Description

Technical Field

[0001] The invention belongs to the field of core-pulling water filtering equipment for power plants, and in particular relates to a core-pulling water filtering alarm release and switch-free device for power plants. Background Art

[0002] At present, the water filter is composed of a cylinder, a stainless steel filter, a sewage discharge part, a transmission device and an electrical control part. When working, the water to be filtered enters from the water inlet, flows through the filter, and enters the pipeline required by the user through the outlet for process circulation. The particulate impurities in the water are trapped inside the filter. A water filter is also installed in the water inlet pipe of the power plant.

[0003] However, the existing water filter is not intelligent enough when in use. When the water flow in the water filter is too large, it cannot alarm externally and cannot adjust itself. It needs manual deactivation of the alarm and power-off operation, which is not convenient enough.

[0004] Therefore, there is an urgent need for a core-pulling water filtration alarm release and switch-free device for power plants. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a core-pulling water filter alarm release and switch-free device for a power plant, which solves the problems raised in the above-mentioned background technology by adding a core-pulling filter housing, side clamps, a top plate and a controller.

[0006] The technical solution of the present invention is achieved as follows: a core-pulling water filtration alarm release and switch-free device for a power plant, comprising a core-pulling filter housing, a side clamp, a top plate and a controller, wherein a first solenoid valve and a second solenoid valve are fixed on the left and right sides of the annular side of the core-pulling filter housing, respectively, and two side clamps of equal specifications are provided, and square grooves are penetrated through the left end faces of the two side clamps, and the top plate is fixed to the upper ends of the two side clamps, and a first micro electric telescopic rod and a second micro electric telescopic rod are respectively provided on the lower end faces of the top plate, and a connecting plate is laterally fixed to the lower end faces of the first micro electric telescopic rod and the second micro electric telescopic rod, and the controller is arranged on the left side of the upper end face of the top plate, and an alarm horn is arranged on the upper end face of the controller.

[0007] As a preferred embodiment, the distance sensor is arranged through the left end of the upper annular side of the core-pulling filter housing, the push rod is arranged through the middle of the upper annular side of the core-pulling filter housing, the arc baffle is arranged horizontally inside the core-pulling filter housing, and the arc baffle is fixed in the middle of the lower end face of the push rod, and the longitudinal support rod is arranged on the left and right sides inside the core-pulling filter housing.

[0008] As a preferred embodiment, the fixed block is welded to the lower side of the annular side of the two longitudinal support rods, the floating block is movably sleeved on the lower side of the annular side of the two longitudinal support rods, and the two floating blocks are movably located on the upper end surfaces of the two fixed blocks, and the distance sensor is located directly above the left floating block.

[0009] As a preferred embodiment, the connecting plate is fixedly connected to the upper end surface of the push rod, and the first micro electric telescopic rod, the second micro electric telescopic rod, the first solenoid valve, the second solenoid valve, the alarm horn and the distance sensor are all electrically connected to the controller through wires.

[0010] As a preferred embodiment, the threaded hole is opened through the lower end surface of the two square grooves, the screw is set in the two threaded holes, the rotating handle is set on the lower end surface of the two screws, the bearing and the arc-shaped block are set on the upper end surface of the two screws, the side rubber block is set on the front and rear end surfaces of the two square grooves, the multiple telescopic springs are equidistantly set on the upper end surface of the two square grooves, and the spring connecting plate is set on the lower end surfaces of multiple telescopic springs.

[0011] As a preferred embodiment, the left and right ends of the core-pulling filter housing respectively penetrate through the two square grooves, and the spring connecting plate is fixedly connected to the upper sides of the left and right ends of the core-pulling filter housing, and a plurality of side rubber blocks are attached to the left and right ends of the annular side of the core-pulling filter housing, and the arc-shaped clamping block is fixedly connected to the lower sides of the left and right ends of the core-pulling filter housing.

[0012] After adopting the above technical scheme, the beneficial effect of the present invention is as follows: when the water level inside the core-pulling filter housing rises, the two floating blocks both float and rise on the annular side of the longitudinal support rod, so that the floating block on the left rises and approaches the distance sensor. The distance sensor detects the rising floating block and feeds back to the controller for processing. The controller controls the alarm horn to sound an alarm. At the same time, the controller controls the first micro-electric telescopic rod and the second micro-electric telescopic rod to extend downward. The first micro-electric telescopic rod and the second micro-electric telescopic rod push the arc baffle downward through the connecting plate and the push rod, so that the arc baffle moves toward the water inlet at the lower end of the core-pulling filter housing, so that the water flow at the water inlet at the lower end of the core-pulling filter housing can be reduced. At the same time, the controller controls the first solenoid valve and the second solenoid valve to close the left and right ends of the core-pulling filter housing. When the water flow inside the core-pulling filter housing becomes smaller, the floating block will drop with the liquid level. The distance sensor detects the drop of the floating block and feeds back to the controller for processing. The controller controls the alarm horn to close.

[0013] When it is necessary to adjust the height of the core-pulling filter housing, turn the two rotating handles respectively, and the two screws will move accordingly, so that the two arc-shaped blocks will press the core-pulling filter housing upward under the action of the bearings and move upward accordingly, and the spring connecting plate will move upward accordingly, and the multiple telescopic springs will retract. The multiple side rubber blocks can prevent the core-pulling filter housing from shaking when it moves up and down, thereby facilitating the adjustment of the height of the core-pulling filter housing.
