Description

Technical Field

[0001] The utility model relates to a mechanism for measuring water depth, belonging to the technical field of water detection devices. Background Technique

[0002] In water body monitoring research, the exploration of water depth is also an important monitoring index. In the prior art, a variety of devices for detecting water depth have also been designed. For example, the utility model patent with the patent number 202320899972 (a water area depth detection device) discloses a water area depth detection device equipped with a counterweight cone, a winding box, a positioning tube, and a positioning column. The counterweight devices in the prior art are suitable for relatively static water areas. For water areas with flowing water such as rivers and oceans, although there is a counterweight cone, it is inevitable that due to the flow of the water body, the counterweight cone is also prone to deviate from the vertical direction of the sinking position underwater, resulting in measurement deviation. How to measure the water depth more accurately is a problem studied in this field. Content of the Utility Model

[0003] In order to solve the problems in the prior art, a mechanism for measuring water depth is provided. The water depth is determined by the pressure situation detected by a pressure sensor, and a sampling motor is set to achieve water sample collection at different depths.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A mechanism for measuring water depth includes a base. An activity bracket is installed above the base through a lateral movement device. The special feature is that the activity bracket includes a base, a vertical plate installed on the base, and a horizontal plate installed on the upper part of the vertical plate; a wire hole is arranged at the bottom of the vertical plate, and a wire wheel is installed in the wire hole; the wire wheel is installed on the base through support columns on both sides. The vertical plate is hinged and installed with a wire release control rod on one side of the wire wheel, and a measuring rope is wound around the wire wheel; a lifting pulley with a lifting function is installed on the horizontal plate; the measuring rope on the wire wheel bypasses the wire wheel and then bypasses the lifting pulley and a suspension assembly is installed at the end; the suspension assembly includes a device bin, a water quality collection bin, a pressure sensor, and a protective shell; electronic devices for signal transmission are installed in the device bin.

[0006] The advantages of the above technical solution are: a suspension assembly is installed at the end of the measuring rope on the wire wheel. The measuring rope bypasses the wire wheel and the lifting pulley. The rotation of the wire wheel is controlled by the wire release rod. The suspension assembly enters the water under the action of gravity. The pressure sensor in the suspension assembly can detect the pressure at different depths, and the actual vertical depth can be determined through water depth conversion; and the offset distance of the suspension assembly can be calculated according to the length of the measuring rope.

[0007] Based on the above technical solutions, the present application makes the following improvements and enhancements to the above technical solutions:

[0008] Further, the lateral movement device includes a motor and a slide rail. The output shaft of the motor is installed with a lead screw through a coupling. Both ends of the lead screw are installed on the base through bearing seats. A slider that cooperates with the slide rail and an internally threaded block that cooperates with the lead screw are installed below the base.

[0009] The beneficial effect of the above technical feature in the present application is that the position of the movable bracket can be adjusted through the lateral movement device, which facilitates adjusting the water entry position of the suspension assembly.

[0010] Further, a length counter is installed on the vertical plate, and the distance measuring wheel of the length counter contacts the measuring rope.

[0011] The beneficial effect of the above technical feature in the present application is that the length counter is used to measure the length of the measuring rope entering the water.

[0012] Further, a wire winding assembly is also installed on the base; the wire winding assembly includes a wire winding motor. The output shaft of the wire winding motor is connected to a gearbox with a clutch. A pulley A is installed on the output shaft of the gearbox. A pulley B is installed at the end of the rotating shaft of the wire reel. Pulley A and pulley B are connected by a belt.

[0013] The beneficial effect of the above technical feature in the present application is that when wire winding is required, pull the handle on the clutch, and then the measuring rope can be wound up by starting the wire winding motor to retract the suspension assembly.

[0014] Further, the wire releasing control rod includes a long rod. A horizontal pressing plate is installed on the long rod. Clamping blocks with card slots are installed at both ends of the horizontal pressing plate. The clamping blocks are clamped on the circular plate of the wire reel.

[0015] The beneficial effect of the above technical feature in the present application is that the clamping blocks on the horizontal pressing plate are buckled on the spool plates on both sides of the wire reel. Lift the long rod, and the clamping blocks are separated from the wire reel. The measuring rope is released under the pulling of the suspension assembly. When it reaches the required depth, press down the long rod to press the clamping blocks on the rope wheel to restrict the rotation of the rope wheel and stop the wire release.

[0016] Further, a rubber pad is provided in the card slot of the clamping block.

[0017] The beneficial effect of the above technical feature in the present application is that a rubber pad is used to increase the friction between the clamping block and the wire reel.

[0018] Furthermore, the pulley with lifting function includes a pulley installed on a suspension rod. A sphere is provided at the end of the suspension rod, and the sphere on the suspension rod is installed within a connection assembly. The connection assembly includes an upper connector and a lower connector which are fixedly connected and have a spherical space inside. The lower connector is also provided with an axial through-hole. The upper connector is installed at the end of a threaded rod, the threaded rod is installed within an internal thread sleeve, and the internal thread sleeve is installed on a cross plate. The other end of the threaded rod is installed with an adjusting handwheel.

[0019] The beneficial effects of the above technical features in this application are as follows: By rotating the handwheel, the threaded rod rotates within the internal thread sleeve to achieve the lifting of the pulley. The inner cavity of the connection assembly is spherical, so that the sphere on the suspension rod can rotate within the cavity. When the threaded rod rotates, it can prevent the measuring rope from being wound due to the rotation of the suspension rod.

[0020] Furthermore, a test tube placement shell is installed inside the water quality collection bin. A motor bin is provided at the center of the test tube placement shell, and a plurality of test tube cavities are arranged around the motor bin. A battery and a sampling motor are installed inside the motor bin. A sampling cover is installed on the output shaft of the sampling motor, and a water inlet hole is provided on the sampling cover.

[0021] The beneficial effects of the above technical features in this application are as follows: Through the water quality collection bin, the sampling motor can be started at different depths. The sampling motor is a stepper motor. The sampling motor controls the rotation of the sampling cover. Each time it rotates, the water inlet hole corresponds to the test tube mouth at one position to achieve water sampling. The test tubes at other positions are covered by the sampling cover and do not participate in the water sample collection at this depth.

[0022] Furthermore, a display device is provided on the vertical plate.

[0023] The beneficial effects of the above technical features in this application are as follows: A microprocessor is provided inside the display device. The display device is electrically connected to a counter and a pressure sensor, and is also electrically connected to the sampling motor. The microprocessor inside the display device can calculate the water depth according to the information received from the pressure sensor through a pre-set program, and can simultaneously display the length information of the measuring rope measured by the counter. At the same time, it is also used to control the sampling motor. Description of the Drawings
