Description

Technical Field

[0001] This utility model relates to the technical field of float level transmitters, and specifically to a float level transmitter. Background Technology

[0002] A float level transmitter is an important device for measuring liquid level. It mainly consists of a float, a connecting rod, and the transmitter body. When the liquid level changes, the float moves up and down with the rise and fall of the liquid. The movement of the float is transmitted to the sensor inside the transmitter through the connecting rod. The sensor converts the displacement of the float into an electrical signal output.

[0003] When in use, float-type liquid transmitters can accurately measure various types of water, including clean water, industrial water, and domestic water. However, when measuring viscous liquids, the surface of the float may have viscous liquid on it after the measurement is completed. If it is not cleaned and wiped off in time after use, the viscous liquid may solidify on the surface of the float, causing errors in the next measurement.

[0004] After the measurement is completed, the surface of the float needs to be cleaned. This requires the operator to disassemble the device for cleaning. However, if the float level transmitter is installed on the top of a large oil tank, the operator may need to climb to the top of the oil tank to disassemble the device for cleaning, which is quite troublesome.

Detailed Implementation

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0028] like Figures 1-4 As shown, this embodiment proposes a float 3 level transmitter, including a mounting plate 1, a guide rod 2, and a float 3. The guide rod 2 is fixedly mounted on the mounting plate 1, and the float 3 is slidably mounted on the guide rod 2. It also includes a connecting frame 101, a ball-moving assembly, a top plate 102, a mounting bracket 103, a cleaning pushing assembly, a cleaning rotating assembly, and a wiping cloth 104. Two connecting frames 101 are provided, both fixedly mounted on the bottom end of the mounting plate 1. The ball-moving assembly is mounted on the two connecting frames 101, and the top plate 102 is mounted on the ball-moving assembly. Two mounting brackets 103 are provided, each fixedly mounted on the bottom end of the mounting plate 1. Two cleaning pushing assemblies are provided. Two cleaning push components are respectively mounted on two mounting brackets 103. Two cleaning rotation components are provided, each mounted on one of the two cleaning push components. Two wiping cloths 104 are provided, each mounted on one of the two cleaning rotation components. Specifically, when wiping the float 3, the float 3 can be moved to the wiping cloth 104 by the ball lifting component. Then, the wiping cloth 104 is attached to the float 3 by the cleaning push component. Then, the wiping cloth 104 is rotated on the float 3 by the cleaning rotation component to wipe it. The bottom of the mounting bracket 103 is higher than the highest point of the liquid in the container, which can ensure that the solution inside the container will not adhere to it during wiping.

[0029] In this embodiment, reference Figure 2 The ball moving assembly includes a drive screw 201, a motor 202, and a drive block 203. The drive screw 201 is rotatably mounted between one of the connecting brackets 101 and the mounting plate 1. The motor 202 is mounted on the mounting plate 1, and the output end of the motor 202 is fixedly connected to the top end of the drive screw 201. The drive block 203 is threadedly connected to the drive screw 201.

[0030] In this embodiment, reference Figure 2 The ball-moving assembly also includes a slide rod 204 and a slide plate 205. The slide rod 204 is fixedly installed between another connecting frame 101 and the mounting plate 1. The slide plate 205 is slidably installed on the slide rod 204. The top plate 102 is fixedly installed between the slide plate 205 and the drive block 203. Specifically, when the float 3 is moved upward, the motor 202 can be started. The motor 202 drives the drive screw 201 to rotate between the connecting frame 101 and the mounting plate 1, thereby driving the drive block 203 to move on the drive screw 201. It can also drive the top plate 102 to move upward, and at the same time drive the slide plate 205 to move on the slide rod 204. The top of the top plate 102 has a groove, and the groove of the top plate 102 is adapted to the bottom of the float 3, thereby lifting the float 3 and moving it to a position horizontal with the wiping cloth 104.

[0031] In this embodiment, reference Figure 3 The cleaning push assembly includes a cylinder 301 and a pusher frame 302. The cylinder 301 is mounted on the mounting frame 103, and the pusher frame 302 is fixedly connected to the output end of the cylinder 301. Specifically, after the wiping cloth 104 and the float 3 are at the same horizontal position, the cylinder 301 can be activated. The cylinder 301 drives the pusher frame 302 to move forward, thereby driving the wiping cloth 104 to move forward and contact the float 3. The wiping cloth 104 is set as a hemispherical shape, the bottom end of the wiping cloth 104 is horizontal, and the inner side wall of the wiping cloth 104 can be attached to the outer side wall of the float 3. When the two wiping cloths 104 and the float 3 are at the same horizontal position, the bottom end of the wiping cloth 104 and the top end of the top plate 102 are at the same horizontal position, thereby ensuring that when the wiping cloth 104 moves forward and attaches to the surface of the float 3, it can slide on the upper surface of the top plate 102.

[0032] In this embodiment, reference Figure 4 The cleaning rotating assembly includes a second motor 401, a drive gear 402, a rotating shaft 403, and a gear ring 404. The second motor 401 is mounted on a pusher frame 302. The drive gear 402 is fixedly connected to the output end of the second motor 401. The rotating shaft 403 is rotatably mounted on the side of the pusher frame 302, and the wiping cloth 104 is detachably mounted on the side of the rotating shaft 403. The gear ring 404 is fixedly mounted on the rotating shaft 403, and the drive gear 402 meshes with the gear ring 404. Specifically, when the wiping cloth 104 is in contact with the surface of the float 3, the second motor 401 can be activated, driving the drive gear 402. The drive gear 402 rotates, driving the meshing gear ring 404 to rotate. The gear ring 404 drives the rotating shaft 403 to rotate, and the rotating shaft 403 drives the wiping cloth 104 to rotate on the surface of the float 3. The wiping cloth 104 is made of plastic, so it can be folded during rotation without obstruction. A protective cover 105 is fixedly installed on the push frame 302. The drive gear 402 and the gear ring 404 are both located inside the protective cover 105, and the rotating shaft 403 is rotatably mounted on the protective cover 105. The protective cover 105 can protect the meshing of the drive gear 402 and the gear ring 404, and also provides support for the rotating shaft 403.

[0033] In this embodiment, when using the transmitter, the mounting plate 1 is first installed on the top of the container, and the slide rod 204 and float 3 are placed inside the container. Liquid is added to the container, causing the float 3 to float on the guide rod 2 until it is level with the liquid. After stopping, the float 3 transmits distance data to the transmitter module 4. It should be noted that the transmitter module 4 is mounted on the mounting plate 1. When it is necessary to measure other liquids inside the container, the liquid can be drained, and the starter motor 202 can be started. The motor 202 drives the drive screw 201 to rotate between the connecting frame 101 and the mounting plate 1, thereby causing the drive block 203 to move on the drive screw 201 and also causing the top plate 102 to move upwards. The sliding plate 205 moves on the sliding rod 204, and the top plate 102 presses against the bottom of the float 3 to move it upward to the same level as the wiping cloth 104. Then, the cylinder 301 is activated, which drives the push frame 302 to move forward, thereby driving the wiping cloth 104 to move forward and contact the float 3, so that the wiping cloth 104 adheres to the float 3. Finally, the second motor 401 is activated, which drives the drive gear 402 to rotate. The drive gear 402 drives the gear ring 404 that meshes with it to rotate. The gear ring 404 drives the rotating shaft 403 to rotate. The rotating shaft 403 drives the wiping cloth 104 to rotate on the surface of the float 3, which can wipe off the solution adhering to the surface of the float 3. Then, when the container is filled with new liquid, the float 3 can be measured again.

[0034] It should be added that the wiping cloth 104 is detachably mounted on the rotating shaft 403. If it is used for a long time, it can be removed and replaced. Alcohol swabs or easy-to-clean materials can be attached and adhered to the inner wall of the wiping cloth 104 to make its cleaning effect better.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
