Description
Technical field
The utility model relates to a kind of variable-volume type multi-chamber fire water pump for use in forest, belongs to fire-fighting domain.
Background technique
" with above-water method " is the trend of Forest Fires technological means development, and forest fire prevention and control pump occupies very important status as realization with the visual plant of above-water method.Forest fire prevention and control pump because field water resource is not available anywhere, often needs long distance water transfer, so should possess desirable lift and flow.Meanwhile, forest fire prevention and control pump is mostly carried by fire fighter and enters forest zone, thus should lightweight as far as possible, volume is little so that carry.And China's forest fire prevention and control pump adopts city and industrial and mineral fire water pump mostly, have that lift is low, size and weight is not easy to problems such as carrying, can not forest fire prevention and control be advantageously applied to.Therefore, the forest fire prevention and control dedicated pump tool of research development adaptation China forest zone truth is of great significance.
Model utility content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of variable-volume type multi-chamber fire water pump for use in forest, internal rotor is driven to rotate by main axis, thus drive external rotor to rotate, what external rotor rotation replaced makes the volume of the first separate chamber and the second separate chamber minimum by being up to, arrive maximum again, water outlet efficiency is high.
Technological scheme: for solving the problems of the technologies described above, a kind of variable-volume type multi-chamber fire water pump for use in forest of the present utility model, comprise the pump housing, the described pump housing is provided with pump chamber, the main shaft being positioned at pump chamber center is installed in pump chamber, main shaft is installed the internal rotor being provided with some external tooths, internal rotor is provided with the external rotor engaged with external tooth, external rotor eccentric setting, the external frame of external rotor waits the evagination circular arc of radian to form by three sections, any two sections of evagination arcs intersect are in an intersection point, in the process of rotor turns outside, any time, external rotor had at least an intersection point to be positioned on the chamber wall of pump chamber, pump chamber is divided into the first separate chamber and the second separate chamber by external rotor, first separate chamber is provided with the first water intake and the first water outlet, second separate chamber is provided with the second water intake and the second water outlet, first water intake and the second water outlet are positioned at the same side, second water intake and the first water outlet are positioned at the same side.
As preferably, the shape of the cross section of described pump chamber is made up of with two semicircles be connected with rectangle a rectangle.
As preferably, every section of circular arc of the external frame of described external rotor is provided with groove.
A kind of variable-volume type multi-chamber fire water pump for use in forest group, comprise the variable-volume type multi-chamber fire water pump for use in forest that several are above-mentioned, the first water outlet of several variable-volume type multi-chamber fire water pump for use in forests is all communicated with total outlet pipe with the second water outlet.
Beneficial effect: variable-volume type multi-chamber fire water pump for use in forest of the present utility model, internal rotor is driven to rotate by main axis, thus drive external rotor to rotate, time external rotor rotates, external frame makes the volume of the first separate chamber minimum by being up to, water extrudes away from the first water outlet, simultaneously the second separate chamber volume by minimum to maximum, water enters the second separate chamber from the second water intake, then the first separate chamber volume by minimum to maximum, first separate chamber water inlet, second separate chamber smaller volume simultaneously, compressing water sprays from the second water outlet, in same process, first separate chamber or the second separate chamber are outwards sprayed water, efficiency of drawing water is high, and due to the squeezing action of external frame, irrigation pressure is large, lift is high.
Accompanying drawing explanation
