Description

Technical Field

[0001] The utility model relates to the technical field of ecological environment monitoring, and in particular to a bailer pipe well washing device with double water locks and a winch capable of being expanded as needed. Background Art

[0002] Sample collection is the most basic and important task in groundwater monitoring. Collecting representative samples is the prerequisite for us to accurately grasp the groundwater environmental quality status and the dynamic distribution changes of pollutants in groundwater bodies. Groundwater sampling is to collect fresh "representative water samples" from the aquifers immediately surrounding the monitoring wells. The water in the monitoring well screen slowly exchanges and renews with the groundwater in the surrounding aquifers, and is flowing living water, while the water in the well pipe is in a stagnant static state, which is the so-called well pipe water accumulation. Well pipe water accumulation is not representative, so the well must be washed before sampling to remove the well pipe water accumulation, ensure the stability of the groundwater flow field near the monitoring well, and collect "fresh" groundwater that flows from the aquifer into the well without sufficient contact with the well pipe and air as a representative water sample. Therefore, standardized well washing before sampling is a key step in groundwater sampling.

[0003] Common groundwater well washing devices include Belle tubes, low-flow submersible pumps, inertial pumps, and peristaltic pumps. The advantages and disadvantages of each device are summarized as follows:

[0004] Traditional Belle tube well-washing devices are inexpensive, lightweight, easy to operate, and unaffected by sampling depth. However, they have a small single-sample volume, poor water-stopping effect from the circular water-stop valve, are prone to leaks when the water is turbid or hits the well wall during lifting, and manually pulling the Belle tube consumes manpower and has low well-washing efficiency. They are suitable for various contaminated plots and require a well diameter greater than 4 cm.

[0005] The submersible pump well washing device has the characteristics of large sampling flow, high head, and fast well washing speed. The device needs to be used with supporting instruments such as sampling pumps, generators, cables, water pipes, ropes, tripods, etc., and has the disadvantages of many auxiliary equipment, being bulky, difficult to carry and disassemble, etc., and is not suitable for the collection of VOCs samples. It requires the well diameter to be greater than 5cm and the sampling depth to be ≤90m. When washing deep wells, the water pipe is easily deformed during the lifting process after being filled with water, and is stretched and fallen. At this time, if the lifting speed of the water pipe, submersible pump and wire is slightly different, or the water pipe, cable and rope are entangled with each other, it will cause blockage of the well. The blockage point is often located at the connection between the pump head and the water pipe. Since the submersible pump is equipped with a check valve, the water pipe is always kept filled with water. Once the well is blocked, it is difficult to solve it by pulling it up, and brute force pulling may even cause the water pipe to break or the interface to fall off, causing the submersible pump to fall to the bottom of the well, resulting in the scrapping of the monitoring well.

[0006] Inertial pumps and peristaltic pumps are characterized by low price, simple structure, and easy disassembly and assembly. However, inertial pumps are not suitable for collecting VOCs samples. They are suitable for sampling wells of any caliber and the sampling depth is ≤30m. Peristaltic pumps are not suitable for VOCs sampling. They are suitable for sampling wells of any caliber and the sampling depth is ≤10m. Utility Model Content

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] Example 1

[0024] like Figure 1 、 Figure 2As shown, a double-water-locking Bailer pipe well washing device with a winch that can be expanded on demand includes: a double-water-locking Bailer pipe 1 and a portable winch 2, wherein a plurality of double-water-locking Bailer pipes 1 of corresponding calibers are connected in series on the parachute 210 of the portable winch 2 according to the inner diameter of the monitoring well and the water volume in the well, and a baffle water-stop valve 120 and a conical water-stop valve 130 are provided above the water inlet 111 in the double-water-locking Bailer pipe 1. The baffle water-stop valve 120 is located above the conical water-stop valve 130, and the baffle water-stop valve 120 is opened in one direction from bottom to top, that is, when the double-water-locking Bailer pipe 1 is in a forward vertical state, the water sample cannot flow from the baffle water-stop valve 120 to the conical water-stop valve 1 30. The baffle water-stop valve 120 serves as a first-level water lock, and the conical water-stop valve 130 is opened unidirectionally from bottom to top, that is, double water-locking. When the Belle tube 1 is in a forward vertical state, the water sample cannot flow from the conical water-stop valve 130 to the water inlet 111. The conical water-stop valve 130 serves as a second-level water lock to achieve double water lock, effectively preventing water sample dripping. When taking water, the water sample can enter from the water inlet 111, and then rely on the buoyancy (thrust) of the water to open the conical water-stop valve 130 unidirectionally from bottom to top. Of course, when the water sample flows from the conical water-stop valve 130 to the baffle water-stop valve 120, the baffle water-stop valve 120 can be opened unidirectionally from bottom to top by relying on the buoyancy (thrust) of the water to achieve water taking.

[0025] A portable winch is used in combination with a double water-locking beyler tube 1 to achieve electric well washing. In addition, the baffle water-stop valve 120 in the double water-locking beyler tube 1 serves as a first-level water lock, and the conical water-stop valve 130 serves as a second-level water lock, thereby achieving a double water-locking function and effectively preventing water sample dripping. The portable winch 2 is then used to solve the problems of water leakage in the original beyler tube device, excessive weight of the submersible pumping device, and manpower consumption. According to the inner diameter of the monitoring well and the amount of water in the well, double water-locking beyler tubes 1 of different diameters are used and connected in series as needed, thereby achieving on-demand capacity expansion and reducing the occurrence of water leakage, greatly improving the well washing efficiency. The well washing efficiency can be increased by 2 to 6 times, and the 12-hour well washing task can be shortened to less than 2 hours. The device is light and easy to assemble, with high well washing efficiency, is suitable for all types of polluted plots, is not affected by the sampling depth, and can effectively avoid the scrapping of monitoring wells due to well blockage.

[0026] Example 2

[0027] like Figure 2 As shown, this embodiment is a further improvement on the basis of embodiment 1, specifically as follows:

[0028] The double water-locking baile tube 1 comprises: a water intake pipe 110, a baffle water stop valve 120 and a conical water stop valve 130. The upper end opening of the water intake pipe 110 is connected to a connector 140 for connecting an umbrella rope 210.

[0029] The baffle water stop valve 120 includes: a baffle 121, which is arranged in the water intake pipe 110, and the cross-sectional dimensions of the baffle 121 are the same as the inner cross-sectional dimensions of the water intake pipe 110. The entire outer circumference of the baffle 121 is sealed and connected to the inner wall surface of the water intake pipe 110, that is, it is watertight. A water outlet 1211 is provided in the middle of the baffle 121, and a cover plate 122 is fixed above the baffle 121 and can move up and down to open and close the water outlet 1211. The size of the cover plate 122 is smaller than that of the baffle 121. The baffle 121 is provided with a limiting structure 123 for limiting the upward range of movement of the cover plate 122, that is, preventing the cover plate 122 from being misplaced to ensure that the cover plate 122 can open and close the water outlet 1211;

[0030] The conical water stop valve 130 includes a conical plug 131. The lower end of the water intake pipe 110 is narrowed into a conical shape. The lower end of the conical section of the water intake pipe 110 has a water inlet 111. The size of the conical plug 131 is larger than the inner diameter of the water inlet 111. The conical plug 131 is arranged in the conical section at the lower end of the water intake pipe 110. The conical outer peripheral surface of the conical plug 131 is in contact with the conical inner wall surface of the conical section at the lower end of the water intake pipe 110. A spacer 132 is arranged between the conical plug 131 and the baffle 121 to limit the upward movement range of the conical plug 131. The spacer 132 is fixed to the inner wall surface of the water intake pipe 110.

[0031] When taking water, the water sample can enter from the water inlet 111, and then rely on the buoyancy (thrust) of the water to make the conical plug 131 move upward, so that the water sample can flow to the baffle water stop valve 120 through the conical section. Of course, when the water sample flows from the conical water stop valve 130 to the baffle 121, the water passes through the water outlet 1211 on the baffle 121 and relies on the buoyancy (thrust) of the water to push the cover plate 122 upward, so that the water sample can pass through the water outlet 1211 into the space above the baffle water stop valve 120 in the water intake pipe 110, thereby achieving water collection;

[0032] When water extraction is finished, the double water-locking Belle tube 1 is lifted upward and out of the water surface, and the cover plate 122 closes the water outlet 1211 by gravity. Similarly, the conical plug 131 closes the water inlet 111 by gravity, achieving double water locking and effectively preventing water sample dripping.

[0033] Example 3

[0034] like Figure 2 As shown, this embodiment is a further improvement on the basis of embodiment 2, specifically as follows:

[0035] The limiting structure 123 is a plurality of clips, which are distributed around the cover plate 122, and the lower ends of the clips are fixed to the baffle 121, that is, the upward movement range of the cover plate 122 is limited by the plurality of clips. Of course, the limiting structure 123 is not limited to this. It is also possible to design a plurality of limiting holes on the cover plate 122, and then arrange a limiting rod in each limiting hole. The lower end of the limiting rod is fixed to the baffle 121, and the lower end of the limiting rod has a limiting ring.

[0036] Example 4

[0037] like Figure 1 、 Figure 2 As shown, this embodiment is a further improvement on the basis of embodiment 2 or 3, specifically as follows:

[0038] The connector 140 is connected to the parachute cord 210 via a spring buckle 220 . The connector 140 is a plastic connector. The connector 140 is threadedly connected to the water intake pipe 110 , making it easy to disassemble and open the water intake pipe 110 .

[0039] Example 5

[0040] like Figure 1 As shown, this embodiment is a further improvement on the basis of any one of the embodiments 1 to 4, specifically as follows:

[0041] The caliber of the double water-locking Beyler tube 1 is 35mm, 60mm or 90mm, which is suitable for various types of polluted plots. The well diameter is required to be greater than 4cm and is not affected by the sampling depth. The length of the double water-locking Beyler tube 1 is 1000mm. According to the inner diameter and water volume of the monitoring well, a suitable double water-locking Beyler tube 1 is selected, and the double water-locking Beyler tube 1 is connected in series as needed using the parachute rope 210 to achieve on-demand capacity expansion function. For example: 4 double water-locking Beyler tubes 1 with a length of 1000mm and an inner diameter of 60mm are connected in series up and down, and 12L of water is pumped at a time, 2 minutes / time, and it takes 2 hours.
