Description

Technical Field

[0001] This invention relates to the field of air conditioning control device technology, specifically a multi-project integrated data acquisition and energy-saving control device. Background Technology

[0002] HVAC systems are widely used in various public buildings and industrial sites. In order to achieve energy-saving operation and real-time monitoring of equipment, data acquisition and energy-saving control devices are required to collect and control various parameters such as temperature, humidity, air pressure, equipment power consumption, and operating status. Most existing energy-saving control devices adopt a split structure design, integrating the acquisition module, main control module, power drive module, and shielding protection structure into a single circuit board, which is installed inside the enclosure.

[0003] Existing air conditioning and ventilation systems primarily acquire data by installing sensors and other detection elements at the air outlets. This method suffers from poor accuracy, and the fixed sensor locations make disassembly and maintenance difficult. Furthermore, the circuit boards are mounted inside the enclosure using screws and rely on cooling fans for heat dissipation. However, the operating environment of air conditioning and ventilation systems tends to be hot, especially during winter heating. The air drawn in by the fans is already quite warm, making it difficult to quickly dissipate the heat from the circuit boards. This can easily lead to overheating and malfunctions in the control devices. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-project integrated data acquisition and energy-saving control device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A multi-project integrated data acquisition and energy-saving control device includes a housing and a condensate tray fixed to the housing. A surface cooler and a fan are installed above the condensate tray.

The heat-conducting component includes a base plate that is detachably connected to the lower end of the housing. A circuit board is fixedly installed on the upper surface of the base plate by a bracket. A detection module is detachably connected to the upper end of the bracket by screws. Heat-conducting plates are symmetrically and movable on both sides of the circuit board. Multiple heat-conducting pipes are fixedly installed at equal intervals on one side of the heat-conducting plate. The transmission components are located inside the housing; An adjustment assembly is located on the outside of the detection chamber. The adjustment assembly includes an air outlet pipe that is symmetrically and fixedly embedded on the outside of the detection chamber, and a valve plate is rotatably connected inside the air outlet pipe.

[0006] Furthermore, the check valve includes: A sealing ring is fixedly installed inside the collection tube; The mounting bracket is fixedly installed inside the collection tube; The piston rod is slidably inserted into the fixed frame and is movably inserted into the sealing ring; A spring is positioned between the retaining frame and the sealing ring.

[0007] Furthermore, a connecting bracket is fixedly installed between the two heat-conducting plates, and the connecting bracket is slidably connected to the base plate. Both sides of the circuit board are filled with thermally conductive silicone, and the thermally conductive silicone is movably attached to the heat-conducting plates. Multiple positioning blocks are fixedly installed on the other side of the heat-conducting plates, and the positioning blocks are movably inserted into the positioning holes pre-drilled on the surface of the thermally conductive silicone.

[0008] Furthermore, multiple heat pipes are fixedly connected to multiple tubes at both ends, with the multiple tubes at corresponding positions fixedly penetrating the base plate, and a flexible hose inserted into one end of the exhaust pipe, with the other end of the flexible hose movably connected to the multiple tube at the corresponding position.

[0009] Furthermore, the transmission components include: The rotating shaft is rotatably connected to the outside of the detection chamber; Two No. 1 gears are fixedly installed at both ends of the rotating shaft; The second toothed plate is fixedly installed at one end of the outer surface of the connecting frame.

[0010] Furthermore, an inspection port is provided on the lower surface of the condensate pan, and a cover plate is movably connected inside the inspection port. A corrugated pipe is fixedly connected to one end of the air inlet pipe, and a plug is fixedly connected to the other end of the corrugated pipe. The plug is movably inserted into the collection tube at the corresponding position, and a pin is fixedly installed inside the plug.

[0011] Preferably, a push plate is fixedly installed on the outer surface of the plug, the push plate slides through the box, and a toothed plate is fixedly installed at one end of one side surface of the push plate.

[0012] Preferably, a No. 1 motor capable of driving the rotating shaft is fixedly installed on the inner surface of the housing. One No. 1 gear is movably meshed with two No. 1 gear plates for transmission, and another No. 1 gear is movably meshed with a No. 2 gear plate for transmission.

[0013] Furthermore, a No. 2 gear is fixedly installed on the upper end of the valve plate, a transmission frame is slidably inserted into the inside of the detection chamber, and the transmission frame slides through the detection chamber. A No. 3 tooth plate is fixedly installed at both ends of the outer surface of the transmission frame.

[0014] Preferably, the No. 2 gear is movably meshed with the No. 3 gear plate at the corresponding position for transmission, and the No. 2 motor, which can drive the No. 2 gear to rotate, is fixedly installed on the outer surface of the detection chamber.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By inserting the plug into the sampling tube, the air passage between the sampling tube and the air inlet pipe is automatically opened. The plugging and unplugging action is linked to the opening and closing of the air passage. The push plate connects the two plugs into a synchronously moving whole. With the help of the No. 1 toothed plate at the end, the transmission power is connected. When one air passage is closed, the other air passage is opened, which facilitates the detection of air at different locations. It also facilitates the introduction of lower temperature air to the two heat conduction plates. The multi-pass pipe evenly distributes the single airflow to each heat conduction pipe, so that the cooling airflow flows synchronously through all pipes, which can fully remove the heat conducted by the heat conduction plates and improve the heat dissipation uniformity. The low temperature sampling airflow after detection is introduced into the heat conduction pipe. The low temperature air sample is used to assist the circuit board in heat dissipation, realizing the secondary use of the sampling airflow. There is no need to set up an additional independent heat dissipation air source. While improving heat dissipation efficiency, it simplifies the overall structure and is suitable for use scenarios with high ambient temperature, such as air-conditioned computer rooms.

[0016] 2. The No. 1 motor operates, driving the push plate to move back and forth horizontally, which in turn drives the two plugs to complete the insertion and removal of the sampling tubes, realizing the opening and closing of the sampling gas path. At the same time, it drives the heat-conducting plates on both sides to synchronously complete the contact and separation actions with the circuit board. Through the dual-gear synchronous transmission structure of the same rotating shaft, the insertion and removal actions of the sampling gas path and the contact and separation actions of the heat-conducting plates are linked and synchronized. When the gas path is open and enters the detection state, the heat-conducting plates synchronously contact the circuit board and enter the heat dissipation working state. Only one set of driving elements is needed to complete the coordinated control of the two sets of actions, reducing the number of driving components, simplifying the overall structure of the device, and improving the coordination and reliability of the actions of each mechanism.

[0017] 3. The No. 2 motor operates, driving the transmission frame to slide back and forth in the horizontal direction, driving the valve plates in the two air outlet pipes to deflect synchronously, so that the two air outlet branches open and close respectively. By controlling the deflection angle of the valve plates, the flow rate of cooling air into the heat conduction components is adjusted to adapt to the heat dissipation requirements of the circuit board under different operating loads. At the same time, the airflow speed inside the detection chamber can be adjusted to match the sampling accuracy requirements of different detection parameters, thereby improving the device's adaptability to different working conditions.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-9In this embodiment of the invention, a multi-project integrated data acquisition and energy-saving control device includes a housing 1 and a condensate tray 101 fixed to the housing 1. A surface cooler 102 and a fan 103 are arranged above the condensate tray 101. The device also includes two acquisition pipes 104, which are respectively fixedly embedded in one side surface of the volute of the surface cooler 102 and the fan 103. A detection component 2 is disposed inside the housing 1. The detection component 2 includes a detection chamber 201, which is fixedly installed inside the housing 1. Two air inlet pipes 202 penetrating the housing 1 are fixedly installed at the upper end of the detection chamber 201. A cooling fan 208 is fixedly installed inside the detection chamber 201. A one-way valve 3 is disposed inside the acquisition pipes 104. The heat-conducting component 4 is located inside the housing 1. The heat-conducting component 4 includes a base plate 401 detachably connected to the lower end of the housing 1. A circuit board 402 is fixedly mounted on the upper surface of the base plate 401 by a bracket. A detection module 403 is detachably connected to the upper end of the bracket by screws. Heat-conducting plates 404 are symmetrically and movably arranged on both sides of the circuit board 402. Multiple heat-conducting pipes 406 are fixedly and equidistantly mounted on one side surface of the heat-conducting plate 404. The transmission component 5 is located inside the housing 1. The adjustment component 6 is located outside the detection chamber 201. The adjustment component 6 includes an air outlet pipe 601 symmetrically and fixedly embedded on the outside of the detection chamber 201. A valve plate 602 is rotatably connected inside the air outlet pipe 601.

[0022] Specifically, the condensate tray 101 is used to collect the condensate generated by the operation of the surface cooler 102, preventing the condensate from dripping and corroding the internal electrical components. The two sampling pipes 104 collect the low-temperature fresh air from the surface cooler 102 side and the indoor return air from the fan 103 side, respectively, to achieve independent sampling at two points, improving the coverage and accuracy of data collection. The detection chamber 201 provides a closed and independent detection space for the detection module 403, avoiding the influence of heat and electromagnetic interference from other components in the housing 1 on the detection accuracy. The cooling fan 208 can accelerate the airflow circulation in the detection chamber 201 and shorten the gas sample detection response time. The bottom plate 401 can be pulled out as a whole from the bottom of the housing 1, which is convenient for centralized inspection and replacement of the circuit board 402 and the detection module 403. The heat conduction plate 404, together with the airflow in the heat conduction pipe 406, carries away heat. Compared with the single-sided heat dissipation structure, it increases the heat dissipation path and speeds up the heat dissipation efficiency. The adjustment component 6 is used to adjust the opening and closing of the single air outlet channel to adjust the airflow source. Example 1

[0023] like Figure 3-5As shown, in this embodiment, the one-way valve 3 includes: a sealing ring 301 fixedly installed inside the collection tube 104; a fixing bracket 302 fixedly installed inside the collection tube 104; a piston rod 303 slidably inserted into the fixing bracket 302 and movably inserted into the sealing ring 301; and a spring 304 disposed between the fixing bracket 302 and the sealing ring 301. A maintenance port 105 is provided on the lower surface of the condensate pan 101. A cover plate 106 is movably engaged inside the maintenance port 105. A bellows pipe 203 is fixedly connected to one end of the air inlet pipe 202. A plug 204 is fixedly connected to one end of the bellows pipe 203. The plug 204 is movably inserted into the collection tube 104 at the corresponding position. A pin 205 is fixedly installed inside the plug 204. A push plate 206 is fixedly installed on the outer surface of the plug 204. The push plate 206 slides through the housing 1. A toothed plate 207 is fixedly installed at one end of one side surface of the push plate 206.

[0024] In this embodiment, under normal conditions, the elastic force of the spring 304 pushes the piston rod 303 to slide along the fixed frame 302 and press against the inner ring of the sealing ring 301, keeping the sampling tube 104 in a normally closed state. This effectively prevents external dust, moisture, and impurities from entering the sampling pipeline, ensuring the cleanliness of the sampling gas path and the accuracy of the detection data. The inspection port 105 corresponds vertically to the position of the lower base plate 401. After removing the snap-fit ​​cover 106 and the base plate 401, the internal electrical components can be directly operated from the bottom of the device without disassembling the upper main structure such as the surface cooler 102 and the fan 103, greatly reducing daily maintenance and malfunctions. The maintenance operation is difficult because when the plug 204 is inserted into the collection tube 104, the ejector pin 205 pushes the piston rod 303 to compress the spring 304 and retracts, automatically opening the air passage between the collection tube 104 and the air inlet pipe 202. The insertion and removal action is linked with the opening and closing of the air passage. The push plate 206 connects the two plugs 204 into a synchronously moving whole, and the first toothed plate 207 at the end is connected to the transmission power. When one air passage is closed, the other air passage is opened, which facilitates the detection of air at different locations. It also facilitates the introduction of lower temperature air to the two heat conduction plates 404 to improve heat dissipation efficiency.

[0025] like Figure 6 and Figure 9As shown, in this embodiment, a connecting frame 405 is fixedly installed between the two heat-conducting plates 404. The connecting frame 405 is slidably connected to the base plate 401. Both sides of the circuit board 402 are filled with thermally conductive silicone 408, and the thermally conductive silicone 408 is movably attached to the heat-conducting plates 404. Multiple positioning blocks 409 are fixedly installed on the other side of the heat-conducting plate 404. The positioning blocks 409 are movably inserted into the positioning holes pre-drilled on the surface of the thermally conductive silicone 408 to avoid misalignment during the bonding process and ensure that the thermally conductive contact surfaces are completely aligned. Multiple heat-conducting pipes 406 are fixedly connected to multiple-port pipes 407 at both ends. The multiple-port pipes 407 at the corresponding positions are fixedly inserted through the base plate 401. One end of the air outlet pipe 601 is inserted with a flexible hose 607, and one end of the flexible hose 607 is movably inserted into the multiple-port pipe 407 at the corresponding position.

[0026] In practical implementation, the connecting frame 405 connects the two heat-conducting plates 404 into an integrated structure, and slides horizontally synchronously along the guide structure on the base plate 401 to achieve the bonding and separation of the heat-conducting plate 404 and the circuit board 402. Thermally conductive silicone 408 is filled between the contact surfaces of the circuit board 402 and the heat-conducting plate 404 to eliminate the air gap between them, reduce the contact thermal resistance, and significantly improve the heat conduction efficiency. The multi-channel pipe 407 evenly distributes the single airflow to each heat-conducting pipe 406, so that the cooling airflow flows synchronously through all the pipes, fully removes the heat conducted by the heat-conducting plate 404, and improves the heat dissipation uniformity. The low-temperature sampling airflow after detection is introduced into the heat-conducting pipe, and the low-temperature gas sample is used to assist the circuit board 402 in heat dissipation, realizing the secondary use of the sampling airflow. There is no need to set up an independent heat dissipation air source. While improving the heat dissipation efficiency, it simplifies the overall structure and is suitable for use scenarios with high ambient temperatures, such as air-conditioned computer rooms.

[0027] like Figure 4 As shown, in this embodiment, the transmission component 5 includes: a rotating shaft 501 rotatably connected to the outside of the detection chamber 201; two first gears 502 fixedly installed at both ends of the rotating shaft 501; and a second gear plate 503 fixedly installed at one end of the outer surface of the connecting frame 405. A first motor 504 capable of driving the rotating shaft 501 to rotate is fixedly installed on the inner surface of the housing 1. One first gear 502 is movably meshed with two first gear plates 207 for transmission, and the other first gear 502 is movably meshed with the second gear plate 503 for transmission.

[0028] In practical implementation, when the first motor 504 drives the rotating shaft 501 to rotate, the first gear 502 and the first toothed plate 207 mesh and drive the push plate 206 to move back and forth in the horizontal direction, thereby driving the two plugs 204 to complete the insertion and removal of the sampling tube 104, realizing the opening and closing of the sampling gas path. The first gear 502 at the lower end meshes with the second toothed plate 503, driving the connecting frame 405 to move back and forth in the horizontal direction, thereby driving the heat-conducting plates 404 on both sides to simultaneously complete the contact and separation actions with the circuit board 402. Through the dual-gear synchronous transmission structure of the same rotating shaft 501, the insertion and removal actions of the sampling gas path and the disengagement actions of the heat-conducting plate 404 are linked and synchronized. When the gas path is opened and enters the detection state, the heat-conducting plate 404 simultaneously presses against the circuit board 402 and enters the heat dissipation working state. Only one set of driving elements is needed to complete the coordinated control of the two sets of actions, reducing the number of driving components, simplifying the overall structure of the device, and improving the coordination and reliability of the actions of each mechanism. Example 2

[0029] Based on Example 1, in order to solve the problem that the direction and volume of air output are not easy to adjust in Example 1.

[0030] like Figure 7 As shown, in this embodiment, a second gear 603 is fixedly installed on the upper end of the valve plate 602, a transmission frame 604 is slidably inserted into the inside of the detection chamber 201, and the transmission frame 604 slides through the detection chamber 201. A third toothed plate 605 is fixedly installed at both ends of the outer surface of the transmission frame 604. The second gear 603 is movably meshed with the third toothed plate 605 at the corresponding position for transmission. A second motor 606 capable of driving the second gear 603 to rotate is fixedly installed on the outer surface of the detection chamber 201.

[0031] In specific implementation, when the No. 2 motor 606 drives the No. 2 gear 603 on one side to rotate, the transmission frame 604 is driven to slide back and forth in the horizontal direction through the meshing transmission of the No. 3 gear plate 605. The No. 3 gear plate 605 at the other end of the transmission frame 604 simultaneously drives the No. 2 gear 603 on the other side to rotate, thereby driving the valve plates 602 in the two air outlet pipes 601 to deflect synchronously, so that the two air outlet branches open and close respectively. By controlling the deflection angle of the valve plate 602, the flow rate of cooling air flowing into the heat conduction component 4 can be adjusted to adapt to the heat dissipation requirements of the circuit board 402 under different operating loads. At the same time, the airflow velocity inside the detection chamber 201 can be adjusted to match the sampling accuracy requirements of different detection parameters, thereby improving the adaptability of the device to different working conditions.
