Description

Technical Field

[0001] This utility model relates to the field of ammonia nitrogen detection technology, and in particular to an online ammonia nitrogen detection device. Background Technology

[0002] Online ammonia nitrogen detection is a technology for real-time monitoring of ammonia nitrogen content in water bodies. It is widely used in wastewater treatment, environmental monitoring, industrial emission control, and aquaculture. Excessive ammonia nitrogen can lead to eutrophication, fish poisoning, and even threaten human health. Online detection can enable real-time monitoring of ammonia nitrogen concentration, helping to respond quickly to pollution incidents and ensure water quality safety.

[0003] For example, patent application number 201921813063.3 published on the China Patent Network, entitled "An Online Ammonia Nitrogen Detection Device," includes a first detection chamber, a second detection chamber, and a third detection chamber arranged from left to right. Each of the three chambers has a tube with a closed upper end, and an ammonia-sensitive electrode is installed inside the tube. A hydrophobic semi-permeable membrane is sealed and fixedly connected to the lower end of the tube. Multiple ammonia-sensitive electrodes are connected to a processor. A water sample chamber is located to the left of the first detection chamber, and a waste liquid chamber is located to the right of the third detection chamber. A booster pump is located to the left of the water sample chamber, and the output end of the booster pump is connected to the lower end of the water sample chamber via a pipe. This invention can determine the ammonia nitrogen content in the first, second, and third detection chambers from the measured potential, transmit the data to the processor, and obtain the average value. By detecting multiple water samples and calculating the average value, the measurement accuracy is improved.

[0004] However, existing ammonia nitrogen detection devices store reagent bottles directly inside the equipment, resulting in a cumbersome design for replacement. Each time reagents are replaced, the detection process must be paused, affecting continuous monitoring capabilities. Moreover, the reagents are mostly corrosive or toxic substances, and direct contact may endanger the health of operators. Utility Model Content

[0005] The purpose of this invention is to solve the problem of inconvenient reagent replacement in the prior art, and to propose an online ammonia nitrogen detection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An online ammonia nitrogen detection device includes a body, a support frame slidably connected inside the body, the support frame being able to move horizontally to the outside of the body, reagent bottles being provided on both sides of the top of the support frame, and an extraction tube being connected to the top of the inner wall of the body, the extraction tube being able to be inserted into the inside of the reagent bottle on the side away from the body to extract the reagent.

[0008] As a preferred technical solution of this application, guide rails are fixedly connected to both sides of the bottom of the support frame and both sides of the bottom of the inner wall of the machine body. The guide rails are interlocked and slide against each other.

[0009] As a preferred technical solution of this application, connecting blocks are fixedly connected to both sides of the top of the support frame, and a shaft is movably connected to the inner side of the connecting block through a bearing. A lifting frame located inside the support frame is fixedly connected to both sides of the surface of the shaft. The reagent bottle is placed on the surface of the lifting frame, and the lifting frame can carry the reagent bottle and swing and tilt around the shaft as the axis.

[0010] As a preferred technical solution of this application, both ends of the shaft pass through the connecting block and extend to the outside of the connecting block. Both ends of the shaft are fixedly connected to a force-bearing rod located outside the connecting block. A traction rope is fixedly connected to the back of the force-bearing rod. The side of the traction rope away from the force-bearing rod is fixedly connected to the rear side of the inner wall of the machine body. The traction rope is elastic.

[0011] As a preferred technical solution of this application, a frame is fixedly connected to the top of the bearing frame, and a spring plate is fixedly connected to the back of the force-bearing rod. The side of the spring plate away from the force-bearing rod is in contact with the front of the frame, and the spring plate is elastic.

[0012] As a preferred technical solution of this application, sleeves are fixedly connected to both sides of the top of the frame. The sleeves are fitted onto the surface of the extraction tube and are slidably connected to the extraction tube. The sleeves are L-shaped and have an arc transition at the bend.

[0013] As a preferred technical solution of this application, both sides of the shaft surface are fitted with rubber sleeves located inside the support frame, and the outer surface of the rubber sleeves is in contact with the front of the reagent bottle.

[0014] As a preferred technical solution of this application, guide grooves are provided on both the left and right sides of the body, and a shift fork is fixedly connected to the outer side of the force rod. The side of the shift fork away from the force rod can be inserted into the interior of the guide groove and slidably connected to the guide groove when swinging and resetting.

[0015] As a preferred technical solution of this application, movable blocks are fixedly connected to both sides of the back of the lifting frame, and a clamping plate is movably connected to the inner side of the movable block through a pin. The side of the clamping plate away from the movable block extends to the back of the reagent bottle and can contact the surface of the reagent bottle after swinging.

[0016] As a preferred technical solution of this application, a support plate is fixedly connected to the side of the clamping plate near the movable block, and the side of the support plate away from the clamping plate contacts the bottom of the inner wall of the machine body. When the support plate swings back and forth with the lifting frame, it can be squeezed by the machine body and carry the clamping plate to swing around the pin shaft.

[0017] Compared with the prior art, the present invention provides an online ammonia nitrogen detection device, which has the following beneficial effects:

[0018] 1. This online ammonia nitrogen detection device features a horizontally sliding support frame design that allows the reagent bottle to be moved entirely out of the device body. The reagent bottle can be replaced directly without disassembling the device, making operation convenient and avoiding reagent contamination. The extraction tube automatically detaches from or inserts into the reagent bottle as the support frame moves, simplifying the pipeline connection process.

[0019] 2. This online ammonia nitrogen detection device ensures the stability of the carrier frame's movement trajectory through an interlocking sliding structure of guide rails, preventing deviation or jamming; the symmetrical layout of the double guide rails enhances the load-bearing capacity of the carrier frame and prevents reagent bottles from tipping over due to vibration.

[0020] 3. This online ammonia nitrogen detection device achieves the tilting function of the reagent bottle through the linkage design of the shaft and the support frame. When the support frame is pulled out, the reagent bottle can automatically tilt at a certain angle, making it easier for users to observe the liquid level or take out the empty bottle, reducing the difficulty of operation.

[0021] 4. This online ammonia nitrogen detection device uses the elasticity of the traction rope to provide the reset driving force. When the support frame is pushed back to the machine body, it automatically drives the shaft to rotate so that the lifting frame returns to a horizontal state, reducing manual adjustment steps and improving reset efficiency.

[0022] 5. This online ammonia nitrogen detection device uses the elastic contact between the spring plate and the frame to buffer the impact force when the load-bearing frame moves, thus preventing damage to the shaft and support frame due to rigid collision; at the same time, the auxiliary traction rope controls the reset speed to ensure smooth operation.

[0023] 6. This online ammonia nitrogen detection device uses an L-shaped sleeve to flexibly guide the extraction tube, preventing the extraction tube from twisting or bending when the support frame slides; the arc transition design reduces frictional wear between the extraction tube and the sleeve, extending its service life.

[0024] 7. This online ammonia nitrogen detection device increases the friction between the reagent bottle and the support frame by using a rubber sleeve, preventing the reagent bottle from sliding or falling off during tilting or moving, while also avoiding scratches on the bottle surface by hard materials.

[0025] 8. This online ammonia nitrogen detection device limits the swing range of the shaft through the cooperation of the shift fork and the guide groove, ensuring that the lifting frame is accurately aligned with the initial position when resetting; the sliding connection reduces the resetting resistance and improves the reliability of the operation.

[0026] 9. This online ammonia nitrogen detection device uses a clamping plate to link the movable block with the lifting frame, automatically clamping the reagent bottle when the support frame is reset, preventing the reagent bottle from shaking or shifting during the detection process, and ensuring the stability of the insertion depth of the extraction tube.

[0027] 10. This online ammonia nitrogen detection device uses the contact and compression between the support plate and the inner wall of the machine to trigger the swing of the clamping plate, thereby achieving mechanical automation of the clamping action. No additional drive mechanism is required, which reduces energy consumption and cost. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0036] Example 1:

[0037] Reference Figure 1-6An online ammonia nitrogen detection device includes a body 1, with a support frame 2 slidably connected inside the body 1. The support frame 2 can be horizontally moved to the outside of the body 1. Reagent bottles 3 are arranged on both sides of the top of the support frame 2. An extraction tube 4 is connected to the top of the inner wall of the body 1. The side of the extraction tube 4 away from the body 1 can be inserted into the reagent bottle 3 to extract the reagent. Through the horizontally sliding support frame 2 design, the reagent bottle 3 can be moved out of the body 1 as a whole, and the reagent bottle 3 can be directly replaced without disassembling the device. The operation is convenient and avoids reagent contamination. The extraction tube 4 automatically detaches from or inserts into the reagent bottle 3 as the support frame 2 moves, simplifying the pipeline connection process. The bottom sides of the support frame 2 and the bottom of the inner wall of the body 1 are also connected. Guide rails 5 are fixedly connected to both sides of the support frame 2. The guide rails 5 are interlocked and slide against each other. Connecting blocks 6 are fixedly connected to both sides of the top of the support frame 2. A shaft 7 is movably connected to the inner side of the connecting block 6 through a bearing. Lifting frames 8 located inside the support frame 2 are fixedly connected to both sides of the surface of the shaft 7. The reagent bottle 3 is placed on the surface of the lifting frame 8. The lifting frame 8 can carry the reagent bottle 3 and swing and tilt around the shaft 7. Both ends of the shaft 7 pass through the connecting block 6 and extend to the outer side of the connecting block 6. Both ends of the shaft 7 are fixedly connected to the force rod 9 located outside the connecting block 6. A traction rope 10 is fixedly connected to the back of the force rod 9. The side of the traction rope 10 away from the force rod 9 is fixed to the rear side of the inner wall of the machine body 1. The traction rope 10 is elastic. A frame 11 is fixedly connected to the top of the bearing frame 2. A spring plate 12 is fixedly connected to the back of the force-bearing rod 9. The side of the spring plate 12 away from the force-bearing rod 9 contacts the front of the frame 11. The spring plate 12 is elastic. Sleeves 13 are fixedly connected to both sides of the top of the frame 11. The sleeves 13 are fitted onto the surface of the extraction tube 4 and are slidably connected to the extraction tube 4. The sleeves 13 are L-shaped with an arc transition at the bend. Rubber sleeves 14 located inside the lifting frame 8 are fitted onto both sides of the surface of the shaft rod 7. The outer surface of the rubber sleeves 14 contacts the front of the reagent bottle 3. Guide grooves 15 are opened on the left and right sides of the body 1. A spring plate 12 is fixedly connected to the outer side of the force-bearing rod 9. The fork 16, on the side away from the force rod 9, can be inserted into the guide groove 15 and slidably connected to the guide groove 15 when swinging back. Movable blocks 17 are fixedly connected to both sides of the back of the lifting frame 8. The inner side of the movable block 17 is movably connected to the clamp 18 through the pin. The side of the clamp 18 away from the movable block 17 extends to the back of the reagent bottle 3 and can contact the surface of the reagent bottle 3 after swinging. The side of the clamp 18 near the movable block 17 is fixedly connected to the support plate 19. The side of the support plate 19 away from the clamp 18 contacts the bottom of the inner wall of the machine body 1. When the support plate 19 swings back and forth with the lifting frame 8, it can be squeezed by the machine body 1 and swing with the clamp 18 around the pin.

[0038] Specifically, during operation / use of this online ammonia nitrogen detection device: When it is necessary to replace reagent bottle 3, the user pulls out the support frame 2 horizontally. The guide rail 5 ensures that the support frame 2 slides smoothly out of the body 1, avoiding shaking. During the movement of the support frame 2 carrying the reagent bottle 3, the extraction tube 4 inserted into the surface of the reagent bottle 3 is restricted by the sleeve 13, causing it to slide inside the sleeve 13 and detach from the inside of the reagent bottle 3. As the support frame 2 moves outward, the traction rope 10 is stretched, and the elastic plate 12 is compressed and bent, storing elastic potential energy. After the support frame 2 is fully pulled out, the elastic recoil force of the traction rope 10 and the elastic force of the elastic plate 12 work together to make the force rod 9 drive the shaft 7 to rotate, and the lifting frame 8 swings and tilts around the shaft 7. At this time, the clamping plate 18 is released from the pressure of the support plate 19 detaching from the inner wall of the body 1, making it easier to remove the reagent bottle 3. The user removes the old bottle, then places the new reagent bottle 3 onto the tilted support frame 8 and pushes back the support frame 2. The traction rope 10 and the spring plate 12 gradually release their elasticity, and the auxiliary support frame 8 slowly returns to the horizontal position. When the support frame 2 is fully inserted into the machine body 1, the support plate 19 contacts the bottom of the inner wall of the machine body 1. Under pressure, the clamping plate 18 swings around the pin axis, clamping the back of the reagent bottle 3. At the same time, the sleeve 13 guides the extraction tube 4 to re-insert into the reagent bottle 3. After the device is started, the extraction tube 4 stably extracts the reagent from the clamped and fixed reagent bottle 3. The double fixation of the rubber sleeve 14 and the clamping plate 18 prevents the reagent bottle 3 from shifting during the detection process, ensuring the accuracy of the detection data.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
