Description

Technical Field

[0001] The utility model relates to the field of water level monitoring, in particular to an installation bracket for underground water level monitoring equipment. Background Art

[0002] Groundwater monitoring is an important means of evaluating the dynamics of water resources and the health of the ecological environment. The water level meter is the core equipment for monitoring groundwater levels. It determines the water level depth by measuring water pressure, mechanical displacement or sound wave reflection. In the process of groundwater monitoring, it is usually necessary to set up an instrument bracket at the observation hole and lower the water level meter and other instruments into the observation well, so that the water level in the observation hole can be automatically measured. This monitoring method can not only ensure the stability of the equipment, but also realize the continuous collection of data.

[0003] In the prior art, when using the bracket for installing groundwater level monitoring equipment, the cable of the water level meter is mostly fixed by simple binding or snap-on fixing. After long-term use, the cable of the water level meter is prone to loosening due to its own weight, water flow disturbance, etc. Once the cable is loose, it will cause the water level meter to sink and move, which may easily lead to distortion of monitoring data and reduce the accuracy of monitoring results. At the same time, during the process of retracting and releasing the cable of the water level meter, its outer wall will usually directly contact and rub against the installation bracket or the hole wall or hole mouth of the observation hole, which may easily cause the cable to wear or even break, shortening its service life. Utility Model Content

[0004] The purpose of the utility model is to overcome the defects of the prior art and provide an underground water level monitoring equipment installation bracket which can firmly limit the cable of the water level meter to improve the accuracy of the monitoring result and avoid the cable being worn and shortened in service life.

[0005] To achieve the above-mentioned purpose, the utility model provides an underground water level monitoring equipment installation bracket, which is arranged in an observation hole and used to install a water level meter, including a sleeve, a cover plate, a limit assembly and a waterproof joint. The two ends of the sleeve are open ends and are inserted into the observation hole. The cover plate is detachably installed on one end of the sleeve and is used to install the limit assembly, and the waterproof joint is arranged on the cover plate. The cable of the water level meter is wound around the limit assembly and is communicated with the external detection system through the waterproof joint.

[0006] Preferably, the limiting assembly comprises a lifting ring and a wire sleeve, the lifting ring is arranged on the cover plate, and the wire sleeve is sleeved on the cable of the water level gauge and is detachably connected to the lifting ring through a hanging rope.

[0007] Preferably, the limiting assembly comprises a locking column and a plurality of pulleys, the plurality of pulleys are arranged on the cover plate at intervals, the cables of the water level gauge are wound around the plurality of pulleys, and the locking column is detachably mounted on the cover plate and used to abut against the pulleys.

[0008] Preferably, one end of the lock column used for abutting against the pulley is provided with a flexible block, and the other end of the lock column passes through the cover plate and extends out of the sleeve and is provided with a turning handle.

[0009] Preferably, the limiting assembly includes a roller, a rotating shaft, a driving gear and a driven gear, the roller is rotatably mounted on the cover plate, the driven gear is provided at one end of the roller, the rotating shaft is rotatably mounted on the cover plate with limiting position, and the driving gear meshing with the driven gear is provided on the rotating shaft.

[0010] Preferably, a spiral groove for the cable of the water level gauge to extend into is formed on the outer wall of the drum, and annular protrusions are formed at the ends of both ends of the drum.

[0011] Preferably, a plurality of handles are arranged at intervals on the cover plate; and a plurality of water inlet holes are formed on the outer wall of the bottom of the sleeve.

[0012] Beneficial effects:

[0013] 1. In the installation bracket of the underground water level monitoring equipment of the utility model, the cable of the water level meter can be tightened by the coordinated use of the limit assembly and the waterproof joint to prevent the cable from loosening or relaxing on the limit assembly, thereby ensuring the stable installation of the water level meter, effectively preventing the water level meter from sinking and moving due to its own weight, water flow disturbance, etc., ensuring the accuracy of the water level meter monitoring data and reliable use.

[0014] 2. During the retraction and extension process of the water level meter of the mounting bracket for underground water level monitoring equipment of the utility model, since the cable of the water level meter is wound on the limit assembly, no pressure is applied to the interface edge of the waterproof connector. This can prevent the cable of the water level meter from being worn or broken due to the friction of the waterproof connector, thereby not only improving the durability of the cable of the water level meter, but also extending its service life.

[0015] 3. In the installation bracket of the underground water level monitoring device of the utility model, by winding the cable of the water level meter on the limit assembly, when the cable swings, the cable can bend and continue to be wound on the limit assembly, thereby eliminating the stress concentration of the cable of the water level meter at the swing point, avoiding the cable from being subjected to lateral shear force at the swing point, and further improving the durability of the cable, making the utility model suitable for monitoring environments with turbulent water flow or frequent vibration.

[0031] Embodiment 1:

[0032] The utility model provides a mounting bracket for underground water level monitoring equipment.

[0033] In one embodiment of the utility model, the mounting bracket of the groundwater level monitoring equipment is arranged in the observation hole and is used to install the water level meter 1, including a sleeve 2, a cover plate 3, a limit assembly and a waterproof joint 4. The two ends of the sleeve 2 are open ends and are inserted into the observation hole. The cover plate 3 is detachably mounted on one end of the sleeve 2 and is used to install the limit assembly, and a waterproof joint 4 is arranged on the cover plate 3. The cable of the water level meter 1 is wound around the limit assembly and is communicated with the external detection system through the waterproof joint 4.

[0034] Working principle: When it is necessary to monitor the groundwater status at a preset position, the staff can open an observation hole at the preset position so that the casing 2 can be inserted into the observation hole. Since both ends of the casing 2 are open ends, the groundwater can directly flow into the casing 2 to meet the monitoring needs of the water level meter 1. After the casing 2 is installed, the staff can lower the water level meter 1 to the bottom of the casing 2 and wind the cable of the water level meter 1 around the limit assembly. At the same time, the cable of the water level meter 1 is connected to the external detection system through the waterproof connector 4 on the cover plate 3. In this way, the installation and fixation of the water level meter 1 can be completed, and the groundwater can be monitored in real time through the water level meter 1.

[0035] Specifically, Figures 1 to 6 As shown, in the mounting bracket of the underground water level monitoring device of the utility model, since both ends of the casing 2 are open ends, when the casing 2 is inserted into the observation hole, the groundwater can directly flow into the casing 2 to meet the monitoring requirements of the water level meter 1, and the structural design is simple and reasonable. When the water level meter 1 needs to be installed, since a limit assembly is provided on the cover plate 3, the limit assembly can be a hook, etc., that is, by winding the cable of the water level meter 1 in a multi-turn manner around the limit assembly and can be reinforced by a binding wire, so that the water level meter 1 can be firmly mounted on the limit assembly, and the limit assembly bears the downward pulling force from the water level meter 1; at the same time, the staff passes the cable of the water level meter 1 through the waterproof connector 4, and the cable of the water level meter 1 can be tightened through the waterproof connector 4 to prevent the cable from being loosened or relaxed on the limit assembly, thereby ensuring the stable installation of the water level meter 1, effectively preventing the water level meter 1 from sinking and moving due to its own weight, water flow disturbance, etc., ensuring the accuracy of the monitoring data of the water level meter 1 and reliable use.

[0036] It can be understood that during the process of retracting and releasing the water level meter 1, since its cable is wound on the limit assembly, no pressure is applied to the interface edge of the waterproof connector 4, thereby preventing the cable of the water level meter 1 from being worn or broken by the friction of the waterproof connector 4, thereby not only improving the durability of the cable of the water level meter 1, but also extending its service life. In addition, since groundwater flow or external vibration can cause the water level meter 1 to shake, when the water level meter 1 shakes, such as Figure 7As shown, at this time, the cable of the water level meter 1 will swing synchronously. When the cable swings, the mounting bracket in the prior art will generate stress concentration at the swing point of the cable (i.e., at the interface edge of the waterproof joint 4) and apply lateral shear force to the cable, thereby making the cable of the water level meter 1 easily worn at the swing point and sheared and broken. In the mounting bracket of the underground water level monitoring device of the utility model, by winding the cable of the water level meter 1 on the limit assembly, when the cable swings, the cable can bend and continue to be wound on the limit assembly, thereby eliminating the stress concentration of the cable of the water level meter 1 at the swing point, avoiding the cable from being subjected to lateral shear force at the swing point, further improving the durability of the cable, and making the utility model suitable for monitoring environments with turbulent water flow or frequent vibration.

[0037] In one embodiment, specifically, Figure 1 As shown, the limit assembly includes a lifting ring 5 and a wire sleeve 6. The lifting ring 5 is arranged on the cover plate 3. The wire sleeve 6 is sleeved on the cable of the water level meter 1 and is detachably connected to the lifting ring 5 through a hanging rope, so that the water level meter 1 can be stably mounted on the lifting ring 5. At this time, the lifting ring 5 and the hanging rope bear the downward pulling force from the water level meter 1, so as to ensure the installation stability of the water level meter 1, avoid the water level meter 1 from sinking and moving due to water flow impact or external vibration, ensure the accuracy and reliability of the monitoring results, and the structural design is simple and reasonable. When the water level meter 1 is shaken by the impact of water flow, the flexible connection structure formed by the wire sleeve 6 and the hanging rope can convert the lateral shear force generated by the swing of the water level meter 1 and the cable into a tensile force on the hanging rope, and the wire sleeve 6 can increase the structural strength of the cable, thereby avoiding the risk of the cable being easily broken due to shear wear during swinging, and extending the service life of the cable of the water level meter 1.

[0038] In another embodiment, the limit assembly includes a locking column 7 and a plurality of pulleys 8, the plurality of pulleys 8 are arranged on the cover plate 3 at intervals, the cables of the water level meter 1 are wound around the plurality of pulleys 8, and the locking column 7 is detachably mounted on the cover plate 3 and is used to abut against the pulleys 8. Specifically, Figure 3 and Figure 4As shown, by winding the cable of the water level gauge 1 around a number of pulleys 8, the pulleys 8 bear the downward pulling force from the water level gauge 1. When the water level gauge 1 shakes, the cable of the water level gauge 1 continues to be wound along the circumference of the pulleys 8, thereby eliminating the stress concentration of the cable of the water level gauge 1 at the swing point, avoiding the cable from being subjected to lateral shear force at the swing point, extending the service life of the cable of the water level gauge 1, and the structural design is simple and reasonable. It can be understood that since the lock column 7 is detachably installed on the cover plate 3, the lock column 7 and the cover plate 3 can be detachably installed in a threaded connection. When the water level gauge 1 is lowered into place, the staff can screw the lock column 7 to make it abut against the pulley 8, thereby preventing the pulley 8 from rotating arbitrarily and causing the water level gauge 1 to sink and move, ensuring the installation stability of the water level gauge 1 and ensuring the accuracy of the monitoring results.

[0039] In one embodiment, a flexible block is provided at one end of the lock column 7 for contacting with the pulley 8, and the other end of the lock column 7 extends through the cover plate 3 to the outside of the sleeve 2 and is provided with a turning handle. Figure 3 and Figure 4 As shown, the flexible block can be a rubber block or a silicone block, etc., and the flexible block replaces the lock column 7 to abut against the pulley 8, which can improve the friction limiting effect of the lock column 7 on the pulley 8, and greatly improve the installation stability of the water level meter 1. In addition, by providing a turning handle at the end of the lock column 7 extending outside the sleeve 2, it is convenient for the staff to turn the lock column 7, which is convenient for operation, simple and convenient to use.

[0040] In another embodiment, the limiting assembly includes a roller 9, a rotating shaft 10, a driving gear 11 and a driven gear 12. The roller 9 is rotatably mounted on the cover plate 3, one end of the roller 9 is provided with the driven gear 12, the rotating shaft 10 is rotatably mounted on the cover plate 3, and the driving gear 11 meshing with the driven gear 12 is provided on the rotating shaft 10. Specifically, as Figure 5 and Figure 6 As shown, by winding the cable of the water level gauge 1 on the outer wall of the drum 9, the drum 9 is subjected to the downward pulling force from the water level gauge 1. When the water level gauge 1 shakes, the cable of the water level gauge 1 continues to be wound along the outer wall of the drum 9, thereby eliminating the stress concentration of the cable of the water level gauge 1 at the swing point, avoiding the cable from being subjected to lateral shear force at the swing point, and extending the service life of the cable of the water level gauge 1.

[0041] Understandably, if Figure 6As shown, since a driven gear 12 is provided at one end of the drum 9, a rotating shaft 10 is installed on the cover plate 3 in a limited rotation manner, and a driving gear 11 meshing with the driven gear 12 is provided on the rotating shaft 10, so that the staff can rotate the drum 9 synchronously by rotating the rotating shaft 10, and then can retract and release the cable of the water level gauge 1 and thereby fine-tune the installation height of the water level gauge 1, which is flexible and convenient to use. In addition, the limited rotation mode of the rotating shaft 10 and the cover plate 3 can be adopted as a pin-shaft clamping, that is, when the rotating shaft 10 does not need to be rotated, the staff can use the pin to clamp the rotating shaft 10 so that it cannot rotate relative to the cover plate 3. The structural design is simple and reasonable. At the same time, under the action of the mutually meshing driving gear 11 and the driven gear 12, the drum 9 can be prevented from rotating arbitrarily relative to the rotating shaft 10 or the cover plate 3, that is, the locking and limiting of the tank body is realized, thereby preventing the water level gauge 1 from sinking and moving, ensuring the installation stability of the water level gauge 1, ensuring the accuracy of the monitoring results, and reliable use.

[0042] In one embodiment, a spiral groove for the cable of the water level meter 1 to extend into is formed on the outer wall of the drum 9, and an annular protrusion 13 is formed at the ends of both ends of the drum 9. Figure 5 and Figure 6 As shown, a continuous cable guide channel can be formed on the drum 9 through the spiral groove, so that the cable of the water level gauge 1 can be evenly wound on the drum 9, thereby effectively avoiding surface damage caused by mutual squeezing or friction of the cable. In addition, the annular protrusion 13 can ensure that the cable is always within the predetermined winding range on the drum 9, preventing the cable from slipping and shifting during the rotation of the drum 9, etc., and ensuring the hanging support effect of the drum 9 on the water level gauge 1.

[0043] In one embodiment, a plurality of handles 14 are provided at intervals on the cover plate 3; and a plurality of water inlet holes are formed on the outer wall at the bottom of the sleeve 2. Figure 1 and Figure 2 As shown, the plurality of handles 14 enable the staff to apply force at multiple angles during the disassembly and assembly of the cover plate 3, thereby facilitating the staff to disassemble and assemble the cover plate 3 and facilitating the picking and carrying of the cover plate 3. In addition, it can be understood that the plurality of water inlet holes can increase the water inlet effect of the casing 2, effectively avoiding the problem of water level monitoring delay caused by poor water inlet of the casing 2, thereby ensuring the real-time and accuracy of the monitoring data of the water level meter 1.

[0044] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
