Description

Technical Field

[0001] The present invention relates to the technical field of curtain walls, and in particular to a curtain wall unit and a curtain wall system having the curtain wall unit. Background Art

[0002] Curtain wall is a non-load-bearing structure of the exterior wall of a building. It is composed of curtain wall panels and a support system installed on the building. It not only protects the building from the influence of the external environment, but also has a decorative effect and can express the aesthetic characteristics of the building.

[0003] At present, when installing curtain walls, multiple positions need to be fixed so that they can be securely installed on the keel frame. However, in order to ensure stability, these fixed positions are relatively scattered, which is not conducive to the operation of one constructor. Therefore, during installation, it is often necessary to pre-position one position, and then adjust the tightness of the remaining positions one by one, and finally, tighten all the fixed positions uniformly to complete the installation. Therefore, the installation and construction process of existing curtain walls is very cumbersome, affecting the construction efficiency.

[0004] Secondly, as a facility structure outside the building, the curtain wall can absorb heat due to direct sunlight, thus greatly affecting the temperature inside the building, especially in summer. Even with air conditioning, the area near the wall indoors can still feel the heat from the outside, thus greatly affecting the indoor temperature environment. However, there is currently no effective means to dissipate heat from the curtain wall.

[0015] Preferably, the diverter block is provided with an inclined drainage surface.

[0016] The present invention has at least the following beneficial effects: 1. An interaction cavity is arranged in the curtain wall panel of the curtain wall unit of the present invention. After the curtain wall panel is installed on the keel frame, air can be supplied to the interaction cavity by means of an air intake cavity arranged in a driving body on the keel frame, and the curtain wall panel is cooled by the air flow, thereby preventing the curtain wall exposed to the sun from affecting the indoor temperature environment.

[0017] 2. The curtain wall unit of the present invention is provided with a limiting area, and the positioning structure on the keel frame of the present invention can play a role in positioning the curtain wall panel when installing the curtain wall panel. At the same time, after positioning the curtain wall panel, the constructor controls the driving shaft on the extrusion body and makes the limiting body and the driving body cooperate, so as to simultaneously control various positioning cams to support the curtain wall panel, thereby completing the fixing of the curtain wall panel. Therefore, during installation, the present invention only needs to operate the driving shaft to fix multiple positions of the curtain wall panel, thereby improving the convenience of construction.

[0018] 3. After the curtain wall panel is installed, the driving shaft of the present invention is controlled by the elastic body and the limiting body is separated from the driving body, thereby preventing the positioning cam from being arbitrarily controlled and ensuring the stability of the curtain wall panel installation; at the same time, the present invention uses an air source (such as a fan, an air pump, a blower and an air supply system of an air conditioning system, etc.) to supply air to the air inlet cavity. When supplying air, the gas is filled into the elastomer to expand the elastomer and ensure that the driving plate on the driving shaft is separated from the limiting body, thereby stabilizing the position of the positioning cam and further ensuring the stability of the curtain wall panel installation.

[0019] 4. When the elastic body is inflated, when the air pressure in the elastic body rises, the one-way valve of the air outlet cavity is opened, and the limit pipe sends the gas into the interactive cavity of the curtain wall panel to dissipate heat for the curtain wall panel. In addition, in order to avoid the accumulation of impurities in the curtain wall panel due to long-term use and affect the weight of the curtain wall panel, the present invention sets a filter in the elastic cavity, and the filter can be used to filter the gas entering the interactive cavity to reduce the entry of impurities such as dust into the interactive cavity.

[0020] 5. The present invention further provides a cleaning structure, through which the filter screen can be automatically cleaned to ensure the filtering effect of the filter screen; 5.1 During cleaning, the present invention uses an electromagnet to control the filter to enter the cleaning chamber (and open the cavity opening of the cleaning chamber). At the same time, the hourglass body is moved to the position corresponding to the installation area, and the control rod is used to make each blade leave the sliding cavity and approach the hourglass body. At this time, the movable shaft is driven by the electromagnet to move away from the electromagnet and the end is inserted from the first air inlet to limit the curtain wall panel and ensure the stability of the curtain wall panel. When air is supplied to the elastic chamber through the air inlet chamber, the gas passes through the blades on the outer periphery of the hourglass body and drives the cleaning body to rotate, and cleans the filter in the cleaning chamber. Then the gas enters the elastic chamber and enters through the cavity opening of the cleaning chamber, and the dust and impurities after brushing are discharged from the dust exhaust chamber on the limiting cylinder, completing the self-cleaning of the filter.

[0021] 6. When the present invention supplies air to the interactive cavity, the diverter block enters the interactive cavity from the first air inlet. The diverter surface of the diverter block can be used to allow the incoming gas to be supplied to the interactive cavity at multiple angles to ensure heat dissipation of the curtain wall panel.

[0022] In addition, other advantages of the present invention will be shown in the embodiment of the present invention, thereby making the beneficial effects of the present invention more significant. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] In this embodiment, an air intake pipe is installed at one end of the driving shaft 46 , and an exhaust pipe is provided on the limiting cylinder 63 .

[0041] refer to Figure 8-Figure 15 The use principle of the driving structure of the present invention is as follows: 1. Installation of curtain wall unit: Align the positioning cavity on the curtain wall unit with the limiting body, and insert the curtain wall unit on the driving body. The limiting tube on the driving body is inserted from the axial limiting groove and moves to the position of the annular limiting groove. Then, the constructor uses the tool to cooperate with the hexagonal countersunk hole, and controls the movement of the driving shaft through the extrusion body. The limiting body in the second cavity is moved by the driving sheet until the limiting rib on the circumferential side wall of the limiting body enters the wall groove of the second cavity, so that the limiting body and the driving body are matched. Then, the driving shaft is rotated to control the driving body. Rotate and drive the driving gear to rotate, thereby controlling the positioning cam to support the curtain wall unit. At the same time, the driving body rotates, so that the limiting tube enters the annular limiting groove until the output end of the limiting tube is against the first air inlet of the annular limiting groove (wherein the diverter block is partially stuck in the first air inlet), and then the extrusion body is released, the extrusion body is reset by the elastic body, and the limiting body is reset by the first limiting spring, and finally the installation of the curtain wall unit is completed; after the installation is completed, the decorative cover is installed to hide the limiting body in the positioning cavity and play the role of decorating the curtain wall.

[0042] 2. Heat dissipation of the curtain wall unit: In the heat dissipation mode, the electromagnet is powered off, and the air source (such as a fan) supplies air to the air inlet cavity through the air inlet pipe. The gas enters the elastic cavity from the air inlet cavity. Since the sealing block of the clean cavity closes the cavity opening of the clean cavity, the air pressure in the elastic cavity rises and expands the elastic body, and at the same time, the one-way valve of the air cavity is opened. The gas in the elastic cavity enters the air outlet cavity, and the gas enters the limit tube from the movable port, and finally enters the curtain wall unit to dissipate heat for the curtain wall unit.

[0043] 2.1 During heat dissipation, the drainage surface of the diverter block can disperse the airflow discharged from the limiting tube, so that the gas can be dispersed in the interactive cavity, thereby improving the heat dissipation effect.

[0044] 2.2 During heat dissipation, in order to prevent impurities from entering the interaction cavity, a filter is provided in the elastic cavity in this embodiment, and the impurities can be filtered through the filter.

[0045] 3. Self-cleaning of the filter: In order to ensure the filtering effect of the airflow, the filter needs to be cleaned, and the present embodiment is provided with an automatic cleaning mode, which can automatically clean the filter. During cleaning, the electromagnet is energized, and the movable shaft is driven away from the electromagnet, and the sealing and diverting block and the movable shaft enter from the first air inlet, and stabilize the curtain wall unit; at the same time, the extrusion body is attracted to the electromagnet, and the filter enters the cleaning cavity, and synchronously, the driving shaft also descends, and the hourglass body moves to a position flush with the cleaning body, and the control rod in the cleaning body is also controlled to move, and the blades are driven to leave the sliding cavity and approach the hourglass body; In the above state, when air is supplied to the air inlet cavity through the air inlet pipe, the airflow first enters the air inlet cavity of the second shaft body and is discharged from one of the air outlets of the hourglass body. When the airflow blows towards the blades, the cleaning body is driven to rotate by the blades, and enters the air inlet cavity of the first shaft body after the airflow moves to the other air outlet of the hourglass body, and enters the elastic cavity from the second air inlet. Since the cavity opening of the cleaning cavity is opened by the sealing block, the gas in the elastic cavity no longer enters the limiting tube through the one-way valve, but enters the self-cleaning cavity and moves along the inner wall of the filter. When the cleaning body rotates, the brush on the outer wall of the cleaning body is used to brush the inner wall of the filter, and the impurities are discharged from the dust exhaust cavity and the exhaust pipe through the airflow, thereby completing the cleaning of the filter.

[0046] It should be noted that: in order to ensure the smooth movement of the blades and the drive shaft, the electromagnet of this embodiment can be divided into a first electromagnet and a second electromagnet. The first electromagnet is used to control the movement of the extrusion body, and the second electromagnet is used to control the movement of the control rod and the extrusion body.
