Abstract
Description
Technical Field
[0001] This utility model relates to a ventilation device for underground utility tunnels. Background Technology
[0002] Underground utility tunnels, also known as "common trenches," are public tunnels built underground in cities to centrally lay municipal pipelines such as electricity, communications, broadcasting and television, water supply, drainage, heating, and gas. Underground utility tunnels can effectively prevent the phenomenon of "zipper roads," allowing technicians to carry out emergency repairs, maintenance, and capacity expansion of various pipelines without repeatedly excavating the road surface; at the same time, they can greatly reduce pipeline repair time.
[0003] However, existing underground utility tunnels generally have poor ventilation, resulting in poor air quality inside. This makes it difficult for workers to obtain oxygen during installation and maintenance. Therefore, it is necessary to design corresponding technical solutions to address these issues. Summary of the Invention
[0004] The purpose of this utility model is to provide a ventilation device for underground utility tunnels. It has a reasonable structure and achieves the exchange of outside air with the air inside the utility tunnel by setting up an air intake mechanism and an air exhaust mechanism, so as to improve the air quality inside the utility tunnel.
[0005] To achieve the above objectives, the technical solution of this utility model is to design a ventilation device for underground integrated pipe gallery, including the pipe gallery body, a protective cover, an exhaust mechanism, and an air intake mechanism.
[0006] The protective cover is fixed to the top of the pipe gallery body, and ventilation openings are provided at both ends of the protective cover.
[0007] The ventilation mechanism includes a main ventilation pipe located at the center inside the protective cover. An exhaust fan is installed inside the main ventilation pipe, and exhaust branch pipes are connected to the top two sides of the main ventilation pipe. The two exhaust branch pipes are connected to the two ventilation openings respectively. The pipe gallery body is provided with an exhaust port connected to the main ventilation pipe.
[0008] The air intake mechanism includes two air intake pipes installed inside the protective cover. Each of the two air intake pipes is equipped with an air intake fan. The two air intake pipes are located on both sides of the main exhaust pipe and are connected to the two ventilation openings. The pipe gallery body is provided with an air intake port connected to the air intake pipes.
[0009] Preferably, both the exhaust branch pipe and the air inlet pipe include an inclined section, which is inclined upward from the vent towards the center of the protective cover.
[0010] Preferably, a filter plate is provided at the vent.
[0011] Preferably, the top of the filter plate passes through the protective cover and is connected to a fixing plate. The protective cover has an insertion port for the filter plate to pass through, and the inside of the protective cover has a socket corresponding to the insertion port. The bottom of the filter plate is inserted into the socket.
[0012] Preferably, the fixing plate is detachably connected to the protective cover by screws.
[0013] The advantages and beneficial effects of this utility model are as follows: It provides a ventilation device for underground integrated pipe gallery with a reasonable structure. By setting up an air intake mechanism and an air exhaust mechanism, it realizes the exchange of outside air with the air inside the pipe gallery body, so as to improve the air quality inside the pipe gallery body.
[0014] Furthermore, by setting inclined sections in the exhaust branch pipes and air inlet pipes, it is possible to effectively prevent external rainwater from entering the interior of the utility tunnel through the pipes.
[0015] In addition, by installing filter plates, the intake and exhaust air can be filtered and purified. Attached Figure Description

[0017] Figure 2 yes Figure 1 Enlarged view of point A in the middle. Detailed Implementation
[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0019] The specific technical solution of this utility model is as follows:
[0020] like Figure 1 and Figure 2 As shown, a ventilation device for underground utility tunnels includes a tunnel body 100, a protective cover 1, an exhaust mechanism, and an intake mechanism.
[0021] The protective cover 1 is fixed to the top of the pipe gallery body 100, and ventilation openings 2 are provided at both ends of the protective cover 1.
[0022] The exhaust mechanism includes an exhaust main pipe 3 located at the center of the protective cover 1. An exhaust fan 4 is installed inside the exhaust main pipe 3, and exhaust branch pipes 5 are connected to the top two sides of the exhaust main pipe 3. The two exhaust branch pipes 5 are respectively connected to the two ventilation openings 2. An exhaust port 6 connected to the exhaust main pipe 3 is provided on the pipe gallery body 100.
[0023] The air intake mechanism includes two air intake pipes 7 installed inside the protective cover 1. Each of the two air intake pipes 7 is equipped with an air intake fan 8. The two air intake pipes 7 are located on both sides of the exhaust main pipe 3, and the two air intake pipes 7 are connected to the two ventilation openings 2. The pipe gallery body 100 is provided with an air intake 9 connected to the air intake pipes 7.
[0024] This utility model discloses a ventilation device for underground utility tunnels, in which a protective cover 1 protects the exhaust and intake mechanisms. When the exhaust mechanism is in operation, the exhaust fan 4 is activated to discharge air from inside the tunnel body 100 through the main exhaust pipe 3 and branch exhaust pipes 5. When the intake mechanism is in operation, the intake fan 8 is activated to draw outside air into the tunnel body 100 through the intake pipe 7, thereby achieving air exchange between the outside and inside the tunnel body 100 and improving the air quality inside the tunnel body 100.
[0025] Furthermore, both the exhaust branch pipe 5 and the air inlet pipe 7 include an inclined section 10, which is inclined upward from the ventilation opening 2 toward the center of the protective cover 1. By adopting the above solution, it is possible to effectively prevent external rainwater from entering the interior of the pipe gallery body 100 through the pipes.
[0026] Furthermore, a filter plate 11 is provided at the ventilation opening 2. By adopting the above solution, the incoming and exhaust air can be filtered and purified.
[0027] Furthermore, the top of the filter plate 11 penetrates the protective cover 1 and is connected to a fixing plate 12. The protective cover 1 has an insertion port 13 for the filter plate 11 to pass through, and the interior of the protective cover 1 has a socket 14 corresponding to the insertion port 13. The bottom end of the filter plate 11 is inserted into the socket 14. By adopting the above scheme, the filter plate 11 can be positioned and installed.
[0028] Furthermore, the fixing plate 12 is detachably connected to the protective cover 1 by screws 15. By adopting the above solution, the filter plate 11 can be disassembled and assembled, thereby facilitating the cleaning or replacement of the filter plate 11.
[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
