Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a water quality sampler for a pH adjustment tank. Background Technology

[0002] When treating sewage or chemical waste, a pH adjustment tank is required. As a key structure in sewage treatment, the main function of the pH adjustment tank is to adjust the pH value of the sewage so that the subsequent treatment units can operate stably in a suitable acid-base environment. Therefore, when treating sewage or waste, it is necessary to sample and test the water quality in the tank, which requires the use of a water quality sampler.

[0003] A search revealed Chinese Patent Publication No. CN221445470U, which discloses a water sampler comprising a rotating sleeve; a collection cylinder rotatably connected inside the rotating sleeve; water inlets located inside both the rotating sleeve and the collection cylinder; a rotating rod fixedly connected to the top of the collection cylinder; and a rotating handle fixedly connected to the top of the rotating rod. This design, featuring a rotatable collection cylinder inside the rotating sleeve and water inlets on both the sleeve and the collection cylinder, and controlling the opening and closing of the water inlets by rotating the handle to rotate the rotating rod and collection cylinder, facilitates water sampling at different depths. It effectively solves the problem that, during the lifting of the container after sampling, the upper layer of water sample easily enters the sampler, affecting the water sample quality. However, in practical use, the device requires manual rotation of the handle to control the water inlet, which makes it difficult to control the sampler effectively in pH tanks, affecting the water sampling effect and making sampling difficult at greater tank depths. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a water quality sampler for pH adjustment tanks, aiming to improve the problem in the prior art that the sampler cannot be well controlled in the pH tank, which affects the water sampling effect and makes sampling difficult when the tank is deep.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a water quality sampler for a pH adjustment tank, comprising an outer shell, a sealing shell fixedly connected to the bottom wall of the outer shell, a servo motor fixedly connected to the inner wall of the sealing shell, the output end of the servo motor penetrating through the bottom wall of the outer shell and fixedly connected to a rotating disk, a rotating groove being formed at the bottom of the inner wall of the outer shell, the outer wall of the rotating disk being rotatably connected to the rotating groove, a fixed base being fixedly connected to the top wall of the rotating disk, a connecting shell being fixedly connected to the front side of the fixed base, two return springs being fixedly connected to the rear side of the inner wall of the connecting shell, a sealing plate being fixedly connected to the front end of the return springs, a collection shell communicating with the front side of the outer shell, a filter plate being fixedly installed on the inner wall of the collection shell, a cleaning disc being slidably connected to the inner wall of the outer shell, a top cover being provided on the top of the outer shell, and a locking mechanism being provided on the top of the outer wall of the outer shell.

[0006] The above technical solution enables the fixed seat to rotate under the rotation of the rotating disk, so that the sealing plate can be released from the sealing shell. The liquid in the pool can be collected by the sampler through the filter plate to achieve the purpose of selecting the sampling depth. Then, with the liquid entering, the cleaning disk can be moved upward to clean the inner wall of the sampler and avoid the situation where there are residual objects interfering with the detection.

[0007] As a further description of the above technical solution: The locking mechanism includes a fixed plate, the inner wall of which is disposed on the top of the outer wall of the outer shell. A threaded ring is fixedly connected to the inner wall of the fixed plate. A threaded groove is formed on the top of the outer wall of the outer shell. The inner wall of the fixed plate is threadedly connected to the top of the outer wall of the outer shell through the threaded groove. Locking plates are rotatably connected to the front and rear sides of the top wall of the fixed plate. Locking grooves are formed on the front and rear sides of the top wall of the top cover. The bottom of the locking plate engages with the locking groove. A bolt is threadedly connected to the top wall of the locking plate. The bottom end of the bolt is threadedly connected to the top of the top cover.

[0008] The above technical solution allows the fixed plate to be disassembled or installed from the outer casing by rotating the fixed plate, thus enabling the fixed plate to be disassembled and cleaned. The bolts can be rotated to release the locking plate, and the top cover can be unlocked by flipping the locking plate. The top cover and cleaning plate can be removed for cleaning and maintenance, thus facilitating the maintenance and cleaning of the sampler.

[0009] As a further description of the above technical solution: A sealing plate is fixedly connected to the bottom wall of the top cover, and the outside of the sealing plate engages with the top of the outer shell.

[0010] The above technical solution enables the top of the sampler to be sealed by the connection of the sealing plate.

[0011] As a further description of the above technical solution: The locking mechanism also includes two rubber rings, the inner walls of which are respectively fixedly connected to the middle of the corresponding bolts.

[0012] The above technical solution reduces rotational damage to the top of the locking plate caused by the bolts, thanks to the connection of the rubber ring.

[0013] As a further description of the above technical solution: A pull rod is rotatably connected to the outer wall of the fixed plate, and a connecting buckle is provided inside the pull rod.

[0014] The above technical solution makes it easy to connect the sampler by connecting the pull rod and the connecting buckle.

[0015] As a further description of the above technical solution: A transparent graduated tube is fixedly installed on the right side of the outer casing, and the outer wall of the transparent graduated tube is designed to be smooth.

[0016] The above technical solution enables the observation of the collected liquid volume through the connection of a transparent graduated tube.

[0017] As a further description of the above technical solution: Limiting rods are fixedly connected to the left and right sides of the top wall of the cleaning tray, and limiting grooves are opened on the left and right sides of the outer shell. One side of the limiting rod is slidably connected to the limiting groove.

[0018] The above technical solution improves the lifting stability of the cleaning disc by allowing the limit rod and the limit groove to slide together.

[0019] As a further description of the above technical solution: A counterweight ring is fixedly connected to the bottom of the outer wall of the shell, and the counterweight ring adopts an arc-shaped design.

[0020] The above technical solution increases the weight of the sampler by connecting the counterweight ring, making it easier to sink. This utility model has the following beneficial effects: 1. In this utility model, the rotation of the rotating disk causes the fixed seat to rotate, thereby releasing the sealing plate from the collection shell. This allows the liquid in the pool to pass through the filter plate and enter the sampler, achieving the purpose of selecting the sampling depth. Subsequently, with the liquid entering, the cleaning disk can move upward, thereby cleaning the inner wall of the sampler and avoiding interference from residual substances. Ultimately, this improves the accuracy and convenience of water sampling.

[0021] 2. In this utility model, by rotating the fixed plate, it can be disassembled or installed on the top of the outer wall of the outer shell, thereby completing the disassembly and cleaning of the fixed plate. By rotating the bolt, the fixing of the locking plate can be released. Then, by flipping the locking plate, the top cover can be released, and the top cover and cleaning plate can be removed for cleaning and maintenance, thus improving the maintenance efficiency of the sampler.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a pH adjustment tank water quality sampler, comprising a housing 1, a sealing shell 3 fixedly connected to the bottom wall of the housing 1, which protects a servo motor 4, and a servo motor 4 fixedly connected to the inner wall of the sealing shell 3. The output end of the servo motor 4 passes through the bottom wall of the housing 1 and is fixedly connected to a rotating disk 5. A rotating groove 6 is provided at the bottom of the inner wall of the housing 1, so that the rotating disk 5 can rotate under the drive of the servo motor 4, thereby driving the fixed base 7 to rotate synchronously. The outer wall of the rotating disk 5 is rotatably connected to the rotating groove 6, and the top wall of the rotating disk 5 is fixedly connected to the fixed base 7. A connecting shell 8 is fixedly connected to the front side of the fixed seat 7. Two return springs 9 are fixedly connected to the rear side of the inner wall of the connecting shell 8. Under the connection of the return springs 9, the sealing plate 10 can seal the collection shell 11 to prevent liquid from entering. The sealing plate 10 is fixedly connected to the front end of the return spring 9. The collection shell 11 is connected to the front side of the outer shell 1. A filter plate 12 is fixedly installed on the inner wall of the collection shell 11. A cleaning plate 13 is slidably connected to the inner wall of the outer shell 1. With the entry of liquid, the cleaning plate 13 is pushed up and down by the liquid. A top cover 19 is provided on the top of the outer shell 1. A locking mechanism 2 is provided on the top of the outer wall of the outer shell 1. Specifically, by connecting to an external control device, the servo motor 4 can be started, causing the rotating disk 5 to rotate inside the rotating groove 6. As the rotating disk 5 moves, the fixed seat 7 will correspondingly drive the sealing plate 10 to rotate. During the rotation, the sealing plate 10 will release the sealing state with the collection shell 11. At the same time, through the elastic force of the return spring 9, the sealing effect of the sealing plate 10 can be enhanced, ensuring the tightness of the sealing. As the sealing plate 10 continues to rotate, the liquid in the pool can be filtered through the filter plate 12 and then enter the interior of the sampler through the collection shell 11. By rotating the sealing plate 10, the sampling depth can be selected, thereby controlling the amount of liquid sampled. After the liquid enters the sampler, the cleaning plate 13 will move upward accordingly to clean the inner wall of the outer shell 1, effectively avoiding the interference of residues on the inner wall of the outer shell 1 on the sampling and detection, thereby improving the accuracy and convenience of water sampling.

The inner wall of the fixing plate 201 is located on the top of the outer wall of the outer casing 1. A threaded ring 202 is fixedly connected to the inner wall of the fixing plate 201, so that when the fixing plate 201 rotates, it can be disassembled or installed with the outer casing 1 through the threaded connection between the threaded ring 202 and the threaded groove 203. The top of the outer wall of the outer casing 1 is provided with a threaded groove 203, and the inner wall of the fixing plate 201 is threadedly connected to the top of the outer wall of the outer casing 1 through the threaded groove 203. Locking plates 204 are rotatably connected to the front and rear sides of the top wall of 01, so that when the locking plates 204 are flipped, they can be locked or separated from the top cover 19. Locking grooves 205 are provided on the front and rear sides of the top wall of the top cover 19. The bottom of the locking plate 204 is engaged with the locking groove 205. Bolts 206 are threadedly connected to the top wall of the locking plate 204. The connection of the bolts 206 can further improve the fixation of the top cover 19. The bottom end of the bolt 206 is threadedly connected to the top of the top cover 19. Specifically, by rotating the bolt 206, the locking plate 204 can be unlocked. Then, by flipping the locking plate 204, it is disengaged from the top part of the top cover 19, thereby releasing the locking state of the top cover 19. Subsequently, by rotating the fixing plate 201, it is separated from the top of the outer wall of the housing 1, completing the disassembly or installation operation. Then, the fixing plate 201 can be removed for cleaning. At the same time, the cleaning plate 13 can be taken out for cleaning and maintenance, which simplifies the maintenance process. Moreover, through regular cleaning and maintenance, the service life of the entire device is improved.

[0028] Reference Figure 1 , Figure 2 and Figure 3A transparent graduated tube 18 is fixedly installed on the right side of the outer shell 1, and the outer wall of the transparent graduated tube 18 is designed to be smooth. Limiting rods 14 are fixedly connected to the left and right sides of the top wall of the cleaning disc 13, and limiting grooves 15 are opened on the left and right sides of the outer shell 1. One side of the limiting rod 14 is slidably connected to the limiting groove 15. A counterweight ring 20 is fixedly connected to the bottom of the outer wall of the outer shell 1, and the counterweight ring 20 is designed to be arc-shaped. Specifically, the volume of the collected liquid can be observed through the transparent graduated tube 18, the sliding connection between the limiting rod 14 and the limiting groove 15 improves the stability of the cleaning disc 13 during displacement, and the counterweight ring 20 increases the weight of the sampler, thereby facilitating the sampling work.

[0029] Working principle: When in use, the servo motor 4 is started by the external control device, which makes the rotating disk 5 rotate inside the rotating groove 6. This causes the fixed seat 7 to drive the sealing plate 10 to rotate. Then, the sealing plate 10, which is fixed by the return spring 9, can release the seal with the collection shell 11. At the same time, the sealing effect of the sealing plate 10 can be improved by the connection of the return spring 9. Then, under the rotation of the sealing plate 10, the liquid in the pool can be filtered through the filter plate 12 and enter the interior of the sampler through the collection shell 11. The rotation of the sealing plate 10 can achieve the purpose of selecting the sampling depth. Then, under the liquid entering, the cleaning disk 13 can be moved upward, thereby cleaning the inner wall of the outer shell 1 and avoiding the situation where the residue interferes with the sampling and detection, thus improving the accuracy and convenience of water sampling. Furthermore, by rotating the bolt 206, the locking plate 204 can be released. Then, the locking plate 204 can be flipped to separate it from the top of the top cover 19, thereby releasing the top cover 19 from its lock. Subsequently, by rotating the fixing plate 201, it can be disassembled or installed from the top of the outer wall of the housing 1, thus enabling the fixing plate 201 to be disassembled and cleaned. The top cover 19 and the cleaning plate 13 can be removed for cleaning and maintenance, improving the service life of the device.
