Description

Technical Field

[0001] This application relates to the technical field of water distribution equipment, and in particular to a ground-mounted double-layer grid water distributor. Background Technology

[0002] In a water storage system, the water storage tank is an energy-saving device for storing and releasing cold and heat. The ground-mounted double-layer grid water distributor, as a key component for distributing fluids within the tank, is an energy-saving heat exchanger or cold exchanger. Its water distribution uniformity and pipeline cleanliness directly determine the storage efficiency and heat exchange effect of cold or heat within the tank.

[0003] During the operation of water storage tanks, trace impurities carried by the water flow easily adhere to the inner wall of the water distributor pipes. If not cleaned in time, these stubborn deposits will reduce the flow area, disrupt the stability of the water flow, and further exacerbate the problem of uneven water distribution. At the same time, the efficient utilization of cold or heat in the tank depends on the formation of a stable and orderly flow field within the tank. This places extremely high demands on the uniform distribution performance of the water distributor. Uneven water distribution can lead to short circuits in cold or heat within the tank, or localized energy accumulation, significantly reducing the system's energy utilization efficiency. Existing ground-mounted double-layer bar grid water distributors typically use a main water supply pipe to divert water to a secondary water supply pipe, and then distribute the water through a uniform outflow component, working in conjunction with a double-layer bar grid to achieve initial flow stabilization and impurity interception. However, these types of water distributors generally lack a targeted self-cleaning structure for the pipes, making it difficult to promptly treat deposits on the inner wall.

[0004] Regarding the aforementioned technologies, the inventors believe that there are drawbacks such as difficulty in achieving uniform water flow distribution across the entire tank cross-section and inability to promptly clean impurities adhering to the pipeline to maintain stable water distribution. Summary of the Invention

[0005] To address the aforementioned technical problems, this application provides a ground-mounted double-layer grid water distributor.

[0006] This application provides a ground-mounted double-layer grid water distributor, which adopts the following technical solution: A ground-mounted double-layer grid water distributor includes an energy-saving tank. Gravity flow grids are respectively installed on the upper and lower parts of the energy-saving tank. The two sets of gravity flow grids divide the energy-saving tank into a first uniform distribution zone, a transition zone, and a second uniform distribution zone from top to bottom. Water distribution units are installed in both the first and second uniform distribution zones. Each water distribution unit includes a main water supply pipe, multiple sets of auxiliary water supply pipes, and multiple sets of uniformly distributed outflow components. The main water supply pipe is installed inside the energy-saving tank. One end of each of the multiple sets of auxiliary water supply pipes is uniformly connected to the main water supply pipe, and the uniformly distributed outflow components are connected to the other end of the auxiliary water supply pipes.

[0007] By adopting the above technical solution, the energy-saving tank is divided into two independent and uniformly distributed zones by a double-layer gravity flow grid. The water flow needs to pass through the dual effects of two-stage water distribution units and the grid. Compared with a single-layer water distribution structure, this can greatly avoid the concentrated impact of water flow on a certain area, and achieve all-round uniform diffusion of water flow across the cross-section of the energy-saving tank. This can reduce the thickness of the inclined temperature layer in energy storage scenarios or the uneven stress on the filter layer in water treatment scenarios, and weaken the direct impact of water flow on the bottom and internal structure of the energy-saving tank. This can prevent problems such as pitting and delamination of the media layer at the bottom of the energy-saving tank, maintain the stable structure of the filter media or other treatment media, ensure the stability of water treatment effect, and avoid fluctuations in effluent water quality due to media layer disorder. The water distribution unit adopts a main water supply pipe with multiple sets of evenly distributed auxiliary water supply pipes, and is further refined by uniformly distributed outflow components, allowing water to penetrate or flow out at a stable flow rate, improving the precision of water distribution.

[0008] Preferably, the auxiliary water supply pipe is provided with an adjustment structure, which includes a sliding plate, an installation pipe, a baffle assembly, and an installation plate; the installation pipe is fixedly installed inside the auxiliary water supply pipe and has multiple sets of water outlets; the baffle assembly is slidably installed in the lower part of the installation pipe; the sliding plate is slidably installed inside the installation pipe, and the bottom of the sliding plate abuts against the baffle assembly; the installation plate is fixedly installed inside the auxiliary water supply pipe, located below the installation pipe, and the edge portion of the installation plate is provided with multiple sets of control openings circumferentially.

[0009] By adopting the above technical solution, the regulating structure uses the combined action of flow rate and gravity to activate the baffle assembly, achieving precise flow control at the level of a single auxiliary water supply pipe. When the main water supply pipe branches into multiple auxiliary water supply pipes, the auxiliary water supply pipes closer to the inlet of the main water supply pipe have higher water pressure and correspondingly increased flow. The gravity generated by the water flow impacting the sliding plate increases accordingly, driving the baffle assembly to slide significantly and block the control opening on the mounting plate, thereby reducing the flow rate of that branch by reducing the flow area. Meanwhile, the auxiliary water supply pipes farther from the inlet have lower water pressure and smaller flow. The sliding plate has insufficient gravity, and the baffle assembly only moves slightly, maintaining a large opening in the control opening to ensure flow. This makes the outflow of water from all auxiliary water supply pipes more consistent, completely solving the problem of water grabbing at the near end and water shortage at the far end caused by differences in pipeline resistance in traditional water distributors, and ensuring uniform flow.

[0010] Preferably, the baffle assembly includes multiple sets of sliding blocks, a drive column, and an elastic ring; the drive column is slidably disposed within the secondary water supply pipe, and the top of the drive column abuts against the sliding plate; the sliding plate is slidably disposed on the mounting plate; one end of each sliding block has a mating inclined surface, and the multiple sets of sliding blocks are arranged circumferentially along the drive column, with the drive column abutting against the mating inclined surface; the elastic ring is sleeved on one end of the multiple sets of sliding blocks, and the elastic ring is used to keep the mating inclined surface of the multiple sets of sliding blocks abutting against the drive column; the other end of each sliding block is disposed on one side of the control opening.

[0011] By adopting the above technical solution, multiple sets of sliding baffles are arranged circumferentially along the drive column. With the design of the inclined surface, the longitudinal displacement of the drive column can be converted into the lateral synchronous displacement of the sliding baffles. When there is a slight change in the water flow rate, it will cause the sliding plate to move slightly, thereby pushing the drive column downward. The drive column squeezes the multiple sets of sliding baffles outward synchronously through the inclined surface, accurately blocking the corresponding control opening on the mounting plate. The coordinated action of multiple baffles can make the adjustment of the flow area more delicate, avoiding the problem of sudden changes in flow area caused by the adjustment of a single baffle. Even with small fluctuations in flow rate, precise flow control can be achieved through the slight displacement of the baffles, ensuring that the water flow out of the uniformly distributed component remains balanced. The elastic ring is always fitted on one end of the multiple sets of sliding baffles, continuously providing inward contraction force. As the flow rate decreases, the pressure of the sliding plate on the drive column weakens, and the contraction force of the elastic ring will quickly pull the multiple sets of sliding baffles inward to reset. The drive column also rises accordingly, and the opening of the control opening increases synchronously to adapt to the small flow rate requirement.

[0012] Preferably, the gravity flow grid is divided into a first partition and a second partition, with the second partition disposed on the side near the water distribution unit; the first partition has multiple sets of first through holes, and the second partition has multiple sets of second through holes; the number of first through holes is greater than the number of second through holes.

[0013] By adopting the above technical solution, compared with the first baffle with a large number of through holes, the design with fewer through holes in the second baffle will create a certain water flow resistance. When the water flows out from the water distribution unit, it first impacts the second baffle. The kinetic energy of the water flow will be effectively buffered and consumed by the baffle, and the flow velocity will be initially reduced. This prevents high-speed water flow from directly entering the transition zone or the next uniform distribution zone, and prevents water flow impact from causing water flow turbulence inside the energy-saving tank. It can also prevent water flow from scouring the filter media layer, causing the filter media to shift and stratify. At the same time, the uniformly distributed second through holes can disperse the concentrated water flow into multiple small water flows, allowing the water flow to form a uniform flow state.

[0014] Preferably, the uniformly distributed outflow assembly includes a main water distribution pipe, two sets of secondary water distribution pipes, multiple sets of equalizing pipes, and multiple sets of outlet pipes; the main water distribution pipe is connected in the middle to the other end of the secondary water supply pipe; the middle of one set of secondary water distribution pipes is connected to one end of the main water distribution pipe, and the middle of another set of secondary water distribution pipes is connected to the other end of the main water distribution pipe; both ends of the single set of secondary water distribution pipes are respectively connected to the middle of the two sets of equalizing pipes; the multiple sets of outlet pipes are arranged on both sides of the equalizing pipes.

[0015] By adopting the above technical solution, a multi-stage diversion path is formed, which can gradually eliminate the pressure difference and velocity difference of the water flow. The water flow is first diverted through the main diversion pipe to the secondary diversion pipes at both ends to avoid the attenuation of the water flow at the end caused by single-path delivery. Each set of secondary diversion pipes then divides the water flow to the equalization pipes at both ends to further refine the water flow distribution. Finally, the water is discharged through multiple sets of outlet pipes on both sides of the equalization pipe. This layered diversion method can avoid the problem of local water flow concentration or weak water flow. Even if the cross-section of the energy-saving tank is large, the flow rate and velocity of each outlet pipe can be kept consistent, ensuring that there are no dead corners when distributing water close to the ground. This meets the core uniform distribution requirements of the water distributor. Multiple sets of equalization pipes, together with the outlet pipes on both sides, can greatly increase the number and distribution density of water outlets, significantly improve the water distribution coverage efficiency, and also provide a uniform water flow basis for subsequent collaborative work with the double-layer grid.

[0016] Preferably, a buffer structure is provided at the connection between the flow equalization pipe and the outlet pipe. The buffer structure includes a first flow channel and a second flow channel, and the flow equalization pipe is connected to the outlet pipe through the first flow channel and the second flow channel.

[0017] By adopting the above technical solution, the first and second flow channels disperse the kinetic energy of the water flow, playing a significant role in buffering and dissipating energy, reducing the impact of water flow turbulence in the outlet pipe on the stability of the outlet water, and extending the service life of the flow equalization pipe and the outlet pipe; the dual-flow channel structure can compensate for the flow deviation that may occur when the single-flow channel is connected, allowing the water flow entering the outlet pipe to maintain a stable flow velocity, thereby ensuring that the water flow of all outlet pipes is highly consistent. Combined with the multi-stage diversion of the uniform flow distribution component, precise uniform distribution is achieved within the entire energy-saving tank range.

[0018] Preferably, the first flow channel and the second flow channel are provided with multiple sets of continuous turning sections; the extension directions of two adjacent sets of turning sections are arranged at a preset angle, and each set of turning sections is connected in sequence.

[0019] By adopting the above technical solution, when the water flows through the continuous turning section, the flow direction changes every time it passes through the turning section. During the turning process, the water will rub against the channel wall due to centrifugal force. At the same time, the angle difference between the turning sections will disrupt the inertial motion trajectory of the water, causing the kinetic energy of the water to be continuously consumed. This multi-stage energy dissipation method can significantly reduce the water flow velocity compared to a single-turn channel. During long-distance transportation or diversion, the water is prone to turbulent flow patterns such as turbulence and vortices, which can cause deviations in the flow rate of different outlet pipes connected to the same flow equalization pipe. Changing the water flow direction multiple times forces the water flow pattern to be regulated. By regulating the water flow through the turning section, the water flow state output from the two channels can be kept consistent, thereby ensuring that the water flow rate and velocity of all outlet pipes are highly uniform, further improving the uniformity of the entire water distribution system.

[0020] Preferably, a pressure tap is provided on the side of the water outlet pipe, and a drive plate is slidably mounted on the pressure tap; a clearance groove is provided inside the outlet of the water outlet pipe, and a one-way opening structure is provided in the clearance groove, the one-way opening structure including a trigger block, a trigger groove, a sliding block, a sliding cylinder, and a return spring; the trigger groove is located at the bottom of the clearance groove, and one end of the trigger block is slidably mounted in the trigger groove; the return spring is sleeved on the trigger block, one end of the return spring is fixedly mounted on the clearance groove, and the other end of the return spring is fixedly mounted on the other end of the trigger block; the sliding cylinder is located on the water outlet pipe below the pressure tap, one end of the sliding block is slidably mounted in the sliding cylinder, and the other end of the sliding block is fixedly mounted on one end of the drive plate; the trigger groove communicates with the sliding cylinder.

[0021] By adopting the above technical solution, the high pressure inside the tank after filling will cause water to flow back into the outlet pipe. The backflow of water will trigger the one-way opening structure, which in turn opens the drive plate. The negative pressure generated by the backflow can drive the water to rush into the pipe at high speed through the pressure tap. This high-speed water flow can form a strong flushing force, which can promptly remove impurities, scale, or media residues that have just adhered to the inner wall of the outlet pipe. The cleaning is automatically completed after each filling operation, reducing the problem of pipe narrowing and blockage caused by the accumulation of deposits from the source, and ensuring the long-term stable flow capacity of the outlet pipe. The reset spring and trigger block in the one-way opening structure work together to keep the drive plate closed when water flows into the energy-saving tank in the forward direction. This effectively prevents backflow of water in the tank during the normal filling phase. When filling stops and the pressure in the tank exceeds the pressure in the pipe, the structure can respond to the backflow in an orderly manner, preventing the backflow from directly impacting upstream components such as the main water distribution pipe and the flow equalization pipe. This prevents these components from being damaged by the impeller or loosening of the interface due to reverse pressure and water flow impact, and plays a protective role similar to a check valve, ensuring the safety of the entire uniform flow distribution assembly.

[0022] Preferably, a drain pipe is connected between the main water distribution pipes on the multiple sets of uniformly distributed outflow components, and a switch valve is provided at the outlet end of the drain pipe.

[0023] By adopting the above technical solution, the drain pipe connects all the main and branch water pipes of the evenly distributed outflow components into a unified sewage network. When the one-way opening structure triggers automatic flushing, the mixture of impurities and flushing fluid in each outlet pipe, equalization pipe, and secondary branch water pipe can be uniformly collected in the main branch water pipe and discharged centrally through the drain pipe. Compared with the method of discharging through each pipe individually when there is no drain pipe, this method achieves simultaneous sewage discharge of all components, significantly shortens the sewage discharge time, and avoids secondary blockage caused by residual mixture in the pipes.

[0024] Preferably, the water outlet pipe is provided with a water distribution head, the water distribution head includes a base plate and multiple sets of isolation plates, the multiple sets of isolation plates are evenly arranged on the base plate along the circumference of the water outlet pipe, and the water outlet pipe is arranged on the isolation plates.

[0025] By adopting the above technical solution, multiple sets of circumferentially uniform isolation plates can disperse the impact force of the water flow from the outlet pipe, allowing the water flow to spread in a stable state and preventing disturbance of the surrounding fluids to form turbulence; multiple sets of circumferentially uniform isolation plates divide the water flow from the outlet pipe into multiple uniform diversion channels, which can guide the water flow to spread evenly in all directions, avoiding the situation where the water flow concentrates on impacting a certain area, resulting in excessively strong local water flow and no water in other areas.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The regulating structure uses the combined action of flow rate and gravity to activate the baffle assembly, achieving precise flow control at the level of a single auxiliary water supply pipe. When the main water supply pipe branches into multiple auxiliary water supply pipes, the auxiliary water supply pipes closer to the inlet of the main water supply pipe have higher water pressure and a correspondingly increased flow rate. The gravity generated by the water flow impacting the sliding plate increases accordingly, driving the baffle assembly to slide significantly and block the control opening on the mounting plate, thereby reducing the flow area and lowering the flow rate of that branch. Conversely, the auxiliary water supply pipes farther from the inlet have lower water pressure and a smaller flow rate. The sliding plate's gravity is insufficient, and the baffle assembly only shifts slightly, maintaining a large opening in the control opening to ensure the flow rate. This makes the outflow rate of all auxiliary water supply pipes more consistent, completely solving the problem of water grabbing at the near end and water shortage at the far end caused by differences in pipeline resistance in traditional water distributors, ensuring uniform flow.

[0027] 2. After filling, the high pressure inside the tank causes water to flow back into the outlet pipe. The backflow triggers the one-way opening structure, which in turn opens the drive plate. The negative pressure generated by the backflow drives the water to rush into the pipe at high speed through the pressure tap. This high-speed water flow can form a strong flushing force, which can promptly remove impurities, scale, or media residues that have just adhered to the inner wall of the outlet pipe. It automatically cleans after each filling operation, reducing pipe narrowing and blockage caused by the accumulation of deposits from the source, and ensuring the long-term stable flow capacity of the outlet pipe. The reset spring in the one-way opening structure works with the trigger block to keep the drive plate closed when the water flows into the energy-saving tank in the forward direction, which can effectively prevent backflow of water in the tank during the normal filling stage. When filling stops and the pressure inside the tank exceeds the pressure inside the pipe, the structure can respond to the backflow in an orderly manner, avoiding the backflow water from directly impacting upstream components such as the main distribution pipe and the flow equalization pipe. This prevents these components from being damaged by the impeller or loosening of the interface due to reverse pressure and water flow impact, and plays a protective role similar to a check valve, ensuring the safety of the entire uniform flow distribution assembly.

Detailed Implementation

[0035] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0036] This application discloses a ground-mounted double-layer grid water distributor. (Refer to...) Figure 1 and Figure 2 The system includes an energy-saving tank 1, with gravity flow grilles 2 installed on the upper and lower parts of the tank 1. Each gravity flow grille 2 is divided into a first baffle 21 and a second baffle 22, with the second baffle 22 positioned near the water distribution unit 3. The first baffle 21 has multiple sets of first through holes 211, and the second baffle 22 has multiple sets of second through holes 221. The number of first through holes 211 exceeds the number of second through holes 221, causing the water flow to gradually slow down and distribute evenly. The two sets of gravity flow grilles 2 divide the energy-saving tank 1 from top to bottom into a first uniform distribution zone 11, a transition zone 12, and a second uniform distribution zone 13. Both Zone 11 and the second uniform distribution zone 13 are equipped with water distribution units 3. Each water distribution unit 3 includes a main water supply pipe 31, multiple sets of auxiliary water supply pipes 32, and multiple sets of uniformly distributed outflow components 33. The main water supply pipe 31 is installed inside the energy-saving tank 1. One end of each set of auxiliary water supply pipes 32 is uniformly connected to the main water supply pipe 31, and the uniformly distributed outflow components 33 are connected to the other end of each auxiliary water supply pipe 32. An external water source is connected to the main water supply pipe 31 inside the energy-saving tank 1. The main water supply pipe 31 evenly distributes the water flow to the connected sets of auxiliary water supply pipes 32. The uniformly distributed outflow components 33, which are connected to the auxiliary water supply pipes 32, perform secondary equalization and buffering of the water flow.

[0037] Reference Figure 1 , Figure 2 and Figure 6The uniformly distributed outflow assembly 33 includes a main water distribution pipe 331, two sets of secondary water distribution pipes 331, multiple sets of equalizing pipes 333, and multiple sets of outlet pipes 334. The main water distribution pipe 331 is connected to the other end of the secondary water supply pipe 32 in the middle. The middle of one set of secondary water distribution pipes 331 is connected to one end of the main water distribution pipe 331, and the middle of another set of secondary water distribution pipes 331 is connected to the other end of the main water distribution pipe 331. The two ends of the single set of secondary water distribution pipes 331 are respectively connected to the middle of the two sets of equalizing pipes 333. The multiple sets of outlet pipes 334 are arranged on both sides of the equalizing pipes 333. A drain pipe 9 is connected between the main water distribution pipes 331 on the multiple sets of uniformly distributed outflow assemblies 333, and a switch valve 91 is provided at the outlet end of the drain pipe 9. A water distribution head 8 is provided on the outlet pipe 334, and the water distribution head 8 includes a base plate 81 and multiple sets of isolation. Plate 82, multiple sets of isolation plates 82 are evenly arranged on the base plate 81 along the circumference of the water outlet pipe 334, and the water outlet pipe 334 is set on the isolation plate 82. The bottom of the base plate 81 is set at the bottom or top of the energy-saving tank 1. The water flow from the auxiliary water supply pipe 32 first enters the main water distribution pipe 331. The main water distribution pipe 331 distributes the water flow evenly to the two sets of auxiliary water distribution pipes 331 connected at both ends. Each set of auxiliary water distribution pipes 331 then transmits the water flow to the equalization pipes 333 connected at both ends of the auxiliary water distribution pipe 331, so that the water flow of a single set of auxiliary water distribution pipes 331 is again evenly distributed to the two equalization pipes 333. The equalization pipes 333 then transport the water flow to the multiple sets of water outlet pipes 334 arranged on both sides. After the water flow is transported to the water distribution head 8 through the water outlet pipes 334, the water flow flows out from the water outlet pipes 334 and diffuses along the isolation plate 82.

[0038] Reference Figure 3 An adjustment structure 4 is provided inside the auxiliary water supply pipe 32. The adjustment structure 4 includes a sliding plate 41, an installation pipe 42, a baffle assembly 43, and an installation plate 44. The installation pipe 42 is fixedly installed inside the auxiliary water supply pipe 32 and has multiple sets of water outlets 421. The baffle assembly 43 is slidably installed in the lower part of the installation pipe 42. The sliding plate 41 is slidably installed inside the installation pipe 42, and the bottom of the sliding plate 41 abuts against the baffle assembly 43. The installation plate 44 is fixedly installed inside the auxiliary water supply pipe 32 and is located below the installation pipe 42. The edge of the installation plate 44 has multiple sets of control openings 441 circumferentially arranged. The baffle assembly 43 includes multiple sets of sliding stops 431. The drive column 432 and the elastic ring 433 are included. The drive column 432 is slidably disposed inside the auxiliary water supply pipe 32, and the top of the drive column 432 abuts against the sliding plate 41. The sliding plate 41 is slidably disposed on the mounting plate 44. A mating inclined surface 4311 is provided on the side of one end of the sliding block 431. Multiple sets of sliding blocks 431 are arranged circumferentially along the drive column 432, and the drive column 432 abuts against the mating inclined surface 4311. The elastic ring 433 is sleeved on one end of the multiple sets of sliding blocks 431. The elastic ring 433 is used to keep the mating inclined surface 4311 of the multiple sets of sliding blocks 431 abutting against the drive column 432. The other end of the sliding block 431 is disposed on one side of the control opening 441.

[0039] When the elastic ring 433 is in a naturally tightened state, the sliding stop 431 is tightened towards the drive column 432, so that the mating inclined surface 4311 of the sliding stop 431 always abuts against the side wall of the drive column 432, controlling the opening 441 to be in the maximum opening state; after the water flows into the auxiliary water supply pipe 32, the gravity of the water flow will exert downward pressure on the sliding plate 41. When the water flow is small, the sliding plate 41 moves downward a limited distance, and the downward pressure on the drive column 432 is weak; when the water flow is large, the gravity of the water flow increases, pushing the sliding plate 41 to slide downward along the inner wall of the mounting pipe 42, and driving the drive column 432 to move downward synchronously. When the drive column 432 moves downward, the side wall of the drive column 432 slides relative to the mating inclined surface 4311 of the sliding block 431. Guided by the mating inclined surface 4311, the vertical downward movement of the drive column 432 is converted into the horizontal outward movement of the sliding block 431. When the water inflow of one set of auxiliary water supply pipes 32 is greater than that of other sets of auxiliary water supply pipes 32, the sliding plate 41 of this set experiences greater gravity, the control opening 441 is blocked more, and the water output is automatically reduced. Conversely, for auxiliary water supply pipes 32 with smaller water inflow, the control opening 441 is less blocked, and the water output is increased, thus achieving a balance in the water output of multiple sets of auxiliary water supply pipes 32.

[0040] Reference Figure 4 A buffer structure 5 is provided at the connection of the outlet pipe 334. The buffer structure 5 includes a first flow channel 51 and a second flow channel 52. The flow equalization pipe 333 is connected to the outlet pipe 334 through the first flow channel 51 and the second flow channel 52. The first flow channel 51 and the second flow channel 52 are provided with multiple sets of continuous turning sections 53. The extension directions of two adjacent sets of turning sections 53 are arranged at a preset angle, and each set of turning sections 53 is connected in sequence. The water flow passes through multiple turning sections 53, so that the flow direction changes multiple times, thereby reducing the flow velocity and impact pressure of the water flow.

[0041] Reference Figure 2 and Figure 5A pressure tap 3341 is provided on the side of the water outlet pipe 334, and a drive plate 6 is slidably mounted on the pressure tap 3341. A clearance groove 3342 is provided inside the outlet of the water outlet pipe 334, and a one-way opening structure 7 is provided within the clearance groove 3342. The one-way opening structure 7 includes a trigger block 71, a trigger groove 72, a sliding block 73, a sliding cylinder 74, and a return spring 75. The trigger groove 72 is located at the bottom of the clearance groove 3342, and one end of the trigger block 71 is slidably mounted within the trigger groove 72. The return spring 75 is sleeved on the trigger block 71, with one end fixedly mounted on the clearance groove 3342 and the other end fixedly mounted on the other end of the trigger block 71. The sliding cylinder 74 is located on the water outlet pipe 334 below the pressure tap 3341, with one end of the sliding block 73 slidably mounted within the sliding cylinder 74 and the other end fixedly mounted on the drive plate 6. One end; the trigger groove 72 is connected to the sliding cylinder 74; the water flow direction in the outlet pipe 334 is positive, the pressure in the energy-saving tank 1 is less than or equal to the pressure in the outlet pipe 334, no reverse water flow is generated, and the drive plate 6 remains closed; when the main water supply pipe 31 fills the energy-saving tank 1 with water and stops supplying water, at this time the pressure in the energy-saving tank 1 is greater than the pressure in the outlet pipe 334, the high-pressure water in the energy-saving tank 1 flows back into the outlet pipe 334, the water flow reaches the clearance groove 3342 at the outlet of the outlet pipe 334, pushing the trigger block 71 to slide into the trigger groove 72; causing the sliding block 73 in the sliding cylinder 74 to move the drive plate 6, opening the pressure tap 3341, after opening, a negative pressure flow channel is formed inside the outlet pipe 334, so that the water flow in the outlet pipe 334 is accelerated under the action of negative pressure, and at the same time, the reverse high-pressure water in the energy-saving tank 1 continues to rush in, and the high-speed water flow will flush the inner wall of the pipe in the evenly distributed outflow component 33.

[0042] The working principle of the ground-mounted double-layer grid water distributor in this application is as follows: After the external water source is connected to the main water supply pipe 31 inside the energy-saving tank 1, the water flow is initially distributed to multiple sets of evenly connected auxiliary water supply pipes 32. When the water flow enters the auxiliary water supply pipe 32, it will generate downward gravity pressure on the sliding plate 41 inside the mounting pipe 42. When the water flow rate of a certain set of auxiliary water supply pipes 32 is large, the gravity of the water flow pushes the sliding plate 41 to drive the drive column 432 to move down synchronously. The drive column 432, through the cooperation of the inclined surface 4311, squeezes the circumferentially arranged sliding block 431, so that the sliding block 431 overcomes the contraction force of the elastic ring 433 and slides outward, blocking the control opening 441 on the mounting plate 44, reducing the water supply of that set of auxiliary water supply pipes 32. The outflow area of ​​water pipe 32 is reduced to decrease the outflow rate. When the inflow rate of a certain auxiliary water supply pipe 32 is small, the downward pressure of sliding plate 41 is insufficient, and elastic ring 433 pulls sliding stop 431 to reset inward, controlling opening 441 to maintain a large opening and ensuring outflow rate. After flow regulation, the water flows into the uniform outflow component 33. The water flows from auxiliary water supply pipe 32 into the middle of main distribution pipe 331 and is evenly distributed to the two sets of auxiliary distribution pipes 331 at both ends of main distribution pipe 331. Each set of auxiliary distribution pipes 331 transmits the water flow to the equalization pipes 333 at both ends, realizing the further equalization of the water flow. The equalization pipes 333 deliver the water flow to multiple sets of outflow pipes 334 on both sides. The water flow enters the... Before the outlet pipe 334, the water flows through the first flow channel 51 and the second flow channel 52 of the buffer structure 5. Through multiple turns in the continuous turning sections 53, the kinetic energy of the water flow is consumed, the impact of the water flow is weakened, and the flow velocity is steadily reduced. After buffering, the water flows out of the outlet pipe 334 and enters the distribution head 8 area. Multiple sets of baffles 82 of the distribution head 8 are evenly distributed around the outlet pipe 334, dividing the water flow into multiple uniform streams and guiding them to diffuse in all directions. Simultaneously, the bottom plate 81 of the distribution head 8 isolates the water flow from direct contact with the bottom of the energy-saving tank 1, preventing the water flow from impacting the bottom medium layer and forming turbulence. When the water flows through the double-layer gravity flow grid 2, it first undergoes preliminary flow stabilization through the second baffle 22, and then... The first baffle 21 achieves secondary flow equalization, forming a stable flow field in the first uniform distribution area 11 and the second uniform distribution area 13 respectively, ensuring uniform distribution of cold or heat in the tank; when the main water supply pipe 31 stops supplying water and the energy-saving tank 1 is filled with water, the pressure inside the energy-saving tank 1 exceeds the pressure inside the water pipe, triggering the pipeline self-cleaning process, and the high-pressure water in the tank flows back into the outlet pipe 334. When the water flow reaches the clearance groove 3342 at the outlet of the outlet pipe 334, it pushes the trigger block 71 to slide into the trigger groove 72; the trigger groove 72 is connected to the sliding cylinder 74, and the sliding of the trigger block 71 drives the sliding block 73 in the sliding cylinder 74 to move synchronously, thereby pushing the drive plate 6 on the pressure tap 3341 to open;After the drive plate 6 is opened, a negative pressure flow channel is formed inside the outlet pipe 334. Under the action of negative pressure, the reverse high-pressure water in the tank accelerates into the pipeline. The high-speed water flow powerfully flushes the inner walls of the outlet pipe 334, the equalization pipe 333, the secondary water distribution pipe 331, and the main water distribution pipe 331 of the evenly distributed outlet components 33, removing the attached impurities. The impurities and liquid mixture generated by the flushing are collected in the main water distribution pipes 331 of each evenly distributed outlet component 33. Through the drain pipe 9 connecting all the main water distribution pipes 331, the mixture is discharged out of the tank after the switch valve 91 is opened, completing the pipeline cleaning.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
