Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, and in particular to a water quality monitor that is resistant to being blocked by weeds. Background Technology

[0002] Water quality monitoring instruments are primarily used in the water quality monitoring market, and therefore are mainly influenced by the development of that market. Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants, and their changing trends to evaluate water quality. The main monitoring items can be divided into two categories: one category consists of comprehensive indicators reflecting water quality, such as temperature, color, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand (COD), and biochemical oxygen demand (BOD); the other category includes toxic substances such as phenols, cyanides, arsenic, lead, chromium, cadmium, mercury, and organochlorine pesticides.

[0003] A search revealed that Chinese patent number CN222926722U discloses a water quality monitor that is waterproof and can be blocked by weeds, including a float assembly and a float fixing rope. The top of the float assembly is threadedly connected to a fixing bracket, and an electrical control box assembly is fixedly installed on the top of the fixing bracket. A solar panel is movably installed on the front end of the electrical control box assembly. The float fixing rope is fixedly installed on the outer surface of the float assembly, and an isolation float ring assembly is floatingly connected around the float assembly.

[0004] To avoid obstructing the monitoring probe by aquatic plants during water quality monitoring and affecting the monitoring effect, the aforementioned public documents adopted components such as floating body components, isolation floating body ring components, underwater isolation nets, and sinking block rings to protect the monitoring probe and isolate it from the aquatic plants. However, some problems exist in actual use. The underwater isolation net isolates the entire structure from top to bottom. When monitoring deep water quality, firstly, the amount of underwater isolation net used is large, and its volume is also larger. Consequently, it is more affected by water currents. When the underwater isolation net is disturbed too much, it will push the monitoring probe to move, which will affect the accuracy of the detection data of the monitoring probe.

[0005] To address the aforementioned problems, this application proposes a water quality monitor that is protected from being obscured by waterproof grass. Utility Model Content

[0006] This invention provides a water quality monitor that is waterproof and can be blocked by weeds, in order to solve the above-mentioned technical problems.

[0007] To solve the above-mentioned technical problems, this utility model provides a water quality monitor that is waterproof and protected from weeds, including a floating island. A monitoring device and a cable box are fixedly installed on the top of the floating island. The monitoring device is electrically connected to a cable, and a monitoring probe is fixedly connected to the end of the cable.

[0008] An isolation mechanism is installed below the floating island, and the monitoring probe is located inside the isolation mechanism. The isolation mechanism is used to prevent aquatic plants from obstructing the monitoring probe.

[0009] A cable retraction mechanism is fixedly installed on one side of the cable box. The cable retraction mechanism is used for cable retraction and extension operations.

[0010] Preferably, the isolation mechanism includes a cylindrical mesh cage, the monitoring probe is located inside the cylindrical mesh cage, a fixing block is connected through the top of the cylindrical mesh cage, the fixing block is sleeved on the outer end of the cable, and the cable is fixedly connected to the cylindrical mesh cage through the fixing block.

[0011] Preferably, a conical counterweight is fixedly connected to the bottom of the cylindrical wire mesh cage.

[0012] Preferably, the cable box has a through hole on one side and a drainage hole at the bottom of the other side.

[0013] Preferably, the take-up and take-down mechanism includes two mounting plates, which are fixedly connected to one side of the cable box. Two friction wheels distributed vertically are movably connected between the two mounting plates. A motor is fixedly connected to the outer side of one of the mounting plates. The output shaft of the motor is fixedly connected to the end of one of the friction wheels. The cable passes between the two friction wheels and passes through a through hole.

[0014] Preferably, a through hole is provided at the center of the top of the floating island, through which the cable passes.

[0015] Compared with related technologies, the water quality monitor that is waterproof and can be blocked by weeds provided by this utility model has the following advantages:

[0016] Water quality can be monitored by combining monitoring equipment, cables, and monitoring probes. The combination of cylindrical net cages and conical counterweights in the isolation mechanism, along with the use of cables for traction, allows the monitoring probes to be smaller when submerged in water, and they are less affected by water flow disturbances, thereby improving the accuracy of water quality monitoring data.

[0023] Please see Figure 1-5 The technical solution provided by this utility model specifically includes the following embodiments:

[0024] A water quality monitor that is waterproof and can be covered by grass includes a floating island 1. A monitoring device 2 and a cable box 8 are fixedly installed on the top of the floating island 1. The monitoring device 2 is electrically connected to a cable 3, and a monitoring probe 4 is fixedly connected to the end of the cable 3.

[0025] The monitoring device 2 is equipped with a heightening block at the bottom to prevent water splashed onto the floating island 1 from directly contacting the monitoring device 2 and causing damage.

[0026] An isolation mechanism is installed below the floating island 1, and the monitoring probe 4 is located inside the isolation mechanism. The isolation mechanism is used to prevent aquatic plants from obstructing the monitoring probe 4.

[0027] The cable box 8 is fixedly installed with a cable retraction mechanism 9, which is used to retract and extend the cable 3.

[0028] The isolation mechanism includes a cylindrical mesh cage 5, the monitoring probe 4 is located inside the cylindrical mesh cage 5, a fixing block 6 is connected through the top of the cylindrical mesh cage 5, the fixing block 6 is sleeved on the outer end of the cable 3, the cable 3 is fixedly connected to the cylindrical mesh cage 5 through the fixing block 6, and a conical counterweight block 7 is fixedly connected to the bottom of the cylindrical mesh cage 5.

[0029] The cylindrical net cage 5 can protect the monitoring probe 4 inside so that it is not blocked by aquatic plants. The cable 3 is fixedly connected to the cylindrical net cage 5 through the fixing block 6. During this process, in addition to connecting the monitoring equipment 2 and the monitoring probe 4, the cable 3 can also act as a traction rope to pull the cylindrical net cage 5. The shape of the conical counterweight block 7 makes it easier for the cylindrical net cage 5 to pass through aquatic plants when it is submerged, and it is not easily affected. At the same time, it can also add weight to the cylindrical net cage 5 to make it more stable when it is submerged and reduce the disturbance of water flow.

[0030] The cable box 8 has a through hole 81 on one side and a drainage hole 82 at the bottom of the other side.

[0031] The cable box 8 can be used to coil the cable 3. When the cable 3 is extended by the winding mechanism 9, the cable 3 coiled in the cable box 8 will pass through the through hole 81. Conversely, when the cable 3 is retrieved, the cable 3 will also pass through 81 and be coiled randomly in the cable box 8. The randomly coiled cable 3 does not affect the subsequent extension. The retrieved cable 3 is attached with water. After entering the inside of the cable box 8, the water accumulates and can finally be discharged through the drain hole 82 to prevent the water in the cable box 8 from accumulating more and more.

[0032] The take-up and take-down mechanism 9 includes two mounting plates 91, which are fixedly connected to one side of the cable box 8. Two friction wheels 92, which are distributed vertically, are movably connected between the two mounting plates 91. A motor 93 is fixedly connected to the outside of one of the mounting plates 91. The output shaft of the motor 93 is fixedly connected to the end of one of the friction wheels 92. The cable 3 passes between the two friction wheels 92 and passes through the through hole 81.

[0033] One of the friction wheels 92 is driven to rotate by the motor 93. Since the two friction wheels 92 clamp the cable 3, the other friction wheel 92 will also rotate to transport the cable 3. The outer end of the friction wheel 92 is provided with an annular recess that matches the cable 3, which can prevent the cable 3 from falling off the friction wheel 92.

[0034] A through hole 11 is provided at the center of the top of the floating island 1, through which the cable 3 passes. The through hole 11 is located at the center of the floating island 1, so that when the cable 3 passes through the through hole 11, the overall center of gravity is more centered and the stability is better.

[0035] Working principle:

[0036] The two ends of the cable 3 are connected to the monitoring device 2 and the monitoring probe 4, respectively. The cable 3 is coiled inside the cable box 8. During the monitoring operation, the floating island 1 floats on the water surface. The motor 93 in the retrieval mechanism 9 drives a friction wheel 92 to rotate, and then cooperates with another friction wheel 92 to clamp and transport the cable 3. The cable 3 is gradually pulled out of the cable box 8, while the monitoring probe 4 at the end of the cable 3 follows the cylindrical net cage 5 to dive into the water. When the cylindrical net cage 5 dives, the conical counterweight 7 can break the water plants so that it can dive into the water smoothly. The cylindrical net cage 5 can also separate the water plants so that the monitoring probe 4 is not blocked by the water plants. After the monitoring is completed, the retrieval mechanism 9 transports the cable 3 in the opposite direction to the cable box 8 for coiling. During this period, the cylindrical net cage 5 will be gradually pulled upward by the cable 3.
