Description

Technical Field

[0001] The utility model relates to the technical field of installation of reactive power compensation devices, in particular to a reactive power compensation device additionally installed on a charging pile. Background Art

[0002] The reactive power compensator is a compensation device. Its role in the electronic power supply system is to improve the power factor of the power grid, reduce the loss of the power supply transformer and transmission lines, improve the power supply efficiency, and improve the power supply environment.

[0003] The patent with announcement number CN209786540U discloses a reactive compensation device box for electric vehicle charging piles, which includes: a maintenance door, a base plate and a support column. The maintenance door consists of a bottom inspection door and a top inspection door, and the bottom inspection door is connected to the top inspection door through a rotating shaft. Four support columns with the same structure are vertically arranged above the base plate, wherein the support columns on the left and right sides are connected with cross beams through threaded components, and the cross beams are cross-connected with vertical mounting plates through bolt components. A horizontal fixing frame is installed between the two vertical mounting plates, and a group of mouse guards are arranged above the base plate, and the two ends of each mouse guard are respectively vertically connected to the two support columns.

[0004] In the prior art such as the above-mentioned patent, the reactive compensation device is usually arranged separately or built into the charging pile when the charging pile is produced. However, for the charging piles that lack reactive compensation devices in the early days, it is required to add reactive compensation devices. There is currently a lack of solutions for adding reactive compensation devices to charging piles, and the existing reactive compensation devices are not convenient for disassembly, assembly and maintenance. Utility Model Content

[0005] The purpose of the utility model is to provide a reactive power compensation device installed on a charging pile to solve the deficiencies in the above-mentioned prior art.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a reactive compensation device installed on a charging pile, comprising a reactive compensator and an installation cabinet fixedly connected to one side of the charging pile, the back side of the installation cabinet having an opening, the opening being connected to a window opened on the charging pile, a cabinet door being hinged on the installation cabinet, the reactive compensator being fixedly installed on the inner side of the cabinet door, the inner side of the cabinet door being vertically slidably connected to a wire row, the wire row being located below the reactive compensator, and a locking assembly being provided between the wire row and the reactive compensator for locking the two together.

[0007] Furthermore, the locking assembly includes a connecting rod, which is fixedly connected to the line row, and a vertical rod is fixedly connected to the connecting rod. The top of the vertical rod is rotatably connected to a cross rod. When the line row slides up to abut against the reactive compensator, the cross rod is rotated to engage with the reactive compensator. When the lock needs to be released, it only needs to be rotated so that the cross rod cannot abut against the reactive compensator to release the lock.

[0008] Furthermore, a lock is provided between the installation cabinet and the cabinet door, and the lock allows the reactive power compensator to be stably placed in the installation cabinet after the cabinet door is closed.

[0009] Furthermore, two vertical sliding grooves are provided on the cabinet door, and two sliding blocks are fixedly connected to the cable row. The two sliding blocks are slidably connected to the two sliding grooves in a one-to-one correspondence, so as to realize the vertical sliding of the cable row relative to the cabinet door.

[0010] Furthermore, a handle is provided on the cabinet door, and the handle facilitates the worker to open the cabinet door from the installation cabinet.

[0011] Furthermore, a rain shield is provided on the top of the installation cabinet, and reinforcing ribs are provided between the installation cabinet and the charging pile. The rain shield can allow falling rainwater to slide down the slope of the rain shield to the ground to prevent water accumulation on the top of the installation cabinet. The reinforcing ribs can further strengthen the connection between the installation cabinet and the charging pile.

[0012] In the above technical scheme, the utility model provides a reactive compensation device for a charging pile, in which the reactive compensator is installed on the cabinet door. When the cabinet door is closed, a part of the reactive compensator extends into the interior of the charging pile and the other part of the reactive compensator is wrapped by the installation cabinet. At this time, the structure for installing the reactive compensator is more compact, which solves the problem that the internal space of the traditional charging pile is too small to fully accommodate the reactive compensator. The distance between the wire row and the reactive compensator can be changed by the sliding connection between the wire row and the cabinet door. When the reactive compensator is in working state, the wire row can be abutted against the bottom of the reactive compensator to reduce the space occupied by the charging pile and the internal space of the installation cabinet. When the reactive compensator needs to be inspected and repaired, the locking component is released so that the wire row slides down away from the reactive compensator due to gravity, thereby expanding the distance between the two, leaving more space for inspecting the reactive compensator, thereby further increasing the practicality of the device.

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] See also Figure 1-4 The utility model provides a reactive power compensation device for a charging pile, comprising a reactive power compensator 1 and a mounting cabinet 3 fixedly connected to one side of the charging pile 2. The back side of the mounting cabinet 3 has an opening, which is communicated with a window provided on the charging pile 2. A cabinet door 4 is hingedly connected to the mounting cabinet 3. The reactive power compensator 1 is fixedly mounted on the inner side of the cabinet door 4. A wire row 5 is vertically slidably connected to the inner side of the cabinet door 4. The wire row 5 is located below the reactive power compensator 1. A locking assembly capable of locking the two together is provided between the wire row 5 and the reactive power compensator 1. The mounting cabinet 3 is fixedly mounted on the charging pile 2 by means of a steel plate and bolts, etc. The reactive power compensator 1 is mounted on the cabinet door 4. When the cabinet door 4 is closed, a part of the reactive power compensator 1 extends into the interior of the charging pile 2. The other part of the reactive compensator 1 is wrapped by the installation cabinet 3. At this time, the installation structure of the reactive compensator 1 is more compact, which solves the problem that the internal space of the traditional charging pile 2 is too small to fully accommodate the reactive compensator 1. Before the reactive compensator 1 starts working, it is necessary to slide the wire row 5 so that the wire row 5 abuts against the bottom of the reactive compensator 1 and then fix the two together through a locking component. Then, the reactive compensator 1 and the wire row 5 are placed on the charging pile 2 and the installation cabinet 3 to reduce the internal space occupied by the two. When the reactive compensator 1 needs to be inspected and repaired, the cabinet door 4 is opened first and then locked by the contact locking component. The wire row 5 will slide away from the reactive compensator 1 relative to the cabinet door 4, leaving enough space for convenient inspection of the reactive compensator 1.

[0022] In the above technical scheme, the utility model provides a reactive compensation device for a charging pile, in which the reactive compensator 1 is installed on the cabinet door 4. When the cabinet door 4 is closed, a part of the reactive compensator 1 extends into the charging pile 2 and the other part of the reactive compensator 1 is wrapped by the installation cabinet 3. At this time, the installation structure of the reactive compensator 1 is more compact, which solves the problem that the internal space of the traditional charging pile 2 is too small to fully accommodate the reactive compensator 1. The distance between the wire row 5 and the reactive compensator 1 can be changed by the sliding connection between the wire row 5 and the cabinet door 4. When the reactive compensator 1 is in working state, the wire row 5 can be abutted against the bottom of the reactive compensator 1 to reduce the space occupied by the charging pile 2 and the internal space of the installation cabinet 3. When the reactive compensator 1 needs to be inspected and repaired, the locking component is released so that the wire row 5 slides down away from the reactive compensator 1 due to gravity, thereby expanding the distance between the two, leaving more space for inspecting the reactive compensator 1, thereby further increasing the practicality of the device.

A vertical rod 61 is fixedly connected to the connecting rod 6, and a cross rod 611 is rotatably connected to the top of the vertical rod 61. When the line row 5 slides up to abut against the reactive compensator 1, the cross rod 611 is rotated to engage with the reactive compensator 1. When the lock needs to be released, it only needs to be rotated so that the cross rod 611 cannot abut against the reactive compensator 1 to release the lock.

[0024] As a preferred technical solution of this embodiment, a lock is provided between the installation cabinet 3 and the cabinet door 4, so that the reactive power compensator 1 can be stably placed in the installation cabinet 3 after the cabinet door 4 is closed by the lock.

[0025] As a preferred technical solution of this embodiment, two vertical sliding grooves 41 are opened on the cabinet door 4, and two sliding blocks 51 are fixedly connected to the wire row 5. The two sliding blocks 51 are slidingly connected to the two sliding grooves 41 in a one-to-one correspondence, so as to realize the vertical sliding of the wire row 5 relative to the cabinet door 4.

[0026] In the preferred technical solution of this embodiment, a handle 42 is provided on the cabinet door 4 , and the handle 42 facilitates the worker to open the cabinet door 4 from the installation cabinet 3 .

[0027] As the preferred technical solution of this embodiment, a rain shield 31 is provided on the top of the installation cabinet 3, and a reinforcing rib 7 is provided between the installation cabinet 3 and the charging pile 2. The rain shield 31 can allow the falling rainwater to slide along the slope of the rain shield 31 to the ground to prevent water accumulation on the top of the installation cabinet 3. The reinforcing rib 7 can further strengthen the connection between the installation cabinet 3 and the charging pile 2.

[0028] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
