Pump sluice gate and sluice gate station for urban rainfall flood regulation and storage

Abstract

The invention relates to a pump sluice gate for urban rainfall flood regulation. The pump sluice gate for urban rainfall flood regulation comprises a suspension type submerged pump unit and a gate plate, wherein a shaft is vertical; a submerged pump extends out of the lower end surface of the shaft; a hoisting component is fixedly arranged at the upper end of a shaft cover; the gate plate comprises two gate plate single bodies; the two gate plate single bodies are vertically and fixedly mounted on two sides of the shaft along the outer wall of the shaft; sealing assemblies are symmetrically arranged on two sides of the outer end of each of the two gate plate single bodies; limiting guiding blocks are arranged on one sides or two sides of the outer ends of two pump sluice gate single bodies; two pulley blocks are vertically and symmetrically mounted on the outer end surfaces of the two sluice gate single bodies; and sealing components are mounted on the lower end surfaces of the two gate plate single bodies and the shaft. The invention further provides a sluice gate station for urban rainfall flood regulation. The pump sluice gate and the sluice gate station for urban rainfall flood regulation have the advantages that the structural design is reasonable, mounting is facilitated, repair is flexible and is not affected by the outside, a large number of civil engineering investments are saved, the labor intensity is reduced, potential safety hazards are reduced, mounting and using of large or ultra-large sluice gates become possible, therefore, the designed range of the flow of the sluice gate is expanded, and the running efficiency of the device is improved.

Description

technical field [0001] The invention belongs to the technical field of water conservancy regulation and storage, in particular to a pump gate and a gate station for urban rainwater regulation and storage. Background technique [0002] At present, most of the pump gates used on the river are combined with the gate and the submersible tubular pump. The submersible tubular pump is horizontally and fixedly installed in the gate structure, and the submersible pump is also installed vertically in the steel shaft on one side of the gate. One side of the steel shaft is fixedly connected with the ram. The above two methods have the following defects: [0003] 1. When the water pump encounters a mechanical failure and needs to be eliminated, the hoist cannot lift the water pump alone; the pump gate must be lifted synchronously to realize equipment maintenance, which is not energy-saving. During maintenance, it is necessary to intercept the river (or add maintenance before and after) ...

AI Technical Summary

Problems solved by technology

[0003] 1. When the water pump encounters a mechanical failure and needs to be eliminated, the hoist cannot lift the water pump alone; the pump gate must be lifted synchronously to realize equipment maintenance, which is not energy-saving. During maintenance, it is necessary to intercept the river (or add maintenance before and after) gate) otherwise the maintenance work cannot be realized

[0004] 2. The horizontal installation structure of the submersible tubular flow pump will be transmitted by the ram due to the impact of the water flow and the vibration generated by the operation of the fuselage during actual operation, which will increase the load of the ram invisibly, resulting in a decrease in the service life of the ram; The horizontal installation structure of the submersible tubular pump or the coupling installation structure will produce partial load on the ram, which will also lead to a decrease in the service life of the ram; the horizontal installation structure of the submersible tubular pump can only lift the pump independently by driving. Using other lifting mechanisms can only complete the maintenance work by synchronously lifting the pump gate, and the limited selection of lifting equipment is not conducive to equipment maintenance;

[0005] 3. According to the installed capacity of a single water pump, conventional pump gates cannot be equipped with large-scale water pump units, so the selection range of pump gates is narrow, and the flow rate is limited when rainstorms must be forced to discharge; affecting production and life;

[0006] 4. Most of the conventional pump gates fix the hoist or hoist on the elevated load-bearing beam, and transmit the force to the pump gate for vertical lifting; the load-bearing beam is a fixed concrete structure or steel structure, which is arranged directly above the pump gate. , in practical applications, hydraulic hoist is also fixedly installed in the chute of the door frame on both sides of the pump gate, and the linear movement of the piston rod is used to realize the overall lifting of the pump gate. The overall and split inspection and maintenance of the pump gate are affected;

[0008] 6. In the landscape river, in order not to affect the view, the outer eaves of the buildings of the conventional pump gate hoist room often need to add a lot of decoration investment to achieve coordination and unity with the surrounding landscape; while for the pump gate on the non-landscape river , the exposed hoist and wire rod are often stolen, which affects the normal operation of the equipment;

[0009] In summary, conventional pump gates have defects such as low efficiency, large investment, no energy saving, no environmental protection, and potential safety hazards.
