DETAILED DESCRIPTION

[0016] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0017] like Figure 1 , Figure 2 and Figure 3 As shown, the height-adjustable fire hydrant is used to adjust the height of the water outlet of the fire hydrant so that the same fire hydrant can meet the use of more places with different installation requirements. Specifically, it includes a fire hydrant seat 1, which is arranged below the ground surface and is used to support and fix the entire structure. A fire hydrant lower branch pipe 2 is fixed on the fire hydrant seat 1, and the bottom end of the fire hydrant lower branch pipe 2 is fixedly connected to a water pipeline buried below the ground surface to supply water to the fire hydrant.

[0018] The top of the fire hydrant lower branch pipe 2 is movably sleeved with a fire hydrant upper branch pipe 3, and the top of the fire hydrant upper branch pipe 3 is provided with a water outlet. The length of the fire hydrant upper branch pipe 3 inserted into the fire hydrant lower branch pipe 2 is adjustable, so as to adjust the height of the water outlet to achieve the adjustability of the overall height of the fire hydrant to meet different application scenarios.

[0019] A lower branch pipe connector 4 is formed on the outer periphery of the top end of the lower branch pipe 2 of the fire hydrant, and the top end of the lower branch pipe connector 4 abuts against two upper branch pipe connectors 5 arranged opposite to each other, and the two upper branch pipe connectors 5 are respectively detachably connected to the lower branch pipe connector 4, and the two upper branch pipe connectors 5 are respectively sealed and held on the outer periphery of the upper branch pipe 3 of the fire hydrant, and the two upper branch pipe connectors 5 are detachably connected. The lower branch pipe connector 4 cooperates with the upper branch pipe connector 5 to achieve the fixation and retention of the upper branch pipe 3 of the fire hydrant after the height is adjusted.

[0020] Specifically, the upper branch pipe connector 5 includes a semi-annular connecting arc plate 51, and the inner arc edge of the connecting arc plate 51 abuts against the outer wall of the fire hydrant upper branch pipe 3. The connecting arc plate 51 is provided with a holding arc wall 52 extending upward on one side close to the fire hydrant upper branch pipe 3, and the holding arc wall 52 also abuts against the outer wall of the fire hydrant upper branch pipe 3. The setting of the holding arc wall 52 increases the contact area between the upper branch pipe connector 5 and the fire hydrant upper branch pipe 3, thereby helping to improve the firmness of the connection between the fire hydrant lower branch pipe 2 and the fire hydrant upper branch pipe 3.

[0021] In this embodiment, the top ends of the two connecting arc plates 51 are located on both sides of the upper branch pipe 3 of the fire hydrant and are fixed with docking vertical plates 53 respectively. The docking vertical plates 53 on the same side are detachably provided with vertical plate connection fasteners 54. Through the cooperation of the vertical plate connection fasteners 54 and the docking vertical plates 53, the detachable connection between the two upper branch pipe connectors 5 is realized, so as to facilitate the adjustment of the height of the upper branch pipe 3 of the fire hydrant, and the operation is simple and convenient. The side walls of the docking vertical plates 53 are respectively fixedly connected with the holding arc walls 52 at the corresponding places, which helps to improve the fixing strength of the docking vertical plates 53. Generally, the vertical plate connection fasteners 54 are configured as bolts and nuts for use. Correspondingly, the lower branch pipe connector 4 can also be configured as two symmetrical half-body structures.

[0022] A lip seal ring 6 is sandwiched between the two upper branch pipe connectors 5 and the fire hydrant upper branch pipe 3, and a seal ring groove for accommodating the lip seal ring 6 is respectively provided on the inner wall of the two upper branch pipe connectors 5. Through the provision of the lip seal ring 6, the sealing of the fire waterway formed by the fire hydrant lower branch pipe 2 and the fire hydrant upper branch pipe 3 is achieved to prevent water leakage and pressure relief at the connection between the two, thereby ensuring the smooth transportation of fire water.

[0023] Protruding clamping bosses 7 are respectively provided on the inner walls of the two upper branch pipe connectors 5, and the clamping bosses 7 are provided at the top of the connecting arc plate 51, and a branch pipe groove 8 is arranged on the outer wall of the fire hydrant upper branch pipe 3 to be clamped with the clamping bosses 7. When the two upper branch pipe connectors 5 are connected with the lower branch pipe connector 4, the connection strength between the fire hydrant lower branch pipe 2 and the fire hydrant upper branch pipe 3 is improved by the clamping cooperation between the clamping bosses 7 and the branch pipe grooves 8. The clamping bosses 7 can be set as an integrated arc-shaped boss arranged along the inner wall of the upper branch pipe connector 5, or can be set as a segmented convex block structure, and correspondingly, the branch pipe groove 8 can be set as an integrated annular groove, or can be set as an independent groove corresponding to the convex block structure.

[0024] A butt-joint through-hole arranged opposite to each other is provided through the lower branch pipe connector 4 and each of the upper branch pipe connectors 5, and a connector fastener 9 is provided for use with the butt-joint through-hole. The assembly of the lower branch pipe connector 4 and the two upper branch pipe connectors 5 is achieved by the cooperation between the connector fastener 9 and the butt-joint through-hole. Generally, the vertical plate connection fastener 54 is provided as a bolt and a nut for use with each other.

[0025] When adjusting the height of the fire hydrant, first remove the vertical plate connecting fasteners 54 and the connector fasteners 9, take down the two upper branch pipe connectors 5, insert or pull out the fire hydrant upper branch pipe 3 to a suitable length according to the adjustment requirements, and install and reset the upper branch pipe connector 5, the connector fasteners 9, the vertical plate connecting fasteners 54, etc. in sequence.

[0026] The description of the present invention is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific uses.
