Description

Technical Field

[0001] The present invention belongs to the technical field of pumped - storage valve monitoring, and particularly relates to a freely movable vertical pipe valve anti - rotation monitoring and warning tool. Background Art

[0002] In the pumped - storage underground power house, the pipeline laying is becoming increasingly complex, there are many valves on the pipelines, and the units often start and stop frequently. Therefore, the units are in a non - steady - state transition process for a long time. During the transition process, the vibration of the units is large, which also causes the problem of valve loosening, thus affecting the normal operation of the pipeline.

[0003] Due to the large number of pipelines and the large number of valves installed on each pipeline, the problem of valve loosening is often difficult to supervise, and the problem of valve reverse rotation is likely to occur, leading to accidents. There is a need for a tool that can move flexibly to monitor any important valve in real - time. Summary of the Invention

[0004] Aiming at the problems in the current pumped - storage field, such as a large number of pipelines and valves, difficult to supervise, and prone to valve reverse rotation problems leading to accidents, the present invention provides a freely movable vertical pipe valve anti - rotation monitoring and warning tool, which can be moved and placed around the valve at any time and fixed, and can contact the amplitude rod of the valve at the best swing rod angle to form a combination for detecting the rotation of the valve.

[0005] The solution adopted by the present invention to solve its technical problems is: a freely movable vertical pipe valve anti - rotation monitoring and warning tool, including a base, a swing mechanism, a grating body, a laser emitter and a laser receiver.

Further, a locking wire is installed outside the composite outer tube, and through the locking wire, the composite outer tube and the core rod can be locked. In the locked state, the two cannot move axially.

[0008] A swing rod is vertically fixed to the upper end of the core rod, a needle base is fixed to the end of the swing rod, and a positioning needle is vertically installed below the needle base.

[0009] The grating body is a sector body, its upper surface and lower surface are respectively fan-shaped, and a series of through slots are evenly distributed at equal angles between the upper and lower surfaces.

[0010] The laser emitter and the laser receiver are respectively connected to signal lines, and each signal line is respectively connected to the signal sending end and the signal receiving end of the controller. The controller controls the buzzer to emit an alarm signal according to the trigger signal of the laser receiver.

[0011] The core rod is fixedly connected to the grating body through a connecting rod. There is a hanging hole in the middle of the connecting rod, and tension springs are respectively connected to both sides of the hanging hole, forming a balanced and repulsive relationship.

[0012] A hoop is fixed below the base and is fixed to the pipe body through the hoop. An extreme stop is fixed in the accommodation chamber.

Through the magnet 15, the tool can be attracted to any suitable position close to the valve.

[0023] An enclosed accommodation chamber 2 is provided on the upper part of the base 1. A fixed sleeve 3 is provided at the center of the accommodation chamber 2. A composite outer tube 4 is fitted inside the fixed sleeve 3. A limiting retaining platform is provided between the fixed sleeve 3 and the composite outer tube 4, so that the two can only rotate and cannot move axially.

[0024] A core rod 5 is fitted inside the composite outer tube 4. The sides of the composite outer tube 4 and the core rod 5 are provided with convex - concave inlaid structures or milled flat surfaces along the axial direction, so that the two can only expand and contract axially and cannot rotate. Further, a locking wire 6 is installed outside the composite outer tube 4. Through the locking wire 6, the composite outer tube 4 and the core rod 5 can be locked, and they cannot move axially in the locked state.

[0025] A swing rod 7 is vertically fixed at the upper end of the core rod 5. A needle seat 8 is fixed at the end of the swing rod 7. A positioning needle 9 is vertically installed below the needle seat 8. When in use, the positioning needle 9 is closely attached to one side of the valve's spoke in the rotation direction. When the invention rotates in the reverse direction, the positioning needle 9 is first driven to move.

[0026] A grating body 10 is installed at the lower end of the composite outer tube 4. Specifically, a sector - shaped grating body 10 as shown in the figure is installed inside the accommodation chamber 2. As can be seen from the figure, the grating body 10 is a sector body, its upper surface and lower surface are both sectors, and a series of through - slots are evenly distributed at equal angles between the upper and lower surfaces. Figure 2 As shown in the figure, a sector - shaped grating body 10 is installed at the lower end of the composite outer tube 4. Specifically, a sector - shaped grating body 10 as shown in the figure is installed inside the accommodation chamber 2. As can be seen from the figure, the grating body 10 is a sector body, its upper surface and lower surface are both sectors, and a series of through - slots are evenly distributed at equal angles between the upper and lower surfaces.

[0027] As shown in the figure, Figure 3 there is a laser emitter 11 above the grating body 10 and a laser receiver 12 below it, and the laser emitter 11 and the laser receiver 12 are respectively located at the corresponding upper and lower positions of the grating body 10. From Figure 1It can be seen that the laser emitter 11 is fixed at the perforated position above the accommodation chamber, and the laser receiver 12 is fixed at the bottom of the accommodation chamber 2. The laser emitter 11 and the laser receiver 12 are respectively connected to signal lines, and each signal line is respectively connected to the signal sending end and the signal receiving end of the controller. The controller controls the buzzer to emit an alarm signal according to the trigger signal of the laser receiver 12.

[0028] When the above embodiment is in use, the tool is moved and adsorbed at a suitable position near the valve (since the position of the valve rod is uncertain, after moving the tool to a suitable position, it is beneficial to the swinging positions of the swing rod 7 and the positioning pin 9). Then, the core rod 5 is rotated to a suitable angle, and then the locking wire 6 is loosened, and the core rod 5 is pulled outwards, so that the swing rod 7 and the positioning pin 9 are pulled outwards. After crossing the valve bracelet, it is tightened inward to make the positioning pin 9 fit the auxiliary rod of the valve, and the locking wire is tightened to be in the monitoring state.

[0029] Embodiment 2: On the basis of Embodiment 1, as Figure 2 shown, the core rod 5 is fixedly connected to the grating body 10 through a connecting rod 13. There is a hanging hole in the middle of the connecting rod 13, and tension springs 14 are respectively connected to both sides of the hanging hole, forming a balanced repulsive relationship.

[0030] Embodiment 3: A hoop is fixed below the base 1 and is fixed to the pipe body through the hoop. An extreme stop is fixed in the accommodation chamber 2. When the connecting rod 13 swings a certain angle and contacts the extreme stop, it stops rotating, so that the swing rod 7 and the positioning pin 9 can form a locking relationship with the valve rod.
