Description

Technical Field

[0001] The embodiments of the present invention relate to the field of surveying equipment technology, specifically to a water conservancy and hydropower construction surveying equipment utilizing extraction tools. Background Technology

[0002] Water conservancy and hydropower construction is a specialized field of engineering construction, encompassing the construction and implementation of water conservancy facilities, including earthwork, concrete and other structural construction, and the installation of electromechanical equipment. The technical requirements for water conservancy and hydropower construction include strengthening the seepage prevention and frost resistance of structures, complex low-level treatment, and diversion and interception design. Specialized plans need to be developed in conjunction with hydrogeological conditions. Water conservancy and hydropower engineering construction is similar to general civil engineering construction, and some construction plans and construction machinery can be used interchangeably. However, in the specific construction process, it is also necessary to coordinate with the local hydrological environment. Most water conservancy projects need to undertake the tasks of water retention, water storage, and water discharge. During the corresponding water conservancy construction process, it is necessary to conduct surveys of the river, lake, coastal, and groundwater environment in the construction environment to determine the area and water quality of waterways, lakes, and other water bodies.

[0003] When it is necessary to test the water quality of a water body, it is usually necessary to use extraction tools to take samples from different depths of the water flow layer to determine the water quality problems, so as to facilitate the special treatment of the water in the water body during the construction of water conservancy and hydropower projects.

[0004] When surveying flowing water bodies, it is also necessary to sample the sediment on the riverbed at the bottom of the water body to determine whether there is a problem of pollutant accumulation in the water body, so as to carry out effective and targeted water pollution detection operations.

[0005] Existing extraction tools are difficult to use to sample solids at the bottom of the water body and liquids in different flow layers during a single dive, which affects the effectiveness of water body surveys. Summary of the Invention

[0006] To overcome the above-mentioned defects, embodiments of the present invention provide a water conservancy and hydropower construction surveying equipment that utilizes extraction tools, solving the technical problem that the existing method of sampling and surveying solids and liquids inside water bodies using extraction tools is relatively cumbersome.

[0007] This invention provides a water conservancy and hydropower construction surveying equipment utilizing extraction tools, comprising a mounting chassis, a sample detection device mounted on the top of the mounting chassis, and further comprising: A through-rotor is rotatably connected to the mounting housing; An extraction cylinder seat is located directly below the through-rotating cylinder, and the through-rotating cylinder is provided with a movable structure that drives the extraction cylinder seat to move longitudinally at the bottom of the mounting box; An extraction branch tube is slidably connected to the bottom of the extraction cylinder seat.

[0009] At least one embodiment of the present invention provides a water conservancy and hydropower construction surveying equipment using an extraction tool. A partition sleeve is fixedly connected inside the extraction cylinder base. A partition interlayer is provided between the outer wall of the partition sleeve and the inner wall of the extraction cylinder base. A protective mesh layer is provided inside the partition interlayer.

[0010] At least one embodiment of the present invention provides a water conservancy and hydropower construction surveying device using an extraction tool. A sliding groove is provided on the inner wall of the partition sleeve, a gearbox is slidably arranged on the sliding groove, a drive motor is provided on the gearbox, the drive motor is in transmission cooperation with the gearbox, the output end of the gearbox is connected to the extraction screw, and a first electric cylinder is provided inside the partition sleeve for driving the drive motor, the gearbox and the extraction branch pipe to move longitudinally.

[0011] At least one embodiment of the present invention provides a water conservancy and hydropower construction surveying equipment using an extraction tool. The bottom of the gearbox is provided with a mounting base, and the extraction branch pipe is fixedly connected to the mounting base. The extraction branch pipe is provided with a sample outlet.

[0012] At least one embodiment of the present invention provides a water conservancy and hydropower construction surveying device using an extraction tool, wherein a sloped seat is fixedly connected inside the sample outlet, the sloped seat is in contact with the outer wall of the extraction screw, and an inclined discharge groove is provided on the sloped seat.

[0013] At least one embodiment of the present invention provides a water conservancy and hydropower construction surveying device using an extraction tool. The sample collection structure includes a support collar and a semi-circular receiving trough. The support collar is fixedly sleeved on the outer wall of the extraction branch pipe, and the semi-circular receiving trough is placed on the support collar.

[0014] At least one embodiment of the present invention provides a water conservancy and hydropower construction surveying device using an extraction tool. The bottom of the extraction cylinder is provided with a sampling groove, and an annular water-blocking band is provided in the sampling groove. The annular water-blocking band is in contact with the outer wall of the extraction branch pipe.

[0015] At least one embodiment of the present invention provides a water conservancy and hydropower construction surveying device using an extraction tool, which further includes a plunger rod and an extension cylinder seat. The plunger rod is slidably disposed inside the water sample collection cylinder. The bottom of the water sample collection cylinder has multiple water inlet holes. The top of the water sample collection cylinder is fixedly connected to the extension cylinder seat. A counterweight seat is slidably disposed inside the extension cylinder seat. The counterweight seat is connected to the top of the plunger rod.

[0016] At least one embodiment of the present invention provides a water conservancy and hydropower construction surveying device using an extraction tool. The traction drive structure includes a connecting ring and a traction belt. The connecting ring is slidably connected to the slide groove. A second electric cylinder is provided inside the partition sleeve to drive the connecting ring to move longitudinally. The number of cylinders is set to be multiple and the lengths are different. The traction belt corresponds one-to-one with the water sample collection tube. The traction belt passes through the extraction tube seat and the extension tube seat and is fixedly connected to the top of the counterweight seat.

[0017] The beneficial effects of the embodiments of the present invention are as follows: 1. In this invention, when it is necessary to sample solid samples from the bottom of a water body, multiple hollow screws can be used to drive the extraction cylinder seat down to the bottom of the water body, causing the extraction cylinder seat to move to the bottom of the water body, driving the extraction branch tube to extend from the bottom of the extraction cylinder seat, and then allowing the extraction branch tube and extraction screw to extend into the soil layer at the bottom of the water body. The soil sample rises from the extraction branch tube during the rotation of the extraction screw, and then the soil sample is collected through the sample collection structure. After the extraction cylinder seat is removed from the water body, the soil sample is removed from the extraction cylinder seat, and then the presence of pollutants in the soil sample is detected, which facilitates the effective detection of pollutants in the water body.

[0018] 2. In this invention, when it is necessary to sample liquid samples from different water layers in a water body, during the longitudinal movement of the extraction cylinder seat, the connecting ring is driven to maintain longitudinal movement, driving multiple traction belts to move simultaneously. However, because the lengths of the multiple traction belts are not consistent, the multiple traction belts can pull the counterweight seat in sequence, so that the movement time of each counterweight seat is staggered. While the counterweight seat pulls the plunger rod to move, it drives the liquid sample into the water sample collection cylinder. Multiple water sample collection cylinders are used to collect water samples from different water layers in the water body to meet the water body sampling standards. Attached Figure Description

Detailed Implementation The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0022] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0025] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] like Figures 1 to 2 As shown, the present invention discloses a water conservancy and hydropower construction surveying equipment using extraction tools, including a mounting box 1. A sample detection device 2 is provided on the top of the mounting box 1, and multiple fixed sockets 31 are provided on the bottom of the mounting box 1. The fixed sockets 31 can be fixed in a designated position by themselves, or extension rods 32 that engage with the fixed sockets 31 can be used to increase the installation distance of the mounting box 1 and the installation stability.

[0028] like Figures 1 to 2 As shown, in this embodiment, the sample detection device 2 includes a water sample detection module and a soil sample detection module. Both the water sample detection module and the soil sample detection module use the working principle of a chromatograph to detect water samples and soil samples respectively. The water sample detection module uses ion chromatography to detect water samples, while the soil sample detection module uses atomic absorption chromatography to detect pollutants in soil samples. This allows for rapid determination of the pollutants contained in the liquid and solid components of the water body within a short time.

[0029] like Figures 1 to 4 As shown, in this embodiment, a through-rotor 3 is also included. The through-rotor 3 is rotatably connected to the mounting housing 1. A motor drive device 33 is provided on the mounting housing 1. Synchronous pulleys 34 are fixedly sleeved on both the motor drive device 33 and the through-rotor 3. A synchronous belt 35 is provided between the two synchronous pulleys 34 for transmission. When it is necessary to drive the through-rotor 3 to rotate, the motor drive device 33 is started. Through the transmission of the synchronous pulleys 34 and the synchronous belt 35, the through-rotor 3 is driven to rotate on the mounting housing 1, thereby realizing the longitudinal movement of the hollow screw 9.

[0030] like Figures 1 to 7As shown, in this embodiment, the extraction cylinder seat 4 is located directly below the through-rotating cylinder 3. The through-rotating cylinder 3 is equipped with a moving structure that drives the extraction cylinder seat 4 to move longitudinally at the bottom of the mounting housing 1. The moving structure includes a meshing ring sleeve 8, a hollow screw 9, and a threaded cylinder seat 10. The meshing ring sleeve 8 is fixedly connected to the mounting housing 1. The outer wall of the hollow screw 9 is slidably connected to the meshing ring sleeve 8. The extraction cylinder seat 4 is threadedly connected to the hollow screw 9. The threaded cylinder seat 10 is fixedly connected inside the through-rotating cylinder 3, and the threaded cylinder seat 10 is threadedly connected to the hollow screw 9. The upper and lower parts of the multiple hollow screws 9... Both sides are provided with threaded interfaces. After the hollow screw 9 is inserted into the through-rotating cylinder 3, the narrow groove on the outer wall of the hollow screw 9 is first made to fit with the inner wall of the meshing ring sleeve 8, so that the hollow screw 9 will not rotate with the through-rotating cylinder 3. Then, during the rotation, it drives the threaded cylinder seat 10 to rotate, causing the hollow screw 9 to move into the water. By using multiple hollow screws 9 to increase the length of the extraction cylinder seat 4 to descend, the extraction cylinder seat 4 can be lowered to the bottom of the water. Power supply wires can be inserted into the hollow screw 9 to supply power to the electrical equipment inside the extraction cylinder seat 4.

[0031] like Figures 1 to 5 As shown, in this embodiment, a partition sleeve 11 is fixedly connected inside the extraction cylinder seat 4. A partition interlayer is provided between the outer wall of the partition sleeve 11 and the inner wall of the extraction cylinder seat 4. A protective mesh layer 12 is provided inside the partition interlayer. Because the extraction cylinder seat 4 will inevitably collide with debris in the water body during longitudinal movement, the partition sleeve 11 and the protective mesh layer 12 are used to protect the various electrical devices inside the extraction cylinder seat 4, thereby improving the protective performance of the side wall of the extraction cylinder seat 4.

[0032] like Figures 1 to 5 and Figure 7As shown, in this embodiment, the extraction branch tube 5 is slidably connected to the bottom of the extraction tube base 4. An extraction screw 6 is rotatably connected inside the extraction branch tube 5. The extraction screw 6 drives the solid sample to rise inside the extraction branch tube 5. A sample collection structure is provided on the extraction branch tube 5. A sliding groove 13 is provided on the inner wall of the partition sleeve 11. A gearbox 14 is slidably arranged on the sliding groove 13. A drive motor 15 is provided on the gearbox 14. The drive motor 15 and the gearbox 14 are in transmission cooperation. The output end of the gearbox 14 is connected to the extraction screw 6. A mechanism for driving the drive motor 15, gearbox 14 and extraction branch tube 5 is provided inside the partition sleeve 11. After the extraction cylinder 4 descends to the bottom of the water body, the first electric cylinder 16, which moves longitudinally, starts the drive motor 15. Through the transmission of the gearbox 14, the extraction screw 6 rotates inside the extraction branch pipe 5. The output end of the first electric cylinder 16 is connected to the top of the gearbox 14 through a housing. Starting the first electric cylinder 16 can drive the gearbox 14 to move downward on the slide groove 13, so that the extraction branch pipe 5 and the extraction screw 6 are moved out from the bottom of the extraction cylinder 4, and the extraction branch pipe 5 and the extraction screw 6 enter the soil layer at the bottom of the water body together. During the rotation of the extraction screw 6, the soil sample is driven to rise inside the extraction branch pipe 5.

[0033] like Figures 1 to 5 As shown, in this embodiment, a mounting base 17 is provided at the bottom of the gearbox 14, and the extraction branch pipe 5 is fixedly connected to the mounting base 17. A sample outlet 18 is provided on the extraction branch pipe 5, and the soil sample rising in the extraction branch pipe 5 is finally discharged from the extraction branch pipe 5 through the sample outlet 18.

[0034] like Figures 1 to 5 and Figure 7 As shown, in this embodiment, a slope seat 19 is fixedly connected inside the sample outlet 18. The slope seat 19 is in contact with the outer wall of the extraction screw 6. An inclined discharge groove 20 is provided on the slope seat 19. When the soil sample rises from the extraction branch pipe 5, because the soil sample has a certain viscosity, in order to ensure that the soil sample is completely discharged from the extraction branch pipe 5, a protrusion is provided on the side of the slope seat 19 facing the extraction screw 6. After the soil sample on the extraction screw 6 comes into contact with the protrusion, the soil sample is transferred to the slope seat 19 and discharged using the inclined discharge groove 20.

[0035] like Figures 1 to 5 and Figure 7As shown, in this embodiment, the sample collection structure includes a support collar 21 and a semi-circular receiving trough 22. The support collar 21 is fixedly sleeved on the outer wall of the extraction branch pipe 5, and the semi-circular receiving trough 22 is placed on the support collar 21. The soil sample discharged from the inclined discharge trough 20 enters the semi-circular receiving trough 22. The semi-circular receiving trough 22 is used to collect the soil sample, and subsequently, most of the area of ​​the extraction branch pipe 5 can be moved out of the extraction cylinder seat 4. The testing personnel can remove the semi-circular receiving trough 22 from the support collar 21 and test the soil sample in the semi-circular receiving trough 22.

[0036] like Figures 1 to 5 As shown, in this embodiment, the bottom of the extraction cylinder seat 4 is provided with a sample discharge slot, and an annular water-blocking band 23 is provided in the sample discharge slot. The annular water-blocking band 23 is attached to the outer wall of the extraction branch pipe 5. In order to prevent liquid in the water body from entering the extraction cylinder seat 4, the annular water-blocking band 23 can be used to keep the extraction cylinder seat 4 closed and prevent water from entering the extraction cylinder seat 4. In addition, the annular water-blocking band 23 has an expansion capability, which can make the support collar 21 and the semi-circular receiving groove 22 expand the annular water-blocking band 23 and move out of the extraction cylinder seat 4.

[0037] like Figures 1 to 6 As shown, in this embodiment, multiple water sample collection tubes 7 are provided on the outer wall of the extraction tube base 4. The extraction tube base 4 is provided with a traction drive structure that drives the multiple water sample collection tubes 7 to collect water samples in sequence. When the extraction tube base 4 moves to different heights in the water body, the corresponding water sample collection tube 7 is used to collect water samples. When it is necessary to sample the liquid in different water layers in the water body, the plunger rod 24 in the multiple water sample collection tubes 7 is driven to move in sequence through the traction drive structure, so that the multiple water sample collection tubes 7 sample the water body in sequence.

[0038] like Figures 1 to 6 As shown, in this embodiment, a plunger rod 24 and an extension tube seat 26 are also included. The plunger rod 24 is slidably disposed inside the water sample collection tube 7. The bottom of the water sample collection tube 7 is provided with multiple water inlet holes 25. The top of the water sample collection tube 7 is fixedly connected to the extension tube seat 26. A counterweight seat 27 is slidably disposed inside the extension tube seat 26. The counterweight seat 27 is connected to the top of the plunger rod 24. When water needs to enter the water sample collection tube 7, the counterweight seat 27 is pulled to move within the extension tube seat 26, causing the counterweight seat 27 to drive the plunger rod 24 out of the water sample collection tube 7, thereby generating a negative pressure suction force inside the water sample collection tube 7, which attracts the water in the water layer into the water sample collection tube 7. The bottom of the water sample collection tube 7 is provided with multiple baffles 36. The baffles 36 are used to keep the water inlet holes 25 connected to the external environment. Since some debris such as leaves often float on the surface of the water, the baffles 36 can prevent leaves from directly contacting the water inlet holes 25.

[0039] like Figures 1 to 6As shown, in this embodiment, the traction drive structure includes a connecting ring 28 and a traction belt 30. The connecting ring 28 is slidably connected to the slide groove 13. A second electric cylinder 29 is provided in the partition sleeve 11 to drive the connecting ring 28 to move longitudinally. The number of cylinders 29 is set to be multiple and of different lengths. The traction belts 30 correspond one-to-one with the water sample collection tubes 7. The traction belts 30 pass through the extraction tube seat 4 and the extension tube seat 26 and are fixedly connected to the top of the counterweight seat 27. When the second electric cylinder 29 is activated, the connecting ring 28 slides on the slide groove 13, so that the multiple traction belts 30 move together with the connecting ring 28. Since the lengths of the different traction belts 30 are also different, the time for the different traction belts 30 to pull the counterweight seat 27 is also different. This enables the traction operation of different plunger rods 24 at different times, so that multiple water sample collection tubes 7 can sample water samples from different locations in the water body at different times.

[0040] The working principle of this hydraulic and hydropower construction surveying equipment that utilizes extraction tools: When it is necessary to sample the soil layer at the bottom of the water body, multiple spliced ​​hollow screws 9 are used to drive the extraction cylinder 4 to descend, so that the extraction cylinder 4 is close to the soil layer at the bottom of the water body. Then, the drive motor 15 is started, and through the transmission of the gearbox 14, the extraction screw 6 is driven to rotate in the extraction branch pipe 5. The output end of the first electric cylinder 16 is connected to the top of the gearbox 14 through a housing. Activating the first electric cylinder 16 can drive the gearbox 14 to move downward on the slide groove 13, so that the extraction... The branch pipe 5 and the extraction screw 6 are moved out from the bottom of the extraction cylinder seat 4, so that the extraction branch pipe 5 and the extraction screw 6 enter the soil layer at the bottom of the water body together. During the rotation of the extraction screw 6, the soil sample is driven to rise in the extraction branch pipe 5. After the soil sample on the extraction screw 6 comes into contact with the protrusion, the soil sample is transferred to the slope seat 19. The soil sample is discharged using the inclined discharge trough 20. After the extraction cylinder seat 4 is removed from the water body, the soil sample is removed from the extraction cylinder seat 4, and then the presence of pollutants in the soil sample is detected.

[0041] During the longitudinal movement of the extraction cylinder seat 4, the second electric cylinder 29 is activated to drive the connecting ring 28 to slide on the slide groove 13, causing multiple traction belts 30 to move together with the connecting ring 28. Since the lengths of the different traction belts 30 are not the same, the traction belts 30 under force pull the counterweight seat 27 to move within the extension cylinder seat 26, causing the counterweight seat 27 to drive the plunger rod 24 to move out of the water sample collection cylinder 7, generating a negative pressure suction force in the water sample collection cylinder 7, attracting the water in the water layer into the water sample collection cylinder 7. After the extraction cylinder seat 4 is removed from the water body, the counterweight seat 27 is manually pushed down, and then the water sample in the water sample collection cylinder 7 is discharged for water sample testing.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
