TECHNICAL FIELD

[0001] The application relates to the technical field of condensate water recovery equipment, and in particular to an adjustable liquid level sensing condensate water recovery storage tank. BACKGROUND

[0002] A large amount of condensate water is generated when an air conditioning system is working, and the condensate water generated by some traditional air conditioning systems is directly discharged through a condensate water pipe, which is not utilized and causes obvious energy waste. Therefore, a condensate water recovery and utilization system is generally used to recover and utilize the condensate water generated when the air conditioning system is working.

[0003] In the related art, reference can be made to the Chinese patent for invention with the authorized announcement number CN113007890A, which discloses a central air conditioning condensate water recovery and utilization system, comprising: a fresh air unit for sending the air extracted from outdoors to indoors after processing; a heat exchanger for heat exchanging the air extracted by the fresh air unit; a first storage tank for collecting and storing the condensate water flowing out of the heat exchanger, a flow combiner being arranged between the first storage tank and the heat exchanger; a first refrigerating machine for cooling the condensate water delivered in the first storage tank, a flow divider being arranged between the first refrigerating machine and the first storage tank; a second storage tank for collecting and storing the condensate water and delivering the condensate water to the heat exchanger; and a third storage tank for storing hot water, the third storage tank being provided with a first water inlet, a second water inlet and a water outlet, wherein the first water inlet is connected with the first storage tank, the second water inlet is connected with a fourth storage tank through a water pipe, and the water outlet is connected with the first refrigerating machine.

[0004] The liquid level sensors are arranged on the storage tanks in the condensate water recovery and utilization system, and the liquid level sensors are easily damaged due to being arranged in the storage tanks and being in contact with the liquid in the storage tanks for a long time, and the liquid level sensors need to be replaced and repaired by opening the storage tanks and entering the inside of the storage tanks, which is very inconvenient. CONTENT OF THE UTILITY MODEL

[0005] In order to improve the service life of the liquid level sensor and reduce the working intensity when the liquid level sensor is replaced and repaired, the application provides an adjustable liquid level sensing condensate water recovery storage tank.

[0007] The application provides an adjustable liquid level sensing condensate water recovery storage tank, which adopts the following technical scheme:

[0008] A casing is connected to the outer side wall of the tank through a mounting mechanism;

[0009] An infrared photoelectric emitter is arranged on the casing and abuts against the observation window, and the infrared photoelectric emitter emits infrared light to the inside of the tank.

[0010] An infrared signal receiver is arranged on the casing and is used to receive the infrared light reflected from the observation window.

[0011] A buzzer is arranged on the casing and is electrically connected to the infrared signal receiver.

[0012] By using the above technical scheme, the liquid level sensor can be detachably mounted to the outer side wall of the tank through the mounting mechanism, so that the liquid level sensor does not need to be in contact with the liquid in the tank, greatly improving the service life of the liquid level sensor, and making the liquid level sensor applicable to tanks containing various different liquids, thereby expanding the use range of the tank. When the liquid level sensor needs to be repaired or replaced, the liquid level sensor can be directly detached through the mounting mechanism, which is convenient, fast and high in work efficiency. The liquid level sensor emits infrared light to the inside of the tank through the glass observation window by the infrared photoelectric emitter. When there is liquid in the tank, the infrared light will be refracted in the liquid. At this time, the infrared signal receiver cannot receive the infrared signal, and the buzzer will not be triggered. When the liquid in the tank is consumed and the liquid surface is lower than the position of the infrared photoelectric emitter, the infrared light emitted by the infrared photoelectric emitter will bounce off the inner side wall of the tank and bounce back from the observation window. The infrared signal receiver receives the bounced-back infrared signal. After the infrared signal receiver receives the infrared signal, the buzzer is triggered to alarm, thereby reminding the staff to timely process the liquid state in the tank, thereby completing the sensing of the liquid level in the tank.

[0017] Optionally, the limiting assembly comprises:

[0018] The first limiting plate and the second limiting plate are arranged on the first mounting half ring and the second mounting half ring respectively, and the first limiting plate and the second limiting plate abut against each other when the first mounting half ring and the second mounting half ring are closed;

[0019] The limiting screw is sequentially threaded through the limiting holes in the first limiting plate and the second limiting plate;

[0021] By adopting the above technical scheme, when the first mounting half ring and the second mounting half ring cooperatively embrace the box body, the first limiting plate and the second limiting plate abut against each other, then the limiting screw is moved horizontally through the limiting holes in the first limiting plate and the second limiting plate, and the limiting nut is screwed to abut against the second limiting plate, so that the position fixing work of the first mounting half ring and the second mounting half ring when closed is completed.

[0022] Optionally, the shell is provided with a mounting cavity, the shell is slidably provided with a mounting block, the infrared photoelectric emitter, the infrared signal receiver and the buzzer are integrally arranged on the mounting block, and the shell is provided with a fixing mechanism for fixing the position of the mounting block in the mounting cavity.

[0028] By adopting the above technical scheme, the fixed elastic block is compressed and moved under the action of the fixed spring by pushing the push rod, so that the fixed elastic block is moved into the sliding slot, and then the mounting block is moved into the mounting cavity. When the position of the sliding slot is aligned with the position of the fixed hole, the fixed elastic block is partially penetrated out of the sliding slot and is inserted and matched with the fixed hole under the action of the fixed spring, so that the position fixing work of the mounting block in the mounting cavity is completed.

DETAILED DESCRIPTION

[0040] The following will be described in detail with reference to the accompanying drawings Figure 1 - the accompanying drawings Figure 2 The present application will be further described in detail.

[0041] The present application discloses a liquid level sensing condensate water recovery water storage tank.

[0042] Reference Figure 1The adjustable liquid level sensing condensate water recovery storage tank comprises a tank body 1, an installation mechanism 2 is arranged on the outer side wall of the tank body 1, and a liquid level sensor 11 is detachably installed on the tank body 1 through the installation mechanism 2.

[0043] With reference to Figure 1 The liquid level sensor 11 comprises a casing 12, an infrared photoelectric emitter 13, an infrared signal receiver 14 and a buzzer 15 arranged on the casing 12. The casing 12 is connected to the outer side wall of the tank body 1 through the installation mechanism 2. A horizontal installation cavity 16 is formed in the casing 12. An installation block 17 is slidably installed on the casing 12 and located in the installation cavity 16. The infrared photoelectric emitter 13, the infrared signal receiver 14 and the buzzer 15 are arranged on the installation block 17.

[0044] With reference to Figure 1 An observation hole is formed in the outer side wall of the tank body 1, and an observation window made of transparent glass material is fixedly installed on the observation hole of the tank body 1. The infrared photoelectric emitter 13 is in contact with the observation window and is used for emitting infrared light into the tank body 1. The infrared signal receiver 14 is fixedly installed on the installation block 17 and is used for receiving the infrared light reflected from the observation window. The buzzer 15 is fixedly installed on the installation block 17 and is electrically connected with the infrared signal receiver 14.

[0045] With reference to Figure 1 The infrared photoelectric emitter 13 emits infrared light into the tank body 1 through the glass observation window. When there is liquid in the tank body 1, the infrared light is refracted in the liquid. At this time, the infrared signal receiver 14 cannot receive the infrared signal, and the buzzer 15 cannot be triggered. When the liquid in the tank body 1 is consumed and the liquid level is lower than the position of the infrared photoelectric emitter 13, the infrared light emitted by the infrared photoelectric emitter 13 is bounced back from the inner side wall of the tank body 1 and is reflected from the observation window. The infrared signal receiver 14 receives the reflected infrared signal. After the infrared signal receiver 14 receives the infrared signal, the buzzer 15 is triggered to alarm, so as to remind the staff to timely process the liquid state in the tank body 1, thereby completing the sensing work of the liquid level in the tank body 1.

[0046] With reference to Figure 2The fixing mechanism 3 is arranged on the shell 12 and is used for fixing the position of the mounting block 17 in the mounting cavity 16. The fixing mechanism 3 comprises a fixing elastic block 31, a fixing spring 32 and a push rod 33. A horizontal sliding groove 34 is arranged on the outer side wall of the mounting block 17. The fixing elastic block 31 is slidably arranged on the mounting block 17 and located in the sliding groove 34. A fixing hole corresponding to the sliding groove 34 is arranged on the inner side wall of the mounting cavity 16 of the shell 12. The fixing spring 32 is fixedly arranged on the bottom wall of the sliding groove 34 and connected with the fixing elastic block 31, and the fixing elastic block 31 partially penetrates out of the sliding groove 34 and is in plug-in cooperation with the fixing hole under the action of the fixing spring 32. An arc-shaped guide surface 35 is arranged on the side wall of the shell 12 away from the opening of the mounting cavity 16 and the part of the fixing elastic block 31 penetrating out of the sliding groove 34. A moving hole is arranged on the outer side wall of the mounting block 17 along the moving direction of the fixing elastic block 31 and communicates with the sliding groove 34. The push rod 33 is slidably arranged in the moving hole. One end of the push rod 33 is located outside the mounting block 17, and the other end of the push rod 33 extends into the sliding groove 34 and is connected with the fixing elastic block 31.

[0047] With reference to Figure 2 The push rod 33 drives the fixing elastic block 31 to compress the fixing spring 32 and move, so that the fixing elastic block 31 moves into the sliding groove 34 as a whole, and then the fixing elastic block 31 is separated from the fixing hole, and the mounting block 17 can be taken out of the mounting cavity 16. When it is needed to install the mounting block 17, the mounting block 17 is moved into the mounting cavity 16, the guide surface 35 on the fixing elastic block 31 first contacts the outer side wall of the shell 12, the guide surface 35 generates a driving force for moving the fixing elastic block 31 into the sliding groove 34, so that the mounting block 17 moves into the mounting cavity 16, and when the position of the sliding groove 34 is aligned with the position of the fixing hole, the fixing elastic block 31 partially penetrates out of the sliding groove 34 and is in plug-in cooperation with the fixing hole under the action of the fixing spring 32, so that the fixing of the mounting block 17 in the mounting cavity 16 is completed.

[0048] With reference to Figure 1 And Figure 2 The shell 12 is detachably connected to the outer side wall of the box body 1 through the mounting mechanism 2. The mounting mechanism 2 comprises a first mounting half ring 21, a second mounting half ring 22 and a limiting assembly 23. The first mounting half ring 21 and the second mounting half ring 22 are both rotatably arranged on the shell 12 and clamp the outer side wall of the box body 1 in cooperation. Anti-skid lines 28 are arranged on the inner ring walls of the first mounting half ring 21 and the second mounting half ring 22. The limiting assembly 23 is arranged on the first mounting half ring 21 and the second mounting half ring 22 and is used for limiting the first mounting half ring 21 and the second mounting half ring 22 when the first mounting half ring 21 and the second mounting half ring 22 are closed.

[0049] With reference to Figure 1 And Figure 2The limiting assembly 23 comprises a first limiting plate 24, a second limiting plate 25, a limiting screw 26 and a limiting nut 27. The first limiting plate 24 and the second limiting plate 25 are fixedly installed at the ends of the first mounting half ring 21 and the second mounting half ring 22 respectively. When the first mounting half ring 21 and the second mounting half ring 22 are closed, the first limiting plate 24 and the second limiting plate 25 abut against each other. Limiting holes are formed in the first limiting plate 24 and the second limiting plate 25. The limiting screw 26 passes through the limiting holes in the first limiting plate 24 and the second limiting plate 25 in sequence. The limiting nut 27 is threadedly connected to the limiting screw 26 and abuts against the second limiting plate 25.

[0050] With reference to Figure 1 and Figure 2 When the first mounting half ring 21 and the second mounting half ring 22 are engaged to hold the tank 1, the first limiting plate 24 and the second limiting plate 25 abut against each other, then the limiting screw 26 is moved horizontally through the limiting holes in the first limiting plate 24 and the second limiting plate 25, and the limiting nut 27 is screwed to abut against the second limiting plate 25, thereby completing the fixing of the position of the first mounting half ring 21 and the second mounting half ring 22 when closed.

[0051] The working principle of the embodiment is as follows:

[0052] The liquid level sensor 11 is detachably mounted outside the tank 1 through the casing 12 and the first mounting half ring 21 and the second mounting half ring 22, so that the liquid level sensor 11 does not need to be in contact with the liquid in the tank 1, greatly improving the service life of the liquid level sensor 11, and enabling the liquid level sensor 11 to be applicable to the tank 1 containing various different liquids, thereby expanding the use range of the tank 1.

[0053] When the liquid level sensor 11 needs to be repaired or replaced, the liquid level sensor 11 can be directly detached by moving the mounting block 17 away through the lever 33, which is convenient, fast and high in working efficiency.

[0054] The liquid level sensor 11 emits infrared rays to the inside of the tank 1 through the glass observation window by the infrared photoelectric emitter 13. When there is liquid in the tank 1, the infrared rays will be refracted in the liquid. At this time, the infrared signal receiver 14 cannot receive the infrared signal, and the buzzer 15 will not be triggered. When the liquid in the tank 1 is consumed and the liquid surface is lower than the position of the infrared photoelectric emitter 13, the infrared rays emitted by the infrared photoelectric emitter 13 will rebound from the observation window after being reflected by the inner side wall of the tank 1. The infrared signal receiver 14 receives the rebounded infrared signal. After the infrared signal receiver 14 receives the infrared signal, the buzzer 15 is triggered to alarm, so as to remind the staff to timely process the liquid state in the tank 1, thereby completing the sensing work of the liquid surface in the tank 1.

[0055] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
