Abstract
The utility model relates to a water discharging device without valves, which is used for small-sized water storage projects. A water discharging hose is connected with a water discharging pipe at the lower part of an existing small-sized water storage project, and an upper end opening of the hose extends out of the water surface, and is connected with a pull rope. The upper end opening of the hose is provided with a filtering net, and is connected with a float; the hose is made of plastic material or rubbery material, or is made of a metal snake skin hose. The length of the hose is preferred to be higher than the water surface. When water is not discharged, the hose is pulled up, and the opening of the hose is fixed above the inside water surface to ensure that no water is stored in the hose and the water discharging pipe so that the pipes are prevented from being frozen cracked in winter. When water is discharged, the opening of the hose is put into water, and the float of the opening of the hose makes the opening of the hose in a position about 20 centimeters below the water surface to ensure that clean fresh warm water at the water surface is discharged from the water discharging pipe. Not only can the pipes be blocked, but also crop irrigation is benefited. The utility model has the advantages of simple structure and convenient use; the pipes can not be blocked, frozen cracked or damaged; discharged water is favorable for crop irrigation.
Description
Technical field
The utility model relates to the small-sized water storage project technical field that discharges water, and belongs to a kind of no gate valve jettison gear.
Background technology
At present, little reservoir, dyke, dam etc. retained in the engineering, generally all in the adjutage outer end of dam body bottom gate valve is installed and discharged water, and reservoir, water cellar are generally all repaiied the gate valve well outside (cellar for storing things) in the pond, gate valve is installed is discharged water.There is following shortcoming in this mode of discharging water: (1), can not be antifreeze effectively in winter, and cause the gate valve bursting by freezing to damage and leak; (2) because gate valve is in engineering bottom or Lower Half, when in river channel sedimentation or the pond precipitation being arranged, gate valve is blocked, and can not discharge water: (3), are difficult for changing because gate valve directly is connected with adjutage after gate valve damages; When (4) gate valve discharges water, water is emitted by engineering bottom or Lower Half, contains sand in the water, contains mud and water temperature is low, contains sand and contains mud and how to cause the field pipeline blockage easily, and, water temperature is hanged down and is difficult for plant growth: because the water inlet of adjutage is lower, pressure is bigger, blocks not easy-clear of impurity that dirty facility blocks: after (6) gate valve is closed (5), there is not replenish air in the water pipe, after end discharges water, form negative pressure in the water pipe, blow-off line is wrecked.
Summary of the invention
The purpose of this utility model provides a kind of no gate valve jettison gear, the shortcoming that it is simple in structure, easy to use, as can to avoid existing gate valve to discharge water and exist.
For achieving the above object, the utility model is taked following design scheme:
A kind of no gate valve jettison gear that is used on the small-sized water storage project, it is characterized in that: be connected with the flexible pipe that discharges water on the adjutage of existing small-sized water storage project bottom, the upper port of this flexible pipe is stretched out the water surface, is connected with stay cord at the upper port place of flexible pipe.
Upper port place at flexible pipe is provided with screen pack, can prevent that drifts such as leaf from entering in the hose port.
Being connected with cursory, cursory effect in described flexible pipe upper end is that hose port is in the certain distance in water surface below.
Described flexible pipe is to make with plastic material or elastomeric material, or adopts the metallic snakeskin flexible pipe to make.The length of flexible pipe is advisable to surpass the water surface, and pull-up when not discharging water is fixed on the mouth of pipe more than the inboard water surface, and making in flexible pipe and the adjutage not can water, avoids pipeline bursting by freezing in winter; When discharging water the mouth of pipe is put into water, the mouth of pipe cursory makes the mouth of pipe be in following about 20 centimetres of the water surface, and the clean clear warm water at water surface place is emitted from adjutage, neither can blocking pipeline, be beneficial to crop irrigation again.
The utility model has the advantages that: simple in structure, easy to use, pipeline can not stop up, bursting by freezing, damage phenomenon take place, and the water of emitting helps crop irrigation.

The specific embodiment
Referring to shown in Figure 1: a kind of no gate valve jettison gear that is used on the small-sized water storage project, it is connected with the flexible pipe 5 that discharges water on the adjutage 7 of existing small-sized water storage project 6 bottoms, the upper port 3 of this flexible pipe 5 is stretched out the water surface, is connected with stay cord 4 at upper port 3 places of flexible pipe 5.
Upper port place at flexible pipe 5 is provided with screen pack 2, can prevent that drifts such as leaf from entering in the flexible pipe port 3.
It is cursory 1 to be connected with in described flexible pipe 5 upper ends, and cursory 1 effect is that flexible pipe port 3 is in about 20 centimetres of water surface belows.
Described flexible pipe 5 is to make with plastic material or elastomeric material, or adopts the metallic snakeskin flexible pipe to make.The length of flexible pipe is advisable to surpass the water surface, and pull-up when not discharging water is fixed on pipe port 3 more than the inboard water surface, and making in flexible pipe 5 and the adjutage 7 not can water, avoids pipeline bursting by freezing in winter; When discharging water pipe port 3 is put into water, cursory 1 of the mouth of pipe makes the mouth of pipe be in following about 20 centimetres of the water surface, and the clean clear warm water at water surface place is emitted from adjutage 7, neither can blocking pipeline, be beneficial to crop irrigation again.
When engineering adjutage diameter is big, can several tee pieces be installed on adjutage, adjutage is installed on tee piece again.
