Example (b):

referring to fig. 1 and 2, an embodiment of the present invention discloses an underground water sampler, which includes a base 110, a first bobbin 113, a second bobbin 114, a water sampler 120, and a blocking assembly 130. The base 110 is used for being installed on the ground, the first winding frame 113 and the second winding frame 114 are both installed on the base 110, the first winding frame 113 is provided with a first connecting rope 111 connected with the water sampler 120, and the second winding frame 114 is provided with a second connecting rope 112 connected with the water sampler 120. The water sampler 120 is provided with a first opening 124 for water inflow and a water outlet 125 for water drainage, the plugging component 130 is connected with the second connecting rope 112, and the plugging component 130 is used for plugging the first opening 124 and the water outlet 125. When the water sampler 120 is pulled by the first connecting rope 111, the first opening 124 and the water outlet 125 are both in an open state, and at this time, the water sampler 120 can be thrown towards the ground; when the water sampler 120 is pulled by the second connection string 112, the first opening 124 and the water outlet 125 are closed, and thus, are used to collect groundwater.

The groundwater sampler disclosed in this embodiment controls the lowering of the sampler 120 by using the first connecting rope 111, and since the first opening 124 and the water outlet 125 are both open, the sampler 120 can be lowered smoothly without accumulating groundwater in the top layer in the sampler 120. The scales can be arranged on the first connecting rope 111, when the water sampler 120 descends to a designated height, the second connecting rope 112 is pulled, the first opening 124 and the water outlet 125 of the water sampler 120 are both closed, the water in the water sampler 120 is the groundwater with the designated height, and then the groundwater with the designated underground depth can be obtained by pulling up the water sampler 120 through the second connecting rope 112. Simple structure, it is convenient to gather, can be fast and accurate gather the groundwater of assigned position, and it is convenient for subsequent research physique.

The base 110 is installed on the surface of the earth and is disposed above a groundwater wellhead. The first bobbin 113 and the second bobbin 114 are both installed on the base 110, and the first bobbin 113 and the second bobbin 114 are spaced apart in the horizontal direction to prevent the first connection string 111 and the second connection string 112 from being wound when the water sampler 120 descends or ascends.

Referring to fig. 4-4, the water sampler 120 includes a top wall 123, a bottom wall 121, and a perimeter wall 122. The peripheral wall 122 is annular around the circumference of the bottom wall 121, the top wall 123 is mounted at one end of the peripheral wall 122 facing away from the bottom wall 121, and the bottom wall 121, the peripheral wall 122 and the top wall 123 together enclose a water collecting cavity for storing water. The bottom wall 121 is provided with a first opening 124, the joint of the peripheral wall 122 and the bottom wall 121 is provided with a water outlet 125, the top wall 123 is provided with a second opening 127, and the arrangement of the second opening 127 enables the groundwater to penetrate through the hydrophone 120 more quickly when the hydrophone 120 descends, so that the groundwater on the surface layer is prevented from staying in the hydrophone 120, and the groundwater collected in the hydrophone 120 is guaranteed to be the groundwater with the designated depth.

The top wall 123 is provided with a flip cover 126, the flip cover 126 is used for controlling the opening and closing of the second opening 127, when the second opening 127 is opened, water in the water sampler 120 can smoothly leave through the second opening 127, and when the second opening 127 is closed, groundwater spilling caused by shaking when the water sampler 120 is lifted can be avoided. Specifically, the flip cover 126 is rotatably connected with the top wall 123, the rotation axis of the flip cover 126 is parallel to the top wall 123, and the maximum opening angle of the flip cover 126 is smaller than or equal to 45 degrees, so that when the water sampler 120 ascends, the second switch can be quickly closed by using water resistance, and therefore, the groundwater on the surface layer is prevented from entering the water sampler 120 when the water sampler 120 ascends.

Referring to fig. 2, the blocking assembly 130 is used to control the opening and closing of the first opening 124 and the water outlet 125, so as to facilitate the descent of the water sampler 120 or the water sampling. The blocking assembly 130 includes a blocking piece 131, a water deflector 132, an elastic member 134, a third connecting string 133, a balancing plate 135 and a control structure 136.

One end of the first connection rope 111 is wound on the first winding frame 113, and the second end of the first connection rope 111 is fixedly connected with the top wall 123 of the water sampler 120, so that the water sampler 120 can be easily driven to ascend or descend when the first winding frame 113 rotates.

One end of the second connecting rope 112 is wound on the second winding frame 114, the other end of the second connecting rope 112 penetrates through the top wall 123 of the water sampler 120 and then extends into the water sampling cavity, and then extends out of the water outlet 125 on the side wall of the water sampler 120, and the blocking piece 131 is connected to one end of the second connecting rope 112 extending out of the water outlet 125, namely the blocking piece 131 is located outside the water sampler 120. One end of the third connecting rope 133 is connected with one end of the blocking piece 131 departing from the second connecting rope 112, and the other end of the third connecting rope 133 is connected with one end of the water baffle 132 facing the first opening 124. An elastic member 134 is disposed between the water deflector 132 and the bottom wall 121, and the elastic member 134 makes the water deflector 132 have a tendency to move away from the bottom wall 121, when the water deflector 132 moves away from the bottom wall 121, the first opening 124 is opened, and when the water deflector 132 moves close to the bottom wall 121, the first opening 124 is closed.

In use, when no external force is applied to the second connecting string 112, the water deflector 132 is moved away from the bottom wall 121 by the elastic member 134, and the first opening 124 is opened. Meanwhile, the water blocking plate 132 pulls the blocking piece 131 through the third connecting rope 133, so that the blocking piece 131 is away from the range of the water outlet 125, and the water outlet 125 is also in an open state. At this time, the water sampler 120 can be smoothly lowered without worrying about the surface layer of groundwater remaining in the water sampler 120. When the second connection rope 112 is pulled by the second bobbin 114, the second connection rope 112 pulls the blocking piece 131 to approach towards the water outlet 125 and block the water outlet 125, and meanwhile, the blocking piece 131 pulls the water baffle 132 to approach towards the bottom wall 121 and block the first opening 124 by the third connection rope 133 against the elastic force of the elastic piece 134, namely, when the blocking piece 131 blocks the water outlet 125, the length of the third connection rope 133 enables the water baffle 132 to just block the first opening 124. The second connecting rope 112 is pulled at this time, the water sampler 120 can be taken out, and the groundwater in the water sampler 120 is the groundwater in the designated position at this time.

In this embodiment, the cross section of the water outlet 125 is made to be circular, and the cross section of the block 131 is gradually reduced along the direction toward the second connecting rope 112, and the minimum diameter of the block 131 is smaller than the diameter of the water outlet 125, and the maximum diameter of the block 131 is larger than the diameter of the water outlet 125. This further facilitates the closure of the outlet 125. A spring may be further provided between the block 131 and the second connection string 112, and the spring may increase an acting force between the block 131 and the sidewall of the water sampler 120, thereby improving sealability.

In order to avoid violent shaking of the water sampler 120 when the second connecting rope 112 is pulled, a balance plate 135 may be disposed on the second connecting rope 112, and the balance plate 135 is mainly used to balance the acting force of the second connecting rope 112 on the water sampler 120. Specifically, the balance plate 135 is fixed in the second connecting rope 112, and the balance plate 135 is located in the water sampling cavity, and when the second connecting rope 112 is pulled, the balance plate 135 is abutted to the top wall 123 of the water sampler 120, so that the stress of the water sampler 120 is more balanced, and the water sampler 120 is more stable when ascending. It should be noted that, in order to ensure that the water outlet 125 and the first opening 124 can be stably closed when the second connecting rope 112 is pulled, the installation position of the balancing plate 135 needs to be controlled, that is, when the balancing plate 135 needs to be in contact with the top wall 123, the blocking piece 131 at the end of the second connecting rope 112 also just closes the water outlet 125, so as to ensure that water leakage does not occur when the water sampler 120 is lifted.

When the second connection string 112 is released after the water sampler 120 is lifted, the first opening 124 and the water outlet 125 are opened immediately, and water in the water sampler 120 is directly leaked out, so that the plugging assembly 130 disclosed in this embodiment further includes a control structure 136 for limiting the balance plate 135 in order to collect groundwater in the water sampler 120.

Specifically, referring to fig. 6, control structure 136 includes a first connecting bar 1362, a control bar 1361, a restrictor plate 1364, and a restrictor plate 1363. The first connecting rod 1362 is rotatably connected with the top wall 123 of the water sampler 120, one end of the first connecting rod 1362 extends into the water sampling cavity, and the other end of the first connecting rod 1362 is left outside the water sampler 120. The control rod 1361 is connected to one end of the first connecting rod 1362, which is left outside the water sampler 120, and the first connecting rod 1362 can be driven to rotate by the control rod 1361. The limiting plate 1364 and the limiting plate 1363 are connected with one end of the first connecting rod 1362 extending into the water production cavity, the limiting plate 1364 is connected with one end of the first connecting rod 1362 away from the control rod 1361, the limiting plate 1363 is located between the limiting plate 1364 and the control rod 1361, one end of the limiting plate 1363 is connected with the limiting plate 1364, the other end of the limiting plate 1363 is arranged at an interval with the top wall 123, and the distance between the limiting plate 1363 and the top wall 123 is equal to the thickness of the balance plate 135.

Referring to fig. 6 and 7, through hole 1351 for matching with limiting plate 1363 is provided on balance board 135, through hole 1351 is slidably matched with limiting plate 1363, and by rotating first connecting rod 1362, whether limiting plate 1363 is aligned with through hole 1351 or not can be controlled, and when limiting plate 1363 is aligned with through hole 1351, balance board 135 can move towards limiting plate 1364, that is, balance board 135 can move away from top wall 123; after the balance plate 135 is attached to the top wall 123, the first connecting rod 1362 can drive the limiting plate 1363 to rotate to be staggered with the through hole 1351, and at this time, the balance plate 135 is limited to be attached to the top wall 123. Wherein the cross-section of restrictor plate 1364 is larger than the cross-section of restrictor plate 1363 to avoid the balance plate 135 from moving out of the range of control structure 136.

In this embodiment, the control structure 136 is further capable of restricting the water deflector 132 such that in a certain state, the control structure 136 releases the restriction of the balancing plate 135 and simultaneously restricts the water deflector 132, so that the water sampler 120 is taken out and then only opens the water outlet 125 without opening the first opening 124, thereby facilitating the collection of groundwater in the water sampler 120.

Specifically, control structure 136 also includes a second connecting rod 1365 and a stop bar 1366. The second connecting rod 1365 is connected with one end of the limiting plate 1364, which is away from the first connecting rod 1362, the second connecting rod 1365 and the first connecting rod 1362 are coaxially arranged, and the second connecting rod 1365 and the water baffle 132 are arranged in a staggered manner along the height direction of the water sampler 120. The stop bar 1366 is connected to the second connecting rod 1365, and the stop bar 1366 is mounted on a side wall of the second connecting rod 1365, so that the stop bar 1366 extends out of the second connecting rod 1365 along only one side of the second connecting rod 1365, and a projection of the stop bar 1366 in the height direction of the water sampler 120 is located in a projection of the limiting plate 1363 in the height direction of the water sampler 120. The first connecting rod 1362 is rotated to intersect or stagger the projections of the stop 1366 and the breakwater 132 in the height direction of the water sampler 120, and the stop 1366 can come into abutment with the breakwater 132 when the breakwater 132 is caught in the first opening 124.

In this embodiment, the second connecting rod 1365 is tangent to the splash plate 132. On one hand, the sliding of the splash guard 132 is more stable, and on the other hand, the rotation of the second connecting rod 1365 is ensured to be more stable, so that the baffle 1366 can be ensured to smoothly limit the splash guard 132.

The second connecting rope 112 may include two sections, the first section is wound around the second winding frame 114, the second section penetrates into the water sampling cavity, and the second end of the second section is partially left outside the water sampler 120, and the position and the first end may be detachably connected in a manner of hook, etc., so that the water sampler 120 is conveniently taken down from the base 110 after the water sampler 120 is lifted.

The control structure 136 is specifically used as follows: when the water sampler 120 needs to be lowered for water sampling, the control lever 1361 is rotated to make the limiting plate 1363 opposite to the through hole 1351, and the stop lever 1366 is rotated to the side away from the water baffle 132. At this time, the water deflector 132 is moved away from the first opening 124 by the elastic member 134, and pulls the block 131 to open the water outlet 125, and the block 131 pulls the balance plate 135 to move along the limiting plate 1363 toward the limiting plate 1364.

When the groundwater needs to be collected after the water sampler 120 is lowered to a designated position, the second connecting rope 112 is pulled, at which time the balance plate 135 is first moved to be adhered to the ceiling wall 123, the block 131 is moved to close the water outlet 125, and the water baffle 132 is moved to close the first opening 124.

When the water sampler 120 comes from life, the control rod 1361 is rotated first, the control rod 1361 is rotated by an angle in the first direction, the angle is larger than 0 degree and smaller than 180 degrees, the limiting plate 1363 is staggered with the through hole 1351 on the balance plate 135, the control structure 136 limits the balance plate 135, the balance plate 135 cannot move, the blocking block 131 and the water baffle 132 cannot move, and the water sampler 120 can be moved randomly without worrying about the leakage of groundwater.

After the water sampler 120 is moved to the upper part of the designated container, the control rod 1361 continues to rotate in the first direction, so that the sum of the first rotation angle and the second rotation angle of the control rod 1361 is equal to 180 degrees (in the process, for convenience of control, the control rod 1361 may be rotated 90 degrees each time, and of course, a scale or a block may be provided on the top wall 123 of the water sampler 120 for convenience of operation). At this time, the limiting plate 1363 is aligned with the through hole 1351 again, but the stop bar 1366 is rotated to abut against the water baffle 132, i.e. although the balance plate 135 can be moved freely, the water baffle 132 cannot be far away from the bottom wall 121 of the water sampler 120, i.e. the first opening 124 of the bottom wall 121 is continuously in a closed state. The block 131 leaves the water outlet 125 under the pressure of the groundwater in the water sampler 120, so that the groundwater in the water sampler 120 can smoothly flow into a designated container through the water outlet 125 without worrying about the groundwater leaking from the first opening 124 on the bottom wall 121 of the water sampler 120.

When the groundwater in the water sampler 120 is discharged, the second connecting rope 112 is pulled again, so that the balance plate 135 is attached to the top wall 123 of the water sampler 120 again. After the control rod 1361 is turned 180 degrees in a second direction opposite to the first direction, the restriction of the balance plate 135 and the water guard plate 132 is released again, and the groundwater collection can be performed again by the water sampler 120.

In the present embodiment, the clockwise direction in fig. 6 is taken as the first direction, and the counterclockwise direction in fig. 6 is taken as the second direction.

It should be noted that the above control structure 136 is only one embodiment of the present embodiment, and in the structural design for limiting the water deflector 132, the control structure 136 may be designed to be provided with only one second connecting rod 1365 additionally arranged at the bottom of the limit plate 1364. Referring to fig. 7 and 8, the second connecting rod 1365 and one end of the limit plate 1364 away from the first connecting rod 1362 are connected, the second connecting rod 1365 and the limit plate 1364 are eccentrically arranged, a projection of the second connecting rod 1365 in the height direction of the water sampler 120 is located in a projection of the limit plate 1363 in the height direction of the water sampler 120, the first connecting rod 1362 is rotated to intersect or stagger the projections of the second connecting rod 1365 and the splash plate 132 in the height direction of the water sampler 120, and when the splash plate 132 is clamped into the first opening 124, the second connecting rod 1365 can abut against the splash plate 132. The operation mode is the same as the operation mode of the control structure 136, that is, when the control rod 1361 is rotated by a certain angle along the first direction, the balance plate 135, the blocking piece 131 and the water baffle 132 can be limited; after the control rod 1361 rotates enough in the first direction for 180 degrees, the balance plate 135 and the stopper are released from the limit, but the water guard 132 is still limited; when the control lever 1361 is rotated 180 degrees in the second direction, the restriction of the balance plate 135, the jam 131 and the splash plate 132 is released again.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
