Description

Technical Field

[0001] This utility model relates to the field of iron-core reactor technology, specifically an iron-core reactor with temperature protection. Background Technology

[0002] A reactor, also called an inductor, is a device that generates a magnetic field within a certain space when current flows through it. Therefore, all current-carrying conductors have inductance in a general sense. However, the inductance of a long, straight conductor is relatively small, and the magnetic field it produces is not strong. Therefore, practical reactors are made by winding wires into a solenoid, called air-core reactors. Sometimes, to give this solenoid a larger inductance, an iron core is inserted into the solenoid, called an iron-core reactor. Reactance is divided into inductive reactance and capacitive reactance. A more scientific classification is that inductive and capacitive reactors are collectively called reactors. However, because inductors were developed first and were called reactors, the term "capacitor" now refers to a capacitive reactor, while "reactor" specifically refers to an inductor.

[0003] In the prior art, such as the announcement number CN216562662U, a high-power filtered iron-core reactor is proposed. This technical solution relates to the field of reactor technology, and in particular to a high-power filtered iron-core reactor. It includes a mounting frame, the top of which is provided with a base plate for equipment installation. A protective cover is provided on the base plate. The protective cover is provided with a heat dissipation mesh and a cooling fan. An iron-core coil with an iron core is provided on the inner side of the protective cover. The top of the protective cover is provided with an observation window to facilitate the observation of internal faults of the equipment. Through the cooling fan, the device can provide better heat dissipation performance for the high-power reactor and ensure the stable operation of the equipment.

[0004] However, existing solutions for iron-core reactors utilize heat dissipation mesh, dustproof mesh, and cooling fans to achieve good heat dissipation during operation, thus providing good protection for the iron-core reactor. However, after prolonged use, internal damage may occur. When maintenance personnel repair the reactor, the protective cover must first be disassembled. In existing solutions, the protective cover is welded or fixed to the base with screws, making disassembly inconvenient and affecting the efficiency of reactor maintenance.

[0005] To address the aforementioned issues, this application proposes a core reactor with temperature protection. Utility Model Content

[0006] The present invention aims to provide a core reactor with temperature protection, mainly to solve the problem that the protective cover on the existing core reactor is fixed to the base by welding or screws, which makes it inconvenient to disassemble the protective cover and thus affects the efficiency of reactor maintenance.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A temperature-protected iron-core reactor includes a base, a protective cover, and multiple iron-core coils on the top of the base. Insert blocks are fixedly connected to both sides of the top of the base. The bottom of the protective cover has slots that match the insert blocks. A sliding cavity is formed on the side of the insert block away from the iron-core coils. A wedge block is slidably connected inside the sliding cavity. A telescopic rod is fixedly connected to the inner wall of the sliding cavity away from the wedge block. The other end of the telescopic rod is fixedly connected to the wedge block. A spring is fitted onto the outer wall of the telescopic rod. One end of the spring is fixedly connected to the wedge block, and the other end is fixedly connected to the inner wall of the sliding cavity. A through groove matching the wedge block is formed on one side of the inner wall of the sliding cavity. A push block is slidably connected inside the through groove. One side of the push block abuts against the wedge block, and the other side extends out of the protective cover. Limiting components are provided on both sides of the protective cover above the push block.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working Principle: When damage occurs inside the iron-core reactor, pressing the push block causes the wedge block to move into the sliding cavity. When the wedge block is completely disengaged from the through slot, the protective cover can be removed and the iron-core reactor can be repaired. After the iron-core reactor is repaired, the protective cover is installed, and the insert block at the top of the base is inserted into the slot at the bottom of the protective cover. During the insertion process, the insert block will squeeze the wedge block and move it into the sliding cavity, while simultaneously squeezing the telescopic rod and spring. When the insert block is fully inserted into the slot, the wedge block will pop out under the action of the telescopic rod and spring and engage with the through slot, and the iron-core reactor can then be used normally.

[0011] 2. Beneficial effects: When the internal parts of the iron-core reactor are damaged after long-term use, the protective cover can be disassembled by pressing the push block. After the iron-core reactor is repaired, the plug at the top of the base is inserted into the slot at the bottom of the protective cover. The wedge-shaped block on the plug engages with the through slot on the protective cover, which can effectively limit the protective cover. The advantage of this design is that it makes it easier for workers to disassemble the protective cover, thereby effectively improving the efficiency of workers in repairing the iron-core reactor.

[0012] Preferably, the limiting component includes T-shaped grooves on both sides of the protective cover above the push block, a T-shaped block slidably connected inside the T-shaped groove, one side of the T-shaped block extending out of the protective cover and fixedly connected to the limiting block, and a limiting groove matching the limiting block on the top of the push block. When the operator moves the protective cover onto the base, the lower end of the limiting block is inserted into the limiting groove on the push block by moving it downwards, which can effectively limit the push block and prevent people from accidentally touching the push block and opening the protective cover during the use of the reactor, thus making the iron core reactor more stable during use.

[0013] Preferably, there are multiple telescopic rods inside the sliding cavity, which are distributed in a linear array at equal intervals inside the sliding cavity. By setting the number of telescopic rods inside the sliding cavity to multiple, and springs are sleeved on the outer walls of the telescopic rods, not only can the stability of the telescopic rods and springs moving the wedge block be improved, but also the compressive force of the telescopic rods and springs on the wedge block can be increased, thereby making the connection between the base and the protective cover more secure.

[0014] Preferably, a magnet is fixedly connected to the top of the T-shaped block, and an iron plate attracted to the magnet is fixedly connected to the top of the inner wall of the T-shaped groove. When the staff needs to disassemble the protective cover and repair the internal reactor, they need to first pull the limiting block upward to disengage it from the limiting groove on the push block. Through the magnet on the T-shaped block and the iron plate inside the T-shaped groove, when the limiting block is pulled upward to a certain extent, the magnet will attract the iron plate, thereby limiting the limiting block. At this time, the protective cover can be disassembled by pressing the push block. The advantage of this design is that people do not need to keep pulling the limiting block upward to disassemble the protective cover, making the disassembly of the protective cover more convenient.

[0015] Preferably, sliders are fixedly connected to both sides of the push block, and a groove matching the slider is opened on the inner wall of the through groove. During the sliding process of the push block inside the through groove, the sliders on both sides of the push block and the groove opened on the inner wall of the through groove can play a better role in limiting and guiding the push block. This makes the push block more stable when sliding inside the through groove and can effectively prevent the push block from leaving the through groove.

[0016] Preferably, a handle is fixedly connected to the side of the limiting block away from the T-shaped block, and the corners of the handle are all rounded. By pulling the handle on the limiting block, the limiting block can be moved up and down more easily, thus making the disassembly and assembly of the protective cover more convenient.

[0017] Preferably, the corners of the push block extending beyond the protective cover are rounded. Pressing the push block can disassemble the protective cover. By rounding the corners of the push block extending beyond the protective cover, it is more comfortable for people to press the push block and their skin will not be scratched by the corners of the push block.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-7A temperature-protected iron-core reactor includes a base 1, a protective cover 2, and multiple iron-core coils 3 on the top of the base 1. Inserts 4 are fixedly connected to both sides of the top of the base 1. The bottom of the protective cover 2 has slots 20 that match the inserts 4. When installing the protective cover 2, the inserts 4 on the base 1 are inserted into the slots 20 at the bottom of the protective cover 2. A sliding cavity 5 is formed on the side of the insert 4 away from the iron-core coils 3. A wedge-shaped block 6 is slidably connected inside the sliding cavity 5. A telescopic rod 7 is fixedly connected to the inner wall of the sliding cavity 5 on the side away from the wedge-shaped block 6. Multiple telescopic rods 7 are arranged in a linear array and evenly spaced inside the sliding cavity 5. The other end of the telescopic rod 7 is fixedly connected to the wedge-shaped block 6. A spring 8 is sleeved on the outer wall of the telescopic rod 7. One end of the spring 8 is fixedly connected to the wedge-shaped block 6, and the other end is fixedly connected to the inner wall of the sliding cavity 5. During the insertion of the insert 4 into the slot 20, it compresses the wedge-shaped block 6, causing it to move towards the sliding cavity 5. The internal movement simultaneously compresses the telescopic rod 7 and the spring 8. A through groove 9 matching the wedge block 6 is provided on one side of the inner wall of the sliding cavity 5. When the insert block 4 is fully inserted into the slot 20, the wedge block 6 will pop out under the action of the telescopic rod 7 and the spring 8 and engage with the through groove 9, and the iron core reactor can be used normally. A push block 10 is slidably connected inside the through groove 9. A slider 15 is fixedly connected to both sides of the push block 10. A sliding groove 16 matching the slider 15 is provided on the inner wall of the through groove 9. One side of the push block 10 abuts against the wedge block 6, and the other side extends out of the protective cover 2. The corners of the push block 10 extending out of the protective cover 2 are all rounded. By pressing the push block 10, the wedge block 6 is pushed into the sliding cavity 5. When the wedge block 6 is completely disengaged from the through groove 9, the protective cover 2 can be removed and the iron core reactor can be repaired. Limiting components are provided on both sides of the protective cover 2 above the push block 10.

[0028] like Figure 2 and Figure 6 As shown, the limiting component includes a protective cover 2 with T-shaped grooves 11 on both sides above the push block 10. A T-shaped block 12 is slidably connected inside the T-shaped groove 11. A magnet 17 is fixedly connected to the top of the T-shaped block 12. An iron sheet 18 attracted to the magnet 17 is fixedly connected to the top of the inner wall of the T-shaped groove 11. One side of the T-shaped block 12 extends out of the protective cover 2 and is fixedly connected to a limiting block 13. A handle 19 is fixedly connected to the side of the limiting block 13 away from the T-shaped block 12, and the corners of the handle 19 are all rounded. The top of the push block 10 has a limiting groove 14 that matches the limiting block 13. When the operator installs the protective cover 2 onto the base 1 and moves it, the lower end of the limiting block 13 is moved downwards and inserted into the limiting groove 14 on the push block 10, which can effectively limit the push block 10 and prevent people from accidentally touching the push block 10 and opening the protective cover 2 during the use of the reactor, thus making the iron core reactor more stable during use.

[0029] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0030] When the core reactor is damaged internally after prolonged use, first pull the handle 19 upwards to move the limiting block 13 upwards, disengaging it from the limiting groove 14 on the push block 10. When the limiting block 13 is pulled upwards to a certain extent, the magnet 17 will attract the iron plate 18, thus limiting the position of the limiting block 13. At this point, press the push block 10 to push the wedge block 6 into the sliding cavity 5. When the wedge block 6 is completely disengaged from the through groove 9, the protective cover 2 can be removed, and the core reactor can be repaired. After repair, install the protective cover 2. Insert the plug 4 at the top of the base 1 into the slot 20 at the bottom of the protective cover 2. During the insertion of the plug 4 into the slot 20, it will squeeze the wedge block 6 and move it into the sliding cavity 5. At the same time, it will squeeze the telescopic rod 7 and the spring 8. When the plug 4 is fully inserted into the slot 20, the wedge block 6 will pop out under the action of the telescopic rod 7 and the spring 8 and engage with the through groove 9. Then pull the handle 19 down to move the limit block 13 down. When the limit block 13 is in the limit groove 14 on the push block 10, the iron core reactor can be used normally.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
