Description

Technical Field

[0001] This utility model relates to the technical field of seepage meter installation devices, and in particular to a well frame for installing seepage meters. Background Technology

[0002] When installing a percolator, for deep boreholes drilled on the ground, the probe needs to be suspended into the borehole and backfilled after reaching a suitable depth. Currently, manual suspension is the most common method. During the suspension process, the probe is prone to collision and friction with the inner wall of the borehole, causing external damage. Furthermore, during the backfilling stage after suspension, the personnel need to maintain a lifting motion for a long time, which is physically demanding and can easily cause the probe to tilt, making it impossible to guarantee a stable suspension state. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a well frame for installing a seepage meter, which addresses the above-mentioned technical deficiencies. By positioning the cable in the restricted space between two guide members, the cable can be guided, avoiding the traditional collision situation. Furthermore, by utilizing the clamping force between the guide members, the probe can be positioned after suspension, replacing manual lifting operations.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is a well frame for installing a seepage meter, characterized in that it includes: a support, a sleeve provided above the support, guide members symmetrically provided at the top of the sleeve, two guide members forming a restrictive space for guiding and limiting the cable, and the restrictive space opening and expanding after being subjected to force, and three legs arranged at equal angles installed below the support.

[0005] Preferably, the sleeve has symmetrical rectangular notches on the top; the guide includes a clamping plate and a telescopic member; the clamping plate is connected to the notch by a pivot, the inner end of the clamping plate is provided with a pressing wheel, and the outer end is connected to the outer wall of the sleeve through the telescopic member.

[0006] Preferably, the sleeve has an extension that can slide downward inside, and two sliding rods are symmetrically arranged below the extension, with a semi-ring sleeve at the inner end of the sliding rod.

[0007] Preferably, the semi-ring sleeve is provided with a magnetic attraction element.

[0008] Preferably, the outer wall of the extension is provided with locking screws.

[0009] Preferably, the slide bar has a contact surface on the side near the locking screw.

[0010] Preferably, the inner wall of the sleeve is provided with a groove, and the top of the extension is provided with a slider connected to the groove.

[0011] Preferably, the sleeve is provided with fixing screws for connection with the extension.

[0012] Preferably, the support leg includes a threaded rod and a support column fixedly connected to one end of the threaded rod, wherein the threaded rod and the support are threadedly connected.

[0013] Preferably, the bottom end of the support column is conical.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. After drilling, the device is placed at the borehole and adjusted so that the sleeve and the borehole are concentric. The permeameter probe is then passed through the confined space, and the confined space is used to guide and position the cable. During the cable release process, the probe enters the borehole vertically under the action of gravity. In the subsequent soil backfilling process, the clamping force generated by the guide and the metal wire tied to the cable can be used to position the probe height. The whole operation can be completed by a single person.

[0016] 2. Through the design of the extension piece and the assembly of the sliding rod, a second guide point can be formed, which improves the stability during the cable laying process. Furthermore, the sliding connection between the extension piece and the sleeve can be adjusted as needed to facilitate actual construction operations.

[0017] 3. The threaded rod and the bracket are connected by threads. After the bracket is placed, the support height can be adjusted as needed to achieve the leveling operation of the bracket. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0027] Specific implementation method one: Combining Figure 1-7 As shown, a well frame for installing a seepage meter includes: a support 1 and legs 2. A sleeve 3 is provided above the support 1. Guides 4 are symmetrically provided on the top of the sleeve 3. The two guides 4 form a limiting space 5 that can guide and limit the cable. The limiting space 5 expands its own space after being squeezed. Three legs 2 are installed below the support 1 at equal angles.

[0028] In use, after drilling with drilling equipment, the borehole is flushed. Then, the support 1 is placed at the borehole, and the sleeve 3 is initially adjusted to be concentric with the borehole. Then, the probe of the connecting cable can be inserted through the top of the sleeve 3, squeezed through the restricted space 5, and then guided by the guide 4 to clamp and guide the cable. The probe is adjusted to the bottom area of ​​the support 1 and close to the borehole entrance. Then, according to the suspension position, the support 1 is moved again to adjust the probe to the center area of ​​the borehole. Then, the cable is released and pushed downward to overcome the clamping force of the guide 4. The probe is suspended under its own weight. After reaching the specified depth, the clamping force can also be used to achieve height positioning. Then, backfilling is performed. The operation can be completed by a single person. During the backfilling process, the suspension stability is maintained, avoiding the shaking that occurs in traditional methods. Moreover, the guidance of the guide 4 also avoids the problem of the probe colliding with the inner wall of the borehole during suspension.

[0029] Preferred embodiments, in combination Figure 3As shown, the sleeve 3 has symmetrical rectangular notches 301 on its upper part; the guide 4 includes a clamping plate 401 and a telescopic member 402; the clamping plate 401 is connected to the notch 301 by a pivot, the inner end of the clamping plate 401 is provided with a pressing wheel 403, and the outer end is connected to the outer wall of the sleeve 3 through the telescopic member 402. After the two pressing wheels 403 come into contact, they form a limiting space 5 for cable positioning. The telescopic member 402 can be a tension spring structure. The tension of the tension spring is used to clamp the cable, and by wrapping and binding a metal wire around the cable, it forms a snap-fit ​​with the pressing wheel 403, which can realize the positioning of the probe during subsequent backfilling; in order to improve To ensure the stability of the clamping plate 401 after the high-pressure extrusion roller 403 contacts the cable, the telescopic component 402 adopts a threaded adjustment rod structure, which includes a first rod body with external threads machined on the outer wall, and a sleeve structure. The end of the sleeve has a rotatable nut structure, and the nut forms a threaded connection with the first rod body. The top of the first rod body is connected to the clamping plate 401 by a pivot, and the bottom of the sleeve is connected to the outer wall of the sleeve 3 by a pivot. By rotating the nut structure, the position of the clamping plate 401 can be manually adjusted, and the structure itself remains stable after adjustment. When it is necessary to clamp and fix the cable in the future, simply rotate the nut to continue tightening.

Below the extension 6, there are two sliding rods 7 that are symmetrically connected. The inner end of the sliding rod 7 is provided with a semi-ring 701. The two semi-rings 701 are spliced ​​together to guide and position the cable, increase the number of positioning points, and improve the stability during the cable laying process. The extension 6 is only slid out when in use, which also maintains the working condition of separating the probe from the cable.

[0031] Preferred embodiments, in combination Figure 6 As shown, a magnetic 702 is provided at the semi-ring 701, which uses magnetic force to achieve the connection after docking. Alternatively, a through hole can be machined at the magnetic 702, and an internal thread can be machined on the inner wall of the through hole, and a screw can be used for connection and fixation.

[0033] Preferred embodiments, in combination Figure 6 As shown, the slide bar 7 has a contact surface 703 on the side near the locking screw 601, which can increase the contact area with the end of the locking screw 601 and improve stability.

[0034] Preferred embodiments, in combination Figure 3 and Figure 5As shown, the inner wall of the sleeve 3 is provided with a sliding groove 302, and the top of the extension 6 is provided with a slider 602 connected to the sliding groove 302. The two are slidably connected to achieve the guiding and positioning of the extension 6. The sleeve 3 can pass through the top of the sliding groove 302 to facilitate the installation of the extension 6.

[0035] Preferred embodiments, in combination Figure 4 and Figure 5 As shown, the sleeve 3 is provided with a fixing screw 303 that is connected to the extension 6. The fixing screw 303 is inserted into the hole at the bottom of the extension 6 to fix the extension 6 in the stored state.
