[0001] The present invention relates to the technical field of reactor production, and particularly to an automated pre-installation and testing platform for reactor production. Background Art

[0002] As an important power equipment, reactors are widely used in power systems for regulating current, stabilizing voltage, filtering, etc. To ensure the quality and reliability of reactors, strict assembly and testing are required during the production process. Traditional reactor testing usually relies on manual operation, which is not only inefficient but also difficult to ensure the consistency and accuracy of testing.

[0003] With the improvement of industrial automation level, more and more enterprises begin to adopt automated testing platforms to replace traditional manual testing methods. Although the existing automated testing platforms have improved the testing efficiency to a certain extent, in actual applications, if the harmful gases generated during the testing process are not properly treated, they may pollute the working environment and even endanger the health of operators. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that if the harmful gases generated during the testing process in the prior art are not properly treated, they may pollute the working environment and even endanger the health of operators, and to propose an automated pre-installation and testing platform for reactor production.

When the protective cover abuts against the detection seats, the exhaust component is hermetically connected to the hollow shaft; a circulation pipe is fixedly installed on the testing table, one end is equipped with a water pump for connecting to an external water source, and the other end is connected to the hollow shaft.

[0007] To form a complete circulating water path, preferably, it also includes a protective frame and a water tank placed in the protective frame. The end of the circulation pipe away from the hollow shaft extends into the water tank. Among them, the testing table is fixedly installed on the water tank, and a return port is opened on the side of the water tank close to the testing table. The hollow shaft is threadedly connected to the return port.

[0008] In order to effectively capture and remove solid particulate matter in the exhaust gas, further, the circulation pipe includes an L-shaped bent pipe for connecting with the water tank, the other end of the L-shaped bent pipe is fixedly installed with a three-way pipe, and a horizontal pipe is hermetically connected between the three-way pipe and the hollow shaft.

[0009] In order to control the opening and closing of the second bellows, furthermore, a second bellows is further included, which is hermetically connected between the three-way pipe and the protective cover. An axle sleeve is elastically installed in the second bellows and the three-way pipe. A through hole is opened on the axle sleeve, and a one-way valve is fixedly installed at one end of the axle sleeve close to the horizontal pipe.

[0010] In order to provide a visual window for the operator to observe the situation during the test process, further, the protective cover includes a cover body with an open end and a hollow rod fixedly connected between the cover body and the lifting table. Wherein, a transparent plate is fixedly installed at the open end of the cover body.

[0011] In order to control the movement of the axle sleeve, furthermore, one end of the hollow rod away from the lifting table extends into the cover body and is fixedly installed with a net plate. A piston assembly is fixedly installed on the net plate, and a pull rope is fixedly connected between the axle sleeve and the movable end of the piston assembly.

[0012] In order to effectively handle the possible condensate or leakage liquid during the test process, further, the detection seat includes a positioning plate fixedly installed on the test bench and a positioning seat fixedly installed on the positioning plate. A water receiving box is slidably installed in the positioning seat, and a water outlet hole communicating with the internal cavity of the water receiving box is opened on the positioning seat.

[0013] In order to improve the stability and safety of the reactor during the test process, furthermore, a chute is opened on the positioning seat, a positioning block is slidably installed in the chute through an elastic member, a positioning pin for positioning the reactor is fixedly installed at one end of the positioning block, and a plug rod is fixedly installed at the other end of the positioning block. A receiving groove adapted to the plug rod is opened inside the cover body. Wherein, the contact surfaces of the plug rod and the receiving groove are both inclined surfaces.

[0014] In order to be able to effectively handle and discharge harmful gases, preferably, the exhaust air assembly includes a filter box and a fan fixedly installed on the lifting table, and filter media is filled in the filter box.

[0015] To ensure the efficient operation and good sealing of the cooling water circulation system, further, the hollow shaft includes a first shaft body threadedly installed in the return port, a filter plate is installed inside the first shaft body, first sleeves penetrating through the interior of the first shaft body are equidistantly installed on the outer edge surface of the first shaft body, and a second shaft body. Second sleeves penetrating through the interior of the second shaft body are equidistantly installed on the outer edge surface of the second shaft body. Among them, the first shaft body has a plug-in portion connected to the second shaft body, and sealing rings are equidistantly installed on the plug-in portion.

[0016] Compared with the prior art, the present invention provides an automated pre-installation test platform for the production of reactors, which has the following beneficial effects:

[0017] 1. For this automated pre-installation test platform for the production of reactors, through the settings of the hollow shaft, the exhaust component, the first corrugated pipe, and the circulation pipe, the fan inhales the exhaust gas generated during detection into the hollow shaft through the first corrugated pipe. The water flow enters the hollow shaft through the horizontal pipe to form a spraying state, contacts the exhaust gas, captures and removes the solid particles in the exhaust gas. When the components inside the reactor are overloaded and catch fire, the temperature inside the cover rises accordingly, causing the paraffin to expand and push the piston plate to move. Through the interaction of the pull rope and the first spring, the shaft sleeve can move correspondingly, changing its position in the three-way pipe and adjusting the flow state between the through hole and the circulation pipe. At this time, the through hole corresponds to the circulation pipe, and part of the cold water enters the second corrugated pipe through the through hole and then discharges from the mesh plate for fire extinguishing;

[0018] 2. For this automated pre-installation test platform for the production of reactors, when the protective cover descends, it abuts against the detection seat, forming an independent test area. At the same time, the receiving groove inside the cover contacts the insertion rod. Due to the inclined surface design of the contact surface, as the protective cover continues to descend, the insertion rod will gradually be pulled out of the sliding groove, stretching the second spring at the same time, and finally realizing the automatic alignment and locking function of the reactor;

[0019] 3. For this automated pre-installation test platform for the production of reactors, the hollow shaft formed by the insertion of the first shaft body and the second shaft body is more tightly connected when the lifting platform drives the exhaust component to press down, and it is also convenient for disassembly and cleaning. A filter plate is installed inside the first shaft body to filter the impurities discharged when cleaning the flue gas and prevent blockage of the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0041] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0042] Embodiment:

[0043] Referring to Figures 1-8 , an automatic pre-installation test platform for the production of reactors, includes a test bench 1, and detection seats 2 evenly arranged around the test bench 1. The reactor is placed on the detection seats 2. Above the test bench 1, there is a lifting platform 3. A protective cover 4 corresponding to the detection seats 2 is fixedly installed on the lifting platform 3. The lifting platform 3 moves up and down through an electric or hydraulic system, preferably driven by a cylinder, which has the characteristic of fast response and is used to control the relative position between the protective cover 4 and the detection seats 2 to form a test environment. It also includes: a hollow shaft 5 coaxially arranged with the test bench 1. A first bellows 6 is connected between the protective cover 4 and the hollow shaft 5. The first bellows 6 not only ensures the flexible connection between the two, but also maintains good airtightness, so that even during the movement of the lifting platform 3, the sealed state can be maintained. Among them, an exhaust component 7 is fixedly installed on the lifting platform 3. When the protective cover 4 abuts against the detection seats 2, the exhaust component 7 is hermetically connected to the hollow shaft 5 and is used to discharge the harmful gases generated during the test to ensure operation safety; a circulation pipe 8 is fixedly installed on the test bench 1. One end is equipped with a water pump for connecting to an external water source, and the other end is connected to the hollow shaft 5. The water flow inside the circulation pipe 8 contacts the exhaust gas discharged from the hollow shaft 5 and the first bellows 6, effectively capturing and removing the solid particles in the exhaust gas, such as dust, smoke and other suspended particles. After the water droplets collide with the particles, they become heavier and settle down, thereby achieving purification.

[0044] For the automated pre-installation test platform used in the production of this reactor, first place the reactor to be tested on the detection seat 2, start the lifting platform 3 driven by the cylinder, and make it drive the protective cover 4 to slowly descend until it is in full contact with the detection seat 2. At this time, the space inside the protective cover 4 is sealed, forming an independent test area. Once the protective cover 4 is in sealed contact with the detection seat 2, the exhaust component 7 is immediately started. Through the sealed connection between the hollow shaft 5 and the protective cover 4, any harmful gases that may be generated during the test are effectively extracted and discharged to ensure operation safety. At the same time, the water pump in the circulation pipe 8 also starts to work, extracting cold water from an external water source. The cold water contacts the exhaust gas discharged from the hollow shaft 5 and the first corrugated pipe 6, effectively capturing and removing solid particles in the exhaust gas, such as dust, smoke, and other suspended particles. After the water droplets collide with the particles, they become heavier and settle down, thus achieving purification. After the above conditions are prepared, a series of functional tests and high-voltage tests can be carried out on the reactor according to a predetermined program. All test data will be collected, recorded, and stored in real time for subsequent analysis and evaluation. After the test is completed, stop the operation of the exhaust component 7 and the circulation pipe 8, then lift the lifting platform 3, open the protective cover 4, take out the tested reactor, and prepare for the next round of testing.

[0045] The automated pre-installation test platform used in the production of this reactor further includes a protective frame 15 and a water tank 9 placed inside the protective frame 15. One end of the circulation pipe 8 far from the hollow shaft 5 extends into the water tank 9 to ensure the integrity of the cooling water circulation path. Among them, the test bench 1 is fixedly installed on the water tank 9. A return port 901 is opened on one side of the water tank 9 close to the test bench 1, and the hollow shaft 5 is threadedly connected to the return port 901 to ensure the integrity and good sealing of the cooling water circulation path.

[0046] The circulation pipe 8 includes an L-shaped bent pipe 801 for connecting to the water tank 9. The other end of the L-shaped bent pipe 801 is fixedly installed with a tee pipe 802. A horizontal pipe 804 is hermetically connected between the tee pipe 802 and the hollow shaft 5. It also includes a second corrugated pipe 803, which is hermetically connected between the tee pipe 802 and the protective cover 4. A bushing 11 is elastically installed inside the second corrugated pipe 803 and the tee pipe 802. A through hole 1101 is opened on the bushing 11. A one-way valve 16 is fixedly installed at one end of the bushing 11 close to the horizontal pipe 804 to ensure that the cooling water can only flow from the water tank 9 to the hollow shaft 5 and will not flow in the reverse direction.

[0047] Through the setting of the above structure, the water pump in the circulation pipe 8 starts to work, extracting cold water from the water tank 9, passing through the L-shaped bent pipe 801 and the tee pipe 802. Blocked by the one-way valve 16, the water flow enters the hollow shaft 5 through the horizontal pipe 804 to form a spray state, contacts the exhaust gas, captures and removes solid particles in the exhaust gas, and the purified water flows into the return port 901 in the water tank 9 through the hollow shaft 5 to complete the circulation of the cooling water.

[0048] The protective cover 4 includes a cover body 401 with an open end and a hollow rod 402 fixedly connected between the cover body 401 and the lifting table 3, allowing cold water to pass through. Wherein, a transparent plate 403 is fixedly installed at the open end of the cover body 401, providing a visualization window for the operator to observe the situation during the test process.

[0049] One end of the hollow rod 402 far from the lifting table 3 extends into the cover body 401 and is fixedly installed with a mesh plate 404. A piston assembly 10 is fixedly installed on the mesh plate 404. A pull rope 12 is fixedly connected between the sleeve 11 and the movable end of the piston assembly 10.

[0050] It should be noted that a retaining ring 13 is fixedly installed inside the second corrugated pipe 803. A first spring 14 is sleeved on the pull rope 12. The two ends of the first spring 14 are respectively fixedly connected with the retaining ring 13 and the sleeve 11. In the original state, the first spring 14 is in a compressed state, making the through hole 1101 on the sleeve 11 close to the inner wall of the three-way pipe 802, closing the path of cold water leading to the second corrugated pipe 803;

[0051] The piston assembly 10 includes a base 1001 fixedly installed on the mesh plate 404, forming the outer shell of the piston assembly 10. A piston plate 1002 is movably installed inside the base 1001. A connecting end 1003 is fixedly installed on the piston plate 1002 for connecting the pull rope 12. Paraffin is filled in the cavity formed between the base 1001 and the piston plate 1002. The paraffin can expand or contract according to the temperature change, thereby pushing the piston plate 1002 to move.

[0052] Through the setting of the above structure, during the reactor test, if a short circuit suddenly occurs, the components inside the reactor may be overloaded, heated and burned. At this time, the temperature inside the cover body 401 rises accordingly, causing the paraffin to expand and push the piston plate 1002 to move. Through the interaction of the pull rope 12 and the first spring 14, the sleeve 11 can move accordingly, changing its position in the three-way pipe 802, adjusting the flow state between the through hole 1101 and the circulation pipe 8. At this time, the through hole 1101 corresponds to the circulation pipe 8, and part of the cold water enters the second corrugated pipe 803 through the through hole 1101 and then is discharged from the mesh plate 404 for fire extinguishing. When the temperature drops, the paraffin shrinks, the piston plate 1002 resets, and the sleeve 11 returns to the initial state.

[0053] The detection seat 2 includes a positioning plate 201 fixedly installed on the test bench 1 and a positioning seat 202 fixedly installed on the positioning plate 201. A water receiving box 203 is slidably installed inside the positioning seat 202. A water outlet hole 204 communicating with the internal cavity of the water receiving box 203 is opened on the positioning seat 202, for collecting condensed water or any liquid that may leak, and can be conveniently pulled out for cleaning or replacement, preventing water accumulation from affecting the test environment or damaging the equipment.

[0054] The positioning base 202 is provided with a sliding groove 205. A positioning block 206 is slidably installed in the sliding groove 205 through an elastic member. Preferably, the elastic member is the second spring 17. One end of the positioning block 206 is fixedly installed with a positioning pin 207 for positioning the reactor, and the other end of the positioning block 206 is fixedly installed with a plug rod 208. An accommodating groove 405 adapted to the plug rod 208 is provided inside the cover body 401. Among them, the contact surfaces of the plug rod 208 and the accommodating groove 405 are both inclined surfaces, so as to ensure that when the protective cover 4 descends, the plug rod 208 can smoothly enter the accommodating groove 405 and realize automatic alignment and locking through the guidance of the inclined surfaces.

[0055] The exhaust air assembly 7 includes a filter box 701 and a blower 702 fixedly installed on the lifting platform 3. The filter box 701 is filled with filter materials such as activated carbon and HEPA filters, which can effectively remove particulate matter, harmful gases and odors in the exhaust gas, ensuring that the discharged air is clean and safe. The blower 702 is connected to the filter box 701 and is responsible for extracting the air in the hollow shaft 5 and discharging it through the filter box 701. The blower 702 can be selected with different air volumes and powers according to actual needs to adapt to different test environments.

[0056] The hollow shaft 5 includes a first shaft body 501 threadedly installed in the return port 901. A filter plate 502 is installed inside the first shaft body 501 for filtering impurities discharged when cleaning the flue gas to prevent blockage of the pipeline. First pipe sleeves 503 that are internally connected to the first shaft body 501 are equidistantly installed on the outer edge surface of the first shaft body 501 for connecting the first corrugated pipe 6 to achieve a better sealing effect, and a second shaft body 504. Second pipe sleeves 505 that are internally connected to the second shaft body 504 are equidistantly installed on the outer edge surface of the second shaft body 504 for connecting the horizontal pipe 804. Among them, the first shaft body 501 has a plug-in portion 506 connected to the second shaft body 504. Sealing rings 507 are equidistantly installed on the plug-in portion 506 for enhancing the sealing performance between the first shaft body 501 and the second shaft body 504 to prevent leakage of cooling water and ensure the reliability of the device. At the same time, the detachable connection between the first shaft body 501 and the second shaft body 504 is more convenient for cleaning.

[0057] Working principle: First, place the reactor under test on the detection seat 2 to ensure its correct positioning and firm fixation by the positioning pin 207. At this time, the positioning block 206 remains extended under the action of the second spring 17, enabling the positioning pin 207 to accurately insert into the predetermined position of the reactor. Start the lifting platform 3 driven by the cylinder, and make it drive the protective cover 4 to slowly descend until it is in full contact with the detection seat 2. When the protective cover 4 descends, the receiving groove 405 inside the cover body 401 contacts the insertion rod 208. Due to the inclined surface design of the contact surface, as the protective cover 4 continues to descend, the insertion rod 208 will gradually be pulled out of the sliding groove 205, while stretching the second spring 17, ultimately realizing the automatic alignment and locking functions of the reactor, as well as ensuring the connection between the protective cover 4 and the detection seat 2. During detection, the fan 702 starts to extract the air inside the protective cover 4 through the hollow shaft 5 and the first corrugated pipe 6. The air is purified through the filter material in the filter box 701, and the harmful substances are removed and then discharged out of the system to ensure the safety and environmental protection of the operating environment.

[0058] Meanwhile, the water pump in the circulation pipe 8 also starts to work, extracting cold water from the water tank 9. After passing through the L-shaped bent pipe 801 and the three-way pipe 802, blocked by the one-way valve 16, the water flow enters the hollow shaft 5 through the horizontal pipe 804 to form a spraying state, contacts the waste gas, captures and removes the solid particles in the waste gas. The purified water flows into the return port 901 in the water tank 9 through the hollow shaft 5 to complete the circulation of the cooling water. When the cooling water passes through the first shaft body 501, impurities are removed through the filter plate 502 to ensure unobstructed water flow and improve the cooling efficiency.

[0059] During the reactor test, if a short circuit suddenly occurs, the components inside the reactor may overheat and burn. At this time, the temperature inside the cover body 401 rises, causing the paraffin to expand and push the piston plate 1002 to move. Through the interaction of the pull rope 12 and the first spring 14, the bushing 11 can move accordingly, changing its position in the three-way pipe 802 and adjusting the flow state between the through hole 1101 and the circulation pipe 8. At this time, the through hole 1101 corresponds to the circulation pipe 8, and part of the cold water enters the second corrugated pipe 803 through the through hole 1101 and then is discharged from the mesh plate 404 for fire extinguishing. When the temperature drops, the paraffin shrinks, the piston plate 1002 resets, and the bushing 11 returns to its initial state. After the above conditions are prepared, a series of functional tests and high-voltage tests can be carried out on the reactor according to the predetermined program.

[0060] All test data will be collected, recorded, and stored in real time for subsequent analysis and evaluation.

[0061] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
