[0004] Although the equipment can monitor the faults of electric valves, it cannot determine whether the electric valve can open or close normally after maintenance. It still requires manual visual inspection of whether the gate is open or closed, which makes the observation extremely inconvenient. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problem mentioned in the background art that although the device can monitor the faults of electric valves, it is impossible to determine whether the electric valve can open or close normally after maintenance, and manual visual observation is still required to check whether the gate is open or closed, which makes observation extremely inconvenient, the present invention adopts the following technical solution.

[0007] An electric valve fault detection device includes a mounting plate, a fault detection device is provided on one side of the mounting plate, and support horizontal plates are fixedly connected to both sides of the mounting plate near the bottom. A detection component is installed on one side of the support horizontal plate, and the detection component detects whether the electric valve can open and close normally.

[0008] Preferably, a width adjustment component is installed on the mounting plate, and a semi-circular locking block is installed on the width adjustment component. The width adjustment component can make the two semi-circular locking blocks move towards each other or in opposite directions at the same time.

[0009] Preferably, a height adjustment component is installed on the mounting plate, which allows the semi-circular block to move upward and downward.

[0010] Preferably, the detection assembly includes a detection rod, a pull handle, a return spring, a detection plate, a sliding rod, a first collar, a second collar, and a fastening bolt. A sliding rod is fixedly connected to the upper end of a side support plate. A first collar is sleeved on the outer wall of the sliding rod. A detection rod is provided on one side of the first collar. A second collar is sleeved on the outer wall of the detection rod. A fixing rod is fixedly connected between the second collar and the first collar. Fastening bolts are threadedly connected to the first and second collars. The threaded end of the fastening bolt is inserted into the outer wall of the contact detection rod or the sliding rod. A detection plate is detachably connected to one end of the detection rod. A return spring is sleeved on the outer wall of the detection rod between the detection plate and the second collar. A pull handle is fixedly connected to the other end of the detection rod.

[0011] Preferably, the height adjustment assembly includes a sliding groove, a drive screw, a first drive motor, a sliding block, and a sliding rail. Sliding grooves are provided on both sides of the mounting vertical plate. Drive screws are rotatably connected inside the sliding grooves on both sides. The lower ends of the drive screws on both sides pass through the mounting vertical plate and are fixedly connected to sprockets. Linkage chains are sleeved on the outer walls of the sprockets on both sides. The upper end of the mounting vertical plate is detachably connected to the first drive motor. The rotating end of the first drive motor is detachably connected to the upper end of one drive screw. Sliding rails are installed on the outer walls of the two semi-circular blocks on both sides. Sliding blocks are fixedly connected to the upper ends of the sliding rails. The sliding blocks are slidably connected to the inside of the sliding grooves and threadedly connected to the outer walls of the drive screws.

[0012] Preferably, the lateral movement component includes a bidirectional screw and a second drive motor. The bidirectional screw is rotatably connected inside the sliding rail.

With the set detection components, the detection plate is inserted into the inside of the electric valve to contact the gate. The height of the detection plate can be adjusted by loosening the fastening bolts on the first ring. When the gate of the electric valve is normally open, it will push the detection plate and detection rod to move laterally and compress the return spring. When the electric valve is normally closed, the return spring will reset the detection rod and detection plate. This allows for a direct observation of whether the electric valve can open and close normally, making the detection more convenient. When installing the electric valve, hold the pull handle and pull it outward and tighten the fastening bolts to fix it, so as not to obstruct the electric valve from being placed on the semi-circular block.

[0014] 2. With the height adjustment component, the first drive motor rotates, driving the drive screw on one side to rotate. The sprocket and linkage chain enable the drive screw on the other side to rotate simultaneously, thereby moving the semi-circular block upward and raising the electric valve, making fault detection and maintenance more convenient.

[0015] 3. Through the width adjustment component, the second drive motor rotates and drives the bidirectional screw to rotate, so that the two semi-circular blocks on both sides can move in opposite directions at the same time, thereby adjusting according to the size of the electric valve so that electric valves of different sizes can be placed.

The present invention provides the following embodiments.

[0021] like Figure 1 The diagram shows a preferred embodiment of an electric valve fault detection device of this utility model. This embodiment includes a mounting plate 100, with a fault detection device (not shown in the diagram, as described in the background art reference document) on one side of the mounting plate 100. Supporting horizontal plates 101 are fixedly connected to both sides of the mounting plate 100 near the bottom. Semi-circular locking blocks 300 are provided on both sides of the mounting plate 100, with grooves on their inner walls. The flanges on both sides of the electric valve are locked inside the grooves of the semi-circular locking blocks 300. A detection rod 200 is provided on one side of the electric valve and inserted into the valve. In this embodiment, after the electric valve is repaired, opening and closing tests are performed. When the gate rotates, the detection rod 200 moves laterally outward. By observing whether the detection rod 200 moves laterally, it is possible to determine whether the electric valve can open and close normally, thus directly determining whether the electric valve is functioning correctly.

[0022] like Figure 2As shown, this is a schematic diagram of the detection component structure in this embodiment. A sliding rod 204 is fixedly connected to the upper end of a supporting horizontal plate 101 on one side. A first collar 205 is sleeved on the outer wall of the sliding rod 204.
