Description

Technical Field

[0001] The present application relates to the technical field of air purification, and in particular to a medical building purification and sterilization system. Background Art

[0002] Hospital buildings have high requirements for indoor air quality. They need to control the indoor temperature, humidity, cleanliness, indoor pressure, etc. within a certain range, and reduce the pollutants such as particulate matter, harmful gases, bacteria, etc. in the indoor air to below the specified indicators, so as to reduce the risk of cross infection among patients and protect the health of medical staff. Therefore, it is necessary to build a purification and sterilization system inside the medical building. The purification and sterilization system is mainly composed of air conditioning units and various pipes for driving air circulation. The air conditioning unit has multiple functional units inside, which can effectively control the indoor temperature, humidity and cleanliness, and sterilize and disinfect the air supplied to the room.

[0003] At present, the relevant technology discloses an integrated fresh air supply air conditioning unit, in which the interior of the air conditioning unit is sequentially divided into a mixing section, a fan section, a flow equalization section, a filtering section, a control section and a sterilization section, wherein the side wall of the mixing section is provided with a fresh air inlet and a return air inlet respectively; the external fresh air can enter the mixing section through the fresh air inlet, and the air in the medical room can also enter the mixing section through the return air duct and the return air inlet, thereby ensuring fresh indoor air. Compared with the traditional split air conditioning unit, the integrated fresh air supply air conditioning unit has a series of advantages such as saving installation space, reducing energy consumption, energy saving and environmental protection.

[0004] However, due to the compact internal functional units of the integrated air-conditioning unit, when the air-conditioning unit fails during use and needs to be shut down for maintenance, a large number of parts need to be disassembled, which takes more time than the maintenance of traditional split air-conditioning units. For medical rooms with frequent personnel flow or high requirements for sterile environment, the inability to quickly repair the air-conditioning unit may have adverse effects on indoor personnel, such as rapid bacterial growth and infection; and if the backup purification equipment system is temporarily activated, it will increase energy consumption, which violates the original intention of energy saving of the integrated purification system. Therefore, how to quickly repair the air-conditioning unit when it fails has become an urgent problem that hospitals need to solve. Summary of the invention

[0005] Based on this, the present application provides a medical building purification and sterilization system, which can quickly repair the functional units inside the purification air-conditioning unit when they fail, shorten the maintenance time, and reduce the possibility of personnel infection due to bacterial growth.

[0006] The medical building purification and sterilization system provided in this application adopts the following technical solutions:

[0008] A mixing chamber is arranged inside the cabin assembly, and a fresh air inlet and a return air inlet are arranged in the cabin assembly, and the fresh air inlet and the return air inlet are respectively connected to the mixing chamber; an air supply outlet is arranged on a side of the cabin assembly away from the return air inlet;

[0009] There are multiple groups of mobile devices arranged inside the cabin assembly, and the fan unit, filter unit, temperature control unit and humidity control unit are installed in each group of mobile devices respectively; among them,

[0010] The moving device includes a moving platform slidably arranged inside the cabin assembly, a locking mechanism installed on the moving platform, and a limiting component fixed inside the cabin assembly, the limiting component includes a base fixed to the cabin assembly and a blocking seat fixed to the base, in a locked state, the moving platform abuts against the blocking seat, and the base is located below the moving platform;

[0011] The mobile platform is slidably mounted with a positioning piece, the positioning piece is located outside the base, and the base is provided with a positioning groove adapted to be plugged with the positioning piece; the locking mechanism is used to force the positioning piece to be plugged into the positioning groove.

[0012] By adopting the above-mentioned technical solution, the medical building purification and sterilization system of the present application, by setting a mobile device between each group of functional units such as the fan unit, the filter unit, the temperature control unit and the humidity control unit and the cabin assembly, when a functional unit fails, the corresponding locking mechanism is unlocked, and the mobile platform can be easily pulled to the outside of the cabin assembly to perform rapid maintenance of the corresponding functional unit, thereby reducing the labor intensity of the maintenance personnel and shortening the maintenance time. When the maintenance is completed, the mobile platform is pushed back into the cabin assembly, and the mobile platform can be quickly positioned by the positioning member, and then the locking mechanism is controlled to force the positioning member to be inserted into the positioning groove, so that the maintenance operation of the functional unit can be quickly completed, the overall maintenance cycle is short, and the rapid growth of bacteria in the medical room can be reduced, and the possibility of bacterial infection of personnel can be reduced.

[0013] Optionally, the mobile platform includes a base plate and a side plate portion arranged at a bottom edge of the base plate, and an extension direction of the side plate portion is arranged in the same direction as a sliding direction of the mobile platform;

[0014] A mounting seat is fixed on the side of the side plate close to the base, and the positioning piece is movably inserted into the side plate and the mounting seat; a first spring is provided between the positioning piece and the mounting seat, and the first spring is used to force the positioning piece to be normally exposed to the mobile platform, at which time one end of the positioning piece close to the base is completely retracted into the mounting seat.

[0015] By adopting the above-mentioned technical solution, the setting of the first spring can always force the end of the positioning member away from the base to be exposed on the mobile platform. At this time, the end of the positioning member close to the base can be completely retracted into the installation groove, thereby reducing the possibility of interference between the positioning member and the base when the mobile platform is pushed back into the cabin assembly; after the mobile platform abuts against the stop seat, the locking mechanism can be controlled to force the positioning member to match and be inserted into the positioning groove, so as to firmly position the mobile platform.

[0016] Optionally, the locking mechanism includes a movable arm plate rotatably connected to the side of the mobile platform and a fixed column fixed to the side of the mobile platform. The movable arm plate is provided with a hook portion for hooking and positioning with the fixed column and an abutting portion for abutting with the positioning piece. When the hook portion is hooked and positioned with the fixed column, the abutting portion abuts against the positioning piece and forces the positioning piece to move inward.

[0017] By adopting the above-mentioned technical solution, after the mobile platform is pushed into the interior of the cabin assembly and abuts against the blocking seat, the movable arm plate can be positioned by rotating the movable arm plate so that the hooking portion of the movable arm plate and the fixed column are hooked with each other; at this time, the abutting portion of the movable arm plate can abut against the positioning piece and force the positioning piece to be inserted into the positioning groove, so as to achieve stable positioning of the mobile platform.

[0018] Optionally, the mobile device further includes a positioning and holding mechanism disposed between the mobile platform and the limiting component, the positioning and holding mechanism including a connecting column, a first rotating wheel, a hinged column and a second rotating wheel, the connecting column is fixed to the mobile platform, and the first rotating wheel is rotatably connected to the connecting column;

[0019] There are two hinged columns, which are respectively hinged to the blocking seat and are symmetrically arranged; a torsion spring is provided at the hinge position of the hinged column and the blocking seat, and the torsion spring is used to force the hinged column to rotate in a direction close to the other hinged column;

[0020] There are two second rotating wheels, which are rotatably connected to the ends of the two hinged columns respectively. In the locked state, the first rotating wheel is located between the second rotating wheel and the blocking seat, and the two second rotating wheels are pressed against the first rotating wheel together.

[0021] By adopting the above-mentioned technical solution, in the locked state, that is, the mobile platform is in contact with the abutment and locked by the locking mechanism, the second rotating wheel can be pressed against the first rotating wheel under the torsion force of the torsion spring, so that the two second rotating wheels can jointly clamp and position the first rotating wheel, thereby further improving the connection stability of the mobile platform after being locked; and, when the maintenance personnel complete the maintenance work and push the mobile platform back into the cabin assembly, the two second rotating wheels can be used to initially clamp and position the first rotating wheel, so that the maintenance personnel can free their hands and operate the locking mechanism to lock and position the mobile platform.

[0022] Optionally, a baffle is fixed inside the cabin assembly, and a mixing chamber is formed between the baffle and the inner wall of the cabin assembly; the baffle is provided with a through vent;

[0023] The fan unit includes a sliding seat slidably arranged on the mobile platform and a fan component fixed to the sliding seat. Two guide columns are fixedly mounted on the top of the mobile platform. The two guide columns are arranged side by side, and the axial direction of the guide columns is perpendicular to the moving direction of the mobile platform.

[0024] The two guide columns are slidably connected to a sliding rod, and the sliding seat is slidably connected to the sliding rod; a linkage mechanism is provided between the sliding seat and the cabin assembly to enable the fan component to automatically abut against the vent after the mobile platform is pushed and locked on the limiting component.

[0025] By adopting the above technical solution, a baffle is set to separate and form a mixing chamber, and the external fresh air and the return air in the medical room can be mixed inside the mixing chamber and sent to the next functional unit through the fan unit. In addition, the fan component is slidably connected to the mobile platform through a sliding seat. When the maintenance personnel complete the maintenance work and push the mobile platform back into the cabin assembly, the linkage component can automatically force the sliding seat to move along the guide column and toward the baffle. Finally, after the mobile platform is locked in the limit component, the fan component can automatically fit the vent to facilitate normal air supply of the fan component.

[0026] Optionally, the linkage mechanism includes a rotating member, a movable plug rod and a second spring, wherein the rotating member is fixed with a rotating shaft, and the rotating shaft is rotatably connected to the mobile platform;

[0027] The rotating member is provided with plug holes passing through on both sides, and the movable plug rod is movably inserted in the plug holes; a connecting block is fixed at one end of the movable plug rod, and the connecting block is rotatably connected to the sliding seat; a second spring is arranged between the rotating member and the connecting block, and is used to force the connecting block to move in a direction away from the rotating member;

[0028] The linkage mechanism also includes a transmission component arranged between the rotating shaft and the cabin assembly. In the maintenance state, the sliding seat is located at the end of the sliding rod away from the stop seat, and the fan component is located at the side edge of the moving platform away from the stop seat; when the moving platform is pushed into the cabin assembly, the transmission component forces the rotating shaft to rotate, the sliding seat slides along the axial direction of the sliding rod, and then the sliding rod slides along the axial direction of the guide column.

[0029] By adopting the above-mentioned technical solution, in the locked state, the fan component is against the vent. When a fault occurs during the operation of the air-conditioning unit, the maintenance personnel pull the mobile platform outward, and use the transmission assembly to drive the rotating shaft and the rotating part to rotate together, so that the direction of the movable plug rod changes and rotates; due to the elastic force generated by the second spring acting on the connecting block, the rotation of the movable plug rod can keep the connecting block against the end of the sliding rod and move together with the sliding rod in the direction away from the baffle plate, so that the fan component automatically detaches from the vent.

[0030] After the sliding rod moves to the extreme position where the guide column is away from the baffle plate, the rotating part drives the movable plug rod to continue to rotate. At this time, the sliding rod can no longer move, and the sliding seat can slide along the axial direction of the sliding rod and in the direction away from the stop seat, thereby driving the fan component to move in the direction away from the stop seat; finally, the fan component can stay on the side edge of the mobile platform away from the stop seat, so as to facilitate maintenance personnel to inspect or maintain the fan unit.

[0031] Optionally, the transmission assembly includes a rack plate fixed to the inner bottom wall of the cabin assembly and a transmission gear fixedly connected to the rotating shaft. When the mobile platform is pushed into the cabin assembly, the transmission gear engages with the rack plate for transmission.

[0032] By adopting the above-mentioned technical solution, when the mobile platform is pulled outward or pushed inward, the transmission gear fixed to the rotating shaft can engage with the rack plate, and then the transmission gear can rotate naturally during the movement of the mobile platform, so as to drive the fan component to automatically move to abut against the vent, or automatically move to the side edge of the mobile platform away from the abutment seat, so as to facilitate inspection and maintenance.

[0033] Optionally, the cabin assembly is configured as a single-sided open structure, and a hatch for opening and closing is hinged on the open side of the cabin assembly, and the hinge position between the hatch and the cabin assembly is located at the top edge of the hatch; there are multiple hatches, and the hatches are arranged in sequence along the extension direction of the cabin assembly, and a buffer mechanism for slowing down the opening and closing speed is provided between each hatch and the cabin assembly.

[0034] By adopting the above-mentioned technical solution, the setting of the cabin door can form an enclosed space with the cabin assembly to facilitate the normal flow of air inside the cabin assembly; when a functional unit inside the air-conditioning unit fails, the cabin door is opened and the corresponding functional unit is pulled to the outside of the cabin assembly by a moving device, so that the faulty functional unit can be easily inspected or maintained.

[0035] Optionally, the buffer mechanism includes a gas spring, one end of which is rotatably connected to the cabin assembly, and the other end of which is rotatably connected to the cabin door.

[0036] By adopting the above technical solution, the setting of the gas spring can slow down the speed of opening or closing the hatch, thereby reducing the impact force between the hatch and the hatch and the cabin assembly, so that a good seal is maintained between the hatch and the cabin assembly.

[0037] In summary, the present application includes at least one of the following beneficial technical effects:

[0038] 1. By setting up multiple groups of mobile devices to install each group of functional units, when a functional unit fails, the corresponding locking mechanism can be unlocked, and the mobile platform can be easily pulled to the outside of the cabin assembly, so that the maintenance of the functional unit can be completed quickly, the overall maintenance cycle is short, and the growth of bacteria in the medical room can be greatly reduced;

By setting a positioning and holding mechanism, the connection stability of the mobile platform after being locked can be improved when the mobile platform is locked to the limiting component; and when the maintenance personnel push the mobile platform back into the cabin assembly, the maintenance personnel can free their hands and operate the locking mechanism to lock and position the mobile platform;

[0040] 3. By setting up a linkage mechanism, when the mobile platform is pulled outward to inspect the fan unit, the fan component can stay on the edge of the mobile platform away from the stop seat, so that the maintenance personnel can inspect the fan component; after the maintenance work is completed, the mobile platform is pushed back into the cabin assembly, and the linkage component can be used to make the fan component automatically fit into the vent to facilitate normal air supply of the fan component.

[0067] Reference Figure 4Two slide rails 17 are fixed to the inner bottom wall of the cabin assembly 1. The extension direction of the slide rails 17 is perpendicular to the extension direction of the cabin assembly 1. The two slide rails 17 are arranged at intervals and side by side. The moving device 6 includes a moving platform 61, a limiting component 62, a locking mechanism 63 and a positioning and holding mechanism 64; wherein the moving platform 61 includes a base plate 611 and two side panels 612, the two side panels 612 are respectively integrally formed at the side edges of the two opposite sides of the bottom of the base plate 611, and the extension direction of each side panel 612 is the same as the extension direction of the slide rail 17; at least two sliders are fixed to the bottom of the base plate 611, and the moving platform 61 can be moved along the slide rail 17 by installing each slider on the two slide rails 17 respectively.

[0068] Also refer to Figure 5 There are two limit components 62, and each limit component 62 is located between the slide rail 17 and the side plate portion 612; the limit component 62 includes an integrally formed base 621 and a stop seat 622, wherein the base 621 is fixed to the inner bottom wall of the cabin assembly 1, and the top surface of the base 621 is always lower than the bottom surface of the mobile platform 61; the stop seat 622 is located at a side edge of the base 621 away from the cabin door 15, and the top surface of the stop seat 622 is higher than the top surface of the mobile platform 61, so that the mobile platform 61 can be abutted and limited after the mobile platform 61 is pushed into the cabin assembly 1.

[0069] The positioning and holding mechanism 64 is disposed between the mobile platform 61 and the limiting component 62, and is used to play a role in preliminary positioning when the mobile platform 61 is pushed into the cabin assembly 1.

[0076] Reference Figure 8The locking mechanism 63 is provided on the side plate 612 of the mobile platform 61, and is used to force the positioning member 65 to be inserted into the positioning groove 623, so as to realize the locking and limiting of the mobile platform 61. Specifically, the locking mechanism 63 includes a movable arm plate 631 and a fixed column 634, wherein the fixed column 634 is fixed to a side of the side plate 612 away from the base 621, and the fixed column 634 is located at a side edge of the side plate 612 away from the blocking seat 622; one end of the movable arm plate 631 is rotatably connected to the mobile platform 61, and the other end of the movable arm plate 631 extends to the outer side of the side plate 612 away from the blocking seat 622, so that the maintenance personnel can operate the movable arm plate 631 to rotate it.

When the maintenance personnel operate the movable arm plate 631 to rotate to a horizontal position, the fixed column 634 can be inserted into the inner side of the hook portion 632, and the two are interference fit, so that the fixed column 634 and the hook portion 632 are hooked and positioned; in addition, an integrally formed abutment portion 633 is also provided on the side of the movable arm plate 631, and a convex bump is integrally formed on the side of the abutment portion 633 close to the side plate portion 612.

[0078] Reference Figure 7 , Figure 8 When the maintenance personnel force the movable arm plate 631 to rotate, the convex bump of the abutment portion 633 can gradually abut against the positioning member 65, thereby forcing the positioning member 65 to move inward; when the hook portion 632 of the movable arm plate 631 is hooked and positioned with the fixed column 634, the abutment portion 633 can force the positioning member 65 to be partially inserted into the positioning groove 623, thereby realizing the position locking of the movable platform 61, so that the air-conditioning unit is in a locked state.

[0079] Back to Figure 4 The fan unit 2 includes a sliding seat 21 and a fan component 22. Fig. 9 Two guide columns 23 are fixedly mounted on the top of the mobile platform 61. The two guide columns 23 are arranged side by side and spaced from each other, and the axial direction of the guide columns 23 is perpendicular to the moving direction of the mobile platform 61. The two guide columns 23 are slidably connected with a sliding rod 24. Specifically, both ends of the sliding rod 24 are integrally formed with a pipe sleeve 241. The inner diameter of the pipe sleeve 241 is equal to the outer diameter of the guide column 23. By respectively sleeveing ​​the two pipe sleeves 241 on the two guide columns 23, the sliding rod 24 can slide on the guide column 23.

[0080] The fan component 22 is fixed to the top of the sliding seat 21; a through sliding hole is opened on the side of the sliding seat 21, and the inner diameter of the sliding hole is equal to the outer diameter of the sliding rod 24. By matching the sliding rod 24 and penetrating it in the sliding hole, the sliding seat 21 can be slidably connected to the sliding rod 24, and the sliding seat 21 can slide along the axis direction of the sliding rod 24. A linkage mechanism 7 is provided between the sliding seat 21 and the cabin assembly 1, so that after the mobile platform 61 is pushed into the cabin assembly 1 and locked on the limiting component 62, the fan component 22 automatically abuts against the vent 141.

[0081] Specifically, refer to Fig. 9 , Fig.10 The linkage mechanism 7 includes a rotating member 71, a movable plug rod 72, a second spring 73 and a transmission assembly. The bottom of the rotating member 71 is fixedly connected with a rotating shaft 711, which is vertically penetrated by the moving platform 61 and is rotatably connected to the moving platform 61; the transmission assembly includes a rack plate 74 and a transmission gear 75, the transmission gear 75 is fixedly connected to the bottom end of the rotating shaft 711, and the transmission gear 75 is located below the moving platform 61; the rack plate 74 is fixed to the inner bottom wall of the cabin assembly 1, and the rack plate 74 is located on the outside of the transmission gear 75 along the moving direction of the moving platform 61. When the moving platform 61 is pushed into the interior of the cabin assembly 1, the transmission gear 75 can mesh with the rack plate 74 for transmission, thereby forcing the rotating member 71 to rotate automatically.

[0082] A plug hole 712 is provided on the side of the rotating member 71. The inner diameter of the plug hole 712 is equal to the outer diameter of the movable plug rod 72, so that the movable plug rod 72 can be plugged into the plug hole 712, and the movable plug rod 72 always moves axially in the plug hole 712; a connecting block 721 is fixed to one end of the movable plug rod 72, and the connecting block 721 is rotatably connected to the bottom of the sliding seat 21. The second spring 73 is sleeved on the movable plug rod 72, one end of the second spring 73 abuts against the rotating member 71, and the other end abuts against the connecting block 721; the second spring 73 is in a normal compression state, and can always generate an elastic force acting on the connecting block 721, thereby forcing the connecting block 721 to move in a direction away from the rotating member 71.

[0083] It is understandable that in the locked state, the fan component 22 abuts against the vent 141, the connecting block 721 is located at one end of the sliding rod 24 close to the abutment seat, and the sliding rod 24 stays at one end of the guide column 23 close to the baffle 14. When a fault occurs and the mobile platform 61 needs to be moved to the outside of the cabin assembly 1, the rotating member 71 rotates naturally through the meshing transmission of the transmission gear 75 and the rack plate 74, and the sliding seat 21 can always abut against the end of the sliding rod 24 under the elastic force of the second spring 73, and move together with the sliding rod 24 in the direction away from the baffle 14; after the sliding rod 24 moves to the limit position and no longer moves, the rotating member 71 continues to rotate, so that the sliding seat 21 moves in the direction away from the abutment seat 622, and then the fan component 22 automatically moves to the side edge away from the mobile platform 61 away from the abutment seat 622, so as to facilitate inspection and maintenance. At this time, the air conditioning unit is in the inspection state.

[0084] Similarly, after the inspection is completed, the mobile platform 61 is pushed into the cabin assembly 1, and the sliding seat 21 can move along the opposite path, eventually allowing the fan component 22 to re-attach to the vent 141, facilitating the normal operation of the fan component 22, and delivering the mixed air in the mixing chamber 142 to the functional chamber 143.

[0085] The implementation principle of the medical building purification and sterilization system in the embodiment of the present application is:

[0086] When the medical building purification and sterilization system is in use, if a functional component inside the cabin shell fails, the cabin door 15 is opened, and the hook portion 632 of the movable arm plate 631 is disengaged from the fixed column 634 by pushing the movable arm plate 631 upwards, so that each positioning member 65 can be quickly disengaged from the positioning groove 623, and the lock on the mobile platform 61 is released; the maintenance personnel pull the mobile platform 61 to the outside of the cabin assembly 1, and can easily perform maintenance on the corresponding functional unit, and can quickly reposition the mobile platform 61 after the maintenance is completed. The overall maintenance cycle is short, which can reduce the rapid growth of bacteria in the medical room and reduce the possibility of bacterial infection among personnel.

[0087] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
