Description

Technical Field

[0001] This application relates to the field of monitoring well sampling equipment technology, and in particular to a groundwater monitoring well sampling device. Background Technology

[0002] In groundwater monitoring well sampling operations, the efficient and stable operation of the sampling device is crucial. Currently, although there are various groundwater monitoring well sampling devices on the market, and some progress has been made in terms of functionality, for example, some devices can achieve stratified sampling to improve the accuracy of monitoring pollution in different aquifers, or reduce the volume of well washing before sampling and save sampling time through specific structural designs.

[0003] However, existing devices lack a structure for securing and locking the rope or wire rope winding mechanism. In actual operation, the rope or wire rope used for lowering and raising sampling components is typically fixed to a reel-like device using a simple winding method. When the device operates near the wellhead, the complex environment at the wellhead may present interference factors such as wind and vibration. Furthermore, during frequent lowering and raising of sampling components, this unsecured and unlocked winding method easily leads to the rope or wire rope loosening and slipping. Once the rope or wire rope slips, it not only affects the continuity of sampling operations and delays the monitoring progress, but in severe cases, it may cause the sampling component to fall deep into the monitoring well, damaging the equipment, increasing retrieval costs and time, and even potentially damaging the structure of the monitoring well itself. In addition, in scenarios requiring precise control of sampling depth, the inability to effectively secure and lock the rope winding mechanism makes it difficult to guarantee the consistency of the sampling depth each time, thus affecting the accuracy and comparability of the sampling data.

[0004] For related technology, please refer to Chinese Patent No. CN109095296A, which discloses a cable winding device for a stainless steel submersible pump. The device includes a support base, with four grounding nails welded to the four corners of the bottom of the support base. A support frame is welded to the upper part of the support base, and a rotating shaft is fixed to the top of the support frame via a bearing seat. A roller is fitted on the rotating shaft, and a crank handle is welded to the side wall of the roller away from the support frame. A spring is welded to the upper side wall of the support base, and a connecting plate is welded to the end of the spring away from the support base. A column is welded to the upper part of the connecting plate, and a cable drying device is welded to the end of the column away from the connecting plate. The cable drying device includes an outer shell and an inner liner cloth.

[0005] Although the management of long ropes was taken into consideration, it was only a simple winding device for winding up the ropes, which could not be reliably secured.

[0006] In response to the aforementioned technologies, a specially designed groundwater monitoring well sampling device is needed. This support can effectively and reliably fix ropes or wire ropes of different lengths and diameters during the placement of the sampling device. Utility Model Content

[0007] To improve the securing effect of ropes or wire ropes and ensure the safe and stable operation of the sampling device, this application provides a groundwater monitoring well sampling device.

[0008] This application provides a groundwater monitoring well sampling device, which adopts the following technical solution:

[0009] A groundwater monitoring well sampling device is characterized in that it includes a frame and a winding roller rotatably connected to the frame. One end of the winding roller extends along the axial direction by a preset length and is fixedly provided with a rotating handle. A locking device is provided between the frame and the rotating handle. At least one set of limiting components is provided on the side wall of the winding roller. The limiting components are arranged in a circle around the shaft of the winding roller.

[0010] By adopting the above technical solution, the operator rotates the handle, and after the wire rope is wound onto the winding roller, the operator locks the handle to the frame using a locking device to prevent the winding roller from rotating due to the weight of the unretracted wire rope. At the same time, the limiting components set on the side wall of the winding roller provide double fixation to prevent the winding roller from rotating, thus improving the stability of the device. By setting multiple sets of limiting components and distributing them circumferentially around the winding roller shaft, the limiting components can limit the winding roller when winding wire ropes of different lengths, thereby increasing the applicability of the device.

[0011] Optionally, the frame includes a U-shaped frame, on which a connecting seat is fixedly mounted. The connecting seat is rotatably connected to the rotating shaft of the take-up roller, and a baffle is provided between the connecting seat and the take-up roller.

[0012] By adopting the above technical solution and setting up a spiral frame, it is easy to install the device directly above the wellhead. By setting up baffles, the stability and safety of the device are improved.

[0013] Optionally, the lower end face of each of the four corners of the spiral frame is fixedly provided with a support leg, and the installation angle between the support leg and the spiral frame is greater than 90°, and a support frame is provided between the support legs.

[0014] By adopting the above technical solutions, the overall stability of the device is improved, the pressure on each support leg is distributed, and the service life of the device is increased.

[0015] Optionally, the bottom of the support leg is equipped with an adjustment mechanism for adjusting the angle and height of the support leg relative to the ground. The support leg has an L-shaped cross-section. The adjustment mechanism includes a base, and two sets of vertically placed and parallel limiting plates are fixedly provided on the upper surface of the base. The limiting plates have strip-shaped through holes, and the support leg has mounting holes at positions corresponding to the strip-shaped through holes. The limiting plates and the support leg are detachably connected by tightening bolts provided in the strip-shaped through holes.

[0016] By adopting the above technical solution, when the device is located on uneven ground, the positional relationship between the limit plate and the support leg can be adjusted by rotating and tightening the bolt, and then the rotating bolt can be tightened to achieve fine adjustment of the support and improve the applicability of the device.

[0017] Optionally, the limiting component is located on the side wall of the take-up roller away from the rotating handle. The limiting component includes a limiting block and a limiting rod. The limiting block has a through groove in the radial direction. The limiting rod is detachably inserted into the through groove. The limiting rod is made to abut against the frame by rotating the take-up roller.

[0018] By adopting the above technical solution, the operator inserts the limiting rod into the through groove of the limiting block so that when the winding roller rotates, the limiting rod and the bracket abut against each other, which restricts the further rotation of the rotating roller, improves the stability of the device, and at the same time balances the resistance on both sides of the winding roller, thus improving the stability of the device.

[0019] Optionally, the limiting rod is connected to the frame via a chain.

[0020] By adopting the above technical solution, it is easy to store the limit rod and prevent it from being lost.

[0021] Optionally, the locking device includes an iron ring fixed to the frame, and a locking ring is provided on the iron ring. The rotating handle is connected to the iron ring through the locking ring.

[0022] By adopting the above technical solution, the rotating handle is fixed to the frame by the locking ring, preventing the rotating handle from moving, thereby limiting the rotation of the take-up roller and improving the stability of the device.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting a locking device between the rotating handle and the frame, and setting a limiting component on the side wall of the winding roller, the winding roller is double-fixed, effectively preventing the winding roller from rotating and ensuring the safety and stability of the device during operation.

[0025] 2. The limiting components are distributed in a circle around the winding roller shaft, so that when the winding roller winds up wire rope or rope of different lengths, the limiting components can limit the winding roller, thus improving the applicability of the device.

[0026] 3. The spiral frame design facilitates the direct installation of the sampling device above the wellhead, and the adjustment mechanism at the bottom of the legs can adapt to different ground conditions, improving the versatility of the device.

[0027] 4. The rational design of the baffle between the connecting seat and the take-up roller, as well as other components, improves the stability and safety of the device. Meanwhile, the limit rod is connected to the frame via a chain, facilitating storage and preventing loss. Attached Figure Description

[0031] The present application will be further described in detail below with reference to all the accompanying drawings.

[0032] This application discloses a groundwater monitoring well sampling device.

[0033] Reference Figure 1 A groundwater monitoring well sampling device, characterized in that it includes a frame 1 and a winding roller 2 rotatably connected to the frame 1.

[0034] Reference Figure 1 One end of the winding roller 2 extends along the axial direction to a predetermined length and is fixedly equipped with a rotating handle 3. A locking device 4 is provided between the frame 1 and the rotating handle 3. At least one set of limiting components 5 are provided on the side wall of the winding roller 2. The limiting components 5 are arranged in a circle around the axis of the winding roller 2. When the operator rotates the rotating handle 3, after the wire rope is wound onto the winding roller 2, the operator locks the rotating handle 3 to the frame 1 through the locking device 4 to prevent the winding roller 2 from rotating due to the gravity of the unretracted wire rope. At the same time, the limiting components 5 on the side wall of the winding roller 2 provide double fixation to prevent the winding roller 2 from rotating, thereby improving the stability of the device. By setting multiple sets of limiting components 5 and distributing them in a circle around the axis of the winding roller 2, the limiting components 5 can limit the winding roller 2 when winding wire rope of different lengths, thus improving the applicability of the device.

[0035] Reference Figure 1 The frame 1 includes a U-shaped frame, on which a connecting seat 102 is fixedly mounted. The connecting seat 102 is rotatably connected to the rotating shaft of the winding roller 2. A baffle 103 is also provided between the connecting seat 102 and the winding roller 2. By setting the U-shaped frame, it is easy to install the device directly above the wellhead. By setting the baffle 103, the stability and safety of the device are improved. The lower end face of each of the four corners of the U-shaped frame is fixedly provided with a support leg 104, and the angle between the support leg 104 and the U-shaped frame is greater than 90°. A support frame 105 is provided between the support legs 104 to distribute the pressure on each support leg 104 and improve the overall service life of the device.

[0036] Reference Figure 1 The limiting component 5 is located on the side wall of the winding roller 2 away from the rotating handle 3. It balances the resistance on both sides of the winding roller 2 and improves the stability of the device. The limiting component 5 includes a limiting block 51 and a limiting rod 52. The limiting block 51 has a through groove 53 in the radial direction. The limiting rod 52 is detachably inserted into the through groove 53. The winding roller 2 rotates to make the limiting rod 52 abut against the frame 1. The operator inserts the limiting rod 52 into the through groove 53 of the limiting block 51 so that when the winding roller rotates, the limiting rod 52 abuts against the support, which limits the further rotation of the rotating roller and improves the stability of the device. The limiting rod 52 is connected to the frame 1 by an iron chain 54, which makes it easy to store the limiting rod 52 and prevents the limiting rod 52 from being lost.

[0037] Reference Figure 1 The locking device 4 includes an iron ring fixed on the frame 1, and a locking ring is also provided on the iron ring. The rotating handle 3 is connected to the iron ring through the locking ring. The locking ring fixes the rotating handle 3 to the frame 1, preventing the rotating handle 3 from moving, thereby limiting the rotation of the winding roller 2 and improving the stability of the device.

[0038] Reference Figure 2 The bottom of the support leg 104 is equipped with an adjustment mechanism 6 for adjusting the angle and height of the support leg 104 relative to the ground. The support leg 104 has an L-shaped cross-section. The adjustment mechanism 6 includes a base 61. Two sets of vertically placed and parallel limiting plates 62 are fixedly provided on the upper surface of the base 61. The limiting plates 62 have strip-shaped through holes 63. The support leg 104 has mounting holes at positions corresponding to the strip-shaped through holes 63. The limiting plates 62 and the support leg 104 are detachably connected by tightening bolts provided in the strip-shaped through holes 63. When the device is located on uneven ground, the tightening bolts are rotated to adjust the positional relationship between the limiting plates 62 and the support leg 104. Then, the rotating bolts are tightened to achieve fine-tuning of the support and improve the applicability of the device.

[0039] The implementation principle of the groundwater monitoring well sampling device in this application embodiment is as follows: The operator rotates the rotating handle 3 of the winding roller 2 to wind the steel wire rope. After completion, the locking device 4 locks the rotating handle 3 to prevent the winding roller 2 from rotating due to the weight of the steel wire rope. At the same time, the side wall limiting component 5 of the winding roller 2 makes the limiting rod 52 abut against the frame 1, thus doubly fixing the winding roller 2. Multiple sets of circumferentially distributed limiting components 5 are adapted to different steel wire rope lengths to realize the winding and fixing of the steel wire rope. The U-shaped frame facilitates the installation of the device above the wellhead. The connecting seat 102 allows the winding roller 2 to rotate. The baffle 103 in between improves stability. The frame legs 104 and the support frame 105 at the four corners of the frame share the pressure and extend the service life. If the ground is uneven, the bottom adjustment mechanism 6 of the frame legs 104 is adjusted. It consists of a base 61, a limiting plate 62 with a strip-shaped through hole 63 and tightening bolts. Rotating the bolts adjusts the position of the limiting plate 62 and the frame leg 104 to achieve fine adjustment of the bracket. The limiting rod 52 is connected to the frame body 1 by an iron chain 54 for easy storage and to prevent loss.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
