Description

Technical Field

[0001] The utility model relates to the technical field of liquid level sensor control devices, and particularly relates to a liquid level sensor control device. Background Technique

[0002] A liquid level sensor control device is a device for fixing the position of a liquid level sensor to ensure the stability of the liquid level sensor during use.

[0003] For example, a liquid level sensor control device with the publication number of "CN220270552U" has a servo motor installed on the surface of the end plate at the top. This liquid level sensor control device controls the lifting movement of the sensor module and the sampling component at the bottom through the servo motor at the top and the rod at the bottom. Therefore, it can avoid the long-term operation of the sensor module, extend the service life of the sensor module, and at the same time reduce the probability of damage caused by long-term contact with the liquid, and reduce the interference of external liquid fluctuations on the accuracy of the liquid level acquisition data. However, in the use of the liquid level sensor control device, the control device and the liquid level sensor are integrated and cannot be disassembled. When repairing, the entire liquid level sensor control device needs to be removed and then reinstalled. Coupled with the multi-position fixation of the liquid level sensor control device, it increases the difficulty of using the liquid level sensor control device and reduces the working efficiency of the liquid level sensor control device. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems of increasing the difficulty of using the liquid level sensor control device and reducing the working efficiency of the liquid level sensor control device, and to propose a liquid level sensor control device.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] Design a liquid level sensor control device, including a top plate and a vertical plate. The left end of the top of the top plate is fixedly connected to the bottom of the vertical plate. The right end of the top of the top plate is fixedly connected with a square plate. A fixing structure is connected to the inner wall of the square plate. A square block is connected to the inner wall of the fixing structure. A vertical plate is fixedly connected to the front of the bottom of the top plate. A control structure is connected to the outer wall of the vertical plate.

[0007] Preferably, the fixing structure includes a screw rod and a handle. The outer wall of the screw rod is threadedly connected to the inner wall of the square plate. The right side of the screw rod is fixedly connected to the left side of the handle. The left side of the outer wall of the screw rod is rotatably connected to a straight plate. A round rod is fixedly connected to the top of the straight plate. A bracket is slidably connected to the end of the outer wall of the round rod.

[0008] Preferably, the outer wall of the bracket is slidably connected to the notch at the top of the top plate, and the inner wall of the bracket is inserted into the end of the outer wall of the square block.

[0009] Preferably, a liquid level sensor is fixedly connected to the bottom of the square block.

[0010] Preferably, the control structure includes a horizontal plate and a curved plate. The left ends of the inner sides of the two horizontal plates are fixedly connected to the front and rear sides of the vertical plate respectively. The right end of the inner side of the horizontal plate is rotatably connected to the upper part of the outer wall of the curved plate. A bolt is threadedly connected to the lower right side of the curved plate.

[0011] Preferably, the left side of the outer wall of the bolt is threadedly connected to the right side of the vertical plate.

[0012] The beneficial effect of a liquid level sensor control device proposed by the present utility model is as follows: By inserting the front and rear ends of the outer wall of the square block in the fixed structure into the inner walls of the two brackets respectively, the outer bottom of the square block is fitted with the bottom of the inner wall of the bracket. Then, the handle drives the screw to rotate to the right through the square plate. The rotating screw drives the straight plate to move to the right. The moving straight plate drives the round rod to slide in the inclined groove above the outer wall of the bracket. Since the bracket is slidably connected to the top plate, in order to ensure the movement balance of the bracket when the round rod moves to the right, the bracket will move upward through the top plate. The bracket drives the square block to move upward, making the top of the square block abut against the bottom of the top plate, changing the original control form, reducing the use difficulty of the liquid level sensor control device, and improving the working efficiency of the liquid level sensor control device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present utility model will be further described below with reference to the accompanying drawings: Embodiment 1

[0020] Please refer to Figures 1-5 : In this embodiment, a liquid level sensor control device includes a top plate 1 and a vertical plate 5. The left end of the top of the top plate 1 is fixedly connected to the bottom of the vertical plate 5. The right end of the top of the top plate 1 is fixedly connected to a square plate 4. A fixing structure 2 is connected to the inner wall of the square plate 4. A square block 7 is connected to the inner wall of the fixing structure 2. The front of the bottom of the top plate 1 is fixedly connected to a vertical plate 6. A control structure 3 is connected to the outer wall of the vertical plate 6.

[0021] The fixing structure 2 includes a screw 201 and a handle 202. The outer wall of the screw 201 is threadedly connected to the inner wall of the square plate 4. The screw 201 rotates left and right through the inner wall of the square plate 4 under force. The right side of the screw 201 is fixedly connected to the left side of the handle 202. The handle 202 facilitates driving the screw 201 to rotate. The left side of the outer wall of the screw 201 is rotatably connected to a straight plate 203. The top of the straight plate 203 is fixedly connected to a round rod 204. The end of the outer wall of the round rod 204 is slidably connected to a bracket 205. The outer wall of the bracket 205 is slidably connected to the top notch of the top plate 1. The bracket 205 moves up and down through the top notch of the top plate 1 under force. The inner wall of the bracket 205 is inserted into the outer end of the square block 7;

[0022] By inserting the front and rear ends of the outer wall of the square block 7 in the fixing structure 2 into the inner walls of the two brackets 205 respectively, the bottom outer side of the square block 7 is fitted to the bottom of the inner wall of the bracket 205. Then, the handle 202 drives the screw 201 to rotate to the right through the square plate 4. The rotating screw 201 drives the straight plate 203 to move to the right. The moving straight plate 203 drives the round rod 204 to slide in the inclined slot above the outer wall of the bracket 205. Since the bracket 205 is slidably connected to the top plate 1, in order to ensure the movement balance of the bracket 205 when the round rod 204 moves to the right, the bracket 205 will move upward through the top plate 1. The bracket 205 drives the square block 7 to move upward, so that the top of the square block 7 abuts against the bottom of the top plate 1, changing the original control form, reducing the use difficulty of the liquid level sensor control device, and improving the working efficiency of the liquid level sensor control device.

[0023] A liquid level sensor 8 is fixedly connected to the bottom of the square block 7. How to operate and use the liquid level sensor 8 is already prior art and will not be elaborated much. The model is selected according to the use requirements. The control structure 3 includes a cross plate 301 and a curved plate 302. The left ends of the inner sides of the two cross plates 301 are respectively fixedly connected to the front and rear sides of the vertical plate 6. The right end of the inner side of the cross plate 301 is rotatably connected to the upper part of the outer wall of the curved plate 302. The upper part of the outer wall of the curved plate 302 rotates through the pin shaft on the inner wall of the cross plate 301 under force. A bolt 303 is threadedly connected to the lower right side of the curved plate 302. The left side of the outer wall of the bolt 303 is threadedly connected to the right side of the vertical plate 6.

[0024] Working principle:

[0025] Installation of the liquid level sensor control device:

[0026] Press the left side of the vertical plate 5 against the connecting wall, then screw the screw thread through the vertical plate 5 from right to left and fix it to the wall by threading. Then tilt the square block 7 so that the front and rear ends of the outer wall of the square block 7 are inserted into the inner walls of the two brackets 205 respectively, and the outer bottom of the square block 7 is pressed against the bottom of the inner wall of the bracket 205. Then turn the handle 202 with the screw rod 201 to the right through the square plate 4. The rotating screw rod 201 drives the straight plate 203 to move to the right, and the moving straight plate 203 drives the round rod 204 to slide in the inclined groove above the outer wall of the bracket 205. Since the bracket 205 is slidably connected to the top plate 1, in order to ensure the movement balance of the bracket 205 when the round rod 204 moves to the right, the bracket 205 will move upward through the top plate 1. The bracket 205 drives the square block 7 to move upward, so that the top of the square block 7 is pressed against the bottom of the top plate 1.

[0027] The liquid level sensor control device controls the wire:

[0028] Rotate the curved plate 302 upward through the inner pin shaft of the cross plate 301. Then press the wire on the outer wall of the liquid level sensor 8 against the right side of the vertical plate 6. Then rotate the curved plate 302 downward so that the curved plate 302 covers the wire inside. Then screw the bolt 303 through the curved plate 302 from right to left and thread it into the round opening below the right side of the vertical plate 6 to complete the positioning of the wire. The output end of the activated liquid level sensor 8 monitors the liquid level of the liquid. Embodiment 2

[0029] Please refer to Figures 1-5 : In this embodiment, a liquid level sensor control device further includes a cushion 9, and the right side of the cushion 9 is attached to the left side of the vertical plate 5.

[0030] Working principle:

[0031] When the connection position is afraid of wear, press the right side of the cushion 9 against the left side of the vertical plate 5, and then sandwich the cushion 9 between the connection and the vertical plate 5. The rubber material of the cushion 9 itself plays a cushioning role to prevent the vertical plate 5 from wearing the connection.
