One end of the threaded rod 24 is connected with the conductive sleeve 23 and is insulated from the conductive sleeve 23, the threaded rod 24 can drive the conductive sleeve 23 to slide on the lifting rod 22 under the drive of the motor 25, and the control circuit 26 is electrically connected with the motor 25, the first conductive rod, the second conductive rod and the conductive sleeve 23. When the water level of the river rises, the floating ball 21 drags the lifting rod 22 to enable the second conductive rod to be in contact with the conductive sleeve 23, so that the control circuit 26 controls the motor 25 to rotate to drive the threaded rod 24 to rotate to drive the conductive sleeve 23 to move upwards, and as the conductive sleeve 23 is connected with the shading sleeve 14 to drive the shading sleeve 14 to move upwards, when the conductive sleeve 23 is lifted to be in contact with the insulating rod, the control circuit 26 is disconnected, and the motor stops rotating; the rising distance of the floating ball 21 is equal to the rising distance of the conductive sleeve 23 and is also equal to the rising distance of the shading sleeve 14, so that the bottom of the shading sleeve 14 is always level with the water surface, light above the water surface can be always shielded, and the device can continuously measure the change of the distribution of the vertical lines of the sand content of the river in water.
Further, the control circuit 26 of the present embodiment includes a second power supply 261, a second switch 262, a first ferrous spring switch 263, a first electromagnet 264, a first protection resistor 265, a second ferrous spring switch 266, a second electromagnet 267, and a second protection resistor 268, the first ferrous spring switch 263 and the first protection resistor 265 are connected in series between one electrode of the motor 25 and a negative electrode of the second power supply 261, and the second ferrous spring switch 266 and the second protection resistor 268 are connected in series between the other electrode of the motor 25 and the negative electrode of the second power supply 261; the positive electrode of the second power supply 261 is connected with the conductive sleeve 23 through the second switch 262; one end of the first electromagnet 264 is connected with a first conducting rod, the other end of the first electromagnet 264 is connected to a wire connected with the first iron spring switch 263 and the motor 25, and the magnetic pole of the first electromagnet 264 faces the first iron spring switch 263; one end of the second electromagnet 267 is connected to a second conductive rod, and the other end of the first electromagnet 264 is connected to a conductive wire connected to the second iron spring switch 266 and the motor 25, wherein the magnetic pole of the second electromagnet 267 faces the second iron spring switch 266. When the river water level rises, the floating ball 21 drags the lifting rod 22 to enable the second conducting rod to be in contact with the conducting sleeve 23, so that the circuit from the second conducting rod, the second electromagnet 267, the second iron spring switch 266, the second protection resistor 268 and the second power supply 261 to the conducting sleeve 23 is conducted, at the moment, the second electromagnet 267 can adsorb the second iron spring switch 266 to enable the second iron spring switch 266 to be disconnected, and therefore current flows into the motor 25 from the second electromagnet 267, flows into the second power supply 261 after passing through the first iron spring switch 263 and the first protection resistor 265, and at the moment, the motor 25 positively rotates to enable the conducting sleeve 23 to rise. When the river water level drops, the floating ball 21 drives the lifting rod 22 to drop, so that the first conducting rod is in contact with the conductive sleeve 23, and the circuit from the first conducting rod, the first electromagnet 264, the first iron spring switch 263, the first protection resistor 265 and the second power source 261 to the conductive sleeve 23 is conducted, at this time, the first electromagnet 264 can adsorb the first iron spring switch 263 to disconnect the first iron spring switch 263, and thus, current flows into the motor 25 from the first electromagnet 264, flows into the second power source 261 after passing through the two iron spring switches and the two protection resistors, and at this time, the motor 25 is reversed to enable the conductive sleeve 23 to drop. It is noted that in both processes, when the conductive sleeve 23 is brought into full contact with the insulating rod, the circuit is broken and the motor 25 stops rotating. In the process of moving the conductive sleeve 23, the rod extending from the conductive sleeve 23 pulls the insulation string to synchronously lift the shading sleeve 14, so that the bottom end of the shading sleeve 14 is just contacted with the water surface all the time.
Still further, the support 27 of this embodiment is fixedly arranged, the motor 25 is mounted on the support 27, the second transmission gear 210 is coaxially and fixedly connected with the rotating shaft of the motor 25, the first transmission gear 29 is rotatably mounted on the support 27, the first transmission gear 29 is meshed with the second transmission gear 210, a threaded hole is formed in the middle of the first transmission gear 29, a threaded rod is inserted into the threaded hole, one end of the threaded rod 24 is fixedly connected with the polygonal limiting rod 28, a polygonal limiting hole is formed in the upper end of the support 27, and the polygonal limiting rod 28 is slidably inserted into the polygonal limiting hole. By gear engagement, the accuracy of the transmission can be improved, and at the same time, the threaded rod 24 can be prevented from rotating by the restriction of the polygonal stopper rod 28, thereby ensuring that the threaded rod 24 moves up and down.
Further, the water level monitoring cylinder 211 of this embodiment is divided into a front half cylinder body and a rear half cylinder body, wherein the front half cylinder body is a water facing surface, the rear half cylinder body is provided with a plurality of water inlet and outlet holes, and the floating ball 21 is placed in the water level monitoring cylinder 211. The water level monitoring cylinder 211 is fixedly arranged and is divided into a front half cylinder body and a rear half cylinder body, wherein the front half cylinder body is a water facing surface, the rear half cylinder body is a water facing surface, a plurality of water inlet and outlet holes are formed in the rear half cylinder body, and the floating ball 21 is placed in the water level monitoring cylinder 211. The water inlet and outlet holes are densely distributed on the back surface of the back half cylinder body of the cylinder wall of the water level monitoring cylinder, so that the phenomenon that the water level in the water level monitoring cylinder is higher due to the fact that the kinetic energy of water flow is converted into potential energy can be avoided. The number of the water inlet holes and the water outlet holes is enough, so that the sensing sensitivity of the water level monitoring cylinder to the water level change of the river channel can be increased. The wall of the water level monitoring cylinder has a certain thickness, the aperture of the water inlet and outlet hole is smaller, the holes of the water inlet and outlet hole are slender, the water level vibration in the water level monitoring cylinder caused by the fluctuation of the river water level can be weakened, and the vibration of the floating ball 21 is weakened.
Further, a plurality of laser lamps 11 in the sand content photoelectric quantization device 1 of this embodiment are sequentially arranged from top to bottom, the laser lamp placing barrel 16 is vertically placed, a plurality of laser holes are sequentially formed in the laser lamp placing barrel 16 from top to bottom, and the plurality of laser lamps 11 are correspondingly arranged in the plurality of laser holes one by one. The plurality of photoelectric plates 12 are arranged opposite to the plurality of laser lamps 11 in a one-to-one correspondence, and laser light emitted from the laser lamps 11 can irradiate the photoelectric plates 12 in a one-to-one correspondence. When the laser emitted by the laser lamp 11 irradiates the photoelectric plate 12 through the measured water body, the photoelectric plate 12 absorbs the corresponding light and generates current, the ammeter 13 displays the current generated by the corresponding photoelectric plate 12, under the condition that the light intensity is equal, when the light passes through the water body with different sand contents, the lost light energy is different, namely, the change of the sand content along the vertical line can lead the light transmittance of the sand-containing water body to be different along the vertical line, so that the readings generated by the ampere meters 13 are different, and the sand content which is difficult to measure can be converted into an electric signal which is easy to measure and is output.
Notably, the lower parts of the photoelectric board mounting cylinder 15 and the laser lamp mounting cylinder 16 of the present embodiment are fixedly connected by a link.
Further, the recording circuit 17 includes a first power source 171, a first switch 172 and a video recorder 173, the first power source 171, the first switch 172 and the video recorder 173 are connected in series, and the video recorder 173 faces to the plurality of ampere meters 13; a number of parallel laser lights 11 are also connected in parallel with the recorder 173. The photoelectric characteristics of the laser lamps 11 are the same and the laser lamps 11 are required to be independently connected with a power supply in parallel so as to ensure that the light intensity emitted by each laser lamp 11 is equal. The video recorder 173 is connected in parallel with the laser light 11 in an electrical circuit. When the sand content is converted into an electrical signal output from the ammeter 13, the recorder 173 can record readings of each ammeter 13 in real time synchronously, so that the vertical distribution of the sand content can be converted from the readings of the ammeter 13 at a later stage. It should be noted that the numbers of the plurality of ammeter 13 are in one-to-one correspondence with the vertical positions of the photoelectric plates 12, so that when reading the ammeter 13, the vertical positions of the photoelectric plates 12, i.e. the vertical positions of the corresponding sand content measuring points, are also known. After the readings of each ammeter 13 are recorded, the relation between the sand content and the readings of the ammeter 13 of the device is determined by using the existing sand content measuring instrument or method, and then the recorded readings of the ammeter 13 can be converted into the sand content according to the determined relation, so that the vertical line distribution condition of the sand content is obtained.
Further, the light shielding sleeve 14 is slidably sleeved outside the laser lamp 11, and in use, the bottom end of the light shielding sleeve 14 needs to be arranged at a position just contacting the water surface, so as to define the upper limit of the vertical position of the sand content measurement. That is, the shading sleeve 14 can shade all the laser light above the water surface, the photoelectric plate 12 above the water surface does not generate current, and the corresponding reading of the ammeter 13 is zero, so that the ammeter 13 above the water surface and the ammeter below the water surface can be distinguished from each other. The lower limit of the vertical position of the sand content measurement, namely the surface of the river bed, is not limited by a member. The light emitted by the laser lamp 11 buried in the sand bed cannot irradiate the photoelectric plate 12 due to the barrier of the sand, so that the loop is free of current, and the ammeter 13 reads zero.
The foregoing is merely illustrative of the preferred embodiments of the present invention and is not intended to limit the embodiments and scope of the present invention, and it should be appreciated by those skilled in the art that equivalent substitutions and obvious variations may be made using the teachings of the present invention, which are intended to be included within the scope of the present invention.
