Technical Field
[0001] This utility model relates to the field of water quality monitoring technology, specifically to a water sample collection device for online monitoring of water quality from pollution sources. Background Technology
[0002] Water quality monitoring involves monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants, and their changing trends. During water quality monitoring, it is necessary to regularly collect water samples from polluted water sources.
[0003] For example, announcement number CN214471929U, entitled "Water Sampling Device," includes a sampling bottle and a telescopic rod. The sampling bottle comprises a bottle body and a handle movably connected to the bottle body. The bottle body can rotate relative to the handle to allow for horizontal placement for sampling. One end of the telescopic rod is connected to the handle via a steering mechanism, making the angle of the telescopic rod and the handle adjustable. This sampling device allows for adjustment of the angle of the telescopic rod and the handle, as well as the length of the telescopic rod, to a suitable length based on the depth and location of the sampling point, enabling the sampling bottle to be placed in the water body for sampling. During water sampling, the sampling bottle can be placed horizontally, thus avoiding disturbance to the water body and reducing the possibility of other impurities in the water sample interfering with water quality testing.
[0004] The existing water sampling device has the following drawbacks: 1. The device requires manual placement and retrieval, making it inconvenient to use; 2. The device only has a single inlet, and the inlet lacks a filtration structure, so the water cannot be discharged once it is full, which can easily cause blockage. Therefore, it does not meet the current needs, and a water sampling device for online monitoring of pollution source water quality is proposed. Utility Model Content
[0005] The purpose of this invention is to provide an online water sample collection device for monitoring water quality of pollution sources, so as to solve the problems mentioned in the background art: the existing water sample collection devices are inconvenient for users to place and pick up, and the sampling port is easy to be blocked, and the internal water cannot be discharged.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an online water quality monitoring and sampling device for pollution sources, comprising: an outer shell, an assembly frame mounted on the top of the outer shell, an electric telescopic rod mounted on the top of the assembly frame, an inner lifting cylinder mounted on the telescopic end of the electric telescopic rod, the inner lifting cylinder being located inside the outer shell, a sampling inlet and a sampling outlet respectively opened on the outer walls at the front and rear ends of the inner lifting cylinder, the height of the sampling outlet being lower than that of the sampling inlet, a mesh cover being provided on the outer walls of both the sampling inlet and the sampling outlet, a measuring cylinder being installed inside the inner lifting cylinder, and a water quality monitoring component being mounted on the top of the assembly frame.
[0007] Preferably, the front end face of the measuring cylinder is equipped with an inlet channel connected to the sampling inlet, and the rear end face of the measuring cylinder is equipped with a drain valve connected to the sampling outlet.
[0008] Preferably, the water quality monitoring device includes a display screen installed at the front end of the electric telescopic pole, and a detection head is installed at the lower end of the display screen, the detection head extending into the measuring cylinder.
[0009] Preferably, the lower bottom of the inner lifting cylinder is provided with a base support, and the inner bottom of the outer shell is provided with a plurality of lifting chambers arranged in a ring at intervals. A telescopic rod is installed in the lifting chamber, and the lower end of the telescopic rod is connected to the base support.
[0010] Preferably, a sealing limit ring is provided at the opening of the lifting cavity.
[0011] Preferably, an outer sealing magnetic ring is provided on the upper surface of the base, and an inner sealing magnetic ring is provided on the inner top of the outer shell.
[0012] Preferably, a protective cover is installed above the assembly frame, the electric telescopic rod is located inside the protective cover, and a transparent acrylic material is provided on the outer wall of the protective cover.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) In this utility model, the outer shell can be fixed above the polluted water source by the assembly frame. When it is necessary to monitor the polluted water source, the inner lifting cylinder is moved downward by the electric telescopic rod, so that the inner lifting cylinder is moved out into the outer shell and into the water. The water in the water enters the measuring cylinder through the sampling inlet and is monitored by the water quality monitoring device. After monitoring, the electric telescopic rod moves the inner lifting cylinder out of the water surface and the water is discharged from the sampling outlet. The inner lifting cylinder moves back into the outer shell to close. The sampling inlet and sampling outlet are equipped with mesh covers to filter impurities. The above structure can facilitate users to quickly collect water samples in water quality monitoring and discharge water. It can also prevent impurities from clogging the inside. When replacing and cleaning the mesh cover, it is only necessary to remove the inner lifting cylinder from the outer shell, which is convenient for users.
[0015] (2) In this utility model, when the electric telescopic rod drives the inner lifting cylinder to move, the base will move together, so that the telescopic rod is driven to extend and retract. At the same time, the telescopic rod has the effect of limiting the extension and retraction distance. When extending, the sealing limit ring restricts the telescopic rod to prevent it from leaving the lifting cavity. When retracting, the telescopic rod retracts into the lifting cavity. The outer sealing magnetic ring on the base is magnetically sealed with the bottom of the outer shell. The top of the inner lifting cylinder is magnetically sealed with the inner sealing magnetic ring, so that in the closed state, it is not easy for external impurities to enter the interior, thus improving safety.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Please see Figure 1 , Figure 3 , Figure 4This utility model provides an embodiment of an online water quality monitoring and sampling device for pollution sources, comprising: an outer shell 1, an assembly frame 107 mounted on top of the outer shell 1, an electric telescopic rod 4 mounted on top of the assembly frame 107, an inner lifting cylinder 2 mounted on the telescopic end of the electric telescopic rod 4, the inner lifting cylinder 2 being located inside the outer shell 1, sampling inlets 201 and sampling outlets 202 respectively opened on the outer walls of the front and rear ends of the inner lifting cylinder 2, the height of the sampling outlet 202 being lower than that of the sampling inlets 201, and because the sampling outlet 202 is lower than the inlets and close to the bottom of the cylinder, it can completely drain the water during drainage, reducing residue; a mesh cover 203 is provided on the outer walls of both the sampling inlets 201 and the sampling outlets 202, a measuring cylinder 6 is installed inside the inner lifting cylinder 2, and a water quality monitoring component 5 is also mounted on top of the assembly frame 107; specifically, the outer shell 1 can be fixed to the pollution source by the assembly frame 107. Above the polluted water source, when monitoring of the polluted water source is required, the electric telescopic rod 4 drives the inner lifting cylinder 2 downward, moving the inner lifting cylinder 2 out into the outer shell 1 and into the water. The water in the water enters the measuring cylinder 6 through the sampling inlet 201 and is monitored by the water quality monitoring device 5. After monitoring, the electric telescopic rod 4 drives the inner lifting cylinder 2 out of the water surface, and the water is discharged from the sampling outlet 202. The inner lifting cylinder 2 then moves back into the outer shell 1 and closes. The sampling inlet 201 and the sampling outlet 202 are equipped with a mesh cover 203 to filter impurities. The above structure facilitates the user to quickly collect water samples for water quality monitoring and discharges the water. It also prevents impurities from clogging the interior. When replacing or cleaning the mesh cover 203, it is only necessary to remove the inner lifting cylinder 2 from the outer shell 1, which is convenient for the user.
[0024] like Figure 4 As shown, during the sampling process described above, the front end of the measuring cylinder 6 is equipped with an inlet channel 601 connected to the sampling inlet 201, and the rear end of the measuring cylinder 6 is equipped with a drain valve 602 connected to the sampling outlet 202. Water entering the sampling inlet 201 enters the measuring cylinder 6 through the inlet channel 601. The drain valve 602 is used to control the opening and closing state of the pipeline. When it is open, the water can flow through the pipeline to the sampling outlet 202, thus draining the water. When it is closed, the water is confined within the measuring cylinder 6, facilitating sampling and monitoring of the water within the measuring cylinder 6.
[0025] like Figure 4 As shown, during the above sampling process, the water quality monitoring device 5 includes a display screen 502 installed at the front end of the electric telescopic pole 4. A detection head 501 is installed at the lower end of the display screen 502. The detection head 501 extends into the measuring cylinder 6. The water quality monitoring device 5 adopts the RS485 series from Shandong Renke Measurement and Control Co., Ltd., and is used to monitor water quality for different needs.
[0026] Please see Figure 1 , Figure 5 The bottom of the inner lifting cylinder 2 is provided with a base support 103. Multiple lifting chambers 101 are arranged in a ring at intervals on the bottom of the outer shell 1. A telescopic rod 102 is installed in the lifting chamber 101. A sealing limit ring 106 is provided at the opening of the lifting chamber 101. The lower end of the telescopic rod 102 is connected to the base support 103. An outer sealing magnetic ring 104 is provided on the upper surface of the base support 103. An inner sealing magnetic ring 105 is provided on the inner top of the outer shell 1.
[0027] When the electric telescopic rod 4 moves the inner lifting cylinder 2, it causes the base 103 to move as well, causing the telescopic rod 102 to extend and retract. At the same time, the telescopic rod 102 limits the extension and retraction distance. When extending, the sealing limit ring 106 restricts the telescopic rod 102 to prevent it from leaving the lifting cavity 101. When retracting, the telescopic rod 102 retracts into the lifting cavity 101. The outer sealing magnetic ring 104 on the base 103 magnetically seals with the bottom of the outer shell 1, and the top of the inner lifting cylinder 2 magnetically seals with the inner sealing magnetic ring 105. This makes it difficult for external impurities to enter the interior when closed, thus improving safety.
[0028] Please see Figure 2 A protective cover 3 is installed above the assembly frame 107, and an electric telescopic rod 4 is located inside the protective cover 3. A transparent acrylic 301 is provided on the outer wall of the protective cover 3.
[0029] The protective cover 3 is used to protect the internal electric telescopic rod 4 and water quality monitoring component 5. The transparent acrylic 301 allows users to easily observe the internal parts and the display screen 502.
[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
