Description

Technical Field

[0001] The utility model belongs to the technical field of aquaculture, and in particular relates to a heat exchanger lifting and lowering regulating device. Background Art

[0002] With the growth of breeding technology, aquaculture has shifted from extensive to intensive development. Intensification requires a controllable breeding environment. As one of the necessary conditions for breeding organisms, rapid response of temperature regulation is of great value to aquaculture applications.

[0003] At present, heat exchangers are generally placed inside pond water to achieve heat exchange in order to effectively control the ambient temperature of the water body; however, in actual use, the liquid level of the water body often changes, and at this time the position of the heat exchanger in the water body needs to be adjusted for adaptation.

[0004] In the prior art, workers usually manually adjust the position of the heat exchanger, which makes it difficult to control the placement depth of the heat exchanger. If the heat exchanger is placed too deep, it may cause the heat exchanger to contact the mud at the bottom of the pool. If it is placed too shallow, the heat exchanger may be partially exposed outside the water body. Both situations will reduce the working efficiency of the heat exchanger and shorten the service life of the heat exchanger. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See attached Figure 1 -Attached Figure 4 A heat exchanger lifting and adjusting device comprises a heat exchange unit 1, a lifting unit 2 and a monitoring unit 3; the heat exchange unit 1 comprises a heat pump outdoor unit 11, a copper tube 12 and a heat exchanger 13, the heat pump outdoor unit 11 is installed outside the pond and connected to the heat exchanger 13 through the copper tube 12; the lifting unit 2 comprises an adjusting part 21 and a support rod 22, the support rod 22 is fixedly connected to the heat exchanger 13, the adjusting part 21 is installed outside the pond and connected to the support rod 22, and the adjusting part 21 can control the movement of the support rod 22 to adjust the height position of the heat exchanger 13; the monitoring unit 3 comprises a high-position sensor 31 and a middle-position sensor 32, the high-position sensor 31 is installed on the support rod 22 and is located above the heat exchanger 13, the middle-position sensor 32 is installed on the support rod 22 or the heat exchanger 13, and the middle-position sensor 32 is flush with the top of the heat exchanger 13.

[0025] Specifically, when in use, the support rod 22 is used to extend the heat exchanger 13 into the pond water body, and the water level is between the middle position sensor 32 and the high position sensor 31. Under the action of the middle position sensor 32, it can be ensured that the heat exchanger 13 is completely immersed in the water body, and under the action of the high position sensor 31, the heat exchanger 13 is prevented from being placed too deep and contacting the mud at the bottom of the pond.

[0026] During use, when the liquid level in the pond changes, if the water level is lower than the middle level sensor 32 or higher than the high level sensor 31, the middle level sensor 32 or the high level sensor 31 sends out a warning signal. At this time, the user can control the movement of the support rod 22 through the adjustment part 21 to readjust the height position of the heat exchanger 13 so that the water level is back between the middle level sensor 32 and the high level sensor 31.

[0027] In summary, the utility model designs a lifting unit 2 for adjusting the height position of the heat exchanger 13 and designs a monitoring unit 3 for monitoring the water level to prevent the heat exchanger 13 from being placed too deep or too shallow, thereby ensuring the working efficiency and service life of the heat exchanger 13.

[0028] See attached Figure 1 -Attached Figure 4 Considering that if the copper tube 12 is directly extended into the water body to connect to the heat exchanger 13, the copper tube 12 will be corroded and damaged by the water body. To solve this problem, in this embodiment, the support rod 22 is designed to be hollow inside, and the end of the copper tube 12 away from the heat pump outdoor unit 11 is connected to the support rod 22, and the copper tube 12 is connected to the heat exchanger 13 via the support rod 22.

[0029] Specifically, when the heat exchanger 13 is extended into the water body by the support rod 22, the copper tube 12 is located above the water level and provides coolant to the heat exchanger 13 through the support rod 22. This design can prevent the copper tube 12 from being directly extended into the water body and being corroded, thereby extending the service life of the copper tube 12.

[0030] See attached Figure 1 -Attached Figure 4 Considering that the water level may fluctuate during actual use, the copper tube 12 may still be corroded by water. To avoid this problem, in this embodiment, the connection point between the copper tube 12 and the support rod 22 is above the high-level sensor 31.

[0031] Specifically, when the high-level sensor 31 is below the water level, it will send out a warning signal, so that the user can move the support rod 22 in time to adjust the position of the heat exchanger 13. In the process of moving the support rod 22, the copper tube 12 will also be driven out of the water to prevent the copper tube 12 from being corroded by being immersed in water for a long time, thereby extending the service life of the copper tube 12.

[0032] See attached Figure 1 -Attached Figure 4 The types of the adjusting part 21 are various and relatively conventional in the mechanical field, such as a screw motor structure with a stroke, a telescopic structure, etc., which are not limited in the utility model; for the convenience of operation, in the present embodiment, the adjusting part 21 includes a fixed seat 211, a bottom rod 212 and a connecting rod 213; the fixed seat 211 is installed on the ground outside the pond, the bottom rod 212 is horizontally arranged on the fixed seat 211, the tail end of the connecting rod 213 is connected to the tail end of the bottom rod 212, and the connecting rod 213 extends upward at an angle; movable sleeves 214 are installed at the head end of the bottom rod 212 and the head end of the connecting rod 213, and the support rod 22 can slidably penetrate the two movable sleeves 214 to form a triangular structure between the support rod 22, the bottom rod 212 and the connecting rod 213, and the two movable sleeves 214 are threadedly connected with fastening bolts 215, and the fastening bolts 215 are turned to tighten or loosen the support rod 22.

[0033] Specifically, when in use, the fastening bolt 215 is turned to loosen the support rod 22, and the support rod 22 can be moved along the two movable sleeves 214, thereby adjusting the height position of the heat exchanger 13; after the support rod 22 is moved to a suitable position, the fastening bolt 215 is turned to tighten the support rod 22, so that the heat exchanger 13 can be fixed at the current position; since a triangular structure is formed between the support rod 22, the bottom rod 212 and the connecting rod 213, the structural stability is relatively strong.

[0034] See attached Figure 1 -Attached Figure 4 The monitoring unit 3 also includes a low-position sensor 33 , which is mounted on the support rod 22 or the heat exchanger 13 , and is located below the middle-position sensor 32 .

[0035] The added low-level sensor 33 is used in conjunction with the middle-level sensor 32 and the high-level sensor 31 to better monitor the water level, identify the operating status of each sensor, determine whether each water level and sensor is damaged, and enrich the alarm content, as follows:

[0036] 1. When the water level is between the high level sensor 31 and the middle level sensor 32, the water level is normal and no alarm is given, and no adjustment is required;

[0037] 2. When the water level is below the high-level sensor 31 and the middle-level sensor 32, the water level is abnormal and an alarm is given. At this time, tighten the fastening bolt 215 to loosen the support rod 22, and adjust the heat exchanger 13 downward until the water level is back between the high-level sensor 31 and the middle-level sensor 32, so that the water level is normal.

[0038] 3. When the water level is below the low-level sensor 33, the middle-level sensor 32 and the high-level sensor 31, the water level is abnormal and an alarm is given. At this time, tighten the fastening bolt 215 to loosen the support rod 22, and adjust the heat exchanger 13 downward until the water level is back between the high-level sensor 31 and the middle-level sensor 32, so that the water level is normal.

[0039] 4. When the water level is above the high-level sensor 31, the water level is abnormal and an alarm is given. At this time, tighten the fastening bolt 215 to loosen the support rod 22, and adjust the heat exchanger 13 upward until the water level is back between the high-level sensor 31 and the middle-level sensor 32, so that the water level is normal.

[0040] See attached Figure 1 -Attached Figure 4 The monitoring unit 3 also includes an alarm 34, which is arranged outside the pond and is electrically connected to the high-level sensor 31, the middle-level sensor 32 and the low-level sensor 33.

[0041] Among them, when the water level or sensor is abnormal, the high-level sensor 31, the middle-level sensor 32 and the low-level sensor 33 will transmit signals to the alarm 34, and the alarm 34 will play an alarm according to the signals sent by the high-level sensor 31, the middle-level sensor 32 and the low-level sensor 33. The specific alarm content is as follows:

[0042] Low water level sensor Water level sensor High water level sensor Siren Alert content State 1 disconnect disconnect disconnect closure Abnormal water level State 2 disconnect disconnect closure closure Abnormal water level State 3 disconnect closure disconnect closure Sensor abnormality State 4 disconnect closure closure closure Sensor abnormality State 5 closure disconnect disconnect closure Sensor abnormality State 6 closure disconnect closure closure Sensor abnormality Status 7 closure closure disconnect disconnect Water level normal State 8 closure closure closure closure Abnormal water level

[0043] Table 1

[0044] It should be noted that the alarm 34 generally adopts a sound unit such as a speaker, which is an existing product; in addition to the above structure, the monitoring unit 3 can send signals to signal receiving devices such as mobile phones and displays to facilitate users to view the alarm content, and this is not limited in the present utility model.

[0045] It should also be noted that, although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application.
