Description

Technical Field

[0001] This invention relates to the field of sports measurement technology, and in particular to an intelligent sports long jump measuring device and its measuring method. Background Technology

[0002] When schools organize sports meets, they will hold long jump competitions. The long jump process involves students jumping from the starting position and landing in the sandpit. When measuring the score, the position of the first landing point is measured from the starting position.

[0003] A sports long jump measuring device is disclosed in Chinese Publication Application No. CN220176006U, relating to the field of sports equipment. This device includes a sandpit platform with a sandpit body. A measuring ruler is located on one side of the sandpit platform, and a laser emitter is located on the other side. A guide rail is located at the bottom of the laser emitter. A positioning reference column is located inside the sandpit body, with a laser alignment groove on the column and a bubble level at the top. This device replaces the traditional tape measure method with a measuring ruler, positioning reference column, and laser emitter during measurement. This method is more accurate, using a bubble level to ensure the positioning reference column is vertical, and readings from the measuring ruler using the laser emitter to read the long jump distance. The method is simple, convenient, and can be operated by a single person.

[0004] The aforementioned existing technology requires manual intervention to fix the positioning reference column when measuring distance. The accuracy of manual intervention is poor, which affects the measurement results. In addition, the sand that has been stepped on and sunken after measurement needs to be manually spread out, which affects efficiency.

[0005] Therefore, it is necessary to propose an intelligent sports long jump measurement device and its measurement method to solve the above problems. Summary of the Invention

The side wall of the outer rod has an opening communicating with the movable hole. The side wall of the inner cylinder has a pointer corresponding to the opening, and the pointer extends outward through the opening. A scale plate is installed on the side of the sand tank near the support.

[0010] One end of the second lead screw is threadedly connected to a paving moving seat corresponding to the outer rod.

[0011] Preferably, a guide rod is provided between the two fixed seats, parallel to the first lead screw and the second lead screw, and the paving moving seat and the measuring moving seat are both guided by the guide rod.

[0012] Preferably, the outer rod is uniformly surrounded by a first locking tooth at the end away from the measuring moving seat, and the paving moving seat is uniformly surrounded by a second locking tooth that corresponds to and matches the first locking tooth at the side near the outer rod, and the second locking tooth engages with the first locking tooth.

[0013] Preferably, the guide block and the first guide groove are configured such that when the drive rod moves closer to the torsion spring, the inner cylinder drives the pointer to move in the direction of the sand pool, and when the inner cylinder rotates to the limit angle, the pointer can be horizontal, and at this time the end of the pointer away from the inner cylinder corresponds to the scale plate.

[0014] Preferably, the paving mobile seat is provided with a paving assembly, the paving assembly including a paving frame fixedly installed on the paving mobile seat in the direction close to the inner side of the sand pool, and the bottom of the paving frame is uniformly and vertically provided with first rake teeth.

[0015] Preferably, the top of the paving frame is provided with a groove, and a lifting plate is longitudinally and movably connected to the inner side of the groove. The bottom of the lifting plate is uniformly and vertically provided with second rake teeth spaced apart from the first rake teeth, and the lower end of the second rake teeth extends to the bottom of the paving frame. The paving moving seat is provided with a connecting groove on the side near the paving frame. One end of the lifting plate extends to the inner side of the connecting groove. The side wall of the paving moving seat is provided with a through hole communicating with the connecting groove. A driving block is movably connected to the through hole. A second guide groove is provided in the middle of the top of the driving block, and the two ends of the inner side of the second guide groove are sloped. The second guide groove corresponds to the end of the lifting plate located inside the connecting groove.

[0016] Preferably, the second guide groove and the lifting plate are configured such that when the end of the lifting plate corresponds to the top end of the drive block, the bottom of the second rake tooth is higher than the bottom of the first rake tooth, and when the end of the large lifting plate corresponds to the bottom of the inner side of the second guide groove, the bottom of the second rake tooth is flush with the bottom of the first rake tooth.

[0017] Preferably, a spring for resetting the lifting plate is vertically arranged between the bottom of the second rake tooth and the bottom of the inner cavity of the groove.

[0018] Preferably, a take-off platform is provided at one end of the sandpit, a running track is provided at the end of the take-off platform away from the sandpit, and a pressure sensor is provided at the bottom of the take-off platform.

[0019] A measurement method for an intelligent sports long jump measuring device includes the following steps:

[0020] S1: When the athlete jumps, he steps on the take-off board to jump into the sand pit. After the pressure sensor detects the pressure, the camera identifies the landing point closest to the take-off board. Then, the second motor drives the first lead screw to rotate, and the first motor drives the second lead screw to rotate.

[0021] S2: Then measure the displacement of the moving seat and the paving moving seat when they are close together. When the pointer corresponds to the landing point, the first screw stops first and waits for the paving moving seat to contact the outer rod. Then the second screw stops. At this time, the first locking tooth and the second locking tooth engage and lock. Then the first screw continues to rotate. At this time, the outer rod remains stationary and the drive rod moves closer to the torsion spring. With the cooperation of the guide block and the first guide groove, the inner cylinder rotates and the torsion spring twists. Then the inner cylinder drives the pointer to rotate. One end of the pointer corresponds to the scale plate, and the distance is measured.

[0022] S3: When the water flows towards the measuring moving seat, it will drive the paving frame and the first rake tooth to move as a whole. Initially, one end of the lifting plate is located at the top of the drive block near the first motor. Therefore, the bottom of the second rake tooth is higher than the bottom of the first rake tooth. When the paving moving seat drives the paving frame to move closer to the outer rod, the first rake tooth combs the sand in the sand pit. When the paving moving seat contacts the outer rod, the drive plate will push the drive block to move. The drive block is guided by the slope at one end of the second guide groove, and the spring reset lifting plate moves down. At this time, the bottom of the second rake tooth corresponds to the bottom of the first rake tooth.

[0023] S4: After the measurement is completed, the first and second lead screws are reversed, causing the paving moving seat and the measuring moving seat to move away from each other. Then the pointer is reset and flipped upward. The paving frame drives the first and second rake teeth to spread sand. When the paving moving seat moves to the initial position, one end of the drive block will touch the fixed seat near the first motor. Then the lifting plate is driven to rise again, and the second rake tooth is driven to rise again, preparing for the next sand combing.

[0024] Compared with the prior art, the present invention provides an intelligent sports long jump measuring device and its measuring method, which has the following beneficial effects:

[0025] This intelligent sports long jump measuring device and its measuring method can automatically measure the long jump distance through an automatic measuring mechanism. It has a high degree of automation, high measurement accuracy, and is convenient and fast, improving efficiency. When used with a paving component, it can automatically spread sand, facilitating subsequent use. The linkage setting and compact structure increase its practicality. Attached Figure Description

The guide block 28 and the first guide groove 27 are configured such that when the drive rod 19 moves closer to the torsion spring 24, the inner cylinder 22 drives the pointer 8 to move inward toward the inside of the sand pool 1. When the inner cylinder 22 rotates to the limit angle, the pointer 8 can be horizontal. At this time, the end of the pointer 8 away from the inner cylinder 22 corresponds to the scale plate 5.

[0038] To increase the stability of the measuring moving seat 17 and the paving moving seat 16 during displacement, a guide rod 15 is provided between the two fixed seats 9, which is parallel to the first lead screw 10 and the second lead screw 11. Both the paving moving seat 16 and the measuring moving seat 17 are movably guided by the guide rod 15.

[0040] In addition, a paving assembly is provided on the paving moving base 16. The paving assembly includes a paving frame 12 fixedly installed on the paving moving base 16 near the inner side of the sand pit 1. First rake teeth 18 are evenly and vertically arranged at the bottom of the paving frame 12. A groove 30 is provided at the top of the paving frame 12.

When the end of the large lifting plate 31 corresponds to the bottom of the inner side of the second guide groove 35, the bottom of the second rake tooth 32 is flush with the bottom of the first rake tooth 18. A spring 38 for resetting the lifting plate 31 is vertically provided between the bottom of the second rake tooth 32 and the bottom of the inner cavity of the groove 30.

[0041] A measurement method for an intelligent sports long jump measuring device includes the following steps:

[0042] Step 1: When the athlete jumps, he steps on the take-off board 3 to take off into the sand pit 1. After the pressure sensor detects the pressure, the camera 7 identifies the landing point closest to the take-off board 3. Then, the second motor 14 drives the first lead screw 10 to rotate, and the first motor 13 drives the second lead screw 11 to rotate.

[0043] Step 2: Then measure the displacement of the moving seat 17 and the paving moving seat 16 as they approach each other. When the pointer 8 corresponds to the landing point, the first lead screw 10 stops first, waiting for the paving moving seat 16 to contact the outer rod 20. Then the second lead screw 11 stops. At this time, the first locking tooth 29 and the second locking tooth 33 engage and lock. Then the first lead screw 10 continues to rotate. At this time, the outer rod 20 remains stationary. The drive rod 19 moves closer to the torsion spring 24. With the cooperation of the guide block 28 and the first guide groove 27, the inner cylinder 22 rotates. The torsion spring 24 twists, and then the inner cylinder 22 drives the pointer 8 to rotate. One end of the pointer 8 corresponds to the scale plate 5, and the distance is measured.

[0044] Step 3: When the water flows to the measuring moving seat 17, it will drive the paving frame 12 and the first rake tooth 18 to move as a whole. Initially, one end of the lifting plate 31 is located at the top of the drive block 34 near the end of the first motor 13. Therefore, the bottom of the second rake tooth 32 is higher than the bottom of the first rake tooth 18. When the paving moving seat 16 drives the paving frame 12 to move closer to the outer rod 20, the first rake tooth 18 combs the sand in the sand pit 1. When the paving moving seat 16 contacts the outer rod 20, the drive plate 21 will push the drive block 34 to move. The drive block 34 is guided by the slope of one end of the second guide groove 35. The spring 38 resets the lifting plate 31 and moves it down. At this time, the bottom of the second rake tooth 32 corresponds to the bottom of the first rake tooth 18.

[0045] Step 4: After the measurement is completed, the first lead screw 10 and the second lead screw 11 are driven to reverse, thereby displacing the paving moving seat 16 and the measuring moving seat 17 away from each other. Then the pointer 8 is reset and flipped upward. The paving frame 12 drives the first rake tooth 18 and the second rake tooth 32 to spread sand. When the paving moving seat 16 moves to the initial position, one end of the drive block 34 will touch the fixed seat 9 near the first motor 13. Then the lifting plate 31 is driven to rise again, and the second rake tooth 32 is driven to rise again, preparing for the next sand combing.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
