Description

Technical Field

[0001] This application relates to the field of water quality analyzer technology, and more specifically, to a water quality analyzer for hydrogeological exploration. Background Technology

[0002] Water quality analyzers play a crucial role in hydrogeological exploration. Portable water quality analyzers are suitable for rapid field testing and can simultaneously measure indicators such as COD, ammonia nitrogen, total phosphorus, total nitrogen, heavy metals (such as lead, mercury, and cadmium), dissolved oxygen, and pH. Portable water quality analyzers mainly use immersion probes, which are placed into rivers or water cups for sampling.

[0003] However, during the use of the immersion probe, it was found that when the immersion probe was inserted into the water cup, it would tip over due to the large size of the probe head and the low height of the water cup. Therefore, the testing personnel need to hold the probe in place during use.

[0004] In view of this, we propose a water quality analyzer for hydrogeological exploration. Utility Model Content

[0005] Technical problems to be solved

[0006] The purpose of this application is to provide a water quality analyzer for hydrogeological exploration, which solves the technical problems in the background art mentioned above, and realizes the problem of avoiding the water cup from tipping over when the immersion probe is used to analyze the water quality of the water sample in the water cup by means of a support rod and support legs.

[0007] Technical solution

[0008] This application provides a water quality analyzer for hydrogeological exploration, including an analyzer body and an immersion probe. The head of the immersion probe is rotatably equipped with support rods on both sides. The lower end of the support rods is rotatably connected to two support legs. The included angle between the two support legs is adjustable. The opposite sides of the two support legs are provided with storage grooves.

[0009] As an optional solution to the technical solution of this application, one end of the support leg is rotatably connected to a positioning shaft that passes through the lower end of the support rod, and a nut is fixed between the two positioning shafts, with a screw threaded onto the nut that abuts against the support rod.

[0010] As an optional solution to the technical solution of this application, mounting openings are reserved on both sides of the head, and a shaft is fixed at the end of the support rod away from the support leg. The shaft is rotatably set in the shaft hole opened in the head. Multiple retaining balls are fixed on the support rod and distributed around the shaft. Multiple retaining grooves are distributed in a ring around the shaft hole on the inner wall of the mounting opening.

[0011] As an optional solution to the technical solution of this application, the support leg is two-sectioned, and the two support legs are fixed together by a connecting shaft, on which a suction cup is rotatably connected.

[0012] As an optional solution to the technical solution in this application, a rubber pad is fixed to one side of the support leg.

[0013] As an optional solution to the technical solution of this application, the two supporting legs are each fixed with meshing gears at their close ends, and the positioning shaft passes through the gears coaxially. Beneficial effects

[0014] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0015] 1. In this application, the head of the immersion probe is supported outward by a support rod that is rotatably set on both sides. Then, the lower end of the support rod is rotated to connect two support legs. After the included angle between the two support legs is adjusted, when the detection rod of the immersion probe is immersed in the water sample cup and tilted, the tilted immersion probe is supported by the T-shaped support rod and support legs, thereby improving the stability of the immersion probe in the tilted state.

[0016] 2. In this application, two support legs are fixed with meshing gears at their close ends, and a positioning shaft passes through the gears coaxially. When one support leg is started to rotate around the positioning shaft, the meshing of the two gears causes the other support leg to flip, thus facilitating quick and easy adjustment of the two support legs.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] like Figure 1 - Figure 10As shown, a water quality analyzer for hydrogeological exploration includes an analyzer body 10 and an immersion probe 20. The immersion probe 20 is supported outwards by support rods 30 rotatably mounted on both sides of its head 21. Two support legs 40, rotatably connected to the lower ends of the support rods 30, are then rotated. The angle between the two support legs 40 is adjustable. When the two support legs 40 are adjusted to form an inverted T-shape with respect to the support rods 30, receiving grooves 33 are provided on opposite sides of the two support legs 40. When immersed... When the detection rod 22 of the immersion probe 20 is immersed in the water sample cup and tilted, the tilted immersion probe 20 is supported by the T-shaped support rod 30 and support leg 40. Simultaneously, the storage groove 33 on the inner side of the support leg 40 facilitates the storage of the tilted support leg 40, and when one side of the support rod 30 is tilted, the side wall of the storage groove 33 on the other side of the support rod 30 rests against the rim of the water sample cup, thus improving the stability of the immersion probe 20 in the tilted state (e.g., ...). Figure 10 (as shown)

[0033] The two support rods 30 are supported outwards, while the included angle between the two support legs 40 is adjusted to an inverted V-shape. Then, the detection rod 22 is immersed in the river water, and the two sets of inverted V-shaped support legs 40 support the detection rod 22 to prevent the lower end of the detection rod 22 from touching the bottom (e.g., Figure 9 As shown in the figure, the immersion probe 20 can also be suspended in the water sample cup in this state.

[0034] like Figure 3 , Figure 6 As shown, a positioning shaft 34 is rotatably connected to one end of the support leg 40, passing through the lower end of the support rod 30. The positioning shaft 34 is placed at one end of the support leg 40 and a limit ring is fixed coaxially to prevent the positioning shaft 34 from falling off the support leg 40. Nuts 341 are fixed at the ends of the two positioning shafts 34 away from the limit rings. A screw 35 that abuts against the support rod 30 is threaded onto the nut 341. By rotating the screw 35 clockwise, the screw 35 and the nut 341 are pressed against the support rod 30 by the thread action. Thus, under the action of compression and / or friction, the two angle-adjusted support legs 40 are fixed to the lower end of the support rod 30 through the positioning shaft 34, so as to quickly fix the two support legs 40.

[0035] like Figure 5 , Figure 8As shown, mounting openings 211 are reserved on both sides of the head 21. The upper end of the support rod 30 is placed in the mounting opening 211, and the upper end of the support rod 30 is fixed with a shaft 31. The shaft 31 is rotatably set in the shaft hole 212 opened in the head 21 and rotates around the shaft hole 212. Multiple retaining balls 32 are fixed on the support rod 30 and distributed around the shaft 31. Multiple retaining grooves 213 are distributed in a ring around the inner wall of the mounting opening 211 and the shaft hole 212. When the support rod 30 rotates around the fixed shaft 31, the rubber retaining balls 32 are squeezed and inserted into the corresponding retaining grooves 213. In this way, the angle between the rotated support rod 30 and the head 21 can be positioned.

[0036] like Figure 2 , Figure 6 As shown, the support leg 40 has a two-section structure, and the two sections of the support leg 40 are fixed together by a connecting shaft 41. The connecting shaft 41 passes through the connecting hole 421 opened at the upper end of the suction cup 42. The suction cup 42 is rotatably connected to the connecting shaft 41. Therefore, when the water sample cup is placed on a smooth table, the angle can be adjusted by rotating the suction cup 42 and the connecting hole 421, and then the suction cup 42 can be adsorbed onto the table, thereby improving the fixation reliability between the support leg 40 and the table, and thus increasing the support stability of the support leg 40 and the support rod 30 for the immersion probe 20.

[0037] like Figure 6 As shown, by fixing a rubber pad 44 to one side of the support leg 40, when the support leg 40 is supported on the ground, the rubber pad 44 can increase the coefficient of friction between the support leg 40 and the ground, thus preventing the support leg 40 from slipping.

[0038] like Figure 3 As shown, two support legs 40 are fixed with meshing gears 43 at their close ends. The positioning shaft 34 passes through the gears 43 coaxially. When one support leg 40 is started to rotate around the positioning shaft 34, the meshing action of the two gears 43 drives the other support leg 40 to rotate, thus facilitating quick adjustment of the two support legs 40.

[0039] Working principle: When the immersion probe 20 is used in the water sample cup, one of the support rods 30 is flipped outwards, and the other support rod 30 is flipped outwards around the shaft 31. The screw 35 is rotated counterclockwise to loosen the support leg 40, which is then flipped outwards around the connecting shaft 41. Under the meshing action of the gear 43, the two support legs 40 are at 180 degrees. The screw 35 is then rotated clockwise, pressing against the support rod 30. Under the action of compression and / or friction, the support leg 40 is fixed to the lower end of the support rod 30. The detection rod 22 is tilted against the opening side of the water sample cup. Then, the angle of the support rod 30 on that side is adjusted so that the support leg 40 is supported on the table or the ground.
