Technical Field

[0001] The invention belongs to the technical field of groundwater collection, and relates to a groundwater collection device for geological engineering. Background Art

[0002] As one of the important water resources, groundwater is widely used in life and production, such as agricultural irrigation, industrial production, and residents' lives. Collecting groundwater samples is to understand the chemical composition and microbial indicators of groundwater, as well as to monitor whether groundwater is polluted and the degree of pollution, which is conducive to timely discovery and treatment of pollution sources and has great significance for protecting the safety and health of groundwater resources.

[0003] When collecting groundwater samples, it is often necessary to collect samples at different depths in order to understand the conditions of water at different depths. Current groundwater collection devices generally cannot simultaneously sample water at different depths in layers. When sampling water at different depths is required, multiple operations are required, which is not conducive to improving collection efficiency.

[0004] In order to solve the above problems, the present invention proposes a groundwater collection device for geological engineering. Summary of the invention

[0005] In order to solve the problems existing in the background technology, the present invention proposes a groundwater collection device for geological engineering.

[0006] In order to achieve the above-mentioned object, the technical solution adopted by the present invention is as follows: the groundwater collection device for geological engineering includes a support frame, a winding mechanism, a conveyor belt, a counterweight wheel and a sampling tube;

[0007] Two winding mechanisms are arranged on the support frame, and the two ends of the conveyor belt are arranged on the two winding mechanisms respectively; a weight wheel is arranged on the support mechanism for upward and downward movement, and the weight wheel cooperates with the first side of the conveyor belt, and the two ends of the conveyor belt are arranged on both sides of the weight wheel; there are multiple sampling tubes, which are sequentially connected to the second side of the conveyor belt, and the second side is away from the first side;

[0008] One end of the sampling tube is open, a piston plate is provided in the sampling tube in a sealing and sliding manner, and a hollow shell is fixedly connected to the side of the piston plate close to the opening end; a rectangular rod is provided in a sealing and sliding manner at the end of the sampling tube away from the opening, and the rectangular rod is fixedly connected to the piston plate; a one-way valve for allowing external water to flow in is provided at the end of the sampling tube away from the opening; a drainage assembly is provided on the end of the sampling tube away from the opening;

[0009] Initially, the open end of the sampling cylinder is facing downward, the hollow shell is located in the sampling cylinder, the right end of the conveyor belt is released, the counterweight wheel moves downward, the sampling cylinder moves from the right side to the left side of the conveyor belt to reach the sampling depth and turns over, and then under the action of buoyancy, the hollow shell pulls the piston plate upward, and water enters the sampling cylinder from the one-way valve.

[0010] Further, the sampling cylinder is arranged on the second side of the conveyor belt for upward and downward movement, and a driving assembly is arranged between each sampling cylinder and the conveyor belt;

[0011] The driving assembly includes a gear and a motor; an installation groove is opened on the outer wall of the sampling tube, and the motor is fixedly installed in the installation groove, and the gear is coaxially fixed on the motor shaft of the motor; a plurality of tooth grooves are opened on the second side surface of the conveyor belt, and the plurality of tooth grooves are distributed along the length direction of the conveyor belt; the gear is meshed with the tooth groove.

[0012] Furthermore, the drainage assembly includes a drain pipe and a valve; a drain pipe is installed at one end of the sampling tube away from the outlet, and the valve is installed on the drain pipe; when the sampling tube completes sampling, the valve is opened and the water in the sampling tube flows out through the drain pipe.

[0013] Furthermore, a first magnet is fixedly provided on the piston plate, and a second magnet cooperating with the first magnet is fixedly provided on the sampling tube.

[0014] Furthermore, a slide groove is provided on the conveyor belt, a slide rod is fixedly connected to the sampling tube, and the slide rod is slidably arranged in the slide groove.

[0016] Furthermore, one end of the rectangular rod away from the hollow shell extends out of the sampling tube and is fixedly connected with a baffle, which is opposite to the one-way valve. When the baffle abuts against the sampling tube, the baffle blocks the one-way valve.

[0017] Compared with the prior art, the present invention has the following beneficial effects: the winding mechanism on the right side performs the unwinding operation, the counterweight wheel moves downward, the conveyor belts on both sides of the counterweight wheel remain in a vertical state, and multiple sampling barrels enter the water in turn. Under the action of the buoyancy of the hollow shell, the piston plate abuts against the inner wall of the sampling barrel to prevent water from entering the sampling barrel through the one-way valve. Then the sampling barrel bypasses the counterweight wheel and moves to the left side of the conveyor belt and turns 180 degrees. The open end of the sampling barrel faces upward, and the sampling barrel reaches the sampling depth at this time. Under the buoyancy of the hollow shell, the piston plate moves upward, and water enters the sampling barrel through the one-way valve, thereby completing the sampling. Then, through the left and right winding mechanisms, the conveyor belt and the sampling barrel are moved upward to the ground as a whole, and then the water in the sampling barrel can be released through the drain pipe. With the unwinding operation of the second lifting rope, multiple sampling barrels reach the corresponding sampling depths in turn, and sample water at different depths, which is conducive to improving the collection efficiency.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0024] like Figure 1-Figure 3 As shown, the technical solution adopted by the present invention is as follows: a groundwater collection device for geological engineering, comprising a support frame, a winding mechanism, a conveyor belt 1, a counterweight wheel 4 and a sampling tube 9;

[0025] A telescopic rod 6 is fixedly mounted on the support frame. The telescopic rod 6 is vertically arranged. The lower end of the telescopic rod 6 is fixedly connected to a fixing frame 5. The counterweight wheel 4 is rotatably mounted on the fixing frame 5.

[0026] Two winding mechanisms are installed on the support frame. The two winding mechanisms are respectively arranged on the left and right sides of the counterweight wheel 4. The left end of the conveyor belt 1 is fixedly connected to the first lifting rope 2, and the first lifting rope 2 is wound on the winding mechanism on the left side thereof. The right end of the conveyor belt 1 is fixedly connected to the second lifting rope 3, and the second lifting rope 3 is wound on the right winding mechanism. The winding mechanism performs the line-reeling or line-releasing operation on the first lifting rope 2 or the second lifting rope 3. The support frame and the winding mechanism are both prior art and will not be described in detail here. The support mechanism and the winding mechanism are not drawn.

[0027] The conveyor belt 1 is passed around from the lower side of the counterweight wheel 4 and the first side of the conveyor belt 1 cooperates with the counterweight wheel 4. Under the action of the counterweight wheel 4, the conveyor belt 1 is in a stretched state.

[0028] The second side of the conveyor belt 1 faces away from the first side. A plurality of sampling barrels 9 are movably connected to the second side of the conveyor belt 1. A chute 8 is provided on the conveyor belt 1, and a slide bar 12 is fixed on the sampling barrel 9, and the slide bar 12 is slidably arranged in the chute 8. In this embodiment, there are two chute 8 and two slide bars 12, and the two slide bars 12 are arranged on both sides of the conveyor belt 1, and the slide bars 12 correspond to the chute 8 one by one. In this way, the sampling barrel 9 can be more stable.

[0029] A driving assembly is provided between the sampling barrel 9 and the conveyor belt 1 to enable the sampling barrel 9 to move up and down along the conveyor belt 1. The driving assembly includes a motor 10 and a gear 11. A plurality of tooth grooves 7 are provided on the second side surface of the conveyor belt 1, and the plurality of tooth grooves 7 are arranged along the length direction of the conveyor belt 1. An installation groove is provided on the outer side wall of the sampling barrel 9, and a motor 10 is fixedly installed in the installation groove. The gear 11 is coaxially fixedly connected to the motor shaft of the motor 10, and the gear 11 is meshed with the tooth groove 7. The motor 10 has a self-locking property, so that the sampling barrel 9 can be stably placed on the conveyor belt 1. When the motor 10 is started, the gear 11 rotates, and under the action of the tooth groove 7, the gear 11 moves up and down along the conveyor belt 1, thereby enabling the sampling barrel 9 to move up and down along the conveyor belt 1. In this way, the position of each sampling barrel 9 on the conveyor belt 1 can be adjusted, and the sampling depth of each sampling barrel 9 can be adjusted.

[0030] One end of the sampling barrel 9 is open and a hollow shell 14 is slidably provided at the open end of the sampling barrel 9. A piston plate 13 is sealed and slidably provided inside the sampling barrel 9, and one end of the piston plate 13 is fixedly connected to the hollow shell 14. A rectangular rod 15 is fixedly connected to the end of the piston plate 13 away from the hollow shell 14, and the end of the rectangular rod 15 away from the piston plate 13 slides through the sampling barrel 9 and extends to the outside of the sampling barrel 9, and the rectangular rod 15 is sealed and slidably matched with the sampling barrel 9. A baffle 16 is fixedly connected to the end of the rectangular rod 15 located outside the sampling barrel 9.

[0031] A first magnet 17 is fixedly connected to one end of the piston plate 13 away from the hollow shell 14 , and a second magnet 18 matching the first magnet 17 is fixedly connected to the sampling tube 9 . There is attraction between the first magnet 17 and the second magnet 18 .

[0032] A one-way valve 19 is installed on the end surface of the sampling tube 9 facing away from the outlet, and the outside water can flow into the sampling tube 9 through the one-way valve 19. The one-way valve 19 is opposite to the baffle 16. When the baffle 16 contacts the sampling tube 9, the baffle 16 blocks the one-way valve 19, thereby preventing the water in the sampling tube 9 from being accidentally contaminated after the sampling is completed.

[0033] A drainage assembly is installed on the end surface of the sampling cylinder 9 away from the outlet, avoiding the one-way valve 19. The drainage assembly includes a drainage pipe 20 and a valve 21. The drainage pipe 20 is installed at the end of the sampling cylinder 9 away from the outlet and is connected to the sampling cylinder 9. The valve 21 is installed on the drainage pipe 20. When the sampling cylinder 9 has finished sampling and needs to take the sample out of the sampling cylinder 9, the valve 21 is opened, and the water in the sampling cylinder 9 flows out through the drainage pipe 20.

[0034] Working principle:

[0035] Initially, the openings of the plurality of sampling tubes 9 face downward, and the plurality of sampling tubes 9 are all located on the right side of the counterweight wheel 4. The valve 21 is in a closed state. The first magnet 17 and the second magnet 18 are attracted to each other, and the hollow shell 14 is located in the sampling tube 9.

[0036] When it is necessary to adjust the spacing between adjacent sampling depths, the corresponding motor 10 is started, and the corresponding gear 11 rotates. Under the action of the tooth groove 7, the sampling cylinder 9 moves up and down along the conveyor belt 1, and the height of the sampling cylinder 9 is adjusted, thereby adjusting the spacing between the two corresponding sampling cylinders 9, so as to achieve the purpose of adjusting the spacing between adjacent sampling depths.

[0037] After the sampling depth of each sampling barrel 9 is adjusted, the device is moved to the position where sampling is required. The first lifting rope 2 and the second lifting rope 3 are both released, and the counterweight wheel 4, the conveyor belt 1 and the sampling barrel 9 move downward synchronously. The sampling barrel 9 is stationary relative to the counterweight wheel 4. When the left end of the conveyor belt 1 is flush with the set horizontal plane, the two winding mechanisms are closed.

[0038] After that, the winding mechanism on the right side is controlled to pay out the second lifting rope 3, while the winding mechanism on the left side remains closed, and the left end of the conveyor belt 1 is fixed. As the second lifting rope 3 is paid out, the right end of the conveyor belt 1 gradually moves downward, and the counterweight wheel 4 moves downward under the action of its own gravity, and the counterweight wheel 4 pulls the telescopic rod 6 to extend the telescopic rod 6. The right side of the conveyor belt 1 gradually moves to the left side of the conveyor belt 1, and both the left and right sides of the conveyor belt 1 remain in a vertical state.

[0039] As the conveyor belt 1 moves, the sampling barrel 9 gradually moves downward and multiple sampling barrels 9 gradually move downward from bottom to top, and the sampling barrel 9 gradually approaches the counterweight wheel 4. When the sampling barrel 9 gradually enters the water, the hollow shell 14 has a tendency to move upward under the action of buoyancy. Under the limit of the conveyor belt 1, the sampling barrel 9, the hollow shell 14 and the baffle 16 remain relatively still, and water cannot enter the sampling barrel 9 through the one-way valve 19. Then the sampling barrel 9 bypasses the counterweight wheel 4 and moves to the left side of the conveyor belt 1. At the same time, the sampling barrel 9 turns 180 degrees, so that the opening of the sampling barrel 9 is upward and the one-way valve 19 is downward. At this time, the sampling barrel 9 is at the sampling depth, and the sampling barrel 9 cannot move downward thereafter. Since the hollow shell 14 is upward and the one-way valve 19 is downward at this time, water enters the sampling barrel 9 through the one-way valve 19 under the action of water pressure. Under the action of buoyancy, the hollow shell 14 pulls the piston plate 13 so that the first magnet 17 overcomes the pressure of the second magnet 18 and gradually moves upward, and the water gradually enters the sampling tube 9 through the one-way valve 19. When the piston plate 13 moves to the open end of the sampling tube 9, the baffle 16 abuts against the sampling tube 9, so that the hollow shell 14 cannot continue to move upward. At this time, the sampling of the sampling tube 9 is completed. At this time, the baffle 16 blocks the one-way valve 19 to prevent the water in the sampling tube 9 from being contaminated. It should be noted that the setting of the hollow shell 14 must meet the following requirements: when the hollow shell 14 enters the water and the sampling tube 9 opens upward, under the action of buoyancy, the hollow shell 14 can pull the piston plate 13 so that the first magnet 17 overcomes the attraction of the second magnet 18 and moves upward. When the first magnet 17 and the second magnet 18 are attracted, there is no sealing contact between the piston plate 13 and the inner wall of the sampling tube 9 away from the opening end, so that when the sampling tube 9 is opened upward, water can smoothly pass through the one-way valve 19 into the sampling tube 9.

[0040] As the second lifting rope 3 unwinds, multiple sampling barrels 9 move to the left side of the conveyor belt 1 in sequence to reach the sampling depth, and the sampling is completed. When the sampling barrel 9 closest to the right end of the conveyor belt 1 moves to the left side of the conveyor belt 1 and reaches the sampling depth, the winding mechanism on the right side is closed.

[0041] When the sampling cylinders 9 have completed sampling and need to be taken out of the water, the two winding mechanisms are started at the same time, so that the first lifting rope 2 and the second lifting rope 3 are wound up at the same time, so that the conveyor belt 1 and the sampling cylinder 9 move upward as a whole, and the multiple sampling cylinders 9 are moved to the ground. At this time, the multiple sampling cylinders 9 are all on the left side of the conveyor belt 1 and the drain pipe 20 is facing downward, and the depth of the samples in the multiple sampling cylinders 9 from top to bottom is from shallow to deep, that is, the sample in the uppermost sampling cylinder 9 comes from the shallowest sampling depth, and the sample in the lowermost sampling cylinder 9 comes from the deepest sampling depth. Then open the valve 21 to release the sample in the sampling cylinder 9.

[0042] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
