DETAILED DESCRIPTION

[0028] 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.

[0029] The following first describes the concepts involved in the present application in conjunction with the accompanying drawings. It should be noted that the following description of each concept is only to make the content of the present application easier to understand, and does not limit the scope of protection of the present application; at the same time, the embodiments and features in the embodiments of the present application can be combined with each other in the absence of conflict. The present application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments.

[0030] like Figure 1 - Figure 8As shown, the utility model provides a measuring instrument positioning and installation mechanism for a wave water tank 1, comprising a water tank 1, a towing vehicle 2 is slidably connected to the top of the water tank 1 through a track, a flange 3 for installing a measuring instrument, an X-direction position adjustment system 4 for driving the flange 3 to adjust its position along the X-coordinate direction, and a Y-direction position adjustment system 5 for driving the flange 3 to adjust its position along the Y-coordinate direction are arranged at the bottom of the towing vehicle 2, the X-direction position adjustment system 4 is arranged at the bottom of the towing vehicle 2, the Y-direction position adjustment system 5 is fixedly arranged at the bottom of the X-direction position adjustment system, the flange 3 is fixedly installed at the bottom of the Y-direction position adjustment system 5 by bolts, mobile devices that move along the width direction of the water tank 1 and the vertical direction of the water tank 1 are installed inside the X-direction position adjustment system 4 and the Y-direction position adjustment system 5, and a distance measuring sensor 6 for measuring the walking distance of the towing vehicle 2 in the Z-coordinate direction is also arranged on the side wall of the towing vehicle 2.

[0031] Before use, the utility model is installed on the flange 3, and then the three coordinates of X, Y, and Z are input into the upper computer. The flange 3 at the lower end of the towing vehicle 2 can be automatically moved to the corresponding coordinate point through the cooperation of the X-direction position adjustment system 4 and the Y-direction position adjustment system 5, wherein the X-direction refers to the width direction of the water tank 1, the Y-direction is the vertical direction, the X-direction and the Y-direction are positioned by the XY mobile device installed on the towing vehicle 2, and the Z-direction refers to the direction of horizontal movement along the length of the water tank 1. The walking function of the towing vehicle 2 is used in conjunction with the long-distance distance measuring sensor 6 to position the towing vehicle 2. When the towing vehicle 2 moves, the long-distance distance measuring sensor 6 is used to measure the length in the Z-direction, that is, the length of the towing vehicle 2 moving horizontally on the water tank 3.

[0032] The utility model can realize convenient and fast installation of the measuring instrument, greatly reducing damage to the water tank 1, and the mutual cooperation of the X-direction position adjustment system 4 and the Y-direction position adjustment system 5 can quickly move the measuring instrument on the flange 3 in the horizontal and vertical directions along the water tank 1, so as to adjust the position of the measuring instrument for use, wherein the X-direction position adjustment system 4 and the Y-direction position adjustment system 5 are combined into a T-shape, and the angle between the two is 90 degrees, which can reduce the measurement error of the measuring instrument in the horizontal and vertical directions, improve the measurement accuracy and measurement efficiency, and the T-shaped setting enhances the stability of the Y-direction position adjustment system 5 when moving horizontally, thereby improving the safety of the measuring instrument.

[0033] It is worth noting that the instrument mounting flange 3 has a load capacity of 5 kg; the closest distance that the flange 3 can approach the side wall of the water tank 1 is no more than 0.1 m, thereby reducing the measurement error.

[0034] Furthermore, the Y-direction position adjustment system 5 includes a moving seat 51, a fixed column 52, a connecting column 53 and an electric push rod 54. The moving seat 51 is located below the X-direction position adjustment system 4 and is transmission-connected to the X-direction position adjustment system 4. The fixed column 52 is fixedly connected to the bottom of the moving seat 51. A groove 55 is provided inside the fixed column 52. The electric push rod 54 is installed in the groove 55. The connecting column 53 is located directly below the fixed column 52, and the output shaft of the electric push rod 54 is fixedly connected to the top of the connecting column 53.

[0035] When adjusting the measuring instrument on the flange 3, the flange 3 can be driven down by pushing the connecting column 53 down through the electric push rod 54 to adjust the height of the measuring instrument; further, the Y-direction position adjustment system 5 also includes two guide rods 56 and two measuring components 57 for measuring the height of the water tank 1, and first mounting grooves 58 are opened on both sides of the inner wall of the movable seat 51, and second mounting grooves 59 are opened on both sides of the inner wall of the connecting column 53. The two first mounting grooves 58 correspond to the two second mounting grooves 59. One end of the two guide rods 56 is respectively fixed in the two second mounting grooves 59, and the other end of the two guide rods 56 extends to the first mounting groove 58 corresponding thereto, and is slidably connected to the first mounting groove 58, and the two measuring components 57 are respectively installed on the top of the two first mounting grooves 58.

[0036] By setting the two guide rods 56, it is possible to guide the connecting column 53 when the electric push rod 54 drives it to descend, so as to prevent the connecting column 53 from falling when the electric push rod 54 is loose. Furthermore, in order to facilitate the measurement of the lifting height of the flange 3, a measuring component 57 is set in the two first mounting grooves 58. The measuring component 57 includes a winding roller 60, a measuring tape 61 and an encoder 62. The winding roller 60 is rotatably set at the top of the first mounting groove 58, and the encoder 62 is installed in the first mounting groove 58, and the encoder 62 is fixedly connected to the winding roller 60. A through hole 63 is opened in the two guide rods 56, and one end of the measuring tape 61 is fixedly connected to the winding roller 60 through a ruler spring, and the other end of the measuring tape 61 passes through the through hole 63 and is fixedly connected to the top of the flange 3 by bolts.

[0037] By fixing one end of the measuring tape 61 to the top of the flange 3, when the electric push rod 54 drives the connecting column 53 to descend, one end of the measuring tape 61 can be pulled to stretch. When one end of the measuring tape 61 is pulled, the winding roller 60 at the other end for winding up the measuring tape 61 can be driven to rotate. When the winding roller 60 rotates, the encoder 62 starts to count the number of revolutions of the winding roller, so as to obtain the length of the stretched measuring tape 61 according to the total length of each revolution. Since the measuring tape 61 is connected to the winding roller 60 through a ruler spring, when the electric push rod 54 is pulled, the measuring tape 61 is pulled. When the movable connecting column 53 is reset, the measuring tape 61 is also reeled and reset at the same time. The working principle here is the same as that of the tape measure in the prior art. Therefore, it is not described in detail. The present invention can prevent the measuring tape 61 from being exposed in the water tank 1 when stretched by arranging the measuring component 57 in the first mounting groove 58, thereby avoiding contamination by water or other dust impurities and avoiding affecting the measurement accuracy. In addition, the arrangement of the measuring component 57 can facilitate the monitoring of the height of the flange 3, and further obtain the height of the water tank 1 or the height from the water surface to the top of the water tank 1.

[0038] A guide roller 64 is rotatably disposed in the first mounting groove 58, and the guide roller 64 is located below the winding roller 60, and the measuring tape 61 is in conflict with the surface of the guide roller 64. The setting of the guide roller 64 can guide the measuring tape 61, thereby preventing the measuring tape 61 from rubbing against the guide rod 56 or the inner wall of the first mounting groove 58, thereby increasing the service life of the measuring tape 61.

[0039] The outer wall of the top of the guide rod 56 is fixedly connected with a rubber sleeve 65, and the outer wall of the rubber sleeve 65 is axially sealed with the inner wall of the first mounting groove 58. The setting of the rubber sleeve 65 can prevent the external air or water from entering the first mounting groove 58 and contaminating the measuring tape 61, thereby affecting the accuracy of the measurement data.

[0040] The bottom of the measuring tape 61 is fixedly connected with a connecting plate 66, which is fixedly connected to the top of the flange 3 by bolts, and the connecting plate 66 is adapted to the second mounting groove 59. The setting of the connecting plate 66 can facilitate the installation and removal between the measuring tape 61 and the flange 3, and when the flange 3 and the connecting plate 66 are released from the fixed connection, the diameter of the connecting plate 66 is adapted to the second mounting groove 59 or larger than the through hole 63, so that the measuring tape 61 can be prevented from being rolled up to the winding roller 60.

[0041] This article uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only used to help understand the method and its core ideas of this application. The above is only the preferred implementation method of this application. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of this application, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the invention to other occasions without improvement, should be regarded as the scope of protection of this application.
