Description

Technical Field

[0001] This utility model relates to the field of air conditioning unit technology, and in particular to a rooftop air handling unit. Background Technology

[0002] A rooftop air handling unit is an integrated air conditioning system that combines cooling, heating, air supply, and air purification functions. It is typically installed on the roof and provides centralized air handling to large spaces through ductwork.

[0003] A search revealed a rooftop air handling unit (application number: 202421100592.X) in the patent database. This technical solution uses pads and plates to form an elastic contact with the building roof, thereby suppressing resonance and reducing noise transmission.

[0004] While the aforementioned devices can effectively suppress resonance and reduce noise transmission, the air handling unit needs to be moved and replaced as a whole after the pads age and become damaged. This is relatively troublesome and labor-intensive.

[0005] Therefore, it is necessary to invent a rooftop air handling unit to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a rooftop air handling unit. When the rubber sheet is aged and damaged, the moving support frame causes the slide to move the slider within the seven-shaped groove, allowing the support frame to support the pad. Then, the moving connecting column causes the support column to detach from the base and support block. The support block and rubber sheet lose support and fall into the rectangular groove, and the insertion post loses connection with the insertion hole. A new rubber sheet is then placed on the support block, and the support block and the new rubber sheet are then raised to connect the insertion post with the insertion hole. The support column is then re-inserted, allowing the base to support the support block via the support column. Finally, the support frame is moved, causing the slider to return to the bottom of the seven-shaped groove. At this point, the replacement of the rubber sheet is complete. This allows for easy replacement of the rubber sheet after the unit is installed, without having to lift the entire unit when the rubber sheet is aged and damaged. The operation is simple and saves manpower, solving the problem of the aforementioned device, which, although effective in suppressing resonance and reducing noise transmission, requires lifting the entire air handling unit for replacement after the pad is aged and damaged, which is relatively troublesome and labor-intensive.

[0007] According to one aspect of this disclosure, a technical solution is provided as follows: a rooftop air handling unit, comprising:

[0008] The generator set includes a main body;

[0009] The replacement component includes a base, which has two sets located on opposite sides of the bottom of the main body. A rectangular groove is formed on the top of each base, and a support block is located inside the groove. A support column is movably inserted into one side of the support block, and the support column is movably inserted into the base. A connecting column is fixedly connected to the end of the support column near the center of the main body. A rubber plate is provided on the top of the support block, with its bottom surface in contact with the top surface of the support block. A pin is fixedly installed on the top of the rubber plate. Seven-shaped sliding grooves are formed on both sides of the base, and sliders are slidably connected to these grooves. A slide frame is fixedly connected to the side of the slider away from the seven-shaped sliding groove, and a support frame is fixedly connected to the top of the slide frame.

[0010] According to at least one embodiment of the roof-mounted air handling unit of the present disclosure, the bottom of the main body is provided with a connecting plate, the top of the connecting plate being in contact with the bottom surface of the main body.

[0011] According to at least one embodiment of the roof-mounted air handling unit of the present disclosure, an extension plate is fixedly installed on the side of the connecting plate near the center of the main body, and the extension plate is bolted to the main body.

[0012] According to at least one embodiment of the rooftop air handling unit of the present disclosure, a support body is fixedly installed at the bottom of the connecting plate, and a pad is fixedly installed at the bottom of the support body.

[0013] According to at least one embodiment of the roof-mounted air handling unit of the present disclosure, the top of the pad is provided with an insertion hole, which is movably connected to an insertion post.

[0014] According to at least one embodiment of the roof-mounted air handling unit of the present disclosure, the base is fixedly connected to the ground by bolts, and the horizontal height of the support block is higher than the horizontal height of the rectangular groove.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] When the rubber sheet ages and breaks, the support frame is moved to allow the slide to move the slider within the 7-shaped groove, supporting the pad. Then, the connecting column is moved to detach the support column from the base and support block. The support block and rubber sheet lose their support and fall into the rectangular groove, disconnecting the insertion post from the insertion hole. A new rubber sheet is then placed on the support block, and the support block and the new rubber sheet are raised to reconnect the insertion post with the insertion hole. The support column is then reconnected so that the base supports the support block via the support column. Finally, the support frame is moved to allow the slider to return to the bottom of the 7-shaped groove. This completes the replacement of the rubber sheet. This method allows for easy replacement of the rubber sheet after the unit is installed, without having to lift the unit, when the rubber sheet ages and breaks. The operation is simple and saves manpower. Attached Figure Description

[0032] like Figures 1-5 As shown, the rooftop air handling unit disclosed herein may include components such as unit 100 and replacement component 110.

[0033] like Figure 1-5 As shown, this disclosure includes:

[0034] Unit 100, which includes main body 101;

[0035] Replacement component 110 includes a base 111, of which two sets are provided, located on opposite sides of the bottom of the main body 101. A rectangular groove 112 is formed on the top of each base 111, and a support block 113 is provided inside the groove 112. A support column 114 is movably inserted into one side of the support block 113, and the support column 114 is movably inserted into the base 111. A connecting column 115 is fixedly connected to one end of the support column 114 near the center of the main body 101. A rubber plate 116 is provided on the top of the support block 113, with the bottom surface of the rubber plate 116 contacting the top surface of the support block 113. A column is fixedly installed on the top of the rubber plate 116. 117. The base 111 has seven-shaped grooves 118 on both sides of its surface. A slider 119 is slidably connected to the seven-shaped grooves 118. A slide frame 120 is fixedly connected to the side of the slider 119 away from the seven-shaped grooves 118. A support frame 121 is fixedly connected to the top of the slide frame 120. The base 111 has a protruding plate on the side away from the main body 101. The protruding plate is used to fix the base 111 to the ground by bolts. The base 111 is located on both sides below the bottom of the main body 101. The base 111 and the main body 101 are connected by inserting a post 117 on the rubber plate 116 and inserting it into a hole 106 on the pad 105. The support block 113 is located above the rectangular groove 112 and is connected to the base 111. The inner wall of the 11-inch plate does not contact the base. The support block 113 supports the rubber plate 116 and the components above it. Multiple sets of support columns 114 are inserted into the support block 113 and the base 111 to support the support block 113. The support column 114 can be pulled out simultaneously through the connecting column 115 on the side of the base 111 near the center of the main body 101, so that the support block 113 loses its support and falls into the rectangular groove 112. At the same time, the rubber plate 116 falls with it, so that the rubber plate 116 loses its connection with the pad 105, making it easy to replace the rubber plate 116. The slider 119 is normally located at the bottom of the seven-shaped slide groove 118. When it is necessary to replace the rubber plate 116, it can be moved to... The support frame 121 drives the connecting frame and slider 119 to move, and then the slider 119 moves to the top left side of the seven-shaped slide groove 118. At this time, the top of the support frame 121 contacts the bottom of the pad 105. The support frame 121 can support the pad 105 and the components above it. The width of the gap in the middle of the support frame 121 is greater than the width of the rubber plate 116 and the support block 113, so that the support block 113 and the rubber plate 116 can fall normally when the support frame 121 supports the pad 105. It also facilitates the replacement of the rubber plate 116. The rubber plate 116 and the insert 117 are cast as one piece, which helps to suppress resonance and reduce the transmission of noise.

[0036] Therefore, when the rubber sheet 116 ages and breaks, the support frames 121 at both ends are moved, causing the support frames 121 to move the slide 120, so that the slider 119 moves from the bottom of the seven-shaped slide groove 118 to the top left. At this time, the base 111 supports the pad 105 through the support frame 121. Then, by moving the connecting column 115, the support column 114 is disengaged from the base 111 and the support block 113. The support block 113 loses its support and falls into the rectangular groove 112. At the same time, the rubber sheet 116 loses its support and falls with it. The insertion post 117 loses its connection with the insertion hole 106. Then, a new rubber sheet is replaced. The plate 116 is placed on the support block 113, and then the support block 113 is lifted to connect the new rubber plate 116 with the insertion post 117 and the insertion hole 106. Then the support post 114 is re-inserted so that the base 111 supports the support block 113 through the support post 114. Then the support frame 121 is moved so that the slider 119 returns to the bottom of the seven-shaped slide groove 118. At this time, the replacement of the rubber plate 116 is completed. This makes it convenient to replace the rubber plate 116 without lifting the unit 100 when the rubber plate 116 is aged and damaged after the unit 100 is installed. The operation is simple and saves manpower.

[0037] like Figure 1-3 As shown in this disclosure, the bottom of the main body 101 is provided with a connecting plate 102, the top of the connecting plate 102 is in contact with the bottom surface of the main body 101, and an extension plate 103 is fixedly installed on the side of the connecting plate 102 near the center of the main body 101. The extension plate 103 is bolted to the main body 101. A support body 104 is fixedly installed at the bottom of the connecting plate 102, and a pad 105 is fixedly installed at the bottom of the support body 104. An insertion hole 106 is opened at the top of the pad 105, and the insertion hole 106 is movably inserted into the insertion post 117. The base 111 is fixedly connected to the ground by bolts. The horizontal height of the support block 113 is higher than the horizontal height of the rectangular groove 112. The main body 101 serves as the core carrier, and the bottom is provided with the connecting plate 102. The top of the connecting plate 102 is in contact with the bottom surface of the main body 101. The bottom surface of the main body 101 is in contact with the connecting plate 102 and the extension plate 103, which are used to support the main body 101. The extension plate 103 is fixed to the side of the connecting plate 102 near the center of the main body 101 and is connected to the main body 101 by bolts to strengthen the connection between the main body 101 and the connecting plate 102. A support body 104 is fixed to the bottom of the connecting plate 102. The support body 104 is a metal plate with a corrugated cross section. The bent part of the support body 104 is tangent to the connecting plate 102 and the pad 105 respectively. The two ends of the support body 104 are fixedly connected to the walls of the connecting plate 102 and the pad 105 that are close to each other. The pad 105 is installed at the bottom of the support body 104 and has an insertion hole 106 at the top for mating with the replacement component 110.

[0038] Therefore, when the main body 101 is turned on, it will generate a certain vibration. Through the deformation of the support body 104, the support body 104 can be squeezed by the connecting plate 102 and the pad 105 to generate vertical deformation. At the same time, the support body 104 can also extend in the horizontal direction. Thus, the support body 104 can change the vertical and horizontal vibration frequency of the main body 101 during operation, suppress the resonance between the main body 101 and the pad 105, and reduce the vibration noise generated by the main body 101 on the building during operation.

[0039] It should also be noted that the main body 101 is formed by a hollow shell structure. The core components within the cavity of the main body 101 include an air handling section assembly, a fan system, a cooling / heating source assembly, a control and sensing system, and auxiliary components. The air handling section assembly includes a filter, a surface cooler, a heater, and a humidifier. The fan system includes a centrifugal or axial fan and a fan motor. The cooling / heating source assembly includes a compressor, a condenser, and a heat exchanger. The control and sensing system includes a controller, sensors, and actuators. The auxiliary components include fresh air and return air valves, inspection doors and windows, and a drain pan. The main functions include air conditioning, air purification, air delivery and distribution, automatic control and energy saving, and fresh air treatment. The conditioning functions include cooling and dehumidification, heating and humidification. The compressor is electrically connected to the controller, and the compressor is connected to the heat exchanger through pipes. The fan is electrically connected to the controller. The top surface of the main body 101 is equipped with air vents. The fan draws in air and blows it to the heat exchanger. The heated or cooled air is then delivered into the building through the air vents to achieve air treatment. The specific usage and control methods are existing known technologies and will not be described in detail here.

[0040] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0041] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
