Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a water level measuring device for water conservancy projects. Background Technology

[0002] Water conservancy projects include water level observation, which includes riverbed changes, flow momentum, flow direction, flood diversion, ice conditions, aquatic plants, waves, wind direction, wind force, water surface undulation, water temperature and water level changes. Water level measurement devices are required when measuring water levels.

[0003] In existing technologies, when measuring water levels, the graduated measuring rope is usually placed manually. When the worker feels the weight in their hand lighten, it indicates that the weight at the bottom of the measuring rope has reached the riverbed, and the line is stopped to read the scale. In this process, manually placing the measuring rope is inefficient, and the worker may not be able to detect the weight reaching the riverbed in time due to unstable hand strength, resulting in low measurement accuracy. On the other hand, the measuring rope is inconvenient to wind up and is not convenient to store and carry.

[0004] To address this issue, a water level measuring device for water conservancy projects is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a water level measuring device for water conservancy projects, comprising: a housing, a transmission chamber formed inside one side of the housing, connecting shafts connected to both sides of the housing via bearings, extension rods connected to the other ends of the two connecting shafts, an auxiliary rod assembly disposed between the opposite sides of the other ends of the two extension rods, limit blocks connected to both sides of the housing, pressure sensors mounted on the top of the two limit blocks, two mounting plates connected to one side of the housing, an adjusting rod disposed between the opposite sides of the two mounting plates, a control terminal mounted on the top of the housing, a transmission assembly disposed at the bottom of the inner cavity of the housing, a winding rod connected to the inside of the housing via bearings, two baffles sleeved on the surface of the winding rod, and a graduated measuring rope wound around the surface of the winding rod.

[0007] In a preferred embodiment, the auxiliary rod assembly includes an auxiliary rod connected between opposite sides of two extension rods. The auxiliary rod has four limiting grooves on its surface and a bearing sleeve on its surface. The bearing has four limiting slide plates connected to its inner side, and the four limiting slide plates are movably embedded in the inner side of the four limiting grooves. The bearing has a sleeve sleeve on its surface, and the sleeve has a limiting groove on its surface.

[0008] In a preferred embodiment, the surface of the adjusting rod is provided with four limiting grooves, and a sleeve is movably fitted onto the surface of the adjusting rod. The inner side of the sleeve is connected to four limiting slide plates.

[0009] In a preferred embodiment, the four limiting slide plates are respectively movably embedded inside the four limiting slide grooves. The surface of the sleeve is connected to a limiting plate, and the surface of the limiting plate has a through hole. The surface of the scale measuring rope moves through the inside of the through hole.

[0010] In a preferred embodiment, the transmission assembly includes a sealed housing, which is installed at the bottom of the inner cavity of the housing. A battery and a reversing motor are installed at the bottom of the inner cavity of the sealed housing. The output end of the reversing motor is connected to a sprocket through a bearing on one side of the transmission chamber.

[0011] In a preferred embodiment, one end of the winding rod passes through the transmission chamber and is connected to a second sprocket, and a chain is fitted onto the surface of the second sprocket and the first sprocket.

[0012] In a preferred embodiment, the other end of the scale measuring rope is connected to a weight block, and a drainage groove is provided on one side of the housing.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. This utility model electrically connects the storage battery, control terminal, and forward / reverse motor. When used for water level measurement in hydraulic engineering projects, workers travel by boat to the middle of the river where the measurement is to be performed. The device is placed on the deck of the small boat, and the auxiliary rod is manually flipped to place two extension rods on top of two pressure sensors. The two extension rods extend the auxiliary rods out of the boat hull. By operating the control terminal, a corresponding weight measurement range is set according to the weight of the extension rods, auxiliary rods, and the weight block. Then, holding the weight block, a portion of the graduated measuring rope is pulled out, and the surface of the graduated measuring rope is placed inside the limiting groove. The control terminal is operated, and the forward / reverse motor operates, causing the weight block to slowly descend into the river. When the pressure sensor detects a value lower than the set weight range, the forward / reverse motor stops, indicating that the weight block has reached the riverbed. At this point, the scale on the graduated measuring rope is read, completing the measurement. This setup facilitates rapid water level measurement, improves measurement accuracy, and increases work efficiency.

[0015] 2. After the measurement is completed, the operator controls the control terminal to rotate the forward and reverse motors in the opposite direction to wind up the scale measuring rope. During the winding process, the operator can adjust the winding position of the scale measuring rope on the surface of the winding rod by moving the second sleeve until the top of the weight block is in contact with the surface of the limiting plate to complete the winding. Then, the auxiliary rod is flipped upwards, and the first sleeve is held to move and carry the device. With this setting, the scale measuring rope can be wound up quickly, making it easy to carry and store the device. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a water level measuring device for water conservancy projects, comprising: a housing 1, a transmission chamber 101 inside one side of the housing 1, connecting shafts 2 connected to both sides of the housing 1 via bearings, extension rods 3 connected to the other ends of the two connecting shafts 2, an auxiliary rod assembly 4 disposed between the opposite sides of the other ends of the two extension rods 3, limit blocks 5 connected to both sides of the housing 1, pressure sensors 6 mounted on the top of the two limit blocks 5, two mounting plates 7 connected to one side of the housing 1, an adjusting rod 8 connected between the opposite sides of the two mounting plates 7, a control terminal 9 mounted on the top of the housing 1, a transmission assembly 10 disposed at the bottom of the inner cavity of the housing 1, a winding rod 11 connected to the inside of the housing 1 via bearings, two baffles 12 sleeved on the surface of the winding rod 11, and a scale measuring rope 13 wound around the surface of the winding rod 11.

[0024] Specifically: the auxiliary rod assembly 4 assists in the winding and unwinding of the scale measuring rope 13; the pressure sensor 6 weighs the extension rod 3; when the load block 14 reaches the riverbed, the pressure sensor 6 detects that the weight of the extension rod 3 has decreased; the adjusting rod 8 is used to adjust the winding position of the scale measuring rope 13 on the surface of the winding rod 11; the control terminal 9 is used to control the pressure sensor 6 and the forward and reverse motor 1003; and the transmission assembly 10 winds and unwinds the scale measuring rope 13 through the winding rod 11.

[0025] In one embodiment, the auxiliary rod assembly 4 includes an auxiliary rod 401 connected between the opposite sides of the two extension rods 3. The surface of the auxiliary rod 401 is provided with four limiting slide grooves 402. The surface of the auxiliary rod 401 is fitted with a bearing 403. The inner side of the bearing 403 is connected with four limiting slide plates 404. The four limiting slide plates 404 are respectively movably embedded in the inner side of the four limiting slide grooves 402. The surface of the bearing 403 is fitted with a sleeve 405. The surface of the sleeve 405 is provided with a limiting groove 406.

[0026] Specifically: the limiting slide groove 402 and the limiting slide plate 404 cooperate to limit the inner side of the bearing 403, so that the bearing 403 can only slide along the surface of the auxiliary rod 401, the auxiliary sleeve 405 of the bearing 403 rotates, and the limiting groove 406 limits the scale measuring rope 13 to prevent the weight block 14 from falling off the surface of the sleeve 405.

[0027] In one embodiment, the surface of the adjusting rod 8 is provided with four limiting grooves 801, and the surface of the adjusting rod 8 is movably fitted with a sleeve 802, and the inner side of the sleeve 802 is connected to four limiting slide plates 803.

[0028] Specifically: Limiting groove 801 and limiting slide plate 803 limit sleeve 802, so that sleeve 802 can only slide along the surface of adjusting rod 8. Sleeve 802 is used to adjust the winding position of scale measuring rope 13 on the surface of winding rod 11.

[0029] In one embodiment, four limiting slide plates 803 are respectively movably embedded inside the four limiting slide grooves 801, the surface of the sleeve 802 is connected to a limiting plate 804, the surface of the limiting plate 804 is provided with a through hole 805, and the surface of the scale measuring rope 13 movably passes through the inside of the through hole 805.

[0030] Specifically: the limiting plate 804 and the through hole 805 limit the winding and unwinding ends of the scale measuring rope 13.

[0031] In one embodiment, the transmission assembly 10 includes a sealed housing 1001, which is installed at the bottom of the inner cavity of the housing 1. A battery 1002 and a reversible motor 1003 are installed at the bottom of the inner cavity of the sealed housing 1001. The output end of the reversible motor 1003 is connected to a sprocket 1004 through a bearing on one side of the transmission chamber 101.

[0032] Specifically: the top of the sealed enclosure 1001 is sloping to allow water droplets to slide off; the battery 1002 provides power to the forward and reverse motor 1003; and both one side of the battery 1002 and one side of the sealed enclosure 1001 have corresponding charging ports to facilitate charging of the battery 1002.

[0033] In one embodiment, one end of the winding rod 11 passes through one side of the transmission chamber 101 and is connected to a second sprocket 1101. A chain 1005 is fitted onto the surfaces of the second sprocket 1101 and the first sprocket 1004.

[0034] Specifically: the forward and reverse motor 1003 drives the first sprocket 1004 to rotate, which in turn drives the second sprocket 1101 to rotate synchronously through the chain 1005, thereby causing the winding rod 11 to wind up and unwind the scale measuring rope 13.

[0035] In one embodiment, the other end of the scale measuring rope 13 is connected to a weight block 14, and a drainage groove 15 is provided on one side of the housing 1.

[0036] Specifically: the weight block 14 is used as a counterweight to facilitate the bottom of the scale measuring rope 13 sinking to the bottom of the water for measuring the depth of the river; the drainage trough 15 is used to drain the river water carried by the scale measuring rope 13 after use.

[0037] Working principle: The battery 1002 is electrically connected to the control terminal 9 and the forward / reverse motor 1003. When used for water level measurement in water conservancy projects, the staff travels by boat to the middle of the river where the measurement is to be performed, places the device on the deck of the small boat, and manually flips the auxiliary rod 401 to place the two extension rods 3 on top of the two pressure sensors 6. The two extension rods 3 extend the auxiliary rod 401 out of the hull. By operating the control terminal 9, the corresponding weight measurement range is set according to the weight of the extension rods 3, auxiliary rods 401, and weight block 14. Then, holding the weight block 14, part of the graduated measuring rope 13 is pulled out, and the surface of the graduated measuring rope 13 is placed inside the limit groove 406. By operating the control terminal 9, the forward / reverse motor 1003 works, and the weight block 14 slowly enters the river. When the pressure sensor 6 detects a value lower than the target value, the measurement range is determined. When the set weight range is reached, the forward and reverse motor 1003 stops working, indicating that the load block 14 has reached the riverbed. At this time, the scale on the surface of the scale measuring rope 13 is read to complete the measurement. This setting facilitates quick water level measurement, improves measurement accuracy, and increases work efficiency. After the measurement is completed, the operator controls the control terminal 9, and the forward and reverse motor 1003 rotates in the opposite direction to wind up the scale measuring rope 13. During the winding process, the operator can adjust the winding position of the scale measuring rope 13 on the surface of the winding rod 11 by moving the second sleeve 802 until the top of the load block 14 is in contact with the surface of the limiting plate 804 to complete the winding. Then, the auxiliary rod 401 is flipped upwards, and the first sleeve 405 is held for carrying. This setting allows for quick winding of the scale measuring rope 13, facilitating the carrying and storage of the device.

However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
