DETAILED DESCRIPTION

[0024] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figures 1 to 6 As shown, an embodiment of the present invention proposes a water tank for airtight detection of an automobile air-conditioning compressor housing, comprising a water tank body 1, one side of which is provided with a vertical arm 101; an air-drying ring 2, which is arranged on the water tank body 1 and located on the upper side of the water tank body 1, and is used to blow air to the automobile air-conditioning compressor housing; an oil removal device, comprising a scraper 5 movably arranged in the water tank body 1 and a salvaging piece arranged on the vertical arm 101, the scraper 5 can reciprocate and translate in the water tank body 1 to collect oil film, and the salvaging piece can move up and down in the water tank body 1 to salvage the collected oil film.

[0026] The detailed working process of this embodiment is as follows: the oil film on the water surface in the water tank body 1 is cleaned by the oil removal device to ensure the cleanliness of the water in the water tank body 1, so as to facilitate the observation of the air tightness detection effect of the automobile air-conditioning compressor housing, and avoid the problem of the air tightness detection being qualified because of the large amount of oil film covering the water surface. When cleaning the oil film on the water surface in the water tank body 1, the scraper 5 is first used to collect the oil film and drive the oil film to one side of the water tank, and then the salvage piece is driven downward to salvage the oil film. Whenever there is a lot of oil film on the water surface, the above action can be repeated. When the salvage piece is full of the oil film and water mixture, it is removed, and the oil and water are poured out and then installed. It can be reused, avoiding the use of disposable consumables and the problem of waste of resources.

[0027] The air-drying circle 2 can blow air to the automobile air-conditioning compressor housing lifted from the water, blow off the water attached to its surface, reduce the water attached to its surface, and avoid water accumulation in the surrounding environment due to the water on its surface when the automobile air-conditioning compressor housing is moved to the next process.

[0028] like Figure 6 As shown, the air-drying circle 2 includes a main pipe 201 arranged in a ring shape on the water tank body 1, and a plurality of groups of nozzles 202 evenly distributed on the main pipe 201.

[0029] The detailed working process of this embodiment is as follows: the main pipe 201 is externally connected to an air blowing device, and one end of the multiple groups of nozzles 202 can discharge air. The automobile air-conditioning compressor housing that needs to be inspected passes through the middle of the annular main pipe 201. When the inspection is completed, the automobile air-conditioning compressor housing is lifted out of the water. When passing through the main pipe 201, the multiple groups of nozzles 202 blow air to the automobile air-conditioning compressor housing, blowing the water on its surface into the water tank, thereby reducing the amount of water attached to the automobile air-conditioning compressor housing.

[0030] like Figure 6 As shown, one end of each spray head 202 away from the main pipe 201 faces the water tank body 1 and forms an angle with the main pipe 201 .

[0031] The detailed working process of this embodiment is as follows: the nozzles 202 on the main pipe 201 are all tilted downward so that the nozzles 202 and the main pipe 201 form an angle. Within a certain range, the larger the angle, the larger the wind blowing area and the faster the air drying speed.

[0032] like Figure 2 As shown, a screw rod 401 is rotatably provided on two opposite sides of the water tank body 1 and a guide rod 402 is fixedly provided thereon. One end of the scraper 5 passes through the guide rod 402 , and the other end is threadedly connected to the screw rod 401 .

[0033] like Figure 1As shown, one end of the screw rod 401 is transmission-connected to a driving source 4 , and the driving source 4 is disposed on the water tank body 1 .

[0034] The detailed working process of this embodiment is as follows: the function of the screw 401 is to drive the scraper 5 to reciprocate in the water tank, the function of the guide rod 402 is to limit the scraper 5, and the function of the driving source 4 is to drive the screw 401 to rotate. The rotation of the screw 401 drives the scraper 5 to move, thereby driving the scraper 5 to reciprocate in the water tank, making it convenient to concentrate the oil film in the water tank in one place.

[0035] The driving source 4 is a motor. In other embodiments, a suitable driving device can be selected according to actual conditions.

[0036] like Figure 3 and Figure 4 As shown, one-way plates 502 are hinged at both ends of the scraper 5, and baffles 503 are fixedly provided on one side of the two ends of the scraper 5 facing the vertical arm 101. The one-way plates 502 abut against the corresponding baffles 503 in the open state.

[0037] The detailed working process of this embodiment is as follows: the function of the two one-way plates 502 is to prevent the oil film from being concentrated on the back side of the scraper 5 when the scraper 5 returns, resulting in incomplete cleaning. The baffle 503 is normally located on the side of the water tank body 1 away from the salvaged part. When there is a lot of oil film on the water surface, the scraper 5 is driven close to the salvaged part by the screw 401. During this process, the two one-way plates 502 will rotate due to the resistance of the water until they abut against the side walls of the scraper 5. At this time, both ends of the two one-way plates 502 abut against the two side walls of the water tank to form a partition. When moving in this state, when the scraper 5 is moved close to the salvaged part, the oil film on the water surface can be concentrated to one place in the water tank, which is convenient for salvaging. After the oil film is cleaned, the scraper 5 is driven back to the initial position. During the return process, the two one-way plates 502 rotate due to the resistance of the water until they abut against the corresponding baffles 503. At this time, channels are formed on both sides of the scraper 5. During the return process of the scraper 5, the oil film on the back side of the scraper 5 flows out from the channels on both sides, which can ensure that the oil film on the water surface is always between the scraper 5 and the salvaged object.

[0038] like Figure 2 and Figure 5 As shown, the salvage piece includes a stud 303 rotatably mounted at one end on the bottom of the water tank body 1 and rotatably mounted on the vertical arm 101 at the other end, and a driving arm 302 threadedly connected to the stud 303 , on which a collecting bucket 3 is detachably mounted.

[0039] The detailed working process of this embodiment is as follows: the function of the stud 303 is to control the driving arm 302 to move up and down along the direction of the stud 303. The collecting bucket 3 is used to collect the oil film. When in use, the stud 303 is rotated to make the collecting bucket 3 on the driving arm 302 slowly descend until the collecting bucket 3 is submerged in the water. When the opening end of the collecting bucket 3 is just submerged in the water, water will flow into the collecting bucket 3, and the oil film on the water surface can be brought into the collecting bucket 3. It is worth noting that the depth of the opening end of the collecting bucket 3 submerged in the water cannot be too large, otherwise the water will rush in and the function of collecting the oil film will be lost.

[0040] like Figure 2 and Figure 5 As shown, the driving arm 302 includes a mounting seat 3020 threadedly connected to the stud 303 and arc arms 3021 arranged on both sides of the mounting seat 3020, wherein a travel groove 102 is opened on the vertical arm 101, and one end of the mounting seat 3020 is located in the travel groove 102.

[0041] like Figure 5 As shown, each arc-shaped arm 3021 is provided with a limit bar 304 , and both sides of the collecting bucket 3 are provided with limit slots 301 , and each limit bar 304 is clamped in the corresponding limit slot 301 .

[0042] The detailed working process of this embodiment is as follows: the function of the travel groove 102 is to prevent the driving arm 302 from rotating synchronously with the stud 303, thereby affecting the use effect. The arc arms 3021 are all made of elastic material, and the collecting bucket 3 can be clamped between the two arc arms 3021. At the same time, under the setting of the limit bar 304 and the limit groove 301, the collecting bucket 3 is prevented from sliding up and down relative to the two arc arms 3021, affecting the salvage effect. When the collecting bucket 3 is almost full, the collecting bucket 3 is removed from the two arc arms 3021, the oil-water mixture is poured out, and then the collecting bucket 3 is installed on the two arc arms 3021.

[0043] like Figure 3 As shown, one end of the scraper 5 passing through the guide rod 402 is rotatably provided with two limiting rollers 501 , and the guide rod 402 is located between the two limiting rollers 501 and abuts against each other.

[0044] The detailed working process of this embodiment is as follows: when the screw 401 drives the scraper 5 to move, friction will be generated between the scraper 5 and the guide rod 402, affecting the movement stability of the scraper 5. Under the setting of the two limiting rollers 501, the sliding friction between the scraper 5 and the guide rod 402 is converted into rolling friction, avoiding the large friction between the scraper 5 and the guide rod 402 and affecting the movement of the scraper 5.

[0045] The implementation principle of the embodiment of this application is:

[0046] First, during the inspection, the automobile air-conditioning compressor housing is passed through the middle of the annular main pipe 201 and immersed in the water in the water tank for air tightness inspection. After the inspection is completed, the automobile air-conditioning compressor housing is lifted out of the water. When passing through the main pipe 201, multiple groups of nozzles 202 blow air to the automobile air-conditioning compressor housing to blow the water on its surface into the water tank.

[0047] When there is a lot of oil film attached to the water surface in the water tank and needs to be cleaned, the scraper 5 is driven by the screw 401 to approach the collecting barrel 3 to concentrate the oil film on the water surface to one place in the water tank, and then the stud 303 is rotated to make the collecting barrel 3 on the driving arm 302 slowly descend until the collecting barrel 3 is submerged in the water. When the opening end of the collecting barrel 3 is just submerged in the water, water will flow into the collecting barrel 3 and bring the oil film on the water surface into the collecting barrel 3. When the collecting barrel 3 is almost full, the collecting barrel 3 is removed from the two arc arms 3021, the oil-water mixture is poured out, and then the collecting barrel 3 is installed on the two arc arms 3021.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
