Description

Technical Field

[0001] This utility model relates to the field of European-style box-type substations, and more specifically, to a side sliding door structure for a European-style box-type substation. Background Technology

[0002] A prefabricated substation, also known as a prefabricated transformer substation, is a type of high-voltage switchgear, distribution transformer, and low-voltage power distribution device. Prefabricated substations are suitable for mines, factories, oil and gas fields, and wind power stations. They replace the original civil engineering power distribution rooms and substations, becoming a new type of complete set of power distribution equipment.

[0003] Existing European-style prefabricated substation doors are generally double-opening via hinges. However, the double-opening doors of European-style prefabricated substations are limited by the hinges and cannot be fully opened. In addition, when the substation equipment is moved into the European-style enclosure, some parts of the door need to be manually limited to prevent it from rebounding and becoming an obstruction. Furthermore, the door has limited space for forward extension. Therefore, we propose a side-sliding door structure for European-style prefabricated substations to solve the above-mentioned problems. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a side sliding door structure for a European-style prefabricated substation. This structure solves the problems of existing European-style prefabricated substation double doors being limited by hinges and unable to open fully; the need for manual restraint of some doors when moving equipment into the European-style enclosure to prevent rebound and obstruction; and the limited forward extension space of the doors. Therefore, we propose a side sliding door structure for a European-style prefabricated substation to solve the above-mentioned problems.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A sliding door structure for a European-style box-type substation includes a European-style box body and a box door. The top of the European-style box body is fixedly connected to a box top, and the bottom of the box top is fixedly connected to a sliding groove. The sliding groove is U-shaped and located on the outer side of the top of the European-style box body. The box door has two doors, and the top of the doors facing each other is movably connected to a pulley, which is slidably connected inside the sliding groove. A deformable retractable mechanism is movably connected to the center of the rear end of the European-style box body. Rectangular slots are opened on both sides of the European-style box body, and a pop-up reset mechanism is fixedly connected inside each rectangular slot.

[0009] Furthermore, the deformable winding mechanism includes a reel, steel cables, a connecting shaft, a control motor, sprockets, and a chain. The steel cables are provided in two strands and are axially symmetrically wound around the outside of the reel. The connecting shaft is fixedly connected to the center of one end of the reel. The sprockets are provided in two strands and are connected by chain drive. The output end of the control motor is fixedly connected to the center of one of the sprockets.

[0010] Furthermore, a protective frame is fixedly connected to the outside of the control motor, and the protective frame, control motor and sprocket are all located inside the European-style housing. The protective frame is fixedly connected to the top rear side of the inside of the European-style housing.

[0011] Furthermore, the winding reel is located at the rear center of the European-style housing, and the end of the connecting shaft away from the winding reel passes through and is fixedly connected to the center of another sprocket shaft. The connection between the connecting shaft and the European-style housing is movably connected by a bearing.

[0012] Furthermore, the European-style box body has limit holes at both ends of the rear side, and slots are provided on both sides of the European-style box body. The slots pass through the rectangular slots laterally and intersect with the limit holes. The end of the steel cable away from the winding reel passes through the limit holes and is fixedly connected to the back side of the box door. The steel cable is compatible with the slots.

[0013] Furthermore, the pop-up reset mechanism includes a fixed shaft, a reset spring, a sliding ring, a drive bar, and a pop-up block. The drive bar is movably connected to both sides of the pop-up block via a rotating shaft, and the sliding ring is movably connected to the other end of the drive bar via a rotating shaft. The sliding ring is slidably connected to the outside of the fixed shaft, and the reset spring is sleeved on both ends of the fixed shaft.

[0014] Furthermore, the two ends of the fixed shaft are respectively fixedly connected to the two ends of the inner side of the rectangular groove. The surface of the pop-up block is provided with an arc-shaped groove, and the arc-shaped groove is adapted to the slot. The side of the pop-up block away from the arc-shaped groove is recessed inward, and the curvature of the recess is adapted to the fixed shaft.

[0015] 3. Beneficial Effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] This solution utilizes a control motor that drives a chain to simultaneously rotate a sprocket and its output end along the same trajectory. The connecting shaft, driven by the sprocket, rotates a winding roller, winding and tightening a steel cable. This cable pulls the door open in accordance with the desired size. During this process, the steel cable pops out from the slot, forming a triangle with the door and the European-style enclosure. When the pulley slides to the corner of the groove, the steel cable pulls one end of the door to fold towards both sides of the European-style enclosure, making it parallel and close to the outside of the enclosure. This facilitates the door's sliding opening to both sides, preventing the double-door design with hinged transmission from obstructing the movement of electrical equipment into the enclosure. Furthermore, it reduces the forward extension space of the door, improving the convenience of later maintenance and inspection of the European-style prefabricated substation.

[0018] This design utilizes the inward compression of the pop-up block during the parallel clamping process of the cabinet door. At this time, the drive bar is forcefully pushed outward to push the sliding ring towards both ends of the fixed shaft. Subsequently, the return spring is compressed and contracted. When the cabinet door needs to be reset, the control motor controls the steel cable to release. At this time, the reaction force of the return spring moves the sliding ring to the opposite side, thereby pushing the pop-up block upward to lift the cabinet door back to a parallel state at the opening of the European-style cabinet. This facilitates the automatic reset of the cabinet door to the side-sliding open state, making subsequent closing operations convenient. Attached Figure Description

[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example 1:

[0028] Please see Figures 1-5 A sliding door structure for a European-style box-type substation includes a European-style box body 1 and a box door 3. The top of the European-style box body 1 is fixedly connected to a box top 2, and the bottom of the box top 2 is fixedly connected to a sliding groove 4. The sliding groove 4 is U-shaped and located on the outer side of the top of the European-style box body 1. The box door 3 has two doors, and the top of the side of the box door 3 that is close to each other is movably connected to a pulley 5, and the pulley 5 is slidably connected to the inside of the sliding groove 4. The center of the rear end of the European-style box body 1 is movably connected to a deformable retraction mechanism 6. Rectangular grooves 7 are opened on both sides of the European-style box body 1, and a pop-up reset mechanism 8 is fixedly connected inside the rectangular grooves 7.

[0029] Example 2:

[0030] In view of the above embodiment 1, further description is provided, see reference. Figure 1 , Figure 3 and Figure 4 The deformable retractable mechanism 6 includes a reel 601, steel cables 602, a connecting shaft 603, a control motor 604, sprockets 605, and a chain 606. Two steel cables 602 are symmetrically wound around the outside of the reel 601. The connecting shaft 603 is fixedly connected to the center of one end of the reel 601. Two sprockets 605 are connected via the chain 606. The output end of the control motor 604 is fixedly connected to the center of one of the sprockets 605. A protective frame 9 is fixedly connected to the outside of the control motor 604. The protective frame 9, the control motor 604, and the sprockets 605 are all located inside the European-style housing 1. The frame 9 is fixedly connected to the top rear side of the interior of the European-style box 1. The winding reel 601 is located at the center of the rear side of the European-style box 1. The end of the connecting shaft 603 away from the winding reel 601 passes through and is fixedly connected to the shaft of another sprocket 605. The connection between the connecting shaft 603 and the European-style box 1 is movably connected by a bearing. Limiting holes are opened at both ends of the rear side of the European-style box 1. The two sides of the European-style box 1 are provided with slots 10. The slots 10 pass through the rectangular slots 7 laterally and intersect with the limiting holes. The end of the steel cable 602 away from the winding reel 601 passes through the limiting holes and is fixedly connected to the back side of the box door 3. The steel cable 602 is compatible with the slots 10.

[0031] By controlling the motor 604, the chain 606 simultaneously drives the sprocket 605 to rotate along the same trajectory as its output end. Subsequently, the connecting shaft 603 is driven by the sprocket 605 to drive the winding roller to rotate, winding and tightening the steel cable 602, so that it is pulled in accordance with the opening size of the box door 3. During this process, the steel cable 602 will pop out from the slot 10 to form a triangle with the box door 3 and the European-style box 1 until the pulley 5 slides to the corner of the slide groove 4. The steel cable 602 pulls one end of the box door 3 to fold towards both sides of the European-style box 1, so that it is parallel and close to the outside of the European-style box 1. This facilitates the sliding opening of the box door 3 to both sides, and avoids the double door with the transmission hinge from obstructing the movement of the substation equipment into the European-style box 1 after it is opened to both sides. Secondly, it reduces the forward extension space of the box door 3 and improves the convenience of later maintenance and inspection of the European-style box substation.

[0032] Example 3:

[0033] In view of the above embodiments 1 and 2, further description is provided, please refer to... Figure 1 , Figure 3 and Figure 5 The pop-up reset mechanism 8 includes a fixed shaft 801, a reset spring 802, a sliding ring 803, a drive bar 804, and a pop-up block 805. The drive bar 804 is movably connected to both sides of the pop-up block 805 via a rotating shaft, and the sliding ring 803 is movably connected to the other end of the drive bar 804 via a rotating shaft. The sliding ring 803 is slidably connected to the outside of the fixed shaft 801, and the reset spring 802 is sleeved on both ends of the fixed shaft 801. Both ends of the fixed shaft 801 are fixedly connected to the inner ends of the rectangular groove 7. The surface of the pop-up block 805 is provided with an arc-shaped groove 11, and the arc-shaped groove 11 is adapted to the slot 10. The side of the pop-up block 805 away from the arc-shaped groove 11 is recessed inward, and the curvature of the recess is adapted to the fixed shaft 801.

[0034] As the door 3 is pressed inward during the parallel clamping process, the pop-up block 805 is squeezed inward. At this time, the drive bar 804 is forced to push the sliding ring 803 outward to slide towards both ends of the fixed shaft 801. Then, the return spring 802 is compressed and contracted. When the door 3 needs to be reset, the control motor 604 controls the steel cable 602 to be released. At this time, the reaction force of the return spring 802 moves the sliding ring 803 to the opposite side, thereby pushing the pop-up block 805 upward to lift the door 3 and reset it to the parallel state at the opening of the European-style box body 1. This facilitates the automatic reset of the door 3 to the side-sliding open state, making it convenient for subsequent closing operations.

[0035] Based on the above embodiments 1, 2, and 3, the working principle is further described below. In use, the door 3 is pushed open to both sides. At this time, the pulley 5 slides inside the slide groove 4. Simultaneously, the control motor 604 is started, driving the sprocket 605 to rotate along the same trajectory as its output end via the chain 606. Subsequently, the connecting shaft 603, driven by the sprocket 605, drives the winding roller to rotate, winding and tightening the steel cable 602, causing it to pull in accordance with the opening size of the door 3. During this process, the steel cable 602 will pop out from inside the slot 10, forming a triangle with the door 3 and the European-style box body 1, until the pulley 5 slides to the corner of the slide groove 4. When the steel cable 602 pulls one end of the box door 3 to fold towards both sides of the European-style box body 1, making it parallel and close to the outside of the European-style box body 1, the box door 3 is pressed inward to squeeze the pop-up block 805 during the parallel and close process. At this time, the drive bar 804 is forced to push the sliding ring 803 outward to slide towards both ends of the fixed shaft 801. Then, the return spring 802 is compressed and contracted. When the box door 3 needs to be reset, the control motor 604 controls the steel cable 602 to be released. At this time, the reaction force of the return spring 802 moves the sliding ring 803 to the opposite side, thereby pushing the pop-up block 805 upward to lift the box door 3 and reset it to a parallel state at the opening of the European-style box body 1.

[0036] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
