Description

Technical Field

[0001] This application relates to the field of building environment control technology, specifically the modular integration of direct expansion fresh air machine rooms. Background Technology

[0002] Currently, with the acceleration of urbanization, high-rise buildings are appearing more and more in various corners of the city. These high-rise buildings have increasingly higher requirements for indoor air quality. Traditional decentralized air conditioning systems can no longer meet the needs of modern buildings. Therefore, centralized air handling systems are gradually becoming the mainstream choice.

[0003] However, in existing direct expansion air handling units, it has been found that during installation, multiple air handling units are usually prefabricated into standard modules, with most of the assembly work completed in the factory before being transported to the construction site for installation. However, only the entire air handling unit module can be transported, and it is not possible to select the number of unit modules to transport according to the required quantity. This makes it inconvenient to expand the air handling system, and the large size of the grouped equipment makes transportation and installation inconvenient. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a modular integration of direct expansion fresh air equipment rooms. This modularization allows multiple fresh air equipment room modules to be connected as a whole, making the expansion of the fresh air system more convenient. It also solves the problems of excessive size and inconvenient transportation and installation associated with existing technologies. This addresses the issue that existing technologies can only transport the entire fresh air equipment room module, making it impossible to select the number of modules to transport based on the required quantity. This results in inconvenient expansion of the fresh air system and inconvenient transportation and installation due to the large size of the assembled equipment.

[0005] To achieve the above objectives, this application provides the following technical solution: a modular integration of a direct expansion fresh air unit room, comprising two mounting base plates. Each mounting base plate has a connecting plate one and a connecting plate two fixedly mounted on its upper surface. Each connecting plate one has a sliding groove on its right side. Two sliding blocks are slidably connected to the inner wall of each sliding groove. A locking block is fixedly connected to the right side of each sliding block. Springs are fixedly connected to the inner top and bottom walls of each sliding groove. The other end of each spring is fixedly connected to the opposite side of the corresponding sliding block. A guide frame is fixedly connected to the right side of each connecting plate two. A locking screw is threadedly connected to the inner wall of each guide frame. A limit plate is rotatably connected to the left end of each locking screw. The inner wall of each limit plate is slidably connected to the outer surface of the corresponding guide frame. A locking block is fixedly connected to the left side of each limit plate.

[0006] The above solution allows for modular design of the fresh air unit, enabling individual room modules to be transported separately and assembled using a quick-connect structure between them. This makes the expansion of the fresh air system more convenient and solves the problem of inconvenient transportation and installation due to excessive size. Connecting plate one and connecting plate two are installed on the upper surface of the mounting base. A sliding groove is created on the right side of connecting plate one, and a sliding block is placed on the inner wall of the groove, connected by a spring to tighten the sliding block. When two room modules need to be installed, the locking block on the surface of the sliding block passes through connecting plate two. Under the action of the spring and the inclined surface of the locking block, the locking block can pass through connecting plate two. Then, rotating the corresponding locking screw allows the limiting plate to slide on the surface of the guide frame, causing the limiting plate to drive the locking block to insert between the two corresponding locking blocks, thus locking the locking blocks. This process can be repeated to connect multiple fresh air room modules into a single unit, making the expansion of the fresh air system more convenient and solving the problem of inconvenient transportation and installation due to excessive size.

[0007] Furthermore, a limiting rod is fixedly connected to the inner bottom wall of each sliding groove, and the outer surface of each limiting rod is slidably connected to the inner wall of the corresponding sliding block.

[0008] The above method involves installing the limiting rod on the inner bottom wall of the sliding groove, fixing the limiting rod, and connecting the sliding block to the corresponding limiting rod, so that the limiting rod can achieve secondary limiting of the sliding block and ensure the stability of the sliding block when it moves up and down.

[0009] Furthermore, each of the first connecting plates is fixedly connected to a positioning block arranged at equal intervals on its right side, and each of the second connecting plates is provided with a positioning groove arranged at equal intervals on its left side. The outer surface of each positioning block is adapted to the inner wall of the corresponding positioning groove.

[0010] The above solution involves installing the positioning block on the right side of the corresponding connecting plate one and creating a positioning groove on the left side of the corresponding connecting plate two. The positioning block and the positioning groove are positioned and matched, which can improve the accuracy of the connection between connecting plate one and connecting plate two and the stability of the connection.

[0011] Furthermore, each of the mounting base plates has equidistant uprights fixedly connected to its upper surface, and each mounting base plate has a back plate and a top plate above it. The ends of each connecting plate one, connecting plate two, and back plate that are close to each other are fixedly installed to the outer surface of the corresponding upright. The bottom surface of each top plate is fixedly connected to the upper surface of the corresponding upright, connecting plate one, connecting plate two, and back plate.

[0012] The above scheme involves placing the back panel and top panel above the mounting base plate, fixing the uprights to the upper surface of the mounting base plate, connecting the first connecting plate, the second connecting plate, and both sides of the back panel to the corresponding uprights to secure the first connecting plate, the second connecting plate, and the back panel, and connecting the bottom surface of the top panel to the upper surfaces of the first connecting plate, the second connecting plate, the back panel, and the uprights. By connecting the mounting base plate, uprights, the first connecting plate, the second connecting plate, the back panel, and the top panel, a separate computer room module is formed.

[0013] Furthermore, a fresh air unit body is installed on the upper surface of each of the mounting base plates, an air outlet pipe is fixedly installed at the output end of each of the fresh air unit bodies, and an air inlet pipe is fixedly installed at the input end of each of the fresh air unit bodies.

[0014] The above method involves installing the main body of the fresh air unit on the upper surface of the mounting base, connecting the outlet duct to the output end of the main body of the fresh air unit, and connecting the inlet duct to the input end of the main body of the fresh air unit, thereby realizing the air intake and exhaust transmission of the main body of the fresh air unit.

[0015] Furthermore, each of the back panels has a pre-drilled hole on its front side, and the outer surface of each air inlet pipe is fitted to the inner wall of the corresponding pre-drilled hole.

[0016] The above solution involves creating a pre-drilled hole on the front of the back panel, which allows for easy installation of the air inlet pipe by fitting it into the pre-drilled hole.

[0017] Furthermore, each of the top plates is provided with a support rod below it, and two hanging rods are fixedly installed on the inner wall of each support rod.

[0018] The above method involves placing the support rod below the top plate and connecting the hanger rod to the corresponding support rod to install the hanger rod, which is then connected using bolts.

[0019] Furthermore, a connecting piece is fixedly installed at the top of each of the aforementioned rods, and the upper surface of each connecting piece is fixedly installed to the bottom surface of the top plate.

[0020] The above method involves installing the connecting piece at the top of the corresponding hanger and connecting the connecting piece to the bottom surface of the top plate to suspend the support rod. This allows the support rod to lift the air inlet and outlet pipes, improving the stability of the duct after installation.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] The modular integration of this direct expansion fresh air unit room utilizes components such as locking blocks, springs, locking screws, and locking blocks to move individual unit room modules to their installation positions. Then, connecting plates one and two of the two unit room modules are aligned, and the locking blocks on the sliding block surface pass through connecting plate two. Under the action of the spring and the inclined surface of the locking block, the locking blocks can pass through connecting plate two. Rotating the corresponding locking screw allows the limiting plate to slide on the guide frame surface, causing the limiting plate to move the locking block between the two corresponding locking blocks, thus locking the locking blocks. This process can connect multiple fresh air unit room modules into a single unit, making the expansion of the fresh air system more convenient and solving the problem of inconvenient transportation and installation due to excessive size. A stable support structure is formed by the connection between the mounting base plate, connecting plate one, connecting plate two, uprights, back plate, and top plate, assembling individual unit room modules. The connecting plates are fixed to the top plate by the connection of support rods, hangers, and connecting pieces, enabling the hoisting of the air inlet and outlet ducts and improving the stability of the ductwork after installation.

Each mounting base plate 1 has a back plate 16 and a top plate 17 above it. The ends of each connecting plate 1 (2), connecting plate 2 (3), and back plate 16 that are close to each other are fixedly installed to the outer surface of the corresponding upright 15. The bottom surface of each top plate 17 is fixedly connected to the upper surface of the corresponding upright 15, connecting plate 1 (2), connecting plate 2 (3), and back plate 16. The back plate 16 and top plate 17 are positioned above the mounting base plate 1. Furthermore, the upright 15 is fixed to the upper surface of the mounting base plate 1, and the two sides of the connecting plate 1 2, the connecting plate 2 3, and the back plate 16 are connected to the corresponding upright 15 to fix the connecting plate 1 2, the connecting plate 2 3, and the back plate 16.

Through the connection of the mounting base plate 1, the upright 15, the connecting plate 1 2, the connecting plate 2 3, the back plate 16, and the top plate 17, a separate computer room module is formed.

[0036] Please see Figure 1 , Figure 2 and Figure 3 Each mounting base 1 has a fresh air unit body 18 mounted on its upper surface. Each fresh air unit body 18 has an air outlet duct 19 fixedly mounted at its output end and an air inlet duct 20 fixedly mounted at its input end. The fresh air unit body 18 is mounted on the upper surface of the mounting base 1 to achieve the installation of the fresh air unit body 18. The air outlet duct 19 is connected to the output end of the fresh air unit body 18, and the air inlet duct 20 is connected to the input end of the fresh air unit body 18 to achieve the air intake and exhaust transmission of the fresh air unit body 18.

[0037] Please see Figure 1 , Figure 3 and Figure 4 Each backplate 16 has a pre-drilled hole 21 on its front side. The outer surface of each air inlet pipe 20 is adapted to the inner wall of the corresponding pre-drilled hole 21 for installation. The pre-drilled hole 21 on the front side of the backplate 16 allows for easy installation of the air inlet pipe 20 by adapting it to the pre-drilled hole 21.

[0038] Please see Figure 5 Each top plate 17 is provided with a support rod 22 below it. Two hangers 23 are fixedly installed on the inner wall of each support rod 22. The support rod 22 is set below the top plate 17, and the hangers 23 are connected to the corresponding support rod 22 to realize the installation of the hangers 23. The connection is made by bolts.

[0039] Please see Figure 5Each hanger 23 has a connecting piece 24 fixedly installed at its top end. The upper surface of each connecting piece 24 is fixedly installed to the bottom surface of the top plate 17. The connecting piece 24 is installed at the top end of the corresponding hanger 23 and connected to the bottom surface of the top plate 17 to realize the hoisting of the support rod 22. This allows the support rod 22 to lift the air inlet pipe 20 and the air outlet pipe 19, improving the stability of the air duct after installation.

[0040] In this embodiment, the modular integration of the direct expansion fresh air unit room involves using components such as locking blocks 6, springs 7, locking screws 9, and locking blocks 11 to move individual unit room modules to their installation positions. Then, the connecting plates 2 and 3 of the two unit room modules are aligned, and the locking block 6 on the surface of the sliding block 5 passes through the connecting plate 3. Under the action of the spring 7 and the inclined surface of the locking block 6, the locking block 6 can pass through the connecting plate 3. Then, rotating the corresponding locking screw 9 allows the limiting plate 10 to slide on the surface of the guide frame 8, thereby causing the limiting plate 10 to drive the locking block 11 to insert between the two corresponding locking blocks 6. This locks the card block 6, and so on, allowing multiple fresh air room modules to be connected into a whole, making the expansion of the fresh air system more convenient and solving the problem of inconvenient transportation and installation due to excessive size. By setting the connection between the installation base plate 1, connecting plate one 2, connecting plate two 3, upright 15, back plate 16 and top plate 17, a stable support structure is formed, which is combined into a single room module. By setting the connection between the support rod 22, the hanging rod 23 and the connecting piece 24, the connecting piece 24 is fixed to the top plate 17, realizing the hoisting of the air inlet pipe 20 and the air outlet pipe 19, and improving the stability of the air duct after installation.

[0041] It should be noted that the main body 18 of the fresh air unit is an existing component. After assembling the main body 18, the air inlet pipe 20 and the air outlet pipe 19, it is pre-installed inside a separate machine room module composed of the mounting base plate 1, connecting plate one 2, connecting plate two 3, upright 15, back plate 16 and top plate 17.

[0042] The working principle of the above embodiments is as follows:

[0043] A stable support structure is formed by connecting the base plate 1, connecting plate 1, connecting plate 2, connecting plate 2, upright 15, back plate 16, and top plate 17, assembling them into individual machine room modules. The main body 18 of the fresh air unit, the air inlet duct 20, and the air outlet duct 19 are installed within these individual machine room modules. The connecting plate 24 is fixed to the top plate 17 via support rods 22, hanging rods 23, and connecting pieces 24. The air inlet duct 20 and air outlet duct 19 are then hoisted. An appropriate number of machine room modules are prepared based on the building's size, and multiple fresh air machine room modules are then transported to the installation location. The individual machine room modules facilitate transportation and installation. The connecting plate 2 of the two equipment room modules corresponds to the connecting plate 3. The locking block 6 on the surface of the sliding block 5 passes through the connecting plate 3. Under the action of the spring 7 and the inclined surface of the locking block 6, the locking block 6 can pass through the connecting plate 3. Then, the corresponding locking screw 9 is rotated so that the limiting plate 10 can slide on the surface of the guide frame 8. In turn, the limiting plate 10 drives the locking block 11 to insert between the two corresponding locking blocks 6, so that the locking blocks 6 are locked. In this way, multiple fresh air equipment room modules can be connected to form a whole, making the expansion of the fresh air system more convenient and solving the problem of inconvenient transportation and installation due to excessive size.
