Description

Technical Field

[0001] The utility model discloses a self-cleaning vertical combustion instrument for electric wires and cables, and relates to the field of electric wire and cable testing. Background Art

[0002] Wires and cables are commonly used materials in our daily life. People will conduct various tests on wires and cables to ensure their quality. The vertical combustion test of wires and cables is a test to test the flame retardant performance of a single wire or cable. For the convenience of operation, a vertical combustion instrument for wires and cables is used to test the wires or cables; for example, a single wire and cable vertical combustion instrument is disclosed in Patent Publication No. CN220170969U, which mainly drives the rotating rod to rotate by a rotating rod handle, so that the clapper rotates, so that the clapper hits the cable, thereby removing the carbonized layer from the cable, so that the staff can clearly determine the carbonization point of the cable, which is convenient for the staff to observe, and the fixing frame can be installed in the combustion chamber by using the card block and the card slot, which is convenient for the staff to install or disassemble the fixing frame, and the staff can complete the fixing of the sample outside the device;

[0003] The burner disclosed in the above patent still has shortcomings. After burning the wires or cables, ashes and waste residues will fall directly to the bottom of the body, and the staff is required to hold a rag or a cleaning brush to clean the inside of the body. This not only increases the workload of the staff, but also affects the use effect and efficiency of the equipment. Therefore, it is necessary to design a self-cleaning wire and cable vertical burner to solve the above technical problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a self-cleaning vertical combustion instrument for wires and cables to solve the problems mentioned in the above background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized by the following technical scheme: a self-cleaning vertical combustion instrument for electric wires and cables, comprising a chassis, a combustion chamber arranged inside the chassis, an exhaust duct arranged on one side of the top of the combustion chamber, an igniter installed inside the combustion chamber, and a mounting plate for fixing the electric wires, a flip bottom plate is rotatably installed on the middle axis inside the chassis, and a flip motor for driving the flip bottom plate to flip is installed outside the chassis;

[0006] A cleaning chamber is provided at the lower side of the chassis, and a cleaning assembly for cleaning the bottom surface of a flip bottom plate is provided inside the cleaning chamber, and the flip bottom plate is provided between the combustion chamber and the cleaning chamber;

[0007] One side of the cleaning chamber is connected to a water spray chamber;

[0008] The cleaning component includes a cleaning brush, and a driving screw and a sliding rod horizontally installed in a water spray chamber and a cleaning chamber. The upper brush portion of the cleaning brush can be in close contact with the bottom surface of a flip bottom plate. A connecting plate is fixed to the bottom of the cleaning brush. The driving screw and the sliding rod respectively pass through both sides of the connecting plate, wherein the driving screw is threadedly connected to the connecting plate. A cleaning motor for driving the driving screw to rotate is installed outside the water spray chamber, and is used to drive the cleaning brush to reciprocate and move in the water spray chamber and the cleaning chamber.

[0009] A further improvement is that a plurality of nozzles are installed on the top of the inner side of the water spray chamber, and a connecting water pipe is connected to the outer side of each nozzle, and an external water pump is connected through the connecting water pipe.

[0010] A further improvement is that the spray heads are all arranged toward the cleaning brush, and the bottom of the water spray chamber is arranged to be inclined downward toward one side of the cleaning chamber.

[0011] A further improvement is that a receiving box is provided at the bottom of the cleaning chamber for receiving and collecting waste water and waste materials, and a discharge pipe valve is connected to the bottom of the receiving box for discharging the waste water and waste materials to the outside.

[0012] A further improvement is that a scraping needle plate is vertically installed on the chassis between the water spray chamber and the cleaning chamber, and the scraping needle plate is arranged on the moving path of the cleaning brush.

[0013] A further improvement is that the scraping needle plate is provided with a plurality of needle rods distributed in an array and in close contact with the cleaning brush.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] The utility model is provided with a flip bottom plate which is rotatably arranged in the middle of the chassis body, so that when the igniter in the combustion chamber burns the electric wire on the installation fixing plate, the ashes and waste residues will fall on the flip bottom plate, and when the combustion is finished, the flip bottom plate can automatically flip over to form a new side on the upper side of the flip bottom plate which can continue to be used, while the ashes and waste residues on the bottom surface fall into the receiving box for collection, and the bottom surface of the flip bottom plate after flipping is cleaned and brushed by the provided cleaning component. Specifically, the cleaning brush is driven by the driving screw to reciprocate in the cleaning chamber and the water spraying chamber, so that the cleaning brush is reciprocated along the bottom surface of the flip bottom plate, thereby ensuring its cleanliness;

[0016] At the same time, a scraping needle plate is arranged on the moving path of the cleaning brush, so that when the cleaning brush moves back and forth, each needle bar of the scraping needle plate combs the brush, thereby combing out the waste residue in the brush to ensure the brushing effect of the brush;

[0017] In addition, by arranging multiple nozzles in the water spray chamber to spray water toward the cleaning brush, the high-pressure water flow can quickly penetrate the fibers of the brush, effectively remove attached dirt and residues, and improve the cleaning efficiency. After the cleaning brush is wetted, it can better improve the cleaning effect on the bottom surface of the flip bottom plate, reduce the labor intensity of manual cleaning, and improve work efficiency. Compared with the existing technology, it has a more positive and beneficial use effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] See also Figure 1-Figure 5The utility model provides a technical solution of a self-cleaning vertical burner for electric wires and cables: it comprises a chassis 1, a combustion chamber 2 arranged inside the chassis 1, an exhaust duct 5 arranged on one side of the top of the combustion chamber 2, an igniter 3 installed inside the combustion chamber 2, and a mounting plate 4 for fixing the electric wires, a flip bottom plate 6 is rotatably installed on the middle axis inside the chassis 1, and a flip motor 61 for driving the flip bottom plate 6 to flip is installed on the outside of the chassis 1, the flip bottom plate 6 is used to receive the ashes and waste residues burned in the combustion chamber 2, and is flipped by the flip motor 61, so that the ashes and waste residues fall into the receiving box 10, and the clean surface on the upper side of the flip bottom plate 6 acts as a new receiving surface, so that the surface can be quickly changed to carry out the next combustion process;

[0027] A cleaning chamber 7 is provided at the lower side of the chassis 1, and a cleaning assembly for cleaning the bottom surface of the flip bottom plate 6 is provided inside the cleaning chamber 7. The flip bottom plate 6 is provided between the combustion chamber 2 and the cleaning chamber 7. A water spray chamber 8 is provided on one side of the cleaning chamber 7. The cleaning assembly includes a cleaning brush 71, and a drive screw 72 and a sliding rod 74 horizontally installed in the water spray chamber 8 and the cleaning chamber 7. The upper brush part of the cleaning brush 71 can be in close contact with the bottom surface of the flip bottom plate 6. A connecting plate 712 is fixed to the bottom of the cleaning brush 71.
