Abstract

The utility model provides a novel pump floodgate of bottom seal structure, includes the headstock gear, concrete river bottom surface, the sluice sealing strip, the immersible pump, the sluice mounting groove, the sluice is installed in the sluice mounting groove, installs the sluice sealing strip on the sluice mounting groove, installs the immersible pump on the sluice, the sluice bottom is concrete river bottom surface, the sluice is driven by the headstock gear, the characteristic: the bottom surface of the concrete river channel at the water gate installation groove is provided with an inclined plane, and the bottom of the water gate is an inclined plane matched with the inclined plane at the bottom of the concrete river channel. The inclination angle of the bottom surface of the concrete river channel is 15 degrees. The advantage is the river course bottom surface all changes the inclined plane into, because the factor of rivers, influences the sealed silt, metal block, stone etc. of sluice and river course bottom surface and is difficult to gather on this inclined plane. Owing to adopt the inclined plane, the sluice can be along sealed inclined plane gliding under the condition of dead weight when the closing condition, and the sluice further compresses tightly the sluice sealing strip in the sluice mounting groove, makes the sealed effect in both sides of sluice better.

Description

Novel pump brake with bottom sealing structure

Technical Field

The utility model relates to a novel bottom seal structure's pump floodgate.

Background

Due to the need of flood control and water replenishment, a pump gate system for controlling the water level of a river channel is often built in the river channel in urban rivers, as shown in fig. 1. In order to ensure that the water level of the inland river is kept stable, the gate is in a closed state. The water level of the inland river is suddenly increased due to rainstorm and other reasons, when the water level of the inland river is higher than the water level of the foreign river, the winch hoist is started, the gate is opened, and the water in the inland river automatically flows to the foreign river; when the water level in the inland river is lower than that in the foreign river, the horizontal submersible pump installed on the gate is started to operate, water in the inland river is forcibly discharged to the foreign river, and the water level in the inland river is guaranteed to be kept normal. Due to drought and other reasons, the water level of the inland river is reduced, and water needs to be supplemented from the inland river. When the water level of the inland river is lower than that of the foreign river, starting the winch hoist, opening the gate, and automatically flowing the water in the foreign river to the inland river; when the water level in the inland river is higher than that in the inland river, the horizontal submersible pump installed on the gate is started to rotate reversely, water in the inland river is forcibly discharged to the inland river, and the water level in the inland river is guaranteed to be kept normal. The bottom surface of the river channel of the pump station system with the structure is usually of a horizontal concrete structure. After the sluice is opened, because the river bottom surface of the sealing part of the sluice and the river bottom surface adopts a horizontal structure, the part is often accumulated with some metal blocks, stones and the like. When the sluice is closed once more, the sluice can be withstood to the river course bottom surface metal block, stone etc. of gathering at the sealing part of sluice and river course bottom surface, leads to sluice and river course bottom surface not fine sealed to cause and can not fine stagnant water of sluice. Improvements are therefore desired.

Disclosure of Invention

The utility model aims at solving among the prior art river course pump floodgate system because the watercourse bottom surface of the sealing part of sluice and river course bottom surface has adopted horizontal structure to seal the plane billet, the above-mentioned problem that P type seal exists is installed to sluice side and bottom, provides a novel bottom seal structure's pump floodgate. The utility model relates to a novel pump floodgate of bottom seal structure, including hoist headstock gear, concrete river bottom surface, sluice sealing strip, immersible pump, sluice mounting groove, sluice are installed in the sluice mounting groove, install the immersible pump on the sluice floodgate secret sluice on the sluice mounting groove, and the sluice bottom is concrete river bottom surface, and the sluice is driven its characterized in that by the headstock gear: the bottom surface of the concrete river channel at the water gate installation groove is provided with an inclined plane, and the bottom of the water gate is an inclined plane matched with the inclined plane at the bottom of the concrete river channel. The inclination angle of the bottom surface of the concrete river channel is 15 degrees. The utility model has the advantages that the river course bottom surface all changes the inclined plane into, because the factor of rivers, influences water floodgate and the sealed silt, metal block, stone etc. of river course bottom surface and be difficult to gather on this inclined plane. And because the sealing part of sluice and river course bottom surface adopts the inclined plane, the sluice can slide down along sealed inclined plane under the condition of dead weight when the sluice is at the closure state, and the sluice further compresses tightly the sluice sealing strip in the sluice mounting groove, makes the sealed effect of both sides of sluice better.

Drawings

fig. 2 is a schematic structural diagram of the present invention.

Detailed Description

In the figure, a novel pump gate with a bottom sealing structure comprises a winch hoist 1, a concrete river bottom surface 2, a water gate sealing strip 3, a submersible pump 4, a water gate 5, a water gate mounting groove 6, wherein the water gate is mounted in the water gate mounting groove, the water gate sealing strip 3 is mounted on the water gate mounting groove, the submersible pump is mounted on the water gate, the bottom of the water gate is the concrete river bottom surface, and the water gate is driven by the hoist, and the pump gate is characterized in that: the bottom surface of the concrete river channel at the water gate installation groove is provided with an inclined plane, and the bottom of the water gate is an inclined plane matched with the inclined plane at the bottom of the concrete river channel. The inclination angle of the bottom surface of the concrete river channel is 15 degrees. Due to the factors of water flow, silt, metal blocks, stones and the like which affect the sealing of the sluice and the bottom surface of the river channel are not easy to accumulate on the inclined surface. And because the sealing part of sluice and river course bottom surface adopts the inclined plane, the sluice can slide down along sealed inclined plane under the condition of dead weight when the sluice is at the closure state, and the sluice further compresses tightly the sluice sealing strip in the sluice mounting groove, makes the sealed effect of both sides of sluice better.
