The front door 4-2 is installed on the left side plate 4-6 through the hinge 4-7. The front door 4-2 is installed with the lock 4-3 between the right side plate 4-4. The box body 4 is provided with the transverse partition 4-8, and the transverse partition 4-8 divides the space in the box body 4 into two parts. The upper space is mainly used for placing the fire hose, and the lower space is mainly used for placing the fire gun, so as to prevent the fire hose and the fire gun from being extruded and deformed, and ensure that the fire extinguishing needs are met.

[0020] The embodiment also includes the water supply pipe 2 through and fixed to the left side plate 4-6, and the inner end of the water supply pipe 2 is located in the lower space and is connected with the fire hose adapter 3. Specifically, the inner end of the water supply pipe 2 is processed with external threads, the fire hose adapter 3 is processed with internal threads, and the fire hose adapter 3 is fixedly installed on the inner end of the water supply pipe 2 by interconnecting the external threads and the internal threads. The outer end of the water supply pipe 2 is welded with the water supply pipe flange 2-1. The water supply pipe flange 2-1 is connected with the fire water supply pipe 12 through the flange gate valve 1. Specifically, the two gate valve flanges 1-1 of the flange gate valve 1 are connected with the flange plate of the fire water supply pipe 12 and the water supply pipe flange 2-1 through each group of six bolts. The sealing surface of the gate valve flange 1-1 is processed with two sealing grooves, and the flange sealing ring is embedded in the sealing grooves.

[0021] The fire hose adapter 3 is also called a fire hose joint, a fire hose interface device or a water hose quick connector. The embodiment selects the KY65 fire hose joint.

[0022] Specifically, the flange gate valve 1, the water supply pipe 2, the box body 4 and the flange connecting bolt and nut are all made of stainless steel, so as to avoid underground water corrosion and meet the underground environment requirements. The two sealing grooves of the sealing surface of the gate valve flange 1-1 are 1mm wide, 0.5mm deep and V-shaped groove angle 45°, so as to meet the sealing installation requirements of the flange sealing ring. The flange sealing ring is made of high-pressure asbestos board, so as to prevent the flange sealing surface from leaking. The flange gate valve 1 of the embodiment selects the Z41Y-16R / DN65mm stainless steel gate valve.

[0023] As Figure 2 And Figure 3The rear side plate 4-9 is provided with a plurality of box positioning holes 4-9-1 with different heights, and each column of box positioning holes 4-9-1 has at least three, and five in the embodiment. The left column of box positioning holes corresponds to the right column of box positioning holes in height. The rear side plate 4-9 is fixedly provided with a box positioning plate 5. The box positioning plate 5 is provided with four positioning plate mounting holes, and the box positioning plate 5 is fixed to the rear side plate 4-9 through the fixing bolts 6 penetrating the positioning plate mounting holes and the box positioning holes 4-9-1. The installation height of the box 4 is adjusted by the positioning plate mounting holes corresponding to the box positioning holes with different heights. The four positioning plate mounting holes on the box positioning plate correspond to two box positioning holes in the first row and the second row in the embodiment.

[0024] In actual manufacture, the box positioning plate 5 is made of Q235B metal structural steel, which has good rigidity and cutting performance, and the specification size is L500mm* B200mm* δ10mm. The surface is manually rusted and brushed with epoxy zinc primer and finish paint.

[0025] As shown in the figure, Figure 3 The box positioning plate 5 is fixedly connected (usually welded) with two anchor rods 7 perpendicular to the box positioning plate 5. The embodiment further includes two anchor rod mounting holes in the rock wall 11. The outer ends (upper ends shown) of the two anchor rods 7 are inserted into the anchor rod mounting holes. Figure 3 The anchor rod mounting holes are drilled by a pneumatic rock drill, and the hole diameter and depth should be adapted to the diameter and fixed length of the anchor rod 7 to ensure the safety and reliability of the anchor rod.

[0026] Further, the part of the anchor rod 7 inserted into the anchor rod mounting hole is provided with a resin anchoring agent 9 between the anchor rod mounting hole wall. The resin anchoring agent 9 in the embodiment is CK3535 / 35*350mm resin anchoring agent (instead of ordinary cement cartridge), which can improve the safety and reliability of the anchor rod, and the anchor rod can bear load after fifteen minutes of setting time. The anchor rod 7 in the embodiment is selected as a ∮32mm / L=400mm threaded steel, which has a spiral protrusion on the outer surface, and the outer surface can be in close contact with the anchoring agent 9 during installation, which can fix the anchor rod 7 reliably and prevent the anchor rod 7 from falling out.

[0027] Further, the anchor rod 7 is provided with an anchoring agent blocking ring 8, which is located outside the resin anchoring agent 9 (underside shown) and in the anchor rod mounting hole. Figure 3 The anchoring agent blocking ring 8 in the embodiment is made of Q235B metal structural steel, which is inserted from the outer end of the anchor rod 7 and then enters the anchor rod mounting hole during installation, and is used to prevent the outflow of the anchoring agent 9 before forming.

[0028] Further, the anchor rod 7 is also provided with a positioning ring 10. The positioning ring 10 is located outside the anchor rod mounting hole and is attached to the rock wall 11. The inner diameter of the positioning ring 10 in this embodiment is ∮34mm, the outer diameter is ∮48mm, and the length is 5mm, which is used to seal the anchor rod mounting hole and position the anchor rod 7.

[0029] The unmarked metal member welding seam in the drawing is continuously welded by fillet welding, and the welding seam height is not less than the minimum connector thickness. After welding, check whether there are defects such as slag inclusion and pores in the welding seam, so that the metal member has sufficient connection strength.
