[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc.; valves are control components in fluid conveying systems, with functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves used in fluid control systems, from the simplest shut-off valves to various valves used in extremely complex automatic control systems, have a wide variety of varieties and specifications.

[0003] According to a disclosed automatic anti-leakage detection and protection device for water conservancy valves (publication number: CN216430684U), when the detector and the controller in the above application are working normally, the battery supplies power to the electric motor, so that the electric motor drives the rotating shaft and the fan blades to rotate, so that the fan blades blow the air entering the strong chamber of the base body from the air inlet to the heat dissipation holes, so that the heat generated by the detector and the controller is dissipated from the heat dissipation holes with the flow of air, thereby avoiding heat aging of the detector and the controller after long-term operation and improving the service life of the device. However, when the device enters the interior from the air inlet through the fan blades, dust will gradually adhere to the filter screen provided on the air inlet, which will affect the internal heat dissipation over time; in view of this, we need a valve leakage detection device.

[0023] In this embodiment, a dust removal mechanism 9 is provided inside the body 1. The cam 95 in the dust removal mechanism 9 is rotated to squeeze the extrusion rod 92 at the bottom, so that the extrusion rod 92 can drive the end extrusion block 94 to move downward. The extrusion rod 92 can drive the end extrusion block 94 to move downward to hit the dustproof net 10. The dust at the bottom is shaken off by the shaking of the dustproof net 10 to prevent affecting the internal heat dissipation.

[0024] In this embodiment, a spoiler mechanism 11 is provided inside the body 1. The spoiler mechanism 11 drives the bent rod 116 on the outer wall to squeeze the outer wall of the fixed rod 114 through the squeezing rod 92, so that the spoiler 115 can be continuously swung to disturb the interior, thereby preventing the internal airflow from blowing in one direction, resulting in the internal part of the body 1 not being cooled.

[0025] The above-mentioned dust removal mechanism 9 includes a fixing plate 91, which is fixedly mounted on the inner wall of the machine body 1.

One end of the return spring 93 is fixedly connected to the outer wall of the extrusion rod 92, and the other end of the return spring 93 is fixedly connected to the bottom wall of the fixing plate 91. The elastic force of the return spring 93 can make the extrusion rod 92 move upward and reset. An extrusion block 94 is fixedly mounted on the end of the extrusion rod 92.

[0027] The fan blade 8 at the end of the rotating rod 7 is driven by the starting motor 6 to rotate to dissipate the heat inside. At the same time, the rotating rod 7 drives the cam 95 to rotate to squeeze the extrusion rod 92 at the bottom, so that the extrusion rod 92 drives the end extrusion block 94 to move downward, and then the extrusion rod 92 is reset by the elastic force of the reset spring 93. Finally, the extrusion rod 92 drives the end extrusion block 94 to continuously move up and down to hit the dustproof net 10, so that the dustproof net 10 is shaken to shake off the dust at the bottom to prevent affecting the internal heat dissipation. At the same time, the extrusion rod 92 drives the bent rod 116 on the outer wall to continuously squeeze the outer wall of the fixed rod 114, so that the fixed rod 114 drives the end spoiler 115 to rotate around the round rod 112, and then the spoiler 115 is swung continuously with the fixed rod 114 through the setting of the torsion spring 113 to disturb the interior, so as to prevent the internal airflow from blowing in one direction, resulting in the internal part of the body 1 not being cooled.
