Description

Technical Field

[0001] The present invention relates to the technical field of air purification and ventilation, and in particular to an intelligent self-cleaning air purification and ventilation fire-fighting device. Background Art

[0002] Intelligent self-cleaning air purification ventilation fire protection devices are usually equipped with intelligent sensors and control systems, which can monitor indoor air quality in real time and automatically adjust working mode, wind speed and other parameters according to the monitoring results. At the same time, the device can effectively remove tiny particles in the air through the built-in air filter and adsorption layer components, further improve the indoor environment and reduce the accumulation of pollutants in the room;

[0003] However, compared with the prior art, the following defects still exist in specific use:

[0004] 1. After capturing particulate matter, dust and other impurities in the air for a long time, the surface of the filter inside the device will gradually accumulate to form a thick impurity layer. This process not only seriously hinders the filter's efficiency in capturing subsequent impurities, but also leads to a significant increase in air circulation resistance, thereby affecting the purification performance and ventilation efficiency of the entire device. More seriously, when the filter is seriously clogged, it will also cause equipment failures, such as motor overheating, increased energy consumption and other problems, posing a threat to the service life of the equipment. At the same time, the adsorption material in the adsorption layer will gradually reach the saturation point of its adsorption capacity after adsorbing harmful gases, odors and other pollutants for a long time, resulting in a sharp drop in adsorption capacity, releasing the adsorbed pollutants back into the air, and having a negative impact on indoor air quality;

[0005] 2. In addition, in order to prevent the outside air or pollutants from flowing back into the room through the exhaust port, the existing air purification ventilation fire fighting device needs to design the exhaust duct into a shape with a certain degree of curvature. However, for the curved part of the exhaust duct, when the gas flows through the elbow, the change in the direction of the air flow will generate additional friction resistance and local resistance. These resistances will cause the gas flow speed to decrease, and the contact of the pipes at the curved part will cause the separation of the gas flow, forming vortices and eddies. These secondary flow phenomena will further increase the flow resistance. In addition, the flow of gas in the curved pipe will cause uneven pressure distribution. Usually, the pressure on the outside of the elbow is higher than that on the inside. This pressure difference will affect the exhaust efficiency of the exhaust duct and the overall performance of the device.

[0006] 3. Since the exhaust duct opening of the existing air purification ventilation fire-fighting device is fixed, the airflow will suddenly lose the restriction of the inner wall of the duct at the moment of leaving the duct opening, causing the airflow to diffuse freely in the space. This free diffusion is often uneven, which makes the airflow concentration in some areas too high, while other areas are relatively low, thus affecting the overall quality distribution of indoor air. During the diffusion process, the airflow will continuously exchange heat and momentum with the surrounding environment, causing the energy of the airflow to gradually dissipate. If the airflow diffuses unevenly, then part of the airflow energy may be dissipated prematurely, thereby reducing the energy efficiency of the entire device;

[0007] In view of this, the present invention proposes an intelligent self-cleaning air purification ventilation fire fighting device to make up for and improve the deficiencies of the prior art. Summary of the invention

[0008] In order to solve the above technical problems, the present invention provides an intelligent self-cleaning air purification ventilation fire fighting device to solve the technical problems raised in the above background technology.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is: an intelligent self-cleaning air purification ventilation fire fighting device, comprising an air conveyor, the output end of the air conveyor is connected to a pre-filter, the end of the pre-filter away from the air conveyor is connected to a gas pipeline, the outer wall of the gas pipeline is provided with an electric control self-replacement mechanism, and the output end of the gas pipeline is provided with a balanced airflow mechanism;

[0010] The electrically controlled self-replacement mechanism is used to ensure that the gas circulating inside the gas pipeline is in a continuously purified state;

[0011] The balanced airflow mechanism is used for balanced processing of the gas exhausted from the inside of the gas pipeline.

[0012] Furthermore, the electrically controlled self-replacement mechanism includes a placement bin which is sleeved on the outer wall of the gas pipeline, the inner cavity bottom of the placement bin is rotatably connected to an electric control panel, the upper surface of the electric control panel is fixedly connected to a gravity sensor, the outer wall of the gravity sensor is installed with a movable clamp, the end of the movable clamp away from the gravity sensor is fixedly connected to the inner wall of the placement bin, the outer wall of the electric control panel is fixedly connected to an adjustment frame, the end of the adjustment frame away from the electric control panel is installed with a disc filter, the outer wall of the gas pipeline is symmetrically slidably connected to a linkage valve, the outer wall of the electric control panel is fixedly connected to a magnetic rod, and the bottom wall of the placement bin is slidably connected to an adjustment magnetic sheet.

[0013] Furthermore, the electric control panel, the gravity sensor and the linkage valve are all electrically connected, and the linkage valve is initially in a closed state.

[0014] Furthermore, the movable clamp is composed of two L-shaped clamp strips, and the distance between the two L-shaped clamp strips is equal to the length of the diagonal line of the gravity sensor.

[0015] Furthermore, the positive pole surfaces of the magnetic rod and the adjusting magnetic sheet correspond to each other, the magnetic rod and the adjusting magnetic sheet are initially located in the same horizontal plane, and the adjusting magnetic sheet is in a cylindrical form as a whole.

[0016] Furthermore, the balanced airflow mechanism includes a guide plate group uniformly fixedly connected to the curved part of the air pipeline, the end of the air pipeline away from the pre-filter is connected to an outlet pipe, the inner wall of the outlet pipe is rotatably connected to a driving fan, the lower surface of the driving fan is fixedly connected to a threaded shaft, the outer wall of the threaded shaft is threadedly connected to a threaded ring, and the outer wall of the threaded ring is symmetrically fixedly connected to a diverter plate.

[0017] Furthermore, the guide plate group as a whole is composed of three arc-shaped plates, and the three arc-shaped plates are equidistantly distributed according to the curvature of the gas pipeline.

[0018] Furthermore, the end of the air outlet pipe close to the air pipeline is funnel-shaped with a narrow top and a wide bottom, a ball screw structure is formed between the threaded shaft and the threaded ring, and the threaded ring is initially located at the lower end of the threaded shaft.

[0019] Furthermore, the diverter plate is in the shape of a three-dimensional isosceles triangle as a whole, and the inner wall of the diverter plate close to the air outlet pipe is fixedly connected with a solid ball, and the diverter plate and the air outlet pipe are slidably connected via the solid ball.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) This device uses a built-in gravity sensor to monitor the weight change of the disc filter in real time. When the weight of the filter increases to a preset threshold due to the capture of impurities, the gravity sensor will automatically trigger the electric control panel to drive the adjustment frame to rotate 90 degrees, thereby cleverly realizing the automatic replacement of the disc filter inside the gas pipeline, and quickly restoring the unobstructed air flow without human intervention. First, this structural design ensures that the disc filter is always in the best working state, avoiding the problem of reduced capture efficiency due to the accumulation of impurity layers. Secondly, by replacing the clogged disc filter in time, the air circulation resistance is effectively reduced, and the ventilation efficiency and purification capacity of the overall equipment are improved. In addition, the automatic replacement mechanism also reduces the risk of equipment failure due to filter blockage, extends the service life of the equipment, and reduces the additional cost incurred due to fault repair;

[0022] The design of the two L-shaped clamps in the movable clamp provides a stable support for the gravity sensor. Since the spacing between the clamps precisely matches the diagonal length of the gravity sensor, this structure can ensure that the gravity sensor is subjected to a balanced force during the rotation process, thereby ensuring that the disc filter itself can be accurately rotated 90 degrees each time the disc filter is replaced. The precise rotation of 90 degrees ensures that the disc filter can be accurately moved to the next working position, avoiding positional offset or misalignment during the replacement of the disc filter, thereby ensuring that the originally blocked disc filter part is completely moved out of the working area while the unblocked disc filter part enters the working area, thereby maximizing the use efficiency of the disc filter;

[0023] According to the symmetry and geometric characteristics of the swastika shape of the adjustment frame itself, its center of mass and geometric center will be very close to the state of coincidence. This balance makes it possible for the adjustment frame to drive the disc filter to rotate without generating additional torque caused by the displacement of the center of mass, thereby reducing the vibration of the disc filter caused by the airflow when rotating, thereby ensuring the stability of the device operation. Compared with simple geometric shapes such as circles or squares, the swastika shape can more effectively reduce the problem of local stress concentration, thereby reducing the risk of fatigue and damage of components in long-term operation.

[0024] (2) The positive poles of the magnetic rod and the adjusting magnetic sheet in the device correspond to each other, and the magnetic rod and the adjusting magnetic sheet are initially at the same horizontal plane. Therefore, after the disc filter is automatically replaced many times, the magnetic rod will eventually move to the top of the adjusting magnetic sheet. At this time, based on the magnetic principle of like poles repelling each other, the adjusting magnetic sheet will slide out from the bottom of the storage bin. This timely warning reminds the staff that the disc filter inside the gas pipeline has been automatically replaced to the last one, thereby improving the replacement and anti-blocking process of the entire device to ensure the stable operation of the equipment. In addition, this design can automatically detect and prompt the replacement needs of the disc filter without frequent manual inspections.

[0025] The adjusting magnetic sheet is in the form of a cylinder as a whole. The outer wall of the adjusting magnetic sheet blocks the magnetic repulsion of the magnetic rod moving closer, effectively limiting the direction in which the adjusting magnetic sheet is subjected to the magnetic repulsion of the magnetic rod, so that the magnetic repulsion can only act on the adjusting magnetic sheet through the opening inside the cup cover when the two are in the same horizontal plane, thereby realizing the directional conduction of the magnetic repulsion. This design ensures that the adjusting magnetic sheet can move in a predetermined direction when receiving the repulsion, improves the accuracy and reliability of the movement, and effectively isolates the weak magnetic force generated between the two from affecting the rotation of the magnetic rod, thereby reducing unnecessary interference and avoiding malfunction or inaccurate positioning caused by weak magnetic force.

[0026] (3) The device distributes three arc-shaped plates equidistantly inside the curved part of the gas transmission pipeline according to the size of the curved part, thereby forming a uniform airflow channel. This design helps to reduce the turbulence and eddy currents generated by the airflow at the curved part, so that the airflow can pass through the curved part more smoothly, improving the flow efficiency and stability of the airflow. The curved part is an area with greater resistance during the flow of the airflow, and the design of the guide vane group can guide the airflow to flow along a predetermined path, reducing the friction and collision between the airflow and the inner wall of the pipeline, thereby reducing the resistance loss. This not only helps to improve the ventilation efficiency of the device, but also reduces power energy consumption. In addition, the guide vane group can also serve as a supporting structure inside the pipeline, which can enhance the structural stability of the curved part. Under the action of airflow impact and vibration, the guide vane group can disperse and alleviate the impact of these forces on the pipeline, reducing the risk of deformation or damage to the pipeline due to stress concentration;

[0027] (4) In order to solve the problem that the airflow suddenly loses the constraint of the inner wall of the gas transmission pipeline and diffuses freely, forming an irregular and uneven flow pattern, the device uses the special shape and arrangement of the splitter plate to enable the airflow to be precisely guided and controlled when it contacts and bypasses the tip position, and then periodically separates double rows of vortices with opposite rotation directions and regular arrangement on both sides. The formation of this vortex structure is a typical manifestation of the nonlinear dynamic behavior of the fluid. It enables the airflow to maintain an orderly and periodic flow state after flowing out of the pipeline, and through the guidance of the splitter plate, the airflow is effectively dispersed in all directions, avoiding the phenomenon of airflow concentration in certain areas in traditional designs, thereby ensuring the consistency of air quality in various areas of the room. On the other hand, since the airflow can maintain a certain order after flowing out of the pipeline, its momentum loss and heat exchange process are more controllable, avoiding the problem of premature energy dissipation caused by free diffusion.

The outer wall of the electric control panel 22 is fixedly connected with a magnetic rod 28, and the bottom wall of the placement bin 21 is slidably connected with an adjusting magnetic sheet 29. The electric control panel 22, the gravity sensor 23 and the linkage valve 27 are all electrically connected, and the linkage valve 27 is initially in a closed state. The movable clamp 24 is composed of two L-shaped clamp strips, and the spacing between the two L-shaped clamp strips is equal to the length of the diagonal of the gravity sensor 23. The positive pole surfaces between the magnetic rod 28 and the adjusting magnetic sheet 29 correspond to each other. The magnetic rod 28 and the adjusting magnetic sheet 29 are initially in the same horizontal plane, and the adjusting magnetic sheet 29 is cylindrical as a whole;

[0042] Specifically, the gravity sensor 23 automatically triggers the electric control panel 22 to drive the adjustment frame 25 to rotate 90 degrees, thereby cleverly realizing the automatic replacement of the disc filter 26 inside the gas pipeline 12, and quickly restoring the unimpeded air flow without manual intervention. First, this structural design ensures that the disc filter 26 is always in the best working state, avoiding the problem of decreased capture efficiency due to the accumulation of impurity layers. Secondly, by timely replacing the clogged disc filter 26, the air circulation resistance is effectively reduced, and the ventilation efficiency and purification capacity of the overall equipment are improved;

[0043] Please refer to Figure 7 - Fig. 9 As shown, the balanced airflow mechanism 3 includes a guide plate group 31 evenly fixedly connected to the curved part of the air delivery pipeline 12, and the end of the air delivery pipeline 12 away from the pre-filter 11 is connected to the outlet pipe 32, and the inner wall of the outlet pipe 32 is rotatably connected to the driving fan 33, and the lower surface of the driving fan 33 is fixedly connected to the threaded shaft 34, and the outer wall of the threaded shaft 34 is threadedly connected to the threaded ring 35, and the outer wall of the threaded ring 35 is symmetrically fixedly connected to the diverter plate 36. The guide plate group 31 as a whole is composed of three arc-shaped plate groups. The three arc-shaped pieces are equidistantly distributed according to the curvature of the gas pipeline 12. The end of the gas outlet pipe 32 close to the gas pipeline 12 is in a funnel shape that is narrow at the top and wide at the bottom. A ball screw structure is formed between the threaded shaft 34 and the threaded ring 35, and the threaded ring 35 is initially located at the lower end of the threaded shaft 34. The diverter plate 36 is a three-dimensional isosceles triangle as a whole. The inner wall of the diverter plate 36 close to the gas outlet pipe 32 is fixedly connected with a solid ball, and the diverter plate 36 and the gas outlet pipe 32 are slidably connected through the solid ball.

[0044] Specifically, through the special shape and arrangement of the splitter plate 36, the airflow is precisely guided and controlled when it contacts and bypasses the tip position, and then periodically separates two rows of vortices with opposite rotation directions and regular arrangement on both sides. The formation of this vortex structure is a typical manifestation of nonlinear dynamic behavior of the fluid, which enables the airflow to maintain an orderly and periodic flow state after the gas pipeline 12, and through the guidance of the splitter plate 36, the airflow is effectively dispersed in all directions, avoiding the phenomenon of airflow being concentrated in certain areas in the traditional design;

[0045] The following are the complete usage steps and working principles of the above embodiment:

[0046] The electric control self-replacement mechanism 2 for ensuring that the gas flowing inside the gas pipeline 12 is in a continuously purified state is specifically used as follows:

[0047] like Figure 3 and Figure 4 As shown, the disc filter 26 is initially located inside the gas pipeline 12, and the linkage valve 27 is in a closed state, thereby ensuring that the external airflow can normally flow through the air conveyor 1 and the pre-filter 11 to the inside of the gas pipeline 12. As the equipment continues to operate, pollutants such as dust and particulate matter in the air will gradually accumulate on the surface of the disc filter 26. As time goes by, the pores on the surface of the disc filter 26 that allow airflow to pass through will gradually decrease, and then gradually form an impurity layer on its surface, causing it to be blocked;

[0048] like Figure 5 As shown, since the electric control panel 22, the gravity sensor 23 and the linkage valve 27 are all electrically connected, when the weight of the disc filter 26 increases due to the accumulation of impurities on its surface, the gravity sensor 23 monitors the weight change of the disc filter 26 in real time. When the weight of the filter increases to a preset threshold due to the capture of impurities, the electric control panel 22 first controls the linkage valve 27 to change it from an initial closed state to an open state. Then, as the linkage valve 27 contracts, the gravity sensor 23 drives the electric control panel 22 to rotate, thereby causing the adjustment frame 25 and the disc filter 26 to rotate within a certain range in the gas pipeline 12.

[0049] Since the spacing between the clamping strips in the movable clamp 24 accurately matches the diagonal length of the gravity sensor 23, a stable support is provided for the gravity sensor 23. This structure can ensure that the gravity sensor 23 is subjected to a balanced force during the rotation process, thereby ensuring that each time the adjustment frame 25 is triggered to rotate and replace the disc filter 26, the disc filter 26 itself can accurately rotate 90 degrees. The accurate rotation of 90 degrees ensures that the disc filter 26 can accurately move to the next working position, avoiding positional deviation or misalignment during the replacement process of the disc filter 26.

[0050] like Figure 6 As shown, since the magnetic rod 28 is fixedly connected to the outer wall of the electric control panel 22, when the electric control panel 22 keeps rotating, the magnetic rod 28 will rotate synchronously with it. Since the positive pole surfaces of the magnetic rod 28 and the adjusting magnetic sheet 29 correspond to each other, and the magnetic rod 28 and the adjusting magnetic sheet 29 are initially in the same horizontal plane, after the electric control panel 22 drives the disc filter 26 to be automatically replaced for many times, the magnetic rod 28 will eventually move to the top of the adjusting magnetic sheet 29. At this time, based on the magnetic principle that like poles repel each other, the adjusting magnetic sheet 29 will be repelled by the magnetic force of the magnetic rod 28 and then slide out from the bottom of the storage bin 21. This timely warning reminds the staff that the disc filter 26 inside the gas pipeline 12 has been automatically replaced to the last one, and it needs to be replaced and repaired as a whole in time.

[0051] The balanced airflow mechanism 3 for balanced processing of the gas exhausted from the gas pipeline 12 is specifically used as follows:

[0052] like Figure 7 and Figure 8 As shown, the guide vane group 31 is integrally installed at the curved part of the gas pipeline 12, and the guide vane group 31 is composed of three arc-shaped pieces, and the three arc-shaped pieces are equidistantly distributed according to the curvature of the gas pipeline 12. Therefore, when the airflow passes through the guide vane group 31, a uniform airflow channel can be formed by the distribution of the arc-shaped pieces, thereby reducing the turbulence and eddy current generated by the airflow at the curved part, so that the airflow can pass through the curved part more smoothly, thereby improving the flow efficiency and stability of the airflow;

[0053] like Figure 8 and Fig. 9 As shown, since the driving fan 33 is rotatably connected to the inner wall of the air outlet pipe 32, and the driving fan 33 is located at the output end of the gas pipeline 12, when the gas pipeline 12 is in a normal exhaust state, when the airflow blows toward the blades of the driving fan 33, the airflow will contact the surface of the blades and exert a force in the opposite direction but equal in magnitude. This wind force acts on the surface of the blades and pushes the blades to rotate. According to Newton's third law, the blades will also generate a force of equal magnitude but opposite direction to the wind, that is, the wind force will be pushed in the opposite direction by the blades. This action and reaction force causes the driving fan 33 to rotate as a whole.

[0054] Since the threaded shaft 34 is fixedly connected to the lower surface of the driving fan 33, the threaded shaft 34 will rotate synchronously with the driving fan 33, and a ball screw structure is formed between the threaded shaft 34 and the threaded ring 35. Therefore, during the rotation of the threaded shaft 34, the threaded shaft 34 will drive the threaded ring 35 to make the solid ball fixedly connected through the outer wall move back and forth along the inner wall of the outlet pipe 32. Since the diverter plate 36 is a three-dimensional isosceles triangle as a whole, and the tip position of the diverter plate 36 corresponds to one end of the gas output of the gas pipeline 12, when the airflow contacts and bypasses the tip position, it will be precisely guided and controlled, and then double rows of vortices with opposite rotation directions and regular arrangement will be periodically separated on both sides. The formation of this vortex structure is a typical manifestation of nonlinear dynamic behavior of the fluid. It enables the airflow to maintain an orderly and periodic flow state after flowing out of the pipeline, thereby avoiding the phenomenon of airflow concentration in certain areas in traditional designs, thereby ensuring the consistency of air quality in various indoor areas.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
