[0001] The utility model relates to the technical field of hydrogeological exploration, in particular to a water sample collection device for hydrogeological exploration. Background Technique

[0002] Geological exploration refers to the investigation and research work with different focuses on the geological conditions such as rocks, stratigraphic structures, minerals, groundwater, landforms, etc. in a certain area through various means and methods. Among them, hydrogeological exploration is an important branch of geological exploration, mainly studying the distribution and formation law of groundwater, the physical properties and chemical components of groundwater, groundwater resources and their rational utilization, the adverse effects of groundwater on engineering construction and mine exploitation and their prevention and control, etc.

[0003] Most of the existing sampling devices use sampling water buckets to sample samples. Its advantages are simple structure, low weight and cost, and convenient to carry. However, after the existing sampling water bucket descends to the water surface, due to its own shape problem, it is necessary to manually assist in shaking the sampling water bucket to pour it, so that the sampling water bucket can sample. When using this method, the operation of pouring the sampling water bucket is difficult, and it wastes a lot of time and labor, resulting in extremely low sampling efficiency. Content of the Utility Model

[0004] To solve the problems raised in the above background technique. The utility model provides a water sample collection device for hydrogeological exploration.

[0005] To achieve the above object, the technical solution of the utility model is that a water sample collection device for hydrogeological exploration includes a sampling water bucket.

A rope winding wheel is installed on the valve shaft of the sampling valve. An adjusting rope is wound and installed on the rope winding wheel. One side of the center inside the sampling water bucket is provided with an adjusting pipe. The lower end of the adjusting pipe is communicated with the bottom of the sampling water bucket, and the adjusting rope is movably inserted into the adjusting pipe. Ring-shaped baffles are arranged at the upper and lower ends of the outer surface of the sampling water bucket. A plurality of concave slide rails are arranged between the two ring-shaped baffles and are evenly distributed on the outer surface of the sampling water bucket and are connected with the sampling water bucket.

[0006] As a water sample collection device for hydrogeological exploration of the utility model, a plurality of legs are installed at the bottom of the sampling bucket and are evenly distributed outside the bottom of the sampling bucket, and the length of the legs is greater than the length of the sampling tube.

[0007] As a water sample collection device for hydrogeological exploration of the utility model, the legs are made of solid material to increase the overall weight of the sampling bucket.

[0008] As a water sample collection device for hydrogeological exploration of the utility model, the sampling valve is in a normally open state, and as the regulating rope seat drags the regulating rope upward, the sampling valve is gradually closed.

[0009] As a water sample collection device for hydrogeological exploration of the utility model, the rotation resistance of the sampling valve is smaller than the buoyancy of the floating swimming ring and smaller than the gravity of the sampling bucket.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] The present invention provides a technical solution, as Figure 1 - Figure 2 shown; A water sample collection device for hydrogeological exploration, including a sampling bucket 1, a sampling tube 11 is installed at the center of the lower surface of the sampling bucket 1, a sampling valve 12 is installed on the sampling tube 11, a rope winding wheel 121 is installed on the valve shaft of the sampling valve 12, an adjusting rope 122 is wound and installed on the rope winding wheel 121, an adjusting tube 13 is installed on one side of the center inside the sampling bucket 1, the lower end of the adjusting tube 13 is communicated with the bottom of the sampling bucket 1, and the adjusting rope 122 is movably inserted into the adjusting tube 13.

[0022] In the embodiment of the present invention, by using the sampling tube 11 provided at the lower end of the sampling bucket 1 and the sampling valve 12 provided thereon, and the sampling valve 12 being in an open state all the time, after the sampling bucket 1 descends to the water surface, the sample can be quickly injected into the sampling bucket 1 through the sampling tube 11, so that it is not necessary for the staff to manually shake the sampling bucket, making the sampling more convenient, and at the same time ensuring the safety of sampling and improving the sampling efficiency.

[0023] In the embodiment of the present invention, by using the rope winding wheel 121 and the adjusting rope 122 provided on the sampling valve 12, and the adjusting rope 122 passing through the adjusting tube 13 and being located above the sampling bucket 1, it can be made to gradually sink into the water area during the sampling process through the sampling bucket 1, so that the floating swimming ring 221 adjusts the movement of the adjusting rope 122 by its own buoyancy, and the rope winding wheel 121 drives the valve shaft of the sampling valve 12 to rotate, so that the sampling valve 12 is gradually closed. On the one hand, the sampling work can be stopped to avoid the slow rise of the sampling bucket 1 due to excessive sampling volume, and on the other hand, a large amount of sample leakage can be avoided, so as to ensure the sufficient amount of sample collected inside the sampling bucket 1.

[0024] Ring-shaped baffles 2 are provided at the upper and lower ends of the outer surface of the sampling water bucket 1. A number of concave slide rails 21 are provided between the two ring-shaped baffles 2, and are evenly distributed on the outer surface of the sampling water bucket 1 and are connected to the sampling water bucket 1. A sliding seat 211 is slidably installed inside the concave slide rail 21. A ring-shaped mounting plate 22 is provided outside the sampling water bucket 1. The ring-shaped mounting plate 22 is fixedly connected to the sliding seat 211. A floating swimming ring 221 is installed on the outer side of the lower surface of the ring-shaped mounting plate 22. An adjusting rope seat 222 is provided above the sampling water bucket 1. The adjusting rope seat 222 is located above the adjusting pipe 13 and is fixedly connected to the adjusting rope 122. A number of L-shaped support rods 223 are installed on the ring-shaped mounting plate 22. The L-shaped support rods 223 are evenly distributed and are connected to the adjusting rope seat 222.

[0025] In the embodiment of the present utility model, through the arrangement of the concave slide rail 21 and the sliding seat 211, the ring-shaped mounting plate 22 can slide quickly on the outer surface of the sampling water bucket 1. And through the arrangement of the floating swimming ring 221 installed below the ring-shaped mounting plate 22, during the sampling process, as the sampling amount of the sampling water bucket 1 gradually increases, the sampling water bucket 1 gradually sinks into the water, while the floating swimming ring 221 uses its own buoyancy to keep its position unchanged, so that the adjusting rope seat 222 can drag the adjusting rope 122 to gradually extend and drive the sampling valve 12 to close, controlling the stop of the sampling work, and at the same time avoiding a large amount of leakage of the sample.

[0026] In the embodiment of the present utility model, the floating swimming ring 221 is a common solid life buoy, which can ensure the service life of the device and at the same time generate sufficient buoyancy.

[0027] In the embodiment of the present utility model, by using the connection of the L-shaped support rods 223, the ring-shaped mounting plate 22 can remain unchanged with the floating swimming ring 221, so that the adjusting rope seat 222 can use sufficient buoyancy to drag the adjusting rope 122 to extend and drive the sampling valve 12 to close.

[0028] In the present utility model, a number of legs 14 are installed at the bottom of the sampling water bucket 1 and are evenly distributed on the outer side of the bottom of the sampling water bucket 1, and the length of the legs 14 is greater than the length of the sampling pipe 11; by using the arrangement of the legs 14, the sampling water bucket 1 can be stably placed on the ground, which is convenient for the use of the staff and the storage of the sampling water bucket 1.

[0029] In the present utility model, the legs 14 are made of solid material to increase the overall weight of the sampling water bucket 1; by using the solid legs 14, the weight of the sampling water bucket 1 can be increased, so that after it sinks to the water surface, it can quickly sink by its own weight to improve the sampling efficiency.

[0030] In the present utility model, the sampling valve 12 is in a normally open state. As the adjusting rope seat 222 drags the adjusting rope 122 to rise, the sampling valve 12 gradually closes, ensuring the normal operation of the sampling work and using the closing of the sampling valve 12 to control the stop of the sampling work.

[0031] In the present utility model, the rotational resistance of the sampling valve 12 is less than the buoyancy of the floating swimming ring 221 and less than the gravity of the sampling bucket 1, enabling the sampling valve 12 to be quickly closed by adjusting the adjusting rope 122.

[0032] In the present utility model, the sampling volume of the sampling bucket 1 is half of the volume of the sampling bucket 1, reducing the overall weight of the device after sampling and avoiding the problem of excessive weight of the device caused by excessive sample collection.

[0033] In the present utility model, a cross bracket 15 is installed above the inside of the sampling bucket 1, a suspension rod 151 is installed above the center of the cross bracket 15, and a hanging ring 152 is installed at the upper end of the suspension rod 151, facilitating the connection of the sampling bucket 1 with the hoisting equipment and making it more convenient for the staff to use.

[0034] When specifically using the present utility model, the staff takes out the sampling bucket 1 and connects the hanging ring 152 with the hoisting equipment. Subsequently, the staff manually rotates the sampling valve 12 to detect whether it is in a fully open state. When the sampling valve 12 is fully open, as the hoisting equipment operates, the sampling bucket 1 gradually descends.

[0035] When the sampling bucket 1 descends to the water surface, at this time, the sampling bucket 1 contacts the water surface, and at the same time, the floating swimming ring 221 also contacts the water surface and floats above the water surface. The sampling bucket 1 gradually sinks below the water surface by its own weight. Through the sliding fit of the concave slide rail 21 and the sliding seat 211, it can be ensured that the sampling bucket 1 smoothly sinks below the water surface.

[0036] As the sampling bucket 1 sinks below the water surface, the sample is gradually injected into the sampling bucket 1 through the sampling pipe 11, and the sampling work of the water area begins. At the same time, as the sampling bucket 1 sinks, the floating swimming ring 221 rises in height relative to the sampling bucket 1. Then, it pushes the L-shaped support rod 223 through the annular mounting plate 22, causing the adjusting rope seat 222 to drag the adjusting rope 122 to gradually extend and drive the rope winding wheel 121 to rotate. The rotation of the rope winding wheel 121 drives the valve shaft of the sampling valve 12 to rotate, and thus the sampling valve 12 gradually closes.

[0037] As the sampling work continues, the amount of samples inside the sampling bucket 1 gradually increases, causing the sinking height of the sampling bucket 1 to also increase. At the same time, the closing degree of the sampling valve 12 gradually increases, leading to a gradual decrease in the sampling rate and a reduction in the sinking speed of the sampling bucket 1 until the sampling valve 12 closes, at which point the sampling bucket 1 automatically stops the sampling work;

[0038] After the staff observes that the sampling bucket 1 has descended to the water surface, they start timing. When the predetermined sampling time is reached, they can control the lifting device to lift the sampling bucket 1. Subsequently, the staff can pour the samples inside the sampling bucket 1 into the storage device. Finally, the staff rotates the sampling valve 12 to open it again and winds the adjusting rope 122 around the rope winding wheel 121.

[0039] During the actual application of this device, the standard sampling volume of the sampling bucket 1 is half of its volume, but its sampling volume is greater than the sampling standard, thereby avoiding the situation of insufficient sample sampling volume.

[0040] During the actual application of this device, after the sampling is completed, although the sampling valve 12 is in a closed state, since the tightening force required for the sampling valve 12 to be completely closed is relatively large, the buoyancy of the floating swim ring 221 is not sufficient to completely tighten it. Therefore, in actual application, after the buoyancy of the floating swim ring 221 closes the sampling valve 12, since the sampling valve 12 is not completely tightened, it is normal for it to have dripping or small water flows. After the sampling bucket 1 is completely lifted, the dripping or leakage amount of the sample is small and will not cause a large change in the total sampling amount of the sample, ensuring sufficient sampling volume.
