Technical Field

[0001] The present application relates to the field of detection devices, and in particular to a detection device for a float water level controller. Background Art

[0002] The float water level controller, also known as the float liquid level switch, is a device that uses the buoyancy of the float in the liquid to detect water level changes. The float water level controller in the prior art mainly detects the on and off of the float water level controller by manually driving the float to rotate to simulate the floating of the float.

[0003] However, the detection is performed by manually rotating the float, which results in low detection efficiency and accuracy of the float water level controller. Summary of the invention

[0006] By adopting the above technical scheme, when the float water level controller performs on-off angle detection, the staff places the float on the clamping assembly, and the clamping assembly clamps the surface of the float to achieve the limit of the float on the turntable; the staff presses the detection plate to drive the detection plate to rotate in the direction away from the detection cavity, and at the same time, the ends of the wires on the float are embedded in the detection cavity one by one, and the detection plate is released. The elastic force of the elastic member drives the detection plate to rotate in the direction close to the detection cavity, and the detection plate surface and the inner wall of the detection cavity clamp the ends of the wires to form a limit. The PLC detects the on-off state of the wires in each detection cavity in real time, drives the turntable to rotate on the surface of the frame, and drives the float to rotate. When the PLC detects that the wire is disconnected, it records the rotation angle of the float, compares the on-off angle of the float with the qualified angle range, and determines whether the on-off angle of the float is qualified, thereby improving the detection efficiency and detection accuracy of the float water level controller.

[0028] The following is combined with Figure 1-5 This application is described in further detail.

[0029] An embodiment of the present application discloses a detection device for a float water level controller.

[0030] Example 1 Reference Figure 1 A detection device for a float water level controller includes a frame 1, a turntable 2, a clamping assembly 3 and a detection assembly 4. The bottom of the frame 1 abuts the ground to form a support, the turntable 2 is rotatably connected to the surface of the frame 1, the rotation axis of the turntable 2 and the width direction of the frame 1 are parallel to each other, the clamping assembly 3 is installed on the turntable 2, the clamping assembly 3 can clamp the float 5, the detection assembly 4 is installed on the frame 1, and the detection assembly 4 can detect the opening and closing state of the wire on the float 5 in real time, without the need for the staff to manually drive the float 5 to rotate, to achieve accurate measurement of the angle of the disconnection state of the float water level controller, thereby improving the detection efficiency and detection accuracy of the float water level controller.

[0031] Reference Figure 1 The detection assembly 4 includes a PLC 41, a detection seat 42, a servo motor 7, an encoder, multiple elastic members 43 and multiple detection plates 44. The detection seat 42 is fixed to the surface of the frame 1 by bolts. The top surface of the detection seat 42 is provided with multiple detection cavities 421 for the wires on the float 5 to be embedded. The arrangement direction of the detection cavity 421 is parallel to the length direction of the frame 1. The detection plate 44 corresponds to the detection cavity 421 one by one. The detection plate 44 is rotatably connected to the inner wall of the detection cavity 421. The rotation axis of the detection plate 44 is parallel to the length direction of the frame 1. The end of the detection plate 44 facing the detection cavity 421 and the inner wall of the detection cavity 421 can clamp the end of the wire to form a limit, thereby achieving the limit stability of the end of the wire in the detection cavity 421.

[0032] Reference Figure 1 The elastic member 43 can be a compression spring or a tension spring. In the embodiment of the present application, the elastic member 43 is a compression spring with a certain deformation ability. One end of the elastic member 43 in the elastic direction is connected to the surface of the detection plate 44, and the other end of the elastic member 43 in the elastic direction is connected to the surface of the detection seat 42. The elastic member 43 has elastic force to drive the detection plate 44 to rotate in the direction close to the detection cavity 421. The surface of the detection plate 44 and the inner wall of the detection cavity 421 tend to clamp the end of the wire, so that the wire is not easy to escape from the detection cavity 421, thereby improving the limit stability of the wire in the detection cavity 421; PLC41 is fixed to the top surface of the frame 1 by bolts, and PLC41 can detect the on and off status of the wires in each detection cavity 421 in real time.

[0033] Reference Figure 1 and Figure 2The servo motor 7 is fixed to the surface of the frame 1 away from the turntable 2 by bolts. The motor axis of the servo motor 7 coincides with the axis of the turntable 2. The end of the motor shaft of the servo motor 7 passes through the outer wall of the frame 1 and is coaxially connected to the rotating shaft of the turntable 2. The encoder is installed between the servo motor 7 and PLC41. The encoder can transmit the rotation angle of the servo motor 7 to PLC41, so that PLC41 can accurately record the on-off angle of the float 5, thereby improving the detection accuracy of the float water level controller.

[0034] Reference Figure 1 The clamping assembly 3 includes a rotating cylinder 31 and a clamping cylinder 32. The rotating cylinder 31 is fixed to the disk surface of the turntable 2 facing the detection seat 42 by bolts. The axis of the rotating cylinder 31 and the axis of the turntable 2 are perpendicular to each other. The base of the clamping cylinder 32 is connected to the piston rod of the rotating cylinder 31. The rotating cylinder 31 can drive the clamping cylinder 32 to rotate. The clamping cylinder 32 has two clamping ends. The end faces of the two clamping ends facing each other are connected with clamping plates 6. When the two clamping ends are close to each other, the two clamping plates 6 clamp the two sides of the float 5 to form a limit, thereby realizing the limit of the float 5 on the clamping cylinder 32.

[0035] Reference Figure 1 When the turntable 2 rotates on the surface of the frame 1, it drives the float 5 to rotate. When the PLC 41 detects that the wire in the detection chamber 421 is in a disconnected state, the rotation angle of the float 5 is recorded, and the rotation angle of the float 5 is compared with the qualified angle range, so as to determine whether the on-off angle of the float 5 is qualified, thereby realizing accurate detection of the float water level controller.

[0036] Reference Figure 1 The frame 1 is provided with a limit assembly 8, which can limit the electric wire on the float 5. The limit assembly 8 includes a limit seat 81, a fixed seat 82 and a limit rod 83. The limit seat 81 and the fixed seat 82 are fixed to the surface of the frame 1 by bolts at intervals. A limit space 811 for the power line to pass through is reserved between the limit seat 81 and the fixed seat 82. The limit rod 83 is slidably connected to the top surface of the limit seat 81. The sliding direction of the limit rod 83 is parallel to the length direction of the frame 1. The limit seat 81 is fixed to the limit cylinder 9 by bolts. A limiting cavity 812 is provided on the surface of the limiting seat 81 for the limiting cylinder 9 to be embedded in. The inner wall of the limiting cavity 812 is pressed against the outer wall of the limiting cylinder 9 to form a limit, so that the limiting cylinder 9 is not easy to separate from the limiting seat 81, thereby improving the limiting stability of the limiting cylinder 9 on the limiting seat 81. The axis of the piston rod of the limiting cylinder 9 coincides with the sliding direction of the limiting rod 83, and the end of the piston rod of the limiting cylinder 9 is coaxially fixed to the end of the limiting rod 83. A limiting groove is provided on the surface of the fixing seat 82 facing the limiting space 811 for the end of the limiting rod 83 to be embedded in.

[0037] Reference Figure 1When the clamping cylinder 32 drives the clamping ends to approach each other, the two clamping plates 6 clamp the two sides of the float 5 to form a limit. At the same time, the wires on the float 5 pass through the limit space 811 and are embedded in the detection cavity 421 one by one. The elastic force of the elastic member 43 drives the detection plate 44 to rotate in the direction close to the detection cavity 421. The surface of the detection plate 44 and the inner wall of the detection cavity 421 clamp the ends of the wires to form a limit, thereby fixing the ends of each wire on the float 5; at the same time, the limit cylinder 9 drives the limit rod 83 to slide in the direction close to the limit groove, and the end of the limit rod 83 is embedded in the limit groove. The outer peripheral surface of the limit rod 83 is pressed against the inner wall of the limit groove to form a limit and limit the wires in the limit space 811, so that when the float 5 rotates around the axis of the turntable 2, the wires are not easy to escape from the limit space 811, thereby improving the limit stability of the wire ends in the detection cavity 421.

[0038] The implementation principle of the detection device of a float water level controller in Example 1 of the present application is as follows: the clamping cylinder 32 drives the clamping ends to approach each other, and the two clamping plates 6 clamp the two sides of the float 5 to form a limit. At the same time, the wires on the float 5 pass through the limit space 811 and are embedded in the detection cavity 421 one by one. The elastic force of the elastic member 43 drives the detection plate 44 to rotate in the direction close to the detection cavity 421, and the plate surface of the detection plate 44 and the inner wall of the detection cavity 421 clamp the ends of the wires to form a limit, thereby fixing the ends of each wire on the float 5; at the same time, the limit cylinder 9 drives the limit rod 83 to slide in the direction close to the limit groove, and the end of the limit rod 83 is embedded in the limit groove, and the outer peripheral surface of the limit rod 83 is pressed against the limit The inner wall of the groove forms a limit and limits the wire to the limit space 811, so that when the float 5 rotates around the axis of the turntable 2, the wire is not easy to escape from the limit space 811, thereby improving the limit stability of the wire end in the detection chamber 421; at the same time, the servo motor 7 drives the turntable 2 to rotate, driving the float 5 to rotate around the turntable 2. When the PLC41 detects that the wire in the detection chamber 421 is in a disconnected state, the encoder transmits the rotation angle of the motor to the PLC41, and the PLC41 compares the rotation angle of the float 5 with the qualified angle range to determine whether the on-off angle of the float 5 is qualified. There is no need for the staff to manually drive the float 5 to rotate, thereby realizing accurate detection of the float water level controller.

The clamping assembly 10 includes a connecting rod 101, a slider 102, an inflatable piston 103, an elastic member 104 and two clamping airbags 105. The material of the clamping airbags 105 can be rubber or silicone. In the embodiment of the present application, the material of the clamping airbags 105 is rubber, which has a certain deformation ability. The clamping airbags 105 correspond to the clamping plates 6 one by one. The clamping airbags 105 are installed on the surfaces of the clamping plates 6 that are opposite to each other. The surfaces of the clamping airbags 105 can be clamped against the bottom of the float 5 to form a limit. A sliding cavity 61 for the sliding of the slider 102 is opened on the plate surface of one of the clamping plates 6 facing the other clamping plate 6.

In the embodiment of the present application, the elastic member 104 is a compression spring with a certain deformation ability. One end of the elastic member 104 in the elastic force direction is connected to the inner wall of the inflatable flow channel 62, and the other end of the elastic member 104 in the elastic force direction is connected to the surface of the inflatable piston 103. The elastic member 104 has the elastic force to drive the inflatable piston 103 to slide in the direction close to the sliding chamber 61, and the end of the inflatable piston 103 tends to protrude from the inner wall of the sliding chamber 61.

When the electromagnet 113 is energized and has magnetic force, the electromagnet 113 and the magnetic block 112 repel each other with the same poles, and drive the positioning piston 114 to slide away from the positioning cavity 63. The end of the positioning piston 114 protruding from the clamping plate 6 abuts against the end of the float 5 to form a limit, and the airbag 105 and the positioning piston 114 abut against the two ends of the float 5 in the length direction to form a limit, so that the float 5 is not easy to separate from the clamping plate 6, thereby improving the limiting stability of the clamping plate 6 on the float 5.

The buffer surface 1211 can press against the surface of the positioning piston 114 and guide the power piston 121 to slide in the direction close to the second inflation channel 64; when the positioning piston 114 slides in the direction away from the positioning cavity 63, the buffer surface 1211 presses against the surface of the positioning piston 114 and guides the power piston 121 to slide in the direction close to the second inflation channel 64, and the end of the power piston 121 is flush with the inner wall of the positioning cavity 63. At the same time, the second inflation channel 64 is connected to press against the inner cavity of the airbag 105, and the air in the second inflation channel 64 enters the inner cavity of the airbag 105, pressurizes and expands against the surface of the airbag 105, and presses against the surface of the float 5 to form a limit, thereby further improving the limit stability of the float 5 between the two clamping plates 6.

[0046] The implementation principle of the detection device of a float water level controller of Example 2 of the present application is as follows: when the float 5 is placed between the two clamping plates 6, the clamping cylinder 32 drives the two clamping plates 6 to approach each other, and the connecting rod 101 rotates, driving the slider 102 to slide along the inner wall of the sliding chamber 61 toward the direction close to the inflation channel 1 62, and the guide surface 1031 abuts against the surface of the slider 102 and guides the inflation piston 103 to slide toward the direction close to the inflation channel 1 62, and the end of the inflation piston 103 is flush with the inner wall of the sliding chamber 61, and at the same time, the inflation channel 1 62 is connected to the inner cavity of the airbag 105, and the air in the inflation channel 1 62 enters the inner cavity of the airbag 105, pressurizes and expands the surface of the airbag 105 and forms a limit against the surface of the float 5, further improving the limit stability of the float 5 between the two clamping plates 6; and the contact switch 111 abuts against the slider 102 and is turned on, and the electromagnet 113 is energized and has magnetism, The electromagnet 113 and the magnetic block 112 repel each other with the same poles, and drive the positioning piston 114 to slide in the direction away from the positioning cavity 63. The end of the positioning piston 114 protruding from the clamping plate 6 abuts against the end of the floating ball 5 to form a limit, and the air bag 105 and the positioning piston 114 abut against the two ends of the length direction of the floating ball 5 to form a limit, so that the floating ball 5 is not easy to separate from the clamping plate 6, thereby improving the limiting stability of the clamping plate 6 on the floating ball 5; the buffer surface 1211 abuts against the surface of the positioning piston 114 and guides the power piston 121 to slide in the direction close to the second inflation flow channel 64, and the end of the power piston 121 is flush with the inner wall of the positioning cavity 63. At the same time, the second inflation flow channel 64 is connected to the inner cavity of the air bag 105, and the air in the second inflation flow channel 64 enters the inner cavity of the air bag 105, pressurizes and expands against the surface of the air bag 105, and forms a limit against the surface of the floating ball 5, further improving the limiting stability of the floating ball 5 between the two clamping plates 6.

Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
