Abstract
The utility model discloses stem flow cut-off equipment. A drainage tube of the existing stem flow cut-off equipment with a simple structure is a soft tube, so that the existing stem flow cut-off equipment easily deforms, is poor in cut-off effect, needs to be frequently replaced, and leads to the situation that the drainage amount is smaller than the stem flow rate caused by deformation of the soft tube especially when the rainfall is large, so as to affect the accuracy of data. The stem flow cut-off equipment comprises a polyurethane foam body (1), wherein a trunk hole is formed in the middle of the polyurethane foam body, and includes a top end and a bottom end; the bottom end is a plane; the top end is a curve surface; the curve surface is connected with a hard material tube (2); the hard material tube passes through the polyurethane foam body to extend to the trunk. The stem flow cut-off equipment is used for cut-off of the trunk.
Description
Technical field
the utility model relates to a kind of trunk runoff cut-off equipment.
Background technology
the existing device dammed for trunk is all that the equipment by more complicated carries out mostly, and cost is higher, and is arranged on field for a long time, and also shorter through the life-span of wind and weather, cost of investment is very high.
the drainage tube of existing trunk runoff cut-off equipment relatively simple for structure is software tubing, easily produces distortion, and the effect of damming is bad, need often to change, particularly when rainfall is bigger than normal, due to the flexible pipe distortion, cause drainage flow to be less than water flow in the stem, affect the accuracy of data.
Summary of the invention
the purpose of this utility model is to provide a kind of trunk runoff cut-off equipment.
described purpose is achieved by the following scheme:
a kind of trunk runoff cut-off equipment, its composition comprises: urethane foam, described urethane foam centre position has trunk hole, described trunk hole has top and low side, described low side is plane, described top is curved surface, and described curved surface connects the hard material pipe, and described hard material pipe extends to trunk through urethane foam.
described trunk runoff cut-off equipment, described curved surface comprises front bevel and back bevel, the high-end large inclined-plane, left side that is connected of described front bevel and described back bevel, described front bevel is connected little inclined-plane, right side with the bottom of described back bevel, described hard material pipe is equipped with in the bottom on little inclined-plane, described right side and the junction of described front bevel and described back bevel.
described trunk runoff cut-off equipment, described curved surface comprises frontal plane and back plane, the high-end large inclined-plane, left side that is connected of described frontal plane and described back plane, described frontal plane is connected little inclined-plane, right side with the bottom of described back plane, described hard material pipe is equipped with in the bottom on little inclined-plane, described right side and the junction of described front bevel and described back bevel.
The beneficial effects of the utility model are:
the hard material pipe range phase that the utility model adopts stay field indeformable, do not affect use, needn't often change, reduced use cost.
the utility model urethane foam is soft material, and itself has sealing property, can tightly with trunk, combine, and has stoped any trickling of the liquid on the trunk.
front bevel and back bevel that the utility model adopts can guarantee that the liquid on trunk trickles along projected route, then flow into the hard material pipe, along the hard material pipe, flow out, and making does not have liquid to retain between trunk and urethane foam.
The accompanying drawing explanation
accompanying drawing 1 is the structural representation that the utlity model has front bevel and back bevel.
accompanying drawing 2 is the structural representations that the utlity model has frontal plane and back plane.
Embodiment
elaborate the utility model preferred embodiment below in conjunction with accompanying drawing.
embodiment mono-
a kind of trunk runoff cut-off equipment, as shown in accompanying drawing 1, accompanying drawing 2, its composition comprises: urethane foam 1, described urethane foam centre position has trunk hole, described trunk hole has top and low side, and described low side is plane, and described top is curved surface, described curved surface connects hard material pipe 2, and described hard material pipe extends to trunk through urethane foam.
one end of trunk hole is disconnected and being enclosed within on trunk, the circumferential length of trunk hole is less than the circumferential length of trunk, be enclosed within urethane foam on trunk combining with trunk tightly, block the trickling of the liquid on trunk, liquid on trunk is trickled along the curved surface in urethane foam, finally flow in the hard material pipe.The hard material pipe is iron pipe or plastic conduit or weldless steel tube or compo pipe.
embodiment bis-
the difference of the present embodiment and embodiment mono-is, as shown in Figure 1, described trunk runoff cut-off equipment, described curved surface comprises front bevel 3 and back bevel, the high-end large inclined-plane 4, left side that is connected of described front bevel and described back bevel, described front bevel is connected little inclined-plane 5, right side with the bottom of described back bevel, described hard material pipe is equipped with in the bottom on little inclined-plane, described right side and the junction of described front bevel and described back bevel.Described front bevel is 1:5 with the gradient ratio of described back bevel; The gradient on large inclined-plane, described left side is than being 1:8; The gradient on little inclined-plane, described right side is than being 1:18.
the liquid trickled on trunk flows on front bevel and back bevel along large inclined-plane, left side, then flows to the bottom of front bevel and back bevel, flows into the hard material pipe.
embodiment tri-
the difference of the present embodiment and embodiment mono-is, as shown in Figure 2, described trunk runoff cut-off equipment, described curved surface comprises frontal plane 6 and back plane, the high-end large inclined-plane, left side that is connected of described frontal plane and described back plane, described frontal plane is connected little inclined-plane, right side with the bottom of described back plane, described hard material pipe is equipped with in the bottom on little inclined-plane, described right side and the junction of described front bevel and described back bevel.
present embodiment is the exemplary illustration of this patent not to be limited to its protection domain; those skilled in the art can also carry out part to it and change; as long as no the Spirit Essence that exceeds this patent, all be considered as the replacement that is equal to this patent, all within the protection domain of this patent.
