Description

Secondary water supply equipment

Technical Field

The invention belongs to the technical field of water supply and secondary water supply, and particularly relates to secondary water supply equipment.

Background

In modern society, high-rise buildings are common, living water of the high-rise buildings is supplied to a water supply device, wherein secondary water supply equipment is one of the common water supply devices. The secondary water supply is a form that a unit or an individual stores and pressurizes urban public water supply (water supplied by a municipal water supply network) and supplies the urban public water supply to users or users through pipelines. To take a simple example: set up a water tank on the roof, set up the pressurization suction pump between water tank and the municipal water supply network, the water tank can be taken out with the water that municipal water supply network supplied with to the pressurization suction pump, and the water tank supplies water for users again.

The municipal water supply network itself has water supply pressure, and to the low-rise user, the water supply pressure of municipal water supply network can be directly with water supply to the household, but, to the high-rise user, the water supply pressure of municipal water supply network is not enough with water direct supply to the household, so need assist the water supply through devices such as extra pressurized water pumps. The problem of water cut-off is closely related to the secondary water supply equipment, and how to reasonably deal with various water cut-off conditions after water is cut off is also a problem to be considered.

Briefly described: in the foregoing, the "high-level users" and the "low-level users" are classified according to whether the water supply pressure of the municipal water supply network can directly supply water to the users, and those users who can directly supply water to the users only by the water supply pressure of the municipal water supply network are regarded as the low-level users, and the rest are the high-level users. The water cut-off can be divided into 'water cut-off type water cut-off' and 'power cut-off type water cut-off'; if the pressure water pump is the former, the pressure water pump cannot pump water from the municipal pipe network, so that water cannot be supplied in the main water supply tank, and water can be cut off for both high-rise users and bottom-layer users; if the water supply pressure is lower than the water supply pressure, the municipal pipe network supplies water to the high-rise users directly.

The main water supply tank is higher than any high-rise user, and the auxiliary adjusting tank is higher than any low-rise user but lower than any high-rise user.

At ordinary times, the water that municipal water supply network supplied is supplied with and is supplied into vice regulation water tank through first delivery pipe, and low level user's water is directly provided by vice regulation water tank, and the pressurization suction pump draws water from vice regulation water tank through the second delivery pipe, and rethread third delivery pipe supplies water into main supply water tank, and high level user's water is directly provided by main supply water tank. For the main water supply tank, when the top air hole is blocked by the main blocking ball, the main water supply tank can be regarded as a section of 'thick water pipe' between the third water supply pipe and the main water outlet pipe, at the moment, the water supply pressure of each stage is hardly lost, and the municipal water supply pipe network and the pressurizing water pump are equivalent to continuous pressurization. At the peak of water use, in a short time, the water flowing out of the main supply water tank is more than the water entering the main supply water tank, and at the moment, the water in the main supply water tank is needed to realize flow supplement, so the water level in the main supply water tank can be reduced, the main floating block, the main ball connecting rod and the main ball plug can be reduced together until the main ball plug leaves the main exchange air hole, and at the moment, the original water supply pressure of the municipal water supply network and the pressurization water pump can lose a part or even all, but the water quantity of a user side can be ensured to be sufficient.

When "the formula of having a power failure cuts off the water" when taking place, the low level user does not cut off the water, and the pressurization suction pump is because the power failure stop work, and high level user cuts off the water, and at this moment, should be before resumeing the water supply, the time that high level user can "use water" is prolonged as far as possible, and this just needs carry out reasonable management and control allotment to supplying water, and will avoid some special extravagant circumstances. The water level in the main supply water tank is continuously reduced, when the water amount in the main supply water tank is less than eighty percent of the volume of the main supply water tank, the main flow limiting plate contacts the main supporting block, the height of the lowest point of the main flow limiting plate is consistent with the height of the axis of the main water supply hole, and the inside of the main supply water tank is communicated with the main water supply hole, namely, the water can be used by a high-rise user in a throttling mode under the premise of keeping other conditions unchanged. Because the low-rise user does not cut off the water supply, the high-rise user cuts off the water supply, in case the water in the main supply water tank is used up, the high-rise user still must go to the emergent water intaking of emergency point of one floor, but the high-rise building is the elevator room, in case need walk the emergent water intaking of one floor of stair go, walk the stair again and go upstairs and go home, intensity of labour is too big, in this scheme, the high-rise user can go to vice regulation water tank department emergent water intaking, and need not go to one floor to get water, this has just greatly reduced intensity of labour, has improved the relative convenience of emergent water intaking. When emergency water taking is carried out, the water flow on-off valve is opened, and the manual water taking pump is operated to take emergency water. The manual water taking pump can be any conventional manual water pump as long as water can be taken.

In addition, as mentioned above, in practical application, when the pressurizing water pump works normally and the main blocking ball blocks the top air hole, each stage of pressurization is performed continuously, but when the power failure type water cut-off occurs, the second water supply pipe, the pressurizing water pump, the third water supply pipe, the interior of the main water supply tank and the top air hole are a water supply pressure loss channel, so that the high-rise water pumping electromagnetic valve is electrified and normally opened, the high-rise water pumping electromagnetic valve is power failure and normally closed, and when the power failure occurs, the second water supply pipe is directly blocked, so that the water supplied by the municipal water supply network can directly reach the user end through the auxiliary adjusting water tank and the auxiliary water outlet pipe, and the loss of the water supply pressure can.

When the 'water cut-off type water cut-off' occurs, the low-level user cuts off water, the high-level user cuts off water, at the moment, the pressurizing water pump can work, if the pressurizing water pump is left to continue pumping water, the water (the water in the auxiliary regulating water tank) which can be originally supplied to the low-level user for emergency can be pumped away, and the integral allocation is not facilitated, so that the 'water cut-off type water cut-off' is a relatively more reasonable and fair mode that the water in the main supply water tank is ensured to continue emergency use for the high-level user, and the water in the auxiliary regulating water tank is ensured to continue emergency use for the low-level user. In the present case, when the "water cut-off type water cut-off" occurs, the change of the main supply water tank is the same as that of the main supply water tank after the "water cut-off type water cut-off" occurs, and the change of the auxiliary regulation water tank is as follows: when the water quantity in the auxiliary regulating water tank is less than or equal to eighty percent of the volume of the auxiliary regulating water tank, the auxiliary hole sealing plate completely seals the auxiliary tank water pumping hole, the auxiliary stay cable is in a tensioning state, therefore, the supply water tank and the auxiliary regulating water tank are mutually independent, and the water in the auxiliary regulating water tank is completely supplied to low-rise users for emergency use.

It should be noted that the above functions are mainly directed to sudden water cut-off, because if the water cut-off is controlled (there is an early notification), the user can take water in advance, and there is basically no serious water shortage problem. In addition, the fact that the low-level users stop water and the high-level users stop water finally means that the low-level users stop water and the high-level users stop water finally, and actually, the water cannot be stopped immediately due to the fact that the main supply water tank and the auxiliary adjusting water tank are in the main supply water tank and the auxiliary adjusting water tank when the water is stopped.

The main water supply hole and the main water outlet pipe are coaxially arranged, the axis of the main water supply hole is horizontal, the aperture of the main water supply hole is equal to the inner diameter of the main water outlet pipe, the lowest point of the main water supply hole is located at the same height as the bottom surface in the main water supply tank, the auxiliary water supply hole and the auxiliary water outlet pipe are coaxially arranged, the axis of the auxiliary water supply hole is horizontal, the aperture of the auxiliary water supply hole is equal to the inner diameter of the auxiliary water outlet pipe, and the lowest point of the auxiliary water supply hole is located at the same height as the bottom.

The water inlet end of the high-rise service pipe is communicated with the water outlet end of the main water outlet pipe through a middle pipeline, the water inlet end of the low-rise service pipe is communicated with the water outlet end of the auxiliary water outlet pipe through a middle pipeline, the middle pipeline comprises a horizontal control pipe 61 and a vertical control pipe 62, and in the middle pipeline: an inner shaft bracket 611 and a plurality of guide vanes 612 are arranged in the horizontal control pipe, a side hole 62a communicated with one end of the horizontal control pipe is arranged on the side wall of the vertical control pipe, an outer shaft bracket 621, a pull rope 622, a taper pipe 63, a pipe sealing ball 631 capable of sealing the taper pipe and a lower magnetic ring 64 arranged below the pipe sealing ball are arranged in the vertical control pipe, an impeller shaft 65 which is coaxially arranged with the horizontal control pipe and is rotatably connected with the inner shaft bracket is arranged on the inner shaft bracket, the impeller shaft passes through the side hole and is rotatably connected with the outer shaft bracket, the guide vanes are coaxially fixed with the impeller shaft, the inner diameter of the taper pipe is sequentially increased from top to bottom, a sealing sleeve 632 which is fixedly sealed with the inner wall of the vertical control pipe is arranged at the lower end of the taper pipe, an upper magnetic ring 66 which is arranged above the lower magnetic ring and can be mutually attracted and fixed with the lower magnetic ring is arranged on the sealing sleeve, the pull rope passes through, the lower connecting rod is connected with a lower magnetic ring through an outer connecting rod 634, the lower magnetic ring is in sliding fit with a vertical control tube, an elastic rubber sealing piece 623 is arranged in the vertical control tube and is fixedly sealed with the inner side wall of the vertical control tube, a vertical push rod 624 for pushing a tube sealing ball is arranged in the vertical control tube, the upper end of the vertical push rod is connected with the elastic rubber sealing piece, when the tube sealing ball is positioned below the conical tube, the upper magnetic ring is separated from the lower magnetic ring, and when the upper magnetic ring and the lower magnetic ring are mutually attracted and fixed, the tube sealing ball seals and blocks the conical tube;

The flow guide direction of the flow guide impeller in the middle pipeline butted with the main water outlet pipe is from the main water outlet pipe to the side hole through the flow guide impeller, and the flow guide direction of the flow guide impeller in the middle pipeline butted with the auxiliary water outlet pipe is from the auxiliary water outlet pipe to the side hole through the flow guide impeller.

As mentioned above, before the water supply is resumed, it is desirable to prolong the time that users can use water as much as possible, and to perform reasonable management and control and allocation on the water supply, and avoid some special waste situations. For example, a user turns on a faucet before or after water is cut off, but forgets to turn it off. For another example, a user may use water for a long time (which may be a nuisance at ordinary times, but may be considered a "special waste situation to some extent" during periods of water outage, and it may be desirable to control such continuous use of water). Users in this paragraph refer to those facing the outage, and those not facing the outage are not in this column.

Aiming at high-rise users after power failure type water cut-off and high-rise users after water cut-off type water cut-off: in the scheme, when water and power are not cut off, the annular electromagnet is electrified and magnetized, the lower magnetic ring can be attracted (the annular electromagnet is not directly contacted with the lower magnetic ring and is fixed through magnetic adsorption), and the lower magnetic ring pulls the impeller shaft through the outer connecting rod, the lower connecting rod and the inhaul cable, so that the impeller shaft cannot rotate. When water is cut off, if the water is cut off, the power supply circuit of the pressurizing water pump is manually cut off, or the power supply circuit of the pressurizing water pump is automatically (or manually) cut off by using a controller (at the moment, the pressurizing water pump is temporarily useless, and the pressurizing water pump is stopped), and if the water is cut off by the power failure, the power supply circuit of the pressurizing water pump is naturally cut off. After the power is cut off, the annular electromagnet is out of power and has no magnetism, when a high-rise user uses water, water flow drives the guide impeller to rotate, the impeller shaft also rotates, and the inhaul cable is wound, so that the pipe sealing ball, the lower connecting rod, the outer connecting rod and the lower magnetic ring are driven to ascend. When the high-rise user continuously uses water, the lower magnetic ring continuously rises, but as long as the lower magnetic ring does not rise to the height mutually attracted with the upper magnetic ring, once the high-rise user stops using water, the lower magnetic ring can fall again under the action of gravity and finally falls to the lowest position. However, if some special conditions mentioned above occur, such as before or after water cut, a high-rise user opens the faucet but forgets to close the faucet, and if a high-rise user uses water for a long time, the impeller rotates continuously and finally drives the lower magnetic ring to rise to a height that the lower magnetic ring attracts the upper magnetic ring through the guy cable, the lower magnetic ring attracts the upper magnetic ring to fix the upper magnetic ring, and the pipe sealing ball seals the taper pipe, so that the high-rise user cannot continue to use water, and then if the high-rise user opens the faucet before or after water cut, but forgets to close the faucet, the water can be avoided from being wasted continuously, if the high-rise user uses water for a long time, the high-rise user needs to reach the position (such as an equipment room) of the present invention, presses the elastic rubber sealing sheet with fingers, so that the pipe sealing ball is pushed down through the vertical push rod and leaves the upper magnetic ring, and the magnetic ring falls under the action of gravity, and finally falls to the lowest position, and then a high-rise user can continue to use water. Therefore, the problem that a high-rise user turns on the water faucet before or after water cut but forgets to turn off the water faucet is solved, the special condition that the high-rise user always uses water for a long time is reasonably avoided, and the high-rise user can restore the water supply by himself or herself aiming at the latter condition, so that the water control and reminding functions are achieved, and the high-rise user cannot continue to use water.

Aiming at the low-level users after the water cut-off type water cut-off: in the scheme, when water and power are not cut off, the annular electromagnet is electrified and magnetized, the lower magnetic ring can be attracted (the annular electromagnet is not directly contacted with the lower magnetic ring and is fixed through magnetic adsorption), and the lower magnetic ring pulls the impeller shaft through the outer connecting rod, the lower connecting rod and the inhaul cable, so that the impeller shaft cannot rotate. When the water supply is cut off, the power supply circuit of the pressurizing water pump should be manually cut off, or the power supply circuit of the pressurizing water pump should be automatically (or manually) cut off by using a controller (at this time, the pressurizing water pump is temporarily useless, and the system should be stopped). After the power is cut off, the annular electromagnet is de-energized and has no magnetism, when a user in a lower layer uses water, water flow drives the guide impeller to rotate, the impeller shaft also rotates, and the inhaul cable is wound, so that the pipe sealing ball, the lower connecting rod, the outer connecting rod and the lower magnetic ring are driven to ascend. When the low-level users continuously use water, the lower magnetic ring continuously rises, but as long as the lower magnetic ring does not rise to the height mutually attracted with the upper magnetic ring, once the low-level users stop using water, the lower magnetic ring can fall again under the action of gravity and finally falls to the lowest position. However, if some special situations mentioned above occur, such as the low-level user opens the faucet before or after water cut but forgets to close, or if a certain low-level user uses water for a long time, the impeller continuously rotates and finally drives the lower magnetic ring to rise to the height of attracting the upper magnetic ring through the guy cable, and finally the lower magnetic ring and the upper magnetic ring attract and fix each other, and the pipe sealing ball seals the taper pipe, so that the low-level user cannot continue to use water, so that if the low-level user opens the faucet before or after water cut but forgets to close, the situation of "the low-level user uses water for a long time" is adopted, the low-level user needs to reach the position (such as a device room) of the present invention, and presses the elastic rubber sealing sheet with a finger, so that the pipe sealing ball is pushed down through the vertical push rod, and the lower magnetic ring leaves the upper magnetic ring, and fall under the action of gravity, the lower magnetic ring finally falls to the lowest position, and then a user at a lower layer can continue to use water. Therefore, the problem that the lower-layer user turns on the water faucet before or after water cut but forgets to turn off the water faucet is solved, the special condition that the lower-layer user uses water for a long time is reasonably avoided, and the lower-layer user can restore water supply by himself aiming at the latter condition, so that the water control and reminding functions are achieved, and the condition that the lower-layer user cannot continue to use water is avoided. In any case, the plugging of the conical pipe by the pipe sealing ball can be released by pushing down the vertical push rod to push down the pipe sealing ball as long as necessary.

The vertical control pipe is internally provided with a rod seat 625 fixed with the vertical control pipe, a vertical push rod penetrates through the rod seat and is in sliding fit with the rod seat, the sliding direction of the vertical push rod is vertical, the vertical push rod penetrates through the upper end of the taper pipe, and the lowest point of the elastic rubber sealing sheet is positioned above the highest point of the horizontal control pipe. When the elastic rubber sealing piece is in a horizontal state and the upper magnetic ring and the lower magnetic ring attract each other, the vertical distance between the lower end of the vertical push rod and the highest point of the tube sealing ball is less than 3 mm. The existence of pole socket can ensure to erect the push rod and have stable controllable motion route, erects the push rod lower extreme and seals the pipe ball interval less, does benefit to the user and pushes away to seal the pipe ball through pushing down elastic rubber mounting, erecting the push rod.

The top of the vertical control pipe is provided with a hard protection screen plate 67 fixed with the vertical control pipe, the hard protection screen plate is horizontally arranged, and when the elastic rubber sealing piece is in a horizontal state, the distance between the elastic rubber sealing piece and the hard protection screen plate is less than 20 mm. Because of water pressure, when can filling up water in the vertical accuse pipe (when not stopping water, often have such a condition), on this basis, because of water pressure, still can lead to the elasticity rubber mounting to upwards swell, in order to avoid the elasticity rubber mounting upwards to swell excessively, set up hard protection otter board, can avoid the elasticity rubber mounting excessively upwards to swell to protect the elasticity rubber mounting. When the elastic rubber sealing sheet and the vertical push rod need to be pressed down to push the tube sealing ball, fingers penetrate through meshes of the hard protection screen plate to press down the elastic rubber sealing sheet and the vertical push rod.
