Description

Technical Field

[0001] The present invention relates to the technical field of gate valves, and in particular to a remote-controlled gate valve opening device based on photoelectric compensation and a use method thereof. Background Art

[0002] In the current gate valve application field, traditional electric gate valves occupy a certain market share. However, there are many problems that cannot be ignored in the actual use of traditional electric gate valves, among which the on-site wiring problem is particularly prominent.

[0003] The operation of traditional electric gate valves relies on electric drive, which requires on-site wiring during installation and use. First of all, on-site wiring is a tedious and complicated task. In many practical scenarios, such as complex pipeline layout areas in large factories and urban underground pipe network systems, laying wires for electric gate valves requires facing various complex environments and space restrictions. Construction personnel not only need to carefully plan the line path to avoid conflicts with other pipelines and equipment, but also need to perform a large number of wall and pipe penetration operations, which undoubtedly increases the difficulty and workload of construction.

[0004] Secondly, the cost of on-site wiring is high. In addition to purchasing a large amount of wires and cables and other materials, manpower is also required for laying and installation. In some special environments, such as places with strong corrosiveness, special wires need to be selected, which further increases the cost. Moreover, once a line fails, troubleshooting and repair work is also very troublesome, requiring a lot of time and manpower costs.

[0005] Furthermore, the flexibility of on-site wiring is poor. Once the installation position of the gate valve needs to be adjusted or the pipeline system needs to be modified, the original wiring may not be able to meet the new requirements and needs to be re-wired, which brings great inconvenience to practical applications.

[0006] In addition, in some remote areas or temporary installations, on-site wiring may face insufficient or unstable power supply, which will seriously affect the normal operation of traditional electric gate valves. For example, in some outdoor water conservancy projects, in order to power the electric gate valve, it may be necessary to lay a long transmission line, which is not only costly but also difficult to maintain. Once a power failure occurs, the gate valve will not work properly, which may have a serious impact on the operation of the entire water conservancy system.

[0007] In summary, the on-site wiring problems of traditional electric gate valves have brought many challenges to their installation, use, maintenance and cost control. There is an urgent need for a remote control gate valve opening device based on photoelectric compensation and a method of use to improve the convenience, reliability and economy of gate valve control.

[0045] See also Figures 1 to 9. It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings in this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the effects and purposes that can be achieved by the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0046] The present invention provides a technical solution: a remote-controlled gate valve opening device based on photoelectric compensation, comprising a valve body 1, the middle part of the valve body 1 is arranged in a circular ring shape, and a circular metal valve plate 2 is movably sleeved on the inner wall.

[0047] The circular metal valve plate 2 is used to control the on and off of the water flow by rotating. The metal connecting shaft 3 fixedly connected at the bottom rotates vertically downward through the bottom of the valve body 1, and the metal column 4 fixedly connected at the top rotates vertically upward through the top of the valve body 1. The top of the metal column 4 is fixedly connected to a metal sphere 5.

[0048] The circular metal valve plate 2, the metal connecting shaft 3, the metal column 4 and the metal sphere 5 are made of copper. Copper has good thermal conductivity and electrical conductivity, which is beneficial to heat transfer and the formation of temperature difference potential.

[0049] A plurality of transversely arranged heat sinks 9 are fixedly connected to both sides of the circular metal valve plate 2 to enhance heat dissipation. When sunlight is focused to heat the metal sphere 5 and other components, the water flow can quickly take away the heat when passing through.

[0050] The focusing assembly 6 includes a spherical shell 601 slidably sleeved on the outer wall of the metal sphere 5 , a focusing tube 602 is fixedly connected to the top opening of the spherical shell 601 , and a convex lens 603 is fixedly sleeved on the inner wall of the top port of the focusing tube 602 .

[0051] The convex lens 603 can focus sunlight onto the metal sphere 5 to generate heat, thereby improving energy utilization efficiency.

[0052] The adjustment mechanism 8 includes a rotating ring 801 rotatably sleeved on the outer wall of the heat-insulating sleeve 7, a second motor 802 is fixedly mounted on the outer wall of the rotating ring 801, a strip plate 803 is fixedly mounted on the side wall of the second motor 802, a third motor 804 is fixedly mounted on the side wall of the strip plate 803, the end of the output shaft of the third motor 804 is fixedly connected to the outer wall of the metal sphere 5, and the axis of the output shaft coincides with the center of the metal sphere 5. The output end of the second motor 802 is axially connected to a gear 805, and the gear 805 is meshed with a gear ring 806 fixedly sleeved on the outer wall of the heat-insulating sleeve 7. The top port of the rotating ring 801 is fixedly connected to a heat-insulating corrugated telescopic cover 807, and the top port of the heat-insulating corrugated telescopic cover 807 is fixedly connected to the bottom port of the spherical shell 601.

[0053] The second motor 802 can drive the rotating ring 801 and the entire focusing assembly 6 to rotate around the heat-insulating sleeve 7 through the cooperation of the gear 805 and the gear ring 806 to achieve horizontal angle adjustment. The third motor 804 can directly adjust the vertical angle of the metal sphere 5 and the focusing assembly 6, so that the light inlet of the focusing assembly 6 can be accurately aligned with the sun, improving the sunlight focusing effect. The heat-insulating corrugated telescopic cover 807 plays the role of heat insulation and protection of the connection parts, preventing heat from being transferred to other components and affecting their normal operation.

[0054] The top of the valve body 1 is fixedly connected with a heat insulating sleeve 7 which is rotatably sleeved on the outer wall of the metal column 4. The heat insulating sleeve 7 plays a heat insulating role, reducing the heat transfer from the metal sphere 5 to other parts of the valve body 1, thereby improving energy utilization efficiency and device stability.

[0055] A rectangular plate 11 with an adjustable horizontal position is also mounted on the heat-insulating sleeve 7. A plurality of light intensity sensors 12 are fixedly laid in a matrix on the top surface of the rectangular plate 11 for detecting the intensity and direction of sunlight.

[0056] The top surface of the rectangular plate 11 is also fixedly connected with a column 13, a compass 20 is inlaid on the top of the column 13, and a mark 21 is set on the top of the column 13. The column 13 is set at the center position of the rectangular plate 11 and close to the edge of one side of the focusing assembly 6. The rectangular plate 11 is higher than the top of the focusing assembly 6. When the compass 20 points to the mark 21, the position of the rectangular plate 11 can be determined.

[0057] A controller 14 and a storage battery 15 are installed below the rectangular plate 11, and the controller 14 is electrically connected to the storage battery 15. The positive electrode of the storage battery 15 is electrically connected to an electric slip ring 16 through a wire, the inner ring of the electric slip ring 16 is fixedly sleeved on the outer wall of the metal connecting shaft 3, and the outer ring is fixedly connected to the valve body 1. The negative electrode of the storage battery 15 is electrically connected to the metal sphere 5 through a wire, and a number of light intensity sensors 12 are electrically connected to the controller 14. When the metal sphere 5 is heated and forms a temperature difference potential with the metal connecting shaft 3, the storage battery 15 can be charged to achieve photoelectric compensation. The storage battery 15 is used to provide power for the operation of each unit of the control gate valve.

[0058] The outer wall of the heat insulating sleeve 7 is rotatably sleeved with a support plate 17, and the side wall of the support plate 17 is threadedly penetrated with a clamping bolt 18, and the end of the clamping bolt 18 is pressed against the outer wall of the heat insulating sleeve 7. By loosening and tightening the clamping bolt 18, the angle and position of the support plate 17 on the heat insulating sleeve 7 can be adjusted.

[0059] The top surface of the support plate 17 is fixedly connected with a cylindrical tube 19, and the top of the cylindrical tube 19 is fixedly connected to the bottom of the rectangular plate 11. Such a structural design not only ensures the installation stability of the rectangular plate 11, but also can adjust the horizontal position of the rectangular plate 11 by adjusting the support plate 17, so that it can be accurately located on the north side of the focusing assembly 6, so as to better detect the sunlight information.

[0060] The controller 14 and the storage battery 15 are fixedly installed inside the cylindrical barrel 19. The cylindrical barrel 19 provides a relatively closed and stable installation environment for the controller 14 and the storage battery 15, which is conducive to protecting these components from the influence of the external environment, and is also convenient for wiring and connecting other components. The controller 14 and the storage battery 15 are integrated and installed in the cylindrical barrel 19, which can also make the structure of the device more compact, reduce the occupied space, and improve the overall aesthetics and practicality.

[0061] The remote control gate valve opening device based on photoelectric compensation also includes a wireless transmission module connected to the controller for background remote control.

[0062] A method for using a remote control gate valve opening device based on photoelectric compensation comprises the following steps:

[0063] Step 1: Install the two ports of the valve body 1 on the outdoor water supply pipe, adjust the position of the rectangular plate 11, and make the rectangular plate 11 be located on the north side relative to the focusing assembly 6, and open the control gate valve to allow water to flow through;

[0064] Step 2: The sun shines on the pillars 13, and the pillars 13 form shadows on the light intensity sensors 12. An XY coordinate system is established on the light intensity sensors 12 laid out in a matrix, and the position of the axis of the pillars 13 is set as the origin of the coordinate system. The height of the pillars 13 is h, the solar altitude angle is α, and the azimuth angle of the sun is β. Then the coordinate set of the light intensity sensor 12 is {(x1, y1), (x2, y2), (x3, y3), ..., (x n ,y n )}, the coordinates of the end of the shadow of column 13 are (x i ,y i );

[0065] The controller gets ;

[0066] when , When ;

[0067] when , When ;

[0068] Since the light intensity of the shadow part is weak, the light intensity sensor covered by the shadow can be determined;

[0069] Step 3: The controller adjusts the angle of the focusing assembly 6 through the adjustment mechanism 8 according to the calculated α and β values, so that the light inlet of the focusing assembly 6 is aligned with the sun. The specific operation is as follows:

[0070] The controller sends out a command to control the second motor 802 to start, and through the transmission of the gear 805 and the gear ring 806, drives the rotating ring 801 and the entire focusing assembly 6 to rotate around the heat insulation sleeve 7 to adjust the angle in the horizontal direction.

[0071] At the same time, the controller controls the third motor 804 to start, directly adjusting the vertical angles of the metal sphere 5 and the focusing assembly 6. Through the coordinated work of the two motors, it is ensured that the focusing assembly 6 can accurately focus the sunlight on the metal sphere 5, thereby improving the energy collection efficiency;

[0072] Step 4: The focusing component 6 focuses sunlight on the metal sphere 5 to generate heat. When the water flows through the circular metal valve plate 2 and the heat sink 9, the heat can be quickly taken away. Since there is a temperature difference between the heated metal sphere 5 and the metal connecting shaft 3, a temperature difference potential is formed between the metal sphere 5 and the metal connecting shaft 3 according to the Seebeck effect.

[0073] At this time, the positive electrode of the storage battery 15 is connected to the metal connecting shaft 3 through the electric slip ring 16, and the negative electrode is connected to the metal sphere 5, forming a closed loop. The temperature difference potential charges the storage battery 15, realizing photoelectric compensation, and converting solar energy into electrical energy for storage;

[0074] Step five, the electric energy stored in the storage battery 15 is used to provide electric energy for the operation of each unit of the control gate valve, including the operation of the controller 14, the first motor 10, the second motor 802, the third motor 804 and other components, to realize the self-power supply and remote control functions of the device, and improve the energy utilization efficiency and operation reliability of the device.

[0075] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
