[0001] The utility model relates to the technical field of water conservancy projects, in particular to a water level height surveying device for water conservancy projects. Background Art

[0002] Water is a valuable resource that is indispensable to human production and life. The construction of water conservancy projects can control water flow, prevent floods and waterlogging, and regulate and distribute water to meet people's needs for water resources in life and production. Water level survey is an important part of water conservancy project inspection. Water level height survey is to monitor the depth of water bodies intercepted by dams and other water conservancy projects.

[0003] Existing water level surveys for water conservancy projects use sonar detectors on board ships to conduct survey operations. However, for surveys in the middle of narrow rivers, it is difficult for ships to enter, but it is also difficult to measure from the shore. In addition, the existing water level survey equipment has surface currents that affect the stability of the surveying instrument, and the sonar survey direction is easily changed, resulting in inaccurate measurement results. Utility Model Content

[0004] The utility model aims to provide a water level survey device for a hydraulic project, so as to solve the problem in the above background technology that the existing hydraulic project water level survey is carried out by a ship using a sonar detector for surveying, but for the survey condition in the middle of a narrow river channel, it is difficult for the ship to enter, but it is also difficult to measure from the shore.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water level survey device for a water conservancy project, including a sonar detector, and also including a lifting and limiting base, a lifting column, a lifting and limiting top seat, a drone connecting seat and a water level lifting mechanism, the water level lifting mechanism includes a movable frame, an annular sleeve, a float fixing seat, a connecting rod, and a float, an annular sleeve is arranged on the side of the movable frame, a float fixing seat is arranged on the side of the annular sleeve, a connecting rod is arranged on the side of the float fixing seat, and a float is arranged at one end of the connecting rod.

[0006] Preferably, the annular sleeve is sleeved outside the movable frame, and the float fixing seat is rotatably connected to the movable frame through the annular sleeve.

[0007] Preferably, the floats and connecting rods are arranged in multiple groups around the float fixing seat.

[0008] Preferably, a track is provided on the side of the lifting column, and the water level lifting mechanism also includes a connecting frame, a roller seat, and a roller. The roller seat and the track are arranged in a one-to-one correspondence. The connecting frame is a square ring, and the roller seat is fixedly connected to the connecting frame in a groove on the inner side of the connecting frame. The connecting frame and the lifting column are slidably connected.

[0009] Preferably, two sonar detectors are fixedly connected to the axial side of the float fixing seat, and the sonar detectors are symmetrically arranged about the center of the float fixing seat.

[0010] Preferably, the drone connecting seat includes a drone fixing plate, a clamping plate, and an anti-slip pad. The drone fixing plate is arranged above the lifting limit top seat, the side of the drone fixing plate is connected to the clamping plate, and an anti-slip pad is arranged on the inner side of the clamping plate close to the drone fixing plate.

[0011] Preferably, two groups of the clamping plates and anti-skid pads are arranged on both sides of the drone fixing plate, the clamping plates and anti-skid pads are arranged symmetrically about the drone fixing plate, and the anti-skid pads are adhesively connected to the clamping plates.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model, through the arrangement of the floating balls and the movable frame, can directly bring in the drone to conduct the survey in the narrow river conditions without taking a boat, which is more practical; when there are waves on the water surface, the water level changes constantly, and there is no need to repeatedly adjust the height of the drone. The four groups of floating balls float on the water surface. Under the action of buoyancy, the height of the four groups of floating balls changes with the change of water level. The movable frame is driven by the floating balls, and the roller seats in the four directions inside the movable frame are driven by the rollers to slide up and down in the track of the lifting column, thereby driving the height of the movable frame to change, which can ensure that the sonar detector on the bottom of the movable frame is always on the water surface, and the water level survey is more accurate;

[0014] 2. The utility model sets an annular sleeve and four groups of floating balls, so that the movable frame can be at the average height of the water surface within the horizontal range of the four groups of floating balls, and the movable frame can be fine-tuned in the horizontal parallel direction, so that the sonar detector can be as close to the vertical downward survey as possible, and obtain more accurate water level height data. With the direction of the water flow, the annular sleeve can drive the four groups of floating balls to rotate. The rotation process reduces the resistance of the device to the water flow, and at the same time reduces the impact of the water flow on the device, which increases the stability of the device and makes the survey results more accurate.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6 The utility model provides an embodiment: a water level survey device for a water conservancy project, including a sonar detector 7, a lifting limit base 1, a lifting column 2, a lifting limit top seat 4, a drone connection seat 5 and a water level lifting mechanism 6, the water level lifting mechanism 6 includes a movable frame 601, an annular sleeve 605, a float fixing seat 606, a connecting rod 608, and a float 609. The annular sleeve 605 is arranged on the side of the movable frame 601, the float fixing seat 606 is arranged on the side of the annular sleeve 605, the connecting rod 608 is arranged on the side of the float fixing seat 606, and the float 609 is arranged at one end of the connecting rod 608.

[0024] The drone connecting seat 5 includes a drone fixing plate 501, a clamping plate 502, and an anti-skid pad 503. The drone fixing plate 501 is arranged above the lifting limit top seat 4, the side of the drone fixing plate 501 is connected to the clamping plate 502, and the anti-skid pad 503 is arranged on the inner side of the clamping plate 502 close to the drone fixing plate 501. Two groups of clamping plates 502 and anti-skid pads 503 are arranged on both sides of the drone fixing plate 501, and the clamping plate 502 and the anti-skid pads 503 are arranged symmetrically about the drone fixing plate 501, and the anti-skid pads 503 are bonded to the clamping plate 502. The clamping plate 502 is fixedly connected to the drone fixing plate 501 by a spring inside the drone fixing plate 501. Before the device is used to measure the water level, the drone fixing plate 501 is connected to the drone by screws, and the clamping plates 502 are pulled to both sides to increase the distance between the two sets of clamping plates 502, clamping the lifting limit top seat 4, and the protruding edge of the clamping plate 502 falls into the groove of the lifting limit top seat 4. The clamping plate 502 is loosened, and the drone and the lifting limit top seat 4 are fixedly connected under the action of the spring. The anti-skid pad 503 increases the friction between the lifting limit top seat 4 and the clamping plate 502, so that the drone can firmly fix the lifting limit top seat 4 during flight and is not easy to fall. Using the existing drone technology, combined with this device, water level height can be surveyed in various situations, especially for the working conditions of surveying in the middle of a narrow river channel.

[0025] There are two sonar detectors 7 fixedly connected to the axial side of the float fixing seat 606, and the sonar detectors 7 are symmetrically arranged about the center of the float fixing seat 606. The sonar detector 7 is an existing technology, and the detection direction of the sonar detector 7 is downward. After the drone is fixedly connected, the center of gravity of the device is on the geometric center axis of the entire device. When the drone is hoisted, the lifting column 2 basically maintains a vertical state, thereby ensuring the vertical downward survey of the sonar detector 7. The sonar detector 7 transmits sound wave signals underwater and then receives the reflected sound wave signals, thereby obtaining the height from the surface movable frame 601 to the bottom of the water, completing the water level survey. The simultaneous survey of two groups of sonar detectors 7 can improve the accuracy of the measurement results.

[0026] There are multiple groups of floating balls 609 and connecting rods 608 around the floating ball fixing seat 606. The arrangement of four groups of floating balls 609 enables the movable frame 601 to be at the average height of the water surface within the horizontal range of the four groups of floating balls 609, and fine-tune the movable frame 601 in the horizontal parallel direction, so that the sonar detector 7 can be as close to the vertical downward survey as possible, and obtain more accurate water level height data.

[0027] The side of the lifting column 2 is provided with a track 3, and the water level lifting mechanism 6 includes a connecting frame 602, a roller seat 603, and a roller 604. The roller seat 603 is arranged one by one with the track 3. The connecting frame 602 is a square ring. The roller seat 603 is fixedly connected to the connecting frame 602 in the inner groove. The connecting frame 602 is slidably connected to the lifting column 2. The drone brings the device above the water level to be surveyed, and the lifting column 2 is inserted into the water. Four groups of floating balls 609 float on the water surface. Under the action of buoyancy, the height of the four groups of floating balls 609 changes with the change of water level. The movable frame 601 is driven by the floating balls 609. The roller seats 603 in four directions inside the movable frame 601 are driven by the rollers 604 to slide up and down in the track 3 of the lifting column 2, thereby driving the height of the movable frame 601 to change, ensuring that the sonar detector 7 on the bottom of the movable frame 601 is always on the water surface. The sliding connection of the roller 604 reduces the resistance when the movable frame 601 is raised and lowered, making the float 609 more sensitive to changes in water level, thereby ensuring that the water level height survey data is more accurate.

[0028] The water level lifting mechanism 6 includes a movable frame 601, an annular sleeve 605, a floating ball fixing seat 606, a connecting rod 608, and a floating ball 609. The annular sleeve 605 is sleeved outside the movable frame 601, and the floating ball fixing seat 606 is rotatably connected to the movable frame 601 through the annular sleeve 605. Following the direction of the water flow, the annular sleeve 605 can drive the four groups of floating balls 609 to rotate. The rotation process reduces the resistance of the device to the water flow, and at the same time reduces the impact of the water flow on the device, thereby increasing the stability of the device and making the survey results more accurate.

Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
