Description

Technical Field

[0001] The utility model relates to the technical field of water level detection, in particular to a water level detection device for water conservancy and hydropower. Background Technique

[0002] Water conservancy and hydropower is a broad and important field, covering the development, utilization, protection and management of water resources, as well as the construction and operation of water conservancy projects. In order to make full use of natural water resources, humans control the water flow by building water conservancy projects, carry out water allocation and use. In order to ensure the safety of water conservancy projects, the detection of water level is also essential.

[0003] The existing methods for water level detection mostly use a vertical scale, and the height of the water level is determined by the scale lines on the scale and the water surface. However, this water level detection depends on the human eye for viewing, and the scale is generally set in the water conservancy area, which is not convenient for viewing. And some water level detectors such as radar water level gauges have high construction costs and high costs. Therefore, technical personnel in this field have proposed a water level detection device for water conservancy and hydropower to solve the problems raised in the above background. Content of the Utility Model

[0004] The purpose of the utility model is to provide a water level detection device for water conservancy and hydropower to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A water level detection device for water conservancy and hydropower, including a base, a column is installed on the base, and a top plate is installed at one end of the column away from the base; a plurality of scale lines distributed in a ring shape are arranged on the surface of the column, a movable frame is slidably arranged on the column, a ring-shaped floating ball is installed at the bottom of the movable frame, a plurality of U-shaped rods distributed in a ring shape are installed on the movable frame, the U-shaped rods are slidably connected with the top plate, a movable plate is slidably arranged in the column, the movable plate is fixedly connected with the U-shaped rods, and further includes:

[0007] A water level measuring mechanism, which is arranged in the column and connected with the movable plate for detecting the water level.

[0008] As a further scheme of the utility model: a bracket is installed on the top plate, and a solar panel and a power module are installed on the bracket.

[0009] As a still further scheme of the utility model: the water level measuring mechanism includes a resistance strip installed in the column, a conductive slider is arranged in the movable plate and is in contact with the resistance strip, and a control module is installed on the bracket.

[0010] As a further solution of the utility model: a warning light is installed at the center position of the top plate.

[0011] As a further solution of the utility model: an annular transparent protective shell is provided between the base and the top plate, and filter holes are provided on the transparent protective shell.

[0012] As a further solution of the utility model: a plurality of insertion rods distributed in a ring shape are provided at the bottom of the base.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: when the utility model is in use, the device is inserted into the bottom of the water conservancy project through the insertion rods, so that the device can be stably fixed in the water, and thus will not be affected by the flowing water, which is convenient for accurately detecting the water level. When detecting the water level, due to the existence of the floating ball, the floating ball will always float on the water surface, so that the water level height can be directly obtained according to the scale line corresponding to the position of the floating ball. And when the height of the floating ball changes, the height of the U-shaped rod also changes, so that the height of the movable plate in the column also changes accordingly, and further the measurement data of the water level measuring mechanism changes. The water level height is calculated through the measurement data of the water level measuring mechanism, and the measured data is transmitted to the computer display screen used by the detector, so that the detector does not need to observe the scale line on the spot to record the water level height. At the same time, when the water level height calculated by the water level measuring mechanism exceeds the set threshold, a warning will be processed. In addition, the device can be powered independently by the corresponding solar panel and power supply module, and the use effect is better. In addition, the impurities in the water can be filtered through the set transparent protective shell and filter holes, avoiding the contact between the impurities in the water and the movable frame and the floating ball, resulting in the attachment of impurity garbage on the surfaces of the movable frame and the floating ball, which causes the weight to increase and affects the normal floating of the floating ball.

Specific implementation manner

[0019] The technical solution of this patent will be further described in detail below in conjunction with the specific implementation manner.

[0020] Please refer to Figures 1-4 , a water level detection device for water conservancy and hydropower, including a base 1, a cylinder 3 is installed on the base 1, and a top plate 4 is installed at one end of the cylinder 3 away from the base 1; a plurality of scale lines 5 distributed in a ring shape are provided on the surface of the cylinder 3, a movable frame 10 is slidably arranged on the cylinder 3, a ring-shaped floating ball 11 is installed at the bottom of the movable frame 10, a plurality of U-shaped rods 12 distributed in a ring shape are installed on the movable frame 10, the U-shaped rods 12 are slidably connected with the top plate 4, a movable plate 13 is slidably arranged in the cylinder 3, the movable plate 13 is fixedly connected with the U-shaped rods 12, and further includes:

[0021] A water level measuring mechanism, which is arranged in the cylinder 3 and connected with the movable plate 13 for detecting the water level.

[0022] When detecting the water level, due to the existence of the floating ball 11, the floating ball 11 will always float on the water surface, so that the water level height can be directly obtained according to the scale line 5 corresponding to the position of the floating ball 11. And when the height of the floating ball 11 changes, the height of the U-shaped rod 12 also changes, making the height of the movable plate 13 in the cylinder 3 also change accordingly, and further making the measurement data of the water level measuring mechanism change. The water level height is calculated through the measurement data of the water level measuring mechanism, and the measured data is transmitted to the computer display screen used by the tester. Thus, there is no need for the tester to observe the scale line 5 on the spot to record the water level height. At the same time, when the water level height calculated by the water level measuring mechanism exceeds the set threshold, a warning will be processed. This utility model is convenient for the tester to obtain the water level height data during use, and at the same time, the overall structure is simple and the cost is low, having practicability.

[0023] In a situation of this embodiment, a bracket 6 is installed on the top plate 4, and a solar panel 7 and a power module 8 are installed on the bracket 6.

[0024] This device absorbs solar energy through the solar panel 7 on the bracket 6 to convert it into power, and stores the electric energy through the power module 8. The power module 8 is used to supply power to this device.

[0025] In one case of this embodiment, the water level measuring mechanism includes a resistance strip 15 installed in the column 3. A conductive slider 14 that fits against the resistance strip 15 is provided in the movable plate 13. A control module 9 is installed on the bracket 6. The resistance strip 15, the power supply module 8, and the control module 9 are electrically connected.

[0026] It should be noted that the functions of the conductive slider 14 and the resistance strip 15 in this embodiment are similar to those of a sliding rheostat. Only the upper part of the resistance strip 15 above the conductive slider 14 is connected to the circuit in this embodiment.

[0027] When the water level changes, the floating ball 11 will rise and fall, and at the same time drive the U-shaped rod 12 to rise and fall, causing the movable plate 13 to also rise and fall in the column 3, thereby changing the position of the conductive slider 14 on the resistance strip 15. When the floating ball 11 rises, the movable plate 13 also rises. At this time, the part of the resistance strip 15 connected to the circuit becomes shorter, making the overall resistance value of the circuit larger, and thus the current in the circuit becomes larger. When the floating ball 11 descends, the movable plate 13 also descends. At this time, the part of the resistance strip 15 connected to the circuit becomes longer, making the overall resistance value of the circuit smaller, and thus the current in the circuit becomes smaller. The current in the circuit is detected by a current detector, and the control module 9 is used to convert the current detected by the current detector, thereby calculating the water level height data where the floating ball 11 is located, and sending the calculated water level height data to the computer display screen of the detection personnel, so that the detection personnel can remotely obtain the water level height, without the need for the detection personnel to observe the scale line 5 on-site to record the water level height. Moreover, the overall mechanism is simple and the cost is low, making it practical.

[0028] In one case of this embodiment, a warning light 16 is installed at the center position of the top plate 4.

[0029] When the water level height calculated by the water level measuring mechanism exceeds the set threshold, the warning light 16 will give a warning, reminding the surrounding staff to handle it quickly, and sending the alarm information to the computer display screen of the detection personnel, playing a warning role.

[0030] In one case of this embodiment, an annular transparent protective shell 17 is provided between the base 1 and the top plate 4. Filter holes 18 are provided on the transparent protective shell 17.

[0031] The impurities in the water can be filtered through the provided transparent protective shell 17 and the filter holes 18, preventing the impurities in the water from contacting the movable frame 10 and the floating ball 11, resulting in the attachment of impurity garbage on the surfaces of the movable frame 10 and the floating ball 11, increasing the weight and affecting the normal floating of the floating ball 11. The transparent protective shell 17 is made of a transparent material as a whole, so it does not affect the human eye to observe the scale line 5.

[0032] In one case of this embodiment, a plurality of insertion rods 2 distributed in a ring are provided at the bottom of the base 1.

[0033] The device is inserted into the bottom of the water conservancy project through the insertion rods 2, so that the device can be stably fixed in the water and will not be affected by the flowing water, facilitating accurate detection of the water level.

[0034] When the utility model is in use, the device is inserted into the bottom of the water conservancy project through the insertion rods 2, so that the device can be stably fixed in the water and will not be affected by the flowing water, facilitating accurate detection of the water level. When the water level is detected, due to the presence of the floating ball 11, the floating ball 11 will always float on the water surface, so that the water level height can be directly obtained according to the scale line 5 corresponding to the position of the floating ball 11. And when the height of the floating ball 11 changes, the height of the U-shaped rod 12 also changes, causing the height of the movable plate 13 in the column 3 to change accordingly, and further causing the measurement data of the water level measuring mechanism to change. The water level height is calculated through the measurement data of the water level measuring mechanism, and the measured data is transmitted to the computer display screen used by the tester, so that the tester does not need to observe the scale line 5 on the spot to record the water level height. At the same time, when the water level height calculated by the water level measuring mechanism exceeds the set threshold, a warning will be processed. In addition, the device can be powered autonomously by the corresponding solar panel 7 and power module 8, and the use effect is better. In addition, the transparent protective shell 17 and filter holes 18 provided can filter impurities in the water, preventing the impurities in the water from contacting the movable frame 10 and the floating ball 11, resulting in the attachment of impurity garbage on the surfaces of the movable frame 10 and the floating ball 11, which increases the weight and affects the normal floating of the floating ball 11.
