Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, and particularly relates to a measuring device for the diameter of a water conservancy ditch. Background Technique

[0002] Water conservancy engineering is a discipline and technical field involving the development, management, protection of water resources, and flood control and drainage. It includes the design, construction, and maintenance of various facilities such as dams, reservoirs, irrigation systems, drainage systems, and flood control dikes to ensure the efficient use of water resources, prevent flood disasters, improve the water environment, and ensure water supply safety.

[0003] During the construction of water conservancy projects, it is usually necessary to excavate ditches and then lay water conservancy pipelines. After the ditches are excavated and formed, it is necessary to measure them to ensure that their widths meet the construction requirements. Currently, a tape measure is used for measurement. When using a tape measure, two people are required to operate. One person holds one end and is located on both sides of the ditch width direction respectively. This operation method not only increases the labor cost but also may cause errors due to the cooperation problem between personnel during the measurement process, greatly reducing the project progress and being unfavorable for the rapid development of the project.

[0006] A measuring device for the diameter of a water conservancy ditch includes a hollow plate. A telescopic plate is inserted into the interior of the hollow plate. A through groove is formed on the outer surface of the hollow plate along its length direction. A pointer is installed on the outer surface of the telescopic plate and is arranged in the through groove. Scale lines are arranged on the outer surface of the hollow plate along its length direction. First side blocks and second side blocks are respectively installed on the opposite surfaces of the hollow plate and the telescopic plate. A rotating shaft is inserted through and rotatably installed in the interiors of the first side blocks and the second side blocks. Contact plates are installed at both ends of the rotating shaft. Arc-shaped blocks are installed on the outer surfaces of the first side blocks and the second side blocks. Two insertion holes are formed in the inner wall of the arc-shaped block, and the included angle between the two insertion holes is 90 degrees. A first fixing mechanism that is inserted and matched with the insertion hole is arranged inside one of the contact plates.

[0007] It can be seen that by respectively pressing the contact plates on both sides against both sides of the inner wall of the ditch, the measured value can be quickly read through the corresponding position of the pointer and the scale line, achieving the purpose of quickly measuring the diameter of the ditch. One person can complete the measurement. And because the contact plates on both sides are pressed against the inner wall of the ditch to play a limiting role, the hollow plate and the telescopic plate can be kept perpendicular to the ditch side wall, so the measurement error can be reduced, the measurement accuracy can be improved, and it is beneficial to the rapid development of the project.

[0008] Furthermore, the first fixing mechanism includes a plug rod disposed inside the abutting plate. A slider is slidably mounted on the outer surface of the abutting plate, and the slider is connected to the plug rod. A first spring is disposed inside the abutting plate, and two ends of the first spring respectively abut against the inner wall of the abutting plate and the plug rod.

[0009] Furthermore, a sliding rod is installed inside the hollow plate along its length direction. A sliding sleeve is sleeved on the outer surface of the sliding rod. The end of the sliding sleeve is connected to the telescopic plate. A second spring is sleeved on the outer surface of the sliding rod, and two ends of the second spring respectively abut against the inner wall of the hollow plate and the sliding sleeve. A through hole is formed on the surface of the hollow plate, and a second fixing mechanism which is inserted and matched with the through hole is disposed inside the telescopic plate.

[0010] Furthermore, the second fixing mechanism includes an installation groove formed inside the telescopic plate. A ejector rod is disposed inside the installation groove. A third spring is disposed inside the installation groove, and two ends of the third spring respectively abut against the ejector rod and the inner wall of the installation groove.

[0011] Furthermore, a ball is disposed on the top of the plug rod.

[0012] Furthermore, the lower surfaces of the first side block and the second side block are located on the same plane.

[0013] Furthermore, the number of the sliding rods is two, and the two sliding rods are respectively located on two sides in the width direction of the telescopic plate.

[0014] Furthermore, a rubber pad is disposed on the outer surface of the slider, and anti-slip lines are formed on the outer surface of the rubber pad.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows.

[0016] 1. By making the abutting plates on both sides respectively abut against both sides of the inner wall of the ditch, the present utility model can quickly read the measurement value through the corresponding position of the pointer and the scale line, so as to achieve the purpose of quickly measuring the diameter of the ditch. One person can complete the measurement. Moreover, since the abutting plates on both sides abut against the inner wall of the ditch to play a limiting role, the hollow plate and the telescopic plate can be kept at an angle perpendicular to the side wall of the ditch, so that the measurement error can be reduced, the measurement accuracy can be improved, and it is beneficial to the rapid development of the project.

[0028] In the embodiments of the present utility model, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0029] Please refer to Figures 1 - 7 , a water conservancy ditch diameter measuring device provided by the present utility model includes a hollow plate 100, a telescopic plate 101 is inserted inside the hollow plate 100, a through groove 102 is opened on the outer surface of the hollow plate 100 along its length direction, a pointer 103 is installed on the outer surface of the telescopic plate 101, and the pointer 103 is arranged in the through groove 102, and scale lines 104 are arranged on the outer surface of the hollow plate 100 along its length direction. First side blocks 105 and second side blocks 106 are respectively installed on the opposite surfaces of the hollow plate 100 and the telescopic plate 101, a rotating shaft 107 is penetrated and rotatably installed inside both the first side block 105 and the second side block 106, and abutting plates 108 are installed at both ends of the rotating shaft 107. Arc-shaped blocks 109 are installed on the outer surfaces of both the first side block 105 and the second side block 106, two jacks 110 are opened on the inner wall of the arc-shaped block 109, and the included angle between the two jacks 110 is 90 degrees, and a first fixing mechanism 200 that is inserted and matched with the jack 110 is arranged inside one of the abutting plates 108.

[0030] When using this device, first pull out the telescopic plate 101 from the hollow plate 100. Then, through the plug-in fit between the first fixing mechanism 200 and the jack 110, the abutting plate 108 is fixed at a vertical angle. The surveyor holds the hollow plate 100 and makes the two abutting plates 108 on both sides respectively abut against the inner walls on both sides in the width direction of the ditch. At this time, the position where the pointer 103 points on the scale line 104 is the diameter of the ditch. The surveyor can hold this device and measure at intervals along the length direction of the ditch. Moreover, the materials of the hollow plate 100 and the telescopic plate 101 can be hard materials such as plastic and wood, so that when using this device for long-distance measurement, the measuring tape will not bend downwards, improving the measurement accuracy. When the measurement is completed, the telescopic plate 101 is retracted into the hollow plate 100, which can reduce the volume of the whole device and is convenient for carrying and storage.

[0031] Specifically, the first fixing mechanism 200 includes a plug rod 201 arranged inside the abutting plate 108. A slider 202 is slidably installed on the outer surface of the abutting plate 108, and the slider 202 is connected to the plug rod 201. A first spring 203 is arranged inside the abutting plate 108. The two ends of the first spring 203 respectively abut against the inner wall of the abutting plate 108 and the plug rod 201. When it is necessary to adjust the angle of the abutting plate 108, first slide the slider 202 downwards to drive the plug rod 201 to contract inwards and pull it out from the jack 110. At this time, the fixing of the abutting plate 108 is released and it can be rotated. During the rotation of the abutting plate 108, release the slider 202. When the abutting plate 108 rotates to another angle, the plug rod 201 corresponds to the jack 110. At this time, the compressed first spring 203 releases elastic force, so it can push the plug rod 201 to insert into the jack 110 for fixing, thus achieving the purpose of adjusting the angle of the abutting plate 108.

[0032] Specifically, a slide bar 300 is installed inside the hollow plate 100 along its length direction. A slide sleeve 301 is sleeved on the outer surface of the slide bar 300. The end of the slide sleeve 301 is connected to the telescopic plate 101. A second spring 302 is sleeved on the outer surface of the slide bar 300. Two ends of the second spring 302 are respectively abutted against the inner wall of the hollow plate 100 and the slide sleeve 301. A through hole 303 is formed on the surface of the hollow plate 100. A second fixing mechanism 400 which is inserted and matched with the through hole 303 is arranged inside the telescopic plate 101. The elastic force of the second spring 302 acts on the slide sleeve 301, and can apply a thrust to the telescopic plate 101 to push it out of the outside of the hollow plate 100. Therefore, when measuring, the abutting plates 108 on both sides can be tightly abutted against both sides of the inner wall of the ditch through the elastic force of the second spring 302, improving the portability and accuracy of the measurement. The second fixing mechanism 400 includes an installation groove 401 formed inside the telescopic plate 101. A ejector rod 402 is arranged inside the installation groove 401. A third spring 403 is arranged inside the installation groove 401. Two ends of the third spring 403 are respectively abutted against the ejector rod 402 and the inner wall of the installation groove 401. When the telescopic plate 101 is retracted into the hollow plate 10, the ejector rod 402 can be first pressed into the installation groove 401. When the ejector rod 402 moves to a position corresponding to the through hole 303, the compressed third spring 403 releases its elastic force, pushing the ejector rod 402 to jack up and insert into the through hole 303, so that the telescopic plate 101 can be fixed inside the hollow plate 100 to overcome the thrust of the second spring 302.

[0033] Specifically, a ball 500 is arranged on the top of the insertion rod 201. Through the arrangement of the ball 500, the friction between the end of the insertion rod 201 and the arc-shaped block 109 can be reduced, so that the resistance is small and the smoothness is high when the abutting plate 108 rotates.

[0034] Specifically, the lower surfaces of the first side block 105 and the second side block 106 are on the same plane. When measuring the ditch, the abutting plates 108 on both sides are respectively abutted against both sides of the inner wall in the width direction of the ditch, and the first side block 105 and the second side block 106 are respectively placed on the ground. Since the lower surfaces of the first side block 105 and the second side block 106 are on the same plane, it can be ensured that the hollow plate 100 and the telescopic plate 101 are at a horizontal angle, improving the measurement accuracy.

[0035] Specifically, the number of the slide bars 300 is two, and the two slide bars 300 are respectively located on both sides in the width direction of the telescopic plate 101. Through the arrangement of the two slide bars 300, a stable thrust can be provided for the telescopic plate 101, improving the use effect.

[0036] Specifically, a rubber pad is arranged on the outer surface of the slider 202, and anti-slip lines are arranged on the outer surface of the rubber pad. Through the arrangement of the rubber pad and the anti-slip lines, the friction between the slider 202 and the hand can be increased, reducing the situation of hand slipping and improving the use feel.

[0037] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
