Description

Technical Field

[0001] This utility model relates to the field of sewage sampling technology, and in particular to a sewage pipe network water quality sampling device. Background Technology

[0002] As an important component of urban infrastructure, the water quality monitoring of sewage pipe networks is crucial for environmental protection, water resource management, and public health safety. Accurate and efficient water quality sampling of sewage pipe networks is a prerequisite for obtaining reliable water quality data and plays a decisive role in formulating scientific and reasonable sewage treatment strategies. Based on water quality monitoring, sewage samples are taken and tested from within the sewage pipe network.

[0003] Currently, when sampling sewage pipe networks, manual sampling is generally used. However, this method is inefficient due to the need for timed and intermittent sampling. Automated sampling equipment has since been developed. This equipment directly stores the timed samples in storage bottles. Since water quality data testing involves a large amount of data, such as suspended solids and dissolved solids, the sampled sewage needs to be filtered for dissolved solids, while suspended solids do not require filtration. Therefore, the sampled sewage needs to be shaken before separation and then filtered again, which is inefficient and may affect the sampling efficiency and subsequent testing efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a sewage network water quality sampling device that can overcome or at least partially solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wastewater network water quality sampling device includes: a sampling bucket; a top cover threadedly and sealed to the upper side of the sampling bucket; multiple hanging buckles circumferentially fixed to the top cover; a fixing plate fixedly disposed inside the sampling bucket, and the fixing plate is provided with multiple mounting sleeves; multiple storage bottles disposed inside the mounting sleeves, each storage bottle having a first cavity, a second cavity, a third cavity, and a fourth cavity; and a first partition fixedly disposed inside the storage bottles, with one end of the first partition disposed between the first cavity and the second cavity, and the other end of the first partition disposed between the first cavity and the second cavity. Between the third and fourth cavities; a first connecting port is disposed on the first partition, and the first connecting port is used to connect the third and fourth cavities; a second partition is fixedly disposed between the second and fourth cavities, and the second partition is provided with a second connecting port; a filter assembly is disposed between the first and third cavities; a sampling assembly for sampling is disposed inside the sampling bucket, and the sampling assembly is used to periodically supply samples to the fourth cavity inside the storage bottle; and water outlets are symmetrically disposed on both sides of the storage bottle, and the ends of the water outlets are sealed with sealing plugs.

[0007] To facilitate wastewater sampling, the sampling assembly further includes a sampling tube fixedly installed inside a sampling bucket. The lower end of the sampling tube has an inlet. A piston plate is slidably connected inside the sampling tube. An electric telescopic rod is fixedly connected to the lower end of the fixed plate. The output end of the electric telescopic rod is fixedly connected to the piston plate. An energy storage box and a controller are fixedly connected to the upper side of the fixed plate. A connecting assembly is provided between the sampling tube and the storage bottle.

[0008] Preferably, the connecting assembly includes a drain pipe fixedly mounted on the sampling tube, one end of the drain pipe is provided with a connector, and a solenoid valve is provided inside the drain pipe. The upper end of the storage bottle is rotatably sealed with an upper sealing cap, and a water inlet communicating with the fourth cavity is fixedly connected to the upper sealing cap. The water inlet is threadedly connected to the connector.

[0009] To facilitate wastewater filtration, the filter assembly further includes a mesh plate fixedly disposed between the first chamber and the third chamber, with a filter element disposed on the upper side of the mesh plate.

[0010] To facilitate the replacement of the filter element, a filter frame is further provided on the upper side of the mesh plate, and the filter element is mounted on the filter frame.

[0011] To facilitate cleaning of the storage bottle, a lower sealing cap is further threaded onto the lower end of the storage bottle.

[0012] Compared with the prior art, this utility model provides a sewage pipe network water quality sampling device, which has the following beneficial effects:

[0013] 1. This sewage network water quality sampling equipment uses an electric telescopic rod to drive a piston plate upward to extract sewage. Then, a controller opens a solenoid valve in one of the drain pipes, and the electric telescopic rod again drives the piston plate downward, allowing sewage to enter the drain pipe. Finally, the sewage enters the fourth chamber. Some of the sewage in the fourth chamber is stored in the second chamber through a second connecting port, and the pressure in the fourth chamber gradually increases. When the sewage in the second chamber reaches a certain level, some of the sewage in the fourth chamber enters the third chamber. The pressure in the third chamber gradually increases, and the sewage in the third chamber is filtered before entering the first chamber for storage. This allows for the storage of both filtered and unfiltered samples of sewage, facilitating subsequent testing and effectively improving sampling and testing efficiency.

[0014] 2. The wastewater network water quality sampling equipment has a lower sealing cap at the bottom of the storage bottle, which facilitates cleaning of the storage bottle and prevents it from affecting the next sampling.

[0015] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model can store both filtered and unfiltered samples of sewage, facilitating subsequent testing and thus effectively improving sampling and testing efficiency.

[0021] 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.

[0022] Example 1: Refer to Figures 1-4 A wastewater network water quality sampling device includes: a sampling bucket 1, and a top cover 101 threadedly sealed to the upper side of the sampling bucket 1; multiple hanging buckles 102 circumferentially fixed on the top cover 101; a fixing plate 103 fixedly disposed inside the sampling bucket 1, and the fixing plate 103 is provided with multiple mounting sleeves 104; multiple storage bottles 3 disposed inside the mounting sleeves 104, and the storage bottles 3 are provided with a first cavity 301, a second cavity 302, a third cavity 303 and a fourth cavity 304; a first partition 305 fixedly disposed inside the storage bottles 3, with one end of the first partition 305 disposed between the first cavity 301 and the second cavity 302, and the other end of the first partition 305 disposed between the first cavity 301 and the second cavity 302. Between the third cavity 303 and the fourth cavity 304; a first connecting port 306 is disposed on the first partition 305, and the first connecting port 306 is used to connect the third cavity 303 and the fourth cavity 304; a second partition 307 is fixedly disposed between the second cavity 302 and the fourth cavity 304, and the second partition 307 is provided with a second connecting port 308; a filter assembly is disposed between the first cavity 301 and the third cavity 303; a sampling assembly for sampling is disposed in the sampling bucket 1, and the sampling assembly is used to supply samples to the fourth cavity 304 in the storage bottle 3 at regular intervals; a water outlet 315 is symmetrically disposed on both sides of the storage bottle 3, and the end of the water outlet 315 is sealed with a sealing plug 316.

[0023] The sampling assembly includes a sampling tube 2 fixedly installed inside the sampling barrel 1. The lower end of the sampling tube 2 is provided with a water inlet 203. A piston plate 202 is slidably connected inside the sampling tube 2. An electric telescopic rod 201 is fixedly connected to the lower end of the fixed plate 103. The output end of the electric telescopic rod 201 is fixedly connected to the piston plate 202. An energy storage box 105 and a controller 106 are fixedly connected to the upper side of the fixed plate 103. A connecting assembly is provided between the sampling tube 2 and the storage bottle 3.

[0024] The connecting assembly includes a drain pipe 204 fixedly mounted on the sampling tube 2. One end of the drain pipe 204 is provided with a connector 206, and a solenoid valve 205 is provided inside the drain pipe 204. The upper end of the storage bottle 3 is rotatably sealed with an upper sealing cap 312. An inlet 313 communicating with the fourth cavity 304 is fixedly connected to the upper sealing cap 312. The inlet 313 is threadedly connected to the connector 206.

[0025] The filter assembly includes a mesh plate 309 fixedly disposed between the first cavity 301 and the third cavity 303, and a filter element 311 is disposed on the upper side of the mesh plate 309.

[0026] Among them, the filter element 311 may be made of filter materials such as filter membranes and filter paper, and the selection shall be made according to the actual situation.

[0027] When sampling water quality in the sewage pipe network, the manhole cover is opened, and the entire sampling bucket 1 is placed in the sampling area. It is connected to the hook 102 by a rope. The sampling tube 2 is fixed inside the sampling bucket 1, and the inlet 203 at its lower end is responsible for collecting sewage. The piston plate 202 slides in a sealed manner inside the sampling tube 2. The output end of the electric telescopic rod 201 at the lower end of the fixed plate 103 is fixedly connected to the piston plate 202. After the electric telescopic rod 201 is started, it drives the piston plate 202 to move up and down inside the sampling tube 2, realizing the extraction and pushing of sewage. The controller 106 precisely controls the working time, stroke and other parameters of the electric telescopic rod 201 to achieve the purpose of timed sampling.

[0028] During the first sampling, the electric telescopic rod 201 drives the piston plate 202 to move upward to extract sewage. Then, the controller 106 controls the solenoid valve 205 in one of the drain pipes 204 to open, and then the electric telescopic rod 201 drives the piston plate 202 to move downward, allowing the sewage to enter the drain pipe 204. Finally, the sewage enters the fourth chamber 304 through the drain pipe 204. At this time, some of the sewage entering the fourth chamber 304 enters the second chamber 302 through the second connecting port 308 for storage, and the pressure in the fourth chamber 304 gradually increases. When the sewage in the second chamber 302 has been filled to a certain extent, some of the sewage in the fourth chamber 304 enters the third chamber 303. At this time, the pressure in the third chamber 303 gradually increases, and the sewage in the third chamber 303 is filtered by the filter element 311 and then enters the first chamber 301 for storage. This allows for the storage of both filtered and unfiltered sewage samples, facilitating subsequent testing and effectively improving the sampling and testing efficiency.

[0029] After a certain period of time, the controller 106 controls the solenoid valve 205 in this drain pipe 204 to close, and then controls the solenoid valve 205 in the next drain pipe 204 to open, thereby achieving the purpose of timed sampling.

[0030] In practice, staff do not need to stand next to the wellhead for extended periods, effectively reducing safety hazards.

[0031] It should be noted that one-way valves are installed in the drain pipe 204, the inlet 203, the first connecting port 306, and the second connecting port 308.

[0032] Example 2: Refer to Figures 1-4 A wastewater pipe network water quality sampling device is basically the same as that in Example 1. Further, a filter frame 310 is slidably connected to the upper side of the mesh plate 309, and a filter element 311 is disposed on the filter frame 310.

[0033] The lower end of the storage bottle 3 is threaded with a lower sealing cap 314.

[0034] By placing the filter element 311 on the filter frame 310, it is easy to replace or clean the filter element 311.

[0035] Furthermore, the lower sealing cap 314 provided at the bottom of the storage bottle 3 facilitates cleaning of the storage bottle 3, thereby preventing any impact on the next sampling.

[0036] 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.
