Description

Technical Field

[0001] The invention relates to the technical field of water level monitoring, and in particular to a water level monitoring device used in water conservancy and hydropower projects. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater in order to achieve the purpose of eliminating harm and promoting benefits. Their main functions include flood control, irrigation, water supply, power generation, shipping, aquaculture, and improving the ecological environment. Through reasonable planning, design and construction of water conservancy projects, the temporal and spatial distribution of water resources can be effectively adjusted to meet the various needs of human society for water resources, while reducing the impact of water and drought disasters and promoting the sustainable development of the economy and society.

[0003] A float-type water level gauge is an instrument used to measure water level height. It measures water level by driving a mechanical device via a float as the water level rises and falls. It can provide real-time and accurate water level data, providing an important basis for the operation and management of water conservancy projects, scheduling decisions, and flood prevention and early warning.

[0004] During the use of existing float-type water level gauges, garbage often floats on the water surface, and these garbage will impact the float-type water level gauge under the action of water flow. Although the current water level gauges are usually equipped with protective devices on their outside, once the water flow is large such as in the flood season, the impact force of the garbage driven by the water flow on the protective device will also increase significantly, and may even directly destroy the protective device and the water level gauge, thereby increasing the loss and affecting the service life of the water level gauge.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figures 1 to 10 As shown, the present invention provides an embodiment:

[0042] A water level monitoring device for water conservancy and hydropower engineering comprises a column 1, the top of the column 1 is rotatably connected to a movable seat 2, the outer wall of the movable seat 2 is fixedly connected to a connecting seat 3, the interior of the connecting seat 3 is slidably connected to a movable block 4, a slide rail is installed between the movable block 4 and the connecting seat 3, a storage component and a protection component are arranged at the bottom of the connecting seat 3, a driving component is arranged between the movable seat 2 and the connecting seat 3, a water level gauge 8 is arranged at the bottom of the storage component, and the top of the column 1 is fixedly connected to a support rod 9.

[0043] The column 1 and the water level gauge 8 are existing structures for water level monitoring in water conservancy and hydropower projects. The column 1 mainly provides a stable installation foundation for various components to ensure that monitoring can be carried out stably. As a reference point for measuring water level, it is mainly installed on the shore and measuring points opened on the building. The water level gauge 8 is mainly located in the water to monitor the water level. The movable seat 2 rotatably installed on the column 1 can provide an installation foundation for the connecting seat 3, and when the impact force borne by the protective component exceeds its maximum protection level, the water level gauge 8 is driven back to the shore through the connecting seat 3, so as to play a more effective protective role and effectively avoid the impact of water flow on the water level gauge 8. The protective component and the storage component can be linked through the movable block 4 to ensure that they can be synchronized to avoid affecting the collision and storage of the water level gauge 8.

[0044] The storage assembly includes a storage seat 701 fixedly connected to the bottom of the connecting seat 3, and the interior of the storage seat 701 is rotatably connected to a mounting block 703 (such as Fig.10 As shown in the figure, the water level gauge 8 is fixedly connected to the bottom of the mounting block 703, the interior of the storage seat 701 is slidably connected to the slide seat 702 through a guide rail, the outer side of the mounting block 703 is symmetrically slidably connected to the slider 706, the slide seat 702 and the slider 706 are rotatably connected with a connecting rod 704, the slide seat 702 is fixedly connected to the movable block 4, the connecting rod 704 is a pressure telescopic rod, the outer wall of the mounting block 703 is symmetrically and obliquely provided with a slide groove 705, the sliders 706 are slidably connected to the inner side of the slide groove 705, and a spring 2 707 is fixedly connected between the slider 706 and the inner wall of the slide groove 705.

[0045] The storage seat 701 can provide an installation foundation for the rotation installation of the mounting block 703 and the sliding installation of the slide 702, ensuring that the slide 702 can stably slide inside the storage seat 701 through the guide rail. The mounting block 703 can realize the installation of the water level gauge 8, and drive the water level gauge 8 to rotate in the storage seat 701 to achieve storage after collision. The slide 702 can realize the synchronization of the water level gauge 8 and the movable block 4, so that the movable block 4 can drive the water level gauge 8 to rotate to achieve storage and reset. The connecting rod 704 can drive the mounting block 703 to rotate for storage, and can also realize the reset support of the mounting block 703, ensuring the synchronization between the movable block 4 and the water level gauge 8, and improving the timeliness and safety of collision storage.

[0046] The protection component includes a mounting seat 601 fixedly connected to the bottom of the connecting seat 3, a connecting block 608 is rotatably connected inside the mounting seat 601, a connecting plate 602 is fixedly connected to the side of the connecting block 608 away from the connecting seat 3, a clamping block 605 is fixedly connected to the top of the connecting plate 602, a baffle 604 is fixedly connected to the bottom of the connecting plate 602, a support plate 606 is fixedly connected to the bottom of the connecting seat 3, a fixing rod 603 is fixedly connected to the inner side of the connecting block 608, an end of the fixing rod 603 close to the movable seat 2 passes through the mounting seat 601, a guide block 607 is fixedly connected to the lower surface of the movable block 4, the guide block 607 is slidably connected to the outer side of the fixing rod 603, and a fixing sleeve 609 (such as Fig. 9 As shown, a torsion spring 610 is fixedly connected between the fixed sleeve 609 and the fixed rod 603, a guide groove is provided on the outer side of the fixed rod 603, and the guide groove is composed of an annular groove, a spiral groove and a straight groove. A convex block slidably connected to the guide groove is fixedly connected to the inner wall of the guide block 607, and a square groove (as shown in FIG. Figure 7 As shown in FIG. 1 ), a square opening is provided on one side of the connection seat 3 close to the connection plate 602, and the square groove and the square opening are both adapted to the block 605. See FIG. Figure 3 The baffle plate 604 is V-shaped, and a conical hole with a small outside and a large inside is evenly opened on the side of the baffle plate 604 away from the water level gauge 8.

[0047] Through the rotational connection between the mounting seat 601 and the connecting block 608, the connecting plate 602 can be rotatably mounted on the bottom of the connecting seat 3, so that when the impact force borne by the baffle 604 fixedly connected to the bottom of the connecting plate 602 exceeds its maximum protection level, it can be rotated to reduce the impact area while achieving safe storage. The clamping block 605 penetrates the square opening on the connecting seat 3 and the clamping connection of the upper groove of the movable block 4 to achieve the water level gauge 8 and the baffle 604 The locking in the expanded state before use ensures that the water level gauge 8 and the baffle 604 can be located in the designated position for normal use. When the impact force borne by the baffle 604 exceeds its maximum protection level, the locking is released, and the water level gauge 8 and the baffle 604 can be transformed into the storage state under the drive of the driving component. The baffle 604 and the tapered holes evenly starting thereon can not only play a protective role, but also reduce the accumulation of a large amount of debris between the baffle 604 and the water level gauge 8 due to water flow blockage and sedimentation, as well as the Karman vortex street phenomenon. The sliding connection between the protrusion on the guide block 607 and the guide groove composed of annular grooves, spiral grooves and straight grooves on the fixed rod 603 can make the movable block 4 move at different positions to cause the connecting plate 602 to rotate at different angles, so as to achieve a good fit between the baffle 604 and the water level gauge 8.

[0048] The driving assembly includes a threaded rod 501 rotatably connected to the connecting seat 3, the thread angle of the outer side of the threaded rod 501 is sixty degrees, the movable block 4 is threadedly connected to the outer side of the threaded rod 501, and the outer side of the support rod 9 is fixedly connected with a toothed disc 502, and the threaded rod 501 passes through one end of the movable seat 2 and is fixedly connected with a gear 503, and the gear 503 and the toothed disc 502 are meshed with each other. A spring 504 is fixedly connected between the movable block 4 and the inner wall of the connecting seat 3, and a circular groove is opened on the side of the movable block 4 close to the movable seat 2, and the end of the spring 504 away from the movable seat 2 is fixedly connected to the inner wall of the circular groove, and the spring 504 is sleeved on the outer side of the threaded rod 501.

[0049] The threaded rod 501 with an outer thread angle of sixty degrees is connected to the movable block 4 through a thread, so that the movement of the movable block 4 can drive the threaded rod 501 to rotate, and the rotation of the threaded rod 501 can also drive the movable block 4 to move. Through the meshing connection between the threaded rod 501 and the gear 503, when the threaded rod 501 is driven to rotate by the movable block 4, the water level gauge 8 can be moved to the shore for easy protection and maintenance. When the movable block 4 is driven to move by the threaded rod 501, the water level gauge 8 is driven back into the water to continue working.

[0050] In combination with the above preferred embodiments, the working principle of the present invention is as follows:

[0051] As attached Figure 1 To Attachment Figure 6This is the state of the water level gauge 8 when it is located in the water for monitoring: the movable block 4 is located at the end of its stroke closest to the baffle 604, the clamping block 605 passes through the connecting seat 3 and is clamped with the upper groove of the movable block 4, the inner protrusion of the guide block 607 is located in the annular groove in the guide groove of the fixed rod 603, the mounting block 703 is in a vertical state under the support of the connecting rod 704, the water level gauge 8 is extended into the water to monitor the water level, the spring 2 707 is in the initial state, and the spring 1 504 is in an elastically stretched state.

[0052] The collision storage steps are as follows: when the speed of the river water in the river channel is too large or the impact force of the garbage on the baffle 604 exceeds the maximum protection level it can withstand, the baffle 604 drives the connecting plate 602 fixedly connected to its top to rotate around the fixed rod 603, and the rotation of the fixed rod 603 drives the clamping block 605 to disengage from the movable block 4. After the movable block 4 disengages from the clamping, it drives the guide block 607 and the slide seat 702 to move synchronously under the restoring elastic force of the spring 1 504. The movement of the slide seat 702 pulls the mounting block 703 to rotate in the storage seat 701 through the inclined connecting rod 704. When the water level gauge 8 fits with the bottom of the slide seat 702, the continued movement of the slide seat 702 drives the slider 706 to slide in the slide groove 705 and stretch the spring 2 707. When the slider 706 moves to fit with the inner wall of the slide groove 705, the water level gauge 8 rotates to the storage seat 701 for storage.

[0053] When the clamping block 605 is disengaged from the movable block 4, the fixed rod 603 rotates so that the protrusion in the guide block 607 moves to the connection between the annular groove and the spiral groove in the guide groove of the fixed rod 603. At this time, the movable block 4 driven by the spring 1 504 can slide in the spiral groove in the guide groove of the fixed rod 603 and push the fixed rod 603 to rotate. The rotating fixed rod 603 drives the connecting block 608 to rotate. The rotating connecting block 608 drives the connecting plate 602 and the baffle 604 to fit with the bottom of the storage seat 701. At this time, the protrusion in the guide block 607 moves to the connection between the spiral groove and the straight groove in the guide groove of the fixed rod 603, and the water level gauge 8 is just stored in the storage seat 701, so that the continued movement of the movable block 4 cannot affect the position state of the baffle 604 at this time.

[0054] The movable block 4 drives the threaded rod 501 to rotate during the movement, and the rotating threaded rod 501 drives the gear 503 fixed thereon to roll on the toothed disc 502, thereby realizing the rotation of the connecting seat 3 and the movable seat 2 on the outside of the support rod 9, so as to realize the rotation of the water level gauge 8 from the water surface to the shore, and the water level gauge 8 and the baffle 604 can continue to move after both are stored, until they move to the shore and are parallel to the water flow direction;

[0055] The rotation of the fixing rod 603 causes the torsion spring 610 to deform to achieve storage of elastic potential energy;

[0056] As attached Figure 7 To Attachment Fig.10 This is the state of the water level meter 8 after collision recovery. At this time, the monitoring personnel can inspect the water level meter 8 and decide whether the water level meter 8 continues to monitor;

[0057] The steps for converting the water level gauge 8 to the monitoring state are as follows: the operator pushes the connecting seat 3, so that the connecting seat 3 drives the threaded rod 501 to rotate through the meshing connection between the toothed disc 502 and the gear 503, and the rotating threaded rod 501 drives the movable block 4 to move and stretch the spring 504 to realize elastic potential energy storage. When the movable block 4 moves to fit the inner wall of the connecting seat 3 away from the inner wall of the end of the movable seat 2, the connecting block 608 drives the clamping block 605 to resume the clamping connection with the movable block 4 under the elastic reset force of the torsion spring 610. At this time, the inner protrusion of the guide block 607 moves to the connection between the annular groove and the spiral groove in the guide groove of the fixed rod 603, so that the fixed rod 603 can be rotated and reset, and the water level gauge 8 is in a vertical state and extends into the water.
