Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a single-phase contactless voltage stabilizing device. Background Technique

[0002] Voltage, as an important evaluation index to measure the quality of electric energy, is a basic condition to ensure power supply services. Power enterprises attach great importance to the low voltage problem. Especially, rural power grids are characterized by numerous points, long lines, wide areas, scattered loads and concentrated power consumption, resulting in rural low voltage becoming a long-term and dynamic systematic problem. The randomness, seasonality and periodicity of rural power consumption loads are obvious. As a whole, the power consumption load rate is low, the peak-valley difference is large, and the annual average load rate is low. The low voltage problem is prominent during peak power consumption periods, causing some household appliances to be unable to be used normally, which has an impact on the social image and service quality of power enterprises.

[0003] An existing single-phase contactless voltage stabilizing device (publication number: CN214204525U) has at least the following drawbacks: The above device can protect the voltage stabilizer by setting foam aluminum plates on the outer wall of the voltage stabilizer. However, since the foam aluminum plates are a separate installation structure and the outer shell of the voltage stabilizer is also a separate installation structure, when the staff needs to repair the voltage stabilizer, it is necessary to disassemble the foam aluminum plates and the outer shell of the voltage stabilizer separately. The disassembly is cumbersome and the disassembly speed is slow, affecting the maintenance efficiency of the voltage stabilizer. Therefore, this utility model is proposed. Content of the Utility Model

[0004] The purpose of this utility model is to solve the defects existing in the prior art, and a single-phase contactless voltage stabilizing device is proposed.

[0005] In order to achieve the above purpose, this utility model adopts the following technical scheme:

[0006] A single-phase contactless voltage stabilizing device includes a voltage stabilizer main body. A top cover is arranged on the top surface of the voltage stabilizer main body. A protective shell is fixed to the outer wall of the top cover. The protective shell is an aluminum hollow plate, and buffer foam is filled inside the protective shell. A disassembly and assembly component is arranged inside the voltage stabilizer main body. The disassembly and assembly component includes fixing strips fixed on the left and right sides of the voltage stabilizer main body. Sliding grooves are opened on the top surfaces of the fixing strips. Two sliding strips are fixed to the bottom surface of the protective shell, and the sliding strips are slidably arranged inside the sliding grooves.

[0007] As a further solution of the present utility model, three locking holes are provided on both the left and right sides of the voltage regulator main body. A locking rod is inserted into the interior of the locking hole. An inclined groove is provided on the outer wall of the locking rod. One end of the locking rod is slidably inserted into the interior of the top cover and one side of the protective shell. A fixed block is fixed on the front side inside the voltage regulator main body. One end of the locking rod is fixed with a resilient rod. A spring is sleeved on the outer wall of the resilient rod. One end of the resilient rod is slidably inserted into one side of the fixed block. An unlocking frame is slidably arranged on the front side of the voltage regulator main body. A plurality of sliding plates are arranged on the rear side of the unlocking frame. The sliding plates of the unlocking frame are in contact with the top plate of the inclined groove.

[0008] As a further solution of the present utility model, a limiting rod is provided on the rear side of the protective shell, and the limiting rod is also fixed to the rear end of the sliding strip.

[0009] As a further solution of the present utility model, directional wheels are fixed near both the left and right sides of the bottom surface of the limiting rod. The bottom ends of the directional wheels are on the same horizontal plane as the bottom ends of the universal wheels of the voltage regulator main body.

[0010] As a further solution of the present utility model, rubber strips are fixed near both the front and rear sides of the top surface of the voltage regulator main body. The rubber strips are in close contact with the top inner wall surface of the top cover.

[0011] As a further solution of the present utility model, a first pull rod is fixed on the front side of the unlocking frame, and a second pull rod is fixed on the top surface of the protective shell.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] By providing the protective shell, it can play a protective role for the voltage regulator main body. Utilizing the aluminum material of the protective shell can conduct the heat of the top cover, increasing the heat dissipation effect of the voltage regulator main body. When it is necessary to repair the voltage regulator main body, the locking rod can be separated from the top cover and the protective shell through the unlocking frame to unlock the top cover and the protective shell. Subsequently, the top cover and the protective shell can be directly slid to repair the voltage regulator main body. The disassembly process is simple and convenient, without the need to disassemble the top cover and the protective shell separately, increasing the repair efficiency of the voltage regulator main body.

[0023] Such as Figures 1-4As shown in the figure, a single-phase contactless voltage stabilizer device includes a voltage stabilizer main body 1. A top cover 101 is provided on the top surface of the voltage stabilizer main body 1. A protective shell 102 is fixed to the outer wall of the top cover 101. The protective shell 102 is an aluminum hollow plate, and the inside of the protective shell 102 is filled with buffer foam. A disassembly and assembly component is provided inside the voltage stabilizer main body 1. The disassembly and assembly component includes fixing bars 2 fixed to the left and right sides of the voltage stabilizer main body 1. A sliding groove 201 is formed on the top surface of the fixing bar 2. Two sliding bars 202 are fixed to the bottom surface of the protective shell 102, and the sliding bars 202 are slidably arranged inside the sliding groove 201.

[0024] As Figures 2-4 shown in the figure, in this embodiment, three locking holes 203 are provided on both the left and right sides of the voltage stabilizer main body 1. A locking rod 204 is inserted into the locking hole 203. An inclined groove 208 is formed on the outer wall of the locking rod 204. One end of the locking rod 204 is slidably inserted into the inside of the top cover 101 and one side of the protective shell 102. A fixing block 205 is fixed to the front side inside the voltage stabilizer main body 1. One end of the locking rod 204 is fixed with a return spring rod 206. A spring is sleeved on the outer wall of the return spring rod 206. One end of the return spring rod 206 is slidably inserted into one side of the fixing block 205. An unlocking frame 207 is slidably arranged on the front side of the voltage stabilizer main body 1. A plurality of sliding plates are arranged on the rear side of the unlocking frame 207, and the sliding plates of the unlocking frame 207 are in contact with the top plate of the inclined groove 208.

[0025] As Figures 2-4 shown in the figure, in this embodiment, a limiting rod 3 is provided on the rear side of the protective shell 102, and the limiting rod 3 is also fixed to the rear end of the sliding bar 202.

[0026] As Figures 2-4 shown in the figure, in this embodiment, a directional wheel 301 is fixed to the bottom surface of the limiting rod 3 near both the left and right sides. The bottom end of the directional wheel 301 is on the same horizontal plane as the bottom end of the universal wheel of the voltage stabilizer main body 1.

[0027] As Figures 2-4 shown in the figure, in this embodiment, rubber strips 4 are fixed to the top surface of the voltage stabilizer main body 1 near both the front and rear sides, and the rubber strips 4 are in close contact with the top inner wall surface of the top cover 101.

[0028] As Figures 2-4 shown in the figure, in this embodiment, a first pull rod 5 is fixed to the front side of the unlocking frame 207, and a second pull rod 501 is fixed to the top surface of the protective shell 102.

[0029] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: During use, hold the first pull rod 5 with one hand and slide the unlocking frame 207 downward, so that the sliding plate of the unlocking frame 207 abuts against the top plate of the inclined groove 208, causing the locking rod 204 to move inwardly into the voltage regulator main body 1 under force. At this time, the locking rod 204 is separated from the top cover 101 and the protective shell 102. During this process, the elastic return rod 206 slides on one side of the fixed block 205 and compresses the spring. Subsequently, the staff holds the second pull rod 501 with the other hand and pushes it, causing the top cover 101 and the protective shell 102 to slide on the voltage regulator main body 1. At this time, the sliding strip 202 slides inside the sliding groove 201, thereby disassembling the top cover 101 and the protective shell 102, facilitating the staff to repair the voltage regulator main body 1. The limiting rod 3 can play a role in positioning and limiting the sliding of the top cover 101 and the protective shell 102, facilitating the staff to better snap and install the top cover 101 and the protective shell 102 with the voltage regulator main body 1 when installing the top cover 101 and the protective shell 102. By providing the guiding wheels 301, it can support the rear ends of the top cover 101 and the protective shell 102 when sliding and disassembling the top cover 101 and the protective shell 102, preventing the rear ends of the top cover 101 and the protective shell 102 from moving downward without support, resulting in the sliding of the sliding strip 202 inside the sliding groove 201 being restricted and affecting the disassembly efficiency of the top cover 101 and the protective shell 102. By providing the rubber strip 4, after the top cover 101 is installed, the rubber strip 4 tightly abuts against the top surface of the inner wall of the top cover 101, which can prevent a gap from remaining between the top cover 101 and the voltage regulator main body 1, so that abnormal noises are generated when the voltage regulator main body 1 vibrates or dust enters the inside of the voltage regulator main body 1. Fix the first pull rod 5 at the front side of the unlocking frame 207, and fix the second pull rod 501 on the top surface of the protective shell 102, which is convenient for the staff to apply force to push the top cover 101 and the protective shell 102 better when disassembling the top cover 101 and the protective shell 102, increasing the disassembly efficiency of the top cover 101 and the protective shell 102.
