Description

A kind of micro water level controller
Technical field
The present invention relates to water culture technique fields, and in particular to a kind of micro water level controller.
Background technique
In the water resources application field such as plant culture, irrigation, draining, it usually needs carry out constant control to water level, such as exist Liquid culture field needs to keep the constant level of nutrient solution to meet the growth demand of plant, realizes the function at present all The water level control system by water level sensor and component complexity is needed, this mode is not only at high cost, builds, debugging process It is complicated cumbersome, and failure is easy to appear using electric member, also it is unfavorable for while increasing maintenance cost to water level Control.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of micro water level controller, make it have it is simple and reliable for structure, It is at low cost, be able to achieve the advantages of constant control reliable to liquid level.
The present invention is solved the above problems by following technological means:
A kind of micro water level controller, including water storage cavity and the water storage chamber lid being arranged at the top of water storage cavity, the water storage cavity Side wall be provided with grid, the water storage cavity, which covers, is provided with intake tunnel, is provided with floating body in water storage cavity, above the floating body It is provided with blocking, floating body, which moves up and down, can drive blocking to close or open intake tunnel.
Further, laborsaving lever is provided at the top of the floating body, one end of the laborsaving lever and the side wall of water storage cavity are cut with scissors Composition fulcrum, the force end in contact of floating body and laborsaving lever are connect, the blocking is arranged at the top of laborsaving lever and close to fulcrum One end.
Further, the water storage chamber inner sidewall is provided with vertically extending guide post, is provided with and is oriented on the floating body The guide groove that column is slidably matched.
Further, the water storage cavity side wall is provided with hinged seat, and the laborsaving lever is hinged by shaft and hinged seat.
Further, the top of the intake tunnel is provided with the connector being connected to intake tunnel.
Further, the bottom end of the intake tunnel is provided with made of soft elastic material and is connected to intake tunnel Diversion pipe, the sectional area of the blocking are greater than the sectional area of diversion pipe.
Beneficial effects of the present invention: the micro water level controller of the application, including water storage cavity and setting are at the top of water storage cavity Water storage chamber lid, the side wall of the water storage cavity is provided with grid, and the water storage cavity, which covers, is provided with intake tunnel, sets in water storage cavity It is equipped with floating body, blocking is provided with above the floating body, floating body, which moves up and down, can drive blocking to close or open intake tunnel.The knot The micro water level controller of structure, have the advantages that it is simple and reliable for structure, at low cost, be able to achieve to the reliable constant control of liquid level.
Detailed description of the invention
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is schematic perspective view of the invention;
Fig. 2 is the top view for removing water storage chamber lid;
Fig. 3 is the structural schematic diagram of water storage chamber lid.
Specific embodiment
Below with reference to attached drawing, the present invention is described in detail.
As shown in Figure 1-3, the micro water level controller of the application, including water storage cavity 1 and the storage being arranged at the top of water storage cavity Water cavity lid 2, the side wall of the water storage cavity are provided with grid 3, and the water storage cavity, which covers, is provided with intake tunnel 4, and the water inlet is logical The top in road is provided with the connector 12 being connected to intake tunnel, and the connector is fixedly connected with water outlet chamber lid, can be square by connector Just it is fast connected to extraneous water system or water supply line.It is provided with floating body 5 in water storage cavity, is provided with above the floating body stifled Plug 6, floating body, which moves up and down, can drive blocking to close or open intake tunnel.When specifically used, intake tunnel and extraneous water supplying pipe Road connection, which is mounted in the container for needing constant level, the liquid in container enters water storage cavity by grid Interior, it is consistent with the liquid level of container that the mounting height of water level controller should meet the liquid level in water storage cavity, when liquid level reaches in container When to predetermined fluid level, for floating body under the action of buoyancy, driving blocking moves up blocking intake tunnel at this time, realizes the pass of intake tunnel It closes.As aqueous solution is evaporated or absorbs in container, liquid level is moved down, and floating body is also synchronized and moved down at this time, and blocking is driven to open water inlet Channel supplements aqueous solution, and during aqueous solution supplement, floating body gradually moves up under buoyancy, when liquid level reaches predetermined value When, blocking can close intake tunnel again, repeatedly, the auto-control of liquid level may be implemented.In conclusion the structure Micro water level controller, have the advantages that it is simple and reliable for structure, at low cost, be able to achieve to the reliable constant control of liquid level.In addition, Vertically extending guide post 10 is arranged in water storage chamber inner sidewall, and the guide groove 11 being slidably matched with guide post is arranged on floating body, with Just moving up and down for floating body is oriented to.
As further improvement to above-mentioned technical proposal, laborsaving lever 7, the laborsaving thick stick are provided at the top of the floating body One end of bar and the side walls hinged composition fulcrum 8 of water storage cavity, specifically, the water storage cavity side wall is provided with hinged seat, described Laborsaving lever is hinged by shaft and hinged seat.The floating body is contacted with the bottom of the force side 9 of laborsaving lever, and the blocking is set Set one end at the top of laborsaving lever and close to fulcrum.By the effect of laborsaving lever, in the case where buoyancy is constant, can improve The blocking power to intake tunnel is blocked, thus it is advantageously ensured that the effect closed to intake tunnel blocking.
As further improvement to above-mentioned technical proposal, the bottom end of the intake tunnel is provided with by soft elastic material Diversion pipe 13 that is manufactured and being connected to intake tunnel, the diversion pipe as made of elastic rubber can be voluntarily after flexible deformation Restore deformation;The sectional area of the blocking is greater than the sectional area of diversion pipe.During closing intake tunnel, blocking first with Diversion pipe contact can squeeze diversion pipe bending deformation, make diversion pipe seal itself, in conjunction with stifled with gradually moving up for blocking The plugging action of plug, to further ensure the closing effect to intake tunnel.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention Art scheme is modified or replaced equivalently, and without departing from the objective and range of technical solution of the present invention, should all be covered at this In the scope of the claims of invention.
