Description

Technical Field

[0001] This utility model relates to the field of stirring device technology, and in particular to a water quality testing stirring device with an anti-overflow function. Background Technology

[0002] A stirring device is used in water quality testing to ensure that substances in the water are evenly distributed. When using a stirring device, the water to be tested is poured into the stirring drum, and then the stirring rod is driven by a motor to stir the water, so that the substances inside the water are evenly distributed, thus avoiding errors caused by sedimentation to a certain extent.

[0003] The inventors found in their daily work that the stirring device still has at least the following problems: When using the stirring device, the water to be tested is poured into the stirring drum, and then the stirring rod is driven by the motor to stir the water, so that the substances inside the water are evenly distributed in the water, which avoids errors caused by sedimentation to a certain extent. However, in actual use, in order to prevent water from overflowing during stirring, a connecting cover is generally used to cover the outlet. When conducting water quality monitoring, the connecting cover needs to be opened, which is quite troublesome. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water quality testing and stirring device with an anti-overflow function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a water quality testing stirring device with anti-overflow function, comprising a stirring drum, a support frame fixedly connected to the bottom of the stirring drum, a connecting frame fixedly connected to the top of the support frame, a motor fixedly connected to the top of the connecting frame, a stirring rod rotatably inserted into the bottom of one side of the connecting frame, the motor and the stirring rod being connected together by a bearing, a limiting device provided at the top of the stirring drum, and a moving device provided at the bottom of the stirring drum, the limiting device comprising an arc-shaped plate disposed at the top of the stirring drum, a fixing groove formed at the bottom of the arc-shaped plate, support blocks uniformly fixedly connected to the top of the stirring drum, and a rotating rod slidably inserted through one side of the support block, the rotating rod being rotatably inserted into the inner wall of the fixing groove.

[0006] The effect achieved by the above components is as follows: when using the limiting device, the arc plate is manually controlled to rotate on the surface of the rotating rod, thereby setting the arc plate at the top of the mixing drum. This can prevent water from overflowing due to stirring to a certain extent, and the detection head of the water quality detection device can be inserted into the water. When water needs to be released, the arc plate is moved away from the top of the mixing drum, so as not to affect the water entering the interior of the mixing drum.

[0007] Preferably, a rubber conical sleeve is fixedly connected to the top of the mixing cylinder, and the rubber conical sleeve is fitted onto the surface of the arc-shaped plate.

[0008] The effect achieved by the above components is that by fitting the rubber conical sleeve onto the surface of the arc-shaped plate, the arc-shaped plate can be effectively confined to the top of the mixing drum, and to a certain extent, leakage from the gap between the arc-shaped plate and the mixing drum can be prevented.

[0009] Preferably, a connecting rod is fixedly connected to the surface of the arc-shaped plate, the connecting rod is slidably inserted through one side of the rubber conical sleeve, and a rubber block is fixedly connected to the end of the connecting rod away from the rubber conical sleeve.

[0010] The effect achieved by the above components is that by passing the connecting rod through the rubber conical sleeve, the rubber block is squeezed to the side of the rubber conical sleeve away from the arc plate, which can effectively restrict the rubber conical sleeve to the surface of the arc plate.

[0011] Preferably, the top of the arc-shaped plate is provided with a locking groove, and a rubber ring is fitted on the surface of the locking groove.

[0012] The effect achieved by the above components is that the rubber ring is manually placed on the inner wall of the locking groove, which can effectively restrain the curved plates together.

[0013] Preferably, the moving device includes a moving plate, which is slidably connected to the bottom of the inner wall of the mixing drum, and a rubber sleeve is fixedly connected to the surface of the moving plate.

[0014] The effect achieved by the above components is that when using the moving device, the moving plate is controlled to slide within the inner wall of the mixing drum, which can effectively control the volume of water that the mixing drum can hold. This eliminates the need to replace different models of mixing drums to mix water that requires water quality testing.

[0015] Preferably, a pressing rod is fixedly connected to the bottom of the movable plate, a connecting plate is fixedly connected to the bottom of the pressing rod, and a threaded rod is rotatably inserted through the top of the connecting plate, the threaded rod being threaded through the top of the support frame.

[0016] The effect achieved by the above components is: manual control of the screw rod rotation, which facilitates control of the movement of the moving plate on the inner wall of the mixing drum.

[0017] Preferably, the stirring rod is rotatably inserted into the top of the movable plate. A connecting groove is formed on one side of the top of the stirring rod where the first rotating blade is located. A sliding rod is slidably connected to the inner wall of the connecting groove. A second rotating blade is located on one side of the sliding rod. The first rotating blade is slidably sleeved on the top of the second rotating blade. A damping rod is fixedly connected to the top of the inner wall of the connecting groove. The bottom of the damping rod is fixedly connected to the top of the sliding rod. A spring is sleeved on the surface of the damping rod. The bottom of the spring is fixedly connected to the top of the sliding rod. The end of the spring near the damping rod is fixedly connected to the top of the inner wall of the connecting groove.

[0018] The effect achieved by the above components is that when the moving plate moves upward on the inner wall of the mixing drum, the spring is compressed, which causes the length of the stirring rod to change, thus allowing the stirring rod to rotate well on the inner wall of the mixing drum.

[0019] Preferably, an extrusion strip is slidably connected to one side of the connecting frame, and a bolt is rotatably inserted into one side of the extrusion strip, with the bolt threaded through and inserted into one side of the connecting frame.

[0020] The effect achieved by the above components is as follows: when the threaded rod is rotated to the appropriate position, the bolt is manually controlled to rotate, thereby causing the extrusion strip to be pressed against the top of the threaded rod. This makes it easier to press the extrusion strip against the top of the threaded rod, thus making it easier to restrict the threaded rod to the top of the connecting plate.

[0021] In this invention, by setting a limiting device, when using the limiting device, the arc plate is manually controlled to rotate on the surface of the rotating rod, thereby setting the arc plate at the top of the mixing drum. This can prevent water from overflowing due to stirring to a certain extent, and the detection head of the water quality detection device can be inserted into the water. When water needs to be released, the arc plate is moved away from the top of the mixing drum, so as not to affect the water entering the interior of the mixing drum. Attached Figure Description

[0027] Example 1, as Figure 1-4 As shown, a water quality testing stirring device with anti-overflow function is provided. A support frame 2 is fixedly connected to the bottom of the stirring drum 1, a connecting frame 3 is fixedly connected to the top of the support frame 2, a motor 4 is fixedly connected to the top of the connecting frame 3, and a stirring rod 5 is rotatably inserted into the bottom of one side of the connecting frame 3. The motor 4 and the stirring rod 5 are connected together by a bearing. A limit device 6 is provided at the top of the stirring drum 1, and a moving device 7 is provided at the bottom of the stirring drum 1. When using the stirring device, the water to be tested is poured into the inside of the stirring drum 1, and then the motor 4 drives the stirring rod 5 to stir the water, so that the substances inside the water are evenly distributed in the water, which avoids errors caused by sedimentation to a certain extent.

[0028] Reference Figure 2 and Figure 3The limiting device 6 includes an arc-shaped plate 603, which is disposed at the top of the mixing drum 1. A fixing groove 604 is provided at the bottom of the arc-shaped plate 603. Support blocks 601 are uniformly fixedly connected to the top of the mixing drum 1. A rotating rod 602 is slidably inserted through one side of the support block 601. The rotating rod 602 is rotatably inserted into the inner wall of the fixing groove 604. When using the limiting device 6, the arc-shaped plate 603 is manually controlled to rotate on the surface of the rotating rod 602, thereby setting the arc-shaped plate 603 at the top of the mixing drum 1. This can, to some extent, prevent water from overflowing due to stirring, and allow the detection head of the water quality testing device to be inserted into the water. When water needs to be released, the arc-shaped plate 603 is moved away from the top of the mixing drum 1, so as not to affect the water entering the interior of the mixing drum 1. A rubber conical sleeve 605 is fixedly connected to the top of the mixing drum 1, and the rubber conical sleeve 605 is fitted onto the arc-shaped plate 603. On the surface of plate 603, a rubber conical sleeve 605 is fitted onto the surface of the arc plate 603. This effectively confines the arc plate 603 to the top of the mixing drum 1 and, to some extent, prevents overflow from the gap between the arc plate 603 and the mixing drum 1. A connecting rod 606 is fixedly connected to the surface of the arc plate 603. The connecting rod 606 is slidably inserted through one side of the rubber conical sleeve 605. A rubber block 607 is fixedly connected to the end of the connecting rod 606 away from the rubber conical sleeve 605. By passing the connecting rod 606 through the rubber conical sleeve 605, the rubber block 607 is squeezed to the side of the rubber conical sleeve 605 away from the arc plate 603. A locking groove 608 is opened at the top of the arc plate 603. A rubber ring 609 is fitted onto the surface of the locking groove 608. The rubber ring 609 is manually fitted onto the inner wall of the locking groove 608, which effectively confines the arc plate 603 together.

[0029] Reference Figure 4The moving device 7 includes a moving plate 701, which is slidably connected to the bottom of the inner wall of the mixing drum 1. A rubber sleeve 702 is fixedly connected to the surface of the moving plate 701. When using the moving device 7, the moving plate 701 is controlled to slide within the inner wall of the mixing drum 1. This allows for precise control of the volume of water that the mixing drum 1 can hold, eliminating the need to replace different models of mixing drums 1 for mixing water that requires quality testing. A pressing rod 703 is fixedly connected to the bottom of the moving plate 701, and a connecting plate is fixedly connected to the bottom of the pressing rod 703. 704. A threaded rod 705 is rotatably inserted through the top of the connecting plate 704. The threaded rod 705 is threaded through the top of the support frame 2. The rotation of the threaded rod 705 is manually controlled, which facilitates the movement of the moving plate 701 on the inner wall of the mixing drum 1. The stirring rod 5 is rotatably inserted into the top of the moving plate 701. A connecting groove 708 is opened on one side of the top of the stirring rod 5 where the first rotating blade is located. A sliding rod 711 is slidably connected to the inner wall of the connecting groove 708. A second rotating blade is located on one side of the sliding rod 711. The first rotating blade is slidably sleeved on the second... A damping rod 709 is fixedly connected to the top of the upper part of the connecting groove 708 and the top of the upper part of the two rotating blades. The bottom of the damping rod 709 is fixedly connected to the top of the sliding rod 711. A spring 710 is sleeved on the surface of the damping rod 709. The bottom of the spring 710 is fixedly connected to the top of the sliding rod 711. One end of the spring 710 near the damping rod 709 is fixedly connected to the top of the inner wall of the connecting groove 708. When the moving plate 701 moves upward on the inner wall of the stirring drum 1, the spring 710 is compressed, thereby changing the length of the stirring rod 5. This allows... The stirring rod 5 rotates well on the inner wall of the stirring drum 1. An extrusion strip 706 is slidably connected to one side of the connecting frame 3. A bolt 707 is inserted into one side of the extrusion strip 706. The bolt 707 is threaded through and inserted into one side of the connecting frame 3. When the threaded rod 705 rotates to the appropriate position, the bolt 707 is manually controlled to rotate, thereby causing the extrusion strip 706 to be pressed against the top of the threaded rod 705. This makes it easier to press the extrusion strip 706 against the top of the threaded rod 705, thus making it easier to restrict the threaded rod 705 to the top of the connecting plate 704.

[0030] Working principle: When using the stirring device, the water to be tested is poured into the stirring drum 1. The motor 4 then drives the stirring rod 5 to stir the water, ensuring a uniform distribution of substances within the water. This helps to mitigate errors caused by sedimentation. When using the limiting device 6, the arc-shaped plate 603 is manually rotated on the surface of the rotating rod 602. The rubber ring 609 is manually fitted onto the inner wall of the locking groove 608, effectively securing the arc-shaped plate 603. The arc-shaped plate 603 is then positioned at the top of the stirring drum 1. A rubber conical sleeve 605 is fitted onto the surface of the arc-shaped plate 603. The connecting rod 606 passes through the rubber conical sleeve 605, pushing the rubber block 607 to the side of the rubber conical sleeve 605 away from the arc-shaped plate 603. This effectively confines the rubber conical sleeve 605 to the surface of the arc-shaped plate 603, thus securing the arc-shaped plate 603 at the top of the stirring drum 1 and preventing leakage from the gap between the arc-shaped plate 603 and the stirring drum 1. This also helps to prevent water leakage. Because of the stirring, the water overflows, and the detection head of the water quality testing device can be inserted into the water. When water needs to be drained, the arc plate 603 is moved away from the top of the mixing drum 1 so as not to affect the water entering the interior of the mixing drum 1. When using the moving device 7, the threaded rod 705 is manually controlled to rotate, which makes it easier to control the movement of the moving plate 701 on the inner wall of the mixing drum 1. When the threaded rod 705 rotates to the appropriate position, the bolt 707 is manually controlled to rotate, which causes the extrusion strip 706 to press against the top of the threaded rod 705. This makes it easier to press the extrusion strip 706 against the top of the threaded rod 705, which makes it easier to limit the threaded rod 705 to the top of the connecting plate 704. This can effectively control the volume of water that the mixing drum 1 can hold. This eliminates the need to replace different models of mixing drum 1 to stir the water that needs to be tested. When the moving plate 701 moves upward on the inner wall of the mixing drum 1, the spring 710 is compressed, which causes the length of the stirring rod 5 to change. This can effectively make the stirring rod 5 rotate on the inner wall of the mixing drum 1.

[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
