Description

Technical Field

[0001] The present invention relates to the technical field of wastewater detection, and in particular to a detection device for wastewater discharge generated by water conservancy construction. Background Art

[0002] Water conservancy construction, that is, water conservancy project construction, is a type of engineering construction, mainly involving the construction of hydraulic structures, such as reservoirs, dams, canals, hydropower stations, etc. As we all know, wastewater testing is mainly a general term for the detection of wastewater, sewage and aquatic organisms discharged by enterprises and factories during the production process. Process wastewater testing includes production wastewater and production sewage. According to the products and processing objects of industrial enterprises, it can be divided into papermaking wastewater, textile wastewater, leather making wastewater, pesticide wastewater, metallurgical wastewater, oil refining wastewater, etc.

[0003] At present, when sampling and testing process wastewater, most of the wastewater discharged during the production process is sampled by directly throwing a single sampling bottle into the wastewater pool. When sampling wastewater at different depths, the existing device ties a rope to the bottle mouth of a sampling bottle with a balloon at one end and gas inside, and then throws the sampling bottle into the wastewater to be sampled and tested for sampling. Before sampling, all the gas inside the sampling bottle is squeezed into the balloon, and then placed in the wastewater at a specified depth. When the water pressure at the depth to be sampled is greater than the air pressure inside the balloon, the water will automatically enter the sampling bottle, thereby realizing the sampling of wastewater at different depths. When sampling, the existing device can only realize single sampling and single depth sampling. If sampling at different depths or different positions is required, multiple throwing sampling is required. It is impossible to realize one-time sampling of wastewater at different depths in one throwing sampling process. The operation is more troublesome and the sampling efficiency is low. In addition, during the sampling process, the larger impurities that may exist in the wastewater can easily enter the sampling bottle directly, resulting in a higher impurity content in the water sample. Without filtering and cleaning the sampling end of the sampling bottle, it is easy to affect the representativeness and accuracy of the test results after sampling. In addition, during the casting process, the sampling bottle may break due to impact or improper operation, resulting in sample leakage or sampling failure; the casting sampling bottle may not accurately reach the predetermined sampling position, resulting in the sample taken not being able to truly reflect the situation of the entire material or water area. Summary of the invention

[0004] In view of the problems in the prior art that the sampling bottle is easy to break, cannot accurately reach the predetermined sampling position, needs to be repeated for many times, and impurities easily enter the sampling bottle, a detection device for wastewater discharge generated by water conservancy construction is proposed.

[0020] Beneficial effects of the present invention:

[0021] 1. By starting the driving motor, the driving motor rotates forward, driving the threaded rod to rotate forward, and through the limit assembly, the piston moves upward inside the collection tube, and the wastewater is pumped into the collection tube through the collection tube. When the piston moves to the top of the collection tube, the driving motor is controlled to reverse, driving the threaded rod to reverse, so that the piston moves downward inside the collection tube to squeeze the wastewater in the collection tube. By controlling the length of the rope, the position of the sampling box in the wastewater can be changed, and then different layers of wastewater in the wastewater are sampled, avoiding repeated sampling of wastewater and reducing sampling efficiency. Moreover, the designated sampling position can be accurately reached, which can truly reflect the water quality of the water area.

[0022] 2. The wastewater collected in the collection tube can be discharged through the discharge assembly. The slider slides inside the first movable chamber to compress the reset spring. Under the action of the reset spring, the slider slides close to or away from the reset spring inside the first movable chamber, thereby driving the telescopic tube assembly to move up and down, so that the collecting component can accurately collect the wastewater when collecting the wastewater, and can also collect the wastewater repeatedly for multiple times.

[0023] 3. When the piston moves upward in the collection tube, the gas in the collection tube will enter the collection tube, causing the cover to rotate, forming a passage in the collection tube, stretching the pull rope, driving the connecting ring to move, sealing the vent, allowing wastewater to enter the collection tube and the collection tube. After the collection tube is filled with wastewater, under the action of gravity, the cover rotates downward to open the vent, allowing the gas in the sampling box to enter the collection tube. Under the action of gravity and air pressure, the wastewater in the collection tube flows back to the wastewater pool, avoiding mixing between each layer of collected wastewater.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0038] Example 1, reference Figure 1-Figure 5 , which is the first embodiment of the present invention, provides a detection device for wastewater discharge generated by water conservancy construction, including a sampling box 1, a handle frame 11 rotatably connected to the sampling box 1, and a lifting ring 12 fixedly connected to the handle frame 11, and also includes a sampling unit installed in the sampling box 1; the sampling unit includes a collecting component installed on the inner wall of the sampling box 1, and a collecting component installed at the inner bottom of the sampling box 1, the collecting component includes a collecting component 2 installed on the inner wall of the sampling box 1, a limiting component 3 installed on one side of the collecting component 2, a discharging component 4 installed at the bottom of the collecting component 2, and A telescopic tube assembly 5 is installed on one side of the discharge assembly 4; the collection assembly 2 includes a collection tube 21 fixedly connected to the inner wall of the sampling box 1, a threaded rod 24 rotatably connected to the inner side of the collection tube 21, a piston 25 threadedly connected to the outer side of the threaded rod 24, the piston 25 is slidably connected to the inner side of the collection tube 21, a driving motor 22 fixedly connected to the bottom of the collection tube 21, a collection tube 23 fixedly connected to one side of the bottom of the collection tube 21, a one-way feed valve fixedly connected to the inner side of the collection tube 23, and a filter cover 26 fixedly connected to the bottom of the sampling box 1, and the collection tube 23 passes through the bottom of the sampling box 1 and extends to the inner side of the filter cover 26.

[0039] Specifically, when in use, the rope is fixed on the lifting ring 12, the sampling box 1 is lifted by the handle 11, and slowly placed in the wastewater. Under the action of the top cover on the top of the sampling box 1, the inside of the sampling box 1 is kept sealed. When the sampling box 1 moves to the specified water level, wastewater sampling is performed through the sampling unit, the wastewater is collected through the collecting component, and the collected wastewater is collected through the collecting component. The driving motor 22 is started to rotate forward, driving the threaded rod 24 to rotate forward, and the piston 25 is moved upward on the inner side of the collecting tube 21 through the limiting component 3, and the wastewater is pumped into the collecting tube 21 through the collecting tube 23, and the collected wastewater is filtered through the filter cover 26 to prevent excessive impurities from entering the collecting tube 23 and affecting the wastewater. The detection result of water is that when the piston 25 moves to the top of the collection tube 21, the driving motor 22 is controlled to reverse, driving the threaded rod 24 to reverse, so that the piston 25 moves downward inside the collection tube 21, and squeezes the wastewater in the collection tube 21. Under the action of the one-way feed valve, the wastewater will not flow out of the collection tube 23, so that the wastewater is discharged from the discharge assembly 4, enters the telescopic tube assembly 5, and enters the collection component to complete the sampling of the wastewater. By controlling the length of the rope, the position of the sampling box 1 in the wastewater can be changed, and then the wastewater in different layers of the wastewater can be sampled, avoiding repeated sampling of the wastewater and reducing the sampling efficiency. Moreover, it can accurately reach the designated sampling position, which can truly reflect the water quality of the water area.

[0040] Reference Figure 3 and Figure 4 The limiting assembly 3 includes a baffle 32 slidably connected to one side of the collecting tube 21, a first through hole 31 opened on the collecting tube 21 and located on one side of the baffle 32, a second through hole 35 opened on the collecting tube 21 and located on the other side of the baffle 32, a limiting block 34 slidably connected to the inner side of the first through hole 31, one side of the limiting block 34 is fixedly connected to the piston 25, and the other side of the limiting block 34 is fixedly connected to the baffle 32, and an L-shaped rod 33 slidably connected to the inner side of the second through hole 35, and the L-shaped rod 33 is fixedly connected to the baffle 32.

[0041] Specifically, when the piston 25 moves in the collection tube 21, the limit block 34 slides on the inner side of the first through hole 31, thereby limiting the circumferential rotation of the piston 25, driving the baffle 32 to slide, and driving the L-shaped rod 33 to slide in the second through hole 35. Under the action of the baffle 32, the first through hole 31 and the second through hole 35 are sealed, so that when the limit block 34 slides in the first through hole 31 and the L-shaped rod 33 slides in the second through hole 35, the waste water in the collection tube 21 will not flow out from the first through hole 31 and the second through hole 35, thereby ensuring the smooth sampling and making the piston 25 move more stably in the collection tube 21.

[0042] Reference Figure 5The discharge assembly 4 includes a first active cavity 42 opened at the bottom of the collecting tube 21, a slider 41 slidably connected to the inner side of the first active cavity 42, and a return spring 43 fixedly connected between the top of the slider 41 and the inner wall of the top of the first active cavity 42.

[0043] Specifically, the wastewater collected in the collecting tube 21 can be discharged through the discharge assembly 4, and the slider 41 slides inside the first active cavity 42 to compress the reset spring 43. Under the action of the reset spring 43, the slider 41 slides close to the reset spring 43 or slides away from the reset spring 43 inside the first active cavity 42, thereby driving the telescopic tube assembly 5 to move up and down, so that the collecting component can accurately collect the wastewater when collecting the wastewater, and can also collect the wastewater repeatedly for multiple times.

[0044] Reference Figure 5 and Figure 6 The telescopic tube assembly 5 includes a connecting tube 51 fixedly connected to the slider 41 and connected to the inner side of the collecting tube 21, a one-way discharge valve fixedly connected to the inner side of the connecting tube 51, a plug 53 slidably connected to the end of the connecting tube 51 away from the slider 41, a tension spring 52 sleeved on the connecting tube 51, one end of the tension spring 52 is fixedly connected to the connecting tube 51, the other end of the tension spring 52 is fixedly connected to the plug 53, an L-shaped tube 54 fixedly connected to the end of the plug 53 away from the connecting tube 51, and a discharge hole 55 is opened on the L-shaped tube 54.

[0045] Specifically, the slider 41 slides in the first active cavity 42, driving the connecting tube 51, the insert tube 53 and the L-shaped tube 54 to move up and down, so that the L-shaped tube 54 can be accurately aligned with the collecting component, and the waste water in the collecting tube 21 will enter the connecting tube 51 through the insert tube 53, enter the L-shaped tube 54, and be discharged from the discharge hole 55, and the insert tube 53 can slide on the connecting tube 51 to compress the tension spring 52. Under the action of the tension spring 52, the insert tube 53 moves on the connecting tube 51 close to the tension spring 52 or moves away from the tension spring 52, thereby driving the L-shaped tube 54 to move close to the collecting tube 21 or move away from the collecting tube 21, thereby facilitating the collection component to be placed in the sampling box 1 or taken out from the sampling box 1, so that the collected samples can be used.

[0046] Example 2, reference Figure 7, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the collection component also includes a cleaning component 6 installed on the filter cover 26, and an exhaust component 7 installed in the collection pipe 23; the cleaning component 6 includes a turbine 65 rotatably connected to the inner side of the bottom of the collection pipe 23, a connecting shaft 64 fixedly connected to the bottom of the turbine 65, the bottom of the connecting shaft 64 passes through the filter cover 26 and is rotatably connected to the filter cover 26, a bottom rod 62 fixedly connected to the bottom of the connecting shaft 64, a fixing seat 61 fixedly connected to both ends of the bottom rod 62, and a cleaning cotton 63 fixedly connected to the fixing seat 61, and the cleaning cotton 63 is in contact with the outer wall of the filter cover 26.

[0047] Specifically, the wastewater entering the collection tube 23 is filtered through the filter cover 26, and excess impurities can be filtered out to prevent excessive impurities from entering the collection tube 23 and being collected by the collection component, thereby affecting the detection results. After use, impurities will be attached to the outer surface of the filter cover 26. If it is not cleaned, the filter holes of the filter cover 26 will be easily blocked. When the collection tube 23 extracts wastewater, the water flow drives the turbine 65 to rotate, drives the connecting shaft 64 to rotate, drives the bottom rod 62 to rotate, drives the fixing seat 61 to rotate, and drives the cleaning cotton 63 to rotate, so as to clean the outer surface of the filter cover 26. When the collection tube 23 extracts wastewater, the turbine 65 rotates, causing the cleaning cotton 63 to rotate on the surface of the filter cover 26 to clean impurities.

[0048] Reference Figure 8 The exhaust assembly 7 includes a cover plate 71 hinged on the top of the inner side of the collection tube 23, a second active chamber 75 provided on the inner side of the collection tube 23 and located at the bottom of the cover plate 71, a vent hole 78 provided on the collection tube 23 to connect the second active chamber 75 with the outside, a plug rod 77 inserted into the inner side of the vent hole 78, a sealing round block 76 fixedly connected to one end of the plug rod 77, a connecting ring 73 fixedly connected to the other end of the plug rod 77, a connecting spring 74 sleeved on the plug rod 77, one end of the connecting spring 74 fixedly connected to the connecting ring 73, the other end of the connecting spring 74 fixedly connected to the inner wall of the second active chamber 75, and a pull rope 72 fixedly connected between the cover plate 71 and the connecting ring 73.

[0049] Specifically, after the collection tube 23 has collected the wastewater, there is always a certain layer of wastewater in the collection tube 23. In this way, the wastewater collected from multiple layers at the same time will be mixed together, so the collected wastewater is impure. Through the exhaust component 7, the wastewater collected by the collection tube 23 can flow back to the wastewater pool, so that the collection tube 23 will not be mixed with the wastewater of the upper layer, and the collected wastewater will not be mixed with each other. When the piston 25 moves upward in the collection tube 21, the gas in the collection tube 23 will enter the collection tube 21, causing the cover plate 71 to rotate, so that a passage is formed in the collection tube 23, the pull rope 72 is stretched, the connecting ring 73 is driven to move, and the insertion rod 77 is driven to move. Move, stretch the connecting spring 74, drive the sealing round block 76 to move, seal the vent 78, and allow the wastewater to enter the collection tube 23 and the collection tube 21. After the collection tube 21 is filled with wastewater, under the action of gravity, the cover plate 71 rotates downward to block the collection tube 23, loosen the pull rope 72, and under the action of the connecting spring 74, drive the plug rod 77 to move away from the pull rope 72, drive the sealing round block 76 to move away from the collection tube 23, open the vent 78, and allow the gas in the sampling box 1 to enter the collection tube 23. Under the action of gravity and air pressure, the wastewater in the collection tube 23 flows back to the wastewater pool, avoiding mixing between each layer of wastewater collected. The rest of the structure is the same as that of Example 1.

[0050] Example 3, reference Fig. 9 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the collecting component includes a one-way rotating component 8 installed on one side of the limiting component 3, a transmission component 9 installed on one side of the one-way rotating component 8, a placement component 10 installed on the transmission component 9, and a collecting component 13 installed on the placement component 10; the one-way rotating component 8 includes a movable plate 84 fixedly connected to one side of the L-shaped rod 33, a plurality of movable grooves 83 with equal spacing arranged on the movable plate 84, an ejection spring 82 fixedly connected to the inner wall of the movable groove 83, a movable tooth 81 slidably connected to the inner side of the movable groove 83, the movable tooth 81 is fixedly connected to the ejection spring 82, and a ratchet 85 rotatably connected to the inner wall of the sampling box 1, and the movable tooth 81 conflicts with the ratchet on the ratchet 85.

[0051] Specifically, the one-way rotating assembly 8 drives the transmission assembly 9 to rotate, drives the placement assembly 10 to rotate, and drives the collection assembly 13 to rotate, so that wastewater from multiple layers can be collected at the same time. When the L-shaped rod 33 moves upward, it drives the movable plate 84 to move upward. Under the action of the movable tooth 81, since the ratchet teeth of the ratchet wheel 85 are tilted downward, they are just meshed with the movable teeth 81 at this time. The movable teeth 81 move upward, drive the ratchet wheel 85 to rotate, and drive the collection assembly 13 to rotate. The collection assembly 13 can be replaced for different layers of wastewater. When the L-shaped rod 33 moves downward, the movable plate 84 is driven to move downward, and the movable tooth 81 conflicts with the ratchet teeth of the ratchet wheel 85, so that the movable tooth 81 moves toward the inside of the movable groove 83 to compress the ejection spring 82. At this time, the movable tooth 81 cannot engage with the ratchet teeth of the ratchet wheel 85. Therefore, when the movable tooth 81 moves, the ratchet wheel 85 cannot rotate, thereby causing the one-way rotating component 8 to drive the transmission component 9 to rotate unidirectionally, and driving the collecting component 13 to rotate unidirectionally, so that the collecting component 13 collects the wastewater of each layer in turn.

[0052] Reference Fig.10 The transmission assembly 9 includes a second fixed shaft 95 rotatably connected to the inner wall of the sampling box 1, the ratchet 85 is fixedly connected to the second fixed shaft 95, a first bevel gear 91 rotatably connected to the inner bottom of the sampling box 1, a first fixed shaft 93 rotatably connected to the inner wall of the sampling box 1, a second bevel gear 92 fixedly connected to the first fixed shaft 93, the first bevel gear 91 is meshed with the second bevel gear 92, and the first fixed shaft 93 and the second fixed shaft 95 are connected via a belt 94.

[0053] Specifically, the ratchet 85 rotates, and since the second fixed shaft 95 is rotatably connected to the inner wall of the sampling box 1 via a bearing, the second fixed shaft 95 is driven to rotate. Under the action of the belt 94, since the first fixed shaft 93 is rotatably connected to the inner wall of the sampling box 1 via a bearing, the first fixed shaft 93 is driven to rotate, the second bevel gear 92 is driven to rotate, the first bevel gear 91 is driven to rotate, and the placement component 10 is driven to rotate.

[0054] Reference Figure 2 and Figure 3 The placement component 10 includes a rotating shaft 101 rotatably connected to the inner bottom of the sampling box 1, a first bevel gear 91 fixedly sleeved on the shaft wall of the rotating shaft 101, a placement plate 102 fixedly connected to the top of the rotating shaft 101, and a plurality of placement slots 103 symmetrically distributed on the placement plate 102.

[0055] Specifically, when the first bevel gear 91 rotates, the rotating shaft 101 is rotatably connected to the inner wall of the sampling box 1 through the bearing, thereby driving the rotating shaft 101 to rotate, driving the placement plate 102 to rotate, and then rotating the placement slot 103 to the bottom of the L-shaped tube 54. Different placement slots 103 can be switched to be located at the bottom of the L-shaped tube 54 to collect wastewater from different layers separately.

[0056] Reference Figure 2 , Figure 3 and Fig.11 The collecting assembly 13 includes a collecting bottle 131 placed in the placing groove 103, a supporting bar 132 fixedly connected to the inner side of the collecting bottle 131, a conical sealing block 134 slidably connected to the top of the inner side of the collecting bottle 131, and a telescopic spring 133 fixedly connected between the supporting bar 132 and the conical sealing block 134.

[0057] Specifically, when the placement slot 103 rotates to the bottom of the L-shaped tube 54, the collecting bottle 131 is driven to rotate, so that the collecting bottle 131 is located under the L-shaped tube 54, and one end of the L-shaped tube 54 slides on the top of the collecting bottle 131, so that the slider 41 slides upward in the first active cavity 42, compressing the reset spring 43. When the L-shaped tube 54 slides to the top of the truncated cone sealing block 134, the reset spring 43 is reset, driving the slider 41 to slide downward in the first active cavity 42, driving the L-shaped tube 54 to move downward, pressing the truncated cone sealing block 134 downward, and the telescopic spring 133 is compressed, and the top of the collecting bottle 131 is opened during the downward pressing of the truncated cone sealing block 134, and the wastewater in the collecting cylinder 21 is discharged from the discharge hole 55, flows to the top of the truncated cone sealing block 134, and flows into the collecting bottle 131 under the action of gravity, pressing the L-shaped tube 54 toward one side of the collecting cylinder 21, so that the insertion tube 53 slides on the connecting tube 51, compressing the tension spring 52, so that the L-shaped tube 54 is away from the collecting bottle 131, which is convenient for taking the collecting bottle 131 out of the placement groove 103 and facilitating the detection of the wastewater in the collecting bottle 131. The rest of the structure is the same as that of Example 2.

[0058] In summary, the working principle of the present invention is as follows: when in use, the sampling box 1 is placed in the wastewater to be sampled, and the driving motor 22 is started, so that the driving motor 22 rotates forward, driving the threaded rod 24 to rotate forward, so that the limit block 34 slides in the first through hole 31, so that the piston 25 moves upward on the inner side of the collection tube 21, and the gas in the collection tube 23 will enter the collection tube 21, so that the cover plate 71 rotates, so that a passage is formed in the collection tube 23, the pull rope 72 is stretched, and the connecting ring 73 is driven to move, and the insertion rod 77 is driven to move, so that the connecting spring 74 is stretched, and the sealing The sealing block 76 moves to seal the vent hole 78, and the waste water is pumped into the collection tube 21 through the collection tube 23, and the collected waste water is filtered through the filter cover 26. When the collection tube 23 extracts the waste water, the water flow drives the turbine 65 to rotate, drives the connecting shaft 64 to rotate, drives the bottom rod 62 to rotate, drives the fixing seat 61 to rotate, drives the cleaning cotton 63 to rotate, and cleans the outer surface of the filter cover 26, drives the baffle plate 32 to move upward, drives the L-shaped rod 33 to move upward, drives the moving plate 84 to move upward, and drives the ratchet 85 to rotate under the action of the movable tooth 81, drives the second fixed The fixed shaft 95 rotates, and under the action of the belt 94, the first fixed shaft 93 is driven to rotate. Under the action of the bevel gear set, the rotating shaft 101 is driven to rotate, the placement plate 102 is driven to rotate, and the collecting bottle 131 is driven to rotate, so that the collecting bottle 131 just rotates to the bottom of the L-shaped tube 54. Under the action of the L-shaped tube 54, the truncated cone sealing block 134 is pressed down, so that the top of the collecting bottle 131 is opened. When the piston 25 moves to the top of the collecting cylinder 21, the driving motor 22 is controlled to reverse, and the wastewater in the collecting cylinder 21 is pressed to the connecting pipe 51 and discharged from the discharge hole 55 and enters the collecting bottle 131. 1, when the piston 25 moves downward, the cover plate 71 moves downward under the action of gravity, blocks the collection tube 23, and opens the vent hole 78, so that the gas in the sampling box 1 enters the collection tube 23. Under the action of the gravity and air pressure of the water, the water in the collection tube 23 falls and re-enters the wastewater pool, so that when collecting the wastewater of each layer, no wastewater will remain in the collection tube 23. When the piston 25 moves upward again, the above action is repeated, so that another collection bottle 131 moves to the bottom of the L-shaped tube 54 to collect the wastewater, thereby being able to collect wastewater from different layers.
