Technical Field

[0001] This utility model relates to the technical field of liquid level installation, specifically a liquid level installation structure applicable to various types of tanks. Background Technology

[0002] Pig farms are production sites that require ensuring the normal growth of pigs. Therefore, they need to be deodorized and sterilized. Spraying deodorizers inside the pigsty can effectively reduce the emission of harmful gases such as ammonia and improve the environment of the pigsty. However, the liquid level of the deodorizer needs to be monitored during use to avoid the influence of subjective human factors due to manual monitoring.

[0003] Existing liquid level installation structures suitable for various tanks require adjustment of the lower position of the liquid level tube according to the depth of the tank during use. However, after adjustment, it cannot be quickly snapped and fixed, resulting in poor flexibility. In addition, the liquid level gauges are directly installed on the hydraulic pipes without pretreatment, leading to a short service life and increased monitoring costs.

[0004] Therefore, we propose a liquid level installation structure applicable to various types of tanks to solve the problems mentioned above. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figure 1-7 A liquid level installation structure suitable for various types of tanks includes a tank body 1 and a bracket 2 fixedly installed on the top of the tank body 1 near the left side. An opening is provided on the top of the tank body 1 near the left side, and a corresponding circular opening is provided on the bracket 2. A positioning plate 3 is attached to the middle of the top of the bracket 2, and a liquid level pipe 4 is fixedly installed through the middle of the top of the positioning plate 3. The lower end of the liquid level pipe 4 passes through the opening and extends into the inner cavity of the tank body 1. Clamping components 5 are installed on the front and rear sides of the bracket 2, and several T-shaped pipes 6 are threaded onto the liquid level pipe 4. Insertion level gauges A7, B8, and C9 are threadedly installed in the inner cavity, and an internal threaded elbow 10 is threadedly installed at the lower end of the level tube 4. An insertion level gauge D20 is threadedly installed in the inner cavity of the internal threaded elbow 10. A signal line 30 is provided on the insertion level gauges A7, B8, C9, and D20. The outer end of the signal line 30 extends to the outside of the level tube 4 to monitor the liquid level in the tank 1. The snap-fit ​​assembly 5 is used to fix the level tube 4 to the tank 1.

[0029] Specifically, positioning holes 21 are provided at the top of the bracket 2 near the four corners.

[0030] Specifically, positioning rods 31 are fixedly installed at the bottom of the positioning plate 3 near the four corners, and the outer sides of the positioning rods 31 are slidably installed in the inner cavities of adjacent positioning holes 21. Slots 32 are opened at the middle of the front and rear sides of the positioning plate 3, and the outer side of the insert block 56 is inserted into the inner cavity of the rear slot 32, which serves as a guide and limit when the positioning plate 3 is placed, and at the same time facilitates the unfolding of the snap-fit ​​operation.

[0031] Specifically, a sealing plug 41 is fixedly sleeved on the outer side of the liquid level tube 4 near the top, and the sealing plug 41 is inserted into the inner cavity of the opening to seal the opening.

[0032] In this embodiment: During use, the insertion level gauges A7, B8, C9, and D20 are used to monitor the liquid level in tank 1. Because the built-in cables of the level gauges are relatively short, the signal line 30 is extended during the level gauge fabrication process. After splicing, the exposed copper length does not exceed 1.5cm. The splice is first completely wrapped with heat-shrink tubing, then completely covered with liquid insulating tape, applied evenly at least twice, with an interval of at least fifteen minutes between applications. The tape is allowed to dry completely before... Before assembly, the level gauge must be secured with insulating tape to prevent damage during installation. Remove the tape before installation. Wrap an appropriate amount of Teflon tape around the level gauge in a clockwise direction and connect it to the tee pipe 6 or the internal thread elbow 10. Tighten it one turn at a time, and do not tighten it all at once during installation to prevent wire tangling, which could cause the bottom of the level gauge to crack and leak copper. At the connection point between the water inlet / outlet connector of the level gauge 4 and the conduit, the conduit should be slightly lower than the water inlet of the water inlet / outlet connector. At the same time, wrap waterproof insulating tape around the connection to prevent water from flowing into the level gauge 4 along the conduit.

[0033] Example 2

[0034] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 1 and Figure 5-8 The snap-fit ​​assembly 5 includes an adjusting plate 51 located at the lower rear side of the bracket 2 and a threaded rod 52 threaded through and installed at the middle of the adjusting plate 51. The lower end of the threaded rod 52 is movably installed on the barrel 1, and a knob 53 is fixedly installed at the upper end of the threaded rod 52. A U-shaped plate 54 is fixedly installed on the top of the adjusting plate 51. A pull plate 55 is provided on the front side of the inner cavity of the U-shaped plate 54, and an insert block 56 is fixedly installed on the front side of the pull plate 55 near the top, which serves to snap-fit ​​the positioning plate 3 and also to install the liquid level pipe 4.

[0035] Specifically, a limiting telescopic rod 511 is fixedly installed at the bottom of the adjusting plate 51 near the left side, and the lower end of the limiting telescopic rod 511 is fixedly installed on the barrel 1, which serves to guide and limit the movement of the adjusting plate 51.

[0036] Specifically, pull rods 551 are fixedly installed on the rear side of the pull plate 55 near the left and right sides, and the rear ends of the pull rods 551 slide through and extend to the outside of the U-shaped plate 54, and are fixedly installed with pull rings 552, which facilitates the movement of the pull plate 55.

[0037] Specifically, sliding rods 541 are fixedly installed on the inner side of the U-shaped plate 54 near the left and right sides, and the front ends of the sliding rods 541 slide through and extend to the outer side of the pull plate 55. Return springs 542 are respectively sleeved on the outer side of the sliding rods 541. The front and rear ends of the return springs 542 are fixedly installed on the pull plate 55 and the U-shaped plate 54, which facilitates the movement and restoration of the pull plate 55.

[0038] In this embodiment: when the liquid level tube 4 enters the inner cavity of the barrel 1 through the circular opening and the through-hole, it will drive the positioning rod 31 to move downward through the positioning hole 21. Then, its low position can be adjusted as needed. After adjusting the position of the liquid level tube 4 in the barrel 1 to a suitable low position, the movement of the liquid level tube 4 can be stopped. In addition, after adjustment, the knobs 53 on the front and rear sides are turned, thereby driving the adjacent threaded rod 52 to rotate. When the threaded rod 52 rotates, it will drive the adjacent adjusting plate 51 to move. When it moves to a position that facilitates the insertion of the plug 56 into the inner cavity of the slot 32, the knob 53 can be stopped. At the same time, the pull ring 552 should be pulled to the opposite side, so that the pull plate 55 can be moved in the opposite direction through the pull rod 551, and the adjacent return spring 542 is squeezed at the same time. When the adjusting plate 51 moves to a suitable height, the pull ring 552 can be released, so that the plug 56 can be inserted into the inner cavity of the adjacent slot 32 under the action of the rebound force of the adjacent return spring 542, which plays a fixing role and has high flexibility.

[0039] Working principle: During use, the insertion level gauges A7, B8, C9, and D20 monitor the liquid level in tank 1. Because the built-in cables of the level gauges are relatively short, the signal line 30 is extended during the level gauge fabrication process. After splicing, the exposed copper length should not exceed 1.5cm. The splice joint is first completely wrapped with heat-shrink tubing, then completely covered with liquid insulating tape, applying at least two even coats. Allow at least fifteen minutes for complete drying before assembling and using. Before installation, secure the level gauge with insulating tape to prevent damage during installation. Remove the tape before installation. Wrap a suitable amount of Teflon tape clockwise around the level gauge and connect it to the tee pipe 6 or internal thread elbow 10. Tighten each turn gradually, avoiding tightening all at once to prevent wire tangling and potential cracking and copper leakage at the bottom of the level gauge. The connection point between the level gauge 4 inlet / outlet water connector and the conduit should be slightly lower than the top / bottom water inlet / outlet. The water inlet of the connector is wrapped with waterproof insulating tape to prevent water from flowing into the level tube 4 along the pipeline. When the level tube 4 enters the inner cavity of the tank 1 through the circular opening and the through-hole, it will drive the positioning rod 31 to move downward through the positioning hole 21. Then, its low position can be adjusted as needed. After adjusting the position of the level tube 4 in the tank 1 to a suitable low position, the movement of the level tube 4 can be stopped. In addition, after adjustment, the knobs 53 on the front and rear sides are turned, thereby driving the adjacent threaded rod 52 to rotate. When the threaded rod 52 rotates, it will drive... The adjacent adjusting plate 51 moves until it is easy for the insert 56 to be inserted into the inner cavity of the slot 32. Then the knob 53 can be stopped. At the same time, the pull ring 552 should be pulled to the opposite side. This will cause the pull plate 55 to move in the opposite direction through the pull rod 551, and at the same time squeeze the adjacent return spring 542. When the adjusting plate 51 moves to the appropriate height, the pull ring 552 can be released, so that the insert 56 can be inserted into the inner cavity of the adjacent slot 32 under the action of the rebound force of the adjacent return spring 542, thereby playing a fixing role.
