Therefore, an energy-saving ventilation device for double-layer soundproof curtain walls is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing double-layer soundproof curtain wall ventilation devices in terms of ventilation volume adjustment. The operation process is relatively cumbersome, and users often need to adjust the opening degree of each ventilation opening by rotating multiple knobs and turning complex levers at different positions on the curtain wall. In addition, some ventilation openings lack filtration, which may allow some dust or impurities to be blown into the room through the ventilation openings. Therefore, this utility model proposes an energy-saving ventilation device for double-layer soundproof curtain walls.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a double-layer soundproof curtain wall energy-saving ventilation device, comprising a mounting frame, an inner curtain wall body fixedly connected to the inner wall of the mounting frame, two grooves opened on one side of the inner curtain wall body, and several ventilation holes opened on the inner walls of the two grooves, a first square groove opened on the inner wall of the mounting frame, a motor fixedly connected to the inner wall of the first square groove, a second square groove opened on the inner wall of the mounting frame, a lead screw rotatably connected inside the mounting frame, the lead screw passing through the second square groove, the lead screw being fixedly connected to the output end of the motor, a first slider threadedly connected to the arc surface of the lead screw, a third square groove opened on the inner wall of the mounting frame, a long rod fixedly connected to the inner wall of the third square groove, a second slider slidably connected to the arc surface of the long rod, an outer curtain wall body fixedly connected to the side of the first slider and the second slider close to each other, the outer curtain wall body being slidably connected to the inner wall of the mounting frame, and two long plates fixedly connected to one side of the outer curtain wall body, the long plates being slidably connected to the inner wall of the groove.

[0006] The aforementioned components achieve the following effects: by driving the lead screw to rotate via a motor, and utilizing the threaded connection between the lead screw and the first slider, as well as the sliding engagement between the long rod and the second slider, the outer curtain wall body can be smoothly moved within the mounting frame. When the outer curtain wall body moves, the long plate on one side slides within the groove, allowing the ventilation holes within the groove to be flexibly opened or closed according to actual needs. When a large amount of ventilation is not required, the ventilation holes are closed to reduce heat exchange, lower the energy consumption of air conditioning and other equipment, and achieve energy saving; when ventilation is required, the ventilation holes are opened to introduce fresh air.

[0007] Preferably, the inner wall of the groove has two slots, a filter screen is slidably connected to the inner wall of the groove, and a circular groove is provided on both sides of the filter screen. A spring is fixedly connected to the inner wall of the circular groove, and a circular rod is fixedly connected to the other end of the spring. The circular rod is slidably connected to the inner wall of the circular groove, and the size of the circular rod is adapted to the size of the slot.

[0008] The effect achieved by the above components is as follows: through the cooperation of the spring and the round rod, the round rod is inserted into the slot to fix the filter screen in the groove. During the ventilation process, it can effectively intercept dust, debris and other particles, preventing them from entering the device and indoor space through the ventilation holes, thus ensuring the cleanliness of the air entering the room.

[0009] Preferably, the upper surface of the filter screen has two arc-shaped holes that communicate with the circular groove. A connecting rod is slidably connected to the inner wall of the arc-shaped holes, and the connecting rod is fixedly connected to the arc surface of the circular rod.

[0010] The above components achieve the following effects: to facilitate users in replacing the filter screen regularly, ensuring that the filter screen maintains a good filtration effect for a long time; when the filter screen needs to be disassembled, the connecting rod can be slid in the arc-shaped hole to more easily drive the round rod to retract in the round groove, overcoming the spring force, making the disassembly operation more effortless and convenient, and improving the ease of operation when maintaining the filter screen.

[0011] Preferably, the bottom of the inner wall of the mounting frame is provided with a plurality of circular holes, and the plurality of circular holes are evenly distributed on the bottom of the inner wall of the mounting frame.

[0012] The effect achieved by the above-mentioned components is that when rainwater accidentally enters the mounting bracket, the round holes can drain the rainwater in time, preventing rainwater from accumulating in the mounting bracket.

[0013] Preferably, a plurality of ball bearings are fixedly connected to the lower surface of the outer curtain wall body, and the ball bearings are slidably connected to the bottom of the inner wall of the mounting frame.

[0014] The effects achieved by the above components are as follows: the ball bearings reduce the friction between the outer curtain wall body and the bottom of the mounting bracket, making the movement of the outer curtain wall body smoother and easier, reducing the energy consumption required for motor drive, and reducing the wear of the outer curtain wall body and the bottom of the mounting bracket.

[0015] Preferably, two screws are fixedly connected to the upper surface of the filter screen, and a baffle is threaded onto the arc surface of the screws, with the front end of the screws being arc-shaped.

[0016] The aforementioned components achieve the following effects: the baffle restricts the movement trajectory of the connecting rod, preventing it from continuously moving forward due to the influence of the spring, thus improving the convenience of the device. The curved front end facilitates the sliding of the round rod into the slot, reducing installation difficulty.

[0017] In summary, the beneficial effects of this utility model are as follows:

[0018] In this invention, a motor drives a lead screw to rotate. Utilizing the threaded connection between the lead screw and the first slider, and the sliding engagement between the long rod and the second slider, the outer curtain wall body can be smoothly moved within the mounting frame. As the outer curtain wall body moves, the long plate on one side slides within a groove. The ventilation holes within the groove can be flexibly opened or closed according to actual needs. When a large amount of ventilation is not required, the ventilation holes can be closed to reduce heat exchange, lower the energy consumption of air conditioning and other equipment, and achieve energy saving. When ventilation is required, the ventilation holes can be opened to introduce fresh air. Attached Figure Description

[0027] Reference Figures 1-7As shown, this utility model provides a technical solution: a double-layer soundproof curtain wall energy-saving ventilation device, including a mounting frame 1, an inner curtain wall body 2 fixedly connected to the inner wall of the mounting frame 1, two grooves 3 opened on one side of the inner curtain wall body 2, and several ventilation holes 4 opened on the inner wall of each of the two grooves 3, a first square groove 5 opened on the inner wall of the mounting frame 1, a motor 6 fixedly connected to the inner wall of the first square groove 5, a second square groove 7 opened on the inner wall of the mounting frame 1, a lead screw 8 rotatably connected inside the mounting frame 1, the lead screw 8 passing through the second square groove 7, the lead screw 8 being fixedly connected to the output end of the motor 6, a first slider 9 threadedly connected to the arc surface of the lead screw 8, a third square groove 10 opened on the inner wall of the mounting frame 1, a long rod 11 fixedly connected to the inner wall of the third square groove 10, and a first slider 9 slidably connected to the arc surface of the long rod 11, and a third square groove 10 opened on the inner wall of the mounting frame 1, a long rod 11 fixedly connected to the inner wall of the third square groove 10, and a third square groove 10 slidably connected to the arc surface of the long rod 11. The second slider 12, the first slider 9, and the second slider 12 are fixedly connected to the outer curtain wall body 13 on the side close to each other. The outer curtain wall body 13 is slidably connected to the inner wall of the mounting frame 1. Two long plates 14 are fixedly connected to one side of the outer curtain wall body 13. The long plates 14 are slidably connected to the inner wall of the groove 3. The screw 8 is driven to rotate by the motor 6. By utilizing the threaded connection between the screw 8 and the first slider 9, and the sliding cooperation between the long rod 11 and the second slider 12, the outer curtain wall body 13 can be smoothly moved to slide in the mounting frame 1. When the outer curtain wall body 13 moves, the long plate 14 on one side slides in the groove 3. The ventilation hole 4 in the groove 3 can be flexibly opened or closed according to actual needs. When a large amount of ventilation is not required, the ventilation hole 4 can be closed to reduce heat exchange, reduce the energy consumption of air conditioning and other equipment, and achieve energy saving.When ventilation is needed, the ventilation hole 4 is opened to introduce fresh air. Two slots 15 are provided on the inner wall of the groove 3. A filter screen 16 is slidably connected to the inner wall of the groove 3. Circular grooves 17 are provided on both sides of the filter screen 16. A spring 18 is fixedly connected to the inner wall of the circular groove 17. A circular rod 24 is fixedly connected to the other end of the spring 18. The circular rod 24 is slidably connected to the inner wall of the circular groove 17. The size of the circular rod 24 matches the size of the slot 15. Through the cooperation of the spring 18 and the circular rod 24, the circular rod 24 is inserted into the slot 15, fixing the filter screen 16 in the groove 3. During ventilation... It can effectively intercept dust, debris, and other particles, preventing them from entering the device and indoor space through the ventilation hole 4, thus ensuring the cleanliness of the indoor air. Two arc-shaped holes are formed on the upper surface of the filter screen 16, communicating with the circular groove 17. A connecting rod 19 is slidably connected to the inner wall of the arc-shaped holes, and the connecting rod 19 is fixedly connected to the arc surface of the circular rod 24. This allows users to regularly replace the filter screen 16, ensuring it maintains a good filtration effect over a long period. When the filter screen 16 needs to be disassembled, the connecting rod 19 can be slid within the arc-shaped holes, making it easier to move the circular rod 24 back within the circular groove 17. The spring 18 is compressed to overcome its elasticity, making disassembly easier and more convenient, thus improving the ease of maintenance of the filter screen 16. Several round holes 20 are evenly distributed at the bottom of the inner wall of the mounting bracket 1. When rainwater accidentally enters the mounting bracket 1, the round holes 20 can drain the rainwater promptly, preventing excessive accumulation inside the mounting bracket 1. Several ball bearings 21 are fixedly connected to the lower surface of the outer curtain wall body 13. The ball bearings 21 are slidably connected to the bottom of the inner wall of the mounting bracket 1, reducing the distance between the outer curtain wall body 13 and the bottom of the mounting bracket 1. The friction makes the movement of the outer curtain wall body 13 smoother and easier, reducing the energy consumption required for the motor 6 to drive it, and also reducing the wear on the outer curtain wall body 13 and the bottom of the mounting bracket 1. Two screws 22 are fixedly connected to the upper surface of the filter screen 16. The arc surface of the screws 22 is threaded with a baffle 23. The front end of the round rod 24 is arc-shaped. The baffle 23 restricts the movement trajectory of the connecting rod 19, preventing the connecting rod 19 from continuously moving forward due to the influence of the spring 18, thus improving the convenience of the device. The arc-shaped front end makes it easier to guide the round rod 24 into the slot 15, reducing the installation difficulty.

[0028] The working principle is as follows: After the mounting bracket 1 is installed on the building wall, the motor 6 drives the lead screw 8 to rotate. Based on the threaded connection between the lead screw 8 and the first slider 9, and the sliding engagement between the long rod 11 and the second slider 12, the outer curtain wall body 13 slides smoothly within the mounting bracket 1. When the outer curtain wall body 13 moves, the long plate 14 slides within the groove 3, allowing the ventilation holes 4 to be opened or closed as needed, achieving ventilation volume adjustment and energy saving. The filter screen 16 within the groove 3 is fixed in the slot 15 by the cooperation of the spring 18 and the round rod 24, intercepting dust and debris to ensure air cleanliness. When the filter screen 16 needs to be removed, the round rod 24 is retracted by sliding the connecting rod 19 within the arc-shaped hole, overcoming the elasticity of the spring 18 to achieve convenient removal. The round hole 20 at the bottom of the mounting bracket 1 can promptly drain incoming rainwater. The ball bearing 21 under the outer curtain wall body 13 reduces moving friction, lowering energy consumption and wear. The screw 22 of the filter screen 16, in cooperation with the baffle 23, restricts the continuous forward movement of the connecting rod 19, thus facilitating removal.
