Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, and in particular to a wireless water quality monitoring device. Background Technology

[0002] Wireless water quality monitoring equipment is an intelligent device that uses wireless communication technology to collect, transmit, and analyze water quality data in real time. It consists of sensors, a wireless transmission module, and a data processing system, and can remotely monitor multiple key indicators in water bodies (such as pH value, dissolved oxygen (DO), turbidity, temperature, heavy metal content, etc.), and is therefore widely used in environmental protection, water affairs, agriculture, industry, and other fields.

[0003] Although the application of wireless water quality monitoring equipment has greatly improved monitoring efficiency, there are still obvious drawbacks: most wireless water quality monitoring equipment on the market is easily affected by water flow and has insufficient floating stability, which in turn affects the accuracy of monitoring data. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a wireless water quality monitoring device that can improve the accuracy of monitoring data.

[0005] The objective of this utility model is achieved by the following technical solution: a wireless water quality monitoring device, comprising: a shell, a float assembly, and a counterweight;

[0006] The housing is used to install a water quality testing instrument;

[0007] The float assembly is movably connected to the housing so that it can be raised and lowered relative to the float assembly;

[0008] The counterweight is movably connected to the housing and the float assembly so as to be able to rise and fall relative to the housing and the float assembly. The counterweight presses against the float assembly, the housing is supported by the float assembly, and the float assembly has a limiting part that prevents the housing from floating upward.

[0009] Furthermore, the cross-sectional area of ​​the counterweight gradually increases along the direction of gravity.

[0010] Furthermore, the housing has a guide cylinder with a vertical guide hole, the counterweight is connected to a guide rod, the top of the guide rod is provided with a pressing block, and the guide rod is movably inserted into the vertical guide hole; the float assembly has a clamping part, which is located between the pressing block and the guide cylinder.

[0011] Furthermore, the float assembly includes an upper float and a lower float that are separated from each other. The limiting part is provided on the upper float, and the upper float is movably connected to the housing so as to be able to rise and fall relative to the float assembly. The lower float is connected to the housing and supports the housing.

[0012] Furthermore, the housing is provided with a vertical guide groove, and the limiting part is connected to a guide block, which is movably engaged with the vertical guide groove.

[0013] Furthermore, a buffer layer is provided at the bottom of the vertical guide groove, and the buffer layer is spaced apart from the guide block. The buffer layer is used to elastically abut against the guide block.

[0014] Furthermore, multiple vertical guide grooves are provided, and the multiple vertical guide grooves are distributed circumferentially around the housing; multiple guide blocks are provided, and the multiple guide blocks are respectively movably engaged with one of the vertical guide grooves.

[0015] Furthermore, the float assembly also includes a vertical linkage extension rod, through which the upper float is connected to the limiting part, and the vertical linkage extension rod is movably inserted through the top through hole of the housing.

[0016] Furthermore, the vertical linkage extension rod is provided in multiple parts, which are distributed at intervals along the horizontal direction, and each of the vertical linkage extension rods is inserted into one of the top through holes of the housing.

[0017] Furthermore, the housing is equipped with a photovoltaic panel, a water quality analyzer, and a photovoltaic cell, with the photovoltaic panel and the water quality analyzer being electrically connected to the photovoltaic cell.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. Based on the fact that the float assembly is movably connected to the housing so as to be able to rise and fall relative to the float assembly; it can be understood that for general water quality monitoring equipment, the float and the housing will float and sink together when impacted by water flow. However, this utility model is different from general water quality monitoring equipment. The phrase "the float assembly is movably connected to the housing so as to be able to rise and fall relative to the float assembly" does not mean that the float assembly drives the housing to move, but rather that the rising and falling movement of the float assembly suppresses the movement of the housing. In other words, when the wireless water quality monitoring equipment is impacted, the float assembly can preferentially withstand the impact, and the float assembly dissipates the impact force through its own rising and falling movement, achieving the effect of keeping the housing stable. It should be noted that, see Figure 1The upper float in the middle is only a part of the float assembly that is connected to the shell to produce the technical effect of suppressing the lifting and lowering movement of the shell, rather than all components of the float assembly producing this suppressing effect.

[0020] 2. The counterweight is movably connected to the housing and the float assembly, allowing for lifting and lowering relative to the housing and the float assembly. The counterweight presses against the float assembly. It can be understood that the counterweight serves two purposes: first, when the wireless water quality monitoring device is placed in a water area, the counterweight provides basic stability to the housing and the float assembly in the vertical direction; second, it provides the same restraining effect as the float assembly on the housing, due to F... 浮 =G 浮 The float assembly is typically lightweight, so if the water flow impact is significant, the float assembly cannot completely counteract the impact, and the housing can still move up and down. With the addition of a counterweight, due to the counterweight's weight, F... 浮 =G 浮 +F 配重块下压力 The movements of the counterweight and the float assembly are coupled. When the counterweight rises, it reduces the downward force of the system, disrupting the original balance and allowing buoyancy to dominate the movement of the float assembly. Conversely, if the counterweight remains stationary, the float assembly cannot overcome its downward force independently. In other words, the float assembly can only rise after the counterweight rises, thus increasing the threshold for resisting the impact force of the water flow.

[0021] 3. Based on the fact that the housing is supported by the float assembly, the float assembly has a limiting part that prevents the housing from floating upward. It can be understood that the connection between some components of the float assembly and the housing has the effect of suppressing the lifting and lowering movement of the housing. Here, it is clearly stated that this component is a limiting part. The float assembly also has other components that can support the housing. Attached Figure Description

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] like Figures 1 to 3 As shown, a preferred embodiment of this utility model discloses a wireless water quality monitoring device, including: a housing 1, a float assembly 2, and a counterweight 3;

[0035] The housing 1 is used to install the water quality analyzer 9;

[0036] The float assembly 2 is movably connected to the housing 1 so that it can be raised and lowered relative to the float assembly 2;

[0037] The counterweight 3 is movably connected to the housing 1 and the float assembly 2 so that it can be raised and lowered relative to the housing 1 and the float assembly 2. The counterweight 3 presses on the float assembly 2, and the housing 1 is supported by the float assembly 2. The float assembly 2 has a limiting part 21 that prevents the housing 1 from floating upward.

[0038] Based on the fact that the housing 1 is used to install the water quality analyzer 9, it can be understood that the housing 1 has a receiving space, and the water quality analyzer 9 or its constituent modules (such as sensor modules, such as microprocessors) are all disposed within the receiving space of the housing 1. It should be noted that the objective of this utility model is to improve the accuracy of monitoring data by enhancing the floating stability of the housing 1; therefore, it is necessary to clearly define that the water quality analyzer 9 is installed in the housing 1.

[0039] Based on the fact that the float assembly 2 is movably connected to the housing 1, allowing it to rise and fall relative to the float assembly 2; it can be understood that for general water quality monitoring equipment, the float and the housing will float and sink together when impacted by water flow. However, this utility model differs from general water quality monitoring equipment. The phrase "the float assembly 2 is movably connected to the housing 1, allowing it to rise and fall relative to the float assembly 2" does not mean that the float assembly 2 drives the housing 1 to move, but rather that the rising and falling movement of the float assembly 2 suppresses the movement of the housing 1. In other words, when the wireless water quality monitoring equipment is impacted, the float assembly 2 can preferentially withstand the impact, and the float assembly 2 dissipates the impact force through its own rising and falling movement, achieving the effect of keeping the housing 1 stable. It should be noted that, see Figure 1 The upper float 23 is only a part of the float assembly 2 that is connected to the housing 1 to produce the technical effect of suppressing the lifting and lowering movement of the housing 1, rather than all components of the float assembly 2 producing this suppression effect.

[0040] The counterweight 3 is movably connected to the housing 1 and the float assembly 2, allowing it to rise and fall relative to the housing 1 and the float assembly 2. The counterweight 3 presses against the float assembly 2. It can be understood that the counterweight 3 serves two purposes: first, when the wireless water quality monitoring device is placed in a water area, the counterweight 3 provides basic stability to the housing 1 and the float assembly 2 in the vertical direction; second, it provides the same restraining effect as the float assembly 2 on the housing 1, due to F... 浮 =G 浮The float assembly 2 is typically lightweight, so if the water flow impact is significant, the float assembly 2 cannot completely counteract the water flow impact, and the housing 1 can still move up and down. After adding the counterweight 3, due to the weight of the counterweight, F... 浮 =G 浮 +F 配重块下压力 The movements of counterweight 3 and float assembly 2 are coupled. When counterweight 3 rises, it reduces the downward force of the system, disrupting the original balance and allowing buoyancy to dominate the movement of float assembly 2. Conversely, if counterweight 3 remains stationary, float assembly 2 cannot overcome its downward force independently. In other words, float assembly 2 can only rise after counterweight 3 rises, thus increasing the threshold for resisting the impact force of water flow.

[0041] Since the housing 1 is supported by the float assembly 2, the float assembly 2 has a limiting part 21 that prevents the housing 1 from floating upward. It can be understood that the connection between some components of the float assembly 2 and the housing 1 has the effect of suppressing the lifting and lowering movement of the housing 1. Here, it is clearly stated that this component is the limiting part 21. The float assembly 2 also has other components that can support the housing 1.

[0042] In summary, the working principle of this utility model is as follows: When the wireless water quality monitoring device is subjected to external impact, its rising sequence is: counterweight 3 → float assembly 2 → housing 1. The counterweight 3 responds first by rising to offset part of the impact force, and then drives the float assembly 2 to rise through the limiting part 21. When the impact force below causes the float to rise rapidly, the volume of liquid displaced by the float increases instantaneously (Archimedes' principle), and the buoyancy F = ρgV increases sharply, forming a resistance in the opposite direction to the impact force. Theoretically, this can completely offset the impact force. Since the float assembly 2 does not drive the housing 1 to rise or fall when it moves up and down, the housing 1 can always remain stable, ensuring the accuracy of the monitoring data of the water quality analyzer 9 installed in the housing 1.

[0043] like Figure 3 As shown, the cross-sectional area of ​​the counterweight 3 gradually increases along the direction of gravity. It can be understood that the large area at the bottom of the counterweight 3 results in greater resistance; when water flow or external forces act, the wide bottom structure can withstand a greater impact force from the water flow, thus preventing a significant drop and maintaining a stable state.

[0044] like Figures 3 to 6As shown, preferably, the housing 1 has a guide cylinder 4 with a vertical guide hole 41. The counterweight 3 is connected to a guide rod 5, and a pressing block 51 is provided at the top of the guide rod 5. The guide rod 5 is movably inserted into the vertical guide hole 41. The float assembly 2 has a clamping part 22, which is located between the pressing block 51 and the guide cylinder 4. It can be understood that the counterweight 3 is connected to the housing 1 through the guide rod 5, and the counterweight 3 can drive the clamping part 22 to move up and down through the guide rod 5.

[0045] like Figure 3 As shown, preferably, the float assembly 2 includes a separate upper float 23 and a lower float 24. The limiting part 21 is disposed on the upper float 23, and the upper float 23 is movably connected to the housing 1 so as to be able to rise and fall relative to the float assembly 2. The lower float 24 is connected to the housing 1 and supports the housing 1. It can be understood that the float assembly 2 is a split float, and the limiting part 21 and the clamped part 22 are connecting parts. Each float has a different function. The upper float 23 is used to perform rising and falling movements to offset external impacts, and the lower float 24 is used to support the housing 1. It should be noted that an inner groove is formed in the lower float 24 to accommodate the housing 1 and achieve the supporting effect.

[0046] like Figure 4 As shown, preferably, the housing 1 has a vertical guide groove 6, and the limiting part 21 is connected to a guide block 221, the guide block 221 being movably engaged with the vertical guide groove 6. It can be understood that the limiting part 21 is located inside the housing 1, and the guide block 221 can move up and down within the vertical guide groove 6.

[0047] like Figures 4 to 5 As shown, preferably, a buffer layer 61 is provided at the bottom of the vertical guide groove 6. The buffer layer 61 is spaced apart from the guide block 221, and the buffer layer 61 is used to elastically abut against the guide block 221. It can be understood that the buffer layer 61 is made of a weather-resistant material (e.g., silicone rubber). When the guide block 221 moves downward, the buffer layer 61 elastically abuts against the guide block 221, which on the one hand can prevent the guide block 221 from sliding out of the vertical guide groove 6, and on the other hand can quickly stabilize the float assembly 2.

[0048] like Figures 4 to 5As shown, preferably, multiple vertical guide grooves 6 are provided, and the multiple vertical guide grooves 6 are distributed circumferentially around the housing 1 at intervals; multiple guide blocks 221 are provided, and the multiple guide blocks 221 are respectively movably engaged with one of the vertical guide grooves 6. It can be understood that providing multiple vertical guide grooves 6 and multiple guide blocks 221 is beneficial for even load distribution, avoiding stress concentration, and extending the service life of the float assembly 2.

[0049] like Figures 5 to 6 As shown, preferably, the float assembly 2 further includes a vertical linkage extension rod 7, through which the upper float 23 is connected to the limiting part 21. The vertical linkage extension rod 7 is movably inserted through the top through hole 11 of the housing 1. It can be understood that the vertical linkage extension rod 7 is used to connect the limiting part 21 and the clamped part 22, thereby realizing the linkage connection of the float assembly 2.

[0050] like Figures 5 to 6 As shown, preferably, multiple vertical linkage extension rods 7 are provided, and the multiple vertical linkage extension rods 7 are distributed at intervals along the horizontal direction. Each vertical linkage extension rod 7 is inserted into one of the top through holes 11 of the housing 1. It can be understood that providing multiple vertical linkage extension rods 7 is beneficial for even load distribution, avoiding stress concentration, and extending the service life of the float assembly 2.

[0051] like Figures 5 to 8 As shown, preferably, the housing 1 is equipped with a photovoltaic panel 8, a water quality analyzer 9, and a photovoltaic cell 10. The photovoltaic panel 8 and the water quality analyzer 9 are electrically connected to the photovoltaic cell 10. It can be understood that the photovoltaic panel 8 absorbs light energy and converts it into electrical energy, which is stored in the photovoltaic cell 10. The photovoltaic cell 10 serves as a power source for the water quality analyzer 9, improving its operating endurance. Furthermore, the bottom of the housing 1 is provided with a water inlet and a water outlet, both of which are connected to the water quality analyzer 9 via pipes. The water sample to be tested enters the water quality analyzer 9 through the water inlet and is discharged through the water outlet after testing.

[0052] The working principle of this utility model is as follows: When the wireless water quality monitoring device is subjected to external impact, its rising sequence is: counterweight 3 → float assembly 2 → housing 1. When the counterweight 3 is impacted by the upward water flow, the counterweight 3 rises, driving the guide rod 5 to rise. Since the limiting part 21 in the float assembly 2 is connected to the guide rod 5, the guide rod 5 further drives the limiting part 21 and the upper float 23 to rise. The rise of the counterweight 3 first offsets part of the impact force. When the upper float 23 rises rapidly, the volume of liquid displaced by the upper float 23 increases instantaneously, and the buoyancy increases sharply, forming a resistance in the opposite direction to the impact force, which theoretically can completely offset the impact force. At the same time, the clamped part 22 slides in the vertical guide groove 6 and does not drive the housing 1 to rise. Therefore, the cooperation between the counterweight 3 and the float assembly 2 can suppress the up-and-down floating of the housing 1 and improve the floating stability of the housing 1. By improving the floating stability of the shell 1, the accuracy of the raw data monitored by the water quality analyzer 9 is ensured. The microprocessor embedded in the water quality analyzer 9 calibrates, compensates (such as temperature compensation), and filters the various raw data received, converting them into digital signals and uploading them to the cloud platform or server wirelessly (e.g., LoRa, NB-IoT, 4G / 5G).
