[0002] The outdoor hydrant is a water supply facility installed on the fire water supply network outside the building. It is mainly used for fire trucks to draw water from the municipal water supply network or the outdoor fire water supply network to implement fire extinguishing. It can also be directly connected to a water hose or a water gun to discharge water for fire extinguishing. It is one of the important fire-fighting facilities for fighting fires. Outdoor hydrants will be installed in the early stage of building construction. However, during the construction process, the water quality at the construction site is relatively dirty and contains some larger particles such as stones. During the use of the outdoor hydrant, the existing ordinary filter installed at the water inlet of the outdoor hydrant is easily damaged by the impact of large particles, which makes it easy for large particles to enter the outdoor hydrant and block the outdoor hydrant, or cause water leakage, and even damage the outdoor hydrant. In view of this, an in-depth study has been conducted on this issue, and thus this case has arisen. Utility Model Content

[0022] Correspondingly, the stainless steel woven mesh is made of 304 stainless steel.

[0023] During construction, the filter can be first installed at the water inlet of the outdoor plug, and after the construction is completed and before the site acceptance, the filter can be removed and replaced with an existing ordinary filter.

[0024] By combining the first filter screen 1 with the second filter screen 2, the first filter screen 1 and the second filter screen 2 are arranged in sequence along the direction of water inlet, which can achieve a double filtering effect and a double protection effect. At the same time, the first mesh sheet 11 and the second mesh sheet 21 made of stainless steel woven mesh are used, so that the first filter screen 1 and the second filter screen 2 have a strong structural strength, can better withstand the impact from large particles of debris, and are not easy to be damaged. In this way, large particles of debris are not easy to enter the outdoor plug and are not easy to block the outdoor plug, which effectively ensures the normal use of the outdoor plug during the construction process and is not easy to cause damage. At the same time, the use of the first annular rubber pad 12 and the second annular rubber pad 22 can facilitate the first filter screen 1 and the second filter screen 2 are stably installed at the outdoor plug water inlet, and can also play the role of sealing the connection flange; by adopting the separated first filter screen 1 and the second filter screen 2, it is convenient to make the first filter screen 1 and the second filter screen 2 separately, and at the same time, with the setting of the chimeric structure 3, it is convenient to realize the quick disassembly and assembly between the first filter screen 1 and the second filter screen 2. When the two are chimeric, the stable connection between the first filter screen 1 and the second filter screen 2 can be better guaranteed for subsequent use. In the process of construction and use, even if the first filter screen 1 is damaged, the second filter screen 2 can still play a corresponding filtering effect. At the same time, when repairing, only the first filter screen 1 needs to be replaced.

[0025] The interlocking structure 3 includes matching annular interlocking blocks 31 and annular interlocking grooves 32. A plurality of coaxially arranged annular interlocking blocks 31 are fixedly provided on one side surface of the first annular rubber pad 12, and the diameters of the plurality of annular interlocking blocks 31 increase sequentially from the inside to the outside. A plurality of coaxially arranged annular interlocking grooves 32 are fixedly provided on one side surface of the second annular rubber pad 22, and the diameters of the plurality of annular interlocking grooves 32 increase sequentially from the inside to the outside. The annular interlocking blocks 31 are detachably embedded in the corresponding annular interlocking grooves 32, thereby ensuring the stability of the interlocking connection between the first filter screen 1 and the second filter screen 2, and facilitating the disassembly and assembly of the first filter screen 1 and the second filter screen 2. Preferably, the number of the annular interlocking blocks 31 and the number of the annular interlocking grooves 32 are both 2-3.

[0026] The first filter screen 1 and the second filter screen 1 are both circular in shape, the first annular rubber pad 12 and the second annular rubber pad 22 are both rubber pads, the first mesh 11 and the first annular rubber pad 12 are vulcanized and fixed into an integrated structure, thereby ensuring the stability of the overall structure when the first mesh 11 and the first annular rubber pad 12 are fixedly connected, and the second mesh 21 and the second annular rubber pad 22 are vulcanized and fixed into an integrated structure, thereby ensuring the stability of the overall structure when the second mesh 21 and the second annular rubber pad 22 are fixedly connected.

[0027] In addition, a plurality of coaxially arranged first annular sealing protrusions 121 are fixedly provided on the first annular rubber pad 12 on a side surface away from the mosaic structure 3, and the diameters of the plurality of first annular sealing protrusions 121 increase sequentially from the inside to the outside. A plurality of coaxially arranged second annular sealing protrusions 221 are fixedly provided on the second annular rubber pad 22 on a side surface away from the mosaic structure 3, and the diameters of the plurality of second annular sealing protrusions 221 increase sequentially from the inside to the outside. Preferably, the number of the first annular sealing protrusions 121 and the number of the second annular sealing protrusions 221 are both 2-3.

[0028] The distance between the first mesh 11 and the second mesh 21 is 10-20 mm, thereby ensuring a cavity with a larger volume therebetween. The aperture of the first mesh 11 is 3-5 times the aperture of the second mesh 21 .

[0029] The thickness of the first annular rubber pad 12 is 3-6 times the thickness of the first mesh 11, and the thickness of the second annular rubber pad 22 is 3-6 times the thickness of the second mesh 21. The first mesh 11 is arranged on the side close to the first annular rubber pad 12 and away from the mosaic structure 3, and the second mesh 21 is arranged on the side close to the second annular rubber pad 22 and away from the mosaic structure 3. In this way, the distance between the first mesh 11 and the second mesh 21 can be close to the sum of the thicknesses of the first annular rubber pad 12 and the second annular rubber pad 22. Therefore, while ensuring that there is a certain size of distance between the first mesh 11 and the second mesh 21, the thickness of the first annular rubber pad 12 and the second annular rubber pad 22 will not be too thick.

[0030] The above are only some specific implementation methods of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
