Description

Technical Field

[0001] The utility model relates to the field of power distribution cabinets, and more specifically to an adjustable power distribution cabinet. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet, which is the terminal equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is generally installed outdoors. Since most of the components in the distribution cabinet are electrical appliances, the outdoor distribution cabinet needs to have rainproof function. The common rainproof measure for distribution cabinets is to install a downward extending rain shield on the top of the distribution cabinet. This rain shield is fixed and has a fixed size. When maintenance personnel need to inspect the distribution cabinet, they cannot adjust the extended length of the rain shield according to the usage. For example, if the rain shield is extended too long, it is easy to interfere with the maintenance personnel's head, which brings inconvenience to the work. Utility Model Content

[0003] The utility model provides an adjustable power distribution cabinet, which can adjust the extension length of the shielding cloth according to actual use conditions.

[0004] An adjustable power distribution cabinet comprises a cabinet body, a cabinet door is rotatably connected to the cabinet body, a rotating shaft is rotatably connected to the upper end of the cabinet body, a coil spring is fixedly connected between the rotating shaft and the outer wall of the cabinet body, a shielding cloth is fixedly connected to the rotating shaft, a sleeve is fixedly connected to one end of the shielding cloth, and a plurality of positioning rods are fixedly connected to the cabinet door, and the heights of the plurality of positioning rods are all lower than the height of the rotating shaft.

[0005] The upper end of the cabinet is fixedly connected with a storage box, and the rotating shaft is located in the storage box.

[0006] A limiting block is fixedly connected inside the storage box.

[0007] A brush is fixedly connected to the bottom of the limiting block. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] See also Figure 3-5 ,

[0014] An adjustable power distribution cabinet comprises a cabinet body 101, a cabinet door 201 is rotatably connected to the cabinet body 101, a rotating shaft 303 is rotatably connected to the upper end of the cabinet body 101 via a bearing, a coil spring is fixedly connected between the rotating shaft 303 and the outer wall of the cabinet body 101, a shielding cloth 304 is bonded to the rotating shaft 303, one end of the shielding cloth 304 is fixedly connected to a sleeve 305 via stitches, and a plurality of positioning rods 202 are welded and fixedly connected to the cabinet door 201.

[0015] When using the power distribution cabinet, the maintenance personnel open the cabinet door 201 to a state perpendicular to the cabinet body 101, and then they can inspect the electrical components in the cabinet body 101. The shielding cloth 304 is in a rolled-up state under the action of the coil spring. When performing maintenance, the maintenance personnel can pull the sleeve 305 outward, and the sleeve 305 drives the shielding cloth 304 to extend. At the same time, the shielding cloth 304 drives the rotating shaft 303 to rotate, and the coil spring is forced to curl. The sleeve 305 is put on one of the positioning rods 202 to achieve the positioning of the shielding cloth 304. At this time, the shielding cloth 304 is in an extended state, and then the shielding cloth 304 can play the role of sunshade or rainproof, which is convenient for maintenance personnel to inspect the electrical components inside the power distribution cabinet in high temperature or rainy weather. At the same time, it can also prevent rainwater from entering the power distribution cabinet during maintenance and causing damage to the electrical components. When the shielding cloth 304 is loosened, the shielding cloth 304 is automatically rolled up under the action of the coil spring.

[0016] Multiple positioning rods 202 can all realize the positioning of the shielding cloth 304. By selecting positioning rods 202 at different positions to fix the shielding cloth 304, the extended length of the shielding cloth 304 can be adjusted, which is convenient for the staff to adjust according to actual needs. For example, under the premise that the shielding cloth 304 blocks rain in light rain weather, in order to prevent the shielding cloth 304 from interfering with the head of the maintenance personnel, it can be shortened appropriately.

[0017] Since the heights of the plurality of positioning rods 202 are all lower than the height of the rotating shaft 303 , the shielding cloth 304 is always in an inclined state when in the extended state, thereby facilitating the downward diversion of rainwater and preventing rainwater from accumulating on the shielding cloth 304 .

[0018] See also Figure 4-5 ,

[0019] The upper end of the cabinet 101 is fixedly connected with a storage box 301 by bolts, and the rotating shaft 303 is located in the storage box 301 .

[0020] The storage box 301 is used to shield the shielding cloth 304 to prevent irrelevant personnel from damaging it.

[0021] See also Figure 4 ,

[0022] The storage box 301 is fixedly connected with a limit block 302 by bolts.

[0023] The limit block 302 serves to limit the sleeve 305. When the shielding cloth 304 is rolled up, the limit block 302 can be tightly attached to the surface of the shielding cloth 304, thereby ensuring that the surface of the shielding cloth 304 is flat. When the shielding cloth 304 is rolled up, the sleeve 305 is automatically stuck on the limit block 302, making it convenient for the maintenance personnel to manually pull out the sleeve 305 next time.

[0024] See also Figure 3 ,

[0025] A brush is fixedly connected to the bottom of the limiting block 302 by bolts, and the brush can remove debris on the surface of the shielding cloth 304 to prevent the shielding cloth 304 from being affected in its retraction.

[0026] See also Figure 4 ,

[0027] A plurality of ventilation slots 102 are provided on both sides of the cabinet 101 .

[0028] The plurality of ventilation slots 102 play a role in ventilation, and can ensure air circulation inside and outside the cabinet 101, thereby achieving the function of heat dissipation.

[0029] See also Figure 5 ,

[0030] A shielding plate 103 is disposed above each ventilation slot 102 , and the shielding plate 103 is welded to the outer wall of the cabinet 101 .

[0031] The shielding plate 103 is used to shield the ventilation slot 102 to prevent foreign matter from entering the cabinet 101 through the ventilation slot 102 .

[0032] See also Figure 5 ,

[0033] Two mounting frames 104 are welded inside the cabinet 101 , and a plurality of threaded holes are formed on the two mounting frames 104 .

[0034] The electrical components are mounted on the two mounting frames 104 by means of bolts, so that the height positions of the electrical components can be adjusted and the electrical components can be reasonably arranged.

[0035] See also Figure 5 ,

[0036] The cabinet door 201 is rotationally connected to the cabinet body 101 via a damping shaft, which can increase the rotational friction between the cabinet door 201 and the cabinet body 101, thereby ensuring that the cabinet door 201 is opened to a state perpendicular to the cabinet body 101 and preventing it from rotating at will due to external force.

[0037] See also Figure 3 ,

[0038] The cabinet door 201 is fixedly connected with a limit plate 105 by means of bolts. When the cabinet door 201 is opened to a state perpendicular to the cabinet body 101 , the limit plate 105 can block the cabinet door 201 to prevent it from further rotating.

[0039] See also Figure 1 ,

[0040] The shielding cloth 304 is made of polyester, and the shielding cloth 304 made of polyester has good waterproof performance.
