Description

Technical Field

[0001] This utility model relates to the field of odor emission, specifically to an automatic odor emission structure for pipeline networks. Background Technology

[0002] Inspection wells, as key ancillary structures in urban underground pipe networks, directly affect the operational efficiency and maintenance convenience of the network through their function, structure, and synergy with the network. Inspection wells are typically installed at pipe junctions, bends, changes in pipe diameter or slope, drop structures, and at regular intervals along straight pipe sections to ensure the maintainability of the pipe network.

[0003] However, when sewage is discharged, odors tend to accumulate in the inspection wells. Therefore, staff often need to open the well covers regularly to release the odors and prevent them from accumulating and causing safety hazards. However, this process is time-consuming and labor-intensive. Electric exhaust fans are often needed to release the odors. However, there are many inspection wells, most of which are outdoors and widely distributed. If only electric fans are used for coverage, the cost will be high. Utility Model Content

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0027] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0028] In the existing technology, when sewage is discharged, odor tends to accumulate in the inspection well 1. Therefore, it is often necessary for staff to open the well cover 5 regularly to discharge the odor in the inspection well 1 to avoid the accumulation of odor and the resulting safety hazards. However, this process is time-consuming and labor-intensive. Electric exhaust fans 8 are often needed to discharge odor. However, there are many inspection wells 1, most of which are outdoors and widely distributed. If only electric power is used for coverage, the cost will be high.

[0029] Based on the above problems, this embodiment provides an automatic odor emission structure for pipeline networks, such as... Figures 1-2 As shown, it includes:

[0030] Inspection well 1 has an exhaust port 11 circumferentially opened on its inner side;

[0031] The emission assembly 2 includes an exhaust channel 21, an exhaust pipe, and a non-powered vent cap 23. The exhaust channel 21 is located on the outer peripheral surface of the inspection well 1 and is connected to multiple exhaust ports 11. One end of the exhaust pipe is connected to the exhaust channel 21, and the other end is connected to the non-powered vent cap 23.

[0032] In this embodiment, the inner wall of the inspection well 1 is provided with 6-10 vents 11, preferably 8, so that the odor accumulated in the inspection well 1 can be discharged from the vents 11 at different locations. The vents 11 cooperate with the emission assembly 2 to realize the automatic emission of odor. The emission assembly 2 is equipped with a non-powered vent cap 23, which eliminates the need for personnel to open or close the well cover 5 to discharge odor. On the other hand, the non-powered vent cap 23 works entirely by natural wind power and thermal pressure difference, requiring no electricity or manual operation and consuming zero energy, thus improving resource utilization. In addition, the non-powered vent cap 23 has a simple structure, with no motors, bearings and other vulnerable parts, requiring almost no maintenance and having a long service life. Compared with traditional electric ventilation equipment, the maintenance cost is lower.

[0033] The specific working process is as follows: When the outdoor natural wind blows the hood, the fan blades inside the non-powered hood 23 generate centrifugal force during rotation, reducing the surrounding air pressure and creating a negative pressure zone (the air pressure inside the hood is lower than the air pressure inside the inspection well 1). Under the action of the pressure difference, the odor inside the inspection well 1 is discharged outside the inspection well 1 through the exhaust channel 21 and then through the first exhaust pipe 22. In addition, the fan blades of the non-powered hood 23 are arc-shaped fan blades that are narrower on the inside and wider on the outside, with gaps between the blades, which can not only prevent dust and rain but also make efficient use of wind power.

[0034] As one of the preferred technical solutions, to improve the odor emission efficiency in the inspection well 1, the following configuration is provided: multiple first exhaust pipes 22 and non-powered vent caps 23 are provided, and multiple first exhaust pipes 22 are evenly distributed on the exhaust channel 21 and connected to the exhaust channel 21. In this embodiment, the number of first exhaust pipes is 4.

[0035] As one of the preferred technical solutions, to prevent foul odors from flowing back into the inspection well 1, a one-way valve 4 is installed on the first exhaust pipe 22. The one-way valve 4 is a valve that only allows gas to flow in one direction; the one-way valve 4 can prevent pressure leakage and maintain stable system pressure.

[0036] As one of the preferred technical solutions, such as Figure 2 As shown, the exhaust channel 21 has a ring structure. Specifically, this embodiment provides multiple exhaust ports 11 arranged in a ring. To ensure that the exhaust channel 21 is connected to each exhaust port 11, the exhaust channel 21 is set as a ring. The ring design can integrate multiple exhaust branches into a single ring structure, reducing space occupation.

[0037] As a preferred technical solution, a guide plate 3 is provided at the connection point between the exhaust channel 21 and the plurality of first exhaust pipes 22. Specifically, the guide plate 3 includes two inclined plates arranged in a V-shape, which are distributed at both ends of the connection point between the first exhaust pipe 22 and the exhaust channel 21. Under the guidance of the guide plate 3, the odorous airflow can enter the first exhaust pipe 22 more quickly.

[0038] As one of the preferred technical solutions, the exhaust port 11 is tapered. The gradually narrowing channel of the exhaust port 11 accelerates the exhaust airflow during its flow, allowing for more efficient discharge and reducing exhaust resistance. It also facilitates connection with the first exhaust pipe 22, reducing the risk of leakage and simplifying maintenance.

[0039] As one of the preferred technical solutions, a manhole cover 5 is detachably installed on the top of the inspection well 1. The manhole cover 5 is used to seal the well opening to prevent foreign objects or personnel from falling in. It is usually made of steel, cast iron, or composite materials and has pressure resistance, anti-theft, and waterproof functions. In addition, the manhole cover 5 can be opened to facilitate personnel to enter the inspection well 1 for maintenance and inspection.

[0040] As one of the preferred technical solutions, since the non-powered vent cap 23 relies entirely on wind power or thermal pressure difference to operate, when the wind power is low or there is no wind, the odor in the inspection well 1 cannot be effectively discharged. To solve this problem, it is set that: the exhaust channel 21 is also connected to a second exhaust pipe 7, and an electric exhaust fan 8 is installed at the connection between the second exhaust pipe 7 and the exhaust channel 21.

[0041] Furthermore, a monitoring component 6 is provided at the bottom of the manhole cover 5 to monitor the odor concentration inside the inspection well 1 and control the electric exhaust fan 8 to turn on or off.

[0042] Specifically, the monitoring component 6 includes a controller 61 and an electrochemical sensor 62; the electrochemical sensor 62 is used to monitor the odor concentration in the inspection well 1, and the controller 61 is connected to the electrochemical sensor 62 and the electric exhaust fan 8 respectively, and is used to receive the signal from the electrochemical sensor 62 and control the electric exhaust fan 8 to turn on or off.

[0043] The above-described working process is as follows: The electrochemical sensor 62 is used to monitor the odor concentration inside the inspection well 1. The working principle of the electrochemical sensor 62 is based on an electrochemical reaction, converting the chemical signal of the target gas into an electrical signal for detection. Specifically, the odor enters the sensor through a diffusion pore (such as a microporous membrane or hydrophobic barrier) and reaches the surface of the working electrode. The oxidation or reduction reaction of the working electrode generates a current proportional to the gas concentration. The current flows through the external circuit to the counter electrode, forming a loop. Measuring this current allows for direct calculation of the gas concentration. When the measured gas concentration exceeds a safe value, the electrochemical sensor 62 transmits a signal to the controller 61, which then controls the electric exhaust fan 8 to start operating, discharging the odor from the inspection well 1.

[0044] By combining the electric exhaust fan 8 and the non-powered vent cap 23, the normal discharge of odor from the inspection well 1 is ensured, thus guaranteeing the safety of the environment inside the well.

[0045] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
