Description

Technical Field

[0001] The utility model relates to the field of water tank liquid level monitoring, in particular to a water tank liquid level monitoring device. Background Art

[0002] A water tank is a device used to hold water. It is divided into six types according to its material: FRP water tank, stainless steel water tank, stainless steel liner FRP water tank, seawater FRP water tank, enamel water tank, and galvanized steel plate water tank. In production and life, it is often necessary to store water in advance for backup or to quickly provide water when a large amount of water is used. In order to monitor the water level inside the water tank and replenish water when the water level is too low, the water tank is equipped with a special liquid level monitoring device. The monitoring instruments that are widely used now are mostly immersion static pressure level gauges.

[0003] However, the traditional immersion static pressure level instrument still has certain shortcomings during use: first, when replenishing or using water through the water tank, the current immersion level meter is prone to rocking back and forth and shifting sideways in the water tank, affecting the accuracy of monitoring, and also colliding with the inner wall of the water tank, causing damage to internal components; secondly, when the water tank is in use, if the outside ambient temperature is low, the water tank will freeze near the side walls and the upper and lower walls, and if the immersion level meter is directly thrown in too close to the outside, it will be frozen, causing losses. The current immersion level meter is not convenient to be fixed to a suitable position in the water tank for long-term and effective monitoring, and it is not convenient to take it out regularly for maintenance.

[0004] Therefore, it is necessary to provide a new water tank liquid level monitoring device to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a water tank liquid level monitoring device which can conveniently fix a drop-in static pressure liquid level gauge to a suitable position in a water tank, conveniently take it out for regular maintenance and can prevent the liquid level gauge from lateral displacement and shaking in the water tank.

[0006] In order to solve the above technical problems, the utility model provides a water tank liquid level monitoring device comprising: a box body, the top inner wall of the box body is connected to a mounting plate by bolts, the bottom surface of the mounting plate is vertically provided with a connecting plate, the surface of the connecting plate is rotatably connected with a transverse axis, one end of the transverse axis is fixedly connected with a worm gear, a worm is meshed with a worm at one side of the worm gear, the transverse axis is fixedly connected with a wire wheel relative to one end of the worm gear, the bottom of the connecting plate is fixedly connected with a track by a connecting block, the surface of the track is slidably connected with a slider, the surface of the slider is vertically provided with an ear plate, and the top surface of the ear plate is fixedly connected with a limiting bolt. The outer surface of the limit bolt is rotatably connected to a rotating plate, and the surface of the limit bolt located on the upper side of the rotating plate is threadedly connected to a tightening nut, and the end of the rotating plate is welded to a sliding frame, and an upper and lower sides of the sliding frame are respectively provided with an upper clamping plate and a lower clamping plate, and the top surface of the lower clamping plate is rotatably connected to a vertical screw, and the vertical screw is threadedly connected to the upper clamping plate, and a side wall surface of the lower clamping plate is connected to the vertical plate, and a fixing block is welded to the side wall surface of the vertical plate, and an installation groove is opened inside the fixing block, and a side wall surface of the fixing block is threadedly connected to a cross screw, and the end of the cross screw extends to the inside of the mounting groove and is fixedly connected to a pressure plate.

[0007] As a further solution of the utility model, a static pressure level gauge is arranged inside the installation groove, a protective pad is bonded to the surface of the pressure plate, and the protective pad abuts against the surface of the static pressure level gauge.

[0008] Through the above technical scheme, when installing the liquid level monitoring device, the mounting plate should be installed on the inner wall of the box on one side of the top cover, so that it is convenient to take out the instrument for maintenance in the later stage, and then the static pressure level gauge is inserted into the fixed block and the horizontal screw is rotated to lock the static pressure level gauge with the pressure plate at its end, and then the turntable is rotated to drive the wire wheel to rotate through the cooperation of the worm and the worm gear, so that the static pressure level gauge can be lowered to a suitable height, but the static pressure level gauge should not be allowed to touch the bottom, firstly to prevent the bottom scale and settled impurities from affecting the normal operation of the instrument, and secondly to avoid the low external ambient temperature causing the instrument to freeze. Since the static pressure level gauge is fixed on one side of the slider, the instrument will not move sideways when replenishing water and using water later, and will not hinder the normal monitoring work. At the same time, it can avoid hitting the inner wall of the box and being damaged. When it needs to be taken out to clean the filter inside the static pressure level gauge or to inspect it, it only needs to rotate the turntable in the opposite direction. The structural design facilitates its maintenance.

[0009] As a further solution of the utility model, the surface of the vertical plate located at the lower side of the fixing block is fixedly connected to the filter cartridge via a connecting block, and the bottom of the static pressure level gauge extends to the inner side of the filter cartridge.

[0010] Through the above technical solution, a general static pressure level gauge is also provided with a filter screen inside, but the long-term use of water inside the box easily produces more scale and sedimentation impurities. In order to ensure that the instrument can work stably for a long time, a filter cartridge is installed on the outside of the device for double protection.

[0011] As a further solution of the utility model, the top of the sliding block is fixedly connected to a pull ring through a connecting block, and a suspension rope is fixedly connected between the pull ring and the wire wheel.

[0012] Through the above technical solution, the slider and the reel are connected by a suspension rope. Due to the self-locking characteristics of the worm wheel and the worm, the user can adjust the slider to any height by rotating the turntable, which is convenient for the user to take it out for maintenance later.

[0013] As a further solution of the utility model, a turntable is fixedly connected to one end portion of the worm, and a handle is vertically arranged on the edge of the surface of the turntable.

[0014] Through the above technical solution, the turntable can be driven to rotate through the handle, so that the user can operate the line wheel through the cooperation of the worm wheel and the worm to make the line wheel reel in or out.

[0015] As a further solution of the utility model, a top cover is connected to one side of the top of the box body through a hinge, a ladder is fixedly connected to the surface of the box body located on one side of the top cover, and a base is fixedly connected to the bottom surfaces of the front and rear sides of the box body, and a threaded hole is opened on the surface of the base.

[0016] Through the above technical solution, workers can climb to the top of the box by climbing a ladder, then open the top cover and perform corresponding operations on the liquid level monitoring device inside. The structural design is convenient for workers to work.

[0017] As a further solution of the utility model, the front wall and the rear wall surfaces of the box body are respectively provided with water pipes and water supply pipes.

[0018] Through the above technical solution, when the static pressure level gauge detects that the amount of water inside the box is too little, it will open the external valve to introduce water into the water supply pipe to replenish the box, while the water pipe is convenient for users to take water as needed.

[0019] Compared with the related art, the water tank liquid level monitoring device provided by the utility model has the following beneficial effects:

[0020] 1. In the utility model, when installing the liquid level monitoring device, the mounting plate should be installed on the inner wall of the box on one side of the top cover, so that it is convenient to take out the instrument for maintenance in the later stage, and then insert the static pressure level gauge into the fixed block and rotate the horizontal screw to lock the static pressure level gauge with the pressure plate at its end, and then rotate the turntable to drive the wire wheel to rotate through the cooperation of the worm and the worm gear, so that the static pressure level gauge can be lowered to a suitable height, but the static pressure level gauge should not be allowed to touch the bottom, so as to prevent the bottom scale and settled impurities from affecting the normal operation of the instrument, and to prevent the instrument from being frozen due to the low external ambient temperature. Since the static pressure level gauge is fixed on one side of the slider, the instrument will not move sideways when replenishing water and using water later, and will not hinder the normal monitoring work. At the same time, it can avoid hitting the inner wall of the box and being damaged. When it needs to be taken out to clean the filter inside the static pressure level gauge or to overhaul it, it only needs to rotate the turntable in the opposite direction. The structural design is convenient for its maintenance;

[0021] 2. In the utility model, when the device is installed on one side of the top cover, in order to prevent the static pressure level gauge from being too close to the outside of the tank body, the user can rotate the direction of the rotating plate, and then fix the rotating plate with a tightening cap, and then use the cooperation of the vertical screw, the upper clamping plate and the lower clamping plate to fix the instrument at a suitable position on the sliding frame. Therefore, when facing various types of water tanks with different top cover positions, the liquid level monitoring device can keep the static pressure level gauge away from the edge of the tank body, ensuring that the structure can operate normally and continuously under low external ambient temperature.

[0032] When installing the liquid level monitoring device, the mounting plate 7 should be installed on the inner wall of the box body 1 on one side of the top cover 6, so that it is convenient to take out the instrument for maintenance later. Then, the static pressure level gauge 18 is inserted into the fixed block 21 and the horizontal screw 19 is rotated to lock the static pressure level gauge 18 with the pressure plate 20 at its end. Then, the turntable 9 is rotated to drive the wire wheel 8 to rotate through the cooperation of the worm 17 and the worm wheel 16, so that the static pressure level gauge 18 can be lowered to a suitable height, but the static pressure level gauge 18 should not be allowed to touch the bottom, so as to prevent the bottom scale and settled impurities from affecting the normal operation of the instrument, and to prevent the instrument from being frozen due to the low external ambient temperature. Since the static pressure level gauge 18 is fixed on one side of the slider 13, the instrument will not move sideways when replenishing water and using water later, and will not hinder the normal monitoring work. At the same time, it will avoid hitting the inner wall of the box body 1 and being damaged. When it needs to be taken out to clean the filter inside the static pressure level gauge 18 or to overhaul it, it only needs to rotate the turntable 9 in the opposite direction. The structural design facilitates its maintenance.

[0033] like Figure 1 As shown, the surface of the vertical plate 29 located at the lower side of the fixing block 21 is fixedly connected to the filter cartridge 11 through a connecting block, and the bottom of the static pressure level gauge 18 extends to the inner side of the filter cartridge 11 .

[0035] like Figure 1 As shown, a pull ring 25 is fixedly connected to the top of the slider 13 via a connecting block, and a suspension rope 12 is fixedly connected between the pull ring 25 and the wire wheel 8.

[0036] The slider 13 and the reel 8 are connected by a suspension rope 12. Due to the self-locking characteristics of the worm wheel 16 and the worm 17, the user can adjust the slider 13 to any height by rotating the turntable 9, which is convenient for the user to take it out for maintenance later.

[0037] like Figure 1 As shown, one end of the worm 17 is fixedly connected to a turntable 9, and a handle is vertically provided at the edge of the surface of the turntable 9.

[0038] The turntable 9 can be driven to rotate by the handle, so that the user can operate the line wheel 8 through the cooperation of the worm wheel 16 and the worm 17 to make the line wheel 8 reel in or reel out the line.

[0039] like Figure 1As shown, a top cover 6 is connected to one side of the top of the box body 1 through a hinge, a ladder 3 is fixedly connected to the surface of the box body 1 located on one side of the top cover 6, and a base 2 is fixedly connected to the bottom surfaces of the front and rear sides of the box body 1, and a threaded hole is opened on the surface of the base 2.

[0040] The top of the box body 1 can be climbed to by the ladder 3, and then the top cover 6 can be opened to perform corresponding operations on the liquid level monitoring device inside. The structural design is convenient for workers to work.

[0041] like Figure 1 As shown, the front wall and rear wall surfaces of the box body 1 are respectively provided with a water pipe 4 and a water supply pipe 5.

[0042] When the static pressure level gauge 18 detects that the amount of water inside the box 1 is too little, it will open the external valve to introduce water into the water supply pipe 5 to replenish the box 1, while the water pipe 4 is convenient for users to take water as needed.

[0043] The working principle of a water tank liquid level monitoring device provided by the utility model is as follows:

[0044] The first step: when installing the liquid level monitoring device, the mounting plate 7 should be installed on the inner wall of the box body 1 on one side of the top cover 6, so that it is convenient to take out the instrument for later maintenance. Then, the static pressure level gauge 18 is inserted into the fixed block 21 and the horizontal screw 19 is rotated to lock the static pressure level gauge 18 with the pressure plate 20 at its end. Then, the turntable 9 is rotated to drive the wire wheel 8 to rotate through the cooperation of the worm 17 and the worm wheel 16, so that the static pressure level gauge 18 can be lowered to a suitable height, but the static pressure level gauge 18 should not be allowed to touch the static pressure level gauge 18. The static pressure level gauge 18 is fixed on one side of the slider 13, so when water is replenished or used later, the instrument will not move sideways, which will not hinder the normal monitoring work. At the same time, it can avoid hitting the inner wall of the box 1 and being damaged. When the filter screen inside the static pressure level gauge 18 needs to be taken out to clean or repair it, it only needs to rotate the turntable 9 in the opposite direction. The structural design is convenient for its maintenance.

[0045] The second step: when the device is installed on one side of the top cover 6, in order to prevent the static pressure level gauge 18 from being too close to the outside of the box body 1, the user can rotate the direction of the rotating plate 27, and then use the tightening cap 26 to fix the rotating plate 27, and then use the vertical screw 22, the upper clamping plate 15 and the lower clamping plate 23 to fix the instrument at a suitable position on the sliding frame 14. Therefore, when facing various types of water tanks with different positions of the top cover 6, the liquid level monitoring device can keep the static pressure level gauge 18 away from the edge of the box body 1, ensuring that the structure can operate normally and continuously under low external ambient temperature.
