Description

Technical Field

[0001] The invention relates to the technical field of water purification, and particularly relates to a water purification device for an ultrasonic scanning microscope. Background Art

[0002] A purification device is a device that breaks up excessive algae inside water through ultrasonic waves. When using the water purification device, the water to be purified is pumped into the inside of a connection box by a water pump, and the algae are separated according to different sizes through a layered filter screen. Ultrasonic waves are generated by an ultrasonic generator, and then the algae are broken up by the ultrasonic waves. After being broken up, the algae pass through the filter screen and are flushed out of the inside of the connection box, thereby playing a role in purifying the water. During this process, when the ultrasonic waves emitted by the ultrasonic generator pass through the algae, the ultrasonic waves can scan the algae, and then the signals are transmitted to a display screen through a connection line. Through the display screen, the algae magnified by the ultrasonic scanning microscope can be observed, and thus the content of algae in the water can be understood. In this way, the degree of water purification can be understood to a certain extent.

[0003] The inventor found in daily work that the purification device still has at least the following problems: When using the water purification device, the water to be purified is pumped into the inside of the connection box by a water pump, and the algae are separated according to different sizes through a layered filter screen. Ultrasonic waves are generated by an ultrasonic generator, and then the algae are broken up by the ultrasonic waves. After being broken up, the algae pass through the filter screen and are flushed out of the inside of the connection box. During this process, when the ultrasonic waves emitted by the ultrasonic generator pass through the algae, the ultrasonic waves can scan the algae, and then the signals are transmitted to a display screen through a connection line. Through the display screen, the algae magnified by the ultrasonic scanning microscope can be observed, and thus the content of algae in the water can be understood. In this way, the degree of water purification can be understood to a certain extent. However, in the actual use process, because most of the purification devices are installed outdoors, the display screen is prone to damage when being in the outdoor environment for a long time. Therefore, generally, people carry it with them and install the display screen on the purification device when needed. In this way, it is rather troublesome to observe the degree of water purification. Summary of the Invention

[0004] The purpose of the invention is to solve the deficiencies existing in the prior art, and a water purification device for an ultrasonic scanning microscope is proposed.

[0005] To achieve the above object, the invention adopts the following technical solutions: A water purification device for an ultrasonic scanning microscope, including a connection box, a water inlet pipe is arranged at the top of the connection box, a water pump is arranged in the middle section of the water inlet pipe, a water outlet pipe is arranged at the bottom of the connection box, filter nets are uniformly arranged inside the connection box, ultrasonic generators are uniformly arranged on the inner wall of the connection box, a display screen is arranged at the top of the connection box, a protection device is arranged on one side of the connection box, and a moving device is arranged on one side of the connection box. The protection device includes a rotating rod, the rotating rod is rotatably inserted on the side of the connection box away from the water inlet pipe, a first moving plate is fixedly connected to the end of the rotating rod away from the connection box, a second moving plate is arranged on the top of the first moving plate, a support plate is fixedly connected to the second moving plate, a connection frame is fixedly connected to the bottom of the support plate, a connection sleeve is slidably sleeved on the bottom of the connection frame, the bottom of the connection sleeve is fixedly connected to the top of the connection box, a first damping rod is fixedly connected to the top of the first moving plate, the top of the first damping rod is fixedly connected to the bottom of the second moving plate, a first spring is sleeved on the surface of the first damping rod, the bottom of the first spring is fixedly connected to the top of the first moving plate, and one end of the first spring close to the first damping rod is fixedly connected to the bottom of the second moving plate.

[0006] The effect achieved by the above components is that when using the protection device, slide the connection frame into the inside of the connection sleeve, and then set the support plate on the top of the display screen. Pull the second moving plate in the direction close to the first moving plate through the first spring, which can avoid the damage of the display screen outdoors to a certain extent.

[0007] Preferably, a clamping groove is opened at the bottom of the inner wall of the connection sleeve, a rubber frame is arranged on the inner wall of the clamping groove, and the top of the rubber frame is fixedly connected to the bottom of the connection sleeve.

[0008] The effect achieved by the above components is that after sliding the connection frame to the inner wall of the connection sleeve, the rubber frame is squeezed into the inside of the connection sleeve, which can well isolate the display screen inside the connection sleeve from the external environment, and thus avoid water seeping into the inside of the connection sleeve to a certain extent.

[0009] Preferably, a conical block is fixedly connected to the top of the support plate, the bottom of the conical block is larger than the top of the support plate, an elastic sleeve is sleeved on the surface of the first damping rod, the bottom of the elastic sleeve is fixedly connected to the top of the first moving plate, and the top of the elastic sleeve is fixedly connected to the bottom of the second moving plate.

[0010] The effects achieved by the above components are as follows: The function of the conical block can, to a certain extent, prevent water from accumulating on the top of the support plate. Since the bottom of the conical block is larger than the top of the support plate, this can, to a certain extent, prevent water from flowing along the connection frame into the interior of the connection sleeve. The elastic sleeve can, to a certain extent, prevent outdoor rainwater from falling into the interior of the first damping rod and the first spring, which can, to a certain extent, prevent the first damping rod and the first spring from rusting.

[0011] Preferably, a fixing groove is formed on one side of the connection box. The inner wall of the fixing groove is slidably connected with a moving frame. The moving frame is slidably sleeved on one side of the first moving plate. One end of the moving frame close to the first moving plate is fixedly connected with a second damping rod.

[0012] The effects achieved by the above components are as follows: When using the protection device, manually control the rotating rod to rotate on one side of the connection box, so that the support plate is arranged on the top of the connection box. At the same time, sleeved the moving frame on one side of the first moving plate, and then slide the moving frame into the fixing groove. By pulling the moving frame in the direction close to the first moving plate through the second spring, the moving frame can be well restricted in the fixing groove, so that the support plate can be well restricted on the top of the display screen.

[0013] Preferably, the moving device includes a motor. The motor is fixedly connected with one side of the connection box. The output end of the motor is fixedly connected with a threaded rod.

The thread direction on the surface of the threaded rod is opposite from the middle to both sides. Brushes are uniformly fixedly connected to the bottom of the moving strip.

[0014] The effects achieved by the above components are as follows: When using the moving device, start the motor. Drive the threaded rod to rotate through the motor. Under the restriction of the limiting rods, the two moving strips are driven to move relatively or away from each other at the same time. Since the brushes are uniformly arranged at the bottom of the moving strip, the broken algae can be well squeezed out from the top of the filter net.

[0015] Preferably, round rods are fixedly connected to the ends of the threaded rods away from the connection box. Belt pulleys are fixedly connected to the ends of the round rods away from the threaded rods. A connecting belt is sleeved on the surfaces of two adjacent belt pulleys.

[0016] The effects achieved by the above components are as follows: By connecting multiple threaded rods together through a connecting belt and a pulley, multiple threaded rods can be driven to rotate simultaneously.

[0017] Preferably, a third damping rod is uniformly and fixedly connected to the side of the pulley close to the round rod. The end of the third damping rod away from the pulley is fixedly connected with a rubber ring. A third spring is sleeved on the surface of the third damping rod. One side of the third spring is fixedly connected to the side of the pulley close to the round rod, and one end of the third spring close to the third damping rod is fixedly connected to one side of the rubber ring.

[0018] The effects achieved by the above components are as follows: The third spring squeezes the rubber ring away from the pulley, so that the rubber ring is squeezed to one side of the connection box, which can, to a certain extent, prevent water from seeping out at the connection between the round rod and the connection box.

[0019] Preferably, a limiting groove is formed on the side of the rubber ring away from the third damping rod. A connecting ring is arranged on the inner wall of the limiting groove. The connecting ring is fixedly connected to the surface of the round rod, and the connecting ring slides through and is inserted into one side of the connection box.

[0020] The effects achieved by the above components are as follows: The connecting ring is restricted inside the limiting groove, so that the rubber ring can closely adhere to the connection between the round rod and the connection box.

[0021] In the invention, by setting a protection device, when using the protection device, the connection frame is slid into the connection sleeve, and then the support plate is arranged on the top of the display screen. The first spring pulls the second moving plate towards the first moving plate, which can, to a certain extent, prevent the display screen from being damaged outdoors.

When using the water purification device, the water to be purified is pumped into the inside of the connection box 1 by the water pump 3, the algae are separated according to different sizes through the layered filter screens 5, ultrasonic waves are generated by the ultrasonic generators 6, and then the algae are broken by the ultrasonic waves. After being broken, the algae pass through the filter screens 5 and are flushed out of the inside of the connection box 1, thus playing a role in purifying the water body.

[0031] Refer to Figures 2 to 3, the protective device 8 includes a rotating rod 801 which is rotatably inserted on the side of the connection box 1 away from the water inlet pipe 2. One end of the rotating rod 801 away from the connection box 1 is fixedly connected to a first moving plate 802. A second moving plate 815 is arranged on the top of the first moving plate 802. A support plate 805 is fixedly connected to the second moving plate 815. A connection frame 806 is fixedly connected to the bottom of the support plate 805. A connection sleeve 808 is slidably sleeved on the bottom of the connection frame 806. The bottom of the connection sleeve 808 is fixedly connected to the top of the connection box 1. A first damping rod 803 is fixedly connected to the top of the first moving plate 802. The top of the first damping rod 803 is fixedly connected to the bottom of the second moving plate 815. A first spring 804 is sleeved on the surface of the first damping rod 803. The bottom of the first spring 804 is fixedly connected to the top of the first moving plate 802. One end of the first spring 804 close to the first damping rod 803 is fixedly connected to the bottom of the second moving plate 815. When using the protective device 8, slide the connection frame 806 into the inside of the connection sleeve 808, and then arrange the support plate 805 on the top of the display screen 7. Pull the second moving plate 815 in the direction close to the first moving plate 802 through the first spring 804, which can, to a certain extent, prevent the display screen 7 from being damaged outdoors. A clamping groove 809 is opened at the bottom of the inner wall of the connection sleeve 808. A rubber frame 807 is arranged on the inner wall of the clamping groove 809. The top of the rubber frame 807 is fixedly connected to the bottom of the connection sleeve 808. After sliding the connection frame 806 into the inner wall of the connection sleeve 808, the rubber frame 807 is squeezed into the inside of the connection sleeve 808, which can well isolate the display screen 7 inside the connection sleeve 808 from the external environment, and thus, to a certain extent, prevent water from penetrating into the inside of the connection sleeve 808. A conical block 810 is fixedly connected to the top of the support plate 805. The bottom of the conical block 810 is larger than the top of the support plate 805. An elastic sleeve 816 is sleeved on the surface of the first damping rod 803. The bottom of the elastic sleeve 816 is fixedly connected to the top of the first moving plate 802. The top of the elastic sleeve 816 is fixedly connected to the bottom of the second moving plate 815. The function of the conical block 810 can, to a certain extent, prevent water from accumulating on the top of the support plate 805. Because the bottom of the conical block 810 is larger than the top of the support plate 805, it can, to a certain extent, prevent water from flowing along the connection frame 806 into the inside of the connection sleeve 808. The elastic sleeve 816 can, to a certain extent, prevent outdoor rainwater from falling into the inside of the first damping rod 803 and the first spring 804, which can, to a certain extent, prevent the first damping rod 803 and the first spring 804 from rusting. A fixing groove 814 is opened on one side of the connection box 1. A moving frame 813 is slidably connected to the inner wall of the fixing groove 814. The moving frame 813 is slidably sleeved on one side of the first moving plate 802. One end of the moving frame 813 close to the first moving plate 802 is fixedly connected to a second damping rod 811. The end of the second damping rod 811 away from the moving frame 813 is fixedly connected to one side of the first moving plate 802.A second spring 812 is sleeved on the surface of the second damping rod 811. One end of the second spring 812 is fixedly connected to one side of the moving frame 813, and the end of the second spring 812 close to the second damping rod 811 is fixedly connected to one side of the first moving plate 802. When using the protection device 8, manually control the rotation of the rotating rod 801 on one side of the connection box 1, so that the support plate 805 is arranged on the top of the connection box 1. At the same time, sleeved the moving frame 813 on one side of the first moving plate 802, and then slide the moving frame 813 into the fixing groove 814. Pull the moving frame 813 in the direction close to the first moving plate 802 through the second spring 812, so as to well limit the moving frame 813 in the fixing groove 814, so that the support plate 805 can be well limited on the top of the display screen 7.,

[0032] Refer to Figures 4 to 7, the mobile device 9 includes a motor 901. The motor 901 is fixedly connected to one side of the connection box 1. The output end of the motor 901 is fixedly connected with a threaded rod 902. The threaded rod 902 is rotatably inserted into the inner wall of the connection box 1. A moving strip 903 is sleeved on the surface of the threaded rod 902. The inner wall of the connection box 1 is uniformly fixedly connected with limiting rods 904. The limiting rods 904 slidably penetrate and are inserted into one side of the moving strip 903. The thread direction on the surface of the threaded rod 902 is opposite from the middle to both sides. The bottom of the moving strip 903 is uniformly fixedly connected with brushes 905. When using the mobile device 9, the motor 901 is started, and the threaded rod 902 is driven to rotate by the motor 901. Under the restriction of the limiting rods 904, the two moving strips 903 are driven to move relatively or away from each other simultaneously. Since the brushes 905 are uniformly arranged at the bottom of the moving strip 903, the broken algae can be well squeezed out from the top of the filter net 5. The ends of the threaded rod 902 far away from the connection box 1 are both fixedly connected with round rods 906. The ends of the round rods 906 far away from the threaded rod 902 are both fixedly connected with belt pulleys 907. A connecting belt 908 is sleeved on the surfaces of two adjacent belt pulleys 907. The plurality of threaded rods 902 are connected together through the connecting belt 908 and the belt pulleys 907, so that the plurality of threaded rods 902 can be driven to rotate together at the same time. The third damping rods 912 are uniformly fixedly connected to the side of the belt pulley 907 close to the round rod 906. The ends of the third damping rods 912 far away from the belt pulley 907 are fixedly connected with rubber rings 910. The third springs 913 are sleeved on the surfaces of the third damping rods 912. One side of the third spring 913 is fixedly connected to the side of the belt pulley 907 close to the round rod 906. One end of the third spring 913 close to the third damping rod 912 is fixedly connected to one side of the rubber ring 910. The rubber ring 910 is squeezed towards the side away from the belt pulley 907 through the third spring 913, so that the rubber ring 910 is squeezed to one side of the connection box 1. This can, to a certain extent, prevent water from leaking out at the connection between the round rod 906 and the connection box 1. A limiting groove 911 is formed on the side of the rubber ring 910 far away from the third damping rod 912. A connecting ring 909 is arranged on the inner wall of the limiting groove 911. The connecting ring 909 is fixedly connected to the surface of the round rod 906. The connecting ring 909 slidably penetrates and is inserted into one side of the connection box 1, and the connecting ring 909 is restricted inside the limiting groove 911. This can make the rubber ring 910 closely adhere to the connection between the round rod 906 and the connection box 1.

[0033] Working principle: When using the water purification device, the water to be purified is pumped into the interior of the connection box 1 by the water pump 3. The algae are separated according to different sizes through the layered filter screen 5. The ultrasonic generator 6 generates ultrasonic waves, and then the algae are broken by the ultrasonic waves. After being broken, the algae are washed out of the interior of the connection box 1 after passing through the filter screen 5, thus playing a role in purifying the water body. When using the protection device 8, manually control the rotation of the rotating rod 801 on one side of the connection box 1, so that the support plate 805 is arranged on the top of the connection box 1. At the same time, the moving frame 813 is sleeved on one side of the first moving plate 802, and then the moving frame 813 is slid into the fixing groove 814. The moving frame 813 is pulled towards the first moving plate 802 by the second spring 812, so that the moving frame 813 is well restricted inside the fixing groove 814. In this way, the support plate 805 can be well restricted on the top of the display screen 7. Slide the connecting frame 806 into the connecting sleeve 808. After the connecting frame 806 slides to the inner wall of the connecting sleeve 808, the rubber frame 807 is squeezed into the connecting sleeve 808. In this way, the display screen 7 inside the connecting sleeve 808 can be well isolated from the external environment, and to a certain extent, water is prevented from penetrating into the connecting sleeve 808. Then, the support plate 805 is arranged on the top of the display screen 7. The second moving plate 815 is pulled towards the first moving plate 802 by the first spring 804. The function of the conical block 810 can prevent water from accumulating on the top of the support plate 805 to a certain extent, because the bottom of the conical block 810 is larger than the top of the support plate 805. In this way, water can be prevented from flowing into the connecting sleeve 808 along the connecting frame 806 to a certain extent. The elastic sleeve 816 can prevent outdoor rainwater from falling into the first damping rod 803 and the first spring 804 to a certain extent. In this way, the first damping rod 803 and the first spring 804 can be prevented from rusting, and the display screen 7 can be prevented from being damaged outdoors to a certain extent. When using the moving device 9, start the motor 901. The motor 901 drives the threaded rod 902 to rotate. Under the restriction of the limiting rod 904, the two moving strips 903 are driven to move relatively or away from each other at the same time. Because the brushes 905 are evenly arranged at the bottom of the moving strips 903, the plurality of threaded rods 902 are connected together by the connecting belt 908 and the pulley 907. In this way, the plurality of threaded rods 902 can be driven to rotate together at the same time. In this way, the broken algae can be well squeezed out from the top of the filter screen 5. The rubber ring 910 is squeezed away from the pulley 907 by the third spring 913, so that the rubber ring 910 is squeezed to one side of the connection box 1. The connecting ring 909 is restricted inside the limiting groove 911. In this way, the rubber ring 910 can be closely attached to the connection between the round rod 906 and the connection box 1. In this way, water can be prevented from seeping out from the connection between the round rod 906 and the connection box 1 to a certain extent.

[0034] It should be noted that all the damping rods in this case are telescopic dampers, which can absorb energy during the telescopic process.
