[0002] 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, and evaluating the water quality status. The monitoring scope is very wide, including unpolluted and polluted natural water (rivers, lakes, seas and groundwater) and various industrial drainage. The main monitoring items can be divided into two categories, one is the comprehensive indicators reflecting the water quality status, and the other is some toxic substances. When monitoring water quality, water quality monitoring instruments are usually used.

[0003] In the prior art, there is a device for fixing the probe of an online water quality monitoring instrument with patent announcement number CN215812712U. The above patent turns on the electric telescopic rod, which drives the adjustment block to move upward. The adjustment block finally drives the two clamping rods to move toward each other, and the clamping rod drives the two clamping seats to move toward each other, so as to fix the probe of the online water quality monitoring instrument. The device for fixing the probe of the online water quality monitoring instrument has the advantage of good fixation. In actual use, it is convenient for users to fix the probe of the online water quality monitoring instrument. However, there are still the following shortcomings in actual use: the outer surface of some probes is usually made of soft material, and it is easy to over-clamp the probe when fixing the probe, thereby causing damage to the sensor inside the probe, and there are many stones in the water flow in the wild. The probe is easily impacted by the stones in the water, causing damage to the probe.

[0004] Therefore, a fixing device for a probe of a water quality monitoring instrument is needed to solve the problems in the prior art that the fixing device is prone to over-clamping the probe and stones in the water flow are prone to hitting the probe and causing damage to the probe. Utility Model Content

[0005] The purpose of the utility model is to provide a fixing device for a probe of a water quality monitoring instrument to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fixing device for a probe of a water quality monitoring instrument, comprising a mounting tube, movable grooves are provided on both sides of the outer surface of the mounting tube, an electric push rod is fixedly connected to the top of the mounting tube by bolts, a moving block is coaxially fixedly connected to the output end of the electric push rod, and a fixing mechanism is provided at the bottom end of the moving block;

[0007] The fixing mechanism includes an installation groove, which is opened at the bottom end of the movable block. Two symmetrically distributed connecting rods are rotatably connected between the two end walls inside the installation groove through a rotating shaft. The end of the connecting rod away from the installation groove is hinged with a clamping rod through a pin shaft. The outer walls at both ends of the two clamping rods are rotatably connected to the two end walls inside the bottom ends of the two movable grooves through a rotating shaft. An arc-shaped clamping block is fixedly connected to the bottom surface of the clamping rod, and a buffer assembly is arranged inside the two arc-shaped clamping blocks.

The outer walls on one side of the two sliding rods located outside the arc-shaped clamping block are fixedly connected to the same arc-shaped clamping plate.

[0009] It is further worth explaining that the bottom surfaces of the two arc-shaped clamping blocks are fixedly connected to two parallel vertical rods, and the bottom ends of the two vertical rods located on the same bottom surface of the arc-shaped clamping block are fixedly connected to the same arc-shaped protective shell, and the outer surface of the arc-shaped protective shell is penetrated by a plurality of circumferentially distributed water holes.

[0013] Compared with the prior art, the fixing device for a probe of a water quality monitoring instrument provided by the utility model has at least the following beneficial effects:

[0014] (1) Through the action of the fixing mechanism, the electric push rod is started to drive the moving block to rise, so that the two arc-shaped clamping blocks are opened, and the probe is placed between the two arc-shaped clamping plates. The electric push rod is started to drive the moving block to descend, so that the two arc-shaped clamping blocks are close to each other, and the probe is clamped and fixed.

[0015] (2) By setting up two arc-shaped protective shells, after the probe is fixed, the bottom end of the probe is located between the protective covers formed by the two arc-shaped protective shells. The probe is placed in the water flow, and the water flows through multiple water holes. Stones in the water collide with the outer surface of the arc-shaped protective shell along with the water flow, which effectively avoids the problem of stones in the water flow easily hitting the probe and causing damage to the probe.

[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] See also Figure 1-Figure 4 The utility model provides a fixing device for a probe of a water quality monitoring instrument, comprising a mounting tube 1, movable grooves 2 are provided on both sides of the outer surface of the mounting tube 1, an electric push rod 3 is fixedly connected to the top of the mounting tube 1 by bolts, a moving block 4 is coaxially fixedly connected to the output end of the electric push rod 3, and a fixing mechanism 5 is provided at the bottom end of the moving block 4;

[0023] The fixing mechanism 5 includes a mounting groove 51, which is opened at the bottom end of the movable block 4. Two symmetrically distributed connecting rods 52 are rotatably connected between the two end walls inside the mounting groove 51 through a rotating shaft. The end of the connecting rod 52 away from the mounting groove 51 is hinged with a clamping rod 53 through a pin shaft. The outer walls at both ends of the two clamping rods 53 are rotatably connected to the inner end walls at the bottom ends of the two movable grooves 2 through a rotating shaft. An arc-shaped clamping block 54 is fixedly connected to the bottom surface of the clamping rod 53, and a buffer assembly 55 is arranged inside the two arc-shaped clamping blocks 54.

[0024] Further as Figure 3 and Figure 4 As shown, it is worth explaining in detail that the buffer assembly 55 includes two parallel cavities 551, and the two cavities 551 are both opened inside the arc-shaped clamping block 54. The inner walls of the two cavities 551 are both slidably connected to the limiting plate 552, and the outer wall on one side of the limiting plate 552 is fixedly connected with a spring 553, and the side of the spring 553 away from the limiting plate 552 is fixedly connected to the one side wall inside the cavity 551, and the outer wall on the other side of the limiting plate 552 is coaxially fixedly connected with a slide rod 554, and the two slide rods 554 located in the same arc-shaped clamping block 54 are located away from the limiting plate 552. The outer wall on one side of the two slide rods 554 located outside the arc-shaped clamping block 54 is fixedly connected with the same arc clamping plate 555.

[0025] Further as Figure 1 and Figure 3 As shown, it is worth explaining in detail that the bottom surfaces of the two arc-shaped clamping blocks 54 are fixedly connected to two parallel vertical rods 6, and the bottom ends of the two vertical rods 6 located on the bottom surface of the same arc-shaped clamping block 54 are fixedly connected to the same arc-shaped protective shell 7, and the outer surface of the arc-shaped protective shell 7 is penetrated by a plurality of water holes 8 distributed in a circular pattern.

[0026] Further as Figure 1 and Figure 3 As shown, it is worth explaining in detail that a plurality of evenly distributed protrusions 9 are fixedly connected to the outer wall of the arc-shaped clamping plate 555 away from the slide rod 554, and a mounting frame 10 for connecting with an external device is fixedly connected to the top of the mounting tube 1.

[0027] Further as Figure 1 and Figure 2 As shown, it is worth explaining in detail that the mounting tube 1 is coaxially arranged with the electric push rod 3, and the moving block 4 is protected by the mounting tube 1 to prevent the moving block 4 from being interfered with externally when moving, and the connecting rod 52 is arranged in an inclined shape to ensure that the moving block 4 can push the two connecting rods 52 to rotate toward the two sides of the mounting tube 1 respectively.

[0028] Further as Figure 1 and Figure 3 As shown, it is worth explaining in detail that the clamping rod 53 is set to a V-shaped structure, so that the clamping rod 53 can drive the arc clamping block 54 to rotate as the connecting rod 52 rotates. The inner diameter of the arc clamping block 54 is the same as the outer diameter of the arc clamping plate 555, thereby avoiding interference of the arc clamping block 54 when the arc clamping plate 555 moves.

[0029] In summary, when the fixing device is in use, the electric push rod 3 is first turned on to drive the moving block 4 to move upward. When the moving block 4 moves upward, it drives the two connecting rods 52 to move upward. Under the hinged action, the two connecting rods 52 drive the two clamping rods 53 to rotate in opposite directions. At this time, the two arc-shaped clamping blocks 54 respectively drive the two arc-shaped clamping plates 555 to be in an open state, and the water quality monitoring instrument probe is placed between the two arc-shaped clamping plates 555. The electric push rod 3 is turned on again to drive the moving block 4 to descend. Similarly, the two arc-shaped clamping blocks 54 respectively drive the two arc-shaped clamping plates 555 to approach each other. When the arc-shaped clamping plates 55 When the arc clamping plate 555 gradually contacts the outer surface of the probe, the arc clamping plate 555 is forced to push the limit plate 552 to slide in the cavity 551, and the spring 553 is used for buffering. When the two arc clamping blocks 54 move to the outer walls of one side close to the two arc protective shells 7 and fit each other, the probe is fixed. At the same time, the plurality of protrusions 9 arranged on the outer wall of the side where the arc clamping plate 555 contacts the probe increase the friction between the arc clamping plate 555 and the outer surface of the probe, thereby improving the fixing effect of the arc clamping plate 555 on the probe, and effectively avoiding the problem that the fixing device is easy to over-clamp the probe and cause damage to the probe.

[0030] After the probe is fixed by the fixing mechanism 5, the outer walls of the two adjacent arc-shaped protective shells 7 fit together, and the two arc-shaped protective shells 7 form a protective cover. The bottom end of the probe is located between the protective covers formed by the two arc-shaped protective shells 7. When monitoring the water quality in the wild, the probe is placed in the water flow, and the water flows through multiple water holes 8. Stones in the water collide with the outer surface of the arc-shaped protective shell 7 along with the water flow, which effectively avoids the problem of stones in the water flow easily hitting the probe and causing damage to the probe.

[0031] The electric push rod 3 can be purchased on the market. The electric push rod 3 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it is not repeated in the specification.
