[0002] A fire damper is a fire protection component that is generally installed on the pipes of a mechanical smoke exhaust system. It is normally open and opens to exhaust smoke when a fire occurs. It closes when the smoke temperature in the exhaust pipe reaches the set temperature and meets the smoke leakage and fire resistance integrity requirements within a certain period of time, thereby isolating smoke and preventing fire.

[0003] However, in the prior art, after the production of existing fire dampers, it is necessary to conduct an air leakage test to ensure the use effect of the final product. However, during the air leakage detection process, the existing fire dampers cannot intuitively observe the actual air leakage conditions after installation, and need to be tested with existing testing equipment. The actual detection efficiency is low, and different specifications of existing fire dampers require different testing equipment, which leads to the poor actual use of existing testing equipment.

[0015] A method for detecting a highly corrosion-resistant fire damper comprises the following steps:

[0016] S1. Adaptive installation: according to the actual specifications of the fire damper to be tested, the first installation frame and the second installation frame are replaced and selected, and then the fire damper to be tested is matched. Then, by rotating the connecting worm, the rotating connecting worm can cooperate with the connecting worm gear to drive the connecting shaft to rotate, and then the rotating connecting shaft cooperates with the connecting bevel gear to drive the movable threaded rod to rotate, so that the rotating movable threaded rod can adjust the position of the push piece connected with it in the horizontal direction, so that the push piece can squeeze and push the moving block during the position change. Since the sliding rod slides through the moving block, the moving block can move along the sliding rod direction between the push piece and the corresponding mounting strip, thereby facilitating the adjustment of the distance between the moving block and the fixed block, and facilitating the stable connection between the fire damper to be tested and the replaced first installation frame or the second installation frame. Then, the connecting worm is rotated in the opposite direction to move the push piece away from the moving block, so that the moving block will not be squeezed by the push piece to affect the connection effect between the fire damper to be tested and the first installation frame or the second installation frame, thereby simulating the actual installation effect.

[0017] S2. Simulation detection: the existing exhaust gas purification equipment is set inside the air collecting frame. When the air leakage of the fire damper to be detected is detected, the ignited combustible material is placed on the top of the combustion rack. At this time, the fan is operated at a low speed so that the flowing airflow generated by the fan operation is injected into the air guide frame under the obstruction of the first partition, and then a small amount of air is injected into the insulation frame, so that the combustible material cannot be fully burned, thereby generating more smoke. At the same time, the smoke and heat will be driven by the flowing airflow to be injected into the corresponding side pipe and extension pipe through the insulation frame and the conveying frame, and then flow through the fire damper to be detected through the corresponding extension frame and the first installation frame or the second installation frame. When the flowing air temperature reaches the set temperature of the fire damper to be detected, the connection between the two extension frames is cut off, so that the smoke can only gather on one side of the fire damper to be detected, and then observe whether there is a large The smoke is released, and the air leakage condition of the fire damper to be tested can be observed visually. After the fire damper to be tested is reset, the running speed of the fan is increased, and at the same time, an appropriate amount of common acidic and alkaline solution or waste solution is injected into the space on one side of the second partition through the injection pipe, so that a large amount of flowing air generated by the fan can be injected into the insulation frame, so that the combustible material can be fully burned, thereby simulating the actual fire condition. At this time, the combustion frame transfers the high temperature to the solution through the heat conduction plate and the heat conduction sheet, thereby accelerating the evaporation of the solution, and then the evaporated solution follows the flowing air flow to flow through the fire damper to be tested, and at the same time, the speed at which the flowing air flow temperature rises to the safe temperature can be reduced, so that the evaporated solution can fully contaminate the fire damper to be tested, until the flowing air flow temperature reaches the set safe temperature of the fire damper to be tested, and then it can be tested whether the fire damper to be tested can normally perform its due functions under different operating environments;

[0018] S3. Safety protection: The flowing gas passing through the fire damper to be tested can be injected into the collection frame through the extension frame, extension pipe and side frame on the other side, and finally injected into the existing exhaust gas purification equipment inside the gas collection frame.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0020] (1) In the present invention, when in use, the first installation frame and the second installation frame are replaced and selected according to the actual specifications of the fire damper to be tested, and then the fire damper to be tested is matched. Then, by rotating the connecting worm, the rotating connecting worm can cooperate with the connecting worm wheel to drive the connecting shaft to rotate, and then the rotating connecting shaft can cooperate with the connecting bevel gear to drive the moving threaded rod to rotate, so that the rotating moving threaded rod can adjust the position of the push piece connected to it with the thread in the horizontal direction, so that the push piece can squeeze and push the moving block during the position change process, and since the slide rod slides through the moving block, the moving block can move along The sliding rod moves between the push piece and the corresponding mounting strip, thereby facilitating adjustment of the distance between the moving block and the fixed block, and facilitating a firm connection between the fire damper to be tested and the replaced first mounting frame or the second mounting frame. The linked worm is then rotated in the opposite direction to move the push piece away from the moving block, so that the moving block will not be squeezed by the push piece and affect the connection effect between the fire damper to be tested and the first mounting frame or the second mounting frame, thereby effectively simulating the actual installation effect, and facilitating the installation setting of fire dampers to be tested of different specifications simulating actual installation conditions, thereby effectively improving the practical use versatility of the equipment.

[0021] (2) In the present invention, when in use, the existing exhaust gas purification equipment is set inside the air collecting frame. When the air leakage condition of the fire damper to be detected is detected, the ignited combustible material is placed on the top of the combustion rack. At this time, the fan is operated at a low speed, so that the flowing airflow generated by the fan operation is injected into the air guide frame under the obstruction of the first partition, and then a small amount of air is injected into the insulation frame, so that the combustible material cannot be fully burned, thereby generating more smoke. At the same time, the smoke and heat will be driven by the flowing airflow to be injected into the corresponding side pipe and extension pipe through the insulation frame and the conveying frame, and then flow through the fire damper to be detected through the corresponding extension frame and the first installation frame or the second installation frame. When the flowing air temperature reaches the set temperature of the fire damper to be detected, the connection between the two extension frames is cut off, so that the smoke can only gather on one side of the fire damper to be detected, and then by observing whether there is a large amount of smoke emitted at the connection between the fire damper to be detected and the first installation frame or the second installation frame, it can be directly detected. Observe the air leakage of the fire damper to be tested, and then reset the fire damper to be tested, increase the running speed of the fan, and at the same time inject an appropriate amount of common acid and alkaline solution or waste solution into the space on one side of the second partition through the injection pipe, so that the large amount of flowing air generated by the fan can be injected into the insulation frame, so that the combustible material can be fully burned, thereby simulating the actual fire condition. At this time, the combustion frame transfers the high temperature to the solution through the heat conduction plate and the heat conduction sheet, thereby accelerating the evaporation of the solution, and then the evaporated solution follows the flowing air flow through the fire damper to be tested, and at the same time can effectively reduce the speed at which the flowing air flow temperature rises to a safe temperature, so that the evaporated solution can fully contaminate the fire damper to be tested, until the flowing air flow temperature reaches the set safe temperature of the fire damper to be tested, and then it can effectively detect whether the fire damper to be tested can normally perform its functions under different operating environments, effectively improve the actual detection efficiency of the equipment, and reduce the actual detection cost.

[0022] (3) In the present invention, when in use, the flowing gas flowing through the fire damper to be tested can be injected into the collection frame through the extension frame, extension pipe and side frame on the other side, and finally injected into the existing waste gas purification equipment inside the gas collection frame, thereby effectively preventing the generated waste gas emissions from affecting the surrounding environment, improving the actual use effect of the equipment, and enabling the equipment to efficiently perform its functions.

[0034] Example 1, please refer to Figure 1 、 Figure 2 and Figure 3 A highly corrosion-resistant fire damper detection system includes a connecting mechanism 1 and an adjusting mechanism 2.

[0035] The details are as follows:

[0036] See also Figure 4 、 Figure 5 and Figure 6The connecting mechanism 1 includes a connecting frame 108, a connecting component and a limiting component. There are two connecting frames 108. A connecting plate 111 is slidably inserted inside each connecting frame 108. The outer surfaces of one side of the two connecting plates 111 are fixedly connected to a first mounting frame 112 and a second mounting frame 113. The connecting component is used to connect the two connecting frames 108 to form a sealed conveying channel. The limiting component is used to adjust the relative position of the two connecting frames 108 in the horizontal direction. A plurality of positioning bolts 114 are threadedly connected to the outer surface of one side of each connecting frame 108. The walls are fixedly connected with sealing gaskets 109. Since the connecting plate 111 is slidably inserted into the interior of the connecting frame 108, it is convenient to replace, install and disassemble the first installation frame 112 and the second installation frame 113, and thus facilitate the installation and setting of fire dampers to be tested of different specifications. The rotating positioning bolts 114 can limit the extrusion of the position of the connecting plate 111 in the connecting frame 108, making it convenient and stable to install and replace the connecting plate 111. The sealing gasket 109 is attached to one side of the connecting plate 111, thereby ensuring the sealing of the connection of the fire damper not to be tested during testing, thereby improving the actual detection accuracy.

[0037] The limiting component includes a base 101, a movable threaded rod 119, a push piece 120, a movable block 117 and a fixed block 118. The movable block 117 is slidably embedded in the top of the base 101, and the top of the movable block 117 is fixedly connected to the bottom of the corresponding connecting frame 108. The fixed block 118 is fixedly connected to the top of the base 101, and the top of the fixed block 118 is fixedly connected to the bottom of the corresponding connecting frame 108. A movable opening is opened at the top of the base 101, and the push piece 120 is slidably inserted inside the movable opening.

When the linkage worm 110 is rotated, the rotating linkage worm 110 cooperates with the linkage worm gear to drive the linkage shaft 121 to rotate. The rotating linkage shaft 121 effectively drives the moving threaded rod 119 to rotate through the linkage bevel gear.

One of the extension frames 10 A sealing ring 106 is fixedly connected to the outer surface of one side, and a sealing tube 107 is inserted into the sealing ring 106. One end of the sealing tube 107 is sleeved on the outer surface of the corresponding side tube 103, and the sealing tube 107 is slidably sleeved on the outer surface of the corresponding extension tube 104. Through the two sets of side frames 102, side tubes 103, extension tubes 104 and extension frames 105, flowing air can be sealed and transported. The expansion and contraction of the sealing tube 107 improves the sealing effect between the corresponding extension frame 105 and the extension tube 104 during movement.

The conveying frame 212 is connected and arranged on the outer surface of one side of the temperature-isolating frame 206. The collecting frame 202 is connected and arranged on the outer surface of one side of the gas collecting frame 201. The regulating component is used to simulate the detection environment. The exhaust gas can be collected by the collecting frame 202 and the gas collecting frame 201.

[0042] The following is a detailed description of a highly corrosion-resistant fire damper detection method provided by an embodiment of the present invention. The method of use includes the following steps:

[0043] Step 1, adaptive installation: According to the actual specifications of the fire damper to be tested, the first installation frame 112 and the second installation frame 113 are replaced and selected to match the fire damper to be tested, and then the rotating linkage worm 110 is rotated to make the rotating linkage worm 110 cooperate with the linkage worm gear to drive the linkage shaft 121 to rotate, and then the rotating linkage shaft 121 cooperates with the linkage bevel gear to drive the movable threaded rod 119 to rotate, so that the rotating movable threaded rod 119 can adjust the position of the push piece 120 threadedly connected thereto in the horizontal direction, so that the push piece 120 can squeeze and push the movable block 117 during the position change process, and since the slide rod 116 slides through the movable block 117, the movable block 117 can move along the slide rod The push piece 120 is moved in the direction 116 between the push piece 120 and the corresponding mounting bar 115, thereby facilitating adjustment of the distance between the movable block 117 and the fixed block 118, facilitating a stable connection between the fire damper to be tested and the replaced first mounting frame 112 or second mounting frame 113. The linked worm 110 is then rotated in the opposite direction to move the push piece 120 away from the movable block 117, so that the movable block 117 will not be squeezed by the push piece 120 and affect the connection effect between the fire damper to be tested and the first mounting frame 112 or second mounting frame 113. This effectively simulates the actual installation effect, facilitates the installation and setting of fire dampers to be tested of different specifications simulating actual installation conditions, and effectively improves the practical use versatility of the equipment.

[0044] Step 2, simulation test: the existing exhaust gas purification equipment is set inside the gas collecting frame 201. When the fire damper to be tested is tested for air leakage, the ignited combustible material is placed on the top of the combustion rack 218. At this time, the fan 204 is operated at a low speed, so that the flow air generated by the fan 204 is injected into the air guide frame 205 under the obstruction of the first partition 203, and then a small amount of air is injected into the insulation frame 206, so that the combustible material cannot be fully burned, thereby generating more smoke. At the same time, the smoke and heat will be carried by the flow air. The smoke is injected into the corresponding side pipe 103 and the extension pipe 104 through the insulation frame 206 and the conveying frame 212, and then flows through the fire damper to be detected through the corresponding extension frame 105 and the first installation frame 112 or the second installation frame 113. When the flowing air temperature reaches the set temperature of the fire damper to be detected, the connection between the two extension frames 105 is cut off, so that the smoke can only gather on one side of the fire damper to be detected. Then, by observing whether there is a relatively high temperature at the connection between the fire damper to be detected and the first installation frame 112 or the second installation frame 113, the smoke is discharged. The large amount of smoke is released, and the air leakage condition of the fire damper to be tested can be observed visually. After the fire damper to be tested is reset, the running speed of the fan 204 is increased, and at the same time, an appropriate amount of common acidic and alkaline solution or waste solution is injected into the space on one side of the second partition 207 through the injection pipe 210, so that the large amount of flowing air generated by the fan 204 can be injected into the insulation frame 206, so that the combustible material can be fully burned, thereby simulating an actual fire condition. At this time, the combustion frame 213 transfers the high temperature to the solution through the heat conducting plate 208 and the heat conducting sheet 209, thereby accelerating the evaporation of the solution, and then allowing the evaporated solution to flow through the fire damper to be tested with the flowing air flow, and at the same time, it can effectively reduce the speed at which the flowing air flow temperature rises to a safe temperature, so that the evaporated solution can fully contaminate the fire damper to be tested, until the flowing air flow temperature reaches the set safe temperature of the fire damper to be tested, thereby effectively testing whether the fire damper to be tested can normally perform its functions under different operating environments, effectively improving the actual testing efficiency of the equipment and reducing the actual testing cost;

[0045] Step 3, safety protection: The flowing gas flowing through the fire damper to be tested can be injected into the collection frame 202 through the extension frame 105, extension pipe 104 and side frame 102 on the other side, and finally injected into the existing exhaust gas purification equipment inside the gas collecting frame 201, thereby effectively preventing the generated exhaust gas emissions from affecting the surrounding environment, improving the actual use effect of the equipment, and enabling the equipment to efficiently perform its functions.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

6. A highly corrosion-resistant fire damper detection method, characterized in that: A highly corrosion-resistant fire damper detection system as described in claim 5 includes the following steps: S1. Adaptive installation: According to the actual specifications of the fire damper to be tested, the first installation frame (112) and the second installation frame (113) are replaced and selected to match the fire damper to be tested, and then the rotating linkage worm (110) is rotated so that the rotating linkage worm (110) can cooperate with the linkage worm wheel to drive the linkage shaft (121) to rotate, and then the rotating linkage shaft (121) cooperates with the linkage bevel gear to drive the movable threaded rod (119) to rotate, so that the rotating movable threaded rod (119) can adjust the position of the push piece (120) threadedly connected thereto in the horizontal direction, so that the push piece (120) can squeeze and push the movable block (117) during the position change process, and the sliding rod (116) slides through The movable block (117) enables the movable block (117) to move along the direction of the slide bar (116) between the push piece (120) and the corresponding installation strip (115), thereby facilitating the adjustment of the spacing between the movable block (117) and the fixed block (118), facilitating the stable connection between the fire damper to be tested and the replaced first installation frame (112) or the second installation frame (113), and then the linked worm (110) is rotated in the reverse direction, thereby moving the push piece (120) away from the movable block (117), so that the movable block (117) will not be squeezed by the push piece (120) to affect the connection effect between the fire damper to be tested and the first installation frame (112) or the second installation frame (113), thereby simulating the actual installation effect; S2. Simulation test: the existing waste gas purification equipment is arranged inside the gas collecting frame (201). When the air leakage of the fire damper to be tested is detected, the ignited combustibles are placed on the top of the combustion rack (218). At this time, the fan (204) is operated at a low speed, so that the flowing airflow generated by the operation of the fan (204) is injected into the air guide frame (205) under the obstruction of the first partition (203), and then a small amount of air is injected into the insulation frame (206), so that the combustibles cannot be fully burned, thereby generating more smoke, and at the same time, the smoke and heat Driven by the flowing airflow, the smoke is injected into the corresponding side pipe (103) and the extension pipe (104) through the insulation frame (206) and the conveying frame (212), and then flows through the fire damper to be detected through the corresponding extension frame (105) and the first installation frame (112) or the second installation frame (113). When the flowing air temperature reaches the set temperature of the fire damper to be detected, the connection between the two extension frames (105) is cut off, so that the smoke can only gather on one side of the fire damper to be detected. Then, by observing the connection between the fire damper to be detected and the first installation frame (1 12) or whether there is a large amount of smoke emitted at the connection between the second installation frame (113) and the second installation frame (113), so that the air leakage condition of the fire damper to be detected can be visually observed. After the fire damper to be detected is reset, the running speed of the fan (204) is increased, and at the same time, an appropriate amount of common acid-base solution or waste solution is injected into the space on one side of the second partition (207) through the injection pipe (210), so that a large amount of flowing air generated by the fan (204) can be injected into the insulation frame (206), so that the combustibles can be fully burned, thereby simulating the actual fire condition. At this time, the combustion frame (213) transfers the high temperature to the solution through the heat conduction plate (208) and the heat conduction sheet (209), thereby accelerating the evaporation of the solution, and then the evaporated solution follows the flowing air flow to flow through the fire damper to be detected. At the same time, the speed at which the flowing air flow temperature rises to a safe temperature can be reduced, so that the evaporated solution can fully contaminate the fire damper to be detected, until the flowing air flow temperature reaches the set safe temperature of the fire damper to be detected, so that it can be detected whether the fire damper to be detected can normally realize its due function under different operating environments; S3. Safety protection: The flowing gas passing through the fire damper to be tested can be injected into the collection frame (202) through the extension frame (105), the extension pipe (104) and the side frame (102) on the other side, and finally injected into the existing waste gas purification equipment inside the gas collection frame (201).
