Description

Technical Field

[0001] This invention relates to the field of emergency water supply technology for buildings and communities, and in particular to a disinfection method and a water supply method for an emergency water supply system for buildings and communities. Background Technology

[0002] Urban water supply security is crucial to the national water security strategy and the daily lives of residents. In the event of sudden extreme disasters such as earthquakes and floods, urban water supply systems face severe challenges, and some areas may lose their automatic water supply function. Buildings and residential communities, as the last mile of urban water supply, are responsible for ensuring the basic water needs of urban residents. The water supply system of buildings and communities includes outdoor water supply network systems and indoor water supply network systems, while the secondary water supply pump stations connecting the two serve to boost the pressure and improve the efficiency of the indoor water supply system.

[0003] In extreme disasters, when municipal water supply systems fail, emergency water supply systems become crucial for ensuring the normal operation of building and community water supply systems. Currently, many buildings and communities in China, in addition to their conventional water supply systems, lack a dedicated emergency water supply system that connects the community's conventional water supply system with the emergency water source. In the event of a sudden extreme disaster and damage to the conventional water supply system, an emergency water supply system is urgently needed to guarantee the daily water needs of community residents.

[0004] Currently, there are many types of mobile emergency water supply equipment on the market, such as emergency water supply vehicles and emergency water supply pumps. These facilities alleviate the pressure on cities caused by temporary water demand. However, this type of water supply relies on residents bringing their own water storage buckets to collect water, which has limited capacity and low water supply efficiency.

[0005] Therefore, an emergency water supply system needs to be provided that can be constructed in parallel with the indoor water supply network. However, in non-emergency situations, the downstream pipeline modules, which are standby facilities in the emergency water supply system, will be idle for a long time and may be subject to contamination.

[0006] Therefore, there is an urgent need to provide a disinfection method for emergency water supply systems in buildings and communities. Summary of the Invention

[0007] Based on the above analysis, the embodiments of the present invention aim to provide a disinfection method and a water supply method for an emergency water supply system in buildings and communities, in order to solve the problem in the prior art that the downstream pipeline module, which is a standby facility in the emergency water supply system, will be idle for a long time and will be contaminated in non-emergency situations.

[0008] The objective of this invention is mainly achieved through the following technical solutions:

[0009] A disinfection method for an emergency water supply system in buildings and communities, utilizing an emergency water supply system, includes the following steps:

[0010] A. Prepare disinfectant solution;

[0011] B. Inject disinfectant into the emergency water supply system;

[0012] C. Drain the disinfectant solution;

[0013] D. Complete disinfection.

[0014] Furthermore, the disinfectant is a potassium permanganate disinfectant with a concentration of 0.03%-0.10% by mass.

[0015] Furthermore, in step B, injecting disinfectant into the emergency water supply system, the following steps are included: closing the first gate valve.

[0016] Furthermore, step B, injecting disinfectant into the emergency water supply system, also includes: closing the shut-off valve.

[0017] Furthermore, step B, injecting disinfectant into the emergency water supply system, also includes filling the downstream pipeline with disinfectant through the downstream interface assembly.

[0018] Furthermore, step B, injecting disinfectant into the emergency water supply system, also includes: soaking for 30 minutes for disinfection.

[0019] Furthermore, step C, discharging the disinfectant, includes: opening the shut-off valve, and discharging the disinfectant from the downstream pipe through the drain pipe.

[0020] Furthermore, the slope of the downstream pipeline is 1%.

[0021] Furthermore, before step D, which involves completing disinfection, the procedure also includes rinsing the emergency water supply system.

[0022] A method for emergency water supply in buildings and communities, including a disinfection method, and further including the following steps:

[0023] Connect the emergency water supply system to the indoor water supply network;

[0024] Emergency water supply initiated;

[0025] Emergency water supply completed.

[0026] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0027] (1) The disinfection method provided by the present invention utilizes the disinfectant tank of the emergency water supply system and the prepared chlorine-containing disinfectant solution to disinfect the pipeline of the emergency water supply system before emergency water supply, thereby ensuring the safety of emergency water supply.

[0028] (2) After the upstream interface assembly and the downstream interface assembly of the water supply interface of the present invention are connected in a forward rotation, the locking teeth can be radially locked into the limiting groove to prevent the upstream interface assembly from rotating in the reverse direction, thereby causing the locking claws to disengage from the locking groove and causing the upstream interface assembly and the downstream interface assembly to separate; moreover, the locking teeth can also restrict the upstream flange from disengaging from the downstream flange in the axial direction, ensuring a tight connection between the upstream interface assembly and the downstream interface assembly.

[0029] (3) The flange end cap of the water supply interface of the present invention is connected to the downstream flange by screws or threads. The downstream flange and the flange end cap make the locking teeth only rotate radially and cannot move axially, ensuring that the upstream flange will not axially separate from the downstream flange after the locking teeth are inserted into the limiting groove.

[0030] (4) When the buckle of the water supply interface of the present invention is an elastic buckle, the buckle can be engaged with the protrusion, thereby connecting the first upright plate and the second upright plate. When the buckle is moved, the buckle can be disconnected from the protrusion, thereby opening the top cover and the bottom support.

[0031] (5) In the non-emergency connection state, the two sets of sealing units of the protective box module of the water supply interface of the present invention can seal the gap, and the protective box module can provide complete protection for the downstream interface assembly; in the emergency connection state, the sealing unit can leave the gap open, and the protective box module can provide complete protection for the entire interface module.

[0088] Step 7: Disassemble the emergency water supply system, including the following steps:

[0089] Step 71: Lock-protection box module 3;

[0090] Preferably, by flipping the latch 341, the latch 341 is disconnected from the protrusion 342, opening the upper cover 32 and the bottom support 33, thereby unlocking the protective box module 3;

[0091] Step 72: Disconnect the upstream interface assembly 21 and the downstream interface assembly 22;

[0092] Preferably, the lever 2262 is reversed, causing the wheel rim 2261 to rotate, which in turn causes the locking teeth 225 to rotate around the first pin, thereby causing the locking part 2251 to radially disengage from the limiting groove 215; the upstream interface assembly 21 is rotated in the opposite direction, the pawl 213 disengages from the protrusion, and the upstream interface assembly 21 is pulled out from the downstream interface assembly 22; the lever 2262 is released, the lever spring 227 causes the dial wheel 226 to rotate in the forward direction, the lever 2262 encounters the stop protrusion 228, the dial wheel 226 stops rotating, and the locking teeth 225 are in the locked position;

[0095] Step 8: Complete emergency water supply

[0096] After closing the shut-off valve 52 and sealing the drain module 5 and downstream pipeline module 4, the emergency water supply is completed. Downstream pipeline module 4 then enters its normal standby state.

[0097] Example 3

[0098] Another specific embodiment of the present invention, such as Figure 3As shown, an emergency water supply system for buildings and communities (hereinafter referred to as the emergency water supply system) is disclosed to implement the methods of Embodiment 1 and Embodiment 2. The emergency water supply system includes an emergency water supply device 1, an interface module 2, and a downstream module 4. The downstream pipeline module 4 is connected to the indoor water supply network system 100. In an emergency, the emergency water supply device 1 can connect to the downstream pipeline module 4 through the interface module 2 to provide emergency water supply to the indoor water supply network system 100. When a sudden natural disaster occurs in the city and the municipal water supply system or the conventional water supply system of buildings and communities is damaged, the emergency water supply system of this embodiment can temporarily guarantee the water supply of buildings and communities, so that residents can obtain emergency tap water supply without leaving their homes and maintain normal life in buildings and communities.

The upstream pipe 14 is connected to the water pump 12, and the water pump 12 can selectively output liquid from the water tank 11 to the upstream pipe 14. The pressure gauge 13 is installed on the upstream pipe 14 to display the liquid pressure within the upstream pipe 14.

[0102] Preferably, the upstream pipe 14 is a PVC-lined rubber hose, which is flexible and easy to store and deploy.

[0103] Preferably, the downstream pipeline module 4 includes a downstream pipeline 41, a first gate valve 42, a check valve 43, and a second gate valve 44. From the interface module 2 towards the indoor water supply network system 100, the first gate valve 42, check valve 43, and second gate valve 44 are sequentially installed on the downstream pipeline 41. The downstream pipeline module 4, as a permanent component of the emergency water supply system in this embodiment, is connected to the indoor water supply network system 100. However, it is normally disconnected from the indoor water supply network system 100, and is only opened to supply water to the indoor water supply network system 100 in emergencies.

[0104] Preferably, the downstream pipe 41 is a stainless steel pipe, including a buried section, the outer wall of which is coated with plastic for corrosion protection. The downstream pipe 41 is buried at a slope of 1% to facilitate the drainage of residual liquid in the downstream pipe 41 by gravity.

[0105] Preferably, the first gate valve 42 is used to close the downstream pipeline 41 and prevent disinfectant from entering the check valve 43 when the downstream pipeline 41 is flushed and disinfected.

[0106] Preferably, the check valve 43 prevents water from flowing back from the indoor water supply network system 100 to the emergency water supply equipment 1.

[0107] Preferably, one end of the second gate valve 44 is connected to the indoor water supply network system 100, and is normally closed, but is opened in an emergency to isolate or open the system.

The drain module 5 includes a drain outlet 51, a shut-off valve 52, and a drain pipe 53. The drain pipe 53 is connected to the downstream pipe 41 through the drain outlet 51, and the shut-off valve 52 is installed on the drain pipe 53.

[0109] Preferably, the drain outlet 51 is used to discharge wastewater from the downstream pipe 41. The shut-off valve 52 prevents exhaust gas from the drain outlet from entering the downstream module 4.

[0110] Preferably, the drain pipe 53 is connected to a rainwater inspection well (not shown in the figure) and is capable of conveying wastewater from the downstream pipe 41. The drain pipe 53 is made of PVC material.

[0111] Preferably, such as Figure 4 As shown, interface module 2 includes an upstream interface assembly 21 and a downstream interface assembly 22. The upstream interface assembly 21 is connected to the upstream pipe 15, and the downstream interface assembly 22 is connected to the downstream pipe 41. The upstream interface assembly 21 and the downstream interface assembly 22 can be docked to connect the emergency water supply equipment 1 to the downstream pipe module 4 so as to provide emergency water supply to the indoor water supply network system 100.

[0112] Preferably, such as Figure 5 and Figure 6 As shown, both the upstream interface assembly 21 and the downstream interface assembly 22 are cylindrical structures, including a central shaft. The upstream interface assembly 21 includes an upstream pipe connector 211, an upstream flange 212, and a clamp 213, which are respectively located at both ends of the upstream flange 212. The upstream pipe connector 211 is connected to the upstream pipe 15. This embodiment does not limit the connection method between the upstream pipe connector 211 and the upstream pipe 15. The longitudinal section of the clamp 213 is L-shaped, used for connection with the downstream interface assembly 22.

[0113] Preferably, the downstream interface assembly 22 includes a downstream pipe connector 221, a downstream flange 222, and a slot 223, with the downstream pipe connector 221 and the slot 223 respectively disposed at both ends of the downstream flange 222. The downstream pipe connector 221 is used to connect to the downstream pipe 41. This embodiment does not limit the connection method between the downstream pipe connector 221 and the downstream pipe 41. The longitudinal section of the downstream flange 222 is concave, including a bottom surface and an inner surface. The inner surface is cylindrical, allowing the upstream flange 212 to be inserted into the downstream flange 222 and connected to the bottom surface. A slot 223 is provided on the bottom surface of the downstream flange 222. A protrusion is provided on the opening of the slot 223, forming a hollow portion with the slot 223. A claw 213 can be inserted into the slot 223. When the upstream interface assembly 21 is rotated, the claw 213 can be inserted into the hollow portion and locked by the protrusion, thereby connecting the upstream interface assembly 21 and the downstream interface assembly 22 and preventing the upstream interface assembly 21 and the downstream interface assembly 22 from separating in the central axis direction. The above rotation direction is forward, and the reverse is backward.

[0114] Preferably, there are multiple and equal numbers of claws 213 and slots 223, which are evenly distributed around the central axis on the circumference of the upstream flange 212 and the downstream flange 222. Preferably, there are 2-4 claws 213 and slots 223 to further ensure the connection between the upstream interface assembly 21 and the downstream interface assembly 22.

[0115] Preferably, the upstream interface assembly 21 further includes an upstream pipe port 214, and the downstream interface assembly 22 further includes a downstream pipe port 224. The upstream pipe port 214 can be inserted into the downstream pipe port 224 for connection, and water can flow from the emergency water supply equipment 1 into the indoor water supply network system 100 through the upstream pipe port 214 and the downstream pipe port 224. The upstream pipe port 214 and the downstream pipe port 224 are coaxial to ensure accurate docking when the upstream interface assembly 21 and the downstream interface assembly 22 are connected.

[0116] Preferably, the outer surface of the upstream port 214 and the inner surface of the downstream port 224 are the same and are gradient surfaces. The outer surface of the upstream port 214 and the inner surface of the downstream port 224 are conical, arc-shaped or stepped, which facilitates the guidance when the upstream port 214 is inserted into the downstream port 224.

[0117] Preferably, a first sealing ring (not shown in the figure) is provided on the downstream port 224. The inner diameter of the first sealing ring is smaller than the outer diameter of the upstream port 214. When the upstream port 214 is inserted into the downstream port 224, the first sealing ring ensures a seal when the interface module 2 of this embodiment is connected.

[0118] Preferably, a second sealing ring (not shown in the figure) is provided on the downstream flange 222, and the second sealing ring is disposed on the bottom surface. The second sealing ring can be connected to the end face of one end of the upstream flange 212, and the second sealing ring ensures a seal when the upstream pipe port 214 is inserted into the downstream pipe port 224 during the connection of the interface module 2 in this embodiment.

[0119] Preferably, the upstream interface assembly 21 further includes a limiting groove 215, which is disposed on the upstream flange 212 and is a recessed area on the outer wall of the upstream flange 212; the downstream interface assembly 22 further includes a retaining tooth 225, which is disposed on the downstream flange 222. After the upstream interface assembly 21 and the downstream interface assembly 22 are connected by forward rotation, the retaining tooth 225 can be radially engaged with the limiting groove 215 to prevent the upstream interface assembly 21 from rotating in the reverse direction, thereby preventing the retaining claw 213 from disengaging from the retaining groove 223 and causing the upstream interface assembly 21 to disengage from the downstream interface assembly 22. At this time, the retaining tooth 225 is in the locked position; otherwise, the retaining tooth 225 is in the unlocked position. Moreover, the retaining tooth 225 can also restrict the upstream flange 212 from disengaging from the downstream flange 222 in the axial direction, ensuring a tight connection between the upstream interface assembly 21 and the downstream interface assembly 22.

[0120] Preferably, such as Figure 7 As shown, the downstream interface assembly 22 also includes a dial 226, which is mounted on the downstream flange 222. The dial 226 includes a rim 2261 and a lever 2262. The lever 2262 is mounted on the rim 2261, which has a circular structure and can rotate on the downstream flange 222 about its central axis. Moving the lever 2262 causes the rim 2261 to rotate.

[0121] Preferably, the locking tooth 225 includes a locking part 2251, a rotating part 2252, and a linkage part 2253. One end of the locking tooth 225 is the locking part 2251, which can be inserted into the limiting groove 215 to lock the upstream flange 212 and prevent the upstream flange 212 from rotating in the opposite direction. The other end of the locking tooth 225 is the rotating part 2252, which is rotatably connected to the downstream flange 222 through a first pin (not shown in the figure). The locking tooth 225 can rotate around the first pin, so that the locking part 2251 can be radially inserted into or disengaged from the limiting groove 215. The linkage part 2253 is disposed on the rotating part 2252 and is rotatably connected to the wheel rim 2261 through a second pin (not shown in the figure). The wheel rim 2261 can drive the locking tooth 225 to rotate around the first pin.

[0122] Preferably, the downstream interface assembly 22 further includes a lever spring 227 and a stop protrusion 228. One end of the protrusion 28 and one end of the lever spring 227 are connected to the downstream flange 222, and the other end of the lever spring 227 is connected to the lever 2262. The lever spring 227 keeps the dial wheel 226 rotating in the forward direction, and the stop protrusion 228 prevents the dial wheel 226 from rotating in the forward direction. When the upstream interface assembly 21 and the downstream interface assembly 22 are not connected, the lever spring 227 and the stop protrusion 228 keep the locking tooth 225 in the locked position through the dial wheel 226. When the lever 2262 is moved in the opposite direction, the wheel rim 2261 rotates in the reverse direction, which drives the locking tooth 225 to rotate radially, ultimately putting the locking tooth 225 in the unlocked position.

[0123] Preferably, there are multiple and equal numbers of retaining teeth 225 and limiting grooves 215, which are evenly distributed around the central axis on the circumference of the downstream flange 222 and the upstream flange 212. Preferably, the number of retaining teeth 225 and limiting grooves 215 is 4-8, which further prevents the upstream interface assembly 21 from rotating in the opposite direction and restricts the upstream flange 212 from disengaging from the downstream flange 222 in the axial direction, ensuring a tight connection between the upstream interface assembly 21 and the downstream interface assembly 22.

[0124] Preferably, such as Figure 5 As shown, the outer surface of one end of the upstream flange 212 is a conical surface. During the process of inserting the upstream interface assembly 21 into the downstream interface assembly 22, the conical surface of one end of the upstream flange 212 can gradually push the retaining teeth 225 radially open, ensuring that the upstream flange 212 can be smoothly inserted into the downstream flange 222.

[0125] Preferably, such as Figure 6 As shown, in order to prevent the retaining tooth 225 from axially disengaging from the downstream flange 222, the downstream interface assembly 22 also includes a flange end cover 229. The flange end cover 229 is connected to the downstream flange 222 by screws or threads. The downstream flange 222 and the flange end cover 229 ensure that the retaining tooth 225 can only rotate radially and cannot move axially, thus ensuring that after the retaining tooth 225 is inserted into the limiting groove 215, the upstream flange 212 will not axially disengage from the downstream flange 222.

[0126] Preferably, the emergency water supply system of this embodiment further includes a protective box module 3, which is connected to the interface module 2, and the protective box module 3 provides airtight protection for the interface module 2.

[0127] Preferably, such as Figure 8As shown, the protective box module 3 is a box structure, including a main frame 31, a top cover 32, and a bottom support 33. The main frame 31 is connected to the downstream pipe connection 221, and both the top cover 32 and the bottom support 33 are connected to the main frame 31. The main frame 31 has a U-shaped structure and includes three side plates. In the non-emergency connection state, that is, when only the downstream interface assembly 22 is inside the protective box module 3, the protective box module 3 protects the downstream interface assembly 22.

[0128] Preferably, such as Figure 9 As shown, the upper cover 32 includes a cover plate 321 and a first upright plate 322. The cover plate 321 is hinged to the main frame 31, and the first upright plate 322 is disposed on the cover plate 321. The upper cover 32 can rotate around the hinge to open the protective box module 3; the upper cover 32 can also rotate around the hinge to close the protective box module 3.

[0129] Preferably, the upper cover 32 further includes a waterproof edge 323, which is disposed at both ends of the cover plate 321 and the first upright plate 322. The waterproof edge 323 can be connected to the main frame 31 to seal the main frame 31 and prevent rainwater from entering the main frame 31.

[0130] Preferably, the base 33 includes a base plate (not shown) and a second upright plate 332. The base plate is hinged to the main frame 31, and the second upright plate 332 is mounted on the base plate. The base plate can rotate around the hinge to open the protective box module 3; the base plate can also rotate around the hinge to close the protective box module 3. The first upright plate 322 can be connected to the second upright plate 332 to provide long-term protection for the downstream interface assembly 22.

[0131] Preferably, the protective box module 3 further includes a connecting lock 34, which includes a latch 341 and a protrusion 342. The latch 341 is disposed on the first upright plate 322, and the protrusion 342 is disposed on the second upright plate 332. The latch 341 is an elastic latch, which can engage with the protrusion 342 to connect the first upright plate 322 and the second upright plate 332. By moving the latch 341, the latch 341 can be disconnected from the protrusion 342, thereby opening the upper cover 32 and the base 33.

[0132] Preferably, the first upright plate 322 and the second upright plate 332 are provided with notches, so that when the upstream interface assembly 21 is connected to the downstream interface assembly 22, the first upright plate 322 and the second upright plate 332 can be connected, and the upstream pipe connection 211 can pass through the notches. This ensures that the entire interface module 2 can be completely protected by the protective box module 3 in an emergency connection state.

[0133] However, in a non-emergency connection state, that is, when only the downstream interface assembly 22 is inside the protective box module 3, the presence of the gap creates a vulnerability in the protective box module 3. Preferably, the protective box module 3 further includes two sets of sealing units 35, which are respectively disposed on the first upright plate 322 and the second upright plate 332. In a non-emergency connection state, the two sets of sealing units 35 can close the gap, and the protective box module 3 can provide complete protection for the downstream interface assembly 22; in an emergency connection state, the sealing units 35 can open the gap, and the protective box module 3 can provide complete protection for the entire interface module 2.

[0134] Preferably, such as Figure 10 As shown, the closing unit 35 includes a movable plate 351, a slide 352, and a closing spring 353. The slide 352 is disposed on the first upright plate 322, and the movable plate 351 is disposed on the slide 352. The movable plate 351 can slide on the slide 352, thereby opening or closing the opening. One end of the closing spring 353 is connected to the movable plate 351, and the other end of the closing spring 353 is connected to the slide 352 or the first upright plate 322. The closing spring 353 keeps the movable plate 351 in a closed state over the opening.

[0135] Compared to existing technologies, in this embodiment, in emergency situations, the emergency water supply equipment 1 can connect to the downstream pipeline module 4 through the interface module 2 to provide emergency water supply to the indoor water supply network system 100. When a sudden natural disaster occurs in the city and the municipal water supply system or the conventional water supply system of the building and community is damaged, the emergency water supply system of this embodiment can temporarily guarantee the water supply of the building and community, so that residents can obtain emergency tap water supply without leaving home and maintain the normal life of the building and community.

[0136] The emergency water supply system of this embodiment is applicable to both new and existing buildings. This emergency water supply system can be designed, constructed, and inspected simultaneously with the building; existing buildings can be renovated by referring to this emergency water supply system and adding an emergency water supply system.

[0137] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
