Specifically, the constant pressure opening device 6 includes a sealing cylinder 601, the sealing cylinder 601 is fixedly connected to the upper side surface of the supporting plate 4, a sealing plate 603 is slidably connected to the inside of the sealing cylinder 601 through a pressure spring 602, the sealing plate 603 slides up and down through the change of water pressure, the pressure spring 602 has certain elasticity to the sealing plate 603, when the sealing plate 603 is not or is subjected to a small amount of water pressure, the pressure spring 602 pushes the sealing plate 603 to be in an upward sliding trend, when the sealing plate 603 is subjected to a large amount of water pressure, that is, when the elasticity of the pressure spring 602 is smaller than the pressure of the water pressure, the sealing plate 603 slides down against the elasticity of the pressure spring 602, the upper side surface of the sealing plate 603 is connected to a U-shaped rod 605 through a screw 604, the U-shaped rod 605 slides along with the sliding of the sealing plate 603, protruding rails 606 are fixedly connected to the side walls at both ends of the lower side of the U-shaped rod, the lower end of the warped rod 608 is movably clamped inside the clamping groove 8, the clamping groove 8 is formed in the side wall of the gland 5, one end of a torsion spring 607 is connected with a rotating shaft of the warped rod 608, the other end of the torsion spring is connected with the side wall of the sleeve 7, the torsion spring 607 applies a certain torsion force to the warped rod 608 to enable the lower end of the warped rod 608 to deflect inwards, the lower end of the warped rod 608 can be stably clamped inside the clamping groove 8, when the clamping groove 8 is clamped with the lower end of the warped rod 608, the gland 5 is in a state of sealing the water intake 301, the gland 5 enables the sampling barrel 3 to be sealed when the device does not reach a preset depth, the upper end of the warped rod 608 is slidably connected to the side wall of the raised rail 606, the gland 5 is connected with the inner side wall of the sleeve 7 through a tension spring 609, when the gland 5 seals the water intake 301, the tension spring 609 has an upward pulling force on the gland 5, and when the device reaches the, the pressure value that receives at intake 301 reaches the preset pressure value of level pressure opening device 6, then closing plate 603 takes U type pole 605 to slide downwards, and protruding rail 606 forces to stick up pole 608 and rotate this moment to stick up the lower extreme of pole 608 and break away from the joint with draw-in groove 8 fast, and extension spring 609 can pull gland 5 and upwards slide this moment, and then intake 301 is opened, and the karst water gets into the inside of sampling bucket 3 this moment.
In order to make the constant pressure opening device 6 work by different water pressure, specifically, a stopper 10 for limiting the upward sliding height of the U-shaped rod 605 is arranged on the side wall of the U-shaped rod 605, the screw 604 is engaged with the U-shaped rod 605 for adjusting the pressure of the sealing plate 603 on the compression spring 602, when the U-shaped rod 605 slides up to the highest position, the stopper 10 abuts against the lower side wall of the support plate 4, at this time, by rotating the screw 604, the position of the U-shaped rod 605 is unchanged and the sealing plate 603 slides in the sealing cylinder 601, the sliding of the sealing plate 603 can adjust the compression amount of the compression spring 602, that is, when the sealing plate 603 slides downwards, the compression amount of the compression spring 602 is increased, that is, the reaction force of the compression spring 602 on the sealing plate 603 is increased, at this time, a greater karst water pressure is required to drive the sealing plate 603 to slide downwards, so that the sealing plate 603 slides, the compression amount of the compression spring 602 is reduced, that is, the reaction force of the compression spring 602 on the sealing plate 603 is relatively small, and at this time, a small karst water pressure is required to drive the sealing plate 603 to slide downwards.
As shown in fig. 4, in order to reduce the sliding friction between the upper end of the tilting rod 608 and the convex rail 606, specifically, the upper end of the tilting rod 608 is rotatably connected with the roller 11, and the roller 11 rolls on the sidewall of the convex rail 606, when the U-shaped rod 605 slides downward, the roller 11 rolls on the sidewall of the convex rail 606, and the tilting rod 608 is rotated by the protrusion of the convex rail 606, so that the lower end of the tilting rod 608 is disengaged from the engaging groove 8.
Particularly, intake 301's shape is the toper, just sampling barrel 3's inside is equipped with the floater 9 that is used for taking full karst water sample back sealed intake 301, and the quality of floater 9 is lighter, and the inside of floater 9 is hollow, therefore floater 9 can float in the karst water, after karst water inflow sampling barrel 3's inside, floater 9 floats along with the karst water, and final intake 301 can be blocked up by floater 9, has realized sampling barrel 3's closure, guarantees that the device rises in-process sampling barrel 3 can not sneak into the upper water.
Particularly, the lower extreme fixedly connected with balancing weight 12 of bottom plate 101, balancing weight 12 can make this device sink in karst aquatic to stable vertical decline in karst aquatic avoids the device to take place the slope.
The working principle is as follows:
the first step is as follows: determining the depth of the taken karst water sample, and calculating the water pressure value at the depth of the karst water sample to be taken, namely calculating by the formula p ═ rhogh (p is the liquid pressure and rho is the liquid density, for example, the density of water is 1 x 10^3kg/m3G is the gravity acceleration of 9.8, h is the height from the pressure point to the liquid level);
the second step is that: the compression amount of the initial compression spring 602 is adjusted through the water pressure value with the designated depth, namely the height of the sealing plate 603 in the sealing cylinder 601 at the initial time is adjusted, and the deeper the sampling depth is, the lower the position of the sealing plate 603 in the sealing cylinder 601 is;
the third step: the sealing plate 603 is adjusted to the proper position by turning the screw 604;
the fourth step: tying the rope 2 to the upper end of the pole 102;
the fifth step: the device is slowly put into the karst water by the traction of the rope 2, when the device reaches the set karst water depth, the water pressure at the water intake 301 does not reach the set pressure value, the constant pressure opening device 6 does not act, and the water intake 301 keeps the state of being sealed by the gland 5; when the device reaches the preset depth of the karst water, the pressure value at the water intake 301 reaches the preset pressure value of the constant pressure opening device 6, the gland 5 opens the water intake 301, and the karst water enters the sampling barrel 3 through the water intake 301;
and a sixth step: after a certain time, the karst water sample is completely collected, the device is pulled out of the water surface, and then the water can be taken out for subsequent treatment by dumping.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
