Description

Technical Field

[0001] This invention relates to the field of urban underground infrastructure technology, and in particular to a ventilation shaft for an urban underground integrated pipe gallery. Background Technology

[0002] Urban underground utility tunnels are public tunnels that integrate the construction of various municipal pipelines such as electricity, communication, water supply and drainage, and gas. They are important infrastructure to ensure the operation of the city. As a core supporting facility of the utility tunnel, the ventilation system directly affects the environmental quality and equipment operation safety within the tunnel. Ventilation shafts are a key component of the ventilation system, responsible for the function of exchanging air between the tunnel and the outside.

[0003] When existing ventilation shafts are in use, fans need to be installed inside to achieve exhaust and intake operations. However, some ventilation shafts, in addition to their ventilation function, also provide some auxiliary lighting through a transparent structure on top. However, the light-transmitting structure located on the ground is exposed to the outside for a long time and lacks an effective linkage structure for ventilation. This makes the light-transmitting structure easily affected by dirt, which can affect its normal use. Summary of the Invention

[0004] The purpose of this invention is to solve the problem in the prior art that the transparent structure at the top provides some auxiliary lighting, but the light-transmitting structure located on the ground is exposed to the outside for a long time and lacks an effective linkage structure for ventilation, making the light-transmitting structure easily affected by dirt and affecting its normal use. Therefore, this invention proposes a ventilation shaft for urban underground integrated pipe corridors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A ventilation shaft for an urban underground utility tunnel includes a shaft mechanism. The lower end of the shaft mechanism is connected to the ventilation utility tunnel, and the upper end of the shaft mechanism protrudes from the ground. An air exchange mechanism is installed inside the shaft mechanism for supplying air to the shaft mechanism and extracting air from the underground utility tunnel. A transmission mechanism is also installed inside the shaft mechanism. There are two transmission mechanisms, which are symmetrically arranged on the left and right sides inside the shaft mechanism and are both connected to the air exchange mechanism. A wiping mechanism is also installed on the outside of the air exchange mechanism.

[0007] Preferably, the shaft mechanism includes a light-transmitting window, a shielding top cover, a mounting base plate, a ventilation grid, and fixing bolts. There are two light-transmitting windows, which are symmetrically fixed on the left and right sides inside the shaft mechanism.

[0008] Preferably, the shielding top cover has a conical structure and is fixedly installed at the top of the well mechanism. There are two mounting base plates, which are symmetrically fixedly installed on the front and rear sides of the well mechanism. The fixing bolts pass through the vent grid and the mounting base plates and are used to fix the vent grid on the outside of the mounting base plates.

[0009] Preferably, the ventilation mechanism includes a connecting seat, a filter screen, a servo motor, ventilation fan blades, an output helical gear, a mounting base, a transmission shaft, and a transmission gear. The main body of the connecting seat is a ring structure, and the connecting seat is fixedly disposed on the inner side of the ventilation mechanism.

[0010] Preferably, there are two filter elements, which are symmetrically fixed on the upper and lower sides of the connecting base. The servo motor is fixed on the lower side of the filter element, and the top of the servo motor is provided with an output shaft, which is located inside the two filter elements.

[0011] Preferably, the ventilation fan blades are fixedly mounted on the outer wall of the top output shaft of the servo motor, and the servo motor and the ventilation fan blades together form a ventilation structure. The output helical gear is coaxially mounted on the top output shaft of the servo motor.

[0012] Preferably, there are two mounting bases, which are symmetrically fixed on the left and right sides of the top surface of the connecting base. The transmission shaft is rotatably disposed on the inner side of the two mounting bases, and the transmission gear is fixedly disposed on the outer wall of the transmission shaft. The transmission gear meshes with the output helical gear for transmission.

[0013] Preferably, the transmission mechanism includes an eccentric shaft, a first connecting rod, a connecting support plate, a second connecting rod, a connecting guide shaft, a guide frame, and an inner cleaning brush. The transmission mechanism is a turntable structure, and the transmission mechanism is fixedly installed at both ends of the transmission shaft. The eccentric shaft is fixedly installed on the outer wall of the transmission mechanism.

[0014] Preferably, the first connecting rod is rotatably disposed on the outside of the eccentric shaft, the connecting support plate is fixedly disposed on the top end of the first connecting rod, the second connecting rod is connected to the connecting support plate, the connecting guide shaft is rotatably disposed on the top end of the second connecting rod, the guide frame is fixedly disposed on the inner wall of the well mechanism, the inner cleaning brush is slidably disposed in the guide frame and fits against the inner wall of the light-transmitting window, a magnet is fixedly connected inside the inner cleaning brush, and the inner cleaning brush is connected to the connecting guide shaft.

[0015] Preferably, the wiping mechanism includes a guide slider, an outer wiping brush, and an adsorption magnet. The guide slider is symmetrically fixed on the outer wall of the wiping mechanism. The wiping mechanism is slidably disposed on the outer wall of the well mechanism via the guide slider. The outer wiping brush is fixedly disposed on the inner side of the wiping mechanism and fits against the outer wall of the light-transmitting window. The adsorption magnet is fixedly disposed inside the outer wiping brush and is adsorbed and connected to the magnet in the inner cleaning brush.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In this invention, by setting up components such as a ventilation mechanism, a transmission mechanism, and a wiping mechanism, the servo motor of the ventilation mechanism drives the ventilation fan blades to achieve the ventilation function, while simultaneously driving the output helical gear to mesh with the transmission gear. In turn, the transmission shaft drives two symmetrical transmission mechanisms to operate. The transmission mechanism drives the inner cleaning brush to slide along the guide frame through the linkage of components such as the eccentric shaft and the first connecting rod. The inner cleaning brush then links the outer wiping brush of the wiping mechanism to move synchronously through magnetic adsorption, so that the inner cleaning brush and the outer wiping brush wipe the inner and outer walls of the light-transmitting window simultaneously. This device can solve the technical problem of the existing ventilation well light-transmitting structure lacking ventilation and being easily affected by dirt when there is no effective linkage between the cleaning structure and the light effect. It realizes the synchronous operation of ventilation and cleaning without the need for an additional cleaning power source.

[0018] 2. In this invention, by setting up components such as a shaft mechanism, two symmetrical transmission mechanisms, and a wiping mechanism, the light-transmitting window of the shaft mechanism ensures auxiliary lighting, while the top cover and ventilation grid combine protection and ventilation. At the same time, by utilizing the stable linkage between the transmission mechanism and the ventilation mechanism, as well as the magnetic adsorption synergy between the inner cleaning brush and the outer wiping brush, the cleaning action has good synchronicity and stability, avoiding the problem of uneven force or incomplete cleaning of the light-transmitting window caused by unilateral cleaning. This device can significantly improve the cleaning effect and long-term stability of the light-transmitting window through the coordinated linkage of multiple components, while ensuring the basic functions of ventilation, lighting, and protection, thus taking into account both practicality and reliability.

[0019] 3. In this invention, by setting components such as the guide slider of the wiping mechanism and the magnet of the inner cleaning brush, the guide slider provides guidance and limit for the sliding of the wiping mechanism. The magnet and the adsorption block are used to achieve contactless linkage between the inner and outer cleaning components. This allows the cleaning action to be accurately synchronized without additional mechanical connection structures, which simplifies the device structure, reduces maintenance costs, and avoids the tedious operation of manual cleaning. This device can achieve automatic synchronous cleaning of the light-transmitting window through innovative linkage structure design, effectively extending the cleaning cycle and service life of the light-transmitting window and improving the overall operating efficiency of the ventilation shaft.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Example, refer to Figure 1 - Figure 8 A ventilation shaft for an urban underground integrated pipe gallery includes a shaft mechanism 1. The lower end of the shaft mechanism 1 is connected to the ventilation pipe gallery, and the upper end of the shaft mechanism 1 protrudes from the ground. An air exchange mechanism 2 is installed inside the shaft mechanism 1. The air exchange mechanism 2 is used to supply air to the inside of the shaft mechanism 1 and to extract air from the inside of the underground pipe gallery. A transmission mechanism 3 is also installed inside the shaft mechanism 1. There are two transmission mechanisms 3, which are symmetrically arranged on the left and right sides inside the shaft mechanism 1. Both transmission mechanisms 3 are connected to the air exchange mechanism 2. A wiping mechanism 4 is also installed on the outside of the air exchange mechanism 2. By adopting the above technical solution, the air exchange function of supplying air to the inside of the shaft mechanism 1 and extracting air from the underground pipe gallery is realized, and it also has a linkage cleaning capability.

[0031] Furthermore, the shaft mechanism 1 includes a light-transmitting window 101, a shielding top cover 1011, a mounting base plate 1012, a ventilation grid 1013, and a fixing bolt 1014. There are two light-transmitting windows 101, which are symmetrically fixed on the left and right sides inside the shaft mechanism 1. Through the above technical solution, auxiliary lighting conditions are provided for the underground integrated pipe gallery.

[0032] Furthermore, the shielding top cover 1011 has a conical structure and is fixedly installed at the top of the well mechanism 1. There are two mounting base plates 1012, which are symmetrically fixedly installed on the front and rear sides of the well mechanism 1. The fixing bolts 1014 pass through the ventilation grid 1013 and the mounting base plate 1012 and are used to fix the ventilation grid 1013 on the outside of the mounting base plate 1012.

[0033] Furthermore, the ventilation mechanism 2 includes a connecting base 201, a filter screen 2011, a servo motor 2012, a ventilation fan blade 2013, an output helical gear 2014, a mounting base 2015, a transmission shaft 2016, and a transmission gear 2017.

By adopting the above technical solution, a stable mounting foundation is provided for other components of the ventilation mechanism 2.

[0034] Furthermore, there are two filter elements 2011, which are symmetrically fixed on the upper and lower sides of the connecting base 201. The servo motor 2012 is fixed on the lower side of the filter element 2011. The top of the servo motor 2012 is provided with an output shaft, which is located inside the two filter elements 2011. By adopting the above technical solution, air filtration and reasonable installation layout of the servo motor 2012 are achieved.

[0035] Furthermore, the ventilation fan blade 2013 is fixedly mounted on the outer wall of the top output shaft of the servo motor 2012. The servo motor 2012 and the ventilation fan blade 2013 together form a ventilation structure. The output helical gear 2014 is coaxially mounted on the top output shaft of the servo motor 2012. By adopting the above technical solution, air exchange between the pipe gallery and the outside world is realized, and power is provided for subsequent transmission.

[0036] Furthermore, there are two mounting bases 2015, which are symmetrically fixed on the left and right sides of the top surface of the connecting base 201. The transmission shaft 2016 is rotatably disposed on the inner side of the two mounting bases 2015. The transmission gear 2017 is fixedly disposed on the outer wall of the transmission shaft 2016. The transmission gear 2017 meshes with the output helical gear 2014 for transmission. By adopting the above technical solution, the power transmission and conversion are realized.

[0037] Furthermore, the transmission mechanism 3 includes an eccentric shaft 301, a first connecting rod 3011, a connecting support plate 3012, a second connecting rod 3013, a connecting guide shaft 3014, a guide frame 3015, and an inner cleaning brush 3016. The transmission mechanism 3 is a turntable structure. The transmission mechanism 3 is fixedly installed at both ends of the transmission shaft 2016, and the eccentric shaft 301 is fixedly installed on the outer wall of the transmission mechanism 3. By adopting the above technical solution, structural support is provided for the linkage of subsequent cleaning actions.

[0038] Furthermore, the first connecting rod 3011 is rotatably disposed on the outside of the eccentric shaft 301, the connecting support plate 3012 is fixedly disposed on the top end of the first connecting rod 3011, the second connecting rod 3013 is connected to the connecting support plate 3012, the connecting guide shaft 3014 is rotatably disposed on the top end of the second connecting rod 3013, the guide frame 3015 is fixedly disposed on the inner wall of the well mechanism 1, the inner cleaning brush 3016 is slidably disposed in the guide frame 3015 and is in contact with the inner wall of the light-transmitting window 101, a magnet is fixedly connected inside the inner cleaning brush 3016, and the inner cleaning brush 3016 is connected to the connecting guide shaft 3014. By adopting the above technical solution, the cleaning of the inner wall of the light-transmitting window 101 is achieved.

[0039] Furthermore, the wiping mechanism 4 includes a guide slider 401, an outer wiping brush 4011, and an adsorption magnet 4012. The guide slider 401 is symmetrically fixed on the outer wall of the wiping mechanism 4. The wiping mechanism 4 is slidably mounted on the outer wall of the well mechanism 1 via the guide slider 401. The outer wiping brush 4011 is fixedly mounted on the inner side of the wiping mechanism 4 and fits against the outer wall of the light-transmitting window 101. The adsorption magnet 4012 is fixedly mounted inside the outer wiping brush 4011 and is adsorbed and connected to the magnet in the inner cleaning brush 3016. By adopting the above technical solution, the synchronous cleaning of the outer wall and the inner wall of the light-transmitting window 101 is achieved.

[0040] When ventilation is required in the underground utility tunnel, the servo motor 2012 in the ventilation mechanism 2 is activated. As the core power source, the servo motor 2012's top output shaft starts to rotate, driving the ventilation fan blades 2013 fixed on the outer wall of the output shaft to rotate synchronously. The rotation of the ventilation fan blades 2013 generates airflow power, which, according to the actual ventilation needs, enables the ventilation operation of supplying fresh air to the shaft mechanism 1 or extracting polluted air from the underground utility tunnel, ensuring air circulation and environmental quality within the utility tunnel. At the same time, the two filter screens 2011 symmetrically arranged on the upper and lower sides of the connecting base 201 in the ventilation mechanism 2 will filter the air entering and exiting the shaft mechanism 1, intercepting dust, debris, and other particulate matter in the air, preventing pollutants from entering the utility tunnel or adhering to the surface of the ventilation components, and ensuring the clean operation of the ventilation system.

[0041] While the servo motor 2012 drives the ventilation fan blades 2013 to perform ventilation, the output helical gear 2014, which is coaxially mounted on its top output shaft, also rotates synchronously with the output shaft. Since the output helical gear 2014 meshes with the transmission gear 2017 fixed on the outer wall of the transmission shaft 2016, and the transmission shaft 2016 is supported by two mounting base plates 2015 symmetrically fixed on the left and right sides of the top surface of the connecting base 201, the rotation of the output helical gear 2014 will drive the transmission gear 2017 to rotate synchronously, thereby driving the transmission shaft 2016 to rotate stably inside the mounting base plate 2015, realizing the transmission and conversion of power from the servo motor 2012 to the transmission shaft 2016, providing power support for subsequent cleaning operations;

[0042] When the drive shaft 2016 rotates, the two symmetrically arranged transmission mechanisms 3 fixed at both ends of it rotate synchronously. The transmission mechanism 3 adopts a turntable structure, and the eccentric shaft 301 fixed on its outer wall moves in a circular motion with the turntable. The circular motion of the eccentric shaft 301 drives the first connecting rod 3011 rotatably connected to its outer side to move. The first connecting rod 3011 transmits power to the second connecting rod 3013 connected to it through the connecting support plate 3012 fixed at the top, causing the second connecting rod 3013 to generate a linkage motion. The connecting guide shaft 3014 rotatably connected to the top of the second connecting rod 3013... Driven by the linkage movement, the internal cleaning brush 3016 connected to it is pulled to slide back and forth along the guide frame 3015 fixed to the inner wall of the well mechanism 1. The guide frame 3015 provides precise guidance for the sliding of the internal cleaning brush 3016, ensuring that the internal cleaning brush 3016 is always in close contact with the inner wall of the light-transmitting windows 101 symmetrically arranged on the left and right sides of the well mechanism 1. During the reciprocating sliding process of the internal cleaning brush 3016, its bristles rub against the inner wall of the light-transmitting window 101, thereby wiping and cleaning the dust and stains attached to the inner wall, and avoiding the accumulation of dirt that affects the light transmission effect.

[0043] During the reciprocating sliding of the inner cleaning brush 3016 along the guide frame 3015, the magnets fixedly connected inside it will generate a continuous magnetic attraction. Since the magnetic block 4012 fixed in the outer wiping brush 4011 in the wiping mechanism 4 attracts the magnetic block in the inner cleaning brush 3016, this magnetic linkage enables the wiping mechanism 4 to reciprocate synchronously along the outer wall of the well mechanism 1 under the drive of the inner cleaning brush 3016 through the guide slider 401 symmetrically fixed on the outer wall. The guide slider 401 provides stable guidance for the sliding of the wiping mechanism 4, ensuring that the outer wiping brush 4011 is always in close contact with the outer wall of the light-transmitting window 101. During the reciprocating sliding of the outer wiping brush 4011 with the wiping mechanism 4, its bristles rub against the outer wall of the light-transmitting window 101, and simultaneously wipe and clean the dust and stains attached to the outer wall of the light-transmitting window 101, achieving a dual cleaning effect on the inner and outer walls of the light-transmitting window 101.

[0044] The shielding top cover 1011 fixed at the top of the shaft mechanism 1 adopts a conical structure. During the operation of the ventilation shaft, it can effectively block rainwater, fallen leaves and other external debris, preventing debris from entering the shaft mechanism 1 and causing blockage or damage to the components. At the same time, it prevents debris from accumulating on the surface of the light-transmitting window 101 and affecting light transmission. The mounting base plates 1012 symmetrically arranged on the front and rear sides of the shaft mechanism 1 are fixedly connected to the ventilation grid 1013 by fixing bolts 1014. The ventilation grid 1013 not only ensures the circulation of air inside and outside the shaft mechanism 1, but also further blocks larger debris from entering the shaft. Together with the shielding top cover 1011, it forms a double protection to ensure the stable operation of the various mechanisms inside the ventilation shaft.

[0045] Throughout the entire operation, the single power source of the servo motor 2012 achieves the linkage of the two major functions of ventilation and cleaning, without the need for an additional independent cleaning power device. The rotational power of the servo motor 2012 is transmitted to the transmission mechanism 3 through the transmission assembly consisting of the output helical gear 2014, the transmission gear 2017, and the transmission shaft 2016. Then, the rotational motion is converted into the reciprocating linear motion of the inner cleaning brush 3016 through the linkage assembly of the transmission mechanism 3. Finally, the magnetic adsorption linkage between the inner cleaning brush 3016 and the wiping mechanism 4 realizes the synchronous reciprocating cleaning motion of the outer wiping brush 4011. At the same time, the protective components of the shaft mechanism 1 and the filter components of the ventilation mechanism 2 work together to ensure the overall operational stability and cleanliness of the ventilation shaft. The power transmission and action linkage between the components are smooth and orderly. While completing the core function of ventilation and air exchange in the pipe gallery, the light-transmitting window 101 is continuously cleaned and maintained to ensure that the light-transmitting window 101 maintains good light transmission performance for a long time, thus achieving an organic combination of the four major functions of ventilation, lighting, cleaning, and protection.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
