Description

Technical Field

[0001] The utility model relates to the technical field of road detection, and particularly relates to a detector. Background Technique

[0002] A detection instrument is a device or instrument used to test, measure, and analyze an object. During the acceptance process after road construction, different detectors are needed to detect various data of the road to verify the road quality. Among them, a permeameter is an instrument used to measure the water permeability of a road surface. It is mainly used to determine the water permeability coefficient of an asphalt mixture road surface and a compacted asphalt mixture specimen, as well as to measure the water seepage volume per unit time of an asphalt road surface under a certain variable water head. The permeameter consists of multiple parts. Among them, the graduated cylinder is the main tool for staff to observe the water permeability of the road surface, and it is usually made of plexiglass.

[0003] Currently, when some permeameters are in use, the staff will inject an appropriate amount of water into the graduated cylinder. Then, the water source enters the road surface through the permeameter. The staff can regularly observe the water source in the graduated cylinder to judge the water permeability of the road surface. During this process, the staff mainly judges the decrease in the water level by observing the scale line on the surface of the graduated cylinder. Since the permeameter needs to be placed on the road surface during use, and the detection work is mostly carried out on sunny days, and the graduated cylinder is mostly made of transparent glass, it is inconvenient for the staff to observe the values on the surface of the graduated cylinder under strong light. Moreover, when the staff observes the data, they need to squat down and keep their line of sight parallel to the water surface to obtain accurate values, which is rather inconvenient.

[0004] The purpose of the utility model is to provide a detector to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A detector, including a permeameter body and a graduated cylinder body installed on the top of the permeameter body, further including:

DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figures 1-5 As shown, a detector includes a water seepage meter body 1 and a measuring cylinder body 2 installed on the top of the water seepage meter body 1, a fixing rod 3 is fixedly connected to the top of the water seepage meter body 1, the number of the fixing rods 3 is two, an adjusting mechanism 4 is installed at one end of the fixing rod 3, an index rod 5 is installed on the surface of the adjusting mechanism 4, a hollow frame 6 is fixedly connected to the top of the water seepage meter body 1, a slide plate 7 is slidably connected to the upper part of the inner wall of the hollow frame 6, a reset mechanism 8 is installed at the bottom of the slide plate 7, a measuring plate 9 is fixedly connected to the top of the slide plate 7, a groove 10 is provided on the surface of the measuring plate 9, the height of the measuring plate 9 is equal to the height of the measuring cylinder body 2, and the width of the inner wall of the groove 10 is greater than the width of the index rod 5, thereby reducing the obstruction of the groove 10 to the movement of the index rod 5.

[0023] The reset mechanism 8 includes a guide rod 81, a reset plate 82 and a compression spring 83. The two ends of the guide rod 81 are fixedly connected to the two sides of the inner wall of the hollow frame 6 respectively, and the reset plate 82 is fixedly connected to the bottom of the slide plate 7. The guide rod 81 slides through the reset plate 82. The compression spring 83 is sleeved on the surface of the guide rod 81. The two ends of the compression spring 83 are fixedly connected to the surface of the reset plate 82 and the inner wall of the hollow frame 6 respectively. When the staff presses the measuring plate 9, the slide plate 7 drives the reset plate 82 to move. At this time, the measuring plate 9 can be better used with the index rod 5. Thereafter, under the action of the elastic force of the compression spring 83, the slide plate 7 drives the measuring plate 9 to reset, thereby reducing the contact between the index rod 5 and the measuring plate 9.

[0024] The adjusting mechanism 4 includes a turntable 41, a connecting rope 42, a floating plate 43 and an adjusting plate 44. The surface of the turntable 41 is rotatably connected to one end of the fixed rod 3. A groove is formed on the surface of the turntable 41. The surface of the connecting rope 42 is in contact with the inner wall of the groove. The floating plate 43 is fixedly connected to one end of the turntable 41. The adjusting plate 44 is fixedly connected to the other end of the connecting rope 42. The adjusting plate 44 is slidably sleeved on the surface of the fixed rod 3. When the staff pulls the adjusting plate 44, the connecting rope 42 drives the floating plate 43 to rise under force. During this process, the turntable 41 can guide the connecting rope 42. After that, the staff can introduce water into the inside of the measuring cylinder body 2. The floating plate 43 contacts the water surface and can float on the water surface. At this time, the adjusting plate 44 can stabilize its height under the action of gravity. The connecting rope 42 is stretched under force. The index rod 5 is fixedly connected to the surface of the adjusting plate 44. At this time, the index rod 5 can cooperate with the measuring plate 9.

[0025] An extension plate 11 is fixedly sleeved on the surface of the fixed rod 3. The top of the measuring plate 9 is slidably matched with the bottom of the extension plate 11. The extension plate 11 can guide the movement of the measuring plate 9. A through groove 12 is formed at the top of the extension plate 11. The extension plate 11 can limit the movable range of the adjusting plate 44. The other end of the connecting rope 42 can pass through the through groove 12 and be fixedly connected to the top of the adjusting plate 44. The inner diameter of the through groove 12 is larger than the diameter of the connecting rope 42.

[0026] A notch is formed on the surface of one side of the hollow frame 6. The height of the bottom of the inner wall of the notch is equal to the height of the bottom of the sliding plate 7. Through the setting of the notch, it is convenient for the staff to press the sliding plate 7.

[0027] Working principle: The staff first installs the water permeability tester body 1 on the road surface to be detected. After that, the staff can pull the adjusting plate 44 downward. The connecting rope 42 drives the floating plate 43 to rise under force. Accordingly, the floating plate 43 can be moved out from the top of the measuring cylinder body 2. At the same time, the staff can pour an appropriate amount of water into the inside of the measuring cylinder body 2, that is, the height of the water surface inside the measuring cylinder body 2 needs to be flush with the highest scale line on the surface of the measuring cylinder body 2. After that, the staff can put the floating plate 43 into the inside of the measuring cylinder body 2. At this time, under the action of buoyancy, the floating plate 43 can be stably placed on the water surface. The adjusting plate 44 stabilizes its height under the action of gravity. Then the staff can press the sliding plate 7, and the measuring plate 9 moves accordingly. At this time, the staff can record the height of the adjusting plate 44 through the cooperation of the index rod 5 and the measuring plate 9. The detector is left standing for a certain period of time. The staff can first pull down the adjusting plate 44. Then under the action of gravity, the floating plate 43 descends and contacts the water surface. Accordingly, the possibility of the surface of the floating plate 43 fitting with the inner wall of the measuring cylinder body 2 can be reduced. Then the staff presses the sliding plate 7 again, and the measuring plate 9 moves and cooperates with the index rod 5. The staff can record the value after water seepage. After that, the staff compares the data measured twice to calculate the water permeability performance of the road.
