Abstract

[0034] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.
[0035] Embodiment 1
[0036] In order to solve the existing problems that the sampling of deep well groundwater and soil is generally carried out separately, the sampling efficiency is low, the cost and complexity of monitoring work are increased, and the changes of groundwater and soil are often interrelated, and separate sampling easily leads to the inability to capture changes in time, affecting the real-time and accuracy of monitoring, please refer to Figure 1-Figure 4The present invention provides an integrated sampling device for groundwater and soil in a deep well for groundwater monitoring in a semi-arid area, comprising a conveying mechanism 1, wherein the conveying mechanism 1 comprises a mounting frame 101 and two pulleys 102 rotatably arranged at two ends of the mounting frame 101, a belt 103 is wound between the two pulleys 102, and a first motor 104 for driving the pulley 102 to rotate is arranged on the top wide side surface of the mounting frame 101; a plurality of first clamping blocks 106 distributed at equal intervals are fixedly arranged on the belt 103, and an installation box 2 is clamped on the first clamping block 106, and a negative pressure sampling cylinder 3 for collecting groundwater and a soil sampling cylinder 4 for collecting soil on the inner wall of a deep well are respectively arranged in the installation box 2, and a clamping slot 203 for clamping the negative pressure sampling cylinder 3 and the soil sampling cylinder 4 is arranged in the inner cavity of the installation box 2, and the conveying mechanism 1 is used to transport the installation boxes 2 one by one to the bottom end for sampling.
[0037] A liquid level sensor 108 is fixedly provided on the wide side surface of the bottom end of the mounting frame 101, and the depth of the sampling device in the deep well is monitored by the liquid level sensor 108, so that water samples and soil samples at different depths can be accurately collected; a hook 105 is provided on the top of the mounting frame 101, and the hook 105 can be hung on the steel wire rope of the lifting device or other hanging parts, such as a hanging rod, etc., and the sampling device is lowered into the deep well by the lifting device, and the sampling device is made to be close to the inner wall of the deep well to facilitate soil sampling.
[0038] like Figure 3 As shown, a second clamping block 201 matching the first clamping block 106 is fixedly provided on the side of the installation box 2, and an elastic column 202 is provided on the second clamping block 201; the cooperation between the first clamping block 106 and the second clamping block 201 facilitates the installation and disassembly of the installation box 2.
[0039] like Figure 4-Figure 5As shown, a valve 301 is provided on the side of the negative pressure sampling cylinder 3, and an arc-shaped groove 302 is provided on the surface of the valve 301. A toggle rod 303 for opening and closing the valve 301 is provided in the arc-shaped groove 302; the inner end of the toggle rod 303 is provided with a toggle spring for resetting. The negative pressure sampling cylinder 3 is a cylinder that has been pumped with negative pressure. A vacuum pump or other vacuum equipment is used to pump out the air inside the cylinder, and a negative pressure environment is formed in the cylinder before sampling. When the cylinder is placed in the liquid to be sampled, the liquid will be automatically sucked into the cylinder due to the pressure difference between the inside and outside of the cylinder, thereby realizing automatic sampling without external force. When collecting water samples, the toggle rod 303 is moved to move along the arc-shaped groove 302, and the toggle rod 303 drives the valve core in the valve 301 to move, thereby opening the valve 301. Under the action of negative pressure, the water is sucked into the cylinder. The sample enters the negative pressure sampling tube 3 through the valve 301. When the pressure on the toggle rod 303 stops, the toggle rod 303 is reset under the restoring force of the torsion spring, the valve 301 is closed, and the collection of water samples stops. In practical applications, such as sampling at a depth of 5m underwater, the size of the valve 301 is set to 2cm×2cm. At this time, the water pressure on the valve 301 is about 20N. Therefore, it is necessary to ensure that the toggle rod 303 and the toggle member 5 have sufficient rigidity, and the torsion spring selected at the toggle rod 303 must have sufficient restoring force to restore to the original state.
[0040] like Figure 6 As shown, the direct push mechanism 6 includes a frame 603 fixed on the wide side of the bottom end of the mounting frame 101 and a second motor 604 fixed on the frame 603; a gear 605 is fixedly sleeved on the output shaft of the second motor 604, and a rack 401 meshing with the gear 605 is embedded and fixed on the surface of the soil sampling tube 4. When collecting soil samples, the second motor 604 is started, the second motor 604 drives the gear 605 to rotate, the gear 605 drives the rack 401 to move, and the rack 401 drives the soil sampling tube 4 to directly push deep into the soil to collect soil samples. Direct push sampling reduces the disturbance to the soil structure, ensures the original state and representativeness of the sample, and controls the second motor 604 to reverse, and resets the soil sampling tube 4.
[0041] Embodiment 2
[0042] On the basis of the first embodiment, in order to improve the convenience of opening and closing the negative pressure sampling cylinder 3 and the soil sampling cylinder 4, as shown in FIG. Figure 1-Figure 2 , Figure 4-Figure 5 As shown, a toggle member 5 for automatically opening the negative pressure sampling cylinder 3 and a direct push mechanism 6 for pushing the soil sampling cylinder 4 to the deep soil of the inner wall are respectively provided on the wide side surface at the bottom end of the mounting frame 101. When the negative pressure sampling cylinder 3 and the soil sampling cylinder 4 move to the lowest end along with the conveying mechanism 1, they contact the toggle member 5, and the negative pressure sampling cylinder 3 and the direct push mechanism 6 are automatically opened by the toggle member 5, thereby greatly improving the convenience of sampling.
[0043] In order to facilitate the personnel outside the deep well to conveniently and accurately control the operation of the conveying mechanism 1, the direct push mechanism 6 also includes a switch 601 fixed on the wide side of the bottom end of the mounting frame 101 and an indicator light 602 installed outside the monitoring deep well. The surface of the switch 601 is also provided with an arc groove 302, and a toggle rod 303 for opening and closing the switch 601 is also provided in the arc groove 302. The inner end of the toggle rod 303 is also provided with a torsion spring for resetting. The switch 601 is used to control the operation of the indicator light 602. When the negative pressure sampling cylinder 3 and the soil sampling cylinder 4 move to the lowest end with the conveying mechanism 1, they contact the toggle member 5, and the toggle member 5 drives the toggle rod 303 at the switch 601 to move along the arc groove 302, thereby turning on the switch 601. At this time, the indicator light 602 emits an indication light. The personnel outside the deep well judge that the negative pressure sampling cylinder 3 and the soil sampling cylinder 4 are just at the lowest end through the indication light, thereby controlling the conveying mechanism 1 to stop moving and controlling the direct push mechanism 6 to start collecting soil samples.
[0044] The shape of the toggle member 5 is set to be V-shaped, and the middle end of the toggle member 5 is rotatably arranged on the mounting frame 101 through a rotating shaft, and a torsion spring for resetting is arranged on the rotating shaft; one end of the toggle member 5 is used to toggle the toggle rod 303 of the negative pressure sampling cylinder 3, and the other end is used to toggle the toggle rod 303 of the switch 601. When the negative pressure sampling cylinder 3 and the soil sampling cylinder 4 move to the lowest end along with the conveying mechanism 1, they contact the toggle member 5, and the toggle member 5 drives the toggle rod 303 of the negative pressure sampling cylinder 3 and the toggle rod 303 of the switch 601 to move along their respective arc grooves 302, thereby opening the valve 301 and the switch 601.
[0045] Embodiment 3
[0046] On the basis of the first and second embodiments, in order to protect the integrity of the soil sample and avoid the problem that the soil sample is dispersed by the impact of water flow after collection, thereby affecting the monitoring accuracy, as shown in FIG. Figure 1-Figure 3 , Figure 7 , Fig. 9 As shown, magnet rings 204 with opposite magnetic properties are provided at both ends of the installation box 2. After sampling is completed, multiple installation boxes 2 are stacked together through the cooperation of the magnet rings 204. A magnetic top plate 7 for closing the topmost installation box 2 after sampling is completed is slidably provided on the narrow side surface of one side of the installation frame 101, and a slider 701 is fixedly provided at the end of the magnetic top plate 7. A sliding groove matching the slider 701 is provided on the narrow side surface of the installation frame 101, and the magnetic top plate 7 is magnetically connected to the magnet ring 204; a baffle 107 for automatically separating the first card block 106 and the second card block 201 is fixedly provided on the installation frame 101 located below the magnetic top plate 7.
[0047] When sampling is completed in the first installation box 2, the installation box 2 moves upward with the conveying mechanism 1. At this time, the opening of the soil sampling tube 4 is upward until the installation box 2 is attracted to the magnetic top plate 7, thereby closing the opening of the soil sampling tube 4 to prevent the soil sample from being dispersed by the impact of the water flow and affecting the accuracy of monitoring; when sampling is completed in the second installation box 2, the installation box 2 moves upward with the conveying mechanism 1. At this time, the first installation box 2 passes through the baffle 107 during the movement, and is separated from the first block 106 by the baffle 107. As the conveying mechanism 1 continues to run, the magnet ring 204 of the second installation box 2 is attracted to the magnet ring 204 of the first installation box 2, thereby closing the opening of the soil sampling tube 4 of the second installation box 2. In this way, multiple installation boxes 2 are stacked together to effectively protect the integrity of the soil sample.
[0048] In order to prevent the installation box 2 from falling due to gravity, Figure 8 As shown, a check assembly 8 for preventing the magnetic top plate 7 from sliding downward is also fixedly provided on the mounting frame 101; the check assembly 8 includes a mounting plate 801 fixed on the mounting frame 101, and a plurality of movable rods 802 movably penetrate the mounting plate 801 and are distributed at equal intervals. A second wedge block 804 matching the first wedge block 702 is fixedly provided at the end of the movable rod 802 close to the slider 701, and the first wedge block 702 is fixed on the side of the slider 701, and a spring 803 is sleeved on the other end of the movable rod 802. When the slider 701 moves upward, the inclined surface of the first wedge block 702 applies pressure to the inclined surface of the second wedge block 804, and the second wedge block 804 drives the movable rod 802 to move outward, and the spring 803 is compressed. After the first wedge block 702 moves to the top of the second wedge block 804, under the restoring force of the spring 803, the second wedge block 804 is reset to its original position, and the check assembly 8 does not affect the normal upward sliding of the slider 701; when the slider 701 tries to move downward, the plane of the first wedge block 702 contacts the plane of the second wedge block 804, and cannot apply pressure to the second wedge block 804, so that the second wedge block 804 can effectively prevent the slider 701 from moving downward.
[0049] The above-mentioned embodiment only expresses one implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
