Abstract
The utility model provides a channel-water and sand-proof device for multi-silt river which is especially suitable for the channel-water and sand-proofing of rivers of variable water level and bed. The structure of the channel-water sand-proof device for multi-silt river is composed of rubber bags, fixed blocks, water inlet and outlet pipes, an exhaust pipe, a water pump, a valve, a water storage tank, etc. The rubber bags are anchored on the fixed blocks, and both are transversely arranged on the bottom of the entrance of the diversion canal of the river. The water pump and the water inlet and outlet pipes enable the rubber bag and the water storage tank communicated mutually. The elevating height of the rubber bag can be adjusted by starting the water pump, and the surface water body with a low silt content can flow over the top of the bag and flow into the diversion canal. The utility model has the advantages of simple structure, easy installation and good water diversion and sand-proof effect.
Description
The utility model relates to a kind of fully-loaded stream water diversion and sand control device, in particular for becoming the water diversion and sand control in water level, change bottom river.
At present, the channel of approach in many rivers is many owing to the water source contains silt, and service time, length was just silted up by silt, hindered water delivery, for this reason, need organize large quantities of labours termly, dig the canal desilting, especially the serious Huanghe valley of silt, this problem is more outstanding, and this not only wastes a large amount of human and material resources, and has a strong impact on agricultural production, increase agriculture cost, also caused the desertification of land of channel both sides.Also not have at present the fully-loaded stream of method solution preferably channel of approach sand prevention, subtract the silt problem.
The purpose of this utility model provides a kind of water diversion and sand control device that is used for fully-loaded stream, to solve the problem that channel of approach is silted up by silt.
The purpose of this utility model realizes in the following manner, promptly being provided with one in the channel of approach mouth bottom transverse of fully-loaded stream can be according to the variation of river water level, bottom and the rubber bag of lifting, the bottom water body that the river course sand content is high blocks, make the low surface water of sand content cover bag top and flow to channel of approach, reduce quantity of sand and mud into canal with this.
Figure of description 1 is a structural representation of the present utility model.
Figure of description 2 is a use schematic diagram of the present utility model.
With reference to Figure of description water diversion and sand control bag of the present utility model is put and to be known clearly Carefully describe.
Channel-water sand-proof device for multi-silt river of the present utility model is mainly by rubber bag (1), fixed block (6), and blast pipe (4), water inlet pipe and water outlet pipe (5), water pump (7), ball formula safety valve (14), gate valve (15) and water storage tank (8) etc. partly form. Rubber bag (1) is anchored on the fixed block (6), and both laterally are placed in the bottom of flume mouth, and water pump (7) and water inlet pipe and water outlet pipe (5) communicate rubber bag (1) and water storage tank (8). Fixed block (6) is to make with the cement system of giving or steel plate, and its cross section is the Jiong type, and Open Side Down, and the hole that centre and side have water inlet pipe and water outlet pipe (5) to pass reaches fixedly anchor bolt (16) and the metal link (13) of rubber bag (1).
Rubber bag (1) is anchored on the plane of fixed block (6), top and bottom at bag, be provided with Jiao Kou (2) and (3) that stack (4) and water inlet pipe and water outlet pipe (5) are installed, there is the glue ring (11) of rope (12) side, and an end bolt of rope (12) is solid on glue ring (11), and other end bolt is solid on metal link (13), this haulage gear has strengthened the orthostatic of rubber bag (1), after making it be full of water,, help stoping sand grain to cover the bag top near the garden cylindricality.
Stack (4) lower end is installed on the Jiao Kou (2) at rubber bag (1) top; ball formula safety valve (14) is installed on stack (4) top; this valve action is: rubber bag (1) is to open in exhaust condition; on rubber bag, press the silt state to close; when the hydraulic pressure in the rubber bag surpasses authorized pressure; water extrudes stack with the ball in the valve, and the rubber water-in-bag also overflows simultaneously, thereby plays the effect of protection rubber bag.Water inlet pipe and water outlet pipe (5) one ends are installed on the Jiao Kou (3) of rubber bag (1) bottom, and the other end communicates through water pump (7) gate valve (15) and water storage tank (8), and water storage tank (8) is placed on the channel of approach bank (10).
Embodiment:
Water diversion and sand control device of the present utility model is installed in channel of approach mouth place, river, during use, starts water pump, open gate valve, with the clear water injection rubber bag of water storage tank, the gas in the rubber bag is discharged by stack, behind the water-filling, the rubber bag top is lower than channel of approach water surface certain altitude.Because the sand content of river surface water is few, the sand content of bottom water body is big, and the downstream, river course is blocked and be discharged into to rubber bag with the bottom water body, introduces in the canal and surface water is covered the bag top.
The adjustable height of rubber bag can be regulated according to the variation of river level and bottom.When river level or bottom reduction, open water pump the part water in the rubber bag is extracted out, to reduce a bag heights of roofs; When river level or bottom rising, then start water pump water-filling in rubber bag, to improve a bag heights of roofs; When being pressed with silt on the rubber bag, then close the gate valve on the water inlet pipe and water outlet pipe, ball formula safety valve cuts out automatically, and rubber bag and pipeline are in closed state, and water body can not be forced out; When hydraulic pressure in the rubber bag too much surpassed authorized pressure because of pressing silt too much or because of water-filling, ball formula safety valve was opened, and water overflows from stack, thereby has guaranteed the safety of rubber bag.
Water diversion and sand control device of the present utility model, simple in structure, easy operating, cheap, dustproof effect is good, uses this device not compare than not using, can reduce and draw husky amount 30-50%, thereby significantly reduce the desilting amount of channel, have very high economic and social benefit.
