Description

Technical Field

[0001] This utility model relates to the field of reservoir bottom sediment monitoring technology, and in particular to a water and soil conservation device for monitoring reservoir bottom sediment. Background Technology

[0002] Runoff sediment content is an important indicator for hydrological and soil and water conservation monitoring. Continuous, accurate and rapid measurement of sediment content is of great significance for carrying out soil erosion research, strengthening soil and water conservation work, controlling soil erosion, and ensuring the safe operation of water conservancy projects. The functional goal of the intelligent runoff sediment monitoring system is to measure runoff sediment in real time and continuously. It is also small in size and easy to install. The system hardware includes sediment content sensors, water level gauges, control boxes, monitoring systems, rain gauges (weather stations), solar power supply systems, poles and mounting brackets, etc.

[0003] The connection between the existing sensor and the installation structure is not flexible enough. When the sensor malfunctions and needs to be repaired, it is difficult to easily separate it from the protective frame and other structures. This makes it difficult for maintenance personnel to carry out maintenance work quickly in limited working time and complex underwater or field environments, which may lead to long-term interruption of monitoring work and affect the continuity and integrity of data. To address this, we propose a water and soil conservation monitoring device for reservoir bottom sediment volume. Utility Model Content

[0004] The purpose of this invention is to provide a device for monitoring the sediment content at the bottom of a reservoir for soil and water conservation, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water and soil conservation monitoring device for reservoir bottom sediment content, comprising a sediment content sensor and an installation mechanism disposed on its outer side, a fixing mechanism disposed below the installation mechanism, the installation mechanism comprising a protective frame and an installation bracket, the installation bracket being connected to a limiting rod via a limiting sleeve, the limiting rod being connected to a strong spring via a limiting ring, and the limiting rod being connected to a pull ring via a connecting piece.

[0006] As a preferred embodiment, the mounting bracket has a threaded groove inside, and the mounting bracket is threaded to the outer wall of the sediment content sensor through the threaded groove. There are mounting holes on both sides of the mounting bracket, and the mounting bracket is locked at the upper end of the protective frame. The sediment content sensor is located inside the protective frame.

[0007] As a preferred embodiment, the limiting sleeve is fixedly installed on the outside of the mounting hole, the limiting sleeve has a sliding cavity inside, the limiting rod is slidably connected inside the sliding cavity, the size of the limiting rod is adapted to the hole position on the protective frame, and the limiting ring is fixedly installed at the center of the outer wall of the limiting rod.

[0008] As a preferred embodiment, the strong spring is fixedly installed on the left side of the limiting ring, the strong spring is sleeved on the outer wall of the limiting rod, the end of the strong spring away from the limiting ring is fixedly installed on the left end of the sliding cavity, the connecting piece is fixedly installed on the left end of the limiting rod, and the pull ring is rotatably connected inside the connecting piece.

[0009] As a preferred embodiment, the fixing mechanism includes four sets of threaded sleeve rods and one set of connecting rods. Each of the four sets of threaded sleeve rods is internally connected to a threaded inner rod, and a ground-piercing cone is fixedly installed at the bottom of the threaded inner rod.

[0010] As a preferred embodiment, each of the four sets of threaded sleeves is fitted with a collar, and a stabilizing rod is fixedly installed on the outer wall of the collar. The end of the stabilizing rod away from the collar and both ends of the connecting rod have threaded holes, and fastening bolts are threadedly connected inside the threaded holes.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Through the set installation mechanism, the mounting bracket is connected to the outer wall of the sediment content sensor by a threaded groove. When the sensor needs to be maintained, calibrated or replaced, the staff can operate quickly, saving time and labor costs. The limit rod is connected to a strong spring through a limit ring, and the limit rod is slidably connected in the sliding cavity of the limit sleeve. When the device is installed, the pull ring is pulled down by external force, which can make the limit rod retract into the sliding cavity, which facilitates the initial docking of the mounting bracket and the protective frame. After docking is completed, the pull ring is released, and under the action of the strong spring, the limit rod automatically pops out and inserts into the hole of the protective frame to complete the fixation.

[0013] 2. Through the setting of the fixing mechanism, a design of four sets of threaded sleeve rods and threaded inner rods is adopted. The bottom of the threaded inner rod is installed with a ground anchoring cone. When the device is installed on the bottom of the tank, the extension length can be adjusted by rotating the threaded inner rod, so that the ground anchoring cone can penetrate into the mud at the bottom of the tank, providing a strong downward anchoring force and firmly fixing the entire device to the bottom of the tank. The device is connected and fixed by stabilizing rods and connecting rods, so that the entire device forms a stable frame structure. Attached Figure Description

[0024] 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.

[0025] Example 1:

[0026] Please see the appendix Figure 1 - Appendix Figure 7A device for monitoring sediment content at the bottom of a reservoir for soil and water conservation includes a sediment content sensor 1 and an installation mechanism 2 disposed on its outer side. A fixing mechanism 3 is disposed below the installation mechanism 2. The installation mechanism 2 includes a protective frame 201 and a mounting bracket 202. The mounting bracket 202 is connected to a limiting rod 207 via a limiting sleeve 205. The limiting rod 207 is connected to a strong spring 209 via a limiting ring 208. The limiting rod 207 is also connected to a pull ring 211 via a connector 210. A threaded groove 203 is formed inside the mounting bracket 202, which is threadedly connected to the outer wall of the sediment content sensor 1 via the threaded groove 203. Mounting holes 204 penetrate both sides of the mounting bracket 202. The mounting bracket 202 is secured to the upper end of the protective frame 201. Sensor 1 is located inside the protective frame 201. The limiting sleeve 205 is fixedly installed on the outside of the mounting hole 204. The limiting sleeve 205 has a sliding cavity 206 inside. The limiting rod 207 is slidably connected inside the sliding cavity 206. The size of the limiting rod 207 is adapted to the hole position on the protective frame 201. The limiting ring 208 is fixedly installed at the center of the outer wall of the limiting rod 207. The strong spring 209 is fixedly installed on the left side of the limiting ring 208. The strong spring 209 is sleeved on the outer wall of the limiting rod 207. The end of the strong spring 209 away from the limiting ring 208 is fixedly installed on the left end of the sliding cavity 206. The connecting piece 210 is fixedly installed on the left end of the limiting rod 207. The pull ring 211 is rotatably connected inside the connecting piece 210.

[0027] The pull ring 211 is rotatably connected inside the connector 210. When the operator operates the pull ring 211, it can rotate flexibly regardless of the direction of force applied, making it easy to hold and pull. The protective frame 201 surrounds the sediment content sensor 1, providing it with physical protection. The sediment content sensor 1 is existing technology. The sediment sensor is the foundation of the runoff sediment intelligent monitoring system. The monitoring system uses an infrared light transmission method sediment sensor. Its measurement principle is: when the infrared light emitted by the sensor irradiates the sediment-laden water flow, part of it is scattered and reflected by the water flow and sediment particles, and the other part is transmitted through the sediment-laden water flow. In water flows with different sediment contents, the intensity of the infrared light penetrating the water body will be different. Based on the influence law of the sediment content in the water body on the light transmission attenuation, the correspondence between different sediment contents and the voltage signal intensity generated by the transmitted light is established by calibrating the sensor.

[0028] Specifically, the mounting bracket 202 is threaded to the outer wall of the sediment content sensor 1 via a threaded groove 203. This connection method makes the installation and disassembly of the sediment content sensor 1 convenient, allowing staff to quickly perform maintenance, calibration, or replacement, saving time and labor costs. Simultaneously, mounting holes 204 penetrate both sides of the mounting bracket 202, which are fixed to the protective frame 201 via a limiting sleeve 205 and a limiting rod 207. The mounting bracket 202 is secured to the upper end of the protective frame 201, ensuring a stable installation of the entire device. Even in the complex water flow environment of a reservoir, this ensures that the sediment content sensor 1 will not easily shift, guaranteeing the accuracy and stability of the monitoring data. The protective frame 201 surrounds the sediment content sensor 1, providing physical protection. The complex environment at the bottom of a reservoir may contain debris, sand, and gravel carried by the water flow; the protective frame 201 prevents direct impact from these objects, reducing the risk of damage from external collisions, extending its service life, minimizing monitoring interruptions due to equipment failure, and ensuring the continuity of soil and water conservation monitoring.

[0029] Example 2:

[0030] Please see the appendix Figure 1 Appendix Figure 8 and attached Figure 9 Furthermore, based on Embodiment 1, the fixing mechanism 3 includes four sets of threaded sleeve rods 301 and one set of connecting rods 307. Each of the four sets of threaded sleeve rods 301 is internally threaded with an inner threaded rod 302. A ground-piercing cone 303 is fixedly installed at the bottom of the inner threaded rod 302. Each of the four sets of threaded sleeve rods 301 is fitted with a collar 304. A stabilizing rod 305 is fixedly installed on the outer wall of the collar 304. A threaded hole 306 passes through the end of the stabilizing rod 305 away from the collar 304 and both ends of the connecting rod 307. A fastening bolt 308 is threadedly connected inside the threaded hole 306.

[0031] The collar 304, which is sleeved on the outer wall of the threaded sleeve rod 301, is connected to the stabilizing rod 305. The stabilizing rod 305 is connected to the connecting rod 307 through the threaded hole 306 and the fastening bolt 308. This structure allows the device to flexibly adjust the positional relationship of the four sets of threaded sleeve rods 301 according to different reservoir bottom terrain. On uneven reservoir bottoms, the height of each threaded sleeve rod 301 can be adjusted, and then the stabilizing rod 305 and the connecting rod 307 can be used to connect and fix it, so that the entire device forms a stable frame structure. This not only adapts to diverse terrain conditions, but also connects the four sets of threaded sleeve rods 301 to each other through the connecting rod 307, further enhancing the overall stability and ensuring that the device can operate reliably in various complex reservoir bottom environments, continuously and accurately monitoring the amount of sediment at the reservoir bottom.

[0032] Specifically, the fixing mechanism 3 adopts a design with four sets of threaded sleeve rods 301 and threaded inner rods 302. The bottom of the threaded inner rods 302 is equipped with ground anchoring cones 303. When the device is installed at the bottom of the reservoir, the extension length can be adjusted by rotating the threaded inner rods 302, so that the ground anchoring cones 303 can penetrate into the mud at the bottom of the reservoir, providing a strong downward anchoring force and firmly fixing the entire device at the bottom of the reservoir. This greatly enhances the stability of the device under complex water flow impact and other conditions, ensuring that the sediment content sensor 1 is always in an accurate monitoring position and guaranteeing the reliability of the monitoring data.

[0033] The working principle of this utility model is as follows: This utility model is a device for monitoring the sediment content of a reservoir bottom in soil and water conservation. The outer wall of the sediment content sensor 1 is aligned with the threaded groove 203. By rotating the sediment content sensor 1 or the mounting bracket 202, the two are tightly connected together by threads. First, four sets of threaded sleeve rods 301 are threadedly connected to the threaded inner rods 302 respectively. During the connection process, the length of the threaded inner rod 302 extending beyond the threaded sleeve rod 301 can be initially adjusted according to the expected installation depth. The ground-piercing cone 303 fixedly installed at the bottom of the threaded inner rod 302 will be used to insert into the reservoir bottom soil. Next, the collar 304 is fitted onto the outer wall of each set of threaded sleeve rods 301, and the stabilizing rod 305 is fixedly installed on the outer wall of the collar 304. Then, the two ends of the connecting rod 307 are connected to the corresponding stabilizing rod 305 through threaded holes 306 and fastening bolts 308 to form a complete fixed frame structure. The assembled fixing mechanism 3 is transported to the monitoring point at the bottom of the reservoir. According to the topography of the reservoir bottom, the device is adjusted by rotating... The threaded sleeve 301 further precisely adjusts the length of the four sets of threaded inner rods 302, allowing the four sets of ground-piercing cones 303 to be inserted evenly and stably into the mud at the bottom of the reservoir, providing a stable support foundation for the entire device. The mounting bracket 202 with the sediment content sensor 1, along with the protective frame 201, is moved to the corresponding position above the fixing mechanism 3. The pull ring 211 is pulled, and the pull ring 211 drives the limiting rod 207 to slide to the left within the sliding cavity 206 of the limiting sleeve 205 through the connecting piece 210, compressing... When the limiting rod 207 is fully retracted into the sliding cavity 206, the mounting bracket 202 is accurately placed in the preset position of the fixing mechanism 3. The pull ring 211 is released, and under the elastic restoring force of the powerful spring 209, the limiting rod 207 pops out to the right and inserts into the matching hole on the protective frame 201, completing the connection and fixation between the mounting mechanism 2 and the fixing mechanism 3. The entire device is installed, and the sediment content sensor 1 starts to work, continuously monitoring the sediment content in the reservoir bottom water in real time.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
