[0029] In order to make those skilled in the art better understand the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only a part of the embodiments of the present application, not all. Based on the embodiments recorded in the present application, all other embodiments obtained by those skilled in the art without paying creative work are within the scope of protection of the present application.

[0030] In the description of the embodiments of the present application, it should be understood that the terms "inside", "outside", "odd-number rack", "even-number rack", "rack thickness", "unit", "section", "truncation group", "number of layers", "main equipment number" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application. In addition, the terms "inside" and "outside" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "inside" and "outside" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0031] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or can communicate with each other; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0032] In order to solve the problem of time-consuming and laborious diaphragm valve status inspection, it is necessary to develop a set of automatic detection equipment to determine the switch status of the valve, so that the original multi-person mode can be changed to a single-person easy control mode, and the diaphragm valve status can be conveniently, quickly and reliably measured, thereby improving work efficiency and saving human resources. The inventor of this application found in the research that the main equipment is installed and arranged on site in a standardized and regular manner. The main equipment on site is distributed in two rows and multiple layers, with hundreds of main equipment and thousands of valves on each layer. The main equipment on each layer is on the same horizontal line, and the valves on each layer are also arranged on the same horizontal line. The horizontal and vertical arrangement positions are relatively fixed. Using the principle of laser ranging, a set of measuring devices can be fixed at the end of a single-layer main equipment. It consists of a fixed base, a bracket, a measuring instrument, and a control system. The measuring instrument and the control system are installed on a special bracket. The bracket can be fixed at the end of the main equipment with the help of a magnetic base. By starting the measuring equipment to emit the corresponding laser, the control system calculates the laser emission distance according to the laser return time to determine whether the valves on this layer are all in the open or closed state. When the valve status is inconsistent, the emitted laser will be blocked, and the return time and distance will be shortened. The control system can calculate the abnormal valve position through the corresponding algorithm and feedback the result on the display screen. Using this device, a single person can complete the status inspection of hundreds of equipment valves at a time, with a reliability of 100%, greatly improving work efficiency and saving work time and human resources.

[0033] Based on the above content, in order to clearly and in detail illustrate the above advantages of the present application, the specific implementation methods of the present application will be described below in conjunction with the accompanying drawings.

[0034] See also Figure 1 , which is a structural schematic diagram of a diaphragm valve status detection device for a uranium enrichment plant provided in an embodiment of the present application.

[0035] The embodiment of the present application provides a diaphragm valve state detection device for a uranium enrichment plant, comprising: a positioning base 7 and two laser rangefinders fixed to the positioning base 7;

[0036] The two laser rangefinders correspond to the inner valve plate 1 and the outer valve plate 2 of the diaphragm valve respectively, and are used to emit laser beams to the corresponding valve plates;

[0037] Targets 8 for reflecting the laser beam emitted by the laser rangefinder are fixed on the inner valve plate 1 and the outer valve plate 2; the two laser rangefinders judge the status of the inner valve plate 1 and the outer valve plate 2 according to the reflected laser beam.

[0038] It should be noted that the inner valve plate 1 and the outer valve plate 2 respectively have three states of "same open", "same closed" and "one open and one closed". When the valve state does not match, the laser emitted by the laser rangefinder will be reflected by the target 8. Therefore, two laser rangefinders corresponding to the inner valve plate 1 and the outer valve plate 2 of the diaphragm valve are used to simultaneously detect the distance from the inner valve plate 1 and the outer valve plate 2 to the laser rangefinder, and then the states of the diaphragm valves of multiple devices on the same layer of main equipment can be detected at the same time.

[0039] In specific implementation, the positioning base 7 is used to position the detection position of the entire detection device. The positioning base 7 can be fixed at the end position of the main device.

[0040] In the embodiment of the present application, based on the principle of laser ranging, a detection device is fixed at the end of the main equipment mounting frame, and the state of the diaphragm valve is determined by laser. Using this device, a single person can complete the status inspection of valves of hundreds of devices at a time, which can eliminate the influence of the detection accuracy and installation accuracy of the sensor, greatly improve the ranging accuracy, and the reliability can reach 100%, ensuring more accurate detection results, greatly improving work efficiency, and saving work time and human resources.

[0041] In some possible implementations of the embodiments of the present application, the device may further include: a bracket 3 and a screw 4; two laser rangefinders, including: an outer laser rangefinder 5 and an inner laser rangefinder 6;

[0042] The bracket 3 is vertically fixed on the upper part of the positioning base 7, the screw rod 4 is horizontally arranged, and one end of the screw rod 4 is fixed on the bracket 3; the screw rod 4 is connected to a mounting plate 9; the outer laser rangefinder 5 and the inner laser rangefinder 6 are horizontally mounted on the mounting plate 9.

[0043] In one example, in order to position the two laser rangefinders to accurate positions, the height of the lead screw 4 on the bracket 3 is variable.

[0044] In another example, a limiting slider 13 is disposed at one end of the screw rod 4 , and a plurality of positioning grooves 10 are disposed at different heights of the bracket 3 for fixing the limiting slider 13 .

[0045] As an example, there may be three positioning grooves 10, and the height of each positioning groove 10 corresponds to a diaphragm valve of a different height, for example, three shelves of different heights.

[0046] In some possible implementations of the embodiments of the present application, the device may further include: a handle 11 and a slider 12;

[0047] A slider 12 is slidably fixed on the screw rod 4 , and the handle 11 drives the slider 12 to move; the mounting plate 9 is fixed on the slider 12 .

[0048] It can be understood that the lead screw 4 is connected to the outer laser rangefinder 5 and the inner laser rangefinder 6 and can move synchronously with the lead screw 4, and is mainly used to position the outer laser rangefinder 5 and the inner laser rangefinder 6 to the accurate position so that the laser can be emitted to the corresponding valve plate. The outer laser rangefinder 5 and the inner laser rangefinder 6 are fixedly arranged on the lead screw 4, and the laser beam emitted is horizontally directed to the corresponding valve plate; the target 8 is installed on the inner valve plate 1 and the outer valve plate 2 and is located between the outer laser rangefinder 5, the inner laser rangefinder 6 and the inner valve plate 1 and the outer valve plate 2, and the target 8 can reflect the laser beam emitted by the outer laser rangefinder 5 and the inner laser rangefinder 6; the inner valve plate 1 and the outer valve plate 2 are fixed structures of the object to be measured, which are connected to the main equipment and reflect the switch state of the main equipment. The bracket 3 is vertically connected to the lead screw 4, and the lead screw 4 can move vertically on the bracket 3, driving the outer laser rangefinder 5 and the inner laser rangefinder 6 to move vertically. There are three positioning grooves 10 on the bracket 3, which can make the lead screw 4 have three vertical positions: upper, middle and lower. The positioning base 7 is vertically rigidly connected to the bracket 3 and cannot be moved. It is used to locate the detection position of the diaphragm valve status detection device of the entire main equipment.

[0049] In one example, a magnetic switch is installed on the positioning base 7. After the staff determines the unit, section, and mounting number, the detection device is placed in a fixed position and positioned and fastened by the magnetic switch on the positioning base 7. After the initial position of the detection device is determined, it is necessary to adjust the position of the outer laser rangefinder 5 and the inner laser rangefinder 6. By moving the slide rail on the lead screw 4, the outer laser rangefinder 5 and the inner laser rangefinder 6 can be positioned to the same horizontal direction as the inner valve plate 1 and the outer valve plate 2. This is the key to determining whether the laser rangefinder can detect the distance between the diaphragm valve plate. In specific implementation, the distance from the corresponding valve plate to the laser rangefinder can be measured based on the reflected laser, thereby determining the specific position of the valve plate in the wrong state.

[0050] The embodiment of the present application provides a diaphragm valve status detection device for a uranium enrichment plant, comprising: a positioning base and two laser rangefinders fixed on the positioning base; the two laser rangefinders correspond to the inner valve plate and the outer valve plate of the diaphragm valve, respectively, and are used to emit laser beams to the corresponding valve plates; the inner valve plate and the outer valve plate are both fixed with targets for reflecting the laser beams emitted by the laser rangefinders; the two laser rangefinders judge the status of the inner valve plate and the outer valve plate according to the reflected laser beams. The embodiment of the present application is based on the principle of laser ranging, and a set of detection devices is fixed at the end of the main equipment mounting frame to judge the status of the diaphragm valve by laser. Using this device, a single person can complete the status inspection of valves of hundreds of equipment at a time, which can eliminate the influence of the detection accuracy and installation accuracy of the sensor, greatly improve the ranging accuracy, and the reliability can reach 100%, ensuring that more accurate detection results are obtained, greatly improving work efficiency, and saving work time and human resources.

[0054] Step S102: The state of the valve plate corresponding to the laser rangefinder that receives the reflected laser beam needs to be adjusted.
