[0029] Example: Figure 1-7As shown, this utility model provides an ultrasonic flow field velocity measurement experimental device, including a base plate 1, a side plate 11, a transducer 2, a signal processor 3, and a measuring pipe 4. The side plate 11 and the signal processor 3 are fixedly mounted on the upper surface of the base plate 1. The transducer 2 is detachably mounted on one side of the side plate 11, and the measuring pipe 4 is detachably mounted on the upper surface of the base plate 1. During fluid velocity measurement, the fluid flows through the measuring pipe 4, and the transducer 2 emits ultrasonic signals toward the measuring pipe 4. The flow velocity and flow rate are derived from the time difference or frequency difference of the ultrasonic signals propagating in the fluid. Simultaneously, the transducer 2 receives the ultrasonic signals. The signal processor 3 analyzes and processes the received ultrasonic signal, converts the signal received by the transducer 2 into readable flow data, and derives the fluid velocity and flow rate. This is existing technology and will not be elaborated here. A moving detection component 5 is provided on the side plate 11, and an assembly component 6 is provided on the moving detection component 5. By setting the moving detection component 5 and the assembly component 6, the assembly component 6 can easily realize the assembly of the transducer 2 and facilitate replacement. The moving detection component 5 can make the transducer 2 move along the direction of the measuring pipe 4, and can detect the fluid velocity and flow rate at different positions in the measuring pipe 4.

[0030] The motion detection assembly 5 includes a movable disk 51, a sliding groove 53 on the side plate 11, the movable disk 51 is slidably disposed in the sliding groove 53, and a plurality of balls 52 arranged in a ring array are rotatably mounted on the outer wall of the movable disk 51. The outer wall of the balls 52 is in active contact with the inner wall of the sliding groove 53. By setting the movable disk 51, the balls 52 and the sliding groove 53, the movable disk 51 can slide in the sliding groove 53. The balls 52 can improve the stability of the movable disk 51 when it moves. A fixing rod 54 is fixedly disposed on one side of the movable disk 51, and a fixing plate 55 is fixedly disposed on one end of the fixing rod 54. The transducer 2 is detachably mounted on one side of the fixing plate 55. A push-pull rod 56 is fixedly disposed on the other side of the movable disk 51, and a handle 57 is fixedly disposed on one end of the push-pull rod 56. By holding the handle 57, the handle 57 can move the transducer 2 along the direction of the sliding groove 53 through the push-pull rod 56, the movable disk 51 and the fixing rod 54.

[0031] A number of elastic sleeves 12 are fixedly installed on the upper surface of the base plate 1. The inner wall of the elastic sleeve 12 is in contact with the outer wall of the measuring pipe 4. By setting the elastic sleeves 12, the elastic sleeves 12 can fix the measuring pipe 4 on the upper surface of the base plate 1 through their own elasticity. At the same time, the measuring pipe 4 can be disassembled and replaced.

[0032] Assembly component 6 includes two curved clamping plates 61. The transducer 2 is detachably mounted between the two curved clamping plates 61. A rubber pad 611 is fixedly mounted on one side of each curved clamping plate 61, and one side of the rubber pad 611 is in movable contact with the outer wall of the transducer 2. By using two curved clamping plates 61 and two rubber pads 611, the transducer 2 can be clamped tightly by the rubber pads 611 when the two curved clamping plates 61 are close together. Conversely, the transducer 2 can be disassembled and replaced when the two curved clamping plates 61 are far apart. Two movable seats 62 are slidably mounted on one side of the fixing plate 55. An L-shaped connecting frame 63 is fixedly mounted on one side of each movable seat 62. One end of the L-shaped connecting frame 63 is fixedly connected to the outer wall of the curved clamping plate 61. By driving the movable seats 62 to move horizontally, the movable seats 62 can be connected to the outer wall of the curved clamping plate 61 via the L-shaped connecting frame 63. The faceplate 61 moves horizontally synchronously. A guide rail 64 is fixedly installed on one side of the fixed plate 55. Guide blocks 65 are slidably installed at both ends of the guide rail 64. The movable seat 62 is fixedly connected to one side of the guide block 65. By setting the guide rail 64 and the guide block 65, the guide block 65 can slide horizontally along the guide rail 64, thereby allowing the movable seat 62 to move horizontally. A double-ended screw 66 is rotatably installed on one side of the fixed plate 55. The double-ended screw 66 is threadedly rotatably connected to the two movable seats 62. Two support plates 67 are fixedly installed on one side of the fixed plate 55. The double-ended screw 66 is rotatably connected to the support plates 67. A knob 68 is fixedly installed at one end of the double-ended screw 66. By manually rotating the knob 68, the double-ended screw 66 can be rotated, and the double-ended screw 66 can drive the two movable seats 62 to move closer or further apart.

[0033] Working principle: When it is necessary to detect the flow rate and flow volume of a fluid, the operator first injects the fluid into the measuring pipe 4. The fluid flows in the measuring pipe 4 (the fluid is collected by a collection tank at the end of the measuring pipe 4). Then, the transducer 2 and the signal processor 3 are started at the same time. The operator holds the handle 57, which moves the transducer 2 along the sliding groove 53 via the push-pull rod 56, the moving plate 51, and the fixed rod 54. During this process, the transducer 2 emits ultrasonic signals toward the measuring pipe 4. The flow rate and flow volume are derived from the time difference or frequency difference of the ultrasonic signal propagation in the fluid. At the same time, the transducer 2 receives the ultrasonic signals. The signal processor 3 analyzes and processes the received ultrasonic signals, converting the signals received by the transducer 2 into readable flow data, and deriving the flow rate and flow volume of the fluid.

[0034] As the transducer 2 moves horizontally along the sliding groove 53, the flow velocity and flow rate of the fluid at different locations in the measuring pipe 4 can be detected, thereby improving the convenience of fluid velocity and flow rate detection operations and the comprehensiveness of the detection results.

[0035] When the transducer 2 needs to be replaced, the operator manually turns the knob 68, which causes the double-headed screw 66 to rotate. The double-headed screw 66 drives the two moving seats 62 to move away from each other. The two moving seats 62, through the two L-shaped connecting brackets 63, move the two arc-shaped clamps 61 away from each other. At this time, the transducer 2 is released from clamping and can be taken out from between the two arc-shaped clamps 61. Then, the replaced transducer 2 is placed between the two arc-shaped clamps 61, and the two arc-shaped clamps 61 are driven to move closer to each other. The two arc-shaped clamps 61 clamp the transducer 2 through the two rubber pads 611, so that the transducer 2 is fixed on the front side of the fixing plate 55. This facilitates the replacement of the transducer 2 and effectively improves the convenience of the transducer 2 replacement operation.

The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
