Background technique

The dam is the general term for dikes and dams, and it also refers to buildings and structures that are waterproof and water-blocking. For example, it is necessary to step up the construction of the dam to prevent water from being damaged. There are two main types of modern dams: earth-rock dams and concrete dams. In recent years, large dams have been constructed using high-tech reinforced concrete.

The water level refers to the elevation of the free surface of water bodies such as rivers, lakes, oceans and reservoirs from the fixed base. The role of water level measurement is to provide materials with separate use value for water conservancy, water transport, flood control and flood control, and to provide indirect use data for other hydrological data.

Preferably, the height of the graduated tubule is 100 m.

Working principle: When people need to measure the water level of the dam, people push the cart to reach the place where the water level measurement is needed near the dam, and people stop pushing the cart. The first electric push rod is extended to drive the rack to move downward, the rack drives the second fixed plate to move downward, and the second fixed plate drives the scale tube to move downward During the downward movement of the rack, the gear is meshed with the rack, so that the gear swings downward, and the gear drives the block to move upward, so that the drum rotates, and the rotating frame is rotated, and the scale pipe moves downward to contact the river. At the bottom of the embankment, the first electric push rod stops working. Because of the scale on the scale tube, the water level can be measured by the height of the river entering the scale tube. At this time, the river enters the scale tube through the small hole, and the first electric push rod is shortened to drive the rack to move upward, the rack drives the second fixed plate to move upward, and the second fixed plate drives the scale tube to move upward, and the rack moves upward. During the process, since the gear meshes with the rack, the gear moves upward, and the gear drives the block to move downward, so that the drum rotates to drive the placing frame to rotate, and when the scale small tube moves up to the proper position, the first electric push rod stops working. The starting cylinder is shortened, and the lower end of the scale tube is tilted to the upper right. When the scale tube is tilted to the proper position, the cylinder stops working, the second electric push rod is started to extend, and the placing frame is moved to the right. When the placing frame moves to the right to the right At the left side of the scale tube, the second electric push rod stops working. At this time, the river water remaining in the scale tube falls into the placement frame through the small hole, so that the right end of the pH test paper located in the placement frame is wetted, and people can measure The pH of the river water. Start cylinder extension, drive the scale tube to reset, start the second electric push rod to shorten, drive the reset frame to reset, start the first electric push rod to work, and drive the rack to reset.

Because it also includes a rubber mat, it also includes a rubber mat. The bottom of the box is provided with a rubber mat. The pH test paper is placed on the rubber mat, so the pH test paper can be prevented from being damaged when measuring the pH value of the river water.

Since the board is also included, the left side of the cart is provided with a placing board, so that people can place items such as water cups on the placing board during the measurement of the water level.

Because the third electric push rod and the weight block are further included, the bottom of the cart is provided with a third electric push rod, the third electric push rod is located at the left side of the through hole, and the lower end of the third electric push rod is connected with the weight block. During the process of measuring the water level, the third electric push rod is started to extend, and the weight block is moved downward. When the weight block contacts the ground, the third electric push rod stops working, so the cart can be prevented from measuring the water level. Move left and right during the process.

Because the material of the bracket is Q235 steel, Q235 steel is less prone to rust and has high toughness, so it can extend the service life of the bracket.

(3) beneficial effects

The invention achieves the effects that the measurement result is accurate, the measurement difficulty is small, the observation is convenient, and the workload of the people is greatly reduced.

The scale tube 3 has a cylindrical shape.

The height of the graduated tube 3 is 100 m.

Working principle: When people need to measure the water level of the dam, the person pushes the cart 4 to the place where the water level measurement is needed near the dam, and the person stops pushing the cart 4. The first electric push rod 19 is extended to drive the rack 22 to move downward, the rack 22 drives the second fixed plate 23 to move downward, and the second fixed plate 23 drives the scale small tube 3 to move downward, and the rack 22 is downward. During the movement, since the gear 11 meshes with the rack 22, the gear 11 swings downward, and the gear 11 drives the block 13 to move upward, so that the drum 15 rotates to drive the placing frame 5 to rotate, and when the scale tube 3 moves downward, the value is contacted. At the bottom of the river bank, the first electric push rod 19 stops working, and since the graduated small tube 3 has a scale, the height of the river entering through the scale small tube 3 allows one to measure the water level. At this time, the river enters the scale tube 3 through the small hole 26, and the first electric push rod 19 is shortened to drive the rack 22 to move upward, the rack 22 drives the second fixed plate 23 to move upward, and the second fixed plate 23 drives the scale tube 3 upward. Moving, during the upward movement of the rack 22, since the gear 11 meshes with the rack 22, the gear 11 moves upward, and the gear 11 drives the block 13 to move downward, so that the drum 15 rotates to drive the placing frame 5 to rotate. When the small tube 3 is moved up to the proper position, the first electric push rod 19 stops working. The starting cylinder 24 is shortened, and the lower end of the scale small tube 3 is inclined to the upper right. When the scale small tube 3 is tilted to the proper position, the cylinder 24 stops working, the second electric push rod 7 is started to be extended, and the placing frame 5 is moved to the right when placed. The frame 5 is moved to the right to the left position of the scale tube 3, and the second electric push rod 7 stops working. At this time, the river water remaining in the scale tube 3 falls into the placement frame 5 through the small hole 26, and will be placed in the placement frame. The pH of the river water can be measured by soaking the right end of the pH test paper 6 in 5. The starting cylinder 24 is extended, the scale tube 3 is reset, the second electric push rod 7 is started to be shortened, the placing frame 5 is reset, and the first electric push rod 19 is activated to drive the rack 22 to be reset.

Since the rubber pad 27 is further included, a rubber pad 27 is further included, and a rubber pad 27 is disposed at the bottom of the placing frame 5, and the pH test paper 6 is placed on the rubber pad 27, so that the pH can be prevented when measuring the pH of the river water. Test strip 6 is damaged.

Since the placement plate 28 is also included, the placement plate 28 is disposed on the left side of the cart 4. Therefore, in the process of measuring the water level, one can place an item such as a water cup on the placement board 28.

Since the third electric push rod 29 and the weight block 30 are further included, the bottom of the cart 4 is provided with a third electric push rod 29, the third electric push rod 29 is located at the left side of the through hole 2, and the lower end of the third electric push rod 29 A weight block 30 is connected. During the measurement of the water level, the third electric push rod 29 is activated to extend, and the weight block 30 is moved downward. When the weight block 30 contacts the ground 1, the third electric push rod is connected. 29 stops working, so it is possible to prevent the cart 4 from moving left and right during the measurement of the water level.

Because the material of the bracket 16 is Q235 steel, the Q235 steel is less prone to rust and has high toughness, so the service life of the bracket 16 can be extended.
