Technical Field

[0001] The utility model relates to the technical field of alarm devices, in particular to a gate-opening alarm device special for a non-metered anti-danger gate. Background Art

[0002] Meterless prevention refers to fire-fighting water supply facilities for fire prevention. Since the water flow resistance of the water meter is large, which affects the fire water supply pressure, no water meter is installed in the valve well to measure the water consumption, hence the name "meterless prevention".

[0003] The meterless fire prevention valve is used to supply fire water when a fire occurs. It is not allowed to supply water for other purposes. There is no metered water meter installed on the water supply pipeline equipped with the meterless fire prevention valve, and the water consumption cannot be measured. There have always been some intentional water theft users who do not follow the water supply agreement to open the meterless fire prevention valve when no fire occurs. They open the meterless fire prevention valve privately at other times to steal the fire water source for other purposes, causing water fee losses for water supply companies, increasing water supply leakage rate, and wasting water resources. In order to solve the above problems, this application proposes a special gate opening alarm device for the meterless fire prevention valve. Utility Model Content

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1

[0026] Reference Figure 1-Figure 2 A gate opening alarm device for a non-metered anti-danger gate comprises a non-metered anti-danger gate body 1. Both ends of the non-metered anti-danger gate body 1 are fixedly connected with mounting flanges 2. Each mounting flange 2 is penetrated with a plurality of through holes, and the plurality of through holes are distributed at equal intervals. The top of the non-metered anti-danger gate body 1 is fixedly connected with a gate top 3. The top of the gate top 3 is fixedly connected with a fixing plate 4. The top of the fixing plate 4 is fixedly connected with a rotating handle 5. A pressure cover 6 is provided above the non-metered anti-danger gate body 1. The pressure cover 6 is arranged on the outer wall of the gate top 3, the fixing plate 4 and the rotating handle 5. The fixing plate 4 and the pressure cover 6 are penetrated with holes. There are two first through holes 7, and each pair of first through holes 7 is jointly installed with a first line lead seal 8. A second through hole 9 is opened through the rotating handle 5 and the pressure cover 6, and a second line lead seal 10 is installed on the second through hole 9. The inner wall of the pressure cover 6 is fixedly connected with a magnetic induction sensor 11, and the top of the fixed plate 4 is fixedly connected with a magnet 12. The magnetic induction sensor 11 and the magnet 12 are arranged in coordination. The top of the pressure cover 6 is fixedly connected with an alarm 13, and the top of the pressure cover 6 is fixedly connected with a signal transmitter 14. The pressure cover 6 and the signal transmitter 14 are installed and fixed by multiple bolts.

[0027] Further explanation: the pressure cover 6 is installed above the meter-free safety gate body 1 to form a protective shell. The first line lead seal 8 passes through the first through hole 7 to connect the fixed plate 4 and the pressure cover 6. If the pressure cover 6 is opened, the first line lead seal 8 will break, so that the opened valve has a clear opening mark; the second line lead seal 10 passes through the second through hole 9. If the pressure cover 6 is to be opened, the second line lead seal 10 must be broken first, so that the act of removing and using the pressure cover 6 has a clear removal mark; the magnetic induction sensor 11 senses the presence of the magnet 12 and monitors the displacement of the magnetic induction sensor 11 at all times. When the pressure cover 6 is rotated to open the valve, the magnetic induction sensor 11 fixed on the pressure cover 6 also rotates accordingly. The magnetic induction sensor 11 is separated from the magnet 12 and no longer senses the presence of the magnet 12. At this time, the alarm 13 emits an alarm light and an alarm sound, and a signal can be transmitted to the outside world through the signal transmitter 14 (the signal is transmitted to the computer data management system, the computer management system processes and saves the transmitted data, and reports it to the administrator through the human-computer interaction interface) to notify the water supply inspector to handle it in time.

[0028] Example 2

[0029] Reference Figure 3 The difference between this embodiment and embodiment 1 is that in this embodiment, a first sensor 15 is fixedly connected to the inner wall of the pressure cover 6, and a second sensor 16 is fixedly connected to the inner wall of the pressure cover 6. The first sensor 15 and the second sensor 16 are arranged separately from the magnet 12.

[0030] To further explain, the first sensor 15 and the second sensor 16 are arranged apart from the magnet 12, so that the magnet 12 cannot generate magnetic induction to the first sensor 15 and the second sensor 16, and the first sensor 15 and the second sensor 16 cannot sense the existence of the magnet 12 at all times; the first sensor 15 and the second sensor 16 are used to monitor external magnetic interference alarms. When a strong external magnet approaches the device, due to the action of the strong external magnetic field, the magnetic induction state of the magnet 12 remains unchanged, thereby shielding the displacement monitoring function of the magnet 12 on the magnetic induction sensor 11. The magnet 12 rotates with the pressure cover 6 to open the meterless safety gate body 1 without issuing an alarm signal. As the pressure cover 6 continues to rotate, the first sensor 15 and the second sensor 16 sense the approach of the strong magnet and issue a magnetic interference alarm signal to protect the normal monitoring function of the magnet 12 from being disturbed, so that the magnet 12 can continue to monitor the position information of the magnetic induction sensor 11.

[0031] Example 3

[0032] Reference Figure 4, this embodiment is different from embodiments 1 and 2 in that, in this embodiment, the top of the gland 6 is fixedly connected to a central processing unit 17, the top of the gland 6 is fixedly connected to a solar panel 18, the inner wall of the gland 6 is fixedly connected to a battery 19, the magnet 12 is electrically connected to the central processing unit 17, the central processing unit 17 is electrically connected to the alarm 13, the central processing unit 17 is electrically connected to the signal transmitter 14, and the solar panel 18 is electrically connected to the battery 19.

[0033] Example 4

[0034] This embodiment is different from embodiments 1, 2 and 3 in that the central processing unit 17 in this embodiment is arranged at the bottom inside the pressure cover 6, the inner wall of the pressure cover 6 is fixedly connected to a battery 19, the battery 19 is arranged at the bottom inside the pressure cover 6, the magnet 12 is electrically connected to the central processing unit 17, the central processing unit 17 is electrically connected to the alarm 13, the central processing unit 17 is electrically connected to the signal transmitter 14, and the solar panel 18 is electrically connected to the battery 19; since the central processing unit 17 is arranged at the bottom inside the pressure cover 6, by extending the length of the connecting wire and connecting it with the magnet 12, the alarm 13 and the signal transmitter 14, it is avoided that the central processing unit 17 fails to alarm due to the rapid disassembly of the pressure cover 6 and the removal of the battery 19.

[0035] To further explain, the solar panels 18 can convert solar energy into electrical energy and store it in the battery 19. The battery 19 can supply power to various electrical components. The central processing unit 17 can process and judge the information, monitor the status and analyze it in real time. This technology is existing technology and will not be repeated here.
