Description

Technical Field

[0001] The present invention relates to the technical field of transformer quick installation, in particular to a 10KV pole-mounted transformer that can be quickly installed. Background Art

[0002] The 10KV pole-mounted transformer platform complete set is a new product launched by the State Grid to meet the requirements of the construction and development of smart distribution networks. It has the advantages of safety, reliability, durability, reasonable structure, reduced construction, and economical and efficient. It is convenient to unify construction standards, unify equipment specifications, and facilitate operation and maintenance and operating costs. The 10KV pole-mounted transformer platform complete set mainly includes transformers, drop-out fuses, detachable lightning rods, low-voltage integrated distribution boxes, insulated wires from 10KV down leads to the integrated distribution box incoming lines, and iron accessories. The pole-mounted transformer platform complete set mainly consists of power transformers, outdoor high-voltage AC vacuum circuit breakers, outdoor high-voltage drop-out fuses, outdoor high-voltage zinc oxide arresters, low-voltage integrated distribution boxes, cables, brackets and their accessories.

[0003] When installing pole-mounted transformers, the commonly used installation method in the industry mainly relies on lifting equipment such as cranes and hoists. The specific operation process is to use the lifting equipment to lift the pole-mounted transformer as a whole off the ground and raise it to the preset installation height on the top of the pole. Then, its posture and position are adjusted with manual assistance, and finally, fasteners such as bolts are used to firmly fix it on the crossarm or bracket structure of the pole. However, since pole-mounted transformers usually have a large weight and a relatively large physical volume, during the lifting operation, the transformer body is extremely susceptible to interference from various internal and external factors. For example, the slight shaking caused by the operation of the lifting equipment itself causes the hoisted transformer to easily shake irregularly in the air, which makes it more difficult to install the pole-mounted transformer.

[0004] In view of this, we propose a 10KV pole-mounted transformer that can be quickly installed. Summary of the Invention

[0005] The object of the present invention is to provide a 10KV pole-mounted transformer that can be installed quickly, so as to solve the problem mentioned in the above background technology that pole-mounted transformers usually have a large weight and a relatively large physical volume. During the hoisting operation, the transformer body is easily interfered with by various internal and external factors, such as the slight shaking caused by the operation of the hoisting equipment itself, which causes the hoisted transformer to easily shake irregularly in the air, thereby making it more difficult to install the pole-mounted transformer. To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a 10KV pole-mounted transformer that can be quickly installed, comprising two support seats, support plates fixedly provided on opposite sides of the two support seats, a transformer body provided on the top of the support plates, a movable frame overlapped on the top of the support seat, two support bars movably plugged into the interior of the two support seats, the tops of the four support bars pass through the movable frame and are fixedly provided with C-shaped connecting bars, a movable mechanism for quickly installing the transformer body is slidingly provided inside the movable frame, two T-shaped bars are overlapped on the top of the support plates, and a fixing mechanism for limiting the transformer body is slidingly provided on the upper sides of the two T-shaped bars, two electric poles are provided on the front side of the support seat, and mounting bars are fixedly sleeved on the sides of the two electric poles.

[0006] Preferably, the moving mechanism includes two threaded rods, which are rotatably arranged inside the support seat, the top ends of the threaded rods pass through the moving frame and rotatably cooperate with the bottom of the C-shaped connecting bar, the support seat on the left is inlaid with a double-axis motor, and the support seat on the right is rotatably provided with a connecting shaft, the lower rotating shaft of the double-axis motor and the side surface of the connecting shaft are sleeved with a chain, and the chain is driven by the lower rotating shaft of the double-axis motor and the connecting shaft, and the upper rotating shaft of the double-axis motor and the upper rotating shaft of the connecting shaft are respectively fixedly connected to the bottom ends of the two threaded rods, and the support plate is provided with a through groove for facilitating the movement of the chain, and the chain is driven by the double-axis motor to achieve precise synchronous rotation of the threaded rods on the left and right sides. The cooperation between the threaded rods and the moving frame converts the rotational motion into a smooth and reliable linear lifting motion, ensuring that the transformer body always maintains a horizontal posture during the lifting process without the risk of tilting. The design of the through groove provides a smooth and unobstructed running space for the chain, effectively avoiding friction or interference between the chain and the support plate, and ensuring the long-term stable operation and low failure rate of the transmission system.

[0007] The top end of the long rod is connected to the top of the C-shaped connecting bar and is fixedly provided with a rotating bar. The side of the long rod is fixedly provided with a square bar, and a square groove is opened in the side of the long rod, and the connecting rod and the T-shaped bar are accurately and labor-savingly driven to deflect by rotating the worm. The matching design of the square bar and the square groove enables the long rod to transmit torque to drive the worm, which greatly simplifies the operation steps. The position of the T-shaped bar can be adjusted by rotating the rotating bar at the top of the long rod. The operation is intuitive and convenient, and the position locking is stable, which provides a high-precision adjustment means and reliable holding force for the subsequent installation and positioning of the transformer.

[0008] Preferably, mounting blocks are fixedly provided on the left and right sides of the front and rear sides of the transformer body, a circular groove is provided on the top of the mounting block, and an arc groove is provided on the bottom of the two mounting blocks on the front side. The mounting blocks and their circular grooves and arc grooves symmetrically arranged on the transformer body provide a standardized and reliable connection interface for the fixing mechanism. The circular groove is mainly used to withstand the vertical force and achieve positioning, and the arc groove on the front side is specially designed to limit the transformer body in a specific direction. This combined design ensures that the transformer body can effectively resist the shaking caused by the transformer body when it moves after being fixed, and significantly improves the overall stability and anti-displacement ability after installation.

[0009] Preferably, the fixing mechanism includes two long frames, which are respectively fixed on the rear side of the top of the T-shaped bar, the interior of the long frame slides with the side of the mounting block, the middle of the inner wall of the long frame is provided with a first Chinese character groove, a Chinese character block is slidably provided inside the first Chinese character groove, the top of the transverse block of the Chinese character block is fixedly provided with a first compression spring, the top of the first compression spring is fixedly connected to the upper side of the inner wall of the transverse groove of the first Chinese character groove, the front and rear sides of the bottom of the vertical block of the Chinese character block are provided with a 45° bevel angle, the Chinese character The bottom of the vertical block of the block slides with the inside of the circular groove. When the T-shaped bar drives the long frame to move to the installation block position, the beveled angle design at the bottom of the Chinese-shaped block can guide it to slide smoothly into the circular groove of the installation block. The first compression spring continuously provides downward pressure to ensure that the Chinese-shaped block is firmly embedded in the bottom of the circular groove, forming a strong vertical locking force. The design of the first Chinese-shaped groove ensures that the Chinese-shaped block can only move in the vertical direction. The locking process is automatic and efficient. When releasing, you only need to overcome the spring force and lift it vertically. The operation is simple and reliable, which greatly simplifies the installation and disassembly process of the transformer body.

[0010] The L-shaped block is fixed on the inner wall of the L-shaped groove, and the bottom of the L-shaped block is fixed on the side opposite to the inner wall of the L-shaped groove. The top of the vertical block of the L-shaped block slides with the side wall of the inner wall of the arc groove. This L-shaped block cooperates with the arc groove of the mounting block on the front side of the transformer body to form an effective constraint for the front and rear displacement of the transformer body. Under the action of the second compression spring, the L-shaped block automatically and tightly fits the side wall of the arc groove to prevent the transformer body from moving forward due to external factors such as shaking and vibration. When the transformer body has a tendency to move forward, the contact friction and geometric limit of its vertical block with the side wall of the arc groove immediately generates strong resistance to its displacement through the contact friction and geometric limit of its vertical block and the side wall of the arc groove. This design cooperates with the vertical locking force of the middle-shaped block to form an all-round fixing effect on the transformer body, significantly enhancing the transformer's anti-overturning and anti-displacement capabilities under complex working conditions, and ensuring the safety of the transformer body when moving.

[0011] Preferably, the mounting strip includes two clamps, which are fixedly sleeved on the sides of two electric poles respectively, and long strips are fixedly provided on the opposite sides of the two clamps, and a groove is provided on the top of the inner wall of the long strip, and two T-shaped blocks are slidingly provided inside the groove, and four T-shaped blocks are fixed on the top of a group of two, and a fixing strip is provided, and a plurality of slots are provided in a straight line at an equal distance at the bottom of the inner wall of the groove. The mounting strip provides a high degree of flexibility and adaptability, and the clamps ensure that the mounting strip can be firmly mounted on the electric poles. The two independently slidable T-shaped block groups allow the spacing between the fixing strips to be freely adjusted to a large extent according to the actual spacing of the electric poles. The multiple slots at the bottom of the groove provide many optional points for locking the fixed position. This design solves the problem of different sizes of transformer bodies required for different sites, so that the transformer body can quickly adapt to various installation environments, greatly improving the versatility and on-site deployment efficiency of the equipment.

[0012] Preferably, a second center-shaped groove is provided inside the fixing bar, and a center-shaped bar is slidably provided inside the second center-shaped groove, and the bottom of the vertical bar of the center-shaped bar passes through the bottom of the T-shaped block and slides with the inner wall of one of the several slots, and a third compression spring is fixedly provided on the top of the horizontal bar of the center-shaped bar, and the top of the third compression spring is fixedly matched with the upper side of the inner wall of the horizontal groove of the second center-shaped groove, and the top of the vertical bar of the center-shaped bar extends to the upper side of the vertical groove of the second center-shaped groove and is provided with a threaded groove, and the top of the vertical bar of the center-shaped bar slides with the side of the inner wall of the circular groove. This mechanism realizes a fast and stable vertical connection and locking between the fixing bar and the transformer mounting block, when the vertical bar of the center-shaped bar is inserted into the mounting block The third compression spring automatically pushes the middle-shaped bar downward so that the bottom of the vertical bar is reliably inserted into the preset slot at the bottom of the groove. This step also locks the position of the T-shaped block inside the groove. The action of inserting into the slot provides a strong anti-pull-out force to ensure that the fixing bar is fixed in position. At the same time, the top of the middle-shaped bar enters the circular groove of the transformer mounting block and fits tightly with the groove wall under the pressure of the spring, forming a key locking point that ultimately firmly constrains the transformer body to the fixing bar. The threaded groove design on the top makes it convenient to fix the transformer body 3 with a nut through the mounting block on the gas side. The entire connection process is simple to operate, reliable locking, and easy to disassemble. It is the core guarantee for efficient and stable connection between the transformer body and the basic support structure.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the present invention, a dual-axis motor drives the two threaded rods to rotate through a chain and a connecting shaft, and at the same time, the support bar limits the two movable frames, so that the two movable frames drive the transformer body to move upward, and then the two long rods, the square bar and the worm on its side are driven to rotate through the rotating bar, so that the worm drives the connecting rod and the T-shaped bar to deflect through the worm gear, and the transformer body can be quickly driven to move to the side of the electric pole, thereby reducing the shaking of the transformer body when moving and increasing the convenience of installing the transformer body.

[0015] In the present invention, after the transformer body is moved to a suitable installation height, the transformer body is moved as a whole toward the front side of the T-shaped bar. At this time, the pressure generated by the rear mounting block driving the circular groove forward causes the center-shaped block to move upward and compresses the first compression spring, so that the lower side of the vertical block of the center-shaped block is separated from the circular groove. At the same time, the pressure generated by the forward movement of the two front mounting blocks and the arc-shaped groove squeezes the L-shaped block downward, so that the mounting block is separated from the contact with the L-shaped block, and the fixed transformer body can be moved out from the side of the T-shaped bar, thereby ensuring the stability of the transformer body during movement and making it more convenient to take out the transformer body.

[0016] In the present invention, by moving up two middle-shaped bars, the third compression spring is squeezed, and the lower vertical bar of the middle-shaped bar moves out from the inside of the slot, releasing the fixation of the T-shaped block. Then, according to the size of the transformer, two groups of T-shaped blocks are driven by two fixing bars to move to a suitable position inside the groove. Secondly, the transformer body is placed on the fixing bar, and the round groove is aligned with the upper vertical bar of the middle-shaped bar. Secondly, by using nuts for threaded connection, the transformer body can be quickly fixed on the upper side of the utility pole. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technical personnel in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0030] See also Figures 1 to 11 The present invention provides a technical solution: a 10KV pole-mounted transformer that can be quickly installed, comprising two support bases 1, support plates 2 are fixedly provided on opposite sides of the two support bases 1, a transformer body 3 is provided on the top of the support plate 2, a movable frame 6 is overlapped on the top of the support base 1, two support bars 4 are movably inserted into the interior of the two support bases 1, the tops of the four support bars 4 pass through the movable frame 6 and are fixedly provided with a C-shaped connecting bar 5, a movable mechanism 7 for quickly installing the transformer body 3 is slidingly provided inside the movable frame 6, two T-shaped bars 8 are overlapped on the top of the support plate 2, and a fixing mechanism 9 for limiting the transformer body 3 is slidingly provided on the upper side of the two T-shaped bars 8, two electric poles 10 are provided on the front side of the support base 1, and mounting bars 11 are fixedly sleeved on the sides of the two electric poles 10.

[0031] Example 1:

[0032] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 , this embodiment provides a technical solution:

[0033] The moving mechanism 7 includes two threaded rods 701, which are rotatably arranged inside the support seat 1. The top of the threaded rod 701 passes through the moving frame 6 and rotatably cooperates with the bottom of the C-shaped connecting bar 5. A double-axis motor 702 is embedded in the interior of the left support seat 1, and a connecting shaft 703 is rotatably arranged inside the right support seat 1. The lower rotating shaft of the double-axis motor 702 and the side of the connecting shaft 703 are sleeved with a chain 704. The chain 704 is driven and cooperated with the connecting shaft 703 through the lower rotating shaft of the double-axis motor 702. The upper rotating shaft of the double-axis motor 702 and the upper rotating shaft of the connecting shaft 703 are fixedly connected to the bottom ends of the two threaded rods 701 respectively. A through slot 705 is provided inside the support plate 2 to facilitate the movement of the chain 704. It should be noted here that the side of the lower rotating shaft of the double-axis motor 702 and the side of the connecting shaft 703 are sleeved with a linkage shaft that cooperates with the chain 704.

[0034] The internal rotation of the movable frame 6 is provided with a connecting rod 601, and the side surfaces of the two connecting rods 601 are fixedly connected to the tops of the vertical bars of the two T-shaped bars 8 respectively. A worm gear 602 is fixedly sleeved on the side surface of the connecting rod 601. The internal rotation of the movable frame 6 is provided with a worm 603, and the worm 603 is transmission-connected to the worm gear 602. A long rod 605 is movably inserted into the worm 603. The bottom end of the long rod 605 is rotationally matched with the top of the support base 1. The top end of the long rod 605 passes through the top of the C-shaped connecting bar 5 and is fixedly provided with a rotating bar 604. A square bar 606 is fixedly provided on the side surface of the long rod 605. A square groove 607 that cooperates with the square bar 606 is opened inside the worm 603;

[0035] The rotation of the two moving frames 6 overcomes the gravity and moves upwards in a stable manner along the direction defined by the support bar 4. They are all firmly connected to the moving frame 6 or its internal structure, so these components are lifted synchronously as a whole as the moving frame 6 rises. When the operator observes that the transformer body 3 is lifted to a predetermined height suitable for installation, the lifting action is paused, and the azimuth adjustment stage is entered: the operator manually deflects the two rotating bars 604 from the initial position by an angle. The deflection of the rotating bar 604 will drive the square bar 606 fixed on its side to undergo synchronous angle changes. Since the square bar 606 is connected to the worm 603, the deflection of the square bar 606 forces the worm 603 to rotate accordingly around its own axis. The rotating worm 603 then drives the two worm wheels 602 meshing with it to rotate. The rotation of the worm wheel 602 drives the connecting rod 601 to rotate, and then drives the entire T-shaped bar 8 structure to deflect horizontally around its vertical axis. Finally, the transformer body 3 firmly placed on the top horizontal plate of the T-shaped bar 8 also undergoes precise angle adjustment.

[0036] Example 2:

[0037] See also Figure 2 、 Figure 3 、 Figure 4 、、 Figure 7 、 Figure 8 , this embodiment provides a technical solution:

[0038] Mounting blocks 301 are fixedly provided on both the left and right sides of the front and rear sides of the transformer body 3. A circular groove 302 is provided on the top of the mounting blocks 301, and an arc groove 303 is provided on the bottom of the two mounting blocks 301 on the front side.

[0039] The fixing mechanism 9 includes two long frames 901, which are respectively fixed on the rear side of the top of the horizontal bar of the T-shaped bar 8. The interior of the long frame 901 slides with the side of the mounting block 301. A first center-shaped groove 904 is provided in the middle of the inner wall of the long frame 901. A center-shaped block 902 is slidably provided inside the first center-shaped groove 904. A first compression spring 903 is fixed on the top of the horizontal block of the center-shaped block 902. The top of the first compression spring 903 is fixedly connected to the upper side of the inner wall of the horizontal groove of the first center-shaped groove 904. The front and rear sides of the bottom of the vertical block of the center-shaped block 902 are provided with a 45° bevel angle, and the bottom of the vertical block of the center-shaped block 902 slides with the inside of the circular groove 302.

[0040] An L-shaped groove 802 is provided on the front side of the interior of the horizontal bar of the T-shaped bar 8. An L-shaped block 803 is slidably provided inside the L-shaped groove 802. A second compression spring 801 is fixedly provided on the side of the bottom of the L-shaped block 803 opposite to the inner wall of the horizontal groove of the L-shaped groove 802. The top of the vertical block of the L-shaped block 803 is slidably engaged with the side of the inner wall of the arc-shaped groove 303.

[0041] In this embodiment, when the transformer body 3 is moved to the upper side of the horizontal bars of the two T-shaped bars 8, the two rear mounting blocks 301 are moved to the inside of the long frame 901, and the mounting blocks 301 squeeze the middle-shaped block 902 when moving, causing it to move upward and drive the first compression spring 903 to compress. When the circular groove 302 at the top of the mounting block 301 moves to the same center as the bottom of the vertical block of the middle-shaped block 902, the middle-shaped block 902 is reset downward by the rebound force of the first compression spring 903. At the same time, the two arc grooves 303 at the bottom of the two front mounting blocks 301 of the transformer body 3 contact the top of the vertical block of the L-shaped block 803, and the transformer body 3 can be quickly fixed.

[0042] Example 3:

[0043] See also Figure 9 、 Figure 10 、 Figure 11 , this embodiment provides a technical solution:

[0044] The mounting strip 11 includes two clamps 1101, which are fixedly sleeved on the sides of the two poles 10 respectively. A long strip 1102 is fixedly provided on the opposite sides of the two clamps 1101. A groove 1103 is provided at the top of the inner wall of the long strip 1102. Two T-shaped blocks 1104 are slidably provided inside the groove 1103. The tops of the four T-shaped blocks 1104 are fixed in groups of two, and a fixing strip 1105 is provided on each of the tops. A plurality of slots 1108 are provided in a straight line at equal distances at the bottom of the inner wall of the groove 1103.

[0045] A second center-shaped groove 1106 is provided inside the fixed bar 1105, and a center-shaped bar 1107 is slidably provided inside the second center-shaped groove 1106. The bottom of the vertical bar of the center-shaped bar 1107 passes through the bottom of the T-shaped block 1104 and slides with the inner wall of one of the plurality of slots 1108. A third compression spring 1109 is fixedly provided on the top of the horizontal bar of the center-shaped bar 1107. The top of the third compression spring 1109 is fixedly fitted with the upper side of the inner wall of the horizontal groove of the second center-shaped groove 1106. The top of the vertical bar of the center-shaped bar 1107 extends to the upper side of the vertical groove of the second center-shaped groove 1106 and is provided with a threaded groove 1110. The top of the vertical bar of the center-shaped bar 1107 slides with the side surface of the inner wall of the circular groove 302.

[0046] In this embodiment, after the strip 1102 is fixed to the upper side of the utility pole 10 by the clamp 1101, the transformer body 3 is moved to a suitable height and moved to the upper side of the strip 1102. Then, the circular grooves 302 on the top of the four mounting blocks 301 are aligned with the upper vertical bars of the U-shaped strip 1107, and the transformer body 3 can be quickly fixed by nuts.

[0047] The use method and advantages of the present invention: When the 10KV pole-mounted transformer that can be quickly installed is in operation and use, the working process is as follows:

[0048] like Figures 1 to 11 As shown, after the transformer body 3 is fixed on the upper side of the T-shaped bar 8, the two threaded rods 701 are driven to rotate by the dual-axis motor 702 through the chain 704 and the connecting shaft 703. At the same time, the two movable frames 6 are limited by the support bar 4, so that the two movable frames 6 drive the transformer body 3 to move upward horizontally and vertically. When it moves to a suitable height, the two long rods 605, the square bar 606 and the worm 603 on its side are driven to rotate by the rotating bar 604, so that the rotating worm 603 drives the connecting rod 601 and the T-shaped bar 8 to deflect through the worm gear 602, so that the transformer body 3 can be quickly driven to move to the side of the electric pole 10, thereby reducing the shaking caused by the movement of the transformer body 3 and increasing the convenience of installing the transformer body 3.

[0049] When the transformer body 3 is moved to a suitable installation height, the transformer body 3 is moved as a whole toward the front side of the T-shaped bar 8. At this time, the rear mounting block 301 drives the circular groove 302 on its back to move forward. The pressure generated during the forward movement causes the middle-shaped block 902 to move upward and compresses the first compression spring 903, so that the lower side of the vertical block of the middle-shaped block 902 is separated from the inside of the circular groove 302. At the same time, the pressure generated when the two front mounting blocks 301 and the arc groove 303 at their bottom move forward squeezes the L-shaped block 803 downward, so that the two front mounting blocks 301 are separated from the contact with the L-shaped block 803, and the fixed transformer body 3 can be quickly moved out from the side of the T-shaped bar 8, thereby ensuring the stability of the transformer body 3 during movement and making it easier to take out the transformer body 3.

[0050] By moving the two center-shaped bars 1107 upward, the third compression spring 1109 is squeezed, and the lower vertical bar of the center-shaped bar 1107 is moved out from the inside of the slot 1108, thereby releasing the fixation of the T-shaped block 1104. Then, according to the size of the transformer, two T-shaped blocks 1104 are driven by the two fixing bars 1105 to move to a suitable position inside the groove 1103. Secondly, the transformer body 3 is placed on the upper side of the fixing bar 1105, and the circular groove 302 is aligned with the upper vertical bar of the center-shaped bar 1107. Then, a nut is used to connect with the threaded groove 1110 to quickly fix the transformer body 3 on the upper side of the utility pole 10.

[0051] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
