Description

Technical Field

[0001] This application relates to the technical field of ring main units, and in particular to a ring main unit with an assembled body and base. Background Technology

[0002] A ring main unit is an outdoor box-type device used in power systems for ring network power supply. It is mainly used to achieve efficient power distribution and control and is widely used in urban power grids, residential areas and public facilities.

[0003] In related technologies, a ring main unit includes a box body and a base. The box body is welded to the base, and multiple electrical components are installed inside the box body.

[0004] Currently, the base and body of the ring main unit need to be fixed by welding first, and then multiple electrical components are installed on the base. Because the frame of the unit restricts the installation of electrical components, the process of installing electrical components is quite troublesome and requires a lot of time and effort. Utility Model Content

[0005] To address the issue of inconvenient installation of electrical components in ring main units, this application provides a ring main unit with an assembled enclosure and base.

[0006] This application provides a ring network box with an assembled body and base, which adopts the following technical solution:

[0007] A ring main unit with assembled enclosure and base includes an enclosure and a base. The enclosure contains multiple electrical components, and the enclosure has a mounting plate with a fixing structure for fixing the base and the mounting plate together.

[0008] By adopting the above technical solution, the staff first installs the electrical components on the base, and then operates the hoisting equipment to place the box on the base. The base and the box are fixed by the mounting plate. This makes it easier for the staff to install the electrical components first and then install the box, so as to prevent the box from interfering with the staff's installation of electrical components. This makes it easier to install the electrical components on the base, thereby improving the efficiency of installing the ring network box.

[0009] Optionally, the fixing structure includes a fastener and a fixing plate. The fixing plate is disposed on the mounting plate and has a fixing hole for the fastener to pass through. The base has a placement hole for the fastener to be inserted. When the fastener passes through the fixing hole and is inserted into the placement hole, the base and the mounting plate are fixed to each other.

[0010] By adopting the above technical solution, fasteners are inserted into the placement holes through the fixing holes, so that the mounting plate and the box can be fixed together by the fixing structure. Compared with welding, the fixing structure has the advantages of being detachable and flexible in installation. Workers can install electrical components first and then install the box, which provides convenience for workers to install ring network boxes.

[0011] Optionally, the base is provided with a guide groove, and the mounting plate is provided with a guide block. When the guide block is inserted into the guide groove, the fixing hole and the placement hole are aligned.

[0012] By adopting the above technical solution, when the staff fixes the box to the base, the fixing hole and the placement hole can be aligned by inserting the guide block into the guide groove. The staff does not need to spend time aligning the fixing hole and the placement hole, which is conducive to the staff passing the fastener through the fixing hole and inserting it into the placement hole, saving the staff the time of installing the box and the base, thereby improving the staff's installation efficiency.

[0013] Optionally, multiple mounting plates are provided, and each mounting plate is provided with a locking structure for fixing two adjacent mounting plates.

[0014] By adopting the above technical solution, two adjacent mounting plates are fixed by a locking structure, making the mounting plates standard parts. Manufacturers can mass-produce the mounting plates and then fix them together using the locking structure, thereby improving product production efficiency and saving manufacturers the production costs required for assembling ring network boxes.

[0015] Optionally, the locking structure includes a locking member and multiple locking pieces, which are disposed on different mounting plates. Each locking piece has a locking hole through which the locking member passes. When the locking member passes through the multiple locking holes, the locking member fixes the multiple locking pieces.

[0016] By adopting the above technical solution, when the locking component passes through multiple locking holes, the locking component can fix multiple locking pieces, so that multiple mounting plates can be fixed together by the locking structure, making the installation between mounting plates more flexible and convenient for workers to install.

[0017] Optionally, a placement groove is formed on the inner surface of the base, and the placement groove extends in a direction away from the ground; when the box is fixed on the base, the mounting plate is inserted into the placement groove.

[0018] By adopting the above technical solution, when the box is fixed on the base, the mounting plate is inserted into the placement groove, so that the groove wall of the placement groove acts as a block for the mounting plate, reducing the occurrence of the mounting plate shifting due to loose fasteners, making the fixation between the box and the base more reliable, and reducing the possibility of the box detaching from the base.

[0019] Optionally, the groove wall of the placement slot is provided with elastic protrusions, and the mounting plate is provided with grooves for the protrusions to be inserted. When the box is fixed on the base, the protrusions are inserted into the grooves and the protrusions deform.

[0020] By adopting the above technical solution, when the box is fixed on the base, the protrusion is inserted into the groove and deforms, so that the protrusion applies force to the mounting plate, making the mounting plate and the base fit together more tightly, thereby strengthening the connection between the mounting plate and the base.

[0021] Optionally, the fixing structure includes a limiting member, a limiting hole is provided on the bottom wall of the placement groove, and a receiving hole is provided on the mounting plate. When the limiting member passes through the limiting hole and is inserted into the receiving hole, the mounting plate and the base are fixed.

[0022] By adopting the above technical solution, the staff can insert the limiting member through the limiting hole into the receiving hole on the outer surface of the base to fix the base and the mounting plate. The staff does not need to open the box to operate on the inner surface of the base, which provides convenience for the staff to fix the base and the mounting plate.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Workers first install electrical components on the base, and then operate the hoisting equipment to place the enclosure on the base. The base and enclosure are fixed by the mounting plate, which makes it easier for workers to install electrical components first and then install the enclosure. This prevents the enclosure from interfering with the workers' installation of electrical components and makes it easier to install electrical components on the base, thereby improving the efficiency of installing the ring main unit.

[0025] 2. Fasteners are inserted into the mounting holes through the fixing holes, so that the mounting plate and the box can be fixed together by the fixing structure. Compared with welding, the fixing structure has the advantages of being detachable and flexible in installation. Workers can install electrical components first and then install the box, which makes it convenient for workers to install the ring network box. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0038] Example 1

[0039] This embodiment discloses a ring network box with an assembled body and base. (Refer to...) Figure 1 A ring network box with a housing 1 and a base 2 is assembled, including a housing 1 and a base 2, and multiple electrical components are fixedly connected inside the housing 1.

[0040] Reference Figure 1 and Figure 2The enclosure 1 has multiple mounting plates 3 on its surface near the ground. A first fixing plate 36 is integrally formed on each mounting plate 3. The first fixing plate 36 and the surface of the base 2 away from the ground are parallel to each other, and the first fixing plate 36 is perpendicular to the mounting plate 3. The first fixing plate 36 is welded to the surface of the enclosure 1 near the ground. A second fixing plate 37 is integrally formed on the surface of the first fixing plate 36 away from the ground, and the second fixing plate 37 is parallel to the mounting plate 3. The enclosure 1 includes a frame and multiple doors, all of which are rotatably connected to the frame. The second fixing plate 37 abuts against the inner surface of the doors.

[0041] Reference Figure 2 and Figure 3 The mounting plate 3 is provided with a locking structure 32, which includes two locking elements 321 and two locking pieces 322. The mounting plate 3 along the length direction of the base 2 is a longer mounting plate 3, and the mounting plate 3 along the width direction of the base 2 is a shorter mounting plate 3.

[0042] Reference Figure 3 and Figure 4 A retaining plate 38 is integrally formed on the longer mounting plate 3, perpendicular to both the longer mounting plate 3 and the first fixing plate 36. A locking piece 322 is integrally formed on the retaining plate 38, perpendicular to the retaining plate 38, and parallel to the longer mounting plate 3. Another locking piece 322 is integrally formed on the shorter mounting plate 3, perpendicular to both the shorter mounting plate 3 and the first fixing plate 36.

[0043] Reference Figure 3 and Figure 4 The locking element 321 is a bolt with a nut. The locking piece 322 has two locking holes 323 for the locking element 321 to pass through. The locking pieces 322 on two adjacent mounting plates 3 abut against each other, and the locking holes 323 are aligned one by one. The bolt passes through the locking holes 323, and the bolt and nut cooperate to fix the two adjacent mounting plates 3.

[0044] Reference Figure 4 and Figure 5 The mounting plate 3 is provided with multiple fixing structures 31, each including a fastener 311 and a fixing piece 312. The fastener 311 is a bolt. The fixing piece 312 is integrally formed on the mounting plate 3, perpendicular to the mounting plate 3 and perpendicular to the locking piece 322, and parallel to the first fixing plate 36.

[0045] Reference Figure 5 and Figure 6The fixing plate 312 has multiple fixing holes 313 for fasteners 311 to pass through. The base 2 has multiple placement holes 21 on its surface away from the ground for fasteners 311 to be inserted, and these placement holes 21 are aligned with their corresponding fixing holes 313. Both the fixing holes 313 and the placement holes 21 have internal threads on their inner surfaces, and the fasteners 311 are threaded into the fixing holes 313 and the placement holes 21.

[0046] Reference Figure 5 and Figure 6 When assembling the box 1 and the base 2, the workers first place the box 1 on the base 2 using hoisting equipment, and then insert bolts through the fixing holes 313 into the placement holes 21. Through the threaded connection, the base 2 and the mounting plate 3 are fixed to each other.

[0047] The implementation principle of Example 1 is as follows: the staff first installs multiple electrical components on the base 2, and then places the box 1 on the base 2 using hoisting equipment. At this time, the mounting plate 3 abuts against the base 2. The staff then inserts the fastener 311 through the fixing hole 313 into the placement hole 21 to fix the base 2 and the mounting plate 3 to each other.

[0048] Example 2

[0049] Reference Figure 7 and Figure 8 The difference between this embodiment and Embodiment 1 is that a placement groove 23 is formed on the inner surface of the base 2, extending circumferentially along the base 2 and penetrating in a direction away from the ground. An elastic protrusion 231 is fixedly connected to the bottom wall of the placement groove 23, surrounding the base 2 circumferentially. A groove 34 for inserting the protrusion 231 is formed on the outer surface of the mounting plate 3, penetrating in the length direction of the mounting plate 3.

[0050] Reference Figure 8 When the housing 1 is fixed on the base 2, the mounting plate 3 is inserted into the placement groove 23, and the outer surface of the mounting plate 3 abuts against the bottom wall of the placement groove 23. At this time, the protrusion 231 is inserted into the groove 34, and the protrusion 231 deforms.

[0051] Reference Figure 7 and Figure 8 A guide groove 22 is provided on the surface of the placement groove 23 near the ground. A guide block 33 is fixedly connected to the surface of the mounting plate 3 away from the box body 1.

[0052] Reference Figure 8 When the guide block 33 is inserted into the guide groove 22, the fixing hole 313 is aligned with the placement hole 21 so that the worker can insert the fastener 311 through the fixing hole 313 into the placement hole 21.

[0053] The implementation principle of Example 2 is as follows: After the staff installs the electrical components on the base 2, the box 1 is placed on the base 2 by the hoisting equipment. At this time, the fixing hole 313 is aligned with the placement hole 21. The staff inserts the fastener 311 through the fixing hole 313 into the placement hole 21. The mounting plate 3 and the base 2 are fixed by the threaded connection.

[0054] Example 3

[0055] Reference Figure 9 and Figure 10 The difference between this embodiment and embodiment 2 is that the fixing structure 31 includes a limiting member, which is a bolt. A limiting hole 24 is formed on the outer surface of the base 2, and the limiting hole 24 penetrates the bottom wall of the placement groove 23. A receiving hole 35 is formed on the outer surface of the mounting plate 3. Both the limiting hole 24 and the receiving hole 35 have internal threads, allowing the limiting member to pass through the limiting hole 24 and be inserted into the receiving hole 35. When the limiting member passes through the limiting hole 24 and is inserted into the receiving hole, the mounting plate 3 and the base 2 are fixed to each other through a threaded connection.

[0056] Reference Figure 10 When the guide block 33 is inserted into the guide groove 22, the receiving hole 35 is aligned with the limiting hole 24, so that the operator can insert the limiting member through the limiting hole 24 into the receiving hole 35.

[0057] The implementation principle of Example 3 is as follows: After the staff installs the electrical components on the base 2, the box 1 is placed on the base 2 by the hoisting equipment. At this time, the limiting hole 24 and the receiving hole 35 are aligned. The staff inserts the limiting piece through the limiting hole 24 into the receiving hole from the outer surface of the base 2. The mounting plate 3 and the base 2 are fixed by the threaded connection.
