Abstract
Description
Technical Field
[0001] This utility model relates to the field of condensate drainage technology, and in particular to a heating, ventilation and air conditioning condensate drainage device. Background Technology
[0002] A condensate drain system is a collective term for a series of devices and components in an HVAC system used to collect, transport, and discharge condensate produced when air condenses upon cooling. In the current operation of HVAC systems, the stable operation of the condensate drain system is crucial for ensuring the safety of the indoor environment and equipment. Existing condensate drainers often use ordinary plug-in or simple binding methods when connecting water pipes to inlets. These connection methods are insufficient to withstand complex operating conditions. During system operation, the continuous impact of water flow, vibrations from equipment operation, or accidental pulling during routine maintenance can easily cause the connection between the water pipe and the inlet to loosen or detach. Once this occurs, it not only leads to condensate leakage, soaking interior decorations and damaging surrounding equipment, but also affects the normal operation of the HVAC system due to poor drainage, fostering bacterial growth and causing indoor air quality problems. Furthermore, the water pipes, when not effectively secured, are prone to shaking or shifting, easily rubbing against surrounding objects, accelerating pipe aging and damage, and increasing maintenance costs and frequency.
[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: the water pipe connected to the water inlet may become loose or fall off due to water flow impact, equipment vibration or external pulling, resulting in condensate leakage; therefore, a heating and ventilation condensate drainage device is proposed to address the above problems. Utility Model Content
[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, where the connection between the water pipe connected to the water inlet can become loose or fall off due to water flow impact, equipment vibration or external force pulling, resulting in condensate leakage. Therefore, a heating and ventilation condensate drainage device is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a heating and ventilation condensate drainage device, comprising a drainer, an inlet, and a outlet, wherein the surface of the drainer is provided with a clamping device, the clamping device comprising a fixing plate, the fixing plate being fixedly connected to the surface of the drainer, a threaded rod being threadedly inserted into the fixing plate, one end of the threaded rod being fixedly connected to a circular plate, the circular plate having a plurality of anti-slip grooves on its arc surface, a clamping plate being rotatably connected to the end of the threaded rod away from the circular plate, the clamping plate being semi-arc in shape, and a stop plate being fixedly connected to the surface of the drainer.
[0006] The aforementioned components achieve the following effects: by setting up a clamping device, the water pipe is firmly connected to the inlet, keeping the water pipe in a set position and preventing it from shaking or shifting at will. This prevents the connection between the water pipe and the inlet from loosening or falling off due to water flow impact, equipment vibration, or external pulling, thus preventing condensate leakage and ensuring the sealing and normal operation of the drainer.
[0007] Preferably, a fixing rod is slidably inserted into the fixing plate, and one end of the fixing rod is fixedly connected to the clamping plate.
[0008] The effect achieved by the above components is as follows: by setting the fixing rod, the clamping plate is precisely guided, the movement trajectory of the clamping plate is restricted, and it can only move in a straight line in a fixed direction, so as to prevent the clamping plate from shifting or rotating during the movement, thereby ensuring the stability of the clamping effect.
[0009] Preferably, the surface of the abutment is provided with a groove, and the groove is semi-circular in shape.
[0010] The effect achieved by the above-mentioned components is that by setting the slot, they can fit tightly against the outer surface of the water pipe, increasing the contact area with the water pipe and thus providing greater friction, which can significantly improve the clamping effect and adaptability of the water pipe.
[0011] Preferably, a sealing gasket is fixedly connected to the surface of the clamp, and the sealing gasket is made of rubber.
[0012] The effect achieved by the above components is that by setting a sealing gasket, the tiny gap between the clamp and the water pipe is filled, effectively preventing condensate from leaking out from the clamp and greatly enhancing the sealing performance of the device.
[0013] Preferably, the inner wall of the water inlet is provided with a filter device, the filter device includes a circular frame, the circular frame is fixedly connected to the inner wall of the water inlet, a filter plate is slidably connected to the surface of the circular frame, and a plurality of filter holes are opened on the surface of the filter plate.
[0014] The effects achieved by the above components are as follows: by setting up a filter device, it can effectively intercept dust, impurities, rust and other particles in the condensate, preventing them from entering the inside of the drain, avoiding pipe blockage, ensuring smooth discharge of condensate, extending the service life of the entire drain, reducing maintenance costs and frequency, and improving the cleanliness of the condensate.
[0015] Preferably, two limiting rods are slidably inserted into the water inlet, and the arc surfaces of the two limiting rods are slidably connected to the filter plate. One end of each limiting rod is fixedly connected to a connecting plate.
[0016] The effect achieved by the above components is that by setting the limit rod, the filter plate can be replaced and maintained, thus preventing the filter plate from accumulating a large amount of dust, impurities, rust and other pollutants as the usage time increases. When these pollutants accumulate to a certain extent, they will clog the filter holes and hinder the normal passage of condensate.
[0017] Preferably, the arc surface of the limiting rod is fitted with a spring, and the two ends of the spring are fixedly connected to the water inlet and the connecting plate, respectively.
[0018] The effect achieved by the above components is that, under the action of the spring, the elastic force of the spring pushes the limiting rod to automatically insert into the water inlet, and the filter plate is firmly fixed in the predetermined position, thereby improving the practicality of the device.

[0027] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, this utility model provides a technical solution: a heating and ventilation condensate drainage device, including a drainer 1, an inlet 2, and an outlet 3. The surface of the drainer 1 is provided with a clamping device 4. By setting the clamping device 4, the water pipe can be firmly connected to the inlet 2, keeping the water pipe in a set position and preventing the water pipe from shaking or shifting at will. This prevents the connection between the water pipe and the inlet 2 from loosening or falling off due to water flow impact, equipment vibration, or external pulling, thus preventing condensate leakage and ensuring the sealing and normal operation of the drainer 1. The inner wall of the inlet 2 is provided with a filter device 5. By setting the filter device 5, dust, impurities, rust, and other particles in the condensate can be effectively intercepted, preventing them from entering the interior of the drainer 1, avoiding pipe blockage, ensuring smooth discharge of condensate, extending the service life of the entire drainer 1, reducing maintenance costs and frequency, and improving the cleanliness of the condensate.
[0028] The specific setup and function of the clamping device 4 and the filtering device 5 will be explained in detail below.
[0029] Reference Figure 2 and Figure 3As shown in this embodiment: the clamping device 4 includes a fixed plate 41, which is fixedly connected to the surface of the drainer 1. A threaded rod 42 is threadedly inserted into the fixed plate 41. A circular plate 44 is fixedly connected to one end of the threaded rod 42. Several anti-slip grooves 45 are formed on the arc surface of the circular plate 44. A clamping plate 43 is rotatably connected to the end of the threaded rod 42 away from the circular plate 44. The clamping plate 43 is semi-arc in shape. A stop plate 46 is fixedly connected to the surface of the drainer 1. A fixed rod 47 is slidably inserted into the fixed plate 41. One end of the fixed rod 47 is fixedly connected to the clamping plate 43. By setting the fixed rod 47, the clamping plate 43 is precisely guided, and the movement trajectory of the clamping plate 43 is restricted, so that it can only move along the fixed... The linear movement of the clamping plate 43 prevents it from shifting or rotating during movement, thus ensuring the stability of the clamping effect. The surface of the abutment plate 46 is provided with a slot 48, which is semi-circular in shape. By setting the slot 48, it can fit tightly against the outer surface of the water pipe, increasing the contact area with the water pipe and thus providing greater friction. This significantly improves the clamping effect and adaptability of the water pipe. A sealing gasket 49 is fixedly connected to the surface of the clamping plate 43. The sealing gasket 49 is made of rubber. By setting the sealing gasket 49, the tiny gaps between the clamping plate 43 and the water pipe are filled, effectively preventing condensate from leaking from the clamping point and greatly enhancing the sealing performance of the device.
[0030] Reference Figure 4 and Figure 5 As shown, specifically, the filter device 5 includes a circular frame 51, which is fixedly connected to the inner wall of the inlet 2. A filter plate 52 is slidably connected to the surface of the circular frame 51. The surface of the filter plate 52 has several filter holes 53. Two limiting rods 54 are slidably inserted into the inlet 2. The arc surfaces of the two limiting rods 54 are slidably connected to the filter plate 52. One end of the limiting rod 54 is fixedly connected to a connecting plate 55. By setting the limiting rods 54, the filter plate 52 can be replaced and maintained, avoiding damage during use. As the filter plate 52 increases, it will intercept a large amount of dust, impurities, rust and other pollutants. When these pollutants accumulate to a certain extent, they will block the filter holes 53 and hinder the normal passage of condensate. The arc surface of the limiting rod 54 is fitted with a spring 56. The two ends of the spring 56 are fixedly connected to the water inlet 2 and the connecting plate 55 respectively. Under the action of the spring 56, the elastic force of the spring 56 pushes the limiting rod 54 to automatically insert into the water inlet 2 and makes the filter plate 52 firmly fixed in the predetermined position, which improves the practicality of the device.
[0031] Working principle: When the operator needs to clamp and secure the water pipe connected to the inlet 2, rotating the circular plate 44 causes the anti-slip groove 45 on the circular plate 44 to contact the operator's hand, increasing friction. The circular plate 44 drives the threaded rod 42 to rotate within the fixed plate 41, which in turn drives the clamping plate 43 and the sealing gasket 49 to move towards the water pipe. At this time, the fixed rod 47 slides within the fixed plate 41, moving towards the water pipe along with the clamping plate 43, thus restricting the movement trajectory of the clamping plate 43, ensuring it can only move linearly in a fixed direction and preventing it from shifting or rotating with the rotation of the threaded rod 42. Then, the clamping plate 43, along with the sealing gasket 49, comes into contact with the water pipe, pressing the water pipe against the slot 48 on the abutment plate 46. The semi-circular design of the slot 48 ensures a tight fit with the outer surface of the water pipe. The clamping device 4 is designed to fit the water pipe, thereby increasing the contact area with the water pipe and providing greater friction. At this time, after the clamping plate 43 and the water pipe are fitted together, the sealing gasket 49, with the softness and good elasticity of the rubber material, will fill the tiny gap between the clamping plate 43 and the water pipe, preventing condensate from leaking out from the clamping point. The clamping device 4 stops when the clamping plate 43 firmly presses the water pipe into the slot 48 of the abutment plate 46, thus completing the clamping and stabilizing of the water pipe. By setting the clamping device 4, the water pipe can be firmly connected to the inlet 2, keeping the water pipe in the set position and preventing the water pipe from shaking or shifting at will. This prevents the connection between the water pipe and the inlet 2 from loosening or falling off due to water flow impact, equipment vibration or external pulling, avoids condensate leakage, and ensures the sealing and normal operation of the drainer 1.
[0032] When the operator uses the filter device 5, condensate flows in from the inlet 2, first passing through the filter plate 52. The filter holes 53 on its surface act as interceptors, blocking impurities such as dust and rust. The clean condensate continues to enter the drain 1 through the inlet and then exits from the drain outlet 3, completing the filtration process. When the operator needs to replace the filter plate 52, pull the connecting plate 55. Pulling the connecting plate 55 overcomes the elastic force of the spring 56, causing the limiting rod 54 to slide outward, creating space for disassembly of the filter plate 52, making it easy to remove the filter plate 52 from the circular frame 51. After replacing the filter plate 52, place the filter plate 52 onto the circular frame 51 inside the inlet 2, loosen the connecting plate 55, and the spring 56 will push the limit rod 54 back to its original position. Then, firmly press the filter plate 52 back into place to complete the replacement of the filter plate 52. By setting up the filter device 5, the dust, impurities, rust and other particles in the condensate can be effectively intercepted, preventing them from entering the drain 1. This avoids pipe blockage, ensures smooth discharge of condensate, extends the service life of the entire drain 1, reduces maintenance costs and frequency, and also improves the cleanliness of the condensate.
