Description

Technical Field

[0001] This utility model relates to the field of prefabricated ring network box technology, specifically a prefabricated ring network box. Background Technology

[0002] A prefabricated ring main unit is a pre-manufactured, highly integrated ring main power supply device that integrates switching equipment, protection devices, and control systems into a single enclosure to form an independent power distribution unit. This type of equipment is easy to install, debug, and maintain, and greatly improves the operating efficiency of the power system.

[0003] In the prior art, such as the pre-installed closed ring mesh box proposed in patent application number "CN202222065562.7", the height of the partition can be adjusted by adjusting the adjustment mechanism, thereby adjusting the internal space of the box. It is convenient and quick to use. Through the setting of spring, moving groove and moving block, the card slot and card block can be quickly disengaged, thereby facilitating the repositioning of the partition.

[0004] In the prior art, prefabricated ring main units are often equipped with a hinged top cover for easy maintenance. When maintenance is needed, the top cover can be directly lifted to inspect the inside of the unit. However, lifting the top cover is not only labor-intensive, but also exposes all the electrical components inside the unit to the outside in rainy weather, making them susceptible to damage from rainwater and affecting the normal operation of the prefabricated ring main unit. Utility Model Content

[0005] The purpose of this utility model is to provide a pre-installed ring network box to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A prefabricated ring network box includes a box body, a base fixedly installed on the bottom surface of the box body, two doors connected by hinges near the front surface of the box body, a movable body movably inserted into the upper surface of the box body, a roof fixedly connected to the upper surface of the movable body, a protective mechanism provided on the bottom surface of the roof, fixed frames fixedly installed on both inner side walls of the box body, reciprocating screws rotatably connected inside the two fixed frames, a movable block sleeved on the outside of the reciprocating screws, and one end of the movable block fixedly connected to the movable body;

[0008] The protective mechanism includes a storage compartment, inside which a winding shaft is rotatably connected, and a flexible curtain is wound around the outside of the winding shaft, with a connecting plate fixedly connected to one end of the flexible curtain.

[0009] Preferably, a motor is installed on the upper end of each of the two fixed frames, and the output ends of the two motors are respectively connected to one end of the two reciprocating lead screws, and a knob is fixedly connected to one end of the winding shaft.

[0010] Preferably, two L-shaped support plates are fixedly installed on the outer wall of the storage compartment.

[0015] The beneficial effects of this utility model are:

[0016] 1. In this utility model, when the prefabricated ring network box needs to be inspected, after opening the box door, there is no need to lift the roof. The motors installed on the two fixed frames drive the two reciprocating screws to rotate simultaneously. With the help of the movable block, the movable body can be moved upward, and the roof can be moved upward, so that there is enough maintenance space in the upper part of the box for the staff to carry out maintenance operations inside the box. Due to the roof, there is enough space in the top of the box, and the heads of the maintenance personnel can be shielded from rain. The flexible curtain can further shield the maintenance personnel from getting wet in the rain, and can also shield one side of the prefabricated ring network box to prevent rainwater from splashing into the box and causing dampness inside the box.

[0017] 2. The present invention is equipped with a base, which can raise the box body and prevent water accumulation from causing dampness at the bottom of the box body. Moreover, if water enters the base, it can be discharged from the various drain pipes along the slope of the water guide slope due to the water guide slope, and finally discharged through the various drainage hoses, thus preventing water from accumulating on the ground where the prefabricated ring network box is located and being unable to be discharged.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] A pre-assembled ring main unit, such as Figures 1-8As shown, the device includes a box body 1, a base 4 fixedly installed on the bottom surface of the box body 1, two doors 3 connected by hinges near the front surface of the box body 1, a movable body 5 movably inserted into the upper surface of the box body 1, a canopy 2 fixedly connected to the upper surface of the movable body 5, a protective mechanism provided on the bottom surface of the canopy 2, fixed frames 6 fixedly installed on both inner side walls of the box body 1, reciprocating screws 7 rotatably connected inside the two fixed frames 6, movable blocks 8 sleeved on the outside of the reciprocating screws 7, and one end of the movable blocks 8 fixedly connected to the movable body 5, the protective mechanism including a storage compartment 9, a winding shaft 14 rotatably connected inside the storage compartment 9, a flexible curtain 10 wound around the outside of the winding shaft 14, and a connecting plate 15 fixedly connected to one end of the flexible curtain 10.

[0031] Motors are installed on the upper ends of the two fixed frames 6, and the output ends of the two motors are respectively connected to one end of the two reciprocating screws 7. A knob 11 is fixedly connected to one end of the winding shaft 14. The motor model is HG-KR. The inner wall of the movable block 8 and the reciprocating screw 7 is provided with a thread that matches the reciprocating screw 7. When the reciprocating screw 7 rotates, under the cooperation of the thread and the limitation of the fixed frame 6, the movable block 8 can be driven to move up and down along the outside of the reciprocating screw 7.

[0032] Two L-shaped support plates 13 are fixedly installed on the outer wall of the storage compartment 9. A fixing rod 12 is inserted into the outer wall of each L-shaped support plate 13. An annular plate 20 is fixedly connected to the outer wall of each fixing rod 12. A return spring is sleeved on the outside of the fixing rod 12 and located between the annular plate 20 and the inner wall of the L-shaped support plate 13. Two fixing holes are opened on the outer wall of the storage compartment 9. One end of the fixing rod 12 passes through the knob 11 and is movably installed inside the fixing hole. The fixing hole and one end of the fixing rod 12 fit together. Under the action of the return spring, one end of the fixing rod 12 can be driven to re-insert into the fixing hole to fix the position of the knob 11.

[0033] When the prefabricated ring main unit needs maintenance, after opening the door 3, there is no need to lift the roof 2. The motors mounted on the two fixed frames 6 simultaneously drive the two reciprocating screws 7 to rotate, causing the two movable blocks 8 to move upwards along the screws 7 within the fixed frames 6. This moves the movable body 5 upwards, and consequently, the roof 2 upwards, away from the unit 1, leaving sufficient maintenance space at the top of the unit 1 for personnel to perform internal maintenance. Furthermore, the roof 2 provides sufficient space at the top of the unit 1 for further maintenance. At the same time, it can also shield the heads of maintenance personnel from rain. By pulling the two fixed rods 12 away from the L-shaped support plate 13, the return spring is compressed and contracted, so that one end of the two fixed rods 12 can be removed from the fixed hole, which can release the fixation of the knob 11. At this time, the connecting plate 15 can be pulled, so that the flexible curtain 10 rolled on the winding shaft 14 can be unfurled, which can further shield the maintenance personnel from rain and prevent them from getting wet. It can also shield one side of the pre-installed ring network box to prevent rainwater from splashing into the box and causing dampness inside the box.

[0034] After maintenance, by turning the knob 11, the winding shaft 14 can be rotated to wind up the flexible curtain 10. Then, the fixing rod 12 is released, and under the action of the return spring, one end of the fixing rod 12 can be re-inserted into the fixing hole to fix the position of the knob 11, thereby fixing the position of the winding shaft 14 and completing the storage of the flexible curtain 10.

[0035] A filter screen 19 is fixedly installed inside the base 4 near both ends. A water guide slope 16 is fixedly installed inside the base 4. Several drain pipes 17 are fixedly connected to the bottom surface of the base 4 near both sides. Drain hoses 18 are fixedly connected to the bottom of the drain pipes 17. One-way valves are installed on the outer walls of the drain pipes 17. The drain pipes 17 are evenly distributed. By setting one-way valves, external water can be prevented from entering the drain pipes 17 through the drain hoses 18, so that the drain pipes 17 have good one-way drainage performance.

[0036] Specifically, when there is rain and water accumulates on the bottom of the prefabricated ring network box, the base 4 can raise the box body 1, preventing the water from making the bottom of the box body 1 wet. The water enters the base 4, and due to the drainage slope 16, the water can be discharged from the drain pipes 17 along the slope of the drainage slope 16, and finally discharged through the drain hoses 18, preventing water from accumulating on the ground where the prefabricated ring network box is located and being unable to be discharged. The filter screen 19 can block dirt in the water, preventing it from entering the base 4 and clogging the drain pipes 17.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
