, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A power supply device for sewage treatment equipment used in tunnel construction includes a power supply cabinet, a cabinet door is movably installed on one side of the power supply cabinet, and a cooling fan is installed on the top side of the power supply cabinet. Two heat dissipation side holes are opened on both sides of the power supply cabinet, and a filter frame with a hollow interior is movably installed in the heat dissipation side holes. The filter frame is filled with moisture-absorbing particles. It also includes a shielding, drying, and unblocking mechanism, which is installed on the power supply cabinet and is used to dry and unblock the filter frame. The shielding, drying, and unblocking mechanism includes two shielding blowers, which are movably installed on both sides of the power supply cabinet. The shielding blowers are hollow and have multiple blower nozzles installed on their inner walls. An air collecting hood is installed on the top side of the power supply cabinet, and a transfer duct is installed on the air collecting hood. Both shielding blowers are connected to the transfer duct. A cleaning brush is movably installed inside the shielding blower, and the cleaning brush moves to clean and unblock the outside of the filter frame. The power supply cabinet is equipped with a linkage switching mechanism, which is used to move and switch the shielding, drying and unblocking mechanism. The linkage switching mechanism includes two switching cylinders, which are respectively installed on both sides of the power supply cabinet. A switching push rod is installed on the output shaft of the switching cylinder, and a switching mounting plate is installed on the switching push rod. The switching mounting plate is installed on the shielding blower cover.

[0007] Furthermore, in a preferred embodiment of the present invention, the shielding, drying and unblocking mechanism further includes two adapter blowers, the two adapter blowers being respectively mounted on the two shielding blowers; The adapter duct is connected to the two adapter blowers, and the adapter blowers are used to deliver the hot air blown out by the adapter duct into the shield blower.

[0008] Furthermore, in a preferred embodiment of the present invention, a blower motor is mounted on the adapter blower cover, and a blower shaft is mounted on the output shaft of the blower motor; Multiple blower blades are mounted equidistantly in a ring on the blower shaft, and all of the blower blades are located inside the adapter blower cover.

[0009] Furthermore, in a preferred embodiment of the present invention, a limiting frame is installed inside the shielding blower cover, and the cleaning brush is slidably installed inside the limiting frame; The cleaning brush is equipped with a linkage slide, the blower shaft is equipped with a rotating pusher, the rotating pusher is rotatably mounted with a linkage push shaft, and the linkage push shaft is movably mounted inside the linkage slide.

[0010] Furthermore, in a preferred embodiment of the present invention, the linkage switching mechanism further includes a plurality of load-bearing plates, which are respectively movably installed in a plurality of heat dissipation side holes; The filter frame is movably mounted on the load-bearing plate. When the filter frame becomes damp and heavy, it causes the load-bearing plate to move downwards.

[0011] Furthermore, in a preferred embodiment of the present invention, an installation cavity is provided on the bottom inner wall of the heat dissipation side hole, a pressure-bearing frame is movably installed in the installation cavity, and the load-bearing plate is installed on the pressure-bearing frame; A support spring is installed on the pressure-bearing frame, and the support spring is installed on the top inner wall of the mounting cavity.

[0012] Furthermore, in a preferred embodiment of the present invention, a switching switch is installed on the bottom inner wall of the mounting cavity, the switching switch is electrically connected to the switching cylinder, and the pressure frame moves down to trigger the switching switch.

[0013] Furthermore, in a preferred embodiment of the present invention, a synchronous sealing and blocking mechanism is also included. The synchronous sealing and blocking mechanism is installed inside the power supply cabinet and is used to seal the heat dissipation side hole. The synchronous sealing and blocking mechanism includes two inner sealing plates. Restriction grooves are provided on both inner walls of the power supply cabinet. The two inner sealing plates are slidably installed in the two restriction grooves respectively. The inner sealing plates are used to seal the heat dissipation side holes.

[0014] Furthermore, in a preferred embodiment of the present invention, mounting shafts are installed on both inner walls of the power supply cabinet, a switching pivot is rotatably mounted on the mounting shaft, and a switching plate is mounted on the switching pivot. The inner sealing plate is provided with a drive groove, and the switching rotating plate is rotatably mounted with a switching drive shaft, which is movably installed in the drive groove.

[0015] Furthermore, in a preferred embodiment of the present invention, two pressing push rods are movably installed on the inner walls of both sides of the power supply cabinet, and a driving push plate is installed on each of the two pressing push rods. Two switching push slots are opened on the switching rotary seat, and a switching push block is installed on each of the two driving push plates. The two switching push blocks are movably installed in the two switching push slots respectively. A connecting spring is installed on the drive push plate, and the connecting spring is installed on the inner wall of the power supply cabinet.

[0016] The beneficial effects of the power supply device for sewage treatment equipment in tunnel construction proposed in this invention are: In this invention, the shielding and drying mechanism allows hot air drawn by the cooling fan to enter the transfer duct through the air collector, and then into two transfer blower hoods. Simultaneously, the blower motor is activated, driving the blower shaft to rotate. This shaft, in turn, rotates multiple blower blades, which blow hot air into the shielded blower hoods. The hot air is then directed through multiple blower nozzles onto the filter frame shielded by the hoods, drying the moisture-absorbing particles within the filter frame and allowing for reuse. Furthermore, the rotation of the blower shaft moves a cleaning brush, which cleans the filter frame, ensuring its reusability. Therefore, through the dual drying process of desiccant and hot air, the filter frame remains continuously dry, preventing moisture from entering the cabinet, avoiding condensation and mold growth, improving insulation performance, reducing the risk of short circuits, and ensuring the safe operation of the power supply cabinet by circulating the hot air and balancing temperature and humidity.

[0017] Furthermore, in this invention, through the linkage switching mechanism, the filter frame is gradually blocked during continuous use. Simultaneously, as the moisture-absorbing particles gradually reach their limit, the filter frame moves downward, and the load-bearing plate drives the pressure frame to move downward, causing the support spring to be stretched. At this time, the pressure frame triggers the switching switch, which starts the switching cylinder and drives the switching mounting plate to move through the switching push rod. The movement of the switching mounting plate drives the shielding blower to move, thereby shielding the filter frame and exposing the other filter frame for use. This achieves automatic switching between the two filter frames in the power supply cabinet, thus ensuring that the heat dissipation channel is not interrupted.

[0018] Furthermore, in this invention, by setting up a synchronous sealing and blocking mechanism, when the shielding blower moves, the squeezing push rod at the corresponding position moves, causing the squeezing push rod to drive the push plate to move, which in turn causes the switching drive shaft to drive the inner sealing plate to move, thereby sealing the filter frame at the corresponding position and preventing hot air from entering the power supply cabinet.

[0027] Please refer to the attached instruction manual. Figures 1-11 The present invention provides a power supply device for sewage treatment equipment in tunnel construction, which includes a power supply cabinet 1, a cabinet door 2 movably installed on one side of the power supply cabinet 1, and a heat dissipation fan 3 installed on the top side of the power supply cabinet 1. Two heat dissipation side holes 4 are opened on both sides of the power supply cabinet 1. A filter frame 5 with a hollow interior is movably installed in the heat dissipation side holes 4, and the filter frame 5 is filled with moisture-absorbing particles 9.

[0028] Further, please refer to the appendix to the instruction manual. Figures 4-7 The present invention provides a power supply device for a sewage treatment equipment used in tunnel construction, which further includes a shielding, drying and unblocking mechanism 6. The shielding, drying and unblocking mechanism 6 is installed on the power supply cabinet 1 and is used to dry and unblock the filter frame 5. Specifically, the shielding, drying and unblocking mechanism 6 includes two shielding blowers 601, which are respectively movably installed on both sides of the power supply cabinet 1. The shielding blowers 601 are hollow and multiple blower nozzles 602 are installed on the inner wall of the shielding blowers 601. An air collecting hood 607 is installed on the top side of the power supply cabinet 1. A transfer air duct 608 is installed on the air collecting hood 607. Both shielding blowers 601 are connected to the transfer air duct 608. A cleaning brush 609 is movably installed inside the shielding blowers 601. The cleaning brush 609 moves to clean and unblock the outside of the filter frame 5.

[0029] It should be noted that, in this embodiment of the invention, when the blower hood 601 covers the filter frame 5, the cooling fan 3 dissipates heat from the power supply cabinet 1, and the hot air drawn out by the cooling fan 3 enters the transfer duct 608 through the air collector hood 607, and then enters the two transfer blower hoods 603 through the transfer duct 608. At the same time, the blower motor 604 is started, causing the blower motor 604 to drive the blower shaft 605 to rotate. The blower shaft 605 drives multiple blower fan blades 606 to rotate, causing the blower fan blades 606 to blow hot air into the blower hood 601, and then blows it onto the filter frame 5 covered by the blower hood 601 through multiple blower nozzles 602, thereby drying the moisture-absorbing particles 9 in the filter frame 5, so that the moisture-absorbing particles 9 can be reused. In addition, when the blower shaft 605 rotates, the cleaning brush 609 can also clean the filter frame 5, ensuring the reuse of the filter frame 5.

[0030] It should be emphasized that, in the embodiments of the present invention, the moisture-absorbing particles 9 can be made of commonly used drying materials such as ceramsite and desiccants, and the specific choice is best to meet the actual use requirements.

[0031] More specifically, in this embodiment of the invention, a linkage switching mechanism 7 is installed on the power supply cabinet 1. The linkage switching mechanism 7 is used to move and switch the shielding drying and unblocking mechanism 6. The linkage switching mechanism 7 includes two switching cylinders 701, which are respectively installed on both sides of the power supply cabinet 1. A switching push rod 702 is installed on the output shaft of the switching cylinder 701, and a switching mounting plate 703 is installed on the switching push rod 702. The switching mounting plate 703 is installed on the shielding blower hood 601. It should be noted that in this embodiment of the invention, when the filter frame 5 is gradually clogged after long-term use, and the moisture-absorbing particles 9 are gradually absorbed to their limit, the filter frame 5 moves down and triggers the switching switch 708, which in turn activates the switching cylinder 701. The switching push rod 702 drives the switching mounting plate 703 to move, and the movement of the switching mounting plate 703 drives the shielding blower hood 601 to move, thereby shielding the filter frame 5 and exposing the other filter frame 5 for use, ensuring the heat dissipation of the power supply cabinet 1.

[0032] Please continue to refer to the instruction manual appendix. Figures 4-7 Furthermore, the power supply device for a sewage treatment equipment for tunnel construction provided in this embodiment of the invention, the shielding, drying and dredging mechanism 6 also includes two adapter blowers 603, which are respectively installed on two shielding blowers 601. Furthermore, the adapter duct 608 is connected to two adapter blower hoods 603, which are used to transport the hot air blown out by the adapter duct 608 into the shield blower hood 601. It should be noted that, in this embodiment of the invention, when the cooling fan 3 is dissipating heat, the extracted hot air enters the adapter duct 608 through the air collector hood 607, and then enters the two adapter blower hoods 603 through the adapter duct 608, thereby achieving the purpose of reusing the hot air.

[0033] More specifically, in this embodiment of the invention, a blower motor 604 is installed on the adapter blower cover 603, and a blower shaft 605 is installed on the output shaft of the blower motor 604; multiple blower blades 606 are installed equidistantly in a ring on the blower shaft 605, and all the multiple blower blades 606 are located inside the adapter blower cover 603. It should be noted that, in this embodiment of the invention, when the blower motor 604 is started, the blower motor 604 drives the blower shaft 605 to rotate, so that the blower shaft 605 drives the multiple blower blades 606 to rotate. The blower blades 606 blow hot air into the shielding blower cover 601, and then blow it through multiple blower nozzles 602 towards the filter frame 5 which is shielded by the shielding blower cover 601, thereby achieving the purpose of drying the moisture-absorbing particles 9 in the filter frame 5.

[0034] More specifically, in this embodiment of the invention, a limiting frame 610 is installed inside the shielding blower cover 601, and the cleaning brush 609 is slidably installed inside the limiting frame 610. Furthermore, a linkage slide 611 is installed on the cleaning brush 609, a rotating push frame 612 is installed on the blower shaft 605, and a linkage push shaft 613 is rotatably installed on the rotating push frame 612, with the linkage push shaft 613 movably installed inside the linkage slide 611. It should be noted that in this embodiment of the invention, when the blower shaft 605 rotates, it drives the rotating push frame 612 to rotate, which in turn drives the linkage push shaft 613 to rotate. The rotation of the linkage push shaft 613 causes the linkage slide 611 to move, and the linkage push shaft 613 slides within the linkage slide 611. The linkage slide 611 moves horizontally within the limiting frame 610, and drives the cleaning brush 609 to move, thereby achieving the purpose of the cleaning brush 609 horizontally cleaning the filter frame 5.

[0035] Please refer to the instruction manual attached. Figures 4-5 and Figures 8-9 Furthermore, the power supply device for sewage treatment equipment in tunnel construction provided in this embodiment of the invention includes a linkage switching mechanism 7 that further comprises multiple load-bearing plates 705, which are movably installed in multiple heat dissipation side holes 4; a filter frame 5 is movably installed on the load-bearing plates 705, and the filter frame 5 becomes heavier when damp, causing the load-bearing plates 705 to move downwards. It should be noted that, in this embodiment of the invention, when the filter frame 5 is excessively damp, the load-bearing plate 705 causes the pressure-bearing frame 706 to move downwards, thereby achieving the purpose of automatically triggering the switching switch 708.

[0036] More specifically, in this embodiment of the invention, a mounting cavity 704 is provided on the bottom inner wall of the heat dissipation side hole 4. A pressure-bearing frame 706 is movably mounted in the mounting cavity 704, and a load-bearing plate 705 is mounted on the pressure-bearing frame 706. A support spring 707 is mounted on the pressure-bearing frame 706, and the support spring 707 is mounted on the top inner wall of the mounting cavity 704. It should be noted that in this embodiment of the invention, when the filter frame 5 becomes damp and moves downward, the load-bearing plate 705 drives the pressure-bearing frame 706 to move downward, and at the same time, the support spring 707 is stretched. Therefore, after the filter frame 5 is dried, the rebound force of the support spring 707 can make the filter frame 5 automatically reset, which is convenient for reuse.

[0037] Please continue to refer to the instruction manual appendix. Figures 4-5 and Figures 8-9More specifically, in this embodiment of the invention, a switching switch 708 is installed on the bottom inner wall of the mounting cavity 704. The switching switch 708 is electrically connected to the switching cylinder 701. The pressure frame 706 moves downward to trigger the switching switch 708. It should be noted that in this embodiment of the invention, when the filter frame 5 is excessively damp and moves downward, the load-bearing plate 705 drives the pressure frame 706 to move downward and triggers the switching switch 708, causing the switching cylinder 701 to start. This, in turn, drives the switching mounting plate 703 to move via the switching push rod 702. The movement of the switching mounting plate 703 causes the shielding blower hood 601 to move, thereby achieving the purpose of automatic movement of the shielding blower hood 601.

[0038] Please refer to the instruction manual attached. Figures 9-11 Furthermore, the power supply device for sewage treatment equipment for tunnel construction provided in this embodiment of the invention also includes a synchronous sealing and blocking mechanism 8, which is installed inside the power supply cabinet 1 and is used to seal the heat dissipation side hole 4. Specifically, the synchronous sealing and blocking mechanism 8 includes two inner sealing plates 801. Restriction grooves 802 are provided on both inner walls of the power supply cabinet 1. The two inner sealing plates 801 are slidably installed within the two restriction grooves 802, and are used to seal the heat dissipation side holes 4. It should be noted that in this embodiment of the invention, when the shielding blower hood 601 moves, the switching drive shaft 805 drives the inner sealing plates 801 to move, thereby achieving the purpose of sealing the filter frame 5 at the corresponding position and preventing hot air from entering the power supply cabinet 1.

[0039] More specifically, in this embodiment of the invention, mounting shafts 806 are installed on both inner walls of the power supply cabinet 1. A switching pivot 803 is rotatably mounted on the mounting shaft 806, and a switching pivot plate 804 is mounted on the switching pivot 803. Furthermore, a drive groove 811 is provided on the inner sealing plate 801, and a switching drive shaft 805 is rotatably mounted on the switching pivot plate 804, movably installed within the drive groove 811. It should be noted that in this embodiment of the invention, when the switching pivot 803 rotates, it rotates on the mounting shaft 806, and the rotation of the switching pivot 803 drives the switching pivot plate 804 to rotate. The rotation of the switching pivot plate 804 drives the switching drive shaft 805 to rotate, causing the switching drive shaft 805 to move the inner sealing plate 801. Simultaneously, the switching drive shaft 805 slides within the drive groove 811, thereby achieving the purpose of lateral movement of the inner sealing plate 801 when the switching pivot plate 804 rotates.

[0040] Please continue to refer to the instruction manual appendix. Figures 9-11More specifically, in this embodiment of the invention, two extrusion push rods 808 are movably installed on the inner walls of both sides of the power supply cabinet 1. A drive push plate 807 is installed on each of the two extrusion push rods 808. Two switching push slots 809 are opened on the switching rotary seat 803. A switching push block 810 is installed on each of the two drive push plates 807. The two switching push blocks 810 are movably installed in the two switching push slots 809 respectively. In addition, a connecting spring 812 is installed on the drive push plate 807, and the connecting spring 812 is installed on the inner wall of the power supply cabinet 1. It should be noted that, in this embodiment of the invention, when the shielding blower cover 601 moves, the pressing push rod 808 at the corresponding position moves, causing the pressing push rod 808 to drive the drive push plate 807 to move, and causing the connecting spring 812 to be stressed. At the same time, the movement of the drive push plate 807 causes the switching push block 810 to move in the switching push groove 809 on the corresponding side, causing the switching rotary seat 803 to rotate, thereby causing the switching drive shaft 805 to drive the inner sealing plate 801 to move, so as to achieve the purpose of automatic movement of the inner sealing plate 801.

[0041] In summary, the working principle of the power supply device for sewage treatment equipment in tunnel construction provided by this embodiment of the invention is as follows: When the power supply cabinet 1 is in use, air enters the power supply cabinet 1 through the filter frame 5. Since the air in the tunnel is dusty and humid, the filter frame 5 can not only filter the air, but also absorb the moisture in the air through the moisture-absorbing particles 9 to ensure the safety of the power supply equipment in the power supply cabinet 1. When the filter frame 5 is used continuously, the filter frame 5 gradually becomes clogged. At the same time, as the moisture-absorbing particles 9 gradually absorb to their limit, the filter frame 5 moves down and drives the bearing frame 706 to move down through the load-bearing plate 705. At the same time, the support spring 707 is stretched by force. At this time, the bearing frame 706 triggers the switching switch 708, which starts the switching cylinder 701 and drives the switching mounting plate 703 to move through the switching push rod 702. The movement of the switching mounting plate 703 drives the shielding blower 601 to move, thereby making the shielding blower 601 cover the filter frame 5, while exposing the other filter frame 5 for use, to ensure the heat dissipation of the power supply cabinet 1. Furthermore, the power supply cabinet 1 is cooled by the cooling fan 3, and the hot air drawn out by the cooling fan 3 enters the transfer duct 608 through the air collector 607, and then enters the two transfer blower hoods 603 through the transfer duct 608. At the same time, the blower motor 604 is started, which drives the blower shaft 605 to rotate. The blower shaft 605 drives multiple blower blades 606 to rotate, so that the blower blades 606 blow hot air into the shield blower hood 601, and then blows it onto the filter frame 5 which is shielded by the shield blower hood 601 through multiple blower nozzles 602. This process dries the moisture-absorbing particles 9 inside the filter frame 5, allowing them to be reused. Furthermore, when the blower shaft 605 rotates, it drives the rotating pusher 612 to rotate, which in turn drives the linkage pusher 613 to rotate. The rotation of the linkage pusher 613 causes the linkage slide 611 to move, while the linkage pusher 613 slides within the linkage slide 611. The linkage slide 611 moves horizontally within the limiting frame 610, driving the cleaning brush 609 to move. This allows the cleaning brush 609 to clean the filter frame 5, ensuring its reuse. Furthermore, when the shielding blower cover 601 moves, the pressing push rod 808 at the corresponding position moves, the pressing push rod 808 drives the drive push plate 807 to move, and causes the connecting spring 812 to be stressed. The drive push plate 807 moves, causing the switching push block 810 to move in the switching push groove 809 on the corresponding side, which in turn drives the switching rotating seat 803 to rotate. The switching rotating seat 803 rotates on the mounting shaft 806. The rotation of the switching rotating seat 803 drives the switching rotating plate 804 to rotate. The rotation of the switching rotating plate 804 drives the switching drive shaft 805 to rotate. The switching drive shaft 805 drives the inner sealing plate 801 to move. At the same time, the switching drive shaft 805 slides in the drive slide groove 811, and the inner sealing plate 801 slides horizontally in the limiting slide groove 802, thereby sealing the filter frame 5 at the corresponding position and preventing hot air from entering the power supply cabinet 1.
