Description

Technical Field

[0001] The utility model relates to the technical field of water quality detectors, in particular to a water quality detector capable of winding up cables. Background Art

[0002] The core contents of environmental engineering include the control of environmental pollution sources, air pollution prevention and control, water pollution prevention and control, solid waste treatment and utilization, comprehensive environmental pollution prevention and control, and environmental system engineering. In the process of water pollution prevention and control, it is necessary to use water quality detectors to detect the ion concentration, hardness and pH value in water. The existing water quality detectors still have certain defects when used.

[0003] There are many methods for water quality detection in the prior art. Detecting the concentration of specific ions in water by measuring the changes in electrode potential or current is a common water quality detection method. Since the cable on the water quality detector is long and difficult to roll up, the cable needs to be picked up separately when carrying the water quality detector. Utility Model Content

[0004] The utility model aims to provide a water quality detector with a cable that can be rolled up, so as to solve the problem that the cable of the water quality detector on the current market is difficult to roll up, as mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a water quality detector capable of winding up a cable, comprising: an instrument body, a display screen, an operation button, a cable body and a conductivity sensor, wherein the display screen and the operation button are respectively installed on the surface of the instrument body, the back of the instrument body is connected to the cable body, and the end of the cable body is connected to the conductivity sensor.

[0006] Preferably, the back of the instrument body is connected to a storage rod, the outer side of the storage rod is connected to a limiting block, the back of the instrument body close to the storage rod is connected to a connecting block, the inside of the connecting block is connected to a spring, and the ends of the two springs are commonly connected to a pressure plate.

[0007] Preferably, a through hole is formed inside the pressure plate, a connecting plate is installed on the back of the instrument body, and a limiting rod is inserted inside the connecting plate.

[0008] Preferably, a plug-in structure is formed between the limiting rod and the pressing plate through a through hole, and the limiting rod is in a T-shape.

[0009] Preferably, a stopper is connected to the outer side of the instrument body, and a rubber block is bonded to the outer side of the instrument body close to the conductivity sensor.

[0010] Preferably, a fixing plate is installed on the same side of the instrument body away from the stopper, a telescopic rod is installed on the side of the fixing plate close to the conductivity sensor, and the end of the telescopic rod is connected to a moving block.

[0011] Preferably, a protective cover is installed on a side of the moving block close to the conductivity sensor, and a sliding rod is connected to the front of the protective cover.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: for the water quality detector capable of winding up the cable, when the cable body is completely wound around the storage rod, the limit rod can be pulled upward, and when the limit rod moves, it can slide out from the inside of the connecting plate, at which time the limit rod no longer limits the pressure plate, so that the pressure plate can be reset by the compressed spring, and when the end of the protective cover moves to the surface of one side of the block, the protective cover can completely cover the conductivity sensor, and the conductivity sensor can be shielded by the protective cover, so that dust is not easy to accumulate on the surface of the conductivity sensor, and the conductivity sensor can be protected at the same time.

[0013] 1. The water quality detector can detect the ion concentration of the water source, but it is difficult to reel in and fix the cable body during the carrying process. When the cable body is completely reeled in and wrapped around the storage rod, the limit rod can be pulled upward. When the limit rod moves, it can slide out from the inside of the connecting plate. At this time, the limit rod no longer limits the pressure plate, so that the pressure plate can be reset by the compressed spring. When the pressure plate is reset, the cable body reeled in and wrapped around the storage rod can be squeezed and limited, so that the cable body on the storage rod is not easy to loosen. The cable body can be reeled in and placed through the storage rod, and the cable body is placed more neatly. At the same time, there is no need to take the cable body separately during the carrying of the instrument body.

[0014] 2. The conductivity sensor on the water quality detector is usually directly exposed to the outside world, which causes dust to accumulate on the surface of the conductivity sensor during placement, thereby affecting the accuracy of its detection. When the moving block moves, it can drive the protective cover to move. When the protective cover moves, it can drive the sliding rod to move. When the sliding rod moves, it can slide through the fixed plate, and the end of the telescopic rod can be stretched while the moving block moves. When the end of the protective cover moves to the surface of one side of the block, the protective cover can completely cover the conductivity sensor. The conductivity sensor can be shielded by the protective cover, so that dust is not easy to accumulate on the surface of the conductivity sensor, and the conductivity sensor can be protected at the same time.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 2 , Figure 3 and Figure 5 It can be seen that the utility model provides a technical solution: a water quality detector that can reel in a cable, comprising: an instrument body 1, a display screen 2, an operation button 3, a cable body 4 and a conductivity sensor 5, the display screen 2 and the operation button 3 are respectively installed on the surface of the instrument body 1, the back of the instrument body 1 is connected to the cable body 4, the end of the cable body 4 is connected to the conductivity sensor 5, the back of the instrument body 1 is connected to a storage rod 6, the outer side of the storage rod 6 is connected to a limiting block 7, the back of the instrument body 1 close to the storage rod 6 is connected to a connecting block 8, the interior of the connecting block 8 is connected to a spring 9, the ends of the two springs 9 are commonly connected to a pressure plate 10, the interior of the pressure plate 10 is penetrated by a through hole 11, a connecting plate 12 is installed on the back of the instrument body 1, a limiting rod 13 is inserted into the interior of the connecting plate 12, and a plug-in structure is formed between the limiting rod 13 and the pressure plate 10 through the through hole 11, and the shape of the limiting rod 13 is T-shaped.

[0024] During specific implementation, the water quality detector can detect the ion concentration of the water source, but it is difficult to roll up and fix the cable body 4 during the carrying process of the water quality detector. For this reason, the cable body 4 can be manually rolled up and wrapped around the storage rod 6. The limit block 7 can prevent the cable body 4 from shifting. When the cable body 4 is completely rolled up and wrapped around the storage rod 6, the limit rod 13 can be pulled upward. When the limit rod 13 moves, it can slide out from the inside of the connecting plate 12. At the same time, the limit rod 13 can slide out from the inside of the pressure plate 10 through the through hole 11. At this time, the limit rod 13 no longer limits the pressure plate 10, so that the pressure plate 10 can be reset by the compressed spring 9. When the pressure plate 10 is reset, the cable body 4 rolled up and wrapped on the storage rod 6 can be squeezed and limited, so that the cable body 4 on the storage rod 6 is not easy to loosen.

[0025] See also Figure 2 , Figure 3 and Figure 5 It can be seen that the cable body 4 can be rolled up and placed by the storage rod 6, and the cable body 4 is placed more neatly. At the same time, when the instrument body 1 is carried, there is no need to take the cable body 4 separately.

[0026] See also Figure 1 , Figure 2 , Figure 4 and Figure 6 It can be seen that a stopper 14 is connected to the outer side of the instrument body 1, a rubber block 15 is bonded to the outer side of the instrument body 1 close to the conductivity sensor 5, a fixing plate 16 is installed on the same side of the instrument body 1 away from the stopper 14, a telescopic rod 17 is installed on the side of the fixing plate 16 close to the conductivity sensor 5, a moving block 18 is connected to the end of the telescopic rod 17, a protective cover 19 is installed on the side of the moving block 18 close to the conductivity sensor 5, a sliding rod 20 is connected to the front of the protective cover 19, and a sliding structure is formed between the sliding rod 20 and the fixing plate 16.

[0027] In specific implementation, the conductivity sensor 5 on the water quality detector is usually directly exposed to the outside world, which causes dust to accumulate on the surface of the conductivity sensor 5 during placement, thereby affecting the accuracy of its detection. For this reason, the conductivity sensor 5 can be stuck inside the rubber block 15, and the cable body 4 can be moved to the inner side of the stopper 14. At this time, the moving block 18 can be pushed. When the moving block 18 moves, the protective cover 19 can be driven to move. When the protective cover 19 moves, the sliding rod 20 can be driven to move. When the sliding rod 20 moves, it can slide through the fixed plate 16. When the moving block 18 moves, the end of the telescopic rod 17 can be stretched, so that the end of the telescopic rod 17 can move with the moving block 18. When the end of the protective cover 19 moves to the surface of one side of the stopper 14, the protective cover 19 can completely cover the conductivity sensor 5.

[0028] See also Figure 1, Figure 2 , Figure 4 and Figure 6 It can be seen that the conductivity sensor 5 can be shielded by the protective cover 19, so that dust is not easily accumulated on the surface of the conductivity sensor 5, and the conductivity sensor 5 can be protected at the same time.

[0029] In summary, when using the water quality detector that can reel in the cable, place the end of the conductivity sensor 5 in the water source. There are two electrodes at the end of the conductivity sensor 5. When water passes through the two electrodes, a conductivity measurement path is formed between them. The conductivity sensor 5 measures the current passing through the water and calculates the conductivity with the ratio of the voltage. The conductivity can be viewed on the display screen 2. The greater the conductivity, the more ions there are in the water source, and the smaller the conductivity, the fewer ions there are in the water source. The water quality detector is a prior art and will not be described in detail here. When the pressing plate 10 is reset, the cable body 4 wound on the storage rod 6 can be reeled in. The extrusion limit makes it difficult for the cable body 4 on the storage rod 6 to become loose. The cable body 4 can be rolled up and placed through the storage rod 6, and the cable body 4 is placed more neatly. At the same time, when the instrument body 1 is carried, there is no need to take the cable body 4 separately. When the end of the protective cover 19 moves to the surface of one side of the stopper 14, the protective cover 19 can completely cover the conductivity sensor 5. The conductivity sensor 5 can be shielded by the protective cover 19, so that dust is not easy to accumulate on the surface of the conductivity sensor 5. At the same time, the conductivity sensor 5 can be protected. The contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
