Description

Technical Field

[0001] This utility model relates to the field of smart fire protection technology, and in particular to a smart fire valve cap. Background Technology

[0002] Smart fire protection uses electronic devices to monitor the usage of various water supply facilities, thereby enabling comprehensive fire protection planning.

[0003] In existing technologies, caps are typically installed at water supply facilities to prevent unauthorized water theft. Professionals need to unlock the cap by swiping a card and then use a wrench with a hexagonal groove to open the valve and draw water. However, sanitation workers from municipal units often need to draw water during their work. Carrying a wrench is inconvenient, as it requires placing it on their sanitation vehicle, making it difficult to access. Furthermore, sanitation workers who work on foot without a sanitation vehicle often cannot carry a wrench with them when drawing water. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a smart fire valve cap, which aims to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A smart fire valve cap is provided for installation on a water valve. The smart fire valve cap includes a lower cover body connected to the water valve and an upper cover body rotatably connected to the lower cover body. The lower cover body includes a first base plate and a fixing block connected to the first base plate. The upper cover body includes a second base plate rotatably connected to the fixing block. The fixing block has a through hole for a wrench handle to pass through, and the wall of the through hole has a self-locking structure for fixing the wrench.

[0007] According to one aspect of the above technical solution, the side of the upper cover near the lower cover is recessed to form a relief groove for the hexagonal recessed block of the wrench to enter, and the size of the relief groove is larger than the size of the hexagonal recessed block of the wrench.

[0008] According to one aspect of the above technical solution, a sealing gasket is provided at the wall of the through hole, and the sealing gasket is used to fit tightly against the handle of the wrench.

[0009] According to one aspect of the above technical solution, the edge of the upper cover is disposed on the edge of the lower cover.

[0010] According to one aspect of the above technical solution, an electromagnetic lock is provided on the side of the lower cover away from the upper cover, and a lock groove is formed in the recess on the side of the upper cover close to the electromagnetic lock. The lock cylinder of the electromagnetic lock extends through the lower cover toward the upper cover so that the lock cylinder of the electromagnetic lock is inserted into the lock groove.

[0011] According to one aspect of the above technical solution, the self-locking structure includes a tapered rod disposed within the fixed block, a spring connecting the tapered rod and the fixed block, and an insertion groove recessed in the wall of the through hole. The tapered portion of the tapered rod is used to insert into the insertion hole on the wrench and the insertion groove in the wall of the through hole.

[0012] According to one aspect of the above technical solution, the smart fire valve cap also includes a smart card reader module, which is electrically connected to the electromagnetic lock.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] By installing smart fire valve caps to cover the water valves, malicious water extraction can be prevented. When professionals collect water legally, they unlock the upper and lower covers by swiping a card. Then, they open the upper cover. Since the fixing block is fixed to the first base plate of the lower cover, the wrench will not rotate with the upper cover. Next, the wrench is pulled out from the through hole and used to rotate the water valve to collect water. After water collection, the wrench is reinserted into the through hole and fixed by a self-locking structure to prevent the wrench from moving in the through hole and jamming the upper and lower covers, making them unable to open. Finally, the upper cover is placed on top of the lower cover, and the card is swiped again to lock the upper and lower covers together.

[0015] This invention allows the wrench to be left directly in the smart fire valve cap after each water draw, eliminating the need to take the wrench with you each time and avoiding inconvenience and the situation of forgetting to bring the wrench. Attached Figure Description

[0028] Please see Figures 1 to 6The image shows a smart fire valve cap according to the first embodiment of this utility model, which is used to install on a water valve 20. The smart fire valve cap includes a lower cover 11 connected to the water valve 20 and an upper cover 12 rotatably connected to the lower cover 11. The lower cover 11 includes a first base plate 40 and a fixing block 13 connected to the first base plate 40. The upper cover 12 includes a second base plate 41 rotatably connected to the fixing block 13. The fixing block 13 has a through hole 136 through which the handle 141 of a wrench 14 passes. The wall of the through hole 136 is provided with a self-locking structure for fixing the wrench 14.

[0029] Understandably, by setting a smart fire valve cap to cover the water valve 20, malicious water extraction can be prevented. When professionals extract water legally, they unlock the upper cover 12 and lower cover 11 by swiping a card. Then, they open the upper cover 12. Since the fixing block 13 is fixed to the first base plate 40 of the lower cover 11, the wrench 14 will not rotate with the upper cover 12. Next, the wrench 14 is pulled out from the through hole 136, and the water valve 20 is rotated using the wrench 14 to extract water. After extraction, the wrench 14 is reinserted into the through hole 136, and the wrench 14 is fixed by a self-locking structure to prevent it from moving in the through hole 136 and jamming the upper cover 12 and lower cover 11, making them unable to open. Finally, the upper cover 12 is placed on top of the lower cover 11, and the card is swiped again to lock the upper cover 12 and lower cover 11 together.

[0030] This invention allows the wrench 14 to be left directly in the smart fire valve cap after each water draw, eliminating the need to take the wrench 14 with you each time, thus avoiding inconvenience and the situation of forgetting to bring the wrench 14.

[0031] Specifically, in this embodiment, the upper cover 12 has a recessed relief groove 122 on the side near the lower cover 11, which allows the hexagonal recessed block 142 of the wrench 14 to enter. The size of the relief groove 122 is larger than the size of the hexagonal recessed block 142 of the wrench 14. A sealing gasket 131 is provided at the hole wall of the through hole 136, and the sealing gasket 131 is used to fit tightly with the handle 141 of the wrench 14.

[0032] Understandably, the groove in the hexagonal recessed block 142 is used to open the water valve 20. It protrudes from the wrench 14. Therefore, in order to prevent the hexagonal recessed block 142 from hitting the water valve 20, the hexagonal recessed block 142 needs to be placed facing upwards when placing the wrench 14. An avoidance groove 122 is provided on the upper cover 12 to accommodate the hexagonal recessed block 142. Since the upper cover 12 and the lower cover 11 of this application adopt a flip-type hinge, the upper cover 12 does not close parallel to the lower cover 11. Therefore, it is necessary to consider that the avoidance groove 122 should not hit the edge of the hexagonal recessed block 142 when flipping the hinge. Therefore, its size is designed to be larger than the avoidance groove 122. The function of the sealing gasket 131 is to prevent rainwater from entering the interior of the upper cover 12 and the lower cover 11 through the through hole 136 during rainy weather, which would cause water accumulation.

[0033] Preferably, the edge of the upper cover 12 covers the edge of the lower cover 11.

[0034] Understandably, the size of the upper cover 12 is slightly larger than that of the lower cover 11, and the upper cover 12 and the fixing block 13 are actively connected by a hinge structure. In this way, when the upper cover 12 is flipped down, its edge can completely cover the edge of the lower cover 11, so that rainwater can flow out along the edge of the upper cover 12 and will not seep into the interior of the upper cover 12 and the lower cover 11.

[0035] Furthermore, the lower cover 11 is provided with an electromagnetic lock 111 on the side away from the upper cover 12, and the upper cover 12 is recessed on the side near the electromagnetic lock 111 to form a lock groove 121. The lock cylinder 112 of the electromagnetic lock 111 extends through the lower cover 11 toward the upper cover 12 so that the lock cylinder 112 of the electromagnetic lock 111 is inserted into the lock groove 121. The smart fire valve cap also includes a smart card swiping module 31, which is electrically connected to the electromagnetic lock 111.

[0036] As is understandable, this embodiment uses the water valve 20 on a fire hydrant as an example. We cover the original fire hydrant with the outer casing 30, leaving only the water valve 20 exposed. Then, we install the smart fire valve cap of this utility model on the outer casing 30, and install a smart card reader module 31 on the outer casing 30. Then, we install an electromagnetic lock 111 on the lower cover 11. Cards are issued to those with water access, such as firefighters and sanitation workers. When water is needed, the staff places the card on the card reader of the smart card reader module 31, triggering the lock cylinder 112 of the electromagnetic lock 111 to retract, no longer locking the lock groove 121. The staff actively flips open the upper cover 12 and removes the wrench 14. After taking water, the wrench 14 is placed into the through hole 136, and the upper cover 12 is flipped down until it contacts the lower cover 11. The card is swiped again, causing the lock cylinder 112 of the electromagnetic lock 111 to lock the lock groove 121 again. The wiring between the smart card reader module 31 and the electromagnetic lock 111 is done inside the outer casing 30.

[0037] Furthermore, the self-locking structure includes a tapered rod 133 disposed within the fixing block 13, a spring 134 connecting the tapered rod 133 and the fixing block 13, and an insertion groove 132 recessed in the wall of the through hole 136. The tapered portion of the tapered rod 133 is used to insert into the insertion hole 143 on the wrench 14 and the insertion groove 132 in the wall of the through hole 136.

[0038] Understandably, when the handle 141 of the wrench 14 is inserted into the through hole 136, one end of the handle 141 will contact the conical surface of the tapered rod 133, pushing the tapered rod 133 upwards until the handle 141 passes smoothly. When the insertion hole 143 on the handle 141 moves to the position of the tapered rod 133, the tapered rod 133 falls down and is located in the insertion groove 132. At this point, the worker can feel resistance when trying to move the handle 141, thus fixing the wrench 14. Then, the upper cover 12 can be flipped down. If a passerby tries to forcibly move the wrench 14, it can only move a small distance, and then the hexagonal fixing block 13 will block it due to the presence of the avoidance groove 122. When it is necessary to remove the wrench 14, the worker applies a little force so that the insertion hole 143 on the wrench 14 can push the tapered rod 133 up along the conical surface of the tapered rod 133, and the wrench 14 can be removed smoothly. It should be noted that the outer part of the through hole 136 has a variable cross section. The larger cross section is used to accommodate the sealing gasket 131. The through hole 136 is provided with a mounting hole 135 for accommodating the spring 134 and the tapered rod 133.

[0039] It should be noted that, since the wrench 14 and the cap are bound together, the wrench 14 can be made of stainless steel and have an insertion hole 143 at the center of gravity to ensure the balance of the wrench 14 after it is fixed.

[0040] In summary, the smart fire valve cap in the above embodiments of this utility model allows the wrench to be left directly in the smart fire valve cap after each water draw, eliminating the need to take the wrench with you each time and avoiding inconvenience and the situation of forgetting to bring the wrench.
