Abstract
Description
Technical Field
[0001] This utility model relates to the field of water pump welding, and in particular to a device for welding water pump housings. Background Technology
[0002] A water pump is a machine that transports or pressurizes liquids. It transfers the mechanical energy of a prime mover or other external energy to the liquid, increasing the liquid's energy. It is mainly used to transport liquids including water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals.
[0003] As an important component of a water pump, the integrity of the pump casing is crucial for the normal operation of the pump. However, in actual use, due to problems such as material quality issues, pump casing design problems, improper operation, harsh working environment, stress concentration, and material aging, the pump casing may sometimes crack. After workers dismantle and recycle the pump casing with cracks, they will repair the pump casing as needed.
[0004] Because the location of cracks in the water pump casing is random and uncontrollable, repairs are mostly done manually. Commonly, welding torches are used to apply welding rods or wires to the cracks. It is important to note that during welding, the high temperature and strong ultraviolet radiation from the welding arc generate large amounts of toxic gases around the arc zone, such as carbon monoxide and nitrogen oxides. This can easily cause adverse reactions for workers performing repairs in confined spaces.
[0005] In addition, workers need to wear appropriate protective gloves and protective masks during welding to prevent burns to their hands and face. Wearing protective equipment for a long time and having the face covered by the protective mask for a long time puts great pressure on the worker's face and makes it uncomfortable to use.
[0006] Therefore, how to design a welding device for water pump casings that can solve the above-mentioned technical problems is a technical problem that needs to be solved. Utility Model Content
[0007] In order to solve the above problems, the purpose of this utility model is to provide a device for welding water pump housings, so as to facilitate the extraction of toxic gases generated during the welding process and reduce the discomfort of workers.
[0008] To achieve the above objectives, the present invention adopts the following technical solution: including a workbench, a rotating assembly fixed on the workbench, a protective cover fixed on the workbench, and an air intake assembly fixed on the protective cover;
[0009] The workbench includes a base, a support column vertically fixed to the upper surface of the base, and a support plate fixed to the top end of the support column; the upper surface of the support plate is provided with a mounting groove; the rotating assembly includes a drive motor fixed in the base and capable of bidirectional rotation, a connecting plate rotatably disposed in the mounting groove and matching the shape and size of the mounting groove, a rotating shaft whose bottom end is driven and connected to the output end of the drive motor and whose top end is rotatably rotatable through the support column and the support plate and fixedly connected to the connecting plate, two foot pedals fixed on the base, and two sensors respectively fixed in the foot pedals and electrically connected to the drive motor for controlling the rotation direction of the drive motor;
[0010] The protective cover has symmetrical connecting holes on the front side to facilitate the passage of workers' arms. A connecting tube is provided on the inner side wall of the protective cover at the position of the two corresponding connecting holes. A protective glove is movably fitted on the movable end of the connecting tube. The sleeve length of the protective glove is 10-20cm. When in use, the worker's palm is placed on the palm part of the protective glove. The sleeve length of the protective glove is longer than the forearm length of a typical adult, which facilitates the movement of the worker's hand.
[0011] The protective cover has an air outlet at the top, and the air intake assembly includes a fan fixed to the top of the protective cover and connected to the air outlet, and a telescopic hose fixed inside the protective cover and connected to the air outlet.
[0012] Furthermore, the protective cover is hinged with a connecting door.
[0013] Furthermore, a connecting buckle is fixedly provided on the outer side of the protective cover, and a connecting piece that cooperates with the connecting buckle is fixedly provided on the connecting door at the position corresponding to the connecting buckle. The protective cover and the connecting door are connected by the connecting buckle and the connecting piece.
[0014] Furthermore, a sealing strip is fixed at the connection between the connecting door and the protective cover to prevent gas leakage.
[0015] Furthermore, the support plate is equipped with a power source, and a power socket electrically connected to the power source is fixed on the upper surface of the support plate.
[0016] Furthermore, a handle for easy movement of the telescopic hose is fixed to one side of the movable end of the telescopic hose.
[0017] Furthermore, the fan is also connected to a ventilation duct for convenient gas exhaust.
[0018] This utility model has the following beneficial effects:
[0019] 1-This utility model, by setting up an air intake component, allows the water pump housing to be placed flat on the upper surface of the connecting plate during use. The telescopic hose is then pulled down using the handle. The telescopic hose is adjusted according to the height of the water pump and the repair position, so that the air intake end of the telescopic hose is close to the water pump, thereby drawing in harmful gases and minimizing the leakage of harmful gases. This also prevents harmful gases generated during the welding process from affecting workers.
[0020] 2- This utility model is equipped with a rotating component. By stepping on the pedal, the sensor inside the pedal receives pressure and sends a control signal to the drive motor. The control motor then drives the connecting plate to rotate circumferentially via the rotating shaft. This allows workers to control the drive motor to rotate the connecting plate without opening the connecting door, making it easier for workers to observe and repair cracks on the water pump, thus improving its practicality.
[0021] 3- This utility model features a protective cover made of special glass or special plastic. The cover adjusts the light and filters out harmful light from the welding arc, allowing workers to work without wearing protective masks. This avoids the pressure of protective masks on the face during welding work and improves the comfort of workers. Attached Figure Description

The upper surface of the support plate 13 is provided with a mounting groove 131. The rotating assembly 2 includes a drive motor 21 fixed in the base 11 and capable of bidirectional rotation, a connecting plate 22 rotatably disposed in the mounting groove 131 and matching the shape and size of the mounting groove 131, a rotating shaft 23 whose bottom end is driven and connected to the output end of the drive motor 21 and whose top end can rotatably pass through the support column 12 and the support plate 13 and is fixedly connected to the connecting plate 22, two foot pedals 24 fixed on the base 11, and two sensors 25 respectively fixed in the foot pedals 24 and electrically connected to the drive motor 21 for controlling the rotation direction of the drive motor 21.
[0034] The protective cover 3 has symmetrical connecting holes 31 on the front side to facilitate the passage of workers' arms. The inner side wall of the protective cover 3 has connecting tubes 32 connected to the two connecting holes 31. The movable end of the connecting tube 32 is fitted with a protective glove 33. The sleeve length of the protective glove 33 is 10-20cm. When in use, the worker's palm is placed on the palm part of the protective glove 33. The sleeve length of the protective glove 33 is longer than the forearm length of a typical adult, which facilitates the movement of the worker's hand.
[0035] The protective cover 3 has an air outlet 34 on its top. The air intake assembly 4 includes a fan 41 fixed to the top of the protective cover 3 and connected to the air outlet 34, and a telescopic hose 42 fixed inside the protective cover 3 and connected to the air outlet 34.
[0036] Furthermore, the protective cover 3 is hinged to a connecting door 35.
[0037] Furthermore, a connecting buckle 36 is fixedly provided on the outer side of the protective cover 3, and a connecting piece 351 that cooperates with the connecting buckle 36 is fixedly provided on the connecting door 35 at the position corresponding to the connecting buckle 36. The protective cover 3 and the connecting door 35 are connected by the connecting buckle 36 and the connecting piece 351.
[0038] Furthermore, a sealing strip 352 to prevent gas leakage is fixed at the connection between the connecting door 35 and the protective cover 3.
[0039] Furthermore, the support plate 13 is provided with a power supply 132, and the upper end surface of the support plate 13 is fixed with a power socket 133 that is electrically connected to the power supply 132.
