[0002] In the field of drainage of civil air defense projects, a well-designed poison gas cutoff structure is conducive to ensuring the stable operation of the drainage system, while preventing poison gas from entering the interior of the civil air defense project building to ensure safety. Traditional civil air defense project poison gas cutoff structures mostly adopt the form of water seal wells. Water seal wells can effectively cut off the spread of poison gas through the drainage system, but will cause the poison gas to be stored in the water seal well. If the water seal well cover is not sealed tightly, or the seal of the well cover fails over time, the poison gas will easily leak through the water seal well into the civil air defense project. In addition, the sediment in the water seal well will also ferment to produce poison gas. The poison gas accumulates in the water seal well for a long time, which also poses a certain degree of threat to the safety of the water seal well maintenance personnel. Utility Model Content

[0022] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application.

[0023] Combine the following Figure 1 , the poisonous gas interception structure and collection system 100 of the civil air defense project provided in the embodiment of the present application is described in detail through a specific embodiment.

[0024] Please also read Figure 1 , Figure 1 It is a structural schematic diagram of the poisonous gas cutoff structure and collection system of the civil air defense project provided by the utility model. Figure 1 It is a structural schematic diagram of the poisonous gas cutoff structure and collection system for civil air defense engineering provided by the utility model. The poisonous gas cutoff structure and collection system 100 for civil air defense engineering provided by one embodiment of the utility model includes a water seal well 10, an inclined plate 20, a poisonous gas connecting pipe 30, a poisonous gas exhaust pipe 40 and a water seal tank 50. The water seal well 10 is used to collect poisonous gas; the inclined plate 20 is obliquely inserted into the water seal well 10, and the inclined plate 20, the water seal well 10 and the water body in the water seal well 10 jointly form a poisonous gas collection chamber 11; the poisonous gas connecting pipe 30 is connected to the poisonous gas collection chamber 11; the poisonous gas exhaust pipe 40 is connected to the poisonous gas connecting pipe 30; the water seal tank 50 is connected to the poisonous gas exhaust pipe 40.

[0025] By setting the water seal well 10 and the inclined plate 20, the poisonous gas is collected in the water seal well 10 to prevent it from spreading outward, thereby realizing the interception of the poisonous gas. The inclined plate 20 and the water body in the water seal well 10 together form a poisonous gas collection chamber 11, which collects the poisonous gas in the water seal well 10. Through the poisonous gas connecting pipe 30 and the poisonous gas exhaust pipe 40, the collected poisonous gas is discharged from the water seal well 10 to avoid excessive accumulation of poisonous gas in the water seal well 10. The water seal tank 50 is connected to the poisonous gas exhaust pipe 40 to ensure that the discharged poisonous gas is effectively collected and processed, thereby preventing the poisonous gas from leaking and causing harm. The poisonous gas interception structure and collection system of the civil air defense project are composed of the inclined plate 20, the water seal well 10, the poisonous gas connecting pipe 30, the poisonous gas exhaust pipe 40 and the water seal tank 50. Through such a setting, the interception, collection and discharge of the poisonous gas can be realized, thereby preventing the poisonous gas from leaking through the water seal well 10 and protecting the surrounding environment and the safety of personnel.

[0026] In some embodiments, two inclined plates 20 are provided, and the two inclined plates 20 are inserted into the water seal well 10 at an angle relative to each other to form two poisonous gas collection chambers 11. The two inclined plates 20 are inserted into the water seal well 10 at an angle relative to each other to form two poisonous gas collection chambers 11. Such a design can further improve the effect of poisonous gas collection and increase the capacity and stability of the poisonous gas collection chamber 11. By providing two inclined plates 20, poisonous gas can be collected and isolated more effectively, and the cutoff and collection efficiency of the system can be improved. At the same time, multiple poisonous gas collection chambers 11 can disperse the accumulation of poisonous gas and reduce the risk and possibility of leakage.

[0027] In some embodiments, two poisonous gas collection chambers 11 are connected by a poisonous gas connection pipe 30. Through the poisonous gas connection pipe 30, the poisonous gas can be transferred from one poisonous gas collection chamber 11 to another poisonous gas collection chamber 11, so as to ensure that the entire system can effectively collect and process the poisonous gas. In addition, after the poisonous gas is transferred from one poisonous gas collection chamber 11 to another poisonous gas collection chamber 11, it can be transferred to the water seal tank 50 through the poisonous gas exhaust pipe 40 in the poisonous gas collection chamber 11.

[0028] In some embodiments, one of the poison gas collection chambers 11 is connected to the poison gas exhaust pipe 40, and the other poison gas connection chamber transports the poison gas to one of the poison gas collection chambers 11 through the poison gas connection pipe 30, and transports the poison gas in one of the poison gas collection chambers 11 to the water seal tank 50 through the poison gas exhaust pipe 40.

[0029] One of the poisonous gas collecting chambers 11 is connected to the poisonous gas exhaust pipe 40, and the other poisonous gas collecting chamber 11 transports the poisonous gas to one of the poisonous gas collecting chambers 11 through the poisonous gas connecting pipe 30, and then the poisonous gas in one of the poisonous gas collecting chambers 11 is transported to the water seal tank 50 through the poisonous gas exhaust pipe 40. Through such an arrangement, the effective collection and treatment of the poisonous gas can be achieved. One of the poisonous gas collecting chambers 11 receives the poisonous gas from the other poisonous gas collecting chamber 11 through the poisonous gas connecting pipe 30, and the poisonous gas in the two collecting chambers is mixed and concentrated. Then, the poisonous gas in one of the collecting chambers is introduced into the water seal tank 50 through the poisonous gas exhaust pipe 40 for further treatment and processing. Among them, the water seal tank 50 can ensure that the poisonous gas is safely collected and stored to prevent the harm caused by its leakage into the environment.

[0030] In some embodiments, a poison gas storage tank 60 is further included, and the poison gas storage tank 60 is connected to the water seal tank 50 .

[0031] The poison gas storage tank 60 is a device specially used for storing poison gas. After being connected with the water seal tank 50, the storage capacity of the entire system can be increased. This ensures that there is enough space to store and process the poison gas when a large amount of poison gas is produced or a large amount of poison gas is produced in a short period of time. By transferring the poison gas in the water seal tank 50 to the poison gas storage tank 60, it can be avoided that the water seal tank 50 overflows when the amount of poison gas is too large. The poison gas storage tank 60 can provide a larger capacity to store poison gas and ensure the stable operation of the system.

[0032] Among them, the poison gas storage tank 60 is a container specially used for storing poison gas, which usually has a larger capacity and a tighter closure to prevent the leakage of poison gas. It is usually used for long-term storage or temporary storage of a large amount of poison gas for subsequent treatment or disposal. The water seal tank 50 is generally a device that uses water to seal and isolate the poison gas. Its main function is to prevent the poison gas from spreading outward through the pipeline, and to achieve the discharge of the poison gas and the stability of the water level through the outlet pipe and the inlet pipe. The poison gas storage tank 60 usually has a larger capacity and can store more poison gas. The poison gas collected in the water seal tank 50 is transferred to the storage tank, and the poison gas can be stored and managed more effectively. And the poison gas storage tank 60 usually has a tighter closure, which can effectively prevent the leakage of poison gas. Transmitting the poison gas to the storage tank can provide a higher safety guarantee and reduce the harm to the surrounding environment and personnel.

[0033] In some embodiments, a water outlet pipe 12 and a water inlet pipe 13 are also included, and both the water outlet pipe 12 and the water inlet pipe 13 are connected to the water seal well 10.

[0034] The water seal well 10 prevents the spread of poisonous gas by sealing with water. The water level in the water seal well 10 can be adjusted through the water outlet pipe 12 and the water inlet pipe 13 to maintain a stable water level in the water seal well 10. When the water level in the water seal well 10 is maintained at an appropriate level, the poisonous gas can be more effectively sealed and isolated to avoid leakage and harm.

[0035] Moreover, the flow of the water outlet pipe 12 and the water inlet pipe 13 can help regulate the pressure of the system. When the gas pressure in the water seal well 10 is too high, part of the gas can be discharged through the water outlet pipe 12 to reduce the pressure of the system. When the gas pressure in the water seal well 10 is too low, water can be added through the water inlet pipe 13 to increase the pressure of the system.

[0036] In some embodiments, an elbow 14 is provided on the outlet pipe 12 and the inlet pipe 13, and the bending angle of the elbow 14 is 90°. The outlet pipe 12 and the inlet pipe 13 are usually arranged horizontally or vertically. By providing the elbow 14, the outlet pipe 12 and the inlet pipe 13 can be inserted into the water body in the water seal well 10.

[0037] In some embodiments, the outlet pipe 12 and the inlet pipe 13 are inserted into the water seal well 10 after being passed through the inclined plate 20, and the outlet pipe 12 and the inlet pipe 13 are welded to the inclined plate 20. By welding the outlet pipe 12 and the inlet pipe 13 to the inclined plate 20, the connection strength and stability of the entire system can be increased. Welding is a high-strength connection method that can ensure a firm connection between the outlet pipe 12 and the inlet pipe 13 and the inclined plate 20, reducing the risk of loosening and leakage. In addition, welding the outlet pipe 12 and the inlet pipe 13 on the inclined plate 20 can reduce the risk of toxic gas leakage in the connection part. It can prevent the toxic gas in the toxic gas collection chamber 11 from leaking through the connection between the outlet pipe 12 and the inclined plate 20; and the toxic gas from leaking through the connection between the inlet pipe 13 and the inclined plate 20.
