Abstract
The utility model relates to a following current quality of water synchronous sample thief, including a jar body and its characterized in that of haulage rope that entries, jar body is two open-ended barrel, and it has the check valve that entries to embed in water inlet department, has put out water check valve outside water outlet department, sets up the guide plate in the lower part of jar body, is connected with out water haulage rope in water outlet department. The utility model has the advantages of simple structure and accurate section sampling.
Description
Technical Field
The utility model belongs to the environmental monitoring field relates to a water quality sampler for the water sampling that has the flow if: a sewage outlet of a river, a discharge outlet of a river, a sewage treatment plant and the like.
Background
Traditional water quality sampler is vertical water quality sampler, arranges the sample thief in the aquatic and gushes into the jar body with water from around through the gravity of the sample thief jar body and the effort of water, and to the water that has certain flow of collection, vertical type sample thief is at the collection in-process, and the jar body is gushed into from around to quality of water to accomplish the quality of water sampling. The water quality sampler can collect water quality at a certain position at a certain time point, but the water quality sampling of a certain section is difficult to obtain.
SUMMERY OF THE UTILITY MODEL
The instantaneous quality of water of definite position and the degree of depth is flowed through for more accurate acquisition required time quantum, the utility model provides a simple structure, the operation of being convenient for, the high following current quality of water synchronous sampling ware of the degree of accuracy. The utility model discloses a synchronous sample thief of following current quality of water can overcome the drawback of upright quality of water sample thief, arranges the synchronous sample thief of following current in the aquatic and directly cuts the sampling to flowing through jar body rivers, and certain sectional quality of water flows through to more accurate collection required time quantum. The technical scheme is as follows:
a synchronous sampler for water quality in forward flow comprises a tank body and a water inlet hauling rope, and is characterized in that a guide plate is arranged at the lower part of the tank body, the tank body is a cylinder with openings on two sides, a water inlet check valve is arranged in the water inlet, a water outlet check valve is arranged outside the water outlet, and the water outlet hauling rope is connected with the water outlet.
Preferably, the guide plate is a streamline plate, and the width of the plate is gradually increased from the front end to the rear end. A counterweight is arranged on the guide plate or the lower part of the tank body. The water inlet of the tank body is in a conical shape with a smaller opening. The two sides of the tank body are provided with balance plates 3. And a water flow sensor is arranged on the outer side of the tank body.

Detailed Description
The utility model discloses a synchronous sample thief of following current quality of water mainly includes: the water-saving tank comprises a cylindrical tank body 1, a guide plate 2, a water inlet one-way valve 4 arranged in a water inlet, a water outlet one-way valve 5 arranged outside a water outlet, a water flow sensor (arranged outside the tank body and not shown), two side balance plates 3, a water inlet traction rope 7, a water outlet traction rope 8 and a stainless steel weight used as a balance weight 6. The utility model adopts a check valve with a circular folded plate which is formed by sealing and connecting two semicircular plates.
The working principle is as follows: draw into water haulage rope and slowly arrange the sample thief in the aquatic, the guide plate is under the effect of rivers, make conical water inlet just to the rivers direction, the barrel is parallel with the rivers direction this moment, the balance plate plays the stable sample thief effect, the check valve that intakes is opened under the effect of rivers, rivers enter, the rivers that get into the jar body simultaneously flow through a water check valve, treat that the sample thief is after appointed sampling section is stabilized for a few minutes, carry out the water haulage rope rapidly, the barrel is upright this moment, two check valves are closed under hydraulic reaction force, accomplish this moment and cut the sampling through jar body rivers.
The design characteristics are as follows: the gravity center point of the tank body is in the middle position of the tank body, the water inlet hauling rope is fixed on the center points which are perpendicular to the four points and are arranged on the front and back of the tank body and the left and right balance plates of the tank body in an intersecting manner, and the water inlet hauling rope is positioned on the gravity center point of the tank body, so that the tank body is parallel to the horizontal plane when the water inlet hauling rope is held by hands, and water flows into the tank body better during sampling; the water inlet is designed into a conical shape, so that the impact resistance of water flow is reduced, the water flow can more stably pass through the sampler, the flow rate of the water flow entering the tank body is basically equal to the flow rate of the cross section of the simultaneous section, and the accuracy of synchronous sampling is improved; the water inlet check valve at the water inlet is arranged in a built-in manner, and is mainly used for enabling the conical water inlet to have a certain distance to the built-in check valve of the water inlet, so that water flows through the conical water inlet for a certain distance, then the check valve is opened under the action of the water flow, the water flow is prevented from directly acting on the water inlet check valve outside, the water flow is diffused to the periphery under the reaction of the check valve, the water flowing through the section cannot completely enter the tank body, the instantaneous synchronous water sample cannot be accurately reflected, and the water quality stored in the tank body is the instantaneous water quality in the flowing period basically at the moment; the balance plates on the two sides enable the sampler to be more stable in water with flow; when the water flow is too much and the sampler cannot be stabilized in the water body, the stainless steel weight can be additionally arranged to increase the weight of the sampler; the water outlet one-way valve is arranged outside and is used for ensuring that water flowing through the tank body flows out of the tank body more stably; the haulage rope sets up directly the rear at external check valve, and the sample thief is upright under hydraulic reaction when carrying the haulage rope, two check valves close, accomplish to cut the sampling through jar body rivers. The water flow sensor is positioned on the outer side of the tank body, and is used for measuring the flow of water and facilitating later-stage calculation of the discharge amount.
