Description

Self-pressure type water supply installation without tower

The utility model belongs to a kind of family expenses self-pressing type ground tower-free water supplying, and its control device belongs to technical field of automation.

Along with the decline year by year of groundwater table, no matter city or rural area have felt that all water is relatively more nervous, the building in the city particularly, and usually because hydraulic pressure is too low, tap water be can not enter high building, brings very big inconvenience for resident's life.More existing in the market tower-free water supplyings come out, and also solved some people difficulty now, but they also exist shortcoming separately respectively.As: no water storage device has a power failure and just can not use; Hydraulic pressure is very little, and water can not be gone up higher floor; The startup of water pump is that the switch by water pipe is determined, no matter emit how much water, as long as water pipe is opened, water pump just starts, and so not only wastes a large amount of electric energy, has also shortened the application life of water pump; What the element of control circuit adopted is relay, the wireless device around not only disturbing, and the time one is long, contact oxidation, resistance increases, and circuit can not be unimpeded, and water pump is with regard to cisco unity malfunction.

The purpose of this utility model is very to the deficiencies in the prior art, designs a kind of tower-free water supplying with storage tank, and control section adopts automatic switch control, and water pump can be according to the variation of hydraulic pressure in the storage tank and start-stop automatically.

The utility model as shown in Figure 1, mainly by pressure water storage case (3), electrically contact electrode pressure table (2), control circuit box (1), outlet pipe (11), waterproof pump box (4), self prime pump (8), sewage draining exit (10), support (9) etc. and form.Its key is: storage tank (3) is a drum shape, electrically contact electrode pressure table (2) be fixed on storage tank (3) on cover, at pressure meter behind, a control circuit box (1) is arranged, the automatic switch control circuit is enclosed in the box, in box, draw an attaching plug (12), can directly insert the 220v electrical socket; A waterproof pump box (4) is arranged below storage tank (3), and self prime pump (8) is installed in wherein, around the casing movable asbestos insulation board (5) is installed, and to prevent winter weather cold that water pump is freezing, can extract sheet asbestos out summer; In storage tank (3) bottom an outlet pipe (11) is arranged, can connect water tap; In waterproof pump box (5) back, a sewage draining exit (10) is arranged at the bottom of storage tank (3).Because directly contain some silt particles in the underground water of extracting out, can open the silt particle in sewage draining exit (10) the cleaning storage tank (3) in use for some time.

Circuit theory of the present utility model as shown in Figure 2, the automatic switch control circuit is installed in the pressure meter control circuit box (1) behind.The automatic switch control circuit mainly is made up of R-S trigger, rectification circuit, under-voltage protecting circuit, overvoltage, holding circuit that integrated circuit TC4011 constitutes.Movable contact T connects manometric pressure pointer, and links to each other with ground wire; Stationary contact T ₁, connect manometric low pressure limit point, and and BG ₃Negative pole link to each other; Stationary contact T ₂Connect pressure meter upper pressure limit point, and and BG ₄13 pin of positive pole, TC4011 link to each other, and through R ₆Ground connection.

Rectification circuit of the present utility model is mainly by C ₁, C ₂, R ₁, R ₂, D ₁, D ₂Constitute half-wave rectifying circuit; Under-voltage protecting circuit is by BG ₃Reach the adjustable resistance R that extremely links to each other with its control ₃Constitute; Overvoltage crowbar is by BG ₄Reach the adjustable resistance R that extremely links to each other with its control ₄Constitute.For the ease of in particular cases using, can be at bidirectional triode thyristor BG ₁Last hand switch K in parallel, water pump is not having under the situation of opening automatically, if need pump operation, only need open K switch, and water pump promptly starts to work.

The operating principle of automatic switch control circuit of the present utility model is: the command signal of this on-off circuit is sent by pressure meter, and the pressure in storage tank drops in limited time (supposes 0.8kg/cm ²), movable contact T and stationary contact T ₁Contact makes circuit turn-on, the S(8 pin of the R-S trigger that integrated circuit TC4011 constitutes) become low level by high level, R-S flip-flop operation state turnover, 9,11,5,6 pin become low level, and 4 pin are high level, controllable silicon BG ₂Conducting triggers BG ₁Conducting, starting of pump station work.Pressure in the storage tank (3) is by ashamed rising, when pressure is raised in limited time (supposition 2.5kg/cm ²), movable contact T and stationary contact T ₂The contact conducting, the R(13 pin of integrated circuit) become low level by high level, 9,11,5,6 pin become high level, and 4 pin become low level, BG ₂End BG ₁Also end, water pump quits work.BG ₃With R ₃Constitute under-voltage protecting circuit, as line voltage U ₀When dropping to 170v by 220v, supply voltage U ₁Drop to 6.2v by 8v, BG ₃End T and T ₁With the S(pin) can not constitute the loop, so BG ₂, BG ₁Can't conducting; BG ₄With R ₄Constitute overvoltage crowbar, work as U ₀When being raised to 245v by 220v, U ₁Be elevated to 9v by 8v, BG ₄Conducting makes the R(13 pin) become low level, 4 pin also become low level, BG ₂, BG ₁End, water pump quits work, thereby has protected water pump.Owing to adopted integrated circuit TC4011(operating voltage 3-15v), so even U ₀Be elevated to 400v, U ₁Be elevated to 14.5v, circuit itself can not damage.

Brief description is the annexation between each element in this circuit once: Fig. 2 is the control circuit schematic diagram, and Fig. 3 is an integrated circuit TC4011 schematic diagram, and 1,2,3,14 pin of TC4011 connect positive source, 7 pin ground connection, and 8 pin are through R ₇Connect positive source, through R ₈Ground connection, and and BG ₃Positive pole link to each other; BG ₃The control utmost point pass through R ₃Connect positive source, BG ₃Negative pole and stationary contact T ₁Link to each other; 9 pin of TC4011 link to each other with 11 pin, 5 pin, 6 pin, and 10 pin link to each other with 12 pin; 13 pin are through R ₅Connect positive source, through R ₆Ground connection, and with stationary contact T ₂, BG ₄Positive pole link to each other BG ₄The control utmost point through R ₄Connect positive source, BG ₄Minus earth; 4 pin of TC4011 meet BG ₂The control utmost point, BG ₂Positive pole connect positive source, BG ₂Negative pole meet BG ₁The control utmost point, t ₂Ground connection, t ₁Meet output B, K switch and BG ₁In parallel; R ₁, C ₁Meet output (going into) end A, and pass through R ₂With D ₁Positive pole link to each other, with D ₂Negative pole link to each other D ₂Plus earth, D ₁Negative pole meet C ₂Positive pole, C ₂Minus earth.

The utility model has the advantages that: hydraulic pressure is adjustable, can deliver to building more than 3 layers to water; The circuit start mode both can automatically also can be manual; Because storage tank (240L) is arranged, can emit 160L water after the power failure, can guarantee that a family of five used one day, and through the storage tank post precipitation, the water clean hygiene of emitting; Have under-voltage and overvoltage crowbar, all can normally use, brownout and too highly can not damage water pump at 170V and 245V voltage range.The utility model is particularly suitable for the rural area and uses, solved they draw water from a well or from pumped well setting-out, the difficulty of the not only unhygienic but also gas of requiring great effort, it is lower and the difficulty that can not go upstairs is easy to install also to have solved higher level building tap water pressure.
