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 port and waterway hydraulic design. Background Art

[0002] A port is a transportation hub located along the coast of the sea, river, lake, or reservoir, with water-land transport equipment and conditions for safe entry, exit, and berthing of ships. There are waterways designed around the port for ships to navigate. The water level detection device used in the hydraulic design of the port channel is a detection device that detects the water level height, so as to achieve the effect of real-time detection and control of the water level. The water level detection devices currently on the market all use radar water level gauges for detection. Due to the requirements of some river water storage projects, the water level of some rivers varies greatly in different seasons. At this time, since the installation height of most radar water level gauges must be greater than 0.3m from the water surface, the staff needs to adjust the height of the radar water level gauge according to the height of the water level in the river.

[0003] A Chinese utility model patent with publication number CN216206821U discloses a water level detection device for a port and waterway hydraulic design, wherein the regulating device comprises a vertical groove, which is arranged on the surface of a vertical plate, a slider is slidably connected inside the vertical groove, a support plate is fixedly mounted on the surface of the slider, a horizontal plate is fixedly mounted on the surface of the support plate, a plurality of limiting holes are arranged on the side of the vertical plate, a slide groove is arranged on the side of the vertical plate, a displacement plate is fixedly mounted on the surface of the slide groove, two springs are fixedly mounted on the surface of the displacement plate, a pull plate is fixedly mounted on the end of the spring away from the displacement plate, and a limiting rod is fixedly mounted on the surface of the pull plate.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the above-mentioned device adjusts the height of the radar water level meter by sliding a slider set in the vertical groove. During this process, the staff needs to manually adjust the position of the slider while keeping the pull plate stable, which is inconvenient to operate and is not conducive to improving the staff's user experience. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a water level detection device for port and waterway hydraulic design.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a water level detection device for port and waterway hydraulic design, comprising a base and a mounting rod fixed on the upper surface of the base, a slide groove is provided on the side wall of the mounting rod, a slider is slidably arranged in the slide groove, a support rod is fixed on the upper surface of the slider, a detection rod is fixed on the side wall of the support rod, a radar water level gauge for detecting the water surface height is provided on the bottom surface of the detection rod, a threaded rod for fixing the slider is threadedly connected to the side wall of the slider, a fixing groove is provided on the inner wall of the slide groove, and a limiting component for limiting the slider is provided on the mounting rod.

[0007] By adopting the above technical solution, in order to detect and control the water level in real time, the staff needs to monitor the water level of the river with the help of a radar water level gauge. With the change of seasons, the water level of the river is prone to drastic changes. At this time, the staff needs to adjust the height of the radar water level gauge. At this time, the staff only needs to close the limit assembly and twist the threaded rod to move the slider downward under the action of gravity, and then move the slider to the lowest point. Further, the staff needs to open the limit assembly and slide the slider upward to move the slider upward. During this process, when the staff releases the slider, the slider remains stable under the action of the limit assembly, and the staff does not need to continue to apply a force to the slider to keep it stable. Subsequently, when the slider moves to the appropriate position, the staff only needs to release the slider and reset the threaded rod to keep the slider stable under the joint action of the limit assembly and the threaded rod.

[0008] Furthermore, a limiting groove is provided on the inner wall of the slide groove, and the limiting groove is slidably connected to the support rod.

[0009] Furthermore, the upper end of the limiting groove is open, and the upper end of the supporting rod extends outside the mounting rod.

[0010] By adopting the above technical solution, the support rod and the limiting groove are connected to each other, which improves the stability of the support rod, thereby facilitating improving the stability of the radar water level gauge.

[0011] Furthermore, a sliding groove is provided on the side wall of the slider, and the limit assembly includes a plurality of limit blocks evenly distributed on the inner wall of the fixed groove, a limit rod slidably arranged in the sliding groove, and a limit spring with one end fixed on the side wall of the limit rod away from the limit block, the other end of the limit spring is fixed on the inner wall of the sliding groove away from the limit block, a first inclined surface is provided on the edge where the bottom surface of the limit block intersects with the side wall close to the limit rod, and a second inclined surface is provided on the edge where the side wall of the limit rod close to the limit block intersects with the upper surface.

[0012] By adopting the above technical solution, when the staff needs to adjust the height of the radar water level meter, the staff needs to slide the limit rod and rotate the threaded rod, so that the limit rod and the limit block are separated from each other, and the threaded rod and the inner wall of the chute are separated from each other, so that the slider moves downward to the lowest point under the action of gravity. Subsequently, the staff needs to loosen the limit rod, so that the limit rod can be reset under the action of the limit spring, so that the limit block prevents the limit rod from moving downward. At this time, the staff needs to move the slider upward to adjust the height of the radar water level meter. When the height of the radar water level meter is adjusted to a suitable position, the staff only needs to loosen the slider so that the limit block can support the limit rod. Furthermore, the staff needs to rotate the threaded rod so that the threaded rod can be pressed against the inner wall of the chute, so that the slider remains stable.

[0013] Furthermore, a first seating groove is provided on the side wall of the limiting rod, a second seating groove is provided through the inner wall of the sliding groove, a seating rod is slidably arranged in the second seating groove, and a third inclined surface is provided on the edge where the side wall of the first seating groove away from the limiting block intersects with the side wall of the seating rod close to the second seating groove.

[0014] By adopting the above technical solution, when the staff needs to slide the limit rod, the staff only needs to press the placement rod to make the placement rod press against the third inclined surface, and then the limit rod moves away from the limit block under the action of the placement rod, thereby reducing the difficulty of the staff to move the limit rod.

[0015] Furthermore, an elastic rope is fixed on the side wall of the placement rod close to the first placement groove, and the other end of the elastic rope is fixed on the inner wall of the first placement groove.

[0016] By adopting the above technical solution, the probability of the placement rod and the second placement groove being separated from each other is reduced, thereby improving the stability of the device.

[0017] Furthermore, a support spring is fixed on the inner bottom wall of the slide groove, a slide plate is fixed on the other end of the support spring, and the slide plate is slidably connected to the slide groove.

[0018] By adopting the above technical solution, when the staff separates the limit rod and the limit block, the slider moves downward under the action of gravity. At this time, the slide plate and the support spring decelerate the slider, thereby reducing the probability of the slider directly hitting the bottom wall of the chute at full speed, thereby reducing the probability of damage to the radar water level meter.

[0019] Furthermore, a fixing block is fixed on the side wall of the threaded rod, and a plurality of fixing holes distributed at equal intervals are opened on the inner wall of the slide slot, and the fixing block and the fixing holes match each other.

[0020] By adopting the above technical solution, when the limit block supports the limit rod, the fixed block is opposite to one of the fixing holes. At this time, the staff only needs to rotate the threaded rod to connect the fixed block and the fixing hole to each other, so that the slider remains stable.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. In this application, in order to detect and control the water level in real time, the staff needs to monitor the water level of the river with the help of a radar water level gauge. With the change of seasons, the water level of the river is prone to drastic changes. At this time, the staff needs to adjust the height of the radar water level gauge. At this time, the staff only needs to close the limit assembly and turn the threaded rod to move the slider downward under the action of gravity, and then move the slider to the lowest point. Furthermore, the staff needs to open the limit assembly and slide the slider upward to move the slider upward. During this process, when the staff releases the slider, the slider remains stable under the action of the limit assembly, and the staff does not need to continue to apply force to the slider to keep it stable. Subsequently, when the slider moves to the appropriate position, the staff only needs to release the slider and reset the threaded rod to keep the slider stable under the joint action of the limit assembly and the threaded rod;

[0023] 2. In the present application, when the staff needs to adjust the height of the radar water level meter, the staff needs to slide the limit rod and rotate the threaded rod to separate the limit rod and the limit block, and to separate the threaded rod and the inner wall of the slide groove, so that the slider moves downward to the lowest point under the action of gravity. Afterwards, the staff needs to loosen the limit rod so that the limit rod can be reset under the action of the limit spring, so that the limit block prevents the limit rod from moving downward. At this time, the staff needs to move the slider upward to adjust the height of the radar water level meter. When the height of the radar water level meter is adjusted to the appropriate position, the staff only needs to loosen the slider so that the limit block can support the limit rod. Furthermore, the staff needs to rotate the threaded rod so that the threaded rod can be pressed against the inner wall of the slide groove, so that the slider remains stable;

[0024] 3. In this application, when the staff separates the limit rod and the limit block, the slider moves downward under the action of gravity. At this time, the slide plate and the support spring decelerate the slider, thereby reducing the probability of the slider directly hitting the bottom wall of the chute at full speed, thereby reducing the probability of damage to the radar water level meter.

[0033] like Figure 1-6 As shown, the embodiment of the present application discloses a water level detection device for port and waterway hydraulic design, including a base 1, a mounting rod 11, a slider 21, a support rod 3, a detection rod 31, a radar water level gauge 4, a threaded rod 41, a limit assembly 5, a placement rod 7, an elastic rope 8, a support spring 81, a slide plate 82 and a fixing block 83.

A slide groove 2 is provided on the side wall of the mounting rod 11, and the slider 21 is a rectangular block structure, and the slider 21 is slidably arranged in the slide groove 2. The support rod 3 is a rectangular rod-shaped structure, and the support rod 3 is fixed to the upper surface of the slider 21. The detection rod 31 is a rectangular rod-shaped structure, and the detection rod 31 is fixed to the side wall of the support rod 3. The radar water level gauge 4 is arranged on the bottom surface of the detection rod 31 for detecting the water level. The threaded rod 41 is threadedly connected to the side wall of the slider 21 for fixing the slider 21.

[0034] A fixing groove 42 is provided on the inner wall of the slide groove 2, a sliding groove 43 is provided on the side wall of the slider 21, and a limiting assembly 5 is provided on the mounting rod 11 for limiting the slider 21. The limiting assembly 5 includes a limiting block 51, a limiting rod 52, and a limiting spring 53.

One end of the limiting spring 53 is fixed to the side wall of the limiting rod 52 away from the limiting block 51 , and the other end of the limiting spring 53 is fixed to the inner wall of the sliding groove 43 away from the limiting block 51 .

[0035] When the staff needs to adjust the height of the radar water level meter 4, the staff needs to slide the limit rod 52 and rotate the threaded rod 41, so that the limit rod 52 and the limit block 51 can be separated from each other, and the threaded rod 41 and the inner wall of the chute 2 can be separated from each other, so that the slider 21 moves downward to the lowest point under the action of gravity. Subsequently, the staff needs to loosen the limit rod 52, so that the limit rod 52 can be reset under the action of the limit spring 53, so that the limit block 51 prevents the limit rod 52 from moving downward. At this time, the staff needs to move the slider 21 upward to adjust the height of the radar water level meter 4. When the height of the radar water level meter 4 is adjusted to a suitable position, the staff only needs to loosen the slider 21, so that the limit block 51 can support the limit rod 52. Further, the staff needs to rotate the threaded rod 41, so that the threaded rod 41 can be pressed against the inner wall of the chute 2, so that the slider 21 remains stable.

[0036] In order to improve the stability of the support rod 3, thereby improving the stability of the radar water level meter 4, a limit groove 6 is opened on the inner wall of the slide 2, the limit groove 6 is slidably connected to the support rod 3, the upper end of the limit groove 6 is open, and the upper end of the support rod 3 extends to the outside of the mounting rod 11.

[0038] When the staff needs to slide the limit rod 52, the staff only needs to press the placement rod 7 to make the placement rod 7 press against the third inclined surface 71, and then the limit rod 52 moves away from the limit block 51 under the action of the placement rod 7, thereby reducing the difficulty of the staff to move the limit rod 52.

[0039] One end of the elastic cord 8 is fixed to the side wall of the placement rod 7 near the first placement groove 61, and the other end of the elastic cord 8 is fixed to the inner wall of the first placement groove 61. The elastic cord 8 reduces the probability of the placement rod 7 and the second placement groove 62 being separated from each other, thereby improving the stability of the device.

[0040] One end of the support spring 81 is fixed on the inner bottom wall of the slide slot 2 . The slide plate 82 is a rectangular plate-shaped structure. The slide plate 82 is fixed on the other end of the support spring 81 , and the slide plate 82 is slidably connected to the slide slot 2 .

[0041] When the staff separates the limit rod 52 from the limit block 51, the slider 21 moves downward under the action of gravity. At this time, the slide plate 82 and the support spring 81 decelerate the slider 21, thereby reducing the probability of the slider 21 directly hitting the bottom wall of the chute 2 at full speed, thereby reducing the probability of the radar water level meter 4 being damaged.

[0042] The fixing block 83 is a round block structure, and is fixed on the side wall of the threaded rod 41 . A plurality of fixing holes 9 distributed at equal intervals are formed on the inner wall of the slide groove 2 , and the fixing block 83 and the fixing holes 9 match each other.

[0043] When the limiting block 51 supports the limiting rod 52 , the fixing block 83 is directly opposite to one of the fixing holes 9 . At this time, the staff only needs to rotate the threaded rod 41 to connect the fixing block 83 and the fixing hole 9 to each other, so that the slider 21 remains stable.

[0044] The use principle of a water level detection device for a port and waterway hydraulic design in this embodiment is as follows: in order to detect and control the water level in real time, the staff needs to monitor the water level of the river with the help of a radar water level gauge 4. With the change of seasons, the water level of the river is prone to drastic changes. At this time, the staff needs to adjust the height of the radar water level gauge 4. At this time, the staff only needs to close the limit assembly 5 and twist the threaded rod 41 to move the slider 21 downward under the action of gravity, thereby moving the slider 21 to the lowest point. Further, the staff needs to open the limit assembly 5 and slide the slider 21 upward to move the slider 21 upward. In this process, when the staff releases the slider 21, the slider 21 remains stable under the action of the limit assembly 5, and the staff does not need to continue to apply a force to the slider 21 to keep it stable. Subsequently, when the slider 21 moves to a suitable position, the staff only needs to release the slider 21 and reset the threaded rod 41 to keep the slider 21 stable under the joint action of the limit assembly 5 and the threaded rod 41.
