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

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

[0010] In order to provide a visual window to facilitate operators to observe the situation during the test, the protective cover further includes a cover body with an open end and a hollow rod fixedly connected between the cover body and the lifting platform, wherein a transparent plate is fixedly installed on the open end of the cover body.

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

[0017] 1. This automated pre-assembly test platform for reactor production features a hollow shaft, exhaust assembly, first bellows, and circulation pipe. The fan draws exhaust gas generated during testing into the hollow shaft through the first bellows. Water flows through the horizontal pipe into the hollow shaft, creating a spray pattern. Water contacts the exhaust gas, capturing and removing solid particles in the exhaust gas. When components inside the reactor overload and burn, the temperature inside the housing rises, causing the paraffin wax to expand and push the piston plate to move. The interaction between the pull rope and the first spring allows the sleeve to move accordingly, changing its position within the tee and adjusting the flow between the through-hole and the circulation pipe. At this point, the through-hole corresponds to the circulation pipe, and some cold water enters the second bellows through the through-hole before being discharged from the mesh plate for fire extinguishing.

[0018] 2. This automated pre-assembly test platform for reactor production has a feature that, when the protective cover descends, contacts the test seat, forming an independent test area. Simultaneously, the receiving slot inside the cover contacts the insertion rod. Due to the inclined contact surface, as the protective cover continues to descend, the insertion rod is gradually pulled out of the slot, simultaneously stretching the second spring, ultimately achieving automatic alignment and locking of the reactor.

[0019] 3. The automated pre-assembly test platform for the production of the reactor has a hollow shaft formed by plugging the first shaft and the second shaft. When the lifting platform drives the exhaust assembly downward, the connection is tighter and it is convenient to disassemble and clean. A filter plate is installed in the first shaft to filter impurities discharged during flue gas cleaning to prevent pipe blockage. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only 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 terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are 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 direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0042] Example:

[0043] Reference Figures 1-8 , an automated pre-assembly test platform for reactor production, comprising a test bench 1, and a detection seat 2 uniformly arranged around the test bench 1, the reactor is placed on the detection seat 2, a lifting platform 3 is provided above the test bench 1, a protective cover 4 corresponding to the detection seat 2 is fixedly installed on the lifting platform 3, the lifting platform 3 is moved up and down by an electric or hydraulic system, preferably driven by a cylinder, which has the characteristics of fast response and is used to control the relative position between the protective cover 4 and the detection seat 2 to form a test environment, and 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 ensures a flexible connection between the two and maintains good airtightness , so that the sealing state can be maintained even during the movement of the lifting platform 3, wherein an exhaust component 7 is fixedly installed on the lifting platform 3. When the protective cover 4 abuts against the detection seat 2, the exhaust component 7 is sealed and connected to the hollow shaft 5 to discharge the harmful gases generated during the test and ensure safe operation; the circulation pipe 8 is fixedly installed on the test bench 1, one end of which 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 first corrugated pipe 6 through the hollow shaft 5, 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, thereby achieving purification.

[0044] The automated pre-installed test platform for reactor production first places the reactor to be tested on the test seat 2, starts the cylinder-driven lifting platform 3, and drives the protective cover 4 to slowly descend until it is completely in contact with the test seat 2. At this time, the space inside the protective cover 4 is sealed to form an independent test area. Once the protective cover 4 is in sealed contact with the test 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 gas that may be generated during the test is effectively extracted and discharged to ensure safe operation. At the same time, the water pump in the circulation pipe 8 also starts to work, drawing cold water from the external water source and passing through the airtight pipe 8. The hollow shaft 5 contacts the exhaust gas discharged from the first bellows 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, thereby achieving purification. After the above conditions are prepared, the inductor can be subjected to a series of functional tests and high-voltage tests according to the predetermined procedure. All test data will be collected, recorded and stored in real time for subsequent analysis and evaluation. After the test is completed, the exhaust component 7 and the circulation pipe 8 are stopped, and then the lifting platform 3 is lifted, the protective cover 4 is opened, and the tested inductor is taken out to prepare for the next round of testing.

[0045] The automated pre-assembly test platform for reactor production also includes a protective frame 15 and a water tank 9 placed in the protective frame 15. The end of the circulation pipe 8 away from the hollow shaft 5 extends into the water tank 9 to ensure that the cooling water circulation path is complete. The test bench 1 is fixedly installed on the water tank 9. A return port 901 is provided on the side of the water tank 9 close to the test bench 1. The hollow shaft 5 is threadedly connected to the return port 901 to ensure that the cooling water circulation path is complete and well sealed.

[0046] The circulation pipe 8 includes an L-shaped bent pipe 801 for connecting to the water tank 9, and a tee pipe 802 is fixedly installed at the other end of the L-shaped bent pipe 801. A horizontal pipe 804 is sealed between the tee pipe 802 and the hollow shaft 5. It also includes a second bellows 803, which is sealed between the tee pipe 802 and the protective cover 4. A shaft sleeve 11 is elastically installed in the second bellows 803 and the tee pipe 802, and a through hole 1101 is opened on the shaft sleeve 11. A one-way valve 16 is fixedly installed in the end of the shaft sleeve 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 opposite direction.

[0047] Through the arrangement of the above structure, the water pump in the circulation pipe 8 starts to work, drawing cold water from the water tank 9, passing through the L-shaped bent pipe 801 and the three-way pipe 802, and under the obstruction of the one-way valve 16, the water flows through the horizontal pipe 804 into the hollow shaft 5 to form a spray state, contact with the exhaust gas, capture and remove solid particles in the exhaust gas, and the purified water flows into the reflux port 901 in the water tank 9 through the hollow shaft 5, completing 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 platform 3, allowing cold water to pass through. A transparent plate 403 is fixedly installed on the open end of the cover body 401 to provide a visual window to facilitate the operator to observe the situation during the test.

[0049] One end of the hollow rod 402 away from the lifting platform 3 extends into the cover body 401 and is fixedly installed with a mesh plate 404 , on which a piston assembly 10 is fixedly installed. 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 in the second bellows 803, and a first spring 14 is sleeved on the pull rope 12. The two ends of the first spring 14 are fixedly connected to the retaining ring 13 and the shaft sleeve 11 respectively. In the original state, the first spring 14 is in a compressed state, so that the through hole 1101 on the shaft sleeve 11 is in close contact with the inner wall of the tee pipe 802, thereby blocking the path of cold water to the second bellows 803;

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

[0052] Through the arrangement of the above structure, during the reactor test, if a short circuit occurs suddenly, the components inside the reactor may be overloaded, heated and burned. At this time, the temperature inside the cover 401 rises, causing the paraffin to expand and push the piston plate 1002 to move. Through the interaction between the pull rope 12 and the first spring 14, the sleeve 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 bellows 803 through the through hole 1101, and is then discharged from the mesh plate 404 for fire extinguishing. When the temperature drops, the paraffin contracts, the piston plate 1002 resets, and the sleeve 11 returns to its initial state.

[0053] The detection seat 2 includes a positioning plate 201 fixedly mounted on the test bench 1, and a positioning seat 202 fixedly mounted on the positioning plate 201. A water collecting box 203 is slidably mounted in the positioning seat 202. The positioning seat 202 is provided with a water outlet 204 that passes through the internal cavity of the water collecting box 203 and is used to collect condensed water or any liquid that may leak. The water can be easily drawn out for cleaning or replacement to prevent accumulated water from affecting the test environment or damaging the equipment.

[0054] A sliding groove 205 is provided on the positioning seat 202, and a positioning block 206 is slidably installed in the sliding groove 205 through an elastic member. Preferably, the elastic member is a second spring 17, and a positioning pin 207 for positioning the inductor is fixedly installed at one end of the positioning block 206, and a plug rod 208 is fixedly installed at the other end of the positioning block 206. A receiving groove 405 adapted to the plug rod 208 is provided inside the cover body 401, wherein the contact surfaces of the plug rod 208 and the receiving groove 405 are both inclined surfaces to ensure that when the protective cover 4 descends, the plug rod 208 can smoothly enter the receiving groove 405, and realize automatic alignment and locking through the guidance of the inclined surface.

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

[0056] The hollow shaft 5 includes a first shaft body 501 threadedly installed in the return port 901, and a filter plate 502 is installed in the first shaft body 501 for filtering impurities discharged during flue gas cleaning to prevent clogging of the pipeline. A first pipe sleeve 503 is equidistantly installed on the outer edge surface of the first shaft body 501 and is connected to the interior of the first shaft body 501 for connecting to the first corrugated pipe 6 to achieve a better sealing effect, and a second shaft body 504, and a second pipe sleeve 505 is equidistantly installed on the outer edge surface of the second shaft body 504 and is connected to the interior of the second shaft body 504 for connecting to the horizontal pipe 804. The first shaft body 501 has a plug-in portion 506 connected to the second shaft body 504, and a sealing ring 507 is equidistantly installed on the plug-in portion 506 for enhancing the sealing between the first shaft body 501 and the second shaft body 504 to prevent cooling water leakage and ensure the reliability of the device. At the same time, the detachable first shaft body 501 and the second shaft body 504 are more convenient to clean.

[0057] Working principle: First, place the inductor to be tested on the test seat 2, ensuring that it is correctly positioned and firmly fixed by the positioning pin 207. At this time, the positioning block 206 remains extended under the action of the second spring 17, so that the positioning pin 207 is accurately inserted into the predetermined position of the inductor, and the cylinder-driven lifting platform 3 is started to drive the protective cover 4 to slowly descend until it is completely in contact with the test seat 2. When the protective cover 4 descends, the receiving groove 405 inside the cover body 401 contacts the insertion rod 208. Since the contact surface is a sloped design, as the protective cover 4 continues to descend, the insertion rod 208 will gradually be pulled out of the slide groove 205, and at the same time, the second spring 17 will be stretched, finally realizing the automatic alignment and locking function of the inductor, and ensuring the connection between the protective cover 4 and the test seat 2. During the inspection, the fan 702 starts to extract the air in the protective cover 4 through the hollow shaft 5 and the first bellows 6. The air is purified through the filter material in the filter box 701, and the harmful substances are removed and discharged out of the system, ensuring the safety and environmental protection of the operating environment.

[0058] At the same time, the water pump in the circulation pipe 8 also starts to work, drawing cold water from the water tank 9, passing through the L-shaped bent pipe 801 and the three-way pipe 802. Under the obstruction of the one-way valve 16, the water flows through the horizontal pipe 804 into the hollow shaft 5 to form a spray state, contact with the exhaust gas, capture and remove solid particles in the exhaust gas, and the purified water flows into the reflux port 901 in the water tank 9 through the hollow shaft 5, completing the circulation of the cooling water. When the cooling water passes through the first shaft body 501, it passes through the filter plate 502 to remove impurities, ensuring unobstructed water flow and improving cooling efficiency.

[0059] During the reactor testing process, if a short circuit occurs suddenly, the components inside the reactor may be overloaded, heated and burned. At this time, the temperature inside the cover 401 rises, causing the paraffin to expand and push the piston plate 1002 to move. Through the interaction between the pull rope 12 and the first spring 14, the sleeve 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. Part of the cold water enters the second bellows 803 through the through hole 1101, and is then discharged from the mesh plate 404 for fire extinguishing. When the temperature drops, the paraffin contracts, the piston plate 1002 resets, and the sleeve 11 returns to its initial state. After the above conditions are prepared, the reactor can be subjected to a series of functional tests and high-voltage tests according to the predetermined procedure.

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

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
