Description

TECHNICAL FIELD

[0001] The present application belongs to the field of detector device structure design, and particularly relates to a cabin-divided water radon molecule detector. BACKGROUND

[0002] When detecting the radon content in underground water, a water source with stable pressure needs to flow continuously and be in contact with a detection element at an exchange membrane. In the structural design, the water source needs to flow continuously and stably to the exchange membrane to supply the element for detecting radon molecules, and the element outside needs to be protected to avoid damage of the exchange membrane by sand and sundries in the water. Meanwhile, the inhaled water flow needs to be discharged from the detector. SUMMARY

[0003] In view of the problems in the prior art, the present application aims to provide a cabin-divided water radon molecule detector. The structure of the present detector is divided into a water inlet cabin, an exchange cabin, a water pumping cabin and a water discharge cabin along the water flow direction. The water inlet cabin is designed with an element protection cover and a concentrated water inlet hole, which separates large water stones and sundries and guarantees the water inflow. The exchange cabin is designed with a filter sponge which filters the sand and sundries in the water and is also a place for the element to detect the radon content in the water. The water from the concentrated water inlet hole flows into the exchange cabin through the filter sponge and contacts the exchange membrane of the radon detection element, and the radon content in the water is detected through the exchange membrane. A plurality of water flow channels are designed around the exchange membrane, and the water in the exchange cabin is inhaled into the water pumping cabin through the water flow channels. The top of the exchange cabin is connected with the water pumping cabin through a direct insertion micro-rotation structure. The water pumping cabin is installed with a water pump which inhales the water from the concentrated water inlet hole through the channels around the detection element, thereby guaranteeing the stability of the water flow when contacting the exchange membrane. The water discharge cabin is separated from the other three cabins and is only connected with the water outlet of the water pump, and the water is discharged from the detector through the overflow ports uniformly distributed on the circumference of the water discharge cabin. The present application has compact and ingenious structure and complete functions.

[0006] The water inlet cabin is used for filtering coarse particles in the target water source and inputting the filtered water into the downstream end connected exchange cabin;

[0007] The upstream end of the exchange cabin is provided with a micro-particle filter membrane for filtering the input water and entering the inside of the exchange cabin; the radon detection element is used for detecting the water in the exchange cabin; and the water in the exchange cabin flows into the downstream end connected water pumping cabin through the water flow channels;

[0008] The upstream end of the water pumping cabin is provided with a water pump for pumping water in the water pumping cabin into the water draining cabin and forming negative water pressure in the water pumping cabin; the outer wall of the water pump is provided with a groove matched with the water flow channel for making water in the water flow channel flow into the water pumping cabin through the corresponding groove.

[0009] The water draining cabin is used for draining water discharged from the water pumping cabin.

[0010] Further, the water inlet cabin is provided with a plurality of concentrated water inlet holes, each of which is matched with the microparticle filtering membrane, and is used for inputting filtered water in the water inlet cabin into the microparticle filtering membrane.

[0011] Further, the microparticle filtering membrane is a filtering sponge.

[0012] Further, the downstream end of the water draining cabin is an opening, and a plurality of overflow ports are arranged on the sidewall of the downstream end and are used for draining water discharged from the water pumping cabin.

[0013] Further, the bottom of the water pump is provided with a connecting piece for connecting and fixing the matching connecting structure arranged at the downstream end of the exchange cabin.

[0022] The application will be further described in detail below with reference to the accompanying drawings, which are provided for the purpose of explanation and are not intended to limit the scope of the application.

[0023] The water radon detector is immersed in the water source during use. When the water pump is turned on, the water in the water pumping cabin is pumped into the water draining cabin through the overflow port, and negative water pressure is formed in the water pumping cabin, and water flows in through the water flow channel in the exchange cabin. The water is pumped by negative pressure instead of directly pumping water to the exchange membrane of the radon detection element, which ensures smooth water flow and protects the exchange membrane of the radon detection element from water impact.

[0024] After the water pump is turned on, the water flows through the concentrated water inlet hole of the water inlet cabin to the exchange cabin and contacts the exchange membrane of the radon detection element, and the detector detects the radon molecules in the water through the exchange membrane. During this process, the protective cover and the filtering sponge protect the components and filter the water source. The concentrated water inlet hole ensures the entry of water flow. The water flow channel is opened around to ensure the water source at the exchange membrane to flow, so that the detection result is more accurate.
