Description

Technical Field

[0001] This utility model relates to the field of groundwater collection technology, and in particular to a groundwater collector for hydrogeological and environmental engineering. Background Technology

[0002] Hydrogeology began with the search for and utilization of groundwater sources. Theoretical research gradually developed around practical applications. Engineering geology is the science of investigating, studying and solving geological problems related to human activities and various engineering constructions. In hydrogeological and environmental engineering, groundwater needs to be collected and tested frequently to determine changes in groundwater quality. This usually requires the use of groundwater samplers.

[0003] A search revealed that application number CN201420220473.8 discloses a groundwater collector.

[0004] The technical solution has the following drawbacks when used:

[0005] 1. During the lifting process after water collection, the lack of a sealing function for the inner and outer water inlets makes it easy to tip over if it collides or comes into contact with the surrounding environment, thus spilling the water sample collected inside and requiring collection again, which is quite inconvenient.

[0006] 2. The inlet and outlet of the water inlet do not have the function of intercepting and filtering impurities in the groundwater, which will cause certain interference to the analysis of groundwater entering the sampling box and cannot guarantee the sensitivity and accuracy of the groundwater analysis. Utility Model Content

[0007] The purpose of this utility model is to solve the problems in the background technology by proposing a groundwater collector for hydrogeological and environmental engineering.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A groundwater sampler for hydrogeological and environmental engineering includes:

[0010] Sampling box;

[0011] Two sampling tubes are fixedly connected to the upper and lower sides of the sampling box, respectively;

[0012] The sampling assembly includes two horizontal plates symmetrically fixedly installed inside a sampling box. A bidirectional lead screw is rotatably installed between the two horizontal plates. Two sliders are symmetrically connected to the surface of the bidirectional lead screw with reverse threads. Each of the two horizontal plates has a sealing plate on its opposite side, and the two sealing plates are respectively positioned opposite to two sampling tubes. Two right-angle rods are fixedly installed between each sealing plate and its corresponding slider, and the right-angle rods slide through the surface of the corresponding horizontal plate. A rotating shaft is fixedly inserted through both ends of the bidirectional lead screw. A drive motor for driving the rotating shaft to rotate is installed on the top of the sampling box.

[0013] Self-cleaning filter components are used to intercept particulate matter in groundwater outside the sampling box.

[0014] Preferably, the self-cleaning filter assembly includes two filter plates that are fixedly installed at opposite ends of two sampling tubes, and the filter plates are movably sleeved on the surface of the rotating shaft. Multiple scrapers are attached to opposite sides of the two filter plates, and the scrapers are fixedly installed on the surface of the rotating shaft.

[0015] Preferably, the drive motor is fitted with a waterproof housing, and both sides of the waterproof housing are fixed to the top of the sampling box by right-angle brackets.

[0016] Preferably, each of the two sealing plates is provided with a rubber sealing ring on its opposite side, and the rubber sealing ring is fixedly installed in the sampling box and concentrically arranged with the sampling tube.

[0017] Preferably, springs are connected to the opposite sides of the two sealing plates and the corresponding cross plates.

[0018] Preferably, a semi-lifting ring is fixedly installed on the top of both right-angle frames, and a slot is provided on the inner top of the semi-lifting ring.

[0019] Compared with existing technologies, the advantages of the groundwater collector for hydrogeological engineering provided by this utility model are as follows:

[0020] 1. By controlling the rotating shaft and the bidirectional lead screw to rotate forward and backward by the drive motor, the two sealing plates can be moved towards each other and away from each other. This allows for the opening and closing of the two sampling tubes during and after groundwater sampling, so that when the sampling box is lifted, the sample water inside the sampling box will not spill due to collision, greatly improving the convenience of groundwater sampling.

[0021] 2. By setting up filter plates and scrapers, when the two sealing plates move towards each other to sample groundwater, the two bidirectional screws controlled by the drive motor can intercept impurities in the groundwater outside the sampling box, so as to prevent impurities from entering the sampling box and interfering with the subsequent analysis results. In addition, each scraper can be driven to move in a circular motion on the surface of the filter plate at the same time, continuously cleaning the impurities on the surface of the filter plate, thereby effectively preventing the filter plate from being blocked by impurities.

[0022] In summary, this invention, by controlling the forward and reverse rotation of the bidirectional lead screw via a drive motor, achieves the opening and closing of the two sampling tubes by the two sealing plates respectively. This prevents the sample water inside the sampling box from tipping over and leaking due to collision when the sampling box is lifted, greatly improving the convenience of groundwater sampling. At the same time, the use of a filter plate with self-cleaning and anti-clogging function can intercept impurities in the groundwater outside the sampling box during groundwater sampling, preventing impurities from entering the sampling box and interfering with subsequent analysis results.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figures 1 to 4 A groundwater sampler for hydrogeological and environmental engineering, comprising:

[0030] Sampling box 1; two sampling tubes 2, respectively fixedly connected to the upper and lower sides of sampling box 1; sampling assembly, including two horizontal plates 3 symmetrically fixedly installed inside sampling box 1; a bidirectional lead screw 4 rotatably installed between the two horizontal plates 3; two sliders 5 symmetrically connected to the surface of the bidirectional lead screw 4 with reverse threads; sealing plates 7 are provided on opposite sides of the two horizontal plates 3, and the two sealing plates 7 are respectively arranged opposite to the two sampling tubes 2; rubber sealing rings 13 are provided on opposite sides of the two sealing plates 7, and the rubber sealing rings 13 are fixedly installed inside sampling box 1 and concentrically arranged with the sampling tubes 2; the sealing rings 13 can increase the sealing between the two sealing plates 7 and the end contact surfaces of the two sampling tubes 2 respectively.

[0031] Two right-angle rods 6 are fixedly installed between each sealing plate 7 and its corresponding slider 5, and the right-angle rods 6 slide through the surface of the corresponding horizontal plate 3. The two ends of the bidirectional screw 4 are fixedly connected to the rotating shaft 9. The top of the sampling box 1 is equipped with a drive motor 12 for driving the rotating shaft 9 to rotate. After the sampling box 1 is lowered into the groundwater by the hoisting rope, the external power supply is turned on and the drive motor 12 is started to control the bidirectional screw 4 to rotate forward through the rotating shaft 9. This allows the two sliders 5 to move towards each other through the two right-angle rods 6, opening the two sampling tubes 2 and allowing groundwater to enter the sampling box 1 through the sampling tubes 2. After sampling, the bidirectional screw 4 is reversed by the drive motor 12, causing the two sealing plates 7 to move away from each other until they press against the ends of the two sampling tubes 2, thus blocking the sampling tubes 2. This prevents the sample water in the sampling box 1 from spilling due to collision when the sampling box 1 is lifted, greatly improving the convenience of groundwater sampling.

[0032] The self-cleaning filter assembly is used to intercept particulate matter in groundwater outside the sampling box 1. The self-cleaning filter assembly includes two filter plates 14 that are fixedly installed at opposite ends of two sampling tubes 2, and the filter plates 14 are movably sleeved on the surface of the rotating shaft 9. Multiple scrapers 15 are attached to the opposite sides of the two filter plates 14, and the scrapers 15 are fixedly installed on the surface of the rotating shaft 9. By setting the filter plates 14, it is possible to prevent impurities from entering the sampling box 1 when the sampling tube 2 samples groundwater, which would interfere with the subsequent analysis results. When the drive motor 12 controls the rotating shaft 9 to rotate, it will also drive each scraper 15 to rotate in a circle to clean the impurities on the surface of the filter plate 14, thereby effectively preventing the filter plate 14 from being blocked by impurities.

[0033] Furthermore, the drive motor 12 is externally fixed with a waterproof housing 11. Both sides of the waterproof housing 11 are fixed to the top of the sampling box 1 via right-angle brackets 10. The waterproof housing 11 provides a certain degree of protection for the drive motor 12. When the drive motor 12 is powered on, one end of the cable can be passed through the waterproof housing 11 and electrically connected to the drive motor 12, and the other end can be connected to an external power source. The cable should also be a waterproof cable. The tops of the two right-angle brackets 10 are jointly fixed with a semi-hanging ring 16. The inner top of the semi-hanging ring 16 has a slot 17, which can effectively ensure the stability of the connection between the external hanging rope and the semi-hanging ring 16 when the external hanging rope is connected to the semi-hanging ring 16, so as to prevent the hanging rope from sliding on the semi-hanging ring 16.

[0034] Furthermore, springs 8 are connected to the opposite sides of the two sealing plates 7 and the corresponding horizontal plates 3. When the bidirectional screw 4 rotates forward, causing the two sliders 5 and the two sealing plates 7 to move towards each other, the springs 8 are compressed. When the two sliders 5 disengage from the threads of the bidirectional screw 4, the two sliders 5 remain in contact with the threads on the bidirectional screw 4 under the tension of the two springs 8. At this time, the two sealing plates 7 will neither continue to move towards each other nor move away from each other, thus keeping the two sampling tubes 2 in an open state. Meanwhile, the rotating shaft 9 holds... Continuing to rotate forward will not have any effect, but when the rotating shaft 9 continues to rotate, it will drive each scraper 15 to continuously rotate in a circular motion, so as to continuously clean the surface of the filter plate 14 during the sampling process. Conversely, when the bidirectional lead screw 4 needs to be reversed to control the two sealing plates 7 to move in opposite directions after sampling, the threads on the bidirectional lead screw 4 will not abut against the two sliders 5. Then, with the assistance of the pulling force of the two springs 8, the two sliders 5 will be pulled again to re-engage with the threads of the bidirectional lead screw 4, so as to realize the two sealing plates 7 moving in opposite directions until the two sampling tubes 2 are blocked respectively.

[0035] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
