Description

Technical Field

[0001] This invention belongs to the field of water conservancy engineering technology, and specifically relates to a valve device for water conservancy pipelines. Background Technology

[0002] In the field of water conservancy engineering, pipeline valves are key equipment for achieving water flow control, and their performance directly affects the stable operation of the water conservancy system and the rational allocation of water resources. Currently, there is a wide variety of types of water conservancy pipeline valves, including gate valves, butterfly valves, ball valves, and many others. However, these traditional valves generally face a series of problems that urgently need to be solved in practical applications.

[0003] In terms of operational difficulty, most traditional valves have complex structures. Whether operated manually or controlled with the aid of ordinary drive devices, they require operators to possess high levels of professional skills and extensive experience. For example, the opening and closing of some large gate valves often requires the coordinated operation of multiple people, and the control of parameters such as force and angle during operation is extremely precise. The slightest carelessness may lead to the valve not opening or closing properly, thereby affecting the normal operation of the entire water conservancy system.

[0004] Regarding malfunctions, traditional valves suffer from a persistently high failure rate. On the one hand, due to prolonged exposure to complex operating conditions such as water flow erosion and pressure changes, vulnerable parts of the valves, such as sealing components and transmission mechanisms, are prone to wear and aging, leading to malfunctions such as leakage and jamming. On the other hand, the design of some valves lacks sufficient consideration for extreme operating conditions. When dealing with special hydrological conditions such as floods and droughts, they are prone to structural damage due to excessive load, seriously affecting the safety and reliability of water conservancy projects.

[0005] In view of this, the present invention is proposed to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a new type of water conservancy pipeline valve that is easy to operate, has stable performance, and is convenient to maintain, so as to meet the needs of modern water conservancy projects for efficient and reliable water flow control equipment.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A water conservancy pipeline valve device further includes a lifting device installed on the upper side of a dam or river embankment, the bottom of the lifting device is connected to a cable, an electromagnet is fixed to the bottom of the cable, and both the electromagnet and the lifting device are electrically connected to an external power source. A valve body is installed below the lifting device. The valve body is a double-conical structure with the same bottom and hollow inside. The valve body is installed corresponding to the water inlet of the dam.

[0008] Furthermore, the lifting device includes a support frame and a drive motor. A pulley block is provided at the bottom of the support frame, and the drive motor is connected to the pulley block via a steel wire rope.

[0009] Furthermore, the valve body is made of aluminum alloy shell and filled with sand and gravel. An iron plate is welded and fixed to the top of the valve body for connecting an electromagnet.

[0010] Furthermore, the lifting device is an aircraft, and an emergency valve body is connected to the bottom of the aircraft. The emergency valve body is a trapezoidal hopper used to block the breach.

[0011] The beneficial effects of this invention are as follows: Ease of operation: The new type of hydraulic electromagnetic crane consists of a motor, electromagnet, and pulley block. With the help of a remote motor and camera, it can easily open and close the gate without the need for complicated close-range manual operation. This reduces the difficulty and safety risks of manual operation.

[0012] Structural performance advantages: The conical valve design results in less buoyancy during descent and less resistance during ascent. Compared with traditional valves, the opening and closing process is smoother and more efficient, reducing energy consumption during valve opening and closing, and lowering the probability of valve failure due to resistance and buoyancy issues.

[0013] Convenience of maintenance: The valve structure is relatively simple. In case of failure, disconnecting the power supply will demagnetize the electromagnet, allowing the electromagnet and lifting assembly to be brought ashore for maintenance. This eliminates the need for large-scale disassembly of the complex underwater valve body, simplifying the maintenance process and saving maintenance time and costs.

In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, the preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0017] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0019] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0020] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] Please see Figure 1 The water conservancy pipeline valve device shown in a preferred embodiment of this application includes a bracket 2 and a drive motor 3 installed on the upper side of the water inlet 8 of the water pipe of the dam 1. A pulley block 4 is provided at the bottom of the bracket 2. The drive motor 3 is connected to the pulley block 4 through a steel wire rope. A cable 5 is connected to the bottom of the pulley block 4. An electromagnet 6 is fixed at the bottom of the cable 5.

[0022] Specifically, both the electromagnet 6 and the drive motor 3 are electrically connected to an external power source.

[0023] A valve body 7 is installed above the water inlet 8. The valve body 7 is a double cone structure with the same bottom at the top and bottom, and is hollow inside. Preferably, the valve body 7 is made of aluminum alloy shell and filled with sand and gravel. An iron plate is welded and fixed to the top of the valve body 7 for connecting the electromagnet 6.

[0024] Preferably, surveillance cameras are also installed on the dam to monitor the operation process in real time.

[0025] Preferably, the surface of the electromagnet is covered with a waterproof insulating layer to improve safety and extend its service life.

[0026] Working principle: The drive motor 3 and electromagnet 6 are operated remotely via wireless remote control. After the electromagnet 6 attracts the valve body 7, the drive motor 3 raises and lowers the valve body 7 to open and close the water inlet 8, thereby opening and closing the valve of the water conservancy project pipeline. It is convenient, fast and trouble-free. After disconnecting the power supply to the electromagnet 6, all components can be recovered.

[0027] Furthermore, as an emergency measure for breaches in the river embankment 12, the emergency valve body 14 can be transferred using a lifting device to block the breach. In this embodiment, an aircraft 13 is used for the transfer. The emergency valve body 14 is a trapezoidal hopper that is lifted by a drone, which is convenient, simple, efficient, and will not be washed away by the flood, thus playing a blocking role. After the operation is completed, it can be reinforced with reinforced concrete. Flood control and rescue operations and marine rescue activities require every second to act, and the use of drones should be vigorously promoted. This can reduce property damage and casualties. Because these are high-risk operations, the use of drones is very efficient.

[0028] Furthermore, the lifting operation by drone requires a large amount of energy, which can be supplied by a supercritical carbon dioxide power generation system. The applicant has already disclosed this technology in the patent application number 2025104294252, so it will not be elaborated here.

[0029] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
