Detailed Description

The present invention will be described in further detail with reference to the following detailed description and accompanying drawings.

Referring to fig. 1 and 2, an integrated prefabricated cutoff pumping station is shown.

The pump station comprises pump station basis 1, square barrel 2, water inlet pipe 3, outlet pipe 4 and parts such as sewage elevator pump 5, saves traditional level sensor.

The square cylinder 2 has a cylinder front wall 21, a cylinder left wall 22, a cylinder rear wall 23, and a cylinder right wall 24. The cylinder front wall 21, the cylinder left wall 22, the cylinder rear wall 23 and the cylinder right wall 24 together define a cylinder built-in space. The water inlet pipeline 3 is fixed on the left wall 22 of the cylinder body. The water outlet pipeline 4 is fixed on the right wall 24 of the cylinder body. The sewage lift pump 5 is disposed inside the cylinder built-in space.

The front wall 21 of the cylinder is provided with a front wall glass window 210. The barrel left wall 22 has a left wall glass window 220. The barrel back wall 23 has a back wall glass window 230 therebetween. The right barrel wall 24 has a right wall glass window 240.

The liquid level condition of the inner space of the cylinder can be observed from the outside through any one of the front wall glass window 210, the left wall glass window 220, the rear wall glass window 230 and the right wall glass window 240.

Preferably, an image pickup device 6 is disposed outside one of the front wall glass window 210, the left wall glass window 220, the rear wall glass window 230, and the right wall glass window 240. As can be seen from fig. 2, the camera device 6 is arranged in front of the front glass window 210 in this embodiment. The imaging lens of the imaging apparatus 6 faces backward. The camera device 6 shoots the liquid level condition of the inner space of the cylinder through the front wall glass window 210. For better recording, the camera device 6 may be equipped with a night vision module or a flash module, and may also be equipped with an illumination light source in the space inside the cylinder. The image pickup apparatus 6 corresponds to an external monitor screen. The camera device 6 transmits the photographed image information to the external monitor screen in real time. Therefore, a technician can observe the liquid level condition in the built-in space of the cylinder through the external monitoring screen. The image pickup apparatus 6 is a commercially available product, such as a smart camera for monitoring that is used on the market. The external monitoring screen can be a computer screen or a mobile phone screen. The camera device 6 and the external monitor screen may be wired or wirelessly transmitted. Since the camera device 6 is arranged outside the square cylinder 2, it is not subject to any corrosion and erosion of the sewage in the built-in space of the cylinder, i.e. the working life of the camera device 6 for observing the liquid level is not affected.

In addition to the level observable by the camera device 6, it is also possible to provide: a front wall transparent electrode 2101 is arranged outside the front wall glass window 210. And a left wall transparent electrode 2201 is arranged outside the left wall glass window 220. A rear wall transparent electrode 2301 is disposed outside the rear wall glass window 230. And a right wall transparent electrode 2401 is arranged outside the right wall glass window 240. The front wall transparent electrode 2101, the left wall transparent electrode 2201, the rear wall transparent electrode 2301 and the right wall transparent electrode 2401 are in the same horizontal plane, and the horizontal plane is a liquid level warning surface at the same time. And if the liquid level of the built-in space of the cylinder is higher than the horizontal plane, alarming and prompting are required.

The front wall transparent electrode 2101, the front wall glass window 210 and a medium opposite to the front wall transparent electrode 2101 in the built-in space of the cylinder form a front wall capacitor together. When the liquid level in the barrel built-in space is lower than the horizontal plane, the medium in the barrel built-in space opposite to the front wall transparent electrode 2101 is air. When the liquid level in the built-in space of the cylinder is higher than the horizontal plane, the medium in the built-in space of the cylinder, which is opposite to the front wall transparent electrode 2101, is sewage. The conductivity of the sewage is stronger than that of the air. Therefore, the capacity of the front wall capacitor when the liquid level of the cylinder built-in space is higher than the horizontal plane is larger than the capacity of the front wall capacitor when the liquid level of the cylinder built-in space is lower than the horizontal plane.

The left wall transparent electrode 2201, the left wall glass window 220 and the medium opposite to the left wall transparent electrode 2201 in the space inside the cylinder jointly form a left wall capacitor. When the liquid level in the space inside the cylinder is lower than the horizontal plane, the medium opposite to the left wall transparent electrode 2201 in the space inside the cylinder is air. When the liquid level of the space in the cylinder is higher than the horizontal plane, the medium opposite to the left wall transparent electrode 2201 in the space in the cylinder is sewage. The conductivity of the sewage is stronger than that of the air. Therefore, the capacity of the left wall capacitor when the liquid level of the space in the cylinder is higher than the horizontal plane is larger than the capacity of the left wall capacitor when the liquid level of the space in the cylinder is lower than the horizontal plane.

The rear wall transparent electrode 2301, the rear wall glass window 230 and the medium opposite to the rear wall transparent electrode 2301 in the cylinder built-in space form a rear wall capacitor together. When the liquid level in the cylinder built-in space is lower than the horizontal plane, the medium in the cylinder built-in space opposite to the rear wall transparent electrode 2301 is air. When the liquid level of the built-in space of the cylinder is higher than the horizontal plane, the medium in the built-in space of the cylinder opposite to the rear wall transparent electrode 2301 is sewage. The conductivity of the sewage is stronger than that of the air. Therefore, the capacity of the rear wall capacitor when the liquid level of the space in the cylinder is higher than the horizontal plane is larger than the capacity of the rear wall capacitor when the liquid level of the space in the cylinder is lower than the horizontal plane.

The right wall transparent electrode 2401, the right wall glass window 240 and a medium opposite to the right wall transparent electrode 2401 in the barrel built-in space form a right wall capacitor together. When the liquid level in the cylinder built-in space is lower than the horizontal plane, the medium in the cylinder built-in space opposite to the right wall transparent electrode 2401 is air. When the liquid level in the built-in space of the cylinder is higher than the horizontal plane, the medium in the built-in space of the cylinder, which is opposite to the front wall transparent electrode 2101, is sewage. The conductivity of the sewage is stronger than that of the air. Therefore, the capacity of the right wall capacitor when the liquid level of the space in the cylinder is higher than the horizontal plane is larger than the capacity of the right wall capacitor when the liquid level of the space in the cylinder is lower than the horizontal plane.

And designing a liquid level alarm circuit by utilizing the characteristics of the front wall capacitor, the left wall capacitor, the rear wall capacitor and the right wall capacitor.

The liquid level alarm circuit is arranged outside the square cylinder 2. Referring to fig. 3, the liquid level alarm circuit has four capacitance capacity detecting units, an and gate unit 75 and an alarm unit 76.

The four capacitance capacity change detection units are respectively used for detecting and judging whether the capacitance capacities of the front wall capacitor, the left wall capacitor, the rear wall capacitor and the right wall capacitor are increased or not. The and gate unit 75 is configured to output an alarm on signal or an alarm off signal to the alarm unit 76 according to the determination results of the four capacitance capacity change detection units.

The capacitance capacity change detection unit may be composed of an ac power supply 71, a voltage dividing capacitor 72, a rectifying unit 73, and a voltage comparator 74. The ac power supply 71 supplies power to the front wall capacitor (the left wall capacitor, the rear wall capacitor, or the right wall capacitor) through the voltage dividing capacitor 72. The voltage at the front wall capacitor (the left wall capacitor, the rear wall capacitor, or the right wall capacitor) is rectified by the rectifying unit 73 and then compared with a reference voltage by the voltage comparator 74. When the capacitance capacity of the front wall capacitor (the left wall capacitor, the rear wall capacitor, or the right wall capacitor) increases, the voltage is greater than the reference voltage, and the voltage comparator 74 outputs a high level; the capacitance capacity of the measurement capacitor is not increased, the voltage is smaller than the reference voltage, and the voltage comparator 74 outputs a low level.

And in a default state, the liquid level of the built-in space of the cylinder body is lower than the horizontal plane. When the capacities of the front wall capacitor, the left wall capacitor, the rear wall capacitor and the right wall capacitor are increased, the fact that the liquid level of the built-in space of the cylinder is higher than the horizontal plane is indicated, and the AND gate unit outputs an opening signal to the alarm unit. And if the capacity of any one of the front wall capacitor, the left wall capacitor, the rear wall capacitor and the right wall capacitor is not increased, that is, the liquid level of the built-in space of the cylinder is lower than the horizontal plane is indicated, and the AND gate unit outputs a disconnection signal to an alarm unit. If at least one of the front wall capacitor, the left wall capacitor, the rear wall capacitor and the right wall capacitor is not increased in capacity, the increase in capacity indicates that the liquid level of the space in the cylinder is adjacent to the horizontal plane and the liquid level shakes, and the situation is a false alarm but not a warning, and the AND gate unit outputs a disconnection signal to the warning unit. The purpose of setting the front wall capacitor, the left wall capacitor, the rear wall capacitor and the four detection capacitors of the right wall capacitor is to avoid the occurrence of false alarm.

The dual-purpose glass is made in this embodiment, and the mode of the liquid level condition in barrel built-in space is realized to the transparent characteristic (camera equipment) of both utilizing glass, and the nonconducting characteristic (electric capacity) of utilizing glass again to two kinds of differences.
