Abstract
The utility model discloses an air tightness detection device for civil air defense door, but including the basin of a holding civil air defense door, put the bracket that can support the civil air defense door in the basin, the bracket top surface is less than the surface of water 1-3cm in the basin, still includes the cover that induced drafts, and cover lower extreme opening and civil air defense door upper surface adaptation induced drafts, and the cover upper end that induced drafts is connected with the air compressor machine through the aspiration channel. This an air tightness detection device for people's air defense door conveniently detects people's air defense door gas tightness.
Description
The technical field is as follows:
the utility model relates to a people's air defense door field specifically says a gas tightness detection device for people's air defense door.
Background art:
the existing civil air defense door is simple to detect, the civil air defense door is fixed on an iron plate, then an air inlet pipe and an air outlet pipe are connected to the iron plate, the civil air defense door is ventilated and detected through the air inlet pipe, but the detection only can see whether the device leaks air under the condition of rapid pressure change to generate great influence on the accuracy of a detection result, in other words, the detection is difficult to accurately detect the small-amplitude air leakage.
The utility model has the following contents:
the utility model aims to solve the technical problem that a conveniently detect air tightness detection device that is used for people's air defense door of people's air defense door gas tightness is provided.
The technical solution of the utility model is that, a gas tightness detection device for civil air defense door is provided, but including the basin of a holding civil air defense door, place the bracket that can support the civil air defense door in the basin, the bracket top surface is less than the surface of water 1-3cm in the basin, still includes the cover that induced drafts, and cover lower extreme opening and civil air defense door upper surface adaptation induced drafts, and the cover upper end of induced drafts is passed through the aspiration channel and is connected with the air compressor machine.
Compared with the prior art after the structure more than adopting, the utility model has the advantages of it is following: place the people's air defense door on the bracket, then place the cover that induced drafts on the people's air defense door, utilize the air compressor machine to inhale into the negative pressure with the cover that induced drafts, if the air tightness of people's air defense door is not good, water can ooze up to can judge the gas tightness of people's air defense door directly perceivedly, simultaneously, this operation is also simple.
Preferably, the bracket is a rectangular bracket, the length and width of which are adapted to the civil air defense door.
Preferably, the outer edge of the bracket is provided with an upward folded flange, and the bracket is also uniformly distributed with overflowing holes through which water can flow.
Furthermore, the air suction cover is of a horn-shaped structure with a large lower part and a small upper part.
Description of the drawings:
fig. 1 is a usage state diagram of the present invention.
The specific implementation mode is as follows:
the invention will be further explained with reference to the drawings and the detailed description below:
as shown in fig. 1, the air tightness detection device for the civil air defense door comprises a water tank 1 capable of containing the civil air defense door, water is contained in the water tank 1, a bracket 2 capable of supporting the civil air defense door 6 is placed in the water tank 1, the top surface of the bracket 2 is lower than the water surface 2cm in the water tank, the air suction cover 3 is further included, the lower end opening of the air suction cover 3 is matched with the upper surface of the civil air defense door, and the upper end of the air suction cover 3 is connected with an air compressor 5 through an air suction pipe 4. Specifically, the bracket is a rectangular bracket, the bracket is formed by welding angle steel, the length and the width of the bracket are matched with the civil air defense door, the outer edge of the bracket is provided with a flange which is turned upwards, and the bracket is also uniformly provided with overflowing holes through which water can flow. In addition, the air suction cover is of a horn-shaped structure with a large bottom and a small top, an electric hoist can be arranged on the house beam for conveniently placing the air suction cover, the end face of the opening end of the air suction cover is a plane and can be bonded with an elastic sealing strip, so that the air suction cover can be better matched when placed at the edge of the air defense door, and the air suction effect of the air suction cover is better. In order to conveniently move the air suction cover, the air suction pipe is a telescopic plastic corrugated pipe.
During the use, place the people's air defense door on the bracket for surface submergence in aqueous under the people's air defense door, then will induced draft the cover and place on the people's air defense door, then utilize the negative pressure to induced draft, if the air tightness of people's air defense door is not good, water can leak people's air defense door upper surface, thereby can judge the gas tightness of people's air defense door directly perceived, the device easy operation, it is convenient, judge the accuracy.
The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. All the equivalent structures or equivalent flow changes made by using the contents of the specification and the attached drawings of the utility model are included in the patent protection scope of the utility model.
