Description

Technical Field

[0001] The present invention relates to the technical field of ventilation equipment for civil air defense projects, and in particular to a cleaning device for ventilation equipment for civil air defense projects. Background Art

[0002] Ventilation technology for civil air defense projects refers to the installation of ventilation facilities in civil air defense projects to allow air to circulate and provide people with a fresh and comfortable air environment. In air defense projects, ventilation facilities are an indispensable part that can refresh the air inside the air defense projects, reduce the accumulation of thick smoke and toxic gases, and thus ensure people's safety.

[0003] Civil air defense project ventilators are commonly used ventilation equipment in existing civil air defense projects. Through the effective setting of civil air defense project ventilators, the safety of civil air defense projects has been greatly improved. However, the existing civil air defense project ventilators still have the following problems during use: the outer shell of the civil air defense project ventilator is mostly one-piece molded, welded or bolted, and the motor, impeller and other auxiliary components are all arranged inside it. The interior of the outer shell is relatively deep and it is inconvenient to open it from the outside. This makes the maintenance and cleaning of the motor, impeller and other auxiliary components in the outer shell particularly troublesome, time-consuming and labor-intensive, and poor to use.

[0004] The patent with announcement number CN221033301U discloses a mine ventilation device, comprising a shell, the inner rear end of the shell is fixedly connected to a rear bracket, the rear end of the rear bracket is fixedly installed with a motor, the output shaft of the motor passes through the rear bracket and is fixedly connected to a transmission rod, a plurality of impellers are fixedly connected around the transmission rod, a fan control switch is fixedly installed on an outer wall of one side of the rear end of the shell, and the motor is electrically connected to the fan control switch; a sliding cover is provided at the upper end of the shell, and slots are provided on both sides of the front end and bottom end of the sliding cover, and the slots are connected to the shell by snapping, and a card hole is provided on the upper front end of the sliding cover; a fixed block is fixedly connected to the upper front end of the shell, and the sliding cover on the shell in the patent can be slid and removed to expose the internal structure of the shell, greatly increasing the visual range and operating space, so as to facilitate the maintenance and cleaning of the internal structure of the shell, which is simple and convenient and has better use.

[0005] However, the cleaning process of the above-mentioned ventilator still needs to be done manually, which not only increases the workload of the operation and maintenance personnel, but may also cause incomplete cleaning or untimely maintenance due to human factors, thereby affecting the operating efficiency and service life of the ventilator. In addition, if the disassembly and assembly are improper during the manual cleaning process, it may cause secondary damage to the equipment and even cause safety hazards.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be the common meanings understood by people with ordinary skills in the field to which the present invention belongs. The words "including" and similar words used in this article mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0020] In response to the problems existing in the prior art, an embodiment of the present invention provides a cleaning device for ventilation equipment of civil air defense projects. The pipeline in the cleaning device for ventilation equipment of civil air defense projects adopts a three-section L-structure, in which the vertical pipe 1 and the horizontal pipe 2 are arranged perpendicular to each other, and the vertical pipe 1 is arranged vertically and the horizontal pipe 2 is arranged horizontally. In this way, when the fan is working, the wind can move from bottom to top, and the dust is blocked by the filter part 4 and prevented from entering the horizontal pipe 2; and, under the action of the dust's own gravity, it can fall downward and break away from the vertical pipe 1, avoiding deposition in the vertical pipe 1 or depositing a smaller amount.

[0021] Specifically, if Figure 1 As shown, the cleaning device for the ventilation equipment of the civil air defense project includes: The vertical pipe 1 is arranged vertically. Figure 1 In the example, it can be understood that the ventilator device is a bottom view viewed from the bottom up.

[0022] And the fan part 3 is arranged at the bottom of the vertical tube 1. When working, the fan part 3 draws air from the bottom of the vertical tube 1 for ventilation.

[0023] The horizontal tube 2 is connected to the end of the arc tube 7 away from the vertical tube 1. The horizontal tube 2 and the vertical tube 1 are arranged perpendicular to each other, and the vertical tube 1 is arranged in the vertical direction; the arc tube 7 is used to connect the horizontal tube 2 and the vertical tube 1.

[0024] The filter unit 4 is disposed within the vertical tube 1 and between the fan unit 3 and the arc tube 7. The filter unit 4 can filter the gas moving upward from the bottom to remove dust or other solid particles. In one example, the filter unit 4 can be a filter mesh, but is not limited to a filter mesh.

[0025] The cleaning part 5 is provided in the vertical pipe 1 , and moves synchronously with the fan part 3 , and is used to scrape and clean the sediment deposited on the inner wall of the vertical pipe 1 and the lower surface of the filter part 4 .

[0026] Compared with the cleaning mode in the prior art, which requires the ventilator to be disassembled and assembled, the improvement of this device can achieve the effects of high-efficiency cleaning and timely cleaning. At the same time, it can avoid secondary damage to the ventilator during disassembly and assembly. Specifically, the present invention can clean the dust in a three-stage cleaning process. First, the vertical tube 1 is set vertically to prevent as little dust as possible from being deposited on the inner wall of the vertical tube 1. When the fan unit 3 is shut down, the dust falls to the outside of the vertical tube 1 under the action of its own gravity; then the filter unit 4 cleans the air moving upward to remove dust or other solid particles in the air to ensure the cleanliness of the air; finally, the cleaning unit 5 works as the fan unit 3 works, and can scrape off the sediment deposited on the inner wall of the vertical tube 1 and the lower surface of the filter unit 4. This can achieve a better cleaning effect and ensure the cleanliness of the equipment on the one hand, and on the other hand, it can prevent dust from blocking the filter unit 4 and ensure the high-efficiency filtering performance of the filter unit 4.

[0027] In one embodiment, Figure 1 As shown, the fan unit 3 includes: The support pipe 31 is installed on the bottom of the vertical pipe 1 , and the support pipe 31 and the vertical pipe 1 are connected to each other, ensuring that air can move upward from the support pipe 31 into the vertical pipe 1 .

[0028] A motor 32 is installed in the support tube 31 through a support plate 33, and a fan blade 34 is installed on the driving end of the motor 32; when working, the motor 32 will cause the fan blade 34 to rotate, and the rotation of the fan blade 34 will draw air into the vertical tube 1, and enter the horizontal tube 2 through the filter part 4, and finally enter the civil defense project through the horizontal tube 2.

[0029] In one embodiment, Figure 1 As shown, the cleaning unit 5 includes: The first cleaning component 51 is slidably arranged with the inner wall of the vertical tube 1 and is used to clean the sediment deposited on the inner wall of the vertical tube 1; when set, the first cleaning component 51 is matched with the vertical tube 1.

[0030] One end of the connecting plate 52 is disposed on the first cleaning assembly 51 , and the other end of the connecting plate 52 is disposed on the driving end of the motor 32 .

[0031] The second cleaning assembly 53 is provided on the first cleaning assembly 51. The second cleaning assembly 53 and the lower surface of the filter 4 are slidably arranged relative to each other and are used to clean sediment deposited on the lower surface of the filter 4. The second cleaning assembly 53 and the filter 4 are matched with each other.

[0032] In one embodiment, Figure 2 As shown, the first cleaning component 51 includes: The first cleaning plate 511 is slidably arranged on the inner wall of the vertical tube 1, and the first cleaning plate 511 is connected to the connecting plate 52; the first cleaning plate 511 has an arc-shaped structure, and the curvature is consistent with the curvature of the inner wall of the vertical tube 1; in the specific setting, the first cleaning plate 511 and the inner wall of the vertical tube 1 are installed in close contact with each other. The purpose of such a setting is to first ensure that there is no gap between the vertical tube 1 and the first cleaning plate 511 to prevent dust from entering; then, during the rotation of the first cleaning plate 511, the dust deposited on the inner wall of the vertical tube 1 can be better scraped off.

[0033] The second cleaning plate 512 is provided at the end of the arc direction of the first cleaning plate 511, and the second cleaning plate 512 is slidably connected to the inner side wall of the vertical tube 1. There are two second cleaning plates 512, which are respectively provided at the two ends of the first cleaning plate 511. Figure 2 In the example, the second cleaning plate 512 is provided on both ends of the first cleaning plate 511, thereby ensuring that the first cleaning plate 511 can scrape off the sediment when rotating counterclockwise or clockwise. The second cleaning plate 512 adopts an arc-shaped structure, and the curvature of the second cleaning plate 512 is consistent with the curvature of the inner side wall of the vertical tube 1. In one example, the second cleaning plate 512 adopts a blade-shaped structure, so that the scraped sediment can be pushed away from the vertical tube 1, thereby falling from the lower end of the vertical tube 1 to the outside of the vertical tube 1 under the action of its own gravity.

[0034] It is worth noting that the lower ends of the first cleaning plate 511 and the second cleaning plate 512 are in contact with and slidably connected to the filter portion 4, as shown in FIG. Figure 3 Example shown.

[0035] In one embodiment, Figure 3 As shown, the second cleaning component 53 includes: The third cleaning plate 531 is fixedly mounted on the first cleaning plate 511 and is slidably connected to the lower surface of the filter portion 4. The third cleaning plate 531 and the filter portion 4 are configured to match each other. The rotation of the first cleaning plate 511 causes the third cleaning plate 531 to rotate, and the rotation of the third cleaning plate 531 scrapes off sediment deposited on the upper surface of the filter portion 4. The structural design of the present invention is reasonable. While the first cleaning plate 511 is scraping off sediment on the inner side wall of the vertical tube 1, the third cleaning plate 531 also simultaneously cleans sediment deposited on the filter portion 4.

[0036] The fourth cleaning plate 532 is slidably connected to the lower surface of the filter portion 4 and is slidably connected to the side wall of the first cleaning plate 511. The fourth cleaning plate 532 and the third cleaning plate 531 are slidably arranged on the end of the arc-shaped direction of the third cleaning plate 531. Specifically, the fourth cleaning plate 532 also adopts a blade structure similar to that of the second cleaning plate 512. There are also two fourth cleaning plates 532, which are respectively arranged on the left and right ends of the third cleaning plate 531. Figure 3 and Figure 4 Example shown.

[0037] In one embodiment, Figure 4 As shown, the cleaning device for the ventilation equipment of the civil air defense project also includes a disassembly and assembly part 6. The setting of the disassembly and assembly part 6 can enable the third cleaning plate 531 and the fourth cleaning plate 532 to be disassembled and assembled, and the structural design of the disassembly and assembly part 6 is reasonable, which can achieve convenient and efficient disassembly and assembly of the third cleaning plate 531 and the fourth cleaning plate 532. Specifically, first determine to install the third cleaning plate 531 and the filter part 4, and then install the third cleaning plate 531 and the fourth cleaning plate 532 through the disassembly and assembly part 6. The equipment after installation is embodied in that the third cleaning plate 531 and the fourth cleaning plate 532 are arranged to fit each other, and the third cleaning plate 531 and the fourth cleaning plate 532 are arranged to slide against the filter part 4. The purpose of such arrangement can achieve a better and more efficient cleaning effect.

[0038] Specifically, the disassembly and assembly portion 6 includes: The connecting plate 61 is fixedly mounted on the side wall of the fourth cleaning plate 532; The fixing screws 62 are threadedly inserted into the connecting plate 61 and the third cleaning plate 531 , and the fixing screws 62 are used for fixed connection between the connecting plate 61 and the third cleaning plate 531 .

[0039] During operation, the connecting plate 61 connects the two fourth cleaning plates 532 to form an inverted U-shaped structure, and the U-shaped structure is buckled onto the outside of the third cleaning plate 531 from top to bottom. When the lower end of the U-shaped structure contacts the upper surface of the filter portion 4, the fixing screw 62 is screwed to fix the connecting plate 61 and the third cleaning plate 531 together, thereby fixing the third cleaning plate 531 and the fourth cleaning plate 532 together.

[0040] In one embodiment, Figure 4 As shown, the disassembly and assembly portion 6 further includes: The guide groove 63 is formed on the third cleaning plate 531 . The guide plate 64 is provided on the side wall of the fourth cleaning plate 532 . The guide plate 64 is slidably disposed in the guide groove 63 .

[0041] In this example, the guide groove 63 and the guide plate 64 can not only play the role of guiding support, making the installation process of the third cleaning plate 531 and the fourth cleaning plate 532 more efficient and accurate; they can also play the role of supporting positioning. When the guide plate 64 moves downward and contacts the bottom wall of the guide groove 63, the guide plate 64 stops moving downward. At this time, the docking of the third cleaning plate 531 and the fourth cleaning plate 532 is completed, and then the third cleaning plate 531 and the fourth cleaning plate 532 can be fixed together by the fixing screws 62, and the position after installation can be guaranteed to be accurate.

[0042] In one embodiment, Figure 5 and Figure 6 As shown, the cleaning device for ventilation equipment of civil air defense engineering further includes a counter-impact portion 8 provided in the vertical pipe 1, and the counter-impact portion 8 is used to provide a downward counter-impact force when the motor 32 stops, so as to flush the sediment out of the vertical pipe 1 to achieve the cleaning process. The counter-impact portion 8 includes: The fixed tube 81 is fixedly arranged on the inner wall of the vertical tube 1, and the fixed tube 81 is arranged between the filter part 4 and the arc tube 7. The inner wall of the fixed tube 81 is provided with an air discharge groove 82; the anti-impact plug 83 is movably plugged in the fixed tube 81; the support plate 85 is fixedly arranged on the inner wall of the vertical tube 1; the elastic component 84 is arranged between the anti-impact plug 83 and the support plate 85, and is used for the fixed connection between the anti-impact plug 83 and the support plate 85, and the elastic component 84 provides a downward anti-impact force for the anti-impact plug 83.

[0043] During operation, the motor 32 rotates with the fan blades 34, which attracts air to move downward through the filter unit 4. Figure 5As shown in the example; the downward-moving air will enter the fixed tube 81 and push the anti-shock plug 83 in the fixed tube 81 to move downward. The continuous downward movement of the anti-shock plug 83 will cause the top of the anti-shock plug 83 to move to the bottom of the air discharge groove 82. At this time, the air will pass through the air discharge groove 82, over the anti-shock plug 83, and move to the outside of the fixed tube 81 and enter the horizontal tube 2; in this process, the elastic component 84 is compressed; when the motor 32 stops, it will stop delivering air downward, and the downward resistance to the anti-shock plug 83 will be lost. At this time, under the elastic reset force of the elastic component 84, the anti-shock plug 83 will be pushed upward to achieve the re-blocking of the air discharge groove 82. As the anti-shock plug 83 continues to move upward, it will push the air in the fixed tube 81 upward, generating a reverse impact force. The existence of this impact force will impact the dust or particulate matter in the vertical tube 1 or on the surface of the filter part 4 to the outside of the vertical tube 1, thereby ensuring that the vertical tube 1 always remains clean.

[0044] In one embodiment, Figure 6 As shown, the elastic component 84 includes: The elastic rod 841 is arranged on the anti-impact plug 83; the elastic tube 842 is arranged on the support plate 85, and the elastic rod 841 is movably inserted into the elastic tube 842; the spring 843 is wound around the outside of the elastic rod 841, and the two ends of the spring 843 are respectively connected to the side wall of the elastic rod 841 and the outer side wall of the elastic tube 842.

[0045] The setting of this example can provide a reset impact force for the counter-shock plug 83. Specifically, when the counter-shock plug 83 moves downward, the elastic rod 841 will move into the elastic tube 842. At this time, the spring 843 is compressed. When the counter-shock plug 83 loses the downward air impact force, the reset force of the spring 843 will carry the elastic rod 841 upward relative to the elastic tube 842, thereby providing the reset force of the spring 843 to provide an upward counter-shock force for the counter-shock plug 83.

[0046] In one embodiment, Figure 7 As shown, the cleaning device for ventilation equipment in civil air defense projects further includes a pushing portion (not shown) provided between the anti-impact plug 83 and the supporting plate 85. The pushing portion is used to assist the elastic component 84 in providing a counter-impact force to the anti-impact plug 83. The pushing portion includes: The first magnet 9 is provided on the anti-impact plug 83; the second magnet 10 is provided on the supporting plate 85, and the second magnet 10 and the first magnet 9 have the same magnetic pole on the side close to each other, and there is a repulsive force between the second magnet 10 and the first magnet 9.

[0047] Since there is a repulsive force between the second magnet 10 and the first magnet 9, during the movement of the back-impact plug 83 toward the support plate 85, the second magnet 10 and the first magnet 9 will get closer and closer, and the repulsive force will become greater and greater. In this way, when the back-impact plug 83 loses the downward resistance of the air, the repulsive force between the second magnet 10 and the first magnet 9 and the reset elastic force of the elastic component 84 will realize an instantaneous back-impact effect on the back-impact plug 83, so that the back-impact plug 83 has an instantaneous recoil force. The existence of the recoil force will impact all the dust suspended in the vertical pipe 1 or the sediment cleaned by the cleaning part 5 to the outside of the vertical pipe 1, thereby realizing the cleaning of the vertical pipe 1 and ensuring that the vertical pipe 1 remains clean.

[0048] While embodiments of the present invention have been described in detail above, it will be apparent to those skilled in the art that various modifications and variations of these embodiments are possible. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention. Furthermore, the invention described herein is susceptible to other embodiments and may be practiced or implemented in a variety of ways.
