Technical Field

The utility model belongs to the technical field of the gate seal and specifically relates to a quick sealing device of gate can be applied to power station dam and block water, diversion, building such as drainage (tailwater), irrigation and water conservancy diversion building, industrial water diversion building, various gates in artifical canal building, places such as reservoir, weir pond building.

Background

The method adopts rubber water stopping and the like in various gates in various forms, when the gate falls in place, because the water level difference between the front part of the gate and the rear part of the gate is small, the acting force of water on the gate in the closing direction is insufficient, and the sealing water stopping piece of the gate is not stressed, the gate has water leakage phenomenon, the water pumping and drainage of a construction site are not completed, the equipment maintenance and the building repair are seriously influenced, a newly-built and expanded construction site can be flooded by water, so more pumping and drainage equipment needs to be configured, a large amount of electric energy or oil and labor cost is consumed, the project energy consumption needing to stop water for a longer construction time is larger, a large extra burden is added to an enterprise, a large amount of labor and energy consumption cost is usually increased, the influence of water leakage on the construction period is larger, particularly, the rush repair project is more obvious, the rush repair period is prolonged, the related loss is larger, and even the whole plant can not recover the production, therefore, the gate is necessary to be sealed and leak-proof quickly.

Disclosure of Invention

The utility model aims to solve the technical problem that a quick sealing device of gate is provided can let the gate seal leak-stopping rapidly after the floodgate operation targets in place under the gate, avoids closing not tight because of the gate and leaks, avoids increasing manpower and electric energy or oil consumption cost because of the drainage, and the construction period such as reduction equipment overhauls, hydraulic structure restoration, extension wins more valuable time for whole factory or the normal production of partial region recovery.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:

a gate power-assisted quick sealing device comprises a sliding chute arranged behind a gate, wherein a power booster is arranged on the sliding chute in a matching manner, and the other end of the power booster is opposite to a gate groove; the booster is connected with a hydraulic source or a pneumatic source through a hose.

The sliding chutes are symmetrically arranged at the left and right behind the gate back, and the left sliding chute and the right sliding chute are at least one group.

The booster is a hydraulic cylinder or a pneumatic cylinder, and the piston stroke of the hydraulic cylinder or the pneumatic cylinder is 20mm-300 mm.

The booster passes through the backup pad and slides and set up in the spout and lock through the bolt.

And a return spring is arranged in the hydraulic cylinder or the pneumatic cylinder, is arranged in the upper cavity of the piston and is sleeved on the piston rod, one end of the return spring is opposite to the piston, and the other end of the return spring is opposite to the top of the upper cavity of the piston.

The utility model relates to a quick sealing booster unit of gate through set up behind the gate back of the body and hang the spout of booster and hang the locking mechanical system after, prevents that the booster roll-off from droing, can make the device dismantle reuse to other gates on. The piston is extended and jacked by utilizing an operation method of supplying pressure to the pressure source by utilizing the pneumatic cylinder piston or the lower cavity of the hydraulic cylinder piston, the action process of the piston is the same as that of a jack, the sealing surface of the gate can be quickly pressed, water leakage is avoided, and normal construction or equipment maintenance of a closed area can be guaranteed.

Detailed Description

As shown in fig. 2-9, a gate booster quick sealing device comprises sliding grooves 1 which are arranged on the back of a gate 9 and used for hanging a booster 2, wherein each sliding groove 1 is independent, the sliding grooves 1 are sealed in three parts, and an opening at the upper part is convenient for hanging the booster 2. A locking bolt is established to 1 top entry of every spout, treats that booster inserts behind the spout 1 with this bolt fastening booster 2, prevents that booster 2 from following 1 entrance roll-off of spout and droing when gate 9 puts down. The booster 2 can be selected from a hydraulic cylinder or an air cylinder. The hydraulic cylinder or the air cylinder comprises a cylinder body 8 and a piston rod 7, wherein one end of a return spring 6 is connected with the piston rod 7, and the other end of the return spring is connected with the cylinder body 8. The lower cavity of the cylinder body 8 is provided with an oil inlet or an air inlet which is communicated with the pressure-resistant hose 4, and the pressure-resistant hose 4 is connected with a pressure source.

The length of the piston stroke of the booster is selected according to the distance between the back of the gate and the gate slot, and is generally between 20mm and 300 mm. The number of the boosters can be determined to be 2 or 4 or more according to the height of the gate and the field environment, and the boosters are symmetrically arranged left and right. When the booster 2 is hung on the sliding chute 1 behind the gate 9, the top of the booster is opposite to the gate slot 3 and forms 90 ℃ with the gate 9. When the gate 9 is lifted, firstly, the booster 2 is respectively hung on the sliding chutes 1 and locked by bolts, then the pressure-resistant hose 4 is communicated with the lower cavity of the piston of the booster, and the other end of the pressure-resistant hose is connected with the hydraulic (pneumatic) source gate valve 11, then the gate 9 is put down and determined to be in place. The pressure source can be got in the factory nearby, also can support hand pump, transfers when gate 9 and puts in place the back, opens gate valve 11, and operation hand pump is with 2 piston jack-ups of booster, lets gate stagnant water spare 10 atress compress tightly, reaches the effect of quick sealed stagnant water. Then, the pressure source gate valve 11 is closed to prevent the pressure from being released in a reverse direction. When the gate 9 needs to be lifted, the pressure source gate valve 11 is firstly opened, the pressure in the piston cavity of the booster 2 is released back to the hand pump, and meanwhile, the piston is reset under the action of the spring force of the built-in reset spring 6, and the gate 9 can be lifted by operation after the piston is reset in place. The booster 2 can then be removed for further shutter operations.

The sliding grooves 1 are arranged left and right behind the gate, are symmetrical left and right, are independent, and meet the condition of hanging 1 booster.
