[0025] The length adjustment unit 3 includes a first groove 31 disposed on the outer wall of the collar 1 and a guide block 32 slidably disposed in the first groove 31 and fixedly connected to the inner sleeve 2.

[0026] The drive unit 4 is located on one side outside the body 200 of the leakage alarm device and is used to drive the guide blocks 32, which are distributed at both ends, to move towards each other or away from each other.

[0027] In a specific implementation, first, the water delivery pipeline 101 is bolted and connected on the outlet end of the fire pump 100, and then the inner sleeve 2 on one side of the leakage alarm device body 200 is installed on the end of the water delivery pipeline 101 away from the fire pump 100. Since the relative installation distance on the fire system pipeline is fixed, the driving unit 4 can generate driving force on both sides to drive the guide block 32 welded on the outer end of the inner sleeve 2 in the first sliding groove 31 machined on the sleeve ring 1 to move linearly, so as to adjust the relative length of the sleeve ring 1 and the inner sleeve 2, and meet the installation and fixation of the leakage alarm device body 200 between the water delivery pipeline 101 and the extension pipeline 102 with multiple installation distances, which is simple to operate.

[0028] After the installation of the water delivery pipeline 101 on one end of the leakage alarm device body 200, the length of the sleeve ring 1 and the inner sleeve 2 on the other end of the leakage alarm device body 200 is adjusted and determined, and then the inner sleeve 2 is bolted and fixed on the end of the extension pipeline 102.

[0029] It should be noted that the leakage alarm device body 200 is a device commonly used in current conventional technology, including but not limited to a pressure gauge and a buzzer alarm used in cooperation with the pressure gauge.

[0030] In an embodiment, the driving unit 4 includes a transmission shaft 431 rotatably arranged on one side outside the leakage alarm device body 200, and a gear 43 sleeved outside the transmission shaft 431.

In this way, by slotting and rotating the transmission shaft 431 on one side outside the leakage alarm device body 200 and sleeving the fixed gear 43 outside the transmission shaft 431, when the transmission shaft 431 is rotated, the gear 43 is rotated, so that the racks 42 on both sides of the gear 43 move away or close to each other, and then the insertion rod 41 welded on the end of the rack 42 moves in the first sliding groove 31, realizing the stable movement of the inner sleeve 2 in the inner wall of the sleeve ring 1, changing the relative length of the sleeve ring 1 and the inner sleeve 2, and being suitable for fixed installation with multiple installation distances.

[0031] In an embodiment, the outer end of the rack 42 is provided with a support horizontal plate 5. In this way, by slotting and installing a guide rail on the outer end of the rack 42 and installing a guide rail groove on the support horizontal plate 5 matched with the guide rail, when the rack 42 moves, the support horizontal plate 5 provides a stable support effect.

[0032] It should be noted that the support horizontal plate 5 is provided with two, and is respectively installed on the outer side of the two racks 42 distributed above and below.

[0033] In an embodiment, the support horizontal plate 5 is provided with guide rods 6 on both sides, and the outer part of the guide rods 6 on both sides is provided with fixing blocks. In this way, by welding the guide rods 6 on both sides of the support horizontal plate 5, and installing the fixing blocks on the outer part of the guide rods 6, and turning the guide slots on the fixing blocks correspondingly to the guide rods 6, when only moving the rack 42 on one side, the rack 42 that does not need to be moved and the support horizontal plate 5 connected with the rack 42 can be moved in the vertical direction by using the guide rods 6 connected with the fixing blocks and the inserting rod 41 movably inserted in the guide block 32, so that the rack 42 on this side is disengaged from the gear 43, and when rotating the transmission shaft 431, the rack 42 on one side is driven to move linearly by the gear 43, so as to realize the relative movement of the sleeve ring 1 and the inner sleeve 2 on one side, and meet the actual installation requirement.

[0034] In an embodiment, the outer protection plate 7 for protecting the driving unit 4 is arranged between the fixing blocks on both sides, and the outer protection plate 7 is provided with a second sliding groove 71 for limiting the linear movement of the guide block 32 correspondingly to the first sliding groove 31. In this way, by welding the outer protection plate 7 on the fixing blocks on both sides and turning the second sliding groove 71 on the outer protection plate 7, the transmission structure included in the driving unit 4 can be protected, and the movement of the guide block 32 is not affected.

[0035] In an embodiment, the outer end of the inner sleeve 2 is provided with a flange. In this way, by welding the flange on the outer end of the inner sleeve 2, the flange can be bolted and installed with the flange close to the end of the water conveying pipeline 101 or the extension pipeline 102, and the operation is simple.
