Abstract

The utility model discloses a hydropower-machinery integrated sand discharge device that comprises a siphonic sandline. The head end of the siphonic sandline is provided with a sand sucker and the tail end of the siphonic sandline is fixed on a rest pier arranged on a dam. A coffer is arranged on the sand sucker. The coffer is connected with a tugboat on water surface by a wire rope, thus facilitating movement. In addition, the coffer is provided with an intake pipe and a drain pipe. The control valve of the intake pipe and the drain pipe is arranged on the tugboat. The air intake pipe is communicated with pressure air source and water source in a conversion way respectively, thus facilitating the aeration or the water flow-through of the air intake pipe. The sand sucker is provided with a plurality of sand sucking nozzles. The ends of the sand sucking nozzles are sealed. The side wall of the sand sucking nozzles is provided with a plurality of sand sucking holes. The hydropower-machinery integrated sand discharge device makes use of a brand-new sand discharge concept to combine the hydropower and the machinery together, thus changing the modes of picking (sucking) sand and transporting sand by the machinery only or transporting sand by hydropower only before. As natural force (hydropower) is used for transporting sand, energy consumption is lower and the efficiency of sand transportation is high, thus having good social benefit and economical benefit.

Description

Hydraulic-mechanical integrated sand discharge apparatus

One, technical field:

The utility model relates to a kind of sand discharge apparatus, particularly relates to a kind of hydraulic-mechanical integrated sand discharge apparatus.

Two, background technology:

At present, the husky technology of the row that adopt in reservoir, river course or navigation channel has two classes: the one, and machinery digs sand: dredge boat disposes various mud-sucking devices, the husky mode of this row need external energy with slurry transportation to assigned address, then to pay sizable cost for the big reservoir deposits of siltation volume and just can achieve the goal.Another kind is a hydraulic transport of sediment: the characteristic of utilizing sediment movement is discharged by the husky hole of row before silt is delivered to sediment ejection opening again, though the husky mode of this row is to utilize hydraulic transport of sediment, do not need to expend external energy, but silt must be transported in the funnel scope before the sediment ejection opening, it could be delivered to the reservoir downstream, because the front-seat hourglass bucket body of reservoir dam is long-pending limited, it is not high often to arrange husky efficient.

Three, the content of utility model:

Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of simple in structure, easy to operate, do not need external energy, row husky efficient height and the little hydraulic-mechanical integrated sand discharge apparatus of energy consumption.

The technical solution of the utility model is:

A kind of hydraulic-mechanical integrated sand discharge apparatus, contain hydrocone type sandline and floating drum, the head end of described hydrocone type sandline is equipped with sandsucker, is fixed with caisson on this sandsucker, and described caisson is connected with the towboat of the water surface by wirerope, be convenient to move, and described caisson is provided with air inlet pipe and gutter, and the control valve of this air inlet pipe and gutter is arranged on the towboat, described air inlet pipe respectively with pressure gas source and water source conversion connection, be convenient in air inlet pipe ventilation or water flowing.

Described sandsucker contains a plurality of suction sand tube mouths, and a plurality of suction sand tube mouths are distributed in different directions.

The end sealing of described suction sand tube mouth, its sidewall is provided with the husky hole of a plurality of suctions.

The beneficial effects of the utility model are:

1, the brand-new husky theory of row of the utility model utilization, waterpower and machinery are combined cleverly, change the pattern that simple mechanical is before this dug (suction) sand and sediment transport or simple hydraulic transport of sediment, mainly utilize natural force (waterpower) sediment transport, little, sediment transport efficient height consumes energy.

2, sandsucker of the present utility model contains a plurality of suction sand tube mouths, and a plurality of suction sand tube mouths are distributed in different directions, and all inhale the end sealing of sand tube mouth, and its sidewall is provided with the husky hole of a plurality of suctions, such mechanism prevents the silting of silt effectively, thereby sediment transport efficient height.

3, the utility model adopts caisson to drive sandsucker to move up and down, and it is easy to operate, be convenient to control, uses very convenient.

4, the utility model towboat power is little, and the lifting of sandsucker realizes that by the draining of filling of caisson towboat only drives soil-suction head and shifts one's position, in addition, silt is carried by natural force, and the energy that sediment is crossed the dam is provided by the head difference of reservoir upstream and downstream, need not external energy, thereby energy consumption is little.

5, the utility model is arranged husky efficient height, and as calculated and with reference to pertinent literature, it arranges husky efficient can reach 300kg/m ³More than.

6, the utility model is applied widely, and simple in structure, cost is lower, is easy to promote, and has good society and economic benefit.

Four, description of drawings:

Fig. 1 is the structural representation of hydraulic-mechanical integrated sand discharge apparatus;

Fig. 2 is the vertical view of sandsucker shown in Figure 1.

Five, the specific embodiment:

Embodiment: referring to Fig. 1 and Fig. 2, among the figure, the head end of the hydrocone type sandline 4 of hydraulic-mechanical integrated sand discharge apparatus is equipped with sandsucker 2, is fixed with caisson 3 on this sandsucker 2, and caisson 3 is connected with the towboat 1 of the water surface by wirerope 10, be convenient to move, and caisson 3 is provided with air inlet pipe 9 and gutter 8, and the control valve of this air inlet pipe 9 and gutter 8 is arranged on the towboat 1, air inlet pipe 9 respectively with pressure gas source and water source conversion connection, be convenient in air inlet pipe 9 ventilation or water flowing.The tail end of hydrocone type sandline 4 is fixed on the buttress 7 that is provided with on the dam body 6.Buoyancy for the tail end that increases hydrocone type sandline 4 is fixed with floating drum 5 on the hydrocone type sandline 4 of dam body 6 inboards.

In order to prevent silting, sandsucker 2 is provided with five and inhales the sand tube mouth, inhales the sand tube mouth for five and is distributed on three directions, and inhale the end sealing of sand tube mouth, and its sidewall is provided with the husky hole of a plurality of suctions.

When row was husky, according to the concrete condition of different engineerings, the position, dam excessively of hydrocone type sandline 4 can be chosen in sluice, overfall dam or other position.Be selected in the syphon peak apart from the low position of the storehouse water surface, purpose is the vacuum that reduces the syphon peak as far as possible.Towboat 1 is simple and easy power ship, and its power can be arranged husky scale according to concrete engineering and decide.Should emit again being full of water in the hydrocone type sandline 4 in advance during initial launch, form syphon, rely on the pressure of water to carry out siphon row sand then.

When needs sandsucker 2 sinks under the water, open the valve water-filling in caisson 3 on the air inlet pipe 9, caisson 3 sinks.When needs promote sandsucker 2 and shift one's position, in caisson 9, inflate by air inlet pipe 9 with air pump, extrude water body by gutter 8, caisson 3 come-ups.The buoyancy that the lifting of caisson 3 produces by himself filling draining realizes that unless maintenance rises to outside the water surface or the bank, the proper height that only need be raised in service can make horizontal the moving of towboat drive get final product.

Rely on the pressure of water to carry out siphon by crossing building or passing through building row sand, change quantity, the quantity that changes floating drum of inhaling the sand tube mouth on the sandsucker and change caisson air inlet discharge structure and can form a plurality of embodiment, be common excursion of the present utility model, do not describe in detail one by one at this.
