Technical Field

[0001] The invention relates to the technical field of hydrogeological drilling, in particular to a hydrogeological drilling layered water-stopping device. Background Art

[0003] The existing stratified water-stopping device can realize the function of stratified water extraction, but when facing an aquifer with flowing water, it cannot accurately measure the water flow and water level of the aquifer; and the water temperature is generally measured after the water sample is extracted to the ground, which has a lag and leads to inaccurate water temperature measurement results.

[0015] The rotating shaft is provided with an electromagnetic clutch on the mounting seat and is connected to the rotating shaft via the electromagnetic clutch;

[0016] The driving assembly defines a power chamber between the uppermost partition and the top of the collection tube. The driving assembly is arranged in the power chamber and is connected to the rotating shaft.

[0017] Furthermore, the blocking member includes:

[0018] The blocking portion is in the shape of a parallelogram and is adapted to the shape of the water inlet or outlet, and the two sides of the blocking portion are oblique edges;

[0019] The connecting part has one end connected to the blocking part and the other end connected to the elastic connecting component; when the rotating shaft rotates in the forward direction, the blocking part is inserted into the water inlet or water outlet along the straight line where the hypotenuse is located, and the elastic connecting component is stretched outward and the outer side surface of the connecting part is tightly fitted with the inner side surface of the collection tube through elastic force; when the rotating shaft rotates in the reverse direction, the blocking part moves out from the water inlet or water outlet along the straight line where its hypotenuse is located, and the elastic connecting component is compressed inward.

[0020] Furthermore, the elastic connection assembly includes:

[0021] a bottom plate, fixedly connected to the connecting portion;

[0022] Two side panels are arranged perpendicular to the bottom panel on the left and right sides of the bottom panel, and a mounting chamber is formed between the two side panels and the bottom panel;

[0023] The spring column is arranged in the installation chamber, one end of which is connected to the bottom plate and the other end is connected to the piston plate, and the piston plate is slidably connected to the two side plates; the piston plate is connected to the mounting seat through a connecting rod.

[0024] Furthermore, a slide rail is provided on the inner side surface of the side plate in a direction perpendicular to the bottom plate, and the piston plate is slidably connected to the slide rail.

[0025] Furthermore, the rotating shaft is rotatably connected to the plurality of partitions via a first bearing, and the top end of the rotating shaft is rotatably connected to the top end of the collecting tube via a second bearing.

[0026] Furthermore, the driving component includes:

[0027] The driving motor is arranged on the uppermost partition plate, and the output end of the driving motor is connected to the driving gear. The rotating shaft is provided with a driven gear, and the driving gear is meshed with the driven gear.

[0028] Furthermore, the drilling mechanism includes:

[0029] The rotary motor is arranged at the bottom of the collecting tube, and the output end of the rotary motor is connected to the drill bit through a coupling.

[0030] Furthermore, the collection unit includes: a temperature sensor, a water level measuring instrument and a flow sensor arranged in the collection chamber.

[0031] The present invention discloses the following technical effects:

[0032] 1. The collection chamber is provided with a water inlet and a water outlet, which are sealed or opened by a rotating opening and closing mechanism. When there is flowing water in the aquifer, the water inlet and the water outlet can be opened to allow the flowing water to pass through the collection chamber, thereby realizing the detection of the water flow, water level and water temperature data of the flowing water. Since the detection data are collected in real time, the detection results are relatively accurate.

[0033] 2. The rotary opening and closing mechanism has a sealing portion adapted to the shape of the water inlet and outlet and an elastic connecting component. The sealing portion adopts a parallelogram structure design. When the rotating shaft moves in the forward direction, it can be inserted into the water inlet and outlet along the oblique edge, and the elastic connecting component is used to make the outer side of the connecting portion fit tightly with the inner side of the collection tube to achieve a seal. During the hydrogeological drilling process, it can prevent external soil and water from entering the interior of the device. When the rotating shaft moves in the reverse direction, it can overcome the elastic force of the elastic connecting component and move out of the water inlet and outlet along the oblique edge. The parallelogram-shaped sealing portion cooperates with the elastic connecting component to enable the sealing portion to move in the forward direction along the oblique edge, smoothly enter the water inlet and outlet, and maintain a high degree of sealing. It can also move in the reverse direction along the oblique edge, overcome the elastic force of the elastic connecting component and move out of the water inlet and outlet. It has a simple structure, is easy to operate, and has strong stability.

[0034] 3. The present invention can independently detect data from different aquifers through the structures within each collection chamber. When data collection is required for a particular aquifer, the electromagnetic clutch can be activated to connect the rotating shaft to the mounting base, thereby opening and closing the water inlet and outlet. When data collection is not required for a particular aquifer, the electromagnetic clutch can be deactivated to separate the rotating shaft from the mounting base. The rotating shaft then idles while the mounting base remains stationary. This structure provides high flexibility for data collection from multiple aquifers and expands the device's applicability.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] like Figure 1-Figure 5 As shown, an embodiment of the present invention provides a hydrogeological drilling layered water-stopping device, comprising:

[0045] The collection tube 1 defines a multi-layer collection chamber 101 from top to bottom. In this embodiment, the collection chamber 101 is provided with two layers, including an upper collection chamber 101 and a lower collection chamber 101. The collection chamber 101 has a water inlet 102 and a water outlet 103 on its left and right sides, respectively. The positions of the water inlet 102 and the water outlet 103 are roughly corresponding.

[0046] The drilling mechanism is arranged at the bottom of the collection tube 1;

[0047] A rotary opening and closing mechanism is disposed within the collection chamber 101. Both the water inlet 102 and the water outlet 103 are provided with a blocking member 2. The rotary opening and closing mechanism is connected to the blocking members 2 within the water inlet 102 and the water outlet 103, respectively. When the rotary opening and closing mechanism rotates, it can drive the blocking member 2 to seal the water inlet 102 or move away from the water inlet 102, and can drive the blocking member 2 to seal the water outlet 103 or move away from the water outlet 103.

[0048] The collection unit is arranged in the collection chamber 101 and is used to collect water flow, water level and water temperature data; in some other embodiments, the collection unit can also be used to collect water quality data, and the specific setting of the collection unit can be flexibly adjusted according to actual conditions.

[0049] In this embodiment, a plurality of partitions 3 are arranged in parallel from top to bottom in the collection tube 1 . The partitions 3 are made of corrosion-resistant and waterproof material, and a collection chamber 101 is formed between adjacent partitions 3 .

[0050] In this embodiment, the rotary opening and closing mechanism includes:

[0051] The blocking member 2 is used to block the water inlet 102 or the water outlet 103;

[0052] An elastic connecting component 7, one end of which is connected to the blocking member 2, and the other end of which is connected to the mounting seat 8;

[0053] The rotating shaft 5 and the mounting base 8 are provided with an electromagnetic clutch 6 and connected to the rotating shaft 5 through the electromagnetic clutch 6;

[0054] The driving assembly defines a power chamber 104 between the uppermost partition 3 and the top of the collecting tube 1 . The driving assembly is disposed in the power chamber 104 and is in transmission connection with the rotating shaft 5 .

[0055] In this embodiment, the blocking member 2 includes:

[0056] The blocking portion 201 is in the shape of a parallelogram and matches the shape of the water inlet 102 or the water outlet 103. Both sides of the blocking portion 201 are beveled edges.

[0057] The connecting part 202 is connected to the blocking part 201 at one end and to the elastic connecting component 7 at the other end. The width of the connecting part 202 is greater than the width of the blocking part 201. When the rotating shaft 5 rotates forward, the blocking part 201 is inserted into the water inlet 102 or the water outlet 103 along the straight line where the hypotenuse is located. The elastic connecting component 7 is stretched outward and the outer side surface of the connecting part 202 is tightly fitted with the inner side surface of the collecting tube 1 through elastic force. The outer side surface of the connecting part 202 is provided with a sealing ring. When the connecting part 202 is tightly fitted with the collecting tube 1, the gap can be sealed. The blocking part 201 and the connecting part 202 work together to complete the blocking of the water inlet 102 and the water outlet 103. When the rotating shaft 5 rotates reversely, the blocking part 201 moves out from the water inlet 102 or the water outlet 103 along the straight line where its hypotenuse is located, and the elastic connecting component 7 is compressed inward.

[0058] In this embodiment, the elastic connection component 7 includes:

[0059] Bottom plate 701, fixedly connected to connecting portion 202;

[0060] Two side panels 702 are perpendicular to the bottom panel 701 and are arranged on the left and right sides of the bottom panel 701 , and an installation chamber is formed between the two side panels 702 and the bottom panel 701 ;

[0061] The spring column 703 is arranged in the installation chamber, one end of which is connected to the bottom plate 701 and the other end is connected to the piston plate 704. The piston plate 704 is slidably connected to the two side plates 702; the piston plate 704 is connected to the mounting seat 8 through the connecting rod 9.

[0062] In this embodiment, a limiting column (not shown) is provided at the end of the slide rail 705 close to the rotating shaft 5 to prevent the piston plate 704 from separating from the slide rail 705 .

[0063] In this embodiment, a slide rail 705 is provided on the inner side surface of the side plate 702 in a direction perpendicular to the bottom plate 701 , and the piston plate 704 is slidably connected to the slide rail 705 .

[0064] When the blocking portion 201 enters the water inlet 102 or the water outlet 103 or moves out of the water inlet 102 or the water outlet 103, the elastic force of the spring column 703 will change. The above structure allows the spring column 703 to only generate elastic force changes perpendicular to the direction of the bottom plate 701 without bearing torque. When the rotating shaft 5 rotates, the piston plate 704 transmits the torque to the slide rail 705, and the structural stability is relatively strong.

[0065] In this embodiment, the rotating shaft 5 is rotatably connected to the plurality of partitions 3 via a first bearing 10. The top end of the rotating shaft 5 is rotatably connected to the top of the collection tube 1 via a second bearing 11. A sealing gasket is positioned above the first bearing 10 to prevent water in the upper collection chamber 101 from leaking through the first bearing 10 into the lower collection chamber 101. In other embodiments, other sealing structures may be employed, as long as they maintain the functionality of the first bearing 10 and the sealing properties of the collection chamber 101.

[0066] In this embodiment, the driving assembly includes:

[0067] The driving motor 12 is disposed on the uppermost partition 3 , and an output end thereof is connected to a driving gear 13 . A driven gear 14 is disposed on the rotating shaft 5 , and the driving gear 13 is meshed with the driven gear 14 .

[0068] In this embodiment, the drilling mechanism includes:

[0069] The rotary motor 15 is provided at the bottom of the collecting tube 1 , and the output end of the rotary motor 15 is connected to the drill bit 4 through a coupling.

[0070] In this embodiment, the collection unit includes a temperature sensor, a water level meter, and a flow rate sensor, all disposed within collection chamber 101. Each sensor can be fixed to partition 3 or positioned on the inner wall of collection chamber 101. The specific placement is not limited and can be flexibly adjusted based on actual circumstances.

[0071] The specific working process is as follows:

[0072] The rotary motor 15 drives the drill bit 4 to drill hydrogeology until the target depth is reached (it should be noted that downward drilling also requires other professional equipment and does not rely solely on the rotary motor 15 and the drill bit 4. The relevant professional equipment is existing technology and will not be described here).

[0073] Initially, the sealing members 2 are located within the water inlet 102 and the water outlet 103, respectively, to maintain the overall sealing of the equipment during the aforementioned drilling process. When it is necessary to collect a water sample from the aquifer corresponding to the lower collection chamber 101, the electromagnetic clutch 6 in the lower collection chamber 101 is opened, coupling the mounting base 8 with the rotating shaft 5, while the electromagnetic clutch 6 in the upper collection chamber 101 remains closed.

[0074] The drive motor 12 is started, and the drive motor 12 drives the rotating shaft 5 to rotate through the driving gear 13 and the driven gear 14. The rotating shaft 5 drives the mounting base 8 to rotate through the electromagnetic clutch 6. The mounting base 8 drives the elastic connection components 7 on both sides to rotate at the same time through the connecting rod 9.

[0075] Regarding the blocking member 2 in the water inlet 102 (left side in the figure), the connecting rod 9 drives the blocking member 2 to rotate counterclockwise via the elastic connecting assembly 7. During this rotation, at the beveled edge of the blocking member 2, the sidewall of the water inlet 102 (also a beveled edge) exerts a reaction force on the blocking member 2 toward the collection chamber 101, causing the blocking member 2 to withdraw from the water inlet 102. During this process, the spring column 703 in the elastic connecting assembly 7 is compressed, causing the piston plate 704 to move linearly along the slide rail 705, and the blocking member 2 and the elastic connecting assembly 7 as a whole to move closer to the rotating shaft 5. The connecting rod 9 continues to drive the blocking member 2 to rotate counterclockwise until the blocking member 2 is completely removed from the water inlet 102. During the above process, the blocking member 2 in the water outlet 103 also moves synchronously and moves out of the water outlet 103. For the collection chamber 101, the side length where the water inlet 102 and the water outlet 103 are located is slightly longer. Therefore, when the blocking member 2 is moved out of the water inlet 102 and the water outlet 103, the blocking member 2 will first slide for a distance with the side wall of the collection chamber 101 where the water inlet 102 and the water outlet 103 are located, and then separate from it, stay in the collection chamber 101 and do not contact the other two side walls of the collection chamber 101. The spring column 703 will also return to its initial state.

[0076] After the water inlet 102 and the water outlet 103 are fully opened, the collection chamber 101 is connected to the flowing water in the aquifer, and the flowing water can flow through the collection chamber 101, and then the water flow, water level and water temperature data are collected through the collection unit.

[0077] After the collection is complete, the sealing member 2 can be resealed by reversing the above steps, resealing the water inlet 102 and outlet 103, and then removing the device from the hydrogeological site. After the water inlet 102 and outlet 103 are sealed, some of the flowing water in the aquifer is stored in the collection chamber 101, which can be extracted at the surface for further analysis of water quality and other data.

[0078] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
