Description

Technical Field

[0001] The utility model relates to the technical field of sewage sampling devices, in particular to a sewer sewage collecting device for sewage detection. Background Art

[0002] In municipal construction projects, it is often necessary to test the sewage in the city to ensure the health of urban residents. Before testing the sewage in the sewer, it is often necessary to use a collection device to collect sewage. The existing collection methods mainly include the following two methods:

[0003] 1. Directly manually lower the cable, use the sampling device at the lower end of the cable to reach the sewage in the sewer for sampling, and then manually pull the sampling device out through the cable, which is time-consuming, labor-intensive, and inefficient;

[0004] 2. Chinese patent CN220120429U discloses a sewer sewage collection device for sewage detection, which is supported by a gantry. The motor drives a single traction rope through a winding wheel to drive the movement of the sampling device. During the movement, when the single traction rope drives the sampling device, it shakes greatly, and the sampling device is very easy to collide with the side wall of the sewer, resulting in insufficient sampling volume, requiring multiple samplings, and even causing damage to the sampling device. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a sewer sewage collection device for sewage detection that has high stability, saves manpower and material resources, and has high sampling efficiency.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A sewer sewage collection device for sewage detection, comprising a bracket, the bracket having three arms, the angle between adjacent arms is 180 degrees, and the outer ends of the arms are fixedly mounted with columns downward;

[0008] A traction roller is provided at the lower end of the support arm, and the traction roller is connected to the connecting frame through a bearing, and the connecting frame is fixedly connected to the bracket. A traction rope is wound around the traction roller, one end of the traction rope is fixedly connected to the traction roller, and the other end of the traction rope is fixed to the sampling device. A synchronization structure for driving the three traction rollers to rotate synchronously is installed on the bracket.

[0009] In this way, through the setting of three columns, the supporting effect is improved; when sampling is required, the sampling device moves to the position of the sewer opening, and the synchronous structure drives the three traction rollers to rotate synchronously, so that the traction rope is lowered, and the sampling device reaches the sewage in the sewer to collect the sewage; after the collection is completed, the synchronous structure acts in the reverse direction, driving the traction rollers to wind the traction rope until the sampling device moves above the sewer opening to complete the sampling.

[0010] Through the setting of three traction ropes, the sampling device can be more stable, avoiding collision with the side wall of the sewer and damage.

[0011] Among them, the synchronous structure includes a servo motor fixedly installed on the bracket. The output shaft of the servo motor passes through the bracket downward and is fixedly installed with a driving bevel gear. The end of the traction roller is fixedly installed with a driven bevel gear that can mesh and drive with the driving bevel gear.

[0012] Among them, the sampling device includes a sampling cylinder. The upper end of the sampling cylinder is fixedly installed with a cylinder cover through bolts. An air hole is opened on the cylinder cover. Connecting ears are circumferentially fixed on the sampling cylinder. The traction rope is fixedly connected to the connecting ears. An inlet solenoid valve and an outlet solenoid valve are respectively arranged on the circumferential direction of the lower end of the sampling cylinder and the lower end of the sampling cylinder.

[0013] Among them, a number of arc-shaped reinforcing rods are fixed between one column and the other two adjacent columns.

[0014] Among them, the lower end of the column is fixedly installed with a wheel frame, and a traveling wheel is installed downward on the wheel frame.

[0015] In summary, the sewer sewage collection device for sewage detection of the present invention has the advantages of high stability, saving manpower and material resources, and high sampling efficiency. Brief Description of the Drawings

[0016] Figure 1 It is a schematic structural diagram of a sewer sewage collection device for sewage detection described in the present invention.

[0017] Figure 2 It is Figure 1 a schematic diagram of another orientation. Detailed Description of the Invention

[0018] The present utility model will be further described in detail below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "upper, lower" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation words do not indicate or imply that the devices or components referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present utility model; the orientation words "inner, outer" refer to the inside and outside relative to the contour of each component itself.

[0019] As Figure 1-2 shown, a sewage collection device for sewage detection in a sewer includes a bracket. The bracket has three support arms 1, and the included angle between adjacent support arms is 180 degrees. A column 2 is fixedly installed downward at the outer end of the support arm.

[0020] A traction roller 3 is arranged at the lower end of the support arm. The traction roller is connected to a connecting frame through a bearing, and the connecting frame is fixedly connected to the bracket. A traction rope 4 is wound around the traction roller. One end of the traction rope is fixedly connected to the traction roller, and the other end of the traction rope is fixed to the sampling device. A synchronization structure for driving the three traction rollers to rotate synchronously is installed on the bracket.

[0021] In this way, through the arrangement of the three columns, the support effect is improved; when sampling is required, the sampling device moves to the position of the sewer opening. The synchronization structure drives the three traction rollers to rotate synchronously, so that the traction rope is lowered, and the sampling device reaches the sewage in the sewer to collect the sewage; after the collection is completed, the synchronization structure acts in the reverse direction, driving the traction roller to wind the traction rope until the sampling device moves above the sewer opening to complete the sampling.

[0022] Through the arrangement of the three traction ropes, the sampling device can be more stable, avoiding collision with the side wall of the sewer and damage.

[0023] During implementation, the synchronization structure includes a servo motor 5 fixedly installed on the bracket. The output shaft of the servo motor passes through the bracket downward and is fixedly installed with a driving bevel gear 6. A driven bevel gear 7 that can mesh and drive with the driving bevel gear is fixedly installed at the end of the traction roller. The servo motor drives the driving bevel gear to rotate, and through the meshing of the driving bevel gear and the driven bevel gear, the traction rollers are driven to rotate synchronously.

[0024] During implementation, the sampling device includes a sampling cylinder 8. The upper end of the sampling cylinder is fixedly installed with a cylinder cover through bolts. An air hole is opened on the cylinder cover. Connecting ears 11 are circumferentially fixed on the sampling cylinder. The traction rope is fixedly connected to the connecting ears. An inlet solenoid valve 9 and an outlet solenoid valve 10 are respectively arranged circumferentially at the lower end and the bottom end of the sampling cylinder.

[0025] During sampling, the water inlet solenoid valve on the circumference of the sampling cylinder is opened, and water enters the sampling cylinder through the water inlet solenoid valve. After sampling, the water inlet solenoid valve is closed. When it is necessary to drain the water in the sampling cylinder, just open the water outlet solenoid valve at the lower end of the sampling cylinder.

[0026] Specifically, a storage battery and a controller electrically connected to the storage battery are fixedly installed on the cylinder cover, and a housing is fixed outside the storage battery and the controller. The water inlet solenoid valve, the water outlet solenoid valve, and the servo motor are all connected to the controller and the storage battery.

[0027] During implementation, a number of arc-shaped reinforcing rods 12 are fixed between one column and two adjacent columns.

[0028] During implementation, a wheel frame is fixedly installed at the lower end of the column, and a traveling wheel 13 is installed downward on the wheel frame. It is convenient to move.

[0029] Finally, it should be noted that those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalents, the present utility model is also intended to include these changes and modifications.
