Description

Technical Field

[0001] This invention relates to the field of prefabricated substation technology, specifically a dehumidification device for prefabricated substations. Background Technology

[0002] A prefabricated substation, also known as a prefabricated transformer substation, is a factory-prefabricated, compact indoor / outdoor power distribution system that integrates high-voltage switchgear, distribution transformers, and low-voltage distribution equipment according to a specific wiring scheme. Prefabricated substations are suitable for mines, factories, oil and gas fields, and wind power stations, replacing traditional civil engineering substations and becoming a new type of complete power distribution system. However, current prefabricated substations lack dehumidification and drying mechanisms. When ventilating the substation, humid outside air enters, causing condensation inside the enclosure. When this condensation drips onto the electrical equipment inside, it can trigger tripping or other equipment malfunctions, thus affecting the equipment's lifespan.

[0003] Chinese patent CN219350991U discloses a box-type substation with dehumidification and drying functions, including a substation body. A drying box is fixedly installed at the bottom of the dehumidification box, and a second protective net is provided on the drying box. Through the design of the drying box, discharge cylinder, and collection cylinder, the desiccant in the drying box can dehumidify and dry the moisture in the air, preventing moisture from entering the box-type substation. The air dried by the desiccant can pass through the second protective net and be discharged into the substation body. After the desiccant has been used for a long time, the desiccant in the drying box can be discharged into the collection cylinder through the second discharge pipe, the second solenoid valve and the collection cylinder. The desiccant stored in the discharge cylinder can be discharged into the drying box through the discharge cylinder, the first discharge pipe and the first solenoid valve, so that the desiccant in the drying box can be replaced, thereby improving the dehumidification and drying effect of the air.

[0004] The above-mentioned technical solution has some drawbacks in use. For example, in actual use, users cannot know the specific usage status of the desiccant particles inside the drying box. The replacement of desiccant particles is often based on usage time, which leads to the desiccant particles being replaced before reaching their service life, resulting in resource waste. Furthermore, since the desiccant particles are fixedly placed inside the drying box, the desiccant particles at the top of the drying box absorb much more moisture than those at the bottom, resulting in a significant difference in the service life of the desiccant particles inside the drying box. This affects the absorption of moisture and also causes the desiccant particles at the bottom of the drying box to be replaced before they are fully utilized, leading to further resource waste. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides a dehumidification device for prefabricated substations, which solves the above-mentioned problems.

At this time, the conical mesh moves down along the surface of the feed pipe and drives the stirring member to move down synchronously. When the conical mesh moves down, the desiccant particles in the conical mesh can be discharged through the feed pipe. After the agitator moves down, the reset device operates, thereby pushing the conical mesh upward.

[0015] Preferably, a dust filter is provided on the inner side of the outer end of the ventilation duct, and the end of the ventilation duct near the fan passes through the housing and extends out of the housing.

[0016] Compared with the prior art, the present invention provides a dehumidification device for prefabricated substations, which has the following beneficial effects: 1. In this invention, when the fiber desiccant particles inside the conical mesh reach adsorption saturation, the weight of the conical mesh increases significantly. At this point, the weight of the conical mesh exceeds the locking force of the locking element, causing the locking element to release its hold on the conical mesh. The conical mesh then carries the desiccant particles downwards along the feed pipe. During this downward movement, the desiccant particles inside the conical mesh are discharged through the feed pipe. As the conical mesh gradually descends, the adsorption-saturated desiccant particles inside are gradually discharged, and the weight of the conical mesh decreases. Finally, as the conical mesh descends to its maximum weight... After positioning, the reset mechanism operates, lifting the conical mesh and pushing it upwards. The reset mechanism then pushes the conical mesh to the locking mechanism's position, whereupon the locking mechanism locks the mesh again. The feeding mechanism then adds new desiccant particles into the conical mesh, achieving automatic discharge after the desiccant particles reach adsorption saturation. Furthermore, it automatically adds new desiccant particles after discharge, greatly improving ease of use and practicality.

[0017] 2. In this invention, when the fan is running, the fan drives the agitator to operate, which agitates the desiccant particles inside the conical mesh. This allows the desiccant particles inside the conical mesh to fully absorb moisture from the air, thereby improving the effectiveness of the desiccant particles. Furthermore, as the conical mesh moves downward, the agitator moves downward synchronously with the conical mesh. At this time, the agitation of the conical mesh by the agitator allows the desiccant particles inside the conical mesh to be quickly and completely discharged from the conical mesh, thereby improving the efficiency and effectiveness of desiccant particle discharge and further enhancing practicality.

[0018] 3. In this invention, when the conical mesh moves downward, it squeezes the buffer spring at its bottom, which slows down the downward movement of the conical mesh. This prolongs the time for the desiccant particles inside the conical mesh to be discharged, thus helping to completely discharge the desiccant particles and further improving the discharge effect. On the other hand, when the reset member drives the conical mesh to move upward, it can also provide a certain thrust, thereby improving practicality. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a dehumidification device for prefabricated substations.

[0023] Example 1: Please refer to Figures 1-12 A dehumidification device for a prefabricated substation includes a box body 1, a ventilation pipe 2 inside the box body 1, and a fan 3, an agitator 4, a conical mesh 5, a locking element 8, a resetting element 6 and a feeding pipe 7 arranged sequentially from top to bottom inside the ventilation pipe 2. A feeding mechanism 9 is arranged on the outside of the ventilation pipe 2. The fan 3 is used to blow air into the ventilation pipe 2, the agitator 4 is used to agitate the desiccant particles in the conical mesh 5, the locking device 8 is used to lock the conical mesh 5, the resetting device 6 is used to lift the conical mesh 5 after it has moved down, the feeding pipe 7 is used to feed the desiccant particles in the conical mesh 5, and the feeding mechanism 9 is used to feed the desiccant particles into the conical mesh 5. When the desiccant particles in the conical mesh 5 reach the adsorption saturation threshold, the locking element 8 can unlock the position of the conical mesh 5. At this time, the conical mesh 5 moves down along the surface of the feed pipe 7 and drives the stirring element 4 to move down synchronously. When the conical mesh 5 moves down, the desiccant particles in the conical mesh 5 can be discharged through the feed pipe 7. After the agitator 4 moves down, the resetter 6 operates, thereby pushing the conical mesh 5 upward. When the conical mesh 5 moves up to contact the locking member 8, the locking member 8 locks the conical mesh 5. At the same time, the feeding mechanism 9 adds new desiccant particles into the conical mesh 5.

[0024] Initially, the locking element 8 locks the conical mesh 5. When the fan 3 operates, it drives the agitator 4 to agitate the desiccant inside the conical mesh 5. When the desiccant particles inside the conical mesh 5 reach adsorption saturation, the weight of the desiccant particles increases significantly, further increasing the gravity of the conical mesh 5. At this point, the weight of the conical mesh 5 exceeds the locking force of the locking element 8, causing the conical mesh 5 to move downwards along the feed pipe 7. As the conical mesh 5 moves downwards, the desiccant particles inside it are discharged through the feed pipe 7. The agitator 4 moves downwards synchronously with the conical mesh 5, agitating the interior of the conical mesh 5 during its downward movement. This allows the desiccant particles inside the conical mesh 5 to be quickly and completely discharged from the conical mesh 5. After being moved to the maximum position, the reset component 6 operates, lifting the conical mesh 5 and driving it upward. Once the conical mesh 5 reaches the position of the locking component 8, the locking component 8 locks the conical mesh 5 again. Then, the feeding mechanism 9 operates, adding new desiccant particles into the conical mesh 5. This allows for automatic replacement of the desiccant particles when they reach adsorption saturation, and also automatic addition of new desiccant particles. Simultaneously, the agitator 4 agitates the desiccant particles within the conical mesh 5, improving the adsorption effect while preventing significant differences in the lifespan of the desiccant particles. Furthermore, the agitator 4 improves the feeding efficiency and discharge effect of the desiccant particles during feeding.

[0025] Example 2: See Figures 1-12 Unlike the first embodiment described above, the agitator 4 includes a turbine fan 41, which is disposed inside the ventilation pipe 2 and distributed above the conical mesh 5. A key shaft 42 is fixedly connected to the bottom of the turbine fan 41. The end of the key shaft 42 away from the turbine fan 41 is rotatably connected to the top surface of the feed pipe 7. A ring 43 is keyed onto the key shaft 42. A stirring rod 44 is arranged in a circular array at the bottom of the ring 43. The end of the stirring rod 44 away from the ring 43 abuts against the inner side of the conical mesh 5. The fan 3 is installed inside one end of the ventilation pipe 2, and two sets of fans 3 are provided. A dust filter is provided inside the outer end of the ventilation pipe 2. The end of the ventilation pipe 2 near the fan 3 passes through the housing 1 and extends out of the housing 1. During ventilation, fan 3 operates, blowing air into ventilation duct 2. The air passes through turbo fan 41, causing it to rotate. The rotation of turbo fan 41 drives key shaft 42 to rotate, which in turn drives ring 43 to rotate. The rotation of ring 43 drives stirring rod 44 to rotate, which in turn stirs the desiccant particles in conical mesh 5. This allows the desiccant particles to absorb moisture from the air evenly. As conical mesh 5 moves downward, ring 43 and stirring rod 44 move downward and rotate along key shaft 42. This ensures that even when conical mesh 5 is discharging material, stirring rod 44 continues to stir the conical mesh 5, greatly improving its practicality.

[0026] Example 3, see Figures 1-12Unlike Embodiment 2 described above, the reset component 6 includes a wedge-shaped block 61. The wedge-shaped block 61 is distributed inside the ventilation pipe 2. Several vertically arranged rolling balls 62 are provided on the wedge-shaped block 61. When the ring 43 moves upward, it can drive the wedge-shaped block 61 to move outward from the ventilation pipe 2. A limiting rod 63 is fixedly connected to the side of the wedge-shaped block 61 away from the rolling balls 62. The limiting rod 63 passes through the ventilation pipe 2 and extends to the outside of the ventilation pipe 2. A reset spring 64 is fixedly connected to the limiting rod 63. The end of the reset spring 64 away from the limiting rod 63 is fixedly connected to the outside of the ventilation pipe 2. The limiting rod 63 is distributed on the wedge-shaped block 61. On the upper and lower sides of block 61, the reset component 6 also includes a connecting rod 65 and a bottom filter 66. The bottom filter 66 is fixedly connected to the inside of the ventilation pipe 2, and the feed pipe 7 is fixedly connected to the bottom filter 66. Several feed ports 71 are opened around the circumference of the surface of the feed pipe 7. The bottom of the feed pipe 7 has an outer receiving box (not shown). One end of the connecting rod 65 passes through the ventilation pipe 2 and is fixedly connected to the wedge block 61. The other end of the connecting rod 65 passes through the ventilation pipe 2 and is fixedly connected to a C-shaped rod 67. The end of the C-shaped rod 67 away from the connecting rod 65 is fixedly connected to a lower slider 68. The inner side of the lower slider 68 is slidably connected to a lower fixing rod 69. A fixed rod 69 is fixedly connected to the bottom filter screen 66. A scissor bar 610 is rotatably connected to the inner side of the lower slider 68. An upper slider 611 is rotatably connected to the end of the scissor bar 610 away from the lower slider 68. An upper fixed rod 612 is slidably connected to the inner side of the upper slider 611. A top plate 613 is fixedly connected to the outer side of the upper fixed rod 612. Guide rods 614 are symmetrically arranged on the top of the top plate 613. The two ends of the scissor bar 610 away from the upper slider 611 and the lower slider 68 are rotatably connected to the top plate 613 and the bottom filter screen 66, respectively. When the top plate 613 moves upward, the guide rods 614 can lift the conical mesh 5. The locking component 8 includes an inner groove 81, which is circumferentially opened on the inner side of the ventilation pipe 2. A locking spring 82 is fixedly connected to the inner side of the inner groove 81. A round-headed rod 83 is fixedly connected to the end of the locking spring 82 away from the inner groove 81. A round-headed slot 84 is inserted into the end of the round-headed rod 83 away from the locking spring 82. The round-headed slot 84 is circumferentially opened on the outer side of the conical mesh 5. A buffer spring 51 is fixedly connected to the bottom of the conical mesh 5. A fixing ring is fixedly connected to the end of the buffer spring 51 away from the conical mesh 5. The fixing ring is fixedly connected to the feed pipe 7. A circular hole with a diameter larger than the fixing ring is opened on the top plate 613. In the initial state, the round-headed rod 83 in the inner groove 81 is inserted into the round-headed slot 84 and, with the cooperation of the locking spring 82, locks the conical mesh 5. At the same time, the ring 43 on the agitator 4 abuts against the rolling ball 62 on the wedge block 61. At this time, the wedge block 61 is squeezed by the ring 43, thus contacting the inner wall of the ventilation pipe 2. At this time, the limiting rod 63 on the outside of the wedge block 61 stretches the return spring 64, and under the action of the ring 43, the elastic potential energy of the return spring 64 is stored. As the desiccant particles in the conical mesh 5 absorb more and more moisture, the weight of the desiccant particles will increase greatly. At this time, the weight of the conical mesh 5 is greater than that of the locking spring 82 and the round-headed rod 83 in the round-headed slot 84. The locking force of slot 84 and conical mesh 5 causes the round head slot 84 on conical mesh 5 to separate from the round head rod 83. Simultaneously, conical mesh 5 moves downward along the feed pipe 7 under gravity. During this downward movement, the buffer spring 51 is compressed, slowing down the downward speed of conical mesh 5 and extending the discharge time of desiccant particles. As conical mesh 5 moves downward, the discharge port 71 on the feed pipe 7 gradually connects with conical mesh 5. At this point, the desiccant particles inside conical mesh 5 are discharged through the discharge port 71 and rapidly discharged under the action of the agitator 4. As conical mesh 5 moves downward, the ring 43 on the agitator 4 moves downward synchronously, gradually separating from the wedge block 61. When the ring 43 is completely separated from the wedge block 61, the conical mesh 5 completes the discharge of desiccant particles. After the wedge block 61 loses the pressure of the ring 43, the elastic potential energy of the return spring 64 is released. At this time, the return spring 64 drives the wedge block 61 and the limiting rod 63 to move into the ventilation pipe 2. The movement of the wedge block 61 drives the connecting rod 65 to move. The movement of the connecting rod 65 drives the C-shaped rod 67 and the lower slider 68 to move along the lower fixed rod 69. Simultaneously, the upper slider 611 moves along the upper fixed rod 612. At this time, the scissor rod 610 deforms. The deformation of the scissor rod 610 drives the top plate 613 to move upward. The upward movement of the top plate 613 drives the guide rod 614 to move upward. The upward movement of the guide rod 614... During the process, it comes into contact with the conical mesh 5 and drives the conical mesh 5 to move upward. At this time, due to the discharge of desiccant particles inside the conical mesh 5, the weight of the conical mesh 5 decreases. At this time, the buffer spring 51 also gradually drives the conical mesh 5 to move upward slowly. The movement of the conical mesh 5 drives the ring 43 to move upward. The upward movement of the ring 43 squeezes the wedge block 61, thereby gradually driving the wedge block 61 to move to the outside of the ventilation pipe 2. Then the ring 43 squeezes the wedge block 61 again until it contacts the inner wall of the ventilation pipe 2. At this time, the conical mesh 5 moves to the position of the locking part 8 through the cooperation of the guide rod 614 and the buffer spring 51. At this time, the round head rod 83 is inserted into the round head slot 84 again, thereby completing the locking of the conical mesh 5.

[0027] It should be noted that the spring force of the return spring 64 is greater than that of the buffer spring 51 and the locking spring 82.

[0028] Example 4, see Figures 1-12Unlike Embodiment 3 described above, the feeding mechanism 9 includes an arc groove 91, which is formed on the ventilation pipe 2. An arc block 92 is slidably connected to the inner side of the arc groove 91. Corrugated rubber plates 93 are fixedly connected to both the upper and lower ends of the arc block 92. The end of the corrugated rubber plate 93 away from the arc block 92 is fixedly connected to the inner side of the arc groove 91. A bent rod 94 is fixedly connected to the inner side of the arc block 92. The end of the bent rod 94 away from the arc block 92 is fixedly connected to the conical mesh 5. The feeding mechanism 9 also includes an outer rod 95 and a feeding cylinder 96. One end of the outer rod 95 is fixedly connected to the outer side of the arc block 92, and the other end of the outer rod 95 away from the arc block 92 is fixedly connected to the conical mesh 5. A conical block 97 is fixedly connected to one end of the arc-shaped block 92 through the feeding cylinder 96. A conical plate 98 is inserted into the outside of the conical block 97. A discharge hole is opened on the conical plate 98. The conical block 97 is inserted into the discharge hole. The conical plate 98 is fixedly connected to the inside of the feeding cylinder 96. A shell 99 is fixedly connected to the outside of the feeding cylinder 96. The shell 99 is fixedly connected to the inside of the box 1. A feeding pipe 910 is fixedly connected to the bottom of the feeding cylinder 96. The end of the feeding pipe 910 away from the feeding cylinder 96 is connected to the ventilation pipe 2. The feeding pipe 910 is distributed above the conical mesh 5. A feeding pipe (not shown) is also provided at the top of the feeding cylinder 96. In use, new desiccant granules are added to the feeding cylinder 96 through the feeding pipe on the feeding cylinder 96. Since the conical block 97 seals the conical plate 98 at this time, the desiccant granules are retained on the conical plate 98. When the conical mesh 5 moves downward, the bent rod 94 moves downward simultaneously. The downward movement of the bent rod 94 causes the arc block 92 to move downward, stretching the corrugated rubber plate 93 and causing the outer rod 95 to move downward. The downward movement of the outer rod 95 causes the conical block 97 to move downward. After moving downward, the conical block 97 separates from the conical plate 98, and as the conical mesh 5 moves downward, the conical block 97 aligns with the upper... When the feed pipe 910 is closed, the desiccant particles on the conical plate 98 fall through the discharge hole on the conical plate 98. At this time, the desiccant particles gather at the feed pipe 910. When the conical mesh 5 moves upward, similarly, the bent rod 94, the arc block 92 and the outer rod 95 move upward. The upward movement of the outer rod 95 causes the conical block 97 to separate from the feed pipe 910 and move again to insert with the conical plate 98. At this time, the feed pipe 910 is opened, and the desiccant particles at the feed pipe 910 enter the conical mesh 5 through the feed pipe 910, thus completing the feeding of desiccant particles.

[0029] It should be noted that the bottom of the outer casing 99 is open. The air blown out by the fan 3 passes through the agitator 4 and the conical screen 5 and is discharged through the bottom filter screen 66. After that, the air is discharged into the box 1 through the bottom of the outer casing 99.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
