Civil air defense poison gas treatment alarm device

Abstract

The utility model discloses a civil defense poison gas processing alarm device which comprises a shell, an absorption mechanism, an alarm mechanism and a switching mechanism. The shell is provided with a first air opening and a second air opening which penetrate through the civil air defense ventilation opening. The absorption mechanism comprises an air filter arranged at the first air opening; the alarm mechanism comprises a poison gas sensor arranged at the second air opening and a buzzer connected with the sensor. The switching mechanism comprises a wind shield and a driving assembly for driving the wind shield to block the first air opening or the second air opening. When no toxic gas exists at ordinary times, the air baffle blocks the first air opening and the second air opening to be opened for air circulation, when the toxic gas enters, the toxic gas can only enter the civil air defense facility through the air filter, and it is guaranteed that air can be used by indoor personnel for a short time. Therefore, the poison gas can be filtered while the poison gas is alarmed, and the safety of personnel in the civil air defense facility is effectively protected.

Description

Technical Field

[0001] The utility model relates to the field of civil air defense equipment, in particular to a civil air defense poison gas treatment alarm device. Background Art

[0002] Underground civil air defense projects are enclosed underground protective buildings with thick coverings built to ensure the shelter of personnel and materials, civil air defense command and medical rescue in wartime. Once dangerous situations such as fire, high temperature, smoke or toxic gas occur in civil air defense projects, harmful gases will quickly fill the underground space. However, the existing toxic gas alarm devices in civil air defense projects can only sound an alarm when toxic gas enters, but cannot take corresponding measures to deal with the toxic gas, and their functions are relatively simple. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a human air defense poison gas treatment alarm device, which can filter and treat the poison gas while issuing an alarm for the poison gas, effectively protecting the safety of personnel in the human air defense facility.

[0038] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0039] Reference below Figure 1-Figure 3 A human defense gas treatment alarm device is described in detail with a specific embodiment. It is worth noting that the following description is only an exemplary description, and not a specific limitation of the utility model.

[0040] like Figure 1-Figure 3 As shown, a human defense gas treatment alarm device includes a shell 100, an absorption mechanism, an alarm mechanism and a switching mechanism.

[0041] The housing 100 is provided with a first air vent 110 and a second air vent 120 that penetrate the air vent of the air defense system; the absorption mechanism includes an air filter 130 disposed at the first air vent 110; the alarm mechanism includes a poison gas sensor 140 disposed at the second air vent 120 and a buzzer 150 connected to the sensor; the switching mechanism includes a windshield 160 and a driving component that drives the windshield 160 to block the first air vent 110 or the second air vent 120. When there is no poison gas at ordinary times, such as Figure 2 As shown, the windshield 160 blocks the first air outlet 110, and the second air outlet 120 is opened for circulating air. When poisonous gas enters, the poisonous gas sensor 140 of the second air outlet 120 will detect it, and the buzzer 150 connected thereto will sound an alarm to notify relevant personnel. At the same time, the driving component of the switching mechanism will drive the windshield 160 to block the second air outlet 120. Figure 3 As shown, the poisonous gas is prevented from entering, and the first air outlet 110 is exposed. The poisonous gas needs to pass through the air filter 130 before entering the civil air defense facility, so as to ensure that the people in the room have air to use for a short time. Therefore, the poisonous gas can be filtered and processed while the alarm is issued for the poisonous gas, effectively protecting the safety of the people in the civil air defense facility.

[0042] Specifically, Figure 1As shown, the shape of the air filter 130 matches the shape of the first air outlet 110. In this way, the device ensures that the poisonous gas can enter the civil air defense facility only after passing through the air filter 130. Moreover, the shape of the first air outlet 110 is square. The first air outlet 110 is set in a square shape, which is conducive to the manufacture and installation of the air filter 130. Correspondingly, the shape of the second air outlet 120 matches the shape of the first air outlet 110. This is conducive to the drive component driving the windshield 160 to block the first air outlet 110 and the second air outlet 120.

[0043] It should be noted that if Figure 1 and Figure 2 As shown, the second air outlet 120 is provided with a mounting frame 170, and the alarm mechanism is installed on the mounting frame 170. Providing the second mounting frame 170 is conducive to installing the alarm mechanism on the second air outlet 120. Specifically, the mounting frame 170 is cross-shaped, including a vertically arranged cross bar 180 and a vertical bar 190, and the buzzer 150 is installed on the cross bar 180. The mounting frame 170 is arranged in a cross shape, which is firmly installed and is also conducive to the installation of the buzzer 150. Moreover, a mounting opening 200 is provided in the center of the mounting frame 170, and the poisonous gas sensor 140 is arranged at the mounting opening 200. Providing the mounting opening 200 in the center of the mounting frame 170 is conducive to installing the poisonous gas sensor 140 and is also conducive to detecting poisonous gas.

[0044] Furthermore, if Figure 1 As shown, the alarm mechanism further includes an alarm light 210, and the alarm light 210 and the buzzer 150 are respectively located on the crossbars 180 on both sides. The alarm mechanism is provided with an alarm light 210 to further remind relevant personnel when there is poisonous gas, and the crossbars 180 respectively located on both sides are conducive to installation.

[0045] It is understandable that activated carbon and multiple layers of filter cloth are provided in the air filter 130 (activated carbon and filter cloth are not shown in the figure). The activated carbon and filter cloth can effectively absorb and filter the poisonous gas to prevent the poisonous gas from entering the civil air defense facilities. It should be noted that the air filter 130 has a time limit for absorbing the poisonous gas and may become ineffective after a certain period of time.

[0046] It is worth mentioning that Figure 2 and Figure 3 As shown, the driving component is a cylinder 220. The cylinder 220 is used to drive the wind shield 160 to seal the first air outlet 110 or the second air outlet 120, which is easy to set and control.

[0047] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
