[0002] Chemical wastewater testing is a crucial part of environmental monitoring, aiming to ensure that industrial wastewater discharges comply with national and local environmental protection standards. Traditional sampling methods for chemical wastewater testing primarily involve manual sampling, which typically involves directly extracting samples from wastewater discharge points or treatment ponds by hand.
[0003] However, traditional techniques have some problems: because the composition and concentration of wastewater vary with time and location, manual sampling often cannot fully reflect the overall situation of the wastewater, resulting in insufficient sample representativeness. Utility Model Content
[0004] To address the problems existing in the prior art, this utility model provides a safe sampling device for chemical wastewater testing, which solves the problem that manual sampling often cannot fully reflect the overall condition of wastewater because the composition and concentration of wastewater change with time and location.
[0005] This utility model discloses a safe sampling device for chemical wastewater testing, comprising a support frame and a placement cylinder rotatably mounted on the upper part of the support frame. The placement cylinder has several through-holes inside, and the bottom of the support frame movably seals the inside of the placement slots of the placement cylinder. A sampling tube is screwed into the placement slots of the placement cylinder. A sampling component is fixed to one side of the support frame. When the sampling component performs a sampling action, it drives the placement cylinder to rotate. A mounting base is fixedly connected to the lower part of the support frame. The mounting base is movably aligned with the several placement slots and cooperates with the sampling component to perform sampling switching and filling actions.
[0006] In a preferred embodiment of the present invention, the sampling assembly includes a fixing tube, which is fixed to one side of the support frame, and a piston rod is slidably installed inside the sampling tube.
[0007] In a preferred embodiment of this invention, the output end of the fixed tube is fixedly connected to a first transmission tube via a one-way valve, and the end of the first transmission tube away from the fixed tube is fixed to the lower part of the mounting base.
[0008] In a preferred embodiment of this invention, the input end of the fixed tube is fixedly connected to a second transmission tube via a check valve, and a sieve head is fixedly connected to the end of the second transmission tube away from the fixed tube.
[0009] As a preferred embodiment of this utility model, an electric actuator is fixedly connected to a support plate fixed on one side of the support frame, and the output end of the electric actuator is fixedly connected to the piston rod.
[0010] In a preferred embodiment of this invention, a toothed plate is fixedly connected to the side of the piston rod near the electric push rod, a gear is mounted on the upper part of the support frame via a one-way bearing, the gear meshes with the toothed plate, and a toothed ring is fixedly connected to the outside of the placement cylinder, the toothed ring meshes with the gear.
[0011] As a preferred embodiment of this utility model, the sampling tube includes a tube body with a thread on the upper part of the tube body. The tube body is screwed into the placement groove of the placement cylinder through the thread. A tube head is inserted and installed on the upper part of the tube body. A transmission component is fixedly installed on the top of the tube head and the bottom of the tube body, respectively.
[0012] In a preferred embodiment of this invention, the transmission component includes a fixed disk, which is fixed to the top of the tube head. A plug is slidably installed inside the fixed disk via a spring, and the plug has a transmission channel to the outside of the tube head.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] In this invention, sampling tubes are placed inside several placement cylinders during sampling. The placement grooves of the placement cylinders penetrate the main body of the placement cylinders and are sealed by the bottom of the support frame. At the same time, an mounting base is fixedly installed at the bottom of the support frame. The mounting base is used to communicate with one of the sampling grooves. Thus, when the sampling tube in one placement groove is filled, the placement cylinder can be rotated to switch sampling tubes. When the sampling component is used to pump water for chemical wastewater testing, the wastewater is poured into the sampling tube through the mounting base. After sampling is completed, the placement cylinder is driven to rotate.

[0022] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0023] The structure of this utility model will now be described in detail with reference to the accompanying drawings.
[0024] like Figures 1 to 4 As shown in the figure, the present invention provides a safe sampling device for chemical wastewater testing, including a support frame 2, and further including: a placement cylinder 3 rotatably installed on the upper part of the support frame 2, the placement cylinder 3 having several through placement slots inside, the bottom of the support frame 2 movably sealing the inside of the placement slots of the placement cylinder 3, and a sampling tube 4 screwed into the inside of the placement slots of the placement cylinder 3; a sampling component fixed on one side of the support frame 2, the sampling component driving the placement cylinder 3 to rotate when performing sampling action, and a mounting base 14 fixedly connected to the lower part of the support frame 2, the mounting base 14 being movably aligned with several placement slots and cooperating with the sampling component to perform sampling switching and filling actions.
[0025] The above-mentioned safe sampling device for chemical wastewater testing, when sampling, places sampling tubes 4 inside several placement cylinders 3, and the placement groove of the placement cylinder 3 penetrates the main body of the placement cylinder 3 and is blocked by the bottom of the support frame 2. At the same time, the bottom of the support frame 2 is fixedly installed with an installation seat 14, which is used to communicate with one of the sampling grooves. Then, when the sampling tube 4 in one placement groove is filled, the placement cylinder 3 can be rotated to switch the sampling tube 4.
[0026] Simultaneously, when the sampling component is used to pump water for chemical wastewater testing, the wastewater is poured into the sampling tube 4 through the mounting base 14. After sampling is completed, the placement cylinder 3 is driven to rotate. Thus, the user can control the action of the sampling component to achieve automated interval sampling, which solves the problems in the background technology. The support frame 2 can also be installed on a small boat for multi-point sampling.
[0027] In this embodiment, the sampling assembly includes a fixed tube 7, which is fixed to one side of the support frame 2. A piston rod 8 is slidably installed inside the sampling tube 4. The output end of the fixed tube 7 is fixedly connected to a first transmission tube 11 via a one-way valve. The end of the first transmission tube 11 away from the fixed tube 7 is fixed to the lower part of the mounting base 14. The input end of the fixed tube 7 is fixedly connected to a second transmission tube 12 via another one-way valve. The end of the second transmission tube 12 away from the fixed tube 7 is fixedly connected to a sieve head 13.
[0028] During wastewater collection, a fixed pipe 7 is fixed to one side of the support frame 2. A piston rod 8 is slidably installed inside the sampling pipe 4. The input end of the fixed pipe 7 is fixedly connected to a second transmission pipe 12 through a one-way valve. A sieve head 13 is fixedly connected to the end of the second transmission pipe 12 away from the fixed pipe 7. The sieve head 13 can be placed in the wastewater for screening and filtration to prevent debris from clogging the second transmission pipe 12. At this time, the wastewater enters the fixed pipe 7. When the piston rod 8 is pushed by the two one-way valves, the wastewater in the fixed pipe 7 is transferred to the sampling pipe 4 corresponding to the fixed seat.
[0029] In this embodiment, an electric actuator 6 is fixedly connected to a support plate 1 fixed to one side of the support frame 2, and a piston rod 8 is fixedly connected to the output end of the electric actuator 6. A toothed plate 9 is fixedly connected to the outside of the piston rod 8 near the electric actuator 6. A gear 10 is mounted on the upper part of the support frame 2 through a one-way bearing. The gear 10 meshes with the toothed plate 9. A toothed ring 5 is fixedly connected to the outside of the placement cylinder 3. The toothed ring 5 meshes with the gear 10.
[0030] To achieve the linkage between pumping and sampling tube 4, the user controls the electric push rod 6 to control the piston rod 8 to pump water. A toothed plate 9 is fixedly connected to the side of the piston rod 8 near the electric push rod 6. A gear 10 is installed on the upper part of the support frame 2 through a one-way bearing. This allows the gear 10 to rotate each time the piston rod 8 drives the toothed plate 9 to reset. Consequently, the toothed ring 5 is driven by the gear 10 to rotate the placement cylinder 3, thus achieving the purpose of switching sampling tube 4.
[0031] In this embodiment, the sampling tube 4 includes a tube body 401 with a thread 404 on its upper part. The tube body 401 is screwed into the placement groove of the placement cylinder 3 via the thread 404. A tube head 402 is inserted and installed on the upper part of the tube body 401. A transmission component 403 is fixedly installed on the top of the tube head 402 and the bottom of the tube body 401, respectively. The transmission component 403 includes a fixing plate 4031, which is fixed to the top of the tube head 402. A plug 4032 is slidably installed inside the fixing plate 4031 via a spring 4033. A transmission channel 4034 for the outside of the tube head 402 is opened inside the plug 4032.
[0032] When placing the sampling tube 4, the tube body 401 is threaded with a thread 404 on the upper part, and the tube body 401 is screwed into the placement groove of the placement cylinder 3 through the thread 404 to achieve placement.
[0033] To achieve automated filling, a transmission component 403 is fixedly installed at the top of the filling head 402 and the bottom of the pipe body 401. During filling, the water flow pushes the plug 4032 to overcome the tension of the spring 4033 and rises. At this time, the transmission channel is connected to the pipe body 401 to fill wastewater. At the same time, the plug 4032 of the filling head 402 is connected to the outside to perform an air venting action.
[0034] The working principle of this utility model:
[0035] During sampling, sampling tubes 4 are placed inside several placement cylinders 3, and the placement groove of the placement cylinder 3 passes through the main body of the placement cylinder 3 and is blocked by the bottom of the support frame 2. At the same time, an mounting seat 14 is fixedly installed at the bottom of the support frame 2. The mounting seat 14 is used to communicate with one of the sampling grooves. When the sampling tube 4 in one placement groove is filled, the placement cylinder 3 can be rotated to switch the sampling tube 4. At the same time, when the sampling component is used to pump water for chemical wastewater detection, the wastewater is poured into the sampling tube 4 through the mounting seat 14. After sampling is completed, the placement cylinder 3 is driven to rotate. Thus, the user can control the action of the sampling component to realize automated interval sampling, which solves the problems in the background technology. The support frame 2 can also be installed on a small boat for multi-point sampling.
