Description

Technical Field

[0001] This utility model belongs to the field of water resources technology, specifically relating to a hydrological and water resources remote sensing terminal. Background Technology

[0002] Hydrological and water resources monitoring requires real-time data on water bodies such as rivers, lakes, and reservoirs, including parameters such as water level, flow rate, and water quality. Hydrological and water resources telemetry terminals are typically placed outdoors near water bodies. Therefore, the traditional method is to house these terminals in protective enclosures to protect them from rain. While some terminals have waterproof casings, the interfaces with the wiring are not waterproof or moisture-proof, necessitating placement within the enclosure. To ensure waterproofing and moisture protection, and to facilitate wiring within the enclosure, traditional protective enclosures are typically 1-3 times larger than the terminal itself, providing more space for waterproofing and better moisture protection. However, this design results in a bulky, unsightly, and space-consuming enclosure. Utility Model Content

[0003] To address the problems mentioned in the background section, this utility model provides a hydrological and water resources remote sensing terminal, which features a smaller overall protective size and an aesthetically pleasing appearance while being moisture-proof and waterproof.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a hydrological and water resources telemetry terminal, including a telemetry terminal housing with waterproof function, a wiring housing covering the terminal's plug-in end fixedly connected to the outside of the telemetry terminal housing, a clamping plate for squeezing a sealing ball installed on the inside of the wiring housing, and an electric wire passing through the clamping plate and the sealing ball to connect to the terminal.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-6 As shown:

[0028] A hydrological and water resources telemetry terminal includes a waterproof telemetry terminal housing 1. A wiring housing 3 covering the terminal's plug-in terminal is fixedly connected to the outside of the telemetry terminal housing 1. A clamping plate 4 for squeezing a sealing ball 5 is installed on the inside of the wiring housing 3. A wire 2 passes through the clamping plate 4 and the sealing ball 5 and is connected to the terminal.

[0029] The sealing ball 5 can be made of rubber. The sealing ball 5 is provided with a through hole 51 through which the power supply line 2 passes. The sealing ball 5 is also provided with a spiral slit 52 that communicates with the through hole 51, and the central axis of the spiral slit 52 coincides with the central axis of the through hole 51.

[0030] In this scheme, hydrological and water resources monitoring requires the acquisition of real-time data on water bodies such as rivers, lakes, and reservoirs, including parameters such as water level, flow rate, and water quality. Hydrological and water resources telemetry terminals are typically placed outdoors near water bodies. Therefore, the traditional method is to place the terminals in a protective enclosure for rain protection. While some terminals have waterproof casings, the interface with the power cable 2 is not waterproof or moisture-proof, necessitating placement in the enclosure. To ensure waterproofing and moisture protection, and to facilitate wiring within the enclosure, traditional protective enclosures are typically 1-3 times larger than the terminals themselves, providing more waterproof space and better moisture protection. However, this design results in a large, unsightly enclosure that occupies a significant amount of space.

[0031] This solution uses the clamping plate 4 to clamp the sealing ball 5, achieving a sealed connection between the sealing ball 5, the clamping plate 4, and the wire 2 under the cover of the wiring housing 3. This provides a good waterproof and moisture-proof sealing effect. Under the premise of being moisture-proof and waterproof, the overall protective volume is smaller and the appearance is more aesthetically pleasing.

[0032] The connection between the telemetry terminal housing 1 and the wiring housing 3 is a sealed structure. First, the sealing ball 5 is placed on the wire 2. Since both ends of the wire 2 are equipped with fixed power connection structures, and the volume of the power connection structures is larger than that of the wire 2, the sealing ball 5 can be stretched into an approximately strip-shaped structure from the spiral seam 52 of the sealing ball 5. Then, the stretched sealing ball 5 is wrapped around the wire 2. Under the elasticity of the sealing ball 5 itself, the sealing ball 5 can return to the spherical structure, thus achieving the sealing ball 5 being placed on the outside of the wire 2. The spiral seam 52 not only allows the sealing ball 5 to be placed on the outside of the wire 2, but also ensures that there are no gaps between the spiral seams 52 after mutual compression when the sealing ball 5 is squeezed, and the structure is stable. Conversely, if the spiral seam 52 is changed to a traditional strip seam, and the strip seam is connected to the through hole 51 of the sealing ball 5, the sealing ball 5 can also be placed on the wire 2. However, when compressed, the strip seam may have increased gaps due to the force, resulting in insufficient sealing.

[0033] After the sealing ball 5 is clamped and squeezed by the two clamping plates 4, the through hole 51 of the sealing ball 5 will also be tightly attached to the outer surface of the wire 2, and the sealing ball 5 will also seal the hole through which the power supply wire 2 passes in the clamping plate 4. Thus, under the condition that the two clamping plates 4 squeeze the sealing ball 5, a good sealing effect is achieved, realizing the effect of electrical connection sealing, waterproofing and moisture prevention.

[0034] In an optional embodiment, the clamping plate 4 near the telemetry terminal housing 1 is divided into two parts at the position where the wire 2 passes through. One part is a fixed plate 41, which is fixedly connected to the inner side of one end of the wiring housing 3, and the other part is a movable plate 42, which is slidably connected to the inner side of the other end of the wiring housing 3.

[0035] In this embodiment, in order to facilitate the connection of the power connection end of the wire 2 to the terminal, the clamping plate 4 (upper clamping plate 4) near the telemetry terminal housing 1 is set as a detachable structure. The specific operation steps are as follows: first, remove the lower clamping plate 4, then move the movable plate 42 to separate the movable plate 42 from the fixed plate 41. After the movable plate 42 and the fixed plate 41 are separated, there is a large gap, which facilitates the power connection and plugging operation. After the power connection is completed, move the movable plate 42 again to return the movable plate 42 to its original position.

[0036] In an optional embodiment, the movable plate 42 is fixedly connected to a mounting plate 43 at one end located outside the wiring housing 3.

[0037] In this embodiment, the movable plate 42 can be stably fixed on the wiring housing 3 by the mounting plate 43, and the mounting plate 43 can be fixedly connected to the wiring housing 3 by screws.

[0038] In an optional embodiment, a sliding strip 7 is fixedly connected to the inner side of the wiring housing 3, and one end of the movable plate 42 is slidably connected to the surface of the sliding strip 7. The sliding strip 7 allows the movable plate 42 to slide stably, and in the fixed state, the movable plate 42 will not move arbitrarily.

[0039] In an optional embodiment, a hemispherical extrusion part 6 is provided at the position where the clamping plate 4 extrudes the sealing ball 5.

[0040] In this embodiment, in order to make the sealing ball 5 have a better waterproof sealing effect after being squeezed, a hemispherical extrusion part 6 is provided at the position where the clamping plate 4 squeezes the sealing ball 5. This ensures that the sealing ball 5 maintains its spherical shape as much as possible when it is squeezed. At the same time, the force applied to the sealing ball 5 by the hemispherical extrusion part 6 is more inclined to be directed towards the center of the sealing ball 5 compared to the direct squeezing of the sealing ball 5 by the flat clamping plate 4.

[0041] In an optional embodiment, the clamping plate 4 in the direction away from the telemetry terminal housing 1 is threadedly connected to the hemispherical extrusion part 6, and the hemispherical extrusion part 6 is a separable symmetrical structure.

[0042] In this embodiment, the lower clamping plate 4 needs to have stable structural strength, so the clamping plate 4 cannot be set as a separate structure. However, the hemispherical extrusion part 6 located on the lower clamping plate 4 can be disassembled separately. After disassembling the hemispherical extrusion part 6, the diameter of the hole left on the lower clamping plate 4 will be larger, which makes it easier for the power connection structure set at the end of the wire 2 to pass through. At the same time, the hemispherical extrusion part 6 is set as a separable structure, so that the hemispherical extrusion part 6 can be sleeved on the outside of the wire 2 by separation and splicing. Then the hemispherical extrusion part 6 is installed on the lower clamping plate 4, and the mating gap on the hemispherical extrusion part 6 can be sealed by the sealing ball 5 under the extrusion state.

[0043] In an optional embodiment, a reinforcing strip 8 is also fixedly connected to the inner side of the wiring housing 3, and the reinforcing strip 8 contacts the fixed plate 41 and the movable plate 42.

[0044] In this embodiment, when the two clamping plates 4 squeeze the sealing ball 5, the lower clamping plate 4 actively moves closer to the upper clamping plate 4 to perform the squeezing operation. In order to ensure that the movable plate 42 can move easily and has good sealing performance after installation, the movable plate 42 can only move laterally, while the lower clamping plate 4 can move longitudinally. Therefore, the added reinforcing strip 8 can better restrict the position of the upper clamping plate 4.

[0045] In an optional embodiment, the sliding strip 7 and the reinforcing strip 8 form a rectangular frame structure, and the lower clamping plate 4 can be completely disassembled. Therefore, the clamping plate 4 needs to have good sealing performance after installation. When the sliding strip 7 and the reinforcing strip 8 form a rectangular frame structure, the four sides of the lower clamping plate 4 can be completely fitted with the frame structure to ensure sealing.

[0046] In an optional embodiment, the clamping plate 4, which is away from the telemetry terminal housing 1, is detachably connected to the reinforcing strip 8 by bolts. This detachable connection with the reinforcing strip 8 can provide good connection strength without compromising the sealing performance.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
