[0026] Cabinet body 1: Linear motors 4 are respectively fixedly connected to the left and right side walls thereof. Chutes are opened at the rear ends of the moving element seats of the linear motors 4. The left side of the cabinet body 1 is hinged to a cabinet door 2 through a hinge. A single-chip microcomputer 3 is arranged in the middle of the cabinet door 2. An avoidance opening 5 is opened at the rear end of the bottom of the cabinet body 1. Fixed feet are symmetrically arranged on the left and right sides of the cabinet body 1. The water flow velocity measurement staff needs to first fix the cabinet body 1 at a suitable position through the fixed feet, and then turn on the single-chip microcomputer 3 to start the linear motor 4 through the single-chip microcomputer 3, so that the moving element seat of the linear motor 4 drives the measuring mechanism 8 to move backward to the upper end of the avoidance opening 5;

[0027] Measuring mechanism 8: It includes a fixed frame 81, an electric push rod 83, a connecting rod 84 and a detector 88. A fixed frame 81 is slidably connected between two chutes. An electric push rod 83 is fixedly connected in the mounting opening in the middle of the upper end of the fixed frame 81. A connecting rod 84 is provided at the lower end of the telescopic end of the electric push rod 83. The middle of the connecting rod 84 is slidably connected to the sliding opening at the bottom end of the fixed frame 81. A detector 88 is inserted at the lower end of the connecting rod 84. The measuring mechanism 8 further includes a rack 82. A rack 82 is provided on the right side of the fixed frame 81. A motor 6 is provided at the front end of the mover seat of the linear motor 4 on the right side. A gear 7 is provided at the rear end of the output shaft of the motor 6. The gear 7 is meshed with the rack 82. The input end of the motor 6 is electrically connected to the output end of the single-chip microcomputer 3. The measuring mechanism 8 further includes a measuring scale 85 and a pointer 86. A measuring scale 85 is provided at the right end of the fixed frame 81. The pointer 86 is provided at the upper end of the connecting rod 84. The connecting rod 84 and the measuring scale 85 are corresponding in the left-right position. The measuring mechanism 8 further includes a fixing component 87. The fixing component 87 includes a locking groove 871, a top block 872 and a locking strip 874. A slot is formed at the bottom of the connecting rod 84. A top block 872 is slidably connected in the slot. Uniformly distributed locking grooves 871 are formed on the surface of the slot. A locking strip 874 is provided at the upper end of the detector 88. The locking strip 874 is cooperatively installed with the locking groove 871. The fixing component 87 further includes a spring 873. A spring 873 is provided between the top wall of the slot and the upper end of the top block 872. A locking strip 874 is provided on the detection rod of the detector 88. By inserting the locking strip 874 at the bottom of the connecting rod 84, the detection control panel of the detector 88 can be set inside the cabinet 1 according to requirements. Then, the motor 6 is turned on through the single-chip microcomputer 3. The rotation of the output shaft of the motor 6 drives the gear 7 to rotate. The gear 7 drives the rack 82 to move downward, and finally drives the fixed frame 81 to move downward. When the fixed frame 81 moves to the upper end of the water surface, the electric push rod 83 is turned on through the single-chip microcomputer 3. The telescopic end of the electric push rod 83 extends outward and pushes the connecting rod 84 downward. The connecting rod 84 drives the detector 88 to enter the water. At the same time, the pointer 86 moves downward synchronously. During the downward movement, pay attention to observing the depth at which the pointer 86 aligns with the measuring scale 85. When the detector 88 enters the depth to be detected, the electric push rod 83 can be turned off through the single-chip microcomputer 3. After the detection is completed, the above operations can be repeated in the reverse order to retract the detector 88 into the cabinet. When the detector 88 has been used for a period of time, the detector 88 can be removed for maintenance to ensure the detection accuracy. The detector 88 can be pushed upward. Pushing the detector 88 upward causes the detector 88 to move upward and squeeze the top block 872. The top block 872 squeezes the spring 873 to cause the spring 873 to contract. At this time, the detector 88 is rotated clockwise to make the locking strip 874 turn to one side of the vertical locking groove 871. At this time, the detector 88 can be pulled out. After the maintenance is completed, the above operations can be repeated in the reverse steps. The depth of measurement can be adjusted. After the measurement is completed, the detector 88 can be retracted to prevent microorganisms from attaching and affecting the measurement accuracy, and the detector 88 is convenient for disassembly and maintenance;

[0028] Wherein: the input end of the single-chip microcomputer 3 is electrically connected to an external power supply, and the input ends of the electric push rod 83, the linear motor 4 and the detector 88 are respectively electrically connected to the output end of the single-chip microcomputer 3.

[0029] The working principle of a water flow velocity measuring device for water conservancy detection provided by the present utility model is as follows: When there is a need to measure the water flow velocity in a certain area, the water flow velocity measuring staff needs to first fix the cabinet 1 at a suitable position through the fixing feet, and then turn on the single-chip microcomputer 3 to start the linear motor 4 through the single-chip microcomputer 3, so that the moving seat of the linear motor 4 drives the measuring mechanism 8 to move backward to the upper end of the avoidance port 5. Then, the motor 6 is turned on through the single-chip microcomputer 3. The output shaft of the motor 6 rotates to drive the gear 7 to rotate, and the gear 7 drives the rack 82 to move downward, and finally drives the fixing frame 81 to move downward. When the fixing frame 81 moves to the upper end of the water surface, the electric push rod 83 is turned on through the single-chip microcomputer 3. The telescopic end of the electric push rod 83 extends outward and pushes the connecting rod 84 downward. The connecting rod 84 drives the detector 88 to enter the water. At the same time, the pointer 86 moves downward synchronously. During the downward movement, pay attention to observing the depth at which the pointer 86 aligns with the measuring scale 85. When the detector 88 enters the depth to be detected, the electric push rod 83 can be turned off through the single-chip microcomputer 3. After the detection is completed, repeat the above operations in the reverse order to retract the detector 88 into the cabinet. When the detector 88 has been used for a period of time, the detector 88 can be removed for maintenance to ensure the detection accuracy. The detector 88 can be pushed upward. Pushing the detector 88 upward causes the detector 88 to move upward and squeeze the top block 872. The top block 872 squeezes the spring 873 to make the spring 873 contract. At this time, rotate the detector 88 clockwise to make the locking bar 874 turn into one side of the vertical locking groove 871. At this time, the detector 88 can be pulled out. After the maintenance is completed, repeat the above operations in the reverse steps.

[0030] It should be noted that in the above embodiments, the single-chip microcomputer 3 can be selected from the 51 series, the electric push rod 83 can be selected as JC35FA20A, the detector 88 can be selected as the FM-210V5 flow velocity sensor, the linear motor 4 can be selected as the DDL linear motor, and the motor 6 can be selected as 110BYGH1.8. The single-chip microcomputer 3 controls the electric push rod 83, the linear motor 4 and the motor 6 to work by using the commonly used methods in the prior art.

[0031] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be included in the patent protection scope of the present utility model by the same token.
