Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy and hydrological survey instruments, and in particular relates to a multifunctional portable sounding rod. Background Art

[0002] The sounding rod is one of the main tools for water depth measurement. In hydrological research, we usually need to measure the water depth and related information such as flow velocity at relative water depths of 0.2, 0.6, and 0.8. Traditional wading tests require three people to perform them simultaneously, where employee No. 1 uses a sounding rod to measure the standard depth of the water, employee No. 2 records the standard depth measured by employee No. 1 and multiplies it by a relative coefficient to calculate the relative water depth where the current meter should be placed under the water surface, employee No. 3 places the side velocity hanging rod equipped with the current meter at the relative depth of the current meter under the water surface calculated by employee No. 2, and employee No. 2 begins to record the measurement time and measurement data according to the position of the side velocity hanging rod. This method requires more measuring instruments, which are not convenient to carry, and requires cooperation of multiple people to complete the measurement. The measurement is difficult and requires more human resources. In addition, due to the delay in manual calculation or operation, the flow velocity at the relative water depths of 0.2, 0.6, and 0.8 is not the same time, making it difficult to ensure the accuracy of the measurement, resulting in large measurement errors.

One end of the fixing rod is fixed to the middle of the upper end surface of the device shell, and the other end of the fixing rod is welded and fixed to the handle ring. A controller, a driving mechanism, a positioning module and an information storage module are fixed on the top plate 113 in the device shell 21. The positioning module is communicatively connected with the information storage module through wires. The positioning module will send real-time position information of the control unit to the information storage module through wires. The driving mechanism and the information storage module are control-connected to the controller through wires. The controller can drive the control driving mechanism and the information storage module to start working. The controller is connected to the control panel through wires to form a depth measuring rod control system.

[0031] like Figure 4 , Figure 6 As shown, the second measuring slide 14, the third measuring slide 15 and the fourth measuring slide 16 of the fixed frame frame are all provided with a vertical threaded screw 6, the lower end of the threaded screw 6 is vertically rotated and fixed on the bottom plate, and the upper end of the threaded screw is vertically rotated and fixed on the top plate and passes through the top plate to be transmission-connected with the driving mechanism, specifically: Figure 4 As shown, the middle parts of the top plate 113 and the bottom plate 114 located in the second measuring slide 14, the third measuring slide 15 and the fourth measuring slide 16 are vertically opened with through holes, and fixed bearings are installed in the through holes.

[0032] The driving mechanism includes a stepper motor and a power supply, which is fixed on the top plate 113. The first stepper motor 222, the second stepper motor 223 and the third stepper motor 224 are fixed in sequence at the middle of the upper end of the top plate 113 corresponding to the positions of the second measuring slide 14, the third measuring slide 15 and the fourth measuring slide 16.

The first stepper motor 222, the second stepper motor 223 and the third stepper motor 224 can be controlled by the controller to drive the corresponding threaded screw 6 to rotate horizontally in the measuring slide.

[0033] like Figure 8 As shown, the suspension rod group includes a main rod 121, a first auxiliary rod 123, a second auxiliary rod 125 and a third auxiliary rod 127. The heights of the first auxiliary rod 123, the second auxiliary rod 125 and the third auxiliary rod 127 are 0.8 times, 0.6 times and 0.2 times the height of the main rod 121 respectively. The main rod and the auxiliary rod are all fan-column structure rods. The middle parts of the first auxiliary rod 123, the second auxiliary rod 125 and the third auxiliary rod 127 are vertically provided with threaded through holes 17 penetrating the rod body. The main rod 121 is fixedly embedded in the first measuring slide 13, and a main scale 122 for measuring water depth is engraved on the outer end surface of the main rod 121. The auxiliary rod 123, the second auxiliary rod 125 and the third auxiliary rod 127 are matched and mounted on the threaded screw 6 in the second measuring slide 14, the third measuring slide 15 and the fourth measuring slide 16 respectively, and the left and right end surfaces of the auxiliary rods in the measuring slides are respectively in contact with the two side walls of the corresponding measuring slides. When the threaded screw 6 in the measuring slides rotates, since the left and right end surfaces of the auxiliary rods on the threaded screw 6 are in contact with the two side walls of the measuring slides, the auxiliary rods mounted on the threaded screw 6 cannot rotate in the measuring slides with the threaded screw 6, and can only move vertically up and down along the two side walls of the measuring slides based on the rotation of the threaded screw 6.

[0034] The first auxiliary rod 123, the second auxiliary rod 125 and the third auxiliary rod 127 are respectively engraved with the first auxiliary scale 124, the second auxiliary scale 126 and the third auxiliary scale 128 on their outer end surfaces. The actual length values ​​of each scale unit of the scale division values ​​of the first auxiliary scale 124, the second auxiliary scale 126 and the third auxiliary scale 128 are respectively 0.8, 0.6 and 0.2 times of the standard value. When the first auxiliary rod 123, the second auxiliary rod 125 and the third auxiliary rod 127 in the second measuring slide 14, the third measuring slide 15 and the fourth measuring slide 16 are driven by the driving mechanism to slide up and down along the measuring slides, the auxiliary scales on the auxiliary rods and the main scale on the main rod can have the same scales in the horizontal plane.

[0035] The outer end surfaces of the first auxiliary rod 123, the second auxiliary rod 125 and the third auxiliary rod 127 are provided with a flow measuring assembly 7 for measuring the water flow velocity at the bottom end of the outer end surface of the auxiliary rod. The flow measuring assembly includes a mounting seat and a flow meter. The mounting seat is fixedly connected to the auxiliary rod by bolts. The flow meter is matched and mounted on the mounting seat. The flow measuring hole of the flow meter is on the same horizontal plane as the 0 scale line of the auxiliary scale on the corresponding auxiliary rod. The flow meter is communicatively connected to the information storage module via wires.

[0036] like Fig.11As shown, the sounding rod of this embodiment is used in wading test work. First, the sounding rod of this embodiment is assembled. When not in use, the 0 scale line of the auxiliary scale on the auxiliary rod and the 0 scale line of the main scale on the main rod are on the same horizontal plane. Then, a single person holds the handle to lift the sounding rod and places it in the water flow to be detected, so that the bottom plate 111 extends into the mud at the bottom of the water. The sounding rod control system on the sounding rod is started by operating the control panel, and then the water depth measured by the main scale 122 on the main rod 121 of the sounding rod is observed, and the observed water depth is input into the control panel. Then, the start button of the control panel is clicked, and the control panel sends a digital signal to the controller of the sounding rod control system. After receiving the digital signal, the controller will The first stepper motor 222, the second stepper motor 223 and the third stepper motor 224 are respectively controlled to drive the first auxiliary rod 123, the second auxiliary rod 125 and the third auxiliary rod 127 to move upward along the measuring slideway to a corresponding height, and to make the scale lines of the auxiliary scales on the first auxiliary rod 123, the second auxiliary rod 125 and the third auxiliary rod 127 with the same water depth size as the main scale to be on the same horizontal plane. After the controller controls the stepper motor to complete the moving action according to the digital signal, the controller will send a completion signal to the control panel. After the control panel receives the movement completion signal, the indicator light corresponding to the start button will emit a green light. Since the scale division values ​​of the auxiliary scales on the first auxiliary rod 123, the second auxiliary rod 125 and the third auxiliary rod 127 are equal to each moment, the controller will send a completion signal to the control panel. After the control panel receives the movement completion signal, the indicator light corresponding to the start button will emit a green light. The actual length values ​​of the degree unit are 0.8, 0.6 and 0.2 times of the standard value respectively. Therefore, at this time, the flow measuring components on the first auxiliary rod 123, the second auxiliary rod 125 and the third auxiliary rod 127 are respectively located at the relative depth positions of the water flow corresponding coefficients. There is no need to manually calculate the relative depth size. The operation is convenient and can be completed by one person. When the operator observes that the indicator light corresponding to the start button will emit a green light, the operator clicks the store button on the control panel, and the control panel will send a start side flow command to the controller. After receiving the side flow command, the controller will control the positioning module, the information storage module and the flow measuring instruments on each auxiliary rod to start working at the same time. The positioning module sends the real-time position information of the sounding rod to the information storage module. After the flow meter on the auxiliary rod starts working, it will transmit the measured flow rate data of water flows at different relative depths to the information storage module. After receiving the data transmitted by each flow meter, the information storage module will store the measurement data in combination with the real-time position information sent by the positioning module. After the information storage module completes the storage of the measurement data, it will send a measurement completion signal to the controller. After receiving the measurement completion signal, the controller will send a measurement completion signal to the control panel. After the control panel receives the measurement completion signal, the indicator light corresponding to the storage button on the control panel will emit green light. At this time, the test is completed. Since the information storage module simultaneously stores the flow rate data of water flows at different relative depths, the measurement data is more accurate.

[0037] The portable multifunctional sounding rod provided in the embodiment of the present invention has a simple structure and is easy to carry. A single person can operate the sounding rod to measure the flow velocity at a relative water depth, and the water flow velocity at a relative depth can be directly obtained and recorded through the detection rod, thereby solving the problem of needing to use multiple instruments, requiring cooperation of multiple people, and having large measurement errors when conducting wading tests.

[0038] Example 2

[0039] The difference between Example 2 and Example 1 is that the model of the control panel is different.

[0040] A water depth detector is installed in the device housing 21, and the water depth detector is connected to the controller through wires. Fig.12 As shown, an electric water level detection line 9 corresponding to the main scale is fixed on the outer end surface of the main rod. The electric water level detection line 9 is connected to the water depth detector. When in use, the water depth detector can directly measure the water depth through the electric water level detection line and send a digital signal to the controller.

[0041] The sounding rod of this embodiment is used in wading test work. First, the sounding rod of this embodiment is assembled. When not in use, the 0 scale line of the auxiliary scale on the auxiliary rod and the 0 scale line of the main scale on the main rod are on the same horizontal plane. Then, one person holds the handle to lift the sounding rod and place it in the water flow to be detected, so that the bottom plate 111 extends into the mud at the bottom of the water, and then controls it as shown in the figure. Fig.10The control panel shown in the figure has a start button on the motor control panel. The control panel will send a working command to the controller. After receiving the working command, the controller will control the water depth detector to start working. After the water depth detector starts working, it will directly measure the water depth through the electric water level detection line and send a digital signal corresponding to the measured water depth to the controller. When the controller receives the digital signal, it will control the first stepper motor 222, the second stepper motor 223 and the third stepper motor 224 according to the digital signal to drive the first auxiliary rod 123, the second auxiliary rod 125 and the third auxiliary rod 127 to move upward along the measuring slideway to a corresponding height, and make the scale lines on the auxiliary scales of the first auxiliary rod 123, the second auxiliary rod 125 and the third auxiliary rod 127 with the same water depth as the main scale on the same horizontal plane. After the controller controls the stepper motor to complete the moving action according to the digital signal, the controller will send a completion signal to the control panel. After the control panel receives the movement completion signal, the indicator light corresponding to the start button will emit a green light. Light, when the operator observes that the indicator light corresponding to the start button will emit green light, the operator clicks the store button on the control panel, and the control panel will send a start side flow command to the controller. After receiving the side flow command, the controller will control the positioning module, the information storage module and the current meters on each auxiliary rod to start working at the same time. The positioning module sends the real-time position information of the sounding rod to the information storage module. After the current meters on each auxiliary rod start working, they will transmit the measured flow velocity data of the water flow at different relative depths to the information storage module. After receiving the data transmitted by each current meter, the information storage module will store the measurement data in combination with the real-time position information sent by the positioning module. After the information storage module completes the storage of the measurement data, it will send a measurement completion signal to the controller. After receiving the measurement completion signal, the controller will send a measurement completion signal to the control panel. After the control panel receives the measurement completion signal, the indicator light corresponding to the store button on the control panel will emit green light, and the test is completed at this time.

[0042] Compared with the sounding rod provided in Example 1, the sounding rod provided in this embodiment does not require manual reading of the water depth dimension and manual input of the water depth dimension to send a digital signal to the controller when in use, and is more convenient to use.
