[0021] Referring to Figures 1-6 , a preferred embodiment provided by the present application is shown.
[0022] The bed sand sampler provided by the present application has better mobility, comprising a sand sampling cylinder 100 in a cylindrical shape, the sand sampling cylinder 100 has a sand sampling cavity 101, the sand sampling cavity 101 penetrates the front end of the sand sampling cylinder 100 to form a sand sampling opening; the sand sampling opening is outwardly inclined to form an outwardly expanding ring 120 arranged in a ring shape; The front part of the sand sampling cylinder 100 forms a front part section, the front part section has a front part cavity, the rear part of the sand sampling cylinder 100 forms a rear part section, the rear part section has a rear part cavity, the front part cavity and the rear part cavity are communicated to form the sand sampling cavity 101, and the sand sampling opening is formed at the end of the front part section; The outer periphery of the front part section is provided with a rotatable connecting ring 200, the connecting ring 200 is arranged along the circumferential direction of the front part section, the connecting ring 200 is provided with a connecting frame 210, the lower end of the connecting frame 210 has two connecting ends, the two connecting ends are rotatably connected to the circumferential side of the connecting ring 200 and are oppositely arranged, the upper end of the connecting frame 210 forms a collection end connected with a rope, when the connecting frame 210 is coaxially arranged with the sand sampling cylinder 100, the collection end is located in front of the sand sampling opening; The outer periphery of the front part section is provided with a rotatable counterweight ring 300, the two sides of the counterweight ring 300 respectively extend outwardly to form a counterweight rod 310 extending in a strip shape, the connecting ring 200 is arranged between the sand sampling opening and the counterweight ring 300; the rear end of the rear part section has a bottom plate arranged away from the sand sampling opening, the middle part of the bottom plate forms a water permeable hole through which a water body passes.
[0023] The provided bed sand sampler with good mobility is connected with the connecting frame 210 through a rope, and the sand collecting barrel 100 is lowered into the water body. Under the weight of the counterweight rods 310, the sand collecting barrel 100 is inverted to be flat, and the counterweight rods 310 abut on the riverbed. Then, the sand collecting barrel 100 is pulled, and the counterweight rods 310 move along the riverbed. Due to the weight of the counterweight rods 310 and the resistance of the riverbed, the sand collecting opening is inserted into the riverbed, so that the sand along the way enters the sand collecting cavity 101 through the sand collecting opening. In addition, the water body quickly enters the sand collecting cavity 101 through the water permeable hole in the bottom during the immersion of the longitudinal sand collecting barrel 100 in the water body, so as to balance the pressure inside and outside the sand collecting barrel 100, and help the sand collecting barrel 100 to stably sink in the water body. At the same time, the water floating above the sand in the sand collecting cavity 101 can be quickly discharged through the water permeable hole. In this way, the operation is simple, the sand sample can be quickly collected, and the applicability is wide.
[0024] Operation method: connect the rope with the connecting frame 210, pull the rope to keep the sand collecting barrel 100 in a longitudinal arrangement state, and then lower the sand collecting barrel 100 into the water body from top to bottom. The water body enters the sand collecting cavity 101 through the water permeable hole until the entire sand collecting barrel 100 is immersed in the water body, and the water body fills the sand collecting cavity 101. Continue to lower the sand collecting barrel 100 in the water body until the bottom plate abuts on the riverbed, and then lower the rope by a set length to make the sand collecting barrel 100 inverted to be flat, and the two counterweight rods 310 abut on the riverbed under the weight of the counterweight rods 310. After keeping the sand collecting barrel 100 in the flat state for a set time, the rope is pulled to move the sand collecting barrel 100, the sand collecting opening is inclined downward and inserted into the riverbed, and then the sand on the riverbed enters the sand collecting cavity 101 through the sand collecting opening. When the sand collecting barrel 100 is moved by a set distance by the rope, the rope is pulled to take out the sand collecting barrel 100 from the water body, and the sand sample collection is completed.
[0025] The outer expansion ring 120 has a plurality of triangular outer convex triangular regions, and the plurality of outer convex triangular regions are sequentially arranged along the circumference of the outer expansion ring 120. Adjacent outer convex triangular regions form an inner concave triangular region. The outer convex triangular region includes two inclined plates 121, the outer ends of the two inclined plates 121 are butted to form a butted end arranged in a strip shape, and the inner ends of the two inclined plates 121 are arranged apart. A separation interval is formed between the inner ends of the two inclined plates 121, and the separation interval and the butted end enclose the outer convex triangular region. The inner ends of the inclined plates 121 of adjacent outer convex triangular regions are butted and connected, and the plurality of outer convex triangular regions are sequentially connected in order. In this way, the triangular outer convex triangular region formed by the butting of the two inclined plates 121 makes the outer expansion ring 120 more easily inserted into the riverbed, and the outer expansion ring 120 is inserted into the soil under the action of the gravity of the counterweight rods 310.
[0026] The abutting end is arranged in a pointed end, and the abutting end is arranged inwardly inclined along the axis of the sand collecting cavity 101. In this way, the pointed end reduces the contact area and increases the acting force.
[0027] The end of the front section is arranged outwardly inclined, forming an inclined ring 110, which surrounds the sand collecting opening, and the outer expansion ring 120 is rotationally sleeved on the outer periphery of the inclined ring 110; along the circumference of the outer expansion ring 120, the included angles of adjacent outer convex triangular regions are different. In this way, when the direction of the rope pulling the sand collecting barrel 100 changes, the outer expansion ring 120 rotates relative to the inclined ring 110, allowing the sand collecting barrel 100 to move smoothly.
[0028] The outer periphery of the inclined ring 110 extends outwardly with an inner expansion ring 400, which is arranged around the outer expansion ring along the circumferential direction; the inner end of the inner expansion ring 400 is connected integrally with the inner end of the outer expansion ring 120, and the outer end of the inner expansion ring 400 is arranged outwardly inclined from the outer end of the outer expansion ring 120, and the inner expansion ring 400 and the outer expansion ring 120 form an annular sieve leakage area 401 therebetween, and the inner expansion ring 400 is provided with a plurality of sieve leakage holes 402, and the sieve leakage area 401 communicates with the front cavity through the sieve leakage holes 402.
[0029] In this way, when the sand is mixed with some bulk impurities during the process of entering the front cavity, the inner expansion ring 400 can be used to block the impurities from entering the front cavity, and the sand entering the sand leakage area 401 can pass through the sieve leakage holes 402 to enter the front cavity, so that the sand entering the front cavity can be screened.
[0030] The middle part of the bottom plate is recessed towards the sand collecting cavity 101, forming a conical wall in the shape of a conical cylinder, which surrounds the outer concave cavity 102 with an open bottom; the top of the conical wall forms an inner convex position in the sand collecting cavity 101, and the water permeable hole is formed on the inner convex position. In this way, the sand in the sand collecting cavity 101 can be prevented from leaking out through the water permeable hole. At the same time, after the sand collecting barrel 100 is taken out from the water body, the water floating on the sand can quickly flow out.
[0031] The conical wall extends through the rear cavity to the middle part of the front cavity. In this way, the space for sand accumulation is increased.
[0032] Specifically, the inner convex position is an inner convex plate 1000 in the shape of a flat plate, and the inner convex plate 1000 is provided with a plurality of water permeable holes arranged in a spaced annular manner.

In this way, the space is increased, the diameter of the profile of the rear section of the sand collecting barrel 100 is increased, the whole is large at the rear and small at the front, when the counterweight rod 310 abuts against the riverbed, the axis of the sand collecting barrel 100 is in an inclined state, the strength of the outer cavity 102 is enhanced through the design of the mesh layer 130, and large foreign matters are avoided from being located in the outer cavity 102.
[0034] The counterweight ring 300 extends outward at both sides and has a connecting shaft, the inner end of the counterweight rod 310 has a shaft hole 301, the connecting shaft is rotatably inserted into the shaft hole 301, the outer end of the counterweight rod 310 extends outward away from the counterweight ring 300, and the counterweight rod 310 is arranged in a flat shape. In this way, through the design of the connecting shaft and the shaft hole 301, the counterweight rod 310 can be quickly installed on the counterweight ring 300, and the counterweight rod 310 can rotate, reducing the water flow resistance in the horizontal movement process.
[0035] The side surface of the counterweight rod 310 is curved. In this way, the edges and corners are avoided to limit the laying down of the sand collecting barrel 100.
[0036] A plurality of through holes 311 are arranged in the counterweight rod 310, the plurality of through holes 311 penetrate the counterweight rod 310 along the thickness direction of the counterweight rod 310, and the plurality of through holes 311 are arranged at intervals along the length direction of the counterweight rod 310.
