Description

Technical Field

[0001] This invention relates to the field of sterilization equipment technology, and in particular to marine air conditioning sterilization equipment. Background Technology

[0002] AHU stands for Air Handling Unit. It is a common device in air conditioning systems. Its main function is to use a fan to drive indoor and outdoor air to exchange heat with the coils inside the unit, while filtering impurities in the air to control the temperature and airflow of the air, thereby maintaining indoor temperature and air quality. Air conditioning is generally installed in the internal cabins of ships due to their relatively enclosed nature.

[0003] Typically, shipboard air conditioning units (AHUs) are equipped with plate-type coarse filters at the fresh air inlet and bag filters inside the AHU, which can block large-diameter particles from entering the air conditioning system. AHUs with energy recovery devices use molecular sieve rotors that can block more than 95% of bacterial transmission, providing a certain degree of sterilization. However, neither of these methods can completely kill bacteria and viruses in the air, nor can they completely block the spread of viruses. Therefore, a shipboard air conditioning sterilization device is needed to improve the sterilization and disinfection effect of the air conditioning system. Summary of the Invention

[0004] The purpose of this invention is to provide a marine air conditioning sterilization device that overcomes the shortcomings of insufficient sterilization effect of filters.

[0005] The technical solution to achieve the above objectives is: a marine air conditioning sterilization device, including an air supply duct installed at the air conditioning output end, a filter screen connected to the outlet end of the air supply duct, four matrix-distributed angle steels connected to the inner wall of the air supply duct, a protective mechanism installed on the angle steels, the protective mechanism being used to sterilize and disinfect the inside of the air supply duct, an opening and closing mechanism provided on the outer side of the air supply duct, an opening provided on the side wall of the air supply duct, a limit mechanism provided on the side wall of the air supply duct, a cleaning mechanism installed on the air supply duct, and an auxiliary mechanism installed on the opening and closing mechanism.

[0006] Preferably, the protective mechanism includes vertical steel, horizontal steel, ultraviolet lamps, a junction box, and a switch. Vertical steel is connected to the sidewalls of every two angle steels, and horizontal steel is connected to the sidewalls of each vertical steel. Multiple through holes are formed in the sidewalls of the vertical steel, and ultraviolet lamps are inserted into these through holes. The ultraviolet lamps are electrically connected to the wires of the junction box. A switch is located at the top of the junction box, and the switch is electrically connected to the wires of the junction box. A junction box is connected to the sidewall of the air supply duct, and the junction box is electrically connected to a power source.

[0007] Preferably, the sidewalls of the vertical steel are connected to the angle steel by screw threads, and the horizontal steel is connected to the vertical steel by screw threads.

[0008] Preferably, the opening and closing mechanism includes a fixed plate, a sliding groove, a square hole, and a baffle. Two fixed plates are connected to the side wall of the air supply pipe. The two fixed plates are located at the upper end and the lower end of the opening, respectively. Sliding grooves are formed on the side walls of the fixed plates and the side walls of the opening. The sliding grooves are L-shaped and have a square hole at their top. A baffle is slidably connected to the side wall of the sliding groove. A slider is included at both the top and bottom of the baffle. The side wall of the slider is slidably connected to the sliding groove. A slider is connected to both the top and bottom of the baffle. The width of the sliding groove located at the opening is smaller than the width of the opening.

[0009] Preferably, the limiting mechanism includes a rack, a steering gear, a rotating shaft, a fixed block, a screw, a limiting block, a connecting plate, a round rod, and a pressure rod. The rotating shaft is rotatably connected to the side wall of the air supply pipe, and a steering gear is connected to one end of the rotating shaft. Two racks, staggered about the steering gear, are slidably connected to the side wall of the air supply pipe, and the racks mesh with the steering gear. A fixed block is connected to the side wall of the air supply pipe, and a screw is threadedly connected to the side wall of the fixed block. One rack is rotatably connected to one end of the screw. A limiting block is connected to the side wall of the rack, and the side wall of the limiting block is slidably connected to a square hole. A connecting plate is connected to the top of one rack, and a pressure rod is connected to the bottom of one end of the connecting plate. The pressure rod is located above the switch. A round rod is connected to the side wall of the air supply pipe, and the side wall of the round rod is slidably connected to the connecting plate.

[0010] Preferably, the cleaning mechanism includes a motor, a reciprocating lead screw, a first square plate, a guide rod, a second square plate, a connecting rod, a first half-ring, a second half-ring, and a cleaning brush. The motor is connected to the side wall of the air supply pipe, and the output end of the motor is connected to the reciprocating lead screw. The side wall of the reciprocating lead screw is movably connected to the first square plate. The guide rod is connected to the inner side wall of the air supply pipe, and the side wall of the guide rod is slidably connected to the second square plate. The side walls of the first and second square plates are connected to the connecting rod. Multiple first half-rings are connected to the side wall of the connecting rod, and the side walls of the first and second half-rings are connected to the second half-rings. Cleaning brushes are connected to the inner side walls of both the first and second half-rings.

[0011] Preferably, the first half-ring and the second half-ring are connected by screw threads, and the ultraviolet lamp is located inside the first half-ring and the second half-ring.

[0012] Preferably, the auxiliary mechanism includes a cover plate, an outer tube, and an inner rod. The end of the outer tube away from the inner rod is connected to the cover plate, and the end of the inner rod away from the outer tube is rotatably connected to the cover plate. The side wall of the inner rod is threadedly connected to the outer tube.

[0013] The beneficial effects of this invention are:

[0014] 1) Connect the ultraviolet lamp to the air conditioner via the controller so that the ultraviolet lamp starts synchronously when the air conditioner is turned on. Use angle steel to facilitate the installation of vertical and horizontal steel, thus making it easy to install the ultraviolet lamp. The ultraviolet lamp and the air conditioner start synchronously to disinfect and sterilize the airflow in the air supply duct, thereby improving the disinfection and sterilization effect of the airflow in the air supply duct.

[0015] 2) Move the stop door into the groove inside the opening so that the stop door blocks the opening. Open the limiting mechanism, first pull the stop door outward, then pull the stop door to the left so that the stop door can be moved out of the groove inside the opening and into the groove on the fixed plate, thereby opening the opening and facilitating the maintenance of the protective mechanism.

[0016] 3) Rotating the screw drives one of the racks, which in turn causes the other rack to move in the opposite direction via a steering gear. This causes the rack to move the limiting block downwards from the top of the square hole. The limiting block moves out of the square hole and into the slide groove, thus restricting the gate within the slide groove in the opening and fixing the gate. At the same time, one of the racks moves downwards, causing the connecting plate to move downwards. The connecting plate moves the pressure rod downwards, which presses the switch downwards. By reversing the operation, the gate can be released from its limiting position. Alternatively, the pressure rod can be moved upwards to prevent the switch from being pressed, allowing the switch to turn off the UV lamp through the junction box, thus ensuring that the UV lamp does not directly shine on maintenance personnel.

[0017] 4) Start the motor. The motor drives the reciprocating screw to rotate. The reciprocating screw causes the first square plate to move back and forth along the reciprocating screw. The first square plate drives the first half ring to move back and forth. The first half ring and the second half ring are connected by screw threads, which facilitates the connection between the first half ring and the second half ring. At the same time, the first half ring drives the second half ring to move back and forth. The first half ring and the second half ring drive the cleaning brush to move back and forth, so as to clean the dust on the surface of the ultraviolet lamp.

[0018] 5) When the gate is located in the opening, insert the two baffles into the grooves on the fixed plate. Adjust the distance between the two baffles by rotating the inner rod and the threaded connection between the side wall of the inner rod and the outer tube, so that the two baffles can be put into the grooves on the fixed plate to cover the grooves on the fixed plate and prevent dust from accumulating in the grooves on the fixed plate.

The ultraviolet lamp 403 and the air conditioner are turned on synchronously to disinfect and sterilize the airflow in the air supply duct 1, thereby improving the disinfection and sterilization effect of the airflow in the air supply duct 1.

[0036] Reference Appendix Figure 2-5 The opening and closing mechanism 5 includes a fixed plate 501, a sliding groove 502, a square hole 503, and a baffle 504. Two fixed plates 501 are connected to the side wall of the air supply pipe 1. The two fixed plates 501 are located at the upper end and the lower end of the opening 9, respectively. Sliding grooves 502 are provided on the side wall of the fixed plate 501 and the side wall of the opening 9. The sliding grooves 502 are L-shaped. A square hole 503 is provided at the top of the sliding grooves 502. A baffle 504 is slidably connected to the side wall of the sliding grooves 502. A slider is included at the top and bottom of the baffle 504. The side wall of the slider is slidably connected to the sliding grooves 502. A slider is connected to the top and bottom of the baffle 504. The width of the sliding groove 502 located in the opening 9 is smaller than the width of the opening 9.

[0037] Move the stop gate 504 into the slide groove 502 inside the opening 9 so that the stop gate 504 blocks the opening 9. Open the limiting mechanism 6, first pull the stop gate 504 outward, and then pull the stop gate 504 to the left so that the stop gate 504 can be moved out of the slide groove 502 inside the opening 9 and into the slide groove 502 on the fixed plate 501, thereby opening the opening 9 and facilitating the maintenance of the protective mechanism 4.

[0038] Reference Appendix Figure 3-9 The limiting mechanism 6 includes a rack 601, a steering gear 602, a rotating shaft 603, a fixed block 604, a screw 605, a limiting block 606, a connecting plate 607, a round rod 608, and a pressure rod 609. The rotating shaft 603 is rotatably connected to the side wall of the air supply pipe 1, and one end of the rotating shaft 603 is connected to the steering gear 602. Two racks 601, staggered about the steering gear 602, are slidably connected to the side wall of the air supply pipe 1. The racks 601 mesh with the steering gear 602. A fixed block 604 is connected to the side wall of the air supply pipe 1. A screw 605 is threadedly connected to the side wall of 604. One end of the screw 605 is rotatably connected to a rack 601. A limit block 606 is connected to the side wall end of the rack 601. The side wall of the limit block 606 is slidably connected to the square hole 503. A connecting plate 607 is connected to the top of one rack 601. A pressure rod 609 is connected to the bottom of one end of the connecting plate 607. The pressure rod 609 is located above the switch 405. A round rod 608 is connected to the side wall of the air supply pipe 1. The side wall of the round rod 608 is slidably connected to the connecting plate 607.

[0039] Rotating the screw 605 drives one of the racks 601, which in turn causes the other rack 601 to move in the opposite direction via the steering gear 602. The rack 601 drives the limiting block 606 to move downward from the top of the square hole 503. The limiting block 606 moves out of the square hole 503 and into the slide groove 502, thus limiting and fixing the gate 504 within the slide groove 502 in the opening 9. At the same time, one of the racks 601 drives the connecting plate 607 downward, which in turn causes the pressure rod 609 to move downward. The pressure rod 609 presses down on the switch 405. By reversing the operation, the limiting of the gate 504 can be released. At the same time, the pressure rod 609 can be moved upward to prevent the switch 405 from being pressed. This allows the switch 405 to turn off the ultraviolet lamp 403 through the junction box 404, thus ensuring that the ultraviolet lamp 403 does not directly shine on maintenance personnel.

The first half-rings 707 and the second half-rings 708 are connected by screw threads. The ultraviolet lamp 403 is located inside the first half-rings 707 and the second half-rings 708.

[0041] When the motor 701 is started, it drives the reciprocating screw 702 to rotate. The reciprocating screw 702 causes the first square plate 703 to move back and forth along the screw. The first square plate 703 drives the first half-ring 707 to move back and forth. The first half-ring 707 and the second half-ring 708 are connected by screw threads, which facilitates the connection between the first half-ring 707 and the second half-ring 708. At the same time, the first half-ring 707 drives the second half-ring 708 to move back and forth.

[0043] When the gate 504 is located inside the opening 9, the two cover plates 801 are inserted into the grooves 502 on the fixed plate 501. By rotating the inner rod 803 and the threaded connection between the side wall of the inner rod 803 and the outer tube 802, the distance between the two cover plates 801 can be adjusted, so that the two cover plates 801 can be placed into the grooves 502 on the fixed plate 501 to cover the grooves 502 on the fixed plate 501 and prevent dust from accumulating in the grooves 502 on the fixed plate 501.
