Description

Technical Field

[0001] The present application relates to the technical field of water level monitoring, and in particular to a water level monitoring device for a water conservancy project. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. Water conservancy projects can prevent floods, regulate and distribute water, and meet people's needs for water resources in life and production. Therefore, water levels need to be monitored during the operation of water conservancy projects to facilitate people's response to floods.

[0003] Since the monitoring device needs to provide timely feedback on the water level, it is necessary to give an alarm in time when the water level exceeds the warning line so that relevant staff can prepare waterproofing work in advance. A patent application number is proposed in the related technology: CN202220770495.6, which provides a water level monitoring device for a water conservancy project. When the water level is too high, the water flow drives the float to move upward, and the float drives the light rod to move upward. The light rod applies pressure to the extrusion part through the transmission mechanism, and the extrusion part applies pressure to the pressure sensor. The pressure sensor controls the alarm through the microcontroller to start the alarm, thereby playing a role in water level monitoring and being able to issue an alarm in time, so that relevant staff can prepare waterproofing work in advance.

[0004] However, in actual use, the height of the monitoring component needs to be adjusted according to different working conditions. The device in the related art cannot adjust the height of the monitoring component, which may lead to omissions or false alarms in water level monitoring. Summary of the Invention

[0037] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0038] The water level monitoring device for a water conservancy project in an embodiment of the present application includes: a base 1, a mounting seat 2, a mounting plate 5, a height adjustment mechanism 15 and a monitoring mechanism 16. The base 1 is provided with a mounting groove for installing the mounting seat 2. The adjusting mechanism 15 is installed on the mounting plate 5. The lower end of the adjusting mechanism 15 is connected to the monitoring mechanism 16. The adjusting mechanism 15 is used to change the height of the monitoring mechanism 16 in the upper and lower directions.

[0039] The present application provides a water level monitoring device for a water conservancy project, which can adjust the height of the water level monitoring mechanism, that is, the height of the monitoring mechanism 16 in the up and down directions, thereby improving the accuracy of water level monitoring.

[0040] Specifically, if Figures 1 to 12As shown, the base 1 is provided with a mounting groove facing upward, and an adjusting mechanism 15 is provided at the lower end of the mounting plate 5. The adjusting structure is connected to the monitoring mechanism 16. The adjusting mechanism 15 is used to adjust the height of the monitoring mechanism 16 in the up and down directions so that the monitoring device can be adapted to different usage environments, thereby avoiding omissions or false alarms in water level monitoring due to different usage environments and improving the accuracy of water level monitoring.

[0041] The water level monitoring device for a hydraulic project in the embodiment of the present application can adjust the height of the water level monitoring mechanism to improve the accuracy of water level monitoring. Compared to water level monitoring devices designed for fixed-height installation, which lack dynamic adjustment capabilities and cannot accurately match actual water level changes under complex working conditions (such as tides, seasonal water level fluctuations, reservoir scheduling, etc.), the present application can adjust the height of the monitoring mechanism 16 in the vertical direction according to actual conditions, thereby improving the accuracy of water level monitoring.

[0042] In some embodiments, the adjustment mechanism 15 includes two fixed seats 1501 symmetrically fixed at the bottom of the mounting plate 5, and a rotating shaft 1502 is rotatably connected between the two fixed seats 1501 through a bearing. A servo motor 1503 and a telescopic sleeve 1506 are fixed to the bottom of the mounting plate 5, and the output shaft end of the servo motor 1503 is fixedly connected to one end of the rotating shaft 1502. Two sleeves 1504 are symmetrically fixed on the outer surface of the rotating shaft 1502, and a connecting rope 1505 is fixed on the outer surface of the sleeve 1504. The monitoring mechanism 16 includes a fixed plate 14 and a monitoring component. A monitoring component is provided at the lower end of the fixed plate 14. The bottom end of the connecting rope 1505 is fixedly connected to the fixed plate 14 through a hook. Four telescopic sleeves 1506 are symmetrically fixed between the mounting plate 5 and the fixed plate 14.

[0043] Specifically, if Figures 1 to 12 As shown, the adjustment mechanism 15 includes two fixed seats 1501 symmetrically fixed at the bottom of the mounting plate 5, and a rotating shaft 1502 is rotatably connected between the two fixed seats 1501 through a bearing. A servo motor 1503 is fixed to the bottom of the mounting plate 5, and the output shaft end of the servo motor 1503 is fixedly connected to one end of the rotating shaft 1502. Two sleeves 1504 are symmetrically fixed on the outer surface of the rotating shaft 1502, and a connecting rope 1505 is fixed on the outer surface of the sleeve 1504. The bottom end of the connecting rope 1505 is fixedly connected to the fixing plate 14 through a hook, and four telescopic sleeve rods 1506 are symmetrically fixed between the mounting plate 5 and the fixing plate 14.

[0044] In the water level monitoring device for water conservancy projects implemented by the present invention, when it is necessary to adjust the height of the monitoring mechanism 16, the servo motor 1503 is started, and the servo motor 1503 drives the rotating shaft 1502 to rotate, so that the sleeve 1504 rotates together, and the connecting rope 1505 wrapped around the outer surface of the sleeve 1504 is loosened, thereby driving the fixed plate 14 to move up and down, and the monitoring mechanism 16 moves together, so that the height of the monitoring mechanism 16 can be changed, which is convenient for adjusting the position where the water level needs to be monitored according to actual needs, and is convenient for adjustment. At the same time, through the position of the telescopic sleeve 1506, the shaking of the fixed plate 14 during the lifting process is avoided, thereby enhancing stability.

[0045] In some embodiments, the monitoring component includes four sliding rods 1601 slidably connected to the fixed plate 14, a pressure plate 1602 is fixed to the bottom end of the sliding rod 1601, and a buffer spring 1603 is sleeved on the outer surface of the sliding rod 1601. The two ends of the buffer spring 1603 are respectively fixedly connected to the fixed plate 14 and the pressure plate 1602. The bottom of the pressure plate 1602 is fixed with a baffle 1605 through a connecting rod 1604. The bottom of the fixed plate 14 is fixed with a pressure sensor 1606. The PLC controller 8 is electrically connected to the alarm 10 and the pressure sensor 1606. The baffle 1605 is hemispherical or spherical.

[0046] Specifically, if Figures 1 to 12 As shown, the monitoring mechanism 16 includes four sliding rods 1601 slidably connected in the fixed plate 14, a pressure plate 1602 is fixed to the bottom end of the sliding rod 1601, and a buffer spring 1603 is sleeved on the outer surface of the sliding rod 1601. The two ends of the buffer spring 1603 are respectively fixedly connected to the fixed plate 14 and the pressure plate 1602. The bottom of the pressure plate 1602 is fixed with a baffle 1605 through a connecting rod 1604. The bottom of the fixed plate 14 is fixed with a pressure sensor 1606. The PLC controller 8 is electrically connected to the alarm 10 and the pressure sensor 1606. A protective shell 21 is fixed on the mounting base 2, and the protective shell 21 is located above the PLC controller 8 and the alarm 10.

[0047] The water level monitoring device for a water conservancy project in the embodiment of the present invention generates an impulse on the baffle 1605 when the water level rises, driving the baffle 1605 and the pressure plate 1602 to move upward, thereby driving the slide bar 1601 to slide upward in the fixed plate 14, compressing the buffer spring 1603, and causing the pressure plate 1602 to contact the pressure sensor 1606. When the pressure sensor 1606 is under pressure, the signal is transmitted to the PLC controller 8. After receiving the signal, the PLC controller 8 controls the alarm 10 to sound, reminding the staff to take precautions in advance. Be well prepared and complete the monitoring operation. Through the setting of the baffle 1605, the water flow is prevented from directly impacting the pressure sensor 1606, thereby extending the service life of the pressure sensor 1606. Through the setting of the protective shell 21, the PLC controller 8 and the alarm 10 are protected to prevent foreign objects from causing damage to the PLC controller 8 and the alarm 10. Among them, the model of the PLC controller 8 is OHR-PR, the model of the pressure sensor 1606 is the existing KPS-YL pressure sensor 1606, and the model of the alarm 10 is the existing YS-H alarm 10.

[0050] In the present invention, when it is necessary to fix the base 1 and the mounting base 2, the staff rotates the rotating rod 401, and the rotating rod 401 drives the first main bevel gear plate 402 to rotate. Since the first main bevel gear plate 402 is meshed and connected with the first bevel gear plate 403, the two first bevel gear plates 403 are driven to rotate, and the first bevel gear plate 403 drives the threaded rod 404 to rotate, and cooperates with the sliding connection of the fixed shell 19 and the connecting head 20 to limit the threaded block 405 to prevent the threaded block 405 from rotating, thereby driving the two threaded blocks 405 to move to both sides in the horizontal direction, so that the connecting strip 406 and the fixing rod 407 move together, so that the fixing rod 407 is inserted into the corresponding fixing hole 3, completing the fixation between the base 1 and the mounting base 2.

[0057] Specifically, if Figures 1 to 12As shown, a fixing box 6 is fixed on the mounting plate 5, a first limiting shell 7 is fixed on the fixing box 6, a PLC controller 8 slides in the first limiting shell 7, a second limiting shell 9 is fixed on the fixing box 6, an alarm 10 slides in the second limiting shell 9, a second mounting mechanism 12 for limiting the PLC controller 8 and the alarm 10 is linked to the first mounting mechanism 4 through a connecting mechanism 11, an anti-loosening mechanism 13 for preventing the connecting mechanism 11 from starting is provided on one side of the mounting seat 2, a fixing plate 14 is provided below the mounting plate 5, an adjusting mechanism 15 for changing the height of the fixing plate 14 is installed on the mounting plate 5, and a monitoring mechanism is provided at the bottom of the fixing plate 14. Measuring mechanism 16, four rectangular blocks 17 are symmetrically fixed on both sides of the base 1, and mounting holes 18 are opened on the rectangular blocks 17. The anti-loosening mechanism 13 includes a rectangular box 1301 fixed to one side of the mounting seat 2, and a return spring 1302 is fixed in the rectangular box 1301. A connecting block 1303 is fixed to one end of the return spring 1302, and a pressing rod 1304 is fixed to one side of the connecting block 1303. The pressing rod 1304 slides through a side wall of the rectangular box 1301, and a fixing tooth 1305 is fixed to the outer surface of the knob 1105. A limiting tooth 1306 engaged with the fixing tooth 1305 is fixed to one side of the connecting block 1303.

[0058] In the present invention, when turning the knob 1105, the staff slides the pressing rod 1304 horizontally toward the position of the rectangular box 1301, driving the connecting block 1303 to compress the reset spring 1302, so that the limiting tooth 1306 releases the restriction on the fixed tooth 1305. Then, the staff turns the knob 1105 again to install the mounting base 2, PLC controller 8 and alarm 10. After the installation is completed, the pressing rod 1304 is released, and the elastic force of the reset spring 1302 is used to reset the limiting tooth 1306 and limit the fixed tooth 1305. This can prevent the knob 1105 from being affected by external forces and rotating, thereby preventing the electrical appliance from falling.

[0059] Furthermore, two fixing shells 19 are symmetrically fixed in the mounting base 2 , and a connector 20 is fixed to the bottom of each threaded block 405 , and the connector 20 slides in the corresponding fixing shell 19 .

[0060] Furthermore, a protective shell 21 is fixed on the mounting base 2, and the protective shell 21 is located above the PLC controller 8 and the alarm 10. Four rectangular blocks 17 are symmetrically fixed on the two sides of the base 1, and mounting holes 18 are provided on the rectangular blocks 17 to facilitate the installation of the base 1 on the ground.

[0061] When installing the water level monitoring device according to the embodiment of the present invention, the pin is inserted into the mounting hole 18, the base 1 is fixed to the ground next to the water level monitoring to enhance stability, the mounting seat 2 is inserted into the base 1, the PLC controller 8 and the alarm 10 are respectively placed in the first limiting shell 7 and the second limiting shell 9, and they are preliminarily installed. The staff starts the connecting mechanism 11, and the linkage effect of the connecting mechanism 11 drives the first mounting mechanism 4 and the second mounting mechanism 12 to operate simultaneously. The fixing hole 3 is limited by the first mounting mechanism 4, so that the base 1 and the mounting seat 2 are fixed. When the position of the device needs to be changed next time, there is no need to pull out the pin, which is more convenient. The PLC controller 8 and the alarm 10 are installed through the second installation mechanism 12 without the need to tighten multiple bolts, which reduces labor intensity and increases installation efficiency. When the PLC controller 88 and the alarm 1010 need to be installed, the bidirectional screw 1201 is rotated, and the moving block 1202 and the limit rod 1203 are slidably connected to limit the position, thereby driving the two moving blocks 1202 to move toward the middle in the horizontal direction, so that the fixed blocks 12041204 and the insertion rod 1205 move together, and the insertion rod 1205 is inserted into the corresponding socket 1206 to complete the installation of the PLC controller 88 and the alarm 1010. There is no need to tighten multiple bolts, which reduces labor intensity.

[0062] By setting the connecting mechanism 11, the first mounting mechanism 4 and the second mounting mechanism 12 can be connected. By adopting the mechanical transmission method, the mounting base 2, the PLC controller 8 and the alarm 10 can be installed together at the same time, which is very convenient, conducive to maintenance, and improves work efficiency. By setting the anti-loosening mechanism 13, the connecting mechanism 11 can be limited to prevent the connecting mechanism 11 from rotating due to the influence of external forces, thereby avoiding the phenomenon of loosening after being fixed by bolts and subjected to the impact of water flow for a long time, thereby enhancing stability. After installation, the position of the fixing plate 14 is adjusted by the adjusting mechanism 15, so that the height of the monitoring mechanism 16 in the vertical direction is changed together, and the monitoring mechanism 16 is adjusted to the position to be monitored. The position where the water level needs to be monitored can be changed according to actual needs. The water level is monitored by the monitoring mechanism 16. When the water level exceeds the warning line, a signal can be sent in time to remind the staff to prepare in advance.

[0063] When it is necessary to fix the base 1 and the mounting seat 2, the staff rotates the rotating rod 401, and the rotating rod 401 drives the first main bevel gear disc 402 to rotate. Since the first main bevel gear disc 402 is meshed and connected with the first bevel gear disc 403, the two first bevel gear discs 403 are driven to rotate. The first bevel gear disc 403 in turn drives the threaded rod 404 to rotate, and the fixed shell 19 and the connecting head 20 are slidably connected to limit the threaded block 405 to prevent the threaded block 405 from rotating. Then, the two threaded blocks 405 are driven to move to both sides in the horizontal direction, so that the connecting strip 406 and the fixing rod 407 move together, so that the fixing rod 407 is inserted into the corresponding fixing hole 3, completing the fixation between the base 1 and the mounting seat 2. When replacing the base 1 and the mounting seat 2 next time, there is no need to pull out the pin every time to replace the base 1, which is more convenient. The above is a detailed introduction to the method provided by the present application. This article uses specific examples to illustrate the principles and implementation methods of the present application. The description of the above embodiment is only used to help understand the method and core ideas of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
