Description

Technical Field

[0001] The present invention relates to the technical field of substation installation, and more specifically, to an installation structure of a prefabricated substation. Background Art

[0002] A prefabricated substation (also known as a box-type substation) is a compact power distribution device that combines high-voltage switchgear, a distribution transformer, and low-voltage power distribution devices according to a certain wiring scheme. Common ones such as European box-type transformers consist of a high-voltage chamber, a transformer chamber, and a low-voltage chamber. After being fixed, the high-voltage chamber, the transformer chamber, and the low-voltage chamber form a complete substation. The installation of traditional substations requires multiple complex processes: First, it is necessary to pour a concrete foundation and embed connection components therein. After the foundation curing is completed, heavy lifting equipment needs to be used to lift the entire substation, and through high-altitude positioning, the installation holes at the bottom of the box body are accurately aligned with the foundation embedded parts. This construction method has significant technical pain points: First, the rental and use of large lifting equipment greatly increase the construction cost; Second, the millimeter-level positioning requirements of the embedded parts and the coordinated operation of high-altitude alignment pose severe challenges to the construction accuracy, and a tiny positioning deviation can lead to rework; Third, the structural characteristics of rigid connection make the substation lose its position adjustment ability after installation. If equipment relocation is required later, demolition and reconstruction must be carried out, severely restricting the layout flexibility of power facilities. This extensive installation mode has been difficult to meet the dual requirements of construction efficiency and economy in modern power grid construction. Summary of the Invention

[0003] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide an installation structure of a prefabricated substation, which effectively reduces the embedding difficulty, improves the installation efficiency, and solves the above-mentioned background technical problems.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions; An installation structure of a prefabricated substation includes an embedded plate. Four insertion rods are fixedly connected to the top of the embedded plate. A base is arranged above the embedded plate. A substation body is fixedly connected to the top of the base. Four insertion holes adapted to the insertion rods are opened on the base. Two sliding grooves are opened on the base. The inner walls of the two sliding grooves are both slidably connected with support frames. Two electric push rods fixedly connected to the base are inserted through the base. The telescopic ends of the two electric push rods are respectively fixedly connected to the two support frames. Two universal wheels are fixedly connected to the bottom of each of the two support frames. The top of each of the four insertion rods is inserted with a positioning rod slidably connected thereto. A first spring is fixedly connected to the bottom end of each of the four positioning rods. The bottom ends of the four first springs are respectively fixedly connected to the four insertion rods.

[0006] As a further description of the above technical solution: A cavity is provided inside the positioning rod. The cavity is square in shape. Two square grooves are provided on the inner wall of the cavity. Trapezoidal blocks are slidably connected to the inner walls of the two square grooves. Limiting blocks and second springs are fixedly connected to the opposite sides of the two trapezoidal blocks. The opposite sides of the two limiting blocks penetrate and extend to the outside of the positioning rod. The opposite sides of the two second springs are fixedly connected to the inner walls of the two square grooves respectively. A lead screw rotatably connected to it is inserted through the top of the positioning rod. The bottom end of the lead screw is rotatably connected to the inner bottom wall of the cavity. A square block threadedly connected to it is sleeved on the lead screw. The square block is square in shape. The outside of the square block is slidably connected to the inner wall of the cavity.

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention; Please refer to Figure 1-7, in the present invention: An installation structure of a prefabricated substation includes a buried plate 1. Four insertion rods 2 are fixedly connected to the top of the buried plate 1. A base 3 is arranged above the buried plate 1. A substation body 4 is fixedly connected to the top of the base 3. Four insertion holes 5 adapted to the insertion rods 2 are formed in the base 3. Two sliding grooves 6 are formed in the base 3. The inner walls of the two sliding grooves 6 are both slidably connected with support frames 7. Two electric push rods 8 fixedly connected to the base 3 are inserted through the base 3. The telescopic ends of the two electric push rods 8 are respectively fixedly connected to the two support frames 7. Two universal wheels 9 are fixedly connected to the bottoms of the two support frames 7. The tops of the four insertion rods 2 are all inserted with positioning rods 10 slidably connected thereto. The bottoms of the four positioning rods 10 are all fixedly connected with first springs 11. The bottoms of the four first springs 11 are respectively fixedly connected to the four insertion rods 2. The tops of the four positioning rods 10 are all in a semi-spherical shape.

[0016] In the present invention, when installing the substation body 4, first bury the buried plate 1 into the concrete foundation. The insertion rods 2 are in a positioned state when leaving the factory. Just horizontally bury the buried plate 1 in the concrete foundation to achieve the positioning of the insertion rods 2. Compared with traditional multiple independent embedded parts, the embedding difficulty is effectively reduced and the embedding speed is improved.

[0017] The base 3 is used to support the substation body 4. The cooperation of the two support frames 7 and the electric push rods 8 can realize the support of the base 3. The setting of the four universal wheels 9 allows workers to easily push the base 3 to move, and thus the position of the substation body 4 can be moved, thereby improving the flexibility of the substation body 4.

[0018] After the buried plate 1 is buried in the concrete foundation, push the base 3 towards the top of the buried plate 1 (as shown in the attachment Figure 2 ). During the process, the bottom edge position of the base 3 will first contact the bottom of the semi-spherical top of the positioning rod 10. As the base 3 moves towards the top of the buried plate 1, the base 3 will squeeze the positioning rod 10, and the positioning rod 10 will be inserted into the insertion rod 2 and compress the first spring 11 until the base 3 completely moves above the buried plate 1 (as shown in the attachment Figure 3 ). The tops of the four positioning rods 10 all contact the bottom of the base 3, and the bottoms of the four positioning rods 10 respectively compress the corresponding first springs 11. At this time, the user can adjust the corresponding position of the insertion hole 5 and the insertion rod 2 by pushing the base 3. When the insertion rod 2 is aligned with the insertion hole 5, the elastic force of the first spring 11 will be released and drive the positioning rod 10 to rise and insert into the insertion hole 5 first, thereby completing the alignment effect of one insertion rod 2 and the insertion hole 5. By this method, the four positioning rods 10 can be respectively inserted into the insertion holes 5 (as shown in the attachment Figure 4 ), and at this time, the preliminary positioning of the insertion rod 2 and the insertion hole 5 can be completed.

[0019] After the initial positioning of the four insertion rods 2 and the corresponding jacks 5, two electric push rods 8 are simultaneously activated to drive the two support frames 7 to rise. During this process, the support frames 7 will rise along the inner wall of the chute 6, and the relative distance between the base 3 and the embedded plate 1 will decrease. During this process, the jack 5 will slowly sleeve onto the positioning rod 10. Even if the positioning rod 10 and the jack 5 are not concentrically arranged, as the base 3 descends and the jack 5 completely sleeves onto the positioning rod 10, the position of the base 3 will be corrected. When the bottom of the base 3 contacts the top of the embedded plate 1, at this time, the jack 5 will sleeve into the corresponding insertion rod 2, thereby realizing the connection between the insertion rod 2 and the jack 5, and the installation of the substation body 4 can be achieved (as shown in the attached Figure 5 figure). During the installation process, only simple pushing of the base 3 by the installer is required to realize the positioning of the insertion rod 2 and the jack 5. Compared with the hoisting method, this installation structure is simple to install and saves the expenditure on the crane for hoisting.

[0020] Please refer to Figure 1-6 , in which: four guiding surfaces 12 are provided at the bottom of the base 3, and the four guiding surfaces 12 are all arc-shaped.

[0021] In the present invention, when the base 3 is in semi-spherical contact with the top end of the positioning rod 10, the setting of the guiding surface 12 can make the positioning rod 10 slide smoothly under the base 3, reduce the jerks generated when the positioning rod 10 slides under the base 3, and improve the smoothness of the installation of the substation body 4.

[0022] Please refer to Figure 1-7 , in which: a cavity 13 is provided inside the positioning rod 10, the shape of the cavity 13 is square, two square grooves 14 are provided on the inner wall of the cavity 13, trapezoidal blocks 15 are slidably connected to the inner walls of the two square grooves 14, limiting blocks 16 and second springs 17 are fixedly connected to the opposite sides of the two trapezoidal blocks 15, the opposite sides of the two limiting blocks 16 penetrate and extend to the outside of the positioning rod 10, and the opposite sides of the two second springs 17 are fixedly connected to the inner walls of the two square grooves 14 respectively. A lead screw 18 rotatably connected thereto is inserted through the top of the positioning rod 10, the bottom end of the lead screw 18 is rotatably connected to the inner bottom wall of the cavity 13, a square block 19 threadedly connected thereto is sleeved on the lead screw 18, the shape of the square block 19 is square, the outside of the square block 19 is slidably connected to the inner wall of the cavity 13, and a cross slot is provided at the top of the lead screw 18.

[0023] In the present invention, after the installation of the substation body 4 is completed, the worker aligns the screwdriver with the cross slot at the top of the lead screw 18, and can rotate the lead screw 18. After the lead screw 18 rotates, it will drive the square block 19 to descend along the inner wall of the cavity 13. During this process, the square block 19 will squeeze the inclined surface of the trapezoidal block 15. After being squeezed, the trapezoidal block 15 will slide along the inner wall of the square groove 14. During the sliding process of the trapezoidal block 15, it will compress the second spring 17 while driving the limit block 16 to extend from the positioning rod 10. Until after the two limit blocks 16 extend a certain distance, the bottoms of the limit blocks 16 are both located above the base 3, thereby realizing the effect of limiting the base 3 up and down, and improving the stability of the installation of the substation body 4; After the position adjustment of the limit block 16 is completed, the user can reverse the electric push rod 8 to drive the base 3 to rise through the support frame 7. At this time, the top of the base 3 will be in close contact with the limit block 16. At this time, the left and right positions of the base 3 will be restricted by the insertion rod 2, and the up and down positions will be restricted by the limit block 16, further improving the stability of the installation of the substation body 4.

[0024] Please refer to Figure 7 , wherein: two rollers 20 rotatably connected thereto are embedded at the bottom of the square block 19, and the outer sides of the two rollers 20 are respectively in contact with the two trapezoidal blocks 15.

[0025] In the present invention, the setting of the rollers 20 can reduce the friction between the square block 19 and the trapezoidal block 15, improve the smoothness of driving the limit block 16 to move, and reduce wear and improve the service life of the device.

[0026] Please refer to Figure 7 , wherein: a sealing cover 21 slidably connected thereto is inserted through the top of the positioning rod 10, and the bottom of the sealing cover 21 is in contact with the lead screw 18.

[0027] In the present invention, the setting of the sealing cover 21 can seal the gap between the lead screw 18 and the positioning rod 10, and prevent dust from blocking, resulting in the situation where the lead screw 18 cannot be rotated.

[0028] Please refer to Figure 3 , wherein: uniformly distributed reinforcing rods 22 are fixedly connected to the bottom of the embedded plate 1, and a reinforcing plate 23 is fixedly connected to the front of the embedded plate 1.

[0029] In the present invention, the setting of the reinforcing rods 22 can improve the stability of the embedded plate 1 embedded in the concrete foundation, and thus improve the stability of the installation of the substation body 4. The setting of the reinforcing plate 23 can reinforce the ground around the concrete, and prevent the universal wheels 9 from sinking into the ground when the base 3 is pushed towards the top of the embedded plate 1, thereby improving the practicability of the device.

[0030] Please refer to Figure 6, wherein: Two connecting rods 24 are fixedly connected between the two support frames 7, and two limiting grooves 25 slidably connected to the connecting rods 24 are formed on the base 3.

[0031] In the present invention, the arrangement of the connecting rod 24 can achieve the effect of synchronizing the two support frames 7, thereby improving the practicability of the device.

[0032] Please refer to Figure 1-6 , wherein: Two stabilizing plates 26 are fixedly connected to the top of the connecting rod 24, and the tops of the two stabilizing plates 26 penetrate through the base 3 and are in contact with the substation body 4.

[0033] In the present invention, the contact between the stabilizing plate 26 and the substation body 4 can achieve the effect of supporting the substation body 4 and improving the stability of the substation body 4.

[0034] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and its improved concept of the present invention, making equivalent replacements or changes, shall be covered by the protection scope of the present invention.
