Detailed description of the invention
Below embodiment of the present utility model is elaborated; the present embodiment is implemented under premised on technical solutions of the utility model; give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Embodiment 1
As depicted in figs. 1 and 2, the present embodiment comprises: the single bend pipe 1 be rotationally connected successively, revolving bed 3 and twin elbow 2, wherein: single bend pipe 1, be arranged at rolling element 4 between single bend pipe 1 inwall and revolving bed 3 and revolving bed 3 forms the first revolute pair, twin elbow 2, be arranged at rolling element 4 between twin elbow 2 outer wall and revolving bed 3 and revolving bed 3 forms the second revolute pair, thus realize pitching and the revolution of fire monitor.
In the present embodiment, the entrance point of described single bend pipe 1 is connected with upstream, and the port of export of single bend pipe 1 connects the entrance point of revolving bed 3, and the port of export of twin elbow 2 is provided with screw thread for connecting fire monitor nozzle or flange.
The first described revolute pair, the second revolute pair by two independently power source drivings, also can be driven by transmission mechanism by a power source simultaneously.
In different occasions, described rolling element 4 also can be arranged between single bend pipe 1 outer wall and revolving bed 3, be arranged between twin elbow 2 inwall and revolving bed 3, thus forms corresponding two revolute pairs.
Described single bend pipe 1, revolving bed 3 and twin elbow 2 are provided with bullet groove 6 and are formed raceway after combining, and realize the rolling of rolling element.
As shown in Figure 3, the inlet axis EG of described single bend pipe 1 and outlet axes FG intersects at G point, and the angle (acute angle) of EG and FG is λ;
As shown in Figure 4, described twin elbow 2 is S shape structure, its inlet axis AP and outlet axes OBA intersects at A point, and the angle (acute angle) of axis AP and axes O BA is β, and the central axis PB of changeover portion 5 and the angle (acute angle) of outlet axes OBA are α;
Described changeover portion 5 is the arc pipe of radius R, is provided with the arc transition that radius is R between changeover portion and the port of export.
As shown in Figure 5, the inlet axis CQ of described revolving bed 3 and the angle (acute angle) of outlet axes DQ are γ;
Above-mentioned axis is generally understood as central symmetry axis according to this area.
As shown in Fig. 3 ~ Fig. 5, the inlet axis AP of twin elbow 2 and the angle of outlet axes OBA equal the inlet axis of revolving bed 3 and the angle of outlet axes, i.e. β=γ; The advantage of such design is: after said apparatus assembling, A point on twin elbow 2 overlaps with the Q point on revolving bed 3, provides condition for the outlet axes OBA of twin elbow 2 is in plane that the inlet axis EG of described single bend pipe 1 and outlet axes FG forms.
Under preferable case, the inlet axis AP of twin elbow 2 and the angle of outlet axes OBA equal the half of the inlet axis EG of single bend pipe 1 and the angle of outlet axes FG, namely
the advantage of such design is: make the value at λ, β, γ tri-angles minimum, on the one hand can reduce volume, weight reduction, on the other hand can optimizing flow passage, makes the overcurrent loss reduction of extinguishing chemical in runner.
The inwall section of the single bend pipe 1 in the present embodiment, revolving bed 3 and twin elbow 2 is preferably circular, but also can adopt different special shapes in other occasions.These shapes are preferably centrosymmetric geometric figure so that composition revolute pair.
As shown in Figure 1, for the state that the fire monitor port of export elevation angle is minimum, in conjunction with above-mentioned definition, now β, γ are consistent for the effect at the elevation angle with λ for the effect at the elevation angle, in order to make the conclusion of this technical scheme, there is versatility, might as well suppose that single bend pipe 1 direction EG of intaking is direction, 90 °, the elevation angle, therefore, now fire-fighting gun elevation is: 90 ° of-λ-(β+γ).
As shown in Figure 2, for the state that the fire monitor port of export elevation angle is maximum, in conjunction with above-mentioned definition, now β, γ are contrary for the effect at the elevation angle with λ for the effect at the elevation angle, single bend pipe 1 direction EG of intaking is direction, 90 °, the elevation angle, therefore, now fire-fighting gun elevation is: 90 ° of-λ+(β+γ).
Under these conditions, assembling and setting fire monitor initial attitude is as shown in Fig. 1 or 5, the driving of the first rotary pair, the second revolute pair adopts linked manner (such as gear drive or electric-linked), the consecutive variations at the fire monitor elevation angle can be realized, and under the state of the elevation angle, the outlet axes OBA of described twin elbow 2 can be in the plane that the inlet axis EG of described single bend pipe 1 and outlet axes FG forms.
