Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of transformers, and in particular to a transformer and a high-voltage electrode boiler. Background Art
[0002] The high-voltage electrode boiler uses the conductivity and resistance characteristics of water to transport current and generate steam. The greater the flowing current (ampere), the more steam is generated. Since heat is generated in water and quickly absorbed by the water itself, and there is no heat loss caused by the chimney, the electrode boiler can convert almost 100% of electrical energy into thermal energy, with extremely high efficiency. Among them, the high-voltage electrode boiler will use a transformer for power supply operation when in use. The relevant prior art of transformers is disclosed in the Chinese patent library. For example, the announcement number CN111243829B discloses a transformer, including a transformer body, a base, an inner support plate, a telescopic column, a bonding plate, a stabilizing mechanism and a clamping mechanism. A group of U-shaped heat dissipation pipes are arranged on the left and right sides of the transformer body. The heat dissipation pipes are evenly distributed from front to back in a grid shape. A connecting pipe is arranged in the middle of each group of heat dissipation pipes. A channel steel is arranged at both the front and rear ends of the bottom of the transformer body. The channel steel is connected to the base. An inner support plate is distributed on the inner side of the middle of each group of heat dissipation pipes. The invention can solve the problems existing in the installation of power transformers locked between utility poles: the locking frame of the power transformer cannot lock the transformer for utility poles with different spacings, which makes the use range of the locking frame small, and the installation operation of the locking frame is complicated.
[0003] For another example, announcement number CN114050039B discloses an anti-theft transformer, including columns, a steel frame fixedly connected between the columns, and an induction box fixedly provided on the upper end surface of the steel frame; the invention uses the cooperation of the alarm motor and the sound and light alarm assembly to emit bright lights and piercing alarm sounds when the offender attempts to steal the transformer, thereby warning the offender and stopping the illegal behavior in time to prevent excessive damage to the transformer-related equipment; using the counter motor and camera, when the offender ignores the sound and light warnings and attempts to steal the transformer violently, the visual image of the offender is recorded in time to prevent damage to the camera device; at the same time, the shooting device does not need to be connected to the power supply when it is on standby, thus saving energy; and using the cooperation of the buffer block and the buffer rod, when facing strong winds or other severe vibrations, the external force source can be sensitively captured to avoid the incorrect activation of the anti-theft device, which would cause excessive use of the equipment and save costs.

Thus, the phrases "one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. appearing in different places in this specification do not necessarily all refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways. Example 1
[0031] This embodiment provides a transformer, referring to Figure 1 , which shows a schematic diagram of the installation structure of the transformer. It can be seen from the figure that the transformer includes a transformer body 1. The transformer body 1 directly adopts an existing transformer that can be purchased on the market, for example, the model can be S13-M; the bottom of the transformer body 1 is fixedly installed (for example, by bolts, etc.) with a base frame 2, and the other side of the base frame 2 is used for fixed connection with the outer wall of the boiler furnace body 15; an annular track 3 is provided above the transformer body 1, and a limited slot 4 is formed on the outer wall of the annular track 3. A sliding arm 5 is slidably connected in the limited slot 4, and the moving trajectory of the sliding arm 5 is parallel to the cross-sectional plane of the annular track 3; a hanging arm 5 is fixedly connected to the free end of the sliding arm 5. Plate 6, four sponge stickers 7 are fixedly connected to the bottom of the hanging plate 6 by glue; of course, the number of sponge stickers 7 is not limited to four, and the four sponge stickers 7 are arranged and extended in a linear array. When the sliding arm 5 moves, the four sponge stickers 7 are used to clean the dust deposited on the top of the transformer body 1; a driving mechanism is installed on the annular track 3, and the driving mechanism is used to drive the sliding arm 5 to reciprocate on the limit slot 4, and the driving mechanism is used to be fixedly connected to the outer wall of the boiler furnace body 15; at the same time, it is defined that: when the sliding arm 5 moves back and forth, the sponge stickers 7 reciprocately wipe the top of the transformer body 1; the specific structure of the driving mechanism is as follows.
[0032] In the first mode, the driving mechanism directly uses an electric telescopic rod available on the market, the telescopic shaft of the electric telescopic rod is fixedly connected to the sliding arm 5, and the outer cylinder wall of the electric telescopic rod is used to be fixedly connected to the outer wall of the boiler furnace body 15. The driving mechanism of the first mode is not shown in the figure. When the driving mechanism is in use, the telescopic shaft of the electric telescopic rod reciprocates, thereby indirectly driving the sliding arm 5 to reciprocate.
[0033] Method 2, reference Figure 2 , Figure 2 What is shown is a schematic diagram of the installation structure of the driving mechanism of the second mode from the first perspective. It can be seen from the figure that the driving mechanism includes a turntable 8, and the outer edge of the turntable 8 is connected to the inner ring track of the annular track 3 in a sliding and clamping manner; a toggle seat 9 is fixedly connected to the eccentric part of the top of the turntable 8, and a limiting guide groove 10 is fixedly connected (for example, welded) on one end of the sliding arm 5 adjacent to the toggle seat 9, and the toggle seat 9 forms a sliding connection with the inner slideway of the limiting guide groove 10; at the same time, it is stipulated that: whenever the turntable 8 rotates one circle along the inner ring track of the annular track 3 in an orbital manner, the toggle seat 9 drags the limiting guide groove 10 to move first from one side of the annular track 3 to the opposite side of the annular track 3, and then moves from the opposite side of the annular track 3 to the starting position of the annular track 3; refer to Figure 3 , Figure 3 What is shown is a schematic diagram of the installation structure of the second mode driving mechanism from a second perspective. It can be seen from the figure that the driving mechanism also includes an eccentric arm 11. The first end of the eccentric arm 11 is fixedly connected to the central axis 12, and the central axis 12 is arranged concentrically with the center of the circular track 3; the other end of the central axis 12 is fixedly connected to the outer end edge of the load-bearing arm 13, and the free part of the load-bearing arm 13 is used to connect to the outer wall of the boiler furnace body 15; the second end of the eccentric arm 11 is rotatably connected to the protrusion at the bottom center of the turntable 8; the load-bearing arm 13 is installed with a first driving source (the first driving source can directly use an existing servo motor, which will not be repeated here), and the first driving source is used to drive the eccentric arm 11 to rotate.
[0034] As a further optimization of the driving mechanism of the second mode, an impeller 14 is sleeved on the protrusion at the bottom center of the turntable 8, and a circle of internal teeth is fixedly connected to the inner ring of the annular track 3; a circle of external teeth is formed on the outer wall of the turntable 8, and the internal teeth are meshed and connected with the external teeth and are linked; the internal teeth and the external teeth are not shown in the figure, and the teeth are all of common shapes, which will not be repeated here. Due to the mutual meshing and cooperation between the internal teeth and the external teeth, when the turntable 8 revolves along the annular track 3, the turntable 8 and the impeller 14 will also rotate accordingly; thus, when the sponge patch 7 wipes the transformer body 1, the impeller 14 can be linked to revolve and rotate accordingly; finally, it is possible to achieve dust removal treatment for the transformer body 1, and also to achieve all-round cooling treatment for the transformer body 1.
[0035] The transformer principle after adopting the second driving mechanism is as follows: Figure 2 , Figure 3 First, the rotation of the eccentric arm 11 is realized by starting the first driving source. The rotating eccentric arm 11 drives the turntable 8 to perform circular motion along the inner ring of the annular track 3 (that is, the turntable 8 revolves around the central axis 12 along the a direction); then, the turntable 8 revolving around the central axis 12 correspondingly drives the toggle seat 9 to rotate. Due to the common limitation of the limit slot 4 and the limit guide groove 10, the moving toggle seat 9 drags the limit guide groove 10 to move along the b1 or b2 direction, prompting the sliding arm 5 and the sponge sticker 7 on the sliding arm 5 to reciprocate, thereby ensuring that the sponge sticker 7 completely cleans the dust on the transformer body 1 during the reciprocating movement; at the same time, when the turntable 8 revolves, due to the mutual friction between the turntable 8 and the annular track 3 or the mutual meshing of the internal teeth and the external teeth, the turntable 8 will also rotate, driving the impeller 14 to revolve and rotate, thereby achieving a sufficient heat dissipation effect on the transformer.
[0036] The present invention combines the sliding arm 5, the sponge patch 7 and the driving mechanism to ensure that the transformer can be cleaned in time after dust is deposited. Compared with the prior art, the present invention solves the problem that the transformer of the existing high-voltage electrode boiler lacks a cleaning device; on the other hand, the present invention combines the internal teeth, the external teeth and the fan wheel 14 to solve the problem of heat dissipation of the transformer. Example 2
[0037] This embodiment provides a high voltage electrode boiler, referring to Figure 4 , which is a schematic diagram of the three-dimensional structure of a high-voltage electrode boiler. It can be seen from the figure that the high-voltage electrode boiler includes the transformer in Example 1, which is installed on the boiler furnace body 15; further combined Figure 5The cross-sectional view of the boiler furnace body 15 shown in FIG. 1 is a cross-sectional view of the boiler furnace body 15, wherein the high-voltage electrode type boiler further comprises an insulating inner cylinder 16, which is concentrically arranged above the boiler furnace body 15, and the insulating inner cylinder 16 is connected to the boiler furnace body 15 through an insulator; the insulating inner cylinder 16 is provided with three electrodes 17 in a circular array, and the three electrodes 17 together constitute a three-phase electrode 17; a single electrode 17 (such as Figure 6 The lower end ring portion of the single electrode 17 (shown in the three-dimensional structural schematic diagram of the single electrode 17) is formed with ten branch heads 18 in an annular array. In actual design, the number of branch heads 18 is not limited to ten; the top of the single electrode 17 is formed with two cable connection columns 19, the column body of the cable connection column 19 is fixedly connected to the insulating port at the top of the boiler furnace body 15, and the top of the cable connection column 19 is formed with a high-voltage cable connector 20, which is used to connect to the wiring point on the transformer; the top of the boiler furnace body 15 is formed with a steam outlet 21 in an integrated manner, and the bottom of the boiler furnace body 15 is formed with a steam outlet 21 in an integrated manner. A water inlet pipe 22 is formed in a type manner, and the free end of the water inlet pipe 22 is used to communicate with the water reservoir, and the water in the water reservoir is pumped into the boiler furnace body 15 through the water supply pump (the water reservoir and the water supply pump can directly use existing products, which are not shown in the figure); an internal circulation pump 23 is arranged on the bottom side of the inner part of the boiler furnace body 15, and the water outlet end of the internal circulation pump 23 is connected to a three-way valve 24, and the three outlets of the three-way valve 24 are respectively connected to water injection pipes 25, which pass through the insulating inner cylinder 16 and are placed under the corresponding single electrode 17, and the three-way valve 24 is connected to an electric heater for heating the water flowing through the three-way valve 24.
[0038] The general working principle of the high-voltage electrode boiler is as follows: First, when in use, the transformer in Example 1 is started, so that the transformer supplies power to the three-phase electrode 17. At the same time, the water supply pump needs to be started to inject water into the boiler furnace body 15 through the water inlet pipe 22, and the water in the boiler furnace body 15 is sequentially transported to the three-way valve 24 and the water injection pipe 25 through the internal circulation pump 23. Because the electric heater continuously heats the water flowing through the three-way valve 24, it is ensured that the water sprayed to the electrode 17 by the water injection pipe 25 is high-temperature hot water. Then, the high-temperature hot water jet hits the corresponding electrode 17, thereby creating a current path, and the high-temperature hot water generates heat and steam through this path, and the steam flows out from the steam outlet 21 and flows into the corresponding guide pipe.
[0039] During the use of the electrode 17, high temperature hot water is required to contact the electrode 17. When the electrode 17 contacts the high temperature hot water, scaling may occur on the surface of the electrode 17. After scaling of the electrode 17, the contact area between the electrode 17 and the high temperature hot water may be reduced, thereby affecting the heating efficiency of the electrode 17. For this reason, the present invention further designs a descaling mechanism, referring to Figure 7, which is a schematic diagram of the installation structure of the descaling mechanism. It can be seen from the figure that the descaling mechanism is connected to the electrode 17, and the descaling mechanism is used to clean the scale on the electrode 17; the specific structure of the descaling mechanism is as follows.
[0040] Combination Figure 7-8 ,in, Figure 8 What is shown is a schematic diagram of the three-dimensional structure of the descaling mechanism. It can be seen from the above two figures that the descaling mechanism includes a main shaft 26, which is rotatably connected to the top center of the boiler furnace body 15 in a concentric manner. There are three lifting scrapers 27 in a circular array around the main shaft 26. Ten circular holes 28 are provided at equal angles on the edge of a single lifting scraper 27, and the ten circular holes 28 correspond to the ten branch heads 18 on the corresponding electrode 17 one by one and form a sliding connection; a threaded hole is provided in the center of the lifting scraper 27, and a screw 29 is connected to the threaded hole in a threaded manner, and the screw 29 is rotatably connected to the top of the boiler furnace body 15; a roller 30 is concentrically fixedly connected to the rod body of each screw 29, and a belt 31 is transmission-connected to the roller 30, and the other end of the belt 31 forms a transmission connection with the transmission part on the bottom side of the main shaft 26; a second driving source is transmission-connected to the main shaft 26, and the second driving source is used to drive the main shaft 26 to rotate.
[0041] Specifically, as the first implementation mode of the second driving source, the second driving source includes a steering gear, which is fixedly connected to the boiler furnace body 15, and the output shaft of the steering gear is connected to the main shaft 26 through a conveyor belt. The steering gear and conveyor belt here are common existing technologies on the market and will not be described in detail here.
[0042] Specifically, as a second implementation of the second driving source, refer to Fig. 9 , which shows a schematic diagram of the installation structure of the second driving source of the second embodiment. It can be seen from the figure that the second driving source includes a transmission gear 32, which is concentrically fixedly connected to the main shaft 26 disposed on the outside of the boiler furnace body 15; a tooth plate 33 is provided on one side of the transmission gear 32, and the tooth plate 33 is meshed and connected with the transmission gear 32 to form a linkage; the free end of the tooth plate 33 is connected to an elastic component 34 (such as a spring, etc.) through a flange, and the other end of the elastic component 34 is connected to the outer wall of the boiler furnace body 15; a piston plate 35 is also fixedly connected to the flange, and the piston plate 35 can movably pass through the boiler furnace body 15 and is disposed on the inner side of the boiler furnace body 15, and the piston plate 35 is connected to a baffle 36 through a connecting rod; combined Fig.10, a schematic diagram of the assembly structure of the baffle 36 and the plug 37 is shown in the figure, a plug 37 is formed in the inner cavity of the steam outlet 21, a notch 38 is opened on one side of the plug 37, and the baffle 36 can movably penetrate the steam outlet 21 and form a shielding fit with the notch 38; at the same time, it is stipulated that when the steam pressure of the boiler furnace body 15 is roughly the same as the elastic force of the elastic component 34, the elastic component 34 is in a natural state, and the remaining friction force is too small to be considered here; and once the steam pressure of the boiler furnace body 15 far exceeds the elastic component 34 When the elastic force is exerted, the piston plate 35 moves toward the outside of the boiler furnace body 15 under the action of the steam pressure, and synchronously links the tooth plate 33 to move and the baffle 36 to move toward the outside of the boiler furnace body 15; when the tooth plate 33 moves, the corresponding linked transmission gear 32 and the main shaft 26 rotate, thereby indirectly linking the lifting scraper 27 to rise or fall, so as to descale the branch head 18 of the electrode 17; when the baffle 36 moves toward the outside of the boiler furnace body 15, the baffle 36 gradually loses contact with the blocking body 37, thereby realizing the exhaust of steam from the steam outlet 21.
[0043] The working principle of the descaling mechanism after the second driving source of the second embodiment is as follows: Fig.11 , which shows the use state diagram of the second driving source of the second embodiment. It can be seen from the figure that, first, when the steam pressure of the boiler furnace body 15 far exceeds the elastic force of the elastic component 34, the steam in the boiler furnace body 15 pushes the piston plate 35 to move along the c2 direction, and the moving piston plate 35 drives the tooth plate 33 and the baffle plate 36 to move along the c2 direction; the moving tooth plate 33 sequentially links the transmission gear 32 and the main shaft 26 to move along the d1 direction, and the rotating main shaft 26 drives the corresponding screw 29 to rotate through the conveyor belt. Under the joint limiting action of the screw 29 and the branch head 18 of the electrode 17, the lifting scraper 27 moves downward along the e1 direction, thereby ensuring that the lifting scraper 27 scrapes off the scale on the branch head 18 of the electrode 17 during the downward movement. Then, the scraped scale falls to the bottom of the insulating inner cylinder 16, waiting for subsequent collection and cleaning. Finally, as the steam continues to be discharged from the steam outlet 21, the steam pressure in the boiler furnace 15 decreases until the steam pressure is lower than the elastic force of the elastic component 34. Driven by the elastic component 34, the piston plate 35 retracts along the c1 direction, thereby restoring other components to their original positions, such as the baffle 36 to re-cover the notch groove 38 on the blocking body 37.
[0044] In order to ensure that the water flow ejected from the water injection pipe 25 can fully contact the branch head 18 on the corresponding electrode 17, as an optimization solution, continue to refer to Fig.11 A plurality of shower holes 39 are formed at the head of the water injection pipe 25 so that the high-temperature hot water is dispersed into a mist by the plurality of shower holes 39 when spraying out, thereby improving the contact efficiency between the high-temperature hot water and the branch head 18 of the peripheral electrode 17 .
[0045] Since a small amount of the high-temperature hot water is inevitably not evaporated during the contact between the high-temperature hot water and the electrode 17, the high-temperature hot water needs to flow back to the bottom of the boiler furnace body 15 for reuse; for this purpose, see Figure 7 As an optimization solution, the present invention opens a reflux hole 40 at the bottom of the insulating inner cylinder 16, and installs a filter screen 41 on the reflux hole 40. The function of the filter screen 41 is to intercept the scale scraped off the electrode 17.
