A number of water inlet holes 6 are provided on the side of the casing pipe 5, and the water inlet holes 6 form a circle along its circumference. The top is inclined to the left, and the inclination angle of the water inlet hole 6 is the same as that of the water guide hole 2. This arrangement makes it possible for the inner cavity of the water inlet hole 6 to communicate with the water guide hole 2 after it moves to the right for a certain distance, forming a A relatively complete and straight channel is convenient for water to enter. Secondly, the upper water inlet of the water inlet 6 is always exposed. The water inlet 6 is inclined along the direction of the water flow, so that impurities in the water flow can pass through more easily. The area around the water inlet hole 6 can prevent impurities from accumulating in the water inlet hole 6. The water inlet hole 6 and the communication groove 9 are all located on the left side of the water guide hole 2, and the water outlet at the lower end of the water inlet hole 6 is connected to the upper end of the water guide hole 2. The distance between the water outlets is equal to the distance between the water inlet at the upper end of the communication groove 9 and the water outlet at the lower end of the water guide hole 2. After the casing 5 and the piston block 8 move to the right for a certain distance, the water inlet 6 and the water guide hole 2 A complete water flow channel is formed with the inner cavity of the communication groove 9 for water flow into the cylinder body 1;
取水管7的右端穿设在迎水体3的中部，与迎水体3内腔连通，当取水管7开始抽取水质样品时，迎水体3内部会形成负压，可使得水流经过通孔4进入其内部并被取样管抽走检测，具体的，在实际应用过程中，进水管的另一端需要连接泵，用于为水质样品的抽离提供动力；The right end of the water intake pipe 7 is installed in the middle of the water intake body 3, and communicates with the inner cavity of the water intake body 3. When the water intake pipe 7 starts to take water quality samples, a negative pressure will be formed inside the water intake body 3, allowing water to flow through the through hole 4 into its The inside is pumped away by the sampling tube for detection. Specifically, in actual application, the other end of the water inlet tube needs to be connected to a pump to provide power for the extraction of water quality samples;
活塞块8活动套设在取水管7的外侧，可在取水管7的外侧来回滑动，其外侧壁与缸体1内壁接触，并能够将缸体1内腔的左右两侧进行隔绝，当迎水体3内形成负压时，负压传递到缸体1内部会带动活塞移动，活塞块8与迎水体3之间具有间隙，为水流经过时提供空间，活塞块8的内部开设有连通槽9，优选的，连通槽9由竖直段与倾斜端组成，其倾斜端的底部出口与间隙的内腔连通，且连通槽9、进水孔6与导水孔2之间一一对应；The piston block 8 is movably sleeved on the outside of the water intake pipe 7, and can slide back and forth on the outside of the water intake pipe 7. Its outer wall contacts the inner wall of the cylinder body 1, and can isolate the left and right sides of the cylinder body 1 inner cavity. When negative pressure is formed in the water body 3, the negative pressure transmitted to the inside of the cylinder body 1 will drive the piston to move. There is a gap between the piston block 8 and the water body 3 to provide space for the water flow to pass. The piston block 8 is provided with a communication groove 9 , preferably, the communication groove 9 is composed of a vertical section and an inclined end, and the bottom outlet of the inclined end communicates with the inner cavity of the gap, and there is a one-to-one correspondence between the communication groove 9, the water inlet hole 6 and the water guide hole 2;
受力板10与活塞块8一体式的套设在取水管7的外侧，其右端面固定设置在套管5的左端面上，具体的，受力板10可与活塞块8之间固定连接，然后整体套设在取水管7的外侧，受力板10的尺寸大于套管5的尺寸，该种设置方式，使得当迎水体3内没有负压时，受力板10受到水流的冲击作用，会带动活塞块8和套管5移动，可将水流通道封闭，套管5与缸体1之间的距离等于进水孔6下端出水口与导水孔2上端进水口之间的距离，该种设置方式，使得进水孔6、导水孔2和连通槽9之间形成完整的水流通道的同时，受力板10的右端面与缸体1接触并无法继续移动，此时，为进水孔6与连通槽9进行位置固定，保障水流通道的有效疏通性；The force plate 10 and the piston block 8 are integrally set on the outside of the water intake pipe 7, and its right end surface is fixedly arranged on the left end surface of the casing 5. Specifically, the force plate 10 can be fixedly connected to the piston block 8 , and then the whole is set on the outside of the water intake pipe 7, the size of the force plate 10 is larger than the size of the casing 5, this kind of arrangement makes when there is no negative pressure in the water-facing body 3, the force plate 10 is impacted by the water flow , will drive the piston block 8 and the casing 5 to move, and the water flow channel can be closed, and the distance between the casing 5 and the cylinder body 1 is equal to the distance between the water outlet at the lower end of the water inlet hole 6 and the water inlet at the upper end of the water guide hole 2, This arrangement makes the water inlet hole 6, the water guide hole 2 and the communication groove 9 form a complete water flow channel, and at the same time, the right end surface of the force plate 10 is in contact with the cylinder body 1 and cannot continue to move. The position of the water inlet hole 6 and the communication groove 9 is fixed to ensure the effective dredging of the water flow channel;
在取样过程中，套管5以及迎水体3内形成负压，活塞块8受到负压在取水管7的外侧向右侧移动，与此同时，套管5跟随取水管7同步移动，此时，进水孔6与连通槽9分别向导水孔2的上端进水口与其下端出水口运动，当进水孔6、导水孔2与连通槽9的内腔连通时，形成一个水流通道，水质样品通过该通道进入间隙内并最终由通孔4被取样管抽走检测，而在非工作状态时，负压小时，受力板10在水流冲击作用下带动活塞板和套管5恢复到初始位置，此时，水流通道被封闭，杂质无法进入到间隙内部，从而保障间隙内腔清洁无杂质，可有效防止取水管7堵塞During the sampling process, a negative pressure is formed in the sleeve pipe 5 and the water-facing body 3, and the piston block 8 moves to the right outside the water intake pipe 7 under the negative pressure. At the same time, the sleeve pipe 5 moves synchronously with the water intake pipe 7. At this time , the water inlet 6 and the communication groove 9 move respectively to the upper water inlet of the water guide hole 2 and the lower end water outlet, when the water inlet 6, the water guide hole 2 communicate with the inner cavity of the communication groove 9, a water flow channel is formed, and the water quality The sample enters the gap through the channel and is finally taken away by the sampling tube through the through hole 4 for detection. In the non-working state, the negative pressure is small, and the force plate 10 drives the piston plate and the casing 5 to return to the original state under the impact of the water flow. At this time, the water flow channel is closed, and impurities cannot enter the gap, so as to ensure that the inner cavity of the gap is clean and free of impurities, which can effectively prevent the water intake pipe 7 from being blocked
当然，为了更好的防止杂质进入进水孔6内，迎水体3的外侧面还可以向外具有凸起，凸起的左端面固定设置有挡板11，挡板11的内径与缸体1的外径差等于套管5的厚度，且挡板11内壁的左端具有倒角，该种设置方式，使得当水流通道形成之后，进水孔6正好位于倒角的下方，此时，挡板11的外侧壁可将杂质进行一定的隔绝并对向进水孔6一侧移动的杂质进行导流，让杂质顺着水流继续流动，并增加杂质进入进水孔6的难度，从而降低杂质进入缸体1的概率，起到防堵塞的效果。Of course, in order to better prevent impurities from entering the water inlet 6, the outer surface of the water-receiving body 3 can also have a protrusion outward, and the left end surface of the protrusion is fixedly provided with a baffle 11, and the inner diameter of the baffle 11 is the same as that of the cylinder body 1. The outer diameter difference is equal to the thickness of the casing 5, and the left end of the inner wall of the baffle 11 has a chamfer. This arrangement makes the water inlet 6 just below the chamfer after the water flow channel is formed. At this time, the baffle The outer wall of 11 can isolate the impurities to a certain extent and guide the impurities moving to the side of the water inlet 6, so that the impurities continue to flow along the water flow, and increase the difficulty of impurities entering the water inlet 6, thereby reducing the impurities entering The probability of cylinder 1 plays an anti-clogging effect.
