Description

Technical Field

[0001] The present invention relates to the technical field of secondary water supply equipment, and in particular to secondary water supply equipment with a water pressure compensation structure and a water pressure compensation method. Background Art

[0002] The water pressure provided by the municipal water supply is limited, and the head is insufficient when it outputs water, resulting in water difficulties in the middle and high floors. Therefore, secondary water supply is needed to meet the water needs of the middle and high floors, providing the most stable guarantee for the water supply of the middle and high floors.

[0003] When in use, the secondary water supply equipment stores and pressurizes the water, and then supplies it to users in the middle and high-level through water supply pipes. The secondary water supply equipment is mainly used to make up for the insufficient municipal water supply pressure and ensure normal water use in the middle and high-level areas.

[0004] During secondary water supply, the water inside the water tank is pressurized by a water pump and then output. When supplying water, if the water inlet speed is lower than the water outlet speed, the water inside the water tank will gradually decrease, and the missing liquid will be filled with air to ensure the pressure inside the water tank. However, there is a lack of compensation for the water supply pressure. During peak water use periods, the water pressure will still weaken, resulting in a weakening of the high-rise water supply flow and affecting normal water use. Summary of the Invention

[0005] In response to the deficiencies in the prior art, the present invention provides a secondary water supply device with a water pressure compensation structure and a water pressure compensation method, which solves the problem that when the current secondary water supply equipment is supplying water, when the water inlet speed is lower than the water outlet speed, the water inside the water tank will gradually decrease, and the missing liquid will be filled with air to ensure the pressure inside the water tank. However, due to the lack of compensation for the water supply pressure, the water pressure will still weaken during peak water use periods, resulting in a weakening of the high-rise water supply flow and affecting normal water use.

The extrusion plate is slidably installed inside the pressure tank. An insertion rod is provided on the outer side of the extrusion plate.

[0018] The electromagnet is fixedly installed on the side of the extrusion plate facing the diaphragm. A magnetic block is placed inside the diaphragm. When the electromagnet is energized, it can attract the magnetic block.

[0019] The electromagnetic ring is fixed to the inner wall of the pressure tank, and a contraction portion is provided on the inner side of the electromagnetic ring, which can squeeze the diaphragm.

[0020] In one possible implementation, a pressure gauge capable of measuring the internal pressure of the pressure tank is provided on the outside of the pressure tank. The pressure gauge is fixed inside the pressure tank, and the middle portion of the diaphragm extends outward to form a U-shaped protrusion.

[0023] The arc plate is arranged on the outer side of the slider, and a connecting rod is arranged at the connection position between the arc plate and the slider. The connecting rod movably passes through the arc plate and the slider, and the arc plate can swing relative to the connecting rod.

[0024] In one possible implementation, the pipeline structure includes:

[0028] The water pump assembly is arranged in the middle of the second connecting pipe and the third connecting pipe. A flow meter and an electric regulating valve A are arranged at one end of the first water supply pipe connected to the household water end.

[0029] In one possible implementation, the flow meter is fixed outside the first water supply pipeline and detects the water flow of the first water supply pipeline, and the electric regulating valve A is set at the lower end of the flow meter to control the water flow diameter of the water outflow from the first water supply pipeline.

[0030] An embodiment of the present invention further provides a water pressure compensation method for a secondary water supply device, characterized in that the method includes the above-mentioned secondary water supply device, and the specific steps are as follows:

[0031] The water plant or municipal water supply is connected to the water collection part for water supply. The water inside the water tank enters the pipeline structure for water supply. The water supply has two states: low-peak water consumption and peak water consumption.

[0032] During low-peak water use, the water pressure inside the water collection part is sufficient. Therefore, there is less air inside the water tank. The air enters the transfer part, and the transfer part squeezes the air inside into the water storage part, so that the water storage part can store water while water is injected from the outside and drawn from the inside.

[0033] During peak water usage, the water pressure inside the water collection part is insufficient. Therefore, there is a lot of air inside the water tank, and the water tank can only be pumped out by the transfer part, and the transfer part is pumped out by the water storage part, so that the water storage part squeezes the air and the water inside the water storage part is squeezed and released, forming compensation for the water pressure of the pipeline structure.

[0034] In one possible implementation, the water storage part stores water when the water inflow of the water tank is greater than the water outflow, and is in a water storage state. The water storage part squeezes out water when the water inflow of the water tank is less than the water outflow, and is in a compensation state.

[0035] Beneficial effects

[0036] The present invention provides a secondary water supply device with a water pressure compensation structure and a water pressure compensation method. Compared with the existing technology, it has the following advantages:

[0037] 1. During the water supply process, the present invention can store a portion of water during low-peak water usage, so that the water is sealed inside the pressure tank to ensure sufficient pressure. During peak water usage, the water inside the pressure tank is released so that the water inside the pressure tank is squeezed out. During the squeezing, the water supply pressure is higher than the water outlet pressure of the pressure tank, thereby performing water pressure compensation.

[0038] 2. The present invention sets three different connecting pipelines. During use, the opening and closing of different pipelines can realize the switching between different states of water storage, peak water supply and low-peak water supply, thereby ensuring the water demand of middle and high levels, ensuring the stability of water supply, and realizing the function of automatic compensation of water pressure according to water flow.

[0039] 3. The present invention utilizes a filtering structure arranged inside the water tank, which can stably squeeze and filter the water inside the water tank during use. During the filtering process, continuous water inflow and outflow are formed, and the water inside the water tank is stirred so that the water can move toward the side of the filter screen, thereby ensuring a stable filtering effect.

[0040] 4. When supplying water to the middle and upper levels, two situations may occur. In the first situation, the water pressure when the water flows into the middle and upper levels is stable and can meet the normal water use of the middle and upper levels. In the second situation, the water flow is slow, resulting in insufficient water pressure when the middle and upper levels use water. In this case, the water stored in the pressure tank is released to compensate for the water flow pressure and ensure normal water use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0057] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0058] See also Figure 1-15The present invention provides a secondary water supply device with a water pressure compensation structure, which is used for water supply pressurization in mid- and high-rise buildings such as residential areas and commercial buildings, ensuring stable water use in mid- and high-rise buildings during peak water use periods, and capable of performing water pressure compensation to ensure water discharge head. The secondary water supply device includes a pipe structure 1 connected to the residents of the mid- and high-rise buildings, the end of the pipe structure 1 is connected to the water end of the household, and a water supply part is arranged at the upper end of the pipe. The water supply part includes a water collection part, a transfer part and a water storage part. The water collection part, the transfer part and the water storage part form a structure to supply water to the residents during low-peak and peak water use. A support frame 2 is arranged at the bottom of the water collection part, and a mounting frame 3 is arranged at the bottom of the transfer part, wherein the water collection part is connected to the mounting frame 3, and the water collection part includes:

[0059] The water tank 21 is fixedly placed above the support frame 2, and a water outlet end connected to the pipe structure 1 is extended from its bottom. The water outlet end is fixed to the pipe structure 1 by bolts. The top of the water tank 21 is provided with a water inlet end and a ventilation end. The water inlet end is used to connect to the water plant or municipal water supply. A negative pressure suppressor 22 is installed on the upper part of the ventilation end. The connection method of the negative pressure suppressor 22 and the ventilation end is the same as the connection method of the water outlet end and the pipe structure 1. The negative pressure suppressor 22 is connected to the water tank 21 and the transfer part;

[0060] The motor 23 has a lower mounting structure mounted on the inner side of the mounting frame 3 by bolts. The output end of the motor 23 passes through the rear wall of the water tank 21 and extends into the interior of the water tank 21. A connecting shaft 24 is provided on the outer side of the output end of the motor 23. The connecting shaft 24 passes through the front wall of the water tank 21 and is movably connected to the wall. The connecting shaft 24 is connected to the output end of the motor 23, and the two are coaxially arranged.

[0061] The filter screen 26 is fixedly installed between the water outlet and the water inlet of the water tank 21. Its shape is consistent with the shape of the inner side of the cross section of the water tank 21. The connecting shaft 24 passes through the filter screen 26. A driving plate 25 is provided on one side of the filter screen 26. The driving plate 25 is slidably installed on the outside of the connecting shaft 24 and can slide on the outer wall of the connecting shaft 24. The driving plate 25 extends an arc-shaped rotating plate toward one side of the filter screen 26. The arc-shaped rotating plate and the driving plate 25 are integrally provided.

[0062] The spiral groove 27 is formed on the inner wall of the water tank 21 , and a limit block 28 is provided therein. The limit block 28 is symmetrically fixed to the side of the driving plate 25 . The limit block 28 moves inside the spiral groove 27 when the connecting shaft 24 rotates.

[0063] In the present invention, the water inside the water tank 21 is squeezed so that it can be filtered more stably when the water is discharged. Since the water inside the water tank 21 can squeeze and shrink the water, the water outlet pressure can be increased when the water is supplied. When the water is supplied, the filtration speed of the filter mesh 26 is limited. After being squeezed, the water pressure increases, which can speed up the filtration speed.

[0064] In some embodiments, the connecting shaft 24 needs to drive the driving plate 25 to move, thereby squeezing the water inside the water tank 21, and also needs to drive the driving plate 25 to rotate, thereby stirring the driving plate 25. During use, the connecting shaft 24 must not only limit the rotation of the driving plate 25, but also ensure the movement of the driving plate 25. Therefore, an arc-shaped protrusion is formed on the outside of the connecting shaft 24 to limit the rotation of the driving plate 25. The arc-shaped protrusion extends to the outside of the connecting shaft 24 and contacts the inner wall of the driving plate 25. The spiral groove 27 is consistent with the position of the limit block 28, and they are all symmetrically arranged.

[0065] It can be understood that the limit block 28 on the outside of the driving plate 25 is located inside the spiral groove 27. When the driving plate 25 moves, it is restricted by the spiral groove 27 and the limit block 28, and the driving plate 25 will rotate. When the driving plate 25 rotates, it is restricted by the spiral groove 27 and the limit block 28. Therefore, the driving plate 25 will move. In this embodiment, the connecting shaft 24 forms a restriction on the driving plate 25 through the arc-shaped protrusion, thereby driving the rotation of the driving plate 25, and the limit block 28 is inside the spiral groove 27, so the driving plate 25 will rotate.

[0066] In some embodiments, the transfer part connects the water collection part and the water storage part, so that the water storage part can form corresponding actions according to the height of the water level inside the water tank 21. In order to prevent the water in the water collection part from entering the water storage part due to the collection of water and affecting the water storage part, the transfer part includes:

[0067] The transfer box 31 is fixedly mounted on the upper portion of the mounting frame 3 at its bottom. The interior of the transfer box 31 is hollow. The bottom of the transfer box 31 is connected to the negative pressure suppressor 22. A connecting pipe 35 is provided at the top of the transfer box 31. The end of the connecting pipe 35 is fixed to the top of the transfer box 31. A connector 37 is provided at the tail end of the connecting pipe 35 and is connected to the water storage part.

[0068] The moving frame 32 is slidably mounted inside the transfer box 31. A partition 33 is mounted on the inside of the moving frame 32. The edge of the partition 33 is fixed to the inside of the moving frame 32. A positioning block 34 is provided on the top of the moving frame 32 to limit the maximum upward movement of the moving frame 32. The positioning block 34 is integrally provided with the transfer box 31.

[0069] The electric regulating valve B36 is installed in the middle of the connecting pipe 35, and both ends thereof are fixedly connected to the connecting pipe 35.

[0070] Among them, the moving frame 32 is frame-shaped, and its edge contacts the inner wall of the transfer box 31 and can form a seal for the transfer box 31, and the connecting head 37 is fixedly connected to the water storage part at the end away from the connecting pipe 35. The end of the connecting head 37 connected to the connecting pipe 35 is circular, and the end of the connecting head 37 connected to the water storage part is crescent-shaped. The connecting head 37 is used for transition between the water storage part and the connecting pipe 35.

[0071] It can be understood that the cavity formed inside the transfer part is divided into two independent chambers by the moving frame 32 and the partition 33. The moving frame 32 drives the movement of the partition 33 to adjust the volume between the two chambers, thereby changing the two chambers. The bottom chamber is connected to the negative pressure suppressor 22. When the water inside the water tank 21 increases, the air inside the water tank 21 will enter the bottom chamber through the negative pressure suppressor 22, causing the moving frame 32 to drive the partition 33 to rise. When the water inside the water tank 21 decreases, the air inside the water tank 21 will be extracted from the transfer box 31 through the negative pressure suppressor 22, and the air between the transfer box 31 and the water tank 21 is complemented.

[0072] Furthermore, the electric regulating valve B36 can control the on-off of the connecting pipe 35. After the connecting pipe 35 is blocked by the electric regulating valve B36, the air inside the top chamber cannot enter the water storage part, thereby limiting the position of the moving frame 32 and the partition 33, and reducing the air entering the water tank 21 from the bottom chamber.

[0073] In some embodiments, the water storage unit has two working states: water storage and compensation. The water storage unit includes:

[0074] The pressure tank 41, like the support frame 2 and the mounting frame 3, is placed on the ground. The pressure tank 41 is connected to the connector 37. A diaphragm 43 is provided inside the pressure tank 41. The water inlet of the diaphragm 43 is fixed inside the pressure tank 41, and the diaphragm 43 is capable of expansion. An extrusion plate 44 is provided on the upper part of the diaphragm 43. The extrusion plate 44 is slidably installed inside the pressure tank 41. A rod 45 is provided on the outer side of the extrusion plate 44 to extend downward. The rod 45 is inserted into the pressure tank 41.

[0075] The electromagnet 46 is fixedly mounted on the side of the extrusion plate 44 facing the diaphragm 43. A magnetic block 49 is placed inside the diaphragm 43. The magnetic block 49 is fixed to the top of the inner wall of the diaphragm 43. When the electromagnet 46 is energized, it can magnetically attract the magnetic block 49.

[0076] The electromagnetic ring 47 is fixed to the inner wall of the pressure tank 41 , and a contraction portion 48 is provided on the inner side thereof. The contraction portion 48 can squeeze the diaphragm 43 .

[0077] The present invention does not limit the specific material of diaphragm 43. It only needs to be able to hold more water when expanded than when contracted. Those skilled in the art will be able to determine the material based on actual conditions. For example, diaphragm 43 is made of natural rubber. When water enters diaphragm 43, the increased pressure pushes diaphragm 43 to expand. In another embodiment, diaphragm 43 can also be made of butadiene rubber.

[0078] It can be understood that the diaphragm 43 is made of an elastic material that can collide. When storing water, the diaphragm 43 can expand outward so that the diaphragm 43 can accommodate more water. Due to the elastic contraction of the diaphragm 43 itself, the water inside will be squeezed so that the water can obtain a higher pressure. When discharging water, the pressure of the contraction of the diaphragm 43 is used to compensate for the insufficient water pressure during peak water use periods.

[0079] Furthermore, the position where the plug rod 45 is set is the air inlet position of the connecting head 37, and the plug rod 45 blocks the air inlet position of the connecting head 37, and the gas is squeezed into the inside of the connecting tube 35 from the top chamber, pushing the plug rod 45 upward, and the top chamber squeezes the gas into the inside of the connecting tube 35, indicating that the gas in the bottom chamber increases. Therefore, the water collection amount inside the water tank 21 is large. In this state, the water inlet speed of the water tank 21 is greater than the water outlet speed, and the water pressure is stable. It is suitable for water storage at this time. Therefore, when the plug rod 45 moves upward, it will push the extrusion plate 44 to move upward, and the amount of air inside the pressure tank 41 is limited. Therefore, the extrusion plate 44 moves upward, and the diaphragm 43 expands to store water and fill the pressure tank 41. The extrusion plate 44 operates to assist in water storage.

[0080] In some embodiments, a pressure gauge 42 capable of measuring the internal pressure of the pressure tank 41 is provided on the outside of the pressure tank 41. The pressure gauge 42 is fixed inside the pressure tank 41. In order to enable the diaphragm 43 to push the position of the contraction part 48 to change when it expands, the middle position of the diaphragm 43 extends outward to form a U-shaped protrusion, which can push the contraction part 48 upward when it expands.

[0081] It can be understood that the purpose of setting the contraction part 48 is to squeeze the diaphragm 43 when the diaphragm 43 is in the compensation state, so that the water outlet pressure of the diaphragm 43 is higher. Therefore, the larger the movement range of the contraction part 48, the greater the extrusion force on the diaphragm 43. The movement of the contraction part 48 can ensure the stability of the extrusion of the diaphragm 43.

[0082] Furthermore, when the water storage part is in the water storage state, the diaphragm 43 expands to store water. In the water storage state, the water intake inside the water tank 21 is greater than the water output, so the water pressure is sufficient; when the diaphragm 43 is in the compensation state, the diaphragm 43 itself shrinks, and the shrinking part 48 squeezes, and the water intake inside the water tank 21 is less than the water output, so the water pressure is insufficient.

[0083] In some embodiments, the contraction portion 48 needs to expand and contract during use to match the water storage expansion and compensate for the contraction of the diaphragm 43, wherein the contraction portion 48 includes:

[0084] The chutes 481 are formed on the inner wall of the pressure tank 41 and are evenly spaced. Slide blocks 482 are slidably mounted inside the chutes 481 . The slide blocks 482 extend from the inside of the chutes 481 to the inside of the pressure tank 41 .

[0085] The arc plate 483 is arranged on the outside of the slider 482, and a connecting rod 484 is set at the connection position between the arc plate 483 and the slider 482. The connecting rod 484 movably passes through the arc plate 483 and the slider 482, and the arc plate 483 can swing relative to the connecting rod 484.

[0086] It can be understood that the sliding of the slider 482 inside the slide groove 481 can drive the arc plate 483 to move up and down, and the swing of the arc plate 483 can expand and contract, thereby forming a match with the diaphragm 43. When the slider 482 is pushed upward by the diaphragm 43, the upper end of the arc plate 483 extends to the upper end of the electromagnetic ring 47, and the electromagnetic ring 47 is energized to magnetically attract the arc plate 483, so that the arc plate 483 fits the electromagnetic ring 47. When contracting, the electromagnetic ring 47 is de-energized, and the extrusion plate 44 falls. The electromagnet 46 can push the top of the arc plate 483, and the arc plate 483 moves downward. At the same time, the arc edge of the arc plate 483 contacts the electromagnet 46, slides and contracts on the surface of the electromagnet 46, and completes the extrusion of the diaphragm 43.

[0087] In some embodiments, the pipe structure 1 needs to connect the water tank 21, the pressure tank 41, and the household's water end to form a connection between the three, and needs to form different connection states according to different states. In particular, the pipe structure 1 includes:

[0088] The water inlet pipe 11 is connected to the water outlet of the water tank 21, and a first connecting pipe 12a, a second connecting pipe 12b and a third connecting pipe 12c are provided on the outside of the water inlet pipe 11. The first connecting pipe 12a, the second connecting pipe 12b and the third connecting pipe 12c are all connected to the water inlet pipe 11;

[0089] A first water supply line 13a is provided at an end of the first connecting line 12a away from the water inlet line 11, and a second water supply line 13b is provided at an end of the first connecting line 12a close to the pressure tank 41. The first water supply line 13a and the second water supply line 13b are integrally provided and both communicate with the first connecting line 12a, the second connecting line 12b, and the third connecting line 12c.

[0090] A first solenoid valve 14a is installed in the middle of the first connecting pipe 12a to control the on / off of the first connecting pipe 12a. A second solenoid valve 14b is provided in the middle of the second water supply pipe 13b to control the on / off of the second water supply pipe 13b.

[0091] The water pump assembly 15 is arranged in the middle of the second connecting pipe 12b and the third connecting pipe 12c for water supply pressurization. A flow meter 16 and an electric regulating valve A17 are arranged at one end of the first water supply pipe 13a connected to the household water end.

[0092] The water pump assembly 15 is composed of a water pump base and two water pumps. The two water pumps are connected to the second connecting pipe 12b and the third connecting pipe 12c respectively to pressurize the water passing through the second connecting pipe 12b and the third connecting pipe 12c.

[0093] It can be understood that the first water supply pipeline 13a and the second water supply pipeline 13b constitute a complete water supply pipeline. Three connecting pipelines are set between the water supply pipeline and the water inlet pipeline 11, forming different connecting states under different conditions. Among them, when the water pressure is sufficient, the first solenoid valve 14a is opened, and the water inside the water tank 21 will enter the water supply pipeline through the first connecting pipeline 12a for water supply. In another embodiment, the first solenoid valve 14a is closed, and the water pump set in the second connecting pipeline 12b works to pressurize the water and then enter the water supply pipeline. The second solenoid valve 14b is opened to store water during the water supply period. During the peak water use period, the two water pumps set in the second connecting pipeline 12b and the third connecting pipeline 12c both work to supply water.

[0094] In some embodiments, the flow meter 16 is fixed to the outside of the first water supply pipe 13a and detects the water flow of the first water supply pipe 13a, and the electric regulating valve A17 is arranged at the lower end of the flow meter 16, which can control the water flow diameter of the water outflowing from the first water supply pipe 13a.

[0095] It can be understood that the flow meter 16 is arranged at the upper end of the electric regulating valve A17 to achieve the purpose of accurate detection, and the flow meter 16 can detect the water flow and be electrically connected to the electromagnetic ring 47 and the electromagnet 46. After the flow meter 16 detects that the water flow is less than a certain predetermined value, the electromagnetic ring 47 is powered off, and the electromagnet 46 is powered off at the same time, so that the arc plate 483 can shrink inward under the extrusion of the electromagnet 46, forming an extrusion on the diaphragm 43, and the water outlet diameter can be adjusted by adjusting the solenoid valve A, thereby ensuring the pressure of the pipeline structure 1.

[0096] An embodiment of the present invention further provides a water pressure compensation method for a secondary water supply device, characterized in that the method includes the above-mentioned secondary water supply device, and the specific steps are as follows:

[0097] The water plant or municipal water supply is connected to the water collection part for water supply. The water inside the water tank 21 enters the pipe structure 1 for water supply. The water supply has two states: low-peak water use and peak water use.

[0098] Among them, the water plant or municipal water supply is connected to the water tank 21. After the water is filtered through the filter net 26, it enters the water inlet pipe 11, and then enters the first water supply pipe 13a for water supply after passing through different connecting combinations of the first connecting pipe 12a, the second connecting pipe 12b and the third connecting pipe 12c.

[0099] During low-peak water use, the water pressure inside the water collection part is sufficient. Therefore, there is less air inside the water tank 21. The air enters the transfer part, and the transfer part squeezes the air inside into the water storage part, so that the water storage part stores water while water is injected from the outside and drawn from the inside.

[0100] During peak water usage, the water pressure inside the water collection part is insufficient. Therefore, there is a lot of air inside the water tank 21, and the water tank 21 can only be evacuated by the transfer part, and the transfer part is evacuated by the water storage part, so that the water storage part squeezes the air, and the water inside the water storage part is squeezed and released, forming compensation for the water pressure of the pipeline structure 1.

[0101] During peak water usage, the water inside the diaphragm 43 will be squeezed out, so that water is supplied at a pressure higher than that of the pipeline structure 1.

[0102] In some embodiments, the water storage part stores water when the water inflow of the water tank 21 is greater than the water outflow, and is in a water storage state. The water storage part squeezes out water when the water inflow of the water tank 21 is less than the water outflow, and is in a compensation state.

[0103] The circuits and electronic components involved in the present invention are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to internal structures and methods. It should be noted that the standard parts used in the present invention can be purchased from the market, and special-shaped parts can be customized according to the description and drawings.

The machinery, parts and equipment all adopt conventional models in the existing technology, and the inventor will not elaborate on them here.
