Description

Technical Field

[0001] The present invention relates to the technical field of hydrographic measurement, and in particular to an eccentric semi-submersible buoy type shore temperature automatic measuring and reporting device. Background Art

[0002] Temperature is one of the important factors affecting the water environment. Since the physical and chemical properties of water and aquatic organisms are very sensitive to water temperature, changes in water temperature will have a greater impact on them. Human activities such as deforestation, urbanization, wastewater discharge, and dam interception to form reservoirs have a greater impact on river water temperature, so it is necessary to establish a river water temperature detection system to provide data for the study of river water temperature changes. At the end of the 19th century, Austria and other European countries established a river water temperature detection system to study the formation of river ice, and my country also began to pay attention to the impact of water temperature on ecology in the 1980s, making water temperature measurement a key part of my country's hydrological measurement.

[0003] At present, domestic hydrological stations mainly use manual measurement methods to measure water temperature. This method cannot achieve online real-time measurement, consumes human resources, and poses safety hazards during floods. Therefore, it is necessary to design an automatic online detection device. However, the automatic online detection device currently developed is easily entangled by floating objects in the river water and is greatly affected by changes in river water levels. Summary of the invention

[0004] In view of the above-mentioned deficiencies, the object of the present invention is to provide an eccentric semi-submersible buoy type shore temperature automatic measuring and reporting device, which can realize online unattended remote operation to measure the underwater temperature of the river bank without being affected by floating objects and changes in river water levels.

[0005] To achieve the above purpose, the technical solution provided by the present invention is:

[0006] An eccentric semi-submersible buoy type shore temperature automatic monitoring and reporting device comprises an eccentric buoy and a control room, wherein the eccentric buoy is located at the bank of a river bay, with the lower part extending into the river water and the upper part exposed to the air, a steel wire rope runs through the inside of the eccentric buoy, and both ends of the steel wire rope extend out of the eccentric buoy, the lower end of the steel wire rope is fixedly connected to a lower bracket, and the upper end is fixedly connected to an upper bracket, and the lower bracket and the upper bracket are both installed on the river bank wall, a temperature sensor probe is provided at the lower end of the eccentric buoy, and the temperature sensor probe is in contact with the river water, a wireless transmitting unit is provided at the upper end of the eccentric buoy, the control room is arranged near the river bank where the eccentric buoy is installed, and a wireless receiving unit is installed inside the control room.

[0007] As an improvement of the present invention, a through hole for accommodating a steel wire rope is provided inside the eccentric buoy, a sensor control compartment is provided above the through hole near the top of the eccentric buoy, a wireless transmitting unit and a lithium battery are installed inside the sensor control compartment, an openable end cover is provided at the upper end of the sensor control compartment, and the lower end is connected to the temperature sensor probe, an exhaust hole is provided near the temperature sensor probe near the sensor control compartment, and two counterweight holes are provided on the top of the eccentric buoy, the counterweight holes are located below the center of the eccentric buoy and on both sides of the through hole.

[0008] As an improvement of the present invention, the straight-line distance between the eccentric buoy and the control room should be less than 1000m.

[0009] As an improvement of the present invention, the steel wire rope is parallel to the slope of the river bank and has an angle with the horizontal plane between 30° and 70°.

[0010] As an improvement of the present invention, the lower support is located below the lowest water level, and the upper support is located above the highest water level.

[0016] The beneficial effects of the present invention are:

[0017] 1. In the present invention, the eccentric buoy is an eccentric structure and is cylindrical, so it can maintain stability and prevent floating objects from being entangled by the rotation of the eccentric buoy itself.

[0018] 2. In the present invention, the outer shell of the eccentric float is made of corrosion-resistant and aging-resistant plastic, and the internal gap is filled with foam, so that it can maintain buoyancy and have anti-collision and durable functions.

DETAILED DESCRIPTION

[0027] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0028] See also Figures 1 to 3An eccentric semi-submersible buoy type shore temperature automatic monitoring and reporting device includes an eccentric buoy 1 and a control room 2. The eccentric buoy 1 is located at the bank of a river bay. The bank of the river bay preferably has a certain slope to reduce the impact of floods during the flood season and avoid some floating objects. It can also reduce the cost of laying materials without affecting the passage of the waterway. The eccentric buoy 1 can use its own buoyancy to move up and down on the steel wire rope 3 as the water level changes and always keep floating, so that its lower part is located in the river water and its upper part is exposed to the air, and the steel wire rope 3 is protected from being entangled with floating objects such as water plants. The eccentric A steel wire rope 3 passes through the inside of the buoy 1, and both ends of the steel wire rope 3 extend out of the eccentric buoy 1. The lower end of the steel wire rope 3 is fixedly connected to the lower bracket 4, and the upper end is fixedly connected to the upper bracket 5. The lower bracket 4 and the upper bracket 5 are both installed on the river bank wall. A temperature sensor probe 11 is provided at the lower end of the eccentric buoy 1, and the temperature sensor probe 11 is in contact with the river water. A wireless transmitting unit 12 is provided at the upper end of the eccentric buoy 1. The control room 2 is arranged near the river bank where the eccentric buoy 1 is installed, and a wireless receiving unit 21 is installed inside the control room 2.

[0029] Please continue reading Figure 2 and Figure 3 Specifically, a through hole 13 for accommodating the steel wire rope 3 is opened inside the eccentric buoy 1, and a sensor control compartment 14 is provided above the through hole 13 near the top of the eccentric buoy 1. A wireless transmitting unit 12 and a lithium battery are installed inside the sensor control compartment 14. An openable end cover is provided at the upper end of the sensor control compartment 14 to facilitate replacement of the lithium battery, and the lower end is connected to the temperature sensor probe 11. An exhaust hole 15 is provided near the temperature sensor probe 11 near the sensor control compartment 14. Two counterweight holes 16 are provided on the top of the eccentric buoy 1. The counterweight holes 16 are located below the center of the eccentric buoy and on both sides of the through hole 13. The temperature sensor probe 11 is kept 0.5m below the water surface by the counterweight and the eccentric buoy 1 is kept stable.

[0030] In this embodiment, the straight-line distance between the eccentric buoy 1 and the control room 2 should be less than 1000m, so as to save energy and not increase the transmission power of the wireless signal. Therefore, a wireless communication system with a transmission distance of 1 km should be selected during use.

[0031] In this embodiment, the steel wire rope 3 is parallel to the slope of the river bank and has an angle of 30° to 70° with the horizontal plane, so that the eccentric buoy 1 can slide freely on the steel wire rope 3 and is easy to maintain.

[0032] In this embodiment, the lower bracket 4 is located below the lowest water level, and the upper bracket 5 is located above the highest water level, so that the eccentric buoy 1 can be used normally with a margin at both the highest water level and the lowest water level.

[0033] In this embodiment, the steel wire rope 3 is provided with a self-tensioning device and an overload locking device. The setting of the self-tensioning device ensures that the tension of the steel wire rope 3 remains consistent when the temperature changes in winter and summer, thereby not affecting the free sliding of the eccentric buoy 1 on the steel wire rope. In addition, during flood season, when the eccentric buoy 1 and the steel wire rope 3 are subjected to a strong impact or collide with floating objects and the force suddenly increases, the overload locking device can be immediately locked to protect the self-tensioning device from being damaged.

[0034] In this embodiment, the eccentric buoy 1 is cylindrical. When the eccentric buoy 1 is entangled with floating objects, it will automatically float away due to the rotation of the eccentric buoy 1, thereby preventing the floating objects from being entangled and sinking into the water. The eccentric structure of the eccentric buoy 1 can solve the problem of stable depth measurement.

[0035] The shell 17 of the eccentric float 1 is made of corrosion-resistant and aging-resistant plastic, such as PVC, so as to reduce the weight of the eccentric float 1 and allow wireless signals to pass through the shell 17. In addition, the measuring equipment in the eccentric float 1 is completely sealed in the shell 17 to avoid sun and rain and extend the life of the equipment. The internal gap 18 of the eccentric float 1 is filled with foam to enhance its anti-collision ability without affecting the buoyancy of the eccentric float 1. Therefore, when the shell 17 of the eccentric float 1 is damaged, its buoyancy will not be reduced, thereby ensuring its normal measurement.

[0036] In this embodiment, the vertical distance between the temperature sensor probe 11 and the water surface is 0.5 m. The eccentric buoy 1 is provided to ensure that the floating distance remains unchanged and will not easily roll over to change the distance, so that the measurement data is valid.

[0037] In this embodiment, the steel wire rope 3, the lower bracket 4 and the upper bracket 5 are all made of stainless steel to prevent corrosion and extend their service life.

[0038] In this embodiment, the bases of the lower bracket 4 and the upper bracket 5 are cast by reinforced concrete to ensure their strength and fix the brackets.

[0039] In this embodiment, an armored platinum resistor and a temperature sensor that meets the measurement accuracy are selected. The measuring device inside the entire eccentric buoy 1 is powered by a lithium battery, and the whole machine is required to have low power consumption to ensure that the device can be used normally without replacing the battery within half a year. All measuring components in the sensor control compartment 14 are made into an openable plastic shell with IP68 protection grade for protection.

[0040] In this embodiment, weeds and shrubs within 10 m around the steel wire rope 3 should be regularly cleared to create a maintenance path under the steel wire rope 3 so that maintenance can be easily performed when a fault occurs at any water level within the designed use range.

[0041] The working principle of the present invention is:

[0042] The present invention installs the eccentric buoy 1 on the river bank by installing a lower bracket 4 below the lowest water surface and an upper bracket 5 on the highest water surface on the river bank, and a steel wire rope 3. Due to the buoyancy of the eccentric buoy 1 itself and the effect of the counterweight hole 16, the lower part of the eccentric buoy 1 is located in the water, and the upper part is exposed to the air, and the vertical distance between the temperature controller probe 11 installed inside the eccentric buoy 1 and the water surface is always maintained at 0.5m. The steel wire rope 3 is equipped with a self-tensioning device and an overload locking device, so that the eccentric buoy 1 can move up and down on the steel wire rope 3 by its own buoyancy when the water level changes. In addition, the eccentric buoy 1 is cylindrical and can use its own rotation to prevent floating objects from getting entangled. When the temperature controller probe 11 detects the temperature of the water, the detected temperature is transmitted to the wireless receiving unit 21 installed in the control room 2 through the wireless transmitting unit 12 installed in the sensor control compartment 14, so that the bank temperature is remotely obtained, saving labor costs and achieving safe and effective operation.

Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the present invention.
