Description

Technical Field

[0001] This utility model relates to the technical field of thermal insulation and ventilation devices, specifically to a thermal insulation and ventilation device for a low-carbon building roof. Background Technology

[0002] With people's increasing awareness of health and environmental protection, building insulation and ventilation have become important issues. The main purpose of insulation is to reduce energy flow and avoid energy loss, thereby saving energy consumption. Ventilation is the flow of air achieved through natural or artificial means, with the purpose of exchanging and circulating indoor and outdoor air. In modern life, people spend more than 80% of their time indoors. Poor indoor ventilation makes it difficult for various pollutants to be diluted and dispersed. If people are in such an environment for a long time, the harm to their health is self-evident.

[0003] Currently, most indoor ventilation systems use fans or motors to drive indoor air out, which consumes a lot of energy and does not meet the requirements of energy conservation and environmental protection. While using non-powered ventilators can achieve zero electricity cost, when the wind is too strong, a large amount of cold air from the outside will enter the room. In cold winter, this will cause the indoor temperature to drop sharply and affect indoor activities.

[0004] Therefore, it is necessary to invent a low-carbon building roof insulation and ventilation device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a thermal insulation and ventilation device for low-carbon building roofs. By using an insulated shell and air intake blocks, it solves the problem in existing technologies where a large amount of cold air from the outside enters the room when the wind is too strong, which is a problem in cold winters.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a thermal insulation and ventilation device for a low-carbon building roof, comprising an insulation shell, an air inlet block fixedly connected to the top of the insulation shell, an air exchange cylinder fixedly connected to the outer side of the air inlet block, a rotating shaft rotatably connected to the top of the air exchange cylinder, two sets of rotating seats fixedly connected to the outer side of the rotating shaft, a rotating plate hinged to the inner side of the rotating seat, a protective groove provided on the inner side wall of the rotating plate, a telescopic rod provided on the inner side of the protective groove, the top of the telescopic rod being fixedly connected to the inner side wall of the protective groove, a spring sleeved on the outer side wall of the telescopic rod, and a friction head fixedly connected to the end of the telescopic rod away from the rotating seat. The centrifugal force of the rotating shaft rotating rapidly drives the friction head to unfold and rotate, thereby rubbing against the inner side wall of the air exchange cylinder to hinder the rotation of the rotating shaft.

[0007] Preferably, an installation ring is fixedly connected to the inner wall of the air exchange cylinder, and a number of friction plates are fixedly connected to the inner wall of the installation ring, thereby reducing the wear of the friction head through the installation ring and the friction plates.

[0008] Preferably, the air inlet of the air inlet block is equipped with a filter screen, and the top of the air exchange cylinder is provided with an air outlet groove. Air exchange is completed through the air inlet block and the air outlet groove, and dust is blocked by the filter screen.

[0009] Preferably, a wind-attracting cup is fixedly connected to the top end of the rotating shaft, and an air-exchange fan blade is fixedly connected to the bottom end of the rotating shaft. The wind-attracting cup drives the rotating shaft to rotate, causing the air-exchange fan blade to rotate accordingly to achieve ventilation.

[0010] Preferably, a cleaning rod is fixedly connected to the inner wall of the ventilation cylinder, and a number of sponge blocks are fixedly connected to the top of the cleaning rod, so that the bottom of the ventilation fan blades can be cleaned by the sponge blocks on the surface of the cleaning rod.

[0011] Preferably, an insulation board is fixedly connected to the top wall of the insulation shell, and several sets of snap-fit ​​blocks are fixedly connected to the bottom end of the insulation board, so that insulation is achieved through the insulation board.

[0012] Preferably, a fireproof board is fixedly connected to the inner wall of the thermal insulation shell, and the fireproof board has several sets of snap-fit ​​grooves. The thermal insulation board and the fireproof board are snap-fitted to each other. A sound insulation layer is fixedly connected to the bottom end of the fireproof board. The sound insulation layer is fixedly connected to the bottom wall of the thermal insulation shell. Fireproofing is achieved through the fireproof board, and sound insulation is achieved through the sound insulation layer.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] By combining the heat-insulating shell with the air intake block, and using a centrifugal rotating plate, friction head, and spring, the friction resistance is automatically increased when the wind force is too strong, reducing the speed of the ventilation fan blades and preventing excessive cold air from entering in winter, thus achieving self-regulation of air volume. The ventilation fan blades are driven by the wind cup, achieving natural ventilation without electricity. The friction plate and the mounting ring work together to reduce wear on the friction head and extend the life of the braking mechanism. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figure 1-5 The illustrated low-carbon building roof insulation and ventilation device includes an insulation shell 1. An air inlet block 2 is fixedly connected to the top of the insulation shell 1. An air exchange cylinder 4 is fixedly connected to the outer side of the air inlet block 2. A rotating shaft 5 is rotatably connected to the top of the air exchange cylinder 4. Two sets of rotating seats 13 are fixedly connected to the outer side of the rotating shaft 5. A rotating plate 11 is hinged to the inner side of the rotating seat 13. A protective groove 15 is formed on the inner wall of the rotating plate 11. A telescopic rod 12 is provided inside the protective groove 15, and the top of the telescopic rod 12 is fixedly connected to the inner wall of the protective groove 15. A spring 14 is sleeved on the outer wall of the telescopic rod 12. A friction head 16 is fixedly connected to the end of the telescopic rod 12 away from the rotating seat 13. When the rotating shaft 5 rotates rapidly... Centrifugal force drives the friction head 16 to unfold and rotate, thereby rubbing against the inner wall of the air exchange cylinder 4 to hinder the rotation of the rotating shaft 5. An installation ring 9 is fixedly connected to the inner wall of the air exchange cylinder 4, and several sets of friction plates 20 are fixedly connected to the inner wall of the installation ring 9. The friction plates 20 reduce the wear of the friction head 16 through the installation ring 9. A filter screen 3 is installed at the air inlet of the air inlet block 2. An air outlet groove 7 is opened at the top of the air exchange cylinder 4. Air exchange is completed through the air inlet block 2 and the air outlet groove 7, and dust is blocked by the filter screen 3. A wind cup 6 is fixedly connected to the top of the rotating shaft 5, and an air exchange fan blade 8 is fixedly connected to the bottom of the rotating shaft 5. The wind cup 6 drives the rotating shaft 5 to rotate, so that the air exchange fan blade 8 rotates accordingly to achieve ventilation.

[0025] Refer to the instruction manual appendix Figure 1-5 A cleaning rod 10 is fixedly connected to the inner wall of the ventilation cylinder 4. Several sets of sponge blocks are fixedly connected to the top of the cleaning rod 10. The bottom of the ventilation fan blade 8 is cleaned by the sponge blocks on the surface of the cleaning rod 10. An insulation board 17 is fixedly connected to the top wall of the insulation shell 1. Several sets of snap-fit ​​blocks are fixedly connected to the bottom of the insulation board 17. Insulation is achieved by the insulation board 17. A fireproof board 18 is fixedly connected to the inner wall of the insulation shell 1. The fireproof board 18 has several sets of snap-fit ​​grooves. The insulation board 17 and the fireproof board 18 snap-fit ​​each other. A sound insulation layer 1 is fixedly connected to the bottom of the fireproof board 18. 9. The sound insulation layer 19 is fixedly connected to the bottom wall of the heat insulation shell 1. Fireproofing is achieved through the fireproof board 18, and sound insulation is achieved through the sound insulation layer 19. Through the cooperation of the heat insulation shell 1 and the air intake block 2, the centrifugal force rotating plate 11, friction head 16, and spring 14 are used to automatically increase the friction resistance when the wind force is too strong, reduce the speed of the ventilation fan blade 8, and prevent excessive cold air from entering in winter, so as to achieve self-regulation of air volume. The ventilation fan blade 8 is driven by the wind cup 6, and natural ventilation can be achieved without electricity. The friction plate 20 cooperates with the mounting ring 9 to reduce the wear of the friction head 16 and extend the life of the braking mechanism.

[0026] The working principle of this practical application is as follows:

[0027] Refer to the instruction manual appendix Figure 1-5 When ventilation is needed, the external wind pushes the wind-attracting cup 6 to rotate, which in turn drives the rotating shaft 5 and the ventilation fan blades 8 at the bottom to rotate, forming an airflow that enters from the air intake block 2, passes through the ventilation cylinder 4, and is discharged from the air outlet slot 7, achieving natural ventilation. When the wind force is small, the rotating shaft 5 rotates at a low speed, the spring 14 of the rotating plate 11 remains contracted, and the friction head 16 does not contact the inner wall of the ventilation cylinder 4, ensuring smooth ventilation. When the wind force is too strong, the rotating shaft 5 rotates at high speed, and the centrifugal force causes the rotating plate 11 to expand outward. The friction head 16 presses against the friction plate 20, reducing the rotation speed through frictional resistance and reducing the amount of cold air entering. When the ventilation fan blades 8 rotate, their bottom ends periodically contact the sponge block of the cleaning rod 10, automatically removing accumulated dust.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
