Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring auxiliary equipment technology, and in particular to a soil groundwater sensor well installation and fixing device. Background Technology

[0002] Soil and groundwater monitoring is a crucial foundational element in environmental protection, water resource management, and geological engineering. By using sensors to collect key parameters such as water level, quality, and temperature in real time, it provides a scientific basis for pollution control, resource development, and disaster early warning. As the core monitoring equipment, sensors need to be stably installed underground to ensure the accuracy and long-term reliability of data acquisition.

[0003] Downhole environments are typically complex, with wellheads often having small diameters and large depths, narrow internal spaces, and potentially slippery, muddy, or unstable geological conditions. This places stringent requirements on sensor installation and fixation. Traditional installation methods often rely on operators directly entering the well. However, due to the limited diameter of the well and the confined operating space, personnel entering the well are not only inconvenient but also face safety risks such as oxygen deficiency, unstable well walls, or falls. Another common method is to use a float to attach the sensor to the well, suspending it in water through buoyancy. However, this method is inconvenient for sensor retrieval and maintenance, and the float is prone to breakage over prolonged use, causing instability in sensor deployment and affecting monitoring continuity. Summary of the Invention

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a soil groundwater sensor well installation and fixing device, comprising: an installation block, a take-up reel fixed to the top of the installation block, and a plurality of support rod mechanisms installed on the side of the installation block; the top of the take-up reel is provided with a through hole penetrating the installation block.

[0006] The strut mechanism includes: a flange mounted on the side of the mounting block, a rotating rod rotatably connected to one side of the flange, and a support cylinder sleeved on the side of the rotating rod; the support cylinder is fixed to the flange by a plurality of connecting columns, and a drive assembly for driving the rotating rod to rotate is provided on one side of the support cylinder;

[0007] A threaded rod is engaged with the side of the rotating rod, and a telescopic cylinder is engaged with the side of the support cylinder. One end of the threaded rod is rotatably connected to one end of the telescopic cylinder, and the inner side of the support cylinder near one end is threadedly connected to the side of the threaded rod. A support member for stable support is installed at one end of the telescopic cylinder.

[0008] In a preferred embodiment of this utility model, several of the support rod mechanisms are circumferentially distributed on the side of the mounting block in a uniform or non-uniform manner; the flange, rotating rod, support cylinder, threaded rod and telescopic cylinder are all coaxially arranged.

[0009] In a preferred embodiment of this utility model, the side of the rotating rod is engaged with the inner side of the threaded rod by a plurality of locking strips, and the side of the support cylinder is engaged with the inner side of the telescopic cylinder by a plurality of locking strips; the plurality of locking strips are circumferentially distributed in a uniform or non-uniform manner.

[0010] In a preferred embodiment of the present invention, the driving assembly includes: a rotating ring rotatably connected to the side of the support cylinder near the flange, an internal gear fixed inside the rotating ring, and a driven gear fixed to the side of the rotating rod; a plurality of transmission gears mesh between the internal gear and the driven gear, and one side of the transmission gear is rotatably connected to one end of the support cylinder.

[0011] In a preferred embodiment of this utility model, the rotating ring is coaxially arranged with the support cylinder, and the side of the rotating ring is provided with a plurality of anti-slip grooves.

[0012] In a preferred embodiment of the present invention, the support member includes: a hinge block fixed to one end of the telescopic cylinder, and a support piece hinged to one side of the hinge block.

[0013] In a preferred embodiment of the present invention, the side of the support piece facing away from the telescopic cylinder includes a flexible layer.

[0014] In a preferred embodiment of this invention, the surface of the flexible layer is provided with anti-slip texture.

[0015] In a preferred embodiment of this utility model, a handle is fixed to the top of the mounting block.

[0016] In a preferred embodiment of this utility model, the side of the flange is fixed to one side of the mounting block by bolts.

[0017] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0018] (1) This utility model provides a soil groundwater sensor well installation and fixing device. Through the adjustable distribution design of the strut mechanism, the device can be arranged uniformly or non-uniformly in the circumferential direction according to the actual situation of the well wall. It allows for balanced support force in regular well walls and flexible adjustment of the support point position in non-standard well conditions with obstacles. This improves the device's adaptability to complex well environments and ensures stable fixing under various well shapes. The fixing device is easy to operate and can achieve rapid installation and stable fixing. It can also flexibly adapt to different well opening sizes, thereby effectively solving the problems of high operation risk, inconvenient loading and unloading, and insufficient stability in traditional methods.

[0019] (2) In this utility model, a gear transmission drive assembly is adopted. The operator can manually rotate the rotating ring to transmit torque through the gear set, drive the rotating rod to rotate and drive the threaded rod to extend and retract, which can achieve the effect of deceleration and torque increase. The operation process is labor-saving and efficient, without the need for additional tools or strong operation, thereby reducing the risk of operation error, enabling a single person to complete the installation and fixation, and improving work efficiency.

[0020] (3) In this utility model, the back of the support plate of the support member is provided with a flexible layer and the surface has anti-slip texture. When the telescopic cylinder extends, the support plate is adaptively deflected through the hinge block. At the same time, the flexible layer undergoes elastic deformation and comes into close contact with the well wall. The anti-slip texture on the surface increases the friction, thereby enabling the support plate to fit the irregular well wall surface and avoid the squeezing damage to the well wall caused by rigid contact. This enhances the friction between the device and the well wall, provides a more solid support foundation, and extends the service life of the device. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0028] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] It should be noted that the soil and groundwater sensor well installation and fixing device of this application is applicable to groundwater sensors with wired connections, including but not limited to wired COD turbidity sensor of model MDS-COD09X, wired static pressure sensor of model OHR-L2Y and wired groundwater level sensor of model HG TP008.

[0030] like Figure 1 As shown, a soil and groundwater sensor well mounting and fixing device includes: a mounting block 1, a take-up reel 2 fixed to the top of the mounting block 1, and several support rod mechanisms 3 installed on the side of the mounting block 1; the top of the take-up reel 2 has a through hole 21 that penetrates the mounting block 1; the support rod mechanism 3 includes: a flange 31 installed on the side of the mounting block 1, a rotating rod 32 rotatably connected to one side of the flange 31, and a support cylinder 33 sleeved on the side of the rotating rod 32; the support cylinder 33 is fixed to the flange 31 by several connecting columns 34, and a drive assembly for driving the rotating rod 32 to rotate is provided on one side of the support cylinder 33; a threaded rod 35 is snapped onto the side of the rotating rod 32, and a telescopic cylinder 36 is snapped onto the side of the support cylinder 33; one end of the threaded rod 35 is rotatably connected to one end of the telescopic cylinder 36, and the inner side of the support cylinder 33 near one end is threadedly connected to the side of the threaded rod 35; a support member for stable support is installed at one end of the telescopic cylinder 36.

[0031] It should be noted that several strut mechanisms 3 are circumferentially distributed on the side of the mounting block 1 in a uniform or non-uniform manner. The uniform circumferential distribution is suitable for standard wells with regular and circular well walls, and can provide balanced support force. The non-uniform distribution is specifically for non-standard wells with obstacles such as local protrusions, depressions or pipes on the well wall. By adjusting the angle distribution of the strut mechanisms 3, obstacles can be avoided and suitable support points can be found, which greatly enhances the environmental adaptability of the device. The flange 31, rotating rod 32, support cylinder 33, threaded rod 35 and telescopic cylinder 36 are all coaxially arranged. The side of the flange 31 is fixed to one side of the mounting block 1 by bolts. The diameter of the wire hole 21 is preferably 5-20 mm. The inner wall is provided with a rubber gasket to prevent cable wear. The edge of the take-up reel 2 is provided with an elastic buckle for temporarily fixing the end of the wound cable.

[0032] Specifically, the sensor cable is passed through the cable reel 2's cable hole 21, and the entire device is placed into the wellhead. The rotating rod 32 is driven to rotate using the drive components of multiple support rod mechanisms 3. Since the threaded rod 35 is engaged with the rotating rod 32, they can rotate synchronously. The threaded connection between the support cylinder 33 and the threaded rod 35 allows the threaded rod 35 to translate axially along the rotating rod 32 while rotating. Simultaneously, since one end of the threaded rod 35 is rotatably connected to the telescopic cylinder 36, and the telescopic cylinder 36 is engaged with the side of the support cylinder 33, the telescopic cylinder 36 can move synchronously with the threaded rod 35. This allows the telescopic cylinder 36 to extend and contact the well wall through the support members, resulting in multiple support members forming multi-point contact with the well wall. When evenly distributed, the force on each support rod is balanced. The sensor is then lowered into the groundwater via the cable harness, and the excess cable is wound around the cable reel 2 to complete the installation. This fixing device is convenient to operate, allows for rapid installation and stable fixation, and can flexibly adapt to different wellhead sizes, effectively solving the problems of high operational risk, inconvenient placement and removal, and insufficient stability in traditional methods.

[0033] As a preferred operating method, the number of strut mechanisms 3 is preferably three, and they are evenly distributed circumferentially on the side of the mounting block 1 at an included angle of 120°. When using three strut mechanisms 3 for multi-point support, two of the strut mechanisms 3 can be used first to drive the telescopic cylinder 36 to extend as far as possible to contact the well wall, and then the telescopic cylinder 36 of the remaining strut mechanism 3 can be driven to extend adaptively to contact the well wall. This allows for a larger operating space at the included angle between the telescopic cylinders 36 of the two strut mechanisms 3, which is convenient for the daily operation of water pipes and other equipment when the wellhead is in use.

[0034] In some embodiments, the side of the rotating rod 32 is engaged with the inner side of the threaded rod 35 by a plurality of locking strips 4, and the side of the support cylinder 33 is engaged with the inner side of the telescopic cylinder 36 by a plurality of locking strips 4; the plurality of locking strips 4 are circumferentially distributed in a uniform or non-uniform manner.

[0035] It should be noted that the locking strip 4 has a rectangular or trapezoidal cross section, which forms an interference fit with the locking groove on the inner side of the threaded rod 35 / telescopic cylinder 36 to ensure lossless transmission of rotational torque.

[0036] Specifically, when the rotating rod 32 rotates, the retaining strip 4 on its side drives the threaded rod 35, which is engaged with it, to rotate synchronously. The support cylinder 33 restricts the circumferential rotation of the telescopic cylinder 36 through the retaining strip 4. When the threaded rod 35 moves axially under the drive of the internal thread of the support cylinder 33, the telescopic cylinder 36 only extends and retracts axially due to the retaining constraint, avoiding the offset of the support component caused by rotation. The uniform distribution of the retaining strips 4 makes the force transmission smoother, while the non-uniform distribution can increase the number of retaining strips 4 in areas with greater force, thereby improving the connection strength and achieving decoupling of rotation and extension.

[0037] In some embodiments, the drive assembly includes: a rotating ring 5 rotatably connected to the side of the support cylinder 33 near the flange 31, an internal gear 51 fixed inside the rotating ring 5, and a driven gear 52 fixed to the side of the rotating rod 32; a plurality of transmission gears 53 mesh between the internal gear 51 and the driven gear 52, and one side of the transmission gear 53 is rotatably connected to one end of the support cylinder 33.

[0038] It should be noted that the rotating ring 5 is coaxially arranged with the support cylinder 33, and several anti-slip grooves are provided on the side of the rotating ring 5; the internal gear 51, the driven gear 52 and the transmission gear 53 are located on the side of the flange 31, forming a relatively closed cavity with the support cylinder 33 and the rotating ring 5, and are coated with long-lasting grease. At the same time, a sealing ring is provided at the connection between the rotating ring 5 and the support cylinder 33 to prevent mud and water from entering.

[0039] Specifically, by manually rotating the rotating ring 5 with anti-slip grooves, the internal gear 51 inside it can be rotated. The internal gear 51 drives several transmission gears 53 that mesh with it, and the transmission gears 53 then transmit the power to the driven gear 52 fixed on the rotating rod 32. Since the rotating ring 5 is coaxial with the support cylinder 33, no eccentric torque is generated during the rotation, and the rotation of the rotating rod 32 is finally realized. The gear transmission achieves the effect of deceleration and torque increase, so that the operator does not need to apply too much force to drive the threaded rod 35 to extend and retract, thereby reducing the intensity of wellhead operation.

[0040] In some embodiments, the support includes: a hinge block 6 fixed to one end of the telescopic cylinder 36, and a support piece 61 hinged to one side of the hinge block 6.

[0041] It should be noted that the side of the support plate 61 facing away from the telescopic cylinder 36 includes a flexible layer. The flexible layer is preferably made of highly elastic and corrosion-resistant materials such as rubber or engineering plastics. The surface of the flexible layer is provided with anti-slip textures, which are parallel or interlaced textures such as diamond or wave shapes, to significantly increase the static friction when in contact with the well wall.

[0042] Specifically, when the telescopic cylinder 36 extends outward until the support plate 61 contacts the well wall, under the action of pressure, the support plate 61 will undergo a slight adaptive angular deflection through the hinge block 6. At the same time, the flexible layer on its back will undergo elastic deformation and contact the well wall. The anti-slip texture further increases the coefficient of friction, allowing the support plate 61 to better fit the irregular well wall and disperse the concentrated stress. This not only protects the well wall structure from damage by rigid components but also provides a more stable support foundation.

[0043] In some embodiments, a handle 7 is fixed to the top of the mounting block 1; the gripping part of the handle 7 has an arc-shaped structure. During installation, the entire device is lowered to the wellhead by the handle 7. After the deployment of the sensor is completed, the device can be taken out by pulling the handle 7 upward after contacting the support of the strut mechanism 3, which facilitates the picking and putting of the device.

[0044] In use, the sensor cable is first threaded through the cable hole 21 of the take-up reel 2. The entire device is then lowered to the wellhead using the handle 7. After the device is placed in the wellhead, the operator rotates the rotating ring 5 of the support rod mechanism 3, using the anti-slip grooves on its side to increase friction, which drives the inner gear 51 to rotate. The inner gear 51 drives the driven gear 52 to rotate through the transmission gear 53, thereby causing the rotating rod 32 to rotate synchronously. The retaining strip 4 on the side of the rotating rod 32 forms an interference fit with the threaded rod 35, causing the threaded rod 35 to rotate synchronously. Meanwhile, the support cylinder 33 restricts the circumferential rotation of the telescopic cylinder 36 through the retaining strip 4, causing the threaded rod 35 to translate axially under the action of the internal thread of the support cylinder 33, pushing the telescopic cylinder 36 to extend. The support plate 61 at the end of the telescopic cylinder 36 adaptively adjusts its angle through the hinge block 6. The flexible layer on its back undergoes elastic deformation and contacts the well wall through the anti-slip texture, forming a stable support. When using three strut mechanisms 3 evenly distributed at 120 degrees, first drive the telescopic cylinders 36 of two of the strut mechanisms 3 to extend as far as possible to contact the well wall, then adjust the third telescopic cylinder 36 to extend adaptively, leaving operating space between the two telescopic cylinders 36 for easy daily equipment operation at the wellhead. After the sensor is lowered into the groundwater via cable, the excess cable is wrapped around the take-up reel 2 and secured by the elastic clips on the edge, completing the installation. When it is necessary to remove the device, reverse the operation of the drive assembly to retract the telescopic cylinder 36 and detach it from the well wall, and then it can be removed as a whole by pulling it out using the handle 7.
