Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy projects, and in particular relates to a cap-type surface water intake with remote control for small and medium-sized reservoirs. Background Art

[0002] In order to meet the needs of environmental protection and downstream agricultural irrigation, many small and medium-sized reservoirs need to take water in layers.

[0003] Because water in a reservoir may form layers of varying densities due to variations in temperature, salinity, and dissolved oxygen, stratified water extraction can reduce disturbance and mixing of the water, thereby protecting aquatic ecosystems while ensuring the quality and supply of agricultural irrigation water. Furthermore, stratified water extraction can avoid collecting floating debris from the surface water.

[0004] Conventional stratified water intake designs primarily utilize stratified intake towers or stoplog gates. However, stratified intake towers are tall, with concrete chambers, requiring high foundation geological conditions and often requiring significant engineering effort and investment. Stoplog gates, on the other hand, are shore-tower intakes installed on the reservoir shore, utilizing stoplog gates to draw water in stratified layers. To accommodate water level fluctuations, the intake towers are also designed to be tall, placing high demands on foundations. These often result in poor tower stability, making installation difficult or requiring high foundation treatment costs. Therefore, small and medium-sized reservoirs with poor inlet foundations often lack the foundation conditions to utilize these two intake designs. Utility Model Content

[0005] In order to solve the technical problems in the design of stratified water intakes for small and medium-sized reservoirs, the present invention proposes a cap-type surface water intake with remote control.

[0006] A cap-type surface water intake with remote control is set at the water inlet of the reservoir water transfer tunnel, and is characterized by comprising a floating ball, an outer water intake casing, an inner water intake casing, a hydraulic cylinder and a remote-controlled electric hydraulic pump, wherein: a hydraulic cylinder is set below the floating ball, a piston rod of the hydraulic cylinder is connected to the floating ball, a cylinder barrel of the hydraulic cylinder is fixedly connected to the outer water intake casing, and a hydraulic port of the hydraulic cylinder is connected to the remote-controlled electric hydraulic pump;

[0007] An inner water intake casing is arranged inside the outer water intake casing, and the inner water intake casing is fixedly installed and communicated with the water delivery tunnel.

[0008] Specifically, a concrete base is provided outside the inner water intake casing, and the inner water intake casing is connected with the water delivery tunnel in the concrete base; a remote-controlled electric hydraulic pump is provided on the concrete base.

[0009] A remote sensing thermometer is provided at the outer bottom of the outer water intake casing, and the water intake depth is selected by detecting the temperature of the irrigation water.

[0010] The inner wall of the outer water intake sleeve is provided with a sleeve positioning ring for limiting the position of the inner water intake sleeve.

[0011] A trash rack is provided on the top of the inner water intake casing to isolate floating dirt.

[0012] A manhole is provided on the top of the outer water intake casing for inspection and maintenance.

[0013] The utility model has a cap-type surface water intake with remote control. The outer water intake casing is lifted by a floating ball, so that the outer water intake casing moves up and down along the water surface. At the same time, the relative position of the outer water intake casing underwater is adjusted by the piston rod of the hydraulic cylinder, thereby changing the water intake depth; the concrete base plays a role in supporting and fixing the inner water intake casing and the water transmission tunnel.

[0014] The beneficial effects of the present invention are: convenient construction, safe and stable operation, low cost, reduced construction workload compared to traditional methods, lowered requirements of the water inlet building on the underwater foundation, and more flexible and convenient operation.
