Description

Technical Field

[0001] The utility model belongs to the technical field of transparency disks, in particular to a novel seawater transparency disk. Background Art

[0002] Water transparency is a commonly used indicator of water quality. The presence of suspended matter and colloids in water reduces transparency. Transparency is the opposite of turbidity: the more suspended matter in the water, the lower its transparency. Measuring seawater transparency is often necessary in marine ecological monitoring. Existing methods for measuring water transparency use a Secchi disc. A Secchi disc consists of a black and white area on its surface and a weight at its bottom. Visibility varies at different depths. When the black and white areas on the disc's surface become indistinguishable to the naked eye, the corresponding depth serves as an indicator of water turbidity. The clearer the water, the deeper the disc's visibility. Existing Secchi discs are susceptible to seawater surges, wind and waves, and temperature fluctuations during use, making them prone to breakage, impacting their usability. Furthermore, Secchi discs often consist of a single disc, weight, and measuring rope. Once the disc is damaged, it must be completely replaced, resulting in a high wear rate. Utility Model Content

[0003] Based on the above background, the purpose of the present invention is to provide a new type of seawater transparency disc, which can reinforce the transparency disc and effectively reduce the chance of the disc body breaking. The disc body and the plumb bob are detachably connected, and parts can be replaced to reduce the overall loss rate of the transparency disc.

[0004] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0005] A novel seawater transparency disc comprises a transparency disc, a weight, and a connecting block. The transparency disc is penetrated by a mounting hole, the weight is located below the mounting hole, and the connecting block is located above the mounting hole. The weight and connecting block are snap-connected within the mounting hole. A measuring rope is provided on the top of the connecting block, and a rope winding box is provided at the end of the measuring rope away from the connecting block for winding the measuring rope.

[0006] The outer side of the transparency disk is covered with a first silicone sleeve, and the side surface of the mounting hole is covered with a second silicone sleeve.

[0007] Preferably, a connecting rod is fixed on the top of the weight, and a clamping groove is opened on the side of the connecting rod;

[0008] The bottom of the connecting block is provided with a connecting groove, and the connecting rod is plugged into the connecting groove; the side of the connecting groove is provided with a sliding groove, and a sleeve is provided in the connecting block, one end of the sleeve is connected to the sliding groove, and the other end is connected to the side of the connecting block;

[0009] A snap-fit block is provided in the sliding groove for sliding engagement, and the snap-fit block is engaged with the snap-fit groove. A sliding rod is provided on the side of the snap-fit block away from the connecting groove, and the other end of the sliding rod is slidably provided in the sleeve. One end of the sliding rod is fixedly connected to a pull rod, and by pulling the pull rod, the sliding rod and the snap-fit block can be driven to slide in the sliding groove; a spring is provided on the side of the sliding rod, and the two ends of the spring are respectively fixedly connected to the sliding groove and the snap-fit block.

[0010] Preferably, the upper and lower ends of the first silicone sleeve cover the upper and lower ends of the outer side of the transparency disk, and the upper and lower ends of the second silicone sleeve cover the upper and lower ends of the transparency disk around the mounting hole, which can better reinforce the transparency disk.

[0011] Preferably, the measuring rope is divided into multiple sections at equal intervals, and different sections are marked with different colors. There is no need to measure the entire measuring rope. It is only necessary to measure the section of the measuring rope closest to the water surface and the color number of the measuring rope submerged in the water to obtain the transparency depth of the sea water.

[0012] Preferably, a sealing plug is fixed on the pull rod, and the sealing plug is slidably connected to the inner wall of the sleeve. When measuring, the sealing plug prevents seawater from flowing into the sleeve and causing corrosion to the connecting rod and the connecting groove, and the pressure of the seawater can exert thrust on the sealing plug, thereby better pushing the clamping block to fix the clamping groove.

[0013] Preferably, a pull ring is provided at one end of the pull rod extending out of the connecting block, and pulling the pull ring can better facilitate the disassembly of the heavy hammer and the connecting block.

[0014] Preferably, the clamping block includes a mounting plate and a plurality of triangular blocks, the triangular blocks are evenly and equidistantly arranged on the side of the mounting plate, the triangular blocks are engaged with the clamping grooves, and the arrangement of the plurality of triangular blocks improves the fixed connection between the weight and the connecting block.

[0015] Preferably, the snap-in grooves are symmetrically opened on the left and right sides of the connecting rod. The snap-in grooves are symmetrically opened on the left and right sides, so that the snap-in force on both sides of the connecting rod is uniform, avoiding the snap-in force on one side, which causes the device to be subjected to different buoyancy in seawater and causes the transparency disk to tilt, affecting the measurement results.

[0016] Preferably, positioning holes are symmetrically provided on the top of the weight, a positioning seat is fixed on the side of the connecting block, and positioning rods are symmetrically provided on the bottom of the positioning seat. Through holes corresponding to the positioning holes are penetrated on the second silicone sleeve and the transparency disk, and the positioning rods are plugged into the positioning holes. The plugging of the positioning rods into the positioning holes can prevent the weight from rotating relative to the transparency disk in the mounting hole after being connected to the connecting block, thereby improving the stability of the weight and the transparency disk.

[0017] Preferably, the transparency disk is made of aluminum-plastic plate, with the upper layer being a white plastic plate and the lower layer being an aluminum plate, which has the advantages of strong impact resistance and high toughness.

[0018] The utility model has the following beneficial effects:

[0019] 1. The utility model uses the first silicone sleeve to be sleeved from the side of the transparency disk, which can effectively buffer the collision impact between the transparency disk and the hull, and also reinforce the transparency disk, which can prevent the transparency disk from being broken by seawater and causing cracks due to seawater temperature differences and other reasons, thereby extending the service life and use effect of the transparency disk. The second silicone sleeve reinforces the transparency disk from the middle of the transparency disk and can seal the connection between the connecting block and the heavy hammer.

[0020] 2. The utility model completes the clamping and fixing of the weight and the connecting block through the cooperation of the clamping block and the clamping groove. When it is necessary to replace weights of different weights or transparency disks of different diameters, the pull rod is pulled to drive the sliding rod to slide in the sleeve and the sliding groove, driving the connecting block to slide into the sliding groove and disengage from the clamping groove. The connecting block and the weight are separated to replace the corresponding parts, which effectively reduces the loss rate of the transparency disk and the weight, reduces the cost of use, and is more practical.

[0045] Preferably, a sealing plug 38 is fixed on the pull rod 36, and the sealing plug 38 is slidably connected to the inner wall of the sleeve 33. When measuring, the sealing plug 38 prevents seawater from flowing into the sleeve 33 and causing corrosion to the connecting rod 21 and the connecting groove 31, and the pressure of the seawater can apply thrust to the sealing plug 38, thereby better pushing the clamping block 34 to fix the clamping groove 22.

[0046] Preferably, a pull ring 39 is provided at one end of the pull rod 36 extending out of the connecting block 3 , and pulling the pull ring 39 can facilitate the disassembly of the heavy hammer 2 and the connecting block 3 .

[0048] Preferably, the snap-in grooves 22 are symmetrically opened on the left and right sides of the connecting rod 21. The snap-in grooves 22 are symmetrically opened on the left and right sides, so that the snap-in receiving force on both sides of the connecting rod 21 is uniform, avoiding the snap-in receiving force on one side, which causes the device to be subjected to different buoyancy in seawater and causes the transparency disk 1 to tilt, affecting the measurement results.

[0049] Preferably, positioning holes 23 are symmetrically provided on the top of the weight 2, a positioning seat 310 is fixed on the side of the connecting block 3, and a positioning rod 311 is symmetrically provided on the bottom of the positioning seat 310.

[0050] Preferably, the transparency disk 1 is made of aluminum-plastic plate, wherein the upper layer is white plastic plate and the lower layer is aluminum plate, which has the advantages of strong impact resistance and high toughness.

[0051] The working principle of the present invention is as follows: select a suitable transparency disk 1, a heavy hammer 2 and a connecting block 3, insert the connecting rod 21 at the top of the heavy hammer 2 into the connecting groove 31 at the bottom of the connecting block 3, and the clamping block 34 is clamped in the clamping groove 22 under the elastic force of the spring 37 to complete the fixation of the connecting block 3, and the sealing plug 38 prevents seawater from flowing into the sleeve 33 to corrode the connecting rod 21 and the connecting groove 31, and the pressure of the seawater can apply a thrust to the sealing plug 38, so as to better push the clamping block 34 to fix the clamping groove 22, and prevent the heavy hammer from being inserted into the positioning hole 23 through the matching connection of the positioning rod 311. After being connected to the connecting block 3, the weight 2 rotates relative to the transparency disk 1 in the mounting hole 11, improving the stability of the weight 2 and the transparency disk 1. The first silicone sleeve 12 is inserted from the side of the transparency disk 1 to effectively cushion the impact of the transparency disk 1 and the hull. It also reinforces the transparency disk 1, preventing the transparency disk 1 from being broken by seawater due to temperature differences and other reasons, thereby extending the service life and performance of the transparency disk 1. The second silicone sleeve 13 reinforces the transparency disk 1 from the middle and seals the connection between the connecting block 3 and the weight 2. The transparency disk 1 is placed in the seawater for measurement. By measuring the nearest section of the measuring rope 4 on the water surface and the number of colors of the measuring rope 4 submerged in the water, the transparency depth of the seawater can be obtained. When the weight 2 or the transparent disk 1 needs to be replaced, pull the pull ring 39 to drive the pull rod 36, the sliding rod 35, and the clamping block 34 to slide, so that the clamping block 34 is out of contact with the clamping groove 22. After the connecting block 3 and the weight 2 are separated and the corresponding parts are replaced, the disassembly is convenient, the practicality is high and the cost is saved.
