Description

Technical Field

[0001] The present invention relates to the technical field of building equipment installation, and particularly relates to a BIM-based HVAC installation structure. Background Art

[0002] An air conditioner, i.e., an air regulator, adjusts temperature and humidity. A wall-mounted air conditioner is a unit used to provide processed air temperature change for a spatial area (generally enclosed). Its function is to adjust parameters such as the temperature, humidity, cleanliness, and air velocity of the air in the room (or enclosed space, area) to meet the requirements of human comfort or technological processes. HVAC (Heating, Ventilation, and Air Conditioning) is a type of air conditioner with functions of heating, ventilation, and air conditioning. Since the main functions of HVAC include these three aspects: heating, ventilation, and air conditioning, the combined abbreviation of these three functions is HVAC. On the one hand, traditional installation methods usually require a large amount of manpower and time for installation operations, and it is difficult to ensure the installation accuracy. During the installation process, due to the lack of effective fixing and supporting structures, the HVAC is prone to shaking, displacement, etc., which not only affects its normal operation but may also pose safety hazards. On the other hand, traditional installation structures have poor adaptability to building walls and are difficult to meet the installation requirements of different building types and wall structures. At the same time, after installation, due to the lack of effective protection measures, the HVAC is easily affected by external environmental factors such as ultraviolet rays, wind, and rain, reducing its service life. Therefore, we introduce a BIM-based HVAC installation structure. Summary of the Invention

[0003] The main purpose of the present invention is to provide a BIM-based HVAC installation structure, which can effectively solve the problems in the background art.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0005] A BIM-based HVAC installation structure includes an outer wall and fixing bolts. There are four fixing bolts. Ear plates are fixedly connected to the front ends of the outer wall by threading the fixing bolts. An installation base plate is fixedly connected to the inner sides of the four ear plates. A fixing device is fixedly connected to the middle of the lower end of the installation base plate. First chutes are opened at the front and rear parts of the upper end of the installation base plate. A fixing device is fixedly connected to the middle of the upper end of the installation base plate. A sliding plate is fixedly connected to the middle of the upper end of the installation base plate. The sliding plate is located below the supporting device. Support columns are fixedly connected to the left and right parts of the upper end of the fixing device. A protective device is fixedly connected to the upper ends of the two support columns.

[0006] The fixing device includes an electric push rod. The output end of the electric push rod penetrates through the mounting base plate and is fixedly connected to a lifting plate. The left part and the right part of the front end of the lifting plate are both inserted and connected with movable components. The outer surfaces of the two movable components are both fixedly connected with clamping components. The electric push rod is fixedly connected to the middle part of the lower end of the mounting base plate.

[0007] As a further improvement of the above solution, the movable component includes a first movable plate and a second movable plate. Second movable grooves are formed in the lower part of the front end of the first movable plate and the lower part of the rear end of the second movable plate. A first movable linkage rod is movably connected in the two second movable grooves together. First movable grooves are formed in the upper part of the front end of the first movable plate and the upper part of the rear end of the second movable plate. A second movable linkage rod is movably connected in the two first movable grooves together. The upper part of the front end of the first movable plate and the upper part of the rear end of the second movable plate are fixedly connected together with a rotating rod. The rotating rod is located below the second movable linkage rod. The first movable plate and the second movable plate are both movably connected to the front and rear sides of the lifting plate.

[0008] By adopting the above technical solution: when the lifting plate moves, the movement of the first movable plate and the second movable plate is driven by the movement of the first movable linkage rod in the second movable groove, playing a role in force transmission and providing a power source for the subsequent movement of the clamping component.

[0009] As a further improvement of the above solution, the clamping component includes a slider. A second sliding groove is formed in the middle part of the lower end of the slider. The upper right part of the slider is fixedly connected with a clamping plate. A plurality of anti-slip stickers are fixedly connected to the right end of the clamping plate. The slider is slidably connected to the upper left part of the sliding plate.

[0010] By adopting the above technical solution: the clamping plate is used to directly contact the heating, ventilation and air conditioning (HVAC) for fixing. The anti-slip stickers increase the friction with the HVAC, improve the clamping stability and prevent the HVAC from slipping.

[0011] As a further improvement of the above solution, the protection device includes a left plate and a right plate. Pulling grooves are formed in the right end of the left plate and the left end of the right plate. A pulling plate is movably connected in the pulling grooves. Ultraviolet absorption pads are fixedly connected to the surfaces of the left plate, the right plate and the pulling plate. The left plate and the right plate are respectively fixedly connected to the upper ends of the support columns.

[0012] By adopting the above technical solution: the ultraviolet absorption pads can effectively absorb the ultraviolet rays in the sunlight, reduce the damage of the ultraviolet rays to the HVAC, and extend its service life.

[0013] As a further improvement of the above solution, the supporting device includes a bearing seat. Four corners at the lower end of the bearing seat are fixedly connected with support rods. A circular groove is opened in the middle of the upper end of the bearing seat. A connection groove is opened at the lower end of the bearing seat. A plurality of heat dissipation fins are fixedly connected in the connection groove. The bearing seat is directly above the installation base plate.

[0014] By adopting the above technical solution: The heat dissipation fins in the connection groove help to accelerate the heat dissipation speed of the HVAC, improve its working efficiency, and prevent the performance and service life from being affected due to overheating.

[0015] As a further improvement of the above solution, the structure of the left plate is the same as that of the right plate and they are symmetrically distributed left and right. The pull-out plate is located between the left end and the right end of the left plate and the right plate.

[0016] By adopting the above technical solution: The left and right plates that are symmetrically distributed left and right make the protection device more beautiful and stable. At the same time, it is also convenient for manufacturing and installation. The pull-out plate is located between the two, and it can flexibly adjust the protection range in the left and right directions to adapt to HVACs of different sizes.

[0017] As a further improvement of the above solution, the position and size of the second chute are adapted to the position and size of the sliding plate. A plurality of anti-slip stickers are longitudinally and equidistantly distributed one by one.

[0018] By adopting the above technical solution: The longitudinally equidistantly distributed anti-slip stickers can evenly increase the friction force and improve the stability and reliability of clamping.

[0019] As a further improvement of the above solution, the rotating rod is inserted and connected to the left part of the front end of the sliding plate. The second movable linkage rod is inserted and connected to the front end of the slider. The first movable linkage rod is inserted and connected to the left part of the front end of the lifting plate.

[0020] By adopting the above technical solution: The connection of the rotating rod on the sliding plate provides a fulcrum for the rotation of the movable plate. The connection of the second movable linkage rod and the slider transmits the movement of the movable plate to the slider. The connection of the first movable linkage rod and the lifting plate enables the movement of the lifting plate to drive the movement of the movable plate.

[0021] As a further improvement of the above solution, both the first movable plate and the second movable plate are in an L-shaped structure.

[0022] By adopting the above technical solution: The movable plate in an L-shaped structure can better realize the transmission and conversion of force.

[0023] As a further improvement of the above solution, the structures of the two movable components are the same and they are symmetrically distributed left and right. The structures of the two clamping components are the same and they are symmetrically distributed left and right.

[0024] By adopting the above technical solutions: the symmetrically distributed movable components and clamping components can make the clamping force more evenly distributed on the HVAC, improving the stability and reliability of clamping.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. In the present invention, the mounting base plate is fixed to the outer wall through four fixing bolts, with simple and efficient operation. The electric push rod in the fixing device drives the lifting plate to move, thereby driving the movable components and clamping components to act, realizing the quick clamping and fixing and disassembly of the HVAC. The anti-slip stickers on the clamping components increase the friction with the HVAC, improving the fixing stability and effectively preventing the HVAC from shaking or shifting.

[0027] 2. In the present invention, the protection device is composed of a left plate and a right plate. The ultraviolet absorption pads on the surface and the surface of the pull-out plate can effectively absorb ultraviolet rays, reducing the damage of sunlight to the HVAC and extending its service life. The pull-out plate can move in the pull-out groove and can flexibly adjust the protection range according to the sizes of different HVACs, with strong adaptability.

[0028] 3. In the present invention, the bearing seat of the support device is located directly above the mounting base plate, playing a role in stably supporting the HVAC. The circular grooves on the bearing seat better adapt to the shape of the HVAC, improving the stability. The several heat dissipation fins in the connecting groove contribute to rapid heat dissipation, improving the working efficiency of the HVAC and ensuring its operation in a good temperature environment.

The front ends of the outer wall 1 are all threadedly and fixedly connected to ear plates 5 through the fixing bolts 6. An installation bottom plate 4 is fixedly connected to the inner sides of the four ear plates 5. A fixing device 8 is fixedly connected to the middle of the lower end of the installation bottom plate 4. First chutes 7 are opened at the front and rear parts of the upper end of the installation bottom plate 4. A fixing device 8 is fixedly connected to the middle of the upper end of the installation bottom plate 4. A sliding plate 10 is fixedly connected to the middle of the upper end of the installation bottom plate 4. The sliding plate 10 is located below the support device 9. Support columns 3 are fixedly connected to the left and right parts of the upper end of the fixing device 8. A protection device 2 is fixedly connected to the upper ends of the two support columns 3.

[0043] In this embodiment, the fixing device 8 includes an electric push rod 81. The output end of the electric push rod 81 penetrates through the installation bottom plate 4 and is fixedly connected to a lifting plate 82. The left and right parts of the front end of the lifting plate 82 are both inserted and connected with movable components 83. Clamping components 84 are fixedly connected to the outer surfaces of the two movable components 83. The electric push rod 81 is fixedly connected to the middle of the lower end of the installation bottom plate 4. The movable component 83 includes a first movable plate 831 and a second movable plate 834. Second movable slots 837 are opened at the lower parts of the front end of the first movable plate 831 and the rear end of the second movable plate 834. A first movable linkage rod 832 is movably connected in the two second movable slots 837. First movable slots 836 are opened at the upper parts of the front end of the first movable plate 831 and the rear end of the second movable plate 834. A second movable linkage rod 835 is movably connected in the two first movable slots 836. The upper parts of the front end of the first movable plate 831 and the rear end of the second movable plate 834 are fixedly connected together with a rotating rod 833. The rotating rod 833 is located below the second movable linkage rod 835. The first movable plate 831 and the second movable plate 834 are both movably connected to the front and rear sides of the lifting plate 82. The clamping component 84 includes a slider 841. A second chute 842 is opened at the middle of the lower end of the slider 841. A clamping plate 843 is fixedly connected to the upper right part of the slider 841. A plurality of anti-slip stickers 844 are fixedly connected to the right end of the clamping plate 843. The slider 841 is slidably connected to the upper left part of the sliding plate 10. The position and dimension of the second chute 842 are adapted to the position and dimension of the sliding plate 10. The plurality of anti-slip stickers 844 are longitudinally and equally spaced and distributed one by one. The rotating rod 833 is inserted and connected to the upper left part of the front end of the sliding plate 10. The second movable linkage rod 835 is inserted and connected to the front end of the slider 841. The first movable linkage rod 832 is inserted and connected to the upper left part of the front end of the lifting plate 82. The first movable plate 831 and the second movable plate 834 are both in an L-shaped structure. The structures of the two movable components 83 are the same and symmetrically distributed left and right. The structures of the two clamping components 84 are the same and symmetrically distributed left and right.

[0044] Through the above solution: After the electric push rod 81 is started, its output end drives the lifting plate 82 to move up and down. When the lifting plate 82 moves, it drives the first movable linkage rod 832 to move. Since the first movable linkage rod 832 is movably connected in the second movable groove 837 at the lower part of the first movable plate 831 and the second movable plate 834, the first movable plate 831 and the second movable plate 834 rotate around the rotating rod 833. At the same time, the second movable linkage rod 835 in the first movable groove 836 at the upper part of the first movable plate 831 and the second movable plate 834 also moves accordingly. And the second movable linkage rod 835 is inserted and connected with the slider 841 in the clamping assembly 84, thereby pushing the slider 841 to slide on the sliding plate 10. The two symmetrically distributed movable assemblies 83 and clamping assemblies 84 on the left and right act synchronously, so that the clamping plates 843 move closer to or away from each other in the middle, realizing the clamping and fixing of the HVAC. Driven by the electric push rod 81, the operation is convenient and fast, and the quick fixing and disassembly of the HVAC can be realized. The anti-slip sticker 844 on the clamping assembly 84 can increase the friction with the HVAC and improve the stability of the fixing.

[0045] In this embodiment, the protection device 2 includes a left plate 21 and a right plate 23. Drawer slots 22 are opened at the right end of the left plate 21 and the left end of the right plate 23. A drawer plate 24 is movably connected in the drawer slots 22. Ultraviolet absorption pads 25 are fixedly connected to the surfaces of the left plate 21, the right plate 23, and the drawer plate 24. The left plate 21 and the right plate 23 are respectively fixedly connected to the upper ends of the support columns 3. The structure of the left plate 21 is the same as that of the right plate 23 and they are symmetrically distributed left and right. The drawer plate 24 is located between the left end and the right end of the left plate 21 and the right plate 23.

[0046] Through the above solution: The protection device 2 is composed of a left plate 21 and a right plate 23. The structures of the left plate 21 and the right plate 23 are the same and they are symmetrically distributed left and right. Ultraviolet absorption pads 25 are fixedly connected to the surfaces of the left plate 21, the right plate 23, and the drawer plate 24. The drawer plate 24 can move in the drawer slots 22 of the left plate 21 and the right plate 23, and the protection range can be adjusted according to needs. The ultraviolet absorption pads 25 can effectively absorb ultraviolet rays, reduce the damage to the HVAC, and extend its service life. The design of the drawer plate 24 can flexibly adjust the protection range to adapt to HVACs of different sizes.

[0047] In this embodiment, the support device 9 includes a bearing seat 91. Four corners at the lower end of the bearing seat 91 are respectively fixedly connected with support rods 92. A circular groove 93 is opened in the middle of the upper end of the bearing seat 91. A connection groove 94 is opened at the lower end of the bearing seat 91. A plurality of heat dissipation fins 95 are fixedly connected in the connection groove 94. The bearing seat 91 is located directly above the installation base plate 4.

[0048] Through the above solution: The bearing seat 91 of the support device 9 is located directly above the mounting base plate 4, providing support for the HVAC, and the support rods 92 at the four corners of the lower end of the bearing seat 91 ensure its stability. A number of heat dissipation fins 95 are fixedly connected in the connection groove 94, which helps with heat dissipation and improves its working efficiency.

[0049] It should be noted that the present invention is a BIM-based HVAC installation structure. First, the mounting base plate 4 with the ear plates 5 is fixed to the outer wall 1 by four fixing bolts 6. When installing the HVAC, the electric push rod 81 in the fixing device 8 is started, and the output end of the electric push rod 81 pushes the lifting plate 82 up or down. When the lifting plate 82 moves, it drives the first movable linkage rod 832 in the movable assembly 83 that is inserted and connected to it. Since the first movable linkage rod 832 is also movably connected to the second movable grooves 837 at the lower parts of the first movable plate 831 and the second movable plate 834, the first movable plate 831 and the second movable plate 834 rotate around the rotating rod 833. At the same time, the second movable linkage rod 835 in the first movable grooves 836 at the upper parts of the first movable plate 831 and the second movable plate 834 also moves accordingly. And the second movable linkage rod 835 is also inserted and connected to the slider 841 in the clamping assembly 84, thereby pushing the slider 841 to slide on the sliding plate 10. The two symmetrically distributed movable assemblies 83 and clamping assemblies 84 on the left and right act synchronously, causing the clamping plates 843 to move closer to or away from each other in the middle, realizing the clamping and fixing of the HVAC. When the HVAC is installed, the bearing seat 91 in the support device 9 located directly above the mounting base plate 4 provides support for the HVAC, and the support rods 92 at the four corners of the lower end of the bearing seat 91 ensure its stability. The circular groove 93 on the bearing seat 91 can better adapt to the shape of the HVAC. The number of heat dissipation fins 95 in the connection groove 94 helps with heat dissipation. In addition, the left plate 21 and the right plate 23 in the protection device 2, through the ultraviolet absorption pads 25 fixedly connected to their surfaces and the surface of the pull-out plate 24, play a protective role for the HVAC. The ultraviolet absorption pads 25 absorb the ultraviolet rays in the sunlight, preventing the HVAC from being damaged by long-term sunlight irradiation, thus better protecting the HVAC and extending its service life. The pull-out plate 24 can move in the pull-out grooves 22 of the left plate 21 and the right plate 23, and the protection range can be adjusted as needed. The two support columns 3 support the protection device 2.
