Description

Technical Field

[0001] The invention relates to the technical field of transformers, in particular to a building transformer that is easy to maintain. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core (magnetic core). Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc.

[0003] At present, some box-type transformers need to be regularly inspected and maintained when in use. For example, a transformer that is easy to maintain is announced with the announcement number "CN219497472U". When the transformer is inspected, the door of the transformer casing needs to be opened. However, the transformer is basically installed outdoors. In windy weather, after the staff opens the door of the casing, when inspecting the transformer, since the door of the casing is opened and there is no limit mechanism, it is easy for the wind to blow the door closed and hit the staff. The internal space of the transformer casing is limited. During the maintenance process, it is inconvenient for the staff to operate. Moreover, the transformer usually contains some large and heavy components, such as iron cores and windings. When lifting the iron core, the staff needs to completely remove the casing before proceeding, which has certain disadvantages. For this reason, we propose a building transformer that is easy to maintain. Summary of the invention

[0004] The object of the present invention is to provide a building transformer that is easy to maintain, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a building transformer that is easy to maintain, comprising an outer shell, a base and a transformer body arranged on the top of the base, the outer shell is composed of an L-shaped supporting shell, a hinged seat and a protective door, the protective door and the hinged seat are provided with a one-way control component for preventing the protective door from accidentally closing, the protective door and the base are provided with a driven part for separating the outer shell, the L-shaped supporting shell and the base are provided with a linkage part for conveniently lifting the transformer body, and the protective door is provided with a winding component for winding up the cable.

[0006] Preferably, the one-way control component includes an articulated shaft, which is fixed to the side wall of the protective door, the articulated shaft passes through the articulated seat and is rotatably connected to the articulated seat, an active gear disk is fixed on the top of the articulated shaft, and a driven gear disk is slidably installed on the inner wall of the articulated seat, a connecting spring is fixed on the top of the driven gear disk, and one end of the connecting spring away from the driven gear disk is fixed to the inner wall of the articulated seat, the top of the articulated shaft is penetrated by a vertical rod and slidably connected to the vertical rod, the surface of the protective door is penetrated by a handle and slidably connected to the handle, a tension spring is fixed on one side of the handle, and the end of the tension spring away from the handle is fixed on the inner wall of the protective door, and a resistance rod is fixed on the other side of the handle. When the protective door is opened, the protective door carries the articulated shaft, so that the articulated shaft rotates at the position connected to the articulated seat. At this time, the articulated shaft The shaft drives the active latching gear plate to rotate together, and the latching teeth at the top of the active latching gear plate abut against the latching teeth at the bottom of the driven latching gear plate, pushing the driven latching gear plate to move upward. However, when the protective door is closed by strong wind, the protective door drives the hinge shaft to rotate, and the latching teeth at the top of the active latching gear plate at the top of the hinge shaft engage with the latching teeth at the bottom of the driven latching gear plate, so that the protective door cannot be closed, thereby effectively preventing the protective door from being blown closed by the wind and hitting the staff; when the protective door needs to be closed, it is only necessary to pull the handle to the side close to the tension spring, the handle drives the resistance rod to move together, the resistance rod abuts against the bottom of the vertical rod, pushing the vertical rod to move upward, the vertical rod abuts on the driven latching gear plate, pushing the driven latching gear plate to move upward, so that the driven latching gear plate is no longer engaged with the active latching gear plate, thereby releasing the limit on the hinge shaft, thereby the protective door can be pulled closed, which is convenient to use.

[0007] Preferably, the driven part includes a moving block, which is fixed to the bottom of the L-shaped supporting shell, the moving block passes through the top of the base and is slidably connected to the base, a return spring is fixed to the side of the moving block close to the center of the base, and the end of the return spring away from the moving block is fixed to the inner wall of the base, a slide plate is slidably installed on the inner wall of the base, an extrusion spring is fixed to the top of the slide plate, and the top of the extrusion spring is fixed to the inner wall of the base, a cylinder is slidably installed on the top of the slide plate, a sliding rod is fixed to the inner side of the cylinder, and the cylinder The inner side contacts the surface of the hinge shaft, and the surface of the hinge shaft is provided with a spiral groove. The end of the slide bar away from the cylinder is slidably installed on the inner side of the spiral groove. The bottom of the slide plate is hinged to a limit plate. The bottom of the slide plate is fixed with a connecting spring sheet and a fixed block. The end of the connecting spring sheet away from the slide plate is fixed to one side of the limit plate, and the fixed block is fitted with the other side of the limit plate. Under the resistance of the fixed block, the limit plate can only swing to the side away from the fixed block at the position hinged to the slide plate. The limit plate can resist the moving block to support the L-shaped The shell is limited, and when the hinge shaft rotates, the hinge shaft pushes the slide bar upward through the spiral slide groove on its own surface, and the slide bar drives the cylinder to move upward together, and the cylinder pulls the slide plate upward together, and the slide plate moves upward with the limit plate, so that the limit plate can no longer press the moving block, thereby releasing the limit on the moving block and the L-shaped supporting shell. Under the action of the reset spring, the moving block moves with the L-shaped supporting shell to the side away from the center of the base, thereby expanding the internal space and making it more convenient for the staff to maintain the transformer body. After the guard door is closed, the hinge shaft rotates to control the sliding rod to move the cylinder downward, and the cylinder pushes the sliding plate to move the limit plate downward. At this time, the staff manually pushes the L-shaped supporting shell to one side of the center of the base to reset. When the moving block moves to the position of the limit plate, the limit plate is resisted by the moving block, so that the limit plate swings to the side away from the fixed block at the position hinged with the sliding plate. When the limit plate is no longer resisted by the moving block, the limit plate can be reset under the action of the connecting spring piece, thereby resisting the moving block again, limiting the moving block, and ensuring the stability of the L-shaped supporting shell.

[0008] Preferably, the linkage portion includes an opening and closing plate, which is hinged on the top of the L-shaped supporting shell, a terminal is fixed on the top of the opening and closing plate, a cable is fixed on the surface of the terminal, one end of the cable away from the terminal passes through the wire pulley and through the top of the base and is fixed on the inner wall of the base, and a reset spring is fixed on the bottom of the opening and closing plate, one end of the reset spring away from the closing plate is fixed on the inner side of the L-shaped supporting shell. When the L-shaped supporting shells move away from each other and open, the terminal is pulled by the cable, so that the opening and closing plate rotates and opens at the position hinged with the L-shaped supporting shell, thereby making the top of the shell in an open state, which is convenient for the staff to lift the transformer body when necessary.

[0009] Preferably, the winding assembly includes a cable reel, which is rotatably mounted on a side of the protective door close to the L-shaped supporting shell, a spiral spring is fixed to the surface of the cable reel, and one end of the spiral spring away from the cable reel is fixed to the protective door. By winding the cable connecting the transformer body and the control panel around the cable reel, one end is connected to the control panel arranged on the protective door, and the other end is connected to the transformer body. When the protective door is opened and moves with the L-shaped supporting shell, the cable can be pulled by the cable to rotate and release the cable without getting stuck. When the protective door is closed and the L-shaped supporting shells are assembled together, the cable reel can rotate under the action of the spiral spring to reel the cable, thereby avoiding the influence of cluttered cables on the normal inspection and maintenance operations of the staff.

[0010] Preferably, a rubber pad is provided on one side of the opening and closing plate close to the center of the base. When the two sets of opening and closing plates are in contact with each other, the rubber pad can be squeezed to ensure sealing and prevent rainwater from falling directly on the top of the transformer body through the gap between the opening and closing plates when it rains.

[0011] Compared with the prior art, the present invention provides a building transformer that is easy to maintain and has the following features:

[0012] Beneficial effects:

[0013] 1. The building transformer which is easy to maintain has a one-way control component. When the protective door is closed by strong wind, the protective door drives the hinge shaft to rotate, and the latching teeth at the top of the active latching tooth disk at the top of the hinge shaft engage with the latching teeth at the bottom of the driven latching tooth disk, so that the protective door cannot be closed, thereby effectively preventing the protective door from being closed by the wind and hitting the staff; when the protective door needs to be closed, it is only necessary to pull the handle to move to the side close to the tension spring, and the handle drives the resistance rod to move together, and the resistance rod resists the bottom of the vertical rod, pushing the vertical rod to move upward, and the vertical rod resists on the driven latching tooth disk, pushing the driven latching tooth disk to move upward, so that the driven latching tooth disk is no longer engaged with the active latching tooth disk, so that the limit on the hinge shaft is released, so that the protective door can be pulled closed, which is convenient to use.

[0014] 2. The building transformer which is easy to maintain has a one-way control component and a driven part. When the hinge shaft rotates, the hinge shaft pushes the slide bar to move upward through the spiral slide groove on its surface, and the slide bar drives the cylinder to move upward together. The cylinder pulls the slide bar to move upward together, and the slide bar moves upward together with the limit plate, so that the limit plate can no longer press the moving block, thereby releasing the limit on the moving block and the L-shaped support shell. Under the action of the reset spring, the moving block moves with the L-shaped support shell to the side away from the center of the base, thereby expanding the internal space and making it more convenient for the staff to operate the transformer. The pressure device body is maintained. When the protective door is closed, the hinge shaft rotates to control the sliding rod to move the cylinder downward. The cylinder pushes the sliding plate to move the limit plate downward. At this time, the staff manually pushes the L-shaped support shell to one side of the center of the base to reset. When the moving block moves to the position of the limit plate, the limit plate is resisted by the moving block, so that the limit plate swings to the side away from the fixed block at the position hinged with the sliding plate. When the limit plate is not resisted by the moving block, the limit plate can be reset under the action of the connecting spring piece, thereby resisting the moving block again, limiting the moving block, and ensuring the stability of the L-shaped support shell.

[0015] 3. The building transformer which is easy to maintain has a one-way control component, a driven part and a linkage part. When the L-shaped support shells are opened away from each other, the terminal is pulled by the cable, so that the opening and closing plate is rotated and opened at the position hinged with the L-shaped support shell, so that the top of the shell is in an open state, which is convenient for the staff to lift the transformer body when necessary.

[0016] 4. The easy-to-maintain building transformer has a winding assembly. When the protective door is opened and moves with the L-shaped support shell, the cable can be pulled by the cable to rotate and release the cable without getting stuck. When the protective door is closed and the L-shaped support shells are assembled, the winding drum can rotate under the action of the vortex spring to wind up the cable, thereby preventing the cluttered cables from affecting the normal inspection and maintenance operations of the staff.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1-Figure 10As shown, the present invention provides a technical solution: a building transformer that is easy to maintain, comprising a shell 1, a base 6 and a transformer body 7 arranged on the top of the base 6, the shell 1 is composed of an L-shaped supporting shell 11, a hinged seat 12 and a protective door 13, the protective door 13 and the hinged seat 12 are provided with a one-way control component 2 for preventing the protective door 13 from being accidentally closed, the protective door 13 and the base 6 are provided with a driven part 3 for separating the shell 1, the L-shaped supporting shell 11 and the base 6 are provided with a linkage part 4 for conveniently lifting the transformer body 7, and the protective door 13 is provided with a winding component 5 for winding up the cable.

[0030] The one-way control assembly 2 includes an articulated shaft 21, which is fixed to the side wall of the protective door 13. The articulated shaft 21 passes through the articulated seat 12 and is rotatably connected to the articulated seat 12. An active card tooth plate 22 is fixed to the top of the articulated shaft 21. A driven card tooth plate 23 is slidably mounted on the inner wall of the articulated seat 12. A connecting spring 24 is fixed to the top of the driven card tooth plate 23. One end of the connecting spring 24 away from the driven card tooth plate 23 is fixed to the inner wall of the articulated seat 12. The top of the articulated shaft 21 is connected to the vertical rod. The protective door 13 is provided with a handle 26 which penetrates the protective door 13 and is slidably connected to the vertical rod 25. A tension spring 27 is fixed to one side of the handle 26. The end of the tension spring 27 away from the handle 26 is fixed to the inner wall of the protective door 13. The other side of the handle 26 is fixed to a resisting rod 28. When the protective door 13 is opened, the protective door 13 carries the hinge shaft 21, so that the hinge shaft 21 rotates at the position connected to the hinge seat 12. At this time, the hinge shaft 21 drives the active The latching teeth disc 22 rotates together, and the latching teeth at the top of the active latching teeth disc 22 abut against the latching teeth at the bottom of the driven latching teeth disc 23, pushing the driven latching teeth disc 23 to move upward. However, when the protective door 13 is closed by strong wind, the protective door 13 drives the hinge shaft 21 to rotate, and the latching teeth at the top of the active latching teeth disc 22 at the top of the hinge shaft 21 engage with the latching teeth at the bottom of the driven latching teeth disc 23, so that the protective door 13 cannot be closed, thereby effectively preventing the protective door 13 from being closed by the wind and hitting the staff. When the protective door 13 needs to be closed, it is only necessary to pull the handle 26 to move toward the side close to the tension spring 27. The handle 26 drives the resistance rod 28 to move together. The resistance rod 28 resists the bottom of the vertical rod 25, pushing the vertical rod 25 to move upward. The vertical rod 25 resists on the driven gear plate 23, pushing the driven gear plate 23 to move upward, so that the driven gear plate 23 is no longer engaged with the active gear plate 22, thereby releasing the limit on the hinge shaft 21, so that the protective door 13 can be pulled closed, which is convenient to use.

[0031] In this embodiment, the driven part 3 includes a moving block 31, which is fixed at the bottom of the L-shaped supporting shell 11. The moving block 31 passes through the top of the base 6 and is slidably connected to the base 6. A return spring 32 is fixed on the side of the moving block 31 close to the center of the base 6. The end of the return spring 32 away from the moving block 31 is fixed on the inner wall of the base 6. A slide plate 34 is slidably installed on the inner wall of the base 6. An extrusion spring 35 is fixed on the top of the slide plate 34. The top of the extrusion spring 35 is fixed on the inner wall of the base 6. A cylinder 33 is slidably installed on the top of the slide plate 34. A sliding rod 36 is fixed on the inner side of the cylinder 33. The inner side of the cylinder 33 contacts the surface of the hinge shaft 21. The surface of the hinge shaft 21 is provided with a spiral groove 37, and the end of the slide rod 36 away from the cylinder 33 is slidably installed on the inner side of the spiral groove 37. The bottom of the slide plate 34 is hinged to a limit plate 38, and the bottom of the slide plate 34 is fixed with a connecting spring piece 39 and a fixed block 310. The end of the connecting spring piece 39 away from the slide plate 34 is fixed to one side of the limit plate 38, and the fixed block 310 is fitted with the other side of the limit plate 38. Under the resistance of the fixed block 310, the limit plate 38 can only swing to the side away from the fixed block 310 at the position hinged to the slide plate 34. The limit plate 38 can resist on the moving block 31 to limit the L-shaped support shell 11. When the hinge shaft 2 When the hinge shaft 21 rotates, the spiral groove 37 on its surface pushes the slide bar 36 to move upward, and the slide bar 36 drives the cylinder 33 to move upward together. The cylinder 33 pulls the slide plate 34 to move upward together, and the slide plate 34 moves upward together with the limit plate 38, so that the limit plate 38 can no longer press the moving block 31, thereby releasing the limit of the moving block 31 and the L-shaped support shell 11. Under the action of the reset spring 32, the moving block 31 moves with the L-shaped support shell 11 to the side away from the center of the base 6, thereby expanding the internal space, making it more convenient for the staff to maintain the transformer body 7. When the protective door 13 is closed, the hinge shaft 21 is The shaft 21 rotates to control the slide bar 36 to move the cylinder 33 downward, and the cylinder 33 pushes the slide plate 34 to move the limit plate 38 downward. At this time, the staff manually pushes the L-shaped support shell 11 to move to one side of the center of the base 6 to reset. When the moving block 31 moves to the position of the limit plate 38, the limit plate 38 is resisted by the moving block 31, so that the limit plate 38 swings to the side away from the fixed block 310 at the position hinged with the slide plate 34. When the limit plate 38 is not resisted by the moving block 31, the limit plate 38 can be reset under the action of the connecting spring piece 39, thereby resisting the moving block 31 again, limiting the moving block 31, and ensuring the stability of the L-shaped support shell 11.

[0032] The linkage part 4 includes an opening and closing plate 41, which is hinged on the top of the L-shaped supporting shell 11. A terminal 42 is fixed to the top of the opening and closing plate 41, and a cable 43 is fixed to the surface of the terminal 42. The end of the cable 43 away from the terminal 42 passes through the wire pulley and passes through the top of the base 6 to be fixed on the inner wall of the base 6. A reset spring 44 is fixed to the bottom of the opening and closing plate 41, and the end of the reset spring 44 away from the closing plate 41 is fixed to the inner side of the L-shaped supporting shell 11. When the L-shaped supporting shells 11 are moved away from each other and opened, the terminal 42 is pulled by the cable 43, so that the opening and closing plate 41 is rotated and opened at the position hinged with the L-shaped supporting shell 11, so that the top of the shell 1 is in an open state, which is convenient for the staff to lift the transformer body 7 when necessary.

[0033] The winding assembly 5 includes a cable reel 51, which is rotatably mounted on a side of the protective door 13 close to the L-shaped supporting shell 11. A spiral spring 52 is fixed to the surface of the cable reel 51, and one end of the spiral spring 52 away from the cable reel 51 is fixed to the protective door 13. By winding the cable connecting the transformer body 7 and the control panel around the cable reel 51, one end is connected to the control panel arranged on the protective door 13, and the other end is connected to the transformer body 7. When the protective door 13 is opened and moves with the L-shaped supporting shell 11, the cable can be pulled by the cable to rotate and release the cable without getting stuck. When the protective door 13 is closed and the L-shaped supporting shells 11 are assembled together, the cable reel 51 can be rotated under the action of the spiral spring 52 to reel the cable, thereby preventing the clutter of cables from affecting the normal inspection and maintenance operations of the staff.

[0034] A rubber pad 8 is provided on one side of the opening and closing plate 41 close to the center of the base 6. When the two groups of opening and closing plates 41 are in contact with each other, the rubber pad 8 can be squeezed to ensure sealing and prevent rainwater from falling directly on the top of the transformer body 7 through the gap between the opening and closing plates 41 when it rains.

[0035] Based on the above embodiment, when the transformer body 7 needs to be maintained, the staff opens the protective door 13, and the protective door 13 carries the hinge shaft 21, so that the hinge shaft 21 rotates at the position connected to the hinge seat 12. At this time, the hinge shaft 21 drives the active gear plate 22 to rotate together, and the teeth at the top of the active gear plate 22 abut against the teeth at the bottom of the driven gear plate 23, pushing the driven gear plate 23 to move upward. However, when the protective door 13 is blown closed by strong wind, the protective door 13 drives the hinge shaft 21 to rotate, and the teeth at the top of the active gear plate 22 at the top of the hinge shaft 21 engage with the teeth at the bottom of the driven gear plate 23, so that the protective door 13 cannot be closed, thereby effectively preventing the protective door 13 from being blown closed by the wind and hitting the staff.

[0036] When the hinge shaft 21 rotates, the hinge shaft 21 pushes the slide bar 36 to move upward through the spiral slide groove 37 opened on its own surface, and the slide bar 36 drives the cylinder 33 to move upward together, and the cylinder 33 pulls the slide plate 34 to move upward together, and the slide plate 34 moves upward together with the limit plate 38, so that the limit plate 38 can no longer press the moving block 31, thereby releasing the limit on the moving block 31 and the L-shaped support shell 11. Under the action of the reset spring 32, the moving block 31 moves with the L-shaped support shell 11 to the side away from the center of the base 6, thereby expanding the internal space, making it more convenient for the staff to maintain the transformer body 7.

[0037] When the L-shaped support shell 11 moves to the side away from the center of the base 6, the terminal 42 is pulled by the cable 43, so that the opening and closing plate 41 rotates and opens at the position hinged to the L-shaped support shell 11, so that the top of the shell 1 is in an open state, which is convenient for the staff to lift the transformer body 7 when necessary.

[0038] After the maintenance is completed, the staff only needs to pull the handle 26 to the side close to the tension spring 27, and the handle 26 drives the resistance rod 28 to move together. The resistance rod 28 resists the bottom of the vertical rod 25, pushing the vertical rod 25 to move upward, and the vertical rod 25 resists on the driven gear plate 23, pushing the driven gear plate 23 to move upward, so that the driven gear plate 23 is no longer engaged with the active gear plate 22, thereby releasing the limit on the hinge shaft 21, so that the protective door 13 can be pulled closed, which is convenient to use.

[0039] At this time, you only need to manually push the L-shaped support shell 11 to move it to one side of the center of the base 6 to reset. When the moving block 31 moves to the position of the limit plate 38, the limit plate 38 is resisted by the moving block 31, so that the limit plate 38 swings to the side away from the fixed block 310 at the position hinged with the slide plate 34. When the limit plate 38 is no longer resisted by the moving block 31, the limit plate 38 can be reset under the action of the connecting spring piece 39, thereby re-contacting the moving block 31 to limit the moving block 31 and ensure the stability of the L-shaped support shell 11. At the same time, the cable 43 cannot continue to pull the terminal 42. Under the action of the reset spring piece 44, the opening and closing plate 41 is closed again to complete the reset.

[0040] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
