Description

Technical Field

[0001] The present invention belongs to the technical field of accessories for water body detection equipment, and particularly relates to a water body transparency measuring device. Background Art

[0002] Water body transparency is also one of the main indicators for evaluating the trophic status of lakes and reservoirs in China. At present, the detection methods for water body transparency include the lead letter method, the cross method, and the Secchi disk method. Among them, the Secchi disk method is the most commonly used on-site water body transparency detection method. In this method, a white disk is vertically placed into the water until it can no longer be seen. The depth at which the white disk disappears is the transparency. The Secchi disk method is simple and intuitive.

[0003] This detection method requires the transparency disk to be placed in the water. During the actual detection process, relevant personnel need to place the transparency disk into the water body to be measured through a pull rope, and then perform relevant measurements. In this measurement method, a pull rope needs to be set on the transparency disk, and the measurement personnel measure the transparency disk through the pull rope. Therefore, this measurement method relies on manual work, with low measurement efficiency and low measurement accuracy. Summary of the Invention

[0004] The present invention provides a water body transparency measuring device, aiming to solve the problems of low measurement efficiency and low measurement accuracy of existing water body transparency measuring devices.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0006] A water body transparency measuring device includes a floating frame, on which a transparency measuring disk is provided, and a sighting rod for facilitating the identification of the position of the water body transparency measuring device is provided on the transparency measuring disk;

[0007] A counterweight mechanism is provided below the floating frame to immerse a part of the transparency measuring disk into the water body to be measured through the floating frame. The counterweight mechanism includes a non-counterweight state and a counterweight state. When the counterweight mechanism is in the non-counterweight state, the transparency measuring disk floats on the water body to be measured. When the counterweight mechanism is in the counterweight state, a part of the transparency measuring disk is immersed in the water body to be measured;

[0008] A depth detector for measuring the position of the transparency disk relative to the bottom of the water body to be measured is further provided on the floating frame. The depth detector measures the depth once when the counterweight mechanism is in the non-counterweight state and once when it is in the counterweight state;

[0009] A controller is also provided on the floating frame. Both the depth detector and the counterweight mechanism are controlled by the controller to operate. A memory and a comparator are integrated in the controller. An alarm is also provided on the floating frame. The memory records the two measurement results of the water transparency measuring device at the same position. The comparator compares the two measurement results of the same position recorded in the memory. When the two measurement results of the same position are greater than the set value, the controller controls the alarm to operate.

[0010] Further improved solution: A locator for positioning the position of the floating frame is also provided on the floating frame. The locator is adhered to the floating frame and is communicatively connected to the controller.

[0011] Based on the above technical solution: By providing a locator, the locator can conveniently locate the current position of the floating frame, so that relevant personnel can timely understand whether the current position of the floating frame is the measurement position.

[0012] Further improved solution: A communicator is also provided on the floating frame. The communicator is communicatively connected to the controller, and the communicator transmits the data obtained by the locator and the depth detector.

[0013] Based on the above technical solution: By providing a communicator, the data obtained by the water transparency measuring device and the data generated by other electronic devices on the floating frame can be conveniently sent out, so that the measurement personnel can remotely obtain the data.

[0014] Further improved solution: The water transparency measuring device further includes a portable electronic device, and the portable electronic device receives the data transmitted by the communicator.

[0015] Based on the above technical solution: By providing a portable electronic device, relevant personnel can obtain the data sent by the communicator at any location with network.

[0016] Further improved solution: The depth detector includes a signal generator for emitting a detection signal and a signal receiver for receiving the detection signal reflected from the bottom of the water body to be measured. Both the signal generator and the signal receiver are communicatively connected to the controller.

[0017] Based on the above technical solution: The depth detector has a simple structure and high measurement accuracy.

[0018] Further improved solution: A thruster for pushing the floating frame to displace in the water body to be measured is also provided on the floating frame. The thruster includes a propulsion cover, a diaphragm pump is provided below the propulsion cover, and a reversing valve is provided between the diaphragm pump and the propulsion cover;

[0019] The cross-sectional shape of the propulsion cover is circular. A partition is provided inside the propulsion cover, and the partition divides the propulsion cover into four propulsion chambers. Two opposite propulsion chambers are symmetrically arranged with respect to the axis of the propulsion cover. A through groove for communicating the propulsion chamber with the outside is also provided on the side wall of the propulsion cover. The through groove is strip-shaped, and the through groove is arranged along the axis direction of the propulsion cover;

[0020] The reversing valve connects two opposite propulsion chambers, and the diaphragm pump supplies the liquid in one of the two opposite propulsion chambers into the other propulsion chamber.

[0021] Based on the above technical solution: During use, the propulsion device is placed in the liquid, and the propulsion device floats in the water body. Control to connect two opposite propulsion chambers, and then turn on the diaphragm pump. The diaphragm pump supplies the liquid in one propulsion chamber into the other propulsion chamber. Since the volume of the propulsion chamber is certain, one propulsion chamber absorbs water, and the other propulsion chamber sprays water out through the through groove. When the propulsion chamber sprays water out through the through groove, a reaction force is generated to displace the propulsion device.

[0022] When the propulsion device needs to turn, only need to operate the control valve to connect another pair of propulsion chambers. Since two adjacent propulsion chambers are at different angles, when another pair of propulsion chambers are connected, under the action of the diaphragm pump, the thruster can complete the turning.

[0023] The propulsion chamber sprays water out through the through groove to generate a reaction force, which can effectively push the propulsion device to displace. At the same time, the propulsion chamber can be conveniently arranged on the propulsion cover, so that when different propulsion chambers spray water out, corresponding thrust can be generated to turn the propulsion device. Using different propulsion chambers to spray water to turn the propulsion device effectively reduces the turning radius of the propulsion device.

[0024] Further improved solution: A guiding piece is also provided on the propulsion cover. The guiding piece is disc-shaped, and the axis of the guiding piece coincides with the axis of the propulsion cover.

[0025] Based on the above technical solution: By providing the guiding piece, the guiding piece plays a guiding role to prevent the floating frame from tipping over when displaced by the thruster.

[0026] Further improved solution: The guiding piece is fixed to the propulsion cover by screws. The guiding piece is provided with a flange for installing the screws. The propulsion cover includes an upper part and a lower part. The heights of the upper part and the lower part are equal. The guiding piece is located between the upper part and the lower part. Through grooves are provided on both the upper part and the lower part.

[0027] Based on the above technical solution: The guiding piece is easy to assemble with the propulsion cover, so that the thruster is easy to maintain.

[0028] Further improved solution: The counterweight mechanism includes a housing, a cavity is arranged inside the housing, a piston is arranged inside the cavity, the piston divides the cavity into an upper cavity in a sealed state and a lower cavity communicating with the water body, and a position adjustment mechanism for adjusting the position of the piston inside the cavity is arranged inside the upper cavity;

[0029] The position adjustment mechanism includes a lead screw, the lead screw is arranged in the vertical direction, and the axis of the lead screw coincides with the axis of the inscribed circle of the housing. A nut seat matching with the lead screw is arranged on the piston, the nut seat is arranged on the piston through a connecting plate, and a guiding mechanism for guiding the nut seat is also arranged inside the cavity.

[0030] Based on the above technical solution: During the use process, first move the piston away from the upper end of the housing. At this time, the upper cavity has the largest volume and the lower cavity has the smallest volume. During the displacement of the piston towards the lower end of the housing, air can enter the upper cavity through the piston. A one-way valve can also be arranged inside the upper cavity to allow air to enter the upper cavity through the one-way valve.

[0031] The counterweight force of the counterweight device depends on the size of the volume of the upper cavity. The larger the volume of the upper cavity, the larger the volume of air in the counterweight device, and the smaller the overall density of the counterweight device. The smaller the volume of the upper cavity, the larger the volume of the lower cavity. At this time, more water will enter the lower cavity, thereby increasing the overall density of the counterweight device.

[0032] When it is necessary to change the counterweight force of the counterweight device, rotate the lead screw to move the piston upward or downward. At this time, the volume of the upper cavity decreases or increases, so that the counterweight force of the counterweight device is within a reasonable range.

[0033] By arranging the piston and the lead screw, the position of the piston can be adjusted inside the cavity, so that the volumes of the upper cavity and the lower cavity can be adjusted, and further the counterweight force of the counterweight device can be conveniently adjusted.

[0034] Further improved solution: A motor for driving the rotation of the lead screw is also arranged inside the cavity. The motor includes an output shaft, the motor drives the rotation of the lead screw through the output shaft, the output shaft and the lead screw are of an integral structure, the motor is fixed to the housing by screws, and the motor is arranged inside the upper cavity.

[0035] Based on the above technical solution: The motor is arranged inside the upper cavity, and the liquid will not damage the motor.

[0036] The beneficial effects of the present invention are:

[0037] In actual use, first place the water transparency measuring device in the water body to be measured. The floating rod is convenient for identifying the location of the water transparency measuring device. Then, through the controller, the depth detection device completes the first depth detection. Then, through control, the counterweight mechanism works. The counterweight mechanism working makes the transparency measuring disc slowly sink into the water body to be measured until the black and white colors on the black and white panel disc cannot be distinguished.

[0038] Then, through the controller, the depth detection device completes the second depth detection. By comparing the depth differences between the first test detection and the second depth detection and through conversion, the water transparency value of the water body to be measured can be obtained.

[0039] By setting the controller, the counterweight mechanism and the depth detector, when measuring the water transparency, there is no need for too much human intervention, which improves the measurement efficiency and measurement accuracy of the water transparency.

[0071] The reversing valve 93 connects two opposite propulsion chambers 95. And the diaphragm pump 92 supplies the liquid in one of the two opposite propulsion chambers 95 into the other propulsion chamber 95.

[0072] Using a diaphragm pump 92 does not require a filter screen, and the diaphragm pump 92 has lower requirements for impurities in the water, thus making the propulsion device easy to maintain. The propulsion cover 91 can be fixed to the floating frame 1 by threads.

[0073] In order to make the propulsion device have better stability during displacement, based on the above embodiments: A guiding piece 97 is further provided on the propulsion cover 91.

[0074] The guiding piece 97 is fixed to the propulsion cover 91 by screws, and a flange for installing the screws is provided on the guiding piece 97.

[0075] The propulsion cover 91 includes an upper part and a lower part. The heights of the upper part and the lower part are equal. The guiding piece 97 is located between the upper part and the lower part. Through grooves 96 are provided on both the upper part and the lower part.

[0076] The guiding piece 97 can also be an integral structure with the propulsion cover 91.

[0077] In order to prevent the liquid in the propulsion chamber 95 from leaking easily, based on the above embodiments: The partition plate 94 includes a plate body and a column body provided in the propulsion cover 91. The plate body and the column body are of an integral structure, and the column body and the propulsion cover 91 are of an integral structure. The propulsion chambers 95 are formed between adjacent two plate bodies.

[0078] A cover plate is provided at the lower end of the propulsion cover 91. The cover plate is fixed to the propulsion cover 91 by threads, and a sealing ring is provided between the cover plate and the propulsion cover 91.

[0079] A through hole is provided on the cover plate, and the reversing valve 93 communicates with the propulsion chamber 95 through the through hole.

[0080] The reversing valve 93 is fixed to the cover plate, a sealing ring is provided between the reversing valve 93 and the cover plate, and the diaphragm pump 92 is fixed to the cover plate through the reversing valve 93.

[0081] The reversing valve 93 can be a four-way four-position solenoid valve.

[0082] Embodiment 4:

[0083] In order to facilitate the machining of the counterweight mechanism 3, on the basis of the above embodiment, the counterweight mechanism 3 includes a housing 31. A cavity 32 is provided inside the housing 31. A piston 33 is provided inside the cavity 32. The piston 33 divides the cavity 32 into an upper cavity 321 in a sealed state and a lower cavity 322 communicating with the water body. A position adjusting mechanism 34 for adjusting the position of the piston 33 inside the cavity 32 is provided inside the upper cavity 321.

[0084] The position adjusting mechanism 34 includes a lead screw 341. The lead screw 341 is arranged in the vertical direction, and the axis of the lead screw 341 coincides with the axis of the inscribed circle of the housing 31. A nut seat 342 cooperating with the lead screw 341 is provided on the piston 33. The nut seat 342 is arranged on the piston 33 through a connecting plate 343. A guiding mechanism 344 for guiding the nut seat 342 is further provided inside the cavity 32.

[0085] A one-way valve can also be provided on the housing 31. The one-way valve is connected and communicated with the upper cavity 321, so that air can enter the upper cavity 321 through the one-way valve. Air can also enter the upper cavity 321 through the piston 33. At this time, when the piston 33 moves downward, the lower cavity 322 should not be communicated with the water body.

[0086] During use, the propulsion device is placed in the liquid, and the propulsion device floats in the water body. Control to connect two opposite propulsion chambers 95, and then turn on the diaphragm pump 92. The diaphragm pump 92 supplies the liquid in one propulsion chamber 95 into the other propulsion chamber 95. Since the volume of the propulsion chamber 95 is certain, therefore, one propulsion chamber 95 absorbs water, and the other propulsion chamber 95 sprays water outward through the through groove 96. When the propulsion chamber 95 sprays water outward through the through groove 96, a reaction force is generated to displace the propulsion device.

[0087] When the propulsion device needs to turn, only the control valve needs to be operated to connect another pair of propulsion chambers 95. Since adjacent two propulsion chambers 95 are at different angles, when the other pair of propulsion chambers 95 are connected, under the action of the diaphragm pump 92, the thruster 9 can complete the turning.

[0088] The propulsion chamber 95 ejects water outward through the through groove 96 to generate a reaction force, which can effectively push the displacement of the propulsion device. At the same time, the propulsion chamber 95 can be conveniently arranged on the propulsion cover 91, so that when different propulsion chambers 95 eject water outward, corresponding thrust can be generated to make the propulsion device turn. Using different propulsion chambers 95 to eject water to make the propulsion device turn effectively reduces the turning radius of the propulsion device.

[0089] In order to simplify the structure of the position adjusting mechanism 34, on the basis of this embodiment: a motor for driving the rotation of the lead screw 341 is further arranged in the cavity 32. The motor includes an output shaft, and the motor drives the rotation of the lead screw 341 through the output shaft.

[0090] The output shaft and the lead screw 341 are of an integral structure. The motor is fixed to the outer shell 31 by screws, and the motor is arranged in the upper cavity 321.

[0091] In order to make the counterweight device have better stability and prevent the counterweight device from rotating along the vertical axis, the motor can also be arranged in the following way: an installation disk for installing the motor is arranged in the upper cavity 321. The axis of the output shaft is perpendicular to the axis of the lead screw 341. A counterweight body equal in weight to the motor is further arranged on the installation disk. The motor and the counterweight body are symmetrically arranged with respect to the symmetry center line of the installation disk. The output shaft drives the rotation of the lead screw 341 through a commutation mechanism.

[0092] The commutation mechanism includes a first bevel gear arranged on the output shaft and a second bevel gear arranged on the lead screw 341. The first bevel gear is engaged with the second bevel gear.

[0093] The installation disk can be fixed to the inside of the outer shell 31 by screws.

[0094] In order to further improve the stability of the counterweight device, on the basis of the above embodiment: the connecting plate 343 is in a cylindrical shape. The upper end of the connecting plate 343 is welded to the nut seat 342, and the lower end of the connecting plate 343 is welded to the piston 33. The axis of the connecting plate 343 coincides with the axis of the lead screw 341.

[0095] The guiding mechanism 344 includes a guiding column installed on the motor and a guiding hole provided on the nut seat 342. The guiding column and the motor are of an integral structure. There are at least three guiding columns, and the guiding columns are evenly arranged along the circumferential direction of the output shaft.

[0096] A sealing ring is provided between the piston 33 and the side wall of the cavity 32. The sealing ring is bonded to the piston 33, and there are at least two turns of the sealing ring.

[0097] Embodiment Five:

[0098] In order to prevent impurities from entering the lower cavity 322 and causing wear of the piston 33, on the basis of the above embodiment: a water inlet communicating with the lower cavity 322 is provided at the lower end of the outer shell 31.

[0099] A filter screen is provided in the water inlet. The filter screen is provided with an external thread, and an internal thread matching the external thread is provided in the water inlet.

[0100] During the use process, first move the piston 33 away from the upper end of the outer shell 31. At this time, the upper cavity 321 has the largest volume and the lower cavity 322 has the smallest volume. During the displacement of the piston 33 towards the lower end of the outer shell 31, air can enter the upper cavity 321 through the piston 33. A one-way valve can also be provided in the upper cavity 321 to allow air to enter the upper cavity 321 through the one-way valve.

[0101] The counterweight force of the counterweight device depends on the size of the volume of the upper cavity 321. The larger the volume of the upper cavity 321, the larger the air volume in the counterweight device, and the smaller the overall density of the counterweight device. The smaller the volume of the upper cavity 321, the larger the volume of the lower cavity 322. At this time, more water will enter the lower cavity 322, thereby increasing the overall density of the counterweight device.

[0102] When it is necessary to change the counterweight force of the counterweight device, rotate the lead screw 341 to move the piston 33 upward or downward. At this time, the volume of the upper cavity 321 decreases or increases, so that the counterweight force of the counterweight device is within a reasonable range.

[0103] By providing the piston 33 and the lead screw 341, the position of the piston 33 can be adjusted within the cavity 32, so that the volumes of the upper cavity 321 and the lower cavity 322 can be adjusted, and further the size of the counterweight force of the counterweight device can be conveniently adjusted.

[0104] The following further introduces a water transparency measuring device provided by the present invention in combination with the working principle:

[0105] In actual use, first place the water transparency measuring device in the water body to be measured. The floating rod 21 facilitates identifying the location of the water transparency measuring device. Then, through the controller 5, the depth detection device completes the first depth detection. Then, through control, the counterweight mechanism 3 works. The working of the counterweight mechanism 3 causes the transparency measuring disc 2 to slowly sink into the water body to be measured until the black and white colors on the black and white panel disc cannot be distinguished from each other.

[0106] Then, through the controller 5, the depth detection device completes the second depth detection. By comparing the depth differences between the first test detection and the second depth detection and through conversion, the water transparency value of the water body to be measured can be obtained.

[0107] By setting the controller 5, the counterweight mechanism 3, and the depth detector 4, when measuring the water transparency, there is no need for too much human intervention, which improves the water transparency measurement efficiency and measurement accuracy.

[0108] The present invention is not limited to the above optional implementation manners. On the premise of not conflicting with each other, the various solutions can be arbitrarily combined; anyone can obtain other various forms of products under the inspiration of the present invention. However, no matter what changes are made in its shape or structure, as long as the technical solutions fall within the scope defined by the claims of the present invention, they all fall within the protection scope of the present invention.
