Description
Technical Field
[0001] The utility model relates to the field of transformer switch accessories, and particularly to a waterproof cap for a transformer switch. Background Technique
[0002] Transformers are basic equipment for power transmission and distribution, and are widely used in industries, agriculture, transportation, urban communities and other fields. Generally, they are installed outdoors in large quantities. In the outdoor environment, if moisture enters the switch equipment, it will pose a serious safety hazard to the facilities and maintenance staff;
[0003] After retrieval, a Chinese patent discloses a waterproof cap for a transformer switch (publication number: CN 218769187U). In this patented technology, desiccants can be placed inside the dehumidification component. If moisture enters the inside of the waterproof cap, the desiccants can adsorb the entered moisture to prevent the moisture from affecting the use of the switch button. However, in the technical solution of the above patent document, when replacing silica gel and other desiccants, the round cover needs to be disassembled, and a large number of spherical or lime powder desiccants inside will directly fall out and scatter everywhere, forming a safety hazard.
[0004] Therefore, a waterproof cap for a transformer switch is proposed to solve the above problems. Content of the Utility Model
[0005] The purpose of the utility model is to provide a waterproof cap for a transformer switch to solve the above problems, and it improves the problem that when replacing silica gel and other desiccants, the round cover needs to be disassembled, and a large number of spherical or lime powder desiccants inside will directly fall out and scatter everywhere, forming a safety hazard.
[0006] The utility model realizes the above purpose through the following technical solutions. A waterproof cap for a transformer switch includes: a connecting pipe, the inner wall of the connecting pipe is magnetically connected with a waterproof cap, and the inner wall of the waterproof cap is threadedly connected with a mounting seat; a receiving mechanism for fixing the desiccant in the mounting seat is arranged on one side of the mounting seat; a pulling mechanism for quickly closing the receiving mechanism is arranged on one side of the mounting seat; wherein, the receiving mechanism includes an anti-disengagement component arranged on one side of the mounting seat, and a closing component is arranged on one side of the anti-disengagement component.
[0007] Preferably, the anti-disengagement component includes a placement pipe fixedly connected to the inner wall of the mounting seat, an upper cover is vertically slidably connected to the circumferential inner wall of the mounting seat, a plurality of springs are fixedly connected to the lower inner wall of the mounting seat, a blocking ring is slidably connected to the circumferential surface of the placement pipe, and the lower end of the blocking ring is fixedly connected to the plurality of springs. Through the anti-disengagement component, the desiccant in the mounting seat can be squeezed and collected, and it will not fall out when disassembled.
[0008] Preferably, the upper side of the blocking ring is in an arc shape that converges inward, and the bottom of the arc of the blocking ring is higher than the top of the placement tube. The arc shape of the blocking ring can push out the desiccant that enters the gap between the placement tube and the mounting seat, preventing excessive desiccant from entering and causing blockage and inability to install.
[0009] Preferably, a plurality of telescopic tubes are fixedly connected to the lower end of the blocking ring, and the lower ends of the plurality of telescopic tubes are fixedly connected to the lower inner wall of the mounting seat. A plurality of springs are respectively sleeved on the circumferential surfaces of the plurality of telescopic tubes. The telescopic tubes can support the plurality of springs to prevent the springs from bending laterally during compression and being elastically deformed and damaged.
[0010] Preferably, two sets of closing components are provided. Each set of closing components includes a rotating column rotatably connected to the upper end of the mounting seat. A blocking arc plate is fixedly connected to the circumferential surface of the rotating column, and a rotating rod is fixedly connected to the circumferential surface of the rotating column. The upper cover can be stably fixed by the closing components to prevent it from falling off.
[0011] Preferably, the side surface of the blocking arc plate is composed of two arcs. One of the arc surfaces of the blocking arc plate is relatively close to the inner circumferential wall of the waterproof cap. The arc of the blocking arc plate fits the arc of the waterproof cap, and at the same time, the blocking arc plate has a certain thickness. When the waterproof cap is installed on the mounting seat, the blocking arc plate will not shake inside the waterproof cap, preventing the blocking arc plate from rotating by itself and causing unstable connection. At the same time, the non-shaking fit of the blocking arc plate also prevents it from entering the internal thread groove of the waterproof cap and colliding and wearing each other.
[0012] Preferably, the lifting mechanism includes a mounting plate fixedly connected to the upper end of the upper cover. A rotating shaft is fixedly connected to the inner wall of the mounting plate, and a handle is rotatably connected to the surface of the rotating shaft. The upper cover can be conveniently lifted and disassembled by the handle, facilitating the replacement of the dryer inside the mounting seat.
[0013] Preferably, a placing block is fixedly connected to the lower inner wall of the mounting plate. The placing block is arranged below the handle. The placing block can support the handle to prevent the handle from fitting against the lower inner wall of the mounting plate and being unable to be grasped.
[0014] The beneficial effects of the present utility model are:
[0015] 1. When the staff replaces the desiccant in the mounting base, the waterproof cap can be pulled up to magnetically separate and fall off from the connecting pipe, and then the bottom of the mounting base is rotated to remove the mounting base. At this time, the desiccant is sealed in the mounting base and the storage mechanism and will not directly scatter. The fixing of the anti-detachment component by the sealing component is unlocked. At this time, the anti-detachment component can be disassembled. The anti-detachment component is disassembled and separated by the pulling mechanism. The desiccant is exposed but stored and will not directly fall out. At this time, the replacement is carried out. At this time, the desiccant in the anti-detachment component is sealed by the sealing component, the mounting base is installed by threads, and the waterproof cap is inserted into the connecting pipe for magnetic connection, thus completing the installation. During the installation and replacement, the desiccant will not scatter and fall out;
[0016] 2. Since the outer arc of the blocking arc plate fits well with the waterproof cap, it will not shake inside the waterproof cap, preventing the blocking arc plate from rotating by itself and causing unstable connection. At the same time, the non-shaking fit of the blocking arc plate also prevents it from entering the thread groove inside the waterproof cap and colliding and wearing each other.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Specifically implemented as: As Figures 1-4As shown in the figure, a waterproof cap for a transformer switch includes: a connecting pipe 1, an inner wall of the connecting pipe 1 is magnetically connected with a waterproof cap 2, and an inner wall of the waterproof cap 2 is threadedly connected with a mounting seat 3; a storage mechanism 4, which is arranged on one side of the mounting seat 3 and is used for fixing the desiccant in the mounting seat 3; a pulling-up mechanism 5, which is arranged on one side of the mounting seat 3 and is used for quickly pulling up the closure of the storage mechanism 4; wherein, the storage mechanism 4 includes a detachment prevention component 401 arranged on one side of the mounting seat 3, and a closure component 402 is arranged on one side of the detachment prevention component 401. When replacing the desiccant in the mounting seat 3 by this device, the waterproof cap 2 can be pulled up to be detached from the connecting pipe 1 at this time, and then the bottom of the mounting seat 3 is rotated. At this time, through threaded disassembly, the mounting seat 3 is taken out. At this time, the desiccant is sealed in the mounting seat 3 and the storage mechanism 4 and will not directly scatter. The fixation of the detachment prevention component 401 is unlocked through the closure component 402. At this time, the detachment prevention component 401 can be disassembled, and the detachment prevention component 401 is disassembled and separated through the pulling-up mechanism 5. The desiccant is exposed but stored and will not directly fall out. At this time, replacement is carried out. When the replacement is completed, the desiccant in the detachment prevention component 401 is sealed through the closure component 402, the mounting seat 3 is installed through threads, and the waterproof cap 2 is inserted into the connecting pipe 1 for magnetic connection, and the installation is completed. During installation and replacement, the desiccant will not scatter and fall out.
[0024] As Figure 3 and Figure 4As shown, the anti-disengagement component 401 includes a placement tube 4011 fixedly connected to the inner wall of the mounting base 3. The upper cover 4015 is vertically slidably connected to the circumferential inner wall of the mounting base 3. A plurality of springs 4013 are fixedly connected to the lower inner wall of the mounting base 3. A blocking ring 4012 is slidably connected to the circumferential surface of the placement tube 4011. The lower end of the blocking ring 4012 is fixedly connected to the plurality of springs 4013. When storing the desiccant, the desiccant can be placed into the inner wall of the placement tube 4011, and then pressed down by the upper cover 4015 to enter the gap between the placement tube 4011 and the mounting base 3, closing the upper side of the placement tube 4011. At this time, the desiccant in the placement tube 4011 is sealed and will not fall out randomly even if the mounting base 3 is disassembled. The spring 4013 pushes the blocking ring 4012 to prevent the desiccant from entering the gap between the placement tube 4011 and the mounting base 3 for protection, preventing blockage and making it impossible to install the upper cover 4015 to the corresponding position. The height of the upper cover 4015 is less than the height of the inner wall of the mounting base 3. When the installation is completed and the spring 4013 and the telescopic tube 4014 are compressed, the height is flush with the height of the inner wall of the mounting base 3. The upper side of the blocking ring 4012 is in an inwardly converging arc shape, and the bottom of the arc of the blocking ring 4012 is higher than the top height of the placement tube 4011. The arc shape of the blocking ring 4012 can push out the desiccant that enters the gap between the placement tube 4011 and the mounting base 3 through the inclined plane of the arc, preventing the desiccant from entering the gap between the placement tube 4011 and the mounting base 3. The lower end of the blocking ring 4012 is fixedly connected to a plurality of telescopic tubes 4014, and the lower ends of the plurality of telescopic tubes 4014 are fixedly connected to the lower inner wall of the mounting base 3. The plurality of springs 4013 are respectively sleeved on the circumferential surfaces of the plurality of telescopic tubes 4014. When the upper cover 4015 is installed and compresses the plurality of springs 4013, the spring 4013 is prone to lateral elastic deformation and damage. At this time, the telescopic tube 4014 supports the spring 4013, making the spring 4013 not prone to lateral elastic deformation.
[0025] As Figure 3 and Figure 4As shown in the figure, there are two sets of closed components 402. Each set of closed components 402 includes a rotating column 4021 rotatably connected to the upper end of the mounting base 3. A blocking arc plate 4022 is fixedly connected to the circumferential surface of the rotating column 4021, and a rotating rod 4023 is fixedly connected to the circumferential surface of the rotating column 4021. After the upper cover 4015 is installed, at this time, by rotating the rotating rod 4023, the rotating rod 4023 drives the rotating column 4021 and the blocking arc plate 4022 to rotate. The blocking arc plate 4022 blocks the upper side of the upper cover 4015 to prevent the upper cover 4015 from rising and detaching. When disassembling, rotate the rotating rod 4023 again. The installation position of the rotating column 4021 is close to the circumferential surface of the mounting base 3. When the blocking arc plate 4022 rotates to the other side, the blocking arc plate 4022 no longer contacts the upper side of the upper cover 4015. The side surface of the blocking arc plate 4022 is composed of two arcs. One side arc surface of the blocking arc plate 4022 is relatively fitted to the inner circumferential wall of the waterproof cap 2. The blocking arc plate 4022 is fitted to the arc of the waterproof cap 2. At the same time, the blocking arc plate 4022 has a certain thickness, so that when the waterproof cap 2 and the mounting base 3 are installed, the blocking arc plate 4022 will not shake inside the waterproof cap 2, preventing the blocking arc plate 4022 from rotating by itself and causing unstable connection. At the same time, the fitting and non-shaking of the blocking arc plate 4022 also prevent it from entering the internal thread groove of the waterproof cap 2 and colliding and wearing each other. The pulling-up mechanism 5 includes a mounting disc 501 fixedly connected to the upper end of the upper cover 4015. A rotating shaft 502 is fixedly connected to the inner wall of the mounting disc 501. A handle 503 is rotatably connected to the surface of the rotating shaft 502. When the mounting base 3 is disassembled and the closed component 402 is unlocked, at this time, the handle 503 can be pulled to conveniently disassemble and lift the upper cover 4015. At this time, the desiccant in the placing tube 4011 can be poured out to the storage position for replacement. A placing block 504 is fixedly connected to the lower inner wall of the mounting disc 501. The placing block 504 is arranged below the handle 503. The handle 503 can be supported by the placing block 504 to prevent the handle 503 from fitting to the lower inner wall of the mounting disc 501 and being unable to be grasped.
[0026] When the utility model is in use and the desiccant in the mounting base 3 is replaced through this device, the waterproof cap 2 can be pulled up at this time to be detached from the connecting pipe 1, and then the bottom of the mounting base 3 is rotated. At this time, through threaded disassembly, the mounting base 3 is taken out. At this time, the desiccant is sealed in the placing pipe 4011 and is blocked and closed by the upper cover 4015 and will not fall out and scatter. At this time, the mounting base 3 is taken to the replacement operation position, and the rotating rod 4023 is rotated. The rotating rod 4023 drives the rotating column 4021 and the blocking arc plate 4022 to rotate. The blocking arc plate 4022 no longer contacts the upper side of the upper cover 4015, and the spring 4013 pushes the upper cover 4015 to rise. At this time, by pulling the handle 503, the upper cover 4015 can be lifted out. At this time, the desiccant is exposed but is stored in the placing pipe 4011. The inner wall height of the mounting base 3 is much greater than the height of the placing pipe 4011. The desiccant in the placing pipe 4011 is blocked by the inclined plane of the blocking ring 4012 and gathers and will not scatter, and can be replaced. After the replacement is completed, the upper cover 4015 is placed into the mounting base 3, and the rotating rod 4023 is rotated. The rotating rod 4023 drives the rotating column 4021 and the blocking arc plate 4022 to rotate. The blocking arc plate 4022 blocks the upper side of the upper cover 4015 to prevent the upper cover 4015 from rising and detaching. Then the mounting base 3 is installed by threading. At this time, the replacement of the desiccant in the mounting base 3 is completed, and during the replacement process, the desiccant will not suddenly scatter and fall out.
[0027] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
