DETAILED DESCRIPTION

[0029] The present invention is further described below in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0030] In the description of the present utility model, it should be noted that for directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicating directions and positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and cannot be understood as limiting the specific protection scope of the present utility model.

[0031] See also Figure 1 and 2 , which are the stereogram and exploded diagram of the water quality detection probe provided in this embodiment. The water quality detection probe includes a probe body 1, a protective cover 2 and an ultraviolet lamp 3, and may also include a controller (not shown).

[0032] Please combine Figure 3 The probe body 1 includes a detection part 11, which is arranged at one end of the probe body 1 and is used to detect water quality parameters in the water body.

[0033] See also Figure 4 , a cavity 21 is provided on the protective cover 2, and the detection part 11 is inserted into the cavity 21. A plurality of through holes 22 are also provided on the protective cover 2, and each through hole 22 is connected to the cavity 21 respectively. The through hole 22 is located in the area between the detection part 11 and the ultraviolet lamp 3. The cavity is used to accommodate the detection part 11, and the detection part 11 is inserted into the cavity 21. When the detection part 11 is detecting, it contacts the water quality with the detection through the through hole 22. In this embodiment, by covering the outer side of the detection part 11 with the protective cover 2, the detection part 11 can be protected to avoid the problem that impurities in the water body are deposited on the detection part 11 and promote the growth of algae and fungi on the detection part 11. Thereby, the stability and accuracy of the detection data of the probe body 1 are improved.

[0034] By providing a plurality of through holes 22, each through hole 22 can allow water to flow through, so that a closed water flow environment is not formed in the protective cover 2, thereby improving the accuracy of its detection. At the same time, the protective cover 2 can also be placed to form a closed water flow environment, which will cause impurities in the water body to block the detection part 11, further improving the accuracy of the detection data of the water quality parameters in the water body by the probe in this embodiment.

[0035] The protective cover 2 can be made of metal or plastic. Its specific shape and size can be adjusted according to the size and shape of the detection part 11 on different probes. In some embodiments, the protective cover 2 can be a hollow structure. The hollow structure prevents a closed water flow environment from being formed between the detection part 11 and the protective cover 2, thereby preventing the detection part 11 from being blocked by the in-service in the water body and affecting its detection results.

[0036] In this embodiment, the protective cover 2 and the probe body 1 can be detachably connected to facilitate replacement and cleaning of the protective cover 2. When too much algae and fungi grow on the protective cover 2, it is sufficient to simply replace the protective cover 2. This can effectively solve the problem of the prior art that the probe body 1 needs to be replaced to detect water quality parameters in the water body, greatly reducing its replacement cost. Figure 5 As shown, it is a schematic diagram of the protective cover 2 and the probe body 1 in a separated state.

[0037] like Figure 5 As shown, the protective cover may include a sleeve 23 and a sleeve 24. The sleeve 23 is mounted on the sleeve body. The sleeve 23 is preferably detachably mounted on the probe body 1. The sleeve 23 can be assembled by two semicircular tubes. When the sleeve 23 needs to be installed, the two semicircular tubes can be wrapped around the outside of the probe body 1. Then the two semicircular tubes can be fixed by screws. That is, the sleeve 23 is installed on the outside of the probe body 1. Sealing cotton can be provided in the sleeve 23, and the sealing cotton can increase the friction between the sleeve 23 and the probe body 1, thereby improving the stability of the sleeve 23 installed on the probe body.

[0038] See also Figure 3, a clamping member 231 may be provided on the sleeve 1 23. A mounting groove 232 and a limiting groove 233 may be provided on the sleeve 1 23, and the mounting groove 232 is connected to the limiting groove 233. A spring 234 is installed in the limiting groove 233, one end of the clamping member 231 is inserted into the limiting groove and connected to the spring 234, and the other end of the clamping member extends out of the mounting groove 232. The clamping member 231 includes a clamping section 235, a connecting section 236 and a limiting section 237. One end of the connecting section 236 is connected to the clamping section 235, and the other end of the connecting section 236 is connected to the limiting section 237. The limiting section 237 is installed in the limiting groove 233 and connected to the spring 234. By providing the limiting section 237, the stability of the entire clamping member 231 during movement can be improved.

[0039] See also Figure 2 and Figure 3 , the second sleeve 24 is clamped on the outside of the first sleeve 23. The second sleeve 24 is installed on the probe body 1 through the first sleeve 23 and wraps the detection part 11 inside. By setting the first sleeve 23 and the second sleeve 24, the second sleeve 24 can be effectively sleeved on the outside of the detection part 11 to protect the detection part 11. The ultraviolet lamp 3 is arranged on the side of the second sleeve 24 away from the first sleeve 23. The ultraviolet lamp 3 can irradiate the detection part 11, thereby preventing algae and fungi from growing on the detection part 11.

[0040] See also Figure 4 , the sleeve 24 may be a T-shaped tube. The sleeve 24 may include a pipe 1 241 and a pipe 2 242. The pipe 1 241 and the pipe 2 242 may be perpendicular to each other, one end of the pipe 1 241 may be snap-connected to the outside of the sleeve 1 23, and the other end is connected to the pipe 2 242. The ultraviolet lamp 3 is installed in the pipe 2 242. By connecting the pipe 1 241 and the pipe 2 242 and installing the ultraviolet lamp 3 in the pipe 2 242 and aligning it with the detection part 11, the pipe 2 242 can not only install and fix the ultraviolet lamp 3, but also ensure that the ultraviolet light of the ultraviolet lamp 3 can be irradiated to the detection part 11 through the connection between the pipe 1 241 and the pipe 2 242, which can effectively inhibit the growth of algae and fungi on the detection part 11, thereby improving the accuracy of water quality detection. The ultraviolet lamp 3 can be installed in the pipe 2 242 by threaded connection.

[0041] See also Figure 6 , 78. A slot 243 matching the clamping member 231 may be provided on the second sleeve 24, and the clamping member 231 is aligned with the slot 243. When the second sleeve 24 needs to be installed, it is only necessary to align the slot 243 of the second sleeve 24 with the clamping member 231 on the first sleeve 23, and then sleeve the second sleeve 24 on the outside of the first sleeve 23, so that the clamping member 231 is inserted into the slot 243 to achieve the installation of the second sleeve 24 on the outside of the first sleeve 23. The entire installation process is simple and convenient, and the fixing effect is good. In this embodiment, when the clamping member 231 is completely received in the installation groove 232, the clamping member 231 and the slot 243 are in a separated state and the spring 234 is in a compressed state. At this time, the clamping member 231 has no limit effect on the second sleeve 24, and the second sleeve 24 can be pulled out from the first sleeve 23. When the clamping member 231 is aligned with the slot 243 , the spring 234 allows the clamping member 231 to extend out of the mounting slot 232 and insert into the slot 243 , thereby allowing the second sleeve 24 to be mounted on the first sleeve 23 through the cooperation between the clamping member 231 and the slot 243 .

[0042] See also Figure 7 and Figure 8 When the clamping section 235 is clamped into the clamping slot 243, the sleeve 24 can be limited and fixed. When the clamping section 235 is away from the clamping slot 243, the sleeve 24 can be pulled out from the sleeve 1 23. The clamping method facilitates the rapid installation and removal of the sleeve 24. In this embodiment, the clamping section 235 can be a trapezoidal structure. And the upper bottom surface of the clamping section 235 of the trapezoidal structure faces the sleeve 24. In the actual clamping process, under the action of the inner wall of the sleeve 24, the clamping section 235 can be pushed to move inward until the clamping section 235 is aligned with the clamping slot 243. At this time, under the elastic force of the spring 234, the clamping section 235 can be directly clamped into the clamping slot 243, so as to fix the sleeve 24.

[0043] Please refer to 7. The ultraviolet lamp 3 can be installed in the cavity 21 or in the side wall of the protective cover 2, as long as the ultraviolet lamp 3 can irradiate ultraviolet light to the detection part 11. By setting the ultraviolet lamp 3 and irradiating the detection part 11 with the ultraviolet lamp 3, the growth of algae and fungi on the detection part 11 can be effectively suppressed under the action of the ultraviolet lamp 3, thereby ensuring the cleanliness of the detection part 11 and ensuring that the detection part 11 can accurately detect the water quality parameters in the water body. In order not to affect the water quality detection, the ultraviolet lamp 3 is preferably used to irradiate ultraviolet light to the detection part 11 when the detection part 11 is in a non-working state.

[0044] In some embodiments, the UV lamp 3 can be a common UV lamp 3 on the market, and its specific model and power can be selected according to the area of ​​the detection part 11 of the probe and the water quality. The UV lamp 3 can be powered by a power cord or a wireless power lamp.

[0045] In some embodiments, the ultraviolet lamp 3 can be installed in the pipe 242 by means of a threaded connection.

[0046] The water quality detection probe may also include a controller, which is connected to the detection part 11 and the ultraviolet lamp 3 respectively, and the controller controls the detection part 11 and the ultraviolet lamp 3 to work alternately. In the actual operation process, when the detection part 11 starts to work, the controller will automatically turn off the ultraviolet lamp 3 to ensure that it is not interfered by ultraviolet light during the detection period. After the detection part 11 finishes working, the controller will automatically turn on the ultraviolet lamp 3. This design avoids the influence of the ultraviolet lamp 3 on the stability of water quality index detection, thereby ensuring the accuracy and reliability of water quality detection. The controller can be an electronic two-way selection switch, one of the selection states of the electronic two-way selection switch is to select that the circuit of the ultraviolet light 3 is powered, so the ultraviolet lamp 3 is in a working state; another selection state of the electronic two-way selection switch is to select that the circuit of the detection part 11 is powered, so the detection part 11 is in a working state, and the ultraviolet light 3 is in a non-working state with power off.

[0047] When using the water quality detection probe of the utility model, the probe body 1 is first installed in the water body to be monitored, so that the detection part 11 is completely immersed in the water. At the same time, the protective cover 2 is installed on the probe body 1, and the detection part 11 is completely wrapped inside the protective cover 2, and the ultraviolet lamp 3 is also installed in the protective cover 2 and the position of the ultraviolet lamp 3 is adjusted so that the ultraviolet lamp 3 is aligned with the detection part 11. Then turn on the ultraviolet lamp 3 so that it emits ultraviolet light, and the ultraviolet light is irradiated on the detection part 11, so as to inhibit the growth of algae and fungi on the detection part 11 and ensure the cleanliness of the detection part 11. At the same time, if the detection part 11 needs to detect water quality parameters, the controller will first turn off the ultraviolet lamp 3, and then start the detection part 11 to detect the water quality. And the detected data such as ammonia nitrogen, pH value and other detection results are transmitted to a display or computer and other devices through a data line or wireless signal, so as to realize the monitoring of water quality.

[0048] The utility model has a simple structure, ingenious design, is easy to manufacture and install, and can effectively inhibit the growth of algae and fungi on the detection part 11, thereby improving the accuracy of water quality detection without increasing the manufacturing cost and maintenance cost of the probe.
