Description

Technical Field

[0001] The present invention relates to the field of gas control, and particularly to an intelligent and safe gas inlet system for households. Background Art

[0002] With the improvement of living standards, the use of gas is becoming more and more popular in rural areas. In order to supply gas to rural residents uniformly, gas companies will lay gas pipelines in rural areas. The gas pipelines include a main gas supply pipeline and a gas supply branch pipeline leading into residents' homes. A gas meter is installed on the gas supply branch pipeline to display the gas consumption. Existing gas meters include diaphragm gas meters, intelligent gas meters, etc. For diaphragm gas meters, the staff of the gas company need to visit households to read the meters and calculate the gas fees payable by users based on the copied gas data. However, due to the low building density in rural areas and the remoteness of some buildings, it is difficult and troublesome to read the meters, increasing the operating costs of gas companies. Therefore, gas companies usually choose intelligent gas meters, which automatically send gas consumption data to the gas company, and users can choose to pay gas fees on a mobile terminal (mobile phone) or at a payment point designated by the gas company.

[0003] Currently, intelligent gas meters include a meter housing and a controller, and the controller is installed inside the meter housing. Some intelligent gas meters need to be replaced regularly. Therefore, when replacing the intelligent gas meter, the controller will be replaced accordingly. However, at this time, the controller is not damaged and can still continue to work, which results in the replacement of a well-functioning controller, leading to waste of resources and increasing the replacement costs for users and gas companies. Summary of the Invention

[0004] The present invention aims to provide an intelligent and safe gas inlet system for households to solve the problem of waste of resources caused by the replacement of the controller when replacing existing intelligent gas meters.

[0005] To achieve the above object, the present invention adopts the following technical solution: An intelligent and safe gas inlet system for households includes a main gas supply pipeline and a plurality of gas supply branch pipelines. Each gas supply branch pipeline is connected to a control mechanism, and the control mechanism is connected to a gas meter. The gas meter has an inlet pipe and an outlet pipe. The control mechanism includes a housing, a control part, and a blocking part. The housing is separated from the gas meter. The housing includes a first housing and a second housing. The control part includes a chip and a flow sensor. The chip is used to obtain the data monitored by the flow sensor and is installed in the first housing. The blocking part is installed in the second housing. A gas transmission pipe is provided on one side wall of the second housing. The top end of the gas transmission pipe is communicated with the gas supply branch pipeline, and the bottom end of the gas transmission pipe is communicated with the inlet pipe or the outlet pipe of the gas meter. A blocking plate is provided inside the gas transmission pipe. First and second ventilation holes communicating with the inside of the second housing are provided on the side wall of the gas transmission pipe. The blocking plate is located between the first and second ventilation holes. The blocking part can seal the second ventilation hole and is controlled by the chip.

[0006] The side wall of the second housing facing the first housing is provided with a first threaded through hole, and the side wall of the first housing facing the second housing is provided with a through hole opposite to the first threaded through hole; the blocking part is electrically connected with an electrical connector, the electrical connector is threadedly connected in the first threaded through hole, the electrical connector can extend into the through hole, and the electrical connector is electrically connected with the chip;

[0007] The first housing and the second housing are detachably connected. The side wall of the second housing facing the first housing is provided with two parallel sliding rails, and the side wall of the first housing facing the second housing is provided with a sliding groove for the sliding rails to slide.

[0008] The principle and advantages of this solution are as follows: In this solution, the housing in the control mechanism is separated from the gas meter. When replacing the gas meter, the housing and the components inside the housing can be retained and continue to be used, avoiding waste of resources and reducing the replacement costs for gas companies and users.

[0009] Secondly, in this solution, the flow sensor monitors the gas flow. The chip is used to obtain the data monitored by the flow sensor and can control the blocking part to work in the case of abnormal gas flow (the gas usage is positively correlated with the gas flow), block and seal the second ventilation hole, and realize the automatic shutdown of the gas, avoiding continuous intake of gas in case of abnormality, thus avoiding accidents such as a large amount of gas leakage, with high safety and reliability. In addition, through the sliding connection of the sliding rails and the sliding grooves, the detachable connection of the first housing and the second housing is realized. When the first housing and the second housing are detachably connected, the first housing and the second housing can be separated, which is convenient for workers to separately install the control part and the blocking part, improving the assembly efficiency. And when the electrical connector is installed in the first threaded through hole, the electrical connector extends into the through hole, thereby fixing the first housing and the second housing and preventing relative sliding between the first housing and the second housing. In addition, when the first housing or the second housing is damaged, a new first housing or second housing can be replaced, avoiding replacing the first housing and the second housing together and reducing the maintenance cost.

[0010] Moreover, in this solution, since the housing includes a first housing and a second housing, and the chip of the control part is installed in the first housing and the blocking part is installed in the second housing, when opening the first housing to repair the components inside the first housing, it will not affect the second housing, that is, the components inside the first housing can be repaired without closing the gas pipeline, which is convenient for operation.

[0011] Preferably, as an improvement, the gas supply branch pipeline includes a branch main body and a branch sub-pipeline. One end of the branch main body is provided with an external thread section, the other end of the branch main body is provided with an internal thread section, and the distance from one end of the branch main body to the connection part of the branch main body and the branch sub-pipeline is greater than or less than the distance from the other end of the branch main body to the connection part of the branch main body and the branch sub-pipeline.

[0012] In this solution, in the gas supply branch pipeline, the distance from one end of the branch pipe main body to the connection point between the branch pipe main body and the branch pipe is different from the distance from the other end of the branch pipe main body to the connection point between the branch pipe main body and the branch pipe. A number of gas supply branch pipelines are connected in sequence, that is, one end of a gas supply branch pipeline with an external thread section is threadedly connected to one end of the previous gas supply branch pipeline with an internal thread section. At this time, enough installation space can be left between the branch pipes of adjacent two gas supply branch pipelines for the control mechanism and the gas meter, avoiding the use of a tee and a straight pipe, thereby reducing the connection points in the gas inlet pipeline, and further reducing the possibility of gas leakage from the pipeline connection points.

[0013] Preferably, as an improvement, a chip installation structure is provided inside the first housing. The chip installation structure includes two sets of clamping components arranged oppositely. Each set of clamping components includes two clamping plates, and the two clamping plates and the side wall of the first housing form a limiting groove.

[0014] In this solution, the chip installation structure is used to install the chip. The chip is clamped into the two limiting grooves, thereby fixing the chip inside the first housing and preventing the chip from shaking.

[0015] Preferably, as an improvement, the side wall of the gas transmission pipe on the second housing is detachably connected to the second housing. Ear plates are provided on the outer peripheral wall of the second housing, and a number of second threaded through holes are opened in the ear plates. A number of installation holes corresponding to the second threaded through holes are opened in the side wall of the gas transmission pipe on the second housing, and anti-theft screws are threadedly connected to the second threaded through holes.

[0016] In this solution, the anti-theft screw passes through the installation hole and is threadedly connected to the second threaded through hole, thereby detachably connecting the side wall of the gas transmission pipe on the second housing to the second housing, so as to open the second housing to perform maintenance work on the components inside the second housing.

[0017] Preferably, as an improvement, a groove is opened on the side wall of the second housing facing the gas transmission pipe, and a sealing ring is installed in the groove.

[0018] In this solution, when the side wall of the gas transmission pipe on the second housing is installed on the second housing, the sealing ring can improve the sealing performance of the installation place, thereby improving the sealing performance of the second housing and preventing gas from leaking from the second housing.

[0019] Preferably, as an improvement, when the bottom end of the gas transmission pipe is communicated with the gas inlet pipe of the gas meter, a manual valve is installed on the gas transmission pipe.

[0020] In this solution, a manual valve is installed on the gas transmission pipe so that the user or the staff can manually close the pipeline to stop the intake of gas.

[0021] Preferably, as an improvement, the control part further includes a network communication module.

[0022] In this solution, the chip is used to obtain the gas consumption data (gas flow data) monitored by the flow sensor, and the chip can control the operation of the electric valve according to the gas consumption data. The chip is used to send the gas consumption data monitored by the flow sensor to the cloud platform through the network communication module. The chip is used to receive the instructions sent by the cloud platform through the network communication module, and the chip can control the operation of the electric valve according to the instructions, thus facilitating the intelligent and safe management of users' gas use by the gas company.

[0039] Embodiment 1

[0040] This embodiment is basically as Figure 1 shown: An intelligent and safe gas inlet system for households includes a main gas supply pipeline 1 and a plurality of branch gas supply pipelines 2. Each branch gas supply pipeline 2 is connected to a control mechanism, and the control mechanism is connected to a gas meter 3. The gas meter 3 has a gas inlet pipe 310 and a gas outlet pipe 320. The control mechanism includes a housing 4, a control unit, and a blocking unit. The housing 4 is separated from the gas meter 3. The housing 4 includes a first housing 410 and a second housing 420. As shown in Figure 2 combination, the control unit includes a chip 5, a battery 6, and a flow sensor. The chip 5 is used to obtain the data monitored by the flow sensor. The battery 6 is electrically connected to the electrical circuit of the chip 5 through a wire. As shown in Figure 3 combination, the blocking unit includes an electric valve 7. The chip 5 and the battery 6 are installed in the first housing 410, and the electric valve 7 is installed in the second housing 420. Specifically, the electric valve 7 is installed on the inner surface of the right side wall of the second housing 420 by screws. In this embodiment, the chip 5 is of the CC2640 model, the electric valve 7 is of the WFJ-4 model (suitable for G2.5 diaphragm gas meters), and the flow sensor is a Hall element of the MT8631 model.

[0041] In combination with Figure 1 , Figure 3 and Figure 4As shown, an air delivery pipe 8 is integrally formed on the right side wall of the second housing 420. The top end of the air delivery pipe 8 communicates with the air supply branch pipe 2, and the bottom end of the air delivery pipe 8 communicates with the intake pipe 310 of the gas meter 3. In this embodiment, the air supply branch pipe 2 includes a branch pipe main body 210 and a branch pipe sub - pipe 220. The left end of the branch pipe main body 210 is provided with an external thread section, and the right end of the branch pipe main body 210 is provided with an internal thread section. The distance from the left end of the branch pipe main body 210 to the connection point between the branch pipe main body 210 and the branch pipe sub - pipe 220 is less than the distance from the right end of the branch pipe main body 210 to the connection point between the branch pipe main body 210 and the branch pipe sub - pipe 220. The outer diameter of the middle part of the branch pipe main body 210 is smaller than the outer diameter of the end part of the branch pipe main body 210, thereby reducing the weight of the air supply branch pipe 2. Two adjacent air supply branch pipes 2 are connected in the following manner: the right end of the branch pipe main body 210 of the previous air supply branch pipe 2 is thread - connected to the left end of the branch pipe main body 210 of the next air supply branch pipe 2. In addition, the air supply branch pipe 2 located at the end (the left end in this embodiment) is thread - connected to the air supply main pipe 1. And the branch pipe sub - pipe 220 of each air supply branch pipe 2 is thread - connected to the top end of the air delivery pipe 8.

[0042] Combined with Figure 5 As shown, a blocking plate 810 is integrally formed inside the air delivery pipe 8. The side wall of the air delivery pipe 8 is provided with a first ventilation hole 9 and a second ventilation hole 10 that communicate with the inside of the second housing 420. The blocking plate 810 is located between the first ventilation hole 9 and the second ventilation hole 10. The electric valve 7 can seal the second ventilation hole 10, and the electric valve 7 is controlled by the chip 5. Specifically, combined with Figure 6 and Figure 7 As shown, a first threaded through - hole is provided on the front side wall of the second housing 420, and a through - hole 11 opposite to the first threaded through - hole is provided on the rear side wall of the first housing 410; the electric valve 7 is electrically connected with an electrical connector 12 through a wire. The electrical connector 12 is thread - connected in the first threaded through - hole, and the electrical connector 12 can extend into the through - hole 11. The electrical connector 12 is electrically connected in the electrical circuit of the chip 5 through a wire; a sealing washer is sleeved on the electrical connector 12. When the electrical connector 12 is thread - connected in the first threaded through - hole, the sealing washer abuts against the inner side wall of the second housing 420, improving the sealing performance at the first threaded through - hole. A manual valve 13 is installed on the air delivery pipe 8, and the manual valve 13 is higher than the first ventilation hole 9. The bottom end of the air delivery pipe 8 is connected to the intake pipe 310 of the gas meter 3.

[0043] The front side wall of the first housing 410 is detachably connected to the first housing 410. Specifically, combined with Figure 8As shown, on both the left and right sides of the front sidewall of the first housing 410, two cards 411 are integrally formed. On both the left and right sidewalls of the first housing 410, two card slots 412 are provided for the cards 411 to be inserted into. On the top and bottom of the front sidewall of the first housing 410, recessed portions 413 are provided. During installation, press the front sidewall of the first housing 410 onto the first housing 410 and apply force to make the cards 411 snap into the corresponding card slots 412, then the front sidewall of the first housing 410 can be installed on the first housing 410. During disassembly, use a tool such as a thin plate to insert into the recessed portion 413 on the front sidewall of the first housing 410 and pry open the front sidewall of the first housing 410.

[0044] The right sidewall of the second housing 420 is detachably connected to the second housing 420. Specifically, as shown in Figure 3 and Figure 5 As shown, on the second housing 420, an ear plate 14 is integrally formed. The ear plate 14 is arranged around the upper, lower, front and rear sidewalls of the second housing 420. The ear plate 14 is provided with a number of second threaded through holes 15. On the right sidewall of the second housing 420, a number of mounting holes 16 corresponding to the second threaded through holes 15 are provided. In this embodiment, the number of the second threaded through holes 15 is four, and the four second threaded through holes 15 are located at the four corners of the ear plate 14. Each second threaded through hole 15 is threadedly connected with a screw. In this embodiment, the screw is an anti-theft screw 17. As shown in Figure 9 As shown, the anti-theft screw 17 includes a head 171 and a rod portion. The head 171 is provided with a hexagonal star groove 1711, and a cylinder 1712 is integrally formed on the bottom wall of the hexagonal star groove 1711. On the right end faces of the upper, lower, front and rear sidewalls of the second housing 420, mounting grooves are provided, and sealing rings are installed in the mounting grooves to ensure the sealing performance of the second housing 420.

[0045] The specific implementation process is as follows: The gas flows from the main gas supply pipeline 1 into the main body 210 of the branch pipeline 2 of the branch gas supply pipeline 2, and then flows into the gas pipeline 8 through the branch pipeline 220. Since the gas pipeline 8 is designed with a first ventilation hole 9 and a second ventilation hole 10 that communicate with the inside of the second housing 420, and the blocking plate 810 blocks the gas pipeline 8, therefore, the gas cannot directly enter the inlet pipe 310 of the gas meter 3 through the gas pipeline 8, but flows into the inlet pipe 310 of the gas meter 3 in the following way: gas pipeline 8 → first ventilation hole 9 → second housing 420 → second ventilation hole 10 → gas pipeline 8 → inlet pipe 310 of the gas meter 3, thus realizing the intake of gas.

[0046] When a fault occurs, such as the pipe at the gas stove falling off or the gas pipe in the user's home (the pipe from the outlet pipe 320 of the gas meter 3 to the middle of the gas stove) is damaged and leaking, the flow sensor monitors the gas flow in the outlet pipe 320 of the gas meter 3 in real time. Therefore, when the gas has been flowing in the outlet pipe 320, resulting in abnormal gas flow data, the chip 5 obtains the abnormal data from the flow sensor, and the chip 5 immediately controls the electric valve 7 to energize and work. The electric valve 7 blocks and seals the second vent 10, cuts off the gas intake, and automatically stops the gas intake in an unmanned environment to avoid continuous gas leakage, thereby avoiding the occurrence of safety accidents.

[0047] When the gas meter 3 needs to be replaced, since the shell 4 is separated from the gas meter 3, the shell 4 and the components inside the shell 4 can be retained when the gas meter 3 is replaced, avoiding replacing the shell 4 and the components inside the shell 4 together, thereby avoiding waste of resources and reducing replacement costs for gas companies and users.

[0048] In addition, in this embodiment, since the chip 5 is installed in the first housing 410 and the electric valve 7 is installed in the second housing 420, when the first housing 410 is opened to inspect the chip 5, the second housing 420 will not be affected, that is, the first housing 410 can be opened to inspect the components in the first housing 410 without closing the gas pipe 8 through the manual valve 13, which is convenient for operation. In addition, in this embodiment, due to the special structure of the head 171 of the anti-theft screw 17, a specific tool is required to rotate the anti-theft screw 17 to remove the right side wall of the second housing 420, thereby exposing the internal space of the second housing 420. Therefore, non-staff cannot normally remove the right side wall of the second housing 420, thereby avoiding the loss of the electric valve 7 and preventing the electric valve 7 from being stolen.

[0049] Finally, in this embodiment, two adjacent gas supply branch pipes 2 are threadedly connected together to form a gas supply pipe. Compared with using a tee pipe and a straight pipe to connect together to form a gas supply pipe, this embodiment reduces the connection points between the pipes, which not only reduces the installation steps for the staff, but also reduces the connection points of the gas supply pipes, thereby reducing the possibility of gas leakage from the pipe connection points and improving the safety of gas supply.

[0050] Embodiment 2

[0051] The difference between this embodiment and the first embodiment is that: Figure 10 and Figure 11 As shown, the first shell 410 and the second shell 420 are detachably connected, and the front side wall of the second shell 420 is integrally formed with two parallel slide rails 18. In this embodiment, the slide rail 18 is horizontally arranged, and the rear side wall of the first shell 410 is integrally formed with a slide rail 19 for the slide rail 18 to slide, and the number of the slide rails 19 is two.

[0052] In this embodiment, the slide rail 18 is slidably connected within the slideway 19. When the electrical connector 12 is threadedly connected within the first threaded through hole, the electrical connector 12 extends into the through hole 11, and the slide rail 18 cannot slide along the slideway 19, thereby fixing the first housing 410 and the second housing 420 and preventing relative slippage between the first housing 410 and the second housing 420. Additionally, a specific tool is required to remove the right side wall of the second housing 420. Therefore, non-staff members cannot normally separate the first housing 410 and the second housing 420, enhancing the safety of the housing 4.

[0053] Furthermore, the first housing 410 and the second housing 420 are detachably connected. Thus, when the first housing 410 or the second housing 420 is damaged, the damaged first housing 410 or second housing 420 can be replaced specifically without having to replace the entire housing 4, reducing the maintenance cost. When replacing the first housing 410 or the second housing 420, after removing the right side wall of the second housing 420, rotate the electrical connector 12 and remove the electrical connector 12, then the first housing 410 can be slid to separate the first housing 410 from the second housing 420, and the operation is simple and convenient.

[0054] Embodiment Three

[0055] The difference between this embodiment and Embodiment Two lies in: As shown in combination with Figure 12 and Figure 13 , within the first housing 410, there are provided a chip 5 mounting structure and a battery 6 mounting structure. The chip 5 mounting structure includes two sets of clamping components arranged oppositely. Each set of clamping components includes two clamping plates 20. The two clamping plates 20 located above are integrally formed on the inner surface of the upper side wall of the first housing 410 and form an upper limiting groove with the upper side wall of the first housing 410. The two clamping plates 20 located below are integrally formed on the inner surface of the lower side wall of the first housing 410 and form a lower limiting groove with the lower side wall of the first housing 410.

[0056] The battery 6 mounting structure includes a baffle 21, a plurality of arc-shaped support plates 22, and an arc-shaped pressing plate 23. The baffle 21 and the arc-shaped support plates 22 are both integrally formed on the inner surface of the rear side wall of the first housing 410, and the arc-shaped pressing plate 23 is integrally formed on the inner surface of the front side wall of the first housing 410. In this embodiment, the number of arc-shaped support plates 22 is three, and the number of arc-shaped pressing plates 23 is two.

[0057] In this embodiment, the chip 5 mounting structure is used to mount the chip 5, and the battery 6 mounting structure is used to mount the battery 6. Specifically, after removing the front side wall of the first housing 410, place the battery 6 on the arc-shaped support plate 22, and insert the chip 5 into the two clip assemblies, so that the top end of the chip 5 is located in the upper limit groove and the bottom end of the chip 5 is located in the lower limit groove, thus realizing the fixation of the chip 5. Then, electrically connect the electrical connector 12 to the electrical circuit of the chip 5 through a wire, and electrically connect the battery 6 to the electrical circuit of the chip 5 through a wire. Finally, press and install the front side wall of the first housing 410 on the first housing 410, and apply force to make the card 411 on the front side wall of the first housing 410 snap into the card slot 412, realizing the installation of the front side wall of the first housing 410.

[0058] Embodiment Four

[0059] The difference between this embodiment and Embodiment Three is that the control unit further includes a network communication module. As shown in Figure 14 , the chip 5 is used to obtain the gas consumption data monitored by the flow sensor, and the chip 5 can control the electric valve 7 to work according to the gas consumption data. The chip 5 is used to send the gas consumption data monitored by the flow sensor to the cloud platform through the network communication module. The chip 5 is used to receive the instruction sent by the cloud platform through the network communication module, and the chip 5 can control the electric valve 7 to work according to the instruction. The network communication module can adopt one of Wi-Fi module, Bluetooth module, NB-IOT or ZigBee self-organizing network. In this embodiment, the network communication module adopts NB-IOT.

[0060] In this embodiment, the flow sensor monitors the gas consumption data of the user in real time. After the chip 5 obtains the gas consumption data, it sends the data to the cloud platform through the network communication module, so as to store the gas consumption data of the user on the cloud platform for the gas company to calculate the gas fee of the user, eliminating the need for on-site meter reading and saving the labor cost and operating cost of the gas company. Moreover, the cloud platform can send an instruction to the chip 5 through the network communication module. After the chip 5 receives the instruction through the network communication module, it controls the electric valve 7 to be energized and work, and the electric valve 7 blocks the second ventilation hole 10, thus realizing remote control of the gas to stop entering.

[0061] In addition, the flow sensor transmits the monitored gas consumption data to the chip 5. The chip 5 judges whether the gas consumption data is abnormal. If the gas consumption data is abnormal, the chip 5 controls the electric valve 7 to be energized and work, and the electric valve 7 blocks the second ventilation hole 10 to stop the gas from entering, as much as possible avoiding the occurrence of gas accidents.

[0062] In summary, the present invention can not only achieve the security function to avoid accidents such as continuous gas leakage, but also realize the cloud platform billing function to avoid on-site meter reading, saving the labor cost and operating cost of the gas company, thereby realizing the intelligent and safe management of users' gas use by the gas company.

[0063] The above are only embodiments of the present invention, and specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can still be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application shall be subject to the content of its claims, and the specific implementation manners and the like recorded in the specification can be used to interpret the content of the claims.
