Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to an outdoor waterproof power distribution cabinet. Background Art

[0002] The power distribution cabinet is a general term for the motor control center, which is the final equipment of the power distribution system and is mainly used for integrated control of the circuit. When using, some power distribution cabinets usually need to be directly installed outdoors. In order to overcome the impact of high temperature weather on substation equipment, air outlets are usually set on the outer wall of the power distribution cabinet for heat dissipation. At the same time, such a setting also causes rainwater to easily flow into the ventilation holes of the power distribution cabinet from the upper end when rainy weather occurs. Therefore, it is necessary to waterproof the outdoor power distribution cabinet to improve the safety of the use of the power distribution cabinet.

[0003] For example, an outdoor waterproof distribution cabinet with application number CN202222722895.2 includes a distribution cabinet body, a ceiling mechanism, a pointed roof, a water collecting box, a filter, a drain pipe and a cabinet door. Rainwater will fall on the pointed roof, and then the pointed roof can divert the rainwater into the water collecting box, and then the drain pipe can divert the rainwater outward, which can prevent rainwater from flowing on the surface of the distribution cabinet body, prevent rainwater from corroding the distribution cabinet body, and prevent rainwater from seeping into the distribution cabinet body. The filter can filter rainwater when in use to prevent debris from entering the water collecting box.

[0004] When the water collecting box proposed in the above patent is in use, rainwater falls through the pointed roof and is introduced into the inner cavity of the water collecting box for storage. The filter net fixedly installed on the upper end of the water collecting box is used to filter out debris. Since the filter net is fixedly installed on the upper end of the water collecting box, such a setting causes smaller impurities to fall into the water collecting box through the filter net. Long-term accumulation can easily cause the drainage outlet inside the water collecting box to be blocked.

[0005] Therefore, we propose an outdoor waterproof distribution cabinet to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide an outdoor waterproof distribution cabinet to solve the problem proposed in the above background technology that since the filter screen is fixedly installed on the upper end of the water collecting box, such an arrangement causes smaller impurities to fall into the water collecting box through the filter screen, and long-term accumulation can easily cause the drainage outlet inside the water collecting box to be blocked.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an outdoor waterproof power distribution cabinet, comprising a power distribution cabinet body and a vent opened on one side of the outer wall of the power distribution cabinet body, a water collection component is fixedly installed on the upper end of the power distribution cabinet body, and water guide pipes are fixedly installed at the four corners of the lower end of the inner cavity of the water collection component, and filter components are respectively installed around the upper end of the water collection component through fixed components, the filter components are suitable for filtering impurities on the upper end of the water collection component, and the fixed components are used to install the filter components on the upper end of the water collection component;

[0008] The fixing assembly comprises a locking mechanism and a rotating mechanism threadedly connected in the inner cavity of the upper end of the locking mechanism, and the locking mechanism is embedded and installed around the upper end of the water collecting assembly.

[0009] Preferably, the water collecting assembly comprises an annular block and a water collecting annular groove formed at the upper end of the annular block.

[0010] Preferably, the locking mechanism comprises a fixed round block and a circular screw groove opened in the middle of the upper end of the fixed round block, a hollow barrel is fixedly installed on the lower end of the fixed round block, and fan-shaped clamps are fixedly installed in a circular shape at equal intervals on the upper end of the inner cavity bottom surface of the hollow barrel.

[0011] Preferably, the rotating mechanism comprises a hollow round block and an externally threaded round tube fixedly mounted on the lower end of the hollow round block, and expansion blocks are fixedly mounted around the lower end of the externally threaded round tube.

[0012] Preferably, the filter assembly includes a first filter mechanism and a docking rod fixedly mounted around the lower end of the first filter mechanism, an embedded filter screen plate is fixedly mounted on the lower end of the docking rod, and the embedded filter screen plate is movably mounted in the inner cavity of the water collecting ring groove.

[0013] Preferably, the first filtering mechanism comprises a pressing plate and a filtering mesh layer embedded in the upper end of the pressing plate, and round rods are fixedly mounted on the four corners of the lower end of the pressing plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The operator inserts the round rods on the four corners of the lower end of the pressing plate into the inner cavities of the hollow round block, the externally threaded round tube, the expansion block, the circular screw groove and the hollow round barrel. By rotating the externally threaded round tube threadedly connected in the inner cavity of the circular screw groove, the expansion block is moved from the upper end of the outer wall of the fan-shaped clamping blocks arranged at equal intervals in a circular ring to the lower end of the outer wall. The outer wall of the fan-shaped clamping blocks arranged at equal intervals in a circular ring is clamped by the expansion block to fix the position of the round rod. Such an arrangement makes it convenient for the operator to rotate the hollow round block in the opposite direction to drive the externally threaded round tube to move up when there are many impurities at the upper end of the filter assembly. The round rod is loosened in the opposite way to the above process. By installing and disassembling the filter assembly, the operator can clean the filter assembly conveniently and improve the cleanliness of the water collection ring groove.

[0016] 2. Since the lower end of the pressure plate is fixedly installed by the docking rod and the embedded filter screen plate, the embedded filter screen plate fixedly installed at the lower end of the pressure plate is placed in the inner cavity of the water collecting ring groove. The double-layer filtration of the filter screen layer and the embedded filter screen plate improves the cleanliness of rainwater entering the inner cavity of the water collecting ring groove.

The filter component 6 is suitable for filtering impurities on the upper end of the water collecting component 3. The fixed component 5 is used to install the filter component 6 on the upper end of the water collecting component 3.

[0025] The fixing assembly 5 comprises a locking mechanism 51 and a rotating mechanism 52 threadedly connected to an inner cavity at an upper end of the locking mechanism 51 . The locking mechanism 51 is embedded and installed around the upper end of the water collecting assembly 3 .

[0026] The locking mechanism 51 includes a fixed round block 511 and a round screw groove 512 opened in the middle of the upper end of the fixed round block 511. A hollow barrel 513 is fixedly installed at the lower end of the fixed round block 511. Fan-shaped clamping blocks 514 are fixedly installed in an annular shape at equal intervals on the upper end of the inner cavity bottom surface of the hollow barrel 513.

[0027] The rotating mechanism 52 comprises a hollow round block 521 and an externally threaded round tube 522 fixedly mounted on the lower end of the hollow round block 521 , and an expansion block 523 is fixedly mounted around the lower end of the externally threaded round tube 522 .

[0028] In this embodiment, the operator places the pressing plate 611 on the upper end of the water collecting ring groove 32, so that the round rods 613 on the four corners of the lower end of the pressing plate 611 are inserted into the inner cavities of the hollow round block 521, the externally threaded round tube 522, the expansion block 523, the circular screw groove 512 and the hollow barrel 513. After the round rod 613 is continuously inserted to the bottom of the hollow barrel 513, the operator rotates the externally threaded round tube 522 threadedly connected to the inner cavity of the circular screw groove 512, so that the externally threaded round tube 522 drives the expansion block 523 to move downward, thereby causing the expansion block 523 to move from the upper end of the outer wall of the fan-shaped clamping blocks 514 arranged at equal intervals in a circular ring shape. Move to the lower end of the outer wall, clamp the outer wall of the fan-shaped clamping block 514 arranged at equal intervals in a circular ring through the expansion block 523, and the lower end of the round rod 613 is arranged in the inner cavity of the fan-shaped clamping block 514 arranged at equal intervals in a circular ring, so that the position of the round rod 613 can be fixed. Such an arrangement can be convenient for the operator to rotate the hollow round block 521 in the opposite direction to the above process when there are many impurities at the upper end of the filter component 6, so as to loosen the round rod 613. By installing and disassembling the filter component 6, the operator can clean the filter component 6 and improve the cleanliness of the water collecting ring groove 32.

[0029] Example 2

[0030] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 2The water collecting assembly 3 includes an annular block 31 and a water collecting annular groove 32 opened at the upper end of the annular block 31 .

[0031] The filter assembly 6 includes a first filter mechanism 61 and a docking rod 62 fixedly installed around the lower end of the first filter mechanism 61. An embedded filter mesh plate 63 is fixedly installed at the lower end of the docking rod 62. The embedded filter mesh plate 63 is movably installed in the inner cavity of the water collecting ring groove 32. The mesh opening diameter of the filter mesh layer 612 is set to be larger than the mesh opening diameter of the filter mesh layer 612. Mesh openings of different sizes are set to filter impurities of different sizes.

[0032] The first filtering mechanism 61 includes a pressing plate 611 and a filtering mesh layer 612 embedded in the upper end of the pressing plate 611. Round rods 613 are fixedly installed at the four corners of the lower end of the pressing plate 611. The lower end of the round rod 613 is movably installed in the inner cavity of the hollow round block 521, the externally threaded round tube 522, the expansion block 523, the round screw groove 512 and the hollow round barrel 513.

[0033] In this embodiment: since the lower end of the pressure plate 611 is fixedly installed by the docking rod 62 and the embedded filter screen plate 63, the operator can place the embedded filter screen plate 63 fixedly installed at the lower end of the pressure plate 611 into the inner cavity of the water collecting ring groove 32 when placing the pressure plate 611. Through the double-layer filtration of the filter screen layer 612 and the embedded filter screen plate 63, the cleanliness of rainwater entering the inner cavity of the water collecting ring groove 32 is improved.

[0034] Working principle: The operator places the pressing plate 611 on the upper end of the water collecting ring groove 32, so that the round rods 613 on the four corners of the lower end of the pressing plate 611 are inserted into the inner cavities of the hollow round block 521, the externally threaded round tube 522, the expansion block 523, the circular screw groove 512 and the hollow barrel 513, and then the round rod 613 is continuously inserted to the bottom of the hollow barrel 513. The operator rotates the externally threaded round tube 522 threadedly connected to the inner cavity of the circular screw groove 512, so that the externally threaded round tube 522 drives the expansion block 523 to move downward, thereby moving the expansion block 523 from the upper end of the outer wall where the fan-shaped clamping blocks 514 are arranged at equal intervals in a circular shape to the lower end of the outer wall. The outer wall of the fan-shaped clamp block 514 arranged at equal intervals in a circular ring shape is clamped by the expansion block 523, and the lower end of the round rod 613 is arranged in the inner cavity of the fan-shaped clamp block 514 arranged at equal intervals in a circular ring shape, so that the position of the round rod 613 can be fixed. Since the lower end of the pressure plate 611 is fixedly installed by the docking rod 62 and the embedded filter mesh plate 63, the operator can place the embedded filter mesh plate 63 fixedly installed at the lower end of the pressure plate 611 into the inner cavity of the water collecting ring groove 32 when placing the pressure plate 611. Rainwater can directly pass through the double-layer filtration of the filter mesh layer 612 and the embedded filter mesh plate 63 and enter the inner cavity of the water collecting ring groove 32.
