Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a sensor housing structure used for underground water level monitoring. Background Art

[0002] Groundwater level monitoring is helpful for understanding the distribution, reserves, recharge and discharge of groundwater resources. By monitoring the changes in groundwater levels, we can evaluate the sustainable utilization of groundwater resources and provide decision support for agricultural irrigation, industrial water use and domestic water use.

[0003] At present, in water level measurement, float type water level sensors can only measure the presence of water through switch quantity, although graded float type water level sensors can measure water levels at multiple depths; sensors for underground water level monitoring are used to monitor the water level status underground or in trenches. Since the sensor is equipped with a large number of electronic components, it is necessary to avoid liquid entering the device when working underwater to affect the measurement accuracy;

[0004] Therefore, a sensor housing structure for underground water level monitoring is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a sensor housing structure for underground water level monitoring in order to solve the above-mentioned problem, thereby improving the problem that the sensor is equipped with a large number of electronic components and liquid needs to be prevented from entering the device when working underwater, thereby affecting the measurement accuracy.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions. A sensor housing structure for underground water level monitoring includes: an upper shell body, two connecting buckles are fixedly connected to both sides of the upper shell body; a measuring mechanism, the measuring mechanism is installed on the surface of the upper shell body, and the surface of the measuring mechanism extends to the interior of the upper shell body; wherein, the measuring mechanism includes a sealing shell assembly arranged below the upper shell body, the surface of the sealing shell assembly extends to the interior of the upper shell body, and a measuring shell assembly is arranged on the upper end of the sealing shell assembly, and the measuring shell assembly is installed on the surface of the upper shell body.

[0007] Preferably, the sealing shell assembly includes a lower shell plate installed on the lower end of the upper shell body, the inner bottom wall of the lower shell plate is fixedly connected with a vertical clamping plate, the lower end of the upper shell body is provided with a lower groove, the inner wall of the upper shell body is provided with an annular groove, the inner top wall of the lower groove is provided with a placement groove, the inner wall of the placement groove is fixedly connected with an annular airbag, and the lower shell plate is installed on the lower end of the upper shell body, so that the lower shell plate forms a sealing effect when it moves upward.

[0008] Preferably, the measuring shell assembly includes a protective shell arranged at the upper end of the upper shell, a water-permeable hole is opened at the upper end of the protective shell, an inner cavity is opened at the upper end of the upper shell, the protective shell is fixedly connected to the inner wall of the inner cavity, and a built-in groove is opened inside the upper shell, the built-in groove is connected with the inner cavity, and liquid enters the inner cavity because the built-in groove is arranged at the lowest point of the inner cavity.

[0009] Preferably, the lower end of the annular airbag extends to the interior of the lower groove, and the lower end of the annular airbag contacts the upper end of the lower shell plate. The annular airbag follows the deformation inside the placement groove, forming the inner bottom wall of the annular airbag in contact with the inner top wall, forming a good sealing effect.

[0010] Preferably, a rubber cone ring is fixedly connected to the upper end of the lower shell plate, and the upper end of the rubber cone ring extends to the inside of the accommodating groove, and the rubber cone ring abuts against the annular airbag, so that the annular airbag is deformed.

[0011] Preferably, a rubber ring is fixedly connected to the surface of the vertical clamping plate, and the rubber ring is clamped with the inner wall of the adjacent ring groove. The cooperation between the rubber ring and the ring groove forms a multiple sealing effect, thereby achieving secondary sealing.

[0012] Preferably, a float is provided inside the built-in groove, and a support frame is fixedly connected to the inner wall of the built-in groove, which allows a gap to remain between the float and the bottom wall of the built-in groove, thereby preventing the lower end of the float from being adsorbed to the bottom wall of the built-in groove.

[0013] The beneficial effects of the utility model are:

[0014] 1. The sensor housing structure for underground water level monitoring can form a good sealing effect on the interior of the upper shell under the action of the sealing shell assembly. The device uses a rubber cone ring to resist the annular airbag, causing the annular airbag to deform and enhance the sealing effect. At the same time, a sealing effect is formed again under the action of the rubber ring and the ring groove, achieving a multiple sealing effect, thereby ensuring the accuracy of the measurement of electronic components inside the device.

[0015] 2. By setting up the measuring shell assembly, the floating ball can be assisted in supporting the floating ball under the action of the measuring shell assembly. When the floating ball moves from top to bottom, the water level height can be understood. The device can leave a gap under the floating ball through the configuration of the built-in groove and the supporting frame so that the floating ball will not be adsorbed, and the floating ball can slide smoothly and measure accurately.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] When implementing: Figure 1-4 As shown, a sensor housing structure for underground water level monitoring includes: an upper shell 1, two connecting buckles 2 are fixedly connected to both sides of the upper shell 1; a measuring mechanism 3, the measuring mechanism 3 is installed on the surface of the upper shell 1, and the surface of the measuring mechanism 3 extends to the interior of the upper shell 1; wherein the measuring mechanism 3 includes a sealing shell assembly 32 arranged below the upper shell 1, the surface of the sealing shell assembly 32 extends to the interior of the upper shell 1, and a measuring shell assembly 31 is arranged at the upper end of the sealing shell assembly 32, and the measuring shell assembly 31 is installed on the surface of the upper shell 1;

[0023] like Figure 1 , Figure 2 and Figure 4As shown, the sealing shell assembly 32 includes a lower shell plate 321 installed on the lower end of the upper shell 1, the inner bottom wall of the lower shell plate 321 is fixedly connected with a vertical clamping plate 322, the lower end of the upper shell 1 is provided with a lower groove 323, the inner wall of the upper shell 1 is provided with an annular groove 326, the inner top wall of the lower groove 323 is provided with a placement groove 324, the inner wall of the placement groove 324 is fixedly connected with an annular air bag 325, the lower end of the annular air bag 325 extends to the inside of the lower groove 323, the lower end of the annular air bag 325 contacts the upper end of the lower shell plate 321, the upper end of the lower shell plate 321 is fixedly connected with a rubber cone ring 328, the upper end of the rubber cone ring 328 extends to the inside of the placement groove 324, the surface of the vertical clamping plate 322 is fixedly connected with a rubber ring 327, and the rubber ring 327 is clamped with the inner wall of the adjacent annular groove 326;

[0024] When in use, the device can be installed at the lower end of the upper shell 1 through the lower shell plate 321. At this time, when the lower shell plate 321 moves upward, it drives the rubber cone ring 328 to move upward with it. At this time, the rubber cone ring 328 contacts the annular airbag 325, causing the annular airbag 325 to deform, and then the annular airbag 325 deforms inside the placement groove 324, forming a contact between the inner bottom wall and the inner top wall of the annular airbag 325, forming a good sealing effect, and when the annular airbag 325 is deformed, the annular airbag 325 will wrap the top tip of the rubber cone ring 328 to increase the sealing effect; at the same time, when the lower shell plate 321 moves upward, the device drives the vertical clamping plate 322 to extend into the interior of the upper shell 1. At this time, the cooperation between the rubber ring 327 and the annular groove 326 forms a multiple sealing effect, thereby achieving a secondary sealing effect;

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the measuring shell assembly 31 includes a protective shell 311 arranged at the upper end of the upper shell 1, a water-permeable hole 313 is provided at the upper end of the protective shell 311, an inner cavity 312 is provided at the upper end of the upper shell 1, the protective shell 311 is fixedly connected to the inner wall of the inner cavity 312, a built-in groove 315 is provided inside the upper shell 1, the built-in groove 315 is communicated with the inner cavity 312, a floating ball 314 is arranged inside the built-in groove 315, and a supporting frame 316 is fixedly connected to the inner wall of the built-in groove 315. When the liquid in the well is higher than the upper shell 1, the liquid enters the inner cavity 312 at this time. Since the built-in groove 315 is arranged at the lowest point of the inner cavity 312, the floating ball 314 gradually rises under the action of the buoyancy of the liquid at this time. The setting of the supporting frame 316 can keep a gap between the floating ball 314 and the inner bottom wall of the built-in groove 315, thereby avoiding the device from being adsorbed when entering the water and ensuring the stability of the measurement data of the device.

[0026] When the utility model is in use, the lower shell plate 321 is installed on the lower end of the upper shell body 1. At this time, when the lower shell plate 321 moves upward, it drives the rubber cone ring 328 to move upward with it. At this time, the rubber cone ring 328 contacts the annular airbag 325, and the annular airbag 325 is deformed. The annular airbag 325 follows the deformation inside the mounting groove 324, forming that the inner bottom wall of the annular airbag 325 contacts the inner top wall, and when the annular airbag 325 is deformed, it will wrap the top tip of the rubber cone ring 328 to increase the sealing effect; at the same time, when the lower shell plate 321 moves upward, the device drives the vertical clamping plate 322 to extend into the interior of the upper shell body 1. At this time, the cooperation between the rubber ring 327 and the annular groove 326 forms a multi-layer sealing effect, thereby achieving a secondary sealing effect.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
