Description

Technical Field

[0001] The present invention relates to the field of gate technology, and in particular to an intelligently controlled steel cable gate for a measurement and control integrated gate system. Background Art

[0002] In order to achieve the rational use of water resources in irrigation areas and alleviate the water use problem in irrigation areas, my country has begun to develop water-saving agricultural irrigation water. With the development of information technology, the integrated measurement and control gate system has been rapidly promoted. The system consists of intelligent control gates, automatic flow metering devices and water diversion control systems; among them, the intelligent control gate is the key link to achieve integrated measurement and control.

[0003] At present, there are various types of gates, including cable gates, rack gates, screw gates, flap gates, etc. Usually, gates of different forms and materials need to be selected according to different conditions of use, such as channel width, water head height, water quality, installation foundation, project budget, etc. In terms of materials, the gate body materials include cast iron gates, stainless steel gates, aluminum alloy gates, etc. Cast iron gates are bulky, energy-intensive, and quickly wear out due to water stops; stainless steel gates are expensive and still have deficiencies in standardization, versatility, energy consumption, maintenance, and lifespan. From the perspective of current gate technology, there are generally problems such as insufficient lifespan, unstable water-stopping performance, poor gate versatility, difficult maintenance, high energy consumption, and insufficient solar power supply. Specifically:

[0004] (1) Current technologies often have problems such as weak corrosion resistance of materials, wear of friction pairs, and insufficient fatigue strength, which greatly reduces the service life.

[0005] (2) Poor water-stopping performance. The usual practice is to install the water-stop sealing strip on the side away from the water, and use water pressure to tightly fit the door leaf and the sealing strip to stop the water. However, when the water head height is small, the fit will not be tight, resulting in water leakage and low reliability.

[0006] (3) Gates are usually powered by mains electricity, which consumes a lot of energy. In an environment without mains electricity, gates are opened and closed manually.

[0007] (4) There are many types of gates on the market, including cable gates, rack gates, screw gates, flap gates, etc. It is usually necessary to select gates of different forms and materials according to different usage conditions, such as channel width, water head height, water quality, installation foundation, project budget, etc., which has a long production cycle and high cost.

[0008] (5) Gate leaves are generally made of cast iron or cast aluminum, which have problems such as low dimensional accuracy, bulkiness, high cost, and inability to meet the producibility of any size. There are also problems such as poor precision of welded gates, such as deformation and distortion, and high production costs.

[0046] This specific implementation method has the technical advantages of long service life, high reliability, low energy consumption, strong versatility and low cost through a multi-hanging point steel cable gate body, an intelligent control system and a solar power supply device gate system. The specific technical solution is as follows:

[0047] (1) Long service life: The service life is extended mainly from three aspects: door leaf strength, kinematic pair wear and material corrosion:

[0048] ① Strength: The door leaf adopts a sandwich structure such as aluminum frame, aluminum alloy plates on both sides, honeycomb aluminum or foam aluminum inside. The frame profile is made of 6061 alloy, 6063-T5 or 7075 alloy, and the aluminum alloy cover plate is made of 3003 aluminum alloy or 5052 aluminum alloy plate. The application of composite materials such as honeycomb aluminum and foam aluminum can improve the strength of the door leaf and reduce its weight; the bending strength of the sandwich structure can reach 740kN / m 2 , combined with the strength of the frame and covering plate, the overall bending strength of the door leaf can reach ten to dozens of times that of aluminum plates of the same weight;

[0049] ② Wear resistance: The door leaf is attached with a polymer wear-resistant lining at the position where it contacts the column slide and the water-stop rubber. It has high wear resistance. In a sandstorm environment, its wear resistance is about six times that of carbon steel under the same conditions. The transmission parts are made of high-quality structural steel with chrome plating on the surface, which has high strength and hardness, and is wear-resistant and corrosion-resistant. The entire system has very little wear during operation and is maintenance-free.

[0050] ③Corrosion resistance: The door frame and each door are made of high-strength aluminum alloy, with hard anodizing treatment on the surface, which has strong weather resistance and corrosion resistance; the transmission parts are made of high-quality structural steel with chrome plating on the surface, which is wear-resistant and corrosion-resistant; the water stop is sealed with silicone rubber, which has strong weather resistance and aging resistance of up to thirty years; the slide rail is lined with high wear-resistant lining, which has the characteristics of low friction, high wear resistance and strong weather resistance.

[0051] (2) High reliability: Water-stopping is achieved through two reliable methods:

[0052] ① Dynamic pressure water-stopping method: Install a wedge-shaped pressing device on the water-facing surface of the door leaf. When the water pressure is insufficient, the wedge-shaped pressing device can still tightly fit the door leaf and the water-stopping strip;

[0053] ② Static pressure water-stop method: install the water-stop sealing strip on the water-facing surface of the gate, and pre-tighten the water-stop strip during installation so that it can fit tightly with the door leaf regardless of water pressure to achieve the purpose of water-stopping. This method is based on installing a lining plate made of low-friction material on the door leaf frame. The lining plate can be made of polytetrafluoroethylene or high-density polyethylene.

[0054] (3) Low energy consumption: The gate is powered by solar energy in an environment without mains electricity. Electric energy is generated by monocrystalline or polycrystalline solar panels and then stored in batteries for gate opening and closing and information collection. Since the amount of solar power is greatly affected by the weather, the device solves the energy consumption problem by improving transmission efficiency, reducing friction resistance, and lightweight door leaf design. The details are as follows:

[0055] ① Transmission efficiency: The cable winch is used to open and close the gate instead of the traditional screw gate, rack gate, etc. The rolling friction transmission efficiency is much higher than the sliding friction transmission efficiency, and the efficiency is generally higher than 75%;

[0056] ② Wear resistance: The door leaf is attached with a polymer wear-resistant lining at the position of contact with the column slide and water-stop rubber. The lining is made of polytetrafluoroethylene and high-density polyethylene. The friction coefficient with aluminum is as low as 0.1 or less, and the friction coefficient with rubber is as low as 0.3 or less, which can reduce friction resistance;

[0057] ③ Lightweight door leaves: Through the application of composite materials such as honeycomb aluminum and foam aluminum, the strength of door leaves can be met and the weight of door leaves can be reduced. The overall bending strength of door leaves can reach ten to dozens of times that of aluminum plates of the same weight.

[0058] (4) Strong versatility: The multi-hanging point winch gate is adopted to achieve the requirements of universalization, serialization and combination. The multi-hanging point opening and closing method can adopt different numbers of hanging points for gates of different sizes. For example, small gates adopt double hanging points for opening and closing, large gates adopt four hanging points for opening and closing, or even more hanging points for opening and closing. At the same time, during the design and production process, the opening and closing part can be made into a standardized module. According to the size requirements of the channel gate, the combination requirements of the product can be achieved through the multi-hanging point module, thereby improving versatility.

[0059] (5) Low cost: The product adopts standardized module design and uses molding processes such as extrusion profiles and casting to greatly reduce costs.
