Description

TECHNICAL FIELD

[0001] The utility model relates to the field of anti -theft device especially relates to the anti -theft water device for no -meter danger gate. BACKGROUND

[0002] No -meter danger refers to the fire -fighting water supply facility of fire danger, it is a valve well actually, it includes valve well and a mechanical gate valve. Because the water gauge's overwater resistance is big, influences fire -fighting water supply pressure, therefore does not install water gauge in valve well to measure water consumption.

[0003] No -meter danger gate valve is in the state of closing and locking lead seal normally. Users must not open the lead seal and open the no -meter danger valve, and when users need to test the internal fire -fighting facilities, they should notify the water supply enterprise to send people to open the no -meter danger valve for testing. When a fire occurs, users open the no -meter danger valve for fire extinguishing.

[0004] No -meter danger is to supply fire -fighting water when a fire occurs, and it is not allowed to supply water for other purposes. The water supply pipeline equipped with no -meter danger gate valve does not install a water meter, and the water consumption cannot be measured. Only when fire needs to use fire -fighting water source to extinguish fire, the no -meter danger gate valve can be opened to supply water for fire extinguishing.

[0005] However, there are some users who intentionally steal water. They do not use the no -meter danger gate valve when a fire occurs according to the water supply agreement. They privately remove the lead seal and open the no -meter danger gate valve to steal the fire -fighting water source for other purposes. This causes water fee loss of the water supply enterprise, increases the water leakage rate, and wastes water resources. CONTENT OF THE UTILITY MODEL

[0036] The bottom disc 5 is provided with a wire hole 9 for the data line of the sensor 4 to extend out of the whole device.

[0037] Furthermore, the top surface of the bottom disc 5 is provided with a bracket 10 for mounting the sensor 4.

[0038] In this embodiment, the bracket 10 is provided in an n shape, and two threaded holes are formed in the top end of the bracket 10 to facilitate mounting the sensor 4 on the bracket 10 by bolts; in another embodiment, the bracket 10 is provided in a horizontally placed L shape, and two half-threaded holes are symmetrically formed in the top end of the bracket 10 to facilitate mounting the sensor 4 on the bracket 10 by bolts.

[0039] Furthermore, the data line of the sensor 4 extends downward out of the whole device through the wire hole 9 and is connected to an RTU remote terminal, and a sheath made of stainless steel soft tube is provided on the data line of the sensor 4.

[0040] In this embodiment, the sensor 4 includes a main contact S1, a first auxiliary contact S2 and a second auxiliary contact S3, a VCC line and a GND line, and the main contact S1, the first auxiliary contact S2 and the second auxiliary contact S3 all adopt Hall chips.

[0041] The gate head 3 includes a square head 11 and a protective cover 12, the protective cover 12 is provided as an open shell at the lower part, during installation, the protective cover 12 and the bottom disc 6 of the gate valve cover 2 form a protective shell, forming a relatively closed protective shell for the sensor 4, the sensor 4 cannot be accessed from below the protective cover 12, and external interference magnets cannot approach the sensor 4, such design does not affect the normal operation of the switch gate, and can play a protective role for the sensor 4, thereby generating magnetic disturbance to the sensor 4.

[0042] A clearance hole 13 is formed in the top surface of the protective cover 12, the bottom end of the square head 11 is welded in the clearance hole 13, and the bottom surface of the square head 11 is flush with the inner top wall of the protective cover 12, the gate head 3 is installed above the gate valve cover 2 by bolts, and the protective cover 12 covers the sensor 4 therein to play a protective role for the sensor 4, preventing external force from damaging the sensor 4, disassembling the sensor 4 and using a small magnet to interfere with the sensor 4 at close range.

[0043] Further, an inductive magnet 14 is arranged on the inner top of the gate head 3, and the position of the inductive magnet 14 corresponds to the main contact S1, specifically, the inductive magnet 14 is above the main contact S1 and on the same circumference with the main contact S1; the distance between the inductive magnet 14 and the first auxiliary contact S2 and the second auxiliary contact S3 is greater than the magnetic field range of the inductive magnet 14, so that the inductive magnet 14 cannot generate magnetic induction on the first auxiliary contact S2 and the second auxiliary contact S3; specifically, the sensor 4 is coupled with the RTU remote terminal, is powered by the RTU remote terminal, and realizes interactive signals with the RTU; under normal circumstances, the inductive magnet 14 is above the main contact S1, the main contact S1 is subjected to magnetic induction under the magnetic field, and outputs a low level to the RTU remote terminal, at this time, the electric signals output by the main contact S1, the first auxiliary contact S2 and the second auxiliary contact S3 are normal signals and are in an alarm state without alarm.

[0044] When the valve is opened, the inductive magnet 14 moves away from above the main contact S1, the main contact S1 is not subjected to magnetic induction, and then the main contact S1 outputs a high level, which is an abnormal signal, and the RTU remote terminal receives the high level electric signal of the main contact S1, and then sends an alarm to the computer management module.

[0045] If a magnetic field is close to the first auxiliary contact S2 and the second auxiliary contact S3, and the first auxiliary contact S2 and the second auxiliary contact S3 are subjected to magnetic induction, the first auxiliary contact S2 and the second auxiliary contact S3 output a low level to the RTU remote terminal, which is an abnormal signal, and the RTU remote terminal receives the low level electric signal sent by the first auxiliary contact S2 and the second auxiliary contact S3, and then sends an alarm to the computer management module.

[0046] After receiving the alarm, the management personnel arrives at the scene immediately to stop the water stealing behavior or attempt, so that the non-meter anti-risk alarm valve returns to the normal closing alarm state, thereby protecting the normal monitoring function of the main contact S1.

[0048] Further, in order to prevent someone from attempting to cut the wire to damage the gate opening alarm function and achieve the purpose of opening the gate without alarm, the utility model designs a wire cutting alarm function, and the main contact S1 outputs a low level under the normal alarm state, and the first auxiliary contact S2 and the second auxiliary contact S3 output a high level, specifically:

[0049] ①Cut power line VCC alarm function: in the usual state of alert, the first auxiliary point S2, the second auxiliary point S3 output high level normal signal. When cutting off the power VCC line, the first auxiliary point S2, the second auxiliary point S3 output low level, which is an abnormal signal, and send an alarm.

[0050] ②Cut GND line alarm function: in the usual state of alert, the main contact S1 output low level normal signal. When cutting off the GND line, the main contact S1 output high level, which is an abnormal signal, and send an alarm.

[0051] ③Cut S1 line or whole line together cut alarm function: in the usual state of alert, the main contact S1 output low level, the first auxiliary point S2, the second auxiliary point S3 output high level, output normal signal and no alarm. When cutting off the S1 signal line or whole line together, S1 output high level, which is an abnormal signal, and send an alarm.

[0052] The working principle and beneficial effects of the utility model are:

[0053] The non-meter danger alarm valve is in the closed state, in which state, the inductive magnet 14 on the gate head 3 is located directly above the main contact S1 of the sensor 4, the inductive magnet 14 and the main contact S1 of the sensor 4 keep relative static, the main contact S1 of the sensor 4 senses the existence of the inductive magnet 14, and monitors the displacement of the inductive magnet 14 at all times.

[0054] When the gate head 3 is rotated to open the valve, the inductive magnet 14 fixed on the gate head 3 also rotates with the gate head 3, after the main contact S1 of the sensor 4 monitors the displacement of the inductive magnet 14, the RTU remote terminal connected with it through the data line sends an opening gate alarm signal to the computer management module.

[0055] In the utility model, since the inductive magnet 14 cannot produce magnetic induction to the first auxiliary point S2 and the second auxiliary point S3, the first auxiliary point S2 and the second auxiliary point S3 cannot sense the existence of the inductive magnet 14 at all times, the first auxiliary point S2 and the second auxiliary point S3 are used to monitor the external magnetic interference alarm, specifically: when an external strong magnet approaches the sensor 4, due to the effect of the external strong magnetic field, the magnetic induction state of the main contact S1 remains unchanged, thereby shielding the monitoring function of the main contact S1 to the displacement of the inductive magnet 14, the inductive magnet 14 rotates with the gate head 3 to open the valve main contact S1 and does not send an alarm signal, at this time, after the first auxiliary point S2 and the second auxiliary point S3 sense the approaching of the strong magnet and send a magnetic interference, the RTU remote terminal sends a strong magnetic interference alarm signal to the computer management module, thereby protecting the normal monitoring function of the main contact S1 from being disturbed.

[0056] In addition, the utility model also adds the first lead seal line and the second lead seal line, so that there is clear evidence for opening the valve and disassembling the gate head 3.

[0057] Specifically, the first lead seal line passes through the first lead seal hole 17, the third lead seal hole 18 on the gate head 3 and the second lead seal hole 15, the fourth lead seal hole 16 on the gland, seals the closed valve, if the emergency gate is opened, the first lead seal line will be broken, so that the opened valve has a clear opening mark.

[0058] The second lead seal line passes through the fifth lead seal hole 19, the sixth lead seal hole 20, seals the bolt for fixing the gate head 3, if the bolt is to be disassembled, the second lead seal line must be broken first, so that the behavior of disassembling the gate head 3 has a clear disassembly mark of the broken lead seal line.

[0059] In summary, in the utility model, the setting of the protective cover can prevent external force from damaging the sensor 4, disassembling the sensor 4 and using a small magnet to interfere with the sensor 4 at close range. The special gate head 3 is fixed with the gate rod by a bolt, when external force tries to disassemble the gate head 3, the bolt must be unscrewed and the gate head 3 is disassembled, the inductive magnet 14 is also disassembled with the gate head 3, at this time, the sensor 4 monitors the displacement of the magnet and sends an alarm signal, and leaves a lead seal disassembly mark, so that the timely feedback of the valve opening state is realized, the water supply enterprise can grasp the valve state in time, and the occurrence of the water stealing behavior is effectively prevented.

[0060] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the utility model, and not to limit them; although the utility model has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
