Description
Technical Field
[0001] The present invention relates to the technical field of sewage detection, and particularly to a sewage pH detection device. Background Technique
[0002] Water is the basis for human survival and an important production resource for human production activities. People use appropriate purification methods to purify water to meet the needs of human life or production processes for water. With the shortage of water resources and the intensification of water pollution, people generally attach importance to the protection of water resources, the prevention and control of water pollution, and water reuse work. Water quality testing is even more important for determining water treatment plans, selecting reasonable water treatment plans and processes, and monitoring water pollution and treatment to ensure the normal operation of the project. Sewage usually refers to the discharged water from life and production that is contaminated to a certain extent. In the process of sampling with existing sewage pH detection devices, since there is a layer of floating matter on the surface of the sewage, the floating matter easily reaches the inside of the detector, making sampling and detection difficult and having a certain degree of randomness.
[0003] In view of the above, we provide a sewage pH detection device to solve the above problems. Summary of the Invention
[0004] In view of the above situation, the present invention provides a sewage pH detection device. The rotating frame of this device can rotate to stir the surface of the sewage, and can also make the air outlet block on the surface of the frame swing and blow air. When blowing air, the floating matter on the surface of the sewage is blown to the outside.
[0005] A sewage pH detection device includes a frame body. A fixed ring is integrally provided on the lower surface of the frame body. A switching groove is formed on the outer surface of the fixed ring. A lifting frame is lapped on the surface of the switching groove. A rotating frame is rotatably provided on the lower surface of the frame body. A lifting frame is slidably provided on one side of the rotating frame. A maintaining spring is provided between the rotating frame and the lifting frame. A sampling cylinder is rotatably provided on one side of the lifting frame. An adjusting bar is slidably provided on the upper surface of the lifting frame. A contact column is slidably provided on the lower surface of the adjusting bar. A contact bar is integrally provided on the upper surface of the sampling cylinder. A reset spring is provided between the lifting frame and the sampling cylinder. A top bar is rotatably provided on one side of the rotating frame. A rotating column is rotatably provided on the lower surface of the frame body.
[0006] The beneficial effects of the above technical solutions are as follows:
[0007] The rotating frame set in this solution can rotate to stir the surface of the sewage, and can make the air outlet blocks on the surface of the frame swing and blow air. When blowing air, the floating objects on the surface of the sewage are blown to the outside. The lifting frame can move up and down during the rotation, so that the sampling cylinder moves up and down, which can stir the sewage inside the rotating frame. And the sampling cylinder can automatically close and open during the rising process at the top, so that the sewage automatically contacts the detection rod. During the rising process, the detection rod can also rotate and store energy to achieve the effect of swinging back and forth. The back-and-forth swing of the detection rod can make the sewage contact horizontally during the sewage discharge process, increasing the contact range between the bottom of the detection rod and the sewage. The liquid inlet blade can automatically move away from the filter cylinder at a suitable position, creating an interval between the two sides and blocking certain floating objects.

Detailed implementation mode
[0017] Regarding the foregoing and other technical contents, features and effects of the present invention, they can be clearly presented in the following detailed description of the embodiments in conjunction with the attached Figures 1 to 8 drawings. The structural contents mentioned in the following embodiments are all referenced to the drawings of the specification.
[0018] This embodiment provides a sewage pH detection device, as shown in the attached Figures 1 - 8 drawings. The attached Figure 1 is the overall structure diagram of this solution. The attached Figure 2 is the attached Figure 1 cutting diagram of the Figure 3 Hiding the filter cylinder 19, the internal structure of the filter cylinder 19 can be seen. The attached Figure 4 Cut along the middle of the sampling cylinder 7. The attached Figure 5 Taken from the attached Figure 4 There is a wavy line on the left side of the attached Figure 4 Since it is inconvenient to display the conveying column 29 in the attached Figure 4 drawings, a separate drawing is listed for display. The attached Figure 6 Partially cut the rotating frame 5. The attached Figure 7 Only cut the lifting frame 4 and cut the general part of the lifting frame 4. The attached Figure 8 Cut the upper side of the filter cylinder 19 to facilitate viewing the structure above the discharge blade 20. The power source of this solution depends on the motor of the driving gear 23. An installation position for the motor needs to be reserved above the driving gear 23 so that the motor can drive the driving gear 23 to rotate. Since the motor belongs to the prior art, the motor is not shown in this solution, which does not mean that this solution does not have motor drive. Driven by the motor, the driving gear 23 rotates on the frame 1. As described in the attached Figure 1 drawings, a rotating frame 5 is meshed outside the driving gear 23, and a small gear is integrally arranged above the driving gear 23. This small gear meshes with the other rotating column 16. Therefore, the driving gear 23 can drive two groups of mechanisms to rotate. First, the effect brought by the rotation of the rotating frame 5. The filter cylinder 19 is limited and slid under the rotating frame 5. The filter cylinder 19 is slidably arranged under the rotating frame 5, and relative sliding can be carried out between the two, but relative rotation cannot be carried out. Therefore, when the rotating frame 5 rotates, the filter cylinder 19 rotates. The fixing ring 2 is extended and arranged below the frame 1. Therefore, the fixing ring 2 is stationary relative to the rotating frame 5. A switching groove 3 is arranged on the outer surface of the fixing ring 2. The switching groove 3 is shown in the attached Figure 3 drawings. The switching groove 3 is an annular groove, but has a fork, as shown in the attached Figure 7As shown, this fork allows the lifting frame 4 to move upward, as shown in the attached drawings of the specification. Figure 7 As shown, the lifting frame 4 is vertically slidably arranged on one side of the rotating frame 5, and a maintaining spring 6 is arranged between the lifting frame 4 and the rotating frame 5. There is an integrally arranged cylinder at the top of the lifting frame 4, and this cylinder can reach inside the switching groove 3, and it enters the switching groove 3 through the fork. The maintaining spring 6 is in a stretched state in the attached drawings of the specification, so that the maintaining spring 6 will make the cylinder enter the fork, as shown in the attached drawings of the specification. Figure 7 As shown, when the rotating frame 5 rotates clockwise, it can enter the fork, while when the rotating frame 5 rotates counterclockwise, the lifting frame 4 is maintained at the top. And when the cylinder is inside the switching groove 3, the maintaining spring 6 is in a compressed state. Therefore, when rotating clockwise, the cylinder always remains inside the switching groove 3, and when rotating counterclockwise, the cylinder will reach above the fixed ring 2 from the switching groove 3 along the fork. In this way, the lifting frame 4 has two positions. The first is to move up and down inside the switching groove 3, and the second is above the fixed ring 2. Thus, depending on the rotation direction of the rotating frame 5, the position of the lifting frame 4 is changed, that is, the lifting frame 4 can move up and down during the rotation process (when inside the switching groove 3, in this solution, the vertical width of the fork in the switching groove 3 is very large, so that the lifting frame 4 can move up and down a long distance. Therefore, in this solution, the situation where the sampling cylinder 7 cannot take samples is not considered, that is, it can move up and down a long distance). When sewage enters the sampling cylinder 7, the lifting frame 4 will move up and down to achieve the effect of stirring the sewage, and the sampling cylinder 7 can be rotatably arranged on the lifting frame 4 to perform self-rotating sealing. There is a reset spring above the sampling cylinder 7, and the reset spring is a kind of torsion spring. In the attached drawings of the specification. Figure 7 At this time, the reset spring is in an untwisted state. There is an adjusting strip 8 slidably arranged above the sampling cylinder 7 (the adjusting strip 8 is slidably arranged on the lifting frame 4, and there is a spring in the middle of the adjusting strip 8 to keep the adjusting strip 8 above the sampling cylinder 7). There is a laterally sliding contact post 9 below the adjusting strip 8. Let's introduce how the sampling cylinder 7 rotates automatically. When the sampling cylinder 7 is at the top (that is, when the cylinder at the top of the lifting frame 4 is above the fixed ring 2), as shown in the attached drawings of the specification. Figure 7 As shown, at this time, the lifting frame 4 moves downward integrally, and a top strip 11 is rotatably arranged on one side of the rotating frame 5. A bending spring 12 is arranged on one side support of the top strip 11. The bending spring 12 is an arc-shaped spring, which can support the top strip 11 during rotation (using support instead of connecting to the top strip 11, so that when the adjusting strip 8 moves downward, it can make the adjusting strip 8 control the top strip 11 to rotate clockwise, as Figure 7As shown, the right side of the top bar 11 is heavier (towards the direction of the adjustment bar 8), so that after the top bar 11 rotates clockwise, it can be reset under the action of gravity (there is a clamping structure to prevent the top bar 11 from rotating to the other side). When the adjustment bar 8 approaches from bottom to top, since the elastic force of the bending spring 12 is greater than the spring in the middle of the adjustment bar 8, the adjustment bar 8 will move downward along the lifting frame 4 (relative to the lifting). Since the contact bar 10 is integrally provided above the sampling cylinder 7, when the upper part of the adjustment bar 8 is blocked by the top bar 11, the contact column 9 remains in place, causing the contact bar 10 to rotate, which will make the sampling cylinder 7 rotate, achieving the effect of closing the sampling cylinder 7. In this way, a part of the sewage will be stored in the sampling cylinder 7. As the adjustment bar 8 continues to move downward, the contact bar 10 has to rotate. The shape of the continuous bar is a structure of an arc plus a vertical part. The vertical setting is to make the sampling cylinder 7 rotate 90 degrees and maintain the state for a longer time, so that the sampling cylinder 7 moves upward for a long time and reaches above the detection strip (below the detection rod 13 is the detection strip). Since there is a notch at the bottom of the contact bar 10, when the contact column 9 reaches this notch, the contact between the two is disengaged. In this way, the sampling cylinder 7 quickly resets under the action of the return spring, achieving the effect of releasing the sewage. The released sewage will reach below the detection strip for detection, hitting the detection strip for detection. The detection strip can be a test paper or a detection probe, and the detection can be carried out using existing technologies. After that, as the adjustment bar 8 pushes open the top bar 11 and crosses the top bar 11, as shown in the attached instruction Figure 7 As shown, and the adjustment bar 8 will be reset under the action of the middle spring, causing the contact column 9 to return. There is also a spring on one side of the contact column 9, so that it moves along the left side of the contact bar 10 (the return of the contact column 9 depends on the extrusion of the spring on one side, and at the same time, it can be reset directly above the contact bar 10 when reaching the upper part, which is convenient for re - contacting the inclined plane when moving downward). By squeezing the spring on one side of the contact column 9, the contact column 9 will reset above the contact bar 10 when reaching the bottom. With the next movement, this action can continue. In this way, during the upward movement, the rotation of the sampling cylinder 7 is controlled and maintained for a period of time. After reaching the top, it will rotate and reset to release the sewage, achieving the effect of falling onto the contact rod for contact detection. In order to prevent the detection rod 13 from blocking during the up - and - down movement of the lifting frame 4, the lifting frame 4 is rotatably arranged on the rotating frame 5, and a swinging spring 14 is provided at the top. The swinging spring 14 is also a torsion spring. The swinging spring 14 is in the untwisted state in the attached instruction Figure 7 As shown in the figure, and on one side of the lifting frame 4, a circular cross - bar is extended, just above the guide bar 15. The guide bar 15 is arranged on both sides of the detection rod 13 as shown in the attached instruction Figure 7As shown, at this time, the lifting frame 4 moves downward and contacts the inclined surface of the left guide bar 15, so that the detection rod 13 rotates counterclockwise to achieve the effect of the detection rod 13 rotating. The rotation of the detection rod 13 can make the bottom of the detection rod 13 staggered from the downward movement of the lifting frame 4, and the same is true for the lifting frame 4 moving upward, which will contact the inclined surface of the right guide bar 15, so that the detection rod 13 rotates clockwise to reopen the sampling tube 7, and corresponds to the release of the sampling tube 7. In this way, when the sampling tube 7 releases sewage, the detection rod 13 will also rotate and reset to achieve a swinging effect. During the swinging process of the detection rod 13, it hits the sewage to achieve a sufficient mixing effect.
[0019] The previous paragraph introduced that the rotating frame 5 drives the filter cartridge 19 to rotate together. One side of the filter cartridge 19 is lapped with an extending frame 27, and the extending frame 27 is vertically slidably arranged on the frame body 1. Therefore, the position of the extending frame 27 can control the position of the filter cartridge 19. In order to enable the filter cartridge 19 to filter the floating substances on the surface of the sewage, a liquid inlet blade 24 is slidably arranged at the bottom of the filter cartridge 19. The extension control of the extending frame 27 depends on the rotating column 16 of this solution. A first groove 26 is opened on the rotating column 16. Since there is a large height deviation between the head and the tail of the first groove 26, when the rotating column 16 rotates, the extending frame 27 can be moved downward. Since a certain transmission ratio can be set for the driving gear 23, the rotating column 16 can be set to rotate slowly, which is equivalent to slowly extending the extending frame 27 downward, so that the filter cartridge 19 moves downward during rotation. Since the sliding distance of the liquid inlet blade 24 on the support rod 37 is limited and the matching spring 25 is always in a stretched state, when the filter cartridge 19 continuously extends downward and there is no sliding gap between the support rod 37 and the liquid inlet blade 24, an analysis will be generated between the liquid inlet blade 24 and the filter cartridge 19. Since the filter cartridge 19 rotates, the sewage enters the sampling cylinder 7 through the fine gaps. As the filter cartridge 19 rises, the bottom is closed and the sewage cannot be discharged. In this way, the sampling of the sewage is completed. The frame body 1 of this solution is for handheld sampling, and this solution also has the effect of blowing the surface of the sewage. A side rod 28 is integrally arranged at the edge of the frame body 1. A conveying column 29 is slidably arranged on the surface of the side rod 28. One side of the conveying column 29 extends towards the middle of the frame body 1. A second groove 31 is opened at the bottom of the rotating column 16. The second groove 31 is a periodic groove and has multiple waves, so that the output column can move up and down on the side rod 28. The up and down movement of the output column on the side rod 28 can make the air outlet block 30 rotate outward. Because a notch is arranged on one side of the air outlet block 30 and the conveying column 29 is lapped on the surface of the notch, the up and down movement of the conveying column 29 can make the air outlet block 30 rotate. An air conveying column 29 is connected above the air outlet block 30, and an external connecting pipe 32 is connected above the air conveying column 29. One side of the external connecting pipe 32 needs to be externally connected to a blower to ensure that the blower blows air towards the external connecting pipe 32. In order to ensure the rotation and air outlet of the air outlet block 30, a section between the rotating block and the air conveying column 29 is connected by a flexible pipe and has a certain length. The air outlet block 30 also has the effect of rotating and blowing air outward and not blowing air inward when rotating inward, so as to ensure that the floating substances are blown outside the filter cartridge 19, as shown in the attached Figure 5When the conveying column 29 moves upward and the support block 34 remains stationary, the valve 35 cannot block the notch, allowing air to reach the inside of the air outlet block 30. At the end of the upward movement, the release strip 33 contacts the side cylinder of the positioning block 36. One side of the positioning block 36 is integrally provided with a cylinder. During the upward movement of the release strip 33, it will push against the cylinder, causing the positioning block 36 to disengage from the valve 35 (a slot adapted to the positioning block 36 is provided on the valve 35). When the positioning block 36 disengages from the valve 35, the valve 35 is released. There is a spring between the upper part of the valve 35 and the support block 34. This spring is in a stretched state in the figure, with its head connected to the support block 34 and its tail connected to the valve 35. Therefore, once the valve 35 is released, the valve 35 will re-block the conveying column 29 under the action of the spring and will continuously block the conveying column 29 as the conveying column 29 moves downward, causing the positioning block 36 to re-lock the valve 35, as shown in the attached instruction manual Figure 5 As shown, a cyclic operation is formed, that is, the air outlet block 30 rotates outward to discharge air, and closes when rotating inward, and the fan continuously conveys air without the need to be turned off. Finally, how to discharge sewage in this solution is introduced. Since this solution is handheld, a part of the frame 1 needs to be placed below the liquid level. Therefore, as this solution continues to operate (at this time, the rotating frame 5 does not rotate in the reverse direction, and this solution limits the reverse rotation of the lifting frame 4 into the switching groove 3), the rotating frame 5 rotates forward, causing the rotating column 16 to rotate one circle, that is, the filter cylinder 19 first moves downward and then upward. At this time, the lifting frame 4 is still at the top, as shown in the attached instruction manual Figure 1 One side of the first slot 26 can be set to be relatively stable (as shown on the right side of the first slot 26 in Figure 1 ). At this time, since the filter cylinder 19 has entered the sewage, the rotating frame 5 is controlled to move in the reverse direction, that is, the lifting frame 4 moves downward, and then swings up and down for sampling. After sampling, it continues to rotate forward, causing the lifting frame 4 to move upward. The lower surface of the lifting frame 4 (the lower surface of the lifting frame 4 is integrally provided with a cross frame 17) can contact the bottom of the discharge block 21 at the end of the upward movement. One side of the discharge block 21 is an inclined surface, and the upper part of the forked block 18 is also an inclined surface. When the forked block 18 moves upward, it pushes against the discharge block 21 to move horizontally. The movement of the discharge block 21 can push against the discharge blade 20 to rotate, achieving the effect of diverging the inside, as shown in the attached instruction manual Figure 1As shown, a first spring 22 (the first spring 22 is a torsion spring that can cause the discharge blade 20 to twist and reset) is provided above the discharge blade 20. Since the attached drawing is static, the discharge blade 20 will then reset under the action of the first spring 22 to achieve a closed effect. The bifurcated block 18 is formed by combining two into one, and one side of the bifurcated block 18 has spring support. The upper part of the discharge block 21 is sharp, so during the downward movement of the cross frame 17, it can pass above the discharge block 21 to cause the bifurcated block 18 to move horizontally and reach the lower side of the discharge block 21 again.
