Description

Technical Field

[0001] The present invention relates to the field of water pollution prevention and treatment technology, in particular to a secondary water supply device. Background Art

[0002] With the acceleration of urbanization, urban populations are growing rapidly, and high-rise buildings are popping up like mushrooms after a rain. However, the pressure of the municipal water supply network can usually only meet the water needs of users on lower floors. In high-rise buildings, insufficient water pressure prevents water from being delivered directly to the homes of users on the upper floors. Therefore, secondary water supply equipment has emerged as a key means to solve the water supply problem in high-rise buildings. However, as the water flow continues to flow, the water accumulated in the stabilization tank remains in a relatively stable state, causing debris and scale to accumulate inside the stabilization tank, requiring regular cleaning, which is very troublesome. At the same time, if cleaning is not carried out in a timely manner or the cleaning effect is poor due to continuous cleaning, it can easily lead to a decline in the quality of the water flow subsequently delivered, causing residents to suffer from illness. Summary of the Invention

[0003] In order to improve the problem that the existing secondary water supply equipment cannot be cleaned in time, resulting in deterioration of water quality and the cleaning effect cannot be maintained stable, the present invention provides a secondary water supply equipment.

[0004] The secondary water supply equipment provided by the present invention adopts the following technical solution:

[0005] A secondary water supply device includes a main housing, wherein both ends of the interior of the main housing are connected to the exterior with system pipelines for connecting to an external water supply system, a plurality of secondary branch pipes are connected to the bottom of the system pipeline, and the ends of the plurality of secondary branch pipes away from the system pipeline are all connected to an air pressure tank for temporarily storing water and stabilizing water pressure, a flow stabilizing tank is provided on one side of the main housing at one side of the air pressure tank, and a universal seat is connected to one side of the flow stabilizing tank and fixed to the interior of the main housing;

[0006] The swirl pot includes a tank shell universally connected to one side of the universal seat, the inner surface of the tank shell is provided with a water-guiding threaded groove for guiding the direction of water flow, a cleaning main rod is rotatably provided in the middle of the tank shell for cleaning the inner wall of the tank shell, one side of the cleaning main rod passes through the outside and is connected to a rotating connecting seat fixed to the inside of the main box body, the rotating connecting seat and the universal seat are located on both sides of the swirl pot as a whole to form a support.

[0007] By adopting the above technical solution, the cleaning main rod rotates in different directions, thereby wiping, stirring and shaking the inside of the stabilizing tank, forming a regular and stable cleaning effect inside the equipment, ensuring the water flow quality, and at the same time keeping the water flow inside the stabilizing tank in a flowing state, thereby extending the cleaning cycle inside the equipment.

[0008] Preferably, a universal ball for connecting to the universal seat is provided on the side of the tank shell facing the universal seat, and a connecting side cover is sealedly connected to the surface of the tank shell facing the rotating connecting seat to form an overall seal of the slurry tank, and a drain valve port for discharging dirty water is provided on one side of the bottom of the connecting side cover.

[0009] By adopting the above technical solution, the drain valve is used to discharge the dirty water cleaned in the tank shell. At the same time, the interior of the tank shell can be maintained by removing the connecting side cover, thereby increasing the manual maintenance method.

[0010] Preferably, the outer surface of the cleaning main rod is surrounded by a plurality of stirring blades, and a telescopic groove is provided on the side of the plurality of stirring blades facing outward. The plurality of telescopic grooves are connected to a rotating cavity provided inside the cleaning main rod, and a limit block is protruding on the opening side of the plurality of telescopic grooves in the rotating cavity.

[0011] By adopting the above technical solution, the stirring fan blades rotate in the forward and reverse directions, thereby forming two operating modes: cleaning the tank shell and stirring the water flow in the tank shell. In addition, the multiple telescopic grooves opened on the surface of the stirring fan blades reserve moving space for the subsequent deployment of the cleaning structure.

[0012] Preferably, telescopic sliders are telescopically arranged in the multiple telescopic grooves, and the ends of the multiple telescopic sliders facing the rotating cavity and the side away from the limit block are provided with extrusion slopes, and the sides of the multiple telescopic sliders facing the limit block are elastically connected to the limit block.

[0013] By adopting the above technical solution, the opening of the extrusion slope increases the contact area between the telescopic slider and the subsequent extrusion structure, thereby facilitating the expansion process from the surface of the stirring fan blade. At the same time, the telescopic slider is elastically connected to the limit block, thereby ensuring that the telescopic slider is retracted from the telescopic groove after the telescopic slider loses the extrusion force.

[0014] Preferably, expansion plates are rotatably provided on both sides of one end of the multiple telescopic sliders away from the limit block, a telescopic cavity is provided inside the expansion plate, a telescopic block is movably provided in the telescopic cavity, and an wiping wire for rubbing and cleaning the outer shell of the tank body is fixed on the surface of the telescopic block facing outward.

[0015] By adopting the above technical solution, the telescopic cavity is opened to reserve moving space for the telescopic slider, and at the same time limit the movement of the telescopic slider. As the telescopic slider moves, the expansion plate is expanded from the surface of the stirring blade, and then the erasing wire is abutted against the inner wall of the tank shell, thereby performing the erasing action.

[0016] Preferably, the cleaning main rod is located in the middle of the rotating chamber and is rotatably provided with a rotating rod, and the surface of the rotating rod located in the rotating chamber is provided with an extrusion block that is in contact with multiple extrusion slopes. One side of the rotating rod moves through the rotating chamber and passes through the outside, and a universal joint is provided at the end of the penetration, and the universal joint is connected to a rotating disk on the side away from the rotating rod.

[0017] By adopting the above technical solution, the rotation of the stirring blades drives the extrusion block to abut against the rotating rod. At the same time, the stirring blades rotate in different directions, so that the rotating rod forms two modes: directly rotating synchronously with the cleaning main rod, and the rotating rod first squeezes the telescopic slider and then rotates synchronously with the cleaning main rod.

[0018] Preferably, a guide groove is provided around a surface of one side of the rotating disk away from the universal joint, and a plurality of locking blocks are elastically provided in the guide groove.

[0019] By adopting the above technical solution, the guide groove is opened to reserve space for the connection between the rotating disk and the rotating connecting seat. At the same time, multiple locking blocks enable the rotating disk and the rotating connecting seat to be connected in two modes: non-interference rotation and synchronous rotation due to different rotation directions.

[0020] Preferably, a disk limiting groove that abuts against the rotating disk is provided on the surface of the rotating connecting seat facing the tank shell, a gear limiting groove is provided in the middle of the disk limiting groove, a gear limiting rod is fixed to the middle of the bottom of the gear limiting groove, a gear disk is meshed between the gear limiting rod and the inner wall of the gear limiting groove, and an abutment block that is plugged into the guide groove is provided on the side of the gear disk facing the rotating disk.

[0021] By adopting the above technical solution, the gear limiting rod limits the rotating disk and the gear disk in the disk body limiting groove, and the gear disk tooth surface in the gear limiting groove, respectively, to keep the gear disk rotating. At the same time, the abutment block is plugged into the guide groove to form an integral connection between the rotating disk and the gear disk, thereby keeping the rotating disk and the gear disk in a horizontal state at all times.

[0022] Preferably, a directional regulating valve is provided through the top surface of the tank shell and connected to the interior, one side of the directional regulating valve is connected to the interior of the tank shell and a water quality detection device for measuring water quality is provided, and the other side of the water quality detection device relative to the directional regulating valve is connected to the interior of the tank shell and an exhaust valve port for releasing pressure is provided.

[0023] By adopting the above technical solution, the direction regulating valve is adjusted to adjust the direction of the water flow input into the tank shell, thereby changing the rotation direction of the stirring blades. At the same time, the water quality detection device detects the water flow quality in the tank shell in real time, and releases the pressure in the tank shell through the exhaust valve port, thereby avoiding deformation and damage of the tank shell caused by excessive pressure.

[0024] Preferably, a pump body for providing suction force is provided in the middle of each of the plurality of secondary branch pipes.

[0025] By adopting the above technical solution, the pump body extracts the water flow in the stabilizing tank through the secondary branch pipe, and then transports it to the system pipeline, providing secondary water transportation power.

[0026] In summary, the present invention includes at least one of the following beneficial technical effects:

[0027] 1. Use the water quality detection device to detect the water flow in real time, and then use the stirring fan blade to drive the erasing wire clockwise to clean the inner wall of the tank shell. Assisted by the connection between the rotating rod and the rotating connecting seat, the internal wall of the stabilizing tank is wiped. At the same time, the stabilizing tank as a whole swings to produce a shaking effect, thereby timely and stably cleaning the interior of the stabilizing tank and ensuring that the water quality delivered to residents meets the use standards;

[0028] 2. By rotating the stirring blades counterclockwise, the stirring blades can speed up the water flow delivery efficiency. At the same time, the water flow inside the stirring tank is in an active state, avoiding the accumulation of debris and scale caused by long-term stagnation, thereby effectively extending the cleaning cycle inside the stirring tank.

[0043] The following is combined with Figure 1-Figure 5 The present invention is described in further detail.

[0044] An embodiment of the present invention discloses secondary water supply equipment.

[0045] Reference Figure 1 、 Figure 2 A secondary water supply device includes a main box body 1, a system pipeline 2 is fixedly provided on one side of the inner surface of the main box body 1, and the system pipeline 2 passes through both sides of the outer surface of the main box body 1 to be connected to the pipeline of the external water supply system (a seal is formed by a mounting flange at the connection point), the system pipeline 2 is located on the inner surface of the main box body 1 and is connected to a plurality of secondary branch pipes 3, and each secondary branch pipe 3 is sealed and connected to an air pressure tank 5 at one end away from the system pipeline 2, and a pump body 4 is provided in the middle of each secondary branch pipe 3, so that the input end of the pump body 4 draws water from the air pressure tank 5 and delivers it to the system pipeline 2 from the output end for external water supply;

[0046] It should be noted that the air pressure tank 5 is made of carbon steel, and the inner wall of the tank is treated with epoxy resin coating to prevent corrosion caused by contact between water and metal. There are multiple air bags inside the air pressure tank 5, and the air bags are made of butyl rubber. When water flows into the air pressure tank 5, the air bags expand and contract to absorb water pressure fluctuations, thereby maintaining system pressure stability.

[0047] Reference Figure 3 、 Figure 4, a universal seat 10 is provided on one side of the air pressure tank 5 inside the main box 1, and the flow stabilizing tank 6 includes a tank shell 61 connected to the surface of one side of the universal seat 10, and a universal ball 65 is protruded on the side of the tank shell 61 facing the universal seat 10. The universal ball 65 is universally connected with the universal seat 10, so that the tank shell 61 is universally rotated on the surface of the universal seat 10 as a whole, and at the same time, a connecting side cover 62 is screwed to the side of the tank shell 61 away from the universal seat 10, and a sealing gasket is installed at the connection between the connecting side cover 62 and the tank shell 61, and the connecting side cover 62 and the tank shell 61 are threadedly connected as a whole, and the thread type is set to NPT thread, with a tooth angle of 60° and a taper of 1:16, so that the connecting side cover 62 and the tank shell 61 form a sealed state when threaded. The connecting side cover 62 and the tank shell 61 are made of stainless steel or PVC according to the working environment, which effectively ensures that the connection parts are not corroded for a long time;

[0048] A drain valve port 64 communicating with the interior of the tank shell 61 is provided on one side of the bottom of the connecting side cover 62. The drain valve port 64 is connected to an external wastewater collection device through a pipeline. Under normal circumstances, the drain valve port 64 is in a closed state, and the opening and closing of the drain valve port 64 is controlled by an electrical signal. A directional control valve 11 is provided on one side of the top of the tank shell 61 to communicate with the interior. The directional control valve 11 is connected to an external water flow input device through a pipeline. The directional control valve 11 is provided with two valve ports in opposite directions and a rotatable valve core. The valve core is driven to rotate by an external electric control motor, thereby inputting external water flow into the two valve ports respectively, thereby adjusting the direction of water flow entering the tank shell 61;

[0049] The top of the tank shell 61 is located on one side of the directional control valve 11 and is connected to the interior thereof, and a water quality detection device 8 is provided. The water quality detection device 8 as a whole is composed of a sampling unit, a detection unit and a data processing unit, and is used to detect the water flow quality inside the tank shell 61. When the water quality does not meet the use standards, an electrical signal is sent through the data processing unit to stop the operation of the pump body 4, thereby facilitating the cleaning process of the inner surface of the tank shell 61. The top of the tank shell 61 is located on the other side of the water quality detection device 8 and is connected to the interior thereof, and an exhaust valve port 7 is provided. The exhaust valve port 7 regularly discharges the gas in the tank shell 61 to the outside, thereby avoiding deformation of the tank shell 61 and water flow discharge problems caused by air pressure expansion.

[0050] It should be noted that the bottom of the tank shell 61 is connected to the air pressure tank 5 through a pipeline, and the pipeline used to connect the tank shell 61 with the air pressure tank 5 and the water flow input device, and the pipeline connecting the drain valve port 64 with the external wastewater collection device are all set to random copolymer polypropylene pipes, which are resistant to water corrosion and ensure sealing while having good deformability. When the simmering tank 6 is tilted as a whole, there is a stretching range to prevent the pipeline from being misaligned.

[0051] Reference Figure 4 、 Figure 5 、 Figure 6 A cleaning main rod 66 is rotatably provided in the center of the tank shell 61. A plurality of stirring blades 661 are fixedly provided around the outer surface of the cleaning main rod 66 (the number of stirring blades 661 is at least four), and a telescopic groove 662 is provided inwardly on the side surface of each stirring blade 661 away from the cleaning main rod 66. The bottoms of the plurality of telescopic grooves 662 are all connected to the rotation chamber 669 provided inside the cleaning main rod 66 (the rotation chamber 669 is in communication with the plurality of telescopic grooves 662).

[0052] The rotating rod 67 is provided for rotation in the rotating chamber 669. One end of the rotating rod 67 is movably passed through the tank shell 61 and is rotatably connected to the inner wall of the slurry tank 6. The other end of the rotating rod 67 is passed through the connected side cover 62 and extends outward (so that the rotating rod 67 and the tank shell 61 are in a movably connected state). A plurality of extrusion blocks 68 are protruding from the surface of the rotating rod 67. A limit block 6610 is protruding on one side of each telescopic groove 662 and the through-opening of the rotating chamber 669. When the stirring blade 661 rotates counterclockwise as a whole, the limit block 6610 abuts against the side surface of the extrusion block 68, thereby directly driving the rotating rod 67 to rotate. When the stirring blade 661 rotates clockwise as a whole, the telescopic groove 662 rotates to a state aligned with the extrusion block 68, and then the other side of the adjacent limit block 6610 abuts against the extrusion block 68, thereby driving the rotating rod 67 to rotate as a whole (the rotation angle of the stirring blade 661 is shown in FIG. Figure 5 as a benchmark);

[0053] The multiple limit blocks 6610 are each provided with a spring on one side facing the telescopic channel 662, and a telescopic slider 663 is connected to the end of the spring. The telescopic slider 663 is positioned entirely within the telescopic channel 662 for telescopic movement. One end of the telescopic slider 663 extends into the interior of the rotation chamber 669 and is provided with an extrusion slope 664. The shape of the extrusion slope 664 conforms to the surface of the end of the extrusion block 68, thereby increasing the contact area between the telescopic slider 663 and the extrusion block 68. This allows the telescopic slider 663 to slide out of the telescopic channel 662 under the extrusion force of the extrusion block 68.

[0054] The telescopic slider 663 is rotatably provided with two opposing expansion plates 665 at one end away from the extrusion block 68. A telescopic cavity 666 is opened inward on the opposite side of the two expansion plates 665, and a telescopic block 667 is spring-mounted in the telescopic cavity 666. Under normal circumstances, the telescopic slider 663 is located in the telescopic groove 662, so that the two expansion plates 665 are fixed in a retracted state by the inner wall of the telescopic groove 662. When the telescopic slider 663 slides outward from the telescopic groove 662, the springs in the two telescopic blocks 667 are extended to generate an interaction force, pushing the two expansion plates 665 apart from each other. An erasing wire 668 is fixed on the expansion surface and the surface between the rotational connection of the two telescopic blocks 667. When the two expansion plates 665 are located on the surface of the stirring fan blade 661 and expanded, the erasing wire 668 pops out and abuts against the inner wall of the tank shell 61.

[0055] It should be noted that a water-guiding thread groove 63 is provided on the inner surface of the tank shell 61, which is used to guide the water flow input inside to increase the flow speed. The erasing wire 668 is made of polyurethane fiber with a rebound rate of 95%-99%, thereby assisting in popping out and abutting against the inner wall of the tank shell 61. At the same time, it has a high hardness to meet the wiping action of the inner wall of the tank shell 61. U-shaped sealing rubber rings are provided at the through-holes on both sides of the rotating rod 67 and the cleaning main rod 66 and the through-hole connecting the side cover 62. They fit the surface of the rotating rod 67 through elastic deformation to ensure that the rotating rod 67 rotates while ensuring that the water flow in the tank shell 61 will not leak to the outside.

[0056] Reference Figure 3 、 Figure 7 、 Figure 8 , a universal joint 69 is provided at the extended end of the rotating rod 67 that passes through one side of the connecting side cover 62, and a rotating disk 610 is fixedly provided at the other end of the universal joint 69, so that the rotating disk 610 and the rotating rod 67 can be movably offset as a whole. A rotating connecting seat 9 is fixedly provided on one side of the rotating disk 610 in the main box 1. A disk body limiting groove 92 is opened inward on the side surface of the rotating connecting seat 9 facing the rotating disk 610, and a gear limiting groove 91 is opened inward again from the center of the disk body limiting groove 92. A gear limiting rod 93 is protruded laterally from the center of the gear limiting groove 91 on the side surface of the rotating connecting seat 9. The part of the surface of the gear limiting rod 93 covered by the gear limiting groove 91 is set as a gear surface, and the part of the surface of the gear limiting rod 93 covered by the disk body limiting groove 92 is set as a smooth surface;

[0057] The universal ball 65 and the universal joint 69 are both made of stainless steel 304 to ensure corrosion resistance. Grease is applied to the joints between the universal ball 65 and the universal joint 69 to avoid wear caused by excessive friction.

[0058] A gear plate 94 is provided on the tooth surface of the gear limiting rod 93, and a gear is provided around the outer surface of the gear plate 94 that meshes with the tooth surface of the gear limiting rod 93. The gear of the gear plate 94 is movably abutted against the inner wall of the gear limiting groove 91, so that the gear plate 94 as a whole rotates in the gear limiting groove 91 with the gear limiting rod 93 as the center. Under normal circumstances, the gear plate 94 and the rotating disk 610 are in an interlaced connection, and when the gear plate 94 and the rotating disk 610 are plugged into each other, they are located in the disk body limiting groove 92, and are clamped and limited by the inner wall of the disk body limiting groove 92 and the smooth surface of the gear limiting rod 93, so that the gear plate 94 and the rotating disk 610 as a whole rotate along the inner wall of the disk body limiting groove 92 with the gear limiting rod 93 as the center.

[0059] A guide groove 611 is provided on the side of the rotating disk 610 facing the gear disk 94, and a plurality of locking blocks 612 are elastically arranged around the guide groove 611. The locking blocks 612 are all extended by rotating longitudinally with the inner wall of the guide groove 611, and a plurality of abutment blocks 95 inserted into the guide groove 611 are fixed on the side surface of the gear disk 94. When the rotating disk 610 rotates clockwise as a whole, the locking blocks 612 are engaged with the abutment blocks 95, thereby driving the gear disk 94 to rotate synchronously. When the rotating disk 610 rotates counterclockwise as a whole, the top of the locking block 612 is squeezed downward by the bottom surface of the abutment block 95, so that the rotating disk 610 cannot drive the gear disk 94 to rotate (the rotation angle of the rotating disk 610 is shown in FIG. Figure 8 as a benchmark).

[0060] It should be noted that the data processing unit of the water quality detection device 8 is electrically connected to the water flow input device to adjust the water flow input speed of the water flow input device, thereby adjusting the rotation speed of the stirring blade 661 according to different indicators of different water quality detection. The rotating rod 67 is connected to the gear plate 94 as a whole, so that the rotation weight of the rotating rod 67 is greater than the rebound force of the telescopic slider 663, thereby avoiding the situation where the stirring blade 661 cannot rotate clockwise to drive the extrusion block 68 to push out the telescopic slider 663.

[0061] The implementation principle of a secondary water supply device according to an embodiment of the present invention is as follows: when using the device, water is first delivered to the tank shell 61 by an external water flow input device, and then delivered to the system water supply pipeline through the pipeline in sequence through the air pressure tank 5, the secondary branch pipe 3 and the system pipeline 2;

[0062] Under normal conditions, the water outlet direction of the directional control valve 11 is counterclockwise (direction is Figure 4As a benchmark, when water flows into the tank shell 61, it first contacts the stirring blades 661, thereby creating a buffer and blocking the initial impact force. Then, as the water flows, it impacts the stirring blades 661, causing the stirring blades 661 to rotate. In conjunction with the texture of the water guide thread groove 63, the water is stirred by the stirring blades 661, flows along the water guide thread groove 63, and is finally transported to the air pressure tank 5 through the pipeline at the bottom of the tank shell 61, thereby helping to improve the water delivery efficiency. At the same time, as the stirring blades 661 stir, the water flow inside the tank shell 61 is always in a flowing state, effectively preventing scale condensation caused by stagnant water flow, and extending the cleaning cycle of the tank shell 61.

[0063] As the tank shell 61 is used for a longer time, scale and debris in the tank shell 61 will inevitably increase. At this time, the water quality detection device 8 will detect the water quality. When the water quality does not meet the use standards, the data processing unit will send an electrical signal to control the pump body 4 to be in a closed state, stop delivering water to the system pipeline 2, control the motor end drive direction regulating valve 11 to turn the water flow input direction to clockwise, and adjust the drain valve port 64 to an open state.

[0064] As the water flow is continuously input from the direction regulating valve 11, the stirring blade 661 is driven to rotate clockwise. As the stirring blade 661 rotates, the extrusion block 68 first abuts and squeezes against the extrusion slope 664, thereby pushing the multiple telescopic sliders 663 out of the telescopic groove 662. As the telescopic sliders 663 are pushed out, the clamping force on the two expansion plates 665 is cancelled, so that the two expansion plates 665 are horizontally expanded by the ends of the telescopic sliders 663. At the same time, the wiping wire 668 pops out and abuts against the inner surface of the tank shell 61. As the stirring blade 661 rotates, the wiping wire 668 is driven to rub against the inner surface of the tank shell 61, thereby wiping off residual debris and scale.

[0065] At the same time, the limiting block 6610 contacts the side surface of the extrusion block 68, thereby driving the rotating rod 67 to rotate as a whole. As the rotating rod 67 rotates, the locking block 612 in the rotating disk 610 is engaged with the abutment block 95, thereby forming an integral engagement between the rotating disk 610 and the gear disk 94. As the rotating rod 67 rotates, the gear of the gear disk 94 is driven to mesh with the tooth surface of the gear limiting rod 93, thereby being located in the gear limiting groove 91 and rotating. The rotating disk 610 and the gear disk 94 are integrally limited in the disc body limiting groove 92, thereby maintaining a horizontal state.

[0066] When the rotating disk 610 rotates to the top position in the gear limit groove 91, the simmering pot 6 as a whole tilts downward from the side of the rotating connecting seat 9 through the movable connection of the universal joint 69. At the same time, the other side of the simmering pot 6 is universally connected to the universal seat 10 to avoid misalignment. When the rotating disk 610 rotates to the bottom position in the gear limit groove 91, the simmering pot 6 as a whole tilts upward from the side of the rotating connecting seat 9. This reciprocating motion causes a shaking effect on the inside of the simmering pot 6. Combined with the continuous wiping action of the erasing wire 668, the scale in the simmering pot 6 is effectively removed and the debris is discharged to the outside through the drain valve port 64.

[0067] The above are merely optional embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
