Description

Technical Field

[0001] The utility model relates to the technical field of environmental detection, in particular to an air particulate matter detection and collection device. Background Art

[0002] Existing air samplers mainly consist of a diaphragm pump, a regulating valve, a buffer, a flowmeter, a central processing unit, etc. During use, a collection bottle is connected to the sampler body through a rubber tube to collect atmospheric samples, so as to sample and detect environmental air particulate matter.

[0003] For example, an environmental air particulate matter sampling device with a publication number of CN218330809U adjusts the height of the detection bottle upward through an adjustment mechanism, and the locking component fixes the T-shaped rod, so that the detection bottle is far away from the extension frame, facilitating the staff to observe the detection bottle. At this time, the detection bottle is still inside the extension frame, which can protect the detection bottle. After the collection operation is completed, the detection bottle is adjusted downward through the adjustment mechanism, so that the detection bottle is inside the extension frame, facilitating the protection of the detection bottle. However, the adjustment mechanism is arranged on one side of the extension frame. Under the pulling action of the adjustment spring, it is difficult for the bearing plate to move balancedly inside the extension frame, which may lead to the detection bottle being difficult to be pushed out of the extension frame, affecting the normal use of the collection device. Therefore, an air particulate matter detection and collection device is proposed for improvement. Summary of the Utility Model

[0004] The purpose of the utility model aims to solve at least one of the technical defects.

[0005] To this end, an object of the utility model is to propose an air particulate matter detection and collection device to solve the problems mentioned in the background art and overcome the deficiencies existing in the prior art.

[0006] To achieve the above object, an embodiment of one aspect of the utility model provides an air particulate matter detection and collection device, including a sampler. A rubber tube is arranged on the top of the sampler. An extension frame is arranged on one side of the sampler. A support plate is arranged inside the extension frame. A support spring is arranged on the bottom surface of the support plate. A limiting frame is fixedly connected to the middle of the bottom surface of the extension frame. A support sleeve is inserted into the limiting frame. An adjusting rod is threadedly connected inside the support sleeve. The bottom end of the adjusting rod is fixedly connected with a ratchet wheel. A locking tooth is rotatably connected to one side of the limiting frame.

[0007] A limiting ring is fixedly connected to the top of the support plate. A collection bottle is arranged inside the limiting ring. A protective frame is sleeved outside the collection bottle. A support ring is fixedly connected to the bottom end of the protective frame. A pulling spring is arranged between the support ring and the extension frame.

[0008] Preferably, any of the above solutions is that a bracket fixedly connected to the collector is arranged outside the rubber tube, and the end of the rubber tube extends to the upper part of the extension frame.

[0009] Preferably, any of the above schemes is that the bottom end of the support spring is fixedly connected to the bottom surface of the extension frame, and there are a plurality of support springs which are evenly arranged on the bottom surface of the support plate.

[0010] The above technical solution is adopted: a diaphragm pump, a regulating valve, a buffer, a flow meter, a central processing unit and other components are set inside the collector, and a rubber tube is used to connect the collection bottle to the sampler to collect atmospheric samples. A bracket is set on the collector to support the rubber tube. The end of the rubber tube extends to the upper part of the extension frame to facilitate the connection between the rubber tube and the collection bottle. The extension frame provides an installation platform and protection for the collection bottle to avoid damage caused by accidental contact with external objects. The support plate provides support for the collection bottle and can drive the collection bottle to move vertically under the impetus of related structures.

[0011] Preferably, any of the above solutions adopts a non-circular structure for both the limiting frame and the supporting sleeve, and the limiting frame adopts a U-shaped structure.

[0012] Preferably, any of the above schemes is that the top surface of the support sleeve is fixedly connected to the support plate, and the adjustment rod is rotatably connected to the limit frame via a bearing.

[0013] The above technical solution is adopted: the support spring supports the support plate, and a number of support springs are evenly arranged at the bottom of the support plate to ensure the balance and stability of the support plate. The limit frame limits the support sleeve to prevent the support sleeve from rotating with the adjustment rod. When the adjustment rod is rotated, the support sleeve drives the support plate to move vertically under the push of the thread and the constraint of the limit frame, and then drives the collection bottle to move vertically. The limit frame is set in the middle of the support plate, so that the support sleeve supports the middle of the bottom surface of the support plate, so that the support plate can move in a balanced and stable manner.

[0014] Preferably, any of the above schemes is that a turning handle is provided on the bottom surface of the ratchet, and the bottom surface of the locking tooth extends into the tooth opening of the ratchet.

[0015] Preferably, any of the above schemes is that the top of the collecting bottle passes through the extension frame, and the top of the protective frame is fixedly connected to the top of the collecting bottle.

[0016] Preferably, any of the above schemes has a plurality of tie springs which are evenly arranged on the support ring, and an observation window is provided on the inner side surface of the protection frame.

[0017] Adopting the above technical solution: Through the cooperation of the ratchet and the locking teeth, the adjusting rod can be locked, thereby preventing the support sleeve from driving the adjusting rod to reverse under the pulling action of the support spring when the support plate moves downward, realizing the locking of the support sleeve. When the collection bottle moves upward, the protection frame follows the collection bottle to move upward to protect the collection bottle, so that the collection bottle can still be protected by the protection frame even when it exposes the extension frame. By setting an observation window on the protection frame, it is convenient for the staff to observe the collection bottle.
