Description

Technical Field

[0001] This utility model relates to the field of particle detector technology, and in particular to a suspended particle detector. Background Technology

[0002] A suspended particle detector is an instrument used to detect the quantity, size, shape, distribution, and other characteristics of suspended particles in a liquid. Its working principle is based on a variety of physical and optical phenomena. When a light beam passes through a liquid containing suspended particles, the particles scatter the light. By detecting the intensity and angle of the scattered light, the size and concentration of the particles can be inferred. According to the Mie scattering theory, a quantitative relationship between light scattering intensity and particle size can be established, thereby enabling the detection of particle size.

[0003] In shallow water storage, online turbidimeters are commonly used to detect solid particles in the water, thereby assessing the water's condition. However, when turbidimeters use sensors to detect particles in the water, the sensors rely on light for detection. When the illuminance in the water is strong, it may affect the scattering of light. Furthermore, in turbulent water environments, particles can disperse and interfere with light propagation, leading to errors in the detection results. Therefore, a suspended particle detector is proposed. Utility Model Content

[0026] Example

[0027] Reference Figures 1-3 As an embodiment of the present invention, a suspended particulate detector is provided, comprising: a detection unit 100 and a blocking unit 200;

[0028] The detection unit 100 includes a controller 101 and a turbidity sensor 102, which are fixedly connected by a cable 103.

[0029] The sealing unit 200 includes a transparent cover 201 fixedly connected to one end of the turbidity sensor 102. A reinforcing tube 202 is fixedly sleeved on the outer wall of the transparent cover 201. A cylindrical cover 203 is fixedly sleeved on the outer wall of the transparent cover 201. One end of the reinforcing tube 202 is fixedly connected to the outside of the cylindrical cover 203. A straight tube 204 is fixedly connected to the bottom end of the cylindrical cover 203. An electric telescopic rod 205 is fixedly installed on the top of the inner cavity of the cylindrical cover 203. A lifting plate 206 is fixedly connected to the bottom of the output end of the electric telescopic rod 205. A sealing ring 207 is fixedly connected to the top of the lifting plate 206.

[0030] The turbidity sensor 102 is installed in the shallow water storage tank and is located below the water surface. The controller 101 controls the turbidity sensor 102 to perform detection through the cable 103. A laser emitter is set at the end of the turbidity sensor 102 facing the transparent cover 201. The interior of the transparent cover 201 is hollow, and the end of the transparent cover 201 penetrates the cylindrical cover 203 so that the laser can irradiate into the cylindrical cover 203. The end of the transparent cover 201 inside the cylindrical cover 203 is an arc surface that fits the inner wall of the cylindrical cover 203 so that it will not block the lifting plate 206 from rising and falling. The diameter of the transparent cover 201 is the same as the diameter of the turbidity sensor 102.

[0031] The inner wall of the reinforcing tube 202 is fixedly connected to the outer wall of the turbidity sensor 102. The reinforcing tube 202 is used to reinforce the connection between the transparent cover 201 and the cylindrical cover 203. The electric telescopic rod 205 can work underwater. The electric telescopic rod 205 is used to drive the lifting plate 206 to slide in the inner cavity of the cylindrical cover 203. The sealing ring 207 is used to increase the sealing between the lifting plate 206 and the inner wall of the cylindrical cover 203. When no detection is required, the lifting plate 206 is close to the bottom of the cylindrical cover 203 so that the lifting plate 206 blocks the end of the straight tube 204 and prevents water from entering the cylindrical cover 203. When the cylindrical cover 203 is at a specified depth, the electric telescopic rod 205 pulls the lifting plate 206 away from the straight tube 204 so that the water passes through the straight tube 204 and is drawn into the cylindrical cover 203.

[0032] Both the cylindrical cover 203 and the reinforcing pipe 202 are coated with an opaque coating to reduce reflections in the water. When water enters the cylindrical cover 203, the water body does not experience large-scale fluctuations, thus enabling the turbidity sensor 102 to accurately detect the water in the reservoir. After the detection is completed, the electric telescopic rod 205 pushes the lifting plate 206 to squeeze the water in the cylindrical cover 203 out through the straight pipe 204.

[0033] In addition, a conical cover 208 is fixedly connected to the bottom end of the straight tube 204, and multiple through holes arranged in a ring array are opened on the side wall of the straight tube 204.

[0034] The conical shroud 208 expands in a trumpet shape. When the electric telescopic rod 205 drives the lifting plate 206 away from the straight pipe 204, a negative pressure is generated inside the cylindrical shroud 203 to draw water from outside the cylindrical shroud 203 into the cylindrical shroud 203. During the water pumping process, water near the straight pipe 204 can be drawn into the cylindrical shroud 203 through the conical shroud 208 and the through hole, thereby avoiding the straight pipe 204 from collecting water from a local area in the water storage tank. By increasing the collection range, the detection results are made consistent with the actual situation.

[0035] Specifically, the bottom of the lifting plate 206 is fixedly connected to a round rod 209 that passes through the straight tube 204. The bottom end of the round rod 209 is fixedly connected to a rubber plug 210. The rod surface of the round rod 209 is fixedly connected to multiple conical spikes 211. A gap is left between the conical spikes 211 and the inner wall of the straight tube 204.

[0036] The diameter of the rubber stopper 210 is equal to the inner diameter of the straight tube 204. When the lifting plate 206 rises to its limit, the round rod 209 drives the rubber stopper 210 to be inserted into the straight tube 204, thereby sealing the straight tube 204. This prevents the water in the cylindrical cover 203 from flowing through the straight tube 204 during the detection process of the turbidity sensor 102, thus maintaining the stability of the water and improving the accuracy of the detection. In some water bodies, microorganisms and algae may be present, which may cause bubbles to form. The conical spike 211 can puncture the bubbles to avoid affecting the reflection of the laser. During the process of the lifting plate 206 driving the round rod 209 to rise and fall, the conical spike 211 will not scratch the inner wall of the straight tube 204.

[0037] Furthermore, a flexible hose 212 is fixedly connected to the side wall of the cylindrical cover 203, and a one-way valve 213 is sleeved on the wall of the flexible hose 212.

[0038] The one-way valve 213 prevents water from flowing into the hose 212 within the cylindrical cover 203. The electric telescopic rod 205 moves the lifting plate 206 away from the straight pipe 204, allowing clean water to be supplied into the hose 212. The clean water in the hose 212 passes through the one-way valve 213 and enters the cylindrical cover 203 to flush its interior. The rubber stopper 210 blocks the straight pipe 204, preventing water from flowing into the cylindrical cover 203. After flushing, the lifting plate 206 is lowered to discharge the clean water from the cylindrical cover 203 through the straight pipe 204, thus ensuring the cleanliness of the interior of the cylindrical cover 203.

[0039] Furthermore, a threaded tube 214 is fixedly connected to the top of the cylindrical cover 203, and a sealing sleeve 215 is threaded onto the top of the threaded tube 214.

[0040] The sealing sleeve 215 is used to seal the opening of the threaded pipe 214. When some water passes through the side wall of the lifting plate 206 and flows to the side of the lifting plate 206 near the electric telescopic rod 205, the sealing sleeve 215 is rotated off to discharge the water remaining in the cylindrical cover 203 through the threaded pipe 214. After discharge, the sealing sleeve 215 is re-fixed to the threaded pipe 214, thereby preventing the electric telescopic rod 205 from being damaged due to prolonged contact with water.

[0041] During use, the turbidity sensor 102 is placed in a shallow water storage tank. When detection is required, the cylindrical cover 203 is lowered to a specified depth in the water storage tank. Then, the electric telescopic rod 205 pulls the lifting plate 206 away from the straight pipe 204, allowing water to pass through the straight pipe 204 and be drawn into the cylindrical cover 203. The conical cover 208 and the through hole can draw water near the straight pipe 204 into the cylindrical cover 203 to increase the collection range. The conical spike 211 can puncture air bubbles to avoid affecting the reflection of the laser. When the lifting plate 206 rises to its limit, the rubber stopper 210 can seal the straight pipe 204 to maintain the stability of the water in the cylindrical cover 203. The cylindrical cover 203 reduces the reflection in the water, thereby enabling the turbidity sensor 102 to accurately detect the water in the water storage tank.

[0042] After the inspection is completed, the electric telescopic rod 205 pushes the lifting plate 206, causing it to move towards the straight pipe 204 to squeeze out the water in the cylindrical cover 203 through the straight pipe 204. When cleaning is required, the electric telescopic rod 205 moves the lifting plate 206 away from the straight pipe 204, and then clean water is delivered into the hose 212 to flush the inside of the cylindrical cover 203. After rinsing, the lifting plate 206 is lowered to discharge the clean water in the cylindrical cover 203 through the straight pipe 204. When some water passes through the lifting plate 206 and flows to the side of the lifting plate 206 near the electric telescopic rod 205, the sealing sleeve 215 is rotated out to discharge the remaining water in the cylindrical cover 203 through the threaded pipe 214.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
