Description

Technical Field

[0001] The utility model belongs to the technical field of converter cabinets, and in particular relates to a dehumidification box structure used for a converter cabinet. Background Art

[0002] As the core component of electric locomotives, the converter cabinet undertakes the important task of converting the grid energy into a series of energy to drive the traction motor. The converter cabinet is also developing towards a highly integrated direction.

[0003] To ensure dryness inside the converter cabinet, the current approach is to place an independently packaged dehumidification box directly into the converter cabinet to absorb moisture through the calcium chloride inside. However, over long periods of use, this independently packaged dehumidification box may crack at the bottom of the shell due to the moisture-absorbing calcium chloride, causing water to spill into the converter cabinet and damage the electrical components inside. Therefore, this approach has significant limitations in actual use and leaves room for improvement. Utility Model Content

[0004] The purpose of the utility model is to provide a dehumidification box structure for a converter cabinet, so as to solve the problem of water leakage caused by the bottom rupture of the existing independently packaged dehumidification box in long-term use proposed in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dehumidification box structure for a converter cabinet, comprising a placement box with a through hole on its side; a mesh cover with upper and lower openings, a bottom end of which is installed in an internal position of the placement box, and a gap is left between the mesh cover and the inner wall of the placement box; a water collecting box is arranged outside the side of the placement box with the through hole, and the side of the water collecting box opposite to the placement box is also provided with a through hole; a guide pipe, one end of which is fixedly connected to the through hole on the placement box, and the other end is connected through the through hole on the water collecting box, and a blocking assembly is installed at the end of the guide pipe, wherein the guide pipe is connected through the cabinet body. In use, calcium chloride is placed in the mesh cover. When the calcium chloride absorbs moisture and turns into water, it is discharged from the mesh cover into the placement box. Then the placement box discharges the water into the water collecting box through the guide pipe, thereby completing the collection of water and achieving the conversion from inside to outside the converter cabinet.

[0006] Preferably, an inclined portion is formed at the bottom end of the inner portion of the guide tube, and the inclined portion gradually tilts downward from the direction of the placement box toward the direction of the water collection box, thereby realizing rapid drainage of water in the placement box.

[0007] Preferably, the sealing assembly includes a fixed plate installed on the top of the other end of the guide tube, which can be connected by bonding or welding in actual use, and a check plate arranged at intervals just below the fixed plate. A film is bonded between the fixed plate and the check plate. When water flows through, the check plate will be pushed open to achieve drainage. When no water flows through, the check plate will close and seal the end of the guide tube under the action of the gravity of its own mass, thereby preventing moisture from flowing back from the outside and the water collection box.

[0008] Preferably, the fixing plate and the check plate are located at the same center of a circle, and their outer diameters are equal to the outer diameter of the guide tube, so that the guide tube can be completely blocked without affecting the normal installation of the guide tube and the water collecting box.

[0009] Preferably, the outer surface of the guide tube is provided with a thread, and a limiting nut and a connecting nut are sleeved on the threaded area of ​​the guide tube, wherein the limiting nut is abutted against the inner wall of the water collecting box to achieve the connection between the water collecting box and the guide tube. At the same time, during long-term use, the water collecting box can be disassembled and the water collected inside can be poured out, and the connecting nut is abutted against the outer surface of the cabinet to achieve the installation of the placement box and the mesh cover.

[0010] Preferably, the two ends of the film are arc-shaped, and the horizontal projection of the film partially overlaps with the outer diameter of the guide tube, so that the fixing plate, the check plate, and the film form a structure that completely overlaps with the end of the guide tube in the projected state, thereby achieving the blocking of the guide tube.

[0011] Preferably, the through hole on the water collecting box is located at the top of the water collecting box, and the bottom end surface of the water collecting box is lower than the bottom end surface of the placement box, so as to achieve better collection of the discharged water.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] Through the design of the utility model, the calcium chloride that absorbs moisture and turns into water can be directly and quickly discharged from the converter cabinet to the outside of the converter cabinet, thereby avoiding damage to the electrical components inside the converter cabinet caused by water seepage, and solving the shortcomings of the existing independently packaged dehumidification boxes in use. At the same time, the dehumidification box of the utility model can also prevent the backflow of humid gas. The whole device has a simple structure, is convenient for processing and production, and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
