Description

Technical Field

[0001] This invention relates to the field of prefabricated transformer boxes, and more specifically, to a prefabricated photovoltaic power prefabricated transformer box foundation. Background Technology

[0002] A prefabricated substation is a type of high-voltage switchgear, distribution transformer, and low-voltage power distribution device. It integrates the distribution room into a single enclosure, replacing the traditional distribution room. The prefabricated substation needs to be housed within a prefabricated substation foundation, with cables passing through the foundation. Traditional prefabricated substation foundations are constructed using a "wet method," i.e., on-site pouring and masonry.

[0003] In existing technologies, prefabricated photovoltaic power transformer bases typically house the transformer within the main body of the transformer box. When in use, the transformer box foundation has a certain internal height, requiring access via stairs. However, since the transformer box is located outdoors, the stairs, exposed to wind and rain for extended periods, can rust. This makes climbing the stairs difficult for users. Firstly, rust can cause injury to users; secondly, prolonged exposure can cause the crossbars to sway and tilt, resulting in insufficient support and rendering the stairs unusable. Furthermore, existing stairs are generally fixed and cannot be moved, further reducing the internal space within the transformer box foundation and hindering user movement. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the technical problem to be solved by the present invention is to propose a prefabricated photovoltaic power box transformer foundation, which can improve the support force of the crossbar on the ladder, and at the same time, by retracting the ladder, it can increase the user's movement space inside the box transformer compartment.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] This invention provides a prefabricated photovoltaic power transformer box-type foundation, including a box-type transformer compartment. An oil collection tank is provided on the outer wall of the box-type transformer compartment. A maintenance platform is provided on the outer wall of the box-type transformer compartment. Multiple supporting steel beams are fixedly connected to the bottom of the maintenance platform. The other end of each supporting steel beam is fixedly connected to the box-type transformer compartment. A pedestrian step is provided on the outer wall of the box-type transformer compartment. Two oil leakage holes are provided on the maintenance platform. Positioning holes are provided on the box-type transformer compartment. A first protective cover, which is a quarter circle, is fixedly connected to the outer wall of the box-type transformer compartment. A sliding groove is provided on the box-type transformer compartment. A first sliding rod is penetrating through the inner wall of the sliding groove. A ladder is fixedly fixed to the bottom of the first sliding rod. A rotating rod is fixedly connected to the outer wall of the ladder. A sleeve is penetrating through the outer wall of the rotating rod and fixedly connected to the box-type transformer compartment. Multiple crossbars are provided on the ladder. Limit grooves are provided on the outer wall of the crossbars. A support mechanism is penetrating through the crossbars. Through the cooperation of the first protective cover, the slide rail, and the first sliding rod, the ladder can only move in an arc. When the ladder is needed, it is moved to a vertical position, allowing the user to move up and down. When the ladder is needed or the internal movement space of the transformer substation needs to be increased, the ladder is moved from a vertical position to a horizontal position. When the ladder is moved to a horizontal position, it will move parallel to the inner wall of the transformer substation, thereby increasing the user's movement space inside the transformer substation. At the same time, the support mechanism supports the crossbar on the ladder, preventing the crossbar from swaying or tilting due to prolonged use, thus increasing the service life of the ladder and improving the safety of the user when using the ladder.

[0007] In a preferred embodiment of the present invention, the support mechanism includes an arc-shaped rod and a first sliding plate. Multiple arc-shaped rods are provided, and each arc-shaped rod is connected through the crossbar. A second sliding rod is fixedly connected to the top of the arc-shaped rod, and the second sliding rod is connected through the first sliding plate. A spring is provided at the bottom of the arc-shaped rod, and a slider is provided at the bottom of the spring. A second sliding plate is movably connected to the outer wall of the slider. Multiple slots are provided on the second sliding plate, and each slot is adapted to the slider. The first sliding rod is manually held and moved within the sliding groove. This movement of the first sliding rod drives the ladder, which is initially parallel to the inner wall of the transformer substation. After reaching the designated position, the ladder flips from a parallel to a vertical position. Simultaneously, the ladder's movement causes the curved rod to move. The second sliding rod, in conjunction with the first sliding plate, restricts the movement of the curved rod, ensuring it can only move along the inner wall of the first sliding plate. This guarantees that the curved rod and ladder will only move in an arc. As the slide reaches the appropriate position, the spring force pushes the slider downwards, allowing it to pass through the slot on the second slide plate. The cooperation between the slider and the slot restricts the arc-shaped rod, ensuring it remains in the designated position. This prevents the front end of the arc-shaped rod from deforming and becoming too weak to support the crossbar, thus preventing the user from stepping on the crossbar and hindering the use of the ladder. Once the user is inside the transformer compartment, the ladder can be retracted, changing it from a vertical to a horizontal position, ensuring it does not obstruct the user's movement inside the transformer compartment.

[0008] In a preferred embodiment of the present invention, a limiting block is fixedly connected to the outer wall of the arc-shaped rod, and the limiting block is adapted to the limiting groove. By setting the limiting block, while the arc-shaped rod is restricted in its movement by the slider and the groove, the limiting block also contacts the limiting groove. Through this contact, the surface of the crossbar is free of protrusions, preventing the user from slipping when stepping on the crossbar due to any protrusions.

[0009] In a preferred embodiment of the present invention, a third sliding rod is fixedly connected to the bottom of the ladder, and the third sliding rod is adapted to the positioning hole. By setting the third sliding rod, when the ladder moves to the designated position, the entire ladder will fall downwards. When the ladder falls downwards, the third sliding rod will contact the positioning hole. Through this contact, the entire ladder is restrained, preventing the ladder from swaying during use and thus affecting the user's ability to use the ladder.

[0010] In a preferred embodiment of the present invention, the outer wall of the crossbar is provided with anti-slip texture. The anti-slip texture on the crossbar increases the friction between the user and the crossbar when stepping on it, preventing slippage.

[0011] In a preferred embodiment of the present invention, a second protective cover is fixedly connected to the top of the first protective cover, and the first protective cover is relatively large. The first protective cover effectively shields the ladder at its base, reducing contact between the ladder and rainwater and thus extending its service life. Simultaneously, the second protective cover protects the first sliding rod, preventing accidental kicking and deformation by users walking along the edge of the transformer substation, which could affect its usability.

[0012] In a preferred embodiment of the present invention, the second protective cover is higher than the first sliding rod. The higher height of the second protective cover facilitates the upward movement of the first sliding rod, allowing the third sliding rod to separate from the positioning hole. Simultaneously, the upward movement of the first sliding rod separates the slot and the slider. After separation, when the user moves the ladder to reset, the slider will not affect the movement of the ladder.

[0013] In a preferred embodiment of the present invention, a foundation top surface embedded part is provided on the top of the transformer substation body, and multiple foundation top surface embedded parts are provided. The provision of foundation top surface embedded parts facilitates the subsequent welding of the transformer substation body to the prefabricated transformer compartment and the inverter prefabricated compartment base.

[0014] In a preferred embodiment of the present invention, the transformer substation housing is provided with a first cable hole, and there are multiple first cable holes. The transformer substation housing is also provided with a second cable hole, and there are multiple second cable holes. The diameters of the first cable holes and the second cable holes are different. The provision of the first and second cable holes facilitates the installation of cables.

[0015] In a preferred embodiment of the present invention, the oil collection tank is provided with an oil drain hole. The oil drain hole facilitates the drainage of oil from the oil collection tank.

[0016] The beneficial effects of this invention are as follows:

[0017] The prefabricated photovoltaic power box-type transformer foundation provided by this invention includes the following: 1. By manually holding the first sliding rod, the first sliding rod moves within a sliding groove. As the first sliding rod moves, it drives the ladder to move. Before moving, the ladder is parallel to the inner wall of the transformer compartment. After moving to the designated position, the ladder flips from a parallel position to a vertical position. Simultaneously, during the movement of the ladder, it drives the arc-shaped rod to move. Through the cooperation of the second sliding rod and the first sliding plate, the movement trajectory of the arc-shaped rod is restricted, ensuring that the arc-shaped rod can only move along the trajectory of the inner wall of the first sliding plate, thus ensuring that the arc-shaped rod and the ladder move only along the inner wall of the first sliding plate. It will move in an arc. When the ladder moves to the appropriate position, the spring force pushes the slider downward, so that the slider passes through the slot on the second slide. Through the cooperation of the slider and the slot, the arc rod is restricted, so that the arc rod can only be kept in the designated position. This ensures that the front end of the arc rod can be close to the crossbar, so as to avoid the crossbar from deforming and causing insufficient support, which would make it impossible to step on the crossbar and thus affect the user's use of the ladder. After the user is inside the transformer compartment, the ladder can be retracted, so that the ladder changes from a vertical position to a horizontal position, so that the ladder will not affect the user's movement inside the transformer compartment.

[0018] With the third sliding rod in place, when the ladder moves to the designated position, the entire ladder will drop downwards. As the ladder drops, the third sliding rod will contact the positioning hole. This contact will restrict the entire ladder and prevent it from swaying during use, thus affecting the user's ability to use the ladder.

[0019] The first protective cover shields the ladder at its base, reducing its contact with rainwater and extending its lifespan. Meanwhile, the second protective cover protects the first sliding rod, preventing users from accidentally kicking it while walking along the edge of the transformer compartment, which could deform the rod and affect its functionality.

Detailed Implementation

[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figure 1-9As shown in the embodiment, a prefabricated photovoltaic power box-type transformer foundation is provided, including a box-type transformer compartment 1. An oil collection tank 101 is provided on the outer wall of the box-type transformer compartment 1. A maintenance platform 102 is provided on the outer wall of the box-type transformer compartment 1. Supporting steel beams 103 are fixedly connected to the bottom of the maintenance platform 102. Multiple supporting steel beams 103 are provided, and the other end of each supporting steel beam 103 is fixedly connected to the box-type transformer compartment 1. A pedestrian step 104 is provided on the outer wall of the box-type transformer compartment 1. Two oil seepage holes 105 are provided on the maintenance platform 102. Positioning holes 106 are provided on the box-type transformer compartment 1. A first protective cover 107 is fixedly connected to the outer wall. The first protective cover 107 is a quarter circle. A slide groove 108 is provided on the transformer substation body 1. A first slide rod 109 is connected through the inner wall of the slide groove 108. A ladder 110 is fixedly connected to the bottom of the first slide rod 109. A rotating rod 111 is fixedly connected to the outer wall of the ladder 110. A sleeve 112 is connected through the outer wall of the rotating rod 111. The sleeve 112 is fixedly connected to the transformer substation body 1. A crossbar 113 is provided on the ladder 110. There are multiple crossbars 113. A limit groove 114 is provided on the outer wall of the crossbar 113. A support mechanism 2 is connected through the crossbar 113.

[0033] Reference Figure 6 and Figure 7The support mechanism 2 includes an arc-shaped rod 201 and a first sliding plate 202. Multiple arc-shaped rods 201 are provided. Each arc-shaped rod 201 is connected to a crossbar 113. A second sliding rod 203 is fixedly connected to the top of the arc-shaped rod 201 and is connected to the first sliding plate 202. A spring 204 is provided at the bottom of the arc-shaped rod 201, and a slider 205 is provided at the bottom of the spring 204. A second sliding plate 206 is movably connected to the outer wall of the slider 205. Multiple slots 207 are provided on the second sliding plate 206, and each slot 207 is adapted to the slider 205. When the first sliding rod 109 is manually held, the first sliding rod... The first slide rod 109 moves within the slide groove 108. When the first slide rod 109 moves, it drives the ladder 110 to move. Before the ladder 110 moves, it is parallel to the inner wall of the transformer substation 1. After the ladder 110 reaches the designated position, it flips from a parallel position to a vertical position. Simultaneously, during its movement, the ladder 110 drives the arc-shaped rod 201 to move. Through the cooperation of the second slide rod 203 and the first sliding plate 202, the movement trajectory of the arc-shaped rod 201 is restricted, ensuring that the arc-shaped rod 201 can only move along the trajectory of the inner wall of the first sliding plate 202, thus ensuring the proper functioning of the arc-shaped rod 201 and the ladder 110. The ladder 110 only moves in an arc. When the ladder 110 moves to the appropriate position, the spring force of the spring 204 pushes the slider 205 downward, causing the slider 205 to pass through the slot 207 on the second slide plate 206. Through the cooperation of the slider 205 and the slot 207, the arc-shaped rod 201 is restricted, ensuring that the arc-shaped rod 201 can only be kept in the designated position. This ensures that the front end of the arc-shaped rod 201 can be close to the crossbar 113, preventing the crossbar 113 from deforming and causing insufficient support, thus making the crossbar 113 unsteppable and affecting the user's use of the ladder 110. After the user is inside the transformer substation 1, the ladder 110 can be retracted. The ladder 110 is changed from a vertical position to a parallel position, so that the ladder 110 will not affect the user's movement inside the transformer compartment 1. The outer wall of the arc-shaped rod 201 is fixedly connected to the limiting block 208, which is adapted to the limiting groove 114. With the setting of the limiting block 208, when the arc-shaped rod 201 is restricted from moving by the slider 205 and the slot 207, the limiting block 208 will also contact the limiting groove 114. Through the contact between the two, there are no protrusions on the surface of the crossbar 113, which prevents the user from slipping when stepping on the crossbar 113 because of the protrusions.

[0034] Reference Figure 3 , Figure 4 , Figure 5 and Figure 8A third slide bar 115 is fixedly connected to the bottom of the ladder 110. The third slide bar 115 is adapted to the positioning hole 106. Using the third slide bar 115, when the ladder 110 moves to the designated position, the entire ladder 110 will fall downwards. When the ladder 110 falls downwards, the third slide bar 115 will contact the positioning hole 106. Through this contact, the ladder 110 is restrained, preventing it from swaying during use and thus affecting the user's ability to use the ladder. The outer wall of the crossbar 113 is provided with anti-slip textures. The anti-slip textures on the crossbar 113... To increase the friction between the user's foot and the crossbar 113 when stepping on it, preventing slippage; a second protective cover 116 is fixedly connected to the top of the first protective cover 107. The first protective cover 107 is larger in size, and its function is to completely cover the ladder 110 at the bottom of the first protective cover 107, reducing the contact between the ladder 110 and rainwater, thereby increasing the service life of the ladder 110. At the same time, the second protective cover 116 protects the first sliding bar 109, preventing the user from accidentally kicking the first sliding bar 109 when walking on the edge of the transformer compartment 1, causing the first sliding bar 109 to break. 09 deforms, thus affecting the use of the first slide rod 109; the second protective cover 116 is higher than the first slide rod 109. The higher height of the second protective cover 116 facilitates the upward movement of the first slide rod 109, allowing the third slide rod 115 to separate from the positioning hole 106. Simultaneously, the upward movement of the first slide rod 109 separates the slot 207 and the slider 205. After separation, when the user moves the ladder 110 to reset, the slider 205 will not affect the movement of the ladder 110; the top of the transformer substation 1 is equipped with a foundation top surface embedded part 117, and multiple foundation top surface embedded parts 117 are provided, utilizing… The embedded part 117 on the top surface of the foundation facilitates the subsequent welding of the transformer substation body 1 to the prefabricated transformer compartment and the inverter prefabricated compartment base. The transformer substation body 1 is provided with a first cable hole 118, and there are multiple first cable holes 118. The transformer substation body 1 is also provided with a second cable hole 119, and there are multiple second cable holes 119. The diameters of the first cable holes 118 and the second cable holes 119 are different. The first cable holes 118 and the second cable holes 119 are provided to facilitate the installation of cables. The oil collection tank 101 is provided with an oil drain hole 120, which facilitates the drainage of oil from the oil collection tank 101.

[0035] The first slide bar 109 is manually held, causing it to move within the slide groove 108. This movement of the first slide bar 109 drives the ladder 110 to move as well. Before moving, the ladder 110 is parallel to the inner wall of the transformer substation 1. After reaching the designated position, the ladder 110 flips from a parallel position to a vertical position. Simultaneously, the movement of the ladder 110 drives the curved rod 201. Through the cooperation of the second slide bar 203 and the first sliding plate 202, the movement trajectory of the curved rod 201 is restricted, ensuring that it can only move along the trajectory of the inner wall of the first sliding plate 202. This ensures that the curved rod 201 and the ladder 110 only move in an arc. As 110 moves to the appropriate position, the spring force of spring 204 pushes slider 205 downward, causing slider 205 to pass through the slot 207 on the second slide plate 206. Through the cooperation of slider 205 and slot 207, the arc-shaped rod 201 is restricted, ensuring that the arc-shaped rod 201 can only be kept in the designated position. This ensures that the front end of the arc-shaped rod 201 can be close to the crossbar 113, preventing the crossbar 113 from deforming and causing insufficient support, thus making the crossbar 113 unsteppable and affecting the user's use of ladder 110. When the user is inside the transformer substation 1, the ladder 110 can be retracted, changing the ladder 110 from a vertical position to a horizontal position, so that the ladder 110 will not affect the user's movement inside the transformer substation 1.
