Detailed Implementation
[0023] The following is in conjunction with the appendix Figure 1-7 The present invention will be further described in detail below:
[0024] This utility model discloses a double-layer ventilated glass curtain wall, such as... Figure 1-7 As shown, a double-layer ventilated glass curtain wall includes columns 1, beams 2, frames 3, and a curtain wall body 4. The columns 1 and beams 2 are connected to form the installation space of the curtain wall body 4. The curtain wall body 4 is installed between the columns 1 and beams 2 through the frames 3. A ventilation spray assembly 5 is installed inside the beams 2 at the top of the curtain wall body 4, which can simultaneously spray cleaning liquid on the curtain wall body 4 outside the wall and provide ventilation. A cleaning assembly 7 is installed on the outside of the frames 3 outside the wall for cleaning the curtain wall body 4 on the exterior wall surface.
[0025] like Figure 1-7As shown, the ventilation sprinkler assembly 5 includes a rack 51, a stabilizing bracket 52, a sprinkler box 53, a nozzle 54, a drive gear 55, and a sealing plate 56. External ventilation openings 531 and internal ventilation openings 561 are respectively provided on the outer and inner side walls of the crossbeam 2. Several stabilizing brackets 52 are installed at the top inside the crossbeam 2, and racks 51 are internally slidably connected between the stabilizing brackets. A sprinkler box 53 is welded to one end of the rack 51, and several nozzles 54 are installed on the outer side wall of the sprinkler box 53. A sealing plate 56 is welded to the other end of the rack 51. The length of the rack 51 is sufficient to allow the sprinkler box 53 and the sealing plate 56 to simultaneously close the external ventilation openings 531 and 561. A motor 58 is bolted to the top inside the crossbeam 2. The output end of the motor 58 is connected to a drive gear 55, which meshes with the rack 51. In this embodiment, the stabilizing brackets 52 are installed at the top inside the crossbeam 2, providing a sliding track for the rack 51, ensuring that the rack 51 can slide along a specific direction. The motor 58 performs linear motion; the rack 51, as a transmission component, converts the rotational motion of the motor 58 into linear motion; the spray box 53 stores and transports cleaning fluid, and the nozzle 54 is installed on the outer wall of the spray box 53, which sprays the cleaning fluid onto the outer surface of the curtain wall body 4 in a certain manner to achieve the purpose of cleaning; the drive gear 55 is connected to the output end of the motor 58 and meshes with the rack 51; when the motor 58 rotates, the drive gear 55 rotates accordingly, and through the meshing transmission between the gear and the rack, it drives the rack 51 to perform linear motion; the sealing plate 56 is welded to one end of the rack 51, and its function is to work in conjunction with the spray box 53 during the movement of the rack 51 to realize the control of the opening and closing of the internal and external ventilation openings; when ventilation or ventilation spray function needs to be turned on, the motor 58 starts and drives the drive gear 55 to rotate; since the drive gear 55 meshes with the rack 51, the rack 51 moves linearly along the stable support 52 under the drive of the drive gear 55. As the rack 51 moves, the spray box 53 and the sealing plate 56 also move. When the rack 51 moves to a certain position, the spray box 53 opens the external vent 531, and the sealing plate 56 opens the internal vent 561. At this time, the internal and external vents are connected to achieve the ventilation function. If cleaning is required, at the same time as the vents are opened, the built-in water pump in the device for storing and transporting cleaning fluid inside the column 1 starts to work, and delivers the cleaning fluid to the spray box 53 through the hose. Then, the nozzle 54 sprays the cleaning fluid onto the outer surface of the curtain wall body 4.
[0026] like Figure 1-7As shown, the spray box 53 is generally a right-angled trapezoidal structure; the nozzle 54 is installed on the inclined surface of the spray box 53, and the spray direction is towards the curtain wall body 4; the inside of the column 1 is equipped with a device for storing and transporting cleaning fluid, and the built-in water pump is connected to the spray box 53 through a hose; the inner wall side of the column 1 is provided with a replenishment port 8 for replenishing the cleaning fluid to the device for storing and transporting cleaning fluid; in this embodiment, the spray box 53 is generally a right-angled trapezoidal structure, and the nozzle 54 is installed on its inclined surface; this design allows the spray direction of the nozzle 54 to be accurately towards the curtain wall body 4, ensuring that the cleaning fluid can be evenly covered on the outer surface of the curtain wall body 4, improving the cleaning effect. High cleaning effect; the column 1 is equipped with a device for storing and transporting cleaning fluid, and the built-in water pump can deliver the cleaning fluid to the spray box 53 through a hose; the replenishment port 8 facilitates the replenishment of the storage device for cleaning fluid, ensuring the continuous operation of cleaning work; during cleaning operation, the built-in water pump is activated to draw the cleaning fluid from the storage device inside the column 1 and deliver it to the spray box 53 through a hose; the cleaning fluid in the spray box 53 is sprayed onto the outer surface of the curtain wall body 4 at a certain pressure and angle by the action of the nozzle 54; when the cleaning fluid in the storage device is insufficient, the cleaning fluid can be replenished to the storage device through the replenishment port 8 on the inner wall side of the column 1;
[0027] like Figure 1-7 As shown, a dust cover 57 is installed on the inner side of the outer ventilation opening 531 of the crossbeam 2; the size of the dust cover 57 allows the spray box 53 to be accommodated when the outer ventilation opening 531 is completely closed; the outer wall of the dust cover 57 is provided with through holes for the rack 51 and the hose connecting the spray box 53; a dust screen 562 is installed inside the inner ventilation opening 561; in this embodiment, the dust cover 57 installed on the inner side of the outer ventilation opening 531 of the crossbeam 2 mainly functions to prevent dust, debris, etc. from entering the interior of the crossbeam 2 and to protect the normal operation of the ventilation spray assembly 5; the size design of the dust cover 57 allows the spray box 53 to be accommodated when the outer ventilation opening 531 is completely closed. The state of the vent 531, along with the through holes on its outer wall, provides space for the rack 51 and the hose connecting the spray box 53 to move, ensuring the normal movement of the components; the dust screen 562 installed inside the inner vent 561 can further filter the air entering the crossbeam 2, preventing dust and other impurities from entering the fan 6 and ventilation channel, thus extending the service life of the equipment; during the movement of the ventilation spray assembly 5, the dust cover 57 and the dust screen 562 are in a relatively stationary state, always playing a filtering and protective role; when the rack 51 and the spray box 53 move, they can move normally through the through holes on the dust cover 57;
[0028] like Figure 1-7As shown, a fan 6 is bolted to the bottom of the interior of the crossbeam 2. The air outlet and air inlet of the fan 6 face the external ventilation opening 531 and the internal ventilation opening 561, respectively. In this embodiment, when the fan 6 is started, indoor air is drawn in through the air inlet and then discharged to the outside through the air outlet, realizing the exchange of indoor and outdoor air and achieving the purpose of ventilation. When the ventilation spray assembly 5 is activated, the fan 6 is started, and the motor 58 drives the impeller of the fan 6 to rotate, forming airflow. Indoor air enters the interior of the crossbeam 2 through the internal ventilation opening 561, and after being acted upon by the fan 6, it is discharged to the outside through the external ventilation opening 531. The fan 6 enhances the ventilation effect, enabling rapid and effective exchange of indoor and outdoor air and improving indoor air quality. At the same time, during the ventilation process, it can also remove indoor heat and moisture, regulating indoor temperature and humidity.
[0029] like Figure 1-7 As shown, a water collection tank 9 for collecting cleaning fluid is installed at the bottom of the curtain wall body 4. In this embodiment, the water collection tank 9 is installed at the bottom of the curtain wall body 4 to collect the cleaning fluid flowing down from the outer surface of the curtain wall body 4. Under the action of gravity, the cleaning fluid flows down the outer surface of the curtain wall body 4 into the water collection tank 9.
[0030] like Figure 1-7As shown, the cleaning component 7 includes a drive box 70, a rotating bracket 71, a lead screw 72, a slider 73, a scraper 74, a driven wheel 75, and a driving wheel 76. The rotating bracket 71 is bolted to the outer wall side of the frame 3. There are two rotating brackets 71, located at the top and bottom of the curtain wall body 4 respectively. The lead screw 72 is rotatably connected between the two rotating brackets 71. The slider 73 is slidably connected to the outer wall of the frame 3. The slider 73 has a threaded hole inside and is threadedly connected to the lead screw 72. The scraper 74 is installed on the outer wall of the slider 73. The scraper 74 fits tightly against the curtain wall body 4. The drive box 70, which penetrates the interior of the beam 2, is installed on the outer wall of the beam 2. The top of the lead screw 72 extends through the drive box 70 and into the interior of the drive box 70, connecting to the driven wheel 75. The driving wheel 76, which meshes with the driven wheel 75, is rotatably connected inside the drive box 70. A drive device is installed to drive the drive wheel 76 to rotate. In this embodiment, the drive device inside the drive box 70 drives the drive wheel 76 to rotate. The drive wheel 76 meshes with the driven wheel 75, transmitting power to the driven wheel 75. The driven wheel 75 is connected to the lead screw 72, driving the lead screw 72 to rotate. Since the slider 73 has a threaded hole inside and is threadedly connected to the lead screw 72, when the lead screw 72 rotates, the slider 73 will move linearly along the lead screw 72. The scraper 74 installed on the outer wall of the slider 73 is in close contact with the curtain wall body 4. As the slider 73 moves, the scraper 74 scrapes the outer surface of the curtain wall body 4, thereby removing dirt from the outer surface of the curtain wall body 4. When cleaning is required, the drive device inside the drive box 70 is activated, driving the drive wheel 76 to rotate. The drive wheel 76, through meshing with the driven wheel 75, causes the driven wheel 75 to drive the lead screw 72 to rotate. The rotation of the lead screw 72 causes the slider 73 to move up and down along the lead screw 72. The scraper 74 installed on the outer wall of the slider 73 then scrapes up and down on the outer surface of the curtain wall body 4 repeatedly until the dirt is cleaned.
[0031] The implementation principle of this utility model embodiment is as follows:
[0032] When using this utility model:
[0033] Initial state: The rack 51 of the ventilation spray assembly 5 is in the middle position, the spray box 53 and the sealing plate 56 respectively close the external ventilation opening 531 and the internal ventilation opening 561; the motor 58, fan 6 and other equipment are in standby state; the slider 73 of the cleaning assembly 7 is in the initial position, and the scraper 74 is in contact with the curtain wall body 4 but has not started to move.
[0034] Ventilation mode: The motor 58 can drive the rack 51 to move, so that the spray box 53 opens the external ventilation port 531 and the sealing plate 56 opens the internal ventilation port 561, which, together with the fan 6, can achieve a larger air circulation.
[0035] Spray cleaning mode: When the curtain wall body needs to be cleaned, the built-in water pump in the device that stores and delivers cleaning liquid inside the column 1 is first started; the water pump delivers the cleaning liquid to the spray box 53 through the hose, and the nozzle 54 sprays the cleaning liquid onto the outer surface of the curtain wall body 4 at a certain pressure and angle; at the same time, the drive device of the cleaning component 7 is started, driving the drive wheel 76 to rotate, driving the lead screw 72 and the slider 73 to move, so that the scraper 74 scrapes up and down on the outer surface of the curtain wall body 4 to remove dirt.
