Description

Technical Field

[0001] This utility model relates to the field of ultrasonic measurement technology, specifically to a robot for measuring swimming pool distances based on ultrasonic waves. Background Technology

[0002] As people's living standards improve, their requirements for swimming pool design and construction are becoming increasingly refined and personalized. During use, factors such as foundation settlement and structural aging may cause changes in the pool's dimensions, affecting its normal use and safety.

[0003] Traditional methods for measuring swimming pool dimensions primarily rely on manual measurement using tools such as measuring tapes and laser rangefinders. However, manual measurement has many limitations. For example, the accuracy of measurement is greatly affected by the operator's skills and experience. For large or complex-shaped pools, manual measurement is not only inefficient but also prone to measurement errors. Utility Model Content

[0004] The purpose of this invention is to provide a robot for measuring swimming pool distances based on ultrasonic waves, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a robot for measuring swimming pool distances based on ultrasound, comprising a floating board and a mounting box. A floating bladder is fixedly installed at the bottom of the floating board, and an annular groove is formed at the top of the floating board. A rotating ring is rotatably installed inside the annular groove, and a connecting ring is fixedly installed at the top of the rotating ring. A rotating seat is fixedly installed at the top of the connecting ring, and a threaded hole is formed inside the rotating seat. A circular through hole is formed inside the floating board, and symmetrically arranged limiting sliding holes are formed inside the floating board. A threaded rod is rotatably installed at the top of the mounting box, and a U-shaped bent rod is rotatably installed at the top of the threaded rod. Limiting sliding rods are fixedly installed at both ends of the U-shaped bent rod. Ultrasonic transmitters and receivers are fixedly installed on both sides and the front of the mounting box.

[0006] Preferably, the threaded rod is movably mounted inside the circular through hole, and the threaded rod is threadedly mounted inside the threaded hole.

[0007] Preferably, the two limiting slide rods are slidably installed inside the two limiting slide holes, and the end of the limiting slide rod away from the U-shaped bend is fixedly connected to the top of the mounting box.

[0008] Preferably, a control box is fixedly installed on the top of the floating board, a display screen is fixedly installed on the top of the control box, control buttons are installed on the top of the control box, and a switch button is installed on the top of the control box.

[0009] Preferably, a battery is fixedly installed on the top of the floating plate, and a positioning head placement box is fixedly installed on the top of the battery.

[0010] Preferably, the bottom of the floating board is fixedly equipped with support legs, there are four support legs, and the four mounting boxes are installed in a rectangular symmetrical manner at the four corners of the bottom of the floating board.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by activating the ultrasonic transmitter and receiver, ultrasonic waves are emitted. When several positioning heads receive ultrasonic waves of this frequency, they immediately feed back ultrasonic waves of their own frequency. After receiving ultrasonic waves of these frequencies, the ultrasonic transmitter and receiver can calculate the distances from the floating board to the positioning heads by the time it takes for the sound waves to travel in the water. Since it is a transmission followed by reception, the distance calculation is: distance from the robot to the positioning head = reception time - transmission time * speed of sound in water / 2. This positioning method is not affected by factors such as the shape of the pool and the water quality, and can work stably in various complex pool environments.

[0012] Additionally, the rotating seat can be rotated, and under the limitation of the limiting sliding hole and the limiting sliding rod, the threaded rod can move up and down inside the rotating seat, thereby adjusting the relative position of the mounting box and the ultrasonic transmitter and receiver, making the signal transmission between them and the positioning head more stable and accurate, thus improving the overall performance of the device and ensuring that the pool robot can achieve precise positioning under various working conditions.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a robot for measuring swimming pool distance based on ultrasound, comprising a floating plate 1 and a mounting box 2. A floating bladder 11 is fixedly installed at the bottom of the floating plate 1. An annular groove 20 is formed at the top of the floating plate 1. A rotating ring 17 is rotatably installed inside the annular groove 20. A connecting ring 16 is fixedly installed at the top of the rotating ring 17. A rotating seat 4 is fixedly installed at the top of the connecting ring 16. A threaded hole 18 is formed inside the rotating seat 4. A circular through hole 21 is formed inside the floating plate 1. Limiting sliding holes 19 are symmetrically formed inside the floating plate 1. A threaded rod 15 is rotatably installed at the top of the mounting box 2. A U-shaped bent rod 14 is rotatably installed at the top of the threaded rod 15. Both ends of the U-shaped bent rod 14 are fixed. A limiting slide bar 13 is fixedly installed. An ultrasonic transmitter and receiver 3 is fixedly installed on both sides and the front of the mounting box 2. A threaded rod 15 is movably installed inside the circular through hole 21. The threaded rod 15 is threaded inside the threaded hole 18. Two limiting slide bars 13 are slidably installed inside two limiting slide holes 19 respectively. The end of the limiting slide bar 13 away from the U-shaped bend 14 is fixedly connected to the top of the mounting box 2. A control box 6 is fixedly installed on the top of the floating plate 1. A display screen 8 is fixedly installed on the top of the control box 6. A control button 7 and a switch button 9 are installed on the top of the control box 6. A storage battery 5 is fixedly installed on the top of the floating plate 1. A positioning head placement box 10 is fixedly installed on the top of the storage battery 5.

[0020] The working principle of the above technical solution is as follows: First, remove the multiple positioning heads from inside the positioning head placement box 10. Then, place the multiple positioning heads on several walls of the pool, ensuring they are not in a straight line. Next, place the float plate 1 on the surface of the pool. The float bladder 11 allows the float plate 1 to float on the water, positioning the installation box 2 inside the pool. Then, activate the three ultrasonic transmitters / receivers 3 inside the installation box 2 using the switch button 9 and control button 7 on the top of the control box 6. These transmitters / receivers emit ultrasonic waves. When each positioning head receives an ultrasonic wave of that frequency, it immediately feeds back an ultrasonic wave of its own frequency. The ultrasonic transmitters / receivers 3, upon receiving these ultrasonic waves, transmit the sound waves through the water. The broadcast time allows for the calculation of the individual distances from the floating plate 1 to the positioning heads. Since the transmission is followed by reception, the distance calculation is: distance from the robot to the positioning head = reception time - transmission time * speed of sound in water / 2. This positioning method is unaffected by factors such as pool shape and water quality, and can work stably in various complex pool environments. In addition, the rotating seat 4 can be rotated, and under the limitation of the limiting sliding hole 19 and the limiting sliding rod 13, the threaded rod 15 can move up and down inside the rotating seat 4, thereby adjusting the relative position of the mounting box 2 and the ultrasonic transmitter and receiver 3, making the signal transmission between them and the positioning head more stable and accurate, thereby improving the overall performance of the device and ensuring that the pool robot can achieve precise positioning under various working conditions.

[0021] In another implementation scheme, such as Figures 1-4 As shown, four support legs 12 are fixedly installed at the bottom of the floating board 1, and four mounting boxes 2 are installed in a rectangular symmetrical manner at the four corners of the bottom of the floating board 1.

[0022] The device can be supported by the support legs 12, ensuring that the mounting box 2 is away from the ground when not in use.

[0023] Working Principle: In use, first remove the multiple positioning heads from inside the positioning head placement box 10, then place them on several walls of the pool, ensuring they are not in a straight line. Next, place the float plate 1 on the pool surface. The float bladder 11 allows the float plate 1 to float on the water, positioning the installation box 2 within the pool water. Then, activate the three ultrasonic transmitters / receivers 3 inside the installation box 2 using the switch button 9 and control button 7 on the top of the control box 6. These transmitters / receivers emit ultrasonic waves. Upon receiving an ultrasonic wave of that frequency, each positioning head immediately feeds back an ultrasonic wave of its own frequency. The ultrasonic transmitters / receivers 3, after receiving these ultrasonic waves, calculate the distance from the float plate 1 to each positioning head based on the time it takes for the sound waves to travel through the water. The distance is calculated as follows: distance from robot to positioning head = receiving time - transmission time * speed of sound in water / 2. This positioning method is not affected by factors such as pool shape and water quality, and can work stably in various complex pool environments. In addition, the rotating seat 4 can be rotated, and under the limit of the limiting sliding hole 19 and the limiting sliding rod 13, the threaded rod 15 can move up and down inside the rotating seat 4, thereby adjusting the relative position of the mounting box 2 and the ultrasonic transmitter and receiver 3, making the signal transmission between them and the positioning head more stable and accurate, thereby improving the overall performance of the device and ensuring that the pool robot can achieve precise positioning under various working conditions. The supporting legs 12 can support the device, ensuring that the mounting box 2 is away from the ground when not in use.
