Description

Technical Field

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

[0002] In order to strengthen the monitoring of water environment quality, the water quality in rivers is often monitored.

[0003] Currently, existing technologies for monitoring water quality in rivers typically involve first extracting water from the river and then testing it using a water quality monitoring instrument. For example, Chinese patent CN 217587177 U discloses a water quality monitoring device for environmental engineering. This device has a connecting part fixed to the outer wall of the detection tube, and an inlet pipe installed on the side wall of the detection tube. A sealing piston is installed in the detection tube. A pull plate and a pull rod drive the sealing piston to move, allowing water to enter the detection tube from the inlet pipe and come into contact with the water quality monitoring instrument along the connecting part. This improves the convenience of water quality monitoring.

[0004] However, in actual use, after each water quality monitoring, the device needs to be cleaned before the next monitoring can be completed to ensure the accuracy of the water quality monitoring. Therefore, the piston needs to be removed frequently, which will accelerate the wear of the piston and reduce its service life and sealing performance. In view of this, a water quality monitoring device is proposed. Utility Model Content

[0005] The main objective of this invention is to provide a water quality monitoring device that can solve the problems mentioned in the background section.

[0006] To achieve the above objectives, the water quality monitoring device proposed in this utility model includes a cylindrical body, a top cover threadedly connected to the top of the cylindrical body, a water inlet pipe fixedly connected to the bottom of the cylindrical body, a water intake mechanism disposed within the cylindrical body, and a water quality monitoring instrument fixedly installed on the back of the cylindrical body. The water intake mechanism includes:

[0007] A piston head is slidably connected to the inner wall of the cylinder, and an elastic sealing ring is embedded in the outer wall of the piston head.

[0008] A pull rod is fixedly connected to the upper side of the piston head, and a positioning protrusion is fixedly connected to the outer wall of the pull rod;

[0009] And a push rod, which passes through the pull rod and is slidably connected to the pull rod.

[0010] Preferably, a fixed chamber is embedded inside the piston head, and an air chamber is opened in the fixed chamber. A piston block is connected to the piston in the fixed chamber. A hinge rod is hinged to the side of the piston block near the press rod, and the end of the hinge rod away from the piston block is hinged to the press rod.

[0011] Preferably, the air chamber is located on the side of the piston block away from the hinge rod. The air chamber is connected to an air pipe, and the end of the air pipe away from the air chamber is connected to the elastic sealing ring. By pressing the push rod, the push rod moves downward, driving the hinge rod to move. This causes the piston block to squeeze the gas in the air chamber through the air pipe into the elastic sealing ring, causing the elastic sealing ring to expand and thus improving the sealing effect of the piston head.

[0012] Preferably, a positioning groove is provided on the outer wall of the top cover, and the positioning protrusion is slidably connected in the positioning groove.

[0013] Preferably, the top of the pull rod has a notch, and the push rod is elastically connected to the notch by a connecting spring.

[0014] Preferably, the inner wall of the bottom of the cylinder is in the shape of an inverted frustum, which allows the water in the cylinder to be discharged more thoroughly.

[0015] This utility model provides a water quality monitoring device. It has the following beneficial effects:

[0016] (1) The water quality monitoring equipment uses a water intake mechanism so that the elastic sealing ring is not in an expanded state during the process of removing the piston head, thereby reducing the friction between the piston head and the inner wall of the cylinder, thus reducing the wear of the piston head and improving the service life of the piston head. At the same time, during the water intake process, by pressing the push rod, the push rod moves downward, driving the hinge rod to move, and then the piston block squeezes the gas in the air chamber into the elastic sealing ring through the air pipe, causing the elastic sealing ring to expand, thereby improving the sealing effect of the piston head.

[0017] (2) The water quality monitoring equipment uses positioning protrusions and positioning grooves to make the positioning protrusions slide in the positioning grooves during the up and down movement of the pull rod, ensuring the stability of the piston head lifting and lowering, preventing the piston head from rotating, and further reducing the wear of the piston head.

[0026] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 This utility model proposes a water quality monitoring device, including a cylinder 1. The inner wall of the bottom of the cylinder 1 is inverted frustum shape, which facilitates drainage. A top cover 2 is threaded to the top of the cylinder 1, and a water inlet pipe 3 is fixedly connected to the bottom of the cylinder 1. A water intake mechanism 4 is provided in the cylinder 1, and a water quality monitor is fixedly installed on the back of the cylinder 1. The water quality monitor is existing technology and can monitor water quality.

[0029] In this embodiment of the utility model, in order to monitor water quality, the water intake mechanism 4 specifically includes a piston head 41, a pull rod 43, and a push rod 45. The piston head 41 is slidably connected to the inner wall of the cylinder 1, and an elastic sealing ring 42 is embedded in the outer wall of the piston head 41. The pull rod 43 is fixedly connected to the upper side of the piston head 41, and a positioning protrusion 44 is fixedly connected to the outer wall of the pull rod 43. The push rod 45 passes through the pull rod 43 and is slidably connected to the pull rod 43. By pulling the pull rod 43, the piston head 41 moves upward, drawing the water to be monitored into the cylinder 1, and then the water quality is monitored by a water quality monitor.

[0030] Furthermore, to improve the sealing performance during water intake, specifically, a fixed chamber 411 is embedded inside the piston head 41. An air chamber 412 is formed within the fixed chamber 411. A piston block 414 is connected to the piston in the fixed chamber 411. A hinge rod 415 is hinged to the side of the piston block 414 near the push rod 45. The end of the hinge rod 415 away from the piston block 414 is hinged to the push rod 45. The air chamber 412 is located on the side of the piston block 414 away from the hinge rod 415. An air pipe 413 is connected to the air chamber 412. The end of the air pipe 413 away from the air chamber 412 is connected to an elastic sealing ring 42. A notch is formed at the top of the pull rod 43. The push rod 45 is elastically connected to the notch via a connecting spring. Pressing the push rod... When lever 45 moves downward, it drives hinge lever 415 to move. This causes piston block 414 to compress the gas in air chamber 412 and allow it to enter elastic sealing ring 42 through air pipe 413. This causes elastic sealing ring 42 to expand, making piston head 41 in close contact with the inner wall of cylinder 1. This improves the sealing effect of piston head 41 when taking water. When piston head 41 needs to be removed for cleaning, releasing lever 45 causes the connecting spring to reset lever 45. This causes hinge lever 415 to pull piston block 414 back to its original position, allowing gas in elastic sealing ring 42 to enter air chamber 412. Elastic sealing ring 42 then contracts, reducing wear on piston head 41 during movement and extending the service life of piston head 41.

[0031] In addition, in order to further reduce the wear of piston head 41, a positioning groove 21 is provided on the outer wall of top cover 2, and positioning protrusion 44 is slidably connected in positioning groove 21. Through the use of positioning protrusion 44 and positioning groove 21, the positioning protrusion 44 slides in positioning groove 21 during the up and down movement of pull rod 43, ensuring the stability of piston head 41 in raising and lowering, and preventing piston head 41 from rotating, thereby further reducing the wear of piston head 41.

[0032] It should be noted that the above electrical components are all existing technology products. They are selected, installed and debugged by those skilled in the art according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. The applicant does not impose any specific restrictions here.

[0033] In use, pull the lever 43 to move the piston head 41 upward, drawing the water to be monitored into the cylinder 1. The water quality is then monitored by a water quality monitor. During this process, press the lever 45, which moves downward, causing the hinge lever 415 to move. This causes the piston block 414 to compress the gas in the air chamber 412 and enter the elastic sealing ring 42 through the air pipe 413, causing the elastic sealing ring 42 to expand and making the piston head 41 in close contact with the inner wall of the cylinder 1. After monitoring is completed, release the lever 45, and the connecting spring will reset the lever 45. Then, the hinge lever 415 will pull the piston block 414 back to its original position, allowing the gas in the elastic sealing ring 42 to enter the air chamber 412. The elastic sealing ring 42 will contract, reducing wear on the piston head 41 during movement. At the same time, remove the top cover 2 to clean the device without affecting subsequent water quality monitoring.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
