Description

Technical Field

[0001] This utility model relates to the field of fire hydrants, and more particularly to a fire hydrant with water pressure detection. Background Technology

[0002] Fire hydrants are an important part of the urban water supply system. They are usually directly connected to the municipal water supply network to ensure that sufficient water pressure and volume can be provided even when domestic and industrial water consumption surges during a fire.

[0003] The water pressure provided by fire hydrants directly determines the height and range of the water jet that a fire hose can spray. Therefore, a pressure testing connector is needed to detect the water pressure of the fire hydrant. For example, Chinese Patent Publication No. "CN221014333U" discloses a fire hydrant water pressure testing device, which relates to the field of water pressure testing equipment technology. The device includes a housing with a connection port and a hose interface at both ends. A pressure gauge is fixedly installed on the outer wall of the housing. A support frame is fixedly installed at the end of the housing away from the pressure gauge, and a rotating shaft is located inside the support frame. A limit box is movably installed on the outer wall of the rotating shaft, and one end of the limit box has a groove. A pull ring is located on the inner wall of the groove, and the other end of the pull ring has a storage bag. This invention uses a storage bag to collect water leaking from the connection port to the fire hydrant, solving the problem of workers having to use a plastic bag to collect water during static pressure testing. This prevents water from entering the fire hydrant box, causing a slippery and dirty floor, facilitating inspection, saving time and effort, and improving work efficiency.

[0004] In actual operation, the storage bag is rolled up by rotating the limiting box. However, considering that the limiting box and the device housing have been used for a long time or one of them is damaged, the whole thing needs to be replaced because it cannot be disassembled, which would be wasteful. In addition, there is no locking structure between the limiting box and the bracket. Therefore, in case of accidental pulling of the storage bag, the storage bag may accidentally come off the limiting box, causing inconvenience. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the lack of a locking structure between the limiting box and the bracket, and to propose a fire hydrant with water pressure detection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

One end of the support part is connected to the connection port of the fire hydrant body through the connector end, and a valve is fixedly connected to the other end of the support part.

[0008] The outer wall of the connector end is fixedly connected to a pressure valve, and the outer wall of the connector end is also detachably connected to a storage component through a connection structure. The storage component is used to store a water-collecting soft bag, and the water inlet of the water-collecting soft bag is connected to the water outlet of the valve.

[0009] The storage assembly includes a bracket and a storage component. A locking structure is provided between the storage component and the bracket, and the storage component stores the water-collecting soft bag through the locking structure.

[0010] Furthermore, the bracket is an elastic structure and ring-shaped, and the bracket has a relief groove formed through the outer wall, and the bracket is engaged in the recessed portion of the outer wall of the connector end through the relief groove;

[0011] The bottom of the bracket extends downward to form a pair of extensions, and the storage component is fixedly connected between the pair of extensions.

[0012] Furthermore, the connecting structure includes a pair of connecting straps, the opposite ends of the pair of connecting straps are respectively fixedly connected to the two arms of the bracket, and the opposite ends of the pair of connecting straps are respectively provided with connectors and through grooves;

[0013] The connector slides through the through groove to fix the free ends of a pair of connecting straps together.

[0014] Furthermore, the locking structure includes a winding rod, the middle end of which is rotatably connected to the interior of the midpoint of the storage component, and both ends of which are rotatably connected to the extensions on both sides.

[0015] The water-receiving soft bag has a pull rope fixedly connected to its tail end, and the pull rope is fixedly connected to the middle end of the winding rod.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-5 A fire hydrant with water pressure detection includes a fire hydrant body 1 and a pressure testing connector. The pressure testing connector includes a support part 2. One end of the support part 2 is connected to the connection port of the fire hydrant body 1 through a connector end 3. The other end of the support part 2 is fixedly connected to a valve 4.

[0028] The outer wall of the connector end 3 is fixedly connected to a pressure valve 5, and the outer wall of the connector end 3 is also detachably connected to a storage component 7 through a connection structure 6. The storage component 7 is used to store a water-collecting soft bag 8, and the water inlet of the water-collecting soft bag 8 is connected to the water outlet of the valve 4.

[0029] The storage component 7 includes a bracket 71 and a storage piece 72. A locking structure 9 is provided between the storage piece 72 and the bracket 71, and the storage piece 72 stores the water-collecting soft bag 8 through the locking structure 9.

[0030] In some embodiments, the pressure testing connector is existing technology. Its specific working method and principle are as follows: the pressure testing connector uses a valve connector with a pressure gauge to detect water pressure. It can be connected to a water pipe for dynamic pressure detection or static pressure detection. The static pressure at the hydrant outlet refers to the pressure borne at the hydrant outlet in the fire hydrant system.

[0031] Specifically, the water-collecting soft bag 8 is used to collect the water sprayed from the pressure testing connector to prevent water from spraying out during testing and causing the fire cabinet or the ground to become wet.

[0032] Furthermore, the bracket 71 is an elastic structure and is ring-shaped. The bracket 71 has a relief groove 711 formed through the outer wall. The bracket 71 is engaged in the recessed portion of the outer wall of the connector end 3 through the relief groove 711.

[0033] The bottom of the bracket 71 extends downward to form a pair of extensions 712, and the storage member 72 is fixedly connected between the pair of extensions 712.

[0034] Furthermore, the connecting structure 6 includes a pair of connecting straps 61, the opposite ends of the pair of connecting straps 61 are respectively fixedly connected to the two arms of the bracket 71, and the opposite ends of the pair of connecting straps 61 are respectively provided with a connector 62 and a through groove 63;

[0035] The connector 62 slides through the through groove 63 to fix the free ends of a pair of connecting straps 61 together.

[0036] In this embodiment, the bracket 71 is preferably made of a material with deformation capability such as rubber or plastic. Under the action of the relief groove 711, the bracket 71 is engaged with the recessed part around the connector end 3 by abutting deformation. Then, under the action of the connector 62 blocking the through groove 63, the bracket 71 can avoid separation from the connector end 3 in case of accident.

[0037] Furthermore, the connector 62 slides through the through groove 63 to fix the free ends of a pair of connecting straps 61 together. Specifically, the locking principle between buttons and buttonholes in the prior art can be referred to. Specifically, the connector 62 is often a small round or square accessory with a protruding part (such as a ball, flat protrusion or column). The through groove 63 is a narrow channel that is specially sewn or cut on the connecting strap 61, and its size and shape are just enough to accommodate the protruding part of the connector 62.

[0038] In the specific operation, when the connector 62 is aligned with the through groove 63 and a certain pushing force is applied, the protruding part of the connector 62 will pass through the through groove 63. The diameter of the protruding part of the connector 62 is usually slightly larger than the thickness of the fabric in the through groove 63, or the opening end of the through groove 63 will be narrowed / reinforced, which will form a physical barrier.

[0039] It should be noted that the bracket 71 is limited to the periphery of the connector end 3 by the connecting structure 6, but when the pressure testing connector is rotated to the fire hydrant body 1, the bracket 71 can avoid synchronous rotation by idling.

[0040] More specifically, the locking structure 9 includes a winding rod 91, the middle end of which is rotatably connected to the interior of the midpoint of the storage member 72, and the two ends of which are rotatably connected to the extensions 712 on both sides.

[0041] The water-receiving soft bag 8 is fixedly connected to a pull rope 81 at its tail end, and the pull rope 81 is fixedly connected to the middle end of the winding rod 91.

[0042] In general, a support arm 92 is rotatably connected to one end of the winding rod 91, and a connecting handle 93 is rotatably connected to the side of the free end of the support arm 92.

[0043] The extension 712 near the side of the support arm 92 has a straight groove 713 at the top. The support arm 92 is flipped so that the connecting handle 93 is stopped in the straight groove 713.

[0044] Finally, an elastic buckle 94 is provided on the outer side of the extension 712, and the snap-fit ​​end of the elastic buckle 94 snaps into the slot 95 at the end of the support arm 92.

[0045] In some embodiments, the water-receiving soft bag 8 is a soft bag, and its open end can be fixed to the water outlet end of the valve 4 by means of a rubber ring or a fixing rope.

[0046] Among them, the pull rope 81 is preferably an elastic rope. The rotating winding rod 91 winds up the water-absorbing soft bag 8 by winding the pull rope 81. Of course, a rubber ring can be set at the opening end of the water-absorbing soft bag 8. The rubber ring abuts against the storage component 72 to prevent the water-absorbing soft bag 8 from being completely stored in the storage component 72.

[0047] In specific operation, the elastic buckle 94 is unlocked, and then the support arm 92 is flipped over. The support arm 92 is driven to rotate through the connecting handle 93. At the same time as the support arm 92 rotates, the winding rod 91 is driven to rotate synchronously, and then the water-soft bag 8 is wound up.

[0048] Similarly, when the elastic buckle 94 engages with the support arm 92, the connecting handle 93 stops within the straight groove 713, thus preventing the winding rod 91 from rotating freely.

[0049] Working method: During operation, the bracket 71 is engaged with the recessed part around the connector end 3 by the abutment deformation under the action of the relief groove 711, and the connector 62 slides through the through groove 63 by abutment to fix the free ends of the pair of connecting straps 61.

[0050] Then, unlock the elastic buckle 94, flip the support arm 92, and after the connecting handle 93 is disengaged from the straight groove 713, the water-collecting soft bag 8 can be taken out and the open end of the water-collecting soft bag 8 is fitted onto the water outlet end of the valve 4.

[0051] The connector 3 is connected to the fire hydrant body 1. When the control water valve of the fire hydrant body 1 is opened, the water pressure inside the fire hydrant body 1 can be detected by the pressure valve 5, and the sprayed water is collected by the water receiving bag 8.

[0052] Finally, after draining, the support arm 92 is driven to rotate via the connecting handle 93, and the rotation of the support arm 92 simultaneously drives the winding rod 91 to rotate synchronously, thereby winding up the water-resistant soft bag 8.

[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
