[0025] Embodiment 1

[0026] like Figures 1 to 3As shown, the utility model proposes a device for measuring the opening of a screw-type gate, including a gate body 1, the gate body 1 includes a gate frame 11, the gate body 1 also includes a drive motor 12, and the drive motor 12 is installed at the center of the top outer surface of the gate frame 11, and the output end inside the drive motor 12 is threadedly connected with a threaded rod 13, and the outer surface of the bottom end of the threaded rod 13 is fixedly connected with a gate plate 14, and the drive motor 12 is set as a screw motor. The screw motor is a common linear motor, which is mainly used in occasions where precise control of linear position and speed is required. The linear motion is achieved by the rotation of the motor. A high-precision ball screw or roller screw is usually used. The operation of the drive motor 12 can be controlled by the control panel 27, thereby driving the threaded rod 13 to move up and down to adjust the opening of the gate plate 14;

[0027] The mechanical measuring mechanism 2 includes a hook 21, and the outer surface of one end of the hook 21 is fixedly connected to the outer surface of one end of the inner top of the gate frame 11. The hook 21 can hang the hanging ring 26. When the gate plate 14 moves, it will drive the winding wheel 23 to rotate, so that the cable 25 extends, and the motion sensor 24 monitors the rotation position of the winding wheel 23;

[0028] The mechanical measuring mechanism 2 also includes a fixing frame 22, and the outer surface of the bottom of the fixing frame 22 is fixedly connected to one end of the outer surface of the top of the gate plate 14, and the inner bearing of the outer surface of the upper end of the fixing frame 22 is connected to a winding wheel 23, and the outer surface of one end of the winding wheel 23 is fixedly connected to a spring, and a motion sensor 24 is installed on the outer surface of one end of the fixing frame 22, and the inner part of the other end of the fixing frame 22 is provided with a spring, which can drive the winding wheel 23 to rotate and automatically retract the cable 25, and the motion sensor 24 can record the number of revolutions of the winding wheel 23, so as to monitor the height data of the gate plate 14;

[0029] A cable 25 is fixedly connected to the center of the outer surface of the winding wheel 23, and a hanging ring 26 is fixedly connected to the outer surface of one end of the cable 25, and the hanging ring 26 is sleeved on the outer surface of the hook 21. A control panel 27 is installed on the outer surface of the other end of the top of the gate frame 11. The control panel 27 can control the operation of the drive motor 12, and is electrically connected to the motion sensor 24 and the position sensor 31, so that the motion sensor 24 and the position sensor 31 can transmit the monitored data to the control panel 27. When the gate plate 14 rises, the fixed frame 22 moves up, and the winding wheel 23 rotates to reel in the cable 25 under the drive of the elasticity of the spring itself. The motion sensor 24 records the rotation state of the winding wheel 23 to determine the length of the cable 25 that is reeled in, that is, the height to which the gate plate 14 rises. When the gate plate 14 descends, the fixed frame 22 moves down, and the rotation of the winding wheel 23 will stretch the spring, and the motion sensor 24 continues to record the rotation state of the winding wheel 23.

[0030] Embodiment 2

[0031] like Figure 4 and Figure 5 As shown, this embodiment also proposes:

[0032] The intelligent measuring mechanism 3 includes a position sensor 31, and the position sensor 31 is installed on the outer surface of one end of the top of the gate frame 11. The position sensor 31 is set as a photoelectric linear displacement sensor. The photoelectric linear displacement sensor is a sensor that detects linear displacement using the principle of photoelectric conversion. It is composed of a light source, a grating, and a photoelectric conversion element. The displacement of the grating changes the light intensity received by the photoelectric conversion element, thereby detecting the displacement. The photoelectric linear displacement sensor has the advantages of high resolution, good linearity, strong anti-interference, etc., and is widely used in industrial automation, mechanical measurement and other fields;

[0033] The intelligent measuring mechanism 3 also includes a sensing track 32, and the outer surface of the upper end of the sensing track 32 is fixedly connected to the inner portion of the outer surface of the lower end of the position sensor 31, and the outer surface of one side of the sensing track 32 is fixedly connected to the outer surface of the other end of the inner side of the gate frame 11. The sensing track 32 passes through the inner portion of the top of the gate frame 11, and the position sensor 31 can detect the position of the sliding block 33 on the outer surface of the sensing track 32, thereby monitoring the height data of the gate plate 14;

[0034] A sliding block 33 is installed at the other end of the top outer surface of the gate 14, and the outer surface of one side of the sliding block 33 is in contact with the outer surface of the other side of the sensing track 32. When the gate 14 moves up and down, it can drive the sliding block 33 to move on the outer surface of the sensing track 32. Therefore, the position sensor 31 measures the opening of the gate 14 by monitoring the position of the sliding block 33.

[0035] Working principle: First, the hanging ring 26 is sleeved on the outer surface of the hook 21. When the driving motor 12 is controlled to work through the control panel 27, the driving motor 12 drives the threaded rod 13 and the gate 14 to rise or fall. When the gate 14 moves inside the gate frame 11, the winding wheel 23 rotates inside the fixed frame 22, pulling the internal spring to rotate. The motion sensor 24 records the number of revolutions of the winding wheel 23, thereby measuring the extended length of the cable 25, and then obtaining the height position data of the gate 14, and transmitting the data to the control panel 27;

[0036] At the same time, when the gate 14 moves, it drives the sliding block 33 to move, so that the position where the sliding block 33 and the sensing track 32 are in contact changes. The position sensor 31 monitors the position of the sliding block 33, thereby transmitting the height data of the gate 14 to the control panel 27. The control panel 27 simultaneously displays the data monitored by the mechanical measuring mechanism 2 and the intelligent measuring mechanism 3. The above is the entire working principle of the utility model.

[0037] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection. "upper", "lower", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may change;
