[0002] Low-voltage compensation cabinets are currently widely used, so when installing reactive compensation cabinets, you need to choose according to the place of use. If it needs to be installed near the transformer, the reactive compensation cabinet must have a rainproof function. Its main function is to improve the power factor and improve the power utilization rate. Most of the high-power equipment used in daily life uses inductive current. Some components in the equipment play a major role, but other components will also run. The reactive compensation cabinet will reduce the so-called reactive current to the minimum range.

[0003] For example, the Chinese patent with publication number CN107749571A discloses a low-voltage reactive power compensation cabinet, wherein the upper end surface of the base is provided with a plurality of support tubes along its circumferential direction, and an elastic member is provided inside the support tubes, and a plurality of latches matching the support tubes are provided on the side wall of the cabinet, and the plurality of latches are detachably plugged into the corresponding support tubes and contact the elastic member so that the cabinet is elastically and detachably fixed on the base; one end of the support column is fixed to the outer top of the cabinet, and the other end is fixed to the canopy; an electrical room and an operating room are arranged from left to right inside the cabinet, and a bearing mechanism capable of being lifted and lowered in the vertical direction is provided inside the electrical room, and a control mechanism connected to the bearing mechanism and capable of controlling the lifting and lowering of the bearing mechanism is provided inside the operating room. The low-voltage reactive power compensation cabinet can be installed, disassembled and repaired without the aid of auxiliary tools, and can also be convenient for heavier main electrical components, and can also block rain and have a good shock absorption effect.

[0004] The above patent has the following problems:

[0005] This patent has some shortcomings when used. For example, although the above solution solves the shock absorption, rain protection and disassembly and assembly effects of conventional reactive compensation cabinets, it is not suitable for the plain area in the lower reaches of the Yellow River.

Every time the rainy season comes, it will cause excessive water accumulation in the urban area. Although the above solution can resist rainwater from above, it cannot autonomously prevent water accumulation from below. In view of this, we propose a reactive compensation cabinet.

These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0026] The reactive power compensation cabinet disclosed in the embodiment of the present application includes a cabinet body 1, a closing mechanism 2 is arranged inside the cabinet body 1, a floating block 3 is fixedly connected to the bottom surface of the cabinet body 1, a sliding rod 4 is slidably connected to the inner wall of the floating block 3, a fixed seat 5 is slidably connected to the outer surface of the sliding rod 4, the outer surface of the fixed seat 5 is fixedly connected to the outer surface of the cabinet body 1, a hollow mechanism 6 is arranged below the sliding rod 4, and a counterweight mechanism 7 is arranged at the top of the sliding rod 4.

[0027] Based on the above structure, the float 3 has a strong buoyancy in the water. When the float 3 is submerged in the accumulated water, it will push the cabinet 1 to move upward along the sliding direction provided by the slide rod 4. The closing mechanism 2 can extend the extended rain shield 701 during maintenance, thereby reducing the probability of rainwater entering the cabinet 1 when the operators are repairing. The hollow mechanism 6 can reduce its own contact with the accumulated water before it is submerged in the water, while reducing its own weight and preventing the soles of the operators from slipping during the repair. The counterweight mechanism 7 can form a form similar to a balance with the cabinet 1, so that the float 3 can push the cabinet 1 more sensitively and keep the cabinet 1 away from the accumulated water on the ground.

[0028] In one embodiment, the closing mechanism 2 includes a slide 201, the outer surface of the slide 201 is fixedly connected to the inner wall of the cabinet 1, the bottom surface of the slide 201 is fixedly connected to a partition 202, the outer surface of the partition 202 is fixedly connected to the inner wall of the cabinet 1, and the bottom surface of the partition 202 is rotatably connected to a cabinet door 203.

[0029] Specifically, the slideway 201 is located at the outer edges of both sides of the partition 202, so that a gap for expansion and contraction can be vacated between the slideway 201 and the partition 202.

[0030] In this embodiment, a moisture-proof agent is installed inside the partition 202, and a layer of waterproof cloth strips are covered on the outside. At the same time, waterproof cloth strips are also attached to the edges of the cabinet door 203, thereby preventing rainwater from seeping in through the gaps on the edges of the cabinet door 203 when the cabinet door 203 is closed.

[0035] Specifically, the outer surface of the threaded rod 603 is provided with a threaded blade, so that the friction between the threaded rod 603 and the inside of the ground is increased after the threaded rod 603 is driven into the ground, thereby enabling the threaded rod 603 to have a good grip.

[0036] In this embodiment, after the threaded rod 603 is driven into the inner wall of the fixing plate 602 and the ground, the entire device can have good wind and wave resistance when it is affected by waves caused by accumulated water.

[0037] In one embodiment, a flight column 604 is fixedly connected to the outer surface of the load-bearing plate 601, and a load-bearing platform 605 is fixedly connected to the flight column 604 at one end away from the load-bearing plate 601.

[0042] In this embodiment, the rain shield 701 can shield rainwater from above and guide rainwater away from the cabinet 1 through the inclined surfaces at both ends.

[0043] In one embodiment, the bottom surface of the rain shield 701 is fixedly connected to a sliding rod 2 706, the bottom end of the sliding rod 2 706 is fixedly connected to the outer surface of the load-bearing plate 601, the outer surface of the sliding rod 2 706 is slidably connected to a counterweight block 707, the outer surface of the counterweight block 707 is fixedly connected to a steel cable 708, the steel cable 708 is fixedly connected to the outer surface of the cabinet 1 at the end away from the counterweight block 707, and the outer surface of the steel cable 708 is in close contact with the outer surfaces of the roller 1 703 and the roller 2 705.

[0044] Specifically, the interior of the counterweight block 707 is hollow, and tap water can be added into the interior according to the actual total weight of the cabinet 1 , so that the weight of the counterweight block 707 is slightly smaller than the weight of the cabinet 1 .

[0045] In this embodiment, the weight of the counterweight block 707 can be slightly smaller than the weight of the cabinet 1, so that when water accumulates, the float can more accurately lift the cabinet 1 away from the water surface according to the depth of the water.

[0046] When the reactive power compensation cabinet of this embodiment is in use, the threaded rod 603 is first driven into the ground through the inner wall of the threaded rod 603, and then tap water is added to the inside of the counterweight block 707 according to the actual weight of the cabinet 1, so that the weight of the counterweight block 707 can be slightly less than the total weight of the cabinet 1. When emergency repair or maintenance is needed, the operator can step on the hollow plate 607 and open the cabinet door 203. When the cabinet door 203 is opened, it can slide on the inner wall of the groove 206 through the positioning rod 204 to push the telescopic plate 205 out. When the depth of the accumulated water submerges to one-half of the floating block 3, the floating plate will float up and push the cabinet 1 upward, so that the cabinet 1 can be away from the accumulated water from the bottom.
